Stretching type mobile equipment with variable screen width

Abstract

A stretching type mobile equipment with a variable screen width comprises a flexible screen, a stretching assembly and a shell for installing the stretching assembly and the flexible screen; the shell comprises a first stretching shell and a second stretching shell which are transversely matched with each other; the stretching assembly comprises a first supporting piece and a second supporting piece which are fixed to the first stretching shell and the second stretching shell respectively, and the flexible screen comprises a fixed end fixed to the transverse outer side of the second stretching shell and a movable end elastically fixed between the stretching assembly and the shell; the first stretching shell and the second stretching shell move in the transverse direction and drive the first supporting piece and the second supporting piece to be opened and closed, and meanwhile the movable end of the flexible screen is promoted to change the transverse position, so that the width of the flexible screen on the upper side of the stretching assembly is changed. The screen width can be stably adjusted, and the screen is protected.

Description

technical field [0001] The present application relates to the field of communications, in particular to a stretchable mobile device with variable screen width. Background technique [0002] At present, variable screen width technology has begun to be applied in the field of mobile communications. There are a large number of folding screen mobile phones on the market. Folding screen mobile phones are generally realized by hinge mechanisms. It is necessary to maintain a certain compensation between the inside and the outside at the bend of the screen to avoid damage to the screen. In order to ensure the above technical requirements, the hinge is equipped with a variety of devices, such as synchronization and stabilization devices, etc. There are a lot of components, and the cost is very high, and the stability is worse than that of the existing fixed-screen mobile phones. [0003] At the same time, the complexity of folding hinges has caused great problems in mass production....

AI Technical Summary

Problems solved by technology

In order to ensure the above technical requirements, the hinge is equipped with a variety of devices, such as synchronization and stabilization devices, etc. There are many components, and the cost is very high, and the stability is worse than that of existing mobile phones with fixed screens.

[0003] At the same time, the complexity of folding hinges has caused great problems in mass production. Too many activities and rotating components have restricted the stability of the product, so a stretched structure has begun to appear in mobile phones with variable screen widths, such as Chinese patent application No. 201110062641.6 discloses a mobile device with variable screen width, which realizes the stretching of the screen by fixing one end of the screen and winding and curling the other end. This technical solution cannot be realized in the existing flexible screen technology , first of all, flexible screen bending has a certain bending angle limit, and the inner screen that has been wound multiple times and multi-layered will be damaged, and this winding technology needs to leave room for the multi-layer winding of the flexible screen. Enough space is not conducive to the utilization of the internal space of mobile devices

Moreover, this technical solution only reveals the concept of a stretched screen, and does not give a specific solution for how to ensure the support and stretching synchronization of the flexible screen.
