mobile terminal

Abstract

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.

Description

Technical Field

[0001] This invention relates to the field of external card ejection structure technology for communication devices, and more particularly to a mobile terminal. Background Technology

[0002] SIM cards (Subscriber Identity Modules) and memory cards are common cards in mobile terminals. As the structure of mobile terminals becomes more compact, more and more mobile terminals use card trays to install SIM cards and memory cards. In order to facilitate the installation and removal of card trays, mobile terminals need to be equipped with ejection devices. In conventional technology, ejection devices need to reserve a large ejector rod position, which results in the SIM card and its ejection device occupying a large amount of internal space in the electronic device, affecting the stacking space of other components. Summary of the Invention

[0003] This application provides a mobile terminal, the mobile terminal comprising:

[0004] The outer casing has card slot mounting holes;

[0005] The circuit board is disposed inside the housing;

[0006] A card holder is disposed on the circuit board and mates with the circuit board to form a receiving cavity;

[0007] The card holder is movably disposed within the receiving cavity and can be inserted into or removed from the receiving cavity through the card holder mounting hole; at least one of the card holder and the housing is provided with an ejection hole.

[0008] A toggle mechanism is provided, which has a pivot shaft on the outer side of the projection of the card tray in the direction of movement. The pivot shaft can be connected to the outer shell or the card holder. One end of the toggle mechanism is a pin action end, and the other end is a card tray ejection end. The pin action end and the card tray ejection end move in opposite directions. When the pin applies force to the pin action end through the ejection hole, the pin action end moves into the outer shell, and the card tray ejection end pushes the card tray away from the outer shell, thereby realizing the ejection of the card tray.

[0009] The mobile terminal provided in this application embodiment has its pivot installed on the outside of the projection of the card tray in the direction of movement, which reduces the length of the card tray in the direction of movement and the width in the direction of non-movement, making it more conducive to the overall stacking layout inside the mobile terminal. At the same time, it is also more convenient to process and install, and it is invisible and saves costs. Meanwhile, the toggle mechanism is not installed in the narrow space of the circuit board, so the structural space is relatively good, which is more conducive to the design and implementation of a reliable and durable structure.

[0032] Please refer to the following: Figures 1 to 7 , Figure 1 This is a schematic diagram illustrating the usage status of the mobile terminal SIM card tray in this application. Figure 2 This is a structural breakdown diagram of an embodiment of the mobile terminal of this application. Figure 3 This is a partial structural schematic diagram of an embodiment of the mobile terminal dialing mechanism as a lever mechanism in this application. Figure 4 yes Figure 3 A magnified view of a portion at point A in the embodiment. Figure 5 This is a partial structural diagram of another embodiment of the mobile terminal dialing mechanism in this application, which is a lever mechanism. Figure 6 yes Figure 5 A magnified view of a portion at point B in the embodiment. Figure 7 yes Figure 6A structural schematic diagram from another perspective in the embodiment; wherein, the mobile terminal 1 includes a housing 10 with a card tray mounting hole 101; a circuit board 20 disposed inside the housing 10; a card holder 30 disposed on the circuit board 20 and cooperating with the circuit board 20 to form a receiving cavity; a card tray 40 movably disposed in the receiving cavity and can be inserted into or removed from the receiving cavity through the card tray mounting hole 101, at least one of the card tray 40 and the housing 10 having an ejection hole; a toggle mechanism 50, the toggle mechanism 50 being provided with a pivot shaft 501, the pivot shaft... 501 is located on the outer side of the projection of the card tray 40 in the direction of movement. The pivot shaft 501 can be connected to the housing 10 or the card holder 30. One end of the actuating mechanism 50 is the ejector pin end 502, and the other end is the card tray ejection end 503. The ejector pin end 502 and the card tray ejection end 503 move in opposite directions. When the ejector pin applies force to the ejector pin end 502 through the ejection hole, the ejector pin end 502 moves into the housing 10. The card tray ejection end 503 pushes the card tray 40 to move away from the housing 10, thereby realizing the ejection of the card tray 40.

[0033] The mobile terminal 1 provided in this application embodiment has a pivot shaft 501 of its toggle mechanism 50 mounted on the outer side of the projection of the card tray 40 in the direction of movement, so that the card tray 40 in the direction of movement (e.g. Figure 3 The length decreases in the Y-Y direction, and in the inactive direction (e.g.) Figure 3 The reduced width (in the X-X direction) facilitates the overall stacking layout inside the mobile terminal 1, while also making processing and installation more convenient, concealed, and cost-effective. Furthermore, the toggle mechanism 50 is not installed in the narrow space of the circuit board 20, resulting in relatively better structural space and making it easier to design and implement a reliable and durable structure.

[0034] The mobile terminal 1 provided in this application embodiment has a pivot shaft 501 of its toggle mechanism 50 mounted on the outer side of the projection of the card tray 40 in the direction of movement, so that the card tray 40 in the direction of movement (e.g. Figure 3 The length of the card holder 40 in the Y-Y direction can be reduced by 2.4 to 2.6 mm, optionally by 2.5 mm, or optionally by 2.43 mm; while simultaneously allowing the card holder 40 to be used in the non-active direction (e.g., Figure 3 The width in the X-X direction can be reduced by 1.3 to 1.4 mm, and optionally by 1.35 mm; this reduces the space occupied by the card tray 40 and is more conducive to the stacking layout inside the mobile terminal 1.

