[0034] Reference below Figure 1-Figure 7The dashboard reinforcement beam assembly 100 according to an embodiment of the present invention can improve the structural strength of the dashboard reinforcement beam body 1 and the front panel connecting bracket 2, and can transmit the steering force on the steering column from the dashboard reinforcement beam body 1 to the front panel of the vehicle body, thereby improving the overall rigidity of the dashboard reinforcement beam assembly 100, preventing the steering wheel from vibrating when the vehicle is idling or while the vehicle is driving, and improving the driving experience.

[0035] like Figure 1 As shown, an instrument panel reinforcement beam assembly 100 according to one embodiment of the present invention includes: an instrument panel reinforcement beam body 1 and a front wall connecting bracket 2 .

[0036] A steering column mounting area 15 is provided on the rear side of the instrument panel reinforcement beam body 1 , and a reinforcement beam flange 16 is provided on the front side of the instrument panel reinforcement beam body 1 .

[0037] Specifically, the steering column mounting area 15 is used to install the steering column. The steering column mounting area 15 is set on the rear side of the dashboard reinforcement beam body 1, that is, the steering column and the dashboard reinforcement beam body 1 are connected from the rear side of the dashboard reinforcement beam. When the driver turns the steering wheel, the steering force exerted on the steering column can be transmitted to the dashboard reinforcement beam body 1. At the same time, a reinforcement beam flange 16 is set on the front side of the dashboard reinforcement beam body 1 to improve the structural strength of the dashboard reinforcement beam body 1.

[0038] The front panel connecting bracket 2 is provided with a first mounting portion 21 and a second mounting portion 22. The first mounting portion 21 is used to be connected to the front panel of the vehicle body through a first connecting member, and the second mounting portion 22 is connected to the instrument panel reinforcement beam body 1 through a second connecting member 222. The front panel connecting bracket 2 is formed with a front panel flange 23, and the front panel flange 23 is fitted and supported with the reinforcement beam flange 16.

[0039] Specifically, connecting the first mounting portion 21 to the vehicle's front wall allows for connection between the front wall connecting bracket 2 and the vehicle's front wall, enabling installation of the front wall connecting bracket 2 on the vehicle. The front wall connecting bracket 2 is connected to the vehicle's front wall via the first connecting member, resulting in a relatively simple connection. Simultaneously, connecting the second mounting portion 22 to the instrument panel reinforcement beam body 1 allows for connection between the front wall connecting bracket 2 and the instrument panel reinforcement beam body 1, enabling steering force to be transmitted from the instrument panel reinforcement beam body 1 to the front wall connecting bracket 2. The front wall connecting bracket 2 is connected to the instrument panel reinforcement beam body 1 via the second connecting member 222, resulting in a simple and reliable connection. The first connecting member and the second connecting member 222 can both be configured as bolts.

[0040] As well as Figure 4-Figure 5As shown, a front panel flange 23 is formed on the front panel connecting bracket 2 to improve the structural strength of the front panel connecting bracket 2. The front panel flange 23 is constructed to protrude toward the rear side of the vehicle, and the reinforcing beam flange 16 is constructed to protrude toward the front side of the vehicle and extend to the bottom of the front panel flange 23, so that the reinforcing beam flange 16 and the front panel flange 23 can fit and support each other, so that the steering force can be transmitted between the two, and the contact area between the two can be increased, thereby improving the reliability of the steering force transmission between the two. Among them, the front panel flange 23 and the reinforcement beam flange 16 can both be constructed as long strip flanges, that is, both have a large extended length, so that the front panel flange 23 and the reinforcement beam flange 16 have a larger contact area and matching length when in contact and matching, which is beneficial to improving the connection and matching strength between the front panel connecting bracket 2 and the instrument panel reinforcement beam main body 1, and is beneficial to reducing the force at the second connecting member 222, extending the service life of the second connecting member 222, preventing the front panel connecting bracket 2 and the instrument panel reinforcement beam main body 1 from shaking relative to each other around the second connecting member 222, improving the installation stability of the two, and enhancing the user experience.

