Description

Technical Field

[0001] This application relates to the field of air conditioning component technology, and in particular to a concealed air outlet. Background Technology

[0002] Car air conditioning vents are an important interior component of a car, usually located on the surface of the center console or diagonally above the seats. When it is necessary to adjust the temperature inside the car, the car air conditioning can be turned on to cool or heat the car, allowing cool or hot air to be discharged from the car air conditioning vents.

[0003] In the prior art, the air conditioning vent of a car includes a housing with an exhaust port on the side wall of the housing. Several vertical blades and several horizontal blades are rotatably arranged inside the housing, and the vertical blades and horizontal blades are connected by a linkage structure. Generally, the horizontal blades (or vertical blades) are located at the exhaust port of the housing, and the vertical blades (or horizontal blades) are located inside the housing. The horizontal blades (or vertical blades) located at the exhaust port of the housing are equipped with a lever. After the air conditioning is turned on, passengers can move the lever to rotate and adjust the rotation of the horizontal blades (or vertical blades) to adjust the direction of the air conditioning airflow, or move the lever along the length of the horizontal blades (or vertical blades) to rotate and adjust the vertical blades (or horizontal blades) inside the housing, thereby adjusting the direction of the air conditioning airflow.

[0004] Regarding the aforementioned technologies, since a car's air conditioning vents need to be set up in multiple locations, and other car accessories also need to be installed in the car's central control area, the housing of the car's air conditioning vents is usually small, resulting in a small exhaust port on the housing. Placing several horizontal (or vertical) blades at the exhaust port will obstruct the airflow from the exhaust port, thereby affecting the exhaust volume of the exhaust port and the rate of temperature regulation inside the car. Summary of the Invention

[0005] To reduce the impact of the blades on the exhaust vent, this application provides a concealed exhaust vent.

[0006] The concealed air outlet provided in this application adopts the following technical solution:

[0007] A concealed air outlet includes a mounting housing, within which concealed vertical blades are rotatably connected. An exhaust port is provided on one side of the mounting housing, and the concealed vertical blades are rotatably connected to the inner side wall of the mounting housing near the exhaust port. A mounting base is connected to the outer side wall of the mounting housing, and a knob is rotatably connected to the mounting base. One end of the knob extends from the exhaust port. A fork linkage is rotatably connected to one end of the knob, and the fork linkage is located inside the mounting housing. The end of the fork linkage away from the knob is rotatably connected to the side wall of the concealed vertical blades.

[0008] By adopting the above technical solution, the mounting base provides a support for the toggle switch. When the airflow direction of the vehicle's air conditioning needs to be adjusted, the toggle switch can be moved, causing it to rotate around the rotatable connection with the mounting base. The rotation of the toggle switch drives the toggle fork linkage to move within the mounting housing, while the toggle fork linkage and the toggle switch rotate relative to each other. The movement of the toggle fork linkage further drives several hidden vertical blades to rotate. Since the hidden vertical blades are rotatably connected to the exhaust vent of the mounting housing, when the hidden vertical blades rotate, they form an angled exhaust duct at the exhaust vent. When the air conditioning air is discharged from the exhaust vent, it passes between the hidden vertical blades. Under the guidance of the tilt of the hidden vertical blades, the original airflow direction is changed, thus achieving the adjustment of the air conditioning airflow direction. Because the hidden vertical blades are located on the inner wall of the mounting housing and connected near the exhaust vent, the hidden vertical blades can adjust the airflow direction without protruding at the exhaust vent, reducing the obstruction of the airflow from the exhaust vent, thereby reducing the impact on the exhaust volume of the vent and reducing the impact on the rate of temperature regulation inside the vehicle. Meanwhile, due to the concealed vertical blades within the mounting housing, passengers can only see the knob at the air vent when adjusting the airflow direction. The knob also appears to float at the air vent, making the air vent look clean and improving its appearance.

[0009] Preferably, the hidden vertical blade has an installation opening on its side wall, and a connecting post is provided on the inner side wall of the installation opening. The fork connecting rod has an elastic snap fastener at one end near the connecting post, and the elastic snap fastener is fastened to the connecting post. The inner side wall of the elastic snap fastener is adapted to the outer side wall of the connecting post, and the opening width of the elastic snap fastener is smaller than the diameter of the inner side wall of the elastic snap fastener.

