It may be understood that data used in such a way is interchangeable in proper circumstances, so that the embodiments of this application described herein can be implemented in other sequences than the sequence illustrated or described herein. In addition, “and/or” in this specification and the claims represents at least one of the connected objects, and the character “/” generally represents an “or” relationship between the associated objects.

A card tray structure provided in the embodiments of this application is described below through specific embodiments and application scenarios thereof with reference to the accompanying drawings as shown in FIG. 1a to FIG. 6g.

The card tray structure in the embodiments of this application includes a card tray. One side of the card tray may be provided with a first card slot 41, and an other side of the card tray may be provided with a second card slot 42. The specific shapes and sizes of the first card slot 41 and the second card slot 42 may be selected based on actual needs. The card tray may include a supporting body 40. The supporting body 40 may be a frame enclosed by a frame edge. The frame may be a quadrangular frame. A first platform portion 43 may be arranged at an edge on one side of the frame edge to form the first card slot 41. In a case that a card is placed in the first card slot 41, the card may stop against the first platform portion 43, so that the card is stably placed in the first card slot 41. A second platform portion 44 may be arranged at an edge on the other side of the frame edge to form the second card slot 42. In a case that a card is placed in the second card slot 42, the card may stop against the second platform portion 44, so that the card is stably placed in the second card slot 42.

As shown in FIG. 3a and FIG. 3b, the first card slot 41 is located on one side of the card tray, and the second card slot 42 is located on an other side of the card tray. The first card slot 41 and the second card slot 42 may be arranged in a staggered manner. 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. Two SIM cards and one T-flash card may be placed into the same card tray, or any one or two cards may be selected and placed into the same card tray.

In the embodiments of this application, as shown in FIG. 2 to FIG. 4a, the supporting body 40 may be the quadrangular frame, for example, a rectangular frame. The first platform portion 43 may be arranged at an edge on one side of the frame edge to form the first card slot 41. The SIM card may be placed in the first card slot 41, and the SIM card may be attached to the first platform portion 43. The first platform portion 43 may support the SIM card and may limit the SIM card, to make the SIM card stable. The second platform portion 44 may be arranged at an edge on an other side of the frame edge to form the second card slot 42. The T-flash card may be placed in the second card slot 42, and the T-flash card may be attached to the second platform portion 44. The second platform portion 44 may support the T-flash card and may limit the T-flash card, to make the T-flash card stable. The card tray has a simple overall structure and a volume that consumes a small space, which is conducive to thinning.

The card tray may include a first connecting beam 51 and a second connecting beam 52. Two ends of the first connecting beam 51 may be connected to the frame edge respectively. The first connecting beam 51 may enhance the strength of the card tray. The first connecting beam 51 and the second connecting beam 52 may be arranged in parallel and spaced apart. There may be two first card slots 41. The two first card slots 41 may be located on two sides of the first connecting beam 51 respectively. The SIM cards in the two first card slots 41 may be limited by the first connecting beam 51. Two ends of the second connecting beam 52 may be connected to the frame edge respectively. The second connecting beam 52 may enhance the strength of the card tray. The second platform portion 44 and the second connecting beam 52 may define the second card slot 42, which is conducive to reducing the volume of the overall structure. The first connecting beam 51 may be arranged correspondingly to the second card slot 42. In a case that a card is placed in the second card slot 42, the card may be supported and limited by the first connecting beam 51, and may be prevented from being moved in the second card slot 42. The second connecting beam 52 may be arranged correspondingly to the first card slot 41. In a case that a card is placed in the first card slot 41, the card may be supported and limited by the second connecting beam 52, and may be prevented from being moved in the first card slot 41, so that the card is placed in the card slot stably. The card tray may be integrally formed to enhance integrity and simplify a manufacturing process.

