[0040] The swing drive assembly is mainly described in conjunction with a clothes drying machine in the specification, but it can be understood that the swing drive assembly according to the embodiment of the utility model can also be used for other air supply equipment (for example, a bathroom heater, etc.).

[0041] According to one aspect of the utility model, a swing drive assembly for air supply equipment is provided.

[0042] Figure 1 1 shows a plurality of views of a swing drive assembly 100 for an air supply device according to some embodiments of the present invention. Specifically, Figure 1 A left side view and a front view of the swing drive assembly 100 are shown at the top, respectively, and an exploded view of the swing drive assembly 100 is shown at the bottom.

[0043] The swing drive assembly 100 may include a swing motor 110, a swing arm 130, and a swing bracket 150. The swing motor 110 may include an output shaft 115 for rotating to output torque. The swing arm 130 may include opposite ends 132 and 134. The end 132 may be connected to the output shaft 115 of the swing motor 110 to be driven by the output shaft 115.

[0044] The swing bracket 150 may include a rotating end 152 and a slot 154 extending along a track. The slot 154 may define the end 134 of the swing arm 130 so that the swing bracket 150 swings around the rotating end 152 under the drive of the swing arm 130 (for example, in Figure 1 The swing bracket 150 may be connected to a swing housing (not shown) used in conjunction therewith, so that the swing housing can swing to both sides relative to the swing return position of the housing.

[0045] In use, the output shaft 115 of the swing motor 110 drives the end 132 of the swing arm 130, so that the swing arm 130 rotates at the end 132 relative to the axis defined by the output shaft 115. The end 134 of the swing arm 130 is constrained in the slot 154 of the swing bracket 150. As the swing arm 130 rotates around the end 132, its end 134 moves along the slot 154, thereby driving the swing bracket 150 to swing around its rotating end 152 (for example, in Figure 1 In the upper view shown in the figure, it swings to the left or right), thereby driving the cooperating swing housing to swing, so as to realize the swinging air guiding of the clothes drying machine, wherein the swinging of the swing bracket 150 can drive the cooperating swing housing to swing to both sides respectively relative to the swinging return position of the swing housing. The various elements of the swing bracket 150 (for example, the position, direction, shape, etc. of the groove 154, the position where the swing bracket 150 is connected to the end 134 of the swing arm 130, etc.) can be set so that the end 134 of the swing arm 130 can reciprocate along the trajectory of the groove 154, and when the end of the swing arm 130 reverses back along the trajectory of the groove 154, the cooperating swing housing can reverse by swinging back to the normal position. The driving and driven process of the swing bracket 150 will be described in conjunction with the following. Figure 2 Further description.

[0046] According to the embodiment of the utility model, the swing drive assembly 100 restricts the end 134 of the swing arm 130 driving it within the groove 155 for reciprocating motion through the swing bracket 150, and drives the swing housing to swing to both sides of the swing return position through the swing return position reversal of the swing housing, and the transmission torque of the swing bracket 150 is large, so that the swing housing can be driven only on one side of the swing housing.

[0047] Figure 2 A driving schematic diagram of a swing drive assembly for an air supply device according to some embodiments of the utility model is shown.

[0048] Specifically, Figure 2 Shown in Figure 1 The swing arm 130 of the swing drive assembly in the swing drive assembly drives the swing bracket 150 to swing during the process of rotating around the end 132 driven by the swing motor 110. For the sake of clarity, Figure 2 The swing motor is not shown in the figure, and the swing arm is represented by a long strip shape, wherein the end 132 thereof is represented by a black circle, and the end 134 thereof is represented by a white circle. Figure 2 In each schematic diagram, a schematic diagram showing the rotation angle of the swing arm 130 from the previous position to the current position is also shown.

[0049] At (a), the swing bracket 150 is in the swing return position (ie, not swinging). The end 134 of the swing arm 130 is at the starting point of the trajectory defined by the slot 154 of the swing bracket 150 .

[0050] As the output shaft of the swing motor rotates counterclockwise (from Figure 2 The swing drive assembly moves to the state shown in (b). The end 134 of the swing arm 130 moves downward along the track from the starting point of the track defined by the slot 154, and accordingly drives the swing bracket 150 to swing to the left.

