[0002] When the main unit of an electric clothes drying rack is equipped with an air supply system, a swing blade can be used to control the opening, closing, or reversing of the air supply channel. The swing blade, which spans almost the entire longitudinal direction of the main unit, can enhance the drying function of the electric clothes drying rack. However, this type of swing blade is relatively heavy, and driving the swing blade requires a high-power motor. In addition, it is necessary to avoid twisting the swing blade. Related technical inspiration suggests that synchronous motors can be set on both sides of the swing blade, but this setting increases the difficulty of wiring and also increases the production cost.

[0024] The embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the embodiments described below with reference to the accompanying drawings are exemplary descriptions for explaining the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions of the embodiments of this application.

[0025] Those skilled in the art will understand that, unless specifically stated otherwise, the terms "described" and "the" as used herein may also include plural forms. It should be further understood that the term "comprising" as used in the specification of this application means the presence of the stated features, integers, steps, operations, elements, and / or components, but does not exclude other features, information, data, steps, operations, elements, components, and / or combinations thereof supported by the art. The term "and / or" as used herein refers to at least one of the items defined by the term; for example, "A and / or B" can be implemented as "A," or as "B," or as "A and B."

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0027] refer to Figures 1-6 This application provides a swaying blade device, which includes a swaying blade 1 and an active component 2 and a driven component 3 disposed at both ends of the swaying blade 1. The active component 2 is equipped with a motor 21, which can drive the swaying blade 1 to unfold. The driven component 3 is equipped with a reset component 31, which can drive the swaying blade 1 to reset after the torque of the motor 21 decreases or is removed. The active component 2 and the driven component 3 can make the overall force on both sides of the swaying blade 1 balanced, and the reset component 31 can use the torque output by the motor 21 to store elastic potential energy for driving the swaying blade 1 to reset. One possible implementation is that the swaying blade device is installed at the air outlet of an air supply system to unfold or block the air outlet. The air supply system usually uses a partition to define the air supply channel. The swaying blade device of this application is connected to the partition or base plate of the air supply channel by a fixing plate 4. Another possible implementation is that the swaying blade device is installed in the main unit of the electric clothes drying rack. This could be because the electric clothes drying rack is equipped with an air supply system and uses the swaying blade device of this application as a subordinate part of the air supply system, or the electric clothes drying rack is equipped with a lighting system and uses the swaying blade device of this application as a subordinate part of the lighting system.

[0028] refer to Figure 1In this embodiment, the oscillating blade device is mounted below the top plate 5, which is connected downwards to a fixing plate 4. The fixing plate 4 is located at the two ends of the oscillating blade 1 and is used to connect to the body of the oscillating blade 1 through the active component 2 and the driven component 3, respectively. In other implementations, the fixing plate 4 can be connected to other fixed mounting surfaces. The angle at which the fixing plate 4 connects to other mounting surfaces can be adjusted according to actual conditions without affecting the inventive essence of this embodiment.

[0029] refer to Figures 1-4 The active component 2 includes a motor 21 and a connector 22. The motor 21 has a general wiring port 213 for power supply and control signal transmission. The motor 21 also has a first connecting ear 212 for direct connection to one side of the fixing plate 4. After the motor 21 body is connected to the fixing plate 4, the position of the wiring port 213 can be adjusted as needed. Furthermore, the motor 21 has an output shaft 211 for outputting torque. The output shaft 211 can pass through the fixing plate 4 to reach the other side of the fixing plate 4 for pivotal connection with the connector 22.

[0030] refer to Figure 2 and 4 The connector 22 includes an insertion portion 221 for connection with the oscillating blade 1, a connecting portion 222 extending vertically from the insertion portion 221, and a pivot portion 223 disposed in the connecting portion 222. The pivot portion 223 is provided with a pivot hole 224, the shape of which matches the output shaft 211 of the motor 21 to facilitate rotation driven by the motor 21. This embodiment shows an oblong pivot hole 224, and correspondingly, the output shaft 211 of the motor 21 is also configured as an oblong column. In other embodiments, other non-cylindrical cross-sectional shapes of the pivot hole 224 can be used, such as a polygonal cross-section or an irregular cross-section based on a regular polygon. To meet the torque bearing requirements, the pivot hole 224 can be disposed within the pivot portion 223 protruding from the surface of the connecting portion 222, and the pivot hole 224 extends from the pivot portion 223 to the connecting portion 222.

