[0002] The cross-car beam is a core component of a vehicle's front compartment structure, primarily used to support the dashboard, steering system, airbags, and other components, while also providing collision protection and vibration control. As the global automotive industry transitions towards lightweighting, electrification, and sustainable development, lightweighting has become a critical requirement. Industry data shows that a 10% reduction in vehicle weight can improve fuel efficiency by 6%–8% or extend the driving range of electric vehicles by 5%–10%. Currently, the cross-car beams in most vehicles are quite heavy, hindering their installation and indicating room for improvement. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0023] Unless otherwise specified, the front-back direction in this application refers to the longitudinal direction of the vehicle, i.e., the X direction; the left-right direction refers to the lateral direction of the vehicle, i.e., the Y direction; and the up-down direction refers to the vertical direction of the vehicle, i.e., the Z direction.
[0024] The following is for reference. Figures 1-11 The dashboard reinforcing beam 100 according to an embodiment of the present invention can reliably enhance the strength of the reinforcing beam body 1 and reduce the weight of the reinforcing beam body 1, thereby reducing the weight of the dashboard reinforcing beam 100, which is beneficial for installation on a vehicle.
[0025] like Figure 1 As shown, according to one embodiment of the present invention, the instrument panel reinforcing beam 100 includes: a reinforcing beam body 1, a steering column bracket 2, and a plurality of reinforcing beam support plates 3.
[0026] The steering column bracket 2 is connected to the front side of the reinforcing beam body 1; multiple reinforcing beam support plates 3 are respectively connected to the front side of the reinforcing beam body 1. The multiple reinforcing beam support plates 3 are distributed sequentially along the length direction of the reinforcing beam body 1. Each reinforcing beam support plate 3 defines a reinforcing cavity 4 with the reinforcing beam body 1, and the steering column bracket 2 is located between two of the reinforcing beam support plates 3.
[0027] Specifically, the instrument panel reinforcement beam 100 is a core component of the vehicle's front compartment structure, mainly used to support components such as the instrument panel assembly, steering system, and airbags. The instrument panel reinforcement beam 100 includes a reinforcement beam body 1, a steering column bracket 2, and multiple reinforcement beam support plates 3. The reinforcement beam body 1, as the main structure of the instrument panel reinforcement beam 100, provides installation space for other components on the instrument panel reinforcement beam 100. The reinforcement beam body 1 is constructed to extend laterally along the vehicle, allowing it to have a certain length to facilitate the installation of other components. The steering column bracket 2 is used to fix the steering column, providing rigid support for the steering column and preventing it from deforming due to vibration or impact during vehicle operation, thus ensuring the reliability of the steering column.
[0028] By connecting the steering column bracket 2 to the front side of the reinforcing beam body 1, the steering column bracket 2 and the reinforcing beam body 1 can be connected. If the connection can be made by welding or screwing, the connection strength between the two can be improved. In this way, the local stiffness of the reinforcing beam body 1 can be improved by the steering column bracket 2, and the steering column bracket 2 can be fixed to ensure the working reliability of the steering column bracket 2. The steering column bracket 2 and the reinforcing beam body 1 can be distributed and connected in the front-rear direction, and the steering column can be fixed to the front side of the reinforcing beam body 1 by the steering column bracket 2. The steering column bracket 2 and the reinforcing beam body 1 can provide stable mechanical support for the steering column and ensure the stiffness of the installation position of the steering column.
[0029] The reinforcing beam support plate 3 is used to support the reinforcing beam body 1 to improve the strength of the reinforcing beam body 1. Multiple reinforcing beam support plates 3 can be set, that is, two, three or more reinforcing beam support plates 3 can be set together to improve the strength of the reinforcing beam body 1, so as to reliably improve the strength of the reinforcing beam body 1. The multiple reinforcing beam support plates 3 are respectively connected to the front side of the reinforcing beam body 1, that is, the multiple reinforcing beam support plates 3 are respectively connected to the reinforcing beam body 1. For example, the connection can be improved by welding or screwing, which can improve the connection strength between the reinforcing beam support plates 3 and the reinforcing beam body 1. Thus, the strength of the reinforcing beam body 1 can be improved by the reinforcing beam support plates 3. Furthermore, the multiple reinforcing beam support plates 3 can be distributed and connected to the reinforcing beam body 1 in the front direction, so that the reinforcing beam support plates 3 can improve the strength of the reinforcing beam body 1 from the front side.
