Summary of the invention
In order to overcome existing toy helicopter above shortcomings part, the utility model purpose is to provide that a kind of to have a drives structure device simple, body is light, produce and install very convenient, the flying speed and the still good toy helicopter of performance of having a smooth flight.
The utility model purpose is achieved through the following technical solutions: a kind of toy helicopter structure, comprise body, undercarriage, the rotation wing, empennage, undercarriage is positioned at the bottom of body, the rotation wing is positioned on the body, empennage is positioned at body rear end, be provided with drive unit in the described body, described drive unit comprises: motor, driving gear, on rotate wing gear, backspin rotor gear, described motor is connecting driving gear, and driving gear connects goes up rotation wing gear and backspin rotor gear; The middle part, abdominal cavity of described body is provided with installing plate, and motor is fixed in the installing plate below, connects rotating mechanism on the described drive unit.Described rotating mechanism comprise rotation wing gear, flywheel, on rotate wing power transmission shaft, backspin rotor gear, backspin rotor power transmission shaft, bearing, bearing block; The described rotation wing geared sleeve of going up is connected on the rotation wing power transmission shaft, last rotation wing power transmission shaft one end is socketed with flywheel, last rotation wing power transmission shaft is through going up in the rotation wing power transmission shaft that backspin rotor gear connects, the last rotation wing power transmission shaft other end is connecting rotation wing fixed mount, is socketed with bearing one end on the backspin rotor power transmission shaft and is connecting backspin rotor fixed mount; Described bearing is connected in the bearing block of body upper.
The below of the installing plate described in the such scheme is symmetrically connected with two motors.
Bearing top circle described in the such scheme is provided with projection, and projection embeds in the groove of bearing block; Described bearing block two ends are connecting two bearings.
The front end bottom of the body described in the such scheme is provided with power pack, and the below at middle part, body abdominal cavity is provided with the IC plate.
Bearing block described in the such scheme and body are overall structures.
The good effect that the utility model produced is: because the technical program is that motor is adopted underneath type, shortened the length of power transmission shaft, thereby big spoke degree has improved the stability of rotation wing running, by reasonable in design to putting of motor and power supply, the overall aircraft weight saving that makes makes and to take off very steadily that balance quality is fine, speed during flight is corresponding to increase, and interest and persistence when children play also are improved.
