[0029] In the related art, most battery boxes do not have a harmful gas collection device. Therefore, when an accident occurs in the battery box and harmful gases are generated, the harmful gases can only be allowed to evaporate naturally without any response measures, which poses a great safety hazard. Although a few battery boxes have a harmful gas collection device, the harmful gas collection device is an independent module, which not only occupies a large space, but also leads to a high overall production cost.

[0030] In order to solve the problems in the related art, the embodiment of the present application provides a battery box 1000. Please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 , Figure 1 1 is a schematic diagram of the structure of a battery box 1000 provided in an embodiment of the utility model. Figure 2 10 is a schematic diagram of the structure of the box 1010 provided in the embodiment of the utility model. Figure 3 10 is a schematic diagram of the connection structure between the gas processing component 1030 and the pipeline 1022 provided in an embodiment of the utility model. Figure 4 yes Figure 3 Schematic diagram of explosion structure. The battery box 1000 includes: multiple battery cells (not shown in the figure); a box body 1010, which is provided with a battery cell compartment 1011 for installing multiple battery cells, and multiple box body air outlets 1012 connected to the battery cell compartment 1011; and an air suction component 1020, including an air suction piece 1021 and a pipe 1022; wherein, the outer side of the pipe 1022 is provided with multiple pipe air inlets 1023, each pipe air inlet 1023 is connected to the corresponding box body air outlet 1012, and one end of the pipe 1022 is provided with a pipe air outlet 1024 connected to the multiple pipe air inlets 1023; the air suction piece 1021 is installed at one end of the pipe 1022, so that the harmful gas generated by at least one battery cell is sucked from the box body 1010 into the pipe 1022. Multiple pipes 1022 are arranged at intervals on the box 1010, and the distance between two adjacent pipes 1022 is consistent with the distance between two adjacent box air outlets 1012 on the box 1010 in a direction perpendicular to the extension direction of the pipes 1022. The pipe air inlets 1023 on each pipe 1022 are also arranged at intervals.

[0031] The present application does not limit the distance between two adjacent pipes 1022. The above examples are only for more clearly and comprehensively demonstrating the core ideas and methods of the present invention so as to better understand the implementation methods of the present invention. They are by no means intended to limit the scope of the present invention. Any obvious modifications or equivalent substitutions made without departing from the essence of the present invention should be deemed to be within the scope of protection of the present invention.

[0032] Among them, when at least one battery cell in the battery cell compartment 1011 accidentally generates harmful gas, the explosion-proof valve (not shown in the figure) corresponding to the battery cell will be blown open first, so that the harmful gas enters the pipeline 1022 from the explosion-proof valve through the corresponding box air outlet 1012 and the pipeline air inlet 1023, and finally the harmful gas is discharged from the battery box 1000 through the air suction part 1021.

[0033] Compared with the related art, this embodiment installs the air intake assembly 1020 on the box 1010, connects the multiple pipe air inlets 1023 located on the outer side of the pipe 1022 with the corresponding box air outlet 1012, and arranges the air intake member 1021 at one end of the pipe 1022, so that the harmful gas generated by the battery cell can be sucked from the box 1010 into the pipe 1022, thereby reducing the risk of gas pollution and ensuring the safety of the battery box 1000. In addition, the air intake assembly 1020 in this embodiment occupies a small space, which helps to reduce the material cost of the battery box 1000 during production.

[0034] In some embodiments, please refer to Figure 1 , one end of the pipe 1022 is bent and located on one side of the box 1010, and the other end of the pipe 1022 is located on the box. Among them, the air suction member 1021 is installed at the bent end of the pipe 1022. In this embodiment, the bent end of the pipe 1022 is located on one side of the box 1010, and the other end of the pipe 1022 is also located on the box, so that the overall structure of the pipe 1022 is close to the box 1010, reducing the overall space occupancy rate after the pipe 1022 is combined with the box 1010, thereby facilitating the subsequent installation of other components.

