[0029] With the development of mobile terminal technology, mobile terminal electronic devices have become increasingly versatile and have become one of the most important tools in people's daily lives and work. Some mobile terminal electronic devices, such as mobile phones, tablets, and smart wearable devices, can be equipped with integrated circuit cards such as SIM cards (Subscriber Identity Modules) and memory cards to realize corresponding functions.

[0030] Currently, integrated circuit cards are usually installed in electronic devices through a card tray that matches the electronic device. However, the card tray locking structure of related technologies often creates a strong connection between the card tray and the electronic device, and external tools (such as ejector pins) are often required for disassembly, which makes it difficult to disassemble without tools; or, the card tray locking structure creates a weak connection between the card tray and the electronic device, which can easily affect the locking effect of the card tray locking structure after several disassembly and assembly, resulting in a weakened holding force between the card tray and the electronic device, which in turn causes the card tray to easily slip out of the electronic device, resulting in poor reliability.

[0031] Based on this, the inventor designed a card holder locking structure, which realizes the connection between the card holder and the shell through the cooperation between the damping structure and the installation groove, achieving a balance between the disassembly and assembly performance of the card holder and the shell and the connection reliability, and has greater reliability.

[0032] Please refer to Figures 1 to 3 , an embodiment of the present application provides a card holder locking structure 100, which includes a shell 10 and a card holder 20, wherein the shell 10 includes a main body 11 with a accommodating space 101 and a through slot 12 arranged on the main body 11, and the through slot 12 is connected to the accommodating space 101; the card holder 20 includes a supporting portion 21 and a connecting portion 22, the supporting portion 21 is connected to the connecting portion 22 and is used to support an integrated circuit card (not shown); one of the main body 11 and the connecting portion 22 is provided with a damping structure 102, and the other is provided with a mounting groove 103, and the main body 11 and the connecting portion 22 are detachably connected through the damping structure 102 and the mounting groove 103.

[0033] The card tray locking structure 100 is used to install integrated circuit cards such as SIM cards and memory cards into electronic devices to achieve different functions, such as using SIM cards to enable electronic devices to have communication functions, or using memory cards to increase the storage space of electronic devices.

[0034] The electronic device may be a mobile phone, a tablet computer or a smart wearable device. In these embodiments of the present invention, the integrated circuit card is a SIM card and the electronic device is a watch as an example for description.

[0035] The card tray locking structure 100 includes a housing 10 and a card tray 20 , wherein the housing 10 is an external structure of the electronic device.

[0036] The shell 10 includes a main body 11 having a accommodating space 101 and a through groove 12 arranged in the main body 11. A possible implementation method is that the shell 10 itself is an enclosing structure to form the aforementioned accommodating space 101 for accommodating other components of the electronic device such as power supply, control elements, display elements, etc., or the shell 10 limits the external frame structure of the electronic device and cooperates with other components of the electronic device to jointly enclose the aforementioned accommodating space 101.

[0037] Through-slot 12 is provided in body 11 and communicates with accommodating space 101. This refers to a structure within body 11 that connects accommodating space 101 to the outside world. In these embodiments of the present invention, card tray 20 can be mounted to body 11 via through-slot 12, allowing an integrated circuit card (ICC) supported by card tray 20 to be installed within accommodating space 101. This allows the ICC card to be read and used by components of the electronic device within accommodating space 101, thereby achieving the corresponding functions.

[0038] The card tray 20 is a structure in the card tray locking structure 100 specifically used for supporting an integrated circuit card.

[0039] The card tray 20 includes a supporting part 21 and a connecting part 22. The supporting part 21 and the connecting part 22 are connected and are used to support the integrated circuit card. The supporting part 21 is the structure in the card tray 20 for supporting the integrated circuit card, and the connecting part 22 is the structure in the card tray 20 for connecting the card tray 20 with the shell 10.

[0040] The supporting portion 21 is connected to the connecting portion 22. A possible implementation method is that the supporting portion 21 and the connecting portion 22 are fixedly connected by welding or even integrally formed to improve the structural consistency between the supporting portion 21 and the connecting portion 22; or, in some embodiments, the supporting portion 21 and the connecting portion 22 can be provided with a detachable connection through connectors such as screws and screws, a snap-fit ​​structure, etc., to facilitate the maintenance and replacement of the card tray 20 during subsequent use, thereby improving the convenience of maintenance and replacement of the card tray 20.

