Description

Technical Field

[0001] This application relates to the field of SIM card fixing structure technology, and further to a SIM card fixing structure and a smart host. Background Technology

[0002] In recent years, with the advancement of technology and the development of science and technology, my country's smart host industry has developed rapidly; smart wearable devices such as smartwatches have become an indispensable part of modern life.

[0003] Currently, smart devices on the market, such as smartwatches, generally possess communication, location, interaction, and reminder functions in addition to the standard time-telling function, greatly facilitating users' daily lives. In the industry, the communication functions of smartwatches and other smart devices require a SIM card. In related technologies, the base plate of the smart device typically has an installation slot. After the SIM card is fixedly embedded in the installation slot, the base plate is fixedly fastened to the corresponding SIM card slot on the smart device, ensuring stable contact between the pins of the SIM card and the corresponding pins in the SIM card slot area. This allows for the removable and stable installation of the SIM card within the smart device. However, for the aforementioned technologies, for small-sized smart devices, such as smartwatches, the base plate is even smaller. Incorporating a SIM card installation structure into the base plate complicates the structure, increasing both the manufacturing difficulty of the base plate and the production cost of the smart device, indicating areas for improvement. Utility Model Content

[0004] The purpose of this application is to provide a SIM card fixing structure and a smart host, which effectively reduces the production difficulty and cost of the corresponding smart host equipment by optimizing the SIM card installation and fixing method, thereby promoting cost reduction and efficiency improvement for enterprises.

[0005] The technical solution provided in this application is as follows:

[0006] On one hand, this application provides a SIM card fixing structure for stably installing a SIM card in the SIM card slot of a smart host, including:

[0007] A positioning component is provided with an installation position, the shape of which is adapted to the shape of the SIM card so as to detachably install the SIM card; the shape of the positioning component is adapted to the shape of the SIM card slot of the smart host, and the positioning component is adapted to slide and embed itself in the SIM card slot along the depth direction of the SIM card slot until the first spring on the SIM card stably contacts the corresponding second spring on the bottom wall of the SIM card slot;

[0008] A card cover is provided on one side of the positioning component and is detachably connected to the smart host. It is used to cover the SIM card slot opening so as to stably confine the positioning component and the SIM card inside the SIM card slot.

[0009] This application provides a SIM card fixing structure. In practical applications, when installing a SIM card into the SIM card slot of a smart host, the SIM card is first installed in the mounting position of the positioning member, keeping the side of the first spring on the SIM card facing the SIM card slot. Then, the positioning member is slid and embedded in the SIM card slot along the depth direction of the SIM card slot until the first spring on the SIM card stably contacts the corresponding second spring on the bottom wall of the SIM card slot (or, the positioning member is first slid and embedded in the SIM card slot along the depth direction of the SIM card slot, then the side of the first spring on the SIM card facing the SIM card slot is kept in the mounting position of the positioning member until the first spring on the SIM card stably contacts the corresponding second spring on the bottom wall of the SIM card slot). After that, the SIM card slot opening is covered by a card cover, and the card cover is fixedly installed on the smart host, completing the stable installation of the SIM card in the SIM card slot of the smart host.

[0010] In this way, the SIM card positioning structure and the card cover are set up separately. The positioning structure only needs to be able to stably install the SIM card and limit the docking position of the SIM card in the SIM card slot, while the card cover only needs to be able to be detachably connected to the smart host and completely cover the opening of the SIM card slot. The two can be designed in various structural forms, and the manufacturing process is simple and easy to implement. This replaces the solution of molding the SIM card mounting structure as a whole on the base plate of the smart host device, reducing the production difficulty of the SIM card fixing structure and the production cost of the corresponding smart host device. At the same time, the SIM card installation operation is simple and convenient, taking into account the user experience and effectively promoting cost reduction and efficiency improvement for enterprises.

[0011] In some embodiments, the mounting position includes a mounting groove, which is formed in the middle of the positioning member and located on one side of the positioning member in the thickness direction;

[0012] The positioning element has a through hole on the bottom wall of the mounting groove.

