[0049] For a better understanding of the technical solutions of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0050] It should be clear that the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this application.

[0051] The terms used in the embodiments of this application are only for the purpose of describing specific embodiments, and are not intended to limit this application. The singular forms "a", "the" and "said" used in the embodiments of this application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0052] It should be understood that the term " / " used herein is only a description of the association relationship between associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0053] As Figure 1 shown, the embodiments of this application provide a vehicle body structure. The vehicle body structure includes a first front girder 1, a second front girder 2, a front girder sealing plate 3, a first reinforcing plate 6 and a front panel cross - beam 4. The first front girder 1 and the second front girder 2 are arranged in sequence and connected to each other along a first direction. The first direction is the length direction of the vehicle body structure, as Figure 1As shown, the X direction is the first direction. There are two first front crossbeams 1 and two second front crossbeams 2. The two first front crossbeams 1 and the second front crossbeams 2 are symmetrically arranged on both sides of the vehicle body structure along the second direction, which is convenient for the overall structural design and layout of the vehicle. The second direction is the width direction of the vehicle body structure. For example, Figure 1 as shown, the Y direction is the second direction. The first front crossbeam 1 extends along the first direction and is used to withstand the frontal collision of the vehicle body structure. To meet the actual needs, the first front crossbeam 1 can have a certain angle with the first direction, or a part of the first front crossbeam 1 has a certain angle with the first direction, so as to better absorb the collision energy and improve the safety of the vehicle body structure. One end of the second front crossbeam 2 is connected to the first front crossbeam 1. The width dimension of the end of the second front crossbeam 2 connected to the first front crossbeam 1 can be the same as or similar to that of the first front crossbeam 1, which is convenient for their connection. The end of the second front crossbeam 2 away from the first front crossbeam 1 can be set in a shape such as a fan or a triangle with a gradually increasing width dimension, so as to better disperse the collision force. The second front crossbeam 2 and the first front crossbeam 1 can be connected to each other by welding, so as to improve the connection stability and structural strength.

[0054] The front panel crossbeam 4 extends along the second direction and connects the two first front crossbeams 1 located on both sides of the vehicle body structure. When the vehicle body structure is collided, especially when the vehicle body structure is impacted in the second direction, the impact received by the first front crossbeam 1 can be transmitted along the second direction through the front panel crossbeam 4, so as to better achieve energy absorption. Along the first direction, the connection position of the front panel crossbeam 4 and the first front crossbeam 1 corresponds to the connection position of the first front crossbeam 1 and the second front crossbeam 2. When one side of the vehicle body structure is impacted, the front panel crossbeam 4 can transmit the impact force to the side that is not impacted, reducing the probability of the separation between the first front crossbeam 1 and the second front crossbeam 2, and thus reducing the possibility of serious deformation of the first front crossbeam 1 and the second front crossbeam 2, and further improving the vehicle body strength and safety. The front panel crossbeam 4 and the first front crossbeam 1 can be connected to each other by setting the front crossbeam connector 41 to improve the connection stability.

[0055] For example, Figure 5 and Figure 6As shown, there is an installation space 5 between the first front girder 1, the second front girder 2 and the front girder sealing plate 3. Specifically, parts of the first front girder 1 and the second front girder 2 are bent along the second direction and connected to each other, and further cooperate with the front girder sealing plate 3 to enclose a relatively closed installation space 5. The bent parts of the first front girder 1 and the second front girder 2 can overlap and connect with each other, and further cooperate with the front girder sealing plate 3, so as to improve the strength of the connected parts. The three enclose and connect with each other to form a structure with a cavity, and the cavity structure is the installation space 5. On the one hand, the installation space 5 can help reduce the weight of the body structure, and on the other hand, it can improve the overall strength of the body structure, enabling it to withstand stronger collisions. The installation space 5 does not necessarily have a strictly sealed structure. For the convenience of structural arrangement, the first front girder 1 and the second front girder 2 can be provided with openings for installing connecting parts such as bolts, as long as the first front girder 1, the second front girder 2 and the front girder sealing plate 3 enclose to form a tubular or similar tubular structure.

