In some embodiments of the present application, the telescopic cable module 1 can be used directly as a separate component to be attached to an electronic device such as a mobile power supply, adapter, or power strip. The telescopic cable module 1 can also be a component within the electronic device; this is not limited by the embodiments of the present application. In some embodiments of the present application, the telescopic cable module 1 can include the cable 11 (i.e., the data cable). The cable 11 can serve to connect the charging interface.

The winding section 131 can serve to wind up the cable 11.The first positioning section 132 can serve to fasten the coil spring 16. The second positioning section 133 can position the wheel 13 and enable it to rotate. Of course, the wheel 13 can also include other sections, for example, the damping engagement section, etc., and this is not limited by the embodiments of the present application. Based on this, the cable 11 can also be connected to the wheel 13. Here, the cable 11 can be connected to the coiling section 131 of the wheel 13. The cable 11 can be connected to the first positioning section 132 of the wheel 13. The cable 11 can be connected to the second positioning section 133 of the wheel 13, etc., and this is also not limited by the embodiments of the present application. With reference to Figures 3, 18, and 19, the cable 11 can be connected to the wheel 13 in some embodiments of the present application. This means that a part of the cable 11 is connected to the wheel 13. For example, this part is one end of the cable 11, with the other part of the cable 11 being wound around or unwound from the wheel 13. Furthermore, the cable 11 can be permanently connected to the wheel 13. For example, the cable 11 is glued to the wheel 13, or, for example, the cable 11 is welded to the wheel 13. Or the cable 11 can be detachably connected to the wheel 13. For example, the cable 11 is screwed to the wheel 13, or, for example, the cable 11 is snap-fitted to the wheel 13, the possibilities of which are not limited by the embodiments of the present application.In some embodiments of the present application, the induction element 135 is arranged on the wheel 13. The induction element 135 can be arranged on the winding section 131 of the wheel 13, the induction element 135 can be arranged on the first positioning section 132 of the wheel 13, the induction element 135 can be arranged on the second positioning section 133 of the wheel 13, and of course the induction element 135 can also be arranged on other parts of the wheel 13, and this is not limited by the embodiments of the present application. In some embodiments of the present application, the induction element 135 is arranged on the wheel 13 and serves, when the cable 11 is unwound from the wheel 13, to interact with a corresponding triggering element 142 to enable the control module to receive the unwinding signal of the cable 11. The method of interaction between the induction element 135 and the corresponding triggering element 142 can be the Hall induction method; for example, the induction element 135 is a magnet and the triggering element 142 is a Hall effect sensor. The telescopic cable module 1 receives an external power supply, for example, a portable power supply or an adapter. At this point, the magnet generates a magnetic field under the influence of the power supply, the Hall effect sensor generates a Hall effect signal under the influence of the magnetic field, and the control module receives the Hall effect signal to obtain the unwinding signal of the cable 11.Of course, the method of interaction of the induction element 135 with the corresponding triggering element 142 can also be a different method, for example, the induction element 135 is a first induction magnet and the triggering element 142 is a second induction magnet, wherein the first induction magnet and the second induction magnet magnetically repel each other, the first induction magnet drives the second induction magnet to a movement along the direction away from the first induction magnet, and the control module receives the drive signal of the movement of the second induction magnet in order to obtain the unwinding signal of the cable 11. In some embodiments of the present application, the induction element 135 is arranged on the wheel 13 and serves, when the cable 11 is unwound from the wheel 13, to interact with the corresponding release element 142 to enable the control module to receive the unwinding signal of the cable 11. The unwinding signal of the cable 11 can comprise an optical signal, an electrical signal, an acoustic signal, etc., and this is not limited by some embodiments of the present application. In some embodiments of the present application, the induction element 135 is arranged on the wheel 13 and serves, when the cable 11 is unwound from the wheel 13, to interact with the corresponding triggering element 142 to enable the control module to receive the unwinding signal of the cable 11. The unwinding signal of the cable 11 can characterize the current state information of the cable 11, for example, the current unwound length of