Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a sliding plate drive assembly for an air conditioner and an indoor unit of an air conditioner. Background Technology

[0002] Currently, air conditioners typically have a sliding plate at the air outlet, using a rack and pinion structure to achieve its reciprocating motion, opening or closing the outlet. However, when the rack slides to its limit, a rigid collision easily occurs between the rack end and the inner wall of the drive housing, leading to problems such as high operating noise and accelerated wear on the rack and drive housing. Furthermore, frequent collisions can affect the smoothness of the sliding plate's movement, reducing the user experience. Utility Model Content

[0003] In view of the above problems, this utility model is proposed to provide a skateboard drive assembly and an air conditioner indoor unit that overcome or at least partially solve the above problems.

[0057] Figure 1This 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 with reference Figures 2 to 8 This utility model provides a slide plate drive assembly 10 for an air conditioner, which includes a drive box 11, a rack 12, a first anti-collision block 13, and a second anti-collision block 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 slide plate 30 to allow the slide plate 30 to move. The first anti-collision block 13 is disposed at one end of the rack 12, and the second anti-collision block 14 is disposed at the other end of the rack 12.

[0058] In some optional embodiments of this utility model, the first anti-collision block 13 is disposed at one end of the slide 110, and the second anti-collision block 14 is disposed at the other end of the rack 12.

[0059] In some optional embodiments of this utility model, the first anti-collision block 13 is disposed at one end of the rack 12, and the second anti-collision block 14 is disposed at the other end of the slide 110.

[0060] like Figure 4 and Figure 5 As shown, in some optional embodiments of this utility model, the first anti-collision block 13 is disposed at one end of the slide 110, and the second anti-collision block 14 is disposed at the other end of the slide 110.

[0061] In the above embodiments, the rack 12 reciprocates along the slide rail 110 inside the drive box 11, and the rack 12 drives the connected slide plate 30 to move synchronously to adjust the opening and closing of the air outlet. When the rack 12 slides to the limit position at one end of the slide rail 110, the first anti-collision block 13 is compressed and deformed to buffer the impact force of the collision; when the rack 12 slides in the opposite direction to the limit position at the other end, the second anti-collision block 14 absorbs the impact energy in the same way; when the rack 12 separates from the limit position of the slide rail 110, the first anti-collision block 13 or the second anti-collision block 14 resets. Therefore, during the operation of the rack 12, direct rigid collision between the rack 12 and the drive box 11 can be avoided, thereby realizing the smooth reciprocating movement of the slide plate 30.

[0062] In the above embodiments, first anti-collision blocks 13 and second anti-collision blocks 14 are respectively provided at both ends of the rack 12 or at both ends of the slide rail 110. When the rack 12 slides to its travel limit, the first anti-collision block 13 or the second anti-collision block 14 absorbs the impact energy through elastic deformation, avoiding direct rigid collision between the rack 12 and the inner wall of the drive box 11, significantly reducing the operating noise of the skateboard drive assembly 10 and reducing the wear of the rack 12 and the drive box 11. On the other hand, the buffering mechanism makes the skateboard 30 move more smoothly, avoiding jamming or vibration caused by collision, thereby improving user comfort and extending the service life of the skateboard drive assembly 10. In addition, the first anti-collision block 13 and the second anti-collision block 14 have simple structures and low cost, and can achieve reliable protection without complex sensors or control algorithms, which has high practicality and economy.

[0063] like Figure 4 and Figure 7 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 inside the box body 111. Slots 113 are provided on the end walls at both ends of the slide rail 110; a first anti-collision block 13 and a second anti-collision block 14 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.

[0064] In this embodiment, the first anti-collision block 13 and the second anti-collision block 14 are independently installed in the slots 113 on the end wall of the slide rail 110 and extend into the slide rail 110. The slot-type fixing method makes the anti-collision blocks form a detachable modular structure, which is convenient for individual replacement and maintenance without disassembling the rack 12 or the slide plate 30, thus reducing maintenance costs. In addition, the slot installation also ensures stable and non-displaced buffering effect, guarantees the buffer contact area, and precisely controls the buffer gap between the rack 12 and the end wall, avoiding positioning displacement of the slide plate 30 due to excessive deformation of the anti-collision block, further improving the durability and motion stability of the drive component.

