Description

Technical Field

[0001] The utility model belongs to the technical field of automobile collision safety, and in particular relates to a vehicle body pillar assembly applied to an automobile. Background Art

[0002] The car body structure is mainly made of sheet metal splicing and welding. The sheet metal splicing is a relatively weak area of ​​connection strength. When the car collides, the requirements for the connection strength of the sheet metal splicing are different due to different working conditions, speeds, environments, etc. In the process of side high-speed collision, the body pillar is the main load-bearing structural component.

[0003] Take the B-pillar as an example. As the main load-bearing structural component, the outer plate or inner cover plate of the B-pillar is often assembled separately to meet the stiffness requirements of different areas of the B-pillar. Due to various factors such as cost and process, the current sheet metal splicing is mainly completed by spot welding.

[0004] In some schemes, such as Figure 1a and Figure 1b As shown in FIG. 1 , when the upper cover plate 111′ and the lower cover plate 112′ of the B-pillar are spliced ​​together through the welding points, the side panel assembly is spliced ​​together with the B-pillar outer panel 120′ and the side panel outer panel 130′. In this way, four layers of panels appear in the area where the cover plates are spliced. Under the current traditional process conditions, the welding points of the four layers of panels cannot guarantee the welding quality. Therefore, the inner cover plate of the B-pillar and the outer panel are often spliced ​​in the splicing area (such as Figure 1b There is no weld connection in the dotted box area shown in the figure. In addition, the side working condition has a relatively high requirement for the connection strength of the B-pillar. As a weak point of connection, when hit from the side, the inner and outer panels will accelerate the concave trend in the splicing area because there is no weld connection between the inner and outer panels. The weld failure at the splicing point often leads to fracture (such as Figure 2 This situation greatly reduces the reliability of the B-pillar connection and creates uncontrollable risk of injury to occupant protection.

[0005] Therefore, the vehicle body pillar assembly in the prior art has the problem that the collision joint is prone to failure and fracture. Utility Model Content

[0006] The utility model aims to solve the problem that the vehicle body pillar assembly in the prior art is prone to failure and fracture at the collision joint.

[0007] In order to solve the above problems, the embodiment of the utility model provides a vehicle body pillar assembly, including an inner cover plate, a pillar outer plate and a side outer plate arranged in a stacked manner; the inner cover plate includes an upper cover plate and a lower cover plate which are overlapped and fixedly arranged end to end, the overlapped area of ​​the upper cover plate and the lower cover plate is the overlapped area, and the non-overlapped area of ​​the upper cover plate and the lower cover plate is the non-overlapped area; wherein,

By providing a avoidance hole in one of the sealing plates, when the upper and lower sealing plates are welded to the outer panel, even at the overlapping position of the lower sealing plate and the outer panel, the avoidance hole can avoid the other sealing plate, so that the staff can weld and fix the overlapping area of ​​the other sealing plate to the pillar outer panel and the side outer panel as a whole. In this way, multiple welding points can be present on the inner sealing plate, the pillar outer panel and the side outer panel, avoiding the problem that there are no welding points between the overlapping area of ​​the inner sealing plate and the pillar outer panel and the side outer panel, which affects the structural strength of the body pillar.

[0020] By adopting the above technical solution, the avoidance hole is formed on the flange, which is not only conducive to the formation of the welding point, but also does not affect the main structure of the sealing plate.

[0021] According to the vehicle body pillar assembly provided by the embodiment of the utility model, the avoidance hole is configured as an arc-shaped notch.

[0022] According to the vehicle body pillar assembly provided by the embodiment of the utility model, a plurality of first welding areas, second welding areas and third welding areas are provided, and the first welding areas, second welding areas and third welding areas are staggered in the height direction of the pillar outer panel.

[0026] The embodiment of the utility model further provides a car, which comprises a vehicle body pillar assembly of the structure above.

[0027] By adopting the above technical solution, since there are multiple welding points in the inner sealing plate, the outer plate of the pillar and the outer plate of the side panel of the vehicle body pillar assembly of the above structure, the problem of no welding points in the overlapping area of ​​the inner sealing plate affecting the structural strength of the vehicle body pillar is avoided. When a car adopts this vehicle body pillar assembly, it is safer in the event of a side collision, thereby ensuring that the vehicle body structure protects the collision safety of the occupants.

