Sliding cover open-close device for sliding cover mobile phone

Abstract

The present invention relates to sliding cover opening / closing device for sliding cover mobile phone, it comprises: a first chain plate having a first shaft parallel arranged on the fixing frame and sliding frame and fixed on the fixing frame by a first shaft pin with rotatably mode; a second chain plate having a second shaft corresponding to the first shaft and fixed on the fixing frame by the first shaft pin with rotatably mode; a connecting plate having a first and a second pilot holes on its two ends so as to guide the first and the second shafts to slide action; a first and a second compression ring shape spring separately mounted on external diameters of the first and the second shafts, leading the sliding frame to elastic slide action along the fixing frame after bearing some outside force and leading the mobile phone cover to open / close small keyboard; and a traveling proof mechanism for preventing the first and the second chain plates from traveling phenomenon when sliding between two ends of the connecting plate.

Description

technical field [0001] The invention relates to a sliding cover opening and closing device for a sliding mobile phone, in particular to a sliding cover opening and closing device for a sliding mobile phone that can greatly reduce the friction noise of a mobile phone that slides up and down to open and close and improve the reliability of the action. Background technique [0002] As we all know, mobile phones can be classified into bar type (Bar), folding type (Flip), flip type (Folder) and slide type (Slide) etc. according to the opening and closing methods. [0003] The candy bar mobile phone is prone to erroneous actions because its keypad (Keypad) is exposed to the outside. The foldable mobile phone cannot be reduced in size due to the need to ensure the distance between the transmitting part and the receiving part. The distance between the transmitting part and the receiving part is beneficial to reduce the size. [0004] The slide-type mobile phone includes: a main bod...

AI Technical Summary

Problems solved by technology

[0007] However, the existing torsion springs exert elastic force in all directions when the sliding frame slides, and then rub against the surfaces of the sliding frame and the fixed frame and generate noise

[0008] Moreover, after the sliding frame slides about 100,000 times, the torsional force of the existing torsion spring will be significantly reduced, causing problems such as breakage or malfunction.
