Description

Technical Field

[0001] This application relates to the technical field of electronic devices, and particularly to a card holder, a card holder assembly, and an electronic device. Background Art

[0002] In electronic devices such as mobile phones, smartwatches, and tablet computers, a subscriber identity module (SIM card) is installed to identify the user's identity, store user-related data, and voice information.

[0003] The SIM card is usually installed on a card tray, and the card tray is inserted into a card holder inside the electronic device to form a SIM card assembly. With the continuous increase in the functions of electronic devices, the internal layout space of electronic devices is becoming more and more tense. In related technologies, the width of the SIM card assembly is relatively large, which becomes a bottleneck in the overall layout of the electronic device and is not conducive to optimizing the overall architecture layout. Summary of the Utility Model

[0004] This application provides a card holder, a card holder assembly, and an electronic device, which are used to solve the problem of how to reduce the width of the SIM card assembly.

[0005] To achieve the above object, the embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, an embodiment of this application provides a card holder, which includes a bottom plate, a first side plate, a first limiting elastic piece, and a second limiting elastic piece on the same side of the bottom plate, and a first limiting portion. The first side plate, the first limiting elastic piece, and the second limiting elastic piece are arranged at intervals in a first direction in sequence, and are all connected to the bottom plate. The first limiting elastic piece, the second limiting elastic piece, and the bottom plate enclose an insertion slot for inserting the card tray; the direction in which the card tray is inserted into the insertion slot intersects with the first direction. The first limiting portion is connected to the bottom plate and is arranged along the direction in which the card tray is inserted into the insertion slot with the first limiting elastic piece; the first limiting portion extends along the direction in which the card tray is inserted into the insertion slot and arches towards the first side plate. The first limiting portion, the bottom plate, and the first side plate enclose an installation space for installing a push rod.

[0007] The card holder provided by the embodiment of the present application forms an insertion slot for inserting a card tray by surrounding it with a bottom plate, a first limiting elastic piece, and a second limiting elastic piece, and forms an installation space for installing a push rod by surrounding it with the bottom plate, a first limiting portion, and a first side plate. The first limiting portion and the first limiting elastic piece are arranged along the direction in which the card tray is inserted into the insertion slot. When the push rod is installed in this installation space, there is no need to reserve a large space for the stamping and bending die for forming the first limiting portion and the first limiting elastic piece and the two bending rounded corners. Only the distance of the maximum deformation displacement of the first limiting elastic piece along the first direction during the insertion and removal of the card tray needs to be reserved, effectively reducing the width of the card holder along the first direction, and further reducing the overall width of the SIM card assembly, which can release more installation space for other components of the electronic device using this card holder, facilitating the optimization of the overall layout of the electronic device and improving the performance of the electronic device.

[0008] In addition, when the push rod slides along the direction in which the card tray 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 beneficial to improving the service life of both.

[0009] In some possible implementation manners of the first aspect, along the direction in which the card tray is inserted into the insertion slot, the first limiting portion is located behind the first limiting elastic piece. In this way, the inclination direction of the part of the first limiting portion close to the first limiting elastic piece relative to the first side plate can prevent the front end of the card tray from abutting against the first limiting portion and getting stuck during the insertion process, and the inclination direction of the part of the first limiting portion far from the first limiting elastic piece relative to the first side plate can prevent the front end of the push rod from abutting against the first limiting portion and getting stuck during the process of assembling the push rod to the card holder.

[0010] In some possible implementation manners of the first aspect, the first limiting portion and the first limiting elastic piece are of an integral structure. In this way, the design and processing difficulty of the first limiting portion and the first limiting elastic piece can be reduced.

[0011] In some possible implementation manners of the first aspect, the first limiting portion and the first limiting elastic piece are arranged at intervals. In this way, the setting position of the first limiting portion is more flexible, and the actual extension length of the first limiting portion can be smaller, and the space occupied by the first limiting portion is smaller.

[0012] In some possible implementation manners of the first aspect, the card holder further includes a first connecting plate. The first connecting plate extends from the edge of the first side plate away from the bottom plate towards the first limiting elastic piece, and the first connecting plate forms the wall plate of the aforementioned installation space. In this way, the first connecting plate can be used to limit the movement of the push rod relative to the card holder in the direction perpendicular to the bottom plate, ensuring the overall reliability of the SIM card assembly.

[0013] In some possible implementations of the first aspect, the end of the first limiting portion away from the first limiting elastic piece is located on the side of the first limiting elastic piece facing away from the second limiting elastic piece. In this way, it is possible to prevent the front end of the card holder from jamming against the first limiting portion and being unable to be inserted smoothly during the process of inserting the card holder into the card seat.

[0014] In some possible implementations of the first aspect, along the direction in which the card holder is inserted into the insertion slot, at least a part of the first connecting plate is aligned with at least a part of the first limiting portion. In this way, it is possible to limit the movement of the push rod in the first direction, the direction in which the card holder is inserted into the aforementioned insertion slot, and the direction perpendicular to the bottom plate at the same section of the push rod, which can prevent the push rod from shaking during the sliding process, and further scratching the limiting structure connected to it, resulting in a reduction in the service life of the card seat assembly. In addition, it is also convenient to remove the card holder from the card seat.

[0015] In a second aspect, an embodiment of the present application provides a card seat assembly, which includes a card seat, a card holder, and a push rod. The card seat is the card seat in any of the above implementations. The card holder is inserted into the aforementioned insertion slot. The push rod is installed in the aforementioned installation space and can slide relative to the card seat along the direction in which the card holder is inserted into the insertion slot.

[0016] Since the card seat assembly provided by the embodiment of the present application includes the card seat in any of the above implementations, the two can solve the same problems and achieve the same effects, which will not be elaborated here.