[0010] Normally, the rotation connection point between the shift fork linkage and the concealed vertical blade is located at the end of the concealed vertical blade. If it is only located at one end of the concealed vertical blade, when the shift fork linkage pushes the concealed vertical blade to rotate, the weight of the concealed vertical blade itself will cause the shift fork linkage to have a poor effect on pushing the concealed vertical blade to rotate, and the end of the concealed vertical blade away from the shift fork linkage is prone to tilting, thus reducing the air guiding effect. Therefore, when the connection point is connected to the end of the concealed vertical blade, connection points and shift fork linkages need to be set at both ends of the concealed vertical blade, making the blade installation process cumbersome. By adopting the above technical solution, when connecting the concealed vertical blade, the shift fork linkage is moved so that the opening of the elastic snap fastener is close to the connecting post, and then... Press the elastic snap-fit ​​buckle firmly, causing the connecting post to insert into the snap-fit ​​buckle. At the same time, the snap-fit ​​buckle inserts into the mounting opening, which makes room for the snap-fit ​​buckle. Because the opening width of the snap-fit ​​buckle is smaller than the diameter of its inner wall, and the inner wall of the snap-fit ​​buckle is adapted to the outer wall of the connecting post, the connecting post is difficult to dislodge from the snap-fit ​​buckle under external force, thus improving the convenience of connecting the concealed vertical blade. At the same time, the mounting opening and the connecting post are located in the middle of the side wall of the concealed vertical blade, making the push of the fork linkage on the concealed vertical blade more even, reducing the number of connection points and the use of the fork linkage, and reducing the possibility of tilting during the rotation of the concealed vertical blade.

[0011] Preferably, the side wall of the mounting housing is provided with an air guide groove, the two side walls of the air guide groove are inclined, and the two inclined side walls of the air guide groove are inclined towards each other from the end closer to the mounting housing to the end farther away from the mounting housing; the mounting base is connected to the outer side wall of the air guide groove, and the exhaust port is opened on the side wall of the air guide groove.

[0012] Generally, when the side walls of the mounting housing are parallel and the hidden vertical blades rotate within the mounting housing, the inner side wall of the mounting housing needs sufficient space for the hidden vertical blades to rotate. This requires the side wall with the exhaust vent to be sufficiently wide, necessitating the use of more material for manufacturing. Furthermore, the diameter of the exhaust vent on the side wall with the exhaust vent needs to be smaller than the area of ​​that side wall. Consequently, when the air conditioner is venting, the inner wall of that side wall without the exhaust vent will obstruct the airflow. By adopting the above technical solution, the inclined design of the air guide duct side wall can reduce the amount of material used in the mounting housing while meeting the requirements for the rotation of the hidden vertical blades. At the same time, when the air conditioner is venting, the inner side wall of the air guide duct can reduce the obstruction of the air conditioning air, making the airflow smoother. In addition, since the inclined two side walls of the air guide duct are inclined towards each other from the end closer to the mounting housing to the end farther away from the mounting housing, an air guide vent is formed at this point. After the air conditioning air enters the air guide duct, the air force is concentrated under the guidance of the two inclined side walls, resulting in a stronger airflow blowing out of the air guide duct.

[0013] Preferably, the knob has a rotating groove at one end near the mounting base, with an opening on the side away from the knob, and a rotating shaft inside the rotating groove; the mounting base has a mounting ring at one end near the knob, the rotating shaft is inserted into the mounting ring, and the rotating groove is simultaneously fastened to the outer wall of the mounting ring; the mounting base has a clearance opening, one end of the rotating groove passes through the clearance opening, and a connecting plate is provided on the side wall of the mounting base, with the mounting ring connected to the mounting base through the connecting plate.

[0014] By adopting the above technical solution, the rotary knob can be rotatably connected to the mounting base through the cooperation of the rotating shaft and the mounting ring. The rotating shaft can be fixedly connected to the fixed covers at both ends of the rotating groove. After the rotating groove is fastened to the outer wall of the mounting ring, it can cover the mounting ring, so that the people inside the vehicle cannot see the mounting ring. The setting of the clearance opening allows one end of the rotating groove to pass through the clearance opening to cover the connecting plate, so that the people inside the vehicle cannot see the connecting plate. This reduces the visibility of the mounting base and its auxiliary structures at the air vent, making the rotary knob more isolated at the air vent and improving the floating effect of the rotary knob at the air vent.

