[0001] This utility model relates to the field of automotive body structure technology, and in particular to a side beam structure for an automobile and an automobile. Background Technology

[0002] A car body typically integrates structures such as air conditioning ducts, interior panels, sunroof, and side beams. The sunroof is installed on the roof and serves to enhance the driving and riding experience; the air conditioning ducts are installed on the side of the sunroof or inside the body floor to connect with the air conditioning unit and the cabin for air exchange; the side beams are located on the outermost side of the frame structure and are the core load-bearing structure on the side of the vehicle; the interior panels cover the inside of the side beams and mainly serve a decorative and protective function.

[0003] Integrating multiple structures within the confined space of a car presents several challenges. First, it increases structural complexity, overall vehicle weight, and costs. Second, the distributed arrangement of these structures inevitably leads to interference in spatial layout, affecting the technological feel of the cabin. More importantly, air conditioning ducts, interior panels, and other components occupy significant cabin space, compressing passenger movement space and even side beam installation space. If side beam space is squeezed and the side beam size is reduced, it can create serious safety hazards and potentially endanger passenger lives. Utility Model Content

[0004] The purpose of this utility model is to solve the problem in the prior art that air conditioning ducts, interior panels, etc. occupy a lot of cabin space, resulting in the compression of passenger activity space and even side beam installation space.

[0005] To solve the above-mentioned technical problems, the present invention discloses a side beam structure for an automobile, comprising: an outer panel and an inner panel, both extending in the length direction of the automobile; in the width direction of the automobile, the outer panel and the inner panel are arranged opposite to each other and located outside the inner panel; the outer panel and the inner panel are connected and together define a receiving cavity; a protective coating is applied to the side of the inner panel away from the outer panel; and an internally hollow air conditioning duct is disposed in the receiving cavity and extends along the extension direction of the outer panel and the inner panel, with one end of the air conditioning duct connected to an air conditioning unit.

[0006] By adopting the above technical solution, the air conditioning ducts are placed within the cavity formed by the outer and inner panels, changing the original distributed and independent arrangement of the air conditioning ducts and side beam structure. The cavity space is used as the installation space for the air conditioning ducts, achieving space reuse, improving space utilization, and leaving more space for passenger movement and the installation of other components. Furthermore, the air conditioning ducts can replace the original side beam support plates, acting as support components for the side beam structure, reducing component costs and overall vehicle weight. Further, the protective coating applied to the side of the inner panel away from the outer panel utilizes its wear resistance, corrosion resistance, stain resistance, noise reduction, and fire resistance properties to prevent the inner panel from being eroded, contaminated, or damaged. Different colors or textures of the protective coating can also serve a decorative purpose. The inner panel not only ensures vehicle strength but also serves as a protective and decorative interior panel, thus replacing the original interior panels, further saving interior space, improving space utilization, and leaving more space for passenger movement and the installation of other components.

[0007] According to another specific embodiment of the present invention, the protective coating of the side beam structure of the automobile disclosed in the embodiment of the present invention includes: a protective resin coating or a protective paint coating.

[0008] By adopting the above technical solutions, the anti-slip properties, dirt resistance, and noise reduction of the protective resin coating can improve the tactile feel and durability of the inner panel; and the rich appearance colors of the protective paint coating can enhance the decorative properties of the inner panel.

[0009] According to another specific embodiment of the present invention, the side beam structure of the automobile disclosed in this embodiment has a top wall and a first side wall forming a receiving cavity on the wall surface of the outer panel facing the inner panel, and a bottom wall and a second side wall forming a receiving cavity on the wall surface of the inner panel facing the outer panel. In the height direction of the automobile, the top wall and the bottom wall are arranged opposite to each other and are located above the bottom wall. In the width direction of the automobile, the first side wall and the second side wall are arranged opposite to each other and are located outside the second side wall. Furthermore, the bottom wall of the receiving cavity extends downward from the second side wall towards the first side wall, and the angle of inclination formed by the bottom wall relative to the horizontal plane is in the range of 5° to 45°. The end of the bottom wall near the first side wall is connected to an air conditioning water collection component.

