Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle technology, and more specifically, to a steering support beam structure and a vehicle. Background Technology
[0002] As living standards improve, users have increasingly higher demands for the comfort of car driving. When a car is driving on the road, it receives excitations from various sources, including the road surface and the engine. Road excitations act on the tires and are transmitted to the body through the suspension, easily causing vibrations in the body panels. These vibrations may be localized to the body panels or caused by the vibration modes of the body frame. These vibrations are transmitted along the body to the steering wheel, pedals, seats, floor, and other areas that come into direct contact with the occupants. Among these, steering wheel vibration is one of the issues that drivers are most concerned about and most sensitive to, directly affecting the driving experience and safety of the occupants.
[0003] For steering wheel vibration control, the most common methods are to increase the suspension vibration isolation rate and improve the steering system mode. The steering support beam structure, which is connected to the A-pillar and front bulkhead of the vehicle body, plays a decisive role in the steering system mode. Therefore, the steering support beam structure needs to be strong and has a good design structure to achieve good performance. Good design structure and performance are often proportional to weight, which can easily lead to simultaneous improvement in performance and weight.
[0004] To address this, the current approach is to use a "plastic-coated steel" process to achieve lightweight design of the steering support beam structure. This involves embedding steel plates inside the steering support beam and wrapping it with plastic, aiming to achieve both high performance and low weight in automotive steering supports. However, since steering support beam structures using the "plastic-coated steel" process often employ a one-piece molding technology, it not only has high process requirements but also results in a complex, irregularly shaped steering support beam structure that occupies a large amount of space and is inconvenient to transport.

[0030] Combination Figure 1 , Figure 2 and Figure 5 As shown, this utility model embodiment provides a steering support beam structure, including a first connecting mechanism 2 and a crossbeam 1. The crossbeam 1 is detachably connected to the A-pillar of the vehicle body. One end of the first connecting mechanism 2 is detachably connected to the crossbeam 1, and the other end is detachably connected to the front bulkhead of the vehicle body.
[0031] In this embodiment, the steering support beam structure is used at least to support the vehicle's A-pillar and front bulkhead (i.e., the partition between the vehicle's engine compartment and passenger compartment), thereby improving the vehicle's structural stability. The crossbeam 1 (CCB, or crosscar beam; also known as the instrument panel crossbeam or transverse body support beam) of the steering support beam structure is connected to the vehicle's A-pillar and serves as an important support component for the instrument panel and steering system, playing a role in load-bearing, fixing, and strengthening the overall vehicle rigidity. The crossbeam 1 is detachably connected to the vehicle's A-pillar. For example, the two ends of the crossbeam 1, which is arranged transversely along the vehicle, are detachably connected to the two A-pillars of the vehicle body. This improves the convenience of installing or removing the crossbeam 1 from the vehicle body, increases the flexibility of vehicle assembly, simplifies the structure of the crossbeam 1, and avoids the problems of complex structure, increased space occupation, and inconvenient transportation caused by integrating the crossbeam 1 with the A-pillar. This reduces the manufacturing difficulty of the steering support beam structure and improves its transportation convenience. The first connecting mechanism 2 of the steering support beam structure is used to connect the crossbeam 1 to the front bulkhead of the vehicle body, achieving a stable connection between the corresponding components of the vehicle body and strengthening the overall vehicle rigidity. Furthermore, one end of the first connecting mechanism 2 is detachably connected to the crossbeam 1, and the other end is detachably connected to the front bulkhead of the vehicle body. On the one hand, this improves the convenience of installation or disassembly of the crossbeam 1 and the first connecting mechanism 2, enhances the flexibility of vehicle production, assembly, and maintenance, and reduces the cost of subsequent maintenance and replacement of the steering support beam structure. On the other hand, it avoids the formation of a complex irregular structure due to the integration of the crossbeam 1 and the first connecting mechanism 2, which would lead to increased production costs, increased difficulty, and increased space occupation. This allows the steering support beam structure to be disassembled into multiple independent components for production, assembly, and transportation, greatly reducing the manufacturing difficulty of the steering support beam structure and improving the transportation convenience of the steering support beam structure. Furthermore, compared to the integrated steering support beam structure with a specific shape in related technologies, which is only applicable to specific vehicle models, the components of the steering support beam structure in this embodiment can be designed as universal structures, realizing the modular design of the steering support beam structure. A specific shape structure can be achieved through the combination of different components. In other words, the components of the steering support beam structure can be used for different vehicle models. Each component can be flexibly selected and combined according to the needs of a specific vehicle model, thereby avoiding the need to customize the steering support beam structure for each vehicle model, reducing the complexity and cost of the related production process, and facilitating subsequent production adjustments and upgrades (such as adjusting and upgrading a certain component of the steering support beam structure to achieve the adjustment and upgrade of the steering support beam structure).
