DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The present application embodiment discloses a rearview mirror lens driver. Figure 1 , Figure 2 , Figure 3 and Figure 4 A rearview mirror lens driver includes a base 1, a movable ring 2 and a connecting plate 3. The base 1 is a bowl-shaped structure as a whole, with a cavity arranged inside and a spherical surface arranged outside; the movable ring 2 is movably sleeved on the open end of the base 1, and the inner side surface of the movable ring 2 is arranged as a spherical surface adapted to the base 1, so that the movable ring 2 can deflect in any direction on the base 1 through the spherical surface, and one end of the movable ring 2 protrudes from the base 1; the connecting plate 3 is fixedly buckled on the end of the movable ring 2 protruding from the base 1, and the connecting plate 3 covers the open end of the base 1, and a rearview mirror lens is installed on the surface of the connecting plate 3 away from the base 1, so that the connecting plate 3 can drive the rearview mirror lens to deflect in any direction on the base 1 under the connection action of the movable ring 2. In order to realize the automatic yaw of the connecting plate 3 on the base 1, a driving component 5 for driving the yaw motion of the connecting plate 3 is arranged in the cavity of the base 1; the driving component 5 includes two motors 51, two gears 52 respectively connected to the output ends of the two motors 51, and an arc-shaped rack 53 meshing with the two gears 52 at the same time. The rack 53 is rotatably installed in the cavity of the base 1, and the two ends of the rack 53 are respectively fixedly connected to the two sides of the connecting plate 3, so that when the two motors 51 drive the two gears 52 to rotate at the same time, the two gears 52 drive the rack 53 to rotate in the cavity of the base 1, thereby driving the connecting plate 3 to perform yaw motion on the base 1.

[0033] To ensure that the connecting plate 3 can stably deflect on the base 1, refer to Figure 2 , Figure 3 , Figure 4and Figure 5 A support mechanism for supporting the connecting plate 3 is provided in the cavity of the base 1. The support mechanism supports the connecting plate 3 so that the inner side of the movable ring 2 can rotate in close contact with the outer surface of the base 1. The support mechanism includes a support tube 4 fixed in the cavity of the base 1 and a ball hinge assembly for ball-jointing the middle of the connecting plate 3 with one end of the support tube 4; a cover body 6 is fixed on the open end of the base 1 by screws, and the cover body 6 is located between the connecting plate 3 and the base 1. A first mounting hole 7 is formed through the center of the cover body 6, and a second mounting hole 8 is formed through the center of the connecting plate 3. One end of the support tube 4 is penetrated with the first mounting hole 7 and the second mounting hole 8 in sequence and fixedly connected with the center of the bottom of the base 1. The ball hinge assembly includes a supporting ring 9 fixed in the first mounting hole 7, a plug-in ring 10 fixed in the second mounting hole 8, and a pressure ring 11 fixedly sleeved on one end of the support tube 4. The supporting ring 9, the plug-in ring 10, and the pressure ring 11 are all arranged in a bowl-shaped structure, and both ends are open. The plug-in ring 10 is made of plastic material and has a certain deformation ability. In the process of installing the connecting plate 3 on the movable ring 2, the plug-in ring 10 in the second mounting hole 8 on the connecting plate 3 can be inserted between the pressure ring 11 and the supporting ring 9, and the plug-in ring 10 can be inserted between the pressure ring 11 and the supporting ring 9. The inner wall of the connecting ring 10 is stably fitted with the outer wall of the pressure ring 11, and the outer wall of the plug-in ring 10 is stably fitted with the inner wall of the supporting ring 9, so that the plug-in ring 10, the supporting ring 9 and the pressure ring 11 are combined to form a stable ball-hinged secondary structure. Under the joint limiting action of the pressure ring 11 and the supporting ring 9, the plug-in ring 10 can drive the connecting plate 3 to swing in any direction around one end of the support tube 4, and at the same time, it can also prevent the connecting plate 3 from driving the movable ring 2 as a whole to move toward the bottom of the base 1, causing the inner wall of the movable ring 2 to be unable to rotate tightly with the outer wall of the base 1.

[0034] Since the support tube 4 supports the connecting plate 3, the support tube 4 needs to be stably installed in the cavity of the base 1. Considering the convenience of production and processing, the support tube 4 is processed separately from the base 1, and then the support tube 4 is fixedly connected to the center of the cavity of the base 1. Figure 2 , Figure 3 and Figure 6 A card slot is provided at the center of the bottom of the base 1, and a positioning platform 12 is fixedly connected in the card slot. A positioning cylinder 13 is protruding from the middle of the positioning platform 12, and the positioning cylinder 13 and the positioning platform 12 are integrally formed; the end of the support cylinder 4 away from the pressure ring 11 is covered on the positioning cylinder 13 and abuts against the positioning platform 12, and a plug-in slot 14 for the support cylinder 4 to be plugged in is provided on the positioning platform 12. The inner diameter of the support cylinder 4 is the same as the outer diameter of the positioning cylinder 13, and the outer diameter of the support cylinder 4 is stably fitted with the side wall of the plug-in slot 14, so that the support cylinder 4 is not easy to deflect under the joint action of the positioning cylinder 13 and the plug-in slot 14, and can stably support the connecting plate 3.

