Abstract
Description
Technical Field

[0002] With the development of the automotive industry, people's demands for vehicle safety are becoming increasingly stringent, and automotive safety regulations are becoming increasingly stringent. Among these, small offset collisions are the most severe. During small offset collisions, there is essentially no overlap between the impacting object and the vehicle's longitudinal beams. In these cases, the vehicle relies solely on the side beams for energy absorption. Furthermore, the impacting object pushes the wheels directly into the lower portion of the A-pillar, the first line of defense for the passenger compartment. Damage to the A-pillar can impact the safety of the passenger compartment. Offset collision regulations clearly stipulate the displacement and cracking of the A-pillar. Damage to the A-pillar can degrade the collision safety performance of the passenger compartment. Utility Model Content
[0003] The purpose of this application is to at least solve the technical problem that the A-pillar of the vehicle body is easily damaged during a small offset collision. This purpose is achieved through the following technical solutions:
[0004] A first aspect of the present application provides a vehicle body A-pillar structure, which is provided with a collision zone facing the wheel, and the vehicle body A-pillar structure includes: an A-pillar inner panel, which is provided on the inner side of the vehicle body A-pillar structure, and the A-pillar inner panel is provided with an inner welding plate that avoids the collision zone; an A-pillar outer panel, which is provided on the outer side of the vehicle body A-pillar structure and is connected to the A-pillar inner panel to form the vehicle body A-pillar structure, and the A-pillar outer panel is provided with an outer welding plate that avoids the collision zone, and the inner welding plate and the outer welding plate are spliced into a welded structure of the vehicle body A-pillar structure.
[0005] In some embodiments, the inner welding plate extends to the outer side of the A-pillar structure of the vehicle body and faces the wheel, and the outer welding plate is configured to match the inner welding plate and faces away from the wheel.
[0006] In some embodiments, the welded structure formed by splicing the inner welded plate and the outer welded plate is located on the outside of the A-pillar structure of the vehicle body and forms an obtuse angle structure with the collision zone facing the wheel.
[0007] In some embodiments, the welded structure formed by splicing the inner welded plate and the outer welded plate is located outside the A-pillar structure of the vehicle body and is bent into a coiled structure.
[0008] In some embodiments, a first clipping structure corresponding to the collision area is provided inside the inner panel of the A-pillar, and a second clipping structure corresponding to the collision area is provided inside the outer panel of the A-pillar. When the inner welding plate and the outer welding plate are in a spliced state, the first clipping structure and the second clipping structure are clipped to each other.
[0009] In some embodiments, the first clamping structure includes a first clamping plate provided with a clamping slot, and the second clamping structure includes a second clamping plate provided with a clamping hook capable of extending into the clamping slot.
[0010] In some embodiments, the A-pillar inner panel is configured as a hollow structure, and a first reinforcing rib corresponding to the collision zone is provided inside the A-pillar inner panel, and / or the A-pillar outer panel is configured as a hollow structure, and a second reinforcing rib corresponding to the collision zone is provided inside the A-pillar outer panel.
[0011] In some embodiments, the bottom of the vehicle body A-pillar structure forms an accommodating space for the vehicle body door sill, the first clamping structure and the second clamping structure are located above the vehicle body door sill, and the first reinforcing rib and the second reinforcing rib are located above the first clamping structure and the second clamping structure.
[0012] In some embodiments, the A-pillar inner panel covers the projection of the wheel onto the A-pillar inner panel, the collision zone is located on the A-pillar inner panel, and a reinforcement plate covering the collision zone is provided outside the A-pillar inner panel.
[0013] A second aspect of the present application provides a vehicle, the vehicle comprising a vehicle body and the vehicle body A-pillar structure of the first aspect of the present application.
[0014] The A-pillar structure of the vehicle body in the embodiment of the present application proposes to avoid the welding structure from the collision zone of the A-pillar structure of the vehicle body, so that the wheel does not directly collide with the welding structure of the A-pillar structure of the vehicle body, thereby reducing the phenomenon that the welding structure is easily punctured by the wheel tire during a small offset collision, and reducing the phenomenon that the A-pillar inner panel and the A-pillar outer panel collide and crack at the welding structure.
