[0002] SIM card holders play a crucial role in modern communication devices. They not only provide a reliable interface for SIM cards but also ensure that users can conveniently and quickly read and use the information in SIM cards. With the popularization and evolution of smart devices, people have put forward higher requirements for the stability and usability of SIM card holders, enabling them to not only meet the basic needs of connection and communication but also demonstrate better user - friendliness in practical applications.

[0003] Currently, in order to achieve the basic functions of SIM card holders, common designs on the market mostly adopt spring - type designs, enabling SIM cards to automatically eject without damage. In addition, some double - layer card holder designs allow the SIM cards on the card tray to be inserted along the track and fixed in the slot to achieve more stable contact and more convenient plug - and - unplug operations. The design of the card tray slot usually takes into account the fixation and stability of the SIM card insertion position to ensure that the SIM card can still be tightly connected to the card holder when the device moves or is impacted.

[0004] However, existing card holders have certain limitations in practical applications. Especially when installing or removing SIM cards, the SIM cards are prone to detaching from the card tray, resulting in low installation efficiency and inconvenient loading and unloading operations.

[0005] Therefore, based on the above problems, the existing technology needs to be improved. Utility Model Content

[0037] The following further describes the present application in detail with reference to the accompanying drawings.

[0038] In this embodiment, with reference to Figures 1-4, a self - ejecting double - layer card seat with a card - locking function, includes a lower body 1 and an upper body 2. The lower body 1 and the upper body 2 enclose to form a slot 3. A lower terminal 4 is arranged on the lower body 1, and an upper terminal 5 is arranged on the upper body 2. Specifically, the lower body 1 is made of high - strength aluminum alloy material, which can effectively protect the internal structure and reduce the overall weight. The upper body 2 is made of corrosion - resistant stainless - steel material and has a long service life. The lower body 1 and the upper body 2 are detachably connected by the cooperation of an installation groove 19 and an installation pin 20. The installation groove 19 is a U - shaped structure, and the installation pin 20 is a circular columnar structure. During installation, the installation pin 20 of the upper body 2 is inserted into the installation groove 19 of the lower body 1 to make the upper and lower bodies 1 fit tightly, ensuring the stability of the connection. When disassembly is required, just pull out the installation pin 20 from the installation groove 19.

[0039] A card holder 6 is arranged in the slot 3. A lower card slot 7 is arranged on one side of the card holder 6 close to the lower terminal 4, and an upper card slot 8 is arranged on one side of the card holder 6 close to the upper terminal 5. The card holder 6 is made of high - strength engineering plastic and has good compressive resistance. Both the lower card slot 7 and the upper card slot 8 are rectangular - groove structures for placing SIM cards. A clamping block 10 is arranged in each card slot. The card holder 6 is provided with a deformation groove 11 corresponding to the clamping block 10. When the SIM card is inserted, the slot wall of the lower card slot 7 or the upper card slot 8 deforms through the deformation groove 11 to make the clamping block 10 avoid the installation of the SIM card. After the SIM card is installed, the slot wall of the lower card slot 7 or the upper card slot 8 rebounds through the deformation groove 11 to make the clamping block 10 cooperate with the slot wall of the card slot to squeeze the SIM card, increasing the friction force and the fixing effect. The clamping block 10 can be made of rubber material, which has good elasticity and can effectively prevent the SIM card from loosening. Specifically, the clamping block 10 includes but is not limited to rubber material, and can also be made of silica gel material or other elastic materials. The cooperation design of the clamping block 10 and the deformation groove 11 ensures the stable fixation of the SIM card in the card holder 6, avoiding the loosening or displacement of the SIM card.

[0040] Referring to FIGS. 2-5, a resilient wall locking structure 9 is provided in the slot 3. The cartridge 6 is clamped by this structure, so that the cartridge 6 is inserted and installed in the slot 3, or the cartridge 6 is ejected from the slot 3. The resilient wall locking structure 9 includes a slider 91 provided in the slot 3. The slider 91 is made of high-toughness engineering plastic. A clamping member 92 is provided on the slider 91, and a clamping groove 12 is provided on the cartridge 6. A through groove 14 is formed by the concave of the slider 91. An installation post 95 is provided at the bottom of the slot 3 of the slot 3, and an elastic member 94 is sleeved on the installation post 95. The elastic member 94 can be a metal spring or a rubber spring. One end abuts against the bottom of the slot 3 of the slot 3, and the other end abuts against the bottom of the through groove 14. The slider 91 cooperates with the bottom of the slot 3 to squeeze or release the elastic member 94, realizing the locking and unlocking functions of the cartridge 6. Specifically, when the cartridge 6 is inserted into the slot 3, the slider 91 is squeezed, so that the elastic member 94 begins to be compressed and stores energy. When it is necessary to eject the cartridge 6, the elastic member 94 releases the stored energy, pushes the slider 91 to move, and drives the cartridge 6 to eject from the slot 3.

