New energy automobile battery box

Abstract

The invention provides a new energy automobile battery box, which can effectively solve the problems of battery fixation and energy absorption in an emergency state; the solved technical scheme is asfollows: the new energy automobile battery box comprises a first rectangular box, a second rectangular box is arranged in the rectangular box, a third rectangular box is arranged in the second rectangular box, vertical plates are arranged on the surroundings of the third rectangular box, a longitudinal plate is arranged at one end of each vertical plate, the longitudinal plate and the vertical plate form an L-shaped plate, the third rectangular box and the second rectangular box are provided with pressure springs, a rectangular block is arranged between two third rectangular boxes, latch pinsare uniformly distributed on the rectangular block, a cylinder is arranged on the third rectangular box, vertical plates are arranged on the left and right sides of the rectangular block, connecting rods are arranged on the front and back sides of the vertical plates, and the other ends of the connecting rods are hinged with the vertical plates in the corresponding L-shaped plates; and the new energy automobile battery box provided by the invention are smart in structure and are simple and easy to use, solves the problem of conflict between the fixing and buffering of a battery, and realizes the fixing of the battery when the stress is relatively small and the buffering of the battery when the stress is relatively large, the buffering process is stable, large and small impacts can be effectively buffered, so that the safety of the battery is greatly ensured, and accordingly, the new energy automobile battery box is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a battery box of a new energy vehicle. Background technique [0002] At present, the power battery box of pure electric vehicles on the market is mainly arranged under the chassis, and the structure of the battery box is mostly rectangular and has no protective measures. Most of the current methods simply fix the battery or allow the battery to slide, so that the energy-absorbing material absorbs the buffer force. However, when the vehicle shakes slightly, the vehicle's own shock absorption can fully guarantee the safety of the battery. It is necessary to make additional sliding of the battery, thereby increasing unnecessary wear and battery sliding; when the vehicle collides at an excessive speed or brakes in an emergency, a large collision force will be generated. Excessive collision force will cause damage to the battery box or even the power battery. fire, explosio...
