In other examples, the mating structure 302 may also define a slot 2041, and the slot 2041 is open at an upper portion, and the positioning structure 204 forms a boss protruding from an inner side surface of the battery mounting frame 20, where the boss is matched with the slot 2041, and the quick-change battery pack 30 moves upward to enable the mating structure 302 to be inserted by the positioning structure 204, so as to implement a positioning function of the positioning structure 204 on the quick-change battery pack 30.
As shown in fig. 4, in some examples, the abutment position of the engaging structure 302 and the positioning structure 204 is higher than the engaging positions of the locking pin 301 and the power change lock 202, so that after the engaging structure 302 is inserted into the slot 2041 of the positioning structure 204 and before the engaging structure 302 is inserted into the bottom of the slot 2041, the locking pin 301 can engage with the power change lock 202, thereby improving the success rate of installing the quick-change battery pack 30 and simplifying the operation steps.
In addition, the matching structure 302 can be inserted into the slot 2041 of the positioning structure 204 before the lock pin 301 is matched with the power conversion lock 202, so that the positioning effect is good.
As shown in fig. 2 and 3, in some examples, the mounting location has an electrical connector 42, the electrical connector 42 is located at the top of the mounting cavity 201, the top of the quick-change battery pack 30 has a docking structure 303, and during installation of the quick-change battery pack 30, the docking structure 303 interfaces with the electrical connector 42 to enable current conduction, i.e., the quick-change battery pack 30 may deliver electrical energy to the vehicle 100 through the electrical connector 42 and the docking structure 303.
