[0006] In some embodiments, the reinforcing component includes a collapsible member and a buffer assembly. The collapsible member is located between the sill beam and the buffer assembly and is connected to the sill beam and the buffer assembly respectively. The collapsible member cooperates with the sill beam and the battery basin to form a buffer cavity. The collapsible member is configured to deform under the push of the sill beam so that the buffer assembly moves closer to the sill beam and the battery basin.
[0007] In some embodiments, the collapse member includes a first connecting portion, a bending portion, and a second connecting portion connected in sequence.

[0008] In some embodiments, the buffer assembly includes a support and a reinforcement. The support extends in the spaced direction of the two sill beams, and the reinforcement has a first connecting surface and a second connecting surface disposed opposite to each other in the spaced direction. The first connecting surface is connected to the support, and the second connecting surface is connected to the collapse member. In the direction from the second connecting surface to the first connecting surface, the size of the reinforcement gradually decreases in the direction perpendicular to the spaced direction.

By forming a buffer cavity between the reinforcing component, the battery tray, and the sill beams, the buffer cavity can effectively absorb impact energy. When the impact force on the sill beams is large, the reinforcing component can compress the buffer cavity under the push of the sill beams, allowing the buffer cavity to fully absorb the impact energy. Furthermore, the reinforcing component can approach and contact the battery tray, thereby directly providing support and protection for the battery tray, fully absorbing and dispersing impact energy, improving the structural strength of the vehicle body assembly, and effectively reducing the risk of battery damage due to deformation of the battery tray.

[0035] As electric vehicles become increasingly popular, people have higher and higher requirements for their collision safety, battery collision safety, and ride comfort.
[0036] Vehicles may face various types of collisions, such as frontal and side collisions. Side collisions include pole collisions, which pose a higher risk of damage to the battery and other components.

[0039] Combination Figures 2-4 As shown, Figure 2 This is a first structural schematic diagram of a vehicle body assembly according to one or more embodiments of this application; Figure 3 This is a second structural schematic diagram of a vehicle body assembly according to one or more embodiments of this application; Figure 4 It is based on Figure 3 The diagram shows a cross-sectional view of the body assembly along the AA direction.
[0040] To address the aforementioned issues, this application provides a vehicle body assembly 2, which includes two spaced-apart sill beams 10, a battery tray 20, and a reinforcing assembly 30. The battery tray 20 is located between the two sill beams 10 and is connected to each of the two sill beams 10, and the battery tray 20 forms a receiving cavity 21. The reinforcing assembly 30 is at least partially located within the receiving cavity 21 and is connected to each of the two sill beams 10. The reinforcing assembly 30 is spaced apart from the battery tray 20 to cooperate with the battery tray 20 and the sill beams 10 to form a buffer cavity 40. The reinforcing assembly 30 is configured to compress the buffer cavity 40 and move closer to the battery tray 20 under the push of the sill beams 10.
