Description of the invention: [Technical field to which the invention pertains] # • The present invention relates to a protective cover structure, and more particularly to a protective cover structure applied to a portable electronic device. [Prior Art] At present, more and more portable electronic devices (such as mobile phones, PDAs, music players, etc.) use universal serial bus (USB) technology, and USB-based portable electronic devices are used in the case. One part of the body has a USB interface. In addition, electronic devices often have interfaces for other uses, such as mouse sockets. In order to prevent substances such as dust from falling into the above interface when not in use, a cover is usually provided at such an interface. Referring to FIG. 1 , a protective cover structure 10 of a conventional electronic device includes a cover 12 , a holding portion 122 disposed on the cover 12 , a body 14 , and a housing disposed thereon A slider 142 in the slider 14 142 has a stopper 144 protruding from the slider 142. The latching portion 122 can slide along the slider 142. When the slider 142 slides a certain distance toward the outside of the housing 14 , the latching portion 122 abuts against the stopper 144 on the slider 142 to block the cover. The board 12 is further pulled out. Although the protective cover structure 10 can realize the closing and pulling of the body relative to the housing 14, the protective cover structure 10 is apt to disengage the cover 12 from the housing 14 due to excessive force. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a protective cover structure that is not easy to fall off. 0 6 200950643 A protective cover structure, 1 j /, including a protective cover, the early morning || # ffi & One of the 0 ^ ^ 濩 濩 用于 用于 用于 用于 用于 用于 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , Physically, detached. The elastic piece is used for stopping the protective cover and the housing. When the protective cover structure needs to use the connection π, the protective cover is pulled by the protective cover in the direction of sliding out of the housing. The sliding direction of the bone protection cover sliding '# when the elastic piece is in contact with the sliding portion' is prevented by the elastic piece from continuing to slide out of the housing, that is, preventing the protective cover from continuing to slide out of the housing . At the same time, due to the abutment of the elastic piece and the interface, the force of the elastic piece against the sliding portion can be enhanced to effectively prevent the protective cover from being detached from the housing. [Embodiment] The protective cover structure of the present invention is suitable for use in an electronic device such as a mobile phone, a PDA, or a computer. This embodiment is described by taking a protective cover structure applied to a mobile phone as an example. Referring to FIG. 2 and FIG. 3', the electronic device 20 includes an upper casing 22, a lower casing 24, a protective cover structure 26 and an interface 28. The upper case 22 is disposed on the lower case 24. A plurality of buttons 222 and a display screen 242 are disposed on the upper casing 22. The protective cover structure 26 is configured to shield the interface 28 disposed in the lower casing 24. Referring to FIG. 3, the lower casing 24 is substantially a square frame, and includes a bottom wall 242 and a bottom plate. A peripheral wall 244 on the wall 242. An opening 2442 is formed in the peripheral wall 244. The opening 2442 corresponds to the interface 28 and is set in the 200950643'. The protective cover structure 26 includes a protective cover 262 and a resilient piece 264. * The protective cover 262 is generally a square plate-like body that includes a surface 2622 toward the lower casing 24. One surface of the surface 2622 extends to an engaging portion 2624, and the other side extends a sliding portion 2626. In this embodiment, the engaging portion 2624 is a latch, and the sliding portion 2626 is a square plate-like body extending from the surface 2622 toward the housing. The engaging portion 2624 is engaged with the lower case 24 (see Fig. 4). A square notch 2628 is defined in the sliding portion 2626, and the notch 2628 is engaged with the elastic piece 264 (see FIG. 4). The elastic piece 264 includes a fixing portion 2642, a stopping portion 2644 and a resisting portion 2646. The fixing portion 2642 is substantially a flat body parallel to the bottom wall 242 of the lower casing 24, and the fixing portion 2642 is fixed to the bottom wall 242. Referring to FIG. 6, the stopper portion 2644 is formed by bending one end of the fixing portion 2642 in a direction away from the bottom wall 242. The angle A between the stopping portion 2644 and the bottom wall 242 is less than 90 degrees, and the stopping portion 2644 passes through the notch 2628 to stop the sliding portion 2626 from sliding off the inside of the lower casing 24. The abutting portion 2646 is formed by bending one end of the stopper portion 2644 toward the bottom wall 242, and the abutting portion 2646 is substantially parallel to the fixing portion 2642. The abutting portion 2646 is in opposition to the interface 28 (see Fig. 6). Referring to FIG. 4 to FIG. 6 , when the protective cover structure 26 is assembled to the lower casing 24 , the fixing portion 2642 of the elastic piece 264 is fixed (hot-melt or ultrasonically welded) to the bottom wall. The sliding portion 2626 extends into the lower casing 24 through the opening 2442. At this time, the stopping portion 2644 is located in the notch 2628 and the engaging portion 2624 is engaged with the lower casing 24; 8 200950643 _ The interface 28 is disposed in the lower casing 24. At this time, the interface 28 is abutted against the abutting portion 2646 of the elastic piece 264, so that the protective cover structure 26' is assembled on the lower casing 24. The interface 28 is disposed in the lower casing 24. The interface 28 is fixed to a circuit board (not shown) in the lower casing 24. When the interface 28 is to be used, the engaging portion 2624 is disengaged from the lower casing 24, and then the protective cover 262 is pulled in a direction in which the protective cover 262 slides out of the lower casing 24, thereby driving the sliding portion. 2626 moves the protective cover 262 in a direction in which the lower housing 24 slides out, thereby exposing the interface 28 for use of the interface 28. When the protective cover structure 26 is used, the protective cover 262 is pulled in the direction in which the protective cover 262 slides out of the lower cover 24, so that the sliding portion 2626 is slid in the sliding direction of the protective cover 262. When the stopping portion 2644 of the elastic piece 264 abuts against the sliding portion 2626, the sliding portion 2626 is prevented from continuing to slide out of the lower casing 24 by the stopping portion 2644, that is, the protective cover 262 is prevented from continuing from the lower casing. Slide out within 24. And because the abutting portion 2646 of the elastic piece 264 abuts against the interface 28, the force of the stopping portion 2644 against the sliding portion 2626 can be enhanced, thereby effectively preventing the protective cover 262 from being inside the lower casing 24. Get rid of. In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application. 9 200950643 [Simplified illustration of the drawings] Fig. 1 is a schematic view of a conventional protective cover structure; 'Fig. 2 is a schematic view of a protective cover structure of a preferred embodiment of the present invention assembled to a portable electronic device; 2 is a schematic exploded view of the protective cover structure and the lower casing and the interface of the portable electronic device; FIG. 4 is a schematic view showing the protective cover structure shown in FIG. 3 assembled on the lower casing, FIG. 5 is a schematic view of FIG.
