TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to an HVAC assembly for a vehicle and the vehicle. BACKGROUND

[0002] The interior space design of a passenger vehicle is one of the important factors affecting the driving comfort. The longitudinal space in the vehicle has a significant impact on comfort. For the front driver, sufficient head and legroom can allow him to maintain a natural sitting posture during driving, reducing fatigue. For the front passenger, ample legroom allows him to stretch his legs easily, improving the comfort of the ride.

[0003] The air volume during the use of the air conditioner needs to be greater than a certain value to meet the comfort requirement, which requires that the cross-sectional area of the air circulation channel cannot be less than a certain value. Ultimately, the result is that the driving space of the front passenger will be invaded, and the comfort will be reduced. Therefore, how to reduce the occupied space of the HVAC assembly is a technical problem that needs to be solved urgently today. CONTENT OF THE UTILITY MODEL

[0007] The HVAC assembly for a vehicle according to the first aspect of the present application can make the damper assembly and the inner wall of the air duct form a closely fitted sliding fit, without the need to reserve a rotating gap, further improving the space utilization rate of the air duct, thereby fully utilizing the space in the vertical direction, reducing the occupation of the space in the front-rear direction of the vehicle, changing the effective cross-sectional area of the air duct by translation in the vertical direction, reducing the rotating avoidance space required by the traditional rotary damper, greatly compressing the volume of the air duct, and further helping to reduce the overall size of the air conditioner box.

[0009] In the above scheme, the first air door and the second air door can both move along the vertical direction of the vehicle, and the movement trajectory is a straight line instead of a circular arc, so that no rotation avoidance space needs to be reserved in the front-rear direction of the vehicle, the additional requirement of the circular arc movement on the space in the front-rear direction of the vehicle is reduced, the volume of the air duct is greatly compressed, the space occupation in the front-rear direction of the vehicle is reduced, which is helpful to reduce the overall size of the air conditioning box and to realize compact layout in the narrow space below the instrument panel, so as to not only reduce the space occupation of the system in the front engine compartment, but also provide more space for the arrangement of key components such as the battery pack and the electronic control system, which is beneficial to the overall space optimization.

[0010] Optionally, along the vertical direction, the air door assembly has a first end and a second end, the first end is located above the second end, and the projection of the first end at least partially overlaps the projection of the second end.

[0049] The interior space design of a passenger car is one of the important factors affecting the driving comfort. The longitudinal space in the car has a significant impact on comfort. For the front driver, sufficient head and legroom can allow him to maintain a natural sitting posture during driving, reducing fatigue. For the front passenger, ample legroom allows him to stretch his legs easily, improving ride comfort.

[0050] The structure of the traditional air conditioning box of the automobile for opening and closing the air flow, adjusting the air flow on the flow path, and mixing the air in different flow paths is called a damper. Through the movement of the damper and the sealing structure of the limit position, the air in one channel is directed to another channel or multiple channels; or the mixed air in multiple channels is directed to another channel.

[0051] The shape of the damper is mostly semicircular and butterfly-shaped. The semicircular damper moves in a circular arc around its semicircular center, and the maximum motion envelope is the area swept by the radius of the circle. The butterfly-shaped damper moves in a circular arc around a point on the end or middle piece as the center, and the maximum motion envelope depends on the distance from the end of the single plate to the farthest point from the center.

[0052] As an example, a split-type air conditioning box is an air transport unit, a heating unit, a refrigeration unit, a filtering unit, etc. to the front compartment of the vehicle body outside the front panel as an external module; the final air distribution channel is placed in the passenger compartment as an internal module. Considering the actual use of the air conditioner, the air after heat exchange by the refrigeration unit and the heating unit must be mixed and then transported to the passenger compartment, so there must be a damper for mixing air flow at the interface between the external module and the internal module.

[0053] The air volume during the use of the air conditioner must be greater than a certain value to meet the comfort requirements, which requires that the air flow passage cross-sectional area cannot be less than a certain value. The damper needs to be able to close a certain channel at the limit position. Therefore, the larger the air volume, the larger the damper radius, and the larger the radius brings a larger motion envelope, which means a larger space occupied. The final result is that it will invade the driving space of the front passengers, reducing comfort.

[0054] Therefore, how to reduce the space occupied by HVAC assemblies is a technical problem that urgently needs to be solved.

[0055] In view of this, in order to reduce the space occupied by the HVAC assembly, this application proposes an HVAC assembly for a vehicle. The damper assembly 200 is disposed in the air duct 110 along the vertical direction Y. The damper assembly 200 is movably disposed in the air conditioning unit 100 to adjust the airflow of the air duct. The damper assembly 200 can form a tight sliding fit with the inner wall of the air duct 110 without the need to reserve a rotation gap, further improving the space utilization rate. This makes full use of the space in the vertical direction Y, reduces the space occupied in the vehicle's front-to-back direction X, and changes the effective cross-sectional area of ​​the air duct 110 by the translation in the vertical direction Y, reducing the rotation avoidance space required by the traditional rotary damper, greatly compressing the volume of the air duct 110, and thus helping to reduce the overall size of the air conditioning unit 100.

