For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances. Where possible, the same or similar figure numbers used in this application refer to the same parts.

[0039] Figures 1A-1E The specific structure of the actuator device 100 of the present application is shown, wherein Figure 1A is a three-dimensional diagram of the actuator device 100 of the present application, Figure 1B The actuator cover 102 of the actuator device 100 is hidden so as to show more components inside the actuator device 100. Figure 1C Will Figure 1B The driving gear 124 of the actuator device 100 is separated to illustrate the matching relationship between the driving gear 124 and the first rotation transmission device 132 and the second rotation transmission device 134. Figure 1D is a three-dimensional diagram of the driving gear 124 in the actuator device 100 of the present application, Figure 1EIt is a three-dimensional view of the rotary transmission device in the actuator device 100 of the present application.

[0040] like Figure 1A As shown, the actuator device 100 includes an actuator cover 102 and an actuator housing 104, and the actuator cover 102 and the actuator housing 104 are fixed together by connecting members 106, 107 (such as screws). The actuator device 100 has two output shafts 152, 154, and the two output shafts 152, 154 are arranged parallel to each other and at a certain distance. The actuator cover 102 has two shaft holes 192, 194, whose size and position arrangement can just expose the ends of the two output shafts 152, 154, so as to facilitate the connection of the two output shafts 152, 154 with the driven member.

[0041] For those skilled in the art, in some other embodiments, the two output shafts 152 and 154 may also be arranged in a non-parallel manner. For example, the rotation axes of the two output shafts 152 and 154 are arranged at a certain angle to each other.

[0042] like Figure 1B and 1C As shown, the actuator device 100 is internally provided with a driving component 112 , such as a rotary driving motor, a transmission gear 114 , a drive gear 124 , a first rotary transmission device 132 , and a second rotary transmission device 134 .

[0043] The rotary drive motor 112 includes a drive rotation shaft 120, which can rotate in a first rotation direction or a second rotation direction, wherein the first rotation direction is opposite to the second rotation direction. The drive rotation shaft 120 is meshed with the transmission gear 114 by a worm gear. The rotary drive motor 112 can be controlled by a control mechanism (not shown in the figure), so that the drive rotation shaft 120 rotates in the first rotation direction or the second rotation direction according to the control requirements.

[0044] The transmission gear 114 has a rotation axis 115 and a transmission gear first tooth portion 118 and a transmission gear second tooth portion 116 which are coaxial and spaced apart in the axial direction. The worm structure driving the rotation axis 120 can mesh with the transmission gear first tooth portion 118 of the transmission gear 114 in a worm gear manner and transmit the torque output by the rotary drive motor 112 to the transmission gear 114, so that the transmission gear 114 rotates around the rotation axis 115. The rotation of the transmission gear 114 can further drive the driving gear 124 to rotate through the tooth meshing of the transmission gear second tooth portion 116 with the driving gear 124.

[0045] Since the outer diameter and the number of teeth of the first gear tooth portion 118 of the transmission gear 114 are greater than the outer diameter and the number of teeth of the second gear tooth portion 116, the transmission gear 114 can play a deceleration role in the process of transmitting the rotational torque (for example, reducing the rotational speed of the rotary drive motor 112), and can be used as a deceleration mechanism of the actuator device 100.

[0046] like Figure 1C and 1D As shown, the driving gear 124 includes a driving gear rotating shaft 142 and a driving gear first tooth portion 146 and a driving gear second tooth portion 144 that are coaxial and axially spaced. The driving gear first tooth portion 146 can be meshed with the transmission gear second tooth portion 116, so that the driving gear 124 can be driven by the drive rotating shaft 120 to rotate in a clockwise or counterclockwise direction. The driving gear second tooth portion 144 can be meshed with the first rotation transmission device 132 and the second rotation transmission device 134 respectively, so as to transmit the rotation of the driving gear 124 to the first rotation transmission device 132 and the second rotation transmission device 134 at the same time.

