Description

Technical Field

[0001] The present application relates to the technical field of vehicle air conditioning design, and in particular to a vehicle air conditioning system and a vehicle. Background Art

[0002] With economic growth and improved quality of life, people are placing higher demands on vehicle comfort. Thermal comfort is a crucial component of this comfort and is attracting increasing attention. To address this, vehicles are typically equipped with onboard air conditioners.

[0003] Air conditioners can provide cool air to the vehicle's passenger space in the hot summer, thereby achieving the purpose of cooling the vehicle's passenger space. At the same time, air conditioners can also provide warm air to the vehicle's passenger space in the cold winter, thereby achieving the purpose of heating the vehicle's passenger space.

[0004] However, thermal comfort is not limited to simply providing cold or warm air. More and more passengers are concerned about the uniformity of cold or warm air in the vehicle's passenger space. Uneven distribution of cold air can cause some local areas of the vehicle's passenger space (areas close to the air conditioner) to feel cold due to excessive cold air, while other local areas (areas away from the air conditioner) feel uncomfortable due to insufficient cold air. Similarly, uneven distribution of warm air can cause some local areas of the vehicle's passenger space (areas close to the air conditioner) to feel hot due to excessive warm air, while other local areas (areas away from the air conditioner) feel uncomfortable due to insufficient warm air.

[0005] It can be seen that vehicles equipped with air conditioners cannot meet the passengers' requirements for temperature comfort. For this reason, vehicles in the prior art are equipped with air ducts, which are used to transport the cold or warm air output from the air-conditioning outlet of the air conditioner to an area far away from the air conditioner. However, it has been proven that this still does not achieve the best results. For this reason, the inventors of the present invention analyzed the vehicle structure in the prior art and found that due to the structural limitations of the vehicle itself, the vehicle-mounted air conditioner cannot be installed in the middle of the vehicle. This results in the air conditioner in the prior art being arranged too far forward or too far back. This arrangement will cause the cold or warm air from the air conditioner to be excessively transported to one of the front and rear parts of the vehicle's passenger space, resulting in insufficient air volume in the other part. Ultimately, the cold or warm air cannot be evenly transported toward the front and rear of the vehicle, which makes it impossible to reconcile the comfort balance and ultimately restricts the improvement of temperature comfort.

[0051] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0052] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0053] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside", "outside", "inside", "outside", "below", "beneath", "above", "above", "front", "back", etc. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a position flip or a change in posture or a change in motion state, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will then be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device can be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptions used herein should be interpreted accordingly.

[0054] In order to solve the problem that vehicles in the prior art cannot well meet the balance of passenger comfort, an embodiment of the present application provides a vehicle air conditioning system. The provided vehicle air conditioning system is applied to a vehicle.

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

[0056] The fixed air duct 12 is connected to the passenger space 11, with its ends extending toward the front and rear of the vehicle body 10, respectively. In other words, one end of the fixed air duct 12 extends toward the front of the vehicle body 10. The other end of the fixed air duct 12 extends toward the rear of the vehicle body 10. The fixed air duct 12 is provided with air duct outlets 131 distributed along its extension direction. As the fixed air duct 12 extends, it discharges the cold or warm air generated by the vehicle's air conditioning system into the passenger space 11 through the air duct 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 the embodiment of the present application 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 component of the vehicle's air conditioning system. It is used to generate cool or warm air to regulate the temperature of the passenger space 11. To ensure 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, thereby outputting cool or warm air downward from above the passenger space 11.

[0060] It should be noted that in the embodiments of the present application, the distance between the air conditioner 20 and one of the front and rear ends of the vehicle is smaller than the distance between the air conditioner 20 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 located near the front end of the vehicle body 10, so that the distance between the air conditioner 20 and the front end of the vehicle body 10 is smaller than the distance between the air conditioner 20 and the rear end of the vehicle body 10. In another embodiment, the air conditioner 20 is located near the rear end of the vehicle body 10, so that the distance between the air conditioner 20 and the front end of the vehicle body 10 is larger than the distance between the air conditioner 20 and the rear end of the vehicle body 10.

