[0037] In order to make the technical problems solved by the present application, the technical solutions adopted and the technical effects reached more clear, the technical solutions of the present application will be further described below in combination with the drawings and through specific embodiments.

[0038] In the description of the present application, unless explicitly defined and limited otherwise, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrated; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0039] In the present application, unless explicitly defined and limited otherwise, the "upper" or "lower" of the first feature to the second feature can include the direct contact of the first and second features, or the contact of the first and second features through another feature between them. Moreover, the "upper", "upper" and "upper" of the first feature to the second feature include the vertical direction of the first feature above and oblique above the second feature, or only indicate that the horizontal height of the first feature is higher than that of the second feature. The "lower", "lower" and "lower" of the first feature to the second feature include the vertical direction of the first feature below and oblique below the second feature, or only indicate that the horizontal height of the first feature is less than that of the second feature.

[0040] In the description of the present embodiment, the terms "upper", "lower", "left", "right" and other orientation or position relationship are based on the orientation or position relationship shown in the drawings, only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second" are only used to distinguish in description, and have no special meaning.

[0041] As Figures 1-4As shown, the battery test box provided in the embodiment mainly comprises a box body 100, a bottom plate 200, a door plate 300 and a sealing assembly 400. The box body 100 is provided with an opening 110 for the battery pack to enter or exit, and the bottom plate 200 is fixedly connected with the box body 100. The door plate 300 can open or close the opening 110. The sealing assembly 400 is arranged at the end of the door plate 300 close to the bottom plate 200, so that the sealing assembly 400 seals the box body 100, and the sealing assembly 400 can elastically deform with the opening and closing of the door plate 300.

[0042] Based on the above design, in the embodiment, the battery test box can be a walk-in battery test box, that is, the upper end surface of the bottom plate 200 is flush with the ground, which is convenient for the battery pack to enter or exit the inside of the box body 100. A fire-fighting water inlet (not shown in the figure) is formed in the box body 100, and the fire-fighting water inlet is communicated with a fire hydrant (not shown in the figure). One side of the box body 100 is provided with the opening 110, and the door plate 300 can be one or two, thereby realizing the closing and opening of the opening 110. Exemplarily, one door plate 300 is arranged in the embodiment, thereby reducing the generation of gaps and improving the sealing performance of the battery test box. The sealing assembly 400 is made of rubber material with a certain elasticity. When the door plate 300 is in a closed state, that is, the door plate 300 closes and blocks the opening 110, at this time, the sealing assembly 400 is in a compressed state, that is, at this time, the gap between the sealing assembly 400 and the bottom plate 200 and the door plate 300 is in an interference fit, thereby realizing the sealing of the battery test box by the sealing assembly 400. When the battery pack in the battery test box has a dangerous phenomenon such as fire or explosion, the user can open the fire hydrant, so that water can enter the inside of the battery test box through the fire-fighting water inlet, thereby realizing the timely fire extinguishing of the battery pack, avoiding greater danger caused by the thermal runaway of the battery pack, and improving the safety performance of the battery test box.

[0043] Compared with the prior art, the battery test box provided in the embodiment realizes the sealing of the box body 100 by arranging the sealing assembly 400 at the end of the door plate 300 close to the bottom plate 200. When the fire hydrant injects water into the inside of the box body 100, the sealing assembly 400 can prevent water from flowing out from the gap between the box body 100 and the bottom plate 200, thereby enabling the water in the inside of the box body 100 to gather and effectively cool and extinguish the fire of the battery pack, and improving the sealing performance of the battery test box. In the inside of the box body 100, there is no need to additionally arrange the baffle in the conventional technology, that is, when the battery pack enters the battery test box, there is no need for the user to disassemble the baffle, thereby improving the efficiency of the battery pack entering the battery test box, achieving the purpose of saving labor cost and improving work efficiency.

[0044] As Figures 3-4As shown, in this embodiment, the base plate 200 includes a first plate 210 and a second plate 220. The first plate 210 and the second plate 220 are integrally formed. The first plate 210 is horizontally arranged, and the second plate 220 is inclined at a preset angle R to the first plate 210. The sealing component 400 abuts against the upper end surface of the second plate 220. Optionally, in this embodiment, the preset tilt angle R is set to 160° to 179°. This results in a larger compression deformation of the sealing component 400 when the door panel 300 is closed and a smaller compression deformation when the door panel 300 is open. In other words, as the user closes the door panel 300, the gap between the door panel 300 and the second plate 220 becomes smaller and smaller. This causes the sealing component 400 to be pressed tighter and tighter by the door panel 300, resulting in a larger deformation of the sealing component 400. This allows the sealing component 400 to form a stable sealing structure with the door panel 300 and the bottom plate 200, thereby improving the sealing performance of the battery test chamber.

