Abstract
Description
Technical Field
[0001] This disclosure relates to the field of vehicle technology, and more specifically, to a vehicle body structure and a vehicle. Background Technology
[0002] As vehicles continue to evolve, the market demands increasingly higher levels of vehicle safety. Among these demands is the vehicle's ability to protect occupants during a frontal collision, a crucial indicator of vehicle safety and a significant area of research in the automotive field. Utility Model Content
[0003] The purpose of this disclosure is to provide a vehicle body structure and vehicle that at least partially solves the technical problems existing in the related art.
[0004] To achieve the above objectives, according to a first aspect of this disclosure, a vehicle body structure is provided, including an A-pillar, a sill beam, a front longitudinal beam, and an external connection structure for the front longitudinal beam. The sill beam includes a main body and a protrusion. The lower end of the A-pillar is connected to the main body. The protrusion protrudes forward from the A-pillar. The external connection structure for the front longitudinal beam is located between the front longitudinal beam and the sill beam. One end of the external connection structure is connected to the front longitudinal beam, and the other end of the external connection structure is at least partially connected to the protrusion.
[0005] Optionally, the projection of the front longitudinal beam external connection structure in the front-rear direction is configured to at least partially coincide with the projection of the wheel in the front-rear direction.
[0006] Optionally, the front longitudinal beam external connection structure includes a first connector and a second connector located behind the first connector. One end of the first connector is connected to the front longitudinal beam, and the other end of the first connector is connected to the protrusion. One end of the second connector is connected to the front longitudinal beam, and the other end of the second connector is connected to the main body.
[0007] Optionally, the second connector is provided with a first battery pack mounting structure.
[0008] Optionally, the vehicle body structure further includes a central tunnel and a front longitudinal beam internal connection structure, wherein the front longitudinal beam internal connection structure is located between the central tunnel and the front longitudinal beam, one end of the front longitudinal beam internal connection structure is connected to the central tunnel, and the other end of the front longitudinal beam internal connection structure is connected to the front longitudinal beam.
[0009] Optionally, a second battery pack mounting structure is provided on the inner connecting structure of the front longitudinal beam.
[0010] Optionally, the vehicle body structure further includes a lifting bracket, which is at least partially disposed on the protrusion and is used to connect to the lifting mechanism.
[0011] Optionally, the protrusion includes an inner plate and an outer plate that interlock, and the lifting bracket is disposed on the inner plate.
[0012] Optionally, the length of the protrusion in the front-to-back direction is 40mm to 60mm.
[0013] Optionally, the front end face of the protrusion is located in front of the connection between the front longitudinal beam external connection structure and the protrusion.
[0014] Optionally, the distance between the front end face of the protrusion and the frontmost end of the connection between the external connecting structure of the front longitudinal beam and the protrusion is 20mm to 40mm.
[0015] According to a second aspect of this disclosure, a vehicle is provided, including the aforementioned body structure.
[0016] With the above technical solution, since the protrusion extends forward from the A-pillar, when the vehicle is subjected to a frontal collision, the protrusion can not only bear the collision force before the A-pillar, but also transmit the collision force it bears to the rear through the main body. This helps to prevent the A-pillar from deforming, and in turn helps to prevent the doors from not being able to open or the passenger compartment from deforming due to the deformation of the A-pillar, thus improving the safety of the vehicle.
[0017] Furthermore, the front longitudinal beam is at least partially connected to the protrusion through the external connection structure of the front longitudinal beam. This not only helps to improve the structural strength of the front longitudinal beam and the protrusion, but also allows the front longitudinal beam and the sill beam to transfer collision forces through the external connection structure of the front longitudinal beam. This helps to disperse the collision forces borne by the front longitudinal beam or the sill beam, and prevents the front longitudinal beam from deforming and intruding into the passenger compartment or compressing the space of the passenger compartment, thereby further improving the safety of the vehicle.