[0041] The support portion 21 is used to support the integrated circuit card. A possible implementation method is that an integrated circuit card limiting structure is provided in the support portion 21. When the user needs to install the integrated circuit card into the electronic device, the user can first remove the card tray 20 from the electronic device, install the integrated circuit card into the integrated circuit card limiting structure of the support portion 21, and then install the card tray 20 into the shell 10 to achieve the installation of the integrated circuit card; or, in some embodiments, the support portion 21 can be provided without a limiting function for the integrated circuit card, and when the user installs the card tray 20 into the shell 10, the support portion 21 can cooperate with other structures of the electronic device in the accommodating space 101 to achieve limiting and fixation of the integrated circuit card. This application does not limit this.

[0042] One of the main body 11 and the connecting part 22 is provided with a damping structure 102, and the other is provided with a mounting groove 103. The main body 11 and the connecting part 22 are detachably connected through the damping structure 102 and the mounting groove 103, wherein the damping structure 102 and the mounting groove 103 cooperate with each other to realize the installation and disassembly of the card tray 20 and the shell 10.

[0043] In some embodiments, the damping structure 102 itself can be set to have a certain elastic deformation ability. When the user installs the card tray 20 to the shell 10, the damping structure 102 can deform itself to allow relative displacement between the card tray 20 and the shell 10. When the damping structure 102 moves to a position matching the installation slot 103 with the relative displacement between the card tray 20 and the shell 10, it can be clamped into the installation slot 103 through its own elastic deformation, thereby achieving the locking effect of the card tray locking structure 100 and limiting the continued relative displacement between the card tray 20 and the shell 10.

[0044] In this way, during normal use of the electronic device, when no external force is applied to the card tray 20, the relative position relationship between the card tray 20 and the shell 10 can be kept stable through the cooperation between the damping structure 102 and the mounting slot 103; and when the user needs to remove the card tray 20, the damping structure 102 can be elastically deformed and compressed again by applying a certain external force on the card tray 20. At this time, the user can remove and separate the card tray 20 from the shell 10 by pulling.

[0045] In some embodiments, the damping structure 102 can also be set as a hard structure. When the user installs the card tray 20 to the shell 10, the damping structure 102 causes a slight deflection in the moving direction through contact with the main body 11, so that relative displacement can occur between the card tray 20 and the shell 10. When the damping structure 102 moves to a position matching the installation slot 103 as the card tray 20 and the shell 10 move relative to each other, it can be stuck in the installation slot 103, thereby realizing the locking effect of the card tray locking structure 100, limiting the continued relative displacement between the card tray 20 and the shell 10.

[0046] In this way, during normal use of the electronic device, when no external force is applied to the card tray 20, the relative position relationship between the card tray 20 and the shell 10 can be kept stable through the cooperation between the damping structure 102 and the mounting slot 103; and when the user needs to remove the card tray 20, the card tray 20 can be subjected to a certain external force, and the mounting slot 103 can be used to drive the damping structure 102 to deflect slightly again, so that the card tray 20 and the shell 10 can be relatively displaced again. At this time, the user can also remove and separate the card tray 20 from the shell 10 by pulling.

[0047] The technical solution of the present application is to provide one of the main body 11 and the connecting part 22 with a damping structure 102, and the other with a mounting groove 103. The main body 11 and the connecting part 22 are detachably connected through the damping structure 102 and the mounting groove 103. On the one hand, the card tray 20 and the shell 10 can be disassembled and assembled without the aid of external tools, and have good disassembly and assembly convenience; at the same time, when the card tray 20 is installed in the shell 10, the damping structure 102 and the mounting groove 103 cooperate to lock the card tray 20 and the shell 10, reducing the risk of the card tray 20 naturally slipping out during use and improving reliability.

[0048] In some embodiments, the through groove 12 passes through the main body 11 along the first direction X, the main body 11 includes a first surface 111, the connecting portion 22 includes a second surface 221, the first surface 111 and the second surface 221 are parallel and both parallel to the first direction X; the damping structure 102 is disposed on one of the first surface 111 and the second surface 221, and the mounting groove 103 is disposed on the other of the first surface 111 and the second surface 221.

[0049] The through slot 12 passes through the main body 11 along the first direction X, which means that the through slot 12 is a slot structure that is recessed along a straight line. During the installation of the card tray 20, the support portion 21 of the card tray 20 can be inserted into the accommodating space 101 through the through slot 12 along the first direction X to be electrically connected to other components of the electronic device in the accommodating space 101.

