[0024] The utility model provides a card slot structure that can automatically adapt to a card, comprising a card slot accommodating portion, a card slot and an adjusting portion, wherein the card slot is arranged inside the card slot accommodating portion, and the adjusting portion can be movably connected between the card slot accommodating portion and the card slot, and the adjusting portion makes the card slot and the card slot accommodating portion in a fitted state and can move vertically up and down. The adjusting portion can automatically adjust the accommodating space of the card slot accommodating portion and the card slot according to the thickness of the card, so as to realize automatic adaptation to cards of different thicknesses, expand the use scope of electronic devices applying the card slot structure of the present application, reduce the cost of replacing parts of electronic devices, and improve the user experience.

[0025] The card slot accommodating portion includes a limiting portion and a guiding portion, the limiting portion includes an upper limiting plate 1 and a lower limiting plate 4, the card slot includes an upper shell 2 and a lower shell 3, and the upper limiting plate 1, the upper shell 2, the lower shell 3 and the lower limiting plate 4 are arranged from top to bottom. The space enclosed by the upper limiting plate 1 and the lower limiting plate 4 is used to accommodate the card slot, which plays a protective role on the card slot, and the card slot accommodating portion is not fixedly connected to the card slot, and the card slot accommodating portion provides a buffer space for the movement of the card slot.

[0026] In order to prevent the card from causing the card slot to move when the card is inserted, in the present application, first limiting ribs 101 extending downward are provided on both sides of the upper limiting plate 1, and second limiting ribs 401 extending upward are provided on both sides of the lower limiting plate 4. The first limiting rib 101 abuts against the outer side of the card slot, the second limiting rib 401 abuts against the outer side of the first limiting rib 101, and a third limiting rib 404 is provided on the rear side of the lower limiting plate 4.

[0027] The first limiting rib 101, the second limiting rib 401 and the third limiting rib 404 form limiting protection on the side and back of the card slot to prevent the card slot from moving when the card is inserted, so that the chip of the card cannot effectively contact the card slot, and the card cannot be recognized and used.

[0028] In order to achieve the automatic adaptation of the internal space of the card slot to different cards, the adjustment part in the present application includes a pin 5, a spring 6 and a retaining spring 7. The free end of the pin 5 passes through the upper limit plate 1, the card slot and the lower limit plate 4 in sequence. Correspondingly, the upper limit plate 1, the card slot and the lower limit plate 4 are provided with a through hole corresponding to the pin 5.

[0029] In this embodiment, a cap is provided at the upper end of the pin 5, and an annular groove 501 is provided at the lower end. The spring 6 is sleeved on the pin 5 above the upper limit plate 1, and the retaining spring 7 is clamped in the groove 501 of the pin 5 below the lower limit plate 4. By sleeved on the spring 6 on the pin 5, a longitudinal movement space is provided for the upper limit plate 1, the upper shell 2, the lower shell 3 and the lower limit plate 4, that is, when no card is inserted into the card slot, the spring 6 stretches to make the upper shell 2 and the lower shell 3 in abutment state. When the card is inserted into the card slot, the upper and lower sides of the card contact with the upper shell 2 and the lower shell 3 and squeeze the upper shell 2 and the lower shell 3 to expand upward and downward respectively. The spring 6 shrinks to different degrees according to the thickness of the card, so that the chip contacts on the card always keep in a fitting state with the upper shell 2, which is convenient for identifying and using the card. The cap, the groove 501 and the retaining spring 7 on the pin 5 limit the movement range of the entire card slot.

[0030] A spring pin 202 is provided inside the upper shell 2 of the card slot, and a circuit board 201 is provided on the outer side of the upper shell 2 at a position corresponding to the spring pin 202. One side of the spring pin 202 contacts the chip of the card, and the other side is connected to the circuit board 201, thereby identifying the information of the card and transmitting the information to the main module of the electronic device through the circuit board 201, so that the user can use the card to perform the corresponding communication needs.

[0031] The guide portion includes a first guide plate and a second guide plate 402 which are respectively arranged at the front ends of the upper limit plate 1 and the lower limit plate 4. The first guide plate includes a front guide plate 102 and a side guide plate 103. The front end of the front guide plate 102 is provided with an upward arc portion. The side guide plates 103 are located on both sides of the front guide plate 102, and their front ends are respectively provided with outward arc portions.

[0032] In this embodiment, the horizontal height of the first guide plate is lower than the upper limit plate 1, and the horizontal height of the second guide plate 402 is higher than the lower limit plate 4. On the one hand, the height difference forms a limit for the front side of the card slot, and on the other hand, the height space of the first guide plate and the second guide plate 402 is reduced to match the internal height of the card slot, which is useful for card insertion guidance. Through the front guide plate 102, the side guide plate 103 and the second guide plate 402, a guide for card insertion is formed at the entrance of the card slot. The arcs of different angles set thereon form a larger card insertion range. When inserting a card, the user does not need to accurately align the entrance of the card slot, and can smoothly insert the card according to the arc direction. At the same time, the arc of the front guide plate 102 and the second guide plate 402 extending to the outside of the card slot can also protect the card slot, preventing rainwater, dust and other debris from entering the card slot and affecting the use of the card slot.

[0033] The card slot accommodating portion further includes a connecting portion 403 , which is vertically fixed on both sides of the lower limiting plate 4 , and is provided with a through hole for connection.

[0034] In this embodiment, the height of the second limiting rib 401 is greater than that of the first limiting rib 101, and the connection portion 403 is used to provide a connection between the slot structure and other components. The connection portion 403 is arranged on the lower limiting plate 4, so that the overall slot structure is connected to other components through the lower limiting plate 4 located on the outermost side of the structure, forming a fixed connection on the outside and a movement space on the inside, and the connection is made more convenient and stable by the vertically arranged connecting arm.

[0035] The card slot receiving portion is made of a heat-conducting metal material, and heat dissipation windows 8 are provided on the upper and lower sides of the card slot receiving portion.

[0036] In this embodiment, the card slot structure is used in electronic devices, such as card-inserting telephones. Since electronic devices generate heat during use, timely heat dissipation has a key impact on improving the safety and service life of electronic devices. Therefore, the present application improves the heat dissipation effect by using a card slot accommodating portion made of a heat-conductive metal material and providing heat dissipation windows on the upper and lower sides of the card slot accommodating portion. This structure not only has a heat dissipation effect on the card slot, but also can help the electronic device to effectively dissipate heat when applied to electronic devices, thereby improving the safety and service life of the equipment.
