Embodiment

[0034] Such as figure 1 , figure 2 shown. The multi-degree-of-freedom robotic bionic hand of the present invention includes a robotic palm base 3 and five fingers connected to the robotic palm base 3, and these five fingers sequentially include thumb 1-1, index finger 1-2, middle finger 1-3, and ring finger 1- 4. Little fingers 1-5; the exterior of the robot palm base 3 is covered with a shell 2, which is used to cover the internal motor and transmission components.

[0035] The four fingers of index finger 1-2, middle finger 1-3, ring finger 1-4 and little finger 1-5 have the same structure, and each finger has two degrees of freedom of flexion and extension.

[0036] Such as image 3 , Figure 4 shown. Each finger in these four fingers comprises a housing 6 , a root 9 , a fingertip 10 , and a transmission link 11 on which a motor 7 and a transmission worm gear 8 are installed.

[0037] Such as image 3 , Figure 4 shown. One end of the transmission worm gear 8 is c...

Abstract

The invention discloses a mechanical simulated hand with multi-degree of freedom. The mechanical simulated hand comprises five fingers including a thumb, an index finger, a middle finger, a ring finger and a little finger, and the five fingers are connected with a base mechanical palm. The index finger, the middle finger, the ring finger and the little finger are identical in structure and provided with two bending and stretching degrees of freedom, and each of them comprises a housing, a finger root, a finger tip and a transmission connecting rod; a motor and a transmission worm gear worm are mounted in the housing; one end of the transmission worm gear worm is connected with an output shaft of the motor, the other end of the transmission worm gear worm is rotationally connected with one end of the finger root, and the other end of the finger root is rotationally connected with the rear section of the finger tip; one end of the transmission connecting rod is rotationally connected with the housing, and the other end of the transmission connecting rod is rotationally connected with the inner side of the rear section of the finger tip. The mechanical simulated hand with multi-degree of freedom is simple and convenient in technical operation, and abundance finger motion abilities such as clenching, key and ball holding can be provided for patients in limited space by the aid of computer control.

Description

technical field [0001] The invention relates to a manipulator in the field of medical rehabilitation equipment, in particular to a multi-degree-of-freedom machine bionic hand. Background technique [0002] Rehabilitation medicine is an emerging discipline that emerged in the middle of the 20th century. Its purpose is to reduce and eliminate the dysfunction of patients through various means such as physical therapy, exercise therapy, life training, skill training, speech training and psychological counseling, so as to make the remaining parts of the body function better. Get the most out of it, make up for and rebuild the patient's functional loss, and achieve the greatest possible self-care, labor and work abilities. With the increase of various natural disasters and accidents, the number of physically disabled people is also increasing year by year. For disabled people with amputations, the most common restoration measure at present is to install artificial limbs to obtain...
