Description

Technical Field

[0001] This utility model relates to the field of SIM card tray technology, and in particular to a card tray structure that facilitates card removal. Background Technology

[0002] A SIM card, also known as a smart card, is a small integrated circuit card embedded in a mobile phone, primarily used in GSM and other types of mobile phone networks. The SIM card stores the user's identification information, which is used to uniquely identify the user within the network and allow the user to access the network for calls, text messages, or data services. The SIM card tray, also called a SIM card holder or SIM card slot, is a component in mobile devices used to hold and secure the SIM card; it is usually located on the side of the device. Existing SIM card tray structures can generally meet daily usage needs, but due to their basic structure, removing the card requires force to pull it back, and the internal spring contacts require considerable pulling force, affecting the convenience of card removal. Furthermore, most existing tray structures are one-piece molded structures, making it difficult to adjust when the internal spring contacts deform, impacting the product's practicality. Therefore, designing a SIM card tray structure that facilitates easy card removal is essential. Utility Model Content

[0003] The purpose of this utility model is to provide a card tray structure that facilitates card removal, in order to solve the problems of existing card tray structures being limited by the basic framework of the card tray, requiring force to pull back when removing the card, and requiring a large pulling force under the pressure of the internal spring, which affects the convenience of card removal; at the same time, most existing card tray structures are one-piece molded structures, and it is difficult to adjust when the internal spring deforms, which affects the practicality of the product.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a card holder structure for easy card ejection, comprising a bottom support, a first spring, a second spring, a push rod, a pressing element, a hook groove, a limiting element, a toggle block, a support column, a locking head, a square hole, and a top cover. The bottom support is fitted with a first connecting piece and a second connecting piece, and the first connecting piece and the second connecting piece are respectively provided with a first spring and a second spring. A limiting block is provided on one side of the top of the bottom support, and a push rod is slidably connected between the limiting block and the bottom support. A pressing element is provided at one end of the push rod, and a hook groove is provided at the other end of the push rod. The hook groove is fitted with one end of the toggle block, and a support column is rotatably connected in a through hole opened at the center of the toggle block. The support column is fixed to the top of the bottom support. A locking head is provided at the top of the other end of the toggle block, and the locking head is fitted into the square hole, which is opened on the top cover.

[0005] As a further technical solution of this utility model, the first connecting piece and the second connecting piece are both electrically connected to the connecting base plate, and the connecting base plate is fixed to the bottom of the bottom support.

[0006] As a further technical solution of this utility model, a limiting member is provided at the end of the push rod near the hook groove.

[0007] As a further technical solution of this utility model, the top cover is provided with side plates on both sides, and the side plates are provided with first slots on both sides.

[0008] As a further technical solution of this utility model, a first card block is connected in the first bayonet slot, and the first card block is symmetrically arranged on the bottom support.

[0009] As a further technical solution of this utility model, a second locking block is symmetrically arranged on the bottom support, and the second locking block is engaged in the second locking slot. The second locking slot is opened on the tail plate, and the tail plate is fixed on the top cover.

[0010] As a further technical solution of this utility model, mounting plates are symmetrically arranged on both sides of the bottom of the bottom support, and a connecting column is provided on the top of the mounting plate.

[0011] This utility model provides a convenient card tray structure for SIM card ejection. Its advantages include: a limiting block on one side of the bottom support limits the push rod, while a rotating actuating block connected to the support column matches one end of the push rod via a hook groove. During SIM card insertion, the actuating block is pressed against it, locking the top of the actuating block against the square hole. When ejecting the card, a pressing component pushes the push rod into the card tray, and the hook groove pushes the actuating block around the support column to eject the SIM card. This operation is easy and improves the convenience of card ejection. Furthermore, the cooperation between the first slot and the first card block, and the second card block and the second slot, allows the top cover to be secured to the top of the bottom support, facilitating the removal of the top cover for adjustment of the first and second springs, thus improving the product's practicality.
