Description

Technical Field

[0001] The present disclosure relates to the technical field of automotive ventilation, and particularly to an automobile. Background Art

[0002] In a whole vehicle, an air conditioning system generally includes an air conditioner, an air duct, an air outlet, etc. The air duct and the air outlet are responsible for delivering the processed air flow (such as temperature processing, humidity processing, purification processing, etc.) to the passenger compartment of the vehicle to complete functions such as ventilation, refrigeration, heating, defrosting, demisting, and air purification in the passenger compartment.

[0003] However, as people's requirements for vehicle performance, functions, and human-machine are getting higher and higher, the number of components integrated in the whole vehicle is also increasing, resulting in a shortage of space for the current air duct layout. Summary of the Invention

[0004] The present disclosure provides an automobile, in which the air duct of the automobile can be arranged in the chamber of the 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 shortage of space existing in the air duct layout in the automobile.

[0005] The present disclosure provides an automobile, which includes an in-vehicle air conditioner, an air duct, an air outlet, and a vehicle beam. The vehicle beam has a chamber along the length direction;

[0006] The vehicle beam includes a first vehicle beam, the air duct includes a first air duct, the first air duct is installed in the chamber of the first vehicle beam and is communicated with the in-vehicle air conditioner, the air outlet includes a first air outlet, and the first air outlet is located inside the vehicle and is communicated with the first air duct.

[0007] Among them, the vehicle beam, as the framework of the automobile, includes columns, cross beams, longitudinal beams, etc. These vehicle beams all have chambers along the length direction. Therefore, the air duct can be installed in the chamber of the vehicle beam. Then, the vehicle beam in which the air duct is installed can be denoted as the first vehicle beam.

[0008] Among them, the air duct connecting the in-vehicle air conditioner and the air outlet can be arranged in the chamber of the vehicle beam or at other positions. Then, the air duct arranged in the chamber of the vehicle beam is denoted as the first air duct.

[0009] Among them, there are many air outlets in the automobile. Then, the air outlet communicated with the first air duct is denoted as the first air outlet.

[0010] In the solution shown in the present disclosure, the first air duct is installed in the chamber of the first vehicle beam, and the chamber of the vehicle beam does not belong to the interior space of the vehicle. Then, such an arrangement of the first air duct not only realizes the hiding of the first air duct but also reduces the space occupied by the air duct in the vehicle, thereby alleviating the shortage of space existing in the air duct layout.

[0011] In a possible implementation, the first vehicle beam includes an inner sheet metal part and an outer sheet metal part, and the chamber is formed between the inner sheet metal part and the outer sheet metal part.

[0012] In the solution shown in the present disclosure, the first air duct is arranged in the chamber formed between the inner sheet metal part and the outer sheet metal part of the first vehicle beam, rather than between the inner sheet metal part and the interior trim panel. The space between the inner sheet metal part and the outer sheet metal part does not belong to the interior space of the vehicle, while the space between the inner sheet metal part and the interior trim panel belongs to the interior space of the vehicle. Therefore, arranging the first air duct in this way can reduce the occupied space of the air duct in the vehicle.

[0013] In a possible implementation, the first air duct is installed on the inner wall of the chamber through a bracket.

[0014] In the solution shown in the present disclosure, the first air duct can be directly fixed on the inner wall of the chamber. However, installing the first air duct on the inner wall of the chamber through a bracket can achieve a lossless installation of the first air duct and avoid air leakage of the first air duct.

[0015] In a possible implementation, the first end of the bracket is fixed on the first inner wall of the chamber, and the second end bypasses the first air duct along the circumferential direction of the first air duct and is fixed on the first inner wall of the chamber.

[0016] In the solution shown in the present disclosure, the bracket can be an integral bracket. The first end of the bracket can be first fixed on the first inner wall of the chamber, and then the other end bypasses the first air duct and is fixed on the first inner wall of the chamber. In this way, the integral bracket clamps the first air duct on the first inner wall of the chamber. In this solution for fixing the first air duct through the integral bracket, only the two ends of the bracket need to be fixed to the same inner wall of the chamber. There is no fixed relationship between the first air duct and the chamber, and there is also no fixed relationship between the first air duct and the bracket. In this way, a lossless installation of the first air duct can be achieved, and air leakage of the first air duct can be avoided.

