- the cleaning device sprays fluid to prevent foreign matter from adhering to the partition.
- liquid such as raindrops adheres to the area near the first opening of the cleaning device, it may get caught in the flow of fluid sprayed from the first opening, causing a large amount of liquid to be sprayed onto the partition.
- the liquid sprayed onto the partition may block the sensor's view as a foreign matter, reducing the sensor's ability to obtain information.
- Raindrops that adhere to the upper surface of the cleaning device tend to aggregate with other raindrops. Raindrops that have gained weight due to aggregation are more likely to move downward.

- liquid such as raindrops adheres to the area near the first opening of the cleaning device, it may get caught in the flow of fluid sprayed from the first opening, causing a large amount of liquid to be sprayed onto the partition.
- the liquid sprayed onto the partition may block the sensor's view as a foreign matter, reducing the sensor's ability to obtain information.
- Liquid such as raindrops may come from the front due to external air currents or being kicked up by a preceding vehicle. In this case, the liquid may directly approach the first opening without passing through part of the cleaning device.
- liquid coming from the front of the cleaning device is encouraged to adhere to the first wall portion.

- FIG. 1 illustrates an example of the exterior of the sensor assembly 1 according to the first embodiment, as viewed from the right.
- the sensor assembly 1 includes a camera 11.
- the camera 11 comprises a housing 111, an image sensor 112, and a lens 113.
- the housing 111 houses the image sensor 112.
- the housing 111 supports the lens 113 in front of the image sensor 112.
- the lens 113 focuses light coming from a subject positioned at least in front of the camera 11 on the light receiving surface of the image sensor 112.
- the image sensor 112 is configured to output a signal according to the brightness of the optical image. Examples of the image sensor 112 include a CCD sensor and a CMOS sensor.
- the image sensor 112 is an example of a sensor.
- the lens 113 is an example of a partition.
- the sensor assembly 1 includes a bracket 12.
- the sensor assembly 1 is mounted on a vehicle 3 as shown in FIG. 2.
- the bracket 12 is a member for supporting the sensor assembly 1 at an appropriate location on the vehicle 3.
- the shape of the vehicle 3 is merely an example.
- the number and arrangement of sensor assemblies 1 mounted on vehicle 3 are determined appropriately according to the subject for which imaging is required.
- a front part 31, a left side part 32, a right side part 33, and a rear part 34 of vehicle 3 are illustrated. Therefore, the front-rear direction, left-right direction, and up-down direction of sensor assembly 1 do not necessarily coincide with the front-rear direction, left-right direction, and up-down direction of vehicle 3, respectively.
- line V extends vertically
- line H extends horizontally
- a detection reference axis X extending forward from the imaging element 112 is oriented horizontally or downwardly when the sensor assembly 1 is mounted on the vehicle 3.
- the detection reference axis X defines the reference direction of imaging performed by the imaging element 112.
- the detection reference axis X may be set to correspond to the optical axis of the lens 113.
- the sensor assembly 1 is equipped with a cleaning device 13.
- the cleaning device 13 is a device that prevents foreign matter from adhering to the lens 113 of the camera 11 by spraying air A toward the lens 113.
- Air A is an example of a gas or a fluid.
- Figure 3 shows an example of the appearance of the cleaning device 13 as seen from the lower left front.
- the cleaning device 13 has a first part 131 and a second part 132.
- the first part 131 is formed with a first opening 1311 that sprays air toward the lens 113.
- a first duct 1321 is formed that guides air toward the first part 131.
- the first pipeline 1321 extends along the detection reference axis X of the image sensor 112 so that the front end is positioned lower than the rear end.
- the first opening 1311 is positioned lower than the first pipeline 1321.
- the cleaning device 13 sprays air A to prevent foreign matter from adhering to the lens 113.
- liquid such as raindrops adheres near the first opening 1311 of the cleaning device 13, it may be caught in the flow of air A sprayed from the first opening 1311, causing a large amount of liquid to be sprayed onto the lens 113.
- the liquid sprayed onto the lens 113 may act as foreign matter and block the field of view of the imaging element 112, reducing the ability to obtain information.
- Various measures are adopted in the sensor assembly 1 to prevent such an occurrence.
- the symbol R11 indicates an example of a path along which liquid such as raindrops adhering to the upper surface of the cleaning device 13 may move.
- Raindrops adhering to the upper surface tend to aggregate with other raindrops.
- Raindrops that have gained weight due to aggregation tend to move downward.
- the detection reference axis X of the imaging element 112 extending forward is oriented downward rather than horizontally, there is a higher possibility that the liquid will reach the vicinity of the first opening 1311 that sprays air A toward the lens 113 located in front of the imaging element 112.
