Description

Technical Field

[0001] This utility model relates to a vehicle dashboard assembly, specifically to a steering support mounting structure and a vehicle. Background Technology

[0002] In the automotive body structure, the steering support mounting structure plays a crucial role. It is not only the core mounting carrier for key components such as the dashboard, steering column, and various electrical components, but also an important link to ensure a stable connection between these components and the vehicle body. The rationality of its structural design directly affects the assembly precision, functional realization, and overall styling effect of the automotive interior. Currently, see Figure 1 The existing steering support mounting structure shown includes an existing bracket 10 and an existing bracket 20. The existing bracket 20 is welded and fixed to the vehicle body 4. The existing bracket 10 has a Z-shaped structure, with one end directly fixed to the vehicle body 4 and the other end fixedly connected to the vertical mounting part on the existing bracket 20. The existing bracket 10 has mounting through holes adapted to the steering support horizontal tube 3. This structure has played a positive role in specific automotive interior design scenarios, but its inherent structural characteristics also bring obvious limitations. The most prominent problem is the significant limitation on the shape of the dashboard. Due to the compact layout of the end structure of the Z-shaped bracket, it is difficult to achieve a wide-body design in the end area of ​​the dashboard connected to the bracket, and it can only adapt to the narrow-body shape requirements of the dashboard end.

[0003] However, as the automotive consumer market continues to demand more personalized and luxurious interior designs, interior styling is developing towards a more diverse and sophisticated direction, with wide-body end designs on both sides of the dashboard becoming increasingly common. This wide-body design not only provides drivers and passengers with a more spacious operating area and visual enjoyment but also integrates more functional modules. However, the traditional Z-shaped steering support end structure, due to its spatial layout limitations, cannot provide sufficient installation space for this wide-body instrument panel (IP). This makes it difficult for the wide-body instrument panel to effectively match existing steering support structures, severely restricting the innovation and upgrading of interior design.

[0004] Furthermore, regarding the connection structure on the vehicle body side, existing designs typically consist of multiple combined brackets welded together to form the corresponding fixed end structure. This multi-bracket welding method has significant drawbacks: firstly, the welding layers are complex, requiring multiple welding processes to complete the manufacturing of the fixed end, which not only increases the complexity of the production process and manufacturing costs but also reduces production efficiency; secondly, due to the welding assembly of multiple components, the precision control of each welding step faces challenges, easily leading to cumulative errors, making it difficult to guarantee the overall precision of the fixed end. This, in turn, affects the stability and reliability of the connection between the steering support mounting structure and the vehicle body, posing potential risks to the overall performance and safety of the vehicle.

[0005] In summary, the existing automotive steering support mounting structure has significant shortcomings in adapting to new interior styling requirements and ensuring structural precision and reliability, and urgently needs optimization and improvement. Summary of the Invention

[0006] The purpose of this invention is to provide a steering support mounting structure that allows for more adjustment options in dashboard interior design and improves assembly success rate.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: In a first aspect, this utility model discloses a steering support mounting structure, including a first bracket and a second bracket fixedly connected; the first bracket includes a first mounting part and a first mounting groove, and the second bracket includes a second mounting part and a second mounting groove disposed opposite to the first mounting groove; the first mounting groove and the second mounting groove together form an mounting channel adapted to the end of the steering support cross tube; the first mounting part is provided with at least one first mounting hole, and the second mounting part is provided with at least one second mounting hole corresponding to the position of the first mounting hole; the first mounting part and the second mounting part are fixedly connected to the vehicle body.

[0008] Furthermore, the first bracket has a first plug weld hole in the first mounting groove area, and the second bracket has a second plug weld hole in the second mounting groove area; the first bracket and the second bracket are respectively welded and fixed to the end of the steering support cross tube through the first plug weld hole and the second plug weld hole.

[0009] Furthermore, a portion of the edge of the first bracket is provided with a first overlapping edge, and a portion of the edge of the second bracket is provided with a second overlapping edge that is welded and fixed to the first overlapping edge.

[0010] Furthermore, the second bracket also includes a third mounting part that is fixedly connected to the first bracket. The third mounting part is provided with a third plug welding hole, through which the second bracket and the first bracket are welded and fixed.

