Problems solved by technology

However, the large contact area between the protruding structure and the fixed components will not only make it difficult to remove the original stains and easily carry pollutants from the cleaning solution, but also lengthen the drying time and affect the drying effect
Incomplete drying and contamination will cause the fixed components to easily stick to the fixed components and affect the actuation performance of the voice coil motor

Abstract

A voice coil motor comprises a base, a casing, a fixing component and a moving component. The base comprises a first surface, and the casing is arranged on the base. The casing comprises an accommodation space, and the fixing component is accommodated in the accommodation space and born on the first surface. The fixing component comprises a fixing frame, and the moving component is arranged in the fixing frame. The moving component comprises a moving installation cylinder which is provided with a through accommodation hole. The moving installation cylinder further comprises a bottom surface right aligning with the first surface, and at least two protruding blocks are arranged on the bottom surface. The protruding blocks are contacted with the base and comprise end surfaces away from the bottom surface, the end surfaces extend from the middle to two ends to form two inclined surfaces, and the area of contact surfaces of the protruding blocks with the base is reduced due to the inclined faces.

Description

technical field [0001] The invention relates to a voice coil motor. Background technique [0002] Voice coil motors are widely used in actuation systems in electronic products due to their small size, low power consumption, and precise movement displacement. The voice coil motor mainly includes a moving component, a fixed component, a coil and a magnet arranged between the moving component and the fixed component. The moving component can be in contact with the fixed component in an unfocused state and maintain a fixed position, and can also move relative to the fixed component under electromagnetic action to achieve focusing. [0003] At present, in order to make the moving component in contact with the fixed component when the voice coil motor is in the non-focus state and be able to withstand a certain impact and keep the position unchanged, a protruding structure is usually provided on the moving component, and the protruding structure is in contact with the fixed compo...
