Description

Technical Field

[0001] The present invention relates to the field of vehicle air vents, and particularly to a driving device, an air-conditioning air vent assembly and a vehicle. Background Art

[0002] Existing electric vehicle air vents generally control the up-and-down air direction adjustment mechanism, left-and-right air direction adjustment mechanism, and air damper adjustment mechanism of the air vent separately through a driving member or an actuator, respectively controlling the up-and-down air outlet direction, left-and-right air outlet direction, and air damper opening and closing of the air vent. Obviously, the more functions the air vent itself has, the more complex the structure, the more components, the more driving members or actuators, and the higher the cost. At the same time, in order to accommodate each mechanism, the space required for the air vent will also increase. Therefore, how to integrate functions and reduce costs is a technical problem that needs to be solved currently. Summary of the Invention

Detailed implementation manners

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Embodiment, referring to the attached Figure 1-10 , a driving device for driving the first transmission mechanism 400 or the second transmission mechanism 600 in an air outlet assembly of an air conditioner. The driving device includes a housing 100, a driving actuator 200, and a clutch mechanism 300 provided in the housing 100; the clutch mechanism 300 includes an input shaft 310, a transmission disc 320, a clutch transmission part 330, a first output part 340, and a second output part 350;

[0028] A transmission disc 320 is sleeved outside the input shaft 310 and can rotate relative to the transmission disc 320; the input shaft 310 includes a shaft main body 311, and a first driving part 312 and a second driving part 313 distributed along the axial direction of the input shaft 310;

[0029] The transmission disc 320 is provided with a limiting part 321 that can limit the relative angle between the input shaft 310 and the transmission disc 320 to only change between a first angular position and a second angular position; specifically, the limiting part 321 includes a first limiting block 3211 and a second limiting block 3212. When the first driving part 312 or the second driving part 313 of the input shaft 310 abuts against the first limiting block 3211, the position of the input shaft 310 relative to the transmission disc 320 is the first angular position; when the first driving part 312 or the second driving part 313 of the input shaft 310 abuts against the second limiting block 3212, the position of the input shaft 310 relative to the transmission disc 320 is the second angular position;

[0030] The clutch transmission member 330 is rotatably arranged on the cylinder of the transmission disc 320, and includes a first transmission part 331 and a second transmission part 332 axially distributed along the input shaft 310; the first transmission part 331 of the clutch transmission member 330 can be connected to the first driving part 312 of the input shaft 310, and the second transmission part 332 can be connected to the second driving part 313 of the input shaft 310. The clutch transmission member 330 can rotate around its own axis under the drive of the input shaft 310. The clutch transmission member 330 has a first clutch position that can be linked with the first output member 340 and a second clutch position that can be linked with the second output member 350;

[0031] While the input shaft 310 rotates between the first angular position and the second angular position relative to the transmission disc 320, it can drive the clutch transmission member 330 to rotate between the first clutch position and the second clutch position; specifically, when the input shaft 310 rotates relative to the transmission disc 320 towards the first angular position, the first driving part 312 abuts against the first transmission part 331 and drives the clutch transmission member 330 to rotate towards the first clutch position; when the input shaft 310 rotates relative to the transmission disc 320 towards the second angular position, the second driving part 313 abuts against the second transmission part 332 and drives the clutch transmission member 330 to rotate towards the second clutch position;

[0032] The first output member 340 includes an annular first annular part 341, and the inner circumferential surface of the first annular part 341 has a first ratchet tooth 3411 surrounding the inner circumferential surface for one circle, and the first ratchet tooth 3411 can abut against and be linked with the first transmission part 331 of the clutch transmission member 330; the second output member 350 includes an annular second annular part 351, and the inner circumferential surface of the second annular part 351 has a second ratchet tooth 3511 surrounding the inner circumferential surface for one circle, and the second ratchet tooth 3511 can abut against and be linked with the second transmission part 332 of the clutch transmission member 330;

[0033] When the driving member drives the input shaft 310 to continuously rotate in the first direction, the clutch transmission member 330 is in its first clutch position and is connected to the first output member 340. The input shaft 310 drives the first output member 340 to rotate synchronously through the transmission disc 320 and the clutch transmission member 330, and the second output member 350 does not move;

[0034] When the driving member drives the input shaft 310 to continuously rotate in the second direction, the clutch transmission member 330 is in its second clutch position and is connected to the second output member 350. The input shaft 310 drives the second output member 350 to rotate synchronously through the transmission disc 320 and the clutch transmission member 330, and the first output member 340 does not move; the first direction is opposite to the second direction.

[0035] The working principle of the driving device in this embodiment:

[0036] When the driving member drives the input shaft 310 to rotate in the first direction (counterclockwise rotation in the attached drawings), that is, the input shaft 310 rotates relative to the transmission disk 320 to the first angular position. During this process, the first driving portion 312 of the input shaft 310 abuts against the first transmission portion 331 of the clutch transmission member 330 and drives the clutch transmission member 330 to rotate to the first clutch position; when the input shaft 310 is in the first angular position relative to the transmission disk 320, the first transmission portion 331 of the clutch transmission member 330 abuts and engages with the first ratchet tooth 3411 of the first output member 340, and the second transmission portion 332 of the clutch transmission member 330 is separated from the second ratchet tooth 3511 of the second output member 350; thereafter, the driving member drives the input shaft 310 to continuously rotate in the first direction. Since the input shaft 310, the transmission disk 320, the clutch transmission member 330, and the first output member 340 have formed a stable state, the input shaft 310 can drive the first output member 340 to rotate synchronously in the first direction through the transmission disk 320 and the clutch transmission member 330, while the second output member 350 does not move.

