DETAILED DESCRIPTION

[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the present disclosure clearer, the technical scheme of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without any inventive effort fall within the protection scope of the present disclosure.

[0036] As shown in Figure 1, a smart card shell structure with an IC chip includes a chip 41 and a coil 42 symmetrically connected to the chip 41, and further includes: Figures 1-13

[0037] ​The mounting assembly includes an upper plate base 11 and a lower plate base 12. The upper plate base 11 and the lower plate base 12 are joined in parallel to form a mounting cavity 3 for mounting the chip 41 and the coil 42. Both the upper plate base 11 and the lower plate base 12 are provided with placement slots 92 for fixing the card surface.

[0038] The fixing assembly includes a front seat 21, a side baffle 22 and a rear seat 23. The rear seat 23, the side baffle 22 and the front seat 21 are sequentially inserted into the periphery of the upper plate seat 11 and the lower plate seat 12 to form a smart card housing.

[0039] Specifically, it also includes fixing bolts 24, such as Figure 9 As shown, several limiting holes 94 are provided on the periphery of the upper plate seat 11 and the lower plate seat 12, while several limiting posts 95 are provided on the front end seat 21, the side baffle 22 and the rear end seat 23. The rear end seat 23 is provided with a protruding plate 231, the side baffle 22 is provided with an abutment groove 221 and a insertion groove 222, and the front end seat 21 is provided with an insertion part 212. First, the upper plate seat 11 and the lower plate seat 12 can be assembled to install the chip 41 and the coil 42 into the mounting cavity 3. Then, the rear end seat 23 is inserted into the rear end periphery of the upper plate seat 11 and the lower plate seat 12 through the limiting posts 95. Then, the side baffle 22 is inserted into the periphery of both sides of the upper plate seat 11 and the lower plate seat 12 through the limiting posts 95. At this time, the abutment groove 221 of the side baffle 22 presses the protruding plate 231 tightly. Then, the front end seat 21 is inserted into the upper plate seat 11 and the lower end seat 12 through the limiting posts 95. The front periphery of the plate base 12 allows the insertion part 212 to be inserted into the insertion groove 222 of the side stop strip 22. After the end base 23, the side stop strip 22 and the front base 21 are spliced ​​with the periphery of the upper plate base 11 and the lower plate base 12, the fixing bolts 24 are threaded through the front base 21 and the side stop strip 22 and connected to the rear base 23 to complete the overall locking and fixing. At this time, the upper plate base 11, the lower plate base 12, the front base 21, the side stop strip 22 and the rear base 23 are spliced ​​together to form the smart card housing.

[0040] The chip 41 and coil 42 are mounted by parallel splicing of the upper plate base 11 and the lower plate base 12 to increase the shell thickness of the smart card shell structure. The presence of the rear end base 23, the side baffle 22 and the front end base 21 can also improve the overall bending resistance of the smart card shell, thereby improving the protection of the smart card shell structure for the internally installed chip 41 and coil 42, and improving the suitability of the smart card shell for use by children.

[0041] Also include the transparent cover plate 91 arranged on the surface of the placement slot 92, when the smart card shell structure installation is completed, can be through loosening the fixing bolt 24 to take out the front end seat 21, thereby exposing the upper plate seat 11 and the placement slot 92 of the lower plate seat 12, and can be inserted into the required different card surface to complete the card surface replacement of the smart card shell in the placement slot 92, and then through the fixing bolt 24 again the front end seat 21 and the upper plate seat 11 and the lower plate seat 12 are fixed and locked, complete the recombination of the smart card shell, and can use the transparent cover plate 91 to observe and protect the card surface in the placement slot 92, and then use the placement slot 92 of the upper plate seat 11 and the lower plate seat 12 and the detachable front end seat 21, side bar 22 and rear end seat 23 to realize the replacement of the card surface of the smart card shell, improve the degree of children's love for smart card to reduce the probability of smart card bending, further improve the applicability of the smart card shell for children.

