Description

Technical Field

[0001] This utility model belongs to the field of air conditioner technology, specifically relating to an air outlet structure, an air conditioner, and an automobile. Background Technology

[0002] Traditional automotive air conditioning vents typically require manual adjustment of the airflow direction by moving blades. For example, moving one set of blades left or right controls lateral airflow, while moving another set up or down controls vertical airflow. This manual operation is not only cumbersome but also cannot automatically adjust to passenger needs. Although some improved designs attempt to replace manual operation with motors, these structures often only control lateral or vertical adjustment individually, requiring multiple motors and transmission components, resulting in a large footprint. For instance, to direct airflow to the upper left, the traditional solution requires operating the lateral and vertical adjustment mechanisms in two steps, which is cumbersome and difficult to synchronize precisely, leading to a poor user experience. Utility Model Content

[0003] In view of this, the present invention provides an air outlet structure, an air conditioner, and an automobile, which solves the technical problem that traditional air outlet structures can only control horizontal or vertical adjustment individually.

[0004] To address the aforementioned problems, according to one aspect of this application, an embodiment of the present invention provides an air outlet structure, the air outlet structure comprising a first adjustment unit, a second adjustment unit, a rotating ring, and an air outlet unit. The output end of the first adjustment unit passes through the rotating ring and can drive the rotating ring to rotate in a first direction. The output end of the second adjustment unit passes through the air outlet unit and the rotating ring, enabling the air outlet unit to follow the rotating ring to rotate in the first direction. Furthermore, the second adjustment unit can also drive the air outlet unit to rotate in a second direction.

[0005] In some embodiments, the air outlet unit includes an air outlet housing, a flow guiding module, a first blade, a second blade, and an opening adjustment module. The flow guiding module is disposed inside the air outlet housing. The first blade and the second blade are disposed at the opening of the air outlet housing. The opening adjustment module is connected to one end of the first blade and one end of the second blade and is used to adjust the angle between the other ends of the first blade and the other ends of the second blade.

[0006] In some embodiments, the opening adjustment module includes a third motor, a third shaft, a first bevel gear, a second bevel gear, and a third bevel gear. The output end of the third motor is connected to one end of the third shaft, and the other end of the third shaft is connected to the first bevel gear. The first bevel gear meshes with the second bevel gear, and the second bevel gear meshes with the third bevel gear. The first blade is connected to the first bevel gear, and the second blade is connected to the third bevel gear.

[0007] In some embodiments, the first adjustment unit includes a first motor and a first shaft, the output end of the first motor is connected to one end of the first shaft, and the other end of the first shaft is fixed to the rotating ring.

[0008] In some embodiments, the second adjustment unit includes a second motor and a second shaft, the output end of the second motor is connected to one end of the second shaft, and the other end of the second shaft is hinged to the air outlet unit through a hole in the air outlet housing.

[0009] In some embodiments, the air outlet structure further includes a housing, which is an annular structure with a notch, and the housing is arranged around the rotating ring; the output end of the first adjustment unit passes through the housing and is fixed to the rotating ring, and the output end of the second adjustment unit passes through the notch to connect the air outlet unit and the rotating ring.

[0010] In some embodiments, guide rails are provided on both sides of the notch, and a slider is provided on the second motor. The two sides of the slider cooperate with the guide rails so that the second motor can rotate along the first direction following the air outlet unit.

[0013] According to another aspect of this application, an embodiment of the present invention provides an automobile that includes the air conditioner described above.

[0014] Compared with the prior art, the air outlet structure of this utility model has at least the following beneficial effects:

[0015] The air outlet structure provided by this utility model includes a first adjustment unit, a second adjustment unit, a rotating ring, and an air outlet unit. The output end of the first adjustment unit passes through the rotating ring and can drive the rotating ring to rotate in a first direction. The output end of the second adjustment unit passes through the air outlet unit and the rotating ring, so that the air outlet unit can follow the rotating ring to rotate in the first direction. The second adjustment unit can also drive the air outlet unit to rotate in a second direction.

