[0003] The air deflector is the air guiding structure of the air conditioner indoor unit. The air deflector extends or rotates under the drive of a moving component, so that the air deflector extends to a specific position or angle to guide the air supply direction of the air conditioner indoor unit and meet the user's demand for air supply comfort. In order to realize the extension and rotation of the air deflector, the existing moving components of the air deflector include an extension mechanism for driving the air deflector to extend and a rotation mechanism for driving the air deflector to rotate.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] In the prior art, the extension mechanism and the rotation mechanism of the air deflector are complex in structure, and there is currently no track plate with a simple structure that can be used in cooperation with the extension mechanism and the rotation mechanism of the air deflector to enable the air deflector to extend and rotate. Summary of the Invention

[0006] To have a basic understanding of some aspects of the disclosed embodiments, a simple summary is given below. This summary is not a general review, nor is it intended to identify key / important constituent elements or delineate the protection scope of these embodiments, but rather serves as a preamble to the subsequent detailed description.

[0007] The embodiments of the present disclosure provide a track plate, a moving component drive box, and an air conditioner indoor unit to solve the problem of the complex structure of the moving mechanism for driving the air deflector.

[0008] In some embodiments, a first track and a second track are provided on one surface of the track plate. The first track is used to define the movement trajectory of the active link member, and the second track is used to simultaneously define the movement trajectories of the active link member and the driven link member. Among them, the first track includes a first linear track and a first bifurcated track connected to the first linear track.

[0009] Optionally, the first bifurcated track includes a first branch track and a second branch track. The first branch track intersects with the connection end of the first linear track, and the first branch track extends in one direction; the second branch track intersects with the connection end of the first linear track, and the second branch track extends in the other direction.

[0010] Optionally, both the first branch track and the second branch track are arc-shaped.

[0011] Optionally, the second track includes a plurality of second straight tracks parallel to each other.

[0012] Optionally, the extending directions of the first straight track and the second straight track are the same.

[0013] Optionally, the second track includes three second straight tracks arranged in sequence, wherein the length of the second straight track disposed in the middle is greater than the lengths of the second straight tracks disposed on both sides.

[0014] Optionally, the first track is disposed above the second track.

[0015] In some embodiments, the movement component driving box includes an accommodation space formed by a cover plate and a bottom plate, and a movement component disposed in the accommodation space, wherein the track plate is disposed on the bottom plate.

[0016] Optionally, the movement component driving box further includes a connecting rod outlet. The movement component includes a driving element, a driving connecting rod member, and a driven connecting rod member drivingly connected to the driving element. The driving connecting rod member and the driven connecting rod member extend or retract in the connecting rod outlet under the driving of the driving element to drive the air deflector to move.

[0017] In some embodiments, an air conditioner indoor unit includes an air deflector, and movement component driving boxes as described above are disposed at both ends of the air deflector.

[0018] The track plate, the movement component driving box, and the air conditioner indoor unit provided by the embodiments of the present disclosure can achieve the following technical effects:

[0019] The track plate of the embodiment of the present application includes a first track and a second track. The first track can define the movement trajectory of the driving connecting rod member, and the second track can simultaneously define the movement trajectories of the driving connecting rod member and the driven connecting rod member. The first track includes a first straight track and a first bifurcated track that are connected and communicated. Thus, under the driving of the driving element of the air deflector, the first connecting rod first moves along the first straight track and then along the first bifurcated track. At the same time, under the limitation of the second track, the first connecting rod and the second connecting rod can move relative to each other to drive the air deflector to extend and then rotate.

[0044] The embodiments of the present disclosure provide a track slab 4, as Figure 1 shown.

[0045] In some embodiments, a first track and a second track 44 are arranged on one surface of the track slab 4. The first track is used to define the movement trajectory of the active link member, and the second track 44 is used to simultaneously define the movement trajectories of the active link member and the driven link member. Among them, the first track includes a first straight track 41 and a first bifurcated track connected to the first straight track 41.

