Description

Technical Field

[0001] The utility model relates to the technical field of vehicle accessories, in particular to an automatically controlled exterior rearview mirror. Background Art

[0002] The exterior rearview mirror is one of the important components of a vehicle. It is usually composed of a mirror surface, a shell, an adjustment mechanism, etc. It is installed on both sides of the vehicle's exterior to provide the driver with a rear and side view so that he can timely understand the surrounding traffic conditions. The mirror surface of the exterior rearview mirror is generally specially treated and has good reflective properties to ensure clear images. Its shell plays a role in protecting internal components and also needs to have certain impact resistance and weather resistance. The adjustment mechanism allows the driver to adjust the angle of the rearview mirror according to his needs, thereby improving driving safety and comfort.

[0003] Existing technologies include a utility model with a publication number of CN202641528U, which discloses an exterior rearview mirror. The patent adopts a twister, a mirror housing, a mirror surface and an exterior rearview mirror support. The mirror housing is connected to the exterior rearview mirror support through the twister and rotates with the twister as the axis. A support fixing column is provided on the mounting surface of the exterior rearview mirror support. The twister is a universal joint twister. After adopting the above structure, the original bracket shaft structure is adjusted to the current simple universal joint structure, which has a simple structure and is easy to operate. The material of the exterior rearview mirror is changed from the original die-cast aluminum to plastic, which reduces the weight of the exterior rearview mirror, reduces the cost, and solves the problem of complex twister structure and high cost.

[0004] When using exterior mirrors to observe the driving environment, the lenses of most exterior mirrors currently available on the market need to be manually adjusted by the driver. During the adjustment process, the driver needs to extend his hand to the twisting structure to operate. When the driver is driving alone and needs to adjust the exterior mirror lens on the passenger side, the driver needs to park the vehicle to the side of the road before performing the adjustment operation, which increases the difficulty of adjusting the exterior mirror on the passenger side. Utility Model Content

[0005] The purpose of the utility model is to solve the disadvantage in the prior art that when a driver is driving alone and needs to adjust the exterior rearview mirror lens on the passenger side, the driver needs to park the vehicle on the side of the road before performing the adjustment operation, which makes it more difficult to adjust the exterior rearview mirror on the passenger side. The utility model proposes an automatically controlled exterior rearview mirror.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: an automatically controlled exterior rearview mirror, comprising a shell and a lens, the lens being arranged inside the shell, an adjustment component being arranged inside the shell, the adjustment component comprising a mounting seat, the mounting seat being fixedly connected to the inner wall of the shell, the side surface of the mounting seat being fixedly connected to a guide frame, the arc surface of the guide frame being installed with an assembly frame, the arc surface of the assembly frame being fixedly connected with a positioning bolt, the positioning bolt being slidingly connected to the inner wall of the guide frame, the surface of the positioning bolt being threadedly connected with a locking sleeve, the side surface of the mounting seat being fixedly connected to an arc-shaped gear ring, the side of the assembly frame close to the arc-shaped gear ring being fixedly connected to a U-shaped frame, the inner wall of the U-shaped frame being rotatably connected to a worm, the worm being meshed with the tooth groove of the arc-shaped gear ring, the side surface of the U-shaped frame being fixedly connected to a servo motor, and the worm being bolted to the drive shaft of the servo motor.

[0007] Preferably, the positioning bolt passes through the inner circumference of the guide frame, and there are two positioning bolts. The two positioning bolts are symmetrically arranged about the assembly frame. The positioning bolts can cooperate with the guide frame to guide the moving direction of the assembly frame in a locked state.

[0008] Preferably, the locking sleeve contacts the inner circumference of the guide frame, and there are two locking sleeves, which are symmetrically arranged about the arc-shaped gear ring. The position of the positioning bolt can be limited by the locking sleeve to ensure that the positioning bolt is always located within the guide frame.

[0009] Preferably, there are two U-shaped frames, which are symmetrically arranged about the worm. The U-shaped frames can support and limit the position of the worm to ensure that the worm can engage with the arc-shaped gear ring in the working state.

[0010] Preferably, an assisting component is provided on the surface of the assembly frame, and the assisting component includes a needle-type cylinder. A limiting hole is provided on the surface of the assembly frame, and the needle-type cylinder is plugged into the inner wall of the limiting hole. The driving end of the needle-type cylinder is fixedly connected with a connecting block, and a circular hole is provided on the surface of the connecting block. The connecting block is located on the inner wall of the circular hole and is rotatably connected to the connecting frame. The lens is fixedly connected to the side surface of the connecting frame, and the connecting frame and the needle-type cylinder can be connected through the connecting block, thereby ensuring the linkage between the needle-type cylinder and the connecting frame.

[0011] Preferably, a restraining collar is fixedly connected to the inner wall of the assembly frame, and the restraining collar is sleeved with the surface of the needle cylinder. The restraining collar can limit the lower end of the needle cylinder to improve the stability of the needle cylinder.

[0012] Preferably, the side of the connecting block away from the needle cylinder is arc-shaped, and the side of the connecting frame close to the needle cylinder is arc-shaped. The lens and the connecting block can be connected through the connecting frame, so that the connecting block can lift the lens when pushed.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] The utility model discloses an adjusting component and an assisting component. When the angle of the lens needs to be adjusted, the switch of the servo motor is turned on, the servo motor is energized to drive the worm, the worm is meshed with the arc gear ring, and thus cooperates with the U-shaped frame to push the assembly frame. Under the action of the positioning bolt and the locking sleeve, the assembly frame moves along the guiding direction of the guide frame, thereby cooperating with the assisting component to drive the lens to adjust in the left and right directions. When the up and down angles of the lens need to be adjusted, the switch of the upper or lower pin-shaped cylinder is turned on as needed. When the lower pin-shaped cylinder is working, the pin-shaped cylinder pushes the connecting block, the connecting block pushes the connecting frame, and the connecting frame pushes the lower end of the lens. Then the lens rotates under the guidance of the upper connecting block and the connecting frame, so that the lower end of the lens rotates upward. When the lens needs to be adjusted downward, the upper pin-shaped cylinder is turned on. By providing the adjusting component and the assisting component, the lens adjustment of the rearview mirror can be performed by electrical equipment, thereby reducing the problem that the driver needs to stop and manually adjust the rearview mirror during driving, and further improving the automation level of the rearview mirror.