[0017] In some possible implementations of the second aspect, the card holder includes a first side surface and a second side surface. The first side surface faces the first limiting elastic piece, and the first side surface has a first clamping groove. The second side surface faces the second limiting elastic piece, and the second side surface has a second clamping groove. The first limiting elastic piece 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 are both connected to the bottom plate. The first bending section arches towards the direction close to the first side surface and is clamped in the first clamping groove. The second limiting elastic piece 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 are both connected to the bottom plate. The second bending section arches towards the direction close to the second side surface and is clamped in the second clamping groove.

[0018] In this way, the first limiting elastic piece and the second limiting elastic piece can both clamp and fix the card holder after the card holder is inserted into the seat body, and it is also convenient to remove the card holder from the card seat to replace and repair the SIM card.

[0019] In some possible implementations of the second aspect, the card tray further includes a first surface facing away from the bottom plate. The first surface has a first groove and a second groove arranged at intervals along the direction in which the card tray is inserted into the socket. The first groove has a first groove side wall facing away from the second groove, a second groove side wall facing away from the second limiting elastic piece, and a third groove side wall connected between the first groove side wall and the second groove side wall. From the first groove side wall to the second groove side wall, the third groove side wall extends in a direction gradually away from the second groove; the position where the third groove side wall meets the second groove side wall is the first position. The second groove has a fourth groove side wall facing away from the first groove and a fifth groove side wall facing away from the second limiting elastic piece, and the position where the fourth groove side wall meets the fifth groove side wall is the second position. Along the direction in which the card tray is inserted into the socket, the bottom wall of the second engaging groove is located between the first position and the second position.

[0020] In this way, when the card tray is disassembled, the acting force received by the front side groove side wall of the second engaging groove can be dispersed to the part of the card tray between the two SIM cards, and the part of the card tray between the front-side one of the first groove and the second groove and the second side surface, and the wall thickness of the part of the card tray between the groove side wall of the rear-side one of the first groove and the second groove and the groove wall of the second engaging groove can be as large as possible. Therefore, the card tray with this structural form has better strength, can reduce the wall thickness of the card tray while ensuring the use strength of the card tray, and further reduce the overall width of the SIM card assembly.

[0021] In some possible implementations of the second aspect, the card tray further includes a first surface facing away from the bottom plate. The first surface has a first groove and a second groove arranged at intervals along the direction in which the card tray is inserted into the socket. The first groove has a first groove side wall facing away from the second groove, a second groove side wall facing away from the first limiting elastic piece, and a third groove side wall connected between the first groove side wall and the second groove side wall. From the first groove side wall to the second groove side wall, the third groove side wall extends in a direction gradually away from the second groove; the position where the third groove side wall meets the second groove side wall is the first position. The second groove has a fourth groove side wall facing away from the first groove and a fifth groove side wall facing away from the first limiting elastic piece, and the position where the fourth groove side wall meets the fifth groove side wall is the second position. Along the direction in which the card tray is inserted into the socket, the bottom wall of the first engaging groove is located between the first position and the second position.

[0022] In this way, when the card tray is disassembled, the acting force received by the front side groove side wall of the first engaging groove can be dispersed to the part of the card tray between the two SIM cards, and the part of the card tray between the front-side one of the first groove and the second groove and the first side surface, and the wall thickness of the part of the card tray between the groove side wall of the rear-side one of the first groove and the second groove and the groove wall of the first engaging groove can be as large as possible. Therefore, the card tray with this structural form has better strength, can reduce the wall thickness of the card tray while ensuring the use strength of the card tray, and further reduce the overall width of the SIM card assembly.

[0023] In some possible implementations of the second aspect, the position where the side wall of the third groove meets the side wall of the first groove is the third position. Along the direction in which the card tray is inserted into the insertion slot, the second groove is located in front of the first groove, the bottom wall of the first card slot is located between the first position and the third position, and the bottom wall of the second card slot is located between the first position and the third position. In this way, the structure of the card tray portion corresponding to the SIM card cut corner can be fully utilized to ensure the strength of the card tray so as to facilitate its narrowing design, and the wall thickness of the card tray portion at the first card slot and the second card slot can be prevented from being too small to reduce the strength of the card tray.

[0024] In some possible implementations of the second aspect, the card holder includes a plastic structure and a metal frame, the metal frame is embedded in the plastic structure, the minimum wall thickness of the metal frame along the direction perpendicular to the second direction is the first thickness, the thickness of the metal frame along the second direction is the second thickness, and the first thickness is greater than or equal to 0.8 times the second thickness; wherein the second direction is perpendicular to 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 parts during insertion or removal. In addition, when the thickness of the metal frame is thin, the yield rate of cutting the blank plate to form the metal frame can be guaranteed, thereby ensuring the reliability of the card holder.

[0025] 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 tray is inserted into the plug-in slot, the stopper is located on the rear side of the first side plate. 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 tray; along the first direction, the distance between the first end and the card tray is greater than or equal to the distance between the push rod and the card tray, and the distance between the second end and the card tray is less than the distance between the push rod and the card tray. 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 tray is inserted into the plug-in slot.

[0026] In this way, the cross-sectional area of ​​the stopper can be larger than the cross-sectional area of ​​the push rod, so that the ejector pin and the push rod can cooperate with each other to remove the card tray. In addition, when the push rod pushes the card tray to move in the disassembly direction to the card ejection state through the toggle member, the second limit portion can contact with the fifth connecting section or have a matching gap 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.

[0027] In a third aspect, an embodiment of the present application provides an electronic device, the 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, the card holder is disposed in the housing, and the card holder is inserted into the card holder through the card insertion hole.

[0028] Since the electronic device provided by the embodiment of the present application includes the card seat assembly in any of the above implementation manners, the two can solve the same problems and achieve the same effects, which will not be elaborated here.

Specifically, the electronic device includes but is not limited to mobile phones, tablet computers, smart watches, wireless landline phones, smart glasses, and smart home intercom systems, etc.

[0063] Please also read Figure 1 and Figure 2 , Figure 1 A perspective view of an electronic device 100 provided in some embodiments of the present application, Figure 2 for Figure 1 The electronic device 100 is a schematic diagram of an exploded structure of the electronic device 100. This embodiment is exemplified by taking the electronic device 100 as a folding screen mobile phone. The electronic device 100 includes a housing 10, a SIM card assembly 20 and a folding screen 30.

