Problems solved by technology

[0003] The purpose of the present invention is to solve the disadvantages of the existing force feedback data gloves, such as high price, complex system, and difficult maintenance, and proposes a combination of an external potentiometer and a joint bidirectional active drive device, which can detect the motion information of human hand joints. At the same time, it also converts the feedback force sensory information into a force or torque that directly acts on the human hand, which greatly simplifies the complex force feedback data glove system

specific Embodiment approach 1

[0012] Specific implementation mode one: image 3 As shown, the data glove thumb distal joint detection device includes a driving part 111, and the driving part 111 includes a motor 40 and a clutch device. The extension spring 43 and the clutch device cover 44 are composed of the friction plate slide bar 42 and the shaft of the motor 40, and the two clutch device friction plates 41 are inserted into the two ends of the friction plate slide bar 42 respectively, and between the two clutch device friction plates 41 A return extension spring 43 is connected, and the clutch cover 44 is inserted into the shaft of the motor 40. The clutch cover 44 is in sliding contact with the shaft of the motor 40, and the clutch cover 44 is provided with transmission gears. Action implementation process: when the rotation speed of the motor 40 is higher than a certain value, the two friction plates 41 of the clutch device overcome the pulling force of the return tension spring 43 and slide to the ...

specific Embodiment approach 2

[0013] Specific implementation mode two: as figure 1 , figure 2 and image 3 As shown, the data glove distal thumb joint detection device includes a thumb distal knuckle base 3 , a thumb proximal knuckle base 4 , a driving component 111 , a potentiometer 18 and a reduction gear set 60 . Described thumb far knuckle base 3 is fixed on the thumb far knuckle position of people's hand, and one end of thumb far knuckle base 3 is cylindrical around the thumb far knuckle, and the other end is hemispherical, and the longitudinal section of the whole base is It is "U" shaped, with the opening facing the interphalangeal joint (DIP) of the thumb, and a sliding groove is provided at the position where the base is located on the outer side of the distal knuckle of the thumb. The thumb far knuckle base 3 and the thumb proximal knuckle base 4 are hinged by a rocker arm 25, one end of the rocker arm 25 is embedded in the chute of the thumb far knuckle base 3, and is limited by a screw 24. ...

Abstract

The invention discloses a thumb far-end joint detection device for a data glove and relates to a device for detecting the movement state of fingers of a hand and feeding back the force borne by corresponding finger joints of the hand. By the adoption of the thumb far-end joint detection device for the data glove, the defects that according to an existing force feedback device, a joint measurement mechanism and a force feedback mechanism are separated, a system is complicated, the structure is complicated, maintenance is difficult, bidirectional active driving cannot be achieved, and the price is high are overcome. A joint detection mechanism and a force feedback mechanism are integrated, and a unique connection way and ingenious joint measurement point arrangement are adopted, so that when an operator uses the device, the detected finger can be kept flexible to the maximum extent; the movement state can be accurately detected so that the corresponding finger joint of the controlled hand and the corresponding finger joint of the operator can move cooperatively and consistently, the stress condition of the hand in the specific working environment can be fed back to the operator, and accordingly virtual reality or the sense of immediacy of remote control is enhanced.

Description

technical field [0001] The invention relates to a data glove which detects the movement state of human fingers and has the function of two-way feedback force. Background technique [0002] Due to the development of science and technology, robots are gradually being used in an increasing range. As a reliable and mature robot, teleoperation robots are widely used in various dangerous, complex and inaccessible environments. It uses a very reliable control method, which is directly controlled by the operator's instructions. As the tasks performed by teleoperated robots become more and more complex, people put forward higher requirements for their flexibility while pursuing reliability, and it is necessary to implement teleoperation on complex manipulators to control the movement of multiple fingers of the manipulator. Multiple joints move together to achieve specific functions, which requires the use of data gloves, and the data glove with force feedback function is the most ef...
