[0048] Figure 1 This is a schematic structural diagram of an air conditioner indoor unit according to an embodiment of the present invention, such as... Figure 1 As shown, and with reference Figures 2 to 7 This utility model provides a drive device 200 for an air conditioner, which includes a drive base 210, a first drive arm 220 and a compression roller 230.

[0049] A first slide groove 2101 is provided on the drive base 210. A first drive arm 220 is provided on the drive base 210 and has a sliding part 221 that inserts into the first slide groove 2101. A pressing roller 230 is rotatably provided on the drive base 210 and is provided on the upper side of the first drive arm 220 and is in contact with the first drive arm 220.

[0050] When the first drive arm 220 is in operation, the sliding part 221 of the first drive arm 220 moves along the first slide groove 2101 of the drive seat 210. The extrusion roller 230 located above the first drive arm 220 rotates synchronously with the movement of the first drive arm 220, continuously applying vertical pressure to the first drive arm 220 through rolling contact. The rotational action of the extrusion roller 230 cooperates with the limiting action of the first slide groove 2101 to constrain the movement trajectory of the first drive arm 220 and keep it in linear motion.

[0051] In this embodiment, the continuous vertical pressure exerted by the compression roller 230 on the first drive arm 220 prevents the sliding part 221 from being squeezed against the upper surface of the first slide groove 2101, thus ensuring that the sliding part 221 always moves in close contact with the lower surface within the first slide groove 2101. The compression action of the compression roller 230 directly constrains the vertical freedom of the first drive arm 220, preventing it from jumping or deviating due to mechanical clearance or external interference, thereby ensuring that the sliding part 221 of the first drive arm 220 moves smoothly along the first slide groove 2101. Compared with the prior art, this embodiment significantly improves the motion stability of the drive device 200, reduces jamming, and extends the service life of the drive device 200.

[0052] Furthermore, this embodiment can reduce the occurrence of jamming during operation of the driven components, which helps to reduce noise and improve the user's experience of using the air conditioner.

[0053] In some optional embodiments of this utility model, such as Figures 4 to 6 As shown, the drive device 200 also includes a gear 241 and a rack 242. The gear 241 is rotatably mounted on the drive base 210. The rack 242 is mounted on the first drive arm 220, and the gear 241 and the rack 242 mesh.

[0054] This embodiment further optimizes the motion control precision and driving force transmission efficiency of the first drive arm through the meshing transmission structure of gear 241 and rack 242. The rotational motion of gear 241 is directly converted into the linear displacement of the first drive arm through rack 242, and its meshing characteristics ensure that the stroke of the first drive arm 220 corresponds precisely to the rotation angle of gear 241. Combined with the pressing action of the pressing roller 230, the movement of the first drive arm 220 within the first slide groove 2101 is both actively guided by the meshing of gear 241 and eliminates mechanical backlash through the pressure of the pressing roller 230. This dual constraint significantly improves the anti-deviation capability and overall reliability under complex working conditions.

[0055] In some optional embodiments of this utility model, such as Figure 4 and Figure 6 As shown, the drive device 200 also includes a motor 243, the output shaft of which is connected to a gear 241 to drive the gear 241 to rotate, thereby driving the first drive arm 220 to move.

[0056] In some optional embodiments of this utility model, the gear 241 is disposed on the lower side of the rack 242.

[0057] In some optional embodiments of this utility model, the gear 241 is disposed on the upper side of the rack 242. The rack 242 is located on the upper side of the drive arm. Compared with the previous embodiment, in this embodiment, the gear 241 presses the rack 242 downward, which can further increase the effect of preventing the first drive arm 220 from jamming and can prevent the sliding part 221 from being pressed against the upper surface of the first sliding groove 2101.

[0058] In some optional embodiments of this utility model, such as Figure 4 and Figure 6 As shown, along the extending direction of the rack 242, the extrusion roller 230 is disposed on the side of the gear 241 opposite to the extended end of the first drive arm 220; the extrusion roller 230 is disposed adjacent to the gear 241.

[0059] In this embodiment, the extrusion roller 230 is positioned close to the gear 241, so that the constraint forces of the extrusion roller 230 and the gear 241 on the first drive arm 220 are applied to the same section, thereby enhancing the constraint effect on the first drive arm 220 in the vertical direction and improving the operational stability of the first drive arm 220.

[0060] In some optional embodiments of this utility model, such as Figure 4 As shown, the first drive arm 220 is provided with a first cavity wall 225 and a second cavity wall 226 arranged opposite to each other, and a rack cavity with an upward opening is formed between the first cavity wall 225 and the second cavity wall 226, and the rack 242 is disposed in the rack cavity; the upper ends of the first cavity wall 225 and the second cavity wall 226 are at the same height, and the peripheral wall of the extrusion roller 230 is always in contact with the upper ends of the first cavity wall 225 and the second cavity wall 226.