the cable 11; furthermore, for example, the current unwound extent of the cable 11; or, for example, the current current and voltage, etc., passing through the cable 11. This is not limited by some embodiments of the present application. In the telescopic cable module 1, provided by some embodiments of the present application, the cable 11 can be wound around or unwound from the wheel 13, since the cable 11 is connected to the wheel 13, the induction element 135 is arranged on the wheel 13, and the induction element 135, when the cable 11 is unwound from the wheel 13, can interact with the corresponding triggering element 142 to enable the control module to receive the unwinding signal of the cable 11. This allows the user to intuitively obtain the current status information of the cable 11 via the unwinding signal, for example, the unwound length of the cable 11, and also, for example, the unwound extent of the cable 11, etc.; the user can perform an adaptive adjustment based on the current state information of cable 11, for example, by receiving the current state information of cable 11, determine that the length of cable 11 unwound from the wheel is insufficient and that cable 11 needs to be unwound further, etc., thereby improving the user experience.In contrast to the prior art, in which the user cannot receive the unwinding signal of the cable 11 of the telescopic cable module 1, leading to a technical problem of a poorer user experience, the present application, through the arrangement of the induction element 135 and furthermore the arrangement of the induction element 135 on the wheel 13, which serves to interact with the corresponding release element 142 in the event that the cable 11 is unwound from the wheel 13, in order to enable the control module to receive the unwinding signal of the cable 11, has the technical effect that it is possible, through the interaction of the induction element 135 with the corresponding release element 142, to enable the control module to receive the unwinding signal of the cable 11 in order to improve the user experience. With reference to Fig. 3, Fig. 4 and Fig. 5, a telescopic cable module 1 is provided by some embodiments of the present application, wherein one of the induction element 135 and the release element 142 is a magnet and the other is a Hall element.

Here, the induction element 135 can be the magnet and the triggering element 142 the Hall element; or the induction element 135 is the Hall element and the triggering element 142 the magnet. This is not limited by some embodiments of the present application. Specifically, the telescopic cable module 1 receives an external power supply, for example a mobile power supply or an adapter. At this point, the magnet generates a magnetic field under the influence of the power supply, the Hall element generates a Hall signal under the influence of the magnetic field, and the control module receives the Hall signal to obtain the unwinding signal of the cable 11. The telescopic cable module 1, which is provided by some embodiments of the present application, has the central advantages of high magnetic field detection strength, contactless operation, high precision and durability, etc., by setting one of the induction element 135 and the triggering element 142 as a magnet and the other as a Hall element, and by the magnet inducing the Hall element to enable the Hall element to generate the Hall signal.

In some embodiments of the present application, the telescopic cable module 1 may further comprise the stationary release circuit board 14. The stationary release circuit board 14 may be a printed circuit board (PCB); naturally, the stationary release circuit board 14 may also be a flexible printed circuit board (FPC); the stationary release circuit board 14 may also be a rigid-flexible circuit board (soft and hard combination plate), and this is not limited by the embodiments of the present application. It should be explained that the rigid-flexible circuit board is a circuit board that exhibits the properties of both the flexible circuit board and the printed circuit board, since the flexible circuit board and the printed circuit board are combined by a process such as pressing in accordance with relevant technical requirements.In some embodiments, the stationary trigger circuit board 14 can also be a structure serving for current conduction and can therefore also be referred to as a conductive element. In some embodiments of the present application, the stationary release circuit board 14 can comprise the first stationary end 141 and the release element 142. The first stationary end 141 and the second movable end 151 are rotatably connected.

In some embodiments, the data cable A30 can be released from the coil disk A20 or wound around the coil disk A20 to further adjust the length of the data cable A30. In some embodiments, one end of the data cable A30 can be electrically connected to the external device to provide an external connection, and the other end can be connected to the conductive component A40 to provide the external connection through the conductive component A40, for example, the connection to the main body A101.