[0030] Furthermore, the multiple reinforcing beam support plates 3 are sequentially distributed along the length of the reinforcing beam body 1, thus spacing them apart laterally along the vehicle. This allows the multiple reinforcing beam support plates 3 to be connected to different positions on the reinforcing beam body 1, enabling them to simultaneously enhance the strength of the reinforcing beam body 1 at multiple locations. This improves the overall rigidity of the reinforcing beam body 1. Each reinforcing beam support plate 3 defines a reinforcing cavity 4 with the reinforcing beam body 1. The reinforcing cavity 4 is hollow, thus constructing the reinforcing beam body 1 as… The groove shape allows it to have a forward-opening opening. Thus, when the reinforcing beam support plate 3 is connected to the front side of the reinforcing beam body 1, the reinforcing beam support plate 3 can be connected to the open side of the reinforcing beam body 1, so that the reinforcing beam support plate 3 can close the reinforcing beam body 1, thereby improving the modal structure and rigidity of the reinforcing beam body 1. The reinforcing beam support plate 3 and the reinforcing beam body 1 can jointly define the reinforcing cavity 4, which can reduce the weight of the reinforcing beam body 1, thereby reducing the weight of the instrument panel reinforcing beam 100, which is beneficial for the installation of the instrument panel reinforcing beam 100 on the vehicle.
[0031] Furthermore, the steering column bracket 2 and multiple reinforcing beam support plates 3 are all connected to the front side of the reinforcing beam body 1. By placing the steering column bracket 2 between two of the reinforcing beam support plates 3, the steering column bracket 2 and the multiple reinforcing beam support plates 3 can be distributed laterally along the vehicle to avoid interference between the steering column bracket 2 and any one of the reinforcing beam support plates 3, ensuring a reliable connection between the steering column bracket 2 and the reinforcing beam support plates 3 and the reinforcing beam body 1, thereby ensuring their respective operational reliability.
[0032] According to the embodiment of the present utility model, the instrument panel reinforcing beam 100 is constructed by connecting the steering column bracket 2 and multiple reinforcing beam support plates 3 to the front side of the reinforcing beam body 1, and distributing the multiple reinforcing beam support plates 3 sequentially along the length of the reinforcing beam body 1. This allows the steering column bracket 2 and multiple reinforcing beam support plates 3 to be connected to different positions on the reinforcing beam body 1, thereby reliably enhancing the strength of the reinforcing beam body 1 at multiple positions simultaneously. Furthermore, each reinforcing beam support plate 3 defines a reinforcing cavity 4 with the reinforcing beam body 1, which reduces the weight of the reinforcing beam body 1 and consequently reduces the weight of the instrument panel reinforcing beam 100, facilitating its installation on a vehicle.
[0033] In some embodiments, each reinforcing beam support plate 3 is welded to the reinforcing beam body 1; and / or, the steering column bracket 2 is detachably connected to the reinforcing beam body 1 via at least one connector 5.
[0034] Specifically, each reinforcing beam support plate 3 is welded to the reinforcing beam body 1, thus multiple reinforcing beam support plates 3 can be welded to the reinforcing beam body 1 respectively. For example, the connection can be made by hot gas welding, which can improve the connection strength between multiple reinforcing beam support plates 3 and the reinforcing beam body 1. This can improve the reliability of strengthening the reinforcing beam body 1 by multiple reinforcing beam support plates 3. Furthermore, multiple reinforcing beam support plates 3 can be welded to different positions on the reinforcing beam body 1, so that multiple reinforcing beam support plates 3 can simultaneously strengthen the reinforcing beam body 1 at multiple positions, which can effectively improve the overall rigidity of the reinforcing beam body 1.
