Abstract
The utility model discloses an upper cover device used on an electric vehicle storage battery, which comprises an upper cover body and a cover sheet, wherein a plurality of air overflowing holes are formed on the upper cover body, a cover valve cap is arranged in the air overflowing holes, a plurality of exhaust passages are formed on the cover sheet, and the exhaust passages are communicated with the air overflowing holes. Because the exhaust passages are formed on the cover sheet, when the cover sheet is pasted, trichloromethane is sprayed on the surface of the upper cover body, the flowability of the trichloromethane on the smooth cover surface is poor even though the trichloromethane is liquid, the exhaust passages on the cover sheet can not be blocked regardless of the corrosion degree of the surface of the upper cover body, and the bulging deformation of the battery can not be caused. Thereby, the rejection rate of the battery can be reduced. The maintenance times can be reduced, the quality of the whole storage battery can be improved, a large amount of maintenance cost and the caused maintenance time can be saved for users, and thus, the reliability of the storage battery is also improved.
Description
Technical field:
The utility model relates to the storage battery field, more specifically to a kind of capping device that is used for electromobile battery.
Background technology:
See accompanying drawing 1 ~ 2, the capping device of existing electromobile battery, be by upper cover body A, cover plate B constitutes, cover plate B is bonded on the upper cover body A, form several air leakage holes A1 on the described upper cover body A, be equipped with in the described air leakage hole A1 and cover bonnet C, also has exhaust duct A2 on the upper cover body, described exhaust duct A2 communicates with air leakage hole A1, its weak point is: battery has gas to overflow from air leakage hole A1 in inside when charging, for reducing the battery dehydration lid bonnet C has been installed, cover plate B is bonded in upper cover body A to be pushed down and covers bonnet C, make its exhaust under certain air pressure, this gas is discharged through the exhaust duct A2 of upper cover body, the top and bottom of cover plate B are smooth, there is exhaust duct A2 in upper cover body A, when sticking cover plate B, need the spray chloroform on cover plate B surface, because chloroform is a liquid, so chloroform flows to the exhaust duct A2 of upper cover body A easily, thereby the ABS plastic of corrosion exhaust duct A2, and molten with cover plate B is one, causes exhaust duct to stop up, and has blocked the pressed gas discharge, cause the distortion of battery bulging, increased the scrappage of battery greatly.
The utility model content:
The purpose of this utility model is at the deficiencies in the prior art part, and a kind of capping device that is used for electromobile battery is provided, and its cover plate forms several exhaust ducts; Exhaust duct communicates with the air leakage hole of upper cover body, so just the exhaust duct phenomenon of blocking can not take place, and has guaranteed the normal exhaust of storage battery, can not cause the distortion of battery bulging.
Technology solution of the present utility model is as follows:
A kind of capping device that is used for electromobile battery comprises upper cover body, cover plate, forms several air leakage holes on the described upper cover body, is equipped with in the described air leakage hole and covers bonnet; Described cover plate forms several exhaust ducts; Described exhaust duct communicates with air leakage hole.
Described a kind of capping device that is used for electromobile battery, described exhaust duct is four.
Described a kind of capping device that is used for electromobile battery, described exhaust duct is made of straight air flue and two arc roads that are positioned at its two ends.
Described a kind of capping device that is used for electromobile battery, described two curved channels protrude into straight air flue.
Described a kind of capping device that is used for electromobile battery, described two curved channel radiuses are 6.5mm.
Described a kind of capping device that is used for electromobile battery, described exhaust duct communicates with adjacent two air leakage holes.
The beneficial effects of the utility model are:
1, because exhaust duct is molded on the cover plate, so when gluing cover plate, the spray chloroform is on the surface of upper cover body, although chloroform is a liquid, but mobile relatively poor at smooth capping chloroform, corrode the upper cover body surface in any case and also can not block exhaust duct on the cover plate, can not cause the distortion of battery bulging, thereby reduce the scrappage of battery.Reduced maintenance frequency, not only improved the quality of whole storage battery, also, also therefore promoted the reliability of storage battery for the user has saved a large sum of maintenance cost and the maintenance time that therefore produces.
2, save processing cost, with respect to the exhaust duct that processes on upper cover body, the exhaust duct that processes on cover plate is saved man-hour more, and its difficulty of processing is lower, so processing is easier to, can cut down finished cost.

Embodiment
Embodiment sees Fig. 3～6, and a kind of capping device that is used for electromobile battery comprises upper cover body 1, cover plate 2, forms several air leakage holes 101 on the described upper cover body 1, is equipped with in the described air leakage hole 101 and covers bonnet 3; Described cover plate 2 forms several exhaust ducts 201; Described exhaust duct 201 communicates with air leakage hole 101.
Described exhaust duct 201 is four.
Described exhaust duct 201 is by straight air flue 201a and two arc road 201b that are positioned at its two ends, and 201c constitutes.
Described two curved channel 201b, 201c protrudes into straight air flue 201a.
Described two curved channel 201b, the 201c radius is 6.5mm.
Described exhaust duct 201 communicates with adjacent two air leakage holes 101.The mode of communicating like this is that present embodiment provides; also can one 201 of exhaust ducts communicate with air leakage hole 101; just opened several exhaust ducts 201 like that, can certainly be that an exhaust duct 201 communicates with several air leakage holes 101, so also in protection range of the present utility model more.
Operation principle: in the time of use, the spray chloroform is at the surperficial face of upper cover body 1 earlier, be stained with cover plate 2 then, because exhaust duct 201 is molded on the cover plate 2, so no matter the chloroform capping that how to corrode upper cover body 1 can not blocked the exhaust duct 201 of 2 of cover plates yet, just can freely not cause the distortion of battery bulging yet, thereby reduce the scrappage of battery because of pressed gas row is logical.