[0041] Furthermore, the steering column is connected to the instrument panel reinforcement beam body 1, so that the steering force exerted on the steering column can be transmitted to the instrument panel reinforcement beam body 1. At the same time, the instrument panel reinforcement beam body 1 is connected to the front panel connecting bracket 2, so that the steering force can be transmitted to the front panel connecting bracket 2, and the front panel connecting bracket 2 is connected to the front panel of the vehicle body, so that the steering force can be further transmitted to the front panel of the vehicle body. That is, the steering force on the steering column can be transmitted along the instrument panel reinforcement beam body 1 and the front panel connecting bracket 2 to the front panel of the vehicle body, which is beneficial to improving the overall stiffness of the instrument panel reinforcement beam assembly 100.

[0042] Therefore, by setting a steering column mounting area 15 on the rear side of the dashboard reinforcement beam main body 1 to connect the steering column to the dashboard reinforcement beam main body 1, and connecting the dashboard reinforcement beam main body 1 to the front of the vehicle body through the front connecting bracket 2, the steering force on the steering column can be transmitted to the front of the vehicle body along the dashboard reinforcement beam main body 1 and the front connecting bracket 2. At the same time, by setting the reinforcement beam flange 16 and the front connecting bracket 23 to respectively improve the structural strength of the dashboard reinforcement beam main body 1 and the front connecting bracket 2, and fitting the reinforcement beam flange 16 and the front connecting bracket 23 to support them, it can further ensure that the steering force is transmitted from the dashboard reinforcement beam main body 1 to the front connecting bracket 2, and the front of the vehicle body and the dashboard reinforcement beam main body 1 are connected to the front connecting bracket 2 through the first connecting member and the second connecting member 222 respectively.

[0043] According to the dashboard reinforcement beam assembly 100 of an embodiment of the present invention, the structural strength of the dashboard reinforcement beam body 1 and the front panel connecting bracket 2 are respectively improved by providing a reinforcement beam flange 16 and a front panel flange 23. At the same time, a steering column installation area 15 is provided on the dashboard reinforcement beam body 1 to install the steering column, and the front panel connecting bracket 2 is respectively connected to the dashboard reinforcement beam body 1 and the front panel connecting bracket 2, so that the steering force on the steering column can be transmitted to the front panel of the vehicle body along the dashboard reinforcement beam body 1 and the front panel connecting bracket 2, which can improve the overall stiffness of the dashboard reinforcement beam assembly 100, prevent the steering wheel from vibrating when the vehicle is idling or driving, and improve the driving experience. In addition, the front panel of the vehicle body and the dashboard reinforcement beam body 1 are respectively connected to the front panel connecting bracket 2 through the first connecting member and the second connecting member 222. The connection method is simple, reliable and easy to operate.

[0044] In some embodiments, the second mounting portion 22 is located below the first mounting portion 21 , and a first reinforcing rib 211 is provided between the second mounting portion 22 and the first mounting portion 21 .

[0045] Specifically, a first reinforcing rib 211 is provided between the first mounting portion 21 and the second mounting portion 22. The first reinforcing rib 211 can be used to enhance the structural strength between the first mounting portion 21 and the second mounting portion 22, and a steering force transmission channel can be formed between the first mounting portion 21 and the second mounting portion 22, so that the steering force can be transmitted between the first mounting portion 21 and the second mounting portion 22 along the first reinforcing rib 211. At the same time, by arranging the second mounting portion 22 below the first mounting portion 21, the front panel connecting bracket 2 can be spaced apart at the upper and lower positions to connect the front panel connecting bracket 2 to the vehicle body front panel and the instrument panel reinforcement beam body 1, respectively. A steering force transmission channel can be formed in the vertical direction of the vehicle, so that the steering force can be transmitted vertically on the front panel connecting bracket 2, effectively ensuring that the steering force is transmitted from the instrument panel reinforcement beam body 1 connected to the second mounting portion 22 to the vehicle body front panel connected to the first mounting portion 21, that is, from the steering column to the vehicle body front panel, thereby improving the overall rigidity of the instrument panel reinforcement beam assembly 100, preventing steering wheel vibration during vehicle idling or driving, and enhancing the driving experience.