- upper surface means a surface having a portion whose normal direction faces upward relative to the horizontal.
- FIG. 4 illustrates the external appearance of the sensor assembly 1 as viewed from above.
- the left edge 132a of the second part 132 has a portion that extends further to the right than the left end 131a of the first part 131 when viewed from the first direction.
- the right edge 132b of the second part 132 has a portion that extends further to the left than the right end 131b of the first part 131 when viewed from the first direction.
- This configuration reduces the area of the top surface of the cleaning device 13 on which raindrops can adhere, reducing the possibility that raindrops will aggregate and approach the first opening 1311. This prevents the air A sprayed toward the lens 113 from blowing liquid such as raindrops onto the lens 113, thereby reducing the imaging capability of the imaging element 112.
- the first portion 131 is formed with a second opening 1312 for spraying cleaning liquid toward the lens 113.
- the cleaning device 13 includes a third portion 133.
- a second pipeline 1331 is formed inside the third portion 133 to guide the cleaning liquid toward the first portion 131.
- the second pipeline 1331 also extends along the detection reference axis X of the image sensor 112 so that its front end is positioned lower than its rear end.
- the second opening 1312 is positioned lower than the second pipeline 1331.
- a gap 134 is formed between the second portion 132 and the third portion 133. This configuration also reduces the area of the top surface of the cleaning device 13 onto which raindrops may adhere, further reducing the possibility of raindrops coagulating and approaching the first opening 1311.
- the gap 134 is formed so as to be located behind the lens 113. With this configuration, liquid such as raindrops that pass through the gap 134 from above and adhere to the camera 11 are less likely to be caught up in the flow of air A that is sprayed toward the lens 113. This further reduces the occurrence of a situation in which the imaging capability of the imaging element 112 is reduced due to liquid such as raindrops being blown against the lens 113 by air A.
- the first opening 1311 is disposed above the lower end 131c of the first portion 131.
- the possibility of the liquid adhering to the first opening 1311 located above it can be reduced, thereby suppressing the possibility of the liquid being blown by air A toward the lens 113.
- the first upper surface 131d of the first portion 131 has a shape in which both ends in the left-right direction are positioned lower than the portion located directly above the location where the first opening 1311 is formed.
- the symbol R12 indicates an example of a path along which liquid such as raindrops adhering to the first upper surface 131d moves.
- liquid such as raindrops adhering to the upper surface of the cleaning device 13 can approach the first opening 1311 via the front end of the cleaning device 13. This tendency is particularly pronounced in configurations in which the detection reference axis X of the imaging element 112 extending forward is oriented downward rather than horizontally.
- the first upper surface 131d has the shape described above, liquid that adheres to or reaches the portion located directly above the first opening 1311 is encouraged to move in the left-right direction. This reduces the possibility that liquid such as raindrops will reach the first opening 1311 by passing through the front end of the cleaning device 13. This prevents the image capturing capability of the image sensor 112 from being reduced by liquid being blown onto the lens 113 by air A jetted toward the lens 113.
- FIG. 6 shows another example of the shape of the first upper surface 131d of the first portion 131. As long as both left and right ends are located lower than the portion located directly above where the first opening 1311 is formed, the first upper surface 131d does not need to have a flat portion.
- the first upper surface 131d of the first portion 131 may have a shape in which one of the two left-right ends is located lower than the portion located directly above the location where the first opening 1311 is formed.
- the portion located directly above the location where the first opening 1311 is formed does not have to be the highest position on the first upper surface 131d. In this case, it is preferable that the end farther away from the first opening 1311 is located lower.
- the cleaning device 13 is equipped with a guide member 135.
- the guide member 135 extends in the vertical direction so as to be connected to the first part 131 and the second part 132.
- the lower end 135a of the guide member 135 is located below the first opening 1311.
- the guide member 135 is positioned so as to contact the housing 111 of the camera 11 behind the lens 113.
- the symbol R13 indicates another example of the movement path of liquid such as raindrops adhering to the cleaning device 13.
- Liquid adhering to the lower part of the cleaning device 13 or liquid descending from the upper part of the cleaning device 13 can move along the underside of the cleaning device 13.
- the detection reference axis X of the imaging element 112 extending forward is directed downward rather than horizontally, there is a higher possibility that the liquid will reach the vicinity of the first opening 1311 that sprays air A toward the lens 113 located in front of the imaging element 112.
- the guide member 135 contacts the housing 111 of the camera 11 behind the lens 113, liquid approaching the first opening 1311 in the cleaning device 13 is urged to move to the housing 111 along the path indicated by the symbol R14.
- the lower end 135a of the guide member 135 contacts the housing 111 below the first opening 1311, the possibility of liquid that has moved to the housing 111 reaching the first opening 1311 can be reduced. This makes it possible to prevent a situation in which the imaging capability of the imaging element 112 is reduced due to liquid being blown onto the lens 113 by air A jetted toward the lens 113.
