Technical Field

[0001] The present invention relates to the technical field of smart cards, and more particularly to a smart card housing structure with an IC chip. Background Art

[0002] A standard contactless smart card is structurally composed of a plastic card substrate, a resonant coil, and a smart card chip. Among them, the smart card chip is most commonly an encapsulated IC chip. The shape of a standard smart card is a rectangular thin sheet with dimensions of 85.5 mm × 54 mm × 0.76 mm. In recent years, contactless smart cards of different shapes have gradually emerged, such as various geometric shape cards, pendant cards, bracelet-shaped cards, etc., which are generally collectively referred to as "special-shaped cards". Special-shaped cards have been widely used in many fields and industries, such as commercial retail, transportation, healthcare, culture and entertainment, restaurants and hotels, etc.

The smart card includes a card body made of a rigid material, and an installation groove is formed on the card body; a chip assembly is installed in the installation groove. The chip assembly includes an insulating sheet body, a chip groove is provided on the insulating sheet body, the IC chip is encapsulated in the chip groove, and the outer surface of the insulating sheet body is adjacent to the inner wall of the installation groove. The method includes manufacturing the chip assembly, encapsulating the IC chip on the insulating sheet body. A chip groove with an open upper end is provided on the insulating sheet body, and the IC chip is encapsulated in the chip groove; an installation groove is provided on the card body made of a rigid material, the chip assembly is fixed in the installation groove, the outer surface of the insulating sheet body is adjacent to the inner wall of the installation groove, and after the chip assembly is encapsulated into the installation groove, a plurality of electrical contacts of the IC chip are exposed on the surface of the card body.

[0004] In the prior art including the above patents, the IC chip is encapsulated in the chip groove of the card body for use. For a conventional standard smart card, the card body is a rectangular plastic or PVC thin sheet. In the field of smart cards for children, the rectangular plastic or PVC thin sheet is easily bent, resulting in damage to the chip due to bending. Moreover, the card surface of the plastic or PVC thin sheet smart card is often made by screen printing, so that the pattern on the card surface cannot be replaced, making the thin sheet smart card less suitable for children.

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0036] like Figure 1-13 As shown, a smart card housing structure with an IC chip includes a chip 41 and a coil 42 symmetrically connected thereto, and also includes:

[0037] An installation component, which includes an upper board seat 11 and a lower board seat 12. The upper board seat 11 and the lower board seat 12 are parallel and joined together to form an installation cavity 3 for installing a chip 41 and a coil 42 inside. And placement grooves 92 for fixing the card surface are provided on both the upper board seat 11 and the lower board seat 12.

[0038] A fixing component, which includes a front end seat 21, side blocking strips 22 and a rear end seat 23. The rear end seat 23, the side blocking strips 22 and the front end seat 21 are sequentially inserted and hooped around the peripheries of the upper board seat 11 and the lower board seat 12 to form a smart card housing.

[0039] Specifically, it also includes fixing bolts 24. As Figure 9 shown, a number of limit holes 94 are provided on the peripheries of both the upper board seat 11 and the lower board seat 12, and a number of limit posts 95 are provided on the front end seat 21, the side blocking strips 22 and the rear end seat 23. An extending plate 231 is provided on the rear end seat 23, a resisting groove 221 and an insertion groove 222 are provided on the side blocking strip 22, and an insertion portion 212 is provided on the front end seat 21. First, the upper board seat 11 and the lower board seat 12 can be joined together to install the chip 41 and the coil 42 into the installation cavity 3. Then, the rear end seat 23 is first inserted through the limit posts 95 around the rear end peripheries of the upper board seat 11 and the lower board seat 12. Subsequently, the side blocking strips 22 are respectively inserted through the limit posts 95 around the two side peripheries of the upper board seat 11 and the lower board seat 12. At this time, the resisting groove 221 of the side blocking strip 22 presses the extending plate 231 tightly. Then, the front end seat 21 is inserted through the limit posts 95 around the front end peripheries of the upper board seat 11 and the lower board seat 12, so that the insertion portion 212 is inserted into the insertion groove 222 of the side blocking strip 22, completing the circumferential hoop splicing of the rear end seat 23, the side blocking strips 22 and the front end seat 21 on the peripheries of the upper board seat 11 and the lower board seat 12. Finally, the fixing bolts 24 pass through the front end seat 21 and the side blocking strip 22 and are threadedly connected to the rear end seat 23 to complete the overall locking and fixing. At this time, the upper board seat 11, the lower board seat 12, the front end seat 21, the side blocking strips 22 and the rear end seat 23 are overall spliced to form a smart card housing.

