Description

Technical Field

[0001] The utility model relates to the technical field of school library cards, and particularly relates to an RFID library card with good anti-bending performance. Background Art

[0002] At present, library cards are usually used in school libraries to facilitate librarians to record borrowing information and register quickly. Moreover, they also serve as the basis for borrowing and returning books. Library cards can also be used as meal cards, water cards, electricity cards, etc. in schools. Therefore, library cards are relatively important for students in this school. Generally, library cards are made of plastic materials. During the use process by students, the library cards are easily bent and damaged, resulting in the inability to use the library cards, affecting the normal life of students. At the same time, frequently replacing library cards will also increase additional costs, leading to an increase in the economic pressure on students. Content of the Utility Model

[0003] The purpose of the utility model is to provide an RFID library card with good anti-bending performance, which has good anti-bending performance, is not easily broken and damaged during the use process, has a long service life, does not need to be frequently replaced, and reduces the economic pressure on students.

[0004] To solve the above technical problems, the utility model adopts the following solutions:

[0005] An RFID library card with good anti-bending performance, comprising a library card body. The library card body is in a card shape and is composed of a bottom plate and a panel. An RFID tag is fixed between the bottom plate and the panel, and an anti-bending component located between the bottom plate and the panel is arranged circumferentially around the RFID tag.

[0006] In this solution, the borrowing card body adopts a standard card size and shape, which is convenient for carrying and storing, and at the same time meets the reading requirements of the library management system. The borrowing card is composed of two main materials, namely the bottom plate and the panel. These two materials can be selected from plastics and composite materials with good strength and toughness to ensure the stability and durability of the overall structure. The bottom plate and the panel can be firmly connected by bonding, hot pressing or other methods. The RFID tag is fixed between the bottom plate and the panel to ensure seamless docking with the library RFID system while not affecting the appearance and feel of the borrowing card. The RFID tag is used to store and transmit the identification information of the borrowing card, such as the borrower ID, book information, etc. In order to enhance the anti-bending performance of the borrowing card, an anti-bending component is designed. The anti-bending component is located around the RFID tag and forms a support structure between the bottom plate and the panel. The anti-bending component effectively prevents the borrowing card from breaking or the RFID tag from being damaged when being bent by external forces by dispersing the bending force, improving the local strength and stiffness. After adding the anti-bending component, the borrowing card body has good anti-bending performance, is not easily broken or damaged during use, has a long service life, and students do not need to replace it frequently, reducing the economic pressure on students.

[0007] Optionally, the anti-bending component includes a first anti-bending part and a second anti-bending part, and the first anti-bending part and the second anti-bending part intersect with each other to form a grid-shaped anti-bending component.

[0008] Optionally, the first anti-bending parts are horizontally and evenly spaced along the length direction of the borrowing card body, and the second anti-bending parts are vertically and evenly spaced along the width direction of the borrowing card body. The first anti-bending parts and the second anti-bending parts intersect with each other to form a rectangular grid-shaped anti-bending component.

[0009] Optionally, the first anti-bending parts are inclined and evenly spaced on both sides along one diagonal of the borrowing card body, and the second anti-bending parts are inclined and evenly spaced on both sides along the other diagonal of the borrowing card body. The first anti-bending parts and the second anti-bending parts intersect with each other to form a diamond grid-shaped anti-bending component.

[0010] Optionally, both the first anti-bending part and the second anti-bending part are strip-shaped.

[0011] Optionally, both the first anti-bending part and the second anti-bending part are square strips with solid or hollow structures.

[0012] Optionally, the RFID tag is adhered to the bottom plate by double-sided tape.

[0013] Optionally, after the bottom plate and the panel are closed and adhered, the anti-bending component and the RFID tag are sealed inside the borrowing card body.

[0014] Optionally, a fixing ring is adhesively bonded to the circumference of the borrowing card body, and the top and bottom surfaces of the fixing ring are both located outside the borrowing card body.

[0015] Optionally, the top surface of the panel is a downwardly concave curved surface, on which patterns and words are printed.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. In the present utility model, the anti-bending component is located around the RFID tag and forms a support structure between the bottom plate and the panel. By dispersing the bending force, improving the local strength and stiffness, the anti-bending component effectively prevents the library card from breaking or the RFID tag from being damaged when the library card is bent by an external force. After adding the anti-bending component, the library card body has good anti-bending performance, is not easily broken or damaged during use, has a long service life, and students do not need to replace it frequently, reducing the economic pressure on students.

[0018] 2. The top surface of the panel is a slightly downwardly concave curved surface, on which patterns and words related to the school are printed and a wear-resistant and scratch-resistant coating is applied. The design of the library card with a curved top surface can appropriately reduce the contact area with objects during long-term use compared to a library card with a flat top surface. In this way, the patterns and words on the top surface of the library card are not easily worn off. Description of the Drawings

[0027] Embodiment 1

[0028] An RFID library card with good anti-bending performance, including a library card body 1. The library card body 1 is in the shape of a card. The library card body 1 is composed of a bottom plate 102 and a panel 101. An RFID tag 4 is fixed between the bottom plate 102 and the panel 101. An anti-bending component 3 located between the bottom plate 102 and the panel 101 is provided circumferentially around the RFID tag 4.

