Description

Technical Field

[0001] The present application relates to the technical field of vehicle safety, and in particular to a vehicle body structure and a vehicle having the same. Background Art

[0002] This section only involves technical content related to this application, which is not necessarily disclosed prior art.

[0003] At present, with the popularization of vehicles, consumers are paying more and more attention to vehicle safety. At the same time, regulations and evaluation agencies have also put forward higher requirements for vehicle safety indicators. Specifically, one of the working conditions with higher requirements for vehicle safety is a small offset collision, which mainly refers to a collision with less than 25% overlap on one side of the width direction of the front of the vehicle. Under this collision condition, the traditional body relies on a single longitudinal beam and is difficult to effectively play the role of deformation and energy absorption. Instead, it uses the longitudinal beam to cooperate with the A-pillar, door sill and other structures to support the integrity of the passenger compartment.

[0004] However, new energy vehicles are becoming mainstream, and new energy vehicles are generally equipped with long-range battery packs, which will greatly increase the overall mass of the vehicle, resulting in a large initial kinetic energy for new energy vehicles in small offset collisions. The part where the longitudinal beam is connected to the A-pillar is easily torn, which may damage the integrity of the passenger compartment; in addition, since the small offset collision condition mainly involves the area near the tire, in a small offset collision, the movement state of the tire will directly affect the integrity of the passenger compartment. For example, a small offset collision occurs when the tire is moving straight or the rear side of the tire is tilted inward, which will greatly damage the integrity of the passenger compartment, causing harm to the occupants.

[0033] It should be noted that the term "and / or" in this application should be understood as follows:

[0034] First, the term "and / or" between the first subject and the second subject includes any one of the following meanings: (1) only the first subject; (2) only the second subject; and (3) the first subject and the second subject.

[0035] The specific embodiments of the vehicle body structure are mainly described below in conjunction with the drawings of the specification.

[0036] First, refer to Figure 1 The present application provides a vehicle body structure 100, which includes a vehicle body longitudinal beam 110, an A-pillar 120 and an A-pillar front support 130. The vehicle body longitudinal beam 110 and the A-pillar 120 overlap and form an overlapping portion, the A-pillar front support 130 covers and is connected to the overlapping portion, and the A-pillar front support 130, the vehicle body longitudinal beam 110 and the A-pillar 120 form a triangular support structure.

[0037] In the present application, the A-pillar front support 130 covers the overlapping portion connecting the body longitudinal beam 110 and the A-pillar 120, and the three form a triangular support structure, which increases the stiffness and strength of the connection portion between the body longitudinal beam 110 and the A-pillar 120, and the support force transmission effect is better. When a small offset collision occurs, the connection portion between the body longitudinal beam 110 and the A-pillar 120 is not easily torn, thereby reducing the risk of the passenger compartment being invaded, and trying to ensure the integrity of the passenger compartment and the personal safety of the occupants.

[0038] In some embodiments, reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The vehicle body structure 100 further includes a sill beam 140, which is overlapped with the A-pillar 120; the A-pillar front support 130, the A-pillar 120 and the sill beam 140 constitute a first force transmission path, and the vehicle body longitudinal beam 110, the A-pillar 120 and the sill beam 140 constitute a second force transmission path.

[0039] This embodiment utilizes the first force transmission path and the second force transmission path to disperse the force, wherein the setting of the A-pillar front support 130 is equivalent to extending the door sill beam 140 forward, so that when the vehicle is in a small offset collision, the door sill beam 140 can be subjected to force as early as possible, so as to transfer and disperse the impact energy to the rear of the vehicle body as quickly as possible, thereby reducing damage to the integrity of the passenger compartment and reducing injuries to passengers.

[0040] Furthermore, when a small offset collision occurs, if the tire at the front of the vehicle is in a straight-moving state, the rear side of the tire will directly contact the front face of the A-pillar front support 130, thereby transmitting and sharing the impact force through the first force transmission path; if the tire is in a state where the rear side is tilted outward, a portion of the rear side of the tire will contact the A-pillar front support 130, thereby being able to transmit part of the impact force through the first force transmission path. In this case, the tire generally flies outward, releasing major kinetic energy, and causing less damage to the integrity of the passenger compartment; if the tire is in a state where the rear side is tilted inward, the tire will mainly contact the body longitudinal beam 110 and transmit the impact force to the rear of the body through the second force transmission path, so as to reduce damage to the integrity of the passenger compartment and reduce injury to passengers.