[0046] In some embodiments, there are multiple first mounting portions 21 and multiple second mounting portions 22, and the multiple first mounting portions 21 and the multiple second mounting portions 22 are distributed one-to-one along the vertical direction of the vehicle, and at least one first reinforcing rib 211 is provided between each first mounting portion 21 and the corresponding second mounting portion 22.

[0047] Specifically, the first mounting portion 21 is used to be connected to the front panel of the vehicle body. By providing a plurality of first mounting portions 21, the connection strength between the front panel connecting bracket 2 and the front panel of the vehicle body can be improved. By providing a plurality of first mounting portions 21 at intervals, the front panel connecting bracket 2 can be connected to the front panel of the vehicle body at multiple positions, effectively improving the connection strength between the two, and balancing the forces to avoid stress concentration causing the first connecting member to break and fail. The second mounting portion 22 is used to be connected to the instrument panel reinforcement beam main body 1. By providing a plurality of second mounting portions 22, the connection strength between the front panel connecting bracket 2 and the instrument panel reinforcement beam main body 1 can be improved. By providing a plurality of second mounting portions 22 at intervals, the front panel connecting bracket 2 can be connected to the instrument panel reinforcement beam main body 1 at multiple positions, effectively improving the connection strength between the two, and balancing the forces to avoid stress concentration causing the second connecting member 222 to break and fail.

[0048] At the same time, the plurality of first mounting portions 21 and the plurality of second mounting portions 22 are distributed in a one-to-one correspondence along the vertical direction of the vehicle, so that the number of first mounting portions 21 and the number of second mounting portions 22 are the same. Furthermore, at least one first reinforcing rib 211 is provided between each first mounting portion 21 and the corresponding second mounting portion 22, that is, one, two, or more first reinforcing ribs 211 are provided between each first mounting portion 21 and the corresponding second mounting portion 22, thereby effectively improving the structural strength between the first mounting portion 21 and the second mounting portion 22. The first reinforcing rib 211 is provided below the front dash connecting bracket 2 to effectively improve the structural strength of the front dash connecting bracket 2. Steering force can also be transmitted through the first reinforcing rib 211, thereby ensuring that the steering force is transmitted to the front dash of the vehicle body. The number of first reinforcing ribs 211 can be flexibly set according to actual conditions and space availability.

[0049] In some embodiments, there are multiple first reinforcing ribs 211 between each first mounting portion 21 and the corresponding second mounting portion 22 .

[0050] Specifically, a first reinforcing rib 211 is provided between the first mounting portion 21 and the second mounting portion 22. The first reinforcing rib 211 can be used to connect the first mounting portion 21 and the second mounting portion 22 to improve the structural strength between the first mounting portion 21 and the second mounting portion 22, and to form a steering force transmission channel. A plurality of first reinforcing ribs 211 are provided between each first mounting portion 21 and the corresponding second mounting portion 22, that is, the number of first reinforcing ribs 211 provided between the first mounting portion 21 and the second mounting portion 22 can be two, three or more, so as to effectively improve the structural strength between the first mounting portion 21 and the second mounting portion 22, and to ensure that the steering force is transmitted from the second mounting portion 22 to the first mounting portion 21, and then transmitted from the dashboard reinforcement beam body 1 to the front of the vehicle body.

[0051] One of the plurality of first reinforcing ribs 211 extends from the corresponding first mounting portion 21 to the corresponding second mounting portion 22 .