[0013] This application provides a SIM card fixing structure. In practical applications, when installing a SIM card into the SIM card slot of a smart host, the first spring tab on the SIM card is kept away from the bottom wall of the mounting slot, and the SIM card is installed in the mounting slot. Then, keeping the first spring tab on the SIM card facing the SIM card slot, a positioning member is slidably embedded into the SIM card slot along the depth direction of the SIM card slot until the first spring tab on the SIM card stably contacts the corresponding second spring tab on the bottom wall of the SIM card slot. Finally, a card cover is used to cover the opening of the SIM card slot, thus stably installing the SIM card in the smart host device. When it is necessary to remove or replace the SIM card, after the positioning member is removed from the SIM card slot, it pushes the SIM card from the through hole toward the opening of the mounting slot, thus allowing the SIM card to be removed from the mounting slot. In this way, by opening the mounting slot, a mounting position for installing the SIM card is formed, and by opening the through hole, the removal of the SIM card is assisted. The positioning member has a simple structure and is easy to manufacture, which helps to further reduce the cost investment of enterprises in SIM card fixing solutions and is conducive to energy saving and cost reduction for enterprises.

[0014] In some embodiments, the mounting position includes a mounting hole, which is formed in the middle of the positioning member and extends through the thickness direction of the positioning member;

[0015] The mounting hole is adapted for the SIM card to slide and be embedded along the thickness direction of the positioning member until the first spring contact is stably in contact with the second spring.

[0016] The SIM card fixing structure provided in this application, in practical applications, when installing a SIM card into the SIM card slot of a smart host, firstly, the positioning member is slidably embedded into the SIM card slot along the depth direction of the SIM card slot, then, keeping the side of the first spring on the SIM card facing the SIM card slot, the SIM card is slidably embedded into the mounting hole along the thickness direction of the positioning member until the first spring on the SIM card stably contacts the corresponding second spring on the bottom wall of the SIM card slot; then, the SIM card slot opening is covered by a card cover, and the SIM card can be stably installed in the smart host device.

[0017] When you need to remove or replace the SIM card, take the positioning piece out of the SIM card slot and push the SIM card out from the mounting hole.

[0018] In this way, by opening an installation hole, an installation position for installing a SIM card is formed in the inner cavity of the installation hole. The installation position setting method is simple, and the installation and removal of SIM cards is convenient. While ensuring the user experience, it also helps to further promote energy conservation and cost reduction for enterprises.

[0019] In some embodiments, the inner wall of the mounting hole is provided with a guide slope at one end of the SIM card slot opening to assist the SIM card in quickly entering the mounting position.

[0020] In some embodiments, the sidewall of the positioning element is formed with an annular waterproof protrusion along its circumference;

[0021] When the positioning component is embedded in the SIM card slot, the annular waterproof protrusion abuts against the side wall of the corresponding position of the SIM card slot and slides in close fit with the side wall of the SIM card slot along the depth direction of the SIM card slot.

[0022] This application provides a SIM card fixing structure with an annular waterproof protrusion on the side wall of the positioning component. This improves the waterproof performance of the SIM card installation position while achieving a tight-fitting sliding connection between the positioning component and the side wall of the SIM card slot. In other words, it enables a detachable connection between the positioning component and the smart host. The structure is simple, ingenious, and multifunctional, which helps to further promote cost reduction and efficiency improvement for enterprises.

[0023] In some embodiments, the sidewall of the positioning member is provided with a handle at one end of the SIM card slot opening to assist in removing the positioning member from the SIM card slot.

[0024] In some embodiments, the positioning member has a first waterproof groove at one end that abuts against the bottom wall of the SIM card slot. The first waterproof groove surrounds the mounting position and a first waterproof rubber ring is detachably and fixedly embedded therein.

[0025] This application provides a SIM card fixing structure, in which a first waterproof rubber ring is provided at one end of the positioning member that abuts against the bottom wall of the SIM card slot. This improves the waterproof performance of the SIM card installation position, helps to reduce the probability that water will seep into the smart host from the card cover and damage the SIM card and its connection structure during the use of the corresponding smart host, thereby improving the stability of the corresponding smart host function and extending its service life.

[0026] In some embodiments, an abutment post is provided on one side of the card cover in the thickness direction, and the end of the abutment post opposite to the card cover abuts against the end of the positioning member located at the opening of the SIM card slot.

