[0036] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0037] In related technologies, the dashboard crossbeam is a structural component that provides installation and support for the dashboard assembly and other system parts (such as the steering column, air conditioning, entertainment system, instrument cluster, front passenger side airbag, etc.); it is directly connected to the vehicle body, bearing, absorbing and transmitting the energy and load in the collision of the entire vehicle, and is an important part of the vehicle's safety performance.

[0038] However, the increase in related intelligent devices on the steering column has led to an increase in the weight of the steering column. Specifically, the wire-controlled steering column, as a new type of intelligent steering column, has higher safety, driving comfort and intelligence. However, the linear steering column is heavier due to the motor installed on it. As a result, the supporting strength of the dashboard beam for the weighted steering column cannot meet the use requirements, causing the steering system to vibrate during vehicle driving, reducing the driver's experience comfort.

[0039] Therefore, the present application provides an instrument panel crossbeam, an instrument panel assembly, a steering column assembly and a vehicle, which can solve or improve the problem of vibration of the steering system during vehicle driving and poor driver experience.

[0040] The following combination Figures 1 to 9 , describing the embodiments of the present application.

[0041] According to an embodiment of the present application, in a first aspect, a dashboard cross beam is provided, such as Figures 1 to 6 As shown, it includes a crossbeam body 1, a front bracket 2 and a rear bracket 3; Figure 2 and Figure 4 As shown, the front bracket 2 is connected to the beam body 1 on one side along the first direction by welding or bolting, and a front mounting portion 201 is provided on the front bracket 2, which is suitable for connecting to the steering column assembly 5, wherein the first direction is set at an angle to the axial direction of the beam body 1; the rear bracket 3 is connected to the beam body 1 on the other side along the first direction by welding or bolting, and a rear mounting portion 301 is provided on the rear bracket 3, which is suitable for connecting to the steering column assembly 5.

[0042] It needs to be explained that, Figure 2 As shown, the first direction is set at an angle with the axial direction of the beam body 1, that is, the first direction is not parallel to the axial direction of the beam body 1, and is set crosswise; of course, preferably, the angle between the first direction and the axial direction of the beam body 1 is 60°~120°; more preferably, the angle between the first direction and the axial direction of the beam body 1 is 90°.

[0043] Specifically, the crossbeam body 1 is a tube, and its cross section is annular, and can be a circular ring, a square ring, or the like. The specific shape can be selected and set according to the situation. The crossbeam body 1 can also be a cast aluminum part.

[0044] The front bracket 2 and the rear bracket 3 can be brackets formed by bending and welding steel plates, or can be castings, and are connected to the crossbeam body 1 by welding or bolting.

[0045] The front mounting portion 201 and the rear mounting portion 301 are both bolt through holes, or through holes with nuts welded thereto, and are connected to the steering column assembly 5 via fasteners, which are specifically bolts and nuts or bolts.

[0046] In this embodiment, a front bracket 2 and a rear bracket 3 are respectively connected to the two sides of the beam body 1 along the first direction to connect with the steering column assembly 5, so as to avoid the connection between the steering column assembly 5 and the instrument panel beam forming a single cantilever structure (that is, the steering column assembly 5 is only connected to the bracket located on one side of the beam body 1), thereby enhancing the integrity of the steering column assembly 5 and the instrument panel beam, thereby enhancing the inherent strength of the instrument panel beam, improving the support stability of the steering column assembly 5, preventing the steering system from vibrating or shaking during vehicle driving, and improving the driver's experience comfort.

[0047] In one embodiment, Figure 2 and Figure 4 As shown, the front bracket 2 includes a front connecting plate 202 and a first reinforcing plate 203. The front connecting plate 202 is connected to the beam body 1 by welding or bolting. A first step portion 2021 is provided on the front connecting plate 202. The part of the first step portion 2021 close to the beam body 1 is connected to the beam body 1 by welding or bolting. A second step portion 2022 is provided on the first step portion 2021. The part of the second step portion 2022 close to the beam body 1 is connected to the beam body 1 by welding or bolting. The front mounting portion 201 is provided on the front connecting plate 202; at least one of the two sides of the second step portion 2022 is provided with a first reinforcing plate 203. The first reinforcing plate 203 is connected to the second step portion 2022 and the first step portion 2021 by welding or bolting. The connecting part of the first step portion 2021 and the second step portion 2022 is spaced apart from the first reinforcing plate 203.

