Folding screen rotary shaft and folding screen electric equipment

Abstract

The invention discloses folding screen rotary shafts and folding screen electric equipment. Link gears A and link gears B are linked with several shaft cores to form gear chain type rotary shafts, which can be bent into a certain radian and be expanded to rotate synchronously, a flexible screen bending place can be effectively supported during bending or opening process; and by enclosing the linkgears A and link gears B on the shaft cores, the function of damping is achieved during bending or opening process. By designing compensation components on the shaft cores, the position offset causedby bending can be compensated, which avoids the pulling force on the flexible screen caused by bending or opening process, and ensures the stability of the flexible screen, and in addition, the structure is simple, and the thickness of the product is greatly reduced. Since inclined guide sliding blocks need to be driven in both the axial direction and the expanding direction, the inclined guide sliding blocks can move in inclined guide grooves, so that the rotary shafts can be prevented from moving back and forth when the rotary shafts are assembled on the finished product.

Description

technical field [0001] The invention relates to the technical field of folding screens, in particular to a folding screen rotating shaft and folding screen electronic equipment. Background technique [0002] With the upgrading of electronic products, the display screens of various electronic equipment terminals, such as mobile phones and tablet computers, are becoming larger and larger. This is because larger display screens can provide users with richer information and improve human health. It can improve the efficiency of machine communication and bring a better user experience. However, with the increase of the screen, the size of the terminal base of the electronic device will increase accordingly; the increase in the size of the base of the electronic device will bring about the problem of inconvenient carrying and storage, which restricts the expansion of the display screen. . At present, the folding screen technology has found a good compromise between the miniaturi...

AI Technical Summary

Problems solved by technology

However, in these existing technical solutions, the structure of the rotating shaft is very complicated, and the bending radius of the screen is large, resulting in a large thickness of the product, and a pulling force will be generated on the flexible screen during the bending or opening process, affecting the stability of the flexible screen