[0042] In the above scheme, the chip 41 and the coil 42 are installed by parallel combination of the upper plate seat 11 and the lower plate seat 12 to improve the shell thickness of the smart card shell structure, and the existence of the rear end seat 23, the side bar 22 and the front end seat 21 can also improve the overall bending resistance of the smart card shell, thereby improving the protection of the chip 41 and the coil 42 installed in the smart card shell structure, and using the placement slot 92 of the upper plate seat 11 and the lower plate seat 12 and the detachable front end seat 21, side bar 22 and rear end seat 23 to realize the replacement of the card surface of the smart card shell, improve the degree of children's love for smart card to reduce the probability of smart card bending, further improve the applicability of the smart card shell for children.

[0043] As another embodiment provided by the application, the flexible clamp plate 5 symmetrically arranged in the installation cavity 3, both ends of the flexible clamp plate 5 are fixedly connected in the installation cavity 3, so that the hard supporting plate 51 arranged in the middle of the flexible clamp plate 5 clamps the chip 41, and the flexible clamp plate 5 clamps the coil 42.

[0044] Specifically, as Figure 2As shown in the figure, the two flexible clamping plates 5 are arranged in the mounting cavity 3 parallel to the upper plate seat 11 and the lower plate seat 12, and the longitudinal two ends of the flexible clamping plate 5 are fixed in the mounting cavity 3, so that the two flexible clamping plates 5 are clamped on the vertical two sides of the coil 42, and the rigid supporting plate 51 of the flexible clamping plate 5 is clamped on the vertical two sides of the chip 41. The flexible clamping plate 5 and the rigid supporting plate 51 are used to complete the suspension clamping and fixing of the chip 41 and the coil 42 in the mounting cavity 3, so as to avoid the problem that the chip 41 or the coil 42 is damaged by torsion when the smart card shell is slightly bent by external force, and improve the installation protection of the chip 41 and the coil 42. The rigid supporting plate 51 is used to clamp and fix the chip 41, and the rigid supporting plate 51 is tensioned by the flexible clamping plate 5 to suspend in the mounting cavity 3, so that the rigid supporting plate 51 can clamp and fix the chip 41 while further avoiding the chip 41 from being bent by external force and the problem that the chip 41 is damaged by impacting the upper plate seat 11 and the lower plate seat 12, thereby further improving the protection of the chip 41.

[0045] Further, the longitudinal two ends of the flexible clamping plate 5 are provided with through holes 52, the lower plate seat 12 is provided with a supporting portion 121 and a through column 122, the upper plate seat 11 and the lower plate seat 12 are matched with each other to make the through column 122 pass through the through hole 52, and the supporting portion 121 and the upper plate seat 11 clamp the longitudinal two ends of the two flexible clamping plates 5. Figure 10 As shown in the figure, the parallel long side direction of the flexible clamping plate 5 is the longitudinal direction, and the parallel short side direction is the transverse direction. Figure 8 As shown in the figure, when the upper plate seat 11 and the lower plate seat 12 are matched, the flexible clamping plate 5, the rigid supporting plate 51, the chip 41 and the coil 42 are all located in the mounting 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 fixing and limiting of the two ends of the flexible clamping plate 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 side, thereby further improving the fixing stability of the two ends of the flexible clamping plate 5.

[0046] And since the rigid supporting 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 lengthen to realize the buffering during the movement of the chip 41, thereby further improving the protection of the chip 41.

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

[0048] Specifically, as shown in the figure, Figure 3As shown, at this time, the direction parallel to the flexible clamping plate 5 is horizontal, and the direction perpendicular to the flexible clamping plate 5 is vertical. The vertical side wall of the mounting cavity 3 and the flexible clamping plate 5 have a predetermined spacing, and the flexible clamping plate 5 and the upper plate seat 11 or the lower plate seat 12 have a predetermined spacing, so that when the flexible clamping plate 5 is deformed by external inertia or impact, the possibility of the flexible clamping plate 5 or the hard supporting plate 51 impacting the upper plate seat 11 or the lower plate seat 12 is reduced, thereby further achieving the protection and buffering of the chip 41 and the coil 42, and improving the service life of the chip 41. The predetermined spacing between the flexible clamping plate 5 and the upper plate seat 11 or the lower plate seat 12 is 2-3 mm.

