[Industrial applications]

 The present invention relates to a vehicle-mounted electronic device detachably attached to a vehicle bracket by pulling out a handle.

[0002]

[Prior art]

 As an anti-theft device for this type of in-vehicle electronic device, there is one that is detachably attached to a bracket formed on a car. That is, the engaging means is provided between the bracket of the car and the electronic device, and is fixed by the engaging means in the mounted state, and when detached from the bracket, the engaging means is engaged by pulling out the handle provided on the electronic device. It is configured to release the match and leave.

FIG. 6 shows the structure of a conventional vehicle-mounted electronic device that is detachably attached to a vehicle. The vehicle not shown is provided with a dashboard 3, and the dashboard 3 is formed with a through hole 3a. ing. Further, a box-shaped bracket 4 is provided in the through hole 3a. The electronic device main body A is attached to the bracket 4 by the engaging means by inserting the electronic device main body A from the opening as shown by the arrow. That is, the engaged parts 10 formed by the convex parts 10a formed in the elastic part are formed to project outward on the left and right sides of the device body A, while the brackets 4 on the vehicle side are formed by the square holes. A portion 11 is provided, and the electronic device body A is fixedly attached to the bracket 4 by engaging the convex portion 10 a of the engaged portion 10 with the inner edge of the square hole of the engaging portion 11.

As shown in FIGS. 7 to 9, the electronic device main body A is provided with an escutcheon 1 and an outer escutcheon 2 on the front side, and a rear side thereof is covered with a case 8. A side plate 5 is attached to the side surfaces of the case 8 located on both sides of the outer escutcheon 2 with an attaching screw 9, and a handle rotating shaft 17 is provided on the front side of the side plate 5. A handle 7 is rotatably provided on the rotary shaft 17, and the handle cover 6 covers the handle 7. A handle stopper 15 is projectingly formed on the opposite side of the rotary shaft 17, and the turning range of the handle 7 is restricted by coming into contact with the side plate stopper 14 formed on the side plate 5. Further, the above-mentioned engaged portion 10 is formed on the side plate 5 so as to project therefrom.

Then, when the electronic device body A is detached from the vehicle-side bracket 4, as shown in FIG. 8, after the handle 7 is rotated upward about the rotation shaft 17, the pull-out operation is performed in the direction of the arrow. The engaged portion 10 of the electronic device body A is separated from the engaging portion 11 of the bracket 4 against elasticity. Thereafter, when the handle 7 is further pulled out, the electronic device body A 1 is detached from the bracket 4.

However, when the electronic device body A is disengaged from the bracket 4, the engagement between the engagement portion 11 of the bracket 4 and the engaged portion 10 of the electronic device body A must be released. The engagement force of is set to a strength that does not disengage from vibration of the vehicle. Since this engaging force is about 10 kg in some cases, there has been a problem that the user cannot pull out the electronic device main body A even if the user tries to pull it out. Further, the handle 7 and the rotary shaft 17 and the like also need to have the strength necessary for releasing the engaging force, which is inevitable because the handle 7 becomes large or the structural strength is increased. There was also a problem that the cost was high.

[0007]

[Problems to be solved by the device]

 The problem to be solved is that the engaging force between the vehicle-side bracket engaging part and the engaged part of the electronic device body is large, so even if the user tries to pull out the electronic device body from the bracket, a great deal of force is required. Is necessary and cannot be drawn out.

[0008]

[Means for Solving the Problems]

 The present invention has an engaged portion that removably engages with an engaging portion provided on a bracket of a car, and has a rotatably provided handle for pulling out for performing an operation of detaching from the engaging portion. In an in-vehicle electronic device, a pressing portion is extended in a direction opposite to the rotation axis of the handle, and when the handle is rotated from the storage position to the pull-out position, the pressing portion presses a part of the vehicle side. With the feature of being detached from the bracket, the purpose of making it possible to easily pull out the electronic device main body from the bracket of the car without requiring a large force is realized with a simple configuration.

[0009]

[Action]

 If the pressing part is extended in the opposite direction to the rotation axis of the handle, and when the handle is rotated from the storage position to the pull-out position, a part of the vehicle side is pressed by the pressing part to separate it from the bracket, Even if the engaged part of the electronic device body and the engaging part of the bracket are engaged with each other with a large engaging force, the engagement between the handle and the pressing part is released with a small force due to the action of the lever with the rotation axis of the handle as a fulcrum. At the same time, the main body of the electronic device is displaced forward, which facilitates the pull-out operation. In addition, the cost can be kept to a minimum because the number of parts does not increase because all that is required is a simple modification by simply extending the pressing portion on the handle.