[0015] Specifically, those skilled in the art will understand that the collision zone of the A-pillar structure of the vehicle body directly opposite the wheel is the primary path for energy transfer in small-offset collisions and is also the primary stress point for energy transfer in small-offset collisions. Therefore, when the vehicle body is involved in a small-offset collision, the welded structure of the A-pillar structure of the vehicle body is prone to damage. To this end, the embodiments of the present application propose that the welded structure of the A-pillar structure of the vehicle body be located in a relatively weak area that deviates from the small-offset collision path, thereby reducing the risk of damage to the A-pillar structure of the vehicle body during small-offset collisions and improving the overall small-offset collision performance of the vehicle body.

[0031] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.
[0032] It should be understood that the terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, as used herein, the singular forms "a," "an," and "the" may also be intended to include the plural forms. The terms "comprise," "include," and "have" are inclusive and, therefore, specify the presence of the stated features, elements, and / or components, but do not preclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.
[0033] Although the terms first, second, etc. may be used herein to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms may only be used to distinguish one element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply a sequence or order when used herein. In addition, in the description of this application, unless otherwise clearly specified and limited, the terms "set" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.
[0034] For ease of description, spatial relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figures, such as "front", "back", "facing", "height direction", "bottom", "longitudinal", "outer", "inner", "middle", "thickness direction", etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation in addition to the orientation depicted in the figures. For example, if the mechanism in the figures is flipped, the element described as "below other elements or features" or "below other elements or features" will then be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The mechanism may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.
[0035] "Small offset collision" refers to the edge of the colliding vehicle, including the left or right side of the bumper before the collision, including 40% small offset collision and 25% small offset collision, etc. The percentage refers to the overlap between the vehicle body width and the barrier. The smaller the overlap, the smaller the force area of contact, and the higher the potential damage to the vehicle body and occupants. The general way to judge the quality of the vehicle body is to record and analyze the deformation of the vehicle body during and after the collision, and use dummies to collect damage values of various parts of the human body, so as to judge the vehicle body's ability to protect the occupants; "front" refers to the front direction of the vehicle, "rear" refers to the rear direction of the vehicle; "longitudinal" refers to the length direction of the vehicle.
[0036] At present, in order to improve the small offset collision performance of a vehicle, relevant technologies often meet the vehicle's small offset collision performance requirements by adding energy-absorbing plates or thickening the body sheet metal. Adding energy-absorbing plates or thickening the body sheet metal means that the weight of the entire vehicle needs to be increased, and the manufacturing cost of the entire vehicle will be increased.
[0037] In order to solve the technical problem of improving the small offset collision performance of the vehicle body without increasing the weight and cost of the vehicle body too much, the present applicant found that the welding structure of the vehicle body A-pillar structure is the weak point of the vehicle in small offset collision, such as Figure 1 and Figure 2 As shown, the weld flange 41 of the vehicle's A-pillar 40 faces the wheel A50. This weld flange 41 is easily squeezed, deformed, and cracked by the wheel A50. Furthermore, the weld flange 41 is also prone to puncturing the wheel A50, restricting the wheel A50's ability to steer and avoid danger. Therefore, this application proposes offsetting the weld structure of the vehicle's A-pillar structure from the primary path of energy transfer in small-offset collisions. This minimizes weight and cost, reduces the risk of damage to the vehicle's A-pillar structure during small-offset collisions, and improves the vehicle's small-offset collision performance.
[0038] Below through Figures 3 to 8 The small offset collision structure of the embodiment of the present application is described in detail.
[0039] like Figures 3 to 5 As shown, the present application provides a vehicle body A-pillar structure 10, which is provided with a collision zone facing the wheel 20. The vehicle body A-pillar structure 10 includes an A-pillar inner panel 11 and an A-pillar outer panel 12. The A-pillar inner panel 11 is provided on the inner side of the vehicle body A-pillar structure 10, and the A-pillar inner panel 11 is provided with an inner welding plate 110 that avoids the collision zone; the A-pillar outer panel 12 is provided on the outer side of the vehicle body A-pillar structure 10, and is connected to the A-pillar inner panel 11 to form the vehicle body A-pillar structure 10, and the A-pillar outer panel 12 is provided with an outer welding plate 120 that avoids the collision zone. The inner welding plate 110 and the outer welding plate 120 are spliced into a welding structure 13 of the vehicle body A-pillar structure 10.
