As an important component of a car, the exterior rearview mirror is easy to operate, highly practical, and can enhance the aesthetics of the whole vehicle. The performance of the exterior rearview mirror is crucial for the driving experience of the whole vehicle. The exterior rearview mirror rotates within a certain angle range of the mirror surface to meet the driver's field of view requirements, and is divided into manual and electric adjustment. The lens of the exterior rearview mirror is divided into electric folding and manual folding, which is selected according to different vehicle configurations. Depending on the vehicle model, the exterior rearview mirror has different shapes and structures. Generally speaking, it has basic structures such as a mirror housing, a bracket, a lens, a support plate, a steering device, and a base plate. The exterior rearview mirror is fixed to the front door by a bracket, and the gasket plays a sealing role such as waterproofing and dustproofing between the bracket and the door. The steering device in the rearview mirror structure is mainly used to drive the lens to rotate, so as to change the angle of the lens, so that the driver can obtain road conditions information through the lens.

[0003] The steering device in the prior art can only drive the rearview mirror lens to rotate, and cannot facilitate the removal of the lens during the disassembly process. Its function is relatively single. Moreover, in order to improve the stability of the lens during installation, most lenses in the prior art are embedded in the mirror frame of the rearview mirror. Therefore, when removing the lens, tools are needed to pry the installation part of the two, and improper operation is likely to damage the lens and affect the normal use of the rearview mirror.

By providing the annular support plate 14, the cam 12 can be supported from the bottom;

[0029] Refer to the attached drawings of the specification Figures 1 - 3, a rearview mirror lens deflector in this embodiment, a mounting housing 2 is provided at the rear side of the lens mounting plate 1. The top end of the iron shaft 5 located at the top of the cam 12 is movably connected to the inner top end of the mounting housing 2 through a bearing, and the bottom end of the iron shaft 5 located at the bottom of the cam 12 is movably connected to the inner bottom end of the mounting housing 2 through a bearing. The cam 12, the first bevel gear 7, the connecting rod 6, the second bevel gear 8, and the micro positive and negative motor 9 are all arranged inside the mounting housing 2. A mounting bracket 22 is fixedly provided at the rear side of the micro positive and negative motor 9, and the rear side of the mounting bracket 22 is fixedly connected to the inner wall of the mounting housing 2. By providing the mounting housing 2, the structures installed inside the mounting housing 2 can be protected, and one end of the iron shaft 5 is connected to the inner wall of the mounting housing 2 through a bearing, which can also fix the position of the iron shaft 5. First short plates 23 are fixedly provided on both sides of the mounting housing 2. One side of the top end of the first short plate 23 away from the mounting housing 2 is fixedly provided with a first round rod 24. A second short plate 25 is provided at the outer end of the first round rod 24. A second round rod 26 is inserted into the end of the second short plate 25 away from the mounting housing 2. The bottom end of the second round rod 26 is fixedly provided with a third mounting plate 28. The front side of the third mounting plate 28 is fixedly connected to the rear side of the lens mounting plate 1. A rectangular through hole 27 is provided on the second short plate 25, and the width of the rectangular through hole 27 is consistent with the diameter of the first round rod 24. By using the first short plate 23, the second short plate 25, and the third mounting plate 28, the lens mounting plate 1 and the mounting housing 2 can be movably connected together, so as to facilitate the rotation of the lens mounting plate 1 on the front side of the mounting housing 2 to achieve the purpose of deflection.

[0030] The specific implementation scenario is as follows: During the use of the present invention, the lens needs to be first installed on the lens mounting plate 1, and then the present invention is installed in the mirror frame of the rearview mirror. When it is necessary to operate the lens for deflection, the driving mechanism can be started first, and the connecting rod 6 is driven to rotate by the driving mechanism. At this time, the electromagnet 11 is in the energized state, so the electromagnet 11 can adsorb one end of the iron shaft 5. Therefore, the iron shaft 5 can be driven to rotate during the rotation of the connecting rod 6. Then, the iron shaft 5 drives the steering gear 4 to rotate. During the rotation of the steering gear 4, the incomplete gear 3 is driven to rotate. During the rotation of the incomplete gear 3, the lens mounting plate 1 is driven to rotate, so that the lens can be driven to rotate by using the lens mounting plate 1 to achieve the purpose of deflecting the lens by using the lens mounting plate 1.

[0031] When it is necessary to extend the lens mounting plate 1 from inside the spectacle frame, first cut off the power supply of the electromagnet 11, so that the electromagnet 11 no longer adsorbs one end of the iron shaft 5. Therefore, when the driving mechanism drives the connecting rod 6 to rotate at this time, the connecting rod 6 will not drive the iron shaft 5 to rotate. At this time, energize the annular electromagnet 13 so that the annular electromagnet 13 can adsorb the cam 12. So at this time, when the connecting rod 6 rotates, it will drive the cam 12 to rotate. During the rotation of the cam 12, the longer end will be rotated to the front side, so that the cam 12 can be used to push the limit pulley 15 forward, and drive the rotating shaft 16 and the first mounting plate 17 forward through the limit pulley 15, and the first mounting plate 17 can be used to drive the lens mounting plate 1 forward, so that the lens mounting plate 1 can drive the lens forward, so as to be able to push the lens out of the spectacle frame, facilitating people to disassemble the lens from the lens mounting plate 1, avoiding damage to the spectacle frame or the lens. Moreover, when pushing the lens mounting plate 1 forward, it will also drive the third mounting plate 28, the second round rod 26 and the second short plate 25 forward at the same time. Since a rectangular through hole 27 is provided on the second short plate 25, it is convenient for the second short plate 25 to move forward.

