[0038] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0039] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0040] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0041] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0042] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0043] like Figures 1 to 10 As shown, according to one aspect of the utility model, a vehicle body structure is provided, including: a battery pack mounting beam 1 and a connecting plate 2, the two battery pack mounting beams 1 are spaced apart in the width direction (X direction) of the vehicle, and the battery pack mounting beams 1 extend along the front and rear direction of the vehicle; the connecting plate 2 is located at the front ends of the two battery pack mounting beams 1, and in the height direction (Z direction) of the vehicle, an upwardly recessed recessed area 201 is formed on the connecting plate 2, and the recessed area 201 forms a part of the battery pack mounting cavity.

[0044] Specifically, in the present embodiment, the connecting plate 2 is arranged at the front end of the two battery pack mounting beams 1, and a recessed area 201 for accommodating the battery pack is formed, so that a partial area of ​​the battery pack can be adapted in the recessed area 201, and at the same time, the two side edges are fixed on the battery pack mounting beams 1. On the one hand, the stability of the battery pack assembly is improved, that is, the ends and sides of the battery pack are protected. On the other hand, the arrangement of the two battery pack mounting beams 1 can enhance the rigidity of the vehicle body structure. When the vehicle is subjected to a head-on collision, the force transmitted from the front side of the vehicle body structure is guided to the two battery pack mounting beams 1 through the connecting plate 2, and then transmitted to the rear side of the vehicle through the battery pack mounting beams 1, thereby dispersing the collision force, reducing the risk of the battery pack being squeezed by the collision, and improving the safety performance of the battery pack.

[0045] Alternatively, if Figure 1 to Figure 2 as well as Figure 4 As shown, in the height direction of the vehicle, the body structure is formed with a through-hole structure 3, so that when the battery pack is located in the battery pack installation cavity, at least a portion of the upper surface of the battery pack can form the floor of the body structure.

[0046] Specifically, in this embodiment, the through-hole structure is a hole on the vehicle body structure that can connect the upper and lower sides of the floor (there is no separate floor structure in this embodiment). When the battery pack is installed in the battery pack installation cavity, the upper surface of the battery pack is located at the position of the through-hole structure 3 to form the floor of the vehicle body structure, eliminating the traditional floor and improving the weight reduction effect of the vehicle body structure. In addition, the through-hole structure 3 can form a closed-loop force transmission structure to improve the safety of the entire vehicle in a collision.

[0047] Alternatively, if Figure 1 to Figure 2 as well as Figure 4 As shown, in the height direction of the vehicle, a downwardly protruding first boss 202 is formed on the connecting plate 2, and at least one front battery pack mounting point 203 is provided on the first boss 202, and the front battery pack mounting point 203 is used to fix the battery pack.

[0048] Specifically, in this embodiment, the setting of the first boss 202 provides a front-end mounting point for the battery pack, that is, by setting at least one front battery pack mounting point 203 on the first boss 202, the front end of the battery pack can be fixed on the connecting plate 2, thereby improving the dynamic stiffness of the battery pack. At the same time, the rear side of the battery mounting cavity can be fixed on the rear crossbeam, making the installation of the entire battery pack more stable. Among them, multiple front battery pack mounting points 203 can be arranged in a row along the width direction of the vehicle, and the shape of the recessed area 201 can also be designed according to actual needs. Usually, it can be adaptively designed according to the shape of the battery pack and the components located on the side of the battery pack accommodating cavity, and the present utility model does not limit this.

[0049] Furthermore, the first boss 202 protrudes downward, and the battery pack is arranged in a recessed area 201 that is recessed upward, so that an energy-absorbing cavity 204 is formed on the front side of the battery pack (i.e., the position of the first boss 202), which can absorb collision energy. Without adding vehicle body structural parts, a certain buffer is formed for the force transmitted by the vehicle in a head-on collision, thereby reducing the energy transmitted to the battery pack in a head-on collision condition.

[0050] Alternatively, if Figure 1 to Figure 2 as well as Figure 5 , Figure 6 As shown, the vehicle body structure further includes a front longitudinal beam 4 , which is connected to the connecting plate 2 , and at least a portion of the front longitudinal beam 4 is disposed on the front side of the connecting plate 2 .

[0051] Specifically, in this embodiment, the front longitudinal beam 4 is connected to the connecting plate 2, and at least a part of it is located on the front side of the connecting plate 2. On the one hand, the force of the head-on collision can be guided by the front longitudinal beam 4 to be transmitted longitudinally to the battery pack mounting beam 1 and laterally to the connecting plate 2. Then, the force is transmitted and absorbed through the guidance of the connecting plate 2 and the battery pack mounting beam 1, thereby avoiding squeezing of the battery pack and improving vehicle safety.

[0052] In actual applications, a central channel 11 can be set in the middle of the connecting plate 2 in the width direction of the vehicle, so that the force transmitted to the connecting plate 2 can be transmitted through the central channel 11, further dispersing the force of the head-on collision and improving the rigidity of the body structure and the safety of the vehicle.

