A mobile phone security lifting camera

Abstract

The invention belongs to the field of mobile phones, and particularly relates to a mobile phone safety lifting camera, which includes electric drive, screw, nut, A tube, sleeve, B tube, A slider, booster spring, extension spring, sliding plate, compression spring, etc. , wherein the electric drive drives the screw to rotate to make the nut move up and down, the nut drives the A tube to move up and down, and the A tube drives the camera to move up through the sleeve, B tube, booster spring, A slider, and base. In the present invention, the booster spring is used to compress the small amplitude generated when the camera is hit. The booster spring partially compressed by the small range buffers the impact of the camera. After the disk passes through a series of transmissions, the relatively static state between the A tube and the sleeve is instantly released; thus, under the reset action of the tension spring, the B tube is pulled down to move down instantly, and the down-moving B tube instantly retracts the camera to the body after a series of transmissions In this way, the possibility of the camera being damaged by impact is greatly reduced.

Description

technical field [0001] The invention belongs to the field of mobile phones, in particular to a mobile phone safety lifting camera. Background technique [0002] At present, with the evolution of mobile phone aesthetics and design, there is already a mobile phone on the market that can lift the camera; the camera of this mobile phone is normally shrunk inside the body, and when it needs to be used, it stretches out the screen to take pictures; the existing The lifting method of the camera in the technology often adopts the transmission form of the screw nut to drive the camera to expand and contract. [0003] If the existing mobile phone with the function of raising and lowering the camera accidentally drops the mobile phone when taking pictures, the camera that has protruded from the inside of the body is easily damaged by impact. In the prior art, in order to solve the problem of camera impact damage, three schemes are mainly adopted: [0004] The first one is to control ...

AI Technical Summary

Problems solved by technology

However, mobile phones using this structural solution require a large installation space, and this anti-collision effect cannot completely protect the camera, so only a small number of mobile phones on the market use this solution

[0006] The third is to buffer the strong impact force of the camera by pushing the camera out of the booster spring outside the body, but the reaction force provided by the booster spring to the camera, combined with the strong impact force received by the camera, makes the camera easier to be affected by the reaction force and the clamping of the impact force is damaged