[0016] During lateral adjustment, the first adjustment unit drives the rotating ring to rotate around the lateral axis, causing the entire air outlet unit to swing left and right, thus deflecting the airflow direction. During longitudinal adjustment, the second adjustment unit directly drives the air outlet unit to rotate around the longitudinal axis, causing the airflow to deflect up and down. When oblique airflow is required, the first and second adjustment units work together: the rotating ring moves the air outlet unit laterally to the left, while the second adjustment unit drives the air outlet unit to rotate upwards; the combined effect achieves precise multi-dimensional adjustment. The lateral movement of the rotating ring and the longitudinal movement of the air outlet unit are independent and synchronous, avoiding the cumbersome nature of traditional step-by-step operations. The coordinated control of the first and second adjustment units replaces manual step-by-step operations, allowing users to achieve synchronous lateral and longitudinal adjustments with a single button press on the controller. The integrated design of the rotating ring and the air outlet unit reduces the space occupied by traditional multiple motors and transmission components, resulting in a more compact structure. The first adjustment unit directly drives the rotating ring to rotate laterally, and the second adjustment unit directly drives the air outlet unit to rotate longitudinally; the transmission path is short and there are no multi-stage gear engagements, reducing mechanical wear and error risks.

[0036] Example 1

[0037] This embodiment provides an air outlet structure, such as Figures 1-10 As shown, the air outlet structure includes a first adjustment unit 1, a second adjustment unit 2, a rotating ring 3, and an air outlet unit 4. The output end of the first adjustment unit 1 passes through the rotating ring 3 and can drive the rotating ring 3 to rotate in a first direction. The output end of the second adjustment unit 2 passes through the air outlet unit 4 and the rotating ring 3, so that the air outlet unit 4 can follow the rotating ring 3 to rotate in the first direction. The second adjustment unit 2 can also drive the air outlet unit 4 to rotate in a second direction.

[0038] Specifically, the output shaft of the first adjustment unit 1 passes vertically through the central axis of the rotating ring 3, forming the driving core of the rotating ring 3. The output shaft of the second adjustment unit 2 passes axially through the inner ring space of the air outlet unit 4 and the rotating ring 3, forming a nested transmission structure. The rotating ring 3 rotatably covers the outside of the air outlet unit 4, and the two form a coaxial linkage relationship through the output shaft of the second adjustment unit 2. At the same time, the air outlet unit 4 itself can be axially deflected relative to the rotating ring 3.

[0039] The first adjustment unit 1 drives the rotating ring 3 to rotate laterally, thereby adjusting the overall left-right (lateral) direction of the air outlet. The second adjustment unit 2 directly drives the air outlet unit 4 to rotate longitudinally, controlling the vertical (vertical) deflection of the airflow. The rotating ring 3, as a transmission component for lateral movement, transmits the power of the first adjustment unit 1 to the air outlet unit 4, while also supporting the installation of the second adjustment unit 2. The air outlet unit 4 is the core control component for airflow direction, achieving multi-dimensional airflow direction adjustment through a combination of lateral and longitudinal movements, such as precise airflow to the upper left or lower right.

[0040] During horizontal adjustment, the first adjustment unit 1 drives the rotating ring 3 to rotate around the horizontal axis, and the rotating ring 3 causes the air outlet unit 4 to swing left and right, thus deflecting the airflow direction left and right. During vertical adjustment, the second adjustment unit 2 directly drives the air outlet unit 4 to rotate around the vertical axis, causing the airflow to deflect up and down. When oblique airflow is required (such as to the upper left), the first adjustment unit 1 and the second adjustment unit 2 work together: the rotating ring 3 drives the air outlet unit 4 to move horizontally to the left, while the second adjustment unit 2 drives the air outlet unit 4 to rotate upward. The two actions are combined to achieve precise multi-dimensional adjustment. The horizontal movement of the rotating ring 3 and the vertical movement of the air outlet unit 4 are independent and synchronous, avoiding the cumbersome nature of traditional step-by-step operations.

[0041] The coordinated control of the first adjustment unit 1 and the second adjustment unit 2 replaces manual step-by-step operation, allowing users to achieve synchronous horizontal and vertical adjustment with a single button press on the controller. The integrated design of the rotating ring 3 and the air outlet unit 4 reduces the space occupied by traditional multiple sets of motors and transmission components, resulting in a more compact structure. The first adjustment unit 1 directly drives the rotating ring 3 to rotate horizontally, and the second adjustment unit 2 directly drives the air outlet unit 4 to rotate vertically. The transmission path is short and there are no multi-stage gear engagements, reducing mechanical wear and error risks.

