[0001] This disclosure claims priority to Chinese patent application No. 202410328298.2, filed on March 20, 2024, with invention name “Automobile”, the entire contents of which are incorporated herein by reference. Technical Field
[0002] The present disclosure relates to the technical field of automobile ventilation, and in particular to an automobile. Background Art
[0003] In a complete vehicle, the air conditioning system usually includes air conditioning, air ducts and air outlets. The air ducts and air outlets are responsible for delivering the processed airflow (such as temperature processing, humidity processing and purification processing, etc.) to the ventilation task in the passenger compartment of the vehicle to complete the functions of ventilation, cooling, heating, defrosting, demisting and air purification in the passenger compartment.
[0004] As people's requirements for automobile performance, functions and human-machine interfaces become higher and higher, more and more parts are integrated into the entire vehicle, resulting in insufficient space for the current air duct layout. Summary of the Invention
[0005] The present disclosure provides a car, the air duct of which can be arranged in a cavity of a car beam, which not only achieves the concealment of the air duct but also reduces the space inside the car occupied by the air duct, thereby alleviating the problem of insufficient space for the arrangement of the air duct in the car.
[0006] The present disclosure provides a car, comprising an onboard air conditioner, an air duct, an air outlet, and a car beam, wherein the car beam has a cavity along a length direction;
[0007] The vehicle beam includes a first vehicle beam, the air duct includes a first air duct, the first air duct is installed in a cavity of the first vehicle beam and is connected to the vehicle air conditioner, and the air outlet includes a first air outlet, the first air outlet is located inside the vehicle and is connected to the first air duct.
[0008] The beam, serving as the vehicle's skeleton, includes pillars, crossbeams, and longitudinal beams. Each beam has a cavity along its length. Therefore, an air duct can be installed in the cavity of the beam. Therefore, the beam with the air duct installed can be denoted as the first beam.
[0009] Among them, the air duct connecting the vehicle air conditioner and the air outlet can be arranged in the cavity of the vehicle beam or at other positions. Then, the air duct arranged in the cavity of the vehicle beam is recorded as the first air duct.
[0010] Among them, the car has many air outlets, so the air outlet connected to the first air duct is recorded as the first air outlet.
[0011] In the solution shown in the present disclosure, the first air duct is installed in the cavity of the first vehicle beam, and the cavity of the vehicle beam does not belong to the interior space of the vehicle. Therefore, such arrangement of the first air duct not only achieves the concealment of the first air duct, but also reduces the interior space occupied by the air duct, thereby alleviating the problem of insufficient space in the air duct arrangement.
[0012] In a possible implementation, the first vehicle beam includes an inner sheet metal part and an outer sheet metal part, and the cavity is formed between the inner sheet metal part and the outer sheet metal part.
[0013] In the solution shown in the present disclosure, the first air duct is arranged in the cavity formed between the inner sheet metal and the outer sheet metal of the first vehicle beam, and is not arranged between the inner sheet metal and the interior trim panel. The space between the inner sheet metal and the outer sheet metal does not belong to the interior space of the vehicle, and the space between the inner sheet metal and the interior trim panel belongs to the interior space of the vehicle. Therefore, the arrangement of the first air duct in this way can reduce the space occupied by the air duct in the vehicle.
[0014] In a possible implementation, the first air duct is installed on the inner wall of the chamber through a bracket.
[0015] In the solution shown in the present disclosure, the first air duct can be directly fixed on the inner wall of the chamber, but the first air duct is installed on the inner wall of the chamber through a bracket, which can achieve lossless installation of the first air duct and avoid air leakage in the first air duct.
[0016] In a possible implementation, the first end of the bracket is fixed to the first inner wall of the chamber, and the second end is fixed to the first inner wall of the chamber along the circumference of the first air duct, bypassing the first air duct.
[0017] In the solution disclosed herein, the bracket can be an integrated bracket. The first end of the bracket can be first fixed to the first inner wall of the chamber, and then the other end can bypass the first air duct and be fixed to the first inner wall of the chamber. In this way, the integrated bracket clamps the first air duct to the first inner wall of the chamber. This solution of fixing the first air duct with an integrated bracket only requires fixing both ends of the bracket to the same inner wall of the chamber. There is no fixed relationship between the first air duct and the chamber, and there is no fixed relationship between the first air duct and the bracket. In this way, the first air duct can be installed without damage, avoiding air leakage in the first air duct.