[0040] In this embodiment, the vehicle body A-pillar structure 10 provided in the embodiment of the present application proposes to avoid the welding structure 13 from the collision area of the vehicle body A-pillar structure 10, so that the wheel 20 does not directly collide with the welding structure 13 of the vehicle body A-pillar structure 10, thereby reducing the phenomenon of the welding structure 13 puncturing the tire of the wheel 20 during a small offset collision of the vehicle, and reducing the phenomenon of the A-pillar inner panel 11 and the A-pillar outer panel 12 colliding and cracking at the welding structure 13.
[0041] Specifically, those skilled in the art will understand that the collision zone of the vehicle body A-pillar structure 10 directly opposite the wheel 20 is the primary path for small offset collision energy transfer and is also the primary stress point for small offset collision energy transfer. Therefore, when a small offset collision occurs, the weld structure 13 of the vehicle body A-pillar structure 10 is susceptible to damage. Therefore, the embodiments of the present application propose that the weld structure 13 of the vehicle body A-pillar structure 10 be located in a relatively weak area that deviates from the small offset collision path, thereby reducing the risk of damage to the vehicle body A-pillar structure 10 during a small offset collision and improving the overall small offset collision performance of the vehicle body.
[0042] In addition, the vehicle body A-pillar structure 10 is configured as a split structure composed of an A-pillar inner panel 11 and an A-pillar outer panel 12. Compared with the vehicle body A-pillar structure 10 with an integrated structure, the manufacturing difficulty and manufacturing cost of the vehicle body A-pillar structure 10 can be reduced. The A-pillar inner panel 11 and the A-pillar outer panel 12 are connected to each other by welding the inner welding plate 110 and the outer welding plate 120, thereby improving the connection reliability of the A-pillar inner panel 11 and the A-pillar outer panel 12.
[0043] It should be noted that the embodiments of the present application do not limit the specific structure and position of the welding structure 13 because the specific structure of the welding structure 13 includes an inclined structure and a bent structure, and the specific position of the welding structure 13 includes avoiding the collision zone toward the inside of the vehicle and avoiding the collision zone toward the outside of the vehicle. The positions of these structures all fall within the protection scope of the embodiments of the present application. The preferred embodiments of the welding structure 13 will be explained below.
[0044] The specific implementation of the vehicle body A-pillar structure 10 is described below through the preferred embodiment of the present application.
[0045] like Figures 3 to 5 As shown, in some embodiments, the inner welding plate 110 extends to the outside of the vehicle body A-pillar structure 10 and faces the wheel 20 , and the outer welding plate 120 is configured to match the inner welding plate 110 and faces away from the wheel 20 .
[0046] In this embodiment, the inner welded plate 110 extends to the outside of the A-pillar structure 10 of the vehicle body and faces the wheel 20. That is, the inner welded plate 110 is a whole piece facing the wheel 20. The whole piece of inner welded plate 110 has the advantages of balanced force and no obvious weak areas. It is not easy to tear in local areas, nor is it easy to cause stress concentration in local areas to puncture the tire.
[0047] Furthermore, the inner welding plate 110 extends to the outside of the vehicle body A-pillar structure 10 and faces the wheel 20 , thereby being able to transfer the welding structure 13 of the vehicle body A-pillar structure 10 to the outside of the vehicle, facilitating welding operations on the welding structure 13 .
[0048] like Figures 3 to 5 As shown, in some embodiments, the welded structure 13 formed by the inner welded plate 110 and the outer welded plate 120 is located outside the A-pillar structure 10 of the vehicle body and forms an obtuse angle structure with the collision zone facing the wheel 20 .
