Electronic device providing data protection for inserted smartcard
View Patent ↗An electronic device includes a housing for safely breaking electronic communication with a smart card on removal from the electronic device. A safeguard structure rotates with respect to the housing to cover the smart card when inserted, and a switch breaks communication between the smart card and the electronic device when the safeguard structure is rotated away from the housing to enable removal of the smart card. The breaking of communication safely prevents damage to, or corruption of, data in the smart card upon removal from the electronic device.
1. An electronic device for communicating with a smart card comprising:
a housing defining an opening and receiving the smart card;
a safeguard structure rotatably connected to the housing to cover or uncover the opening; and
a switch received in the housing, wherein when the safeguard structure is rotated to uncover the opening, the safeguard structure contacts the switch to break a communication between the smart card and the electronic device, and wherein when the safeguard structure is rotated to cover the opening, the safeguard structure is separated from the switch to initiate the communication between the smart card and the electronic device;
wherein the safeguard structure further comprises a door and a touching arm protruding from a first surface of the door facing the smart card, when the door is opened, the switch is contacted by the touching arm to break the communication between the smart card and the electronic device.
2. The electronic device of claim 1 , wherein the touching arm comprises a joint portion and a touching portion, the joint portion protrudes from the first surface, the joint portion has a first end away from the door, and the touching portion protrudes from the first end, when the door is opened, the switch is contacted by the touching portion to break the communication between the smart card and the electronic device.
3. The electronic device of claim 2 , wherein the housing comprises a top cover, and a locating pin protruding from the top cover towards the touching arm, a locating portion protrudes from the touching arm, the locating portion is inserted into the locating pin to allow the safeguard structure to be rotated respect to the housing.
4. The electronic device of claim 3 , wherein the locating portion comprises a locating shaft protruding from the touching arm, and a stop block protruding from the locating shaft, the locating pin defines a shaft hole and a limit groove communicating with the shaft hole, the locating shaft is rotatably inserted into the shaft hole, the stop block received in the limit groove, when the locating shaft is rotated with respect to the locating pin, and the stop block is rotated with the locating shaft, and the stop block is stopped by the locating pin to prevent the locating shaft from being rotated when the locating shaft is rotated with the locating pin by an predetermined angle.
5. The electronic device of claim 4 , wherein the housing comprises a bottom cover assembled to the top cover, a rotating shaft protruding from the bottom cover, an end of the rotating shaft away from the bottom cover is inserted into the touching arm, to allow the safeguard structure to be rotated respect to the housing.
