A joystick device 10 disclosed herein provides a return function for urging a lever 20 to its initial position. The device includes a first spring 30 and a second spring 40, each of which extends along the lever 20 and is disposed between an upper spring seat 32 and a lower spring seat 34. The springs 30 and 40 are subjected to compression to provide an urging force as the lever 20 is tilted from the initial position.

The present invention relates to the field of remote-control technology, and provides a remote control for remotely controlling a motorized device, the remote control including a first rocking lever device, a second rocking lever device, a processor and a signal transmitting device. A rod of the first rocking lever device is configured to perform a linear movement along a first direction and a second direction, so as to trigger the remote control to generate a first remote control instruction and a second remote control instruction, and is further configured to rotate along a third rotation direction and a fourth rotation direction, so as to trigger the remote control to generate a third direction and a fourth direction. The first direction is opposite to the second direction, and the third direction is opposite to the fourth direction. The processor is connected to the first rocking lever device and the second rocking lever device to process the first remote control instruction, the second remote control instruction, the third remote control instruction and the fourth remote control instruction.

An operation device includes a lever configured to be tiltable; a substrate; a first resistor disposed on the substrate to extend in a first direction; a first actuator configured to rotate in accordance with tilting of the lever; and a first holder configured to hold a first slider and cause the first slider to slide on the first resistor by moving in the first direction via a first drive transmission part in accordance with rotation of the first actuator. The first drive transmission part includes a first protrusion integrated with the first holder and protruding in a second direction, and a first engagement portion integrated with the first actuator and including a pair of holding pieces configured to hold the first protrusion from both sides in the first direction. A first holding piece of the holding pieces is more elastic than a second holding piece of the holding pieces.

A synchronous joystick sensor is provided, the synchronous joystick sensor includes a joystick, a joystick arm assembly, a swing detection assembly, a reset assembly. The joystick arm assembly is sleeved on the joystick, the arm assembly is driven by the joystick to swing in a first direction and a second direction perpendicular to the first direction. The swing detection assembly is configured to swing detection assembly, and configured to measure the swing amount in the first direction and the second direction through a magnetic detecting element, and convert the swing amount into a first electronic signal and a second electronic signal; a reset assembly configured to make the joystick being in a vertical reset state when there is no external force.

This disclosure describes systems, devices, apparatuses, and methods of adjusting a resistance of user-input device, such as a joystick. In particular configurations, the device includes a joystick configured to rotate about a first axis and a second axis and a first resistance mechanism coupled to the joystick. The first resistance mechanism can include a rotary damper configured to selectively resist rotation of the joystick about the first axis and a processor in communication with the rotary damper and configured to adjust a resistance torque of the rotary damper. The rotary damper may provide resistance through manipulation of a magnetorheological (MR) fluid in the fluid damper.

A joystick device including a hollow housing having an endless boundary structure and a ceiling structure with an opening; a control-stick having a head portion and a stem portion, the hollow housing surrounding the stem portion with the head portion outside the hollow housing; and a plurality of biasing curved arm members extending outwardly from the stem portion and movable with the control-stick as a whole relative to the hollow housing along a plane at least substantially perpendicular to the stem portion. Each of the plurality of biasing curved arm members having a curved segment with a convex side directed towards a respective corresponding portion of the endless boundary structure so as to bias the stem portion when the control-stick is being moved towards said portion. The plurality of biasing curved arm members being distributed around the stem portion so as to cooperate with each other to centre the control-stick.

An operation device includes a lever configured to be tiltable; a substrate; a first resistor disposed on the substrate to extend in a first direction; a first actuator configured to rotate in accordance with tilting of the lever; and a first holder configured to hold a first slider and cause the first slider to slide on the first resistor by moving in the first direction via a first drive transmission part in accordance with rotation of the first actuator.
