[0024] Hereinafter, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application, and it should be understood that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. Based on the embodiments of the present application, all other embodiments that can be obtained by those skilled in the art without any creative efforts shall fall within the protection scope of the present application.

[0025] The terms "first," "second," etc. in the specification and claims of this application are not intended to describe a particular order or precedence order, but rather to distinguish between similar objects. Terms used in this manner may be interchangeable in some cases, allowing the embodiments of this application to be practiced in an order other than that shown or described herein. Also, in the specification and claims, "and / or" indicates at least one of the connected objects, and the symbol " / " generally indicates that the related objects before and after are in an "or" relationship.

[0026] Hereinafter, as shown in FIGS. 1a to 6g, the card tray structure provided in the embodiments of the present application will be described in detail through specific embodiments and application scenarios.

[0027] The card tray structure of the embodiment of the present application includes a card tray. The card tray may have a first card slot 41 on one side and a second card slot 42 on the other side. The specific shapes and sizes of the first card slot 41 and the second card slot 42 can be selected according to actual needs. The card tray may include a tray body 40. The tray body 40 may be a frame body surrounded by a frame edge, and the frame body may be a quadrilateral frame body. A first platform portion 43 may be provided on one edge of the frame edge to form the first card slot 41. When a card is placed in the first card slot 41, it can abut against the first platform portion 43 to be stably positioned in the first card slot 41. A second platform portion 44 may be provided on the other edge of the frame edge to form the second card slot 42. When a card is placed in the second card slot 42, it can abut against the second platform portion 44 to be stably positioned in the second card slot 42.

[0028] 3a and 3b, the first card slot 41 is located on one side of the card tray, and the second card slot 42 is located on the other side of the card tray, and the first card slot 41 and the second card slot 42 may be offset from each other. A Subscriber Identity Module (SIM) card may be placed in the first card slot 41, and a Trans-flash (T-flash) card may be placed in the second card slot 42. There may be two first card slots 41 and one second card slot 42, and the card tray may simultaneously accept two SIM cards and one T-flash card, or any one or two cards may be selectively inserted.

[0029] In an embodiment of the present application, as shown in FIGS. 2 to 4a, the tray body 40 may be a quadrilateral frame such as a rectangle, and a first platform portion 43 may be provided on one edge of the frame to form a first card slot 41. A SIM card can be placed in the first card slot 41 and attached to the first platform portion 43, and the first platform portion 43 can support, restrict, and stabilize the SIM card. A second platform portion 44 may be provided on the other edge of the frame to form a second card slot 42. A T-flash card can be placed in the second card slot 42 and attached to the second platform portion 44, and the second platform portion 44 can support, restrict, and stabilize the T-flash card. This simplifies the overall structure of the card tray, reduces the volume and space it occupies, and is advantageous for achieving a slimmer design.

[0030] The card tray may further include a first connecting beam 51 and a second connecting beam 52. Both ends of the first connecting beam 51 may be connected to the frame edge, respectively, and the first connecting beam 51 can increase the strength of the card tray. The first connecting beam 51 and the second connecting beam 52 may be arranged parallel to each other and spaced apart, and there may be two first card slots 41, each of which may be located on either side of the first connecting beam 51, respectively, and the first connecting beam 51 can restrict SIM cards in the two first card slots 41. Both ends of the second connecting beam 52 may be connected to the frame edge, respectively, and the second connecting beam 52 can increase the strength of the card tray. The second card slot 42 may be defined by the second platform portion 44 and the second connecting beam 52, which is advantageous for reducing the volume of the entire structure. The first connecting beam 51 and the second card slot 42 may be arranged opposite each other, and when a card is placed in the second card slot 42, the first connecting beam 51 can provide a certain support and restriction to the card, preventing it from moving in the second card slot 42. The second connecting beam 52 and the first card slot 41 may be arranged opposite each other, and when a card is placed in the first card slot 41, the second connecting beam 52 can provide a certain support and restriction to the card, preventing it from moving in the first card slot 41 and ensuring that the card is stably placed in the card slot. The card tray may be integrally molded, which improves the overall structure and simplifies the manufacturing process.

[0031] In the card tray structure of the embodiment of the present application, the tray body 40 may be a frame body surrounded by a frame edge. The provision of the first connecting beam 51 and the second connecting beam 52 increases the overall strength of the card tray and makes it less likely to deform. The first connecting beam 51 is disposed opposite the second card slot 42. When a card is placed in the second card slot 42, the first connecting beam 51 can provide a certain level of support and restriction to the card, preventing it from moving through the second card slot 42. The second connecting beam 52 is disposed opposite the first card slot 41. When a card is placed in the first card slot 41, the second connecting beam 52 can provide a certain level of support and restriction to the card, preventing it from moving through the first card slot 41. The first connecting beam 51 and the second connecting beam 52 can increase the strength of the card tray and provide a certain level of support and restriction for the card in the card slot, eliminating the need for a steel plate and allowing the thickness of the card tray to be thin. When the card holder and the card tray are mated, the overall thickness is small and the space occupied is small, which is advantageous for designing thinner and more compact devices and improving the user experience.

