[0058] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0059] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0060] A vehicle body assembly 1000 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0061] Combination Figure 1 , Figure 2 and Figure 3 As shown, a vehicle body assembly 1000 according to an embodiment of the present invention includes: a vehicle frame 100 , an isolation member 200 , and at least two battery cell groups 310 .

[0062] Among them, combined Figure 1 , Figure 2 and Figure 3 As shown, the frame 100 includes at least two support beams 120, and the at least two support beams 120 are arranged in a first direction. It should be noted that the first direction mentioned here can be understood as Figure 1 and Figure 2 The X direction shown in the figure can also be understood as the direction between the driver's seat and the co-driver's seat of the vehicle, that is, at least two support beams 120 are arranged at intervals along the X direction of the vehicle.

[0063] Combination Figure 1 , Figure 2 and Figure 3 As shown, the isolation member 200 is disposed between two adjacent support beams 120, and the isolation member 200 cooperates with the two adjacent support beams 120 on opposite sides of the second direction to form a receiving space, and the second direction intersects the first direction. The second direction mentioned here can be understood as Figure 3The Z direction shown in can also be understood as the direction between the bottom and the roof of the vehicle. Here, it means that when the isolation member 200 is arranged between two adjacent support beams 120, the isolation member 200 can cooperate with the two adjacent support beams 120 on both opposite sides in the second direction to form a receiving space, thereby reducing the difficulty of forming the receiving space and thus reducing the difficulty of fixing the battery cell group 310.

[0064] Combination Figure 1 , Figure 2 and Figure 3 As shown, at least two battery cell groups 310 are respectively disposed on opposite sides of the isolation member 200 in the second direction, so that the battery cell groups 310 are disposed in the accommodation space.

[0065] It should be noted that the at least two groups of battery cell groups 310 mentioned here can be understood as two groups, three groups, four groups or more groups. By providing at least two groups of battery cell groups 310, it is helpful to increase the capacity of the battery cell groups 310. In this way, when the body assembly 1000 is provided in the vehicle, it is helpful to improve the vehicle's cruising range and thus improve the driving experience.

[0066] At the same time, by arranging the isolation member 200 between two adjacent support beams 120, the isolation member 200 and the two adjacent support beams 120 can support each other, so that the overall rigidity of the combination of the isolation member 200 and the two adjacent support beams 120 is relatively high. In this way, when the battery cell group 310 is arranged in the accommodating space, the influence of the torsional deformation of the support beam 120 on the battery cell group 310 can be effectively reduced, thereby extending the service life of the battery cell group 310.

[0067] In addition, when the battery cell group 310 is arranged in the accommodating space, on the one hand, the isolation piece 200 can be used in conjunction with two adjacent support beams 120 to form the outer shell of the battery cell group 310, which is convenient for eliminating the setting of the traditional battery pack outer shell. On the other hand, the setting of the fixing ears can also be eliminated, thereby improving the integration of the battery cell group 310 and the body assembly 1000, and further improving the integration of the battery cell group 310 and the vehicle. It can not only simplify the structure of the vehicle, but also allow sufficient space in the vehicle to arrange the battery cell group 310, which is beneficial to increase the effective volume of the battery cell group 310 and improve the energy density of the battery cell group 310.

[0068] It is also worth noting that the present application arranges at least two groups of battery cell groups 310 on opposite sides of the isolation member 200 in the second direction, so that one isolation member 200 can be used to support and protect the two groups of battery cell groups 310 at the same time, thereby improving the positional stability of the battery cell groups 310 and extending the service life of the battery cell groups 310. The isolation member 200 can also be used to achieve isolation and coordination of the two groups of battery cell groups 310, thereby avoiding short circuits of adjacent battery cell groups 310 to a certain extent, thereby improving the safety of the battery cell groups 310.

[0069] In summary, at least two battery cell groups 310 of the present application can be directly fixed by the support beam 120 and the isolation member 200 of the frame 100, eliminating the setting of the outer shell and the lifting ears of the traditional battery pack, which is beneficial to increase the effective volume of the battery cell group 310 and improve the energy density of the battery cell group 310.