In some embodiments, the rotary shaft A111 can define the axis of rotation. Referring to Figures 23 and 24, the coil disc A20 can have a disc-shaped or plate-shaped structure and can be made of a hard material. The coil disc A20 can be rotatably connected to the installation housing A10, for example, the first housing A11 and / or the second housing A12. In some embodiments, the coil disc A20 can be mounted on the rotating shaft A111 to be rotatably connected to the installation housing A10, for example, the first housing A11 and / or the second housing A12. Of course, the method of rotatable connection of the coil disc A20 to the installation housing A10, for example, the first housing A11 and / or the second housing A12, need not be limited to the rotating shaft A111, but can also be another method, even one known to those skilled in the art, for example, bearings, balls, etc., which can still define the axis of rotation.In some scenarios, the coil disc A20 can be passed through a hole or slot in the installation housing A10, for example, the first housing A11 and / or the second housing A12, to create the rotary connection. In some scenarios, the coil disc A20 can be rotatably connected to the rotary shaft A111. In some embodiments, the spool disk A20 can be configured using the wheel 13 in the above embodiments. In some embodiments, the spool disk A20 can be the wheel 13 in the above embodiments. Referring to Figures 22, 23, and 24, the conductive component A40 can comprise a stationary conductive component A41, which is arranged on the installation housing A10, for example, the second housing A12, and a moving conductive component A42, which is arranged on the coil disk A20. The stationary conductive component A41 and the moving conductive component A42 are electrically connected; the stationary conductive component A41 can be electrically connected to the main body A101; the moving conductive component A42 can be electrically connected to the data cable A30, whereby the main body A101, the stationary conductive component A41, the moving conductive component A42, and the data cable A30 can be electrically connected sequentially.The arrangement of the stationary conductive component A41 and the moving conductive component A42 can establish the electrical connection between the main body A101 and the data cable A30 in the state where the installation housing A10 and the coil disk A20 are rotating relative to each other, and can also establish the electrical connection in the state where the installation housing A10 and the coil disk A20 are at rest relative to each other. In further embodiments, the arrangement in which the main body A101, the stationary conductive component A41, the moving conductive component A42, and the data cable A30 are electrically connected sequentially can facilitate the power supply (including charging) and / or data transmission. In some embodiments, the conductive component A40 can comprise the stationary release circuit board 14 and the moving circuit board 15 in the above embodiments. In some embodiments, the stationary conductive component A41 can be configured using the stationary release circuit board 14 in the above embodiments. In some embodiments, the stationary conductive component A41 can be the stationary release circuit board 14 in the above embodiments. In some embodiments, the moving conductive component A42 can be configured using the moving circuit board 15 in the above embodiments. In some embodiments, the moving conductive component A42 can be the moving circuit board 15 in the above embodiments. In some embodiments, the data cable module A102 can be connected externally via an end of the data cable A30 that is not connected to the moving conductive component A42, and can be connected externally via the moving conductive component A42, for example, by being electrically connected to another electronic device. In some embodiments, the data cable module A102 can be connected externally by the interaction of the moving conductive component A42 with the stationary conductive component A41, for example, by being electrically connected to the main body A101. In some embodiments, when the coil disk A20 rotates relative to the installation housing A10, for example, the second housing A12, it can rotate about the axis of rotation, causing the moving conductive component A42 to rotate relative to the stationary conductive component A41 and also about the axis of rotation. This results in the main body A101, the stationary conductive component A41, the moving conductive component A42, and the data cable A30 being electrically connected sequentially. Simultaneously, the stationary conductive component A41, in the state of interaction with the moving conductive component A42, outputs the electrical signal indicating the cable movement. In further embodiments, the stationary conductive component A41 can output the electrical signal indicating the cable movement as far as the main body A101 or to the device electrically connected to the stationary conductive component A41.In some embodiments, the device electrically connected to the stationary conductive component A41 can also be arranged on the data cable module A102, or