DETACHMENT STRUCTURE OF A POWER-ASSISTING BATTERY

A detachment structure of a power-assisting battery, applicable to a cart, includes a support module, two motor wheel sets, and a battery module. The support module includes two structurally identical supports. One end of each support has a raised element and a dented element. The supports are fitted together because the raised elements engage with the dented elements. Each motor wheel set has an axle and a quick-release transmission connector. The battery module includes a battery holder, driver unit, and replaceable battery. The battery holder has a receiving chamber, waterproof cover, and fixing component. The driver unit includes a driver and a signal port. The battery is disposed in the receiving chamber and has a grip whereby the battery can be pulled by a user. The driver and the battery holder are integrated into the battery module. The fixing component allows the waterproof cover to be locked and unlocked.
