Abstract
The invention discloses a palm of a two-dimensional thumb bionic hand. The palm is a basic element of the two-dimensional thumb bionic hand. Gear motor holes (6-1) and an upper plane (6-2) where a finger module is fixed are arranged in a palm body (6). The palm is characterized in that an arc (6-3) is arranged on the lower portion of the palm body (6), and the lower portion of the palm center, the front face and the back face of the palm body (6) are covered with a palm housing. The palm is simple and reliable in structure; the interior structural size of the five fingers is small, so that the palm has more space, and the overall hand type is more personalized; and the palm can be suitable for using and mounting of different hand types, smaller in weight and good in bionic effect.
Description
Technical field
The present invention relates to myoelectricity, the bionical technical field of doing evil through another person of Electronic control, specifically refer to the bionical palm at hand of a kind of practical two-dimentional thumb.
Background technology
Along with the development of science and technology, the development of upper extremity prosthesis is also maked rapid progress, myoelectric limb is driven into present being driven by multiple motor from initial by single motor, this have multiple motor-driven doing evil through another person to be commonly called as bionic hand, and function can only simply be opened from initial finger, close each finger energy single movement and combinative movement till now.Domestic and international at present much research is carried out to this doing evil through another person, and enter clinical stage, by analyzing corresponding product on the market, find structurally all also there is some defects or deficiency, the drive unit had plenty of five are pointed is arranged in finger, adopt rope to pull prosthetic finger second joint to bend by fingers and palms of doing evil through another person, prosthetic finger second joint is equipped with spring, makes prosthetic finger second joint get back to deployed position from the position of bending by elastic force; Have do evil through another person the drive unit that five are pointed to be placed on is done evil through another person in the palm, and five finger screw mandrels drive finger and palm joint, then drive second joint with connecting rod, and it is all elastic force by spring that prosthetic finger first joint and second joint open; Be that motor is placed on the back of the hand position in addition, thumb can only action before and after relative four finger directions, and left and right directions action can only passively be pulled.This several fault of construction is: one, motor be placed on finger in this structure make finger length be difficult to shorten, thumb nail-volume is larger, two, to open strength less for finger, thicker right-hand side skin can not be driven, thin and soft hand skin can only be used, three, motor is placed on the back of the hand position, make control circuit can only be placed on palm of the hand position, due to finger grip action, easily cause control circuit to damage, thumb left and right directions adopts passive pulling to be not easy to patient's use.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of this invention is to provide the bionical palm at hand of a kind of two-dimentional thumb, doing evil through another person the drive unit that five are pointed to be placed on does evil through another person in the palm, and direction, all around can Electronic control, functionally meets the instructions for use of patient further.
Technical scheme of the present invention is achieved in the following ways: the bionical palm at hand of two-dimentional thumb, for the bionical primary element at hand of two-dimentional thumb, the upper plane of reducing motor hole and fixed finger module is had in described palm, it is characterized in that: arc is arranged at the bottom of described palm, the bottom, the centre of the palm of palm, front, the back side are coated with palm case.
Described palm bottom is also provided with wrist joint, is provided with passive wrist joint or electric wrist unit as required.
The centre of the palm of described palm is provided with forefinger, middle finger, the third finger, little finger and two-dimentional thumb, and control circuit system is arranged on the palm back side of palm.
The present invention, simple and reliable for structure, five finger interior structural volume are less, make palm have more spaces, and overall hand-type is more personalized, and the use of applicable not homochirality is installed, and lighter in weight is bionical effective.
Accompanying drawing explanation
Fig. 1 is stereogram of the present invention.
Fig. 2 is two-dimentional thumb bionic hand header structure schematic diagram.
Detailed description of the invention
As shown in Figure 1, the bionical palm at hand of two dimension thumb, for the bionical primary element at hand of two-dimentional thumb, the upper plane 6-2 of reducing motor hole 6-1 and fixed finger module is had in described palm 6, arc 6-3 is arranged at the bottom of described palm 1, two dimension thumb installs the bottom, the centre of the palm of palm 6, and the front of palm 6, the back side are coated with palm case.Described palm 6 bottom is also provided with wrist joint 7, is provided with passive wrist joint or electric wrist unit as required.
Being known by Fig. 2, is two-dimentional thumb bionic hand header structure schematic diagram.The centre of the palm of described palm 6 is provided with forefinger 1, middle finger 2, the third finger, little finger 3 and two-dimentional thumb 5 and wrist joint 7, and control circuit system is arranged on the palm back side of palm 1.
In order to prevent finger from occurring tong cover phenomenon in BENDING PROCESS, being all designed to convex structure at the first articulations digitorum manus of forefinger, middle finger, third finger and little finger and the second articulations digitorum manus place, avoiding occurring that tong overlaps phenomenon.The worm gear of each finger is provided with spacing hole, controls the angle of articulations digitorum manus opening and closing.
Structure of the present invention is simple, overcomes the deficiency of bionic hand in the past, adopts bar linkage structure, make finger opening and closing have identical moment, finger length can change length according to human finger, has more biomimetic type from appearance and modeling, each finger adopts modularized design, is convenient to assembling and maintenance.
In this description, the present invention has contrasted its specific embodiment and has made specific descriptions, but, still can make various amendment and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, description and accompanying drawing are regarded in an illustrative, rather than a restrictive.
