For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0024] In one embodiment of the present invention, Figures 1 to 4As shown, a combined intelligent sofa leg support is provided, comprising a leg support assembly 2 for supporting and lifting a sofa body 1, wherein a base 11 is provided in the sofa body 1, an active cavity 12 is provided in the base 11, and the active cavity 12 is open to the front side of the sofa, the leg support assembly 2 comprises a support plate 21 and a rotating shaft 22, the support plate 21 is rotatably connected to the sofa body 1 through the rotating shaft 22, the support plate 21 covers the opening of the active cavity 12, a slide rail 211 is provided on the back of the support plate 21, a top box 121 and a driving member for driving the top box 121 are provided in the active cavity 12, a top plate 122 extends upward from the front side of the top box 121, the top of the front side of the top plate 122 is fixedly installed with the top rod 123, the other end of the top rod 123 is rotatably connected with a slide seat 124, the slide seat 124 is slidably connected to the slide rail 211, and a drawer box 3 is slidably connected in the top box 121.

[0025] Furthermore, the driving member includes a screw rod 4, a motor 41 and a fixed housing 44. A mounting seat for fixing the two ends of the screw rod 4 is provided at the top of the movable chamber 12. The motor 41 is installed at the top of the top box 121. A driving wheel 42 is fixed to the output shaft of the motor 41. The screw rod 4 is threadedly connected with a nut 43. The driving wheel 42 is meshed with the outer wall of the nut 43. The driving wheel 42 and the nut 43 are both rotatably connected to the inside of the fixed housing 44. The bottom of the fixed housing 44 is connected to the top of the top box 121. Specifically, when the top box 121 moves, the motor 41 rotates the driving wheel 42, and the power is transmitted to the nut 43 through the driving wheel 42, so that the nut 43 rotates and moves on the screw rod 4, and the nut 43 pushes the fixed housing 44, and the fixed housing 44 transmits the power to the top box 121 through the motor 41, and finally the effect of moving the top box 121 back and forth is achieved, and the top box 121 is moved better.

[0026] Furthermore, the front side of the top plate 122 and the front side of the drawer box 3 are both provided with a decorative surface 5, and the front side of the drawer box 3 is flush with the front side of the top plate 122. Specifically, the drawer box 3 can be pulled out from the top box 121 and stored; in a better use example of pulling out the drawer box 3, the top box 121 is driven forward by the driving unit so that the front side of the top plate 122 is flush with the front side of the sofa base 11, which is more convenient for pulling out the drawer box 3 and storing things. By providing the decorative surface 5, the front side of the top plate 122 can be flush with the front side of the sofa base 11, and the aesthetics of the sofa base 11 can still be maintained, further improving the user's comfort and visual comfort.

[0027] Furthermore, the decorative surface 5 installed on the bottom part of the top plate 122 is provided with a wear-resistant surface 51. Specifically, in the process of the top box 121 moving, in order to ensure the environment in the activity chamber 12, the bottom of the top plate 122 needs to be in contact with the ground at the same time to isolate the large solids in the environment outside the activity chamber 12. By providing the wear-resistant surface 51, the bottom of the top plate 122 can be protected and kept beautiful.

[0028] Furthermore, a plurality of top blocks 13 extend upward from the top of the top plate 122 , and a top rod 123 is installed on the front side of each top block 13 . The number of the top rods 123 is the same as the number of the slide rails 211 .

[0029] Furthermore, the top wall of the movable cavity 12 is provided with a plurality of guide grooves 14, and the guide groove 14 is provided with a plurality of notches 141 downwardly, and each of the top blocks 13 passes through the notches 141 respectively, and the top of each of the top blocks 13 is slidably connected to the top wall of the movable cavity 12, and each of the top rods 123 moves in one of the guide grooves 14. Specifically, the guide groove 14 is invertedly arranged at the top of the movable cavity 12, and the top rod 123 is hidden in the guide groove 14. The top of the top plate 122 is slidably matched with the outer bottom of the guide groove 14, and the top rod 123 moves along the extension direction of the guide groove 14, so as to achieve the effect of lifting the support plate 21 and improve the aesthetics of the interior of the movable groove.

[0030] Furthermore, each of the push rods 123 is coaxially sleeved with a guide rod 15, and the guide rod 15 is slidably connected to the guide groove 14. Specifically, the guide rod 15 is mainly used for sliding guide of both sides of the push rod 123 on the inner side wall of the guide groove 14, so that the push rod 123 can achieve a better linear effect when sliding, and can better lift the support plate 21.

[0031] Furthermore, a pulley 16 is provided at the bottom of the top box 121. Specifically, by providing the pulley 16, the top box 121 can be moved more smoothly. Since the bottom of the top plate 122 needs to be in contact with the ground, it is preferably provided that the top box 121 is supported by the cooperation of the bottom of the top plate 122 and the pulley 16, that is, the pulley 16 is provided at the bottom of the top box 121, the top plate 122 is provided at the front side of the top box 121, and the bottom surface of the top plate 122 is flush with the bottom surface of the pulley 16, thereby achieving a better movement effect of the top box 121 and a better sealing effect in the activity chamber 12.

[0032] Working principle: When in use, the top box 121 is driven forward by the driving member, driving the top rod 123 to lift the support plate 21, and at the same time, the top rod 123 pushes the slide 124 to slide on the slide rail 211. During this process, the slide 124 gradually slides from the head end to the end of the slide rail 211, and at the same time, the angle between the support plate 21 and the base 11 gradually increases. When the slide 124 reaches the end of the slide rail 211, the angle between the support plate 21 and the base 11 is 0°, and the top plate 122 is located at the opening of the active cavity 12, and the front side of the top plate 122 is flush with the front side of the base 11 to prevent foreign matter from entering the active cavity 12. At this time, the drawer box 3 can be pulled out to store items, achieving a more concealed item storage effect.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
