Referring to fig. 1 to 9, the swing driving mechanism includes a loop bar 6, a cam 8 and a driving motor 10 for driving the cam 8 to rotate, wherein the loop bar 6 is sleeved on the sliding bar 5, and a driven gear 7 is arranged at the lower end of the loop bar 6, and the driven gear 7 is fixedly connected to the lower end of the loop bar 6; the cam 8 is arranged on a main shaft of the driving motor 10, an incomplete gear 9 matched with the driven gear 7 is arranged on the cam 8, and the incomplete gear 9 is intermittently meshed with the driven gear 7 in the process of rotating along with the cam 8.
Through the arrangement, when the left wind sweeping blade 2 and the right wind sweeping blade 11 need to be driven to synchronously swing leftwards or rightwards, the driving motor 10 drives the cam 8 to rotate, so that the incomplete gear 9 on the cam 8 is driven to rotate, when the incomplete gear 9 is meshed with the driven gear 7 at the lower end of the sleeve rod 6, the incomplete gear 9 drives the driven gear 7 to rotate, so that the sleeve rod 6 and the slide rod 5 are driven to swing leftwards and rightwards, and when the slide rod 5 swings leftwards and rightwards, the first connecting rod 1 and the second connecting rod 12 are driven to move leftwards and rightwards through the third connecting rod 3 and the fourth connecting rod 4, so that the left wind sweeping blade 2 and the right wind sweeping blade 11 are driven to swing leftwards and right; in this process, the direction of oscillation of the slide bar 5 is determined by the direction of rotation of the main shaft of the drive motor 10, namely: (1) when the driving motor 10 rotates clockwise, the loop bar 6 and the slide bar 5 swing rightwards, so that the first connecting rod 1 and the second connecting rod 12 are driven to move rightwards, the left wind sweeping blade 2 and the right wind sweeping blade 11 are driven to swing leftwards, and left air supply is achieved; (2) when the driving motor 10 rotates anticlockwise, the loop bar 6 and the slide bar 5 swing leftwards, so that the first connecting rod 1 and the second connecting rod 12 are driven to move leftwards, the left wind sweeping blade 2 and the right wind sweeping blade 11 are driven to swing rightwards, and air supply on the right side is achieved.
The cam 8 in this embodiment is an eccentric wheel, the cam 8 and the incomplete gear 9 are of an integral structure, and the loop bar 6 and the driven gear 7 at the lower end thereof are of an integral structure, wherein the outer circle radius of the incomplete gear 9 is larger than the radius of the driven gear 7 at the lower end of the loop bar 6, so as to reserve enough space for the exiting gear to cooperate; the part with gears in the cam 8 controls the left and right wind sweeping blades to deflect in the same direction, and the part without gears controls the left and right wind sweeping blades to deflect in the opposite direction, so that multi-direction wide-angle air supply is realized.
In addition, the rotating shaft 15 of the driven gear 7 is matched with a bottom shell shaft, and a return spring can be added according to actual requirements, so that when the incomplete gear 9 is disengaged from the driven gear 7, the left and right wind sweeping blades can reset, after the left and right wind sweeping blades reset, the driving motor 10 continues to rotate towards the same direction, the sliding rod 5 starts to move in the vertical direction (mainly depending on the vertical downward movement of the sliding rod 5), and therefore the left wind sweeping blade 2 is pushed to deflect leftwards, and the right wind sweeping blade deflects rightwards.
Referring to fig. 1 to 9, the vertical driving mechanism includes a driving groove provided on a cam 8, the driving groove being provided on a back side of the cam 8, the driving groove being composed of a circular arc track 8-1 and an eccentric track 8-2, wherein a center of the circular arc track 8-1 is located on an axis of a main shaft of the driving motor 10; the lower end of the slide rod 5 is provided with a connecting part vertical to the axial direction of the slide rod, and the connecting part horizontally extends into the driving groove and is positioned at the upper end of the driving groove in the cam 8; when the incomplete gear 9 is meshed with the driven gear 7, the connecting part at the lower end of the sliding rod 5 is matched with the circular arc track 8-1 in the driving groove; wherein, the circular arc orbit 8-1 of the driving slot in the said cam 8 locates at the same side with said incomplete gear 9, and the radian of the circular arc orbit 8-1 is equal to radian of said incomplete gear 9; the positions of both ends of the incomplete gear 9 are the same as those of both ends of the circular arc track 8-1.
