Description

Technical Field

[0001] This utility model relates to the field of vehicle body, specifically to an A-pillar assembly and a vehicle having the A-pillar assembly. Background Technology

[0002] With the rapid development of the automotive industry, the proportion of electric and hybrid vehicles is increasing, and users are paying more and more attention to the safety performance of vehicles. Safety performance has become an important consideration for consumers when purchasing a car.

[0003] A vehicle's safety performance is affected by multiple factors.

[0004] Analyzing the deformation trends of automobiles in frontal and offset collisions, after the front of the vehicle is impacted by a collision, the collision force is transmitted to the rear of the vehicle through the front bumper beam and longitudinal beams. The A-pillar of the vehicle is the dispersion point of the collision force transmission. The structure here affects the transmission of collision force and the absorption of collision energy, thereby affecting the safety space of the passenger compartment.

[0005] During vehicle development, the A-pillar structure is limited by the tire envelope and the front door stop, and its X-axis dimension is generally no more than 230mm. Its design affects the A-pillar's impact resistance and deformation resistance. In order to ensure the safety of the occupants, the A-pillar is required to have sufficient strength to absorb some of the collision energy, disperse the collision force, and effectively support the vehicle body.

[0006] In common car models, the door ring reinforcement plate is welded to the upper and lower hinge reinforcement plates of the box-shaped A-pillar, respectively. This structure can meet the safety collision requirements and the performance requirements of the front door mounting point. However, in small offset collisions, due to the large force on the cross section, the overall deformation of the A-pillar is large, and the weld points at the stop edge are prone to tearing, leading to uncontrollable deformation. These risks make it necessary to strengthen the rigidity of the A-pillar cavity.

[0007] Meanwhile, a search revealed that while existing patent 201821687003.7 - A Reinforcing Structure for Automobile A-pillar and Automobile - can achieve A-pillar reinforcement, the overall structure is relatively simple, and the increase in strength or stiffness is limited.

[0008] Therefore, in order to improve or solve at least one of the above problems, it is necessary to optimize the design of the existing A-pillar structure. Utility Model Content

[0044] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0045] An A-pillar assembly includes a side panel assembly 1, a door ring assembly 2, and an A-pillar vertical plate assembly 3. The side panel assembly 1, door ring assembly 2, and A-pillar vertical plate assembly 3 are connected sequentially. The door ring assembly 2 and A-pillar vertical plate assembly 3 are arranged opposite to each other. The side panel assembly 1 overlaps the door ring assembly 2. The side panel assembly 1, door ring assembly 2, and A-pillar vertical plate assembly 3 form a box structure. The A-pillar assembly disclosed in this utility model forms a box structure through the cooperation of the side panel assembly 1, door ring assembly 2, and A-pillar vertical plate assembly 3. This arrangement effectively ensures the overall structural strength of the A-pillar assembly and also provides anti-collision performance.

[0046] The essence of this invention is to improve the anti-collision performance of the A-pillar assembly by changing the structure of the traditional A-pillar assembly and increasing the strength of the A-pillar assembly itself.

[0047] In this utility model, the A-pillar assembly mainly includes a side outer panel assembly 1, a door ring panel assembly 2, and an A-pillar vertical panel assembly 3. In this utility model, the side outer panel assembly 1 is mainly a part of the front end of the vehicle side outer panel, and the door ring panel assembly 2 is a part of the front end of the vehicle front door ring. Based on this arrangement, the side outer panel assembly 1 and the door ring panel assembly 2 disclosed in this utility model can be produced together with the vehicle side outer panel and the vehicle front door ring, respectively, reducing the cost of separate mold opening in the actual production process.

[0048] In this utility model, the side panel assembly 1, the door ring assembly 2, and the A-pillar vertical plate assembly 3 are connected in sequence; the door ring assembly 2 and the A-pillar vertical plate assembly 3 are arranged opposite to each other; the side panel assembly 1 overlaps the door ring assembly 2; the side panel assembly 1, the door ring assembly 2, and the A-pillar vertical plate assembly 3 form a box structure; the door ring assembly 2 and the A-pillar vertical plate assembly 3 are arranged opposite to each other, and the two form the main structure of the above-mentioned box structure, while one of the side panel assemblies 1 acts as a reinforcing member, and the other two act as exterior trim members.

[0049] The side panel assembly 1, door ring assembly 2, and A-pillar vertical plate assembly 3 of this utility model form a box structure, making the A-pillar assembly form a U-shaped structure. This design can not only reduce the overall weight of the A-pillar assembly, but also improve the structural strength of the A-pillar assembly itself.