[0051] The output shaft of the swing motor continues to rotate counterclockwise, and the swing drive assembly moves to the state shown at (c). The end 134 of the swing arm 130 moves downward along the track from the middle position of the track defined by the slot 154 to the end point of the track, correspondingly driving the swing bracket 150 to swing rightward and return to the center.

[0052] The output shaft of the swing motor continues to rotate counterclockwise, and the swing drive assembly moves to the state shown at (d). The end 134 of the swing arm 130 moves upward along the track from the end point of the track defined by the slot 154, and accordingly drives the swing bracket 150 to swing rightward.

[0053] The output shaft of the swing motor continues to rotate counterclockwise, and the swing drive assembly moves to the state shown at (e). The end 134 of the swing arm 130 moves upward along the track from the middle position of the track defined by the slot 154 to the starting point of the track, and accordingly drives the swing bracket 150 to swing leftward and return to the center.

[0054] After that, the output shaft of the swing motor can continue to rotate counterclockwise to repeat Figure 2 The states (a) to (e) in FIG.

[0055] In some embodiments, when the swing bracket 150 is in the swing return position (eg, Figure 2 As shown in (a), (c), and (e) in the figure, the projections of the end 132, the end 134 of the swing arm 130 and the rotating end 152 of the swing bracket 150 on the plane defined by the swing direction of the swing bracket 150 are collinear.

[0056] In some embodiments, when the swing bracket 150 is in the swing return position (eg, Figure 2 As shown in (a), (c), and (e) in the figure, the projections of the end 132, the end 134 of the swing arm 130, and the midpoint of the slot 154 of the swing bracket 150 in the track direction on the plane defined by the swing direction of the swing bracket 150 are collinear.

[0057] In some embodiments, when the swing bracket 150 is in the swing return position (eg, Figure 2As shown in (a), (c), and (e) in the figure, the end 132 and the end 134 of the swing arm 130, the midpoint of the slot 154 of the swing bracket 150 in the track direction, and the projection of the rotating end 152 on the plane defined by the swing direction of the swing bracket 150 are collinear.

[0058] By arranging the swing bracket 150 so that the two end portions 132, 134 of the swing arm 130 are collinear with respect to the midpoint of the groove 154 of the swing bracket 150 in the track direction and / or the projection of the rotating end 152 on the plane defined in the swing direction when in the swing return position, the sliding or movement of the swing bracket 150 in the swing return position can be reduced and its stability can be increased.

[0059] The following will combine Figure 3 The above-mentioned collinear relationship is further described and illustrated.

[0060] In some embodiments, the end 132 of the swing arm 130 and the rotating end 152 of the swing bracket 150 define a swing return position within a plane defined by the swing direction. Figure 2 As shown by the dotted lines in (a)-(e), during the swinging process of the swing bracket 150, the projections of the end 132 of the swing arm 130 and the rotating end 152 of the swing bracket 150 in the plane defined by the swinging direction always define a fixed straight line in the vertical direction (because the output shaft of the motor driving the end 132 is fixed, and the position of the rotating end 152 of the swing bracket 150 is unchanged), which can always indicate the swing return position of the swing bracket 150 (that is, when the center line of the swing bracket 150 coincides with the above-mentioned dotted line, the swing return position is reached). By setting the swing return position of the swing bracket 150 to correspond to the straight line defined by the end 132 of the swing arm 130 and the rotating end 152 of the swing bracket 150, which are relatively fixed in position, the stability of the swinging of the swing bracket 150 can be enhanced while increasing the torque transmission efficiency.

[0061] The following will combine Figure 3 The determination of the swing home position is further described and illustrated.

[0062] In some embodiments, the swing bracket 150 is configured so that the swing arm 130 is located in one direction around its end 132 (eg, Figure 2 During the rotation (always counterclockwise in the figure), the swing bracket 150 can rotate in two opposite directions (for example, Figure 2Thus, when the output shaft of the swing motor continuously rotates in one direction, the swing bracket 150 can be cyclically swung in two opposite directions. By setting the swing bracket 150 to be able to swing in two opposite directions without reversing the rotation of the swing arm 130, the swing in two opposite directions can be achieved without adjusting the rotation direction of the output shaft of the swing motor, thereby avoiding vibration and instability caused by the output shaft of the motor changing its rotation direction.

[0063] In some embodiments, the trajectory of the slot 155 of the swing bracket 150 can be a straight line (e.g., Figure 2 ) or curves shown in .