[0061] In this embodiment, the peripheral wall of the extrusion roller 230 is always in contact with the upper ends of the first cavity wall 225 and the second cavity wall 226. On the one hand, this allows the extrusion roller 230 to roll close to the top ends of the first cavity wall 225 and the second cavity wall 226 simultaneously, applying pressure evenly to the first cavity wall 225 and the second cavity wall 226, ensuring that the rack 242 is always centered and avoiding lateral offset or misalignment when meshing with the gear 241. On the other hand, this can distribute the pressure to the entire rack cavity structure, reducing the risk of local deformation of the rack 242 and improving transmission stability.

[0062] In some optional embodiments of this utility model, the first drive arm 220 is provided with an upward-facing extrusion surface, and the peripheral wall of the extrusion roller 230 is always in contact with the extrusion surface. Specifically, the rack 242 is disposed on the lower side of the first drive arm 220, and the gear 241 is located on the lower side of the rack 242; or, the rack 242 is disposed on the upper side of the first drive arm 220, and the gear 241 is disposed on the upper side of the rack 242, with the rack 242 arranged parallel to or spaced apart from the extrusion surface. In this embodiment, the peripheral wall of the extrusion roller 230 is always in contact with the extrusion surface, thereby ensuring that the sliding part 221 of the first drive arm always moves smoothly along the first slide groove 2101.

[0063] In some optional embodiments of this utility model, the sliding part 221 includes a plurality of protrusions extending from the side of the first drive arm 220, and each protrusion is fitted with a bushing; the bushing is made of POM material, and the extrusion roller 230 is made of POM material. POM (full name Polyoxymethylene) is a high-density, highly crystalline thermoplastic engineering plastic. Because its properties are close to those of metal, it is often called "metal among plastics" or "plastic steel".

[0064] This embodiment utilizes the self-lubricating and wear-resistant properties of POM material to significantly reduce the friction between the sliding part 221 and the first groove 2101. The bushing and the extrusion roller 230 are made of POM material, which can not only buffer vibration and reduce noise, but also avoid jamming or wear caused by direct friction between metals, thus improving the smoothness and durability of the drive device 200, and is especially suitable for high-frequency reciprocating motion scenarios.

[0065] In some optional embodiments of this utility model, there is one first slide groove 2101, which is disposed on one side of the first drive arm 220.

[0066] In some optional embodiments of this utility model, such as Figure 6 As shown, there are two first sliding grooves 2101, which are respectively set on both sides of the first drive arm 220; and multiple protrusions are set on both sides of the first drive arm 220, and each protrusion is equipped with a bushing.

[0067] In this embodiment, by symmetrically arranging two first sliding grooves 2101 on both sides of the first drive arm 220, the force on both sides of the first drive arm 220 is more balanced during movement, avoiding skewing or jamming caused by uneven force on one side of the first sliding groove 2101. The multiple protrusions on both sides and their POM bushings further disperse the motion pressure and reduce the frictional loss of the contact surface of the first sliding groove 2101.

[0068] In some optional embodiments of this utility model, such as Figures 4 to 6As shown, the drive device 200 further includes a second drive arm 250, on which a first cylinder 251 and a second cylinder 252 are coaxially arranged. The drive base 210 is also provided with a second sliding groove 2102, and the first drive arm 220 is provided with a third sliding groove 223. The first cylinder 251 is inserted into the second sliding groove 2102, and the second cylinder 252 is inserted into the third sliding groove 223. The extended ends of the first drive arm 220 and the second drive arm 250 are spaced apart and rotatably connected to the driven component. The first cylinder 251 can slide within the second sliding groove 2102, and the second cylinder 252 can slide within the third sliding groove 223.

[0069] In this embodiment, when the first drive arm 220 slides along the first slide groove 2101 in the first direction, under the combined action of the second slide groove 2102, the first cylinder 251, the third slide groove 223, and the second cylinder 252, the second drive arm 250 slides relative to the first drive arm 220 at least in the second direction. The first direction is opposite to the second direction. Similarly, when the first drive arm 220 slides along the first slide groove 2101 in the second direction, the second drive arm 250 slides relative to the first drive arm 220 at least in the first direction.

[0070] For example, the first direction is forward, the second direction is backward, the air outlet 120 is located on the front side of the indoor unit 100, and the driven component is the air guide plate 140. When the air guide plate 140 closes the air outlet 120, the extended end of the first drive arm 220 is located below the extended end of the second drive arm 250. When the extended end of the first drive arm 220 pushes the air guide plate 140 forward, the extended end of the second drive arm 250 pulls the air guide plate 140 backward, causing the air guide plate 140 to rotate and open the air outlet 120; when the extended end of the first drive arm 220 pulls the air guide plate 140 backward, the extended end of the second drive arm 250 pushes the air guide plate 140 forward to close the air outlet 120.

