Description

Technical Field

[0001] This application relates to the field of vehicle equipment technology, and in particular to a steering support cross tube and a vehicle. Background Technology

[0002] As the core support framework of the dashboard assembly, the automotive steering support assembly needs to simultaneously support the installation requirements of multiple key components such as the steering column, air conditioning system, and airbags. The steering support transverse tube structure, as the main tube beam structure of the steering support assembly, can connect the left and right sides of the vehicle and can be used to install or clamp the steering column, air conditioning system, and airbag structure.

[0003] However, the steering support cross tube in the aforementioned technologies has poor compatibility and may block the air conditioning vents. Utility Model Content

[0004] In view of this, this application provides a steering support cross tube and a vehicle to solve the technical problem in the above-mentioned related technologies that the steering support cross tube has poor compatibility and will block the air outlet of the air conditioner.

[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0006] A first aspect of this application provides a steering support cross tube, including a first cross tube, a second cross tube, and a third cross tube arranged and connected to each other along a first direction;

[0007] The second horizontal tube is located between the first horizontal tube and the third horizontal tube;

[0008] Along the second direction, the second horizontal tube is arranged at intervals from the first horizontal tube, and the second direction is perpendicular to the first direction;

[0009] Along the first direction, the first horizontal tube and the third horizontal tube are in the same straight line;

[0010] The first horizontal pipe, the second horizontal pipe, and the third horizontal pipe together form a clearance zone, which is used to avoid the air outlet of the air conditioner.

[0011] This application provides a steering support cross tube. A first and third cross tube are arranged in a straight line along the vehicle's transverse direction, forming a basic support frame. A second cross tube is offset relative to the first cross tube in the vehicle's longitudinal direction by a predetermined amount. This offset is dynamically adjusted according to the actual installation position of the air conditioning vent. The three cross tubes are connected by welding or bolts to form a stable support structure. The longitudinal offset of the second cross tube avoids the air conditioning vent. During final assembly, by changing the installation angle and offset of the second cross tube, the avoidance area can precisely correspond to the air conditioning vent position of different vehicle models. This maintains the integrity of the tube body and allows for adaptation to different vehicle model requirements by adjusting the component position, thus improving the compatibility of the steering support cross tube.

[0012] In addition, the three-tube split design maintains the overall structural strength while enabling the adjustability of key areas, avoiding the problem of localized strength weakening caused by opening gaps.

[0025] The third horizontal tube includes a fifth end and a sixth end opposite to each other along the first direction, and the fifth end is connected to the fourth end.

[0026] In some embodiments of this application, the second connection structure includes:

[0027] The base plate has a recess and an opening;

[0028] A snap-on plate is snapped onto the opening and connected to the base plate. The snap-on plate, the recess, and the base plate together form a box-like structure with an internal cavity.

[0056] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0057] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0058] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0059] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0060] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0061] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0062] The aforementioned steering support cross tubes have poor compatibility and can obstruct air conditioning vents. This problem arises because existing automotive steering support cross tubes often employ a single, straight structure or a simple segmented design. These structures have significant limitations when dealing with four-zone climate control systems and large airbag modules. Traditional single-tube or dual-tube combinations, limited by fixed connections, cannot effectively adjust the relative positions of functional areas. This results in the air conditioning vent area not being aligned with the steering column mounting position or the airbag placement space. When these structures are installed on the steering support cross tube, the air conditioning vents interfere with the tube, obstructing the vents and affecting airflow. Especially when the air conditioning system requires larger vents, conventional steering support cross tubes often obstruct the upper edge of the vents, affecting the uniformity of airflow distribution.

[0063] Furthermore, when interference occurs, the existing technology uses a method of creating a notch in the steering support cross tube to avoid the interference, which damages the overall structure of the steering support cross tube and leads to a loss of structural strength of the steering support cross tube.

