DETAILED DESCRIPTION

[0030] 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.

[0031] The embodiment of the present application discloses a rearview mirror lens driver with a waterproof structure. Figure 1 , Figure 2 , Figure 3 and Figure 4 A rearview mirror lens driver with a waterproof structure includes a base 2, a movable ring 4 and a connecting plate 1. The connecting plate 1 is used to install the rearview mirror lens. The base 2 is arranged at intervals on the side of the connecting plate 1 away from the rearview mirror lens. A cavity is provided on the surface of the base 2 close to the connecting plate 1. A driving component 3 for driving the connecting plate 1 to adjust the angle is provided in the cavity. The driving component 3 includes two motors 31, two gears 32 connected to the output ends of the two motors 31 respectively, and an arc-shaped rack 33 that meshes with the two gears 32 at the same time. The rack 33 is assembled in the cavity of the base 2 through an arc-shaped guide rail structure. The two ends of the rack 33 extend out of the cavity of the base 2 and are fixedly connected to the two sides of the connecting plate 1 respectively, so that when the two motors 31 drive the two gears 32 to rotate at the same time, the two gears 32 drive the rack 33 to slide in the cavity of the base 2, thereby driving the connecting plate 1 to perform a yaw motion on the base 2. The movable ring 4 is located between the connecting plate 1 and the base 2. One end of the movable ring 4 is sealingly connected to the base 2, so that the movable ring 4 is connected to the cavity on the base 2. The sealing cover of the connecting plate 1 is arranged on the other end of the movable ring 4. The movable ring 4 can adapt to the angle adjustment of the connecting plate 1 on the base 2, so that no matter what angle the connecting plate 1 is adjusted to, the connecting plate 1 can be arranged at the open end of the cavity of the base 2 through the sealing cover of the movable ring 4, effectively preventing water vapor from entering the cavity of the base 2 and corroding the drive component 3.

[0032] In order to make the movable ring 4 adapt to the angle adjustment of the connecting plate 1, in the embodiment of the present application, the movable ring 4 is connected to the base 2 by a ball hinge. Figure 1 , Figure 2 , Figure 3 and Figure 4The base 2 is a bowl-shaped structure as a whole, and the outer surface of its open end is set to a spherical surface; the movable ring 4 is movably sleeved on the open end of the base 2, and the inner side surface of the movable ring 4 is set to a spherical surface adapted to the base 2, so that the movable ring 4 can swing in any direction on the base 2 through the spherical surface, and at the same time, one end of the movable ring 4 protrudes from the open end of the base 2; the connecting plate 1 is fixedly buckled on the end of the movable ring 4 protruding from the base 2, and the connecting plate 1 covers the open end of the base 2, and the rearview mirror lens is installed on the surface of the connecting plate 1 away from the base 2, so that the connecting plate 1 can drive the rearview mirror lens to swing in any direction on the base 2 under the connection action of the movable ring 4.

[0033] In other embodiments, the movable ring 4 can be configured as a flexible accordion cover or an elastic cover with extensibility, and the base 2 and the connecting plate 1 are respectively sealed and connected to the two ends of the accordion cover, so that the accordion cover can not only stably seal the gap between the base 2 and the connecting plate 1, but also can adapt to the angle adjustment of the connecting plate 1 on the base 2.

