For the purpose of illustrating the technical content, constructional features, objects and effects achieved by the present invention in detail, reference is made to the following detailed description taken in conjunction with the accompanying drawings.
Referring to fig. 1 and 2, the present invention discloses a waterproof structure of a battery module 100, wherein the battery module 100 includes at least one battery pack 1 and a housing 2.
At least one battery pack 1 is mounted in the case 2.
Referring to fig. 2 to 4, one side of the housing 2 is defined as an opening 21, and an opening 22 is formed in the middle of the opening 21. The periphery of the opening 22 has a limiting portion 211 protruding outward and surrounding the opening 22. The opening surface 21 further has a first waterproof layer 3 sleeved on the position-limiting portion 211.
The opening surface 21 has a plurality of fixing grooves 212 formed by depressions. The first waterproof layer 3 is provided with a plurality of first fixing holes 31. The first fixing hole 31 is formed corresponding to the fixing groove 212. The periphery of each first fixing hole 31 has a first filling portion 311 formed to protrude outward. The first waterproof layer 3 further has a plurality of positioning blocks 32 protruding outwards.
The open face 21 is also covered with an outer lid 4. The outer cover 4 is provided with a second waterproof layer 5, a plurality of gaskets 6 and a plurality of fasteners 7. The cover 4 has a plurality of second fixing holes 41, and the second fixing holes 41 are disposed corresponding to the fixing slots 212. The periphery of the outer lid 4 has an extending portion 42 formed to protrude inward, and the extending portion 42 further protrudes toward the middle to form a contact portion 43. The contact portion 43 is attached to the first waterproof layer 3, and the contact portion 43 is formed with a plurality of third fixing holes 431, and the third fixing holes 431 are formed corresponding to the fixing grooves 212. The first filling part 311 protrudes into the fixing groove 212. The outer surface of the contact portion 43 has a plurality of positioning grooves 432 formed by depressions, and the positioning grooves 432 are disposed corresponding to the positioning blocks 32 of the first waterproof layer 3. The second waterproof layer 5 is disposed in the cover 4 and clamped by the inner wall of the cover 4 and the position-limiting portion 211 of the housing 2, so that the second waterproof layer 5 seals the gap between the inner wall of the cover 4 and the position-limiting portion 211 of the housing 2. The second waterproof layer 5 is formed with a plurality of fourth fixing holes 51. The fourth fixing hole 51 is formed corresponding to the fixing groove 212.
