Inner folding hinge and inner folding mobile terminal

Abstract

The invention discloses an inner folding hinge and an inner folding mobile terminal, the inner folding hinge comprises a hinge mechanism, and the hinge mechanism comprises a synchronizing mechanism which is internally provided with a gear set used for providing terminal mechanical sense feedback and ensuring smooth rotation of the hinge; locking mechanisms, each of which is provided with an elastic part generating elastic supporting force and preventing a terminal shell from drooping or being folded excessively under the effect of natural gravity; screen supporting and avoiding mechanisms which are mounted corresponding to left and right lifting plates and are used for supporting a screen when the hinge is opened and avoiding space to bend the screen when the hinge is closed; and a slide rail mechanism which is mounted at the bottoms of left and right cover plates, prevents the screen from bulging and clings to the surface. According to the inner folding hinge, the same structure and asymmetrical installation mode are adopted for the same action structure in the inner folding hinge, the structural complexity of the inner folding hinge is greatly simplified, meanwhile, the stability of the hinge during opening and closing is ensured, and then the inner folding hinge can be better adapted to various mobile terminals.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to an inward-folding hinge and an inward-folding mobile terminal. Background technique [0002] Since large-screen mobile phones have obvious advantages in terms of visual and entertainment experience compared with small-screen mobile phones, most of the current flagship mobile phone products of mainstream manufacturers tend to have large-screen designs. However, large-screen mobile phones have relatively large disadvantages in terms of grip comfort and portability. With the gradual commercialization of flexible display panels, folding mobile phones are becoming the main direction of the development of next-generation mobile phones by mainstream equipment manufacturers because of the characteristics of flexible display panels in different usage scenarios. [0003] Among them, the inner folding mobile phone is a common type of common folding mobile phones. In the process of produ...

Problems solved by technology

[0004] The purpose of the present invention is to provide an inner folding hinge and an inner folding mobile terminal to solve the problem of the traditional inner folding hinge structure proposed in the above background technology with many and complicated action mechanisms, and various types of action mechanisms no matter in the design process or in the manufacturing process. Both need to invest a lot of labor cost and time cost. At the same time, during the rotation process of the traditional hinge, due to the complex action mechanism, the stability is low. At the same time, when it is actually applied to the mobile terminal, the inner folding hinge with complex structure is easier to damage the flexible hinge. Problems with the display
