Detailed Description

To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.

Referring to fig. 15, in the present application, a of the SIM card 60 is long, and B is wide.

Referring to fig. 1 to 15, the present application discloses a card chamber structure of a SIM card, including: the device comprises an elastic device 11, an SIM card sliding block 12, a card cabin body 13, a limiting mechanism 14 and a front cover 15; a first cavity 16 for accommodating an SIM card 60 is formed in the card chamber body 13, an opening 17 is formed at one end of the card chamber body 13, the SIM card sliding block 12 is slidably disposed in the first cavity 16, one end of the elastic device 11 is connected with the SIM card sliding block 12, the other end of the elastic device 11 is connected with the card chamber body 13, and the elastic device 11 is used for driving the SIM card sliding block 12 to move towards the opening 17; the card chamber body 13 is further provided with two first SIM card ports 18, the first SIM card ports 18 are arranged at one end of the card chamber body 13 close to the opening 17, and the two first SIM card ports 18 are arranged oppositely; referring to fig. 11 to 12, the bevel is a bevel with a chamfer angle or a fillet angle, so that the bevel and the front cover form a non-zero included angle, and when the SIM card is loaded, the SIM card touches the chamfer to change the traveling direction, thereby loading the SIM card.

Referring to fig. 11 to 12, the front cover 15 is disposed on the opening 17, one end of the front cover 15 close to one of the first SIM sockets 18 is provided with a bevel 19, and when the front cover 15 is pressed, the bevel 19 faces one of the first SIM sockets 18; the limiting mechanism 14 is arranged on the card chamber body 13 and the front cover 15, and the limiting mechanism 14 is used for preventing the front cover 15 from falling off from the card chamber body 13. It should be noted that the first cavity 16 is used for storing a plurality of SIM cards 60; and the cross section of the first cavity 16 (i.e. the cross section of the card chamber body 13) is matched with the SIM card 60, the SIM card 60 reciprocates in the first cavity 16, and the length of the first cavity 16 is arranged along the length direction of the card chamber body 13. Loading, as referred to hereinafter, refers to loading the SIM card 60 into the magazine structure and ejecting the SIM card 60 from the magazine structure 10.

It should be further noted that the two first SIM sockets 18 are disposed oppositely, that is, the two first SIM cards are located on the same plane, the first SIM socket 18 on the side close to the bezel 19 is used for allowing the SIM card 60 to enter and exit, and the first SIM socket 18 on the side far from the bezel 19 is used for allowing the card needle to enter and exit. It should be further noted that the SIM card slider 12 and the front cover 15 are in a split type, that is, the SIM card 60 is disposed between the SIM card slider 12 and the front cover 15. The bevel 19 is a surface with a rounded corner or a beveled corner, and when the SIM card 60 touches the bevel 19, the original moving direction is changed, that is, the SIM card 60 is tilted towards the first cavity 16, so that the SIM card 60 can enter the first cavity 16 conveniently, and the filling efficiency of the SIM card 60 is improved. It should be further noted that the limiting mechanism 14 prevents the front cover 15 from falling off the card chamber body 13.

In practical use, referring to fig. 8 to 10, when a SIM card 60 needs to be ejected from the magazine structure 10 of the one SIM card, a card pin enters from the first SIM card slot 18 on the side away from the bezel 19, and simultaneously ejects a SIM card, the ejected SIM card 60 exits from the first SIM card slot 18 on the side close to the bezel 19; when the SIM card 60 needs to be loaded into the card chamber structure 10 of the one SIM card, the operator presses the front cover 15 to make the bezel 19 face the first SIM card opening 18, at this time, the SIM card 60 is inserted from the first SIM card opening 18 near one side of the bezel 19, the inserted SIM card 60 touches the bevel angle on the bezel 19, the SIM card 60 will change the insertion direction, so that the SIM card 60 is tilted toward the first cavity 16, and as the SIM card 60 is still being inserted, the SIM card 60 pushes the SIM card sliding block 12 to move away from the front cover 15 until the SIM card 60 completely enters the first cavity 16, thereby completing the loading of the SIM card 60.

It should be noted that when the operator presses the front cover 15, the SIM card 60 and the SIM card slider 12 in the first cavity 16 will move together in a direction away from the front cover 15, and the bezel 19 will face the first SIM card slot 18 on the side close to the bezel 19, waiting for the loading of the SIM card 60. When the front cover 15 is not pressed, the first SIM card port 18 near one side of the bezel 19 cannot see the bezel 19, and only the SIM card 60 or the SIM card slider 12 is visible.

Different from the prior art, in the above technical solution, the insertion direction of the SIM card 60 is changed by the arrangement of the bezel 19 on the front cover 15, so that the SIM card 60 can be quickly loaded into the first cavity 16; meanwhile, the elastic device 11 and the SIM card sliding block 12 provide kinetic energy for the SIM card 60, so that the SIM card 60 can continuously exit from the card chamber body 13, and the SIM card 60 can be prevented from deviating, thereby protecting the SIM card 60. The bezel 19, the elastic device 11 and the SIM card slider 12 can improve the efficiency of taking and placing the SIM card 60, and can prevent the SIM card 60 from shifting.

Referring to fig. 7, in order to prevent the front cover 15 from falling off from the card chamber body 13, in this embodiment, the limiting mechanism 14 includes: ridges 141 and grooves 142; the protruding strips 141 are located on the side walls of the two sides of the first SIM bayonet 18, the grooves 142 are disposed on the front cover 15, the protruding strips 141 are disposed in the grooves 142, and the grooves 142 reciprocate in the length direction perpendicular to the protruding strips 141. It should be noted that the length direction of the protruding strip 141 is perpendicular to the length direction of the card hopper body 13, and similarly, the length direction of the groove 142 is perpendicular to the length direction of the card hopper body 13; it should be noted that, in the present embodiment, two side walls of the groove 142 are used for displaying the moving range of the front cover 15. Specifically, when the front cover 15 is pressed, the sidewall of the groove 142 close to the upper surface of the front cover 15 contacts the rib 141 to prevent the front cover 15 from moving further into the first cavity 16, and the chamfer faces one of the first SIM sockets 18; when the front cover 15 is released, the side wall of the groove 142 away from the upper surface of the front cover 15 contacts the convex strip 141, so that the front cover 15 is prevented from falling off.

In some embodiments, in order to prevent the bezel 19 from being misaligned with the first SIM card holder 18 when the front cover 15 is pressed, a stop is further disposed on the inner wall of the card chamber body 13, and the stop is used to prevent an operator from pressing the front cover 15 too much, so that the bezel 19 cannot be aligned with the first SIM card holder 18. The provision of the stopper is not essential, and when the operation of pressing the front cover 15 is performed by the cam 41 or the like, misalignment can be avoided by only setting the degree of pressing force in advance. It should be further noted that, while the limiting rod limits the position, it is also required to ensure that the surface of the front cover 15 away from the first cavity 16 can perform a pressing operation.

Referring to fig. 14, in some embodiments, a plurality of pick-and-place structures 20 are further disposed on one side of the card bin structure, and the pick-and-place structures correspond to the card bin structures one to one.