[0041] The sill beam 10 can absorb and disperse impact energy in the event of a collision with the vehicle 1, thereby providing support and protection for the passenger compartment and other components of the vehicle 1. The battery basin 20 has a receiving cavity 21, which can accommodate battery cells, battery packs, and other energy storage devices. A battery cell is the smallest unit that makes up a battery pack, and a battery pack can be a whole composed of multiple battery cells connected in series, parallel, or in a hybrid manner. The battery basin 20 provides installation space, support, and protection for the energy storage devices within the receiving cavity 21. The battery basin 20 can also transmit force between the two sill beams 10. The reinforcing component 30 is connected to the two sill beams 10 respectively. It is understood that the reinforcing component 30 can also transmit force between the two sill beams 10. For example, when one sill beam 10 is hit, the impact force can be transmitted to the other sill beam 10 through the battery basin 20. The impact force can also be transmitted to the other sill beam 10 through the reinforcing component 30, so that the impact force can be transmitted between the two sill beams 10 through different force transmission paths, which is convenient for absorbing and dispersing the impact energy. The reinforcing component 30 is at least partially located within the receiving cavity 21. Exemplarily, the battery basin 20 may be an open basin shape, thereby defining the receiving cavity 21 through its side walls and bottom wall. The opening of the battery basin 20 may communicate with the outside of the receiving cavity 21. The reinforcing component 30 may be partially or completely located within the receiving cavity 21. Specifically, the reinforcing component 30 may be partially located within the receiving cavity 21, partially located outside the receiving cavity 21 through the opening, and connected to the sill beam 10 outside the receiving cavity 21. Alternatively, the reinforcing component 30 may be completely located within the receiving cavity 21, and the sill beam 10 may extend to the opening of the battery basin 20 and connect to the reinforcing component 30. The reinforcing component 30 is spaced apart from the battery basin 20. Exemplarily, the sill beams 10 on both sides may provide support for the reinforcing component 30 so that the reinforcing component 30 is at least partially located within the receiving cavity 21 but does not directly contact the battery basin 20. A buffer cavity 40 can be formed between the reinforcing component 30, the battery basin 20, and the sill beam 10. Understandably, when the sill beam 10 is subjected to an impact, the impact force is transmitted to the battery basin 20 and the reinforcing component 30. The sill beam 10 can push the battery basin 20 and the reinforcing component 30, thereby causing the reinforcing component 30 to compress the buffer cavity 40 to a certain extent. Under a small impact force, the buffer cavity 40 can directly and completely absorb the impact energy. Under a large impact force, the reinforcing component 30 compresses the buffer cavity 40 to a greater extent, and the reinforcing component 30 is also closer to the battery basin 20. Under a sufficiently large impact force, the reinforcing component 30 can directly contact the battery basin 20 and directly transmit the impact force through the battery basin 20, thereby directly providing support for the battery basin 20 and reducing the risk of damage to the battery and other components in the housing cavity 21 due to deformation caused by excessive impact force.
[0042] Through the above implementation, when the sill beam 10 is subjected to a collision, the reinforcing component 30 can transmit the collision force between the two sill beams 10. By forming a buffer cavity 40 between the reinforcing component 30, the battery basin 20, and the sill beam 10, the buffer cavity 40 can effectively absorb the collision energy. When the sill beam 10 is subjected to a large collision force, the reinforcing component 30 can squeeze the buffer cavity 40 under the push of the sill beam 10, so that the buffer cavity 40 can fully absorb the collision energy. Furthermore, the reinforcing component 30 can approach and contact the battery basin 20, thereby directly providing support and protection for the battery basin 20, fully absorbing and dispersing the collision energy, improving the structural strength of the vehicle body component 2, and effectively reducing the risk of battery damage caused by deformation of the battery basin 20.
[0043] In some embodiments, the reinforcing component 30 includes a collapsible member 31 and a buffer component 32. The collapsible member 31 is located between the sill beam 10 and the buffer component 32, and is connected to both the sill beam 10 and the buffer component 32. The collapsible member 31, together with the sill beam 10 and the battery basin 20, forms a buffer cavity 40. The collapsible member 31 is configured to deform under the push of the sill beam 10, so that the buffer component 32 moves closer to the sill beam 10 and the battery basin 20. Exemplarily, when one side of the sill beam 10 is impacted, the impact force can be transmitted through the collapsible member 31 to the buffer component 32, and then through the buffer component 32 to the other side of the sill beam 10. The buffer component 32 can be used to absorb and disperse the impact energy. It should be noted that the collapsible member 31 may have a certain degree of elasticity. When the impact force is small, the collapsible member 31 may undergo elastic deformation within a certain range and compress the buffer cavity 40, thereby stably transmitting the impact force to the buffer component 32. After the impact energy is dispersed and absorbed, the collapsible member 31 can return to its original shape. Under a large impact force, the crumple zone 31 deforms significantly, collapsing between the sill beam 10 and the battery tray 20, thus compressing the buffer cavity 40 and absorbing the impact energy. When the impact force reaches the maximum threshold that the crumple zone 31 can withstand, it completely collapses, fully compressing the buffer cavity 40, allowing the buffer assembly 32 to directly contact the battery tray 20. This facilitates the buffer assembly 32 receiving impact energy directly from the battery tray 20, providing direct support and protection for it. The number of crumple zones 31 can be one or two. When there is only one crumple zone 31, it is located between one side of the sill beam 10 and the buffer assembly 32, with the end of the buffer assembly 32 furthest from the crumple zone 31 directly contacting the other side of the sill beam 10. When there are two crumple zones 31, they are located at opposite ends of the buffer assembly 32, allowing each crumple zone 31 to connect one end of the sill beam 10 and the buffer assembly 32.
