Description

Technical Field

[0001] This application relates to the field of vehicle air conditioning design technology, and in particular to a vehicle air conditioning system and vehicle. Background Technology

[0002] With economic growth and improved living standards, people have higher demands for comfort when traveling by vehicle. Temperature comfort is a crucial aspect of overall comfort and is receiving increasing attention. Therefore, current technology typically equips vehicles with onboard air conditioning.

[0003] Air conditioning provides cool air to the vehicle's passenger compartment during hot summer days, thus cooling the interior. Conversely, it provides warm air to the passenger compartment during cold winter days, thus warming the interior.

[0004] However, temperature comfort is not limited to simply providing cool or warm air. More and more passengers are concerned about the evenness of cool or warm air distribution throughout the vehicle's passenger space. Uneven distribution of cool air can cause some areas of the passenger space (near the air conditioner) to feel cold due to excessive cooling, while other areas (away from the air conditioner) may feel uncomfortably warm due to insufficient cooling. Similarly, uneven distribution of warm air can cause some areas of the passenger space (near the air conditioner) to feel hot due to excessive heating, while other areas (away from the air conditioner) may feel uncomfortably warm due to insufficient heating.

[0005] Therefore, it is evident that vehicles equipped with air conditioning cannot meet passengers' requirements for temperature comfort. To address this, existing vehicles incorporate air ducts to direct the cold or warm air from the air conditioning vents to areas further away from the air conditioner. However, this has proven insufficient. Therefore, the applicant of this invention, after analyzing the vehicle structure in existing technologies, discovered that due to the inherent structural limitations of vehicles, in-vehicle air conditioners cannot be installed in the exact center of the vehicle. This results in existing vehicles having air conditioners positioned too far forward or too far back. This arrangement causes excessive cold or warm air to be directed to either the front or rear of the passenger space, resulting in insufficient airflow to the other. Ultimately, this leads to an uneven distribution of cold or warm air towards the front and rear of the vehicle, disrupting the balance of comfort and limiting improvements in temperature comfort. Utility Model Content

[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0053] For ease of description, spatial relative terms may be used in this text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptions used in this text will be interpreted accordingly.

[0054] To address the problem that existing vehicles cannot adequately balance passenger comfort, this application provides an in-vehicle air conditioning system. The provided in-vehicle air conditioning system is applied in a vehicle.

[0055] Please refer to Figures 1-8 The vehicle involved includes the vehicle body 10, which is the main structure of the vehicle. The vehicle body 10 is equipped with a passenger space 11, a fixed air duct 12, and other essential vehicle structures such as doors and windows.

[0056] The fixed air duct 12 is connected to the passenger space 11, and its two ends extend towards the front and rear of the vehicle body 10, respectively. That is, one end of the fixed air duct 12 extends towards the front of the vehicle body 10, and the other end extends towards the rear of the vehicle body 10. The fixed air duct 12 has air outlets 131 distributed along its extension direction. During its extension, the fixed air duct 12 discharges the cold or warm air generated by the vehicle's air conditioning system into the passenger space 11 through the air outlets 131.

[0057] It should be noted that the front of the vehicle body 10 is the front of the vehicle, and the rear of the vehicle body 10 is the rear of the vehicle.

[0058] The vehicle air conditioning system provided in this application embodiment includes an air conditioner 20 and an auxiliary air duct 30. The air conditioner 20 and the auxiliary air duct 30 can be directly or indirectly installed on the vehicle body 10.

[0059] The air conditioner 20 is the main body of the vehicle's air conditioning system. It generates cold or warm air to regulate the temperature of the passenger space 11. For driving safety, the air conditioner 20 is fixed to the vehicle body 10. Specifically, the air conditioner 20 can be installed on the top wall of the vehicle body 10, thus outputting cold or warm air downwards from above the passenger space 11.

[0060] It should be noted that in the vehicle involved in this application embodiment, the distance between the air conditioner 20 and either the front or rear of the vehicle is smaller than the distance between it and the other. In other words, the air conditioner 20 is not located in the middle of the vehicle body 10. In one embodiment, the air conditioner 20 is positioned close to the front of the vehicle, such that the distance between the air conditioner 20 and the front of the vehicle body 10 is smaller than the distance between the air conditioner 20 and the rear of the vehicle body 10. In another embodiment, the air conditioner 20 is positioned close to the rear of the vehicle, such that the distance between the air conditioner 20 and the front of the vehicle body 10 is greater than the distance between the air conditioner 20 and the rear of the vehicle body 10.

