Abstract
Description
Technical Field
[0001] The utility model relates to a car body, and specifically provides a car body and a vehicle. Background Art
[0002] At present, the triangular windows of many models extend to the rear end of the side panel of the vehicle body, forming a step-shaped step on the side panel. The flange length of the side panel outer panel at the step position is very short, which cannot meet the welding width requirement. As a result, the distance between the connection points of the side panel and the water trough unit in the step transition area is too long. During the painting and baking process, the sheet metal will produce thermal deformation, and the side panel and the water trough unit step transition position will produce relative displacement, causing the painted PVC (polyvinyl chloride) to crack. This leads to a lot of rework time in the subsequent production process, reducing production efficiency. In order to solve the PVC cracking problem, past experience has been to increase the connection stability of the side panel and the water trough unit step transition position by adding arc welding. Arc welding has secondary problems such as spatter, and the appearance is not beautiful and requires polishing, which increases a lot of work hours. Therefore, the existing technology has not solved the above technical problems well.
[0003] Accordingly, the art requires a new vehicle body structure to solve the above problems. Utility Model Content
[0004] The utility model aims to solve the above technical problems, that is, to solve the problem in the prior art that the welding effect between the side panel of the vehicle body and the water flow channel is poor and easy to deform, which in turn causes the coated PVC to be easy to crack.
[0005] In a first aspect, the utility model provides a vehicle body, which includes at least a side panel and a water trough unit, wherein the side panel includes a window mounting portion, a transition portion and a flange portion, the transition portion is arranged between the flange portion and the window mounting portion so that the flange portion is bent relative to the window mounting portion, and the water trough unit includes a first flange, a second flange and a third flange, wherein the first flange is connected to the flange portion with a first welding point, the second flange is connected to the transition portion with a second welding point, and the third flange is connected to the window mounting portion with a third welding point, and the first welding point, the second welding point and the third welding point form a triangular welding area.
[0006] In a specific embodiment of the vehicle body, the vehicle body further includes a paint protection layer, and the paint protection layer is provided at the corresponding intersection of the water trough unit and the side panel.
[0007] In a specific embodiment having the above vehicle body, the transition portion is configured as a step structure.
[0008] In a specific embodiment of the vehicle body, the first flange is welded to the flange portion at least two welding points; and / or
[0009] The third flange is connected to the vehicle window mounting portion via at least two welding points.
[0010] In a specific embodiment having the above vehicle body, the shape of the second flange matches the stepped structure of the transition portion so that the second flange fits the transition portion.
[0011] In a specific embodiment having the above vehicle body, the water trough unit is provided with a groove, and the first flange, the second flange and the third flange are arranged at intervals on the edge of the groove along the direction of water flow.
[0012] In a specific embodiment of the vehicle body, a plurality of convex tie bars are provided at the bottom of the groove, and the width of the convex tie bars is smaller than the width of the groove.
[0013] In a specific embodiment of the vehicle body, the vehicle window mounting portion is provided with at least a triangular window mounting area, and the third flange is close to the triangular window mounting area to be connected to the vehicle window mounting portion.
[0014] In a specific embodiment of the vehicle body, a fixing hole is provided on the third flange, and the paint protective layer is bent to bypass the fixing hole.
[0015] The present invention also provides a vehicle, which includes the vehicle body according to any one of the above solutions.
[0016] Under the condition of adopting the above-mentioned technical scheme, the utility model discloses a vehicle body, which improves and optimizes the welding structure between the side panel and the water trough unit of the vehicle body. Specifically, the water trough unit is provided with a plurality of flange structures at different positions, which are welded to different parts of the side panel to form a welding structure different from that in the prior art, wherein the first flange of the water trough unit is connected to the flange part of the vehicle body through a first welding point, the second flange is connected to the transition part through a second welding point, and the third flange is connected to the window mounting part through a third welding point. The first welding point, the second welding point and the third welding point form a triangular welding area structure. Through the second welding point, the distance between the first welding point and the third welding point is shortened, so that the connection between the side panel and the water trough unit is more stable. Even when painting and baking, the sheet metal will not undergo large deformation, resulting in cracking of the painted PVC, thereby improving the reliability and efficiency of production. Without affecting the overall appearance of the vehicle body, the problem of poor welding effect and easy deformation between the side panel and the water trough of the vehicle body in the prior art, which leads to easy cracking of the painted PVC, is solved.