[0035] Furthermore, the steering column bracket 2 is detachably connected to the reinforcing beam body 1 via at least one connector 5, thereby connecting the steering column bracket 2 and the reinforcing beam body 1 to fix the steering column bracket 2 and ensure its reliable operation. The steering column bracket 2 and the reinforcing beam body 1 can be connected via the connector 5, which can be a bolt or the like, making the connection between the steering column bracket 2 and the reinforcing beam body 1 detachable. This facilitates the connection or separation of the two, as well as the installation or removal of the steering column bracket 2. Consequently, the steering column bracket 2 can be replaced when it fails, reducing subsequent maintenance costs.
[0036] Furthermore, there is at least one connector 5, meaning that the number of connector 5 can be one, two, three, or more. This allows the steering column bracket 2 and the reinforcing beam body 1 to be reliably connected through at least one connector 5. When there are at least two connectors 5, the at least two connectors 5 can be spaced apart so that the steering column bracket 2 and the reinforcing beam body 1 can be connected simultaneously at at least two positions through the at least two connectors 5, thereby improving the reliability and stability of fixing the steering column bracket 2.
[0037] In some embodiments, the reinforcing beam support plate 3 is formed with a first connecting skirt 31 distributed around the reinforcing cavity 4, and the reinforcing beam body 1 is formed with a second connecting skirt 11 distributed around the reinforcing cavity 4; wherein the first connecting skirt 31 and the second connecting skirt 11 are distributed opposite to each other, and at least one of the first connecting skirt 31 and the second connecting skirt 11 is provided with a welding protrusion 111 that is welded to the other.
[0038] Specifically, the reinforcing beam support plate 3 is welded to the reinforcing beam body 1. The reinforcing beam support plate 3 has a first connecting skirt 31 distributed around the reinforcing cavity 4, and the reinforcing beam body 1 has a second connecting skirt 11 distributed around the reinforcing cavity 4. The first connecting skirt 31 and the second connecting skirt 11 are used to provide welding space for the user, so that the first connecting skirt 31 and the second connecting skirt 11 can be welded together to realize the connection between the reinforcing beam support plate 3 and the reinforcing beam body 1. The first connecting skirt 31 and the second connecting skirt 11 are both distributed around the reinforcing cavity 4, so that the first connecting skirt 31 and the second connecting skirt 11 are both constructed to have a certain length along the circumference of the reinforcing cavity 4, thereby increasing the connection length between the reinforcing beam support plate 3 and the reinforcing beam body 1 and improving the connection reliability and connection strength between the two.
[0039] Furthermore, a portion of the reinforcing beam support plate 3 can be extended outward toward the reinforcing cavity 4 to form a first connecting skirt 31, allowing the first connecting skirt 31 to have a certain length in the direction away from the reinforcing cavity 4, thereby increasing the area of the first connecting skirt 31. At the same time, a portion of the reinforcing beam body 1 can be extended outward toward the reinforcing cavity 4 to form a second connecting skirt 11, allowing the second connecting skirt 11 to have a certain length in the direction away from the reinforcing cavity 4, thereby increasing the area of the second connecting skirt 11, so as to facilitate welding the first connecting skirt 31 and the second connecting skirt 11 together.
[0040] The first connecting skirt 31 and the second connecting skirt 11 are distributed opposite to each other, so that the first connecting skirt 31 and the second connecting skirt 11 are directly opposite each other, which facilitates welding of the first connecting skirt 31 and the second connecting skirt 11, thereby facilitating the connection between the reinforcing beam support plate 3 and the reinforcing beam body 1. At least one of the first connecting skirt 31 and the second connecting skirt 11 is provided with a welding protrusion 111 that is welded to the other. The welding protrusion 111 is used to provide a welding position for the user, and the welding protrusion 111 is constructed to have a certain length along a direction perpendicular to the first connecting skirt 31 or the second connecting skirt 11. The welding protrusion 111 can be provided on the first connecting skirt 31 or the second connecting skirt 11, or the welding protrusion 111 can be provided on both the first connecting skirt 31 and the second connecting skirt 11.
