[0007] An auxiliary heat dissipation structure is provided on the bottom plate. The auxiliary heat dissipation structure includes a plurality of longitudinal diversion grooves provided on the bottom plate and communicating with the card slot. The ends of the longitudinal diversion grooves are commonly connected to a transverse diversion groove, and one end of the transverse diversion groove communicates with the through groove.

[0008] Further, the gasket is annular and made of silica gel material.

[0009] Further, the card slot is larger than the card body.

[0010] Further, a limiting groove is communicated and arranged at the lower end of the card slot; the lower end of the card body can be inserted into the limiting groove.

[0011] Further, a plurality of second longitudinal diversion grooves are communicated and arranged between the through groove and the card slot.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Example 1, in combination with the attached Figure 1 、 3, a mobile phone case with a built-in NFC unlocking chip, including a bottom plate 1 and a surrounding edge 2. There is a through groove 3 at one corner of the bottom plate 1. The through groove 3 is used to place components such as a camera, and is also used to connect the longitudinal diversion groove 11 and the second longitudinal diversion groove 12 for heat dissipation. Along the circumference on the upper surface of the bottom plate 1, there is a gasket 4. The gasket 4 is annular and made of silica gel. It is used to separate and buffer the mobile phone so that the mobile phone does not closely adhere to the bottom plate 1, avoiding the situation of unable to dissipate heat and damaging the mobile phone. The surrounding edge 2 is integrally formed, and all four corners are arc-shaped, making it comfortable to hold.

[0024] Combined with the attached Figure 1 , 2 , 3, there is a card body 5 on the bottom plate 1; there is a storage structure between the card body 5 and the bottom plate 1. The storage structure includes a card slot 7 provided on the bottom plate 1. The card slot 7 is larger than the card body 5, facilitating the insertion of the card body 5 and also leaving some gaps between the card body 5 and the card slot 7 for heat dissipation. On the bottom plate 1 and on both sides of the card slot 7, there are convex strips 9. There are multiple convex strips 9, and their height is the same as that of the gasket 4, jointly supporting the mobile phone body so that it does not directly adhere to the bottom plate 1. There is a shielding sticker 6 on the card body 5. The shielding sticker 6 is an anti-interference and anti-magnetic sticker, which is a common sticker in the prior art and can avoid signal interference or demagnetization between the card body 5 and the mobile phone during long-term use.

[0025] Combined with the attached drawing, a limiting groove 8 is connected and provided at the lower end of the card slot 7; the lower end of the card body 5 can be inserted into the limiting groove 8 to limit the card body 5, so that the card body 5 will not directly fall off when the mobile phone case is removed later.

[0026] Combined with the attached drawing, an auxiliary heat dissipation structure is provided on the bottom plate 1. The auxiliary heat dissipation structure includes a plurality of longitudinal diversion grooves 10 provided on the bottom plate 1 and connected to the card slot 7. The ends of the longitudinal diversion grooves 10 are jointly connected to a transverse diversion groove 11. One end of the transverse diversion groove 11 is connected to the through groove 3; several second longitudinal diversion grooves 12 are connected between the through groove 3 and the card slot 7. Through the multiple longitudinal diversion grooves 10, transverse diversion groove 11, and second longitudinal diversion grooves 12, a path can be formed to divert and dissipate the heat generated by the mobile phone, avoiding the card body 5 from affecting heat dissipation.

[0027] Working principle of the present utility model: A shielding sticker 6 is pasted on the card body 5. The shielding sticker 6 is an anti-interference and anti-magnetic sticker, which is a common sticker in the prior art and can avoid signal interference or demagnetization between the card body 5 and the mobile phone during long-term use. Then, the card body 5 is placed into the card slot 7 and then inserted downward into the limit slot 8, so that the card body 5 will not directly fall off when the mobile phone case is removed later, which is convenient for use. When unlocking, the mobile phone case is brought close to the vehicle B-pillar or other positions for swiping NFC, and the unlocking can be achieved. In addition, due to the setting of the washer 4 and the rib 9, the mobile phone will not directly press against the card body 5 and the bottom plate 1, and there are gaps. The heat generated by the mobile phone during use will exchange air in these gaps, achieving the purpose of heat dissipation, and it is more dust-proof than the directly penetrating heat dissipation hole structure.

[0028] The present utility model and its implementation manners have been described above. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the creative concept of the present utility model, they shall fall within the protection scope of the present utility model.
