Description

Card holder, card holder assembly and electronic device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on March 4, 2024, with application number 202420420251.4 and invention name “Card seat, card seat assembly and electronic device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of electronic equipment, and in particular to a card holder, a card holder assembly and an electronic device. Background Art

[0003] A subscriber identity module (SIM card) is installed in electronic devices such as mobile phones, smart watches, and tablet computers to identify the user and store user-related data and voice information.

[0004] A SIM card is typically installed in a tray, which then plugs into a card holder inside an electronic device to form a SIM card assembly. As electronic devices continue to increase in functionality, the space available for internal components is becoming increasingly limited. In related technologies, the relatively wide width of the SIM assembly presents a bottleneck in the overall layout of the electronic device, hindering the optimization of the overall architecture. Summary of the Invention

[0005] The present application provides a card socket, a card socket assembly and an electronic device, which are used to solve the problem of how to reduce the width of a SIM card assembly.

[0006] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0007] In a first aspect, an embodiment of the present application provides a card holder, which includes a base plate, a first side plate located on the same side of the base plate, a first limiting spring sheet and a second limiting spring sheet, and a first limiting portion. The first side plate, the first limiting spring sheet and the second limiting spring sheet are arranged in sequence along the first direction and are all connected to the base plate. The first limiting spring sheet, the second limiting spring sheet and the base plate are arranged to form a plug-in slot, which is used to plug in the card tray; the direction in which the card tray is inserted into the plug-in slot intersects with the first direction. The first limiting portion is connected to the base plate and is arranged with the first limiting spring sheet along the direction in which the card tray is inserted into the plug-in slot; the first limiting portion extends along the direction in which the card tray is inserted into the plug-in slot and arches toward the first side plate. The first limiting portion, the base plate and the first side plate are arranged to form an installation space, which is used to install the push rod.

[0008] The card holder provided in the embodiment of the present application forms an insertion slot for plugging in the card holder by making the bottom plate, the first limiting spring sheet and the second limiting spring sheet surround an installation space for installing the push rod. The first limiting portion and the first limiting spring sheet are arranged along the direction in which the card holder is inserted into the insertion slot. When the push rod is installed in the installation space, there is no need to reserve a large space between the push rod and the first limiting spring sheet for the stamping and bending mold for forming the first limiting portion and the first limiting spring sheet and the two bending fillets. It is only necessary to reserve the distance of the maximum deformation displacement of the first limiting spring sheet along the first direction during the insertion and removal of the card holder. This effectively reduces the width of the card holder along the first direction, thereby reducing the overall width of the SIM card assembly, and can release more installation space for other components of the electronic device using the card holder, which is beneficial to optimizing the layout of the entire electronic device and thereby improving the performance of the electronic device.

[0009] In addition, when the push rod slides along the direction in which the card holder is inserted into the insertion slot, the contact area between the first limiting portion and the push rod is small, which can reduce the friction between the two and is conducive to increasing the service life of both.

[0010] In some possible implementations of the first aspect, the first limiting portion is located behind the first limiting spring piece along the direction in which the card tray is inserted into the insertion slot. Thus, the portion of the first limiting portion near the first limiting spring piece, in an inclined direction relative to the first side plate, can prevent the card tray from being jammed against the first limiting portion during insertion, preventing smooth insertion. The portion of the first limiting portion away from the first limiting spring piece, in an inclined direction relative to the first side plate, can prevent the push rod from being jammed against the first limiting portion during assembly with the card holder, preventing smooth assembly.

[0011] In some possible implementations of the first aspect, the first position-limiting portion and the first position-limiting elastic piece are an integrated structure, which can reduce the difficulty of designing and processing the first position-limiting portion and the first position-limiting elastic piece.

[0012] In some possible implementations of the first aspect, the first limiting portion and the first limiting spring are spaced apart. This allows for greater flexibility in the placement of the first limiting portion, a smaller actual extension length, and a smaller space occupied by the first limiting portion.

[0013] In some possible implementations of the first aspect, the card holder further includes a first connecting plate. The first connecting plate extends from an edge of the first side plate distal from the bottom plate toward the first limiting spring, forming a wall of the aforementioned installation space. In this manner, the first connecting plate can be used to limit movement of the push rod relative to the card holder in a direction perpendicular to the bottom plate, thereby ensuring the overall reliability of the SIM card assembly.

[0014] In some possible implementations of the first aspect, the end of the first limiting portion away from the first limiting spring is located on a side of the first limiting spring facing away from the second limiting spring. This prevents the front end of the card tray from hitting the first limiting portion and becoming stuck during insertion into the card holder.

[0015] In some possible implementations of the first aspect, at least a portion of the first connecting plate is aligned with at least a portion of the first limiting portion along the direction in which the card holder is inserted into the insertion slot. This allows the push rod to be restricted from moving in the first direction, the direction in which the card holder is inserted into the insertion slot, and a direction perpendicular to the base plate at the same portion of the push rod. This prevents the push rod from wobbling during sliding, potentially scratching the limiting structure mating with it and reducing the service life of the card holder assembly. Furthermore, this facilitates removal of the card holder from the card holder.

[0016] In a second aspect, embodiments of the present application provide a card holder assembly comprising a card holder, a card tray, and a push rod. The card holder is any of the aforementioned implementations. The card tray is inserted into the aforementioned insertion slot. The push rod is mounted within the aforementioned installation space and is slidable relative to the card holder in the direction in which the card tray is inserted into the insertion slot.

[0017] Since the card holder assembly provided in the embodiment of the present application includes a card holder of any of the above implementation methods, the two can solve the same problem and achieve the same effect, and will not be repeated here.

[0018] In some possible implementations of the second aspect, the tray includes a first side surface and a second side surface, the first side surface facing the first limiting spring plate, the first side surface having a first engaging groove, the second side surface facing the second limiting spring plate, the second side surface having a second engaging groove. The first limiting spring plate includes a first connecting section, a first bending section, and a second connecting section connected in sequence, the first connecting section and the second connecting section both being connected to the bottom plate, the first bending section arching in a direction close to the first side surface and engaging in the first engaging groove. The second limiting spring plate includes a third connecting section, a second bending section, and a fourth connecting section connected in sequence, the third connecting section and the fourth connecting section both being connected to the bottom plate, the second bending section arching in a direction close to the second side surface and engaging in the second engaging groove.

[0019] In this way, the first limiting spring piece and the second limiting spring piece can not only clamp and fix the card tray after the card tray is inserted into the seat body, but also facilitate the removal of the card tray from the card seat to replace and repair the SIM card.