[0064] To address the aforementioned issues, this application provides a steering support cross tube and a vehicle. The first and third cross tubes are arranged in a straight line along the vehicle's transverse direction, forming a basic support frame. The second cross tube is offset relative to the first cross tube in the vehicle's longitudinal direction by a predetermined amount, which is dynamically adjusted according to the actual installation position of the air conditioning vents. The three cross tubes are connected by welding or bolts to form a stable support structure, wherein the longitudinal offset of the second cross tube avoids the air conditioning vents. During final assembly, by changing the installation angle and offset of the second cross tube, the avoidance area can precisely correspond to the air conditioning vent positions of different vehicle models, maintaining the integrity of the tube body while adapting to the needs of different vehicle models by adjusting the component positions, thus improving the compatibility of the steering support cross tube.

[0065] In addition, the three-tube split design maintains the overall structural strength while enabling the adjustability of key areas, avoiding the problem of localized strength weakening caused by opening gaps.

[0066] The steering support cross tube and vehicle provided in this application are described below with reference to the accompanying drawings and specific embodiments.

[0067] Reference Figure 1 and Figure 2 This application provides a steering support cross tube 40, which can move along a first direction (e.g., Figure 1Extending in the X direction, the steering support transverse tube 40 may include a first transverse tube 100, a second transverse tube 200, and a third transverse tube 300 arranged and connected to each other along the first direction. Here, the first direction refers to the direction of the vehicle's lateral axis, such as the width direction of the vehicle body, and is used to determine the extension reference of the steering support transverse tube 40.

[0068] The second horizontal tube 200 is located between the first horizontal tube 100 and the third horizontal tube 300. Along the second direction (e.g.) Figure 1 In the Y direction, the second horizontal tube 200 and the first horizontal tube 100 are arranged at intervals, and the second direction is perpendicular to the first direction. Along the first direction, the first horizontal tube 100 and the third horizontal tube 300 are on the same straight line.

[0069] The second direction refers to the longitudinal axis direction of the vehicle, such as the length direction of the vehicle body, and is used to establish the vertical spacing between the transverse tubes.

[0070] The first horizontal pipe 100, the second horizontal pipe 200 and the third horizontal pipe 300 together form a clearance zone 230, which is used to avoid the air outlet 21 of the air conditioner 20.

[0071] The avoidance zone 230 refers to the recessed area formed by the spatial arrangement of three horizontal pipes. Specifically, it can be achieved by adjusting the offset of the second horizontal pipe 200 in the second direction. This structural feature directly corresponds to the installation position of the air outlet 21 of the air conditioner 20.

[0072] In some embodiments, the first horizontal tube 100 can be used to correspond to and install the airbag 10 on the vehicle body, and the third horizontal tube 300 is used to correspond to and install the steering column 30.

[0073] In practical implementation, the first horizontal tube 100 and the third horizontal tube 300 are aligned in a straight line along the vehicle's transverse direction, forming a basic support frame. The second horizontal tube 200 has a preset offset relative to the first horizontal tube 100 in the vehicle's longitudinal direction. This offset is dynamically adjusted according to the actual installation position of the air conditioning vent 21. The three horizontal tubes are connected by welding or bolts to form a stable support structure. The longitudinal offset of the second horizontal tube 200 creates a bending area at the connection point of the three tubes. The spatial dimension of this bending area is larger than the maximum outer dimension of the air conditioning vent 21. During final assembly, by changing the installation angle and offset of the second horizontal tube 200, the clearance area 230 can be precisely aligned with the position of the air conditioning vent 21 of different vehicle models.

[0074] Compared to existing technologies, traditional integral horizontal tubes require openings in the tube body to avoid obstructions or may block the air outlet 21, resulting in reduced local strength and inability to adapt to multiple configuration requirements. This solution achieves the avoidance function through a split structure, maintaining the integrity of the tube body while allowing for adjustments to the position of the second horizontal tube 200 to accommodate different vehicle models.

[0075] Through the above technical solution, this application effectively solves the technical problem of interference between the air outlet 21 of the air conditioner 20 and the steering support horizontal tube 40, enabling the steering support horizontal tube 40 to adapt to the installation requirements of the air conditioner 20 system in different vehicle configurations. The three-tube split design maintains the overall structural strength while achieving adjustability in key areas, avoiding the problem of local strength weakening caused by opening gaps.

[0076] Reference Figure 2 and Figure 3 In some embodiments, the steering support cross tube 40 may also include a first connecting structure 400.

