[0039] The driving mechanism 15 may be drivingly connected to any one of the first guide gear 111 , the second guide gear 112 and the rack 113 .

[0040] Exemplarily, the drive mechanism 15 includes a motor, and the motor shaft of the motor is connected to any one of the first guide gear 111, the second guide gear 112 and the rack 113 through a key transmission (couplings, set screws, etc. can fix any one of the first guide gear 111, the second guide gear 112 and the rack 113 on the motor shaft to achieve linkage with the motor shaft). In other examples, the drive mechanism 15 may also include a reducer, and the motor shaft of the motor is connected to the input end of the reducer through a key, and the output end of the reducer is connected to any one of the first guide gear 111, the second guide gear 112 and the rack 113 through a key.

[0041] Specifically, a plurality of meshing teeth are formed on both side surfaces of the rack 113 along the first direction X.

[0042] Optionally, connecting shafts are provided at both ends of the swing blade 12, and the connection between the connecting shaft and the swing blade 12 includes but is not limited to welding, screw connection, riveting, or integral molding by injection molding, etc. The connecting shaft at one end of the swing blade 12 is drivingly connected to the second guide gear 112, which can be, but is not limited to, a key connection, and the connecting shaft and the second guide gear 112 can also be made into an integrated structure.

[0043] Optionally, the pendulum blade 12 may be, but is not limited to, a strip-shaped structure. In one example, the pendulum blade 12 is a strip-shaped structure, and a cavity is formed inside the pendulum blade 12, which can reduce the weight of the pendulum blade 12, so that the pendulum blade 12 can rotate flexibly. The end of the pendulum blade 12 is connected to an end cap, and the end cap is fixedly connected to the pendulum blade 12, which may be, but is not limited to, screw connection, welding or bonding. The end cap is fixedly connected to a connecting shaft, and the axial direction of the connecting shaft is substantially the same as the length direction of the pendulum blade 12.

[0044] Optionally, the mounting seat 17 may be a plate-shaped structure or a shell structure, and may be configured according to actual needs. Figure 1 As shown, the mounting seat 17 includes a first seat body 171 and a second seat body 172 . The first seat body 171 and the second seat body 172 are buckled together and together define an accommodating cavity. The transmission mechanism 11 is disposed in the accommodating cavity.

[0045] According to a wind swing device 10 of the utility model, a second guide gear 112 and a first guide gear 111 are arranged on both sides of the gear along the first direction X, and a first guide gear 111 is arranged between the two second guide gears 112 along the length direction of the rack 113, which can limit the swing of the rack 113 so that the rack 113 can move along its own length direction, so that the rack 113 can work more smoothly, and through the movement of the rack 113, multiple second guide gears 112 can be driven to rotate at the same time, so that multiple swing blades 12 can rotate at the same time, realizing the linkage of multiple swing blades 12. Compared with the structure of using a connecting rod mechanism to drive the swing blades 12, the transmission accuracy is higher.

[0046] In some embodiments of the present invention, please refer to Figure 2 and Figure 3 The number of the first guide gears 111 is at least two, and all the first guide gears 111 are arranged at intervals along the length direction Z of the rack 113 .

[0047] Exemplarily, all the second guide gears 112 are respectively provided with at least one first guide gear 111 on both sides of the length direction Z of the rack 113, which can limit the movement of the rack 113 along the first direction X, and the swing of the rack 113 in any direction makes the rack 113 only move along its own length direction Z, thereby guiding the rack 113 and enabling the rack 113 to work more smoothly.

[0048] Exemplarily, the number of the first guide gear 111 is one, and along the length direction Z of the rack 113 , the axis of the first guide gear 111 is located between the axes of the two second guide gears 112 .

[0049] Therefore, the plurality of first guide gears 111 can better guide the rack 113 so that the rack 113 can work smoothly.

[0050] In some embodiments of the present invention, please refer to Figure 2 , along the length direction Z of the rack 113 , the axis of at least one first guide gear 111 is located between the axes of the two second guide gears 112 .

[0051] It should be noted that, in this embodiment, the two second guide gears 112 mentioned may be any two second guide gears 112 among all the second guide gears 112 , that is, the axis of at least one first guide gear 111 is located between the axes of any two second guide gears 112 among all the second guide gears 112 .

