[0012] In order to make the purpose, technical solution and advantages of the present application clearer, the following clearly and completely describes the technical solution of the present application in conjunction with specific embodiments and corresponding drawings of the present application. Obviously, the described embodiments are only some embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort are all within the scope of protection of the present application.

[0013] The technical solutions disclosed in the embodiments of the present application will be described in detail below in conjunction with the drawings.

[0014] 1 to 20, an embodiment of the present application discloses a card tray / card holder device for use in an electronic device.

[0015] The card tray-card holder apparatus disclosed in the embodiment of the present application includes a card retaining cover 100 , a detection ejector mechanism 200 , a circuit board 300 , a card tray 400 and a card holder 500 .

[0016] An electronic device generally includes a case, which can provide a mounting position for a card tray / card holder device and can also provide protection for the card tray / card holder device. A circuit board 300 is generally fixed in the case, which is the base of the card tray / card holder device, and the card retainer cover 100, the detection / ejector mechanism 200, the card tray 400 and the card holder 500 are directly or indirectly mounted on the circuit board 300. Optionally, the circuit board 300 can be a motherboard of an electronic device, or of course a sub-board of an electronic device, or of course another circuit board in an electronic device, and the embodiments of the present application are not limited thereto.

[0017] The card holder 500 is electrically connected to the circuit board 300, and further realizes a power supply connection and a communication connection between the circuit boards 300. The card holder 500 may be directly fixed to the circuit board 300 by a patch process, or of course, the card holder 500 may be installed on the card retaining cover 100 and indirectly fixed to the circuit board 300 via the card retaining cover 100, or of course, the card holder 500 may indirectly realize an electrical connection between the card holder 500 and the circuit board 300 via the card retaining cover 100.

[0018] In the embodiment of the present application, the card retaining cover 100 is fixed to the circuit board 300, and the card retaining cover 100 forms the main supporting frame of the card tray card holder device together with the circuit board 300. The card retaining cover 100 may be fixed to the circuit board 300 by methods such as adhesion, locking, welding, connection with connecting members (e.g. rivets, screw members), etc., and the embodiment of the present application does not limit the specific fixing method between the card retaining cover 100 and the circuit board 300.

[0019] The card pressing cover 100 and the circuit board 300 form a first storage space, and the card tray 400 and the card holder 500 are both installed in the first storage space. The card tray 400 is used to carry a smart card 800, such as a SIM card. The card tray 400 can move to enter and exit the first storage space, and can also carry the smart card 800 to install or remove it. When the card tray 400 is located in the first storage space, the card tray 400 carrying the smart card 800 is fixed in the first storage space. The card pressing cover 100 can also press the smart card 800 placed on the card tray 400, so that the smart card 800 can be more stably electrically contacted with the card holder 500 and the stability of the fitting is ensured. In the embodiment of the present application, the card tray 400 includes a detection fitting portion 410 and a lever fitting portion 420.

[0020] The card tray 400 has an installed state and a removed state. When the card tray 400 is in the installed state, the card tray 400 is installed in the first storage space, and the smart card 800 placed on the card holder 500 can make electrical contact with the card holder 500, thereby realizing a communication connection between the smart card 800 and the circuit board 300 through the card holder 500, and in this case, the smart card 800 is installed through the card tray 400. When the card tray 400 is in the removed state, at least a part of the card tray 400 moves from within the first storage space to outside the first storage space, and the user can remove the smart card 800 by removing the card tray 400.

[0021] In the embodiment of the present application, the card tray 400 may hold one or more smart cards 800, and the card holder 500 may be one or more. Each card holder 500 may correspond to one smart card 800, so that each smart card 800 can easily realize communication between the circuit board 300 and each independent card holder 500. Of course, the embodiment of the present application does not limit the number of smart cards 800 and the card holder 500.

[0022] The detection ejector mechanism 200 is a mechanism for ejecting the card tray 400 and enabling the removal of the card tray 400, as well as a mechanism for detecting whether the card tray 400 is attached to a predetermined position or not; that is, it detects the state of the card tray, which in the embodiment of the present application includes an attached state and a removed state.