- the guide member 135 is formed so as to be connected to both the first portion 131 and the second portion 132.
- the guide member 135 can be formed so as to be connected to at least one of the first portion 131 and the second portion 132.
- the guide member 135 can be formed so as to be connected only to the first portion 131.
- the guide member 135 is arranged so as to come into contact with the housing 111 of the camera 11 to the left and right of the lens 113.
- a configuration in which a single guide member 135 is provided so as to come into contact with the housing 111 of the camera 11 to either the left or right of the lens 113 can also be adopted.
- This configuration reduces the possibility that the liquid descending from the lower end 135a of the guide member 135 to the housing 111 will reach the lens 113, further reducing the occurrence of a situation in which the imaging capability of the imaging element 112 is reduced due to the liquid being sprayed onto the lens 113.

- a first duct 2321 is formed that guides air toward the first part 231.
- the first pipeline 2321 extends along the detection reference axis X of the image sensor 112 so that the front end is positioned lower than the rear end.
- the first opening 2311 is positioned lower than the first pipeline 2321.
- the cleaning device 23 sprays air A to prevent foreign matter from adhering to the lens 113.
- liquid such as raindrops adheres near the first opening 2311 of the cleaning device 23, it may be caught in the flow of air A sprayed from the first opening 2311, causing a large amount of liquid to be sprayed onto the lens 113.
- the liquid sprayed onto the lens 113 may act as foreign matter and block the field of view of the imaging element 112, reducing the ability to obtain information.
- Various measures are adopted in the sensor assembly 2 to prevent such an occurrence.
- R21 is an example of a path along which liquid such as raindrops adhering to the upper surface of the cleaning device 23 may move.
- Raindrops adhering to the upper surface tend to aggregate with other raindrops.
- Raindrops that have gained weight due to aggregation are more likely to move downward.
- the detection reference axis X of the imaging element 112 extending forward is oriented downward rather than horizontally, there is a greater possibility that liquid such as raindrops may reach the vicinity of the first opening 2311 that sprays air A toward the lens 113 located in front of the imaging element 112.
- the left edge 232a of the second part 232 as viewed from a first direction along the up-down direction of the cleaning device 23 has a portion that extends further to the right than the left end 231a of the first part 231 as viewed from the first direction.
- the right edge 232b of the second part 232 as viewed from the first direction has a portion that extends further to the left than the right end 231b of the first part 231 as viewed from the first direction.
- This configuration reduces the area of the top surface of the cleaning device 23 on which raindrops can adhere, reducing the possibility that raindrops will aggregate and approach the first opening 2311. This prevents the air A sprayed toward the lens 113 from blowing liquid such as raindrops onto the lens 113, thereby reducing the imaging capability of the imaging element 112.
- the second portion 232 has a second upper surface 232c.
- a front end 232d of the second upper surface 232c is connected to the front end of the cleaning device 23.
- the second upper surface 232c has a left recess 232e and a right recess 232f located below the front end 232d.
- the left recess 232e is connected to a portion of the left edge 232a of the second part 232 that extends further to the right than the left end 231a of the first part 231.
- the right recess 232f is connected to a portion of the right edge 232b of the second part 232 that extends further to the left than the right end 231b of the first part 231.
- the liquid accumulating in the left recess 232e is encouraged to move to the left.
- the liquid accumulating in the right recess 232f is encouraged to move to the right. This encourages the liquid adhering to the second upper surface 232c to move along the path illustrated by the symbol R22 in FIG. 11 before it reaches the front end of the cleaning device 23. As a result, the possibility of the liquid reaching the first opening 2311 can be further reduced.
- FIG. 14 illustrates an example of the appearance of the sensor assembly 2 as seen from the front.
- the first upper surface 231c of the first part 231 of the cleaning device 23 has a shape in which both left and right ends are located lower than the portion located directly above the location where the first opening 2311 is formed.
- the symbol R23 indicates an example of a path along which liquid such as raindrops adhering to the first upper surface 231c moves.
- liquid such as raindrops adhering to the upper surface of the cleaning device 23 can approach the first opening 2311 via the front end of the cleaning device 23.
- This tendency is particularly pronounced in configurations in which the detection reference axis X of the imaging element 112 extending forward is oriented downward rather than horizontally.
- the first upper surface 231c has the above-mentioned shape, liquid that adheres to or reaches the portion located directly above the first opening 2311 is encouraged to move in the left-right direction. This reduces the possibility that liquid such as raindrops will reach the first opening 2311 by passing through the front end of the cleaning device 23. This prevents the image capturing capability of the image sensor 112 from being reduced by liquid being blown onto the lens 113 by air A jetted toward the lens 113.