[0042] In a specific embodiment, the air outlet unit 4 includes an air outlet housing 41, a flow guiding module 42, a first blade 43, a second blade 44, and an opening adjustment module 45. The flow guiding module 42 is disposed inside the air outlet housing 41. The first blade 43 and the second blade 44 are disposed at the opening of the air outlet housing 41. The opening adjustment module 45 is connected to one end of the first blade 43 and one end of the second blade 44, and is used to adjust the angle between the other end of the first blade 43 and the other end of the second blade 44.

[0043] The air outlet housing 41 serves as the main frame of the airflow channel, and a flow guiding module 42 is fixedly installed inside it to guide the airflow direction. A first blade 43 and a second blade 44 are provided at the opening of the air outlet housing 41, and one end of the two blades is linked by an opening adjustment module 45. The opening adjustment module 45 controls the opening angle of the air outlet by adjusting the relative distance between the ends of the two blades to change the included angle between the blades.

[0044] The air outlet housing 41 provides a stable channel for airflow and supports other components; the airflow guiding module 42 optimizes airflow distribution and reduces turbulence through internal guide vanes or curved surface design; the first blade 43 and the second blade 44 control the opening of the air outlet by changing the included angle, thereby adjusting the air volume; the opening adjustment module 45 drives the linkage of the ends of the two blades to realize the synchronous adjustment of the blade opening angle, ensuring uniform air volume change.

[0045] When airflow adjustment is required, the opening adjustment module 45 receives a control signal and activates the drive component (such as a motor or gear set) to pull the first blade 43 and the second blade 44, causing the other ends of the two blades to rotate synchronously. The included angle between the blades increases or decreases accordingly, thereby expanding or shrinking the air outlet opening and changing the airflow. The airflow guiding module 42 rectifies the airflow inside the air outlet housing 41, ensuring that the airflow passes evenly through the blade gaps and avoiding local eddies.

[0046] In a specific embodiment, the opening adjustment module 45 includes a third motor 451, a third shaft 452, a first bevel gear 453, a second bevel gear 454, and a third bevel gear 455. The output end of the third motor 451 is connected to one end of the third shaft 452, and the other end of the third shaft 452 is connected to the first bevel gear 453. The first bevel gear 453 meshes with the second bevel gear 454, and the second bevel gear 454 meshes with the third bevel gear 455. The first blade 43 is connected to the first bevel gear 453, and the second blade 44 is connected to the third bevel gear 455.

[0047] The output end of the third motor 451 is fixedly connected to one end of the third shaft 452, and the other end of the third shaft 452 is vertically mounted with the first bevel gear 453; the first bevel gear 453 meshes with the second bevel gear 454, and the axis of the second bevel gear 454 is perpendicular to the axis of the first bevel gear 453; the second bevel gear 454 further meshes with the third bevel gear 455, and the axis of the third bevel gear 455 is parallel to the axis of the second bevel gear 454; the first blade 43 is fixedly connected to the center of the first bevel gear 453 through its rotating shaft, and the second blade 44 is fixedly connected to the center of the third bevel gear 455 through its rotating shaft, so that the rotation axes of the two blades are parallel to each other and located on both sides of the opening of the air outlet housing 41.

[0048] The third motor 451 serves as a power source, transmitting rotational motion to the first bevel gear 453 via the third shaft 452. The first bevel gear 453 converts the horizontal rotation into the vertical rotation of the second bevel gear 454, which in turn drives the third bevel gear 455 to rotate in the same direction. The first bevel gear 453 and the third bevel gear 455 drive the first blade 43 and the second blade 44 to rotate synchronously in opposite directions via rotating shafts, thereby achieving adjustment of the opening and closing angles at the ends of the two blades.