[0017] In a possible implementation, the bracket includes a first bracket and a second bracket. The first end of the first bracket is fixed at a first position of the first air duct, and the second end is fixed on the first inner wall of the chamber. The first end of the second bracket is fixed at a second position of the first air duct, and the second end is fixed on the first inner wall of the chamber, where the first position and the second position of the first air duct are at different positions of the first air duct.

[0018] In the solution shown in the present disclosure, the bracket can be a split bracket, including a first bracket and a second bracket. The first air duct is fixed to the inner wall of the chamber by these two brackets. Compared with an integral bracket, the split bracket uses less material, which is beneficial for saving materials and reducing weight.

[0019] In a possible implementation, the number of the brackets is multiple, and the multiple brackets are arranged at intervals along the length direction of the first air duct.

[0020] In the solution shown in the present disclosure, since the first air duct has a certain length, multiple 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.

[0021] In a possible implementation, a foaming material is filled between the inner wall of the chamber and the outer wall of the first air duct.

[0022] In the solution shown in the present disclosure, filling the foaming material between the inner wall of the chamber and the outer wall of the first air duct can, on the one hand, firmly fix the first air duct in the chamber through the foaming material, and on the other hand, the filled foaming material can absorb the noise and vibration generated by the first air duct. Therefore, the filled foaming material has the effects of fixing, noise reduction and vibration reduction.

[0023] In a possible implementation, the cross-sectional area of the first air duct is greater than or equal to half of the cross-sectional area of the chamber and less than the cross-sectional area of the chamber.

[0024] In the solution shown in the present disclosure, the cross-sectional area of the first air duct is relatively large, which enables the first air duct to be used as a strengthening pipe to improve the strength and stiffness of the vehicle. For example, if the material of the first air duct is metal, when its cross-sectional area is relatively large, the first air duct can be used as a strengthening pipe, and thus the first air duct serves both as an air duct and as a structural member.

[0025] In a possible implementation, the material of the first air duct is metal or plastic.

[0026] In the solution shown in the present disclosure, the material of the first air duct is metal, especially a metal material with relatively high stiffness and strength, which enables the first air duct to be used as a structural member.

[0027] In a possible implementation, the vehicle-mounted air conditioner includes a first vehicle-mounted air conditioner and a second vehicle-mounted air conditioner. The first vehicle-mounted air conditioner is installed in the engine compartment of the vehicle, and the second vehicle-mounted air conditioner is installed in the trunk of the vehicle. The first air duct is communicated with the second vehicle-mounted air conditioner.

[0028] In the solution shown in the present disclosure, the vehicle includes two on-vehicle air conditioners. One is installed in the engine compartment to provide a comfortable in-vehicle environment for the occupants in the driver's cab and the front passenger's cab, and the other is installed in the trunk to provide a relatively comfortable in-vehicle environment for the rear passengers.

[0029] In a possible implementation manner, the vehicle includes a front pillar, a rear pillar, and an upper side beam of the pillar connecting the front pillar and the rear pillar. The first vehicle beam includes the upper side beam of the pillar and the rear pillar.

[0030] In the solution shown in the present disclosure, the first air duct can pass through the chamber of the rear pillar and extend into the chamber of the upper side beam of the pillar, and then communicate with the first air outlet.

[0031] In the solution shown in the present disclosure, the front pillar is the A-pillar of the vehicle, 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 chamber of the C-pillar and extend into the chamber of the upper side beam of the pillar.

[0032] In the solution shown in the present disclosure, the front pillar is the A-pillar of the vehicle, 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 chamber of the D-pillar and extend into the chamber of the upper side beam of the pillar. Description of the Drawings

[0044] To make the objectives, technical solutions, and advantages of the present disclosure clearer, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0045] This embodiment relates to an automobile, specifically to the air conditioning system of the automobile. The air conditioning system of the automobile mainly includes an on-vehicle air conditioner, an air duct, and an air outlet. Among them, the on-vehicle air conditioner is generally arranged in the engine compartment, and the air outlets generally include a front air outlet and a rear air outlet. Among them, the front air outlet is usually arranged in the middle of the center console and at the positions near the windows on both sides, and the rear air outlet is generally arranged at the rear side of the storage box between the driver's seat and the front passenger seat, and the air duct is used to connect the on-vehicle air conditioner and each air outlet. For example, the air duct between the on-vehicle air conditioner and the rear air outlet at the rear side of the storage box is arranged in the middle channel of the automobile.