[0034] In order to enable the connecting plate 1 to be quickly and tightly mounted on one end of the movable ring 4, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A snap ring 5 is protrudingly provided on the surface of the connecting plate 1 away from the side of the rearview mirror lens. The snap ring 5 is integrally formed with the connecting plate 1. The snap ring 5 is sleeved and adapted to the end of the movable ring 4. The movable ring 4 is provided with a snap-on structure for snapping and connecting with the snap ring 5. Through the snap-on structure, the snap ring 5 can be stably sleeved on the end of the movable ring 4, so that the connecting plate 1 can seal and cover one end of the movable ring 4. The snap-on structure is specifically configured as a plurality of snap blocks 6 on the outer wall of the movable ring 4, and a snap groove 7 that is snap-on and adapted to the snap block 6 is provided on the inner wall of the snap ring 5. The snap ring 5 is made of plastic material and has a certain deformation ability. The surface of the snap block 6 on one side close to the connecting plate 1 is configured as an inclined surface, and the surface of the side away from the connecting plate 1 is perpendicular to the outer wall of the movable ring 4. When it is necessary to buckle the connecting plate 1 on one end of the movable ring 4, it is only necessary to pre-set the snap ring 5 on one end of the movable ring 4, and then adjust the relative positions of the movable ring 4 and the snap ring 5 so that the clamping block 6 is aligned with the clamping groove 7, and then push the connecting plate 1 toward the movable ring 4 with force so that the clamping block 6 on the movable ring 4 is clamped into the clamping groove 7 on the inner wall of the snap ring 5; in the process of the clamping block 6 being clamped into the clamping groove 7, the snap ring 5 first contacts with the inclined surface of the clamping block 6, and as the connecting plate 1 continues to move toward the movable ring 4, the snap ring 5 adaptively deforms until the clamping block 6 enters the clamping groove 7 and then returns to its original state. At this time, under the clamping action of the clamping block 6 and the clamping groove 7, the snap ring 5 is stably sleeved on one end of the movable ring 4, thereby realizing a stable sealing connection between the connecting plate 1 and one end of the movable ring 4.

[0035] Since the clamping groove 7 is located on the inner wall of the clamping ring 5, and the clamping ring 5 is sleeved and adapted with the end of the movable ring 4, in order to ensure that when the connecting plate 1 is pushed toward the movable ring 4, the clamping groove 7 and the clamping block 6 are in an aligned state, Figure 1 , Figure 2 , Figure 3 and Figure 4 , a positioning ring 8 is fixedly sleeved on the movable ring 4, and an alignment hole 9 is opened on the positioning ring 8. An alignment block 10 adapted to the alignment hole 9 is arranged on the end of the snap ring 5 away from the connecting plate 1. When the alignment block 10 is aligned with the alignment block 10, it means that the clamping groove 7 on the current snap ring 5 is aligned with the clamping block 6 on the movable ring 4. At this time, the connecting plate 1 can be pushed forcefully toward the movable ring 4, so that the clamping block 6 is smoothly inserted into the clamping groove 7. When the clamping block 6 is inserted into the clamping groove 7, the alignment block 10 is also aligned and inserted into the alignment hole 9. In order to quickly adjust the alignment block 10 to align with the alignment hole 9, a rotating block 11 is protruded from the side of the connecting plate 1. The rotating block 11 can quickly drive the snap ring 5 to rotate on the movable ring 4, so that the alignment block 10 can be quickly aligned with the alignment hole 9, thereby completing the stable installation of the connecting plate 1 and the movable ring 4.

[0036] To ensure that the movable ring 4 can drive the connecting plate 1 to deflect stably on the base 2, refer to Figure 2 , Figure 3 , Figure 4 Figure 5 and Figure 6A support mechanism for supporting the connecting plate 1 is provided in the cavity of the base 2. The support mechanism supports the connecting plate 1 so that the inner side of the movable ring 4 can rotate in close contact with the outer surface of the base 2. The support mechanism includes a support tube 17 fixed in the cavity of the base 2 and a ball hinge assembly for ball-jointing the middle of the connecting plate 1 with one end of the support tube 17; a cover body 18 is fixed on the open end of the base 2 by screws, and the cover body 18 is located between the connecting plate 1 and the base 2. A first mounting hole 19 is penetrated at the center of the cover body 18, and a second mounting hole 20 is penetrated at the center of the connecting plate 1. One end of the support tube 17 is penetrated with the first mounting hole 19 and the second mounting hole 20 in sequence and fixedly connected to the center of the bottom of the base 2. The ball hinge assembly includes a supporting ring 21 fixed in the first mounting hole 19, a plug-in ring 22 fixed in the second mounting hole 20, and a pressure ring 23 fixedly sleeved on one end of the support tube 17. The supporting ring 21, the plug-in ring 22, and the pressure ring 23 are all arranged in a bowl-shaped structure, and both ends are opened. The plug-in ring 22 is made of plastic material and has a certain deformation ability. In the process of installing the connecting plate 1 on the movable ring 4, the plug-in ring 22 in the second mounting hole 20 on the connecting plate 1 can be inserted between the pressure ring 23 and the supporting ring 21. The inner wall of the plug-in ring 22 is stably fitted with the outer wall of the pressure ring 23, and the outer wall of the plug-in ring 22 is stably fitted with the inner wall of the supporting ring 21, so that the plug-in ring 22, the supporting ring 21 and the pressure ring 23 are combined to form a stable ball-hinged secondary structure. Under the joint limiting action of the pressure ring 23 and the supporting ring 21, the plug-in ring 22 can drive the connecting plate 1 to swing in any direction around one end of the support tube 17, and at the same time, it can also prevent the connecting plate 1 from driving the movable ring 4 to move as a whole toward the bottom of the base 2, causing the inner wall of the movable ring 4 to be unable to rotate tightly with the outer wall of the base 2.

