[0026] There are multiple radars on the car, which can generally be installed on the frame or bumper. Before installing the radar, the frame or bumper needs to be punched and painted. The frame or bumper may have burrs, paint accumulation around the holes causing increased thickness around the holes, or plastic deformation causing manufacturing defects. In the prior art, the radar can be connected to the vehicle through a bracket. The matching surface between the bracket and the vehicle's frame or bumper will affect the assembly accuracy of the radar due to the above defects. Therefore, how to solve the assembly error between the vehicle and the bracket is a technical problem that needs to be solved urgently.

[0027] In order to solve the above technical problems, refer to Figure 1 and Figure 2 As shown, the present application provides a vehicle radar device 1, including a main bracket 10, the main bracket 10 is formed with a first mounting hole 11; a sub-bracket 20, the sub-bracket 20 includes a mounting portion 21 and a connecting portion 22, the mounting portion 21 is protruding from the connecting portion 22, the mounting portion 21 is arranged in the first mounting hole 11, the connecting portion 22 is against one side of the main bracket 10, the connecting portion 22 forms a groove structure 221, the groove opening 2211 of the groove structure 221 faces the main bracket 10, and a part of the main bracket 10 facing the first mounting hole 11 is located in the groove structure 221; a radar 30, the radar 30 is arranged on the mounting portion 21.

[0028] The main bracket 10 may be a frame or a bumper of a vehicle, etc., and the sub-bracket 20 is arranged on the main bracket 10, and the mounting portion 21 of the sub-bracket 20 is arranged on the first mounting hole 11, and the connecting portion 22 is pressed against one side of the bumper. A groove structure 221 is formed on the connecting portion 22, and the notch 2211 of the groove structure 221 faces the main bracket 10, and the part of the main bracket 10 facing the first mounting hole 11 is located in the groove structure 221. The burrs generated by molding the first mounting hole 11 on the main bracket 10, the paint thickness increased around the first mounting hole 11 by spraying the main bracket 10 with paint, or the dimensional tolerance caused by the deformation of the statue will be placed therein due to the setting of the groove structure 221. When the sub-bracket 20 is matched with the main bracket 10, the burrs, the paint thickness and the dimensional tolerance are absorbed by the groove structure 221, and the assembly error between the main bracket 10 and the sub-bracket 20 is reduced, thereby improving the assembly quality of the radar 30.

[0029] In some embodiments, the main bracket 10 can be a vehicle frame and a bumper. Generally speaking, the front bumper and the rear bumper of the vehicle are both provided with a plurality of vehicle radars 30, and it is necessary to open a plurality of first mounting holes 11 for the vehicle radars 30 on the frame and the bumper. The first mounting holes 11 can be formed by cutting, stamping and other processes, and the forming process is not specifically limited here. After stamping, the frame or the bumper is spray-painted to obtain a body-in-white.

[0030] In some embodiments, the groove structure 221 may be a straight groove structure or an arc-shaped groove structure. A fillet may be provided between the bottom and the side wall of the groove structure 221 to reduce the stress of the groove structure 221 .

[0031] In some embodiments, reference Figure 1 As shown, the width of the groove structure 221 along the first direction X1 is between 1.5 mm and 2.5 mm, and the depth of the groove structure 221 along the second direction X2 is between 0.5 mm and 1.5 mm, and the first direction X1 and the second direction X2 are perpendicular. Figure 1 The first direction X1 is the horizontal direction, and the second direction X2 is the vertical direction. The width of the groove structure 221 in the first direction X1 can be 1.5mm, 2.0mm, or 2.5mm, and the depth of the groove structure 221 in the second direction X2 can be 0.5mm, 1.0mm, or 1.5mm. The above data are determined based on the size of the burrs that may be generated by punching, the thickness of the paint surface for muscle enhancement by spray painting, or the size of plastic deformation. Generally speaking, the size of the vehicle's bumper and frame will not exceed the above range due to the above defects, which can effectively reduce assembly errors.