[0049] Secondly, as shown in Figure 10 , the hard supporting plate 51 is provided with a convex arc abutting surface 511, and as shown in Figure 3 , the convex arc abutting surface 511 is located on the side of the hard supporting plate 51 away from the chip 41. If the surface of the convex arc abutting surface 511 of the hard supporting plate 51 moves and impacts on the upper plate seat 11 or the lower plate seat 12 when the flexible clamping plate 5 is deformed by external inertia or impact, the existence of the convex arc abutting surface 511 can improve the compression and bending strength of the hard supporting plate 51, thereby further improving the protection of the chip 41 by the hard supporting plate 51.

[0050] When the smart card shell is bent due to improper use, as shown in Figure 2 , the cross section of the smart card shell is still rectangular. The shape of the smart card shell makes the smart card shell more easily bent in the transverse direction to form a crease substantially perpendicular to the side stop bar 22. The existence of the two symmetrically arranged coils 42 on the chip 41 makes the coil 42 on one side still able to be used normally to drive the chip 41 even if the coil 42 on one side is damaged by bending. The upper plate seat 11 and the lower plate seat 12 are bent by driving to deform the inside of the mounting cavity 3, that is, one of the upper plate seat 11 or the lower plate seat 12 bends into the mounting cavity 3. At this time, the vertex of the upper plate seat 11 or the lower plate seat 12 bent into the mounting cavity 3 will press on the convex arc abutting surface 511 of the hard supporting plate 51, and then the bent upper plate seat 11 or lower plate seat 12 will press the hard supporting plate 51 to push the hard supporting plate 51 and the chip 41 away from the bending point. At the same time, the flexible clamping plate 5 also deforms adaptively to contract or lengthen to cooperate with the movement of the hard supporting plate 51 and the chip 41 in the mounting cavity 3, so that the chip 41 can move in the mounting cavity 3 to leave the bending position, thereby further improving the protection of the chip 41.

[0051] As another embodiment of the present application, an insulating film 6 is also provided, which is symmetrically arranged in the mounting cavity 3 to separate the chip 41 and the coil 42 from the hard supporting plate 51 and the flexible clamping plate 5.

[0052] Specifically, as shown in Figure 3As shown, the insulating film 6 is arranged between the flexible clamping plate 5 and the chip 41. The insulating film 6 separates the chip 41 from the rigid support plate 51 and the coil 42 from the flexible clamping plate 5, thus achieving 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, if the smart card casing is bent, the rigid support plate 51 will be squeezed and move within the mounting cavity 3, changing its position. The flexible clamping plate 5 will follow the rigid support plate 51 to adapt to the deformation. The insulating film 6 separates the flexible clamping plate 5 from the coil 42, thus preventing the coil 42 from wrinkling or breaking due to friction during the deformation, contraction, or stretching of the flexible clamping plate 5. This further improves the protection of the coil 42, ensuring that the coil 42 and chip 41 can still function normally after the smart card casing is bent, improving the stability and applicability of the smart card and making it easier for children to use.

[0053] If 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 will be bent and damaged in one direction under pressure. That is, one plate seat 11 is concave and the other is convex. At this time, the convex plate seat can be pressed back to a horizontal position, while the concave plate seat will remain concave without manual reset. This avoids the problem of accelerated breakage caused by repeated bending of the plate seat. The plate seat that has been reset to a horizontal position can facilitate the actual use and placement of the smart card housing, further improving the durability of the smart card housing. After being bent, it can be manually adjusted to continue to be used. Furthermore, the concave part of the concave plate base can squeeze the rigid support plate 51 and the chip 41 away from the bend of the smart housing, and keep the chip 41 and the rigid support plate 51 in the mounting cavity 3 away from the bend, so as to avoid damage to the chip 41 caused by possible secondary bending of the housing, and further improve the protection of the chip 41.

[0054] As another embodiment of the present invention, the insulating film 6 has symmetrically connected limiting portions 61 extending to and abutting against the two sides of the flexible clamping plate 5 to laterally limit the insulating film 6.

