The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] Reference below Figure 1-Figure 4 A cross member 100 of a vehicle according to an embodiment of the present invention is described.

[0030] Reference Figure 1 As shown, the dashboard cross beam 100 of a vehicle according to an embodiment of the utility model includes: a first cross beam 1 and a second cross beam 2, the extension direction of the first cross beam 1 is the same as the extension direction of the second cross beam 2, the first cross beam 1 is sleeved on the outside of the second cross beam 2, and the first cross beam 1 and the second cross beam 2 are fixedly connected, and the first cross beam 1 is used to install the steering column of the vehicle.

[0031] The vehicle dashboard cross beam 100 includes a first cross beam 1 and a second cross beam 2. The first cross beam 1 and the second cross beam 2 have the same extension direction. The first cross beam 1 and the second cross beam 2 are both along the width direction of the vehicle (i.e. Figure 1 The first crossbeam 1 is configured as a tubular beam, and the second crossbeam 2 is configured as a tubular beam or a solid beam, etc. The first crossbeam 1 is sleeved on the outside of the second crossbeam 2, and the outer peripheral walls of the first crossbeam 1 and the second crossbeam 2 are arranged opposite to each other. A part of the second crossbeam 2 is located in the first crossbeam 1, and a part of the second crossbeam 2 extends into the first crossbeam 1. Along the radial direction of the first crossbeam 1, the radial direction of the first crossbeam 1 is perpendicular to the extension direction of the first crossbeam 1, and the radial direction of the first crossbeam 1 is also perpendicular to the extension direction of the second crossbeam 2. The orthographic projection of the first crossbeam 1 and the orthographic projection of the second crossbeam 2 have an overlapping area. The end of the first crossbeam 1 away from the second crossbeam 2 is fixedly connected to the left side of the vehicle body, that is, the left end of the first crossbeam 1 is fixedly connected to the left side of the vehicle body, and the end of the second crossbeam 2 away from the first crossbeam 1 is fixedly connected to the right side of the vehicle body, that is, the right end of the second crossbeam 2 is fixedly connected to the right side of the vehicle body. Further, the left end of the second crossbeam 2 can be fixedly connected to the left side of the vehicle body.

[0032] The first crossbeam 1 and the second crossbeam 2 are fixedly connected. As some embodiments of the present application, the first crossbeam 1 and the second crossbeam 2 can be directly fixedly connected. The connection method of the first crossbeam 1 and the second crossbeam 2 can be welding connection, bolt connection, etc. As other embodiments of the present application, the first crossbeam 1 and the second crossbeam 2 can be indirectly fixedly connected through other components.

[0033] The vehicle has a steering column, which is used to transfer the driver's torque from the steering wheel to the steering gear, thereby realizing the steering function of the vehicle. The steering column can also absorb energy in the event of a collision to ensure the driver's safety. The steering column is installed at the first cross beam 1.

[0034] In the above embodiment, the dashboard cross beam 100 is configured such that the first cross beam 1 is sleeved on the outside of the second cross beam 2, and the first cross beam 1 and the second cross beam 2 are fixedly connected. When a frontal collision occurs, the dashboard cross beam 100 can be deformed to absorb the collision force. For example, the first cross beam 1 can be deformed to absorb the collision force when a frontal collision occurs, and the second cross beam 2 can also be deformed to absorb the collision force when a frontal collision occurs, so that the dashboard cross beam 100 can play a buffering role in a frontal collision. In addition, when a side collision occurs to the vehicle, the first cross beam 1 can support the left side of the vehicle body, and the second cross beam 2 can support the left side of the vehicle body and the right side of the vehicle body, so that the dashboard cross beam 100 can be reliably supported between the left side of the vehicle body and the right side of the vehicle body, thereby improving the vehicle's anti-side collision capability, increasing the mode of the dashboard cross beam 100 of the vehicle, and being conducive to improving the NVH (noise, vibration and acoustic roughness) performance of the vehicle, thereby improving the user's car experience.