[0053] Alternatively, if Figure 1 to Figure 2 as well as Figure 5 As shown, two front longitudinal beams 4 are provided, and the two front longitudinal beams 4 are spaced apart in the width direction of the vehicle; in the width direction of the vehicle, the connecting plate 2 is connected between the two front longitudinal beams 4 .

[0054] Specifically, in actual applications, two front longitudinal beams 4 are arranged at the two ends of the connecting plate 2, so that the force of a head-on collision can be transmitted to the connecting plate 2 through the front longitudinal beams 4 on both sides, increasing the force transmission path of the vehicle in the length direction (Y direction), absorbing and dispersing the collision force on the front side of the battery pack, and improving the vehicle body stiffness.

[0055] Alternatively, if Figure 1 to Figure 2 And pictures to Fig.10 As shown, the vehicle body structure also includes a rocker beam 5, the front longitudinal beam 4 is connected to the rocker beam 5, and a subframe mounting point 401 is provided on the front longitudinal beam 4. In the front and rear direction (Y direction) of the vehicle, the subframe mounting point 401 is provided on the extension line of the battery pack mounting beam 1.

[0056] Specifically, in this embodiment, the sill beam 5 can usually withstand the side impact force of the vehicle and form a longitudinal force transmission path for the front impact force of the vehicle to ensure the rigidity of the vehicle body structure. The subframe mounting point 401 is expanded outward to the extension direction of the battery pack mounting beam 1, so that the added battery pack mounting beam 1 can just add a force transmission path in the rear section of the front longitudinal beam 4, reducing the damage to the human body and the battery pack in the rear high-speed collision and the side column collision, and improving the safety of the whole vehicle.

[0057] Alternatively, if Figure 1 to Figure 2 as well as Figures 5 to 10 As shown, two threshold beams are provided. In the width direction of the vehicle, one battery pack mounting beam 1 is spaced apart from one threshold beam 5 , and the two threshold beams 5 are respectively located on the outer sides of the corresponding battery pack mounting beams 1 .

[0058] Specifically, in this embodiment, two battery pack mounting beams 1 are respectively arranged on the left and right sides of the vehicle body structure, and two door sill beams 5 are respectively arranged on the outside of the two battery pack mounting beams 1 in a one-to-one correspondence. The battery pack mounting beam 1 and the door sill beam 5 are arranged at intervals, so that in the side collision direction, the gap between the battery pack mounting beam 1 and the door sill beam 5 can form an energy absorption space 102, which absorbs energy for the side collision and further reduces the damage to the human body and the battery pack in the rear high-speed collision and the side column collision. In actual applications, the interval between the door sill beam 5 and the battery pack mounting beam 1 can be designed to be about 120 mm, which can be specifically designed according to the actual needs of the whole vehicle, and the present utility model does not limit this.

[0059] Alternatively, if Figure 1 to Figure 2 as well as Figure 3 As shown, the two battery pack mounting beams 1 are respectively connected to the corresponding door sill beams 5 via a connecting member 6, and a seat cross beam 7 is arranged between the two battery pack mounting beams 1. In the width direction of the vehicle, the connecting member 6 and the seat cross beam 7 are arranged opposite to each other.

[0060] Specifically, in this embodiment, two or three seat cross beams 7 can be provided to install and support the seats in the passenger compartment. The provision of the seat cross beam 7 enables it to form multiple U-shaped structures with the connecting plate 2 and the battery pack mounting beam 1, forming a closed-loop force transmission structure, so that the deformation area of ​​the body structure can avoid the battery pack area during a side collision, thereby improving the safety of the entire vehicle by avoiding the deformation area, and providing protection for the collision safety of the battery pack and the integration of the body structure and the battery. The connector 6 is provided at a position opposite to the seat cross beam 7, so that during a side collision, the cross beam can provide a certain buffering of the side collision force to the connector 6, further protecting the battery from being squeezed.

[0061] Optionally, in the height direction of the vehicle, a second boss 402 protruding downward is formed on the front longitudinal beam 4 , and at least a portion of the connecting plate 2 is connected to the second boss 402 .

[0062] Specifically, in this embodiment, the second boss 402 on the front longitudinal beam 4 is connected to at least a portion of the connecting plate 2, which is beneficial to the integrity of the vehicle body structure on the one hand, and is beneficial to the formation of a force transmission path of the vehicle body structure on the other hand, thereby improving the rigidity and integration of the vehicle body structure.

[0063] Optionally, the front end of the battery pack mounting beam 1 is connected to the second boss 402, and in the height direction of the vehicle, a downwardly protruding first boss 202 is also formed on the connecting plate 2, and the bottom surface of the first boss 202, the bottom surface of the second boss 402 and the bottom surface of the battery pack mounting beam 1 are all located on the same plane.

[0064] Specifically, in this embodiment, the battery pack mounting beam 1, the connecting plate 2 and the front longitudinal beam 4 are connected to each other, which is conducive to the integration of the vehicle body structure. At the same time, the lower surfaces of the battery pack mounting beam 1, the connecting plate 2 and the front longitudinal beam 4 are on the same plane, further improving the overall structural rigidity and strength of the three components.

