According to the existing technology, the current charging highway adopts the method of laying electrode plates on the road surface, and the vehicle is provided with a charging brush that contacts the electrode plate on the road surface. During driving, the charging brush of the vehicle always contacts the electrode plate to obtain electricity. Recharge the battery in the vehicle, but in this form, the electrode plate is exposed to the outdoor environment and is easily affected by different environments, such as water on the road in rainy days, so that the electrode plate may leak in the liquid, such as people on the road Or animals pass by. If high-voltage electricity is used for power supply, it is easy to cause electric shock accidents, or stones brought by vehicles may also damage the electrode plates. Therefore, more supporting facilities are required to eliminate environmental impact during use, and high-voltage cannot be used. Electric power supply, although the voltage on the electrode plate can be set at a safe voltage value, but if you want to maintain the same power, the current on the electrode plate will become very large, which puts forward quite high requirements for the power supply system.

Based on this, the present invention provides an underground charging device, a charging road, and a charging system thereof. The electrode plate is arranged under the road surface, which can avoid most of the environmental impact, and at the same time, high-voltage electricity can be used to supply power, reducing the cost of corresponding supporting facilities. Construction to reduce the power supply requirements of the power supply system.

The present invention is divided into a device on the vehicle side and a device on the road side, and the two complement each other. In order to facilitate the description, the first aspect and the second aspect of the embodiment are described as a whole, and the basic working method is explained from an overall perspective, and then The specific details of the device on the vehicle side and the device on the road side are separately described in detail.

A first aspect of the embodiments of the present invention provides an underground charging device, comprising:

The telescopic mechanism 100 installed on the vehicle, the telescopic direction of the telescopic mechanism 100 faces the road surface and can extend to the bottom of the road surface, and an electrode plate 500 connected to the power supply system is provided below the road surface, and the electrode plate 500 follows the extension direction of the road surface.

The deployment mechanism 200, one end of the deployment mechanism 200 is fixed on the extension end of the telescopic mechanism 100, and the other end can be deployed under the road surface as a free end;

The charging brush 300 is disposed at the free end of the deployment mechanism 200 and connected to the battery of the vehicle through a charging cable. The charging brush 300 contacts the electrode plate 500 as the deployment mechanism 200 is deployed.

A second aspect of the embodiments of the present invention provides a charging road, comprising:

The underground cavity 400, the underground cavity 400 includes at least one opening 410 for passing through the underground charging device according to any one of claims 1 to 6, the opening 410 is opened on the upper side of the underground cavity 400, and the upper side of the underground cavity 400 forming a water retaining structure 420 with the road surface;

The electrode plate group includes two electrode plates 500, the electrode plates 500 are arranged under the water blocking structure 420 and/or on the side wall adjacent to the water blocking structure 420, the electrode plate 500 is connected to the power supply system, and the electrode plate group is arranged along the road surface. The extension direction extends.

Referring to FIG. 1 to FIG. 4 , from the cross-section of the charging road, the charging road has an opening 410 through which the telescopic mechanism 100 can pass. When viewed in the extending direction of the charging road, the opening 410 extends along the extending direction of the road surface. The slot is equivalent to forming a charging track. The vehicle drives the telescopic mechanism 100 to travel along the charging track. As long as the charging brush 300 can take electricity from the electrode plate 500 and the rechargeable battery in the vehicle works normally, the vehicle can be charged in the present invention. It is charged while driving on the road; it should be noted that the rechargeable battery in the vehicle currently has two charging modes: DC and AC, and the corresponding electrode plate 500 can also be powered by DC or AC, but it is obviously necessary to distinguish between multiple lanes , such as DC lanes, AC lanes, and each charging lane is set in parallel according to the lane division of ordinary roads.