In the card tray structure of the embodiments of this application, the supporting body 40 may be the frame enclosed by the frame edge. The first connecting beam 51 and the second connecting beam 52 may be arranged to enhance the overall strength of the card tray, and the card tray is not easily deformed. The first connecting beam 51 is arranged correspondingly to the second card slot 42. In a case that a card is placed in the second card slot 42, the card may be supported and limited by the first connecting beam 51, and may be prevented from being moved in the second card slot 42. The second connecting beam 52 is arranged correspondingly to the first card slot 41. In a case that a card is placed in the first card slot 41, the card may be supported and limited by the second connecting beam 52, and may be prevented from being moved in the first card slot 41. The first connecting beam 51 and the second connecting beam 52 may enhance the strength of the card tray, and may also support and limit a card in the card slot. There is no need to arrange a steel sheet, so that a thickness of the card tray may be reduced. During cooperation, a card holder and the card tray have a small overall thickness and consume a small space, which is conducive to the thinning and miniaturization design of the device and improves user experience.

In some embodiments, a surface of a side of the first connecting beam 51 facing the second card slot 42 is planar and coplanar with a surface of the second platform portion 44. That is, the first connecting beam 51 may be arranged correspondingly to the second card slot 42. The surface of the side of the first connecting beam 51 facing the second card slot 42 is planar and coplanar with the surface of the second platform portion 44. The surface of the side of the first connecting beam 51 facing the second card slot 42 may support the T-flash card in the second card slot 42 and may limit the T-flash card, to prevent the T-flash card from floating up and down.

Optionally, as shown in FIG. 2 to FIG. 4d, a surface of a side of the second connecting beam 52 facing the first card slot 41 is planar and coplanar with a surface of the first platform portion 43. The surface of the side of the second connecting beam 52 facing the first card slot 41 may support the SIM card in the first card slot 41 and may limit the SIM card, to prevent the SIM card from floating up and down. The first connecting beam 51 and the second connecting beam 52 may enhance the overall strength of the card tray and may support the card, to make the card stable. There is no need to add a steel sheet to a middle layer of the card tray, which is conducive to thinning, so that an overall thickness may be reduced by more than 0.1 mm. In a manufacturing process, the supporting body 40, the first connecting beam 51, and the second connecting beam 52 may be integrally formed, which is conducive to enhancing integrity and simplifies the manufacturing process.

In some embodiments, the card tray may further include: a limiting baffle 60. The limiting baffle 60 may be arranged on the edge of the frame edge of the supporting body 40, or may be arranged on an outer edge of the frame edge of the supporting body 40, so that in a case that the supporting body of the card tray is inserted into an accommodating groove of the card holder, the supporting body may be limited by the limiting baffle 60, to facilitate removing the supporting body from the accommodating groove.

Optionally, as shown in FIG. 2 to FIG. 3d and FIG. 4a, a sealing member 61 may be arranged on a side of the limiting baffle 60 close to the frame edge. The sealing member 61 may be an elastic member. For example, the sealing member 61 may be a silicone ring. The sealing member 61 may have a sealing effect and can prevent water and dust.

Optionally, the sealing member 61 extends into the second card slot 42 and forms a convex rib 62 on an inner side wall of the second card slot 42. The convex rib 62 and the sealing member 61 may be integrally formed, which can reduce a consumed space.

In some embodiments, convex ribs 62 may be arranged on inner side walls of the first card slot 41 and the second card slot 42. Forces may be applied to cards placed on the first card slot 41 and the second card slot 42 by the convex ribs 62, to prevent the cards from being easily to removed. The convex rib 62 may be an elastic rubber, consumes a small volume, and reduces an overall space of the card tray and the card holder, which is conducive to miniaturization of a device. A part of the sealing member 61 may extend toward the card slot to form the convex rib 62 on an inner side wall of the second card slot 42. The sealing member 61 and the convex rib 62 may be made of a silicone material. In a case that the card is placed in the second card slot 42, the convex rib 62 interferes with the card to provide a pressure to support the card and prevent the card from falling, which simplifies the structure and reduces the consumed space. In manufacturing, the convex rib 62 on the inner side wall of the second card slot 42 and the sealing member 61 may be integrated, and may be made by using a same mold and a same gate without additional costs. For SIM cards in the two first card slots 41, the convex rib 62 made of a silicone material may be used to support the cards. For the SIM cards in the two first card slots 41, the convex rib 62 may be formed by sharing one silicone block, or may be formed by sharing a mold with a waterproof silicone ring and by adding only one gate, which leads to a simple and compact structure.

