Abstract

The invention discloses a wearable device for detecting positional deviation, relates to a device for detecting the positional deviation between a wearer and the wearable device and aims to solve the problems that according to an existing method for detecting the positional deviation of the wearable device, because interaction force exists between the human body and the wearable device in the horizontal direction and the vertical direction, measuring results are confused, precision is poor and the wearable device is poor in comfort. The wearable device comprises a binding mechanism, a positional deviation detection mechanism and a sliding mechanism. The two ends of a sliding plate are connected with binding plates respectively, and horizontally-arranged first supporting shafts are arranged at the upper end and the lower end of the sliding plate in a penetrating mode respectively; the two ends of each first supporting shaft are connected to two connecting plates respectively, two baffles are attached to the connecting plates, two rubber columns are arranged on the faces of the two connecting plates in a penetrating mode respectively, and a thin film pressure sensor is installed on the face, attached to the corresponding baffle, of one connecting plate. The wearable device is used for detecting the positional deviation between the wearer and the wearable device.

Description

technical field [0001] The invention relates to a device for detecting position deviation between a wearer and a wearable device, which belongs to the technical field of robots. Background technique [0002] Power-assisted robots used to help the human body bear loads and limb rehabilitation equipment used for medical treatment have received attention in recent years, and have achieved rapid development, with more and more products coming out. They are essentially a wearable device. However, there is no special research on the binding device that has an important impact on wearing comfort and convenience. The position deviation is detected by the interaction force, and then the movement of the device is controlled. Because of its simplicity and convenience, it has been widely used. It can be seen that the accuracy of the interaction force directly affects the performance of the system. The traditional method of measuring the interaction force between the device and the hum...