[0032] Refer to the attached drawings of the specification Figures 4 - 6 As shown in the figure, for a rearview mirror lens deflector of this embodiment, the driving mechanism includes a first bevel gear 7, the first bevel gear 7 is fixedly arranged at the outer end of the connecting rod 6, a second bevel gear 8 is meshed behind the first bevel gear 7, a micro positive and negative motor 9 is arranged behind the second bevel gear 8, and the front end of the output shaft of the micro positive and negative motor 9 is fixedly connected to the rear side of the second bevel gear 8. By using the micro positive and negative motor 9, the second bevel gear 8 can be driven to rotate. Since the first bevel gear 7 and the second bevel gear 8 are meshed with each other, the second bevel gear 8 can drive the first bevel gear 7 to rotate during the rotation process, so that the first bevel gear 7 can be used to drive the connecting rod 6 to rotate, so as to achieve the purpose of driving the connecting rod 6. Springs 18 are arranged on both sides of the cam 12, rings 19 are fixedly arranged at both ends of the springs 18, a vertical rod 20 penetrates through the inside of the rings 19, and second mounting plates 21 are fixedly arranged at the top and bottom of the vertical rod 20. The front sides of the two second mounting plates 21 located in front of the springs 18 are fixedly connected to the rear side of the lens mounting plate 1, and the rear sides of the two second mounting plates 21 located behind the springs 18 are fixedly connected to the inner wall of the mounting shell 2. When the present invention pushes the lens mounting plate 1 out of the spectacle frame, the springs 18 will be stretched. When it is necessary to move the lens mounting plate 1 back into the spectacle frame, the elastic force of the stretched springs 18 can be used to drive the lens mounting plate 1 to reset.

[0033] Specific implementation scenario: When the lens mounting plate 1 is extended, it will drive the second mounting plate 21 connected to the lens mounting plate 1 to move forward. During the movement of the second mounting plate 21, it will drive the vertical rod 20 to move forward and also drive the ring 19 at its outer end to move forward during the movement. Thus, one end of the spring 18 can be stretched by the ring 19, causing the spring 18 to be elongated. When the lens mounting plate 1 needs to be installed in the frame, after the longer end of the cam 12 rotates into the installation housing 2, the spring 18 will pull the lens mounting plate 1 to move backward under the action of its own elastic force, thereby helping the lens mounting plate 1 to reset.

[0034] Refer to the attached instructions Figure 4 For a rearview mirror lens deflector of this embodiment, a bottom support plate 29 is fixedly provided at the bottom of the rear side of the lens mounting plate 1. The bottom support plate 29 is provided at the bottom of the incomplete gear 3. The installation housing 2 is provided on the top of the bottom support plate 29. A plurality of balls 30 are fixedly provided on the top of the bottom support plate 29. The tops of the plurality of balls 30 are in contact with the bottom of the installation housing 2. By providing the bottom support plate 29, the installation housing 2 can be supported from the bottom. Moreover, by providing a plurality of balls 30 on the top of the bottom support plate 29, the friction between the bottom support plate 29 and the installation housing 2 can also be reduced.

[0035] The specific implementation scenario is as follows: During the rotation or deflection of the lens mounting plate 1, the tops of the balls 30 are in sliding contact with the bottom of the installation housing 2, thereby reducing the friction between the bottom of the installation housing 2 and the bottom support plate 29 and facilitating the rotation of the lens mounting plate 1.

[0036] Refer to the attached instructions Figure 1 For a rearview mirror lens deflector of this embodiment, a lens slot 33 is provided at the middle position of the front side of the lens mounting plate 1. A rubber ring 34 is provided inside the lens slot 33. The rubber ring 34 is fixedly connected to the inside of the lens mounting plate 1. The lens slot 33 can be used to conveniently install the lens on the front side of the lens mounting plate 1. Moreover, by providing the rubber ring 34, the friction between the lens and the lens mounting plate 1 can be increased to prevent the lens from slipping. A plurality of anti-slip grooves 32 are provided on the front side of the lens mounting plate 1. The installation housing 2 is provided on the rear side of the lens mounting plate 1. The installation housing 2 is not in contact with the lens mounting plate 1. By providing the anti-slip grooves 32, the friction between the lens and the lens mounting plate 1 can be increased. Moreover, by leaving a gap between the installation housing 2 and the lens mounting plate 1, the lens mounting plate 1 can be conveniently rotated in front of the installation housing 2.

[0037] The specific implementation scenario is as follows: When installing the lens, only need to insert the clamping block at the rear side of the lens into the lens slot 33. After insertion, the rubber ring 34 will contact the clamping block, so as to increase the friction between the inside of the lens slot 33 and the clamping block, prevent the lens from falling off the lens mounting plate 1, and improve the stability of installation.

[0038] Although the present invention has been described in detail with general descriptions and specific embodiments above, based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