[0010] By adopting the above technical solution, the bottom wall of the receiving cavity is set to extend downward, so that the condensate water condensed on the outer wall of the air conditioning duct during the operation of the air conditioner flows to the bottom of the air conditioning duct under the action of gravity and collects in the air conditioning water collection component along the bottom wall of the inclined receiving cavity, so as to facilitate collection and prevent the condensate water from accumulating in the receiving cavity.

[0011] According to another specific embodiment of the present invention, the side beam structure of the automobile disclosed in this embodiment of the present invention has a plurality of guide grooves formed on the outer wall surface of the air conditioning duct; wherein, the plurality of guide grooves are arranged in a ring-shaped interval along the circumference of the air conditioning duct, and each guide groove extends along the extension direction of the air conditioning duct and extends from one end of the air conditioning duct to the other end; or, the plurality of guide grooves are arranged at intervals along the extension direction of the air conditioning duct, and each guide groove is configured as an annular groove extending along the circumference of the air conditioning duct.

[0012] Using the above technical solution, multiple guide grooves formed on the outer wall of the air conditioning duct can collect condensate in the grooves, and the extension direction of multiple guide layers is consistent, which makes it easy to collect condensate in the same place along the same direction.

[0013] According to another specific embodiment of the present invention, the side beam structure of the automobile disclosed in the embodiment of the present invention has an air conditioning duct covered with a water-absorbing layer on its outer wall. The water-absorbing layer extends along the extension direction of the air conditioning duct and extends from one end of the air conditioning duct to the other end.

[0014] By adopting the above technical solution, the water-absorbing layer covering the outer wall of the air conditioning duct can absorb the condensate on the outer wall of the air conditioning duct, preventing the condensate from directly contacting the wall of the receiving cavity for a long time and causing corrosion.

[0015] According to another specific embodiment of the present invention, in the side beam structure of the automobile disclosed in this embodiment, the outer wall surface of the air conditioning duct contacts the wall surface of the outer panel defining the receiving cavity, and also contacts the wall surface of the inner panel defining the receiving cavity.

[0016] By adopting the above technical solution, the outer wall of the air conditioning duct contacts the wall of the receiving cavity, so that the air conditioning duct makes full use of the space inside the receiving cavity and forms a stable support structure by contacting the wall of at least two receiving cavities, thereby improving the support performance.

[0017] According to another specific embodiment of the present invention, the side beam structure of the automobile disclosed in the embodiment of the present invention is such that, in the width direction of the automobile, the corresponding ends of the outer panel and the inner panel are fixedly connected, the outer wall surface of the air conditioning duct is fixedly connected to the wall surface of the outer panel defining the receiving cavity, and is fixedly connected to the wall surface of the inner panel defining the receiving cavity; or, the outer panel, the inner panel and the air conditioning duct are integrally cast or integrally extruded.

[0018] Using the above technical solution, the air conditioning duct and the outer and inner panels are connected in a separate manner, which facilitates installation and disassembly; the air conditioning duct and the outer and inner panels are formed in one step at the mold stage by casting or integral extrusion molding, which reduces processing steps and makes the connection between the various components more stable and reliable.

[0019] According to another specific embodiment of the present invention, the side beam structure of the automobile disclosed in the embodiment of the present invention has an air conditioning duct with a cross-section of any one of the following: circular, rectangular, or polygonal; the air conditioning duct is made of any one of the following materials: steel, carbon fiber, or polymer.

[0020] This utility model also provides an automobile, including the side beam structure of the automobile provided in the above specific embodiments.

[0021] By adopting the above technical solution, and using the side beam structure of the aforementioned vehicle, the space of the accommodating cavity is used as the installation space for the air conditioning duct, thus achieving space reuse, improving space utilization, and leaving more space for passenger movement and the installation of other components. Furthermore, replacing the original side beam support plate with the air conditioning duct reduces parts costs and overall vehicle weight. The inner panel can replace the original interior trim panel, further saving interior space and improving space utilization.

