1. Technical Field
The present disclosure relates to cover assemblies, and particularly to a cover assembly serving as a front panel of an optical disc playing device.
2. Description of Related Art
Digital Versatile Disc (DVD) players, computers or other electronic device often have a built-in optical drive such as a CD-ROM, a DVD-ROM, a CDRW and a DVDRW CD-ROM. In order to be able to use optical drives such as a DVD, a DVD-ROM, a CDRW and a DVDRW CD-ROMs and harmonize the entire appearance of the electronic device, it is necessary to cover the optical drive yet still allowing the drive to be able to open.
Usually, a cover assembly is arranged to cover the optical drive, the cover assembly includes a door and a rotation axis including a torsion spring. The rotation axis is accommodated in a shell of the electronic device, the door is fixed on the rotation axis by bolts and capable of rotating together with the rotation axis. During assembly, the rotation axis is accommodated in a shell, but the door must be assembled from the outside of the shell, and the operator must screw the bolts in the inside of the shell to fix the door on the rotation axis, which is complicated. 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 present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure, including the accompanying, is illustrated by way of example and not by way of limitation. 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
Referring to
The cover assembly 100 further includes a torsion spring 30 including a first torsion arm 31 and a second torsion arm 32. The torsion spring 30 is coiled around the protruding post 152, and the first torsion arm 31 is held by the first holder 162.
Referring to
The base 20 further includes a second holder 23 arranged in the inner side of the base 20, and the second torsion arm 32 is held by the second holder 23. The torsion spring 30 applies a pulling force to the cover 10.
When the cover 10 is pushed by the disc tray, the cover 10 pivots about the first pivot 141 and the second pivot 142 until the disc tray moves out from the opening 21. When the disc tray moves back, the cover 10 rotates back to its original position under the pulling force of the torsion spring 30.
In other embodiments, the first pivot 141 extends from the first end 121 instead of extending from the first arm 131, similarly, the second pivot 142 extends from the second end 122.
Because the cover 10 is made of elastic material, during assembly, the operator only needs to bend the cover 10 slightly, and assembles the first pivot 141 into the hole 223, and the second pivot 142 into the hole 224 from the opening 21. The operator does not need to screw the bolts in the inside of the base 20 to fix the cover 10. In this way, the assembly process is greatly simplified.
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.