[0018] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation
[0025] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0026] In this disclosure, unless otherwise stated, directional terms such as "up," "down," "top," "bottom," "front," "rear," "left," and "right" are generally defined according to the vehicle's position in normal driving conditions. For example, the direction towards the vehicle's roof is "up" or "top," the direction towards the vehicle's chassis is "down" or "bottom," the direction towards the front of the vehicle is "front," the direction towards the rear of the vehicle is "rear," the direction towards the left wheel of the vehicle is "left," and the direction towards the right wheel of the vehicle is "right" (see reference for details). Figures 1-3 As shown, the X direction is the front-to-back direction, the Y direction is the left-to-right direction, and the Z direction is the up-to-down direction. The directional terms used are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientation construction and operation, and therefore should not be construed as a limitation of this disclosure. "Inner" and "outer" refer to the inner and outer contours of the corresponding components. In addition, the terms "first," "second," etc., used are to distinguish one element from another and do not have sequential or importance.
[0027] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.
[0028] like Figures 1 to 3 As shown, according to a first aspect of this disclosure, a vehicle body structure is provided, including an A-pillar 20, a sill beam 90, a front longitudinal beam 70, and a front longitudinal beam external connection structure 73. The sill beam 90 includes a main body 92 and a protrusion 91. The lower end of the A-pillar 20 is connected to the main body 92, and the protrusion 91 protrudes forward from the A-pillar 20. The front longitudinal beam external connection structure 73 is located between the front longitudinal beam 70 and the sill beam 90. One end of the front longitudinal beam external connection structure 73 is connected to the front longitudinal beam 70, and the other end of the front longitudinal beam external connection structure 73 is at least partially connected to the protrusion 91.
[0029] With the above technical solution, since the protrusion 91 protrudes forward from the A-pillar 20, when the vehicle is subjected to a frontal collision, the protrusion 91 can not only bear the collision force before the A-pillar 20, but also transmit the collision force it bears to the rear through the main body 92. This helps to prevent the A-pillar 20 from deforming, and further helps to prevent the door from being unable to open or the passenger compartment from deforming due to the deformation of the A-pillar 20, thereby improving the safety of the vehicle.
[0030] Furthermore, the front longitudinal beam 70 is at least partially connected to the protrusion 91 through the front longitudinal beam external connection structure 73. This not only helps to improve the structural strength of the front longitudinal beam 70 and the protrusion 91, but also allows the front longitudinal beam 70 and the sill beam 90 to transfer collision forces through the front longitudinal beam external connection structure 73. This helps to disperse the collision forces borne by the front longitudinal beam 70 or the sill beam 90, and prevents the front longitudinal beam 70 from deforming and intruding into the passenger compartment or compressing the space of the passenger compartment, thereby further improving the safety of the vehicle.
[0031] It should be noted that the protrusion 91 protruding forward from the A-pillar 20 mentioned above refers to the protrusion 91 protruding forward from the inner panel and / or outer panel of the A-pillar.
[0032] Optionally, the front longitudinal beam external connection structure 73 is configured to define a cavity with the front bulkhead 10, thereby enabling the front longitudinal beam external connection structure 73 to have good force transmission performance with a lighter weight.
[0033] Optionally, the front longitudinal beam 70 may include a main body section and a downwardly curved section connected to the main body section. The external connection structure 73 of the front longitudinal beam may be connected to the downwardly curved section (i.e., connected to the rear section of the front longitudinal beam 70), thereby strengthening the rear section of the front longitudinal beam 70 and enhancing the impact force dispersion effect on the rear section of the front longitudinal beam 70.
[0034] This disclosure does not limit the specific location of the front longitudinal beam external connection structure 73. As one embodiment, the projection of the front longitudinal beam external connection structure 73 in the front-rear direction is set to at least partially coincide with the projection of the wheel in the front-rear direction.