[0049] When airflow adjustment is required, the third motor 451 drives the third shaft 452 to rotate, causing the first bevel gear 453 to rotate clockwise or counterclockwise. The rotation of the first bevel gear 453 drives the second bevel gear 454 to rotate in the opposite direction through meshing. The second bevel gear 454 further drives the third bevel gear 455 to rotate in the same direction as the second bevel gear 454. Since the first blade 43 is fixed on the shaft of the first bevel gear 453 and the second blade 44 is fixed on the shaft of the third bevel gear 455, and the two gears rotate in opposite directions (for example, when the first bevel gear 453 rotates clockwise, the third bevel gear 455 rotates counterclockwise), the ends of the first blade 43 and the second blade 44 synchronously close inward or expand outward, thereby reducing or expanding the angle between the blades and precisely controlling the opening of the air outlet and the airflow. During this process, the airflow guiding module 42 ensures that the airflow passes evenly through the blade gaps, avoiding turbulence interference.

[0050] In a specific embodiment, the first adjustment unit 1 includes a first motor 11 and a first shaft 12. The output end of the first motor 11 is connected to one end of the first shaft 12, and the other end of the first shaft 12 is fixed to the rotating ring 3.

[0051] The output end of the first motor 11 is rigidly connected to one end of the first shaft 12 via a coupling or direct plug-in connection. The other end of the first shaft 12 passes through the central hole of the rotating ring 3 and is fixed to the rotating ring 3 via a keyway, screw, or welding, so that the rotation axis of the rotating ring 3 coincides with the axis of the first shaft 12. When the first motor 11 drives the first shaft 12 to rotate around its own axis, the rotating ring 3 rotates synchronously, and the rotating ring 3 is fitted around the outer circumference of the air outlet housing to ensure stability during lateral rotation. The first motor 11, as a power source, drives the first shaft 12 to rotate around its axis by outputting rotational torque; the first shaft 12, as a transmission component, directly transmits the rotational motion of the first motor 11 to the rotating ring 3, thereby converting the power into the lateral rotation of the rotating ring 3, realizing the overall left-right adjustment of the air outlet.

[0052] When the lateral angle of the air outlet needs to be adjusted, the first motor 11 receives a control signal and starts, driving the first shaft 12 to rotate clockwise or counterclockwise around its axis. The rotation of the first shaft 12 directly drives the rotating ring 3 to rotate synchronously through a fixed connection. The rotating ring 3, through its hinged structure with the air outlet unit 4, pulls the air outlet unit 4 to swing left and right, thereby changing the lateral deflection angle of the airflow direction. For example, when the first motor 11 rotates clockwise, the rotating ring 3 drives the air outlet unit 4 to deflect to the right, and vice versa.

[0053] In addition, the first motor 11 is a servo motor. The servo motor has high-precision angle control, fast response and closed-loop feedback functions. It can accurately adjust the rotation angle and speed of the first axis 12 according to the controller instructions, avoiding the step loss or overshoot problems of traditional stepper motors. Its built-in encoder can provide real-time feedback on the rotation position, ensuring the lateral adjustment accuracy and repeatability of the rotating ring 3. It also supports dynamic adjustment to adapt to different working conditions, such as correcting the air outlet angle in real time according to sensor data, thereby improving the overall stability of the system and the user experience.

[0054] In a specific embodiment, the second adjustment unit 2 includes a second motor 21 and a second shaft 22. The output end of the second motor 21 is connected to one end of the second shaft 22, and the other end of the second shaft 22 is hinged to the air outlet unit 4 through a hole 46 on the air outlet housing 41.

[0055] The output end of the second motor 21 is rigidly connected to one end of the second shaft 22 via a coupling; the other end of the second shaft 22 passes through the hole 46 on the air outlet housing 41 and is hinged to the air outlet unit 4 via a bearing or hinge structure, so that the rotation axis of the second shaft 22 coincides with the longitudinal rotation axis of the air outlet unit 4. The air outlet unit 4 can rotate freely around the axis of the second shaft 22 through this hinge point, and the design of the hole 46 provides axial support for the second shaft 22, ensuring stability during longitudinal adjustment. The second motor 21, as a power source, drives the second shaft 22 to rotate around its axis by outputting rotational torque; the second shaft 22, as a transmission component, converts the rotational motion of the second motor 21 into the oscillation of the air outlet unit 4 around its longitudinal axis, thereby directly controlling the up-and-down deflection of the airflow direction.

