[0034] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0035] like Figure 1-Figure 3 As shown, an embodiment of the utility model provides a vehicle rearview mirror assembly, which is arranged on the cab of an engineering vehicle.

[0036] The vehicle rearview mirror assembly comprises a bracket 1, a connecting component 2 and a rearview mirror 3. The rearview mirror 3 is arranged at one end of the bracket 1 along a first direction. The other end of the bracket 1 along the first direction is connected to the cab through the connecting component 2. The bracket 1 has a working position and an avoidance position. When the bracket 1 is in the avoidance position, the distance between the rearview mirror 3 and the cab is smaller than the distance between the rearview mirror 3 and the cab when the bracket 1 is in the working position. The connecting component 2 can rotate and switch the bracket 1 between the working position and the avoidance position, and the connecting component 2 can also fix the bracket 1 in the working position and the avoidance position, so that the vehicle rearview mirror assembly is maintained in the working state and the avoidance state. That is, when the engineering vehicle is traveling on a normal road, the bracket 1 is in the working position, and the connecting component 2 can fasten the bracket 1 and the cab to keep the vehicle rearview mirror assembly in a working state; when the engineering vehicle is traveling on a narrow road, the connecting component 2 can rotate the bracket 1 to a certain angle (for example, 90°), and the bracket 1 is in the avoidance position, and the connecting component 2 can fasten the bracket 1 and the cab to keep the vehicle rearview mirror assembly in an avoidance state to pass through the narrow road.

[0037] The vehicle rearview mirror assembly enables the bracket 1 to be rotated and switched between the working position and the avoidance position through the connecting component 2. The vehicle rearview mirror assembly can be switched between the working state and the avoidance state without disassembly, thereby avoiding disassembly and assembly operations and improving work efficiency.

[0038] Specifically, a mounting frame 100 is provided on the cab, a fixing plate 121 is provided at the other end of the bracket 1 along the first direction, and the connecting assembly 2 is connected to the mounting frame 100 and the fixing plate 121 .

[0039] Optionally, a plurality of fixing plates 121 are provided at the other end of the bracket 1 along the first direction, and the plurality of fixing plates 121 are arranged at intervals along the second direction. In the present embodiment, the first direction is a horizontal direction, and the second direction is a vertical direction. Mounting frames 100 corresponding to the fixing plates 121 are provided at positions corresponding to the engineering vehicle and the vehicle rearview mirror assembly, and each fixing plate 121 is rotatably connected to the mounting frame 100 via a connecting component 2.

[0040] In this embodiment, the other end of the bracket 1 along the first direction is provided with two fixed plates 121 spaced apart along the second direction, and the connection assembly 2 includes a first fixed connection assembly 21 and an elastic connection assembly 22. One fixed plate 121 is connected to the corresponding mounting frame 100 through the first fixed connection assembly 21, and the other fixed plate 121 is elastically connected to the corresponding mounting frame 100 through the elastic connection assembly 22 and can rotate with each other. When the bracket 1 rotates, the structure only needs to loosen the first fixed connection assembly 21, and then rotate the bracket 1 to overcome the elastic force of the elastic connection assembly 22 to realize the rotation of the bracket 1. The first fixed connection assembly 21 realizes the fixed connection between one fixed plate 121 and the corresponding mounting frame 100, and the elastic connection assembly 22 realizes the elastic connection between the other fixed plate 121 and the corresponding mounting frame 100. While ensuring the stable connection between the bracket 1 and the mounting frame 100, the convenience of operation is further improved.

[0041] Of course, a plurality of fixing plates 121 spaced apart along the second direction may be provided at the other end of the bracket 1 along the first direction, the number of the fixing plates 121 may be more than two, at least one of the plurality of fixing plates 121 is connected to the corresponding mounting frame 100 via the first fixed connection component 21, and the remaining fixing plates 121 are elastically connected to the corresponding mounting frames 100 via the elastic connection components 22; or the plurality of fixing plates 121 may also be rotatably connected to the corresponding mounting frames 100 via the fixed connection components 2; or only one fixing plate 121 is provided, and one fixing plate 121 is connected to the mounting frame 100 via the fixed connection component 2.

[0042] Furthermore, if Figure 2-Figure 3 As shown, the fixing plate 121 is elastically connected to the corresponding mounting frame 100 through the connecting frame 4. The connecting frame 4 includes a connecting plate 41 and a supporting connecting member 42 which are connected to each other. The connecting plate 41 is fixedly connected to the corresponding mounting frame 100. The supporting connecting member 42 is used to be elastically connected to the corresponding fixing plate 121 through the elastic connecting component 22. The structure is made more reasonable by setting the connecting frame 4.

When the supporting connector 42 is elastically connected to the corresponding fixing plate 121, the limiting portion 1211 can be limited in the limiting groove 4221. In this structure, the limiting portion 1211 is limited in the limiting groove 4221, so that the vehicle rearview mirror assembly is more stable when in a working state. When the fixed connection component 2 is loose, the limiting portion 1211 can escape from the limiting groove 4221 after the rotating bracket 1 overcomes the elastic force of the elastic connection component 22.

[0044] The limiting portion 1211 includes two limiting cylinders that are spaced apart. The outer circumference of the limiting cylinder is welded to the corresponding fixing plate 121 . The longitudinal section of the limiting groove 4221 is arc-shaped. The two limiting cylinders can be limited in the limiting groove 4221 .

The boss 422 is arranged on the side of the supporting channel steel 421 facing the fixed plate 121 , and the limiting groove 4221 is arranged on the boss 422 .

[0046] Optionally, the elastic connection assembly 22 includes a first bolt 221, a first nut 222 and an elastic member 223, the first bolt 221 is passed through the corresponding fixed plate 121 and the support connection member 42, and at the same time the first bolt 221 is passed through the boss 422 and is located between two limiting cylinders, the first nut 222 is screwed on the first bolt 221, the elastic member 223 is sleeved on the first bolt 221, and the two ends of the elastic member 223 elastically abut the support connection member 42 and the first nut 222 respectively, that is, the elastic member 223 abuts the support connection member 42, so that the support connection member 42 presses the corresponding fixed plate 121 to achieve an elastic connection between the two. The structure is simple and the design cost is low.

[0047] Optionally, the elastic member 223 may be a compression spring or a disc spring.

[0048] The first fixed connection assembly 21 includes a second bolt 211 and a second nut 212. The second bolt 211 is passed through the corresponding fixed plate 121 and the mounting frame 100. The second nut 212 is screwed to the second bolt 211 to fix the fixed plate 121 and the mounting frame 100. This structure makes the loosening operation of the fixed connection assembly 2 more convenient.