Through the arrangement, in the process that the driving motor 10 drives the incomplete gear 9 to be meshed with the driven gear 7, because the connecting part at the lower end of the slide rod 5 is positioned in the arc track 8-1 of the driving groove and the circle center of the arc track 8-1 is positioned on the axis of the main shaft of the driving motor 10, the cam 8 cannot drive the slide rod 5 to vertically move, namely when the connecting part at the lower end of the slide rod 5 is positioned in the arc track 8-1 of the driving groove, the slide rod 5 cannot vertically move and only swings left and right under the driving of the loop bar 6; when the incomplete gear 9 is separated from the driven gear 7, the connecting portion at the lower end of the slide rod 5 enters the eccentric track 8-2 in the rotation process of the cam 8, at this time, because the incomplete gear 9 is separated from the driven gear 7, the slide rod 5 does not swing left and right any more, and in the continuous rotation process of the cam 8, the eccentric track gradually approaches the axis of the main shaft of the driving motor 10, so that the slide rod 5 continuously moves towards the axis of the driving motor 10, thereby driving the slide rod 5 to move vertically, further driving the first connecting rod 1 and the second connecting rod 12 to move oppositely or move reversely, and thus the reverse movement of the left wind sweeping blade 2 and the right wind sweeping blade 11 can be realized, that the air supply of the left wind sweeping blade 2 to the left side and the air supply of the right wind sweeping blade 11 to the right side, specifically:
when the incomplete gear 9 and the driven gear 7 are withdrawn from matching, a connecting part at the lower end of the slide rod 5 enters the eccentric track 8-2, so that the slide rod 5 moves downwards and gradually approaches to the axis of the driving motor 10, and the slide rod 5 drives the first connecting rod 1 and the second connecting rod 12 to move in opposite directions, namely the first connecting rod 1 moves rightwards, the second connecting rod 12 moves leftwards, so that the left wind sweeping blade 2 swings leftwards to realize left-side air supply, and the right wind sweeping blade 11 swings rightwards to realize right-side air supply; in the process that the cam 8 continues to rotate, the connecting part at the lower end of the sliding rod 5 gradually moves upwards to drive the sliding rod 5 to move upwards, so that the first connecting rod 1 and the second connecting rod 12 move in opposite directions, the left wind sweeping blade 2 swings rightwards, and the right wind sweeping blade 11 swings leftwards, and therefore resetting is achieved. After the left wind sweeping blade 2 and the right wind sweeping blade 11 are reset, the connecting part at the lower end of the sliding rod 5 enters the arc track 8-1, so that the left wind sweeping blade 2 and the right wind sweeping blade 11 swing in the same direction.
In addition, an arc track 8-1 of a driving groove in the cam 8 and the incomplete gear 9 are arranged on the same side, and the radian of the arc track 8-1 is equal to that of the incomplete gear 9; the positions of the two ends of the incomplete gear 9 and the two ends of the arc track 8-1 are the same, so that when the incomplete gear 9 is meshed with the driven gear 7, the connecting part at the lower end of the sliding rod 5 enters the arc track 8-1, the sliding rod 5 can be ensured to swing left and right and move vertically to be separated, interference does not occur, the left wind sweeping blade 2 and the right wind sweeping blade 11 can swing in the same direction or in the opposite direction, and the two swing modes are selected and do not interfere with each other.
In this embodiment, the track size of the driving slot in the cam 8 is adjusted according to actual requirements, and the included angle between the third connecting rod 3 and the fourth connecting rod 4 is adjusted, so as to control the amplitude of the up-and-down movement of the slide rod 5, thereby ensuring that the included angle between the third connecting rod 3 and the fourth connecting rod 4 does not exceed 180 ° in the process of the up-and-down movement of the slide rod 5 to drive the third connecting rod 3 and the fourth connecting rod 4 to move, the driving slot in the cam 8 is divided into an arc track 8-1 and an eccentric track 8-2, the angle of the arc track 8-1 with the main shaft of the driving motor 10 as the axis is consistent with the angle of the incomplete gear 9, that is, when the incomplete gear 9 and the driven gear 7 are withdrawn from matching, the slide rod 5 can start to gradually approach the axis of the driving motor 10 under the driving of the eccentric track 8-2, and after reaching the, gradually gets away from the axis of the driving motor 10 and enters the circular arc track 8-1 again.