[0044] In some embodiments, the collapse member 31 includes a first connecting portion 311, a bending portion 312, and a second connecting portion 313 connected in sequence. The first connecting portion 311 is connected to one of the two sill beams 10 along the interval direction x1. The second connecting portion 313 is connected to the buffer assembly 32 along the interval direction x1. The bending portion 312 is bent to the first connecting portion 311 and the second connecting portion 313 respectively. The bending portion 312 and the second connecting portion 313 cooperate with the sill beam 10 and the battery basin 20 to form a buffer cavity 40. Exemplarily, the first connecting portion 311 can be connected to the sill beam 10 via its main surface facing the sill beam 10, and the second connecting portion 313 can be connected to the sill beam 10 via its main surface facing the buffer assembly 32. The bending portion 312 can be bent relative to the respective main surfaces of the first connecting portion 311 and the second connecting portion 313. Specifically, the first connecting portion 311 can extend in a direction perpendicular to the interval direction x1, the second connecting portion 313 can extend in a direction perpendicular to the interval direction x1, and the bending portion 312 extends in a direction inclined relative to the interval direction x1, so that the first connecting portion 311, the bending portion 312 and the second connecting portion 313 form a shape similar to "Z". As an example, the first connecting portion 311 can extend in the direction from the opening of the battery basin 20 to the bottom wall, and the second connecting portion 313 can also extend in the direction from the opening of the battery basin 20 to the bottom wall. The bending portion 312 can be connected to the end of the first connecting portion 311 near the bottom wall and the end of the second connecting portion 313 away from the bottom wall, respectively. The bending portion 312 and the second connecting portion 313, together with the sill beam 10 and the battery basin 20, form a buffer cavity 40. Understandably, when the sill beam 10 is subjected to a collision, it pushes the crumple member 31, causing deformation between the first connecting portion 311 and the bending portion 312, and between the second connecting portion 313 and the bending portion 312. This causes the second connecting portion 313 and the bending portion 312 to move closer to the battery basin 20. Thus, through the connection and cooperation of the first connecting portion 311, the bending portion 312, and the second connecting portion 313, the collision force is easily transmitted from the sill beam 10 to the buffer assembly 32. Simultaneously, relative bending deformation can occur between the bending portion 312 and the first connecting portion 311, the bending portion 312, and the second connecting portion 313, allowing the bending portion 312 and the second connecting portion 313 to compress the buffer cavity 40. This allows the buffer cavity 40 to more fully absorb and disperse collision energy, improving the reliability of the vehicle body assembly 2.
