[0035] The following details the embodiments of the present disclosure, and the examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0036] The supporting wheel of the embodiment of the present disclosure is used to support the drive bar. As Figure 1 and Figure 2 shown, the supporting wheel 42 includes a rotating shaft 421 and a wheel body 422, and the wheel body 422 is connected to the rotating shaft 421. An annular limiting groove 4221 is provided on the outer peripheral surface of the wheel body 422.

[0037] Optionally, as Figures 3 to 9As shown, the driving assembly 3 includes a driving member 31, a swing rod 32, and a driving bar 33. The driving member 31 is connected to the swing rod 32 to drive the swing rod 32 to swing. The driving bar 33 is connected to the swing rod 32, and the driving bar 33 is used to be connected to the sliding door 2 to drive the sliding door 2 to open or close the air outlet 11. The driving bar 33 is provided with a guiding portion 331, and the lower portion of the guiding portion 331 is embedded in the limiting groove 4221.

[0038] During specific use, the driving bar 33 is connected to the sliding door 2. The driving member 31 drives the swing rod 32 to swing, and the swing rod 32 drives the driving bar 33 to move, so that the driving bar 33 drives the sliding door 2 to open or close the air outlet 11. By embedding the lower portion of the driving bar 33 in the limiting groove 4221, during the process of the driving bar 33 driving the sliding door 2 to slide, the position of the driving bar 33 in the axial direction of the supporting wheel 42 is limited by the limiting groove 4221, avoiding the driving bar 33 from shaking on the supporting wheel 42, thereby avoiding the sliding door 2 from shaking during the sliding process and improving the movement stability of the sliding door 2.

[0039] For example, the axial direction of the supporting wheel 42 is consistent with the inside-outside direction, avoiding the sliding door 2 from shaking in the inside-outside direction during the sliding process. Among them, the direction close to the swing center of the swing rod 32 is defined as inwards, and the direction away from the swing center of the swing rod 32 is defined as outwards. The inside-outside direction is as Figure 2 , Figure 3 and Figure 9 shown.

[0040] In some embodiments, the wheel body 422 is a rigid member, and the supporting wheel 42 is coated with a flexible layer.

[0041] Among them, the flexible layer can be a rubber layer. The flexible layer can be vulcanized and fixed on the wheel body 422, or bonded and fixed on the wheel body 422.

[0042] By coating the outside of the wheel body 422 with a flexible layer, it can achieve the effects of shock absorption and noise reduction, further improving the movement stability of the sliding door 2 and reducing the noise during the movement of the sliding door 2.

[0043] Optionally, as Figure 1 and Figure 2 shown, the limiting groove 4221 is an arc-shaped groove.

[0044] By setting the limiting groove 4221 as an arc-shaped groove, the stress concentration problem of the wheel body 422 can be reduced, and the structural strength and reliability of the supporting wheel 42 can be improved.

[0045] As Figures 5 to 8 shown, the sliding door driving mechanism of the embodiment of the present disclosure includes the above-mentioned driving assembly 3 and the above-mentioned guiding assembly 4.

[0046] To make the technical solution of the present disclosure easier to understand, the following takes the width direction of the air outlet 11 being consistent with the left-right direction and the height direction of the air outlet 11 being consistent with the up-down direction as an example to further describe the technical solution of the present disclosure. Among them, the up-down direction is as Figure 11 shown, and the left-right direction is as Figures 5 to 8 , Figure 10 shown.

[0047] For example, when the sliding door driving mechanism drives the sliding door 2 to slide to the left, the air outlet 11 is opened; when the sliding door driving mechanism drives the sliding door 2 to slide to the right, the air outlet 11 is closed.

[0048] Optionally, an installation bracket is provided inside the air conditioner 100, and the driving member 31 is connected to the installation bracket. Among them, the driving member 31 can be a motor.

[0049] Optionally, as Figure 3 shown, the guiding assembly 4 includes a guiding frame 41, a supporting wheel 42 is rotatably connected to the guiding frame 41, the guiding frame 41 is provided with a guide rail 411 extending along the extending direction of the driving strip 33, and the guiding portion 331 is in guiding cooperation with the guide rail 411. Among them, the supporting wheel 42 and the guiding frame 41 can be welded, clamped or connected by fasteners, and the fasteners can be bolts, screws or rivets.

[0050] For example, the extending direction of the driving strip 33 is consistent with the circumferential direction of the housing 1, and the guide rail 411 extends along the circumferential direction of the housing 1.

[0051] By providing the guide rail 411 on the guiding frame 41 and using the guiding cooperation between the guiding portion 331 of the driving strip 33 and the guide rail 411, the skew of the driving strip 33 during the movement process can be effectively avoided, and the movement stability of the sliding door 2 can be further improved.