[0023] In the embodiment of the present application, the detection ejector mechanism 200 is stacked on the card retaining cover 100. Optionally, the circuit board 300, the card retaining cover 100 and the detection ejector mechanism 200 are sequentially installed in a direction perpendicular to the circuit board 300, and of course, the circuit board 300, the detection ejector mechanism 200 and the card retaining cover 100 may be sequentially installed in a direction perpendicular to the circuit board 300.

[0024] The detection ejector mechanism 200 is fixed to the card retaining cover 100, and is further indirectly fixed to the circuit board 300 via the card retaining cover 100, thereby achieving installation. In this case, the detection ejector mechanism 200 is directly installed on the circuit board 300, thereby avoiding occupying the board surface space of the circuit board 300.

[0025] The detection ejector mechanism 200 includes a lever 210 and a detection unit 220. The lever 210 is used to drive the driving card tray 400 to move and further realize removal of the card tray 400. The detection unit 220 is fitted into the detection fitting unit 410 and is used to detect the state of the card tray.

[0026] The lever 210 is pivotally mounted on the card retaining cover 100, and is thereby rotatable relative to the card retaining cover 100. In one alternative, the lever 210 is directly pivotally connected to the card retaining cover 100. In another alternative, the lever 210 is directly pivotally mounted on a protective cover 600, which will be described later, and may further be indirectly mounted on the card retaining cover 100 via the protective cover 600.

[0027] A pin hole is provided in the electronic device, and generally, the pin hole is opened in the case of the electronic device. The first end of the lever 210 is used to be installed opposite the pin hole. The pin hole allows the pin 900 to pass through, and the pin 900 pushes the first end of the lever 210, thereby realizing the rotation of the lever 210. The second end of the lever 210 is installed opposite the lever fitting part 420, and the second end of the lever 210 can rotate in a first direction together with the lever 210 and contact the lever fitting part 420, and the second end of the lever 210 can push the lever fitting part 420, thereby realizing the pushing of the entire card tray 400, thereby driving at least a part of the card tray 400 to move out of the first receiving space. Through the pushing action of the second end of the lever 210, the card tray 400 carries the smart card 800 out of the case, thereby achieving the purpose of removal.

[0028] Of course, during the installation process of the card tray 400, the user pushes the card tray 400, and the lever fitting portion 420 contacts the second end of the lever 210, and the second end pushes the lever 210 to rotate in the second direction, thereby realizing the return of the lever 210. It should be noted that the first direction is opposite to the second direction.

[0029] In the embodiment of the present application, the detection portion 220 is installed on the card retaining cover 100, and the detection portion 220 is installed corresponding to the detection fitting portion 410, and can further be fitted into the detection fitting portion 410, thereby used to detect the state of the card tray, and it should be noted that in this specification, the state of the card tray includes an installed state and a removed state.

[0030] The card tray card holder device disclosed in the embodiments of the present application improves upon the related technology by stacking the detection ejector mechanism 200 on the card holder cover 100, thereby ensuring the functionality of the detection ejector mechanism 200 itself, while avoiding the need to directly install the detection ejector mechanism 200 on the circuit board 300, and thus avoiding occupying space on the surface of the circuit board 300. Furthermore, it solves the problem of the card tray card holder device in the related technology occupying a relatively large space on the surface of the circuit board 300, resulting in a relatively low utilization rate of the space on the surface of the circuit board 300.

[0031] As mentioned above, the card retaining cover 100 can press the smart card 800 to make it more closely electrically contact with the card holder 500. In one optional solution, the card retaining cover 100 includes an elastically bent crimping portion 116, which is bent toward the first receiving space, so that the smart card 800 in the card tray 400 can be pressed after the card tray 400 is mounted in place, so that the electrical contact between the smart card 800 and the card holder 500 can be more stable. Optionally, the elastically bent crimping portions 116 are multiple and distributed in an array on the card retaining cover 100. Specifically, they may be distributed in an array on the cover body 110 described later.

