[0034] Reference below Figure 1-Figure 6 A battery pack assembly 100 according to an embodiment of the utility model is described. The high-temperature gas generated by the battery pack 1 can be discharged through the explosion-proof valve 11, and a protective cover 2 is provided to protect the explosion-proof valve 11, thereby improving the reliability of the operation of the explosion-proof valve 11. At the same time, a connecting port 21 is provided on the explosion-proof valve 11, and the connecting port 21 is connected to the exhaust pipe 3 through an exhaust clamp 4 to ensure smooth discharge of the high-temperature gas, and the connection method is simple and reliable. In addition, a safety deflector 5 is provided at the exhaust port 34 to guide the high-temperature gas, thereby effectively reducing the possibility of thermal runaway of the battery pack 1.

[0035] like Figure 1 As shown, a battery pack assembly 100 according to an embodiment of the present invention includes: a battery pack 1, a protective cover 2, an exhaust pipe 3 and an exhaust clamp 4.

[0036] The battery pack 1 is provided with an explosion-proof valve 11 .

[0037] Specifically, the battery pack 1 is used to store electrical energy to provide power for the vehicle. The battery pack 1 will generate high-temperature gas during operation. An explosion-proof valve 11 is provided on the battery pack 1. The explosion-proof valve 11 is used to open when the pressure inside the battery pack 1 is too high or the temperature is too high, so that the high-temperature gas inside the battery pack 1 can be discharged therefrom, so as to reduce the possibility of thermal runaway of the battery pack 1.

[0038] The protective cover 2 is arranged outside the explosion-proof valve 11, and the protective cover 2 has a connecting port 21, which is plugged and connected to the exhaust pipe 3, and the exhaust clamp 4 is sleeved at the connecting position between the connecting port 21 and the exhaust pipe 3. The other end of the exhaust pipe 3 is formed with an exhaust port 34, and the exhaust port 34 is connected to the safety guide cover 5, and the safety guide cover 5 is formed with a guide outlet 52.

[0039] Specifically, a protective cover 2 is provided in the battery pack assembly 100, and the protective cover 2 is provided outside the explosion-proof valve 11, so that the protective cover 2 can be used to protect the explosion-proof valve 11, so as to prevent the explosion-proof valve 11 from being damaged and failing due to collision, thereby improving the reliability of the explosion-proof valve 11, and a connecting port 21 is provided on the protective cover 2, so that the high-temperature gas generated by the battery pack 1 can enter the interior of the protective cover 2 from the explosion-proof valve 11 and be discharged through the connecting port 21. At the same time, one end of the exhaust pipe 3 is connected to the connecting port 21, and the other end forms an exhaust port 34, so that the high-temperature gas can enter the exhaust pipe 3 from the connecting port 21, and flow along the exhaust pipe 3 to the exhaust port 34 to be discharged. Through this process, the reliability of discharging the high-temperature gas can be improved, and the possibility of thermal runaway of the battery pack 1 can be effectively reduced.

[0040] Among them, when the connecting port 21 is connected to one end of the exhaust pipe 3, the connecting port 21 can be sleeved on the outside of one end of the exhaust pipe 3, or one end of the exhaust pipe 3 can be sleeved on the outside of the connecting port 21, so as to increase the connection length between the two and improve the connection reliability between the two, and the exhaust clamp 4 can be sleeved on the connecting port 21 and the exhaust pipe 3. That is, when the connecting port 21 is sleeved on the outside of one end of the exhaust pipe 3, the exhaust clamp 4 can be sleeved on the outside of the connecting port 21, or when one end of the exhaust pipe 3 is sleeved on the outside of the connecting port 21, the exhaust clamp 4 can be sleeved on the outside of the exhaust pipe 3. The exhaust clamp 4 can be used to fix the connecting port 21 and the exhaust pipe 3 at the connecting position between the two, so as to further improve the connection reliability between the two and ensure the smooth discharge of high-temperature gas. The connection method is simple and easy to operate.

[0041] It should be noted that, by connecting and fixing the protective cover 2 and the exhaust pipe 3 through the exhaust clamp 4, the protective cover 2 does not need to be separately fixed to the explosion-proof valve 11 through a separate connecting piece, and the relative position of the protective cover 2 and the explosion-proof valve 11 can be fixed, that is, after the position of the exhaust pipe 3 is determined, the protective cover 2 is also fixed in the corresponding position, thereby reducing the connecting pieces between the protective cover 2 and the explosion-proof valve 11 and reducing the setting cost. At the same time, the connection through the exhaust clamp 4 is conducive to the disassembly of the protective cover 2 and the exhaust pipe 3. After the protective cover 2 is impacted and deformed by the airflow at the explosion-proof valve 11, it can be quickly disassembled and replaced.