[0064] Understandably, Figure 1 and Figure 2 The electronic device 100 includes some components, the shapes and sizes of which are not limited to Figure 1 and Figure 2 Moreover, in addition to these components, the electronic device 100 also includes internal electronic components such as a battery, a camera, a speaker, a vibration motor, etc. When the electronic device 100 is another product, the electronic device 100 may not include the folding screen 30.

[0065] The housing 10 is used to protect the folding screen 30 and internal electronic components. Figure 1 and Figure 2 In the illustrated embodiment, 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 the present application.

[0066] The first housing 11 and the second housing 12 are used to support the folding screen 30. For details, please continue to refer to Figure 1 and Figure 2 The folding screen 30 includes a first folding screen part 31 and a second folding screen part 32 . The first shell 11 supports the first folding screen part 31 , and the second shell 12 supports the second folding screen part 32 .

[0067] See also Figure 3 , Figure 3 for Figure 1 A schematic diagram of the cross-sectional structure of the electronic device 100 shown 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 at 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 portion 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.

[0068] Similarly, please continue to read Figure 3 The second housing 12 includes a second front housing 121 and a second back cover 122. The second front housing 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 housing 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 housing 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.

[0069] Please also read Figure 2 and Figure 3 The housing 10 further includes a rotating shaft mechanism 13, and the first housing 11 and the second housing 12 are rotatably connected by means of the rotating shaft mechanism 13, so that the folding screen 30 can be Figures 1 - 3 The expanded state shown collapses to the collapsed state.

[0070] 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 a 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 a 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 easier 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 an unfolded state and working, the user can view the image or video displayed on the folding screen 30 from the display side.

[0071] When the folding screen 30 is in the unfolded state, the thickness of the folding screen mobile phone is the first thickness h; when the folding screen 30 is in the folded state, the thickness of the folding screen mobile phone is the second thickness H; the second thickness H is approximately twice the first thickness h. Based on this, in order to improve the portability and hand feel, folding screen mobile phones are increasingly pursuing thinness 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 more and more to ensure the performance of the entire electronic device 100.

[0072] See also Figure 4 , Figure 4 for Figure 3 In the partial enlarged view of point B in the middle, a card insertion hole 10 a is provided on the housing 10 , and the card insertion hole 10 a runs through both the inner and outer sides of the housing 10 . Figure 3 andFigure 4 In the illustrated embodiment, the card slot 10a is provided in the first frame segment K. The first frame segment K is located on the first frame 1112, and the first frame segment K forms the end of the first housing 11 away from the rotating shaft mechanism 13. The length direction of the first frame segment K is parallel to the rotation axis of the rotating shaft mechanism 13. The card slot 10a communicates the external space of the first housing 11 with the first accommodation cavity C1. In some other embodiments, the length direction of the first frame segment K may also be perpendicular to the rotation axis of the rotating shaft mechanism 13. In still some other embodiments, the card slot 10a may also be provided at 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 will not be specifically limited herein.

[0073] The SIM card assembly 20 is disposed at the card slot 10a. Please also refer to Figures 4 - 6 , Figure 5 is Figure 4 a schematic structural view of the SIM card assembly 20 of the illustrated electronic device 100, Figure 6 and Figure 5 is a schematic structural view of the SIM card assembly 20 seen from another direction. The SIM card assembly 20 includes a card seat assembly 21 and a SIM card 22. The card seat assembly 21 includes a card seat 211, a card tray 212, and a card ejection device 213.

[0074] The card seat 211 is disposed in the housing 10. Optionally, please continue to refer to Figure 4 , the card seat 211 is disposed in the aforementioned first accommodation cavity C1. Specifically, the card seat 211 may be fixed on the circuit board 40 in the first accommodation cavity C1 and electrically connected to the circuit board 40 through the card seat terminals 2112. The SIM card 22 is disposed on the card tray 212. The card tray 212 is inserted into the card seat 211 through the card slot 10a so that the SIM card terminals 221 on the SIM card 22 are in contact and electrically connected to the card seat terminals 2112, and then electrically connected to the circuit board 40 to access the user identity information, and form a complete middle frame appearance with the first frame segment K.

[0075] 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 inserting into the insertion slot. The direction in which the card tray 212 is inserted into the insertion slot refers to the moving direction of the card tray 212 during the process of being inserted into the insertion slot of the card holder 211 via the card insertion hole 10a. The direction in which the card tray 212 is inserted into the insertion slot is restricted by the card insertion hole 10a and the space in the card holder 211 for accommodating the card tray 212. Based on this, for the convenience of describing the following embodiments, the direction in which the card tray 212 is inserted into the insertion slot is defined as the +X axis direction, and the direction of the card tray 212 (the direction opposite to the direction of inserting into the insertion slot) is 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, and the first direction is the Y axis direction, that is, the first direction intersects with 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, and 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 in pairs. Of course, the insertion direction of the card tray 212 can also be positioned as other axis directions, which is not specifically limited herein. 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.

[0076] Please continue to refer to Figure 5 and Figure 6 , the card holder 211 includes a base body 2111 and card holder terminals ( Figure 5 and Figure 6 not shown in the figure), and the card holder terminals are relatively fixed to the base body 2111. The base body 2111 includes a bottom plate 21111, a first side plate 21112, a second side plate 21113, a first limiting elastic piece 21114, a second limiting elastic piece 21115, and a second limiting portion 21116. The bottom plate 21111 has a third surface 21111a, and the first side plate 21112, the second side plate 21113, the first limiting elastic piece 21114, the second limiting elastic piece 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 elastic piece 21114, the second limiting elastic piece 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 elastic piece 21114, and the second limiting elastic piece 21115 are arranged at intervals in the Y axis direction and are all connected to the bottom plate 21111. The first limiting elastic piece 21114, the second limiting elastic piece 21115, and the bottom plate 21111 enclose an insertion slot for inserting the card tray 212.