[0032] In summary, the steering support beam structure, through the detachable connection of the crossbeam 1 to the vehicle's A-pillar and front bulkhead, provides support for the A-pillar and front bulkhead when connected, thus improving the overall structural stability of the vehicle. Furthermore, the detachable connection allows the steering support beam structure to be disassembled into multiple independent components for manufacturing, assembly, transportation, and maintenance, significantly reducing manufacturing complexity and improving transportation convenience. In addition, compared to an integrated structure, the steering support beam structure in this embodiment adopts a modular design. The components of the steering support beam structure can be flexibly selected and combined according to different vehicle models, avoiding the complexity and high cost of customized production, improving the applicability of each component, and facilitating future adjustments and upgrades.
[0033] Optionally, combined Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the first connecting mechanism 2 includes a steering bracket 21 for mounting the vehicle's steering system. One end of the steering bracket 21 is detachably connected to the crossbeam 1, and the other end is detachably connected to the front bulkhead.
[0034] In this embodiment, the first connecting mechanism 2 of the steering support beam structure includes a steering bracket 21. On the one hand, the steering bracket 21 serves as a connecting medium between the crossbeam 1 and the front bulkhead of the vehicle body. Its two ends are detachably connected to the crossbeam 1 and the front bulkhead, respectively, to ensure the stability of the connection between the front bulkhead and the crossbeam 1 through the steering bracket 21, and to facilitate the installation or disassembly of the front bulkhead, the crossbeam 1, and the steering bracket 21, thereby improving the convenience of the steering support beam structure and the assembly and subsequent maintenance of the front bulkhead. On the other hand, the steering bracket 21 is used to set up the vehicle's steering system, such as to provide support for the steering column of the vehicle's steering system, to ensure the rigidity and stability of the steering column during the steering process, etc., which helps to optimize the control of steering wheel vibration and ensure the normal and stable operation of the vehicle's steering system.
[0035] For example, combined Figure 1 , Figure 4 As shown, the steering bracket 21 may be generally trapezoidal, including a generally parallel long frame and a short frame. The long frame is connected to the crossbeam 1 by bolts (or other fasteners), and the short frame is connected to the front bulkhead by bolts (or other fasteners).
[0036] Optionally, combined Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the first connecting mechanism 2 also includes a connecting bracket 22, one end of which is detachably connected to the crossbeam 1 and the other end is detachably connected to the front bulkhead; and the connecting bracket 22 is located on at least one side of the steering bracket 21.
[0037] In this embodiment, since the crossbeam 1 and the front bulkhead are connected by the steering bracket 21 of the first connecting mechanism 2, to further improve the structural strength of the entire vehicle, the first connecting mechanism 2 is also provided with a connecting bracket 22. Both ends of the connecting bracket 22 are connected to the crossbeam 1 and the front bulkhead respectively, to further improve the stability of the connection between the crossbeam 1 and the front bulkhead, thereby improving the structural strength of the entire vehicle and enhancing the vehicle's safety and reliability. Furthermore, the two ends of the connecting bracket 22 are detachably connected to the crossbeam 1 and the front bulkhead, improving the convenience of installation or disassembly between the connecting bracket 22, the crossbeam 1, and the front bulkhead, and enhancing the convenience of the steering support beam structure and the assembly and subsequent maintenance of the front bulkhead.