This is for ease of description only and does not indicate or imply that the relevant devices or components must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, ordinal numbers such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0024] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "installation" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0025] Furthermore, in order to more clearly demonstrate the core technical solution of the present invention, the description of the well-known structures of the vehicle body is omitted in the following description. However, this omission is only for the convenience of description and does not mean that the vehicle body can be without these structures.
[0026] like Figure 1-3As shown, the utility model proposes a vehicle body, which at least includes a side panel 1 and a water trough unit 2, wherein the side panel 1 includes a window mounting portion 3, a transition portion 4 and a flange portion 5, the transition portion 4 is arranged between the flange portion 5 and the window mounting portion 3 so that the flange portion 5 is bent relative to the window mounting portion 3, and the water trough unit 2 includes a first flange 6, a second flange 7 and a third flange 8, wherein the first flange 6 is connected to the flange portion 5 by a first welding point 9, the second flange 7 is connected to the transition portion 4 by a second welding point 10, and the third flange 8 is connected to the window mounting portion 3 by a third welding point 11, and the first welding point 9, the second welding point 10 and the third welding point 11 form a triangular welding area.
[0027] In this embodiment, the vehicle body includes various components, including a main body, functional components, and accessories. To more clearly illustrate the improvements of the present invention, the following is a detailed description of the connection between the side panel 1 and the water trough unit 2. Specifically, the improvement lies in the connection structure between the water trough unit 2 and the side panel 1. Referring to the connection structure between the water trough unit 2 and the side panel 1 in the prior art, the first flange 6 of the water trough unit 2 is connected to the flange portion 5 of the vehicle body via a first weld point, and the third flange 8 is connected to the window mounting portion 3 via a third weld point 11. However, due to the bend between the flange portion and the window mounting portion 3 caused by the transition portion 4 of the vehicle body, the distance between the first weld point 9 and the third weld point 11 at the connection between the side panel 1 and the water trough unit 2 is too long. During the coating and baking process, the sheet metal will thermally deform, causing relative displacement between the side panel 1 and the water trough unit 2 at the corresponding positions of the transition portion 4, resulting in cracking of the PVC coating at the connection.
[0028] In view of the above problems, in this embodiment, a flange, namely a second flange 7, is added to the water trough unit 2. The second flange 7 corresponds to the position of the transition part 4 on the vehicle body, and the second flange 7 is connected to the transition part 4 of the vehicle body through a second welding point 10. Then, the flange part 5 of the vehicle body and the transition part 4 to the window mounting part 3 all have welding points with the water trough unit 2. The second welding point 10 is between the first welding point 9 and the third welding point 11, shortening the distance between the welding points. At the same time, the first welding point 9, the second welding point 10 and the third welding point 11 also form a triangular welding area, thereby improving the stability of the connection. Even during painting and baking, the sheet metal will not undergo large deformation, causing the painted PVC to crack, thereby improving the reliability and efficiency of production.
[0029] It should be noted that the connection structure between the side panel 1 and the water trough unit 2 can be applied to various vehicle body structures as long as they are prone to sheet metal deformation. At the same time, the corresponding vehicle body can also be applied to various types of vehicles. This is not restrictive. For example, new energy vehicles, commercial vehicles and other models can be applied. The above is only an example and does not limit the scope of protection of the present utility model.
[0030] Based on the above embodiment, after the side panel 1 is welded to the water trough unit 2, a coating protective layer 12 is provided at the intersection of the water trough unit 2 and the side panel 1. The coating protective layer 12 is made of PVC (polyvinyl chloride) material to protect the gap at the connection.
[0031] On the basis of the above embodiments, the transition portion 4 is used to make the flange portion 5 and the window mounting portion 3 have a bent structure. The flange portion 5 can be used as the exposed part of the vehicle body, and the window mounting portion 3 can also be provided with other functional components of the vehicle body. The structural form of the transition portion 4 can take various forms. In this embodiment, a step structure is adopted. By adopting the step structure, the structural strength of the side panel 1 is higher. Although a step structure is adopted in this embodiment, the transition portion 4 of the side panel 1 can also be designed into other structures according to actual needs. This is not restrictive.
[0032] On the basis of the above embodiment, the number of welding points between the first flange 6 and the flange portion 5 is set to at least two. In the above embodiment, the first welding point 9 has been set as the connection point, and other welding points can also be set to increase the welding strength. For example, the first welding point 9 is close to the side of the transition portion 4, and a fourth welding point can also be set on the first flange 6 on the side away from the transition portion 4 to increase the strength.