[0022] According to another specific embodiment of the present invention, the automobile disclosed in this embodiment includes an A-pillar assembly, the A-pillar assembly includes an exterior trim panel and a side beam structure, and in the width direction of the automobile, the exterior trim panel is located outside the side beam structure.

[0023] By adopting the above technical solution, including the side beam structure A-pillar assembly provided in the above specific embodiments, the interior trim panel is no longer required compared to the original A-pillar assembly, which improves the space utilization rate in the cabin. Furthermore, after the air conditioning duct is placed in the receiving cavity, the air conditioning duct no longer needs to occupy the space on both sides of the sunroof, thereby avoiding the problem of installation interference between the air conditioning duct and the sunroof or other components at the roof.

[0024] The beneficial effects of this utility model are:

[0025] This utility model provides a side beam structure and a vehicle including the side beam structure. The air conditioning duct is housed within a cavity formed by the outer and inner panels, utilizing the cavity space as the installation space for the air conditioning duct. This reuse of the cavity space improves space utilization, leaving more space for passenger movement and the installation of other components. Furthermore, the air conditioning duct can replace the original side beam support plate, acting as a support component for the side beam structure, reducing component costs and overall vehicle weight. Further, a protective coating applied to the side of the inner panel away from the outer panel prevents corrosion, contamination, or damage. Different colors or textures of the protective coating also serve a decorative purpose. Thus, the inner panel can replace the original interior trim panels, further saving interior space, improving space utilization, and leaving more space for passenger movement and the installation of other components.

[0039] A car body typically integrates structures such as air conditioning ducts, interior panels, sunroofs, and side beams. The sunroof is installed on the roof and serves to enhance the driving and riding experience. The air conditioning ducts are installed on the side of the sunroof or inside the vehicle floor to connect with the air conditioning unit and the cabin for air exchange. The side beams are located on the outermost side of the frame structure, including A-pillar side beams and sill side beams, and are the core load-bearing structures on the side of the vehicle. The interior panels cover the inside of the side beams and mainly serve a decorative and protective function.

[0040] For example, the Y-axis space at the top of the vehicle includes various components such as the A-pillar side beam, air duct, sunroof, roof screen, interior trim panels, and sliding door tracks. One existing distribution structure for automotive air duct, interior trim panels, and side beam assemblies is as follows: Figure 1As shown, the A-pillar side beam 1′, as a separate component, comprises an outer side beam 10′, an inner side beam 11′, and a reinforcing plate 12′. The reinforcing plate 12′ is pre-welded to the outer side beam 10′ and the inner side beam 11′. During the final assembly stage, the air duct 3 and the interior trim panel 4 are installed. Furthermore, the air duct 3 on the vehicle roof is arranged parallel to the A-pillar side beam 1′. The cross-sectional dimensions of the A-pillar side beam 1′ must meet relevant regulatory requirements to ensure that it possesses appropriate strength and rigidity.

[0041] Therefore, integrating multiple structures within the confined space of a car presents several challenges. First, it increases structural complexity, overall vehicle weight, and costs. Second, the distributed arrangement of these multiple structures inevitably leads to interference in spatial layout, affecting the technological feel of the cabin. More importantly, air conditioning ducts, interior panels, and other components occupy significant cabin space, compressing passenger movement space and even side beam installation space. If side beam space is squeezed and the side beam size is reduced, it can create serious safety hazards and potentially endanger passenger lives.

[0042] To address the aforementioned issues, this utility model provides a side beam structure for automobiles, comprising an outer panel, an inner panel, and a hollow air conditioning duct. The air conditioning duct is disposed within a cavity formed by the outer and inner panels, thereby improving the space utilization of the cavity. A protective coating is applied to the side of the inner panel away from the outer panel, giving the inner panel both protective and decorative functions, thus replacing the interior trim panel and further improving space utilization.

