Card tray ejection mechanism and electronic device using the same

An electronic device, comprising:

• a housing;
• and
• a card tray ejection mechanism for holding an electronic card, the card tray ejection mechanism being accommodated in the housing;
• wherein the card tray ejection mechanism comprises a base, a tray for receiving the electronic card slidably received in the base, at least one driving mechanism resisting against the tray and for driving the tray being ejected out of the housing, the at least one driving mechanism comprises a driving member and a transmitting member rotatably coupled to the driving member, the driving member is configured to drive the transmitting member rotating, and the transmitting member is configured to resist against the tray and to drive the tray being ejected out of the housing when being rotated;
• wherein the driving member comprises an electromagnet and a driving post slidably received in the electromagnet, and the electromagnet is configured to drive the driving post sliding thereinto when being provided with a current.

A card tray ejection mechanism for ejecting a tray slidably received in a housing of an electronic device, comprising:

• a first elongated member rotatably mounted to the housing, the first elongated member comprising a first end portion resisting against a side of the tray, a second end portion opposite to the first end portion and a pivoting rod located between the first and second end portions;
• a second elongated member rotatably connected to the second end portion;
• and
• a driving member configured to drive the second elongated member to move longitudinally;
• wherein when the second elongated member is driven to move longitudinally by the driving member, the first elongated member is driven to rotate around the pivoting rod by the second elongated member, and the tray is driven to be ejected out of the housing;
• wherein the first elongated member comprises a post and a resisting portion, one end of the post is rotatably coupled to the driving post, the resisting portion is slidably received in the other end of the post and resisting against the tray, the post and the resisting portion are driven to rotate when the second elongated member is driven to move longitudinally by the driving member.
