DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1-6, a charging device for a light comprises a light body 1 and a charging assembly 2 which is connected to the light body 1. The light body 1 is assembled onto a bicycle. A printed circuit board 11 is disposed in the light body 1. The printed circuit board 11 is electrically connected to the charging assembly 2 and capable of storing the electric power. The charging assembly 2 has a base 21, an electrical connecting plate 22 and a plurality of wires 23. The electrical connecting plate 22 is connected to one side of the base 21, and the wires 23 are connected to another side of the base 21. The electrical connecting plate 22 pivots and bends relative to the base 21. The electrical connecting plate 22 is used to connect the present invention to a computer (not shown) for charging the light body 1. A plurality of metal conductors 24 is disposed on the electrical connecting plate 22. One portion of each metal conductor 24 is exposed out of the electrical connecting plate 22, and another portion of each metal conductor 24 is disposed into the electrical connecting plate 22. One end of each wire 23 is inserted into another side of the base 21 and connected to one end of another portion of each metal conductor 24, and another end of each wire 23 is electrically connected to the printed circuit board 11.
Referring to FIGS. 3-5, the characteristics of the electrical connecting plate 22 are described as following. The electrical connecting plate 22 is formed as rectangular shaped. The electrical connecting plate 22 has a bending portion 221 and a connecting portion 222 defined thereon. One end of the bending portion 221 is connected to the base 21, and another end of the bending portion 221 is connected to one end of the connecting portion 222. The bending portion 221 pivots and bends relative to the base 21 in a direction toward the wires 23. The connecting portion 222 moves along with the bending portion 221. The bending portion 221 further has an inner plate 2211 and a casing unit 2212 which covers the inner plate 2211 defined thereon. One end of the inner plate 2211 is connected to the base 21. The inner plate 2211 is flat and rectangular shaped. The inner plate 2211 is thinner than the electrical connecting plate 22. In order to make the electrical connecting plate 22 pivot and bend smoothly relative to the base 21, a wrinkling segment 2213 is defined at one end of the inner plate 2211 in one embodiment, wherein the wrinkling segment 2213 is formed as saw-toothed shaped; while, a flexible and thin segment (not shown) is defined at one end of the inner plate 2211 in another embodiment. The inner plate 2211 bends flexibly and smoothly relative to the base 21 because of the wrinkling segment 2213 or the flexible and thin segment. Therefore, the wrinkling segment 2213 or the flexible and thin segment prevents one end of the inner plate 2211 from breaking up when the inner plate 2211 pivots relative to the base 21.
Referring to FIG. 4, a plurality of guiding grooves 3 is opened on the inner plate 2211 and corresponds to the metal conductors 24 and the wires 23. Each guiding groove 3 is opened from one end of the inner plate 2211 to one end of the connecting portion 222. Each guiding groove 3 has a broad groove portion 31 and a narrow groove portion 32. The broad groove portion 31 is defined at one end of the connecting portion 222. One end of the narrow groove portion 32 is connected to the broad groove portion 31, and another end of the narrow groove portion 32 is opened toward the wrinkling segment 2213 or the flexible and thin segment and ended at one end of the inner plate 2211. Another end of another portion of each metal conductor 24 is embedded into the broad groove portion 31 of each corresponding groove 3. One portion of each metal conductor 24 abuts against the connecting portion 222. The casing unit 2212 covers not only the inner plate 2211 but also another end of another portion of each metal conductor 24 so as to prevent the metal conductors 24 from suffering electric leakage.
Referring to FIGS. 4-5, in order to connect the present invention to the computer smoothly and efficiently, one end of each wire 23 is inserted into another side of the base 21 firstly; and then, one end of each wire 23 is pulled out from one side of the base 21 and inserted into each corresponding guiding groove 3; lastly, one end of each wire 23 is connected to one end of another portion of each metal conductor 24, and one end of each wire 23 is covered by the casing unit 2212. Therefore, the electrical connecting plate 22 is capable of conducting electricity smoothly and prevents from the electric leakage. In addition, a receiving segment 2221 is defined at one side of the connecting portion 222. The metal conductors 24 are disposed in and abutted against the receiving segment 2221. The connecting portion 222 with the metal conductors 24 disposed thereon is thicker than the inner plate 2211. The receiving segment 2221 prevents the metal conductors 24 from protruding from the connecting portion 222 and allows the metal conductors 24 electrically connecting to the computer in an efficient fashion.
Referring to FIG. 4, in order to store the electrical connecting plate 22 in the light body 1 when the electrical connecting plate 22 is not necessary, the present invention further has a plurality of strips disposed on one side of the charging assembly 2. The strips surround three of four sides of the electrical connecting plate 22. One side which is not surrounded by the strips is at another end of the connecting portion 222. Therefore, when the electrical connecting plate 22 is not necessary, the electrical connecting plate 22 is stored in an area surrounded by the strips; when the electrical connecting plate 22 is necessary, a user pulls up the electrical connecting plate 22 from one side of the area which is not surrounded by the strips 12, so that the electrical connecting plate 22 leaves the area and is ready to be connected to the computer. In another embodiment, the present invention has a storage room 13 opened on one side of the charging assembly 2 for storing the electrical connecting plate 22. The depth of the storage room 13 is at least equal to the thickness of the electrical connecting plate 22. An indentation 131 is recessed on one side of the storage room 13 and corresponds to the connecting portion 222 of the electrical connecting plate 22. Therefore, the electrical connecting plate 22 is stored in the storage room 13 when the electrical connecting plate 22 is not necessary; and the user can pull up the electrical connecting plate 22 easily from the side of the indentation 131.
Referring to FIGS. 2-6, when the user needs to insert the charging assembly 2 into the computer for charging, firstly the electrical connecting plate 22 of the charging assembly 2 is pulled up from the light body 1 so as to make the wrinkling segment 2213 (the flexible and thin segment) of the electrical connecting plate 22 be perpendicular to the base 21 and the rest of the electrical connecting plate 22 be horizontal to the base 21; thereafter, the electrical connecting plate 22 is inserted into a port (not shown) of the computer, the electric power is transmitted from the computer to the printed circuit board 11 of the light body 1 via the metal conductors 24 and wires 23. Therefore, the electric power is stored in the printed circuit board 11 for lighting the light body 1. Referring to FIGS. 1-7, when the charging of the light body 1 is finished, the electrical connecting plate 22 can be pulled out from the port of the computer, and stored in the area surrounded by the strips or in the storage room 13.
Under this arrangement, when the light body 1 needs to be charged, the light body 1 is disassembled from the bicycle by the user firstly; and then, the electrical connecting plate 22 is pulled up and inserted into the port of the computer for charging. Therefore, the electric power is stored in the printed circuit board 11 of the light body 1, so that the light body 1 is charged and ready to illuminate. Besides, since the present invention does not need additional charging device for charging the light body 1, the present invention is light in weight and also environmental friendly.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
