Further, as shown in fig. 1-2, the area defined by the left rocker beam 21, the right rocker beam 22, the front cross beam 23 and the rear cross beam 24 is the accommodating space 25, the bottom plate 30 is disposed at the bottom of the chassis 20 and closes the bottom of the accommodating space 25, the top plate 33 is disposed at the top of the chassis 20 and is disposed opposite to the bottom plate 30, the top plate 33 closes the top of the accommodating space 25, the plurality of battery cells 50 are sequentially arranged and connected, and the plurality of battery cells 50 are disposed in the accommodating space 25. Specifically, the top plate 33 and the bottom plate 30 are respectively provided at the top and bottom of the accommodating space 25, and the top and bottom of the accommodating space 25 are respectively sealed, so that the airtightness of the accommodating space 25 can be ensured.

On the other hand, left threshold roof beam 21, right threshold roof beam 22, front beam 23 and rear frame member 24 interconnect, and the leakproofness of junction is all better, set up roof 33 and bottom plate 30 respectively behind accommodation space 25's top and bottom, can also make roof 33 and bottom plate 30 carry out reliable and stable reliably with accommodation space 25's top and bottom respectively sealed, can make accommodation space 25 whole separate with the external world like this, set up a plurality of battery monomer 50 back in accommodation space 25, can make a plurality of battery monomer 50 separate with the external world, can prevent the erosion of external foreign matter and the impact of external force from damaging a plurality of battery monomer 50, thereby can promote a plurality of battery monomer 50's stability and life, and then can promote vehicle 100's reliability.

Further, the top plate 33 and the bottom plate 30 are original structures of the vehicle 100, that is, even if the plurality of battery cells 50 are not provided in the vehicle 100, the top plate 33 and the bottom plate 30 are provided in the vehicle 100, the bottom plate 30 can separate the vehicle 100 from a road surface at the bottom of the vehicle 100, prevent foreign objects on the road surface from damaging parts of the vehicle 100, and the top plate 33 can be provided for installation of other components of the vehicle 100 and for seating of a driver and passengers.

Thus, the left rocker beam 21, the right rocker beam 22, the front cross beam 23, the rear cross beam 24, the roof panel 33, and the floor panel 30 that define and seal the accommodation space 25 are all original structures on the vehicle 100, that is, the left rocker beam 21, the right rocker beam 22, the front cross beam 23, the rear cross beam 24, the roof panel 33, and the floor panel 30 are not structures that are provided individually for the vehicle 100 to install and set a plurality of battery cells 50, but define and seal the accommodation space 25 together while the left rocker beam 21, the right rocker beam 22, the front cross beam 23, the rear cross beam 24, the roof panel 33, and the floor panel 30 do not lose their respective functions on the vehicle 100, so as to install and set a plurality of battery cells 50 stably and reliably.

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.

Further, as shown in fig. 1 to 6, both ends of the partitioning beam 41 are connected to the left and right rocker beams 21 and 22, respectively, and partition the accommodating space 25 into at least two sub-accommodating spaces 251, the partitioning beam 41 is provided with a first exhaust passage 412, at least one of the left and right rocker beams 21 and 22 is provided with a second exhaust passage 223, the first exhaust passage 412 is communicated with the sub-accommodating spaces 251, and the second exhaust passage 223 is communicated with the first exhaust passage 412 and with the external environment to exhaust the ignition flow after the thermal runaway of the battery cell 50. Specifically, both ends of the partitioning beam 41 are connected to the left and right rocker beams 21 and 22, respectively, and partition the accommodating space 25 into a plurality of sub-accommodating spaces 251 that are provided at intervals in the front-rear direction. Therefore, the plurality of battery cells 50 can be separated into at least four parts, so that not only can the area of the plurality of battery cells 50 contacting with air for heat exchange be further increased, and the heat exchange performance of the plurality of battery cells 50 be improved, but also when the battery cells 50 in a certain sub-accommodation space 251 are in high-temperature fire, because the plurality of battery cells 50 are separated into at least four parts, the inner partition beam 40 can separate the sub-accommodation space 251 of the battery cell 50 in which the high-temperature fire occurs from the battery cells 50 in other sub-accommodation spaces 251, and the loss can be reduced.

In addition, since the longitudinal beams 42 and the transverse beams 41 divide the accommodating space 25 into a 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, when the battery cell 50 in the accommodating space 25 is out of control due to thermal runaway and generates a high-temperature high-pressure fire stream, the high-temperature high-pressure fire stream in the accommodating space 25 can firstly flow into the first exhaust channel 412 on the cross beam 41, and since the second exhaust channel 223 on at least one of the left and right threshold beams 21 and 22 is communicated with the first exhaust channel 412, the high-temperature high-pressure fire stream can firstly flow into the second exhaust channel 223 from the first exhaust channel 412, and since the second exhaust channel 223 is communicated with the external environment, the high-temperature high-pressure fire stream can flow into the external environment from the second exhaust channel 223, so that the arrangement not only can ensure the stability and reliability of the high-temperature high-pressure fire stream exhausted from the accommodating space 25 to the external environment, but also can fully utilize at least one of the left and right threshold beams 21 and 22 and the cross beam 41 to exhaust, no additional components need to be provided, so that the structural design of the vehicle 100 can be simplified to some 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.

