Description
Technical field
The present invention relates to moving communicating field, in particular to possesses the mass transit card of distortion resistance.
Background technology
IC card refers to integrated circuit card, our general bus cards are exactly one kind of IC card, general common IC card
Communicated using the card reader of radio-frequency technique and IC card, IC card is distinguishing with magnetic card, and IC card is by integrated in card
Circuit stores information, and magnetic card is generally higher than magnetic card by the magnetic force record information in card, the cost of IC card, but confidentiality is more
It is good.Bus IC card is a kind of non-contact data card, it is to pass through the inductance coil on card by the chip being integrated in card
Effect (coil that inductance coil is namely coiled into by copper wire) makes sensing electric current at the both ends of coil by the effect of various circuits
It is changed into direct current, then a relatively large capacitance is incorporated to from direct current both ends, both end voltage can be made to keep stablizing, at coil both ends
Two lines are drawn again to chip, as signal transmssion line；When close to the POS, coil produces induced voltage, can to card and
The data of external data base are transmitted.
Most passengers are usually carried with when using bus IC card, and be placed in trouser pocket or wallet is made with facilitating
With；But since bus IC card is small and thickness is thin, song is easily lost or is bent over when carrying, and then cause
Chip in the fracture of bus IC card housing, card is damaged.
The content of the invention
It is an object of the invention to provide the mass transit card for possessing distortion resistance, the bend resistance energy of raising bus IC card
Power, prevents that chip is damaged in bus IC card.
The purpose of the present invention is achieved through the following technical solutions：
Possess the mass transit card of distortion resistance, including upper shell and lower housing shell, the upper shell and lower housing shell pass through rubber
Block is interconnected to constitute closed cavity, is installed with supporter in the cavity, chip is laid in supporter, and supporting
Filler is equipped between body and cavity, V-arrangement metal frame, the work of V-arrangement metal frame have been hingedly connected in supporter upper and lower ends
Gap is left between upper shell and lower housing shell respectively in moved end.Present invention work is that existing bus IC card shell is changed
Into upper shell, lower housing shell enclosed a cavity together with rubber block, supporter, supporter and upper lower casing are equipped with cavity
Filler is housed, bus chip is placed in supporter, the filler when IC card is impacted or is dropped from eminence between body
Certain buffer protection function can be played to chip, avoids chip from being damaged；When IC card be subject to it is vertical or angled with card face
External force and when will deform upon, deformation is produced with external force direction on upper shell and lower housing shell outer wall, positioned at supporter
On V-arrangement metal frame serve as keel bracket in filler, and two of V-arrangement metal frame between movable end and upper-lower casing also
Gap is left, so that the part between upper-lower casing can be bent in the range of certain angle, the two of V-arrangement metal frame at this time
Movable end is deformed upon around with the hinge joint on supporter along Impact direction, is distorted with slowing down external force caused by the entirety of card face,
Rubber block forced compression between upper shell and lower housing shell at the same time, so prevent IC card excessive distortion and cause chip by
Damage.
The shape of the rubber block is T-shaped, fluted in the end set of upper shell, is provided with the end of lower housing shell blind
Hole, the vertical end and engagement of rubber block, horizontal ends and the blind hole of rubber block coordinate.The rubber block of T-shaped by with upper and lower shell
The cooperation of groove and blind hole in body end portion, between upper-lower casing is ensured while closing sealing, ensure IC card by outer
Certain deformation quantity can occur for rubber block when power is impacted, to slow down the trend of IC card face distortion.
Two V-arrangement metal frames are symmetricly set on the top and bottom of supporter centered on cavity.Two V-arrangement gold
Belong to frame be symmetricly set on centered on cavity on supporter so that no matter IC card front or reverse side left end or right end
When being subject to external force, V-arrangement metal frame can make the deformation reaction of equidirectional, to reduce the degreeof tortuosity in card face, avoid being located at
Chip in supporter is damaged.
The filler is foamed plastics.Foamed plastics light weight, compactness is good, filled together with V-arrangement metal frame to
When in cavity, it can guarantee that while provide certain support for V-arrangement metal frame, moreover it is possible to V-shaped rest is freely deformed upon, is kept away
Exempt from it metal fatigue occurs and shortens service life.
Compared with prior art, the present invention have the following advantages and advantages：
1st, this hair is when IC card is subject to the external force vertical or angled with card face and will deform upon, upper shell and
Deformation is produced with external force direction on lower housing shell outer wall, the V-arrangement metal frame on supporter serves as keel in filler
Stent, and two of V-arrangement metal frame also leave gap between movable end and upper-lower casing, so that between upper-lower casing
Part can be bent in the range of certain angle, at this time the two of V-arrangement metal frame movable end around with supporter hinge joint along by
Force direction deforms upon, and is distorted with slowing down external force caused by the entirety of card face, while the rubber between upper shell and lower housing shell
Blob of viscose forced compression, external force is distorted dynamics caused by card face and is reduced to by the connecting portion of assistant spring in deformation process is replied
Minimum, and then prevent IC card excessive distortion and cause chip to be damaged；
2nd, two V-arrangement metal frames of the invention are symmetricly set on supporter centered on cavity so that no matter IC card
When front or reverse side left end or right end are subject to external force, V-arrangement metal frame can make the deformation reaction of equidirectional, with
Reduce the degreeof tortuosity in card face, avoid the chip in supporter from being damaged；
3rd, foamed plastics light weight of the invention, compactness is good, when being filled together with V-arrangement metal frame to cavity, energy
While ensureing to provide certain support for V-arrangement metal frame, moreover it is possible to V-shaped rest is freely deformed upon, avoids it that gold occurs
Belong to fatigue and shorten service life.