[0035] It should be noted that in the prior art, the main beam and the secondary beam of the instrument panel beam 100 are fixedly connected by shrinking the thick tube or expanding the thin tube. This method has a complicated operation process, a low yield rate, and great welding difficulty. The present application eliminates the process of shrinking the thick tube or expanding the thin tube by configuring the instrument panel beam 100 such that the first beam 1 is sleeved on the outside of the second beam 2, and the first beam 1 and the second beam 2 are fixedly connected, which is beneficial to improving the production efficiency of the product and the qualified rate of the product, thereby improving the flexibility of the welding connection arrangement of other components of the vehicle connected to the first beam 1 and the second beam 2, and also improving the qualified rate of the welding of other components of the vehicle connected to the first beam 1 and the second beam 2.

[0036] According to some embodiments of the present application, Figure 1 and Figure 2As shown, the dashboard cross beam 100 of the vehicle further includes: a connecting member 3 , which is connected between the first cross beam 1 and the second cross beam 2 to fix the first cross beam 1 and the second cross beam 2 .

[0037] Among them, the connecting member 3 can be annular, or the connecting member 3 can also be a block structure. The connecting member 3 is assembled between the first crossbeam 1 and the second crossbeam 2. The connecting member 3 is fixedly connected to the first crossbeam 1 and the second crossbeam 2, so that the relative positions of the first crossbeam 1 and the second crossbeam 2 are fixed, and the first crossbeam 1 and the second crossbeam 2 can also be spaced apart, thereby forming a buffer gap between the first crossbeam 1 and the second crossbeam 2, further improving the buffering effect of the dashboard crossbeam 100.

[0038] As an embodiment of the present application, the connecting member 3 may be a solid circular ring member, which may be located between the first cross beam 1 and the second cross beam 2. The solid circular ring member may be fixedly connected to the first cross beam 1 and the second cross beam 2 by welding, but the present application is not limited thereto. The solid circular ring member may be fixedly connected to the first cross beam 1 and the second cross beam 2 by clamping. By setting the connecting member 3 as a solid circular ring member, the stability of the overall structure of the first cross beam 1, the second cross beam 2 and the connecting member 3 may be enhanced, thereby improving the overall performance of the vehicle.

[0039] As another embodiment of the present application, the connector 3 may be a hollow circular ring, the second cross beam 2 is passed through the connector 3 and fixedly connected to the connector 3, the second cross beam 2 and the connector 3 may be connected by welding, bolting, etc., the first cross beam 1 is sleeved on the outside of the connector 3 and fixedly connected to the connector 3, the first cross beam 1 and the connector 3 may be connected by welding, clamping, etc. By setting the connector 3 as a hollow circular ring, it is helpful to improve the buffering effect of the instrument panel cross beam 100 during the head-on collision of the whole vehicle, and by setting the connector 3 as a hollow circular ring, it is helpful to reduce the weight of the instrument panel cross beam 100, which is beneficial to the lightweight design of the instrument panel cross beam 100.

[0040] According to some embodiments of the present invention, Figure 3 As shown, the first cross beam 1 includes an annular wall 12 , which defines an installation space 13 , a portion of the structure of the second cross beam 2 extends into the installation space 13 , the connecting member 3 is located in the installation space 13 , and the connecting member 3 is located between the annular wall 12 and the second cross beam 2 .

[0041] The first cross beam 1 can be constructed as a tube beam with a circular cross section, and the cross section of the tube beam is a circular cross section, which can improve the bending interface coefficient of the structure of the first cross beam 1. The left end of the second cross beam 2 extends into the installation space 13, and the outer surface of the partial structure of the second cross beam 2 extending into the installation space 13 can be separated from the annular wall 12. The connecting member 3 is located in the installation space 13, and the connecting member 3 is connected between the first cross beam 1 and the second cross beam 2 to fix the first cross beam 1 and the second cross beam 2. The first cross beam 1 includes the annular wall 12, and the annular wall 12 defines the installation space 13, so that the effect of the first cross beam 1 being sleeved on the outside of the second cross beam 2 can be achieved, which facilitates the coordinated assembly of the first cross beam 1 and the second cross beam 2, and is conducive to improving the assembly efficiency of the instrument panel cross beam 100.

[0042] According to some embodiments of the present invention, Figure 1 and Figure 3 As shown, the annular wall 12 is formed with an assembly hole 11 , and the assembly hole 11 is arranged corresponding to the connecting member 3 .