[0020] In some possible implementations of the second aspect, the card holder further includes a first surface facing away from the bottom plate, the first surface having a first groove and a second groove spaced apart along the direction in which the card holder is inserted into the plug-in slot. The first groove has a first groove sidewall facing away from the second groove, a second groove sidewall facing away from the second limiting spring sheet, and a third groove sidewall connected between the first groove sidewall and the second groove sidewall. From the first groove sidewall to the second groove sidewall, the third groove sidewall extends in a direction gradually away from the second groove; the position where the third groove sidewall meets the second groove sidewall is the first position. The second groove has a fourth groove sidewall facing away from the first groove and a fifth groove sidewall facing away from the second limiting spring sheet, and the position where the fourth groove sidewall meets the fifth groove sidewall is the second position. Along the direction in which the card holder is inserted into the plug-in slot, the bottom wall of the second connecting slot is located between the first position and the second position.

[0021] In this way, when the card tray is removed, the force acting on the front side groove side wall of the second card slot can be dispersed to the card tray part between the two SIM cards, and the card tray part between the front one of the first groove and the second groove and the second side surface, and the wall thickness of the card tray part between the groove side wall of the rear one of the first groove and the second groove and the groove wall of the second card slot can be as large as possible. Therefore, the strength of the card tray with this structural form is better, and the wall thickness of the card tray can be reduced while ensuring the strength of the card tray, thereby reducing the overall width of the SIM card assembly.

[0022] In some possible implementations of the second aspect, the card holder further includes a first surface facing away from the bottom plate, the first surface having a first groove and a second groove spaced apart along the direction in which the card holder is inserted into the plug-in slot. The first groove has a first groove sidewall facing away from the second groove, a second groove sidewall facing away from the first limiting spring sheet, and a third groove sidewall connected between the first groove sidewall and the second groove sidewall. From the first groove sidewall to the second groove sidewall, the third groove sidewall extends in a direction gradually away from the second groove; the position where the third groove sidewall meets the second groove sidewall is the first position. The second groove has a fourth groove sidewall facing away from the first groove and a fifth groove sidewall facing away from the first limiting spring sheet, and the position where the fourth groove sidewall meets the fifth groove sidewall is the second position. Along the direction in which the card holder is inserted into the plug-in slot, the bottom wall of the first connecting groove is located between the first position and the second position.

[0023] In this way, when the card tray is removed, the force acting on the front side groove side wall of the first snap-in groove can be dispersed to the card tray part between the two SIM cards, and the card tray part between the front one of the first groove and the second groove and the first side surface, and the wall thickness of the card tray part between the groove side wall of the rear one of the first groove and the second groove and the groove wall of the first snap-in groove can be as large as possible. Therefore, the strength of the card tray with this structural form is better, and the wall thickness of the card tray can be reduced while ensuring the strength of the card tray, thereby reducing the overall width of the SIM card assembly.

[0024] In some possible implementations of the second aspect, the location where the sidewall of the third slot meets the sidewall of the first slot is the third position. Along the direction of insertion of the card tray into the insertion slot, the second slot is located in front of the first slot, the bottom wall of the first engaging slot is located between the first and third positions, and the bottom wall of the second engaging slot is located between the first and third positions. This fully utilizes the structure of the card tray portion corresponding to the SIM card cut corner, ensuring the strength of the card tray and facilitating its narrowing design. It also prevents the card tray portion at the first and second engaging slots from being too thin, thereby reducing its strength.

[0025] In some possible implementations of the second aspect, the card holder includes a plastic structure and a metal frame, the metal frame being embedded within the plastic structure. The minimum wall thickness of the metal frame along a direction perpendicular to a second direction is a first thickness, the thickness of the metal frame along the second direction is a second thickness, and the first thickness is greater than or equal to 0.8 times the second thickness. The second direction is perpendicular to both the first direction and the direction in which the card holder is inserted into the insertion slot. In this way, the card holder has both good toughness and high strength, and will not scratch other structural components during insertion or removal. Furthermore, when the metal frame is thin, the yield rate of the metal frame formed by cutting the blank plate can be guaranteed, thereby ensuring the reliability of the card holder.

[0026] In some possible implementations of the second aspect, the card holder assembly further includes a stopper and a fifth connecting segment. Along the direction in which the card holder is inserted into the plug-in slot, the stopper is located on the rear side of the first side panel. The two ends of the stopper arranged along the first direction are respectively a first end and a second end, and the second end is located between the first end and the card holder; along the first direction, the distance between the first end and the card holder is greater than or equal to the distance between the push rod and the card holder, and the distance between the second end and the card holder is less than the distance between the push rod and the card holder. The fifth connecting segment is connected between the second end and the rear end of the push rod; the fifth connecting segment can cooperate with the first limiting portion to limit the movement of the push rod along the direction in which the card holder is inserted into the plug-in slot.

[0027] In this way, the cross-sectional area of ​​the stopper can be larger than that of the push rod, facilitating the push pin and push rod to cooperate in removing the card tray. Furthermore, when the push rod, via the toggle member, pushes the card tray in the removal direction to the card ejection state, the second stopper can contact or have a clearance with the fifth connecting section to limit the push rod from sliding further in the direction of inserting the card tray into the insertion slot, thereby ensuring the reliability of the card holder assembly.

[0028] In a third aspect, embodiments of the present application provide an electronic device comprising a housing and a card holder assembly. The housing has a card insertion hole. The card holder assembly is the card holder assembly described in any of the aforementioned implementations, wherein the card holder is disposed within the housing, and the card tray is inserted into the card holder through the card insertion hole.

[0029] Since the electronic device provided in the embodiment of the present application includes a card holder assembly of any of the above implementation methods, the two can solve the same problem and achieve the same effect, which will not be described in detail here.

[0053] In the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0054] In the embodiments of the present application, it should be understood that the directional terms mentioned, such as "up", "down", "left", "right", "inside", "outside", etc., are only references to the directions in the drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0055] In the embodiments of the present application, the terms "first", "second", "third", "fourth", "fifth", "sixth", "seventh", "eighth", and "ninth" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first", "second", "third", "fourth", "fifth", "sixth", "seventh", "eighth", and "ninth" may explicitly or implicitly include one or more of the features.

[0056] In the embodiments of the present application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0059] The present application provides an electronic device that can implement user identity recognition with the help of a SIM card. Specifically, the electronic device includes but is not limited to a mobile phone, a tablet computer, a smartwatch, a wireless landline phone, smart glasses, and a smart home intercom system.