[0056] The following is based on the appendix Figure 1 -Appendix Figure 3 This application describes an HVAC assembly for a vehicle proposed in an embodiment.

[0057] An HVAC assembly for a vehicle according to a first aspect of this application includes an air conditioning unit 100 and a damper assembly 200.

[0058] A portion of the air conditioning unit 100 is located in the front engine compartment of the vehicle, and another portion is located in the passenger compartment of the vehicle. The air conditioning unit 100 has an air duct 110. It is understood that the air conditioning unit 100 is divided into a portion of the passenger compartment and another portion of the front engine compartment. The portion of the air conditioning unit 100 in the passenger compartment and the other portion of the air conditioning unit 100 in the front engine compartment can be integrated or separate. This application does not limit this.

[0059] Meanwhile, arranging the air conditioning unit 100 across the front engine compartment and the passenger compartment can make full use of the unused space in both areas, such as the powertrain clearance in the front engine compartment and the space under the instrument panel in the passenger compartment. This avoids the space congestion caused by concentrating the air conditioning unit 100 in a single area, effectively reducing the chance of interference between the HVAC assembly and components such as the powertrain in the front engine compartment, the suspension system, or the seats and center console in the passenger compartment. It also allows for flexible allocation of the air conditioning unit 100's functional modules according to the space dimensions of the two areas. For example, the heat exchange core components can be placed in the front engine compartment, and the air outlet adjustment components can be placed in the passenger compartment, further improving space utilization.

[0060] The damper assembly 200 is disposed in the air duct 110 along the vertical direction Y. The damper assembly 200 is movably disposed in the air conditioning unit 100 to adjust the air flow of the air duct 110.

[0061] In other words, the damper assembly 200 is directly built into the air duct 110, without the need for an additional independent adjustment cavity or external adjustment structure, thus avoiding the occupation of external space of the air duct 110. At the same time, the damper assembly 200 can reduce the size occupied by the vehicle in the left-right direction or the front-back direction X direction compared to the rotation avoidance space required by the traditional rotary damper, which greatly reduces the volume occupied by the adjustment structure and helps to further reduce the overall size of the air conditioning unit 100.

[0062] In other embodiments, please refer to Figure 2 and Figure 3 The damper assembly 200 includes a first damper 210 and a second damper 220. That is, the first damper 210 and the second damper 220 can work together to regulate airflow. With this configuration, the effective cross-sectional area of ​​the air duct 110 can be precisely controlled by changing the relative distance between the first damper 210 and the second damper 220. For example, bringing the first damper 210 and the second damper 220 closer together will reduce the effective cross-sectional area of ​​the air duct 110, while moving them further apart will expand the effective cross-sectional area of ​​the air duct 110. This eliminates the need to add additional installation space in the vehicle's front-to-back or left-to-right directions, reduces the rotation and clearance space required by traditional rotary dampers, and significantly compresses the volume of the air duct 110, thereby helping to reduce the overall size of the air conditioning unit 100.

[0063] In addition, the two dampers move symmetrically along the vertical Y direction, which can ensure that the airflow channel in the duct 110 always maintains a regular rectangular or strip cross section, avoids the airflow deviation and vortex phenomenon that may occur when a single damper moves, greatly reduces wind noise, improves the uniformity of airflow, and makes the air conditioning output more stable.

[0064] Along the vertical direction Y, the first damper 210 and the second damper 220 are movably disposed in the air conditioning unit 100 so that the first damper 210 and the second damper 220 are close to or far from each other.

[0065] Specifically, the first air damper 210 and the second air damper 220 can be arranged sequentially along the vertical direction Y. Both the first air damper 210 and the second air damper 220 can move along the vertical direction Y of the vehicle. The movement trajectory is a straight line rather than an arc. There is no need to reserve rotation and avoidance space in the front-rear direction X of the vehicle. This reduces the additional space requirements of the arc movement in the front-rear direction X of the vehicle and reduces the space occupied in the front-rear direction X of the vehicle. It helps to achieve a compact layout in the narrow space below the dashboard. This not only reduces the space occupied by the system in the front engine compartment, but also provides more space for the placement of key components such as the battery pack and electronic control system, which is conducive to overall space optimization.

