Description

Technical Field

[0001] This application relates to the field of vehicle parts technology, and in particular to a vehicle C-pillar connector connection structure, a frame, and a vehicle. Background Technology

[0002] Vehicle chassis development has always been a consideration for vehicle designers. As more and more companies enter the vehicle industry, competition in chassis is becoming increasingly fierce, and people are paying more and more attention to the strength and stability of the chassis.

[0003] The existing C-pillar connector for vehicle frames includes the C-pillar body, C-pillar reinforcement plate, rear wheel arch plate, and wheel arch connecting plate. However, due to structural layout constraints, the weld points at the wheel arch connecting plate are inaccessible, and the C-pillar reinforcement plate is too small, lacking space for welding through holes. This makes welding the wheel arch connecting plate inconvenient, reducing connection strength and causing overall structural instability.

[0004] Therefore, it needs to be improved. Summary of the Invention

[0005] The purpose of this application is to provide a vehicle C-pillar joint connection structure, frame, and vehicle with good layout space and improved connection strength.

[0006] This application provides a vehicle C-pillar connector connection structure, including a C-pillar component and a rear wheel arch. The C-pillar component includes a C-pillar plate and a C-pillar reinforcing plate, with the reinforcing plate connected to the side of the C-pillar plate away from the roof. The C-pillar plate has a welding through hole for a welding torch to enter. The rear wheel arch includes an outer wheel arch plate and a connecting plate, with the connecting plate connected to the side of the C-pillar plate away from the front of the vehicle and to the outer wheel arch plate away from the roof. The connection between the connecting plate and the outer wheel arch plate has a dividing seam, located between the welding through hole and the reinforcing plate.

[0007] Furthermore, the C-pillar reinforcing plate has a top end facing the C-pillar plate, and the distance between the dividing seam and the top end of the reinforcing plate is greater than the distance between the dividing seam and the welding through hole.

[0008] Furthermore, the C-pillar component also includes a sill back panel, which is connected to the side of the C-pillar reinforcement plate near the front of the vehicle; the rear wheel arch also includes a wheel arch inner panel, which is connected to the inner side of the wheel arch outer panel; the wheel arch inner panel is connected to the sill back panel, the wheel arch connecting plate is connected to the wheel arch inner panel, and the C-pillar reinforcement plate is connected to the wheel arch connecting plate.

[0009] Furthermore, the inner wheel arch panel includes a first inner panel and a second inner panel connected to the first inner panel. The first inner panel extends toward the rear door sill plate, and the second inner panel extends away from the rear door sill plate. A first connecting plate is connected to the inner side of the wheel arch connecting plate, and the first connecting plate extends toward the second inner panel. The first inner panel is connected to the rear door sill plate, and the first connecting plate is connected to the second inner panel.

[0010] Furthermore, a second connecting plate is connected to the outer side of the wheel arch connecting plate. The second connecting plate extends away from the C-pillar reinforcing plate and is connected to the wheel arch connecting plate in an L-shape. A first extension plate extending toward the second connecting plate is connected to the C-pillar reinforcing plate and is connected to the second connecting plate.

[0011] Furthermore, a first limiting plate is connected between the first extension plate and the C-pillar reinforcing plate, and the first limiting plate is connected to the second connecting plate in an L-shape; the first limiting plate is located between the C-pillar reinforcing plate and the wheel arch connecting plate.

[0012] Furthermore, the sill rear end plate includes a rear end plate body and a rear end plate flange connected to the rear end plate body, the rear end plate flange extending away from the wheel arch connecting plate; a second extension plate extending toward the rear end plate flange is connected to the C-pillar reinforcing plate, the second extension plate being connected to the rear end plate flange.

[0013] Furthermore, a second limiting plate is connected between the second extension plate and the C-pillar reinforcing plate, and the second limiting plate and the second extension plate are connected in an L-shape; the second limiting plate is located between the C-pillar reinforcing plate and the rear end plate body.