[0060] Please refer to Figures 1 and 2 together. Figure 1 is a perspective view of an electronic device 100 provided in some embodiments of the present application, and Figure 2 is a schematic diagram of the exploded structure of the electronic device 100 shown in Figure 1. This embodiment is illustrative of the electronic device 100 as a foldable screen mobile phone. The electronic device 100 includes a housing 10, a SIM card assembly 20, and a foldable screen 30.

[0061] It should be understood that Figures 1 and 2 schematically illustrate some components of the electronic device 100, and the shapes and sizes of these components are not limited by Figures 1 and 2. Moreover, in addition to these components, the electronic device 100 also includes internal electronic components such as a battery, camera, speaker, vibration motor, etc. When the electronic device 100 is another product, the electronic device 100 may not include the foldable screen 30.

[0062] The housing 10 is used to protect the foldable screen 30 and internal electronic components. In the embodiment shown in Figures 1 and 2, the housing 10 includes a first housing 11 and a second housing 12. In other embodiments, when the electronic device 100 is other products, the electronic device 100 may also include one housing or three or more housings, which is not specifically limited in this application.

[0063] The first housing 11 and the second housing 12 are used to support the folding screen 30. Specifically, please continue to refer to Figures 1 and 2. The folding screen 30 includes a first folding screen portion 31 and a second folding screen portion 32. The first housing 11 supports the first folding screen portion 31, and the second housing 12 supports the second folding screen portion 32.

[0064] Please refer to Figure 3, which is a schematic diagram of the cross-sectional structure of the electronic device 100 shown in Figure 1 at line AA. The first shell 11 includes a first front shell 111 and a first back cover 112. The first front shell 111 includes a first middle plate 1111 and a first frame 1112 arranged on the edge of the first middle plate 1111. The first back cover 112 is located on the side of the first front shell 111 away from the first folding screen part 31 and is fixed to the first frame 1112. A first accommodating cavity C1 is formed between the first front shell 111 and the first back cover 112. The first accommodating cavity C1 is used to accommodate electronic components such as circuit boards, batteries, vibration motors, and speaker modules.

[0065] Similarly, please continue to refer to Figure 3. The second shell 12 includes a second front shell 121 and a second back cover 122. The second front shell 121 includes a second middle plate 1211 and a second frame 1212 provided at the edge of the second middle plate 1211. The second back cover 122 is located on the side of the second front shell 121 away from the second folding screen portion 32 and is fixed to the second frame 1212. A second accommodating cavity C2 is formed between the second front shell 121 and the second back cover 122. The second accommodating cavity C2 is used to accommodate electronic components such as circuit boards, batteries, and camera modules.

[0066] Please refer to Figures 2 and 3 together. The shell 10 also includes a hinge mechanism 13. The first shell 11 and the second shell 12 are rotatably connected via the hinge mechanism 13, so that the folding screen 30 can be folded from the unfolded state shown in Figures 1 to 3 to the folded state.

[0067] When the folding screen 30 is in the unfolded state, please continue to refer to Figure 3. The angle θ between the first folding screen part 31 and the second folding screen part 32 on the display side is approximately 180°, which can achieve a large-screen display to provide users with richer information and bring users a better user experience. When the folding screen 30 is in the folded state, the angle θ can be approximately 360°, that is, the electronic device 100 is an outward-folding folding screen mobile phone. When the folding screen 30 is in the folded state, the angle θ can also be approximately 0°, that is, the electronic device 100 is an inward-folding folding screen mobile phone. In this way, the folding screen mobile phone is smaller in size and more convenient to carry. Among them, the display side refers to the side to which the display surface of the folding screen 30 faces. When the folding screen 30 is in the unfolded state and working, the user can view the image or video displayed on the folding screen 30 from the display side.

[0068] When the foldable screen 30 is in the unfolded state, the thickness of the foldable screen mobile phone is a first thickness h; when the foldable screen 30 is in the folded state, the thickness of the foldable screen mobile phone is a second thickness H; the second thickness H is approximately twice the first thickness h. Based on this, in order to improve portability and hand feel, foldable screen mobile phones are increasingly pursuing thinner shapes in the unfolded state to reduce the thickness in the folded state. Therefore, the volume of the aforementioned first accommodating cavity C1 and the volume of the second accommodating cavity C2 are also getting smaller and smaller. Therefore, the layout of the components in the first accommodating cavity C1 and the second accommodating cavity C2 also needs to be optimized to ensure the performance of the entire electronic device 100.

[0069] Please refer to Figure 4, which is a partial enlarged view of point B in Figure 3. The housing 10 is provided with a card insertion hole 10a, which runs through both the inner and outer sides of the housing 10. In the embodiment shown in Figures 3 and 4, the card insertion hole 10a is provided in the first frame segment K, which is located on the first frame 1112. The first frame segment K forms the end of the first housing 11 away from the hinge mechanism 13, and the length direction of the first frame segment K is parallel to the rotation axis of the hinge mechanism 13. The card insertion hole 10a connects the external space of the first housing 11 with the first accommodating chamber C1. In some other embodiments, the length direction of the first frame segment K can also be perpendicular to the rotation axis of the hinge mechanism 13. In still other embodiments, the card insertion hole 10a can also be provided in other parts of the housing 10, such as the first back cover 112, the second frame 1212, and the second back cover 122, etc., which are not specifically limited here.

[0070] The SIM card assembly 20 is positioned within the card insertion slot 10a. Please refer to Figures 4-6 . Figure 5 illustrates a schematic diagram of the SIM card assembly 20 of the electronic device 100 shown in Figure 4 , while Figure 6 illustrates the SIM card assembly 20 shown in Figure 5 viewed from another direction. The SIM card assembly 20 includes a card holder assembly 21 and a SIM card 22. The card holder assembly 21 includes a card holder 211, a card tray 212, and a card ejection device 213.

[0071] The card holder 211 is disposed within the housing 10. Optionally, referring to Figure 4 , the card holder 211 is disposed within the aforementioned first accommodating cavity C1. Specifically, the card holder 211 can be secured to the circuit board 40 within the first accommodating cavity C1 and electrically connected to the circuit board 40 via the card holder terminals 2112. The SIM card 22 is disposed on the card tray 212. The card tray 212 is inserted into the card holder 211 via the card insertion hole 10a, so that the SIM card terminals 221 on the SIM card 22 contact and electrically connect with the card holder terminals 2112. This in turn electrically connects the card holder 211 to the circuit board 40 to access user identity information. Together with the first frame segment K, the card holder 211 forms a complete midframe appearance.