[0035] In order to prevent the support tube 4 from axially jumping along its length direction, it is necessary to firmly press the support tube 4 against the positioning platform 12. Figure 2 , Figure 5 and Figure 6 , a pressing piece is provided on the cover body 6, so that when the cover body 6 is stably covered on the open end of the base 1, the pressing piece on the cover body 6 can stably press the support tube 4 into the plug-in slot 14. The pressing piece is set as a horn 15 fixed on the cover body 6, one end of the horn 15 is located in the first mounting hole 7 on the cover body 6, when the cover body 6 is covered on the base 1, the other end of the cover body 6 is located in the cavity of the base 1, and the large diameter of the horn 15 faces the direction of the connecting plate 3, and the small diameter faces the direction of the positioning platform 12. A convex block 16 is provided on the side wall of the support tube 4, when the cover body 6 is covered on the base 1, the end of the horn 15 is pressed against the convex block 16, so that the support tube 4 is stably positioned on the positioning platform 12. In order to further enhance the pressing effect of the horn 15 on the protrusion 16, a countersunk hole is penetrated through the cover body 6, and a fastening screw 17 is passed through the countersunk hole on the cover body 6. A threaded hole 18 adapted to the fastening screw 17 is opened on the base 1. Through the connection between the fastening screw 17 and the threaded hole 18, the cover body 6 can be stably installed on the base 1, thereby ensuring that the horn 15 can stably press the support tube 4 against the positioning platform 12 through the protrusion 16.

[0036] Considering the convenience of assembling the various components of the driver, refer to Figure 5 and Figure 6 The supporting ring 9 is fixed on the inner wall of the large-diameter end of the horn 15, and a retreat hole 19 corresponding to the protrusion 16 is opened on the side wall of the small-diameter end of the horn 15. The support tube 4 and the horn 15 are both configured as rotating bodies. When assembling the support tube 4 and the cover body 6, the support tube 4 can be rotated first so that the protrusion 16 on the support tube 4 is aligned with the retreat hole 19 on the horn 15; then the end of the support tube 4 with the protrusion 16 is successively penetrated through the supporting ring 9 and the horn 15, so that the protrusion 16 passes through the retreat hole 19; the support tube 4 is rotated again so that the protrusion 16 on the support tube 4 is misaligned with the retreat hole 19; then the support tube 4 is sleeved on the positioning tube 13, and the cover body 6 is covered on the base 1, and the cover body 6 is stably fixed on the base 1 by fastening screws 17. At this time, the small mouth end of the horn 15 on the cover body 6 can stably press the support tube 4 against the plug-in groove 14 on the positioning platform 12 through the protrusion 16, and at the same time, the pressure ring 11 on the support tube 4 is located in the supporting ring 9 and a gap is left between the inner wall of the supporting ring 9 and the outer wall of the pressure ring 11 for the plug-in ring 10 to be inserted.

[0037] After the base 1, the support tube 4 and the cover 6 are assembled, the connecting plate 3 can be installed. Figure 2When installing the connecting plate 3, first insert the plug ring 10 on the connecting plate 3 between the supporting ring 9 and the pressing ring 11, and then fix the connecting plate 3 with the movable ring 2 on the base 1 by screws. At this time, the inner wall of the plug ring 10 is tightly fitted with the outer wall of the pressing ring 11, and the outer wall of the plug ring 10 is tightly fitted with the inner wall of the supporting ring 9, so that the connecting plate 3 can be stably deflected in any direction on the base 1 under the drive of the driving component 5. Since the rearview mirror lens needs to be installed on the connecting plate 3, a plurality of reinforcing ribs 21 are integrally formed on the surface of the connecting plate 3 away from the base 1. The setting of the reinforcing ribs 21 can improve the strength of the connecting plate 3 to a certain extent, so that the rearview mirror lens can be stably installed on the connecting plate 3. A through hole 20 connected to the positioning tube 13 is also opened at the center of the bottom of the base 1. The mounting screws are passed through the support tube 4, the positioning tube 13 and the through hole 20 in sequence and then connected to the rearview mirror housing of the car. The heads of the mounting screws abut against the positioning tube 13, so that the driver with the rearview mirror lens can be quickly fixed on the rearview mirror housing of the car.

[0038] The implementation principle of a rearview mirror lens driver of the embodiment of the present application is as follows: first, the support tube 4 is rotated so that the protrusion 16 on the support tube 4 is aligned with the retreat hole 19 on the horn tube 15; then, the end of the support tube 4 with the protrusion 16 is passed through the supporting ring 9 and the horn tube 15 in sequence, so that the protrusion 16 passes through the retreat hole 19; the support tube 4 is rotated again so that the protrusion 16 on the support tube 4 is misaligned with the retreat hole 19; then, the support tube 4 is sleeved on the positioning tube 13, and the cover body 6 is covered on the base 1, and the cover body 6 is stably fixed on the base 1 by the fastening screws 17, at which time the small end of the horn tube 15 on the cover body 6 can pass through the protrusion 1 6 Stably press the support tube 4 against the plug-in groove 14 on the positioning platform 12, while the pressure ring 11 on the support tube 4 is located in the supporting ring 9 and a gap is left between the inner wall of the supporting ring 9 and the outer wall of the pressure ring 11 for the plug-in ring 10 to be inserted; then insert the plug-in ring 10 on the connecting plate 3 between the supporting ring 9 and the pressure ring 11, and finally fix the connecting plate 3 and the movable ring 2 on the base 1 with screws. At this time, the inner wall of the plug-in ring 10 is tightly fitted with the outer wall of the pressure ring 11, and the outer wall of the plug-in ring 10 is tightly fitted with the inner wall of the supporting ring 9. At the same time, the two ends of the rack 53 are also fixedly connected to the two sides of the connecting plate 3, thereby completing the assembly of the driver.

[0039] After the driver is assembled, the driver is fixed to the rearview mirror housing of the car by installing screws, and then the rearview mirror lens is fixedly installed on the connecting plate 3 of the driver. By starting the two motors 51, the two motors 51 simultaneously drive the two gears 52 to rotate, and the two gears 52 drive the rack 53 to rotate in the cavity of the base 1, thereby driving the connecting plate 3 to perform a yaw motion on the base 1, and completing the angle adjustment of the rearview mirror lens.
