[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention, wherein the same components are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0020] Reference Figure 1-6 As shown, a prepaid keyboard watch with GPRS includes a watch case 1, a GPRS communication module 2 arranged in the watch case 1, and a battery module 3 that can be electrically connected to the GPRS communication module 2. The GPRS communication module 2 and the battery module 3 are both separately arranged from the watch case 1. A mounting groove 11 for embedding the GPRS communication module 2 and the battery module 3 is provided on the watch case 1. A cover plate 12 is provided at the opening of the mounting groove 11. When the cover plate 12 is buckled on the opening of the mounting groove 11, the GPRS communication module 2 and the battery module 3 can be encapsulated in the mounting groove 11. Two connection sockets that can be coupled to the GPRS communication module 2 and the battery module 3 respectively are provided in the mounting groove 11. The GPRS communication module 2 and the battery module 3 are both provided with a connection plug 4 that can be plugged into the connection socket. The GPRS communication module 2 and the battery module 3 can be detachably connected to the watch case 1 through the detachably connected connection plug 4 and the connection socket respectively.
[0021] In the present application, the GPRS communication module 2 and the battery module 3 are independent of each other, and can be disassembled and assembled through the connecting plug 4 and the connecting socket and the keyboard table respectively, so that when the GPRS communication module 2 is damaged or when the battery module 3 needs to be replaced, it is convenient to only remove the cover plate 12, and then the damaged GPRS communication module 2 or battery module 3 can be removed, and the new module can be inserted to complete the replacement, making the replacement more convenient and effectively improving the disassembly and assembly efficiency.
[0022] A positioning plug block 21 is protruded on the outer wall of the GPRS communication module 2 facing the cover plate 12, and a positioning hole 121 for inserting the positioning plug block 21 is provided on the cover plate 12. The positioning hole 121 is set through the wall thickness of the cover plate 12. Figure 1 As shown, the cover plate 12 can be detachably fixed to the watch case 1 by screws, which facilitates the requirements of detachable and firmly fixed cover plate 12. At the same time, the cover plate 12 and the GPRS communication module 2 can further improve the placement stability of the GPRS communication module 2 through the plug-in positioning block 21 and the positioning hole 121, effectively improving the coupling stability of the GPRS communication module 2 and the shell, and improving the stability of the keyboard watch.
[0023] In addition, refer to Figure 5 As shown, the positioning plug 21 can be made of a transparent light-conducting material, wherein a lamp bead 25 capable of displaying the operating status of the GPRS communication module 2 is arranged at the corresponding position of the positioning plug 21 in the GPRS communication module 2, so that the operating status of the GPRS communication module 2 can be directly indicated on the case 1 through the color and flashing of the lamp bead 25, which greatly improves the flexibility of using the keyboard watch.
[0024] A limiting protrusion for limiting the position of the GPRS communication module 2 is convexly arranged in the installation groove 11, and a limiting groove 22 for the limiting protrusion to be embedded is provided on the outer wall of the GPRS communication module 2. When the limiting protrusion slides into the limiting groove 22, the connecting plug 4 can be accurately inserted into the connecting socket. The connection and cooperation between the limiting protrusion and the limiting groove 22 can not only facilitate the positioning and installation of the GPRS communication module 2, and have a foolproof effect, but also can further improve the placement stability of the GPRS communication module 2, and the plugging accuracy and stability of the connecting plug 4 and the connecting socket.
[0025] The GPRS communication module 2 is provided with a slot 23 for installing a SIM card, and an openable flip cover 24 is provided at a position corresponding to the slot 23 on the GPRS communication module 2. Figure 5 As shown, the insertion slot 23 is a well-known technology and adopts a conventional design to facilitate the installation of the SIM card, and the setting of the flip cover 24 can further prevent the SIM card from falling, and also has the function of dust prevention.
[0026] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