An embodiment of this application provides a card tray assembly, including: the card tray structure and the card holder described in the foregoing embodiment. The card tray structure is arranged on the card holder, and the card tray structure may be detachably arranged on the card holder. The card tray has high strength, and there is no need to arrange a steel sheet, so that a thickness of the card tray may be reduced. During cooperation, the card holder and the card tray structure have a small overall thickness and consume a small space, which is conducive to the thinning and miniaturization design of the device and improves user experience.

As shown in FIG. 1a to FIG. 1d and FIG. 5b, the card holder may include: a seat body 10, an ejection mechanism 13, and a detection mechanism. A terminal 11 is arranged on the seat body 10. The seat body 10 may include an upper seat body 18 and a lower seat body 19. The upper seat body 18 is connected to the lower seat body 19. The upper seat body 18 may be a metal shell, for example, an iron shell. An accommodating groove may be defined between the upper seat body 18 and the lower seat body 19, and a card tray with a card may be placed in the accommodating groove. As shown in FIG. 1a to FIG. 1d, the terminal may include an upper terminal 14 and a lower terminal 15. The lower seat body 19 may include a lower plastic body 17 and the lower terminal 15 arranged on the lower plastic body 17. The upper terminal 14 may be arranged on the upper seat body 18. An upper plastic body 16 may be arranged on the upper seat body 18, and the upper terminal 14 may be arranged on the upper plastic body 16. The ejection mechanism 13 may be arranged on the seat body 10. The detection mechanism may include an elastic arm 20. One end of the elastic arm 20 is connected to the seat body 10, and an other end of the elastic arm 20 may be spaced apart from the seat body 10. The ejection mechanism 13 may drive the other end of the elastic arm 20 to move. In a case that the ejection mechanism 13 is in a first state, the other end of the elastic arm 20 stops against the terminal 11, and the other end of the elastic arm 20 may be electrically communicated with the terminal 11. In a case that the ejection mechanism 13 is in a second state, the ejection mechanism 13 may drive the other end of the elastic arm 20 to detach from the terminal 11. In a case that the card tray is clamped on the seat body 10, the card tray may drive the ejection mechanism 13 to be in the second state, so that the other end of the elastic arm 20 is disconnected from the terminal 11, and the inserted card tray may drive the ejection mechanism 13 to switch between the first state and the second state.

One end of the elastic arm 20 is connected to the seat body 10, and the ejection mechanism 13 may drive the other end of the elastic arm 20 to move. Further, the other end of the elastic arm 20 stops against or is detached from the terminal 11, so that the other end of the elastic arm 20 is electrically communicated with or disconnected from the terminal 11, to enable the detection mechanism to implement a detection function. During use, in a case that the card tray is inserted to enter a use state, the card tray may drive the ejection mechanism 13 to be in the second state, and the ejection mechanism 13 drives the other end of the elastic arm 20 to detach from the terminal 11, thereby implementing the detection function. A reaction force at the other end of the elastic arm 20 presses the ejection mechanism 13 tightly to prevent the ejection mechanism 13 from shaking and making noise. Since the reaction force does not act on the card tray, the holding force of the card tray can be prevented from being weakened, which prevents the card tray from falling out when the phone is dropped, and ensures the stability of the cooperation between the card tray and the card holder.