[0061] In this embodiment, the air conditioner 20 is provided with multiple air conditioning outlets 21, through which the cold or warm air generated by the air conditioner 20 during operation flows out. In this embodiment, the multiple air conditioning outlets 21 are located in and connected to the fixed air duct 12. Since the two ends of the fixed air duct 12 extend towards the front and rear of the vehicle, respectively, and the fixed air duct 12 has air duct outlets 131 distributed along its extension direction, the cold or warm air entering the fixed air duct 12 from the air conditioning outlets 21 will be transported to the front and rear of the vehicle. At the same time, the transported cold or warm air will also be transported to the corresponding area in the passenger space 11 through the air duct outlets 131.

[0062] The first end of the auxiliary air guide duct 30 is connected to a portion of the multiple air conditioning outlets 21. For example, the first end of the auxiliary air guide duct 30 can be connected to one of the multiple air conditioning outlets 21. Optionally, the first end of the auxiliary air guide duct 30 can be sealed to the air conditioning outlet 21 it is connected to. The second end of the auxiliary air guide duct 30 extends towards the front or rear of the vehicle where the distance between the air conditioning outlets 20 is greater, thereby guiding cold or warm air separately to the front or rear of the vehicle where the distance is greater, ultimately achieving the purpose of supplementing the front or rear of the vehicle with cold or warm air.

[0063] It should be noted that, in this embodiment, the auxiliary air duct 30 connects to a portion of the multiple air conditioning outlets 21, enabling all the cold or warm air output from these outlets to be directed to the front or rear of the vehicle, which is farther from the air conditioning unit 20. This compensates for the lack of sufficient cold or warm air at the front or rear of the vehicle, thus addressing the issue of uneven comfort caused by insufficient cold or warm air at these locations. The cold or warm air flowing from the air conditioning outlets 21 connected to the auxiliary air duct 30 will not be directed to the front or rear of the vehicle, which is closer to the air conditioning unit 20.

[0064] The vehicle air conditioning system provided in this application embodiment, during the process of the air conditioner 20 transmitting cold or warm air to the front and rear of the vehicle through the fixed air duct 12, further improves the comfort balance within the passenger space 11 by adding an auxiliary air guide duct 30 and connecting the auxiliary air guide duct 30 to a portion of the air conditioning outlet 21 of the air conditioner 20. This allows a portion of the cold or warm air produced by the air conditioner 20 to be delivered to the front or rear of the vehicle, which is farther from the air conditioner 20, thereby supplementing the cold or warm air in these areas. This avoids the problem of insufficient temperature regulation in these areas far from the air conditioner 20 due to insufficient cold or warm air, and ultimately improves the comfort balance within the passenger space 11.

[0065] In this embodiment, the auxiliary air duct 30 can have various structures. For example, the auxiliary air duct 30 can be an integral structure, such as a single, continuous pipe. For ease of connection, in another embodiment, the auxiliary air duct 30 may include a connector 31 and a main body pipe 32. The connector 31 may have an air inlet 311 and an air outlet 312, with the orientation of the air inlet 311 and the air outlet 312 intersecting; in other words, the central axis of the air inlet 311 intersects the central axis of the air outlet 312. The air inlet 311 is used to connect with a portion of the multiple air conditioning outlets 21. The air outlet 312 connects to the first port of the main body pipe 32, and the second port of the main body pipe 32 extends towards the front or rear of the vehicle, which is at a greater distance from the air conditioner 20.

[0066] Since the air conditioning vent 21 is located on the top wall 101 of the vehicle body 10, and the fixed air duct 12 extends roughly along the length of the vehicle, and the fixed air duct 12 and the auxiliary air duct 30 are located below the top wall 101, the connector 31 in the above structure is designed to be able to be turned and connected. Thus, by designing the connector 31, the auxiliary air duct 30 can be more easily connected to the air conditioning vent 21.