[0046] The track slab 4 of the embodiments of the present application includes a first track and a second track 44. The first track can define the movement trajectory of the active link member, and the second track 44 can simultaneously define the movement trajectories of the active link member and the driven link member. The first track includes a connected straight track and a bifurcated track. Furthermore, driven by the driving element of the air deflector 6, the first link 2 first moves along the first straight track 41 and then along the first bifurcated track. At the same time, under the limitation of the second track 44, the first link 2 and the second link 3 can move relative to each other, driving the air deflector 6 to extend and then rotate. Among them, in the embodiments of the present application, the active link member is the first link 2, and the driven link member is the second link 3.

[0047] Optionally, the first bifurcated track includes a first branch track 42 and a second branch track 43. The first branch track 42 intersects with the connecting end of the first linear track 41, and the first branch track 42 extends in one direction; the second branch track 43 intersects with the connecting end of the first linear track 41, and the second branch track 43 extends in the other direction.

[0048] As Figure 1 shown, the first branch track 42 and the second branch track 43 respectively intersect with the first linear track 41, and the extending directions of the first branch track 42 and the second branch track 43 are different. Optionally, the first linear track 41 includes an initial end and a connecting end. The first branch track 42 and the second branch track 43 are respectively connected to the connecting end of the first linear track 41 and extend in different directions. Optionally, when the first link 2 moves from the first linear track 41 to the first branch track 42, the first link 2 and the second link 3 perform relative movement, and drive the air deflector 6 to open upward; when the first link 2 moves from the first linear track 41 to the second branch track 43, the first link 2 and the second link 3 perform relative movement, and drive the air deflector 6 to open downward. Optionally, the first linear track 41, the first branch track 42, and the second branch track 43 form a chevron track, as Figure 1 shown.

[0049] Optionally, both the first branch track 42 and the second branch track 43 are arc-shaped. In this way, the movement direction of the first link 2 can be changed, and relative movement with the second link 3 can be generated, so that the air deflector 6 can be opened upward or downward.

[0050] Optionally, the first link 2 is provided with a first end slider 211 and a first cooperation slider 212 that limit the movement of the first link 2. Among them, the first end slider 211 slides in the first linear track 41, the first branch track 42, and the second branch track 43, and the first cooperation slider 212 slides in the second track 44. The first end slider 211 and the first cooperation slider 212 jointly limit the movement track of the first link 2.

[0051] Optionally, the second track 44 includes a plurality of mutually parallel second linear tracks.

[0052] The second track 44 includes a second linear track that defines the linear movement of the first link 2 and the second link 3. The first link 2 and the second link 3 move linearly in synchronization. Furthermore, the first link 2 and the second link 3 together drive the air deflector 6 to move linearly, extending from the air outlet to the first preset position, or driving the air deflector 6 to retract from the first preset position to the air outlet. Optionally, the first preset position is the position where the air deflector 6 extends out of the air conditioner and is about to start rotating. At this time, there is a certain distance between the air deflector 6 and the air outlet, and the air deflector 6 can be opened upward or downward at the first preset position. Optionally, the rotation position of the air deflector 6 may not be limited to the first preset position. The first preset position can also be understood as the initial position of the rotation of the air deflector 6. The rotation of the air deflector 6 can be understood as rotating while extending.

[0053] When the first link 2 is driven by the driving element of the air deflector 6 and moves from the first linear track 41 to the first bifurcated track, the movement direction of the first link 2 changes. At this time, the second link 3 continues to move linearly along the second linear track. Therefore, a relative movement occurs between the first link 2 and the second link 3, and both the first link 2 and the second link 3 are rotatably connected to the air deflector 6. Furthermore, the first link 2 and the second link 3 drive the air deflector 6 to rotate.

[0054] Optionally, the extending direction of the first linear track 41 is the same as that of the second linear track. Both the first linear track 41 and the second linear track are linear tracks and have the same extending direction. In this way, the first link 2 and the second link 3 can move linearly in synchronization and drive the air deflector 6 to extend out of the air conditioner. Among them, this extending direction is the translation direction during the process of the air deflector 6 extending out of the air conditioner to the first preset position.

[0055] Optionally, the second track 44 includes three second linear tracks arranged in sequence. Among them, the length of the second linear track disposed in the middle is greater than the lengths of the second linear tracks disposed on both sides.