[0041] In summary, when a small offset collision occurs, regardless of the movement state of the tires at the front of the vehicle and the structures connected thereto, the body structure 100 of the present application can effectively ensure the integrity of the passenger compartment and minimize damage to passengers.

[0042] It should be noted that, in the related art, the impact of small offset collisions of the vehicle is generally reduced through the chassis and the swing arm. The present application adopts the above-mentioned embodiment to replace the solution in the related art, thereby reducing the vehicle's restrictions on structures such as the chassis and the swing arm, and can save the cost of chassis development.

[0043] In particular, a small offset collision of the vehicle may occur on either side of the front of the vehicle. The drawings of the present application only show the structure on the left side of the vehicle body, and the structure on the right side of the vehicle body is symmetrical with the left side structure.

[0044] In some embodiments, reference Figures 2 to 4 , focus on Figure 3 The door sill beam 140 is provided with a battery mounting portion e, and the battery mounting portion e is used to install the power battery; the body structure 100 also includes a force transmission member 150 under the door sill, and the force transmission member 150 under the door sill is connected to the A-pillar 120 and / or the door sill beam 140, and the force transmission member 150 under the door sill and the battery mounting portion e are arranged correspondingly along the front and rear direction; the force transmission member 150 under the door sill, the power battery and the door sill beam 140 constitute a third force transmission path.

[0045] In this embodiment, when a small offset collision occurs, the rear side of the tire will also press against the force transmission member 150 under the door sill, thereby transmitting and sharing the impact force of the tire to the rear of the vehicle body through the third force transmission path, so as to further reduce the damage to the integrity of the passenger compartment caused by the small offset collision of the vehicle.

[0046] It should be noted that a battery frame is provided outside the power battery, and the force transmission member 150 under the door sill presses against the battery frame to transmit force, so the power battery will not be squeezed and damaged.

[0047] In particular, “and / or” in this embodiment indicates that the force transmission member 150 under the sill is completely disposed on the A-pillar 120 or the sill beam 140 , or a part of the structure is connected to the A-pillar 120 , and the other part is connected to the sill beam 140 .

[0048] In some embodiments, reference Figure 3 There is a battery assembly avoidance gap a between the force transmission member 150 under the door sill and the battery mounting portion e; the force transmission member 150 under the door sill can be squeezed by the tire to approach the battery mounting portion e and fill the battery assembly avoidance gap a.

[0049] Furthermore, a battery assembly avoidance gap a is provided between the force transmission member 150 under the threshold and the battery installation portion e, so as to avoid interference or collision between the power battery and the force transmission member 150 under the threshold when the power battery is installed on the threshold beam 140, thereby affecting the installation.

[0050] In particular, when the vehicle is involved in a small offset collision, the force transmission member 150 under the door sill will move toward the battery mounting portion e under the pressure of the tire until it presses against the battery frame of the power battery, thereby achieving the effect of compensating for the battery assembly avoidance gap a.

[0051] In some embodiments, the vehicle body longitudinal beam 110 includes a longitudinal beam front plate 111 and a longitudinal beam rear plate 112 connected front and rear; the longitudinal beam front plate 111 has a first energy absorption cavity b1, and the longitudinal beam rear plate 112 has a second energy absorption cavity b2 and a third energy absorption cavity b3 that are bifurcated, and the first energy absorption cavity b1, the second energy absorption cavity b2 and the third energy absorption cavity b3 constitute a "Y"-shaped energy absorption structure.

[0052] In this embodiment, when a small offset collision occurs with the rear side of the tire tilted inward, the "Y"-shaped energy absorption structure of the vehicle body longitudinal beam 110 will absorb part of the impact energy, and the remaining energy will be transmitted to the rear of the vehicle body through the second force transmission path, thereby reducing the impact effect.

[0053] In addition, the vehicle body structure 100 further includes a connecting plate 180 and a vehicle body panel 170. The connecting plate 180 is connected between the vehicle body longitudinal beam 110 and the door sill beam 140, further increasing the rigidity and strength of the supporting structure. The vehicle body panel 170 is distributed along the left-right direction and connects the vehicle body longitudinal beam 110 and the A-pillar 120 on the left and right sides of the vehicle body, and can also play a role in transmitting part of the impact force.