[0011] Furthermore, the first bracket and the second bracket are respectively provided with a first positioning hole and a second positioning hole for the positioning pin to pass through. The side of the vehicle body away from the first bracket is fixedly connected to the limiting bracket. The limiting bracket is provided with a limiting part to prevent the positioning pin from tilting upward.

[0012] Furthermore, the positioning pin includes a head and a rod, the outer diameter of the head being larger than the outer diameter of the rod; the head is welded and fixed to the side of the bracket two opposite to the bracket one.

[0013] Furthermore, the rod is provided with an anti-reverse groove.

[0014] Furthermore, the first mounting holes of the first mounting part are arranged at intervals along the vertical direction; the second bracket is C-shaped, and the two free ends of the second bracket are the second mounting parts, and the second mounting holes on the second mounting parts correspond to the positions of the first mounting holes on the upper and lower ends of the first mounting part.

[0015] Furthermore, a projection weld nut is fixed at the position corresponding to the first mounting hole of the bracket, and the projection weld nut is fixed on the side of the vehicle body away from the bracket.

[0016] Secondly, this utility model discloses a vehicle, including a steering support assembly, wherein the steering support assembly includes the aforementioned steering support mounting structure.

[0017] This utility model has the following unexpected beneficial effects: 1. The first mounting part of this utility model is provided with at least one first mounting hole, and the second mounting part is provided with at least one second mounting hole corresponding to the position of the first mounting hole. The first mounting part and the second mounting part are fixedly connected to the vehicle body, that is, all mounting points of the bracket are directly provided by the vehicle body, without the need to set up other brackets to provide mounting points. This configuration further simplifies the overall structure, reduces the space occupied by redundant parts, and thus better meets the styling requirements of automotive interiors. Whether in a compact space or a complex styling layout, it can leave more room for adjustment in interior design, making the realization of styling solutions more flexible and smooth.

[0018] 2. This utility model forms an installation channel that fits the end of the steering support cross tube by means of the first mounting groove and the second mounting groove. This allows for a more precise fit to the structural characteristics of the steering support cross tube, significantly improving the compatibility of the assembly with the steering support cross tube. Furthermore, the cooperation between the first mounting groove and the second mounting groove can effectively accommodate dimensional errors within a certain range, avoiding assembly failures caused by minor dimensional deviations during component processing or assembly. This improves the success rate and efficiency of assembly, while also enhancing the reliability of the structural connection. Attached Figure Description

Detailed Implementation

[0029] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0030] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0031] In one embodiment, see Figures 2 to 5 As shown, this utility model discloses a steering support mounting structure, including a first bracket 1 and a second bracket 2 fixedly connected. The first bracket 1 includes a first mounting portion 11 and a first mounting groove 12. The second bracket 2 includes a second mounting portion 21 and a second mounting groove 22 opposite to the first mounting groove 12. The first mounting groove 12 and the second mounting groove 22 together form a mounting channel adapted to the end of the steering support cross tube 3. The first mounting portion 11 has at least one first mounting hole 13, and the second mounting portion 21 has at least one second mounting hole 23 corresponding to the position of the first mounting hole 13. The first mounting portion 11 and the second mounting portion 21 are fixedly connected to the vehicle body 4.

[0032] Since the first mounting part 11 has at least one first mounting hole 13, and the second mounting part 21 has at least one second mounting hole 23 corresponding to the position of the first mounting hole 13, the first mounting part 11 and the second mounting part 21 are fixedly connected to the vehicle body 4. This means that all mounting points for the bracket are directly provided by the vehicle body 4, eliminating the need for additional brackets. This design further simplifies the overall structure, reduces the space occupied by unnecessary components, and thus better meets the styling requirements of automotive interiors. Whether in a compact space or a complex layout, it allows for more flexibility in interior design adjustments, making the implementation of styling solutions more flexible and smooth.

[0033] Furthermore, this invention forms an installation channel that fits the end of the steering support cross tube 3 by means of the first mounting groove 12 and the second mounting groove 22. This allows for a more precise fit to the structural characteristics of the steering support cross tube 3, significantly improving the compatibility of the assembly with the steering support cross tube 3. Moreover, the cooperation between the first mounting groove 12 and the second mounting groove 22 can effectively accommodate dimensional errors within a certain range, avoiding assembly failures caused by minor dimensional deviations during component processing or assembly. This improves the success rate and efficiency of assembly, while also enhancing the reliability of the structural connection.