[0056] Optionally, the second connecting rod 3 includes a second limiting slider 33, a third limiting slider 34 and a fourth limiting slider 35 moving along the second track 44, and the second limiting slider 33, the third limiting slider 34 and the fourth limiting slider 35 are arranged in a triangle, which improves the limiting effect of the second connecting rod 3. Correspondingly, the second limiting slider 33, the third limiting slider 34 and the fourth limiting slider 35 move in the above three second linear tracks respectively, the second limiting slider 33 corresponds to the second linear track in the middle, and the third limiting slider 34 and the fourth limiting slider 35 correspond to the second linear tracks on both sides respectively. When the air guide plate is closed, the second limiting slider 33, the third limiting slider 34 and the fourth limiting slider 35 are respectively located at the starting ends of the three second linear tracks, and the starting end is an end close to the first track. The second limiting slider 33, the third limiting slider 34 and the fourth limiting slider 35 are arranged in a triangle, so that, correspondingly, the length of the second linear track set in the middle needs to be greater than the length of the second linear tracks set on both sides.

[0057] Optionally, the first track is disposed on the upper portion of the second track 44. In this way, the air guide plate 6 can first move linearly along the first linear track 41, and at the same time, under the limitation of the second track 44, the first connecting rod 2 and the second connecting rod 3 move relative to each other, thereby driving the air guide plate 6 to rotate.

[0058] The present application also provides a motion component driving box, in which a motion component is arranged. Figure 10 As shown, the motion components are Figure 7 shown.

[0059] In some embodiments, the motion component driving box includes a receiving space formed by a cover plate and a bottom plate, and a motion component disposed in the receiving space, wherein the track plate 4 is disposed on the bottom plate. Optionally, the track plate 4 and the bottom plate may be an integrated structure.

[0060] Optionally, the motion assembly driving box further includes a connecting rod extension port, and the motion assembly includes a driving element and an active connecting rod member and a driven connecting rod member that are transmission-connected to the driving element, wherein the active connecting rod member and the driven connecting rod member extend or retract in the connecting rod extension port under the drive of the driving element to drive the movement of the air guide plate 6. That is, the first connecting rod 2 and the second connecting rod 3 can extend or retract in the connecting rod extension port under the drive of the driving element to drive the movement of the air guide plate 6.

[0061] In the embodiment of the present application, optionally, the driving element may be a crank element 1 , the active connecting rod member may be the first connecting rod 2 , and the driven connecting rod member may be the second connecting rod 3 .

[0062] Optionally, the motion assembly provided in the embodiment of the present disclosure further includes a motor 5, such as Figure 10As shown. Optionally, the motor 5 is a bidirectional drive motor. By controlling the rotation direction of the motor 5, the moving component can drive the air deflector 6 to extend or retract from the air outlet; also, by controlling the rotation direction of the motor 5, the moving component can drive the air deflector 6 to open upward or downward to adapt to the cooling or heating mode of the air conditioner. Optionally, the motor 5 is a stepper motor.

[0063] The crank element 1 provided by the embodiment of the present disclosure includes a driving surface 101 connected to the motor 5 and a rotating surface 102 disposed opposite to the driving surface 101. Among them, the rotating surface 102 is provided with a first transmission shaft 11 and a second transmission shaft 12. The first transmission shaft 11 is disposed at the end of the rotating surface 102 to increase the driving extension distance of the first link 2, and the second rotating shaft is disposed in the middle of the rotating surface 102. Optionally, the driving surface 101 is further provided with a reinforcing rib 13 to increase the driving force of the crank element 1. Optionally, a reinforcing column 14 is further disposed at a position corresponding to the second transmission shaft 12 on the driving surface 101 to increase the abutting force of the second transmission shaft 12. Optionally, the crank element 1 includes a rotating disc and a rotating rod connected to each other, and the first transmission shaft 11 is disposed at the end of the rotating rod.

[0064] The structure of the crank element is as Figure 6 shown. The first transmission shaft 11 is disposed at the end of the rotating rod, increasing the distance between the first transmission shaft 11 and the rotation center, increasing the radius of the virtual circle generated by the movement of the first transmission shaft 11, so that the air deflector 6 can extend to a farther distance from the air outlet, that is, increasing the distance between the first preset distance and the air outlet, enabling the air deflector 6 to have sufficient rotation space, and further enabling the air deflector 6 to have sufficient space to open upward or downward.

