In addition, the plurality of battery cells 50 are sequentially arranged and connected to each other, wherein the plurality of battery cells 50 may be arranged in a row and/or in a column, it should be noted that the plurality of battery cells 50 may be arranged in a row or in a front-back direction, and the plurality of battery cells 50 may be arranged in a column or in a left-right direction, so that not only the plurality of battery cells 50 may be arranged in the accommodating space 25 in compliance with the shape of the accommodating space 25, the integration level of the plurality of battery cells 50 on the vehicle 100 may be increased, the plurality of battery cells 50 may be more compact, and on the premise that the volume of the accommodating space 25 is constant, the accommodating space 25 may be provided with more battery cells 50, thereby further increasing the mileage of the vehicle 100 without changing the volume of the vehicle 100, and further stabilizing the plurality of battery cells 50, so that the reliability of the vehicle 100 can be further improved.

Among them, connecting the plurality of battery cells 50 to each other can make the plurality of battery cells 50 supply power to the vehicle 100 together, and can further improve the reliability of the plurality of battery cells 50. Also, the positions where the bottom plate 30 and the top plate 33 are required to be sealed with the chassis 20 are provided with corresponding sealing materials and sealing structures, so as to further improve the sealing performance of the accommodating space 25, further improve the safety of the plurality of battery cells 50 in the accommodating space 25, and prolong the service life of the plurality of battery cells 50.

In addition, the left rocker beam 21, the right rocker beam 22, the front cross beam 23 and the rear cross beam 24 are all insulated from the battery cell 50, so that when thermal runaway of the battery cell 50 occurs and high-temperature and high-pressure gas-fire current is generated, heat is prevented from being transferred outwards through the left rocker beam 21, the right rocker beam 22, the front cross beam 23 and the rear cross beam 24, users around the vehicle 100 are injured, or parts of the vehicle 100 adjacent to the left rocker beam 21, the right rocker beam 22, the front cross beam 23 and the rear cross beam 24 are damaged, and therefore the stability and the reliability of the vehicle 100 can be further improved.

Specifically, battery cell 50 in accommodation space 25 takes place the thermal runaway, when producing the high-temperature high-pressure gas fire stream, the high-temperature high-pressure gas fire stream can advance among the accommodation space 25 into exhaust duct 34, because exhaust duct 34 is linked together with the external world, can make the high-temperature high-pressure gas fire stream advance the exhaust to the external world from exhaust duct 34, so set up, not only can guarantee high-temperature high-pressure gas fire stream and arrange stability and the reliability to the external world from accommodation space 25, but also can make full use of left threshold roof beam 21 and right threshold roof beam 22 and exhaust, need not to set up other parts, thereby can simplify vehicle 100's structural design to a certain extent. 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. 8, the exhaust passage 34 vents air obliquely downward to vent the air flow obliquely downward after the thermal runaway of the battery cell 50. Specifically, by discharging the exhaust gas passage 34 obliquely downward, the stream of high-temperature, high-pressure gas fire can be discharged obliquely downward, which can improve the direction of discharge of the vehicle 100, preventing secondary damage to the vehicle occupant and foreign objects under parallel jet with the road surface.

As shown in fig. 2 to 5, at least one of the left and right rocker beams 21 and 22 is provided with an air inlet 221 and an air outlet 222, the exhaust passage 34 communicates between the air inlet 221 and the air outlet 222, the air inlet 221 is provided on an inner side wall of at least one of the left and right rocker beams 21 and 22, and the air outlet 222 is provided on an outer side wall. Specifically, since the left and right rocker beams 21 and 22 are portions defining the accommodating space 25, the air inlet 221 is opened directly in the inner side wall of at least one of the left and right rocker beams 21 and 22, and the air outlet 222 corresponding to the air inlet 221 is opened in the outer side wall of at least one of the left and right rocker beams 21 and 22, when the battery cell 50 is out of control and a high-temperature and high-pressure fire flow is generated, the high-temperature and high-pressure fire flow can be caused to enter the exhaust passage 34 directly through the air inlet 221 in the inner side wall of the left or right rocker beam 21 or 22 and to flow to the outside through the air outlet 222 in the outer side wall of the left or right rocker beam 21 or 22, which not only makes more sufficient use of the available space on the inner and outer side walls of the left or right rocker beam 21 or 22, but also makes it easier to make the path of the high-temperature and high-pressure fire flow from the accommodating space 25 to the outside, the exhaust efficiency of the exhaust passage 34 can be further improved.

