The locking accessory 20 may be a member capable of connecting the load bearing structure 10 to the connection structure 311. Specifically, the locking accessory 20 may be a connection bolt screwed to the connection structure 311 of the mounting part 3 through a part of the structure of the bearing structure 10, so that an end portion of the mounting part 3 protruding outside the case 1 can be conveniently detachably connected to the bearing structure 10.

In some embodiments, the powered device is a vehicle such that the battery in the vehicle can maintain a good seal, making the vehicle less likely to be affected by external rain or the like.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model, and are intended to be included within the scope of the appended claims and description. In particular, the technical features mentioned in the respective embodiments may be combined in any manner as long as there is no structural conflict. The present utility model is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions falling within the scope of the claims.