It is worth noting that, in order to prevent the telescopic mechanism 100 from colliding with the opening 410, the above solution also needs to consider the alignment of the vehicle's driving direction with the charging track. Since the road needs to be reserved to carry the wheels through, the opening 410 cannot be opened too much. It is slightly wider than the width of the telescopic mechanism 100 at the position of the opening 410, which requires the vehicle to basically travel along the charging track without major deviation. Here, the vehicle is provided with a corresponding detector, such as radar or microwave The detection device obtains the position of the charging track at the bottom of the vehicle or in front of the vehicle in real time, and automatically adjusts the driving direction of the vehicle. For example, the unmanned vehicles that have appeared so far, it is not difficult to achieve this function, which will not be described in detail here. If the telescopic mechanism 100 is completely fixed on the bottom of the vehicle and does not move relative to the bottom of the vehicle, even if the vehicle can adjust the driving direction in real time, there is still a certain risk of collision. The present invention only points out a possible solution here. 10 and 11, the perspective in the figures is from the inside of the vehicle to the road, the telescopic mechanism 100 is connected with a slide rail 600, the length direction of the slide rail 600 is perpendicular to the straight running direction of the vehicle, and the telescopic mechanism 100 can move along the slide rail 600 It is offset by a certain distance, and a sensor for detecting the offset is set to monitor the offset of the telescopic mechanism 100 on the sliding rail 600. When the vehicle slightly deviates from the driving direction, the telescopic mechanism 100 can move on the sliding rail 600, and automatically adjust to the sliding rail 600. For the quasi-opening 410 , as long as the maximum offset of the telescopic mechanism 100 on the slide rail 600 is not exceeded, the telescopic mechanism 100 will not collide violently with the edge of the opening 410 .

The structure of the charging road is described in detail below:

In one embodiment, the two electrode plates 500 in the electrode plate group are located in the same underground cavity 400 , the opening 410 is located in the middle of the upper side of the underground cavity 400 , and two water blocking structures 420 are formed on both sides of the opening 410 .

The charging road in this embodiment has a structure of a single charging track. Referring to FIG. 5 , two electrode plates 500 are located on both sides of the opening 410 respectively, and the two charging brushes 300 of the underground charging device extend from the opening 410 into the rearward direction. The electrode plates 500 are respectively unfolded; preferably, the underground cavity 400 is located in the center of the charging highway, and the opening 410 is located in the center of the upper side of the underground cavity 400 as viewed from the cross section of the charging highway.

In order to prevent rainwater and the like from falling into the underground cavity 400 from the opening 410 due to gravity, the inside of the charging road is inclined downward from the opening 410 to both sides, so that the height of the opening 410 is slightly higher than the two sides, which has little effect on the driving of the vehicle. influences.

In another embodiment, the number of underground cavities 400 is two, only one electrode plate 500 is provided in one underground cavity 400, and the two underground cavities 400 are separated.

The charging road in this embodiment has a structure of double charging rails, and concrete is used to replace the two parallel charging rails. Therefore, the charging road is divided into three parts by the dual charging rails, and the middle part has two forms. The first type Referring to Fig. 6, the water retaining structure 420 is connected with the middle part, so that the middle structure forms a T shape, and the second form is referring to Fig. 7, the water retaining structure 420 is connected with the road surface on both sides, so that the middle structure forms a rectangle, correspondingly, In order to be able to contact the electrode plates 500 at different positions, the unfolding direction of the unfolding mechanism 200 needs to be adjusted to a certain extent, and its specific structure will be described in detail later.

Likewise, in order to prevent rainwater and the like from falling into the underground cavity 400 from the opening 410 due to gravity, the road surfaces on both sides of the charging highway in this embodiment are inclined downward from the middle position to both sides.

In one embodiment, the water blocking structure 420 includes a waterproof lower edge 430, and the waterproof lower edge 430 is disposed beside the opening 410 and extends toward the underground cavity 400 along the road. The waterproof lower edge 430 in this embodiment is used to prevent objects falling into the underground cavity 400 from scattering in the cavity. The structure composed of the waterproof lower edge 430 and the opening 410 is equivalent to a short tube, which can guide the falling objects. objects, reducing the difficulty of cleaning the underground cavity 400, and at the same time preventing a part of large objects from entering the opening 410 obliquely.

In one embodiment, the bottom of the underground cavity 400 constitutes a drainage ditch 440, and the drainage ditch 440 extends along the extending direction of the road surface and is provided with a drainage port 441 or a cleaning port at intervals. Since the underground cavity 400 extends along the extending direction of the road like the electrode plate 500, the underground cavity 400 actually forms a channel as long as the charging road. In order to clean the sundries, sewage, etc. in the underground cavity 400 , the bottom of the underground cavity 400 is used as the drainage ditch 440; it is worth noting that the environment of different regions is different, and the depth of the drainage ditch 440 is also different. The drainage ditch 440 can be made deeper; with reference to FIG. 9 , in this embodiment, the cleaning method of the drainage ditch 440 can use a cleaning robot in addition to the drainage port 441 or the sewage outlet as mentioned above. A robot entrance is set up at intervals, and the cleaning robot starts regularly or on demand to clean the drainage ditch 440 of this section, and returns to the robot entrance for maintenance after cleaning.