[0077] The first connecting structure 400 refers to the mechanical component used to connect the first horizontal tube 100 and the second horizontal tube 200. Specifically, it can be achieved by welding or bolting. By adjusting the installation position of the first connecting structure 400, the first horizontal tube 100 and the second horizontal tube 200 can be in a state of adjustable relative position before welding.

[0078] The first horizontal tube 100 may include a first end 110 and a second end 120 disposed opposite to each other along a first direction, the second end 120 being connected to one end of the first connecting structure 400 along a second direction.

[0079] The first direction refers to the length extension direction of the horizontal tube, which can be the vehicle width direction. This direction is used to define the layout reference of the horizontal tubes. The second direction refers to the vertical direction perpendicular to the first direction, which can be the vehicle length direction. This direction is used to define the spacing relationship between the first horizontal tube 100 and the second horizontal tube 200.

[0080] The second horizontal tube 200 may include a third end 210 and a fourth end 220 disposed opposite to each other along a first direction. The third end 210 is connected to one end of the first connecting structure 400 that is opposite to the first horizontal tube 100 along a second direction.

[0081] Specifically, the second end 120 of the first horizontal tube 100 is connected to the third end 210 of the second horizontal tube 200 via the first connecting structure 400 in an adjustable manner. During assembly, the first connecting structure 400 is configured to allow the first horizontal tube 100 and the second horizontal tube 200 to be adjusted in position along a second direction, for example, by changing the distance or angle between them through sliding or rotation. After adjustment, the first horizontal tube 100 and the second horizontal tube 200 are fixed to the first connecting structure 400 by welding or bolting. At this time, the shape and position of the clearance area 230 are determined, thereby adapting to the actual installation requirements of the air outlet 21 of the air conditioner 20.

[0082] This solution introduces a first connecting structure 400, which enables the first horizontal tube 100 and the second horizontal tube 200 to have adjustable positions before welding. This allows the position of the clearance area 230 to be optimized according to actual needs during the assembly stage, achieving flexible adjustment of the clearance area 230's position. At the same time, it simplifies the assembly positioning process before welding and improves the adaptability of the steering support horizontal tube 40 to different vehicle models and air conditioning 20 configurations.

[0083] Reference Figure 2 and Figure 3 In some embodiments, the first connection structure 400 may include a connection plate 410 and a flange structure 430.

[0084] The connecting plate 410 has a first through hole 420 and a second through hole arranged at intervals along the second direction. The second end 120 passes through the first through hole 420 and the third end 210 passes through the second through hole.

[0085] The connecting plate 410 is a flat plate component used to fix the first horizontal tube 100 and the second horizontal tube 200. It can be made of stamped metal plate, and its surface has through holes for positioning and installation of the ends of the horizontal tubes. The first through hole 420 and the second through hole are circular or rectangular holes distributed at intervals along the second direction. They can be formed by drilling or stamping processes and are used to constrain the relative positions of the first horizontal tube 100 and the second horizontal tube 200.

[0086] A flange structure 430 is provided around the outer periphery of the connecting plate 410. The flange structure 430 refers to a flange formed by bending perpendicularly along the edge of the connecting plate 410, which can be achieved through a bending process, and is used to increase the bending stiffness of the edge of the connecting plate 410.

[0087] Specifically, the second end 120 of the first horizontal tube 100 is inserted into the first through hole 420, and the third end 210 of the second horizontal tube 200 is inserted into the second through hole. The through holes constrain the position of the ends of the horizontal tubes, achieving pre-positioning of the two horizontal tubes before welding. The flange structure 430 forms a continuous or intermittent reinforcing edge around the outer edge of the connecting plate 410. When the connecting plate 410 is subjected to external force, the flange disperses stress, preventing local deformation of the connecting plate 410. The combination of the connecting plate 410 and the flange structure 430 ensures both adjustable horizontal tube position and improves the overall stability of the connection area.