[0034] And see also Figure 3 As shown, bracket 1 and bracket 2 are fixedly connected to form an integral structure. Compared with traditional single Z-shaped brackets or multi-bracket welded structures, this combination can distribute the load through a reasonable force transmission path, significantly improving the rigidity and stability of the overall structure. It can effectively bear the weight of components such as the dashboard, steering column, and various electrical components, as well as the vibrations and impacts generated during vehicle operation, providing a solid structural foundation for the stable installation of related components. Simultaneously, in terms of meeting overall vehicle performance requirements, this structure can meet the vehicle's modal requirements, ensuring that the vibration characteristics of the steering support mounting structure are coordinated with other vehicle components during vehicle operation, avoiding resonance. This helps improve the vehicle's ride smoothness, comfort, and NVH (noise, vibration, and harshness) performance, ensuring the overall performance of the vehicle.

[0035] In terms of adapting to interior styling, this structure breaks through the limitations of traditional Z-shaped brackets on dashboard shapes. Through the ingenious design of bracket 1 and bracket 2, especially the layout of the first mounting part 11 and the second mounting part 21, it can provide ample installation space for the wide-body end shapes on both sides of the dashboard, well meeting the offset styling requirements of the dashboard, conforming to the current trend of personalized and luxurious automotive interiors, and providing greater freedom for interior design innovation.

[0036] In terms of installation and connection, the first mounting hole 13 provided on the first mounting part 11 and the second mounting hole 23 provided on the second mounting part 21 provide a convenient and reliable interface for fixed connection with the vehicle body 4. This not only simplifies the installation process and reduces the assembly difficulty, but also helps to ensure the accuracy and stability of the connection, reduces structural errors and performance risks caused by improper installation, and also simplifies the production process to a certain extent, which helps to improve production efficiency.

[0037] As a preferred embodiment of this utility model, see [link to relevant documentation]. Figure 4 As shown, the bracket 1 has a first plug weld hole 14 in the area of ​​the first mounting groove 12. (See also...) Figure 5As shown, the bracket 2 has a second plug weld hole 24 in the area of ​​the second mounting groove 22. (See also...) Figure 3 As shown, bracket 1 and bracket 2 are respectively welded to the ends of the steering support cross tube 3 through the first plug welding hole 14 and the second plug welding hole 24.

[0038] In this preferred embodiment, the first plug weld hole 14 of bracket 1 and the second plug weld hole 24 of bracket 2 correspond to the welding positions at the ends of the steering support cross tube 3, respectively. The plug welding process enables the weld to form a tight bond with the connecting surface, achieving a high-strength fixed connection between bracket 1, bracket 2, and the steering support cross tube 3. Compared with ordinary lap welding, this effectively avoids problems such as loosening and displacement caused by insufficient connection strength, ensuring that the three components maintain a stable overall structure under the vibration and impact environment of long-term vehicle operation, providing continuous and reliable support for the installation of related components. Secondly, the stress distribution of the structure is optimized. The plug weld holes are located in the areas of the first mounting groove 12 and the second mounting groove 22. The first mounting groove 12 and the second mounting groove 22 together form a mounting channel that fits the end of the steering support cross tube 3, meaning the welding point is located at a critical stress-bearing part of the structure. When the steering support cross tube 3 bears the load of components such as the instrument panel and steering column, the connection point formed by the plug weld can evenly transmit the force to bracket 1 and bracket 2, and then distribute it to the vehicle body through the mounting part connected to the vehicle body 4, reducing local stress concentration and further improving the load-bearing capacity and fatigue resistance of the entire steering support mounting structure.

[0039] Finally, the accuracy and convenience of assembly are improved. The compatibility between the first mounting groove 12 and the second mounting groove 22 and the end of the steering support cross tube 3 provides a good positioning reference for the welding process, while the setting of the plug welding hole clearly defines the welding position, making it easier for operators to weld accurately and reducing assembly errors caused by welding position deviations. At the same time, the plug welding process is relatively simple to operate, which helps to improve the assembly efficiency on the production line, and the weld quality is easier to control, reducing rework costs caused by welding defects, thus ensuring the consistency and stability of the product from a process perspective.

