Folding screen mobile phone unfolding, closing and locking mechanism

Abstract

The invention relates to a folding screen mobile phone unfolding, closing and locking mechanism which is provided with a sealing cover, a connecting rod, a connecting rod, an elastic piece and a locking piece. Threaded holes are symmetrically formed in the left and right sides of the sealing cover; connecting through holes in one-to-one correspondence with the threaded holes are formed in the locking plate; two connecting rods are symmetrically arranged on the left side and the right side of the sealing cover; the connecting rods are positioned between the sealing cover and the locking plate;the threaded parts of the connecting rods sequentially penetrate through the connecting through holes in the locking plate and the through holes in the connecting rods and then is connected and matched with the threaded hole in the sealing cover; the gear parts of the two connecting rods are in transmission fit with each other; a groove is formed in the end face, facing the locking piece, of the gear part, a boss correspondingly matched with the groove to form locking is arranged on the end face, facing the gear part, of the locking piece, and the elastic piece is arranged on the connecting rod in a sleeving mode and located between the pressing head and the locking piece. The pressing head acts on the elastic piece, and the elastic piece presses the locking piece. The problem that the current unfolding or closing state needs to be deliberately controlled when the folding screen mobile phone is in the unfolding or closing state can be effectively solved, and the user experience is effectively improved.

Description

technical field [0001] The invention relates to mobile phone components, in particular to an unfolding and closing locking mechanism for a folding screen mobile phone. Background technique [0002] With the continuous development of mobile phone technology, people's functions of mobile phones are not limited to communication, and more and more functions are given to mobile phones, especially mobile phones have begun to replace some computer functions, such as office. With the continuous development of flexible screen technology, now through the application of flexible screens on mobile phones, folding screen mobile phones have been invented. Since the screen of a folding screen mobile phone can be folded, people can switch between a large screen and a small screen. [0003] In existing folding screen mobile phones, the folding shaft in the middle is a mechanical structure, which is carried out by hinges and other guiding methods. However, there are still the following defic...
