Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a vehicle body structure and a vehicle. Background Technology

[0002] The vehicle body structure typically includes a front floor, sill beams, and two seat crossbeams. The sill beams are the main load-bearing structures on the side of the vehicle body. The inner sill plates in the sill beams are located on both sides of the front floor and are welded to the front floor. The two seat crossbeams are arranged sequentially above the front floor along the length of the vehicle body, and each seat crossbeam is independently connected to the inner sill plate.

[0003] In practical applications, if the inner door sill plate is subjected to the force of a side pillar collision, the inner door sill plate directly transmits the force to the corresponding seat crossbeam. The transmission path is relatively simple, resulting in poor collision avoidance capability of the vehicle. Utility Model Content

[0004] In view of this, the present application provides a vehicle body structure and a vehicle to solve the problem that the force transmission path of the existing vehicle body structure is relatively simple when it is subjected to a side pole collision, resulting in poor collision avoidance capability of the vehicle.

[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0006] In a first aspect, embodiments of this application provide a vehicle body structure, including:

[0007] Inner door sill panel;

[0008] The reinforcing member is connected to the inner sill plate;

[0009] At least two seat crossbeams, the extension direction of which intersects the extension direction of the inner sill plate, and the end of the seat crossbeam is connected to the inner sill plate. At least two seat crossbeams are arranged sequentially at intervals along the extension direction of the inner sill plate.

[0010] The reinforcing member is located between two adjacent seat crossbeams and is in contact with the two adjacent seat crossbeams.

[0011] In one possible implementation of this application, adjacent sides of two adjacent seat crossbeams contact the reinforcement.

[0013] In one possible implementation of this application, the first flange is located below the seat crossbeam, directly below the seat crossbeam, and from the end of the inner sill plate to the seat crossbeam adjacent to the end of the inner sill plate. A second sealant layer is provided between the side of the first flange away from the seat crossbeam and the inner sill plate.

[0014] In one possible implementation of this application, the reinforcing member is located below the first flange, directly above the reinforcing member, and from the end of the inner sill plate to the seat crossbeam adjacent to the end of the inner sill plate, and a third sealing layer is provided between the side of the first flange facing the seat crossbeam and the inner sill plate.

[0015] In one possible implementation of this application, a battery pack mounting beam is further included, which is located below and connected to the front floor. The reinforcing member is located between the battery pack mounting beam and the inner sill plate, and is connected to both the battery pack mounting beam and the front floor.

[0016] In one possible implementation of this application, the reinforcing member includes a connecting plate and two second flanges. Along the extending direction of the inner sill plate, the connecting plate is bent to form a recess and / or a protrusion.

[0017] In one possible implementation of this application, the connecting plate is provided with two recesses and one protrusion, the two recesses are located on both sides of the protrusion, and the second flange is connected to the side of the recesses opposite to the protrusion.

[0018] In one possible implementation of this application, a third flange is provided at the end of the recessed portion and / or the protruding portion adjacent to the inner sill plate, and a fourth flange is provided at the side of the second flange adjacent to the inner sill plate.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0033] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0034] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0035] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0036] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0037] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0038] This application provides a vehicle, which can be an electric vehicle or a hybrid vehicle, with a battery pack installed on the vehicle's body structure, which can power the vehicle's functions.

[0039] like Figure 1 As shown, the vehicle's body structure includes an inner panel 10, a front seat crossbeam 20, a rear seat crossbeam 30, and... Figure 1 The front floor (not shown) is connected to the inner panel 10. A mounting beam for mounting the battery pack is fixed below the front floor. The front seat beam 20 and the rear seat beam 30 are located above the front floor and are connected to the inner panel 10.

[0040] The inner panel 10 is part of the sill beam, which usually also includes an outer panel. The sill beam can enhance the rigidity of the vehicle body, resist side impacts, and protect the battery pack at the bottom, preventing the battery pack from deforming or short-circuiting due to side impacts.