[0033] On the basis of the above embodiment, the number of welding points between the third flange 8 and the vehicle window mounting portion 3 is set to at least two. In the above embodiment, the third welding point 11 has been set as a connection point, and other welding points can also be set to increase the welding strength. For example, the third welding point 11 is close to the side of the transition portion 4, and a fifth welding point can also be set on the third flange 8 away from the side of the transition portion 4 to increase the strength.
[0034] It should be noted that the above two embodiments are not restrictive, and more welding points can be arranged according to actual production needs to improve the connection strength.
[0035] Based on the above embodiment, the second flange 7 of the water trough unit 2 extends into the inner side of the transition portion 4 of the side panel 1. The transition portion 4 of the side panel 1 is a step structure or a structure similar to a step structure. The shape trend of the second flange 7 is the same as the shape of the transition portion 4, so that the second flange 7 and the transition portion 4 can form a tight fit to better implement the welding operation.
[0036] On the basis of the above embodiment, the water trough unit 2 is designed to have trough walls on both sides and a groove 13 in the middle, which is used as a channel for rainwater or car wash water to flow out. The first flange 6, the second flange 7 and the third flange 8 are arranged in sequence along the direction of water flowing out of the groove 13. The first flange 6, the second flange 7 and the third flange 8 are arranged on the trough wall of the water trough unit 2 on the side close to the side panel 1 so as to be welded to the side panel 1.
[0037] Based on the above embodiment, multiple convex tie bars 14 are provided at the bottom of the groove 13. These convex tie bars 14 are formed as protrusions from the sheet metal at the bottom of the groove 13. These convex tie bars 14 are quadrilateral protrusions with curved edges formed by stretching. These convex tie bars 14 are evenly spaced, enhancing the overall strength of the trough unit 2 and preventing deformation. It should be noted that the shape of the convex tie bars 14 not only affects the structural stability, load-bearing capacity, and stress distribution, but also allows for more innovative design options beyond the conventional straight or curved convex tie bars 14. For example, if the bottom of the groove 13 is wide, a widened and slightly flattened convex tie bar 14 design can be used to increase the contact area and improve the stability and strength of the connection. If the bottom of the groove 13 exhibits a unique curve or irregular shape, the convex tie bars 14 can be designed to match the curve to reduce stress concentration and improve the durability of the overall structure. By flexibly adjusting the shape of the convex tie bars 14, it is possible to ensure perfect coordination with the groove 13 structure, thereby improving the performance and service life of the overall structure.
[0038] Furthermore, multiple convex ribs 14 are arranged at intervals at the bottom of the groove 13, and the convex ribs 14 are close to one side of the groove 13. The width of the convex ribs 14 is smaller than the width of the groove 13. There is a gap between the side of the convex ribs 14 and the groove wall of the groove 13 to facilitate the rapid passage of water.
[0039] Based on the above embodiment, the vehicle window mounting portion 3 includes a triangular window mounting area 15, which extends to the tail of the side panel 1, close to the edge of the side panel 1, and the third flange 8 is connected to the edge of the triangular window mounting area 15. In a possible embodiment, the edge of the triangular mounting area is provided with a flange structure matching the third flange 8, and the narrow side portion of the triangular window mounting area 15 is close to the side connected to the third flange 8, so that the triangular window mounting area 15 has a wider sheet metal area, thereby improving the overall connection strength.
[0040] On the basis of the above embodiment, a matching flange structure can be provided on the side of the triangular window installation area 15 close to the connection with the third flange 8. The flange structure of the triangular window installation area 15 can be set in an interval form with different widths. After welding with the third flange 8, a bent contact gap will be formed. In addition, there are gaps between the first flange 6 and the flange portion 5 and between the second flange 7 and the transition portion 4. Sealing protection is formed by the paint protective layer 12. The third flange 8 of the water trough unit 2 is also provided with a fixing hole 16 for fixing the water trough unit 2. The paint protective layer 12 for sealing the gap is bent and bypasses the position of the fixing hole 16 to achieve sealing and fixation, thereby ensuring the sealing and stability of the vehicle body.
[0041] The present invention also provides a vehicle, which includes the vehicle body of the above embodiment. It should be noted that the vehicle can be a variety of types of vehicles, which is not restrictive, such as new energy vehicles, commercial vehicles and other models.
[0042] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
