[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-4A wireless charging folding card holder includes a first support plate 1, a second support plate 2, a cover plate 3, a mounting plate 4, a first magnetic block 5, a control module 18, a charging coil module 6, a charging port 7, and a card fixing mechanism. The upper left side of the second support plate 2 is hinged to the upper right side of the first support plate 1. The front side of the second support plate 2 has an opening with a card holder slot, through which a card can be placed. The cover plate 3 is located on the left side of the first support plate 1. The mounting plate 4 is connected to the right side of the first support plate 1. The first magnetic blocks 5 are evenly spaced around the upper left side of the mounting plate 4. The charging coil module 6 is connected to the upper left side of the mounting plate 4 and is located between the magnetic blocks. The charging port 7 is connected to the lower left side of the mounting plate 4 and is located on one side of the first support plate 1. The charging port 7 and the charging coil module 6 are electrically connected to the control module 18. When the user needs to charge the device, an external power source (such as a power adapter) is connected through the charging port 7. The external power source provides power to the entire wireless charging assembly. The electrical energy is first transmitted to the control module 18. The control module 18 is like the control center of the entire wireless charging assembly. It is responsible for managing and distributing electrical energy and coordinating the operation of the charging coil module 6. The control module 18 is existing technology and will not be described in detail here.

[0026] The following is a standard control method for control module 18: Control module 18 performs preliminary processing on the input electrical energy, such as converting AC to DC (if the external power source is AC), and monitors parameters such as input voltage and current to ensure they are within safe and appropriate ranges. Control module 18 then transmits the processed electrical energy to charging coil module 6. Charging coil module 6 contains one or more coils that generate an alternating magnetic field when energized. According to the principle of electromagnetic induction, when an alternating current passes through the charging coil, an alternating magnetic field is generated around it. This alternating magnetic field radiates energy outward. When a device supporting wireless charging (such as a mobile phone, which has a corresponding wireless charging receiver module) approaches the wireless charging component, the receiving coil inside the device is placed in this alternating magnetic field. Due to electromagnetic induction, an induced electromotive force is generated in the receiving coil. This induced electromotive force forms an induced current in the internal circuitry of the device. The internal circuitry of the device processes this induced current, converting it into a current and voltage suitable for charging the device's battery. This process may include rectification, filtering, and voltage regulation to ensure stable and safe charging of the battery.

[0027] To facilitate temporary charging for users, the first support plate 11 is also equipped with a rechargeable battery module, which includes components connected to the control module 18. Figure 3The lithium battery and charging switch (both are not shown in the figure because they are located inside the first support plate 11) are connected by the control module 18 (which is shown in dashed lines because it is located inside the first support plate 11). The lithium battery is located inside the first support plate 11, and the charging switch is located on one side or inside the first support plate 11, which can be determined according to the actual situation to realize the charging on or off.

[0028] The following is an example of a rechargeable battery module in the prior art: In the initial state, the charging switch is in the off position. Even if the lithium battery in the rechargeable battery module has charge, no current will be output to power other components, and external power cannot charge the lithium battery through this switch. The entire wireless charging assembly is in the off state, and each module remains in standby, waiting for the charging switch to trigger and change its state. An external power source is connected to the wireless charging assembly through charging port 7 to charge the lithium battery in the rechargeable battery module. For example, the electrical energy input from the external power source is first processed by the control module 18, such as adjusting parameters like voltage and current to meet the safety requirements for lithium battery charging (e.g., controlling the charging voltage within the appropriate charging voltage range for the lithium battery, limiting the charging current to prevent excessive damage to the battery). Afterward, the processed electrical energy is transmitted to the lithium battery through the connection line to begin charging. During the charging process, the control module 18 continuously monitors various charging parameters of the lithium battery, such as battery voltage, charging current, and battery temperature. Furthermore, when the user manually triggers the charging switch to the on state, the control module 18 detects the on signal from the charging switch. At this time, the lithium battery in the charging battery module can act as a power source to power the wireless charging component. The DC power output from the lithium battery is transmitted to the control module 18, which performs power conversion and distribution operations according to the current working needs of the wireless charging component. For example, if the charging coil module 66 requires AC power to generate an alternating magnetic field to achieve the wireless charging function, the control module 18 converts the DC power into AC power of appropriate frequency and voltage and sends it to the charging coil module 6, so that the wireless charging component can continue to maintain wireless charging operation by relying on the power stored in the lithium battery.

