Description

Technical Field

[0001] This utility model relates to the field of data cable device technology, and in particular to a retractable data cable device. Background Technology

[0002] Because ordinary data cables are generally long and inconvenient to carry, they are prone to tangling with themselves and other items if placed directly on a table or in a bag, causing inconvenience to users. To address this, retractable data cables were invented. These cables use a spring-loaded mechanism (a spiral spring) in the main body, working with a reel to form a winding module, achieving a more compact and tangle-free design. However, current retractable data cables on the market have the following problems: First, they typically only offer the function of charging a phone, making their functionality relatively limited. Some retractable data cables also include wireless charging, but the use of an adapter plate for input and output makes the structure complex. Second, the connector at the movable end hangs outside the casing after the cable is retracted, which is not only unsightly and takes up a lot of space, but the protruding metal connector can also damage other items. Third, some retractable data cables have suction cups on the bottom of the casing, which hold the cable in place when the movable end is pulled out, allowing for one-handed operation and improving ease of use. However, suction cups can only adhere to smooth surfaces and have poor stability and a short lifespan. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a multifunctional retractable data cable device with a simpler structure, a more reasonable design, the ability to charge via wires or wirelessly, the ability to neatly store the connector at the movable end, a more stable fixation, and a longer service life.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a multifunctional retractable data cable device, including a housing, a wireless charging module, a winding module, and a data cable. The wireless charging module and the winding module are installed in the housing, and a wireless charging area is provided on the housing aligned with the position of the wireless charging module. The data cable includes a first wire and a second wire. The first wire is connected to a first connector, and the second wire is connected to a second connector. Both the first connector and the second connector are located outside the housing. At least the second wire is wound around the winding module and led out from the housing to form a rotary retractable structure. The first wire and the second wire are respectively connected to the wireless charging module, forming a transfer structure between the first wire and the second wire through the wireless charging module. A rotatable magnetic chuck is provided at the bottom of the housing through a rotating shaft. A fixing magnet is provided in the magnetic chuck, and magnetic fixation is achieved by the magnetic chuck cooperating with a double-sided adhesive iron sheet.

[0005] Furthermore, a storage magnet is provided in the housing, and a magnetic attraction component that can attract the storage magnet is provided in the second connector. After the second wire is retracted, the storage magnet attracts and fixes the second connector.

[0006] Furthermore, the housing includes an outer shell, a front cover, and a rear cover, with the front cover and rear cover respectively installed at the front and rear ends of the outer shell, a wireless charging area located at the top of the outer shell, and a magnetic chuck installed at the bottom of the outer shell.

[0007] Furthermore, a storage area is provided on the front cover, and a magnet is placed on the back of the front cover and aligned with the storage area; a first wire is led out from the rear cover, a second wire is led out from the front cover, and a second connector is attached to the storage area.

[0008] Furthermore, a spring and a ball are provided at the bottom of the outer casing, with the ball resting on the bottom end of the spring; several positioning grooves are provided on the magnetic chuck, forming a ring shape. When the magnetic chuck is rotated, the spring presses the ball into any positioning groove to achieve positioning of the entire device.

[0009] Furthermore, the first wire includes one wire, and the second wire includes one, two, or three wires, with each second wire connected to a second connector.

[0010] Furthermore, when the number of the second connectors is greater than one, each second connector may be of the same or different interface types.

[0011] This invention combines a cable winding module and a wireless charging module, with the input and output ends of the data cable connected via the circuit board of the wireless charging module. This not only enables wireless charging of the retractable data cable but also eliminates the need for an additional adapter, simplifying the structure. The use of magnets to hold the movable connector makes the structure more compact, preventing the connector from becoming tangled and scratching other objects. Furthermore, a rotatable magnetic chuck at the bottom of the device, used with a metal plate for secure fixation, stably holds the device on rough surfaces, increasing its applicability and stability. The combination of a ball bearing and spring with a positioning groove not only helps maintain the device's orientation but also produces a rhythmic clicking sound during rotation, providing a degree of pressure relief.

The first wire 51 is connected to a first connector (not shown), and the second wire 53 is connected to a second connector 52. Both the first connector and the second connector 52 are located outside the housing. The second wire 53 is wound around the winding module 6 and led out from the housing. The device forms a rotating and telescopic structure (either the first wire 51 and the second wire 53 are both telescopic, or only the second wire 53 is telescopic); the first wire 51 and the second wire 53 are respectively connected to the wireless charging module 4, forming a transfer structure between the first wire 51 and the second wire 53 through the wireless charging module 4; a rotatable magnetic chuck 3 is provided at the bottom of the housing via a pivot, and a fixing magnet 31 is provided in the magnetic chuck 3.