[0029] In this embodiment, as Figure 1 shown, the library card body 1 adopts a standard card size and shape, which is convenient for carrying and storing, and at the same time meets the reading requirements of the library management system. The library card is composed of two main materials, namely the bottom plate 102 and the panel 101. These two materials can be selected from plastics and composite materials with good strength and toughness to ensure the stability and durability of the overall structure. The bottom plate 102 and the panel 101 can be firmly connected by bonding, hot pressing or other means, as Figure 2As shown, the RFID tag 4 is fixed between the bottom plate 102 and the panel 101, ensuring seamless docking with the library RFID system without affecting the appearance and feel of the library card. The RFID tag 4 is used to store and transmit the identification information of the library card, such as the borrower ID, book information, etc. To enhance the anti-bending performance of the library card, an anti-bending component 3 is designed. The anti-bending component 3 is located around the RFID tag 4 and forms a support structure between the bottom plate 102 and the panel 101. By dispersing the bending force, improving the local strength and stiffness, the anti-bending component 3 effectively prevents the library card from breaking or the RFID tag 4 from being damaged when the library card is bent by an external force. After adding the anti-bending component 3, the library card body 1 has good anti-bending performance, is not easily broken or damaged during use, has a long service life, and students do not need to replace it frequently, reducing the economic pressure on students.

[0030] Embodiment 2

[0031] Furthermore, the anti-bending component 3 includes a first anti-bending part 301 and a second anti-bending part 302. The first anti-bending part 301 and the second anti-bending part 302 intersect with each other to form a grid-like anti-bending component 3.

[0032] Specifically, the grid structure connects the anti-bending components together through multiple intersection points, forming a stable support system. This structure can improve the anti-bending, anti-twisting and anti-extrusion capabilities of the library card. When the library card is subjected to an external force, the grid structure can disperse the external force to multiple nodes and lines, thereby reducing the concentrated stress on a single part and reducing the risk of damage. The design of the grid-like anti-bending component 3 makes the library card more durable in daily use and can withstand frequent bending, friction and extrusion without being easily damaged. The first anti-bending part 301 and the second anti-bending part 302 can be made of materials with high strength and toughness, such as rigid plastics or composite materials, etc. These materials can ensure that the anti-bending component 3 is not easily deformed or broken when subjected to an external force. The first anti-bending part 301 and the second anti-bending part 302 can be designed into different shapes and sizes to adapt to the overall structure and design requirements of the library card. They can be cross-fixed together by welding, gluing or mechanical connection to form a grid-like structure.

[0033] Embodiment 3

[0034] Furthermore, the first anti-bending part 301 is evenly distributed at horizontal intervals along the length direction of the library card body 1, and the second anti-bending part 302 is evenly distributed at vertical intervals along the width direction of the library card body 1. The first anti-bending part 301 and the second anti-bending part 302 intersect with each other to form a rectangular grid-like anti-bending component 3.

[0035] Specifically, as Figure 3As shown, since the first bending resistance portion 301 and the second bending resistance portion 302 are evenly distributed along the length and width directions respectively, when the library card is subjected to an external force, the force can be evenly dispersed over the entire grid structure, thus avoiding the problem of local stress concentration. The rectangular grid structure has good stability and rigidity, and can effectively resist external forces such as bending, twisting and extrusion, protecting the overall structure of the library card from damage. The first bending resistance portion 301 is arranged along the length direction (i.e., the horizontal direction) of the library card body 1. A plurality of first bending resistance portions 301 are provided. The first bending resistance portion 301 can be a slender strip or sheet structure, and is evenly distributed at horizontal intervals to ensure stable support in the length direction.

[0036] The second bending resistance portion 302 intersects the first bending resistance portion 301 perpendicularly. Along the width direction (i.e., the vertical direction) of the library card body 1, a plurality of second bending resistance portions 302 are provided. Similarly, these bending resistance portions are also designed as slender strip or sheet structures and are evenly distributed at vertical intervals to provide additional support in the width direction. The first bending resistance portion 301 and the second bending resistance portion 302 intersect with each other on their respective distribution paths and are connected together by welding, bonding or other fixing means to form a complete rectangular grid structure. This cross-connection method enhances the integrity and stability of the grid structure, making the library card body 1 have good bending resistance performance, not easily broken or damaged during use, having a long service life, not requiring frequent replacement, and reducing the economic pressure on students.

[0037] Embodiment 4

[0038] Furthermore, the first bending resistance portion 301 is evenly distributed at inclined intervals along one diagonal of the library card body 1 towards both sides, and the second bending resistance portion 302 is evenly distributed at inclined intervals along the other diagonal of the library card body 1 towards both sides. The first bending resistance portion 301 and the second bending resistance portion 302 intersect with each other to form a rhombic grid-shaped bending resistance component 3.