[0045] Optionally, in this embodiment, at least two sealing components 400 are provided, and a drainage hole 230 is provided on the second plate 220 between two adjacent sealing components 400. Exemplarily, this embodiment uses two sealing components 400 as an example. When water inside the housing 100 seeps out through the inner sealing component 400, the seeping water can be discharged through the drainage hole 230, thereby preventing the seeping water from creating water pressure on the outer sealing component 400, improving the service life of the sealing component 400, and simultaneously improving the cleanliness of the battery test chamber's appearance.

[0046] Furthermore, in this embodiment, the battery test chamber includes a drain pipe 240, and a receiving cavity 250 is provided inside the bottom plate 200. The drain pipe 240 is partially disposed within the receiving cavity 250, with one end connected to the drain hole 230 and the other end passing through the bottom plate 200. This allows water seeping from the inner sealing assembly 400 to be discharged to the outside of the battery test chamber through the drain pipe 240, thereby preventing water accumulation inside the bottom plate 200 and extending the service life of the bottom plate 200. Exemplarily, in this embodiment, both the drain hole 230 and the drain pipe 240 can be multiple, and the drain holes 230 and drain pipes 240 are correspondingly arranged. For example, the number of drain holes 230 and drain pipes 240 can be 2, 3, 4, etc., which will not be elaborated further here.

[0047] like Figures 3-4 As shown, in this embodiment, a water tank 260 is provided on the base plate 200, and the height of the water tank 260 is not higher than the height of the second plate 220. The water tank 260 is provided so that when water leaks from the outer sealing component 400, the leaked water can flow along the inclined second plate 220 into the water tank 260, thereby preventing the leaked water from leaking out randomly and causing pollution to the external environment.

[0048] like Figure 2 , Figure 5 As shown, in this embodiment, the door panel 300 is closably connected to the housing 100 via a rotating assembly 500, allowing the door panel 300 to open or close the opening 110. Specifically, the rotating assembly 500 includes a first hinge 510 and a second hinge 520. The first hinge 510 is fixedly connected to the housing 100, and the second hinge 520 is fixedly connected to the door panel 300. The first hinge 510 is connected to the second hinge 520 via a screw (not shown in the figure), and a certain gap is provided between the first hinge 510 and the second hinge 520. When the door panel 300 is opened, the second hinge 520 can move in a direction close to the first hinge 510. In other words, during the opening of the door panel 300, the screw rotates synchronously, causing the second hinge 520 to move closer to the first hinge 510. This allows the door panel 300 to rise simultaneously during opening, thereby reducing the friction between the sealing assembly 400 and the second plate 220, reducing the deformation of the sealing assembly 400, and enabling the door panel 300 to open smoothly. It should be noted that the screw in this embodiment can also be replaced with a lead screw, as long as it allows the second hinge 520 to move closer to the first hinge 510 (reducing the gap distance) while rotating. This embodiment does not limit this.

[0049] Furthermore, in this embodiment, the first hinge 510 includes a first fixing part 5101 and a first rotating part 5102, and the second hinge 520 includes a second fixing part 5201 and a second rotating part 5202. The first fixing part 5101 and the first rotating part 5102 are integrally formed, and the second fixing part 5201 and the second rotating part 5202 are integrally formed. The first fixing part 5101 is fixedly connected to the housing 100, and the second fixing part 5201 is fixedly connected to the door panel 300. A screw passes through the first rotating part 5102 and the second rotating part 5202.

[0050] Optionally, in this embodiment, the first fixing part 5101 is provided with a first mounting hole, and the second fixing part 5201 is provided with a second mounting hole. The first fixing part 5101 is connected to the housing 100 and the second fixing part 5201 is connected to the door panel 300 by screws.

[0051] like Figures 1-2As shown, to achieve a stable connection between the door panel 300 and the housing 100, multiple rotating components 500 are provided in this embodiment, and these components are evenly spaced to improve the smoothness of the door panel 300's rotation. When the user needs to place the battery pack inside the housing 100, the user can easily open the door panel 300, improving work efficiency. It should be emphasized that the area of ​​the door panel 300 in this embodiment is larger than the area of ​​the opening 110, so that the door panel 300 can cover the opening 110 when closed, thereby improving the sealing performance of the battery test chamber.

[0052] like Figure 3 As shown, in this embodiment, the housing 100 is provided with a protrusion 120, and a camera 130 is provided inside the protrusion 120. The camera 130 is used to monitor the test status of the battery pack. Optionally, there are two protrusions 120, and each of the two protrusions 120 is provided with a camera 130. This facilitates monitoring the changes of different positions of the battery pack under test conditions, which is beneficial for subsequent analysis.

[0053] Optionally, the box body 100, bottom plate 200 and door panel 300 in this embodiment can all be made of metal materials, such as stainless steel, aluminum alloy and other materials. Of course, operators can also select other materials for manufacturing according to actual needs, which will not be elaborated here.