[0047] In the embodiment of the present application, the transmission gear 114 and the driving gear 124 can also serve as a reduction mechanism of the actuator device 100. The transmission of the transmission gear 114 and the driving gear 124 can transmit the rotation speed of the driving rotating shaft 120 of the rotary driving motor 112 to the two output shafts 152 and 154 at a reduction ratio of 480:1.

[0048] Since the first rotation transmission device 132 and the second rotation transmission device 134 have similar structures and the same working principles, this article only describes the specific structure of the first rotation transmission device 132, and the structure of the second rotation transmission device 134 is not repeated.

[0049] like Figure 1E As shown, the first rotary transmission device 132 includes a first clutch device, such as a roller clutch or a wedge clutch, wherein the first clutch device includes at least one roller or one wedge. The first clutch device has an inner ring 178, an outer ring 172, two cylindrical rollers 174, 175 and two elastic elements 176, 177, wherein the inner ring 178 has two wedge surfaces 182, 183, and the outer ring 172 has an outer tooth portion 171 and an inner cylindrical ring surface 173. The outer ring 172 has a rotation axis 162, and the outer tooth portion 171 can mesh with the second tooth portion 144 of the driving gear 124, so that the outer ring 172 can rotate around the rotation axis 162 under the drive of the driving gear 124. It should be known to those skilled in the art that in some other embodiments, the number of cylindrical rollers and wedge surfaces is not limited to two, and can also be set to one or more than two as required.

[0050] The transmission process of the first clutch device is as follows: when the outer ring 172 rotates clockwise, the cylindrical rollers 174, 175 in contact with the outer ring 172 are subjected to friction and move in the same direction as the outer ring 172, at which time the elastic elements 176, 177 are compressed, causing the elastic elements 176, 177 to deform, and at the same time the cylindrical rollers 174, 175 move toward the area where the space of the wedge-shaped area increases, so that the contact force between the inner cylindrical surface 173 of the outer ring, the wedge-shaped surfaces 182, 183 of the inner ring and the cylindrical rollers 174, 175 becomes smaller, which is insufficient to drive the inner ring 178 to rotate. Therefore, when the outer ring 172 rotates clockwise, the inner ring 178 is stationary. When the outer ring 172 rotates counterclockwise, the cylindrical rollers 174, 175 in contact with the outer ring 172 are subjected to friction and move in the same direction as the outer ring 172. The cylindrical rollers 174, 175 move toward the area where the space of the wedge-shaped area is reduced. At the same time, the elastic elements 176, 177 also push the rollers to move in the direction where the wedge-shaped area is smaller, so that the contact force between the inner cylindrical surface 173 of the outer ring, the inner wedge-shaped surfaces 182, 183 and the cylindrical rollers 174, 175 increases, and the inner ring 178 rotates synchronously in the same direction as the outer ring 172. Therefore, when the outer ring 172 rotates counterclockwise, the inner ring 178 moves synchronously in the same direction as the outer ring 172, that is, the inner ring 178 also rotates counterclockwise.

[0051] The first rotary transmission device 132 also has a first output shaft 152, which is coaxially fixed to the inner ring 178. When the inner ring 178 rotates counterclockwise, it can transmit the rotational torque to the first output shaft 152 to drive the driven component. It is worth noting that the rotation axis 162 of the outer ring 172 is coaxially arranged with the rotation axis of the first output shaft 152, so the outer ring 172, the inner ring 178 and the first output shaft 152 have a common first rotation axis 162.

[0052] Similarly, the second rotary transmission device 134 includes a second clutch device, such as a roller clutch or a wedge clutch, wherein the second clutch device includes at least one roller or at least one wedge. The second rotary transmission device 134 also has a second output shaft 154 and a second rotation axis 164. The inner ring structure of the second rotary transmission device 134 is centrally symmetrical with the inner ring structure of the first rotary transmission device 132. Therefore, contrary to the arrangement of the first rotary transmission device 132, the second rotary transmission device 134 can only transmit the clockwise rotation of its outer ring to the second output shaft 154, but cannot transmit the counterclockwise rotation of its outer ring to the second output shaft 154.

