Embodiment Construction

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0030] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations...

Abstract

The invention provides a finger driving mechanism and a dexterous hand. The finger driving mechanism includes a first knuckle close to the palm, a second knuckle connected in rotation with the first knuckle, and a first knuckle used to drive the second knuckle to rotate. The traction rope and the driving part are provided with a first torsion spring on the rotation shaft of the first knuckle and the second knuckle, and the two ends of the first torsion spring are respectively clamped in the first knuckle and the second knuckle, The direction of the restoring force of the first torsion spring is opposite to the bending direction of the second phalanx, and one end of the first traction rope is connected with the driver, and the other end of the first traction rope stretches into the first phalanx and is wound around the second phalanx. knuckle ends. The finger driving mechanism and dexterous hand provided by the present invention can directly drive the second knuckle to rotate through the first traction rope, and the structure is simple, and the first traction rope is a flexible rope, and the user can rotate the second knuckle from the outside to prevent the user from When accidentally colliding with a finger, the finger accidentally injures the user.

Description

technical field [0001] The invention belongs to the technical field of robots, and more specifically relates to a finger driving mechanism and a dexterous hand. Background technique [0002] With the continuous development of science and technology, people's research on robots is getting deeper and deeper, and more and more repetitive tasks are done by robots. In order to allow the robot to complete finer movements, the design of the robot's hand is becoming more and more refined, which is suitable for the service industry, catering industry, etc. [0003] The dexterous hand is similar to the human hand, with more degrees of freedom and rich movements. The fingers of the current dexterous hand have multiple knuckles, and each knuckle can rotate, so the transmission structure between the knuckles is complicated, and the transmission between the knuckles is a hard transmission, that is, the movement of the fingers When the knuckles contact or collide with external objects, t...
