The drive unit 11 drives the gear 121 to rotate, which drives the rack 122 to move, and drives the slider 2 through the rocker 123. The use of a rack and pinion transmission can make the movement of the slider 2 smoother.

[0043] In an exemplary embodiment of the present application, the driving portion 11 is a driving motor, and an output shaft of the driving motor is connected to the gear 121 .

[0044] Specifically, the drive box assembly 1 includes a first drive box 13 and a second drive box 14. The first drive box 13 is provided with a first guide groove 131, a first mounting position 132 and a rack slide groove 133; the second drive box 14 is provided with a second guide groove 141 and a second mounting position 142. The second guide groove 141 is arranged corresponding to the first guide groove 131. The second guide groove 141 and the first guide groove 131 jointly form a sliding track 100. The first mounting position 132 and the second mounting position 142 jointly form an installation space. The installation space is used to install at least one of the drive part 11 and the gear 121. The rack slide groove 133 is used for the rack 122 to be moved and set. By setting the rack slide groove 133, the movement guiding and anti-jumping effects of the rack 122 can be achieved, and the second guide groove 141 and the first guide groove 131 together form a sliding track 100, so that after the first drive box 13 and the second drive box 14 are assembled, the slider 2 is located between the first drive box 13 and the second drive box 14, and the slider 2 is guided by the first drive box 13 and the second drive box 14, and slides more smoothly, and the first drive box 13 and the second drive box 14 can limit and fix the slider 2 in multiple directions, while increasing the load-bearing capacity of the slider 2.

[0045] In an exemplary embodiment of the present application, there are two first guide grooves 131 and two second guide grooves 141, the profiles of the two first guide grooves 131 are both arc-shaped, the two second guide grooves 141 are set to the same value as the profiles of the corresponding first guide grooves 131, and the depth direction of the rack groove 133 is set along the height direction of the first drive box 13.

[0046] In combination with the above embodiments, the present application provides a preferred embodiment of a drive box assembly 1, such as Figure 7 and Figure 8 As shown, in this embodiment, a fourth rib 154 is provided on the rack 122, a third rib 153 is provided on the second drive box 14, and a first rib 151 and a second rib 152 are provided on the first drive box 13. The provision of the ribs makes the connection between the components more stable and less likely to fall off or shift due to movement.

[0047] Specifically, the slider 2 includes a slider body 21, each provided with a sliding pin 22 at each end. At least a portion of the sliding pin 22 is positioned within the slide track 100. The slider body 21 is provided with at least one positioning structure 23, through which the slider body 21 is connected to the sliding door 3. The slider body 21 is provided with at least one ball bearing hole 24, extending along the height of the slider body 21. A ball 20 is positioned within the ball bearing hole 24. As the slider body 21 moves along the slide track 100, the ball 20 rolls within the second guide groove 141. The provision of the ball bearing hole 24 allows the ball 20 to rotate 360° within the ball bearing hole 24. Compared to traditional slider movement methods, this provides greater flexibility, effectively reduces frictional resistance, and achieves smoother and more stable movement, effectively preventing jamming. This ensures the quality of the air conditioner product and enhances the user experience.

[0048] In combination with the above embodiment, both ends of the sliding pin 22 are respectively located in the corresponding first guide groove 131 and second guide groove 141, and the two sliding pins 22 located at both ends of the slider body 21 are respectively located in the two second guide grooves 141. Figure 9 and Figure 10 As shown, when both ends of the slider body 21 are inserted into the second guide groove 141 and the first guide groove 131 through the sliding pin 22 , a chamfered structure is provided to avoid wear.

[0049] Furthermore, the slider 2 includes a stop pin 25 disposed within the ball hole 24 and configured to limit the position of the ball 20. The stop pin 25 can limit the position of the ball 20, preventing the ball 20 from escaping from the ball hole 24 and affecting the movement of the slider 2. Preferably, the stop pin 25 is a latching pin.

[0050] Preferably, there are two ball holes 24. The provision of two ball holes 24 makes the sliding of the slider 2 smoother. In this embodiment, the balls 20 in the two ball holes 24 move in the same second guide groove 141. According to actual needs, the balls 20 in the two ball holes 24 can also move in two second guide grooves 141 respectively.