[0018] In one possible implementation, the bracket includes a first bracket and a second bracket, the first end of the first bracket is fixed to the first position of the first air duct, and the second end is fixed to the first inner wall of the chamber, the first end of the second bracket is fixed to the second position of the first air duct, and the second end is fixed to the first inner wall of the chamber, wherein the first position and the second position of the first air duct are located at different positions of the first air duct.
[0019] In the solution shown in the present disclosure, the bracket can be a split bracket, including a first bracket and a second bracket, through which the first air duct is fixed to the inner wall of the chamber. Compared with the integrated bracket, the split bracket uses less material, which is conducive to saving materials and reducing weight.
[0020] In a possible implementation, there are multiple brackets, and the multiple brackets are arranged at intervals along the length direction of the first air duct.
[0021] In the solution shown in the present disclosure, since the first air duct has a certain length, a plurality of brackets can be used and arranged at intervals along the length direction of the first air duct, so as to firmly fix the first air duct in the chamber.
[0022] In a possible implementation, a foam material is filled between the inner wall of the chamber and the outer wall of the first air duct.
[0023] In the solution disclosed herein, a foam material is filled between the inner wall of the chamber and the outer wall of the first air duct. This material not only secures the first air duct within the chamber, but also absorbs noise and vibration generated by the first air duct. Thus, the foam material provides both stability and noise and vibration reduction.
[0024] In a possible implementation, a cross-sectional area of the first air duct is greater than or equal to half of a cross-sectional area of the chamber, and smaller than the cross-sectional area of the chamber.
[0025] In the solution disclosed herein, the first air duct has a relatively large cross-sectional area, enabling it to function as a reinforcement tube, thereby increasing the strength and rigidity of the vehicle. For example, if the first air duct is made of metal and has a relatively large cross-sectional area, it can function as a reinforcement tube, thereby serving as both an air duct and a structural component.
[0026] In a possible implementation, the first air duct is made of metal or plastic.
[0027] In the solution shown in the present disclosure, the material of the first air duct is metal, especially a metal material with relatively high rigidity and strength, which enables the first air duct to be used as a structural component.
[0028] In one possible implementation, the vehicle air conditioner includes a first vehicle air conditioner and a second vehicle air conditioner, the first vehicle air conditioner is installed in the engine compartment of the car, the second vehicle air conditioner is installed in the trunk of the car, and the first air duct is connected to the second vehicle air conditioner.
[0029] In the solution shown in the present disclosure, the car includes two on-board air conditioners, one installed in the engine compartment to provide a comfortable interior environment for the occupants in the cockpit and the co-pilot compartment, and the other installed in the trunk to provide a relatively comfortable interior environment for the rear passengers.
[0030] In a possible implementation, the automobile includes a front pillar, a rear pillar, and a pillar upper side beam connecting the front pillar and the rear pillar, and the first vehicle beam includes the pillar upper side beam and the rear pillar.
[0031] In the solution shown in the present disclosure, the first air duct may pass through the cavity of the rear pillar, extend into the cavity of the upper side beam of the pillar, and then communicate with the first air outlet.
[0032] In the solution shown in the present disclosure, the front pillar is the A-pillar of the car, the rear pillar is the C-pillar, and the upper side beam of the pillar is the upper side beam located above the B-pillar. In this way, the first air duct can pass through the cavity of the C-pillar and extend into the cavity of the upper side beam of the pillar.
[0033] In the solution shown in the present disclosure, the front pillar is the A-pillar of the car, the rear pillar is the D-pillar, and the upper side beam of the pillar is the upper side beam located above the B-pillar and the C-pillar. In this way, the first air duct can pass through the cavity of the D-pillar and extend into the cavity of the upper side beam of the pillar. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.
[0044] This embodiment relates to an automobile, specifically to an automobile air conditioning system. The automobile air conditioning system primarily includes an onboard air conditioner, air ducts, and air outlets. The onboard air conditioner is typically located in the engine compartment, and the air outlets generally include front and rear air outlets. The front air outlets are typically located in the center of the central instrument panel and near the windows on both sides, while the rear air outlets are typically located behind a storage box between the driver's seat and the front passenger seat. The air ducts connect the onboard air conditioner to the various air outlets. For example, the air duct between the onboard air conditioner and the rear air outlet on the rear side of the storage box is located in the center aisle of the automobile.
