[0014] In a second aspect, the present application provides an air outlet assembly, comprising a single motor drive mechanism for an air outlet as described above.

[0015] Compared with the prior art, the technical solution of the present application has at least the following beneficial technical effects: 1. The present application sets an input shaft and a first driving member and a second driving member, and the first driving member and the second driving member are connected to the input shaft through a first one-way transmission structure and a second one-way transmission structure respectively, so that when the input shaft rotates in two different directions, one of the first driving member and the second driving member is driven to rotate synchronously, and the power of the first driving member to rotate is transmitted to the corresponding blade through the first transmission mechanism, and the power of the second driving member to rotate is transmitted to the corresponding blade through the second transmission mechanism, so as to achieve the purpose of controlling the rotation of different blades at the air outlet. Therefore, the control of the rotation of different blades at the air outlet can be achieved by switching the rotation direction of the input shaft, and then only one motor needs to be set, and the rotation of different blades at the air outlet is controlled by controlling the forward and reverse rotation of the motor, thereby reducing the number of motors, reducing the cost of the motor and reducing the space occupied by the motor.

[0016] 2. The first transmission structure of the present application realizes a one-way transmission function through the cooperation of the first transmission ring and the first elastic member. The first elastic member is initially located in a locked position. When the input shaft rotates in a direction opposite to the first rotation direction, the first protrusion abuts against the first movable end of the first elastic member so that the first movable end overcomes the elastic force of the first elastic member and bends in the first rotation direction, that is, the first elastic member bends from the locked position to the unlocked position. At this time, the first movable end moves close to the input shaft until the gap between the first movable end and the inner wall of the first transmission ring is large enough for the first protrusion to pass through. At this time, the first elastic member is in an unlocked position, and the first protrusion can pass over the first elastic member. Therefore, the first transmission ring and the first driving member do not rotate with the input shaft. When the input shaft rotates in the first rotation direction, the first projection abuts against the first elastic member, and the first projection applies a force opposite to the first rotation direction to the first movable end of the first elastic member, and the force causes the first movable end to bend in the direction opposite to the first rotation direction. Since the first movable end is restricted from bending in this direction, the first movable end applies a force in the same direction as the first rotation direction to the first projection, thereby driving the first projection to move in the first rotation direction through the first elastic member, and then causing the first transmission ring and the first driving member to rotate with the input shaft. That is, the function of one-way transmission is realized through the cooperation of the first projection on the first transmission ring and the inner wall thereof and the first elastic member, and the structure is simple and the cost is low.

[0017] 3. The present application designs the first elastic member so that when the first movable end bends from the locking position to the direction opposite to the first rotation direction, it moves away from the input shaft. When in the locking position, due to the abutment between the first movable end and the inner wall of the first transmission ring, the first movable end cannot move in the direction away from the input shaft, thereby restricting the first movable end from bending in the direction opposite to the first rotation direction, thereby achieving the purpose of restricting the first movable end from bending in the direction opposite to the first rotation direction. There is no need to set other structural members, the structure is simple, and the processing difficulty and cost are reduced. BRIEF DESCRIPTION OF THE DRAWINGS

The output shaft of the motor 1 is coaxially fixed with the input shaft 2, the first drive member 3 and the second drive member 4 are sleeved on the input shaft 2, the first drive member 3 and the second drive member 4 can both rotate relative to the input shaft 2 around the axis of the input shaft 2, the first drive member 3 is connected to the input shaft 2 through a first one-way transmission structure 5, and the second drive member 4 is connected to the input shaft 2 through a second one-way transmission structure 6. When the input shaft 2 rotates around its own axis in a first rotation direction, the first drive member 3 is driven to rotate with the input shaft 2 through the first one-way transmission structure 5, and the second drive member 4 does not rotate with the input shaft 2. When the input shaft 2 rotates in the opposite direction, the second drive member 4 is driven to rotate with the input shaft 2 through the second one-way transmission structure 6, and the first drive member 3 does not rotate with the input shaft 2. The first transmission mechanism 7 and the second transmission mechanism 8 are connected to the first driving member 3 and the second driving member 4 respectively. The first transmission mechanism 7 and the second transmission mechanism 8 are used to connect with different air outlet blades. When the first driving member 3 rotates with the input shaft 2, the corresponding blades are driven to rotate through the first transmission mechanism 7. When the second driving member 4 rotates with the input shaft 2, the corresponding blades are driven to rotate through the second transmission mechanism 8.

