2. Descriptions of Related Art
The fast development of modern technology has great impact on essential components present in our daily lives. One of the most common examples is an electronic device. By power sources available around us, the electronic devices bring tremendous convenience to our life and become one of daily essentials. To facilitate easy carrying of the electronic devices, most of them are mounted with rechargeable batteries for power supply.
However, although the rechargeable batteries can be recharged to full power again, a problem is raised when users go out and there is no city power available. Once power in the rechargeable batteries is run out, the electronic devices are unable to work. Thus there is still a space for improvement.
Therefore it is a primary object of the present invention to provide a flashlight battery charger.
In order to achieve above object, the flashing battery charger includes a flashlight, at least one rechargeable battery mounted in the flashlight and a charger. A socket is disposed on a rechargeable battery of a flashlight and is connected with a city power system for charging the rechargeable battery. After completing the battery charging, users can not only use the present invention to make the flashlight light up, but also plug a charger into the socket of the rechargeable battery. By an output terminal on the other end of the charger directly connected with various electronic products or connected with various electronic products by adaptors, power in the rechargeable battery is boosted by a boost unit in the charger so as to charge the connected electronic products to a level of full capacity. The flashlight battery charger is portable and easy to carry. After power in the battery of the electronic product being consumed mostly, the battery in the flashlight is used directly or is taken out of the flashlight for charging the electronic product to its maximum capacity. Thus the inconvenience caused by no power supply for electronic products can be avoided. The present invention has more practical values.
The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings, wherein:

Then a washer 222, the power storage unit 22, a pad 223, a foam washer 224, the charge-discharge protection circuit 221 and a positive electrode plate 225 are put into a space inside the battery receiving slot 212. The socket 23, a positive electrode 226, an electrode holder 227, a sticker 228, a negative electrode holder 229 and a negative electrode 220 are mounted into the plug receiving slot 213. The negative electrode 220 is fixed in the negative electrode holder 229 and the positive electrode 226 is fixed in the electrode holder 227. Then the negative electrode holder 229 and the electrode holder 227 are attached with each other by the sticker 228 therebetween. An opening of the socket 23 just faces a socket hole 214 of the left housing and the right housing 21. A gap between the dividing ribs 211 of the left housing and a right housing 21 allows wires that connect socket 23 with the power storage unit 22 as well as the charge-discharge protection circuit 221 to pass through. In order to save the space, flat wires are used. After corresponding components being set into the battery receiving slot 212 and the plug receiving slot 213, the left housing and the right housing 21 is welded by an ultrasonic welding machine. The positive electrode plate 225 is exposed through a hole on the right end of the left housing and the right housing 21 while the negative electrode 220 is exposed through a hole on the left end of the left housing and the right housing 21. Moreover, a projecting mounting rib 215 is disposed on an outer edge of the left housing and the right housing 21, corresponding to the locking slot 111 on an inner edge of the battery mounting space 11 of the flashlight 1. A stopping flange 216 is formed on an outer end of the projecting mounting rib 215, corresponding to the step-like edge 112 formed on the outer edge of the battery mounting space 11. Thus the projecting mounting rib 215 on the outer edge of the left housing and the right housing 21 and the locking slot 111 disposed on the inner edge of the battery mounting space 11 are located and locked with each other when the rechargeable battery 2 is loaded into the battery mounting space 11 of the flashlight 1. Meanwhile by the limit of the stopping flange 216 corresponding to the step-like edge 112 formed on the outer edge of the battery mounting space 11, the rechargeable battery 2 is loaded into the battery mounting space 11 only in a single direction. Thus the battery electrodes arranged in the wrong direction can be avoided. The rechargeable battery 2 is located stably, without rotation, in the battery mounting space 11 of the flashlight 1 and the socket hole 214 of the rechargeable battery 2 corresponds to the through hole 12 disposed on the side edge of the flashlight 1 precisely.
As to the socket 23 of the rechargeable battery 2 mounted in the flashlight 1, it can also be connected with an input terminal 31 of the charger 3. The charger 3 further includes a boost unit 32, as shown in
Thereby the socket 23 of the rechargeable battery 2 mounted in the flashlight 1 is connected with a city power system for charging the rechargeable battery 2. After the charging being completed, the rechargeable battery 2 can not only provide power to the flashlight 1 but also supply power to various electronic products by the input terminal 31 of the charger 3 connected with the socket 23 and the output terminal 33 on the other end of the charger 3 connected with the electronic products. The power in the rechargeable battery 2 of the flashlight 1 is boosted by the boost unit 32 of the charger 3 so as to charge the connected electronic products to the maximum capacity.
Moreover, refer to embodiments shown in
Furthermore, refer to
A light source 14 on a front end of the flashlight 1 can be changed according to users' requirements. For example, a light source for general illumination is used. Or as shown in
In summary, compared with the devices available now, the present has following advantages:
1. After the rechargeable battery inside the flashlight charged completely, the rechargeable battery supplies power to the flashlight for illumination.
2. The rechargeable battery mounted inside the flashlight is disposed with the socket that connects with various electronic products directly or connects with them by different adaptors. Thus power in the rechargeable battery inside the flashlight is boosted by the boost unit in the charger so as to charge the connected electronic product fully.
3. The flashlight of the present invention is not only a portable lighting device for users but also is a power source. The rechargeable battery mounted in the flashlight is used to charge the electronic products directly when the power of the battery in the electronic product is run out so as to avoid the inconvenience caused by no power source for electronic products.
Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details, and representative devices shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