[0035] In some embodiments, please refer to Figure 5 as well as Figure 6 , Figure 5 1 is a schematic diagram of the structure of the air intake assembly 1020 provided in an embodiment of the utility model. Figure 6 yes Figure 5 The enlarged schematic diagram of part A in the figure. A boosting hole 1025 is also provided at the other end of the pipe 1022. The boosting hole 1025 is located at one end of the multiple pipe air inlets 1023 away from the air suction component 1021 and is connected to the multiple pipe air inlets 1023; the pool box 1000 also includes a gas booster (not shown in the figure), which is used to pressurize the harmful gas. The above-mentioned gas booster can be various types of air boosting devices, and the boosting pipeline of the gas booster is connected to the boosting hole 1025, and the diameter of the boosting hole 1025 is equal to the diameter of the boosting pipeline of the gas booster. In this embodiment, the boosting hole 1025 is provided at the other end of the pipe 1022, and the gas in the pipe 1022 is pressurized in cooperation with the gas booster, so that the gas flow rate in the pipe 1022 is accelerated, and the air suction efficiency of the air suction component 1020 for harmful gases is improved.

[0036] In some embodiments, please refer to Figure 4 as well as Figure 7 , Figure 71 is a schematic diagram of the structure of the pipe 1022 in the air suction assembly 1020 provided in an embodiment of the utility model. A support portion 1027 is provided at one end of the pipe 1022, and the air suction member 1021 is installed on the support portion 1027. The support portion 1027 is provided with a hollow hole 1028 to connect the pipe air outlet 1024 and the plurality of pipe air inlets 1023. Specifically, the air suction member 1021 can be fixed on the support portion 1027 by bolts, or can be fixed on the support portion 1027 by other means.

[0037] It should be noted that the present application does not limit the fixing method of the air suction part 1021. The above examples are only for more clearly and comprehensively demonstrating the core ideas and methods of the present invention so as to better understand the implementation methods of the present invention. They are by no means intended to limit the scope of the present invention. Any obvious modifications or equivalent substitutions made without departing from the essence of the present invention should be deemed to be within the scope of protection of the present invention.

[0038] In this embodiment, the air suction member 1021 is fixed on the support portion 1027 , so that the air suction member 1021 sucks the harmful gas in the pipeline 1022 and discharges it from the pipeline outlet 1024 through the hollow hole 1028 on the support portion 1027 .

[0039] In some embodiments, please refer to Figure 4 The air suction member 1021 includes a fan 1026 , the orthographic projection of the blades of the fan 1026 on the support portion 1027 is located within the boundary of the hollow hole 1028 , and the area swept by the blades of the fan 1026 when the blades rotate is smaller than the area of ​​the hollow hole 1028 .

[0040] In this embodiment, the orthographic projection of the fan blades of the fan 1026 on the support portion 1027 is located within the boundary of the hollow hole 1028, and the area swept by the fan blades when the fan blades of the fan 1026 rotate is smaller than the area of ​​the hollow hole 1028, so that the suction efficiency of the air suction member 1021 is higher and the production cost of the air suction member 1021 is reduced. If the orthographic projection of the fan blades of the fan 1026 on the support portion 1027 is not completely located within the boundary of the hollow hole 1028, and the area swept by the fan blades when the fan blades of the fan 1026 rotate is larger than the area of ​​the hollow hole 1028, the suction efficiency of the air suction member 1021 will not be significantly improved compared to the suction efficiency of the air suction member 1021 in this embodiment, but the production cost of the fan 1026 of the air suction member 1021 will be increased due to the increase in the blade area of ​​the fan 1026.

[0041] In some embodiments, please refer to Figure 3 as well as Figure 4The battery box 1000 further includes a gas treatment component 1030 for treating harmful gases. One end of the gas treatment component 1030 is mounted on one end of the pipeline 1022 , and the other end of the gas treatment component 1030 is provided with a gas treatment outlet 1031 communicating with the pipeline outlet 1024 .