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0044] Example 1

[0045] This embodiment provides a side beam structure for an automobile, such as... Figure 2 and Figure 3 As shown, the side beam structure 1 of the automobile includes an outer plate 10 and an inner plate 11, both of which extend in the length direction of the automobile and in the width direction of the automobile. Figure 2 and Figure 3(In the direction of arrow Y in the figure), the outer panel 10 is disposed opposite to the inner panel 11 and is located outside the inner panel 11. That is, in the width direction of the vehicle, the inner panel 11 is closer to the middle of the vehicle than the outer panel 10. Furthermore, the outer panel 10 and the inner panel 11 are connected and together define a receiving cavity 12. The side beam structure 1 of the vehicle also includes an internally hollow air conditioning duct 13, which is disposed in the receiving cavity 12 and extends along the extension direction of the outer panel 10 and the inner panel 11. One end of the air conditioning duct 13 is connected to the air conditioning unit (not shown in the figure). By placing the air conditioning duct 13 within the cavity 12 formed by the outer panel 10 and the inner panel 11, without altering the cross-sectional dimensions of the vehicle's side beam structure 1, the original distributed and independent arrangement of the air conditioning duct 13 and the side beam structure 1 is changed. The space of the cavity 12 is used as the installation space for the air conditioning duct 13, ensuring that the strength and rigidity of the side beam structure 1 are not weakened. This achieves space reuse, improves space utilization, and leaves more space for passenger movement and the installation of other components. Furthermore, the air conditioning duct 13 can replace the original side beam support plate, serving as a support component for the side beam structure 1, reducing component costs and overall vehicle weight. Experimental verification shows that placing the air conditioning duct 13 within the cavity 12 significantly improves the vehicle body's rigidity and strength performance, increasing torsional rigidity by over 1000 N / mm. Simultaneously, the improved performance makes the force transmission path of the vehicle body smoother, further reducing weight due to increased efficiency.

[0046] Furthermore, the inner panel 11 is coated with a protective coating on the side facing away from the outer panel 10, i.e., the side of the inner panel 11 facing the vehicle cabin is coated with a protective coating. Utilizing the wear-resistant, corrosion-resistant, stain-resistant, noise-reducing, and fire-retardant properties of the protective coating, the inner panel 11 can be prevented from being corroded, contaminated, or damaged. Different colors or textures of the protective coating can also serve a decorative purpose. The inner panel 11 can both ensure the strength of the vehicle and serve as a protective and decorative interior panel. Thus, the inner panel 11 can replace the original interior panel, further saving interior space, improving space utilization, and leaving more space for passenger movement and the installation of other components. After testing and verification, the solution of replacing the reinforcing plate of the side beam structure 1 of the car with the air conditioning duct 13 and replacing the interior panel with the inner panel 11 can reduce the overall vehicle weight by 10-20 kg while meeting regulatory collision requirements.

[0047] In one specific embodiment, the protective coating includes a protective resin coating or a protective paint coating.

[0048] Specifically, the anti-slip properties, dirt resistance, and noise reduction of the protective resin coating can improve the tactile feel and durability of the inner panel 11; the rich colors of the protective paint coating can enhance the decorative properties of the inner panel 11.

[0049] In one specific embodiment, the cross-section of the air conditioning duct 13 is any one of a circle, rectangle, or polygon; the air conditioning duct 13 is made of any one of steel, carbon fiber, or polymer materials.

[0050] Specifically, because the air conditioning duct 13 has an internal hollow structure, regardless of whether its cross-section is circular, rectangular, or polygonal, the air conditioning duct 13 can provide multi-point support to the outer panel 10 and inner panel 11 within the receiving cavity 12, resulting in better support performance compared to the original plate-shaped reinforcing plate. For example... Figure 2 and Figure 3 As shown, the cross-section of the air conditioning duct 13 is preferably set to be circular.

[0051] In one specific implementation, such as Figure 2 and Figure 3 As shown, the outer wall of the air conditioning duct 13 is in contact with the wall of the outer panel 10 that defines the receiving cavity 12, and is also in contact with the wall of the inner panel 11 that defines the receiving cavity 12.

