A corrugated connecting tube or an opening unit should be equipped with.The present apparatus can effectively be made in battery pack by waterproof ventilated membrane
Portion's gas can normally circulate with atmosphere, so that balancing battery packet inner and outer air pressure, is allowed under the conditions ofs height above sea level or internal-external temperature difference etc.
It there will not be risk of explosion；Meanwhile the waterproof ventilated membrane can prevent dust, ponding etc. from entering battery pack.When being sent out in battery pack
Raw failure conditions and when releasing a large amount of gas, gas can heave upwards waterproof ventilated membrane, thus opening unit puncture it is anti-
Water ventilated membrane, battery pack internal gas quickly diffuse in atmosphere from the corresponding ventilation area of opening unit, and explosion is avoided to send out
It is raw.
The section of the corrugated connecting tube is in down big up small, and corrugated connecting tube and body interior bearing are equipped with sealing
Circle.
The height that the height of the corrugated connecting tube is higher than body upper surface is even opened at the top of the corrugated connecting tube
Mouth can extend to interior high-order or other positions that should not have water and dust, so that dust, ponding be avoided to enter in ontology
Block waterproof ventilated membrane.
The opening unit includes half frame shape protection cap of bottom opening and is fixed on inside protection cap and extends downwardly
Pricker, bottom and the ontology of the protection cap fix, and the side wall of the protection cap is equipped with gap, under normal circumstances, pricker
Bottom have between waterproof ventilated membrane upper surface one section it is small at a distance from, avoid waterproof ventilated membrane from leading to its quilt because of miniature deformation
It punctures；Certainly, when causing danger, waterproof ventilated membrane heave upwards will soon with contact and be punctured at the top of pricker, this away from
From generally in 0.5~2mm or so range.
The body interior is located at the side that waterproof ventilated membrane is not provided with corrugated connecting tube and opening unit, is equipped with metal
Shield, the periphery welding of the waterproof ventilated membrane on the body, and are clamped by ontology and shelter-clad, the demarcation plate
Outer end is fixed with shelter-clad, and the upper surface of demarcation plate is bonded with waterproof ventilated membrane and is divided into waterproof ventilated membrane at least a
Ventilation area.
The ontology sidewall bottom is equipped with the mounting groove being recessed upwards, and is pressed into rubber ring inside the mounting groove.If
Set rubber ring, it is ensured that the installation leakproofness of ontology and battery pack.
The body peripheral is equipped with multiple mounting holes, and is pressed into the metal for promoting bulk strength in the mounting hole
Inserts.
Compared with prior art, the beneficial effects of the utility model are embodied in following several respects:
1, enhancing function reduces security risk: solving existing product and is immersed in the water not ventilating in battery pack and carries out pressure
The shortcomings that balance.
2, diversification integrated functionality: realizing anti-riot vent valve waterproof ventilated membrane compartmentalization and be divided into 2 or multiple, can
To realize the pluralistic functions such as ventilative, dust-proof, waterproof, anti-pollution simultaneously.
3, easy for installation: corrugated connecting tube can be installed with any angle, can flexibly be dismounted.
4, compact design: the region equipped with gas guide pipe only accounts for waterproof ventilated membrane sub-fraction, is able to satisfy battery pack
Any arrangement
5, cost is reduced: the function that multiple products are realized, it is integrated, reduce investment and the wasting of resources.