[0055] Specifically, such as Figure 10 As shown, the insulating film 6 extends to both ends of the long side of the flexible clamping plate 5 and is provided with limiting portions 61, such as... Figure 6 As shown, the limiting portion 61 extends and abuts against the ramp portion 53 on the long side of the flexible clamping plate 5, thereby fixing the insulating film 6 in the short side direction of the flexible clamping plate 5. This prevents the insulating film 6 from moving laterally and detaching from the chip 41 and the rigid support plate 51, thus avoiding direct contact between the chip 41 and the rigid support plate 51 and improving the insulation protection stability of the insulating film 6 for the chip 41. The limiting portion 61 and the ramp portion 53 abut against each other to improve the stability of the lateral limiting arrangement of the insulating film 6.

[0056] As another embodiment provided by the present application, the flexible embedded strip 211 is symmetrically arranged on the front end seat 21, and the through slots 93 are opened on the upper plate seat 11 and the lower plate seat 12 and are matched with each other, and the flexible embedded strip 211 moves into the installation cavity 3 along the through slots 93 to form a high-pressure environment in the installation cavity 3.

[0057] Specifically, as shown in Figure 9 When the upper plate seat 11 and the lower plate seat 12 are matched 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 matched with each other, and then the rear end seat 23, the side blocking strip 22 and the front end seat 21 can be sequentially spliced to splice the smart card shell structure, and when the front end seat 21 is installed on the upper plate seat 11 and the lower plate seat 12, the flexible embedded strip 211 moves into the through slots 93 and gradually moves into the installation cavity 3, and at the same time, the flexible embedded strip 211 also abuts and seals 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, avoiding the invasion of external water vapor or dust into the installation cavity 3 to cause 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 embedded strip 211 gradually moves into the installation cavity 3, it also reduces the volume of the installation cavity 3 to increase the air pressure in the installation cavity 3 to form a high-pressure environment, thereby further avoiding the invasion of external water vapor or dust into the installation cavity 3.

[0058] As another embodiment provided by the present application, the limiting portion 61 is curled in a vortex line shape, the flexible embedded strip 211 moves 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 embedded strip 211 extrudes the limiting portion 61 to be pressed and deformed into an elliptical shape to relax the insulating film 6, and then the limiting portion 61 continues to be pressed and deformed into a plate shape to tighten the insulating film 6.

[0059] Specifically, as shown in Figure 6 The limiting portion 61 at both ends of the insulating film 6 is a film roll curled in a vortex line shape, when the upper plate seat 11, the lower plate seat 12, the rear end seat 23, the side blocking strip 22 and the front end seat 21 are spliced to form the smart card shell structure, the flexible clamping plate 5, the insulating film 6, the chip 41 and the coil 42 are clamped and fixed in the installation cavity 3, and the flexible embedded strip 211 is provided with a wrapping slot 213, and the limiting portion 61 on the two insulating films 6 is wrapped in the wrapping slot 213 of the flexible embedded strip 211, when the smart card shell is bent, first, the smart card shell is slightly bent, and the flexible embedded strip 211 at the bent portion is also slightly bent to extrude the limiting portion 61, that is, as shown in Figure 13As shown in the upper side view of Fig. 1, the originally round crimped limiting part 61 is slightly vertically extruded to be elliptical crimped, so that the limiting part 61 relaxes the insulating film 6 during the slight bending to facilitate the movement of the insulating film 6 following the coil 42, the chip 41 and the hard supporting plate 51, reduces the frictional tension of the insulating film 6 on the chip 41 and the coil 42 during the bending of the shell, and improves the protection of the chip 41 and the coil 42.

[0060] As shown in the lower side view of Fig. 1, when the smart card shell continues to bend, the flexible embedded strip 211 continues to vertically extrude the elliptical crimped limiting part 61 to be flattened to be a plate, and then the limiting part 61 is deformed to tighten the insulating film 6 to achieve secondary fixation, so that the limiting part 61 relaxes the insulating film 6 to facilitate the movement of the chip 41 and the coil 42 away from the position of the shell subjected to bending, and then when the smart card shell is bent, the limiting part 61 is pressed to be a plate to make the insulating film 6 be re-tightened to achieve secondary fixation of the moved chip 41 and coil 42, further improving the safety and service life of the chip 41.

[0061] Further, as shown in Fig. 2, the hard supporting plate 51 drives the movement of the chip 41 in the installation cavity 3, and the limiting part 61 is deformed by the extrusion of the flexible embedded strip 211, which are synchronous, so that the limiting part 61 is extruded while moving along the long side of the flexible clamping plate 5, further facilitating the movement of the chip 41 and the hard supporting plate 51 in the installation cavity 3, and avoiding the problem that the coil 42 is broken due to excessive pressure when moving through the bent position of the shell.