Furthermore, the gas outlet 222 is obliquely arranged towards the obliquely lower side, so that the high-temperature and high-pressure gas fire flow can be directly discharged towards the obliquely lower side when being discharged from the gas outlet 222, a structure for guiding the gas fire flow towards the obliquely lower side is not required to be arranged in the exhaust passage 34, and the structural design of the exhaust passage 34 can be simplified on the premise that the high-temperature and high-pressure gas fire flow is ensured to be stably and continuously discharged towards the obliquely lower side.

As shown in fig. 8, at least one of the left and right rocker beams 21 and 22 is provided with an air inlet 221 and an air outlet 222, the air inlet 221 is provided on an inner side wall of at least one of the left and right rocker beams 21 and 22, and the air outlet 222 is provided on an outer side wall, a guide portion 35 that slants downward is provided in the exhaust passage 34, and the guide portion 35 is provided between the air inlet 221 and the air outlet 222. Specifically, when the battery cell 50 is thermally runaway and a high-temperature and high-pressure fire flow is generated, the high-temperature and high-pressure fire flow can be directly introduced into the exhaust passage 34 through the air inlet 221 on the inner side wall of the left or right threshold beam 21 or 22 and can flow to the outside through the air outlet 222 on the outer side wall of the left or right threshold beam 21 or 22, and the exhaust efficiency of the exhaust passage 34 can be further improved.

Further, by providing the obliquely downward guide portion 35 in the exhaust passage 34 and locating the guide portion 35 between the air inlet 221 and the air outlet 222, the high-temperature and high-pressure fire stream can be guided to the air outlet 222 through the obliquely downward guide portion 35 after entering the exhaust passage 34 from the air inlet 221, and can be discharged obliquely downward from the air outlet 222, which not only ensures that the high-temperature and high-pressure fire stream can be stably and reliably discharged obliquely downward, but also improves the stability and reliability of the flow of the high-temperature and high-pressure fire stream in the exhaust passage 34.

Further, 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 exhaust passage 34 in at least one of the left and right rocker beams 21 and 22 into a plurality of sub-exhaust passages 341, the guide portion 35 is located between the reinforcement portion 36 and the air outlet 222, and the flow of the ignition gas may pass through the sub-exhaust passages 341 and then be guided to the air outlet 222 by the guide portion 35, so that not only the structural strength of the left and right rocker beams 21 and 22 may be further improved, but also the direction of the exhaust gas may be changed.

As shown in fig. 8, the guide portion 35 includes: the upper guide plate portion 351 and the lower guide plate portion 352 are disposed between the air inlet 221 and the air outlet 222 and are disposed opposite to each other in the vertical direction, and the upper guide plate portion 351 and the lower guide plate portion 352 extend obliquely downward in the inward-outward direction, so that the guide portion 35 defined by the upper guide plate portion 351 and the lower guide plate portion 352 can be ensured to extend obliquely downward, and on the premise that the direction obliquely downward of the high-temperature and high-pressure flame flow is stably and reliably guided, not only the structure of the guide portion 35 can be simplified, and thus the structural design of the vehicle 100 can be simplified, but also the flow of the high-temperature and high-pressure flame flow in the guide portion 35 can be quickly and directly performed, and thus the exhaust efficiency of the exhaust passage 34 can be improved to some extent.

As shown in fig. 6, the plurality of battery cells 50 are arranged in a row in the accommodating space 25, a first gap 53 is left between two adjacent rows of the battery cells 50, a second gap 54 is left between at least one of the left threshold beam 21 and the right threshold beam 22 and the battery cell 50, and the second gap 54 is communicated with the first gap 53 and the air inlet 221. Specifically, it should be noted that, a plurality of battery cells 50 are arranged in a row and can be arranged for following the left and right direction, a plurality of battery cells 50 are arranged in a row and can be arranged for following the front and back direction, through leaving first clearance 53 between two battery cells 50, not only can promote the area of contact of the air in battery cell 50 and accommodation space 25, thereby can make things convenient for battery cell 50's heat transfer cooling, and when a battery cell 50 temperature rose, the heat will not transmit to the battery cell 50 of adjacent one, so can guarantee adjacent two battery cell 50's independence to a certain extent, thereby can promote a plurality of battery cell 50's reliability.