[0067] In this embodiment, the structure of the connector 31 can be varied, as long as it facilitates easy turning and connection. In one specific embodiment, the inner wall of the connector 31 opposite to the air inlet 311 can be an arc-shaped inner wall, which can smoothly connect the air inlet 311 and the main body pipe 32. In this structure, the arc-shaped inner wall can smoothly guide the cold or warm air entering the air inlet 311 from the air conditioner outlet 21, thereby reducing the obstruction of the cold or warm air by the inner wall of the connector 31. This allows the cold or warm air to enter the main body pipe 32 as quickly as possible after entering the connector 31 with less obstruction. Therefore, this type of connector 31 is beneficial for the rapid transmission of cold or warm air.

[0068] To facilitate connection, the auxiliary air duct 30 provided in this embodiment may further include a connecting plate 34. The connecting plate 34 can be fixed to the top of the vehicle body 10. The connecting plate 34 is provided with a clearance hole 341. The connector 31 can be fixed to the top of the vehicle body 10 by welding, bonding, or connecting with connectors, while simultaneously allowing the air inlet 311 to align with the clearance hole 341. The connecting plate 34 can also be a reinforcing plate. The connecting plate 34 can be fixed to the top wall 101 by threaded connectors, thereby forming a solid foundation and providing conditions for the subsequent installation of the connector 31. The connector 31 can also be fixed to the connecting plate 34 by threaded connectors. It should be noted that this embodiment does not limit the specific fixing methods between the connector 31 and the connecting plate 34, or between the connecting plate 34 and the top wall 101.

[0069] As described above, the orientation of the air inlet 311 and the air outlet 312 intersect. To avoid obstructing the flow of cold or warm air, in one embodiment, the orientation of the air inlet 311 and the air outlet 312 can be greater than or equal to 90°. Specifically, the orientation of the air inlet 311 and the air outlet 312 can be perpendicular. The orientation of the air conditioner outlet 21 can be perpendicular to the extension direction of the main body pipe 32. This structure is more suitable for the positional relationship between the top wall 101 and the main body pipe 32.

[0070] In this embodiment, the first port of the main body tube 32 is fixedly connected to the air outlet 312. Specifically, the first port of the main body tube 32 and the air outlet 312 can be sealed together. To facilitate connection, the first end of the main body tube 32 with the first port can be inserted into the air outlet 312 for connection, or the end of the connector 31 with the air outlet 312 can be inserted into the first port of the main body tube 32 for connection. To improve the stability of the connection, the first end of the main body tube 32 with the air outlet 312 and the first end of the main body tube 32 can be further fixedly connected by fastening screws, thereby improving the stability of the connection between them.

[0071] In one embodiment, the auxiliary air duct 30 may be a non-extendable structure. Considering that different types of vehicles or vehicles of the same type but different sizes all need to be equipped with the vehicle air conditioning system disclosed in this application embodiment, in another embodiment, the main tube 32 may be a telescopic tube, which can change its length by telescoping, thereby adapting to vehicles of different sizes. Specifically, the second port of the main tube 32 may move relative to the first port of the main tube 32 along the air delivery direction of the fixed air duct 12 to achieve telescoping of the main tube 32. Specifically, the main tube 32 may be made of a telescoping elastic material.

[0072] In other embodiments, the main tube 32 can be designed as a telescopic structure to achieve telescopic extension. This application does not limit the telescopic structure of the main tube 32. For example, in one embodiment, the main tube 32 is a corrugated pipe that can be extended by folding. In another embodiment, the main tube 32 may include a fixed section 321 and a movable section 322, with the first port of the fixed section 321 fixedly connected to the air outlet 312. It should be noted that the first port of the fixed section 321 is the same as the first port of the main tube 32 mentioned above. The movable section 322 is lined within the fixed section 321. The fixed section 321 can slide with the movable section 322 to achieve telescopic extension of the main tube 32. The telescopic extension of the main tube 32 essentially enables the length of the auxiliary air duct 30 to be adjustable, thereby allowing the auxiliary air duct 30 to meet the needs of vehicles of different sizes. Meanwhile, in this structure, the movable pipe section 322 is lined inside the fixed pipe section 321 and slides relative to the fixed pipe section 321. The radial dimension of the movable pipe section 322 is smaller than the radial dimension of the fixed pipe section 321.