Therefore, when thermal runaway of the battery cell 50 occurs, exhaust can be performed through at least one of the left rocker beam 21 and the right rocker beam 22 and the cross member 41, exhaust can be performed by making full use of the original structure of the vehicle 100, and the structure of the vehicle 100 can be simplified.

As shown in fig. 1-2, the plurality of battery cells 50 are arranged in rows and columns in the accommodating space 25, a first gap 53 is left between two adjacent rows of battery cells 50, a second gap 54 is left between the battery cells 50 and the transverse beam 41, the first gap 53 is communicated with the second gap 54, and the second gap 54 is communicated with the first air inlet 411. 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, the second gap 54 is reserved between the diaphragm 41 and the battery cell 50, and the first gap 53 is communicated with the second gap 54, so that not only can the contact area between the battery cell 50 and the air be further increased, the contact area between the battery cell 50 and the air be increased, but also when the battery cell 50 is out of control thermally 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 412 from the second gap 54 through the first air inlet 411, so that the stability and smoothness of the high-temperature and high-pressure fire flows entering the first exhaust channel 412 can be further increased, and the exhaust efficiency can be improved to a certain extent.

As shown in fig. 10, the chassis 20 may further mainly include: the longitudinal partition beam 42 and the transverse partition beam 41 are arranged in a crossed mode, the longitudinal partition beam 42 and the transverse partition beam 41 are jointly divided into a plurality of sub-containing spaces 251, a third gap is reserved between the longitudinal partition beam 42 and the battery cell 50 in each sub-containing space 251, a fourth gap 55 is reserved between one of the left doorsill beam 21 and the right doorsill beam 22 and the battery cell 50, and the third gap and the fourth gap 55 are communicated with the second gap 54. Specifically, the third gap and the fourth gap 55 are provided to increase the contact area between the battery cell 50 and the air, so as to increase the heat dissipation performance of the battery cell 50, and to enable the high-temperature and high-pressure fire flow to flow from the third gap and the fourth gap 55 to the second gap 54 and to flow to the first air inlet 411 through the second gap 54 when the battery cell 50 generates heat effect and generates high-temperature and high-pressure fire flow, so as to further increase the exhaust efficiency of the vehicle 100.

As shown in fig. 1 to 6, the first air inlet 411 is plural, and the plural first air inlets 411 are arranged at intervals in the left-right direction. Specifically, the plurality of first air inlets 411 are arranged at intervals in the left-right direction, so that not only can the amount of air entering the first exhaust passage 412 per unit time be increased, but also the flow of high-temperature and high-pressure air in the accommodating space 25 can be made more uniform when entering the first exhaust passage 412 through the first air inlets 411, and thus the reliability of exhaust of the vehicle 100 can be further improved.

As shown in fig. 7 and 8, a reinforcing plate 413 is provided in the beam 41, the reinforcing plate 413 extends left and right and divides the first exhaust passage 412 into a plurality of sub-exhaust passages 4121, and each of the plurality of sub-exhaust passages 4121 communicates with the sub-receiving space 251. Specifically, the reinforcing plate 413 extends left and right in the partition beam 41 to divide the first exhaust passage 412 into a plurality of sub-exhaust passages 4121, and after the high-temperature and high-pressure fire air flows into the first exhaust passage 412 in the sub-receiving space 251 on one of the two sides of the partition beam 41, the two sides of the partition beam 41 can be divided, so that the high-temperature and high-pressure fire air flows into the sub-receiving space 251 on the other of the two sides of the partition beam 41 through the first air inlet 411, and the battery cells 50 on the other side of the partition beam 41, which are not in thermal runaway, can be prevented from being damaged, and thus the reliability of the receiving space 25 can be further improved. In addition, the reinforcing plate 413 can also improve the structural strength of the diaphragm 41, and thus can further improve the structural reliability of the vehicle 100.

As shown in fig. 1 to 2, at least one of the left and right rocker beams 21 and 22 is provided with an air outlet 222, the air outlet 222 is communicated with the second exhaust passage 223, and the air outlet 222 is provided on an outer side wall and/or a bottom wall of at least one of the left and right rocker beams 21 and 22. Specifically, by providing the air outlet 222 on the outer side wall and/or the bottom wall of at least one of the left rocker beam 21 and the right rocker beam 22, it is possible to prevent the high-temperature and high-pressure fire and air flowing out of the air outlet 222 from affecting the driver or passenger on the vehicle 100 and the surroundings of the vehicle 100 on the premise of ensuring smooth and stable air outlet of the air outlet 222, which may further improve the reliability of the vehicle 100.

