Specifically, when thermal runaway occurs in the battery cell 50 in the accommodating space 25 and a high-temperature and high-pressure fire flow is generated, the high-temperature and high-pressure fire flow in the accommodating space 25 may firstly enter the first exhaust channel 34 on at least one of the left threshold beam 21 and the right threshold beam 22, then flow from the first exhaust channel 34 to the second exhaust channel 261, and finally flow from the air outlet 262 on the second exhaust channel 261 to the external environment. In addition, the path of the high-temperature and high-pressure gas-fire flow from the accommodating space 25 to the outside can be shortened, and the exhaust efficiency can be improved.

As shown in fig. 5 to 7, the air outlet 262 is angled with respect to the vertical direction of the vehicle 100 to discharge the air stream obliquely downward after the thermal runaway of the battery cell 50. Specifically, by disposing the air outlet 262 at an angle to the vertical direction of the vehicle 100, the high-temperature and high-pressure air-fire flow can be discharged obliquely downward, the high-temperature and high-pressure air-fire flow will not flow back into the second exhaust passage 261 in the reverse direction obliquely downward, and secondary damage to vehicle occupants and external articles will not be caused by parallel ejection with the road surface, so that the air outlet stability of the second exhaust passage 261 can be further improved, and the reliability of the vehicle 100 can be further improved.

In another embodiment of the present invention, as shown in fig. 5, the adapter 26 is integrally formed with at least one of the left and right rocker beams 21, 22 and is located on an outer side wall of at least one of the left and right rocker beams 21, 22, so that the installation of the adapter 26 is facilitated while the air outlet 262 of the adapter 26 is ensured to be inclined downward, thereby facilitating the production of the vehicle 100.

As shown in connection with fig. 7, the air outlet 262 is provided on an outer side wall of the adaptor 26, which outer side wall of the adaptor 26 extends at least partially obliquely downward in the outward-inward direction.

Further, the outer side wall of the adaptor 26 at least partially extends obliquely downward in the direction from outside to inside, and thus the air outlet 262 is directly formed in the adaptor 26, so that the air outlet 262 can be discharged obliquely downward, and the structural design of the vehicle 100 can be simplified on the premise that the high-temperature and high-pressure air and fire flow is ensured to be stably and continuously discharged obliquely downward. In addition, after the high-temperature and high-pressure gas stream is discharged from the gas outlet 262, the adaptor 26 can block the high-temperature and high-pressure gas stream, so that the influence of the high-temperature and high-pressure gas stream on the adaptor 26 can be prevented, and the reliability of the vehicle 100 can be improved.

Further, the included angle between the outer side wall of the adapter 26 and the vertical direction of the vehicle is α, and α satisfies the relation: alpha is more than or equal to 15 degrees and less than or equal to 75 degrees.

Further, as shown in fig. 6, at least one of the left and right rocker beams 21 and 22 is provided with a reinforcement portion 36, the reinforcement portion 36 may partition the first exhaust passage 34 in at least one of the left and right rocker beams 21 and 22 into a plurality of first sub-exhaust passages 341, the guide portion 2612 is located between the reinforcement portion 36 and the air outlet 262, and the flow of the gas and fire may pass through the sub-exhaust passages 341 and then be guided to the air outlet 262 by the guide portion 2612, so that not only the structural strength of the left and right rocker beams 21 and 22 may be further improved, but also the reliability of the exhaust gas may be improved.

Further, as shown in fig. 5, the left and right threshold beams 21 and 22 are provided with the lap joint 43, and after the inner partition beam 40 is lapped on the lap joint 43 of the left and right threshold beams 21 and 22, the lap joint may be fixed by bolts or by welding, so that the left and right threshold beams 21 and 22 are connected and fixed to the inner partition beam 40, and further, the lap joint 43 is provided with the glue groove 44, and the glue groove 44 is filled with the sealant, so that the air leakage between the left and right threshold beams 21 and 22 and the inner partition beam 40 can be prevented, and the structural reliability of the vehicle 100 can be improved.

Further, a plurality of adapters 26 are arranged on at least one of the left threshold beam 21 and the right threshold beam 22 at intervals, and therefore the air outlets 262 on the adapters 26 are arranged on at least one of the left threshold beam 21 and the right threshold beam 22 at intervals, so that the exhaust volume of the vehicle 100 in unit time can be improved, the exhaust of the air outlets 262 can be more uniform, and the stability and the reliability of the exhaust of the vehicle 100 can be further improved.

Further, by leaving the second gap 54 between at least one of the left and right threshold beams 21 and 22 and the battery cell 50 and communicating the first gap 53 and the second gap 54, not only the contact area between the battery cell 50 and the air can be further increased, the contact area between the battery cell 50 and the air can be increased, but also when the battery cell 50 is out of control due to heat and high-temperature and high-pressure fire flows are generated, the high-temperature and high-pressure fire flows can enter the second gap 54 from the first gap 53 and then enter the first exhaust channel 34 from the second gap 54 through the air inlet 221, so that the stability and smoothness of the high-temperature and high-pressure fire flows entering the first exhaust channel 34 can be further increased, and the exhaust efficiency can be improved to a certain extent.