[0043] The annular wall 12 may be configured with an assembly hole 11. After the connector 3 and the second cross beam 2 are assembled in the installation space 13, the connector 3 is arranged opposite to the corresponding assembly hole 11. Furthermore, the number of assembly holes 11 may be multiple, and the number of assembly holes 11 may be, but not limited to, 2, 3, 4, 5, 6, etc. The number of assembly holes 11 may be reasonably set according to actual conditions. Each connector 3 is arranged corresponding to at least one assembly hole 11. When the connector 3 is assembled with the first cross beam 1, the connector 3 and the first cross beam 1 are welded and fixed through the assembly hole 11 to achieve a fixed connection between the connector 3 and the first cross beam 1. By setting the assembly hole 11, the connector 3 and the first cross beam 1 are conveniently fixedly connected, which is more conducive to improving the assembly efficiency of the instrument panel cross beam 100.

[0044] According to some embodiments of the present invention, Figure 2 As shown, the connecting member 3 is annular and is sleeved on the second cross beam 2 .

[0045] Among them, the connecting member 3 can be constructed as an annular structure. Such a configuration can enable the connecting member 3 to be fixedly connected to the first cross beam 1 and the second cross beam 2 in the entire circumferential direction, and can increase the connection area between the connecting member 3 and the first cross beam 1 and the second cross beam 2, so that the first cross beam 1 and the second cross beam 2 can be reliably fixed, thereby improving the structural stability of the dashboard cross beam 100.

[0046] Further, the connecting member 3 may include a connecting plate 32, an inner flange 33 and an outer flange 34, the connecting plate 32 is annular, and has an outer ring and an inner ring, the outer ring is connected to the outer flange 34, the inner ring is connected to the inner flange 33, the inner flange 33 and the outer flange 34 are arranged oppositely and spaced apart, the connecting plate 32, the inner flange 33 and the outer flange 34 jointly define a buffer space 31, the outer flange 34 is used to be fixedly connected to the first beam 1, and the inner flange 33 is used to be fixedly connected to the second beam 2. The cross section of the connecting member 3 may be a U-shaped structure. By configuring the connecting member 3 to include a connecting plate 32, an inner flange 33 and an outer flange 34, the connecting plate 32, the inner flange 33 and the outer flange 34 jointly define a buffer space 31, and the connecting member 3 can play a buffering role during a head-on collision of the entire vehicle, further enhancing the buffering effect of the dashboard cross beam 100. In addition, the connecting plate 32, the inner flange 33 and the outer flange 34 jointly define the buffer space 31, which is beneficial to reducing the weight of the connecting member 3 compared to a solid structure of the connecting member 3, thereby facilitating a lightweight design of the dashboard cross beam 100.

[0047] It should be noted that the connecting member 3 can be designed as a platform according to the different pipe diameter combinations of the first crossbeam 1 and the second crossbeam 2, which is conducive to better controlling the production cost.

[0048] According to some embodiments of the present invention, Figure 2 As shown, there are multiple connecting members 3, and the multiple connecting members 3 are arranged along the extension direction of the second cross beam 2 (i.e. Figure 1 The Y direction as shown) are arranged sequentially.

[0049] As some embodiments of the present application, the number of the connecting members 3 may be multiple, and the number of the connecting members 3 may be but not limited to 2, 3, 4, 5, 6, etc. The number of the connecting members 3 may be reasonably set according to actual conditions. Figure 1 The connecting members 3 and the second cross beam 2 are separate parts, and the multiple connecting members 3 are arranged in sequence along the extension direction of the second cross beam 2 (i.e. Figure 1 The Y direction shown in the figure) is sequentially sleeved on the second beam 2, and the multiple connecting parts 3 and the second beam 2 can be connected by welding. The multiple connecting parts 3 and the second beam 2 connected into one by welding are then assembled as a whole on the first beam 1. The positions of the multiple connecting parts 3 sleeved on the second beam 2 can be set according to the distribution positions of the assembly holes 11 on the first beam 1, so that each connecting part 3 can have a corresponding assembly hole 11, so as to ensure that the connecting part 3 and the first beam 1 can be welded at the assembly hole 11.