[0073] Furthermore, the movable pipe segment 322 can also be fitted outside the fixed pipe segment 321, and the fixed pipe segment 321 can slide with the movable pipe segment 322. Compared to the movable pipe segment 322 slidingly lining the fixed pipe segment 321, the movable pipe segment 322, when fitted outside the fixed pipe segment 321, has a larger radial dimension than the fixed pipe segment 321. In embodiments where the movable pipe segment 322 and the fixed pipe segment 321 are of the same material and length, a larger radial dimension of the movable pipe segment 322 means a heavier movable pipe segment 322. In some installation environments, the second end of the main pipe 32 is not supported. In this case, the main pipe 32 can essentially be a cantilever structure connected to the connector 31. Therefore, fitting the movable pipe segment 322 outside the fixed pipe segment 321 will increase the torque. Thus, it is evident that lining the movable pipe segment 322 inside the fixed pipe segment 321 helps reduce the torque, thereby contributing to the stability of the air duct 30 structure.

[0074] In the structure of the auxiliary air duct 30, the number of movable pipe segments 322 can be one or multiple; the embodiments of this application do not limit the number of movable pipe segments 322. Similarly, the embodiments of this application do not limit the length of the movable pipe segments 322. In one embodiment, there is one movable pipe segment 322. If a large range of extension and retraction is required, the fixed pipe segment 321 and the movable pipe segment 322 can be designed to be longer, thereby achieving a larger range of extension and retraction with fewer pipe segments. In this case, the operator does not need to assemble multiple movable pipe segments 322, thus simplifying the assembly process. Considering that the auxiliary air duct 30 can more flexibly adapt to various vehicle models, in other embodiments, there can be multiple movable pipe segments 322. If a large range of extension and retraction is required, multiple movable pipe segments 322 are sequentially lined inside the fixed pipe segment 321 or sequentially sleeved outside the fixed pipe segment 321. The fixed pipe segment 321 slides with the adjacent movable pipe segment 322, and two adjacent movable pipe segments 322 slide with each other. In this structure, the main tube 32 can be extended and retracted over a large range by sliding more tube segments. At the same time, since there are more tube segments, it is not necessary to design each tube segment (fixed tube segment 321 and movable tube segment 322) to be longer. This makes it easier for the overall size of the main tube 32 to be smaller after shrinkage, so that it can be installed in smaller vehicles.

[0075] The connector 31, fixed pipe section 321, and movable pipe section 322 can be made of non-metallic materials, such as plastic or rubber, thereby reducing the weight of the auxiliary air duct 30 and facilitating its installation within the vehicle body 10. In other embodiments, the connector 31, fixed pipe section 321, and movable pipe section 322 can be made of metallic materials, such as iron or aluminum. This application does not limit the specific materials of the components included in the auxiliary air duct 30.

[0076] In this embodiment, the movable tube segment 322 and the fixed tube segment 321 are in a sliding fit. Specifically, there can be significant friction between the movable tube segment 322 and the fixed tube segment 321, allowing them to remain relatively stationary after the movable tube segment 322 extends from or retracts from the fixed tube segment 321, thus maintaining the main tube 32 at the adjusted length. Similarly, in embodiments where there are multiple movable tube segments 322, adjacent movable tube segments 322 are in a sliding fit. Specifically, there can be significant friction between adjacent movable tube segments 322, allowing them to remain relatively stationary after one movable tube segment 322 extends from or retracts from the other, thus maintaining the main tube 32 at the adjusted length.

[0077] It should be noted that there are various ways to maintain the fixed pipe segment 321 and the adjacent movable pipe segment 322 relatively stationary, and to maintain the relative stationary state of two adjacent movable pipe segments 322, not limited to the frictional force between them. In other embodiments, the auxiliary air guide duct 30 may include a locking assembly 33. When the locking assembly 33 is in the locked state, the fixed pipe segment 321 and the adjacent movable pipe segment 322 are fixedly connected by the locking assembly 33. When the locking assembly 33 is in the unlocked state, the fixed pipe segment 321 and the adjacent movable pipe segment 322 are slidably engaged. When the locking assembly 33 is in the locked state, the locking assembly 33 can perform a fixing function, thereby fixing the fixed pipe segment 321 and the adjacent movable pipe segment 322. In one embodiment, the locking assembly 33 may be at least one locking screw. The locking screw achieves a fixed connection between the two by engaging with the connection holes on the fixed pipe segment 321 and the movable pipe segment 322. In this embodiment, the locking component 33 can improve the stability of the fixed pipe section 321 and the movable pipe section 322, thereby avoiding the problem of changes in the length of the auxiliary air duct 30 due to shaking and vibration during vehicle operation.