[0070] It can be seen from the above structure that the body assembly 1000 of the embodiment of the present invention, by setting an isolation member 200 between two adjacent support beams 120, and utilizing the isolation member 200 to cooperate with the two adjacent support beams 120 to form a accommodating space, when the battery cell group 310 is arranged in the accommodating space, the isolation member 200 can be utilized to cooperate with the two adjacent support beams 120 to form the outer shell of the battery cell group 310, and the isolation member 200 can be utilized to cooperate with the two adjacent support beams 120 to fix the battery cell group 310, so as to eliminate the setting of the traditional battery pack outer shell and the fixing ears, which can not only simplify the structure of the vehicle, but also allow sufficient space in the vehicle to arrange the battery cell group 310, which is beneficial to increase the effective volume of the battery cell group 310 and improve the energy density of the battery cell group 310.

[0071] At the same time, by arranging at least two groups of battery cell groups 310 on opposite sides of the isolation member 200 in the second direction, the isolation member 200 and the two adjacent support beams 120 can cooperate to simultaneously serve as the outer shell of at least two groups of battery cell groups 310, further simplifying the structure of the vehicle.

[0072] It can be understood that compared with the prior art of setting a shell on the periphery of the battery cell group 310 and setting the shell to be fixed to the vehicle body through the ear, the present application directly uses the isolation piece 200 and the two adjacent support beams 120 to form the shell of at least two groups of battery cell groups 310, which can not only save the setting of the traditional battery pack shell, but also save the setting of the fixing ear, simplify the structure of the vehicle, and make the vehicle have enough space to arrange the battery cell group 310, which is conducive to increasing the effective volume of the battery cell group 310, improving the energy density of the battery cell group 310, and ensuring the working performance of the battery cell group 310 to a certain extent.

[0073] In some embodiments, in the second direction, the isolation member 200 is disposed near the middle of the support beam 120, so that the isolation member 200 on opposite sides in the second direction can respectively cooperate with two adjacent support beams 120 to form a receiving space, so that at least two groups of battery cells 310 can be respectively arranged in the receiving space, which not only facilitates improving the vehicle's cruising range, but also enables the isolation member 200 to cooperate with the two adjacent support beams 120 to simultaneously serve as the outer shell of at least two groups of battery cells 310, thereby simplifying the structure of the vehicle.

[0074] In some embodiments, the two opposite ends of the spacer 200 in the first direction are respectively fixedly connected to the support beam 120. Here, when the spacer 200 is disposed between two adjacent support beams 120, the two opposite ends of the spacer 200 in the first direction are respectively fixedly connected to the support beam 120 to achieve a fixed connection between the spacer 200 and the support beam 120, so that the relative position of the spacer 200 and the support beam 120 is stable, thereby facilitating the formation of a structurally stable accommodation space, and facilitating the arrangement of the battery cell group 310 in the accommodation space.

[0075] At the same time, the above-mentioned arrangement can also enable the isolation member 200 and the two adjacent support beams 120 to support each other, thereby improving the overall rigidity of the isolation member 200 and the two adjacent support beams 120, avoiding the influence of the torsional deformation of the support beams 120 on the battery cell group 310 to a certain extent, and extending the service life of the battery cell group 310.

[0076] It should be noted that the fixed connection mentioned here can be welding, bonding or bolt connection, etc.

[0077] In some embodiments, in combination Figure 2 , Figure 3 and Figure 4 As shown, the isolation member 200 includes a support plate 210 and a connecting plate 220. The connecting plate 220 is provided on at least one side of the support plate 210 in the first direction. The connecting plate 220 and the support plate 210 extend in different directions. The connecting plate 220 is fixedly connected to the support beam 120. This realizes the fixed connection between the isolation member 200 and the support beam 120, and reduces the difficulty of the fixed connection between the isolation member 200 and the support beam 120.

[0078] At the same time, since the connecting plate 220 and the support plate 210 extend in different directions, the connecting plate 220 can be used to realize a fixed connection between the isolation member 200 and the support beam 120, thereby increasing the connection area between the isolation member 200 and the support beam 120, improving the connection strength between the isolation member 200 and the support beam 120, and further stabilizing the relative position of the isolation member 200 and the support beam 120, thereby improving the overall rigidity of the isolation member 200 and the two adjacent support beams 120.

