[0051] Figure 1 This is a schematic structural diagram of a skateboard drive assembly 10 according to an embodiment of the present invention, as shown below. Figure 1 As shown, and refer to Figures 2 to 6This utility model provides a sliding plate drive assembly 10 for an air conditioner, which includes a drive box 11, a rack 12, a first buffer structure, and a second buffer structure 14. A slide rail 110 is defined within the drive box 11. The rack 12 is slidably mounted within the slide rail 110. The rack 12 is configured to connect with a sliding plate 30 to allow the sliding plate 30 to move. The first buffer structure includes a first magnetic body disposed at one end of the rack 12 and a second magnetic body correspondingly disposed at one end of the slide rail 110, with the first and second magnetic bodies having the same poles and facing each other. The second buffer structure 14 includes a third magnetic body 141 disposed at the other end of the rack 12 and a fourth magnetic body 142 correspondingly disposed at the other end of the slide rail 110, with the third and fourth magnetic bodies having the same poles and facing each other.

[0052] In this embodiment, the rack 12 reciprocates along the slide rail 110 within the drive box 11, driving the connected slide plate 30 to move synchronously to adjust the opening and closing of the air outlet. When the rack 12 slides close to one end of the slide rail 110, the first and second magnetic bodies of the first buffer structure approach each other, generating a repulsive force to buffer the impact of the collision; when the rack 12 slides in the opposite direction to the other end, the third and fourth magnetic bodies 141 and 142 of the second buffer structure 14 achieve buffering in the same way. Therefore, during the operation of the rack 12, direct rigid collision between the rack 12 and the drive box 11 can be avoided, thereby achieving smooth reciprocating movement of the slide plate 30.

[0053] In this embodiment, magnetic bodies with the same polarity facing each other are respectively set at both ends of the rack 12 and the corresponding ends of the slide rail 110 to form a non-contact magnetic buffer structure. When the rack 12 slides to its travel limit, the non-contact buffer significantly reduces operating noise and wear between the rack 12 and the drive box 11; secondly, the movement of the slide plate 30 is more stable, avoiding jamming and vibration, improving the user experience and the service life of the slide plate drive component 10; in addition, this buffer structure is simple, reliable, low-cost and easy to manufacture.

[0054] In some optional embodiments of this utility model, the first magnetic body and the third magnetic body 141 have the same magnetic force; the second magnetic body and the fourth magnetic body 142 have the same magnetic force.

[0055] Specifically, the magnetic force of each pair of magnetic bodies can be made the same by selecting magnetic bodies of the same material and specifications. In this embodiment, by making the magnetic forces of the first and third magnetic bodies at both ends of the rack 12 consistent, and the magnetic forces of the second and fourth magnetic bodies 142 at both ends of the slide rail 110 consistent, it is ensured that the magnetic repulsion buffering effect at both ends of the rack 12 during reciprocating motion is completely symmetrical. This effectively avoids motion jamming or uneven wear caused by uneven buffering force, thereby improving the smoothness and consistency of the slide plate 30's movement and extending the service life of the components.

[0056] In some optional embodiments of this utility model, the first magnetic body and the third magnetic body 141 are respectively protruding from the end walls at both ends of the rack 12. In this embodiment, the magnetic bodies can be directly fixed to the end faces of the rack 12 by means of bonding or mechanical snap-fit, which helps to reduce production costs and improve assembly efficiency. Through the above arrangement, the magnetic bodies at both ends of the rack 12 can approach the corresponding magnetic bodies on the end walls of the slide rail 110 to the maximum extent. This layout effectively reduces the initial interaction distance between the magnetic poles, allowing the magnetic repulsion force to take effect earlier and more significantly, thereby optimizing the smoothness of the buffering process and improving the buffering effect.

[0057] In some optional embodiments of this utility model, the rack 12 has mounting grooves at both ends; the first magnetic body and the third magnetic body 141 are respectively embedded in the corresponding mounting grooves, and at least part of them extend into the slide rail 110. With the above arrangement, the first magnetic body and the third magnetic body 141 can be securely embedded in the rack 12 body, avoiding accidental collisions or falling off due to protrusion.

