Problems solved by technology

When the movement is placed in the horizontal direction, the shock-absorbing assembly of the movement can make the optical pickup driving part in a suspended state, and elastically support the optical pickup driving part to play a shock-absorbing role; but this shockproof connection assembly The structure of the optical pickup is relatively complicated. If the movement is placed in the vertical direction or placed at a large inclination angle relative to the horizontal direction, the driving part of the optical pickup will deviate from the original position in the base due to the effect of gravity, so that when the The disc will be chucked when it enters and exits; in addition, in the case of continuous vibration, even if the movement is placed in a horizontal direction, the vibration will cause the drive part of the optical pickup to deviate from its original position in the base, which will cause reading The disk is not continuous and affects the use

Abstract

A shock absorption connection assembly in shock absorption combination component of core for optical disc playing unit consists of support seat in barrel type with opening upwards and central hole on its bottom plate, shock absorption pad prepared by elastic material in cylinder shape with through connection hole at center and ring embedded connection slot at external side .It features that shock absorption pad is connected on support seat in elastic - embedded way through its ring embedded slot and central hole on support seat.

Description

technical field [0001] The present invention relates to the assembly of the core of the optical disc playing device. Background technique [0002] The anti-seismic performance of the optical disc player is an important item of the technical index of the optical disc player. In order to make its optical disc player more widely used, certain measures must be taken on the shockproof of the movement. The core of an existing slot-in optical disc player has a base, an upper cover plate, a guide roller assembly, a transmission mechanism, a control assembly, an optical pickup driving part, an anti-vibration connection assembly and a pressure plate assembly. The platen frame of the platen assembly is rotatably connected to the base of the drive part of the optical pickup; the guide roller assembly is hinged to the front of the base through its guide roller frame; the main control side slide plate of the control assembly is arranged on the right side of the base, and It can slide ba...