Referring to fig. 1 to 9, a first limit block 14 is provided at a position where the first connecting rod 1 is hinged to the third connecting rod 3, and the first limit block 14 is used for limiting a swing angle of the third connecting rod 3; a second limit block 13 is arranged at a position where the second connecting rod 12 is hinged to the fourth connecting rod 4, and the second limit block 13 is used for limiting the swing angle of the fourth connecting rod 4; the first limiting block 14, the first connecting rod 1, the second limiting block 13 and the second connecting rod 12 are of an integral structure, the inclination angles of the first limiting block 14 and the second limiting block 13 are determined according to the distance between the left wind sweeping blade 2 and the right wind sweeping blade 11 and the maximum deflection angle of the blades, and the lengths of the first limiting block 14 and the second limiting block 13 need to ensure that the third connecting rod 3 and the fourth connecting rod 4 do not deflect when the sliding rod 5 swings left and right.
When the incomplete gear 9 is matched with the driven gear 7, the main shaft of the driving motor 10 rotates to drive the slide rod 5 to swing left and right, and because the hinged part of the first connecting rod 1 and the third connecting rod 3 is provided with the first limiting block 14, and the hinged part of the second connecting rod 12 and the fourth connecting rod 4 is provided with the second limiting block 13, when the slide rod 5 swings left, the first limiting block 14 at the first connecting rod 1 is pushed to push the first connecting rod 1 to move left, and the fourth connecting rod 4 drags the second connecting rod 12 to move left; when the sliding rod 5 swings rightwards, the second limiting block 13 at the second connecting rod 12 is pushed by thrust to push the second connecting rod 12 to move rightwards; the movement of the first connecting rod 1 and the second connecting rod 12 drives the left wind sweeping blade 2 and the right wind sweeping blade 11 to deflect respectively, so that the left and right wind direction adjustment is realized. When the incomplete gear 9 is disengaged from the driven gear 7, the first link 1 and the second link 12 are automatically restored to the initial positions by the biasing force of the left and right wind-sweeping blades 2 and 11 (here, it is possible to provide a return spring which pulls the sleeve lever 6 and the slide lever 5 back to the initial positions, i.e., the forward positions, when the incomplete gear 9 is separated from the driven gear 7). Subsequently, the driving motor 10 drives the cam 8 to continue rotating, at this time, the loop bar 6 cannot swing left and right, and the cam 8 starts to drive the slide bar 5 to move up and down, wherein when the slide bar 5 moves down, the third connecting rod 3 and the fourth connecting rod 4 push the first connecting rod 1 and the second connecting rod 12 to move left and right respectively, so that the left wind sweeping blade 2 and the right wind sweeping blade 11 deflect, the left wind sweeping blade 2 sweeps wind to the left, and the right wind sweeping blade sweeps wind to the right, thereby realizing wide-angle air supply.
Referring to fig. 1-9, the multi-directional wide-angle air guiding device of the present invention has the following two operation modes:
(1) left and right blowing modes
If the multi-directional wide-angle air guide device is in the initial position, the incomplete gear 9 is meshed with the driven gear 7, when air needs to be supplied leftwards or rightwards directionally, the driving motor 10 rotates to drive the loop bar 6 to swing, and further the left and right air sweeping blades are driven to deflect, so that a left or right air supply mode is realized, when the air needs to be supplied leftwards or rightwards, the driving motor 10 rotates for a certain angle according to the original direction, the gear meshing is withdrawn, at the moment, the left and right air sweeping blades automatically recover to the original positions due to elastic deformation stress, and then the driving motor 10 rotates reversely, so that the switching can be performed.
(2) And a wide-angle air supply mode: if the multidirectional wide-angle air guide device is at the initial position, the driving motor 10 rotates in the direction, the left and right wind sweeping blades deflect, when the incomplete gear 9 is disengaged, the left and right wind sweeping blades automatically recover to the original positions, the cam 8 drags the sliding rod 5 to move downwards, the first connecting rod 1 and the second connecting rod 12 move in opposite directions, and the left and right wind sweeping blades deflect in opposite directions, so that wide-angle wind sweeping is realized; when the multi-directional wide-angle air guide device is switched to wide-angle air supply under the condition of supplying air leftwards or rightwards, the driving motor 10 continuously rotates towards the same direction, and after the incomplete gear 9 is withdrawn from meshing, the cam 8 drags the sliding rod 5 to move, so that wide-angle air sweeping is realized.
Example 2
The difference between this embodiment and embodiment 1 is that the left wind sweeping blade 2 and the right wind sweeping blade 11 may also be driven by two sets of motors, respectively, so as to realize the respective control of the left wind sweeping blade 2 and the right wind sweeping blade 11, and also realize the wide-angle air supply.
Example 3
The air conditioner comprises the multidirectional wide-angle air guide device.
The present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents and are included in the scope of the present invention.