In addition, since the at least two inner partition beams 40 divide the accommodating space 25 into the plurality of sub-accommodating spaces 251, the volume of each sub-accommodating space 251 is small, that is, the number of the battery cells 50 in each sub-accommodating space 251 is small, so that when a fire occurs in one of the sub-accommodating spaces 251, the loss of a plurality of battery cells 50 can be further reduced due to the small number of the battery cells 50 in the sub-accommodating space 251.

In other embodiments, the inner beams 40 are at least two, and are longitudinal beams 42, two ends of at least two longitudinal beams 42 are respectively connected to the front beam 23 and the rear beam 24, and are arranged at intervals in the left-right direction, so that the accommodating space 25 is divided into a plurality of sub-accommodating spaces 251 arranged in the left-right direction, and thus the plurality of battery cells 50 can be divided into at least three parts in the left-right direction, which not only can further increase the contact heat exchange area of the plurality of battery cells 50 with the inner beams 40, but also can improve the heat exchange performance of the plurality of battery cells 50, and when a high-temperature fire occurs in a battery cell 50 in a certain sub-accommodating space 251, because the plurality of battery cells 50 are divided into at least three parts, the inner beams 40 can separate the sub-accommodating space 251 of the battery cell 50 where the high-temperature fire occurs from the battery cells 50 in other sub-accommodating spaces 251, the loss can be reduced. In addition, since the at least two inner partition beams 40 divide the accommodating space 25 into the plurality of sub-accommodating spaces 251, the volume of each sub-accommodating space 251 is small, that is, the number of the battery cells 50 in each sub-accommodating space 251 is small, so that when a fire occurs in one of the sub-accommodating spaces 251, the loss of a plurality of battery cells 50 can be further reduced due to the small number of the battery cells 50 in the sub-accommodating space 251.

In other embodiments, as shown in fig. 1 and 2, the number of the inner beams 40 is at least two, and the inner beams are a cross beam 41 and a longitudinal beam 42, the cross beam 41 and the longitudinal beam 42 are arranged in an intersecting manner, two ends of the cross beam 41 are respectively connected to the left threshold beam 21 and the right threshold beam 22 and are arranged at intervals in the front-rear direction, two ends of the longitudinal beam 42 are respectively connected to the front cross beam 23 and the rear cross beam 24 and are arranged at intervals in the left-right direction, so that the accommodating space 25 can be divided into a plurality of sub-accommodating spaces 251 which are uniformly arranged at intervals in the left-right direction and the front-rear direction, so that the plurality of battery cells 50 can be divided into at least four parts, thereby not only further increasing the contact heat exchange area of the plurality of battery cells 50 with the inner beam 40 and improving the performance of the plurality of battery cells 50, but also when a high temperature occurs in a certain heat exchange sub-accommodating space 251, since the plurality of battery cells 50 are partitioned into at least four parts, the inner partition beams 40 may partition the sub-receiving space 251 of the battery cell 50, in which a high-temperature fire occurs, from the battery cells 50 in other sub-receiving spaces 251, and may reduce loss.

In addition, since the at least two inner partition beams 40 divide the accommodating space 25 into the plurality of sub-accommodating spaces 251, the volume of each sub-accommodating space 251 is small, that is, the number of the battery cells 50 in each sub-accommodating space 251 is small, so that when a fire occurs in one of the sub-accommodating spaces 251, the loss of a plurality of battery cells 50 can be further reduced due to the small number of the battery cells 50 in the sub-accommodating space 251. It should be noted that, with such an arrangement, on the premise that the number of the inner partition beams 40 is the same, the number of the sub-accommodation spaces 251 into which the accommodation space 25 is partitioned by the inner partition beams 40 can be increased, so that on the premise that the number of the plurality of battery cells 50 is fixed, the number of the battery cells 50 in each sub-accommodation space 251 can be further reduced.

Further, the number of the inner barrier beams 40 and the arrangement manner in the accommodating space 25 may be selectively set according to the specific structure and the specific process requirements of the vehicle 100, so that the applicability of the inner barrier beams 40 may be further improved, and thus the reliability of the vehicle 100 may be further improved.

It should be noted that, when the inner partition beams 40 are the transverse partition beams 41 and the longitudinal partition beams 42, the number of the transverse partition beams 41 and the number of the longitudinal partition beams 42 may be different, and the number of the transverse partition beams 41 and the number of the longitudinal partition beams 42 may be adjusted according to specific process requirements, so that the variability and flexibility of the installation and the arrangement of the inner partition beams 40 in the accommodating space 25 may be improved, and the applicability of the inner partition beams 40 may be improved.

