Description

Technical Field

[0001] The present invention relates to the field of vehicle air outlets, and in particular to a driving device, an air-conditioning air outlet assembly and a vehicle. Background Art

The air-conditioning outlet and vehicle equipped with the driving device of the present invention can save the cost of the driving member and thus reduce the overall cost of the air-conditioning outlet.

DETAILED DESCRIPTION

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

[0027] For example, see the attached Figure 1-10 A driving device is used to drive a first transmission mechanism 400 or a second transmission mechanism 600 in an air-conditioning outlet assembly, the driving device comprising a housing 100, a driving actuator 200 and a clutch mechanism 300 disposed in the housing 100; the clutch mechanism 300 comprises an input shaft 310, a transmission disc 320, a clutch transmission member 330, a first output member 340 and a second output member 350; The input shaft 310 is provided with a transmission disk 320 on its outer sleeve and can rotate relative to the transmission disk 320 ; the input shaft 310 includes a shaft body 311 and a first driving part 312 and a second driving part 313 distributed along the axial direction of the input shaft 310 ; The transmission disc 320 has a limiting portion 321 which can limit the relative angle between the input shaft 310 and the transmission disc 320 to change only between a first angle position and a second angle position; specifically, the limiting portion 321 includes a first limiting block 3211 and a second limiting block 3212. When the first driving portion 312 or the second driving portion 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 angle position; when the first driving portion 312 or the second driving portion 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 angle position; The clutch transmission member 330 is rotatably disposed on a cylinder on the transmission disk 320, and includes a first transmission portion 331 and a second rotation portion 332 distributed along the axial direction of the input shaft 310; the first transmission portion 331 of the clutch transmission member 330 can be connected to the first driving portion 312 of the input shaft 310, and the second transmission portion can be connected to the second driving portion 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, and the clutch transmission member 330 has a first clutch position that can be linked to the first output member 340 and a second clutch position that can be linked to the second output member 350; When the input shaft 310 rotates relative to the transmission disc 320 between the first angular position and the second angular position, the clutch transmission member 330 can be driven 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 toward the first angular position, the first driving portion 312 abuts against the first transmission portion 331 and drives the clutch transmission member 330 to rotate toward the first clutch position; when the input shaft 310 rotates relative to the transmission disc 320 toward the second angular position, the second driving portion 313 abuts against the second transmission portion and drives the clutch transmission member 330 to rotate toward the second clutch position; The first output member 340 includes a first annular portion 341, on the inner surface of which there are first ratchet teeth 3411 surrounding the inner surface, and the first ratchet teeth 3411 can be in contact with the first transmission portion 331 of the clutch transmission member 330; the second output member 350 includes a second annular portion 351, on the inner surface of which there are second ratchet teeth 3511 surrounding the inner surface, and the second ratchet teeth 3511 can be in contact with the second transmission portion of the clutch transmission member 330; When the driving member drives the input shaft 310 to rotate continuously in the first direction, the clutch transmission member 330 is in its first clutch position and connected to the first output member 340. The input shaft 310 drives the first output member 340 to rotate synchronously through the transmission plate 320 and the clutch transmission member 330, and the second output member 350 does not move. When the driving member drives the input shaft 310 to rotate continuously in the second direction, the clutch transmission member 330 is in its second clutch position and connected to the second output member 350. The input shaft 310 drives the second output member 350 to rotate synchronously through the transmission plate 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.