even be part of the data cable module A102. That is, the data cable module A102 can receive the electrical signal indicating cable movement in order to implement the function of the device electrically connected to the stationary conductive component A41. It is understandable that the circuit for outputting the electrical signal indicating cable movement may be different from the circuit for power supply (including charging) and / or data transmission; that is, the electrical signal indicating cable movement is not transmitted by the circuit for power supply (including charging) and / or data transmission. In some embodiments, the electrical signal may be the unwinding signal in the embodiments described above. In some embodiments, the optical signal, the acoustic signal, etc., in the embodiments described above may be converted into the electrical signal described above for output and may be output to the main body A101, to the device electrically connected to the stationary conductive component A41, or to the data cable module A20. Furthermore, the cable movement is closely related to the direction of rotation of the coil disk A20, meaning that if the electrical signal can indicate the cable movement, it can also indicate the direction of rotation. In some embodiments, the direction of rotation can include a first direction of rotation, in which the spool disk A20 winds the data cable A30, and a second direction of rotation, in which the spool disk A20 unwinds the data cable A30. That is, the first direction of rotation corresponds to the cable winding movement, and the second direction of rotation corresponds to the cable unwinding movement. Furthermore, in other embodiments, the electrical signal indicating the cable retraction movement can simultaneously indicate the first direction of rotation. Furthermore, in other embodiments, the electrical signal indicating the cable withdrawal movement can simultaneously indicate the second direction of rotation. In some embodiments, the main body A101 or the device electrically connected to the stationary conductive component A41 can generate a movement command corresponding to the cable movement in response to the electrical signal in order to control the electronic device A100, for example the data cable module A102. In some embodiments, the main body A101 can generate a movement command corresponding to the cable movement in response to the electrical signal, in order to control the electronic device A100. In some embodiments, the main body A101 can generate a movement command corresponding to the cable retraction movement, in order to control the electronic device A100 to switch off. In some embodiments, the main body A101 can generate a movement command corresponding to the cable extension movement, in order to control the electronic device A100 to display the battery level. In some embodiments, the data cable module A102 or the main body A101 serves to generate a first movement command corresponding to the cable retraction movement, based on the electrical signal, and / or to generate a second movement command corresponding to the cable extension movement, also based on the electrical signal. The main body A101 can be controlled by the first movement command and / or the second movement command. In some embodiments, the main body A101 can be used to execute the first movement command to control the electronic device A100 to switch off. In some embodiments, the main body A101 can be used to execute the second movement command to control the electronic device A100 for displaying the battery level. In some embodiments, the stationary conductive component A41 can be part of the installation housing A10, for example, the second housing A12, which means it can also be replaced by other structures on the installation housing A10, for example, the second housing A12, to realize the function of the stationary conductive component A41. In some embodiments, the moving conductive component A42 can be part of the coil disk A20, which means it can also be replaced by other structures on the coil disk A20 to realize the function of the moving conductive component A42. In some embodiments, the stationary conductive component A41 and the moving conductive component A42 can be arranged along the axis of rotation. In some embodiments, the stationary conductive component A41 and the moving conductive component A42 can be arranged relative to each other along the axis of rotation. In some embodiments, the moving conductive component A42 can be arranged along the axis of rotation on a side of the coil disk A20 that faces the stationary conductive component A41. In some embodiments, a receiving slot A2001 can be arranged on the coil disk A20 to accommodate the moving conductive component A42. The arrangement of the receiving slot A2001 can reduce the thickness of the coil disk A20 along the axis of rotation, thereby reducing the thickness of the data cable module A102 along the axis of rotation. This allows for the miniaturization of the data cable module A102, which in turn reduces the space required in the electronic device A100, thus also enabling miniaturization of the electronic device A100. In further embodiments, at least