The present embodiment provides a vehicle including a battery pack including a double-layer seal case.

As shown in fig. 1 to 4, the double-layer sealed box of the present embodiment includes a box body 1, a box cover 4 and a sealing strip 5, wherein a boss 2 is disposed on an opening end surface of the box body 1, and a sealant 3 is disposed on a top of the boss 2; the box cover 4 is covered on the opening end face of the box body 1, the bottom face of the box cover 4 is pressed against the top of the boss 2, the sealant 3 is used for bonding and fixing the box cover 4 and the box body 1, and a containing groove is defined by the box body 1, the boss 2 and the box cover 4; the sealing strip 5 is arranged in the accommodating groove in a sealing mode.

In the assembled state of the box cover 4 and the box body 1 shown in fig. 3 and 4, the bottom surface of the box cover 4 is not in contact with the sealant 3, when the box cover 4 and the box body 1 are completely sealed, the sealing strip 5 and the sealant 3 are compressed, and the bottom surface of the box cover 4 abuts against the top of the boss 2.

Specifically, the battery pack of the embodiment is a non-detachable battery pack, the box body 1 and the box cover 4 are not detachable after being hermetically mounted, the box cover 4 and the box body 1 are permanently bonded and fixed by the sealant 3 in the embodiment, fasteners such as bolts or screws are not required to fixedly connect the box cover 4 and the box body 1, a locking and fixing structure is omitted, threaded connecting holes do not need to be formed in the box cover 4 and the box body 1, galvanic corrosion is avoided, particularly in a salt spray environment, the locking and fixing structure can cause severe galvanic corrosion, the embodiment is further provided with the sealing strip 5, the sealing strip 5 and the sealant 3 form double-layer sealing, the sealing effect is improved, the battery pack can meet the sealing requirement within the service life, the dispensing amount of the sealant 3 can be properly reduced due to the fact that the sealant 3 is dispensed on the boss 2, the material cost is reduced, the boss 2 can limit displacement of the sealing strip 5 on the horizontal plane, the sealing strip 5 can be stably sealed and arranged in a containing groove formed by enclosing the box body 1, the boss 2 and the box cover 4, and the sealing effect is further guaranteed. And compare with the simple sealing strip 5 of only adopting box 1 with case lid 4 is sealed, this embodiment adopts sealing strip 5, boss 2 and sealed 3 cooperations of gluing to use for the use amount of sealing strip 5 reduces half, practices thrift the material cost.

In this embodiment, sealing strip 5 sets up in the peripheral part of boss 2, and sealed 3 of protection is not influenced by the environment, reduces ageing speed, especially in some salt fog environment and moisture environment, and sealing strip 5 can be sealed 3 isolated with sealed glue with the air, and sealed glue 3 is when not influenced by salt fog environment and moisture environment, and adhesion performance and life all obtain effectively improving.

In other embodiments, if the application environment of the battery pack excludes a salt fog environment and a moisture environment, the boss 2 is disposed on the outer periphery of the sealing strip 5, so as to ensure a better sealing effect.

Optionally, the side of the boss 2 departing from the sealing strip 5 is flush with the inner wall of the box body 1 located on the same side, so that the double-layer sealing box is guaranteed to have a smooth inner wall.

Optionally, the sealing strip 5 is made of compressible silicone foam.

Optionally, the outer side surface of the box cover 4, the outer side surface of the sealing strip 5 and the outer side surface of the box body 1 are flush.

Optionally, the sealant 3 is dispensed in the middle of the top of the boss 2, so that when the bottom surface of the box cover 4 abuts against the sealant 3, the sealant 3 can uniformly flow to two sides.

Optionally, the boss 2 encloses a circle at the opening end face of the box body 1, and the sealant 3 encloses a circle at the top of the boss 2.

In the present embodiment, the case 1 is integrally formed with the boss 2.

When the double-layer sealing box is assembled and produced, firstly, glue 3 is dispensed at the middle position of the top of the boss 2, the sealing strip 5 is installed on the opening end face of the box body 1, then the box cover 4 is installed on the opening end face of the box body 1, the bottom face of the box cover 4 is firstly contacted with the sealing strip 5, the box cover 4 is continuously pressed down to be close to the box body 1, the sealing strip 5 is compressed until the bottom face of the box cover 4 is contacted with the top of the boss 2, the sealing strip 3 positioned at the top of the boss 2 diffuses towards the periphery of the boss 2, the box cover 4 is pressed by the pressure maintaining tool until the box cover 4 is adhered to the box body 1 by the sealing strip 3, in the embodiment, the box cover 4 is pressed on the box body 1 by the pressure maintaining tool, the sealing strip 5 is compressed, particularly, the sealing strip 5 is made of compressible silica gel foam, when the sealing strip is compressed by external force, the elastic potential energy of the sealing strip 5 is not enough to overcome the original shape of the sealing strip 5, after the preset pressure maintaining time, the box cover 4 is completely adhered and fixed with the box body 1 by the sealing strip 3, the sealing strip 5 can not be separated from the box body 1, and the box cover 4, the box body 1 can be prevented from being lifted up after the box cover 4.

In addition, the foregoing is only a preferred embodiment of the present invention and the technical principles applied thereto. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
