Description

Technical Field

[0001] This utility model relates to the field of wireless charging technology, specifically a coiled wireless charger. Background Technology

[0002] Wireless charging is a charging method or device that eliminates the need for traditional charging cables and instead uses technologies such as electromagnetic induction and magnetic resonance to transfer energy. Its core principle is that a transmitting coil generates an alternating electromagnetic field, which is then converted into electrical energy by the receiving coil, thus charging electronic devices (such as mobile phones and headphones).

[0003] With the increasing prevalence of wireless charging technology, traditional wireless chargers often face the problem of inconvenient cable storage. In existing products, wireless chargers and charging cables are mostly separate accessories, leading to issues like tangled cables and loss during transport, impacting user experience and reducing product portability. Furthermore, some devices with integrated storage functions have complex structural designs, occupying significant storage space, or suffer from insufficient stability due to unreasonable storage structure and charging module layout. This situation is exacerbated by users' growing demand for "integrated" and "easy-to-use" portable electronic devices.

[0004] To address this issue, we propose a coiled wireless charger. Summary of the Invention

[0005] The purpose of this invention is to provide a retractable wireless charger that solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coiled wireless charger, comprising: The wireless charging module, including a decorative film, a wireless charging cover, and a wireless charging PCBA, is used to power devices that support wireless charging. The base assembly includes a wireless charging base with a cable management tray at the bottom for storing the charging cable; An anti-slip silicone pad is placed on the bottom of the wireless charging base to prevent the device from slipping when placed on it.

[0007] Preferably, the charging cable is 1m long and can be wound into the storage tray at the bottom of the wireless charging base when stored, and can be taken out from the storage tray when in use.

[0008] Preferably, the wireless charging PCBA integrates a wireless charging control circuit, which can be adapted to devices that support wireless charging, such as mobile phones, headphones, and watches.

[0009] Preferably, the anti-slip silicone pad covers the outer periphery of the storage tray at the bottom of the wireless charging base to ensure the stability of the device when placed.

[0010] Preferably, the wireless charging top cover is fastened to the wireless charging base, forming an internal space to accommodate the wireless charging PCBA, and a decorative film is disposed on the surface of the wireless charging top cover.

[0011] This invention provides a retractable wireless charger. The retractable wireless charger has the following advantages: This retractable wireless charger integrates the traditional separate wireless charger and charging cable, solving the cable storage problem with the base storage tray, reducing the number of accessories when portable, and improving practicality.

[0014] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0015] like Figure 1-2 As shown, this utility model provides a technical solution: a coiled wireless charger, comprising: The wireless charging module includes a decorative film 1, a wireless charging top cover 2, and a wireless charging PCBA 3, which is used to power devices that support wireless charging. The wireless charging PCBA 3 integrates a wireless charging control circuit and can be adapted to devices that support wireless charging, such as mobile phones, headphones, and watches. The wireless charging top cover 2 is fastened to the wireless charging base 4, forming a space inside to accommodate the wireless charging PCBA 3. The decorative film 1 is set on the surface of the wireless charging top cover 2. The base assembly includes a wireless charging base 4, which has a cable storage tray at the bottom for storing the charging cable 6. The charging cable 6 is 1m long and can be wound into the storage tray at the bottom of the wireless charging base 4 when stored and can be taken out from the storage tray when in use. An anti-slip silicone pad 5 is placed at the bottom of the wireless charging base 4 to prevent the device from slipping when placed. The anti-slip silicone pad 5 covers the outer perimeter of the storage tray at the bottom of the wireless charging base 4 to ensure the stability of the device when placed.

[0016] Working principle: When this wireless charger with cable retractable design is in operation, an external power source is connected through a 1-meter-long charging cable 6. The charging cable 6 can be stored in the cable retractable tray at the bottom of the wireless charging base 4. When in use, it is taken out and connected to a power source, and electrical energy is input to the wireless charging PCBA3. Its integrated wireless charging control circuit uses the principle of electromagnetic induction to enable wireless charging-enabled devices such as mobile phones and earphones placed on the surface of the wireless charging cover 2 to be charged by receiving the electromagnetic field induced by the receiving coil. The wireless charging cover 2 and the base are fastened together to protect the internal circuit. The decorative film covering the cover serves an aesthetic purpose. The anti-slip silicone pad 5 at the bottom of the base covers the outer perimeter of the retractable tray to ensure that the device is stable and does not slide when placed. The whole device combines charging function and portability through the integration of wireless charging module and cable storage structure.
