[0034] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0035] Please refer to Figures 1 to 4 , an energy storage device that is easy to maintain, comprising a protective housing 1, a control component 2 and an energy storage component 3;

[0036] At least two accommodating chambers 4 are provided in the protective shell 1, and the adjacent accommodating chambers 4 are connected to each other. The surface of the protective shell 1 is provided with inlets and outlets 5 corresponding to each other and connected to the accommodating chambers 4.

[0037] The control component 2 and the energy storage component 3 are arranged in the corresponding accommodating chamber 4, and the control component 2 and the energy storage component 3 can slide in a direction close to or away from the inlet and outlet 5, and the control component 2 is electrically connected to the energy storage component 3;

[0038] A baffle 8 is provided on one side of the control component 2 away from the accommodating chamber 4 and on one side of the energy storage component 3 away from the accommodating chamber 4 . The size and shape of the baffle 8 match the size and shape of the inlet and outlet 5 .

[0039] From the above description, it can be seen that the beneficial effects of the utility model are: designing a protective shell 1 with a accommodating chamber 4, and designing the control component 2 and the energy storage component 3 to be a drawer-type structure that can slide in and out of the accommodating chamber 4, so that the control component 2 and the energy storage component 3 are easy to disassemble and assemble, and easy to replace. At the same time, the installed baffle 8 can perfectly cover the inlet and outlet 5, thereby improving the sealing performance of the equipment, which is not only convenient for replacement and maintenance operations, but also allows the battery to be replaced at any time when there is no power, thereby improving the durability of the product.

[0040] Furthermore, a guide rail bracket 6 is provided in the accommodating chamber 4;

[0041] The control assembly 2 and the energy storage assembly 3 are respectively slidably disposed on the corresponding guide rail bracket 6 .

[0042] It can be seen from the above description that by providing the guide rail bracket 6, the sliding process of the control component 2 and the energy storage component 3 entering and exiting the accommodating chamber 4 can be smoother and more labor-saving, making the component replacement operation more convenient.

[0043] Furthermore, the guide rail bracket 6 is provided to separate adjacent accommodating chambers 4 .

[0044] It can be seen from the above description that adjacent accommodating chambers 4 are separated by means of the guide rail bracket 6, which can reduce the complexity of the internal structure, increase the integration, and facilitate internal wiring.

[0045] Further, the length of the accommodating chamber 4 in the straight direction close to or away from the inlet and outlet 5 is greater than the length of the control component 2 and the energy storage component 3 in the straight direction close to or away from the inlet and outlet 5;

[0046] A first power socket 27 is disposed on a surface of the control component 2 away from the baffle 8 , and a second power socket 33 is disposed on a surface of the energy storage component 3 away from the baffle 8 . The first power socket 27 is electrically connected to the second power socket 33 .

[0047] From the above description, it can be seen that hiding the wiring connection between the control component 2 and the energy storage component 3 at the back of the accommodating chamber 4 can improve the simplicity and aesthetics of the device.

[0048] Further, the control assembly 2 includes a control module 21, a buck-boost power supply module 22, an inverter module 23, a DC input socket 24, an AC input socket 25 and an AC output socket 26;

[0049] The DC input socket 24, the AC input socket 25 and the AC output socket 26 are all arranged on the baffle 8 of the control assembly 2;

[0050] The control module 21 is respectively communicated with the inverter module 23, the first power socket 27 and the buck-boost power supply module 22; the inverter module 23 is respectively electrically connected with the buck-boost power supply module 22, the first power socket 27, the AC input socket 25 and the AC output socket 26; and the DC input socket 24 is electrically connected with the buck-boost power supply module 22.

[0051] From the above description, it can be seen that the control component 2 partially integrates functions such as AC output, AC output and DC input, and the corresponding sockets are arranged on the surface of the baffle 8 to facilitate the user to connect the wires.

[0052] Furthermore, the energy storage component 3 includes a battery pack 31 and a battery management system 32;

[0053] The battery pack 31 is electrically connected to the second power socket 33 through the battery management system 32 .

[0054] From the above description, it can be seen that the energy storage component 3 integrates the battery and the battery management system 32, making the power supply more flexible and intelligent, and facilitating module replacement.

[0055] Furthermore, a limiting member is also provided in the accommodating chamber 4;

[0056] When the control component 2 and the energy storage component 3 are located in the accommodating chamber 4 , the control component 2 and the energy storage component 3 are respectively detachably connected to one of the limiting members.

[0057] Furthermore, when the control component 2 and the energy storage component 3 are located in the accommodating chamber 4 , the control component 2 and the energy storage component 3 are respectively snap-connected with one of the limiting members.

[0058] From the above description, it can be seen that by setting a limiter, the control component 2 or energy storage component 3 that slides into the accommodating chamber 4 and the baffle 8 covers the inlet and outlet 5 can be limited and fixed to prevent it from automatically sliding out during use.

[0059] Furthermore, a wiring frame 10 is provided in the accommodating chamber 4, and the wiring frame 10 has a connecting wire 7 built therein;

[0060] The control component 2 and the energy storage component 3 are electrically connected via the connecting line 7 .