[0052] Among them, the guiding frame 41 can be connected to the housing 1 of the air conditioner 100. For example, the guiding frame 41 is connected to the top cover of the air conditioner 100.

[0053] Optionally, as Figure 2 shown, the guide rail 411 includes a first guide rail portion 4111 and a second guide rail portion 4112 arranged at intervals along the height direction of the air outlet 11, and the first guide rail portion 4111 and the second guide rail portion 4112 clamp the guiding portion 331.

[0054] For example, as Figure 2 shown, the first guide rail portion 4111 is arranged above the second guide rail portion 4112, and in the up-down direction, the guiding portion 331 is clamped between the first guide rail portion 4111 and the second guide rail portion 4112.

[0055] By clamping the guiding portion 331 between the first guide rail portion 4111 and the second guide rail portion 4112, the position of the guiding portion 331 can be restricted in the height direction of the air outlet 11, preventing the driving bar 33 from skewing in the height direction of the air outlet 11 and improving the movement stability of the sliding door 2.

[0056] Optionally, as Figure 2 and Figure 3 shown, the first guide rail portion 4111 is provided with a first guide rail groove with the notch facing the second guide rail portion 4112, and the second guide rail portion 4112 is provided with a second guide rail groove with the notch facing the first guide rail portion 4111. The guiding portion 331 includes a first portion 3311 and a second portion 3312 arranged at intervals in the height direction of the air outlet 11. The first portion 3311 is arranged in the first guide rail groove, and the second portion 3312 is arranged in the second guide rail groove.

[0057] For example, as Figure 2 and Figure 3 shown, the first guide rail groove is arranged above the second guide rail groove, the notch of the first guide rail groove faces downward, the notch of the second guide rail groove faces upward, the first portion 3311 is arranged above the second portion 3312, the first portion 3311 is arranged in the first guide rail groove, and the second portion 3312 is arranged in the second guide rail groove.

[0058] Optionally, as Figure 3 shown, the guiding assembly 4 further includes at least one limiting wheel 43, and the limiting wheel 43 is rotatably connected to the guiding frame 41. The limiting wheel 43 is arranged on the side away from the supporting wheel 42 in the height direction of the air outlet 11, and the limiting wheel 43 presses against the guiding portion 331. Among them, the limiting wheel 43 and the guiding frame 41 can be welded, clamped or connected by fasteners, and the fasteners can be bolts, screws or rivets.

[0059] For example, as Figure 3 shown, the limiting wheel 43 is arranged above the supporting wheel 42, and the limiting wheel 43 presses downward against the guiding portion 331.

[0060] By providing the limiting wheel 43, the position of the guiding portion 331 can be limited in the height direction of the air outlet 11, thereby preventing the driving bar 33 from jumping in the height direction of the air outlet 11 and further improving the movement stability of the sliding door 2.

[0061] Optionally, the outer peripheral surface of the limiting wheel 43 is a cylindrical surface.

[0062] By setting the outer peripheral surface of the limiting wheel as a cylindrical surface, it is convenient for the processing and manufacturing of the limiting wheel 43 and is beneficial to reducing the cost of the sliding door driving mechanism.

[0063] Optionally, the limiting wheel 43 and the supporting wheel 42 clamp the guiding portion 331 in the height direction of the air outlet 11.

[0064] By clamping the limiting wheel 43 and the supporting wheel 42 along the height direction of the air outlet 11 to hold the guiding portion 331, the position of the guiding portion 331 can be restricted in the height direction of the air outlet 11, preventing the driving bar 33 from skewing in the height direction of the air outlet 11 and improving the movement stability of the sliding door 2.

[0065] Optionally, as Figure 3 shown, the guiding assembly 4 further includes at least one anti-wear wheel 44 which is rotatably connected to the guiding frame 41. The anti-wear wheel 44 is disposed on one side of the driving bar 33 close to the swing center of the swing rod 32 and abuts against the guiding portion 331 along the direction away from the swing center of the swing rod 32. Among them, the anti-wear wheel 44 and the guiding frame 41 can be welded, clamped or connected by fasteners, and the fasteners can be bolts, screws or rivets.

[0066] By providing the anti-wear wheel 44 and using the anti-wear wheel 44 to abut against the guiding portion 331 along the direction away from the swing center of the swing rod 32, the frictional force between the driving bar 33 and the guiding assembly 4 can be reduced. Thus, when the power of the driving member 31 is small, the sliding door 2 can be driven to slide, reducing the cost of the sliding door driving mechanism.

[0067] For example, as Figures 5 to 8 shown, the angular range of the air outlet 11 is within the range of α, and the swing range of the swing rod 32 is outside the range of α.

[0068] By setting the swing range of the swing rod 32 on one side in the width direction of the air outlet 11, it is ensured that the swing of the swing rod 32 does not occupy the space in the height direction of the air outlet 11, that is, there is no need to reserve an avoidance space for the swing of the swing rod 32 in the height direction of the air outlet 11. Thus, the height of the air outlet 11 is not restricted by the swing rod 32, and the height of the air outlet 11 can be set higher, increasing the air outlet area of the air outlet 11.