[0027] This application provides a SIM card fixing structure. On the one hand, the abutment post is used to press the positioning member tightly into the SIM card slot, thereby reducing the probability of the positioning member and the SIM card inside the SIM card slot detaching from the SIM card slot during use, thus ensuring good communication performance of the corresponding smart host. On the other hand, the abutment post is used to support the positioning member and the card cover, maintaining a preset gap between the positioning member and the card cover at all times, so as to avoid directly damaging the SIM card and its connection structure when the card cover is bumped, which helps to further extend the service life of the corresponding smart host, thereby further improving the user experience.

[0028] In some embodiments, a second waterproof groove is provided on the side of the card cover near the positioning member in the thickness direction. The second waterproof groove extends along the periphery of the card cover, and a second waterproof rubber ring is detachably and fixedly embedded therein.

[0029] This application provides a SIM card fixing structure. In practical applications, after the positioning component containing the SIM card is installed in the SIM card slot, the side of the card cover with the second waterproof rubber ring is pressed against the end face of the smart host located at the opening of the SIM card slot. After the card cover is locked onto the smart host, the second waterproof groove seals the gap between the card cover and the smart host, effectively preventing moisture from entering the smart host from the SIM card slot opening and damaging the SIM card and related structures. This effectively improves the waterproof effect of the corresponding smart host and further extends the service life of the corresponding smart host, helping to ensure user experience.

[0030] On the other hand, this application also provides a smart host, including:

[0031] The host unit, the SIM card, and any of the SIM card fixing structures described above;

[0032] The SIM card has a first spring clip on one side in the thickness direction, and the SIM card is detachably mounted on the positioning member of the SIM card fixing structure.

[0033] The main body of the host is provided with a SIM card slot, and the bottom surface of the SIM card slot is provided with a second spring for connecting the first spring.

[0034] The card cover is detachably covered by the SIM card slot opening through the connecting structure, so that after the positioning member slides and is embedded in the SIM card slot along the depth direction of the SIM card slot until the first spring contactes the second spring, the positioning member and the SIM card inside are stably limited in the SIM card slot.

[0035] Compared with the prior art, the SIM card fixing structure and smart host provided in this application have at least one of the following advantages:

[0036] 1. This application separates the positioning structure of the SIM card from the card cover, which significantly reduces the production difficulty of the SIM card fixing structure and the production cost of the corresponding smart host equipment while taking into account the user experience, thus effectively promoting cost reduction and efficiency improvement for enterprises.

[0037] 2. In this application, depending on the setting of the installation position, at least one waterproof form can be selected from waterproof protrusion, first waterproof rubber ring, and second waterproof rubber ring to achieve effective waterproofing of the corresponding smart host SIM card and its associated structure.

[0038] 3. In this application, it is preferable to open an installation groove on the periphery of the SIM card slot opening of the smart host, so that when the card cover is detachably installed on the host body, the card cover is embedded in the installation groove on the surface of the smart host. On the one hand, this helps to improve the flatness of the surface of the smart host, thereby reducing friction on the user's skin during wearing and improving the comfort of use; on the other hand, it also helps to further reduce the probability of dust, moisture, etc. entering the host body from the gap between the card cover and the host body and damaging the corresponding smart host, effectively extending the service life of the corresponding smart host.

[0053] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0054] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0055] In the smart host industry, the communication functions of smart host devices such as smartwatches require the installation of a SIM card. Currently, smart host devices on the market, such as smartwatches, typically use a mounting slot on their base plate to allow for detachable assembly of the SIM card and the host body. During assembly, the SIM card is fixedly embedded in the mounting slot on the base plate. After the base plate is secured to the back of the host body, the corresponding position of the mounting slot on the base plate corresponds to the SIM card slot position on the host body, ensuring stable contact between the pins of the SIM card and the corresponding pins on the bottom of the SIM card slot. However, this method, for small-sized smart host devices such as smartwatches, involves a small and complex SIM card mounting structure on its base plate, resulting in high production difficulty and cost, which is not conducive to energy conservation and cost reduction for enterprises.