[0050] Furthermore, in this utility model, the side panel assembly 1 includes a side panel 101; the door ring assembly 2 includes a door ring 2-1; and the A-pillar vertical plate assembly 3 includes a vertical plate body 301. In this utility model, the side panel 101 is the main structural part of the side panel assembly 1, the door ring 2-1 is the main structural part of the door ring assembly 2, and the vertical plate body 301 is the main structural part of the A-pillar vertical plate assembly 3. In this utility model, the side panel 101 overlaps the door ring 2-1; the horizontal cross-section of the door ring 2-1 and the vertical plate body 301 is U-shaped; the door ring 2-1 and the vertical plate body 301 are arranged opposite to each other and connected. Based on the above, the door ring 2-1 and the vertical plate body 301 form the box structure of the A-pillar assembly, which effectively ensures the structural strength of the A-pillar assembly.

[0051] Furthermore, in this utility model, the door ring plate 2-1 is provided with a reinforcing mechanism on the side near the A-pillar vertical plate assembly 3; the reinforcing mechanism includes a hinge reinforcing plate 201 disposed on the door ring plate 2-1; in this utility model, the hinge reinforcing plate 201 is distributed at the upper hinge mounting point and the lower hinge mounting point of the A-pillar assembly; both ends of the hinge reinforcing plate 201 simultaneously press against the upper hinge mounting point and the lower hinge mounting point; at the same time, the hinge reinforcing plate 201 of this utility model is an integral plate structure. By setting the integral hinge reinforcing plate 201, this utility model makes it equivalent to embedding an integral plate on the inner side of the A-pillar assembly, which can increase the overall structural strength and rigidity of the A-pillar assembly to a certain extent; increase the A-pillar assembly's resistance to deformation; at the same time, the integral hinge reinforcing plate 201 can reduce the number of A-pillar assembly parts, which is beneficial for actual assembly and reduces assembly processes.

[0052] In this utility model, the hinge reinforcement plate 201 is arranged inside the door ring plate 2-1, and the hinge reinforcement plate 201 is distributed at the upper hinge mounting point and the lower hinge mounting point of the A-pillar assembly; both ends of the hinge reinforcement plate 201 simultaneously press against the upper hinge mounting point and the lower hinge mounting point; in the existing A-pillar assembly, the traditional hinge reinforcement plate is divided into an upper hinge reinforcement plate and a lower hinge reinforcement plate; although the split traditional hinge reinforcement plate can increase the rigidity and strength of the A-pillar assembly to a certain extent, the overall arrangement is relatively... While the design is cumbersome, during small offset collisions, the A-pillar experiences significant deformation due to the large force on the cross-section, and the weld points at the stop edge are prone to tearing, leading to uncontrollable deformation. This invention transforms the traditional split hinge reinforcement plate into a single integral reinforcement plate, meaning that the hinge reinforcement plate 201 in this invention is a single plate structure. It extends from above the door ring plate 2-1 to below the door ring plate 2-1, greatly improving the overall structural rigidity of the door ring plate 2-1, thereby enhancing the rigidity and strength of the A-pillar assembly.

[0053] Furthermore, in the present utility model, the strengthening mechanism further includes a connecting bracket 202 provided on the door ring plate member 2-1; one end of the connecting bracket 202 is connected to the hinge strengthening plate 201 on the door ring plate member 2-1, and the other end is connected to the A-pillar vertical plate assembly 3; the strengthening mechanism includes two connecting brackets 202 distributed at intervals; the vertical cross-section of each connecting bracket 202 is in a shape of a reversed L; the arrangement of the connecting brackets 202 enables the formation of a support inside the A-pillar assembly, which can better ensure the overall structural stiffness of the A-pillar assembly; at the same time, in the present utility model, the A-pillar assembly is equivalent to a box structure with a hollow interior, that is, the A-pillar assembly has an inner cavity structure, and the connecting brackets 202 can be arranged in this inner cavity, thereby increasing or decreasing the stiffness and strength of the A-pillar assembly, and also facilitating the subsequent connection and assembly between the door ring plate member 2-1 and the A-pillar vertical plate assembly 3.

[0054] At the same time, in the present utility model, the strengthening mechanism includes two connecting brackets 202 distributed at intervals; the two connecting brackets 202 are distributed at the upper and lower ends of the A-pillar body. Such an arrangement can not only increase the stiffness and strength of the inner cavity of the A-pillar assembly, but also facilitate the subsequent connection of the A-pillar vertical plate assembly 3.