[0026] Reference Figure 2-3 As shown, in order to realize the function of transmitting the output power of the input shaft 2 to the first driving member 3 or the second driving member 4 through the first one-way transmission structure 5 and the second one-way transmission structure 6, the first one-way transmission structure 5 includes a first transmission ring 51 and a first elastic member 52. The first transmission ring 51 is fixed to the first driving member 3 and coaxially surrounds the outside of the input shaft 2; the first elastic member 52 is arranged on the inner side of the first transmission ring 51, and the first elastic member 52 includes a first connecting end 521 and a first movable end 522. The first connecting end 521 is fixed to the input shaft 2, and the first movable end 522 is spaced apart from the input shaft 2 in the radial direction of the input shaft 2. The first movable end 522 includes a locking position abutting against the inner wall of the first transmission ring 51. The first movable end 522 can be bent from the locking position to the first rotation direction to the unlocking position spaced apart from the inner wall of the first transmission ring 51 by overcoming the elastic force of the first elastic member 52, and the first movable end 522 is restricted from bending in the direction opposite to the first rotation direction at the locking position. A first protrusion 511 is provided on the inner wall of the first transmission ring 51 , which is suitable for driving the first movable end 522 to bend from a locking position to an unlocking position in the first rotation direction through the first protrusion 511 when the input shaft 2 rotates in a direction opposite to the first rotation direction.

[0027] Reference Figure 3As shown, specifically, the first elastic member 52 is configured so that when the first movable end 522 bends from the locking position to the direction opposite to the first rotation direction, it moves away from the input shaft 2. In this way, when the first movable end 522 is in the locking position, due to the abutment between the first movable end 522 and the inner wall of the first transmission ring 51, the first movable end 522 cannot move in the direction away from the input shaft 2, thereby restricting the first movable end 522 from bending in the direction opposite to the first rotation direction in the locking position, thereby achieving the purpose of restricting the first movable end 522 from bending in the direction opposite to the first rotation direction in the locking position, without setting other structural members, the structure is simple, and the processing difficulty and cost are reduced.

[0028] Reference Figure 3 As shown, further, in order to achieve the purpose of moving away from the input shaft 2 when the first movable end 522 bends from the locking position to the direction opposite to the first rotation direction, the first elastic member 52 is set to have an arc-shaped projection in a plane perpendicular to the axis of the input shaft 2 and the convex side faces the direction opposite to the first rotation direction. Due to the arc-shaped structure of the first elastic member 52, when the first movable end 522 bends to the first rotation direction, the degree of bending of the arc becomes larger, and the distance between the first movable end 522 and the first connecting end 521 becomes smaller, that is, it moves closer to the input shaft 2, and when the first movable end 522 bends to the opposite direction, the degree of bending of the arc becomes smaller, and the distance between the first movable end 522 and the first connecting end 521 becomes larger, that is, it moves away from the input shaft 2. In this way, the first movable end 522 can be abutted against the inner wall of the first transmission ring 51 to limit the first movable end 522 from bending from the locking position to the direction opposite to the first rotation direction, and then the first elastic member 52 drives the first protrusion 511 to rotate together, so as to achieve the function of making the first driving member 3 rotate with the input shaft 2.

[0029] Reference Figure 3 As shown, further, the first transmission structure includes at least two first elastic members 52, and at least two first elastic members 52 are spaced apart along the circumference of the input shaft 2. In addition, a plurality of first protrusions 511 are provided on the inner wall of the first transmission ring 51, and the plurality of first protrusions 511 are spaced apart along the circumference of the first transmission ring 51, and the distance between two adjacent first protrusions 511 can be embedded in the first movable end 522 of the first elastic member 52. In order to reduce the friction loss between the first protrusion 511 and the spring sheet, and to ensure that the first movable end 522 of the first elastic member 52 maintains abutment with the first protrusion 511 when the input shaft 2 rotates in the first rotation direction, one side is an outward convex arc surface, and the other side is an inward concave arc surface, and the inward concave arc surface and the outward convex arc surface are distributed along the first rotation direction.