[0088] By using through-hole positioning and flange reinforcement, the horizontal pipe position can be flexibly adapted to the air outlet 21 of the air conditioner 20, while structural optimization improves connection reliability. This application solves the problems of low positioning accuracy and poor deformation resistance between the first horizontal pipe 100, the second horizontal pipe 200 and the first connecting structure 400, achieving a synergistic effect of adjustable position of the first horizontal pipe 100 and the second horizontal pipe 200 and improved connection strength. This ensures that the avoidance area 230 can adapt to different air outlet 21 layouts of the air conditioner 20, while preventing the connection area of ​​the first horizontal pipe 100 and the second horizontal pipe 200 from failing due to vibration or load.

[0089] Reference Figure 2 and Figure 3 In some embodiments, the steering support cross tube 40 may further include a first reinforcing plate 500. One end of the first reinforcing plate 500 along a second direction is connected to the first connecting structure 400, and the other end extends obliquely away from the first connecting structure 400 along a first direction and is connected to the first cross tube 100.

[0090] The first reinforcing plate 500 refers to a plate-shaped component connecting the first connecting structure 400 and the first horizontal tube 100. Specifically, it can be formed by stamping steel plates, and its inclination angle can be any angle within the range of 30° or greater and 60° or less. The first reinforcing plate 500 can be fixedly connected to the first connecting structure 400 and the first horizontal tube 100 by welding or bolting. The first reinforcing plate 500 can extend at an incline to form a triangular support structure, which can disperse stress concentration at the connection point between the first horizontal tube 100 and the first connecting structure 400.

[0091] In some embodiments, the first connecting structure 400 serves as an intermediate connector, for example, a connecting plate 410 with a flanged structure 430 can be used to achieve an adjustable connection between the first horizontal tube 100 and the second horizontal tube 200. In this case, one end of the first reinforcing plate 500 is connected to the first horizontal tube 100, and the other end is connected to the connecting plate 410 on the first connecting structure 400.

[0092] In practice, one end of the first reinforcing plate 500 is fixed to the connecting plate 410 of the first connecting structure 400 by welding, and the other end extends at an inclined angle to the side wall of the first horizontal tube 100 for welding and fixing. This inclined layout forms a stable triangular geometric structure between the first reinforcing plate 500, the first connecting structure 400 and the first horizontal tube 100, which can effectively suppress vibration deformation of the connection parts during vehicle operation.

[0093] In this way, by adding an inclined and extended first reinforcing plate 500, a triangular stable structure is constructed, which significantly improves the bending stiffness and fatigue resistance of the connection part, and effectively enhances the connection stability between the first horizontal tube 100 and the second horizontal tube 200. Before welding and assembly, the spatial position of the avoidance zone 230 can be precisely controlled by adjusting the inclination angle and installation position of the first reinforcing plate 500, avoiding the problem of air conditioning vent 21 being blocked due to deformation of the first connecting structure 400. The triangular support structure can also absorb some of the impact energy during a vehicle collision, preventing the steering support horizontal tube 40 from undergoing overall collapse and deformation.

[0094] Reference Figure 2 and Figure 3 In some embodiments, the steering support transverse may further include a first support plate 600a and a second support plate 600b.

[0095] The first support plate 600a is disposed on the first connecting structure 400, and one end is connected to the first reinforcing plate 500, and the other end is connected to the first horizontal tube 100.

[0096] The first support plate 600a refers to the plate-shaped component that connects the first reinforcing plate 500 and the first horizontal tube 100. Specifically, it can be made of metal stamping and fixed to the first connecting structure 400 by welding or bolting. It is used to disperse the stress between the first reinforcing plate 500 and the first horizontal tube 100.

[0097] The second support plate 600b is disposed on the first connecting structure 400, with one end connected to the side of the first reinforcing plate 500 facing away from the first support plate 600a, and the other end connected to the first horizontal tube 100.

[0098] The second support plate 600b refers to a plate-shaped component symmetrically arranged with the first support plate 600a. Specifically, it can be made of the same material and process as the first support plate 600a. It forms a bidirectional support by connecting the other side of the first reinforcing plate 500 to the first horizontal tube 100.

[0099] In some embodiments, the first connecting structure 400 refers to a component for connecting the first horizontal tube 100 and the second horizontal tube 200. Specifically, it can be implemented by combining a connecting plate 410 with a through hole and a flange structure 430, used to position and fix the relative positions of the first horizontal tube 100 and the second horizontal tube 200. The first reinforcing plate 500 refers to an inclined extending reinforcing component, specifically formed by bending a steel plate, which forms a triangular support structure by connecting the first connecting structure 400 and the first horizontal tube 100.