[0071] Compared to embodiments that only have a first drive arm 220, this embodiment adds a second drive arm 250, making the movement of the driven component more stable and the driving force greater. The dual drive arms can transform the linear motion of the first drive arm 220 into a larger rotation angle or a more complex motion trajectory of the driven component.

[0072] In some optional embodiments of this utility model, such as Figures 4 to 7 As shown, the first drive arm 220 is also provided with a fourth slide groove 224 to prevent movement jamming, and the second drive arm 250 is provided with a third cylinder 253, which is parallel to the first cylinder 251 and is inserted into the fourth slide groove 224. Specifically, the third cylinder 253 can slide within the fourth slide groove 224.

[0073] When the drive device 200 is in a dead position, its first drive arm 220 and second drive arm 250 will temporarily lose their definite direction of movement, causing the drive device 200 to be unable to continue moving as expected. The dead point is also called the stop point or a special position of the drive device 200. Therefore, this embodiment, by setting a fourth slide groove 224 and a third cylinder 253, can prevent the first drive arm 220, second drive arm 250, second cylinder 252, and third slide groove 223 from entering the dead position during movement, thereby improving the operational stability of the drive device 200.

[0074] In some optional embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the extended ends of the first drive arm 220 and the second drive arm 250 are connected to the driven component via a connecting portion 150. One end of the connecting portion 150 is connected to the inner wall of the driven component. The connecting portion 150 is provided with a first mounting portion 151 and a second mounting portion 152. The extended end of the first drive arm 220 is rotatably connected to the first mounting portion 151, and the extended end of the second drive arm 250 is rotatably connected to the second mounting portion 152. The first mounting portion 151 and the second mounting portion 152 can be spaced apart along the width direction of the driven component. For example, when the driven component is an air guide plate 140, and the air guide plate 140 is installed at the air outlet 120, and the air outlet 120 is located at the front of the indoor unit 100 of the air conditioner, the connecting portion 150 can be located above the air guide plate 140, and the first mounting portion 151 can be located below the second mounting portion 152.

[0075] In some optional embodiments of this utility model, such as Figure 6 As shown, the drive base 210 has a box-like structure and includes a first part 211 and a second part 212. Both the first part 211 and the second part 212 are provided with a first sliding groove 2101. The gear 241, the first drive arm 220, the second drive arm 250, and the pressing roller 230 are all disposed inside the drive base 210. This box-like structure of the drive base 210 has a dustproof function.

[0076] In some optional embodiments of this utility model, such as Figure 3 As shown, two drive devices 200 are connected to the air guide plate 140, and the two drive devices 200 are spaced apart along the length direction of the air guide plate 140. Furthermore, the two drive devices 200 are located on both sides of the length direction of the air outlet 120. By setting two drive devices 200, the operational stability of the air guide plate 140 can be further improved.

[0077] An embodiment of this utility model also provides an air conditioner indoor unit 100, such as... Figures 1 to 2As shown, the air conditioner indoor unit 100 includes a body 110 and a drive device 200 as described in any of the above embodiments, with a drive base 210 disposed on the body 110.

[0078] In this embodiment, the indoor unit 100 of the air conditioner includes a driven component, which can be a damper structure such as an air guide plate 140 or a panel, and can be installed at the air outlet 120 or the air inlet 130. Since the driving device 200 in this embodiment has good operational stability, the driven component can operate smoothly, thereby reducing the noise of the indoor unit 100 of the air conditioner and improving the user experience.

[0079] In some optional embodiments of this utility model, such as Figures 2 to 5 As shown, the indoor unit 100 of the air conditioner also includes an air guide plate 140. An air outlet 120 is formed on the body 110; the air guide plate 140 is installed at the air outlet 120 and is used to open or close the air outlet 120. The front end of the first drive arm 220 of the drive device 200 is rotatably connected to the air guide plate 140. The first drive arm 220 moves in the inward and outward directions along the body 110, and the drive device 200 is configured to drive the air guide plate 140 to open or close the air outlet 120. An air inlet 130 is also formed on the body 110. The air inlet 130 and the air outlet 120 are located on the front side of the body 110, and the air inlet 130 is located above the air outlet 120. Specifically, the body 110 includes a front shell 111 and a rear shell with an outward opening. The front shell 111 is located at the front opening of the rear shell, and the front shell 111 and the rear shell are detachably connected. The air outlet 120 and the air inlet 130 are both located on the front shell 111.

[0080] In this embodiment, the drive device 200 can smoothly drive the air guide plate 140 to open or close the air outlet 120. Both the air inlet 130 and the air outlet 120 are located on the front side of the unit 110, which facilitates the embedded installation of the indoor unit in a cabinet or wall to meet the diverse usage needs of users.

[0081] In some embodiments of this utility model, the air conditioner indoor unit 100 is a recessed air conditioner indoor unit, a wall-mounted air conditioner indoor unit, a floor-standing air conditioner indoor unit, or other types of air conditioner indoor units.