[0055] In addition, in the present utility model, the vertical cross-section of each connecting bracket 202 is in a shape of a reversed L; based on such an arrangement, the present utility model can ensure the self-structural strength and stiffness of the connecting bracket 202, because such a design method makes the connecting bracket 202 equivalent to a box structure, thus ensuring its own stiffness.

[0056] Furthermore, in the present utility model, a vertical plate strengthening plate 302 is provided on one side of the vertical plate body 301 close to the door ring plate member 2-1; the vertical plate strengthening plate 302 is arranged close to the vehicle body chassis side; the vertical plate strengthening plate 302 can ensure the self-structural strength of the lower end of the vertical plate body 301. At the same time, in the present utility model, the vertical plate strengthening plate 302 and the hinge strengthening plate 201 partially overlap in the longitudinal projection; the longitudinal projection of the vertical plate strengthening plate 302 and the hinge strengthening plate 201 here mainly refers to the front view projection. Because in actual arrangement, the vertical plate strengthening plate 302 and the hinge strengthening plate 201 are arranged longitudinally, that is, arranged along the vehicle body Z direction, so in the present utility model, it is equivalent that the vertical plate strengthening plate 302 and the hinge strengthening plate 201 have an overlapping area in the vehicle body Z direction; for better use effects, the present utility model requires that the vertical plate strengthening plate 302 and the hinge strengthening plate 201 have an overlapping amount in the Z direction and overlap with the longitudinal beam in the vehicle body direction to effectively resist the collision force from the longitudinal beam.

[0057] The vertical plate strengthening plate 302 is in a U-shaped structure, with horizontal and vertical ribs to enhance stiffness and reduce the fitting surface.

[0058] Furthermore, in this utility model, the door ring plate 2-1 includes a door ring main body 21, with a door ring upper body 22 at one end and a door ring lower body 23 at the other end; the vertical plate body 301 includes a vertical plate main body 31, with a vertical plate upper body 32 at one end and a vertical plate lower body 33 at the other end; the side enclosure outer plate 101 includes a side enclosure main body 11, with a side enclosure upper body 12 at one end and a side enclosure lower body 13 at the other end; the side enclosure upper body, door ring upper body 22, and vertical plate upper body 32 are connected in sequence; the side enclosure upper body, door ring upper body 22, and vertical plate upper body 32 are all inclined; the side enclosure main body 11, door ring main body 21, and vertical plate main body 31 are connected in sequence; the side enclosure lower body 23... 3. The lower part of the door ring 23 and the lower part of the vertical plate 33 are connected in sequence. Through the above design, it can be seen that the side panel 101, door ring 2-1, and vertical plate body 301 of this utility model have a three-section structure. In subsequent use, the upper part of the side panel, the upper part of the door ring 22, and the upper part of the vertical plate 32 are connected in sequence to form the upper cavity of the A-pillar assembly; the main body of the side panel 11, the main body of the door ring 21, and the main body of the vertical plate 31 are connected in sequence to form the vertical cavity of the A-pillar assembly; and the lower part of the side panel 13, the lower part of the door ring 23, and the lower part of the vertical plate 33 are connected in sequence to form the lower cavity of the A-pillar assembly. Through the coordinated use of multiple cavities, the collision force transmitted from different parts of the front of the vehicle body can be resisted and transferred to the rear of the vehicle body, ensuring the rigid structure of the vehicle and the safety of the occupants.

[0059] Furthermore, in this utility model, the A-pillar vertical plate assembly 3 overlaps with the door sill beam of the vehicle body; this utility model is based on such a design; the A-pillar vertical plate assembly 3 fits against the inner side of the door sill and is connected to the vertical section of the door sill, ensuring overlap while reducing the overlapping area and reducing weight without reducing performance.

[0060] A vehicle including the A-pillar assembly.

[0061] specific:

[0062] The A-pillar assembly disclosed in this utility model includes a side outer panel assembly 1, a door ring panel assembly 2, and an A-pillar vertical panel assembly 3.

[0063] The A-pillar assembly disclosed in this utility model connects the front of the cabin side beam and the cabin longitudinal beam, and the rear of the assembly connects the upper side beam of the side panel and the door sill.

[0064] The A-pillar assembly includes the side outer panel assembly 1, the door ring panel assembly 2, and the A-pillar vertical panel assembly 3.

[0065] Regarding the side panel assembly 1, the side panel assembly 1 is mainly the front end structure of the side panel of the whole vehicle; it is the outermost sheet metal of the A-pillar assembly.

