Detailed Implementation

[0023] like Figure 1-3 As shown, this utility model provides a patient rehabilitation chair, including a seat 101, armrests 102, pedals 103 and base 104. The base 104 is equipped with a motor 1042, a lead screw 1043 and two moving blocks 1044. The lead screw 1043 is located at the output end of the motor 1042. The two moving blocks 1044 are sleeved on the outside of the lead screw 1043. The upper surfaces of the two moving blocks 1044 are respectively equipped with a front lifting rod 1046 and a rear lifting rod 1045. A control box 200 is installed on the rear side of the base 104.

[0024] An extension component 300 is disposed on the upper surface of the control box 200. The extension component 300 includes a fixed rod 301, an operating platform 302, a movable rod 304, and a suspension rod 305. The operating platform 302 is sleeved on the outside of the fixed rod 301, the fixed rod 301 is sleeved on the outside of the movable rod 304, and the suspension rod 305 is disposed on the outer side near the top of the movable rod 304.

[0025] Furthermore, in this embodiment, casters 105 are provided around the bottom of the base 104. A drive motor 107 is connected to the inner side of the caster 105 by screws. The drive motor 107 is installed inside the base 104. The output end of the drive motor 107 is connected to the caster 105 for transmission. The drive motor 107 controls the rotation of the caster 105 to realize the position movement of the rehabilitation chair.

[0026] In this embodiment, the surface of the base 104 is provided with a movable groove 1041 for the front lifting rod 1046 and the rear lifting rod 1045 to move. The upper ends of the front lifting rod 1046 and the rear lifting rod 1045 are screwed to the seat 101, and the bottoms of the front lifting rod 1046 and the rear lifting rod 1045 are screwed to the moving block 1044. The lead screw 1043 is threaded to the moving block 1044, and the output end of the motor 1042 is connected to the lead screw 1043 for transmission. The movable groove 1041 provides space for the front and rear lifting rods 1045 to move. The motor 1042 controls the lead screw 1043 to rotate. Based on the thread, the moving block 1044 moves back and forth on its surface according to the rotation direction of the lead screw 1043, thereby driving the movement of the front and rear lifting rods 1045 above.

[0027] In this embodiment, the control box 200 is connected to the rear end of the base 104 by screws. The output end of the control box 200 is electrically connected to the input end of the motor 1042 and the drive motor 107. The control box 200 is equipped with a PLC controller or a microcontroller. An indicator light 201 is installed on the top of the control box 200. The motor 1042, the drive motor 107 and the indicator light 201 are controlled by the PLC controller or microcontroller built into the control box 200. For convenience, a wireless connector can be installed to wirelessly connect to a remote control for wireless control.

[0028] In this embodiment, the fixed rod 301 is screwed to the upper surface of the control box 200 and is offset from the indicator light 201. The fixed rod 301 passes through one side of the operating platform 302 and is slidably connected to the operating platform 302. The movable rod 304 is slidably connected to the fixed rod 301, and the suspension rod 305 is screwed to the movable rod 304, so that both the operating platform 302 and the movable rod 304 can be moved on the fixed rod 301 to adjust their positions.

[0029] In this embodiment, tightening screws 303 are provided between the operating platform 302 and the movable rod 304 and the fixed rod 301. The tightening screws 303 pass through the operating platform 302, the movable rod 304 and the fixed rod 301 respectively, and are threaded together with them. The positions of the operating platform 302 and the movable rod 304 on the fixed rod 301 are limited by tightening screws 303. Several corresponding threaded holes are opened on the fixed rod 301 and the movable rod 304, and one threaded hole is opened on the operating platform 302 to achieve the desired result.

[0030] In this embodiment, an auxiliary wheel 106 is provided at the rear end of the base 104. A connecting rod is provided between the auxiliary wheel 106 and the base 104. The auxiliary wheel 106 is installed at the rear end of the base 104 through the connecting rod. When the moving wheel 105 moves, the auxiliary wheel 106 moves synchronously together. The auxiliary wheel 106 increases the grounding area of ​​the rehabilitation chair and improves stability.

[0031] Specifically, based on the conventional structure of the patient rehabilitation chair, which includes a seat 101, armrests 102, footrests 103, base 104, and casters 105, a movable groove 1041 is provided on the surface of the base 104 to provide space for the front and rear lifting rods 1045 to move. The motor 1042 controls the lead screw 1043 to rotate, which in turn controls the moving block 1044 to move back and forth outside its surface. This drives the front lifting rod 1046 and the rear lifting rod 1045 above the moving block 1044 to move, allowing the position of the seat 101 to be adjusted. Both the front lifting rod 1046 and the rear lifting rod 1045 are electric lifting rods. They are controlled by communicating with the input end of the lifting rods through the output end of the PLC controller or microcontroller in the control box 200. When the lifting rods are raised and lowered synchronously, the seat 101 can be adjusted in height. When the lifting rods are raised and lowered individually, the seat 101 can be adjusted in angle.

[0032] An expansion component 300 is installed on the control box 200. The position is installed by the fixing rod 301. The operating height of the operating platform 302 and the movable rod 304 is adjusted according to the operating habits of medical staff. The position is limited by tightening the screw 303. Then, infusion equipment can be suspended on the suspension rod 305 at the upper end of the movable rod 304. Alternatively, the suspension rod 305 can be removed and replaced with a bracket for installing equipment such as ventilators and oxygen cylinders. Personalized settings can be made according to the patient's treatment situation.

[0033] It is worth noting that the control method in this application is controlled by a PLC controller or a microcontroller. The control circuit of the PLC controller or microcontroller can be implemented by those skilled in the art through simple programming, and is common knowledge in the field. This application will not explain the control method and circuit connection in detail.

[0034] The components of this utility model, such as the seat 101, armrest 102, pedal 103, base 104, motor 1042, lead screw 1043, moving block 1044, rear lifting rod 1045, front lifting rod 1046, moving wheel 105, auxiliary wheel 106, drive motor 107, control box 200, indicator light 201, fixed rod 301, operating platform 302, tightening screw 303, movable rod 304, and suspension rod 305, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