[0045] In some application scenarios, the vehicle body assembly 2 also includes a fastener. The battery basin 20 includes a flange that connects to the side wall of the battery basin 20 and extends away from the receiving cavity 21. The fastener is used to connect the flange to the sill beam 10. Specifically, the flange may have a first mounting hole, and the sill beam 10 may have a second mounting hole. The fastener can be inserted into the first and second mounting holes to fix the sill beam 10 to the battery basin 20. The fastener can be, but is not limited to, bolts, screws, etc. In some application scenarios, the second mounting hole may communicate with multiple second reinforcing cavities 11, and the fastener may pass through multiple second reinforcing cavities 11 to facilitate the transfer of collision energy from the second reinforcing cavities 11 to the battery basin 20 via the fastener. When the fastener is a bolt, the vehicle body assembly 2 also includes a nut. The nut may be located in any one of the multiple second reinforcing cavities 11 through which the bolt passes and abuts against the side wall of the second reinforcing cavity 11 to fix the bolt. In some application scenarios, the vehicle body component 2 also includes a reinforcing sleeve. The reinforcing sleeve can be fitted onto the fastener and located inside the first mounting hole. The fastener is connected to the first mounting hole through the sleeve. It can be understood that the reinforcing sleeve can improve the structural strength at the connection between the fastener and the first mounting hole, thereby improving the connection stability between the fastener and the battery basin 20, and facilitating the transfer of collision energy to the battery basin 20 through the fastener.
[0046] In some embodiments, the battery basin 20 includes a plurality of reinforcing plates 22, which are stacked in the opening direction x2 of the battery basin 20. At least a portion of the reinforcing plates 22 is connected to the sill beam 10. A third reinforcing cavity 23 is formed between two adjacent reinforcing plates 22, and the third reinforcing cavity 23 extends in the direction from the sill beam 10 to the reinforcing assembly 30. The opening direction x2 of the battery basin 20 may be perpendicular to the bottom wall of the battery basin 20. It is understood that when the sill beam 10 is subjected to an impact, the impact energy can be transferred to the plurality of reinforcing plates 22. The third reinforcing cavity 23 formed between two adjacent reinforcing plates 22 allows the impact energy to be transferred in the direction from the sill beam 10 to the reinforcing assembly 30 through the reinforcing plates 22 and the third reinforcing cavity 23. The third reinforcing cavity 23 can be used to absorb and disperse the impact energy. In the case of excessive impact force, the two adjacent reinforcing plates 22 cooperate to compress the third reinforcing cavity 23 between them, thereby causing the third reinforcing cavity 23 to collapse and thus fully absorb the impact energy. As an example, at least a portion of the plurality of reinforcing plates 22 may be exposed in the receiving cavity 21, thereby defining the sidewalls and bottom wall of the battery basin 20. The reinforcing assembly 30 may cooperate with the reinforcing plates 22 and the sill beam 10 to form a buffer cavity 40. When the reinforcing assembly 30 is close to and in contact with the battery basin 20, the portion of the reinforcing plates 22 exposed in the receiving cavity 21 may contact the reinforcing assembly 30, thereby allowing the impact energy to be directly transferred to the reinforcing assembly 30 through the reinforcing plates 22.
[0047] Combination Figures 4-8 , Figure 5 This is a schematic diagram of the structure of a reinforcing component of a vehicle body assembly according to one or more embodiments of this application; Figure 6 This is a first structural schematic diagram of a reinforcement member of a vehicle body assembly according to one or more embodiments of this application; Figure 7 This is a second structural schematic diagram of a reinforcement member of a vehicle body assembly according to one or more embodiments of this application; Figure 8 This is a third structural schematic diagram of a reinforcement member of a vehicle body assembly according to one or more embodiments of this application.
