DETAILED DESCRIPTION

[0016] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept to be protected by the present invention.

[0018] The working principle of the charger capable of detecting the battery of the utility model is realized by the cooperation among the charging housing 1, the charge measuring device 2, the conversion unit 3, the control unit 4, the bobbin 5, the servo motor 6 and the take-up frame 7. Figures 1 to 4 As shown, the servo motor 6 can drive the wire take-up frame 7 to rotate the wire reel 5, and the wire 10 passes through the wire reel 5 and is connected to the conversion unit 3. Therefore, during the rotation of the wire take-up frame 7, the wire take-up frame 7 will abut against the wire 10 and gradually wind the wire 10 on the wire reel 5, so that the wire 10 exposed outside the charging shell 1 will be gradually stored in the charging shell 1, and will not affect the connection between the wire 10 and the conversion unit 3. When the wire 10 needs to be used, the user holds the end of the wire 10 exposed outside the charging shell 1, and the servo motor 6 reverses and causes the wire take-up frame 7 to gradually release the wire 10, so that the user can pull the wire 10 out of the charging shell 1. During the charging process, the conversion unit 3 discharges to the battery connector 9 to charge the battery, and the charge measuring device 2 detects the state of the battery. The charge measuring device 2 can be a charge meter. The charge measuring device 2 feeds back a signal to the control unit 4. The control unit 4 controls the display screen 8 to display the battery power information. Compared with the traditional charger, the charger that can detect the battery can store the wires 10 and avoid the exposed wires 10 being too long and easily causing pedestrians to trip. The charge measuring device 2 and the control unit 4 can cooperate to detect the battery and display the battery power on the display screen 8, so that the user can know the battery charging status and disconnect the charger in time after the battery is fully charged.

[0019] Specifically, a control switch 12 and a display light 13 are provided on one side of the charging housing 1 between the battery connector 9 and the wire 10, and an opening 14 is provided on one side of the charging housing 1 at the position of the wire 10, and the wire 10 is slidably connected to the charging housing 1 through the opening 14, wherein the control unit 4 includes a single-chip microcomputer controller and a control power supply, and the control power supply is electrically connected to the single-chip microcomputer controller, such as Figures 1 to 4 As shown, the display light 13 can be used to indicate the full state of the battery and the charging state of the battery. The control switch 12 and the display light 13 are electrically connected to the control unit 4 respectively. The single-chip controller of the control unit 4 controls the display screen 8 and the display light 13 to work according to the signal fed back by the charge meter 2.

[0020] Furthermore, the wire drum 5 is fixed in the charging shell 1 by a bracket, and the notches of the through slot 11 are respectively arranged at the center of the top surface of the wire drum 5 and the bottom of the side wall of the wire drum 5, and the wire 10 is inserted from the notch of the through slot 11 located at the bottom of the side wall of the wire drum 5, and the wire 10 passes through the notch of the through slot 11 located at the center of the top surface of the wire drum 5. Furthermore, the wire take-up frame 7 includes a turret body 15 and two wire take-up rods 16, the middle part of the turret body 15 is connected to the output end of the servo motor 6, and the turret body 15 is rotatably connected to the bottom surface of the wire drum 5, and the two wire take-up rods 16 are arranged on the turret body 15, wherein the wire take-up rod 16 is slidably connected to the turret body 15 through a sliding rod 17, and a spring seat 18 is arranged at one end of the sliding rod 17 away from the wire take-up rod 16, and the spring seat 18 is connected to the turret body 15 through a compression spring 19, and the compression spring 19 is sleeved on the sliding rod 17, as shown in FIG. Figures 1 to 4 As shown, the servo motor 6 drives the rotating frame body 15 and the wire-taking rod 16 to rotate, and the wire-taking rod 16 abuts against the portion of the wire 10 inserted into the wire drum 5 and presses the wire 10 against the side wall of the wire drum 5. As the wire-taking rod 16 rotates, the wire-taking rod 16 gradually winds the wire 10 on the wire drum 5 so that the wire 10 can be stored in the charging housing 1, and as the number of wires 10 on the wire drum 5 increases, the wire 10 can drive the wire-taking rod 16 to move outward, and the sliding rod 17 moves outward with the wire-taking rod 16 and compresses the compression spring 19 through the spring seat 18, so as to increase the distance between the wire-taking rod 16 and the side wall of the wire drum 5 to accommodate the wire 10.