[0050] The main body 11 includes a first surface 111, and the connecting portion 22 includes a second surface 221. The first surface 111 and the second surface 221 are parallel and both parallel to the first direction X. As mentioned above, the first direction X is the direction in which the card tray 20 in the present invention is inserted into the through slot 12, that is, the direction in which the card tray 20 and the shell 10 undergo relative displacement during installation or removal.

[0051] At this time, the first surface 111 and the second surface 221 are parallel and parallel to the first direction X, and the damping structure 102 is disposed on one of the first surface 111 and the second surface 221, and the mounting groove 103 is disposed on the other of the first surface 111 and the second surface 221. During installation or removal of the card tray 20, the user pushes or pulls the card tray 20 along the first direction X, causing the first surface 111 and the second surface 221 to move relative to each other, thereby changing the relative positional relationship between the damping structure 102 and the mounting groove 103 respectively disposed thereon. When the damping structure 102 moves to coincide with the position of the mounting groove 103, the card tray and the housing 10 are fixed.

[0052] In some embodiments, the damping structure 102 is disposed on the second surface 221, and the mounting groove 103 is disposed on the first surface 111. This means that when the card tray 20 is mounted on the housing 10, the damping structure 102 is connected to the second surface 221, protruding from the second surface 221 toward the first surface 111; the mounting groove 103 is disposed on the first surface 111, recessed from the first surface 111 toward away from the second surface 221.

[0053] In some embodiments, the damping structure 102 and the connecting portion 22 are integrally formed to improve the production efficiency of the damping structure 102 , while increasing the structural consistency between the damping structure 102 and the connecting portion 22 , thereby reducing the risk of damage to the damping structure 102 during repeated use.

[0054] In some embodiments, the damping structure 102 includes a first main body portion 1021 and a second main body portion 1022 connected along a first direction X, and the first main body portion 1021 is close to the accommodating space 101 along the first direction X; along the direction of the through groove 12 pointing to the accommodating space 101, the thickness of the first main body portion 1021 gradually decreases, and the thickness of the second main body portion 1022 gradually increases.

[0055] The first main body 1021 and the second main body 1022 are two connected parts of the damping structure 102, wherein the first main body 1021 is arranged close to the accommodating space 101 along the first direction X, which means that the first main body 1021 is the part of the damping structure 102 that is closer to the accommodating space 101, that is, during the installation stage of the card holder 20 and the shell 10, the first main body 1021 first contacts the shell 10.

[0056] In these embodiments of the present invention, the thickness dimension of the first main body 1021 is set to gradually decrease in the direction of the through groove 12 pointing to the accommodating space 101. In the embodiment where the damping structure 102 can undergo elastic deformation, it is beneficial for the damping structure 102 to gradually deform itself during the installation process of the card holder 20, thereby protecting the damping structure 102; and in the embodiment where the damping structure 102 is a hard structure, such a gradual change in the thickness of the first main body 1021 can also provide a guide for the installation of the card holder 20, thereby causing the card holder 20 to undergo a slight deflection during the installation process, thereby reducing the difficulty of relative displacement between the card holder 20 and the shell 10.

[0057] Correspondingly, the second main body 1022 is the portion of the damping structure 102 that is disposed away from the accommodating space 101 . During the disassembly phase of the card tray 20 and the housing 10 , the second main body 1022 first contacts the housing 10 .

[0058] In these embodiments of the present invention, the thickness dimension of the second main body 1022 is set to gradually increase in the direction of the through groove 12 pointing to the accommodating space 101. In the embodiment where the damping structure 102 can undergo elastic deformation, it is beneficial for the damping structure 102 to gradually deform itself during the disassembly process of the card holder 20, and it can also protect the damping structure 102 during the disassembly stage; and in the embodiment where the damping structure 102 is a hard structure, such a gradual change in the thickness of the second main body 1022 can also provide a guide for the disassembly of the card holder 20, thereby causing the card holder 20 to undergo a slight deflection during the disassembly process, reducing the difficulty of relative displacement between the card holder 20 and the shell 10.

[0059] In some embodiments, the surface of the first body portion 1021 facing away from the second surface 221 is a flat surface. Combined with the above content, that is, the surface of the first body portion 1021 facing away from the second surface 221 is a flat inclined surface, this design is more conducive to the installation of the card tray 20.

