This utility model relates to a hand rehabilitation training tool for hemiplegic patients, including a lower palm support plate and a lifting adjustment component. The lifting adjustment component includes a lifting tube connected to the lower palm support plate and a lifting rod slidably connected to the lifting tube. An upper palm support plate is connected to the lifting rod. The technical solution of this application has the following advantages: the lower palm support plate is connected to the lifting tube, the lifting rod is slidably connected to the lifting tube, and the upper palm support plate is slidably connected to the lifting rod, thereby facilitating the adjustment of the upper and lower palm support plates. This solves the problem that existing hand support devices, such as fixed brackets and rehabilitation training trays, are mostly fixed structures, which cannot adapt to the differences in hand size and finger length among different users, resulting in inaccurate support position and affecting the effectiveness of use.

The phalangeal finger features an actuator. Various systems and methods allow for a smaller volume actuator, which in turn allows for a smaller finger and / or more space for other features of the finger. The actuator includes a motor that causes a worm gear to rotate along a fixed worm wheel. The worm gear is integral with an output shaft. The worm gear climbs along the worm wheel to cause the finger or finger segment to rotate. The arrangement of the actuator parts allows for axial forces to be transmitted in first and second directions that respectively correspond to open and close rotations of the performing finger.

The application relates to the technical field of robots, in particular to a dexterous hand and a robot to solve the problem that a dexterous hand cannot simultaneously have high flexibility and small size due to a side swing structure. The dexterous hand has independent swing functions of small fingers and / or ring fingers through at least one first side swing driving assembly and one second side swing driving assembly, and the index finger also has an independent swing function. The extension direction of the first side swing driving assembly is parallel to the extension direction of the finger when the first side swing driving assembly is arranged to stretch, the extension direction of the second side swing driving assembly is crossed with the extension direction of the index finger when the second side swing driving assembly is arranged to stretch, and one end of the second side swing driving assembly extends towards the middle finger, so that the mounting position of the thumb is closer to the middle finger and the index finger. The compact structure of the dexterous hand enables the multiple fingers of the dexterous hand to have independent side swing functions while also considering small size, so that the dexterous hand is suitable for more extensive application scenarios.

The octopus suction cup dexterous manipulator comprises a palm base body and five fingers connected with the palm base body, the five fingers sequentially comprise a little finger, a ring finger, a middle finger, an index finger and a thumb, the little finger, the ring finger, the middle finger, the index finger and the thumb each comprise a first knuckle, a second knuckle, a fingertip and a transmission rope, and the first knuckles, the second knuckles and the fingertips are sequentially hinged; the tail end of the first knuckle is further hinged to the palm base body, one end of the transmission rope is connected with the tail end of the fingertip, and the other end of the transmission rope penetrates through the second knuckle and the first knuckle and then is connected with the driving end of a linear stroke mechanism arranged in the palm base body. Reset mechanisms are arranged at the hinged positions of the first knuckles and the palm base body, the hinged positions of the second knuckles and the first knuckles and the hinged positions of the fingertips and the second knuckles, and suction cups are arranged on the faces, facing the palm center, of the second knuckles. The octopus suction cup flexible manipulator is simple in structure, easy to control and stable in grabbing.

The application belongs to the technical field of space target capturing manipulators, and particularly relates to a bionic eight-claw dexterous capturing manipulator. The technical scheme of the application is as follows: a bionic eight-claw dexterous capturing manipulator comprises a base, a palm, four large fingers, four small fingers, a centering assembly, a push rod assembly and a rope, the palm is fixedly arranged on the base, the large fingers and the small fingers are connected with the palm through the centering assembly and are arranged on the palm at equal intervals; the push rod assembly is arranged between the centering assembly and the center rod of the palm; the palm controls the large fingers and the small fingers to implement actions through the rope. The bionic eight-claw dexterous capturing manipulator provided by the application is simple to operate, has multiple capturing postures, has good adaptability to non-cooperative targets, can reliably capture large-size targets and small-size targets, and has a large capturing range.

The utility model discloses a robot finger opening and closing mechanism, which can drive a swinging finger to swing in a manner that a track plate is driven to move along a guide structure through linear driving power and a guide piece is driven to rotate by taking a swinging fulcrum piece as a center, so that the robot finger can be opened and closed. The device comprises a linear driving power, a track plate and a guide structure, the track plate is slidably mounted on the guide structure, and a swing track groove is formed in the track plate; the little finger mechanism comprises at least one swinging finger except the thumb, a swinging fulcrum piece and a guiding piece are arranged on the swinging finger, the swinging fulcrum piece is installed between the swinging finger and the shell and can rotate, and the guiding piece is installed in the swinging track groove in a sliding mode; the linear driving power is used for driving the track plate to slide on the guide structure, the track plate drives the guide part to rotate with the swing fulcrum part as the center in the sliding process, and the guide part drives the swing fingers to swing in the rotating process. And the guide structure is mounted on the palm mounting seat.