[0047] As the main load-bearing structural parts of a car, the body pillars need to provide a certain impact resistance to protect the occupants in the car when the car is hit from the side. In some solutions in the prior art, the body pillars usually include an inner cover plate, a pillar outer plate and a side outer plate, and the three are fixed by welding. The inner cover plate generally includes an upper cover plate and a lower cover plate, and the upper cover plate and the lower cover plate are overlapped end to end to form an inner cover plate. When the inner cover plate of this structure is welded to the pillar outer plate and the side outer plate, it can only be welded and fixed in the non-overlapping area of ​​the upper cover plate and the lower cover plate, and the overlapping area cannot be welded to the pillar outer plate and the side outer plate. This will cause the structural strength of the area on the body pillar located at the upper cover plate and the lower cover plate to be weak, and it is easy to fail and break when the car is hit from the side.

[0048] To this end, the utility model provides a vehicle body pillar assembly, which has welding points with the pillar outer panel and the side outer panel in the non-overlapping area and overlapping area of ​​the upper cover plate and the lower cover plate, so as to ensure the structural strength of each position of the vehicle body pillar and reduce the probability of failure and fracture when the vehicle is hit from the side.

[0049] It should be understood that the vehicle body pillar assembly in the present invention mainly refers to the B-pillar structure of the vehicle. The B-pillar of the vehicle refers to the pillar located between the driver's side window glass and the rear side window glass. It is the pillar for fixing the seat belt behind the driver's side and connects the front and rear doors. In terms of safety, the strength of the B-pillar structure of the vehicle directly affects the performance of the vehicle in a collision.

[0050] Of course, the structure of this body pillar assembly can also be applied to other body splicing structures, such as some side beam lap structures.

[0051] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention is further described in detail below by taking the B-pillar of an automobile as an example in conjunction with the accompanying drawings.

[0052] The embodiment of the utility model provides a vehicle body pillar assembly, see Figures 3 to 6 , including an inner cover plate 100, a pillar outer panel 200 and a side outer panel 300 arranged in a stacked manner; the inner cover plate 100 includes an upper cover plate 110 and a lower cover plate 120 which are overlapped and fixedly arranged end to end, the overlapped area of ​​the upper cover plate 110 and the lower cover plate 120 is an overlapped area A, and the non-overlapped area of ​​the upper cover plate 110 and the lower cover plate 120 is a non-overlapped area B; the vehicle body pillar assembly also includes a height direction H of the pillar outer panel 200 (see Figure 6 ) are sequentially arranged on a first welding area 410, a second welding area 420 and a third welding area 430.

[0053] It should be understood that the first welding area 410 , the second welding area 420 , and the third welding area 430 refer to areas filled with solder during welding.

[0054] The first welding area 410, the second welding area 420 and the third welding area 430 are described below in combination with the structures of the inner sealing plate 100, the pillar outer plate 200 and the side outer plate 300:

[0055] See also Figure 6 The first welding area 410 is configured to integrally weld and fix the non-overlapping area B of the upper cover plate 110 , the corresponding pillar outer panel 200 , and the side outer panel 300 .

[0056] The overlapping area A of one of the upper covering plate 110 and the lower covering plate 120 is located on the side of the overlapping area A of the other covering plate away from the pillar outer panel 200, one of the covering plates is provided with an avoidance hole 130, and the second welding area 420 is configured to weld and fix the portion of the overlapping area A of the other covering plate corresponding to the avoidance hole 130, the corresponding pillar outer panel 200 and the side outer panel 300 as a whole.

[0057] It should be understood that there is no limit to the setting method of the upper cover plate 110 and the lower cover plate 120. The overlapping area A of the upper cover plate 110 can be located on the side of the overlapping area A of the lower cover plate 120 away from the pillar outer panel 200, or the overlapping area A of the lower cover plate 120 can be located on the side of the overlapping area A of the upper cover plate 110 away from the pillar outer panel 200.

[0058] In one embodiment, when the overlapping area A of the lower covering plate 120 is located on the side of the overlapping area A of the upper covering plate 110 away from the pillar outer panel 200, the lower covering plate 120 is provided with an avoidance hole 130, and the second welding area 420 is configured as follows: the portion of the overlapping area A of the upper covering plate 110 corresponding to the avoidance hole 130, the corresponding pillar outer panel 200 and the side outer panel 300 are integrally welded and fixed.

[0059] In other alternative embodiments, when the overlapping area A of the upper cover plate 110 is located on the side of the overlapping area A of the lower cover plate 120 away from the pillar outer panel 200, the upper cover plate 110 is provided with an avoidance hole 130, and the second welding area 420 is configured as follows: the portion of the overlapping area A of the lower cover plate 120 corresponding to the avoidance hole 130, the corresponding pillar outer panel 200 and the side outer panel 300 are welded and fixed as a whole.

[0060] The third welding area 430 is configured to integrally weld and fix the non-overlapping area B of the lower cover plate 120 , the corresponding pillar outer panel 200 , and the side outer panel 300 .