[0015] Preferably, the sidewall of the connecting plate is arc-shaped, and the curvature of the connecting plate is the same as the curvature of the outer sidewall of the rotating groove.

[0016] By adopting the above technical solution, when the dial moves the rotating groove to rotate, one end of the rotating groove will rotate along the inner wall of the connecting plate. Since the curvature of the connecting plate is the same as the curvature of the outer wall of the rotating groove, the inner wall of the connecting plate and the rotating groove are always parallel during the rotation of the rotating groove. Thus, the inner wall of the connecting plate can support and guide the rotation of the rotating groove, making the rotation of the dial more stable.

[0017] Preferably, there are two hidden vertical blades, and a connecting shaft is coaxially provided at the same end of each of the two hidden vertical blades. The two connecting shafts extend from the outer wall of the air guide groove, and a rotating plate is fixedly connected to the same end of each of the two connecting shafts. The two rotating plates are arranged in parallel and located outside the air guide groove. The same hidden connecting rod is rotatably connected to each of the two rotating plates.

[0018] Normally, when a dial is connected to two concealed vertical blades, a fork linkage needs to be installed on both sides of the dial, so that the two fork linkages are connected to the corresponding concealed vertical blades respectively, in order to achieve synchronous adjustment of the two concealed vertical blades by the dial. However, the concealed vertical blades are connected inside the mounting housing, and the diameter of the exhaust port is small, making it inconvenient for the operator to connect two concealed vertical blades continuously. By adopting the above technical solution, the operator can connect only one concealed vertical blade to the fork linkage, and then fix the two rotating pieces to the end of the corresponding connecting shaft extending from the air guide groove. After the two rotating pieces are parallel, the concealed linkage is simultaneously rotated and connected to the two rotating pieces. When the dial is turned to rotate one of the concealed vertical blades, the concealed vertical blade drives the connecting shaft to rotate, which in turn drives the corresponding rotating piece to rotate. The rotation of the rotating piece pushes the concealed linkage to move, which drives the other rotating piece and the connecting shaft to rotate, thereby driving the other concealed vertical blade to rotate. The connection between the connecting shaft, rotating plate, and concealed linkage enables the two concealed vertical blades to rotate in tandem. The rotation of one concealed vertical blade can drive the rotation of the other concealed vertical blade, eliminating the need for operators to set up two fork linkages to connect the knob to the two concealed vertical blades. This reduces the use of fork linkages and improves the speed of connecting the knob to the two concealed vertical blades.

[0019] Preferably, the sidewall of the hidden vertical blade is provided with several layers of absorbent cotton.

[0020] When the temperature is high, if a car is parked in direct sunlight, the interior temperature will rise, causing the temperature of the concealed vertical blades to also rise. In this situation, the driver needs to turn on the air conditioning before entering the car. When the cold air blows out from the air vents, it comes into contact with the concealed vertical blades. Due to the high temperature of the blades, the cold air condenses upon contact, forming water droplets on their surface. If the air conditioning is blowing strongly, these droplets will be dispersed and fall into the car. Simultaneously, some water droplets may flow along the blades into the mounting housing and further infiltrate the air conditioning system, causing damage. By adopting the above technical solution, when the air conditioning is turned on in hot weather, the water droplets formed on the concealed vertical blades are absorbed by the absorbent cotton layer on the side walls of the blades, reducing the accumulation of water droplets on the side walls. This reduces the likelihood of water droplets being dispersed and falling into the car due to strong air conditioning, and also reduces the likelihood of water droplets flowing along the blades into the mounting housing and further infiltrating the air conditioning system, causing damage.

[0021] Preferably, the sidewall of the hidden vertical blade is provided with a connecting strip, and the sidewalls on both sides of the connecting strips are provided with insertion slots. The absorbent cotton layer is provided with insertion rods on both sides. One absorbent cotton layer is located between two adjacent connecting strips, and the insertion rods on both sides of the absorbent cotton layer are respectively inserted into the corresponding insertion slots of the connecting strips on both sides.

