Referring to fig. 1, 2 and 3, an air duct structure 1000 according to an embodiment of the present application includes an air duct 100, an opening and closing assembly 200 and a locking assembly 300, wherein the air duct 100 has a ventilation port S for ventilation. The opening and closing assembly 200 includes a driving member 210 and an opening and closing member 220, wherein the opening and closing member 220 is configured to be rotatably disposed relative to the air duct 100 around a set first axial direction X1, and the driving member 210 is in transmission connection with the opening and closing member 220 and is capable of driving the opening and closing member 220 to move toward or away from a target position W for closing the flow port S. The locking assembly 300 is provided to the air duct 100 for providing a locking force to the shutter 220 to prevent it from moving away from the target position W.

The ventilation port S is used for ventilation air, and may be an inlet of the air duct 100 or an outlet of the air duct 100. The plurality of the opening and closing assemblies 200 may be configured correspondingly when the plurality of the opening and closing assemblies S are configured, and the opening and closing member 220 of each opening and closing assembly 200 is correspondingly configured to open and close one opening and closing assembly S, or the plurality of opening and closing members 220 included in the same opening and closing assembly 200 are driven by the same driving member 210 to open and close different opening and closing assemblies S. The number of the flow ports S and the number of the opening and closing members 220, and the specific arrangement manner are not particularly limited in the embodiment of the present application, so long as the opening and closing members 220 can open and close at least one flow port S. Of course, when the air duct 100 includes a plurality of flow ports S, only one of the flow ports S may be opened and closed by the opening and closing member 220, and other flow states may not be controlled by the opening and closing member 220, which is specific to the practical application.

The air duct 100 may have a shell-like structure, and when the air duct structure 1000 is applied to the air supply device, the air duct 100 may be independently disposed with respect to other structures of the air supply device, or may be integrally formed with other structures of the air supply device, and the specific application of the air duct structure 1000 to the air supply device is not specifically limited,

The driving member 210 can provide a rotational driving force to the opening and closing member 220 to drive the opening and closing member 220 to rotate around the set first axial direction X1, and the driving member 210 may include a power source such as a rotating electric machine 211 and a motor, and a transmission structure (such as a gear, a coupling, and a decelerator) connecting the power source and the opening and closing member 220, so long as it can drive the opening and closing member 220 to rotate, and the specific configuration of the driving member 210 is not particularly limited in the embodiment of the present application.

The opening and closing member 220 may be an opening and closing plate, which has a shape substantially similar to the flow opening S opened and closed by itself, and is capable of opening and closing the corresponding flow opening S. The specific construction of the shutter 220 is not limited in the embodiment of the present application as long as the opening and closing of the flow port S can be achieved. It should be noted that, the opening and closing member 220 closes the ventilation opening S includes that the opening and closing member 220 covers the ventilation opening S, and also includes that the opening and closing member 220 is located on a path of the air flowing to the ventilation opening S, and at this time, the opening and closing member 220 can block the air so that the air cannot flow to the ventilation opening S, and the opening and closing member 220 is located on a path of the air duct 100 where the air flows to the ventilation opening S although the opening and closing member 220 does not cover the ventilation opening S. That is, the target position W of the shutter 220 may be a position covering the corresponding flow port S, or may be a position in the duct 100 that blocks the air flow to the corresponding flow port S.

The opening and closing member 220 may be disposed inside the air duct 100 or may be disposed outside the air duct 100. When the opening and closing member 220 is disposed outside the air duct 100, the target position W of the opening and closing member 220 may be a position where the opening and closing member 220 covers the corresponding flow port S. The arrangement of the opening and closing member 220 on the air duct 100 is not limited in the embodiment of the present application, as long as the opening and closing of the corresponding flow port S by the opening and closing member 220 can be achieved.

The locking assembly 300 is disposed on the air duct 100 and is used for providing a blocking force for blocking the opening and closing member 220 from leaving the target position W to the opening and closing member 220, that is, when the driving member 210 drives the opening and closing member 220 to leave the target position W, the blocking force provided by the locking assembly 300 needs to be overcome, so that the difficulty of the opening and closing member 220 leaving the target position W can be increased, and the position stability of the opening and closing member 220 at the target position W can be enhanced.

