Description

Technical Field

[0001] The utility model relates to the technical field of vehicle body structures, in particular to a vehicle shotgun structure and a vehicle. Background Art

[0002] With the continuous progress of vehicle design, the NVH performance of vehicles has become a key indicator for measuring vehicle quality. NVH is the English abbreviation of Noise, Vibration, and Harshness, which is a comprehensive parameter for measuring vehicle manufacturing quality. The stiffness of the front cabin frame greatly affects the NVH performance. The shotgun (upper longitudinal beam) structure, especially the Z-direction cavity cross-sectional dimension of the shotgun, has an important impact on the stiffness of the front cabin frame.

[0003] In general, for existing vehicles, the length direction of the vehicle is taken as the X-axis, the width direction of the vehicle is taken as the Y-axis, the height direction of the vehicle is taken as the Z-axis, and the centroid position of the vehicle is taken as the origin to establish a coordinate system for reference of each part of the vehicle.

[0004] However, with the trend of modern vehicle design towards lower and more compact shapes and larger tire sizes, the Z-direction cross-sectional dimension of the shotgun is continuously compressed. The traditional welding method of the inner and outer plates of the shotgun along the Y-direction results in at least 20 mm welding edges on both sides of the inner and outer plates along the Z-direction, thus occupying valuable Z-direction space and compressing the Z-direction cavity dimension of the shotgun, thereby affecting the NVH performance of the vehicle and resulting in poor vehicle quality.

[0024] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present utility model. The following examples are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0025] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" 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 a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0026] In the related art, with the modern vehicle design tending to lower and more compact shapes and larger tire sizes, the Z - direction cross - sectional dimension of the shotgun has been continuously compressed. The traditional welding method of the inner and outer plates of the shotgun along the Y - direction results in at least 20 mm of welding edges on both sides of the inner and outer plates along the Z - direction, thus occupying valuable Z - direction space and compressing the Z - direction cavity dimension of the shotgun, which affects the NVH performance of the vehicle and results in poor vehicle quality.

[0027] In view of this, as Figures 1-3 shown, some embodiments of the present utility model provide a vehicle shotgun structure, including an inner plate 1, an outer plate 2, and a reinforcing plate 3; the reinforcing plate 3 is disposed between the inner plate 1 and the outer plate 2, and the reinforcing plate 3 is respectively connected to the inner plate 1 and the outer plate 2; a receiving cavity 5 is formed between the outer plate 2 and the inner plate 1, and a welding edge 4 is respectively disposed on both sides of the receiving cavity 5, and the reinforcing plate 3 is placed in the receiving cavity 5; at least one welding edge 4 is arranged at an angle with the height direction of the outer plate 2.

[0028] In the above - mentioned embodiment, the inner plate 1, the outer plate 2, and the reinforcing plate 3 can all be made of metal materials, and the inner plate 1, the outer plate 2, and the reinforcing plate 3 can all be formed by stamping metal plates. The inner plate 1, the outer plate 2, and the reinforcing plate 3 can all be arranged to extend along the vehicle body length direction. Among them, taking the vehicle length direction as the x - axis, the vehicle width direction as the Y - axis, and the vehicle height direction as the Z - axis, and establishing a coordinate system with the vehicle's centroid position as the origin. That is, the inner plate 1, the outer plate 2, and the reinforcing plate 3 all extend along the length direction of the X - axis. There is a pair of parallel edges on both sides of the inner plate 1, the outer plate 2, and the reinforcing plate 3. After the reinforcing plate 3 is disposed between the inner plate 1 and the outer plate 2, the inner plate 1, the outer plate 2, and the reinforcing plate 3 are stacked and the edges on both sides are closely fitted. Then, they can be fixed by spot welding or riveting and other fixing methods to make the connection between the inner plate 1, the reinforcing plate, and the outer plate 2 firm, and two welding edges 4 are also formed on both sides. In the cross - section, at least one of the length directions of the two welding edges 4 is arranged at an angle with the height direction of the outer plate 2, that is, at least one of the length directions of the welding edges 4 is arranged at an angle with the Z - axis direction. When the length direction of the welding edge 4 forms an angle with the Z - axis, the space occupied by the welding edge 4 in the Z - axis direction becomes smaller. Therefore, the receiving cavity 5 formed by the outer plate 2 and the inner plate 1 can be provided with a larger Z - direction space, and with the cooperation of the reinforcing plate 3, the shotgun structure is made more firm.

[0029] A vehicle shotgun structure provided by some embodiments of the present utility model includes an inner plate 1, an outer plate 2, and a reinforcing plate 3; the reinforcing plate 3 can increase the overall strength, thus having better NVH performance; a receiving cavity 5 is formed between the outer plate 2 and the inner plate 1, so that the two welding edges 4 do not all extend along the Z direction, thereby effectively reducing the space occupied by the welding edges 4 in the Z direction, enabling the receiving cavity 5 to have a larger size in the Z direction, so that the shotgun has higher strength and better vehicle quality. It solves the technical problem that the Z-direction size of the shotgun in the prior art is small, resulting in poor vehicle quality. It achieves the technical effect that the Z-direction size of the shotgun is large and the vehicle quality is better.

[0030] In an alternative embodiment, the extending directions of the two welding edges 4 are arranged at an angle.

[0031] In the above embodiment, the two welding edges 4 are arranged at an angle. Among them, the first welding edge 4 is arranged on the side away from the tire, and the second welding edge 4 can be arranged on the side close to the tire, and the first welding edge 4 and the second welding edge 4 are arranged at an angle. The length direction of the cross-section of the first welding edge 4 and the length direction of the cross-section of the second welding edge 4 are arranged at an angle, so that at any angle setting, there is a welding edge 4 arranged at an angle with the Z axis, thereby reducing the space occupied by the welding edges 4 in the Z direction.

