Embodiments of the invention

[0017] The multifunctional vehicle charger provided by the present invention is a two-in-one charger.

Referring to FIG. 1, in the present embodiment, the 2-in-1 charger includes a main body and a voltage conversion module (not shown) mounted in the main body. The main body includes a charging main body 20 and a charging tray 30, and the charging main body 20 is a cylinder having a rounded end for fitting an automobile cigarette lighter socket.

[0019] The cylinder 20 includes input electrodes 22 and 23. The input electrode 22 is located at the top end of the cylinder 20, and the input electrode 23 is located at the side of the cylinder 20. More specifically, the input electrodes 22, 23 all protrude from the inside of the cylinder 20 to the outside of the cylinder 20. Preferably, the input electrode 23 has a certain elasticity so as to be able to pass through the cylinder 20 when the cylinder 20 is inserted into the car cigarette lighter socket. The friction is stabilized at the car cigarette lighter socket. The input electrodes 22, 23 are connected to the voltage conversion module 42 to connect an external current from the input electrode to the voltage conversion module 42. After voltage conversion, the non-adaptive voltage in the automobile is converted into a mobile phone, an Apple watch, and other electronic devices. The lower voltage at which the device is charged. The converted voltage can be externally output through the charging pad 30 and the output port 37.

[0020] The charging tray 30 is provided with a coil 36 for external wireless charging, and the charging tray 30 is further provided with a plurality of The USB output port 37, the coil 36 and the USB output port 37 are connected to the voltage conversion module 42.

[0021] In addition, a circular wireless touch panel 35 with a concave-convex design is also disposed on the front surface of the base 32, and the wireless touch panel is used for charging the Apple watch. Correspondingly, the wireless contact pad is located above the coil 36 inside the base.

[0022] When the power source flows from the voltage conversion module 42 into the coil 36, the coil 36 generates an induced current. A charging source for the Apple Watch placed on the wireless touch panel 35 is provided through the wireless touch pad 35 on the surface of the base 32.

[0023] In the present embodiment, the charging tray 30 provided by the present invention is designed in the shape of "L", and the connecting portion 31 connected to the charging body 20 is a horizontal portion of "L", and the base 32 of the charging tray is " The vertical part of L". This design primarily provides a support for the charging of the Apple Watch. When the Apple Watch is charged, the side of one side of the watch can be placed against the connecting portion 31. This design also provides a fixed and protective effect on the watch while driving, preventing the watch from falling due to the jitter of the speed.