[0049] In this embodiment, the weld structure 13 and the collision zone form an obtuse angle facing the wheel 20. When the wheel 20 collides with the A-pillar structure 10, the A-pillar structure 10 pushes against the weld structure 13 to bend and deform toward the rear of the vehicle without causing forward compression or tearing of the weld structure 13. Furthermore, during this process, the weld structure 13 acts as an energy absorber and buffer, reducing the energy transferred from the wheel 20 to the collision zone of the A-pillar structure 10 and lowering the risk of compression damage to the A-pillar structure 10.
[0050] In addition, the welding structure 13 and the collision zone form an obtuse angle structure facing the wheel 20, which can also reduce the space occupied by the welding structure 13 in the width direction of the vehicle body and reduce the possibility of scratches caused by the welding structure 13 extending out of the vehicle.
[0051] Furthermore, a flexible protective cover is provided on the edge of the welding structure 13. The flexible protective cover can reduce the corrosion of the welding structure 13 on the one hand, and can also play a protective role to reduce the scratches on the part of the welding structure 13 extending outside the vehicle.
[0052] In some embodiments, the welded structure 13 formed by splicing the inner welded plate 110 and the outer welded plate 120 is located outside the vehicle body A-pillar structure 10 and is bent into a coiled structure.
[0053] In this embodiment, by setting the welding structure 13 as a winding structure, on the one hand, the structural strength of the welding structure 13 can be improved, and the phenomenon of the welding structure 13 being torn under the extrusion of the wheel 20 can be reduced; on the other hand, the stress concentration phenomenon of the welding structure 13 can be reduced, and the phenomenon of the welding structure 13 puncturing the tire of the wheel 20 under the extrusion of the wheel 20 can be reduced.
[0054] Specifically, the winding structure includes an arc-shaped winding and a rectangular winding, and the openings of the arc-shaped winding and the rectangular winding face away from the wheel 20 , thereby reducing the cracking and deformation of the winding opening caused by being squeezed by the wheel 20 .
[0055] like Figures 6 to 8 As shown, in some embodiments, a first clipping structure 112 corresponding to the collision zone is provided inside the A-pillar inner panel 11, and a second clipping structure 122 corresponding to the collision zone is provided inside the A-pillar outer panel 12. When the inner welding plate 110 and the outer welding plate 120 are in a spliced state, the first clipping structure 112 and the second clipping structure 122 are clipped to each other.
[0056] In this embodiment, the first clip structure 112 of the A-pillar inner panel 11 corresponds to the second clip structure 122 of the A-pillar outer panel 12 inside and outside, and the two cooperate to form a self-locking structure. When the A-pillar outer panel 12 is hit, the second clip structure 122 of the A-pillar outer panel 12 will engage and interlock with the first clip structure 112 of the A-pillar inner panel 11, thereby strengthening the connection reliability between the A-pillar inner panel 11 and the A-pillar outer panel 12, and further preventing the A-pillar inner panel 11 and the A-pillar outer panel 12 from cracking at the welding structure 13.
[0057] like Figures 6 to 8 As shown, in some embodiments, the first clamping structure 112 includes a first clamping plate 112 provided with a clamping slot, and the second clamping structure 122 includes a second clamping plate 122 provided with a hook that can extend into the clamping slot.
[0058] In this embodiment, the hook is set to an L-shaped structure, and the hook is set to fit with the gap of the clamping groove, so that during the splicing process of the A-pillar inner panel 11 and the A-pillar outer panel 12, the hook can smoothly extend into the clamping groove. When the A-pillar outer panel 12 is displaced by impact, the clamping groove can constrain the range of movement of the hook, thereby limiting the phenomenon of large displacement of the hook and the A-pillar outer panel 12.
[0059] like Figures 6 to 8 As shown, in some embodiments, the A-pillar inner panel 11 is configured as a hollow structure, and a first reinforcing rib 111 corresponding to the collision zone is provided inside the A-pillar inner panel 11, and / or the A-pillar outer panel 12 is configured as a hollow structure, and a second reinforcing rib 121 corresponding to the collision zone is provided inside the A-pillar outer panel 12.
