[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0028] Please see Figure 1-4 A stabilizing device for a motorcycle sidecar includes a side bracket 1. The side bracket 1 serves as the basic structure supporting the sidecar, capable of bearing the weight of the sidecar and passenger, and ensuring stability during operation. A protective frame 2 is inclined upward at the front end of the side bracket 1, which serves a protective function, reducing injury to the sidecar and passenger in the event of a collision or fall.

[0029] An extension rod 9 is provided on the inner side of the rear end of the side bracket 1. The top of the extension rod 9 is rotatably connected to a first tie rod 3 and a second tie rod 4, respectively. The top of the second tie rod 4 is rotatably connected to the outer wall of the first tie rod 3. Multiple third tie rods 5 are fixed on the inner side of the side bracket 1. The top of the third tie rods 5 is rotatably connected to a fourth tie rod 6. The ends of the first tie rods 3, third tie rods 5, and fourth tie rods 6 that are away from the side bracket 1 are all connected to the motorcycle frame, forming a triangular connection structure. The cooperation of the first tie rods 3 and second tie rods 4, as well as the third tie rods 5 and fourth tie rods 6, forms a triangular connection structure. Since one end of each tie rod is connected to the motorcycle frame, the triangular connection structure enhances the connection strength between the side bracket and the motorcycle frame, improves overall stability, reduces swaying during riding, and improves riding comfort and safety.

[0030] Multiple reinforcing rods 7 are fixed inside the side bracket 1. The reinforcing rods 7 enhance the overall structural strength of the side bracket 1, enabling it to withstand greater loads and stresses.

[0031] The reinforcing rod 7 is equipped with multiple fixing ears 8 for installing the side bucket. The fixing ears 8 serve as the connection points between the side bucket and the side bracket 1, making the installation of the side bucket more convenient and quick, and reducing the installation difficulty.

[0032] The third tie rod 5 includes a first threaded sleeve 501, one end of which is fixedly connected to the side bracket 1, and the other end of which is threadedly connected to a first threaded rod 502. One end of the first threaded rod 502 is fixed with a first connector 504 for connection to the motorcycle frame. The length of the third tie rod 5 can be finely adjusted to adapt to the installation requirements of different motorcycle models and frames. It can also be adjusted as needed during long-term use due to wear or deformation to ensure the stability of the connection and the smoothness of the sidecar.

[0033] A first locking nut 503 is threaded onto the outer surface of the first threaded rod 502. The first locking nut 503 abuts against the first threaded sleeve 501, and serves to lock and fix the rod, ensuring that the first threaded rod 502 will not loosen due to vibration after being adjusted to the appropriate position.

[0034] An L-shaped reinforcing rod 505 is fixed to the outside of the first threaded sleeve 501. One end of the reinforcing rod 505 is fixedly connected to the side bracket 1, which improves the structural strength of the first threaded sleeve 501.

[0035] The first tie rod 3, the second tie rod 4, and the fourth tie rod 6 have the same structure, each including a second threaded rod 601 and a third threaded rod 602. The outer threads of the second threaded rod 601 and the third threaded rod 602 have opposite directions. The outer threads of the second threaded rod 601 and the third threaded rod 602 are fitted with second threaded sleeves 603. The opposite ends of the second threaded rod 601 and the third threaded rod 602 are fixed with second connectors 604, which can finely adjust the length of the first tie rod 3, the second tie rod 4, and the fourth tie rod 6 to adapt to the installation requirements of different vehicle models and motorcycle frames.

[0036] The outer surfaces of the second threaded rod 601 and the third threaded rod 602 are threaded with a second locking nut 605. The inner side of the second locking nut 605 abuts against the second threaded sleeve 603, and the second locking nut 605 plays the role of locking and fixing.

[0037] The top end of the second threaded sleeve 603 on the first tie rod 3 is inclined outward, which makes it easier for the top end of the second threaded sleeve 603 to connect with the motorcycle frame, and makes the first tie rod 3 and the second tie rod 4 form a stable triangular connection structure.

[0038] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
