This application provides a mobile terminal, comprising a housing, a circuit board, a card holder, a card tray, and a toggle mechanism. The housing has a card tray mounting hole. The circuit board is located inside the housing, and the card holder is located on the circuit board, forming a receiving cavity. The card tray is movably disposed within the receiving cavity and is inserted into or removed from the cavity through the card tray mounting hole. At least one of the card tray and the housing has an ejection hole. The toggle mechanism has a pivot shaft, which is located outside the projection of the card tray in the direction of movement and connected to the housing or the card holder. The two ends of the toggle mechanism are a pin action end and a card tray ejection end, with opposite directions of movement. When the pin applies force to the pin action end, the pin action end moves inward into the housing, and the card tray ejection end pushes the card tray away from the housing, thus ejecting the card tray. This mobile terminal reduces the size of the card tray structure, facilitating the overall internal layout of the mobile terminal, simplifying manufacturing and installation, and saving costs. The toggle mechanism has better installation space, which is beneficial for designing and implementing a reliable and durable structure.
