Foldable screen inward folding synchronous rotating mechanism and electronic equipment

Abstract

The invention discloses a foldable screen inward folding synchronous rotating mechanism and electronic equipment. The mechanism comprises first and base bases, first and second tooth frames and a synchronous transmission module; the synchronous transmission module comprises first and second shafts, first and second transmission wheels and first and second planet gears; the first and second shaftsare rotationally mounted on the first and second bases; the first transmission wheel and the first planet gear are synchronously mounted on the first shaft; the second transmission wheel and the second planet gear are synchronously mounted on the second shaft; the first and second transmission wheels are in transmission connection through a transmission mechanism; the back surfaces of first and second slide blocks of the first and second tooth frames are slidingly connected with first and second slide rail grooves through first and second arc surfaces; and the top surfaces of the first and second slide blocks are in engaged transmission connection with the first and second planet gears through first and second arc teeth. The mechanism can realize inward folding of foldable screens by 180 degrees to compensate the position offset caused by bending to guarantee stability of the foldable screens, and is simpler in structure.

Description

technical field [0001] The invention relates to the technical field of folding screens, in particular to a synchronous rotating mechanism for folding inward folding of a folding screen and 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...

Problems solved by technology

However, with this structure, the bending radius of the screen is relatively large, resulting in a large product thickness, and a pulling force will be generated on the folding screen during the bending or opening process, which will affect the stability of the folding screen.

There are also some other technical solutions, such as the double-fold synchronous rotation mechanism inside and outside the flexible screen disclosed in the patent document CN 110131299A. However, these technical solutions have very complicated structures, many parts, and relatively high production and processing costs.