part of the stationary conductive component A41 can also be located in the receiving slot A2001. Referring to Fig. 25, Fig. 26, Fig. 27, Fig. 28, Fig. 29 and Fig. 30, the stationary conductive component A41 can be folded down along the direction indicated by the arrow, being arranged relative to the movable conductive component A42 and being able to realize the electrical connection. The stationary conductive component A41 can comprise a conductive rail A411 and a stationary sensing component A412. The conductive rail A411 extends circumferentially around the axis of rotation and forms a ring that can be electrically connected to the moving conductive component A42 to establish the electrical connection between the stationary conductive component A41 and the moving conductive component A42, and furthermore to establish the sequential electrical connection between the main body A101, the stationary conductive component A41, the moving conductive component A42, and the data cable A30. The stationary sensing component A412 interacts with the moving conductive component A42, enabling the stationary conductive component A41 to output the electrical signal.In some embodiments, the electrical signal can be generated by the stationary sensing component A412 and output by the stationary conductive component A41, or it is transmitted by the stationary sensing component A412 via the moving conductive component A42 to the stationary conductive component A41 and output by the stationary conductive component A41. In some embodiments, the electrical signal can be transmitted by the stationary sensing component A412 and thus output by the stationary conductive component A41. In some embodiments, the stationary sensing component A412 can trigger the output of the electrical signal by the stationary conductive component A41.In some embodiments, the stationary detection component A412 can trigger the generation of the electrical signal by the moving conductive component A42 and transmit it to the stationary conductive component A41, where it is output by the stationary conductive component A41. In some embodiments, the conductive rail A411 can be configured using the first fixed end 111 in the embodiments described above. In some embodiments, the conductive rail A411 can be the first fixed end 111 in the embodiments described above. In some embodiments, the stationary detection component A412 may not be arranged on the stationary conductive component A41, but may be arranged on the installation housing A10, or even on the main body A101. The number of conductive rails A411 can be multiple, and they can be arranged one after the other in a ring around the axis of rotation, spaced apart. The number of conductive rails A411 can correspond to the number of conductors in the data cable A30 in order to realize a one-to-one electrical connection between the conductive rails A411 and the conductors in the data cable A30, wherein in further embodiments the electrical connection is realized by the moving conductive component A42. Of course, the number of conductive rails A411 can also be specially adapted based on the requirements of some scenarios, so that it does not match the number of wires in the data cable A30.

In some embodiments, the stationary detection component A412 can be configured using the triggering element 142 in the embodiments described above. In some embodiments, the stationary detection component A412 can be the triggering element 142 in the embodiments described above. The movable conductive component A42 can comprise a conductive contact A421 and a movable release component A422. The conductive contact A421 can touch the stationary conductive component A41, for example, the conductive rail A411, to establish the electrical connection. In further embodiments, the conductive contact A421 can bear elastically against the stationary conductive component A41, for example, the conductive rail A411, to establish the electrical connection. The movable release component A422 serves to interact with the stationary conductive component A41, for example, the stationary sensing component A412, whereby the stationary conductive component A41 outputs the electrical signal.This means that when the coil disk A20 and the installation housing A10, for example the second housing A12, rotate relative to each other, the stationary detection component A412 and the moving release component A422 approach each other or move away from each other, with the stationary conductive component A41 outputting the electrical signal in the state of interaction between the stationary detection component A412 and the moving release component A422.In some embodiments, the interaction of the conductive contact A421 with the stationary conductive component A41, for example the conductive rail A411, when the stationary detection component A412 and the moving trigger component A422 approach each other, can realize the electrical connection between the stationary conductive component A41 and the moving conductive component A42, and furthermore realize the successive electrical connection of the main body A101, the stationary conductive component A41, the moving conductive component A42 and the data cable A30.

