Description

Technical Field

[0001] This utility model belongs to the field of dual-channel air outlets, specifically relating to a dual-channel air outlet structure that combines non-sensory airflow and normal airflow sweeping functions. Background Technology

[0002] Currently, vehicle air conditioning vents generally require manual adjustment knobs to regulate ventilation volume and direction. The disadvantages are that they can easily distract the driver and pose certain safety hazards. In terms of appearance, since there are many manually operated parts that are all exposed, it affects the aesthetics and also presents the problem of protruding parts inside the vehicle, which may cause unnecessary injury to passengers in the event of a collision. There are also motor-driven blades to achieve automatic adjustment, but their traditional motor control structure is more complex, has higher manufacturing costs, and poor mechanical durability.

[0003] To address this, a publicly disclosed Chinese utility model patent application (publication number: CN113085491A) discloses an in-vehicle automatic air vent adjustment device and a vehicle, comprising: a housing having a first air outlet and a second air outlet formed on both sides of its upper end; a front damper mechanism disposed in the upper half of the housing, capable of controlling the air outlet direction of the first and second air outlets; and a rear damper mechanism disposed in the lower half of the housing, capable of controlling the opening and closing of the first and second air outlets. Compared with the prior art, the advantage of this structure is that it achieves the air conditioning air venting function by directly driving a completely hidden blade with a stepper motor. This novel mechanism improves the aesthetics of the vehicle interior, eliminates the operating parts of conventional air vents, solves the problem of protrusions, reduces the need for passengers to manually adjust the air conditioning, improves passenger comfort and safety, and enhances reliability.

[0004] However, this air vent adjustment device uses two motors to adjust the air direction, which increases manufacturing costs and occupies a large amount of interior space. On the other hand, the air outlet has a relatively simple air outlet method and cannot be compatible with the non-intrusive airflow function on the basis of the dual-channel air outlet structure, which affects the user experience and reduces comfort. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a dual-channel air outlet structure that is simple in structure, has good stability, and can achieve different blowing effects under the same actuator, while also possessing both imperceptible wind and normal air sweeping functions.

[0006] The objective of this utility model can be achieved by addressing the following technical problem: proposing a dual-channel air outlet structure that combines both non-intrusive airflow and normal airflow functions, having at least an upper limit blowing state, a lower limit blowing state, a main blowing state, and a non-intrusive airflow state. The dual-channel air outlet structure includes:

[0007] The shell has a first air guide channel, a non-intrusive air guide channel and a second air guide channel formed sequentially along its thickness direction. The first air guide channel, the second air guide channel and the non-intrusive air guide channel are connected on the same side to form an air inlet channel.

[0008] A non-sensitive airflow panel is installed inside the housing, and the non-sensitive airflow panel is located at the end of the non-sensitive airflow channel away from the air inlet channel;

[0009] The damper assembly and the air guide assembly are rotatably disposed within the housing and used to control the opening or closing of the first air guide channel, the second air guide channel, and the non-sensitive air channel; the air guide assembly is rotatably disposed within the air inlet duct and used to control any one of the first air guide channel, the first air guide channel, and the non-sensitive air channel to communicate with the air inlet duct.

[0010] A drive disc is rotatably disposed on the outside of the housing. The drive disc is provided with a first track groove, a second track groove, and a third track groove. The first track groove and the second track groove are used to drive the damper assembly to rotate within the housing, so as to realize the synchronous opening or closing of the first air guide channel and the second air guide channel. The third track groove is used to drive the air guide assembly to rotate within the air inlet duct.

[0011] When the drive disc rotates in one direction, it is used to drive the dual-channel air outlet structure to switch sequentially from the upper limit blowing state to the main blowing state, the lower limit blowing state, and the windless state, or to drive the dual-channel air outlet structure to switch sequentially from the windless state to the lower limit blowing state, the main blowing state, and the upper limit blowing state.