[0077] Both opposite ends of the first limiting elastic piece 21114 are connected to the bottom plate 21111, and a part of the first limiting elastic piece 21114 arches and bends towards the direction close to the second limiting elastic piece 21115.

[0078] The second side plate 21113 may include sub-side plates arranged at intervals in the X-axis direction. The second limiting elastic piece 21115 is located between the two aforementioned sub-side plates. Both opposite ends of the second limiting elastic piece 21115 are connected to the bottom plate 21111, and a part of the second limiting elastic piece 21115 arches and bends towards the direction close to the first limiting elastic piece 21114. In some examples, the two ends of the second limiting elastic piece 21115 in the X-axis direction may be coplanar with the second side plate 21113 to reduce the width of the overall seat body 2111 in the Y-axis direction. In some other embodiments, the seat body 2111 may not include the second side plate 21113 either.

[0079] The second limiting portion 21116 is connected to the bottom plate 21111. The second limiting portion 21116 is located between the first limiting elastic piece 21114 and the first side plate 21112. The second limiting portion 21116 is spaced from both the first side plate 21112 and the first limiting elastic piece 21114. The second limiting portion 21116, the bottom plate 21111, and the first side plate 21112 enclose an installation space for accommodating and fitting the push rod 2131 described below. Figure 5 and Figure 6 In the illustrated embodiment, the number of the second limiting portions 21116 is two, and the two second limiting portions 21116 are arranged at intervals in the X-axis direction to have a relatively reliable limiting and guiding effect on the push rod 2131. In some other embodiments, the number of the second limiting portions 21116 may also be three or more other numbers, and multiple second limiting portions 21116 are arranged at intervals in the X-axis direction.

[0080] Please continue to refer to Figure 5 and Figure 6 , the card tray 212 is detachably inserted into the seat body 2111, and is inserted into the aforementioned insertion slot, and is clamped and fixed by the first limiting elastic piece 21114 and the second limiting elastic piece 21115. Specifically, the card tray 212 includes a first side surface 212a and a second side surface 212b. The first side surface 212a faces the first limiting elastic piece 21114, and a first clamping groove 212a1 is provided on the first side surface 212a. The second side surface 212b faces the second limiting elastic piece 21115, and a second clamping groove 212b1 is provided on the second side surface 212b. The bent portion of the first limiting elastic piece 21114 is clamped in the first clamping groove 212a1, and the bent portion of the second limiting elastic piece 21115 is clamped in the second clamping groove 212b1.

[0081] On this basis, a groove is provided on the card tray 212, and the groove forms a position for installing the SIM card 22. Figure 5 and Figure 6In the illustrated embodiment, the card tray 212 has two card positions. Specifically, the card tray 212 also has a first surface 212c and a second surface 212d arranged at intervals along the Z-axis direction, and the first surface 212c is opposite to the third surface 21111a. The first surface 212c has a first groove 212c1 and a second groove 212c2 arranged at intervals along the X-axis direction. Based on this, the number of SIM cards 22 is two, and the two SIM cards 22 are respectively accommodated in the first groove 212c1 and the second groove 212c2. In this way, the electronic device 100 can meet the dual-card requirements, so that the user can use two mobile phone numbers for communication on one mobile phone at the same time. In some other embodiments, the number of grooves on the SIM card 22 and the card tray 212 can also be one, three or more than three.

[0082] On the basis of the above, please continue to refer to Figure 5 and Figure 6 The card ejection device 213 includes a push rod 2131 and a toggle member 2132. The push rod 2131 is installed and matched in the aforementioned installation space, that is, the push rod 2131 is accommodated and matched between the second limit portion 21116 and the first side plate 21112, and the push rod 2131 can slide relative to the card holder 211 along the X-axis direction. On this basis, the toggle member 2132 is located at the front side of the card holder 212 and can rotate relative to the card holder 211 around 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 plug-in slot (+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.

[0083] Please continue reading Figure 5 In conjunction with Figure 1 , a pin hole 10b is also provided on the first frame segment K. Along the insertion direction (+X axis direction) of the card tray 212, the pin hole 10b is located at the rear side of the push rod 2131 and is coaxially arranged with the push rod 2131. During the card ejection process, the push rod 2131 can be driven to move forward along the direction (+X axis direction) in which the card tray 212 is inserted into the insertion slot by means of the pin hole 10b, so as to push the push rod 2131 to push the second swing arm portion 21322, so that the second swing arm portion 21322 rotates along the direction a1 around the first axis L1, and the first swing arm portion 21321 rotates along the direction a2, thereby pushing the card tray 212 out along the disassembly direction (-X axis direction) of the card tray 212, so as to facilitate the replacement and repair of the SIM card 22.

[0084] Conversely to the above process, during the card insertion process, when the card tray 212 is inserted into the card socket 211 through the card insertion hole 10a along the direction in which it is inserted into the insertion slot (+X axis direction), it can push the first swing arm portion 21321 to rotate along the direction a3, so that the second swing arm portion 21322 rotates along the direction a4, so as to push the push rod 2131 to move a certain distance along the removal direction of the card tray 212 (-X axis direction), thereby realizing the reset of the push rod 2131 to facilitate the next card ejection operation.

[0085] Please refer to Figure 5 and Figure 7 , Figure 7 as Figure 5 a partial structural schematic diagram of the SIM card assembly 20 when viewed from the Z-axis direction. Figure 5 and Figure 7 In the embodiment shown, the portion of the first limiting elastic piece 21114 connected to the bottom plate 21111 and the second limiting portion 21116 are arranged opposite to each other in the Y-axis direction. Therefore, the overall width of the card socket assembly 21 in the Y-axis direction is jointly defined by the width of the card tray 212, the plate thickness of the first side plate 21112, the plate thickness of the second limiting portion 21116, the thickness of the first limiting elastic piece 21114, the thickness of the second limiting elastic piece 21115, the thickness of the push rod 2131, the fitting clearance between the card tray 212 and the first limiting elastic piece 21114, the fitting clearance between the card tray 212 and the second limiting elastic piece 21115, and the distance between the first limiting elastic piece 21114 and the second limiting portion 21116. When ensuring the strength of each structural member, the plate thickness of the first side plate 21112, the thickness of the second limiting elastic piece 21115, the plate thickness of the second limiting portion 21116, the thickness of the first limiting elastic piece 21114, and the thickness of the push rod 2131 cannot be further thinned.

