[0033] The electrically controlled supporting back pad 3 is composed of a flip back pad axially mounted on the upper end of the main frame 1 and a bottom support rod for controlling the rear control cover 5 .
[0034] In order to cooperate with installation and lateral adjustment, the rear control cover 5 is fixed on the rear installation back plate 4 by bolts, and lateral telescopic grooves for accommodating the electrically controlled telescopic cover 6 are provided on both sides of the rear control cover 5.
[0035] The fixed support seat cushion 2 and the electrically-controlled support back cushion 3 are laid flat on the main frame 1 at ordinary times and can be used as a medical bed for patients to lie down and rest. When rehabilitation is needed, the electrically-controlled support back cushion 3 can be flipped upward to provide lateral support for the patient's back, changing the lying position to a sitting position. The electrically-controlled telescopic cover 6 is then translated outwardly, and the three-stage electrically-controlled linkage arm 7 is flipped outward. The patient grasps the annular end control mechanism 8 with his wrist to slowly control the three-stage electrically-controlled linkage arm 7, thereby assisting the upper limbs in rehabilitation training. Using the patient to control can effectively reduce the patient's comfort caused by control by others.
[0036] In order to cooperate with the lateral telescopic adjustment, the electrically controlled telescopic cover 6 is fixedly mounted on the inner side of the lateral telescopic groove, and the inner telescopic support rod 61 and the lateral telescopic cover 62 are fixedly mounted on the protruding end of the inner telescopic support rod 61.
[0037] The internal telescopic support rod 61 controls the telescopic adjustment of the lateral telescopic cover shell 62 inside the lateral telescopic slot by telescoping, and the three-stage electric-controlled linkage arm 7 can be completely retracted into the lateral telescopic slot when idle, which can reduce the external structure occupancy of the rehabilitation mechanism and improve the durability of the three-stage electric-controlled linkage arm 7.
[0038] In order to cooperate with adjustment and control, the three-stage electrically controlled linkage arm 7 includes a first electrically controlled flip arm 71 movably installed on the inner wall of the laterally telescopic cover 62, a second electrically controlled flip arm 72 movably installed at the end of the first electrically controlled flip arm 71, a third electrically controlled flip arm 73 movably installed at the end of the second electrically controlled flip arm 72, and an annular control guide rail 74 installed at the end of the third electrically controlled flip arm 73.
[0039] In order to cooperate with internal adjustment, the inner side of the lateral telescopic cover 62 has a first transverse assembly seat 9 at the connection end of the first electrically controlled flip arm 71. The first electrically controlled flip arm 71 includes a first control motor 711 fixedly installed inside the first transverse assembly seat 9, a flip adjustment arm 712 mounted on the outside of the first transverse assembly seat 9, and a worm gear assembly 713 movably installed inside the first transverse assembly seat 9.
[0040] The worm gear assembly 713 consists of a worm axially fixed on the output shaft of the first control motor 711, a worm wheel meshing with the worm, and a gear coaxially fixed with the worm wheel. The gear meshes with the tooth surface on the inner side of the flip adjustment arm 712, so that the first control motor 711 can drive the flip adjustment arm 712 to flip and adjust through the worm gear assembly 713.
[0041] The function of the flip adjustment arm 712 is to flip the second electrically-controlled flip arm 72 and the third electrically-controlled flip arm 73 to the outside, and adjust them to different heights and positions according to people of different heights, so that the second electrically-controlled flip arm 72 and the third electrically-controlled flip arm 73 can be adapted to different rehabilitation populations.
[0042] In order to cooperate with the control of the upper arm, the second electrically-controlled flip arm 72 includes a second control motor 721 fixedly mounted at the end of the flip adjusting arm 712, a second assembly adjustment frame 722 movably assembled at the end of the flip adjusting arm 712, a second annular electrically-controlled adjustment cylinder 723 fixedly mounted on the inner walls on both sides of the second assembly adjustment frame 722, and a second flip arm 724 movably mounted inside the second assembly adjustment frame 722.
[0043] The second flip arm 724 is covered on the inner opening of the second annular electrically controlled regulating cylinder 723 through the second flange cover on the connecting end, so as to close the inner opening of the second annular electrically controlled regulating cylinder 723, and then an internal driving piston matching the second annular electrically controlled regulating cylinder 723 is installed on the second flange connecting surface. Oil inlet holes and oil outlet holes are provided on both sides of the second annular electrically controlled regulating cylinder 723, and the opening and closing states of the oil inlet holes and the oil outlet holes on both sides are controlled by adjusting the reversing valve on the outer side of the second assembly adjusting frame 722, so as to switch the oil inlet and oil outlet in different directions, so as to control the direction of operation of the internal driving piston, so as to change the flipping direction and flipping angle of the second flip arm 724.