[0060] In an embodiment where the damping structure 102 can undergo elastic deformation, setting the surface of the first main body 1021 away from the second surface 221 to a flat inclined surface is conducive to the gradual deformation of the damping structure 102 itself, reducing the amount of extrusion of the damping structure 102 when it is deformed, and thereby reducing the risk of damage to the damping structure 102 during use; and in an embodiment where the damping structure 102 is a hard structure, setting the surface of the first main body 1021 away from the second surface 221 to a flat inclined surface is also conducive to the gradual slight deflection of the damping structure 102 during installation, thereby improving the mobility between the tray 20 and the shell 10.

[0061] In some embodiments, the surface of the second main body portion 1022 facing away from the second surface 221 is a curved surface, and the thickness increase rate of the second main body portion 1022 gradually decreases along the direction of the through groove 12 pointing to the accommodating space 101 .

[0062] The rate of increase in the thickness of the second main body 1022 gradually decreases along the direction from the through slot 12 to the accommodating space 101. This means that the surface of the second main body 1022 facing away from the second surface 221 is a curved surface, and this curved surface is an "outwardly convex" type surface. In this way, because the mounting slot 103 is a slot structure that matches the damping structure 102, after the card tray 20 is installed in the housing 10 and the damping structure 102 is located within the mounting slot 103, this curved surface structure has a certain limiting effect, thereby preventing the card tray 20 from sliding out of the housing 10 during normal use, thereby improving the stability of the card tray locking structure 100.

[0063] When the user needs to remove the card tray 20 to replace or repair the integrated circuit card, pressure can be applied to the damping structure 102 through the connecting portion 22. In an embodiment in which the damping structure 102 can undergo elastic deformation, the damping structure 102 can gradually deform under the combined action of the pulling force applied by the user and the mounting slot 103, thereby allowing the card tray 20 to undergo relative displacement with the housing 10, allowing the user to withdraw the card tray 20; in an embodiment in which the damping structure 102 is a rigid structure, the curved structure of the mounting slot 103 and the damping structure 102 can decompose a portion of the user's pulling force into a tensile force along the thickness direction, thereby causing the damping structure 102 to undergo a slight deflection, causing the damping structure 102 to gradually break away from the limit of the mounting slot 103, allowing the card tray 20 to undergo relative displacement with the housing 10.

[0064] In some embodiments, there are two damping structures 102 and two mounting slots 103 . The mounting slots 103 are disposed on the main body 11 , and the damping structure 102 is disposed on the connecting portion 22 . The projection of the mounting slots 103 along the first direction X is offset from the through slot 12 .

[0065] In these embodiments of the present invention, the mounting groove 103 is disposed on the main body 11 , and correspondingly, the damping structure 102 is disposed on the connecting portion 22 .

[0066] There are two damping structures 102 and two mounting grooves 103, and the projections of the two mounting grooves 103 along the first direction X are staggered with the through groove 12 to reduce the impact of the connection between the damping structure 102 and the mounting groove 103 on the support portion 21 entering the accommodating space 101, thereby improving the connection effect between the integrated circuit card and the components of the electronic device located in the accommodating space 101.

[0067] For example, in an embodiment where the cross-sectional shape of the through slot 12 along the direction perpendicular to the first direction X is a rectangle, two mounting grooves 103 can be arranged at both ends of the through slot 12 along the length direction, and spaced apart from the through slot 12; accordingly, in the card holder 20, the support portion 21 is also a rectangular structure matching the through slot 12, and the two damping structures 102 are respectively arranged at the two ends of the connecting portion 22 corresponding to the support portion 21 along the length direction, and are respectively arranged corresponding to the two mounting grooves 103.

[0068] In some embodiments, the damping structure 102 is a rubber block, a plastic block, or a metal alloy block. The rubber block corresponds to the embodiment in which the damping structure 102 is elastically deformable, while the plastic block or the metal alloy block corresponds to the embodiment in which the damping structure 102 is a hard structure.

In these embodiments of the present invention, the electronic device may be a watch, and the card tray 20 is used to install a SIM card into the watch to enable the watch to have a communication function.

[0070] In other embodiments of the present invention, the electronic device may be a mobile phone, a tablet computer or other smart wearable device. The integrated circuit card may also be, but is not limited to, a SIM card or a memory card.