[0056] In one embodiment, reference is made to the accompanying drawings. Figures 1 to 11This invention provides a SIM card fixing structure for stably installing a SIM card 100 into the SIM card slot 210 of a smart host device. By optimizing the installation and fixing method of the SIM card 100, the invention effectively reduces the production difficulty and cost of the corresponding smart host device, thereby promoting cost reduction and efficiency improvement for enterprises. It includes a positioning component 1 and a card cover 2. The positioning component 1 has an installation position 11, the shape of which is adapted to the shape of the SIM card 100 so that the SIM card 100 can be detachably installed. The shape of the positioning component 1 is adapted to the shape of the SIM card slot 210 on the host body 200. During assembly, the positioning component 1 can slide and embed itself in the SIM card slot 210 along the depth direction until the first spring 110 on the SIM card 100 stably contacts the corresponding second spring 310 on the bottom wall of the SIM card slot 210. The card cover 2 is located on one side of the positioning component 1 and is detachably connected to the host body 200 to detachably cover the opening of the SIM card slot 210, thereby stably limiting the positioning component 1 in the SIM card slot 210 to achieve stable installation of the SIM card 100 in the smart host device.

[0057] In one embodiment, based on the above embodiments, specifically referring to... Figure 2 , Figure 3 , Figure 7 and Figure 9 To facilitate the explanation of the technical solution, the accompanying drawings of this embodiment only show an application scenario where the SIM card slot 210 is generally rectangular; correspondingly, refer to... Figure 5 , Figures 6 to 8 The positioning element 1 is adapted to the SIM card slot 210 in a generally rectangular block shape. Of course, according to the stacking requirements of the internal circuits and structures of the smart host, the SIM card slot 210 and the positioning element 1 can be adapted to other shapes, as long as it does not affect the normal contact between the first spring 110 of the SIM card 100 and the second spring 310 in the SIM card slot 210. The implementation method of this application is not specifically limited in this respect. The technical solution of this application is specifically described with the positioning element 1 being generally rectangular block shape as an example.

[0058] Reference Figure 5 and Figure 6In this embodiment, the mounting position 11 is formed in the middle of the positioning member 1. It is used to limit the installation position of the SIM card 100 in the card holder 300 area at the bottom of the SIM card slot 210 after the positioning member 1 is embedded in the SIM card slot 210, thereby ensuring accurate engagement between the first spring 110 and the second spring 310. For this purpose, in this embodiment, the mounting position 11 is preferably configured as a mounting groove. The mounting groove is opened on one side of the positioning member 1 in the thickness direction, and its shape is adapted to the shape of the SIM card 100. This ensures that after the positioning member 1 is assembled into the SIM card slot 210, the side of the SIM card 100 with the first spring 110 completely abuts against the corresponding area of ​​the card holder 300, preventing the positioning member 1 from obstructing the first spring 110. Furthermore, in this embodiment, it is preferable that the SIM card 100 is slidably embedded in the mounting groove until the end facing away from the first spring 110 abuts against the bottom wall of the mounting groove; see reference. Figure 5 The SIM card 100 is slidably embedded in the mounting groove along the depth direction of the mounting groove, and can remain fixed relative to the mounting groove after sliding to the corresponding position; preferably, the connection between the SIM card 100 and the positioning member 1 is a tight-fit sliding connection. For example, the area of ​​the positioning member 1 corresponding to the inner wall of the mounting groove is made of soft silicone or other materials, so as to increase the friction between the SIM card 100 and the side wall of the mounting groove without damaging the SIM card 100.

[0059] Meanwhile, to facilitate the removal of the SIM card 100 from the installation position 11, refer to Figure 5 In this embodiment, preferably, the positioning member 1 has a through hole 12 in the thickness direction corresponding to the middle of the bottom wall of the mounting groove. In practical applications, when it is necessary to remove or replace the SIM card 100, the positioning member 1 is taken out from the SIM card slot 210, and the SIM card 100 is pushed out from the mounting groove opening through the through hole 12. In the embodiments of this application, the SIM card 100 can also be disengaged from the positioning member 1 by making a notch in the positioning member 1. For example, the notch is made on the side wall of the positioning member 1 at the end of the mounting groove opening, which penetrates the side wall of the mounting groove and communicates with the mounting groove opening. In practical applications, the user can push the SIM card 100 from the notch towards the mounting groove opening to disengage the SIM card 100 from the positioning member 1. Of course, this effect can also be achieved by setting up a toggle member, push-pull member, etc., which will not be described in detail in this application.