[0056] When the longitudinal angle of the air outlet needs to be adjusted, the second motor 21 receives a control signal and starts, driving the second shaft 22 to rotate clockwise or counterclockwise. The rotation of the second shaft 22 causes the air outlet unit 4 to swing up and down around the longitudinal axis through the hinge point. For example, when the second motor 21 rotates clockwise, the air outlet unit 4 deflects upward, and vice versa. Since the air outlet unit 4 is connected to the rotating ring 3 through the hinge structure, its longitudinal adjustment action can be independent of the lateral rotation of the rotating ring 3, or it can be coordinated with the lateral adjustment to achieve oblique air delivery.

[0057] In addition, the second motor 21 is a servo motor.

[0058] In a specific embodiment, the air outlet structure further includes a housing 5, which is an annular structure with a notch, and the housing 5 is arranged around the rotating ring 3; the output end of the first adjustment unit 1 passes through the housing 5 and is fixed to the rotating ring 3, and the output end of the second adjustment unit 2 passes through the notch, so that the air outlet unit 4 and the rotating ring 3 are connected and fixed.

[0059] The outer casing 5 has a ring structure and is arranged around the rotating ring 3. A notch is provided on one side of the outer casing 5. The first motor 11 of the first adjustment unit 1 is fixed to the outer wall of the outer casing 5. Its output end (first shaft 12) passes through the reserved hole of the outer casing 5 and is fixedly connected to the center of the rotating ring 3, driving the rotating ring 3 to rotate around the horizontal axis. The second motor 21 of the second adjustment unit 2 is installed near the notch of the outer casing 5. Its output end (second shaft 22) passes through the notch and is connected to the air outlet unit 4 through a hinge structure. The notch provides space for the movement of the second adjustment unit 2 and avoids the outer casing 5 from interfering with the longitudinal rotation of the air outlet unit 4. The rotating ring 3 is nested inside the outer casing 5. When it rotates horizontally, it drives the air outlet unit 4 to swing left and right as a whole. At the same time, the air outlet unit 4 is driven by the second adjustment unit 2 to independently deflect up and down around the longitudinal axis, realizing multi-dimensional adjustment.

[0060] The outer shell 5 serves as a protective and support structure. On the one hand, it encloses the rotating ring 3 to prevent dust from entering and reduce mechanical wear. On the other hand, the ring design fixes the position of the first adjustment unit 1, ensuring the lateral rotation stability of the rotating ring 3. The notch in the outer shell 5 provides space for the connection between the second adjustment unit 2 and the air outlet unit 4, avoiding mechanical interference during longitudinal adjustment.

[0061] In a specific embodiment, guide rails 51 are provided on both sides of the notch, and sliders 23 are provided on the second motor 21. The two sides of the sliders 23 cooperate with the guide rails 51 so that the second motor 21 can rotate along the first direction with the air outlet unit 4.

[0062] The guide rail 51 consists of two arc-shaped structures, fixed to both sides of the notch in the outer casing 5. The slider 23 is a U-shaped slot structure, installed on both sides of the second motor 21. Rollers or sliding bushings are provided inside the slot, which fit tightly with the arc-shaped surface of the guide rail 51. When the rotating ring 3 drives the air outlet unit 4 to rotate laterally, the second motor 21 slides along the arc-shaped trajectory of the guide rail 51 through the slider 23, ensuring that the second motor 21 always maintains a hinged relationship with the air outlet unit 4.

[0063] Specifically, the guide rail 51 provides a fixed guide path for the lateral movement of the second motor 21, restricting its movement direction to be consistent with the lateral rotation trajectory of the rotating ring 3, preventing deviation or jamming. The slider 23 dynamically connects the second motor 21 to the guide rail 51, reducing movement resistance through sliding or rolling friction, ensuring that the second motor 21 moves smoothly when rotating laterally with the air outlet unit 4. When the two work together, the arc-shaped trajectory of the guide rail 51 constrains the movement direction of the slider 23, ensuring that the second motor 21 is always aligned with the hinge point of the air outlet unit 4 during lateral rotation. At the same time, during longitudinal adjustment, the slider 23 finely adjusts its position along the guide rail 51 to avoid mechanical interference and ensure the independence and coordination of lateral and longitudinal adjustments.

