Height+20 millimeter of the height≤described battery of electric vehicle of particularly, 30 millimeters≤described lower house sidewall.
Particularly, after fastening, between the outer surface of the sidewall of described lower house and the inner surface of the sidewall of described upper shell, leave gap, the width in described gap is more than or equal to the diameter of electric wire on described battery of electric vehicle.
Further, described electric wire outside cover has protective casing; The width in described gap is more than or equal to the diameter of described protective casing.
Particularly, described upper shell and lower house are made by fire proofing.
Particularly, described upper shell and lower house are all made of metal.
On the other hand, the present invention is by the following technical solutions:
An electric vehicle battery device, comprises battery of electric vehicle, and described battery of electric vehicle outside cover has above-mentioned battery case.
The upper shell of battery box for electric vehicle of the present invention is the box-like body of an opening; the top of battery of electric vehicle and four sides are all shrouded; the high position (first half) that air pressure while paddling in upper shell can stop water to enter battery case, the safe handling of protection battery.Battery case is made by fire proofing, avoids battery to catch fire and causes car load burning.Between upper shell and lower house, leave gap, possess airing function, can in time the hydrogen overcharging be discharged, avoid occurring security incident.
The battery outside cover of electric vehicle battery device of the present invention has above-mentioned battery case, waterproof, fire prevention, can discharge in time and overcharges gas, and fail safe is better, makes electric motor car can be adapted to the road conditions of Various Complex.
Accompanying drawing explanation
Fig. 1 is the battery box for electric vehicle structural representation that the preferred embodiment of the present invention one provides;
Fig. 2 is the battery box for electric vehicle cutaway view that the preferred embodiment of the present invention one provides.
In figure, be labeled as:
1, upper shell; 2, lower house; 3, battery of electric vehicle; 4, electric wire; 5, protective casing.
Embodiment
Below in conjunction with accompanying drawing and by embodiment, further illustrate technical scheme of the present invention.
Preferred embodiment one:
This preferred embodiment provides a kind of battery box for electric vehicle.As depicted in figs. 1 and 2, this battery case comprise upper shell 1 and with the suitable lower house 2 of upper shell 1, upper shell 1 and lower house 2 are the box-like body of an opening.After fastening, upper shell 1 and lower house 2 surround for placing the cavity of battery of electric vehicle 3, and the bottom surface of the lower limb of upper shell 1 and lower house 2 is in same plane.Upper shell 1 and lower house 2 are all made of metal, and preferably use iron or aluminium.
Height+20 millimeter of the height≤battery of electric vehicle 3 of 30 millimeters≤lower house, 2 sidewalls, concrete height value can be determined according to the height of battery, can place battery of electric vehicle 3, stop water to enter battery case.
Electric wire 4 outside covers have protective casing 5.Protective casing 5 starts to protect electric wire 4 from the top of battery of electric vehicle 3, is then pasting the lateral surface of lower house 2 to downward-extension, and behind arrival bottom surface, bent outward folds upper shell 1, more upwards extremely high-order along the lateral surface of upper shell 1.
Before the inner surface of the sidewall of the outer surface of the sidewall of lower house 2 and upper shell 1, form gap, the width in gap is more than or equal to the diameter of protective casing 5.
In the moving battery box for vehicle of this preferred embodiment, the box-like body that upper shell 1 is back-off, there is larger space its inside, the top of battery of electric vehicle 3 and four sides all can be shrouded, is covered.Rainwater cannot be from top or side immerse battery case; When electric motor car is paddled, the air in upper shell 1 space can produce enough pressure and stop water from bottom, to enter a high position for battery case, avoids the joint at battery of electric vehicle 3 tops and electric wire 4 to be drenched, soaked.
Upper shell 1 is seamless integrated molding structure, and the top of battery of electric vehicle 3 and four sides have been protected simultaneously.When battery of electric vehicle 3 catches fire, upper shell 1 can stop the comburant oxygen of space outerpace, and the fire of battery of electric vehicle 3 will extinguish rapidly.
Between the inner surface of the sidewall of the outer surface of the sidewall of lower house 2 and upper shell 1, leave gap.When battery of electric vehicle 3 overcharges, hydrogen can be discharged in time from this gap, avoids hydrogen to gather and security incident occurs.
Preferred embodiment two:
This preferred embodiment provides a kind of battery box for electric vehicle, and its structure and preferred embodiment one are basic identical.Upper shell and lower house are the box-like body of an opening.After fastening, upper shell and lower house surround for placing the cavity of battery of electric vehicle, and the lower limb of upper shell and the bottom surface of lower house are in same plane.
Difference is: upper shell and lower house can be made by other fire proofing except metal, avoids battery case when battery of electric vehicle catches fire also to be ignited; Protective casing can not be overlapped in the outside of electric wire, and the crust of electric wire itself also has waterproof, anti-creeping function, and now electric wire passes from the gap in the middle of upper shell and lower house.
This preferred embodiment battery box for electric vehicle has the battery of preventing burning and causes the multiple function of safety protection such as car load burns, can paddle, good permeability, makes the use of battery of electric vehicle safer, electric motor car can travel on the darker road surface of ponding.
Preferred embodiment three:
This preferred embodiment provides a kind of electric vehicle battery device, comprises and is positioned at inner battery of electric vehicle and cover battery case externally.The structure of battery case, as described in preferred embodiment one or two, can reach a battery case high position (first half) by anti-sealing while paddling, and when battery of electric vehicle catches fire, can stop the combustion-supporting of external oxygen, the timely release hydrogen of energy during over-charging of battery, and the fail safe of use is higher.
