Description

Technical Field

[0001] The utility model relates to the technical field of charging devices, and in particular to a charging device capable of completely storing a data line through telescoping. Background Art

[0002] Since the charging head that can retract the data cable can store the data cable in the housing to avoid scattering and entanglement, it is welcomed by many users. However, after the traditional retractable data cable device is stored, the USB connectors at both ends of the data cable are still left outside, which is not only unsightly but also easy to damage. For this reason, someone invented a data cable charging device that can completely store the USB connector in the housing. For example, patent CN117175294 discloses a charging head that can store data cables steplessly. When the storage is completed, the USB interfaces at both ends of the data cable can be located inside the charging head to protect the data cable. However, the structure of the patent scheme for triggering the USB interface to pop up is too complicated, with many parts. Four springs are required for the ejection. Not only is the assembly operation cumbersome, but the cost is high, and it is more prone to failure, which reduces its reliability in use. To this end, the applicant has filed a utility model patent application entitled "A charging device that can completely accommodate a data cable". The device provides an elastic arm to the button, so that the elastic arm stops the data cable charging head that is completely retracted into the shell, and a pusher is provided to cooperate with a push-out spring to form a pop-up push structure. After pressing the button to release the elastic arm from stopping the charging head, the pusher can be driven by the pusher spring to push the charging head out of the shell. The device has fewer parts, a simpler structure, more convenient assembly operation, lower cost, and higher reliability. However, this solution still has some problems. For example, when the data cable passes through the shell and is pulled outward, it will generate friction with the shell. The pulling out and retraction are not smooth enough, and the design is not user-friendly enough. In addition, the elastic arm obtains a rebound force through the stop column at its bottom to make the button rebound and reset. Sometimes it will be stuck due to weak elastic force, resulting in an unsmooth reset. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a charging device for storing data cables, which has a simple structure, a more reasonable design, smoother pulling out and retracting of the data cables, a more user-friendly design, normal button reset, and smoother use.