[0032] Of course, the card holder cover 100 can also fix the card tray 400 and the smart card 800, so that the card tray 400 can be more stably held in the first receiving space without being subjected to external force. In one alternative solution, the card holder cover 100 may include a holding elastic arm 114, which may include an elastic protrusion, and the card tray 400 may have a positioning groove 400b1. During the process of mounting the card tray 400 in the first receiving space, the holding elastic arm 114 is elastically deformed, and the elastic protrusion is elastically locked in the positioning groove 400b1, so that the card tray 400 is fixed in the first receiving space. During the process of removing the card tray 400, the card tray 400 can be controlled to move in the removal direction, and the elastic protrusion is separated from the positioning groove 400b1, so that the card tray 400 can be removed.

[0033] In the process of installing the card tray 400, the user pushes the card tray 400 carrying the smart card 800 from the through hole in the case into the case, and in this process, due to the action of external force by the user, the card tray 400 pushes up the elastic protrusion until the positioning groove 400b1 moves to a position opposite the elastic protrusion, and as a result, the elastic protrusion is positioned and fitted into the positioning groove 400b1 by elastic force, thereby realizing the installation of the card tray 400 in the first accommodating space, and at the same time, the detection fitting portion 410 is fitted into the detection portion 220, and the detection portion 220 determines that the card tray 400 is installed in the specified position.

[0034] In the process of removing the card tray 400, the user uses the pin 900 to pass through the pin hole to push the first end of the lever 210, and then rotates the lever 210, so that the first end of the lever 210 rotates away from the pin hole, and the second end of the lever 210 is installed opposite the lever fitting part 420, and the rotation center of the lever 210 is located between its two ends, so that the second end of the lever 210 can rotate in a direction close to the through hole during rotation, so that the purpose of pushing the card tray 400 so that at least a part of it passes through the through hole and extends out of the case can be achieved by pushing the lever fitting part 420, and in this process, the thrust force applied by the lever 210 to the lever fitting part 420 can overcome the elastic force between the elastic protrusion and the positioning groove 400b1, thereby moving the card tray 400 out of the case. As a result, the user can pull out the card tray 400. In the process of the card tray 400 moving out of the case, the detection unit 220 is engaged with the detection engagement unit 410, so that it can determine that the card tray 400 is in the removed state.

[0035] In the embodiment of the present application, the card retaining cover 100 is generally fixed to the circuit board 300 by a welding method, and therefore the card retaining cover 100 may be provided with a weld fillet 118, which is welded and fitted to the circuit board 300, thereby achieving the purpose of increasing the weld area and improving the stability of the assembly.

[0036] In one alternative solution, the circuit board 300 may have a positioning hole 310 formed therein, and the card retaining cover 100 may include an insertion positioning portion 115 which is inserted into and fitted into the positioning hole 310, thereby further avoiding any misalignment that may occur to the card retaining cover 100 during welding, and further improving the assembly quality.

[0037] To facilitate installation of the card tray 400, the card retaining cover 100 may include a guide bend 119 that can be guided and fitted to the card tray 400, thereby making it easier for the card tray 400 to slide into the first housing space and making assembly easier.

[0038] In an embodiment of the present application, the card retaining cover 100 may be provided with a second observation hole 117, and the second observation hole 117 may be multiple, and the multiple second observation holes 117 are distributed in an array, so that the operator can easily view the assembly in the first storage space through the second observation hole 117.

[0039] In the embodiment of the present application, the card retainer cover 100 may include a cover body 110 and a connecting shaft 120 installed on the cover body 110, a pivot fitting hole 211 is opened on the lever 210, and the connecting shaft 120 is pivoted and fitted into the pivot fitting hole 211. In an alternative solution, the connecting shaft 120 may be a cylindrical connecting shaft, the pivot fitting hole 211 may be a circular hole, and the cylindrical connecting shaft is pivoted and fitted into the circular hole. Referring to Figures 10 to 11, in order to facilitate assembly, in an alternative solution, the end of the connecting shaft 120 may be provided with a corner chamfer or a R chamfer.

