Control stick apparatus

Abstract

The invention discloses a control stick apparatus which mainly comprises a fixed seat, a straight shaft assembly and an arc shaft assembly. The fixed seat is a box shaped body with an upper opening and a lower opening. The straight shaft assembly and the arc shaft assembly are in vertical crossed symmetrical arrangement and are installed on the fixed seat through a shaft sleeve with an outside thread. A center of the straight shaft assembly is superposed with that of the arc shaft assembly. A rocking bar is installed at the superposition center. Two ends of the straight shaft assembly and the arc shaft assembly are provided with a shift balance wheel and a potentiometer balance wheel respectively. On the fixed seat, a position corresponding to the shift balance wheel is provided with a swing rod assembly, and a position corresponding to the potentiometer balance wheel is provided with a gear which is engaged with the potentiometer balance wheel. The gear drive an antenna of a potentiometer installed with the gear to move, and a signal of each level of shift is sent out through the enclosed potentiometer. The shift balance wheel is engaged with a bearing on the swing rod assembly, and a clear shift sense is brought to an operator. The control stick apparatus has the advantages of the clear shift sense, a good sealing effect and convenience in use.

Description

technical field [0001] The present invention relates to motor tools with operating controls, and more particularly to a joystick device. Background technique [0002] At present, the general joystick device mainly includes a fixed mount and a rocking bar and a swing shaft part installed on the fixed mount. The rocker rotates in the middle of the ball recess formed by the pressure plate and the fixed frame with the ball in the middle as the fulcrum, and the side walls of the front end of the rocker respectively touch the inner walls of the middle grooves of the two pendulum shafts arranged crosswise, driving the two pendulum shafts along the The shaft installed on the fixed seat rotates, and when the two pendulum shafts are swinging, the pendulum teeth at one end engage with the teeth on the fixed frame, and the angle between the teeth forms a controlled gear position. The transmission of the position signal is through the reciprocating movement of the contact pins at the ot...

AI Technical Summary

Problems solved by technology

[0003] There are three defects in the joystick of this structure: because the swing teeth at one end of the swing shaft and the teeth meshing with the swing teeth on the fixed frame are all castings, the precision is not high, so the gear sense for the operator is not clear; because The four sides of the fixed frame are open, and the circuit for transmitting electrical signals is also open, so the sealing effect is not good; the fulcrum of the rocker needs to be lubricated, and it is easy to stick to dust