[0012] In the above-mentioned dual-channel air outlet structure that combines non-sensory wind and normal air sweeping functions, the end of the damper assembly is provided with a first connector, the center line of the first connector coincides with the rotation center line of the damper assembly, the first connector is provided with a first traction column, the center line of the first traction column is arranged parallel to the center line of the first connector, and the first traction column is movably engaged in both the first track groove and the second track groove.

[0013] In the above-mentioned dual-channel air outlet structure that combines non-sensory airflow and normal airflow functions, the non-sensory airflow panel is formed by a top plate, a ventilation plate, and a bottom plate. Several mesh openings are arranged in an array on the ventilation plate. The top plate and the bottom plate are set at an angle to guide the gas in the non-sensory airflow channel to the mesh openings.

[0014] In the aforementioned dual-channel air outlet structure that combines both non-sensory airflow and normal airflow functions, both the top plate and the bottom plate have extension plates extending outward along their width direction. Several positioning blocks are evenly distributed at the ends of the extension plates. Mounting plates are formed at both ends of the ventilation plate. Locking holes are provided on the mounting plates. Positioning grooves and locking pins are formed on the housing. The positioning blocks are movably inserted into the positioning grooves, so that the locking pins pass through the locking holes to restrict the movement of the non-sensory airflow panel relative to the housing.

[0015] In the above-mentioned dual-channel air outlet structure that combines non-sensory wind and normal air sweeping functions, the end of the air guiding component is provided with a second connector. The center line of the second connector coincides with the rotation center line of the air guiding component. A second traction column is provided on the second connector. The center line of the second traction column is parallel to the center line of the second connector. The second traction column is inserted into a third track groove, and the outer wall of the second traction column is movably abutting against the inner wall of the third track groove.

[0016] In the aforementioned dual-channel air outlet structure that combines both sensorless airflow and normal airflow sweeping functions, both the first and second trajectory slots have an arc segment and a pushing segment, wherein:

[0017] The center of the arc segment coincides with the center of the drive disc, so that the first traction column within the arc segment remains stationary, thereby achieving the closure of the sensorless air passage.

[0018] The pushing section is connected to the arc section, and the pushing section and the arc section are both arranged opposite to each other on the drive disk, so as to realize that while the sensorless air duct is opened, the first air guide channel and the second air guide channel are closed simultaneously.

[0019] In the above-mentioned dual-channel air outlet structure that combines non-sensory wind and normal air sweeping functions, the third trajectory groove includes a traction section and a rotation section that are interconnected. When the second traction column is in the traction section, it drives the air guide component to swing back and forth in the air inlet duct. When the second traction column enters the rotation section from the traction section, it causes the air guide component to gradually swing to the middle position of the air inlet duct.

[0020] In the aforementioned dual-channel air outlet structure that combines both non-sensory airflow and normal airflow functions, the damper assembly includes:

[0021] Two sealing plates, one of which is rotatably disposed between the first air guide channel and the air inlet channel, and the other of which is rotatably disposed between the second air guide channel and the air inlet channel, and the sealing plates are movable against the inner sidewall of the housing;

[0026] An air guide plate is connected to the second rotating shaft and is integrally formed with the second rotating shaft or is separately set. The air guide plate is movable and abuts against the side wall of the air inlet duct.

[0027] In the aforementioned dual-channel air outlet structure that combines both non-sensory wind and normal air sweeping functions, a driving component and several oscillating blades are also included. The driving component is disposed outside the housing. Several oscillating blades are installed in both the first and second air guide channels. The several oscillating blades are connected to each other by a connecting plate. The oscillating blades in the first and second air guide channels are connected by a connecting column. The output shaft of the driving component is connected to any one of the oscillating blades to achieve synchronous oscillation of several oscillating blades and change the gas flow direction.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] (1) The present invention provides a dual-channel air outlet structure that combines non-sensory airflow and normal airflow functions. Through the rotation of a drive disc and the use of a non-sensory airflow panel, it realizes the integrated design of multiple air supply modes. This reduces the use of motors, lowers the vehicle interior space occupied by the dual-channel air outlet structure and manufacturing costs, and at the same time achieves the comfort effect of non-sensory airflow on the dual-channel air outlet, meeting the user's dual needs for comfort and wide-area airflow, and improving the user's user experience.

