By designing a slider 4, instead of the conventional gear-rack transmission, the slider 4 is driven by the motor 3 to move back and forth in the driving box 1, directly driving the sliding door 21 to move back and forth, simplifying the entire driving mechanism 22, reducing the number of assembly parts, thereby reducing the space occupancy rate, and at the same time improving the assembly efficiency of the sliding door 21 driving mechanism 22, facilitating subsequent air-conditioning maintenance, and the motor 3 directly transmits force to the slider 4, reducing the transmission process from the gear to the rack. The force transmission is motor 3-slider 4-sliding door 21, rather than the conventional motor 3-gear-slider 4 (or rack)-sliding door 21, avoiding movement abnormalities caused by tooth profile accuracy, meshing virtual position, etc., making the mechanism more stable and reliable.

[0042] like Figure 5 As shown, in order to save costs, in this embodiment, the drive box 1 is a fan-shaped structure, and the motor 3 is arranged on one side of the central angle of the drive box 1; the slider 4 is a fan-shaped structure, and one end of the central angle is connected to the motor 3.

[0043] Driven by the motor 3 , the slider 4 swings along the circumferential direction of the driving box 1 , thereby driving the sliding door 21 to move back and forth to open or close the air outlet.

[0044] It should be noted that in order to ensure that the moving distance can achieve the effect of driving the sliding door 21 to open and close the air outlet, the specifications of the slider 4 and the specifications of the drive box 1 should be pre-designed to ensure that the slider 4 can drive the sliding door 21 to fully open and close the air outlet when moving back and forth.

[0045] like Figure 3 and Figure 4 As shown, in order to facilitate the sliding of the roller 5, ensure the rolling effect, and play the role of limiting the motion trajectory, in this embodiment, at least two arc-shaped roller grooves 6 are provided in the drive box 1 and the drive box cover 2 along the circumferential direction, all the roller grooves 6 are arranged in parallel and spaced apart, and the centers of all the roller grooves 6 coincide with the rotation center of the slider 4; the roller 5 is slidably arranged in the roller groove 6.

[0046] like Figure 5 As shown, it should be noted that, in this embodiment, there are two roller slots 6 , and there are two rollers 5 in each roller slot 6 , so a total of four rollers 5 are designed on the slider 4 .

[0047] Of course, the number of roller chutes 6 and the number of rollers 5 are not limited thereto, and may also be set to other numbers, which are not specifically limited in the present invention.

[0048] The roller 5 on the sliding block 4 moves back and forth in the double sliding groove, directly drives the sliding door 21, solves the problems of complex transmission mechanism and high precision requirement, multiple rollers 5 share the stress, ensures that the sliding block 4 can keep horizontal state at all times during operation, avoids the problems of abnormal stress, abnormal sound, jam and the like caused by the inclination of the sliding block 4, and the motor 3 directly transmits force to the sliding block 4 instead of the conventional motor 3-gear-sliding block 4 (or rack) transmission mode, reduces the virtual position between transmission parts, simplifies the structure, and is more stable and reliable.

[0049] As shown in Figure 5 and Figure 6 , in order to fix the roller 5 and ensure the rotation of the roller 5, the fixed groove 7 is arranged on the sliding block 4 in the embodiment, and the roller 5 is rotatably arranged in the fixed groove 7.

[0050] Further, as shown in Figure 6 , recesses 11 for supporting the rotating shaft are arranged on the opposite two side walls in the fixed groove 7, and the top of the recess 11 is provided with a reverse buckle structure 12.

[0051] The reverse buckle structure 12 makes the rotating shaft of the roller 5 not come out of the recess 11, which not only facilitates the penetration of the rotating shaft, but also has a certain anti-extraction effect.

[0052] As shown in Figures 1-4 , considering that the sliding door 21 needs to be connected with the sliding block 4, in order to facilitate the penetration of the sliding block 4, the arc-shaped sides of the driving box 1 and the driving box cover 2 are respectively provided with notches 8, and the two notches 8 enclose a through window 9 for the end of the sliding block 4 to pass through.

[0053] As shown in Figure 3 and Figure 4 , as a further improvement of the utility model, the roller sliding grooves 6 near the driving box 1 are respectively provided with limiting ribs 10 at two ends, and the top of the limiting rib 10 is higher than the top edge of the roller sliding groove 6, so as to form a limiting step.

[0054] As a further improvement of the utility model, as shown in Figure 5 , the arc-shaped end surface of the sliding block 4 is provided with a fixed pin 13 and a screw column hole 14.

[0055] It should be noted that, in order to reduce the weight of the sliding block 4, a plurality of weight reduction structures are arranged on the sliding block 4.

