Description

Technical Field

[0001] This utility model belongs to the field of automotive rearview mirror technology, and specifically relates to an automotive rearview mirror with an anti-collision structure. Background Technology

[0002] Car rearview mirrors are mirror devices installed on the exterior or interior of a vehicle to help drivers observe the situation behind and to the sides of the vehicle. They are crucial for driving safety, allowing drivers to be aware of their surroundings and avoid accidents. Car rearview mirrors are exposed to collisions with external objects during use. Traditional rearview mirrors have a certain degree of resistance to external forces, but they are still susceptible to damage from impacts, especially under significant external forces. Furthermore, rearview mirrors cannot quickly retract or rotate upon impact, particularly those with a unidirectional rotating structure. Under the force of a reverse impact, the mirror can twist and break. Additionally, the lack of a protective structure on the mirror casing allows it to directly contact and break upon impact.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a car rearview mirror with an anti-collision structure to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a car rearview mirror with an anti-collision structure, comprising: a rearview mirror assembly, wherein the rearview mirror assembly is provided with a rearview mirror main shell, and both the front and rear ends of the rearview mirror main shell are provided with a set of protective outer sleeves, the rearview mirror assembly is also provided with a rotating shaft for assisting rotation, a rearview mirror mounting seat is provided below the rotating shaft, and two sets of symmetrically arranged bidirectional torsion springs are provided in the rearview mirror mounting seat, and a limiting block for assisting in limiting and rotating storage is provided on the outside of the bidirectional torsion springs, and both the front and rear ends of the rotating shaft are provided with a set of protruding posts for cooperating with the limiting blocks to form a limiting position.

[0006] As a preferred embodiment, a set of fitting ring grooves for easy disassembly and assembly of the outer protective kit are provided at both the front and rear ends of the outer side of the rearview mirror main housing. The outer protective kit is provided with a fitting ring seat, and a protective ring is fixedly connected to the outer side of the fitting ring seat.

[0007] In a preferred embodiment, the fitting ring seat and the fitting ring groove are fitted together with an interference fit structure, and the outer protective kit is made of rubber material, so that the fitting ring seat and the fitting ring groove are fitted together, and the outer protective kit is installed on the outside of the rearview mirror main shell to provide collision protection.

[0008] In a preferred embodiment, the bidirectional torsion spring keeps the limiting block in the front-rear direction without external force. The rearview mirror mounting base is provided with a mounting base body, and a rotating hole is opened on the upper surface of the mounting base body. The rotating shaft is sleeved into the inner side of the rotating hole. The rearview mirror main shell is subjected to a large external force, causing the rotating shaft to rotate around the rotating hole and causing the protrusion to abut against the limiting block and rotate.

[0009] In a preferred embodiment, a connecting rod is fixedly connected to the right side of the rearview mirror main housing, and the connecting rod is fixedly connected to the rotating shaft. Arc-shaped grooves are provided on both the front and rear sides of the rearview mirror main housing, and a protective inflatable seat is provided inside the arc-shaped groove for protection after inflation.

[0010] In a preferred embodiment, air guide holes are provided on the inner sides of both the connecting rod and the rotating shaft, and the left end of the air guide hole is connected to both sets of protective inflatable seats.

[0011] In a preferred embodiment, an inner annular groove is provided on the inner side of the rotating hole, and an arc-shaped sliding groove is also provided on the inner side of the inner annular groove to assist the arc-shaped rotation of the inflatable seat. An arc-shaped slider is movably fitted inside the arc-shaped sliding groove.

[0012] In a preferred embodiment, an inflatable seat is fixedly connected to the inner side of the inner ring groove and the arc-shaped slider. The inflatable seat is a compressed air bag and an air guide pipe is fixedly connected to one end near the center of the mounting body. A connecting air groove is opened on the outer side of the rotating shaft and is connected to the air guide pipe. When the rearview mirror assembly encounters an external force, it rotates past the limit block and squeezes the inflatable seat, which introduces compressed air into the protective inflatable seat through the air guide pipe, thus forming an elastic protection between the rearview mirror assembly and the car.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are:

[0014] 1. By adding a rearview mirror assembly, a rearview mirror mounting base, and an outer protective kit, both sets of outer protective kits are fitted onto the outer side of the rearview mirror main shell for protection. When a large external force is encountered, the protruding post abuts against the limiting block and rotates, causing the bidirectional torsion spring to rotate and retract the rearview mirror assembly. After the rotating shaft rotates past the position of the limiting block, the limiting block is driven back to its original position under the action of the bidirectional torsion spring's rotational force, thereby improving the anti-collision performance.

[0015] 2. By adding a rearview mirror assembly and a rearview mirror mounting base, the rearview mirror assembly rotates past the limit block when it encounters external force, squeezing the air seat and introducing compressed air into the protective air seat through the air guide tube, which can form elastic protection between the rearview mirror assembly and the car.