[0066] The door ring plate assembly 2 is the front section structure of the front door ring of the whole vehicle. In the present utility model, the door ring plate assembly 2 is the middle sheet metal structure of the A-pillar assembly, which is different from the A-pillar reinforcement plate of traditional vehicle models. The door ring assembly is an integral part surrounding the front door, reducing the number of molds. High-strength steel or hot forming is selected to improve performance and reduce weight.

[0067] The door ring plate assembly 2 has a C-shaped structure, and is connected to the outer panel assembly 1 of the side wall on the outside. It includes an obliquely upward cavity matching the upper side beam of the side wall, a vertical cavity matching the vertical plate of the A-pillar, a horizontal cavity matching the sill, and a mating surface connected to the outer plate of the engine compartment side beam.

[0068] During actual design, a door ring upper reinforcement plate can be provided inside the door ring plate part 2-1, which is located in the obliquely upward cavity matching the upper side beam of the side wall, has a C-shaped structure, and is integrally formed with the door ring assembly to improve the Z-direction and X-direction support strengths.

[0069] A hinge reinforcement plate 201 is also provided inside the door ring plate part 2-1, which is located in the vertical cavity matching the vertical plate assembly 3 of the A-pillar, has a box-shaped structure, and forms a square cavity as a whole to improve the stiffness of the hinge installation point and the X-direction support strength.

[0070] It is different from the local reinforcement of the traditional upper and lower hinges, and is a integral structure. While strengthening the stiffness of the hinge installation point, it improves the X-direction support and can effectively resist the impact force transmitted from the side of the vehicle.

[0071] The vertical plate assembly 3 of the A-pillar mainly includes a vertical plate body 301, which is located at the innermost side of the A-pillar assembly.

[0072] Different from the formation of the vertical plate assembly 3 of the A-pillar of traditional vehicle models by dividing into upper and lower parts, the vertical plate body 301 of the present utility model adopts integral hot forming to improve the X-direction performance.

[0073] The vertical plate body 301 has a C-shaped structure, including an obliquely upward cavity and a vertical cavity matching the door ring plate assembly 2 on the outside, a horizontal cavity matching the sill assembly, and a mating surface connected to the inner plate of the engine compartment side beam.

[0074] For the vertical plate reinforcement plate 302, it has a U-shaped structure and is spliced with the vertical plate body 301.

[0075] The vertical plate reinforcement plate 302 is aligned with the engine compartment longitudinal beam and bears the impact force transmitted from the longitudinal beam.

[0076] The outer panel assembly 1 of the side wall, the door ring plate assembly 2 and the vertical plate assembly 3 of the A-pillar form a closed cavity composed of a C-shaped structure.

[0077] There are upper and lower connecting brackets 202 in the C-shaped cavity, which are located at positions with relatively large impact forces, run through the entire cavity, and strengthen the performance of the A-pillar assembly.

[0078] For the A-pillar assembly of the present utility model, the upper part decomposes the collision force transmitted from the side beam of the engine compartment and conducts it to the obliquely upward cavity and the vertical cavity of the A-pillar assembly. The impact energy is resisted through the sealed cavity, the hinge reinforcement plate 201 and the upper connecting bracket 202.

[0079] The lower part decomposes the collision force transmitted from the longitudinal beam and conducts it to the vertical cavity and the lower horizontal cavity. The impact energy is resisted through the sealed cavity, the hinge reinforcement plate 201 and the lower connecting bracket 202.

[0080] The A-pillar assembly forms a closed cavity together with the side outer panel assembly 1, the door ring panel assembly 2 and the A-pillar vertical plate assembly 3. Combining with the internal reinforcement plates and the upper and lower connecting brackets 202, the strength and stiffness of the A-pillar area are improved as a whole, effectively resisting the collision force and ensuring the safety of the occupant compartment space.

[0081] Embodiment 1:

[0082] According to the analysis of the frontal collision and offset collision of the vehicle, the collision force received by the A-pillar assembly comes from three aspects. One is the collision force transmitted from the side beam of the engine compartment, the second is the collision force transmitted from the longitudinal beam of the engine compartment, and the third is the collision force directly hitting the A-pillar assembly.

[0083] A good structure can effectively resist and decompose the collision force, avoiding the influence on the occupant compartment space after the vehicle is deformed by the impact.

[0084] Based on the collision requirements, the present utility model optimizes the structure of the existing A-pillar assembly.