In order to improve the bonding degree between the electrode plates 500, in one embodiment, two adjacent electrode plates 500 are butted end to end along the extending direction of the road surface, and two adjacent water blocking structures 420 are butted end to end along the extending direction of the road surface. The water structure 420 is provided with a groove 421 perpendicular to the extending direction of the road surface beside the butt joint, and two adjacent grooves 421 are fastened by concave asphalt pieces 422 . Referring to FIG. 8, FIG. 8 shows a cross-sectional view of the junction of the charging road parallel to the extending direction of the road surface, the grooves 421 of the two water retaining structures 420 and the concave asphalt pieces 422 are engaged with each other, and the two The side protrusions are equivalent to locking the two water blocking structures 420 , which can strengthen the structural strength between the water blocking structures 420 and reduce the damage to the road surface caused by heavy vehicles.

The structure of the underground charging device is described in detail below:

In combination with the above-mentioned embodiment of a single charging track, that is, the road surface has an opening 410, the underground charging device of the present invention adopts the following structure: In an embodiment, the deployment mechanism 200 includes a swing arm 210 and a first rotation mechanism 220, One end is rotatably connected to the extension end of the telescopic mechanism 100 as a rotating end, and the other end is connected to the charging brush 300 as a free end. The first rotation mechanism 220 includes a pull rope 221 and a return spring 222. One end of the pull rope 221 is fixedly connected to the swing arm 210, and the other end is connected to the traction mechanism in the vehicle around the extension end of the telescopic mechanism 100. The return spring One end of the 222 is fixedly connected to the swing arm 210 , and the other end is connected to the side wall of the telescopic mechanism 100 .

According to the distribution of the electrode plates 500 in the charging road, the number of the charging brushes 300 is also two. Since the electrode plates 500 are distributed on both sides of the opening 410 , the unfolding direction of the charging brushes 300 is from the middle to both sides, and the telescopic mechanism As an example, referring to FIG. 1 , when the telescopic mechanism 100 is in a retracted state, the pull cord 221 is pulled upward, the return spring 222 is pulled away, and the brush head of the charging brush 300 faces the road surface. When the underground charging device starts to work, the telescopic mechanism 100 extends the charging brush 300 into the underground cavity 400, then releases the pull rope 221, and the return spring 222 retracts and pulls the swing arm 210 to expand to both sides, that is, swing The arm 210 is lifted from the lowest point, so that the charging brush 300 contacts the electrode plate 500 in the underground cavity 400. When the rechargeable battery in the vehicle recognizes the power supply from the electrode plate 500, the electronic control system of the vehicle stops loosening the pull rope 221 , so that the swing arm 210 is stopped at the current angle, and stable contact between the electrode plate 500 and the charging brush 300 is achieved. When it is necessary to end the charging, the pull cord 221 is retracted upward, so that the retractable mechanism 100 returns to the retracted state.

It is worth noting that, according to the description of the structure of the electrode plate 500 in the charging highway, the electrode plate 500 can be disposed under the water blocking structure 420 and/or on the side wall adjacent to the water blocking structure 420, so according to the different actual application scenarios , the electrode plate 500 can be arranged in different positions.

On the other hand, the underground charging device of the present invention does not specify which part of the vehicle to be fixed on. Generally speaking, the underground charging device is fixed on the bottom of the vehicle, but considering that the chassis of some vehicles is low, the interior space of the vehicle cannot be stored. The long telescopic mechanism 100 can fix the underground charging device on the front side of the vehicle, which also facilitates the detection of the charging track by devices such as sensors.

In combination with the above-mentioned embodiment of dual charging rails, that is, the road surface has two openings 410, the above-mentioned underground charging device in the form of swing arm 210 will make changes in the orientation direction. Referring to FIG. 2, two telescopic mechanisms 100 need to be installed on the vehicle and each A single charging brush 300 is connected to each telescopic mechanism 100, and the two telescopic mechanisms 100 are respectively inserted into the two underground cavities 400. In this case, the operation of the underground charging device is similar to the above, and will not be repeated here.

