A back includes an integrated articulating back frame and a back support. The back frame has a lower segment pivoted to a chair control, an upper segment for thoracic support, and links forming a four-bar linkage with the upper and lower segments, with a joint being formed at the lumbar region. The back support is stretchable in limited directions to accommodate shape change in the articulating back frame but to provide adequate support to a seated user. Upon receiving a rearward pressure on the lumbar joint, the back frame itself changes shape. The pivot locations in the four bar linkage create a mechanism that simultaneously controls rotational and translational movement of the upper segment during flexure of the lumbar. The back frame is close to the back support to provide significant design flexibility, but permit substantial lumbar flexure. Various back supports are contemplated that accommodate articulation of the back frame.

The invention discloses a quadruped bionic system based on the pneumatic muscle. The bionic system uses the pneumatic muscle to simulate the muscle of a quadruped to drive the neck, fore legs, thoracic joint, lumbar joint and hind legs to move, particularly simulate the pneumatic muscle having the actions of the sternocephalicus muscle, brachiocephalic muscle, musculi splenius, superficialis chestmuscle, arm triceps muscle, wrist radial extensor muscle, wrist oblique extensor muscle, wrist ulnar lateral flexor muscle, wrist radial flexor muscle and the like to drive the neck and the fore legsto flex, fold, unfold and rotate, simulate the posterior serratus muscle and the latissimus dorsi muscle to drive the thoracic joint to do lateral bending, pitching and circular rotation motions, simulate the internal oblique muscle and the medius arm muscle to drive the lumbar joint to do lateral bending, pitching and circular rotation motions, and simulate the pneumatic muscle having the actions of tensor fascia lata, quadriceps femoris, semitendinosus, tibialis anterior, peroneal longus, gastrocnemius and the like to drive the hind legs to flex, fold and unfold. According to the quadrupedbionic system based on the pneumatic muscle, the pneumatic muscle is used for driving, the quadruped bionic system based on the pneumatic muscle has the beneficial effects of being compact in structure, clean and good in explosion-proof performance and can be used for teaching and demonstration.

The invention discloses a human waist joint simulation system based on the series-parallel connection of pneumatic muscles and an air cylinder. The pneumatic muscles simulating the human muscles and the thin-walled air cylinder drive the ribs and the vertebrae to move, and the system has the function of completely simulating the movement of the human waist joints. The human waist joint simulationsystem is mainly composed of the pelvis, the ribs, the vertebra, the thin-walled air cylinder, the pneumatic muscles and the like, and the pneumatic muscles simulating the effects of the latissimus dorsi muscles, the obliquus externus abdominis muscles, the rectus abdominis muscles, the erector spinae muscles and the like and the thin-walled air cylinder drive the rib and vertebral joints to rotate around a vertical axis, a sagittal axis and a coronal axis and make linear movement in the three directions. The system is driven by the pneumatic muscles and the thin-walled air cylinder, has the advantages of compact structure, multiple degrees of freedom and good explosion-proof performance, and can be used for medical diagnosis, teaching demonstration, exhibition and the like.

The invention discloses a single-leg device of a double parallel four-bar transmission mechanism and a six-wheel legged robot. The single-leg device of the double parallel four-bar transmission mechanism includes a base joint part, a thigh part and a lower leg part, and has three degrees of freedom. The driving of the knee joint is realized by a double parallel four-bar mechanism, which reduces the mass of the calf and at the same time enables the knee joint to obtain a range of motion greater than 180°. The hip joint drive motor and knee joint drive motor are embedded inside the thigh parts to increase the range of motion of the lumbar joint. Modular driving wheel components can be added to the single-leg unit as required. The six-wheel-legged robot using the single-leg device of the double parallel four-bar transmission mechanism can realize leg-like movement or wheel-like movement, and perform simple operations. You can continue to move immediately if you need to reverse the station.

The invention relates to a medicinal wine for treating joint pain, which is refined by traditional soaking process by using 9 kinds of precious Chinese medicinal materials including tortoise shell, antler, ginseng, medlar, eucommia ulmoides, cassia twig, drynaria drynariae, Qiannianjian and mulberry branch. It has the effects of invigorating orifices, nourishing yin and yang, and nourishing blood and kidney. It has obvious analgesic and curative effects on joint pain, muscle and bone pain, frozen shoulder, cervical spondylitis, and cold pain caused by overwork. It is also effective for lumbar disc herniation, It has a good therapeutic effect on lumbar posterior joint disorder, sciatic nerve injury and muscular atrophy.

The invention discloses a four-foot multi-direction movement robot system based on an air cylinder. The air cylinder drives leg joints and waist joints of a four-foot robot to move, the robot has a function of moving in a transverse direction and a longitudinal direction, and has a function of moving in a direction at a certain angle with the transverse direction and the longitudinal direction. The four-foot multi-direction movement robot for the air cylinder is mainly composed of supporting legs, fixing plates, waist joint air cylinders, vertebrae, a supporting frame, a swinging air cylinder,supporting leg air cylinders, a rod end joint bearing and connecting pieces. The swinging air cylinder and the supporting leg air cylinders drive the four supporting legs of the four-foot robot to realize the free switching of transverse angle, longitudinal angle and other angles; and the waist joint air cylinder and the vertebrae are adjusted according to the actual movement requirement of the four-foot robot so as to meet the requirements of different movement directions of the four-foot robot to the posture of the waist joint. The four-foot robot driven by the air cylinder has the characteristics that flexibility is good, movement direction is multiple, the movement direction can be freely switched, and the robot can be applied to the fields of field work, obstacle-crossing and explosion-proof, military load-bearing transportation and the like.