[0086] In some examples, the card holder 211 can be a metal structural member 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 elastic piece 21114 and the second limiting portion 21116 can be formed by stamping and bending processes. Therefore, the distance between the first limiting elastic piece 21114 and the second limiting portion 21116 needs to be greater than or equal to the maximum deformation displacement of the first limiting elastic piece 21114 during the card insertion and card ejection processes, and sufficient avoidance space also needs to be reserved for the stamping and bending die to achieve stamping and bending with 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 relatively large overall width of the SIM card assembly 20, restricting the sizes of other components inside the electronic device 100. For example, it restricts the size of the battery and affects the battery life of the entire electronic device 100. Another example is that it restricts the size of the speaker module and affects the low-frequency performance and loudness of the speaker module, etc.

[0087] Please refer to Figure 5 and Figure 8 , Figure 8 is Figure 5 a schematic structural view of the card tray 212 of the SIM card assembly 20 when viewed from the Z-axis direction. The first clamping groove 212a1 includes a ninth groove side wall 212a11, a first groove bottom wall 212a12, and a sixth groove side wall 212a13 that are sequentially connected along the direction in which the card tray 212 is inserted into the insertion slot (+X-axis direction). The sixth groove side wall 212a13 is located in front of the ninth groove side wall 212a11; the second clamping groove 212b1 has a seventh groove side wall 212b11, a second groove bottom wall 212b12, and an eighth groove side wall 212b13. The eighth groove side wall 212b13 is located in front of the seventh groove side wall 212b11.

[0088] Figure 5 and Figure 8 In the embodiments shown, when the number of SIM cards 22 is two, along the direction in which the card tray 212 is inserted into the insertion slot (+X-axis direction), both the sixth groove side wall 212a13 and the eighth groove side wall 212b13 are located in front of the groove side wall of the second groove 212c2 that faces away from the first groove 212c1. Since the sixth groove side wall 212a13 and the eighth groove side wall 212b13 are the main force-bearing surfaces during the card ejection process, at least the wall thickness of the card tray part in front of the first clamping groove 212a1 and the wall thickness of the card tray part in front of the second clamping groove 212b1 in the Y-axis direction need to be as large as possible to ensure the strength of the card tray 212. Therefore, the width of the card tray 212 is relatively large, which in turn leads to a relatively large overall width of the SIM card assembly 20.

[0089] To solve the above problems, please refer to Figure 9 , Figure 9 which is a schematic structural diagram of the SIM card component 20 provided by some other embodiments of the present application when viewed from the Z-axis direction. Figure 9 In the illustrated embodiment, the second limiting portion 21116 opposite to the connection between the first limiting elastic piece 21114 and the bottom plate 21111 is removed. Although the second limiting portion 21116 on the front side of the first limiting elastic piece 21114 can also limit the push rod 2131, the push rod 2131 will shake during the sliding process, which is not convenient for disassembling the card tray 212 to repair and replace the SIM card 22.

[0090] Please also refer to Figures 10 - 12 , Figure 10 which is Figure 4 another schematic structural diagram of the SIM card component 20 of the electronic device 100 shown, Figure 11 and is Figure 10 a schematic structural diagram of the SIM card component 20 when viewed from another direction, Figure 12 and is Figure 11 a schematic exploded view of the SIM card component 20 shown. The SIM card component 20 includes a card seat assembly 21 and a SIM card 22. The card seat assembly 21 includes a card seat 211, a card tray 212, and a card ejection device 213.

[0091] Please refer to Figure 10 , Figure 12 and Figure 13 , Figure 13 which is Figure 10 a partial schematic structural diagram of the SIM card component 20 when viewed from the Z-axis direction. Figure 12 and Figure 13 In the illustrated embodiment, the card seat 211 includes a seat body 2111 and card seat terminals 2112. The structure of the card seat 211 is similar to that of the card seat 211 in the embodiment shown in Figure 5 , except that: the card seat terminals 2112 include an insulating bracket 21121 and conductive terminals 21122 fixed on the insulating bracket 21121. The insulating bracket 21121 can be fixed on the seat body 2111 or on the circuit board 40. The conductive terminals 21122 can be elastic terminals and are fixed on the circuit board 40 by welding to achieve electrical connection with the circuit board 40.

[0092] The first limiting elastic piece 21114 includes a first connecting section 21114a, a first bending section 21114b, and a second connecting section 21114c that 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 bending section 21114b arches towards the first side surface 212a and is clamped in the first clamping groove 212a1. The second limiting elastic piece 21115 includes a third connecting section 21115a, a second bending section 21115b, and a fourth connecting section 21115c that 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 bending section 21115b arches towards the second side surface 212b and is clamped in the second clamping groove 212b1.

[0093] In some examples, the first limiting elastic piece 21114 and the second limiting elastic piece 21115 are sheet-shaped. The first limiting elastic piece 21114 and the second limiting elastic piece 21115 can be an integral structure with the bottom plate 21111 and are formed by a stamping and bending process. In other examples, the first limiting elastic piece 21114 and the second limiting elastic piece 21115 can also be fixed to the bottom plate 21111 by welding or clamping.

[0094] In this way, the first limiting elastic piece 21114 and the second limiting elastic piece 21115 can both clamp and fix the card holder 212 after the card holder 212 is inserted into the seat body 2111, and it is also convenient to disassemble the card holder 212 from the card seat 211 to replace and repair the SIM card 22.