[0056] The first reinforcing plate 6 is located inside the installation space 5. The first reinforcing plate 6 is respectively connected to the first front girder 1, the second front girder 2 and the front girder sealing plate 3. The position of the first reinforcing plate 6 in the first direction corresponds to that of the front panel cross beam 4. The position of the first reinforcing plate 6 in the first direction is the same as or close to that of the front panel cross beam 4, which is convenient for the transfer of energy during impact. The first reinforcing plate 6 is used to support the first front girder 1, the second front girder 2 and the front girder sealing plate 3. When the body structure is impacted, especially when the body structure is impacted in the second direction, the first reinforcing plate 6 can transfer the impact along the second direction to the front panel cross beam 4, and further transfer the impact to the first front girder 1 and the second front girder 2 on the other side that are not impacted through the front panel cross beam 4, so that both sides of the body structure can better absorb energy during collision, and the first reinforcing plate 6 can also deform to absorb energy, improving the anti-impact performance and safety of the body structure.

[0057] As Figure 9 and Figure 10 shown, in a possible implementation manner, the first reinforcing plate 6 includes a main body portion 61 and a flanging 62. The flanging 62 is arranged along the circumference of the main body portion 61, and the flanging 62 is connected to the first front girder 1, the second front girder 2 and the front girder sealing plate 3.

[0058] The main body part 61 can be set as a sheet or plate shape, which is used to support the first front crossmember 1, the second front crossmember 2 and the front crossmember sealing plate 3 in the second direction. When the vehicle body structure is impacted, it can transmit the impact along the second direction, improving the safety of the vehicle body structure. The edge part of the main body part 61 is provided with a flanging 62, and the flanging 62 is respectively connected to the first front crossmember 1, the second front crossmember 2 and the front crossmember sealing plate 3, and can be connected by welding to improve the connection stability. The flanging 62 can improve the overall strength of the first reinforcement plate 6 and reduce the possibility of deformation of the first reinforcement plate 6. The flanging 62 extends along the first direction, which can provide a large contact area with the first front crossmember 1, the second front crossmember 2 and the front crossmember sealing plate 3. The flanging 62 can be integrally formed with the main body part 61, thereby improving the overall strength of the first reinforcement plate 6.

[0059] As Figure 10 shown, in a possible implementation manner, the main body part 61 has a stepped hole 63, and the stepped hole 63 penetrates the main body part 61 along the first direction, and the inner wall of the stepped hole protrudes along the first direction.

[0060] Setting the stepped hole 63 in the main body part 61 can reduce the weight of the first reinforcement plate 6 and improve the structural strength of the first reinforcement plate 6. The inner wall of the stepped hole 63 can be set in a form that protrudes along the first direction relative to the main body part 61. The inner wall of the stepped hole 63 can be set as an arc shape and extend along the first direction, which can improve the structural strength of the main body part 61. During the processing of the vehicle body structure, it needs to be processed through the electrophoretic coating process. During processing, the parts need to be placed in the electrophoretic solution, and the electrophoretic solution can flow smoothly through the stepped hole 63 inside the installation space 5, facilitating the electrophoretic coating processing.

[0061] As Figure 6 and Figure 7 shown, in a possible implementation manner, the vehicle body structure includes a subframe mounting point 9, and the subframe mounting point 9 is arranged on the second front crossmember 2.

[0062] The subframe mounting point 9 is used to set and install the subframe. The subframe mounting point 9 can be set in the form of a through hole, and a subframe fixing member 91 can be set at the subframe mounting point 9 for installing and fixing the subframe. The through hole of the subframe mounting point 9 can pass through the second front crossmember 2 and other components overlapping with the second front crossmember 2, thereby facilitating the setting of the subframe fixing member 91. The subframe fixing member 91 can be a connecting member such as a bolt, which is convenient for setting and installation.

[0063] As Figure 6 shown, in a possible implementation manner, the vehicle body structure includes a plurality of subframe mounting points 9, and at least one subframe mounting point 9 corresponds to the position of the first reinforcement plate 6 along the first direction.

