The utility model provides a human mechanics waist protection plate which comprises a first backup plate and elastic fixing structures arranged on the two sides of the bottom of the first backup plate. The inserting groove is formed in the top of the second backup plate and connected with the elastic fixing structure in a clamped mode, and the clamping openings are formed in the two side faces of the second backup plate and communicated with the inserting groove. The massage structure is arranged at one end of the second backup plate and used for massaging and relieving the lumbar vertebra of the user; the massage structure comprises an arc-shaped backup plate, pivoting rings arranged on the two sides of the arc-shaped backup plate and a bent rod rotationally arranged between the two pivoting rings. According to the waist protection plate, the comfort level of a user is improved, ventilation and breathability are enhanced through the arrangement of the ventilation grooves, the use experience is further improved, in addition, the user can conveniently clean and replace parts of the waist protection plate through the detachable design, meanwhile, the massage structure can effectively relieve fatigue of waist muscles, and the use experience of the user is improved.

The present application relates to a leg rest position adjustment process of Braun-type orthopedic traction, which comprises the following steps: S1, preliminary resting; S2, support position adjustment; S3, construction of rehabilitation information base. One aspect of the present application is based on the linkage adjustment of the angle, height and relative spacing between support points to form an angle leg rest support in line with human mechanics, which not only reduces the difficulty of patient posture adjustment and the difficulty of medical staff operation, but also greatly reduces the risk of limb injury, body position discomfort, muscle tension, pressure sores and other complications caused by traction, and also reduces the possibility of causing deformity healing or delayed healing rate. The other aspect is based on a health-related information system to collect and analyze data to obtain the reference parameters close to the force line of different lower limb leg rest positions, thereby constructing a traction closed loop of precise execution-data feedback-continuous optimization.

This invention discloses a rehabilitation exercise device and method for the elderly, relating to the field of rehabilitation equipment technology. It includes a support rod, an arc-shaped plate mounted on the upper part of the support rod, a movable rod rotatably connected to the side of the arc-shaped plate, a second sliding block slidably disposed inside the movable rod, a tension mechanism jointly installed between the second sliding block and the arc-shaped plate, a handle mounted at the bottom of the movable rod, and a variable component jointly disposed between the support rod and the movable rod. The variable component includes a sliding plate slidably disposed above the second sliding block, a pressure block mounted at the bottom of the sliding plate, a compression rod slidably disposed on the inner side, and a movable plate slidably disposed above the compression rod. By setting the variable component, this invention can adjust the difficulty by changing the connection position between the tension mechanism and the movable rod in real time during each exercise session. This results in subtle changes in training difficulty from small to large during each exercise session, matching the human biomechanical curve, applying maximum load at the strongest muscle angle, and improving training efficiency.

The embodiment of the application belongs to the technical field of flexible body mechanics analysis, and relates to a surface force solving method and a model training method and device based on a flexible body. The surface force solving method of the flexible body comprises the following steps: obtaining a current measurement displacement value; establishing an optimization objective function based on the current measurement displacement value; obtaining an optimization initial value by combining a preset initial value with a model based on the current measurement displacement value; the optimization initial value comprises an unknown node displacement initial value and a surface force initial value of an unknown node; and the surface force is obtained by optimizing the optimization objective function based on the optimization initial value. The technical scheme adopted by the application can improve the efficiency of force surface force solving.