[0065] Alternatively, if Figure 1 to Figure 2 as well as Figures 5 to 7 As shown, the vehicle body structure also includes a rear longitudinal beam 8, at least a portion of which is located at the rear side of the battery pack mounting beam 1, and in the height direction of the vehicle, a third boss 801 protruding downward is formed on the rear longitudinal beam 8; the rear end of the battery pack mounting beam 1 is connected to the third boss 801, and the bottom surface of the third boss 801 is located on the same plane as the bottom surface of the battery pack mounting beam 1.

[0066] Specifically, in this embodiment, the rear longitudinal beam 8 is arranged so that it can form a force transmission path with the battery pack mounting beam 1, which can absorb the collision force of frontal collision, side collision and rear collision, thereby improving the integration of the entire vehicle body structure. At the same time, the lower surfaces of the rear longitudinal beam 8 and the battery pack mounting beam 1 are in the same plane, further improving the overall structural rigidity.

[0067] Alternatively, if Figure 1 to Figure 2 As shown, the vehicle body structure further includes a sealing structure 9, at least a portion of which is arranged around the circumference of the through-hole structure 3, and when the battery pack is located in the battery pack installation cavity, the sealing structure 9 is suitable for being sealed and connected to the battery pack.

[0068] Specifically, in this embodiment, the sealing structure 9 is extended around the circumference of the through-hole structure 3, so that when the battery pack is assembled in the battery pack installation cavity, the sealing structure 9 can form a seal on the upper and lower sides of the battery pack to prevent sewage and debris at the bottom of the vehicle from entering the interior of the vehicle through the through-hole structure 3. In addition, the sealing plate can be arranged on the same plane as the recessed area 201 of the connecting plate 2, so that the battery pack installation cavity can extend along the length direction of the vehicle (the front of the vehicle), so as to realize the installation of a battery pack with a larger capacity.

[0069] Alternatively, if Figure 4 As shown, the vehicle body structure also includes a front longitudinal beam 4. In the height direction of the vehicle, the sealing structure 9 has a fourth boss 901 protruding upward; the connecting plate 2 and at least a portion of the front longitudinal beam 4 are stacked on the upper side of the sealing plate and extend to the front side of the fourth boss 901. The strength of the sealing plate is higher than that of the connecting plate 2.

[0070] Specifically, in this embodiment, a fourth boss 901 is designed on the sealing structure 9, which can improve the sealing performance of the sealing structure 9 on the one hand, and on the other hand, by arranging the connecting plate 2 and the front longitudinal beam 4 on the upper side of the sealing plate and making the strength of the sealing structure 9 higher than the connecting plate 2, the rear section of the connecting plate 2 and the rear section of the front longitudinal beam 4 can be guided to deform and invade above the battery pack, thereby protecting the battery pack.

[0071] Alternatively, if Figure 1 to Figure 2 as well as Figures 5 to 9 As shown, it also includes two rear longitudinal beams 8 spaced apart in the width direction of the vehicle and a rear cross beam 10 connected between the two rear longitudinal beams 8, and at least one rear battery pack mounting point 1001 is arranged on the rear cross beam 10. In the height direction of the vehicle, the rear battery pack mounting point 1001 and the front battery pack mounting point 203 are not on the same plane.

[0072] Specifically, in actual applications, the battery pack installation point will inevitably be subjected to shear force for the residual force transmitted from the front of the vehicle. According to the force and vector summation relationship, the shear force borne by the battery pack in this plane is maximum at this time, which may easily lead to problems such as the installation point falling off and breaking. Setting the front battery pack installation point 203 and the rear battery pack installation point 1001 on different planes can improve the stability of the battery pack installation.

[0073] Alternatively, if Figure 1 to Figure 2 as well as Fig. 9 As shown, the body structure also includes a plurality of seat cross beams 7, on which a plurality of first battery pack mounting points 701 are arranged, and on which a plurality of second battery pack mounting points 101 are arranged, and in the height direction of the vehicle, the first battery pack mounting point 701 is not on the same plane as the front battery pack mounting point 203 and / or the rear battery pack mounting point 1001.

[0074] Specifically, in this embodiment, the arrangement of the first battery pack mounting point 701 and the second battery pack mounting point 101 makes the installation of the battery pack more stable, and at the same time, the first battery pack mounting point 701 is not on the same plane as the front battery pack mounting point 203 and / or the rear battery pack mounting point 1001, which can further improve the safety of the battery pack.

[0075] Optionally, a seat cross beam 7 is further provided between the two battery pack mounting beams 1 , and in the height direction of the vehicle, the sealing structure 9 also extends to below the seat cross beam 7 and the rear cross beam 10 , so as to further improve the sealing performance of the sealing structure 9 .

[0076] According to the second aspect of the present invention, referring to Figures 1 to 10 , provides a vehicle, including the vehicle described in the first aspect, wherein at least a portion of the battery pack is located in the recessed area 201.

[0077] Specifically, the vehicle provided in this embodiment adopts the body structure provided in the first aspect, the battery pack is installed in the battery pack installation cavity, and at least a portion of the battery pack is located in the recessed area 201, which can prevent the battery pack from being squeezed and improve the safety of the vehicle.

[0078] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

[0079] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