[0064] The subframe mounting point 9 is adjacently arranged to the first reinforcing plate 6. When the vehicle body is impacted, the first reinforcing plate 6 can transfer the impact force to the subframe through the subframe connecting member 91 arranged at the subframe mounting point 9, thereby dispersing the impact energy and improving the crashworthiness of the vehicle body structure. The specific position of the subframe mounting point 9 can be set according to actual requirements. For example, the subframe mounting point 9 can be arranged on the front side or the rear side of the first reinforcing plate 6 along the first direction, and the distance between the subframe mounting point 9 and the first reinforcing plate 6 can also be reasonably set according to actual requirements. The subframe connecting member 91 can be a bolt or the like, as long as it can transfer the impact energy to the subframe connecting member 91 or the subframe mounted at the subframe mounting point 9 through the first reinforcing plate 6, and there is no limitation here.

[0065] As Figure 1 and Figure 5 shown, in a possible implementation manner, the vehicle body structure includes a second reinforcing plate 7. The second reinforcing plate 7 is stacked and connected to the second front beam 2, and the second reinforcing plate 7 is connected to the front beam sealing plate 3.

[0066] The second reinforcing plate 7 covers the part of the second front beam 2 extending out of the installation space 5. The second reinforcing plate 7 can also cover the part of the second front beam 2 located inside the installation space 5. The second reinforcing plate 7 covers the position where the width dimension of the second front beam 2 is larger in the second direction, thereby improving the structural strength of the second front beam 2. When the second front beam 2 is impacted by the impact transmitted from the first front beam 1, it can resist deformation and protect the position area of the vehicle cockpit. The front beam sealing plate 3 is located at the edge of the second front beam 2. One side of the second reinforcing plate 7 along the first direction is connected to the front beam sealing plate 3, and the other side is connected to the second front beam 2. The second reinforcing plate 7 can support the front beam sealing plate 3.

[0067] As Figure 1 , Figure 5 , Figure 6 and Figure 8 shown, in a possible implementation manner, the vehicle body structure includes a third reinforcing plate 8. The third reinforcing plate 8 is connected to the second reinforcing plate 7. One end of the third reinforcing plate 8 is located inside the installation space 5 and is connected to the first front beam 1, and the other end of the third reinforcing plate 8 is located outside the installation space 5 and is connected to the second front beam 2.

[0068] The portion of the third reinforcing plate 8 disposed inside the installation space 5 can be set in a bent shape. For example, its cross-section along the second direction can be "L"-shaped, so that the third reinforcing plate 8 has a larger connection area with the first front crossmember 1. The shapes of the first front crossmember 1 and the third reinforcing plate 8 can be adapted to each other for easy connection between the two. The third reinforcing plate 8 extends along the first direction, and a part of it is located outside the installation space 5 and is connected to the second front crossmember 2. When the vehicle body structure is impacted, the third reinforcing plate 8 can transmit the impact force along the first direction, absorb energy, and improve the safety of the vehicle body structure.

[0069] The solution provided by the embodiment of the present application is provided with a second reinforcing plate 7, a third reinforcing plate 8, and a first reinforcing plate 6. Among them, the second reinforcing plate 7 and the third reinforcing plate 8 cooperate with each other to cover at least part of the areas of the first front crossmember 1 and the second front crossmember 2. Compared with the prior art in which a large number of reinforcing plates are provided, the solution of the embodiment of the present application simplifies the vehicle body structure, reduces the number of reinforcing plates, reduces the manufacturing process and processing difficulty, and improves the safety of the vehicle body structure. The heights of the second reinforcing plate 7 and the third reinforcing plate 8 are lower than those of the front crossmember sealing plate 3, which will not occupy the foot space inside the vehicle. Moreover, when the front crossmember sealing plate 3 and the front panel are coated and sealed, the second reinforcing plate 7 and the third reinforcing plate 8 will not block the coating area, and the coating operation is convenient and the sealing performance is good.

