<p>This invention discloses a steering structure of a toy plane and an infrared four-channel remote-control electric toy plane. The steering structure of the toy plane includes small internal guide (91), large external guide (92), elliptical shaft (93), and sector gear (94); the small internal guide has a rectangle hole (911) with rounded angles and two arc-back bosses (913), and driven by the sector gear, the small internal guide contacts the elliptical shaft along the second and fourth quadrants; the large external guide has the elliptical hole, and driven by the sector gear, the large external guide contacts the elliptical shaft along first and third quadrants. The small infrared four-channel remote-control plane has adopted such a steering structure, which allows the small internal guide or the large external guide to change the rotating direction of the lower propeller by contacting the elliptical shaft, so as to realize a simple steering structure, also large reduction on product cost, and the functions of Forward/Backward and Left Turn/Right Turn of mini toy plane is achieved.</p> |