[0040] As a preferred embodiment of this utility model, see [link to relevant documentation]. Figures 3 to 5 As shown, a portion of the edge of the bracket 1 is provided with a first overlapping edge 15, and a portion of the edge of the bracket 2 is provided with a second overlapping edge 25 that is welded and fixed to the first overlapping edge 15.

[0041] In this preferred embodiment, the bracket 1 and bracket 2, after being welded together at their overlapping edges, form a more enclosed combined structure, significantly reducing the probability of deformation that may occur in a single bracket due to its own structural characteristics. This integrated structure can more evenly bear the load from components such as the steering support cross tube 3 and the instrument panel, reducing local deformation of the structure under stress, thereby enhancing the overall rigidity of the entire steering support installation structure and providing a more solid guarantee for the stable installation of related components. Furthermore, it helps ensure the accuracy and consistency of the assembly process; the setting of the first overlapping edge 15 and the second overlapping edge 25 provides a clear positioning benchmark for the assembly of bracket 1 and bracket 2, enabling rapid and precise alignment before welding and reducing positional deviations during assembly. At the same time, the welding operation of the overlapping edges is simple and intuitive, facilitating rapid operation by workers on the production line, improving assembly efficiency, and ensuring consistency between different products through standardized overlapping dimensions and welding processes, reducing quality fluctuations caused by assembly errors.

[0042] For example, the first overlapping edge 15 is formed on the side edge of the bracket 1 away from the vehicle body 4, and the second overlapping edge 25 is formed on the side edge of the bracket 2 away from the vehicle body 4.

[0043] As a preferred embodiment of this utility model, see [link to relevant documentation]. Figure 5 As shown, the bracket 2 further includes a third mounting part 26 that is fixedly connected to the bracket 1. The third mounting part 26 is provided with a third plug welding hole 27, through which the bracket 2 and the bracket 1 are welded and fixed.

[0044] Based on the lap welding, the addition of a new connection point at the third mounting section 26 creates a multi-dimensional stress system between the two supports. The welding process of the third plug weld hole 27 enables a high-strength joint to be formed at this location, effectively dispersing the forces between the supports and preventing loosening or damage to a single connection point due to long-term stress concentration. This significantly improves the fatigue resistance and durability of the overall connection structure, ensuring that support one and support two always maintain a stable assembly state.

[0045] Furthermore, the position design of the third mounting part 26 can be rationally arranged according to the structural stress requirements, making the force transmission path between bracket 1 and bracket 2 more optimized. When the steering support mounting structure bears loads from components such as the steering support cross tube and instrument panel, the third mounting part 26 can share some of the force, reducing the stress on other connecting parts, thereby making the stress on the entire structure more uniform, further improving the overall load-bearing capacity and structural rigidity, and providing more reliable support for the stable installation of related components. For example, the third mounting part 26 is formed on the lower edge of the bracket 2 near the vehicle body 4.

[0046] Meanwhile, the third mounting part 26 provides an additional positioning reference for the assembly of bracket 1 and bracket 2, assisting in achieving more precise alignment during welding and reducing assembly deviations. Furthermore, the welding operation of the third plug weld hole 27 is simple and controllable, allowing operators to adjust the welding sequence according to actual conditions and improving assembly efficiency. In addition, the extra connection point enhances the structure's fault tolerance; even if minor errors exist in other connection parts, the connection of the third mounting part 26 can compensate for them to a certain extent, ensuring the overall assembly quality of the structure.

[0047] As a preferred embodiment of this utility model, see [link to relevant documentation]. Figure 2 , Figures 4 to 8 As shown, bracket 1 and bracket 2 are respectively provided with a first positioning hole 16 and a second positioning hole 28 for the positioning pin 5 to pass through. The vehicle body 4 is provided with a third positioning hole 42 for the positioning pin 5 to pass through. The side of the vehicle body 4 away from bracket 1 is fixedly connected to the limiting bracket 6. The limiting bracket 6 is provided with a limiting part 61 to prevent the positioning pin 5 from tilting upward.