- the left end 231d of the first upper surface 231c is located to the left of the left end of the lens 113.
- the right end 231e of the first upper surface 231c is located to the right of the right end of the lens 113. Note that only one of the left end 231d and the right end 231e of the first upper surface 231c may be disposed to the side of the lens 113.
- This configuration reduces the possibility that the liquid that is encouraged to move left and right along the first upper surface 231c will fall and reach the lens 113, further reducing the occurrence of a situation in which the imaging capability of the imaging element 112 is reduced due to the liquid being sprayed onto the lens 113.
- the first upper surface 231c of the first portion 231 may have a shape in which one of the two left-right ends is located lower than the portion located directly above the location where the first opening 2311 is formed.
- the portion located directly above the location where the first opening 2311 is formed does not have to be the highest position on the first upper surface 231c. In this case, it is preferable that the end farther away from the first opening 2311 is located lower.
- the first opening 2311 is disposed above the lower end 231f of the first portion 231.
- the possibility of the liquid adhering to the first opening 2311 located above it can be reduced, thereby suppressing the possibility of the liquid being blown by air A toward the lens 113.
- the first portion 231 is formed with a second opening 2312 for spraying cleaning liquid toward the lens 113.
- a second pipeline 2322 is formed for directing cleaning liquid toward the first portion 231.
- the second pipeline 2322 also extends along the detection reference axis X of the image sensor 112 so that its front end is positioned lower than its rear end.
- the second opening 2312 is positioned lower than the second pipeline 2322.
- the first opening 2311 is disposed above the center of the lens 113 in the left-right direction.
- the second opening 2312 is disposed above the lens 113 to the left of the center.
- the first opening 2311 is formed above the second opening 2312. This configuration reduces the possibility that the cleaning liquid sprayed from the second opening 2312 will adhere to the first opening 2311. This makes it possible to prevent the cleaning liquid from being sprayed onto the lens 113 at an unintended time by the air A sprayed from the first opening 2311.
- the above positional relationship between the first opening 2311 and the second opening 2312 can also be applied to the first opening 1311 and the second opening 1312 in the cleaning device 13 according to the first embodiment.
- both ends of the second upper surface 232c of the second portion 232 in the left-right direction are located lower than the central portion 232g in the same direction.
- liquid such as raindrops adhering to the upper surface of the cleaning device 23 is encouraged to move in the left-right direction before it reaches the front end of the cleaning device 23. This further reduces the possibility that liquid such as raindrops will reach the first opening 2311 via the front end of the cleaning device 23.
- FIG. 15 illustrates an example of the appearance of the cleaning device 23 as viewed from the upper left rear.
- the first pipe 2321 is disposed closer to the center 232g of the second upper surface 232c than the second pipe 2322.
- the first pipe 2321 is disposed higher than the second pipe 2322.
- This configuration makes it easy to efficiently form the shape of the second upper surface 232c, in which both ends in the left-right direction are located lower than the center portion 232g. In addition, it makes it easy to efficiently realize the above-mentioned arrangement in which the second opening 2312 is located lower than the first opening 2311.
- Figure 16 shows an example of the external appearance of the sensor assembly 2 as seen from the lower left front.
- the rear of the second part 232 of the cleaning device 23 is in contact with the upper surface of the housing 111 of the camera 11 with no gap.
- the front of the second part 232 faces the housing 111 with a gap that is at least large enough to prevent capillary action from occurring.
- This configuration reduces the possibility of liquid, such as raindrops, penetrating between the bottom surface of the cleaning device 23 and the top surface of the housing 111 of the camera 11 and approaching the first opening 2311 through capillary action.
- the sensor assembly 2 can be mounted on the vehicle 3 so that it is covered by the vehicle body part 35 from at least above. This configuration can reduce the possibility that liquid such as raindrops will adhere to the cleaning device 23 from at least above.
- the cleaning device in each embodiment sprays air A to prevent foreign matter from adhering to the lens 113.
- a gas or liquid having a specific composition may also be sprayed.
- the gas or liquid is an example of a fluid.
- the sensor assembly may include a sensor other than the imaging element 112.
- sensors include a light receiving element in a LiDAR (Light Detection and Ranging) device, a receiving element in a millimeter wave radar, and a receiving element in an ultrasonic sensor.
- the cleaning device is used to suppress adhesion to the bulkhead located in front of each sensor. Depending on the type of sensor, the bulkhead does not need to be transparent to visible light.
- the sensor assembly according to each embodiment may be mounted on a moving body other than a vehicle 3.
- Examples of other moving bodies include trains, airplanes, flying objects, ships, etc.
- the moving body may not require a driver.
