A conductive slip ring for angle detection at the joint of a wearable exoskeleton

Abstract

The conductive slip ring for angle detection at the joints of the wearable exoskeleton provided by the present invention relates to the technical field of wearable devices, including a box body and a drive module, a rotor rod, a rotor module and a stator module arranged in the box body. Driven by the drive module, it has a degree of freedom to rotate relative to the box body; the rotor module includes a rotor PCB connected to the rotor rod and pogo pins and Hall sensors arranged on the rotor PCB, and the stator module includes a stator PCB, connecting The stator module outlet terminal on the stator PCB and the magnetic column connected to the box body, wherein the stator PCB is opposite and parallel to the rotor PCB, and a copper slip ring is embedded on the surface of the stator PCB close to the rotor PCB, The copper sheet slip ring is adapted to the pogo pins to form a number of conductive slip rings, and the magnetic column is adapted to the Hall sensor to form an angle detection absolute encoder; the conductive slip ring realizes the internal conduction of the structure of the present invention, and the angle detection absolute encoder is integrated in the present invention Structurally, the simplification of joint angle detection is realized.

Description

technical field [0001] The invention relates to the technical field of wearable devices, in particular to a conductive slip ring used for angle detection at joints of a wearable exoskeleton. Background technique [0002] Exoskeleton originally refers to a hard external structure that protects the soft internal organs of organisms in biology, but now exoskeleton robot refers to a type of mechanical device that imitates the state of human motion and enhances human motion ability, integrating bionics and ergonomics , worn on the outside of the human limbs, can improve people's ability in specific aspects such as walking durability and load-bearing capacity. Its application fields are very wide. In the military field, it can improve the movement flexibility, mobility, and weight-bearing capacity of soldiers; in the medical field, it can help patients with lower limb muscle weakness or other disabilities to perform rehabilitation training; in the civilian field, it can help wear ...
