[0028] a second driving structure connected with the second driving rod and the second driving member, and being adapted to drive the second driving rod to move relative to the air outlet shell in a direction perpendicular to the second driving rod and the axis of the second driving shaft through the second driving structure when the first driving member rotates with the input shaft.

[0029] In the second aspect, the application provides an air outlet assembly comprising the single-motor driving mechanism for the air outlet.

[0030] Compared with the prior art, the technical scheme of the application has at least the following beneficial technical effects:

[0031] 1、The application sets an input shaft, a first driving member and a second driving member, the first driving member and the second driving member are connected with 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 rotation of the first driving member is transmitted to the corresponding blade through a first transmission mechanism, and the power of the rotation of the second driving member is transmitted to the corresponding blade through a second transmission mechanism, so as to realize the purpose of controlling the rotation of different blades of the air outlet. Therefore, the control of the rotation of different blades of the air outlet can be realized by switching the rotation direction of the input shaft, and then only one motor needs to be set, and the rotation of different blades of the air outlet is controlled by controlling the forward and reverse rotation of the motor, so as to reduce the number of motors, reduce the cost of motors and reduce the space occupied by the motors.

[0032] 2、The first transmission structure of the application realizes the one-way transmission function through the cooperation of the first transmission ring and the first elastic member. The first elastic member is initially located at the locking position. When the input shaft rotates in the direction opposite to the first rotation direction, the first protrusion abuts against the first movable end of the first elastic member to make the first movable end bend in the first rotation direction against the elastic force of the first elastic member, that is, the first elastic member bends from the locking position to the unlocking position. At this time, the first movable end moves close to the input shaft, and when the interval between the first movable end and the inner wall of the first transmission ring can allow the first protrusion to pass through, the first elastic member is in the unlocking position, and the first protrusion can pass through 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 protrusion abuts against the first elastic member, and the first protrusion applies a force to the first movable end of the first elastic member in the direction opposite to the first rotation direction. The force makes the first movable end bend in the direction opposite to the first rotation direction, and since the first movable end is limited to bend in the direction, the first movable end applies a force to the first protrusion in the same direction as the first rotation direction, so that the first elastic member drives the first protrusion to move in the first rotation direction, and then the first transmission ring and the first driving member rotate with the input shaft. That is, the one-way transmission function is realized through the cooperation of the first protrusion and the first elastic member on the first transmission ring and the inner wall thereof, which is simple in structure and low in cost.

[0033] 3、The first elastic member is designed to move away from the input shaft when the first movable end bends in the direction opposite to the first rotation direction. When the first movable end is at the locking position, the first movable end cannot move away from the input shaft because it abuts against the inner wall of the first transmission ring, and the bending of the first movable end in the direction opposite to the first rotation direction is limited, so that the purpose of limiting the bending of the first movable end in the direction opposite to the first rotation direction is achieved without the need for other structural members, which is simple in structure, reduces the processing difficulty and cost.

[0044] For the purpose of clarity, the present application will be described in greater detail below with reference to the accompanying drawings. The embodiments of the present application are shown in the drawings. However, the present application can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and fully convey the scope of the application to those skilled in the art.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0046] It will be understood that the spatially relative terms "beneath", "below", "lower", "under", "above", "upper" and the like, can be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures.

[0049] Reference will now be made to Figures 1-7As shown, the embodiment of the present application provides a single motor driving mechanism for an air outlet, which comprises a motor 1, an input shaft 2, a first driving member 3, a second driving member 4, a first transmission mechanism 7 and a second transmission mechanism 8. The output shaft of the motor 1 is coaxially fixed with the input shaft 2. The first driving member 3 and the second driving member 4 are sleeved on the input shaft 2. The first driving member 3 and the second driving member 4 can rotate relative to the input shaft 2 around the axis of the input shaft 2. The first driving member 3 is connected with the input shaft 2 through a first one-way transmission structure 5. The second driving member 4 is connected with the input shaft 2 through a second one-way transmission structure 6. When the input shaft 2 rotates in a first rotating direction around its own axis, the first driving member 3 is driven to rotate with the input shaft 2 through the first one-way transmission structure 5, and the second driving member 4 does not rotate with the input shaft 2. When the input shaft 2 reversely rotates, the second driving member 4 is driven to rotate with the input shaft 2 through the second one-way transmission structure 6, and the first driving member 3 does not rotate with the input shaft 2. The first transmission mechanism 7 and the second transmission mechanism 8 are connected with 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 be connected 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.

