The vehicle-mounted radar housing is detachably installed on the fixing seat. The inner wall of the fixing seat is fixedly installed with a clamping and fixing mechanism, a pressing and fixing mechanism, and a driving mechanism. The clamping and fixing mechanism includes two linkage plates and two linkage rods. The two linkage plates are driven by the driving mechanism to move relative to or away from each other, and the two linkage plates are respectively sleeved on the rod arms of the two linkage rods. Through the cooperation of the above and other structures, the utility model has the advantages of being convenient for fixing the vehicle-mounted radar housing, having a better fixing effect, and the vehicle-mounted radar housing is not easy to detach, and solves the problem that in the traditional method, only the vehicle-mounted radar is clamped and fixed, and after long-term shaking, the vehicle-mounted radar will still gradually detach from the pressing plate, and thus the fixing effect is average.

[0003] However, the above mechanism adopts mechanisms such as connecting rods and springs. The number of components in the device is large, the structure is complex, it is easy to be damaged, and the cost is high, which is not conducive to the popularization and use of the product. Summary of the Utility Model

[0004] Aiming at the above problems, the purpose of the utility model is to provide a fixing mechanism for an automotive radar, so as to solve the problems of complex structure, easy damage, and high cost caused by the existing fixing mechanism for an automotive radar in order to achieve a clamping fixation for the vehicle-mounted radar.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a fixing mechanism for an automotive radar, including a vehicle-mounted radar housing, the vehicle-mounted radar housing is installed at one end of a connecting rod, a clamping groove is formed on the connecting rod, an elastic support plate is slidably sleeved on the outer side of the connecting rod and is clamped with a clamping and positioning plate. The elastic support plate includes an end plate, and an elastic plate is connected to one end of the end plate facing the clamping and positioning plate. The clamping and positioning plate includes a connecting plate, the connecting plate is arranged at one end of a sleeve, and clamping claws adapted to clamp the clamping groove are arranged on the inner wall of the sleeve.

[0006] The beneficial effect of the utility model is that the clamping claws and the clamping groove can be directly formed.

[0007] In order to stably snap the snap - positioning plate onto the connecting rod;

[0008] As a further improvement of the above - mentioned technical solution: The number of the claw is multiple, and they are arranged at equal intervals around the axis of the sleeve. The snap - groove is composed of multiple conical rings arranged at equal intervals.

[0009] The beneficial effect of this improvement is that multiple claws can be stably snapped into the groove between adjacent conical rings in the snap - groove, ensuring that the snap - positioning plate is stably snapped onto the connecting rod.

[0010] In order to ensure the one - way snap - connection effect of the snap - positioning plate;

[0011] As a further improvement of the above - mentioned technical solution: The bottom surface of the conical ring in the snap - groove is arranged towards the direction of the vehicle - mounted radar housing.

[0012] The beneficial effect of this improvement is that under the snap - connection and fixation of the claws, the snap - positioning plate can only move unidirectionally towards the vehicle - mounted radar housing, and is blocked by the snap - groove when moving in the reverse direction, thus ensuring the one - way snap - connection effect of the snap - positioning plate.

[0013] In order to ensure the structural strength of the snap - positioning plate;

[0014] As a further improvement of the above - mentioned technical solution: A reinforcing plate is connected between the connecting plate and the sleeve. The number of the reinforcing plates is multiple, and they are arranged at equal intervals around the axes of the connecting plate and the sleeve.

[0016] In order to effectively improve the stability of the snap - positioning plate snapped onto the connecting rod;

[0017] As a further improvement of the above - mentioned technical solution: The elastic plate is an elastic arc - shaped plate structure. The number of the elastic plates is multiple, and they are arranged at equal intervals around the axis of the end plate.

[0018] The beneficial effect of this improvement is that the elastic plate can be pressed against the connecting plate, making the claws stably snapped inside the snap - groove.

[0019] In order to avoid the vehicle - mounted radar housing and the elastic support plate from damaging the paint surface of the vehicle bumper when contacting it;

[0020] As a further improvement of the above - mentioned technical solution: Rubber buffer pads II and rubber buffer pads I are respectively arranged on the end faces of the end plate and the vehicle - mounted radar housing facing each other.

