Description

Technical Field

[0001] This application relates to the field of automotive technology, and in particular to a vehicle body structure and a vehicle. Background Technology

[0002] The front side panel structure of a car is a key component of the body-in-white. Located on both sides of the front of the vehicle, it is an important area that affects the overall structural strength, safety performance, manufacturing process, and appearance of the vehicle.

[0003] Existing front side panel structures typically include a connecting beam, with both ends connecting to the front bumper beam and the A-pillar. The connecting beam is formed by welding two sheet metal parts together, creating a hollow cavity inside. However, to ensure strength, existing front side panel structures are relatively heavy. Furthermore, the structure of the front side panel varies depending on the vehicle model. Utility Model Content

[0004] The main technical problem this application addresses is to provide a vehicle body structure and vehicle that are highly versatile, lightweight, and reduce production costs.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a vehicle body structure, including a front side frame, the front side frame including a first connecting pipe and a second connecting pipe spaced apart along a first direction, the two ends of the first connecting pipe and the two ends of the second connecting pipe being respectively used to connect to a front anti-collision beam and an A-pillar; the front side frame also includes at least one connecting plate extending along the first direction, the connecting plate being connected to the first connecting pipe and the second connecting pipe.

[0006] Wherein, the first connecting pipe and / or the second connecting pipe are round pipes.

[0007] Wherein, the first connecting pipe and / or the second connecting pipe extend along an arc.

[0008] The wall thickness of the first connecting pipe and / or the second connecting pipe is 1mm-2mm. This wall thickness reduces weight while maintaining strength.

[0009] The system comprises multiple connecting plates, spaced apart, which, together with the first connecting pipe and the second connecting pipe, form a frame structure. Two connecting plates, the first connecting pipe, and the second connecting pipe together form a "U"-shaped structure, which provides high stability and further increases the strength of the front frame.

[0010] The connecting plate has a thickness of 1mm-2mm. This thickness reduces weight while maintaining strength.

[0011] The front side frame also includes an arc-shaped plate, with its two ends connected to the front bumper beam and the A-pillar, respectively. The arc-shaped plate is disposed on one side of the first connecting pipe and the second connecting pipe, and the side of the connecting plate away from the first and second connecting pipes is connected to the arc-shaped plate. By incorporating the arc-shaped plate, structural stability is further increased, thereby enhancing the strength of the front side frame in the X direction.

[0012] In this configuration, the first connecting pipe is positioned on the side of the second connecting pipe closest to the roof, and the distance between the second connecting pipe and the arc-shaped plate is greater than the distance between the first connecting pipe and the arc-shaped plate. This structure results in a front side frame that is narrower at the top and wider at the bottom, leading to greater structural stability.

[0013] The second connecting pipe is arc-shaped and protrudes towards the first connecting pipe.

[0014] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide a vehicle including the body structure described in any of the technical solutions.

[0015] The beneficial effects of this application are as follows: Unlike existing technologies, this application replaces the original front side frame with a first connecting pipe, a second connecting pipe, and a connecting plate. The first and second connecting pipes provide connection and strength in the X direction, while the connecting plate connects the first and second connecting pipes in the height direction and provides strength in the Z direction. This structure has a short production cycle, can be rapidly molded, and reduces production costs. When a car is impacted in the X direction, the impact force on the front bumper beam can be transmitted along the first and second connecting pipes towards the A-pillar, dispersing the impact force. Since the first and second connecting pipes are hollow tubular structures, force transmission is ensured while maintaining a lightweight body structure. Furthermore, because the first and second connecting pipes are connected only by one or more connecting plates, the weight of the front side frame is reduced. Additionally, for front side frames with different structures in different car models, universality can be achieved by simply changing the curvature of the first and second connecting pipes, realizing platformization.

[0019] To make the objectives, technical solutions, and effects of this application clearer and more explicit, the following detailed description is provided with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] For ease of understanding, the accompanying diagram shows the mutually orthogonal X-axis, Y-axis, and Z-axis. The direction along the X-axis is called the X-direction, which is the longitudinal direction of the vehicle body; the direction along the Y-axis is called the Y-direction, which is the lateral direction of the vehicle body; and the direction along the Z-axis is called the Z-direction, which is the height direction of the vehicle body. The Z-direction is the normal direction relative to the plane containing the X and Y directions. Furthermore, the view of various elements parallel to the plane containing the X and Y directions is called a top view.

