The connecting plate 33 and the second U-shaped frame 34 are rotatably connected to each other, so that the roller 35 can rotate at any angle in the horizontal direction, thereby achieving the effect of a universal wheel, and the rotating shaft 31 is fixedly connected to the first U-shaped frame 32, so when the rotating shaft 31 rotates, the first U-shaped frame 32 can be driven to rotate, thereby driving the roller 35 to flip and store. Example 2

[0022] like Figures 1 to 4 As shown, a driving mechanism 4 is installed inside the rectangular storage frame 2, and the driving mechanism 4 includes a third U-shaped frame 41 fixedly installed on the top of the rectangular storage frame 2, and a driving motor 42 is fixedly installed on the inner bottom of the third U-shaped frame 41. The output shaft of the driving motor 42 is fixedly connected to the first bevel gear 43, and a control switch 7 matched with the driving motor 42 is fixedly installed on one side of the upper surface of the luggage body 1. The operation of the driving motor 42 can be controlled by the control switch 7. The rotation of the driving motor 42 can drive the first bevel gear 43 to rotate, thereby driving the transmission mechanism 5 to rotate, and then automatically driving the pulley assembly 3 to flip, without manual operation, reducing the workload, thereby solving the problem that the existing luggage wheels need manual operation to realize the flipping of the wheels when in use, which increases the workload. Example 3

[0023] like Figures 1 to 4As shown, a transmission mechanism 5 matched with the pulley assembly 3 and the driving mechanism 4 is installed inside the rectangular storage frame 2, and the transmission mechanism 5 includes a first bearing seat 51 symmetrically fixedly installed on the top of the rectangular storage frame 2, and a first transmission shaft 52 is rotatably connected between the two first bearing seats 51, and the outer surface of the first transmission shaft 52 is fixedly sleeved with a second bevel gear 53 meshing with the first bevel gear 43, and both ends of the first transmission shaft 52 are fixedly connected with a third bevel gear 54. A second bearing seat 55 is fixedly connected to the inner top of the rectangular storage frame 2 and located above the first U-shaped frame 32, and a second transmission shaft 56 is rotatably connected to the bottom of the second bearing seat 55, and a fourth bevel gear 57 meshing with the third bevel gear 54 is fixedly sleeved on the outer surface of the second transmission shaft 56. A worm 58 is fixedly connected to the bottom end of the second transmission shaft 56, and a worm wheel 59 meshing with the worm 58 is fixedly sleeved on the outer surface of the rotating shaft 31.

[0024] The first bevel gear 43 rotates through the second bevel gear 53 to drive the first transmission shaft 52 and the two third bevel gears 54 to rotate. The third bevel gear 54 rotates through the fourth bevel gear 57 to simultaneously drive the second transmission shaft 56 and the worm 58 on both sides to rotate.

[0025] Working principle: When in use, the connecting plate 33 and the second U-shaped frame 34 are rotatably connected, so that the roller 35 can be rotated at any angle in the horizontal direction, thereby achieving the effect of a universal wheel. When the roller 35 needs to be stored, the drive motors 42 on both sides can be controlled by the control switch 7. The rotation of the drive motor 42 can drive the first bevel gear 43 to rotate, thereby driving the transmission mechanism 5 to rotate, and then automatically driving the pulley assembly 3 to flip, without manual operation, reducing the workload, thereby solving the problem that the existing luggage wheels need manual operation to realize the wheels when in use. In order to solve the problem of increasing the workload due to the flipping of the two pulley assemblies, the first bevel gear 43 rotates through the second bevel gear 53 to drive the first transmission shaft 52 and the two third bevel gears 54 to rotate. The third bevel gear 54 rotates through the fourth bevel gear 57 to simultaneously drive the second transmission shaft 56 and the worm 58 on both sides to rotate. Then, the rotating shaft 31 in the pulley assembly 3 can be driven to rotate through the worm gear 59, so that the two pulley assemblies 3 can be flipped at the same time without having to operate them separately, thereby improving the operating efficiency, thereby solving the problem that the existing luggage wheels need to operate the four movements and storage operations separately when in use, thereby reducing the efficiency.