[0064] In some embodiments, the swing bracket 150 is configured to be in the swing return position when the end 134 of the swing arm 130 is at the start or end of the track. Thus, the return of the swing bracket 150 can be accurately controlled by the end point of the track of the slot 155 of the swing bracket 150, and the stability of the swing bracket 150 when it is in the swing return position is enhanced.

[0065] Figure 3 A schematic diagram of the assembly of a swing drive assembly for an air supply device and a swing housing 310 used in conjunction therewith according to some embodiments of the utility model is shown.

[0066] Figure 3 An exploded view of the swing motor 110 , the swing arm 130 , the swing bracket 150 and the swing housing 310 used in conjunction therewith is shown at the top, wherein the assembly relationship is shown by dotted lines, and an assembled view thereof is shown at the bottom.

[0067] Figure 3 1 and 2 more clearly show that the output shaft 115 of the swing motor 110 is connected to the end 132 of the swing arm 130. The end 134 of the swing arm 130 rotates relative to the end 132 as the swing arm 130 rotates around the end 132. The position of the rotating end 152 of the swing bracket 150 is fixed, and the end 134 of the swing arm 130 moves in the slot 154 of the swing bracket 150, thereby driving the swing bracket 150 to swing relative to the rotating end 152. Further, the swing bracket 150 can be connected to the swing housing 310 (as shown by two parallel dotted lines), thereby driving the swing housing 310 to swing together with the swing bracket 150.

[0068] The swing housing 310 may include an air guide portion 312. As the swing housing 310 swings, the air guide portion 312 may move to both sides to guide the blown air to both sides.

[0069] Figure 3Also shown is the swing return position 320 of the swing bracket 150 and the swing return position 314 of the swing housing 310. The swing return position 320 and the swing return position 314 may be consistent. The swing return position 320 may be determined by a line connecting the projections of the end 132 of the swing arm 130 and the rotating end 152 of the swing bracket 150 on a plane defined by the swing direction.

[0070] When in the swing return position, the ends 132 and 134 of the swing arm 130 may be collinear relative to the rotating end 152 and / or the midpoint of the slot 154 of the swing bracket 150 (eg, may be in the swing return position 320).

[0071] Figure 4 Further details of the swing drive assembly 100 for an air supply device according to some embodiments of the present invention are shown.

[0072] In some embodiments, the swing drive assembly 100 may further include a sensing component 410. The sensing component 410 may be disposed on the swing bracket 150. As an example, the sensing component 410 may include a magnetic sensing component. Accordingly, the air supply device may include a position sensor 430 used in conjunction with the sensing component 410, and the position sensor may be fixed relative to the air supply device. As the swing bracket 150 swings, the position of the sensing component 410 relative to the position sensor 430 (e.g., the distance between them) changes, thereby sensing the swing position of the swing bracket 150.

[0073] In some embodiments, the sensing component 410 may be disposed at an end of the swing bracket 150 away from the rotating end 152 and centered in the width direction of the swing limit of the swing bracket. Thus, when the swing bracket 150 is in the swing return position, the distance between the sensing component 410 and the position sensor 430 is the shortest.

[0074] In some embodiments, the swing drive assembly 100 may include a motor bracket 450 that is used to fix the swing motor 110 and is fixed relative to the air supply device.

[0075] Figure 5 A swing drive assembly 500 for an air supply device according to some embodiments of the present invention is shown.

[0076] In some embodiments, the swing drive assembly 500 may include a swing motor 510, a swing arm 520, a swing bracket 530, a swing bracket 540 and a synchronous connector 550. The swing motor 510, the swing arm 520 and the swing bracket and their matching methods can be respectively combined with the above Figure 1-Figure 4The swing motor 110, swing arm 130, and swing bracket 150 described above are similar. In some embodiments, the swing drive assembly 500 may also include a motor bracket 560, which may be combined with the above Figure 4 The motor mount 450 described is similar.

[0077] The synchronous connecting member 550 can be connected (for example, at both ends thereof) to the swing bracket 530 and the swing bracket 540. Thus, the swing bracket 540 can be synchronously swung by transmitting the swing of the swing bracket 530, without providing a separate swing motor for the swing bracket 540, and the swing of the swing bracket 530 and the swing bracket 540 has good synchronization.

