Technical Field

[0002] The car dashboard crossbeam serves as the skeleton of the interior instrument panel of the car body. Its main function is to support the dashboard system. At the same time, because it is connected to the A-pillar, front surround and central channel of the car body, it actually also has a gain effect on the overall rigidity of the car body.

[0003] As society's requirements for automobile safety and lightweight become higher and higher, the strength and lightweight structure of the dashboard crossbeam assembly are increasingly valued. However, the overall structure of the dashboard crossbeam assembly in the prior art is relatively complex, and thick materials are often used to achieve structural reinforcement. For the lightweight demand, high-cost magnesium-aluminum alloys and composite materials are used. For example, Chinese utility model patent CN209426867U discloses a dashboard crossbeam assembly and its vehicle. The crossbeam, end plate, central bracket and front enclosure connecting bracket that constitute the dashboard crossbeam assembly are die-casted with aluminum alloy profiles to achieve the strength and lightweight requirements of the dashboard crossbeam assembly. Although the lightweight demand is solved to a certain extent, there are still problems of relatively redundant structure and high cost.

[0060] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0061] Example 1

[0062] The purpose of the utility model is to solve the problems of structural redundancy of the automobile instrument panel cross beam assembly and high cost of achieving lightweight in the prior art. The embodiment of the utility model discloses an automobile instrument panel cross beam assembly 100, referring to Figure 1 as well as Figure 2 , including a crossbeam 110 and a plurality of connecting brackets arranged on the crossbeam 110, wherein the plurality of connecting brackets are arranged on the crossbeam 110 at intervals along the length direction of the crossbeam 110; wherein the plurality of connecting brackets include a plurality of strengthening connecting brackets and a plurality of lightweight connecting brackets, wherein the plurality of strengthening connecting brackets are fixedly connected to the strengthening connecting area A of the crossbeam 110 at intervals (such as Figure 3 The area shown by the dashed box A).

[0063] Specifically, refer to Figure 1 as well as Figure 2 The automobile instrument panel cross beam assembly 100 includes a cross beam 110 and a plurality of connection brackets arranged on the cross beam 110. The plurality of connection brackets include a plurality of reinforced connection brackets and a plurality of lightweight connection brackets, and the plurality of reinforced connection brackets are fixedly connected to the reinforced connection area A of the cross beam 110 at intervals. By providing a plurality of reinforced connection brackets and the reinforced connection area A, the reinforced connection brackets are used to connect the areas that need to be strengthened and protected, and the connection strength of the reinforced connection area A is fully guaranteed; by providing a plurality of lightweight connection brackets, the lightweight connection brackets are used to connect the conventional connection parts, and on the basis of ensuring the connection strength of the lightweight connection brackets, the bracket structure redundancy is reduced for the conventional connection parts, while the weight of the connection brackets is reduced to the greatest extent.

[0064] It should be noted that in this embodiment, the reinforced connection area A is preferably set on the main driving side, thereby ensuring the strength of the main driving side. That is to say, the present application is to set a reinforced connection bracket and a lightweight connection bracket, and adopt a reinforced connection bracket to connect the areas with high connection strength requirements and the areas that need to be strengthened and protected, so as to fully ensure the strength of the connection; and adopt a lightweight connection bracket to connect the areas with low connection strength requirements and conventional connection parts. The lightweight connection bracket reduces the redundancy of the bracket structure while minimizing the weight of the connection bracket on the basis of ensuring the connection strength. It should be noted that the present application does not require the materials of the reinforced connection bracket and the lightweight connection bracket. Therefore, under the premise that the lightweight connection bracket is set to reduce the weight of the connection bracket, the reinforced connection bracket and the lightweight connection bracket can be made of relatively cheap steel and other materials, further saving the cost of lightweighting from the material selection. Those skilled in the art should understand that in another embodiment, the reinforced connection area can be set in the middle according to the needs, and the lightweight connection bracket can be set on both sides of the reinforced connection area, or the reinforced connection area can be set on the co-driver side, and the lightweight connection bracket can be set on the main driving side, or the reinforced connection bracket and the lightweight connection bracket can be set at intervals.