[0039] Specifically, as Figure 4 shown, the first bending resistance portion 301 inclines towards both sides along one diagonal and is evenly spaced, and the second bending resistance portion 302 inclines evenly towards both sides along the other diagonal. The grid structure formed by the intersection of the first bending resistance portion 301 and the second bending resistance portion 302 has a plurality of rhombic units. This structure provides uniform support in multiple directions, enhancing the bending resistance performance of the library card. The rhombic grid structure can provide support in multiple directions, enabling the library card to maintain good stability under the action of bending forces in different directions. When the library card is subjected to an external force, the rhombic grid can disperse the stress to multiple rhombic units, thereby reducing the risk of local stress concentration and improving the overall durability. The library card body 1 has good bending resistance performance, is not easily broken or damaged during use, has a long service life, does not require frequent replacement, and reduces the economic pressure on students.

[0040] Furthermore, both the first bending portion 301 and the second bending portion 302 are strip-shaped.

[0041] Specifically, the strip-shaped bending portion can provide uniform supporting force along its length direction. The strip structure is relatively simple and can be easily manufactured by processes such as stamping, cutting, or injection molding. This manufacturing method not only has a lower cost but also a high production efficiency, which is beneficial to large-scale production. The strip-shaped bending portion can be flexibly arranged according to the actual size and design requirements of the library card. Whether it is inclined and distributed along the diagonal or in any other direction, a good supporting effect can be achieved.

[0042] Furthermore, both the first bending portion 301 and the second bending portion 302 are square strip-shaped structures that are solid or hollow.

[0043] Specifically, the solid square strip-shaped bending portion has high rigidity and strength and can more effectively resist bending and twisting. Due to the uniform distribution of materials, its supporting force in all directions is relatively consistent, which is suitable for scenarios with high requirements for bending resistance performance.

[0044] While maintaining a certain rigidity and strength, the hollow square strip-shaped bending portion reduces the cost and weight by reducing the material usage. Compared with the solid structure, the hollow structure significantly reduces the amount of material used, which helps to reduce the manufacturing cost and the weight of the library card. The square strip shape means that its cross-section is a rectangular structure. In order to avoid a large thickness of the library card body 1, the thickness of the bending portion should not be too large.

[0045] Furthermore, the RFID tag 4 is adhered to the bottom plate 102 by double-sided tape.

[0046] Furthermore, after the bottom plate 102 and the panel 101 are closed and adhered, the anti-bending component 3 and the RFID tag 4 are sealed inside the library card body 1.

[0047] Furthermore, a fixing ring 2 is adhesively bonded to the circumference of the library card body 1, and the top surface and the bottom surface of the fixing ring 2 are both located outside the library card body 1.

[0048] Specifically, the bottom plate 102 and the panel 101 are the main components of the library card body 1. They are tightly bonded together through a specific adhesive or hot melt technology. During the bonding process, it is necessary to ensure the alignment and flatness of the bottom plate 102 and the panel 101 to avoid misalignment or unevenness. When the bottom plate 102 and the panel 101 are completely bonded, a closed space is formed between them. This space contains the anti-bending component 3 and the RFID tag 4. This sealing effect effectively prevents external substances such as moisture and dust from entering the library card body 1, thereby protecting the integrity and functionality of the internal components. During the bonding process of the bottom plate 102 and the panel 101, the anti-bending component 3 is firmly fixed inside the library card body 1, providing both the necessary support force and maintaining the overall stability. Before the bottom plate 102 and the panel 101 are bonded, the RFID tag 4 is precisely placed at the designated position of the library card body 1. With the completion of the bonding of the bottom plate 102 and the panel 101, the RFID tag 4 is also sealed inside the library card body 1, thus avoiding damage caused by external factors. To further enhance the structural strength and durability of the library card body 1, a fixing ring 2 can be adhesively fixed around its circumference. The top and bottom surfaces of the fixing ring 2 are both located outside the library card body 1. The bonding between the fixing ring 2 and the library card body 1 should be firm and reliable to ensure that it will not loosen or fall off during long-term use.

[0049] Embodiment 5

[0050] Furthermore, the top surface of the panel 101 is a downwardly concave curved surface 1011, and patterns and characters are printed on the curved surface 1011.

[0051] Specifically, the top surface of the panel 101 is a slightly downwardly concave curved surface 1011. Patterns and characters related to the school are printed on this curved surface 1011, and a wear-resistant and scratch-resistant coating is applied. The design of the library card with a curved surface 1011 on the top surface can appropriately reduce the contact area with objects during long-term use compared to a library card with a flat top surface. In this way, the patterns and characters on the top surface of the library card are not easily worn off.

[0052] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Based on the technical essence of the present invention, any simple modifications, equivalent replacements, and improvements made to the above embodiments within the spirit and principles of the present invention still fall within the protection scope of the technical solution of the present invention.