The blocking force provided by the locking assembly 300 may be an adsorption force, an elastic force, a friction force, or the like. For example, when the blocking force provided by the locking assembly 300 is an adsorption force, a magnetic adsorption member (such as a magnet) may be disposed on the air duct 100 corresponding to the target position W of the opening and closing member 220, and when the opening and closing member 220 is located at the target position W, the magnetic adsorption member may adsorb the opening and closing member 220, so as to enhance the stability of the opening and closing member 220 at the target position W. As another example, when the blocking force provided by the locking assembly 300 is an elastic force, a torsion spring may be disposed on the rotation shaft of the shutter 220, the torsion spring generates a minimum torque to the rotation shaft of the shutter 220 when the shutter 220 is at the target position W, and the torsion spring generates a torque to overcome the shutter 220 to leave the target position W. As another example, when the blocking force provided by the locking assembly 300 is a friction force, a clamping structure may be disposed at a position of the air duct 100 corresponding to the target position W, and when the opening and closing member 220 is located at the target position W, the clamping structure is located in a clamping range of the clamping structure, and when the opening and closing member 220 needs to be separated from the target position W, the friction force generated by the clamping structure on the opening and closing member 220 needs to be overcome. The specific embodiment of the locking assembly 300 is not limited herein.

In the above air duct structure 1000, when the flow port S of the air duct 100 needs to be closed, the driving member 210 drives the opening and closing member 220 to rotate to the target position W for closing the flow port S, and meanwhile, under the obstruction of the locking assembly 300, the opening and closing member 220 is not easy to leave the target position W under the driving of the driving member 210, and the opening and closing member 220 can maintain a relatively stable position state at the target position W. When the circulation port S needs to be opened, the driving force generated by the driving member 210 overcomes the blocking force of the locking assembly 300 to drive the opening and closing member 220 to rotate away from the target position W, so as to realize the opening of the circulation port S.

Compared with the prior art, the opening and closing piece 220 is positioned at the target position W for closing the circulation port S by the self-locking force of the driving piece 210, the position stability of the opening and closing piece 220 can be enhanced under the blocking force provided by the locking assembly 300, the positioning of the opening and closing piece 220 is more reliable, the opening and closing piece 220 is not easy to loose at the target position W, the sealing effect on the circulation port S is good, and the air leakage problem of the air duct 100 is not easy to occur.

In some embodiments, referring to fig. 1, the air duct 100 has at least two flow ports S, the opening and closing member 220 is configured to be capable of switching between at least two target positions W during rotation, and when the opening and closing member 220 sequentially approaches each target position W, the flow ports S corresponding to the target positions W are respectively closed. That is, the same opening and closing member 220 can be used for opening and closing the plurality of flow openings S, so that the utilization efficiency of the opening and closing member 220 can be provided, and the structure of the air duct structure 1000 can be simplified.

In the embodiment of the present application, the actual application situation that the plurality of opening and closing members 220 respectively close the plurality of flow ports S at the plurality of target positions W during the rotation process is not specifically limited. As an example, the duct 100 has a plurality of air outlets located in an annular plane formed by the rotational locus of the shutter 220, and when the shutter 220 is stopped at each target position W, one end of the shutter 220 in the radial direction can close the corresponding air outlet. As another example, the duct 100 has a plurality of air outlets located in a plane perpendicular to the rotation axis of the shutter 220, and when the shutter 220 is stopped at each target position W, one end of the shutter 220 in the axial direction can close the corresponding air outlet.

In some embodiments, the locking assembly 300 is elastically coupled to the duct 100 and the shutter 220, for providing an elastic force to the shutter 220 that impedes its movement away from the target position W.

The locking assembly 300 may be elastically coupled to the duct 100 and the shutter 220 in such a manner that the locking assembly 300 includes the torsion spring as described above, connects the duct 100 and the shutter 220 using the torsion spring, and blocks the shutter 220 from leaving the target position W by the torsion spring. Of course, the specific construction of the locking assembly 300 may also take the form of the embodiments described below.

At this time, the locking assembly 300 is reliable in structure and easy to implement by providing an elastic force to prevent the shutter 220 from moving away from the target position W.

In a specific embodiment, referring to fig. 2 and 3, the opening and closing member 220 has a switching portion 221, the switching portion 221 is rotatably disposed around the first axial direction X1 relative to the air duct 100, and the locking assembly 300 is elastically connected to the switching portion 221 and the air duct 100, so as to block the switching portion 221 from the elastic force of the opening and closing member 220 from leaving the target position W.

The opening and closing member 220 is rotatably connected with the air duct 100 through the switching portion 221. The adaptor 221 may be an adaptor shaft, an adaptor hole, etc., and is not limited in specific form. The locking assembly 300 elastically connects the switching part 221 and the duct 100, and prevents the shutter 220 from moving away from the target position W by directly applying a blocking force to the switching part 221.

When the adapting part 221 is an adapting shaft, the locking assembly 300 is provided with a sleeve joint hole which is in anti-rotation connection with the adapting shaft, and when the adapting part 221 is an adapting hole, the locking assembly 300 is provided with a connecting shaft which extends into the adapting hole and is fixedly connected with the adapting hole.

