- the sealing material 52A is sandwiched between the outer side surface 36b of the square frame portion 36 and the inner wall 14a of the casing main body 14. As shown in FIG.
- the lip portions 70, 72, 74 are in sliding contact with the inner wall 14a of the casing main body 14.
- the outer peripheral surface 54b of the base 54 keeps a predetermined distance from the inner wall 14a of the casing main body 14. As shown in FIG. Therefore, the application of an excessive load to the base portion 54 due to the sliding contact can be avoided. Rotation of the base 54 is thus avoided. In addition, it is possible to prevent the base portion 54 from being turned up (twisted). Since the thickness of the lips 70, 72, 74 along the axial direction of the battery pack 10 (the insertion direction of the top cover 16) is sufficiently small, the frictional force between the lips 70, 72, 74 and the casing body 14 is small. . Therefore, the top cover 16 with the sealing material 52A attached can be easily inserted into the upper opening 22. As shown in FIG. For this reason, the work of attaching the top cover 16 to the casing main body 14 is facilitated.
- the sealing member 52A has a protruding end 78 protruding toward the casing body 14 from the base 54.
- a load acts on the seal member 52A from the insertion start side toward the insertion end point side. It is assumed that this load causes the sealing member 52A to expand or move along the axial direction of the battery pack 10 .
- the head 76 is blocked by the head receiving portion 40 .
- the load acting on the projecting end portion 78 is transmitted to the head receiving portion 40 via the head portion 76 . That is, the head 76 reliably contacts the head receiving portion 40 . Therefore, the sealing material 52A is prevented from stretching or moving to the extent that it gets over the head receiving portion 40 .
- the leg portion 56 of the seal member 52A extends toward the lower end surface 36a of the square frame portion 36 of the top cover 16. As shown in FIG. That is, the inner edge of the leg 56 covers the lower end surface 36a. Therefore, it is difficult for the leg portion 56 to separate from the rectangular frame portion 36 . Based on this and the fact that the head 76 is in contact with the head receiving portion 40 as described above, the seal member 52A is firmly positioned. As a result, when the top cover 16 is inserted into the upper opening 22, even if the lips 70, 72, and 74 slide against the inner wall 14a of the casing body 14, the load prevents the seal member 52A from being displaced. be done. For the above reasons, the operation of assembling the top cover 16 to the casing main body 14 is facilitated. In other words, workability is improved.
- the lower end surface of the foot portion 56 which is the insertion start side end surface of the sealing material 52A, contacts the annular stopper wall 24. As shown in FIG. This completes the insertion of the top cover 16 into the upper opening 22 . At this point, lips 70 , 72 , 74 are collapsed toward base 54 .
- the top cover 16 is attached to the casing body 14 with bolts (not shown). As the bolts are tightened, mainly the leg portion 56 , the base portion 54 and the head portion 76 are crushed along the axial direction of the battery pack 10 .
- the battery pack 10 is housed, for example, in a battery housing of an external load such as an electric vehicle or a generator, and supplies electric power to the external load.
- an external load such as an electric vehicle or a generator
- electric vehicles are operated outdoors. During this drive, it may rain.
- a seal is provided between the battery housing portion and the lid portion that closes the battery housing portion.
- the sealing performance is degraded due to aging of the sealing material, rainwater or muddy water splashed up during operation may enter the battery housing. In this case, there is a concern that the battery pack 10 (particularly the top cover 16) may be exposed to water.
- the sealing structure 50 is formed by sandwiching the sealing material 52A having the above shape between the top cover 16 and the casing main body 14 .
- the seal member 52A prevents the base portion 54 from rotating.
- the base portion 54 is turned over.
- sealing performance is ensured, so rainwater, muddy water, etc. is prevented from entering between the top cover 16 and the casing main body 14 .
- excellent sealing performance can be obtained.
- the lip portions 70 and 74 may be deformed.
- three lips 70, 72, 74 are provided. Even if the lips 70, 74 are deformed as described above, the lip 72 retains its original shape. Therefore, the sealing performance is ensured by the lip portion 72 . Therefore, it is possible to prevent liquid such as rain water or muddy water from entering the casing 18 in the same manner as described above. The same is true when four or more lip portions are provided.
- the outer side surface 36b of the square frame portion 36 has a substantially linear shape extending along the axial direction of the battery pack 10. As shown in FIG. However, as shown in FIG. 5, the outer side surface 36b of the square frame portion 36 may be inclined so as to approach the casing main body 14 from the insertion start side toward the insertion end point side.
- Top cover 16 is generally made of resin. By forming the outer side surface 36b into such a shape, it becomes easy to separate from the mold after molding. That is, in this case, a so-called draft angle 80 is formed on the outer surface 36b.
- the base portion 54 of the sealing material 52B it is preferable to incline the base portion 54 of the sealing material 52B along the outer surface 36b.
- the amount of protrusion of the lip portion 70 on the insertion start side where the base portion 54 is most distant from the casing main body 14 is maximized.
- the protrusion amount of the lip portion 74 on the side of the insertion end point where the base portion 54 comes closest to the casing main body 14 is minimized.
- the amount of protrusion of the lip portions 70 , 72 , 74 is determined so that each tip of the lip portions 70 , 72 , 74 abuts the inner wall 14 a of the casing main body 14 .
- the base portion 54 of the sealing material 52C may be linear along the direction in which the top cover 16 is inserted into the casing main body 14.
- the base portion 54 has a linear shape extending along the inner wall 14 a of the casing body 14 . In this case, the amount of projection of the protrusion 60 on the insertion start side is maximized, and the amount of protrusion of the protrusion 64 on the insertion end point side is minimized.
- the inner wall 14a of the casing body 14 is inclined. Specifically, the inner wall 14a approaches the square frame portion 36 of the top cover 16 as it goes from the insertion start side (upper opening 22) of the casing main body 14 into the top cover 16 toward the insertion end point side (annular stopper wall 24). tilt to
- the sealing material 52D When the sealing material 52D is attached to the square frame portion 36, it is not particularly necessary to incline the base portion 54 of the sealing material 52D. That is, the base portion 54 of the sealing material 52D can be formed in a linear shape along the outer side surface 36b of the rectangular frame portion 36.
- the lip portion 70 on the insertion start side comes closest to the casing main body 14 .
- the lip portion 74 on the insertion end point side is the farthest away from the casing body 14 . Therefore, the amount of protrusion of the lip portion 70 is minimized, and the amount of protrusion of the lip portion 74 is maximized.
- the amount of protrusion of the lip portions 70 , 72 , 74 is determined so that the tips of the lip portions 70 , 72 , 74 abut against the inner wall 14 a of the casing body 14 .
- Draft angles 80 and 82 may be provided on both the outer surface 36b of the square frame portion 36 and the inner wall 14a of the casing main body 14. In this case, the projection amounts of the projections 60, 62, 64 and the projection amounts of the lip portions 70, 72, 74 are appropriately determined.