[0030] Reference Figure 2 and Figure 4As shown, the second one-way transmission structure 6 includes a second transmission ring 61 and a second elastic member 62. The second transmission ring 61 is fixed to the second driving member 4 and coaxially surrounds the input shaft 2. The second elastic member 62 is arranged on the inner side of the second transmission ring 61. The second elastic member 62 includes a second connecting end 621 and a second movable end 622. The second connecting end 621 is fixed to the input shaft 2. The second movable end 622 and the input shaft 2 are spaced apart in the radial direction of the input shaft 2. The second movable end 622 includes a locking position abutting against the inner wall of the second transmission ring 61. The second movable end 622 can overcome the elastic force of the second elastic member 62 from the locking position and bend in the direction opposite to the first rotation direction to an unlocking position spaced apart from the inner wall of the second transmission ring 61. The second movable end 622 is restricted from bending in the first rotation direction at the locking position. A second protrusion 611 is arranged on the inner wall of the second transmission ring 61, which is suitable for driving the second movable end 622 to bend from the locking position to the direction opposite to the first rotation direction to the unlocking position through the second protrusion 611 when the input shaft 2 rotates in the first direction.

[0031] Reference Figure 4 As shown, specifically, the second elastic member 62 is configured to move the second movable end 622 away from the input shaft 2 when it bends from the locking position to the first rotation direction. In this way, when the second movable end 622 is in the locking position, due to the abutment between the second movable end 622 and the inner wall of the second transmission ring 61, the second movable end 622 cannot move in the direction away from the input shaft 2, thereby restricting the bending of the second movable end 622 in the first rotation direction, thereby achieving the purpose of restricting the bending of the second movable end 622 in the first rotation direction. There is no need to set other structural parts, the structure is simple, and the processing difficulty and cost are reduced.

[0032] Reference Figure 4 As shown, further, in order to achieve the purpose of moving away from the input shaft 2 when the second movable end 622 bends from the locking position to the first rotation direction, the second elastic member 62 is set to have an arc-shaped projection in a plane perpendicular to the axis of the input shaft 2 and the convex side faces the first rotation direction. Due to the arc-shaped structure of the second elastic member 62, when the second movable end 622 bends in the direction opposite to the first rotation direction, the bending degree of the arc becomes larger, and the distance between the second movable end 622 and the second connecting end 621 becomes smaller, that is, it moves closer to the input shaft 2, and when the second movable end 622 bends in the first rotation direction, the bending degree of the arc becomes smaller, and the distance between the second movable end 622 and the second connecting end 621 becomes larger, that is, it moves away from the input shaft 2. In this way, the second movable end 622 can be abutted against the inner wall of the second transmission ring 61 to limit the bending of the second movable end 622 from the locking position to the first rotation direction, and then the second elastic member 62 drives the second convex block 611 to rotate together, so as to achieve the function of making the second driving member 4 rotate with the input shaft 2.

[0033] Reference Figure 4As shown, further, the second transmission structure includes at least two second elastic members 62, and at least two second elastic members 62 are distributed at intervals along the circumference of the input shaft 2. In addition, a plurality of second protrusions 611 are provided on the inner wall of the second transmission ring 61, and the plurality of second protrusions 611 are distributed at intervals along the circumference of the second transmission ring 61, and the distance between two adjacent second protrusions 611 can be embedded in the second movable end 622 of the second elastic member 62. In order to reduce the friction loss between the second protrusion 611 and the spring sheet, and to ensure that when the input shaft 2 rotates in the direction opposite to the first rotation direction, the second movable end 622 of the second elastic member 62 maintains abutment with the first protrusion 511, one side of the two sides in the first rotation direction is a convex arc surface, and the other side is a concave arc surface, and the convex arc surface and the concave arc surface are distributed along the first rotation direction.

[0034] Reference Figure 3-4 As shown, in this embodiment, two first elastic members 52 and two second elastic members 62 are provided for illustration, and the first elastic member 52 and the second elastic member 62 are both elastic sheets, and in other embodiments, they can also be elastic rods. In order to improve the structural strength of the first movable end 522 and the second movable end 622, the first movable end 522 and the second movable end 622 are both set to be cylindrical and parallel to the axis of the input shaft 2. The first driving member 3 and the second driving member 4 are both set to be cylindrical and coaxial with the input shaft 2, the first transmission ring 51 and the first driving member 3 are integrally formed, and the second driving member 4 and the second transmission ring 61 are integrally formed.