[0052] Exemplarily, there are two first guide gears 111, and the two first guide gears 111 are located between the two second guide gears 112 along the length direction Z of the rack 113 to limit the swing of the rack 113 in any direction, so that the rack 113 can only move along its own length direction Z under the drive of the driving mechanism 15. In other examples, along the length direction Z of the rack 113, the axis of one first guide gear 111 is located between the axes of the two second guide gears 112, and the axis of the other first guide gear 111 is located on one side of the second guide gear 112 along the length direction Z of the rack 113.

[0053] Thus, the first guide gear 111 and at least two second guide gears 112 can be arranged in a triangle, that is, on the same plane, a line connecting a point on the axis of the first guide gear 111 and a point on the axis of two of the second guide gears 112 is an acute triangle, so that under the transmission of the first guide gear 111 and the second guide gear 112, the rack 113 can only move along its own length direction Z without swinging, thereby enabling the rack 113 to work stably.

[0054] In some embodiments of the present invention, please refer to Figure 1 , the number of the first guide gear 111 is one, and along the length direction Z of the rack 113, the axis of the first guide gear 111 is located between the axes of the two second guide gears 112, that is, on a plane perpendicular to the axis of the first guide gear 111, the line connecting a point on the axis of the first guide gear 111 and a point on the axis of the second guide gear 112 is an acute triangle, which can form a stable support and limit for the rack 113. Exemplarily, the motor shaft of the motor can be connected to the first guide gear 111 through a key transmission, and the motor shaft of the motor can also be connected to the rack 113 through a gear alone.

[0055] In some embodiments of the present invention, please refer to Figure 2 and Figure 3 In some embodiments of the present invention, the transmission mechanism 11 further includes a first transmission assembly 13 , and the first transmission assembly 13 is transmission-connected to any one of the first guide gear 111 , the rack 113 , and the second guide gear 112 .

[0056] Exemplarily, the first transmission assembly 13 can be a gear set, the output end of the gear set is drivingly connected to any one of the first guide gear 111, the rack 113 and the second output gear, and the drive mechanism 15 includes a motor, and the motor shaft of the motor is drivingly connected to the input end of the gear set.

[0057] Compared with the structure in which the driving mechanism 15 directly drives any one of the first guide gear 111, the rack 113 and the second guide gear 112, the rotation speed of the second guide gear 112 is easily adjusted by setting the first transmission assembly 13 and changing the transmission ratio of the first transmission assembly 13.

[0058] In some embodiments of the present invention, please refer to Figure 2 and Figure 3The first transmission assembly 13 includes a first transmission gear 131 and a second transmission gear 132. The first transmission gear 131 is rotatably disposed on the mounting seat 17 and meshes with the rack 113. The second transmission gear 132 is rotatably disposed on the mounting seat 17 and meshes with the first transmission gear 131, and is drivingly connected to the driving mechanism 15. The driving mechanism 15 is used to drive the second transmission gear 132 to rotate. The number of teeth of the second transmission gear 132 is less than the number of teeth of the first transmission gear 131.

[0059] Exemplarily, the motor shaft of the motor is connected to the second transmission gear 132 through a key transmission, and the rack 113 and the second transmission gear 132 are respectively meshed with the first transmission gear 131. The second transmission gear 132 can be a double gear (a gear with two circles of meshing teeth) or a gear with one circle of meshing teeth.

[0060] Thus, under the drive of the driving mechanism 15, the power is transmitted to the first meshing teeth 1311 of the first transmission gear 131 through the second transmission gear 132, and then transmitted to the rack 113 through the second meshing teeth 1312 of the first transmission gear 131, and finally transmitted to the second guide gear 112 through the rack 113, so as to realize the rotation of the swing blade 12. Compared with the structure in which the driving mechanism 15 directly drives the rack 113 to move through the first transmission gear 131, the output of a larger torque can be realized through the deceleration of the first transmission gear 131 and the second transmission gear 132, so that the swing mechanism can work more reliably.

[0061] In some embodiments of the present invention, please refer to Figure 3 and Figure 4 A first meshing portion and a second meshing portion are formed on the outer circumferential surface of the first transmission gear 131, and the first meshing portion and the second meshing portion are sequentially arranged along the axial direction of the first transmission gear 131. The first meshing portion includes a plurality of first meshing teeth 1311 arranged at intervals along the circumferential direction of the first transmission gear 131, and the second meshing portion includes a plurality of second meshing teeth 1312 arranged at intervals along the circumferential direction of the first transmission gear 131. The first meshing teeth 1311 mesh with the rack 113, and the second meshing teeth 1312 mesh with the second transmission gear 132.