[0035] This design allows the front longitudinal beam external connection structure 73 to withstand the impact of the wheel and stop the wheel in the event of a small offset collision or when the wheel has a serious tendency to move backward, thereby reducing the deformation of the front bulkhead 10 and A-pillar 20 caused by the collision impact.
[0036] In addition, the front longitudinal beam external connection structure 73 can also transmit the impact force of the wheel to the rear through the sill beam 90, thereby dispersing the impact force and helping to prevent the front longitudinal beam external connection structure 73 from deforming and intruding into the front bulkhead 10.
[0037] As one implementation method, such as Figure 1 As shown, the front longitudinal beam external connection structure 73 includes a first connector 731 and a second connector 732 located behind the first connector 731. One end of the first connector 731 is connected to the front longitudinal beam 70, and the other end of the first connector 731 is connected to the protrusion 91. One end of the second connector 732 is connected to the front longitudinal beam 70, and the other end of the second connector 732 is connected to the main body 92.
[0038] With this configuration, the front longitudinal beam 70 can not only transmit the impact force it receives to the rear via the first connector 731 and the protrusion 91, but also via the second connector 732 and the main body 92. In other words, by setting up the first connector 731 and the second connector 732, the path for the front longitudinal beam 70 to transmit force to the rear can be increased, which is conducive to further dispersing the impact force borne by the front longitudinal beam 70, and thus further helps to prevent the front longitudinal beam 70 from deforming and intruding into the passenger compartment or compressing the space of the passenger compartment.
[0039] It is understood that the first connector 731 and the second connector 732 can be constructed as a single piece or as separate structures, and this disclosure does not limit this.
[0040] Optionally, such as Figure 1 and Figure 2 As shown, the second connector 732 is provided with a first battery pack mounting structure 733.
[0041] When installing the battery pack 200, the battery pack 200 can be installed on the second connector 732 through the first battery pack mounting structure 733. Since the second connector 732 is located in front of the floor panel and close to the front compartment area, setting the first battery pack mounting structure 733 on the second connector 732 helps to increase the arrangement space of the battery pack 200 in the front and rear directions, and allows the battery pack 200 to have a larger length dimension, so that the front end of the battery pack 200 can protrude forward from the floor panel, thereby increasing the driving range of the battery pack 200.
[0042] Optionally, such as Figure 3As shown, the vehicle body structure also includes a central tunnel 80 and a front longitudinal beam internal connection structure 74. The front longitudinal beam internal connection structure 74 is located between the central tunnel 80 and the front longitudinal beam 70. One end of the front longitudinal beam internal connection structure 74 is connected to the central tunnel 80, and the other end of the front longitudinal beam internal connection structure 74 is connected to the front longitudinal beam 70.
[0043] Since the front longitudinal beam 70 is connected to the central channel 80 through the front longitudinal beam internal connecting structure 74, this not only helps to improve the structural strength of the front longitudinal beam 70, but also allows the front longitudinal beam 70 to transfer the impact force it bears to the central channel 80 through the front longitudinal beam internal connecting structure 74. This helps to disperse the impact force borne by the front longitudinal beam 70, and thus helps to prevent the front longitudinal beam 70 from deforming and intruding into the front bulkhead 10.
[0044] Optionally, the front longitudinal beam internal connection structure 74 is configured to define a cavity with the front bulkhead 10 of the vehicle, thereby enabling the front longitudinal beam internal connection structure 74 to have good force transmission performance with a lighter weight.
[0045] Optionally, the internal connecting structure 74 of the front longitudinal beam can be connected to the downward bending section of the front longitudinal beam 70, that is, connected to the rear section of the front longitudinal beam 70, thereby strengthening the rear section of the front longitudinal beam 70 and enhancing the impact force dispersion effect on the rear section of the front longitudinal beam 70.
[0046] Optionally, such as Figure 1 and Figure 2 As shown, a second battery pack mounting structure 741 is provided on the inner connecting structure 74 of the front longitudinal beam.