[0065] Optionally, the crank element 1 is provided with a first transmission shaft 11; one end of the first link 2 is connected to the air deflector 6, and the first link 2 is provided with a first slideway 201 for the first transmission shaft 11 to slide, so that the crank element 1 is in transmission connection with the first link 2; one end of the second link 3 is connected to the air deflector 6; the track plate 4 can define the movement trajectories of the first link 2 and the second link 3. The first link 2 moves under the drive of the crank element 1, and the first link 2 and the second link 3 move under the limitation of the track plate 4, driving the air deflector 6 to extend to the first preset position and then rotate.

[0066] Optionally, the transmission mode of the motion component provided by the embodiments of the present disclosure is that the crank element 1 is in transmission connection with the first connecting rod 2. The crank element 1 can drive the first connecting rod 2 to move. The first connecting rod 2 is connected to the air deflector 6, and the first connecting rod 2 can drive the air deflector 6 to move. The air deflector 6 is connected to the second connecting rod 3, and the air deflector 6 can drive the second connecting rod 3 to move. It can be seen that the driving force for the movement of the first connecting rod 2 and the second connecting rod 3 comes from the crank element 1. The movement mode of the motion component provided by the embodiments of the present disclosure can also be described as that the crank element 1 directly drives the first connecting rod 2 to move, and the crank element 1 indirectly drives the second connecting rod 3 to move.

[0067] Optionally, the connection modes between the air deflector 6 and the first connecting rod 2 and the second connecting rod 3 are both rotatable connections. After the first connecting rod 2 and the second connecting rod 3 drive the air deflector 6 to move to the first preset position, it rotates. Optionally, the first connecting rod 2 is further provided with a first connecting shaft 204, and the first connecting shaft 204 is inserted into the first mounting portion 611 on the mounting seat 61 of the air deflector 6 to realize the rotatable connection between the first connecting rod 2 and the air deflector 6. Optionally, the second connecting rod 3 is further provided with a second connecting shaft 32, and the second connecting shaft 32 is inserted into the second mounting portion 612 on the mounting seat 61 of the air deflector 6 to realize the rotatable connection between the second connecting rod 3 and the air deflector 6.

[0068] Optionally, under the limitation of the track plate 4, the first connecting rod 2 and the second connecting rod 3 first move linearly at the same time. The first connecting rod 2 and the second connecting rod 3 jointly drive the air deflector 6 to move linearly, so that the air deflector 6 linearly extends from the closed state to the first preset position; then, the movement direction of the first connecting rod 2 changes under the limitation of the track plate 4, and the second connecting rod 3 continues to move linearly. At this time, relative movement occurs between the first connecting rod 2 and the second connecting rod 3, and the first connecting rod 2 and the second connecting rod 3 jointly drive the air deflector 6 to rotate.

[0069] During the rotation of the crank element 1, the first transmission shaft 11 itself does not rotate, but rotates along the virtual or physical rotation center of the crank element 1 under the drive of the crank element 1. Optionally, the movement trajectory formed by the first transmission shaft 11 is a circle with the rotation center of the crank element 1 as the center and the distance from the first transmission shaft 11 to the rotation center as the radius.

[0070] Optionally, the first connecting rod 2 includes a first slideway plate surface provided with a first slideway 201 and a first slider plate surface corresponding to the first slideway plate surface. Among them, the first slider plate surface is provided with a first end slider 211 and a first cooperative slider 212 that limit the movement of the first connecting rod 2. Among them, the first end slider 211 slides in the first straight track 41, the first branch track 42, and the second branch track 43, and the first cooperative slider 212 slides in the second track 44. The first end slider 211 and the first cooperative slider 212 jointly limit the movement trajectory of the first connecting rod 2. As Figure 2 and Figure 3as shown

[0071] Optionally, the first slider plate surface of the first link 2 is in direct contact with the second link 3, and a first contact flange 213 is provided on the first slider plate surface of the first link 2, reducing the contact area between the two links and the frictional force when the two links move relative to each other. Optionally, a first reinforcing beam 214 is further provided on the first slider plate surface.

