[0027] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0028] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0030] An embodiment of this utility model provides a battery mounting structure, such as... Figure 1-3 As shown, the device includes an inner casing 100 and a battery pack 200. The battery pack 200 is placed inside the inner casing 100. The inner casing 100 can generally be box-shaped and can be integrally formed or assembled from multiple side panels. The battery pack 200 includes multiple stacked batteries 210, which are distributed in layers, with one or more batteries 210 in each layer. An opening is formed on the front side of the inner casing 100, through which the batteries 210 can be inserted into or removed from the inner casing 100.

[0031] A limiting bracket 300 is fixed to the front side of the inner casing 100 to restrict the battery 210 from moving out of the inner casing 100. The limiting bracket 300 is located in front of the battery 210 and serves to prevent the battery 210 from moving forward, thus confining the battery 210 within the inner casing 100. A first insulating plate 410 is provided on the front side of the limiting bracket 300, making it less likely for the battery 210 to short-circuit with other devices in front of it. A second insulating plate 420 is provided between the battery pack 200 and the inner casing 100, making it less likely for the battery pack 200 to short-circuit with the inner casing 100. In this embodiment, the insulating plates are used to enhance the insulation performance of the battery 210, thereby providing insulation protection for the battery 210 and improving the safety of the energy storage battery.

[0032] Meanwhile, due to the presence of the limiting frame 300, a channel is formed between the first insulating plate 410 and the battery 210. This channel allows for wiring between batteries 210 and connection between batteries 210 and other components such as circuit boards, facilitating wiring.

[0033] In some embodiments, the battery 210 is typically cuboid in shape, and the battery pack 200 formed by stacking the batteries 210 is also generally cuboid in shape. A second insulating plate 420 is provided between the top surface of the battery pack 200 and the inner casing 100, between the bottom surface of the battery pack 200 and the inner casing 100, between the rear side surface of the battery pack 200 and the inner casing 100, between the left side surface of the battery pack 200 and the inner casing 100, and between the right side surface of the battery pack 200 and the inner casing 100. Thus, except for the front side, the battery pack 200 has a second insulating plate 420 between it and the inner casing 100 on all five other sides, which greatly reduces the possibility of electrical contact between the battery pack 200 and the inner casing 100, further enhancing the insulation performance of the battery 210 and further improving the safety of the energy storage battery.

[0034] In some embodiments, a third insulating plate 430 is provided between adjacent batteries 210. The third insulating plate 430 can improve the insulation between adjacent batteries 210, thereby further improving the safety of the energy storage battery. When each layer of the battery pack 200 has only a single battery 210, a third insulating plate 430 is provided between adjacent batteries 210 on the upper and lower sides. When each layer of the battery pack 200 has only a single battery 210, a third insulating plate 430 is provided between adjacent batteries 210 on the upper and lower sides, and a third insulating plate 430 is also provided between adjacent batteries 210 on the same layer, further enhancing the insulation performance.

[0035] In some embodiments, a pressure relief valve is provided on the front side of the battery 210. When the battery 210 experiences a short circuit or other problems that cause internal pressure to rise, the pressure relief valve can open in time when the pressure rises to a certain level to release the pressure and prevent accidents such as battery casing rupture or explosion due to excessive pressure. The limiting frame 300 is provided with an opening 310 opposite to the pressure relief valve. Thus, the limiting frame 300 can limit the battery 210 without affecting the pressure relief of the battery 210 under abnormal conditions, further ensuring the safety of the battery 210.

[0036] In some embodiments, the limiting frame 300 is provided with a wiring groove 320, through which the wiring between adjacent batteries 210 can pass. The wiring groove 320 provides space for wiring and can also position the connecting wires and restrict their movement.

[0037] In some embodiments, a partition plate 440 is fixed to the top of the inner housing 100, and a circuit board is fixed above the partition plate 440. The partition plate 440 isolates the battery 310 and the circuit board, preventing short circuits between the battery 310 and the circuit board and further improving safety.

[0038] In this embodiment, the isolation plate 440 can be made of insulating material, and can be made of rigid insulating material, such as plastic, so that it can not only play the role of isolation, but also effectively support the circuit board.

[0039] An embodiment of this utility model provides an energy storage device, such as... Figure 4 As shown, the battery mounting structure includes the outer casing 500 and any of the above embodiments. Specific details regarding the battery mounting structure can be found in the above embodiments and will not be repeated here. The inner casing is fixed within the outer casing 500, and the battery is encased in a double-layer casing, enhancing insulation protection for the battery 210 and improving the safety of the energy storage battery.

[0040] In some embodiments, such as Figure 5 As shown, a groove 510 is provided on the top of the rear side of the housing 500, and a connector 520 is fixed on the inner wall of the groove 510. The energy storage battery needs to connect to external devices through the connector 520 to receive externally supplied electrical energy or output stored electrical energy. In this embodiment, the connector 520 is placed in the groove 510, which provides more room for bending and routing of the connecting wire, facilitating wiring. At the same time, the groove 510 is located on the top of the housing 500, allowing the connecting wire to bend directly upwards and run, reducing the wiring path.

[0041] In some embodiments, a bracket 530 is fixed to the rear side of the housing 500, and the entire energy storage device can be installed in a designated location such as a wall through the bracket 530.

[0042] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