[0047] When installing the battery pack 200, the battery pack 200 can be installed on the front longitudinal beam inner connection structure 74 via the second battery pack mounting structure 741. Since the front longitudinal beam inner connection structure 74 is located in front of the floor panel and close to the front compartment area, setting the second battery pack mounting structure 741 on the front longitudinal beam inner connection structure 74 helps to increase the arrangement space of the battery pack 200 in the front-rear direction and gives the battery pack 200 a larger length dimension, so that the front end of the battery pack 200 can protrude forward from the floor panel, thereby increasing the driving range of the battery pack 200.
[0048] Optionally, such as Figure 1 and Figure 2 As shown, the vehicle body structure also includes a lifting bracket 93, which is at least partially disposed on the protrusion 91 and is used to connect with the lifting mechanism.
[0049] Since the lifting bracket 93 can be connected to the lifting mechanism, it can serve as a connection point between the lifting mechanism and the vehicle body structure. This helps to prevent the vehicle body structure from being deformed by the lifting mechanism during the lifting process, and also helps to prevent the vehicle body structure from detaching from the lifting mechanism and causing an accident during the lifting process.
[0050] Furthermore, the lifting bracket 93 is at least partially located on the protrusion 91, which not only helps to make more room for the battery pack 200 in the front-rear direction and avoids interference between the lifting mechanism and the battery pack 200 when they are connected, but also improves the space utilization of the area where the sill beam 90 protrudes from the A-pillar 20.
[0051] In this disclosure, the lifting bracket 93 can be positioned at any suitable location on the protrusion 91; this disclosure does not limit this. As one embodiment, such as... Figure 1 As shown, the protrusion 91 includes an inner plate 911 and an outer plate 912 that are interlocked, and the lifting bracket 93 is disposed on the inner plate 911.
[0052] Since the inner plate 911 of the protrusion 91 is close to the inner side of the vehicle body structure, mounting the lift bracket 93 on the inner plate 911 will not affect the vehicle's appearance. In other embodiments, the lift bracket 93 may also be mounted on the outer plate 912.
[0053] This disclosure does not limit the length of the sill beam 90 protruding from the A-pillar 20 in the longitudinal direction. As one embodiment, the length of the protrusion 91 in the longitudinal direction is 40mm to 60mm. The protrusion 91 with this length can ensure that the sill beam 90 bears the impact force before the A-pillar 20 when the vehicle is subjected to a frontal collision, and the protrusion 91 is not so long as to affect other structures of the vehicle body. In addition, it can facilitate the connection of the protrusion 91 with other structures of the vehicle body, such as the front longitudinal beam external connection structure 73 mentioned above.
[0054] Optionally, such as Figure 1 As shown, the front end face of the protrusion 91 is located in front of the connection between the front longitudinal beam outer connecting structure 73 and the protrusion 91. Since the front end face of the protrusion 91 is located in front of the connection between the front longitudinal beam outer connecting structure 73 and the protrusion 91, when the vehicle is subjected to a frontal collision, the protrusion 91 can absorb the collision force before the front longitudinal beam outer connecting structure 73, and the collision force can be transmitted to the front longitudinal beam 70 through the front longitudinal beam outer connecting structure 73.
[0055] This disclosure does not limit the distance between the front end face of the protrusion 91 and the foremost point of the connection between the front longitudinal beam outer connecting structure 73 and the protrusion 91. As one embodiment, the distance between the front end face of the protrusion 91 and the foremost point of the connection between the front longitudinal beam outer connecting structure 73 and the protrusion 91 can be 20mm to 40mm. With this arrangement, when the vehicle is subjected to a frontal collision, it is beneficial to ensure that the sill beam 90 bears the collision force before the front longitudinal beam outer connecting structure 73, and to prevent the protrusion 91 from being too long and affecting other body structures.
[0056] According to a second aspect of this disclosure, a vehicle is provided, including the aforementioned body structure.

However, this disclosure is not limited to the specific details of the above embodiments.

[0058] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.
[0059] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