[0032] In some embodiments, the surface of the first connecting beam 51 facing the second card slot 42 is flat and flush with the surface of the second platform portion 44. That is, the first connecting beam 51 and the second card slot 42 may be disposed opposite each other, and the surface of the first connecting beam 51 facing the second card slot 42 may be flat and flush with the surface of the second platform portion 44. The surface of the first connecting beam 51 facing the second card slot 42 can support the T-flash card in the second card slot 42 and restrict the T-flash card from floating up and down.

[0033] Optionally, as shown in FIGS. 2 to 4d, the surface of the second connecting beam 52 facing the first card slot 41 is flat and flush with the surface of the first platform portion 43. The surface of the second connecting beam 52 facing the first card slot 41 can support the SIM card in the first card slot 41 and restrict the SIM card from floating up and down. The first connecting beam 51 and the second connecting beam 52 increase the overall strength of the card tray, support and stabilize the card, and eliminate the need for an additional steel plate in the middle layer of the card tray, which is advantageous for slimming down and can reduce the overall thickness by 0.1 mm or more. During manufacturing, the tray body 40, the first connecting beam 51, and the second connecting beam 52 can be integrally molded, improving the overall integrity and simplifying the manufacturing process.

[0034] In some embodiments, the card tray may further include a limit stopper 60, which may be provided on the edge of the frame rim of the tray body 40 or on the outer edge of the frame rim of the tray body 40. When the tray body of the card tray is inserted into the receiving groove of the card holder, the limit stopper 60 can limit its position, making it easier to remove the tray body from the receiving groove.

[0035] Optionally, as shown in Figures 2 to 3d and 4a, a sealing member 61 may be provided on the side of the limit stopper 60 close to the frame edge, and the sealing member 61 may be an elastic member, for example, a silicone ring. The sealing member 61 has a sealing effect, enabling waterproofing and dustproofing.

[0036] Optionally, the sealing member 61 extends to the inside of the second card slot 42, and a rib 62 is formed on the inner wall of the second card slot 42, and the rib 62 and the sealing member 61 may be integrally formed, thus reducing the space occupied.

[0037] In some embodiments, ribs 62 may be provided on the inner walls of the first card slot 41 and the second card slot 42. The ribs 62 can apply force to cards placed in the first card slot 41 and the second card slot 42, making it difficult for the cards to fall out. The ribs 62 may be made of elastic rubber and occupy a small volume, which is advantageous for reducing the overall space of the card tray and card holder and achieving a compact device. A portion of the sealing member 61 may extend toward the card slot to form the rib 62 on the inner wall of the second card slot 42. The sealing member 61 and the rib 62 may be made of a silicone material. When a card is inserted into the second card slot 42, the rib 62 interferes with the card and applies a pressing force to prevent the card from falling out, resulting in a simpler structure and a smaller space-consuming design. In manufacturing, the ribs 62 on the inner wall of the second card slot 42 and the sealing member 61 may be integral, and can be manufactured using the same mold and the same gate, without additional costs. For the SIM cards in the two first card slots 41, ribs 62 made of silicone material can be used to press the cards together, and the SIM cards in the two first card slots 41 can share one silicone block to form the ribs 62, or can share a waterproof silicone ring and a mold, which only requires adding one gate to fabricate, and the structure is simple and compact.

[0038] An embodiment of the present application provides a card tray assembly including the card tray structure described in the previous embodiment and a card holder. The card tray structure is mounted on the card holder and is detachably mounted on the card holder. Due to the high strength of the card tray, a steel plate is not required, and the thickness of the card tray can be reduced. When the card holder and the card tray structure are mated, the overall thickness is small and the occupied space is small, which is advantageous for the design of thinner and more compact devices and improves the user experience.