As shown in fig. 4, the plurality of battery cells 50 are respectively disposed in the at least two sub-receiving spaces 251, and a third gap 55 is left between the plurality of battery cells and the inner partition beam 40, and the third gap 55 is communicated with the second gap 54. Specifically, by leaving the third gap 55 between the inner spacer bar 40 and the adjacent battery cell 50 in the adjacent column, the contact area between the plurality of battery cells 50 and the air can be increased, and thus the heat dissipation performance of the plurality of battery cells 50 can be improved. Further, the third gap 55 is communicated with the second gap 54, so that when thermal runaway occurs in the battery cells 50 in a row adjacent to the inner partition beam 40, the gas fire flow can rapidly and directly enter the second gap 54 through the third gap 55 and then directly enter the first exhaust channel 34 from the second gap 54 through the air inlet 221, and therefore, not only can the exhaust efficiency be further improved, but also the exhaust of the accommodating space 25 can be more uniform, the uniformity of the air pressure in the accommodating space 25 can be improved, and the reliability of the accommodating space 25 can be improved.

As shown in fig. 2, each sub-receiving space 251 corresponds to a plurality of air inlets 221, and corresponds to one air outlet 262. Specifically, since the second gap 54 has a certain length, after the high-temperature and high-pressure gas fire flows enter the second gap 54, the second gap 54 of each sub-receiving space 251 corresponds to the plurality of air inlets 221, so that not only can uniformity of the high-temperature and high-pressure gas fire flows in the second gap 54 entering the exhaust passage 211 through the air inlets 221 be ensured, but also the air intake efficiency can be improved.

Further, the second gap 54 of each sub-receiving space 251 corresponds to one air outlet 262, so that a certain pressure can be ensured when the high-temperature and high-pressure fire stream in the second air outlet channel 261 is discharged from the air outlet 262, and the high-temperature and high-pressure fire stream can be ejected from the air outlet 262 at a certain speed, thereby not only improving the air outlet efficiency, but also preventing the high-temperature and high-pressure fire stream from flowing back to the air outlet channel 211, and thus improving the stability and reliability of the exhaust.

As shown in fig. 2-5, the outlet area of the outlet 262 is larger than the inlet area of the inlet 221. In particular, since each sub-receiving space 251 corresponds to a plurality of air inlets 221, and to one air outlet 262, if the inlet area of the single inlet 221 is set equal to the outlet area of the outlet 262, the amount of the high-temperature, high-pressure fire flow entering the first exhaust passage 34 per unit time will be larger than the amount flowing out from the second exhaust passage 261, this causes unevenness of intake and exhaust, which causes a long-term charge of the high-temperature and high-pressure ignition current accumulated in the first exhaust passage 34 and the second exhaust passage 261, resulting in a failure of the high-temperature and high-pressure ignition current in the second gap 54 to smoothly enter the first exhaust passage 34, therefore, the air outlet area of the air outlet 262 is set to be larger than the air inlet area of the air inlet 221, this can improve the smoothness of the air intake and exhaust of the first exhaust passage 34, so that the reliability of the first exhaust passage 34 can be improved.

In some embodiments, the air inlet 221 is provided with a cover 2211, and the cover 2211 is openably and closably provided to the air inlet 221.

In other embodiments, a breakable weakening structure is provided between the cover 2211 and the air inlet 221. Specifically, when battery cell 50 in accommodation space 25 normally works, can make closing cap piece 2211 seal up air inlet 221 reliably and stably, can prevent like this that vehicle 100 from when assembling production, the foreign matter blocks up air inlet 221, influence the unobstructed of air inlet 221, when battery cell 50 in accommodation space 25 takes place the thermal runaway, the high-pressure gas fire stream of high temperature will melt weakening structure portion in the twinkling of an eye, thereby realize switching on of air inlet 221, so set up, when not only can guaranteeing that battery cell 50 appears the thermal runaway, accommodation space 25 switches on with first exhaust passage 34, and the principle of switching on is relatively simple, can conveniently implement.

As shown in fig. 5, the air outlet 262 is provided with a balance valve 2621, and the balance valve 2621 can detect the pressure in the second exhaust channel 261 and selectively adjust the amount of air discharged from the air outlet 262 according to the detection result, for example: when the air pressure in the second exhaust passage 261 is high, the balance valve 2621 may control the air outlet 262 to increase the amount of the high-temperature and high-pressure spark stream discharged per unit time, so as to rapidly reduce the air pressure in the second exhaust passage 261, so that the structure of the accommodating space 25 is stable, and when the air pressure in the second exhaust passage 261 is small and is close to the external air pressure, the balance valve 2621 may control the air outlet 262 to decrease the amount of the high-temperature and high-pressure spark stream discharged per unit time until the air pressure in the second exhaust passage 2611 is equal to the external air pressure, the balance valve 2621 controls the air outlet 262 to stop discharging air, so as to further improve the stability and reliability of the discharging air of the second exhaust passage 261.