[0061] The vehicle body pillar assembly provided by the utility model has a first welding area 410, a second welding area 420 and a third welding area 430 sequentially arranged in the height direction H of the pillar outer panel 200; the three welding areas can enhance the connection strength between the inner cover plate 100, the pillar outer panel 200 and the side outer panel 300.

[0062] Specifically, see Figure 6 , the first welding area 410 can weld and fix the non-overlapping area B of the upper sealing plate 110, the corresponding pillar outer panel 200 and the side outer panel 300 as a whole, and the third welding area 430 can weld and fix the non-overlapping area B of the lower sealing plate 120, the corresponding pillar outer panel 200 and the side outer panel 300 as a whole. By providing the avoidance hole 130 in one of the sealing plates, when the upper sealing plate 110 and the lower sealing plate 120 are welded to the outer panel, even at the overlapping position of the lower sealing plate 120 and the outer panel, the avoidance hole 130 can avoid the other sealing plate, so that the staff can weld and fix the overlapping area A of the other sealing plate to the pillar outer panel 200 and the side outer panel 300 as a whole. In this way, multiple welding points can be present in the inner sealing plate 100, the pillar outer panel 200 and the side outer panel 300, avoiding the problem that the overlapping area A of the inner sealing plate 100 has no welding points and affects the structural strength of the vehicle body pillar. In particular, it can reduce the probability of failure and fracture in the overlapping area of ​​the body pillar during a car collision.

[0063] The inner sealing plate 100 is described below. As described above, the inner sealing plate 100 includes an upper sealing plate 110 and a lower sealing plate 120. When the upper sealing plate 110 and the lower sealing plate 120 are connected:

[0064] See also Figure 4 and Figure 6 The vehicle body pillar assembly further includes a sealing plate welding area 440 , and the sealing plate welding area 440 is configured to integrally weld and fix the overlapping area A of the upper sealing plate 110 and the overlapping area A of the lower sealing plate 120 .

[0065] It should be understood that the sealing plate welding area 440 refers to the area filled with Korean material between the overlapping area A of the upper sealing plate 110 and the overlapping area A of the lower sealing plate 120.

[0066] By setting the sealing plate welding area 440, not only the connection strength between the upper sealing plate 110 and the lower sealing plate 120 can be improved, but also the structural integrity between the upper sealing plate 110, the lower sealing plate 120 and the pillar outer panel 200 and the side outer panel 300 can be improved.

[0067] Furthermore, at least two sealing plate welding areas 440 are provided, and in the height direction H of the pillar outer panel 200 , the second welding area 420 is located between the two sealing plate welding areas 440 .

[0068] By providing at least two sealing plate welding areas 440 and locating the second welding area 420 between the two sealing plate welding areas 440 , not only the overall structural strength of the vehicle body pillar assembly can be improved, but also stress dispersion can be facilitated.

[0069] It should be understood that there is no limit to the number of sealing plate welding areas 440 , and it can be any number such as two, three, or four.

[0070] See also Figure 6 When two sealing plate welding areas 440 are provided, the second welding area 420 is located between the two sealing plate welding areas 440 .

[0071] When three sealing plate welding areas 440 are provided, two sealing plate welding areas 440 may be provided on one side of the second welding area 420 , and one sealing plate welding area 440 may be provided on the other side.

[0072] When four sealing plate welding areas 440 are provided, two sealing plate welding areas 440 may be provided on one side of the second welding area 420 , and two sealing plate welding areas 440 may be provided on the other side.

[0073] It should be understood that, for the first welding area 410, the second welding area 420, the third welding area 430, and the sealing plate welding area 440 mentioned above, there is no limit on the number of them, and the specific number should be determined according to the column size used in the specific vehicle model.

[0074] In one embodiment, a plurality of the first welding area 410 , the second welding area 420 , and the third welding area 430 are provided, and the first welding area 410 , the second welding area 420 , and the third welding area 430 are staggered in the height direction H of the pillar outer panel 200 .

[0075] By distributing the first welding area 410 , the second welding area 420 , and the third welding area 430 in a staggered manner in the height direction H of the pillar outer panel 200 , stress concentration when the vehicle body pillar assembly is subjected to force can be further avoided, which is beneficial to the structural stability of the vehicle body pillar assembly.

[0076] See also Figures 3 to 5 , the arrangement of the avoidance hole 130 is described in detail below:

[0077] In one embodiment, the avoidance holes 130 are arranged in pairs at both side edges of one of the inner sealing plates 100 in the width direction of the inner sealing plate 100 .

