[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model. The structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the limited conditions for the implementation of the present utility model. Therefore, they do not have technical essential significance. Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the effects that the present utility model can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle", etc. cited in this specification are only for the convenience of description and are not used to limit the scope of implementation. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope that the present utility model can implement.
[0020] Please refer to Figure 1 and Figure 3, An automotive seat turntable, comprising a lower disc assembly 1, a lower cage 2, an upper cage 3 and an upper disc assembly 4. The upper cage 3 and the lower cage 2, as well as the upper cage 3 and the upper disc assembly 4, are movably connected by balls. Conventional connection methods are adopted among the lower disc assembly 1, the lower cage 2, the upper cage 3, the upper disc assembly 4 and the balls. In particular, the structures in the patents previously applied by the applicant can be selected, which will not be elaborated here.
[0021] Locking grooves 5 are spaced circumferentially on the upper cage 3. A switch assembly 6 is provided on the upper disc assembly 4. The switch assembly 6 includes a rotatable rod body 61. A locking tongue 62 that cooperates with the locking groove 5 is provided on the rod body 61. A torsion spring 63 is sleeved at the end of the rod body 61. The locking groove 5 is a toothed groove, and the front end of the locking tongue 62 is a toothed structure. The locking of the upper cage 3 can be achieved through the cooperation of the locking groove 5 and the locking tongue 62. By adjusting the number of toothed grooves, the minimum rotation angle of the upper cage 3 can be 10°.
[0022] One end of the torsion spring 63 is fixed on the rod body 61, and the other end is fixed on the upper disc assembly 4. A blind rivet 64 is fixedly connected to the rod body 61, and the blind rivet 64 presses one end of the torsion spring 63. By positioning the two ends of the torsion spring 63 through the blind rivet 64 and the upper disc assembly 4, the torsion spring 63 can provide a restoring force for the rod body 61, ensuring that the rod body 61 can quickly and accurately return after unlocking, and at the same time providing a locking force to prevent the locking tongue from disengaging from the locking groove.
[0023] An elastic cylindrical pin 65 is provided on the rod body 61. The elastic cylindrical pin 65 is located on one side of the locking tongue 62 and abuts against the locking tongue 62. The locking tongue 62 is positioned by the elastic cylindrical pin 65 to prevent the locking tongue from sliding on the rod body 61, avoiding affecting unlocking and locking, and ensuring the use reliability of the rotating seat.
[0024] In the initial position, the upper cage 3 is in a locked state, and the locking tongue 62 completely enters the locking groove 5. When unlocking is required, just rotate the rod body 61. The rod body 61 drives the locking tongue 62 to disengage from the locking groove 5. At this time, the upper cage 3 can rotate. When it rotates a certain angle, the upper cage 3 can stop. Release the rod body 61, and the torsion spring 63 drives the locking tongue 62 to reset. At this time, the locking tongue 62 enters the locking groove 5 again and enters the locked state.
[0025] Different from the prior art, the automotive seat turntable of the present utility model can simplify the structure of the locking switch, facilitate locking and unlocking, ensure that the locking groove and the locking tongue can be normally separated, and ensure that the seat can rotate normally.
[0026] The above has schematically described the present utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