[0053] like Figure 1B-1CAs shown, the first clutch device of the first rotating transmission device 132 and the second clutch device of the second rotating transmission device 134 are arranged at the final output stage of the actuator device 100, so that the first clutch device and the second clutch device can share a set of transmission mechanisms (for example, including a transmission gear 114 and a driving gear 124), thereby making the structure of the actuator device 100 more streamlined to save the manufacturing cost of the actuator device 100.

[0054] Among them, the first output shaft 152 and the second output shaft 154 are parallel to each other and separated by a certain distance from the driving gear rotating shaft 142, that is, the first output shaft 152 and the second output shaft 154 can be arranged symmetrically on both sides or approximately on both sides of the driving gear rotating shaft 142, so that the torque output of the first output shaft 152 and the second output shaft 154 is more balanced, the output is more stable, and no vibration or abnormal noise will be generated.

[0055] For ordinary technicians in this field, in different embodiments, the first output shaft 152 and the second output shaft 154 can be arranged on both sides of the driving gear rotating shaft 142 and the rotation centers of the three can be arranged in a colinear manner, or the lines connecting the rotation centers of the three can be arranged roughly in a triangle.

[0056] For those skilled in the art, in some other embodiments, the two output shafts 152, 154 may also be arranged to be non-parallel. For example, the outer ring teeth of the first rotary transmission device 132 or the second rotary transmission device 134 are meshed with the second tooth portion 144 of the driving gear 124 in the form of a bevel gear, so that the output shaft 152 or 154 of the first rotary transmission device 132 or the second rotary transmission device 134 is at a certain angle to the driving gear rotation shaft 142, so that the rotation axes of the two output shafts 152, 154 are also arranged at a certain angle to each other.

[0057] Therefore, the above first clutch device and the second clutch device are configured such that when the driving gear 124 rotates in the clockwise direction, the outer rings of the first clutch device and the second clutch device rotate counterclockwise, so that the outer ring of the first clutch device and the inner ring are in a combined state, and the outer ring of the second clutch device and the inner ring are in a separated state, so that the driving force of the rotary drive motor 112 can be transmitted to the first output shaft 152 but cannot be transmitted to the second output shaft 154, so that the first output shaft 152 can rotate and the second output shaft 154 cannot rotate. On the contrary, when the driving gear 124 rotates in the counterclockwise direction, the outer rings of the first clutch device and the second clutch device rotate clockwise, the outer ring of the first clutch device and the inner ring are in a separated state, and the outer ring of the second clutch device and the inner ring are in a combined state, so that the driving force of the rotary drive motor 112 can be transmitted to the second output shaft 154 but cannot be transmitted to the first output shaft 152, so that the first output shaft 152 cannot rotate and the second output shaft 154 can rotate.

[0058] For ordinary technicians in this field, in some other embodiments, based on the same principle of the clutch device, the first clutch device or the second clutch device can also be set to a mode with inner ring input and outer ring output, or a mode with inner ring input and outer ring output and outer ring input and inner ring output mixed.

[0059] It can be seen that the actuator device of the present application is a dual-output actuator assembly with a built-in clutch, which can at least achieve the following beneficial technical effects:

[0060] First, the actuator device of the present application has a stable clutch process and output, and will not generate vibration or abnormal noise. It can achieve dual outputs using a single actuator. The two output shafts are symmetrically arranged about the rotation axis of the driving gear and are spaced a certain distance apart so that the outputs of each output shaft are relatively balanced and will not interfere with each other.

[0061] Second, the actuator device of the present application adopts a stepless one-way clutch, and two or more stepless one-way clutches can be used according to working conditions.

