Embodiment Construction

[0049] Specific implementation plan

[0050] Hereinafter, the present invention will be further described in detail through specific embodiments in conjunction with the drawings.

[0051] Such as figure 1 , 2 As shown, in this embodiment, S1 is a foot board device, which includes an S11 foot board pad and a connecting part between the S12 foot board pad and the leg support, and S12 does not move relative to S11. S11 can be made into an arc to clamp the user's foot or shoe, and then equipped with a flexible fixing device to completely fix the user's foot or shoe on the foot pad, that is, the S11 is integrally sheathed or tied to the user's foot by the flexible fixing device Or on shoes. In this way, when the mechanical exoskeleton drives the foot pad to move, the force of the user's foot or shoe has a better effect. The distance measuring sensor can be fixed on the S12 to measure the distance between the forward and the obstacle or the distance between the downward and the ground....

Abstract

The invention discloses a power-assisted mechanical exoskeleton system with an automatic obstacle-avoiding function and a footing-losing-preventing function. According to the system, distance measuring sensors for measuring the distances away from the surrounding obstacle and the ground are mounted on foot sole devices, used for measuring the distance between the feet of a user and the surrounding obstacle and the distance between the feet of the user and the ground in real time when the user walks. A gait analysis module in the system is used for predicting the movement locus of each foot sole device according to the conventional gait data of the user, and the distance away from the surrounding obstacle and the height of the surrounding obstacle, so that the situation that the obstacle hinders the walking of the user is avoided. Meanwhile, according to the distance away from the pedaled ground and the predicted movement locus, the possibly occurring footing losing condition of the user can be judged, and the exoskeleton system is guided to carry out the corresponding actions, so that the harm caused by the footing losing to the user is reduced. The system further comprises a waistband provided with air bag restraint systems, when the pressure of the feet of the user is very small, and after the whole body or exoskeleton of user has the rotation unbalance exceeding a certain angle under the condition, the corresponding air bag restraint system is opened according to the rotation direction, so that the fall injury caused to the user can be prevented.

Description

Technical field [0001] The patent of the present invention belongs to the field of mechanical exoskeleton, and specifically relates to a mechanical exoskeleton system that can automatically avoid obstacles and prevent stepping on air. It is especially aimed at the elderly and people with limited mobility, and has a certain anti-fall function. Background technique [0002] The mechanical exoskeleton system is a wearable machine that can enhance the human body's capabilities. It can provide protection, additional power or ability, and enhance human body functions. Existing exoskeleton products are mainly for the military and medical fields, especially for the weight, speed and strength of soldiers, and the walking of disabled people with paralyzed legs. Civilian products have also done a lot of work on enhancing physical strength and maintaining the balance of the mechanical structure. Therefore, supporting the body, carrying heavy objects, following the body, driving the movement...