[0079] The fixed connection between the connecting plate 220 and the supporting beam 120 may be welding, bonding or bolt connection.

[0080] In some embodiments, the connection plate 220 is welded or bolted to the support beam 120 , which is beneficial to increase the connection strength between the connection plate 220 and the support beam 120 , thereby increasing the connection strength between the isolation member 200 and the support beam 120 .

[0081] In some embodiments, in combination Figure 3 and Figure 4 As shown, the connecting plate 220 extends along the second direction and the third direction. The third direction mentioned here can be understood as Figure 3 The Y direction shown in the figure can also be understood as the direction between the front and rear of the vehicle. By setting the connecting plate 220 to extend along the second direction and the third direction, it is beneficial to increase the area of ​​the connecting plate 220. In this way, when the connecting plate 220 is used to realize the fixed connection between the isolation member 200 and the support beam 120, the connection area between the isolation member 200 and the support beam 120 can be increased, and the connection strength between the isolation member 200 and the support beam 120 can be improved.

[0082] Of course, in some other embodiments, the connecting plate 220 may not be provided, and the support plate 210 may be directly fixedly connected to the support beam 120. This can also achieve a fixed connection between the isolation member 200 and the support beam 120, simplify the structure of the isolation member 200, and reduce the difficulty of molding the isolation member 200.

[0083] In the description of the present invention, features defined as “first”, “second”, and “third” may explicitly or implicitly include one or more such features, and are used to distinguish and describe the features, without any distinction of order or importance.

[0084] In some embodiments, Figure 4 As shown, the connecting plates 220 include two, and the two connecting plates 220 are respectively arranged on two opposite sides of the support plate 210 in the first direction. In other words, the connecting plates 220 are arranged on two opposite sides of the support plate 210 in the first direction, so that the support plate 210 and two adjacent support beams 120 can be fixedly connected through the connecting plates 220, effectively increasing the connection area between the isolation member 200 and the support beam 120, and improving the connection strength between the isolation member 200 and the support beam 120.

[0085] In a specific example, combined with Figure 2 , Figure 3 and Figure 4As shown, the isolation member 200 includes a support plate 210 and two connecting plates 220. The two connecting plates 220 are respectively arranged on opposite sides of the support plate 210 in the first direction, so that the isolation member 200 forms an "H"-shaped structure. After the isolation member 200 is combined with the support beam 120, this structure can increase the fixing area of ​​the isolation member 200 and the support beam 120, thereby effectively increasing the overall rigidity of the combination of the isolation member 200 and the support beam 120.

[0086] In some embodiments, the support plate 210 and the connecting plate 220 are formed in one piece, so that the support plate 210 and the connecting plate 220 are formed as an integral piece, which not only reduces the difficulty of molding the isolation member 200, but also increases the connection strength between the support plate 210 and the connecting plate 220, so that the relative position of the support plate 210 and the connecting plate 220 is stable, so that the isolation member 200 can be effectively fixedly connected to the support beam 120 by using the connecting plate 220.

[0087] Of course, in some other embodiments, the support plate 210 and the connecting plate 220 may also be formed as separate parts. After the support plate 210 and the connecting plate 220 are formed separately, the support plate 210 and the connecting plate 220 are connected (such as welding, bonding or bolting, etc.), which can also form a structurally stable isolation member 200.

[0088] In some embodiments, in combination Figure 2 , Figure 3 and Figure 4 As shown, the connecting plate 220 is connected to the side of the support beam 120 away from the support plate 210. In this way, while achieving a fixed connection between the connecting plate 220 and the support beam 120, it can also avoid the connecting plate 220 occupying the space between two adjacent support beams 120 to a certain extent, so that there is a larger space between the two adjacent support beams 120 to arrange the battery cell group 310, which is conducive to further increasing the effective volume of the battery cell group 310 and improving the energy density of the battery cell group 310.