[0085] As shown in the attached drawings, the A-pillar assembly of the present utility model is composed of the side outer panel assembly 1, the door ring panel assembly 2 and the A-pillar vertical plate assembly 3.

[0086] The door ring panel assembly 2 includes the door ring panel member 2-1, the hinge reinforcement plate 2 and the connecting bracket 202.

[0087] The A-pillar vertical plate assembly 3 includes the vertical plate body 301 and the vertical plate reinforcement plate 302.

[0088] In the present utility model, the side upper body member, the door ring upper body member and the vertical plate upper body member are sequentially connected to form the upper cavity of the A-pillar assembly; the side upper body member, the door ring upper body member and the vertical plate upper body member are all inclined; in the present utility model, the upper part of the vertical plate body 301 is in a stepped shape and slopes upward towards the interior of the vehicle, and the obliquely upward section of the door ring assembly is in a U-shape; based on the above docking, the above-mentioned upper cavity of the A-pillar assembly is formed.

[0089] In the present utility model, the side upper body member is outside the above-mentioned cavity, and the three are connected by structural flanges.

[0090] The upper cavity of the A-pillar assembly is generally limited by styling and stamping, with small dimensions in the Y and Z directions. There is a patch panel of the door ring assembly in the upper cavity of the A-pillar assembly, which enhances the Z-direction support strength of the cavity.

[0091] Add structural adhesive blocks in the overlapping area of the upper cavity of the A-pillar assembly to reduce the number and thickness of reinforcement plates, and enhance the strength and stiffness of the overlapping area and the cavity.

[0092] In the present utility model, the vertical cavity of the A-pillar assembly is formed by sequentially connecting the side wall main body member 11, the door ring main body member 21, and the vertical plate main body member 31; both the door ring main body member 21 and the vertical plate main body member 31 are in a U-shaped structure, and the two are butted to form the vertical cavity of the A-pillar assembly.

[0093] The vertical dimension of the overall cavity of the vertical cavity of the A-pillar assembly is limited by the size of the door stop, the internal space, and the stamping depth. The Y-direction dimension of the overall cavity is 150 mm, and the X-direction dimension is 200 mm.

[0094] The X-direction strength is supported by the hinge reinforcement plate 201 of the door ring plate assembly 2. The hinge reinforcement plate 201 is in a box-shaped structure and is welded to the door ring plate assembly 2.

[0095] The hinge reinforcement plate 201 has an uneven surface, which reduces the overlap while enhancing the stiffness.

[0096] The Y-direction strength is ensured by the cavity itself and the upper and lower connecting brackets 202. The connecting brackets 202 are in a U-shaped structure, welded to the door ring plate assembly 2 and the hinge reinforcement plate 201, and bolt-connected to the A-pillar vertical plate assembly 3.

[0097] The lower cavity of the A-pillar assembly is formed by sequentially connecting the lower part of the side wall member 13, the lower part of the door ring member 23, and the lower part of the vertical plate member 33.

[0098] The vertical plate reinforcement plate 302 and the hinge reinforcement plate 201 have an overlap in the Z direction and overlap with the longitudinal beam in the vehicle body direction, effectively resisting the collision force from the longitudinal beam.

[0099] The vertical plate reinforcement plate 302 is in a U-shaped structure, with ribs in the horizontal and vertical directions, enhancing the stiffness and reducing the mating surface.

[0100] The horizontal cavity is composed of the sill and the door ring plate assembly 2, and the two are butted in a U-shaped structure. The A-pillar vertical plate assembly 3 fits against the inner side of the sill and is connected to the vertical section of the sill. On the premise of ensuring the overlap, the overlapping area is reduced, and the weight is reduced without reducing the performance. The outer side wall assembly 1 is connected to the door ring plate assembly 2 and not to the sill.

[0101] At the same time, there is an aluminum profile sill reinforcement plate inside the above-mentioned horizontal cavity. Different from the traditional sheet metal reinforcement plate, the aluminum profile itself is a structural cavity and can be completely filled in the horizontal cavity to ensure the structural strength of the cavity. The collision force is transmitted to the rear side of the vehicle body through the horizontal cavity.

[0102] The A-pillar assembly disclosed in this utility model resists the impact force transmitted from different parts of the front of the vehicle body and transmits it to the rear of the vehicle body, thus protecting the rigid structure of the vehicle and ensuring the safety of the occupants.

[0103] Obviously, the specific implementation of this utility model is not limited to the above-mentioned methods. Any non-substantial improvements made using the inventive concept and technical solution of this utility model are within the protection scope of this utility model.