[0069] In addition, by setting the swing range of the swing rod 32 on one side in the width direction of the air outlet 11, when the air outlet 11 is opened, it is also possible to prevent the user from seeing the swing rod 32 from outside the air outlet 11, improving the aesthetic appearance of the air conditioner 100 and thus enhancing the user experience.

[0070] In some embodiments, as Figures 5 to 8 shown, the swing rod 32 is connected to the end of the driving bar 33 away from the sliding door 2, and the guiding assembly 4 is disposed between the two ends in the extending direction of the driving bar 33.

[0071] It can be understood that connecting the swing rod 32 to the end of the driving strip 33 away from the sliding door 2 can keep the distance between the swing rod 32 and the sliding door 2 relatively large. As a result, the distance between the swing rod 32 and the air outlet 11 during the swinging process of the swing rod 32 is relatively large, making it easier to control the swinging range of the swing rod 32 on the same side in the width direction of the air outlet 11. However, at this time, the driving strip 33 is unevenly stressed in its length direction, and the driving strip 33 is prone to deflection during movement.

[0072] By arranging the guiding assembly 4 between the two ends of the driving strip 33, the driving strip 33 can be effectively guided, avoiding deflection during the movement of the driving strip 33 and improving the movement stability of the sliding door 2.

[0073] In some embodiments, the swing rod 32 and the driving strip 33 are integrally formed.

[0074] For example, the swing rod 32 and the driving strip 33 are integrally injection molded.

[0075] By integrally forming the swing rod 32 and the driving strip 33, the number of components of the sliding door driving mechanism can be reduced, which is beneficial to improving the assembly efficiency of the sliding door driving mechanism and reducing the cost of the sliding door driving mechanism.

[0076] Of course, in some other embodiments, the swing rod 32 and the driving strip 33 can also be separately arranged.

[0077] It can be understood that the sliding door 2, the swing rod 32, the driving strip 33, etc. will deform under conditions such as thermal expansion and contraction. For example, the swing rod 32 elongates or shortens. When the swing rod 32 and the driving strip 33 are integrally formed, the above deformation will cause a force in the direction of approaching or departing from the swing center of the swing rod 32 at the connection between the swing rod 32 and the driving strip 33, thereby causing the sliding door 2 to deviate from the arc surface of the air outlet 11, resulting in jamming of the movement of the sliding door 2 and affecting the movement stability of the sliding door 2.

[0078] In some other embodiments, as Figures 5 to 8 shown,

[0079] the swing rod 32 and the driving strip 33 are movably connected to release the force at the connection between the swing rod 32 and the driving strip 33 in the direction of approaching or departing from the swing center of the swing rod 32.

[0080] By movably connecting the swing rod 32 and the driving strip 33, when the sliding door 2, the swing rod 32, the driving strip 33, etc. deform under conditions such as thermal expansion and contraction, the force at the connection between the swing rod 32 and the driving strip 33 can be released in the direction of approaching or departing from the swing center of the swing rod 32, avoiding the sliding door 2 from deviating from the arc surface of the air outlet 11, thereby preventing the sliding door 2 from getting stuck during movement and improving the movement stability of the sliding door 2.

[0081] In some embodiments, such as Figure 5 and Figure 6 shown, the sliding door drive mechanism includes a connecting member 34, and both ends of the connecting member 34 are rotatably connected to the swing rod 32 and the drive bar 33 respectively, that is, both ends of the connecting member 34 are hinged to the swing rod 32 and the drive bar 33 respectively, wherein the hinge axis extends in the up and down direction.

[0082] By rotatably connecting both ends of the connecting member 34 to the swing rod 32 and the drive bar 33 respectively, during the rotation of the swing rod 32, relative rotation can occur between the connecting member 34 and the swing rod 32, and between the connecting member 34 and the drive bar 33, so as to release the acting force at the connection of the swing rod 32 and the drive bar 33 in the direction of approaching or departing from the swing center of the swing rod 32, and improve the movement stability of the sliding door 2.

[0083] Optionally, the connecting member 34 is a connecting rod.

[0084] In other embodiments, the swing rod 32 is slidably connected to the drive bar 33, and the sliding direction is close to or away from the swing center of the swing rod 32.

[0085] By slidably connecting the swing rod 32 to the drive bar 33, and the sliding direction is close to or away from the swing center of the swing rod 32, during the rotation of the swing rod 32, the swing rod 32 can slide relative to the drive bar 33, so as to release the acting force at the connection of the swing rod 32 and the drive bar 33 in the direction of approaching or departing from the swing center of the swing rod 32, and improve the movement stability of the sliding door 2.

