Abstract
The utility model provides a kind of air releasing device of battery case, comprise the annular groove be arranged on battery case lid, the central authorities of groove are provided with the bleeder port having and ventilate and lead the way, the top of bleeder port is provided with seal cover, the top of bleeder port covers and ventilation is led the way closed by seal cover completely, the opening part of groove is provided with enclosing cover, and enclosing cover and recess sidewall have the stressed joint in space, forms enclosing cover exhaust passage between enclosing cover and recess sidewall.This device, by rubber seal lid, reaches the technique effect of sealing, instantaneously exhaust, easily Installation and Debugging.
Description
Technical field
The utility model relates to a kind of safeguard construction of battery case.
Background technology
There is battery case to be function of not losing heart in existing common technology, have certain potential safety hazard.Now according to the requirement of national safety standard office, in order to prevent after batteries produce heat because of the excessive caused blast of pressure, require to arrange a not only sealing but also can the device of degassing function, and will be vented instantaneously, and will installment and debugging be facilitated.Fig. 1 and Fig. 2 requires currently used two kinds of technical schemes to realize this, on the sidewall of cell box shell, depression is provided with in Fig. 1, gland 12 is provided with in depression, ventilation guiding 11 is provided with in gland 12, ventilation lead the way 11 bottom be fixed with polytetrafluoroethylene breathable cloth 13 by plain washer 14, the advantage of this structure need not be debugged (having chosen required polytetrafluoroethylene breathable cloth), easy for installation; Shortcoming is: blow-by is easily leaked, and can not be vented instantaneously, and ventilation is led the way and easily entered dust, and outer exhaust has obstacle, and can not re-use, cost is high; Fig. 2 arranges ventilation to lead the way 21 on battery case lateral wall, and ventilation is led the way in 21 and arranged adjusting nut 22, spring 23, chock plug 24 and sealing ring 25.The advantage of this structure is: sealing, is vented instantaneously, outer tunnel smooth in exhaust, can re-uses; Shortcoming: need debugging, assembly difficulty is high, needs adjusting nut, spring, chock plug to link together, and cost is high.
Utility model content
In order to solve the above problem existed in background technology, the utility model provides a kind of air releasing device of battery case, and this device, by rubber seal lid, reaches the technique effect of sealing, instantaneously exhaust, easily Installation and Debugging.
For achieving the above object, the utility model adopts following technical scheme:
A kind of battery case air releasing device, comprise the annular groove be arranged on battery case lid, it is characterized in that, the central authorities of groove are provided with the bleeder port having and ventilate and lead the way, the top of bleeder port is provided with seal cover, and the top of bleeder port covers and ventilation led the way closed by seal cover completely, and the opening part of groove is provided with enclosing cover, enclosing cover and recess sidewall have the stressed joint in space, form enclosing cover exhaust passage between enclosing cover and recess sidewall.
Described enclosing cover comprises upper cover, and the both sides lower portion of upper cover is extended with side seal, defines stage portion between side seal and upper cover, forms the tight fit leaving space between stage portion and the sidewall of groove.
Described seal cover is made up of soft material.
Described soft material is rubber, plastics or rubber and plastic.
The beneficial effects of the utility model are: utilize a rubber seal lid, by the structure that he is good, reach sealing, instantaneously deflation area and outer smooth gas discharge.Easy installation, does not debug, and re-uses, the advantage that cost is low.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated
Fig. 1 is the bleed structure adopting breathable cloth in prior art;
Fig. 2 is the bleed structure adopting spring in prior art;
Fig. 3 is the structural representation of the utility model embodiment 1;
Fig. 4 is the connection detail at A place in Fig. 1;
Fig. 5 is the structure chart of enclosing cover in Fig. 3.
Embodiment
Illustrate below in conjunction with accompanying drawing and with embodiment, the utility model to be further described:
Embodiment 1
As Fig. 3, shown in 4, the upper cover 10 of battery case is provided with the groove 9 that annular caves inward, the central authorities of groove 9 are provided with bleeder port 5, the bottom surface of groove 9 is given prominence on the top of bleeder port 5, the middle part of bleeder port 5 leads the way 1 for the ventilation run through, the top of bleeder port 5 is provided with rubber closure 2, the top of bleeder port 5 covers and ventilation is led the way and 1 to close by rubber closure 2 completely, the opening part of inside groove 9 is provided with enclosing cover 3, enclosing cover 3 has the structure as Fig. 5, comprise upper cover 31, the both sides lower portion of upper cover 31 is extended with side seal 32, side seal 32 has certain distance apart from the termination of upper cover 31, stage portion 33 is defined thus between side seal 32 and upper cover 31, when enclosing cover 3 is arranged on the opening part of groove 9, the stage portion 33 of enclosing cover 3 and the sidepiece 6 of groove 9 form tight fit, be formed with enclosing cover exhaust passage 4 between stage portion 33 and sidepiece 6 simultaneously.
When battery-heating generation gas reaches 10Kpa to 30Kpa, he can flick rubber closure 2 instantaneously, and gas battery can produced to be led the way 1 discharge from ventilation, then goes out from enclosing cover exhaust passage 4, such pressure reduced in battery case, terminates battery explosion.
It will be recognized by those skilled in the art, under the prerequisite not departing from protection scope of the present invention, various amendment, change and combination can be carried out to above-mentioned execution mode, and think that this amendment, change and combination are within the scope of originality thought.