[0048] In some embodiments, the buffer assembly 32 includes a support member 321 and a reinforcement member 322. The support member 321 extends in a spaced direction x1 between the two sill beams 10. The reinforcement member 322 has a first connecting surface 3221 and a second connecting surface 3222 disposed opposite to each other in the spaced direction x1. The first connecting surface 3221 is connected to the support member 321, and the second connecting surface 3222 is connected to the collapse member 31. In the direction from the second connecting surface 3222 to the first connecting surface 3221, the size of the reinforcement member 322 gradually decreases in the direction perpendicular to the spaced direction x1. The support member 321 can serve as the main body of the buffer assembly 32. The support member 321 extends in the interval direction x1 and is connected to the collapsible member 31 via the reinforcing member 322. Exemplarily, when there are two collapsible members 31, there can also be two reinforcing members 322. The two collapsible members 31 are located at opposite ends of the support member 321, with one reinforcing member 322 located between one of the collapsible members 31 and the support member 321, and the other reinforcing member 322 located between the other collapsible member 31 and the support member 321. It is understood that the two reinforcing members 322 can be arranged symmetrically relative to the support member 321. The reinforcing member 322 is connected to the support member 321 via a first connecting surface 3221 and to the collapsible member 31 via a second connecting surface 3222. In the event of a collision with the sill beam 10, the impact force can be transmitted through the collapsible member 31 to the second connecting surface 3222 and then to the support member 321 via the first connecting surface 3221. In the direction from the second connecting surface 3222 to the first connecting surface 3221, the size of the reinforcing member 322 gradually decreases in the direction perpendicular to the spacing direction x1. For example, viewed along the direction from the opening of the battery basin 20 to the bottom wall, the width of the reinforcing member 322 gradually decreases in the direction from the second connecting surface 3222 to the first connecting surface 3221. It should be noted that by gradually decreasing the size of the reinforcing member 322 in the direction perpendicular to the spacing direction x1 in the direction from the second connecting surface 3222 to the first connecting surface 3221, the reinforcing member 322 can receive impact energy from the collapsible member 31 through the larger side closer to the second connecting surface 3222, and the impact energy is concentrated and transferred to the smaller side closer to the first connecting surface 3221 in the direction from the second connecting surface 3222 to the first connecting surface 3221. During this process, the impact energy gradually attenuates, and it also facilitates the stable transfer of the impact energy to the support member 321, which is beneficial for the support member 321 to effectively resist the impact energy.
[0049] In some embodiments, the reinforcing member 322 further has a first surface 3223 and a second surface 3224 disposed opposite to each other, the first surface 3223 and the second surface 3224 respectively connecting the first connecting surface 3221 and the second connecting surface 3222, and the reinforcing member 322 is formed with a plurality of first reinforcing cavities 3225, each of the first reinforcing cavities 3225 penetrating the first surface 3223 and the second surface 3224. The first surface 3223 is connected to the first connecting surface 3221 and the second connecting surface 3222, respectively. The second surface 3224 is also connected to the first connecting surface 3221 and the second connecting surface 3222, respectively. Exemplarily, the first surface 3223 and the second surface 3224 can be arranged opposite to each other in a direction perpendicular to the spacing direction x1. Specifically, the first surface 3223 and the second surface 3224 can be arranged opposite to each other in the direction from the bottom wall to the opening of the battery basin 20. Each first reinforcing cavity 3225 penetrates through the first surface 3223 and the second surface 3224. When viewed along the direction from the first surface 3223 to the second surface 3224, the shape of the multiple first reinforcing cavities 3225 can be, but is not limited to, trapezoidal, rectangular, triangular, circular, etc. The multiple first reinforcing cavities 3225 can be arranged simultaneously along the spacing direction x1 and in a direction perpendicular to the spacing direction x1. It is understood that the collision energy can be fully absorbed through the multiple first reinforcing cavities 3225. Under excessive impact force, the first reinforcing cavity 3225 can also collapse, thereby fully absorbing the impact energy and improving the structural strength of the buffer assembly 32.
[0050] In some application scenarios, the reinforcing member 322 is symmetrically arranged with respect to a plane of symmetry parallel to the interval direction x1. The reinforcing member 322 includes multiple spaced-apart extension ribs, which cooperate to define multiple first reinforcing cavities 3225. In the direction from the second connecting surface 3222 to the first connecting surface 3221, each extension rib extends from the side away from the plane of symmetry to the side closer to the plane of symmetry, or extends in a direction parallel to the plane of symmetry. This facilitates the concentrated transfer of collision energy to the first connecting surface 3221 through multiple extension ribs, thereby helping to stably transfer the collision energy to the support member 321.