[0030] (2) The positioning groove and locking hole form a double limiting structure, which effectively prevents the air-free panel from loosening or shifting during operation, improves the stability of the overall structure, and ensures the air supply quality and efficiency in the air-free mode.

[0031] (3) The design of the arc segment and the push segment enables the free switching between the upper limit blowing state, the lower limit blowing state and the main blowing state by using the air guide plate when the first and second air guide channels are opened simultaneously. When the first and second air guide channels are closed simultaneously, the air guide plate is used to achieve the switching of the imperceptible wind state. The airflows do not interfere with each other, which improves the smoothness of the blowing state switching and the user experience. Attached Figure Description

[0049] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0050] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0051] Example 1:

[0052] like Figures 1 to 11As shown, this utility model discloses a dual-channel air outlet structure that combines non-intrusive airflow and normal sweeping functions. It has at least an upper limit blowing state, a lower limit blowing state, a main blowing state, and a non-intrusive airflow state. The dual-channel air outlet structure includes: a housing 1, with a first air guide channel 10, a non-intrusive airflow channel 12, and a second air guide channel 11 sequentially formed along its thickness direction. The first air guide channel 10, the second air guide channel 11, and the non-intrusive airflow channel 12 are connected on the same side to form an air inlet duct 13; a non-intrusive airflow panel 2, installed inside the housing 1, located at the end of the non-intrusive airflow channel 12 away from the air inlet duct 13; a damper assembly 3 and a guide assembly 4. The damper assembly 3 is rotatably disposed inside the housing 1 and is used to control the opening or closing of the first air guide channel 10, the second air guide channel 11, and the non-intrusive airflow channel 12; the guide assembly 4 is rotatably disposed inside the air inlet duct 13 and is used to... The system controls any one of the first air guide channel 10, the first air guide channel 11, and the non-sensitive air channel 12 to connect with the air inlet duct 13; the drive disk 5 is rotatably disposed on the outside of the housing 1, and the drive disk 5 is provided with a first track groove 50, a second track groove 51, and a third track groove 53. The first track groove 50 and the second track groove 51 are used to drive the damper assembly 3 to rotate within the housing 1, so as to realize the synchronous opening or closing of the first air guide channel 10 and the second air guide channel 11; the third track groove 53 is used to drive the air guide assembly 4 to rotate within the air inlet duct 13; when the drive disk 5 rotates in one direction, it is used to drive the dual-channel air outlet structure to switch sequentially from the upper limit blowing state to the main blowing state, the lower limit blowing state, and the non-sensitive air state, or to drive the dual-channel air outlet structure to switch sequentially from the non-sensitive air state to the lower limit blowing state, the main blowing state, and the upper limit blowing state.

