Description

Air conditioning air inlet structure and vehicle Technical Field

[0001] The present application relates to the field of vehicle air-conditioning equipment, and in particular to an air-conditioning air inlet structure and a vehicle. Background Art

[0002] The vehicle air conditioner main body has two air intake modes, one is the external circulation mode, that is, the air outside the cab enters the vehicle air conditioner main body. The other is the internal circulation mode, that is, the air inside the cab enters the vehicle air conditioner main body. The air conditioner air inlet structure is used to switch between the internal circulation state and the external circulation state. In the related art, most vehicle air conditioners can only turn on the internal circulation mode or the external circulation mode alone. In winter, the vehicle air conditioner cannot take into account both window defogger and heating. In addition, most traditional air conditioners are offset. For example, the air conditioner main body of a left-hand drive vehicle is set inside the front panel in the middle of the vehicle, while the air inlet and blower are set on the right front panel of the vehicle, resulting in a large overall space occupied by the air conditioner main body, air inlet and blower, and a small passenger compartment space, which affects the comfort of the passengers' legs.

[0034] The present application provides an air-conditioning air inlet structure and a vehicle, wherein the air-conditioning air inlet structure includes an air inlet duct, an air regulating assembly, and a driving assembly. The air inlet duct includes a plurality of external circulation air inlets and a plurality of internal circulation air inlets, and the external circulation air inlets and the internal circulation air inlets are spaced apart in the circumferential direction of the air inlet duct. The air regulating assembly is arranged in the air inlet duct and rotates along the axial direction of the air inlet duct. The side wall of the air regulating assembly includes a plurality of opening surfaces and a plurality of closed surfaces, and the opening surfaces and the closed surfaces are spaced apart in the circumferential direction of the air inlet duct; the interior of the air regulating assembly is provided with an external circulation channel and an internal circulation channel that are independent of each other, and the air regulating assembly is used to rotate around the axial direction of the air inlet duct in the air inlet duct to switch the opening and closing of the external circulation air inlet and the internal circulation air inlet. The driving assembly is connected to the air regulating assembly and is used to drive the air regulating assembly to rotate so that the air regulating assembly switches between different working modes. Since the air regulating assembly is provided with independent external circulation channels and internal circulation channels, the driving assembly can drive the air regulating assembly to rotate so that part of the external circulation air inlet is connected to the external circulation channel, and part of the internal circulation air inlet is connected to the internal circulation channel. When the air conditioner is in heating mode, the external circulation air inlet is used to introduce outdoor air into the external circulation channel, thereby solving the problem of fogging of the car windows. The internal circulation channel reduces heat loss, improves the heating effect, and saves energy costs by closing the air exchange between indoor and outdoor air. In addition, the internal circulation air inlet of the air conditioning inlet structure is arranged on the side wall of the air inlet duct, and there is no need to design a separate internal circulation air inlet. A rotatable air regulating assembly is provided inside the air inlet duct to switch between the internal circulation mode and the external circulation mode.

[0035] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only 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.