[0072] Optionally, the second link 3 is provided with a through slideway 31 through which the first cooperative slider 212 of the first link 2 passes. The second link 3 is disposed between the first link 2 and the track plate 4. The provision of the through slideway 31 on the second link 3 enables the first cooperative slider 212 of the first link 2 to move under the limitation of the second track 44 of the track plate 4 through the through slideway 31. Optionally, the track of the first cooperative slider 212 on the track plate 4 is a second straight track.

[0073] Optionally, the first link 2 is further provided with a first branch slideway 202 and a second branch slideway 203 for the second transmission shaft 12 to slide and having different extending directions. Among them, when the crank element 1 rotates to the second preset position along the first direction, the second transmission shaft 12 of the crank element 1 abuts against the first branch slideway 202, driving the first link 2 to move along the first branch track 42, so that the moving assembly drives the air deflector 6 to open upward. When the crank element 1 rotates to the third preset position along the second direction, the second transmission shaft 12 of the crank element 1 abuts against the second branch slideway 203, driving the first link 2 to move along the second branch track 43, so that the moving assembly drives the air deflector 6 to open downward.

[0074] Optionally, the first slideway 201 is a straight slideway, the first branch slideway 202 and the second branch slideway 203 are both disposed on the same side of the first slideway 201, and the first branch slideway 202 and the second branch slideway 203 both intersect with the first slideway 201. Optionally, the first branch slideway 202 and the second branch slideway 203 are respectively disposed at both ends of the center line of the first slideway 201.

[0075] Optionally, the depth of the first branch slideway 202 and the depth of the second branch slideway 203 can be the same, and the depth of the first branch slideway 202 and the depth of the second branch slideway 203 match the length of the second transmission shaft 12 of the crank element 1, and the depth of the first slideway 201 matches the length of the first transmission shaft 11 of the crank element 1. The length of the first transmission shaft 11 is greater than the length of the second transmission shaft 12. During the rotation of the first transmission shaft 11, the second transmission shaft 12, as the middle transmission shaft, will also move within the virtual circle formed by the rotation of the first transmission shaft 11. The length of the second transmission shaft 12 is less than the length of the first transmission shaft 11, that is, the depth of the first branch slideway 202 and the depth of the second branch slideway 203 are both less than the depth of the first slideway 201. In this way, during the rotation of the crank element 1, it is beneficial for the second transmission shaft 12 to enter the motion track, that is, to enter the first branch slideway 202 or the second branch slideway 203 under the driving force of the crank element 1, and the second transmission shaft 12 can maintain a state of abutting against the first branch slideway 202 or the second branch slideway 203.

[0076] When the crank element 1 rotates to the second preset position along the first direction, the second transmission shaft 12 of the crank element 1 abuts against the first branch slideway 202, and the second transmission shaft 12 of the crank element 1 generates an abutting force that drives the first connecting rod 2 to move along the first branch track 42, so that the movement track of the first connecting rod 2 is to move along the first branch track 42, and then the movement assembly drives the air deflector 6 to open upward; when the crank element 1 rotates to the third preset position along the second direction, the second transmission shaft 12 of the crank element 1 abuts against the second branch slideway 203, and the second transmission shaft 12 of the crank element 1 generates an abutting force that drives the first connecting rod 2 to move along the second branch track 43, so that the movement track of the first connecting rod 2 is to move along the second branch track 43, and then the movement assembly drives the air deflector 6 to open downward. Optionally, the first direction can be the counterclockwise direction, and the second direction is the clockwise direction. Among them, the second preset position is the position where the second transmission shaft 12 just abuts against the starting end of the first branch slideway 202 when the crank element 1 rotates along the first direction, that is, the counterclockwise direction; the third preset position is the position where the second transmission shaft 12 just abuts against the starting end of the second branch slideway 203 when the crank element 1 rotates along the second direction, that is, the clockwise direction.

[0077] Optionally, when the crank element 1 rotates to the second preset position along the first direction, the first included angle between the connection line formed by the first transmission shaft 11 of the crank element 1 and the rotation center of the crank element 1 and the first straight track 41 is greater than 85°; among them, the first included angle can be Figure 8The schematic of α therein. Optionally, when the crank element 1 rotates in the second direction to the third preset position, the second included angle between the connecting line formed by the first transmission shaft 11 of the crank element 1 and the rotation center of the crank element 1 and the first linear track 41 is greater than 85°.

