Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The technical solutions disclosed by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1-FIG. 4, an embodiment of the present invention discloses a card tray, which can be installed in a terminal device, and cards such as a user identification card (ie a SIM card) and a memory card can be installed in the card tray , so that the card and the circuit board of the terminal device are electrically connected, thereby realizing the corresponding functions of the card. The card tray disclosed in the embodiment of the present invention specifically includes a card tray body 100 and a card suction cup 200 . The card tray body 100 has a first card slot 110 on the first side and a second card slot 120 on the second side. The shapes of the first card slot 110 and the second card slot 120 can be designed according to the structure of the card to be installed in the card tray. . The bottom surface of at least one of the first card slot 110 and the second card slot 120 is provided with a card suction cup 200, and the card suction cup 200 can apply a suction force to the card.

Specifically, the first side and the second side may be the same side of the card tray body 100, or they may be away from each other, so that cards can be placed on both sides of the card tray. Only one of the first card slot 110 and the second card slot 120 can be provided with the card suction cup 200. For example, during the process of installing the card in the card tray, the first card slot 110 faces upward, the second card slot 120 faces downward, and the card is placed in the card tray. After the first card slot 110, the card tray exerts a supporting force on the card. When the card is placed in the second card slot 120, the card tray cannot support the card. Therefore, a card suction cup 200 can be installed in the second card slot 120, so that the card The suction cup 200 absorbs the card to prevent the card from falling under the action of its own gravity, thereby facilitating the installation of the card on the card tray. In addition, although one side of the card tray is provided with the first card slot 110 and the other side is provided with the second card slot 120, the card can only be installed in the first card slot 110 or the second card slot 120, and the card can also be installed in the first card slot 110 or the second card slot 120 at the same time. Cards are installed in the card slot 110 and the second card slot 120 .

Of course, both the first card slot 110 and the second card slot 120 can be provided with card suction cups 200. At this time, no matter which side of the card tray is installed on the card tray, the card will not fall off, so there is no need to distinguish which side of the card tray is facing up. Which side is facing down, so the card can be installed in the tray more quickly.

In addition, in order to meet the waterproof requirements, the above-mentioned card tray may also include a waterproof sealing ring 300. The waterproof sealing ring 300 may be specifically configured as a silicone ring, which is disposed on the card tray body 100 and can be sealed with the casing of the terminal device. And then achieve the purpose of waterproofing.

According to the above content, the card suction cup 200 can absorb at least one card, so that the card is fixed on the card tray. Further, when the first side and the second side of the card tray body 100 are away from each other, cards can be placed on both sides of the card tray body 100, thereby meeting the requirement of double-sided card loading. A single card suction cup 200 can be applied to cards of various specifications, so the card tray can be installed with cards of various specifications, so that the compatibility of the card tray is better. In addition, when removing the card, the adsorption state between the card and the card suction cup 200 can be released only through a small gap, and the card suction cup 200 is not subjected to a large force during the process of removing the card, so the card suction cup 200 is not easy. damage, making the life of the card tray longer.

Only one card suction cup 200 can be set in the above-mentioned first card slot 110. When this structure is adopted, in order to ensure the reliability of adsorption, the size of the card suction cup 200 needs to be set larger, so as to increase the distance between the card and the card suction cup 200. Action area. However, if the size of the card suction cup 200 is too large, the suction force between the card suction cup 200 and the card is too large, which is not conducive to the removal of the card. Therefore, at least two card suction cups 200 can be disposed on the bottom surface of the first card slot 110, and the card suction cups 200 are arranged at intervals. The size of each card suction cup 200 can be set to be smaller, so that the suction force between the card and the card suction cup 200 is relatively moderate, and multiple card suction cups 200 and the card can form multiple connection points, thereby satisfying the adsorption reliability. Require.

Similarly, at least two card suction cups 200 may also be provided on the bottom surface of the second card slot 120 , and the card suction cups 200 are arranged at intervals. Of course, at least two card suction cups 200 may also be disposed on both the bottom surface of the first card slot 110 and the bottom surface of the second card slot 120 at the same time.

