Embodiment 1

[0040] Such as Figure 1 to Figure 8As shown, the present invention provides a prosthetic hand support with a degree of freedom of turning the wrist, including a prosthetic hand mounting sleeve 1, a reversible wrist 3, a small arm follow-up support 2, a small arm 4, and a large arm follow-up support 5. The upper arm part 6 and the shoulder fixing part 7. The prosthetic hand mounting sleeve 1 is connected with the existing prosthetic hand, especially, different prosthetic hand mounting sleeve 1 designs can be carried out according to different prosthetic hands, not limited to the form shown in the present invention.

[0041] The reversible wrist 3 is composed of a terminal link 8, a pair of moving links 9, a driving link 10, a wrist housing 11, a forearm connector 12, a transmission support 13, a driven gear 15, a transmission shaft 16, a driving Gear 17, travel switch 18, drive motor 19 form. The lower shaft end of the prosthetic hand mounting sleeve 1 is installed in the ho...

Embodiment 2

[0061] A prosthetic hand support with the degree of freedom of wrist rotation, comprising a prosthetic hand installation sleeve 1, a reversible wrist 3, a small arm 4, a large arm 6 and a shoulder fixing part 7 connected in sequence, and the reversible wrist 3 A forearm follow-up support 2 is provided, and a large arm follow-up support 5 is provided on the big arm portion 6 .

[0062] Among them, the reversible wrist 3 includes a transmission support 13 that is rotatably connected to the end of the prosthetic hand mounting sleeve 1, a wrist housing 11 arranged on the transmission support 13, and a parallelogram set on the wrist housing 11. The connecting rod mechanism, the forearm connector 12 arranged at the end of the wrist housing 11, and the motor drive mechanism arranged inside the wrist housing 11, the prosthetic hand mounting sleeve 1 is connected to the motor drive mechanism through a parallelogram linkage mechanism , the forearm follower support 2 is connected with th...

Abstract

The invention relates to a prosthetic hand support with wrist overturning freedom degree and application thereof, the prosthetic hand support comprises a prosthetic hand mounting sleeve, a turnover wrist part, a forearm part, a big arm part and a shoulder fixing part which are connected in sequence, the turnover wrist part is provided with a forearm follow-up support, and the big arm part is provided with a big arm follow-up support. During application, the prosthetic hand needing to be mounted is fixed in the prosthetic hand mounting sleeve, the prosthetic hand mounting sleeve is driven by the turnover wrist part to perform turnover motion, and then the prosthetic hand is driven to turn over to a preset grabbing position. Compared with the prior art, the technical problems that in the prior art, the degree of freedom of the prosthetic hand is insufficient, the wearing experience of the prosthetic hand is poor, and the burden of a user is heavy are solved, the wearing experience of the user can be improved, and the using burden of the prosthetic hand is relieved.

Description

technical field [0001] The invention belongs to the technical field of prosthetics, and relates to a prosthetic hand support with a degree of freedom of turning the wrist and an application thereof, which is suitable for existing prosthetic hand products and is a function supplement and expansion thereof. Background technique [0002] The upper limb of the human body is an important part of the human body. The forearm and hand play a very important role in daily life. If this part of the limb is lost due to force majeure, a prosthetic limb is needed to achieve daily motor function and appearance. Picking of items. [0003] Due to cost or shape limitations, existing prosthetic hands on the market often only have a grasping function or a single-degree-of-freedom wrist rotation function, which cannot reproduce the real movement of the human upper limb forearm and hand. If the degree of freedom is increased, not only does it need to increase the installation of motors, resultin...