[0053] In this embodiment, the air inlet duct 13 is used to connect to the vehicle air conditioner and guide the air blown out by the vehicle air conditioner into the housing 1. The rotation of the drive disc 5 can be achieved by a motor 18 (stepper motor or servo motor) installed on the housing 1. Specifically, this embodiment adds a sensorless air duct 12 and a sensorless air panel 2 to the dual-channel air outlet structure. Under normal use, the sensorless air duct 12 is closed under the action of the damper assembly 3 (see reference). Figure 6 (That is, both the first air guide channel 10 and the second air guide channel 11 are in the open state), as the drive disc 5 moves along Figure 5 Rotating clockwise, the first and second track grooves 50 and 51 do not cause the damper assembly 3 to move due to the rotation of the drive disc 5; only the air guide assembly 4 moves due to the movement of the third track groove 53. Figure 6 The lower limit blowing state shown is switched to Figure 7 In the main blowing state shown, similarly, when the drive disc 5 continues to rotate in the same direction, the damper assembly 3 will still not move (i.e., it will still be closed to the sensorless air passage 12). At this time, the air guide assembly 4 is moved by the movement of the third track groove 53. Figure 7 switching from the main blowing state shown in Figure 8 to the lower limit blowing state shown in, until the driving disc 5 rotates further (still in the same rotation direction as described above). At this time, under the combined action of the first track groove 50 and the second track groove 51, the damper assembly 3 is pushed from Figure 8 the position shown in synchronously switches to Figure 2 the position shown in. That is, the non-inductive air channel 12 is opened at this time, and both the first air guide channel 10 and the second air guide channel 11 are switched from the open state to the closed state. In this process, the third track groove 53 synchronously pushes the air guide assembly 4 from Figure 8 the position shown in rotates back to Figure 2 the position shown in (i.e., located at the middle position of the ventilation duct). At this time, the air blown by the vehicle air conditioner can pass through the non-inductive air channel 12 and blow to the angle required by the user through the non-inductive air panel 2. The reverse is also true: when the driving disc 5 rotates in the opposite direction to the above direction, the dual-channel damper structure can be sequentially switched from the non-inductive air state to the lower limit blowing state, the main blowing state and the upper limit blowing state. It can be seen that in the present utility model, by arranging the first air guide channel 10, the non-inductive air channel 12 and the second air guide channel 11 in the housing 1, and making the three share one air inlet duct 13, the integrated design of various air supply modes is realized. That is, the damper assembly 3 is used to control the opening and closing of each channel, so that the air guide assembly 4 can selectively communicate the air inlet duct 13 with a certain channel, and cooperate with the multi-track grooves on the driving disc 5 to realize linkage control. The four states of upper limit blowing, main blowing, lower limit blowing and non-inductive air can be switched sequentially when the driving disc 5 rotates continuously in one direction, which avoids complex control logic and multiple independent driving mechanisms, significantly simplifies the structure, reduces the cost, and improves the reliability. Meanwhile, the "non-inductive air" function and the traditional air sweeping function are integrated in the same air outlet structure, which satisfies users' dual requirements for comfort and wide-area air supply, and improves user experience.

[0054] The non-inductive air panel 2 is enclosed by a top plate 20, an air permeable plate 21 and a bottom plate 22. A plurality of mesh openings 210 are distributed in an array on the air permeable plate 21. The top plate 20 and the bottom plate 22 are arranged at an included angle to guide the gas in the non-inductive air channel 12 to the mesh openings 210.

[0055] As shown in Figures 1 to 3 , when the dual-channel air outlet structure is switched to the non-inductive air state, the driving disc 5 drives the air guide assembly 4 through the third track groove 53 to communicate the air inlet duct 13 with the non-inductive air channel 12, and at the same time the damper assembly 3 closes the first air guide channel 10 and the second air guide channel 11, so that all the airflow is guided into the non-inductive air channel 12, and then enters the internal cavity jointly enclosed by the top plate 20, the bottom plate 22 and the air permeable plate 21; since the top plate 20 and the bottom plate 22 are arranged at an included angle (as shown in Figure 3The stepped structure shown in the diagram guides the airflow within the cavity through the top plate 20 and bottom plate 22, forcing it to converge towards the ventilation plate 21. The ventilation plate 21 features a high-density, micro-sized mesh array 210 (such as micropores or slits), ensuring that the airflow, under static pressure, is ejected at low speed, from multiple points, and evenly through these densely distributed mesh openings (forming a gentle, "curtain-like" airflow), achieving comfortable airflow without a direct blowing sensation. This design of the air-permeable panel 2 reduces perceived wind speed and avoids discomfort from direct blowing. It not only enhances comfort but also improves airflow diffusion through structural optimization, achieving gentle airflow without requiring additional fan power, thus saving energy and being environmentally friendly. The overall structure is compact and has high space utilization.

[0056] Both the top plate 20 and the bottom plate 22 have extension plates 200 extending outward along their width direction. Several positioning blocks 200a are evenly distributed at the ends of the extension plates 200. Mounting plates 211 are formed at both ends of the ventilation plate 21. Locking holes 211a are provided on the mounting plates 211. Positioning grooves 14 and locking pins 15 are formed on the housing 1. The positioning blocks 200a are movably inserted into the positioning grooves 14, so that the locking pins 15 pass through the locking holes 211a to restrict the movement of the air-sensing panel 2 relative to the housing 1.