[0040] The upper board seat 11 and the lower board seat 12 are joined together in parallel to install the chip 41 and the coil 42 to increase the housing thickness of the smart card housing structure. And the existence of the rear end seat 23, the side blocking strips 22 and the front end seat 21 can also improve the overall bending resistance of the smart card housing, thereby improving the protection of the chip 41 and the coil 42 installed inside the smart card housing structure, and improving the applicability of the smart card housing for children's use.

[0041] It also includes a transparent cover plate 91 disposed on the surface of the placement groove 92. When the smart card housing structure is installed, the front seat 21 can be removed by loosening the fixing bolts 24, thereby exposing the placement groove 92 of the upper plate seat 11 and the lower plate seat 12. Different required card faces can be inserted and fixed in the placement groove 92 to complete the replacement of the card face of the smart card housing. Subsequently, the front seat 21 is fixedly locked with the upper plate seat 11 and the lower plate seat 12 again through the fixing bolts 24 to complete the re-assembly of the smart card housing. The transparent cover plate 91 can be used to observe and protect the card face in the placement groove 92. Furthermore, the placement groove 92 of the upper plate seat 11 and the lower plate seat 12, as well as the detachable front seat 21, side blocking strips 22, and rear seat 23, are used to realize the replacement of the card face of the smart card housing, improve children's love for the smart card to reduce the probability of the smart card being bent, and further improve the applicability of the smart card housing for children.

[0042] In the above solution, the upper plate seat 11 and the lower plate seat 12 are assembled in parallel to install the chip 41 and the coil 42 to increase the housing thickness of the smart card housing structure. The presence of the rear seat 23, side blocking strips 22, and front seat 21 can also improve the overall bending resistance of the smart card housing, thereby improving the protection of the chip 41 and the coil 42 installed inside the smart card housing structure. Moreover, the placement groove 92 of the upper plate seat 11 and the lower plate seat 12, as well as the detachable front seat 21, side blocking strips 22, and rear seat 23, are used to realize the replacement of the card face of the smart card housing, improve children's love for the smart card to reduce the probability of the smart card being bent, and further improve the applicability of the smart card housing for children.

[0043] As another embodiment provided by the present invention, it also includes flexible clamping plates 5 symmetrically arranged in the installation cavity 3. The two ends of the flexible clamping plates 5 are respectively fixedly connected in the installation cavity 3 so that the hard bearing plate 51 arranged in the middle of the flexible clamping plates 5 clamps the chip 41, and the flexible clamping plates 5 clamp the coil 42.

[0044] Specifically, as Figure 2As shown in the figure, two flexible clamping plates 5 are arranged in the installation cavity 3 parallel to the upper plate seat 11 and the lower plate seat 12, and the longitudinal ends of the flexible clamping plates 5 are fixed in the installation cavity 3. Thus, the two flexible clamping plates 5 clamp the vertical sides of the coil 42, and the rigid bearing plates 51 of the flexible clamping plates 5 clamp the vertical sides of the chip 41. The flexible clamping plates 5 and the rigid bearing plates 51 are used to complete the suspended clamping and fixing of the chip 41 and the coil 42 in the installation cavity 3, thereby avoiding the problem of torsional damage to the chip 41 or the coil 42 when the smart card housing is slightly bent by external force, and improving the installation protection of the chip 41 and the coil 42. The rigid bearing plate 51 is used to clamp and fix the chip 41, and the rigid bearing plate 51 is tightened by the flexible clamping plate 5 to be suspended in the installation cavity 3. Thus, while the rigid bearing plate 51 can clamp and fix the chip 41, it can further prevent the chip 41 from being bent by external force, and can also avoid the damage problem of the chip 41 caused by the chip 41 hitting the upper plate seat 11 and the lower plate seat 12, further improving the protection of the chip 41.

