[0002] An electronic student ID card is an intelligent card integrating high-tech functions. It not only contains traditional student ID card information, such as the student's photo, name, age, and enrollment time, but also has advanced chips built in. These chips enable the electronic student ID card to store more personal information and data. In addition, it is equipped with a GPS positioning system module, and this function can be used to locate the student's position in real time, enhancing campus security and the efficiency of student management. Through this technology, schools can more effectively monitor students' attendance, and at the same time provide a means for parents to understand their children's situation at school.

[0003] After a large number of searches, the publication number is CN115115012A, which discloses an intelligent electronic student ID card. When installing the connecting belt, the inner hexagon stud can drive the plug to move, so as to squeeze the airbag body, and then the airbag body squeezes the slider and the needle seat to move downward, and the fixed thorn needle is inserted into the connecting belt, which can relatively fix the connecting belt after installation, avoid the relative friction between the connecting belt and the mounting post during use, and cause the connecting belt to wear and break, extend the service life, and by adopting the method of matching the inner hexagon stud with the mounting post for installation, the installation difficulty can be greatly reduced, and the installation and replacement efficiency of the connecting belt can be improved.

[0004] During actual use, it is necessary to puncture the connecting belt with the fixed thorn needle to achieve the positioning of the connecting belt. However, when the puncture position of the fixed thorn needle on the connecting belt is pulled by a large external force, the puncture position on the connecting belt will be deformed due to the pulling, and in severe cases, the internal fibers of the connecting belt will break, thus affecting the quality and service life of the connecting belt. For this reason, an intelligent electronic student ID card is needed to solve the above problems. Content of the Utility Model

The distance between the two ends inside the adjusting frame matches the thickness of the protection mechanism. Second reserved holes are respectively opened on both sides of the front and back sides of the adjusting frame, and first reserved holes are respectively opened on the tops of the front and back sides of the adjusting frame.

[0015] The adjusting frame uses transparent acrylic material, providing good transparency and durability. The fixed connection between the inner top of the adjusting frame and the limiting block ensures the stability of the protection structure. At the same time, the size of the adjusting frame matches the thickness of the protection mechanism, ensuring the overall compactness and coordination.

[0016] Preferably, an installation screw is movably inserted into the second reserved hole, and the installation screw in the second reserved hole passes through the second reserved hole and is threadedly installed in the second installation screw hole.

[0017] The opening of the second reserved hole enables the installation screw to accurately position and fix the protective shell. This precise positioning design not only improves the assembly efficiency but also ensures the stability and durability of the electronic certificate during use.

[0018] Preferably, an installation screw is movably inserted into the first reserved hole, and the installation screw in the first reserved hole passes through the first reserved hole and is threadedly installed in the first installation screw hole.

[0040] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0041] Embodiment

[0042] As Figures 1 to 7 shown, an embodiment provided by the present utility model: An intelligent electronic student ID card includes an electronic certificate 1, and a protection mechanism 3 is sleeved outside the electronic certificate 1. The protection mechanism 3 includes a first protective shell 31 and a second protective shell 32. The first protective shell 31 and the second protective shell 32 are closed and installed through an adjustment frame 2. Openings 305 are provided at the tops of the opposite sides of the first protective shell 31 and the second protective shell 32;

[0043] Connecting rods 304 are respectively fixedly installed at the tops of the first protective shell 31 and the second protective shell 32 on the opposite sides of the two openings 305 facing away from each other. The opposite ends of the two connecting rods 304 are in contact but not fixedly connected;

[0044] A hanging strap 4 is movably sleeved on the top of the protection mechanism 3 through the two connecting rods 304;

[0045] A limit block 101 is movably installed in the middle of the top of the electronic certificate 1. The limit block 101 passes through from the opposite sides of the two openings 305. First installation screw holes 104 are provided on both the front and back sides of the limit block 101, and a limit groove 102 is provided on the upper end surface of the limit block 101.

[0046] When in use, the protection mechanism 3 outside the electronic certificate 1 is composed of a first protective shell 31 and a second protective shell 32, and they are closed and installed through an adjustment frame 2, ensuring the safety and stability of the electronic certificate 1. This design not only provides physical protection but also provides a fixed installation point for the hanging strap 4;

[0047] The two connecting rods 304 at the top of the protection mechanism 3 are movably sleeved on the hanging belt 4. This structure allows the hanging belt 4 to move within a certain range but will not slide excessively. The design of the connecting rods 304 sleeving the hanging belt 4 makes the connection between the hanging belt 4 and the electronic certificate 1 more convenient and fast;

[0048] The limiting block 101 at the top of the electronic certificate 1 passes through from the opposite side of the two openings 305. Installation screw holes are provided on both the front and back sides, and a limiting groove 102 is also provided on the upper end surface. Such a design enables the limiting block 101 to rise and fall with the adjusting frame 2. At the same time, the anti-slip lines on the inner wall of the limiting groove 102 increase the friction between the hanging belt 4 and the limiting block 101, ensuring that the hanging belt 4 does not easily slide during use after the adjusting frame 2 is positioned;

[0049] The limiting block 101 is made of soft rubber material and is combined with the connecting spring 103, which provides convenience for the installation of the hanging belt 4. When the adjusting frame 2 is not positioned, the limiting block 101 moves away from the connecting rod 304 under the action of the connecting spring 103, facilitating the installation of the hanging belt 4. The anti-slip line design on the inner wall of the limiting groove 102 further improves the stability of the hanging belt 4 and avoids the sliding and wear of the hanging belt 4 during use.

