Description

Technical Field

[0001] This application relates to the field of vehicle component manufacturing technology, and in particular to an A-pillar assembly, a body-in-white, and a vehicle. Background Technology

[0002] The A-pillars are the pillars on either side of the windshield of a vehicle, connecting to the left and right sides of the body to form the supporting structure at the front of the vehicle. As part of the body structure, the A-pillars, along with the B-pillars and C-pillars, bear the important responsibility of supporting the body and maintaining vehicle stability. In the event of a collision, the A-pillars can absorb and disperse some of the impact force, providing additional protection for the occupants.

[0003] As people pay more attention to vehicle safety, the requirements for vehicle collision performance are becoming increasingly stringent. In particular, the 25% small offset collision test results in a smaller overlap with the front bumper beam, causing the A-pillar to bear the direct force. Without the resistance of the front bumper beam, the force on the A-pillar increases dramatically, potentially causing it to bend. Utility Model Content

[0004] In view of this, the present application provides an A-pillar assembly, a body-in-white, and a vehicle. The present application is beneficial to improving the energy absorption effect of the A-pillar and reducing the probability of the A-pillar bending during a collision.

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

[0006] This application provides an A-pillar assembly, including a front connecting section and an A-pillar arranged sequentially along a first direction, with an energy-absorbing section between the front connecting section and the A-pillar; in a plane parallel to the first and second directions, the energy-absorbing section is located on the side of the front connecting section facing the A-pillar, and the energy-absorbing section is inclined to the front connecting section, the energy-absorbing section being used to reduce the impact force transmitted from the front connecting section to the A-pillar during a collision;

[0007] Wherein, the first direction and the second direction are perpendicular to each other.

[0008] This embodiment of the application incorporates an energy-absorbing section between the front connecting section and the A-pillar. This energy-absorbing section is inclined to the front connecting section and is substantially parallel to the A-pillar. The inclusion of this energy-absorbing section increases the length of the energy-absorbing area within the A-pillar assembly, enhancing the energy absorption effect. This reduces the impact force transmitted from the front connecting section to the A-pillar during a collision, thereby reducing the likelihood of the A-pillar bending.

[0009] In one possible implementation of this application, the strength of the energy-absorbing section is less than the strength of the A-pillar.

[0010] This application embodiment sets the strength of the energy-absorbing section to be less than that of the A-pillar, thereby making it easier for the energy-absorbing component to deform and absorb collision energy during a collision, reducing the impact force on the A-pillar and thus reducing the probability of the A-pillar bending.

[0011] In one possible implementation of this application, the front-end connecting section includes a side panel connector and a front-end connector, which are connected along a third direction; the A-pillar includes an upper A-pillar beam reinforcement and an inner A-pillar plate, which are connected along the third direction.

[0012] The energy-absorbing section includes an A-pillar connector and an A-pillar inner panel connector. The two ends of the A-pillar connector are respectively connected to the side panel connector and the upper beam reinforcement of the A-pillar. The two ends of the A-pillar inner panel connector are respectively connected to the front connector and the inner panel of the A-pillar.

[0013] Among them, the first direction, the second direction, and the third direction are perpendicular to each other.

[0014] In this embodiment, the side panel connector and the upper A-pillar beam reinforcement are connected by an A-pillar connector. This allows the A-pillar connector to absorb the impact force transmitted from the side panel connector to the upper A-pillar beam reinforcement during a collision, thereby reducing the likelihood of the upper A-pillar beam reinforcement bending. Similarly, the inner A-pillar panel connector connects the front panel connector and the inner A-pillar panel. This also allows the inner A-pillar panel connector to absorb the impact force transmitted from the front panel connector to the inner A-pillar panel during a collision, further reducing the likelihood of the inner A-pillar panel bending.

[0015] In one possible implementation of this application, the front-end connecting section includes a side panel connector and a front-end connector, which are connected along a third direction; the A-pillar includes an upper A-pillar beam reinforcement and an inner A-pillar plate, which are connected along the third direction.

[0016] The energy-absorbing section includes an A-pillar connector, with its two ends connected to the side panel connector and the upper beam reinforcement of the A-pillar, respectively, and the front end connector connected to the inner panel of the A-pillar.