[0046] Among them, the air conditioning system of the automobile is used to realize the air circulation inside the vehicle and the temperature control inside the vehicle, and provide a comfortable interior environment for the driver and passengers. However, for large automobiles, such as automobiles with a wheelbase greater than 3 meters, or D-class automobiles, the rear space is relatively large. It is difficult to achieve a comfortable level by only relying on the rear air outlet at the rear side of the storage box to provide the interior environment for the passengers in the rear row.

[0047] For this reason, some large automobiles will install an additional on-vehicle air conditioner. In this way, the automobile includes two on-vehicle air conditioners, which are respectively denoted as the first on-vehicle air conditioner and the second on-vehicle air conditioner. Among them, the first on-vehicle air conditioner is used as the main on-vehicle air conditioner and is still arranged in the engine compartment, and the second on-vehicle air conditioner is used as the auxiliary on-vehicle air conditioner and is arranged at the rear side of the automobile.

[0048] Among them, the air ducts and air outlets connected to the first on-vehicle air conditioner generally follow the previous arrangements. As described above, the front air outlet is arranged in the middle of the center console and at the positions near the windows on both sides, the rear air outlet is arranged at the rear side of the storage box, and the air duct connected to the rear air outlet is arranged in the middle channel. And the air duct connected to the second on-vehicle air conditioner is generally arranged on the outer surface of the inner sheet metal part of the body-in-white. Then, an interior trim part is wrapped on the outer surface of the inner sheet metal part to hide the air duct fixed on the inner sheet metal part. The air outlet connected to the second on-vehicle air conditioner faces the interior of the vehicle and is located in the rear space.

[0049] However, the air duct connected to the second vehicle-mounted air conditioner is arranged on the outer surface of the inner sheet metal part, which will occupy the interior space of the whole vehicle, is not conducive to improving the integration degree of the whole vehicle, and moreover, occupying the interior space of the whole vehicle will make the rear space of the whole vehicle relatively crowded, and to a certain extent, will reduce the riding comfort of the rear passengers.

[0050] For this reason, this embodiment provides a vehicle. The air duct of this vehicle can be arranged in the chamber of the vehicle beam, which not only hides the air duct, does not affect the appearance, but also does not occupy the interior space of the vehicle, and has a high integration degree.

[0051] The vehicle includes a vehicle-mounted air conditioner, an air duct, an air outlet and a vehicle beam. Among them, the air duct is connected to the air outlet of the vehicle-mounted air conditioner, and the air outlet is connected to the air duct. In this way, the vehicle-mounted air conditioner can convey appropriate air flow to the air outlet through the air duct.

[0052] Among them, the vehicle beam includes the columns of the vehicle (such as A-pillar, B-pillar, C-pillar and D-pillar), the upper side beam located on the side of the vehicle, and the cross beam located on the top of the vehicle, etc.

[0053] Such as Figure 1 shown, is a cross-sectional schematic diagram of the vehicle beam. Referring to Figure 1 shown, the first vehicle beam 1 includes an inner sheet metal part 11, an outer sheet metal part 12 and an outer side panel 13. Among them, a chamber 10 is formed between the inner sheet metal part 11 and the outer sheet metal part 12, and a chamber is also formed between the outer sheet metal part 12 and the outer side panel 13.

[0054] Then, the air duct connecting the vehicle-mounted air conditioner and the air outlet can be installed in the chamber of the vehicle beam. In this way, not only the air duct is hidden, does not affect the appearance, but also does not occupy the interior space of the vehicle, and the integration degree is high.

[0055] In one example, air ducts are not installed in all the chambers of the vehicle beam, nor are all air ducts installed in the chambers of the vehicle beam (of course, all air ducts can also be installed in the chambers of the vehicle beam). Therefore, the vehicle beam can include the first vehicle beam 1, and the air duct can include the first air duct 2. Among them, the first vehicle beam 1 is one or some vehicle beams in the vehicle beam whose chambers are installed with air ducts, and the first air duct 2 is a certain section of the air duct installed in the chamber of the vehicle beam.

