Detailed ways

As shown in Figure 1-8: the charger consists of a shell 1, a power contact 2, a screw cover 3, a side clip 4, an indicator light 5, a mobile phone plug 6, an outlet 7, a power cord 8, a reel 9, Press plate spring 10, take-up press plate 11, return spring 12, rectifier circuit board 13, spring 14, insurance tube 15, fixed shaft 16, axle sleeve 17, circuit contact sheet 18, spring fixed sheet 19, stop rib 20, stop The movable stopper 21 and the spring hole 22 of the pressing plate are formed.

As shown in Figure 1, the shell of the tortoise charger is oblate, and its left side is provided with a power contact 2, a screw cover 3 and a side clip 4 for insertion into a car cigarette lighter, and the right side is provided with a take-up pressure plate 11 for use To control the retraction of the mobile phone plug 6 and its power cord 8, the indicator light 5 is for displaying the charging status of the power supply and the mobile phone.

As shown in Figure 2-Figure 8: it is a schematic diagram of the basic structure of the utility model, the shell is formed by snapping the upper and lower parts into one body, and the cavity at the left end of the shell is equipped with a power contact 2, a safety tube 15, Spring 14; Rectifier circuit board 13 and a set of winding device are respectively installed in the cavity at the right end by fixed shaft 16 and axle sleeve 17 arranged at the center of the shell. One of the winding devices consists of a wire reel 9 and a circuit contact piece 18 arranged on one side of the wire reel, a power cord 8 wound on the wire reel, a return spring 12 arranged at the center of the wire reel, and Its spring fixing piece 19 is constituted, and wherein return spring 12 is installed in the center (as shown in Figure 5 ) on the other side of the reel through the spring fixing piece 19, and the other side reel 9 is also provided with a matching stopper The stop rib 20 of the sheet 21.

The working principle of the utility model is: the power supply provided by the car cigarette lighter socket is transmitted to the rectification circuit board 13 through the power contact 2 and the side clip 4, and the rectification output power is passed through the circuit contact piece 18 on the end surface of the corresponding winding reel 9 Pass to the mobile phone plug with power line 8, when connecting mobile phone charging, indicator light 5 can switch identification light signal along with battery full or not.

As shown in Fig. 4, Fig. 5 and Fig. 8: the stop convex rib 20 of the reel corresponds to the stop block 21 of the take-up pressure plate, when the plug of the mobile phone is pulled out, the return spring 12 is synchronously reversed And store the pulling force. When the pull-out is stopped, the stop catch 21 of the take-up pressure plate 11 is pushed by the pressure plate spring and buckles the stop rib of the reel. If the take-up pressure plate is pressed down, the reel is not restrained by the catch. , the return spring is the reverse action to automatically retract the power cord.
