Battery bracket and power supply device

Abstract

The invention provides a battery bracket and a power supply device. The power supply device comprises a battery bracket and a battery module fixed on the battery bracket. Walking wheels are arranged on the battery bracket. A frame connecting structure and a lifting structure which is capable of adjusting the height of the battery bracket and used for keeping the frame connecting structure and a corresponding connecting structure on a vehicle at corresponding positions are further arranged on the battery bracket. With the walking wheels, the battery bracket is convenient to move; with the lifting structure, the height of the battery bracket can be adjusted, so that the frame connecting structure on the battery bracket is opposite to the corresponding connecting structure on the vehicle andthus the battery bracket is conveniently mounted on the vehicle; the power supply device can be firmly and reliably fixed on the vehicle, and the safety and reliability of the power supply device in the use process are further ensured; and the power supply device can be quickly mounted or dismounted relative to the vehicle, so that the power supply device is more convenient and quicker to use.

Description

technical field [0001] The invention relates to a battery bracket and a power supply device. Background technique [0002] Nowadays, electric trucks are increasingly favored by logistics companies and freight companies. However, due to the constraints of current battery technology, electric trucks have disadvantages such as small battery capacity and slow charging; this has caused the problem that electric trucks take a long time to charge during use, which seriously affects the work of users efficiency. [0003] In order not to affect the user's work efficiency, in the prior art, such as a Chinese utility model patent with the authorized announcement number CN206968379U discloses a battery pack that can be replaced quickly. The upper end is connected by a shaft, and a connecting block is arranged at the lower end of the hydraulic cylinder. The quick-change frame body is hooked with the connecting block through the hook angle on the connecting rod, so that the quick-change...

[0004] However, the quick-change frame and the battery pack on it are always hung on the hydraulic cylinder, so that the hydraulic cylinder is always pulled by the gravity of the battery and the quick-change frame during use, and the hydraulic cylinder is under stress for a long time and decreases. The service life of the hydraulic cylinder is shortened; and the quick-change frame is only hooked to the hydraulic cylinder. During the driving process of the vehicle, due to the bumpy road surface, the quick-change frame will vibrate or jump and be prone to decoupling. This will not only cause Damage to vehicle components may also cause traffic accidents