[0056] Similarly, not all air outlets are connected to the first air duct 2. The air outlets connected to the first air duct 2 can be recorded as the first air outlets, and the first air outlets are arranged facing the interior of the vehicle.

[0057] In one example, the first air duct 2 is connected to the vehicle-mounted air conditioner. The first end of the first air duct 2 can be directly connected to the air outlet of the vehicle-mounted air conditioner, or the first end of the first air duct 2 can be indirectly connected to the air outlet of the vehicle-mounted air conditioner through other air ducts. Similarly, the first air duct 2 is connected to the first air outlet. 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 other air ducts.

[0058] In one example, the first air duct 2 is installed in the chamber 10 of the first vehicle beam 1. It can be installed in the chamber 10 between the inner sheet metal part 11 and the outer sheet metal part 12, or it can be installed in the chamber between the outer panel 13 of the side wall and the outer sheet metal part 12. This embodiment does not limit this. In actual installation, a chamber with a relatively large cross-sectional area is selected to install the first air duct. Usually, the cross-sectional area of the chamber between the inner sheet metal part 11 and the outer sheet metal part 12 of the first vehicle beam 1 is relatively large. Therefore, in the following, examples are given with the first air duct 2 arranged in the chamber 10 between the inner sheet metal part 11 and the outer sheet metal part 12. Unless otherwise specified, the chamber 10 mentioned below is the chamber between the inner sheet metal part 11 and the outer sheet metal part 12.

[0059] 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 baking hardening (BH) steel or high-strength low-alloy steel (HSLA) or dual-phase steel (DP) or quenching and partitioning (QP) steel or 6-series aluminum alloy, etc.

[0060] Among them, BH steel has relatively high strength. HSLA steel is a kind of steel that obtains the required strength level by adding a small amount 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 alloy is a kind of aluminum alloy composed of elements such as aluminum, magnesium, and silicon, and has excellent mechanical properties, corrosion resistance, and workability.

[0061] Therefore, the material of the first air duct 2 is selected as the above-mentioned BH steel or HSLA steel or 6-series aluminum alloy, etc. The first air duct 2 is equivalent to a metal reinforcing pipe, making the first air duct 2 a structural member, and thus can greatly improve performance parameters such as the strength and stiffness of the whole vehicle.

[0062] In one example, if the first air duct 2 is used as a structural member, its material can be selected from materials such as 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.

[0063] In one example, the material of the first air duct 2 can be metal, but it is not used as a structural member. Then, its material can be die casting (DC) steel series, mild steel, or 5-series aluminum alloy. For example, its material can be selected from mild steel, DC steel, 5754 aluminum alloy, and 5182 aluminum alloy, etc.

[0064] In another example, the material of the first air duct 2 can also be plastic, such as materials like polyethylene (PE) and polypropylene (PP).

[0065] Among them, the specific material of the first air duct 2 in this embodiment is not limited and can be flexibly selected according to requirements.

[0066] In one example, as described above, the first vehicle beam 1 generally includes not only an inner sheet metal part 11 and an outer sheet metal part 12 in terms of structure. Refer to Figure 1 As shown, the first vehicle beam 1 also includes an outer side panel 13. Among them, the outer sheet metal part 12 is generally used as a structural member to enhance the strength and stiffness of the vehicle beam.

[0067] If the strength and stiffness of the first air duct 2 are relatively large, equivalent to a metal reinforcement tube and capable of being used as a structural member, then, as Figure 3 shown, the outer side panel 13 and the outer sheet metal part 12 of the first vehicle beam 1 can be combined into one and integrated together. It can be understood that the outer side panel 13 is omitted, and the outer sheet metal part 12 serves as the outer side panel.

[0068] In one example, in the scheme where the outer side panel 13 and the outer sheet metal part 12 are integrated together, refer to Figure 3 As shown, the cross-sectional area of the first air duct 2 can be relatively large, so that the role of the first air duct 2 as a structural member can be fully exerted. For example, the cross-sectional area of the first air duct 2 is greater than or equal to half of the cross-sectional area of the chamber 10 and less than the cross-sectional area of the chamber 10. The relatively large cross-sectional area of the first air duct 2 makes the first air duct 2 a relatively thick metal reinforcement tube.

