[0002] With the widespread use of portable electronic products such as mobile phones, the application of batteries is becoming increasingly common, and wireless charging technology is gradually emerging. However, although wireless chargers use electromagnetic induction for charging, they still require a power cable to connect to the wireless charger for power. Current wireless chargers typically have fixed-length power cables, requiring users to ensure the distance between the wireless charger and the socket does not exceed the length of the power cable during charging, limiting user flexibility. Secondly, the power cables of these wireless chargers are usually exposed, making them susceptible to pulling, bending, and other external forces, which may lead to cable breakage and poor contact after prolonged use, affecting the charger's lifespan and charging efficiency. Furthermore, they are prone to tangling with other items during storage, resulting in generally lower convenience, economy, and practicality. Utility Model Content

[0003] To address the problems mentioned above, this utility model provides a wireless charger with a retractable cable. The length of the power cord can be adjusted to improve flexibility of use.

[0005] Furthermore, the housing includes an upper shell and a lower shell, which are interlocked and connected internally to form a contraction space. The rotating disk is rotatably installed in the contraction space, and the side walls of the upper and lower shells are connected to form an opening for storing and retrieving connecting wires.

[0006] Furthermore, a connecting column is provided at the center of the upper shell, which is vertically inserted into the contraction space, and the rotating disk is rotatably inserted into the connecting column.

[0007] Furthermore, the rotating disk surface is provided with a winding boss, the connecting wire is wound around the winding boss, the surface of the winding boss is sunken to form an installation groove, and the winding mechanism is engaged in the installation groove.

[0008] Furthermore, the winding mechanism includes a spring installed in the mounting groove and a track cover plate covering the surface of the mounting groove. The surface of the track cover plate is provided with a sliding track, and a stop spring piece is installed on the surface of the lower shell, which is fitted into the sliding track and moves along the sliding track.

[0009] Furthermore, the lower shell surface is provided with a movable groove, the stop spring is movably installed in the movable groove, and the surface of the stop spring is provided with a sliding block that is slidably fitted into the sliding track.

[0024] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1 to 3As shown, a wireless charger with a retractable cable allows for adjustment of the power cord length, improving usability. When not in use, the power cord can be coiled up to prevent damage and tangling during storage, enhancing convenience. This embodiment of the wireless charger includes a housing 1, a rotating disk 2 rotatably mounted within the housing 1, and a wireless charging mechanism 3 mounted on the surface of the housing 1. The rotating disk 2 has a connecting cable 4 wound around it for connecting to a power source. The wireless charging mechanism 3 is electrically connected to the connecting cable 4, allowing electronic devices to be directly placed on the wireless charging mechanism 3 on the surface of the housing 1 for wireless charging, providing a convenient charging method. Furthermore, during charging, the rotating disk 2 can rotate to coil or unwind the connecting cable 4, adjusting its length and improving usability. After charging is complete, the rotating disk 2 can coil the connecting cable 4, preventing exposed wear and tear that could affect its lifespan and avoiding tangling that could complicate use and portability.

[0026] like Figures 1 to 3 As shown, the housing 1 in this embodiment includes an upper shell 11 and a lower shell 12. The upper shell 11 and the lower shell 12 are interlocked and connected internally to form a shrinkage space. A connecting post 111 is provided at the center of the upper shell 11, which is vertically inserted into the shrinkage space. The rotating disk 2 is rotatably inserted into the connecting post 111. When the rotating disk 2 rotates around the connecting post 111, the connecting wire 4 can be wound up and stored in the shrinkage space under the action of the rotating disk 2, thereby avoiding the connecting wire 4 from being exposed and causing wear. Furthermore, in order to facilitate the stretching and shrinking of the connecting wire 4, an opening 13 is provided on the side wall after the upper shell 11 and the lower shell 12 are interlocked. The end of the connecting wire 4 that is connected to the power supply can be exposed to the outside of the housing 1 through the opening 13, thereby making it convenient for the user to pull out the connecting wire 4 wound up in the shrinkage space for use.