[0041] When a welding protrusion 111 is provided on the first connecting skirt 31, the welding protrusion 111 can extend toward the second connecting skirt 11. When a welding protrusion 111 is provided on the second connecting skirt 11, the welding protrusion 111 can extend toward the first connecting skirt 31. In this way, the welding protrusion 111 can be located between the first connecting skirt 31 and the second connecting skirt 11, so that the user can connect the first connecting skirt 31 and the second connecting skirt 11 by welding the welding protrusion 111, thereby realizing the connection between the reinforcing beam support plate 3 and the reinforcing beam body 1.
[0042] For example, such as Figures 5-10 As shown, welding protrusions 111 can be provided on both the first connecting skirt 31 and the second connecting skirt 11, and the welding protrusions 111 on the first connecting skirt 31 and the second connecting skirt 11 can be relatively distributed and close to each other. In this way, the user can connect the reinforcing beam support plate 3 and the reinforcing beam body 1 by welding the welding protrusions 111 on the first connecting skirt 31 and the second connecting skirt 11 together, and the first connecting skirt 31 and the second connecting skirt 11 can ensure uniform contact of the welding surfaces.
[0043] It is understandable that hot gas welding can be used to connect the welding protrusions 111 on the first connecting skirt 31 and the welding protrusions 111 on the second connecting skirt 11. The specific welding process is as follows: The welding protrusions 111 on the first connecting skirt 31 and the welding protrusions 111 on the second connecting skirt 11 are heated simultaneously using a hot gas nozzle until they reach a molten state (usually the temperature is controlled 10℃ to 20℃ above the material's melting point to avoid overheating and degradation). Then, the welding protrusions 111 on the first connecting skirt 31 and the welding protrusions 111 on the second connecting skirt 11 are pressed together, and appropriate pressure is applied (about 0.5MPa to 1MPa, which can be adjusted appropriately according to the material). Finally, wait for natural cooling and solidification to form a strong weld.
[0044] It should be noted that the strength after welding can reach 90% to 100% of the strength of the original material, which is close to the effect of one-piece molding, ensuring that it will not fail under vehicle collision or vibration load.
[0045] In some embodiments, the reinforcing beam body 1 has a first recess 12 and the reinforcing beam support plate 3 has a second recess 32, the first recess 12 and the second recess 32 being open to each other to jointly form a reinforcing cavity 4; or, the reinforcing beam body 1 has a first recess 12 and the reinforcing beam support plate 3 has a closing surface 33, the closing surface 33 closing the first recess 12 to jointly define the reinforcing cavity 4.
[0046] Specifically, the reinforcing beam body 1 and the reinforcing beam support plate 3 can jointly define the reinforcing cavity 4. The reinforcing beam body 1 has a first recess 12, and the reinforcing beam support plate 3 has a second recess 32. The first recess 12 and the second recess 32 are both constructed to be open to each other, so that when the reinforcing beam body 1 and the reinforcing beam support plate 3 are connected, the first recess 12 and the second recess 32 can be spliced together so that the first recess 12 and the second recess 32 can jointly form the reinforcing cavity 4.
[0047] For example, such as Figures 5-6 As shown, both the main body 1 of the reinforcing beam and the support plate 3 of the reinforcing beam can be constructed with a semi-circular cross section. In this way, the main body 1 of the reinforcing beam can form a first sink 12, and the support plate 3 of the reinforcing beam can form a second sink 32. The first sink 12 and the second sink 32 can together form a reinforcing cavity 4. The reinforcing cavity 4 can have a circular cross section, which can provide better torsional stiffness.
[0048] Alternatively, the main body 1 of the reinforcing beam has a first sinkhole 12, and the supporting plate 3 of the reinforcing beam has a closed surface 33. The first sinkhole 12 is configured to open towards the closed surface 33. The closed surface 33 can be configured as a plane, and the area of the closed surface 33 can be larger than the opening area of the first sinkhole 12, so that when the main body 1 of the reinforcing beam is connected to the supporting plate 3 of the reinforcing beam, the closed surface 33 can close the first sinkhole 12, that is, the first sinkhole 12 and the closed surface 33 can together form the reinforcing cavity 4.
