A finger exoskeleton device adapting to external force and a motion decoupling method thereof
The application provides a finger exoskeleton device and a motion decoupling method thereof, a middle phalanx transmission mechanism arranged at a proximal phalanx part and connected with a driving mechanism; a distal phalanx transmission mechanism arranged at a distal phalanx part and connected with the middle phalanx transmission mechanism; and the driving mechanism is used to provide power. The application has the beneficial effect that the finger exoskeleton device and the motion decoupling method thereof can increase the rotation angle of the distal phalanx by decoupling the motion of the distal phalanx and the middle phalanx under the stress action of the middle phalanx only when the grip is insufficient, so that the grip is sufficient.

Contact system and changeover switch
ActiveCN224318319Ularge rotation anglesave spaceContact surface shape/structureContact electric connectionTransfer switchElectrical connection
A contact system includes a contact support and a moving contact. The moving contact has moving contacts at both ends that mate with stationary contacts. The contact support has two raised mounting protrusions on the side away from the stationary contacts, and a clearance notch between the two mounting protrusions. Each of the two mounting protrusions of the contact support has at least one contact spring, and the contact springs on the two mounting protrusions are respectively connected to the two ends of the moving contact where the moving contacts are located. A changeover switch includes a housing and a contact system. The housing contains a load terminal, a power supply I terminal, and a power supply II terminal. The load terminal is electrically connected to the moving contact. Two stationary contacts are respectively located on the power supply I terminal and the power supply II terminal. In this invention, the contact support has a notch design on the side near the load terminal, and two mounting protrusions are spaced apart for mounting contact springs, saving space and increasing the rotation angle of the contact support.
