Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 , the utility model provides two technical solutions:

[0021] Embodiment 1

[0022] A spare tire rear bracket comprises an outer shell 1, a viewing window 101 is fixedly connected to one side of the outer shell 1, a moving mechanism 2 is arranged at the bottom end of the inner part of the outer shell 1, a main frame 3 is arranged at the top of the moving mechanism 2, a rotating mechanism 4 is arranged at the middle position of the inner part of the main frame 3, and limiting mechanisms 5 are evenly arranged at equal distances on one side of the main frame 3. The storage situation of the spare tire inside the outer shell 1 can be conveniently observed through the viewing window 101, and a mounting piece is arranged inside the outer shell 1 to facilitate installation at the rear end of a car.

When the servo motor 201 is started, it can drive the threaded rod 202 to rotate. At this time, the threaded block 203 on the threaded rod 202 can move freely on the threaded rod 202, and the threaded block 203 can drive the main frame 3 to move inside the outer shell 1 through the first connecting block 204.

[0024] Embodiment 2

[0025] The main difference from the first embodiment is:

[0026] A spare tire rear bracket, the rotating mechanism 4 includes a turning handle 401 rotatably connected to the middle position of one side of the main frame 3, a winding roller 402 rotating inside the main frame 3 is fixedly connected to the middle position of one side of the turning handle 401, and a pull rope 403 is evenly and evenly fixedly connected to the outside of the winding roller 402. Rotation of the turning handle 401 can drive the winding roller 402 to rotate inside the main frame 3. At this time, the winding roller 402 can move by pulling a slider 6 through the pull rope 403, and the slider 6 drives the fixed arm 7 to move.

[0027] The limiting mechanism 5 includes sliders 6 which are evenly arranged at equal distances inside the main frame 3. The main frame 3 and the slider 6 are slidably connected. A pull rope 403 is fixedly connected to one side of the slider 6, and a spring 601 is fixedly connected to one side of the slider 6. A second connecting block 602 is fixedly connected to one side of the slider 6, and a fixed arm 7 is fixedly connected to one side of the second connecting block 602. When the slider 6 moves, the spring 601 on one side can be squeezed and the fixed arm 7 can be driven to move. When the pull rope 403 stops pulling the slider 6, the fixed arm 7 can be pushed to reset by the slider 6 due to the reaction force of the squeezed spring 601. At the same time, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0028] When the embodiment of the present application is in use: the main frame 3 can be driven to extend from the inside of the outer shell 1 by starting the moving mechanism 2. At this time, the turning handle 401 on the main frame 3 is turned, and the turning handle 401 drives the winding roller 402 to rotate, so that the winding roller 402 can be moved by pulling the slider 6 through the pull rope 403. When the slider 6 drives the fixed arm 7 to move, the spring 601 on one side can be squeezed. At the same time, the spare tire can be placed on the outside of the multiple sets of fixed arms 7, and the turning handle 401 is released. At this time, due to the reaction force of the squeezed spring 601, the fixed arm 7 can be pushed by the slider 6 to complete the limiting work of the spare tire, and the main frame 3 can be driven by the moving mechanism 2 to be retracted into the inside of the outer shell 1, so that the spare tire can be stored inside the outer shell 1 for subsequent use.