[0058] In some optional embodiments of this utility model, the orthographic projection of the first magnetic body onto the second magnetic body is located within the outer contour of the second magnetic body, and the orthographic projection of the third magnetic body 141 onto the fourth magnetic body 142 is also located within the outer contour of the fourth magnetic body 142. This arrangement ensures precise alignment of the relative magnetic bodies during operation, resulting in a stable and unbiased magnetic force direction. This effectively improves the smoothness and reliability of the buffering process, avoids abnormal wear or jamming of the rack 12 due to uneven force distribution, and thus guarantees the long-term operational stability of the entire skateboard drive assembly 10.

[0059] In some optional embodiments of this utility model, the second magnetic body and the fourth magnetic body 142 are both protruding on the inner wall of the slide, which simplifies the installation process and reduces the processing and assembly costs while ensuring a good buffering effect.

[0060] like Figure 3 and Figure 5 As shown, in some optional embodiments of this utility model, the drive box 11 includes a box body 111, and a slide rail 110 is disposed within the box body 111. Slots 113 are provided on the end walls at both ends of the slide rail 110; the second magnetic body and the fourth magnetic body 142 are respectively installed in the two slots 113 and extend into the slide rail 110 to prevent the rack 12 from contacting the end walls of the slide rail 110. This slot structure provides precise positioning and stable support for the magnetic bodies, simplifying the assembly process.

[0061] like Figure 3 and Figure 5As shown, in some optional embodiments of this utility model, the slot 113 is a T-shaped slot or a dovetail slot. The slot 113 includes a groove and an opening, the opening connecting the groove and the slide rail 110, and the width of the opening is smaller than the width of the groove. Both the second magnetic body and the fourth magnetic body 142 include a base and an active part. The base extends along the length direction of the slot 113 and is disposed within the groove. The active part is disposed on the base and extends into the slide rail 110 through the opening. The slot 113 extends in a direction perpendicular to the slide rail 110, and one end of the slot 113 adjacent to the opening of the housing 111 penetrates the housing 111. That is, the opening end of the housing 111 is provided with a mounting port 114, which communicates with the slot 113.

[0062] In this embodiment, the second and fourth magnetic bodies 142 are aligned and slid into the corresponding T-shaped or dovetail-shaped slots along the mounting port 114 at the opening end of the housing 111. This T-shaped or dovetail-shaped slot structure enables quick insertion and self-locking of the magnetic bodies, with the base confined within the slot and unable to come out of the opening, ensuring a firm and reliable connection.

[0063] like Figure 1 , Figure 5 and Figure 6 As shown, in some optional embodiments of this utility model, the drive box 11 further includes a cover 112, which is disposed at the opening of the box body 111. A first guide groove 115 is provided on the bottom wall of the slide 110, and a second guide groove 116 is provided on the cover 112 opposite to the first guide groove 115. A first protrusion 121 is provided on one side of the rack 12, which is inserted into the first guide groove 115, and a second protrusion 122 is provided on the other side of the rack 12, which is inserted into the second guide groove 116.

[0064] In this embodiment, after the cover 112 closes the opening of the box body 111, when the rack 12 reciprocates along the slide rail 110, the first protrusion 121 slides linearly within the first guide groove 115, and the second protrusion 122 slides linearly within the second guide groove 116. The cooperation of the first protrusion 121 and the first guide groove 115, as well as the cooperation of the second protrusion 122 and the second guide groove 116, forms a double guiding constraint, limiting the rack 12 from deviating in the direction perpendicular to the slide rail 110, ensuring the precise movement trajectory of the rack 12, enabling the slide plate 30 to achieve smooth linear movement, reducing abnormal wear between the rack 12 and the side wall of the slide rail 110, thereby reducing operating noise. In addition, the sealing structure of the cover 112 can also prevent dust from entering the slide rail 110, protecting the internal transmission components. Therefore, this embodiment improves the reliability, durability, and user experience of the air conditioner's air outlet control.