Based on the above-mentioned underground charging device in the form of the swing arm 210 , in one embodiment, the deployment mechanism 200 further includes a baffle 223 for preventing the swing arm 210 from over-swinging, and the baffle 223 is disposed beside the rotating end of the swing arm 210 and located On the side away from the free end of the swing arm 210 , the baffle plate 223 extends below the road surface along the extension end of the telescopic mechanism 100 . Since the adjustment of the pull rope 221 and the return spring 222 has a certain limit, in order to ensure that the swing arm 210 will not swing beyond the limit angle when it is retracted, the baffle 223 can be used to prevent the swing arm 210 from swinging. In this embodiment, The baffle 223 extends along the longitudinal direction of the telescopic mechanism 100 .

In addition to the deployment mechanism 200 in the form of the swing arm 210, as another embodiment, the deployment mechanism 200 may also take the following forms:

The unfolding mechanism 200 includes a rotatable base 230 and a second rotating mechanism 240. The rotatable base 230 is in the shape of a bar, and the center of the rotatable base 230 is connected to the extending end of the telescopic mechanism through the second rotating mechanism 240. The charging brush 300 It is arranged on both sides of the rotatable base 230 .

This embodiment is suitable for charging roads with a single charging track, because the rotatable base 230 can rotate around the second rotating mechanism 240. In the initial state, that is, the vehicle does not put the underground charging device down, the length of the rotatable base 230 The direction is the same as the extending direction of the charging track. It can be seen from this that the width of the rotatable base 230 is smaller than the width of the opening 410. When the vehicle needs to be charged on the charging road, the telescopic mechanism 100 puts down the rotatable base 230 so that the rotatable base 230 can be rotated. The base 230 enters the underground cavity 400 through the opening 410 , and then the rotatable base 230 is rotated by 90 degrees. At this time, the charging brush 300 can contact the electrode plate 500 under the water blocking structure 420 . It should be noted that this embodiment provides the form of fixing the second rotating mechanism 240 on the rotatable mechanism, that is, the telescopic mechanism 100 cannot be rotated, which reduces the design complexity of the telescopic mechanism 100, and the second rotating mechanism 240 can be a rotating motor , and connect the vehicle's electronic control system through wires or wireless to realize action control.

Similarly, based on the underground charging device in the form of the rotatable base 230, the telescopic mechanism 100 can have various forms. The type telescopic rod is a common form of telescopic rod, which will not be described in detail here, while the edge-toothed telescopic rod, referring to Figure 3, uses a combination of gears and racks to fix the gears on the vehicle, and the racks are meshed with the gears and connected at one end. The second rotating mechanism 240 on the rotatable base 230 can control the rotation of the gear, so that the rack can move up and down, so as to achieve a telescopic effect; while the spring-type return lever, referring to FIG. In the combination of push rods, one end of the fixed-length rod is connected to the output shaft of the short-range electric push rod, and the other end is connected to the rotatable base 230, and the spring is connected in series on the output shaft of the short-range electric push rod to provide ejection thrust.

A third aspect of the embodiments of the present invention provides a charging system, including the underground charging device of any of the above embodiments and the charging road of any embodiment. If a vehicle equipped with the underground charging device enters the charging road and requests charging, the charging The electric brush 300 is driven by the telescopic mechanism 100 and extends into the underground cavity 400 , and the charging brush 300 is driven by the expansion mechanism 200 and is in contact with the electrode plate 500 .

Due to the limitation of the charging track, the charging system of the present invention is more suitable for vehicles running on a fixed track or other road vehicles, such as electric buses, heavy-duty electric vehicles, etc. The power taking device on the vehicle is simplified, and the current on the electrode plate 500 is relatively small; on the other hand, since the electrode plate 500 is arranged underground, the influence of harsh environments such as rainy days can be effectively avoided. The telescopic mechanism 100 of the present invention is composed of The vehicle extends to the bottom of the road, and the charging brush 300 is sent under the road to contact the electrode plate 500 to provide power for the vehicle, so that the moving vehicle can continue to contact the electrode plate 500 to achieve the effect of charging while driving. In the road section, the vehicle folds the telescopic mechanism 100 without affecting the normal driving. Since the electrode plate 500 can be charged with high voltage, it cooperates with the charging brush 300 on the vehicle to realize the charging of the vehicle while driving, which reduces the use of supporting measures and reduces the Construction costs, improve safety performance.
