[0038] When assembling the rotating shaft assembly:

[0039] First, the torsion pin shaft and the slider are positioned and assembled through the cooperation of the flat position;

[0040] Then one end of the torsion sheet is pressed and fitted with the torsion pin shaft installed on the sliding block, and the other end of the torsion sheet is assembled with the sliding pin shaft;

[0041] Finally, the sliding block is screwed into the base, the sliding pin shaft is installed into the base, and finally the base is connected as a whole.

[0042] The assembled rotating shaft assembly is installed into the mounting groove of the tablet computer body, and then the sliding block of the rotating shaft assembly is connected with the support, so that the sliding block of the rotating shaft assembly is driven to rotate by the support to realize the support of the support to the tablet computer body when the support is opened or the support is closed and the support is attached to the tablet computer body;

[0044] During the rotation of the support and the sliding block rotating with the support from the 0° position to a certain angle (such as 15°), the circumferential surface of the torsion pin shaft gradually rotates to the plane side wall of the holding area, so that the mutual interference area between the torsion pin shaft and the plane side wall of the holding area gradually increases until the tangent plane on the torsion pin shaft is completely turned out of the plane side wall of the holding area, and the torsion generated by the torsion sheet gradually increases to form a torsion climbing stage.

[0045] During the rotation of the support and the sliding block rotating with the support from a certain angle (such as 15°) to another angle (such as 57°), the mutual interference area between the circumferential surface of the torsion pin shaft and the plane side wall of the holding area remains stable, and the torsion generated by the torsion sheet is constant.

[0046] Correspondingly, during the closing process of the support and the sliding block rotating with the support, it will first go through the constant torsion stage, and then the torsion gradually decreases until the tangent plane on the torsion pin shaft is completely opposite to the plane side wall of the holding area on the torsion sheet, and there is no mutual interference between them.

[0047] When the above-mentioned self-locking support tablet computer is used, the rotation switching of the support in different use scenarios is improved, the convenience of using the tablet computer is improved, and through the cooperation between the torsion sheet and the torsion pin shaft, self-locking can be realized when the support is closed to avoid unnecessary opening of the support, stable torsion can be provided during the support of the support to ensure the stability of the support during repeated use, and the consistency of wear and tear during forward and reverse rotation is ensured, further optimizing the stability and smoothness of use.

[0048] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and to implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