[0045] Further, through holes 52 are provided at the longitudinal ends of the flexible clamping plates 5. A supporting portion 121 and a through column 122 are provided on the lower plate seat 12. The upper plate seat 11 and the lower plate seat 12 are joined together so that the through column 122 passes through the through hole 52, and the supporting portion 121 and the upper plate seat 11 clamp the longitudinal ends of the two flexible clamping plates 5. As Figure 10 shown, the direction of the parallel long sides of the flexible clamping plate 5 is the longitudinal direction, and the direction of the parallel short sides is the transverse direction. As Figure 8 shown, when the upper plate seat 11 and the lower plate seat 12 are joined together, the flexible clamping plates 5, the rigid bearing plates 51, the chip 41 and the coil 42 are all located in the installation cavity 3, and the through column 122 of the lower plate seat 12 passes through the through holes 52 of the two flexible clamping plates 5 at the same time to realize the fixed limit of the two ends of the flexible clamping plates 5, and the supporting portion 121 of the lower plate seat 12 and the upper plate seat 11 clamp and fix the two ends of the flexible clamping plate 5 as the short sides, thereby further improving the fixing stability of the two ends of the flexible clamping plates 5.

[0046] Moreover, since the rigid bearing plate 51 provided on the flexible clamping plate 5 is used to clamp and fix the chip 41, the flexible clamping plate 5 can deform and contract or stretch to realize the buffering during the movement of the chip 41, further improving the protection of the chip 41.

[0047] As another embodiment provided by the present invention, a predetermined gap is provided between the flexible clamping plate 5 and the side wall of the installation cavity 3, and the side surface of the rigid bearing plate 51 facing the inner wall of the installation cavity 3 is a convex arc abutting surface 511.

[0048] Specifically, as Figure 3As shown, the direction parallel to the flexible splint 5 is horizontal at this time, and the direction perpendicular to the flexible splint 5 is vertical. There is a predetermined distance between the flexible splint 5 and the vertical side wall of the installation cavity 3 so that there is a predetermined distance between the flexible splint 5 and the upper plate seat 11 or the lower plate seat 12 respectively. When the flexible splint 5 deforms under external inertia or impact, the possibility of the flexible splint 5 or the hard bearing plate 51 hitting the upper plate seat 11 or the lower plate seat 12 is reduced, thereby further realizing the protection and buffering of the chip 41 and the coil 42 and improving the service life of the chip 41. The predetermined distance between the flexible splint 5 and the upper plate seat 11 or the lower plate seat 12 is 2-3 mm.

[0049] Secondly, as Figure 10 shown, a convex arc contact surface 511 is provided on the hard bearing plate 51, and as Figure 3 shown, the convex arc contact surface 511 is located on the side of the hard bearing plate 51 facing away from the chip 41. When the flexible splint 5 deforms under external inertia or impact, if the surface of the convex arc contact surface 511 of the hard bearing plate 51 moves and hits the upper plate seat 11 or the lower plate seat 12, the presence of the convex arc contact surface 511 can improve the compressive and bending strength of the hard bearing plate 51, thereby further improving the protection of the hard bearing plate 51 for the chip 41.

[0050] When the smart card housing is bent due to improper use, as Figure 2 shown, the cross-section of the smart card housing is still rectangular. The shape of the smart card housing makes it easier for the smart card housing to be bent laterally to form a crease substantially perpendicular to the side baffle 22. The presence of the coils 42 symmetrically arranged on both sides of the chip 41 enables the coils 42 on the other side to still be used normally to drive the chip 41 even if one side of the coils 42 is damaged by bending. The upper plate seat 11 and the lower plate seat 12 are bent under drive to deform the inside of the installation cavity 3, that is, one of the upper plate seat 11 or the lower plate seat 12 bends and extends into the installation cavity 3. At this time, the apex of the upper plate seat 11 or the lower plate seat 12 bending and extending into the installation cavity 3 will press on the convex arc contact surface 511 of the hard bearing plate 51, and then the bent upper plate seat 11 or the lower plate seat 12 presses the hard bearing plate 51 to push the hard bearing plate 51 and the chip 41 to move away from the bending point. At the same time, the flexible splint 5 also adaptively deforms and contracts or stretches to cooperate with the movement of the hard bearing plate 51 and the chip 41 in the installation cavity 3, realizing that when the smart card housing is bent, the chip 41 can move adaptively in the installation cavity 3 to leave the bending position, further improving the protection of the chip 41.