[0065] like Figure 5 and Figure 7 As shown, in some optional embodiments of this utility model, the slot 113 includes a groove and an opening, the opening connecting the groove and the slide 110, and the width of the opening is smaller than the width of the groove. Both the first anti-collision block 13 and the second anti-collision block 14 include a base and an abutment portion. The base extends along the length of the slot 113 and is disposed within the groove. The abutment portion is disposed on the base and extends into the slide 110 through the opening. Specifically, the first anti-collision block 13 includes a first base and a first abutment portion, and the second anti-collision block 14 includes a second base 141 and a second abutment portion 142.

[0066] In this embodiment, the width of the opening is smaller than the width of the groove, forming a self-locking effect, which prevents the first anti-collision block 13 and the second anti-collision block 14 from coming out when impacted, thus ensuring the impact resistance stability of the first anti-collision block 13 and the second anti-collision block 14.

[0067] like Figure 7 As shown, in some optional embodiments of this utility model, the slot 113 is a T-slot or a dovetail slot. The T-slot or dovetail slot restricts the first anti-collision block 13 and the second anti-collision block 14 to be inserted only in a specific direction, avoiding installation errors. At the same time, the abutment part extends into the slide rail 110 through the narrow opening, ensuring that the buffer action point is accurately aligned with the movement path of the rack 12. The T-slot or dovetail slot is a universal mechanical connection structure with mature processing technology, reducing production costs. It is also easy to adapt to anti-collision blocks of different materials (such as rubber and silicone), meeting diverse needs.

[0068] like Figure 7 As shown, in some optional embodiments of this utility model, 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 box 111 penetrates the box 111. That is, the opening end of the box 111 is provided with a mounting port 114, which communicates with the slot 113. The bases of the first anti-collision block 13 and the second anti-collision block 14 are vertically inserted into the slot 113 through the mounting port 114, and the abutment portion extends into the slide rail 110 through the opening, thereby achieving a buffering effect and quick replacement.

[0069] In this embodiment, the above-described configuration allows the anti-collision block to be directly inserted or removed from the outside of the housing 111, improving assembly and maintenance efficiency. Specifically, it eliminates the need to disassemble internal components of the housing 111 (such as the rack 12 or the slide plate 30), achieving "disassembly-free maintenance" and greatly reducing maintenance difficulty and time consumption.

[0070] like Figures 1 to 8 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.

[0071] 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 frictional noise between the slide plate 30 and the inner wall of the air outlet. 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.

[0072] like Figure 3 and Figure 6 As 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] like Figure 3 and Figure 7As 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.

[0077] like Figure 3 , Figure 4 , Figure 6 and Figure 7 As 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.

[0078] 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.

[0079] like Figure 1 and Figure 4As 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.

[0080] 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.

[0081] like Figure 4 and Figure 6 As 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.

[0082] 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.

[0083] 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.

[0084] In some optional embodiments of this utility model, both the first anti-collision block 13 and the second anti-collision block 14 are made of rubber. Rubber has low raw material costs. In addition, rubber has a low dynamic elastic modulus, which allows it to produce greater deformation under stress, giving it a strong energy absorption capacity, making it suitable for high-frequency vibration or impact buffering scenarios.

[0085] In some optional embodiments of this utility model, the first anti-collision block 13 and the second anti-collision block 14 are both made of polyurethane. Polyurethane has excellent wear resistance, which is 3 to 5 times that of rubber.

[0086] like Figure 9 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.

[0087] 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.

[0088] In some optional embodiments of this utility model, when the drive motor 18 drives the rack 12 to slide within the drive box 11 via gears, the rack 12 drives the slide plate 30 to move laterally along the air outlet via the connector 17, thereby adjusting the opening and closing of the air outlet. The anti-collision block of the slide plate drive assembly 10 buffers the collision at the end of the rack 12's stroke. The double guide groove and the convex post cooperate to ensure the linear movement of the rack 12. The roller 16 supports and reduces friction, resulting in low operating noise and high positioning accuracy for the slide plate 30. At the same time, the modular drive box 11 can be quickly installed via the support frame. During maintenance, only the connector 17 needs to be disassembled to replace worn parts. The overall structure is compact and suitable for the small space of the air conditioner, with low energy consumption and long service life.

[0089] 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.
