Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] While existing instrument panel reinforcement beam assemblies improve strength and rigidity, they also increase the weight of the instrument panel reinforcement beam assembly. This is not conducive to the lightweight design of the vehicle and can also affect the modal performance of the instrument panel. For example, it may cause the instrument panel to be prone to vibration and noise, affecting the driving experience and the overall performance of the vehicle.

[0020] The instrument panel reinforcing beam assembly 100 of this invention features a reinforcing bracket 30 within the mounting bracket 20. The reinforcing bracket 30 and the mounting bracket 20 together define a cavity structure. This cavity structure achieves hollow lightweighting by removing internal non-load-bearing materials, reducing weight while maintaining strength. It enhances the structural strength of the mounting bracket 20 while meeting lightweight design requirements, reducing the risk of deformation. Furthermore, the cavity structure significantly improves the bending resistance of the mounting bracket 20 by altering its cross-sectional moment of inertia. The cavity structure also absorbs and reflects sound waves, reducing vibration and noise propagation, thereby reducing vibration and noise during vehicle operation. This effectively improves the modal performance of the instrument panel and contributes to enhancing overall vehicle performance and fuel economy.

[0021] The following is for reference. Figures 1-4The present invention describes an instrument panel reinforcement beam assembly 100 and a vehicle according to an embodiment of the present invention. The instrument panel reinforcement beam assembly 100 includes: The crossbeam body 10 extends along a first direction; Multiple mounting brackets 20 are fixed to the crossbeam body 10, and the multiple mounting brackets 20 are arranged at intervals along the first direction. The mounting brackets 20 are used to fix the vehicle body. The reinforcing bracket 30 is fixedly mounted on at least one mounting bracket 20, and the mounting bracket 20 and the corresponding reinforcing bracket 30 together define the cavity structure.

[0022] Among them, such as Figure 1 As shown, the first direction is the Y-direction, which is the width direction of the vehicle; the X-direction is the length direction of the vehicle; and the Z-direction is the height direction of the vehicle. The crossbeam body 10 extends along the first direction. Multiple mounting brackets 20 can be provided, such as two, three, or four, but this invention is not limited to this; other numbers of mounting brackets 20 can also be used, and the arrangement can be reasonably determined according to actual conditions, as long as there are multiple mounting brackets 20. In a specific embodiment of this invention, there can be two mounting brackets 20, both of which are fixed to the crossbeam body 10. In some embodiments of this invention, the mounting brackets 20 and the crossbeam body 10 can be fixedly connected by welding or by bolts, but this invention is not limited to these methods. The mounting brackets 20 and the crossbeam body 10 can also be fixedly connected in other ways, as long as both mounting brackets 20 are fixed to the crossbeam body 10.

[0023] Furthermore, two mounting brackets 20 are arranged sequentially at intervals along the first direction. Each mounting bracket 20 is fixedly connected to both ends of the crossbeam body 10 and is used to fix it to the vehicle body to assemble the instrument panel reinforcement beam assembly 100 onto the vehicle body. The crossbeam body 10, as the core load-bearing component of the instrument panel reinforcement beam assembly 100, is connected to the vehicle body via the mounting brackets 20 at both ends. This allows the load generated by the instrument panel and its accessories (such as air conditioning, wiring harnesses, and airbags) to be evenly distributed to the A-pillars or front bulkhead areas on both sides of the vehicle body, avoiding localized stress concentration caused by single-point or unilateral force application, and significantly improving the overall structural bending and torsional stiffness. For example, in a frontal collision, the crossbeam body 10 transmits the impact force to the vehicle's longitudinal beams through the mounting brackets 20 at both ends, reducing deformation in the instrument panel area and protecting driver safety.