[0052] Specifically, a plurality of first reinforcing ribs 211 are provided between each first mounting portion 21 and the corresponding second mounting portion 22. By passing one of the plurality of first reinforcing ribs 211 from the corresponding first mounting portion 21 to the corresponding second mounting portion 22, the structural strength between the corresponding first mounting portion 21 and the second mounting portion 22 can be enhanced through the first reinforcing rib 211. At the same time, it can also ensure that the steering force is transmitted between the corresponding first mounting portion 21 and the second mounting portion 22 along the first reinforcing rib 211, thereby enabling the steering force to be transmitted from the instrument panel reinforcement beam body 1 to the front wall of the vehicle body, that is, from the steering column to the front wall of the vehicle body.

[0053] In some embodiments, the first mounting portion 21 is used to connect to the front wall of the vehicle body along the longitudinal direction of the vehicle, and / or the second mounting portion 22 is used to connect to the reinforcing beam flange 16 along the vertical direction of the vehicle.

[0054] Specifically, if Figure 1 、 Figure 3 and Figure 4 As shown, the first mounting portion 21 is used to connect with the front wall of the vehicle body so that the steering force can be transmitted from the front wall connecting bracket 2 to the front wall of the vehicle body. The first mounting portion 21 can be connected to the front wall of the vehicle body along the longitudinal direction of the vehicle so that the steering force can be transmitted along the longitudinal direction of the vehicle. The first mounting portion 21 can be constructed as a mounting hole, and the first connecting member passes through the mounting hole along the longitudinal direction of the vehicle to connect the first mounting portion 21 to the front wall of the vehicle body, so that the steering force can be transmitted from the front wall connecting bracket 2 to the front wall of the vehicle body along the longitudinal direction. At the same time, the second mounting portion 22 is used to connect with the instrument panel reinforcement beam body 1 so that the steering force can be transmitted from the instrument panel to the front wall of the vehicle body. The reinforcing beam body 1 is transmitted to the front panel connecting bracket 2, and the second mounting portion 22 is set on the front panel flange 23, and is connected to the reinforcing beam flange 16 along the vertical direction of the vehicle, so that the steering force can be transmitted from the dashboard reinforcing beam body 1 to the front panel connecting bracket 2 along the vertical direction of the vehicle, and the front panel connecting bracket 2 is connected to the vehicle body front panel and the dashboard reinforcing beam body 1 in the longitudinal and vertical directions of the vehicle respectively, which can improve the connection reliability of the front panel connecting bracket 2, and can transmit the steering force in both the longitudinal and vertical directions of the vehicle, thereby improving the reliability of the steering force transmitted from the steering column to the vehicle body front panel.

[0055] And / or, there are multiple second mounting portions 22 , and the multiple second mounting portions 22 are spaced apart and distributed in the transverse direction of the vehicle, and a second reinforcing rib 221 is provided between two adjacent second mounting portions 22 .

[0056] Specifically, the second mounting portion 22 is used to be connected to the instrument panel reinforcement beam main body 1. The second mounting portion 22 can be set in plurality to improve the connection strength between the front panel connecting bracket 2 and the instrument panel reinforcement beam main body 1. At the same time, the plurality of second mounting portions 22 are set at intervals along the transverse direction of the vehicle, so that the front panel connecting bracket 2 and the instrument panel reinforcement beam main body 1 can be connected at multiple positions at the same time, thereby improving the connection strength and connection reliability between the two, and balancing the force to avoid the second connecting member 222 from breaking and failing due to stress concentration. In addition, a second reinforcing rib 221 is provided between two adjacent second mounting portions 22, so that the second reinforcing rib 221 can be used to connect two adjacent second mounting portions 22, thereby improving the structural strength between the two adjacent second mounting portions 22, and forming a steering force transmission channel between the two adjacent second mounting portions 22, so that the steering force can be transmitted between the two adjacent second mounting portions 22, that is, the steering force can be transmitted on the front panel connecting bracket 2 along the transverse direction of the vehicle.