[0041] Referring to Figures 5-6 , specifically, a convex block 132 protrudes from the middle of the chute 13. The chute 13 is Y-shaped and includes a forward groove 133 and a retraction groove 134 that communicate with each other. The retraction groove 134 is linear and is arranged along the insertion direction of the cartridge 6. A recess 135 is provided at one end of the retraction groove 134 close to the bottom of the slot 3. The inner wall of the recess 135 on the side away from the bottom of the slot 3 is inclined towards the direction of the forward groove 133. The height of the bottom wall of the forward groove 133 gradually increases along the opposite insertion direction of the cartridge 6. A guide groove 136 is formed by the depression at one end of the forward groove 133 away from the bottom of the slot 3. A first limit guide block 15 is provided at the conduction position of the guide groove 136 and the limit groove 131. One end of the pull rod 93 fitted with the slider 91 is introduced into the limit groove 131 through the guide groove 136. The limit groove 131 is arc-shaped and has a guiding surface 16. A second limit guide block 17 is provided at the conduction position of the limit groove 131 and the retraction groove 134. One end of the pull rod 93 fitted with the slider 91 is introduced into the retraction groove 134 through the guiding surface 16 and the second limit guide block 17. Specifically, the pull rod 93 slides in the chute 13 along the limit guide block, and drives the cartridge 6 to be locked or ejected through the extrusion of the slider 91 and the energy release of the elastic member 94.

[0042] In this embodiment, the lower body 1, the upper body 2, and the slot 3 are all made of aluminum alloy material. Combined with the specific structural design, the overall structural stability and reliability of the card seat are improved, which is convenient for production and maintenance. The cartridge 6 is made of high-strength engineering plastic to ensure that it is not easily damaged during use. The design of the clamping block 10 and the deformation groove 11 can effectively fix the SIM card. The locking mechanism composed of the slider 91 and the elastic member 94 of the resilient wall locking structure 9 enables the cartridge 6 to be automatically locked when sliding in, and releases energy through the elastic member 94 when it is necessary to take it out, realizing quick ejection. The whole device has a compact structure, convenient operation, and good stability, and has significant technical and practical advantages.

[0043] Specifically,

[0044] SIM card installation:

[0045] Insert the SIM card into the lower card slot 7 and / or the upper card slot 8 of the card tray 6 respectively. The clamping block 10 cooperates with the deformation groove 11 to firmly fix the SIM card. Then insert the card tray 6 into the slot 3 formed by enclosing the lower main body 1 and the upper main body 2. During the insertion process, the card tray 6 pushes the slider 91 to move, and the pull rod 93 slides along the forward groove 133 from the initial position in the chute 13 of the slider 91. As the card tray 6 continues to be inserted, the pull rod 93 enters the limit groove 131 under the guidance of the guide groove 136 and the first limit guide block 15, and at this time the elastic member 94 is compressed. When the pull rod 93 completely enters the limit groove 131, the card tray 6 is firmly locked in the slot 3, completing the installation of the SIM card.

[0046] SIM card removal:

[0047] When the SIM card needs to be removed, apply a certain external force to the card tray 6 to change the force received by the pull rod 93 in the limit groove 131. Under the action of the guiding surface 16 of the arc-shaped limit groove 131 and the second limit guide block 17, the pull rod 93 enters the retraction groove 134 from the limit groove 131. With the continuous action of the external force, the pull rod 93 slides along the retraction groove 134. Since the retraction groove 134 is provided with a recess 135 at one end close to the bottom of the slot 3, and the inner wall on the side of the recess 135 away from the bottom of the slot 3 is inclined towards the forward groove 133, the pull rod 93 can smoothly slide and be positioned in the retraction groove 134. When the pull rod 93 slides to a certain position, the elastic member 94 releases the stored energy, pushes the slider 91 to move, and the slider 91 drives the card tray 6 to pop out of the slot 3 through the pull rod 93, completing the removal of the SIM card.

[0048] Referring to Figures 1-2 , specifically, an outer shell 18 is provided on the lower main body 1 and the upper main body 2. The outer shell 18 can be made of polycarbonate material, which has good protection performance and durability, and can effectively protect the internal components from the external environment. The outer shell 18 is installed by a combination of screws and buckles, which is convenient for disassembly and maintenance. By setting the outer shell 18, the external protection performance of the card holder is improved.

[0049] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