[0036] Figure 1 is a schematic structural diagram of an air conditioner main body 100 according to an exemplary embodiment of the present application, Figure 2 is a cross-sectional view of the air conditioner main body 100 according to an exemplary embodiment of the present application, Figure 3 is a schematic structural diagram of an air conditioner air inlet structure according to an exemplary embodiment of the present application, Figure 4 is a schematic structural diagram of an air conditioner air inlet structure according to another exemplary embodiment of the present application, and Figure 5 is a schematic structural diagram of an air conditioner air inlet structure according to yet another exemplary embodiment of the present application. Referring to Figures 1 to 5, the present application provides an air conditioner air inlet structure 1, comprising an air inlet duct 2, an air adjustment component 3, and a drive component 4. The air inlet duct 2 comprises a plurality of external circulation air inlets 20 and a plurality of internal circulation air inlets 21. The plurality of external circulation air inlets 20 and the plurality of internal circulation air inlets 21 are spaced apart in the circumferential direction of the air inlet duct 2 and staggered with each other in the axial direction of the air inlet duct. The external circulation air inlet 20 and the internal circulation air inlet 21 are arranged circumferentially around the central axis of the air inlet duct 2. Their radial projections are staggered. The external circulation air inlet 20 allows outdoor air to flow in, while the internal circulation air inlet 21 allows indoor air to flow in. The internal circulation air inlet 21 and the external circulation air inlet 20 are spaced apart circumferentially from each other. The air control assembly 3 is disposed within the air inlet duct 2 and rotates axially along the air inlet duct 2. The air control assembly 3 rotates along the central axis of the air inlet duct 2 to switch the internal circulation air inlet 21 and the external circulation air inlet 20 open and closed. The sidewalls of the air control assembly 3 include multiple open surfaces 30 and multiple closed surfaces 31, which are spaced apart circumferentially around the air inlet duct 2. The interior of the air control assembly 3 is provided with independent external circulation channels 36 and internal circulation channels 37. The outer circulation channel 36 and the inner circulation channel 37 are not interconnected, thereby preventing the exchange of air between the outdoor and indoor spaces. The air regulating assembly 3 is used to rotate around the axial direction of the air inlet duct 2 in the air inlet duct 2 to switch the opening and closing of the outer circulation air inlet 20 and the inner circulation air inlet 21. The driving assembly 4 is connected to the air regulating assembly 3 and is used to drive the air regulating assembly 3 to rotate so that the air regulating assembly 3 switches between different working modes. Since independent outer circulation channels 36 and inner circulation channels 37 are provided in the air regulating assembly 3, the driving assembly 4 can drive the air regulating assembly 3 to rotate so that part of the outer circulation air inlet 20 is connected to the outer circulation channel 36, and part of the inner circulation air inlet 21 is connected to the inner circulation channel 37. When the air conditioner is in heating mode, the outer circulation air inlet 20 is used to introduce outdoor air into the outer circulation channel 36, thereby solving the problem of fogging of the car window glass. The inner circulation channel 37 reduces heat loss, improves the heating effect, and saves energy costs by closing the exchange of air between the indoor and outdoor spaces. The orthographic projection / projection plane in the radial direction of the air inlet duct 2 refers to a plane parallel to a cross section perpendicular to the central axis of the air inlet duct 2. The orthographic projection / projection plane in the radial direction of the air register assembly 3 refers to a plane parallel to a cross section perpendicular to the central axis of the air register assembly 3.Furthermore, the internal circulation air inlet 21 of the air conditioning inlet structure 1 is located on the side wall of the air inlet duct 2, eliminating the need for a separate internal circulation air inlet 21. A rotatable air adjustment assembly 3 is provided within the air inlet duct 2 to switch between internal and external circulation modes. This arrangement results in a simple structure for the air conditioning inlet structure 1, a small footprint, and universal adaptability to accommodate a variety of vehicle models.

[0037] The driving component 4 is used to drive the air conditioning component 3 to switch between the first working mode, the second working mode and the third working mode. The air conditioning air inlet structure 1 of the present application is set on the air inlet side of the air conditioning body 100, and the air conditioning body 100 includes an internal circulation mode, an external circulation mode and an internal and external circulation mode.

[0038] When the air conditioning assembly 3 is in the first operating mode, the external circulation mode is on, the external circulation air inlet 20 coincides with the open surface 30, and the internal circulation air inlet 21 coincides with the closed surface 31, so that the external circulation air inlet 20 is connected to the external circulation channel 36. Outdoor air enters the external circulation channel 36 through the external circulation air inlet 20 and the open surface 30, and then enters the air conditioner main body 100 through the external circulation channel 36.

[0039] When the air conditioning assembly 3 is in the second operating mode, the internal circulation mode is on, the internal circulation air inlet 21 coincides with the open surface 30, and the external circulation air inlet 20 coincides with the closed surface 31, so that the internal circulation air inlet 21 is connected to the internal circulation channel 37. Indoor air enters the internal circulation channel 37 through the internal circulation air inlet 21 and the open surface 30, and then enters the air conditioner main body 100 through the internal circulation channel 37.