[0027] like Figure 3 and Figure 4As shown, in order to achieve the rotation of the rotating disk 2, a winding mechanism 5 is installed on the rotating disk 2 in this embodiment. When the connecting wire 4 is stretched, it can store force in the winding mechanism. When the connecting wire 4 is wound up, the stored force can be released by the winding mechanism 5 to make the rotating disk 2 rotate and thus wind up the connecting wire 4. The winding method is convenient. In addition, the rotating disk 2 in this embodiment has a winding boss 21 on the surface facing the lower shell 12. When the connecting wire 4 is wound up under the drive of the rotating disk 2, it can follow the rotation of the rotating disk 2 and wrap around the winding boss 21, making the winding of the connecting wire 4 simpler and easier to unwind. Meanwhile, in this embodiment, the surface of the winding boss 21 is recessed to form an installation groove 22. The winding mechanism 5 is located in the installation groove 22 and is engaged with the connecting post 111. When the connecting wire 4 is stretched, thereby driving the rotating disk 2 to rotate, the winding mechanism 5 stores force due to being engaged with the connecting post 111. When the connecting wire 4 is finished and needs to be wound up, the power stored by the winding mechanism 5 during the stretching of the connecting wire 4 can drive the rotating disk 2 to rotate in the opposite direction, thereby winding the connecting wire 4 onto the winding boss 21 to complete the winding.

[0028] Specifically, such as Figure 3 and Figure 4 As shown, the winding mechanism 5 of this embodiment includes a spring 51 installed in the mounting groove 22 and a track cover plate 52 covering the surface of the mounting groove 22. The center end of the spring 51 is engaged with the connecting post 111, and the edge end of the spring 51 is engaged with the edge of the winding boss 21. When the user pulls the connecting line 4 to rotate the rotating disk 2, the spring 51 installed in the mounting groove 22 can be tightened and stored under the action of the rotating disk 2, so as to retract the connecting line 4 when the rotating disk 2 is driven to rotate in the future. It is convenient to use.

[0029] Furthermore, in order to allow users to pull out the connecting wire 4 to a suitable length as needed and fix the pulled-out length to prevent the connecting wire 4 from automatically winding up during use, this embodiment provides a sliding track 521 on the surface of the track cover plate 52, and a stop spring 7 is provided on the inner surface of the lower shell 12, which is fitted into the sliding track 521 to lock the rotation of the rotating disk 2. When the user pulls out the connecting wire 4 to the corresponding length as needed, the stop spring 7 can move along the sliding track 521. After being released, the stop spring 7 is locked in the locking position of the sliding track 521, thereby locking the rotating disk 2, so that the length of the pulled-out connecting wire 4 can be used freely.

[0030] Specifically, in this embodiment, the lower shell 12 has a movable groove on its surface, the stop spring 7 is movably installed in the movable groove, and the surface of the stop spring 7 has a sliding block 71 that is slidably fitted into the sliding rail 521. When the user pulls the connecting line 4 to drive the rotating disk 2 to rotate, the sliding block 71 on the stop spring 7 can move along the sliding rail 521 and follow the sliding rail 521 to make the stop spring 7 slide in the movable groove to realize the normal stretching of the connecting line 4.

[0031] like Figure 4 As shown, the sliding track 521 of this embodiment includes a track groove formed on the surface of the track cover plate 52, and a guide bar is provided in the track groove surrounding the rotation center of the rotating disk 2. In this embodiment, two guide bars are provided, and the two guide bars are combined to form two interlocking annular tracks in the track groove. One end of one of the guide bars in this embodiment is provided with a stop opening. When the user stretches the connecting line 4 to make the rotating disk 2 rotate, the sliding block 71 moves in the annular track. After the stretching stops, the sliding block 71 can move along the direction of the annular track under the action of the spring 51 and finally lock into the stop opening, thereby realizing the stop retraction of the connecting line 4, which makes it convenient for the user to pull out the required length as needed.