[0062] Third, the actuator device of the present application can realize driving functions in 2 or more directions; and the driving functions can realize independent adjustment in 2 or more directions respectively.

[0063] Fourthly, the actuator device solution of the present application has a simple structure, small size and light weight.

[0064] Figure 2A-2B The specific structure of the clutch device 200 of the present application is shown, wherein Figure 2A is a three-dimensional diagram of the clutch device 200 of the present application, Figure 2B The clutch upper cover 212 of the clutch device 200 is hidden so as to show more components inside the clutch device 200 .

[0065] Figure 2A-2B The clutch device 200 is shown with Figure 1A-1B The working principle of the actuator device 100 shown is similar, except that the clutch device 200 omits the driving component and the reduction mechanism based on the actuator device 100, and the torque input of the clutch device 200 is provided by connecting the external driving component (such as an actuator or a motor) through the input shaft.

[0066] like Figure 2A-2B As shown, the clutch device 200 includes a driving gear 225 , a first rotation transmission device 224 and a second rotation transmission device 226 .

[0067] The driving gear 225 includes a driving gear rotating shaft 202, that is, the input shaft of the clutch device 200. The gear rotating shaft 202 is provided with a meshing portion 203 along a circumferential direction for engaging with an external driving device 302 (see Figure 3A ) are connected in a mating manner, so that the gear rotating shaft 202 can be driven by the external driving device 302 to rotate in a clockwise or counterclockwise direction.

[0068] The first rotary transmission device 224 includes a first clutch device and a first output shaft 204, and the second rotary transmission device 226 includes a second clutch device and a second output shaft 206. The first clutch device and the second clutch device are roller clutches or wedge clutches. The working principles of the first clutch device and the second clutch device are the same as the working principles of the clutch device in the actuator device 100 above, and will not be repeated here.

[0069] The first clutch device or the second clutch device is configured as follows: when the gear-driven rotating shaft 202 rotates in a clockwise direction, the first clutch device is in an engaged state and the second clutch device is in a disengaged state, so that the driving force of the gear-driven rotating shaft 202 can be transmitted to the first output shaft 204 but cannot be transmitted to the second output shaft 206, so that the first output shaft 204 can rotate and the second output shaft 206 cannot rotate; when the gear-driven rotating shaft 202 rotates in a counterclockwise direction, the first clutch device is in a disengaged state and the second clutch device is in an engaged state, so that the driving force of the gear-driven rotating shaft 202 can be transmitted to the second output shaft 206 but cannot be transmitted to the first output shaft 204, so that the first output shaft 204 cannot rotate and the second output shaft 206 can rotate.

[0070] The first output shaft 204 and the second output shaft 206 may be parallel to the driving gear rotating shaft 202 and spaced a certain distance apart from each other, and may be symmetrically arranged on both sides of the driving gear rotating shaft 202 .

[0071] For those skilled in the art, in some other embodiments, the first output shaft 204 and the second output shaft 206 may be arranged non-parallel to each other. Referring to the above description of the output shafts in the actuator device 100, the rotation axes of the first output shaft 204 and the second output shaft 206 may be arranged at a certain angle to each other.

[0072] Therefore, the clutch device 200 provided in the present application is a dual-output overrunning clutch system. Similar to the actuator device 100, in the embodiment of the present application, the clutch device 200 can be configured to be in a mode of inner ring input and outer ring output or an outer ring input and inner ring output, or a combination of the above two modes.

[0073] The clutch device of the present application can at least achieve the following beneficial technical effects:

[0074] First, the clutch device of the present application can be used in series with any actuator, and can convert the single output of the actuator into dual outputs. Each output is adjusted independently of each other, and the outputs of the two output shafts will not interfere with each other.

[0075] Second, the clutch device of the present application has similar advantages to the actuator device described above, including but not limited to a stable clutching process, a stable output balance, and no vibration or abnormal noise.

