[0021] The advantages and positive effects of the present invention are:

[0022] 1. The rehabilitation and fitness bed of the present invention is a bed designed specifically for bedridden patients or those after the disappearance of symptoms for rehabilitation and fitness exercises. This bed uses electric power to control the person on the bed to perform automatic rehabilitation exercises and fitness movements, and has the functions of preventing and controlling muscle atrophy of the bedridden person, promoting blood circulation, and fitness. Usually, this bed is a normal bed for rest and sleep. Normal people can do fitness exercises, while patients can do rehabilitation exercises at the same time. It is applicable to environments such as families, hospitals, nursing homes, and rehabilitation centers, and is a multi-functional intelligent rehabilitation and fitness bed.

[0023] 2. When the bedridden person does not need rehabilitation and fitness exercises, the rehabilitation and fitness bed of the present invention is just a bed for rest and sleep. The bed surface is provided with a mattress, and the mattress is mounted in blocks according to the various mechanisms of the bed. The block mattresses move with the movement of the various movement mechanisms. When rehabilitation and fitness exercises are needed, the head of the bed can be separated and moved away for the bedridden person to do double-arm rotation and swaying movements. Folding and widening plates are provided on both sides of the bed. When the bedridden person needs rehabilitation and fitness exercises, the widening plates of the bed flip under the bed.

[0024] 3. The lifting and swaying pillow mechanism of the present invention is designed according to the natural movement scale and angle of the human head. The pillow lifting mechanism drives the head of the bedridden person to lift the head, and the pillow swaying mechanism drives the head of the bedridden person to lift the head and swing left and right, so as to achieve the exercise of the head on the pillow.

[0025] 4. The backrest lifting mechanism of the present invention is used to drive the bedridden person to lift the back. It is set at the central part of the fitness bed frame. Usually, it is flush with the plane of the bed. When needed, it is supported by a push rod motor to the angle required by the person on the bed. People can sit on the bed and lean their backs on it, playing the role of a chair backrest.

[0026] 5. The double-shoulder horizontal rotation and elbow joint bending movement mechanism of the present invention is used to drive the double arms of the bedridden person to swing and / or drive the double arms of the bedridden person to bend. When the person on the bed needs rehabilitation or fitness exercises, the widening plates on both sides of the bed are folded under the edge of the bed. The double-shoulder horizontal rotation mechanism is used to drive the double arms to swing, and the elbow joint bending movement mechanism is used to drive the elbow joints to bend. The double-shoulder horizontal rotation and elbow joint bending movement mechanism is usually set at the two edges of the bed surface, corresponding to the positions of the two shoulders and the lengths of the arms when a person lies on the bed. Through the motor function, it drives the upper arm to rotate and the upper and lower arms to bend. The rotation mechanism enables the upper arm of the person to rotate horizontally by 0-90 degrees according to the natural angle of the human body, and through the push rod motor, the upper and lower arms of the arms are bent for exercise according to the natural angle of the person.

[0027] 6. The up-and-down and bending movement mechanism of the present invention is used to drive the legs of the bedridden person to swing up and down and / or drive the legs of the bedridden person to bend. One end of the leg movement mechanism of the up-and-down and bending movement mechanism of the legs is connected to the bed body by a movable shaft. This mechanism can drive the legs to move up and down. There is also a movable support plate designed on the leg movement mechanism, and a push rod motor is used to push the support to move and drive the legs to do bending movements.

[0028] 7. The fitness tensioner mechanism of the present invention is used to assist the bedridden person in exercising the hands or feet. The fitness pull rope devices are installed at the tail of the bed body and the end of the small arm of the arm. Usually, they are hidden in the bed body movement mechanism. There are fixed movable rings on the arm and leg movement mechanisms to prevent the arms and legs from falling off during movement. The soft ropes pass through the fixed rings to fix the upper arms and legs of the person during movement, playing a role in safely protecting the upper arms and legs and preventing accidental injuries during the rehabilitation exercise process. The surface of the bed body is decorated with a washable and replaceable soft bed surface (split type). Brief Description of the Drawings

[0066] Working principle of the shoulder horizontal rotation and elbow joint bending motion mechanism 3: There are two symmetrically arranged shoulder joint abduction arms 301, one end of each of which is hinged to the position on the fitness bed frame 1 corresponding to the shoulders. The rotating shafts 302 on the two shoulder joint abduction arms 301 are rotatably connected to the fitness bed frame 1. A bearing seat is installed between the fitness bed frame 1 and the rotating shaft 302, and the rotating shaft 302 is installed in the bearing. The driving wheel 306 on the first stepping motor 305 drives the rotating shaft 302 to rotate from 0 to 90° through the belt 307. The arms of the person lying in bed are respectively placed on the two shoulder joint abduction arms 301, and the shoulder joint abduction arms 301 drive the arms to move during the rotation process; the upper arm lifting support 308 is hinged to the position near the head side inside the shoulder joint abduction arm 301, and the third push rod motor 309 pushes the upper arm lifting support 308 to move up or down. The arm lifting support 310 is hinged to the middle position of the upper arm lifting support 308, and the fourth push rod motor 311 pushes the arm lifting support 310 to move up or down. The arms of the person lying in bed are placed on the upper arm lifting support 308 and the arm lifting support 310 inside the shoulder joint abduction arm 301 as a whole. The upper arm lifting support 308 drives the arms as a whole to lift or lower, and the arm lifting support 310 drives the partial arms to lift or lower.

[0067] Working principle of the back-lifting mechanism 4: The back-lifting support 401 is hinged to the groove in the middle of the fitness bed frame 1 through the pins at both ends. The fifth push rod motor 402 below the back-lifting support 401 is hinged to the back of the back-lifting support 401.

One end of the two two-link mechanisms 504 is fixedly connected to the middle position below the hip abduction support arms 501, and the other end of the two two-link mechanisms 504 is fixedly connected to the same rotating shaft 503. Both ends of the rotating shaft 503 are rotatably connected to the transmission shaft support 502 of the fitness bed frame 1 in the horizontal direction. The driving rod 506 hinged on the output shaft of the sixth push rod motor 505 is fixedly connected to the middle position of the rotating shaft 503. The sixth push rod motor 505 drives the rotating shaft 503 to reciprocate through the driving rod 506. The rotating shaft 503 drives the respective hip abduction support arms 501 to reciprocate swing through two sets of symmetrically arranged two-link mechanisms 504. The legs of the lying person are respectively placed on the two hip abduction support arms 501. During the process of the two hip abduction support arms 501 reciprocating swing in a staggered manner, the legs are driven to reciprocate swing. The first support rod 507 and the second support rod 508 inside the hip abduction support arm 501 support the legs of the lying person. The free end of the first support rod 507 is hinged on the hip abduction support arm 501. The free end of the second support rod 508 is slidably connected to the strip-shaped slideway hole 511 through the slide shaft 512. The seventh push rod motor 509 pushes the first support rod 507 to lift or lower, indirectly driving the knee joint of the lying person's leg to make a bending motion.
