Embodiment 1

[0021] refer to figure 1 , shows a schematic structural view of a card tray loading and unloading device in an embodiment of the present invention. In this embodiment, the card tray loading and unloading device may include: a card tray 1 , a spring 2 and a limiting device 3 .

[0022] In this embodiment, the card tray 1 can be manufactured by powder metallurgy or CNC (Computerized Numerical Control Machine, computer numerical control machine tool) processing. The main difference between the card holder 1 of this embodiment and the existing card holders is that: the card holder 1 of this embodiment is provided with a special guide groove 4 , and the spring 2 can slide in one direction in the guide groove 4 . For example, during the installation and removal process of the card tray 1, the movement of the spring 2 in the guide groove 4 is unidirectional.

[0023] For ease of description, in this embodiment, see Figure 4 , the two ends of the spring 2 can be recorded as: one e...

Embodiment 2

[0032] On the basis of the first embodiment above, this embodiment further details the structure of a card tray loading and unloading device.

[0033] Such as Figure 1 to Figure 4 As shown, in this embodiment, the card tray loading and unloading device may include: a card tray 1 , a spring 2 and a limiting device 3 , and the card tray 1 is provided with a guide groove 4 .

[0034] One end 201 of the spring is connected to the card holder 1 through the guide groove 4 , and the other end 202 of the spring is spaced apart from the first side 101 of the card holder 1 near the guide groove 4 . The limiting device 3 is fixed on the terminal equipment; the limiting device 3 is connected with the spring 2 to fix the spring 2 and limit the lateral and longitudinal displacement of the spring 2 .

[0035] Preferably, in this embodiment, at the third set position of the spring 2, the limit device 3 is connected to the spring 2, so that when the spring 2 is in a free state, the extended ...

Embodiment 3

[0058] In combination with the foregoing embodiments, this embodiment takes the loading and unloading process of the card tray in the mobile terminal as an example to further describe the specific structure of the card tray loading and unloading device in detail. In this embodiment, the device for loading and unloading a card tray is applied in a mobile terminal, that is, the mobile terminal may include the device for loading and unloading a card tray in the foregoing embodiments.

[0059] Cato installation process:

[0060] combined with the above Figure 1-4 , in this embodiment, the Cato installation process may include the following steps:

[0061] Step 12, the user applies an external force F1 to the card tray 1, and the card tray 1 moves in a positive direction (such as +X direction) under the action of the external force F1, wherein one end 201 of the spring moves along the first groove 401 in the card tray 1 slide.

[0062] Step 14, when one end 201 of the spring mo...

Abstract

The invention provides a card holder assembly and disassembly device and a mobile terminal. The card holder assembly and disassembly device comprises a card holder, a spring, and a limiting device. The card holder is provided with a guide slot. One end of the spring is connected with the card holder through the guide slot, and the other end of the spring is spaced from a first side, near the guide slot side, of the card holder. The limiting device is fixed on terminal equipment. The limiting device is connected with the spring to fix the spring and limit horizontal and vertical displacement of the spring. The problem that card holder assembly and disassembly is complex and inconvenient in operation in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a card tray loading and unloading device and a mobile terminal. Background technique [0002] With the rapid development of the electronic communication industry, all kinds of cards are used in portable electronic devices such as mobile phones and tablet computers that we often use in our daily life, such as SIM cards (Subscriber Identity Module, customer Identification module), SD card (Secure Digital Memory Card, secure digital card) for storage, etc. [0003] At present, the SIM card or SD card is usually installed in the electronic device through the card tray. For example, the user puts the SIM card or SD card into the card tray, and then inserts the card tray into the card holder to fix it. However, with the existing installation method, when the tray is taken out, the tray needs to be pushed out by means of a special (metal) thimble or other objects equivalent to th...