[0022] After prolonged use, the absorbent cotton layer not only absorbs moisture but also easily traps dust brought into the vehicle from outside. Therefore, cleaning the absorbent cotton layer is necessary. Using the aforementioned technical solution, operators can move the absorbent cotton layer directly from two adjacent connecting strips, simultaneously moving the connecting rods out of their corresponding slots. Similarly, when installing a new absorbent cotton layer, moving it allows the connecting rods on both sides to insert into the corresponding slots on the connecting strips, completing the installation. The design of the connecting strips and the coordination of the connecting rods and slots make the installation of the absorbent cotton layer on the hidden vertical blade sidewalls quick and easy, facilitating cleaning.

[0023] Preferably, a support plate is provided between the two plug rods of one of the absorbent cotton layers, the two plug rods are connected to both sides of the support plate, and the absorbent cotton layer is connected to the side wall of the support plate.

[0024] Normally, the absorbent cotton layer is flexible. When installing the absorbent cotton layer, two plug rods need to be inserted into the corresponding plug slots simultaneously. The absorbent cotton layer is difficult to position the two plug rods, so the plug rods need to be connected one by one. However, the plug rods are small, making the operation inconvenient. By adopting the above technical solution, the support plate can limit the position of the two plug rods. When connecting the two plug rods, the support plate can be held to align the two plug rods with the corresponding plug slots. Then, the support plate can be moved to insert the two plug rods directly into the plug slots, which improves the speed of operation.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Because the concealed vertical blades are located on the inner wall of the mounting housing and connected near the air vent, they can adjust the airflow direction without protruding at the air vent, reducing obstruction of the airflow and thus minimizing the impact on the exhaust volume and the rate of temperature regulation inside the vehicle. Furthermore, due to the concealed design of the vertical blades within the mounting housing, occupants can only see the knob at the air vent when adjusting the airflow direction, and the knob appears to float at the vent, giving the air vent a clean and aesthetically pleasing appearance.

[0027] 2. The inclined design of the sidewalls of the air guide duct can reduce the amount of material used in the manufacturing of the mounting housing while meeting the requirements for the rotation of the concealed vertical blades. At the same time, when the air conditioner is discharging air, the inner sidewall of the air guide duct can reduce the obstruction of the air conditioning air, making the airflow smoother. Furthermore, since the two inclined sidewalls of the air guide duct are inclined towards each other from the end closer to the mounting housing to the end farther away from the mounting housing, an air guide opening is formed at this point. After the air conditioning air enters the air guide duct, the air force will be concentrated under the guidance of the two inclined sidewalls, thereby making the air force blowing out of the air guide duct greater.

[0028] 3. After the rotating groove is fastened to the outer wall of the mounting ring, it can cover the mounting ring, so that the people inside the vehicle cannot see the mounting ring. The setting of the clearance opening allows one end of the rotating groove to pass through the clearance opening to cover the connecting plate, so that the people inside the vehicle cannot see the connecting plate. This reduces the visibility of the mounting base and its auxiliary structures at the air vent, making the presence of the dial button at the air vent more isolated and improving the floating effect of the dial button at the air vent.

[0035] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0036] This application discloses a concealed air outlet. (Refer to...) Figure 1The concealed air vent includes a mounting housing 1. One side wall of the mounting housing 1 has an integrally formed air guide groove 11. An exhaust port 12 is formed on the side wall of the air guide groove 11 away from the mounting housing 1. The two side walls of the air guide groove 11 are inclined, with the inclined side walls facing each other from the end closer to the mounting housing 1 to the end farther away from the mounting housing 1. A cover plate 14 is fixedly connected to the end of the air guide groove 11 away from the mounting housing 1. An opening is formed through the center of the cover plate, aligned with the exhaust port 12. When installing this concealed air vent, moving the cover plate 14 causes the mounting housing 1 and the air guide groove 11 to pass through pre-drilled mounting holes on the car's center console panel. Simultaneously, the cover plate 14 is fixedly connected to the car's center console panel with screws, thus installing the mounting housing 1 inside the car's center console panel. The air guide groove 11 is also located inside the car's center console panel, making the exhaust port 12 flush with the car's center console panel.