[0040] In another alternative solution, the cross-sectional shape of the connection shaft 120 may be elongated, and the pivot fitting hole 211 may be a strip-shaped hole. The connection shaft 120 is pivoted and fitted into the pivot fitting hole 211 within a preset angle range. In this case, the strip-shaped hole is fitted into the connection shaft 120 having an elongated cross-sectional shape, so that the lever 210 can be pivoted within a limited preset angle range, and can also meet the pivot angle of the lever 210 required for attaching and detaching the card tray 400. And the pivot fitting hole 211 is a strip-shaped hole, which has a relatively small effect on the strength of the lever 210. Optionally, the cross-sectional shape of the connection shaft 120 is rectangular. It should be noted that the cross-sectional shape of the connection shaft 120 refers to a cross section cut in a direction perpendicular to the axis of the connection shaft 120. The elongated shape has a length size and a width size, and the length size is larger than the width size.

[0041] Alternatively, the preset angle range may be 30°, 45°, etc., and a person skilled in the art may determine the preset angle range according to the rotation range of the lever 210 required when removing the card tray 400, and the embodiments of the present application do not limit the specific numerical values ​​of the preset angle range.

[0042] The connecting shaft 120 may be fixed to the cover body 110 by an assembly manner, for example, the connecting shaft 120 may be fixed to the cover body 110 by welding, interference fit locking, etc. Of course, the connecting shaft 120 and the cover body 110 may be an integrated structure, thus saving the assembly operation. Specifically, the connecting shaft 120 and the cover body 110 may be formed by injection molding, bending process or cutting process, and the present application is not limited thereto.

[0043] In one alternative solution, the connecting shaft 120 may be a sheet-like structure bent from the cover body 110, i.e., the connecting shaft 120 may be formed by tearing material from a blank used to form the cover body 110. Of course, in such a case, the cover body 110 will have tear holes formed in the area where the connecting shaft 120 will be formed. Such a structure is easy to form and saves material, without the need for a specially arranged connecting shaft 120 of a separate structure.

[0044] In a further technical solution, the card tray card holder device disclosed in the embodiments of the present application may further include a protective cover 600. The protective cover 600 is installed on the card retaining cover 100. The protective cover 600 and the card retaining cover 100 form a second accommodating space, and the lever 210 may be installed in the second accommodating space. The second accommodating space may be a protective space to protect the lever 210 and avoid interference of external parts with the movement of the lever 210. Of course, at least a part of the detection unit 220 may be located in the second accommodating space, and thus may be protected by the second accommodating space.

[0045] The lever 210 may include a curved flange 212, which is located at an edge of the lever 210 that is away from the lever fitting portion 420. The protective cover 600 may include an inner support side wall 610, which is supported by the card retainer cover 100 and located at a side of the lever 210 that is away from the pin hole. The curved flange 212 is rollingly fitted to the inner support side wall 610. During the rotation of the lever 210, the curved flange 212 corresponds to the pivot of the lever 210, which makes it easy for the lever 210 to rotate around the connecting shaft 120, and is favorable for the lever 210 to apply a thrust during the rotation. During the process of removing the card tray 400, the inner support side wall 610 can further be fitted to the lever 210 in a positionally restricted manner, which plays a role in limiting the rotation range of the lever 210 and preventing the lever 210 from rotating excessively and wastefully.

[0046] The protective cover 600 may further include an outer support side wall 620, which is supported by the card pressing cover 100. The outer support side wall 620 is located on a side facing the lever fitting portion 420 of the lever 210, and when the lever 210 rotates along a second direction, the outer support side wall 620 is positionally restricted and fitted to the lever 210, and the second direction is opposite to the first direction. In the process of mounting the card tray 400, the lever fitting portion 420 pushes the second end of the lever 210, thereby pushing the lever 210 to rotate (i.e., rotate along the second direction), and the lever 210 can be positionally restricted and fitted to the outer support side wall 620, thereby preventing the lever 210 from rotating excessively and further preventing the first end of the lever 210 from rotating excessively and moving away from the pin hole.

[0047] In the card tray card holder device disclosed in the embodiment of the present application, a first relief notch 111 is opened at an end of the card retainer cover 100 close to the lever 210, and a first thick portion 213 is provided at a first end of the lever 210, and the first thick portion 213 is located within the first relief notch 111. Due to the first thick portion 213, the area of ​​the second end of the lever 210 that is fitted into the lever fitting portion 420 is relatively large, so that the lever 210 pushes the lever fitting portion 420 more effectively, and the deformation / stick phenomenon caused by the small contact area between the second end of the lever 210 and the lever fitting portion 420 is avoided.

