For better understanding of the present application, the electronic device provided in the embodiment of the present application is described below with reference to fig. 1 to 13. The electronic device provided by the embodiment of the application is, for example, a smart phone, a tablet computer, a notebook computer, a smart wearable device, and other electronic products of various types, which is not limited in the application.

According to an embodiment of the present application, referring to fig. 1 to 4, an electronic device includes: a housing 1, a card holder 2, a guide rail assembly 3 and a screen 4. In the embodiment of the present application, the rail assembly 3 and the shutter 4 are provided specifically for the card holder 2, and facilitate the removal of the card holder 2 from the housing 1.

Wherein, the housing 1 is provided with a receiving groove 11 for receiving the card holder 2. The card support 2 is movably arranged in the accommodating groove 11, and the card support 2 is connected with an ejection mechanism 21. That is, in the embodiment of the present application, the card holder 2 is designed to be movable, and the card holder 2 can be installed in the receiving groove 11 or the card holder 2 can be taken out from the receiving groove 11. When the card holder 2 is taken out, the card holder 2 can be ejected from the accommodating groove 11 by the ejection mechanism 21 through the ejection mechanism 21 connected to the card holder 2.

The rail assembly 3 and the shutter 4 are also disposed in the receiving groove 11 of the housing 1. Referring to fig. 4 to 6, the guide rail assembly 3 may include a first guide rail 31 and a second guide rail 32, wherein one end of the first guide rail 31 forms a stopper 311.

In an embodiment of the present application, the shutter 4 is switchable between a first state and a second state;

in the first state, referring to fig. 7 to 9, the shutter 4 is used for pressing the card holder 2 to receive the card holder 2 in the receiving slot 11, the card holder 2 elastically supports the shutter 4 through the eject mechanism 21, so that the shutter 4 forms a sliding fit with the second guide rail 32, and the stopping portion 311 of the first guide rail 31 is used for stopping the shutter 4;

In the overall design, the shutter 4, and the ejection mechanism 21 connected to the card holder 2, play an important role in freely switching between these two states of the card holder 2.

Wherein the shielding piece 4 is located at the notch of the accommodating groove 11, and the shielding piece 4 can slide on the notch of the accommodating groove 11. When the card holder 2 is accommodated in the accommodating groove 11, the shielding member 4 can stay on the notch of the accommodating groove 11 and is located at a position corresponding to the card holder 2 in the accommodating groove 11, so that the card holder 2 can be completely pressed, and the card holder 2 can be stably limited in the accommodating groove 11. When the card holder 2 needs to be taken out, the shielding piece 4 can slide to another position on the notch of the accommodating groove 11, and the position can avoid the card holder 2, namely, the card holder 2 is not pressed and shielded, so that enough space is reserved for the ejection of the card holder 2, and the card holder 2 can be ejected out of the accommodating groove 11 smoothly without being pressed by the shielding piece 4, thereby being convenient for taking out the card holder 2.

Wherein the ejection mechanism 21 is connected to the card holder 2. The ejecting mechanism 2 has different functions between a state where the card tray 2 is accommodated in the accommodating groove 11 and a state where the card tray is ejected out of the accommodating groove 11. When the card holder 2 is accommodated in the accommodating groove 11, the shutter 4 is in a first state, that is, the shutter 4 presses the card holder 2 at the position of the notch of the accommodating groove 11, and at this time, the function of the ejecting mechanism 21 is to provide a certain ejecting force to the shutter 4, so that the shutter 4 is kept at a position where it can be stopped by the stopping portion 311 of the first guide rail 31, and the shutter 4 can stay at a position where it can press the card holder 2 without any slippage. When the card holder 2 needs to be ejected out of the receiving slot 11, the shutter 4 can be slid to another position, the shutter 4 is in the second state, and the position does not press the card holder 2, and the ejecting mechanism 21 is configured to provide a force for ejecting the card holder 2 from the receiving slot 11, so that the card holder 2 can be ejected.