[0078] Furthermore, a flange 121 is formed on an edge of one of the sealing plates in the width direction of the inner sealing plate 100 , and the avoidance hole 130 is formed on the flange 121 .

[0079] By forming the avoidance hole 130 on the flange 121, it is not only beneficial to form the welding point, but also does not affect the main structure of the sealing plate.

[0080] Furthermore, the structure of the avoidance hole 130 is not limited, for example, it can be set as an arc-shaped notch, a circular notch, etc.

[0081] In one embodiment, the avoidance hole 130 is configured as an arc-shaped notch opened on the flange 121 .

[0082] In other alternative embodiments, the avoidance hole 130 is configured as a circular notch opened on the flange 121 .

[0083] See also Figures 3 to 5 , taking the following sealing plate 120 provided with the avoidance hole 130 as an example, the setting method of the avoidance hole 130 is described in detail:

[0084] See also Figure 3 to Figure 4 As shown, the avoidance holes 130 are arranged in pairs at the edge positions of both sides of the lower sealing plate 120 in the width direction of the inner sealing plate 100 .

[0085] Specifically, a flange 121 is formed on the edge of the lower sealing plate 120 in the width direction of the inner sealing plate 100, and the avoidance hole 130 is set to be an arc-shaped notch formed on the flange 121. The avoidance hole 130 can also be a U-shaped incision formed by cutting. The avoidance hole 130 can be used to leave a welding space when the upper sealing plate 110 is welded to the column outer plate 200. The structure has a simple process, low cost, and little impact on welding efficiency.

[0086] When the vehicle body pillar assembly provided by the utility model is welded, the upper sealing plate 110 and the lower sealing plate 120 are overlap-welded to form the inner sealing plate 100 , and then the inner sealing plate 100 and the side outer plate 300 are respectively welded to the two sides of the pillar outer plate 200 .

[0087] For details, see Figure 6 When the upper sealing plate 110 and the lower sealing plate 120 are overlap-welded, the upper sealing plate 110 and the lower sealing plate 120 are welded and fixed by filling solder in the sealing plate welding area 440 .

[0088] When the inner cover plate 100 is welded to the pillar outer panel 200, the first welding area 410 is formed between the non-overlapping area B of the upper cover plate 110 and the pillar outer panel 200. By filling solder in the first welding area 410, the non-overlapping area B of the upper cover plate 110 is welded and fixed to the pillar outer panel 200.

[0089] The first welding area 410 may also refer to the space between the non-overlapping area B of the upper cover plate 110 and the pillar outer panel 200, and between the pillar outer panel 200 and the side outer panel 300. The non-overlapping area B of the upper cover plate 110 is welded and fixed to the pillar outer panel 200 by filling solder between the non-overlapping area B of the upper cover plate 110 and the pillar outer panel 200, and the pillar outer panel 200 is welded and fixed to the side outer panel 300 by filling solder between the pillar outer panel 200 and the side outer panel 300.

[0090] The second welding area 420 refers to the space between the overlapping area of ​​the upper sealing plate 110 and the lower sealing plate 120 in the inner sealing plate 100 and the pillar outer panel 200. By filling solder in the second welding area 420, the overlapping area of ​​the upper sealing plate 110 and the lower sealing plate 120 is welded and fixed to the pillar outer panel 200.

[0091] The second welding area 420 may also refer to the space between the overlapping area of ​​the upper sealing plate 110 and the lower sealing plate 120 in the inner sealing plate 100 and the pillar outer panel 200, and between the pillar outer panel 200 and the side outer panel 300.

By filling solder between the pillar outer panel 200 and the side outer panel 300, the pillar outer panel 200 and the side outer panel 300 are welded and fixed to the side outer panel 300.

[0092] It should be understood that when the upper sealing plate 110 is located close to the pillar outer panel 200, the second welding area 420 refers to the space between the overlapping area of ​​the upper sealing plate 110 in the inner sealing plate 100 and the pillar outer panel 200, and the overlapping area of ​​the upper sealing plate 110 and the lower sealing plate 120 is welded and fixed to the pillar outer panel 200 by filling solder in the space between the overlapping area of ​​the upper sealing plate 110 in the inner sealing plate 100 and the pillar outer panel 200.

[0093] The third welding area 430 is formed between the non-overlapping region B of the lower sealing plate 120 and the pillar outer panel 200 . Solder is filled in the third welding area 430 so that the non-overlapping region B of the lower sealing plate 120 and the pillar outer panel 200 are welded and fixed.

[0094] The third welding area 430 may also refer to the space between the non-overlapping area B of the lower cover plate 120 and the pillar outer panel 200, and between the pillar outer panel 200 and the side outer panel 300.