[0048] As described above, the detection unit 220 is used to detect the state of the card tray, which includes an attached state and a detached state. In the embodiment of the present application, there may be multiple types of the detection unit 220. The detection unit 220 may be an optical detection unit or an electrical detection unit. For example, when the detection unit 220 is an optical detection unit, the detection unit 220 can determine the state of the card tray by acquiring an image of the detection fitting unit 410.

[0049] In one alternative solution, when the card tray 400 is in an attached state, the detection fitting part 410 contacts the detection part 220. When the card tray 400 is in a detached state, the detection fitting part 410 separates from the detection part 220. In this case, the state of the card tray 400 is determined by judging whether the detection part 220 and the detection fitting part 410 contact each other, thereby achieving the purpose of detecting whether the card tray 400 is attached in a predetermined position. For example, the detection part 220 may be a self-capacitance plate, and after the detection fitting part 410 separates from the detection part 220, the capacitance value of the detection part 220 is a first capacitance value, and after the detection fitting part 410 contacts the detection part 220, the capacitance value of the detection part 220 is a second capacitance value, and the first capacitance value is not equal to the second capacitance value, and the state of the card tray can be determined by judging the capacitance value during the detection process.

[0050] In a further technical solution, the detection unit 220 may include a detection dome 221 and a detection terminal 222, one end of the detection dome 221 is connected to the protective cover 600 or the card retaining cover 100, the other end of the detection dome 221 is an electrical connection end, and the detection terminal 222 is installed on the protective cover 600 or the card retaining cover 100, when the card tray 400 is in a first state, the detection fitting unit 410 contacts the detection dome 221 and separates the electrical connection end from the detection terminal 222, when the card tray 400 is in a second state, the detection fitting unit 410 separates from the detection dome 221 and the electrical connection end electrically contacts the detection terminal 222. Here, one of the first state and the second state is a detached state, and the other is an attached state.

[0051] For example, the detection dome 221 may be a ground dome. In this case, the detection terminal 222 may be connected to a signal source, and when the detection terminal 222 contacts the electrical connection end, the signal of the detection terminal 222 is grounded through the detection dome 221, at this time, the electronic device can detect that the detection terminal 222 is at a low level signal, and when the detection terminal 222 is separated from the electrical connection end, the detection terminal 222 is not grounded through the electrical connection end, at this time, the electronic device can detect that the detection terminal 222 is at a high level signal. In a specific detection process, the electronic device can determine the state of the card tray by obtaining whether the level signal of the detection terminal 222 is a high level signal or a low level signal. It should be explained that in this specification, the low level signal and the high level signal are relative concepts, and the embodiments of the present application do not limit the specific values ​​of the low level signal and the high level signal.

[0052] In one alternative solution, the first state is a removed state and the second state is an attached state, in this case, during the process of removing the card tray 400, as the card tray 400 is gradually moved out of the first receiving space, the detection fitting 410 gradually contacts the detection dome 221, causing the detection dome 221 to separate from the detection terminal 222, thereby cutting off the electrical connection between the detection dome 221 and the detection terminal 222, so that the circuit detects this state as the removed state. During the process of assembling the card tray 400, as the card tray 400 gradually enters the first receiving space, the detection fitting 410 gradually separates from the detection dome 221, and the detection dome 221 recovers to a state in which it contacts the detection terminal 222 due to the action of elastic recovery force, in this case the detection dome 221 is electrically connected to the detection terminal 222, so that the circuit detects this state as the attached state.

[0053] In another alternative solution, the first state is the installed state and the second state is the removed state, in this case, during the process of removing the card tray 400, as the card tray 400 is gradually moved out of the first receiving space, the detection fitting part 410 gradually separates from the detection dome 221, and the detection dome 221 recovers to a position where it contacts the detection terminal 222 due to the action of elastic recovery force, and an electrical connection is formed between the detection dome 221 and the detection terminal 222, so that this state is determined as the installed state by the circuit detection. During the process of assembling the card tray 400, as the card tray 400 gradually enters the first receiving space, the detection fitting part 410 gradually contacts the detection dome 221, pushing the detection dome 221 to deform, and then separates from the detection terminal 222, thereby cutting off the electrical connection between the detection dome 221 and the detection terminal 222, and then the circuit detection determines this state as the removed state.

