DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

To make the objective, the technical solutions and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and the embodiments. It should be understood that the specific embodiments described herein are only for explaining but not for limiting the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts should fall within the scope of protection of the present invention.

Reference is made to FIG. 1, which is a schematic diagram of a tablet device provided by a first embodiment of the present invention. The tablet device 1 provided by this embodiment includes a case 2, a metal support plate 3, a support frame 4, a side button sensor 5, a side button control board 6, and an antenna module 7. In this embodiment, the case 2 has a top surface 21 and a bottom surface 22, where the top surface 21 is provided with a display frame 212 for fixedly arranging a display panel 9, and one side edge of the top surface is provided with a side button frame 211 for fixedly arranging the side button sensor 5. It should be noted that the top surface 21 and the bottom surface 22 of the case 2 are only used to explain the upper part/top and the lower part/bottom of the case 2, and do not limit the organizational structure and combination of the case 2. For example, the case may be integrally formed or composed of an upper top case, a lower top case, and at least a side case. The metal support plate 3 is arranged in the case 2, and a hollow part 31 is provided on one side edge of the metal support plate 3 that corresponds to the side button frame 211, such that the hollow part 31 forms a space 311 in the case 2 to place the support frame 4 and the antenna module 7. The support frame 4 is arranged in the space 311 and is, for example, a U-shaped bracket, and a plurality of clamping pieces 42 are arranged on two side edges 41 of an opening of the support frame 4 to be clamped to the side edge of the metal support plate 3, where the support frame 4 is a plastic component, such that a stable space is formed in the support frame 4 to prevent space compression or distortion caused by pressing the side button sensor 5 from affecting the antenna module 7. It should be noted that the support frame 4 may also be replaced with a support component made of another material or in another form, such that a stable space is formed to place the antenna module 7. The side button sensor 5 is arranged in the side button frame 211, and a side edge 41 of the support frame 4 that corresponds to the top surface 21 abuts against the side button sensor 5, where the side button sensor 5, the support frame 4, and the antenna module 7 are substantially overlapped with one another. The side button control board 6 is arranged on the side edge of the metal support plate 3, faces the opening of the U-shaped bracket, is coupled to the side button sensor 5 by a flexible flat cable 8 to receive a signal generated by pressing the side button sensor 5, and is coupled to a system circuit board by a flat cable for signal transmission. The antenna module 7 is arranged in the space of the support frame 4, where the antenna module 7 may be a type of three-dimensional antenna or a type of planar antenna, and may be an antenna used in various wireless communication technologies such as a wireless wide area network (WWAN) and a wireless local area network (WIFI). In addition, the antenna module 7 is configured to transmit and receive the signal, and the signal can be coupled to the antenna module by a flat cable to be provided to the antenna module for signal processing.

Reference is made to FIG. 2, which is a schematic diagram of a tablet device provided by a second embodiment of the present invention. It can be noted that the tablet device 10 provided by the second embodiment is roughly the same as the tablet device 1 provided by the first embodiment, and there is only the difference between the two embodiments that the support frame 4 is a sheet-like bracket and is configured to be clamped to the one side edge of the metal support plate 3 that corresponds to the hollow part 31, such that a stable space is formed below the support frame 4 to prevent space compression or distortion caused by pressing the side button sensor 5 from affecting the antenna module 7.

Reference is made to FIG. 3, which is a schematic diagram of a tablet device provided by a third embodiment of the present invention. It can be noted that the tablet device 100 provided by the third embodiment is roughly the same as the tablet device 1 provided by the first embodiment, and there is only the difference between the two embodiments that the support frame 4 is an L-shaped bracket, and a plurality of clamping pieces 42 are arranged on the two side edges 41 of the support frame 4 to be clamped to the side edge of the metal support plate 3 and the bottom surface 22, such that a stable space is formed below the support frame 4 to prevent space compression or distortion caused by pressing the side button sensor 5 from affecting the antenna module 7.

Reference is made to FIG. 4, which is a schematic diagram of an antenna module provided by an embodiment of the present invention. The antenna module 7 provided by this embodiment is fixed in the space 311 by means of locking or by other means of bonding, buckling, etc. The present invention is not limited to the means of fixing in the space 311.