[0051] As another embodiment provided by the present invention, it further includes an insulating film 6, which is symmetrically arranged in the installation cavity 3 to separate the chip 41 and the coil 42 from the hard bearing plate 51 and the flexible splint 5.

[0052] Specifically, as Figure 3As shown, an insulating film 6 is disposed between the flexible splint 5 and the chip 41. At this time, the insulating film 6 is used to separate the chip 41 from the rigid bearing plate 51, and the coil 42 is separated from the flexible splint 5, thereby realizing further insulation protection for the chip 41 and the coil 42. The insulating film 6 is a smooth flexible film made of insulating material. Secondly, when the smart card housing is bent, since the rigid bearing plate 51 will be squeezed by the housing and move and change its position within the installation cavity 3, and the flexible splint 5 will follow the rigid bearing plate 51 to undergo adaptive deformation. The insulating film 6 is used to separate the flexible splint 5 from the coil 42, thus avoiding the problem that the coil 42 is wrinkled or stretched and broken due to friction during the process of the flexible splint 5 deforming and shrinking or stretching, thereby further improving the protection of the coil 42, ensuring that the coil 42 and the chip 41 can still be used normally after the smart card housing is bent, improving the use stability and applicability of the smart card, and facilitating the use by children.

[0053] And when the smart card housing is bent, since the smart card housing has an upper plate seat 11 and a lower plate seat 12, both the upper plate seat 11 and the lower plate seat 12 are pressed and bent in one direction and damaged, that is, among the upper plate seat 11 and the lower plate seat 12, one plate seat is concave and the other plate seat is convex. At this time, the convex plate seat can be directly pressed to return to a horizontal state, and the concave plate seat is not manually reset and still remains concave, thereby avoiding the problem that the plate seat is repeatedly bent and causes accelerated fracture. And the plate seat reset to the horizontal state is convenient for the actual use and placement of the smart card housing, further improving the durability of the smart card housing, and can be manually adjusted to continue to be used after being bent. And the concave portion of the concave plate seat can squeeze the rigid bearing plate 51 and the chip 41 away from the bent portion of the smart housing, and make the chip 41 and the rigid bearing plate 51 still remain at a position away from the bent portion within the installation cavity 3, so as to avoid possible secondary bending of the housing from causing damage to the chip 41, and further improving the protection of the chip 41.

[0054] As another embodiment provided by the present invention, limiting portions 61 extending and abutting against both sides of the flexible splint 5 are symmetrically connected to both sides of the insulating film 6 to laterally limit the insulating film 6.

[0055] Specifically, as Figure 10 shown, limiting portions 61 are provided at both ends of the long side of the insulating film 6 extending to the flexible splint 5. As Figure 6 shown, the limiting portions 61 extend and abut against the slope portions 53 on the long side of the flexible splint 5, thereby limiting and fixing the insulating film 6 in the short side direction of the flexible splint 5, thus avoiding the problem that the insulating film 6 moves laterally and separates from between the chip 41 and the rigid bearing plate 51, resulting in direct contact between the chip 41 and the rigid bearing plate 51, and improving the insulation protection stability of the insulating film 6 for the chip 41. And the limiting portions 61 abut against the slope portions 53 to improve the stability of the lateral limiting arrangement of the insulating film 6.

[0056] As another embodiment provided by the present invention, flexible embedding strips 211 are symmetrically arranged on the front end seat 21, and through slots 93 that are spliced with each other are formed on the upper plate seat 11 and the lower plate seat 12. The flexible embedding strips 211 move along the through slots 93 and extend into the installation cavity 3 to form a high-pressure environment in the installation cavity 3.