The bottom surface of the first card slot 110 may be set as a plane, and the card suction cup 200 is directly mounted on the plane. In another embodiment, an installation groove 130 may be formed on the bottom surface of the first card slot 110 , and the card suction cup 200 is fixedly connected to the installation groove 130 . After the installation slot 130 is provided, the protruding height of the card suction cup 200 relative to the bottom surface of the first card slot 110 is reduced, so that the space occupied by the card suction cup 200 is reduced, and the space occupied by the two after the card is installed on the card tray is reduced. Small, which is conducive to optimizing the lightness and thinness of the terminal device. Similarly, if the second card slot 120 is provided with a card suction cup 200 , a mounting slot 130 may also be formed on the bottom surface of the second card slot 120 .

Since the card suction cup 200 has a certain width, in order to accommodate more parts of the card suction cup 200 as much as possible, the installation groove 130 can be set wider, but as the width of the installation groove 130 increases, the structural strength of the card tray body 100 will also subsequently decreased. Therefore, in order to take into account the structural strength of the card tray body 100 and the lightness of the terminal device, the installation groove 130 can be set as a stepped groove, and the stepped groove includes a first groove 131 and a second groove formed on the bottom surface of the first groove 131 132 , the card suction cup 200 is fixedly connected with at least the second slot 132 . Since the width of the card suction cup 200 is gradually increased, the width of the first slot 131 is larger than that of the second slot 132, which not only can accommodate more parts of the card suction cup 200, but also prevents the installation slot 130 from being too large to affect Structural strength of the card tray body 100 .

In order to facilitate the installation of the card suction cup 200 , the card suction cup 200 may be adhered to the card tray body 100 by means of adhesive. Specifically, it can be realized by a dispensing process or double-sided adhesive bonding. Considering that the bonding reliability of the glue dispensing process is higher, in the embodiment of the present invention, the card suction cup 200 is preferably bonded to the card tray body 100 through the glue dispensing process. At this time, the second groove 132 can be a glue dispensing groove, and the first groove 131 can be a glue overflow groove. During the dispensing operation, the glue in the second groove 132 can overflow to the first groove 131, thereby preventing the excess glue from directly overflowing to other positions and affecting the appearance and texture of the tray.

In one embodiment, as shown in FIG. 1 to FIG. 4 , the card suction cup 200 may include a connected mounting portion 210 and a suction portion 220 . That is, the adsorption part 220 is arranged around the periphery of the installation part 210 with the installation part 210 as the center. In a specific embodiment, the adsorption part 220 may be a circular structure. The structure of the card suction cup 200 is relatively simple, and it is easier to process. It should be noted that the contact area between the adsorption portion 220 and the card is relatively large, so its main function is to adsorb the card. The mounting portion 210 can also contact the card to adsorb the card, but its main function is to realize the connection between the card suction cup 200 and the card tray. Connections between bodies 100 .

In another embodiment, as shown in FIGS. 5-8 , the card suction cup 200 includes a first ring piece 230 , an annular mounting portion 240 and a second ring piece 250 , and the first ring piece 230 and the second ring piece are connected in sequence 250 are respectively disposed on the inner side and the outer side of the annular mounting portion 240 . At this time, the entire card suction cup 200 is an annular structure, and its contact position with the card can be appropriately expanded, so that the stability of the card relative to the card tray is higher, and at the same time, the contact area between the card suction cup 200 and the card will not be too large. Large and inconvenient to remove the card.

Further, the first ring piece 230 , the annular mounting portion 240 and the second ring piece 250 are all square annular structures. Generally, the card has a generally square structure. Therefore, the card suction cup 200 can be better matched with the card structure by setting the card suction cup 200 as a square ring structure, so that the suction force between the card suction cup 200 and the card can be evenly distributed on the card, so that the The card is more stable after being installed on the card tray.

In order to increase the adsorption force, the card suction cup 200 can be set as a silicone suction cup. The elasticity of the silicone suction cup is better, and it will deform greatly after being stressed. The suction force between the card suction cups 200 is greater, and the reliability of the connection between the two is higher. In addition, the silicone suction cup is not easy to fail after long-term use, which further prolongs the service life of the card tray.

Based on the above structure, an embodiment of the present invention further discloses a terminal device, which includes a casing and a card tray disclosed in any of the above embodiments, and the card tray is mounted on the casing.

The terminal device disclosed in the embodiment of the present invention may be a smart phone, a tablet computer, an e-book reader, or a wearable device. Certainly, the terminal device may also be other devices, which are not limited in this embodiment of the present invention.

The above embodiments of the present invention mainly describe the differences between the various embodiments. As long as the different optimization features of the various embodiments are not contradictory, they can be combined to form better embodiments. No longer.

The above are only embodiments of the present invention, and are not intended to limit the present invention.
