[0026] Please see below. Figures 1-6 The electric telescopic cable device provided in this embodiment of the utility model specifically includes: The outer casing 10 has an internal mounting cavity and a wire outlet hole 11 on its surface. The drive unit 20 is installed in the mounting cavity; Turntable 30 is connected to drive unit 20 via transmission; The first motherboard 41 is fixed to the turntable 30 and rotates synchronously with the turntable 30. The first motherboard 41 is provided with a contact 411. The second motherboard 42 is disposed opposite to the first motherboard 41. The second motherboard 42 is provided with a conductive part that makes sliding electrical contact with the contact 411. The second motherboard 42 is connected to an external power source. The data cable 43 has one end connected to the turntable 30 and electrically connected to the first motherboard 41, and the other end passes through the cable outlet 11 and extends out or retracts into the mounting cavity as the turntable 30 rotates. The drive unit 20 is electrically connected to the second motherboard 42.

[0027] In this embodiment, the drive unit 20 drives the turntable 30 and the first motherboard 41 to rotate, and the sliding electrical contact between the first motherboard 41 and the second motherboard 42 is used to achieve stable power supply. The motor drive replaces the traditional mechanical spring, providing strong and controllable winding and unwinding force, effectively overcoming the limitations of traditional solutions on cable material, thickness or length. It can stably wind and unwind thicker, stiffer or longer high-power data cables, thereby solving the problems of data cable rebound jamming and insufficient tension.

[0028] Meanwhile, this embodiment adopts a sliding electrical contact structure, which improves the reliability of the power transmission structure, avoids the defects of traditional power transmission structures such as easy wear and unstable connection, and solves the problem of attenuation after repeated use of traditional mechanical springs, thus significantly improving the power supply reliability and device lifespan.

[0029] Based on this, the present invention can realize automatic data cable retraction and extension, which is convenient to operate and solves the problem of messy cable tangling, thereby improving the user's storage efficiency and user experience.

[0030] Understandably, in specific application scenarios, the turntable 30 is driven by the drive unit 20 to rotate in the forward or reverse direction, and the data cable 43 follows the rotation of the turntable 30 and is wound or released around the turntable 30 to achieve automatic extension and retraction function.

[0031] In specific application scenarios, the outer shell 10 includes an upper shell 13 and a lower shell 14, which are fastened together to form an installation cavity. The upper shell 13 is provided with structures such as a wire outlet hole 11, while the lower shell 14 is provided with various installation structures for installing various components, including the drive unit 20.

[0032] In one embodiment, the electric telescopic cable device provided by this utility model further includes a drive shaft 51, a drive unit 20 is connected to the drive shaft 51, and a turntable 30 is connected to the drive shaft 51 and rotates synchronously with the drive shaft 51.

[0033] In this embodiment, by setting the drive shaft 51 as a power transmission medium, the turntable 30 is connected to the drive shaft 51, thereby stably transmitting the power of the drive unit 20 to the turntable 30, so that the turntable 30 rotates synchronously with the drive shaft 51, which can improve the smoothness and reliability of the transmission.

[0034] In another embodiment, the electric telescopic cable device provided by this utility model further includes a gear set 52, which includes at least one gear. The gear set 52 is connected to the drive unit 20 for driving the turntable 30 to rotate under the drive of the drive unit 20.

[0035] In this embodiment, by setting the gear set 52 as a transmission mechanism, the power of the drive unit 20 is transmitted to the turntable 30 through the gear set 52, thereby improving the stability and controllability of the turntable 30 rotation. The transmission ratio of the gear set 52 can be adjusted according to different needs to achieve optimized matching of the turntable 30 speed and torque, thereby further improving the response speed and running smoothness of the data cable 43 during the winding and unwinding process.

[0036] In addition, in other embodiments, the drive shaft 51 and the gear can be combined to form a composite transmission structure, and the power can be transmitted to each transmission component in the electric telescopic cable device through the composite transmission structure to adapt to the structural requirements of different application scenarios, improve the overall transmission efficiency and system adaptability, and achieve more efficient torque transmission and speed regulation.

[0037] For example, when the drive unit 20 is a motor, the motor can be arranged laterally to save space, and a worm gear can be installed at the motor output end. The transmission shaft 51 and the gear can be integrated, that is, the gear can be set on the outer periphery of one end of the transmission shaft 51 and fixedly connected to it coaxially, while the other end can be connected to the turntable 30, forming a worm gear meshing transmission structure. This can improve space utilization and structural compactness, while the self-locking characteristic of the worm gear transmission can effectively prevent the turntable 30 from rotating in the opposite direction when there is no power input. This can effectively avoid the problem of abnormal extension or retraction of the data cable due to external force, further improving the stability and safety of the device operation, thereby enhancing the controllability of the retraction and extension process. For another example, the motor can also be arranged vertically on the side of the mounting cavity, and a driving gear can be set at the motor output end and a driven gear can be set on the outer periphery of the turntable 30, so that the driving gear and the driven gear mesh and transmit power directly to the turntable 30.

