Problems solved by technology

[0003] When most passengers use bus IC cards, they usually carry them with them and put them in their trouser pockets or wallets for easy use; however, due to their small size and thin thickness, bus IC cards are easy to lose or be bent when carrying them. , which in turn causes the bus IC card shell to break and the chip in the card to be damaged

Embodiment 1

[0020] Such as figure 1 As shown, this embodiment includes an upper casing 1 and a lower casing 2, the upper casing and the lower casing 2 are connected to each other through rubber blocks 4 to form a closed cavity, and a support body 6 is fixedly installed in the cavity to support A chip 3 is placed in the body 6, and a filler 5 is provided between the support body 6 and the cavity, and a V-shaped metal frame 7 is hingedly connected to the upper and lower ends of the support body 6 respectively, and the movable ends of the V-shaped metal frame 7 are respectively There is a gap between the upper case 1 and the lower case 2 . The work of the present invention is an improvement to the existing bus IC card shell, and the upper casing 1, the lower casing 2 and the rubber block 4 are enclosed into a cavity, and a support body 6 is arranged in the cavity, and the support body 6 is connected with the upper and lower There is a filler 5 between the housings 2, and the bus chip 3 is p...

Embodiment 2

[0023] Such as figure 1 As shown, in this embodiment, on the basis of Embodiment 1, the two V-shaped metal frames 7 are symmetrically arranged on the top surface and the bottom surface of the support body 6 with the cavity as the center. Two V-shaped metal frames 7 are symmetrically arranged on the support body 6 with the cavity as the center, so that when the front or back of the IC card or the left end or the right end is subjected to external force, the V-shaped metal frame 7 can make the same direction. Deformation reaction to reduce the degree of distortion of the card surface and avoid damage to the chip 3 in the support body 6 .

[0024] Preferably, the filler 5 is foamed plastic. The foamed plastic is light in weight and has good tightness. When it is filled into the cavity together with the V-shaped metal frame 7, it can ensure that the V-shaped metal frame 7 is provided with a certain support, and at the same time, it can also make the V-shaped bracket deform freely...

Abstract

The invention discloses a self-adjusting anti-twist bus card which comprises an upper shell and a lower shell. The upper shell and the lower shell are connected through a rubber block to form a sealed cavity, a supporting body is fixedly arranged in the cavity, a chip is arranged in the supporting body, filling is arranged between the supporting body and the cavity, V-shaped metal frames are connected to the upper end and the lower end of the supporting body in a hinged mode, and gaps are reserved between the moving end of the corresponding V-shaped metal frame and the upper shell and between the moving end of the corresponding V-shaped metal frame and the lower shell. The V-shaped metal frames located on the supporting body serve as the keel supports in the filling, the gaps are reserved between the moving end of the corresponding V-shaped metal frame and the upper shell and between the moving end of the corresponding V-shaped metal frame and the lower shell, the part between the upper shell and the lower shell can be bent in a certain angle range accordingly, the two moving ends of the V-shaped metal frames are deformed around the hinge points between the metal frames and the supporting body in the stress direction so as to lower distortion, caused by external force, on the whole card face, and thus the damage, caused by excessive distortion of the IC card, to the chip is further prevented.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a self-adjusting anti-distortion bus card. Background technique [0002] IC card refers to integrated circuit card. The bus card we generally use is a kind of IC card. Generally, common IC cards use radio frequency technology to communicate with IC card readers. There is a difference between IC cards and magnetic cards. The card stores information through the integrated circuit in the card, while the magnetic card records information through the magnetic force in the card. The cost of the IC card is generally higher than that of the magnetic card, but the confidentiality is better. The bus IC card is a non-contact data card, it is through the chip integrated in the card through the inductance coil on the card (the inductance coil is also a coil made of copper wire) at both ends of the coil through various The function of the circuit makes the induced current become DC, and th...