[0048] The first positioning hole 16 of bracket 1, the second positioning hole 28 of bracket 2, and the third positioning hole 42 of vehicle body 4 are connected by positioning pins 5, forming a clear and rigid positioning reference. This ensures the accurate relative position between bracket 1, bracket 2, and vehicle body 4 from the initial stage of assembly. This multi-component collaborative positioning method effectively avoids the cumulative errors that may occur in traditional assembly, providing a precise positional basis for subsequent fixed connections (such as welding, bolting, etc.), and ensuring that the connection between the entire steering support installation structure and the vehicle body meets the design dimensional requirements.

[0049] Furthermore, after the positioning pin 4 passes through each positioning hole, it can limit the relative displacement between bracket 1, bracket 2 and vehicle body 4 to a certain extent. Especially when subjected to dynamic loads such as vibration and impact, it can reduce the shaking caused by loosening between components. The limiting bracket 6 fixed on the side of vehicle body 4 away from the bracket has a limiting part 61 that can effectively prevent the positioning pin 5 from tilting upwards, further locking the position of the positioning pin 5 and preventing the positioning pin from tilting upwards under force, which would affect assembly.

[0050] As a preferred embodiment of this utility model, see [link to relevant documentation]. Figure 6 As shown, the positioning pin 5 includes a head 51 and a rod 52, the outer diameter of the head 51 is larger than the outer diameter of the rod 52; the head 51 is welded and fixed to the side of the bracket 2 away from the bracket 1.

[0051] In this preferred embodiment, the positioning pin 5 adopts a stepped structure of head 51 and rod 52, with the outer diameter of head 51 being larger than that of rod 52, allowing head 51 to reliably fit and support the side of bracket 2 away from bracket 1. Furthermore, welding head 51 to bracket 2 further securely connects positioning pin 5 and bracket 2 into a single unit, preventing axial movement or loosening of positioning pin 5 during assembly or use, thus fundamentally ensuring the stability of positioning pin 5 as a positioning reference.

[0052] Furthermore, the welding and fixing of the head 51 to the bracket 2 ensures that the position of the positioning pin 5 is precisely locked on the bracket 2. The rod 52, after passing through the first positioning hole 16 on the bracket 1 and the second positioning hole 41 on the vehicle body 4, can reliably guarantee the relative positional accuracy between the bracket 1, bracket 2, and the vehicle body 4 through this rigid fixing relationship. Compared to the positioning method that relies solely on the cooperation between the positioning hole and the rod 52, this structure with the welded head 51 reduces the impact of the positioning pin 5's own positional deviation on the overall positioning, further reducing assembly errors and providing a more precise foundation for the subsequent connection of various components.

[0053] As a preferred embodiment of this utility model, see [link to relevant documentation]. Figure 6 As shown, the rod 52 is provided with a backstop groove 53.

[0054] The anti-reverse groove 53 provides an additional axial limiting structure for the positioning pin 5. After the positioning pin 5 passes through the positioning holes of bracket 1, bracket 2, and vehicle body 4, the anti-reverse groove 53 can cooperate with the third positioning hole 42 on the vehicle body 4 to restrict the movement of the positioning pin 5 in the axial direction. Even if the vehicle is subjected to severe vibration or impact during driving, it can prevent the positioning pin 5 from accidentally coming out of the positioning hole, ensuring that the positioning pin 5 always remains in the preset positioning position, and providing continuous protection for the relative positional accuracy of each component.

[0055] As a preferred embodiment of this utility model, see [link to relevant documentation]. Figure 4 and Figure 5 As shown, the first mounting part 11 has a plurality of first mounting holes 13 arranged at intervals in the vertical direction; the bracket 2 is C-shaped, and the two free ends of the bracket 2 are the second mounting part 21, and the second mounting holes 23 on the second mounting part 21 correspond to the positions of the first mounting holes 13 on the upper and lower ends of the first mounting part 11.

