[0025] Please refer to Figures 1-4 The present application provides a sliding rail rocking wheel structure, which comprises an upper guide rail 1, a rocking wheel 2 and a support force arm 3. The support force arm 3 is installed on the guide rail 1 and can swing, and the rocking wheel 2 is connected with the support force arm 3. The support force arm 3 is installed on the upper guide rail 1 like a lever, and a longer force arm is used to provide a larger torque for the swinging of the rocking wheel 2, so as to enhance the stability.

[0026] It should be noted that please refer to Figure 5 The upper guide rail 1 of the present application is arranged on a sliding platform, and a fixed platform is arranged below the upper guide rail 1. The fixed platform has a lower guide rail corresponding to the upper guide rail 1. The sliding platform and the fixed platform are used to form a central armrest box of a car, and are made into a mobile intermediate grade to adapt to the adjustment and use of automatic and intelligent cars. Figure 5 The frame structure composed of the sliding platform and the fixed platform is shown.

[0027] The lower guide rail is the sliding rail of the present application.

[0028] Further, the rocking wheel 2 of the upper guide rail 1 will move in the lower guide rail and contact the inner wall of the lower guide rail. Due to the deviation of the upper guide rail 1 and the lower guide rail during the movement, the rocking wheel 2 connected with the support force arm 3 can be self-adaptively adjusted to contact the lower guide rail.

[0029] In the embodiment of the present application, the upper guide rail 1 is configured as a structure with a cavity, the support force arm 3 is installed in the cavity, and the support force arm 3 is rotationally connected with the upper guide rail 1 in the cavity from a position close to the middle part. The middle upper guide rail 1 has a limiting slot 5 in communication with the cavity at the side edge, the rocking wheel 2 is installed at the side edge of the middle upper guide rail 1, the main shaft in the middle part of the rocking wheel 2 passes through the limiting slot 5 and is then fixedly connected with one end of the support force arm 3, and the other end of the support force arm 3 is connected with the elastic structure 4. The elastic structure 4 supports the support force arm 3 stably and provides a restoring force for the swing of the support force arm 3, that is, the rocking wheel 2 is swung.

[0030] In the embodiment of the present application, the elastic structure 4 is composed of a hook 41 and a spring, i.e., an elastic member 42. The spring is installed at the end of the support force arm 3, and the hook 41 is arranged at the side edge of the support force arm 3. A little external force needs to be applied when the spring is hung on the hook 41, so that the rocking wheel 2 can be in close contact with the lower guide rail when the upper guide rail is combined with the lower guide rail, and the rocking wheel 2 can still be in contact with the lower guide rail even if there is swing when the upper guide rail moves next.

[0031] In the embodiment of the present application, the elastic structure 4 is composed of a hook 41 and a spring, i.e., an elastic member 42. The spring is installed at the end of the support force arm 3, and the hook 41 is arranged at the side edge of the support force arm 3. A little external force needs to be applied when the spring is hung on the hook 41, so that the rocking wheel 2 can be in close contact with the lower guide rail when the upper guide rail is combined with the lower guide rail, and the rocking wheel 2 can still be in contact with the lower guide rail even if there is swing when the upper guide rail moves next.
