Detailed Implementation

[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0026] The terms used in this application, such as top, bottom, left, right, inside, outside, front end, rear end, head, and tail, are based on the orientations or positional relationships shown in the accompanying drawings. Different drawings may result in different positional relationships, therefore they should not be construed as limiting the scope of protection.

[0027] In this utility model, the terms "installation," "connection," "interlocking," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, or a connection that allows communication between components. They can also refer to a direct connection or an indirect connection through an intermediate medium. Furthermore, they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] like Figures 1 to 4 As shown in the figure, this embodiment describes an electronic exterior rearview mirror folding mechanism, which mainly includes a fixed base 100 and a folding arm 200. Both the fixed base 100 and the folding arm 200 are made of metal, such as stainless steel, to ensure structural strength.

[0029] One end of the fixed base 100 is fixedly connected to the vehicle body, and the other end is rotatably connected to the connecting part 210 of the folding arm via a pin 300. Furthermore, a bump-concave structure composed of grooves and protrusions is provided on the two opposing rotating surfaces between the fixed base 100 and the connecting part 210 of the folding arm. (See [reference]). Figure 1In the embodiment, the fixed seat body 100 is provided with a pin shaft hole 101 for connecting the pin shaft 300, and the rotating surface 110 of the fixed seat body 100 is provided with three sets of circumferentially distributed grooves 111, and the rotating surface of the connecting part 210 of the folding arm is provided with three sets of protrusions corresponding to the grooves 111. The edges of the protrusions and the inner angles of the grooves are both circular arcs, which facilitates the sliding of the protrusions out of the grooves and the folding. When the fixed seat body 100 and the folding arm 200 rotate relative to each other, the protrusion-groove structure changes between the aligned and misaligned states.

[0030] The rotating surface 110 of the fixed seat body is provided with a positioning ring 120 coaxial with the pin shaft hole, and the positioning ring is a tapered ring, i.e., small at the top and large at the bottom. The connecting part 210 of the folding arm is provided with an inner tapered hole 220 corresponding to the tapered ring; the connecting part of the folding arm is sleeved outside the positioning ring 120 through the inner tapered hole 220. Compared with the positioning ring and the inner sleeve hole with consistent upper and lower diameters in the prior art, the structure is accurate in positioning during assembly and eliminates the influence of the manufacturing process on assembly.

[0031] A stop ring 310 for installing a compression spring is arranged at one end of the pin shaft 300 close to the folding arm. A compression spring 400 is sleeved on the pin shaft, and a soundproof gasket 320 is arranged between the stop ring 310 and the compression spring 400 to reduce noise during rotation. The soundproof gasket 320 can be made of PEEK material and has the characteristics of sound reduction and wear resistance.

[0032] A stepped surface 221 for facilitating the installation of the compression spring 400 is arranged on the inner tapered hole 220 of the connecting part of the folding arm.

[0033] The other end of the pin shaft 300 passes through the connecting part 210 of the folding arm and the fixed seat body 100, is limited in the axial direction by the fixed seat body 100, and the compression spring 400 is compressed between the stop ring 310 of the pin shaft and the folding arm 200, so as to tightly press the fixed seat body 100 and the folding arm 200 together, so that the rotating surfaces of the fixed seat body 100 and the folding arm 200 are tightly attached together.

[0034] In the embodiment, the inner surface of the pin shaft hole of the fixed seat body 100 is provided with an L-shaped guide groove 102, and the end of the pin shaft is provided with a slider 301 movable along the L-shaped guide groove, so as to realize the limitation of the pin shaft in the axial direction by the fixed seat body. During installation, the slider 301 of the pin shaft is first slid along the vertical part of the L-shaped guide groove 102, and after reaching the predetermined position, the pin shaft 300 is rotated so that the slider 301 slides along the horizontal part of the L-shaped guide groove 102, achieving the purpose of limiting the pin shaft in the axial direction by the fixed seat body.