At this time, the locking assembly 300 applies a blocking force to the switching portion 221 of the opening and closing member 220, and the rotation of the opening and closing member 220 is blocked by blocking the rotation of the switching portion 221, so that the acting manner is more direct, and the air duct structure 1000 is simplified.

Of course, in other embodiments, the locking assembly 300 may also be applied to other portions of the shutter 220 to limit the movement of the shutter 220, which is not limited in the embodiments of the present application.

In particular, in the embodiment, the locking assembly 300 includes a first rotating member 310, a second rotating member 320, and an elastic member 330, and one end of the first rotating member 310 is connected to the adapting portion 221 and rotates along with the adapting portion 221. One end of the second rotating member 320 is rotatably disposed on the air duct 100 around a second axis X2 parallel to the first axis X1. The elastic member 330 is connected to and elastically deforms following the position change of the other end of the first rotating member 310 and the other end of the second rotating member 320.

The first rotating member 310 and the second rotating member 320 may be rod-shaped members, block-shaped members, or the like, and one end (defined as a first coupling end) of the first rotating member 310 is fixedly connected to the coupling portion 221, which may include the above-mentioned socket hole or coupling shaft, and the coupling portion 221 drives the first rotating member 310 to rotate when rotating. One end (defined as a second transition end) of the second rotary member 320 is rotatably connected to the air duct 100 and rotates around the second axis X2. The first axial direction X1 is parallel to and non-coincident with the second axial direction X2. The elastic member 330 connects the other end (defined as a first following end) of the first rotating member 310 and the other end (defined as a second following end) of the second rotating member 320, and as for the connection manner, it is possible but not limited to, that both deformed ends of the elastic member 330 are fixedly connected to the first following end and the second following end.

The elastic member 330 may be a combination of one or more of a spring, an elastic rubber member, an elastic silicone member, and the like. Preferably, the elastic member 330 is a spring, which has a large deformability and a large recovery capability, and is more reliable in structure.

When the switching part 221 rotates, the first switching end of the first rotating member 310 rotates around the first axial direction X1, the first following end thereof rotates around the first axial direction X1, and drives the second following end to move through the elastic member 330, and the second following end is driven to rotate when moving, and meanwhile, the second following end can only rotate around the second axial direction X2 under the limitation of the second switching end. That is, the first follower moves circumferentially around the first axis X1 and the second follower moves circumferentially around the second axis X2, and the expansion and contraction length of the elastic member 330 connecting the first and second follower changes during rotation due to misalignment of the centers of rotation. The elastic member 330 can act on the first following end to limit the movement thereof when undergoing the telescopic deformation, so as to block the rotation of the first transferring end, thereby achieving the purpose of preventing the opening and closing member 220 from rotating to open the target position W.

When the shutter 220 is in the target position W, the elastic member 330 may be in a pre-compressed length, a pre-stretched length, or a free initial length, with a minimum distance between the first trailing end and the second trailing end. In some cases, when the shutter 220 is about to move away from the target position W, the distance between the first follower end and the second follower end tends to increase, and the elastic member 330 may be a tension spring (corresponding to the pre-stretched length or the free initial length) that resists the increase in distance between the first follower end and the second follower end and resists the movement of the shutter 220 away from the target position W. In some cases, when the shutter 220 is about to move away from the target position W, the distance between the first follower end and the second follower end tends to decrease, and the elastic member 330 may be a compression spring (corresponding to the pre-stretched length or the free initial length) that may hinder the force from decreasing the distance between the first follower end and the second follower end to hinder the shutter 220 from moving away from the target position W.

Understandably, under the driving without the driving member 210, since the position change needs to overcome the blocking force generated by the elastic member 330, the position stability of the opening and closing member 220 at the target position W can be ensured. When the driving force of the driving member 210 can overcome the blocking force of the elastic member 330, the opening and closing member 220 can be rotated away from the target position W to open the flow port S.

At this time, the locking assembly 300 is an elastically deformable structure composed of the first rotating member 310, the second rotating member 320 and the elastic member 330, and is stable and reliable in structure.

In some embodiments, referring to fig. 1,2 and 3, the other end of the second rotary member 320 is always located in the radial direction of the rotational path of the other end of the first rotary member 310.

The rotation path of the other end of the first rotary member 310 means a circular arc path provided around the first axial direction X1 in a plane perpendicular to the first axial direction X1, on which the other end of the second rotary member 320 is always located, that is, the other end of the first rotary member 310 and the other end of the second rotary member 320 are positionally changed only in the rotation radial direction of the first rotary member 310 (a direction perpendicular to and intersecting the first axial direction X1), so that the elastic member 330 is elastically deformed only in the rotation radial direction of the first rotary member 310. It will be appreciated that the radial direction of rotation is plural, and that there are plural radial directions similar to a circle.