[0048] It needs to be explained that a first reinforcing plate 203 is provided on at least one of the two sides of the second step portion 2022. The specific solution is: a first reinforcing plate 203 is provided on one side of the second step portion 2022, or a first reinforcing plate 203 is provided on the other side of the second step portion 2022, or a first reinforcing plate 203 is provided on both sides of the second step portion 2022.

[0049] It should be noted that the shapes of the first step portion 2021 and the second step portion 2022 can be rectangular, trapezoidal or other step shapes, as long as they can enhance the anti-deformation properties. Preferably, they are rectangular step shapes.

[0050] Specifically, the front connecting plate 202 and the first reinforcing plate 203 are both made of sheet metal through punching, bending and welding, and are connected to each other by welding and / or bolting; of course, the front connecting plate 202 and the first reinforcing plate 203 can also be formed by integral casting and then undergo secondary machining.

[0051] It should be noted that the connection between the first step portion 2021 and the second step portion 2022 is spaced apart from the first reinforcing plate 203, that is, the first reinforcing plate 203 and the first step portion 2021 and the second step portion 2022 form a triangular reinforcing structure. As for the specific connection between the first reinforcing plate 203 and the first step portion 2021 and the second step portion 2022, it can be selected and set according to actual conditions.

[0052] In this embodiment, Figure 2 and Figure 4 As shown, the first reinforcing plate 203 and the first step portion 2021 and the second step portion 2022 form a triangular reinforcing structure to enhance the strength between the first protrusion and the second protrusion, thereby enhancing the deformation resistance of the front mounting portion 201, further improving the supporting stability of the dashboard cross beam on the steering column assembly 5, and further improving the driver's experience comfort.

[0053] In one embodiment, Figure 2 As shown, the front bracket 2 also includes a front connecting box 204. Specifically, the front connecting box 204 is made of sheet metal through punching, bending and welding. The front connecting box 204 is connected to the end of the second step portion 2022 away from the crossbeam body 1 by welding. The front connecting box 204 is suitable for connection with the front panel sheet metal. Specifically, the connection structure between the front connecting box 204 and the front panel sheet metal is an existing structure and will not be described in detail here.

[0054] In this embodiment, by connecting the front connection box 204 to the front panel, the strength of the front bracket 2 can be further enhanced, and the support stability of the steering column assembly 5 can be improved.

[0055] In one embodiment, the axial length of the second step portion 2022 along the beam body 1 is 75 mm to 85 mm. Preferably, the axial length of the box body along the beam body 1 is any one of 75 mm, 76 mm, 77 mm, 78 mm, 79 mm, 80 mm, 81 mm, 82 mm, 83 mm, 84 mm and 85 mm, and more preferably 76 mm.

[0056] In this embodiment, the axial length of the second step portion 2022 along the crossbeam body 1 is 75 mm to 85 mm. Within this range, the strength of the second step portion 2022 can meet the support requirements for the steering column assembly 5 and avoid shaking and vibration; if the length of the second step portion 2022 is less than the above range, the strength of the front bracket 2 cannot guarantee the vibration of the steering column assembly 5; if the length of the second step portion 2022 is greater than the above range, the second step portion 2022 itself has excessive strength and is too large in size, which will affect the layout of other components.

[0057] In one embodiment, Figure 2 As shown, the front connecting plate 202 is provided with two front mounting portions 201 spaced apart along the first direction at both sides of the first step portion 2021; and / or, as shown Figure 4 As shown, two rear mounting portions 301 are provided on the rear bracket 3 along the axial direction of the crossbeam body 1. Specifically, both the front mounting portion 201 and the rear mounting portion 301 are through-holes for bolts or through-holes for welding nuts; of course, other structures are also possible as long as they can connect and secure the steering column assembly 5.

[0058] In this embodiment, four front mounting portions 201 arranged in an array are provided on the front bracket 2, and two rear mounting portions 301 are provided on the rear bracket 3 to connect with the steering column assembly 5. Since the weight of the steering column assembly 5 is mainly concentrated on the front mounting bracket, the number of the front mounting portions 201 is greater than the number of the rear mounting portions 301, so that the connection force between the steering column assembly 5 and the instrument panel cross beam can be reasonably distributed, thereby improving the integrity of the steering column assembly 5 and the instrument panel cross beam, and enhancing the stability of the instrument panel cross beam in supporting the steering column assembly 5.

