Description

Technical Field

[0001] The present application relates to the technical field of a vehicle rearview mirror, and in particular to a vehicle rearview mirror adjustment device. Background Art

[0002] The rearview mirror is a car component that allows the driver to observe the position of vehicles and pedestrians behind the car while driving. The rearview mirror plays a key role in the safe driving of the car. Due to the different heights and sitting positions of different drivers, the observation position of the rearview mirror needs to be adjusted. When adjusting the rearview mirror, the driver of the rearview mirror needs to rotate the lens of the rearview mirror at multiple angles to achieve a state that is convenient for the driver to observe and maintain the adjusted position to ensure the stability of the car during driving.

[0003] The related technology discloses a driver, including a bowl-shaped base, a mirror floating plate disposed on the upper end of the base and adjustable within a certain angle range relative to the base, an arc-shaped rack for transmission when two mirrors are adjusted and symmetrically arranged between the base and the mirror floating plate, and a driving device for driving the arc-shaped rack to move. The lower end of the arc-shaped rack is supported and installed in the base, the upper end of the arc-shaped rack is hinged to the mirror floating plate, and the straight lines where the two hinge axes between the upper end of the arc-shaped rack and the mirror floating plate are located are perpendicular to each other. The driver also includes a holding mechanism, which includes a first holding member disposed on the mirror floating plate and a second holding member disposed on the upper end. The first holding member and the second holding member cooperate with each other. The first holding member mainly includes a fixing section for fixing to the mirror floating plate and an arc-shaped holding section for contacting the arc surface of the second holding member, and an elastic upper opening is formed between the fixing section and the arc-shaped holding section. The elastic upper opening can be used to deform the first holding member to maintain the stillness between the first holding member and the second holding member.

[0004] However, when the side of the first retaining member away from the opening is connected to the second retaining member, the friction between the first retaining member and the second retaining member is relatively small, and the stability of maintaining the lens is relatively poor.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-9 This application is described in further detail.

[0027] An embodiment of the present application discloses a vehicle rearview mirror adjustment device.

[0028] Embodiment 1: This embodiment discloses a vehicle rearview mirror adjustment device, referring to Figure 1 and Figure 2, comprising a base 1, a mirror floating plate 2 and two arc-shaped racks 3 installed between the mirror floating plate 2 and the base 1. The mirror floating plate 2 is used to install a lens. The mirror floating plate 2 on the base 1 adjusts the angle of the mirror floating plate 2 through the two arc-shaped racks 3, so that the lens installed on the mirror floating plate 2 can be adjusted to an angle suitable for the driver to observe. The mirror floating plate 2 comprises an annular portion 21 and a connecting portion 22. One side of the annular portion 21 used to connect the lens is a mounting surface 23. The annular portion 21 is annular in shape as a whole and the connecting portion 22 is arranged on a side away from the mounting surface 23. The base 1 is put into the mirror floating plate 2 from one side of the mounting surface 23. The connecting portion 22 extends to a side away from the mounting surface 23 and the inner surface of the connecting portion 22 is an arc-shaped surface. One end of the connecting portion 22 away from the mounting surface 23 gradually bends toward the center of the mirror floating plate 2. The outer wall of the base 1 is configured to be hemispherical. A plurality of connecting portions 22 are circumferentially arranged and a diameter of mounting holes 24 formed on the side of the connecting portion 22 away from the mounting surface 23 due to the circumferential arrangement is smaller than the radius of the base 1, so that a portion of the outer wall of the base 1 is exposed from under the connecting portion 22 of the mirror floating plate 2, and the other portion is on the inner side of the mirror floating plate. The material used for the connecting portion 22 is elastic, such as plastic or metal. The base 1 is provided with a pressure strip 4 inside the mirror floating plate 2, and both ends of the pressure strip 4 are connected to the inside of the annular portion 21. The middle part of the pressure strip 4 is used to apply a force to the middle part of the base 1 to press the connecting portion 22. Since the pressure strip 4 presses the base 1 and the connecting portion 22 against each other through extrusion, the end of the connecting portion 22 away from the annular portion 21 is deformed. In the process of adjusting the angle of the mirror floating plate 2 relative to the base 1, the position where the connecting portion 22 abuts against the spherical outer wall of the base 1 is the position where the connecting portion 22 is away from the annular portion 21, so that the mirror floating plate 2 has the same stability in any position after adjustment. Since the extrusion deformation of the connecting portion 22 can generate friction on the outer wall of the base 1, the mirror floating plate 2 can be stably connected to the base 1.