It is understood that the elastic expansion and contraction direction of the elastic member 330 corresponds to the rotation radial direction, such as a linear spring.

At this time, the elastic member 330 may only need to have elastic deformation capable of being elastically deformed in one direction, and the elastic deformation degree of the elastic member 330 is concentrated in the elastic expansion direction, which helps to protect the elastic member 330, and the locking assembly 300 may provide more reliable elastic blocking force.

In the embodiment, the other end of the first rotating member 310 has a first sleeving part 311, the other end of the second rotating member 320 has a second sleeving part 322, the first sleeving part 311 extends along the direction perpendicular to the first axial direction X1 and is slidably sleeved with the second sleeving part 322, and the elastic member 330 is sleeved on the first sleeving part 311 and the second sleeving part 322.

The second sleeving part 322 can be sleeved on the first sleeving part 311 in a sliding manner along the extending direction of the first sleeving part 311, at this time, the second sleeving part 322 and the second sleeving part 322 can only change positions in the extending direction of the first sleeving part 311, and the elastic piece 330 sleeved on the second sleeving part and the second sleeving part can only elastically deform along the extending direction.

One of the second socket portion 322 and the first socket portion 311 may be a socket shaft, and the other may be a socket hole.

At this time, the second socket portion 322 and the first socket portion 311 are mutually socket-jointed, so that the installation of the elastic member 330 is realized, the other end of the first rotating member 310 and the other end of the second rotating member 320 are limited to be capable of being changed in position only in the rotation radial direction, and the structure is simple and easy to realize.

Of course, in other embodiments, in order to limit that the position between the other end of the first rotating member 310 and the other end of the second rotating member 320 can be changed only in the above-mentioned rotation radial direction, it is also possible that the other end of the first rotating member 310 and the other end of the second rotating member 320 are telescopically connected by a bellows member, and the elastic member 330 is sleeved on the bellows member.

Understandably, when the elastic member 330 is sleeved on the first sleeve-connecting portion 311 and the second sleeve-connecting portion 322, the elastic member 330 is limited between the first sleeve-connecting portion 311 and the second sleeve-connecting portion 322, and the elastic member 330 can be fixedly connected or abutted with the first sleeve-connecting portion 311 and the second sleeve-connecting portion 322, which is not limited.

In the embodiment, referring to fig. 1, 2 and 3, the second rotating member 320 further includes a connecting rod 321, one end of the connecting rod 321 is rotatably disposed on the air duct 100 around the second axis X2, and the second sleeving part 322 is rotatably disposed around the rotation direction X3 of the first axis X1 parallel to the second axis X2 opposite to the other end of the connecting rod 321.

The connecting rod 321 is rod-shaped, and the second socket portion 322 is disposed at one end of the connecting rod 321. The second sleeving part 322 can change the included angle with the connecting rod 321 under the limitation of the first sleeving part 311, and at this time, the second sleeving part 322 can rotate relative to the other end of the connecting rod 321, namely, the sleeving between the second sleeving part 322 and the first sleeving part 311 is supported. As can be appreciated, during the movement of the second socket portion 322 with the first socket portion 311, the rotation direction X3 moves around the first axial direction X1.

The rotation connection modes of the connecting rod 321 and the second sleeve joint portion 322 are various, and can be realized through structures such as a rotating shaft, a bearing and the like, which are not limited and described in detail herein.

Specifically, the second socket portion 322 includes a self-rotor portion 322a and a socket portion 322b provided on the self-rotor portion 322a, the socket portion 322b being socket-coupled with the first socket portion 311, the self-rotor portion 322a being rotatably connected with the link 321 about the rotation direction X3.

Of course, in other embodiments, the structure of the second rotating member 320 may be other forms, such as a structure of the multiple connecting rods 321 or other manners, and those skilled in the art may perform the setting based on the conventional design, in order to support the socket between the second socket portion 322 and the first socket portion 311.

In some embodiments, referring to fig. 4,5 and 6, the shutter 220 can be switched between two target positions W for independently closing the two flow ports S.

The defining shutter 220 has a first target position W1 and a second target position W2. When the shutter 220 is switched between the first target position W1 and the second target position W2, the coplanar position G is passed, and the elastic member 330 is at the maximum deformation amount, so that the movement resistance of the elastic member 330 to the shutter 220 is the maximum.

When the shutter 220 moves from the first target position W1 to the second target position W2, the blocking force of the elastic member 330 on the shutter 220 increases and decreases. Alternatively, the elastic member 330 may be compressed the most when in the coplanar position G. Alternatively, the elastic member 330 may be stretched by a maximum amount in the coplanar position G. And is not limited herein, depending on the actual arrangement.