[0100] In practical implementation, the first support plate 600a and the second support plate 600b are located on both sides of the first reinforcing plate 500 and connected to the first horizontal tube 100. One end of the first support plate 600a is welded to the side of the first reinforcing plate 500, and the other end is welded to the side wall of the first horizontal tube 100. One end of the second support plate 600b is welded to the other side of the first reinforcing plate 500, and the other end is also welded to the side wall of the first horizontal tube 100. The connecting plate 410 of the first connecting structure 400 is sleeved on the second end 120 of the first horizontal tube 100 and the third end 210 of the second horizontal tube 200 through the first through hole 420 and the second through hole, respectively. The flange structure 430 is formed by bending along the edge of the connecting plate 410 to increase the deformation resistance of the connecting plate 410. One end of the first reinforcing plate 500 is welded to the side of the first connecting structure 400, and the other end extends at an inclined angle to the side wall of the first horizontal tube 100 and is welded and fixed.

[0101] This solution forms a two-way support network by symmetrically setting the first support plate 600a and the second support plate 600b, which effectively suppresses the deformation of the first connecting structure 400 under complex loads, enhances the connection stability between the first connecting structure 400, the first horizontal tube 100 and the first reinforcing plate 500, and makes the three form a multi-directional force support system, improving the structural reliability of the steering support horizontal tube 40 when subjected to vibration and impact during vehicle operation, while maintaining the flexibility to adjust the position of the avoidance zone 230.

[0102] Reference Figure 2 and Figure 4 In some embodiments, the steering support cross tube 40 may also include a second connecting structure 700, and the third cross tube 300 may include a fifth end 310 and a sixth end 320 opposite to each other along a first direction, with the fifth end 310 connected to the fourth end 220.

[0103] The second connecting structure 700 refers to the mechanical component used to connect the second horizontal tube 200 and the third horizontal tube 300. Specifically, it can be achieved by welding, bolting, or snap-fit ​​structure. Its function is to provide an adjustable installation interface for the second horizontal tube 200 and the third horizontal tube 300, allowing for fine-tuning of their positions before welding.

[0104] The connection between the fifth end 310 and the fourth end 220 means that the fifth end 310 of the third horizontal pipe 300 and the fourth end 220 of the second horizontal pipe 200 are physically connected through the second connection structure 700. Specifically, this can be achieved by using a socket, plug, or welding method. Its function is to ensure that the relative position between the second horizontal pipe 200 and the third horizontal pipe 300 is adjustable, thereby adapting to the spatial layout requirements of the air outlet 21 of the air conditioner 20.

[0105] In its specific implementation, the second connecting structure 700 is configured to provide temporary fixing during the assembly of the second horizontal tube 200 and the third horizontal tube 300, allowing operators to adjust the installation angle or spacing of the third horizontal tube 300 relative to the second horizontal tube 200 according to the position of the air outlet 21 of the air conditioner 20. After adjustment, the second connecting structure 700 is finally fixed by welding or bolting. For example, the second connecting structure 700 may include a connecting plate 410 with positioning holes, with the fourth end 220 and the fifth end 310 inserted into the corresponding positioning holes respectively. The position of the second horizontal tube 200 is changed by adjusting the insertion depth or angle, followed by welding for fixation.

[0106] This solution introduces a second connecting structure 700, which, while maintaining structural strength, allows for positional adjustability of the connection between the third horizontal pipe 300 and the second horizontal pipe 200, thereby avoiding interference with the air outlet 21 of the air conditioning 20. The adjustable second connecting structure 700 allows the position of the second horizontal pipe 200 to adapt to the air conditioning 20 layout requirements of different vehicle models, while ensuring that the mechanical strength of the connection meets the performance requirements of the steering support assembly.

[0107] Reference Figure 2 and Figure 4 In some embodiments, the second connection structure 700 may include a base plate 710 and a buckle plate 720.

