[0017] The detailed description and technical contents of the present invention are described as follows with reference to the accompanying drawings. However, the accompanying drawings are only provided for reference and description and are not intended to limit the present invention.

[0018] like Figure 1 and Figure 2 As shown, the present invention provides a mobile electronic device, including: a main frame 1, a back cover 3, an expansion box 4, a card reader module 5 and a battery module 6, and specifically also includes a touch panel 2. The expansion box 4, the card reader module 5 and the battery module 6 are used to be combined into an expansion component (without component symbols), and the expansion component can have the effect of expanding the use of the card reader module 5 and the battery module 6 at the same time.

[0019] The main frame 1 has two frame surfaces 11 and 12 facing each other, and a motherboard not shown in the figure is disposed in the main frame 1. The aforementioned touch panel 2 is stacked and fixed on one of the frame surfaces 11, but in other embodiments not shown in the figure, a display screen or other electronic products can also be fixed on this frame surface 11, and the present invention is not limited to this.

[0020] The back cover 3 is stacked and fixed on the other frame surface 12, so that the back cover 3 covers the main frame 1. The back cover 3 is provided with an expansion window 31 and has an outer cover surface 32 exposed outward. The expansion window 31 is connected to the main frame 1, specifically connected to the aforementioned motherboard.

[0021] The expansion box 4 is arranged corresponding to the expansion window 31 and fixed on the outer cover surface 32 of the back cover 3, so that the expansion box 4 covers and closes the expansion window 31. Figures 3 to 8 As shown, the expansion box 4 may be provided with an expansion cavity 4a (see Figure 8 ), a power cavity 4b (see Figure 8 ) and a connecting port 4311 (see Figure 5 As for the expansion box 4, it has a connection port 421 (see Figure 2 , 3 ) and an operating port 411 (see Figure 8 , 10 ), the connection port 421 is as Figure 2 An expansion window 31 is shown connected.

[0022] The card reader module 5 is disposed in the expansion cavity 4a. Preferably, the card reader module 5 is disposed and fixed on the outer side 4312 of the cover body; the battery module 6 is disposed in the power cavity 4b, so that the expansion box 4, the card reader module 5 and the battery module 6 are combined to form the aforementioned expansion assembly. The card reader module 5 is connected to the aforementioned main board through a signal wire (not shown) through the connecting port 4311 and the wiring port 421; the battery module 6 is connected to the main board through a power wire (not shown) through the wiring port 421. In other words, the signal wire and the power wire are both electrically connected to the main board through the wiring port 421.

[0023] Thus, since the card reader module 5 and the battery module 6 are electrically connected to the motherboard at the same time, the mobile electronic device of the present invention can be used for multi-functional expansion, including using the battery module 6 to extend the power supply time and using the card reader module 5 to use various readable and writable cards (such as smart cards), especially the battery module 6 and the card reader module 5 can be used for expansion at the same time. In addition, the combined expansion component can also be used alone, for example, used alone as a mobile power supply (when the power module 6 is activated) or used alone as a card reader (when the card reader module 5 is activated).

[0024] The expansion box 4 forms the aforementioned expansion chamber 4a (see Figure 8 ), power cavity 4b, communication port 4311 and wiring port 421, the present invention is not limited, in this embodiment, the expansion box 4 includes a first shell 41, a second shell 42 and a cover 43 as an example for explanation. The first shell 41 and the second shell 42 are combined to form a shell, and a box space 40 (reference Figure 4The cover 43 covers the inner space 40 of the box and is fixed to the second shell 42, so as to form the aforementioned power cavity 4b between the inner side of the cover (no element symbol is marked) and the second shell 42, and to form the aforementioned expansion cavity 4a between the first shell 41 and the outer side 4312 of the cover. Figure 8 As shown, the battery module 6 is preferably sandwiched and positioned between the cover 43 and the second shell 42 .

[0025] Preferably, if Figure 8 And with Figure 2 As shown, the back cover 3, the second shell 42, the power cavity 4b, the cover 43, the expansion cavity 4a and the first shell 41 are stacked in sequence in one direction (for example, upward), and the first shell 41 is away from the back cover 3. Among them, the first shell 41 is provided with the aforementioned operation port 411, the second shell 42 is provided with the aforementioned wiring port 421, and the cover 43 is as shown. Figure 5 As shown, the aforementioned communication port 4311 is provided.

[0026] It is worth noting that if Figures 3 to 8 As shown, the cover body 43 has a cover plate 431 and a wall 432 connected to the cover plate 431, that is, the wall 432 surrounds the cover plate 431. The cover body outer side 4312 can be the outer side of the entire cover body 43, that is, the outer side of the cover plate 431 plus the outer side of the wall 432, or it can be only the outer side of the cover plate 431, and the present invention is not limited to this. An inner shell surface 422 of the second shell body 42 is provided with a groove 4221, such as Figure 3 As shown, the groove 4221 is in a surrounding shape, so the cover body 43 is suitable for being embedded and fixed in the groove 4221 with the surrounding wall 432 , so that the cover body 43 covers the inner shell surface 422 of the second shell 42 .

[0027] In order to make the expansion assembly of the present invention waterproof, in addition to adding a waterproof glue (not shown) in the groove 4221 so that the wall 432 and the groove 4221 can be waterproofed by the waterproof glue, Figure 3 and Figure 8 As shown, a gasket 45 of elastic material is added to the vicinity of the cover plate 431, and the card reading module 5 is located in the gasket 45; the first shell 41 is provided with a convex rib 412 that is circled and protrudes corresponding to the gasket 45, and the convex rib 412 is pressed against the gasket 45 with its protruding end when the expansion box 4 is assembled. At this time, the gasket 45 will be elastically concave due to the squeezing of the convex rib 412, thereby achieving a waterproof effect.

[0028] In addition, if Figures 8 to 10As shown, the aforementioned operation port 411 is exposed outside the expansion box 4. In order to make the operation port 411 waterproof, a convex rib 413 can be provided on the outside of the first shell 41 to surround the corresponding operation port 411 and be in a convex shape; and a door cover 44 that can be opened and closed can be provided at the position corresponding to the operation port 411 of the expansion box 4, and a gasket 46 made of elastic material corresponding to the convex rib 413 is attached to the inner surface of the door cover 44. In this way, as long as the door cover 44 is closed, the convex rib 413 can be pressed on the gasket 46 with its convex end, and the gasket 46 will be squeezed by the convex rib 413 and elastically concave accordingly, thus achieving a waterproof effect.

[0029] For example Figure 2 As shown, when the expansion box 4 is fixed to the outer cover surface 32 of the back cover 3 corresponding to the expansion window 31, in order to produce a waterproof and dustproof effect between the expansion box 4 and the periphery of the expansion window 31 of the back cover 3, a gasket 47 can be added to the adjacent surface of the expansion box 4 for adjacent to the back cover 3, so as to utilize the gasket 47 to produce a waterproof and dustproof effect between the expansion box 4 and the back cover 3.

[0030] The above is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural changes made by using the description and drawings of the present invention are also included in the scope of the rights of the present invention and are hereby stated.