[0057] Continue to refer to Figures 1 to 3 As shown in the structure, in this embodiment, the top plate 20 and the extension plate 200 on the outer side of the bottom plate 22 of the windless panel 2 are provided with positioning blocks 200a. During the installation process, the positioning blocks 200a are first aligned with the corresponding positioning groove 14 entrance on the housing 1. Since the positioning blocks 200a are evenly distributed and the positioning groove 14 is a bayonet structure, the two form a guiding fit to guide the panel to slide in smoothly. When the windless panel 2 is fully pushed into the predetermined position, the locking hole 211a on the mounting plate 211 is exactly aligned with the preset locking post 15 on the housing 1. The locking post 15 elastically or with interference passes through and is locked into the locking hole 211a to form a mechanical limit, preventing the panel from axially moving or falling off under the impact or vibration of airflow. As can be seen, this embodiment forms a double limiting structure through the positioning block 200a and the locking hole 211a, which effectively prevents the windless panel 2 from loosening or shifting during operation, improves the overall sealing and stability of the structure, prevents air leakage, and ensures the air supply quality and efficiency in the windless mode.

[0058] The damper assembly 3 is provided with a first connector 30 at its end. The center line of the first connector 30 coincides with the rotation center line of the damper assembly 3. A first traction column 300 is provided on the first connector 30. The center line of the first traction column 300 is parallel to the center line of the first connector 30. The first traction column 300 is movably engaged in both the first track groove 50 and the second track groove 51.

[0059] In this embodiment, two first connectors 30 and two first traction columns 300 are provided, and a set of first connectors 30 and first traction columns 300 are correspondingly connected to both the first track groove 50 and the second track groove 51, for realizing the connection between the damper assembly 3 and the first track groove 50 and the second track groove 51. Specifically, as shown... Figure 4 , Figure 5 as well as Figure 9 and Figure 10 It can be seen that the first traction column 300 is located at the starting position of the first track groove 50 and the second track groove 51, pushing the first connecting piece 30 to drive the damper assembly 3 to synchronously open or close the first air guide channel 10 and the second air guide channel 11, ensuring that the damper assembly 3 is precisely controlled by the drive disc 5 and moves synchronously, avoiding airflow leakage or disordered air delivery direction caused by asynchronous actions, improving control accuracy and system stability. In addition, the connection structure is simple and reliable, easy to assemble and maintain, and conducive to mass production.

[0060] The end of the air guide assembly 4 is provided with a second connector 40. The center line of the second connector 40 coincides with the rotation center line of the air guide assembly 4. A second traction column 400 is provided on the second connector 40. The center line of the second traction column 400 is parallel to the center line of the second connector 40. The second traction column 400 is inserted into the third track groove 53, and the outer wall of the second traction column 400 is movable against the inner wall of the third track groove 53.

[0061] Similarly, such as Figure 4 , Figure 5 as well as Figure 9 and Figure 10 It can be seen that the air guide assembly 4 cooperates with the third track groove 53 of the drive disk 5 through the second traction column 400 on the second connector 40 to achieve precise rotation control of the air guide assembly 4 in the air inlet duct 13. Since the center line of the second traction column 400 is parallel to the rotation center line and moves against the inner wall of the track groove, it can smoothly transmit power during the rotation of the drive disk 5, reducing jamming and wear. This structure realizes that the air guide assembly 4 and the damper assembly 3 share a drive disk 5 but complete an independent and coordinated air control method, ensuring that the air inlet duct 13 is only connected to the target channel, improving the accuracy of airflow guidance, and ensuring the smoothness and sealing of switching between different air supply modes.

