[0003] Battery safety testing is a crucial step in the battery manufacturing process to ensure battery safety performance. Battery safety testing is typically conducted in a test chamber, which mainly consists of a housing and some functional components. The housing has two independent chambers: one chamber holds the battery under test, and the other houses the functional components. To ensure the stability of the functional components, they are usually secured to their respective chambers using connectors. During battery safety testing, the battery under test is placed in its corresponding chamber, and then connected to the functional components.

[0004] During battery safety testing, different types of functional components need to be adjusted and replaced depending on the test items. However, the internal space of the enclosure is small and not easy to operate, making the disassembly and assembly of functional components very inconvenient. Utility Model Content

[0048] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The detailed description of the following embodiments and the accompanying drawings are used to illustrate the principles of this application by way of example, but should not be used to limit the scope of this application, that is, this application is not limited to the described embodiments.

[0049] In the description of this application, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicating orientation or positional relationships, are only for the convenience of describing this application 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, and therefore should not be construed as a limitation on this application. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. "Vertical" is not vertical in the strict sense, but within the allowable tolerance range. "Parallel" is not parallel in the strict sense, but within the allowable tolerance range.

[0050] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application depending on the specific circumstances.

[0051] To better understand this application, the following will be combined with... Figures 1 to 10 The embodiments of this application are described below.

[0052] It should be noted that the terms "first direction X," "second direction Y," and "third direction Z" used in this application to indicate direction are only for the purpose of clearly illustrating the specific structure of this application in conjunction with the accompanying drawings, and this application is not limited thereto. The first direction X, second direction Y, and third direction Z are all at angles to each other. Optionally, the first direction X, second direction Y, and third direction Z are all perpendicular to each other. Optionally, the first direction X is horizontal, the second direction Y is vertical, the third direction Z is horizontal, and the first direction X is perpendicular to the third direction Z.

[0053] This application provides a battery safety test chamber for conducting safety tests on batteries. These tests primarily include various performance tests targeting different battery indicators, such as thermal abuse testing, overcharge testing, over-discharge testing, short-circuit testing, impact and vibration testing, drop testing, compression testing, and sealing performance testing. During battery safety testing, situations may arise where the battery catches fire or even explodes. By placing the battery under test in the battery safety test chamber, damage to personnel or objects in the environment due to battery fire or explosion can be effectively prevented.

[0054] like Figures 1 to 3 As shown, the battery safety test box provided in this embodiment includes a box body 1, a first door panel 2, and a tray 3.

[0055] The enclosure 1 defines a sealed space to house the battery under test and some functional components for battery safety testing.

[0056] The housing 1 has a first opening 11 on a first side along the first direction X for allowing functional components to enter and exit the housing 1.

[0057] The first door panel 2 is detachably connected to the first opening 11; it is used to seal the first opening 11 so as to cooperate with the housing 1 to form a sealed space for accommodating the battery under test and functional components, and to conduct battery safety tests.

[0058] The tray 3 is connected to the side of the first door panel 2 facing the inside of the box 1. The tray 3 has a bearing surface; the bearing surface is used to support and fix functional components. According to the changes in the test items in the battery safety test, the staff can disassemble and replace the functional components.

[0059] The first door panel 2 has an open state and a closed state. In the closed state, the first door panel 2 is connected to the box body 1 and closes the first opening 11, forming a sealed space. The tray 3 and the functional components installed on it are located inside the box body 1. In the open state, the first door panel 2 separates from the box body 1 along the first direction X, and the first door panel 2 drives part of the tray 3 to move to the outside of the box body 1, thereby pulling the functional components installed on the tray 3 to the outside of the tray 3.

[0060] Optionally, the tray 3 is fixedly connected to the first door panel 2 to ensure the reliability of the connection between the two.

[0061] The battery safety test box provided in this application has a detachable first door panel 2 on one side of the box body 1, and a tray 3 connected to the first door panel 2. The tray 3 has a bearing surface that can be used to support and install functional components. When the first door panel 2 is opened, the first door panel 2 is separated from the box body 1, and a part of the tray 3 can be pulled to move to the outside of the box body 1, thereby moving the functional components mounted on it to the outside of the box body 1. At this time, the disassembly and replacement of functional components can be carried out without being affected by the box body 1, so that the staff can disassemble and replace the functional components. After the functional components are replaced, pushing the first door panel 2 can push the functional components along with the tray 3 into the box body 1 for battery safety testing. This can effectively reduce the operation difficulty for the staff and improve the convenience of replacing functional components.