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, but also the contact area between the battery cell 50 and the air can be increased, and when the battery cell 50 is out of control thermally and generates a high-temperature high-pressure fire flow, the high-temperature high-pressure fire flow can enter the second gap 54 from the first gap 53 and then enter the exhaust passage 34 from the second gap 54 through the air inlet 221, so that the stability and smoothness of the high-temperature high-pressure fire flow entering the exhaust passage 34 can be further increased, and the exhaust efficiency can be increased to a certain extent.

As shown in fig. 1 and 2, the chassis 20 may further mainly include: and an inner partition beam 40, the inner partition beam 40 being disposed in the accommodating space 25 and dividing the accommodating space 25 into at least two sub-accommodating spaces 251. Specifically, the inner partition beam 40 is arranged to divide the accommodating space 25 into at least two sub-accommodating spaces 251, and after the plurality of battery cells 50 are divided into a plurality of parts having the same number, the same shape and the same volume as the sub-accommodating spaces 251, the plurality of parts correspond to the at least two sub-accommodating spaces 251 one-to-one and are installed and arranged in the at least two sub-accommodating spaces 251.

So set up, under the prerequisite that does not influence a plurality of battery monomer 50 reliable and stable setting on accommodation space 25, on the one hand can promote the area of a plurality of battery monomer 50 and external contact heat transfer, particularly, when there is not interior spacer beam 40 in accommodation space 25, a plurality of battery monomer 50 only with left threshold roof beam 21, right threshold roof beam 22, front beam 23, rear beam 24, roof 33 and bottom plate 30 carry out the heat transfer cooling of contacting, set up interior spacer beam 40 back in accommodation space 25, a plurality of battery monomer 50 not only can with left threshold roof beam 21, right threshold roof beam 22, front beam 23, rear beam 24, roof 33 and bottom plate 30 carry out the heat transfer cooling of stabilizing contact, can also carry out the heat transfer of contacting with interior spacer beam 40, thereby can reduce the temperature of a plurality of battery monomer 50 during operation to a certain extent, and then can promote a plurality of battery monomer 50's reliability.

On the other hand, the inner partition beam 40 may partition the accommodating space 25 into at least two sub-accommodating spaces 251, and when the temperature of one or more battery cells 50 in one sub-accommodating space 251 is sharply increased, even if a fire occurs, the inner partition beam 40 may partition the battery cells 50 in the sub-accommodating space 251 from the battery cells 50 in the other sub-accommodating spaces 251, and may prevent the high temperature or fire from spreading from the sub-accommodating spaces 251 to the other sub-accommodating spaces 251, so that the reliability of the plurality of battery cells 50 and the vehicle 100 may be further improved.

In addition, the inner partition beam 40 may also play a role in enhancing the structural strength of the chassis 20 to a certain extent, so that the stability and the firmness of the accommodating space 25 may be enhanced, and further, the reliability of the installation and the arrangement of the plurality of battery cells 50 in the accommodating space 25 may be enhanced.

As shown in fig. 8, the left and right threshold beams 21 and 22 are provided with the lap joint 37, and after the inner partition beam 40 is lapped on the lap joint 37 of the left and right threshold beams 21 and 22, the lap joint can 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 37 is provided with the glue groove 38, and the glue groove 38 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.

In some embodiments, the inner partition beams 40 are at least two, and are the cross partition beams 41, two ends of the at least two cross partition beams 41 are respectively connected to the left threshold beam 21 and the right threshold beam 22, and are spaced in the front-rear direction, so that the accommodating space 25 can be partitioned into a plurality of sub accommodating spaces 251 arranged in the front-rear direction, and thus the plurality of battery cells 50 can be partitioned into at least three parts in the front-rear direction, which not only can further increase the contact heat exchange area of the plurality of battery cells 50 with the inner partition beams 40 and improve the heat exchange performance of the plurality of battery cells 50, but also 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 partitioned into at least three parts, the inner partition beams 40 can partition the sub accommodating space of the battery cell 50 in which 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, 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. 6, 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 air and fire flow can rapidly and directly enter the second gap 54 through the third gap 55 and then directly enter the 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 one air outlet 222. 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 34 through the air inlets 221 be ensured, but also the air intake efficiency can be improved.

Further, the second gap 54 of each sub-accommodation space 251 corresponds to one air outlet 222, so that a certain pressure can be ensured when the high-temperature and high-pressure fire stream in the exhaust channel 34 is exhausted from the air outlet 222, and the high-temperature and high-pressure fire stream can be sprayed out from the air outlet 222 at a certain speed, so that the air outlet efficiency can be improved, the high-temperature and high-pressure fire stream can be prevented from flowing back to the exhaust channel 34, and the stability and reliability of exhaust can be improved.