[0041] In practical applications, if the inner panel 10 is subjected to the force of a side pillar collision, the inner panel 10 directly transmits the force to the seat crossbeam in the corresponding area. The transmission path is relatively simple, resulting in poor collision avoidance capability of the vehicle.

[0042] A common approach to this is as follows: Figure 1 As shown, a door sill inner panel reinforcement 40 is installed below the front seat crossbeam 20 and the rear seat crossbeam 30. The door sill inner panel reinforcement 40 connects the inner panel 10 and the front seat crossbeam 20, and the inner panel 10 and the rear seat crossbeam 30. Although adding the door sill inner panel reinforcement 40 can effectively absorb energy and reduce cell deformation during the side pole impact test in the China Insurance Research Institute (C-IASI) crash test, the front seat crossbeam 20 and the corresponding door sill inner panel reinforcement 40, and the rear seat crossbeam 20 and the corresponding door sill inner panel reinforcement 40 are vertically aligned and located on the upper and lower sides of the front floor. This means that only one layer of welding sealant can be applied at the connection between the inner panel 10 and the front floor. Due to manufacturing precision errors in the flanged surface connecting the front floor and the inner panel 10, there is a high probability of deformation between them during transportation. This greatly increases the risk of failure of the welding sealant at the flanged surface of the front floor and the inner panel 10 in traditional models, making the passenger compartment susceptible to external noise and environmental interference, affecting the quietness and comfort of the passenger compartment.

[0043] The vehicle body structure provided in this application embodiment includes an inner sill plate and at least two seat crossbeams connected to the inner sill plate. The at least two seat crossbeams are arranged sequentially at intervals along the extension direction of the inner sill plate. A reinforcing member is provided on the inner sill plate between two adjacent seat crossbeams, and the reinforcing member is in contact with both adjacent seat crossbeams. When subjected to a large side pole impact force, the reinforcing member can disperse the impact force to the two seat crossbeams, forming a one-to-two rigid force transmission structure, thereby effectively absorbing and transmitting the side pole impact force and improving the vehicle's collision avoidance capability.

[0044] Meanwhile, the reinforcement is located on the side of the seat crossbeam, which also means that the connection between the front floor and the inner door sill is not completely covered. This allows for the addition of an extra layer of adhesive between the front floor and the inner door sill to seal the connection, reducing the probability of seal failure between the front floor and the inner door sill.

[0045] Based on this, refer to Figure 2 and Figure 3 As shown, this application embodiment provides a vehicle body structure, including a door sill inner panel 100, a reinforcing member 200, and at least two seat crossbeams 300.

[0046] The extension direction of the sill inner panel 100 is the same as the length direction of the vehicle body. It can be understood that the number of sill inner panels 100 can be adjusted according to actual needs, and there can be one or more. For example, there are two sill inner panels 100, which are arranged opposite each other.

[0047] Each sill inner plate 100 is provided with at least one reinforcing member 200. For example, when two sill inner plates 100 are provided opposite to each other, the reinforcing member 200 is located on the adjacent side of the two sill inner plates 100 and is fixedly connected to the sill inner plates 100 by common methods such as welding.

[0048] The extension direction of the seat beam 300 intersects with the extension direction of the sill inner panel 100, for example, it is perpendicular to the extension direction of the sill inner panel 100. The end of the seat beam 300 is connected to the sill inner panel 100. For example, when two sill inner panels 100 are arranged opposite each other, the two ends of the seat beam 300 are respectively connected to the two sill inner panels 100.

[0049] In the event of a collision, the seat crossbeams 300 can absorb and disperse the impact force, protecting the safety of passengers. Simultaneously, at least two seat crossbeams 300 are spaced apart along the length of the vehicle body, allowing the seat to be supported and secured, ensuring its stability during vehicle movement.

[0050] The reinforcing member 200 is located between two adjacent seat crossbeams 300 and contacts the two seat crossbeams 300. That is, the reinforcing member 200 does not need to be directly fixed to the seat crossbeams 300, but it will at least partially contact the two seat crossbeams 300.

