Abstract
A photoelectric type gear selector is composed of an input and output cable and a control box which are connected. Input and output signals of the control box are connected with a vehicle electrical and operation valve through a coupler on the cable. A fork-shaped shaft connected with a control lever is arranged in the control box, the fork-shaped shaft is connected with a groove-shaped cylinder, and the control lever stirs in the front and rear direction so as to drive the groove-shaped cylinder to rotate. A circuit board is installed above the groove-shaped cylinder, and a photoelectric switch which is used for detecting the position change of the groove-shaped cylinder and determining gear of a gear box is installed on the circuit board. The photoelectric type gear selector adopts the photoelectric switch as a sensor, determines different gear selection by detecting the position change of the groove-shaped cylinder, determines the rotation direction of the gear box through the position change of two guide sleeves, converts position information into electric signals through the sensor, and the electric signals drive an operation valve of the gear box after being transmitted through a signal relay logic converting amplification circuit so that the purpose of gear change of the gear box can be achieved.