[0062] Optionally, a handle 21 is provided on the side of the first door panel 2 away from the tray 3, so that the staff can pull the first door panel 2 to move the tray 3.

[0063] like Figures 3 to 5 As shown in the embodiment of this application, the battery safety test box includes a first partition 4, which is disposed inside the box body 1 and is parallel to and spaced apart from the first door panel 2. The first partition 4 is connected to the tray 3.

[0064] The space between the first partition 4 and the first door panel 2 can be used to assemble functional components.

[0065] Optionally, the first partition 4 is fixedly connected to the support plate 3 to ensure the reliability of the connection between the two.

[0066] During the process of switching between the open and closed states of the first door panel 2, the first partition 4 is driven by the support plate 3 to reciprocate along the first direction X inside the box 1.

[0067] When the first door panel 2 is closed, the first partition 4 divides the space inside the housing 1 into two cavities. The cavity formed between the first partition 4 and the first door panel 2 is used to accommodate functional components, and the cavity on the side of the first partition 4 away from the first door panel 2 is used to accommodate the battery to be tested for battery safety testing.

[0068] The first partition 4 can provide protection for the functional components. In the event of a battery fire or even explosion during battery safety testing, the functional components can be effectively protected.

[0069] like Figures 3 to 5As shown in the embodiment of this application, the battery safety test box has a plurality of through holes 41 extending along the first direction X on the first partition 4. Each through hole 41 can serve as a buffer hole. When the battery under test explodes during battery safety testing, the through holes 41 can provide flow space for the impact airflow generated by the explosion, thereby reducing the impact force on the box body 1 and the first partition 4.

[0070] Multiple perforations 41 are spaced apart along the second direction Y and / or the third direction Z.

[0071] Optionally, multiple perforations 41 are arranged in a matrix along the second direction Y and the third direction Z to form a uniform buffer channel on the first partition 4, allowing the impact airflow to pass through the first partition 4 evenly, ensuring the airflow buffering effect and improving the uniformity of the force on the first partition 4.

[0072] like Figures 3 to 5 As shown in the embodiment of this application, the battery safety test box includes a second partition 5, which is disposed between the first partition 4 and the first door panel 2. The second partition 5 is parallel to and spaced apart from the first partition 4 and the first door panel 2, respectively. The second partition 5 divides the space between the first partition 4 and the first door panel 2 into two parts, forming a buffer space between the second partition 5 and the first partition 4 to provide flow space for the impact airflow generated by the explosion of the battery under test. The second partition 5 and the first door panel 2 form an installation space for installing functional components. By setting the second partition 5, it is possible to provide flow space for the impact airflow while protecting the functional components and reducing the impact damage to the functional components caused by the impact airflow.

[0073] Optionally, the second partition 5 is fixedly connected to the support plate 3 to ensure the reliability of the connection between the two.

[0074] Optionally, the second partition 5 is detachably connected to the tray 3. Before disassembling and assembling the functional components, the second partition 5 can be removed to provide workers with more operating space and improve the ease of disassembling and assembling the functional components.

[0075] like Figures 3 to 5 As shown in the embodiment of this application, the battery safety test box has a second partition 5 with a dimension along the second direction Y that is smaller than the first partition 4 with a dimension along the second direction Y, and the second direction Y is perpendicular to the support plate 3.

[0076] The dimension of the first partition 4 along the second direction Y is slightly smaller than the dimension of the inside of the box 1 along the second direction Y, and the dimension of the first partition 4 along the third direction Z is slightly smaller than the dimension of the inside of the box 1 along the third direction Z, so as to ensure the separation effect of the first partition 4. At the same time, during the reciprocating movement of the first partition 4 with the tray 3 and the first door panel 2, the contact friction between the first partition 4 and the box 1 is reduced.