[0051] Furthermore, the positioning structure 23 includes a positioning pin 231 and a positioning hole 232. The positioning pin 231 is connected to the slider body 21 and extends along the width of the slider body 21. The positioning hole 232 extends along the width of the slider body 21. The positioning pin 231 and the positioning hole 232 are both located on the side of the slider body 21 away from the drive unit 11. The slider body 21 is connected to the sliding door 3 via the positioning pin 231 and the positioning hole 232. The provision of the positioning pin 231 and the positioning hole 232 facilitates the connection and removal of the sliding door 3 from the slider 2, facilitating subsequent maintenance of the air conditioner's interior.

[0052] Furthermore, a connecting pin hole 26 is provided on one side of the slider body 21 near the drive unit 11. The slider body 21 is connected to the rocker arm 123 via the connecting pin hole 26. The provision of the connecting pin hole 26 allows the rocker arm 123 to be connected to the slider body 21 via the latch 124, facilitating assembly and disassembly. It should be noted that the location of the connecting pin hole 26 can be adjusted based on actual needs. For example, in this embodiment, the connecting pin hole 26 is located at the same distance from the two sliding pins 22.

[0053] Furthermore, the slider body 21 includes a first body 211 and a second body 212, sliding pins 22 are provided at both ends of the first body 211, and a connecting pin hole 26 is provided on the side of the first body 211 close to the driving part 11; the second body 212 is connected to the side of the first body 211 away from the driving part 11, and a positioning structure 23 is provided on the side of the second body 212 away from the driving part 11; part of the hole wall of the ball hole 24 is opened on the first body 211, and part of the hole wall of the ball hole 24 is opened on the second body 212, and the height of the second body 212 is lower than the height of the first body 211.

[0054] In this embodiment, the first body 211 primarily moves along the slide rail 100, while the second body 212 primarily connects to the sliding door 3. In conjunction with the aforementioned embodiment, the second body 212 is lower than the first body 211, allowing the first body 211 to align with the first guide groove 131 and the second guide groove 141 in height. This allows the second body 212 to more closely match the height dimensions of the first drive box 13 and the second drive box 14, achieving a better assembly effect and reducing the space and volume of the entire sliding door drive device. It should be noted that in this embodiment, a baffle structure is provided on one side of the second body 212. This baffle structure effectively reduces dust intrusion and enhances the aesthetics of the connection between the sliding door 3 and the slider 2.

[0055] In the sliding door drive device in the above embodiment, the slider 2 adopts a "ball" type moving design, which has the characteristics of strong load-bearing capacity, low noise, and sensitive trajectory. Compared with the traditional "friction" or "roller" movement mode, the "ball" type slider has a stronger load-bearing capacity and effectively avoids the occurrence of being stuck due to excessive gravity. The "ball" type slider adopts point and surface contact mode, with a small contact area, which effectively reduces the generation of noise.

[0056] The assembly process of the sliding door drive device in the above embodiment is as follows: first, the drive motor is assembled on the second drive box 14, then the gear 121 is fixed to the output shaft of the drive motor, the toothed side of the rack 122 is meshed with the gear 121, the other side of the rack 122 is connected to the pin hole of the rocker 123 through the connecting hole and the latch 124, and the latch 124 at the other end of the rocker 123 is assembled with the connecting pin hole 26 of the slider 2, the ball 20 is assembled in the ball hole 24 of the slider 2, and the sliding pin on the slider 2 is fixed. One end of the sliding pin 22 cooperates with the second guide groove 141 on the second drive box 14, and then the first drive box 13 is covered on the second drive box 14. At this time, the other end of the sliding pin 22 cooperates with the first guide groove 131 of the first drive box 13, and the rack 122 is located in the rack slide groove 133 of the first drive box 13. Under the joint action of the first guide groove 131 of the first drive box 13 and the second guide groove 141 of the second drive box 14, the slider 2 slides along the sliding track 100 under the action of the ball 20.