[0017] Among them, the first direction, the second direction, and the third direction are perpendicular to each other.

[0018] In this embodiment, the side wall connector and the upper beam reinforcement of the A-pillar are connected by the A-pillar connector. In the event of a collision, the A-pillar connector can absorb the impact force transmitted from the side wall connector to the upper beam reinforcement of the A-pillar, thereby reducing the probability of the upper beam reinforcement of the A-pillar bending.

[0019] In one possible implementation of this application, the front-end connecting section includes a side panel connector and a front-end connector, which are connected along a third direction; the A-pillar includes an upper A-pillar beam reinforcement and an inner A-pillar plate, which are connected along the third direction.

[0020] The energy-absorbing section includes an A-pillar inner panel connector, the side panel connector is connected to the upper side beam reinforcement of the A-pillar, and the two ends of the A-pillar inner panel connector are respectively connected to the front end connector and the A-pillar inner panel;

[0021] Among them, the first direction, the second direction, and the third direction are perpendicular to each other.

[0022] In this embodiment, the front connector and the A-pillar inner panel are connected by an A-pillar inner panel connector, so that when a collision occurs, the A-pillar inner panel connector can absorb the impact force transmitted from the front connector to the A-pillar inner panel, thereby reducing the probability of the A-pillar inner panel bending.

[0023] In one possible implementation of this application, an A-pillar reinforcement is further included. Along the first direction, the side panel connector is connected to the A-pillar reinforcement; along the second direction, the A-pillar reinforcement is connected to the A-pillar connector and the upper beam reinforcement of the A-pillar.

[0024] This application embodiment improves the connection strength of the A-pillar by setting an A-pillar reinforcement member, which connects the side wall connector, the A-pillar connector, and the upper beam reinforcement member of the A-pillar.

[0025] In one possible implementation of this application, a front wall panel assembly is also included, which is connected to the energy-absorbing section along the third direction.

[0026] This embodiment of the application arranges the front panel assembly on one side of the energy-absorbing section along the third direction, thereby utilizing the energy-absorbing section to absorb the impact force transmitted from the third direction, reducing the impact on the front panel assembly, and effectively protecting the front panel assembly.

[0027] In one possible implementation of this application, the front connecting section, the energy-absorbing section, and the A-pillar are welded sequentially along the first direction; and the front wall panel assembly is welded to the energy-absorbing section along the third direction.

[0028] This embodiment of the application uses welding to connect the front connecting section, energy-absorbing section, A-pillar, and front wall panel assembly into one unit, which helps to ensure the overall strength and rigidity of the A-pillar assembly, thereby meeting the requirements of safety and durability. Welding also offers advantages such as low cost, high connection efficiency, and good sealing.

[0029] This application also provides a body-in-white, including any of the A-pillar components described above.

[0030] The body-in-white of this application embodiment uses the above-mentioned A-pillar assembly, so the A-pillar assembly has a better energy absorption effect, which can reduce the impact force transmitted from the front connecting section to the A-pillar during a collision, thereby reducing the probability of the A-pillar bending.

[0031] This application also provides a vehicle, including the body-in-white as described above.

[0032] The vehicle in this embodiment uses the aforementioned body-in-white, thus reducing the probability of the A-pillar bending during a collision. Attached Figure Description

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] As described in the background section, the A-pillar in the related technology is prone to bending during a 25% small offset collision. This problem arises because the A-pillar in the related technology is inclined towards and directly connected to the front connector. During a 25% small offset collision, the impact force is directly transferred from the front connector to the A-pillar, making it prone to bending.

[0050] In view of this, the embodiments of this application aim to provide an A-pillar assembly, a body-in-white, and a vehicle, by setting an energy-absorbing section between the front connecting section and the A-pillar. The energy-absorbing section is inclined to the front connecting section and is generally parallel to the A-pillar. The setting of the energy-absorbing section increases the length of the energy-absorbing area in the A-pillar assembly, improves the energy absorption effect, thereby reducing the impact force transmitted from the front connecting section to the A-pillar during a collision, and thus reducing the probability of the A-pillar bending.