[0076] Figures 3A-3G The specific structure of an embodiment of the air outlet device is shown. Figure 3A To have Figure 2A-2B A perspective view showing an embodiment of an air outlet device of a clutch device, Figure 3B for Figure 3A The exploded view of the air outlet device shown, Figure 3C for Figure 3A The three-dimensional view of the air outlet device after the drive device is hidden, Figure 3D for Figure 3A The driving schematic diagram of the air outlet device at the first viewing angle is shown, Figure 3E for Figure 3A The driving schematic diagram of the air outlet device at the second viewing angle is shown, Figure 3F for Figure 3B A three-dimensional view of the air outlet device from another perspective is shown, Figure 3G for Figure 3B A perspective view of the air outlet device shown from a side perspective. Figure 4A-4B The specific structure of the bevel gear 362 in the air outlet device 300 is shown.

[0077] like Figures 3A-3GAs shown, the air outlet device 300 includes an air outlet housing 301, a clutch device 200 having a single input shaft (driving the gear rotating shaft 202), a driving device 302, a first air outlet 305, and a second air outlet 306 (see Figure 3F ), the first blade group 315 (see Figure 3D and 3G ) and the second blade set 316 (see Figure 3E-3F ). The first blade group 315 is used to control the air outlet direction of the first air outlet 305 and has a first swing shaft 382, ​​and the second blade group 316 is used to control the air outlet direction of the second air outlet 306 and has a second swing shaft 384. The air outlet device 300 also includes a first transmission device 303 and a second transmission device 304. The first transmission device 303 is driven by the first output shaft 204 of the clutch device 200, and is used to drive the first swing shaft 382 to swing, thereby driving the first blade group 315 to swing accordingly. The second transmission device 304 is driven by the second output shaft 206 of the clutch device 200, and is used to drive the second swing shaft 384 to swing, thereby driving the second blade group 316 to swing accordingly. The driving device 302 can be connected in series with the input shaft of the clutch device 200, so as to provide a torque for the rotation of the input shaft. Therefore, referring to Figure 2A-2B As described, when the input shaft of the clutch device 200 rotates clockwise, the first output shaft 204 can rotate, and the second output shaft 206 cannot rotate, thereby driving the first blade group 315 to swing; when the input shaft of the clutch device 200 rotates counterclockwise, the second output shaft 206 can rotate, and the first output shaft 204 cannot rotate, thereby driving the second blade group 316 to swing.

[0078] exist Figure 3C-3D In the illustrated embodiment, the first transmission device 303 includes a first crank-rocker mechanism (refer to the crank-connecting rod structure commonly seen in the mechanical field, and the specific working principle is not repeated here) and a bevel gear 362. Figure 3B The first crank-rocker mechanism includes a first crank-rocker mechanism input end 314, a first crank-rocker mechanism output end 354, and a first connecting rod 334 connecting the first crank-rocker mechanism input end 314 and the first crank-rocker mechanism output end 354. A rocker bevel gear portion 355 is provided in the circumferential direction of the first crank-rocker mechanism output end 354, which is used to mesh with a bevel gear 362. The bevel gear 362 is transmission-connected to the first swing shaft 382 of the first blade group 315, for example, in a gear meshing manner or a coaxial arrangement manner. One end of the first swing shaft 382 is coaxially connected to the first blade group 315, and the other end of the first swing shaft 382 passes through the first air outlet side wall 390 of the first air outlet 305, and a first swing shaft gear portion 364 is provided at the end for mutual meshing with the bevel gear 362.

[0079] like Figure 4A-4B As shown, the bevel gear 362 has a bevel gear body 402 and a bevel gear portion 404. A bevel gear tooth portion 412 is provided on the circumferential outer side of the bevel gear body 402 around the lower half of the outer circumference of the bevel gear body 402, which is used to mesh with the outer teeth 365 of the first swing shaft tooth portion 364 of the first swing shaft 382. Bevel teeth 414 are provided on the bevel gear portion 404, which are used to mesh with the rocker bevel gear portion 355 of the first crank rocker mechanism output end 354. The direction in which the bevel teeth 414 mesh with the bevel gear portion 355 is at a certain angle to the surface where the bevel gear body 402 is located. Therefore, through the meshing transmission of the bevel gear portion 404 of the bevel gear 362 and the rocker bevel gear portion 355 of the first crank rocker mechanism output end 354, the swing torque on the first crank rocker mechanism output end 354 can be changed by a certain angle and transmitted to the bevel gear 362.

When the first crank-rocker mechanism input end 314 rotates, the first crank-rocker mechanism output end 354 can swing in the direction perpendicular to the first air outlet upper wall 391 of the first air outlet 305 driven by the first connecting rod 334; the swing of the first crank-rocker mechanism output end 354 can be converted into the swing of the first swing axis 382 of the first blade group 315 in the direction perpendicular to the first air outlet side wall 390 through the meshing transmission with the bevel gear 362, so that the first blade group 315 swings up and down.

The second crank-rocker mechanism input end 317 can be rotated by the rotation drive of the second output shaft 206. One end of the second swing shaft 384 is connected to the second blade group 316, and the other end of the second swing shaft 384 passes through the second air outlet upper wall 393 of the second air outlet 306, and is matched and connected with the second crank-rocker mechanism output end 356 (for example, coaxially connected).

[0082] During the driving process of the second blade assembly 316, the second crank-rocker mechanism input end 317 can rotate through the rotation drive of the second output shaft 206. When the second crank-rocker mechanism input end 317 rotates, the second crank-rocker mechanism output end 356 can swing in a direction perpendicular to the second air outlet upper wall 393 driven by the second connecting rod 336, and the swing of the second crank-rocker mechanism output end 356 can drive the second swing shaft 384 of the second blade assembly 316 to swing in a direction perpendicular to the second air outlet upper wall 393, thereby causing the second blade assembly 316 to swing left and right.

Specifically, Figure 5A The air outlet device 500 shown will Figures 3A-3G The crank rocker mechanism in the air outlet device 300 shown is replaced by another transmission mechanism that converts rotational motion into reciprocating oscillation.

[0084] like Figure 5B-5CAs shown, the first transmission device 501 of the air outlet device 500 includes a first eccentric disc 514, a first transmission rack 524, a first transmission gear 532 and a bevel gear 534, wherein the first eccentric disc 514 can be rotated by the first output shaft 204. One end of the first transmission rack 524 has a first rack receiving groove 528, and the direction in which the first rack receiving groove 528 extends is arranged at a certain angle to the length direction of the first transmission rack 524, for example, arranged vertically.

The first transmission gear 532 has an outer tooth portion 526 and a transmission gear bevel tooth portion 527 arranged coaxially. The outer tooth portion 526 can mesh with the first rack portion 530 of the first transmission rack 524 , and the transmission gear bevel tooth portion 527 meshes with the bevel gear 534 for transmission.

[0085] When the first eccentric disc 514 rotates, the first rack accommodating groove 528 arranged at one end of the first transmission rack 524 can reciprocate and translate by eccentrically cooperating with the first eccentric protrusion 522 on the first eccentric disc 514, and the first transmission gear 532 is swung in a direction perpendicular to the first air outlet upper wall 391 through the meshing transmission of the first rack portion 530 of the first transmission rack 524 and the outer tooth portion 526 of the first transmission gear 532; the swing of the first transmission gear 532 can be converted into the swing of the bevel gear 534 in a direction perpendicular to the first air outlet side wall 390 through the meshing transmission of the transmission gear bevel tooth portion 527 and the bevel gear 534, and then transmitted and converted into the first swing axis 382 of the first blade group 315 swinging in a direction perpendicular to the first air outlet upper wall 390, thereby causing the first blade group 315 to swing up and down.