[0069] It should be noted that the cross-sectional area of the chamber 10 of the first vehicle beam 1 may not be equal everywhere along the length direction. Similarly, the cross-sectional area of the first air duct 2 may also 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 satisfies being greater than or equal to half of the cross-sectional area of the chamber 10 and less than the cross-sectional area of the chamber 10.

[0070] In this way, due to the relatively large cross-sectional area of the first air duct 2, the strength and stiffness of the first air duct 2 will also be relatively large, which can significantly enhance the strength and stiffness of the entire vehicle body.

[0071] Of course, in the solution where the first air duct 2 is used as a structural member, the first vehicle beam 1 can also include both the inner sheet metal part 11 and the outer sheet metal part 12, as well as the outer side panel 13. In this way, the first air duct 2, the inner sheet metal part 11, the outer sheet metal part 12, and the outer side panel 13 all serve as structural members to improve the strength and stiffness of the entire vehicle. That is, as Figure 2 shown, the material of the first air duct 2 can also be a structural member with relatively high strength and stiffness, and the first air duct 2 is equivalent to a metal reinforcing pipe.

[0072] The above is the introduction about the material of the first air duct 2. Next, the fixing method of the first air duct 2 in the chamber 10 will be introduced.

[0073] In one example, the first air duct 2 can be directly fixed in the chamber 10 of the first vehicle beam 1. For example, the outer surface of the first air duct 2 is fixed on the inner wall of the chamber 10 by an adhesive method, and the adhesive used is a high-temperature resistant structural adhesive to avoid cracking. Another example is that the outer surface of the first air duct 2 is fixed on the inner wall of the chamber 10 by a welding method.

[0074] In another example, the first air duct 2 can also be indirectly fixed in the chamber 10 of the first vehicle beam 1 through a bracket. For example, as Figure 2 shown, the first air duct 2 is installed on the inner wall of the chamber 10 through a bracket 4.

[0075] As an example, referring to Figure 2 shown, the bracket 4 is an integral bracket. The first end of the bracket 4 is fixed on the first inner wall of the chamber 10, and the second end of the bracket 4 bypasses the first air duct 2 along the circumferential direction of the first air duct 2 and is fixed on the first inner wall of the chamber 10. That is, the integral bracket 4 is clamped on the first air duct 2.

[0076] Among them, in the solution where the first air duct 2 is fixed on the inner wall of the chamber 10 through the integral bracket 4, there may be no fixed relationship between the bracket 4 and the first air duct 2, while there is a fixed relationship between the bracket 4 and the inner wall of the chamber 10.

[0077] For example, as Figure 2 shown, during the process of fixing the first air duct 1 to the chamber 10 through the integral bracket 4, the first end of the bracket 4 can be first fixed at position ① on the first inner wall of the chamber 10, and then the second end of the bracket 4 can be bypassed around the first air duct 2 and fixed at position ② on the first inner wall of the chamber 10.

[0078] Of course, it can also be that there is a fixing relationship between the first air duct 1 and the inner wall of the chamber 10, and there is also a fixing relationship between the bracket 4 and the chamber 10. Continuing to refer to Figure 2 shown, the first air duct 1 and the first inner wall of the chamber 10 can be first fixed at position ③, and the fixing method can be welding or gluing. Then, the two ends of the bracket 4 can be respectively fixed at the positions as Figure 2 shown at position ① and position ②.

[0079] In one example, the fixing method between the bracket 4 and the inner wall of the chamber 10 can be gluing, welding, riveting or screwing. Among them, the glue used in the gluing method can be a high-temperature resistant structural glue, and the specific welding method adopted in the welding method can be spot welding, arc welding or laser welding, etc. Riveting can be self-piercing rivet (SPR), flow drill screw (FDS) connection, or blind riveting, etc.

[0080] In another example, the bracket 4 can also be a split bracket, as Figure 4 shown, the bracket 4 includes a first bracket 41 and a second bracket 42. Among them, the first end of the first bracket 41 is fixed at the first position of the first air duct 2, 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. Among them, the first position and the second position of the first air duct 2 are located at different positions of the first air duct 2.

[0081] For example, the first position and the second position of the first air duct 2 are respectively located on opposite sides of the first air duct 2.

