Background

The new energy automobile refers to an automobile which adopts unconventional automobile fuel as a power source. Its driving energy source includes hydrogen energy, pure electric power or hybrid power. The new energy automobile can reduce the emission of greenhouse gases and has no noise during operation. However, the cost is too high, and the production process also consumes a large amount of electric energy and water. The existing new energy automobile battery has low energy density and short driving mileage. Since a charging station applied to an automobile has not been widely used yet, and a situation where charging cannot be performed without electric power during traveling may occur, a measure generally taken is to carry a backup battery.

However, in the actual battery replacement process, the personnel need to bend down to the position where the automobile chassis is parallel to each other and pull out the battery from the battery compartment of the chassis, and the process is time-consuming and labor-consuming and needs other tools due to the narrow space of the automobile chassis; in addition, because the automobile battery is faster to update, and the automobile itself can have a service life of several years, the size and shape of the battery of the new generation may be different from those of the old, and after the automobile which is purchased and used for a period of time loses the new battery, the original battery locking device may not achieve the locking effect; in order to maintain the data memory function, electrical equipment of the new energy automobile, such as an air conditioner, a sound and the like, must be supplied with power all the time, so that the storage battery always has quiescent current. In order to ensure that one vehicle can still be normally started after standing for three months, the quiescent current of the whole vehicle needs to be below 10 ma. If the storage battery has a fault, the automobile can be possibly started after being stored for a long time due to overlarge quiescent current, a microammeter or a special direct-current power consumption tester is usually adopted for quiescent current testing, the battery needs to be taken out in the testing process, and the battery state cannot be monitored at any time, so that potential safety hazards can be caused. Therefore, it is necessary to design a new energy automobile battery locking device which is convenient for loading and unloading batteries, suitable for batteries with different sizes and capable of preventing electric leakage.