[0057] In this way, the steering force can be transmitted in the lateral, longitudinal and vertical directions of the vehicle respectively, which can effectively improve the reliability of the steering force transmitted from the steering column to the front of the vehicle body, and further improve the overall stiffness of the dashboard reinforcement beam assembly 100, prevent the steering wheel from vibrating when the vehicle is idling or driving, and improve the driving experience.

[0058] In such Figure 1-Figure 3 In the embodiment shown, two first mounting portions 21 and two second mounting portions 22 are provided, that is, the front panel connecting bracket 2 is connected to the front panel of the vehicle body through the two first mounting portions 21, and the front panel connecting bracket 2 is connected to the instrument panel reinforcement beam body 1 through the two second mounting portions 22, so as to respectively improve the connection strength between the front panel connecting bracket 2 and the front panel of the vehicle body and the instrument panel reinforcement beam body 1, and balance the force to avoid stress concentration causing the first connecting member or the second connecting member 222 to break and fail.

[0060] And, it should be noted that, Figure 6As shown, four second connecting members 222 are spaced apart and arranged behind the dashboard reinforcement beam body 1 to further connect the dashboard reinforcement beam body 1 with the front panel connecting bracket 2, further improve the connection strength between the two, and improve the reliability of the steering force transmitted from the dashboard reinforcement beam body 1 to the front panel connecting bracket 2, and the second connecting members 222 can all use hexagonal flange bolts, and the model can be M6.

[0063] Specifically, if Figure 3 and Figure 7 As shown, the first end region 11 and the second end region 13 are connected by the middle region 12, so that the steering force can be transmitted between the first end region 11, the middle region 12 and the second end region 13, and the first end region 11 and the second end region 13 are both constructed to extend vertically along the vehicle, and the middle region 12 extends transversely along the vehicle, that is, the steering force can be transmitted vertically in the first end region 11 and the second end region 13, and transversely in the middle region 12. At the same time, main body reinforcement ribs are provided in the first end region 11, the middle region 12 and the second end region 13, that is, the main body reinforcement ribs can be used to improve the structural strength of the first end region 11, the middle region 12 and the second end region 13 respectively, thereby effectively improving the structural strength of the instrument panel reinforcement beam body 1, and the main body reinforcement ribs can form a transmission channel for the steering force, so that the steering force can be transmitted along the main body reinforcement ribs, effectively ensuring the transmission of the steering force inside the instrument panel reinforcement beam body 1.

[0065] Specifically, end reinforcement ribs 141 can be provided in the first end region 11 and the second end region 13 to improve the structural strength of the first end region 11 and the second end region 13 through the end reinforcement ribs 141, and the end reinforcement ribs 141 can form a steering force transmission channel to realize the transmission of the steering force in the first end region 11 and the second end region 13, and at least two end reinforcement ribs 141 are provided in the first end region 11 and the second end region 13, that is, the number of end reinforcement ribs 141 in the first end region 11 and the second end region 13 can be two, three or more, so as to effectively improve the structural strength of the first end region 11 and the second end region 13, and the steering force can be transmitted along the end reinforcement ribs 141, that is, the reliability of the transmission of the steering force in the first end region 11 and the second end region 13 is improved.

[0066] At the same time, the ends of two adjacent end reinforcement ribs 141 are bent and connected at a certain angle, so that each two adjacent end reinforcement ribs 141 and the edge of the first end area 11 or the second end area 13 form a triangular structure. The end reinforcement ribs 141 can be used to enhance the structural strength of the first end area 11 and the second end area 13, and the steering force can be transmitted between the end reinforcement ribs 141. Each end reinforcement rib 141 can have a component force in two directions on the plane where it is located, so that the steering force can be transmitted in two directions at the same time, thereby improving the reliability of the steering force transmission in the first end area 11 or the second end area 13.

