Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present application, unless expressly stated or limited otherwise, the terms "connected," "connected," and "fixed" are to be construed broadly, e.g., as meaning permanently connected, removably connected, or integral to one another; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

In this application, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact of the first and second features, or may comprise contact of the first and second features not directly but through another feature in between. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

In the description of the present embodiment, the terms "upper", "lower", "right", etc. are used in an orientation or positional relationship based on that shown in the drawings only for convenience of description and simplicity of operation, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present application. Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

As shown in fig. 1 and 2, a sealing structure for an electronic device includes a front shell 1 and a bottom shell 2, wherein the front shell 1 includes a panel and a first sealing surface 11, the bottom shell 2 includes a bottom plate and a second sealing surface 21, the first sealing surface 11 and the second sealing surface 21 are fixedly connected to form a side wall of the electronic device, the first sealing surface 11 includes a first vertical surface 11a and a first transition surface 11b, the first vertical surface 11a is disposed between the panel and the first transition surface 11b and is perpendicular to the panel, and the other end of the first transition surface 11b extends towards the inside of the shell; the second sealing surface 21 comprises a second vertical surface 21a and a second transition surface 21b, the second transition surface 21b is arranged between the second vertical surface 21a and the bottom plate, the second vertical surface 21a is arranged in parallel with the first vertical surface 11a, the second transition surface 21b is arranged in a position and shape corresponding to the first transition surface 11b, a gap 4 is formed between the first transition surface 11b and the second transition surface 21b, sealing foam 3 with a closed shape is arranged in the gap 4, and when the first sealing surface 11 and the second sealing surface 21 are fixedly connected, the sealing foam 3 is compressed and fills the gap 4 to realize sealing.

The sealing foam 3 can only be arranged on the transition surface and cannot be attached to the vertical surface, because the sealing foam 3 needs to be compressed by the cooperation of the surface shell 1 and the bottom shell 2, the formed compression state needs to be maintained, the vertical surface is basically in the vertical direction, the compression pressure of the sealing foam 3 cannot be provided, and the compression state of the foam cannot be formed and maintained. As shown in fig. 2 and 3, the transition surface may be an inclined surface or an arc surface, that is, the first transition surface 11b and the second transition surface 21b are correspondingly configured as an inclined surface or an arc surface. And when the transition surface is set to be the cambered surface, the effect of the gentle large cambered surface is better, and poor sealing can be effectively prevented.

As shown in fig. 2 and 3, the width of the gap 4 between the first transition surface 11b and the second transition surface 21b may be designed as required, and as shown in fig. 1, the widths of the gap 4 between the first transition surface 11b and the transition surfaces are preferably set to be equal. The width of the gap 4 can be any value of 0.1-0.3 mm. If the electronic product is a mobile phone or a tablet computer, the width of the gap 4 is preferably set to 0.2 mm.

In addition, in order to ensure the sealing reliability, the sealing foam 3 should have a sufficient compression area, and the width L of the first transition surface 11b and the second transition surface 21b should preferably not be less than 1mm, as shown in fig. 2 and 3, and the width L of the second transition surface 21b is equal to the width L of the first transition surface 11b, so that the compression effect of the sealing foam 3 is better.

As shown in fig. 4 and 5, in order to prevent the sealing foam 3 from moving during the compression process, a limiting rib 5 for limiting the sealing foam 3 is arranged on the first transition surface 11b, and the limiting rib 5 refers to a protrusion arranged on the first transition surface 11b or the second transition surface 21b, wherein in some embodiments of the present application, the width and the height of the limiting rib 5 are consistent and continuous, which can make the production process of the limiting rib 5 simpler. The limiting bone 5 is arranged on the inner side or the outer side of the sealing foam 3, and the shape of the limiting bone 5 is matched with that of the foam. Fig. 1 shows the situation in which the stopper bone 5 is arranged on the inner side of the sealing foam 3, and a space of 0.2mm is left between the sealing foam 3 and the stopper bone 5, so that the sealing foam 3 has a sufficient accommodation space when compressed.

The fixed connection is one or more of clamping, buckling and bolt connection. As shown in fig. 6, a bayonet 6 is arranged on the first vertical surface 11a, a convex buckle matched with the bayonet 6 is arranged on the second vertical surface 21a, and after the buckle is clamped in the bayonet 6, the surface shell 1 and the bottom shell 2 are combined together. In order to make the connection more effective, the panel and the bottom plate are also provided with bolt holes 7 for mounting bolts.
