[0041] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] Reference below Figure 1-Figure 17 A surface-blowing damper 100 , an air conditioning device 1000 , and a vehicle according to an embodiment of the present invention are described.

[0043] like Figure 1-Figure 5 and Fig.11 As shown, the face-blowing damper 100 according to the embodiment of the utility model is arranged in the face-blowing air duct 220 of the air-conditioning device 1000, and includes a first damper assembly 10 and a second damper assembly 20.

[0044] Among them, the first damper assembly 10 is pivotally connected to the blowing surface air duct 220, the first damper assembly 10 can rotate around the pivot axis, and the side blowing surface of the first damper assembly 10 is provided with a side air outlet 111; the second damper assembly 20 can be woundly arranged in the first damper assembly 10, and the second damper assembly 20 can be wound to open or close the side air outlet 111.

[0045] Specifically, the face-blowing damper 100 of the present application can be rotatably arranged in the face-blowing air duct 220, and the face-blowing damper 100 is composed of a first damper assembly 10 and a second damper assembly 20. The first damper assembly 10 is pivotally connected to the face-blowing air duct 220, and the pivot shaft is fixed to the face-blowing air duct 220. The first damper assembly 10 can rotate around the pivot shaft. The rotation of the first damper assembly 10 causes the face damper 100 to rotate in the face-blowing air duct 220. The face damper 100 can form different ventilation cross-sections with the face-blowing air duct 220 at different rotation positions.

[0046] It should be noted that the first damper assembly 10 has a side blowing surface and a middle blowing surface, and a side air outlet is opened on the side blowing surface thereof. The second damper assembly 20 is arranged in the side blowing surface of the first damper assembly 10. The second damper assembly 20 is constructed as a winding structure, which can rotate in the first damper assembly 10. The winding part of the second damper assembly 20 can be extended or retracted when it is rotated. The rotation of the second damper assembly 20 can make its winding part extend to the side air outlet 111 to cover the side air outlet 111. The rotation of the second damper assembly 20 can also make its winding part retracted to open the side air outlet 111, so that the second damper assembly 20 can open or close the side air outlet 111 by winding.

[0047] According to the face-blowing damper 100 of the embodiment of the utility model, the face-blowing damper 100 is composed of a rotatable first damper assembly 10 and a windable second damper assembly 20. The second damper assembly 20 can selectively open or close the side air outlet 111 according to the different rotation positions of the first damper assembly 10, forming a face-blowing damper 100 with a simple structure and convenient control. The second damper assembly 20 is wound in the first damper assembly 10, which can save space and improve space utilization, making the overall layout of the face-blowing damper 100 more reasonable, and convenient for controlling the opening and closing of the side air outlet 111, making the operation simpler. Through the movement of the face-blowing damper 100, it is convenient to control the air outlet of the face air duct 220.

[0048] like Figure 1 and Figure 10-11 As shown, in some embodiments, the first damper assembly 10 has a first damper plate 11 and a pivot shaft 12, the pivot shaft 12 is connected to the first damper plate 11, and the rotation of the pivot shaft 12 drives the first damper plate 11 to switch between an open state and a closed state; in the open state, the first damper plate 11 rotates to disengage from the side wall of the face air duct 220; in the closed state, the first damper plate 11 contacts the side wall of the face air duct 220.

[0049] Specifically, the pivot shaft 12 is fixedly connected to the housing, and the first damper plate 11 is connected to the pivot shaft 12. The first damper plate 11 can rotate around the pivot shaft 12 in the face-blowing air duct 220. A damper stop 280 is provided on the side wall of the face-blowing air duct 220. When the first damper plate 11 rotates around the pivot shaft 12 until the end of the first damper plate 11 contacts the damper stop 280, the first damper plate 11 is in a closed state. In this state, the first damper plate 11, because its two ends are respectively in contact with the damper stop 280 and the side wall of the face-blowing air duct 220, the two ends of the first damper plate 11 do not form a ventilation cross section with the side wall of the face-blowing air duct 220, and the wind in the housing cannot be passed through the first damper plate 11. The two ends of the first damper plate 11 enter the face-blowing air duct 220; when the first damper plate 11 rotates around the pivot shaft 12 until the end of the first damper plate 11 disengages from the damper stop 280, the first damper plate 11 is in an open state. In this state, the first damper plate 11, since its two ends rotate to disengage from the damper stop 280 and the side wall of the face-blowing air duct 220, the two ends of the first damper plate 11 and the side wall of the face-blowing air duct 220 form two ventilation cross-sections, and the wind in the shell can enter the face-blowing air duct 220 through the two formed ventilation cross-sections.