[0032] In some embodiments, reference Figure 1 As shown, the mounting portion 21 is formed with a second mounting hole 211, and the radar 30 is disposed in the second mounting hole 211. The second mounting hole 211 can be formed by cutting, stamping, and the like, and the forming process is not specifically limited here. The second mounting hole 211 corresponds to the shape of the radar 30, so that the radar 30 can be mounted in the second mounting hole 211, thereby improving the mounting accuracy of the radar 30.

[0033] In some embodiments, reference Figure 1 As shown, along the axial direction, the diameter of one side of the radar 30 is the first diameter D1, and the diameter of the other side of the radar 30 is the second diameter D2. The first diameter D1 is smaller than the second diameter D2 to form a step surface 31. The sub-bracket 20 includes a clamping member, which is arranged on the side wall of the second mounting hole 211 and extends inwardly, and the clamping member is arranged on the step surface 31. The radar 30 is generally circular, the first mounting hole 11 and the second mounting hole 211 are coaxially arranged, and the axial direction is the extension direction of the axis of the first mounting hole 11 and the second mounting hole 211. The side of the radar 30 facing the outside of the vehicle body has a first diameter D1, and the side of the radar 30 facing the inside of the vehicle body has a second diameter D2, that is, the diameter of the side of the radar 30 facing the outside of the vehicle body is smaller than the diameter of the side facing the inside of the vehicle body. Such a design is mainly determined by the structural characteristics of the radar 30 itself. The clamping member on the sub-bracket 20 can better adapt to the characteristics of the radar 30, so as to have a better fixing effect on the radar 30, thereby increasing the installation stability of the radar 30.

[0034] In some embodiments, reference Figure 2As shown, the radar 30 is provided with a buckle 32, the sub-bracket 20 is provided with a clamping hole 23, the radar 30 is arranged in the second mounting hole 211, and the buckle 32 is located in the clamping hole 23. The buckle 32 is generally arranged on the peripheral side of the radar 30, and the clamping hole 23 is generally arranged on the side wall of the second mounting hole 211. The clamping hole 23 can be selected to penetrate the side wall of the mounting portion 21 according to actual needs. The buckle 32 and the clamping hole 23 are arranged correspondingly, so that the radar 30 can be more stably installed in the second mounting hole 211 to avoid movement in the axial direction and rotation in the radial direction.

[0035] In some embodiments, reference Figure 2 As shown, a notch 212 is provided on the peripheral side of the mounting portion 21, and the radar 30 includes a plug-in port 33, which is extended in the radial direction and is arranged at the notch 212. The notch 212 penetrates part of the mounting portion 21 to form an open space in the extension direction of the plug-in port 33, so that the plug-in port 33 can be extended in the radial direction, and the installation space of the radar 30 can be saved by using an external plug.

[0036] In some embodiments, reference Figure 2 As shown, the sub-bracket 20 is provided with a welding portion 24, and the welding portion 24 is used for welding and fixing the sub-bracket 20 and the main bracket 10. Part of the welding portion 24 is recessed on the connecting portion 22, and the thickness of the welding portion 24 in the first direction X1 is less than the connecting portion 22. Part of the main bracket 10 and the sub-bracket 20 are metal brackets, and the welding portion 24 can be filled with solder. The main bracket 10 and the sub-bracket 20 are connected by welding at the welding portion 24. In order to ensure good welding performance between the welding surface of the main bracket 10 and the welding surface of the sub-bracket 20, it is necessary to thin the thickness of the welding portion 24, and the thinning to form a recessed area can be filled with solder. In addition, such a design can turn the welding portion 24 toward the inside of the vehicle body, and also reduce the risk of damaging the external structure of the vehicle body. Filling the recessed area with solder can serve as a reference during welding, ensuring that the welding areas of different white bodies are more consistent.

[0037] The present application also provides a vehicle, referring to Figure 3 As shown, it includes a bumper 2 and a vehicle radar device 1, the bumper 2 is a main bracket 10, and the vehicle radar device 1 is arranged on the bumper 2 for monitoring the driving state of the vehicle.
