Description

1. TECHNICAL FIELD

This exemplary disclosure generally relates to protective cover mechanisms used in electronic devices (e.g. mobile phones).

2. DESCRIPTION OF RELATED ART

Portable electronic devices such as mobile phones and personal digital assistants (PDAs) are now widely used. Most of these portable electronic devices include a touch screen and a touch stylus. The portable electronic device usually defines an accommodating hole to receive the stylus.

However, when the stylus is taken out for use, the accommodating hole is exposed to the outside, allowing contaminants such as dust and moisture to enter. The contaminants could negatively affect the performance of the portable electronic device.

Therefore, there is room for improvement within the art

DETAILED DESCRIPTION

In this exemplary embodiment, the protective cover mechanism is applied to a portable electronic device such as a mobile telephone. The mobile telephone described herein is a representation of the type of portable electronic device that may benefit from the exemplary embodiment. However, it is to be understood that the exemplary embodiment may be applied to any type of hand-held or portable device including, but not limited to, the following devices: radiotelephones, cordless phones, personal digital assistants, and the like. Accordingly, any reference herein to the mobile telephone should also be considered to apply equally to other portable electronic devices.

FIG. 1 shows an exploded perspective view of a protective cover mechanism 100 including a housing 10, a protective cover 20 and a latching pole 30. The housing 10 can be a back housing or a main body of a portable electronic device. The housing 10 includes a base wall 11, a peripheral wall 13 and a holding portion 15. The base wall 11 can be substantially rectangular. The peripheral wall 13 extends substantially perpendicularly from the peripheral edge of the base wall 11. The peripheral wall 13 includes an end wall 131 extending perpendicularly from an end portion of the base wall 11 and two side walls 133 extending perpendicularly from two sides of the base wall 11 and connecting the two ends of the end wall 131. Accordingly, the peripheral wall 13 forms two corner portions 135 adjacent to the two ends of the end wall 131.

The holding portion 15 is adjacent to one corner portion 135 of the housing 10, thereby forming a receiving space 150 cooperating with the base wall 11 and the corner portion 135. The holding portion 15 can be a substantially L-shaped board extending substantially perpendicularly from the base wall 11. The two ends of the holding portion 15 connect with the end wall 131 and one adjacent side wall 133. The holding portion 15 includes a first holding board 151 parallel to the end wall 131 and a second holding board 152 connects substantially perpendicularly with the first holding board 151 and substantially parallel to the side wall 133. The distal end of the first holding board 151 connects substantially perpendicularly with the adjacent side wall 133. The distal end of the second holding board 152 connects substantially perpendicularly with the end wall 131. Accordingly, the first holding board 151, the second holding board 152, the base wall 11, the end wall 131 and the adjacent one side wall 133 together form the receiving space 150. The first holding board 151 defines a through hole 153 axially perpendicular to the surface of the end wall 131.

An opening 16 is defined through one corner portion 135 of the peripheral wall 13 and communicates with the receiving space 150 for inserting an accessory of the portable electronic device such as a stylus (not shown). It is noteworthy that the opening 16 can also be for an external interface (e.g., universal serial bus (USB) or a port for electrically connecting with external devices (e.g., printers), accessories (e.g., USB flash drives) or other electronic devices.

A supporting board 17 extends perpendicularly from the sidewall 133 adjacent to the opening 16 and located within the receiving space 150. The supporting board 17 is for supporting and guiding the protective cover 20. The distal end of the supporting board 17 is bent toward the first holding board 151 side to form a clapboard 18 for facilitating the stylus being inserted into the receiving space 150 and passing through the corresponding through hole 153 of the first holding board 151. A fixing hole 19 is defined in the base wall 11 adjacent to the opening 16 of the corner portion 135 for fixing the latching pole 30. The latching pole 30 is a substantially cylindrical post and integrally fixed to the fixing hole 19 of the housing 10 for slidably or rotatably assembling the protective cover 20 to the housing 10 to cover the opening 16 of the housing.

Referring also to FIG. 2, the protective cover 20 is slidably or rotatably assembled to the latching pole 30 and the housing 10, and is received within the receiving space 150 to cover the opening 16 of the housing 10. The protective cover 20 can be made of elastic material such as rubber and includes a substantially triangular frame 21 and a substantially triangular base board 22. The frame 21 includes a substantially arc-shaped covering wall 211 and a substantially L-shaped enclosing wall 212 connecting with the two ends of the covering wall 211. The covering wall 211 has substantially the same shaped as the opening 16 of the housing 10 such that a protective cover 20 is assembled to the housing 10, the protective cover 20 is substantially hermetically received within the opening 16 of the housing 10. A plurality of ridges 215 protrude from an outer surface of the covering wall 211 adjacent one end thereof for facilitating the user's moving of the protective cover 20. The base board 22 includes a latching slot 23 defined therethrough corresponding to the latching pole 30. The latching slot 23 includes a first latching end 231, a middle guiding slot 235, and an opposite second latching end 233. Both the first latching end 231 and the second latching end 232 are substantially a curved hole shaped so that it can communicate with the middle guiding slot 235. The diameters of the first latching end 231 and the second latching end 232 are substantially the same as the diameter of the latching pole 30 but slightly larger than that of the middle guiding slot 235.

Referring to FIGS. 3 and 4, to assemble the protective cover mechanism 100, the protective cover 20 is assembled to the housing 10 and inserted into the opening 16 of the peripheral wall 13 with the enclosing wall 212 abutting the supporting board 17. The latching pole 30 passes through the latching slot 23 of the protective cover 20 and is fixed to fixing hole 19 of the housing 10. With an external force, push the protective cover 20 toward the receiving space 150 until the protective cover 20 is totally accommodated within the receiving space 150, and the latching pole 30 slides along the latching slot 23 and latches into the second latching end 233. Then, the protective cover 20 is assembled to the housing 10 to cover the opening 16 and is accommodated with in receiving space 150.

Referring also to FIG. 5, to release the protective cover 20 for exposing the opening 16, the protective cover 20 is pushed to move away from the housing 10. The latching pole 30 is disengaged from the second latching end 233 and slides toward the opposite first latching end 231, and latches into the first latching end 231 of the protective cover 20 to expose the opening 20, facilitating an easy removal of stylus from the housing 10 or allowing the stylus to be put away.

It is to be understood that the latching pole 30 may be made of elastic material such as rubber, and formed integrally with the housing 10 within a single mold. Alternatively, the protective cover 20 can be rotatably hinged to the latching pole 30 to cover the opening 16 of the housing 10 or expose the opening 16.

It is to be understood that even though numerous characteristics and advantages of the exemplary embodiments have been set forth in the foregoing description, together with details of structures and functions of various embodiments, the 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 exemplary invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
