Description

The batteries of electric automobile case

Technical field

The utility model relates to a kind of electric automobile accessory, is specifically related to a kind of batteries of electric automobile case.

Background technology

At present, new forms of energy pure electric automobile (commercial car) all adopts the mode of directly filling that vehicle is carried out quick charge, and it all is to be directly installed on car body inside that vehicle uses battery case, and the stability of using for vehicle and the maintenance and the fail safe of battery all can not better controlled.In order to shorten the charging interval, vehicle safety is improved, will adopt car body fast changing battery form to replace filling form soon, need develop a kind of novel battery case thus.

The utility model content

Goal of the invention: in order to overcome the deficiency that exists in the prior art, the utility model provides a kind of being convenient to that Vehicular battery is carried out quick-replaceable batteries of electric automobile case.

Technical scheme: for solving the problems of the technologies described above, a kind of batteries of electric automobile case of the utility model comprises interior box assembly and housing assembly, and said housing assembly comprises the housing bottom framework, and housing bottom framework bottom is provided with first directive wheel and second directive wheel; Box assembly comprises interior box body in said, and interior box body bottom surface is provided with the first guiding base plate and the second guiding base plate; Said first directive wheel rolls with the first guiding base plate and cooperates, and second directive wheel cooperates with the second guiding base plate; The box body both sides are respectively equipped with mechanical lock in said, and said housing bottom framework both sides are respectively equipped with the dead bolt fixed insulation cover that is used for fixing the mechanical lock dead bolt.

For the ease of bringing out interior box body, said interior box body the place ahead is provided with little handle and big handle.

Said first directive wheel middle part along the circumferential direction is provided with groove.

Beneficial effect: the batteries of electric automobile case of the utility model, through with structural module, be convenient to make dismounting, be applicable to various new forms of energy pure electric automobiles (commercial car) vehicle; Through a large amount of use sheet metal structural spares, both can reduce cost, enhance productivity, can guarantee product quality and consistency again, the error of avoiding artificial processing to produce, better fit is changed the quick replacing of electric equipment to battery case; Interior box assembly can avoid battery drain to cause the potential safety hazard of the charged initiation of car body with the insulating Design of outer box assembly; The accuracy that the guide frame of optimizing can guarantee to change electrical interface.
