SEALED ELECTRIC BATTERY HOUSING
A two-piece electric battery housing includes a lower housing and an upper housing. An EPDM seal to which a metal frame is attached is inserted between the lower housing and the upper frame to ensure good water-tightness of the obtained housing.
1 - 10 . (canceled)
11 . An electric battery housing configured to house at least one module of a battery, said housing being produced in two parts, comprising:
a bottom housing having a flat junction edge and a top housing having a flat junction face, the bottom housing and the top housing being configured to come to bear against one another to form the housing via placement of the flat junction edge in contact with the flat junction face, an EPDM seal being inserted between the flat junction edge and the flat junction face to render the housing seal-tight,
wherein a metal frame is fixed to the EPDM, and the assembly composed of the EPDM seal and the metal frame is inserted between the flat junction edge of the bottom housing and the flat junction face of the top housing.
12 . The electric battery housing as claimed in claim 11 , wherein, on the flat junction edge, the EPDM seal occupies a central position and the metal frame occupies an off-centered position.
13 . The electric battery housing as claimed in claim 12 , wherein the flat junction edge of the bottom housing has several fixing points configured to cooperate with complementary fixing points of the top housing, said fixing points emerging from the junction edge by being aligned along a longitudinal and central axis of said junction edge, and the EPDM seal passes around said fixing points by gripping them.
14 . The electric battery housing as claimed in claim 13 , wherein the EPDM seal grips the fixing points in such a way that said fixing points are aligned along a longitudinal and central axis of said seal.
15 . The electric battery housing as claimed in claim 11 , wherein the EPDM seal is overmolded on the metal frame.
16 . The electric battery housing as claimed in claim 11 , wherein a total length of the metal frame is less than or equal to the total length of the EPDM seal.
17 . The electric battery housing as claimed in claim 16 , wherein the total length of the metal frame is strictly less than that of the EPDM seal, so that said metal frame appears discontinuous along said EPDM seal.
18 . The electric battery housing as claimed in claim 17 , wherein the EPDM seal has zones without any metal frame, and said zones each comprise a main segment linking two zones having the metal frame, and at least one secondary segment crossing the main segment by being at right angles thereto.
19 . The electric battery housing as claimed in claim 18 , wherein each zone of the EPDM seal which is without any metal frame has three parallel secondary segments crossing the main segment by being at right angles thereto.
20 . The electric battery housing as claimed in claim 11 , wherein the metal frame is produced in a metal to be chosen from among steel and aluminum.