[0062] Both the first track groove 50 and the second track groove 51 have an arc segment 520 and a push segment 521, wherein: the center of the arc segment 520 coincides with the center of the drive disk 5, so that the first traction column 300 located in the arc segment 520 remains stationary, thereby achieving the closure of the sensorless air passage 12; the push segment 521 is connected to the arc segment 520, and the push segment 521 and the arc segment 520 are both arranged opposite to each other on the drive disk 5, so as to achieve the simultaneous closure of the first air guide passage 10 and the second air guide passage 11 while the sensorless air passage is opened.

[0063] like Figure 2 and Figure 3 As shown, since the center of the arc segment 520 coincides with the rotation center of the drive disk 5, when the drive disk 5 continues to rotate, the groove wall of the arc segment 520 does not generate radial thrust, so that the first traction column 300 can rotate around the center with the drive disk 5 within the arc segment 520 without being subjected to lateral force, and therefore will not push the damper assembly 3 to rotate; as the drive disk 5 continues to rotate, the first traction column 300 can slide from the arc segment 520 into the push segment 521. Since the push segment 521 is a non-concentric structure (i.e., its curvature center is offset from the center of the drive disk 5), when the drive disk 5 continues to rotate, the groove wall of the push segment 521 will apply radial or tangential thrust to the first traction column 300. This force is transmitted to the damper assembly 3 through the first traction column 300, driving it to rotate around its own rotation center. Finally, under the action of the push segment 521, the damper assembly 3 is driven to complete the synchronous opening and closing of the first air guide channel 10 and the second air guide channel 11 (i.e., the opening of the sensorless air channel 12 is achieved in the closed state). This trajectory design implements an interlock function during critical mode switching, ensuring that the non-intrusive wind mode and other blowing modes will not be activated simultaneously, avoiding airflow interference and improving safety and the rationality of control logic.

[0064] The third track groove 53 includes a traction section 530 and a rotation section 531 that are interconnected. When the second traction column 400 is in the traction section 530, it drives the air guide assembly 4 to swing back and forth in the air inlet duct 13. When the second traction column 400 enters the rotation section 531 from the traction section 530, it causes the air guide assembly 4 to gradually swing to the middle position of the air inlet duct 13.

[0065] like Figure 2 and Figure 3 As shown, when the drive disc 5 rotates in the same direction, the two first traction columns 300 on the damper assembly 3 move within the aforementioned arc segment 520. At this time, the damper assembly 3 achieves continuous closure of the sensorless air passage 12 (i.e., both the first air guide passage 10 and the second air guide passage 11 are in the open state, see reference). Figures 6-8 During this process, the second traction column 400 controls the connection state between the air inlet duct 13 and the first air guide duct 10 and / or the second air guide duct 11 or the sensorless air guide duct 12 due to the rotation of the drive disc 5 (see reference). Figures 6 to 8 (as shown in the diagram), until the second traction column 400 slides from the traction section 530 into the rotation section 531, the aforementioned first traction column 300 slides from the arc section 520 into the pushing section 521, that is, when the air guide assembly 4... Figure 8 The status shown has switched to Figure 2 During the process shown, the damper assembly 3 is synchronously controlled by... Figure 8 The closed state of the sensorless air duct 12 is shown to be switched to... Figure 2 As shown in the open state of the non-intrusive airflow channel 12, the air guide component 4 gradually rotates to the middle position of the air inlet duct 13, precisely aligning with the inlet of the non-intrusive airflow channel 12, ensuring efficient airflow into the non-intrusive airflow channel 12 in non-intrusive airflow mode. This trajectory design achieves a smooth transition from sweeping airflow to non-intrusive airflow, avoiding abrupt airflow changes, improving the naturalness of mode switching and user experience, while also optimizing aerodynamic performance.

[0066] Preferably, in this embodiment, the third track groove 53 may also be provided with a clearance section 532, which is connected between the traction section 530 and the rotation section 531. That is, the second traction column 400 passes through the clearance section 532 before the traction section 530. The clearance section 532 can provide sufficient space for the first traction column 300 to slide from the arc section 520 to the pushing section 521, avoiding positional interference between the two first traction columns 300 and the second traction column 400. On the other hand, it can ensure that the time for the second traction column 400 to slide from the clearance section 532 to the end position of the rotation section 531 is consistent with the time required for the damper assembly 3 to slide from the arc section 520 to the top position of the pushing section 521, thereby improving the accuracy and reliability of the dual-channel air outlet structure in switching between various states.