[0078] In another embodiment, the locking component 33 can be a clamping structure, such as a clamping structure. For example, in an embodiment where the fixed pipe segment 321 is fitted outside the adjacent movable pipe segment 322, the locking component 33 can clamp the fixed pipe segment 321, thereby causing the fixed pipe segment 321 to deform and thus clamp the movable pipe segment 322, ultimately achieving a fixed connection between the movable pipe segment 322 and the fixed pipe segment 321. In this case, the movable pipe segment 322 adjacent to the fixed pipe segment 321 cannot move relative to the fixed pipe segment 321, ultimately achieving a relative stationary state between the two.

[0079] This application provides a locking assembly 33 with a specific structure. Specifically, the locking assembly 33 includes a clamping member 331, a bolt 332, and a nut 333.

[0080] The clamping member 331 wraps around the fixed pipe section 321, and both ends of the clamping member 331 are opposite each other and each has a connecting hole 3311. When the locking assembly 33 is in the locked state, the bolt 332 passes through the connecting hole 3311 and is tightened by the nut 333 to connect the two ends of the clamping member 331, thereby driving the fixed pipe section 321 to clamp the movable pipe section 322. When the locking assembly 33 is in the unlocked state, the nut 333 is loosened to drive the fixed pipe section 321 to release the movable pipe section 322, thereby allowing the movable pipe section 322 to extend from or retract into the fixed pipe section 321.

[0081] During the specific locking operation, the operator passes the bolt 332 through the connecting holes 3311 on both ends of the clamping member 331, and then screws on the nut 333 until it is tightened. In this case, the two ends of the clamping member 331 are fixedly connected by the bolt 332 and the nut 333. During the process of the two ends of the clamping member 331 being fixedly connected, they move closer to each other to clamp the fixed pipe section 321. After the fixed pipe section 321 is clamped, it can further clamp the movable pipe section 322 inside it by its own deformation, and finally achieve the fixed connection between the fixed pipe section 321 and the movable pipe section 322, so as to maintain the relative stillness of the two. During the unlocking process, the operator can loosen nut 333 or remove it after loosening, thereby releasing the fixed connection at both ends of clamping member 331. Clamping member 331 then deforms, causing its two ends to move away from each other, ultimately releasing the clamping member 331 from the fixed pipe section 321. The fixed pipe section 321 can then deform and release its grip on the movable pipe section 322. In this case, the movable pipe section 322 can slide relative to the fixed pipe section 321. In this structure, the all-round wrapping of clamping member 331 better enables the fixed pipe section 321 to clamp the movable pipe section 322 through deformation, thereby improving the fixation stability of the movable pipe section 322.

[0082] As described above regarding the locking and unlocking processes, the locking component 33 essentially locks the movable pipe section 322 by deforming the fixed pipe section 321, thereby fixing the fixed pipe section 321 and the movable pipe section 322 together. Therefore, designing the fixed pipe section 321 to be easily deformable facilitates the locking operation. Based on this, in one embodiment, the fixed pipe section 321 can be a thin-walled pipe structure. In other embodiments, the wall of the fixed pipe section 321 can have a strip-shaped notch 3211, which can extend to the first port of the fixed pipe section 321. During the actual locking process, as the clamping member 331 clamps, the two edges of the strip-shaped notch 3211 will move closer together, making it easier to deform the fixed pipe section 321. This structure essentially removes a local area of ​​the fixed pipe section 321, thereby reducing the strength of the fixed pipe section 321 without affecting its function, thus providing better conditions for subsequent deformation under the clamping action of the clamping member 331.

