Background technology
Along with the development of urbanization, traffic congestion is day by day serious, electric unicycle appear as the walking-replacing tool that people bring a kind of volume little, flexible.Then traditional electric unicycle requires higher to road conditions, if it is smooth or have handstone to run into Uneven road, can allow driver like a hen on a hot girdle.
The widespread use of electric unicycle, not still because environmental protection and energy saving, also because the very light in weight of electric unicycle, has good portability.China Patent Publication No.: CN203511895U discloses a kind of hydraulic shock-absorption electric unicycle, solves the damping problem of electric unicycle, but due to general liquid damper all heavier, this makes electric unicycle carry inconvenience, and application is restricted.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, a kind of damping electric unicycle is provided, this electric unicycle is provided with air cushioning air bag in the lower end of pedal, when wheelbarrow travels on uneven road surface, air cushioning air bag plays cushioning effect, reduces the sense of discomfort that drivers produces because of wheelbarrow vibrations, simple and practical, good damping effect, and lightweight, be convenient for carrying.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of damping electric unicycle, it is characterized in that, comprise car body and be arranged on the cuboidal pedal on car body, inflation pump is provided with in described car body, the lower end of described pedal is provided with air cushioning air bag, the upper end of described air cushioning air bag is provided with upper cover plate, the lower end of described air cushioning air bag is provided with lower cover, upper cover plate is fixed on the upper end of air cushioning air bag by described upper cover plate by bolt, lower cover is fixed on the lower end of air cushioning air bag by described lower cover by bolt, girdle ring is set with in the middle part of described air cushioning air bag, packing seal is provided with between the upper end of described upper cover plate and the lower end of pedal, the outlet side of described inflation pump is connected with air cushioning air bag.
Above-mentioned a kind of damping electric unicycle, is characterized in that, described air cushioning air bag is made up of rubber.
Above-mentioned a kind of damping electric unicycle, it is characterized in that, described upper cover plate and lower cover are stainless steel.
Above-mentioned a kind of damping electric unicycle, is characterized in that, described bolt is criss-cross countersunk-heat bolt.
The utility model compared with prior art has the following advantages:
1, the utility model is simple and practical, good damping effect, electric unicycle lightweight, is convenient for carrying, can be applicable.
2, the utility model is provided with air cushioning air bag in the lower end of pedal, and when wheelbarrow travels on uneven road surface, air cushioning air bag plays cushioning effect, reduces the sense of discomfort that drivers produces because of wheelbarrow vibrations.
In sum, the utility model is provided with air cushioning air bag in the lower end of pedal, when electric unicycle travels on uneven road surface, air cushioning air bag plays cushioning effect, reduce the sense of discomfort that drivers produces because of wheelbarrow vibrations, simple and practical, good damping effect, and lightweight, be convenient for carrying.
Below in conjunction with drawings and Examples, the utility model is described in further detail.

Detailed description of the invention
As depicted in figs. 1 and 2, the cuboidal pedal 2 that the utility model comprises car body 1 and is arranged on car body 1, inflation pump 8 is provided with in described car body 1, the lower end of described pedal 2 is provided with air cushioning air bag 3, the upper end of described air cushioning air bag 3 is provided with upper cover plate 4, the lower end of described air cushioning air bag 3 is provided with lower cover 7, upper cover plate 4 is fixed on the upper end of air cushioning air bag 3 by described upper cover plate 4 by bolt 5, lower cover 7 is fixed on the lower end of air cushioning air bag 3 by described lower cover 7 by bolt 5, girdle ring 6 is set with in the middle part of described air cushioning air bag 3, packing seal 9 is provided with between the upper end of described upper cover plate 4 and the lower end of pedal 2, the outlet side of described inflation pump 8 is connected with air cushioning air bag 3.
In the present embodiment, described air cushioning air bag 3 is made up of rubber.
In the present embodiment, described upper cover plate 4 and lower cover 7 are stainless steel.
In the present embodiment, described bolt 5 is criss-cross countersunk-heat bolt.
Principle of work of the present utility model is: when air cushioning air bag 3 works, and air cushioning air bag 3 inner chamber is filled with pressurized air, forms a pressurized air gas column.Along with the increase of the vibrational load amount of electric unicycle, the height reduction of air cushioning air bag 3, cavity volume reduces, and the rigidity of air cushioning air bag 3 increases, and the effective bearing area of inner chamber air column strengthens, and now the load-carrying capacity of air cushioning air bag 3 increases.When the vibrational load amount of electric unicycle reduces, the height of air cushioning air bag 3 raises, and cavity volume increases, and the rigidity of air cushioning air bag 3 reduces, and the effective bearing area of inner chamber air column reduces, and now the load-carrying capacity of air cushioning air bag 3 reduces.Like this, air cushioning air bag 3 in actv. stroke, the height of air cushioning air bag 3, cavity volume, load-carrying capacity along with electric unicycle vibrational load increase progressively with reduce to there occurs that pulsation-free flexibility is transmitted, the efficient control of amplitude and shock loads.Can also by the method increasing, subtract charge air, the rigidity of adjustment air cushioning air bag 3 and the size of bearing capacity; Can also auxiliary tank be set up, realize automatic control and regulate.
In AW=F/P formula:
AW-air cushioning air bag 3 payload space, mm
2;
F-air cushioning air bag 3 load, kN;
The interior pressure of P-air cushioning air bag 3, MPa;
Utilize this characteristic, bicyclist tramples the upper end at pedal 2, and now bicyclist is carried on this air cushioning air bag 3, and the gas volume that its bicyclist's weight is compressed downwards will transfer support elastic force upwards to.At ordinary times, this air cushioning air bag 3 is set to softer elasticity modulus; And when taking advantage of year more weight, the gas be compressed also can provide larger upwards bearing force, and is not easy to feel that its elastic force has any decline.And air cushioning air bag 3 is compared with traditional bumper, compared with many tiny resiliences concussion can be absorbed, so passenger can be made to experience comparatively comfortable taking sense.
The above is only preferred embodiment of the present utility model, not imposes any restrictions the utility model.Every above embodiment is done according to utility model technical spirit any simple modification, change and equivalence change, all still belong in the protection domain of technical solutions of the utility model.