[0032] like Figure 2 and Figure 3 As shown, in order to ensure a stable electrical connection between the connecting wire 4 and the wireless charging mechanism 3 during the stretching and winding process, a sliding circuit board 6 is provided on the surface of the rotating disk 2 facing the wireless charging mechanism 3 in this embodiment. The end of the connecting wire 4 is electrically connected to the sliding circuit board 6, and the surface of the sliding circuit board 6 is in slidable contact with the surface of the wireless charging mechanism 3. Thus, when the rotating disk 2 rotates to wind or unwind the connecting wire 4, the sliding circuit board 6 rotates with the rotating disk 2 and always remains in contact with the surface of the wireless charging mechanism 3, thereby achieving a stable connection between the connecting wire 4 and the wireless charging structure.

[0033] Specifically, such as Figure 2 and Figure 3As shown, the wireless charging mechanism 3 of this embodiment includes a PCB board 31 disposed on the inner surface of the upper cover and a charging coil 32 disposed on the surface of the upper cover and electrically connected to the PCB board 31. When the electronic device is charging, it comes into contact with the charging coil 32, and charging is performed under the action of electromagnetic induction. In order to ensure that the charging coil 32 can always supply power during the process of the rotating disk 2 rotating and the connecting wire 4 stretching and contracting, this embodiment provides an annular contact portion 311 on the surface of the PCB board 31 facing the sliding circuit board 6, and provides a connecting seat 61 on the surface of the sliding circuit board 6 that can slide against the surface of the annular contact portion 311. During the rotation of the rotating disk 2, the connecting seat 61 can slide on the surface of the annular contact portion 311 and always be in contact with it, thereby realizing the electrical connection between the two. In this embodiment, the annular contact portion 311 is a metal sheet, and the connecting seat 61 is provided with a plurality of metal springs protruding toward one side of the PCB board 31. After the rotating disk 2 is installed into the shrinkage space of the housing 1, the metal springs on the connecting seat 61 can abut against the annular contact portion 311 of the PCB board 31 and produce a certain deformation, thereby ensuring a stable connection between the two.

[0034] In addition, one or more connectors 61 can be provided. In this embodiment, three connectors 61 are provided, and the three sliding connectors 61 are arranged at equal angles around the surface of the PCB board 31. This not only ensures a stable electrical connection, but also improves the balance performance of the telescopic cable module in this embodiment, thereby facilitating the stable extension and retraction of the connector 4.

[0035] like Figure 2 and Figure 3 As shown, the surface of the upper shell 11 in this embodiment is also provided with a magnet 8, and the magnet 8 is arranged around the outer ring of the charging cable, so that when the electronic device is wirelessly charged on the shell 1, it can be attracted by the magnet 8, thereby ensuring the stability of the electronic device when charging.

[0036] In summary, the working principle of this embodiment is as follows: This embodiment sets a rotating disk 2 inside the housing 1, and sets a winding mechanism 5 on the rotating disk 2 to drive the rotating disk 2 to rotate, so that the connecting wire 4 can be wound onto the rotating disk 2 or pulled out from the rotating disk 2 under the action of the winding mechanism 5. Thus, when the connecting wire 4 is not in use, it can be wound onto the rotating disk 2 by the winding mechanism 5, which can avoid the connecting wire 4 from getting tangled or damaged; and it can be pulled out at will during use, which is convenient.

[0037] Furthermore, by setting a wireless charging mechanism 3 on the surface of the housing 1 and a sliding circuit board 6 on the surface of the rotating disk 2 that is electrically connected to the connecting wire 4 and slidably connected to the wireless charging mechanism 3, the connecting wire 4 can achieve electrical connection with the wireless charging mechanism 3 through the sliding circuit board 6 when it is being wound or stretched, thereby achieving stable power transmission and thus achieving stable charging of the wireless charging mechanism 3.

[0038] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
