Description
Affiliated technical field
The utility model relates to the improvement of electronlmobil
Background technology
Electronlmobil has had the history in more than 100 year.Before fuel-engined vehicle occurs, just electronlmobil has been arranged, along with the continuous development of fuel-engined vehicle, gradually electronlmobil has been extruded the arena of history.To nineteen seventies, because the generation of energy shock, and people just light for the exploitation enthusiasm of electronlmobil again to the pay attention to day by day of environmental protection.In the last thirty years, the scientific research institution of many countries and many transnational automobiles enterprise in the world, all electronlmobil is researched and developed sparing no effort, the great amount of manpower financial resources have been dropped into, a lot of technical progress have also been obtained, but its effect can not be satisfactory, fails to develop a kind of next for practical electronlmobil all the time.Based on above-mentioned situation, the auto-domain giant of the U.S. and Japan declares to abandon the exploitation of pure electric automobile one after another.Its concrete manifestation is: the range ability after 1) race not far is once charged is short, and generally at 100-150Km, out of reach can drop into requirement of actual application; 2) according to the data introduction of the relevant U.S., the price of an electronlmobil is 80,000 dollars to the cost height one by one, and the price of the electronlmobil of domestic certain factory is 120,000 yuan.But do not comprise 400,000 yuan storage battery; 3) charging duration long was generally 6-8 hour.Also once had data to introduce the technology of fast charge, and charging duration can be reduced in one hour, but the equipment complexity is also high to the requirement of storage battery.Just because of the existence of above-mentioned reason, and in short-term, be difficult to solve, AM General company announces no longer to provide the letting of electronlmobil, removes and protects
Based on above-mentioned situation, be necessary to provide a kind of new solution, overcome the deficiency that existing electronlmobil exists.
Summary of the invention
The purpose of this utility model is, overcome the defective that existing electronlmobil exists, a kind of new general design idea and concrete solution are provided, use the performance that improves electronlmobil, reduce its cost, and the service guarantee in the solution use, for electronlmobil enters the commercial operation support that provides the necessary technical.
The utility model can be realized by the following technical solutions: it comprises a kind of electronlmobil of novel structure at least: can direct applied part in the orthodox car, the part that partial sum by innovation transformation increases newly, this three part are organically in conjunction with constituting special-purpose electronlmobil platform.This special-purpose electronlmobil platform is by increasing income and decreasing expenditure, realize the imagination of " with weight displacement energy ", reduce the weight of electronlmobil, under the controlled prerequisite of curb mass, can increase considerably the carrying capacity of storage battery, increase the energy storage amount, dwindle and the gap of fuel-engined vehicle on energy storage, on vehicle performance, dwindle the gap with fuel-engined vehicle, for electronlmobil enters the commercial operation support that provides the necessary technical.The utility model is in the general design part, it comprises at least: adopt new material one to make the electronlmobil vehicle body with polymer-based composite, adopting new construction one is the self-supporting body of basic design with the sandwich construction, and expansion field of application, except being used for topped and framing member, also be used to make functional component, as the reductor casing.And adopt new arrangement, adopt two-layer or three-decker.Front deck is designed to double-decker, and the upper strata is a powerhouse dome, and lower floor is a piggyback pod; Rear deck is designed to three-decker, and the upper strata is a boot compartment, and the middle level is a powerhouse dome, and lower floor is a piggyback pod.Adopt rational general layout, many-sided coordinations such as the accumulator plant of making overall plans, power configuration and driving device guarantee that the load that drives sedan-chair is not less than 55%, uses the stability that guarantees the car load operation.
Further the utility model has adopted accumulator of electric car to change fast, recover the device and the method for operation of energy storage, its principal feature is to have adopted normalized power subsystem unit or combined electrical source unit, and corresponding device thereof such as slide rail, and corresponding surface facility is as transporting the storage battery dolly, to adapt to the quick replacing of storage battery.
Further the utility model has adopted electromechanical integration power unit device, owing to adopted motor with watter cooling, actuator, the controller of motor all can be arranged on the water jacket of electrical motor, utilize the forced cooling of motor water jacket, for the high power valve heat radiation of actuator, so as to cancellation cooling fan and radiator.Motor and actuator, controller are combined into integral body, but simplified structure not only, expendable weight shortens circuit, reduces energy consumption, and minimizing takes up room, and can also simplify maintenance operation, shortens repair time.
Effect of the present utility model is significant:
1) solving on the not far problem of electronlmobil race, because the utility model has adopted the control total amount, keep under the basic unmodified prerequisite of curb mass, reduced the net weight of car load, increased considerably the storage battery carrying capacity, its carrying capacity can reach 20 times of orthodox car fuel load, has solved the contradiction of energy deficiency effectively, even adopt the lower lead-acid storage battery of energy, also can make the range ability after once charging reach the 200-250 kilometer.
2) solve on the high difficult problem of electronlmobil cost, because the utility model has adopted multinomial new construction, new equipment, up-to-date technology, simplified or cancelled the labyrinth on the orthodox car, so the cost of electronlmobil declines to a great extent, compare with external electronlmobil, cost be about its 1/10.
3) solving on the long problem of charging duration, the utility model has adopted the device and the corresponding method of operation of quick replacing storage battery, the time of replenishing the energy can be controlled at 5-10 minute, and its convenient degree can be similar or better with the oiling of orthodox car.
4) aspect motor, automatically controlled maintenance, the utility model has adopted electromechanical integration power unit device because motor, automatically controlled be an integral body, can in 30 clocks, change automatically controlled or a whole set of motor one electrical controller.This popularization for electronlmobil is very favorable, in case the fault of motor, automatically controlled aspect in use takes place, at the timely trouble-shooting of maintenance point, recovers the normal function of electronlmobil rapidly.
5) because the utility model has adopted the electrically-charged subsequently method of the on-the-spot replacing of storage battery; The charging duration of storage battery can be chosen in during the electricity consumption trough at night.During this period of time, what the power plant sent is the idle energy that is difficult to utilize, if with these idle energy utilization that is difficult to utilize, be battery charge, replace the oil in short supply that needs import,, reduce the foreign exchange expenditure alleviating the energy shortage of country, ensure national energy security, can play immeasurable effect.In addition, the electricity charge at night have only 40% of the normal electricity charge, and the economic benefit and the construction battery-charging station of encouraging investment for improving battery-charging station all can have very big facilitation.
6) the utility model employing is the electronlmobil of energy carrier with the storage battery, can not produce exhaust emission in operational process, can not pollute surrounding environment, and be very favorable for the protection The Surroundings in Cities.Even the employing lead-acid storage battery, because the way of having taked old and useless battery comprehensively to reclaim can not pollute environment yet.