[0095] Please refer to Figures 12 - 14 , Figure 14 is Figure 13 a partial enlarged view of the C position in. The card seat 211 further includes a first limiting portion 21117. The first limiting portion 21117 is connected to the bottom plate 21111 and is arranged along the X-axis direction with the first limiting elastic piece 21114. Figures 12 - 14 In the illustrated embodiment, the first limiting portion 21117 is located at the rear side of the first limiting elastic piece 21114. The first limiting portion 21117 extends along the X-axis direction and arches towards the first side plate 21112.

[0096] Specifically, the first limiting portion 21117 includes a connected first extension segment 21117a and a second extension segment 21117b. Along the insertion direction of the card holder 212 (+X axis direction), the second extension segment 21117b is located at the rear side of the first extension segment 21117a, that is, the first extension segment 21117a gradually approaches the first side plate 21112 from near the first limiting elastic piece 21114 to far from the first limiting elastic piece 21114, and the second extension segment 21117b gradually approaches the first side plate 21112 from one end far from the first limiting elastic piece 21114 to one end near the first limiting elastic piece 21114. Based on this, the first limiting portion 21117, the bottom plate 21111 and the first side plate 21112 enclose an installation space, and the push rod 2131 is installed and fitted in this installation space, that is, this installation space is used to install the push rod 2131.

[0097] In some examples, the first limiting portion 21117 as a whole can be in the shape of a sheet perpendicular to the bottom plate 21111, and the front end of the first extension segment 21117a of the first limiting portion 21117 can be connected to the bottom plate 21111. Specifically, the first limiting portion 21117 and the bottom plate 21111 can be of an integral structure and formed 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.

[0098] In this way, by arranging the first limiting portion 21117 and the first limiting elastic piece 21114 along the X-axis direction, there is no need to reserve a large space for the stamping and bending die and the two bending round corners between the push rod 2131 and the first limiting elastic piece 21114. Only the distance of the maximum deformation displacement of the first limiting elastic piece 21114 during the insertion and removal of the card holder 212 needs to be reserved, effectively reducing the width of the card holder 211 along the Y-axis direction, and further reducing the overall width of the SIM card assembly 20, which can release more installation space for other components of the electronic device 100, is beneficial to optimizing the layout of the whole machine of the electronic device 100, and further improving the performance of the electronic device 100.

[0099] 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.

[0100] In addition, when the first limiting portion 21117 is located at the rear side of the first limiting elastic piece 21114, the inclination direction of the first extension section 21117a of the first limiting portion 21117 relative to the first side plate 21112 can prevent the front end of the card holder 212 from abutting against the first limiting portion 21117 and getting stuck during the insertion process, so that the insertion cannot be carried out smoothly. The inclination direction of the second extension section 21117b of the first limiting portion 21117 relative to the first side plate 21112 can prevent the front end of the push rod 2131 from abutting against the first limiting portion 21117 and getting stuck during the process of assembling the push rod 2131 onto the card holder 211, so that the assembly cannot be carried out smoothly.

[0101] Based on the above, please continue to refer to Figure 12 and Figure 14 , the first limiting portion 21117 and the first limiting elastic piece 21114 are of 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 elastic piece 21114. In some examples, the first limiting portion 21117, the bottom plate 21111 and the first limiting elastic piece 21114 can be of an integral structure. By first cutting a notch on the blank plate of the bottom plate 21111 to form a cantilever and then adopting a stamping and bending process to form the first limiting portion 21117 and the first limiting elastic piece 21114. In this way, the design and processing difficulty of the first limiting portion 21117 and the first limiting elastic piece 21114 can be reduced.

[0102] In some other embodiments, please refer to Figure 15 , Figure 15 is a schematic structural view of the SIM card assembly 20 provided by some other embodiments of the present application when viewed from the Z-axis direction. The first limiting portion 21117 can also be arranged at an interval from the first limiting elastic piece 21114. In this way, the setting position of the first limiting portion 21117 is more flexible, and moreover, the extension lengths of the first extension section 21117a and the second extension section 21117b can be smaller, and the space occupied by the first limiting portion 21117 is smaller. In some other embodiments, please continue to refer to Figure 15 , the first limiting portion 21117 can also be located at the front side of the first limiting elastic piece 21114, and the first limiting portion 21117 can also be located at a position opposite to the bent portion of the first limiting elastic piece 21114, which can also reduce the width of the SIM card assembly 20.

[0103] Based on the above, please return to refer to Figure 14, one end of the second extension section 21117b away from the first extension section 21117a is located on the side of the first limiting elastic piece 21114 facing away from the second limiting elastic piece 21115, that is, one end of the first limiting portion 21117 away from the first limiting elastic piece 21114 is located on the side of the first limiting elastic piece 21114 facing away from the second limiting elastic piece 21115. In this way, during the process of inserting the card holder 212 into the card seat 211, it can be prevented that the front end of the card holder abuts against the second extension section 21117b and gets stuck, making it impossible to insert smoothly.

[0104] Please refer to Figure 10 and Figure 14 , the seat body 2111 further includes a first connecting plate 21118. The first connecting plate 21118 extends from the edge of the first side plate 21112 away from the bottom plate 21111 towards the direction close to the first limiting elastic piece 21114. The first connecting plate 21118 forms a wall plate of the installation space for installing the push rod 2131. The first connecting plate 21118 can be used for welding and fixing with the circuit board 40, and can also be used to limit the movement of the push rod 2131 along the Z-axis direction. In this way, the first connecting plate 21118 can multiplex two different functions, and can reduce the design and manufacturing difficulty of the card seat 211. Figure 10 and Figure 14 In the embodiment shown, the number of the first connecting plates 21118 is multiple, which can ensure the reliability of fixing with the circuit board 40 and can also ensure the reliability of limiting the push rod 2131. On this basis, connecting plates for welding with the circuit board 40 can also be provided on the remaining structures (such as the second side plate 21113, etc.) of the seat body 2111.