[0024] A reinforcing bracket 30 is fixed to at least one mounting bracket 20. There may be one mounting bracket 20 with a reinforcing bracket 30, or two, three, or an equal number of mounting brackets 20 with reinforcing brackets 30. In a specific embodiment of this invention, each mounting bracket 20 is fixed with a reinforcing bracket 30. The mounting bracket 20 and the corresponding reinforcing bracket 30 together define the cavity structure, which can significantly improve the bending stiffness of the mounting bracket 20. It can also disperse concentrated loads to a larger area through the cavity wall, reducing local stress peaks. The arrangement of the reinforcing bracket 30 can guide stress flow, avoiding cracking or deformation caused by stress concentration, thereby reducing the risk of deformation of the mounting bracket 20. This improves the stability and reliability of the instrument panel reinforcing beam assembly 100, and effectively improves the modal performance of the instrument panel. Furthermore, the cavity structure achieves hollow lightweight by removing internal non-load-bearing materials, reducing weight while maintaining strength, which is beneficial for lightweight vehicle design.

[0025] According to the embodiment of the present utility model, the instrument panel reinforcing beam assembly 100, by setting a reinforcing bracket 30 on the mounting bracket 20, and the reinforcing bracket 30 and the mounting bracket 20 jointly defining the cavity structure, can enhance the structural strength of the mounting bracket 20 and reduce the risk of deformation of the mounting bracket 20 while meeting the requirements of lightweight design. This can reduce vibration and noise during vehicle operation and also help improve the overall performance and fuel economy of the vehicle. According to some embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the mounting bracket 20 with a reinforcing bracket 30 includes: a first connecting plate 21 and a second connecting plate 22 connected along a first direction. The first connecting plate 21 is fixedly connected to the crossbeam body 10. The first connecting plate 21 and the second connecting plate 22 are bent and connected to define an assembly space for the mounting bracket 20. At least a portion of the reinforcing bracket 30 is disposed within the assembly space, and the reinforcing bracket 30 is fixedly connected to the corresponding first connecting plate 21 and second connecting plate 22.

[0026] In some embodiments of this utility model, the first connecting plate 21 and the second connecting plate 22 connected along the first direction can be fixedly connected by welding, or the first connecting plate 21 and the second connecting plate 22 can be integrally formed. However, this utility model is not limited to this. The first connecting plate 21 and the second connecting plate 22 can also be fixedly connected by other means, as long as the first connecting plate 21 and the second connecting plate 22 are connected.

[0027] The first connecting plate 21 is fixedly connected to the crossbeam body 10. In some embodiments of this utility model, the first connecting plate 21 and the crossbeam body 10 can be fixedly connected by welding, or the first connecting plate 21 and the crossbeam body 10 can be fixedly connected by bolts. However, this utility model is not limited to this. The first connecting plate 21 and the crossbeam body 10 can also be fixedly connected by other means, as long as the first connecting plate 21 and the crossbeam body 10 are fixedly connected.

[0028] The first connecting plate 21 and the second connecting plate 22 are bent and connected so that the mounting bracket 20 defines the assembly space. At least a part of the reinforcing bracket 30 is located in the assembly space, which can constrain the displacement freedom of the reinforcing bracket 30, prevent the reinforcing bracket 30 from shifting or twisting under force, and significantly reduce the amount of deformation caused by vibration.

[0029] Furthermore, the reinforcing bracket 30 is fixedly connected to the corresponding first connecting plate 21 and second connecting plate 22. In some embodiments of this utility model, the reinforcing bracket 30 can be fixedly connected to the corresponding first connecting plate 21 and second connecting plate 22 by welding, or the reinforcing bracket 30 can be fixedly connected to the corresponding first connecting plate 21 and second connecting plate 22 by bolts. However, this utility model is not limited to these methods, and the reinforcing bracket 30 can also be fixedly connected to the corresponding first connecting plate 21 and second connecting plate 22 by other means. This utility model takes the welding connection between the reinforcing bracket 30 and the corresponding first connecting plate 21 and second connecting plate 22 as an example for explanation. This forms a cavity structure of "first connecting plate 21 - reinforcing bracket 30 - second connecting plate 22", which can significantly improve the shear and bending stiffness of the mounting bracket 20. The arrangement of the reinforcing bracket 30 can also optimize the load transmission path and reduce the local deformation of the first connecting plate 21 and second connecting plate 22.

[0030] According to some embodiments of the present invention, such as Figure 4 As shown, the reinforcing bracket 30, the first connecting plate 21, and the second connecting plate 22 together define the cavity structure.