[0089] At the same time, by connecting the connecting plate 220 to the side of the support beam 120 away from the support plate 210, the difficulty of connecting the connecting plate 220 and the support beam 120 can be reduced, and the connection strength between the connecting plate 220 and the support beam 120 can be improved.

[0090] In a specific example, the connecting plate 220 can be firstly arranged on the side of the support beam 120 away from the pallet 210, and then the connecting plate 220 and the support beam 120 are connected, so that the connection point between the connecting plate 220 and the support beam 120 is arranged away from the pallet 210, thereby avoiding to a certain extent the pallet 210 from hindering the connection between the connecting plate 220 and the support beam 120, thereby reducing the difficulty of connecting the connecting plate 220 and the support beam 120.

[0091] Of course, in some other embodiments, the connecting plate 220 may also be connected to the side of the supporting beam 120 facing the supporting plate 210 .

[0092] In some embodiments, in combination Figure 4 , Figure 5 and Figure 6 As shown, the support beam 120 is provided with an assembly opening 124 facing the support plate 210, and the end of the support plate 210 connected with the connecting plate 220 is inserted into the assembly opening 124, so that the connecting plate 220 is arranged on the side of the support beam 120 away from the support plate 210. Thus, the connecting plate 220 can be connected to the side of the support beam 120 away from the support plate 210, reducing the difficulty of the connection between the connecting plate 220 and the support beam 120.

[0093] In some embodiments, in combination Figure 5 , Figure 6 and Figure 7 As shown, the support beam 120 includes a first support beam 121 and a second support beam 122 arranged opposite to each other in the second direction, and the first support beam 121 and the second support beam 122 are both provided with mounting openings 125 opening toward each other, and the two mounting openings 125 are arranged opposite to each other, and the two mounting openings 125 cooperate to form an assembly opening 124, and the second direction intersects with the first direction, thereby reducing the difficulty of forming the assembly opening 124.

[0094] At the same time, by configuring the support beam 120 to include a first support beam 121 and a second support beam 122 that are relatively arranged in the second direction, the difficulty of assembling the support plate 210 and the support beam 120 can be reduced, so that the end of the support plate 210 connected to the connecting plate 220 can be effectively passed through the assembly opening 124, and the connecting plate 220 can be effectively connected to the side of the support beam 120 that is away from the support plate 210.

[0095] Through the above-mentioned arrangement, during the specific assembly process of the support beam 120 and the isolation member 200, the isolation member 200 can be firstly arranged on the first support beam 121 or the second support beam 122, and the connecting plate 220 can be arranged on the side of the first support beam 121 or the second support beam 122 away from the support plate 210, and then the first support beam 121 and the second support beam 122 are assembled and connected, so that the end of the support plate 210 connected to the connecting plate 220 can be effectively passed through the assembly port 124, thereby reducing the difficulty of assembling the support beam 120 and the isolation member 200.

[0096] The first support beam 121 and the second support beam 122 may be connected by welding, bonding, etc., again without any specific limitation.

[0097] Of course, in some other embodiments, the support beam 120 is not limited to being configured to include a first support beam 121 and a second support beam 122. An assembly opening 124 that passes through the support beam 120 can also be directly opened, and the support plate 210 and the connecting plate 220 can be configured to be formed into separate parts. In the specific assembly process of the support beam 120 and the isolation member 200, the end of the support plate 210 in the first direction is first passed through the assembly opening 124, and then the support plate 210 and the connecting plate 220 are connected to form the isolation member 200, and finally the connecting plate 220 and the support beam 120 are connected. In this way, the end of the support plate 210 connected to the connecting plate 220 can be effectively passed through the assembly opening 124, so that the support beam 120 and the isolation member 200 are matched and connected, and the difficulty of assembling and connecting the support beam 120 and the isolation member 200 is reduced.

[0098] In some embodiments, in combination Figure 2 , Figure 3 and Figure 4 As shown, the spacer 200 further includes a limiting plate 230, and the limiting plate 230 is provided on at least one side of the support plate 210 in the third direction. The limiting plate 230, the support plate 210 and the support beam 120 cooperate to form a receiving space, and the third direction intersects with the first direction and the second direction. In this way, when the battery cell group 310 is arranged in the receiving space, the limiting plate 230 can be used to limit the battery cell group 310, thereby improving the position stability of the battery cell group 310 and ensuring the working performance of the battery cell group 310 to a certain extent.