[0050] With reference to Figures 2-3 As shown, in order to realize the function that the output power of the input shaft 2 is transmitted 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 comprises a first transmission ring 51 and a first elastic member 52. The first transmission ring 51 is fixed with the first driving member 3 and coaxially surrounds the outside of the input shaft 2. The first elastic member 52 is arranged on the inside of the first transmission ring 51. The first elastic member 52 comprises a first connecting end 521 and a first movable end 522. The first connecting end 521 is fixed with the input shaft 2. 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 comprises a locking position which abuts against the inner wall of the first transmission ring 51. The first movable end 522 can be bent to an unlocking position which is spaced apart from the inner wall of the first transmission ring 51 in the first rotating direction from the locking position by overcoming the elastic force of the first elastic member 52. The first movable end 522 is limited to bend in the direction opposite to the first rotating direction at the locking position. A first protrusion 511 is arranged on the inner wall of the first transmission ring 51, which is adapted to drive the first movable end 522 to bend to the unlocking position from the locking position in the first rotating direction when the input shaft 2 rotates in the direction opposite to the first rotating direction.

[0051] With reference to Figure 3As shown, specifically, the first elastic member 52 is arranged such that when the first movable end 522 is bent in the direction opposite to the first rotation direction from the locking position, the first movable end 522 moves away from the input shaft 2. Thus, when the first movable end 522 is in the locking position, the first movable end 522 cannot move away from the input shaft 2 due to the abutment between the first movable end 522 and the inner wall of the first transmission ring 51, and the bending of the first movable end 522 in the direction opposite to the first rotation direction is limited, thereby achieving the purpose of limiting the bending of the first movable end 522 in the direction opposite to the first rotation direction from the locking position without the need for other structural members, and the structure is simple, and the processing difficulty and cost are reduced.

[0052] Referring to Figure 3 As shown, further, to achieve the purpose of moving away from the input shaft 2 when the first movable end 522 is bent in the direction opposite to the first rotation direction from the locking position, the first elastic member 52 is arranged such that the projection thereof in the plane perpendicular to the axis of the input shaft 2 is arc-shaped and the outer 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 is bent in the first rotation direction, the bending degree of the arc shape becomes larger, the distance between the first movable end 522 and the first connecting end 521 becomes smaller, i.e., the first movable end 522 moves closer to the input shaft 2, and when the first movable end 522 is bent in the opposite direction, the bending degree of the arc shape becomes smaller, the distance between the first movable end 522 and the first connecting end 521 becomes larger, i.e., the first movable end 522 moves away from the input shaft 2. Thus, the abutment between the first movable end 522 and the inner wall of the first transmission ring 51 can limit the bending of the first movable end 522 in the direction opposite to the first rotation direction from the locking position, and the first elastic member 52 drives the first protrusion 511 to rotate together, thereby achieving the function of rotating the first driving member 3 with the input shaft 2.

[0053] Referring to Figure 3 As shown, further, the first transmission structure includes at least two first elastic members 52, and the at least two first elastic members 52 are distributed along the circumference of the input shaft 2. Moreover, a plurality of first protrusions 511 are arranged on the inner wall of the first transmission ring 51, and the plurality of first protrusions 511 are distributed along the circumference of the first transmission ring 51, and the distance between adjacent two first protrusions 511 can accommodate 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 elastic sheet and ensure that the first movable end 522 of the first elastic member 52 abuts against the first protrusion 511 when the input shaft 2 rotates in the first rotation direction, one side of the two sides in the first rotation direction is an outer convex arc surface, and the other side is an inner concave arc surface, and the inner concave arc surface and the outer convex arc surface are distributed along the first rotation direction.

[0054] Referring to Figure 2 and Figure 4As shown, the second one-way transmission structure 6 comprises a second transmission ring 61 and a second elastic member 62. The second transmission ring 61 is fixed coaxially around the input shaft 2 outside the second transmission ring 61. The second elastic member 62 is arranged inside the second transmission ring 61. The second elastic member 62 comprises 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 is spaced apart from the input shaft 2 in the radial direction of the input shaft 2. The second movable end 622 comprises a locking position abutting against the inner wall of the second transmission ring 61. The second movable end 622 can be bent to an unlocking position spaced apart from the inner wall of the second transmission ring 61 from the locking position against the elastic force of the second elastic member 62 in the direction opposite to the first rotation direction. The second movable end 622 is limited to bend 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. When the input shaft 2 rotates in the first direction, the second protrusion 611 drives the second movable end 622 to bend from the locking position to the unlocking position in the direction opposite to the first rotation direction.

[0055] Referring to Figure 4 As shown, specifically, the second elastic member 62 is arranged to move away from the input shaft 2 when the second movable end 622 bends in the first rotation direction from the locking position. When the second movable end 622 is at the locking position, the second movable end 622 cannot move away from the input shaft 2 because the second movable end 622 abuts against the inner wall of the second transmission ring 61. Thus, the second movable end 622 is limited to bend in the first rotation direction, achieving the purpose of limiting the second movable end 622 to bend in the first rotation direction without the need of other structural members, which is simple in structure and reduces the processing difficulty and cost.

