Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

The terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific sequence or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances such that the embodiments of the application can be practiced in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of the connected objects, and the character "/" generally means that the related objects are an "or" relationship.

The electronic device provided by the embodiments of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

Please refer to FIG. 1 to FIG. 7 , the embodiment of the present application discloses an electronic device, and the disclosed electronic device includes a card tray assembly, a movable part 121 and a trigger part 130 .

The card tray assembly includes a card holder 110 and a card holder 120, and the card holder 110 provides an installation basis for the components of the card tray assembly. The card base 110 defines a receiving groove 111 , and the card holder 120 is detachably disposed in the receiving groove 111 , and the receiving groove 111 is used for installing the card holder 120 at this time. The card tray 120 is used to carry an electronic card, and the electronic card may be a Subscriber Identification Module (SIM) card or a memory (Trans-flash, TF) card.

The movable part 121 is disposed around the card holder 120 and is movably connected with the card holder 120 . At this time, when the card tray 120 is installed in the receiving groove 111 , at least part of the card tray 120 and at least part of the movable part 121 are located in the receiving groove 111 .

The trigger 130 is disposed in the receiving groove 111 , and the trigger 130 is electrically connected to the circuit board of the electronic device.

When the card tray 120 is located in the receiving slot 111 , the movable part 121 can press the key trigger part 130 to trigger a preset function of the electronic device.

In a specific operation process, when the user needs to install the card tray 120 into the receiving groove 111 , the user puts the card tray 120 into the receiving groove 111 from the notch of the receiving groove 111 . When the preset function needs to be realized, the user applies force to the movable part 121 to drive the movable part 121 to move until the trigger part 130 is pressed. When the trigger part 130 receives the pressing signal, it transmits the pressing signal to the circuit board of the electronic device , the circuit board responds to the pressing signal to output corresponding control functions. For example, the preset function may be to control functions of the electronic device such as volume adjustment, muting, taking pictures, and invoking a voice assistant.

In the embodiments disclosed in this application, the movable part 121 presses the trigger part 130 to realize the preset function of the electronic device. At this time, the card tray assembly can integrate key functions, thereby reducing the number of openings on the surface of the casing, and there is no need to reserve an installation space for the key module in the electronic device, thereby saving space for the installation of other devices.

In addition, the casing of the electronic device in the background art needs to be provided with installation holes for the card holder assembly and the button module. The large number of openings in the casing also makes the waterproof and dustproof performance of the electronic equipment poor.

In the embodiments disclosed in the present application, the card tray assembly can integrate the button function, so the electronic device does not need to be additionally equipped with a button module, and therefore there is no need to open an installation hole for installing the button module on the housing. Therefore, the number of openings in the casing of the electronic device is reduced, and the appearance consistency of the electronic device is improved. At the same time, the number of openings in the casing is small, and the waterproof and dustproof performance of the electronic device is also improved.

In addition, since the key function is integrated into the card support component, there is no need to set a key module in the electronic device, thereby simplifying the composition structure of the electronic device, optimizing the layout of the electronic device, and reducing the manufacturing cost of the electronic device.

Optionally, the direction of the force applied by the user to the movable part 121 may be the direction from the notch of the receiving groove 111 to the bottom of the groove, that is to say, the user presses the movable part 121 . The direction of the force applied by the user to the movable part 121 may be parallel to the plane where the notch is located, that is to say, the user pushes the movable part 121 along the outer surface of the casing.

In the above embodiment, when the movable part 121 does not press the trigger part 130, the trigger part 130 is not grounded at this time, and the pressing signal received by the circuit board is at a high level. When the movable part 121 presses the trigger part 130, the trigger part 130 is grounded, so the trigger part 130 divides the voltage to a low voltage, and the pressing signal received by the circuit board is at a low level, so the button function is activated. Certainly, the pressing signal received by the circuit board may also be a signal in other forms, which is not limited herein.

When the card holder 120 is located in the receiving groove 111 , the card holder 120 is limitedly matched with the limiting portion 112 to limit the movement of the card holder 120 in the receiving groove 111 .

At this time, when the card tray 120 is assembled to the specified position, the stopper 112 restricts the movement of the card tray 120 in the receiving groove 111, thereby preventing the card tray from moving when the user presses the movable part 121, thereby preventing the electronic card from being released from the card. The bracket 120 falls off to ensure the safety and reliability of the electronic equipment.

In another optional embodiment, the electronic device disclosed in the present application may further include a first elastic member 140, the first elastic member 140 may be located in the receiving groove 111, and one end of the first elastic member 140 is connected to the trigger member 130. The other end of the first elastic member 140 is connected to the movable member 121 in transmission. At this time, when the movable member 121 does not move relative to the card holder 120 , the end of the first elastic member 140 facing the movable member 121 may have a certain gap with the movable member 121 , or may abut against the movable member 121 .

In the specific operation process, when the user applies force to the movable part 121, the movable part 121 compresses the first elastic part 140, the first elastic part 140 is compressed and undergoes elastic deformation, and the first elastic part 140 transmits the applied force to the The trigger 130, the trigger 130 generates a pressing signal. When the user removes the force on the movable part 121, the first elastic part 140 resumes its elastic deformation, thereby driving the movable part 121 to an initial position, thereby facilitating the next operation of the movable part 121. The initial position refers to the position where the movable part 121 does not press the trigger part 130 .

In this solution, the first elastic member 140 can play a role in resetting the movable member 121 , thereby facilitating the operation of the movable member 121 . In addition, since the trigger member 130 is elastically connected to the movable member 121 through the first elastic member 140 , the first elastic member 140 can also play a buffering role, preventing the trigger member 130 from being damaged due to rigid contact with the movable member 121 .