[0042] In addition, a safety deflector 5 is provided at the exhaust port 34. The safety deflector 5 is used to guide the high-temperature gas discharged from the exhaust port 34 so that the high-temperature gas can flow in a direction away from the battery pack 1 to prevent the high-temperature gas from affecting the battery pack 1 and causing it to explode or other dangerous situations. The safety deflector 5 forms a deflection outlet 52. The deflection outlet 52 is used to allow the high-temperature gas discharged from the exhaust port 34 to be discharged therefrom, so that the discharge position of the high-temperature gas can be limited to effectively prevent the high-temperature gas from affecting the battery pack 1, and further, the high-temperature airflow at the exhaust port 34 can be guided in a specific direction in the safety deflector 5, thereby realizing active deflection of the high-temperature airflow, thereby preventing the high-temperature airflow from directly impacting a position with a higher risk of danger, thereby improving the safety of the battery pack 1 and the entire vehicle.

[0043] Therefore, by providing a battery pack 1 to provide power for the vehicle, by providing an explosion-proof valve 11, the high-temperature gas generated by the battery pack 1 during operation can be discharged to reduce the possibility of thermal runaway of the battery pack 1, and a protective cover 2 is provided outside the explosion-proof valve 11 to protect the explosion-proof valve 11 to avoid damage and failure caused by collision of the explosion-proof valve 11, thereby improving the reliability of the operation of the explosion-proof valve 11. At the same time, by providing a connecting port 21 on the protective cover 2, and connecting the connecting port 21 to the exhaust pipe 3 through the exhaust clamp 4, the high-temperature gas can enter the exhaust pipe 3 from the connecting port 21 and be discharged from the exhaust port 34, and the connection method is simple and reliable, and a safety deflector 5 is provided at the exhaust port 34 to guide the high-temperature gas discharged from the exhaust port 34 to avoid the high-temperature gas from affecting the battery pack 1.

[0044] According to the battery pack assembly 100 of the embodiment of the utility model, the high-temperature gas generated by the battery pack 1 can be discharged through the explosion-proof valve 11, and the protective cover 2 is provided to protect the explosion-proof valve 11, thereby improving the reliability of the operation of the explosion-proof valve 11. At the same time, a connecting port 21 is provided on the explosion-proof valve 11, and the connecting port 21 is connected to the exhaust pipe 3 through the exhaust clamp 4 to ensure the smooth discharge of the high-temperature gas, and the connection method is simple, reliable, and easy to operate. In addition, a safety guide cover 5 is provided at the exhaust port 34 to guide the high-temperature gas, thereby effectively reducing the possibility of thermal runaway of the battery pack 1 and improving the safety of the battery pack 1.

[0045] In some embodiments, the safety deflector 5 is provided with a deflection slope 51 , the open flow direction of the deflection outlet 52 intersects with the open direction of the exhaust port 34 , and the deflection slope 51 is used to guide the airflow at the exhaust port 34 toward the deflection outlet 52 .

[0046] Specifically, the safety deflector 5 is used to guide the high-temperature gas discharged from the exhaust port 34. A deflector slope 51 is provided on the safety deflector 5, and the deflector slope 51 can be used to guide the high-temperature gas discharged from the exhaust port 34 to prevent the high-temperature gas from flowing toward the position where the battery pack 1 is located. At the same time, the open flow direction of the deflector outlet 52 is set to intersect with the open direction of the exhaust port 34, so that the flow direction of the high-temperature gas discharged from the exhaust port 34 can intersect with the flow direction of the high-temperature gas flowing out of the deflector outlet 52, and the deflector slope 51 can guide the airflow at the exhaust port 34 to the deflector outlet 52, so that the high-temperature gas discharged from the exhaust port 34 can flow to the deflector outlet 52 under the action of the deflector slope 51 and be discharged from the deflector outlet 52.

[0047] In such Figure 3 In the embodiment shown, the safety deflector 5 is formed into a boss with a certain slope on the side through the guide slope 51 to guide the high-temperature gas. When the high-temperature gas flows from the exhaust port 34 to the bottom of the safety deflector 5, the flow direction of the high-temperature gas can be changed through the guide slope 51 to make it flow toward the guide outlet 52. In addition, a notch is provided at the bottom of the safety deflector 5, that is, the flow rate of the high-temperature gas can be increased while ensuring the guiding function.

[0048] In some embodiments, the exhaust pipe 3 includes a horizontal section 31 and a vertical section 33. One end of the horizontal section 31 is connected to the protective cover 2, and the vertical section 33 is connected to the other end of the horizontal section 31 and bends and extends downward relative to the horizontal section 31. An exhaust port 34 is formed at the lower end of the vertical section 33.

