Brief description of the drawings
Fig. 1 is the battery box for electric vehicle structural representation that the utility model preferred embodiment one provides;
Fig. 2 is the battery box for electric vehicle cutaway view that the utility model preferred embodiment 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
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.
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 the cavity for placing 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.
The height of lower house 2 sides is 0.3 centimetre to 15 centimetres, is preferably 0.5 centimetre, 1 centimetre, 3 centimetres, 5 centimetres, 10 centimetres.Lower house 2 is closely enclosed within the outside of battery of electric vehicle 3, and shallow side is enough to fix one or more battery of electric vehicle 3.
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; then pasting the lateral surface of battery of electric vehicle 3 to downward-extension, behind the bottom surface of arrival lower house 2, outward stretches out 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 lower limb, 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 bottom or side immerse battery case; In the time that electric motor car is paddled, the air in upper shell 1 space can produce the high position that enough pressure stops water to enter battery case, avoids the joint at battery of electric vehicle 3 tops and electric wire 4 to be drenched, soaked.
The bottom of battery of electric vehicle 3 does not have joint or wire structure, is not afraid of wet by water.The side of lower house 2 is more shallow, while paddling, likely can intake.But these water are deposited incessantly, along with the water that rocks of battery case can be got rid of automatically.Also can on the side of lower house 2 or bottom surface, add osculum, accelerate the eliminating of ponding.
Upper shell 1 is seamless integrated molding structure, and the top of battery of electric vehicle 3 and four sides have been protected simultaneously.In the time that 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.In the time that 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 the cavity for placing battery of electric vehicle, and the lower limb of upper shell and the bottom surface of lower house are in same plane.The height of lower house side is 0.3 centimetre to 15 centimetres.
Difference is: upper shell and lower house can be made up of other fire proofing except metal, avoids battery case in the time that 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, make the use of battery of electric vehicle safer, electric motor car can travel on the darker road surface of ponding, cost is low, and processing technology is simple.
Preferred embodiment three:
