As shown in fig. 1 to 4, the moistureproof battery box in the present embodiment includes a box body 10 and a box cover 20 that are movably connected, a mounting gap is formed between the box cover 20 and the box body 10, and an elastic sealing block 30 is provided in the mounting gap; the elastic sealing block 30 comprises a first sealing surface 31, and the first sealing surface 31 is attached to the box body 10; the resilient sealing block 30 further comprises a first sealing end 321 and a second sealing end 322; the first sealing end 321 is in surface contact with the case cover 20 in the vertical direction, and the second sealing end 322 is in line contact with the case cover 20 in the horizontal direction; that is, the contact area between the first sealing end 321 and the case cover 20 is a first area, the contact area between the second sealing end 322 is a second area, the first area is far greater than the second area, the contact surface between the first sealing end 321 and the case cover 20 is planar, and the contact surface between the second sealing end 322 and the case cover 20 is linear; since the elastic sealing block 30 is made of elastic material, the friction force is positively correlated with the contact area, and the second area is smaller, which corresponds to the friction force in the vertical direction, so as to avoid affecting the movement of the case cover 20.
Specifically, the moisture-proof battery box is provided with an elastic sealing block 30 between the box body 10 and the box cover 20, the elastic sealing block 30 is in surface contact with the box cover 20 in the vertical direction by a first sealing end 321 thereof, and is in line contact with the box cover 20 in the horizontal direction by a second sealing end 322 thereof, thereby sealing an installation gap between the box cover 20 and the box body 10 to prevent moisture in the box body 10; meanwhile, when the case cover 20 needs to be opened, the case cover 20 is moved along the vertical direction, and at the moment, only the second sealing end 322 in line contact with the case cover 20 along the horizontal direction acts on the case cover 20 through the friction force in the vertical direction, but the second sealing end 322 is in line contact, so that the contact area is smaller, and for the elastic sealing block 30 with elasticity, the friction force generated along the vertical direction is smaller, thereby facilitating the movement of the case cover 20 relative to the case body 10 and facilitating the replacement of the battery cells in the case body 10; therefore, the dampproof battery box has the advantages of high sealing performance and convenience in replacement of the battery core.
In this embodiment, as shown in fig. 1 to 4, a mounting groove 11 is formed in a box 10 in this embodiment, a positioning portion 12 is protruding outwards from a notch of the mounting groove 11 in the box 10, and the positioning portion 12 is disposed around the notch of the mounting groove 11; the case cover 20 is provided with a positioning groove 21, and the case cover 20 is movably sleeved outside the positioning part 12 through the positioning groove 21. The first sealing surface 31 is attached to a wall surface of the positioning portion 12 away from the mounting groove 11, the first sealing end 321 is in contact with a groove bottom wall of the positioning groove 21, and the second sealing end 322 is in contact with a groove side wall of the positioning groove 21.
Further, the wall surface of the positioning portion 12 away from the mounting groove 11 includes a positioning inclined surface 121, and the positioning inclined surface 121 is disposed obliquely with respect to the vertical direction; the first sealing surface 31 is attached to the positioning inclined surface 121, wherein the elastic sealing block 30 can be coated on the first sealing surface 31 and the positioning inclined surface 121 by glue to connect the positioning portion 12 and the elastic sealing block 30. Wherein, setting up the location inclined plane 121 is convenient for the staff to paste the elastic sealing piece 30 on the location portion 12 fast.
Further, the cross-sectional profile of the elastic sealing block 30 is rectangular; the first sealing end 321 is a corner of the elastic sealing block 30, and the second sealing end 322 is another corner of the elastic sealing block 30. It will be appreciated that the elastic sealing block 30 includes four corners, two of the four corners are located on the first sealing surface 31, and two corners are attached to the positioning inclined surface 121, and since the positioning inclined surface 121 is disposed obliquely with respect to the vertical direction, it can be seen with reference to fig. 3 and 4, and the corner at the lower left corner is the furthest component of the positioning portion 12, so that when the case cover 20 is sleeved outside the positioning portion 12 through the positioning groove 21, the corner at the lower left corner abuts against the groove sidewall of the positioning groove 21, and the first sealing effect is achieved.
It should be added that, when the case cover 20 is sleeved outside the positioning portion 12 through the positioning groove 21, the first sealing end 321 is deformed under pressure, so that the contact area between the first sealing end 321 and the groove bottom wall of the positioning groove 21 is increased, which is equivalent to increasing the friction force in the horizontal direction, so that the connection of the case cover 20 on the horizontal plane relative to the case body 10 is more stable.
As another alternative embodiment, as shown in fig. 3, a first sealing hole 22 is formed in the bottom wall of the positioning groove 21 at a position corresponding to the first sealing end 321 in the vertical direction, where the first sealing hole 22 corresponds to a sealing channel.
As another alternative embodiment, as shown in fig. 4, the case cover 20 is provided with a second sealing hole 23 in a horizontal direction, and the second sealing hole 23 communicates with the first sealing hole 22; the opening of the second sealing hole 23 is connected with a sealing glue nail 24 in a sealing way. Namely, a first sealing hole 22 is formed in the bottom wall of the positioning groove 21, and then a second sealing hole 23 is formed from the end face of the case cover 20, so that the second sealing hole 23 is communicated with the first sealing hole 22, and the second sealing hole 23 is sealed by a sealing glue nail 24, so that the volume of a sealing channel is increased. The inlet of the sealing channel is arranged corresponding to the first sealing end 321, so that even if water vapor enters the installation gap, the water vapor can be guided through the sealing channel, and the water vapor is prevented from entering the box 10.
In the present embodiment, the cover 20 is rotatably connected to the case 10 by a hinge, so that the cover 20 can rotate relative to the case 10; the cover 20 is rotatable in a direction approaching the notch of the mounting groove 11 so that the positioning groove 21 of the cover 20 is fitted over the positioning portion 12.
In summary, the dampproof battery box provided by the embodiment has the advantages of high sealing performance and convenience in battery core replacement.
