[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] like Figures 1 to 14 As shown, the present invention provides a variable track motion assembly 400, comprising: a slider 1, the slider 1 is movably arranged on the component to be installed along a predetermined track, and the extension direction of the predetermined track is variably arranged; a first roller 2, the first roller 2 is rotatably arranged around its own center line for rolling contact with the component to be installed; a connecting portion 3, the connecting portion 3 is connected to the first roller 2, the connecting portion 3 includes two limiting ribs 31 arranged at intervals along the rotation axis of the first roller 2 and parallel to the rotation axis of the first roller 2, a limiting portion 10 is arranged on the slider 1, the limiting portion 10 includes two limiting grooves 11 arranged at intervals along the predetermined direction, so as to respectively install the two limiting ribs 31; wherein, the width of each limiting groove 11 is greater than the width of the corresponding limiting rib 31, and the projections of the two limiting grooves 11 on a predetermined plane perpendicular to the predetermined direction do not completely overlap, so that the extension direction of the limiting rib 31 changes with the change of the movement direction of the slider 1, so that the first roller 2 maintains a rolling state.

[0045] In this way, the variable track motion component 400 of the present invention can keep the first roller 2 and the component to be installed in a rolling state at all times, and converts the sliding friction between the first roller 2 and the component to be installed when the slider 1 changes track into rolling friction, thereby solving the problem of large sliding friction between the roller on the slider in the drive box of the air conditioner in the prior art and the box body of the drive box when the slider changes track, making the movement of the slider 1 smoother when changing track, making the force borne by the door panel during the movement relatively balanced, reducing the jitter and noise of the door panel during the movement, avoiding wear on the first roller 2, etc., improving the user's comfort experience, ensuring the service life of the drive box, and at the same time reducing the precision requirements for parts, so that only a single motor is set to reliably and effectively control the opening and closing of the door panel, thereby reducing the processing cost of the air conditioner.

[0046] like Figure 4 and Figure 6As shown, one limiting groove 11 includes a first limiting surface 111 and a second limiting surface 112 spaced apart along its width direction, and the other limiting groove 11 includes a third limiting surface 113 and a fourth limiting surface 114 spaced apart along its width direction, the first limiting surface 111 and the third limiting surface 113 are located on the first side of the connecting portion 3, and the second limiting surface 112 and the fourth limiting surface 114 are located on the second side of the connecting portion 3; the first limiting surface 111 and the second limiting surface 112 are parallel to the limiting groove 11. The distance in the width direction is L1, the distance between the first limiting surface 111 and the second limiting surface 112 in the width direction parallel to the limiting groove 11 is L2, the distance between the first limiting surface 111 and the fourth limiting surface 114 in the width direction parallel to the limiting groove 11 is L3, the distance between the second limiting surface 112 and the third limiting surface 113 in the width direction parallel to the limiting groove 11 is L4, and the width of the limiting rib 31 is B; wherein, L4>L2>L3, and L4>L1>L3. In this way, the maximum change position of the connecting part 3 can be limited, so that the first roller 2 can flexibly adjust its posture according to the change of the predetermined trajectory, ensure the stable rolling of the first roller 2 on the component to be installed, reduce the shaking and noise of the variable track motion assembly 400 during the movement, and is suitable for occasions requiring high-precision motion control, and improves the user experience.

[0047] Specifically, 1mm≤L1-B≤5mm; and / or 1mm≤L2-B≤5mm; and / or 0mm<L3-B≤0.2mm; and / or 4mm≤L4-B≤10mm. This ensures the smoothness of the movement of the first roller 2, while also avoiding the unstable movement of the first roller 2 caused by an excessively large gap, thereby improving the stability and reliability of the variable track motion assembly 400.

[0048] like Figure 7 As shown, the connecting portion 3 also includes a rotating connecting block 32, and the first roller 2 is rotatably arranged on the rotating connecting block 32 around its own center line and is located on the side of the rotating connecting block 32 away from the slider 1; the center line of the rotating connecting block 32 is perpendicular to the rotation axis of the first roller 2, and the two limiting ribs 31 are respectively connected to the two ends of the rotating connecting block 32, so that the connecting portion 3 rotates relative to the limiting portion 10 around the center line of the rotating connecting block 32 when the extension direction of the two limiting ribs 31 changes with the movement direction of the slider 1, so that the first roller 2 can adjust its posture more flexibly.