[0054] In the embodiment of the present application, at least one of the card retainer cover 100 and the protective cover 600 may have a dustproof hole 112, which is disposed opposite the detection unit 220 and communicates with the second accommodating space. As described above, the detection unit 220 includes a detection dome 221 and a detection terminal 222, and during the process of mounting and dismounting the card tray 400, the detection dome 221 and the detection terminal 222 switch between contact and separation. In order to prevent foreign matter such as dust from accumulating between the detection dome 221 and the detection terminal 222 and causing the detection dome 221 and the detection terminal 222 to form a constant contact mode, the dustproof hole 112 may communicate with the second accommodating space and be disposed opposite the detection unit 220, so that the dust accumulated between the detection dome 221 and the detection terminal 222 in the second accommodating space can escape, thereby avoiding accumulation.

[0055] An insulating part 700 may be fixed in the second receiving space, and optionally, the insulating part 700 may be a plastic part injection molded on the protective cover 600. The detection terminal 222 is fixed to the insulating part 700, and the detection terminal 222 is connected to the protective cover 600 through the insulating part 700 while being insulated. In a further technical solution, the protective cover 600 may include a first positioning barring 640 and a second positioning barring 650, and the first positioning barring 640 and the second positioning barring 650 may intersect, specifically, the first positioning barring 640 may be perpendicular to the second positioning barring 650. In order to improve the stability of the connection with the protective cover 600, the plastic part may be injection molded on the first positioning barring 640 and the second positioning barring 650.

[0056] In the embodiment of the present application, the card retaining cover 100 may be provided with a second relief notch 113, and at least a portion of the detection dome 221 may extend into the second relief notch 113. In such a case, at least a portion of the detection dome 221 may be accommodated by the second relief notch 113, thereby making the assembly between the detection dome 221 and the card retaining cover 100 more compact.

[0057] In a further technical solution, the detection dome 221 may be provided with a second thickened portion 2211, and at least a portion of the second thickened portion 2211 extends into the second relief notch 113. Since at least a portion of the second thickened portion 2211 can be accommodated in the second relief notch 113, the above structure facilitates forming a larger contact surface with the detection dome 221 without changing the overall size of the electronic device, thereby making the fit between the detection dome 221 and the detection terminal 222 more stable.

[0058] In the embodiment of the present application, the detection dome 221 and the protective cover 600 may be an integrated structure, or the detection dome 221 and the card retaining cover 100 may be an integrated structure, or the detection dome 221 is assembled to the protective cover 600 or the card retaining cover 100. The integrated structure described above has the advantage of being easy to install.

[0059] In a further technical solution, the card retaining cover 100 or the protective cover 600 may be provided with a first observation hole 630 corresponding to the detection portion 220, and the first observation hole 630 can be used by an operator to observe the fitting status of the detection portion 220.

[0060] In the embodiment of the present application, the structure of the lever 210 may be various, and in one optional solution, the lever 210 may include a body 214 and a bent portion 215 disposed at an end of the body 214, the body 214 is pivotally fitted to the card retaining cover 100, the body 214 is located at a first side of the card retaining cover 100, and the bent portion 215 is located at a second side of the card retaining cover 100, the first side and the second side are adjacent sides of the card retaining cover 100, the stacking direction of the body 214 and the card retaining cover 100 is the thickness direction of the card tray 400, and the bent portion 215 is disposed opposite to the pin hole. In this case, the position of the bent portion 215 in the thickness direction of the electronic device is close to the position of the card tray 400 in the thickness direction of the electronic device, thereby alleviating the problem of the unevenness of the force applied to the card tray 400 when the bent portion 215 is pushed by the pin 900.

[0061] In a further technical solution, the main body 214 may be a first sheet-like structure, and the thickness direction of the first sheet-like structure coincides with the stacking direction of the card retainer cover 100 of the detection ejector mechanism 200. In such a case, it is advantageous to reduce the thickness of the card tray card holder device, and is advantageous for designing thin electronic devices.