[0072] The card tray 212 is inserted into the insertion slot of the card holder 211. It should be noted that the card tray 212 has a direction for insertion into the insertion slot. The direction of insertion of the card tray 212 into the insertion slot refers to the direction of movement of the card tray 212 during insertion into the insertion slot of the card holder 211 via the card insertion hole 10a. The direction of insertion of the card tray 212 into the insertion slot is limited by the card insertion hole 10a and the space within the card holder 211 for accommodating the card tray 212. Based on this, to facilitate the description of the various embodiments below, the direction of insertion of the card tray 212 into the insertion slot is defined as the +X-axis direction, and the direction of the card tray 212 (the direction opposite to the insertion direction into the insertion slot) is defined as the -X-axis direction. Based on this, the direction parallel to the plane of the card tray 212 and perpendicular to the direction in which the card tray 212 is inserted into the insertion slot is defined as the first direction. The first direction is the Y-axis direction, that is, the first direction intersects the direction in which the card tray 212 is inserted into the insertion slot; the direction perpendicular to the plane of the card tray 212 is defined as the second direction. The second direction is the Z-axis direction, that is, the first direction, the second direction, and the direction in which the card tray 212 is inserted into the insertion slot are perpendicular to each other. Of course, the insertion direction of the card tray 212 can also be positioned as other axial directions, which is not specifically limited here. In some other embodiments, the first direction may not be perpendicular to the direction in which the card tray 212 is inserted into the insertion slot.

[0073] Continuing to refer to Figures 5 and 6, the card holder 211 includes a base 2111 and a card holder terminal (not shown in Figures 5 and 6), which is fixed relative to the base 2111. The base 2111 includes a bottom plate 21111, a first side plate 21112, a second side plate 21113, a first limiting spring piece 21114, a second limiting spring piece 21115, and a second limiting portion 21116. The bottom plate 21111 has a third surface 21111a. The first side plate 21112, the second side plate 21113, the first limiting spring 21114, the second limiting spring 21115, and the second limiting portion 21116 are all located on the side facing the third surface 21111a. That is, the first side plate 21112, the second side plate 21113, the first limiting spring 21114, the second limiting spring 21115, and the second limiting portion 21116 are all located on the same side of the bottom plate 21111. The first side plate 21112, the first limiting spring 21114, and the second limiting spring 21115 are arranged in sequence along the Y-axis and are all connected to the bottom plate 21111. The first limiting spring 21114, the second limiting spring 21115, and the bottom plate 21111 define a slot for receiving the card tray 212.

[0074] Two opposite ends of the first limiting spring piece 21114 are connected to the bottom plate 21111 , and a portion of the first limiting spring piece 21114 is arched and bent toward the second limiting spring piece 21115 .

[0075] The second side panel 21113 can include sub-side panels spaced apart along the X-axis. A second retaining spring 21115 is located between the two sub-side panels. Opposite ends of the second retaining spring 21115 are connected to the bottom panel 21111. A portion of the second retaining spring 21115 is arched and bent toward the first retaining spring 21114. In some examples, the two ends of the second retaining spring 21115 along the X-axis can be coplanar with the second side panel 21113 to reduce the overall width of the base 2111 along the Y-axis. In other embodiments, the base 2111 may not include the second side panel 21113.

[0076] The second limiting portion 21116 is connected to the bottom plate 21111 and is located between the first limiting spring 21114 and the first side plate 21112. The second limiting portion 21116, the first side plate 21112, and the first limiting spring 21114 are all spaced apart. The second limiting portion 21116, the bottom plate 21111, and the first side plate 21112 define an installation space for accommodating a push rod 2131, described below. In the embodiment shown in Figures 5 and 6, there are two second limiting portions 21116, which are spaced apart along the X-axis to provide a more reliable limiting and guiding effect for the push rod 2131. In other embodiments, the number of second limiting portions 21116 can also be three or more, with the plurality of second limiting portions 21116 spaced apart along the X-axis.

[0077] Continuing with Figures 5 and 6, the card tray 212 is removably inserted into the base 2111 and into the aforementioned insertion slot, and is secured thereto by a first retaining spring 21114 and a second retaining spring 21115. Specifically, the card tray 212 includes a first side 212a and a second side 212b. The first side 212a faces the first retaining spring 21114 and defines a first retaining slot 212a1. The second side 212b faces the second retaining spring 21115 and defines a second retaining slot 212b1. The bent portion of the first retaining spring 21114 retains the first retaining slot 212a1, while the bent portion of the second retaining spring 21115 retains the second retaining slot 212b1.

[0078] On this basis, the card tray 212 is provided with a groove, which forms a slot for installing the SIM card 22. In the embodiment shown in Figures 5 and 6, the card tray 212 has two slots. Specifically, the card tray 212 further has a first surface 212c and a second surface 212d spaced apart along the Z-axis, with the first surface 212c facing away from the third surface 21111a. The first surface 212c has a first groove 212c1 and a second groove 212c2 spaced apart along the X-axis. Based on this, there are two SIM cards 22, each accommodated in the first groove 212c1 and the second groove 212c2, respectively. In this way, the electronic device 100 can meet dual-SIM card requirements, allowing users to communicate using two mobile phone numbers simultaneously on a single phone. In other embodiments, the number of grooves on both the SIM card 22 and the card tray 212 can also be one, three, or more.

[0079] Based on the above, please continue to refer to Figures 5 and 6. The card ejection device 213 includes a push rod 2131 and a toggle member 2132. The push rod 2131 is installed and fitted within the aforementioned installation space, that is, the push rod 2131 is accommodated and fitted between the second limit portion 21116 and the first side plate 21112. The push rod 2131 can slide relative to the card holder 211 along the X-axis direction. Furthermore, the toggle member 2132 is located at the front side of the card holder 212 and can rotate relative to the card holder 211 about the first axis L1. The toggle member 2132 includes a first swing arm portion 21321 and a second swing arm portion 21322 located on opposite sides of the first axis L1. Along the direction in which the card holder 212 is inserted into the insertion slot (the +X-axis direction), the first swing arm portion 21321 is located at the front side of the card holder 212, and the second swing arm portion 21322 is movably connected to the front end of the push rod 2131.