[0099] In some embodiments, in combination Figure 2 , Figure 3 and Figure 4 As shown, the limiting plates 230 include two, and the two limiting plates 230 are respectively arranged on two opposite sides of the support plate 210 in the third direction. In other words, the limiting plates 230 are arranged on two opposite sides of the support plate 210 in the third direction, so that the limiting plates 230 can be respectively arranged on two opposite sides of the battery cell group 310 in the third direction, so as to limit the displacement of the battery cell group 310 in the third direction and improve the position stability of the battery cell group 310.

[0100] In some embodiments, the limiting plate 230 extends in the first direction and the second direction, which is beneficial to increase the area of ​​the limiting plate 230, thereby facilitating increasing the contact area of ​​the limiting plate 230 with the battery cell group 310, so that the limiting plate 230 can effectively limit the displacement of the battery cell group 310 in the third direction.

[0101] In summary, combined Figure 2 , Figure 3 and Figure 4As shown, the isolation member 200 includes a support plate 210, two connecting plates 220 and two limiting plates 230. The two connecting plates 220 are respectively arranged on the opposite sides of the support plate 210 in the first direction, and the two limiting plates 230 are respectively arranged on the opposite sides of the support plate 210 in the third direction. This not only increases the fixing area between the isolation member 200 and the support beam 120, but also effectively increases the contact area between the isolation member 200 and the battery cell group 310, making it easier to use the isolation member 200 to fix the battery cell group 310.

[0102] It should be noted that, since the isolation member 200 is fixedly connected to the support beam 120 of the frame 100 , when the isolation member 200 is used to fix the battery cell group 310 , the frame 100 can be used to fix the battery cell group 310 , which not only improves the fixing strength, but also eliminates the need for traditional lifting ears, thereby improving the position stability of the battery cell group 310 .

[0103] In some embodiments, the support plate 210 and the limiting plate 230 are integrally formed, so that the support plate 210, the connecting plate 220 and the limiting plate 230 can be formed as an integral part, which reduces the difficulty of forming the isolation member 200, improves the structural stability of the isolation member 200, and is conducive to improving the working performance of the isolation member 200.

[0104] Of course, in some other embodiments, the support plate 210 and the limiting plate 230 may also be formed as separate parts, which is not specifically limited here.

[0105] Through the above-mentioned arrangement, in a specific example, when the battery cell group 310 is disposed in the accommodating space, two adjacent support beams 120 can be used to cooperate to limit the displacement of the battery cell group 310 in the first direction, and two adjacent limiting plates 230 can be used to cooperate to limit the displacement of the battery cell group 310 in the third direction, so as to achieve the purpose of limiting the battery cell group 310 and improve the position stability of the battery cell group 310.

[0106] In some embodiments, in combination Figure 5 and Figure 7 As shown, the support beam 120 is hollow inside, and at least one reinforcement member 123 is provided inside the support beam 120. The reinforcement member 123 is used to increase the structural strength of the support beam 120, thereby increasing the structural strength of the frame 100, ensuring the performance of the frame 100, thereby realizing that the support beam 120 can stably support the battery cell group 310, and the support beam 120 can effectively serve as the outer shell of the battery cell group 310, which is convenient for simplifying the structure of the vehicle.

[0107] In some embodiments, in combination Figure 5 and Figure 7As shown, two reinforcement members 123 are provided in the support beam 120, and the two reinforcement members 123 are respectively provided in the first support beam 121 and the second support beam 122, so as to utilize the reinforcement members 123 to increase the structural strength of the first support beam 121 and the second support beam 122 respectively, thereby effectively increasing the structural strength of the support beam 120.

[0108] At the same time, by respectively arranging the two reinforcement members 123 in the first support beam 121 and the second support beam 122 , it is also helpful to reduce the difficulty of matching the reinforcement member 123 with the support beam 120 , so that the reinforcement member 123 can be effectively arranged in the support beam 120 .

