Embodiment 1

[0087] Such as figure 1 As shown, this embodiment discloses a card tray locking device 10 and a mobile terminal 1 including the card tray locking device 10 .

[0088] The card tray locking device 10 includes: a housing 100 , a card seat 200 , a card tray 300 , a limiting component 400 and an elastic component 500 .

[0089] The card holder 200 is disposed on the casing 100 , and the card holder 300 is disposed in the card holder 200 , and a first limiting portion 310 is disposed on one side of the card holder 300 . The limiting part 400 has a second limiting part 410, and the limiting part 400 can move in a direction different from the moving direction of the card holder 300 to change between a locked state and an unlocked state; in the locked state , the second limiting portion 410 is in contact with the first limiting portion 310 to limit the ejection of the card tray 300 (with figure 1 As an example, the movement of Cato 300 to the left is ejection). The elastic member 5...

Embodiment 2

[0093] Such as Figure 2-11 As shown, this embodiment discloses a card tray locking device 10 and a mobile terminal 1 including the card tray locking device 10 .

[0094] combine Figure 2-5 , The card tray locking device 10 includes: a housing 100 , a card holder 200 , a card tray 300 , a limiting component 400 , an elastic component 500 and a PCB (Printed circuit board, printed circuit board) 600 . figure 2 main view, Figure 4 It is a rear view. In this embodiment, the housing 100 is in front, so figure 2 The housing 100 is not shown in order to avoid its covering other structures; the PCB board 600 is behind, so Figure 4 The PCB board 600 is not shown in order to avoid its obscuring other structures. The card holder 200 is fixed on the PCB board 600 and then installed in the casing 100 , and the card holder 300 is arranged in the card holder 200 . Such as Figure 2-4 As shown, one side of the card tray 300 is provided with a first limiting portion 310 . The limit...

Abstract

The invention discloses a card tray locking device and a mobile terminal containing the same. The card tray locking device comprises a shell, a card base and a card tray, wherein a first limit part isarranged on one side of the card tray. Furthermore, the card tray locking device further comprises a limit component and an elastic component, wherein the limit component is provided with a second limit part, and the limit component can move in the directions different from the moving direction of the card tray to change between a locking state and an unlocking state; under the locking state, thesecond limit part and the first limit part are in contact to limit the card tray to be popped out; the elastic component acts on the second limit part and can transmit change force between the secondlimit part and the shell, and the elastic component is used for making the second limit part move from the unlocking state to the locking state. By means of interaction between the first limit part and the second limit part, the card tray is locked, and a displacement probability of the card tray is reduced; the elastic component is favorable for the second limit part to be switched between the unlocking state and the locking state; convenience in operation is achieved.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a card tray locking device and a mobile terminal including the same. Background technique [0002] In the prior art, in a mobile terminal such as a mobile phone, the card holder (including the SIM card holder, the T card holder or the combination of the SIM card holder and the T card holder) is generally arranged in the card holder, and the card holder is fixed on the PCB board and then Set on the shell (face shell or back shell). [0003] However, during the drop or roll test of the mobile terminal, there will be relatively large vibrations, and the card tray is easily displaced and ejected from the card holder. Most of the technical means adopted to solve this problem at present are: increasing the clamping force of the Cato. But because in the normal unlocking process, the clamping force of the clamping force of the clamping force of the clamping force must be overc...
