Abstract

The invention discloses an automobile side box-division battery replacing device. The device comprises a plurality of box bodies; the multiple box bodies are arranged on the two sides of the central axis of an automobile body; the bottom of each box body is connected with an automobile bottom cross beam; a box cover is arranged on the side surface, close to the side skirt, of each box body; one end of each box cover is rotationally connected with the corresponding box body, and the other end of each box cover is connected with the box body through a locking mechanism; a plurality of first limiting blocks are arranged on the side surface of each box cover, the first limiting blocks are used for fixing the end surfaces of single batteries; and at least one first limiting plate is arranged inthe bottom surface of each box body and used for separating and fixing the single batteries. The automobile side box-division battery replacing device is simple in structure, light, handy and convenient, can meet the requirements of quick battery replacement under special equipment and bare-handed quick battery replacement without equipment, can place a battery at a safe position by bare hands when an automobile is parked for a long time, reduces the risk of spontaneous combustion and spontaneous explosion of the automobile, and improves the safety.

Description

technical field [0001] The invention belongs to the field of battery systems of new energy electric vehicles, and in particular relates to a car side compartment battery exchange device and an electric vehicle. Background technique [0002] At present, under the background of energy constraints and environmental pollution, the Chinese government regards the development of new energy vehicles as a major measure to solve energy and environmental problems and achieve sustainable development. Automobile manufacturers also regard new energy vehicles as the commanding heights of the future automobile industry. important strategic direction. With the joint efforts of the government and enterprises, my country's new energy vehicle industry has shown a good momentum of development in recent years. For new energy vehicles, its battery is one of the important components, and because the car will be affected by bumps and other impacts during driving, this requires higher requirements f...