[0031] Among them, the reinforcing bracket 30, the first connecting plate 21 and the second connecting plate 22 can jointly define the cavity structure, which is a closed section. This can significantly improve the shear and bending stiffness of the mounting bracket 20. The arrangement of the reinforcing bracket 30 can also optimize the load transmission path, reduce the local deformation of the first connecting plate 21 and the second connecting plate 22, and also improve the stiffness of the force transmission path, further reducing the risk of deformation of the mounting bracket 20, thereby improving the stability and reliability of the instrument panel reinforcing beam assembly 100.

[0032] According to some embodiments of the present invention, such as Figure 4As shown, the reinforcing bracket 30 may include: a first mounting plate 31, a second mounting plate 32, and a third mounting plate 33. The first mounting plate 31 and the third mounting plate 33 are opposite to each other and spaced apart. The second mounting plate 32 is connected between the first mounting plate 31 and the third mounting plate 33, and the first mounting plate 31 and the third mounting plate 33 are located on the same side of the second mounting plate 32. The first mounting plate 31 and the third mounting plate 33 are both fixedly connected to the first connecting plate 21 and the second connecting plate 22. At least a portion of the second mounting plate 32 is spaced apart from the corresponding mounting bracket 20 and fixedly connected to the first connecting plate 21.

[0033] The reinforcing bracket 30 may include a first mounting plate 31, a second mounting plate 32, and a third mounting plate 33. The first mounting plate 31 and the third mounting plate 33 are opposite to each other and spaced apart. The second mounting plate 32 is connected between the first mounting plate 31 and the third mounting plate 33, and the first mounting plate 31 and the third mounting plate 33 are located on the same side of the second mounting plate 32, so that the reinforcing bracket 30 is constructed in a "U" shape or a similar "U" shape. Specifically, the thickness of the reinforcing bracket 30 can be set to 1.2 mm, and the height can be set to 18 mm. These can be reasonably set according to the actual structure of the mounting bracket 20, thereby avoiding interference between the reinforcing bracket 30 and other components.

[0034] Both the first mounting plate 31 and the third mounting plate 33 are fixedly connected to the first connecting plate 21 and the second connecting plate 22. Specifically, the first mounting plate 31 is fixedly connected to both the first connecting plate 21 and the second connecting plate 22, and the third mounting plate 33 is also fixedly connected to both the first connecting plate 21 and the second connecting plate 22. In some embodiments of this utility model, the first mounting plate 31 and the third mounting plate 33 are fixedly connected to the first connecting plate 21 and the second connecting plate 22 by welding, or the first mounting plate 31 and the third mounting plate 33 are fixedly connected to the first connecting plate 21 and the second connecting plate 22 by bolts. However, this utility model is not limited to these methods. The first mounting plate 31 and the third mounting plate 33 can also be fixedly connected to the first connecting plate 21 and the second connecting plate 22 by other means, as long as the first mounting plate 31 and the third mounting plate 33 are fixedly connected to the first connecting plate 21 and the second connecting plate 22. In a specific embodiment of this utility model, the first mounting plate 31 is fixedly connected to the first connecting plate 21 and the second connecting plate 22 by welding, and the third mounting plate 33 is also fixedly connected to the first connecting plate 21 and the second connecting plate 22 by welding. The welding connection enables the reinforcing bracket 30 and the mounting bracket 20 to be seamlessly connected to form an integral structure, which can improve the structural strength at the connection between the mounting bracket 20 and the reinforcing bracket 30, so that the connection between the mounting bracket 20 and the reinforcing bracket 30 can withstand greater tensile stress and shear stress, ensuring the stability of the instrument panel reinforcing beam assembly 100 and avoiding the risk of structural failure due to connection failure.

[0035] At least a portion of the second mounting plate 32 is spaced apart from the corresponding mounting bracket 20 and fixedly connected to the first connecting plate 21, thereby forming a cavity structure between the reinforcing bracket 30 and the mounting bracket 20. The cavity structure, through a partially hollowed-out design, reduces material usage, lowering the overall weight while maintaining structural strength. Furthermore, the cavity structure significantly improves the bending resistance of the mounting bracket 20 by altering the moment of inertia of the cross-section. The cavity structure can absorb and reflect sound waves, reducing vibration noise propagation and thus effectively improving the modal performance of the instrument panel.