[0067] The damper assembly 3 includes: two sealing plates 31, one of which is rotatably disposed between the first air guide channel 10 and the air inlet channel 13, and the other sealing plate 31 is rotatably disposed between the second air guide channel 11 and the air inlet channel 13. The sealing plates 31 are movable against the inner side wall of the housing 1; a first rotating shaft 32 is rotatably disposed inside the housing 1, the sealing plates 31 are mounted on the first rotating shaft 32, and a first connecting piece 30 is snapped onto the first rotating shaft 32; a sealing block 33 is connected to the end of each sealing plate 31, and a sealing groove 330 is formed on the sealing block 33. The housing 1 is provided with a sealing frame 16 located between the non-intrusive air guide channel 12 and the air inlet channel 13. A limiting block 160 is symmetrically formed on the sealing frame 16, and the sealing groove 330 is movable against the limiting block 160.

[0068] like Figures 6 to 10As shown, in this embodiment, the damper assembly 3 uses two independent sealing plates 31 to control the opening and closing of the first air guide channel 10 and the second air guide channel 11 respectively, and both are driven by the first rotating shaft 32 (that is, each sealing plate 31 is connected to the first rotating shaft 32). As the first traction column 300 slides from the arc section 520 into the pushing section 521, the first traction column 300 in the pushing section 521 can drive the first connecting piece 30 to rotate due to the rotation of the driving disk 5, thereby driving the first rotating shaft 32 connected to it to rotate synchronously relative to the housing 1. Finally, the sealing plate 31 abuts against the sealing frame 16 or the inner wall of the housing 1, realizing the synchronous opening or closing of the first air guide channel 10 and the second air guide channel 11. It also greatly reduces the cross-flow and leakage between the channels, and improves the air supply efficiency and the clarity of mode switching. It should be noted that both the sealing block 33 and the limiting block 160 in this embodiment can be made of soft rubber. With the tight fit between the sealing groove 330 and the limiting block 160, air leakage is prevented, which would affect the user's experience.

[0069] It should be added that, in this embodiment, a snap-fit ​​groove 320 is provided on the first rotating shaft 32, and a snap-fit ​​block 301 is provided on the first connecting member 30. By extending the first connecting member 30 into the first rotating shaft 32, the snap-fit ​​block 301 can be snapped into the snap-fit ​​groove 320, realizing a stable connection between the first rotating shaft 32 and the first connecting member 30, and ensuring that the first rotating shaft 32 and the sealing plate 31 are rotated synchronously under the cooperation of the first traction column 300 and the pushing section 521. In addition, in this embodiment, an extension block 321 is formed on the outer wall of the first rotating shaft 32, and a limiting inclined surface 17 is formed in the housing 1. The extension block 321 moves against the limiting inclined surface 17, thereby ensuring that the sealing groove 330 on the sealing block 33 accurately overlaps and fits tightly on the limiting block 160, so as to ensure the accuracy and stability of the sealing plate 31 when sealing and closing the non-intrusive air passage 12.

[0070] The air guide assembly 4 includes: a second rotating shaft 41, which is rotatably disposed in the air inlet duct 13, and the end of the second rotating shaft 41 is provided with a mounting hole 42, and the second connecting piece 40 is interference-fitted with the mounting hole 42; and an air guide plate 43, which is connected to the second rotating shaft 41 and is integrally formed with the second rotating shaft 41 or separately disposed therefrom, and the air guide plate 43 is movable against the side wall of the air inlet duct 13.