[0045] Among them, the car's air-conditioning system is used to realize in-car air circulation and in-car temperature control, providing a comfortable in-car environment for the driver and passengers. However, for large cars, such as cars with a wheelbase greater than 3 meters, or D-class cars, the rear space is relatively large. It is difficult to provide a comfortable in-car environment for the rear passengers only with the help of the rear air outlet on the rear side of the storage box.
[0046] For this reason, some large cars will be equipped with an additional car air conditioner. In this way, the car includes two car air conditioners, which are respectively recorded as the first car air conditioner and the second car air conditioner. Among them, the first car air conditioner serves as the main car air conditioner and is still arranged in the engine compartment, and the second car air conditioner serves as the auxiliary car air conditioner and is arranged on the rear side of the car.
[0047] The air ducts and air outlets connected to the first air conditioner generally follow the previous layout. As mentioned above, the front air outlets are located in the center of the center console and near the windows on both sides, the rear air outlets are located behind the storage box, and the air ducts connected to the rear air outlets are placed in the central channel. The air ducts connected to the second air conditioner are generally arranged on the outer surface of the inner sheet metal of the white body. The outer surface of the inner sheet metal is then covered with interior trim, thereby concealing the air ducts fixed to the inner sheet metal. The air outlets connected to the second air conditioner face inwards and are located in the rear passenger compartment.
[0048] However, the air duct connected to the second vehicle air conditioner is arranged on the outer surface of the inner sheet metal, which will occupy the interior space of the entire vehicle and is not conducive to improving the integration level of the entire vehicle. Moreover, occupying the interior space of the entire vehicle will make the rear space of the vehicle more crowded, which will reduce the riding comfort of the rear passengers to a certain extent.
[0049] To this end, this embodiment provides a car whose air duct can be arranged in a cavity of the car beam, which not only hides the air duct without affecting the appearance, but also does not occupy the space inside the car, and has a high degree of integration.
[0050] The car includes an on-board air conditioner, an air duct, an air outlet and a vehicle beam, wherein the air duct is connected to the exhaust outlet of the on-board air conditioner, and the air outlet is connected to the air duct, so that the on-board air conditioner can deliver appropriate airflow to the air outlet through the air duct.
[0051] Among them, the vehicle beam includes the vehicle's pillars (such as the A-pillar, B-pillar, C-pillar and D-pillar), the upper side beams located on the side of the vehicle, and the cross beams located on the top of the vehicle.
[0052] As shown in Figure 1, which is a schematic cross-sectional view of a vehicle beam, the first vehicle beam 1 includes an inner sheet metal component 11, an outer sheet metal component 12, and a side outer panel 13. A cavity 10 is formed between the inner sheet metal component 11 and the outer sheet metal component 12, and a cavity is also formed between the outer sheet metal component 12 and the side outer panel 13.
[0053] Then, the air duct connecting the car air conditioner and the air outlet can be installed in the cavity of the car beam. In this way, the air duct is hidden without affecting the appearance, and it does not occupy the space inside the car, with a high degree of integration.
[0054] In one example, not all cavities of the vehicle beams need to be installed with air ducts, and not all air ducts need to be installed in the cavities of the vehicle beams (of course, all air ducts can also be installed in the cavities of the vehicle beams). Therefore, the vehicle beam can include a first vehicle beam 1, and the air duct can include a first air duct 2, wherein the first vehicle beam 1 is one or more vehicle beams in which air ducts are installed in their cavities, and the first air duct 2 is a section of the air duct installed in the cavity of the vehicle beam.
[0055] Likewise, not all air outlets are connected to the first air duct 2 . The air outlets connected to the first air duct 2 may be referred to as first air outlets, which are arranged toward the interior of the vehicle.
[0056] In one example, the first air duct 2 is connected to the vehicle air conditioner, and the first end of the first air duct 2 can be directly connected to the exhaust port of the vehicle air conditioner, or the first end of the first air duct 2 can be indirectly connected to the exhaust port of the vehicle air conditioner through another air duct. Similarly, the first air duct 2 is connected to the first air outlet, and the second end of the first air duct 2 can be directly connected to the first air outlet, or the second end of the first air duct 2 can be indirectly connected to the first air outlet through another air duct.