[0082] Among them, the fixing method between the first bracket 41 and the first air duct 2 can be gluing or welding, and the fixing method between the first bracket 41 and the inner wall of the chamber 10 can be gluing, welding, riveting or screwing, etc. Similarly, the fixing method between the second bracket 42 and the first air duct 2 can be gluing or welding, and the fixing method between the second bracket 42 and the inner wall of the chamber 10 can be gluing, welding, riveting or screwing, etc.

[0083] Among them, riveting or screwing is not adopted between the bracket and the first air duct because riveting and screwing require drilling holes in the first air duct, and drilling holes will cause air leakage in the first air duct.

[0084] In one example, in the solution 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. Among them, in the solution with a fixed relationship, gluing or welding can be adopted between the first air duct 2 and the inner wall of the chamber 10.

[0085] In one example, since the first air duct 2 has a certain length, therefore, regardless of whether the bracket 4 is integral or split, the number of brackets 4 is multiple, and the multiple brackets 4 are arranged at intervals along the length direction of the first air duct 2.

[0086] In one example, the number of brackets 4 can be determined according to the length of the first air duct 2. For example, one bracket 4 can be arranged every about 100 to 200 millimeters along the length direction of the first air duct 2. Among them, the arranged brackets 4 can be integral brackets, split brackets, or brackets that include both integral brackets and split brackets.

[0087] 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 through the bracket 4. In the solution where the first air duct 2 is fixed to the inner wall of the chamber 10 through the bracket 4, it is not specifically limited whether it is fixed to the inner wall of the chamber 10 through an integral bracket or a split bracket.

[0088] However, in the solution where the first air duct 2 is fixed to the inner wall of the chamber 10 through an integral bracket 4, since there may be 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 is installed in the chamber 10 without damage. Then, there will be no air leakage phenomenon in the first air duct 2.

[0089] In the solution where the first air duct 2 is fixed to the inner wall of the chamber 10 through a split bracket 4, compared with the integral bracket, the split bracket uses less material. Then, it is not only beneficial to save materials but also beneficial to reduce the weight of the vehicle.

[0090] In one example, in order to reduce the vibration and noise caused by installing the first air duct 2, correspondingly, the chamber 10 where the first air duct 2 is located can be filled with foaming material. Refer to Figure 5As shown, in the solution where the first vehicle beam includes an inner sheet metal part 11, an outer sheet metal part 12, and an outer side panel 13, foaming material is filled between the outer wall of the first air duct 2 and the inner wall of the chamber 10. Of course, foaming material can also be filled in the chamber between the outer sheet metal part 12 and the outer side panel 13. Figure 5 The gray filling in

[0091] is the foaming material. Figure 6 As shown in the reference Figure 6 in the solution where the first vehicle beam includes an inner sheet metal part 11 and an outer sheet metal part 12, foaming material is filled between the outer wall of the first air duct 2 and the inner wall of the chamber 10.

[0092] Among them, the main components of the foaming material can be polyurethane, or isocyanate, or polyether polyol. Or, the components of the foaming material can also include two main components. One main component is isocyanate and its prepolymer, and the other main component is a curing agent. Here, the specific components of the foaming material in this embodiment are not limited, as long as it can play a role in noise reduction, vibration reduction, and fixation.

[0093] In one example, the flowable foaming material can be injected between the first air duct 2 and the chamber 10 through an injection process. The flowable foaming material is cured after foaming and filled between the outer wall of the first air duct 2 and the inner wall of the chamber 10.

[0094] The foaming material filled between the outer wall of the first air duct 2 and the inner wall of the chamber 10 plays a role in fixing the first air duct 2 on the one hand, and on the other hand, plays a role in absorbing noise and can also play a role in vibration reduction.

[0095] In this way, filling foaming material between the outer wall of the first air duct 2 and the inner wall of the chamber 10 can improve the noise, vibration, and harshness (NVH) performance of the whole vehicle.

[0096] In one example, the solution where the first air duct 2 is arranged in the chamber 10 of the first vehicle beam 1 can be applied to a vehicle including one on-vehicle air conditioner, or can also be applied to a vehicle including two on-vehicle air conditioners.

