Detailed Description

In the description of the present invention, it is to be understood that the terms "upper", "lower", "left", "right", "front", "rear", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

The contents of the present invention will be further described in detail with reference to the specific embodiments, and fig. 1 and fig. 2 respectively show the three-dimensional schematic diagrams of the SIM card seat in two different states, which is mainly composed of the card holder 1, the outer shell 2, the unlocking mechanism 3, and so on. The card holder 1 is inserted into the outer case 2 along the right-to-left direction, and has a receiving groove 11 for receiving the SIM card. The front and rear side walls of the card holder 1 are respectively provided with a front limit notch 12 and a rear limit notch 13, and correspondingly, a front limit elastic sheet 21 matched with the front limit notch 12 and a rear limit elastic sheet 22 matched with the rear limit notch 13 extend from the front and rear side walls of the outer shell 2. The unlocking mechanism 3 comprises a push rod 31, a hinge shaft 32, a rotary swing arm 33 and a left elastic pushing sheet 341. The push rod 31 is disposed in the inner cavity of the outer case 2 and can slide in the left-right direction. The push rod 31 is arranged in parallel at the front side of the preset position of the card holder 1. The rotary swing arm 33 is hinged in the cavity of the outer shell 2 by a hinge shaft 32, and the front swing end of the rotary swing arm is opposite to the left side wall of the card holder 1, and the rear swing end of the rotary swing arm is inserted into the push rod 31. As shown in fig. 5, the left-hand elastic pushing piece 341 is drawn directly rightward from the left side wall of the outer case 2, and is disposed right to the left of the hinge shaft 32. When the SIM card is in the locked state, the left elastic pushing piece 341 and the rotating swing arm 33 are maintained in the critical contact state (as shown in fig. 3, 4, 5, 6, 7, 8). In this way, in the process that the rotating swing arm 33 performs the rotating motion to unlock the card holder 1, the left elastic pushing plate 341 always applies the elastic pushing force to the left sidewall thereof, so as to offset a part of the lateral force applied to the hinge shaft 32, thereby reducing the probability of the hinge shaft 32 being damaged, and ensuring that the SIM card still has a good unlocking function within a relatively long period of time.

The working principle of the SIM card holder is as follows: as shown in fig. 9 and 10, when the loading operation of the card holder 1 is performed, the card holder 1 slides in the right-to-left direction under the action of the pushing force, and at the same time, the front position-limiting elastic piece 21 and the rear position-limiting elastic piece 22 slide along the front side wall and the rear side wall of the card holder 1 respectively until the front position-limiting elastic piece 21 and the rear position-limiting elastic piece 22 automatically snap into the front position-limiting notch 12 and the rear position-limiting notch 13, at this time, the left side wall of the card holder 1 pushes the front swing end 331 of the rotating swing arm 33 to perform counterclockwise rotation, and the push rod 31 slides in the left-to-right direction under the action of the driving force of the rear swing end 332 of the rotating swing arm 33. When the card holder 1 is withdrawn (i.e. the SIM card is taken out), the hand-held card pushes the right end of the push rod 31 to drive the front swing end of the rotary swing arm 33 to perform clockwise returning rotary motion, and at the same time, the rear swing end 332 of the rotary swing arm 33 applies a right pushing force to the left side wall of the card holder 1 until the front limiting elastic sheet 21 and the rear limiting elastic sheet 22 are completely separated from the front limiting notch 12 and the rear limiting notch 13, respectively, thereby realizing the unlocking operation of the card holder 1. In the process that the rotating swing arm 33 is pushed by the push rod 31, the left elastic pushing plate 341 always applies a certain elastic pushing force to the left sidewall of the rotating swing arm 33, thereby effectively sharing the lateral force applied to the hinge shaft 32.

Of course, other structure forms of the limiting portion 34 may be adopted to elastically push the rotating swing arm 33, such as: a limit boss (not shown in the figure) formed by extending upwards from the bottom wall of the inner cavity of the outer shell 2. It should be noted that, during the forming process, the cross-sectional dimension of the limiting boss needs to be strictly controlled to ensure that the limiting boss has a certain elastic capability, so as to ensure that the rotating swing arm 33 always receives a lateral propping force in the rotating process.

As can be seen from fig. 2, a slot extends downwardly from the top wall of the push rod 31 a predetermined distance from the left end face thereof for fitting the front swing end of the rotary swing arm 33. In the process of locking and unlocking the card holder 1, the front swing end 331 of the rotary swing arm 33 always slides along the slot. In view of this, as shown in fig. 1, 5, 6, and 7, a stopper groove 311 extends downward from the top wall of the push rod 31 at a predetermined distance from the right end surface. The outer casing 2 is provided with a fracture notch to form a limit spring 23 matched with the limit groove 311. Therefore, after the card holder 1 is locked, the limiting elastic sheet 23 is just arranged in the limiting groove 311 to prevent the push rod 31 from moving along the left-right direction, so that abnormal sound of SIM card holder application equipment caused by shaking is avoided, and finally, a user is ensured to have good use experience.

As shown in fig. 1, 2 and 6, as a further optimization of the structure of the SIM card socket, the push rod 31 thereof may also be subjected to a bending process to form an external bending bearing section 312 at the right end thereof. Therefore, the top applying area of the clamping needle is effectively enlarged, and the requirement on the alignment precision of the clamping needle and the push rod 31 in the card withdrawing operation is further relaxed.

Finally, it should be noted that, as shown in fig. 7, anti-slip dimples 3121 may also be provided on the folded-out force-bearing section 312. The anti-slip dimple 3121 is formed by extending the right sidewall of the outer folding bearing section 312 to the left. The anti-slip pits 3121 can effectively prevent the needle from slipping during the pushing process of the pushing rod 31, and ensure the stability of the pushing force.