[0060] In another embodiment of this application, reference is made to Figure 6The mounting position 11 is configured as a mounting hole, which extends through the thickness direction of the positioning member 1. In practical applications, the SIM card 100 is slidably embedded in the mounting hole along the thickness direction of the positioning member 1, achieving detachable installation on the positioning member 1. To ensure stable contact between the first spring tab 110 of the SIM card 100 and the second spring tab 310 at the card holder 300, in practical applications, it is preferable that the positioning member 1 is first slidably embedded in the SIM card slot 210, then the SIM card 100 is inserted into the mounting hole of the positioning member 1, and then the SIM card 100 is pushed along the thickness direction of the positioning member 1 until the first spring tab 110 and the second spring tab 310 are in stable contact. Furthermore, to facilitate the quick embedding of the SIM card 100 into the mounting hole, preferably, referring to... Figure 6 and Figure 7 A guide slope 13 is provided on one end of the inner wall of the mounting hole corresponding to the opening of the SIM card slot 210.

[0061] In the embodiments of this application, the sidewall of the positioning member 1 slides in conjunction with the sidewall of the SIM card slot 210; considering the waterproofing issue of the corresponding smart host, refer to Figure 8 and Figure 9 Preferably, the sidewall of the positioning member 1 is formed with a waterproof protrusion 14 along its circumference. In this embodiment, the waterproof protrusion 14 is adapted to the shape of the positioning member 1 as an annular waterproof protrusion 14. In practical applications, when the positioning member 1 is embedded in the SIM card slot 210, the annular waterproof protrusion 14 abuts against the sidewall of the corresponding position of the SIM card slot 210 and slides and connects tightly with the sidewall of the SIM card slot 210 along the depth direction of the SIM card slot 210. In this way, while improving the waterproof performance of the smart host, the positioning member 1 can be detachably and stably installed relative to the smart host body 200. In this embodiment, the annular waterproof protrusion 14 is preferably set as a soft rubber waterproof protrusion 14. Furthermore, the annular waterproof protrusion 14 can be set in one ring on the sidewall of the positioning member 1, or multiple rings can be set parallel and spaced along the thickness direction of the positioning member 1 to ensure a good waterproof effect and stably reduce the probability of water entering the smart host from the gap between the positioning member 1 and the card holder 300 and damaging the SIM card 100 and its associated structures.

[0062] In another embodiment of this application, the waterproof structure can also be provided on the end wall of the positioning member 1; for example, a first waterproof rubber ring is provided at one end of the positioning member 1 that abuts against the card holder 300 in the thickness direction. Specifically, the first waterproof rubber ring is provided around the mounting position 11. For easy installation, a first waterproof groove is provided on the corresponding end wall of the positioning member 1, and the first waterproof rubber ring is detachably and fixedly embedded in the first waterproof groove. In practical applications, after the positioning member 1 is embedded in the SIM card slot 210 and the first spring 110 stably abuts against the second spring 310, the first waterproof rubber ring abuts against the bottom wall of the SIM card slot 210, thereby preventing moisture from seeping in from the gap between the positioning member 1 and the card holder 300 and damaging the SIM card 100 and its associated structure.

[0063] Of course, the waterproof structure can also be placed at point 2 of the cover to directly reduce the probability of moisture entering the smart host; refer to Figure 10 and Figure 11 A second waterproof groove 21 is provided on the side of the card cover 2 near the positioning member 1 in the thickness direction. The second waterproof groove 21 extends along the periphery of the card cover 2 to form an annular waterproof groove. A second waterproof rubber ring 3 is detachably and fixedly embedded in the second waterproof groove 21. In actual application, after the card cover 2 is placed over the opening of the SIM card slot 210, the second waterproof rubber ring 3 presses against the end wall of the host body 200 located at the opening of the SIM card slot 210, thereby reducing the probability that moisture will enter the SIM card slot 210 from the gap between the card cover 2 and the host body 200 and damage the SIM card 100 and its associated structures.

[0064] In actual production, at least one of the three waterproofing methods—annular waterproof protrusion 14, first waterproof rubber ring, and second waterproof rubber ring 3—can be set according to design requirements.