[0050] With this arrangement, the first damper assembly 10 has a simple structure and is easy to manufacture, and can rotate within the face-blowing air duct 220, thereby ensuring that the first damper assembly 10 can switch between an open state and a closed state, thereby being able to form different ventilation cross-sections, making it easy to control the air intake volume to achieve uniform air output.

[0051] like Figure 2-Figure 5 As shown, in some embodiments, the first damper assembly 10 is provided with a receiving space 13 and a protruding space 14, and the protruding space 14 is in communication with the receiving space 13 and the side air outlet 111. The second damper assembly 20 includes: a second damper plate 21 and a second damper shaft 22, wherein the fixed end of the second damper plate 21 is fixed to the second damper shaft 22, the second damper plate 21 is wound around the second damper shaft 22, and the movable end of the second damper plate 21 is extended or retracted as the second damper shaft 22 rotates; the second damper shaft 22 is disposed in the receiving space 13, and the rotation of the second damper shaft 22 drives the second damper plate 21 to move in the protruding space 14, so as to open or close the side air outlet 111.

[0052] Specifically, a accommodating space 13 and an extending space 14 are provided in the first damper assembly 10, and the second damper assembly 20 is provided in the accommodating space 13. The second damper assembly 20 is constructed as a winding structure, which can rotate in the accommodating space 13. The rotation of the second damper shaft 22 can make the second damper plate 21 wound thereon move in the extending space 14. The extending space 14 is connected with the accommodating space 13 and the side air outlet 111, so that the movable end of the second damper plate 21 can extend to the side of the extending space 14 away from the accommodating space 13, and can also move toward the accommodating space 13 so that the second damper plate 21 is rolled back onto the second damper shaft 22. The extending space 14 is connected with the accommodating space 13 and the side air outlet 111. The second damper plate 21 can open or close the side air outlet 111 when it moves in the extending space 14, thereby controlling the air outlet condition and air outlet volume, which can improve the uniformity of the air outlet, make the operation more convenient and quick, and reduce the difficulty of operation.

[0053] It should be noted that the second damper plate 21 is made of a bendable material that has a certain hardness and toughness. For example, it can be made of a cloth base or thin plastic or other materials. The second damper plate 21 made in this way can be wound around the second damper shaft 22, and when the second damper shaft 22 rotates, the movable end of the second damper plate 21 has sufficient hardness to extend forward or retract backward along the extension space 14.

[0054] With this arrangement, the second damper assembly 20 has a simple structure and is easy to manufacture. This structure facilitates its arrangement inside the first damper assembly 10, and the second damper plate 21 can be extended or retracted by rotating the second damper shaft 22, thereby opening or closing the side air outlet 111, making the operation more convenient and simple.

[0055] like Figure 10-11As shown, in some embodiments, when the first air flap plate 11 is switched from a closed state to an open state, the movable end of the second air flap plate 21 extends toward the side of the extension space 14 away from the accommodating space 13 to close the side air outlet 111; when the first air flap plate 11 is switched from an open state to a closed state, the movable end of the second air flap plate 21 is retracted toward the side where the extension space 14 is connected to the accommodating space 13 to open the side air outlet 111.

[0056] It should be noted that when the first air flap 11 is switched to the open state, the side air outlet 111 is closed, and the two ends of the first air flap 11 are rotated to disengage from the air flap stop 280 and the side wall of the face air duct 220. The two ends of the first air flap 11 and the side wall of the face air duct 220 form two ventilation cross sections. Since the side air outlet 111 is closed, the side air outlet 111 and the face air duct 220 do not form a ventilation cross section. At this time, the wind in the shell enters the face air duct from the two ventilation cross sections at the two ends of the first air flap 11. air duct 220; when the first air damper plate 11 is switched to the closed state, the side air outlet 111 is opened, and the two ends of the first air damper plate 11 are respectively in contact with the air damper stop 280 and the side wall of the face air duct 220, and the two ends of the first air damper plate 11 do not form a ventilation cross section with the side wall of the face air duct 220. Since the side air outlet 111 is opened, the side air outlet 111 and the face air duct 220 form a ventilation cross section. At this time, the wind in the shell enters the face air duct 220 through the ventilation cross section formed by the side air outlet 111.