[0014] The technical solution provided in this application provides a vehicle frame, including the vehicle C-pillar joint connection structure described in any of the above claims.

[0015] The present application provides a vehicle including the aforementioned chassis.

[0016] The above technical solution has the following beneficial effects: The proposed C-pillar joint connection structure for vehicles includes a rear wheel arch consisting of an outer wheel arch panel and a connecting plate, with the dividing line between them close to a welding through-hole. This allows the welding torch to be inserted into the welding through-hole to weld the connecting plate, ensuring the weld point is accessible and strengthening the connection between the connecting plate and other components. This more rational spatial arrangement of the C-pillar joint connection structure results in a more robust assembled structure, ensuring the structural stability of the frame and improving vehicle quality.

Detailed Implementation

[0018] The specific embodiments of this application will be further described below with reference to the accompanying drawings.

[0019] It is readily understood that, based on the technical solution of this application, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of this application. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this application and should not be considered as the entirety of this application or as limitations or restrictions on the technical solution of the application.

[0020] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0021] like Figure 1-5 The image shows a vehicle C-pillar connector connection structure 10 provided in an embodiment of this application, including a C-pillar member 1 and a rear wheel arch 2. The C-pillar member 1 includes a C-pillar plate 11 and a C-pillar reinforcing plate 12, with the C-pillar reinforcing plate 12 connected to the side of the C-pillar plate 11 away from the roof.

[0022] The C-column plate 11 is provided with a welding through hole 111 for the welding torch to be inserted.

[0023] The rear wheel arch 2 includes an outer wheel arch panel 21 and a wheel arch connecting plate 22. The outer wheel arch panel 21 is connected to the C-pillar panel 11 on the side away from the front of the vehicle, and the wheel arch connecting plate 22 is connected to the outer wheel arch panel 21 on the side away from the roof of the vehicle.

[0024] The connection between the wheel cover connecting plate 22 and the outer plate 21 of the wheel cover has a dividing seam 23, which is located between the welding through hole 111 and the C-pillar reinforcing plate 12.

[0025] The C-pillar joint connection structure 10 is a component of the vehicle frame, and its connection performance affects the structural strength of the entire vehicle frame.

[0026] For ease of explanation, the front of the vehicle is considered the front, the rear is considered the rear, the width of the vehicle is considered the left-right direction, and the height of the vehicle is considered the up-down direction.

[0027] The vehicle C-pillar connector structure 10 includes a C-pillar member 1 and a rear wheel arch 2, with the C-pillar member 1 connected to the front of the rear wheel arch 2. The C-pillar member 1 includes a C-pillar plate 11 and a C-pillar reinforcing plate 12, with the reinforcing plate 12 connected below the C-pillar plate 11. After connection, a connecting seam is formed between the upper end of the reinforcing plate 12 and the lower end of the C-pillar plate 11. A welding through-hole 111 is provided on the C-pillar plate 11, penetrating the C-pillar plate 11, allowing a welding torch to be inserted for welding during assembly.

[0028] The rear wheel arch 2 includes an outer wheel arch plate 21 and a connecting plate 22. The outer wheel arch plate 21 is connected to the rear of the C-pillar plate 11, and the connecting plate 22 is connected to the lower part of the outer wheel arch plate 21. The upper end of the connecting plate 22 connects to the lower end of the outer wheel arch plate 21 to form a dividing seam 23. The dividing seam 23 is located between the welding through hole 111 and the C-pillar reinforcing plate 12, that is, between the welding through hole 111 and the connecting seam.

[0029] This design allows a larger portion of the upper part of the wheel cover connecting plate 22 to be closer to the welding through hole 111, making the weld point accessible. This allows the welding torch to fully weld the wheel cover connecting plate 22 after being inserted through the welding through hole 111, improving the connection strength of the wheel cover connecting plate 22 and resulting in a stronger and more robust structure after assembly.

