1. Technical Field
The present disclosure relates to electronic devices, and particularly to an electronic device having a protecting cover.
2. Description of Related Art
Electronic device, such as a DVD player, includes a housing, an illuminating unit housed in the housing, and a transparent protecting cover secured to the housing and corresponding to the illuminating unit. The protecting cover includes a hook member. The housing defines an opening for allowing the protecting cover to be received therein, and includes a latching member arranged adjacent to the opening. The latching member corresponds to the hook member and hooks the hook member to secure the protecting cover to the housing. However, if the protecting cover is made of polymethyl methacrylate, which is very brittle, the protecting cover may be broken when being secured to the housing by the hook member engaging with the latching member.
Therefore, there is room for improvement in the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the three views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to
The protecting cover 50 is used for allowing light emitted by the illuminating unit 40 to be transmitted therethrough. The protecting cover 50 includes a base 510 and a window 520 arranged on the base 510. The base 510 is substantially rectangular, and includes a first end 511 and a second end 512 opposite to the first end 511. In the embodiment, the window 520 is arranged at the middle of the base 510. When viewed from a front surface 513 of the base 510, the window 520 protrudes out of the front surface 513 of the base 510; When viewed from a rear surface 514 of the base 510, the window 520 is recessed in the rear surface 514 of the base 510. In the embodiment, the protecting cover 50 is made of polymethyl methacrylate and is substantially transparent.
The housing 101 is substantially rectangular, and includes a top case 10 and a bottom case 20. The top case 10 engages with the bottom case 20 to define a receiving space 102 (see
The top case 10 includes a top wall 110 and four sidewalls extending from the edges of the top wall 120. The top wall 110 is substantially rectangular, and defines an opening 112. The opening 112 is used for receiving the window 520 and allows the window 520 to be exposed out of the housing 101. The size of the opening 112 is smaller than the size of the base 510, but is larger than the size of the window 520. In the embodiment, the opening 112 is substantially rectangular, and is arranged adjacent to a vertex of the top wall 110.
The bottom case 20 includes a bottom wall 210 corresponding to the top wall 110 and four side portions 220 extending from rims of the bottom wall 210. The four side portions 220 correspond to the four sidewalls 120. An abutting assembly 230 is secured to an inner surface of the bottom wall 210 and corresponds to the opening 112. The abutting assembly 230 includes a first abutting member 232 and a second abutting member 234. The first abutting member 232 is parallel to and spaced from the second abutting member 234. A distance between the first and second abutting members 232, 234 is less than the distance between the first and second ends 511, 512. In the embodiment, the first abutting member 232 is substantially rectangular and perpendicular to the bottom wall 210, the second abutting member 234 is substantially T shaped. The second abutting member 234 includes a connecting portion 235 perpendicularly extending from the bottom wall 210 and a resisting portion 236 arranged at an end of the bottom wall 210 away from the bottom wall 210. A rib 240 protrudes form the bottom wall 210 and connects with an end of the first abutting member 232 opposite to the second abutting member 234. The rib 240 is used to enhance the stiffness of the first abutting member 232.
The illuminating unit 40 is arranged adjacent to a side portion 302 of the circuit board 30 and corresponds to the opening 112. The circuit board 30 defines a through hole 310, and the illuminating unit 40 is arranged between the through hole 310 and the side portion 302. The distance between the through hole 310 and the end portion 302 is greater than the distance between the first and second abutting member 232, 234, such that the resisting portion 236 passes through the hole 310, and the first abutting member 232 abuts the end portion 302 of the circuit board 30.