[0057] In this way, by limiting the rotation state of the first air damper plate 11 and the opening and closing state of the side air outlet 111, the number of ventilation sections entering the face air duct 220 can be controlled, thereby facilitating the control of the air outlet of the face air duct 220, and facilitating the control of the air outlet volume and air outlet ratio to improve the uniformity of the air outlet.

[0058] like Figure 6 As shown, in some embodiments, the second damper shaft 22 is provided with a pin shaft 221, and the first damper assembly 10 is provided with a pin hole 15, and the pin shaft 221 cooperates with the pin hole 15 to make the second damper shaft 22 rotate synchronously with the first damper assembly 10. This arrangement facilitates the synchronous rotation of the second damper assembly 20 and the first damper assembly 10.

[0059] like Figure 7-Figure 8 As shown, in some embodiments, the second damper assembly 20 further includes a first gear shaft 23 and a second gear shaft 24 . The first gear shaft 23 is installed at the end of the second damper shaft 22 , and the second gear shaft 24 is meshed with the first gear shaft 23 .

[0060] Specifically, a first actuator and a second actuator are provided in the shell 200. The first actuator is used to drive the first damper assembly 10 to move. The second gear shaft 24 is installed on the shell 200. The second actuator is used to drive the second gear shaft 24 to rotate. The rotation of the second gear shaft 24 drives the first gear shaft 23 meshing with it to rotate, so that the first damper assembly 10 and the second damper assembly 20 can be driven to move independently.

[0061] It should be noted that if Figure 12-13 As shown, since the blowing face damper 100 has different gears of air volume, in the first gear (the lowest gear), the air volume allocated to the side blowing face may just meet the minimum air volume required by the temperature sensing of the blowing face temperature sensor 290. Due to the small air volume, the side air outlet 111 basically has no wind feeling, which will not make the occupants feel uncomfortable; in the high-grade wind, the overall air volume increases, and the air volume allocated to the side air outlet 111 also increases greatly. At this time, although the minimum air volume requirement for the temperature detection of the blowing face temperature sensor 290 is met, the side air outlet 111 will have a clear wind feeling, which may easily make the occupants feel uncomfortable. The first gear shaft 23 and the second gear shaft 24 are set and meshed, and the second actuator drives the second gear shaft 24 to rotate to realize the independent movement of the second damper assembly 20, so as to facilitate the adjustment of different air volume gears to meet the needs of the occupants.

[0062] This arrangement can realize independent driving of the second damper assembly 20, so that the second damper plate 21 can be driven according to different air volume gears, thereby controlling the ventilation area of ​​the side air outlet 111, and allocating the air volume more reasonably, while meeting the required air volume for detecting the temperature by the surface temperature sensor 290, and will not make the occupants feel uncomfortable, thereby improving the occupant experience.

[0063] like Figure 9-12 As shown, the air conditioning device 1000 according to the embodiment of the utility model comprises: a housing 200 and a face-blowing damper 100 of any one of the above embodiments, the housing 200 has a face-blowing air duct 220, and the face-blowing damper 100 and the face-blowing temperature sensor 290 are provided in the face-blowing air duct 220. The housing 200 also has a defrost air duct 210, and the defrost air duct 210 is provided with a defrost damper 211. In the defrost mode, the defrost damper 211 is in an open state, and the face-blowing damper 100 is in a closed state. At this time, the side air outlet 111 is opened to form a ventilation cross section for air to enter the face-blowing air duct 220, and the face-blowing temperature sensor 290 is used to detect the defrost air flow temperature; in the face-blowing mode, the face-blowing damper 100 is in an open state, and the side air outlet 111 is closed, and the side of the face-blowing damper 100 and the housing 200 form a ventilation cross section for air to enter the face-blowing air duct 220.