As shown in fig. 2 to 5, the air outlet area of the air outlet 222 is larger than the air inlet area of the air inlet 221. Specifically, since each sub-accommodation space 251 corresponds to a plurality of air inlets 221 and corresponds to one air outlet 222, if the air inlet area of a single air inlet 221 is set to be equal to the air outlet area of the air outlet 222, the amount of the high-temperature and high-pressure air-fuel flow entering the exhaust channel 34 is greater than the outflow amount in a unit time, which may cause uneven air inlet and exhaust, resulting in that the exhaust channel 34 may be charged with accumulated high-temperature and high-pressure air-fuel flow for a long time, and the high-temperature and high-pressure air-fuel flow in the second gap 54 may not smoothly enter the exhaust channel 34, and therefore, the air outlet area of the air outlet 222 is set to be greater than the air inlet area of the air inlet 221, which may improve the smoothness of air inlet and outlet of the exhaust channel 34, and may improve the reliability of the exhaust channel 34.

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 the battery cell 50 in the accommodating space 25 normally works, the sealing cover 2211 can be used for stably and reliably sealing the air inlet 221, so that the vehicle 100 can be prevented from being assembled and produced, the foreign matter blocks the air inlet 221, smoothness of the air inlet 221 is affected, when the battery cell 50 in the accommodating space 25 is in thermal runaway, high-temperature and high-pressure gas fire flow can be instantly melted to weaken the structural part, and accordingly the conduction of the air inlet 221 is realized, so that the arrangement is realized, when the thermal runaway of the battery cell 50 can be ensured, the conduction of the accommodating space 25 and the exhaust channel 34 is realized, the conduction principle is relatively simple, and the implementation is convenient. The breakable weakening structure portion may be a plug, a film, and a mesh enclosure, including but not limited to these, which are not described herein again.

As shown in fig. 2, 4 and 8, the air outlet 222 is provided with an explosion-proof valve 2221, and the explosion-proof valve 2221 can detect the pressure in the exhaust passage 34 and selectively adjust the amount of exhaust from the air outlet 222 according to the detection result, for example: when the air pressure in the exhaust passage 34 is high, the explosion-proof valve 2221 may control the air outlet 222 to increase the amount of the high-temperature and high-pressure fire flow discharged per unit time, so that the air pressure in the exhaust passage 34 may be rapidly reduced, and the structure of the exhaust passage 34 and the accommodating space 25 may be kept stable, and when the air pressure in the exhaust passage 34 is small and is close to the external air pressure, the explosion-proof valve 2221 may control the air outlet 222 to decrease the amount of the high-temperature and high-pressure fire flow discharged per unit time until the air pressure in the exhaust passage 34 is equal to the external air pressure, and the explosion-proof valve 2221 controls the air outlet 222 to stop exhausting, so that the stability and reliability of the exhaust passage 34 may be further improved.

Further, the explosion-proof valve 2221 is provided with a waterproof breathable membrane, so that the explosion-proof valve 2221 can continuously and reliably measure the air pressure in the exhaust passage 34 through the waterproof breathable membrane on the premise that the explosion-proof valve 2221 is corroded and damaged by preventing water from contacting with the explosion-proof valve 2221, the normal operation of the explosion-proof valve 2221 can be prevented from being affected by the waterproof breathable membrane, and thus the stability and reliability of the explosion-proof valve 2221 can be further improved.

Further, a high temperature resistant, fire resistant and flame retardant material is disposed on a side of the top plate 33 facing the accommodating space 25, so that when the battery cell 50 is in fire, high temperature gas or flame can be prevented from burning through the top plate 33 and entering the driving cab 11, which endangers the life safety of the driver and passengers in the driving cab 11, and thus the reliability of the top plate 33 and the whole vehicle 100 can be further improved.

In addition, the reinforcing rib 331 is arranged on the top plate 33, and the reinforcing rib 331 is correspondingly connected with the inner partition beam 40 inside the accommodating space 25, so that mutual independence of each sub-accommodating space 251 can be further ensured, a physical isolation effect can be achieved, and after thermal runaway of the battery cell 50 can be further prevented, high-temperature and high-pressure gas fire flows enable the top plate 33 to expand and deform, and the high-temperature and high-pressure gas fire flows are serially connected in the accommodating space 25, so that thermal runaway of the battery cell 50 is diffused and spread in advance, and thus the reliability of the vehicle 100 can be further improved.