[0049] Specifically, both the horizontal section 31 and the vertical section 33 can allow the high-temperature gas to flow therein until it is discharged. The horizontal section 31 is connected to the protective cover 2, that is, the horizontal section 31 is connected to the connecting port 21, so that the high-temperature gas can enter the horizontal section 31 from the connecting port 21, and the other end of the horizontal section 31 is connected to the vertical section 33, so that the high-temperature gas can enter the vertical section 33 along the horizontal section 31. In addition, the vertical section 33 is bent downward relative to the horizontal section 31, so that the flow direction of the high-temperature gas when entering the vertical section 33 from the horizontal section 31 is changed, so that the high-temperature gas flows downward, and the exhaust port 34 is formed at the lower end of the vertical section 33, so that the high-temperature gas can pass through the vertical section 33 and be discharged from the exhaust port 34. In other words, by setting the horizontal section 31 and the vertical section 33, the high-temperature gas can enter the horizontal section 31 from the connecting port 21, enter the vertical section 33 along the horizontal section 31, and then be discharged from the exhaust port 34.

[0050] It should be noted that by setting the vertical section 33 to be bent downward from the horizontal section 31, the high-temperature gas can flow downward and be discharged, thereby ensuring the safety of living spaces such as the cab.

[0051] In some embodiments, the exhaust pipe 3 further includes an arc-shaped guide section 32 , which is connected between the horizontal section 31 and the vertical section 33 and is tangent to the horizontal section 31 and the vertical section 33 , respectively.

[0052] Specifically, the arcuate guide section 32 is connected between the horizontal section 31 and the vertical section 33, that is, the arcuate guide section 32 is used to connect the horizontal section 31 and the vertical section 33, so that the high-temperature gas in the horizontal section 31 can enter the vertical section 33 along the arcuate guide section 32 and then be discharged, so as to reduce the possibility of thermal runaway of the battery pack 1, and the arcuate guide section 32 is tangent to the horizontal section 31 and also to the vertical section 33, that is, the connection between the horizontal section 31 and the arcuate guide section 32 and the connection between the vertical section 33 and the arcuate guide section 32 are smooth, so as to ensure that the high-temperature gas flows smoothly in the exhaust pipe 3 until it is discharged.

[0053] In some embodiments, there are multiple explosion-proof valves 11 , and the protective cover 2 is formed with multiple shielding areas, and the multiple shielding areas are distributed in a one-to-one correspondence with the multiple explosion-proof valves 11 .

[0054] Specifically, the explosion-proof valve 11 is used to discharge the high-temperature gas generated by the battery pack 1 during operation. By providing a plurality of explosion-proof valves 11, the efficiency and reliability of the discharge of the high-temperature gas from the explosion-proof valve 11 can be improved. At the same time, a shielding area is formed in the protective cover 2, and the shielding area can be used to buffer the impact force exerted on the protective cover 2, so as to protect the explosion-proof valve 11 and prevent the explosion-proof valve 11 from being damaged and failing due to collision. In addition, a plurality of shielding areas are formed in the protective cover 2, and the plurality of shielding areas are made to correspond one-to-one with the plurality of explosion-proof valves 11, so that each explosion-proof valve 11 has a shielding area to protect it, thereby improving the reliability of protecting the explosion-proof valve 11.

[0055] Among them, a plurality of explosion-proof valves 11 are spaced apart and distributed on the same side of the battery pack 1 .

[0056] Specifically, the multiple explosion-proof valves 11 are spaced apart to avoid interference between the high-temperature gases discharged from each explosion-proof valve 11, thereby reducing the rate at which the high-temperature gases are discharged. At the same time, the multiple explosion-proof valves 11 are arranged on the same side of the battery pack 1. The multiple explosion-proof valves 11 can be protected simultaneously by only one protective cover 2, which can reduce the number of protective covers 2 and reduce the installation cost. Accordingly, only one connecting port 21 and one exhaust pipe 3 can be provided to discharge the high-temperature gases discharged from the multiple explosion-proof valves 11, which can further reduce the installation cost.

[0057] For example, Figure 2 As shown, two explosion-proof valves 11 are provided on the battery pack 1 to improve the efficiency of discharging the high-temperature gas generated in the battery pack 1. At the same time, the two explosion-proof valves 11 are spaced apart and placed on the same side of the battery pack 1 to avoid interference between the high-temperature gases discharged from the two explosion-proof valves 11, thereby reducing the rate of high-temperature gas discharge. A protective cover 2 can be used to protect the two explosion-proof valves 11 at the same time, which can reduce the number of protective covers 2 set, and correspondingly, the number of connection ports 21 and exhaust pipes 3 set can also be reduced. In addition, the protective cover 2 is also formed with two shielding areas to protect the two explosion-proof valves 11 one by one, thereby improving the reliability of protecting the explosion-proof valves 11.

[0058] Also, it should be noted that the exhaust pipe 3 can be made of stainless steel to reduce the corrosion of the exhaust pipe 3 by the high-temperature gas and extend the service life of the exhaust pipe 3.

