Motion shock suppression system based on voice coil motor actuation and photographic lens

Abstract

This invention relates to the field of photography technology and provides a motion impact suppression system and photographic lens based on a voice coil motor actuation. The system includes: a housing assembly; a guide assembly disposed inside the housing assembly, with a first guide shaft and a second guide shaft symmetrically arranged on both sides of the housing assembly; a member to be protected, sleeved on the first and second guide shafts; a baffle assembly detachably connected to one end of the housing assembly; a first buffer member assembled on the side of the baffle assembly facing the member to be protected; and a second buffer member arranged axially between the member to be protected and the baffle assembly, along with the first buffer member. The first buffer member is used to elastically deform when the member to be protected is impacted to form a primary buffer, and the second buffer member is used to elastically deform together with the first buffer member to form a secondary buffer, thereby forming a graded buffer protection for the member to be protected, significantly improving buffering efficiency.
