It should be noted that the following described embodiments and features in the embodiments can be combined with each other in the case of no conflict.

[0036] Many different implementation manners or examples are provided below to realize the structure of the utility model.

[0037] Please refer to Figures 1-7 The embodiment of the utility model is a charging wire winding device, mainly including a body 1, the body 1 is provided with a power plug 11, specifically referring to Figure 2 The power plug 11 can be a cigarette lighter plug suitable for automobile cigarette lighter socket, the power plug 11 can be connected to an automobile cigarette lighter socket to obtain power, or it can be a USB plug as shown in Figure 4 Or it can be a USB plug as shown in Figure 5The power module 2 is arranged in the body 1, which includes a motor 21, and in other embodiments, also includes a gear set 22 connected with the motor 21, which can be used to generate higher rotating torque in a deceleration manner. Of course, the gear set 22 can also be built into the motor 21, that is, the standard industrial standard common deceleration motor series. The gear set can be designed as a single-stage or multi-stage deceleration structure according to the application requirements, so that the winding process is more stable and effectively reduces the operating noise to avoid affecting the use experience of the driver or passenger. The winding module 3 includes a winding wheel 31, and the winding module 3 is connected with the power module 2 and can be driven by the power module 2 to wind the charging wire 4. The charging wire 4 can be wound on the winding wheel 31. One end of the charging wire 4 is electrically connected with the power plug 11 to provide power through the power plug 11, and the other end is provided with a charging head 6. The charging wire 4 can be wound on the winding module 3. The charging wire 4 can be provided as one or multiple to meet the charging needs of multiple mobile phones. The switch 51 can be one, which is arranged on the body 1, or arranged on the power plug 11, or arranged on the charging head 6. The switch 51 can also be provided as multiple, and multiple switches 51 can be arranged at different positions, such as two or three of the body 1, the power plug 11, or the charging head 6. The switch 51 is used to start the power module 2, and the power module 2 can drive the winding module 3 to move, thereby completing the winding of the charging wire 4. For details, see Figure 8 As shown, the charging wire is provided as two, and the winding wheel 31 can be one or two.

[0038] When the user needs to charge, just pull out the charging line 4, and then connect it to the device such as mobile phone, and after the charging is completed, the charging line 4 can be smoothly retracted through the switch 51 to drive the power module 2 to rotate the winding wheel 31, which not only ensures the neatness of the car, but also improves the service life and safety. Through the power driven mode, the charging device itself is cleverly used to bring the characteristics of the charging device itself, completely replacing the traditional spring mechanism, and there is no problem of affecting the winding effect and the charging line cannot be smoothly positioned or recycled due to spring fatigue and the like. Since there is no spring to accumulate tension, the problem of pulling out the entire charger from the charging hole will not occur when pulling out the charging line; the winding wheel 31 in the winding module 3 can be closely matched with the power module 2 to ensure that the charging line is evenly arranged during winding to avoid winding or jamming, thereby improving the durability and service life of the device. The user can control the winding function through the switch 51, which can be arranged on the body 1 or / and the power plug 11 or / and the charging head 6, and can be designed as one or more according to different application requirements, providing a more flexible and intuitive operation mode to adapt to different vehicles and user habits. The switch 51 can be a physical switch, a touch switch, or an induction switch.

[0039] Specifically referring to Figure 6 As shown in the figure, the winding module 3 further comprises a conductive slip ring 32, the A end of the conductive slip ring 31 is connected with the charging line 4, and the B end is connected with the power plug 11, and the power plug 11 and the charging line 4 are electrically connected through the conductive slip ring 32. Thus, when the winding wheel 31 rotates, the power plug 11 remains stationary and can be stably connected with the car cigarette lighter socket, and the charging line 4 rotates with the winding wheel 31 but can always maintain electrical connection with the power plug 11, thereby achieving stable electrical connection between the charging line 4 and the power plug 11 when the winding wheel 31 rotates. The internal structure of the conductive slip ring is known technology, which will not be described here.

[0040] In some embodiments of the utility model, one-way bearing is arranged between the winding wheel 31 and the motor 21; in other embodiments, ratchet structure can also be arranged between the winding wheel 31 and the motor 21. As shown in the figure, Figure 7 The winding wheel 31 is provided with a rotating groove 311, and a plurality of one-way hook grooves 312 are arranged on the groove wall of the rotating groove 311, and the rotating shaft of the motor 21 can be connected with a ratchet (not shown) after penetrating through the winding wheel 31, so that the winding wheel 31 can only rotate in one direction relative to the motor 21, that is, through the structure, when the charging line 4 needs to be pulled out, the rotating shaft of the winding wheel 31 and the motor 21 will not be linked, so that the charging line 4 is pulled out more easily, and the operation feels better; when winding, the motor 21 can drive the winding wheel 31 to rotate, thereby completing the winding of the charging line.

[0041] To enhance intelligence and safety, the device described in this embodiment further includes a detection module. This detection module detects whether the charging head 6 is connected to an external charging device, such as a mobile phone. The detection module is electrically connected to the control module 5, which controls the operation of the power module 2. For example, when the detection module detects that the charging head 6 is not connected to a mobile phone or other device, it sends a signal to the control module 5, which then automatically activates the power module 2 to wind the charging cable 4 onto the reel 31. Specifically, in some embodiments, the detection module can be a microswitch on the charging head 6. When the charging head 6 is plugged into the mobile phone charging port, the charging cable 4 remains pulled out for charging. When the mobile phone is detached from the charging head 6, the microswitch is triggered, and the control module 5 controls the power module 2 to automatically wind up the charging cable 4. In other embodiments, the detection module can also be a module that detects the connection impedance of the charging head 6. The connection impedance of the charging head 6 differs when a mobile phone is connected and when it is not.

[0042] In some embodiments of this invention, to enhance automation, a time module is connected to the control module 5, enabling it to set an automatic winding time. When it detects that the charging head 6 is not connected to any device and the preset time has elapsed, the control module 5 will control the power module 2 to automatically perform the winding function, ensuring that the charging cable 4 remains tidy when idle, avoiding the inconvenience caused by messy cables inside the vehicle. This design not only improves the user experience but also effectively reduces the risk of damage to the charging cable 4 due to prolonged exposure.

[0043] In some embodiments of this utility model, the control module 5 is connected to a tension detection module. The tension detection module can be set at the position of the winding wheel 31 to detect the tension or torque received by the winding wheel 31. When the charging cable is wound up, if abnormal resistance or pulling is detected, the device will automatically adjust the winding speed or pause the power output to prevent the charging cable from being damaged due to excessive pulling and improve the overall service life.

[0044] In addition, a battery 33 can also be installed inside the main body 1. The battery 33 is a rechargeable battery. The battery 33 is electrically connected to the power module 2 and / or the charging head 6. When the vehicle is turned off or the vehicle's cigarette lighter socket is unplugged, the power module 2 can still be powered to continue operating to complete the winding of the charging cable 4. It can also provide a short-term emergency charging function for mobile phones when necessary.

[0045] like Figure 4 As shown, the device can also be equipped with an indicator module 34 on the main body 1. The indicator module 34 can be composed of an indicator light, a display, or a speaker or a combination thereof, to provide prompts on the operating status with light, graphics, or sound, such as displaying charging status, progress and completion of cable winding operation, or low battery warning, so as to improve the user's ease of operation and the intuitiveness of the device.

[0046] Overall, the present application overcomes the shortcomings of the traditional clockwork mechanism by the driving mode of the power module 2, provides a more stable winding experience, and improves the cleanliness and convenience of the vehicle environment.

[0047] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present application.