[0078] The first branch slideway 202 and the second branch slideway 203 respectively apply abutting forces in different directions to the second transmission shaft 12 to respectively urge the first connecting rod 2 to move along the first branch track 42 and the second branch track 43, thereby driving the air deflector 6 to open in a preset direction. Optionally, the time node when the second transmission shaft 12 of the crank element 1 enters the first branch slideway 202 or the second branch slideway 203 is prior to the time node when the first connecting rod 2 moves along the first branch track 42 or the second branch track 43, so that the first connecting rod 2 changes its movement direction under the action of the abutting force of the second transmission shaft 12 of the crank element 1. Optionally, the first branch slideway 202 includes a first linear abutting portion that abuts against the second transmission shaft, wherein the first linear abutting portion is perpendicular to the first slideway 201, and the second branch slideway 203 includes a second linear abutting portion that abuts against the second transmission shaft, wherein the second linear abutting portion is perpendicular to the first slideway 201.

[0079] In some embodiments, an air conditioner indoor unit includes an air deflector, wherein movement component drive boxes as described above are provided at both ends of the air deflector. In this way, the air deflector can move more smoothly. Optionally, the air conditioner indoor unit further includes a housing 7, an air outlet is provided on the housing 7, and the air deflector 6 can be extended or retracted from the air outlet under the drive of the movement component.

[0080] The driving method for extending and rotating the air deflector 6 by using the movement component provided in the embodiments of the present disclosure is as follows:

[0081] When the air deflector 6 is in the closed state, the initial state of the movement component is as Figure 7 shown. The crank element 1 rotates in the first direction, the first transmission shaft 11 of the crank element 1 slides in the first slideway 201 of the first connecting rod 2, the first connecting rod 2 makes a linear motion under the limitation of the first end slider 211 and the first cooperating slider 212, and at the same time, the second connecting rod 3 makes a linear motion under the limitation of the second track 44. Furthermore, the first connecting rod 2 and the second connecting rod 3 drive the air deflector 6 to linearly extend to the first preset position. When the crank element 1 rotates in the first direction, the first preset position is as Figure 8 shown.

[0082] After reaching the first preset position, the second transmission shaft 12 of the crank element 1 enters the first branch slideway 202, and a contact force is generated between the second transmission shaft 12 and the first branch slideway 202, thereby controlling the first end slider 211 of the first connecting rod 2 to move into the first branch track 42. At this time, the first cooperation slider 212 of the first connecting rod 2 continues to move in a straight line. The first connecting rod 2 changes its movement direction under the limitation of the first end slider 211 and the first cooperation slider 212. The second connecting rod 3 continues to move in a straight line. Therefore, the air deflector 6 is driven upward to open under the combined drive of the first connecting rod 2 and the second connecting rod 3, as Figure 9 and Figure 10 shown.

[0083] After reaching the first preset position, the second transmission shaft 12 of the crank element 1 enters the second branch slideway 203, and a contact force is generated between the second transmission shaft 12 and the second branch slideway 203, thereby controlling the first end slider 211 of the first connecting rod 2 to move into the second branch track 43. At this time, the first cooperation slider 212 of the first connecting rod 2 continues to move in a straight line. The first connecting rod 2 changes its movement direction under the limitation of the first end slider 211 and the first cooperation slider 212. The second connecting rod 3 continues to move in a straight line. Therefore, the air deflector 6 is driven downward to open under the combined drive of the first connecting rod 2 and the second connecting rod 3, as Figure 11 and Figure 12 shown.

[0084] Optionally, the air conditioner indoor unit provided by the embodiment of the present disclosure is a large air deflector type air conditioner indoor unit. The air deflector 6 of the air conditioner indoor unit provided by the embodiment of the present disclosure can completely close the air outlet when the air deflector 6 is in the closed state. Optionally, the air conditioner indoor unit provided by the embodiment of the present disclosure can also be a cabinet type or a duct type, etc.
