## Abstract

A card tray withdrawing apparatus and communication device are provided. Herein, the card tray withdrawing apparatus includes a first interference part arranged at a first position in a housing, a second interference part arranged at a second position in the housing, and a button mounted on the housing, capable of moving from an initial position to the first position and capable of moving from the first position to the second position. The button moving to the first position interferes with the first interference part, and the first interference part turns on a circuit in the housing; and the button moving to the second position interferes with the second interference part, and the second interference part drives a card tray to be separated from a card slot. Herein, the communication device includes a housing, and further includes the card tray withdrawing apparatus.

## Claims

### Claim 1

A card tray withdrawing apparatus, arranged to turn on a circuit in a housing and separate a card tray accommodated in the housing from a card slot and comprising: a first interference part arranged at a first position in the housing, a second interference part arranged at a second position in the housing, and a button mounted on the housing, capable of moving from an initial position to the first position and capable of moving from the first position to the second position, wherein the button moving to the first position interferes with the first interference part, and the first interference part turns on the circuit in the housing; and the button moving to the second position interferes with the second interference part, and the second interference part drives the card tray to be separated from the card slot;
wherein the first interference part comprises a first metal arc dome, the first metal arc dome comprises a bottom and an arc top protruding outwards from the bottom, a first wire of the circuit is connected to the top, a second wire of the circuit is connected to the bottom, and the button moving to the first position presses the top to contact with the bottom.

### Claim 2 (depends on 1)

The card tray withdrawing apparatus according to claim 1, wherein the second interference part comprises a moving part movably mounted at the second position in the housing, there is a guide rod extending outwards connected to the moving part in the moving part, and the card tray withdrawing apparatus further comprises a lever arranged in the housing in a rotating manner, one end of the lever is arranged to fit with an outer end of the guide rod, the other end of the lever is arranged to fit with an edge of the card tray, the button moving to the second position interferes with the moving part, the moving part drives the guide rod to move, and the moving guide rod presses the lever to rotate to enable the other end of the lever to pop up the card tray from the card slot.

### Claim 3 (depends on 2)

The card tray withdrawing apparatus according to claim 2, further comprising a mounting groove arranged in the housing, wherein the moving part is arranged in the mounting groove in a sliding manner, the first metal arc dome and the button are both arranged outside the mounting groove, an elastic part is arranged on a bottom wall of the mounting groove, and the button moving to the second position interferes with the moving part to move the moving part towards the bottom wall of the mounting groove, and then the elastic part applies an elastic force to the moving part to rebound the moving part to the second position.

### Claim 4 (depends on 3)

The card tray withdrawing apparatus according to claim 3, wherein the elastic part comprises a second metal arc dome, a bottom of the second metal arc dome is arranged on the bottom wall of the mounting groove, and a top of the second metal arc dome protrudes towards the moving part at the second position.

### Claim 5 (depends on 4)

A communication device, comprising a housing and further comprising the card tray withdrawing apparatus according to claim 4.

### Claim 6 (depends on 3)

A communication device, comprising a housing and further comprising the card tray withdrawing apparatus according to claim 3.

### Claim 7 (depends on 2)

A communication device, comprising a housing and further comprising the card tray withdrawing apparatus according to claim 2.

### Claim 8 (depends on 1)

A communication device, comprising a housing and further comprising the card tray withdrawing apparatus according to claim 1.
