Description

Technical Field

[0001] The utility model relates to the technical field of wireless charging, in particular to a portable wireless charger. Background Art

[0002] Wireless chargers are devices that use the principle of electromagnetic induction for charging. Its principle is similar to that of a transformer. A coil is placed at the transmitting end and the receiving end. The transmitting end coil sends an electromagnetic signal to the outside world under the action of electricity. The receiving end coil receives the electromagnetic signal and converts it into current, thereby achieving the purpose of wireless charging. Wireless charging technology is a special power supply method that does not require a power cord, relies on electromagnetic wave propagation, and then converts electromagnetic wave energy into electrical energy, ultimately achieving wireless charging.

[0003] The wireless charger itself still needs to be connected to a power source via a power cord. When the wireless charger is not in use, the power cord is not easy to store, is messy, or even entangled with other power cords, and is not easy to carry.

[0004] For example, the wireless charger disclosed in the Chinese patent with announcement number CN217335140U includes a heat dissipation housing, a working component and a semiconductor refrigerator. The heat dissipation housing includes a charging area, and the outer surface of the charging area is used to place the device to be charged. The heat dissipation housing is provided with a receiving cavity, and the working component and the semiconductor refrigerator are both arranged in the receiving cavity. The working component includes a charging coil, and the charging coil is used to charge the device to be charged. The semiconductor refrigerator includes a heating surface and a cooling surface, the cooling surface is in contact with the charging coil, and the heating surface is in contact with the heat dissipation housing, and the heat dissipation housing can dissipate heat and cool the semiconductor refrigerator.

[0005] The above wireless charger solves some defects existing in the prior art, but it does not have the function of storing the power cord when in use, making it inconvenient to carry.

[0006] To this end, a portable wireless charger is proposed. Utility Model Content

[0007] The purpose of the utility model is to provide a portable wireless charger, so as to solve or at least alleviate one or more of the above-mentioned problems and other problems existing in the prior art.

[0010] In a portable wireless charger according to the utility model, a through groove communicating with the connecting groove is formed on the top of the base.

[0011] In a portable wireless charger according to the utility model, the wire receiving groove is arranged in a spiral line shape.

[0012] In a portable wireless charger according to the utility model, the cross section of the connecting groove is arranged in an inverted Ω shape.

[0013] In a portable wireless charger according to the utility model, a groove is provided at the lower end of one side of the charging shell, a support plate is rotatably connected inside the groove, and a card slot is provided on the support plate.

[0014] In a portable wireless charger according to the utility model, an arc-shaped notch communicating with the groove is formed on the support plate.

[0015] The utility model has at least the following beneficial effects:

[0016] The utility model can quickly store the power cord by providing the wire collection groove and the connection groove. Moreover, by this arrangement, the interface of the power cord can be connected to the charging interface on the base for a long time, which reduces the plugging and unplugging frequency of the interface of the power cord and the charging interface on the base, and prolongs the service life of the charging interface. Moreover, the cross section of the wire collection groove is arranged in an inverted Ω shape, so that after the power cord is inserted into the wire collection groove, the narrow opening at the upper end of the wire collection groove can limit the power cord, effectively preventing the power cord from popping out of the wire collection groove, and making the wireless charger easy to carry.

[0017] By providing the through slot, when charging is needed, the power cord can be extended to the outside along the through slot, and charging is convenient when the charging housing is in a horizontal position;

[0018] The angle of the charging shell can be adjusted, and the wireless charger can be used as a mobile phone holder in conjunction with the support plate. BRIEF DESCRIPTION OF THE DRAWINGS