[0057] Specifically, as Figure 9 shown, when the upper plate seat 11 and the lower plate seat 12 are spliced with each other to form the installation cavity 3 for installing the chip 41 and the coil 42, the through slots 93 on the upper plate seat 11 and the lower plate seat 12 are also spliced with each other. Subsequently, the rear end seat 23, the side blocking strips 22 and the front end seat 21 can be sequentially spliced to form the smart card housing structure. When the front end seat 21 is installed on the upper plate seat 11 and the lower plate seat 12, the flexible embedding strips 211 extend into the through slots 93 and gradually move into the installation cavity 3. While the flexible embedding strips 211 enter the installation cavity 3, they also abut against and seal the contact gap between the upper plate seat 11 and the lower plate seat 12 in the installation cavity 3, thereby improving the sealing performance of the installation cavity 3 and preventing external moisture or dust from invading the installation cavity 3 and causing damage to the chip 41 or the coil 42, and further improving the protection of the chip 41 or the coil 42. Secondly, when the flexible embedding strips 211 gradually move into the installation cavity 3, the volume in the installation cavity 3 is also reduced, thereby increasing the air pressure in the installation cavity 3 to form a high-pressure environment, further preventing external moisture or dust from invading the installation cavity 3.

[0058] As still another embodiment provided by the present invention, the limiting portion 61 is curled into a spiral shape, the flexible embedding strip 211 extends into the installation cavity 3 to wrap the limiting portion 61, and the upper plate seat 11 and the lower plate seat 12 are driven to bend so that the flexible embedding strip 211 squeezes the limiting portion 61, and the limiting portion 61 is first deformed under pressure into an elliptical shape to relax the insulating film 6, and then the limiting portion 61 continues to be deformed under pressure into a plate shape to tighten the insulating film 6.

[0059] Specifically, as Figure 6 shown, the limiting portions 61 connected to both ends of the insulating film 6 are film rolls curled into a spiral shape. When the upper plate seat 11, the lower plate seat 12, the rear end seat 23, the side blocking strips 22 and the front end seat 21 are spliced to form the smart card housing structure, the flexible clamping plates 5, the insulating film 6, the chip 41 and the coil 42 are clamped and fixed in the installation cavity 3. A wrapping groove 213 is formed on the flexible embedding strip 211, and the limiting portions 61 on the two insulating films 6 are both wrapped in the wrapping groove 213 of the flexible embedding strip 211. When the smart card housing is bent, first, the smart card housing is slightly bent, so that the flexible embedding strip 211 at the bent portion is also slightly bent and squeezes the limiting portion 61, that is, as Figure 13As shown in the upper side view in [reference], the originally circularly curled limiting part 61 is deformed into an elliptical curled shape under slight vertical extrusion, so that the limiting part 61 relaxes the insulating film 6 during the process of being slightly bent, facilitating the movement of the insulating film 6 following the coil 42, the chip 41, and the rigid bearing plate 51, reducing the frictional tension of the insulating film 6 on the chip 41 and the coil 42 during the bending of the housing, and improving the protection of the chip 41 and the coil 42.

[0060] When the smart card housing continues to be bent, as Figure 13 shown in the lower side view in [reference], the flexible embedded strip 211 continues to vertically extrude the elliptical curled limiting part 61 to deform it so that the limiting part 61 is flattened into a plate shape, and then the limiting part 61 deforms to tighten the insulating film 6 to achieve secondary fixation. Thus, during the bending process of the smart card housing, the limiting part 61 first relaxes the insulating film 6 to facilitate the movement of the chip 41 and the coil 42 away from the position where the housing is bent. Subsequently, when the smart card housing is bent, the limiting part 61 is pressed into a plate shape to re-tighten the insulating film 6 to perform secondary tightening and fixation on the moved chip 41 and coil 42, further improving the use safety and service life of the chip 41.

[0061] Secondly, during the process of the smart card housing being bent horizontally, the movement of the rigid bearing plate 51 driving the chip 41 to move within the installation cavity 3 and the movement of the limiting part 61 being deformed by the flexible embedded strip 211 are carried out synchronously. As a result, the limiting part 61 is moved along the long side of the flexible clamping plate 5 while being squeezed on one side, further facilitating the movement of the chip 41 and the rigid bearing plate 51 within the installation cavity 3, and also avoiding the problem that the coil 42 breaks due to excessive pressure when moving through the bent part of the housing.

