Abstract

The invention relates to a size-adjustable variable-rigidity force feedback glove which comprises a thumb mechanism assembly, a four-finger mechanism assembly and a base connecting assembly. The thumbmechanism assembly and the four-finger mechanism assembly are connected together through the base connecting assembly, each of the thumb mechanism assembly and the four-finger mechanism assembly comprises a base connecting unit, a variable stiffness unit, a free / constraint state switching unit and a fingertip connecting unit, and the switching between a free space state and a constraint space state can be realized. The variable-rigidity force feedback glove overcomes the defect that the existing force feedback equipment is lower in simulative rigidity, reduces the fatigue feeling of a user wearing the glove for a long time, better conforms to the physiological principle of the human hands, can adjust the size to adapt to the sizes of the hands of different users while ensuring light weight, and enhances the universality of the equipment.

Description

technical field [0001] The invention relates to a wearable force feedback device, in particular to a force feedback glove with adjustable size and variable stiffness. Background technique [0002] The application of force feedback gloves has changed the way people interact with the virtual environment, allowing users to obtain feedback information from the virtual world through the dexterous operation and sensitive perception of the hands, which greatly enhances the sense of interactive immersion. Pneumatic feedback gloves have the advantages of light weight and large range of motion, but the low response frequency of the pneumatic transmission system makes it difficult for users to dynamically perceive the feedback information of the virtual world in real time; at the same time, complex and bulky power transmission systems such as pneumatic pumps and pressure reducing valves Limits the portability of the device. Force feedback gloves designed based on materials such as sha...