[0038] Furthermore, on the crossbeam 1, the connecting bracket 22 is located on at least one side of the steering bracket 21. For example, in the extending direction of the crossbeam 1, the connecting bracket 22 is provided on one side of the steering bracket 21, or connecting brackets 22 are provided on opposite sides of the steering bracket 21. In this way, on the one hand, the connecting bracket 22 and the steering bracket 21 provide support between the crossbeam 1 and the front bulkhead, enhancing the stability when the crossbeam 1 and the front bulkhead are connected by the connecting bracket 22 and the steering bracket 21; on the other hand, the connecting bracket 22 and the steering bracket 21 increase the (indirect) contact area between the crossbeam 1 and the front bulkhead, which can effectively disperse and transmit the force generated by the vehicle under collision or impact, improve the impact resistance of the whole vehicle structure, enhance the rigidity and safety of the body, and reduce the stress concentration of the steering bracket 21 used to connect the crossbeam 1 and the front bulkhead, avoiding deformation or damage to the steering bracket 21 due to excessive local pressure, effectively extending the service life of the steering bracket 21, thereby ensuring that the steering bracket 21 can be used normally for supporting and fixing the steering system.
[0039] For example, the connecting bracket 22 extends generally along the longitudinal direction of the vehicle, with its front end connected to the front bulkhead by bolts (or other fasteners) and its rear end connected to the crossbeam 1 by bolts (or other fasteners).
[0040] Specifically, considering the detachable connections between the corresponding components of the steering support beam structure, it is considered a movable component. The first connecting mechanism 2 connects the crossbeam 1 to the front bulkhead. The structural stiffness of the first connecting mechanism 2 affects the supporting stiffness of the crossbeam 1, thus influencing the vehicle's steering system modes. Therefore, the steering bracket 21 and connecting bracket 22 of the first connecting mechanism 2 can be modified in terms of structure, material, and quantity according to different performance requirements, thereby adapting to different vehicle needs. Furthermore, it facilitates disassembly and verification in subsequent real-vehicle testing, offering cost reduction, feasibility, and high compatibility.
[0041] Optionally, combined Figures 2-4As shown, the steering bracket 21 includes a first bracket body 211, a first connecting part 212 and a second connecting part 213. One end of the first bracket body 211 is detachably connected to the front bulkhead, and the other end extends toward the crossbeam 1. The first connecting part 212 and the second connecting part 213 are both located at the end of the first bracket body 211 extending toward the crossbeam 1, and the first connecting part 212 and the second connecting part 213 together form a first receiving groove 21a for accommodating the crossbeam 1. The crossbeam 1 is detachably connected to the first connecting part 212 and the second connecting part 213 at the first receiving groove 21a by fasteners.
[0042] In this embodiment, the steering bracket 21 includes a first bracket body 211, a first connecting portion 212, and a second connecting portion 213. One end of the first bracket body 211 is detachably connected to the front bulkhead, and the other end is disposed towards the crossbeam 1. The first connecting portion 212 and the second connecting portion 213 are disposed at the end of the first bracket body 211 facing the crossbeam 1, and the first connecting portion 212 and the second connecting portion 213 are connected to form a first receiving groove 21a for accommodating the crossbeam 1. The crossbeam 1 is detachably connected to the first connecting portion 212 and the second connecting portion 213 at the first receiving groove 21a, respectively, to increase the contact area between the steering bracket 21 and the crossbeam 1 and improve the stability when the steering bracket 21 and the crossbeam 1 are connected. The crossbeam 1 is detachably connected to the first connecting portion 212 and the second connecting portion 213 at the first receiving groove 21a by fasteners to improve the connection stability when the steering bracket 21 and the crossbeam 1 are connected, and to improve the convenience of disassembling the steering bracket 21 and the crossbeam 1.
[0043] For example, the first connecting portion 212 and the second connecting portion 213 are arranged at an angle to form a first receiving groove 21a. When the crossbeam 1 is connected to the first connecting portion 212 and the second connecting portion 213 at the first receiving groove 21a by fasteners, the side of the first connecting portion 212 facing the crossbeam 1 serves as one groove wall of the first receiving groove 21a and is stably in contact (e.g., in close contact) with one side of the crossbeam 1, and the side of the second connecting portion 213 facing the crossbeam 1 serves as the other groove wall of the first receiving groove 21a and is stably in contact with the other side of the crossbeam 1. This allows the steering bracket 21 and the crossbeam 1 to have a large contact area, facilitating the connection of the steering bracket 21 and the crossbeam 1 by multiple fasteners, and facilitating the detachable connection of the first connecting portion 212 and the second connecting portion 213 to the crossbeam 1 by fasteners. Specifically, the first connecting portion 212 and the second connecting portion 213 can respectively contact and connect with two adjacent sides of the crossbeam 1, achieving stable and reliable connection performance through a simple connecting portion design.