[0056] In this preferred embodiment, the plurality of first mounting holes 13 of the first mounting part 11 are arranged at intervals in the vertical direction. This longitudinal distribution design allows the connection point between the bracket 1 and the vehicle body 4 to form a more balanced force support in the vertical direction. When the steering support mounting structure bears loads from above or below, the vertically spaced first mounting holes 13 can transmit the force more evenly to the vehicle body 4, reducing the stress on individual connection points and lowering the risk of loosening or damage due to local overload. At the same time, the bracket 2 is C-shaped, with its two free ends serving as the second mounting part 21, and the second mounting holes 23 correspond to the positions of the first mounting holes 13 at the upper and lower ends of the first mounting part 11. This allows the connection point between the bracket 2 and the vehicle body 4 to form a cooperative force-bearing structure with the connection point of the bracket 1, further improving the stability of the overall structure and the connection with the vehicle body, and jointly bearing the weight of the steering support cross tube and related components. The C-shaped bracket 2 has a certain degree of elasticity and tolerance, which can better accommodate minor dimensional deviations during assembly, while providing ample space for the installation of the steering support cross tube 3 and surrounding components. The corresponding design of the second mounting hole 23 with the first mounting holes 13 at the upper and lower ends of the first mounting part 11 ensures that bracket 1 and bracket 2 maintain a precise relative position when connected to the vehicle body 4, avoiding structural distortion or stress concentration caused by misalignment of the connection points. This correspondence also simplifies the positioning process during assembly; operators can quickly complete the initial fixation of the bracket to the vehicle body by aligning the holes, improving the convenience and accuracy of assembly.

[0057] The first mounting holes 13 are spaced apart vertically, avoiding excessive space occupation in the horizontal direction and leaving more room for the installation of components such as the dashboard, which conforms to the design trend of compact and integrated automotive interiors. The C-shaped bracket structure reduces unnecessary material consumption while ensuring strength, which helps to achieve structural lightweighting.

[0058] For example, there are four first mounting holes 13, which are arranged vertically at intervals along the edge of the bracket 1 near the vehicle body 4. There are two second mounting holes 23, which correspond to the positions of the uppermost and lowermost first mounting holes 13 of the bracket 1, respectively.

[0059] As a preferred embodiment of this utility model, see [link to relevant documentation]. Figure 7 and Figure 8 As shown, a projection-welded nut 7 is fixed at the position corresponding to the first mounting hole 13 of the bracket 1 on the vehicle body 4. The projection-welded nut 7 is fixed on the side of the vehicle body 4 away from the bracket 1. That is, a through hole 41 is provided at the position corresponding to the first mounting hole 13 of the bracket 1 on the vehicle body 4, and a projection-welded nut is welded and fixed on the side of the through hole 41 away from the bracket 1.

[0060] In this preferred embodiment, the projection weld nut 7 is fixed to the side of the vehicle body 4 away from the bracket 1 via the through hole 41 by welding. This ensures that the projection weld nut 7 and the vehicle body 4 form a high-strength integral structure, avoiding the connection failure problem caused by nut loosening in traditional bolt connections. When the bolt passes through the first mounting hole 13 of the bracket 1 and the through hole 41 of the vehicle body 4 and engages with the projection weld nut 7, a stable threaded connection can be formed, which can effectively withstand the load transmitted by the steering support mounting structure. Even in the vibration environment of long-term vehicle operation, the connection can remain tight, providing a solid guarantee for the fixation of the bracket 1 and the vehicle body.

[0061] Furthermore, since the projection weld nut 7 is pre-fixed to the vehicle body 4 and precisely corresponds to the first mounting hole 13 of the bracket 1, there is no need to separately position and fix the nut during assembly. The operator only needs to pass the bolt directly through the relevant hole and tighten it with the projection weld nut 7, which greatly simplifies the assembly process. This pre-assembly design reduces the adjustment time of the nut during assembly, reduces assembly difficulties caused by nut position deviation, helps improve the assembly efficiency of the production line, and also ensures the consistency of assembly of different products. Meanwhile, since the projection weld nut 7 is located on the side of the vehicle body 4 away from the bracket 1, the projection weld nut 7 avoids occupying the installation space between the bracket 1 and the vehicle body 4, providing greater flexibility for the structural design of the bracket 1, and will not cause spatial interference to the installation of components such as the instrument panel.

[0062] For example, the vehicle body 4 is the inner panel of the A-pillar.

[0063] In one embodiment, the present invention discloses a vehicle including a steering support assembly, the steering support assembly including the steering support mounting structure described above.

[0064] It should be noted that the vehicles mentioned can be, but are not limited to, pure electric vehicles (PEV / BEV), hybrid electric vehicles (HEV), range-extended electric vehicles (REEV), plug-in hybrid electric vehicles (PHEV), new energy vehicles, and gasoline vehicles.

[0065] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
