Multiple screw holes are provided on the side of the fixing strip 3, which is then fixed to the inner side of the housing 2 by multiple screws. Multiple screw holes are also provided on the other side of the fixing strip 3, which is used to fix the cover 1 to the fixing strip 3. By providing the fixing strip 3, the cover 1 can be connected to the side of the housing 2 by screws, enhancing the connection between the cover 1 and the housing 2 and allowing the cover 1 to be fixed to the housing 2. All screws described herein... Sealing gaskets or sealant are provided at the connection points of the threaded holes and screws to improve the airtightness of the housing 2 and enhance the waterproof effect. The fixing strip 3 is an aluminum strip, and a first support pad 5 is provided at the bottom of the fixing strip 3. A second support pad 6 is provided on the inner side of the bottom of the housing 2. Both the first support pad 5 and the second support pad 6 are used to limit the position of the battery pack 4. The first support pad 5 is located between the top of the battery pack 4 and the fixing strip 3, and the second support pad 6 is located between the bottom of the battery pack 4 and the housing 2. Both the first support pad 5 and the second support pad 6 are rubber pads made of rubber or silicone, which can support the battery pack 4, keep the battery pack 4 stable, and prevent the battery pack 4 from shaking. The top of the battery pack 4 refers to the end of the battery pack 4 that is close to the cover 1, and the bottom of the battery pack 4 refers to the end of the battery pack 4 that is away from the cover 1. By setting a fixing strip 3, a first support pad 5, and a second support pad 6, the battery pack 4 is installed between the first support pad 5 and the second support pad 6. When the fixing strip 3 is installed, the first support pad 5 can be squeezed, and then the first support pad 5, together with the second support pad 6, can limit the battery pack 4 and prevent the battery pack 4 from shaking.

[0031] In this embodiment, a waterproof gasket 7 is provided between the fixing strip 3 and the housing 2.

The waterproof gasket 7 is provided with multiple perforations, and the waterproof gasket 7 can be fixed to the fixing strip 3 with screws.

[0032] In this embodiment, there are two fixing strips 3, which are arranged opposite to each other on the side of the housing 2. By setting two fixing strips 3, the cover 1 can be connected to both sides of the housing 2 at the same time, thereby improving the fixing effect of the cover 1 on the housing 2.

[0033] In this embodiment, a sealing ring 8 is provided between the cover 1 and the housing 2. The sealing ring 8 is provided along the opening edge of the housing 2 to improve the sealing effect between the cover 1 and the housing 2. A protrusion 81 is provided on the side of the sealing ring 8, and the protrusion 81 has a through hole. The cover 1 is provided with a groove 10 that matches the protrusion 81. One end of the screw passes through the cover 1 and the through hole and is connected to the housing 2 or the fixing strip 3.

[0034] In this embodiment, at least one buffer pad 9 is provided between the battery pack 4 and the housing 2. The buffer pad 9 is a rubber pad used to fill the gap between the side of the battery pack 4 and the inner side of the housing 2 to prevent the battery pack 4 from shaking.

[0035] Example 2

[0036] The difference between this embodiment and Embodiment 1 is that a groove 41 is provided on the side of the battery pack 4, and one side of the buffer pad 9 extends into the groove 41. By providing the groove 41, the buffer pad 9 is less likely to shift, ensuring the filling effect of the buffer pad 9. There are four buffer pads 9 and four grooves 41, two of which are adjacent to each other on one side of the battery pack 4, and the other two are adjacent to each other on the other side of the battery pack 4. By providing multiple buffer pads 9, the filling effect can be improved and the battery pack 4 can be prevented from shaking.

[0037] In this embodiment, the side of the housing 2 is provided with multiple mounting parts 21, and the cover 1 is provided with multiple connectors 11. One end of the connector 11 passes through the cover 1 and connects with the mounting part 21. A recess 22 is formed between adjacent mounting parts 21, and one side of the buffer pad 9 extends into the recess 22. The connector 11 is a screw, and the mounting part 21 is provided with screw holes. By providing the mounting part 21, the connection effect between the connector 11 and the housing 2 can be improved; by providing the recess 22, the buffer pad 9 is less likely to shift, ensuring the filling effect of the buffer pad 9.

[0038] In this embodiment, the cover 1 is provided with a charging port 12 and a discharging port 13, and the battery pack 4 is electrically connected to the charging port 12 and the discharging port 13 respectively. The charging port 12 is used to charge the battery pack 4, and the discharging port 13 is used to discharge the battery pack 4.

[0039] In this embodiment, a power meter 14 is provided on the cover 1. The power meter 14 is electrically connected to the battery pack 4 and is used to display the power level.

[0040] In this embodiment, a vent valve 15 is provided on the cover 1. The vent valve 15 is connected to the inside of the shell 2. The vent valve 15 is used to allow air to pass through the battery pack 4 and maintain the pressure balance inside and outside the shell 2.

[0041] In this embodiment, a handle 16 is provided on the cover 1.

[0042] The other structures in this embodiment are the same as those in Embodiment 1, and will not be described again here.

[0043] Example 3

[0044] An energy storage device includes a battery box as described in Embodiment 1 or Embodiment 2. A battery pack 4 is disposed inside the housing. A first support pad 5 is disposed between the top of the battery pack 4 and a fixing strip 3, and a second support pad 6 is disposed between the bottom of the battery pack 4 and the housing 2. By setting the fixing strip 3, the first support pad 5, and the second support pad 6, the battery pack 4 is installed between the first support pad 5 and the second support pad 6. When the fixing strip 3 is installed, the first support pad 5 can be squeezed, and then the first support pad 5, together with the second support pad 6, can limit the battery pack 4 and prevent the battery pack 4 from shaking.

[0045] Obviously, this utility model includes a cover and a shell, which are fitted together. Both the cover and the shell have multiple screw holes, through which screws connect them. At least one fixing strip is installed on the inner side of the shell, with multiple screw holes on one side. The fixing strip is fixed to the inner side of the shell by multiple screws. The other side of the fixing strip also has multiple screw holes, allowing the cover to be fixed to the fixing strip. By using the fixing strip, the cover can be connected to the side of the shell via screws, enhancing the connection between the cover and the shell and allowing the cover to be fixed to the shell. All screw holes and screw connections described herein... Sealing gaskets or sealants are installed at all locations to maintain the airtightness of the casing and improve waterproofing. The fixing strip is made of aluminum, with a first support pad at its bottom and a second support pad on the inner side of the bottom of the casing. Both the first and second support pads are used to limit the battery pack's position. The first support pad is located between the top of the battery pack and the fixing strip, and the second support pad is located between the bottom of the battery pack and the casing. Both the first and second support pads are rubber or silicone pads, which support the battery pack, maintain its stability, and prevent it from shaking. The top of the battery pack refers to the end of the battery pack closest to the cover, and the bottom of the battery pack refers to the end of the battery pack furthest from the cover. This utility model, by setting a fixing strip, a first support pad, and a second support pad, with the battery pack installed between the first and second support pads, allows the fixing strip to compress the first support pad, which, together with the second support pad, limits the battery pack's position and prevents it from shaking.