[0035] Therefore, the above structure can achieve the purpose of driving one of the first driving member 3 and the second driving member 4 to rotate synchronously when the input shaft 2 rotates in two different directions. When the input shaft 2 and the output shaft of the motor 1 are fixed, the first driving member 3 or the second driving member 4 can be driven to rotate forward and reversely by the motor 1.

[0036] Reference Figure 1 and Figure 5 As shown, in order to achieve the purpose of driving the corresponding blade to rotate through the first transmission mechanism 7 when the first driving member 3 rotates with the input shaft 2, the first transmission mechanism 7 includes a driving gear 71, a first rack 72 and a first driving structure. The driving gear 71 is used to be coaxially fixed with the rotating shaft of the corresponding blade, the first rack 72 is meshed with the driving gear 71 and can be moved relative to the air outlet shell in the length direction, and the first driving structure connects the first rack 72 and the first driving member 3, which is suitable for driving the first rack 72 to move relative to the air outlet shell in the length direction through the first driving structure when the first driving member 3 rotates with the input shaft 2.

[0037] Reference Figure 5As shown, the length direction of the first rack 72 is set to be perpendicular to the length direction of the input shaft 2, and the axis of the first drive shaft 73 is parallel to the axis of the input shaft 2.

[0038] Reference Figure 5 As shown, specifically, the first drive shaft 73 is eccentrically connected to the first drive member 3. When the first drive member 3 rotates with the input shaft 2, the first drive member 3 rotates with the first drive member 3 around the axis of the input shaft 2. During the rotation, the first drive shaft 73 is displaced in the length direction of the first rack 72, so as to drive the first rack 72 to move in the length direction through the first drive rod 74. At the same time, the first drive shaft 73 is displaced in the length direction of the first drive rod 74, and the displacement is offset by the movement of the first drive rod 74 in the first drive groove 741 and the rotation relative to the first drive rod 74. Therefore, the first drive member 3 rotates through the first drive shaft 73 and the first drive rod 74 to drive the rack to move in the length direction relative to the air outlet housing, and the first rack 72 drives the driving gear 71 to rotate, thereby controlling the corresponding blade to rotate. The purpose of driving the corresponding blade to rotate through the first transmission mechanism 7 when the first drive member 3 rotates with the input shaft 2 is achieved.

[0039] Reference Figure 5 As shown, further, a first damper 9 is provided, and the first damper 9 is used to be connected to the air outlet housing and connected to the first rack 72. When the first rack 72 moves relative to the air outlet housing along the length direction, it overcomes the damping force of the first damper 9. Specifically, the first damper 9 adopts a rotary damper with a gear, which is fixed to the air outlet housing during installation, and the gear of the damper is meshed with the first rack 72, thereby providing a damping force when the first rack 72 moves, so that the first rack 72 moves smoothly.

[0040] Reference Figure 1 and Figure 6-7As shown, the second transmission mechanism 8 includes a second drive rod 81 and a second drive structure. The second drive rod 81 is provided with a second drive groove 811 along the length direction. The second drive groove 811 is provided with a second drive shaft 82 that can move relative to the second drive rod 81 along the length direction of the second drive groove 811.

The second drive shaft 82 is used to connect with the corresponding blade, and the axis of the second drive shaft 82 is parallel to the rotation axis of the corresponding blade and is spaced apart in the radial direction of the rotation axis. The second drive structure connects the second drive rod 81 and the second drive member 4, and is suitable for driving the second drive rod 81 to move relative to the air outlet housing in a direction perpendicular to the axes of the second drive rod 81 and the second drive shaft 82 through the second drive structure when the first drive member 3 rotates with the input shaft 2.

[0041] Reference Figure 6-7 As shown, when the second drive rod 81 moves relative to the air outlet housing in a direction perpendicular to the axes of the second drive rod 81 and the second drive shaft 82, the second drive shaft 82 is displaced in this direction, so that the second drive shaft 82 rotates around the corresponding blade shaft, and at this time, the displacement of the second drive shaft 82 in the length direction of the second drive rod 81 is offset by sliding and rotating in the second drive slot 811. The purpose of driving the corresponding blade to rotate through the second transmission mechanism 8 is achieved.

