Definitions
- the present invention relates to a sealed electric battery housing.
- Traction batteries generally consist of a structural lower casing and a non-structural upper casing.
- the lower casing is preferably made of metal and constitutes a frame around the modules of said battery.
- the upper casing only seals against water and electromagnetic currents.
- the application CN107946515 discloses a battery box having two casings and a lip seal, intended to be inserted between said two casings.
- the seal is made of EPDM and can be installed on the lower casing of the housing. It spreads over the entire surface connecting the two casings, so that it surrounds their fixing points. This solution has, among other things, the aforementioned drawbacks during assembly.
- a casing of an electric battery according to the invention overcomes the drawbacks encountered in the state of the art.
- the subject of the invention is an electric battery casing intended to house at least one module of said battery, said casing being made in two parts, comprising a lower casing having a plane junction edge and an upper casing having a face flat junction, the lower casing and the upper casing being able to bear against one another to form the casing by means of bringing the flat junction edge into contact with the flat junction face, a seal EPDM being inserted between the planar joining edge and the planar joining face in order to make the housing watertight.
- a metal frame is fixed to the EPDM seal so as to increase the rigidity of said seal, the assembly consisting of the EPDM seal and the metal frame being inserted between the plane joining edge of the lower casing and the flat junction face of the upper casing.
- the assembly comprising the EPDM seal and the metal frame constitutes a resulting rigid seal, having a component of rigidity through the metal frame, and a sealing component through the EPDM seal.
- the metal frame is materialized by a metal rod that follows the profile of the EPDM seal. This metal frame may be present either over the entire length of the EPDM seal, or on certain sectors of said EPDM seal. The presence of this metal frame is justified, because it makes it possible to stiffen the EPDM seal, thus allowing the resulting seal to be easily and precisely handled by robots, in order to place it in its right place on the junction edge. plan of the lower case.
- the EPDM gasket would also have the shape of a rectangular frame, and the metal frame would also have the general shape of a frame. rectangular totally or partially accompanying said EPDM gasket.
- the terms “lower” and “upper” prefigure the positioning of the two casings, when the casing containing the electric battery is mounted in the vehicle.
- the EPDM seal occupies a central position and the metal frame occupies an eccentric position.
- the EPDM seal does not risk being offset from the flat junction edge, at the risk of no longer resting entirely on said junction edge, and therefore no longer ensuring a good seal between the lower casing and the upper casing.
- the flat joining edge has a length and a width, and the central position mentioned above must be considered in relation to this width.
- the flat junction edge of the lower casing has several fixing points intended to cooperate with complementary fixing points of the upper casing, said fixing points emerging from the plane joining edge being aligned along a longitudinal and central axis of said joining edge, the EPDM gasket enclosing said fixing points.
- These fixing points can for example be represented by threaded cylindrical inserts, emerging from the flat junction edge.
- the EPDM seal has openings intended for the passage of said fixing points.
- the EPDM gasket encloses the fixing points so that the said fixing points are aligned along a longitudinal and central axis of the said gasket.
- the EPDM gasket is molded onto the metal frame.
- the length of the metal frame is less than or equal to the length of the EPDM seal.
- the metal frame may have the same length as that of the EPDM seal, or have a length less than this by continuing to stiffen the EPDM seal. Indeed, it is not necessary to have a rigid frame that extends over the entire length of the EPDM seal for robots to be able to efficiently and precisely manipulate the assembly formed by the EPDM seal and the metal frame.
- the length of the metal frame is strictly less than that of the EPDM seal, so that said metal frame appears discontinuously along said EPDM seal. In this way, the metal frame is evenly distributed along the EPDM seal, without creating large areas in which the seal would not be stiffened by the metal frame.
- the EPDM seal has zones devoid of a metal frame, said zones each comprising a main segment connecting two zones having the metal frame, and at least one secondary segment crossing the main segment by being perpendicular to it.
- each zone of the EPDM seal which is devoid of a metal frame has three parallel secondary segments crossing the main segment while being perpendicular thereto. This is a “fishbone” configuration for which a main segment of the joint is crossed by three parallel secondary segments, extending perpendicularly to said main segment.
- the frame is made of a metal to be chosen from among steel and aluminum. These are materials particularly but not exclusively suitable for a metal frame intended to be fixed to an EPDM seal for the production of an electric battery casing according to the invention.
- An electric battery casing according to the invention has the advantage of being perfectly sealed while being easy and quick to manufacture, thanks to a judicious attachment of a metal frame to the EPDM seal.
- this casing has the advantage of remaining of a constant size compared to existing ones, while being perfectly sealed.
- FIG. 1 shows a perspective view of a zone of a junction edge of a lower casing for the production of a first embodiment of a casing according to the invention
- FIG. 2 shows a sectional view of the area of the junction edge of Figure 1
- FIG. 3 shows a perspective view of a zone of a junction edge of a lower casing for producing a second embodiment of a casing according to the invention
- FIG. 4 shows a sectional view of the zone of the joining edge of figure 3
- FIG. 5 shows a perspective view of a specific zone of a joining edge of a lower casing for the production of the second embodiment of a casing according to the invention, said zone showing a discontinuous metal frame.
- An electric battery of a motor vehicle comprises a casing in which modules of said electric battery are housed.
- This casing is in two parts, comprising a lower casing 2 and an upper casing, said lower casing 2 delimiting a housing intended to receive the modules of the electric battery and the upper casing acting as a cover intended to cap the casing lower 2.
