  • the first positioning member 2561 and the second positioning member 2565 of the embodiment of the present application can position the hinge device 25 at the bending position and the unfolding position, respectively.
  • the elastic force generated by the first positioning member 2561 and the second positioning member 2565 can make the hinge
  • the state of the device 25 at the bending position and the unfolding position is relatively stable, that is, a certain initial force needs to be applied to deform the hinge device 25, so that it is not easily affected by its own gravity to accidentally expand or bend.
  • the term “relative sliding” in the present invention does not limit the direct contact and relative sliding between two components, but may also include relative sliding between third-party components, and the third-party components are not limited to physical components, such as tablets. Materials, membranes, etc., but can also contain non-physical components, such as gaps, spaces, etc., or a combination of physical and non-physical components; third-party components are not limited to one, but can include multiple. That is to say, as long as the two elements have a relative sliding motion relationship, regardless of the actual positions of the two elements, they can be regarded as within the scope of the “relative sliding” referred to in the present invention.

Abstract

Dispositif de charnière (25), coque (20) d'un dispositif électronique, et dispositif électronique (100). Un écran flexible (30) est agencé sur la coque (20). La coque (20) comprend des corps (21, 23) de cadre et le dispositif de charnière (25). Le dispositif de charnière (25) est agencé sur les corps (21, 23) de cadre. Le dispositif de charnière (25) comprend un premier maillon de chaîne (251), un second maillon de chaîne (253) s'articulant sur le premier maillon de chaîne (251), et un mécanisme de positionnement (256). Le premier maillon de chaîne (251) comprend une première rainure de positionnement (2511) et une seconde rainure de positionnement (2513) ; le second maillon de chaîne (253) est pourvu d'un trou de positionnement (2532) ; le mécanisme de positionnement (256) comprend une pièce de positionnement (2561) ; et une première extrémité de la pièce de positionnement (2561) est reliée dans le trou de positionnement (2532). Lorsque le dispositif de charnière (25) est dans un état d'extension, une seconde extrémité de la pièce de positionnement (2561) est reliée mobile dans la première rainure de positionnement (2511), et lorsque le dispositif de charnière (25) est dans un état de flexion, la seconde extrémité de la pièce de positionnement (2561) est reliée mobile dans la seconde rainure de positionnement (2513). La pièce de positionnement permet au dispositif de charnière d'être maintenu de manière stable dans l'état d'extension ou l'état de flexion, de telle sorte que l'effet de positionnement est bon.
