Specific embodiment

It is described in detail babinet according to the present utility model with reference to the accompanying drawings.

As shown in Figures 1 to 5, babinet according to the present utility model includes：Upper cover 1 has upper perimeter wall 11 and roof 12；Institute Stating babinet and further including can absorb water and the condensate water-proof component 2 of water lock, be adhered to the inner surface of upper cover 1, wherein, condensate water-proof group At least part of part 2 covers the entire inner surface of the roof 12.

In babinet according to the present utility model, be bonded in upper cover 1 can absorb water and water lock condensate water-proof component 2 and At least part of condensate water-proof component 2 covers the entire inner surface of the roof 12, effectively prevents condensed water from babinet It is in vivo on the conductive component of the underface of roof that the inner surface of the roof 12 of upper cover 1 vertically drops onto case, substantially reduces The risk of the conductive component short circuit of box house.

Condensate water-proof component 2 is there are many arrangement form, in one embodiment, with reference to Fig. 1 and Fig. 3 to Fig. 5, condensate water-proof group Part 2 includes：Every dew cotton 21, there is wall 211 and be connected to the upper wall 212 of wall 211, the outer surface of wall 211 is adhered to The inner surface of the upper perimeter wall 11 of lid 1 and the entire inner surface for covering upper perimeter wall 11, the upper surface of upper wall 212 are adhered to upper cover 1 The inner surface of roof 12 and the entire inner surface for covering roof 12；And waterproof in the form of sheets, is adhered to every dew cotton 21 through film 22 Upper wall 212 lower surface and cover every dew cotton 21 upper wall 212 entire lower surface.In babinet according to the present utility model In, it is super-strong moisture absorbing high molecular material described below every dew cotton 21, there is stronger water suction and water lock, water absorption is itself 4-8 times of weight, waterproof through film 22 there is moisture vapor permeable and liquid-tight state water (in the state of steam, particle water It is very tiny, according to the principle of capillary moving, the opposite side that waterproof penetrates film 22 can be smoothly penetrated into, is showed so as to which vapour occur As；After moisture condensation becomes droplet, particle becomes larger, since the effect of droplet surface tension (" is pullled anti-mutually between hydrone Weighing apparatus "), hydrone cannot smoothly depart from droplet and penetrate into opposite side of the waterproof through film 22, that is, prevent the reversed of water Infiltration occurs).Therefore, when the in vivo vapor of case rises in the receiving space S of babinet, can penetrate waterproof through film 22 and every Reveal cotton 21, form droplet since condensation occurs for the temperature difference when vapor is contacted with the upper cover 1 of babinet, droplet is bonded in upper cover Being absorbed every dew cotton 21 together, and droplet will not be oozed out from waterproof through film 22, when the condensed water every the dew latching of cotton 21 reaches full And state, extra condensed water can flow downward along the wall 211 every dew cotton 21, condensed water is only along the upper of upper cover 1 at this time Peripheral wall 11 flows downward, and will not drop onto on the in vivo battery modules M of case.In addition there is heat-insulating capability every dew cotton 21, can subtracts The temperature difference inside and outside few babinet, reduces condensation；Also play an important role of that damping can reduce exterior vibration to battery with after dew cotton 21 The destruction of module M.In another embodiment, condensate water-proof component 2 includes：Every dew cotton 21, in the form of sheets, the top of upper cover 1 is adhered to The inner surface of wall 12 and the entire inner surface for covering roof 12；And waterproof in the form of sheets, is adhered to every dew cotton 21 through film 22 Lower surface is simultaneously covered every the entire lower surface of dew cotton 21.In this embodiment, film 22 is penetrated with identical with waterproof every dew cotton 21 Shape is sheet, and is only bonded on the inner surface of roof 12 of upper cover 1, when excessive condensed water is from every dew cotton 21 When edge is precipitated, condensed water can downwards slide along the upper perimeter wall 11 with the upper cover 1 every dew 21 EDGE CONTACT of cotton, be prevented from Condensing drip falls in vivo battery modules M of case described below the upper surface of, avoids the short circuit of battery modules M.

Babinet further includes：Lower box 3, is fixed on the lower section of upper cover 1, and lower box 3 has lower peripheral wall 31 and bottom wall 32.