[0057] In one example, the first air duct 2 is installed in the cavity 10 of the first beam 1. The first air duct 2 can be installed in the cavity 10 between the inner sheet metal 11 and the outer sheet metal 12, or in the cavity between the side panel 13 and the outer sheet metal 12. This embodiment does not limit this. In actual installation, a cavity with a larger cross-sectional area is selected to install the first air duct. Generally, the cross-sectional area of the cavity between the inner sheet metal 11 and the outer sheet metal 12 of the first beam 1 is relatively large. Therefore, the following examples are based on the arrangement of the first air duct 2 in the cavity 10 between the inner sheet metal 11 and the outer sheet metal 12. Unless otherwise specified, the cavity 10 referred to below refers to the cavity between the inner sheet metal 11 and the outer sheet metal 12.
[0058] Regarding the material selection of the first air duct 2. In one example, the material of the first air duct 2 can be metal. For example, the material of the first air duct 2 can be bake hardening (BH) steel, high-strength low-alloy steel (HSLA) steel, dual-phase (DP) steel, quenching and partitioning (QP) steel, or 6 series aluminum alloy.
[0059] Among them, BH steel has strong strength. HSLA steel is a type of steel that achieves the required strength level by adding small amounts of alloying elements (such as niobium, vanadium, titanium, copper, nickel, chromium, and phosphorus). It has high strength and good mechanical properties while maintaining good weldability and formability. 6 series aluminum alloys are a type of aluminum alloy composed of elements such as aluminum, magnesium, and silicon, and have excellent mechanical properties, corrosion resistance, and machinability.
[0060] Therefore, the material of the first air duct 2 is selected from the BH steel, HSLA steel, or 6 series aluminum alloy mentioned above. The first air duct 2 is equivalent to a metal reinforcement tube, making the first air duct 2 a structural component, thereby significantly improving the performance parameters such as the strength and stiffness of the entire vehicle.
[0061] As an example, if the first air duct 2 is used as a structural component, its material can be selected from 340 high-strength alloy galvanized steel (abbreviated as HC340LAD+Z), 420 high-strength alloy galvanized steel (abbreviated as HC420LAD+Z), DP590, DP780, DP980, QP980, S600 aluminum alloy and 6111 aluminum alloy.
[0062] In one example, the first air duct 2 may be made of metal, but is not used as a structural component. In this case, the first air duct 2 may be made of die-cast (DC) steel, mild steel, or 5-series aluminum alloy. For example, the first air duct 2 may be made of mild steel, DC steel, 5754 aluminum alloy, or 5182 aluminum alloy.
[0063] In another example, the material of the first air duct 2 may also be plastic, such as polyethylene (PE) and polypropylene (PP).
[0064] The present embodiment does not limit the specific material of the first air duct 2 and can be flexibly selected according to needs.
[0065] In one example, as described above, the first beam 1 generally structurally includes not only an inner sheet metal part 11 and an outer sheet metal part 12, but also, as shown in FIG1 , a side outer panel 13, wherein the outer sheet metal part 12 generally serves as a structural part to enhance the strength and rigidity of the beam.
[0066] If the strength and rigidity of the first air duct 2 are relatively large, equivalent to a metal reinforcement tube, and can be used as a structural component, then, as shown in FIG3 , the side outer panel 13 and the outer sheet metal component 12 of the first vehicle beam 1 can be combined into one and integrated together. It can be understood that the side outer panel 13 is omitted, and the outer sheet metal component 12 serves as the side outer panel.
[0067] In one example, in which the side outer panel 13 and the outer sheet metal component 12 are integrated, as shown in FIG3 , the cross-sectional area of the first air duct 2 can be relatively large, thereby fully utilizing the first air duct 2 as a structural component. For example, the cross-sectional area of the first air duct 2 is greater than or equal to half the cross-sectional area of the chamber 10, and less than the cross-sectional area of the chamber 10. The large cross-sectional area of the first air duct 2 allows the first air duct 2 to function as a relatively thick metal reinforcement tube.
