[0026] Specifically, threaded sleeve 11 is installed on the side wall of adjusting seat 8, threaded rod 10 is screw connected with threaded sleeve 11 and rotationally connected on longitudinal beam 1.When rotating threaded rod 10, due to the screwing of threaded sleeve 11 and threaded rod 10, threaded sleeve 11 will drive adjusting seat 8 to move along the length direction of transverse beam 3.Through controlling the number of rotation and direction of threaded rod 10, the position of adjusting seat 8 can be accurately adjusted, and then the position of threaded hole 9 is adjusted.

[0027] Please refer to Figure 4The inner part of the threaded sleeve 11 is integrally formed with internal threads, and the outer wall of the threaded rod 10 is provided with external threads matched with the internal threads.

[0028] Specifically, when the threaded rod 10 rotates, the helix angle of the threads converts the rotational movement of the threaded rod 10 into linear movement of the adjusting seat 8 along the length direction of the cross beam 3, thereby adjusting the position of the adjusting seat 8. The matched thread structure ensures the accuracy and stability of the thread transmission, making the movement of the adjusting seat 8 more stable and avoiding shaking or jamming.

[0029] Referring to Figure 3 and Figure 4 , the inner wall of the cross beam 3 is provided with a sliding rail 13 extending along the length direction thereof, and the side wall of the adjusting seat 8 is provided with a sliding groove 12, and the sliding rail 13 extends into the sliding groove 12.

[0037] Referring to Figure 1 , the transverse beam 3 is perpendicular to the side wall of the longitudinal beam 1, and the longitudinal beam 1 and the transverse beam 3 are connected by the threaded rod 10.

[0038] Specifically, the transverse beam 3 is perpendicular to the side wall of the longitudinal beam 1, forming a stable frame structure to provide basic load bearing and support function for the vehicle frame. The longitudinal beam 1 and the transverse beam 3 are connected by the threaded rod 10, which ensures the structural connection strength while realizing the adjustment of the mounting point position on the transverse beam 3 through the cooperation of the threaded rod 10 and the adjusting seat 8. The vertically arranged transverse beam 3 and longitudinal beam 1 form a stable vehicle frame structure, ensuring good structural strength and stability of the vehicle.

[0039] Working principle: The electric three-wheeled motorcycle integrated hollow stamping frame mainly realizes installation and adaptation through the adjustable structure on the transverse beam 3. Straight slots 7 are opened on the transverse beam 3, and adjusting seats 8 are slidably installed inside.

In the adjusting assembly, the threaded sleeve 11 is installed on the side wall of the adjusting seat 8, the threaded rod 10 is threadedly connected with the threaded sleeve 11 and rotationally connected on the longitudinal beam 1. By rotating the threaded rod 10, the adjusting seat 8 is driven to slide along the length direction of the transverse beam 3 through threaded transmission, so as to change the position of the threaded hole 9.

[0040] The slide rail 13 on the inner wall of the transverse beam 3 cooperates with the slide groove 12 on the side wall of the adjusting seat 8 to provide guidance and support for the sliding of the adjusting seat 8, ensuring the linearity and stability of the sliding. The counterbore 5 on the longitudinal beam 1 provides installation space for the threaded rod 10, and the shaft sleeve 6 is installed in the counterbore 5 to reduce the friction when the threaded rod 10 rotates and provide stable support. Four straight slots 7 and corresponding adjusting seats 8 are arranged symmetrically in pairs, providing multiple adjustable mounting points, which can be flexibly selected according to actual needs. The transverse beam 3 is perpendicular to the longitudinal beam 1 to form a frame structure, and the threaded rod 10 connects the two, which ensures the structural strength while realizing the adjustment of the mounting point. When the frame and the support, accessories are installed, if the mounting hole position deviates, the position of the adjusting seat 8 can be adjusted through the adjusting assembly, so that the threaded hole 9 is aligned with the mounting hole of the support and accessories, and then connected with the connecting piece.