[0052] Specifically, by having the outer wall of the air conditioning duct 13 contact the wall of the receiving cavity 12 respectively, the air conditioning duct 13 makes full use of the space inside the receiving cavity 12 and forms a stable support structure by contacting the walls of at least two receiving cavities 12, thereby improving the support performance of the air conditioning duct 13.

[0053] In one specific embodiment, the air conditioning duct 13 is connected to the outer panel 10 and the inner panel 11 in a split connection manner. In the width direction of the vehicle, the corresponding ends of the outer panel 10 and the inner panel 11 are fixedly connected. Specifically, welding, screwing or riveting can be used, as long as a stable and reliable connection between the outer panel 10 and the inner panel 11 can be ensured.

[0054] The outer wall of the air conditioning duct 13 is fixedly connected to the wall of the outer panel 10 that defines the receiving cavity 12, and is also fixedly connected to the wall of the inner panel 11 that defines the receiving cavity 12. Specifically, welding, screwing, or riveting can be used, as long as a stable and reliable connection between the air conditioning duct 13 and the outer panel 10 and the inner panel 11 can be ensured. The split connection method facilitates installation and disassembly.

[0055] Alternatively, the outer panel 10, inner panel 11, and air conditioning duct 13 can be integrally cast or extruded in one piece during the mold stage, making the connection between the components more stable and reliable. Furthermore, the assembly station can be eliminated on the final assembly line, reducing processing steps and assembly line costs.

[0056] It should be noted that when the outer panel 10, inner panel 11 and air conditioning duct 13 are integrally formed, the three are made of the same material, such as steel.

[0057] In one specific implementation, such as Figure 2 and Figure 3 As shown, the outer panel 10 facing the inner panel 11 forms the top wall 120 and the first side wall 121 of the receiving cavity 12. The inner panel 11 facing the outer panel 10 forms the bottom wall 122 and the second side wall 123 of the receiving cavity 12. In the height direction of the vehicle, the top wall 120 is arranged opposite to the bottom wall 122 and is located above the bottom wall 122. In the width direction of the vehicle, the first side wall 121 is arranged opposite to the second side wall 123 and is located outside the second side wall 123, that is, the first side wall 121 is located on the side of the second side wall 123 facing the vehicle compartment. The angle formed by the top wall surface 120 and the first side wall surface 121 can be 90°, or greater than 90° or less than 90°; the angle formed by the bottom wall surface 122 and the second side wall surface 123 can be 90°, or greater than 90° or less than 90°, and the top wall surface 120 and the first side wall surface 121, as well as the bottom wall surface 122 and the second side wall surface 123, can all transition smoothly, so that the cross-section of the receiving cavity 12 formed by the outer plate 10 and the inner plate 11 is in a "quadrilateral" shape.

[0058] Furthermore, the bottom wall 122 of the receiving cavity 12 extends downward from the second side wall 123 toward the first side wall 121, and the angle of inclination of the bottom wall 122 relative to the horizontal plane is in the range of 5° to 15°; the end of the bottom wall 122 near the first side wall 121 is connected to the air conditioning water collection component (not shown in the figure).

[0059] Specifically, by setting the bottom wall surface 122 of the receiving cavity 12 to extend downward, the condensate water that condenses on the outer wall of the air conditioning duct 13 during air conditioning operation flows to the bottom of the air conditioning duct 13 under the action of gravity and flows along the bottom wall surface 122 of the inclined receiving cavity 12 to the lowest point, and collects in the air conditioning water collection component for easy collection and to prevent condensate water from accumulating in the receiving cavity 12.

[0060] In another specific implementation, such as Figure 2 As shown, a plurality of guide grooves 130 are formed on the outer wall surface of the air conditioning duct 13; wherein, the plurality of guide grooves 130 are arranged in a ring-shaped interval along the circumference of the air conditioning duct 13, and each guide groove 130 extends along the extension direction of the air conditioning duct 13 and extends from one end of the air conditioning duct 13 to the other end. Alternatively, the plurality of guide grooves 130 are arranged at intervals along the extension direction of the air conditioning duct 13, and each guide groove 130 is configured as a ring groove extending along the circumference of the air conditioning duct 13.

