1. Field of the Invention
The present invention relates to a power supply device, and more particularly to a multi-function power supply device for a wristwatch cell phone and a tablet cell phone.
2. Description of the Prior Art
A cell phone is a common portable communication apparatus. With the development of science and technology, the functions of the cell phone are increased day by day. These days, people rely on a cell phone increasingly. A cell phone becomes an essential appliance for the modern life. For the user to carry the cell phone conveniently and to use the cell phone at any time, different types and different functions of cell phones are developed accordingly. A wrist watch cell phone and a tablet cell phone become a mainstream trend.
In general, different types of cell phones must cooperate with different power supply devices to supply power. When the user replaces a cell phone or owns at least two different types of cell phones, he/she has to use different power supply devices. The user may own a number of power supply devices, which becomes a trouble for the user. When the different cell phones need to be charged, the user has to use different power supply devices to cause great inconvenience. Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve this problem.
The primary object of the present invention is to provide a multi-function power supply device for a wristwatch cell phone and a tablet cell phone. The multi-function power supply device can be used conveniently for supplying power to a wristwatch cell phone and a tablet cell phone respectively.
In order to achieve the aforesaid object, the multi-function power supply device for a wristwatch cell phone and a tablet cell phone of the present invention comprises a main body. The main body is pivotally connected with a support board. The top side of the support board is formed with a slide trough. The main body is provided with a movable board disposed in the slide trough. The movable board is slidable in the slide trough. The main body comprises a pair of curved wings which are pivotally connected to left and right sides of the support board. The rear of the main body is pivotally connected with a plug. A battery unit is provided in the main body. The battery unit is electrically connected with the plug for storing power. A power supply coil is provided in the movable board. The power supply coil is electrically connected with the battery unit.
The movable board of the multi-function power supply device for a wristwatch cell phone and a tablet cell phone of the present invention is selective to be retracted into the slide trough to form a first state or extended to the top side of the support board to form a second state. When the multi-function power supply device is in the first state and a wristwatch cell phone is placed on the support board, the multi-function power supply device will supply power to the wristwatch cell phone. When the multi-function power supply device is in the second state and a tablet cell phone is placed on the support board and the movable board, the multi-function power supply device will supply power to the tablet cell phone.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.
The main body 10 has an insertion trough 11 thereon and a USB plug 12 disposed at the bottom of the insertion trough 11. In the present invention, the insertion trough 11 is disposed at the front side of the top of the main body 10. The main body 10 comprises a lid 13 which is pivotally connected to the front edge of the insertion trough 11. The lid 13 is selective to cover the insertion trough 11. The main body 10 comprises a support board 14 which is pivotally connected to the rear edge of the insertion trough 11. The top side of the support board 14 is formed with a slide trough 141. The main body 10 is provided with a movable board 15 disposed in the slide trough 141. The movable board 15 is slidable in the slide trough 141. The movable board 15 can be retracted into the slide trough 141 to form a first state or extended to the top side of the support board 14 to form a second state, as shown in
The plug is pivotally connected to the rear of the main body 10. When not in use, the plug can be pivoted to the bottom of the main body 10. In the present invention, the plug is pivotally connected to the bottom of the rear of the main body 10.
The electric connector is provided at the rear of the main body 10 for connecting with an external power source. In the present invention, the electric connector is a USB connector. One end of the electric connector is plugged to the bottom of the rear of the main body 10, and the other end is electrically connected with a computer or other external power sources.
The battery unit 40 is disposed in the main body 10. The battery unit 40 is electrically connected with the plug and the electric connector for storing power.
The power supply coil 50 is disposed in the movable board 15. The power supply coil 50 is electrically connected with the battery unit 40.

When the multi-function power supply device 100 is used for supplying power to the wristwatch cell phone 200, through the plug and by using the mains power supply, it supplies the required power. The electricity is stored through the battery unit 40 and converted to the required power for the wristwatch cell phone 200 and then supplies to the power supply coil 50. By the power supply coil 50, the electricity is converted to magnetism. The induction coil inside the wristwatch cell phone 200 will generate electricity due to electromagnetic induction, and the electricity is supplied to the wristwatch cell phone 200. This can supply power to the wristwatch cell phone 200.

When the multi-function power supply device 100 is used for supplying power to the tablet cell phone 300, through the plug and by using the mains power supply, it supplies the required power. The electricity is stored through the battery unit 40 and converted to the required power for the tablet cell phone 300 and then supplies to the power supply coil 50. By the power supply coil 50, the electricity is converted to magnetism. The induction coil inside the tablet cell phone 300 will generate electricity due to electromagnetic induction, and the electricity is supplied to the tablet cell phone 300. This can supply power to the tablet cell phone 200.
It is noted that, no matter the multi-function power supply device 100 is in the first state or the second state, the movable board 15 is exposed out of the front side of the support board 14 for the wristwatch cell phone 200 and the tablet cell phone 300 to direct contact with the movable board 15, such that the power supply coil 50 embedded in the movable board 15 can approach the wristwatch cell phone 200 and the tablet cell phone 300 to enhance the power supply function of the multi-function power supply device 100 for the wristwatch cell phone 200 and the tablet cell phone 300.
It is noted that the multi-function power supply device 100 uses the mains power supply to supply the required power through the plug, alternatively, it can be connected with a computer or other external power sources to supply the required power through the electric connector.
Besides, referring to
It is noted that the battery unit 40 can be a conventional dry battery. The multi-function power supply device 100 can directly use the electricity of the dry battery to supply power to the wristwatch cell phone 200 and the tablet cell phone 300.
Therefore, the multi-function power supply device 100 not only enhances the interchangeability of the cell phones but also provides more selectivity of the cell phones for the user.