[0029] refer to Figure 1 and Figure 3The base 1 includes a base body 11 and an upper cover 12. The outer wall of the base body 11 is set to be hemispherical. The upper cover 12 is fixed at the opening of the base body 11 at a larger diameter position. The upper cover 12 can be fixedly connected to the base body 11 through a buckle structure, so that when assembling, the base body 11 and the upper cover 12 are first connected, and then the base 1 is connected to the mirror floating plate 2 through the pressure strip 4. Connecting columns 41 are integrally provided at both ends of the pressure strip 4. The connecting columns 41 are used to connect to the side wall of the annular portion 21. Since the total length of the pressure strip 4 and the connecting columns 41 is greater than the inner diameter of the annular portion 21, in order to connect the connecting columns 41 to the annular portion 21, a first mounting groove 211 needs to be opened on the inner wall of the annular portion 21. The first mounting groove 211 is set to be L-shaped. One end of the first mounting groove 211 extends to the mounting surface 23 of the annular portion 21, and the other end extends circumferentially on the inner wall of the annular portion 21. At the same time, a spherical connector 31 is also integrally provided at one end of the arc-shaped rack 3 for connecting the mirror floating plate 2, and the spherical connector 31 is used to connect to the inner wall of the annular portion 21. A second mounting groove 212 is provided on the inner wall of the annular portion 21, and the second mounting groove 212 is arranged in an L shape, and one end of the second mounting groove 212 extends to the mounting surface 23 of the annular portion 21, and the other end extends circumferentially on the inner wall of the annular portion 21, and the first mounting groove 211 and the second mounting groove 212 are arranged in the same direction clockwise or counterclockwise at one end of the circumferentially extending inner wall of the annular portion 21. The middle part of the pressure strip 4 rotates to the middle part of the upper cover 12, and the hinge axis of the pressure strip 4 and the upper cover 12 extends in the length direction of the pressure strip 4.

[0030] During installation, it is necessary to first assemble the arc-shaped rack 3 in the base 1 and expose the spherical connector 31, then assemble the pressure strip 4 to the upper cover 12, and then place the pressure strip 4 and the base 1 into the interior of the mirror floating plate 2, and at the same time align the connecting column 41 with the end of the first mounting groove 211 close to the mounting surface 23, and align the spherical connector 31 with the end of the second mounting groove 212 close to the mounting surface 23, squeeze the base 1, so that the connecting column 41 reaches the corner of the first mounting groove 211, and the spherical connector 31 reaches the corner of the second mounting groove 212, and rotate the base 1 along the circumferential extension direction of the first mounting groove 211 and the second mounting groove 212, so that the pressure strip 4 enters the first mounting groove 211 to the end away from the mounting surface 23, and the spherical connector 31 reaches the end of the second mounting groove 212 away from the mounting surface 23, thereby connecting the base 1 to the mirror floating plate 2.

[0031] refer to Figure 4A guide groove 111 for installing the arc-shaped rack 3 is provided inside the base 1, and the arc-shaped rack 3 rotates along the guide groove 111. A driver 5 is fixedly provided inside the base 1, and the driver 5 includes a driving motor 51, a reducer 52 and a driving gear 53. The driving motor 51 is fixed inside the base 1, and the reducer 52 is connected to the driving motor 51. One end of the reducer 52 is used to install the driving gear 53, and the driving gear 53 is meshed with the arc-shaped rack 3. The driving gear 53 is pressed on the inner side of the arc-shaped rack 3, so that the outer side of the arc-shaped rack 3 rotates along the guide groove 111 under the action of the driving gear 53, so that the arc-shaped rack 3 drives the mirror floating plate 2 to move.