[0021] The beneficial effect of this improvement is that the rubber buffer pad I and the rubber buffer pad II play a role in buffering and protecting the paint surface of the vehicle bumper.

Detailed Embodiment

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description of this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.

[0029] Embodiment 1:

[0030] As Figure 1As shown in FIG. 4, an automotive radar fixing mechanism includes a vehicle-mounted radar housing 1, the vehicle-mounted radar housing 1 is installed at one end of a connecting rod 2, a clamping groove 21 is formed on the connecting rod 2, an elastic support plate 3 is slidably sleeved on the outer side of the connecting rod 2 and a clamping positioning plate 4 is clamped thereon. The elastic support plate 3 includes an end plate 31, and an elastic plate 33 is connected to one end of the end plate 31 facing the clamping positioning plate 4. The clamping positioning plate 4 includes a connecting plate 41, the connecting plate 41 is arranged at one end of a sleeve 42, a clamping claw 44 adapted to clamp the clamping groove 21 is arranged on the inner wall of the sleeve 42. The clamping claw 44 and the clamping groove 21 can be directly formed. After the clamping positioning plate 4 and the connecting rod 2 are slidably sleeved, they are clamped and matched with each other, and then with the elastic support of the elastic plate 33 integrally formed with the elastic support plate 3, the vehicle-mounted radar housing 1 can be installed quickly and stably. The number of the clamping claws 44 is multiple, and they are arranged at equal intervals around the axis of the sleeve 42. The clamping groove 21 is composed of multiple conical rings arranged at equal intervals. The multiple clamping claws 44 can be stably clamped in the groove between adjacent conical rings in the clamping groove 21, ensuring that the clamping positioning plate 4 is stably clamped on the connecting rod 2. The bottom surface of the conical ring in the clamping groove 21 is arranged towards the direction of the vehicle-mounted radar housing 1. Under the clamping and fixing of the clamping claws 44, the clamping positioning plate 4 can only move unidirectionally towards the direction of the vehicle-mounted radar housing 1, and is blocked by the clamping groove 21 when moving in the reverse direction, thus ensuring the unidirectional clamping effect of the clamping positioning plate 4. A reinforcing plate 43 is connected between the connecting plate 41 and the sleeve 42. The number of the reinforcing plates 43 is multiple, and they are arranged at equal intervals around the axes of the connecting plate 41 and the sleeve 42. The reinforcing plate 43 can effectively improve the connection strength between the connecting plate 41 and the sleeve 42. The elastic plate 33 is an elastic arc-shaped plate structure. The number of the elastic plates 33 is multiple, and they are arranged at equal intervals around the axis of the end plate 31. The elastic plate 33 can be pressed against the connecting plate 41, so that the clamping claws 44 are stably clamped inside the clamping groove 21. Rubber buffer pads II 32 and rubber buffer pads I 11 are respectively arranged on the end faces of the end plate 31 and the vehicle-mounted radar housing 1 facing each other. The rubber buffer pads I 11 and the rubber buffer pads II 32 play a role in buffering and protecting the paint surface of the vehicle bumper.

[0031] The working principle of this technical solution is as follows: Open a hole at the position to be installed, such as on the front and rear bumpers. Then, orient the vehicle-mounted radar housing 1 towards the detection direction, insert the connecting rod 2 into the hole, and then slidably fit the elastic support plate 3 onto the connecting rod 2 with the end plate 31 facing the vehicle-mounted radar housing 1. Next, fit the clamping and positioning plate 4 onto the connecting rod 2 with the connecting plate 41 facing the elastic support plate 3. When the clamping claw 44 moves to the position of the clamping groove 21, the clamping claw 44 repeatedly undergoes elastic deformation and releases potential energy to deform and reset, thereby being unidirectionally clamped in the clamping groove 21. After being squeezed by the clamping and positioning plate 4, the elastic plate 33 exerts an elastic thrust on the clamping and positioning plate 4, making the clamping claw 44 more firmly clamped in the groove of the clamping groove 21, so that the vehicle-mounted radar housing 1 can be stably installed on the bumper.
