When the card holder is removed from the mobile device, the SIM card may be directly ejected from the accommodating cavity due to the lack of a limiting structure.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a SIM card holder with a self-ejecting function comprises a SIM card holder body, the inner wall on the right side of the SIM card holder body is provided with an ejection structure for ejecting the upper end surface of the SIM card, and the interior of the lower side of the SIM card holder body is provided with a limiting structure for limiting the bottom of the SIM card.

[0007] The ejection structure includes a protection block fixedly connected to the right side of the inner wall of the SIM card holder body, a first small telescopic rod fixedly connected to the inner top wall of the protection block, a first spring fixedly sleeved on the outside of the first small telescopic rod, and a SIM card frame fixedly connected to the end of the first small telescopic rod away from the protection block.

[0008] The limiting structure includes two second small telescopic rods fixedly connected to the bottom of the inner side of the SIM card holder body, a second spring fixedly sleeved on the outside of the two second small telescopic rods, and a stopper fixedly connected to one end of the second small telescopic rod.

[0009] Furthermore, a resistance component for resisting the upper side of the SIM card is arranged at the top of the SIM card holder body, and the resistance component includes two limit top plates fixedly connected to the left side of the inner wall of the SIM card holder body, and the two limit top plates are arranged vertically.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3In this embodiment, a SIM card holder with a self-elastic function comprises a SIM card holder body 1, an inner wall on the right side of the SIM card holder body 1 is provided with an ejection structure for ejecting the upper end surface of the SIM card, and a limiting structure is provided inside the lower side of the SIM card holder body 1 for limiting the bottom of the SIM card. The ejection structure comprises a protection block 5 fixedly connected to the right side of the inner wall of the SIM card holder body 1, a first small telescopic rod 6 fixedly connected to the inner top wall of the protection block 5, a first spring 7 fixedly sleeved on the outside of the first small telescopic rod 6, and a SIM card frame 8 fixedly connected to the end of the first small telescopic rod 6 away from the protection block 5. The limiting structure comprises two second small telescopic rods 12 fixedly connected to the bottom of the inner side of the SIM card holder body 1, a second spring 13 fixedly sleeved on the outside of the two second small telescopic rods 12, and a stopper 14 fixedly connected to one end of the second small telescopic rod 12.

[0024] Among them, a resistance component for resisting the upper side of the SIM card is arranged at the top of the SIM card holder body 1, and the resistance component includes two limit top plates 3 fixedly connected to the left side of the inner wall of the SIM card holder body 1, and the two limit top plates 3 are arranged vertically. The inner bottom wall of the SIM card holder body 1 is provided with a conductive component for conducting electricity to the SIM card, and the conductive component includes a plurality of conductive terminals 4 fixedly connected to the inner bottom wall of the SIM card holder body 1 and a plurality of limit top plates 3 opened on the inner bottom wall of the SIM card holder body 1. The plurality of conductive terminals 4 are clamped in the inner limit top plates 3, and a limit groove 17 is opened on the upper side of the protection block 5. A first through hole 10 is provided on the left side of the protection block 5, and a vertical rod 9 is fixedly connected to the upper end of the SIM card frame 8 near the first small telescopic rod 6. The upper side of the vertical rod 9 passes through the limiting groove 17 and extends to the outside, and a pull rod 15 is fixedly connected to the lower side of the second small telescopic rod 12. The left and right ends of the lower side of the SIM card holder body 1 are rotatably connected to the baffle 16. The left and right ends of the lower side of the SIM card holder body 1 are provided with grooves 11, and one end of the second small telescopic rod 12 away from the baffle 14 is fixedly connected to the inner wall of the groove 11, and the opposite side of the SIM card holder body 1 away from the baffle 16 is fixedly connected to the card plate 2.

[0025] It should be noted that two limiting top plates 3 are arranged on a side surface of the top of the SIM card holder body 1. When the SIM card is inserted into the upper side of the SIM card holder body 1, the lower side of the limiting top plate 3 can contact the upper side of the SIM card, thereby effectively preventing the SIM card from moving out of the upper side of the SIM card holder body 1. When the SIM card frame 8 moves under the action of the first small telescopic rod 6 and the first spring 7, the vertical rod 9 slides in the limiting groove 17 opened on the upper side of the protective block 5, thereby playing a limiting role, so that the SIM card frame 8 can be more stable when moving. The retractable structure of the pull rod 15 itself can be compressed between the baffle 16 and the second small telescopic rod 12 when not in use, thereby reducing its own size.

[0026] The working principle of the above embodiment is:

[0027] Insert the SIM card from the lower side end of the SIM card holder body 1 into the interior. When the SIM card moves between the two blocks 14, the second small telescopic rod 12 cooperates with the second spring 13 to compress and deform to change the position of the block 14 and move it into the groove 11. After one end of the SIM card contacts the lower side of the SIM card frame 8, the thrust generated by the finger compresses the first small telescopic rod 6 and the first spring 7 and continues to move the SIM card into the SIM card holder body 1. When the SIM card is completely moved into the SIM card holder body 1, the block 14 at the bottom of the SIM card holder body 1 will be moved out by the rebound force of the second spring 13, and the first spring 7 pushes the SIM card on one side of the SIM card frame 8 downward through the rebound force to cooperate with the block 14 to achieve the up and down movement of the SIM card. The two sides are in contact with each other, and at the same time, the upper end of the SIM card is limited by the limiting top plate 3. The bottom of the SIM card contacts the conductive terminal 4 and the card plate 2 is held to insert the SIM card holder body 1 into the mobile device for operation. When the SIM card needs to be removed, just pull the baffle 16 to rotate and separate from the bottom of the SIM card holder body 1, and pull the pull rod 15 to extend outward. The fingers respectively contact the opposite surfaces of the two pull rods 15 and apply pressure at the same time. The block 14 will be compressed again by the second small telescopic rod 12 and the second spring 13 under the action of the pull rod 15 and move into the groove 11. At this time, there is no contact limit of the block 14 on the lower side of the SIM card, and the SIM card can be directly ejected by applying pressure to the SIM card frame 8 through the rebound force of the first spring 7.