[0051] The embodiments of this application are described in detail below with reference to the accompanying drawings, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. It should be noted that, in the description of the embodiments of this application, the first direction X, the second direction Y, and the third direction Z are three different directions in three-dimensional space. The first direction X, the second direction Y, and the third direction Z can be perpendicular to each other. The first direction X can be, for example, the vehicle length direction, the second direction Y can be, for example, the vehicle height direction, and the third direction Z can be, for example, the vehicle width direction.

[0052] This application provides an A-pillar assembly, a body-in-white, and a vehicle to reduce the probability of A-pillar bending during a collision. It should be noted that the vehicle in this application can refer to a large vehicle, a small vehicle, a special-purpose vehicle, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Vehicles generally have a body, with A-pillars located on both sides of the windshield. The A-pillars connect the roof and the front end of the vehicle, bearing the crucial responsibility of supporting the body and maintaining vehicle stability. In the event of a collision, the A-pillars can absorb and disperse some of the impact force, providing additional protection for occupants.

[0053] Please refer to Figures 1-5This application provides an A-pillar assembly, including a front connecting section 100 and an A-pillar 200 sequentially arranged along a first direction X. The front connecting section 100 connects the A-pillar 200 to parts at the front of the vehicle. A cavity is formed within the front connecting section 100 to buffer the impact force transmitted from the front of the vehicle to the A-pillar 200. In this embodiment, an energy-absorbing section 300 is provided between the front connecting section 100 and the A-pillar 200. In a plane parallel to the first direction X and the second direction Y, the energy-absorbing section 300 is located on the side of the front connecting section 100 facing the A-pillar 200 and is inclined to the front connecting section 100. The extending direction of the energy-absorbing section 300 is generally parallel to the A-pillar 200. The energy-absorbing section 300 is used to reduce the impact force transmitted from the front connecting section 100 to the A-pillar 200 during a collision. It is understood that the shape and structure of the energy-absorbing section 300 in this embodiment can be set based on the shape and structure of the front connecting section 100 and the A-pillar 200. The energy-absorbing section 300 needs to be compatible with the front connecting sections 100 and A-pillars 200 on both sides to ensure the aesthetic appearance of the vehicle. The interior of the energy-absorbing section 300 can have cavities or other structures to deform during a collision and absorb collision energy. Figure 1 and Figure 2 The middle arrow indicates the direction of force F transmission when the front of the vehicle is hit by a collision. Figure 1 and Figure 2 It can be seen that when the front of the vehicle is impacted, the impact force F first reaches the front connecting section 100, which can deform under the force to absorb part of the impact force F; then, the impact force F reaches the energy-absorbing section 300, which can deform under the force to further absorb part of the impact force F; finally, the impact force F reaches the A-pillar 200. Through the two absorption and buffering by the front connecting section 100 and the energy-absorbing section 300, the intensity of the impact force reaching the A-pillar 200 can be significantly reduced, thereby reducing the probability of the A-pillar bending.

[0054] This embodiment of the application provides an energy-absorbing section 300 between the front connecting section 100 and the A-pillar 200. The energy-absorbing section 300 is inclined to the front connecting section 100 and is generally parallel to the A-pillar 200. It is understood that by providing the energy-absorbing section 300, the length of the energy-absorbing area in the A-pillar assembly is increased compared to related technologies (in related technologies, the energy-absorbing area only includes the front connecting section, while in this embodiment, the energy-absorbing area includes both the front connecting section 100 and the energy-absorbing section 300), thus improving the energy absorption effect. This reduces the impact force transmitted from the front connecting section 100 to the A-pillar 200 during a collision, thereby reducing the probability of the A-pillar 200 bending.

[0055] In this embodiment, the strength of the energy-absorbing section 300 is less than the strength of the A-pillar 200.

[0056] In this embodiment, by setting the strength of the energy-absorbing section 300 to be less than that of the A-pillar 200, the energy-absorbing component can more easily deform to absorb collision energy during a collision, thereby reducing the impact force on the A-pillar 200 and reducing the probability of the A-pillar 200 bending.

[0057] Optionally, in this embodiment of the application, the energy-absorbing section 300 is a high-strength steel section, and the A-column 200 is a hot-formed steel column.

