[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0018] In the embodiments of this application, please refer to Figs. 1-3 As shown, this application provides a split-type connecting frame structure, which includes a front section, a middle section, and a rear section that are separately arranged. One end of the front section is provided with a first connecting part arranged at four corners. The two ends of the middle section are respectively provided with a second connecting part and a third connecting part arranged at four corners. One end of the rear section is provided with a third connecting part arranged at four corners. The first connecting parts and the second connecting parts, and the third connecting parts and the third connecting parts are connected by fasteners to make the frame structure a whole. The middle section is a groove that is closed on at least three sides. The interior of the frame structure after the front section, middle section, and rear section are connected forms a housing compartment for accommodating batteries. The middle section can be replaced with different lengths to adjust the size of the housing compartment.

[0019] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.
