Description
Technical field
This utility model relates to myoelectricity, the bionical technical field of doing evil through another person of Electronic control, specifically refers to the bionical thumb of doing evil through another person of a kind of practicality.
Background technology
Along with the progress in epoch, the development of artificial limb is also more and more faster, outstanding phase upper extremity prosthesis from initial beauty treatment formula, towedly control formula, Electronic control formula to myoelectricity; Drive from single motor, five fingers can only simply link, and can only do simple and close function, to by 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.Thisly be commonly called as bionic hand by five motor-driven doing evil through another person.Current this bionic hand thumb is generally that driving device is placed on palm, and this structure seems somewhat thick for palm, and takies the limited space of palm, is unfavorable for the layout of other element comprising control system.
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, by rotating shaft and nylon cushion frictional connection between worm gear seat and rotating seat, passively can pull thumb perpendicular to left-right rotation in thumb main motion plane, worm gear seat is provided with stopping means all around, prevent the thumb anglec of rotation from exceeding regulation requirement, in the middle part of thumb, be provided with wire casing with the sidewall of bottom, be convenient to the layout of control circuit and prevent from damaging motor lines.
The technical solution of the utility model is achieved in the following ways: a kind of bionic hand thumb, the composition of its feature comprises: thumb top, middle part, bottom, worm screw, worm gear, motor reducer, motor contact and worm gear seat, rotating seat, rotating shaft etc., thumb top is thumb finger tip, middle part is electric machine casing, bottom is worm screw block, connect respectively by screw between thumb upper, middle and lower, adopt interference fits in the middle part of thumb and between bottom and guarantee both female coaxial; It is characterized in that: described motor reducer output shaft is connected with worm screw by motor contact, worm gear is connected by worm-wheel shaft with thumb bottom worm screw case, motor reducer drives worm and worm wheel engagement, worm screw is circled around worm-wheel shaft, thus drives thumb to rotate around worm-wheel shaft.
Have bearing saddle bore up and down in described worm screw block, worm screw two ends are arranged in bearing saddle bore by bearing.
By rotating shaft and nylon cushion frictional connection between described worm gear seat and rotating seat.
This utility model structure, simple and reliable for structure, adjustable length, easy for installation, applicable not homochirality, the bionic hand thumb of lighter in weight.

Detailed description of the invention
Shown in Fig. 1, Fig. 2, bionic hand thumb of the present utility model, the composition of its feature comprises: in the middle part of thumb top 1, thumb 2, thumb bottom 3, worm gear seat 4, rotating seat 5, rotating shaft 6, nylon cushion 7, worm gear 8, worm screw 9, motor contact 10 and motor reducer 11.In the middle part of thumb top 1 and thumb 2 and thumb bottom 3 be connected by screw.
Being known by Fig. 3, Fig. 4, is in the middle part of this utility model bionic hand thumb and bionic hand thumb substructure schematic diagram.In order to ensure in the middle part of thumb the axiality requirement of 2 and thumb bottom endoporus 3-1, in the middle part of thumb, inwall 2-2 and thumb bottom endoporus 3-1 adopts interference fits, plays positioning action.Attractive in appearance in order to wear glove, be designed to arc-shaped at the lower end 3-3 of thumb bottom 3.Motor reducer 11 to be arranged in the middle part of thumb in 2 and thumb bottom endoporus 3-1, in the middle part of thumb, the outer wall of 2 is provided with holding screw clamping motor, in the middle part of thumb, 2 are provided with on Wire channel in building 2-1, thumb bottom 3 and are also provided with Wire channel in building 3-2, guarantee that thumb does not damage motor lines in BENDING PROCESS, worm screw 9 is arranged in two endoporus up and down of thumb bottom 3 by bearings at both ends, worm gear 8 and worm gear seat 4 are by tightening of rivet, and worm gear 8 is engaged by worm-wheel shaft and thumb bottom endoporus 3-4 and worm screw 9.
Being known by Fig. 5, is this utility model bionic hand thumb motor contact structural representation.On motor reducer 11 axle, the plane 10-1 of flat filament and motor contact 10 coordinates, the side 10-2 of motor contact 10 and worm screw 9 inner hole, motor reducer 11 drives worm screw 9 to rotate, and worm screw 9 and worm gear 8 engage rear drive thumb and circle around worm-wheel shaft.Worm gear seat 4, rotating seat 5 are by rotating shaft 6, nylon cushion 7 frictional connection, can be passive perpendicular to left rotation and right rotation in thumb main motion plane, thus thumb and all the other four collocation positions referred to can be changed, be convenient to various action, the tightness pulled about determining thumb by regulating the tightness of spin axis axle 6.In order to limit the position of thumb left-right and front-back, worm gear seat 4 is provided with stopping means.
In this description, this utility model has contrasted its specific embodiment and has made specific descriptions, but, still can make various amendment and conversion obviously and not deviate from spirit and scope of the present utility model.Such as thumb also can adopt electronic mode perpendicular to main motion in-plane rotates.Therefore, description and accompanying drawing are regarded in an illustrative, rather than a restrictive.