[0038] In specific application scenarios, the arrangement and connection relationship of the drive unit 20, turntable 30, transmission shaft 51 and / or gear set 52 can be flexibly selected according to the spatial layout of the device and the transmission requirements, so as to achieve both structural compactness and transmission efficiency.

[0039] In a specific embodiment, in order to keep the data cable 43 neat and orderly when it is wound into the mounting cavity, a winding shell can also be provided in the mounting cavity. The upper winding shell 81 and the lower winding shell 82 are fastened together to form a winding cavity. The side of the winding shell is provided with a wire hole for the data cable 43 to pass through. The upper winding shell 81 and the lower winding shell 82 are respectively provided with through holes for the drive shaft 51 or other components to pass through, so as to achieve the functions of fixed connection or transmission connection.

[0040] In one embodiment, the electric telescopic cable device provided by this utility model further includes a guide structure 60 disposed at the extension or retraction path of the data cable 43. The guide structure 60 includes at least two guide members disposed opposite to each other, and a clamping gap is formed between the two guide members for the data cable 43 to pass through.

[0041] In this embodiment, by setting the guide structure 60, the winding and unwinding path of the data cable 43 can be effectively guided and limited, ensuring that the data cable 43 moves along a predetermined trajectory during extension and rewinding, avoiding deviation, tangling, or jamming. It is understood that the shape of the guide is adapted to the outer diameter of the data cable 43 to reduce friction or damage to the data cable and ensure stable sliding of the data cable 43 during high-speed winding and unwinding. Furthermore, the surface of the guide can be made of soft surfaces such as silicone or TPE, or materials in the form of plush or fabric, to provide a certain amount of friction to propel the data cable to roll.

[0042] In one embodiment, the guide is a rotatable first clamping roller and a second clamping roller; wherein the first clamping roller is connected to the drive unit 20 and is driven to rotate by the drive unit 20.

[0043] In this embodiment, the first clamping roller is connected to the drive unit 20 via a transmission mechanism and is powered by the drive unit 20 to rotate synchronously. The second clamping roller can rotate freely, and the two work together to form a clamping traction structure. In a specific application scenario, when the data cable 43 is being wound up or down, the first clamping roller rotates in both directions under the power, directly acting on the outer surface of the data cable 43 to achieve active conveying and winding. The second clamping roller rotates synchronously under the action of friction, effectively clamping and guiding the data cable 43, thereby ensuring that the data cable 43 is subjected to uniform force and runs smoothly during the winding up or down process.

[0044] In a specific implementation, the drive unit 20 is connected to the first and second clamping rollers via a transmission connection. For example, when the drive shaft 51 and gear are integrated, a matching rotating shaft and corresponding gear can also be provided, and the clamping rollers can be mounted on the rotating shaft. Based on this, when the drive unit 20 drives the turntable 30 to rotate via the drive shaft 51 to wind or unwind the data cable 43, power is synchronously transmitted to the rotating shaft via the gear, thereby driving the clamping rollers to rotate synchronously. This coordinates with the turntable 30's movement to achieve the coordinated winding and unwinding of the data cable 43, effectively improving transmission efficiency and action consistency. It is understood that the direction in which the clamping rollers drive the data cable winding and unwinding is always consistent with the direction of the turntable 30, ensuring that the data cable 43 experiences continuous force and no twisting during extension or retraction. Of course, depending on the actual situation, the clamping rollers can also be directly connected to the drive unit 20 via a transmission connection, directly transmitting the power of the drive unit 20 to the clamping rollers to make them rotate.

[0045] In addition, in another specific implementation case, a separate drive unit can be added specifically for driving the clamping roller to rotate, thereby distinguishing the drive unit for driving the turntable from the drive unit for driving the clamping roller.

[0046] In other embodiments, at least one guide member can be movably or flexibly configured. By making at least one guide member movably or flexibly connected, the clamping gap can be automatically adjusted according to changes in the diameter of the data cable or positional offset during the winding and unwinding process, thereby accommodating data cables of different specifications.

[0047] In one embodiment, the electric retractable cable device provided by this utility model further includes a winding unit 70. One end of the winding unit 70 is coaxially arranged with the turntable 30, and the other end is exposed outside the housing 10. It is used to manually drive the turntable 30 to rotate to extend or retract the data cable 43.

[0048] In this embodiment, by setting up the winding unit 70, the user can manually rotate the exposed end to retract the data cable 43 in the event of a power outage or emergency, without relying on power to complete the use and storage of the data cable 43, thus improving the operational flexibility of the device.