[0061] In the embodiment of the present application, the air conditioner 20 is provided with a plurality of air conditioning outlets 21, and the cold air or warm air generated by the air conditioner 20 during operation flows out through the plurality of air conditioning outlets 21. In the embodiment of the present application, the plurality of air conditioning outlets 21 are located in the fixed air duct 12 and are connected to the fixed air duct 12. Since the two ends of the fixed air duct 12 extend in the direction close to the front and the rear of the vehicle, respectively, and the fixed air duct 12 is provided with air duct outlets 131 distributed along its extension direction, the cold air or warm air entering the fixed air duct 12 from the air conditioning outlets 21 will be transported to the front and the rear of the vehicle. At the same time, the transported cold air 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 duct 30 interfaces with some of the plurality of air conditioning outlets 21. For example, the first end of the auxiliary air duct 30 may interface with one of the plurality of air conditioning outlets 21. Alternatively, the first end of the auxiliary air duct 30 may be sealedly interfaced with the corresponding air conditioning outlet 21. The second end of the auxiliary air duct 30 extends toward the front or rear of the vehicle, where the distance between the air conditioning units 20 is greater. This allows the auxiliary air duct 30 to direct cool or warm air toward the further front or rear, ultimately providing additional cool or warm air to the further front or rear.

[0063] It should be noted that in the embodiment of the present application, the auxiliary air duct 30 interfaces with some of the multiple air conditioning outlets 21, allowing the cold or warm air output from these air conditioning outlets 21 to be directed entirely to the front or rear of the vehicle, which is farther from the air conditioning 20. This compensates for the lack of cold or warm air at these locations, resulting in a lack of comfort. The cold or warm air flowing from the air conditioning outlets 21 interfaced with the auxiliary air duct 30 will not be directed to the front or rear of the vehicle, which is closer to the air conditioning 20.

[0064] The vehicle air-conditioning system provided in the embodiment of the present application, during the process of the air conditioner 20 transmitting cold air or warm air to the front and rear of the vehicle through the fixed air duct 12, further adds an auxiliary air duct 30, and connects the auxiliary air duct 30 with a part of the air-conditioning outlet 21 of the air conditioner 20, and then transmits a part of the cold air or warm air produced by the air conditioner 20 to the front or rear of the vehicle farther away from the air conditioner 20 through the auxiliary air duct 30, thereby supplementing the cold air or warm air for the front or rear of the vehicle farther away from the air conditioner 20, thereby avoiding the problem of insufficient temperature regulation due to insufficient cold air or warm air in these areas farther away from the air conditioner 20, and ultimately improving the comfort balance in the riding space 11.

[0065] In an embodiment of the present application, the auxiliary air duct 30 may have a variety of structures. For example, the auxiliary air duct 30 is an integral structure, for example, the auxiliary air duct 30 is a whole pipe. For the convenience of connection, in another embodiment, the auxiliary air duct 30 may include a joint 31 and a main pipe 32. The joint 31 may be provided with an air inlet interface 311 and an air outlet interface 312. The direction of the air inlet interface 311 intersects with the direction of the air outlet interface 312. In other words, the central axis of the air inlet interface 311 intersects with the central axis of the air outlet interface 312. The air inlet interface 311 is used to dock with some of the air-conditioning outlets 21 among the multiple air-conditioning outlets 21. The air outlet interface 312 docks with the first port of the main pipe 32, and the second port of the main pipe 32 extends toward the front or rear of the vehicle, which is farther away from the air conditioner 20.

[0066] Since the air-conditioning outlet 21 is located on the top wall 101 of the vehicle body 10, and the fixed air duct 12 extends generally along the length direction of the vehicle, and the fixed air duct 12 and the auxiliary air duct 30 are located below the top wall 101, the joint 31 in the above structure is designed to be a structure that can be turned and connected, and then by designing the joint 31, the auxiliary air duct 30 can be more easily connected to the air-conditioning outlet 21.

[0067] In the embodiment of the present application, the structure of the connector 31 can be various, as long as it can be easily turned and connected. In a specific embodiment, the inner wall of the connector 31 opposite to the air inlet interface 311 can be a curved inner wall, and the curved inner wall can smoothly connect the air inlet interface 311 and the main tube 32. In this structure, the curved inner wall can smoothly guide the cold air or warm air entering the air inlet interface 311 from the air-conditioning outlet 21, thereby reducing the obstruction of the inner wall of the connector 31 to the cold air or warm air, so that the cold air or warm air enters the connector 31 and enters the main tube 32 as quickly as possible with less obstruction. It can be seen that the connector 31 with this structure is conducive to the rapid transmission of cold air or warm air.

