DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0023] A moving mechanism of a slide plate in an intelligent sofa comprises two sets of side plates 1, a back plate 2 connecting the two sets of side plates 1, a box body 3 located between the side plates 1 and the back plate 2, and a flexible seat cushion 4 located above the box body 3:

[0024] On the side wall of the side plate 1, two groups of strip-shaped grooves 5 are vertically arranged. A rectangular frame 6 adapted to the strip-shaped grooves 5 is arranged in the strip-shaped grooves 5. On an inner wall of the rectangular frame 6, a rack 7 is vertically arranged. A gear I8 meshing with the rack 7 is also arranged in the rectangular frame 6. A polygonal installation groove 9 is arranged at the center of the gear I8. A circular tube 10 corresponding to the gear I8 is arranged in the box body 3. The inner opening of the circular tube 10 is polygonal. Both ends of the circular tube 10 are fixed on the side wall of the box body 3 through bearings. Cross bars 11 are arranged at both ends inside the circular tube 10. One end of each cross bar 11 extends into the corresponding installation groove 9. The size of the cross bar 11 is adapted to the inner opening of the circular tube 10 and the size of the installation groove 9. A strip-shaped opening 12 is arranged on the side wall of the circular tube 10 at the other end of the cross bar 11. A slider 13 passing through the strip-shaped opening 12 is arranged at the end of the cross bar 11. The two sliders 13 on the circular tube 10 are movably connected through a connecting mechanism 14. A toothed ring 15 is also arranged on the circular tube 10. A gear II16 meshing with the toothed ring 15 and driven by a motor 17 is arranged on the toothed ring 15.

[0025] In this embodiment, the number of the circular tubes 10 and the number of the toothed rings 15 are both two groups. The gear II16 is located between the two groups of toothed rings 15 and meshes with them.

[0026] As Figure 6 shown, the teeth on one side of the gear I8 mesh with the rack 7. The teeth on the other side of the gear I8 are in contact with the corresponding side wall of the rectangular frame 6. The rectangular frame 6 is made of a metal material and is fixed in the strip-shaped groove 5.

[0027] As Figure 3 shown, the connecting mechanism 14 includes a screw rod 141 arranged on the corresponding slider 13. The two corresponding screw rods 141 are connected through a screw tube 142. A convex seat 143 for the screw tube 142 to pass through is also arranged on the circular tube 10. A bearing sleeved on the screw tube 142 is arranged on the convex seat 143.

[0028] In this embodiment, a U-shaped metal plate 18 is fixed on the front side of the box body 3. The opening of the metal plate 18 is buckled on the front ends of the two side plates 1. By pulling the front ends of the two side plates 1 through the metal plate 18 and by the box body 3 resisting the inner walls of the two side plates 1, the stability between the two side plates 1 is effectively improved, and the distance between the front ends of the two side plates 1 is prevented from changing.

[0029] As Figure 2 、 4As shown, a T-slot 19 is vertically arranged on the side wall of the strip groove 5 in the opening of the rectangular frame 6, a circular block 20 is arranged in the horizontal end of the T-slot 19, a fixing rod 21 connected to the middle of the back side of the gear I8 is arranged at the center of the circular block 20, a screw hole 22 is arranged in the middle of the inner bottom wall of the mounting groove 9, a fixing channel 23 corresponding to the screw hole 22 is arranged in the middle of the cross bar 11, a screw rod 24 is threaded in the fixing channel 23, one end of the screw rod 24 extends into the corresponding screw hole 22 and is threaded and fixed thereto, and a gear III25 located outside the fixing channel 23 is arranged at the other end of the screw rod 24, wherein operation openings 26 are correspondingly arranged on the two side walls of the circular tube 10 on the same side as the gear III25, and the straight line formed by the two groups of operation openings 26 is arranged tangent to the gear III25.

[0030] The method of using the present invention is as follows: during installation, the box body 3 is slid into the opening formed between the two sets of side panels 1 and the back panel 2, and at the same time, the box body 3 drives the opening of the metal plate 18 to buckle at the front end of the two sets of side panels 1. At this time, the box body 3 is opened from the top, and the round tube 10 is fixed, and the screw tube 142 is rotated to make it rotate on the bearing and screw rod 141 in the convex seat 143, thereby expanding the distance between the two sets of screw rods 141 inside, so that the screw rod 141 moving outward drives the slider 13 to slide in the strip opening 12, and also drives the cross bar 11 in The round tube 10 slides outward from the opening, and at this time, the round tube 10 is slightly rotated to drive the cross bar 11 to rotate to adjust its angle, so that the end of the cross bar 11 can smoothly slide into the installation groove 9. In this process, since the gear I8 is engaged with the rack 7, the gear I8 will not move up and down in the rectangular frame 6 without rotating it, but will be suspended in the air. The side wall of the horizontal end of the T-slot 19 abuts against the circular block 20, and the circular block 20 pulls the gear I8 through the fixing rod 21 to effectively prevent it from sliding out of the opening of the rectangular frame 6.

[0031] When the end of the cross bar 11 slides into the mounting groove 9, the driving rack used to drive the gear III25 passes through the two sets of operating openings 26. At this time, the driving rack in the round tube 10 is meshed with the gear III25, and the gear III25 is driven to rotate by pulling the driving rack. The gear III25 drives the screw rod 24 to rotate in the fixing channel 23 and then slides into the screw hole 22 to be screwed and fixed thereto, thereby completing the assembly of the sofa. At the same time, the disassembly steps are opposite.

[0032] The present invention prevents the gear I8 from being displaced up and down or horizontally by clamping the gear I8 through the rectangular frame 6 and the rack 7, and the gear I8 can limit the box body 3 through the cross bar 11 and the round tube 10 to prevent the box body 3 from being displaced in the opening formed between the side panel 1 and the back panel 2 without human intervention. At the same time, the screw rod 24 is screwed to the fixed channel 23 and the screw hole 22 on the gear I8, and the T-slot 19 pulls the screw rod 24, the cross bar 11 and the round tube 10 through the fixed rod 21 and the gear I8, thereby further strengthening the connection stability between the box body 3 and the side panel 1 and other components, and preventing the opening between the two sets of side panels 1 from opening outward.

[0033] When it is necessary to clean the ground below the box body 3, the motor 17 drives the two sets of gear rings 15 to rotate through the gear II16, and the gear ring 15 clamps the cross bar 11 through the round tube 10 to make it rotate together, and the rotating cross bar 11 abuts against the side wall of the polygonal mounting groove 9 to drive the gear I8 to rotate in the rectangular frame 6 and on the rack 7, so that the gear I8 slowly moves upward in the rectangular frame 6, and then lifts the height of the box body 3 so that its bottom is suspended, so as to facilitate the cleaning of the ground below the box body 3. Finally, when the motor 17 stops working and loses its power interference, the gear teeth of the rack 7 clamp the gear I8, and then the gear I8 is suspended at a high place in the rectangular frame 6 to prevent it from moving, and indirectly suspends the box body 3 at a high place. When the gear I8 rotates and slowly moves upward, it will drive the fixing rod 21 and the circular block 20 to rotate and move upward in the T-slot 19, so that it will not affect the normal operation of the gear I8. When the cleaning is completed, the motor 17 reverses and drives the box body 3 to reset.

[0034] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
