[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figures 1 to 3 The utility model provides a technical solution: a wave spring for a rearview mirror rotation drive mechanism, comprising a wave spring body 1, a spring seat 2 is arranged under the wave spring body 1, a spring pressure ring 3 is detachably connected to the spring seat 2, a rotating ring 4 is rotatably connected to the spring pressure ring 3, a fixing part for pressing the wave spring body 1 is arranged on the rotating ring 4, the wave spring body 1 has a wave shape in shape, the fixing part can press the wave valley of the wave spring body 1, the wave valley at the required position on the wave spring body 1 is pressed by the fixing part, and then the spring pressure ring 3 is pressed downward to install the spring pressure ring 3 and the spring seat 2, so as to realize the length and elasticity adjustment of the wave spring body 1.

[0016] Among them, the fixed part includes a spring pressure block 6, a support plate 5 is installed on one side of the spring pressure block 6, and the support plate 5 is elastically connected to the top of the rotating ring 4. The support plate 5 can be pushed toward the outside of the rotating ring 4 to make the spring pressure block 6 disengage from the wave valley pressure on the wave spring body 1, and then adjust the position of the spring pressure ring 3 on the wave spring body 1.

[0017] Furthermore, a plurality of support plates 5 can be arranged on the rotating ring 4 according to actual conditions, and the lengths of the plurality of support plates 5 are different.

[0018] Among them, the spring pressing block 6 is of a cylindrical structure, and the outer shape of the cylindrical structure fits the outer shape of the corrugated spring body 1 more closely, facilitating the stable contact between the spring pressing block 6 and the corrugated spring body 1.

[0019] Among them, an inner platform 7 is arranged inside the spring seat 2, and the corrugated spring body 1 is installed on the inner platform 7. The inner diameter of the inner platform 7 is larger than the inner diameter of the corrugated spring body 1 and smaller than the outer diameter of the corrugated spring body 1, enabling the corrugated spring body 1 to be stably installed on the inner platform 7.

[0020] Among them, an avoidance hole 8 is arranged on the inner platform 7, and the diameter of the avoidance hole 8 is smaller than the inner diameter of the corrugated spring body 1, facilitating the passage of parts inside the corrugated spring body 1 and not affecting the use of the corrugated spring body 1.

[0021] Specifically, when it is necessary to adjust the length or elasticity of the corrugated spring body 1, the support plate 5 can be toggled towards the outer side of the rotating ring 4 to make the spring pressing block 6 disengage from the suppression of the trough on the corrugated spring body 1. After adjusting the spring pressing ring 3 to a suitable position on the corrugated spring body 1, rotate the rotating ring 4 to press the spring pressing block 6 on the corresponding trough of the corrugated spring body 1, and then press down the spring pressing ring 3. The spring pressing block 6 will press down the corrugated spring body 1, causing the corrugated spring body 1 to contract. The spring pressing ring 3 and the spring seat 2 are installed to achieve the adjustment of the length and elasticity of the corrugated spring body 1.