[0109] In some embodiments, the reinforcement member 123 is welded to the support beam 120. It can also be understood that when the reinforcement member 123 is disposed in the first support beam 121, the reinforcement member 123 is welded to the first support beam 121; when the reinforcement member 123 is disposed in the second support beam 122, the reinforcement member 123 is welded to the second support beam 122, so as to realize the welding of the reinforcement member 123 and the support beam 120, thereby facilitating the use of the reinforcement member 123 to increase the structural strength of the support beam 120.

[0110] Of course, in some other embodiments, the reinforcement member 123 and the support beam 120 may also be bonded together.

[0111] Through the above-mentioned arrangement, during the specific assembly process of the support beam 120, a reinforcement member 123 can be firstly arranged in the first support beam 121 and the second support beam 122 respectively. After the reinforcement member 123 is fixedly connected to the first support beam 121 and the second support beam 122, the first support beam 121 and the second support beam 122 are assembled and connected to form the support beam 120 and reduce the difficulty of forming the support beam 120.

[0112] In some embodiments, Figure 7 As shown, the reinforcement member 123 is formed into a plate-like structure, and the reinforcement member 123 has two vertical plates 1231 arranged opposite to each other, so as to increase the contact area between the reinforcement member 123 and the support beam 120 and improve the reinforcement effect of the reinforcement member 123.

[0113] In some other embodiments, the reinforcement member 123 may be formed as a tubular structure with a hollow interior.

[0114] In some embodiments, in combination Figure 1 , Figure 8 and Fig. 9As shown, the spacer 200 includes a support plate 210, and the support plate 210 has accommodating spaces formed on opposite sides in the second direction, and a heat exchange channel 240 is provided in the support plate 210. The heat exchange channel 240 is suitable for filling a heat exchange medium, and the heat exchange medium exchanges heat with the battery cell group 310. Therefore, the spacer 200 is not only used to support the battery cell group 310, but also to adjust the temperature of the battery cell group 310, enriching the function of the spacer 200.

[0115] At the same time, setting the heat exchange channel 240 in the support plate 210 can realize the integration of the isolation component 200 and the heat exchange channel 240, avoid setting a heat exchange component that separately forms the heat exchange channel 240, further simplify the structure of the vehicle, and allow sufficient space in the vehicle to arrange the battery cell group 310, thereby improving the energy density of the battery cell group 310.

[0116] Among them, the heat exchange medium and the battery cell group 310 are heat-exchanged, and the heat exchange medium is mainly used to adjust the temperature of the battery cell group 310, so that the temperature of the battery cell group 310 can be maintained within a suitable temperature range, thereby extending the service life of the battery cell group 310, improving the safety of the battery cell group 310, and ensuring the working performance of the battery cell group 310 to a certain extent.

[0117] It should be noted that adjusting the temperature of the battery cell group 310 mentioned here includes lowering the temperature of the battery cell group 310 and raising the temperature of the battery cell group 310 .

[0118] In a specific example, when the temperature of the battery cell group 310 is too high (such as: the battery cell group 310 works for a long time), the heat exchange medium is used to exchange heat with the battery cell group 310, so as to reduce the temperature of the battery cell group 310 by using the heat exchange medium, and to a certain extent avoid thermal runaway of the battery cell group 310 due to excessive temperature, thereby improving the safety of the battery cell group 310; when the temperature of the battery cell group 310 is too low (such as: the battery cell group 310 works in a low temperature environment), the heat exchange medium is used to exchange heat with the battery cell group 310, so as to increase the temperature of the battery cell group 310 by using the heat exchange medium, thereby improving the charging and discharging performance of the battery cell group 310.

[0119] The heat exchange medium mentioned here is refrigerant, coolant, etc.

[0120] In some embodiments, in combination Figure 1 and Figure 4As shown, the isolation member 200 is provided with an inlet 211 and an outlet 212, and the inlet 211 and the outlet 212 are respectively connected to the heat exchange channel 240. The inlet 211 is used to transport the heat exchange medium toward the heat exchange channel 240, and the outlet 212 is used to lead out the heat exchange medium in the heat exchange channel 240, so that the heat exchange medium can circulate in the heat exchange channel 240, which is beneficial to improving the heat exchange effect of the heat exchange medium, so that the heat exchange medium can effectively maintain the temperature of the battery cell group 310 within a suitable temperature range.