- the lower casing 2 has a flat rectangular bottom and four flat side walls 3 arising on the four peripheral edges of said rectangular bottom, said side walls 3 being contiguous and perpendicular to said bottom. In this way, the lower casing 2 delimits an open parallelepipedal housing, in which the modules of the electric battery are placed.
- the four side walls 3 each have an elongated free edge 4, which is parallel to a line of junction between said wall and the bottom of the lower casing 2.
- the four side walls 3 have a constant height, said height being their dimension considered along of an axis which is perpendicular to the bottom of the lower crankcase. In this way, the four free edges of the side walls are inscribed in the same plane which is parallel to said bottom.
- Each free edge 4 is materialized by a flat surface 5 which is parallel to the bottom of the lower casing 2, the four flat surfaces 5 of said free edges 4 falling within the same plane and defining a plane junction edge 6 similar to a rectangular frame plan.
- the upper casing which is not shown in the figures, has a planar junction face intended to come into contact with the planar junction edge 6 of the lower casing 2 to form a closed casing, housing the electric battery.
- a casing according to the invention solves this problem, by attaching a metal frame to the EPDM seal, so as to obtain a resulting seal that is more rigid and therefore easier to handle.
- this metal frame is made of steel or aluminum.
- the EPDM gasket is molded onto the metal frame.
- the metal frame 51 and the EPDM seal 52 extend parallel along the plane joining edge 6 of the lower casing 2, so that said metal frame 51 is found in a central position on said joining edge 6, while the EPDM gasket 52 is found in an eccentric position on said joining edge 6.
- the expressions "central position” and “eccentric position” are to be considered with respect to the width of the joining edge 6.
- the joining edge 6 of the lower casing 2 has attachment points 7 intended to cooperate with complementary attachment points of the upper casing. These fixing points 7 appear in the form of cylindrical and threaded inserts, emerging from the junction edge 6.
- the metal frame 51 has along its length a series of circular openings 53 whose diameter is greater than the diameter of the inserts 7 embodying the fixing points. The metal frame 51 is therefore placed in a central position on the joining edge 6, so that each opening 53 accommodates an insert 7. In order to be able to pass around these inserts 7, the metal frame 53 has a significant width, which is greater to that of the EPDM seal 52. Due to this large width of the metal frame 52, the EPDM seal 52 is pushed back at the level of an end edge delimiting the width of the junction edge 6.
- the risk of such a configuration is that the EPDM seal 52 no longer rests entirely on the joining edge 6, and therefore does not ensure more with full efficiency, a good seal between the lower casing 2 and the upper casing. Indeed, as illustrated in Figure 2, a portion 54 of the EPDM seal 52 comes out of the joining edge 6, and therefore cannot rest completely against said plane joining edge 6. The consequences of such a configuration are that the EPDM gasket 52 no longer fully performs its sealing function between the lower casing 2 and the upper casing.
- central position and “eccentric position” are to be considered in relation to the width of the junction edge 6 In this way, by being in a central position, the EPDM seal 102 will certainly rest entirely on the plane joining edge 6 of the lower casing 2, and will fully ensure its sealing function between the lower casing 2 and the upper casing.
- the EPDM seal 102 has along its length a series of circular openings 103 whose diameter is greater than the diameter of the inserts 7 materializing the fixing points. The EPDM seal 102 is therefore placed in a central position on the joining edge 6, so that each opening 103 accommodates an insert 7. In order to be able to pass around these inserts 7, the EPDM seal has a significant width, which is greater than that of the metal frame 101.
- the EPDM seal 102 remains fully supported against the plane joining edge 6 of the lower housing 2 with a certain margin of safety. Indeed, in this central position, the EPDM seal 102 does not risk seeing its position drift on the flat junction edge 6, to the point of no longer being fully supported against said flat junction edge 6 .
- Figure 5 which relates to the second preferred embodiment of a housing 100 according to the invention, it is not necessary that the metal frame 101 extends over the entire length of the joint EPDM 102. Indeed, it was verified that the EPDM seal 102 could be handled with the same efficiency by the robots, that the metal frame 101 extends over the entire length of said EPDM seal 102, or that it does not extends only partially along this EPDM seal 102.
- the metal frame 101 does not extend over the entirety of the EPDM seal 102, it preferentially appears discontinuously along this EPDM seal 102, so that the seal formed by the EPDM seal 102 and by the metal frame 101, alternates the zones 104 with metal screen 101 and the zones 105 without metal screen 101.
- the EPDM seal 102 takes on a particular form, consisting into a main segment 106 connecting two zo nes 104 with metal screen 101, and three secondary segments 107, 108, 109 parallel, crossing the main segment 106 being perpendicular thereto.
- the main segment 106 has a width which is less than that of the EPDM gasket 102 in the areas 104 provided with a metal screen 101.
- the three secondary segments 107, 108, 109 tend to "spread" the EPDM gasket 102 over the edge of the plane junction 6 of the lower casing 2, in the zones 105 devoid of a metal screen 101, to increase the sealing capacities of the said EPDM seal 102 in the said zones 105.
- the creation of zones 105 devoid of metal screen 101 makes it possible to use a mold of smaller dimension, because the EPDM seal 102 can then be bent in said mold, at the level of these zones 105 devoid of metal screen 101.
- the use of a mold of smaller dimension makes it possible to considerably reduce the manufacturing costs of the assembly constituted by the EPDM gasket 102 and the metal screen 101 discontinuous.