[0036] According to some embodiments of the present invention, such as Figure 4 As shown, the first mounting plate 31, the second mounting plate 32 and the third mounting plate 33 each include: a first sub-mounting plate 34 and a second sub-mounting plate 35. The first sub-mounting plate 34 and the second sub-mounting plate 35 are arranged along a first direction. The first sub-mounting plate 34 and the second sub-mounting plate 35 are bent and connected. The first sub-mounting plate 34 is fixedly connected to the first connecting plate 21, and the second sub-mounting plate 35 is fixedly connected to the second connecting plate 22.

[0037] The first sub-mounting plate 34 and the second sub-mounting plate 35 are arranged along a first direction and are bent together. The first sub-mounting plate 34 and the second sub-mounting plate 35 can be integrally formed, or they can be fixedly connected by welding. However, this invention is not limited to this; the first sub-mounting plate 34 and the second sub-mounting plate 35 can also be fixedly connected in other ways, as long as they are bent together. After being connected, the first sub-mounting plate 34 and the second sub-mounting plate 35 can be bent towards the second connecting plate 22 to reduce the distance between them and the second connecting plate 22. This reduces the space occupied by the reinforcing bracket 30 and lowers the risk of interference between the reinforcing bracket 30 and other components. The bent portion of the first sub-mounting plate 34 and the second sub-mounting plate 35 can also serve as an internal reinforcing rib, significantly improving the bending stiffness of the reinforcing bracket 30. The bending structure enables the reinforced bracket 30 to bear loads in both the first direction and the vertical direction (the height direction of the vehicle), making it suitable for complex load conditions.

[0038] And such as Figure 4As shown, the first sub-mounting plate 34 and the first connecting plate 21 are fixedly connected, and the second sub-mounting plate 35 and the second connecting plate 22 are fixedly connected, enabling the reinforcement bracket 30 and the mounting bracket 20 to form an irregular cavity structure. The cavity structure reduces material usage through a partial hollow design, lowering the overall weight while maintaining structural strength. Furthermore, the irregular cavity structure, through its polygonal closed section design, further improves the bending resistance of the mounting bracket 20. The asymmetrical geometry of the irregular cavity can form a natural torque damper, reducing dashboard vibration caused by steering or uneven road surfaces during vehicle operation. The cavity structure can also absorb and reflect sound waves, reducing vibration noise propagation and thus effectively improving the modal performance of the dashboard.

[0039] According to some embodiments of the present invention, such as Figure 4 As shown, the instrument panel reinforcing beam assembly 100 may further include: a connecting structure 40, wherein the connecting structure 40 is connected between the second mounting plate 32 and the second connecting plate 22.

[0040] Specifically, at least a portion of the second mounting plate 32 is spaced apart from the corresponding mounting bracket 20. This means that at least a portion of the second mounting plate 32 is spaced apart from the corresponding second connecting plate 22 of the corresponding mounting bracket 20. A connecting structure 40 connects the second mounting plate 32 and the second connecting plate 22, which can improve the structural strength of the second mounting plate 32, reduce the risk of deformation, and absorb impact energy, reducing the risk of breakage of the second mounting plate 32 of the reinforcing bracket 30. This, in turn, improves the structural strength of the reinforcing bracket 30, the mounting bracket 20, and even the entire instrument panel reinforcing beam. As some embodiments of this utility model, the connecting structure 40 can be a connecting sleeve, connecting column, bolt, or other structure, which can be reasonably selected and set according to actual conditions.

[0041] According to some embodiments of the present invention, such as Figure 4 As shown, the connecting structure 40 can be a connecting sleeve. By fully enclosing the connecting part, the connecting sleeve disperses concentrated stress to a larger contact area, avoiding the risk of fracture caused by localized stress concentration. The contact surface between the sleeve and the connected parts (second mounting plate 32 and second connecting plate 22) can be designed as a smooth transition to reduce fretting wear and crack initiation. The rigid structure of the sleeve can also effectively limit the relative displacement of the connected parts (second mounting plate 32 and second connecting plate 22), improving overall rigidity.

