Description

Outboard engine throttle gear automatic adjustment device

technical field

The invention relates to an outboard engine device.

Background technique

The surface unmanned boat using the outboard motor as the propulsion device has a wide range of application prospects, and one of its key technologies is to realize the automatic control of the throttle and gear position of the outboard motor. The throttle and gear position of the outboard motor generally adopt a purely mechanical control method, and the throttle and gear position are adjusted respectively by pulling the throttle line and the gear position line. The existing automatic throttle gear control device mainly adopts the structural form of a ball screw or a rack and pinion.

There are already related products for the ball screw type shift actuator. The rotation of the screw is converted into the linear motion of the nut through the ball screw, thereby pulling the gear line to realize the gear shifting operation. The advantages of this structure are high precision, large thrust, and smooth movement, but the disadvantages are slow speed and short transmission distance.

Patent No. US5352138 discloses a remote control device for the throttle position of an outboard motor, which adopts a rack and pinion structure. The remote controller of this device is connected with the rack and pinion structure. The operator pulls the rack to drive the gear to rotate. After the system detects the rotation amount of the gear, it controls the motor to rotate, and then pulls the throttle line or gear line through a rack and pinion structure. The advantages of this structure are large bearing capacity, long transmission distance, and simple structure. The disadvantage is that it requires high processing and installation accuracy. If the processing and installation accuracy is poor, the transmission noise will be large and the wear will be large.

To sum up, at present, it is necessary to seek an automatic adjustment device for the throttle position of an outboard engine with fast action and high position accuracy.