[0080] Please continue to refer to Figure 5 and Figure 1 . A pinhole 10b is also provided on the first frame segment K. Along the insertion direction (+X-axis direction) of the card tray 212, the pinhole 10b is located on the rear side of the push rod 2131 and is coaxial with the push rod 2131. During the card removal process, an ejector passes through the pinhole 10b and presses against the push rod 2131, driving the push rod 2131 forward in the direction (+X-axis direction) in which the card tray 212 is inserted into the insertion slot. This pushes the second swing arm 21322, causing the second swing arm 21322 to rotate about the first axis L1 in direction a1, while the first swing arm 21321 rotates in direction a2, thereby pushing the card tray 212 out along the removal direction (-X-axis direction) of the card tray 212, thereby facilitating replacement and repair of the SIM card 22.

[0081] Contrary to the above process, during the card insertion process, when the card tray 212 is inserted into the card holder 211 through the card insertion hole 10a along the direction of its insertion into the insertion slot (+X axis direction), the first swing arm part 21321 can be pushed to rotate along the direction a3, thereby causing the second swing arm part 21322 to rotate along the direction a4 to push the push rod 2131 to move a certain distance along the disassembly direction of the card tray 212 (-X axis direction), thereby realizing the reset of the push rod 2131 to facilitate the next card removal operation.

[0082] Please refer to Figures 5 and 7 , which is a partial structural schematic diagram of the SIM card assembly 20 shown in Figure 5 as viewed from the Z-axis direction. In the embodiments shown in Figures 5 and 7 , the portion of the first retaining spring 21114 connected to the base plate 21111 and the second retaining portion 21116 are disposed relative to each other along the Y-axis. Therefore, the overall width of the card holder assembly 21 along the Y-axis is defined by the width of the card tray 212, the thickness of the first side plate 21112, the thickness of the second retaining portion 21116, the thickness of the first retaining spring 21114, the thickness of the second retaining spring 21115, the thickness of the push rod 2131, the clearance between the card tray 212 and the first retaining spring 21114, the clearance between the card tray 212 and the second retaining spring 21115, and the distance between the first retaining spring 21114 and the second retaining portion 21116. While ensuring the strength of each structural component, the thickness of the first side plate 21112, the thickness of the second limiting spring piece 21115, the thickness of the second limiting portion 21116, the thickness of the first limiting spring piece 21114, and the thickness of the push rod 2131 cannot be further reduced.

[0083] In some examples, the card holder 211 can be a metal structure with an integrated structure. In this way, the seat body 2111 can not only install and fix the card tray 212, but also shield electromagnetic wave signals to prevent electromagnetic interference between the SIM card assembly 20 and other electronic components of the electronic device 100. Based on this, the first limiting spring 21114 and the second limiting portion 21116 can be formed by a stamping and bending process. Therefore, the distance between the first limiting spring 21114 and the second limiting portion 21116 must be greater than or equal to the maximum deformation displacement of the first limiting spring 21114 during the card insertion and ejection process. In addition, sufficient avoidance space must be reserved for the stamping and bending die to achieve a certain bending radius. This avoidance space and the bending radius of the process restrict the reduction of the width of the card holder 211. Therefore, the overall width of the card holder 211 is relatively large, which in turn leads to a larger overall width of the SIM assembly 20, restricting the size of other components inside the electronic device 100. For example, it restricts the size of the battery, affecting the battery life of the entire electronic device 100. For example, it restricts the size of the speaker module, affecting the low-frequency performance and loudness of the speaker module.

[0084] Please refer to Figures 5 and 8. Figure 8 is a schematic diagram of the structure of the card tray 212 of the SIM card assembly 20 shown in Figure 5 as viewed from the Z-axis direction. The first engaging slot 212a1 includes a ninth slot sidewall 212a11, a first slot bottom wall 212a12, and a sixth slot sidewall 212a13, which are sequentially connected along the direction in which the card tray 212 is inserted into the slot (the +X-axis direction). The sixth slot sidewall 212a13 is located in front of the ninth slot sidewall 212a11. The second engaging slot 212b1 includes a seventh slot sidewall 212b11, a second slot bottom wall 212b12, and an eighth slot sidewall 212b13. The eighth slot sidewall 212b13 is located in front of the seventh slot sidewall 212b11.

[0085] In the embodiments shown in Figures 5 and 8 , when there are two SIM cards 22, along the direction in which the card tray 212 is inserted into the insertion slot (the +X-axis direction), the sixth slot sidewall 212a13 and the eighth slot sidewall 212b13 are both located on the front side of the second slot 212c2, facing away from the first slot 212c1. Because the sixth slot sidewall 212a13 and the eighth slot sidewall 212b13 are the primary force-bearing surfaces during card removal, it is necessary to maximize the wall thickness of at least the card tray portion in front of the first engaging slot 212a1 and the card tray portion in front of the second engaging slot 212b1 along the Y-axis to ensure the strength of the card tray 212. Consequently, the card tray 212 is relatively wide, which in turn results in a relatively wide overall width for the SIM assembly 20.

[0086] To address the above issues, please refer to Figure 9, which is a schematic diagram of the structure of the SIM card assembly 20 as viewed from the Z-axis direction according to another embodiment of the present application. In the embodiment shown in Figure 9, the second limiting portion 21116, which is opposite the connection between the first limiting spring 21114 and the base plate 21111, is removed. Although the push rod 2131 can still be limited by the second limiting portion 21116 on the front side of the first limiting spring 21114, the push rod 2131 will wobble during the sliding process, making it difficult to remove the card tray 212 for repair or replacement of the SIM card 22.

[0087] Please refer to Figures 10-12. Figure 10 is another schematic diagram of the structure of the SIM card assembly 20 of the electronic device 100 shown in Figure 4. Figure 11 is a schematic diagram of the structure of the SIM card assembly 20 shown in Figure 10 as viewed from another direction. Figure 12 is an exploded schematic diagram of the SIM card assembly 20 shown in Figure 11. The SIM card assembly 20 includes a card holder assembly 21 and a SIM card 22. The card holder assembly 21 includes a card holder 211, a card tray 212, and a card ejection device 213.

[0088] Please refer to Figures 10, 12, and 13. Figure 13 is a schematic diagram of the partial structure of the SIM card assembly 20 shown in Figure 10 as viewed from the Z-axis direction. In the embodiments shown in Figures 12 and 13, the card holder 211 includes a holder body 2111 and holder terminals 2112. The structure of the card holder 211 is similar to that of the card holder 2111 in the embodiment shown in Figure 5, except that the holder terminals 2112 include an insulating bracket 21121 and conductive terminals 21122 fixed to the insulating bracket 21121. The insulating bracket 21121 can be fixed to the holder body 2111 or to the circuit board 40. The conductive terminals 21122 can be spring-type terminals that are fixed to the circuit board 40 by welding to achieve electrical connection with the circuit board 40.