[0050] Through the above design, the intelligent electronic student ID not only solves the problem of positioning the hanging belt 4, but also improves the durability of the hanging belt 4 and the user experience. These advantages make the intelligent electronic student ID more reliable and comfortable in actual use, and at the same time reduce the risk of equipment damage caused by problems with the hanging belt 4.

[0051] For the convenience of using the electronic certificate, by way of example, as Figures 4 to 6 shown, the present utility model further includes that the electronic certificate 1 further includes induction areas 11. There are two induction areas 11, and the two induction areas 11 are respectively arranged on the front and back sides of the electronic certificate 1. The electronic certificate 1 is internally provided with an NFC module.

[0052] When in use, there is an induction area 11 on each of the front and back sides of the electronic certificate 1. This layout enables convenient NFC data exchange and identity verification regardless of how the electronic certificate 1 is placed. The built-in NFC module provides a fast and secure communication method and can be used for various applications on campus. Students can unlock dormitory doors, library doors, or other areas that require identity verification by swiping their electronic student ID cards, improving security and convenience. In the library, the NFC function of the student ID card can be used to borrow books without the need for a traditional library card, simplifying the borrowing process. In consumption places such as campus stores and cafeterias, students can make quick payments through their electronic student ID cards without carrying cash or using other payment tools. Through NFC technology, students' attendance can be automatically recorded when entering or leaving classrooms or the campus, improving the accuracy and efficiency of attendance. The electronic student ID card can be associated with the student's electronic wallet account to store electronic currency, facilitating various transactions on campus. The student ID card can also be used for interaction with other NFC devices, such as querying campus announcements, exam scores, etc. at information kiosks.

[0053] For the convenience of protecting the electronic certificate through the protection mechanism, by way of example, as Figure 3 shown, the present utility model further includes that the first protective shell 31 and the second protective shell 32 are of matching sizes and are mirror-distributed. Cavities 302 are provided on the inner sides of the first protective shell 31 and the second protective shell 32. Reserved slots 303 are provided in the middle of the front and back sides of the first protective shell 31 and the second protective shell 32. Second mounting screw holes 301 are provided on the back sides of the front and back sides of the first protective shell 31 and the second protective shell 32 and are directed away from each other.

[0054] When in use, the first protective shell 31 and the second protective shell 32 adopt a mirror-symmetrical layout. This design ensures the balance of the overall structure. This symmetry not only gives a sense of beauty visually but also provides stability structurally, making the student ID card more durable;

[0055] The presence of the cavities 302 provides necessary space for the internal circuit board and NFC module. Such a design takes into account the safety of electronic components when subjected to impacts. The design of the cavities 302 plays a buffering role, which can absorb and disperse external impact forces, thereby protecting the sensitive internal electronic components and extending the service life of the student ID card;

[0056] The design of the reserved slots 303 provides sufficient space for the induction area 11, ensuring the efficiency and accuracy of the NFC module during data exchange. Such a design avoids possible occlusion problems during card swiping or wireless communication, ensuring smooth communication regardless of how the student ID card is placed.

[0057] For positioning and installing the protection mechanism 3 to improve the stability of the overall structure, by way of example, as Figure 1, Figure 2 and Figure 7 As shown in and

[0058] , the utility model further includes that the adjusting frame 2 is designed with transparent acrylic material. The front and rear ends of the inner top of the adjusting frame 2 are respectively fixedly connected with the front and rear ends of the limiting block 101. The distance between the two ends inside the adjusting frame 2 matches the thickness of the protection mechanism 3. Second reserved holes 22 are respectively opened on both sides of the front and back sides of the adjusting frame 2, and first reserved holes 21 are respectively opened on the tops of the front and back sides of the adjusting frame 2.

[0058] When in use, the adjusting frame 2 made of transparent acrylic material provides good transparency and durability. The fixed connection between the inner top of the adjusting frame 2 and the limiting block 101 ensures the stability of the protection structure. At the same time, the size of the adjusting frame 2 matches the thickness of the protection mechanism 3, ensuring the overall compactness and coordination.

[0059] Mounting screws 201 are movably inserted into the second reserved holes 22. The mounting screws 201 in the second reserved holes 22 pass through the second reserved holes 22 and are threadedly mounted in the second mounting screw holes 301.

[0060] When in use, the opening of the second reserved holes 22 enables the mounting screws 201 to accurately position and fix the protective shell. This precise positioning design not only improves the assembly efficiency but also ensures the stability and durability of the electronic certificate 1 during use.

