[0029] like Figures 1 to 3As shown, a ruggedized structure for a tablet computer includes a computer housing 1, which includes a back panel 101 and a mid-frame 102. A groove 2 is formed on the outer wall of the mid-frame 102, and multiple through holes 3 are formed on the bottom surface of the groove 2, penetrating the mid-frame 102. It also includes a flexible sealing member 4, one end of which is fixedly connected to one end of the groove 2, and the other end of which is embedded in the groove 2, covering all the through holes 3. Furthermore, it includes a motherboard 8, on which multiple external interfaces are fixedly disposed, corresponding to the through holes 3.

[0030] Specifically, one side of the tablet's frame 102 is thickened or recessed to form a groove 2. A through-hole 3 is opened at the bottom of the groove 2, communicating with the interior of the frame 102. This through-hole 3 corresponds to the external interface of the motherboard 8, providing a reserved interface for connecting data cables or charging cables to the motherboard 8. When the motherboard 8 is not connected to a data cable, the flexible sealing element 4 can fill the entire groove 2, covering all the through-holes 3, preventing dust and water from entering the groove 2 and then seeping into the computer casing 1 through the through-holes 3, thus protecting the motherboard 8. In this embodiment, by creating a groove 2 on the frame 102, integrating the through-hole 3 for connecting the motherboard 8 to the external data cable into the groove 2, and embedding the flexible sealing element 4 to fill and seal the groove 2, good waterproof and dustproof functions are ensured at all interfaces without affecting the thickness of the tablet.

[0031] The flexible sealing element 4 includes a silicone strip 401, the sidewall of which fits against the inner wall of the groove 2. A sealing damping element is also fixedly disposed between the sidewall of the silicone strip 401 and the inner wall of the groove 2. The sealing damping element includes multiple sealing rings 402, which are fixedly disposed on the sidewall of the silicone strip 401. Specifically, one end of the silicone strip 401 is fixedly connected to the groove 2. Since the silicone strip 401 is flexible, the other end can be bent outward. When the other end is pulled out of the groove 2, the through hole 3 can be connected to the data cable for use. When the silicone strip 401 is fully embedded in the groove 2, the sealing ring 402 only abuts against the inner wall of the groove 2, effectively achieving dustproof and waterproof functions. To prevent the silicone strip 401 embedded in the groove 2 from being difficult to remove, the outer end face of the silicone strip 401 can be designed to extend beyond the outer end face of the middle frame 102. During use, the silicone strip 401 can be removed simply by gently prying its edge.

[0032] One end of the silicone strip 401 is fixedly provided with a plug-in portion 403, and the groove 2 has a plug hole 5 that mates with the plug-in portion 403. A limiting portion 4031 is fixedly provided on the plug-in portion 403, and the limiting portion 4031 is used to limit the movement by engaging with the inner sidewall of the middle frame 102. A guide surface 4032 is fixedly provided at the end of the limiting portion 4031 away from the silicone strip 401. Specifically, to prevent the silicone strip 401 from falling off when using the through hole 3, the plug-in portion 403 is provided to connect it to the middle frame 102, and the limiting portion 4031 limits its movement. At the same time, the silicone strip 401 is a consumable item. When it is damaged, the damaged silicone strip 401 can be removed and replaced with a new silicone strip 401. At this time, the guide surface 4032 facilitates the insertion of the limiting portion 4031 into the plug hole 5. The limiting portion 4031 here is also made of soft material, such as silicone. When force is applied during pulling, the limiting part 4031 can deform and be pulled out of the socket 5.

[0033] A positioning structure is also fixedly provided between the other end of the silicone strip 401 and the groove 2. The positioning structure includes a positioning post 6 and a positioning groove 7 that cooperate with each other. The positioning post 6 is fixedly disposed in the groove 2, and the positioning groove 7 is formed on the silicone strip 401. Specifically, since the silicone strip 401 is made of flexible material, when its movable end is embedded in the groove 2 during use, its end may not fit tightly against the inner wall of the groove 2. In this case, the positioning post 6 and the positioning groove 7 are connected to ensure that its movable end fits tightly against the inner wall of the groove 2.

[0034] The back panel 101 is integrally formed with the middle frame 102. Specifically, the integrally formed middle frame 102 and back panel 101 can have good waterproof and dustproof performance, while making the tablet computer have high overall strength and good drop resistance.

[0035] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
