M264352 V. Creation Instructions (5) One of the bodies of the foldable mobile communication device is opened with a shape of a cam member 50, which has a hole with the same size and shape. The cam member 50 is installed in the hole. The outer contour is polygonal, so it cannot be rotated relative to the body. Also, one end of the cover of the folding mobile communication device is opened with a hole of the same size and shape as the outer contour of the housing 20. The housing 20 is installed in the hole. 20 has two cutting planes 201 for positioning, so it cannot rotate relative to the cover. In this way, the relative rotation of the folding mobile communication device body and the cover body is completely realized by the relative rotation of the cam member 50 of the hinge structure and the housing 20. When the folding mobile communication device with the hinge structure is used, an external force is applied to the cover of the folding mobile communication device, so that the housing 20 and the follower 40 are rotated, so that the follower 40 is raised. The portion 401 slides on the cam surface 503 of the cam member 50. Since the position of the cam member 50 is fixed, when the relative position of the convex portion 40 is changed, the follower 40 will generate an axial direction in the direction of compressing the elastic member 30. Move, and simultaneously drive the housing 20 and the cover to rotate together. See Figure 4A, the hinge structure is in the transition position during opening. When the projection 401 of the follower 40 reaches the top 5032 of the cam member or the apex of the sloping surface 5031, if the force applied to the cover is released, the elastic tension of the element 30 returns to the initial state. The sharp inclined surface 5′〇31 can overcome the rotation force of the cover body, so that the follower 40 can rotate back to its initial state in the opposite direction. Therefore, before the protruding portion 401 of the follower 40 completely passes the sharp inclined surface 5031, if the force applied to the cover body is removed, the cover body cannot be opened. When the follower 4〇 & starting portion 401 reaches the top 5032 of the cam member 50 or the apex of the sharp inclined surface 5031, when the gentle inclined surface 5033 is entered, even if the force applied to the cover is removed, the elasticity of the follower end The elastic tension of the το member 30 and the inclination of the gently inclined surface 503

Please refer to FIG. 4B together. When the protruding portion 401 of the follower 40 reaches the top of the cam member 5 0 5 0 3 2 or the apex of the sharp inclined surface 5 0 3 1, the raised portion 4 0 1 is along the gentle inclined surface 50 33 continues to slide. When the follower 40 and the cover rotate together, the elastic element 30 also gradually returns to its natural state, that is, when it reaches the valley 5 0 3 of the cam member 50, it stops sliding, and the valley 50 3 may Keep it stable in a stable state, that is, the fully opened state shown in Figure 4B. When the user closes the cover of the mobile communication device equipped with the hinge structure, the projection 401 of the follower 40 is pushed to slide on the cam surface 50 of the cam member 50. Since the cam member 50 cannot move, the follower member 40 moves in the direction of the compression elastic element 30, and drives the housing 20 and the cover body to rotate in the opposite direction to the aforementioned opening operation. Similar to the opening operation described above, when the convex portion 40 of the follower 40 passes through the slowly sloping surface 5 03 3. When the top portion 5 0 3 2 is at the steep slope 5 0 31, even if the force acting on the cover body is removed, because With the tension of the sharp inclined surface 503 and the elastic element 30, the cover body will automatically close. The hinge structure of this creation includes a housing 20 which is non-rotatable with the cover body. The entire hinge can be constituted as an independent component, which is integrally installed in the body of the foldable mobile communication device, which is convenient for installation and replacement. The body is not in direct contact, which can greatly reduce body wear. In addition, the vertical shaft 60 and the cam member 50 have a simple structure, which is convenient for processing and manufacturing.