[0040] When the air conditioning assembly 3 is in the third operating mode, the internal and external circulation modes are enabled. A portion of the opening surface 30 overlaps with the external circulation air inlet 20, and the remaining portion overlaps with the internal circulation air inlet 21. This connects the external circulation air inlet 20 with the external circulation channel 36, and the internal circulation air inlet 21 with the internal circulation channel 37. The sum of the sizes of the openings connecting the external circulation air inlet 20 with the external circulation channel 36 and the internal circulation air inlet 21 with the internal circulation channel 37 is the same as the opening size of the opening surface 30. This third operating mode is suitable for winter. Outdoor air enters the external circulation channel 36 through the external circulation air inlet 20 and the portion of the opening surface 30, and then enters the air conditioner main body 100 through the external circulation channel 36. The outdoor air is blown toward the vehicle's front windshield, introducing dry outdoor air to alleviate the problem of fogging on the window. Simultaneously, indoor air enters the internal circulation channel 37 through the internal circulation air inlet 21 and the portion of the opening surface 30, and then enters the air conditioner main body 100 through the internal circulation channel 37. Indoor air can be used for heating, providing a warm cabin environment. By sealing the air exchange between indoor and outdoor, heat loss is reduced, the heating effect is improved, and energy costs are saved.

[0041] In the embodiment shown in Figures 4 and 5, the air regulating assembly 3 includes a rotating shaft 32, which is arranged along the center line of the air regulating assembly 3. A first fixing member 200 and a second fixing member 201 are provided at both ends of the air inlet duct 2. A first mounting hole 202 is provided in the middle of the first fixing member 200, and a second mounting hole 203 is provided in the middle of the second fixing member 201. The first fixing member 200 and the second fixing member 201 intersect in their radially projected portions with respect to the air regulating assembly 3. The rotating shaft 32 is rotatably provided through the first mounting hole 202 and the second mounting hole 203. The driving assembly 4 is fixed to the second fixing member 201, and the driving assembly 4 drives the rotating shaft 32 to rotate, thereby driving the air regulating assembly 3 to perform reciprocating motion, thereby controlling the air conditioning inlet structure 1 to switch between the first working mode, the second working mode, and the third working mode.

[0042] In the embodiment of the present application, the drive mechanism is a stepper motor. Stepper motors are simple to control, highly accurate, and relatively inexpensive. They can precisely control the rotation angle of the air adjustment assembly 3, thereby precisely controlling the overlap angle between the external circulation air inlet 20 and the opening surface 30, as well as the overlap angle between the internal circulation air inlet 21 and the opening surface 30.

[0043] In the embodiment shown in FIG2 , the air inlet duct 2 includes a cylindrical duct body 22 and an external circulation duct 23 connected to the duct body 22. The external circulation air inlet 20 is located on the side wall of the duct body 22, and the external circulation air inlet 20 is connected to the external circulation air duct 23. Outdoor air passes through the external circulation air duct 23 and the external circulation air inlet 20 into the external circulation channel 36 in the air adjustment component 3. In addition, the external circulation air duct 23 is arranged near the lower crossbeam of the vehicle's front windshield, the structure of the external circulation air inlet 20 is simple, and the length of the external circulation air duct 23 is shortened, which can reduce the noise in the external circulation air duct 23. The shortened length of the external circulation air duct 23 shortens the length of the air conditioning air inlet structure 1 in the vehicle length direction, thereby reducing the volume of the air conditioning air inlet structure 1 and reserving more layout space for the cabin and the passenger compartment.

[0044] In the embodiment shown in FIG3 , a plurality of external circulation air inlets 20 are relatively arranged on the side wall of the air inlet duct 2. A plurality of internal circulation air inlets 21 are relatively arranged on the side wall of the air inlet duct 2. The external circulation air inlet 20 is arranged on the side of the side wall of the air inlet duct 2 close to the drive assembly 4, and the internal circulation air inlet 21 is arranged on the side of the side wall of the air inlet duct 2 away from the drive assembly 4. In the embodiment of the present application, two external circulation air inlets 20 are relatively arranged on both sides of the side wall of the air inlet duct 2 along the first direction X1, and the two external circulation air inlets 20 are arranged on the side of the air inlet duct 2 close to the drive assembly 4, and two internal circulation air inlets 21 are relatively arranged on both sides of the side wall of the air inlet duct 2 along the second direction X2, and the two internal circulation air inlets 21 are arranged on the side of the air inlet duct 2 away from the drive assembly 4. The orthographic projections of the external circulation air inlet 20 and the internal circulation air inlet 21 in the radial direction of the air inlet duct 2 are staggered with each other. With such arrangement, the structures of the internal circulation air inlet 21 and the external circulation air inlet 20 are simple, which can reduce the space occupied by the air conditioning air inlet structure 1 and reserve more layout space for the cabin and the passenger compartment.