In some embodiments, as shown in FIG. 5a to FIG. 5f, the elastic arm 20 may be arranged adjacent to an edge of the seat body 10, and the elastic arm 20 may extend along the edge of the seat body 10, to facilitate cooperation between the elastic arm 20 and the ejection mechanism 13, so that the ejection mechanism 13 can drive the other end of the elastic arm 20 to move, to enable the other end of the elastic arm 20 to stop against or detach from the terminal.

In some other embodiments, as shown in FIG. 5b, FIG. 5e, and FIG. 6a to FIG. 6e, the ejection mechanism 13 may include: a rotating rod 30. The rotating rod 30 is rotatably connected to the seat body 10. The rotating rod 30 may be arranged adjacent to the edge of the seat body 10 and may be rotatably connected through a rotating 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 the one end of the rotating rod 30 may drive the other end of the elastic arm 20 to move, to enable the other end of the elastic arm 20 to stop against or detach from the terminal. In a case that the ejection mechanism 13 is in the second state, one end of the rotating rod 30 may drive the other end of the elastic arm 20 to detach from the terminal 11. In a case that the card tray is inserted, the card tray may drive the ejection mechanism 13 to be in the second state. A state of the ejection mechanism 13 may be controlled by a state of the inserted card tray, and further, the other end of the elastic arm 20 may be controlled to stop against or detach from the terminal 11, so that the other end of the elastic arm 20 is electrically communicated with or disconnected from the terminal 11. The elastic arm 20 may include a first elastic arm 201 and a second elastic arm 202. A lower end of the first elastic arm 201 may be connected to the seat body 10, a lower end of the second elastic arm 202 may be connected to the first elastic arm 201, and the second elastic arm 202 may be located on a side of the first elastic arm 201 facing away from the rotating rod 30. An upper end of the second elastic arm 202 may be spaced apart from the first elastic arm 201, and the rotating rod 30 may drive the first elastic arm 201 to move. As the rotating rod 30 slides downward along the first elastic arm 201, an 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 may increase an acting force to press the ejection mechanism 13 tightly, which prevents the ejection mechanism 13 from shaking and making noise, prevents the card tray from falling out when a mobile phone drops, and ensures stability of the cooperation between the card tray and the card holder. Bending radians of the first elastic arm 201 and the second elastic arm 202 may be different, so that an arc-shaped edge of the rotating rod 30 can slide more smoothly and ejects the first elastic arm 201 by a suitable distance while ejecting the second elastic arm 202, so that the rotating rod 30 can drive the elastic arm more stably.

In the embodiments of this application, as shown in FIG. 5a to FIG. 6e, the ejection mechanism 13 may further include: an ejector rod 31. One end of the ejector rod 31 is connected to the other end of the rotating rod 30, and the ejector rod 31 may extend along the edge of the seat body 10. In a case that the ejector rod 31 moves, the ejector rod 31 may drive the rotating rod 30 to rotate. The ejector rod 31 may drive the rotating rod 30 to rotate, to enable the rotating rod 30 to drive the other end of the elastic arm 20 to detach from the terminal 11.

In some embodiments, as shown in FIG. 6b and FIG. 6e, one end of the rotating rod 30 has an arc-shaped surface, and the arc-shaped surface stops against the other end of the elastic arm 20. During driving, one end of the rotating rod 30 may slide relative to the other end of the elastic arm 20, so that the other end of the elastic arm 20 may be driven by the one end of the rotating rod 30.

Optionally, one end of the rotating rod 30 may be provided with a chute, the other end of the elastic arm 20 may be movably arranged in the chute, so that the one end of the rotating rod 30 may slide stably relative to the other end of the elastic arm 20 to avoid slippage.

Optionally, the other end of the elastic arm 20 is provided with a chute, and the chute extends along the length direction of the elastic arm 20. One end of the rotating rod 30 may be movably arranged in the chute, so that the one end of the rotating rod 30 may slide stably relative to the other end of the elastic arm 20 to avoid slippage.