[0083] Of course, in other embodiments, the material of the fixed pipe segment 321 can be changed to a material that is easily deformable and has a certain strength. For example, the fixed pipe segment 321 can be made of rubber. Alternatively, in some other embodiments, the sidewalls of the fixed pipe segment 321 forming the port are locally thin-walled after thinning treatment, so that it can be more easily clamped and deformed when the locking component 33 is in the locked state, and thus more easily clamp the movable pipe segment 322 through deformation.

[0084] As described above, when there are multiple movable pipe segments 322, adjacent movable pipe segments 322 slide and nest together. The friction between adjacent movable pipe segments 322 is used to keep them relatively stationary. This structure does not require a locking assembly 30, and has the advantage of structural simplicity. It has also been explained above that the fixed pipe segment 321 and the adjacent movable pipe segment 322 can be fixed together by the locking assembly 33, and relative sliding is achieved when the locking assembly 33 is in the unlocked state.

[0085] Similarly, in embodiments where there are multiple movable pipe segments 322, adjacent movable pipe segments 322 can also be fixedly connected by locking components 33. Specifically, when the locking components 33 are in the locked state, the outer movable pipe segment 322 of the two adjacent movable pipe segments 322 is clamped and deformed by the locking components 33, further clamping the inner movable pipe segment 322, ultimately achieving fixation between the two adjacent movable pipe segments 322. When the locking components 33 are in the unlocked state, the clamping fixation between the outer and inner movable pipe segments 322 is released, allowing them to slide relative to each other, thereby realizing the extension and retraction of the main pipe 32 and achieving the purpose of adjusting the length of the main pipe 32.

[0086] It should be noted that, in this article, the movable pipe segment 322 located on the outer side refers to the movable pipe segment 322 with the larger radial dimension among two adjacent and nested movable pipe segments 322. In this article, the movable pipe segment 322 located on the inner side refers to the movable pipe segment 322 with the smaller radial dimension among two adjacent and nested movable pipe segments 322.

[0087] In embodiments where the locking assembly 33 includes a clamping member 331, a bolt 332, and a nut 333, when the locking assembly 33 is in the unlocked state, the operator can detach the locking assembly 33. In this case, it is easier for the two adjacent movable pipe sections 322 to slide during contraction. Without affecting the movement of the movable pipe section 322, the middle portion of the clamping member 331 of the locking assembly 33 can be fixed to the outer wall of the fixed pipe section 321 by means of fastening screws, adhesive, or other methods.

[0088] In this embodiment, the movement of the movable pipe segment 322 can change the length of the main pipe 32, thereby adjusting the length of the entire auxiliary air guide duct 30 and making the auxiliary air guide duct 30 more flexible and adaptable. During operation, a size marking 3221 can be provided on the outer wall of the movable pipe segment 322. The size marking 3221 can display the length of the auxiliary air guide duct 30 after the movable pipe segment 322 has moved, making it easier for operators to control the extension degree of the movable pipe segment 322.

[0089] The size marking 3221 can be of various types. For example, the size marking 3221 can be a number representing the length of the auxiliary air duct 30, a letter representing the length of the auxiliary air duct 30, or a size scale line representing the length of the auxiliary air duct 30. This application embodiment does not limit the specific type of the size marking 3221. Of course, in other embodiments, to improve the marking effect, the size marking 3221 can include at least two of the following: a number representing the length of the auxiliary air duct 30, a letter representing the length of the auxiliary air duct 30, and a size scale line representing the length of the auxiliary air duct 30.

[0090] In this embodiment, the shapes of the fixed pipe section 321 and the movable pipe section 322 can be adapted to each other, and the shapes of two adjacent movable pipe sections 322 can be adapted to each other, thereby improving their compactness after assembly and preventing leakage of cold or warm air during the process of guiding cold or warm air by the auxiliary air guide duct 30. For example, in one embodiment, both the fixed pipe section 321 and the movable pipe section 322 can be rectangular pipes, circular pipes, or elliptical pipes. This embodiment does not limit the specific shape of the fixed pipe section 321 and the movable pipe section 322. Similarly, the shape of the connector 31 can be adapted to the shape of the main pipe 32. For example, the air outlet 312 of the connector 31 can be a rectangular opening, and the main pipe 32 can be a rectangular pipe. As another example, the air outlet 312 of the connector 31 can be a circular opening, and the main pipe 32 can be a circular pipe.