[0059] In one embodiment, Figure 1 and Figure 2 As shown, the dashboard cross beam also includes a connecting beam 4, and a connecting beam 4 is provided on at least one of the two sides of the front bracket 2. One end of the connecting beam 4 is connected to the cross beam body 1 by welding or screwing, and the other end of the connecting beam 4 is suitable for being connected to the front panel metal by screwing.

[0060] Specifically, the first connecting beam 4 and the second connecting beam 4 are both sheet metal parts supported by at least one process such as punching, bending, welding, etc.; they can also be parts such as castings that can play a supporting and connecting role.

[0061] In this embodiment, by providing the connecting beam 4, the connection strength between the instrument panel cross beam and the front panel metal at the front bracket 2 can be enhanced, thereby increasing the deformation resistance of the instrument panel cross beam at the front bracket 2, thereby improving the supporting stability of the instrument panel cross beam on the steering column assembly 5.

[0062] In one embodiment, Figure 4 As shown, a avoidance portion 101 is provided on the crossbeam body 1 near the steering column. The avoidance portion 101 is concave. Specifically, the concave shape can be a concave shape of any shape, such as a circular concave shape or a rectangular concave shape, as long as it can avoid the steering column assembly 5. The storage function of the steering column assembly 5 is retained. When the steering wheel is in a leisure or collision state, it can be retracted to increase the space in the cockpit and reduce the pressure damage to the driver; and / or, as Figure 2 and Figure 4 As shown, the first step portion 2021 is opened at both ends along the first direction; and / or, as shown Figure 2 and Figure 4 As shown, the second step portion 2022 is open at both ends along the first direction, which can reduce weight and cost without reducing the strength of the front connecting plate 202; and / or, as shown Figure 2 As shown, the front bracket 2 further includes a second reinforcing plate 205, and the second reinforcing plate 205 is provided on at least one of the parts of the front connecting plate 202 located on both sides of the first step portion 2021. The provision of the second reinforcing plate 205 can enhance the anti-deformation ability of the front connecting plate 202; and / or, as Figures 5 to 8 As shown, the rear bracket 3 includes a connected rear connecting plate 302 and a rear reinforcing plate 303, and the rear mounting portion 301 is arranged on the rear connecting plate 302, which can enhance the deformation resistance of the rear bracket 3 to enhance the stability of the steering column assembly 5; and / or, the front connecting plate 202 is provided with reinforcing ribs 2023 at the portion where it is connected to the crossbeam body 1 along the axial side edges of the crossbeam body 1, and the shape of the reinforcing ribs 2023 is triangular or L-shaped.

[0063] According to an embodiment of the present application, in a second aspect, a dashboard assembly is provided, comprising the dashboard cross beam in any one embodiment of the first aspect.

[0064] In this embodiment, since the instrument panel assembly includes an instrument panel cross beam, which has the same technical effect as the instrument panel cross beam, it will not be described in detail here.

[0065] According to an embodiment of the present application, in a third aspect, a steering column assembly 5 is provided, which is suitable for being installed on the instrument panel cross beam in any one embodiment of the first aspect, such as Figure 9 As shown, it includes a steering column body 501 and a mounting bracket 502; the mounting bracket 502 is connected to the steering column body 501, and a front fixing portion 5021 and a rear fixing portion 5022 are provided on the mounting bracket 502, which are respectively suitable for connecting with the front mounting portion 201 and the rear mounting portion 301.

[0066] In this embodiment, since the steering column assembly 5 is adapted and installed with the instrument panel cross beam, it has the same technical effect as the instrument panel cross beam and will not be described in detail here.

[0067] According to an embodiment of the present application, in a fourth aspect, a vehicle is provided, comprising the steering column assembly 5 in the third aspect and / or the instrument panel assembly in the second aspect.

[0068] Specifically, the vehicle can be a new energy vehicle or a fuel vehicle; more specifically, the vehicle can be a sedan, SUV, truck, etc., which has a steering column assembly 5 and / or a dashboard cross beam.

[0069] In this embodiment, because the vehicle includes a steering column assembly 5 and / or an instrument panel assembly, which has the same technical effect as the instrument panel cross beam, they are not described in detail here.