[0044] Optionally, combined Figures 5-7As shown, the connecting bracket 22 includes a second bracket body 221, a third connecting part 222 and a fourth connecting part 223. One end of the second bracket body 221 is detachably connected to the front panel, and the other end extends toward the crossbeam 1. The third connecting part 222 and the fourth connecting part 223 are both located at the end of the second bracket body 221 that extends toward the crossbeam 1, and the third connecting part 222 and the fourth connecting part 223 together form a second receiving groove 22a for accommodating the crossbeam 1. The crossbeam 1 is detachably connected to the third connecting part 222 and the fourth connecting part 223 at the second receiving groove 22a by fasteners.
[0045] In this embodiment, the connecting bracket 22 includes a second bracket body 221, a third connecting portion 222, and a fourth connecting portion 223. One end of the second bracket body 221 is detachably connected to the front panel, and the other end faces the crossbeam 1. The third connecting portion 222 and the fourth connecting portion 223 are located at the end of the second bracket body 221 facing the crossbeam 1, and are connected to each other to form a second receiving groove 22a for accommodating the crossbeam 1. The crossbeam 1 is detachably connected to the third connecting portion 222 and the fourth connecting portion 223 at the second receiving groove 22a, thereby increasing the contact area between the connecting bracket 22 and the crossbeam 1 and improving the stability of the connection between the connecting bracket 22 and the crossbeam 1. The crossbeam 1 is detachably connected to the third connecting portion 222 and the fourth connecting portion 223 at the second receiving groove 22a by fasteners, thereby improving the connection stability of the connecting bracket 22 and the crossbeam 1 and the ease of disassembling the connecting bracket 22 and the crossbeam 1.
[0046] For example, the third connecting portion 222 and the fourth connecting portion 223 are arranged at an angle to form a second receiving groove 22a. When the crossbeam 1 is connected to the third connecting portion 222 and the fourth connecting portion 223 at the second receiving groove 22a by fasteners, the side of the third connecting portion 222 facing the crossbeam 1 serves as one groove wall of the second receiving groove 22a and is stably in contact (e.g., in close contact) with one side of the crossbeam 1, and the side of the fourth connecting portion 223 facing the crossbeam 1 serves as the other groove wall of the second receiving groove 22a and is stably in contact with the other side of the crossbeam 1. This allows the connecting bracket 22 and the crossbeam 1 to have a large contact area, facilitating the connection of the connecting bracket 22 and the crossbeam 1 by multiple fasteners, and facilitating the detachable connection of the third connecting portion 222 and the fourth connecting portion 223 to the crossbeam 1 by fasteners. Specifically, the third connecting portion 222 and the fourth connecting portion 223 can respectively contact and connect with two adjacent sides of the crossbeam 1, achieving stable and reliable connection performance through a simple connecting portion design.
[0047] Optionally, combined Figure 1 , Figure 2 and Figure 5As shown, the steering support beam structure also includes a second connecting mechanism 3, one end of which is detachably connected to the crossbeam 1, and the other end is detachably connected to the vehicle floor.
[0048] In this embodiment, the steering support beam structure also includes a second connecting mechanism 3. The second connecting mechanism 3 is used to connect the crossbeam 1 to the vehicle floor (or floor beam), so that the vehicle's A-pillar, front bulkhead, floor, etc., are connected into a whole structure through the steering support beam structure, further improving the overall structural strength of the vehicle and further enhancing the vehicle's safety and reliability. Moreover, the two ends of the second connecting mechanism 3 are detachably connected to the crossbeam 1 and the floor, respectively. On the one hand, this improves the convenience of installation and disassembly between the crossbeam 1, the floor, and the second connecting mechanism 3, and enhances the convenience of assembly and subsequent maintenance of the steering support beam structure. On the other hand, by setting up the steering support beam structure, the crossbeam 1 does not need to be directly connected to the floor. The crossbeam 1 can achieve (indirect) connection to the floor based on a relatively simple structure, thereby avoiding the problems of increased space occupation, manufacturing costs, and difficulty in supporting the crossbeam 1 due to structural complexity. While ensuring the functionality of the steering support beam structure, it reduces the manufacturing difficulty of the steering support beam structure and improves the transportation convenience of the steering support beam structure.