[0071] like Figure 8 and Figure 9As shown, in this embodiment, the air guide plate 43 in the air guide assembly 4 is integrally formed with the second rotating shaft 41 or connected separately, which is flexible in structure and easy to manufacture and replace. The second rotating shaft 41 is interference-fitted with the second connecting piece 40 through the mounting hole 42, which is firmly connected and reliable in transmission, avoiding air guide angle deviation or action failure caused by loosening or slippage, and improving control accuracy and reliability. When the second traction column 400 is at the beginning and end of the traction section 530, the air guide plate 43 moves against the side wall of the air inlet duct 13, which can effectively guide the airflow direction and prevent the airflow from leaking from the edge. This design enhances the airflow organization capability in the air inlet duct 13, making the airflow more concentrated and the direction more controllable, and improving the air delivery distance and coverage, especially performing well in the main blowing and sweeping modes.

[0072] Example 2:

[0073] Based on the structure of Embodiment 1, Embodiment 2 further includes a driving component 60 and several oscillating blades 61. The driving component 60 is disposed outside the housing 1. Several oscillating blades 61 are installed in both the first air guide channel 10 and the second air guide channel 11. The several oscillating blades 61 are connected to each other by a connecting plate 62. The oscillating blades 61 in the first air guide channel 10 and the second air guide channel 11 are connected by a connecting column 63. The output shaft of the driving component 60 is connected to any one of the oscillating blades 61 to realize the synchronous oscillation of several oscillating blades 61 to change the gas flow direction.

[0074] like Figure 2 , Figures 6-8 as well as Figure 11 As shown, in this embodiment, several swing blades 61 are evenly arranged laterally in the first air guide channel 10 and the second air guide channel 11. Each swing blade 61 can swing around its own axis. In order to realize the synchronous swing operation of the swing blades 61 in the first air guide channel 10 and the second air guide channel 11, this embodiment uses a connecting column 63 to longitudinally traverse the non-intrusive air channel 12 along the thickness direction of the housing 1 to achieve cross-air duct linkage, saving the use of the driving component 60 and the connecting plate 62, and reducing the manufacturing cost of this dual-channel air outlet structure. As the connecting plate 62 and the connecting column 63 link the blades in the first air guide channel 10 and the second air guide channel 11, and the single driving component 60 controls all blades to swing synchronously, the sweeping function in each direction in the first / second air guide channel 11 can be realized. This structure ensures the consistency of the sweeping angle and the stability of operation. At the same time, the driving component 60 is placed outside the housing 1, which is convenient for maintenance and replacement, and improves the maintainability of the system. When used in combination with the main blowing state, it can realize large-area uniform air supply, and enhance the environmental adaptability and comfort of the air conditioner.

[0075] This embodiment uses an integrated drive disc to control the coordinated movement of the damper assembly 3 and the air guide assembly 4, achieving unidirectional continuous switching of four air outlet modes (upper limit airflow, main airflow, lower limit airflow, and sensorless airflow). Specifically, when the two sealing plates 31 work together to close the sensorless airflow channel 12, the air guide plate 43 can move due to the traction section 530 within the third trajectory groove 53. Figures 6 to 8 The switching between states continues until the second traction column 400 slides into the rotating section, at which point the first traction column 300 also slides into the pushing section 521, causing the two sealing plates 31 to rotate relative to the housing 1 and close the first air guide channel 10 and the second air guide channel 11 respectively. Simultaneously, the air guide plate 43... Figure 8 The status shown has switched to Figure 2 The state shown ensures that the airflow in the air inlet duct 13 completely enters the non-sensitive airflow channel 12 and is blown to the user's desired location through the array of distributed mesh openings 210. Therefore, the structure adopts a three-layer channel design (the first air guide channel 10, the non-sensitive airflow channel 12, and the second air guide channel 11 share the air inlet duct). Combined with the multi-track groove drive disk 2, the linkage damper, and the adjustable air guide plate 43, it realizes intelligent switching of multiple air supply modes through a single drive without adding an additional drive source. In particular, it solves the technical problem that traditional air conditioning vents cannot take into account both "powerful sweeping air" and "gentle non-sensitive air".

[0076] It should be noted that the driving component 60 in this embodiment can be replaced by other driving devices such as stepper motors and servo motors.