In the embodiments of this application, as shown in FIG. 6e and FIG. 6g, a contact convex point 21 may be arranged in a region of the other end of the elastic arm 20 that stops against the terminal 11. There may be one or more contact convex points 21. The other end of the elastic arm 20 may come into stable contact with the terminal 11 through the contact convex point 21.

In an application process, the elastic arm 20 in the detection mechanism may be designed to be driven by the rotating rod 30 on a side of the rotating rod 30, and the card holder is directly driven in a direction in which the card tray is inserted. The terminal may be designed at a position opposite the other end of the elastic arm 20, and the terminal may be wrapped by plastic and expose a metal contact wall. In a case that the card tray is not inserted, the rotating rod 30 and the second elastic arm 202 of the elastic arm 20 may be in a detached state. The other end of the elastic arm 20 generates a pressing force on the terminal, and the contact convex point 21 at an end of the elastic arm may come into stable contact with the contact wall of the terminal. In a case that the card tray is inserted, the rotating rod 30 is pushed by the card tray to rotate. The rotating rod 30 drives the other end of the elastic arm 20. In a case that the card tray is inserted to the bottom, the other end of the elastic arm 20 can be completely driven away, so that the contact convex point is detached from the terminal, and a detection switch is switched on to implement the detection function.

Optionally, an insulation layer may be arranged between the seat body 10 and the terminal 11. The insulation layer may be a plastic layer. The insulation layer may prevent short-circuit between the terminal 11 and the seat body 10. The insulation layer may be an elastic layer, which has a buffering effect and can reduce damage to the terminal 11.

Optionally, the seat body 10 may be provided with an accommodating groove. The card tray is detachably arranged in the accommodating groove. The card tray further includes a limiting baffle 60. The limiting baffle 60 may be arranged on the edge of the frame edge of the supporting body 40, and at least part of the limiting baffle 60 is located outside the accommodating groove. In a case that the supporting body of the card tray is inserted into the accommodating groove, the supporting body may be limited by the limiting baffle 60 to facilitate removing the supporting body from the accommodating groove. In a case that the card tray is clamped on the seat body 10, for example, in a case that a supporting body of the card tray is inserted into the accommodating groove, the card tray can drive the ejection mechanism 13 to be in the second state.

During use, a state of the ejection mechanism 13 can be changed depending on a situation of the card tray on the seat body. The card tray may drive the ejection mechanism 13 to be in the second state. The ejection mechanism 13 may drive the other end of the elastic arm 20 to move, to enable the other end of the elastic arm 20 to stop against or detach from the terminal 11, so that the other end of the elastic arm 20 is electrically communicated with or disconnected from the terminal 11, to enable the detection mechanism to implement the detection function. During use, in a case that the card tray is inserted to enter a use state, the card tray may drive the ejection mechanism 13 to be in the second state, and the ejection mechanism 13 drives the other end of the elastic arm 20 to detach from the terminal 11, thereby implementing the detection function. A reaction force at the other end of the elastic arm 20 presses the ejection mechanism 13 tightly to prevent the ejection mechanism 13 from shaking and making noise. Since the reaction force does not act on the card tray, the holding force of the card tray can be prevented from being weakened, which prevents the card tray from falling out when the phone is dropped, and ensures the stability of the cooperation between the card tray and the card holder.

An embodiment of this application provides an electronic device, including the card tray assembly described in the foregoing embodiment. The electronic device having the card tray assembly in the foregoing embodiments has a small overall thickness during cooperation between the card holder and the card tray, which is conducive to the thinning and miniaturization design of the device and improving user experience. The embodiments of this application are described above with reference to the accompanying drawings, but this application is not limited to the foregoing specific embodiments, which are merely illustrative rather than limited. Under the inspiration of this application, a person of ordinary skill in the art may make various variations without departing from the scope of this application and the protection of the claims, and such variations shall fall within the protection of this application.