[0030] It should be noted that the distance between the dividing seam 23 and the welding through hole 111 refers to the vertical distance between the dividing seam 23 and the welding through hole 111. Similarly, the distance between the dividing seam 23 and the C-pillar reinforcing plate 12 also refers to the vertical distance.

[0031] In one embodiment, such as Figure 1 and Figure 3-5As shown, the C-pillar reinforcing plate 12 has a top end 121 facing the C-pillar plate 11, and the distance between the dividing seam 23 and the top end 121 is greater than the distance between the dividing seam 23 and the welding through hole 111.

[0032] Specifically, the upper end of the C-pillar reinforcing plate 12 is the reinforcing plate top 121, and a connecting seam is formed between the reinforcing plate top 121 and the C-pillar plate 11. The distance between the dividing seam 23 and the connecting seam is greater than the distance between the dividing seam 23 and the welding through hole 111. This arrangement allows the wheel arch connecting plate 22 to be closer to the welding through hole 111, thereby enabling welding over a larger area.

[0033] In one embodiment, such as Figure 1-3 and Figure 5-7 As shown, the C-pillar component 1 also includes a sill back panel 13, which is connected to the C-pillar reinforcement plate 12 on the side near the front of the vehicle. The rear wheel arch 2 also includes a wheel arch inner panel 24, which is connected to the inner side of the wheel arch outer panel 21. The wheel arch inner panel 24 is connected to the sill back panel 13, the wheel arch connecting plate 22 is connected to the wheel arch inner panel 24, and the C-pillar reinforcement plate 12 is connected to the wheel arch connecting plate 22.

[0034] Specifically, the C-pillar component 1 also includes a sill back panel 13, which is located at the front end of the C-pillar reinforcing plate 12. The rear wheel arch 2 also has an inner wheel arch panel 24, which is located inside the outer wheel arch panel 21, and the surface of the inner wheel arch panel 24 facing the outer wheel arch panel 21 is connected to the outer wheel arch panel 21. After the C-pillar component 1 and the rear wheel arch 2 are assembled, the inner wheel arch panel 24 is connected to the sill back panel 13, the sill back panel 13 is connected to the C-pillar reinforcing plate 12, the C-pillar reinforcing plate 12 is connected to the wheel arch connecting plate 22, and the wheel arch connecting plate 22 is connected to the inner wheel arch panel 24. This arrangement results in a more robust connection and a more stable structure.

[0035] In one embodiment, as shown in the figure, the wheel arch inner plate 24 includes a first inner plate 241 and a second inner plate 242 connected to the first inner plate 241. The first inner plate 241 extends toward the rear door sill plate 13, and the second inner plate 242 extends away from the rear door sill plate 13. A first connecting plate 221 is connected to the inner side of the wheel arch connecting plate 22, and the first connecting plate 221 extends toward the second inner plate 242. The first inner plate 241 is connected to the rear door sill plate 13, and the first connecting plate 221 is connected to the second inner plate 242.

[0036] Specifically, the inner panel 24 of the wheel arch includes a first inner panel 241 and a second inner panel 242. The first inner panel 241 is connected to the second inner panel 242. The first inner panel 241 extends toward the rear door stop 13 of the door sill, and the second inner panel 242 extends away from the rear door stop 13 of the door sill. The included angle between the two is an obtuse angle.

[0037] The wheel arch connecting plate 22 has an outer side and an inner side. A first connecting plate 221 is connected to the inner side of the wheel arch connecting plate 22, extending towards the second inner plate 242, i.e., extending rearward. When the sill rear end plate 13, the wheel arch inner plate 24, and the wheel arch connecting plate 22 are connected, the first inner plate 241 is connected to the sill rear end plate 13, and the second inner plate 242 is connected to the first connecting plate 221. The first connecting plate 221 increases the contact area with the wheel arch inner plate 24, making the connection between the wheel arch connecting plate 22 and the wheel arch inner plate 24 more secure.