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.

Specifically, set up heat conduction pad 51 with a plurality of battery monomer 50's bottom, can be when cooling liquid heat transfer cooling in a plurality of battery monomer 50 and liquid cooling runner 311, make heat transfer between them more even, specifically speaking, a plurality of battery monomer 50 can be with heat line transmission to heat conduction pad 51 on, the heat can be earlier dispersed evenly on heat conduction pad 51, the transmission, back on heat evenly distributed to heat conduction pad 51, carry out the heat transfer with the coolant liquid in the liquid cooling runner 311 again, with heat transmission to the coolant liquid in, can make a plurality of battery monomer 50's heat dissipation more even quick like this, can promote a plurality of battery monomer 50's heat exchange efficiency.

Further, the heat conducting pad 51 may be made of a heat conducting adhesive, and is configured as such, on the one hand, on the premise that the heat conducting adhesive does not scratch and abrade the lower surfaces of the plurality of battery cells 50, the force applied to the bottoms of the plurality of battery cells 50 plays a role in buffering and blocking, and the bottom of the vehicle 100 can be further prevented from being damaged by external force impact, so that the reliability of the plurality of battery cells 50 can be improved, on the other hand, the plurality of battery cells 50 can be stably and firmly arranged on the heat conducting pad 51, so that the heat conducting pad 51 is arranged in the accommodating space 25, and thus the plurality of battery cells 50 are stably and firmly arranged in the accommodating space 25, so that the overall mode of the plurality of battery cells 50 can be effectively improved, and the force applied to or the connection failure of a single battery cell 50 can be avoided.

Further, one of the top plate 33 and the bottom plate 30 is fixed to the chassis 20, and the other is detachably provided to the chassis 20. Specifically, when a plurality of battery cells 50 normally work, the accommodation space 25 handles the sealed state, when a plurality of battery cells 50 break down, need maintenance or change, the accommodation space 25 needs to be opened, therefore, one of the top plate 33 and the bottom plate 30 is fixed on the chassis 20, the other is detachably arranged on the chassis 20, when a plurality of battery cells 50 break down, need maintenance or change, only one of the top plate 33 and the bottom plate 30 detachably connected with the chassis 20 needs to be detached, so that a plurality of battery cells 50 in the accommodation space 25 can be maintained or changed, and thus, the later maintenance of the vehicle 100 by a user can be facilitated.

It should be noted that, when the bottom plate 30 is detachably installed on the chassis 20, and the bottom plate 30 is detached to repair and replace the plurality of battery cells 50 in the accommodating space 25, it is necessary to operate from bottom to top to repair and replace the plurality of battery cells 50, and when the top plate 33 is detached to repair and replace the plurality of battery cells 50 in the accommodating space 25, it is necessary to operate from top to bottom to repair and replace the plurality of battery cells 50.

Therefore, through having the liquid cooling board 31 on making the bottom plate 30, connect liquid cooling joint 312 on the liquid cooling runner 311 in making the liquid cooling board 31, the coolant liquid can get into the liquid cooling runner 311 among the liquid cooling board 31 through liquid cooling joint 312, when the coolant liquid carries out stable continuous flow in liquid cooling runner 311, can carry out even heat transfer steadily with a plurality of battery monomer 50, thereby can reduce a plurality of battery monomer 50's temperature, so not only can further promote a plurality of battery monomer 50's heat dispersion, and liquid cooling board 31 still can not occupy accommodation space 25, thereby can not exert an influence to a plurality of battery monomer 50's installation setting. The cooling liquid may be water, but is not limited thereto.

It should be noted that the coolant flows out from the cooling system of the vehicle 100, exchanges heat with the plurality of battery cells 50, and flows back to the cooling system of the vehicle 100 again to be cooled after the temperature of the coolant itself rises, and continues to flow into the liquid cooling flow passage 311 to stably cool the plurality of battery cells 50 after the temperature of the coolant returns to a normal value again, so as to implement a cooling cycle for the plurality of battery cells 50, thereby further improving the reliability of the liquid cooling plate 31.

Further, set up backplate 32 in the bottom of liquid cooling board 31, can make backplate 32 play the effect of sheltering from the protection to liquid cooling board 31, can prevent like this that external force from assaulting liquid cooling board 31, lead to liquid cooling board 31 to take place to damage, cause liquid cooling board 31 can't form heat transfer cooling effectively to a plurality of battery monomer 50, can further promote bottom plate 30's reliability like this. The protective plate 32 may be made of high-strength steel, and an armor layer is sprayed on the surface of the protective plate 32, so that the structural strength of the protective plate 32 can be further improved, the protection performance of the protective plate 32 on the liquid cooling plate 31 can be improved, and the reliability of the plurality of battery cells 50 in the accommodating space 25 can be further improved.