[0021] The vehicle body structure of this application includes a front side frame 10. (See also...) Figure 1 and Figure 2 , Figure 1 This is a perspective view of an embodiment of the front frame of this application. Figure 2 This application is Figure 1 A front view schematic diagram. The front side frame 10 includes a first connecting pipe 11 and a second connecting pipe 12 spaced apart along a first direction. Both ends of the first connecting pipe 11 and both ends of the second connecting pipe 12 are respectively used to connect to the front bumper beam and the A-pillar. The front side frame 10 also includes at least one connecting plate 13 extending along the first direction, and the connecting plate 13 is connected to the first connecting pipe 11 and the second connecting pipe 12.

[0022] Specifically, the first direction is the height direction Z. The first connecting pipe 11 is located at the top, with its two ends connected to the front bumper beam and the A-pillar, respectively. The second connecting pipe 12 is located at the bottom, with its two ends also connected to the front bumper beam and the A-pillar, respectively. The first connecting pipe 11 and the second connecting pipe 12 extend substantially along the X direction. Both the first connecting pipe 11 and the second connecting pipe 12 are steel pipes with a yield strength of 300–600 MPa. The connecting plate 13 is a cold-rolled sheet metal with a yield strength of 300–600 MPa. The plane containing the connecting plate 13 is perpendicular to the X direction, meaning that the connecting plate 13 extends along the planes containing both the Y and Z directions.

[0023] The first connecting pipe 11 and the second connecting pipe 12 can be connected to the connecting plate 13 by welding (e.g., CO2 gas shielded welding) or threaded connection. In one embodiment, see further. Figure 1The connecting plate 13 has through holes corresponding to the first connecting pipe 11 and the second connecting pipe 12. The first connecting pipe 11 and the second connecting pipe 12 pass through the through holes and are welded to the connecting plate 13.

[0024] This application replaces the original front side frame 10 with a first connecting pipe 11, a second connecting pipe 12, and a connecting plate 13. The first connecting pipe 11 and the second connecting pipe 12 provide connection and strength in the X direction, while the connecting plate 13 connects the first connecting pipe 11 and the second connecting pipe 12 in the height direction and provides strength in the Z direction. Since pipe forming is a common process, this structure has a short production cycle, can be quickly formed, and reduces production costs. When the car is impacted in the X direction, the impact force on the front bumper beam can be transmitted along the first connecting pipe 11 and the second connecting pipe 12 towards the A-pillar, dispersing the impact force. Because the first connecting pipe 11 and the second connecting pipe 12 are hollow tubular structures, force transmission can be ensured while maintaining a lightweight body structure, achieving a 30%-50% weight reduction compared to the existing front side frame 10. Furthermore, since the first connecting pipe 11 and the second connecting pipe 12 are connected only by one or more connecting plates 13, the weight of the front side frame 10 can be reduced. In addition, for the front side frame 10 with different structures in different models, the universality of different models can be achieved simply by changing the curvature of the first connecting pipe 11 and the second connecting pipe 12, without changing the shape of the first connecting pipe 11 and the second connecting pipe 12, thus achieving platformization.

[0025] Optionally, in other embodiments, other connecting pipes (not shown) may be provided between the first connecting pipe 11 and the second connecting pipe 12. The connecting pipes extend substantially along the X direction and are connected to the connecting plate to further increase the structural strength.

[0026] Optionally, in one embodiment, both the first connecting pipe 11 and the second connecting pipe 12 are circular pipes. Optionally, the diameters of the first connecting pipe 11 and the second connecting pipe 12 can be the same, so that the first connecting pipe 11 and the second connecting pipe 12 can be made of the same pipe material. In another embodiment, the first connecting pipe 11 and the second connecting pipe 12 can also be tubular structures such as square pipes; in another embodiment, the cross-sectional shapes of the first connecting pipe 11 and the second connecting pipe 12 can also be different.

[0027] Optionally, in one embodiment, both the first connecting pipe 11 and the second connecting pipe 12 extend along an arc to avoid the tire below. In this embodiment, the second connecting pipe 12 protrudes towards the first connecting pipe 11, and the distance between the first connecting pipe 11 and the second connecting pipe 12 first decreases and then increases along the direction from the front of the vehicle to the rear. In other embodiments, the distance between the first connecting pipe 11 and the second connecting pipe 12 may also gradually increase along the direction from the front of the vehicle to the rear, so as to transmit the impact force from the front bumper beam rearward and disperse it to different positions of the A-pillar.

