Description

Simplify the mini electric vehicle development platform

Technical field

The present invention relates to International Classification of Patents B60L elec. vehicle engine installation technology, the especially a kind of simplification mini electric vehicle development platform that can develop as the battery-driven car functional depth basis.

Background technology

Electronlmobil refers to travel with power wheel take vehicle power as power, meets the vehicle of arteries of communication, legislative control on safety requirements.Because less to the relative orthodox car of environmental concerns, its prospect is extensively had an optimistic view of, but generally believes that current vehicle technology is still immature.

The day by day exhaustion of the continuous soaring and natural resources of world energy sources demand has all proposed new challenge to energy supplier, industrial enterprise and customer, uses the energy to become the task of top priority in efficient and continuable mode as far as possible.Battery-driven car receives publicity day by day, but, based on cognition and the use habit of existing customer to automobile, and the huge and ripe prior art production capacity of manufacture, must affect current electric vehicle structure design, not only fail enough design optimization potentiality of developing under the electronlmobil concept, and kept too much the structural very complicated of fuel-engined vehicle.Such as, the rear suspension of existing mini electric vehicle and electrically propelled traction vehicle generally is the vertical steel spring structure of putting, and is similar with same other goods carrying vehicle of level.For front suspension, adopt transverse leaf spring as propons at old-fashioned golf cart, though structure is simple, because the distortion of leaf spring can affect the front wheel alignment angle, wear on tyres is fast.Adopt now increasing gradually of McPherson suspension.Lower swing arm is A type frame form, and front-wheel can obtain larger angle of inclination, is conducive to reduce the car load minimum turning radius.On some miniature low-speed electronic cars, for simplified structure, reduce manufacturing cost, often adopt welded type propons and steering swivel, and with coil spring and Shock absorber propons and vehicle frame are coupled together.

The battery-driven car principle of work is generally: storage battery-electric current-electric governor-electrical motor-power drive system-driving running car.The composition of electronlmobil comprises: the mechanical systems such as driven by power and control system, propulsive effort transmission, finish the equipment of set task etc.Driven by power and control system are the cores of electronlmobil, also are the maximum differences that is different from internal-combustion engines vehicle.Driven by power and control system are comprised of speed-regulating control device of driving motor, power supply and electrical motor etc.Other devices of electronlmobil are basic identical with internal-combustion engines vehicle.Wherein, pure electric automobile is by electric motor driven automobile.The driving energy source of electrical motor is in vehicle-mounted chargeable storage or other energy accumulating devices.Most of vehicle directly adopts motor-driven, and some vehicle is contained in electrical motor in the machinery space, also some directly with the rotor of wheel as four electrical motors, its difficult point is the electric power storing technology.Itself is the pernicious gas of exhaust emission atmosphere not, even be scaled the discharging in power plant by institute's consumption of current, outside sulphur removal and the particulate, other pollutants also significantly reduces, because power plant is built in mostly away from densely populated city, the mankind is injured less, and power plant is fixed, the discharging of concentrating is removed various noxious emissions and is easier to, and has also had correlation technique.Because electric power can obtain from multiple primary energy, such as coal, nuclear energy, waterpower, wind-force, light, heat etc., remove people to the oil resources worry of exhaustion day by day.Electronlmobil can also take full advantage of power charge more than needed during low power consumption in night, and generating set day and night can both be taken full advantage of, and greatly improves its economic benefit.These advantages make the research of electronlmobil and " focus " that application becomes auto-industry just.There is the expert to think, for battery-driven car, the present maximum obstacle process of industrialization that has been exactly infrastructure construction and price, compare with hybrid power, battery-driven car more needs the supporting of Infrastructure, and this not to be an enterprise can solve, need each cartel to get up and build with department of local government, just have the chance of large-scale promotion.

The pure electric automobile advantage is: technology is relatively simple ripe, as long as there is the place of electric power supply to charge; Its shortcoming is: the energy of battery cell's weight storage very little, also the battery because of battery-driven car is more expensive, do not form again cost-saving scale, therefore purchase price is more expensive, as for use cost, some uses the cost ratio automobile expensive, and some price only is 1/3 of automobile, and this depends primarily on life-span and local oil, the electricity price lattice of battery.

The publication document as:

Chinese patent application 201110078342.1 relates to and has the electronlmobil 10 that at least one energy supply for electronlmobil 10 provides the independent energy feeding unit 11 of additional electrical energy.At least one independently energy supply unit 11 form installable energy supply unit 11 in fixing or detouchable hook attachment for trailer 12,13 scopes.

Chinese patent application 201210129551.9 provides a kind of electronlmobil, belongs to the transportation means technical field.If it has solved the problem that the unstable electrical fault vehicle of existing electric automobile during traveling just runs out of steam fully.This electronlmobil comprises vehicle frame, and the vehicle frame front end is positioned with two front-wheels, and the rear end is positioned with two trailing wheels; Be fixed with electrokinetic cell system and two drive motor on the vehicle frame, one of them drive motor is by speed changing structure and two front-wheel mechanical attachment, another described drive motor is by speed changing structure and two trailing wheel mechanical attachment, and two described drive motor all electrically connect by electric machine controller and electrokinetic cell system; Electronlmobil also comprises entire car controller, and described two electric machine controllers all electrically connect with entire car controller.Therefore this electronlmobil front and back wheel individual drive and independently controlling carries out f-w-d, back-wheel drive and four wheel drive according to the control policy in the entire car controller, makes automobile satisfy the requirement of different road conditions, simultaneously optimization system efficient.

201010116774.2 1 kinds of electronlmobils of Chinese patent application comprise shell, chassis, wheel, seat and operating console; The edge on described shell and chassis is fixed, and forms the vehicle body of electronlmobil; Described wheel is installed on the axletree on chassis; Described seat and operating console are positioned at vehicle body, are arranged on the chassis; Described operating console is arranged at the front portion on chassis, and middle position is provided with bearing circle; Described seat is elongate in shape over against the bearing circle setting, extends to the tail end of vehicle body.Adopt the many people of straddle-type to carry the sitting posture design, in the wheelbase of 1700mm, can ride and take 4-5 people, utilized fully the Ride Style of straddle-type to save the interior space of car.Take before and after riding the mode in-line, thereby can in the space of minimum, take maximum people, greatly reduced the size of vehicle body, alleviated the weight of car load, thereby increased the continual mileage of battery under limited vehicular energy of electronlmobil.
