[0020] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0021] Example 1

[0022] A high-voltage energy storage box, such as Figure 1-Figure 3As shown, the box body 1 includes a shell body 2 with an opening at the upper end and a cover plate 3 arranged at the opening of the shell body 2. An annular sealing gasket 4 is provided at the connection between the cover plate 3 and the shell body 2, wherein the annular sealing gasket 4 is a silicone strip sealing gasket made of closed-cell liquid silicone foam, which fills the gap between the cover plate 3 and the shell body 2 to prevent water vapor from entering and damaging the internal components of the box body 1, thereby increasing the waterproof performance of the entire box body 1.

[0023] A fire sprinkler 5 and a detector 6 for detecting the gas composition in the box are installed on the side wall of the shell 2. The detector 6 is connected to the fire sprinkler 5 through a wiring harness and a fire communication interface. The detector 6 is used to monitor the gas composition inside the box 1 and detect the concentration of aerosols or smoke particles generated in the early stage of material combustion. It can prevent the high-voltage components inside the box 1 from increasing contact resistance due to poor contact or high-temperature splashes caused by the opening of the fuse, which may cause thermal fire risks. When the detector 6 detects an abnormality, it will send a signal to the controller, and the controller will control the fire sprinkler 5 to spray the fire extinguishing agent in time. In this embodiment, the fire sprinkler 5 is a perfluorohexanone sprinkler, which relies on heat absorption to achieve the effect of fire extinguishing. In the actual product, the fire pipe and the corresponding fire extinguishing agent storage unit will be connected to the fire sprinkler 5. The fire pipe and the fire extinguishing agent storage unit can be arranged inside or outside the box 1.

[0024] In addition, in this embodiment, a waterproof breathable valve 7 is installed on the side wall of the shell 2 to maintain the balance of air pressure inside and outside the box 1, which can effectively ensure that the air pressure inside and outside the box 1 remains balanced. It can be used to circulate air inside and outside the box 1 without reducing the original protection level of the box 1, thereby further enhancing the safety and stability of the high-pressure box.

[0025] The energy storage high-pressure box provided in this embodiment integrates a waterproof module, a fireproof module and an air pressure balance module, which can achieve better waterproof and fireproof performance, has better protection performance and safety performance, and can meet more stringent application scenarios.

[0026] In this embodiment, an annular flange 201 is provided at the edge of the open end of the shell 2, and the annular flange 201 is connected to the edge of the cover plate 3 by a plurality of evenly arranged screws. The shape of the annular sealing gasket 4 matches the annular flange 201 and is arranged between the annular flange 201 and the edge of the cover plate 3. The annular sealing gasket 4 is provided with a screw hole 202 for the screw to pass through. The setting of the annular flange 201 can better install the annular sealing gasket 4 and ensure the sealing performance of the annular sealing gasket 4.

[0027] In this embodiment, to better position the rear end of the high-voltage control box on the battery mounting frame during installation, positioning guide pins 8 extending outward from the rear side of the housing 2 are riveted onto the rear side. These guide pins 8 are used to position the housing 1 on the battery mounting frame. To maintain lateral force balance and accurate positioning, two guide pins 8 are provided, one at each end of the rear side of the housing 2. These guide pins are riveted onto the housing 1, ensuring a good seal and effectively preventing damage at the assembly point.

[0028] In addition, in order to facilitate the removal of the box body 1 from the battery mounting rack, a handle 9 for removing the box body 1 from the battery mounting rack is provided on the front side of the shell 2. There are two handles 9 and they are arranged opposite to the positioning guide pins 8, thereby facilitating the removal process or avoiding interference with the positioning guide pins 8.

[0029] At the same time, in order to further ensure the overall sealing of the box body 1, the handle 9 is obtained by stamping and forming, and there will be no installation gaps or other potential water leakage. The handle 9 includes a stamping groove 901 stamped inward from the front side of the shell 2. One side wall of the stamping groove 901 is configured as an inclined guide surface 902, and the other side wall is configured as an arc-shaped handle portion 903 protruding toward the middle of the stamping groove 901. The length direction of the stamping groove 901 is arranged along the height direction of the box body 1. The inclined guide surface 902 is arranged on the side of the stamping groove 901 close to the edge of the box body 1 and forms an obtuse angle with the bottom surface of the stamping groove 901. The arc-shaped handle portion 903 is arranged on the side opposite to the inclined guide surface 902 and its length direction is arranged along the height direction of the box body 1. During operation, the construction worker extends his hand into the stamping groove 901 along the inclined guide portion, and then applies force to the arc-shaped handle portion 903 to remove the box body 1 axially along the positioning guide pin 8.

[0030] The cooperation between the positioning guide pin 8 and the handle 9 can facilitate the removal and maintenance of the box body 1, and can also facilitate the positioning and installation of the box body 1, providing better disassembly and assembly convenience.

[0031] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application based on one or several embodiments provided in the present application to obtain other embodiments, and these embodiments do not exceed the scope of protection of the present application.

[0032] In short, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention patent.
