This allows for quick replacement of the vehicle's power battery without prolonged charging, significantly improving the convenience and efficiency of electric vehicles.

[0028] It can be understood that the first connecting piece 1 is installed on the vehicle frame 200, the first connecting piece 1 has a cavity 111 and an open hole, which facilitates the access of the second connecting piece 2, the second connecting piece 2 is located on the power battery mounting bracket 300 and matches the cavity 111 in the first connecting piece 1, the second connecting piece 2 enters the cavity 111 through the open hole, realizes the mechanical connection between the battery and the vehicle body, and can realize battery replacement without electric control, the second connecting piece 2 needs to ensure that it can remain stable without external force, and can smoothly enter or exit the cavity 111 of the first connecting piece 1 under the action of external force, so as to facilitate the installation and disassembly of the battery; the locking piece 3 is arranged in the cavity 111 of the first connecting piece 1, after the second connecting piece 2 enters, the locking piece 3 is matched with the second connecting piece 2 to lock the battery replacement mechanism 100, and it is ensured that the battery will not accidentally fall off during vehicle driving.

[0029] The working principle of the battery replacement mechanism 100 is as follows:

[0030] First, the first connecting piece 1 is fixed with the vehicle frame 200, the second connecting piece 2 is fixed with the power battery mounting bracket 300, then an external force is applied to the second connecting piece 2 to make the second connecting piece 2 exit the cavity 111 of the first connecting piece 1, at this time the battery replacement mechanism 100 switches to the unlocking state;

[0031] When the battery replacement mechanism 100 is in the unlocking state, an external force is applied to the second connecting piece 2 to make the second connecting piece 2 extend into the cavity 111 of the first connecting piece 1, the locking piece 3 cooperates with the second connecting piece 2, at this time the battery replacement mechanism 100 is in the locking state, so that the vehicle battery replacement is completed.