[0049] Optionally, combined Figure 1 and Figure 2 As shown, the crossbeam 1 includes a beam body 11 and an extension beam 12. The two ends of the beam body 11 are detachably connected to two A-columns respectively. The extension beam 12 is mounted on the crossbeam 1 and extends toward the floor. One end of the second connecting mechanism 3 is detachably connected to the end of the extension beam 12 that extends toward the floor.
[0050] In this embodiment, the crossbeam 1 in the steering support beam structure includes a beam body 11 and an extension beam 12. The crossbeam 1 is detachably connected to the A-pillar through the beam body 11, such that both ends of the beam body 11 are detachably connected to the two A-pillars respectively. The extension beam 12 is disposed on the beam body 11, one end of the extension beam 12 is connected to the beam body 11, and the other end extends toward the floor. The end of the extension beam 12 extending toward the floor is detachably connected to the floor through the second connecting mechanism 3. Thus, by setting the extension beam 12, on the one hand, the extension beam 12 serves as a carrier for connecting to the second connecting mechanism 3, facilitating effective connection with the second connecting mechanism 3; on the other hand, compared to the crossbeam 1 with a strip structure, the crossbeam 1 in this embodiment includes a beam body 11 and an extension beam 12 perpendicularly arranged relative to the beam body 11. The setting of the extension beam 12 increases the surface area of the crossbeam 1. Through the cooperation of the beam body 11, the extension beam 12, and the vehicle components, the position of the crossbeam 1 in the vehicle can be stabilized, improving the crossbeam 1's anti-deflection ability, and making the force distribution of the crossbeam 1 more uniform, enhancing the crossbeam 1's anti-bending rigidity, and improving the crossbeam 1's load-bearing capacity against external impacts. In addition, the setting of the extension beam 12 facilitates the reduction of the length (or size) of the second connecting mechanism 3, improving the convenience of installation of the second connecting mechanism 3 (a shorter second connecting mechanism 3 is easier to operate during assembly); and a shorter second connecting mechanism 3 can reduce potential vibration and noise problems, thereby improving the comfort and stability of the vehicle during driving.
[0051] Optionally, combined Figure 1 and Figure 2 As shown, the extension beam 12 includes a connecting beam 123 and a first beam 121 and a second beam 122 spaced apart on the beam body 11. The ends of the first beam 121 and the second beam 122 away from the beam body 11 both extend toward the floor. One end of the connecting beam 123 is connected to the first beam 121, and the other end is connected to the second beam 122. In the extension direction of the first beam 121, the connecting beam 123 is spaced apart from the beam body 11. The ends of the first beam 121 and the second beam 122 that extend toward the floor are detachably connected to the floor through the second connecting mechanism 3.
[0052] In this embodiment, the extension beam 12 of the crossbeam 1 is provided with a first beam 121 and a second beam 122. The ends of the first beam 121 and the second beam 122 extending toward the floor are respectively detachably connected to the floor through a second connecting mechanism 3. This increases the contact area between the crossbeam 1 and the floor (indirectly), thereby improving the stability of the crossbeam 1 when connected to the floor through the second connecting mechanism 3. Furthermore, the first beam 121 and the second beam 122 are spaced apart on the beam body 11. For example, if the first beam 121 and the second beam 122 are spaced apart in the extension direction of the beam body 11, the stress distribution of the crossbeam 1 is more uniform, further improving the bending resistance and overall structural stability of the crossbeam 1. In some embodiments, the vehicle floor is provided with a central channel, which serves as one of the main load-bearing structures in a car collision, and has the function of absorbing collision energy and transmitting collision force. A first beam 121 and a second beam 122 are provided at intervals, and the ends of the first beam 121 and the second beam 122 extending toward the floor are respectively detachably connected to the floor through a second connecting mechanism 3. That is, the second connecting mechanism 3 detachably connected to the first beam 121 and the second connecting mechanism 3 detachably connected to the second beam 122 are also provided at intervals to adapt to the central channel structure (such as both being detachably connected to the floor on both sides of the central channel).