[0039] As shown in FIGS. 1a to 1d and 5b, the card holder may include a holder body 10, an ejection mechanism 13, and a detection mechanism. The holder body 10 is provided with a terminal 11, and may include an upper holder body 18 and a lower holder body 19. The upper holder body 18 and the lower holder body 19 are connected to each other, and the upper holder body 18 may be a metal shell such as an iron shell. A receiving groove may be defined between the upper holder body 18 and the lower holder body 19, and a card tray with a card loaded therein may be placed in the receiving groove. As shown in FIGS. 1a to 1d, the terminals may include an upper terminal 14 and a lower terminal 15. The lower holder body 19 may include a lower plastic body 17 and a lower terminal 15 provided on the lower plastic body 17. The upper terminal 14 may be provided on the upper holder body 18. The upper holder body 18 may be provided with an upper plastic body 16, and the upper terminal 14 may be provided on the upper plastic body 16. The push-out mechanism 13 may be provided in the holder body 10. The detection mechanism may include a resilient arm 20, one end of which is connected to the holder body 10 and the other end of which is spaced apart from the holder body 10. The push-out mechanism 13 can drive and move the other end of the resilient arm 20. When the push-out mechanism 13 is in a first state, the other end of the resilient arm 20 abuts against the terminal 11 and can be electrically connected to the terminal 11. When the push-out mechanism 13 is in a second state, the push-out mechanism 13 can drive the other end of the resilient arm 20 to move away from the terminal 11. When a card tray engages with the holder body 10, the push-out mechanism 13 can be driven to move the card tray to the second state, so that the other end of the resilient arm 20 is disconnected from the terminal 11. The push-out mechanism 13 can be driven to switch between the first state and the second state depending on the inserted card tray.

[0040] One end of the elastic arm 20 is connected to the holder body 10. The other end of the elastic arm 20 is driven and moved by the push-out mechanism 13, so that the other end of the elastic arm 20 abuts against or separates from the terminal 11, thereby establishing or breaking electrical contact with the terminal 11, thereby enabling the detection function of the detection mechanism. During use, when a card tray is inserted and in use, the push-out mechanism 13 can be driven to place the card tray in the second state, driving the other end of the elastic arm 20 so that it separates from the terminal 11, thereby completing the detection function. The reaction force of the other end of the elastic arm 20 firmly holds the push-out mechanism 13, preventing shaking and noise. Because this reaction force does not act on the card tray, a decrease in the card tray's holding force is avoided, preventing the card tray from coming loose when the mobile phone is dropped, and ensuring stable engagement between the card tray and the card holder.

[0041] In some embodiments, as shown in Figures 5a to 5f, the elastic arm 20 may be provided close to the edge of the holder body 10, or may extend along the edge of the holder body 10, thereby allowing the elastic arm 20 to cooperate with the pushing mechanism 13, the pushing mechanism 13 to drive and move the other end of the elastic arm 20, and further allowing the other end of the elastic arm 20 to abut against or move away from the terminal.

[0042] In another embodiment, as shown in FIGS. 5b, 5e, and 6a to 6e, the pushing mechanism 13 may include a rotating rod 30 rotatably connected to the holder body 10. The rotating rod 30 may be provided adjacent to an edge of the holder body 10 or may be rotatably connected via a pivot shaft or a screw. One end of the rotating rod 30 may be connected to the other end of the elastic arm 20. Movement of one end of the rotating rod 30 drives and moves the other end of the elastic arm 20, allowing the other end of the elastic arm 20 to abut against or separate from the terminals 11. When the pushing mechanism 13 is in the second state, the one end of the rotating rod 30 can drive the other end of the elastic arm 20 so that it moves away from the terminals 11. When a card tray is inserted, the pushing mechanism 13 can be driven to move the card tray to the second state. Depending on the state of the card tray insertion, the state of the pushing mechanism 13 can be controlled to control the other end of the elastic arm 20 to abut against or separate from the terminals 11, thereby establishing or breaking electrical contact with the terminals 11. The elastic arm 20 may include a first elastic arm 201 and a second elastic arm 202. The lower end of the first elastic arm 201 may be connected to the holder body 10, and the lower end of the second elastic arm 202 may be connected to the first elastic arm 201. The second elastic arm 202 may be located on the opposite side of the first elastic arm 201 from the rotating rod 30, and the upper end of the second elastic arm 202 may be spaced apart from the first elastic arm 201. The rotating rod 30 can drive the first elastic arm 201 to move. As the rotating rod 30 slides downward along the first elastic arm 201, the upper end of the first elastic arm 201 and the second elastic arm 202 move away from the terminal 11. During movement, the second elastic arm 202 increases the acting force to firmly press the ejection mechanism 13, preventing shaking and noise generation, preventing the card tray from coming loose when the mobile phone is dropped, and ensuring stable engagement between the card tray and the card holder.The curvature of the first elastic arm 201 and the second elastic arm 202 may be different, which allows the arc-shaped side of the rotating rod 30 to slide more smoothly, and when the second elastic arm 202 is pushed out, the first elastic arm 201 is also pushed out to an appropriate distance, so that the rotating rod 30 drives the elastic arms more stably.

[0043] 5a to 6e, the extrusion mechanism 13 may further include a push rod 31 having one end connected to the other end of the rotating rod 30, and the push rod 31 may extend along the edge of the holder body 10, and the push rod 31 can move and rotate the rotating rod 30 when moving. The push rod 31 can move and rotate the rotating rod 30, and can drive the other end of the elastic arm 20 so that the rotating rod 30 moves away from the terminal 11.

