Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to an electric folding rearview mirror substrate. Background Technology

[0002] Car rearview mirrors are located on the left and right sides of the front of the car, as well as in the front of the interior. They reflect the situation behind, to the sides, and below the car, allowing the driver to indirectly see these areas. They act as a "second eye," expanding the driver's field of vision.

[0003] Rearview mirrors typically have a base plate inside, and an adjustment component is installed in the base plate to adjust the angle of the lens. In the existing electric folding rearview mirror base plate structure, the adjustment component is usually fixed to the base plate by bolts. The adjustment component is fastened to the base plate by multiple bolts to achieve stable assembly. However, this connection method has low assembly efficiency, requires tightening each bolt individually, and is cumbersome to operate, increasing the assembly time of the production line, affecting the overall production efficiency, and making maintenance inconvenient. If it is necessary to disassemble or replace the motor, each bolt must be removed, which is not only time-consuming and labor-intensive, but may also cause thread wear due to repeated disassembly and assembly, affecting the reliability of the connection. Summary of the Invention

[0004] The purpose of this application is to improve the assembly speed of the adjustment components and the substrate.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A substrate is included, the substrate having an internal mounting groove, the inner wall of which has multiple telescopic grooves, a rotating groove, and a moving groove. A screw is movably mounted inside the moving groove, with knobs fixedly connected to both ends of the screw. A moving plate is provided inside the moving groove, and a turntable is provided inside the rotating groove. Multiple linkage grooves are provided inside the turntable, and each of the multiple telescopic grooves has a locking plate. A linkage post is provided on the side of the locking plate facing the turntable, and the linkage post is located inside the linkage groove. An annular groove is provided on the inner wall of the rotating groove, and a limit ring is provided on the inner wall of the turntable, with the limit ring located inside the annular groove.

[0006] As a preferred embodiment, the mounting groove is connected to the rotating groove through multiple telescopic grooves, and the bottom of the movable plate and the outer wall of the turntable are provided with toothed grooves, with the bottom of the movable plate engaging with the outer wall of the turntable.

[0007] As another preferred embodiment, the substrate is provided with an adjustment component inside, and a mounting block is fixedly connected to the side of the adjustment component facing the substrate. The outer wall of the mounting block is provided with a locking groove, and there are multiple locking grooves. One end of the locking plate is located inside the locking groove.

[0008] In a further preferred embodiment, the locking plate is inclined at one end of the locking groove, and the inner wall of the locking groove that is in contact with the end of the locking plate is also inclined.

[0009] Further preferably, the inner wall of the substrate is provided with positioning holes, and there are multiple positioning holes. The side of the adjustment component facing the substrate is fixedly connected with positioning posts, and there are multiple positioning posts. The multiple positioning posts are respectively located inside the multiple positioning holes.

[0010] Further preferably, the outer wall of the substrate is provided with heat dissipation grooves, and there are multiple heat dissipation grooves, which are respectively located on the longitudinal surface and the right outer wall of the substrate.

[0011] Further preferably, the outer wall of the substrate is fixedly connected with a fixing plate, and there are multiple fixing plates.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) Before installing the adjustment assembly, multiple locking plates retract into their corresponding telescopic grooves. Insert the mounting block connected to the back of the adjustment assembly into the mounting groove. After the mounting block is fully inserted into the mounting groove, turn the knob to drive the screw to rotate synchronously. Taking the movable plate in the attached diagram as an example, move the movable plate connected to the outer wall to the right. Since the bottom of the movable plate engages with the outer wall of the turntable, and the limiting ring set on the inner wall of the turntable is located in the annular groove opened on the inner wall of the mounting groove, the turntable rotates clockwise. When the turntable rotates clockwise, the linkage column connected to the outer wall of the locking plate moves along the linkage groove opened inside the turntable. At the same time, under the limiting action of the telescopic groove, the locking plates move into the locking groove opened inside the mounting block until the inclined end of the locking plate enters the interior of the locking groove and is tightly attached to the inner wall of the locking groove. At this time, the adjustment assembly is fixed inside the base plate. When maintaining the adjustment assembly, turn the knob in the opposite direction. In the same way, the turntable can be rotated in the opposite direction, so that the multiple locking plates retract into their corresponding telescopic grooves. The process of disassembling and assembling the adjustment assembly is quick and convenient, saving the time of disassembling the bolts one by one. Attached Figure Description

[0029] like Figure 1-10The illustrated electrically folding rearview mirror base plate includes a base plate 1. The base plate 1 has a mounting groove 2 inside, and multiple telescopic grooves 3 are formed on the inner wall of the mounting groove 2. A rotating groove 4 is also formed inside the base plate 1, and the mounting groove 2 is connected to the rotating groove 4 via multiple telescopic grooves 3. A movable groove 5 is formed inside the base plate 1, and a screw 6 is movably mounted inside the movable groove 5. Knobs 7 are fixedly connected to both ends of the screw 6. A movable plate 8 is disposed inside the movable groove 5, and a turntable 9 is disposed inside the rotating groove 4. Gear grooves are formed on the bottom of the movable plate 8 and the outer wall of the turntable 9, with the bottom of the movable plate 8 meshing with the outer wall of the turntable 9. Multiple linkage grooves 10 are formed inside the turntable 9, and locking mechanisms are provided inside each of the multiple telescopic grooves 3. A linkage post 12 is provided on the side of the locking plate 11 facing the turntable 9. The linkage post 12 is located inside the linkage groove 10. An annular groove 13 is provided on the inner wall of the rotating groove 4. A limit ring 14 is provided on the inner wall of the turntable 9. The limit ring 14 is located inside the annular groove 13. An adjustment assembly 15 is provided inside the base plate 1. The adjustment assembly 15 includes a pitch motor and a yaw motor. The pitch motor controls the vertical angle of the lens, and the yaw motor controls the horizontal angle of the lens. These are existing components in this field. Inside the adjustment assembly 15, a mounting block 16 is fixedly connected to the side of the adjustment assembly 15 facing the base plate 1. A locking groove 17 is provided on the outer wall of the mounting block 16, and there are multiple locking grooves 17. One end of the locking plate 11 is located inside the locking groove 17.

