[0030] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0031] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] Example 1:

[0033] like Figures 1 to 7 As shown, this embodiment proposes a charger that is convenient for storing wire harnesses, including a winding shell 1, a winding reel 2, a locking assembly 3, a data cable 4, a connecting shaft 5, a wire threading hole 6, a connecting slot 7, a one-way toothed disc 8, a cavity 9, a wire clamping slot 10 and a coil spring 11 arranged inside the cavity 9.

[0034] The winding shell 1 serves as a container for winding the charger wire harness. Figure 5 As shown, the winding shell 1 is two symmetrical halves of the shell, which are spliced together by studs and screws. A connecting shaft 5 is fixedly connected to the center of the inner side of one half of the shell, and the other end of the connecting shaft 5 passes through the other half of the shell. A winding drum 2 is arranged inside the winding shell 1. The center of the winding drum 2 and the connecting shaft 5 are rotatably connected together, and there are wire guards on both sides of the winding drum 2. One-way toothed discs 8 are fixedly connected on both sides of the outside of the winding drum 2. A cavity 9 is opened inside the winding drum 2, and a coil spring 11 is arranged inside the cavity 9. The inner end of the coil spring 11 and the connecting shaft 5 are connected. The shafts 5 are fixedly connected together, the outer end of the coil spring 11 and the inner outward side wall of the cavity 9 are fixedly connected together, and locking sprockets 301 are provided on both sides of the interior of the winding shell 1, and the locking sprockets 301 and the one-way sprockets 8 are engaged together. When the winding reel 2 is rotated, when it is turned in the direction of tightening the coil spring 11, the one-way sprockets 8 on both sides of the winding reel 2 rotate, and the locking sprockets 301 on both sides are squeezed by the inclined surfaces of the teeth, so that the winding reel 2 can rotate, and when the winding reel 2 rotates, the locking sprockets 301 on both sides approach and move away from each other to perform reciprocating motion.

[0035] The locking sprockets 301 are fixedly connected to the sides of the locking sprockets 301 that are separated by the squeeze, and three evenly distributed guide posts 302 are fixedly connected to the sides of the locking sprockets 301 that are away from each other. Three evenly distributed connecting slots 7 are provided on both sides of the interior of the winding shell 1. The other ends of the guide posts 302 connected to the locking sprockets 301 extend from the inside of the connecting slots 7 to the outside of the winding shell 1. Control pull blocks 304 are provided on both sides of the outside of the winding shell 1. The control pull blocks 304 can not only facilitate the control of the locking sprockets 301 from the outside of the winding shell 1, but also prevent the locking sprockets 301 from approaching each other and separating from the winding shell 1. An extrusion spring 303 is mounted on each guide post 302. The extrusion spring 303 squeezes the locking sprockets 301 in the direction of approaching each other between the sides of the locking sprockets 301 that are away from each other and the inside of the winding shell 1, so that the locking sprockets 301 clamp the winding reel 2.

[0036] However, after the external force is removed, the coil spring 11 rebounds, and the teeth between the locking sprocket 301 and the one-way sprocket 8 are engaged, and the locking sprocket 301 clamps the one-way sprocket 8 and locks it. The coil spring 11 cannot rebound automatically, and the locking sprocket 301 needs to be pulled away from each other by controlling the pull block 304 to remove the lock of the winding reel 2. The coil spring 11 can drive the winding reel 2 to rotate. A bridge-shaped wire clamping groove 10 is opened on the outside of the winding reel 2 near the side of the half shell tightened with the screw. The two ends of the bridge-shaped wire clamping groove 10 are transitioned by arcs to reduce the bending of the clamped wire harness (the wire clamping groove 10 can also be opened in a shape with a high tangency to the winding reel 2 according to the winding of the wire harness, and the specific opening can be adjusted as needed). The position of the wire clamping groove 10 avoiding the cavity 9 is as shown in FIG. Figure 7 As shown, the middle position of the data cable 4 of the charger is stuck in the inside of the cable clamping slot 10, and the two ends are respectively passed through the inside of the wire threading holes 6 on the front and rear of the outside of the winding shell 1. In order to reduce the scratches and wear of the wire threading holes 6 on the surface of the data cable 4, protective bushings 13 are embedded in the inside of the two wire threading holes 6 to protect the surface of the data cable 4. A charging plug 12 for use with the USB interface of the data cable 4 is provided on the outside of the winding shell 1. Like the chargers on the market, the data cable and the plug can be separated, and the easily damaged data cable can be replaced. The same detachable shell and the cable clamping slot 10 that can facilitate the reassembly of the data cable make it more convenient to replace the data cable.

[0037] It should be noted that after the data cable 4 is re-inserted into the cable slot 10, the data cable is wound in the original direction, and when the coil spring 11 fully rebounds, the data cable 4 is ensured to be completely reeled in. When the data cable 4 is completely reeled in, both ends of the data cable 4 extend 2 cm from the inside of the threading hole 6. In this way, when the reeling is completed, the pulling of the data cable end can be reduced. When in use, the data cable 4 can be pulled as needed (just pull the two ends of the data cable) to adjust the length of the data cable as needed to avoid the cable harness being too long. After use, the control pull block 304 can be pulled away from each other to automatically reel in the data cable 4.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