[0097] For example, the on-vehicle air conditioner includes a first on-vehicle air conditioner and a second on-vehicle air conditioner. The first on-vehicle air conditioner is installed in the engine compartment of the vehicle, and the second on-vehicle air conditioner is installed in the trunk of the vehicle. The first air duct 2 is communicated with the second on-vehicle air conditioner. In this solution, as Figure 7 shown, the vehicle includes a front pillar, a rear pillar, and an upper pillar side beam connecting the front pillar and the rear pillar. Then, the first vehicle beam 1 can specifically include the upper pillar side beam and the rear pillar.

[0098] Among them, the front pillar is the A-pillar of the vehicle, and the rear pillar is the pillar near the trunk, such as it can be the C-pillar or the D-pillar. For a vehicle with the rear pillar being the C-pillar, the upper side beam of the pillar is the upper side beam located above the B-pillar. For a vehicle with the rear pillar being the D-pillar, the upper side beam of the pillar is the upper side beam located above the B-pillar and the C-pillar.

[0099] Such as Figure 7 and 8 The schematic diagram of the vehicle is shown as Figure 7 It is the side view schematic diagram of the vehicle, Figure 8 It is the top view schematic diagram of the vehicle.

[0100] Taking a vehicle including two vehicle-mounted air conditioners as an example, one of the two vehicle-mounted air conditioners is denoted as the first vehicle-mounted air conditioner and serves as the main vehicle-mounted air conditioner, which is installed in the engine compartment. The other is denoted as the second vehicle-mounted air conditioner and serves as the auxiliary vehicle-mounted air conditioner, which is installed in the trunk, such as on the right side of the trunk. This vehicle is exemplified by including three pillars: the A-pillar, the B-pillar, and the C-pillar. Taking the first air outlet being arranged between the B-pillar and the C-pillar as an example. Figure 8 Only the approximate position of the second vehicle-mounted air conditioner is schematically shown in Figure 8 The black dot in

[0101] Refer to Figure 8 As shown, on the right side of the vehicle body, for the first air duct connecting the second vehicle-mounted air conditioner on the right side to the first air outlet on the right side, the first end is communicated with the second vehicle-mounted air conditioner, the second end first enters the chamber of the C-pillar on the right side, then enters the chamber of the upper side beam of the B-pillar on the right side, and then is communicated with the first air outlet on the right side. Then, on the right side of the vehicle body, both the C-pillar and the upper side beam of the B-pillar belong to the first vehicle beam 1.

[0102] Continue to refer to Figure 8 As shown, on the left side of the vehicle body, for the first air duct connecting the second vehicle-mounted air conditioner on the right side to the first air outlet on the left side, the first end is communicated with the second vehicle-mounted air conditioner, the second end first enters the chamber of the rear crossbeam, then enters the chamber of the upper side beam of the B-pillar on the left side, and then is communicated with the first air outlet on the left side. Then, on the left side of the vehicle body, both the rear crossbeam and the upper side beam of the B-pillar belong to the first vehicle beam 1. Of course, if the first air duct also passes through the chamber of the C-pillar, then the C-pillar also belongs to the first vehicle beam 1. Among them, the rear crossbeam is located on the roof and is close to the trunk ( Figure 8 not shown in

[0103] Of course, the first air duct 2 may also not pass through the chamber of the rear crossbeam and be connected to the first air outlet on the left side. For example, the first air duct 2 may be first arranged on the clothes hanger in the trunk (such as fixed above or below the clothes hanger), and then the first air duct 2 enters the chamber of the left C-pillar and the chamber of the upper side beam of the left B-pillar in sequence, and then is communicated with the first air outlet on the left side.

[0104] Wherein, in this embodiment, there is no specific limitation on which columns, which upper side beams, and which crossbeams the first vehicle beam 1 specifically includes. In actual application, it is related to the specific position of the first air outlet and also related to the arrangement position of the second vehicle-mounted air conditioner.

[0105] In the embodiment of the present disclosure, during the arrangement of the air ducts of the vehicle, they can be installed in the chambers of the vehicle beams. For example, the first air duct in the air ducts can be installed in the chamber of the first vehicle beam in the vehicle beam. In this way, the first air duct is hidden in the chamber formed by the two sheet metal parts of the first vehicle beam, which not only realizes the hiding of the air duct but also can reduce the space occupied by the air duct in the vehicle, thereby alleviating the situation of insufficient space existing in the air duct arrangement in the vehicle.
