This invention relates to the field of dexterous hand technology, and provides a dexterous hand thumb structure, a dexterous hand, and a robot. The dexterous hand thumb structure includes a palm drive unit, a first deceleration unit, and a thumb module. By using the palm drive unit and the first deceleration unit as drive components for the metacarpophalangeal joint, the entire thumb module can achieve palmar lateral swinging motion. At the same time, by setting a bending drive unit in the thumb metacarpal joint, the rotation of the CMC joint is controlled by the bending drive unit, thereby enabling the thumb metacarpal joint to swing while simultaneously performing rotational flexion and extension movements. Furthermore, the rotation axis of the thumb metacarpal joint is perpendicular to the rotation axis of the entire thumb module's swinging motion, and the entire movement process is independent and compact. This allows for independent control of thumb bending and palmar movement within a limited space, achieving more precise dexterous hand motion control.

The utility model relates to the field of warm -keeping technology, concretely is a kind of heating gloves based on ergonomics, including glove lining, the heating wire is fixedly connected with in the palm side of glove lining, the heating wire includes by the distribution of large metacarpal segment in the inside of large metacarpal from the rima glottidis, the beneficial effect of the present device is: utilize the concave structure of human palm, distribute in palm concave place by hypothenar segment, large metacarpal segment and phalangeal joint avoidance section, avoid electric heating wire compression muscle and metacarpal joint while ensuring heating and keeping warm;By metacarpal joint avoidance return section and metacarpal joint avoidance section, avoid the joint protrusion of second metacarpal to fifth metacarpal and proximal phalanx;Again by phalangeal joint avoidance section along the joint of proximal phalanx and middle phalanx distribution, utilize the concave wiring formed by finger natural bending, avoid heating wire compression joint and muscle, finally realize finger heating while improving comfort.

This application belongs to the field of robotics technology, and the embodiments provide a dexterous hand and a robot. The dexterous hand includes: a palm base plate; a thumb detachably connected to the palm base plate, the thumb including a thumb drive assembly for driving flexion-extension and lateral movements, the thumb drive assembly being located within the thumb; and multiple phalanges, each phalanx including a first drive assembly, a second drive assembly, and a metacarpal bone, the first and second drive assemblies being configured to drive the phalanges to perform flexion-extension and lateral movements; wherein the first and second drive assemblies independently include a power module and a transmission module, the power module being integrated within the palm base plate, and the transmission module being integrated within the metacarpal bones. This dexterous hand has a compact structure, is lightweight, and more closely resembles the shape and size of a human hand; the five fingers adopt a modular design, allowing for individual disassembly and control, greatly facilitating installation, debugging, and maintenance, and reducing usage costs.

A dexterous hand, including a hand module, the hand module includes one or more finger units and a palm unit, wherein each finger unit includes a plurality of phalanges and one or more interphalangeal joints, wherein the palm unit includes a carpometacarpal base, one or more metacarpals, one or more carpometacarpal joints, and one or more metacarpophalangeal joint, wherein each finger unit is hinged to a respective metacarpal by a respective metacarpophalangeal joint, wherein each metacarpal is respectively connected to the carpometacarpal base, wherein each interphalangeal joint has degrees of freedom of flexion extension, wherein each metacarpophalangeal joint has degrees of freedom of flexion extension, degrees of freedom of abduction adduction and degrees of freedom of circumduction, wherein each interphalangeal joint's degrees of freedom of flexion extension, each metacarpophalangeal joint's degrees of freedom of flexion extension, each metacarpophalangeal joint's degrees of freedom of abduction adduction are driven by different actuators.

The present invention relates to a brace configured to be worn on the forearm and hand of a human being to stabilize the wrist joint, and comprises a rigid body having an exoskeleton surrounding an elongated core. [Solution] The rigid body 12 comprises a metacarpal section 18 having (i) a ring-shaped or ring-segment-shaped thumb-holding section 20 configured to receive the thumb of a human hand, a palm section 22 configured to engage with the palm of a human hand, and an ulnar section 24 configured to wrap around the human hand from the palm side to the dorsal side; (ii) an elongated intermediate section 26 configured to engage with the medial or lateral side of a human forearm; and (iii) a forearm section 28 configured to wrap around the human forearm from the ventral side to the dorsal side.
