DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
In the following, the vehicular charger of the present invention is further explained in connection with the figures.
Embodiment 1
As shown in FIGS. 1 to 7, the vehicular charger of the present invention, which comprises a main casing body 1 and a secondary casing body 2 which is arranged on both radial side of the main casing body 1 and is rotatable matched with the main casing body 1; a chargeable source part 3 is provided inside said main casing body 1; the chargeable source part 3 can be a rechargeable battery, and also can be a rechargeable lithium battery; a circuit board 4 electrically connected to the chargeable source part 3 is arranged on one end face of said main casing body 1; an interface is arranged on the circuit board 4; said interface has two kinds in total, one of which is a charging interface 5 for charging the chargeable source part 3, and the other of which is a USB interface 6 for charging other electronic devices; an illumination assembly 7 is mounted inside said secondary casing body 2; the illumination assembly 7 is charged by the chargeable source part 3; a switch 8 for controlling the ON/OFF of the illumination assembly 7 is provided on said circuit board 4. Two secondary casing bodies 2 are arranged on both side of the main casing body 1 of the embodiment and are rotatable matched with the main casing body 1; each secondary casing body 2 is provided with one illumination assembly 7. Said switch 8 includes two independent switches 8, enabling individually controlling of those two illumination assemblies 7, so as to fulfill the people's usage requirements. A magnet 9 is mounted on said secondary casing body 2; said secondary casing body 2 includes a main body 10 rotatable matched with the main casing body 1 as well as an upper cover 11 mounted on the main body 10. A mounting slot 12 is provided on said main body 10. Said magnet 9 is arranged inside the mounting slot 12. When a user opens the illumination assembly 7 so as to apply priming illumination onto an object, the magnet 9 arranged on the secondary casing body 2 can be used to absorb the vehicular charger of the embodiment onto a ferromagnetic object; thus, the user can release his/her hands for operation as needed.
A terminal cover 13 embedded into the main casing body 1 is mounted on one end face of said main casing body 1. An outer cover 14 clamped and fixed with the main casing body 1 is arranged outside the terminal cover 13. One side of said outer cover 14 is provided with an elastic L-shaped clamping arm 15 integrated formed with said outer cover 14. A buckle 16 clamped by the clamping arm 15 is provided on the outer cover 14.