[0065] Next, the specific reinforced connecting bracket and lightweight connecting bracket in the automobile instrument panel cross beam assembly disclosed in this embodiment are described:

[0066] refer to Figure 3 The reinforced connecting bracket includes a driver's side A-pillar connecting bracket 120, a front panel reinforced connecting bracket 130, and a driver's side central channel connecting bracket 140; the lightweight connecting bracket includes a passenger side central channel connecting bracket 150, a front panel lightweight connecting bracket 160, and a passenger side A-pillar connecting bracket 170; and along the length direction of the cross beam 110, the driver's side A-pillar connecting bracket 120, the front panel reinforced connecting bracket 130, the driver's side central channel connecting bracket 140, the passenger side central channel connecting bracket 150, the front panel lightweight connecting bracket 160, and the passenger side A-pillar connecting bracket 170 are sequentially arranged on the cross beam 110.

[0067] With the above structural settings, refer to Figure 3 The reinforced connecting bracket includes a main driver's side A-pillar connecting bracket 120, a front panel reinforced connecting bracket 130, and a main driver's side central channel connecting bracket 140, and the main driver's side A-pillar connecting bracket 120, the front panel reinforced connecting bracket 130, and the main driver's side central channel connecting bracket 140 are sequentially arranged in the reinforced connecting area A; by arranging the reinforced connecting bracket and the reinforced connecting area A on the main driver's side, the connection strength on the driver's side is protected to the greatest extent; the lightweight connecting bracket includes a passenger side central channel connecting bracket 150, a front panel lightweight connecting bracket 160, and a passenger side A-pillar connecting bracket 170, and the lightweight connecting bracket is mainly arranged on the passenger side. On the basis of ensuring the connection strength of the lightweight connecting bracket, the lightweight connecting bracket reduces the bracket structure redundancy while reducing the weight of the connecting bracket to the greatest extent, thereby reducing the lightweight cost.

[0068] More specifically, along the length direction of the cross beam 110 from the driver's side to the passenger's side, the driver's side A-pillar connecting bracket 120, the front wall reinforcement connecting bracket 130, the driver's side central channel connecting bracket 140, the passenger's side central channel connecting bracket 150, the front wall lightweight connecting bracket 160, and the passenger's side A-pillar connecting bracket 170 are sequentially arranged on the cross beam 110. The above distribution method is to arrange the reinforcement connecting bracket and the lightweight connecting bracket in different areas. Under the premise of meeting the connection strength, for areas such as the driver's side that require higher connection strength, the driver's side A-pillar connecting bracket 120 and the front wall reinforcement connecting bracket are used. Reinforced connecting brackets such as the connecting bracket 130 and the driver's side central channel connecting bracket 140 further improve the connection strength; for conventional connecting parts, lightweight connecting brackets such as the passenger side central channel connecting bracket 150, the front panel lightweight connecting bracket 160, and the passenger side A-pillar connecting bracket 170 are used to reduce the redundancy of the bracket structure and reduce the weight of the connecting bracket. The mixed use of reinforced connecting brackets and lightweight connecting brackets reduces the structural redundancy of the automobile dashboard crossbeam assembly 100 while reducing the weight of the connecting bracket while ensuring the required connection strength, thereby reducing the lightweight cost.

[0069] Further, in the automotive instrument panel cross beam assembly according to the utility model, reference is made to Figure 3 The front enclosure reinforcement connecting bracket 130 and the front enclosure lightweight connecting bracket 160 are extended from the cross beam 110 toward the front enclosure side of the vehicle along a first direction; the driver's side A-pillar connecting bracket 120 and the passenger's side A-pillar connecting bracket 170 are extended along a vertical direction; the driver's side central channel connecting bracket 140 and the passenger's side central channel connecting bracket 150 are extended from the cross beam 110 toward the vehicle's central channel along a second direction; wherein the first direction and the second direction are both orthogonal to the length direction of the cross beam 110.

