Referring to fig. 1, a battery tray case includes: the frame body 100, the box plate 600 and the sealing rubber ring 200; a screw 300 is arranged between the frame body 100 and the box plate 600, and the screw 300 penetrates through the box plate 600 and is connected with the frame body 100; the screw 300 is provided with a pressing head 350, and the pressing head 350 is matched with the frame body 100 to press the box board 600; the sealing rubber ring 200 surrounds the periphery of the pressing head 350 and seals the space between the pressing head 350 and the box plate 600, a flange abutting against the box plate 600 is arranged on the pressing head 350, and the sealing rubber ring 200 covers the flange. After the screws 300 connect the frame body 100 and the box board 600, the pressing head 350 will be exposed outside the box board 600 and cooperate with the frame body 100 to press the box board 600 relatively, so that the box board 600 and the frame body 100 are relatively fixed. The packing rubber ring 200 can seal the gap between the packing head 350 and the box plate 600, thereby improving the airtightness of the produced product. By providing the flange on the pressing head 350 and surrounding the sealant ring 200 on the flange, the contact area between the pressing head 350 and the sealant ring 200 can be increased, thereby improving the sealing effect of the sealant ring 200. In addition, the flange enables the sealing rubber ring 200 to extend along the inner and outer sides of the flange when being pressed, and further increases the contact area between the sealing rubber ring 200 and the flange and the box plate 600, so that the sealing effect of the sealing rubber ring 200 can be directly and effectively increased through a simple pressing means, and the requirement of the battery box industry for increasing the air tightness performance is met.

Specifically, the flange is a thin-walled structure and is disposed at an end of the hold-down head 350 adjacent to the box plate 600.

In some embodiments, referring to fig. 4, the frame body 100 is provided with connecting nails 700, and the box board 600 is connected to the frame body 100 through the connecting nails 700; a sealing part 800 is provided on a surface of the frame body 100 away from the box plate 600, and the sealing part 800 closes a gap between the connection nail 700 and an inner wall of the frame body 100. The connecting nail 700 can further connect the box board 600 and the frame body 100, thereby ensuring a more stable and reliable connecting effect between the two. The sealing part 800 can seal the gap between the frame body 100 and the connecting nail 700 from the inside of the frame body 100, so that the air tightness of the whole processed product is enhanced, and the requirement of the battery box industry for increasing air tightness performance can be met.

Specifically, the connection nail 700 is a rivet. Of course, the connecting pin 700 may have other structures, such as a threaded pin, a straight pin, or even a nut. The specific implementation manner can be adjusted according to actual needs, and is not limited herein.

In some embodiments, referring to fig. 2, the sealing part 800 includes a sealing glue applied between the coupling nail 700 and the inner wall of the frame body 100. The sealing glue can flow into the gap between the connecting nail 700 and the frame body 100 when the connecting nail is not dried and shaped, and can be matched with the part which does not flow in to realize the sealing between the connecting nail 700 and the frame body 100 after the connecting nail is dried and shaped. The sealing glue flowing into the gap between the connecting nail 700 and the frame body 100 can greatly increase the contact area between the sealing glue and the connecting nail 700 and the frame body 100 after drying and shaping, thereby achieving better sealing effect.

It is contemplated that the sealing portion 800 may be other members, such as an elastic sealing ring (not shown), which is clamped by the connection between the connecting pin 700 and the frame 100. The specific implementation manner may be adjusted accordingly according to actual needs, and is not limited herein.

In some embodiments, referring to fig. 3, the end of the screw 300 extending into the interior of the frame 100 is coated with a glue layer that closes the gap between the screw 300 and the interior wall of the frame 100. The glue layer can flow into the gap between the screw 300 and the frame body 100 when the glue layer is not dried and shaped, and can be matched with the part which does not flow into the glue layer to realize the sealing between the screw 300 and the frame body 100 after the glue layer is dried and shaped. The glue layer flowing into the screw 300 and the frame body 100 can greatly increase the contact area between the glue layer and the screw 300 and between the glue layer and the frame body 100 after drying and shaping, thereby achieving better sealing effect. Through the combined action of the glue layer and the sealing glue ring 200, the two ends of the screw 300 are effectively sealed, so that the air tightness of a processed product can be greatly improved, and the requirement of the battery box industry on increasingly improved air tightness performance is met.

The second aspect of the utility model provides an embodiment of a sealing tool, which is used for the battery tray box body and further comprises a gluing device 500, wherein the gluing device 500 is connected with a gluing gun head 400, and the gluing gun head 400 can surround and cover the pressing head 350. When the pressing head 350 abuts against the box plate 600, a closed cavity is formed between the gluing gun head 400 and the box plate 600, and the pressing head 350 is located in the cavity. After the glue applicator 500 begins to apply glue, the glue fills the closed chamber, thereby sealing between the hold-down head 350 and the boxboard 600 and eventually forming the stripper rubber ring 200. The pressing head part 350 is wrapped and covered in an all-around mode through the gluing gun head 400, and the effect of covering the gap between the pressing head part 350 and the box plate 600 in an all-around mode can be achieved effectively. Consequently, beat gluey rifle head 400 and can fill everywhere in the clearance between flange and the boxboard 600 completely when the encapsulating to reach more outstanding sealed effect, and then can deal with the demand that battery box trade improves to air tightness performance day by day.

In some embodiments, referring to fig. 5, the glue gun head 400 has a flared portion 450, the flared portion 450 having an inner diameter greater than an outer diameter of the hold-down head 350, the flared portion 450 being capable of covering the hold-down head 350 and abutting against the box plate 600. The flared portion 450 expands the radial dimension of the glue gun head 400, so that the glue gun head 400 can completely wrap the pressing head portion 350 and abut against the box plate 600 while wrapping the pressing head portion 350, thereby completely closing the gap between the pressing head portion 350 and the box plate 600. Therefore, when glue is poured, the glue gun head 400 can more completely coat the glue material on the gap between the pressing head part 350 and the box plate 600, so that a better sealing effect is achieved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
