Motor starter for remote control model vehicle

Abstract

The invention discloses a motor starter for a remote control model vehicle. A clutch unit is arranged between a reduction gear set of a driving unit and a gear transmission unit, after power output to the reduction gear set by a motor of the driving unit is stored to be up to a default by the clutch unit, the power is transmitted to an engine of the remote control model vehicle through the gear transmission unit and a torque output shaft, and the engine of the remote control model vehicle can obtain enough torque at a time and can be rapidly started. In addition, the clutch unit can idle when reverse feedback force is generated by flameout of the engine, a transmission relationship among the clutch unit, the reduction gear set and the gear transmission unit is relieved, and the damage of the gear structure can be effectively avoided.

Description

technical field [0001] The invention relates to a remote-controlled model car, in particular to an electric starter for a remote-controlled model car. Background technique [0002] Remote control model cars can have different starting methods depending on the type of car. In order to reduce the weight of the car body, the racing car usually uses a starting platform to start the engine, while the non-racing car has no concerns about reducing weight. There will be a pull starter or an electric starter inside the body to start the engine. As far as the known electric starter is concerned, it mainly uses the reduction gear set and the gear transmission unit to reduce the power output by the motor and then transmit it to the torque output shaft. The torque output shaft will generate torque to drive the crankshaft of the engine to rotate. Used to start the engine. [0003] However, at the moment when the motor is just started, the deceleration effect provided by the reduction ge...

Problems solved by technology

[0003] However, at the moment when the motor is just started, the deceleration effect provided by the reduction gear set and the gear transmission unit will make the torque generated by the torque output shaft not enough to drive the crankshaft of the engine for the required number of turns, so that the engine cannot run smoothly at one time. After completing the start, the motor must be started several times in a row to increase the torque generated by the torque output shaft to complete the start of the engine; in addition, if the running remote control model car suddenly overturns and the engine stalls, the crank of the engine will The shaft may reverse due to gravity. At this time, the crankshaft will reversely transmit a feedback force to the gear transmission unit. Since the gear transmission unit and the reduction gear set are kept in a state of mutual connection, plus the reduction gear set It will be affected by the resistance of the power output shaft of the motor and cannot rotate freely. Therefore, the gear transmission unit must bear most of the feedback force, causing the gears of the gear transmission unit to be easily damaged