[0028] Specifically, the wall thickness of the first connecting pipe 11 and the second connecting pipe 12 is 1mm-2mm. This wall thickness reduces weight while maintaining strength. The wall thickness of the first connecting pipe 11 and the second connecting pipe 12 can be the same or different; this application does not impose specific limitations.

[0029] In some embodiments, the wall thickness of the first connecting pipe 11 and the second connecting pipe 12 remains consistent throughout. In other embodiments, to ensure the strength of the first connecting pipe 11 and the second connecting pipe 12, they may be thickened in local areas. For example, the overall thickness of the first connecting pipe 11 and the second connecting pipe 12 is 1 mm, but the thickness is increased to 2 mm in local areas.

[0030] Optionally, in some embodiments, protrusions or depressions may be provided on the walls of the first connecting pipe 11 and the second connecting pipe 12 to form a reinforcing structure, thereby increasing the strength of the first connecting pipe 11 and the second connecting pipe 12 and improving the collision performance of the front frame 10.

[0031] Optionally, there may be multiple connecting plates 13, spaced apart, forming a frame structure with the first connecting pipe 11 and the second connecting pipe 12. Specifically, in this embodiment, there are two connecting plates 13, spaced apart along the X-direction. The front connecting plate 13 connects to the front end of the first connecting pipe 11 and the second connecting pipe 12, while the rear connecting plate 13 connects to the middle of the first connecting pipe 11 and the second connecting pipe 12. The two connecting plates 13, the first connecting pipe 11, and the second connecting pipe 12 together form a "U"-shaped structure, which has high stability and further increases the strength of the front frame 10. In other embodiments, there may be more connecting plates 13 to form more frame structures, further increasing structural stability and strength.

[0032] Specifically, the wall thickness of the connecting plate 13 is 1mm-2mm. This wall thickness reduces weight while maintaining strength. The wall thickness of multiple connecting plates 13 can be the same or different; this application does not impose specific limitations.

[0033] In some embodiments, the wall thickness of the connecting plate 13 remains constant. In other embodiments, to ensure the strength of the connecting plate 13 and the first connecting pipe 11 and the second connecting pipe 12, it can be thickened in local areas. For example, the overall thickness of the connecting plate 13 is 1 mm, but the thickness in local areas (e.g., at the connection with the first connecting pipe 11 and the second connecting pipe 12) is increased to 2 mm. Alternatively, reinforcing ribs can be provided on the connecting plate 13 to further increase its strength.

[0034] Optionally, continue reading Figure 1 The front side frame 10 also includes an arc-shaped plate 14. The arc-shaped plate 14 is generally convex, and its two ends are used to connect to the front bumper beam and the A-pillar, respectively. Specifically, the front end of the arc-shaped plate 14 is connected to the front bumper beam connecting plate 15, and the rear end of the arc-shaped plate 14 is connected to the A-pillar connecting plate 16. The arc-shaped plate 14 is disposed inside the first connecting pipe 11 and the second connecting pipe 12 along the Y direction. The side of the connecting plate 13 away from the first connecting pipe 11 and the second connecting pipe 12 is connected to the arc-shaped plate 14. Specifically, the side of the connecting plate 13 facing the arc-shaped plate 14 has a flange, and the connecting plate 13 is fixed to the arc-shaped plate 14 through this flange. By setting the arc-shaped plate 14, the structural stability is further increased, and the strength of the front side frame 10 in the X direction is further increased.

[0035] Optionally, continue reading Figure 1 The first connecting pipe 11 is located on the side of the second connecting pipe 12 near the roof, and the distance between the second connecting pipe 12 and the arc-shaped plate 14 is greater than the distance between the first connecting pipe 11 and the arc-shaped plate 14. Specifically, along the Y direction, the second connecting pipe 12 is located outside the first connecting pipe 11. The connecting plate 13 is basically triangular or trapezoidal in shape to facilitate the connection of the arc-shaped plate 14, the first connecting pipe 11, and the second connecting pipe 12 into one unit. The above structure makes the front side frame 10 narrower at the top and wider at the bottom, resulting in higher structural stability.

[0036] This application also provides a vehicle including the body structure of any of the above embodiments. The vehicle provided in this application can be a pure gasoline vehicle, a hybrid electric vehicle, or a pure electric vehicle, and is also applicable to any other type of vehicle, such as a sports utility vehicle (SUV), off-road vehicle, MPV, etc.

[0037] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