[0108] The base plate 710 has a recess and an opening. The base plate 710 refers to a plate-like substrate that supports the connection function, and can be made from a stamped metal sheet. The recess is formed by a stamping process to accommodate the snap-on plate 720. The opening refers to a notch on the edge of the base plate 710, which can be designed as a U-shape or a rectangle to allow the snap-on plate 720 to be inserted.

[0109] The snap plate 720 is snapped onto the opening and connected to the base plate 710. The snap plate 720, the recess, and the base plate 710 together form a box-like structure with an internal cavity 730.

[0110] The snap-on plate 720 refers to the cover that mates with the base plate 710. Specifically, it can be a bent metal plate that is fixed to the opening of the base plate 710 by welding or bolting. The box structure refers to the enclosed space formed by the base plate 710, the snap-on plate 720, and the recess. Specifically, different shapes of cavities 730 can be formed by adjusting the snap-on angle between the snap-on plate 720 and the base plate 710.

[0111] In practical implementation, the recessed portion of the base plate 710 and the snap-on plate 720 form an internal cavity 730 during assembly. The edge of the snap-on plate 720 is fixedly connected to the opening of the base plate 710 by welding or bolts. When the snap-on plate 720 covers the opening, its bent portion forms a contact surface with the sidewall of the recessed portion of the base plate 710, and the gap between the two constitutes the cavity 730. When the box structure is subjected to external loads, the cavity 730 can disperse stress concentration, and the snap-on connection between the snap-on plate 720 and the base plate 710 forms multi-directional support, thereby improving torsional stiffness.

[0112] Through the above technical solution, the box structure increases the moment of inertia of the cross section through the cavity 730 design. The three-dimensional fastening of the buckle plate 720 and the base plate 710 forms a multi-directional constraint, effectively suppressing local deformation at the connection point. This improves the torsional strength at the connection between the second horizontal tube 200 and the third horizontal tube 300, preventing connection failure due to vibration or impact. At the same time, the cavity 730 structure provides passage space for the second horizontal tube 200 and the third horizontal tube 300, making the horizontal tube layout more flexible. The detachable connection between the buckle plate 720 and the base plate 710 facilitates adjustment of the installation position, adapting to the avoidance requirements of the air conditioning vents 21 of different vehicle models.

[0113] Reference Figure 2 and Figure 4 In some embodiments, the steering support cross tube 40 may further include a second reinforcing plate 800. One end of the second reinforcing plate 800 along a second direction is connected to the second connecting structure 700, and the other end extends obliquely away from the second connecting structure 700 along a first direction and is connected to the third cross tube 300.

[0114] The second reinforcing plate 800 refers to a plate-shaped structure used to enhance the connection strength between the second connecting structure 700 and the third horizontal tube 300. Specifically, it can be a metal plate that is fixed between the second connecting structure 700 and the third horizontal tube 300 by welding or bolting. It forms a triangular support structure by extending at an incline, thereby improving its bending and torsional resistance.

[0115] In some embodiments, the second connecting structure 700 refers to an assembly for connecting the second horizontal tube 200 and the third horizontal tube 300. Specifically, it can be a box-like structure formed by fastening the base plate 710 and the buckle plate 720. The internal cavity 730 can be filled with reinforcing materials, such as foam metal or honeycomb structure, to improve overall rigidity and stability.

[0116] In practical implementation, one end of the second reinforcing plate 800 is connected to the box-shaped sidewall of the second connecting structure 700, and the other end extends at an inclined angle to the sidewall or bottom surface of the third horizontal tube 300, forming a diagonal bracing. For example, the inclination angle of the second reinforcing plate 800 can be any value within the range of 30° to 60°. The second reinforcing plate 800 can be fixed to the base plate 710 of the second connecting structure 700 and the outer surface of the third horizontal tube 300 by welding or riveting, respectively.

[0117] Through the above technical solution, the second reinforcing plate 800 enhances the connection stability between the second connecting structure 700 and the third horizontal tube 300, preventing connection failure due to vehicle vibration or impact. Simultaneously, the inclined extension of the second reinforcing plate 800 disperses the load, reducing the risk of localized stress concentration and ensuring that the clearance area 230 maintains its design shape during long-term use, effectively preventing obstruction of the air outlet 21 of the air conditioner 20. The combination of the second reinforcing plate 800 and the box-type connecting structure ensures connection strength while allowing for flexible adjustment of the position of the third horizontal tube 300, thereby precisely controlling the shape of the clearance area 230.

