Description

Active early warning explosion-proof box, battery and electric two-wheeled vehicle Technical Field The application relates to the field of two-wheelers, in particular to an active early warning explosion-proof box, a battery and an electric two-wheeler. Background In the use process of the battery, once the battery core is subjected to abnormal conditions such as internal short circuit, thermal runaway and the like, the air pressure in the shell can rise rapidly. When the air pressure exceeds the maximum pressure borne by the shell, the shell may crack or even explode, and the normal operation and personal safety of the equipment are seriously threatened. Therefore, the problem of air pressure rise caused by abnormal battery cells and even explosion is effectively solved, and the problem of safety and reliability of battery products are considered as a key problem to be solved in the technical field of batteries. Disclosure of utility model The application aims to provide an active early warning explosion-proof box, a battery and an electric two-wheeled vehicle, which have a good explosion-proof effect. An embodiment of the first aspect of the present application provides an active early warning explosion-proof box, including: The top end of the shell is provided with an opening; The cover body is provided with a first side and a second side which are opposite, the first side is hinged to one side of the top end of the shell, the second side is connected with an elastic belt, the bottom end of the elastic belt is detachably connected with the other side of the top end of the shell, and the cover body is provided with a side plate which is attached to the outer side face of the shell; The control unit is arranged in the shell; The air pressure detection unit is electrically connected with the control unit, is arranged in the shell and is used for detecting the air pressure in the shell. An embodiment of a second aspect of the present application provides a battery, including the active early warning explosion-proof case according to the embodiment of the first aspect. An embodiment of a third aspect of the present application provides an electric two-wheeled vehicle, including the battery according to the embodiment of the second aspect.