[0064] In a specific embodiment, the air outlet structure further includes a sensor unit 6 and a controller 7. The controller 7 is connected to the sensor unit 6 and is also connected to the first adjustment unit 1, the second adjustment unit 2, and the air outlet unit 4. The sensor unit 6 is used to collect the direction and distance of the target position and transmit them to the controller 7. The controller 7 controls the working state of the first adjustment unit 1, the second adjustment unit 2, and the air outlet unit 4 according to the direction and distance.

[0065] Sensor unit 6 is responsible for collecting real-time information on the direction and distance of target positions (such as a passenger's head or body) inside the vehicle, for example, by detecting the passenger's position using infrared or a camera. After receiving the data from sensor unit 6, controller 7 analyzes the spatial coordinates of the target position relative to the air vent and calculates the adjustment parameters (such as motor rotation angle and blade opening / closing angle) required by the first adjustment unit 1, the second adjustment unit 2, and the air vent unit 4. Then, it sends control commands to each unit. When the two work together, sensor unit 6 continuously monitors changes in passenger position, and controller 7 dynamically adjusts the air vent angle and airflow. For example, when a passenger moves, the system automatically tracks and recalibrates the airflow direction to achieve intelligent adjustment.

[0066] Additionally, sensor unit 6 may include an infrared thermal imaging sensor (to locate passengers by body temperature), a camera (to determine passenger posture and distance using image recognition algorithms), an ultrasonic sensor (to calculate distance by sound wave reflection), a pressure sensor (to determine passenger position by detecting seat pressure distribution), or millimeter-wave radar (to accurately detect human position and movement trajectory). For example, a combination of a camera and an infrared sensor can simultaneously acquire visual information and heat source distribution, and controller 7 improves positioning accuracy and adapts to complex environments by fusing data from multiple sensors.

[0067] After the sensor unit 6 detects the passenger's position, the controller 7 analyzes the target direction and distance, and calculates the adjustment parameters of the first adjustment unit 1, the second adjustment unit 2, and the opening adjustment module 45. For air outlet direction adjustment: the first motor 11 drives the first shaft 12 to rotate, causing the rotating ring 3 to rotate left and right around the horizontal axis. The air outlet unit 4 swings laterally with the rotating ring 3 through the hinge structure. At the same time, the second motor 21 drives the second shaft 22 to rotate, and through the hinge point between the hole 46 and the air outlet unit 4, drives the air outlet unit 4 to swing up and down around the longitudinal axis. The slider 23 slides along the guide rail 51 to ensure that the second motor 21 moves smoothly with the lateral rotation, ultimately realizing multi-dimensional adjustment of the airflow direction. For air volume adjustment: the third motor 451 drives the third shaft 452 to rotate, causing the first bevel gear 453 to rotate. Through the meshing second bevel gear 454 and third bevel gear 455, the first blade 43 and the second blade 44 rotate synchronously in opposite directions, and the included angle between the ends of the two blades decreases or increases. The airflow guiding module 42 optimizes the airflow distribution within the air outlet housing 41 and reduces turbulence. The entire process is coordinated by the controller 7, and the sensor unit 6 provides real-time feedback on the passenger's position, forming a closed-loop control and realizing intelligent adjustment.

[0068] Example 2

[0069] This embodiment provides an air conditioner, which includes the air outlet structure described in Embodiment 1.

[0070] The air conditioner provided in this embodiment uses the air outlet structure in Embodiment 1, which can automatically adjust the air outlet direction and air volume according to the real-time position of the passenger. For example, the sensor unit tracks the position of the passenger's head in real time and links the first adjustment unit and the second adjustment unit to accurately adjust the horizontal and vertical air supply angles, avoiding the problems of direct blowing or uneven cooling and heating in traditional air conditioners. At the same time, the opening adjustment module drives the blades to open and close synchronously through the bevel gear set, realizing stepless adjustment of air volume. It can quickly respond to changes in demand (such as passenger movement or ambient temperature fluctuations) and reduce energy waste. The design of the outer shell and guide rail slider ensures stability and low noise operation during the adjustment process, ultimately improving user comfort while taking into account energy efficiency and reliability.

[0072] This embodiment provides a car, which includes the air conditioner described in Embodiment 2.

[0073] In summary, it is readily understood by those skilled in the art that, without conflict, the aforementioned advantageous technical features can be freely combined and superimposed.

[0074] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