[0070] As Figure 1 and Figure 5 shown, in a possible implementation manner, the vehicle body structure includes a front floor crossmember 10. The front floor crossmember 10 is connected to the first front crossmember 1, and the position of the front floor crossmember 10 along the first direction corresponds to that of the second reinforcing plate 7.

[0071] The front floor crossmember 10 is connected to the second front crossmembers 2 located on both sides of the vehicle body structure along the second direction. The front floor crossmember 10 is used to transmit energy along the second direction when the vehicle body structure is impacted, so as to achieve a better overall energy absorption effect. The position where the second reinforcing plate 7 and the third reinforcing plate 8 are connected to each other corresponds to the position where the front floor crossmember 10 is connected to the second front crossmember 2 along the first direction. The impact received by the second reinforcing plate 7 and the third reinforcing plate 8 can also be better transmitted through the front floor crossmember 10, thereby improving the safety of the vehicle body structure.

[0072] As Figure 2 and Figure 5As shown, in a possible implementation, the vehicle body structure includes an inner sill panel 11, which is disposed outside the second front beam 2 along the second direction. The inner sill panel 11 extends along the first direction, and the second front beam 2 is connected to the inner sill panel 11, and can transmit energy through the inner sill panel 11. The position where the second reinforcement plate 7 is connected to the second front beam 2 is close to the inner sill panel 11. The impact energy can be transmitted to the inner sill panel 11 through the second reinforcement plate 7 to enhance the effect of dispersing the impact and improve the safety of the vehicle body structure.

[0073] As Figure 3 and Figure 5 shown, in a possible implementation, the vehicle body structure includes a rear extension plate 12 of the front beam and a front floor longitudinal beam 13. The rear extension plate 12 of the front beam is connected to the second front beam 2 along the first direction, and the front floor longitudinal beam 13 is connected to the rear extension plate 12 of the front beam along the first direction.

[0074] The front floor longitudinal beam 13 and the rear extension plate 12 of the front beam extend along the first direction, and can further transmit the energy transmitted from the second front beam 2. By adjusting the length of the rear extension plate 12 of the front beam, the position of the front floor longitudinal beam 13 connected thereto can be further adjusted, so as to more reasonably set the positional relationship of each component in the vehicle.

[0075] As Figure 4 shown, the vehicle body structure provided by the embodiments of the present application can be used in new energy vehicles, hybrid vehicles, etc. In order to implement the installation of the battery pack, the vehicle body structure provided by the embodiments of the present application is provided with a battery pack mounting plate 14 connected to the second front beam 2, so as to dispose the power battery pack 15 on the battery pack mounting plate 14. In addition, a battery pack longitudinal beam 16 is also provided. The battery pack longitudinal beam 16 is connected to the battery pack mounting plate 14, and the battery pack longitudinal beam 16 is disposed on the side wall of the battery pack mounting plate 14 along the second direction, and can play a role in supporting and protecting the power battery pack 15.

[0076] The embodiments of the present application provide a vehicle body structure, which includes a first front beam 1, a second front beam 2, a front beam sealing plate 3, a first reinforcement plate 6, and a front panel cross beam 4. The first front beam 1 and the second front beam 2 are sequentially arranged and connected to each other along the first direction, and the front beam sealing plate 3 is connected to the first front beam 1 and the second front beam 2 along the second direction. The front panel cross beam 4 is connected to the second front beam 2. There is an installation space 5 between the first front beam 1, the second front beam 2, and the front beam sealing plate 3. The first reinforcement plate 6 is located inside the installation space 5. The first reinforcement plate 6 is respectively connected to the first front beam 1, the second front beam 2, and the front beam sealing plate 3. The position of the first reinforcement plate 6 in the first direction corresponds to that of the front panel cross beam 4, and is used to enhance the ability of the vehicle body structure to transmit and absorb energy when being impacted, and improve the safety of the vehicle body structure.

[0077] The structure, features, and effects of the present application have been described in detail based on the embodiments shown in the drawings. The above is only the preferred embodiment of the present application, but the present application is not limited to the scope of implementation shown in the drawings.
