Abstract
The utility model relates to an electric power use safety device for an electric automobile soaked in water, in particular to a power battery protective device of an electric automobile. The power battery protective device comprises an outer box body (4) contained in a power battery box (1), an upper cover (3) covered on the outer box body and a front door (5) positioned on the front side of the outer box body, wherein the outer box body, the upper cover and the front door form a totally-enclosed metal box. The power battery protective device provides a totally-enclosed metal box structure for the power battery box and electrodes thereof, and equipotential bodies are formed in the water through metal plates or metal meshes, so that the personal security is effectively protected.
Description
Technical field
The utility model relates to the Electrical Safety device after the electric automobile immersion, relates in particular to a kind of electric automobile power battery protector.
Background technology
In the face of the energy shortage and the ecological deterioration problem that are on the rise, seek society, economy and resource, environment is mutually promoted and the sustainable development pattern that develops in harmony is becoming worldwide trend.Under this background, electric vehicle engineering becomes a big focus in automotive research field, and the Electrical Safety problem after the car load immersion is the emphasis of paying close attention in many ways always.
Electric automobile immersion in a single day at present, electrokinetic cell will form an electric field considerably beyond human safety voltage 7.5V under water, will directly threaten personal safety.Existing safeguard procedures are to adopt the sealed type design for electrokinetic cell, and water is not advanced in the electrokinetic cell, but the electrokinetic cell positive and negative electrode is still exposed outside, thereby cause personal security hidden danger.
Summary of the invention
The purpose of this utility model is to provide a kind of electric automobile power battery protector; this protector gives dynamic battery box and the totally enclosed metal box structure of electrode thereof; utilize metallic plate or wire netting in water, to form the equipotential body, thereby effectively protect personal security.
To achieve these goals, the utility model adopts following technical scheme:
A kind of electric automobile power battery protector is made up of the outer case of taking in dynamic battery box, the Qianmen that is placed on the loam cake on the outer case and is positioned at the outer case front side, and described outer case, loam cake and Qianmen constitute totally-enclosed metal box.
Described outer case, loam cake and Qianmen are made by metallic plate.
Described outer case, loam cake and Qianmen are made by wire netting.
Described Qianmen and battery case are formed one, and the soft iron dish is housed on the Qianmen, are convenient to the robot magnechuck and inhale mutually with the soft iron dish.
The utility model is by adopting totally enclosed metal box structure to dynamic battery box and electrode thereof, utilize wire netting or metallic plate in water, to form the equipotential body, electric automobile whole is in case immersion, because the electric field that active body such as electrokinetic cell, electrode forms will be enclosed in this shielding case body, and be an equipotential electric field outside this casing, can on human body, not produce voltage difference, promptly can not influence personnel's personal safety under water, thereby effectively guarantee personal safety.
Description of drawings
Fig. 1 is the utility model electric automobile power battery protector structural representation (vertical view);
Fig. 2 be among Fig. 1 A-A to view;
Among the figure: 1 dynamic battery box, 2 poles, 3 loam cakes, 4 outer case, 5 Qianmens, 6 end lock dog, 7 tapered ends, 8 outer case rollers, 9 battery case roller grooves, 10 soft iron dishes, 11 magnechucks.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, Fig. 2, a kind of electric automobile power battery protector is made up of the outer case 4 of taking in dynamic battery box 1, the Qianmen 5 that is placed on the loam cake 3 on the outer case 4 and is positioned at outer case 4 front sides; In the bottom of outer case 4 roller 8 is housed, battery case 1 bottom is provided with roller groove 9, and battery case 1 enters in the outer case 4 along outer case roller 8 through battery case roller groove 9; The both sides inner face front end of outer case 4 is equipped with lockable mechanism, and described lockable mechanism includes the tapered end 7 of elastic telescopic, and only lock dog 6 is housed on the battery case 1, and lockable mechanism tapered end 7 can only pin battery case to be ended lock dog 6 battery case 1 is locked in the outer case 4; On the rear side inner face of outer case 4 pole 2 is housed, battery case 1 contacts with pole 2 after entering in the outer case 4, thereby battery case 1 internally-powered electricity is flowed to electric automobile; Described outer case 4, loam cake 3 and Qianmen 5 constitute totally-enclosed metal box, promptly constitute shielding case body, and outer case 4, loam cake 3 and Qianmen 5 are made by metallic plate, and perhaps outer case 4, loam cake 3 and Qianmen 5 are made by wire netting.One is formed with battery case 1 in described Qianmen 5, on the Qianmen 5 of battery case 1 soft iron dish 10 is housed, the magnechuck 11 of being convenient to robot is inhaled mutually with soft iron dish 10, by the effect of electromagnet suction, battery case 1 is promoted or withdraw from outer case 4, finish the replacing of electrokinetic cell.
Electric automobile power battery protector of the present utility model, in case whole electric automobile immersion, because the electric field that active body such as electrokinetic cell, electrode (pole) forms will be closed in this shielding case body, and be an equipotential electric field outside this casing, can on human body, not produce voltage difference, promptly can not influence personnel's personal safety under water.
It below only is preferred embodiment of the present utility model; be not to be used to limit protection range of the present utility model; therefore, all any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