[0037] Similarly, when the driving member drives the input shaft 310 to rotate in the second direction (clockwise rotation in the attached drawings), that is, the input shaft 310 rotates relative to the transmission disk 320 to the second angular position. During this process, the second driving portion 313 of the input shaft 310 abuts against the second transmission portion 332 of the clutch transmission member 330 and drives the clutch transmission member 330 to rotate to the second clutch position; when the input shaft 310 is in the second angular position relative to the transmission disk 320, that is, the second transmission portion 332 of the clutch transmission member 330 abuts and engages with the second ratchet tooth 3511 of the second output member 350, and the first transmission portion 331 of the clutch transmission member 330 is separated from the first ratchet tooth 3411 of the first output member 340; thereafter, the driving member drives the input shaft 310 to continuously rotate in the second direction. Since the input shaft 310, the transmission disk 320, the clutch transmission member 330, and the second output member 350 have formed a stable state, the input shaft 310 can drive the second output member 350 to rotate synchronously in the second direction through the transmission disk 320 and the clutch transmission member 330, while the first output member 340 does not move.

[0038] In this embodiment, the number of the first driving portion 312 and the second driving portion 313 is 2, and they are arranged in a circular array centered on the rotation axis of the input shaft 310; correspondingly, the number of the clutch transmission members 330 is also 2, and they are arranged in a circular array centered on the rotation axis of the transmission disk 320. The first driving portion 312, the second driving portion 313, and the clutch transmission members 330 are all arranged in a circular array, and the multiple arrangements can improve the transmission stability of the clutch mechanism 300.

[0039] In this embodiment, on the outer circumferential surface of the first annular portion 341 of the first output member 340, there is a first track portion 3412 with a closed track path that surrounds the outer circumferential surface for one circle. When the first output member 340 rotates in the first direction, the first track portion 3412 can drive the linear or rotational movement of its mating member; the second output member 350 further includes an end face portion 352 disposed opposite to the first output member 340, and the end face portion 352 has a second track portion 3521 with a closed track path that is formed around the axis. When the second output member 350 rotates in the second direction, the second track portion 3521 can drive the linear or rotational movement of its mating member. In addition, in this embodiment, the diameter of the inner circumferential surface of the first annular portion 341 is larger than the diameter of the outer circumferential surface of the second annular portion 351, and the second output member 350 is at least partially located in the cavity formed by the inner circumferential surface of the first output member 340, so that the structure of the clutch mechanism 300 can be made as compact as possible.

[0040] In another embodiment, the first output member 340 includes an end face disposed opposite to the second output member 350, and the first track portion 3412 can be disposed on this end face. The track path of the first track portion 3412 is closed and is formed around the axis of the first output member 340; while the second track portion 3521 can be disposed on the outer circumferential surface of the second annular portion 351 of the second output member 350, and the track path of the second track portion 3521 is closed and surrounds the outer circumferential surface for one circle; the setting positions of the first track portion and the second track portion can be determined according to the specific structure of the air outlet.

[0041] This embodiment further provides an air-conditioning air outlet assembly, which includes the driving device as described above, and further includes a first transmission mechanism 400, a first air direction adjusting mechanism 500, a second transmission mechanism 600, and a second air direction adjusting mechanism 700; the first output member 340 of the driving device is linked and connected with the first air direction adjusting mechanism 500 through the first transmission mechanism 400, and the first air direction adjusting mechanism 500 is used to adjust the left-right air outlet direction of the air-conditioning air outlet assembly; the second output member 350 of the driving device is linked and connected with the second air direction adjusting mechanism 700 through the second transmission mechanism 600; the second air direction adjusting mechanism 700 is used to adjust the up-down air outlet direction of the air-conditioning air outlet assembly.

[0042] Furthermore, it further includes a first potentiometer and a second potentiometer for detecting the rotation angle; the first air direction adjusting mechanism 500 includes a first air guiding vane, and both ends of the rotating shaft of the first air guiding vane are respectively connected with the first transmission mechanism 400 and the first potentiometer; the second air direction adjusting mechanism 700 includes a second air guiding vane, and both ends of the rotating shaft of the second air guiding vane are respectively connected with the second transmission mechanism 600 and the second potentiometer; through the potentiometer, the current angle of the air guiding vane can be obtained in real time, avoiding the deviation of the angle of the air guiding vane or the accumulation of errors caused by the back-and-forth switching of the first output member 340 and the second output member 350 of the driving device, and making it impossible to know the actual angle of the air guiding vane.

[0043] This embodiment also provides a vehicle, including the air outlet assembly as described above.