[0028] The working principle of the driving device in this embodiment: When the driving member drives the input shaft 310 to rotate in the first direction (counterclockwise in the figure), that is, the input shaft 310 rotates to the first angular position relative to the transmission disk 320, in 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 at the first angular position relative to the transmission disk 320, the first transmission portion 331 of the clutch transmission member 330 abuts against the first transmission portion 331 of the first output member 340. The ratchet 3411 is abutted and engaged, and the second transmission part of the clutch transmission member 330 is separated from the second ratchet 3511 of the second output member 350; thereafter, the driving member drives the input shaft 310 to rotate continuously in the first direction. Since the input shaft 310, the transmission plate 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 plate 320 and the clutch transmission member 330, while the second output member 350 does not move; Similarly, when the driving member drives the input shaft 310 to rotate in the second direction (clockwise in the figure), that is, the input shaft 310 rotates to the second angular position relative to the transmission plate 320, in this process, the second driving portion 313 of the input shaft 310 abuts against the second transmission portion 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 at the second angular position relative to the transmission plate 320, that is, the second transmission portion of the clutch transmission member 330 abuts against the second transmission portion of the second output member 350, The ratchet 3511 is abutted and engaged, and the first transmission part 331 of the clutch transmission member 330 is separated from the first ratchet 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 plate 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 plate 320 and the clutch transmission member 330, while the first output member 340 does not move.

[0029] In this embodiment, the number of the first driving part 312 and the second driving part 313 is 2, and they are arranged in a circular array with the rotation axis of the input shaft 310 as the center; correspondingly, the number of the clutch transmission member 330 is also 2, and they are arranged in a circular array with the rotation axis of the transmission plate 320 as the center. The first driving part 312, the second driving part 313 and the clutch transmission member 330 are all distributed in a circular array, which can improve the transmission stability of the clutch mechanism 300.

[0030] In this embodiment, the first annular portion 341 of the first output member 340 has a first track portion 3412 on the outer ring surface with a closed track path and surrounding the outer ring surface. When the first output member 340 rotates in the first direction, the first track portion 3412 can drive the linear or rotational movement of the counterpart. The second output member 350 also includes an end face portion 352 disposed away from the first output member 340. The end face portion 352 has a second track portion 3521 formed around the axis with a closed track path. When the second output member 350 rotates in the second direction, the second track portion 3521 can drive the linear or rotational movement of the counterpart. In addition, in this embodiment, the diameter of the inner ring surface of the first annular portion 341 is larger than the diameter of the outer ring surface of the second annular portion 351. The second output member 350 is at least partially located in the cavity formed by the inner ring surface of the first output member 340, so that the structure of the clutch mechanism 300 can be as compact as possible.

[0031] In another embodiment, the first output member 340 includes an end face arranged away from the second output member 350, and the first track portion 3412 can be arranged on the end face, and the track path of the first track portion 3412 is closed and formed around the axis of the first output member 340; and the second track portion 3521 can be arranged on the outer ring 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 ring surface; 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.

[0032] The present embodiment also provides an air-conditioning air outlet assembly, including the driving device as described above, and also including a first transmission mechanism 400, a first wind direction adjustment mechanism 500, a second transmission mechanism 600, and a second wind direction adjustment mechanism 700; the first output member 340 of the driving device is linked to the first wind direction adjustment mechanism 500 through the first transmission mechanism 400, and the first wind direction adjustment mechanism 500 is used to adjust the left and right air outlet direction of the air-conditioning air outlet assembly; the second output member 350 of the driving device is linked to the second wind direction adjustment mechanism 700 through the second transmission mechanism 600; the second wind direction adjustment mechanism 700 is used to adjust the up and down air outlet direction of the air-conditioning air outlet assembly.

[0033] Furthermore, it also includes a first potentiometer and a second potentiometer for detecting the rotation angle; the first wind direction adjustment mechanism 500 includes a first air guide blade, and the two ends of the rotating shaft of the first air guide blade are respectively connected to the first transmission mechanism 400 and the first potentiometer; the second wind direction adjustment mechanism 700 includes a second air guide blade, and the two ends of the rotating shaft of the second air guide blade are respectively connected to the second transmission mechanism 600 and the second potentiometer; the current angle of the air guide blade can be obtained in real time through the potentiometer, avoiding the deviation of the angle of the air guide blade or the accumulation of errors when the first output member 340 and the second output member 350 of the driving device are switched back and forth, so that the actual angle of the air guide blade cannot be known.