[0062] Further, as shown in Fig. 2, the hard supporting plate 51 drives the movement of the chip 41 in the installation cavity 3, and the limiting part 61 is deformed by the extrusion of the flexible embedded strip 211, which are synchronous, so that the limiting part 61 is extruded while moving along the long side of the flexible clamping plate 5, further facilitating the movement of the chip 41 and the hard supporting plate 51 in the installation cavity 3, and avoiding the problem that the coil 42 is broken due to excessive pressure when moving through the bent position of the shell. Figure 6 Further, as shown in Fig. 2, the hard supporting plate 51 drives the movement of the chip 41 in the installation cavity 3, and the limiting part 61 is deformed by the extrusion of the flexible embedded strip 211, which are synchronous, so that the limiting part 61 is extruded while moving along the long side of the flexible clamping plate 5, further facilitating the movement of the chip 41 and the hard supporting plate 51 in the installation cavity 3, and avoiding the problem that the coil 42 is broken due to excessive pressure when moving through the bent position of the shell.

[0063] Specifically, the flexible embedded strip 211 is provided with an extrusion groove 215, and the flexible embedded strip 211 is further provided with a contact slope 214, as shown in Fig. 3.

[0064] Figure 7 ​​As shown, when the upper plate base 11 and the lower plate base 12 are assembled to install the flexible clamping plate 5, the insulating film 6, the chip 41 and the coil 42 into the installation cavity 3, the end of the abutting column part 7 arranged in the upper plate base 11 and the lower plate base 12 is all towards the flexible clamping plate 5 in the installation cavity 3, and as shown in the upper side view in Figure 12 , the fixing assembly has not been assembled with the upper plate base 11 and the lower plate base 12, the limiting part 61 abuts on the abutting column part 7 due to the elastic expansion of itself, and further makes the abutting column part 7 at this time to form pre-pressing on the insulating film 6 and the flexible clamping plate 5, avoiding the accidental movement of the chip 41 and the coil 42 when the fixing assembly is not installed, facilitating the actual installation and use.

[0065] When the rear end base 23, the side blocking strip 22 and the front end base 21 of the fixing assembly are sequentially assembled 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 extrude the limiting part 61 through the wrapping groove 213, so that the limiting part 61 is deformed and shrinks 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, further making the abutting column part 7 to limit the flexible clamping plate 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 on the slope part 53 of the flexible clamping plate 5 to further realize the abutting support of the flexible clamping plate 5, thereby improving the support and limiting stability of the chip 41, the coil 42 and the flexible clamping plate 5 of the smart card shell during use, and improving the service life of the smart card.

[0066] If the smart card shell is bent transversely to form a crease substantially perpendicular to the side blocking strip 22, as shown in Figure 7 , the abutting column part 7 on the upper plate base 11 and the abutting column part 7 on the vertical lower plate base 12 will approach each other and extrude the flexible embedding strip 211 to realize the buffering when the smart card shell is bent, thereby improving the bending resistance and service life of the smart card shell.

[0067] Further, a plurality of friction nails 2151 are linearly arranged in the extending groove 215, when the flexible embedding strip 211 moves into the installation cavity 3, a plurality of abutting column parts 7 and a plurality of friction nails 2151 sequentially rub and separate to generate vibration, thereby facilitating the stable wrapping of the flexible embedding strip 211 on the limiting part 61, and making the flexible embedding strip 211 vibrate to increase the contact area of the contact slope 214 and the slope part 53, improve the support stability of the flexible embedding strip 211 on the flexible clamping plate 5, and facilitate the actual installation.

[0068] As another embodiment provided by the present application, the end of the abutting column part 7 is inclinedly extended into the installation cavity 3, the upper plate base 11 and the lower plate base 12 are bent to make the abutting column part 7 of the upper plate base 11 and the abutting column part 7 of the lower plate base 12 abut each other in dislocation.

