Description

Technical Field

[0001] The utility model relates to the field of battery-swapping trolleys, in particular to a battery-swapping trolley that is easy to position. Background Art

[0002] For battery replacement of new energy electric vehicles, the chassis type is currently the mainstream method on the market. After lifting the battery replacement vehicle to a certain height, the battery replacement cart first removes the dead battery from the bottom of the battery replacement vehicle, transfers the fully charged battery out of the battery compartment, and transports it to the bottom of the battery replacement vehicle. Then, through a series of mechanical actions, the fully charged battery is installed to the bottom of the battery replacement vehicle, thereby completing the battery replacement operation.

[0003] For the chassis battery swap mode of new energy electric vehicles, it is necessary to ensure that the positions of the battery swap vehicle and the battery swap cart are accurately positioned. If there is a position offset between the battery swap vehicle and the battery swap cart, the battery swap failure will occur, and in severe cases, the battery swap vehicle, battery pack and battery swap equipment will be damaged. At present, most battery swap carts use a drive motor to drive the roller to achieve the reciprocating movement of the battery swap cart. In actual operation, this method of moving the drive wheel will cause slippage. Secondly, when cooperating with the battery swap vehicle to load and remove the battery, it will move, resulting in inaccurate positioning. The above two situations often lead to the failure of battery swap, reduce the success rate of battery swap, and in severe cases, damage the battery swap vehicle, battery pack and battery swap equipment.

The driving sprocket 4, the first driven sprocket 5, and the second driven sprocket 6 are respectively mounted on the mounting base 3. The first driven sprocket 5 and the second driven sprocket 6 are arranged on the same side of the driving sprocket 4. The driving sprocket 4 is connected to the output end of the motor 8. The chain 7 passes through the first driven sprocket 5, the driving sprocket 4, and the second driven sprocket 6 in sequence. The two ends of the chain 7 are respectively fixed to preset fixed points at the two ends of the reciprocating operation of the frame 1. The driving sprocket 4, the first driven sprocket 5, and the second driven sprocket 6 are triangular in structure, with the driving sprocket 4 at the top corner.

[0031] The driving mechanism 2 further comprises a mounting member 9, which is embedded in the frame 1.