[0053] Furthermore, the extension beam 12 is also provided with a connecting beam 123 for connecting the first beam 121 and the second beam 122 to improve the structural stability of the extension beam 12. In the extension direction of the first beam 121 (or the second beam 122), the connecting beam 123 is spaced apart from the beam body 11, meaning there is a cavity (or hollow structure) between the connecting beam 123 and the beam body 11. Thus, while improving the structural stability of the extension beam 12 by connecting the first beam 121 and the second beam 122 through the connecting beam 123, the extension beam 12 is also lightweight, avoiding unnecessary weight increase. For example, the extension beam 12 has an overall H-shaped structure or a similar H-shaped structure.
[0054] Optionally, combined Figure 1 and Figure 2 As shown, the end of the second connecting mechanism 3 facing the crossbeam 1 overlaps with the end of the extension beam 12 extending towards the floor, and the connection is detachable at the overlap.
[0055] In this embodiment, the end of the second connecting mechanism 3 facing the crossbeam 1 overlaps with the end of the extension beam 12 extending towards the floor, and is detachably connected at the overlap, for example by bolt connection, to increase the contact area when the second connecting mechanism 3 and the extension beam 12 are connected, thereby improving the connection stability when the second connecting mechanism 3 and the extension beam 12 are connected.
[0056] For example, in the extension direction of the extension beam 12 (such as the direction from the beam body 11 to the floor), the second connecting mechanism 3 and the extension beam 12 have an overlapping portion at the connection point, achieving an lap joint. This overlapping portion increases the contact area between the connection surfaces of the second connecting mechanism 3 and the extension beam 12, thereby effectively improving the stability and pull-out resistance of the connection between the second connecting mechanism 3 and the extension beam 12. This allows the second connecting mechanism 3 to not only firmly fix the extension beam 12 but also to evenly distribute the load acting on the connection point, avoiding local stress concentration, and thus enhancing the overall load-bearing capacity and impact resistance of the steering support beam structure. Furthermore, the lap joint design makes the connection tighter, reducing the risk of loosening due to vibration or external impact, and ensuring the safety and reliability of the steering support beam structure in actual use.
[0057] Optionally, the second connecting mechanism 3 is provided with reinforcing ribs to improve its structural strength. For example, the cross-section of the second connecting mechanism 3 is H-shaped or similar.
[0058] Optionally, the second connecting mechanism 3 can be connected to the extension beam 12 using a sheet metal bracket. The sheet metal bracket has the characteristics of high plasticity and low mold cost, which can achieve matching with the needs of different vehicle models. It also facilitates VAVE (Value Analysis and Value Engineering) and design change adjustments in the later stage, improving the flexibility and adaptability of the design.
[0059] Optionally, the corresponding components of the steering support beam structure can be made of plastic-coated steel, in conjunction with the above structure, to ensure the modal performance of the vehicle steering system, reduce the risk of steering wheel vibration, achieve extreme lightweighting of the steering support beam structure, and make the structural form of the steering support beam structure highly diversified, making it easy to avoid surrounding parts and meet assembly requirements.
[0060] Another embodiment of this utility model provides a vehicle including the above-described steering support beam structure.
[0061] In this embodiment, the vehicle employs the aforementioned steering support beam structure. Specifically, the steering support beam structure is detachably connected to the A-pillar and front bulkhead via a crossbeam 1, providing support for the A-pillar and front bulkhead when the crossbeam 1 is connected to them, thus improving the overall structural stability of the vehicle. Furthermore, the detachable connection allows the steering support beam structure to be disassembled into multiple independent components for manufacturing, assembly, transportation, and maintenance, significantly reducing the manufacturing difficulty and improving the transportation convenience of the steering support beam structure. In addition, compared to an integrated structure, the steering support beam structure used in this embodiment adopts a modular design. The components of the steering support beam structure can be flexibly selected and combined according to different vehicle models, avoiding the complexity and high cost of customized production of the steering support beam structure, improving the applicability of each component, and facilitating later adjustments and upgrades.
[0062] Although the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