[0077] Since the functional components are mounted on the tray 3, and the size of the functional components along the second direction Y is smaller than the size of the housing 1 along the second direction Y, the size of the second partition 5 along the second direction Y can be appropriately reduced. This allows the second partition 5 to provide shielding protection for the functional components while reducing interference or obstruction to the installation of the functional components.

[0078] like Figure 4 As shown in the embodiment of this application, the battery safety test box further includes two side baffles 7. The two side baffles 7 are parallel to each other and spaced apart along the third direction Z. The two side baffles 7 are respectively connected to the two sides of the tray 3 along the third direction Z, the two sides of the first partition 4 along the third direction Z, and the first door panel 2. By setting the two side baffles 7 to be connected to the first partition 4, the tray 3 and the first door panel 2 respectively, a drawer-like structure is formed, which indirectly increases the connection strength between the tray 3 and the first door panel 2 and can effectively improve the support capacity of the tray 3.

[0079] When the first door panel 2 is closed, both side panels 7 are located inside the box 1. When the first door panel 2 is open, at least a portion of the side panels 7 are located outside the box 1.

[0080] like Figure 5 and Figure 6 As shown in the embodiment of this application, the battery safety test box has a second opening 12 on the second side of the box body 1 along the first direction X, and the first opening 11 and the second opening 12 are arranged opposite to each other; the second opening 12 is used for the battery to be tested to enter and exit the box body 1.

[0081] The battery safety test chamber includes a second door panel 6, which is detachably connected to the chamber body 1 and seals the second opening 12. The chamber body 1, the first door panel 2, and the second door panel 6 together form a sealed space for battery safety testing.

[0082] like Figure 5 , Figure 7 and Figure 8 As shown in the embodiment of this application, the battery safety test box has a transparent window 61 on the second door panel 6. During battery safety testing, the transparent window 61 allows staff to observe the battery under test in real time, improving the safety of staff during the battery safety testing process.

[0083] like Figure 7 and Figure 8As shown in the embodiment of this application, the battery safety test box includes a second door panel 6 comprising an inner layer panel 63 and an outer layer panel 62 stacked along a first direction X. The inner layer panel 63 has a first through hole 631, and the outer layer panel 62 has a second through hole 621. Along the first direction X, the projection of the first through hole 631 and the projection of the second through hole 621 at least partially overlap, thus forming a window opening of a transparent viewing window 61.

[0084] The second door panel 6 also includes a transparent panel 64, which is sandwiched between the inner panel 63 and the outer panel 62. The transparent panel 64 covers the first through hole 631 and the second through hole 621 to close the first through hole 631 and the second through hole 621. A transparent window 61 is formed at the position where the first through hole 631 and the second through hole 621 coincide along the first direction X projection, so that the staff can observe the battery safety test process.

[0085] like Figure 9 As shown in the embodiment of this application, the battery safety test box includes a frame structure 13, two side wall panels 14, a top wall panel 15, and a bottom wall panel 16.

[0086] The frame structure 13 is a cuboid frame structure, comprising four first beams 131, four second beams 132, and four columns 133. The first beams 131 extend along a first direction X, the columns 133 extend along a second direction Y, and the second beams 132 extend along a third direction Z. One end of each first beam 131 is fixedly connected to one end of a second beam 132 and one end of a column 133. The projections along the first direction X, the second direction Y, and the third direction Z all result in a rectangular shape for the frame structure 13. The frame structure 13 provides the mounting foundation for the two side wall panels 14, the top wall panel 15, and the bottom wall panel 16, and enhances the overall structural strength of the enclosure 1.

[0087] Two side wall panels 14 are parallel to each other and spaced apart. The two side wall panels 14 are fixedly connected to the two sides of the frame structure 13 along the third direction Z. The top wall panel 15 is connected to the side of the frame structure 13 that is farther away from the support plate 3 along the second direction Y. The bottom wall panel 16 is fixedly connected to the side of the frame structure 13 that is closer to the support plate 3 along the second direction Y. It can be understood that when the second direction Y is vertical, the top wall panel 15 is connected to the top of the frame structure 13 and the bottom wall panel 16 is connected to the bottom of the frame structure 13. The top wall panel 15, the bottom wall panel 16 and the two side wall panels 14 enclose and form a box 1 that runs through the first direction X. The first door panel 2 and the second door panel 6 can be detachably connected to the frame structure 13.

