DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example

[0026] See Figures 1 to 3 As shown, an adjustable intelligent office sofa chair includes a chair leg 1, a seat plate 2 arranged on the chair leg, a backrest 3 and armrests 4 arranged on the seat plate. In this embodiment, the chair leg is a conventional structure of the prior art, which mainly includes a vertical support rod and a plurality of horizontal support plates at the bottom end of the vertical support rod. The seat plate is a metal plate or a wooden plate or a plastic plate structure, which can be wrapped with a cushion layer.

[0027] In actual application, a control circuit board 5 and a drive motor 6 connected to the control circuit board are fixed to the bottom surface of the seat plate, and a folding plate 7 is fixed on the main shaft of the drive motor; in this embodiment, the control circuit board is a conventional structure of the prior art, and is mainly used for driving and controlling operations of the drive motor and the electric telescopic rod, and the folding plate is a structure such as a plastic plate, a metal plate, or a wooden plate, and the surface of the folding plate is wrapped with a rubber layer 17. When installed and used, the folding plate is attached to the bottom surface of the seat plate, and the rotation of the driving motor drives the folding plate to rotate out from the bottom surface of the seat plate; the bottom of the backrest is connected to the seat plate through a connecting shaft 10, and the bottom of the seat plate is fixed with an electric telescopic rod 8 connected to the control circuit board. The electric telescopic rod is a conventional structure of the prior art and is simply used, so it is not recorded in detail. The end of the electric telescopic rod is connected to the back of the backrest through a C-shaped support rod 9; the two ends of the C-shaped support rod are rotatably connected to the electric telescopic rod and the back of the backrest through pins respectively; in this embodiment, the electric telescopic rod cooperates with the C-shaped support rod to realize the rotation of the backrest around the connecting shaft to achieve vertical or flattening.

[0028] In order to facilitate operation, a switch panel 11 is provided on the armrest, and the switch panel is connected to the control circuit board, which is mainly used for corresponding control operations to improve the convenience of operation.

[0029] In actual application, the front sides of the backrest are provided with limited insertion cavities 12; the bottom of the armrest is rotatably connected to the side of the seat plate through a rotating shaft 13; the end of the armrest is fixed with a limited insertion column 14; when in use, when the backrest is vertical, the limited insertion column of the armrest is inserted into the limited insertion cavity for limiting. Through the above structure, the stability of the position of the armrest and the backrest can be ensured when sitting or standing, and the position accuracy of the armrest can be ensured;

[0030] In actual application, a limiting convex plate 15 is provided on the edge of the seat plate, and the armrest rotates around the rotating shaft and unfolds, and the bottom surface of the armrest abuts against the upper limit of the limiting convex plate. The limiting convex plate can be used to support and limit the armrest when it is flattened to prevent it from falling and ensure the corresponding position is stable. In addition, a locking butterfly screw 16 is provided on the armrest, and the armrest rotates around the rotating shaft and is locked in place by the locking butterfly screw. After rotation, it can be locked and positioned, doubly protecting the position stability and reliability of the armrest.

[0031] Meanwhile, in this embodiment, a battery box 18 is fixed to the bottom surface of the seat plate, and the battery box is connected to the control circuit board, the drive motor and the electric telescopic rod, and is mainly used for power supply, and can also be connected and used through a power cord or the like.

At the same time, the backrest can be in a vertical or flat state under the action of the telescopic electric rod, so as to facilitate the use of the backrest when sitting or lying down. Not only is the adjustment operation more convenient, but it is also conducive to improving the comfort of the sofa chair, and has strong applicability and good practicality.

[0033] At the same time, the armrest is connected to the edge of the seat plate through a rotating shaft and cooperates with the limiting cavity of the backrest. When used as a chair, the end limiting plug column of the armrest is inserted into the limiting cavity for limiting, which can ensure the stability of the armrest. When the backrest is laid flat, the armrest can also be laid flat outward and supported and limited by the limiting convex plate, which is conducive to increasing the lying area and improving the comfort of use. It has strong applicability and good practicality.

[0034] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification can also be directly processed according to existing technical common sense.
