AI Technical Summary
Existing data cable take-up boxes, such as those described in Chinese Patent 202020012434.4, are limited in their ability to provide multi-stage elongation and are less functional due to a single notch that restricts data cable extension to only one turn, making them less adaptable to various scenarios.
A pull-out and self-shrinkable data cable take-up box is designed with a top cover, lower cover, take-up tray, data cable, and clockwork spring. The take-up tray is movably attached to a rotating shaft, and a slide bar with multiple tracks and positioning lock notches allows for multi-stage elongation and automatic contraction, enabling precise control over data cable extension.
The solution provides a more practical and versatile data cable management system, allowing for multi-stage elongation and automatic contraction, which enhances convenience and usability across various scenarios while preventing tangles and damage.

Abstract
Description
[Technical field]
[0001] The present invention relates to the technical field of charging data cable box, and more particularly to a retractable and self-retracting data cable winding box. [Background technology]
[0002] The telescopic data cable is an electronic researcher's improvement of the original data cable in the row by using the principle of a tape measure, giving the data cable an automatic contraction function, making it convenient for users to carry and requiring little storage space. The traditional data cable can be automatically contracted at will, and no longer has the drawbacks of traditional data cables being knotted, torn, and taking up large space.
[0003] For example, Chinese Patent 202020012434.4 discloses a single-pull high-current fast charging data cable winding box, which installs the charging data cable in segments to ensure a relatively large bar installation space, and can install a large power bar and store a coarse charging data cable. The contact-type conversion conduction structure allows a large space and a high-speed circuit board to be installed in the middle of the circular track to realize the fast charging function. However, this structure only has one notch, and when the data cable is pulled out and released, the notch limits the position of the data cable and clamps it. In fact, only the distance of one turn can be pulled out, and even if it is pulled again, it can only increase the length of one turn and cannot be adjusted smaller, so the functionality is poor.

The protrusion 37 is provided on the left end of the branch block 34. A branch port 35 is provided at one end of the branch block 34. A positioning lock notch 36 is provided at the other end of the branch block 34. When the slide bar 211 slides into the branch port 35, the slide bar 211 switches between the first track 32 and the second track 33. After the slide bar 211 contracts and slides into the positioning lock notch 36, the movement of the data cable 40 and the winding tray 30 stops.
[0020] A V-shaped groove is provided in the positioning lock notch 36, and a locking part is provided at one end of the guide block 21. When the slide bar 211 contracts and slides into the positioning lock notch 36, the locking part hits the V-shaped groove. Here, a material with a cushioning effect, such as cushioning cotton, is provided on the locking part. When the slide bar 211 is released, the slide bar 211 slides into the positioning lock notch 36, and the cushioning cotton of the locking part can cushion a certain acting force and extend the service life. A mounting groove 38 and a communication hole 39 are provided on the surface of the winding tray 30, a circuit board 60 is provided in the mounting groove 38, the data cable 40 has a fixed end and an extending end, the fixed end of the data cable 40 passes through the communication hole 39 and is electrically connected to the circuit board 60, and a conductive sheet 61 is provided on the surface of the circuit board 60.
[0021] The upper cover 20 is provided with a circular printed circuit 22, and the conductive sheet 61 includes a first contact shrapnel 611 and a second contact shrapnel 612, which are in rotatable contact with the circular printed circuit 22, respectively.

[0023] An output wire 221 is connected to one end of the circular printed circuit 22, and a switch socket 222 is connected to the output wire 221. Various sockets for circuit transmission are connected to the switch socket 222, so that power can be supplied to the data cable 40. The charging socket of the data cable 40 is inserted into a mobile phone for charging.
[0024] The upper cover 20 and the lower cover 10 are engaged to form an inlet / outlet 70, and the extended end of the data cable 40 extends from the inlet / outlet 70. The data cable 40 can be extended from the inlet / outlet 70 or retracted into a retractable / self-retractable data cable winding box, whereby a protective cover is added to the inlet / outlet 70 to protect the head of the data cable 40 and effectively extend its service life.
[0025] A ring sleeve 301 is provided on the winding tray 30, a fixing clip 302 is provided next to the ring sleeve 301, a fixed end of the data cable 40 is fixed between the ring sleeve 301 and the fixing clip 302, a fixing portion 303 is provided on one end of the ring sleeve 301, the clockwork spring 50 is provided on the inner ring surface of the ring sleeve 301, one end of the clockwork spring 50 is fixed on the rotating shaft 11, and the other end of the clockwork spring 50 is fixed on the fixing portion 303.
[0026] Here, the fixed end of the data cable 40 is fixed between the ring sleeve 301 and the fixing clip 302, which ensures the stability of the data cable 40 during the extension and contraction process and prevents the data cable 40 from being accidentally dropped off or damaged during use, and one end of the clockwork spring 50 is fixed on the rotating shaft 11 and the other end is fixed on the fixing part 303. With this design, the winding tray 30 provides a uniform elastic force when the data cable 40 is extended or contracted, realizing an automatic extension function; when the user releases his / her hand, the data cable 40 will automatically contract due to the stored force of the clockwork spring 50; this automatic contraction characteristic, combined with the precise extension length control, provides the user with a convenient use experience and at the same time avoids the tangling and knotting problems of the data cable 40.
[0027] A locking groove 111 is provided on the surface of the rotating shaft 11, and one end of the clockwork spring 50 is mounted in the locking groove 111 to form an engaging connection.

[0029] In this embodiment, a retractable and self-retractable data cable winding box is provided. When the data cable 40 is pulled outward, the winding tray 30 is rotated, and the slide bar 211 slides closely against the block along the first track 32 until it reaches the position of the protrusion 37. The guide block 21 is then reversed on the branching port 35, and the slide bar 211 slides to the upper end of the branching block 34 and switches to the second track 33. Here, the slide bar 211 can slide back and forth along the first track 32 and the second track 33, and can be smoothly extended without being jammed. When the data cable 40 is fully extended, the slide bar 211 slides into the positioning lock notch 36 and is restricted, so that the data cable 40 cannot move. The data cable 40 is extended to its maximum length, and can be used in the same way as a normal data cable 40. After use, the data cable 40 is pulled once, the slide bar 211 is released from the restriction of the positioning lock notch 36, and the data cable 40 is automatically retracted by the stored force of the clockwork spring 50, causing the slide bar 211 to slide back and forth together along the first track 32 and the second track 33, and finally retracting the data cable 40 into the winding box.
[0030] By providing three positioning lock notches 36, the length can be adjusted in multiples of one-third of the cable, where three or more positioning lock notches 36 can be provided, allowing the user to easily control the extension length of the data cable 40, which is applicable to various scenarios, improving the convenience and experience of use; when not in use, the data cable 40 can be retracted into the small box in the middle to avoid the cable being tangled or knotted, and making it convenient to carry.