[0029] Specifically, such as Figure 3 As shown, the first support plate 1 is provided with a first magnetic block 5 and a second magnetic block 17. The first magnetic block 5 is arranged around the charging coil module 6. The mobile phone can be magnetically fixed to the upper part of the device through the first magnetic block 5. However, there is still a possibility that the device and the mobile phone may be offset relative to each other. Therefore, this application sets the second magnetic block 17 below the first magnetic block 5, so that the lower part of the mobile phone can be fixed by the second magnetic block 17. The mobile phone is attracted by the second magnetic block 17, so that the upper and lower parts of the device are attached to the mobile phone, thereby avoiding the mobile phone being offset from the upper or lower part of the device, which would affect normal use.

[0030] Reference Figure 4 To prevent bank cards or business cards from falling out of the card holder slot and being lost, this device further includes a card fixing mechanism comprising a first magnetic strip 8 and a first iron strip 9. The first magnetic strip 8 is connected to both the upper and lower sides of the opening of the first support plate 11, and the first iron strip 9 is also connected to both the upper and lower sides of the opening of the first support plate 11. The first magnetic strip 8 is attracted to the first iron strip 9. When a card is placed in the card holder slot, the first magnetic strip 8 and the first iron strip 9 work together to close the opening of the card holder slot, thus limiting and preventing the card from being placed securely and stably within the card holder slot, preventing loss.

[0031] Reference Figure 5 and Figure 6 To address the limitation of existing technologies in terms of angle adjustment, this application further includes an adjustment plate 11 and a magnetic slider 13. A receiving groove 10 is formed on the right side of the housing, and the adjustment plate 11 is hinged to the top of the receiving groove 10. When the first support plate 1 and the second support plate 2 are unfolded, one end of the adjustment plate 11, connected to the magnetic slider 13, is pulled out of the receiving groove 10 during the unfolding process. Conversely, when the first support plate 1 and the second support plate 2 are retracted, the adjustment plate 11 moves back into the receiving groove 10. A sliding groove 12 is formed on the left side of the second support plate 2, and the sliding groove 12... A magnetic slider 13 is slidably connected, and a magnetic plate is provided inside the second support plate 2. The magnetic plate is made of iron. The magnetic slider 13 is attracted to the left side of the second support plate 2 through the magnetic plate. The right side of the adjustment plate 11 and the left side of the magnetic slider 13 are hinged. The magnetic slider 13 is slidably disposed in the slide groove 12 and slides up and down along the direction of the slide groove 12. The process of the adjustment plate 11 sliding on the slide groove 12 through the magnetic slider 13 is equivalent to controlling the opening and closing angle between the first support plate 1 and the second support, so that the angle of the mobile phone stand can be adjusted when the device is used as a mobile phone stand.

[0032] The aforementioned angle adjustment component can be used between the second support plate 2 and the third support plate 14 or between the third support plate 14 and the fourth support plate, depending on actual needs.

[0033] Reference Figure 1 It also includes a third support plate 14, with the upper right side of the second support plate 2 and the upper left side of the third support plate 14 hinged together. The front side of the third support plate 14 has an opening with a card slot, through which cards can be placed into the third support plate 14.

[0034] Reference Figure 7It also includes a second magnetic strip 15 and a second iron strip 16. The second magnetic strip 15 is connected to both the upper and lower sides of the opening of the third support plate 14, and the second iron strip 16 is connected to both the upper and lower sides of the opening of the third support plate 14. The second magnetic strip 15 is attracted to the second iron strip 16.

[0035] People pull the first magnetic stripe 8, pulling it out of the card slot of the second support plate 2. The first magnetic stripe 8 separates from the first iron strip 9. Then, a card is placed into the second support plate 2, and the first magnetic stripe 8 is put back into the second support plate 2. The first magnetic stripe 8 blocks the cards in the second support plate 2, preventing them from being lost. The first magnetic stripe 8 is also attached to the first iron strip 9, preventing it from moving out of the second support plate 2. The third support plate 14 can also store cards, allowing for more cards to be carried and increasing its practicality. The second magnetic stripe 15 blocks the cards in the third support plate 14, preventing them from being lost. The second magnetic stripe 15 is attached to the second iron strip 16, preventing the second magnetic stripe 9 from moving out of the second support plate 14. The suction strip 15 moves out from the third support plate 14. After the first support plate 1 and the second support plate 2 are unfolded, they can be used as a mobile phone stand. The adjustment plate 11 rotates, and the magnetic slider 13 slides in the slide groove 12, thereby adjusting the angle of the first support plate 1. People can adjust the best viewing angle according to their own eye level and comfort to accommodate different people. The magnetic slider 13 can be attached to the left side of the first support plate 1, thereby preventing the first support plate 1 and the second support plate 2 from separating and changing the angle between the first support plate 1 and the second support plate 2. People can place their mobile phone against the cover plate 3, and the magnetic block can hold the mobile phone in place to prevent it from falling over. The charging port 7 is connected to an external power source, so that the charging coil module 6 can charge the mobile phone, making it more convenient to use.
