DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative labor also belong to the scope of protection of the present disclosure.

[0020] Please refer to Figures 1 to 6 , a flat computer large frame wide slot type glue sealing structure is provided for the technical scheme, including the bottom shell 1 and the face shell 2 of the flat computer, the bottom shell 1 is provided with a wide slot type sealing ring installation groove 101 along its edge, the inner side of the bottom shell 1 along its edge is provided with a plurality of uniformly distributed screw connection through hole positions 102, the hole of the screw connection through hole position 102 and the protruding part 1021 provided to the outer side of the bottom shell 1 are provided, the inner side of the protruding part 1021 forms the sealing ring installation groove bend area 1011 connected with the sealing ring installation groove 101, the sealing ring installation groove bend area 1011 winds the hole of the screw connection through hole position 102 to the outer side. The face shell 2 is provided with a plurality of screw connection hole positions 202 corresponding to the screw connection through hole position 102 along the inner side of its edge, the face shell 2 is provided with a convex strip part 201 embedded in the sealing ring installation groove 101 along the bottom of its edge, the inner side of the convex strip part 201 corresponding to the screw connection hole position 202 forms the convex strip part bend area 2011 connected with the convex strip part 201, the convex strip part bend area 2011 winds the hole of the screw connection hole position 202 to the outer side. The sealing ring installation groove 101 is filled with glue by the glue machine along the sealing ring installation groove 101, the glue is solidified to form a waterproof sealing ring, and the convex strip part 201 is pressed on the upper surface of the waterproof sealing ring.

[0021] Please refer to Figure 3 , Figure 6, as preferably, the bottom surface of the convex strip part 201 is provided with a closed V-shaped convex crimping ring formed along the length direction thereof, the V-shaped convex crimping ring is pressed on the upper surface of the waterproof sealing ring, and is crimped on the waterproof sealing ring near the middle position in the width direction. The edge of the crimping on the waterproof sealing ring deforms the upper surface of the waterproof sealing ring to form a closed V-shaped groove, and the inside and outside of the V-shaped groove are tightly separated by the V-shaped convex crimping ring, thereby achieving a better waterproof sealing effect. After the bottom shell 1 and the face shell 2 are connected relative to the cover, the screw connection through hole position 102 and the screw connection hole position 202 are one-to-one corresponding, respectively installing the screw lock, and even if the water enters the hole wall of the screw connection through hole position 102, it will not enter the tablet computer from the waterproof sealing ring.

[0022] The convex strip part 201 and the V-shaped convex crimping ring structure of the bottom edge of the face shell 2 can realize that when the sealing ring installation groove 101 is filled with glue, the face shell 2 and the bottom shell 1 can be pressed and connected when the glue is not completely solidified. Because the bottom of the V-shaped convex crimping ring is formed with a sharp edge, when crimping to the glue which is not completely solidified, compared with the convex ring with a rectangular cross section, the glue will not be squeezed out of the edge. Reduce the waiting time for the glue to solidify, thereby improving the production and processing efficiency of the product.

[0023] Further, the outer side edge of the sealing ring installation groove 101 of the bottom shell 1 is higher than the inner side edge, that is, the outer edge of the bottom shell 1, and the outer side of the convex part 1021 of the face shell 2 is the outer edge of the face shell 2. The outer edge of the face shell 2 is connected with the outer edge of the bottom shell 1, so that when the face shell 2 and the bottom shell 1 are connected relative to the cover, the outer edge of the bottom shell 1 plays a limiting role on the inner side.

[0024] In the present scheme, the glue adopts any one of silicone rubber glue, polyurethane elastic glue and acrylate elastic glue.

[0025] The present scheme uses a glue dispenser to dispense glue around the sealing ring installation groove 101, and uses a glue dispensing method. The glue in liquid form can be easily filled into the sealing ring installation groove 101, and after the glue is solidified, a waterproof sealing ring is formed. The problem of time-consuming and laborious manual installation of the solid sealing ring around the sealing ring installation groove 101 is solved, and the problem of high cost of opening a special-shaped sealing ring production mold is solved.

[0026] Having described above several embodiments of the disclosure, any modifications and variations that fall within the scope of the described embodiments are also intended to be within the scope of the disclosure. As will be apparent to those skilled in the art, some modifications and variations to the embodiments described above can be practiced while staying within the scope and spirit of the described embodiments. The foregoing description of the described embodiments has been presented for the purposes of illustration and description. It is not intended to be exhaustive or to limit the described embodiments to the precise form disclosed. Many modifications and variations are possible in light of the above teachings. It is intended that the disclosed embodiments be limited only by the claims.