[0069] Specifically, as shown in the figure, Figure 4 the abutting column part 7 is inclinedly extended into the installation cavity 3 to make the end of the abutting column part 7 face away from the through groove 93, so as to facilitate the flexible embedded strip 211 to move along the through groove 93 and be installed into the installation cavity 3, and facilitate the actual assembly and use. And since the smart card shell can also form a crease with the side blocking strip 22 at an angle less than 90 degrees when being bent laterally, that is, the smart card shell is not symmetrically bent laterally, but randomly bent obliquely. Therefore, during the oblique bending of the smart card shell, since the installation cavity 3 is provided between the upper plate base 11 and the lower plate base 12 to make the upper plate base 11 and the lower plate base 12 have a spacing, one of the upper plate base 11 and the lower plate base 12 is bent and arched obliquely into the installation cavity 3, and further pushes the hard supporting plate 51 to move and deflect the chip 41 and the coil 42 obliquely;

[0070] and the abutting column part 7 of the upper plate base 11 and the abutting column part 7 of the lower plate base 12 abut each other in dislocation, so as to make the abutting column part 7 extrude the flexible embedded strip 211 and the limiting part 61 in dislocation to increase the extrusion stroke of the limiting part 61, and further increase the stroke of the deformation relaxation of the limiting part 61 to the insulating film 6, so as to realize that the relaxation degree of the insulating film 6 when the smart card shell is obliquely bent is greater than that when the smart card shell is directly bent laterally, and further facilitate the movement of the chip 41 and the coil 42 when the smart card shell is obliquely bent, and improve the protection of the chip 41.

[0071] And since the smart card shell can form a crease with the side blocking strip 22 at an angle when being bent obliquely, the straight line connected by the extruded limiting parts 61 at both ends of the crease of the smart card shell is no longer perpendicular to the side blocking strip 22, so that the extruded limiting part 61 will first relax the insulating film 6 to be obliquely arranged to cooperate with the oblique deflection of the chip 41, and then the limiting part 61 will be pressed to tighten the obliquely arranged insulating film 6 to fix and limit the obliquely arranged chip 41 again, so as to realize the automatic movement, oblique deflection and fixation of the chip 41 when the smart card shell is obliquely bent. Further improve the protection of the chip 41 and the coil 42.

[0072] Working principle: the upper plate seat 11 and the lower plate seat 12 are assembled to 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 is in contact with the contact column part 7 due to the expansion of its elasticity, the flexible clamping plate 5 and the hard supporting plate 51 complete the suspension clamping and fixing of the chip 41 and the coil 42 in the installation cavity 3, and then the rear end seat 23, the side blocking strip 22 and the front end seat 21 of the fixed assembly are sequentially assembled on the upper plate seat 11 and the lower plate seat 12, the flexible embedded strip 211 gradually extends into the installation cavity 3 to extrude the limiting part 61 through the wrapping groove 213, so that the limiting part 61 is deformed and shrinks to be in contact with the wrapping groove 213, and the end of the contact column part 7 is in contact with the extending groove 215 of the flexible embedded strip 211, so that the contact column part 7 further limits the flexible clamping plate 5 and the insulating film 6 through the flexible embedded strip 211, and finally the fixed bolt 24 is screwed on the rear end seat 23 through the front end seat 21 and the side blocking strip 22 to complete the overall locking and fixing.

[0073] If the smart card shell is bent transversely to form a crease substantially perpendicular to the side blocking strip 22, the contact column part 7 on the upper plate seat 11 and the contact column part 7 on the vertical lower plate seat 12 will approach each other and extrude the flexible embedded strip 211, the upper plate seat 11 and the lower plate seat 12 are driven to bend and 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 vertex of the upper plate seat 11 or the lower plate seat 12 bending and extending into the installation cavity 3 extrudes the convex arc contact surface 511 of the hard supporting plate 51, so that the bent upper plate seat 11 or lower plate seat 12 extrudes the hard supporting plate 51 to push the hard supporting plate 51 and the chip 41 away from the bending point, and the limiting part 61 allows the insulating film 6 to relax first so that the chip 41 and the coil 42 move away from the position of the bending of the shell, and then when the smart card shell is bent, the limiting part 61 is pressed to be plate-shaped, so that the insulating film 6 is re-tightened to fix the moved chip 41 and coil 42 again.

[0074] The above only describes certain exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present application.
