Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning vent technology, and in particular to a single-actuator air vent. Background Technology

[0002] Traditional automotive air conditioning vents typically employ manual adjustment or a single motor drive, resulting in limited functionality, numerous components, complex structure, and high cost. For example, existing vents often require multiple motors to drive guide vanes in different directions, leading to system complexity and reduced reliability. Furthermore, traditional vents lack precise control over airflow direction, resulting in a poor user experience. Utility Model Content

[0003] To address the shortcomings and defects of existing technologies, a single-actuator air outlet is provided, which achieves multiple functions through one actuator and two clutches, reducing the number of parts, simplifying the structure, lowering costs, and improving system reliability and user experience.

[0004] A single-actuator air outlet, comprising:

[0005] The housing is provided with an air outlet channel, and the air outlet channel is provided with a main air guide vane and a secondary air guide vane;

[0006] The housing is also equipped with a motor, a first clutch, a second clutch, and a transmission assembly.

[0007] The transmission assembly includes a movable part and a rotating body. The movable part is movably lateral and is linked to the secondary guide vanes. When the movable part moves left and right, it drives the secondary guide vanes to swing left and right. The rotating body is threadedly connected to the movable part.

[0008] The motor is connected to the first clutch and the second clutch via gear meshing. The first clutch is connected to the main wind vane, and the second clutch is connected to the rotating body.

[0009] With the above structure, the air outlet of the single actuator of this utility model has the following advantages compared with the prior art: the output end of the motor is provided with a driving gear, which meshes with the driven gears on the first clutch and the second clutch respectively.

[0010] One driven gear is connected to the main guide vane via a first clutch, and the other driven gear is connected to the secondary guide vane via a second clutch. Both the first and second clutches are electromagnetic couplers.

[0011] When the first clutch is engaged and the second clutch is disengaged, the rotation of the motor-driven drive gear can drive the main guide vanes to perform corresponding actions through the driven gear (the main guide vanes can be configured to swing up and down, etc.), but it cannot drive the secondary guide vanes to perform corresponding actions through the driven gear.

[0012] When the first clutch is disengaged and the second clutch is engaged, the driving gear cannot drive the main guide vanes to perform corresponding actions via the driven gear when the driving gear rotates. However, the secondary guide vanes can be driven to perform corresponding actions via the driven gear and transmission components.

[0013] The transmission component adopts a threaded transmission method. When the second clutch is in a coupled state, the rotating body converts the rotational motion of the second clutch into the left and right translational motion of the movable part through the threaded connection, thereby driving the secondary guide vanes to swing left and right.

[0014] After the above improvements, multiple functions can be achieved through one motor and two clutches. It can flexibly control the independent corresponding actions of two blades with different functions, and has the characteristics of fewer parts, simple structure and low cost.

[0015] The transmission component adopts threaded drive, which not only has a compact structure, but also improves transmission accuracy and reliability, solving the problem of complex and faulty transmission components in the existing technology.

[0016] As an improvement of this utility model, a transmission pin is provided on the movable part.

[0017] The number of secondary guide vanes is several, and each of the vanes has a crank pin on its shaft. Multiple crank pins are hinged to the same linkage rod to achieve mutual linkage. The linkage rod is provided with a transmission groove that extends forward and backward, and the transmission pin enters into the transmission groove.

[0018] As an improvement of this utility model, the movable part has a guide hole that is opened laterally, and the housing is provided with an insertion guide hole and a guide member that limits the left and right translation of the movable part.

[0019] As an improvement of this utility model, the movable part is provided with a spiral body extending spirally to one end.

[0020] The rotating body is provided with a screw hole for the screw to engage.

[0021] As an improvement of this utility model, the main air blade is set at the air inlet end of the air outlet channel, and the main air blade can swing up and down to control the air intake of the air outlet channel.

[0022] As an improvement of this utility model, there are two air outlet channels, the two air outlet channels output intersecting airflows, the air inlet ends of the two air outlet channels are connected, and they share a common air supply channel. The main air blades swing up and down to control the air intake of the two air outlet channels.

[0023] As an improvement of this utility model, the two air outlet channels are respectively equipped with interconnected secondary air guide vanes.

[0024] The movable part is located between the two air outlet channels, and the movable part is linked to the secondary air guide vanes in the two air outlet channels respectively. Attached Figure Description

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Please see Figures 1-5 As shown,

[0033] A single-actuator air outlet, comprising:

[0034] The housing 1 is provided with an air outlet duct 1.1, and the air outlet duct 1.1 is provided with a main air guide vane 2 and a secondary air guide vane 3;

[0035] The housing 1 is also equipped with a motor 4, a first clutch 5, a second clutch 6, and a transmission assembly.

[0036] The transmission assembly includes a movable part 8 and a rotating body 9. The movable part 8 is configured to move left and right and is linked with the secondary guide vane 3. When the movable part 8 moves left and right, it can drive the secondary guide vane 3 to swing left and right. The rotating body 9 is threadedly connected to the movable part 8.