[0032] In an alternative embodiment, the extending direction of the welding edge 4 close to the tire is set at 45° with the height direction of the outer plate 2, and the extending direction of the welding edge 4 away from the tire is arranged along the height direction of the outer plate 2.

[0033] In the above embodiment, the extending direction of the welding edge 4 close to the tire is arranged to face away from the other welding edge 4. The angle between the welding edge 4 close to the tire and the Z axis can be 45 degrees or 90 degrees, and the extending direction of the welding edge 4 away from the tire can be arranged along the Z axis direction or at an angle with the Z axis, thereby reducing the space occupied by the welding edges 4 in the Z axis direction.

[0034] In an alternative embodiment, both ends of the reinforcing plate 3 are respectively placed between the inner plate 1 and the outer plate 2, and the reinforcing plate 3 is arranged at intervals from the inner wall of the receiving cavity 5.

[0035] In the above embodiment, the reinforcing plate 3 can be arranged at intervals from the inner wall of the receiving cavity 5, or can be partially attached to the inner wall of the receiving cavity 5. In the cross-section, the reinforcing plate 3 can divide the receiving cavity 5 into two triangles, so that the shotgun has higher strength. Further, one point of the reinforcing plate 3 can be connected to the inner plate 1 or the outer plate 2 to fix the reinforcing plate 3, so that the shotgun has higher strength and better NVH performance.

[0036] In an alternative embodiment, the welding edge 4 includes the overlapping edges of the inner plate 1, the reinforcing plate 3, and the outer plate 2.

[0037] In the above embodiment, the welding edge 4 can be disposed at any position where the inner plate 1, the reinforcing plate 3, and the outer plate 2 overlap, or can be disposed at the overlapping edges of the inner plate 1, the reinforcing plate 3, and the outer plate 2. The welding edge 4 can connect the inner plate 1, the reinforcing plate 3, and the outer plate 2 together by spot welding, or can be connected in cooperation with riveting.

[0038] In an alternative embodiment, the welding edge 4 extends along the length direction of the inner plate 1.

[0039] In the above embodiment, since both the inner plate 1 and the outer plate 2 extend along the X-axis direction, the welding edge 4 also extends along the X-axis direction. At the welding edge 4, welding spots or rivet fixing positions are uniformly arranged along the X-axis direction so that the inner plate 1, the reinforcing plate 3, and the outer plate 2 are more firmly connected and the force is more evenly distributed.

[0040] In an alternative embodiment, the outer plate 2 includes a first bending portion 201 and a second bending portion 202.

The first bending portion 201 and the second bending portion 202 can be formed by a stamping machine or a bending machine. The first bending portion 201 and the second bending portion 202 can be perpendicularly arranged and smoothly transitioned. The first bending portion 201 can be parallel to the Y-axis, and the second bending portion 202 can be parallel to the Z-axis. That is, the first bending portion 201 is arranged horizontally, the second bending portion 202 is arranged vertically, the welding edge 4 on one side of the first bending portion 201 is perpendicularly arranged with the first bending portion 201, and the welding edge 4 on one side of the second bending portion 202 is arranged at an angle with the second bending portion 202 and smoothly transitioned, thereby effectively increasing the space of the accommodation cavity 5 and avoiding affecting the space of other parts.

[0042] In an alternative embodiment, the inner plate 1 includes a connecting portion 101, a third bending portion 102, and a fourth bending portion 104. The two ends of the third bending portion 102 are respectively connected to the connecting portion 101 and the fourth bending portion 104. One end of the connecting portion 101 away from the third bending portion 102 is connected to a welding edge 4, and one end of the fourth bending portion 104 away from the third bending portion 102 is connected to another welding edge 4. The connecting portion 101 is arranged parallel to the second bending portion 202, and the fourth bending portion 104 is arranged parallel to the first bending portion 201.

[0043] In the above embodiments, both ends of the connecting portion 101 are smoothly transitioned with the welding edge 4 and the third bending portion 102 respectively. The other end of the third bending portion 102 is smoothly transitioned with another welding edge 4 through the fourth bending portion 104. Among them, the connecting portion 101, the third bending portion 102, the fourth bending portion 104 and the welding edges 4 on both sides can be smoothly transitioned and integrally formed by stamping. The connecting portion 101 can be arranged on the same straight line as the welding edge 4 away from the tire. The connecting portion 101 can be in a plate shape and can be arranged to extend along the Z-axis direction, while the fourth bending portion 104 can be arranged to extend along the Y-axis direction. There is a third bending portion 102 arranged at an angle between the fourth bending portion 104 and the connecting portion 101. The third bending portion 102 can reduce the cross-sectional area of the accommodation cavity 5, making the shotgun occupy less space, but does not affect the maximum width and maximum height of the cross-section of the accommodation cavity 5, so as to save space while ensuring the strength of the shotgun.

[0044] In an alternative embodiment, an avoidance recess is provided on the third bending portion 102 and is recessed in a direction close to the reinforcing plate 3.

[0045] In the above embodiments, the cross-section of the avoidance recess can be in a folded shape, the section of the avoidance recess can be arranged at an obtuse angle, and the avoidance recess can be recessed in a direction close to the reinforcing plate 3, so that the avoidance recess can effectively reduce the occupied space of the third bending portion 102, thereby improving the space utilization rate.