[0010]

【Example】

 Hereinafter, the configuration of the present invention will be described in detail based on the embodiments shown in the drawings. The same reference numerals as those in FIGS. 6 to 9 denote the same parts, and detailed description thereof will be omitted. FIG. 1 shows an embodiment of an in-vehicle electronic device according to the present invention, which is different from the above-mentioned electronic device main body in that a pressing portion 21 is integrally extended in a direction opposite to a rotating shaft 17 of a handle 20, This is because when the handle 20 was rotated from the stored position to the pulled-out position, a part of the vehicle side was pressed by the pressing portion 21 so as to be separated from the bracket 4.

That is, the handle 20 has a pressing portion 21 linearly extending in the opposite direction to the handle 20 and a cam portion 21a formed at the tip. The dimension of the pressing portion 21 from the rotary shaft 17 to the cam portion 21a is set to be longer than the dimension from the rotary shaft 17 to the front end surface of the bracket 4, which is a part on the vehicle side. As shown in FIG. 1, the handle 20 always has a handle portion stored below the electronic device main body A. The pressing portion 21 is normally hidden inside the outer escutcheon 2 as shown in FIG. 1, and is housed upward. A rear side of the outer escutcheon 2 is opened so as to allow at least rotation of a pressing portion 21 described later, and a tip of the pressing portion 21 is formed to be projectable.

Now, when pulling out the electronic device main body A from the state where the electronic device main body A is mounted on the bracket 4 of FIG. 1, first, the handle 20 is moved from the stored position around the rotary shaft 17 as shown in FIG. Rotate to. By this rotation operation, the cam portion 21a at the tip of the pressing portion 21 comes into contact with the front end surface of the bracket 4 which is a part on the vehicle side. After that, when the handle 20 is further rotated, the pressing portion 21 is longer than the dimension up to the rotating shaft 17 and the bracket 4, so that the cam portion 21a tries to move the electronic device main body A to the left in the drawing. In this movement operation, the pressing portion 21 exerts a large force on the cam portion 21a by the action of the lever having the rotating shaft 17 as a fulcrum, and the electronic device main body A moves. Such a large force exceeds the engaging force between the engaging portion 11 of the bracket 4 and the engaged portion 10 of the electronic device body A, and as shown in FIG. 2, it engages against the elasticity of the engaged portion 10. Withdraw from part 11.

When the handle 20 is further rotated, the electronic device body A moves away from the vehicle-side bracket 4 as shown in FIG. 3, and the pressing portion 21 is attached to the side plate stopper 14 formed on the side plate 5. By the contact, the movement of the electronic device main body A is stopped and the rotation of the handle 20 is stopped. In such a state, the engagement of both the engaging portions has already been disengaged, and therefore by pulling the handle to the left in the drawing, the electronic device main body A is pulled out from the bracket 4 with a small force. On the other hand, when mounting the electronic device main body A on the bracket 4, it can be easily mounted by storing the handle 20 in the state of FIG. 1, pushing it into the bracket 4, and engaging both engaging portions. .

FIG. 4 shows another embodiment of the present invention, which is an example in which a rotatable ring member 22 is disposed on a pressing portion 21 extending to the handle 20. That is, a pin 23 is provided at the tip of the pressing portion 21, and the ring member 22 is rotatably arranged around the pin 23. As described above, when the ring member 22 is rotatably arranged at the tip of the pressing portion 21, the sliding resistance of the pressing portion 21 to the bracket 4 and the like is reduced as the handle 20 is rotated, and the electronic device main body is reduced. There is a feature that the operability when pulling out A is further improved.

Further, FIG. 5 shows another embodiment of the present invention, in which the tip end portion 24 of the pressing portion 21 extending to the handle 20 has a distance from the center of the rotating shaft 17 to the pulling direction of the handle 20. It shows an example formed in a long arc shape. If the tip end portion 24 of the pressing portion 21 is formed in a long arc shape in this manner, the handle 20 can be lifted with a smaller force. That is, the electronic device body can be pulled out with a smaller force.

The present invention is not limited to the above-mentioned embodiments, and the pressing portion may be integrally extended to the handle by a separate member, and various modifications can be made without departing from the gist of the present invention. It is possible.

[0017]

[Effect of device]

 As is clear from the above description, the in-vehicle electronic device of the present invention has the pressing portion extending in the opposite direction to the rotation axis of the handle, and when the handle is rotated from the storage position to the pull-out position, the vehicle is driven by the pressing portion. Since it is configured to press a part of the side to disengage from the bracket, even if the engaged part of the electronic device body and the engaging part of the bracket are engaged with a large engaging force, the rotation of the handle By the operation, the pressing portion can be disengaged with a small force due to the action of the lever, and the force required for the operation of pulling out the electronic device body is significantly reduced. In addition, since it is possible to simply modify the handle by simply extending the pressing portion, the number of parts does not increase, and the cost can be minimized.