[0091] Based on the vehicle air conditioning system provided in the embodiments of this application, this application further provides a vehicle. The provided vehicle includes a vehicle body 10 and the vehicle air conditioning system provided in the above embodiments.

[0092] The vehicle body 10 includes a passenger space 11 and a fixed air duct 12 connected to the passenger space 11. The two ends of the fixed air duct 12 extend toward the front and rear of the vehicle body 10, respectively.

[0093] The air conditioner 20 is located on the top wall 101 of the vehicle body 10. The air conditioner 20 has multiple air conditioning vents 21, which are located in and connected to the fixed air duct 12. The distance between the air conditioner 20 and either the front or rear of the vehicle is smaller than the distance between the air conditioner 20 and the other.

[0094] The first end of the auxiliary air duct 30 is connected to a portion of the multiple air conditioning outlets 21. The second end of the auxiliary air duct 30 extends toward the front or rear of the vehicle, where the distance between it and the air conditioning unit 20 is relatively large.

[0095] To improve the efficiency of delivering cold or warm air, in one embodiment, fixed air ducts 12 are provided on both sides of the top wall 101 of the vehicle body 10. Air conditioning vents 21 are arranged in two rows, each row including multiple air conditioning vents 21. At least one of the two fixed air ducts 12 may be equipped with an auxiliary air guide duct 30, which connects to a portion of the air conditioning vents 21 located within the same fixed air duct 12. In this case, a portion of the air conditioning vents 21 located within the same fixed air duct 12 can connect to the auxiliary air guide duct 30, extending through the auxiliary air guide duct 30 to the front or rear of the vehicle, where the distance to the air conditioner 20 is smaller. The other portion of the air conditioning vents 21 located within the same fixed air duct 12 directly outputs cold or warm air into the fixed air duct 12.

[0096] In this structure, fixed air ducts 12 can be set on both sides of the top of the vehicle body 10, thereby improving the efficiency of cold or warm air transmission to the front and rear of the vehicle body 10.

[0097] In other embodiments, the air conditioning vents 21 may be arranged in more rows, with each row of air conditioning vents 21 including multiple air conditioning vents 21. Both fixed air ducts 12 are connected to at least one row of air conditioning vents 21. Of course, in order to consider the uniformity of cold or warm air transmission, the number of rows of air conditioning vents 21 connected in the two fixed air ducts 12 is equal. For example, in the two fixed air ducts 12, each fixed air duct 12 is connected to two rows of air conditioning vents 21.

[0098] In this application embodiment, the structure of the fixed air duct 12 can be various, and this application embodiment is not limited. In one embodiment, the fixed air duct 12 can be a metal pipe fixed inside the vehicle body 10.

[0099] In another embodiment, the vehicle body 10 has a top wall 101 and two opposing side walls 102. The top wall 101 forms corners with each of the two opposing side walls 102 of the vehicle body 10. The vehicle body 10 also includes a support plate 13, which is provided at the corner. The support plate 13 and the corner form a fixed air duct 12. The support plate 13 has air outlets 131 distributed along the extension direction of the fixed air duct 12. This structure allows the support plate 13 to be fixed at the top of the passenger space 11, so that the support plate 13 and the corner form a fixed air duct 12. This makes full use of the existing structure in the vehicle body 10 and simply adds the support plate 13 to form a fixed air duct 12. This is beneficial for making full use of the corner to form a fixed air duct 12 with a larger space, while not consuming too much material.

[0100] Meanwhile, the support plate 13 not only forms a fixed air duct 12 with the corner, but also functions as a reinforcing plate, strengthening the local structure of the vehicle body 10. To improve the strengthening effect, the support plate 13 in this embodiment can be a high-strength metal plate, such as steel plate or iron plate.

[0101] To improve the uniformity of cold or warm air delivery in the fixed air duct 12, the air outlets 131 can be designed with a preset distribution pattern. For example, the air outlets 131 can be evenly distributed along the extension direction of the fixed air duct 12. Alternatively, the air outlets 131 can have equal apertures, and become increasingly dense in the direction away from the air conditioner 20 to compensate for insufficient airflow.

[0102] The vehicles disclosed in this application embodiment can be tour buses, ordinary buses, train carriages, subway carriages, etc. This application embodiment does not limit the specific type of vehicle.
