Rapid battery box release structure for electric vehicles

Abstract

The invention relates to a rapid battery box release structure for electric vehicles. The rapid battery box release structure comprises a battery box main body (1) containing a battery. The battery box main body (1) is placed on a locking and fixing structure (2) and a sliding guide structure (3), which play a positioning or guiding role when the battery box is installed or pulled out. The back side of the battery box main body (1) is provided with a water-electricity integrated fast change connector (4), which satisfies energy and signal transmission required by the battery box and connectionof a cooling system. According to the invention, the guide function of rapid release is realized through the sliding guide structure, the fixing function is realized through the locking and fixing structure of the battery box (containing the battery), and the energy and signal transmission of the battery box and the quick plugging function of the cooling system are realized through the water-electricity integrated fast change connector. Rapid release of the battery box is achieved. Meanwhile, the structure of the invention has advantages of simple operation, reliable connection and good system stability, and greatly facilitates daily maintenance and emergency disposal of the battery box (containing the battery).

Description

Technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to a quick release structure for a battery box for an electric vehicle. Background technique [0002] In recent years, the number of electric vehicles has increased. At present, most electric vehicle battery boxes (including batteries) are fixed by bolts. Once the battery has a problem, it is difficult for people to get close due to high temperature smoke and fire producing toxic gas. Even the whole vehicle was scrapped because of the battery box problem. At the same time, this installation method is not convenient for daily maintenance, so it is necessary to develop a battery box installation structure that can realize quick release. [0003] For example, the Chinese invention patent with publication number CN 107994178 A discloses an electric car battery box. The box body includes four side plates and a bottom plate. At least one of the four side plates is provided with a...
