DETAILED DESCRIPTION

Referring to FIGS. 1 and 2, a cover 100 of an electronic device according to an exemplary embodiment includes an upper cover 200 clasped to a body (not shown) of the electric device, a lower cover 300 fixed to the body, a fixing member 400, and a sliding member 500. The fixing member 400 is fixed to the lower cover 300. The sliding member 500 is positioned between the lower cover 300 and the fixing member 400. An edge of the lower cover 300 defines a notch 302. The sliding member 500 is formed with a toggle 502 that is slidably received in the notch 302.

Referring to FIG. 3, the upper cover 200 includes a number of blocks 202 protruding therefrom. Referring to FIG. 7, each block 202 defines an opening 204 facing the lower cover 300.

The lower cover 300 is formed with a number of protruding tabs 304 and a number of protruding posts 306. The protruding tabs 304 extend from the edge of the upper cover 200 where the notch 302 is formed and reside at the inner side of the lower cover 200. Each protruding tab 304 defines a threaded hole (not labeled) allowing for the engagement of a screw, to fix the lower cover to a body of the electronic device. The protruding posts 306 protrude from the inner surface of the lower cover 300. Each protruding post 306 defines a threaded hole 308.

The sliding member 500 is an elongated plate. The sliding member 500 includes a number of latching portions 504 protruding from an edge thereof. The latching portions 504 are respectively slidably received in the corresponding openings 204 of the upper cover 200. The sliding member 500 further includes a restricting member 506 opposite to the fixing member 400. Two through holes 508 are respectively defined at opposite sides of the restricting member 506. Referring to FIG. 4, the toggle 502 defines a slot 510. A user can push the toggle 502 to slide the sliding member 500.

The fixing member 400 can be made of elastic plastic and is an elongated plate. The fixing member 400 includes a base 402 and a pair of fixing portions 404 at two opposite ends of the base 402.

The fixing portions 404 each define a fixing hole 406, which allow the screws to extend through when screwed into the corresponding threaded holes 308, thereby fixing the fixing member 400 to the lower cover 300.

The base 402 defines a substantially rectangular restricting groove 408. A pair of smooth protrusions 410 protrudes from opposite sidewalls of the restricting groove 408. The protrusions 410 divide the restricting groove 408 into two hollow portions 412 at opposite sides of the protrusions 410 and a hollow space 414 between the two protrusions 410. The hollow portions 412 can receive the restricting member 506 therein. The protrusions 410 are configured for preventing the restricting member 506 from freely moving between the hollow portions 412. The protrusions 410 can be urged to elastically deform, allowing the restricting member 506 to move between the hollow portions 412.

In the embodiment, the base 402 further defines a pair of slots 416 adjacent to the restricting groove 408. The slots 416 are symmetrically positioned at opposite sides of the restricting groove 408. An extending direction of the slots 416 is parallel to a movement direction of the restricting member 506. The slots 416 enable the protrusions 410 and the sidewall, where the protrusions 410 are located, as a whole to elastically deform.

Referring to FIG. 4, the base 402 further defines a receiving space 418 opposite to the lower cover 300 to receive the sliding member 500. The base 402 further includes a pair of guiding posts 420 protruding from the bottom of the receiving space 418. The guiding posts 420 are respectively received in the through holes 508 of the sliding member 500. The size of the through holes 508, measured along the movement direction of the restricting member 506, is greater than the guiding post 420.

FIGS. 4 and 5 show the toggle 502 in a latching position. The latching portions 504 are received in the corresponding openings 204. The restricting member 506 is received in the hollow portion 412 adjacent to the opening 204. Because of the protrusions 410, the restricting member 506 is retained in the hollow portion 412 adjacent to the opening 204 without external force.

Referring to FIGS. 5 to 7, to detach the upper cover 200, the toggle 502 can be slid from the latched position to an unlatched position as shown in FIGS. 6 and 7. During the sliding of the toggle 502, the protrusions 410 are urged to elastically deform, until the restricting member 506 passes the hollow space 414 and enters the other hollow portion 412 away from the opening 204. When the toggle 502 slides to the unlatched position, the latching portions 504 move out of the openings 204. The upper cover 200 is then free from the limitation of the latching portions 504 and can be detached from the body of the electronic device.

The sliding member 500 of the cover 100 is not only able to cover the notch 302, but also able to connect the upper cover 200 to the lower cover 300, thus to fix the upper cover 200 to the body of the electronic device more firmly.

It is to be understood, however, that even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the present disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