[0068] It should be pointed out that the cross-sectional area of the cavity 10 of the first beam 1 may not be equal everywhere along the length direction. Therefore, the cross-sectional area of the first air duct 2 may not be equal everywhere along the length direction. In this case, at any cross-section, the cross-sectional area of the first air duct 2 is greater than or equal to half of the cross-sectional area of the cavity 10 and less than the cross-sectional area of the cavity 10.
[0069] In this way, since the cross-sectional area of the first air duct 2 is relatively large, the strength and rigidity of the first air duct 2 will also be relatively large, thereby being able to significantly enhance the strength and rigidity of the entire vehicle body.
[0070] Of course, in the scenario where the first air duct 2 serves as a structural component, the first beam 1 can also include both the inner sheet metal 11 and outer sheet metal 12, as well as the side outer panels 13. In this way, the first air duct 2, the inner sheet metal 11, the outer sheet metal 12, and the side outer panels 13 all serve as structural components, enhancing the strength and rigidity of the entire vehicle. In other words, as shown in Figure 2, the material of the first air duct 2 can also be a structural component with relatively high strength and rigidity, effectively acting as a metal reinforcement tube.
[0071] The above is an introduction to the material of the first air duct 2 . The following will introduce a method for fixing the first air duct 2 in the chamber 10 .
[0072] In one example, the first air duct 2 can be directly fixed to the cavity 10 of the first beam 1. For example, the outer surface of the first air duct 2 is fixed to the inner wall of the cavity 10 by gluing, wherein the glue used is a high-temperature resistant structural adhesive to prevent cracking. In another example, the outer surface of the first air duct 2 is fixed to the inner wall of the cavity 10 by welding.
[0073] In another example, the first air duct 2 can also be indirectly fixed in the cavity 10 of the first beam 1 through a bracket. For example, as shown in FIG2 , the first air duct 2 is mounted on the inner wall of the cavity 10 through a bracket 4 .
[0074] As an example, referring to FIG2 , the bracket 4 is an integrated bracket, with a first end of the bracket 4 fixed to the first inner wall of the chamber 10, and a second end of the bracket 4 extending along the circumference of the first air duct 2, bypassing the first air duct 2, and fixed to the first inner wall of the chamber 10. In other words, the integrated bracket 4 is clamped on the first air duct 2.
[0075] In the solution where the first air duct 2 is fixed to the inner wall of the chamber 10 through an integrated bracket 4 , there may be no fixed relationship between the bracket 4 and the first air duct 2 , but there is a fixed relationship between the bracket 4 and the inner wall of the chamber 10 .
[0076] For example, as shown in Figure 2, when the first air duct 2 is fixed on the chamber 10 through the integrated bracket 4, the first end of the bracket 4 can be first fixed at position ① of the first inner wall of the chamber 10, and then the second end of the bracket 4 can be passed around the first air duct 2 and fixed at position ② of the first inner wall of the chamber 10.
[0077] Of course, the first air duct 2 and the inner wall of the chamber 10 may also be fixed to each other, and the bracket 4 and the chamber 10 may also be fixed to each other. Continuing with FIG2 , the first air duct 2 and the first inner wall of the chamber 10 may first be fixed at position ③, which may be done by welding or gluing. The two ends of the bracket 4 may then be fixed at positions ① and ②, respectively, as shown in FIG2 .
[0078] In one example, the bracket 4 and the inner wall of the chamber 10 may be fixed by gluing, welding, riveting, or screwing. The adhesive used in the gluing method may be a high-temperature resistant structural adhesive, the welding method may be spot welding, arc welding, or laser welding, and the riveting method may be self-piercing rivets (SPR), flow drill screws (FDS), or core-pulling rivets.
[0079] In another example, the bracket 4 can also be a split bracket, as shown in Figure 4, the bracket 4 includes a first bracket 41 and a second bracket 42, wherein the first end of the first bracket 41 is fixed at the first position of the first air duct 2, and the second end of the first bracket 41 is fixed on the first inner wall of the chamber 10, and the first end of the second bracket 42 is fixed at the second position of the first air duct 2, and the second end of the second bracket 42 is fixed on the first inner wall of the chamber 10, wherein the first position and the second position of the first air duct 2 are located at different positions of the first air duct 2.
[0080] For example, the first position and the second position of the first air duct 2 are respectively located on two opposite sides of the first air duct 2 .