[0105] On the above basis, please continue to refer to Figure 14 , along the X-axis direction, at least part of the first connecting plate 21118 is aligned with at least part of the first limiting portion 21117. In this way, the movement of the push rod 2131 along the X-axis direction, Y-axis direction, and Z-axis direction can be limited at the same section of the push rod 2131, and it can be prevented that the push rod 2131 shakes during the sliding process, thereby scratching the limiting structure connected with it, resulting in a reduction in the service life of the card seat assembly 211. In addition, it is also convenient to remove the card holder 212 from the card seat 211.

[0106] On the above basis, please refer to Figure 13 , Figure 16 and Figure 17 , Figure 16 is Figure 13 the schematic structural diagram of the SIM card assembly 20 in the card ejection state shown in Figure 17 is Figure 16Partial enlarged view at position D in the figure. The card ejection device 213 further includes a stop portion 2133 and a fifth connection section 2134. Along the direction in which the card holder 212 is inserted into the insertion slot, the stop portion 2133 is located at the rear side of the first side plate 21112. The stop portion 2133 includes a first end 21331 and a second end 21332 arranged along the Y-axis direction. Along the Y-axis direction, the first end 21331 is located on the side of the first side plate 21112 facing away from the first limiting elastic piece 21114, and the second end 21332 is located on the side of the push rod 2131 facing away from the first side plate 21112. That is, the second end 21332 is located between the first end 21331 and the card holder 212. The distance between the first end 21331 and the card holder 212 is greater than or equal to the distance between the push rod 2131 and the card holder 212, and the distance between the second end 21332 and the card holder 212 is less than the distance between the push rod 2131 and the card holder 212. Based on this, the fifth connection section 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 is convenient for the top pin to abut and cooperate with the push rod 2131.

[0107] On this basis, the second extension section 21117b of the first limiting portion 21117 is parallel to the fifth connection section 2134, or the second extension section 21117b gradually moves away from the fifth connection section 2134 from the end close to the first side plate 21112 to the end far from the first side plate 21112. When the stop portion 2133 contacts the first side plate 21112, there is a fitting gap between the fifth connection section 2134 and the second extension section 21117b. The fitting gap is greater than or equal to 0 and less than or equal to 0.2 mm. In this way, when the push rod 2131 slides along the direction in which the card holder 212 is inserted into the insertion slot (+X-axis direction) under the action of the top pin, the push rod 2131 pushes the card holder 212 to move outside the electronic device 100 through the toggling member 2132 to the card ejection state as shown in Figure 16 the figure. At this time, the second side plate 21112 can jointly limit the push rod 2131 from continuing to slide along the direction in which the card holder 212 is inserted into the insertion slot (+X-axis direction) with the second extension section 21117b, ensuring the reliability of the card seat assembly 21.

[0108] In some other embodiments, when the push rod 2131 slides along the direction in which the card holder 212 is inserted into the insertion slot (+X-axis direction) under the action of the top pin, the push rod 2131 pushes the card holder 212 to move outside the electronic device 100 through the toggling member 2132 to the card ejection state as shown in Figure 16When in the card ejection state shown, the stopper portion 2133 may not contact the first side plate 21112 either. The second extension segment 21117b abuts against the fifth connection segment 2134 to limit the further sliding of the push rod 2131 in the direction in which the card tray 212 is inserted into the insertion slot (+X-axis direction). That is, the fifth connection segment 2134 can cooperate with the first limiting portion 21117 to limit the movement of the push rod 2131 in the direction in which the card tray 212 is inserted into the insertion slot.

[0109] On the basis of the above, please refer to Figure 18 and Figure 19 , Figure 18 which is Figure 10 a schematic structural diagram of the card tray 212 of the SIM card assembly 20 shown, Figure 19 and Figure 18 a schematic exploded structural diagram of the card tray 212 shown. The card tray 212 includes a metal skeleton 2121 and a plastic structure 2122. The metal skeleton 2121 is embedded in the plastic structure 2122, and the shape of the metal skeleton 2121 is adapted to the overall shape of the card tray 212. In this way, the card tray 212 has good toughness and high strength, and will not scratch the housing 10 of the electronic device 100 and other structural components during the process of insertion or removal. Therefore, the card tray 212 has good reliability and high service life. In some other embodiments, the card tray 212 may also be a plastic structural member. In still some other embodiments, the card tray 212 may also be a metal structural member.

[0110] Specifically, the metal skeleton 2121 includes a first rib plate 21211 and a second rib plate 21212 extending in the Y-axis direction, and a third rib plate 21213 and a fourth rib plate 21214 extending in the X-axis direction. The first rib plate 21211 is located between the first groove 212c1 and the second groove 212c2, and the second rib plate 21212 is located on the side of the second groove 212c2 away from the first groove 212c1. The third rib plate 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 plate 21211 and the second rib plate 21212; the fourth rib plate 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 plate 21211 and the other end of the second rib plate 21212. The ends of the third rib plate 21213 and the fourth rib plate 21214 away from the second rib plate 21212 extend to the side of the first groove 212c1 facing away from the second groove 212c2.

[0111] Please continue to refer to Figure 18, the width of the card tray 212 in the Y-axis direction is jointly defined by the width of the SIM card 22, the wall thickness of the plastic structure 2122 between the metal skeleton 2121 and the first limiting elastic piece 21114, the wall thickness of the plastic structure 2122 between the metal skeleton 2121 and the SIM card 22, and the fitting gap between the SIM card 22 and the card tray 212. Since directly reducing the wall thickness of the metal skeleton 2121 on the basis of the card tray 212 in the Figure 8 shown embodiment will cause the strength of the card tray 212 to decrease, and further reduce the overall reliability of the SIM card assembly 20.