[0042] Reference Figure 6-7 As shown, specifically, in this embodiment, the axis of the second drive shaft 82 is perpendicular to the axis of the input shaft 2, that is, the two blade rotation axes of the air outlet are perpendicular to each other. The length direction of the second drive rod 81 and the axis of the second drive shaft 82 are both perpendicular to the input shaft 2. The second drive structure includes a second rack 83, a third drive rod 84 and a transmission gear 85. The length direction of the second rack 83 is parallel to the axis of the input shaft 2 and is fixed to the second drive rod 81. The length direction of the third drive rod 84 is parallel to the length direction of the second drive rod 81, and a third drive groove 841 is provided on the third drive rod 84 along the length direction. The axis of the transmission gear 85 is parallel to the axis of the second drive shaft 82 and can rotate relative to the air outlet housing, and a third drive shaft 86 is eccentrically connected to the transmission gear 85. The third drive shaft 86 is parallel to the axis of the transmission gear 85 and is embedded in the third drive groove 841. With this structure, when the transmission gear 85 rotates, the cooperation between the third drive shaft 86 and the third drive rod 84 can drive the second rack 83 to move in the length direction, thereby driving the second drive rod 81 to move and causing the second transmission shaft and the corresponding blade to rotate. In order to drive the transmission gear 85 to rotate through the second drive member 4, an end face gear 41 fixed to the second drive member 4 is provided outside the second drive member 4. The end face gear 41 is coaxial with the input shaft 2 and meshes with the transmission gear 85. When the second drive member 4 rotates with the input shaft 2, the transmission gear 85 is driven to rotate through the end face gear 41, thereby achieving the purpose of driving the corresponding blade to rotate.

[0043] Through the above arrangement, the rotation of different blades of the air outlet can be controlled by controlling the forward and reverse rotation of the motor 1, thereby reducing the number of motors 1, reducing the cost of the motor 1 and reducing the space occupied by the motor 1.

[0044] Reference Figure 6-7 As shown, further, a second damper 10 is provided, and the second damper is used to be connected to the air outlet housing and connected to the second blocking rack, and the second blocking rack overcomes the damping force of the second damper when it moves relative to the air outlet housing along the length direction. Specifically, the second damper also adopts a rotary damper with a gear, which is fixed to the air outlet housing during installation, and the gear of the second damper 10 is meshed with the second blocking rack, thereby providing a damping force when the second blocking rack moves, so that the second blocking rack moves smoothly.

[0045] Reference Figure 8 As shown, this embodiment also provides an air outlet assembly, which includes a housing 20, a blade group and a single motor drive mechanism for an air outlet as described above. Specifically, the blade group includes a plurality of transverse blades 30 and a longitudinal blade 40, the transverse blades 30 and the longitudinal blades 40 are rotatably connected to the housing through a rotating shaft, and the rotating shafts are perpendicular to each other, the plurality of transverse blades 30 are distributed at intervals along the axial direction of the rotating shaft of the longitudinal blade 40, and the plurality of transverse blades 30 are connected by a connecting rod, and the connecting rod is hinged to the plurality of transverse blades 30, so that when one transverse blade 30 is transferred, the plurality of transverse blades 30 are rotated synchronously through the connecting rod.

[0046] The single motor drive mechanism for the air outlet is arranged outside the housing 20, the first transmission structure connects the transverse blade 30 and the first driving member 3, and the second transmission structure connects the longitudinal blade 40 and the second driving member 4. Specifically, the driving gear 71 is coaxially fixed with the rotation axis of one transverse blade 30, and the second driving shaft 82 is fixed with the longitudinal blade 40 and the axis of the second driving shaft 82 is parallel to the rotation axis of the longitudinal blade 40, the second driving shaft 82 passes through the housing 20, and an arc groove is opened on the housing 20 for the second driving shaft 82 to rotate around the rotation axis of the longitudinal blade 40.

[0047] During installation, the motor 1 is fixedly mounted on the center console, and the transmission gear 85 is rotatably mounted on the center console. The motor 1 outputs power to the input shaft 2. When the input shaft 2 rotates along a first rotation direction, the transverse blades 30 are driven to rotate through the first transmission structure. When the motor 1 is reversed to make the input shaft 2 rotate in the opposite direction, the longitudinal blades 40 are driven to rotate through the second transmission structure, thereby controlling the rotation of two blades in different directions through one motor 1.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
