Battery and electric vehicle holder

Abstract

The invention relates to an electric transmission device, an electric vehicle, and a method for installing an electric transmission device. A battery holder is mounted on the body of an electric vehicle to secure the battery pack. The battery holder comprises a fixed frame, a locking mechanism, and a large number of supporting devices. The locking mechanism is fixed to the fixed frame. The supporting devices are fixed on one side of the fixed frame opposite the battery pack. Numerous supporting devices are used to provide multiple support points for holding the battery pack. The electric vehicle includes a battery holder as described above. In the battery and electric vehicle mounting bracket, which are included in the same invention, the weight of the battery pack can be distributed simultaneously across multiple support devices and locking mechanisms. The force on the fixed frame is more evenly distributed, the force exerted by the battery pack on the locking mechanism is reduced, the concentration of force of the locking mechanism on the fixed frame is prevented, the lifespan of the locking mechanism is improved, and the safety performance and connection strength between the battery pack and the battery mounting bracket are enhanced.