[0061] Mounting screws 201 are movably inserted into the first reserved holes 21. The mounting screws 201 in the first reserved holes 21 pass through the first reserved holes 21 and are threadedly mounted in the first mounting screw holes 104.

[0062] When in use, the opening of the first reserved holes 21 enables the mounting screws 201 to accurately position and fix the limiting block 101. This precise positioning design not only improves the assembly efficiency but also ensures the stability and durability of the electronic certificate 1 during use.

[0063] Through the first reserved hole 21 and the second reserved hole 22, the mounting screw 201 can accurately position the limiting block 101 and the protective shell, ensuring that each component is installed in a predetermined position. This precise positioning helps to maintain the overall structure and function accuracy of the electronic certificate 1. The precise reserved holes enable the mounting screw 201 to be quickly and easily installed in place, thereby improving the efficiency of the assembly process. This design reduces the adjustments and errors during assembly, ensuring the smooth operation of the production line and the convenience of assembly workers. The precise fixation of the limiting block 101 and the protective shell helps to improve the stability of the electronic certificate 1 during use. This stability is crucial for ensuring the normal operation of the internal components of the electronic certificate and preventing accidental damage. Precise assembly and fixation reduce the stress and wear on the electronic certificate 1 during use, thereby extending the service life of the product. This is very important for improving the durability of the product and reducing long-term maintenance costs. When maintenance or component replacement of the electronic certificate 1 is required, the precise reserved hole design makes disassembly and reassembly simple and quick, reducing maintenance time and costs.

[0064] In order to prevent the hanging strap from sliding easily after installation, thereby protecting the hanging strap and extending its service life, exemplarily, as Figure 1 and Figure 6 shown, the present utility model further includes that the bottom of the inner side of the hanging strap 4 contacts the outer wall of the bottom of the two connecting rods 304, and the bottom of the outer side of the hanging strap 4 contacts the inner wall of the limiting groove 102.

[0065] During use, the ingenious combination of the hanging strap 4 with the connecting rod 304 and the limiting groove 102 ensures the stability of the hanging strap 4 and the wearing comfort of the user. The contact between the bottom of the inner side of the hanging strap 4 and the outer wall of the bottom of the connecting rod 304, as well as the contact between the bottom of the outer side of the hanging strap 4 and the inner wall of the limiting groove 102, form a stable limiting structure, thereby preventing the hanging strap 4 from moving back and forth and causing a large degree of wear.

[0066] The limiting block 101 is designed with a soft rubber material. A connecting spring 103 is elastically installed at the bottom of the limiting block 101, and the bottom of the connecting spring 103 is elastically connected to the middle of the top of the electronic certificate 1. The connecting spring 103 is designed with a tension spring material.

[0067] During use, the limiting block 101 made of soft rubber material, in cooperation with the connecting spring 103, provides convenience for the installation of the hanging strap 4 on the electronic certificate 1. When the adjusting frame 2 is not positioned, the limiting block 101 moves away from the connecting rod 304 under the action of the connecting spring 103, thus facilitating the installation of the hanging strap 4

[0068] Anti-slip lines parallel to the two connecting rods 304 are provided on the inner wall of the limiting groove 102, and the depth dimension of the limiting groove 102 is the radius dimension of the connecting rod 304.

[0069] When in use, the anti-slip pattern design on the inner wall of the limiting groove 102 increases the friction between the strap 4 and the limiting block 101, ensuring that the strap 4 is not easy to slide during use, improving the stability and safety of the electronic certificate 1, and avoiding wear on the connection of the strap 4 during use.

[0070] When the utility model is used, the first protective shell 31 and the second protective shell 32 are arranged in a mirror image, and the electronic certificate 1 is placed in the cavity 302 in the first protective shell 31 and the second protective shell 32. At this time, the first protective shell 31 and the second protective shell 32 are pushed at the same time and moved to the opposite side. At this time, under the action of the connecting spring 103, the limit block 101 is not in contact with the connecting rod 304. At this time, the hanging belt 4 can be passed between the two connecting rods 304. After the first protective shell 31 and the second protective shell 32 are spliced, the limit block 101 is located in the opening 305 at the top of the first protective shell 31 and the second protective shell 32;

[0071] At this time, the adjusting frame 2 can be pushed upward on the outside of the first protective shell 31 and the second protective shell 32, so that the first reserved hole 21 is aligned with the first mounting screw hole 104, and the second reserved hole 22 is aligned with the second mounting screw hole 301, and then the adjusting frame 2 is fixedly installed on the outside of the first protective shell 31 and the second protective shell 32 by installing the screw 201. At the same time, the first protective shell 31 and the second protective shell 32 can be fixedly connected with each other with the help of the adjusting frame 2. After the adjusting frame 2 is fixedly installed, the limit block 101 can be moved upward in the opening 305, and the limit groove 102 on the limit block 101 is used to limit the hanging belt 4 passing through the connecting rod 304, so that when it is used, the wear caused by the back and forth movement of the hanging belt 4 is avoided. At the same time, after the hanging belt 4 is limited, it will not cause damage to the hanging belt 4 itself, thereby extending the service life.
