Background technology
Along with the progress in epoch, the development of artificial limb is also more and more faster, prosthesis technique is through long-run development, there is technology of doing evil through another person very ripe and a large amount of production of grip function, to upper limb incompleteness person install this functional hand most typical be towedly to do evil through another person, myoelectricity controls that formula is done evil through another person, Electronic control formula is done evil through another person, this a few class has been done evil through another person common feature: five fingers only have one degree of freedom, namely thumb refer to relative to other four to open, closed.This single action can not meet the demand of patient, therefore artificial limb further develops again and drives from by single motor, five fingers can only simply link, simple can only be done and close function, to by more than five or five Electric Machine Control, five fingers have joint and can single movements, can also combinative movement, the action of various complexity can be carried out, functionally closer to human normal hands.This doing evil through another person of the five fingers energy independently moving is commonly called as bionic hand.Current this bionic hand thumb is generally can only referring to relative to four move in direction of motion planes, referring to that in plane of movement, action can only passively be pulled perpendicular to four, not very convenient on using.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of bionic hand thumb, thumb can referring to relative to four move in direction of motion planes, again can perpendicular to action in four finger plane of movement, and convenient patient is to the control of doing evil through another person.
The technical solution of the utility model is achieved in the following ways: a kind of electronic two-dimentional bionic hand thumb, shell is referred to by thumb, reducing motor, thumb worm screw case, thumb worm screw, thumb worm gear, thumb support shaft, rotary worm, thumb rotating shaft, rotation of worm gear, rotational delay motor, rotary worm case forms, reducing motor is connected with thumb worm screw case and rotary worm case respectively by screw thread with rotational delay motor, reducing motor is connected with thumb worm screw and rotary worm respectively by motor contact with the output shaft of rotational delay motor, it is characterized in that: described reducing motor drives thumb worm screw and the engagement of thumb worm gear, thumb worm screw is circled around thumb worm-wheel shaft, thus drive thumb to refer to that shell rotates around thumb worm-wheel shaft, rotational delay driven by motor rotary worm and rotation of worm gear engagement, rotation of worm gear is circled around thumb rotating shaft, drive thumb support shaft at the move in plane referring to the direction of motion perpendicular to four.
Described thumb worm screw case has bearing saddle bore I, jump-ring slot I and screwed hole I, and thumb worm screw two ends are arranged on thumb worm screw case by bearing and jump ring; Described rotary worm case has bearing saddle bore II and jump-ring slot II and screwed hole II, and rotary worm two ends are arranged on rotary worm case by bearing and jump ring.
Described thumb support shaft is connected for overall with thumb worm gear by pin, the plane of thumb support shaft has mounting hole, thumb worm screw case circles around thumb worm gear, and thumb support shaft is connected to form one by circular hole and thumb rotating shaft again.
Described thumb support shaft and thumb rotating shaft are linked into an integrated entity by rotating hole, and thumb rotating shaft is by loading in rotary worm case after keyway and rotation of worm gear assembling.
This utility model, structure is simple, and adjustable length is easy for installation, the electronic two-dimentional bionic hand thumb of applicable not homochirality, lighter in weight.