[0089] The first position-limiting spring piece 21114 includes a first connecting section 21114a, a first bent section 21114b, and a second connecting section 21114c, which are connected in sequence. The first connecting section 21114a and the second connecting section 21114b are respectively connected to the bottom plate 21111. The first bent section 21114b arches toward the first side surface 212a and engages with the first engaging groove 212a1. The second position-limiting spring piece 21115 includes a third connecting section 21115a, a second bent section 21115b, and a fourth connecting section 21115c, which are connected in sequence. The third connecting section 21115a and the fourth connecting section 21115b are respectively connected to the bottom plate 21111. The second bent section 21115b arches toward the second side surface 212b and engages with the second engaging groove 212b1.

[0090] In some examples, the first limiting spring piece 21114 and the second limiting spring piece 21115 are in the form of sheets, and the first limiting spring piece 21114 and the second limiting spring piece 21115 can be integrally formed with the bottom plate 21111 by a stamping and bending process. In other examples, the first limiting spring piece 21114 and the second limiting spring piece 21115 can also be fixed to the bottom plate 21111 by welding or clamping.

[0091] In this way, the first limiting spring piece 21114 and the second limiting spring piece 21115 can not only fix the card tray 212 after the card tray 212 is inserted into the base 2111, but also facilitate the removal of the card tray 212 from the card base 211 to replace and repair the SIM card 22.

[0092] Please refer to Figures 12-14. Figure 14 is a partial enlarged view of point C in Figure 13. The holder 211 also includes a first stopper 21117, which is connected to the bottom plate 21111 and aligned with the first stopper spring 21114 along the X-axis. In the embodiment shown in Figures 12-14, the first stopper 21117 is located behind the first stopper spring 21114. The first stopper 21117 extends along the X-axis and arches toward the first side plate 21112.

[0093] Specifically, the first limiting portion 21117 includes a first extension section 21117a and a second extension section 21117b connected to each other. Along the insertion direction (+X-axis direction) of the card tray 212, the second extension section 21117b is located behind the first extension section 21117a. That is, the first extension section 21117a gradually approaches the first side plate 21112 from its end closest to the first limiting spring 21114 to its end closest to the first limiting spring 21114. The second extension section 21117b gradually approaches the first side plate 21112 from its end closest to the first limiting spring 21114 to its end closest to the first limiting spring 21114. Thus, the first limiting portion 21117, the bottom plate 21111, and the first side plate 21112 define an installation space within which the push rod 2131 is mounted. This installation space is used to mount the push rod 2131.

[0094] In some examples, the first limiting portion 21117 can be in the form of a sheet perpendicular to the bottom plate 21111, and the front end of the first extension section 21117a of the first limiting portion 21117 can be connected to the bottom plate 21111. Specifically, the first limiting portion 21117 can be integrally formed with the bottom plate 21111 by a stamping process. In other examples, the first limiting portion 21117 can also be fixed to the third surface 21111a of the bottom plate 21111 by welding or clamping.

[0095] In this way, by arranging the first limiting portion 21117 and the first limiting spring piece 21114 along the X-axis direction, there is no need to reserve a large space between the push rod 2131 and the first limiting spring piece 21114 for the stamping and bending mold and the two bending radii. It is only necessary to reserve the distance of the maximum deformation displacement of the first limiting spring piece 21114 during the insertion and removal of the card holder 212. This effectively reduces the width of the card holder 211 along the Y-axis direction, and thus reduces the overall width of the SIM card assembly 20, which can release more installation space for other components of the electronic device 100, and is conducive to optimizing the layout of the entire electronic device 100, thereby improving the performance of the electronic device 100.

[0096] In addition, when the push rod 2131 slides along the X-axis direction, the contact area between the first limiting portion 21117 and the push rod 2131 is small, which can reduce the friction between the two and is beneficial to improving the service life of the two.

[0097] In addition, when the first limiting portion 21117 is located on the rear side of the first limiting spring piece 21114, the first extension section 21117a of the first limiting portion 21117 relative to the inclined direction of the first side plate 21112 can prevent the front end of the card holder 212 from hitting the first limiting portion 21117 during the insertion process and getting stuck, and the second extension section 21117b relative to the inclined direction of the first side plate 21112 can prevent the front end of the push rod 2131 from hitting the first limiting portion 21117 and getting stuck, and failing to be smoothly assembled, during the process of assembling the push rod 2131 to the card holder 211.

[0098] Based on the above, please continue to refer to Figures 12 and 14. The first limiting portion 21117 and the first limiting spring piece 21114 are an integral structure. Specifically, the first extension section 21117a of the first limiting portion 21117 can be connected to the edge of the first limiting spring piece 21114. In some examples, the first limiting portion 21117, the base plate 21111, and the first limiting spring piece 21114 can be an integral structure. The first limiting portion 21117 and the first limiting spring piece 21114 are formed by first cutting a cantilever in the blank of the base plate 21111 and then using a stamping and bending process to form the first limiting portion 21117 and the first limiting spring piece 21114. In this way, the design and processing difficulty of the first limiting portion 21117 and the first limiting spring piece 21114 can be reduced.

[0099] In other embodiments, please refer to Figure 15 , which is a schematic diagram of the structure of the SIM card assembly 20 provided in other embodiments of the present application as viewed from the Z-axis. The first limiting portion 21117 can also be spaced apart from the first limiting spring 21114. This allows for greater flexibility in the placement of the first limiting portion 21117, and the extended lengths of the first extension section 21117a and the second extension section 21117b can be reduced, resulting in a smaller space occupied by the first limiting portion 21117. In yet other embodiments, further referring to Figure 15 , the first limiting portion 21117 can also be located in front of the first limiting spring 21114, or at a position opposite the bent portion of the first limiting spring 21114, thereby similarly reducing the width of the SIM card assembly 20.

[0100] Based on the above, referring back to FIG. 14 , the end of the second extension section 21117b that is remote from the first extension section 21117a is located on the side of the first limiting spring 21114 that faces away from the second limiting spring 21115. That is, the end of the first limiting portion 21117 that is remote from the first limiting spring 21114 is located on the side of the first limiting spring 21114 that faces away from the second limiting spring 21115. This prevents the front end of the card tray 212 from hitting the second extension section 21117b during insertion into the card holder 211, causing it to become stuck and unable to be inserted smoothly.