[0049] For example, such as Figures 7-8 As shown, the main body 1 of the reinforcing beam can be constructed with a square cross section, and the support plate 3 of the reinforcing beam can be constructed as a flat plate, so that the support plate 3 of the reinforcing beam can form a closed surface 33, thereby allowing the first sink 12 and the closed surface 33 to jointly define the reinforcing cavity 4. The reinforcing cavity 4 can have a trapezoidal cross section, which is convenient for connecting with other components and can enhance the bending resistance.
[0050] It should be noted that in practice, the appropriate cross-sectional shape of the reinforcing cavity 4 can be selected according to the requirements, such as a circle, trapezoid, or ellipse, which can improve the flexibility of the design. Moreover, during the design stage, the stress distribution after welding can be simulated through finite element analysis to further optimize the shape parameters and avoid potential fatigue failure.
[0051] In some embodiments, the steering column support 2 is detachably connected to the reinforcing beam body 1 vertically via at least one connector 5; or, the steering column support 2 is detachably connected to the reinforcing beam body 1 longitudinally via at least one connector 5.
[0052] Specifically, the steering column bracket 2 is detachably connected to the reinforcing beam body 1 vertically via at least one connector 5. This vertical connection between the steering column bracket 2 and the reinforcing beam body 1 secures the steering column bracket 2 and ensures its reliable operation. Furthermore, the connection between the steering column bracket 2 and the reinforcing beam body 1 via at least one connector 5 (such as a bolt) allows for detachable connection, facilitating connection or separation and installation. This enables replacement of the steering column bracket 2 in case of failure, reducing subsequent maintenance costs.
[0053] Alternatively, the steering column bracket 2 can be detachably connected to the reinforcing beam body 1 longitudinally via at least one connector 5. This connection along the vehicle's longitudinal direction secures the steering column bracket 2 and ensures its reliable operation. Furthermore, the connection between the steering column bracket 2 and the reinforcing beam body 1 via at least one connector 5 (such as a bolt) allows for detachable connection, facilitating connection or separation and installation. This also allows for easy replacement of the steering column bracket 2 in case of failure, reducing future maintenance costs.
[0054] In such Figure 4 In the embodiment shown, there are three connectors 5. The three connectors 5 are respectively connected to the rear, top, and bottom of the steering column bracket 2, so that the three connectors 5 are distributed at intervals. Then, the steering column bracket 2 can be connected to the reinforcing beam body 1 at three positions spaced apart along the vertical and longitudinal directions of the vehicle through the three connectors 5. The steering column bracket 2 can be reliably fixed to ensure its working reliability. In practice, local reinforcing rings or metal inserts can be added around the connectors 5 to prevent material creep.
[0055] In some embodiments, the reinforcing beam body 1 is provided with a plurality of intersecting first reinforcing ribs 13 in the reinforcing cavity 4; and / or, the reinforcing beam support plate 3 is provided with a plurality of intersecting second reinforcing ribs 34 on the surface facing outward of the reinforcing cavity 4; and / or, the reinforcing beam support plate 3 is provided with support ribs 35 on the surface facing inward of the reinforcing cavity 4, and the support ribs 35 are supported on the inner surface of the reinforcing cavity 4.
[0056] Specifically, the reinforcing beam body 1 is provided with multiple intersecting first reinforcing ribs 13 within the reinforcing cavity 4. The first reinforcing ribs 13 are disposed within the reinforcing cavity 4 to support the reinforcing beam body 1 from the inside, thereby improving the strength of the reinforcing beam body 1 and enhancing its resistance to bending, torsion, and compression. This prevents a significant decrease in the strength of the reinforcing beam body 1 due to the formation of the reinforcing cavity 4. The first reinforcing ribs 13 are provided in multiple ways, such as in a cross shape or a grid pattern, so that the multiple first reinforcing ribs 13 can simultaneously support the reinforcing beam body 1 at multiple locations within the reinforcing cavity 4, thereby effectively improving the strength of the reinforcing beam body 1.