[0051] Specifically, there can be two or more seat crossbeams 300, and a reinforcing member 200 is provided between two adjacent seat crossbeams 300. The side impact force is distributed to different seat crossbeams 300 through the reinforcing member 200.

[0052] The reinforcement 200 is connected to the inner sill plate 100. When the inner sill plate 100 is subjected to a large side pole impact force, the reinforcement 200 can disperse the impact force to the two seat crossbeams 300 adjacent to the reinforcement. Through the connection point with the inner sill plate 100 and the contact point with the two seat crossbeams 300, a one-to-two rigid force transmission structure is formed, increasing the transmission path, thereby effectively absorbing and transmitting the side pole impact force and improving the vehicle's collision avoidance capability.

[0053] In some embodiments of this application, the adjacent side of two adjacent seat crossbeams 300 contacts the reinforcing member 200, that is, the reinforcing member 200 does not extend above or below the seat crossbeam 300, and does not obstruct the space above or below the seat crossbeam 300.

[0054] Meanwhile, the reinforcing member 200 directly contacts the side wall of the two adjacent seat beams 300 on the side close to the reinforcing member 200, which facilitates the transmission of force when the inner sill plate 100 is subjected to a large side column impact force.

[0055] It should be noted that the reinforcing member 200 can also contact other parts of the seat crossbeam 300, as long as the force can be effectively transmitted.

[0056] For example, the reinforcement 200 may partially contact the side of the seat crossbeam 300, partially extend above the seat crossbeam 300, and contact the top of the seat crossbeam 300.

[0057] For example, the reinforcement 200 may extend partially below the seat crossbeam 300, contacting the bottom of the seat crossbeam 300 and partially contacting the side of the seat crossbeam 300.

[0058] Furthermore, in some embodiments of this application, reference is made to... Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the vehicle body structure also includes a front floor 400. A first flange 440 is provided on the side of the front floor 400 adjacent to the inner door sill panel 100. Typically, the entire side of the front floor 400 is provided with the first flange 440. The first flange 440 extends upward toward the front floor 400 and is welded to the inner door sill panel 100. A first sealant layer 410 is provided at the weld between the first flange 440 and the inner door sill panel 100.

[0059] Specifically, the main body of the front floor 400 is located at the bottom of the vehicle. For example, when two sill inner panels 100 are provided, the front floor 400 is located between the two sill inner panels 100, and the first flange 440 is located on the side adjacent to the front floor 400 and the sill inner panel 100. The first flange 440 extends towards the top of the vehicle relative to the main body of the front floor 400. The first flange 440 and the sill inner panel 100 are fitted together on the side facing the front floor 400. The first flange 440 and the sill inner panel 100 can be connected by welding, and a first sealant layer 410 is added at the weld to seal the weld joint. The first sealant layer 410 can improve the sealing performance of the connection area between the front floor 400 and the sill inner panel 100, preventing water, dust, air and other substances from entering the vehicle body and reducing the impact of the external environment on the vehicle body interior.

[0060] The first sealant layer 410 can be a common sealant such as polyurethane sealant, epoxy resin sealant, butyl rubber sealant, or polyvinyl chloride sealant. After welding the first flange 440 and the inner sill plate 100, the sealant can be evenly applied to the welded joint using special equipment (such as a spray gun, extruder, or manual tool) and then cured to form the first sealant layer 410.

[0061] Furthermore, referring to Figure 5 , Figure 6 and Figure 7 As shown, the first flange 440 is located below the seat crossbeam 300, and the reinforcement 200 is located below the front floor 400, that is, below the first flange 440, directly below the seat crossbeam 300, and from the end of the inner door sill plate 100 to the seat crossbeam 300 adjacent to the end of the inner door sill plate 100 (the area between the outermost seat crossbeam 300 and the end of the inner door sill plate 100). A second sealant layer 420 is provided between the side of the first flange 440 away from the seat crossbeam 300 and the inner door sill plate 100.