[0061] Specifically, the multiple guide grooves 130 formed on the outer wall of the air conditioning duct 13 can collect condensate in the grooves, and the extension direction of the multiple guide layers is consistent, which makes it easy to collect condensate in the same place along the same direction.

[0062] It should be noted that when multiple guide channels 130 are arranged in a ring-shaped interval along the circumference of the air conditioning duct 13, and each guide channel 130 extends along the extension direction of the air conditioning duct 13, condensate can flow along the extension direction of the air conditioning duct 13 to be discharged outside the side beam structure 1 of the vehicle. When multiple guide channels 130 are arranged at intervals along the extension direction of the air conditioning duct 13, and each guide channel 130 is set as an annular channel extending along the circumference of the air conditioning duct 13, condensate can flow along the circumference of the air conditioning duct 13 and collect at the bottom of the air conditioning duct 13 under the action of gravity, and be drained outside the side beam structure 1 of the vehicle or absorbed by the water absorption component. When the bottom wall surface 122 extends downward from the second side wall surface 123 toward the first side wall surface 121, it can flow along the bottom wall surface 122 into the air conditioning water collection component.

[0063] It should also be noted that the number of guide channels 130 is determined according to the size of the air conditioning duct 13. For example, it can be set to 3, 5, 8 or 10, etc., and no specific limit is made here.

[0064] In one specific implementation, such as Figure 3 As shown, the outer wall of the air conditioning duct 13 is covered with a water-absorbing layer 14, which extends along the extension direction of the air conditioning duct 13 and extends from one end of the air conditioning duct 13 to the other end.

[0065] Specifically, the water-absorbing layer 14 covering the outer wall of the air conditioning duct 13 can absorb the condensate on the outer wall of the air conditioning duct 13, preventing the condensate from directly contacting the wall of the receiving cavity 12 for a long time and causing corrosion.

[0066] It should be noted that the absorbent layer 14 can be made of sponge, absorbent resin, cotton cloth, etc., as long as it can wrap around the outside of the air conditioning duct 13 and has water absorption properties.

[0067] It should also be noted that when multiple guide grooves 130 are formed on the outer wall of the air conditioning duct 13, the water absorption layer 14 can cover the outside of the multiple guide grooves 130 to absorb the condensate water accumulated in the guide grooves 130.

[0068] Example 2

[0069] This embodiment provides a vehicle including the side beam structure of the vehicle provided in Embodiment 1. By adopting this side beam structure on the vehicle, the space of the accommodating cavity is used as the installation space for the air conditioning duct, realizing the reuse of the accommodating cavity space, improving space utilization, and leaving more space for passenger movement in the cabin and the installation of other components. Furthermore, the air conditioning duct replaces the original side beam support plate, reducing parts costs and overall vehicle weight. The inner panel can replace the original interior trim panel, further saving interior space and improving space utilization.

[0070] It should be noted that the side beam structure can be located at the top of the car, such as the A-pillar side beam; or at the bottom of the car, such as the door sill side beam.

[0071] According to another specific embodiment of the present invention, the automobile disclosed in this embodiment includes an A-pillar assembly, the A-pillar assembly includes an exterior trim panel and a side beam structure, and in the width direction of the automobile, the exterior trim panel is located outside the side beam structure.

[0072] Specifically, the A-pillar assembly with this side beam structure no longer requires interior trim panels compared to the original A-pillar assembly, improving the space utilization rate in the cabin. Furthermore, with the air conditioning duct installed inside the cavity, the air conditioning duct no longer needs to occupy the space on both sides of the sunroof, thus avoiding the problem of installation interference between the air conditioning duct and the sunroof or other components at the roof.

[0073] Because this side beam structure can save interior space, low-roof vehicles can achieve extremely low body height and ultra-low wind resistance; high-roof vehicles can gain a competitive advantage in space across classes, and can be equipped with larger roof screens or sunroofs, enhancing the driving and riding experience.