[0062] Compared with the structure in which the first transmission gear 131 has only one circle of first meshing teeth 1311, and the second transmission gear 132 and the rack 113 are both meshed with the first meshing teeth 1311, the number of meshing times of the first meshing teeth 1311 during operation can be reduced, and the life of the first transmission gear 131 can be increased, so as to reduce the probability of damage to the first transmission gear 131, thereby improving the reliability of the operation of the swing device 10.

[0063] In some embodiments of the present invention, please refer to Figure 2The number of the first guide gears 111 is at least two, and all the first guide gears 111 are spaced apart along the length direction of the rack 113. Along the length direction of the rack 113, the first transmission assembly 13 and the first guide gears 111 are spaced apart, and the first transmission assembly 13 is located between two first guide gears 111 among all the first guide gears 111.

[0064] Figure 2 It is shown that there are two first guide gears 111, and the first transmission assembly 13 is located between the two first guide gears 111 along the length direction of the rack 113. With this arrangement, the support position of the rack 113 toward one side of the first transmission assembly 13 can be increased to make the transmission smoother.

[0065] In some embodiments of the present invention, please refer to Figure 2 All the second guide gears 112 have the same number of teeth and the same module. Therefore, all the second guide gears 112 have the same rotation speed under the transmission of the rack 113, so that the plurality of swing blades 12 can swing synchronously.

[0066] In some embodiments of the present invention, please refer to Figure 2 The transmission mechanism 11 also includes a plurality of swing blade driven gears 14 , each of which is rotatably disposed on a mounting seat 17 , and each second guide gear 112 is transmission-connected to each swing blade 12 via the swing blade driven gear 14 .

[0067] Exemplarily, one end of the swing blade 12 is fixedly connected to a rotating shaft, which is connected to the swing blade driven gear 14 via a key. In other examples, one end of the swing blade 12 is provided with a connecting hole, which is connected to the rotating shaft via a key, and the rotating shaft is fixedly connected to the swing blade driven gear 14.

[0068] Therefore, by changing the number of teeth of the swing blade driven gear 14, different torques can be output to achieve multi-stage transmission.

[0069] In some embodiments of the present invention, please refer to Figure 5 The swing device 10 also includes a frame structure 16, which includes a first frame 161 and a second frame 162. The first frame 161 and the second frame 162 are spaced apart along a second direction Y, and the second direction Y is the same as the axial direction of the second guide gear 112. The mounting seat 17 is connected to the first frame 161, and the swing blade 12 is located in the frame structure 16 and is rotatably connected to the second frame 162.

[0070] The frame structure 16 also includes a third frame 163 and a fourth frame 164, the two ends of the third frame 163 are respectively connected to the first frame 161 and the second frame 162, the two ends of the fourth frame 164 are respectively connected to the first frame 161 and the second frame 162, the first frame 161, the second frame 162, the third frame 163 and the fourth frame 164 form the frame structure 16, the connection between the two ends of the third frame 163 and the first frame 161 and the second frame 162, and the connection between the two ends of the fourth frame 164 and the first frame 161 and the second frame 162 include but are not limited to screw connection, one-piece molding by injection molding, riveting or clamping, etc.

[0071] For example, Figure 5 The swing blade 12 is a strip-shaped structure, and both ends of the swing blade 12 are fixedly connected with rotating shafts (not shown in the figure), one of which is rotatably connected to the second frame 162, and the other is transmission-connected to the second guide gear 112. The other rotating shaft and the second guide gear 112 can be made into an integrated structure or a separate structure, and are transmission-connected by a key.

[0072] Optionally, the first frame 161 , the second frame 162 , the third frame 163 and the fourth frame 164 are integrally formed by injection molding.

[0073] Installing the swing blade 12 in the frame can make the swing blade 12 work stably and is also convenient for modular assembly with the housing of the air conditioner.

[0074] In some embodiments of the present invention, the drive mechanism 15 includes a stepper motor or a servo motor. The swing blade 12 is driven by a stepper motor or a servo motor, and the swing blade 12 can be precisely controlled to achieve a predetermined air outlet effect. In other examples, the drive mechanism 15 includes a reduction motor, and the reduction motor can have a self-locking function, so that power can be transmitted from the input end to the output end, and the torque of the output end cannot be reversely transmitted to the input end, such as a motor with a worm gear reducer.