[0057] It should be noted that, as Figure 9 and Figure 11 As shown, multiple spaced-apart support columns 36 are provided on the surface of the reinforcing beam support plate 3 facing the reinforcing cavity 4. The support columns 36 are distributed opposite to the first reinforcing rib 13. When the reinforcing beam body 1 and the reinforcing beam support plate 3 are welded together, the support columns 36 and the first reinforcing rib 13 can also be welded together to support the reinforcing beam body 1 and the reinforcing beam support plate 3 inside the reinforcing cavity 4, so as to effectively improve the overall strength and improve noise and vibration characteristics.
[0058] The diameter and height of the support column 36 must match the size of the first reinforcing rib 13 (e.g., the diameter can be 5-10 mm). The vertical distance between the highest and lowest support column 36 among the multiple support columns 36 must be greater than 80% of the vertical height of the reinforcing cavity 4 to provide sufficient support strength. The support column 36 and the first reinforcing rib 13 can also be connected by hot gas welding. After welding, the strength of the reinforcing beam body 1 can be enhanced from the inside of the reinforcing cavity 4, which can improve the support function of the reinforcing beam support plate 3 and increase the natural frequency of the reinforcing beam body 1 by 15%-25%, reducing the risk of low-frequency resonance.
[0059] Meanwhile, multiple intersecting second reinforcing ribs 34 can be provided on the surface of the reinforcing beam support plate 3 facing outward from the reinforcing cavity 4. The second reinforcing ribs 34 are provided on the reinforcing beam support plate 3 to support the reinforcing beam support plate 3, thereby improving the strength of the reinforcing beam support plate 3 and thus improving the working reliability of the reinforcing beam support plate 3. The number of second reinforcing ribs 34 can be two, three or more, so that the strength of the reinforcing beam support plate 3 can be improved by the multiple second reinforcing ribs 34 working together. The multiple second reinforcing ribs 34 are intersecting on the reinforcing beam support plate 3, such as in a cross shape or a grid pattern, so that the multiple second reinforcing ribs 34 can support the reinforcing beam support plate 3 at multiple positions on the reinforcing beam support plate 3 at the same time, thereby effectively improving the strength and working reliability of the reinforcing beam support plate 3.
[0060] Furthermore, the surface of the reinforcing beam support plate 3 facing the inner surface of the reinforcing cavity 4 is provided with a support rib 35, and the support rib 35 is supported on the inner surface of the reinforcing cavity 4. The support rib 35 can extend towards the interior of the reinforcing cavity 4, so that the support rib 35 can approach the reinforcing beam body 1 and have a certain length. In this way, when the reinforcing beam body 1 is connected to the reinforcing beam support plate 3, the support rib 35 can support the reinforcing beam body 1 from the interior of the reinforcing cavity 4, so as to further improve the strength of the reinforcing beam body 1 and enhance the bending, torsion and compressive resistance of the reinforcing beam body 1.
[0061] like Figures 10-11 As shown, multiple support ribs 35 are provided, and the multiple support ribs 35 are spaced apart along the length direction of the reinforcing beam body 1, so that the multiple support ribs 35 can support the reinforcing beam body 1 at multiple positions at the same time. Moreover, the reinforcing beam body 1 is constructed with a trapezoidal cross section, and the support ribs 35 have a certain height in the vertical direction, which can support the two inner surfaces of the reinforcing cavity 4 distributed in the vertical direction. The longitudinal extension length of the support ribs 35 is more than half of the longitudinal depth of the reinforcing cavity 4, such as occupying 60% to 70% of the longitudinal depth of the reinforcing cavity 4, to ensure effective contact and load transfer. The first reinforcing rib 13 can support the longitudinal inner surface of the reinforcing cavity 4, which can effectively improve the strength and rigidity of the reinforcing beam body 1.
[0062] In some embodiments, the reinforcing beam body 1 is formed with a forward-opening mounting groove 14, and at least a portion of the steering column support 2 extends into the mounting groove 14 to be inserted into the reinforcing beam body 1.
