Title:
BRAKING DEVICE, WHEEL ASSEMBLY, AND WALKING AID
Document Type and Number:
WIPO Patent Application WO/2023/015733
Kind Code:
A1
Abstract:
The present application discloses a braking device, a wheel assembly, and a walking aid. The braking device comprises a shaft, a casing, a magnetic induction mechanism, and an adjustment mechanism. The casing is rotatable relative to the shaft; the magnetic induction mechanism is disposed in the casing and is configured to generate resistance, against the rotation direction of the casing or the shaft, to the casing or the shaft by means of a magnetic field reaction when the casing rotates relative to the shaft; the adjustment mechanism is connected to the magnetic induction mechanism and is configured to adjust the resistance. The provision of the magnetic induction mechanism to generate resistance can achieve braking of a wheel body integrated with or connected to the braking device, and because the braking force is related to the rotation of the casing or the shaft, rather than frictional braking, the sudden stop effect can be prevented, such that the safety is higher, the wear can be reduced, and the service life of the braking device is prolonged. In addition, the braking device has a simple structure and is easy to manufacture, and the provision of the adjustment mechanism to automatically adjust the resistance causes the braking device to be applicable in a wider range and be more intelligent.