[0051] In some embodiments, the first surface 3223 and the second surface 3224 are disposed opposite to each other in the opening direction x2 of the battery basin 20. The second surface 3224 is closer to the bottom wall of the battery basin 20 than the first surface 3223. The second surface 3224 includes a first sub-surface 3224a and a second sub-surface 3224b that are connected to each other. The first sub-surface 3224a is connected to the first connecting surface 3221, and the second sub-surface 3224b is connected to the second connecting surface 3222. The first sub-surface 3224a is parallel to the bottom wall of the battery basin 20, and the second sub-surface 3224b is inclined relative to the first sub-surface 3224a. The opening direction x2 of the battery basin 20 may be perpendicular to the bottom wall of the battery basin 20. Understandably, collision energy can be transferred from the second connecting surface 3222 to the first sub-surface 3224a via the inclined second sub-surface 3224b, and then to the first connecting surface 3221 via the first sub-surface 3224a, and further to the support member 321. This facilitates better transmission of collision force by the reinforcing member 322. When the sill beam 10 is impacted, the reinforcing member 322 can move closer to the battery basin 20 under the push of the sill beam 10. In cases of excessive collision force, the reinforcing member 322 can contact the battery basin 20 via the first sub-surface 3224a and the second sub-surface 3224b, thereby increasing the contact area between the reinforcing member 322 and the battery basin 20 and improving the contact stability between them. In some application scenarios, the reinforcing member 322 can contact the side wall and bottom wall of the battery basin 20, the second sub-surface 3224b can contact the bottom wall of the battery basin 20, and the first sub-surface 3224a can contact the side wall of the battery basin 20. The inclined second sub-surface 3224b allows the collision energy to be transferred to the reinforcing member 322 in a direction perpendicular to the second sub-surface 3224b, which increases the transmission path of the collision energy. This is beneficial for the reinforcing member 322 to absorb and disperse the collision energy on the battery basin 20, and reduces the risk of damage to the battery and other energy storage devices caused by deformation of the battery basin 20. In some application scenarios, the sidewall of the battery basin 20 is also inclined relative to the bottom wall. Optionally, the second sub-surface 3224b is parallel to the sidewall of the battery basin 20. It can be understood that when the reinforcing member 322 is in contact with the battery basin 20, the inclined second sub-surface 3224b can abut against the inclined sidewall of the battery basin 20, further improving the stability of the collision force transmission between the battery basin 20 and the reinforcing member 322. At the same time, the sidewall of the battery basin 20 can cooperate with the second sub-surface 3224b to prevent the first sub-surface 3224a from rotating towards the sidewall of the battery basin 20, mitigating the risk that the first sub-surface 3224a will continue to rotate due to the large collision force, resulting in the first sub-surface 3224a being relatively parallel to the sidewall of the battery basin 20. That is, it mitigates the risk of the reinforcing member 322 overturning and tipping over under the push of the sill beam 10, and improves the reliability of the body assembly 2.
[0052] In some embodiments, the first connecting surface 3221 is provided with a connecting groove 3221a that is recessed relative to the support member 321, and the support member 321 is inserted into the connecting groove 3221a. Thus, by inserting the support member 321 into the connecting groove 3221a, the contact area between the first connecting surface 3221 and the support member 321 is increased, improving the connection stability between the support member 321 and the reinforcing member 322. Simultaneously, the first connecting surface 3221 can form the bottom wall and side wall of the connecting groove 3221a, allowing the reinforcing member 322 to contact the support member 321 from multiple directions via the bottom wall and side wall of the connecting groove 3221a, thereby facilitating the stable transfer of collision energy from the reinforcing member 322 to the support member 321. Specifically, the support member 321 can be inserted into the connecting groove 3221a in various ways. For example, the support member 321 can be, but is not limited to, interference fit with the connecting groove 3221a, welding with the connecting groove 3221a, etc. The support member 321 can also be connected to the connecting groove 3221a in multiple ways at the same time. For example, the support member 321 can be interference fit with the connecting groove 3221a and welding at the same time.