[0058] In this embodiment, the energy-absorbing section 300 is made of high-strength steel with a yield strength of 260 MPa and a tensile strength of 380 MPa, and the A-pillar 200 is made of hot-formed steel with a yield strength of 1000 MPa and a tensile strength of 1400 MPa. By utilizing the strength difference between the two materials, the energy-absorbing section 300 can fully absorb the collision energy, reduce the impact force on the A-pillar 200, and thus reduce the probability of the A-pillar 200 bending.

[0059] Please continue to refer to Figure 3 In one possible implementation, the front-end connecting segment 100 of this embodiment includes a side-mounted connector 110 and a front-end connector 120, which are connected along the third direction Z. Exemplarily, both the side-mounted connector 110 and the front-end connector 120 are generally L-shaped, and they can together form a front-end connecting segment 100 with a generally rectangular cross-section along the third direction Z. The connection of the side-mounted connector 110 and the front-end connector 120 forms a cavity, giving the front-end connecting segment 100 an energy-absorbing and buffering function. The A-pillar 200 includes an upper A-pillar beam reinforcement 210 and an inner A-pillar plate 220, which are connected along the third direction Z. It is understood that the combined structure of the upper A-pillar beam reinforcement 210 and the inner A-pillar plate 220 can improve the strength of the A-pillar itself.

[0060] The energy-absorbing section 300 in this embodiment includes an A-pillar connector 310 and an A-pillar inner panel connector 320. The shape of the A-pillar connector 310 is adapted to the shape of the side panel connector 110 and the A-pillar upper beam reinforcement 210, and both ends of the A-pillar connector 310 are respectively connected to the side panel connector 110 and the A-pillar upper beam reinforcement 210. The shape of the A-pillar inner panel connector 320 is adapted to the shape of the front end connector 120 and the A-pillar inner panel 220, and both ends of the A-pillar inner panel connector 320 are respectively connected to the front end connector 120 and the A-pillar inner panel 220.

[0061] In this embodiment, the A-pillar connector 310 connects the side wall connector 110 and the A-pillar upper beam reinforcement 210. This allows the A-pillar connector 310 to absorb the impact force transmitted from the side wall connector 110 to the A-pillar upper beam reinforcement 210 during a collision, thereby reducing the likelihood of the A-pillar upper beam reinforcement 210 bending. Similarly, the A-pillar inner panel connector 320 connects the front connector 120 and the A-pillar inner panel 220. This also allows the A-pillar inner panel connector 320 to absorb the impact force transmitted from the front connector 120 to the A-pillar inner panel 220 during a collision, further reducing the likelihood of the A-pillar inner panel 220 bending. Through this structure, both the A-pillar upper beam reinforcement 210 and the A-pillar inner panel 220 receive good impact protection, thus reducing the probability of the A-pillar bending during a collision.

[0062] In another possible implementation, the energy-absorbing section 300 of this embodiment may only include an A-pillar connector 310. The shape of the A-pillar connector 310 is adapted to the shape of the side wall connector 110 and the A-pillar upper beam reinforcement 210. The two ends of the A-pillar connector 310 are respectively connected to the side wall connector 110 and the A-pillar upper beam reinforcement 210. The front connector 120 is directly connected to the A-pillar inner panel 220.

[0063] In this embodiment, the A-pillar connector 310 connects the side panel connector 110 and the A-pillar upper beam reinforcement 210. Therefore, in the event of a collision, the A-pillar connector 310 can absorb the impact force transmitted from the side panel connector 110 to the A-pillar upper beam reinforcement 210, thereby reducing the probability of the A-pillar upper beam reinforcement 210 bending. Through this structure, the A-pillar upper beam reinforcement 210 can receive better impact protection, thus reducing the probability of the A-pillar bending during a collision.

[0064] In another possible implementation, the energy-absorbing section 300 of this embodiment may only include the A-pillar inner panel connector 320. The shape of the A-pillar inner panel connector 320 is adapted to the shape of the front connector 120 and the A-pillar inner panel 220, and both ends of the A-pillar inner panel connector 320 are respectively connected to the front connector 120 and the A-pillar inner panel 220. The side panel connector 110 is directly connected to the upper side beam reinforcement 210 of the A-pillar.

