Abstract
The utility model relates to a place or path covered with a metal plate for supplying safety extra-low voltage to an electronic vehicle, and a sheet metal is used as an electric pole to cover the surface of the place or path at the driving range of the electric vehicle. A coating layer is composed of more than two electric poles, and can make the electric vehicle obtain the electric energy at an optional position of the place or path. The electric vehicle can be operated according to the will of a driver, and can drive towards any direction. The utility model overcomes the disadvantages of low energy utilization, troublesome repair, high expense, etc., and achieves the electrical energy conversion efficiency of the exiting trolleybuses and the railroad cars.
Description
The utility model mainly is applicable to visit, recreation electric motor car.
At present, the existing both at home and abroad vehicle (abbreviation electric motor car) that drives by electric energy is broadly divided into five kinds by its structure and power supply unit: the electric motor car of A. rail, comprise tram, electric locomotive, and provide electric energy by trolley wire and rail; B. trolleybus is obtained electric energy by current-collector on the car from trolley wire; C. battery truck provides electric energy by vehicular power-bottle (battery); D. telpher directly provides electric energy to winch by cable; E. the solar cell car leans on the photoelectric effect of solar cell to produce current drives.
In the above-mentioned electric motor car, A, B, D, three kinds of cars.The utilization rate of electrical height, power draw is big, but must travel along rail, trolley wire or wirerope, and the occasion that is unsuitable for travelling flexibly has limitation.E kind car, promptly the solar cell car because solar cell price height involves great expense it, does not enter the practical stage as yet.C kind car is battery truck, is widely used in inside plants and recreation ground at present, and mobility is higher, but utilization rate of electrical is low in operation and charging process, and the tired lock of the maintenance of storage battery makes that the operating cost of this car is higher.Its performance can not improve a lot before battery (being storage battery) has bigger improvement.
The electronic Amusement vehicle of domestic production, second-rate, this car adopts lead-acid accumulator more, and volume is big, and is heavy, energy consumption is high.In use, also have the charging interval long, the shortcoming that discharge time is short.Must change one-shot battery in several hours that have, very inconvenient.The also tired lock of the maintenance of battery will add acid, adding distil water according to the different situations of electrolyte in the battery, is difficult to guarantee that it works in optimum state, causes many storage battery life-span less thaies 1 year, and scraps in advance.
It is a kind of to electric motor car power supply that the purpose of this utility model is to provide, and the electric motor car place or the road that can freely travel thereon.
The utility model adopts metal sheet to cover place or road surface as electrode, auxilliary establishing on firmer basis, the number of poles of each place or road is greater than 2, and each place or the area size on ground, road path electrode sum visual field or the width of road are determined.The electrical distribution system of this place or road adopts security transformer that civil power is become safe ELV and uses.
Performance of the present utility model and characteristics are:
One, two of regular arrangement can make electric motor car travel to all directions neatly on place or road with top electrode, have overcome the limitation that tram and trolleybus must travel along rail, trolley wire; Electric motor car adopts trolley head to obtain electric energy without storage battery, make the electric motor car weight reduction, can adopt lower-powered motor, thereby cost reduces, and energy utilization rate improves, and has overcome battery truck maintenance cost height, the shortcoming that energy utilization rate is low.Electric vehicle is many obtains electric energy to trolley head from this place or road, all has two or more trolley heads to touch any two adjacent electrodes respectively so at an arbitrary position.If owing to have two trolley heads to touch any two adjacent electrodes respectively, can finish current supply circuit, so the current continuity of electric motor car is fine.Because of electric motor car power less (about 120W), though power with 9V safety ELV, operating current is little (about 13A) also again, and the speed of a motor vehicle is lower in addition, and trolley head is contact electrode reliably, so the application life of trolley head is longer.
Though two when building this Amusement vehicle place or road, with common storage battery parking lot compare, expense need exceed 1.3 times.But the expense of electric motor car is lower, and especially in running, energy cost, maintenance cost all can reduce significantly, and total expense will reduce.
Three, safe and reliable, meet the regulation of the IEC of International Electrotechnical Commission standard " family expenses and similar security appliance ", and consider under worst environment and use, leave sufficient leeway.
According to IEC publication 335-1; relevant fund (2.2.19,2.2.21,2.2.22,8.4) in the 1970 general requirements; the utility model is categorized as III level electrical equipment (seeing 2.19) by electrical shock protection; be the whole ELVs safe in utilization of electrical system (seeing 2.2.21) of place or road path electrode and electric motor car; and the low 33V of higher limit than safe ELV leaves sufficient surplus.
The electrical distribution system of this place or road adopts security transformer (seeing 2.2.22) and mains isolation, and security transformer is a double insulation, and the coiling of primary and secondary winding independence is fool proof reliable.
This utility model is used for outdoor more, and form by exposing the formula electrode, under situations such as rainfall snowfall, may touch conducting liquid, according to " except that the live part of working, palp conducting liquid must directly not contact with live part under being no more than the safe ELV of 24V." regulation of (seeing 8.4), this utility model is having under the conducting liquid situation, also is safe and reliable.
In the use, human body might directly touch this place or road surface, for confirming its security performance, and again according to IEC publication 335-22, pertinent regulations in the specific (special) requirements of 1975 electric toys (civil power operation):
" 1.1 standards are applicable to the civil power operation, are used in the electric toy around indoor and the house, and for 5～13 years old entertainment for children and education, it comprises following power toy.
A, by chargeable battery-driven:
B, drive: 1) direct by civil power; 2) by a transformer.……
This standard is considered when ' indoor and outdoor ' used, the wrong mode of occupation that may run into, but do not stipulate to prevent to surpass the test procedure level and the requirement of abusing.”
" 8. electrocution-proof protection ... 8.1 replace: ...
Except that III level condition with electric light under current potential, must protect with non-removable cover.……
The parts that are in voltage under the III level condition are not considered to live part.”
According to afore mentioned rules, the utility model in normal use not only personnel onboard or wear footwear and stand on the electrode fool proofly and under improper mode of occupation, touch electrode as barefoot, hand and also can guarantee safety.
