Detailed description of the invention
The utility model provides a kind of screwdriver receiver with charging indication function, as depicted in figs. 1 and 2, receiver comprises columniform storage seat housing 1 and upper cover 2, the center of storage seat housing 1 is provided with along its axially extended screwdriver jack 3 with around a plurality of screwdriver bit accepting holes 4 be distributed in around screwdriver jack 3, and the center of upper cover 2 is provided with the central shaft hole 21 matched with screwdriver jack 3; Screwdriver can pass central shaft hole 21 and be inserted in screwdriver jack 3; Upper cover 2 covers mutually with storage seat housing 1 or is separated, and under upper cover 2 and storage seat housing 1 cover state, upper cover 2 lid covers screwdriver bit accepting hole 4, and the central shaft hole 21 of upper cover 2 is coaxial relative with screwdriver jack 3.When screwdriver bit is inserted into after in screwdriver bit accepting hole 4, screwdriver bit has at least part to be exposed to screwdriver bit accepting hole 4, facilitates picking screw screwdriver bit.
Wherein, battery 11 and electronics PCB charging storage chip 5 is provided with in storage seat housing 1, electronics PCB charging storage chip 5 has the charge port 51 for being connected with external charging power supply, charge port 51 is arranged at the outer wall of storage seat housing 1, the outer wall of storage seat housing 1 is provided with charging display lamp 6, be provided with conducting element 7 in screwdriver jack 3, screwdriver, battery 11 and conducting element 7 form the charge circuit of screwdriver; Electronics PCB charging storage chip 5, external charging power supply, battery 11 and charging display lamp 6 form the charge circuit of battery, and electronics PCB charging storage chip 5 has a flashing control circuitry.
Concrete, as shown in Figure 3, flashing control circuitry comprises U1 module and U2 module, and the reference output of U1 module is connected with the input of U2 module, and the reference voltage of the reference output of U1 module is 2.5V, the output of U2 module is connected with charging display lamp, the double operational that U2 module is made up of D1 amplifier, D2 amplifier, D1 amplifier and D2 amplifier are in series, and D1 amplifier forms square waveform and grows up to be a useful person, D2 amplifier forms square wave converter, and D1 amplifier and D2 amplifier form triangular-wave generator.Below the operation principle of flashing control circuitry of the present utility model:
When being divided into charging and after charging terminates;
