Wheel, luggage box and trolley with braking function

[0032] The present invention provides a wheel with a braking function, including a fixed seat 7 and a universal wheel, the universal wheel is rotatably connected to the fixed seat 7, and the universal wheel is provided with an induction device, a signal processing module 6 and a braking device, The sensing device senses an external signal, the signal processing module 6 receives the external signal sensed by the sensing device, the signal processing module receives the external signal sensed by the sensing device, and controls the brake device to drive the locking and movement of the universal wheel . The braking device can be a braking structure inside the wheel that directly brakes the rotating shaft of the universal wheel, or a micro-motor and a planetary gear that brake the hub of the universal wheel through a worm gear structure.

[0033] Such as figure 1 , 2 As shown, the first embodiment provided by the present invention includes a fixed seat and a universal wheel, the u

[0037] Such as image 3 , 4 As shown, it is a schematic diagram of Embodiment 2 provided by the present invention, and its difference from Embodiment 1 lies in the braking device. The brake device includes a four-bar linkage mechanism 14 and a power linkage 13 , and the signal processing module 6 controls the four-bar linkage mechanism 14 through the power linkage 13 to drive the hub 12 of the universal wheel to lock or rotate. Specifically, such as figure 1 , 2As shown, the brake device in Embodiment 1 provided by the present invention includes a four-bar linkage mechanism 14. After the signal processing module 6 receives the brake signal, it controls the four-bar linkage mechanism 14 through the power linkage 13 to perform braking. Move, block the wheel hub 12 of the universal wheel. The four-bar linkage mechanism 14 can expand and contract along both sides, and brake the hubs 12 on both sides of the universal wheel to prevent the braking failure of the hub on one side. Th

[0039] Such as Figure 5 , 6 Shown is Embodiment 3 provided by the present invention. A wheel with a braking function, comprising a fixed seat 7 and a universal wheel, the universal wheel is rotatably connected to the fixed seat 7, the universal wheel is provided with an induction device, a signal processing module 6 and a braking device, the The sensing device senses an external signal. The brake device includes an electromagnet brake lever 17 and a brake battery 18 . The electromagnet brake lever 17 includes a rod body, a first extension part 21 and a second extension part 22, and the signal processing module 6 drives the first extension part 21 and the second extension part 22 of the electromagnet brake lever 17 from The rod expands and contracts in the body to realize the clamping and releasing of the hub 12.

[0040] In this embodiment, the signal processing module 6 is selected as the wireless signal processing module 16, and there is no need to extend the wires of the
