[0028] In order for those skilled in the art to better understand the utility model, the utility model technical scheme is further explained below in combination with the drawings and examples.
[0029] As Figures 1-6 Indicated, a PACK box structure with waterproof effect, including two first inner sealing plates 1 and two second inner sealing plates 2 that are oppositely arranged, four right angle plates 3 with right angle cross section are arranged on the edge outside of the first inner sealing plate 1 and the second inner sealing plate 2, the rubber strip 4 is sealingly connected to the outside of the first inner sealing plate 1 and the second inner sealing plate 2 on the inner side of the two side edges of the four right angle plates 3, the rubber strip 4 is located on the edge of the first inner sealing plate 1 or the second inner sealing plate 2, by setting the rubber strip 4, waterproof effect can be achieved, at the same time, when the box outside is impacted, since the rubber strip 4 is an elastic material, part of the impact can be resisted, the right angle plate 3 is screw-connected with the screw 5 between the first inner sealing plate 1 and the second inner sealing plate 2, the screw 5 is located on the outside of the rubber strip 4, the upper side and the lower side of the box are sealingly connected with the sealing cover 6.
[0030] The technical scheme of the embodiment is adopted, the right angle plate 3 is located at the four corners of the rectangle, the side edge of the right angle plate 3 is connected with the first sealing plate 1 and the second sealing plate 2, the screw 5 is used to fix the right angle plate 3 with the first sealing plate 1 and the second sealing plate 2, at the same time, the rubber strip 4 is tightly pressed against the first sealing plate 1 and the second sealing plate 2, waterproof effect is achieved, the upper side and the lower side of the box are sealed by the sealing cover 6, the battery is located inside the first inner sealing plate 1 and the second inner sealing plate 2, so that the entire box has waterproof effect, the connection is not welded, and the box is more convenient to disassemble and recycle.
[0031] Refer to Figure 2The upper end and the lower end of the rubber strip 4 are located in the right-angled plate 3 and the first inner sealing plate 1 and the second inner sealing plate 2, and the lower side of the sealing cover 6 is provided with a sealing ring 61 embedded between the right-angled plate 3, the first inner sealing plate 1 and the second inner sealing plate 2. In the embodiment, the sealing ring 61 is located outside the first sealing plate 1 and the second sealing plate 2, and seals the upper side and the lower side of the box body, the sealing ring 61 is clamped between the right-angled plate 3, the first sealing plate 1 and the second sealing plate 2, and the lower side of the sealing ring 61 is sealingly connected with the end of the rubber strip.
[0032] Referring to Figures 1-2 The sealing cover 6 is connected with the upper side and the lower side of the first inner sealing plate 1 and the second inner sealing plate 2 through the fixing piece 7. In the embodiment, the sealing cover 6, the first sealing plate 1 and the second sealing plate 2 are fixedly connected through the fixing piece 7.
[0033] Referring to Figure 3 The outer side of the first inner sealing plate 1 and the second inner sealing plate 2 is provided with the explosion-proof plate 8, and the two sides of the explosion-proof plate 8 are fixedly connected with the positioning column 81 penetrating through the right-angled plate 3, and the side edge of the right-angled plate 3 is provided with the positioning groove of the positioning column 81. In the embodiment, the explosion-proof plate 8 is arranged to further protect the box body and reduce the explosion range of the box body.
[0034] Referring to Figure 3 The spring 82 is arranged between the explosion-proof plate 8 and the right-angled plate 3 and is sleeved with the positioning column 81. In the embodiment, the spring 82 is arranged, so that the explosion-proof plate 8 can compress the spring 82 and move outward.
[0035] Referring to Figure 2 And 6 Two notches are arranged on the side edge of the right-angled plate 3 on the side close to the middle of the box body. In the embodiment, the two notches are used to form a rib on one side of the positioning column 81, so as to change the rib strength of the right-angled plate 3. The narrower the width of the rib, the lower the strength.
[0036] Referring to Figure 6 The arrangement of the two notches makes the width of the rib on one side of the positioning column 81 gradually widen. In the embodiment, the plate material on one side of the positioning column 81 is gradually widened, so that when the battery explodes, the box body has a tendency to expand, and the positioning column 81 on the two sides of the explosion-proof plate 8 has a tendency to move to the middle of the box body. When the positioning column 81 moves to the middle, the positioning column 81 first damages the rib of the right-angled plate 3, and then continues to damage the next rib. In the process of damage, the width of the rib gradually increases, so the force required to damage the rib gradually increases, thereby effectively controlling the explosion range.
