DETAILED DESCRIPTION

[0020] The utility model is described below in conjunction with the accompanying drawings. The specific implementation methods described herein are only used to illustrate and explain the utility model and are not used to limit the utility model. Without departing from the design spirit of the utility model, various modifications and improvements made to the technical solution of the utility model by ordinary technicians in this field should fall within the protection scope of the utility model.

[0021] like Figures 1 to 5 As shown, the relaxation chair for psychological rehabilitation therapy in this embodiment includes a seat plate 1, and a base 2 is arranged at the bottom end of the seat plate 1. The base 2 in this embodiment includes a bottom plate 21, a support rod 22 connected between the upper surface of the bottom plate 21 and the lower surface of the seat plate 1, and a plurality of universal wheels 23 arranged on the lower surface of the bottom plate 21. In another embodiment, the support rod 22 is a telescopic rod, which can adjust the height of the seat plate 1. Armrests are arranged on both sides of the upper surface of the seat plate 1.

[0022] The rear side of the top of the seat plate 1 is provided with a backing plate 3 through a rotating shaft, and the two sides of the seat plate 1 are provided with a slide groove 11. The inner walls of the two sides of the slide groove 11 are connected to the screw rod 4 through bearings. The outer surfaces of the two screw rods 4 are connected with sliders 5 through threads. The sliders 5 and the slide groove 11 form a sliding fit. The rotation of the screw rod 4 can make the slider 5 move on the screw rod 4. The side wall of the slider 5 located outside the slide groove 11 is provided with a connecting rod 6, and the two ends of the connecting rod 6 are respectively hinged to the side wall of the slider 5 and the side wall of the backing plate 3. The same side ends of the two screw rods 4 are both passed out of the seat plate 1, and specifically, the ends of the screw rods 4 are passed out of the rear end of the seat plate 1.

[0023] Sprocket wheels 7 are installed at the ends of the two screw rods 4 outside the seat plate 1 , and a chain 8 is installed between the two sprocket wheels 7 . Under the action of the chain 8 , the rotation of one sprocket wheel 7 can drive the rotation of the other sprocket wheel 7 .

[0024] On the basis of the above structure, the relaxation chair for psychological rehabilitation therapy of this embodiment further includes a stepper motor 9, a driving gear 10, a driven gear 20, a single chip module 30, a control button 40 and a power module 50. The stepper motor 9 is mounted at the bottom end of the seat plate 1 and close to the end of one of the screw rods 4 extending out of the seat plate 1. The driving gear 10 is mounted on the rotating shaft of the stepper motor 9, and the driven gear 20 is mounted on the end of the screw rod 4 close to the stepper motor 9, and the driving gear 10 and the driven gear 20 are meshed and connected.

[0025] The single-chip microcomputer module 30 and the power module 50 are both arranged on the lower surface of the seat plate 1, and the control button 40 is arranged on the armrest. The single-chip microcomputer module 30 is electrically connected to the stepper motor 9 and the control button 40 respectively. The control button 40 is used to send instructions to the single-chip microcomputer module 30, and the single-chip microcomputer module 30 is used to control the forward and reverse rotation of the stepper motor 9 according to the instructions. The power module 50 is used to provide working voltage. The specific circuit diagram is shown in FIG. Figure 5 As shown, the single-chip microcomputer module 30 of this embodiment adopts a single-chip microcomputer module with an AT89C51 single-chip microcomputer as the core, and a ULN2803 driver chip is arranged between the single-chip microcomputer module 30 and the stepper motor 9 to drive the stepper motor 9 to work. There are two control buttons 40, which are respectively used to control the forward rotation and reverse rotation of the stepper motor 9, and are represented by K2 and K3 in the circuit, and the stepper motor 9 is represented by M in the circuit.

[0026] When it is necessary to adjust the inclination angle of the back plate 3, the control button 40 can be pressed, and the control button 40 sends an instruction to the single-chip microcomputer module 30. The single-chip microcomputer module 30 (a computer program is set in the single-chip microcomputer) controls the stepper motor 9 to rotate forward and reverse according to the instruction. The rotation of the stepper motor 9 can drive the driving gear 10 and the driven gear 20 to rotate, and the rotation of the driven gear 20 can drive the lead screw 4 and the sprocket 7 to rotate, so that the two lead screws 4 rotate, causing the two sliders 5 to move on the two lead screws 4. When the slider 5 moves, it will act on the connecting rod 6, and the connecting rod 6 acts on the back plate 3, thereby rotating the back plate 3 to adjust the inclination angle. This can meet the use needs of different people, and it is defined that when the stepper motor 9 rotates forward, the slider 5 moves in the direction close to the sprocket 7. At this time, the angle between the back plate 3 and the seat plate 1 gradually increases; when the stepper motor 9 reverses, the slider 5 moves in the direction away from the sprocket 7. At this time, the angle between the back plate 3 and the seat plate 1 gradually decreases.

[0027] Therefore, compared with the prior art, the relaxation chair for psychological rehabilitation therapy in this embodiment can adjust the inclination angle of the backrest 3 by using a stepper motor 9 instead of a manual rotary knob, thereby reducing the workload of medical staff.

[0028] The side wall of the front end of the seat plate 1 is provided with a receiving groove 12, and a leg board 60 is provided in the receiving groove 12. The leg board 60 can be pulled out from the receiving groove 12. The leg board 60 is used to place the patient's legs to improve the patient's comfort. The front end of the leg board 60 is provided with a supporting leg 601, and the supporting leg 601 is used to support the leg board 60. In this embodiment, the end of the supporting leg 601 is hinged to the lower plate surface of the leg board 60, and the supporting leg 601 can be rotatably attached to the lower plate surface of the leg board 60. When the leg board 60 is not in use, the leg board 60 and the supporting leg 601 can be stored together in the receiving groove 12. The side wall of the leg board 60 located at the notch of the receiving groove 12 is provided with a pull ring 602, and the pull ring 602 facilitates the leg board 60 to be pulled out from the receiving groove 602. In another embodiment, the supporting leg 601 is a telescopic rod, and the length of the supporting leg 601 can be adjusted according to the height of the seat plate 1.
