2. Description of the Prior Art
A cell phone is a common portable communication apparatus. Along with the development of electronic technique, the functions of the cell phone are increasing day by day. The cell phone becomes an essential appliance in our modern life. However, the cell phone needs electricity when in use. The conventional cell phone proceeds with power transmission through a wired power supply device. By using the wired power supply device to proceed with power transmission for the cell phone, the range for the user to use the cell phone is limited to where the wired poser supply device is located. The cell phone cannot be charged anytime and anywhere. During using the cell phone, the cell phone may have a shortage of power. When the user wants to proceed with power transmission for the cell phone, the cell phone must be connected with the wired power supply device to supply the required power. This is not convenient for operation. In addition, the connection of the cell phone and the wired power supply device may have the risk of electric leakage. 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 wireless charge and discharge wrist band for placing a cell phone. The cell phone can be charged anytime and anywhere. The cell phone is coupled to the wireless charge and discharge wrist band without connection points for power transmission. During power transmission, the user can take the cell phone along. It is convenient to carry and use the cell phone.
In order to achieve the aforesaid object, the wireless charge and discharge wrist band for placing a cell phone of the present invention comprises a watch band. The watch band is provided with at least one battery. The battery is rechargeable and able to store electricity. The watch band is provided with a watch seat. The watch seat has an engaging trough thereon. The bottom of the watch seat is provided with a charge coil. The charge coil is embedded in the watch seat. The charge coil is connected with the battery. The top of the watch seat is provided with a power supply coil. The power supply coil is embedded in the watch seat. The power supply coil is connected with the battery.
The watch band of the wireless charge and discharge wrist band of the present invention is provided with the watch seat combined with the charge coil and the power supply coil for the watch band to combine with the wireless charge and discharge device. The cell phone is selectively engaged on the watch seat through the engaging trough. Through electromagnetic induction to transmit power, the cell phone can proceed with power transmission anytime and anywhere. During power transmission of the cell phone, the user can take the cell phone along. It is convenient to carry and use the cell phone and enhances the safety of using the cell phone.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.
The watch band 10 is made of a waterproof material, which has the resistance of water. The watch band 10 has a plurality of spaced V-shaped grooves 11 along a short axis thereof. The V-shaped grooves 11 are arranged along the short axis of the watch band 10 to traverse the watch band 10. Through the V-shaped grooves 11, the watch band 10 forms a multi-section crawler structure. Through the V-shaped grooves 11, the watch band 10 is formed with thin portions, such that the watch band 10 has better air permeability and is flexible. It is noted that the V-shaped grooves 11 are not limited to be disposed on the outer side of the watch band 10. The V-shaped grooves 11 may be disposed on the inner side of the watch band 10 for the watch band 10 to form a multi-section front crawler structure or a rear crawler structure.
The battery 20 is disposed on the watch band 10. The battery 20 is rechargeable and able to store electricity. The present invention has a plurality of batteries 20 which are spaced and embedded along the long axis of the watch band 10. The batteries 20 are respectively embedded between the V-shaped grooves 11, so that the batteries 20 and the V-shaped grooves 11 are spaced. The batteries 20 are electrically connected with one another.
The watch seat 30 is disposed on the watch band 10. In the present invention, the watch seat 30 is disposed at the middle position of the watch band 10. The watch seat 30 has an engaging trough 31 thereon. The engaging trough 31 has a trapezoid cross-section, namely, the engaging trough 31 is gradually enlarged from an upper opening to a bottom side thereof. One side of the engaging trough 31 extends to a circumferential side of the watch seat 30. The circumferential side of the watch seat 30 is formed with an insertion opening 311.
The main control board 40 is embedded in the watch seat 30, and the main control board 40 is connected with the batteries 20.
The charge coil 50 is disposed at the bottom of the watch seat 30 and embedded in the watch seat 30. The charge coil 50 is connected with the main control board 40. The charge coil 50 can generate electric current through electromagnetic induction to input the electric current to the batteries 20 for the batteries 20 to be charged.
The separator 60 is disposed above the charge coil 50 and embedded in the watch seat 30. The separator 60 is adapted to isolate magnetic field and prevent electromagnetic interference.
The power supply coil 70 is disposed above the separator 60 and at the top of the watch seat 30, and embedded in the watch seat 30. The power supply coil 70 is connected with the main control board 40. The power supply coil 70 is for the batteries 20 to output electric current so as to generate an induction field.
The NFC coil 80 is disposed at the surrounding side of the power supply coil 70 and embedded in the watch seat 30 and connected with the main control board 40.