[0044] In order to cooperate with the control of the forearm, the third electrically-controlled flip arm 73 includes a third control motor 731 fixedly installed at the end of the second flip arm 712, a third assembly adjustment frame 732 movably assembled at the end of the flip adjustment arm 712, a third annular electrically-controlled adjustment cylinder 733 fixedly installed on the inner walls on both sides of the third assembly adjustment frame 732, and a third flip arm 734 movably installed inside the third assembly adjustment frame 732.
[0045] The third flip arm 734 is covered on the inner opening of the third annular electrically controlled regulating cylinder 733 through the third flange cover on the connecting end to close the inner opening of the third annular electrically controlled regulating cylinder 733, and then an internal driving piston matching the third annular electrically controlled regulating cylinder 733 is installed on the connecting surface of the third flange, and oil inlet holes and oil outlet holes are provided on both sides of the third annular electrically controlled regulating cylinder 733. The opening and closing states of the oil inlet holes and oil outlet holes on both sides are controlled by adjusting the reversing valve on the outside of the third assembly adjusting frame 732, thereby switching the oil inlet and oil outlet in different directions, thereby controlling the direction of operation of the internal driving piston, thereby changing the flipping direction and flipping angle of the third flip arm 734.
[0046] For the convenience of control, the annular end control mechanism 8 includes an internal regulating ring 81 movably assembled inside the annular control guide rail 74, an inner connecting strap 82 installed on the internal regulating ring 81, and an external button 83 installed on the outer side of the annular control guide rail 74 for respectively controlling the second control motor 721, the second annular electric control regulating cylinder 723 and the third annular electric control regulating cylinder 733.
[0047] The patient is installed on the internal adjustment ring 81 by using the inner connecting strap 82 to improve the anti-loosening property of the wrist, and then the palm is positioned between the handles on the inner curved surface of the internal adjustment ring 81. The internal adjustment ring 81 is then controlled to slide in the annular control guide rail 74 by using the movement of the wrist. According to the rotation angle of the internal adjustment ring 81, the third control motor 731 is controlled to rotate, thereby rotating the third assembly adjustment frame 732, thereby changing the flipping direction of the third flip arm 734, so that the forearm can be driven to perform various convenient flip adjustments.
[0048] The external button 83 is composed of a plurality of buttons, which respectively control the forward and reverse rotation of the second control motor 721, the driving mode of the second annular electric-controlled adjusting cylinder 723 and the driving mode of the third annular electric-controlled adjusting cylinder 733, thereby changing the flipping direction of the second flip arm 724 and independently controlling the flipping of the second flip arm 724 or the third flip arm 734.
[0049] In order to improve the operating comfort in cold weather, an embedded electric heating module 10 is installed inside the second flip arm 724 and the third flip arm 734 .
[0050] In order to facilitate activities and improve rehabilitation effects, it is necessary to reduce upper limb clothing as much as possible, which leads to low comfort during rehabilitation training. If the air-conditioning system is completely relied upon, the purpose of increasing the local temperature of the upper limbs cannot be achieved. At the same time, by increasing the local temperature, the temperature around the upper limbs can be increased, and then the blood circulation speed of the upper limbs can be increased, thereby enhancing the rehabilitation effect.
[0051] In order to coordinate the adjustment of the oil storage mechanism and the oil drive mechanism, an oil storage tank 11 for storing the drive fluid is installed inside the rear control cover 5, and a drive pump 12 for supplying fluid to the second annular electric control regulating cylinder 723 and the third annular electric control regulating cylinder 733 is installed inside the oil storage tank 11.
[0052] The driving pump 12 draws out the oil inside the oil storage tank 11, and uses the oil pipeline built into the flip adjusting arm 712 and the second flip arm 724 to supply oil to the second annular electric-controlled adjusting cylinder 723 and the third annular electric-controlled adjusting cylinder 733, and then adjusts the direction of the inlet and outlet oil through the reversing valves installed at both ends of the second annular electric-controlled adjusting cylinder 723 and the third annular electric-controlled adjusting cylinder 733, thereby adjusting the flip angles of the second flip arm 724 and the third flip arm 734.
[0053] The second annular electrically-controlled regulating cylinder 723 and the third annular electrically-controlled regulating cylinder 733 have the same internal structure.
[0054] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