[0037] The motor 4 is connected to the first clutch 5 and the second clutch 6 through gear meshing. The first clutch 5 is connected to the main fan blade 2, and the second clutch 6 is connected to the rotating body 9.

[0038] The output end of the motor 4 is provided with a drive gear 11, which meshes with the driven gears 12 on the first clutch 5 and the second clutch 6 respectively.

[0039] One driven gear 12 is connected to the main guide vane 2 via the first clutch 5, and the other driven gear 12 is connected to the secondary guide vane 3 via the second clutch 6. Both the first clutch 5 and the second clutch 6 are electromagnetic couplers. Specifically, the driven gear 12 is connected to the input end of the clutch, and the output end of the clutch is provided with a coaxial spline shaft 13. One spline shaft 13 is coaxially arranged with the main guide vane 2, and the other spline shaft 13 is coaxially arranged with the rotating body 9. The input end and the output end of the clutch are coupled or disengaged.

[0040] When the first clutch 5 is in the coupled state and the second clutch 6 is in the disengaged state, the motor 4 drives the rotation of the drive gear 11, which can drive the main guide vane 2 to perform corresponding actions through the driven gear 12 (the main guide vane 2 can be configured to swing up and down, etc.), but cannot drive the secondary guide vane 3 to perform corresponding actions through the driven gear 12.

[0041] When the first clutch 5 is disengaged and the second clutch 6 is engaged, the driven gear 11 cannot drive the main guide vane 2 to perform corresponding actions when it rotates. However, the secondary guide vane 3 can be driven to perform corresponding actions through the driven gear 12 and the transmission assembly.

[0042] The transmission component adopts a threaded transmission method. When the second clutch 6 is in a coupled state, the rotating body 9 converts the rotational motion of the second clutch 6 into the left and right translational motion of the movable part 8 through the threaded connection, thereby driving the secondary guide vane 3 to swing left and right.

[0043] After the above improvements, multiple functions can be achieved through one motor 4 and two clutches. It can flexibly control the independent corresponding actions of two blades with different functions, and has the characteristics of fewer parts, simple structure and low cost.

[0044] The transmission component adopts threaded drive, which not only has a compact structure, but also improves transmission accuracy and reliability, solving the problem of complex and faulty transmission components in the existing technology.

[0045] Please see Figure 1 , Figure 4 , Figure 5 As shown, a transmission pin 8.1 is provided on the movable part 8.

[0046] The number of secondary guide vanes 3 is several, and each of the vanes has a crank pin 3.1 on its shaft. The multiple crank pins 3.1 are hinged to the same linkage rod 3.11 to achieve mutual linkage. The linkage rod 3.11 is provided with a transmission groove 3.111 extending forward and backward, and the transmission pin 8.1 enters into the transmission groove 3.111.

[0047] After the above improvements, multiple secondary guide vanes 3 are set in the air outlet duct 1.1, and the multiple secondary guide vanes 3 are set synchronously and in linkage. When they swing left and right, they have a consistent swing angle, which has the characteristics of good airflow guidance effect and improves the adjustment accuracy of the air outlet direction.

[0048] The movable part 8 has a horizontally opened guide hole 8.2, and the housing 1 is provided with an insertion guide hole 8.2 and a guide member 10 that limits the left and right translation of the movable part 8.

[0049] Among them, the guide hole 8.2 can be a rectangular hole, and the guide member 10 is a structure adapted to the rectangular hole, which can limit the left and right translation of the movable part 8, so that it can move reliably and ensure the accuracy of blade oscillation control.

[0050] The active section 8 is equipped with a spiral body 8.3 extending spirally to one end.

[0051] The rotating body 9 is provided with a screw hole 9.1 for the screw body 8.3 to fit.

[0052] The above improvements result in a simple, compact structure and reliable operation.

[0053] As one arrangement of this application: the main air blade 2 is set at the air inlet end of the air outlet channel 1.1, and the main air blade 2 can swing up and down to control the air intake of the air outlet channel 1.1.

[0054] As another arrangement of this application: there are two air outlet channels 1.1, the two air outlet channels 1.1 output intersecting airflows, the air inlet ends of the two air outlet channels 1.1 are connected, and they share a common air supply channel. The main air fan blades 2 swing up and down to control the air intake of the two air outlet channels 1.1.

[0055] The two air outlet ducts 1.1 are each equipped with interconnected secondary air guide vanes 3.

[0056] The movable part 8 is set between the two air outlet channels 1.1, and the movable part 8 is linked with the secondary air guide vanes 3 in the two air outlet channels 1.1 respectively.

[0057] The movable part 8 is linked with the secondary air guide blades 3 in the two air outlet channels 1.1, which enables the secondary air guide blades 3 in the two air outlet channels 1.1 to be set up synchronously. When swinging left and right, they have a consistent swing angle, which has the characteristics of good airflow guidance effect and improves the adjustment accuracy of air outlet direction.

[0058] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
