DETAILED DESCRIPTION OF THE INVENTION
The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.
FIG. 2 shows a mobile phone 100 (electronic device) of the invention, comprising a body 110 and a cover 120. The cover 120 pivots on the body 100. The body 110 comprises a control interface 130 disposed thereon. The cover 120 comprises a display 140 and an opening 150 disposed thereon.
FIG. 3 shows an inner structure of the cover 120 of the invention. The cover 120 comprises a first housing 121, a second housing 122, a chassis 124, a circuit board 123, a card-receiving device 200, the display 140 (with reference to FIG. 2) and a SIM card (card) 201. The chassis 124, the circuit board 123, the card-receiving device 200 and the display 140 are disposed between the first housing 121 and the second housing 122. The card-receiving device 200 corresponds to the opening 150. The circuit board 123, the card-receiving device 200 and the display 140 are disposed on the chassis 124. The SIM card 201 is disposed in the card-receiving device 200.
FIG. 4 is an exploded view of the chassis and the card-receiving device. The card-receiving device comprises a tray 210, a stopper 220, a resilient member 240 and guide grooves 231 and 232. The tray 210 comprises a base 211, an abutting portion 212 and a holding portion 213. The base 211 is planar, the abutting portion 212 is disposed on a first side thereof, the holding portion 213 is disposed on a second side thereof, and the first side is opposite to the second side. The SIM card 201 is supported by the base 211 comprising a conductive portion 202. The stopper 220 is formed on the chassis 124, comprising a cantilever beam 221 and a stopping portion 222. The stopping portion 222 is formed on an end of the cantilever beam 221. A first end of the resilient member 240 is connected to the chassis 124, and a second end thereof abuts the abutting portion 212. A connecting portion 241 is formed on the chassis 124 connecting the resilient member 240. A coupling portion 1231 is disposed on the circuit board 123 (with reference to FIG. 3) corresponding to the SIM card 201.
FIG. 5a is an assembly view of the chassis and the card-receiving device, wherein the tray 210 and the SIM card 201 are in a second position. An end of the resilient member 240 is connected to the connecting portion 241, and another end thereof abuts the abutting portion 212. The coupling portion 1231 corresponds to the conductive portion 202 to couple the SIM card 201 and the circuit board (not shown).
With reference to FIG. 5b, during removal of the SIM card 201, the holding portion 213 moves the tray 210 and the SIM card 201 to a first position. Simultaneously, the abutting portion 212 pushes the resilient member 240, which is deformed to provide a recovery force (elastic force).
With reference to FIG. 5c, after the tray 210 is released, the resilient member 240 pushes the tray 210 to the second position by the recovery force. Simultaneously, the SIM card 201 moves toward the second position, stopped by the stopping portion 222 of the stopper 220 (with reference to FIG. 5d, which is an enlarged view of portion A of FIG. 5c), and partially ejected from the opening 150 (with reference to FIG. 6). Thus, the SIM card can be easily removed from the opening 150.
After the SIM card 201 is removed from the opening 150, another SIM card 201′ is inserted into the opening 150 and pushed to the second position (with reference to FIG. 5e). FIG. 5f is an enlarged view of portion B of FIG. 5e, wherein when the SIM card 201′ is inserted, the insertion force overcomes the resistance of the stopper 220, and the cantilever beam 221 deforms upward. Thus, the SIM card 201′ can be pushed to the second position.
In the embodiment of the invention, the resilient member is a metal stick disposed between the chassis and the tray, wherein when the tray moves to the second position, the metal stick is compressed and bended for storing elastic force. However, the invention is not limited. The resilient member can be selected from other types of springs.
The invention provides easier SIM card swap, and increases the convenience of the mobile phone. Additionally, the SIM card is prevented from dropping during removal.
The card-receiving device of the invention can be utilized with other cards, such as memory cards. Additionally, the card-receiving device can be disposed in a personal digital assistant (PDA) or a notebook.
In the embodiment described, the SIM card 201 is disposed between the base 211 and the circuit board. However, FIG. 7a shows a modified embodiment of the invention, wherein the base 211′ is between the SIM card 201 and the circuit board. The base 211′ comprises a through hole 214. The chassis 124 comprises a stopper 220′ for stopping the SIM card 201. When the SIM card 201 is moved toward the second position with the tray 210′, the SIM card 201 is stopped by the stopper 220′ and partially ejected from the opening 150.
FIG. 7b is an assembly view of the modified embodiment in FIG. 7a, wherein the coupling portion 1231 passes the through hole 214, and couples the conductive portion 202 of the SIM card.
While the invention has been described by way of example and in terms of the preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
