Abstract
The utility model relates to a toy car driven by the elastic force, which is a teaching aid of teachers and a learning aid of students regarding to machine primary construct teaching content in primary school natural teaching material. The utility model is provided with a car chassis, a front and a rear wheels, a front and a rear axletrees, a front and a rear axle bearing seats, a hood. The utility model is characterized in that a big gear and a small gear are arranged in a gear slot of the car chassis; the big gear is arranged on an elastic axis; both ends of the elastic axis is fixed at both sides of the gear slot; the small gear is arranged on the rear axletree; the big gear and the small gear are engaged with each other; the elastic axis is composed of rubber band or other elastic body.
Description
The utility model elastic dynamic car relates to is about teaching aid and student's learning aid of the essential structure content of courses of machine in a kind of primary school nature teaching material.
In the primary school nature teaching material relevant for the content of courses of the essential structure of machine, existing toy car kind is more, complex structure, technical merit is also higher, but three elements to gear, gear drive and the machine of showing machine are then unclear, and toy does not replace teaching aid and learning aid.
The purpose of this utility model is that the weak point at above-mentioned existence provides a kind of elastic dynamic car, the employing elastomer is a power, travelling gear promotes car and advances, simple in structure, easy and simple to handle, three elements of gear and gear drive and machine, know to show intuitively, be convenient to teacher education, student's study, to improve educational effect.
The elastic dynamic car takes following scheme to realize: elastic dynamic car primary structure is made of car chassis, car wheel, axletree, gear wheel, pinion, hood.Front axle bearing block, back axle bearing block are arranged at bottom, car chassis, forward and backward axletree is housed respectively, car front truck arbor wheel driven pulley is equipped with at the front axle two ends), rear wheel (driving wheel) is equipped with at the back axle two ends, be provided with gear wheel, pinion in the chassis gear grooved, the gear wheel device is on elastic shaft, and the elastic shaft two ends are fixed on the gear grooved both sides, pinion device on back axle, two gears engaged.Chassis top is hood, is provided with vehicle window.Elastic shaft can adopt rubber band or other elastomers.
Demonstration operation and operation principle: gear wheel is rotated toward certain orientation with hand, making the gear wheel elastic shaft is that rubber band or other elastomers are twisted into rope form, savings elastic force, again that gear wheel and pinion is good, car is lain on the level and smooth desktop then, decontrol hand, the rubber band that elastic shaft is promptly reversed on the gear wheel, restore to the original state, just discharge elastic force, the gear wheel rotation driving pinion rotates, and pinion rotation speed (angular speed) is more fast again than gear wheel, thereby makes the car segment distance that advances on level and smooth desktop.
The elastic dynamic car is simple in structure, gear drive is fully aware of, and three elements of machine are clear, directly perceived, adopts that elastic shaft is fairly simple as power, cost is low, simple to operate.The elastic dynamic car can be used as teaching aid and student's learning aid of the essential structure of associated machine in the primary school nature teaching material, is convenient to student's study, grasps, and improves teaching efficiency greatly.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is an elastic dynamic car front view.
Fig. 2 is an elastic dynamic car upward view.
Constitute by car chassis 3, wheel, axletree, gear wheel 11, pinion 8, hood 2 with reference to accompanying drawing elastic dynamic car primary structure.3 bottoms, car chassis have front axle bearing block 13, back axle bearing block 9, front axle bearing block 13 that front axle 4 is housed, car front vehicle wheel 5 is equipped with at the front axle two ends, makes driven pulley, and back axle bearing block 9 is equipped with back axle 7, rear wheel 6 is equipped with at the back axle two ends, makes driving wheel.In chassis gear grooved 12, be provided with gear wheel 11, pinion 8, gear wheel 11 devices are on elastic shaft 10, elastic shaft is made of rubber band or other elastomers, and the elastic shaft two ends are fixed on gear grooved 12 both sides, pinion 8 devices two gears engaged on back axle 7.On 3 tops, chassis is to be provided with vehicle window 1 on hood 2, the hood.Hood can adopt transparent plastic or paper material to constitute, and chassis, wheel, large and small gear all can adopt plastics to make.
Claims (2)