[0042] In this embodiment, one end of the gas treatment component 1030 is installed at one end of the pipeline 1022 to treat harmful gases. Specifically, at least one filter layer structure (not shown in the figure) is provided inside the end of the gas treatment component 1030 close to the gas treatment outlet 1031. The filter layer structure can be activated carbon or other chemical reagents, and different materials of the filter layer structure can be set according to specific circumstances. The filter layer structure physically adsorbs or chemically treats the harmful gases passing through, so that the harmful gases become harmless gases or liquids after passing through the filter layer structure, and finally are discharged from the gas treatment outlet 1031.

[0043] It should be noted that the present application does not limit the material of the filter layer structure. The above examples are only for more clearly and comprehensively demonstrating the core ideas and methods of the present invention, so as to better understand the implementation methods of the present invention. They are by no means intended to limit the scope of the present invention. Any obvious modifications or equivalent substitutions made without departing from the essence of the present invention should be deemed to be within the scope of protection of the present invention.

[0044] In some embodiments, one end of the pipe 1022 is provided with a first skirt 1033 surrounding the pipe gas outlet 1024, and the gas treatment component 1030 is fixed to the first skirt 1033. Correspondingly, the end of the gas treatment component 1030 close to the pipe 1022 is also provided with a second skirt 1034, which is used to cooperate with the first skirt 1033 to fix the gas treatment component 1030. It should be noted that the first skirt 1033 and the second skirt 1034 can be fixed by bolts, or by other methods to achieve the fixation between the gas treatment component 1030 and the pipe 1022. The present application does not limit the fixing method. The above examples are only for more clear and comprehensive demonstration of the core ideas and methods of the utility model, so as to better understand the implementation methods of the utility model, and are by no means to limit the scope of the utility model. Any obvious modification or equivalent replacement made without departing from the essence of the utility model should be regarded as within the protection scope of the utility model.

[0045] In some embodiments, please refer to Figure 1, the other end of the gas treatment component 1030 is bent and lower than the pipe 1022. In this embodiment, by setting the other end of the gas treatment component 1030 to be a bent structure and lower than the pipe 1022, the function is that when the harmful gas passes through the filter layer structure, liquid may be generated, and the liquid will pass through several layers of filter layer structures and finally flow out from the last filter layer structure. Due to the existence of the bend of the gas treatment component 1030 and the bend direction is obliquely downward, when the liquid is generated, it will flow downward along the wall of the gas treatment component 1030 due to gravity factors, and finally the liquid is discharged through the gas treatment outlet 1031.

[0046] In this embodiment, the other end of the gas treatment component 1030 is configured as a bent structure and is lower than the pipeline 1022, which can not only discharge the filtered harmful gas, but also discharge the liquid generated by the harmful gas passing through the filter layer structure.

[0047] The embodiment of the utility model provides a battery box 1000. Compared with the related art, the solution of the utility model is to install an air suction component 1020 on the box body 1010, connect multiple pipe air inlets 1023 located on the pipe body 1022 with the corresponding box body air outlets 1012, and set an air suction piece 1021 at one end of the pipe 1022, so that harmful gases generated by the battery cells can be sucked into the pipe 1022 from the box body 1010, thereby reducing the risk of gas pollution and ensuring the safety of the battery box 1000.

[0048] The embodiment of the utility model also provides a battery system, including the above-mentioned battery box 1000, wherein the box body has multiple rows of battery compartments, the number of air intake components is multiple, each row of battery compartments is provided with a corresponding air intake component, and the battery system also includes electrical components electrically connected to the battery box, such as a controller, wires, etc. Among them, the controller is used to control the charging and discharging process of the battery box to ensure the safety, stability and performance of the battery box. The wires are used to connect the battery box and electrical components such as the controller. The battery system has all the advantages of the above-mentioned battery box 1000, which will not be repeated here.