[0070] With the above-mentioned structural setting, the front enclosure reinforcement connecting bracket 130 and the front enclosure lightweight connecting bracket 160 are extended from the cross beam 110 toward the front enclosure side of the vehicle and along the first direction, and the first direction is orthogonal to the length direction of the cross beam 110. Specifically, when the front enclosure reinforcement connecting bracket 130 is connected to the front enclosure, the connection strength between the automobile instrument panel cross beam assembly 100 and the main driver's side front enclosure is guaranteed; when the front enclosure lightweight connecting bracket 160 is connected to the front enclosure, on the basis of ensuring the connection strength between the automobile instrument panel cross beam assembly 100 and the front enclosure, the weight of the bracket connected to the front enclosure is reduced, thereby reducing the lightweight cost; the first direction is orthogonal to the length direction of the cross beam 110, which ensures that the front enclosure reinforcement connecting bracket 130 and the front enclosure lightweight connecting bracket 160 have better force conduction performance relative to the front enclosure and the cross beam 110. The driver's side A-pillar connecting bracket 120 and the passenger's side A-pillar connecting bracket 170 are extended in the vertical direction. Specifically, when the driver's side A-pillar connecting bracket 120 is connected to the driver's side A-pillar, the connection strength between the automobile instrument panel cross beam assembly 100 and the driver's side A-pillar is guaranteed; when the passenger's side A-pillar connecting bracket 170 is connected to the passenger's side A-pillar, while ensuring the connection strength between the automobile instrument panel cross beam assembly 100 and the passenger's side A-pillar, the weight of the bracket connected to the passenger's side A-pillar is reduced, thereby reducing the lightweight cost. The driver's side central channel connecting bracket 140 and the passenger's side central channel connecting bracket 150 are extended from the cross beam 110 toward the vehicle's central channel along a second direction, and the second direction is orthogonal to the length direction of the cross beam 110. Specifically, when the driver's side central channel connecting bracket 140 is connected to the central channel, the connection strength between the automobile instrument panel cross beam assembly 100 and the driver's side central channel is ensured; when the passenger's side central channel connecting bracket 150 is connected to the central channel, the connection strength between the automobile instrument panel cross beam assembly 100 and the passenger's side central channel is ensured, while reducing the weight of the bracket connected to the passenger's side central channel. The second direction is orthogonal to the length direction of the cross beam 110, which ensures that the driver's side central channel connecting bracket 140 and the passenger's side central channel connecting bracket 150 have better force conduction performance relative to the central channel and the cross beam 110.

[0071] Further, the reinforced connecting bracket in the automobile instrument panel cross beam assembly disclosed in this embodiment is described as follows:

[0072] The reinforced connecting bracket includes at least a reinforced connecting bracket body; wherein the reinforced connecting bracket body includes a first reinforced connecting plate and a second reinforced connecting plate arranged opposite to each other, and a closed cavity is formed between the first reinforced connecting plate and the second reinforced connecting plate; in the extension direction of the reinforced connecting bracket body, at least one side end of the first reinforced connecting plate extends out of the second reinforced connecting plate; and the inner circumferential surfaces of the first reinforced connecting plate and the second reinforced connecting plate are both provided with reinforcing ribs.

[0073] With the above-mentioned structural setting, the reinforced connection bracket body includes a first reinforced connection plate and a second reinforced connection plate arranged opposite to each other, and a closed cavity is formed between the first reinforced connection plate and the second reinforced connection plate. The structure of the closed cavity improves the ability of the reinforced connection bracket to bear force and conduct force, thereby enhancing the connection strength of the reinforced connection bracket body. Specifically, the closed cavity can be a cavity of regular shape such as a cylindrical cavity and a rectangular cavity. By arranging reinforcing ribs on the inner circumferential surfaces of the first reinforced connection plate and the second reinforced connection plate, the connection strength of the reinforced connection bracket body is further enhanced. Preferably, the reinforcing ribs extend along an extension direction perpendicular to the extension direction of the reinforced connection bracket body. This arrangement makes the reinforced connection bracket body have stronger tensile and compressive resistance.