[0045] In the embodiment shown in Figures 4 and 5, one end of the air-regulating assembly 3 is enclosed, with the drive assembly 4 positioned outside the enclosed structure. The other end of the air-regulating assembly 3 is provided with an external circulation outlet 34 and an internal circulation outlet 35. The radial projections of the external circulation inlet 20 and the internal circulation inlet 21 are staggered relative to each other in the air inlet duct 2. The external circulation outlet 34 communicates with the external circulation channel 36, while the internal circulation outlet 35 communicates with the internal circulation channel 37. Outdoor air enters the external circulation channel 36 through the external circulation inlet 20 and the partially open surface 30, and enters the air conditioner main body 100 through the external circulation outlet 34. This outdoor air is blown toward the vehicle's front windshield, introducing dry outdoor air to alleviate fogging. Simultaneously, indoor air enters the internal circulation channel 37 through the internal circulation inlet 21 and the partially open surface 30, and enters the air conditioner main body 100 through the internal circulation outlet 35. This indoor air can be heated, providing a warm cabin environment. By closing the air exchange between indoor and outdoor, heat loss is reduced, heating effect is improved, and energy costs are saved.

[0046] In the embodiment shown in Figures 4 and 5, the interior of the air regulating assembly 3 includes a plurality of limit members 33, and the limit members 33 are used to divide the interior of the air regulating assembly 3 into an outer circulation channel 36 and an inner circulation channel 37 that are independent of each other. One end of the limit member 33 is connected to the rotating shaft 32, and the other end of the limit member 33 is connected to the side wall of the air regulating assembly 3. Some of the limit members 33 among the plurality of limit members 33 are enclosed with the closed surface 31 to form an outer circulation channel 36, and some of the limit members 33 among the plurality of limit members 33 are enclosed with the closed surface 31 to form an inner circulation channel 37. The outer circulation channel 36 and the inner circulation channel 37 are not interconnected, thereby preventing the exchange of air between the outdoor and indoor spaces.

[0047] Specifically, the limiting member 33 includes a plurality of first limiting portions 330 and a plurality of second limiting portions 331. The first limiting portion 330 and the second limiting portion 331 are planes extending along the axial and radial directions of the air inlet duct 2, and the plane where the first limiting portion 330 is located is perpendicular to the plane where the second limiting portion 331 is located. One end of the plurality of first limiting portions 330 is connected to the rotating shaft 32, and the plurality of first limiting portions 330 are spaced apart in the circumferential direction of the air inlet duct 2, and some of the first limiting portions 330 are staggered in the axial direction of the air inlet duct. The second limiting portion 331 is connected to the first limiting portion 330 and the rotating shaft 32, and the plurality of second limiting portions 331 are spaced apart in the axial direction of the air inlet duct 2, and some of them are staggered in the radial direction of the air inlet duct. Part of the first limiting portion 330 and part of the second limiting portion 331 of the plurality of limiting members 33 are combined with the closed surface 31 to form an outer circulation channel 36, and part of the first limiting portion 330 and part of the second limiting portion 331 of the plurality of limiting members 33 are combined with the closed surface 31 to form an inner circulation channel 37. Among them, the first limiting portion 330 and the second limiting portion 331 are planes arranged along the axial and radial directions of the air inlet duct 2. Specifically, the first limiting portion 330 is a fan-shaped plane perpendicular to the rotating shaft 32, and the central angle corresponding to the fan-shaped plane is 90°. In the embodiment of the present application, there are three first limiting portions 330, which are used to separate the opening surface 30 so that the outer circulation channel 36 is not connected to the inner circulation channel 37. The second limiting portion 331 is arranged along the radial direction of the air inlet duct 2 and is a rectangular plane. The second limiting portion 331 is vertically connected to one side of the first limiting portion 330. In an embodiment of the present application, there are four second limiting portions 331, which are used to cooperate with the first limiting portion 330 to form an independent outer circulation channel 36 and inner circulation channel 37. This arrangement can separate the outer circulation channel 36 from the inner circulation channel 37, preventing the exchange of air between indoor and outdoor. This allows the addition of a third working mode, in which the inner and outer circulation modes are turned on, with outdoor air blowing toward the front windshield of the vehicle. The introduction of dry outdoor air solves the problem of fogging on the windows. The indoor air can be used for heating, providing a warm passenger cabin environment. By sealing the exchange of air between indoor and outdoor, heat loss is reduced, the heating effect is improved, and energy costs are saved.