[0035] Optionally, please refer to the following as well. Figure 4 and Figure 6Optionally, the actuating mechanism 50 in this embodiment can be a lever mechanism; the ejector pin end 502 is the power arm of the lever mechanism, the card holder ejection end 503 is the resistance arm of the lever mechanism, and the pivot shaft 501 is the fulcrum of the lever mechanism; the ejector pin end 502 and the card holder ejection end 503 can rotate around the pivot shaft 501. When the ejector pin end 502 is subjected to force by the ejector pin, the card holder ejection end 503 pushes the card holder 40 around the pivot shaft 501, causing the card holder 40 to move away from the outer shell 10, thereby realizing the ejection of the card holder 40.

[0036] The mobile terminal 1 provided in this application embodiment has a lever mechanism 50, which is simple in structure and occupies little internal space in the mobile terminal 1. At the same time, the length of the pin action end 502 and / or the card holder ejection end 503 can be designed as needed, so that the applied force and the movement range of the card holder ejection end 503 can be changed as needed.

[0037] Please continue reading. Figure 7 Optionally, the card tray 40 may be provided with an ejection portion 401. The ejection portion 401 provides a force point for the ejection end 503 of the card tray. The ejection portion 401 is located at one end of the card tray 40 near the outer shell 10, and the ejection portion 401 faces the inside of the outer shell 10. It is located at either end of the two ends perpendicular to the sliding direction of the card tray 40, as long as the ejection portion 401 corresponds to the position of the ejection end 503 of the toggle mechanism 50. No specific limitation is made here. When the card tray 40 is ejected from the outer shell 10, the ejection end 503 of the card tray pushes the ejection portion 401, thereby realizing the ejection of the card tray 40.

[0038] The mobile terminal 1 provided in this application embodiment has a card tray ejection portion 401 that reduces the length of the card tray ejection end 503. This ensures that the function of the toggle mechanism 50 ejecting the card tray 40 is maintained while the size is smaller, thereby reducing the space occupied by the toggle mechanism 50 inside the mobile terminal 1.

Figure 17 yes Figure 16 A partial enlarged view at point F in the embodiment; Optionally, the actuating mechanism 50 in this embodiment can be a belt conveyor mechanism, with the ejector pin end 502 and the card tray ejector end 503 connected by a transmission belt 504. One end of the transmission belt 504 is connected to the ejector pin end 502, and the other end is connected to the card tray ejector end 503. The transmission belt 504 partially surrounds the pivot shaft 501. When the ejector pin end 502 is subjected to force by the ejector pin, the card tray ejector end 503 is driven by the transmission belt 504 to push the card tray 40, causing the card tray 40 to move away from the outer shell 10, thereby realizing the ejection of the card tray 40.

[0040] The mobile terminal 1 provided in this application embodiment has a toggle mechanism 50 that can be a belt conveyor mechanism. The belt conveyor mechanism has a simple structure and occupies little internal space in the mobile terminal 1. The belt conveyor mechanism operates smoothly and reliably, can mitigate impacts and absorb vibrations, making the toggle mechanism 50 less prone to damage and improving the service life of the toggle mechanism 50.

Outside the groove 50221, the limiting block 50222 and the conveyor belt 504 are prevented from sliding out of the connecting part 5022, ensuring effective connection between the ejector pin action end 502 and the conveyor belt 504; the card tray ejection end 503 may include an ejector rod 5031 and a linkage part 5032; the ejector rod 5031 is used to eject the card tray 40; the linkage part 5032 is fixedly connected to the other end of the conveyor belt 504; when the action part 5021 is subjected to the force applied by the ejector pin, the end of the conveyor belt 504 connected to the ejector pin action end 502 can move into the housing 10 under the drive of the connecting part 5022, and the linkage part 5032, under the drive of the conveyor belt 504, drives the ejector rod 5031 to move in a direction away from the inside of the housing 10, thereby realizing the ejection of the card tray 40 by the ejector rod 5031.

The conveyor belt 504 is inserted into the hole of the support member 50322 through the through hole 50321 of the linkage part 5032, thereby realizing the connection between the card tray ejection end 503 and the conveyor belt 504. The baffle 50323... 23 prevents the top holding member 50322 and the conveyor belt 504 from sliding out of the linkage part 5032, ensuring effective connection between the card tray ejection end 503 and the conveyor belt 504; when the action part 5021 of the ejector pin action end 502 is subjected to the force applied by the ejector pin, the end of the conveyor belt 504 connected to the ejector pin action end 502 can move into the housing 10 under the drive of the ejector pin action end 502 connection part 5022.

[0043] Alternatively, please continue reading Figure 15 and Figure 17 A spring 5033 may be fitted onto the card holder ejection end 503. The spring 5033 is used to reset the card holder ejection end 503 towards the inside of the housing 10 when the push is removed, so that the card holder ejection end 503 retracts into the housing 10, thereby realizing the reset of the entire toggle mechanism 50.

This reduces the length of the card tray 40 in the direction of movement and the width in the direction of non-movement, which is more conducive to the overall stacking layout inside the mobile terminal 1. At the same time, it is easier to process and install, and it is also more concealed and cost-effective.