[0081] The first bracket 41 and the first air duct 2 may be fixed by gluing or welding, and the first bracket 41 and the inner wall of the chamber 10 may be fixed by gluing, welding, riveting, or screwing. Similarly, the second bracket 42 and the first air duct 2 may be fixed by gluing or welding, and the second bracket 42 and the inner wall of the chamber 10 may be fixed by gluing, welding, riveting, or screwing.
[0082] The bracket and the first air duct are not riveted or screwed together because riveting or screwing requires drilling holes in the first air duct, which may cause air leakage in the first air duct.
[0083] In one example, in a scheme where the first air duct 2 is fixed to the inner wall of the chamber 10 through a split bracket 4, there may be no fixed relationship or a fixed relationship between the first air duct 2 and the inner wall of the chamber 10. In the scheme where there is a fixed relationship, the first air duct 2 and the inner wall of the chamber 10 may be glued or welded.
[0084] In one example, since the first air duct 2 has a certain length, no matter whether the bracket 4 is an integrated type or a split type, there are multiple brackets 4 , and the multiple brackets 4 are arranged at intervals along the length direction of the first air duct 2 .
[0085] In one example, the number of brackets 4 can be determined according to the length of the first air duct 2. For example, a bracket 4 can be arranged every 100 to 200 mm along the length direction of the first air duct 2, wherein the arranged brackets 4 can be an integrated bracket, a split bracket, or both an integrated bracket and a split bracket.
[0086] It should be noted that this embodiment does not specifically limit whether the first air duct 2 is directly fixed to the inner wall of the chamber 10 or fixed to the inner wall of the chamber 10 via the bracket 4. In the scheme where the first air duct 2 is fixed to the inner wall of the chamber 10 via the bracket 4, whether it is fixed to the inner wall of the chamber 10 via an integrated bracket or a split bracket is also not specifically limited.
[0087] However, in the solution where the first air duct 2 is fixed to the inner wall of the chamber 10 through an integrated bracket 4, since there is no fixed relationship between the first air duct 2 and the bracket 4, as well as between the first air duct 2 and the inner wall of the chamber 10, the first air duct 2 can be installed in the chamber 10 without damage, and then the first air duct 2 will not leak air.
[0088] In the solution where the first air duct 2 is fixed to the inner wall of the chamber 10 by a split bracket 4, the split bracket uses less material compared to the integrated bracket, which is not only beneficial for saving materials but also for reducing the weight of the car.
[0089] In one example, to reduce vibration and noise caused by the installation of the first air duct 2, the cavity 10 where the first air duct 2 is located can be filled with a foam material. Referring to FIG5 , in a solution where the first beam includes an inner sheet metal component 11, an outer sheet metal component 12, and a side outer panel 13, the space between the outer wall of the first air duct 2 and the inner wall of the cavity 10 is filled with a foam material. The line drawn between the outer wall of the first air duct 2 and the inner wall of the cavity 10 in FIG5 represents the foam material. Of course, the cavity between the outer sheet metal component 12 and the side outer panel 13 can also be filled with foam material.
[0090] Referring to Figure 6, in the solution where the first vehicle beam includes an inner sheet metal part 11 and an outer sheet metal part 12, a foam material is filled between the outer wall of the first air duct 2 and the inner wall of the chamber 10. The line filling between the outer wall of the first air duct 2 and the inner wall of the chamber 10 in Figure 6 represents the foam material.
[0091] The main component of the foaming material can be polyurethane, isocyanate, or polyether polyol. Alternatively, the foaming material can include two main components: one main component is isocyanate and its prepolymer, and the other main component is a curing agent. The specific composition of the foaming material is not limited in this embodiment; it is sufficient to provide noise and vibration reduction and fixation.
[0092] In one example, a fluid foaming material can be injected between the first air duct 2 and the chamber 10 through an injection process. The fluid foaming material solidifies after foaming and fills the space between the outer wall of the first air duct 2 and the inner wall of the chamber 10 .
[0093] The foam material filled between the outer wall of the first air duct 2 and the inner wall of the chamber 10 not only fixes the first air duct 2 but also absorbs noise and reduces vibration.
