Problems solved by technology
[0004] In the related art, the reflector is usually directly fixed and installed on the movable part of the voice coil motor by glue. When the glue is cured, the movable part needs to be heated. In addition, when the voice coil motor is working, the coil needs to be connected Direct current, the coil will generate heat when it is energized, and the heat generated can also be transferred to the movable parts. The above two reasons will cause thermal expansion and contraction of the movable parts and the mirror on the movable parts
Due to the different materials of the reflector and the movable parts, when the temperature changes, the thermal expansion and contraction of the two are not the same, resulting in stress, which easily deforms the reflector and reduces the surface accuracy, thereby affecting the optical performance of the reflector and causing The camera effect of the module is not ideal

The invention provides a movable part, a motor, a lens module and electronic equipment. The movable part comprises a movable base which is used for bearing a reflecting element; and an elastic connecting piece is used for elastically connecting the reflecting element and the movable base, wherein the elastic connecting piece comprises a first connecting part and a second connecting part, the first connecting part is fixedly connected to the movable base, and the second connecting part is used for fixedly connecting the reflecting element. According to the movable part, the elastic connecting piece is arranged on the movable part, and the elastic connecting piece can elastically connect the reflecting element to the movable part, so that the influence of temperature change on the surface precision of the reflecting element can be reduced, and the stability of the performance of the camera module is improved.
Description
technical field [0001] The present application relates to the field of image technology, and more specifically, to a movable part, a motor, a lens module and an electronic device. Background technique [0002] High-power optical zoom has always been the development trend of smart phone cameras, but due to the trend of thinner and lighter smart phones, the traditional lens module structure will not be able to meet the requirements of high-power optical zoom. Therefore, periscope lenses have moved towards the stage of mobile phone cameras. Long-distance zooming is possible. Existing periscope camera modules usually have the function of optical image stabilization (OIS), so as to improve the quality of photographing and enhance the photographing experience of users. [0003] Optical image stabilization technology is to transmit the signal to the image chip to calculate the displacement to be compensated when the gyroscope in the mobile phone detects a small movement, and then ...
