Embodiment Construction

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being “fixed or mounted on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected or connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0028] Such as Figure 1 to Figure 4 As shown, in the embodiment provided by the present i...

Abstract

The invention relates to a hand mechanical exoskeleton device, which comprises a main body part which can be used for the wearing of four fingers and a palm; a thumb mechanism which can be used for the wearing a thumb; an attaching structure which can be attached to the thumb, wherein one end of the attaching structure is connected with the main body part, and the other end of the attaching structure is connected with the thumb mechanism; and an elastic mechanism which is arranged between the attaching structure and the main body part and can generate deformation when the thumb mechanism movesso as to exert force on the attaching structure and ensure that the attaching structure is always attached and contacted with the thumb. According to the invention, when the thumb mechanism acts, theattaching structure is stressed to be tightly attached to the thumb, so that the captured thumb motion information is consistent with the actual motion information of the thumb, and the accuracy of the hand mechanical exoskeleton device in collecting the motion information of the thumb is improved.

Description

technical field [0001] The invention relates to the field of robots, in particular to a hand mechanical exoskeleton device. Background technique [0002] In the virtual reality scene, the hand mechanical exoskeleton device is often used to capture the motion information of the human hand. The hand mechanical exoskeleton device has a five-finger mechanism that matches the five fingers of the human hand. It corresponds to the five-finger mechanism of the external mechanical exoskeleton wearable device. When the human finger moves, the corresponding sensor on the hand mechanical exoskeleton device will capture the operating angle of the human finger, realizing the capture of human hand motion information by the hand mechanical exoskeleton device. [0003] In actual use, the human thumb is more flexible than the other four fingers, and it is easy to lose fit with the hand mechanical exoskeleton device during activities, resulting in inconsistencies between the angle information...
