Multidirectional input device, control handle, and manipulation device

Abstract

This application provides a multi-directional input device, a control handle, and a control device. The multi-directional input device includes a housing, a rocker arm, a linkage element, a circuit board, and an electrical connection element. The linkage element is at least partially located within the housing and rotatably disposed thereon. The rocker arm is drivenly connected to the linkage element. The linkage element includes a first linkage member and a second linkage member. At least one of the first and second linkage members includes a linkage member body, screw-in portions disposed at both ends of the linkage member body, and an operating portion extending toward the housing from either screw-in portion. The electrical connection element is disposed on and electrically connected to the circuit board, and the operating portion is drivenly connected to the electrical connection element. By integrating the electrical connection element into a cavity within the housing, the size of the multi-directional input device can be reduced.
