detailed description

The present invention will be further described below in conjunction with the embodiments.

Embodiment 1 As shown in FIG. 1 to FIG. 2, the protective casing of the mobile device includes a lower cover 20 and an upper cover 10 as a frame. The upper edge of the inner side wall of the upper cover 10 is convexly provided with a circle. The lower end surface of the upper cover 10 is provided with an outer slide rail 11 , and the lower cover 20 includes an outer frame 201 and a back plate 202 surrounded by the outer frame 201 . The upper end surface of the outer frame 201 is provided with an inner slide rail 21 . The outer slide rail 11 is in close cooperation with the inner slide rail 21. Compared with the upper cover 10 and the lower cover 20 of the existing protective case, the upper cover 10 and the lower cover 20 of the protective cover are closely matched by the sliding rail, and the notch of the outer sliding rail 1 1 faces outward, and the inside is closed. The notch of the slide rail 21 faces Since the upper edge of the inner side wall of the upper cover 10 is convexly provided with a collar, the ring restricts the mobile device from entering and exiting only from the lower end surface of the upper cover 10, so that the mobile device is first removed from the upper cover 10 during installation. The lower end surface of the lower cover 20 is inserted into the upper cover 10, and then the first end of the inner slide rail 21 of the lower cover 20 is inserted into the front end of the outer slide rail 11 of the upper cover 10, and only the lower cover 20 is required to be pushed down, so that the lower cover 20 passes the cooperation of the slide rails. Relatively speaking, the upper cover 10 slides. When the head end of the inner slide rail 21 is aligned with the end of the outer slide rail 11, the upper cover 10 and the lower cover 20 are closely matched to protect the mobile device; The opposite of the book installation can be performed. The protective case does not require special tools or techniques for installation or disassembly, and has a simple structure and is convenient to use. Moreover, the upper cover 10 and the lower cover 20 of the protective cover adopt a sliding manner, and the sliding rail is not damaged due to multiple disassembly and assembly, and the service life is relatively long.

Further, the first end of the inner slide rail 21 of the lower cover 20 defines a recessed recess 22, and the end of the outer slide rail 11 of the upper cover 10 is provided with the limit recess 22 The limiting protrusion 12, the lower cover 20 slides relative to the upper cover 10. When the leading end of the inner sliding rail 21 is aligned with the end of the outer sliding rail 11, the limiting protrusion 12 is caught in the limiting recess 22, so that the upper cover 10 and the upper cover 10 The lower cover 20 is more stable.

Further, the end of the outer slide rail 11 of the upper cover 10 is provided with a stopper portion 13. When the first end of the inner slide rail 21 slides to the end of the outer slide rail 11, the stopper portion 13 blocks the inner slide rail 21 from sliding. The blocking portion 13 can function as a limit.

Further, the side wall of the upper cover 10 is provided with a wiring hole 14 adapted to the connection port of the mobile device, and the mobile device is generally provided with a data transmission interface, an audio interface, a charging interface, etc. on the side wall. The side wall of the 10 is provided with a wiring hole 14 adapted to the wiring port of the mobile device, and can be connected without disassembling the protective case, which is more convenient to use. Further, the side wall of the upper cover 10 is provided with a button hole 15 adapted to the button of the mobile device, and the mobile device is generally provided with a power switch button and a sound adjustment button on the side wall, and the upper cover 10 The button hole 15 corresponding to the button of the mobile device is opened on the side wall, and the button can be controlled without disassembling the protective case, which is more convenient to use.

Say

Further, the button hole 15 is embedded with a button protection cover 16 adapted to the button pressed by the mobile device, and can protect the button of the mobile device and facilitate operation.

Book

Further, the back plate 202 is provided with a lens through hole 17 adapted to the imaging lens of the mobile device, which is convenient to use and enhances practicability. The SIM card replacement hole 18 is also formed on the side wall of the protective shell, and the SIM card can be directly replaced without disassembling the protective shell, which is convenient to use. Of course, the above-mentioned wiring hole 14, button hole 15, button protection cover 16, lens through hole 17 and SIM card replacement hole 18 need to be correspondingly arranged according to a specific mobile device. Further, the outer frame 201 and the back plate 202 are integrally formed, and the outer frame 201 and the back plate 202 are integrally formed, which is simple in production and processing, and can reduce cost. Further, the lower cover 20, according to different functional requirements, only needs to replace the lower cover 20 provided with the corresponding extended functional component, without having to replace the entire protective casing, and the protective casing has good function expandability. Embodiment 2: As shown in FIG. 3, the difference between the embodiment and the first embodiment is that the outer frame 201 and the back plate 202 are separable, and the back plate 202 is embedded in the outer frame 201, according to different functions. In the requirement, only the backboard 202 provided with the corresponding extensible features needs to be replaced, and the entire protective casing does not have to be replaced, and the protective casing has good function expandability. Further, the backboard 202 is provided with an extended functional component including a support frame, a handle or a lens mount. Mobile devices generally have functions such as games and video playback. However, the mobile device has a relatively simple structure for the portable device. For example, when watching a video with a mobile device, there is no support frame fixed, which is inconvenient to use; when playing games with a mobile device, there is no handle provided, which is inconvenient to control. The back plate 202 of the protective cover can be provided with an extended functional component including a support frame, a handle or a lens mount, and the back plate 202 is easily disassembled, and the different back cover plates 202 can be replaced according to different functional requirements, so that the protective cover can be While protecting mobile devices, their scalability features are also fully utilized.

The other content of this embodiment is the same as that of the first embodiment, and details are not described herein again.

The above is only a preferred embodiment of the present invention. For those skilled in the art, depending on the idea of the present invention, there will be changes in the specific embodiments and application scope, and the contents of this specification should not be construed as Limitations on the present invention.
