The invention provides a braking mechanism of a cart, a driving part of the braking mechanism and the cart, the driving part is arranged in the braking mechanism to be capable of moving between a locking position and an unlocking position so that the braking mechanism can lock or unlock wheels of the cart, the driving part is provided with a guide side face, a guide groove is formed in the guide side face, and the guide groove comprises a stop groove; the brake mechanism is further provided with a brake part, the stop end of the brake part is arranged to move in the guide groove, and the drive part moves to the locking position in the locking direction, and the stop end moves to the stop groove in the guide groove in the first direction and stays at the position of the stop groove. The stop groove is provided with a buffer part, the buffer part is arranged to elastically prevent the stop end from moving away from the stop groove in the second direction, and the second direction is opposite to the first direction. According to the vehicle wheel unlocking device and method, even if a user accidentally operates mistakenly in the unlocking process, the driving piece can return to the unlocking position, and the vehicle wheel is unlocked.

    本公开提供了一种推车的制动机构、制动机构的驱动件和推车,其中驱动件在制动机构中设置成能够在锁定位置与释锁位置之间运动,以使制动机构锁定或释锁推车的车轮,其中,驱动件具有引导侧面,其设有引导槽,所述引导槽包括止动槽;其中,制动机构还设有制动件,其止动端设置成在引导槽中移动,通过使驱动件朝锁定方向运动到锁定位置,止动端在引导槽中沿第一方向移动到止动槽并停留在止动槽处;其中,止动槽设有缓冲件,缓冲件设置成弹性阻挡止动端沿第二方向移离止动槽,其中,第二方向与第一方向相反。根据本公开,即使用户在释锁过程中不小心发生误操作,驱动件也能够回到释锁位置而使车轮被释锁。