[0032] refer to Figure 5 and Figure 6 A connecting sleeve 6 is provided in the middle of the base 1, and the center line of the connecting sleeve 6 coincides with the center line of the base 1. The interior of the connecting sleeve 6 is used to install the fixing bolts, and the upper end of the connecting sleeve 6 is used to squeeze the upper cover 12. An elastic sheet 7 is fixedly provided at the lower part of the base body 11, and the two ends of the elastic sheet 7 are connected to the base body 11. The elastic sheet 7 is a metal plate, and one end of the connecting sleeve 6 is used to abut against the elastic sheet 7, and the end of the fixing bolt will squeeze the connecting sleeve 6 in the direction of the elastic sheet 7 after being fixed by threaded connection, so that the connecting sleeve 6 squeezes the elastic sheet 7 to cause elastic deformation, and the elastic force of the elastic sheet 7 is transmitted to the fixing bolt through the connecting sleeve 6. When the fixing bolt is subjected to force in the axial direction, the loosening of the fixing bolt can be reduced. The elastic sheet 7 is provided with a plurality of holes from both ends to the middle, and the diameter of the holes is reduced successively, so as to improve the deformation capacity of the elastic sheet 7.

[0033] Embodiment 2: This embodiment discloses a vehicle rearview mirror adjustment device, referring to Figure 7 and Figure 8 , which is different from the first embodiment in that: an axial hole 213 and a ball hole 214 are provided on the inner wall of the annular portion 21, the axial hole 213 is used to insert the connecting column 41, the ball hole 214 is used to insert the spherical connector 31, and an opening 215 is formed on one side of the ball hole 214, and the opening 215 is set in a U-shape or a V-shape, so that the ball hole 214 is deformed at the position of the inner wall of the annular portion 21, and the opening side of the opening 215 is connected with the ball hole 214, so that when the spherical connector 31 is inserted into the ball hole 214, the connecting hole of the ball hole 214 can be elastically deformed under the action of the opening 215, and the inside of the ball hole 214 is a spherical surface, so that the spherical connector 31 is spherically hinged on the annular portion 21. The axial hole 213 is cylindrical. The axis of the shaft hole 213 is parallel to the length direction of the pressure strip 4. A guide hole 42 is opened at the end of the pressure strip 4. One end of the connecting column 41 is slidably connected in the guide hole 42, and a spring 8 is arranged inside the guide hole 42. One end of the spring 8 abuts against the bottom of the guide hole 42, and the other end abuts against the connecting column 41.

[0034] During installation, the base body 11 and the upper end of the base 1 can be installed separately. First, the base body 11 is placed inside the mirror floating plate 2, and then the arc rack 3 is pressed into the ball hole 214 and placed in the base body 11. Then the driver 5 in the base body 11 is installed to connect the driver 5 with the arc rack 3, and then the upper cover 12 is connected to the base body 11. Finally, the pressure strip 4 is connected to the upper cover 12, and at the same time, the upper cover 12 is squeezed, and the connecting column 41 is squeezed to contract the spring 8. When the connecting column 41 is opposite to the shaft hole 213, the connecting column 41 extends out and is inserted into the shaft hole 213 under the action of the spring 8.

[0035] A long groove 43 is also provided on the side of the pressure strip 4 away from the upper cover 12. The long groove 43 is located on the side walls at both ends of the pressure strip 4 and the length direction of the long groove 43 is the same as the arrangement direction of the spring 8. The long groove 43 is connected to the guide hole 42 when the pressure strip 4 is extended inside. The width of the long groove 43 is smaller than the diameter of the guide hole 42, so that the spring 8 located in the guide hole 42 is partially exposed in the long groove 43. When the pressure strip 4 needs to be disassembled, the two springs 8 are squeezed along the length direction of the long groove 43 by tweezers at the same time. After the spring 8 contracts, the connecting column 41 is disengaged from the shaft hole 213, so that the pressure strip 4 can be removed from the mirror floating plate 2, which is convenient for disassembly.

[0036] refer to Figure 8 and Fig. 9 A spherical hole 9 is provided on one side of each connecting portion 22 away from the annular portion 21. A sphere can be placed in the spherical hole 9. The sphere abuts against the outer wall of the seat body 11, so that the connection between the connecting portion 22 and the seat body 11 can be converted into a connection between a sphere and the seat body 11. Grease can be applied in the spherical hole 9 to reduce the wear of the connecting portion 22 or the seat body 11 caused by friction and reduce damage.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