[0060] In this embodiment, by providing the first reinforcing rib 111 and the second reinforcing rib 121 in a local area of the collision zone, the structural strength of the collision zone can be increased without excessively increasing the weight and cost of the vehicle body, thereby improving the small offset collision performance of the vehicle body.
[0061] Specifically, the first reinforcing ribs 111 and the second reinforcing ribs 121 are staggered along the height direction of the vehicle body A-pillar structure 10, so that the reinforcing ribs can cover the collision zone along the height direction of the vehicle body A-pillar structure 10, thereby improving the overall collision performance of the collision zone and reducing the uneven structural strength of the vehicle body A-pillar structure 10 in the collision zone.
[0062] In addition, the first reinforcing ribs 111 and the second reinforcing ribs 121 include honeycomb panels, plywood or L-shaped panels, and these structures all fall within the protection scope of the first reinforcing ribs 111 and the second reinforcing ribs 121 .
[0063] like Figures 6 to 8 As shown, in some embodiments, the bottom of the vehicle body A-pillar structure 10 forms an accommodating space for the vehicle body door sill 30, the first clip structure 112 and the second clip structure 122 are located above the vehicle body door sill 30, and the first reinforcement rib 111 and the second reinforcement rib 121 are located above the first clip structure 112 and the second clip structure 122.
[0064] In this embodiment, the first clip structure 112 of the A-pillar inner panel 11 corresponds to the second clip structure 122 of the A-pillar outer panel 12 inside and outside, and a self-locking structure is designed; when the A-pillar inner panel 11 or the A-pillar outer panel 12 is hit, the self-locking structure between the A-pillar inner panel 11 and the A-pillar outer panel 12 will cause the A-pillar inner panel 11 and the A-pillar outer panel 12 to engage and interlock together, thereby ensuring the connection stability between the A-pillar inner panel 11 and the A-pillar outer panel 12, and further preventing the A-pillar structure 10 of the vehicle body from cracking at the welding point.
[0065] The vehicle body A-pillar structure 10 provided in the present application is provided with two clip structures at the main path of small offset collision energy transmission (the junction of the front wheel cover and the vehicle body door sill 30). The two clip structures enhance the ability to withstand small offset collision energy transmission, thereby achieving the maximum absorption of small offset collision energy with the minimum weight and cost investment, thereby improving the small offset collision performance of the vehicle body.
[0066] like Figures 6 to 8 As shown, in some embodiments, the A-pillar inner panel 11 covers the projection of the wheel 20 onto the A-pillar inner panel 11 , the collision zone is located at the A-pillar inner panel 11 , and a reinforcement plate 14 covering the collision zone is provided outside the A-pillar inner panel 11 .
[0067] In this embodiment, a reinforcing plate 14 is provided in the main path of small offset collision energy transmission (collision area of the A-pillar inner panel 11), and the reinforcing plate 14 is used to enhance the ability to withstand small offset collision energy transmission, thereby achieving the maximum absorption of small offset collision energy with minimum weight and cost investment, thereby improving the small offset collision performance of the vehicle body.
[0068] Specifically, the reinforcing plate 14 can be set as a honeycomb plate, which can further reduce the weight and cost of the reinforcing plate 14, thereby improving the small offset collision performance of the vehicle body without increasing the weight and cost of the vehicle body too much.
[0069] like Figures 3 to 8 As shown, the second aspect of the present application provides a vehicle 100 , which includes a vehicle body and the vehicle body A-pillar structure 10 of the first aspect of the present application.
[0070] In this embodiment, the vehicle 100 described in the embodiment of the present application has all the technical effects of the vehicle body A-pillar structure 10 of the first aspect of the present application, which will not be described in detail here.
[0071] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
[0072] In addition, the embodiments of the present application only illustrate the key structures in the vehicle body A-pillar structure 10 that are closely related to the improvement points, and do not mean that the vehicle body A-pillar structure 10 only includes these structures. For example, the collision area of the vehicle body A-pillar structure 10 is also provided with a hollow energy absorption box. These embodiments all fall within the protection scope of the vehicle body A-pillar structure 10 of the embodiments of the present application, and the other structures of the vehicle body A-pillar structure 10 will not be described one by one here.
[0073] The above description is merely a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
