[0025] In another embodiment, the first telescopic rod 5 and the second telescopic rod 6 each include an outer rod 10 and an inner rod 11. The outer rod 10 is sleeved on one end of the inner rod 11, and the inner rod 11 is located at the end of the outer rod 10 away from the fixed rod 1. The outer rod 10 and the inner rod 11 have hollow structures. The hollow structures of the outer rod 10 and the inner rod 11 reduce weight and improve telescopic flexibility.

[0026] In another embodiment, a locking rod 12 extends through the inner rod 11. One end of the locking rod 12, located inside the inner rod 11, is fixedly connected to a limit plate 13. A spring 14 is sleeved on the outer surface of the locking rod 12, located between the limit plate 13 and the inner wall of the inner rod 11. One end of the spring 14 is fixedly connected to the limit plate 13, and the other end of the spring 14 is fixedly connected to the inner rod 11. A locking hole 15 is formed on the outer rod 10 to accommodate the locking rod 12. When the inner rod 11 is extended or retracted to the appropriate position, the locking rod 12 can be inserted into the locking hole 15, and the elastic force of the spring 14 locks the relative position of the inner rod 11 and the outer rod 10.

[0027] In another embodiment, the mobile rack 9 includes a connecting shaft 16, which is mounted on the top of the support rod 8. A tow bar 17 is fixedly connected to the connecting shaft 16. An angle limiting plate 18 is symmetrically provided on the top of the support rod 8. The angle limiting plate 18 is used to limit the angle of the tow bar 17. The angle limiting plates 18 are symmetrically provided on the top of the support rod 8 to limit the angle of the tow bar 17 to prevent the goods from sliding.

[0028] In another embodiment, the first telescopic rod 5 and the second telescopic rod 6 have the same length, and the first telescopic rod 5 and the second telescopic rod 6 are arranged parallel to each other.

[0029] In another embodiment, a limiting sleeve 19 is slidably connected to the fixed rod 1, and the limiting sleeve 19 is provided with a sliding groove 20 adapted to the shape of the outer rod 10. By adjusting the position of the limiting sleeve 19, the folding angle of the folding assembly 4 can be limited to meet different usage requirements.

[0030] Working principle: The fixing rod 1 is fixed to the rear seat of the motorcycle to support the entire rear rack. The fixing rod 1 is provided with a fixing bracket 2 for fixing other components, and the fixing rod 1 is provided with a connecting piece 3 for connecting to the motorcycle body.

[0031] During normal use, the outer rod 10 and the inner rod 11 are shortened and folded, and then the outer rod 10 and the fixed rod 1 are kept at the same horizontal plane, and then the limit sleeve 19 is pulled to fix the outer rod 10 and the fixed rod 1 together, and then the tow bar 17 on the mobile shelf 9 is rotated to the fixed bracket 2, which can be used to load goods or luggage, so that the rear shelf can be completely folded, saving space, and improving the aesthetics and riding experience of the motorcycle.

[0032] During long-distance travel, the folding state of the folding assembly is released by adjusting the position of the limit sleeve 19. By unfolding the first telescopic rod 5 and the second telescopic rod 6, the locking rod 12 is first pressed so that the locking rod 12 enters the inside of the outer rod 10, and then moves with the movement of the inner rod 11 until the first telescopic rod 5 and the second telescopic rod 6 are fully unfolded. The locking rod 12 will find the appropriate lock hole 15 under the action of the spring 14 and re-lock. Since the support rod 8 and the fixed rod 1 are connected by the first telescopic rod 5 and the second telescopic rod 6, and the first telescopic rod 5 and the second telescopic rod 6 are the same length and parallel, a parallelogram structure is formed. The support rod 8 is pulled downward until the first telescopic rod 5 is perpendicular to the fixed rod 1, and the tow rod 17 is rotated outward, thereby unfolding the mobile bracket and putting the mobile shelf 9 into use for loading goods or luggage, increasing the carrying capacity of the rear shelf, and meeting the loading needs of large quantities of goods.