[0044] In some embodiments, as shown in Figures 6b and 6e, one end of the rotating rod 30 has an arcuate surface, which abuts against the other end of the elastic arm 20, and during driving, the one end of the rotating rod 30 may slide relative to the other end of the elastic arm 20 so that the one end of the rotating rod 30 can drive the other end of the elastic arm 20.

[0045] Optionally, one end of the rotating rod 30 may be provided with a sliding groove, and the other end of the elastic arm 20 may be movably provided in the sliding groove, so that the one end of the rotating rod 30 can slide stably relative to the other end of the elastic arm 20, and thus the rotating rod 30 can be prevented from slipping off.

[0046] Optionally, a slide groove is provided at the other end of the elastic arm 20, the slide groove extending along the longitudinal direction of the elastic arm 20, and one end of the rotating rod 30 is movably provided in the slide groove, so that the one end of the rotating rod 30 can slide stably relative to the other end of the elastic arm 20, and thus the rotating rod 30 does not slip off.

[0047] In an embodiment of the present application, as shown in Figures 6e and 6g, a contact bump 21 may be provided in the area where the other end of the elastic arm 20 abuts against the terminal 11, and the contact bump 21 may be one or more, and the contact bump 21 allows the other end of the elastic arm 20 to stably contact the terminal 11.

[0048] In application, the resilient arm 20 in the detection mechanism may be designed to be located on the side of the rotating rod 30 and driven by the rotating rod 30, and the card holder is directly driven in the insertion direction by the card tray. The terminal may be designed opposite the other end of the resilient arm 20 and may be covered with plastic, exposing a metal contact wall. When a card tray is not inserted, the rotating rod 30 and the second resilient arm 202 of the resilient arm 20 may be separated, and the other end of the resilient arm 20 may apply a pressing force to the terminal, allowing the contact bump 21 at the end of the resilient arm to stably contact the contact wall of the terminal, thereby closing the detection switch. When a card tray is inserted, the rotating rod 30 is pressed by the card tray and rotates, driving the other end of the resilient arm 20. When the card tray is inserted to the bottom, the other end of the resilient arm 20 is driven to completely separate, causing the contact bump to separate from the terminal, opening the detection switch, and completing the detection function.

[0049] Optionally, an insulating layer may be provided between the holder body 10 and the terminal 11. The insulating layer may be a plastic layer, and the insulating layer can prevent short-circuiting between the terminal 11 and the holder body 10. The insulating layer may be an elastic layer that has a buffering effect and can reduce damage to the terminal 11.

[0050] Optionally, the holder body 10 may be provided with a receiving groove, and the card tray is removably provided in the receiving groove. The card tray further includes a limiting stopper 60, which may be provided on the edge of the frame of the tray body 40, with at least a portion of the limiting stopper 60 located outside the receiving groove. When the tray body of the card tray is inserted into the receiving groove, the limiting stopper 60 can limit its position, making it easier to remove the tray body from the receiving groove. When the card tray engages with the holder body 10, such as when the tray body of the card tray is inserted into the receiving groove, the ejection mechanism 13 can be driven to move the card tray into the second state.

[0051] During use, the state of the ejection mechanism 13 can be changed depending on the state of the card tray in the holder body. The card tray can drive the ejection mechanism 13 to the second state, which drives and moves the other end of the elastic arm 20 so that the other end of the elastic arm 20 abuts or separates from the terminal 11, thereby establishing or breaking electrical contact with the terminal 11, thereby enabling the detection function of the detection mechanism. During use, when a card tray is inserted and in use, the ejection mechanism 13 can be driven to move the card tray to the second state, which drives the other end of the elastic arm 20 to separate from the terminal 11, thereby completing the detection function. The reaction force of the other end of the elastic arm 20 firmly holds the ejection mechanism 13, preventing shaking and noise. Because this reaction force does not act on the card tray, a decrease in the card tray's holding force is avoided, preventing the card tray from coming loose when the mobile phone is dropped, and ensuring stable engagement between the card tray and the card holder.

[0052] The embodiments of the present application provide an electronic device including the card tray assembly described in the embodiments. In the electronic device having the card tray assembly of the embodiments, when the card holder and the card tray are mated, the overall thickness is small, which is advantageous for designing a thinner and more compact device and improves the user experience.

[0053] Although the examples of the present application have been described above with reference to the drawings, the present application is not limited to the above-mentioned specific embodiments, which are merely illustrative and not limiting. Based on the suggestions of the present application, many forms that a person skilled in the art can make without departing from the spirit of the present application and the scope of protection of the claims are all within the scope of protection of the present application.