[0112] Based on this, please continue to refer to Figure 18 , Figure 18 In the shown embodiment, along the direction in which the card tray 212 is inserted into the insertion slot, the second groove 212c2 is located on the front side of the first groove 212c1. The second groove 212c2 has a fourth groove side wall 212c21 extending in the Y-axis direction and a fifth groove side wall 212c22 extending in the X-axis direction. The fourth groove side wall 212c21 faces away from the first groove 212c1, and the fifth groove side wall 212c22 faces away from the second side surface 212b. The position where the fourth groove side wall 212c21 and the fifth groove side wall 212c22 meet is the second position N. The first groove 212c1 has a first groove side wall 212c11 extending in the Y-axis direction, a second groove side wall 212c12 extending in the X-axis direction, and a third groove side wall 212c13 connecting between the first groove side wall 212c11 and the second groove side wall 212c12. From the first groove side wall 212c11 to the second groove side wall 212c12, the third groove side wall 212c13 extends in a direction gradually away from the second groove 212c2. The first groove side wall 212c11 and the third groove side wall 212c13 face away from the second groove 212c2, and the second groove side wall 212c12 faces away from the second side surface 212b. The position where the third groove side wall 212c13 and the second groove side wall 212c12 meet is the first position M.

[0113] On this basis, along the direction in which the card tray 212 is inserted into the insertion slot, the second groove bottom wall 212b12 and the first groove bottom wall 212a12 are located between the first position M and the second position N, that is, the bottom wall of the second card slot 212b1 and the bottom wall of the first card slot 212a1 are located between the first position M and the second position N. In this way, when disassembling the card tray 212, the acting forces on the eighth groove side wall 212b13 and the sixth groove side wall 212a12 can be dispersed to act on the part of the card tray between the two SIM cards 22 and the part of the card tray between the second groove 212c2 and the first side surface 212a and the second side surface 212b. Therefore, the card tray 212 with this structural form has better strength, can reduce the wall thickness of the card tray 212 while ensuring the use strength of the card tray 212, and further reduce the overall width of the SIM card assembly 20.

[0114] On the above basis, along the direction in which the card holder 212 is inserted into the insertion slot, the position where the first slot side wall 212c11 and the third slot side wall 212c13 are joined is the third position P. 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 walls of the second engaging slot 212b1 and the first engaging slot 212a1 are located between the first position M and the third position P. In this way, it is possible to make full use of the structure of the part of the card holder corresponding to the cut corner of the SIM card 22, ensure the strength of the card holder 212 so as to facilitate its narrowing design, and prevent the wall thickness of the metal skeleton 2121 at the first engaging slot 212a1 and the second engaging slot 212b1 from being too small and reducing the strength of the card holder 212. It should be noted that the bottom wall of the second engaging slot 212b1 refers to the area in the second engaging slot 212b where the distance from the second side surface 212b is the largest, and the bottom wall of the first engaging slot 212a1 refers to the area in the first engaging slot 212a where the distance from the first side surface 212a is the largest; Figure 18 In the illustrated embodiment, the bottom walls of the second engaging slot 212b1 and the first engaging slot 212a1 are both flat surfaces. In some other embodiments, the bottom walls of the second engaging slot 212b1 and the first engaging slot 212a1 may also be straight lines or curves, and the present application does not limit this.

[0115] In some other embodiments, the second slot side wall 212c12 may also face away from the first side surface 212a, and the fifth slot side wall 212c22 faces away from the first side surface 212a. In some other embodiments, along the direction in which the card holder 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 side wall 212c12 faces away from the first side surface 212a and the fifth slot side wall 212c22 faces away from the first side surface 212a, it is only necessary to make the bottom wall of the first engaging slot 212a1 located between the first position M and the second position N, and there is no limitation on the second engaging slot 212b1; when the second slot side wall 212c12 faces away from the second side surface 212b and the fifth slot side wall 212c22 faces away from the second side surface 212b, it is only necessary to make the bottom wall of the second engaging slot 212b1 located between the first position M and the second position N, and there is no limitation on the first engaging slot 212a1.

[0116] On the basis above, the minimum wall thickness of the metal framework 2121 in the direction perpendicular to the Z-axis is the first thickness, and the wall thickness in the Z-axis direction is the second thickness, and the first thickness is greater than or equal to 0.8 times the second thickness of the metal framework 2121. Taking the thickness of the metal framework 2121 in the Z-axis direction as 0.4 mm as an example, the minimum wall thickness of the metal framework 2121 in 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, 0.48 mm, etc. In this way, when the thickness of the metal framework 2121 is relatively thin, the yield rate of cutting the blank plate to form the metal framework 2121 can be guaranteed, and thus the reliability of the card holder 212 can be guaranteed.

[0117] Taking the material thickness of the base body 2111 as 0.15 mm and the thickness of the metal framework 2121 of the card holder 212 in the Z-axis direction as 0.4 mm as an example, through the structural design of the aforementioned first limiting portion 21117, the width of the card seat 211 can be reduced by about 0.5 mm. Through the position design of the aforementioned first clamping groove 212a1 and the second clamping groove 212b1, the width of the card holder 212 can be reduced by about 0.3 mm. Therefore, Figure 10 the cumulative width of the card seat assembly 21 of the SIM card assembly 20 shown can be reduced by about 0.8 mm.

[0118] Please refer to Figure 20a 、 Figure 20b and Figure 21 , Figure 20a For Figure 8 is a schematic diagram of the applied torsional moment during the strength test of the card holder 212 shown, Figure 20b For Figure 18 is a schematic diagram of the applied torsional moment during the strength test of the card holder 212 shown. Figure 21 For Figure 20a and Figure 20b is a relationship curve graph of the torsional angle generated by the card holder 212 in Figure 20a and the required torsional moment. Among them, S1 is the test curve graph of the card holder 212 in Figure 20b , and S2 is the relationship curve graph of the card holder 212 in Figure 21 . It can be known from Figure 16 that through the position design of the first clamping groove 212a1 and the second clamping groove 212b1, when the width of the card holder 212 is reduced, Figure 8 the strength of the card holder 212 shown is still greater than

[0119] the strength of the card holder 212 described. Therefore, while ensuring the reliability of the card seat assembly 21, it is beneficial to improve the performance of the entire electronic device 100.It should be noted that the above embodiments introduce the application scenarios of the SIM card component 20 in a folding screen mobile phone. Of course, the SIM card component 20 provided by the embodiments of the present application can also be applied to other electronic device scenarios, such as phablets, smart watches, etc.
