[0036] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0037] Example 1

[0038] In a typical implementation of the present invention, Figure 1-Figure 11As shown, a rearview mirror is proposed, comprising: a rearview mirror body 1 and a radar assembly detachably mounted on the bottom end of the rearview mirror body 1. Since the radar assembly is mounted on the bottom end of the rearview mirror body 1, the radar assembly can be better protected, and the radar assembly will not extend to the side of the rearview mirror body 1 away from the vehicle body, thereby reducing the collision probability of the radar assembly during driving.

[0039] The upper and lower ends of the rearview mirror body 1 are connected to rearview mirror brackets 10. The rearview mirror body 1 is fixedly connected to the vehicle body through the rearview mirror brackets 10 at its upper and lower ends, so that the rearview mirror body 1 is installed on the vehicle body. The rearview mirror body 1 and the rearview mirror bracket 10 are movably connected, and the angle of the rearview mirror body 1 can be adjusted according to needs.

[0040] Specifically, the radar assembly is detachably mounted on the bottom of the rearview mirror bracket 10 located at the lower end of the rearview mirror body 1. The radar assembly includes a housing, a housing bracket 5, a radar bracket 6 and a radar 7. Fig.10 As shown, the cover shell bracket 5 is an L-shaped structure, and a plurality of mounting holes are opened on the cover shell bracket 5. The cover shell bracket 5 is detachably connected to the bottom of the rearview mirror bracket 10 at the lower end of the rearview mirror body 1 by self-tapping screws or bolts, and the cover shell is also detachably mounted on the middle cover shell bracket 5 by self-tapping screws or bolts, thereby realizing the connection between the cover shell and the rearview mirror body 1.

[0041] The housing is a split structure, including a radar cover 2 and a radar cover 4. Figure 5 As shown, the radome 4 is detachably mounted on the housing bracket 5 by self-tapping screws or bolts, and the radome cover 2 is buckled on the radome 4 and fixed by the clamping structure 9 (as shown in FIG. Figure 8 As shown), the card structure 9 includes a card column and a plug connector that can be inserted and connected in the card column. In this embodiment, the card column is fixedly arranged on the radome 4, and the plug connector is fixedly arranged on the radome cover 2, so that the card connection and fixation are achieved through the cooperation of the plug connector and the card column. It can be understood that in other embodiments, the plug connector can also be fixedly arranged on the radome 4, and the card column is fixedly arranged on the radome cover 2. The specific setting positions of the card column and the plug connector can be determined according to actual design requirements, and no excessive restrictions are made here.

The radar bracket 6 is arranged in the radar cover 4 for the installation of the radar 7, so that the radar 7 is protected by the cover composed of the radar cover 4 and the radar cover 2. The strength of the radar cover 4 and the radar cover 2 is lower than the strength of the rearview mirror body 1 and the rearview mirror bracket 10. Therefore, when a collision occurs, the radar cover 4 and the radar cover 2 can be damaged before the rearview mirror body 1 and the rearview mirror bracket 10. During maintenance, the damaged radar cover 4 and radar cover 2 can be replaced without replacing the rearview mirror body 1 and the rearview mirror bracket 10, which facilitates maintenance and reduces maintenance costs.

[0043] The strength of the cover bracket 5 is also lower than that of the rearview mirror body 1 and the rearview mirror bracket 10, so that it can be damaged before the rearview mirror body 1 and the rearview mirror bracket 10 when scratched. The cover bracket 5 and the cover can be replaced separately, which greatly improves the maintenance performance.

[0044] like Fig.11 As shown, the radar bracket 6 includes a supporting portion 61 and a clamping portion. There are several clamping portions, which are evenly distributed on the surrounding side of the supporting portion 61. The supporting portion 61 has a certain elastic deformation ability and can play a role of buffer support for supporting the radar 7. The clamping portion includes a supporting limit column 62 and a clamping claw 63. There are two clamping claws 63 and they are relatively arranged on both sides of the supporting limit column 62. The supporting limit column 62 is used to be inserted into the through hole of the radar 7 to support and limit the position of the radar 7. The clamping claws 63 are used to clamp on both sides of the through hole of the radar 7 to prevent the radar 7 from escaping from the supporting limit column 62.

[0045] Specifically, the support and limit column 62 is a variable diameter structure, the head diameter of the support and limit column 62 is smaller than its root, and the root diameter of the support and limit column 62 is larger than the diameter of the through hole of the radar 7. A number of connecting plates are fixedly provided on the peripheral side of the radar 7, and through holes are opened on the connecting plates for the insertion of the support and limit column 62. During actual installation, the connecting plates are clamped between the two claws 63 to limit the position of the connecting plates.

[0046] By setting the radar bracket 6, the radar 7 can be quickly disassembled and assembled without using bolts or other structures to fix the radar 7, which facilitates the installation and maintenance of the radar 7.

[0047] The radar 7 is connected to the vehicle computer through the radar harness 8. Figure 3 , Fig. 9As shown, the radar harness 8 is arranged in the rearview mirror bracket 10, and the radar harness 8 is covered by the cooperation between the rearview mirror bracket 10 and the cover plate, which not only protects the radar harness 8 but also improves the aesthetics. One end of the radar harness 8 is connected to the radar 7 in the cover, and the other end passes through the fixed end of the rearview mirror bracket 10 and is connected to the vehicle computer. A decorative cover 3 is installed at the fixed end of the rearview mirror bracket 10 (fixed to the vehicle body) to cover the radar harness 8 and fixing bolts, etc. through the decorative cover 3, further improving the aesthetics. The other end of the radar harness 8 is covered and protected by a cover.
