Problems solved by technology

However, if the rotation angle exceeds 180 degrees, the driven member 37 will incline at a certain angle relative to the hinge shaft 34, and cannot perform flexible operation, resulting in the problem that it is difficult to perform corresponding rotation.

Embodiment Construction

[0028] The above object can be achieved by a hinge device for a mobile terminal provided by the present invention. In the present invention, for a mobile terminal connected with a lower flip cover and an upper flip cover that can move relatively, it is characterized in that the terminal includes the following structure: hinge shafts are distributed in parallel on one side edge of the upper flip cover or the lower flip cover; The cam is equipped with a cam profile with a height difference relative to the rotation center along the rotation direction of the hinge shaft, and is integrated and fixed with the hinge shaft; the driven member is along the axis direction of the hinge shaft , contact with the profile of the above-mentioned cam laterally, and perform relative movement relative to the cam; a spring member, which generates elastic force to ensure the close contact between the above-mentioned driven member and the above-mentioned cam.

Abstract

The invention realtes to a hinge device of mobile terminal, pertaining to a mobile communications domain, which is characterized in that for a mobile terminal linked with an upper flip and a lower flip that can carry out the relative movement between them, including the following structure modules: a hinge axis, which is installed side-by-side on one edge of the upper flip and the lower flip; a cam, which has a cam contour along the circumferential direction of the leaf axis center and having level differences relative to the rotary center, and is fixed with the leaf axis as a whole; driven components, which is the axis direction of the leaf axis, laterally contacts with the cam contour, and follows the above cam to carry out a relative movement; and spring components, which generates the elasticity to ensure the elastic contact between the driven components and the cam. A hinge device of mobile terminal can be provided by the invention, which can form a cam profile of a non-symmetric structure, thereby broadening the choice range of the rotating angle.

Description

technical field [0001] The invention relates to a hinge device of a mobile terminal. More specifically, by selecting a cam profile with an asymmetric structure, the selection range of the rotation angle can be widened. Background technique [0002] FIG. 1 is a perspective view of an existing mobile terminal. As shown in the figure, the mobile terminal is connected with a lower flip cover 21 and an upper flip cover 11 that can move relative to each other. [0003] A vertical hinge part 25 is provided on the upper edge of the lower flip cover 21, through which the vertical hinge part 25 can ensure that the upper flip cover 11 rotates in a direction parallel to the plate surface of the lower flip cover 21 with the hinge axis as the center, wherein, The installation direction of the hinge shaft is balanced with the thickness direction of the lower flip cover 21; and a horizontal hinge portion 31 is provided between the upper flip cover 11 and the vertical hinge portion 25, thro...