[0086] like Figure 5B and 5D As shown, the second transmission device 503 of the air outlet device 500 includes a second eccentric disk 516, a second transmission rack 504, and a second transmission gear 506, wherein the second transmission gear 506 is coaxially arranged with the second swing shaft 384 of the second blade group 316, and the second eccentric disk 516 can be rotated by the rotation drive of the second output shaft 206.

[0087] One end of the second transmission rack 504 has a second rack receiving groove 508, and the direction in which the second rack receiving groove 508 extends is arranged at a certain angle to the length direction of the second transmission rack 504, for example, arranged vertically.

The other end of the second transmission rack 504 is provided with a second rack portion 510, which can mesh with the second transmission gear 506 for transmission.

[0088] When the second eccentric disk 516 rotates, the second rack receiving groove 508 disposed at one end of the second transmission rack 504 can reciprocate by eccentrically cooperating with the second eccentric protrusion 502 on the second eccentric disk 516, and the second rack portion 510 on the other side of the second transmission rack 504 is meshed with the second transmission gear 506 to transmit, so that the second transmission gear 506 swings in a direction perpendicular to the second air outlet upper wall 393. The swing of the second transmission gear 506 can make the second swing shaft 384 of the second blade group 316 swing in a direction perpendicular to the second air outlet upper wall 393, so that the second blade group 316 swings left and right.

[0089] For those who have at least ordinary technical skills in this field, in some other embodiments, the first transmission device and the second transmission device (such as a crank rocker or an eccentric disc, a swing rack, a transmission gear mechanism) in the air outlet device 300 and the air outlet device 500 can also be replaced with each other and arranged crosswise.

[0090] Figure 6 To have Figure 2A-2B A perspective view of the vent arrangement system 600 of the clutch arrangement 200 is shown.

[0091] like Figure 6 As shown, the air outlet device system 600 includes a first clutch device 200 ′, a second clutch device 200 ″, a first air outlet device 300 ′ and a second air outlet device 300 ″, wherein each of the first clutch device 200 ′ and the second clutch device 200 ″ has a first output shaft and a second output shaft, respectively.

[0092] The first output shaft and the second output shaft of the first clutch device 200' can drive the first blade group of the first air outlet device 300' and the second air outlet device 300" through the first transmission device 602 and the second transmission device 604 respectively, and the first output shaft and the second output shaft of the second clutch device 200" can drive the second blade group of the second air outlet device 300' and the second air outlet device 300" through the third transmission device 606 and the fourth transmission device 608 respectively.

[0093] For those who have at least ordinary technical skills in this field, in some other embodiments, more than two clutch devices and more than two air outlet devices may be set in the air outlet device system 600 to achieve cross-driving or control of multiple air outlet devices by multiple clutch devices.

[0094] For those who have at least ordinary skills in the art, in some other embodiments, the air outlet device 300, the air outlet device 500 and the air outlet device system 600 of the present application can also be Figures 1A-1C The actuator arrangement 100 shown is driven.

[0095] Fig. 7A and 7B They are Figure 3F and 3G Zoomed view of the control system for blades M and N.

[0096] Fig. 7A and 7B The working principle of the blade control system shown is basically the same. Figure 7B The blade control system shown is taken as an example to introduce its working principle.

[0097] like Figure 3G and 7B As shown, the air outlet device 300 has a blade control system, which includes a first blade group 315, a first position detection device 370, a position detection device actuator 366 and a control device (not shown in the figure), wherein the first position detection device 370 has a first trigger switch 704, and can be one of a micro switch, a Hall sensor, a light signal position sensor or a sound signal position sensor. One end of the position detection device actuator 366 is fixedly connected to the first swing shaft 382, ​​and the other end extends outward in the radial direction to actuate the first trigger switch 704. The first trigger switch 704 has a protruding position and a recessed position. When the first trigger switch 704 is in the protruding position, the first trigger switch 704 protrudes from the upper surface 712 of the first position detection device 370 and is arranged opposite to the position detection device actuator 366.