[0037] Since the drive assembly 3 is arranged in the cavity of the base 2, the motor 31 in the drive assembly 3 needs to be connected to the control power supply and control system through wires, so refer to Figure 1 and Figure 7A bottom cover 12 is installed on the side of the base 2 away from the connecting plate 1. The bottom cover 12 is buckled on the base 2, and a cavity for laying wires is reserved between the bottom cover 12 and the base 2. A lead hole for the wires to pass through is provided on one side of the bottom cover 12. In order to prevent water vapor from entering the cavity of the base 2 from the gap between the bottom cover 12 and the base 2, a mounting ring 13 is protruding from the base 2, and a mounting groove 14 for the mounting ring 13 to be snap-fitted and installed is provided on the bottom cover 12. The mounting ring 13 is plug-fitted with the mounting groove 14, and when the mounting ring 13 is installed in the mounting groove 14, the inner wall and outer wall of the mounting ring 13 are tightly fitted with the two side walls of the mounting groove 14 respectively. To prevent the mounting ring 13 from falling out of the mounting groove 14, a connecting assembly 15 for fixedly connecting the bottom cover 12 and the base 2 is provided between the two. The connecting assembly 15 includes a connecting block 152 provided on the outer wall of the mounting ring 13 and two connecting pieces 151 provided on the outer wall of the bottom cover 12. When the mounting ring 13 is inserted into the mounting groove 14, the connecting block 152 is clamped and fixed between the two connecting pieces 151, thereby realizing a quick installation connection between the base 2 and the bottom cover 12.

[0038] To further prevent moisture from entering through the gap between the base 2 and the bottom cover 12, refer to Figure 1 and Figure 7 A water retaining ring 16 is fixedly sleeved on the mounting ring 13 on the base 2. When the mounting ring 13 is snap-fitted and fixed in the mounting groove 14, the water retaining ring 16 fits tightly with the end of the bottom cover 12, effectively preventing water vapor from entering through the gap between the mounting ring 13 and the side wall of the mounting groove 14.

[0039] The implementation principle of a rearview mirror lens driver with a waterproof structure in the embodiment of the present application is as follows: first assemble the driver, first pre-set the snap ring 5 on one end of the movable ring 4, and quickly drive the snap ring 5 to rotate on the movable ring 4 through the rotating block 11, so that the alignment block 10 can quickly align with the alignment hole 9. Then push the connecting plate 1 towards the movable ring 4 with force, so that the alignment block 10 is inserted into the alignment hole 9, at this time, the block 6 on the movable ring 4 is inserted into the groove 7 on the inner wall of the snap ring 5, and the inner wall of the plug-in ring 22 is stably fitted with the outer wall of the pressure ring 23, and the outer wall of the plug-in ring 22 is stably fitted with the inner wall of the supporting ring 21, and the stable connection between the connecting plate 1 and the base 2 can be completed. Then the two ends of the rack 33 are fixedly connected to the two sides of the connecting plate 1 respectively. Finally, pass the wire at one end of the base 2 through the lead hole on the bottom cover 12, align the connecting block 152 on the base 2 with the gap between the two connecting pieces 151 on the bottom cover 12, and buckle the bottom cover 12 on the base 2 with force, thus completing the assembly of the driver.

[0040] After the driver is assembled, the bottom cover 12 of 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 1 of the driver. By starting the two motors 31, the two motors 31 simultaneously drive the two gears 32 to rotate, and the two gears 32 drive the rack 33 to rotate in the cavity of the base 2, thereby driving the connecting plate 1 to perform a yaw motion on the base 2, and completing the angle adjustment of the rearview mirror lens.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