[0062] In a further technical solution, the bending portion 215 may be a second sheet-like structure, and the thickness direction of the second sheet-like structure coincides with the moving direction of the card tray 400. In such a case, the region with a relatively large area of ​​the bending portion 215 faces the pin 900, which is advantageous in avoiding poor stability of the driving of the pin 900 relative to the lever 210 due to a relatively small mating area with the pin 900.

[0063] As described above, removal of the card tray 400 must be achieved by a user gripping the pin 900 and pushing the first end of the lever 210. During operation, in the process of a user pushing the first end of the lever 210 through the pin hole, the end of the pin 900 that contacts the lever 210 may slide and pierce a device in another part of the electronic device. Based on this, in one alternative solution, a stopper groove 2151 is provided on the surface facing the pin hole of the first end of lever 210, the groove opening of stopper groove 2151 faces the pin hole, and the bottom wall of stopper groove 2151 facing the groove opening is the pin acting surface. In the process of pushing the first end of lever 210 so as to rotate the pin, the end of pin 900 that contacts lever 210 extends into stopper groove 2151 and can be fitted into stopper groove 2151 by restricting its position. The stopping action of stopper groove 2151 can prevent malfunctions caused by the end of pin 900 sliding.

[0064] Of course, the electronic device disclosed in the embodiment of the present application may also solve the problem of piercing possibly caused by the pin 900 in other ways. In another alternative solution, the surface of the first end of the lever 210 facing the pin hole may be provided with an anti-slip structure, specifically, the anti-slip structure may be a frosted surface or an anti-slip pattern. In this case, the anti-slip structure may improve the friction coefficient between the lever 210 and the end of the pin 900, and reduce the probability that the end of the pin 900 will slide.

[0065] In the embodiment of the present application, the structure of the card tray 400 may be various. Specifically, the detection fitting portion 410 and the lever fitting portion 420 may both be protrusions formed on the card tray 400, that is, the detection fitting portion 410 is a first protrusion, and the lever fitting portion 420 is a second protrusion.

[0066] In a further technical solution, the card tray 400 may include a card tray cap 400a and a card tray body 400b, in which a locking groove for accommodating a smart card is provided, and a strip-shaped boss 400c protruding from the groove opening of the locking groove is provided on the side of the card tray cap 400a facing the card tray body 400b, and the strip-shaped boss 400c includes a detection fitting portion 410 and a lever fitting portion 420. With this structure, the structures of the detection fitting portion 410 and the lever fitting portion 420 are simpler.

[0067] Based on the card tray card holder device disclosed in the embodiments of the present application, the embodiments of the present application disclose an electronic device, and the disclosed electronic device includes the card tray card holder device described in the embodiments above.

[0068] In the embodiment of the present application, the case includes a cavity, a through hole and a pin hole, and the through hole and the pin hole are both connected to the cavity. The pin hole can be fitted with the pin 900 and used for the pin 900 to pass through and remove the card tray 400. The through hole can be used for the card tray 400 to pass through and further realize the installation and removal of the card tray 400.

[0069] Generally, the case includes an intermediate frame, and the through holes and pin holes may both be opened in the intermediate frame. During use of the electronic device (e.g., a mobile phone, a tablet computer), the intermediate frame generally does not face the user directly, so the through holes and pin holes are opened in the intermediate frame, which can improve the appearance performance of the electronic device and also improve the visual experience of the user.

[0070] The electronic devices disclosed in the embodiments of the present application may be devices such as mobile phones, tablet computers, e-book readers, wearable devices, game consoles, etc., and of course may be other types of devices, and the embodiments of the present application do not limit the specific types of electronic devices.

[0071] In the above embodiments of the present application, the emphasis is on the differences between the embodiments, and the optimization features of the differences between the embodiments can be combined to form a preferred embodiment, unless there is a contradiction, and for the sake of brevity, will not be described further here.

[0072] The above is only an embodiment of the present application, and is not intended to limit the present application. For those skilled in the art, the present application can be modified and changed in various ways. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application should be included within the scope of the claims of the present application.
