DETAILED DESCRIPTION
Referring to FIGS. 2 to 6, FIG. 2 is a perspective view illustrating a card installation device 3 according to an embodiment of the invention, FIG. 3 is an exploded view illustrating the card installation device 3 shown in FIG. 2, FIG. 4 is a partial assembly view illustrating the card installation device 3 shown in FIG. 3, FIG. 5 is a schematic diagram illustrating a first card 4a and a second card 4b installed in the casing 30 of the card installation device 3 shown in FIG. 2, and FIG. 6 is a schematic diagram illustrating the first card 4a and the second card 4b pushed out of the casing 30 by the pushing member 32 shown in FIG. 5.
As shown in FIGS. 2 to 4, the card installation device 3 comprises a casing 30, a pushing member 32, a resilient plate 34, two resilient members 36 and a fixing member 38. In this embodiment, the casing 30 comprises an upper casing 300 and a lower casing 302, wherein the upper casing 300 and the lower casing 302 are detachably combined together. The casing 30 has a first accommodating recess 304 and a second accommodating recess 306, wherein a width W2 of the second accommodating recess 306 is different from a width W1 of the first accommodating recess 304 and the first accommodating recess 304 and the second accommodating recess 306 are arranged up and down. In this embodiment, the first accommodating recess 304 is used for accommodating the first card 4a and the second accommodating recess 306 is used for accommodating the second card 4b. In practical applications, the first card 4a may be, but not limited to, a SIM card and the second card 4b may be, but not limited to, a Micro SD card. The first card 4a and the second card 4b also may be other memory cards. Since a size of the first card 4a is larger than a size of the second card 4b, the width W1 of the first accommodating recess 304 is also larger than the width W2 of the second accommodating recess 306. It should be noted that the casing 30 may have only the first accommodating recess 304 or only the second accommodating recess 306, or the casing 30 may have more than two accommodating recesses for more than two cards with different sizes. In other words, the number of accommodating recesses of the casing 30 may be determined based on the types of the cards and is not limited to the embodiment shown in FIGs. 2 to 6.
A pushing end 320 of the pushing member 32 is movably disposed in the casing 30. When the first card 4a is accommodated in the first accommodating recess 304 or the second card 4b is accommodated in the second accommodating recess 306, the pushing end 320 is used for pushing the first card 4a or the second card 4b. In this embodiment, the pushing end 320 has a first pushing surface 320a and a second pushing surface 320b corresponding to the first card 4a and the second card 4b with different sizes, respectively. The first pushing surface 320a is used for pushing the first card 4a when the first card 4a is accommodated in the first accommodating recess 304, and the second pushing surface 320b is used for pushing the second card 4b when the second card 4b is accommodated in the second accommodating recess 306.
As shown in FIGS. 2 and 4, one end of the resilient plate 34 is fastened on the upper casing 300 of the casing 30 and located over the first accommodating recess 304 and the second accommodating recess 306. In this embodiment, the resilient plate 34 can be pushed to deflect upwardly and then generates downward pressure. As shown in FIG. 5, a user can install the first card 4a and the second card 4b into the first accommodating recess 304 and the second accommodating recess 306 in a direction indicated by an arrow A1, respectively. A front end of the resilient plate 34 is arc-shaped so that the first card 4a and the second card 4b can push the resilient plate 34 upwardly during insertion. The resilient plate 34 is used for clamping the first card 4a when the first card 4a is accommodated in the first accommodating recess 304 and the resilient plate 34 is used for clamping the second card 4b when the second card 4b is accommodated in the second accommodating recess 306. As shown in FIGS. 3 and 4, the casing 30 has a protruding portion 308 and the pushing member 32 has a guiding groove 322. The protruding portion 308 is disposed in the guiding groove 322 and the fixing member 38 is fixed on the protruding portion 308 such that the pushing member 32 can move forward and backward with respect to the protruding portion 308 within the guiding groove 322. In practical applications, the fixing member 38 may be a screw, rivet or other engaging members.
The casing 30 may have two side walls 310 therein located at opposite sides of the protruding portion 308 and the pushing member 32 may have two side wings 324 located at opposite sides of the guiding groove 322 and opposite to the two side walls 310. Each of the resilient members 36 is disposed between one of the side walls 310 and one of the side wings 324 correspondingly. In other words, both ends of the resilient member 36 abut against the side wall 310 and the side wing 324, respectively. In practical applications, the resilient member 36 may be a spring or other resilient components. When the pushing member 32 is pressed to move with respect to the casing 30, the side wing 324 will compress the resilient member 36 while the pushing member 32 is moving. When the pushing member 32 is released, the compressed resilient member 36 will generate an elastic force for pushing back the pushing member 32 to the original position before being pressed.
The upper casing 300 of the casing 30 may have a holding portion 312 and the pushing member 32 may have a pressing portion 326 outside the casing 30. In this embodiment, the holding portion 312 and the pressing portion 326 both are, but not limited to, plate-shaped. The holding portion 312 and the pressing portion 326 can be used together for a user to operate the card installation device 3.
When the user wants to operate the card installation device 3 to install the first card 4a or the second card 4b into a card slot of an electronic device (see the card slots 10a, 10b shown in FIG. 1), he or she has to insert the first card 4a or the second card 4b into the first accommodating recess 304 or the second accommodating recess 306 of the casing 30 of the card installation device 3 in the direction indicated by the arrow A1, as shown in FIG. 5.