[0038] In one embodiment, such as Figure 7-10 As shown, a second connecting plate 222 is connected to the outer side of the wheel arch connecting plate 22. The second connecting plate 222 extends away from the C-pillar reinforcing plate 12, and the connection between the second connecting plate 222 and the wheel arch connecting plate 22 is L-shaped. A first extension plate 122 extending toward the second connecting plate 222 is connected to the C-pillar reinforcing plate 12, and the first extension plate 122 is connected to the second connecting plate 222.

[0039] Specifically, a second connecting plate 222 is connected to the outer side of the wheel arch connecting plate 22. The second connecting plate 222 extends rearward, forming an L-shape with the wheel arch connecting plate 22. The C-pillar reinforcing plate 12 is located between the sill rear end plate 13 and the wheel arch connecting plate 22. A first extension plate 122 is connected to the end of the C-pillar reinforcing plate 12 closest to the wheel arch connecting plate 22. The first extension plate 122 extends to the second connecting plate 222 and connects with it. The cooperation between the second connecting plates 222 increases the connection strength between the C-pillar reinforcing plate 12 and the wheel arch connecting plate 22, making the connection more secure.

[0040] In one embodiment, such as Figure 7-10 As shown, a first limiting plate 123 connects the first extension plate 122 and the C-pillar reinforcing plate 12, and the first limiting plate 123 is connected to the second connecting plate 222 in an L-shape. The first limiting plate 123 is located between the C-pillar reinforcing plate 12 and the wheel arch connecting plate 22.

[0041] Specifically, the first extension plate 122 is connected to the C-pillar reinforcement plate 12 via a first limiting plate 123. The first limiting plate 123 and the first extension plate 122 are connected in an L-shape and are located between the wheel arch connecting plate 22 and the C-pillar reinforcement plate 12. The first limiting plate 123 and the first extension plate 122 form a first limiting space, within which a portion of the wheel arch connecting plate 22 is located and can be limited and blocked by the first limiting plate 123. This facilitates positioning and installation.

[0042] In one embodiment, such as Figure 7-10As shown, the sill rear end plate 13 includes a rear end plate body 131 and a rear end plate flange 132 connected to the rear end plate body 131. The rear end plate flange 132 extends away from the wheel arch connecting plate 22. A second extension plate 124 extending toward the rear end plate flange 132 is connected to the C-pillar reinforcement plate 12. The second extension plate 124 is connected to the rear end plate flange 132.

[0043] Specifically, the rear door sill plate 13 includes a rear door sill body 131 and a rear door sill flange 132. The rear door sill body 131 is connected to the inner wheel arch plate 24, and the rear door sill flange 132 is connected to the side of the rear door sill body 131 away from the wheel arch connecting plate 22. The rear door sill flange 132 extends in a direction away from the wheel arch connecting plate 22 and is connected to the rear door sill body 131 in an L-shape.

[0044] A second extension plate 124 is connected to the side of the C-pillar reinforcement plate 12 away from the wheel arch connecting plate 22. The second extension plate 124 extends toward and connects to the rear end plate flange 132. The connection between the second extension plate 124 and the rear end plate flange 132 enhances the connection strength between the C-pillar reinforcement plate 12 and the sill rear end plate 13, making the connection between the two more secure.

[0045] In one embodiment, such as Figure 7-10 As shown, a second limiting plate 125 connects the second extension plate 124 and the C-pillar reinforcing plate 12, and the second limiting plate 125 and the second extension plate 124 are connected in an L-shape. The second limiting plate 125 is located between the C-pillar reinforcing plate 12 and the rear end plate body 131.

[0046] Specifically, the second extension plate 124 is connected to the C-pillar reinforcement plate 12 via the second limiting plate 125. The connection between the second limiting plate 125 and the second extension plate 124 forms an L-shape, creating a second limiting space. Part of the sill back panel 13 is located within the second limiting space and can be blocked and limited by the second limiting plate 125, thus facilitating installation.
