The mounting structure 5 is specifically located at a preset mounting position on the electric equipment, where the preset mounting position is used for mounting a quick-change battery pack.

Referring to fig. 6 to 10, in some embodiments, the mounting structure 5 may specifically include a first limiting member 51 and a second limiting member 52, where the first limiting member 51 is located at a front side of the quick-change battery pack insertion direction, and the second limiting member 52 is located at a rear side of the quick-change battery pack insertion direction. The first retaining member 51 is configured to be engaged with the end cap 2 located at the front end in the insertion direction of the quick-change battery pack, and the second retaining member 52 is configured to be engaged with the end cap 2 located at the rear end in the insertion direction of the quick-change battery pack, so as to retain the quick-change battery pack.

Specifically, the first limiting member 51 and the second limiting member 52 are disposed on the electric equipment, for example, the electric equipment is a vehicle, the vehicle has a vehicle body frame 6, and the first limiting member 51 and the second limiting member 52 can be disposed on the vehicle body frame 6 respectively. Through setting up first locating part 51 and second locating part 52 to carry on spacingly from battery package body 1 both ends respectively, thereby lock the quick change battery package in above-mentioned predetermined mounted position, improved the stability of quick change battery package.

Further, the mounting structure 5 may further include a supporting member 53, the supporting member 53 is used for supporting the battery pack body 1, and the first limiting member 51 and the second limiting member 52 are respectively disposed at two ends of the supporting member 53. For example, after the quick-change battery pack is installed on the electric equipment, when the quick-change battery pack is in a lying state, the supporting piece 53 supports the battery pack body 1 from the lower side of the quick-change battery pack, so that the stability of the quick-change battery pack is further improved, and the power supply safety and reliability are further improved.

The end of the supporting member 53 facing the second limiting member 52 has an opening 531 for allowing the quick-change battery pack to enter or move out, and the second limiting member 52 is movable to expose the opening 531 or block the opening 531 to limit the quick-change battery pack.