[0063] Specifically, the steering column bracket 2 is connected to the front side of the reinforcing beam body 1. A forward-opening mounting groove 14 is formed on the reinforcing beam body 1. The mounting groove 14 provides an installation position for the steering column bracket 2. The mounting groove 14 is recessed to the rear and has a large internal space to provide a space for the steering column bracket 2. Thus, part or all of the steering column bracket 2 can be extended into the mounting groove 14, so that the steering column bracket 2 and the reinforcing beam body 1 can be plugged and connected. After at least part of the steering column bracket 2 is extended into the mounting groove 14, the steering column bracket 2 and the reinforcing beam body 1 can partially overlap to increase the connection area between the two. This facilitates the connection between the reinforcing beam body 1 and the steering column bracket 2, and reliably fixes the steering column bracket 2.
[0064] It should be noted that, as Figure 1 , Figure 2 and Figure 4 As shown, part of the steering column bracket 2 can be extended into the mounting groove 14, and then the steering column bracket 2 can be detachably connected to the reinforcing beam body 1 through the connector 5. This enables reliable installation of the steering column bracket 2, ensuring its reliable operation, and facilitates the installation or removal of the steering column bracket 2, so that it can be replaced when it fails, thereby reducing the later maintenance cost.
[0065] In some embodiments, the reinforcing beam support plate 3 includes a first support plate 37, an intermediate support plate 38, and a second support plate 39 distributed sequentially along the length of the reinforcing beam body 1. The steering column support 2 is located between the first support plate 37 and the intermediate support plate 38. The reinforcing beam body 1 is also provided with a reinforcing region 15 between the intermediate support plate 38 and the second support plate 39. The reinforcing region 15 is provided with a plurality of cross-distributed third reinforcing ribs 16.
[0066] Specifically, there are multiple reinforcing beam support plates 3, including a first support plate 37, an intermediate support plate 38, and a second support plate 39 distributed sequentially along the length of the reinforcing beam body 1. That is, there are three reinforcing beam support plates 3, and the three reinforcing beam support plates 3 are distributed sequentially along the length of the reinforcing beam body 1. They can support the reinforcing beam body 1 at three positions at the same time to reliably enhance the strength of the reinforcing beam body 1, which is sufficient to cope with the dynamic load and vibration during vehicle operation. Moreover, the steering column bracket 2 is located between the first support plate 37 and the intermediate support plate 38, so that the steering column bracket 2 and the three reinforcing beam support plates 3 are evenly distributed to avoid interference, improve their respective working reliability, and enable the steering column bracket 2 and the three reinforcing beam support plates 3 to support the reinforcing beam body 1 at the same time to enhance the strength of the reinforcing beam body 1.
[0067] Furthermore, there is a certain distance between the intermediate support plate 38 and the second support plate 39, meaning that the portion of the reinforcing beam body 1 located between the intermediate support plate 38 and the second support plate 39 is open to the front. Additionally, the reinforcing beam body 1 has a reinforcing region 15 between the intermediate support plate 38 and the second support plate 39. Multiple intersecting third reinforcing ribs 16 are provided within the reinforcing region 15 to support the reinforcing beam body 1, thereby increasing the strength of the reinforcing beam body 1 and enhancing the reinforcing beam. The main body 1 has good resistance to bending, torsion and compression, and multiple third reinforcing ribs 16 are provided, that is, the number of third reinforcing ribs 16 can be two, three or more, so that the strength of the main body 1 can be improved by multiple third reinforcing ribs 16. The multiple third reinforcing ribs 16 are distributed crosswise in the reinforcement area 15, such as in a star-shaped distribution or radial distribution, so that multiple third reinforcing ribs 16 can simultaneously support the main body 1 at multiple positions in the reinforcement area 15, which can effectively avoid stress concentration and improve the strength of the main body 1.
[0068] It should be noted that, as Figure 1 As shown, the first support plate 37, the middle support plate 38, and the second support plate 39 are distributed sequentially in the left-right direction. The first support plate 37 is located on the far left, and the second support plate 39 is located on the far right. The steering column bracket 2 can be installed at the driver's seat of the vehicle, and the reinforcing area 15 is set at the passenger seat of the vehicle. The passenger seat area has lower strength requirements for the main body of the reinforcing beam 1. The reinforcing beam support plate 3 is not set here, which can reduce the number of components, reduce the difficulty of operation and the cost of setting. In addition, the third reinforcing rib 16 is distributed in a star shape, which can increase the local stiffness of the area by about 20% to 30% without significantly increasing the amount of material used.
