[0027] like Figure 4-Figure 6As shown, a rectangular groove 301 is provided on the bottom shell 3, and the length direction of the rectangular groove 301 is along the radial direction of the central axis 6 of the wire drum. A rectangular sliding groove is provided on the groove side wall of the rectangular groove 301, and a sliding block 9 is slidably set in the rectangular groove 301. Both sides of the sliding block 9 are provided with sliding block parts adapted to the rectangular sliding groove. A boss 901 is provided on the upper end surface of the sliding block 9, and the boss 901 is a cylindrical structure. A swing track 302 is provided on each side of the rectangular groove 301 on the bottom shell 3, and the two swing tracks 302 are perpendicular to the rectangular groove 301.

The motion track groove 802 is provided with at least four fixed corners for stopping the boss 901, and the rest are non-obstructive slideways, and the four fixed corners are respectively: the first corner 804, the second corner 805, the third corner 806 and the fourth corner 807. A gear stand 801 is provided on the swing member 8, and the swing member 8 is driven to slide through the gear stand 801 when the active member 7 rotates. Two tooth grooves 701 adapted to the gear stand 801 are symmetrically provided on the active member 7. When the gear stand 801 is engaged with the tooth groove 701, it is the stroke initial point or stroke end point of the winding mechanism. There are two groups of tooth grooves 701, and the two groups of tooth grooves 701 are arranged oppositely. When the active member 7 rotates clockwise, the tooth groove 701 pushes the gear stand 801 to the right, thereby pushing the swing member 8 to move to the right along the swing track 302; when the active member 7 rotates counterclockwise, the tooth groove 701 pushes the gear stand 801 to the left, thereby pushing the swing member 8 to move to the left along the swing track 302. A tension spring 12 is provided at each end of the swing member 8. One end of the tension spring 12 is connected to the swing member 8, and the other end is connected to the bottom shell 3. The positions where the two tension springs 12 are connected to the bottom shell 3 are located on both sides of the active member 7. The tension spring 12 can be used to reset the swing member 8. When the swing member 8 moves to the right side of the swing track 302, the tension spring 12 on the left side of the swing member 8 forms a stretched state, which has a certain reset rebound force. When the swing member 8 moves to the left side of the swing track 302, the tension spring 12 on the right side of the swing member 8 forms a stretched state, which has a certain reset rebound force. Pull the charging cable, the cable drum 5 rotates in a clockwise or counterclockwise direction, and the swing member 8 moves to the right or left along the swing track 302. Release the charging cable, and the swing member 8 slides to the left to the center of the cable drum 5. This is the travel path of the swing member 8 when the charging cable is in a stretched state. Pull the charging cable, the cable drum 5 rotates counterclockwise or clockwise, and the swing member 8 moves rightward or leftward along the swing track 302; release the charging cable, and the swing member 8 slides to the left or right side of the cable drum 5, which is the travel path of the swing member 8 when the charging cable is rolled into a retracted state.

[0028] Working principle of the utility model: the charging cable is wound on the wire drum 5, and the wire drum 5 is fixedly connected to the first PCB board 10 and the active component 7, so when the wire drum 5 is rotated, the first PCB board 10 and the active component 7 rotate synchronously following the running direction of the wire drum 5. A spring is fixedly connected between the wire drum 5 and the wire drum center axis 6, and when the wire drum 5 rotates, the spring is in a tightened state. When the wire drum 5 is in the stretching stroke locking, the sliding block 9 is located at the end of the rectangular groove 301 away from the wire drum center axis 6, the boss 901 on the sliding block 9 is at the first corner 804 of the swinging member 8, the swinging member 8 is in the middle position, and the gear 801 of the swinging member 8 is inserted into the tooth groove 701 of the active component 7 to complete the stroke locking. When the charging line is pulled outward again, the swing member 8 moves along the direction of rotation of the active member 7, and the toothed platform 801 on the swing member 8 is disengaged from the toothed groove 701 on the active member 7. As the swing member 8 moves, the boss 901 originally located at the first corner 804 slides along the running path to the second corner 805, releasing the charging line, resetting the spring, and rotating the cable drum 5 in the opposite direction, and all the pulled charging lines are retracted into the shell. At the same time, the active member 7 rotates rapidly in the opposite direction with the resetting force of the spring, and the active member 7 pushes the swing member 8 to the left or right end in the opposite direction. While the swing member 8 moves to the left or right, the sliding block 9 slides toward the central axis 6 of the cable drum. When the boss 901 on the sliding block 9 slides to the third corner 806, the toothed platform 801 of the swing member 8 is again inserted into the toothed groove 701 of the active member 7, reaching a contracted locking state, which is the initial state at this time. When in use, pull the charging cable outward, drive the cable drum 5 to rotate, and the active member 7 is linked to rotate. While the active member 7 rotates, push the swing member 8 to slide left or right, and the boss 901 on the sliding block 9 slides to the fourth corner 807, release the charging cable, and the cable drum 5 rotates in the opposite direction until the gear 801 of the swing member 8 is inserted into the tooth groove 701 on the active member 7, and the sliding block 9 slides until its boss 901 enters the first corner 804 along the running path, completing the travel locking of the pull-out position, and repeating this process during use. The charging cables wound in the first cable reel 1 and the second cable reel 2 are electrically connected through the first PCB board 10, the second PCB board 11 and the electrode spring.

[0029] In summary, the utility model is provided with a double wire reel, which can increase the length of the wound charging cable without increasing the diameter of the product, and can also stretch the charging cable in any reel, so that the charging cable has more usage scenarios. The utility model is provided with a swinging member 8 and a sliding block 9, which cooperate with the running path on the swinging member 8, so that the stroke self-locking and automatic retraction operation are more stable, simple, and convenient to assemble. Tension springs 12 are provided at both ends of the swinging member 8, and two sets of tension springs 12 are used to produce the function of balancing and resetting the swinging member 8. The above is only a preferred embodiment of the utility model, and is not used to limit the utility model. For those skilled in the art, the utility model can have various changes and variations.