[0062] Furthermore, as Figure 6 shown, an arched part 2131 extending between the two insulating films 6 is arranged in the wrapping groove 213 to provide more stable support and limitation for the insulating film 6, further improving the installation stability of the chip 41 and the coil 42 between the insulating films 6.

[0063] As another embodiment provided by the present invention, the upper plate seat 11 and the lower plate seat 12 are symmetrically and linearly arrayed with abutting column parts 7 extending into the installation cavity 3, and the upper plate seat 11 and the lower plate seat 12 are joined together so that the abutting column parts 7 abut against and limit the deformation and expansion of the limiting part 61.

[0064] Specifically, an insertion groove 215 is formed on the flexible embedded strip 211, and a contact slope 214 is also provided on the flexible embedded strip 211, as Figure 7As shown, when the upper board seat 11 and the lower board seat 12 are assembled to install the flexible splint 5, the insulating film 6, the chip 41 and the coil 42 in the installation cavity 3, the ends of the abutting column parts 7 arranged in the upper board seat 11 and the lower board seat 12 all face the flexible splint 5 in the installation cavity 3, and as Figure 12 shown in the upper side view in, the fixing component is not yet assembled with the upper board seat 11 and the lower board seat 12. The limiting part 61 abuts against the abutting column part 7 due to its own elastic expansion, so that the abutting column part 7 can pre-press the insulating film 6 and the flexible splint 5 at this time, avoiding accidental movement of the chip 41 and the coil 42 when the fixing component is not installed, and facilitating actual installation and use.

[0065] When the rear end seat 23, the side blocking strip 22 and the front end seat 21 of the fixing component are sequentially spliced onto the upper board seat 11 and the lower board seat 12, the flexible embedding strip 211 gradually extends into the installation cavity 3 to squeeze the limiting part 61 through the wrapping groove 213, so that the limiting part 61 deforms and contracts to abut in the wrapping groove 213, and the end of the abutting column part 7 abuts in the extending groove 215 of the flexible embedding strip 211. Then, the abutting column part 7 further limits the flexible splint 5 and the insulating film 6 through the flexible embedding strip 211, improving the limiting stability of the chip 41 and the coil 42. And the contact slope 214 of the flexible embedding strip 211 also abuts against the slope part 53 of the flexible splint 5 to further realize the abutting support for the flexible splint 5, thereby improving the support and limiting stability of the chip 41, the coil 42 and the flexible splint 5 in the smart card shell during use, and improving the service life of the smart card.

[0066] When the smart card shell is bent horizontally to form a crease substantially perpendicular to the side blocking strip 22, then as Figure 7 shown, the abutting column part 7 on the upper board seat 11 and the abutting column part 7 on the vertical lower board seat 12 will approach each other and squeeze the flexible embedding strip 211 to achieve buffering when the smart card shell is bent, thereby improving the anti-bending property and service life of the smart card shell.

[0067] Furthermore, friction nails 2151 are linearly arrayed in the extending groove 215. When the flexible embedding strip 211 moves into the installation cavity 3, several abutting column parts 7 and several friction nails 2151 are rubbed and separated in sequence to generate vibration, thereby facilitating the stable wrapping of the limiting part 61 by the flexible embedding strip 211, and making the flexible embedding strip 211 vibrate to increase the contact area between the contact slope 214 and the slope part 53, improving the support stability of the flexible embedding strip 211 for the flexible splint 5 and facilitating actual installation.

[0068] As another embodiment provided by the present invention, the end of the abutment column portion 7 extends into the mounting cavity 3 in an inclined manner with its back to the side through the groove 93, and the upper plate seat 11 and the lower plate seat 12 are bent obliquely so that the abutment column portion 7 of the upper plate seat 11 and the abutment column portion 7 of the lower plate seat 12 are offset and close to each other.

