[0031] like Figures 1-4 As shown, a wireless charging device includes a vehicle mount mounted on an electric bicycle or electric motorcycle, a power take-up base 1, a power adapter 2, and a wireless charging assembly 3. The power take-up base 1 is connected to the power input terminal of the power adapter 2 via a wire. The power take-up base 1 has a plug adapted to the charging port of the electric motorcycle or electric bicycle. The power take-up base 1 draws power from the charging port of the electric motorcycle or electric bicycle through its plug, thereby providing power to the power adapter 2. The wireless charging assembly 3 is electrically connected to the power output terminal of the power adapter 2, which provides a stable voltage and current to the wireless charging assembly 3. The wireless charging assembly 3 includes a housing 31, a charging coil disposed within the housing 31, and a fixing adhesive 32 attached to the housing 31. The charging coil is disposed inside the housing 31 and sealed with glue or by providing a sealing gasket at the mating point of the housing 31 to increase its airtightness and facilitate waterproofing. The fixing adhesive 32 is a 3M adhesive or a self-adhesive sticker. The wireless charging component 3 is attached to the vehicle mount using adhesive tape 32. Before being attached, the adhesive tape 32 is covered with release paper 33 to protect it. The power adapter 2 includes a housing and a PCB board inside the housing. The PCB board has a fast charging power module and a compatible drive circuit to achieve fast charging for the wireless charging component 3.

[0032] like Figure 3As shown, the power adapter 2 has a rectangular shell and a rectangular back plate. The back plate has ventilation holes 21 for heat dissipation of the PCB board. Two sets of ventilation holes 21 are located at opposite corners of the rectangular back plate, forming a ventilation channel through the PCB board and effectively improving heat dissipation.

[0033] In some exemplary embodiments, the housing of the power adapter 2 is also provided with adhesive, allowing the power adapter 2 to be attached to a vehicle mount using the adhesive. When the vehicle mount is made of a material that can be attracted by magnets, magnets are also embedded in the housing of the power adapter 2.

[0034] like Figure 1 and Figure 2 As shown, in some exemplary embodiments, the power output terminal of the power adapter 2 is also electrically connected to a charging cable 4. A charging plug 41 is provided at the end of the charging cable 4 furthest from the power adapter 2. The charging plug 41 is configured as a PD male connector, a TP-YE-C male connector, or a Lightning interface male connector. This allows the present invention to wire charge a mobile phone via the charging cable 4, and also allows the present invention to charge two smart electronic devices simultaneously.

[0035] Example 2

[0036] like Figure 5 The wireless charging device shown includes a power outlet 1, a power adapter 2, and a wireless charging component 3. The power outlet 1 is connected to the power adapter 2 via a plug and is used to connect to an electric motorcycle or electric bicycle to draw power for the power adapter 2. The wireless charging component 3 is electrically connected to the power output terminal of the power adapter 2. The wireless charging component 3 includes a housing 31, a charging coil disposed in the housing 31, and a magnetic 34 embedded in the housing 31. The wireless charging component 3 is magnetically fixed to a vehicle mount with a magnetic attraction effect by the magnetic 34. The magnetic 34 is embedded on the back of the wireless charging component 3. The magnetic 34 can be any one of a ring structure, a circular structure, or a rectangular structure. The magnetic 34 is used to connect and fix with the vehicle mount with a magnetic attraction effect, quickly completing the installation and fixation of the wireless charging component 3 on the vehicle mount. The magnetic 34 can be a closed ring structure or a non-closed ring structure.

[0037] Thus, when the number of magnetic 34 is set to one, the magnetic 34 is located in the middle of the back of the wireless charging assembly 3. When the number of magnetic 34 is set to multiple, the magnetic 34 is located near the four corners or near the opposite sides of the back of the wireless charging assembly 3.

[0038] The power adapter 2 includes a housing 20 and a charging circuit board disposed inside the housing 20. A charging socket 22 is provided on the charging circuit board, and the charging socket 22 is connected to the plug on the power outlet 1. The charging socket 22 is configured as a DC female or a TPI-C female, and the charging socket 22 is compatible with the plug on the power outlet 1. At least one magnetic element 23 is embedded in the outer shell 20. Both the magnetic element 23 and the magnetic body 34 are magnets or structures with magnetic attraction. In this embodiment, there are four magnetic elements 23, which are set on any side of the outer shell 20 and near the four corners. By setting the magnetic elements 23 and the magnetic body 34, the power adapter 2 and the wireless charging component 3 can be quickly installed and fixed on the car phone holder with magnetic effect. The power adapter 2 can be installed and fixed on the back of the car phone holder, and the wireless charging component 3 can be installed and fixed on the opposite side and aligned with the wireless charging part on the phone. The magnetic element 23 can be any one of a ring structure, a circular structure, or a rectangular structure. The shape of the power adapter 2 can be any one of a rectangular structure, a circular structure, or an elliptical structure. The thickness of the power adapter 2 is set to 0.2-1 cm. By setting a thin outer shell, it is easier for users to carry around and more convenient.

[0039] In summary, the power outlet 1 of this invention can be plugged into the charging port of an electric motorcycle or electric bicycle to draw power. Simultaneously, the wireless charging component 3 of this invention can be adhesively or magnetically fixed to a magnetically attached vehicle mount used on an electric bicycle or electric motorcycle, thereby enabling the wireless charging component 3 to charge a mobile phone placed on the mount. Therefore, this invention is suitable for use on electric motorcycles or electric bicycles.
