Description

Multipurpose mini car

Technical field:

Rickshaw, self-propelled vehicle, furniture, ship, body-building apparatus, tourism supplies, buoyant apparatus, office accommodations.

Background technology:

Human work, study, life requirement are extremely rich and varied, and the possible period of want or need of routine and unintended emergency is varied, and the exquisite instrument that all needs people to design and manufacture scientific and efficient is satisfied.But human existing various instrument is the narrow numerous and diverse poor efficiency of function often, has various functional defects and not enough the use, presses for people and carries out integration of science innovation raising as early as possible as quickly as possible.Everybody all needs indispensable dilly and furniture, body-building, tourism, office appliance, has become this type of drawback typical case.For example, too huge heavy the costing an arm and a leg of existing conventional car and can not popularizing, it is excessive to conduct oneself with dignity, and resource is occupied and is consumed too much, and degree of utilization is low, and it is considerable singly to be that the high idle work of no-load ratio is just wasted, and also can pollute harm and blocking up frequently and cause disaster.Though roomy luxurious interior of body is sat comfortable the travelling at a high speed of crouching, man of application required working and studying and fitness training function but still shortcoming studies hard.Carrying capacity is obviously not enough, and the path kissing gate is impassable, can not pivot turn, can not striding ditch, to get over bank unlikely nowhere, individual's carrying completely without may, more can not be lightly many emergent with becoming ship.It also very is slow inconvenience that the occupant comes in and goes out, and can only be confined to the limited carrying in the minority rich and luxurious location at present.Though the light relatively cheapness of other dilly, comparatively universal, no-load ratio is low, wastes lessly, and carrying capacity is strong slightly, and it is not enough that its overall function is still felt deeply, and the safety traveling comfort obviously is short of.It is difficult and dangerous that wherein the cart of consumption maximum is driven control especially, and it is poor protect, can not reliably stay and stop, and overturning easily is afraid of to hit, be afraid of to slide, slide hit to fall and consequence serious.The manpower transport is very difficult.Particularly the higher more simple and crude again easy reciprocal of center of gravity is slided and is used various lots of ordinary bicycle, the any additional functionality service of sit crouching or the like of writing almost completely can not be provided, maximum is had an effect and limited to by body weight, starting is slow, the speed of a motor vehicle is low, the safety extreme difference very easily falls damage and hinders in the various wipings of slipperiness on roads are bumped.During the small-sized obstacle of circuitous ditch step, though strong person can be crossed in the mode of carrying on one's shoulders or with both hands, yet very painstaking.The middle real formula structure of existing vehicle.Far away apart from scolding outside body gravity, make human body can't reach the reasonable honest naturally posture of having an effect efficiently with the car body harmony human body at all.Though so car body weight reaches human capabilitiy's limit far away, carry the unreasonable mode of tiltedly shouldering of having an effect because of being forced to adopt askew body to turn round the side, and make strong person all be difficult to be competent at, the ordinary people weakling can only hang back.Present battery-driven car has begun to popularize, though laborsaving rapid, deadweight increases makes its carrying difficult more inconvenient.One meets the blast heavy rain, and riding all is the devil, and is difficult to the low rain cape of the standing usefulness again deficiency of keeping off the rain, and but often blocks sight line and makes dangerously, even hides the flap nose and hinders and breathe, and brews many traffic accidents with in privation.Ordinary bicycle is taken thing inconvenience, needs special colligation, normally parks promptly and can bump promptly slightly, car more can mutually collude card when crowding more and move inconvenience, even can be as domino, a touching is the sheet pressure superposition that inclines again slightly, miserable attitude foot makes strong person also feel painful unhappy hardships embarrassing.More do not hope them that the service of various furniture, canoe, body-building apparatus, tourism supplies, working and studying, first aid stretcher or the like function can be provided whenever and wherever possible.Even and if can provide the very worthy existing utensil of this service available in all varieties, also big portion can only confine within the remote small space of minority, can not in time serve with the people with car, but often the aid is too slow to be helpful in the real urgent need of people, causes dual waste.In a word, the can not be efficient and rational fully various of existing dilly and various relevant appliance in time satisfied the varied and colorful current demand of people hand and foot, has been undisputable fact.