[0069] Specifically, Figure 4 As shown, the abutting column 7 extends into the installation cavity 3 in an inclined state so that the end of the abutting column 7 faces away from the through slot 93, so that the flexible embedding strip 211 can be moved into the installation cavity 3 along the through slot 93, which is convenient for actual assembly and use. And because the smart card shell may also form a crease with an angle less than 90 degrees with the side guard strip 22 when it is bent laterally, that is, the smart card shell is not symmetrically bent laterally, but is randomly bent in an inclined state. In the process of the smart card shell being bent in an inclined state, since there is a mounting cavity 3 between the upper plate seat 11 and the lower plate seat 12, there is a spacing between the upper plate seat 11 and the lower plate seat 12, and one of the upper plate seat 11 or the lower plate seat 12 is bent and arched in an inclined state toward the installation cavity 3, thereby pushing the hard support plate 51 to drive the chip 41 and the coil 42 to move and deflect in an inclined state;

[0070] Furthermore, the abutment column 7 of the upper plate seat 11 and the abutment column 7 of the lower plate seat 12 are offset and close to each other, so that the abutment column 7 is offset and squeezes the flexible embedding strip 211 and the limiting portion 61 to increase the squeezing stroke of the limiting portion 61, thereby increasing the stroke of the limiting portion 61 to deform and relax the insulating film 6, thereby achieving a greater degree of relaxation of the insulating film 6 when the smart card shell is tilted and bent than when the smart card shell is directly bent horizontally, further facilitating the movement of the chip 41 and the coil 42 when the smart card shell is tilted and bent, thereby improving the protection of the chip 41.

[0071] Since the smart card shell will form a fold with a certain angle to the side guard bar 22 when it is tilted and bent, the straight line formed by the squeezed limiting parts 61 at both ends of the fold of the smart card shell is no longer perpendicular to the side guard bar 22, so that the squeezed limiting parts 61 will first release the insulating film 6 to relax and tilt to match the tilt deflection of the chip 41, and then the limiting parts 61 will be compressed and tighten the inclined insulating film 6 to fix the inclined chip 41 for a second time and limit it, thereby realizing the automatic movement, tilting and fixing of the chip 41 when the smart shell is tilted and bent. Further improve the protection of the chip 41 and the coil 42.

[0072] Working principle: The upper plate base 11 and the lower plate base 12 are assembled with each other to install the flexible clamping plate 5, the insulating film 6, the chip 41 and the coil 42 in the installation cavity 3. The limiting part 61 abuts against the abutting column part 7 due to its own elastic expansion. The flexible clamping plate 5 and the rigid bearing plate 51 complete the floating clamping and fixing of the chip 41 and the coil 42 in the installation cavity 3. When the rear end seat 23, the side baffle 22 and the front end seat 21 of the fixing component are sequentially spliced on the upper plate base 11 and the lower plate base 12, the flexible embedding strip 211 gradually extends into the installation cavity 3 to squeeze the limiting part 61 through the wrapping groove 213, so that the limiting part 61 deforms and contracts to abut in the wrapping groove 213, and the end of the abutting column part 7 abuts in the extending groove 215 of the flexible embedding strip 211. Furthermore, the abutting column part 7 further limits the flexible clamping plate 5 and the insulating film 6 through the flexible embedding strip 211. Finally, the fixing bolt 24 passes through the front end seat 21 and the side baffle 22 and is threadedly connected to the rear end seat 23 to complete the overall locking and fixing;

[0073] When the smart card housing is bent laterally to form a crease substantially perpendicular to the side baffle 22, the abutting column parts 7 on the upper plate base 11 and the abutting column parts 7 on the vertical lower plate base 12 will approach each other and squeeze the flexible embedding strip 211. The upper plate base 11 and the lower plate base 12 are driven to bend, causing the interior of the installation cavity 3 to deform, that is, one of the upper plate base 11 or the lower plate base 12 bends and extends into the installation cavity 3. At this time, the apex of the upper plate base 11 or the lower plate base 12 that bends and extends into the installation cavity 3 will squeeze against the convex arc contact surface 511 of the rigid bearing plate 51. Furthermore, the bent upper plate base 11 or lower plate base 12 squeezes the rigid bearing plate 51 to push the rigid bearing plate 51 and the chip 41 to move away from the bending point. The limiting part 61 relaxes the insulating film 6 first to facilitate the movement of the chip 41 and the coil 42 away from the position where the housing is bent. Subsequently, when the smart card housing is bent, the limiting part 61 is pressed into a plate shape, causing the insulating film 6 to be re-tightened to perform secondary tensioning and fixing on the moved chip 41 and coil 42.