[0064] In the prior art, the side air outlet 111 is a normally open air outlet, such as Figure 15-17As shown, in the defrost mode, the air-conditioning device rotates to an open state, the face-blowing damper is in a closed state, the face-blowing damper contacts the damper stop 280 of the shell 200, and the side air outlet 111 is opened. At this time, most of the air flow a will flow along the shell 200 through the defrost air outlet and into the defrost air duct 210, and a small part of the air flow b will flow along the shell 200 through the side air outlet 111 of the face-blowing damper, and then flow through the face-blowing damper into the side face-blowing air duct 220; in the face-blowing mode, the defrost damper 211 is in a closed state, and when the face-blowing damper rotates to an open state and the side air outlet 111 is opened, the end of the face-blowing damper The ventilation cross-sections of the blowing surface channel are the first ventilation cross-section 230 of the side blowing surface, the second ventilation cross-section 240 of the side blowing surface, and the side air outlet 111 on the blowing surface damper, and the ventilation cross-sections of the middle blowing surface only include the first ventilation cross-section 250 of the middle blowing surface and the second ventilation interface 260 of the middle blowing surface. The areas of the first ventilation cross-section 230 of the side blowing surface and the first ventilation cross-section 250 of the middle blowing surface are consistent, the areas of the second ventilation cross-section 240 of the side blowing surface and the second ventilation interface 260 of the middle blowing surface are consistent, and the areas of the side air outlet and the middle air outlet are consistent. Therefore, the air outlet ratio of the side blowing surface must be higher than the air outlet ratio of the middle blowing surface, resulting in inconsistent air outlet ratios of each air outlet.

[0065] The air conditioning device of the present application is in defrost mode, such as Fig.10 As shown, the defrost damper 211 in the defrost duct 210 is in an open state (not in contact with the corresponding damper stop 280), the blowing face damper 100 in the blowing face duct 220 is in a closed state (in contact with the corresponding damper stop 280), and the second damper plate 21 is rotated and retracted by the second damper shaft 22 to open the side air outlet 111. Most of the defrost airflow flows along the shell 200 through the defrost air outlet and enters the defrost air duct 210, and a small part of the defrost airflow flows along the shell 200 through the side air outlet 111 on the first damper plate 11, and then flows through to the blowing face duct 220. The blowing face temperature sensor 290 arranged in the blowing face duct 220 can detect the temperature of the airflow and regard this temperature as the temperature of the defrost airflow, wherein the first damper plate 11 with the side air outlet 111 is the side blowing surface, and the first damper plate 11 without the side air outlet 111 is the middle blowing surface.

[0066] In the blowing mode, Fig.11 and Fig.12As shown, when the blowing face damper 100 is rotated and in the open state, the movable end of the second damper plate 21 extends toward the side of the extension space 14 away from the accommodating space 13, and the second damper plate 21 will cover the side air outlet 111 to close the side air outlet 111. At this time, the side air outlet 111 and the blowing face air duct 220 will not form a ventilation section. In this mode, the ventilation section of the blowing face channel is the first ventilation section 230 of the side blowing face and the second ventilation section 240 of the side blowing face, and the ventilation section of the middle blowing face is the first ventilation section 250 of the middle blowing face and the second ventilation interface 260 of the middle blowing face. Since the area of ​​the first ventilation section 230 of the side blowing face is consistent with the area of ​​the first ventilation section 250 of the middle blowing face, and the area of ​​the second ventilation section 240 of the side blowing face is consistent with the area of ​​the second ventilation interface 260 of the middle blowing face, the side blowing face and the middle blowing face have ventilation sections of the same area, and the air outlet ratio of the side blowing face and the middle blowing face is basically consistent, so that the air outlet ratio of the air-conditioning device 1000 is more uniform and coordinated.

[0067] With this arrangement, the blowing surface temperature sensor 290 can be shared, so that it can measure the temperature of the defrost airflow. There is no need to separately set a temperature sensor for measuring the defrost airflow in the defrost air duct 210, which can save space and material costs, and improve the coordination of the air outlet ratio of the air-conditioning device 1000, so that the air outlet ratio of the side blowing surface and the middle blowing surface is more uniform.

[0068] According to the vehicle of the embodiment of the utility model, including the air conditioning device 1000 in the above embodiment, by setting the above air conditioning device 1000, the uniformity of the air volume flowing through the air duct of the air conditioning device 1000 can be improved, the user's comfort can be improved, the uniformity of the air outlet ratio can be improved, and the air volume can be reasonably distributed.
