Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1 to 4, in the present embodiment: the utility model provides a wireless rechargeable electric screwdriver and base thereof, includes base 1 and screwdriver 2, and the inside of base 1 is provided with first circuit board 11 and transmitting coil 13 respectively, and the tail end of screwdriver 2 is provided with rear end shell 20, and the inside fixedly connected with rechargeable battery 21 of screwdriver 2 is provided with second circuit board 22, magnetism isolating sheet 23 and receiving coil 24 respectively in the inside of rear end shell 20.
In this embodiment, a charging hole 10 is formed in a side surface of the base 1, a charging connector 12 is connected to a front surface of the first circuit board 11, and the charging connector 12 is located in the charging hole 10 and is used for connecting a charging wire.
The top of base 1 has offered standing groove 14, and transmitting coil 13 is close to standing groove 14, and transmitting coil 13's both ends are connected with first circuit board 11 for transmitting coil 13 circular telegram produces alternating magnetic field.
The second circuit board 22 is located at one side of the battery and connected with the battery, the magnetism isolating sheet 23 is located between the receiving coil 24 and the second circuit board 22, the magnetism isolating sheet 23 can play a magnetic isolation role between metal and the coil, the receiving coil 24 is close to the bottom of the rear end housing 20, and is convenient to be close to the transmitting coil 13, so that the charging rate is higher.
