This not only affects the user experience but also increases the usage cost of smart cards. Therefore, developing a smart card structure with high stability and not easily deformed has important practical significance and commercial value. Summary of the Invention

Embodiment

[0023] As Figures 1-5As shown in the figure, the present utility model provides an intelligent card structure that is not easily deformed. The structure sequentially includes a base layer 1, a coil 6, a filling layer 2, and a surface layer 7 from the inside to the outside. The upper and lower layers of the base layer 1 are provided with skeletons 3 for reinforcement. The gap between the base layer 1 and the skeletons 3 is filled with the filling layer 2. The base layer 1 is also provided with a bending portion 5, and the bending portion 5 is located outside the coverage of the skeletons 3. Reinforcing members 4 are fixedly connected to both the upper and lower surfaces at the four corners of the base layer 1.

[0024] The skeletons 3 provided on the upper and lower layers of the base layer 1 provide a firm support for the intelligent card, significantly enhancing the stability of the overall structure. The presence of the skeletons 3 enables the intelligent card to maintain its shape unchanged when facing external pressure or impact, effectively preventing the deformation of the card. The gap between the skeletons 3 and the base layer 1 is filled with the filling layer 2, ensuring the tightness and integrity of the structure and further improving the durability of the intelligent card.

[0025] The bending portion 5 provided on the base layer 1 enables the intelligent card to have better flexibility and bending performance at the parts that need to be bent. This design allows the intelligent card to be bent limitedly when needed without breaking or being damaged at the bending part. Since the bending portion 5 is located outside the coverage of the skeletons 3, the skeletons 3 will not be subjected to excessive stress during bending, thus maintaining the stability of the overall structure.

[0026] The reinforcing members 4 fixedly connected to both the upper and lower surfaces at the four corners of the base layer 1 can significantly enhance the strength of the intelligent card in these key areas. The four corners are the parts of the intelligent card that are prone to pressure and impact during use. The presence of the reinforcing members 4 can effectively resist these external forces and prevent the intelligent card from deforming or being damaged at the four corners.

[0027] An elastic member 8 for increasing elasticity is wrapped around the outer layer of the coil 6, and the elastic member 8 is spirally wound on the surface of the coil 6.

[0028] The spirally wound elastic member 8 can endow the coil 6 with a certain elasticity, enabling it to have a certain buffering ability when facing external pressure or impact. This elasticity can effectively prevent the coil 6 from deforming or being damaged when subjected to external forces, thereby protecting the integrity and functionality of the coil 6.

[0029] Since the intelligent card may be subjected to various external forces during use, such as bending, extrusion, etc., the coil 6, as one of the core components of the intelligent card, its safety is crucial. The spirally wound elastic member 8 can closely adhere to the surface of the coil 6, forming a protective layer, effectively preventing the direct contact between the coil 6 and the outside world and reducing the risk of its damage.

[0030] The surface of the coil 6 is covered with a coating 9, and the coating 9 is an EMI coating 9.

[0031] By covering the EMI coating 9, the intrusion of external electromagnetic waves and the leakage of internal electromagnetic waves can be effectively blocked, thereby protecting the electronic components inside the smart card from electromagnetic interference.

[0032] The skeleton 3 is a rhombic fishbone-shaped elastic structure, and the skeleton 3 is a thermoplastic polyurethane skeleton 3.

[0033] The rhombic fishbone-shaped design enables the skeleton 3 to have a certain elasticity while maintaining the structural strength. This design not only increases the impact resistance and compressive resistance of the smart card, but also when subjected to external forces, the skeleton 3 can deform to a certain extent, absorb and disperse the external forces, thereby preventing the overall breakage or deformation of the smart card. The thermoplastic polyurethane material itself has excellent mechanical properties and chemical resistance, which enables the skeleton 3 to maintain its stability and functionality for a long time and extends the service life of the smart card.

[0034] The bending part 5 is a plurality of grooves with an inverted triangular cross-section, and the grooves are arranged inside the filling layer 2.

[0035] The inverted triangular groove design allows the smart card to have a certain bending ability at specific positions. When the smart card is subjected to external forces, these grooves can serve as the guidance for bending, enabling the smart card to bend at these positions without accidental breakage or deformation at other places.

[0036] Since the grooves are located inside the filling layer 2, they can effectively disperse and relieve the impact of external forces on the main structure of the smart card. When the smart card is subjected to pressure or bending force, the grooves in the filling layer 2 can absorb part of the force and reduce the direct impact on the base layer 1 and other components. It helps to maintain the integrity and stability of the overall structure of the smart card.

[0037] The thickness of the reinforcement 4 is the same as that of the skeleton 3. This makes the entire smart card structure uniform in thickness, avoiding stress concentration or structural imbalance caused by uneven thickness. This structure helps to improve the overall stability and anti-deformation ability of the smart card.

[0038] The reinforcement 4 is usually located at the corners of the smart card, and these positions are where the smart card is prone to external force impact and extrusion during use. The fact that the reinforcement 4 has the same thickness as the skeleton 3 means that they have the same strength and hardness, and can jointly bear and disperse these external forces, thereby protecting the smart card from damage.

[0039] When the embodiment of the present application is in use: The skeletons 3 arranged on the upper and lower layers of the base layer 1 can significantly enhance the structural stability of the entire smart card. The skeleton 3, as a reinforcement layer, can effectively resist external pressure or impact, preventing the smart card from deforming or being damaged during use. At the same time, the rhombic fishbone-shaped elastic structure design of the skeleton 3 can absorb part of the impact force, further improving the impact resistance of the smart card.

[0040] The bending portion 5 provided on the base layer 1 enables the smart card to have better flexibility and bending performance at the position where bending is required. Since the bending portion 5 is outside the coverage of the skeleton 3, the skeleton 3 will not be subjected to excessive stress during bending, thereby maintaining the stability of the overall structure. In addition, the design of multiple grooves with an inverted triangular cross-section can further increase the flexibility of the bending portion 5, making the smart card smoother during bending and not easily broken.

[0041] The elastic member 8 wrapped around the outer layer of the coil 6 can, on the one hand, increase the elasticity of the coil 6 to prevent it from deforming when stressed, and on the other hand, protect the coil 6 from the influence of the external environment. At the same time, the EMI coating 9 covering the surface of the coil 6 can effectively shield electromagnetic wave interference, protect the electronic components inside the smart card from the influence of electromagnetic interference, and ensure the normal operation of the smart card.

[0042] The reinforcement members 4 fixedly connected to both the upper and lower surfaces at the four corners of the base layer 1 can further increase the overall strength of the smart card. The reinforcement members 4 have the same thickness as the skeleton 3, enabling the smart card to have good impact resistance and compressive resistance in all directions.