[0053] In some embodiments, the sill beam 10 has a plurality of second reinforcing cavities 11. Some of the second reinforcing cavities 11 are arranged along the direction from the sill beam 10 to the reinforcing assembly 30, and some are arranged along the direction from the sill beam 10 to the bottom wall of the battery basin 20. The sill beam 10 extends in a direction perpendicular to the spacing direction x1. The second reinforcing cavities 11 may penetrate opposite sides of the sill beam 10 in the direction of its extension. Viewed along the direction of the sill beam 10, the shapes of the plurality of second reinforcing cavities 11 may include, but are not limited to, square, trapezoidal, triangular, etc. The width dimensions of the plurality of second reinforcing cavities 11 in the spacing direction x1 may be the same or different. For example, the width dimension of a portion of the second reinforcing cavities 11 located on the side away from the battery basin 20 may be smaller than the width dimension of a portion of the second reinforcing cavities 11 located on the side closer to the battery basin 20. Understandably, some of the second reinforcing cavities 11 are arranged along the direction from the sill beam 10 to the reinforcing assembly 30. In the event of a collision with the sill beam 10, the impact force can be transmitted to the reinforcing assembly 30 through the multiple second reinforcing cavities 11. Some of the second reinforcing cavities 11 are also arranged along the direction from the sill beam 10 to the bottom wall of the battery basin 20, allowing the impact force to be transmitted to the battery basin 20 along these cavities. The multiple second reinforcing cavities 11 effectively absorb collision energy, further improving the structural strength and collision resistance of the vehicle body assembly 2.

[0055] In some application scenarios, the support member 321 forms multiple fourth reinforcing cavities 3211. Each fourth reinforcing cavity 3211 penetrates the opposite two surfaces of the support member 321 along the interval direction x1, and the multiple fourth reinforcing cavities 3211 are arranged in a direction perpendicular to the interval direction x1. Viewed along the interval direction x1, the shape of each fourth reinforcing cavity 3211 can be, but is not limited to, rectangular, trapezoidal, etc. It is understood that the support member 321 can effectively absorb and disperse collision energy through the multiple fourth reinforcing cavities 3211, thereby effectively improving the structural strength of the support member 321.
[0056] In summary, the vehicle body assembly 2 provided in this application includes two spaced-apart sill beams 10, a battery basin 20, and a reinforcing assembly 30. The battery basin 20 is located between the two sill beams 10 and is connected to each of the two sill beams 10. The battery basin 20 forms a receiving cavity 21. The reinforcing assembly 30 is at least partially located within the receiving cavity 21 and is connected to each of the two sill beams 10. The reinforcing assembly 30 is spaced apart from the battery basin 20 to cooperate with the battery basin 20 and the sill beams 10 to form a buffer cavity 40. The reinforcing assembly 30 is configured to squeeze the buffer cavity 40 and move closer to the battery basin 20 under the push of the sill beams 10. Through the above implementation, when the sill beam 10 is subjected to a collision, the reinforcing component 30 can transmit the collision force between the two sill beams 10. By forming a buffer cavity 40 between the reinforcing component 30, the battery basin 20, and the sill beam 10, the buffer cavity 40 can effectively absorb the collision energy. When the sill beam 10 is subjected to a large collision force, the reinforcing component 30 can squeeze the buffer cavity 40 under the push of the sill beam 10, so that the buffer cavity 40 can fully absorb the collision energy. Furthermore, the reinforcing component 30 can approach and contact the battery basin 20, thereby directly providing support and protection for the battery basin 20, fully absorbing and dispersing the collision energy, improving the structural strength of the vehicle body component 2, and effectively reducing the risk of battery damage caused by deformation of the battery basin 20.