[0121] In some embodiments, Figure 3 As shown, the vehicle body assembly 1000 further includes a heat conducting member 410, which is disposed between the battery cell group 310 and the support plate 210. This allows the heat between the battery cell group 310 and the support plate 210 to be effectively exchanged, thereby achieving heat exchange between the heat exchange medium and the battery cell group 310, and facilitating the use of the heat exchange medium to adjust the temperature of the battery cell group 310.

[0122] The heat conducting element 410 mentioned here can be understood as a heat conducting gasket.

[0123] In some embodiments, the heat conductive member 410 is a heat conductive structural adhesive. When the heat conductive member 410 is disposed between the battery cell group 310 and the support plate 210, not only can the heat between the battery cell group 310 and the isolation member 200 be effectively exchanged, but the heat conductive member 410 can also be used to fix the battery cell group 310 and the isolation member 200, so that the relative position of the battery cell group 310 and the isolation member 200 is stable, thereby improving the position stability of the battery cell group 310.

[0124] It is worth noting that by configuring the heat conductive member 410 as a heat conductive structural adhesive, the heat conductive structural member and the fixed structural member can be integrated, thereby further simplifying the structure of the vehicle and facilitating improving the energy density of the battery cell group 310 .

[0125] In some embodiments, in combination Figure 1 , Figure 2 and Figure 3 As shown, the battery cell group 310 includes multiple groups, and the multiple groups of battery cell groups 310 are arranged in a second direction, and a separator 200 is provided between two adjacent groups of battery cell groups 310, and the second direction intersects with the first direction. The multiple groups of battery cell groups 310 cooperate to have enough electric energy to drive the motor or auxiliary power system of the vehicle, thereby improving the working performance of the vehicle.

[0126] At the same time, by arranging an isolation member 200 between two adjacent groups of battery cell groups 310, each group of battery cell groups 310 can be arranged in a separate accommodation space. On the one hand, it is convenient to use the isolation member 200 and the two adjacent support beams 120 to fix the battery cell group 310. On the other hand, it can also make multiple groups of battery cell groups 310 independent of each other, thereby avoiding electrical connection between multiple groups of battery cell groups 310 to a certain extent, thereby improving the safety of the battery cell groups 310.

[0127] It should be noted that, in the description of the present invention, unless otherwise specified, "multiple groups" means two or more groups.

[0128] In some embodiments, in combination Figure 1 , Figure 2 and Figure 3 As shown, the vehicle body assembly 1000 further includes a protective member 510. Among the multiple battery cell groups 310, the two battery cell groups 310 at the two ends are provided with protective members 510 on the sides facing away from each other. That is, the outer sides of the two battery cell groups 310 at the two ends of the multiple battery cell groups 310 are provided with protective members 510. On the one hand, the protective members 510 are used to protect the battery cell groups 310 and extend the service life of the battery cell groups 310. On the other hand, the protective members 510 can also be used to limit the battery cell groups 310, thereby improving the position stability of the battery cell groups 310 and enhancing the working performance of the battery cell groups 310.

[0129] Through the above-mentioned arrangement, in a specific example, when the battery cell group 310 is disposed in the accommodating space, two adjacent support beams 120 are utilized to cooperate to limit the displacement of the battery cell group 310 in the first direction, two adjacent limiting plates 230 are utilized to cooperate to limit the displacement of the battery cell group 310 in the third direction, and two adjacent isolation members 200 or the isolation member 200 and the protective member 510 are utilized to cooperate to limit the displacement of the battery cell group 310 in the second direction, thereby achieving the purpose of limiting the battery cell group 310 and improving the position stability of the battery cell group 310.

[0130] In some embodiments, in combination Figure 1 , Figure 2 and Figure 3 As shown, the vehicle body assembly 1000 also includes a structural adhesive 810, which is disposed between the protective member 510 and the battery cell group 310 to achieve a fixed connection between the protective member 510 and the battery cell group 310, so that the relative position of the protective member 510 and the battery cell group 310 is stable, thereby facilitating the use of the protective member 510 to protect the battery cell group 310.

