The diameters of the upper clutch upper plate 41-1 and the upper clutch lower plate 41-3 are larger than the diameter of the upper clutch middle plate.

The diameters of the lower clutch upper plate 14-1 and the lower clutch lower plate 14-3 are larger than the diameter of the lower clutch middle plate.

Now the use method of the lift-type multifunctional deformable smart table provided by the present invention is described as follows:

When the user wants to adjust the height of the lift-type multi-functional deformable smart table, the second motor 5 is started first, and the position of the lower clutch 14 is raised through the lower driving screw 17 and the lower clutch fork 14-2. The upper end of the lower clutch stub shaft 14-4 on the lower clutch 14 will be inserted into the socket on the lower bull gear power selector 11, and the lower end of the lower clutch stub shaft 14-4 will be driven from the lower main shaft sleeve power selector 15 will come out of the socket, so the large motor 5 will lose connection with the transmission spindle 40. Start the large motor 5, thereby driving the bottom large gear 19 to rotate through the large motor gear 16, so as to transmit the power to the lower clutch 14 through the lower clutch long shaft 14-2. Parts other than the lower clutch fork 14-3. Then the power is transmitted to the lower large gear 10; the lower large gear 10 then drives the gears 12 on both sides of the lower large gear to rotate, thereby driving the screw nut 23 fixed with the gears 12 on both sides of the lower large gear to rotate. The lead screw nut 23 will rotate relative to the ball screw 21 it is sleeved on, thereby driving the ball screw 21 to rise or fall, and then drive the second table top 20 and all the components on it to rise or fall together until the top table is on the top. 24 reaches a suitable height and stops the operation of the large motor 5 .

When the user wants to unfold or retract the upper sector table top 26, the second motor 5 is activated to lower the position of the lower clutch 14 through the lower drive screw 17 and the lower clutch fork 14-2. The upper end of the clutch stub shaft 14-4 will come out from the socket on the lower large gear power selector 11, and the lower end of the lower clutch stub shaft 14-4 will be inserted into the socket on the lower main shaft driven sleeve power selector 15 Therefore, the large motor 5 will lose connection with the lower large gear 10. The second motor 52 is activated, and the position of the upper clutch 41 is raised by the upper clutch fork 41-2. At this time, the upper clutch protrusion 41-4 on the upper clutch upper plate 41-1 will be inserted into the upper rotating plate power receiver 32. The upper clutch protrusions 41-4 on the upper clutch lower plate 41-3 will come out from the multiple holes on the sheave sleeve power receiving plate 51; start the large motor 5, by This drives the bottom large gear 19 to rotate through the large motor gear 16, so that the power is sequentially transmitted to the transmission main shaft 40 through the lower clutch 14 and the lower main shaft driven sleeve 13, and drives the transmission main shaft 40 and the upper clutch 41. Components other than the fork Rotate together, and then the power is transmitted to the first-layer rotating plate 28 through the upper-layer rotating plate power receiver 32; the rotation of the first-layer rotating plate 28 drives the upper-layer L-shaped bending plate 31 to rotate, which is formed by the rotation of the upper-layer L-shaped bending plate 31. The distance difference can realize the expansion and contraction of the upper fan-shaped desktop 26 . Since the bearing rollers 24-1 on the bottom surface of the table top 24 on the top layer can slide on the curved surface of the top of the space cam 29, the up and down of the table top 24 on the top layer will be realized according to the height difference of the circumferential wall of the space cam 29; The table top 24 moves outward along the upper table top sliding rail 27 until it moves from below the top table top 24 to the outside and unfolds, the bearing roller 24-1 will be located in the low recess of the top curved surface of the space cam 29, so that the top top table 24 and The height of the upper fan-shaped desktop 26 is the same. When the upper fan-shaped table top 26 shrinks, the bearing roller 24-1 will be located on the inclined surface of the top curved surface of the space cam 29, thereby driving the top top table top 24 to rise as a whole, leaving space for the retracted upper fan-shaped table top 26. Finally, the operation of the large motor 5 is stopped.

When the user wants to unfold or retract the lower sector table top 34, on the premise that the large motor 5 is disconnected from the lower large gear 10, the second motor 52 is activated to lower the position of the upper clutch 41 through the upper clutch fork 41-2 , at this time, the upper clutch protrusion 41-4 on the upper clutch upper plate 41-1 will be disengaged from the plurality of sockets on the upper rotating plate power receiver 32, and the upper clutch protrusion on the upper clutch lower plate 41-3. The starter 41-4 will be inserted into the multiple sockets on the power receiving plate 51 of the sheave sleeve; start the large motor 5, thereby driving the bottom large gear 19 to rotate through the large motor gear 16, so as to pass the power through the lower clutch 14 in turn , The lower main shaft driven sleeve 13 is transmitted to the transmission main shaft 40, which drives the transmission main shaft 40 and the components other than the shifting fork on the upper clutch 41 to rotate together, and then the power is transmitted to the cylindrical cam 47 through the sheave sleeve power receiving plate 51; The cylindrical cam 47 then drives the sheave dial 43 connected to it to rotate; when the dial needle 43-3 on the sheave dial 43 enters the bar groove 42-2 on the sheave 42, it will make the sheave 42 Drive the upper sheave gear 45 to rotate together; the sheave upper gear 45 drives the cam sleeve 50 and the lower fan-shaped unfolding rotating part 48 to rotate through the sheave sleeve gear 44, thereby transmitting the power to the lower desktop unfolding rotating part 37; Driven by the lower table top unfolding rotating member 37, the lower L-shaped bent plate 36 starts to rotate, thereby driving the lower fan-shaped table top 34 to move outward along the lower table top slide rail 35, until it moves from the bottom of the top table top 24 to the outside and unfolds. During this process, the inner end of the metal rod 49 of the lower fan-shaped rotating member will move to the lower horizontal section in the groove 47-1 of the cylindrical cam 47 to the junction of the horizontal section and the threaded section, and the setting needle 43-3 has now been The sheave wheel 42 is driven to rotate 1/4 of a circle, and is just separated from the bar-shaped groove 42-2; The wheel 42 and the gear 45 on the sheave are stuck and no longer move, and the cam sleeve 50 is stuck and no longer rotates, but the cylindrical cam 47 is still rotating under the drive of the transmission spindle 40, so that the cylindrical cam 47 and the cam sleeve are still rotating. A relative movement is generated between 50 and 50, so that the metal rod 49 of the lower fan-shaped rotating member slides along the spiral section of the groove 47-1 on the cylindrical cam 47. The structure is lifted as a whole until the lower fan-shaped table top 34 rises to be flush with the upper table top 24 , so as to realize the overall expansion of the table top, and finally stop the operation of the large motor 5 . The contraction process is the opposite of the expansion process described above.

Through the combination of the above processes, the lifting and lowering, shrinking and unfolding of the lift-type multifunctional deformable smart table can be realized.