[0066] In a specific embodiment, the air conditioning unit 100 is provided with a fixed pulley, a connecting rope, and a track. The track extends along the vertical direction Y of the vehicle. The first air door 210 and the second air door 220 are both slidably mounted on the track. One end of the connecting rope is connected to the first air door 210, and the other end of the connecting rope is connected to the second air door 220. The fixed pulley is fixedly mounted on the inner wall of the air conditioning unit 100. The connecting rope cooperates with the fixed pulley. When the fixed pulley rotates, the height of the two ends of the connecting rope changes, thereby allowing the first air door 210 and the second air door 220 to move closer or further apart.

[0067] As an example, one of the first damper 210 and the second damper 220 is movable, while the other is fixed inside the air conditioning unit 100. This application does not impose any restrictions on this.

[0068] In other embodiments, please refer to Figure 2 and Figure 3 Along the vertical direction Y, the damper assembly 200 has a first end 200a and a second end 200b, with the first end 200a located above the second end 200b. The projection of the first end 200a at least partially overlaps with the projection of the second end 200b. Specifically, the damper assembly 200 may include a damper that can move up and down. When the projection of the first end 200a partially overlaps with the projection of the second end 200b, the thickness direction of the damper intersects the vertical direction Y. When the projection of the first end 200a completely overlaps with the projection of the second end 200b, the thickness direction of the damper is perpendicular to the vertical direction Y.

[0069] This design further reduces the space occupied by the air conditioning unit 100 in the forward and backward X direction within the passenger compartment, improves the structural compactness in the narrow area below the instrument panel, and reduces the probability of spatial interference between the air conditioning unit 100 and the pipes and wiring harnesses extending from the forward engine compartment module.

[0070] In some other embodiments, the damper assembly 200 further includes a slide bar that extends in the vertical direction Y and is disposed in the air conditioning unit 100, and the first damper 210 and the second damper 220 are both slidably disposed on the slide bar.

[0071] Specifically, the first damper 210 and the second damper 220 can be slidably mounted on the slide rod by sliders, and the sliders can be driven by gears and racks, or by a motor, so that the first damper 210 and the second damper 220 can move closer to or further away from each other. This application does not limit this.

[0072] This configuration allows for centralized guidance of the first air damper 210 and the second air damper 220 using only a single slide bar. This helps reduce the vertical space occupied by the air damper assembly 200 in the vehicle, thereby further reducing the space occupied by the air conditioning unit 100 in the passenger compartment and preventing spatial interference between the air conditioning unit 100 and the front engine compartment extension pipes and the internal structure of the instrument panel.

[0073] On the other hand, the slide bar provides a unified linear guide reference for the first damper 210 and the second damper 220, which can strictly constrain the movement trajectory of the first damper 210 and the second damper 220, ensuring that the two are always parallel to each other in the vertical direction Y, which helps to ensure the sealing performance and flow regulation accuracy of the air duct 110.

[0074] This design significantly simplifies the structure of the damper assembly 200, reduces the number of independent guide components, lowers the weight of parts and assembly errors, and at the same time, the slide bar can distribute the force when the damper moves, reduce wear and deformation during long-term use, and improve the operational stability and service life of the damper assembly 200.

[0075] In some other embodiments, the damper assembly 200 further includes a first lead screw and a second lead screw, both of which extend in the vertical direction Y. The first lead screw and the second lead screw are both disposed in the air conditioning unit 100. The threads of the first lead screw and the second lead screw have opposite directions of rotation. The first lead screw cooperates with the first damper 210, and the second lead screw cooperates with the second damper 220.

[0076] In the above scheme, the design of opposite screw rotation direction enables the first damper 210 and the second damper 220 to achieve synchronous and coordinated action. When the first screw and the second screw are driven to rotate, the first damper 210 and the second damper 220 can automatically move closer to each other to reduce the cross-sectional area of ​​the air duct 110 or move away from each other to expand the cross-sectional area of ​​the air duct 110. This not only further reduces the space occupied by the air conditioning unit 100 in the passenger compartment, but also avoids spatial interference with the forward engine compartment extension pipeline and the internal structure of the instrument panel.

[0077] On the other hand, the screw drive has high-precision lead control characteristics. The design of opposite screw threads ensures that the first damper 210 and the second damper 220 move in strict synchronization and the displacement is accurately matched. It can realize stepless fine adjustment of the cross-sectional area of ​​the air duct 110. Compared with the passive guide of the slide bar, it can effectively avoid airflow leakage or adjustment jamming caused by damper skew or misalignment. At the same time, the synchronous action of the two dampers can quickly reach the target flow state, and the adjustment efficiency is significantly improved.

[0078] In other embodiments, please refer to Figure 2 and Figure 3The HVAC assembly also includes a heating unit 300 and / or a cooling unit 400, which are disposed in the air duct 110 and located upstream of the damper assembly 200. That is, the air conditioning unit 100 is also provided with a heating unit 300 or a cooling unit 400, or both heating unit 300 and cooling unit 400 are provided at the same time. With this configuration, the air in the air duct 110 can be heated or cooled, so that the air flowing through the damper assembly 200 can be heated air, cooled air, or a mixture of air.