[0031] Furthermore, mounting cavities 11 are provided on both sides of the oscillating blade 1 for mounting the insertion part 221. In one embodiment, the cross-sectional shape of the mounting cavity 11 is consistent with the cross-sectional shape of the insertion part 221 so that the two can be connected by an interference fit after being nested. The structure of the mounting cavity 11 and the shape formed by its cross-section can be formed by at least two blades stacked together to form an included angle, thereby forming a mounting cavity 11 with a triangular cross-section. The cross-section of the insertion part 221 of the connector 22 is configured as a triangle that matches the mounting cavity 11 so that the insertion part 221 can be inserted into the oscillating blade 1 as a whole. The connecting portion 222 is preferably located at the center of the insertion portion 221 to achieve force balance. For aesthetic purposes, the oscillating blade 1 can be provided with a relief groove 12 to expose the connecting portion 222. Furthermore, if the connecting portion 222 cannot completely fill the relief groove 12, a decorative step 225 can be provided on one side of the connecting portion 222 to fill the relief groove 12, making the decorative step 225 flush with the surface and / or edge of the oscillating blade 1. In another embodiment, the mounting cavity 11 can be implemented by a separate structure connected to the oscillating blade 1. Furthermore, the mounting cavity 11 can be integrally formed with the connecting member 22, and connected to the oscillating blade 1 through the mounting cavity 11.

[0032] refer to Figure 1 , 5 6. The driven component 3 includes an inner rotating shaft 32 and an outer bushing 33 that can be nested with each other with a clearance, and also includes the aforementioned reset member 31 and connector 22. The connector 22 at the driven component 3 has a structure basically the same as that at the driving component 2, adapted to the position of the mounting groove of the oscillating blade 1. The connector 22 at the driven component 3 is mirror-symmetrical to the connector 22 at the driving component 2, that is, the connectors 22 installed on both sides of the oscillating blade 1 are mirror-symmetrical. In one possible embodiment, both the inner rotating shaft 32 and the outer bushing 33 are cylindrical, with the outer diameter of the inner rotating shaft 32 being smaller than the inner diameter of the outer bushing 33 to facilitate a clearance fit. Further, the outer bushing 33 is provided with a second connecting lug 331 for direct connection to one side of the fixing plate 4; the inner rotating shaft 32 can pass through the other side of the fixing plate 4 and be fitted onto the outer bushing 33. Figure 6 As shown, the inner rotating shaft 32 includes an insert section 322 fitted with the outer shaft sleeve 33 and a connector 321 located at the end of the insert section 322. The connector 321 is used to be fitted and fixed with the pivot hole 224 of the connector 22 and can rotate with the rotation of the connector 22. Thus, the cross-sectional shape of the connector 321 is consistent with the cross-sectional shape of the pivot hole 224.

[0033] In this embodiment, the reset component 31 is sleeved outside the inner rotating shaft 32 and connects the fixing plate 4 and the connecting component 22. This causes the connecting component 22 to rotate relative to the fixing plate 4, and the inner rotating shaft 32 rotates with the connecting plate. The inner rotating shaft 32 can also limit the reset component 31 to prevent it from falling off. In this embodiment, the reset component 31 is a torsion spring, and the two ends of the torsion spring are fixed to the fixing plate 4 and the connecting component 22 respectively. Correspondingly, the fixing plate 4 and the connecting component 22 can have pre-set fixing holes for the torsion spring. A torsion spring is a mechanical element that uses an elastic material to store and release torsional energy. In this embodiment, the torsional energy stored in the torsion spring comes from the motor 21 on the active side. The torque of the motor 21 is transmitted to the torsion spring in sequence through the connecting component 22 on the active side, the oscillating blade 1, and the connecting component 22 on the driven side. When the elastic potential energy of the torsion spring is released, it is transmitted in reverse to the connecting component 22 on the master and slave sides, thereby realizing the reset of the oscillating blade 1. When the elastic potential energy of the torsion spring is released, the motor 21 can synchronously reverse to drive the pendulum 1 to reset; the motor 21 can also stop rotating, allowing the output shaft 211 to reset along with the pendulum 1. In another possible embodiment, the reset element 31 can be sleeved inside the outer bushing 33, and its working principle is similar to that described above. Other reset elements 31 that can store the torque of the motor 21 and be released and reused to assist in the reset of the pendulum 1 can be used in this application.

[0034] Considering production costs, the fixed plates 4 on the active and passive sides have the same structure, and the mirror-symmetrical connectors 22 are pre-drilled with torsion spring fixing holes. The hole spacing of the first connecting ear 212 and the second connecting ear 331 is the same.

[0035] In summary, this application provides a swaying blade device, which includes a swaying blade and an active component and a driven component respectively disposed at both ends of the swaying blade. The active component includes a motor that outputs torque, and the driven component includes a reset component for driving the swaying blade to reset. In this swaying blade device, one end of the swaying blade is the active component, and the other end is the driven component. The driven component can utilize the torque stored during the operation of the active component as the driving force to drive the swaying blade to reset, so that the torque at both ends of the swaying blade is properly balanced, avoiding wear and tear on the swaying blade, and also reducing the assembly cost of the swaying blade. It is suitable for swaying blades that are longer and heavier.