[0068] In order to facilitate connection, the auxiliary air duct 30 provided in the embodiment of the present application may also include a connecting plate 34, which can be fixed to the top of the vehicle body 10. The connecting plate 34 is provided with an avoidance hole 341. The joint 31 can be fixed to the top of the vehicle body 10 by welding, bonding, connecting with a connector, etc., and the air inlet interface 311 is docked with the avoidance hole 341. The connecting plate 34 can also be a reinforcing plate, and the connecting plate 34 can be fixed to the top wall 101 by a threaded connector, thereby forming a solid foundation, thereby providing conditions for the subsequent installation of the joint 31. The joint 31 can also be fixed to the connecting plate 34 by a threaded connector. It should be noted that the embodiment of the present application does not limit the specific fixing method between the joint 31 and the connecting plate 34 and between the connecting plate 34 and the top wall 101.

[0069] As described above, the orientation of the air inlet 311 intersects the orientation of the air outlet 312. To avoid obstructing the flow of cold or warm air, in one embodiment, the orientation of the air inlet 311 and the orientation of the air outlet 312 can be greater than or equal to 90 degrees. Specifically, the orientation of the air inlet 311 and the orientation of 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 tube 32. This structure is more suitable for the positional relationship between the top wall 101 and the main tube 32.

[0070] In the embodiment of the present application, the first port of the main tube 32 is fixedly docked with the air outlet interface 312. Specifically, the first port of the main tube 32 and the air outlet interface 312 can be sealed and docked. To facilitate docking, the first end of the main tube 32 with the first port can be plugged into the air outlet interface 312 to achieve connection, or the end of the connector 31 provided with the air outlet interface 312 can be plugged into the first port of the main tube 32 to achieve connection. To improve the stability of the connection, the first end of the main tube 32 where the air outlet interface 312 is located can be further fixedly connected to the first end of the main tube 32 by tightening screws, thereby improving the stability of the connection between them.

[0071] In one embodiment, the auxiliary air duct 30 can be a non-retractable structure. Considering that different types of vehicles, or vehicles of the same type but different sizes, may require the in-vehicle air conditioning system disclosed in the embodiments of this application, in another embodiment, the main tube 32 can be a telescopic tube. The main tube 32 can be extended and retracted to change length, thereby adapting to vehicles of different sizes. Specifically, the second end of the main tube 32 can be moved relative to the first end of the main tube 32 along the air supply direction of the fixed air duct 12 to achieve the expansion and contraction of the main tube 32. Specifically, the main tube 32 can be made of a retractable elastic material.

[0072] In other embodiments, the main tube 32 can be designed as a retractable structure to achieve extension and retraction. The embodiments of the present application do not limit the retractable structure of the main tube 32. For example, in one embodiment, the main tube 32 is a bellows that can be folded to achieve extension and retraction. In another embodiment, the main tube 32 may include a fixed tube section 321 and a movable tube section 322, and the first port of the fixed tube section 321 is fixedly docked with the air outlet interface 312. It should be noted that the first port of the fixed tube section 321 is also the first port of the main tube 32 described above. The movable tube section 322 is lined within the fixed tube section 321. The fixed tube section 321 can slide with the movable tube section 322 to achieve extension and retraction of the main tube 32. The extension and retraction of the main tube 32 actually realizes that the length of the auxiliary air duct 30 is adjustable, thereby enabling the auxiliary air duct 30 to meet the requirements of vehicles of different sizes for the auxiliary air duct 30. At the same time, in this structure, the movable pipe section 322 is lined in the fixed pipe section 321 and slides relative to the fixed pipe section 321 , and 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 tube section 322 can be sleeved outside the fixed tube section 321, with the fixed tube section 321 being able to slidably engage with the movable tube section 322. Compared to the case where the movable tube section 322 is slidably positioned within the fixed tube section 321, the radial dimension of the movable tube section 322 is larger than that of the fixed tube section 321 when the movable tube section 322 is sleeved outside the fixed tube section 321. In embodiments where the movable tube section 322 and the fixed tube section 321 are made of the same material and have the same length, a larger radial dimension of the movable tube section 322 indicates a heavier movable tube section 322. In some installation environments, the second end of the main tube 32 is unsupported. In such cases, the main tube 32 can essentially be a cantilever structure connected to the joint 31. Therefore, sleeved outside the fixed tube section 321, the movable tube section 322 increases torque. Therefore, lining the fixed tube section 321 with the movable tube section 322 helps reduce torque, thereby contributing to the structural stability of the auxiliary air duct 30.

