The working process of the battery transferring device for transferring the battery pack to the battery replacing equipment or the battery rack is as follows: the battery pack is clamped by the two extending pieces from two sides of the battery pack, the two extending pieces are located in the battery accommodating bin, at this time, the battery accommodating bin is lifted in the vertical direction to adjust the height position, so that the battery accommodating bin can be matched with the battery bin of the battery replacement device or the battery rack in position, then the two extending pieces are driven to extend out of the battery accommodating bin from the two sides of the battery pack, along with the extending of the two extending pieces, the battery pack can be extended to the upper surface of the battery replacement device or the inner bottom surface of the battery bin, no structural barrier exists between the bottom of the battery pack and the upper surface of the battery replacement device or the inner bottom surface of the battery bin, then the battery pack is released from the two sides of the battery pack, the battery pack is directly flatly placed on the battery replacement device or the inner bottom of the battery bin, the bottom of the battery pack is abutted against the inner bottom of the battery bin of the battery replacement device or the battery rack, the battery pack is placed until the battery pack is completed, the two extending pieces are driven to shrink, and the two extending pieces can leave the battery replacement device or the battery rack along the two sides of the battery pack and return to the battery accommodating bin.

The two extending parts clamp the battery pack from the two sides of the battery pack and are horizontally placed on the battery Bao Ping, whether the battery transferring device takes the battery pack out of the battery exchange equipment or the battery rack or transfers the battery pack to the battery exchange equipment or the battery rack, the two extending parts and the battery pack are always in clamping states, so that the battery pack can always keep a preset direction and cannot deviate, and the interaction efficiency of the battery pack is improved. Meanwhile, as the extending piece clamps the battery pack from two sides of the battery pack, the bottom of the battery pack and the upper surface of the battery replacing equipment or the inner bottom surface of the battery bin can be provided with smaller distances, so that the acting force of the battery pack on the battery replacing equipment and the battery frame in the vertical direction can be conveniently controlled, and the impact of the weight of the battery pack on the battery replacing equipment and the battery frame is reduced.

Therefore, first, two protruding pieces of the battery transferring device can clamp the battery pack from two sides of the battery pack to transfer, the height space occupied by the clamping structure of the battery transferring device for clamping the battery pack is reduced, in the transferring process, no structure is blocked between the bottom of the battery pack and the upper surface of the battery replacing equipment or the inner bottom surface of the battery bin, the battery frame only needs to leave enough height space for the entering and the exiting of the battery pack, no additional height space is needed for the entering and the exiting of the battery frame of the battery transferring device, and the layer height of each battery bin of the battery frame can be reduced. Second, two extension piece follow battery package both sides centre gripping battery package for battery package is transported and is kept predetermined direction throughout in the mutual in-process, can not take place the skew, thereby improves the mutual efficiency of battery package. Thirdly, the bottom of the battery pack and the upper surface of the battery replacing equipment or the inner bottom surface of the battery bin can be provided with smaller distances, so that the acting force of the battery pack on the battery replacing equipment and the battery rack in the vertical direction can be conveniently controlled, and the impact of the weight of the battery pack on the battery replacing equipment and the battery rack is reduced.

As an alternative implementation manner of a battery transferring device, further, the battery accommodating bin includes at least two side walls extending in a vertical direction and opposite to each other, and the two protruding members are respectively disposed on the two side walls and symmetrically disposed.