[0094] In this way, the foam material is filled between the outer wall of the first air duct 2 and the inner wall of the chamber 10 , which can improve the noise, vibration, harshness (NVH) performance of the entire vehicle.
[0095] In one example, the solution in which the first air duct 2 is arranged in the cavity 10 of the first vehicle beam 1 can be applied to a car including one vehicle air conditioner or a car including two vehicle air conditioners.
[0096] For example, a vehicle air conditioner includes a first vehicle air conditioner and a second vehicle air conditioner, the first vehicle air conditioner being installed in the engine compartment of the vehicle and the second vehicle air conditioner being installed in the trunk of the vehicle, and the first air duct 2 being connected to the second vehicle air conditioner. In this solution, as shown in FIG7 , the vehicle includes a front pillar, a rear pillar, and a pillar top rail connecting the front pillar and the rear pillar. Therefore, the first vehicle beam 1 specifically includes the pillar top rail and the rear pillar.
[0097] The front pillar is the A-pillar of the car, and the rear pillar is the pillar near the trunk, such as the C-pillar or D-pillar. For cars with a C-pillar as the rear pillar, the pillar upper side rail is the upper side rail located above the B-pillar. For cars with a D-pillar as the rear pillar, the pillar upper side rail is the upper side rail located above the B-pillar and C-pillar.
[0098] 7 and 8 are schematic diagrams of a car, FIG7 is a schematic side view of the car, and FIG8 is a schematic top view of the car.
[0099] The following example uses a car with two air conditioners. One of these air conditioners is designated as the first air conditioner and serves as the primary air conditioner, installed in the engine compartment. The other is designated as the second air conditioner and serves as the secondary air conditioner, installed in the trunk, such as on the right side of the trunk. The car is illustrated as having three pillars: the A-pillar, the B-pillar, and the C-pillar. For example, the first air outlet is positioned between the B-pillar and the C-pillar. Figure 8 only illustrates the approximate location of the second air conditioner, not the location of the first air conditioner. The black dot in Figure 8 indicates the location of the first air outlet, and the dotted line indicates the first air duct.
[0100] As shown in Figure 8, on the right side of the vehicle, a first air duct connecting the second onboard air conditioner on the right side to the first air outlet on the right side has its first end connected to the second onboard air conditioner, and its second end first enters the cavity of the right C-pillar, then enters the cavity of the right B-pillar top rail, and then connects to the first air outlet on the right side. Therefore, on the right side of the vehicle, both the C-pillar and the B-pillar top rail are part of the first vehicle beam 1.
[0101] Continuing with FIG8 , on the left side of the vehicle body, a first air duct is used to connect the second onboard air conditioner on the right side with the first air outlet on the left side. The first end is connected to the second onboard air conditioner, and the second end first enters the cavity of the rear crossbeam, then enters the cavity of the left B-pillar upper side beam, and then connects to the first air outlet on the left side. Therefore, on the left side of the vehicle body, the rear crossbeam and the B-pillar upper side beam both belong to the first vehicle beam 1. Of course, if the first air duct also passes through the cavity of the C-pillar, then the C-pillar also belongs to the first vehicle beam 1. The rear crossbeam is located on the roof and is close to the trunk (not shown in FIG8 ).
[0102] Of course, the first air duct 2 may not pass through the cavity of the rear cross beam and be connected to the first air outlet on the left. For example, the first air duct 2 may be first arranged on the clothes rack in the trunk (such as fixed above or below the clothes rack), and then the first air duct 2 enters the cavity of the left C-pillar and the cavity of the left B-pillar upper side beam in turn, and then connects to the first air outlet on the left.
[0103] Among them, in this embodiment, there is no specific limitation on which columns, upper side beams, and cross beams the first vehicle beam 1 specifically includes. In actual application, it is related to the specific position of the first air outlet and the layout position of the second vehicle air conditioner.
[0104] In the embodiment of the present disclosure, the air duct of the automobile can be installed in the cavity of the vehicle beam during layout. For example, the first air duct in the air duct can be installed in the cavity of the first vehicle beam in the vehicle beam. In this way, the first air duct is hidden in the cavity formed by the two sheet metal parts of the first vehicle beam, which not only realizes the hiding of the air duct, but also reduces the space occupied by the air duct in the vehicle, thereby alleviating the problem of insufficient space for the arrangement of the air duct in the automobile.