[0049] like Figure 4 and Figure 6 As shown, the rotation angle of the connecting portion 3 in the extension direction is A, wherein A≤50 degrees. Thus, by limiting the rotation angle, it can be ensured that the first roller 2 will not exceed the predetermined range when adjusting the direction, thus avoiding unstable factors during the movement, and is suitable for occasions that require stable movement within a certain angle range.

[0050] Specifically, the rotation angle of the connecting portion 3 in the extension direction is A, wherein A≤23 degrees. Such a smaller rotation angle limit makes the first roller 2 more accurate in adjusting the direction, and is suitable for occasions requiring high-precision motion control.

[0051] like Fig.12 and Fig.13 As shown, the variable track motion assembly 400 includes a supporting connector 4 and an elastic member 5. The large end of the supporting connector 4 is located on one side of the slider 1. The first end of the supporting connector 4 passes through the slider 1 and reaches the other side of the slider 1 to be fixedly connected with the first roller 2 or the connecting portion 3. The elastic member 5 is sleeved on the supporting connector 4 and is located between the slider 1 and the connecting portion 3 to keep the first roller 2 in contact with the component to be installed. In this way, the first roller 2 can always maintain good contact with the component to be installed during the movement, reducing the shaking and noise of the first roller 2 during the movement.

[0052] Specifically, the elastic member 5 may be a compression spring. This further optimizes the sound generated by the variable track motion assembly 400 during the motion process and reduces the precision requirements on the components of the variable track motion assembly 400.

[0053] like Figures 1 to 6 As shown, there are multiple connecting parts 3, and the multiple connecting parts 3 are arranged at intervals on the slider 1; there are multiple first rollers 2 and connecting parts 3, and the multiple first rollers 2 are arranged in a one-to-one correspondence with the multiple connecting parts 3 through the multiple connecting parts 3, which further improves the stability and reliability of the variable track motion assembly 400.

[0054] like Figures 8 to 14 As shown, the present invention provides a driving mechanism, including: a driving box 100 and a driving box cover 200, the driving box 100 and the driving box cover 200 cooperate with and are connected to each other to jointly enclose an installation space; the above-mentioned variable track motion component 400, the variable track motion component 400 is movably arranged in the installation space along a predetermined track; a driving component 300, the driving component 300 is at least partially arranged in the installation space and is drivingly connected to the slider 1 of the variable track motion component 400 to drive the slider 1 to slide, and the first roller 2 of the variable track motion component 400 is used to roll in contact with one of the driving box 100 and the driving box cover 200.

[0055] like Figures 10 to 14As shown, a first guide groove 110 extending along a predetermined track is provided on one of the drive box 100 and the drive box cover 200, and a deceleration structure 120 is provided on the first guide groove 110. The deceleration structure 120 is used to contact the first roller 2 to prompt the first roller 2 to move to a predetermined position. This is more timely and accurate than the method of adjusting the motor speed by judging the number of steps of the motor. Even if the user manually adjusts the door panel position during the process, the deceleration position of the first roller 2 will not change, achieving the purpose of mechanical anti-pinch finger, and the setting of the deceleration structure 120 has relatively low precision requirements on the drive box 100 and the drive box cover 200 and other parts, reducing the impact of the assembly error of the drive mechanism. Regardless of the position of the first roller 2 in the first guide groove 110, it can be adaptively adjusted by the elastic member 5 on the slider assembly.

[0056] like Figures 10 to 14 As shown, the deceleration structure 120 includes a connected plane section 121 and a ramp section 122, the plane section 121 is parallel to and higher than the bottom surface of the first guide groove 110, and the two ends of the ramp section 122 are respectively connected to the plane section 121 and the bottom surface of the first guide groove 110, so that the first roller 2 can move smoothly to the plane section 121 during the movement, reducing the impact and noise of the first roller 2 during the movement.

[0057] like Fig.11 and Fig.13 As shown, the angle between the ramp section 122 and the bottom surface of the first guide groove 110 is C, wherein the value range of C is 0.5 degrees ≤ C ≤ 3 degrees; and / or the height of the plane section 121 is H, wherein the value range of H is 0.3 mm ≤ H ≤ 0.8 mm; and / or the length of the ramp section 122 is L5, wherein the value range of L5 is 10 mm ≤ L5 ≤ 30 mm. In this way, it is possible to accurately determine whether the first roller 2 reaches the predetermined position during the movement, and no additional resistance or impact is generated on the first roller 2 due to improper setting of the angle or length of the ramp section 122.

[0058] Specifically, the angle between the slope section 122 and the bottom surface of the first guide groove 110 is C, where C=1 degree; and / or the height of the plane section 121 is H, where H=0.5 mm; and / or the length of the slope section 122 is L5, where L5=20 mm. This ensures that the first roller 2 reaches the predetermined position in an optimal manner during the movement, reduces the energy loss of the first roller 2 during the movement, and can serve as a reminder to the user.