[0065] like Figure 4 , Figure 5 and Figure 6As shown, in some optional embodiments of this utility model, the first protruding post 121 includes a first base post and a first insertion post. The first base post is connected to the rack 12 and contacts the bottom wall of the slide 110. The first insertion post is coaxially arranged with the first base post, and is disposed on the first base post, inserting into the first guide groove 115. The top wall of the slide 110 is on the cover 112, and the second guide groove 116 is disposed on the top wall of the slide 110. The second protruding post 122 includes a second base post 1221 and a second insertion post 1222. The second base post 1221 is connected to the rack 12 and contacts the top wall of the slide 110; the second insertion post 1222 is coaxially arranged with the second base post 1221, and is disposed on the second base post 1221, inserting into the second guide groove 116.

[0066] In this embodiment, the first base post and the second base post 1221 on the upper and lower sides of the rack 12 are in contact with the bottom wall and the top wall of the slide 110, respectively. The first insertion post is embedded in the first guide groove 115 and the second insertion post 1222 is embedded in the second guide groove 116, forming a three-dimensional guide, which is beneficial to further suppress the rack 12 sway and ensure the smoothness of the slide 30.

[0067] In some optional embodiments of this utility model, the bottom of the rack 12 and the bottom wall of the slide 110 are in surface contact.

[0068] In some optional embodiments of this utility model, the opening of the box 111 faces upward. A support rib 117 extending in a direction parallel to the slide 110 is also provided on the bottom wall of the slide 110. The rack 12 contacts the support rib 117.

[0069] like Figure 2 and Figure 5 As shown, in this embodiment, the supporting ribs 117 on the bottom wall of the slide rail 110 extend along the movement direction of the rack 12. When the rack 12 is driven to slide back and forth, its bottom surface maintains line contact with the supporting ribs 117. Through this line contact, the supporting ribs 117 significantly reduce sliding friction, ensuring smooth and stable movement of the rack 12 and the slide plate 30. Compared to the full-plane contact between the bottom wall of the slide rail 110 and the bottom of the rack 12, this embodiment, by setting the supporting ribs 117, can significantly reduce the contact area between the rack 12 and the slide rail 110, significantly reduce sliding friction resistance, improve transmission efficiency, and reduce energy consumption, ensuring smooth and stable movement of the rack 12 and the slide plate 30. Furthermore, this embodiment can also reduce friction noise and wear particle generation, making the air conditioner operate more quietly and extending the maintenance cycle, comprehensively improving the product's reliability, energy efficiency, and user experience.

[0070] like Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, in some optional embodiments of this utility model, the box 111 is further provided with a roller space 118 and a gear space 119 communicating with the slide rail 110. The skateboard drive assembly 10 also includes a drive gear 15 and a roller 16. The drive gear 15 is disposed on one side of the rack 12, located in the gear space 119, and meshes with the rack 12; the roller 16 is disposed on the other side of the rack 12, located in the roller space 118, the axis of the roller 16 is horizontally arranged, and the roller 16 contacts the bottom wall of the roller space 118. Specifically, a first mounting post 124 is provided on the other side of the rack 12, and the roller 16 is rotatably mounted on the first mounting post 124. The roller 16 is configured to slide along the bottom wall of the slide rail 110.

[0071] In this embodiment, the drive gear 15 meshes with the rack 12 within the gear space 119, converting torque into linear motion of the rack 12 through rotational motion. Simultaneously, the roller 16 on the other side of the rack 12 rotates freely on the first mounting post 124, maintaining rolling contact with the bottom wall of the roller space 118. As the rack 12 reciprocates along the slide rail 110, the roller 16 both supports the weight of the rack 12 and guides its direction of movement, enabling the slide plate 30 to achieve low-resistance, high-stability, and low-noise opening and closing actions, thereby driving the slide plate 30 to precisely adjust the opening and closing of the air outlet. Furthermore, the drive gear 15 and the roller 16 act on both sides of the rack 12 respectively, ensuring even force distribution on the rack 12 and preventing deformation failure caused by unilateral wear, thus extending the component's lifespan.

