Along with the development of society, isolation technics---this historic innovative idea is born in China for car electricity, has created brand-new electronlmobil power supply mode, by the convertibility of on-vehicle battery, thereby has walked around the above-mentioned bottleneck of battery.Yet, the solution of part bottleneck, incident is that more practical problems is difficult to solve, be mainly: at first, as everyone knows, power resources as electronlmobil, its on-vehicle battery weight is very large, even may take about half of vehicle body total mass, this just causes it to be expert on the one hand sailing, equal electronlmobil and carrying a car battery running, had a strong impact on its actual energy efficiency, on the other hand, the on-vehicle battery of weight like this, general manpower can be described as can't finish battery altering work, and this just often needs to rely on the next collaborative or separately operations such as configure dedicated robotic arm, and its robotic arm use and maintenance cost is high, single changes long problem of electricity time and can't be properly settled always; Secondly, existing no matter which kind of electronlmobil, its battery is placed to be by this car is vehicle-mounted and is realized, for realizing the flying power of vehicle, certainly will need to increase capacity of cell, this just need to realize by increasing the battery volume, and the increase of battery volume, certainly will improve again the quality of battery, affect again on the contrary complete vehicle weight, thereby further cause the acceleration of battery electric power to run off.How under the prerequisite that does not affect the deadweight of this car, to provide a kind of flying power to fill by force and change short electronlmobil of electricity time, become the significant problem of the world structure that can change existing electronlmobil.

Summary of the invention

The purpose of this invention is to provide a kind of simple in structure and working stability failure-free car electric separation type electronlmobil, it can not affect even reduce its flying power of Effective Raise under the prerequisite of automobile self load.

For achieving the above object, the present invention has adopted following technical scheme: a kind of car electric separation type electronlmobil, comprise body shell and hang on the body shell and with its formation and draw the external vehicular component that is loaded with battery of relation, be provided with traction termination and power supply termination on the external vehicular component, the traction end that relative set cooperates with it on the described body shell and power end; Described external vehicular component is the passive type traction component, be furnished with on the described external vehicular component wheel body and with ground between form to roll and to cooperate.

In fact, the present invention is with reference to present train hitch structure: independent locomotive engine possibly can't carry too much weight, and can be carried lot cargo and be carried out long-distance transportation by the railway carriage that locomotive engine draws.The present invention also is so, by said structure, because the weight of external vehicular component is fully by the wheel body on it or perhaps follower institute support, and is drawn by body shell, thereby has highlighted the locomotive engine pull effect.The weight of battery, energy contradiction weaken greatly, like this, selection to the battery kind no longer is subjected to its volume and weight constraints, even can directly select the battery of more volume and Geng Gao weight to satisfy its long distance travel demand, and the weight of vehicle own is not produced any impact; In addition, because body shell forms the traction relation with external vehicle-mounted inter-module, that is to say, during actual the use in addition can be directly by the dismounting traction end and draw the termination, thereby reach the purpose that manpower is directly changed battery, its operation is very convenient and swift.Because vehicle body no longer carries the on-vehicle battery that battery only needs the carrying lower weight in other words, cause the deadweight of this car greatly to be reduced, also just having realized can be in the purpose that does not affect even reduce its flying power of Effective Raise under the prerequisite of automobile self load, it is simple in structure and working stability is reliable, and market outlook are wide.