[0067] And / or, the main reinforcement ribs include a through reinforcement rib 143 and a plurality of middle reinforcement ribs 142 arranged in the middle area 12, the plurality of middle reinforcement ribs 142 are bent and connected in sequence along the length direction of the dashboard reinforcement beam body 1, and the through reinforcement rib 143 penetrates the plurality of middle reinforcement ribs 142.

[0068] Specifically, a central reinforcing rib 142 and a through reinforcing rib 143 are provided in the central region 12. Both the central reinforcing rib 142 and the through reinforcing rib 143 can be used to improve the structural strength of the central region 12, and can form a steering force transmission channel, so that the steering force is transmitted along the central reinforcing rib 142 and the through reinforcing rib 143 in the central region 12. Moreover, a plurality of central reinforcing ribs 142 are provided in the central region 12, which can effectively improve the structural strength of the central region 12 and improve the reliability of the steering force transmission in the central region 12.

[0069] At the same time, by sequentially bending and connecting the multiple central reinforcing ribs 142 along the length of the instrument panel reinforcement beam body 1, each two adjacent central reinforcing ribs 142 form a triangular structure with the edge of the central region 12. This allows each central reinforcing rib 142 to have two components of force in its plane, allowing steering force to be transmitted in two directions simultaneously, further improving the reliability of steering force transmission within the central region 12. Furthermore, by constructing the through reinforcing rib 143 to penetrate multiple central reinforcing ribs 142, the through reinforcing rib 143 connects the multiple central reinforcing ribs 142, allowing steering force to be transmitted between the through reinforcing rib 143 and the multiple central reinforcing ribs 142, thereby effectively improving the reliability of steering force transmission within the central region 12. This ensures the transmission of steering force to the instrument panel reinforcement beam body 1.

[0070] In some embodiments, the steering column mounting area 15 is located between the first end area 11 and the middle area 12 , and one end of the through-rib 143 extends to the second end area 13 and the other end extends to the steering column mounting area 15 .

[0071] Specifically, the steering column mounting area 15 is used to mount the steering column. The steering column mounting area 15 is set between the first end area 11 and the middle area 12, that is, the steering column is set between the first end area 11 and the middle area 12, and is connected to the first end area 11 and the middle area 12 respectively, so that the steering force received by the steering column can be transmitted to the first end area 11 and the middle area 12 at the same time. At the same time, the through reinforcing rib 143 is constructed to extend from the second end area 13 to the steering column mounting area 15, so that the steering column can be mounted between the first end area 11 and the middle area 12. The second end region 13 is connected to the steering column mounting region 15 by using the through reinforcing rib 143, which can improve the structural strength between the second end region 13 and the steering column mounting region 15, and can transmit the steering force from the steering column to the second end region 13 along the through reinforcing rib 143. As a result, the steering force applied to the steering column can be transmitted to the first end region 11, the middle region 12, and the second end region 13 at the same time, thereby improving the transmission efficiency of the steering force and allowing the steering force to be quickly transmitted from the dashboard reinforcement beam body 1 to the front of the vehicle body.

[0072] In some embodiments, at least one transverse reinforcing rib 151 and at least one vertical reinforcing rib 152 are provided in the steering column mounting area 15 , and the transverse reinforcing rib 151 and the vertical reinforcing rib 152 are cross-distributed.

[0073] Specifically, transverse reinforcement ribs 151 and vertical reinforcement ribs 152 are provided in the steering column mounting area 15 to improve the structural strength of the steering column mounting area 15 and form a steering force transmission channel, so that the steering force is transmitted along the transverse reinforcement ribs 151 and the vertical reinforcement ribs 152 respectively, that is, it is transmitted along the transverse and vertical directions of the vehicle in the steering column mounting area 15. At the same time, the number of the transverse reinforcement ribs 151 and the vertical reinforcement ribs 152 is set to at least one, that is, one, two or more, to effectively improve the structural strength of the steering column mounting area and improve the reliability of steering force transmission. In addition, the transverse reinforcement ribs 151 and the vertical reinforcement ribs 152 are cross-distributed, so that the steering force can be transmitted between the transverse reinforcement ribs 151 and the vertical reinforcement ribs 152, thereby improving the reliability of steering force transmission in the steering column mounting area 15.