[0062] Specifically, the first flange 440 is located below the seat crossbeam 300, and the reinforcement 200 is placed between the two seat crossbeams 300. At this time, the reinforcement 200 will not cover the area below the seat crossbeam 300. Therefore, sealant can be applied from below the first flange 440 to form a second sealant layer 420. The second sealant layer 420 is not only located directly below the seat crossbeam 300, but also in other areas of the first flange 440 that are offset from the reinforcement 200. The second sealant layer 420 can seal the gap between the bottom of the first flange 440 and the inner sill plate 100. The first sealant layer 410 can form a first sealing structure that isolates the passenger compartment inside the vehicle from the outside world, and the second sealant layer 420 can form a second sealing structure that isolates the passenger compartment inside the vehicle from the outside world. Thus, the sealing performance between the first flange 440 and the inner sill plate 100 is further improved through the second sealant layer 420, thereby improving the comfort of the vehicle.

[0063] Furthermore, referring to Figure 4 and Figure 7 As shown, a third sealant layer 430 is provided between the first flange 440 and the seat beam 300 (the area between the end of the sill inner panel 100 and the outermost seat beam) directly above the reinforcing member 200 and the sill inner panel 100, from the end of the sill inner panel 100 to the seat beam 300 adjacent to the end of the sill inner panel 100.

[0064] Specifically, the reinforcing member 200 and the seat crossbeam 300 do not overlap vertically, and the first flange 440 is located below the seat crossbeam 300. The reinforcing member 200 is located below the first flange 440. Therefore, in areas outside the seat crossbeam 300, the top of the connection area between the first flange 440 and the inner sill plate 100 is unobstructed, allowing sealant to be applied from above the reinforcing member 200 to form a third sealant layer 430. Furthermore, the third sealant layer 430 is not only located directly above the reinforcing member 200 but also in other areas offset from the seat crossbeam 300. The three sealing layers 430 can seal the gap between the top of the first flange 440 and the inner sill plate 100. The first sealing layer 410 can form a first sealing structure that isolates the passenger compartment inside the vehicle from the outside. The second sealing layer 420 can form a second sealing structure that isolates the passenger compartment inside the vehicle from the outside. The third sealing layer 430 can form a third sealing structure that isolates the passenger compartment inside the vehicle from the outside. Thus, the sealing performance between the first flange 440 and the inner sill plate 100 is further improved by the third sealing layer 430, thereby improving the comfort of the vehicle.

[0065] It should be noted that the second sealant layer 420 and the third sealant layer 430 can be formed using a sealant similar to the first sealant layer 410, or other types of sealant can be used, as long as they can effectively seal the gap between the first flange 440 and the inner sill plate 100.

[0066] In some embodiments of this application, reference is made to Figure 3 , Figure 7 and Figure 8 As shown, the reinforcing member 200 includes a connecting plate 210 and two second flanges 220. Along the extending direction of the inner sill plate 100, the connecting plate 210 is bent to form a recess 211 and / or a protrusion 212. The two second flanges 220 are respectively disposed at both ends of the connecting plate 210, and the two second flanges 220 are in corresponding contact with the seat crossbeam 300 adjacent to the second flanges 220.

[0067] Specifically, the reinforcing member 200 can be a single metal sheet. Second flanges 220 are formed on both sides of the connecting plate 210 by stamping, and recesses 211 and / or protrusions 212 are formed on the connecting plate 210. The edges of the recesses 211 and / or protrusions 212 are welded to the inner sill plate 100, which can increase the welding length between the reinforcing member 200 and the inner sill plate 100, thereby effectively improving the connection stability between the reinforcing member 200 and the inner sill plate 100 and enhancing the force transmission effect.

[0068] The second flange 220 can partially or completely contact the side of the seat crossbeam 300, and the side impact force can be transmitted to the seat crossbeam 300 through the second flange 220.

[0069] The recessed portion 211 extends downward toward the vehicle, while the protruding portion 212 extends upward toward the top of the vehicle. In addition, the seat crossbeam 300 is located above the front floor 400, while the reinforcing member 200 is located below the front floor 400. Therefore, the second flange 220 extends in the same direction as the protruding portion 212. In the design, a clearance space can be provided in the corresponding area of ​​the front floor 400 so that the second flange 220 can pass through the clearance space to contact the seat crossbeam 300, or the upper side protrusion of the seat crossbeam 300 can pass through the clearance space to contact the second flange 220.