[0059] like Figure 1 , Figure 2 and Fig.14As shown, a first guide groove 110 extending along a predetermined trajectory is provided on the drive box 100, a second guide groove extending along the predetermined trajectory is provided on one of the drive box covers 200, the first roller 2 is located on the side of the slider 1 close to the drive box 100 to contact the first guide groove 110, and the variable track motion assembly 400 also includes: a second roller 7, the second roller 7 is rotatably arranged on the slider 1 around its own center line and is located on the side of the slider 1 close to the drive box cover 200 to contact the second guide groove; and / or a guide component 8, a first mounting column is provided on the side of the slider 1 close to the drive box 100, and the guide component 8 is sleeved outside the first mounting column to contact the first guide groove 110; and / or an elastic sleeve 6, a second mounting column is provided on the side of the slider 1 close to the drive box cover 200, and the elastic sleeve 6 is sleeved outside the second mounting column to contact the second guide groove.

[0060] The present invention also provides an air conditioner, comprising the above-mentioned driving mechanism, the air conditioner also comprising a shell and a door panel, the shell is provided with an air outlet, the door panel is movably arranged on the shell and located at the air outlet through the driving mechanism to open or close the air outlet.

[0061] Specifically, the air conditioner of the present invention is a cabinet air conditioner, and one of the drive box 100 and the drive box cover 200 of the drive mechanism is connected to the outer casing of the cabinet air conditioner, and the door panel is connected to the slider 1 of the variable track motion assembly 400 in the drive mechanism to move with the slider 1. Most of the predetermined trajectory of the door panel is a regular circular trajectory, and only in the section where it is about to close or just opened, there is a forward or backward change trajectory.

[0062] Among them, the upper and lower sides of the door panel are connected to the outer shell through two variable track motion components 400 respectively, so that the size fluctuation range of the door panel can have an adaptive process. In a hot or cold environment, the influence of thermal barrier and shrinkage of the door panel is small, which effectively prevents the variable track motion component 400 from causing abnormal problems such as jamming and noise due to changes in ambient temperature, thereby improving the reliability of the air conditioner.

[0063] When the door panel moves along an arc trajectory in a predetermined trajectory, the extension direction of each limiting rib 31 of the connecting part 3 is parallel to the side wall of the corresponding limiting groove 11, so that it rolls with the sliding of the slider 1; when the door panel moves along a changing trajectory in the predetermined trajectory, the first roller 2 rotates a certain angle around the center line of the rotating connecting block 32 with the connecting part 3, so that it rolls with the sliding of the slider 1.

[0064] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0065] The variable track motion assembly 400 of the present invention includes: a slider 1, which is movably arranged on the component to be installed along a predetermined trajectory, and the extension direction of the predetermined trajectory can be variably arranged; a first roller 2, which is rotatably arranged around its own center line for rolling contact with the component to be installed; a connecting part 3, which is connected to the first roller 2, and the connecting part 3 includes two limiting ribs 31 arranged at intervals along the rotation axis of the first roller 2 and are both parallel to the rotation axis of the first roller 2. A limiting part 10 is arranged on the slider 1, and the limiting part 10 includes two limiting grooves 11 arranged at intervals along the predetermined direction to respectively install the two limiting ribs 31; wherein the width of each limiting groove 11 is greater than the width of the corresponding limiting rib 31, and the projections of the two limiting grooves 11 on a predetermined plane perpendicular to the predetermined direction do not completely overlap, so that the extension direction of the limiting rib 31 changes with the change of the movement direction of the slider 1, so that the first roller 2 maintains a rolling state. In this way, the variable track motion component 400 of the present invention can keep the first roller 2 and the component to be installed in a rolling state at all times, and converts the sliding friction between the first roller 2 and the component to be installed when the slider 1 changes track into rolling friction, thereby solving the problem of large sliding friction between the roller on the slider in the drive box of the air conditioner in the prior art and the box body of the drive box when the slider changes track, making the movement of the slider 1 smoother when changing track, making the force borne by the door panel during the movement relatively balanced, reducing the jitter and noise of the door panel during the movement, avoiding wear on the first roller 2, etc., improving the user's comfort experience, ensuring the service life of the drive box, and at the same time reducing the precision requirements for parts, so that only a single motor is set to reliably and effectively control the opening and closing of the door panel, thereby reducing the processing cost of the air conditioner.