[0074] For example, Figure 7 As shown, a transverse reinforcement rib 151 and multiple vertical reinforcement ribs 152 are provided in the steering column mounting area 15, which can effectively improve the structural strength of the steering column. The transverse reinforcement rib 151 and the multiple vertical reinforcement ribs 152 are cross-distributed, so that the steering force can be transmitted between the transverse reinforcement rib 151 and the multiple vertical reinforcement ribs 152, thereby improving the reliability of the steering force transmitted from the steering column to the outside.

[0075] And / or, the steering column mounting area 15 is provided with at least two column mounting portions 153 , and a connecting reinforcement rib is provided between two adjacent column mounting portions 153 .

[0076] Specifically, the steering column mounting area 15 is used to mount the steering column. A column mounting portion 153 is provided in the steering column mounting area 15. The instrument panel reinforcement beam body 1 is connected to the steering column through the column mounting portion 153 to achieve the installation of the steering column on the vehicle and to transmit the steering force on the steering column to the instrument panel reinforcement beam body 1. At least two column mounting portions 153 are spaced apart in the steering column mounting area 15, that is, the number of column mounting portions 153 can be two, three or more, so as to improve the connection between the steering column and the instrument panel reinforcement beam body. The connection strength between the reinforcement beam bodies 1 can improve the reliability of the steering force transmitted from the steering column to the dashboard reinforcement beam body 1, and can balance the force. In addition, a connecting reinforcement rib is provided between two adjacent column mounting parts 153, and the two adjacent column mounting parts 153 can be connected by using the connecting reinforcement rib, which can improve the structural strength between the two adjacent column mounting parts 153, and a steering force transmission channel can be formed between the two adjacent column mounting parts 153, so that the steering force is transmitted between the two adjacent column mounting parts 153 along the connecting reinforcement rib.

[0077] For example, Figure 2 and Figure 5As shown, two column mounting portions 153 are provided within the steering column mounting area 15 , and the two column mounting portions 153 are spaced apart in the transverse direction of the vehicle. Thus, the instrument panel reinforcement beam body 1 is connected to the steering column via the two column mounting portions 153 , thereby enhancing the connection strength between the two, balancing the forces, and preventing tilting. The number of column mounting portions 153 is not limited to that described in this embodiment and can be flexibly arranged based on actual conditions and space availability.

[0078] And / or, the dashboard reinforcement beam body 1 and the front panel connecting bracket 2 are both made of magnesium alloy material to meet the lightweight requirements of the vehicle and reduce the installation cost. Among them, the material of the dashboard reinforcement beam body 1 can be AM60B, and the material of the front panel connecting bracket 2 can be AZ91D. The material thickness of the dashboard reinforcement beam body 1 and the front panel connecting bracket 2 can be T, and 2.5mm≤T≤4mm can be made, that is, T can be 2.5mm, 3mm or 4mm, etc.

At the same time, a steering column mounting area 15 is provided on the dashboard reinforcing beam body 1 to install the steering column, and the front panel connecting bracket 2 is respectively connected to the dashboard reinforcing beam body 1 and the front panel connecting bracket 2, so that the steering force on the steering column can be transmitted to the front panel of the vehicle body along the dashboard reinforcing beam body 1 and the front panel connecting bracket 2, which can improve the overall stiffness of the dashboard reinforcing beam assembly 100, prevent the steering wheel from vibrating when the vehicle is idling or driving, and improve the driving experience. In addition, the front panel of the vehicle body and the dashboard reinforcing beam body 1 are respectively connected to the front panel connecting bracket 2 through the first connecting member and the second connecting member 222. The connection method is simple, reliable and easy to operate.