[0037] Reference Figure 2 Two hidden vertical blades 2 are rotatably connected to the inner wall of the air guide 11 via a rotating shaft. The two hidden vertical blades 2 are arranged along the length of the exhaust port 12 and are located on the inner wall of the air guide 11 near the exhaust port 12. A hidden horizontal blade 13 is also rotatably connected inside the mounting housing 1. The hidden horizontal blade 13 is located on the side of the hidden vertical blades 2 away from the exhaust port 12 and is arranged perpendicular to the hidden vertical blades 2.

[0038] Reference Figure 2 and Figure 3 An installation base 3 is fixedly connected to the outer wall of the air guide 11. One end of the installation base 3 passes through the wall of the air guide 11 and extends into the exhaust port 12. A connecting plate 33 is integrally formed at the end of the installation base 3 located inside the exhaust port 12. The connecting plate 33 is an arc-shaped plate and is located on the side of the installation base 3 closer to the inside of the installation housing 1. An installation ring 31 is integrally formed at the end of the connecting plate 33 away from the installation base 3.

[0039] Reference Figure 1 , Figure 2 and Figure 3 A knob 4 is installed inside the exhaust vent 12. One end of the knob 4 passes through the exhaust vent 12 and connects to the mounting ring 31, while the other end of the knob 4 extends out from the outer wall of the air guide groove 11 through the exhaust vent 12. A rotating groove 43 is integrally formed at the end of the knob 4 near the mounting ring 31. The side wall of the rotating groove 43 away from the knob 4 is open, and a clearance opening 32 is provided on the mounting base 3. A rotating shaft 42 is coaxially arranged inside the rotating groove 43. Both ends of the rotating shaft 42 can be fixedly connected to the connecting covers at both ends of the rotating groove 43. The rotating shaft 42 is inserted into the mounting ring 31, and the rotating groove 43 is fastened to the outer wall of the mounting ring 31. At the same time, one end of the rotating groove 43 passes through the clearance opening. The curvature of the outer wall of the rotating groove 43 is the same as the curvature of the connecting plate 33.

[0040] Reference Figure 3 Two connecting seats are connected to the side of the rotating groove 43 away from the knob 4. The two connecting seats are located at both ends of the rotating groove 43. A rotating shaft is fixedly connected between the two connecting seats. A fork connecting rod 41 is rotatably connected to the rotating shaft. An elastic snap fastener 411 is integrally formed at the end of the fork connecting rod 41 away from the rotating shaft. An installation port 24 is opened through the side wall of one of the hidden vertical blades 2. A connecting post 241 is integrally formed on the inner side wall of the installation port 24. The elastic snap fastener 411 is fastened to the connecting post 241. The inner side wall of the elastic snap fastener 411 is adapted to the outer side wall of the connecting post 241. The opening width of the elastic snap fastener 411 is smaller than the diameter of the inner side wall of the elastic snap fastener 411. The elastic snap fastener 411 and the connecting post 241 can rotate relative to each other.

[0041] Reference Figure 4 Both of the two hidden vertical blades 2 have an integrally formed connecting shaft 21 at the same end. The connecting shaft 21 passes through the wall of the air guide groove 11 and extends out from the outer wall of the air guide groove 11. The two connecting shafts 21 are fixedly connected to the same end by adhesive with a rotating piece 211. The two rotating pieces 211 are arranged in parallel and are located outside the air guide groove 11. The same hidden connecting rod 212 is rotatably connected to the two rotating pieces 211 by a rotating shaft.

[0042] When the air conditioning needs to be adjusted, the occupants can turn the knob 4. The knob 4 causes the rotating groove 43 to rotate around the mounting ring 31, and at the same time, it causes the rotating shaft 42 to rotate within the mounting ring 31. The rotating groove 43 drives the shift fork connecting rod 41 to move within the mounting housing 1 through the mounting seat. At the same time, the shift fork connecting rod 41 rotates relative to the knob 4. The movement of the shift fork connecting rod 41 can further drive one of the hidden vertical blades 2 to rotate. The rotation of the hidden vertical blade 2 drives the corresponding connecting shaft 21 to rotate, which in turn drives the corresponding rotating piece 211 to rotate. When the rotating piece 211 rotates, it can drive the hidden connecting rod 212 to move. The movement of the hidden connecting rod 212 drives the other rotating piece 211 to rotate, which drives the other connecting shaft 21 to rotate, thereby driving the other hidden vertical blade 2 to rotate. This achieves the synchronous rotation of the two hidden vertical blades 2. After the hidden vertical blades 2 rotate, they form an angled exhaust duct at the exhaust port 12. When the air conditioning air in the vehicle is discharged from the exhaust port 12, it passes between several hidden vertical blades 2. Under the tilting guidance of the hidden vertical blades 2, the original airflow direction is changed, thus realizing the adjustment of the air conditioning airflow direction.