[0065] In this embodiment, the front connector 120 and the A-pillar inner panel 220 are connected by an A-pillar inner panel connector 320. This allows the A-pillar inner panel connector 320 to absorb the impact force transmitted from the front connector 120 to the A-pillar inner panel 220 during a collision, thereby reducing the likelihood of the A-pillar inner panel 220 bending. This structure provides better impact protection for the A-pillar inner panel 220, thus reducing the probability of the A-pillar bending during a collision.

[0066] Please continue to refer to Figures 1-3This application embodiment also includes an A-pillar reinforcement 130, with the side panel connector 110 connected to the A-pillar reinforcement 130 along the first direction X. Along the second direction Y, the A-pillar reinforcement 130 is connected to the A-pillar connector 310 and the upper beam reinforcement 210 of the A-pillar.

[0067] In this embodiment of the application, by setting an A-pillar reinforcement 130, which connects to the side wall connector 110, the A-pillar connector 310 and the A-pillar upper beam reinforcement 210, the connection strength of the A-pillar 200 can be improved by using the A-pillar reinforcement 130.

[0068] Please continue to refer to Figures 1-5 This application embodiment also includes a front wall panel assembly 400, which is connected to the energy-absorbing section 300 along the third direction Z. Exemplarily, the front wall panel assembly 400 of this embodiment includes a windshield crossbeam 410, a windshield reinforcement 420, and a front wall panel 430. The windshield crossbeam 410 is connected to the energy-absorbing section 300 along the third direction Z. Along the second direction Y, both ends of the windshield reinforcement 420 are respectively connected to the windshield crossbeam 410 and the front wall panel 430.

[0069] In this embodiment, the front wall panel assembly 400 is positioned on the side of the energy absorption section 300 along the third direction Z, thereby absorbing the impact force transmitted from the third direction Z by the energy absorption section 300, reducing the impact on the front wall panel assembly 400, and effectively protecting the front wall panel assembly 400.

[0070] Along the first direction X, the front connecting section 100, the energy-absorbing section 300 and the A-pillar 200 are welded in sequence; along the third direction Z, the front wall panel assembly 400 is welded to the energy-absorbing section 300.

[0071] In this embodiment, the front connecting section 100, energy-absorbing section 300, A-pillar 200, and front wall panel assembly 400 are connected as a single unit by welding. This method helps to ensure the overall strength and rigidity of the A-pillar assembly, thereby meeting the requirements for safety and durability. Welding also offers advantages such as low cost, high connection efficiency, and good sealing.

[0072] For details, please continue to refer to... Figure 4 and Figure 5In this embodiment, the A-pillar assembly can be divided into three parts—side panel assembly, inner panel assembly, and front wall panel assembly 400—based on the position of the parts in the vehicle width direction (i.e., the third direction Z). The side panel assembly is the exterior surface of the vehicle in the width direction. The side panel assembly includes a side panel connector 110, an A-pillar reinforcement 130, an A-pillar connector 310, and an A-pillar upper side beam reinforcement 210. The inner panel assembly includes a front end connector 120, an A-pillar inner panel connector 320, and an A-pillar inner panel 220. The front wall panel assembly 400 includes a windshield crossbeam 410, a windshield reinforcement 420, and a front wall panel 430. When assembling the A-pillar assembly, the side wall connector 110, A-pillar reinforcement 130, A-pillar connector 310 and A-pillar upper beam reinforcement 210 are welded in sequence to form the side wall assembly. The front connector 120, A-pillar inner panel connector 320 and A-pillar inner panel 220 are welded in sequence to form the inner panel assembly. The windshield crossbeam 410, windshield reinforcement 420 and front wall panel 430 are welded in sequence to form the front wall panel assembly 400. Then the side wall assembly, inner panel assembly and front wall panel assembly 400 are welded to form the A-pillar assembly.

[0073] This application also provides a body-in-white, including the aforementioned A-pillar assembly.

[0074] The body-in-white of this application embodiment uses the above-mentioned A-pillar assembly, so the A-pillar assembly has a better energy absorption effect, which can reduce the impact force transmitted from the front connecting section to the A-pillar during a collision, thereby reducing the probability of the A-pillar bending.

[0075] This application also provides a vehicle including the aforementioned body-in-white.

[0076] The vehicle in this embodiment uses the aforementioned body-in-white, thus reducing the probability of the A-pillar bending during a collision.
