According to the above description, the occupancy prevention massage chair mainly comprises the massage chair main body 1 and the control mechanism. The massage chair main body 1 includes a base 11, a seat frame 12, and a back frame 13. The two inner sides of the chair seat framework 12 are respectively fixed with the front end of a rotating mechanism 2 in a rotating way; the two outer sides of the chair back framework 13 are respectively fixed with the front end of a back rotating mechanism 3 in a rotating way. The control mechanism comprises a PLC controller, a seat inductor, a back inductor and a voice prompt module. The seat sensor is used for sensing whether a person sits on the seat of the massage chair, and the back sensor is used for sensing whether the person lies down and leans against the back of the massage chair after sitting. The PLC controller receives signals from the seat sensor and the back sensor, when sensing that a person sits on the massage chair, the person does not pay for use within a certain time or still sits on the seat for a long time after the massage is finished (the time interval can be set to 3-5 minutes), and after sensing the signals, the PLC controller firstly sends out prompt sound (the time length can be set to 2 minutes) through the voice prompt module to remind a user of paying for use again. If the person occupying the seat continuously occupies the seat, the PLC firstly continuously gives an alarm through the voice prompt module to indicate that the chair back and the chair seat of the massage chair are about to start to push, so as to remind the person occupying the seat to leave, then the PLC firstly controls the back rotating mechanism 3 to push, and then controls the seat rotating mechanism 2 to push, so that the person occupying the seat cannot reach a comfortable posture, the person occupying the seat is promoted to leave the massage chair, and the effect of preventing the person occupying the seat is achieved. After the seat sensor and the back sensor sense that the person leaves, the back rotating mechanism 3 and the seat rotating mechanism 2 are controlled to reset through the PLC.

Particularly, the speed of the pushing process of the seat rotating mechanism 2 and the back rotating mechanism 3 is relatively slow, and the time for the seat occupying person to react and leave the massage chair is reserved along with the prompt sound sent by the voice prompt module, so that the aim of preventing the seat occupying is fulfilled on the premise of ensuring the personal safety of the seat occupying person.

Further, the seat rotating mechanism 2 comprises a seat turning plate 21, a seat fixing seat 22, a seat cylinder 23, a seat hinge seat 24 and a seat front shaft 25; the seat front shaft 25 is horizontally arranged, and two ends of the seat front shaft are respectively fixed on two sides of the front end of the seat frame 12; the front ends of the two seat turning plates 21 are respectively and rotatably fixed on two sides of the seat front shaft 25; the seat fixing seat 22 is fixed in the middle of the seat frame 12; the seat hinge seat 24 is fixed at the lower end of the rear part of the seat turning plate 21; the lower end of the seat cylinder 23 is hinged at the upper end of the seat fixing seat 22, and the upper end of a piston rod at the upper end of the seat cylinder is hinged with the lower end of the seat hinge seat 24; the PLC is in electric signal connection with the seat cylinder 23 and controls the seat cylinder 23 to work.

Further, the back rotating mechanism 3 comprises a back turning plate 31, a back shaft 32, a rod slideway 33, a back air cylinder 34, a driving push rod 35 and a rotating push rod 37; the two back side shafts 32 are horizontally arranged, and one ends of the two back side shafts are respectively fixed at the outer side of the middle part of the chair back framework 13; the front end of the back turnover plate 31 is rotationally fixed at the other end of the back shaft 32; one rod slideway 33 is fixed below the middle parts of the two chair back frameworks 13; the rod chute 33 includes a pushing rail 331 fixed to the seatback frame 13 and a rotating rail 332 fixed to an upper end of the pushing rail 331; the lower end of the back air cylinder 34 is fixed in the pushing track 331, and the upper end of a piston rod at the upper end of the back air cylinder is hinged with the lower end of the driving push rod 35; the lower end of the driving push rod 35 is movably arranged in the pushing track 331 and can slide along the pushing track 331; the middle part of a horizontal extension rod 36 is fixed at the upper end of the driving push rod 35, and the extension rod 36 is movably arranged in the rotating track 332 and can slide along the rotating track 332; after the two ends of the extension rod 36 penetrate through the rotating track 332, the extension rod is respectively fixed to the lower end of the rotating push rod 37 in a rotating manner; a back plate slideway 311 is fixed at the lower end of the rear part of the back turnover plate 31; the upper end of the rotating push rod 37 is arranged in the backboard slideway 311 in a sliding way; the PLC is in electric signal connection with the back air cylinder 34 and controls the back air cylinder 34 to work.

The avoiding groove 26 is mainly used for reserving an avoiding space to prevent the seat turning plate 21 from interfering with the seat frame 12 or the back turning plate 31 from interfering with the back frame 13, so as to ensure the smooth and unimpeded movement of the seat turning plate 21 or the back turning plate 31.

Furthermore, the upper ends of U-shaped pipes 14 with upward openings are respectively fixed at the lower ends of the middle parts of the two chair back frameworks 13; the pushing rail 331 is fixed to the upper end of the middle portion of the U-shaped tube 14.

Furthermore, a stable seat 15 is respectively fixed on the outer sides of the middle parts of the two chair back frameworks 13 in a rotating manner; the rotating push rod 37 is slidably sleeved in the stabilizing seat 15. The stabilizing base 15 is mainly used for improving the stability of the rotating push rod 37 during lifting.

Further, the angle between the pushing track 331 and the rotating track 332 is a right angle or an obtuse angle, so that the driving push rod 35 can be driven by the back cylinder 34 to operate normally and smoothly.

In particular, as a preferable aspect of the present embodiment, the pushing rail 331 and the rotating rail 332 form a right angle, and the pushing rail 331 and the seat back frame 13 are arranged in parallel.

According to the above description, the back rotation mechanism 3 includes the bracket 41, the driving gear 42, the driven gear 43, and the L-shaped jack 44. The bracket 41 is a housing, and mainly plays a role of protection, protecting the normal operation of the driving gear 42 and the driven gear 43. The driving gear 42 is provided with a motor, and is driven by the motor to drive the driven gear 43 which is internally neutralized to work. The long side of the L-shaped push rod 44 is fixed on the rotating shaft where the driven gear 43 is located, and the short side thereof is horizontally arranged above the chair back frame 13. In the rotation process of the driven gear 43 along with the driving gear 42, the L-shaped mandril 44 can gradually rise to play a role in pushing the waist and the back of a person occupying the seat, so that the person occupying the seat is promoted to leave the massage chair.