[0043] Reference Figure 2 and Figure 3A toggle damper 431, made of flexible rubber, is provided on the inner wall of the rotating groove 43. The toggle damper 431 is embedded in a pre-drilled groove on the inner wall of the rotating groove 43, with the end of the toggle damper 431 away from the connection point abutting against the outer wall of the mounting ring 31. When the toggle button 4 is turned, causing the hidden vertical blade 2 to rotate, the toggle button 4 can simultaneously drive the rotating groove 43, causing the toggle damper 431 to slide on the outer wall of the mounting ring 31. After the toggle button 4 is turned, causing the hidden vertical blade 2 to rotate to the desired position, the operator removes the pushing force on the toggle button 4. At this time, the rotating groove 43 also stops rotating, and the toggle damper 431 stops sliding on the outer wall of the mounting ring 31. Because the toggle damper 431 and the mounting ring 31 are in contact, the toggle damper 431 and the mounting ring 31 are in contact with each other. The outer walls abut against each other, creating static friction between the outer walls and the mounting ring 31. This hinders the further movement of the toggle damper 431, preventing the toggle 4 from rotating under its own weight and causing the rotating groove 43 to rotate. This further fixes the position of the hidden vertical blade 2 after the rotation angle is adjusted. At the same time, since the toggle damper 431 is made of flexible rubber, it will deform under pressure between the inner wall of the rotating groove 43 and the outer wall of the mounting ring 31. This increases the contact area between the toggle damper 431 and the outer wall of the mounting ring 31, thereby increasing the static friction between the toggle damper 431 and the outer wall of the mounting ring 31, further improving the stability of fixing the position of the hidden vertical blade 2.

[0044] Reference Figure 2 and Figure 3 An adjusting fork 44 is also connected to the mounting base of the rotating groove 43 by screws. An adjusting rod is connected to one of the hidden horizontal blades 13. The rotation connection point of the hidden horizontal blade 13 is located in the middle of the two ends of the hidden horizontal blade 13. The same synchronizing rod 131 is rotatably connected to the same side of the lower end of the hidden horizontal blades 13.

[0045] The occupants can move the movable knob 4 along the length of the exhaust vent 12, which drives the adjustment fork 44 to move the adjustment lever. The movement of the adjustment lever can cause the upper end of the corresponding hidden horizontal blade 13 to rotate. The lower end of the hidden horizontal blade 13 rotates synchronously, which in turn causes the synchronizing rod 131 to move. The synchronizing rod 131 can then drive the remaining hidden horizontal blades 13 to rotate synchronously, thereby allowing the air conditioning to be adjusted to another direction.

[0046] Reference Figure 5 Several connecting strips 22 are glued to the side wall of the hidden vertical blade 2. The connecting strips 22 are divided into two groups and located at both ends of the hidden vertical blade 2. Insertion grooves 221 are opened on both sides of the connecting strips 22. One end of the insertion groove 221 is closed and the other end of the insertion groove 221 is connected to the end wall of the corresponding connecting strip 22.

[0047] Reference Figure 5A support plate 232 is provided between two adjacent connecting strips 22. The support plate 232 has integrally formed plug rods 231 on both sides. The plug rods 231 on both sides of the support plate 232 are respectively inserted into the corresponding plug grooves 221 of the connecting strips 22 on both sides. The side wall of the support plate 232 can be fixedly connected to the absorbent cotton layer 23 by Velcro.