[0049] In specific application scenarios, a through hole can be provided between the first motherboard 41 and the second motherboard 42, and the through hole can be aligned with the turntable 30 or the drive shaft 51. One end of the winding unit 70 passes through the through hole and is fixedly connected to the turntable 30 or the drive shaft 51, while the other end extends to the outside of the housing 10, forming an exposed operating part (e.g., a knob). When the user needs to operate manually, the exposed knob can be rotated directly, and the turntable 30 will be rotated through the transmission structure to realize the winding and unwinding of the data cable 43. In addition, the winding unit 70 can also be provided on the side. A gear transmission structure can be provided at the end of the winding unit 70 and meshed with the corresponding gear on the turntable 30 or the drive shaft 51 to realize power transmission.

[0050] In one embodiment, the contact 411 includes at least two sets of contact springs, each set of contact springs being evenly distributed along the circumference of the first main board 41 and maintaining sliding contact with the conductive part.

[0051] In this embodiment, by setting multiple sets of contact springs evenly distributed circumferentially, stable sliding contact with the conductive parts is ensured at all times. This allows the first main board 41 and the second main board 42 to maintain a stable electrical connection when rotating relative to each other, effectively preventing signal interruption or poor contact. The specific number of contact springs can be set according to actual needs, for example, three or four sets can be set to enhance conductivity stability and load-bearing capacity, while improving the reliability and durability of data transmission.

[0052] It is understandable that contact springs are made of highly elastic conductive materials to enhance contact conductivity, such as using metal contact elements 411 as springs.

[0053] In one embodiment, a fixing structure 12 is provided on the outer surface of the housing 10 for fixing the end of the stored data cable 43.

[0054] In this embodiment, by providing a fixing structure 12 on the outside of the outer casing 10, the end of the data cable 43 can be securely locked after it is fully wound up, preventing the cable from loosening or unraveling due to shaking or external force, thus maintaining the neatness and stability of the stored state. The fixing structure 12 can be a buckle, a slot, a magnetic component, Velcro, or other form, which can be flexibly selected according to actual usage requirements.

[0055] For example, a combination of magnetic components and snap-fit ​​devices can be used. A slot for the end of the data cable 43 can be provided on the outside of the outer shell 10, and a corresponding protrusion or latch can be provided on the end of the data cable 43. When the data cable 43 is wound up, the end can be inserted into the slot to achieve fixation. At the same time, a magnetic component is provided on the inside of the slot to form a magnetic attraction with the metal part at the end of the data cable 43, further enhancing the reliability of fixation and the portability of storage.

[0056] In one embodiment, the electric retractable cord device provided by this utility model further includes an electronic control component electrically connected to the second main board 42. The electronic control component includes a switching unit, a sensing unit, and a control unit disposed on the surface of the housing 10 or the second main board 42. The switching unit and the sensing unit are used to acquire switching commands and external sensing signals, and transmit the signals to the control unit; the control unit is used to generate control commands based on the signals to start and stop the drive unit 20, so as to realize the automatic extension and retraction of the data line 43.

[0057] In this embodiment, by setting the switch unit and the sensing unit to work together, user operation commands and external environmental signals are collected in real time. The control unit generates corresponding control commands according to the commands or signals, thereby controlling the drive unit 20 to drive the extension and retraction of the data line 43, so as to realize automated operation.

[0058] In a specific embodiment, the switching unit may be one or more of a push-button switch, rotary switch, touch switch, and voice-activated switch; the sensing unit may be one or more of a thermal sensor, infrared sensor, human body sensor, current sensor, and near-field communicator.

[0059] Users can manually send extension commands by pressing the button or triggering the touch switch, or they can use the voice control switch for voice operation, improving ease of use. Simultaneously, the sensing unit can detect changes in the surrounding environment in real time, generating sensing signals to the control unit accordingly. For example, it can automatically activate when a human body sensor detects a user approaching, or trigger the extension of the data cable 43 when the device is connected, or automatically trigger a rewind command when the current sensor detects the user unplugging the data cable 43 from charging. The drive unit 20 then activates to automatically retract the data cable 43 into the housing 10.

[0060] Of course, in other embodiments, other switching forms or sensing methods can be set according to actual needs.

[0061] In one embodiment, a take-up / reel switch is provided at one end of the data cable 43 exposed outside the housing 10. The take-up / reel switch is electrically connected to the drive unit 20 and is used to control the drive unit 20 to drive the data cable 43 to extend or retract.

[0062] In this embodiment, the retractable cable switch can be integrated near the plug of the data cable 43, allowing users to operate it directly after inserting the device without touching the main body of the housing 10. For example, the retractable cable switch can be electrically connected to the drive unit 20. When the user unplugs the data cable 43 from the device after charging, triggering the retractable cable switch will automatically trigger the drive unit 20 to retract the data cable 43 into the housing 10, achieving a convenient "use and retract" experience without requiring the user to manually operate the control components on the housing 10.

[0063] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the systems disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the descriptions are relatively simple; relevant parts can be referred to in the method section.