[0101] Referring to Figures 10 and 14 , the base 2111 further includes a first connecting plate 21118 extending from an edge of the first side plate 21112 away from the bottom plate 21111 toward the first position-limiting spring 21114. The first connecting plate 21118 forms a wall panel for mounting the push rod 2131. The first connecting plate 21118 can be used for soldering to the circuit board 40 and also for limiting the movement of the push rod 2131 along the Z-axis. This allows the first connecting plate 21118 to serve two different functions, reducing the design and manufacturing complexity of the base 2111. In the embodiment shown in Figures 10 and 14 , multiple first connecting plates 21118 are provided to ensure reliable attachment to the circuit board 40 and reliable positioning of the push rod 2131. Furthermore, other components of the base 2111 (such as the second side plate 21113) can also be provided with connecting plates for soldering to the circuit board 40.

[0102] Based on the above, referring to Figure 14 , along the X-axis, at least a portion of the first connecting plate 21118 is aligned with at least a portion of the first limiting portion 21117. This arrangement limits the movement of the push rod 2131 along the X-, Y-, and Z-axes at the same location. This prevents the push rod 2131 from wobbling during sliding, potentially scratching the limiting structure that it interfaces with, and thus reducing the service life of the card holder assembly 211. Furthermore, this arrangement facilitates removal of the card tray 212 from the card holder 211.

[0103] Based on the above, please refer to Figures 13, 16, and 17. Figure 16 is a schematic diagram of the structure of the SIM card assembly 20 shown in Figure 13 in the ejected state, and Figure 17 is a partial enlarged view of point D in Figure 16. The card ejection device 213 also includes a stopper 2133 and a fifth connecting section 2134. The stopper 2133 is located on the rear side of the first side panel 21112, along the direction in which the card tray 212 is inserted into the insertion slot. The stopper portion 2133 includes a first end 21331 and a second end 21332 arranged along the Y-axis. Along the Y-axis, the first end 21331 is located on the side of the first side plate 21112 facing away from the first limiting spring 21114, and the second end 21332 is located on the side of the push rod 2131 facing away from the first side plate 21112. In other words, the second end 21332 is located between the first end 21331 and the tray 212. The distance between the first end 21331 and the tray 212 is greater than or equal to the distance between the push rod 2131 and the tray 212, while the distance between the second end 21332 and the tray 212 is less than the distance between the push rod 2131 and the tray 212. Accordingly, the fifth connecting segment 2134 is connected between the second end 21332 and the rear end of the push rod 2131. In this way, the cross-sectional area of ​​the stop portion 2133 is larger than the cross-sectional area of ​​the push rod 2131 , which facilitates the abutment and cooperation between the ejector pin and the push rod 2131 .

[0104] On this basis, the second extension section 21117b of the first limiting portion 21117 is parallel to the fifth connecting section 2134, or the second extension section 21117b gradually moves away from the fifth connecting section 2134 from the end closest to the first side plate 21112 to the end farther away from the first side plate 21112. When the stopper 2133 contacts the first side plate 21112, a clearance exists between the fifth connecting section 2134 and the second extension section 21117b. The clearance is greater than or equal to 0 and less than or equal to 0.2 mm. Thus, when the push rod 2131 slides along the direction (+X axis) in which the card tray 212 is inserted into the insertion slot under the action of the ejector pin, the push rod 2131 pushes the card tray 212 toward the outside of the electronic device 100 via the toggle member 2132 to move to the card ejection state shown in FIG. 16 . At this time, the second side plate 21112 can work together with the second extension section 21117b to limit the push rod 2131 from continuing to slide along the direction (+X axis direction) in which the card tray 212 is inserted into the plug-in slot, thereby ensuring the reliability of the card holder assembly 21.

[0105] In some other embodiments, when the push rod 2131 slides in the direction (+X-axis direction) of the card tray 212 being inserted into the insertion slot under the action of the ejector, and the push rod 2131 pushes the card tray 212 toward the outside of the electronic device 100 to the card ejection state shown in FIG16 via the toggle member 2132, the stopper 2133 may also not contact the first side plate 21112, and the second extension section 21117b abuts against the fifth connecting section 2134 to limit the push rod 2131 from further sliding in the direction (+X-axis direction) of the card tray 212 being inserted into the insertion slot. In other words, the fifth connecting section 2134 can cooperate with the first limiting portion 21117 to limit the movement of the push rod 2131 in the direction of the card tray 212 being inserted into the insertion slot.

[0106] Based on the above, please refer to Figures 18 and 19. Figure 18 is a schematic diagram of the structure of the card tray 212 of the SIM card assembly 20 shown in Figure 10, and Figure 19 is a schematic diagram of the exploded structure of the card tray 212 shown in Figure 18. The card tray 212 includes a metal frame 2121 and a plastic structure 2122. The metal frame 2121 is embedded in the plastic structure 2122, and the shape of the metal frame 2121 matches the overall shape of the card tray 212. This ensures that the card tray 212 has both good toughness and high strength, and will not scratch the housing 10 and other structural components of the electronic device 100 during insertion or removal. Therefore, the card tray 212 has good reliability and a long service life. In some other embodiments, the card tray 212 can also be a plastic structural component. In still other embodiments, the card tray 212 can also be a metal structural component.

[0107] Specifically, the metal skeleton 2121 includes a first rib 21211 and a second rib 21212 extending along the Y-axis, and a third rib 21213 and a fourth rib 21214 extending along the X-axis. The first rib 21211 is located between the first groove 212c1 and the second groove 212c2, and the second rib 21212 is located on the side of the second groove 212c2 away from the first groove 212c1. The third rib 21213 is located on the same side of the first groove 212c1 and the second groove 212c2, and is connected to both the first rib 21211 and the second rib 21212; the fourth rib 21214 is located on the same side of the first groove 212c1 and the second groove 212c2, and is connected to the other end of the first rib 21211 and the other end of the second rib 21212. The third rib 21213 and the fourth rib 21214 extend away from one end of the second rib 21212 to the side of the first groove 212c1 facing away from the second groove 212c2.

[0108] Continuing with FIG18 , the width of the card tray 212 along the Y-axis is defined by the width of the SIM card 22, the wall thickness of the plastic structure 2122 between the metal frame 2121 and the first retaining spring 21114, the wall thickness of the plastic structure 2122 between the metal frame 2121 and the SIM card 22, and the clearance between the SIM card 22 and the card tray 212. Directly reducing the wall thickness of the metal frame 2121 compared to the card tray 212 in the embodiment shown in FIG8 reduces the strength of the card tray 212, thereby reducing the overall reliability of the SIM card assembly 20.