[0118] Reference Figure 2 and Figure 4 In some embodiments, the steering support transverse may also include a third support plate 900a and a fourth support plate 900b.

[0119] The third support plate 900a is disposed on the second connecting structure 700, with one end connected to the second reinforcing plate 800 and the other end connected to the third horizontal tube 300. The third support plate 900a refers to the plate-like structure connecting the second connecting structure 700 and the third horizontal tube 300. Specifically, it can be implemented by welding and fixing a stamped metal plate, serving to form a rigid support between the second connecting structure 700 and the third horizontal tube 300.

[0120] The fourth support plate 900b is disposed on the second connecting structure 700, with one end connected to the side of the second reinforcing plate 800 facing away from the third support plate 900a, and the other end connected to the third horizontal tube 300. The fourth support plate 900b refers to a plate-like structure symmetrically arranged with the third support plate 900a, and can be manufactured using the same materials and processes as the third support plate 900a, serving to form symmetrical support on the other side of the second reinforcing plate 800.

[0121] In some embodiments, the second connecting structure 700 refers to the assembly connecting the second horizontal tube 200 and the third horizontal tube 300, specifically implemented as a box-like structure formed by the fastening of the base plate 710 and the snap-fit ​​plate 720, with the internal cavity 730 capable of distributing the load. The second reinforcing plate 800 refers to an inclined extending reinforcing member, specifically implemented by welding and fixing a bent steel plate, used to form a triangular support between the second connecting structure 700 and the third horizontal tube 300. The third horizontal tube 300 refers to a tubular component extending along the first direction, specifically implemented by forming a connecting port at the end of a round or square tube.

[0122] In practice, one end of the third support plate 900a is fixed to the surface of the second connecting structure 700 by welding or bolting, and the other end is welded to the side wall of the third horizontal tube 300. The fourth support plate 900b is symmetrically installed on the other side of the second reinforcing plate 800, and its two ends are rigidly connected to the second connecting structure 700 and the third horizontal tube 300, respectively.

[0123] The inclined extension of the second reinforcing plate 800 forms a triangular stable structure with the second connecting structure 700 and the third horizontal tube 300. The third support plate 900a and the fourth support plate 900b provide additional support on both sides of the triangular structure, forming a cross-support system. When subjected to torque, the box-shaped cavity 730 of the second connecting structure disperses stress through its internal cavity 730, while the cross arrangement of the third support plate 900a and the fourth support plate 900b further suppresses the deformation of the box-shaped structure.

[0124] Through the above technical solution, by setting symmetrically arranged support plates between the second connecting structure 700 and the third horizontal tube 300, the load transmission path is expanded from a single line to multiple lines. Simultaneously, the synergistic effect of the box-type connecting structure and the triangular reinforcement structure significantly improves the torsional stiffness and fatigue resistance of the connection part, achieving a dual improvement in the connection stability between the second connecting structure 700 and the third horizontal tube 300. This design effectively suppresses deformation and displacement of the connection part under vehicle bumpy conditions, avoiding the risk of connection failure due to long-term vibration, and at the same time provides a stable structural foundation for the avoidance zone 230 of the air conditioner 20's air outlet 21.

[0125] Reference Figure 1 This application embodiment also provides a vehicle, which may include a vehicle body and the aforementioned steering support cross tube 40.

[0126] Through the above technical solution, this application can flexibly adjust the avoidance zone 230 according to the position of the air outlet 21 of the air conditioner 20 to avoid blocking the air outlet path. At the same time, the connection structure and the reinforcing plate ensure the mode and strength of the steering support cross tube 40, so as to meet the arrangement requirements of the instrument panel assembly for the steering column 30 and the airbag 10.

[0127] In some embodiments, the vehicle may be a gasoline-powered vehicle, or it may be a new energy vehicle, such as a pure electric vehicle (PEV / BEV), a range-extended electric vehicle (REEV), a hybrid electric vehicle (HEV), or a fuel cell electric vehicle. The vehicle may also be any vehicle equipped with a battery.