[0074] In the structure of the auxiliary air duct 30, the number of movable pipe segments 322 can be one or multiple, and the embodiments of the present application do not limit the number of movable pipe segments 322. Similarly, the embodiments of the present application do not limit the length of the movable pipe segments 322. In one embodiment, there is only one movable pipe segment 322. If a larger 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, thereby simplifying assembly. Considering that the auxiliary air duct 30 can be more flexibly adapted to various vehicle models, in other embodiments, there can be multiple movable pipe segments 322. If a larger range of extension and retraction is required, multiple movable pipe segments 322 can be sequentially lined within the fixed pipe segment 321 or sequentially sleeved onto the fixed pipe segment 321. The fixed pipe segment 321 slides with adjacent movable pipe segments 322, and two adjacent movable pipe segments 322 slide with each other. In this structure, the main tube 32 can be extended and retracted within a larger range by sliding more tube segments. At the same time, since there are a large number of tube segments, there is no need to design each tube segment (fixed tube segment 321 and movable tube segment 322) to be longer, which is conducive to the overall size of the main tube 32 being smaller after contraction, and can adapt to installation in smaller vehicles.

[0075] The joint 31, fixed pipe section 321, and movable pipe section 322 can be made of non-metallic materials, such as plastic or rubber, to reduce the weight of the auxiliary air duct 30 and facilitate installation of the auxiliary air duct 30 within the vehicle body 10. In other embodiments, the joint 31, fixed pipe section 321, and movable pipe section 322 can be made of metal, such as iron or aluminum. The present embodiment does not limit the specific materials of the components of the auxiliary air duct 30.

[0076] In the embodiment of the present application, the movable tube segment 322 is slidably fitted with the fixed tube segment 321. Specifically, there can be a large friction between the movable tube segment 322 and the fixed tube segment 321, so that the movable tube segment 322 can maintain relative stillness after extending from or retracting into the fixed tube segment 321, thereby maintaining the main tube 32 at the adjusted length. Similarly, in an embodiment where there are multiple movable tube segments 322, two adjacent movable tube segments 322 are slidably fitted with each other. Specifically, there can be a large friction between the two adjacent movable tube segments 322, so that the movable tube segment 322 can maintain relative stillness after extending from or retracting into the other movable tube segment 322, thereby maintaining the main tube 32 at the adjusted length.

[0077] It should be noted that there are various ways to maintain the relative stillness of the fixed pipe segment 321 and the adjacent movable pipe segment 322, as well as to maintain the relative stillness of the two adjacent movable pipe segments 322, and are not limited to the friction between them. In other embodiments, the auxiliary air 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 via 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 slide in cooperation. When the locking assembly 33 is in the locked state, the locking assembly 33 can play a fixing role, thereby fixing the fixed pipe segment 321 and the adjacent movable pipe segment 322. In one embodiment, the locking assembly 33 can be at least one locking screw. The locking screw achieves a fixed connection between the two by cooperating with the connecting holes on the fixed pipe segment 321 and the movable pipe segment 322. In this embodiment, the locking of the locking assembly 33 can improve the fixing stability of the fixed pipe section 321 and the movable pipe section 322, thereby avoiding the problem of length change of the auxiliary air duct 30 due to shaking and vibration during vehicle driving.

[0078] In another embodiment, the locking assembly 33 may be a gripping structure, such as a clamping structure. For example, in an embodiment where the fixed pipe segment 321 is sleeved outside the adjacent movable pipe segment 322, the locking assembly 33 may grip the fixed pipe segment 321, thereby causing the fixed pipe segment 321 to deform and thus grip 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 relative stillness between the two.

[0079] The embodiment of the present 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. The two ends of the clamping member 331 face each other and each have a connection hole 3311. When the locking assembly 33 is locked, a bolt 332 passes through the connection hole 3311 and is tightened by a nut 333 to connect the two ends of the clamping member 331, forcing the fixed pipe section 321 to clamp the movable pipe section 322. When the locking assembly 33 is unlocked, the nut 333 is loosened, forcing the fixed pipe section 321 to release the movable pipe section 322, 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 hole 3311 on both ends of the clamping member 331, and then screws on the nut 333 until the nut 333 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 being fixedly connected, the two ends of the clamping member 331 approach 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 therein by deforming itself, and finally realize the fixed connection between the fixed pipe section 321 and the movable pipe section 322, so as to achieve the purpose of keeping the two relatively still. During the unlocking operation, the operator can simply loosen the nut 333 or remove it after loosening it, thereby releasing the fixed connection between the two ends of the clamping member 331. The clamping member 331 then recovers its deformation, allowing its two ends to move away from each other, ultimately releasing the clamping member 331 from its grip on the fixed pipe section 321. The fixed pipe section 321 can then recover its deformation 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 the clamping member 331 better enables the fixed pipe section 321 to grip the movable pipe section 322 through deformation, thereby improving the fixation stability of the movable pipe section 322.