[0030] Before installing the adjustment assembly 15, multiple locking plates 11 retract into their corresponding telescopic grooves 3. The mounting block 16 connected to the back of the adjustment assembly 15 is inserted into the mounting groove 2. After the mounting block 16 is fully inserted into the mounting groove 2, the knob 7 is rotated to drive the screw 6 to rotate synchronously. Taking the movable plate 8 in the attached diagram as an example, the movable plate 8 with its outer wall threaded connection moves to the right. Because the bottom of the movable plate 8 engages with the outer wall of the turntable 9, and the limiting ring 14 on the inner wall of the turntable 9 is located in the annular groove 13 on the inner wall of the mounting groove 2, the turntable 9 rotates counterclockwise. When the turntable 9 rotates clockwise, the linkage column connected to the outer wall of the locking plate 11... 12 moves along the linkage groove 10 inside the turntable 9. At the same time, under the limiting action of the telescopic groove 3, the locking plate 11 moves into the locking groove 17 inside the mounting block 16 until the inclined end of the locking plate 11 enters the interior of the locking groove 17 and is tightly attached to the inner wall of the locking groove 17. At this time, the adjusting component 15 is fixed inside the base plate 1. When maintaining the adjusting component 15, the knob 7 is rotated in the opposite direction. In the same way, the turntable 9 can be rotated in the opposite direction, so that the multiple locking plates 11 are retracted into the interior of their corresponding telescopic grooves 3. The entire process of adjusting component 15 is quick and easy to disassemble and assemble, saving the time of disassembling the bolts one by one.

[0031] The locking plate 11 is located at one end of the locking groove 17 with an inclined surface. The inner wall of the locking groove 17 is in contact with the end of the locking plate 11 with an inclined surface, so that the inclined end of the locking plate 11 is in contact with the inclined surface of the inner wall of the locking groove 17. By using the mutual pressing of the two inclined surfaces, the adjusting component 15 is pressed tightly inside the base plate 1.

[0032] The inner wall of the substrate 1 is provided with positioning holes 18, and there are multiple positioning holes 18. The side of the adjustment component 15 facing the substrate 1 is fixedly connected with positioning posts 19, and there are multiple positioning posts 19. The multiple positioning posts 19 are located inside the multiple positioning holes 18, so that after the adjustment component 15 is installed in the substrate 1, the multiple locking grooves 17 opened on the outer wall of the mounting block 16 can correspond to the multiple telescopic grooves 3 respectively.

[0033] The outer wall of the substrate 1 is provided with heat dissipation grooves 20, and there are multiple heat dissipation grooves 20. The multiple heat dissipation grooves 20 are located on the longitudinal surface and the right outer wall of the substrate 1, respectively. The heat generated by the pitch motor and the yaw motor during operation can be discharged to the outside through the heat dissipation grooves 20.

[0034] The outer wall of the substrate 1 is fixedly connected with a fixing plate 22, and there are multiple fixing plates 22, which makes it convenient to install the substrate 1 on the rearview mirror.

[0035] Working principle: Before installing the adjustment component 15, multiple locking plates 11 retract into their corresponding telescopic grooves 3. The mounting block 16 connected to the back of the adjustment component 15 is inserted into the mounting groove 2. Once the mounting block 16 is fully inside the mounting groove 2, the knob 7 is rotated to drive the screw 6 to rotate synchronously. Taking the movable plate 8 in the attached diagram as an example, the movable plate 8 with its outer wall threaded connection moves to the right. Because the bottom of the movable plate 8 engages with the outer wall of the turntable 9, and the limiting ring 14 on the inner wall of the turntable 9 is located in the annular groove 13 on the inner wall of the mounting groove 2, the turntable 9 rotates counterclockwise. When the turntable 9 rotates clockwise, the locking plate 11's outer wall threaded connection... The moving column 12 moves along the linkage groove 10 inside the turntable 9. At the same time, under the limiting action of the telescopic groove 3, the locking plate 11 moves into the locking groove 17 inside the mounting block 16 until the inclined end of the locking plate 11 enters the interior of the locking groove 17 and is tightly attached to the inner wall of the locking groove 17. At this time, the adjusting component 15 is fixed inside the base plate 1. When maintaining the adjusting component 15, the knob 7 is rotated in the opposite direction. In the same way, the turntable 9 can be rotated in the opposite direction, so that the multiple locking plates 11 are retracted into the interior of their corresponding telescopic grooves 3. The entire process of adjusting component 15 is quick and easy to disassemble and assemble, saving the time of disassembling the bolts one by one.