[0042] According to some embodiments of the present invention, such as Figure 2 As shown, the dashboard reinforcement beam assembly 100 may further include: an air conditioning mounting bracket 41, which is fixed to the crossbeam body 10, and has a mounting structure 42 for mounting a glove box.

[0043] In this invention, the air conditioner mounting bracket 41 is fixed to the crossbeam body 10. In some embodiments of this invention, the air conditioner mounting bracket 41 and the crossbeam body 10 can be fixedly connected by welding or by bolts. However, this invention is not limited to these methods. The air conditioner mounting bracket 41 and the crossbeam body 10 can also be fixedly connected by other methods, as long as the air conditioner mounting bracket 41 is fixed to the crossbeam body 10.

[0044] The air conditioning mounting bracket 41 has a mounting structure 42 for mounting a glove box. Specifically, the air conditioning mounting bracket 41 has a mounting structure 42 extending along a first direction (the width direction of the vehicle). The glove box is an instrument panel glove box. The glove box can be formed with mounting holes, clips, and other structures that are adapted to the mounting structure 42. The mounting structure 42 can be snapped into the glove box for assembly. This can add a positioning point to the instrument panel reinforcing beam assembly 100, thereby further improving the deformation resistance of the instrument panel reinforcing beam assembly 100 and effectively improving the NVH performance of the whole vehicle.

[0045] According to some embodiments of the present invention, such as Figure 1 As shown, the dashboard reinforcement beam assembly 100 also includes: a plurality of mounting parts 50, all of which are fixed to the crossbeam body 10, and the plurality of mounting parts 50 are used for fixed assembly with the front of the vehicle, and the number of mounting parts 50 is greater than or equal to three.

[0046] The dashboard reinforcing beam assembly 100 may include two, three, four or more mounting parts 50, but the present invention is not limited thereto. The dashboard reinforcing beam may also include other numbers of mounting parts 50, as long as the dashboard reinforcing beam includes multiple mounting parts 50 and the number of mounting parts 50 is greater than or equal to three.

[0047] As a specific embodiment of this utility model, the dashboard reinforcing beam may include three mounting portions 50. Two mounting portions 50 are collinear and spaced apart. Along the height direction of the vehicle, a third mounting portion 50 is located below the two collinear mounting portions 50, and the third mounting portion 50 may be located in the middle between the two collinear mounting portions 50, so that the three mounting portions 50 are distributed in an isosceles triangle. The three mounting portions 50 distributed in an isosceles triangle form a spatially stable structure with good stability, which can effectively resist loads from different directions. When any side is subjected to force, the other two sides will form a self-balancing system through tension or pressure. The mounting portions 50 distributed in an isosceles triangle can form a multi-path vibration attenuation system, which transmits vibration energy to the vehicle body through different paths, reducing the risk of resonance.

[0048] Furthermore, multiple mounting parts 50 are fixed to the crossbeam body 10. These mounting parts 50 are used for fixed assembly with the front bulkhead of the vehicle, which significantly reduces the deformation of the entire instrument panel reinforcement beam assembly 100 when subjected to loads transmitted from the front bulkhead (such as collision force and vibration). The triangularly distributed mounting parts 50 greatly improve torsional stiffness by constraining the rotational degree of freedom of the reinforcement beam. By adjusting the position and stiffness of the three mounting parts 50, the natural frequency of the instrument panel reinforcement beam assembly 100 can be changed to avoid sensitive frequency bands of engine or road excitation and prevent resonance. In addition, the mounting parts 50 are correspondingly arranged with the steering column, which helps to improve the stability of the steering column area, effectively suppresses steering column displacement and deformation, disperses collision and vibration energy, and reduces vibration and noise.

[0049] The vehicle according to the present invention includes the dashboard reinforcing beam assembly 100 of the above embodiment. By setting a reinforcing bracket 30 on the mounting bracket 20, and the reinforcing bracket 30 and the mounting bracket 20 jointly defining the cavity structure, the structural strength of the mounting bracket 20 can be enhanced while meeting the requirements of lightweight design, and the risk of deformation of the mounting bracket 20 can be reduced. This can reduce vibration and noise during vehicle operation, and also help improve the overall performance and fuel economy of the vehicle.