[0109] Based on this, please continue to refer to Figure 18. In the embodiment shown in Figure 18, along the direction in which the card tray 212 is inserted into the plug-in slot, the second groove 212c2 is located on the front side of the first groove 212c1, and the second groove 212c2 has a fourth groove side wall 212c21 extending along the Y-axis direction and a fifth groove side wall 212c22 extending along the X-axis direction. The fourth groove side wall 212c21 is back to the first groove 212c1, and the fifth groove side wall 212c22 is back to the second side surface 212b. The position where the fourth groove side wall 212c21 and the fifth groove side wall 212c22 are connected is the second position N. The first groove 212c1 includes a first groove sidewall 212c11 extending along the Y-axis, a second groove sidewall 212c12 extending along the X-axis, and a third groove sidewall 212c13 connecting the first groove sidewall 212c11 and the second groove sidewall 212c12. The third groove sidewall 212c13 extends gradually away from the second groove 212c2 from the first groove sidewall 212c11 to the second groove sidewall 212c12. The first groove sidewall 212c11 and the third groove sidewall 212c13 face away from the second groove 212c2, while the second groove sidewall 212c12 faces away from the second side surface 212b. The location where the third groove sidewall 212c13 meets the second groove sidewall 212c12 is a first position M.

[0110] On this basis, along the direction in which the card tray 212 is inserted into the insertion slot, the second slot bottom wall 212b12 and the first slot bottom wall 212a12 are located between the first position M and the second position N, that is, the bottom wall of the second engaging slot 212b1 and the bottom wall of the first engaging slot 212a1 are located between the first position M and the second position N. In this way, when the card tray 212 is removed, the force acting on the eighth slot side wall 212b13 and the sixth slot side wall 212a12 can be dispersed to the portion of the card tray between the two SIM cards 22, and the portion of the card tray between the second groove 212c2 and the first side surface 212a and the second side surface 212b. Therefore, this structural form of the card tray 212 has greater strength, and the wall thickness of the card tray 212 can be reduced while ensuring the strength of the card tray 212 in use, thereby reducing the overall width of the SIM card assembly 20.

[0111] Based on the above, along the direction in which the card tray 212 is inserted into the insertion slot, the location where the first slot side wall 212c11 and the third slot side wall 212c13 meet is the third position P, and the second slot bottom wall 212b12 and the first slot bottom wall 212a12 are located between the first position M and the third position P. That is, the bottom wall of the second engaging slot 212b1 and the bottom wall of the first engaging slot 212a1 are located between the first position M and the third position P. This not only fully utilizes the structure of the card tray portion corresponding to the cut corner of the SIM card 22, ensuring the strength of the card tray 212 and facilitating its narrowing design, but also prevents the metal frame 2121 at the first engaging slot 212a1 and the second engaging slot 212b1 from being too thin, thereby reducing the strength of the card tray 212. It should be noted that the bottom wall of the second snap-in groove 212b1 refers to the area in the second snap-in groove 212b1 with the largest distance from the second side surface 212b, and the bottom wall of the first snap-in groove 212a1 refers to the area in the first snap-in groove 212a1 with the largest distance from the first side surface 212a; in the embodiment shown in Figure 18, the bottom wall of the second snap-in groove 212b1 and the bottom wall of the first snap-in groove 212a1 are both planes. In some other embodiments, the bottom wall of the second snap-in groove 212b1 and the bottom wall of the first snap-in groove 212a1 may also be a straight line or a curve, and this application does not limit this.

[0112] In some other embodiments, the second slot sidewall 212c12 may also face away from the first side surface 212a, and the fifth slot sidewall 212c22 may face away from the first side surface 212a. In still other embodiments, along the direction in which the card tray 212 is inserted into the insertion slot, the first groove 212c1 may also be located in front of the second groove 212c2. When the second slot sidewall 212c12 faces away from the first side surface 212a and the fifth slot sidewall 212c22 faces away from the first side surface 212a, it is sufficient that the bottom wall of the first engaging groove 212a1 is located between the first position M and the second position N, and the second engaging groove 212b1 is not limited. When the second slot sidewall 212c12 faces away from the second side surface 212b and the fifth slot sidewall 212c22 faces away from the second side surface 212b, it is sufficient that the bottom wall of the second engaging groove 212b1 is located between the first position M and the second position N, and the first engaging groove 212a1 is not limited.

[0113] Based on the above, the minimum wall thickness of the metal skeleton 2121 along the direction perpendicular to the Z-axis is the first thickness, and the wall thickness along the Z-axis is the second thickness. The first thickness is greater than or equal to 0.8 times the second thickness of the metal skeleton 2121. Taking the thickness of the metal skeleton 2121 along the Z-axis as 0.4 mm as an example, the minimum wall thickness of the metal skeleton 2121 along the direction perpendicular to the Z-axis can be 0.32 mm, 0.34 mm, 0.36 mm, 0.38 mm, 0.4 mm, 0.42 mm, 0.44 mm, 0.46 mm, and 0.48 mm, etc. In this way, when the thickness of the metal skeleton 2121 is relatively thin, the yield rate of the metal skeleton 2121 cut from the blank plate can be guaranteed, thereby ensuring the reliability of the tray 212.

[0114] Taking the case where the material thickness of the base 2111 is 0.15 mm and the thickness of the metal skeleton 2121 of the card tray 212 along the Z-axis direction is 0.4 mm as an example, through the structural design of the aforementioned first limiting portion 21117, the width of the card holder 211 can be reduced by about 0.5 mm, and through the position design of the aforementioned first card slot 212a1 and the second card slot 212b1, the width of the card tray 212 can be reduced by about 0.3 mm. Therefore, the cumulative width of the card holder assembly 21 of the SIM card assembly 20 shown in Figure 10 can be reduced by about 0.8 mm.

[0115] Please refer to Figures 20a, 20b, and 21. Figure 20a is a schematic diagram of the applied torsional torque during a strength test of the card holder 212 shown in Figure 8, and Figure 20b is a schematic diagram of the applied torsional torque during a strength test of the card holder 212 shown in Figure 18. Figure 21 is a graph showing the relationship between the torsional angle generated by the card holder 212 in Figures 20a and 20b and the required torsional torque. S1 is the test curve for the card holder 212 in Figure 20a, and S2 is the relationship curve for the card holder 212 in Figure 20b. As can be seen from Figure 21, due to the design of the position of the first engaging slot 212a1 and the second engaging slot 212b1, even when the width of the card holder 212 is reduced, the strength of the card holder 212 shown in Figure 16 is still greater than that of the card holder 212 shown in Figure 8. Therefore, while ensuring the reliability of the card holder assembly 21, it also helps improve the performance of the entire electronic device 100.