[0050] Furthermore, each connecting member 3 is provided with at least one assembly hole 11. The present application takes the example of each connecting member 3 being provided with multiple assembly holes 11. The multiple assembly holes 11 corresponding to the same connecting member 3 are arranged in sequence along the circumference of the first beam 1. By providing each connecting member 3 with multiple assembly holes 11, the connection area between the connecting member 3 and the first beam 1 can be increased, which is beneficial to improving the connection strength between the connecting member 3 and the first beam 1.

[0051] As other embodiments of the present application, the connecting member 3 is sleeved on the second beam 2 and is formed integrally with the second beam 2, that is, the connecting member 3 and the second beam 2 are constructed as an integrally formed part, and the integrally formed part has good structural strength. By forming the connecting member 3 and the second beam 2 integrally, the connection reliability between the connecting member 3 and the second beam 2 can be improved, and the probability of breakage at the connection between the connecting member 3 and the second beam 2 can be reduced, which is beneficial to improving assembly efficiency and reducing assembly difficulty.

[0052] According to some embodiments of the present invention, Figure 1 As shown, the first cross beam 1 and the second cross beam 2 are spaced apart.

[0053] The second cross beam 2 extends into the installation space 13 of the first cross beam 1, and the second cross beam 2 is spaced apart from the first cross beam 1 to form a buffer gap between the first cross beam 1 and the second cross beam 2. The connector 3 is located in the buffer gap, and the connector 3 is located between the first cross beam 1 and the second cross beam 2. The connector 3 can be respectively welded to the first cross beam 1 and the second cross beam 2. The second cross beam 2 is spaced apart from the first cross beam 1 to form the buffer gap, which is conducive to the welding connection of the first cross beam 1 and the second cross beam 2 with the connector 3. At the same time, the buffer gap can play a better buffering role when the instrument panel cross beam 100 is subjected to a forward collision.

[0054] According to some embodiments of the present invention, Figure 1 As shown, the centerline axis of the first crossbeam 1 and the centerline axis of the second crossbeam 2 coincide with each other.

[0055] Among them, the centerline axis of the first crossbeam 1 coincides with the centerline axis of the second crossbeam 2. This arrangement is conducive to the welding connection between the first crossbeam 1 and the second crossbeam 2 and the connecting piece 3, and has good coaxiality. By arranging the centerline axis of the first crossbeam 1 and the second crossbeam 2 to coincide, it is beneficial to improve the overall structural strength of the instrument panel crossbeam 100, and, along the circumference of the instrument panel crossbeam 100, it is beneficial to improve the structural consistency of the instrument panel crossbeam 100.

[0056] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the second transverse beam 2 is designed as a tubular beam.

[0057] The second cross beam 2 can be constructed as a tube beam, and the cross section of the tube beam is a ring cross section, which can improve the bending interface coefficient of the structure of the first cross beam 1. By constructing the second cross beam 2 as a tube beam, the weight of the second cross beam 2 can be reduced on the basis of meeting the structural strength of the second cross beam 2, thereby achieving the purpose of lightweight design, which is conducive to realizing the lightweight design of the instrument panel cross beam 100 and reducing the weight of the entire vehicle.

[0058] The vehicle according to some embodiments of the present invention comprises the instrument panel cross beam 100 of the vehicle of the above embodiment. By setting the dashboard cross beam 100 such that the first cross beam 1 is sleeved on the outside of the second cross beam 2, and the first cross beam 1 and the second cross beam 2 are fixedly connected, the dashboard cross beam 100 can deform and absorb the collision force when a frontal collision occurs. For example, the first cross beam 1 can deform and absorb the collision force when a frontal collision occurs, and the second cross beam 2 can also deform and absorb the collision force when a frontal collision occurs, so that the dashboard cross beam 100 can play a buffering role in a frontal collision. In addition, when the vehicle has a side collision, the first cross beam 1 can support the left body side, and the second cross beam 2 can support the left body side and the right body side, so that the dashboard cross beam 100 can be reliably supported between the left body side and the right body side, thereby improving the vehicle's anti-side collision ability, so as to increase the mode of the vehicle's dashboard cross beam 100, which is beneficial to improving the NVH (noise, vibration and acoustic roughness-Noise, Vibration, Harshness) performance of the vehicle, thereby improving the user's car experience.