[0088] Optionally, the side wall panel 14, top wall panel 15 and bottom wall panel 16 are all double-layer panel structures with good structural strength to ensure the sealing performance of the box 1.

[0089] Optionally, the tray 3 can also serve as the inner layer 63 of the bottom wall panel 16.

[0090] Optionally, the two side baffles 7 can simultaneously serve as the inner layer 63 of the side wall panel 14.

[0091] Optionally, cushioning material is filled between the two layers of the side wall panel 14, top wall panel 15 and bottom wall panel 16 to improve the impact resistance of the box 1.

[0092] Optionally, fire-resistant material may be filled between the two layers of the side wall panel 14, top wall panel 15 and bottom wall panel 16 to improve the fire safety performance of the enclosure 1.

[0093] like Figure 5 and Figure 10 As shown in the embodiment of this application, the battery safety test box includes an inner top plate 151 and an outer top plate 152. The inner top plate 151 is fixedly connected to the frame structure 13 so that the inner top plate 151, the bottom wall plate 16, and the two side wall plates 14 enclose and form a closed structure that is open along the first direction X.

[0094] The outer top plate 152 and the inner top plate 151 are spaced apart along the second direction Y, and the outer top plate 152 is detachably connected to the frame structure 13. A wiring space is formed between the inner top plate 151 and the outer top plate 152. The inner top plate 151 is provided with a plurality of wire holes 1511. Along the second direction Y, the projection of some wire holes 1511 is located on the side of the first partition 4 facing the first door panel 2, and the projection of some wire holes 1511 is located on the side of the first partition 4 away from the first door panel 2. During assembly, the connecting wires of the functional components can pass through the wire hole 1511 projected on the side of the first partition 4 facing the first door panel 2 between the first partition 4 and the first door panel 2, and enter the wiring space. In the wiring space, the wires extend along the first direction X towards the direction close to the second door panel 6, and enter the housing 1 through the wire hole 1511 projected on the side of the first partition 4 facing the second door panel 6 to connect with the battery under test, thereby realizing the connection between the functional components and the battery under test. By setting up the wiring space, the connecting wires are effectively protected, ensuring that the battery safety test can be carried out smoothly.

[0095] Optionally, the first door panel 2, the second door panel 6, and the outer top panel 152 are all detachably connected to the frame structure 13 via pins 9. After removing the pins 9, the first door panel 2 can be separated from the frame structure 13, the second door panel 6 can be separated from the frame structure 13, and the outer top panel 152 can be separated from the frame structure 13.

[0096] Optionally, limiting rings 8 are provided on the first door panel 2, the second door panel 6, the outer top panel 152, and the frame structure 13. By simultaneously passing the pin 9 through the limiting ring 8 on the first door panel 2 and the corresponding limiting ring 8 on the frame structure 13, the first door panel 2 and the frame structure 13 can be fixed. By simultaneously inserting the pin 9 into the limiting ring 8 on the second door panel 6 and the corresponding limiting ring 8 on the frame structure 13, the second door panel 6 and the frame structure 13 can be fixed. By simultaneously inserting the pin 9 into the limiting ring 8 on the outer top panel 152 and the corresponding limiting ring 8 on the frame structure 13, the outer top panel 152 and the frame structure 13 can be fixed.

[0097] The battery safety test box provided in this application has a detachable first door panel 2 on one side of the box body 1, and a tray 3 connected to the first door panel 2. The tray 3 has a bearing surface that can be used to support and install functional components. When the first door panel 2 is opened, the first door panel 2 is separated from the box body 1, and a part of the tray 3 can be pulled to move to the outside of the box body 1, thereby moving the functional components installed on it to the outside of the box body 1. At this time, the disassembly and replacement of functional components can be carried out without being affected by the box body 1, so that the staff can disassemble and replace the functional components. After the functional components are replaced, pushing the first door panel 2 can push the functional components along with the tray 3 into the box body 1 for battery safety testing.