[0078] Figure 5 The lower view in FIG. 5 shows further details of the wobble drive assembly 500 .

[0079] In some embodiments, the swing drive assembly 500 may further include a support frame 570. The support frame 570 may be fixed relative to the air supply device and used to support the motor bracket 560.

[0080] In some embodiments, the air supply device may be a clothes drying machine. In some embodiments, the support frame 570 may include a support platform 572. The support platform 572 may be used to separate the synchronous connector 550 from a guide wheel drive assembly (not shown) of the clothes drying machine. Figure 5 As shown in , the synchronous connector 550 can be arranged above the support platform 572, and the guide wheel driving assembly can be arranged below the support platform 572. Thus, the movement of the synchronous connector 550 caused by the swing of the swing bracket 530 and the movement of the guide wheel driving assembly are separated from each other and are not affected, thereby increasing the safety of the clothes drying machine.

[0081] Alternatively or additionally, in some embodiments, the support frame may include a side plate 574. The side plate 574 may be used to separate the guide wheel drive assembly of the clothes drying machine (for example, it may be located below the support platform 572) from the swing housing used in conjunction therewith (not shown, for example, it may be on the left and / or right side of the support frame 570). As a result, the swing of the swing housing of the clothes drying machine is separated from the movement of the guide rope drive assembly and is not affected, thereby increasing the safety of the clothes drying machine.

[0082] In some embodiments, the synchronous connector 550 and the swing housing that can be located on the right side are located on opposite sides of the swing bracket 530. The synchronous connector 550 and the swing housing that can be located on the left side are located on opposite sides of the swing bracket 540. Thus, the synchronous connector 550 and the swing housing are separated from each other and are not affected, thereby increasing the safety of the clothes drying machine.

[0083] Figure 6 Further details of the swing drive assembly for air supply equipment according to some embodiments of the present invention are shown.

[0084] Figure 3 An exploded view of the synchronous connector 550, the swing bracket 530 and the support bracket 570 is shown at the top, wherein the assembly relationship is shown by dotted lines, and an assembled view thereof is shown at the bottom.

[0085] The synchronous connecting member 550 may include a connecting portion 552 and a connecting portion 554 at opposite ends in the extending direction of the length thereof. The connecting portion 552 may be connected to the swing bracket 530 to synchronize with the movement of the swing bracket 530. Similarly, the connecting portion 554 may be connected to another swing bracket (not shown) to synchronize the swing of the swing bracket 530 with the swing of the other swing bracket.

[0086] As an example, the connection portion 552 may include a notch, and the swing bracket 530 (e.g., at its rotation end) may include a corresponding protruding structure to achieve the connection between the two. Alternatively, the connection portion 552 may include a protruding structure, and the swing bracket 530 (e.g., at its rotation end) may include a corresponding notch.

[0087] The support bracket 570 may include a support portion 576 and a support portion 578 at opposite ends in the extension direction of the length thereof. The support portion 578 may at least partially support the swing bracket 530 on a side opposite to the connection portion 552 of the synchronous connector 550. Thus, the swing bracket 530 may be disposed between the connection portion 552 and the support portion 576. Similarly, another swing bracket (not shown) may be disposed between the connection portion 557 and the support portion 578.

[0088] By arranging a swing bracket (for example, a swing bracket 530 or another connecting part) between the connecting part (for example, connecting parts 552, 554) of the synchronous connecting member 550 and the corresponding supporting part (for example, supporting parts 576, 578) of the support frame 570, the synchronization between the two swing brackets can be reliably achieved with a simple structure, and the two swing brackets can be connected to the support frame (for example, support frame 570).

[0089] According to another aspect of the utility model, an air supply device is provided.

[0090] Figure 7 An air supply device 700 according to some embodiments of the present invention is shown. In some embodiments, the air supply device 700 may be a clothes drying machine.

[0091] The air supply device 700 may include a housing 710 and a swing drive assembly 720, a wind wheel assembly 730, and a wind wheel assembly 740 in the housing 710. The swing drive assembly 720 may be combined with the above Figure 1-Figure 6 The swing drive assembly 100 described herein or in combination with Figure 5 The wobble drive assembly 500 described is similar.

[0092] The wind wheel assembly 730 may include a swing housing 732. The swing housing 732 may be connected to the swing drive assembly 720.