[0072] like Figure 1 , Figure 2 and Figure 7 As shown, in some optional embodiments of the present invention, the skateboard drive assembly 10 further includes a connector 17, which is connected to the rack 12 and extends from the side of the drive box 11. The connector 17 is configured to connect to the skateboard 30. The connector 17 is disposed on the upper side of the roller 16.

[0073] Specifically, one end of the connector 17 is fixed to the upper end of the rack 12 and extends outward through a pre-drilled hole in the side wall of the drive box 11, while the other end of the connector 17 is connected to the slide plate 30. The connector 17 is used to synchronously transmit the linear motion of the rack 12 to the slide plate 30. The connector 17 is located above the roller 16, and its installation height avoids the rolling trajectory of the roller 16 and the meshing area of ​​the drive gear 15, ensuring that the connector 17 drives the slide plate 30 to move without interference when the rack 12 slides.

[0074] like Figure 2 and Figure 4As shown, in some optional embodiments of this utility model, the upper part of the rack 12 is provided with at least two second mounting posts 123, each of which is vertically arranged in the up-down direction. The connector 17 is provided with at least two mounting holes, which are correspondingly arranged with the second mounting posts 123, and the second mounting posts 123 are inserted into the mounting holes. During assembly, the connector 17 only needs to be sleeved onto the second mounting posts 123 through the mounting holes, which is a simple and easy assembly method. The above assembly method enables a detachable connection between the connector 17 and the rack 12, thereby facilitating the replacement or maintenance of the connector 17.

[0075] like Figure 1 As shown, in some optional embodiments of this utility model, the skateboard drive assembly 10 further includes a drive motor 18. The drive motor 18 is disposed on the outside of the cover 112, and the output shaft of the drive motor 18 is connected to the drive gear 15 to drive the drive gear 15 to rotate.

[0076] Specifically, the drive motor 18 is fixed to the outside of the cover 112, and its output shaft extends through the cover 112 into the gear space 119, where it is coaxially connected with the drive gear 15. When the drive motor 18 is powered on, the output shaft drives the gear 15 to rotate, and the gear meshes with the rack 12 to generate a lateral force, pushing the rack 12 to move linearly along the slide rail 110. The rack 12 is fixedly connected to the slide plate 30 through the connector 17, so the reciprocating movement of the rack 12 directly drives the slide plate 30 to open and close synchronously. During this process, the roller 16 on the other side of the rack 12 always maintains rolling contact with the bottom wall of the slide rail 110, supporting the weight of the rack 12 and ensuring stable movement direction, ultimately achieving precise and low-resistance linear movement of the slide plate 30 under the control of the drive motor 18.

[0077] In some optional embodiments of this utility model, the first magnetic body, the second magnetic body, the third magnetic body 141, and the fourth magnetic body 142 are all permanent magnets, such as neodymium iron boron magnets or ferrite magnets. This embodiment utilizes the inherent stable magnetic field of permanent magnets to continuously generate the required buffer repulsive force without external power supply, making the entire buffer structure simple, reliable, and maintenance-free.

[0078] like Figure 7 As shown, an embodiment of this utility model also provides an indoor unit 1 for an air conditioner, which includes a housing 20, a sliding plate 30, and a sliding plate drive assembly 10 as described in any of the above embodiments. The housing 20 has an air outlet 201, and a support frame is disposed inside the housing 20. The sliding plate 30 is slidably disposed at the air outlet 201 to open or close the air outlet. The drive box 11 of the sliding plate drive assembly 10 is fixed to the support frame, and a rack 12 is connected to the sliding plate 30. The support frame can also be referred to as a skeleton, and the evaporator, fan, etc., can be mounted on the support frame.

[0079] In this embodiment, since the sliding plate drive assembly 10 has the advantages of low motion noise and smooth operation, the sliding plate 30 can be driven by the sliding plate drive assembly 10 to open or close the air outlet smoothly and accurately, thereby improving the quietness of the air conditioner indoor unit and improving the overall user experience.

[0080] In some optional embodiments of this utility model, when the drive motor 18 drives the rack 12 to slide in the drive box 11 through the gear, the rack 12 drives the slide plate 30 to move laterally along the air outlet through the connector 17, thereby realizing the opening and closing adjustment of the air outlet.

[0081] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
