Embodiment 1

[0036] Embodiment 1, a mechanism that can realize precise gait adjustment, includes a frame 1, a trajectory generation mechanism and a trajectory adjustment mechanism with an adjustable connecting rod, wherein the trajectory generation mechanism includes a crank 2 and a connecting rod 3, and the crank 2 One end is hinged with the frame 1, and the other end is hinged with the connecting rod 3 to form a revolving pair.

[0037] The middle part of the adjustable connecting rod 4 of the trajectory adjustment mechanism is hinged with the connecting rod 3 to form a revolving pair. The hinge point of the adjustable connecting rod 4 and the connecting rod 3 is the input point of the gait trajectory. Forming a movable and rotatable connection, the end of the adjustable link 4 can adjustably enlarge or reduce the gait trajectory.

[0038] In more detail, the trajectory generation mechanism is composed of a crank-rocker mechanism installed on the frame. The crank-rocker mechanism include...

Abstract

The invention discloses a mechanism capable of realizing accurate gait adjustment, which comprises a rack, a track generation mechanism and a track adjustment mechanism with an adjustable connecting rod, wherein the track generation mechanism comprises a crank and a connecting rod; one end of the crank is hinged to the rack, and the other end of the crank is hinged to the connecting rod; the middle of the adjustable connecting rod of the track adjustment mechanism is hinged to the connecting rod; the hinged point of the adjustable connecting rod and the connecting rod is a gait track input point; the head end of the adjustable connecting rod is movably and rotatably connected to the rack; and the tail end of the adjustable connecting rod can adjustably enlarge or narrow a gait track. According to the mechanism, the combination of a crank rocker and the track adjustment mechanism with the adjustable connecting rod is adopted, so that accurate human body gait track movement is achieved,the training mode of the circumferential or oval or similar human body gait movement track is changed, the accurate foot gait track during walking of a person is met, the size of the gait track is adjustable, the adjustment method is simple, the performance is stable, the use requirements of users with different heights are met.

Description

Technical field: [0001] The invention relates to gait training equipment, in particular to a mechanism and a training device capable of realizing precise gait adjustment. Background technique: [0002] At present, physical training has become a research hotspot. Many training equipment widely used in the market only provide simple curve or straight trajectory, including elliptical machines and some foot-driven equipment, which are characterized by a low degree of fit between the motion trajectory and the human gait trajectory. 1. The training mode is single, and the user cannot achieve a good training effect. [0003] The single-degree-of-freedom trainer has a simple structure, but its movement form is single, and it cannot provide a variety of gait trajectory training methods and cannot accurately adjust the size of the gait trajectory. Although it is inclusive, it is difficult to meet the personalized and precise training requirements of different users. [0004] The res...