[0048] When the temperature is high, if a car is placed in direct sunlight, the interior temperature will rise, which will also raise the temperature of the concealed vertical blades 2. In this case, the driver needs to turn on the air conditioner to cool the interior before entering the car. When the cold air blows out from the air vents, it will come into contact with the concealed vertical blades 2. Because the concealed vertical blades 2 are hot, the cold air will liquefy upon contact with the blades, forming water droplets on the surface of the concealed blades. If the air conditioner is blowing strongly, the water droplets will be blown away and fall into the car. At the same time, some water droplets can also flow along the concealed vertical blades 2 into the mounting housing 1 and further intrude into the air conditioner, causing damage to the air conditioner.

[0049] Therefore, before installing the hidden vertical blade 2, the operator can fix the absorbent cotton layer 23 on the side wall of the support plate 232, then hold the support plate 232 to align the two plug rods 231 with the corresponding plug slots 221, and then move the support plate 232 to insert the two plug rods 231 directly into the plug slots 221, thus realizing the installation of the absorbent cotton layer 23 on the side wall of the hidden vertical blade 2.

[0050] When the air conditioner is turned on in hot weather, the water droplets formed on the hidden vertical blades 2 will be absorbed by the water-absorbing cotton layer 23 on the side wall of the hidden vertical blades 2, reducing the accumulation of water droplets on the side wall of the hidden vertical blades 2. This reduces the situation where the air conditioner blows the water droplets away and they drift into the car with the wind due to the strong air conditioning force. At the same time, it reduces the situation where water droplets flow along the hidden vertical blades 2 into the mounting housing 1 and further invade the air conditioner, causing damage to the air conditioner.

[0051] The implementation principle of a concealed air outlet in this application embodiment is as follows:

[0052] When the air conditioning needs to be adjusted, the occupants can turn the knob 4. The knob 4 causes the rotating groove 43 to rotate around the mounting ring 31, and at the same time, it causes the rotating shaft 42 to rotate within the mounting ring 31. The rotating groove 43 drives the shift fork connecting rod 41 to move within the mounting housing 1 through the mounting seat. At the same time, the shift fork connecting rod 41 rotates relative to the knob 4. The movement of the shift fork connecting rod 41 can further drive one of the hidden vertical blades 2 to rotate. The rotation of the hidden vertical blade 2 drives the corresponding connecting shaft 21 to rotate, which in turn drives the corresponding rotating piece 211 to rotate. When the rotating piece 211 rotates, it can drive the hidden connecting rod 212 to move. The movement of the hidden connecting rod 212 drives the other rotating piece 211 to rotate, which drives the other connecting shaft 21 to rotate, thereby driving the other hidden vertical blade 2 to rotate. This achieves the synchronous rotation of the two hidden vertical blades 2.

[0053] Passengers inside the vehicle can also move the dial 4 along the length of the exhaust vent 12, causing the adjustment fork 44 to move the adjustment lever. The movement of the adjustment lever can cause the upper end of the corresponding hidden horizontal blade 13 to rotate, and the lower end of the hidden horizontal blade 13 to rotate synchronously. This, in turn, causes the synchronizing rod 131 to move synchronously. The synchronizing rod 131 can then drive the remaining hidden horizontal blades 13 to rotate synchronously, thereby allowing the air conditioning to be adjusted to another direction.

[0054] After the hidden vertical blade 2 (or hidden horizontal blade 13) rotates, an inclined air duct is formed inside the housing. When the air conditioning air in the vehicle is discharged from the air outlet 12, it passes between several hidden vertical blades 2 (or hidden horizontal blades 13). Under the inclined guidance of the hidden vertical blades 2 (or hidden horizontal blades 13), the original air direction is changed, thus realizing the adjustment of the air conditioning air direction.

[0055] Because the concealed vertical blades 2 and 13 are located on the inner wall of the mounting housing 1 and connected near the exhaust vent 12, they can adjust the airflow direction without protruding at the exhaust vent 12, reducing obstruction of the airflow from the exhaust vent 12 and thus minimizing the impact on the exhaust volume and the rate of temperature regulation inside the vehicle. Furthermore, due to their concealed placement within the mounting housing 1, occupants can only see the knob 4 at the exhaust vent 12 when adjusting the airflow direction. The knob appears to float at the exhaust vent 12, giving it a clean and aesthetically pleasing appearance.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
