Description
Technical field
The present invention relates to a kind of quick electrical changing station and battery box replacing method thereof of electric automobile battery box, belong to the supporting technology field of electronlmobil.
Background technology
Automobile is that human society has brought convenience, has become the indispensable important vehicle of human society daily life.In Global Auto industry fast development, two extremely serious negative effects have also been brought: petroleum-based energy crisis and increasing environmental pollution.The automobile overwhelming majority of travelling in the present society adopts fuel oil as power, and oil resources are a kind of non-renewable energy, and oil production in the last hundred years, consumption and use all present the trend of develop rapidly.The sustainable development of auto-industry has been subject to baptism and the challenge of the factors such as the energy, environment.National governments and relevant enterprise are all generally recognized: energy-saving and emission-reduction are main directions of future automobile technical development, and Development of EV is the optimal path that solves energy shock and environmental pollution two hang-ups.So adopting the automobile of new forms of energy is the trend of future development, wherein pure electric automobile has the advantage of environmental protection because of it, will become the leading of future world automotive field.
Electronlmobil be with vehicle power as power, travel with power wheel, meet the self-propelled vehicle of the requirements of arteries of communication, legislative control on safety.Now, in urban taxi and individual family, use electronlmobil to obtain quite general approval and application in the big city of American-European Countries and Japan.Yet because the restriction of the battery-charging station on the road, the course continuation mileage of pure electric automobile is subject to severely restricts, also is the obstacle that hinders its development.Although succeeded in developing now the fast charge technology, it has destructive effect to battery, and this charge mode also is unfavorable for regular detection, maintenance and the maintenance of battery, also affects and shortens battery.The shortcut of another kind of fast charge is: change battery, can realize like this replenishing fast the energy, can detect the used batteries under changing, maintain and safeguard again, improve battery.So the electrical changing station of construction electric automobile battery box is an effective way that solves the battery car flying power in the city.
At present, it mainly is to change electricity in automobile both sides horizontal direction that electronlmobil is changed the battery box mode, and for example " power battery of electric vehicle fast replacement system " (Chinese invention patent application publication number CN101284524A), " a kind of vehicle mounted dynamic battery changing system " are (CN101214814A) and " device for rapidly replacing battery of electric automobile " situation about (CN101564984A) introducing.Because the battery box weight of the pure electric sedan of driving more than 150 kilometers will reach more than 200 kilograms, for counterweight reasonable, its battery box is not mounted in front, the tail two ends of vehicle, can only be installed in the bottom side of vehicle middle passenger seat, for example " a kind of electronlmobil " (Chinese utility model patent Granted publication CN201195491Y).Also Introduction of Literatures is arranged this structure automobile change method for electrically, for example: " automatic battery replacing system of electronlmobil and the method for automatically changing batteries of electric automobile " (CN101870284A) and " a kind of fast-assembling quick-change system of batteries of electric automobile and fast-assembling quick change method " (CN101559758A), but, the former can only carry out coarse positioning to battery by battery change system, can not realize accurate loading and unloading.Although the latter's specific design adapter plate on the electronlmobil, power brick, body platform and installation process, do not mention and how to realize that lifting device follows the accurate location of electronlmobil bottom battery case.Therefore, existing domestic technique just adopts blindmate to change the poor reliability of loading and unloading battery case to this type of battery.
The Better place company of the U.S. has proposed the technical scheme of the fast quick change electricity of battery box, and has been applied.Its system mainly is provided with: vehicle locating platform, change electric equipment, battery box load transfer device and battery box storage vault.The core of changing electric equipment is that employing can be at the mobile duplex waggon of a strip transmission line, and for delivery of full electric battery box and power shortage battery box, the unloading of battery box and installation are all finished by a fixing liftable lifting equipment.Although the whole process implementation of this technical scheme automation, its problem is: travel line distance is oversize, and the space that the place takies is large, the cost of investment of whole station is high, is unfavorable for promotion and application.

(6) carry the power shortage battery box: the double-deck scissors mechanism that platform is changed in the battery box lifting descends, this power shortage battery box is returned to the above-mentioned three-dimensional initial position of adjusting member, thereby drop on the battery box carriage roller-way on this lifting replacing platform, then be transported to inboard roller-way, taken away by piler, put into the battery box storage rack and charge;
(7) carry full electric battery box: be temporarily stored on the roller-way of the outside full electric battery box by outside roller-way be transported to lifting change platform directly over;
(8) be loaded with full electric battery box: the battery box lifting change platform recovering step (4) record laterally, vertically move the anglec of rotation of displacement and the rotation positioning platform of platform, again by double-deck scissors mechanism lifting, to expire electric battery box lifts and is loaded on the electronlmobil, behind the locking of the electromechanical locks in automobile battery box, the battery box lifting is changed platform and is descended, so that should recover its initial position by three-dimensional adjustment member, finish the replacing of battery box; The electronlmobil departures;
(9) finish fast quick change electricity all operations were, be in and wait for next time and change electricity condition.
