Balance car battery with good protection mechanism

The invention belongs to the technical field of batteries, and discloses a balance car battery with a good protection mechanism, the balance car battery comprises a fixed plate, the top of the fixed plate is fixedly connected with a dust cover, the outer surface of the dust cover is movably sleeved with a buffer cover, and the top of the buffer cover is fixedly connected with a sealing cover through a bolt. Through a first spring, a guide sleeve plate, a stress plate and a second spring, firstly, under the support of a support plate, the first spring can integrally play a role in buffering the sealing cover and the buffer cover, so that damage caused by the fact that a heavy object directly impacts a battery in the dustproof cover is avoided; through cooperation of a guide sleeve plate and a guide plate, part of transverse impact borne by a stress plate can be weakened under the elastic force recovery effect of a second spring, meanwhile, transverse impact of the descending part of cooperation of the guide sl