[0056] Referring to Figure 4 As shown, further, to achieve the purpose of moving away from the input shaft 2 when the second movable end 622 bends in the first rotation direction from the locking position, the second elastic member 62 is arranged to have an arc-shaped projection in a plane perpendicular to the axis of the input shaft 2 with the convex side facing the first rotation direction. When the second movable end 622 bends in the direction opposite to the first rotation direction, the bending degree of the arc-shaped second elastic member 62 increases, and the distance between the second movable end 622 and the second connecting end 621 decreases, i.e. the second movable end 622 moves closer to the input shaft 2. When the second movable end 622 bends in the first rotation direction, the bending degree of the arc-shaped second elastic member 62 decreases, and the distance between the second movable end 622 and the second connecting end 621 increases, i.e. the second movable end 622 moves away from the input shaft 2. Thus, the second movable end 622 is limited to bend in the first rotation direction from the locking position by abutting against the inner wall of the second transmission ring 61, and the second protrusion 611 is driven to rotate together by the second elastic member 62, achieving the function of rotating the second driving member 4 together with the input shaft 2.

[0057] Referring to Figure 4As shown, further, the second transmission structure includes at least two second elastic members 62, which are distributed along the circumference of the input shaft 2. Moreover, a plurality of second protrusions 611 are arranged on the inner wall of the second transmission ring 61, which are distributed along the circumference of the second transmission ring 61, and the distance between two adjacent second protrusions 611 can accommodate 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 elastic sheet, and 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 is kept in contact with the first protrusion 511, one side of the two sides in the first rotation direction is an outward convex arc surface, and the other side is an inward concave arc surface. The outward convex arc surface and the inward concave arc surface are distributed along the first rotation direction.

[0058] Referring to Figures 3-4 As shown, in this embodiment, two first elastic members 52 and two second elastic members 62 are arranged, 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 arranged in a cylindrical shape parallel to the axis of the input shaft 2. The first driving member 3 and the second driving member 4 are both arranged in a cylindrical shape coaxial with the input shaft 2, the first transmission ring 51 is integrally formed with the first driving member 3, and the second driving member 4 and the second transmission ring 61 are integrally formed.

[0059] Therefore, through the above structure, when the input shaft 2 rotates in two different directions, the purpose of driving one of the first driving member 3 and the second driving member 4 to rotate synchronously can be achieved. When the input shaft 2 is fixed with the motor 1 output shaft, the first driving member 3 or the second driving member 4 can be driven to rotate by the motor 1 forward or reverse rotation.

[0060] Referring to 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 arranged coaxially with the rotating shaft of the corresponding blade, the first rack 72 is engaged with the driving gear 71 and can move relative to the air outlet housing in the length direction, and the first driving structure connects the first rack 72 and the first driving member 3, and is suitable for driving the first rack 72 to move relative to the air outlet housing in the length direction through the first driving structure when the first driving member 3 rotates with the input shaft 2.

[0061] Referring to Figure 5As shown in the figure, the length direction of the first rack 72 is 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. The drive structure includes the first drive shaft 73 and the first drive rod 74. The first drive shaft 73 is parallel to the axis of the input shaft 2, and the first drive shaft 73 is connected to the first driving member 3 and is distributed in the radial direction of the input shaft 2. The length direction of the first drive rod 74 is perpendicular to the length direction of the first rack 72 and the axis of the input shaft 2. The first drive slot 741 is formed in the length direction of the first drive rod 74 on one side of the input shaft 2 in the axial direction. The first drive shaft 73 is embedded in the first drive slot 741 and can move in the length direction of the first drive slot 741 relative to the first drive rod 74.

[0062] Referring to Figure 5 As shown in the figure, specifically, the first drive shaft 73 is eccentrically connected to the first driving member 3. When the first driving member 3 rotates with the input shaft 2, the first driving member 3 rotates around the axis of the input shaft 2. In the process of rotation, the first drive shaft 73 is displaced in the length direction of the first rack 72 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 slot 741 and the rotation of the first drive rod 74 relative to the first drive rod 74. Therefore, the rotation of the first driving member 3 drives the corresponding blade to move in the length direction relative to the air outlet shell through the cooperation of the first drive shaft 73 and the first drive rod 74. The first rack 72 drives the driving gear 71 to rotate, thereby controlling the rotation of the corresponding blade. 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 is achieved.

[0063] Referring to Figure 5 As shown in the figure, and further, a first damper 9 is provided for connection to the air outlet shell and connection with the first rack 72. When the first rack 72 moves in the length direction relative to the air outlet shell, it overcomes the damping force of the first damper 9.