[0056] As shown in Figure 1 , Figure 7 , Figure 8 , the utility model provides a sliding door assembly, which comprises a sliding door 21 and a driving mechanism 22 arranged at two ends of the sliding door 21.

[0057] As Figure 1 shown, the sliding door 21 is connected to the arc-shaped end surface of the driving mechanism 22 and can move along the arc-shaped end surface of the driving mechanism 22. This connection structure occupies a small space and can also maintain stable operation.

[0058] As Figure 7 and Figure 8 shown, the sliding door 21 is provided with a bolt through hole 15 and a screw through hole 16.

[0059] The sliding door 21 is driven by the driving mechanism 22 to open or close relative to the air outlet.

[0060] As Figures 1-10 shown, the utility model provides a kind of air conditioner, for floor type cabinet machine, including above-mentioned sliding door component.

[0061] The entire sliding door component is composed of sliding door 21 and upper and lower two driving mechanisms 22, which are driven by motor 3 to drive sliding door 21 to open or close.

[0062] As Figure 3 and Figure 4 shown, the driving box 1 is designed with the fixed part 18 for fixing motor 3, 2 arc-shaped roller sliding groove 6, limiting rib 10, 3 screw columns 17;Driving box cover 2 is designed with the positioning groove 19 for limiting slider 4, 2 arc-shaped roller sliding groove 6, limiting rib 10, 3 screw through holes 16.

[0063] Driving box 1 and driving box cover 2 can be fixed and locked by screw. As Figure 5 shown, slider 4 is designed with the connecting part 20 for being connected with motor 3, 4 fixed grooves 7 for fixing roller 5 (design has reverse buckle structure 12, can buckle the rotating shaft of roller 5, prevent to fall out), 2 sliding door 21 fixed bolt 13 and screw column hole 14. As Figure 7 and Figure 8 shown, the upper and lower ends of the sliding door 21 are each designed with 2 bolt through holes 15 and screw through holes 16, which can be locked on the slider 4 by screw.

[0064] As Figure 1 and Figure 2As shown, the sliding door 21 drive mechanism 22 assembly: first, the motor 3 is assembled in the fixed part 18 of the drive box 1, through 2 fixed screws locking. Then the four rollers 5 are pressed into the fixed groove 7 on the slider 4, the rotating shaft of the roller 5 is buckled through the reverse buckle structure 12 in the fixed groove 7. The slider 4 with the installed roller 5 is fixedly connected with the rotating shaft of the motor 3, and the roller 5 on the slider 4 is aligned into the two arc-shaped roller sliding grooves on the drive box 1. When assembling the drive box cover 2, align the three screw through holes 16 of the drive box cover 2 with the three screw columns on the drive box 1, at this time the two arc-shaped roller sliding grooves 6 of the drive box cover 2 will also be pressed to the roller 5 on the slider 4. Ensure that the roller 5 of the slider 4 is pressed in the middle of the two arc-shaped roller sliding grooves of the drive box 1 and the drive box cover 2, and finally lock the drive box 1 and the drive box cover 2 through the three screws. The upper end of the sliding door 21 is positioned on the slider 4 through the latch, and the lower end is also operated and fixed by two screws. The sliding door 21 is fixed.

[0065] As shown, Figure 9 During operation, the roller 5 of the slider 4 rolls in the arc-shaped roller sliding groove of the drive box 1 and the drive box cover 2 through the driving of the motor 3, and drives the slider 4 to move back and forth. The drive box 1 and the drive box cover 2 are designed with a limiting rib 10, which will be stopped by the limiting rib 10 when the slider 4 is in position, and the motor 3 will be locked together with the slider 4. Specifically, the normal slider needs to rotate 46° from left to right, at this time the program can control the motor to rotate 50°, and the extra 4° can ensure that the slider can reach the right side before the motor stops, avoiding the running not in place due to motor virtual position, assembly virtual position and the like. When the slider reaches the right side, the motor has not stopped, and the slider still has the force to the right. At this time, the limiting rib will stop the slider and limit the slider to continue to the right.

[0066] In this embodiment, the limiting rib requires sufficient strength, and the width can be more than 3mm.

[0067] As shown in Figure 9 and Figure 10 During the operation of the slider 4, the four rollers 5 share the stress, ensuring that the slider 4 can always maintain a horizontal state during operation, avoiding abnormal stress caused by the inclination of the slider 4, and causing problems such as abnormal noise and jamming. At the same time, the motor 3 directly transmits force to the slider 4, reducing the transmission process of the gear to the rack. The force transmission is motor 3—slider 4—sliding door 21, rather than the conventional motor 3—gear—slider 4 (or rack)—sliding door 21. Reducing the gear and rack transmission, avoiding the movement abnormality caused by the precision of the tooth shape, the virtual position of the meshing, etc., making the mechanism more stable and reliable.