[0098] The first blade group 315 can swing within a specific angle range, and the angle range includes a first swing boundary position (corresponding to Figure 7B The middle position detection device actuator 366 swings to a position in contact with the first trigger switch 704) and a second swing boundary position (corresponding to Figure 7B), the specific angle range is defined by the first swing boundary position and the second swing boundary position. Since the position detection device actuator 366 is coaxially fixedly arranged with the first swing shaft 382, ​​the swing of the first blade group 315 between the first swing boundary position and the second swing boundary position can be reflected as the swing of the position detection device actuator 366. When the air outlet blade 315 swings to the first swing boundary position, the position detection device actuator 366 contacts the first trigger switch 704 and presses the first trigger switch 704 from the protruding position to the recessed position, thereby the first trigger switch 704 causes the first position detection device 370 to generate a first boundary position signal to indicate that the first blade group 315 swings to the first swing boundary position.

[0099] The control device is configured to receive an air outlet blade position signal set by a user. According to the air outlet blade position signal, the control device can obtain the angle at which the blade group needs to swing from the swing boundary position.

[0100] If the first blade group 315 is not at the first swing boundary position when the outlet blade position signal is received, the control device controls the first blade group 315 to swing until the first blade group 315 swings to the first swing boundary position. If the first blade group 315 is exactly at the first swing boundary position, or has swung to the first swing boundary position when the outlet blade position signal is received, the first trigger switch 704 is triggered, and the first position detection device 370 immediately generates a first boundary position signal. At this time, the control device can control the first blade group 315 to swing a corresponding angle according to the swing angle calculated based on the outlet blade position signal set by the user and the first boundary position signal from the first position detection device 370, until the first blade group 315 swings to the blade position set by the user, and then stop the swing of the first blade group 315. In this way, no matter where the first blade group 315 is, as long as the outlet blade position signal set by the user is received, the first blade group 315 can be accurately controlled to swing to the blade position set by the user.

[0101] Same working principle as above, Figure 3F and 7A The blade control system shown includes a second blade assembly 316, a second position detection device 372, a position detection device actuator 368, and a control device (not shown in the figure), wherein the second position detection device 372 has a second trigger switch 702, and can be one of a micro switch, a Hall sensor, a light signal position sensor, or a sound signal position sensor. The position detection device actuator 368 can trigger the second trigger switch 702 of the second position detection device 372, so that the second position detection device 372 generates a boundary position signal, thereby indicating that the second blade assembly 316 swings to the boundary position.

[0102] When the air outlet blade position signal is received, if the second blade group 316 is not at the second swing boundary position, the control device controls the second blade group 316 to swing until the second blade group 316 swings to the second swing boundary position. If the second blade group 316 is exactly at the second swing boundary position, or has swung to the second swing boundary position when the air outlet blade position signal is received, the second trigger switch 702 is triggered, and the second position detection device 372 immediately generates a second boundary position signal. At this time, the control device can control the second blade group 316 to swing to a corresponding angle based on the swing angle calculated according to the air outlet blade position signal set by the user and the second boundary position signal from the second position detection device 372, until the second blade group 316 swings to the blade position set by the user, and then stop the swing of the second blade group 316.

[0103] The actuator device, clutch device and air outlet device of the present application have the following beneficial technical effects compared with the prior art:

[0104] The output shafts of the actuator device or clutch device in the present application are arranged to extend upward at a certain distance from each other, so that the blade transmission device (such as crank rocker mechanism, eccentric disc, swing rack and transmission gear and other components) connected to the output shaft can be concentrated on the same plane (such as the upper surface of the air outlet chamber) or two planes with a small distance between them, that is, the swing of the left and right and upper and lower groups of blades is controlled respectively by the same input source, which is conducive to the rational use and simple control of the space of the air outlet control device. At the same time, by setting a blade position detection device, no matter where the blade is, the blade can be accurately controlled to swing to the set position.