[0082] From the description of the locking process and the unlocking process above, it can be seen that the locking of the locking assembly 33 is essentially to hold the movable pipe section 322 by deforming the fixed pipe section 321, thereby achieving fixation between the fixed pipe section 321 and the movable pipe section 322. It can be seen that designing the fixed pipe section 321 into a structure that is easier to deform is conducive to the locking operation. Based on this, in one embodiment, the fixed pipe section 321 can be a thin-walled tube structure. In other embodiments, the tube wall of the fixed pipe section 321 can be provided with a strip-shaped notch 3211, and the strip-shaped notch 3211 can extend to the first port of the fixed pipe section 321. In the specific locking process, as the holding member 331 is held tightly, the two edges of the strip-shaped notch 3211 will approach each other, thereby making it easier to achieve deformation of the fixed pipe section 321. The essence of this structure is to remove a local area of ​​the fixed pipe section 321 so as to reduce the strength of the fixed pipe section 321 without affecting the function of the fixed pipe section 321, thereby 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 section 321 can be changed to a material that is easily deformable and has a certain strength. For example, the fixed pipe section 321 can be made of rubber. Alternatively, in other embodiments, the sidewalls of the fixed pipe section 321 that form the end portion are partially thinned after a thinning process. This allows the fixed pipe section 321 to be more easily gripped and deformed when the locking assembly 33 is in the locked state, thereby making it easier to grip the movable pipe section 322 through deformation.

[0084] As described above, when there are multiple movable pipe segments 322, two adjacent movable pipe segments 322 slide and nest together. The friction between the two adjacent movable pipe segments 322 is used to maintain the two adjacent movable pipe segments 322 relative to each other. This structure does not require a locking assembly 30, which has the advantage of structural simplicity. As also explained above, the fixed pipe segment 321 and the adjacent movable pipe segment 322 can be fixed by the locking assembly 33, and can slide relative to each other when the locking assembly 33 is unlocked.

[0085] Similarly, in embodiments where there are multiple movable tube segments 322, two adjacent movable tube segments 322 can also be fixedly connected via the locking assembly 33. Specifically, when the locking assembly 33 is in the locked state, the outer movable tube segment 322 of the two adjacent movable tube segments 322 is gripped by the locking assembly 33 and deformed, thereby further gripping the inner movable tube segment 322, ultimately securing the two adjacent movable tube segments 322. When the locking assembly 33 is in the unlocked state, the grip between the outer movable tube segment 322 and the inner movable tube segment 322 is released, allowing the two to slide relative to each other, thereby achieving expansion and contraction of the main tube 32 and adjusting the length of the main tube 32.

[0086] It should be noted that the outer movable pipe section 322 herein refers to the movable pipe section 322 with the larger radial dimension among the two adjacent movable pipe sections 322 that are sleeved together. The inner movable pipe section 322 herein refers to the movable pipe section 322 with the smaller radial dimension among the two adjacent movable pipe sections 322 that are sleeved together.

[0087] In the embodiment where the locking assembly 33 includes a clamping member 331, a bolt 332, and a nut 333, the operator can detach the locking assembly 33 while the locking assembly 33 is unlocked. In this manner, the two adjacent movable pipe segments 322 can more easily retract and slide. Without interfering with the movement of the movable pipe segment 322, the central portion of the clamping member 331 of the locking assembly 33 can be secured to the outer wall of the fixed pipe segment 321 by means of screws, adhesive bonding, or other methods.

[0088] In this embodiment of the present application, the movement of the movable tube section 322 can change the length of the main tube 32, thereby adjusting the length of the entire auxiliary air duct 30 and making the auxiliary air duct 30 more flexible and adaptable. During operation, the outer wall of the movable tube section 322 can be provided with a size marking 3221. The size marking 3221 can indicate the length of the auxiliary air duct 30 after the movable tube section 322 is moved, making it easier for the operator to control the extension of the movable tube section 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 scale line representing the length of the auxiliary air duct 30. The embodiment of the present application 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 a number representing the length of the auxiliary air duct 30, a letter representing the length of the auxiliary air duct 30, and a scale line representing the length of the auxiliary air duct 30.

