Detailed ways

Refer to the attached drawings. The hinge provided by the present invention comprises a mounting frame 1 and a rotating assembly. The rotating assembly is rotatably mounted on the mounting frame 1. The rotating assembly has a virtual center O as an axis, and the virtual center O is outside the rotating assembly. Greatly reduce the thickness of the hinge.

The rotating assembly is coupled to the elastic mechanism by a fixed shaft 2 at a position offset from the axis, the fixed shaft 2 being fixed to the rotating assembly connected thereto, and the first end of the elastic mechanism is provided with a winding circle 31, The winding circle 31 clamps the fixed shaft 2, the first end of the elastic mechanism rotates with the rotating assembly, and the second end 32 of the elastic mechanism is restrained by the groove 4 to perform a circular motion at the first end. The slot 4 moves. Thereby, the elastic mechanism itself swings around the second end, and at the same time, the fixed shaft 2 and the winding circle 31 are relatively rotationally rubbed, and the function of stopping the rotation at any time is provided, so that the rotating component can stably stay at any one. The angle of rotation.

As shown in the figure, in the present embodiment, the groove 4 is a linear groove whose position is biased toward the other side of the position where the fixed shaft 2 is located when the hinge is closed (Fig. 4), so that it can be obtained as the angle of rotation increases. The increasing rotational resistance has a better operating feel, and the cooperation of the groove 4 and the elastic mechanism functions to amplify the force value. By changing the shape and position of the groove 4, other adjustment effects and corresponding hand feelings can be obtained.

In order to further reduce the thickness and obtain a larger opening angle, the rotating assembly is constituted by the first component 41 and the second component 42 which are slidably connected, the fixed shaft 2 and the first component 41 are fixedly connected, and the first component 41 and the second component 42 are passed The circular arc-shaped slider 411 and the circular-arc track 421 are slidably coupled with each other, and the second component 42 and the mounting frame 1 are engaged by the circular arc-shaped slider 422 and the circular-arc track 11 therebetween. The first component 41 and the second component 42 are overlapped by sliding connection and with the hinge in a closed state. A constrained structure is further disposed between the first component 41 and the second component 42. The limiting structure includes a stopper 423 disposed on the second component and a stopper 413 on the first component, when the hinge is opened, First, the first component 41 rotates. When the first component 41 is turned to a certain angle, the stopper 413 and the stopper 423 collide, and the second component 42 is driven to continue to rotate until the maximum opening angle is reached.

The elastic mechanism is formed by the reed 3. The reed is provided with a rotation angle limiting structure 33 of the rotating assembly to define a maximum opening angle of the hinge. When the gear 412 on the rotating assembly collides with the rotation angle limiting structure 33, the hinge opens to a maximum angle.

The second end 32 is connected to the sliding shaft 5, and the sliding shaft 5 is slidably coupled to the groove 4 so that the second end can only be restrained by moving along the groove 4.

The mounting bracket 1 and the rotating assembly are respectively provided with

mounting positions

10, 40 for connection with the mobile digital product to which the hinge is applied. As shown in FIG. 7, the present invention can be used as a hinge for the bracket in the tablet computer. One of the mounting bracket and the rotating assembly is coupled to the tablet body 101, and the other of the mounting bracket and the rotating assembly is coupled to the bracket 102.

The above description is only the specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the scope of the present invention.