[0054] In some embodiments, reference Figure 1 and Figure 2 The vehicle body structure 100 further includes a roof beam 160, which is overlapped with the A-pillar 120; the A-pillar front support 130, the A-pillar 120 and the roof beam 160 constitute a fourth force transmission path, and the vehicle body longitudinal beam 110, the A-pillar 120 and the roof beam 160 constitute a fifth force transmission path.

[0055] With reference to the description of the first force transmission path and the second force transmission path, the fourth force transmission path and the fifth force transmission path can also achieve the effect of dispersing force to the rear of the vehicle body, wherein the roof beam 160 and the door sill beam 140 respectively constitute two upper and lower force transmission structures, thereby minimizing the damage to the integrity of the passenger compartment caused by the different movement states of the front tires of the vehicle.

[0056] In some embodiments, the A-pillar 120 includes an upper A-pillar 121 and a lower A-pillar 122 , the upper A-pillar 121 is connected between the lower A-pillar 122 and the roof beam 160 , and a deformation energy absorption portion f is provided at the connection between the upper A-pillar 121 and the lower A-pillar 122 and / or the upper A-pillar 121 and the roof beam 160 .

[0057] In this embodiment, when the lower A-pillar 122 is subjected to force and transmitted to the upper A-pillar 121, the deformation energy-absorbing portion f of the upper A-pillar 121 will deform and absorb part of the kinetic energy, and the remaining impact force will be transmitted to the rear of the vehicle body through the roof beam 160, thereby further reducing the damage to the integrity of the passenger compartment and reducing the harm to passengers.

[0058] In this embodiment, “and / or” means that the connection between the upper A-pillar 121 and the lower A-pillar 122 , or the connection between the upper A-pillar 121 and the roof beam 160 , or both of the above connections are provided with a deformation energy absorbing portion f.

[0059] In some embodiments, the A-pillar 120 has an A-pillar cavity c therein, and a plurality of A-pillar reinforcements 123 are disposed in the A-pillar cavity c.

[0060] Reference Figure 4 and Figure 5 The lower A-pillar 122 includes an A-pillar inner panel 1221 and an A-pillar outer panel 1222, which are interlocked with each other to form an A-pillar cavity c; a plurality of A-pillar reinforcements 123 are arranged in the A-pillar cavity c at intervals along the up-down direction, and the A-pillar reinforcements 123 are distributed along the front-to-back direction, and both ends of the A-pillar reinforcements 123 are connected to the inner wall of the A-pillar cavity c.

[0061] It should be noted that, for the convenience of observation, Figure 5 The A-pillar outer panel 1222 is removed, leaving only the A-pillar inner panel 1221 , thereby exposing a plurality of A-pillar reinforcements 123 inside the A-pillar cavity c.

[0062] Furthermore, the A-pillar cavity c can reduce weight, and the multiple A-pillar reinforcements 123 improve the structural rigidity of the lower A-pillar 122, which can transmit force to the rear of the vehicle body more quickly and reduce the degree of deformation caused by force. In addition, the A-pillar inner plate 1221 and the A-pillar outer plate 1222 are welded by flanging, and the A-pillar reinforcements 123 can reduce the tearing of welds caused by collision and extrusion.

[0063] In some embodiments, reference Figure 6 The sill beam 140 has a sill cavity d inside, and a plurality of sill reinforcement members 141 are disposed in the sill cavity d.

[0064] Specifically, a plurality of cross-partition plates 142 are provided in the sill cavity d, and the sill cavity d is divided into a plurality of chambers, at least some of which are lined with sill reinforcements 141; the sill cavity d has a weight reduction effect, and the partition plates 142 and the sill reinforcements 141 are used to enhance the structural rigidity of the sill beam 140, which can transmit force to the rear of the vehicle body more quickly and avoid deformation due to force, which would affect the integrity of the passenger compartment.

[0065] In a second aspect, the present application further provides a vehicle, which includes the vehicle body structure 100 in the first aspect.

[0066] The vehicle in the second aspect includes the vehicle body structure 100 in the first aspect. Therefore, the vehicle in the second aspect has at least all the technical effects of the vehicle body structure 100 in the first aspect, and the specific technical effects are not repeated here.

[0067] In addition, the embodiments in the present application only illustrate the body structure 100 and the structures in the vehicle related to the improvement points of the present application, and do not mean that the body structure 100 and the vehicle in the present application do not have other structures. For example, the vehicle also includes a chassis assembly, a suspension system, etc., and other structures are not described one by one here.

[0068] Although the embodiments of the present application are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations are all within the scope defined by the appended claims.