[0059] The utility model also provides a floor assembly 200.

[0060] According to the floor assembly 200 of the embodiment of the utility model, it includes a vehicle body floor 201 and a battery pack assembly 100 of any one of the above-mentioned embodiments, the battery pack 1 is installed above the vehicle body floor 201, the exhaust pipe 3 passes through the vehicle body floor 201 and the exhaust port 34 is open below the vehicle body floor 201.

[0061] Specifically, the battery pack 1 is installed above the vehicle body floor 201, and the battery pack 1 can be connected to the vehicle body floor 201 to install and fix the battery pack 1 to prevent the battery pack 1 from moving or shaking during the driving of the vehicle and causing damage and failure. At the same time, the exhaust pipe 3 is passed through the vehicle body floor 201, so that the high-temperature gas can flow from one side of the vehicle body floor 201 along the exhaust pipe 3 to the other side of the vehicle body floor 201, and the exhaust port 34 is opened below the vehicle body floor 201, so that the high-temperature gas can flow from the top of the vehicle body floor 201 to the bottom and be discharged. The vehicle body floor 201 can be used to shield the battery pack 1, further preventing the high-temperature gas from flowing to the area where the battery pack 1 is located, and effectively reducing the possibility of thermal runaway of the battery pack 1.

[0062] In some embodiments, the safety deflector 5 is connected to the vehicle body floor 201 and is located below the vehicle body floor 201 . The safety deflector 5 is disposed outside the exhaust port 34 .

[0063] Specifically, the safety air deflector 5 is used to guide the high-temperature gas. By connecting the safety air deflector 5 to the vehicle body floor 201, the safety air deflector 5 can be installed and fixed to improve the reliability of guiding the high-temperature gas. At the same time, by connecting the safety air deflector 5 to the bottom of the vehicle body floor 201, the safety air deflector 5 and the exhaust port 34 can be set on the same side of the vehicle body floor 201, and by setting the safety air deflector 5 outside the exhaust port 34, the safety air deflector 5 can be used to guide the high-temperature gas discharged from the exhaust port 34 to avoid the high-temperature gas from affecting the battery pack 1.

[0064] In some embodiments, a fuel tank installation area is formed on the vehicle body floor 201 , and the guide outlet 52 is configured to open in a direction away from the fuel tank installation area.

[0065] Specifically, the oil tank installation area is used to provide an installation position for the oil tank 203, that is, the oil tank 203 can be installed in the oil tank installation area, and the diversion outlet 52 is constructed to be open in the direction away from the oil tank installation area, that is, the diversion outlet 52 is open in the direction away from the oil tank 203, so that the high-temperature gas flows in the direction away from the oil tank 203, so as to ensure the safety of the oil tank 203.

[0066] In such Figure 4-Figure 6In the illustrated embodiment, the battery pack 1 and the fuel tank 203 are respectively mounted on the two sides of the vehicle body floor 201, that is, the fuel tank 203 and the exhaust port 34 are arranged on the same side of the vehicle body floor 201, and the vehicle body floor 201 can be used to shield the battery pack 1 to prevent high-temperature gas from flowing toward the location of the battery pack 1, thereby reducing the possibility of thermal runaway of the battery pack 1, and the diversion outlet 52 is opened in the direction away from the fuel tank 203, and the diversion slope 51 can be used to make the high-temperature gas flow in the direction away from the fuel tank 203, thereby ensuring the safety of the fuel tank 203.

[0067] In some embodiments, the vehicle body floor 201 is further provided with an exhaust reinforcement plate 202 , and the exhaust pipe 3 penetrates through the exhaust reinforcement plate 202 and is connected to the exhaust reinforcement plate 202 .

[0068] Specifically, the exhaust reinforcement plate 202 is used to improve the structural rigidity of the vehicle body floor 201. The vehicle body floor 201 and the exhaust reinforcement plate 202 can be connected by welding to improve the connection strength between the two, thereby improving the reliability of enhancing the structural rigidity of the vehicle body floor 201. At the same time, the exhaust pipe 3 passes through the exhaust reinforcement plate 202, so that the high-temperature gas in the exhaust pipe 3 can flow from one side of the exhaust reinforcement plate 202 to the other side, that is, from the top to the bottom of the exhaust reinforcement plate 202. In addition, the exhaust pipe 3 is connected to the exhaust reinforcement plate 202, so that the end of the exhaust pipe 3 where the exhaust port 34 is located can be fixed to limit the flow direction of the high-temperature gas.

[0069] It should be noted that a waterproof nut can be welded on the exhaust reinforcement plate 202, and a connecting hole can be set at one end of the exhaust pipe 3 where the exhaust port 34 is located, so that the exhaust pipe 3 passes through the vehicle body floor 201 and is connected to the exhaust reinforcement plate 202 by screwing.