[0131] In some embodiments, the body assembly 1000 further includes a floor, a passenger compartment is formed on the top of the floor, multiple battery cell groups 310 are arranged on the side of the floor away from the passenger compartment, and the floor is formed as one of the protective parts 510. In order to realize the integration of the floor and the protective part 510, the floor is used as one of the protective parts 510, and the setting of one protective part 510 is omitted, which simplifies the structure of the body assembly 1000, reduces the manufacturing cost of the vehicle on the one hand, and is also conducive to improving the integration of the whole vehicle, increasing the number of battery cells 311, and facilitating the improvement of the energy density of the battery cell group 310, thereby improving the performance of the battery cell group 310.

[0132] The above description can be understood as follows: the present application eliminates the upper cover of the traditional battery pack, which is beneficial for increasing the space for arranging the battery cell group 310 and improving the energy density of the battery cell group 310 .

[0133] At the same time, by arranging the battery cell group 310 on the side of the floor away from the passenger compartment, on the one hand, the battery cell group 310 can be arranged away from the passenger compartment, which to a certain extent avoids the threat to the driver and passengers when the battery cell group 310 has thermal runaway, thereby improving the safety of vehicle use. On the other hand, it is also beneficial to lower the center of gravity of the vehicle, improve the stability of the vehicle during driving, and thus improve the driving experience.

[0134] It should be noted that when the floor is formed into one of the protective parts 510, it can also be understood that one of the battery cell groups 310 is directly arranged on the floor of the vehicle, which is conducive to forming an integrated design of the battery cell group 310, the floor and the body assembly 1000, so that the battery cell group 310 of the present application can be formed into a CTC (Cell to Chassis) structure, effectively improving the energy density of the battery cell group 310, and reducing the production cost of the battery cell group 310, while making the maintenance and replacement of the battery cell group 310 more convenient.

[0135] In some embodiments, Figure 3 As shown, the vehicle body assembly 1000 further includes a seal 710, which is disposed between the protective member 510 and the isolating member 200 and / or the support beam 120. Here, it means that the seal 710 is disposed between the protective member 510 and the isolating member 200; or, the seal 710 is disposed between the protective member 510 and the support beam 120; or, the seal 710 is disposed between the protective member 510 and the isolating member 200 and the support beam 120, so as to seal the battery cell group 310 in the accommodation space, and to a certain extent prevent foreign matter (such as dust, sharp objects) from entering the accommodation space, which is conducive to extending the service life of the battery cell group 310 and improving the safety of the battery cell group 310.

[0136] The sealing member 710 mentioned here can be understood as a sealing ring or a sealant, etc.

[0137] In some embodiments, in combination Figure 3 , Fig.10 and Fig.11 As shown, the battery cell group 310 includes a plurality of battery cells 311 and a support member 312, wherein the plurality of battery cells 311 are arranged in sequence, and the support member 312 is respectively connected to the plurality of battery cells 311. The battery cell group 310 is configured to include a plurality of battery cells 311 arranged in sequence, which is conducive to improving the overall voltage and capacity of the battery cell group 310, thereby improving the working performance of the battery cell group 310.

[0138] At the same time, by connecting the support members 312 to the multiple battery cells 311 respectively, the support members 312 can be used to limit the relative positions of the multiple battery cells 311, so that the relative positions of the multiple battery cells 311 are stable, thereby improving the structural stability of the battery cell group 310 and ensuring the working performance of the battery cell group 310 to a certain extent.

[0139] In some embodiments, in combination Figure 3 , Fig.10 and Fig.11 As shown, when a protective member 510 is provided on the outer side of the battery cell group 310, the support member 312 connects the multiple battery cells 311 and one end of the support member 312 is fixedly connected to the protective member 510, so that the support member 312 is supported by the protective member 510, and the position stability of the support member 312 is improved, so that the support member 312 can effectively limit the relative positions of the multiple battery cells 311, so that the relative positions of the multiple battery cells 311 are stable, thereby improving the structural stability of the battery cell group 310.