[0079] This design allows for a more uniform distribution of airflow temperature and velocity into the damper assembly 200, effectively preventing localized overheating or underheating and improving the stability of the outlet air temperature. It also avoids interference with the pipes and wiring harnesses extending from the front engine compartment, ensuring the assembly reliability of the split assembly. This design provides a longer mixing distance for the mixed air, resulting in a more uniform temperature of the mixed air, a smaller temperature difference at the outlet, and greater passenger comfort.

[0080] As an example, the heating unit 300 includes a warm air core, and the cooling unit 400 includes an evaporator.

[0081] In other embodiments, please refer to Figure 2 and Figure 3 The HVAC assembly also includes a heating unit 300 and a cooling unit 400, which are disposed in the air duct 110 and located upstream of the damper assembly 200.

[0082] The HVAC assembly also includes a deflector unit 500 located downstream of the damper assembly 200 along the vehicle's longitudinal direction X.

[0083] With this configuration, the air passing through the heating unit 300 and the cooling unit 400 can quickly reach the airflow guiding unit 500, shortening the airflow distance at the damper after heat exchange, reducing the loss of cold and heat in the air duct 110, and allowing the driver and passengers to quickly feel the target temperature after starting the heating or cooling function, effectively improving the situation of slow heating in winter and delayed cooling in summer.

[0084] In addition, the airflow can be evenly distributed and precisely delivered through the diversion and guidance function of the airflow guiding unit 500. The airflow guiding unit 500 can optimize the airflow direction according to the air outlet needs of the cabin (such as face, feet, defrost air outlets). Combined with the upstream pre-treatment design of the heating / cooling unit 400, it ensures the temperature consistency of the air output from each air outlet, avoiding the problem of local temperature difference in the cabin (such as overheating of the upper body and overcooling of the feet) caused by the difference in airflow path in traditional layouts.

[0085] In other embodiments, please refer to Figure 1 and Figure 2The air conditioning unit 100 includes a first housing 101 and a second housing 102. The first housing 101 is located in the passenger compartment and fixed to the front bulkhead 600 of the vehicle, and the second housing 102 is located in the front engine compartment and fixed to the front bulkhead 600.

[0086] The air duct 110 includes a first air duct 111 and a second air duct 112. The first air duct 111 is disposed in the first housing 101, the second air duct 112 is disposed in the second housing 102, and the damper assembly 200 is disposed in the first air duct 111.

[0087] In the above scheme, the front bulkhead 600 can separate the passenger compartment from the front engine compartment. The second box 102 on the front engine compartment side can carry heating unit 300, cooling unit 400 and other large components that need heat dissipation. The first box 101 on the passenger compartment side only integrates the first air duct 111 and the damper assembly 200, which helps to reduce the space occupied by the air conditioning unit 100 in the passenger compartment. Moreover, the damper assembly 200 is placed on the first air duct 111 on the passenger compartment side, close to the air outlet, which allows for faster adjustment response, reduces flow loss and adjustment delay, and improves user experience.

[0088] In addition, the first housing 101 and the second housing 102 can be connected through the sealing interface of the front bulkhead 600 to form a double seal, which effectively prevents hot air, exhaust gas and dust from entering the passenger compartment from the front engine compartment, thus helping to improve the cabin sealing performance.

[0089] In other embodiments, please refer to Figure 1 and Figure 3 The HVAC assembly also includes a defrost vent 101a, a face vent 101b, and a foot vent 101c. The defrost vent 101a, the face vent 101b, and the foot vent 101c are all located in the first housing 101 and are all connected to the first air duct 111.

[0090] The HVAC assembly also includes an internal circulation air section 102a and an external circulation air section 102b, both of which are located in the second housing 102 and are connected to the second air duct 112.

[0091] In the above scheme, the first housing 101 on the passenger compartment side integrates a defrost vent 101a, a face vent 101b, and a foot vent 101c, while the second housing 102 on the front cabin side concentrates the internal circulation air section 102a and the external circulation air section 102b. This avoids the internal circulation air section 102a and the external circulation air section 102b occupying space in the passenger compartment, which helps to reduce airflow leakage and resistance. Furthermore, the air vents are arranged sequentially along the vertical Y direction, which helps to further reduce the size of the air conditioning unit 100 in the passenger compartment.

[0092] Secondly, embodiments of this application provide a vehicle including an HVAC assembly according to any of the embodiments.

[0093] According to the second aspect of the present application, the vehicle has a smaller overall size of the air conditioning unit 100 due to having the HVAC assembly of any embodiment, providing more space for front passengers and improving ride comfort.

[0094] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
