[0033] A combined structure of a main body energy storage battery and an expansion component, see Figure 1-2 As shown, it includes an energy storage main body 200 and an expansion module 100 detachably connected to the energy storage main body 200; the energy storage main body 200 is usually an energy storage unit, with the ability to store electrical energy and discharge; at least one installation groove 210 is provided on the energy storage main body 200; the expansion module 100 is detachably connected to the installation groove 210; through the installation groove 210, the energy storage main body 200 can be adapted to at least one expansion module 100, so as to increase the usage scenarios; the expansion module 100 is at least one of a power bank, a radio, a fan, a speaker, a USB module, a lamp, etc.;

[0034] In an embodiment, at least one self-locking buckle 220 is provided in the installation groove 210; a hook 131 cooperating with the self-locking buckle 220 is provided on the expansion module 100; the buckle and the self-locking buckle 220 are locked and unlocked by pressing; specifically, during installation, the expansion module 100 is set in the installation groove 210 and pressed towards the inside of the installation groove 210 to achieve locking; when unlocking is required, further press the expansion module 100 to achieve unlocking; the unlocking state and locking state of the self-locking buckle 220 and the hook 131 can be seen in Figure 6-7 ; the structure of the self-locking buckle 220 is a common structure in the art, and the specific principle of its pressing locking and unlocking will not be elaborated here; the relevant principle can be seen in the European patent with the patent publication number EP 0676522 A2.

[0035] In one embodiment, in order to make the expansion module 100 automatically pop out of the installation slot 210 after unlocking, a jacking component 140 is provided on the expansion module 100; the jacking component 140 is preferably a spring component, which can not only reduce costs but also ensure the effect of automatic popping out; when the expansion module 100 is locked with the self-locking buckle 220 in the installation slot 210, the spring in the jacking component 140 is compressed, and when the self-locking buckle 220 is unlocked, the spring releases elastic force to jack up the expansion module 100 so that it protrudes from the installation slot 210, facilitating the user to take it; further, in order to ensure that the spring can be compressed every time the expansion module 100 is pressed down and locked, usually a part of the spring extends out of the bottom of the expansion module 100, but this will affect the appearance of the expansion module 100 and is not conducive to the long-term use of the jacking component 140. Therefore, the jacking component 140 is arranged on the side of the main body 110 of the expansion module 100, and the bottom of the jacking component 140 does not exceed the bottom of the expansion module 100.

[0037] In some embodiments; the installation is in a rounded rectangle shape, and four self-locking buckles 220 are provided at its four corners, and support members 230 are provided between the adjacent buckles; by connecting with the expansion module 100 through the four self-locking buckles 220, the stability of locking the expansion module 100 can be effectively improved, and at the same time, the force on the expansion module 100 during pressing for locking / unlocking can be ensured to be uniform.

[0038] In one embodiment, the expansion module 100 includes a main body portion 110 and a top shell 120 located at the top of the main body portion 110; an outer edge of the top shell 120 is provided with an extension portion 130 that extends away from the main body portion 110 and protrudes from the main body portion 110; the hook 131 is disposed below the extension portion 130. When the expansion module 100 is engaged with the installation groove 210, the extension portion 130 is located below the self-locking buckle 220. By providing the extension portion 130, the connection portion between the hook 131 and the self-locking buckle 220 can be shielded, enhancing the aesthetics when the expansion structure is connected to the energy storage main body 200.

[0039] In one embodiment, referring to Figure 3-4 As shown, the expansion module 100 is a power bank; a boss 111 is formed by extending the lower end of the main body portion 110; a step groove 112 and a receiving groove 113 are formed between the boss 111 and the main body portion 110; a handle 114 is provided in the step groove 112; a spring pin 150 is provided in the receiving groove 113; the handle 114 is specifically a cord-like handle 114, which is convenient for folding and taking, and can be hidden in the step groove 112 to ensure the normal installation of the expansion module 100 and the installation groove 210.
