Description
Technical field
The present invention relates to a kind of teaching aid car, particularly a kind of teaching aid car with toy functions that uses hydrogen to act as a fuel.
Background technology
Along with the development in epoch, the more and more abundanter and scientific and technical integrated level of the kind of toy for children is also more and more higher.In addition, hydrogen (H
2) more and more accepted by people as a kind of new forms of energy of environmental protection.Therefore, the development of Hydrogen Energy teaching aid car and exploitation more and more are subject to people's attention.Enjoyment and cultivation esthetic sentiment when these Hydrogen Energy teaching aid cars have on the one hand sight and operability and can increase children and play, these Hydrogen Energy teaching aid cars can also be as educational aid on the other hand, for the teenager explains the knowledge that hydrogen energy source changes into electric energy, play the purpose of scientific popularization and education.
Granted publication number discloses a kind of hydrogen-driven toy truck for the Chinese patent of CN1981905B, as shown in Figure 1, existing hydrogen-driven toy truck comprises a chassis 31, four wheels 32, fuel cell 33, hydrogen-storing device 34, motor 35, gear case 36, power switch 37, hydrogen gas valve 38, hydrogen inlet pipeline 39, hydrogen connecting pipe 40, axletree 41 and transmission lines of electricity 42.
The principle of work of existing hydrogen-driven toy truck is: filling hydroformylation stage, make power switch 37 be in off-state, open hydrogen gas valve 38, external hydrogen is input to the hydrogen gas side of fuel cell 33 from hydrogen inlet pipeline 39, and by hydrogen connecting pipe 40 hydrogen is flow in the hydrogen storage vessel in the hydrogen-storing device 34, along with the inflow of hydrogen, hydrogen storage vessel expands, after hydrogen storage vessel is full of hydrogen, close hydrogen gas valve 38.In the electricity consumption stage, power turn-on switch 37, the electric current that fuel cell 33 is produced flows into motor 35, the motion that rotarily drives gear case 36 of motor, and then drive axletree 41 interlocks, toy car has just moved.
Existing hydrogen-driven toy truck exists following shortcoming: first, there is not accumulator system, because existing hydrogen-driven toy truck only has hydrogen energy source system and other accumulator system is not set, after limited hydrogen energy source exhausts, hydrogen-driven toy truck can not walk on, as the teaching demonstration instrument time, hydrogen energy source system can generate electricity and support 5-7 minute in (the 36th section in patent CN1981905B instructions), what therefore do not have accumulator system can not produce serious problems, but, when playing for children as toy for children, do not have accumulator system to be difficult to satisfy in time the requirement that children play, so problem reduction is to be difficult to satisfy the play requirement of time of children; The second, there are not wind energy system and solar energy system, because new forms of energy comprise wind energy, sun power, tide energy, geothermal energy and Hydrogen Energy, after having explained the new forms of energy kind, only can demonstrate by hydrogen-driven toy truck the principle of hydrogen power generation and use, can generate electricity and use for the new forms of energy of other kind does not have test basis, therefore be difficult to so that the teenager understands and convinces, so problem reduction is that the new forms of energy kind is too single that causing can only be as the educational aid of simple function; Three, the toy car mechanical function is too simple, because existing hydrogen-driven toy truck does not arrange speed change system and automatic turning function, therefore existing hydrogen-driven toy truck can only be with a kind of speed motion, and can not auto-steering when running into barrier and avoiding obstacles, therefore can not use as toy for children flexibly, so problem reduction is without speed change and turning function.