[0090] In an embodiment of the present application, the shapes of the fixed pipe section 321 and the movable pipe section 322 can be adapted to each other, and the shapes of the two adjacent movable pipe sections 322 can be adapted to each other, so as to improve their compactness after assembly and avoid leakage of cold air or warm air in the auxiliary air guide 30 during the process of guiding cold air or warm air. For example, in one embodiment, the fixed pipe section 321 and the movable pipe section 322 can both be rectangular tubes, circular tubes, or elliptical tubes. The embodiment of the present application does not limit the specific shapes of the fixed pipe section 321 and the movable pipe section 322. Similarly, the shape of the joint 31 can be adapted to the shape of the main tube 32. For example, the air outlet interface 312 of the joint 31 can be a rectangular opening, and the main tube 32 can be a rectangular tube. For another example, the air outlet interface 312 of the joint 31 can be a circular opening, and the main tube 32 can be a circular tube.

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

[0092] The vehicle body 10 is provided with a passenger space 11 and a fixed air duct 12 communicating with the passenger space 11. 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 mounted on the top wall 101 of the vehicle body 10 and has a plurality of air outlets 21. The air outlets 21 are located in and communicate with the fixed air duct 12. The distance between the air conditioner 20 and one of the front and rear ends 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 some of the air conditioning outlets 21. The second end of the auxiliary air duct 30 extends toward the front or rear of the vehicle, which is farther away from the air conditioner 20.

[0095] To improve the efficiency of delivering cool 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. The air conditioning outlets 21 are arranged in two rows, each row of which may include multiple air conditioning outlets 21. At least one of the two fixed air ducts 12 may be provided with an auxiliary air duct 30, which communicates with a portion of the air conditioning outlets 21 located within the same fixed air duct 12. In this case, a portion of the air conditioning outlets 21 within the same fixed air duct 12 may interface with the auxiliary air duct 30, then extend through the auxiliary air duct 30 toward the front or rear of the vehicle, where the distance to the air conditioning outlets 21 is shorter. The remaining air conditioning outlets 21 within the same fixed air duct 12 then directly output cool or warm air into the fixed air duct 12.

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

[0097] In other embodiments, the air-conditioning outlets 21 may also be distributed in more rows, each row of air-conditioning outlets 21 includes multiple air-conditioning outlets 21, and the two fixed air ducts 12 are connected to at least one row of air-conditioning outlets 21. Of course, in order to consider the uniformity of cold air or warm air transmission, the number of rows of air-conditioning outlets 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 outlets 21.

[0098] In the embodiment of the present application, the fixed air duct 12 can have various structures, which are not limited by the embodiment of the present application. In one embodiment, the fixed air duct 12 can be a metal pipe fixed in the vehicle body 10.

[0099] In another embodiment, the vehicle body 10 has a top wall 101 and two opposite side walls 102. The top wall 101 forms a corner with the two opposite side walls 102 of the vehicle body 10 respectively. The vehicle body 10 also includes a support plate 13, and a support plate 13 is provided at the corner. The support plate 13 and the corner form a fixed air duct 12, and the support plate 13 is provided with an air duct outlet 131 distributed along the extension direction of the fixed air duct 12. This structure can fix the support plate 13 on the top of the passenger space 11, so that the support plate 13 and the corner constitute the fixed air duct 12, thereby making full use of the existing structure in the vehicle body 10 and simply adding the support plate 13 to form the fixed air duct 12, which is conducive to making full use of the corner to form a fixed air duct 12 with a larger space, and at the same time will not consume too much material.

[0100] At the same time, the support plate 13 is not only used to form a fixed air duct 12 with the corner, but also acts like a reinforcement plate, which can strengthen the local structure of the vehicle body 10. To improve the reinforcement effect, the support plate 13 involved in the embodiment of the present application can be a high-strength metal plate, such as a steel plate or an iron plate.

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

[0102] The vehicle disclosed in the embodiments of the present application may be a tourist bus, an ordinary bus, a train car, a subway car, etc. The embodiments of the present application do not limit the specific type of vehicle.