[0070] Furthermore, the connecting plate 210 is provided with two recesses 211 and one protrusion 212. The two recesses 211 are respectively located on both sides of the protrusion 212. The recesses 211 and the protrusion 212 can be directly connected or separated by a certain distance. The second flange 220 is connected to the side of the recesses 211 away from the protrusion 212, so that the reinforcing member 200 forms an M-shaped structure.

[0071] This structure not only effectively increases the welding strength between the inner sill plate 100 and the reinforcing member 200, but also helps to improve the strength of the reinforcing member 200 and enhance the force transmission effect.

[0072] It should be noted that the arrangement of the recessed portion 211 and the raised portion 212 can be selected according to the space available for the reinforcement 200 to be installed in the vehicle body structure. For example, when the space is large, multiple recessed portions 211 and raised portions 212 can be arranged alternately in sequence, and a second flange 220 can be provided on the recessed portion 211 or raised portion 212 at the edge. When the space is small, only one raised portion 212 or recessed portion 211 can be provided. The specific arrangement can be adjusted according to the actual situation.

[0073] Furthermore, a third flange 2111 is provided at the end of the recessed portion 211 and / or the protruding portion 212 adjacent to the inner sill plate 100, and a fourth flange 221 is provided at the side of the second flange 220 adjacent to the inner sill plate 100. Both the fourth flange 221 and the third flange 2111 are attached to and connected to the inner sill plate 100.

[0074] Specifically, the third flange 2111 and the fourth flange 221 are both parallel to the inner surface of the corresponding area of ​​the inner sill plate 100, and can be fitted to the inner surface of the inner sill plate 100 and welded to the inner sill plate 100, thereby effectively connecting the reinforcing member 200 and the inner sill plate 100.

[0075] For example, the third flange 2111 can extend in a direction away from the front floor 400 to avoid interference with the first flange 440, while the fourth flange 221 can extend in a direction away from the connecting plate 210, which can further extend the welding length between the reinforcing member 200 and the inner sill plate 100 and improve the connection strength between the two.

[0076] Furthermore, the vehicle body structure also includes a battery pack mounting beam 500, which supports the battery pack. The extension direction of the battery pack mounting beam 500 is the same as the extension direction of the sill inner panel 100, that is, both extend along the length of the vehicle. The battery pack mounting beam 500 is located below the front floor 400 and connected to the front floor 400. The reinforcement 200 is located between the battery pack mounting beam 500 and the sill inner panel 100, and the reinforcement 200 is connected to both the battery pack mounting beam 500 and the front floor 400.

[0077] By connecting the reinforcing member 200 with the battery pack mounting beam 500 and the front floor 400, the force exerted by the reinforcing member 200 is further distributed to the battery pack mounting beam 500 and the front floor 400, so that the battery pack mounting beam 500 and the front floor 400 can simultaneously bear the force transmitted from the side pole collision, further improving the vehicle's collision avoidance capability.

[0078] For example, a fifth flange 222 can be added to the top of the second flange 220. The fifth flange 222 is attached to the bottom of the front floor 400 and connected, for example, by welding. This improves the connection stability between the reinforcement 200 and the front floor 400, so that when the reinforcement 200 is impacted, the force can be distributed to the front floor 400, further improving the collision protection capability of the vehicle body structure.

[0079] For example, a sixth flange 223 can be added to the side of the second flange 220 away from the inner sill plate 100. The sixth flange 223 is attached to and connected to the battery pack mounting beam 500, for example by welding, thereby improving the connection stability between the reinforcing member 200 and the battery pack mounting beam 500. When the reinforcing member 200 is impacted, the force can be dispersed to the battery pack mounting beam 500, further improving the collision protection capability of the vehicle body structure.

[0080] Furthermore, this application embodiment also provides a vehicle, which includes the body structure described in the above embodiments.