[0086] In some embodiments, such as Figures 7 to 10 shown, the sliding door drive mechanism includes a connecting member 34, and the connecting member 34 is connected to the drive bar 33. One of the connecting member 34 and the swing rod 32 is provided with a chute 321, and the other of the connecting member 34 and the swing rod 32 is provided with a slider 341, and the slider 341 is slidably connected to the chute 321.

[0087] For example, as Figure 9 shown, the connecting member 34 is integrally formed with the drive bar 33, and the connecting member 34 is provided with a slider 341. As Figure 10 shown, the swing rod 32 is provided with a chute 321, and the chute 321 extends along the length direction of the swing rod 32. During the rotation of the swing rod 32, the slider 341 can slide along the extending direction of the chute 321, so as to release the acting force at the connection of the swing rod 32 and the drive bar 33 in the direction of approaching or departing from the swing center of the swing rod 32, and improve the movement stability of the sliding door 2. Optionally, as Figure 6 shown, the connecting member 34 is integrally formed with the drive bar 33.

[0088] For example, the connecting member 34 and the drive bar 33 are integrally injection molded.

[0089] By integrally forming the connecting member 34 with the driving bar 33, the number of components of the sliding door driving mechanism can be reduced, which is beneficial to improving the assembly efficiency of the sliding door driving mechanism and reducing the cost of the sliding door driving mechanism.

[0090] Of course, in some other embodiments, the connecting member 34 and the driving bar 33 may also be separately provided.

[0091] In some other embodiments, the connecting member 34 is connected to the swing bar 32. One of the connecting member 34 and the driving bar 33 is provided with a sliding groove 321, and the other of the connecting member 34 and the driving bar 33 is provided with a sliding block 341. The sliding block 341 is slidably connected to the sliding groove 321.

[0092] For example, the connecting member 34 is integrally formed with the swing bar 32, and the connecting member 34 is provided with a sliding block 341, and the driving bar 33 is provided with a sliding groove 321. During the rotation of the swing bar 32, the sliding block 341 can slide along the extension direction of the sliding groove 321, so as to release the acting force at the connection between the swing bar 32 and the driving bar 33 in the direction of approaching or departing from the swing center of the swing bar 32, and improve the movement stability of the sliding door 2.

[0093] In some other embodiments, the connecting member 34 may not be provided, and the swing bar 32 is directly slidably connected to the driving bar 33. For example, the driving bar 33 is provided with a sliding groove, and a part of the swing bar 32 is slidably arranged in the sliding groove in the direction of approaching or departing from the swing center of the swing bar 32. At this time, by directly sliding the swing bar 32 relative to the driving bar 33, the acting force at the connection between the swing bar 32 and the driving bar 33 is released in the direction of approaching or departing from the swing center of the swing bar 32.

[0094] Optionally, the driving bar 33 includes a first section and a second section arranged in sequence along its extension direction. The size of the second section in the height direction of the air outlet 11 is larger than the size of the first section in the height direction of the air outlet 11. The swing bar 32 is connected to the first section, and the second section is used to be connected to the sliding door 2.

[0095] By connecting the second section with a larger size to the sliding door 2, the connection area between the driving bar 33 and the sliding door 2 can be increased, and the connection reliability between the sliding door driving mechanism and the sliding door 2 can be improved.

[0096] The air conditioner of the embodiment of the present disclosure includes a housing 1, a sliding door 2 and a sliding door driving mechanism. The housing 1 is provided with an air outlet 11, and the sliding door 2 is slidably arranged at the air outlet 11. The sliding door driving mechanism is the sliding door driving mechanism of any of the above embodiments. The driving bar 33 is connected to the sliding door 2 to drive the sliding door 2 to slide along the arc surface of the air outlet 11.

[0097] Among them, the air conditioner 100 is a floor-standing air conditioner cabinet.

[0098] When the air outlet 11 of the air conditioner 100 needs to be closed, the driving member 31 drives the swing rod 32 to swing towards the air outlet 11, the swing rod 32 drives the driving bar 33 to move, and the guiding component 4 guides the driving bar 33 during the movement of the driving bar 33, so that the driving bar 33 drives the sliding door 2 to slide, and the sliding door 2 blocks the air outlet 11.

[0099] When the air outlet 11 of the air conditioner 100 needs to be opened, the driving member 31 drives the swing rod 32 to swing away from the air outlet 11, the swing rod 32 drives the driving bar 33 to move, and the guiding component 4 guides the driving bar 33 during the movement of the driving bar 33, so that the driving bar 33 drives the sliding door 2 to slide, and the sliding door 2 opens the air outlet 11.

[0100] Although the embodiments of the present disclosure have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present disclosure. Any changes, modifications, substitutions, and variations made by those of ordinary skill in the art to the above embodiments are within the protection scope of the present disclosure.