[0065] In addition, in this embodiment, a stop post is provided on the side of the card cover 2 near the positioning member 1 in the thickness direction. The end of the stop post away from the card cover 2 abuts against the end of the positioning member 1 located at the opening of the SIM card slot 210, so as to press the positioning member 1 tightly into the SIM card slot 210, reduce the probability of the positioning member 1 and the SIM card 100 inside it being dislodged from the SIM card slot 210 during use, thereby ensuring good communication performance of the corresponding smart host.

[0066] Furthermore, regarding the issue of removing the positioning member 1 from the SIM card slot 210, in this embodiment, it is preferable to provide a handle position at one end of the side wall of the positioning member 1 located at the opening of the SIM card slot 210; for example, the middle of both sides of the positioning member 1 is recessed inward to form a gripping space for fingers on the corresponding side walls, thereby forming a handle position; or, when an abutment post is provided on one side of the card cover 2 in the thickness direction, since there is a certain gap between the card cover 2 and the positioning member 1, a handle or pull ring for the user to hold can be formed on the side of the positioning member 1 near the card cover 2 to form a handle position; of course, other forms of handle positions can also be provided in the embodiments of this application, and this application does not specifically limit the form of the handle position.

[0067] The technical solution of this application will be further described in detail below, taking the application of the SIM card fixing structure to a specific smart host device as an example. In this regard, a smart host is provided, referring to... Figures 1 to 11 The SIM card fixing structure includes any of the above-described SIM card fixing structures, and also includes a SIM card 100 and a host body 200. The SIM card 100 has a first spring 110 on one side in the thickness direction. The SIM card 100 is detachably mounted on the positioning member 1 of the SIM card fixing structure. After the SIM card 100 is installed in the mounting position 11, its thickness direction is consistent with the thickness direction of the positioning member 1.

[0068] For the host unit 200, refer to Figure 9 The back of the device has a SIM card slot 210, and the bottom surface of the SIM card slot 210 has a card holder 300. The card holder 300 has a second spring 310 for connecting the first spring 110. During assembly, the SIM card 100 is first installed in the mounting position 11 of the positioning member 1, keeping the side of the first spring 110 on the SIM card 100 facing the SIM card slot 210. Then, the positioning member 1 is slid and embedded in the SIM card slot 210 along the depth direction of the SIM card slot 210 until the first spring 110 stably contacts the second spring 310. Alternatively, the positioning member 1 is first slid along the depth direction of the SIM card slot 210. The SIM card 100 is embedded in the SIM card slot 210, and the first spring 110 of the SIM card 100 is kept facing the SIM card slot 210. The SIM card 100 is slid and installed at the mounting position 11 of the positioning member 1 until the first spring 110 on the SIM card 100 is stably in contact with the corresponding second spring 310 at the bottom of the SIM card slot 210. Then, the SIM card slot 210 opening is covered by the card cover 2, and the card cover 2 is detachably connected to the host body 200 through the connecting structure. The positioning member 1 and the SIM card 100 inside it can be stably installed in the SIM card slot 210 of the host body 200.

[0069] In this embodiment, a positioning groove 220 is also provided on the periphery of the opening of the SIM card slot 210 on the host body 200. The positioning groove 220 is connected to the opening of the SIM card slot 210 and its range is larger than the range of the SIM card slot 210, so as to form a stepped groove structure on the back of the host body 200. In actual application, the card cover 2 is embedded in the positioning groove 220 to cover the opening of the SIM card slot 210.

[0070] In this embodiment, preferably, the side wall of the cover 2 and the side wall of the positioning groove 220 are tightly fitted and slidably connected. Furthermore, referring to... Figure 3 An operation port 230 is provided on the side wall of the positioning groove 220 on the main body 200. The operation port 230 penetrates the side wall of the positioning groove 220 and extends to the middle of the side wall of the SIM card slot 210. A gripping part 22 is formed on the edge of the card cover 2 corresponding to the operation port 230. When the card cover 2 is fastened to the opening of the SIM card slot 210, the gripping part 22 fills the operation port 230 to maintain the smoothness of the appearance of the main body 200 and improve its aesthetics. In actual application, the card cover 2 can be detached from the opening of the SIM card slot 210 by lifting the gripping part 22 from the operation port 230.
