A height reach device includes a support frame and a main body. The support frame includes a first vertically erected component, a second component connected to the lower end of the first component and inclined upwards away from the first component, and a third component supported between the first and second components. The main body includes an integrally formed touch portion and a connecting portion. The first component connects to an external supporting facade. The second component has a slide rail extending along its inclined direction. The connecting portion is slidably connected to the slide rail. The touch portion is located on the side of the connecting portion away from the second component. When the connecting portion moves relative to the slide rail, the height of the touch portion and the distance between the touch portion and the first component can be changed. Because the height of the touch portion and the distance between the touch portion and the supporting facade are adjustable, this height reach device can meet the training needs of people at different heights and reduce the probability of people hitting the supporting facade, ensuring safe use.

This utility model provides an adjustable high jump training device for physical education, relating to the field of physical education equipment technology. It includes a base, with adjustment mechanisms symmetrically installed on the top of the base near the left and right sides. A drive assembly is installed inside the base. The adjustment mechanism includes a fixed column welded to the top of the base, and an adjustment assembly installed inside the fixed column. A crossbar assembly is installed inside the adjustment assembly and located inside the fixed column. A reset assembly is installed around the fixed column. Through the coordinated use of the drive assembly, fixed column, and adjustment assembly, the height of the stop lever can be adjusted. Through the coordinated use of a turntable, push plate, fixed plate, rotating shaft, and magnet, the stop lever can be quickly pushed inward after use, bringing the inner ends of the two stop levers close together and completing the connection. Compared to traditional training devices, this greatly improves ease of use and effectively enhances practicality.

This invention relates to the field of sports equipment control technology, and discloses a fully automatic lifting and lowering control system and method for a gymnastics vault. The system includes a mechanical lifting and locking mechanism and a fully automatic closed-loop control system. The mechanical lifting and locking mechanism has a fixed drive unit. The fully automatic closed-loop control system includes a control unit, a detection and feedback unit, and a drive execution unit. The detection and feedback unit collects the vault's operating data and feeds it back to the control unit. The control unit uses a cascade closed-loop control strategy of position loop, speed loop, and current loop to generate drive commands. The drive execution unit adjusts the operating parameters of the drive unit, and the drive unit provides power to the lifting and lowering execution unit to drive the vault to perform linear motion. This invention shortens the time to reach the target height position through the cascade control strategy, improves the accuracy of height difference calculation, and, combined with a time window filtering anti-shake mechanism, avoids mis-locking actions and prevents the vault from slipping due to gravity.

The application discloses an intelligent jumping test analysis method and system based on computer vision and multi-modal data fusion, relates to the technical field of human motion analysis, and comprises the following steps: individual modeling is performed on a subject before testing, individualized limb segment parameters, visual quality baseline and dynamic characteristic benchmark are obtained, multi-view visual image streams and inertial measurement data are collected in formal testing, after three-dimensional reconstruction and inertial calculation, the jumping phase boundary is determined based on the individual dynamic characteristic benchmark, and three-dimensional joint trajectory is output, kinematic parameters and ground reaction force are calculated, the phase boundary is iteratively corrected through dynamic reverse checking closed loop, and the jumping ability evaluation result is output. Through the synergistic effect of individual modeling driven full-process self-adaptation, phase perception multi-modal fusion and dynamic reverse checking closed loop, the precision and robustness of the jumping test analysis are improved, and the applicability to subjects with different body types and motion abilities is enhanced.