[0048] In the embodiments shown in Figures 2 and 3, the external circulation air inlet 20 includes a plurality of air inlet holes arranged in a grid shape, and the internal circulation air inlet 21 includes a plurality of air inlet holes arranged in a grid shape. In this manner, the grid-shaped external circulation air inlet 20 and the internal circulation air inlet 21 can block some debris from entering the air-conditioning body 100. The plurality of air inlet holes are arranged at intervals along the axial and circumferential directions of the air inlet duct 2. The length range of the air inlet hole is 22mm-25mm, and the length of the air inlet hole can be 22mm, 23mm, 24mm or 25mm, which is not limited in this application. In some embodiments, a filter can also be provided on the outside of the external circulation air inlet 20 and the internal circulation air inlet 21 to filter out smaller debris.

[0049] In an embodiment of the present application, an air conditioning air inlet structure 1 is applied to a vehicle. The vehicle includes a dash panel 102 extending vertically, an air inlet duct 2 located above the dash panel 102, and an internal circulation air inlet 21 located on the rear side of the dash panel. The dash panel 102 is used to prevent exhaust gas, noise, and excess heat from the vehicle's engine compartment from entering the passenger compartment. In an embodiment of the present application, the dash panel 102 is arranged in a vertical direction. The vehicle also includes a crossbeam 103. The crossbeam 103 and the dash panel 102 form a cavity. The crossbeam 103 connects the dash panel 102 to the longitudinal beams on both sides of the engine compartment and the vehicle body, thereby increasing the rigidity and strength of the dash panel 102. This arrangement can increase the strength of the dash panel 102 while reducing the space occupied by the dash panel 102, thereby reserving more space for the passenger compartment and engine compartment, which is conducive to the architecture accommodating multiple platforms and multiple vehicle models.

[0050] With reference to Figures 1 and 2, the present application also provides a vehicle comprising an air conditioning inlet structure 1 as described in any of the above embodiments. The vehicle also includes an air conditioning main body 100, with the air conditioning inlet structure 1 disposed on the air inlet side of the air conditioning main body 100. The air conditioning main body 100 includes a first air duct 104 and a second air duct 105. The internal circulation air outlet 35 is connected to the first air duct 104, and the external circulation air outlet 34 is connected to the second air duct 105. Outdoor air enters the air conditioning main body 100 through the external circulation duct 36, the external circulation air outlet 34, and the second air duct 105.

The air conditioning main body 100 also includes a blower 5, a filter element 6, an evaporator 7, a heater core 8, air conditioning piping 9, and a plurality of air ducts 10. The blower 5 is configured to draw air from the air conditioning inlet structure 1 into the blower 5 through the rotation of the impeller, and the air enters the air conditioning main body 100 under the action of centrifugal force. After entering the air conditioner main body 100, air is filtered by the filter element 6, absorbed by the evaporator 7, or heated by the heater core. The air is then discharged into the passenger compartment through multiple air ducts 10. Air conditioning ducts 9 are located on the side of the air conditioner main body 100. When the air conditioner air inlet structure 1 is in the third operating mode, outdoor air is blown toward the vehicle's front windshield, introducing dry outdoor air to alleviate the problem of window fogging. Simultaneously, indoor air is heated through the first air duct 104 and flows into the passenger compartment, providing a warm cabin environment. By sealing off the exchange of indoor and outdoor air, heat loss is reduced, heating efficiency is improved, and energy costs are saved. The air conditioner air inlet structure 1 of the present application occupies a small space, facilitating the layout of the air conditioning ducts 9. The air conditioner main body 100 of the present application is centrally located at the front of the vehicle. Combined with the air conditioner air inlet structure 1, the vehicle's air conditioner can be reduced in size, leaving more space for air conditioning duct routing, the passenger compartment, and the engine compartment.