[0069] In some embodiments, at least one of the reinforcing beam body 1, the steering column bracket 2, and the reinforcing beam support plate 3 is made of plastic; and / or, a plurality of load-bearing brackets 17 are also provided on the rear side of the reinforcing beam body 1, the load-bearing brackets 17 being used to connect to external components.
[0070] Specifically, at least one of the reinforcing beam body 1, steering column bracket 2, and reinforcing beam support plate 3 is made of plastic. This means that one of the reinforcing beam body 1, steering column bracket 2, and reinforcing beam support plate 3 can be made of plastic, or two of the reinforcing beam body 1, steering column bracket 2, and reinforcing beam support plate 3 can be made of plastic, or all of the reinforcing beam body 1, steering column bracket 2, and reinforcing beam support plate 3 can be made of plastic. This reduces the weight of the instrument panel reinforcing beam 100 and meets the vehicle's lightweight requirements.
[0071] And, as Figures 2-3As shown, multiple support brackets 17 can be installed on the rear side of the reinforcing beam body 1. The support brackets 17 are used to connect with external components to install the external components and ensure their reliable operation. There are multiple support brackets 17, that is, the number of support brackets 17 can be two, three or more. This allows the reinforcing beam body 1 to install multiple external components simultaneously through multiple support brackets 17. For example, it can be used to install the instrument panel assembly, central control screen, air conditioner and passenger airbag. By setting multiple support brackets 17 on the rear side of the reinforcing beam body 1, the support brackets 17 and the steering column bracket 2 can be spaced apart to avoid interference and improve their respective operational reliability.
[0072] In such Figures 1-11 In the illustrated embodiment, the reinforcing beam body 1, steering column bracket 2, and reinforcing beam support plate 3 are all made of plastic material. For example, high-strength engineering plastics can be used to form an all-plastic instrument panel reinforcing beam 100, which can effectively reduce the overall weight of the instrument panel reinforcing beam 100 and facilitate its installation on the vehicle. The instrument panel reinforcing beam 100 can be made by injection molding, that is, the reinforcing beam body 1, steering column bracket 2, and reinforcing beam support plate 3 can be made by injection molding respectively, so that multiple load-bearing brackets 17 can be integrated on the reinforcing beam body 1, so that the reinforcing beam body 1 and the load-bearing brackets 17 can be integrally molded, which can reduce the number of parts, reduce the difficulty of operation, improve production efficiency, reduce demolding difficulty, improve manufacturing accuracy (tolerance can be controlled within ±0.5mm), and facilitate mold adjustment and iteration.
[0073] The all-plastic dashboard reinforcing beam 100 of this utility model has high strength and rigidity, and its cost can be reduced by about 45% compared with magnesium-aluminum alloy dashboard reinforcing beams, giving it a good market advantage. Compared with metal materials, the overall weight can be reduced by more than 20%, which has the advantages of lightweighting and environmental protection. Moreover, by taking advantage of the natural damping properties of plastic (vibration attenuation rate is 20% to 30% higher than that of metal), it can improve NVH performance, reduce noise transmission (noise level is reduced to below 60dB), and enhance the ride comfort of the vehicle.
[0074] Furthermore, the thickness of the first reinforcing rib 13 and the second reinforcing rib 34 should match the thickness of the main body of the reinforcing beam 1 to ensure that the material flowability and demolding are not affected during the injection molding process.
[0075] This utility model also proposes a vehicle.
[0076] The vehicle according to the embodiments of this utility model includes the dashboard reinforcing beam 100 of any of the above embodiments. By making the reinforcing beam body 1, the steering column bracket 2, and the multiple reinforcing beam support plates 3 all made of plastic, the overall weight can be effectively reduced, which is beneficial for installation on the vehicle and meets the vehicle's lightweight requirements. Furthermore, by setting the first reinforcing rib 13, the second reinforcing rib 34, and the support rib 35, the overall rigidity and strength can be improved, which is beneficial for reducing material thickness, overall weight, and installation costs, and thus improving user satisfaction.