In some embodiments, the conductive contact A421 can be configured using the second moving end 151 in the embodiments described above. In some embodiments, the conductive contact A421 can be the second moving end 151 in the embodiments described above. Of course, the number of conductive contacts A421 can also be specially adapted based on the requirements of some scenarios, so that it does not match the number of wires in the data cable A30 and the number of conductive rails A411. For example, several conductive contacts A421 can be connected to a conductive rail A411 to establish the electrical connection. For example, several conductive contacts A421 are electrically connected to a conductor in the data cable A30. For example, a subset of the conductive contacts A421 and a subset of the conductive rails A411 are not electrically connected to the data cable A30, i.e., they are electrically isolated, in order to transmit electrical signals between the stationary conductive component A41 and the moving conductive component A42. Furthermore, in other embodiments, a subset of the conductive contacts A421 and a subset of the conductive rails A411 interact and are electrically connected to the stationary sensing component A412 and / or the moving triggering component A422. It is understandable that the arrangement position of the conductive contact A421 can be exchanged with the arrangement position of the conductive rail A411, so that the stationary conductive component A41 and the moving conductive component A42 realize the electrical connection through the conductive contact A421 and the conductive rail A411. Furthermore, the type of realization of the electrical connection between the stationary conductive component A41 and the moving conductive component A42 cannot be limited to the interaction of the conductive contact A421 with the conductive rail A411, but the electrical connection can also be realized by other types, for example the interaction of a projection with a projection, of balls, of a projection with a sliding groove, etc., which will not be explained further. In some embodiments, the electrical signal can be generated by the moving release component A422 and transmitted by the moving conductive component A42 to the stationary conductive component A41, where it is output. In some embodiments, the electrical signal can be transmitted by the moving release component A422 to the stationary conductive component A41, where it is output. In some embodiments, the coil disk A20 generates the electrical signal, which can be transmitted via the moving release component A422 to the stationary conductive component A41, where it is output.In some embodiments, the electrical signal can be transmitted sequentially through the moving trigger component A422, the stationary sensing component A412, and then to the stationary conductive component A41. In other embodiments, the electrical signal can be transmitted sequentially through the stationary sensing component A412, the moving trigger component A422, and then via the moving conductive component A42 to the stationary conductive component A41. Finally, in some embodiments, the electrical signal can be generated by the stationary conductive component A41, for example, the stationary sensing component A412, transmitted through the moving trigger component A422, and then via the moving conductive component A42 to the stationary conductive component A41.In some embodiments, the moving trigger component A422 can trigger the generation of the electrical signal by the stationary conductive component A41, for example, the stationary sensing component A412, whereby it is output by the stationary conductive component A41. In some embodiments, the moving trigger component A422 can trigger the output of the electrical signal by the moving conductive component A42 and transmit it to the stationary conductive component A41, whereby it is output by the stationary conductive component A41. In some embodiments, the stationary detection component A412 can comprise a stationary sub-detection element A4121 electrically isolated from the data cable A30, and the moving trigger component A422 can comprise a moving sub-detection element A4221 electrically isolated from the data cable A30, wherein the stationary sub-detection element A4121 and the moving sub-detection element A4221 touch and connect electrically, or separate and the electrical connection is interrupted, when the coil disk A20 and the installation housing A10, for example the second housing A12, rotate relative to each other, wherein the stationary conductive component A411 outputs the electrical signal in the state of interaction between the stationary sub-detection element A4121 and the moving sub-detection element A4221. In some embodiments, the stationary lower detection element A4121 can generate the electrical signal by touching the moving lower detection element A4221 and thus being electrically connected to it, or it can generate the electrical signal by separating from the moving lower detection element A4221 and thus breaking the electrical connection. In some embodiments, the electrical signal can be generated based on contact and electrical connection between the stationary lower sensing element A4121 and the moving lower sensing element A4221, and output by the stationary conductive component A41. In other embodiments, the electrical signal can be generated based on separation of the stationary lower sensing element A4121 from the moving lower sensing element A4221 and interruption of the electrical connection, and output by the stationary conductive component A41. In some embodiments, a generator can be arranged inside the coil disk A20. When the coil disk A20 rotates relative to the installation housing A10, for example, the second housing A12, the generator can produce the electrical signal in response to the rotation of the coil disk A20 relative to the installation housing A10, for example, the second housing A12. The electrical signal can be transmitted by contact between the moving lower sensing element A4221 and the stationary lower sensing element A4121, and can also be output by the stationary conductive component A41.The characteristics such as positive and negative polarity, current strength (which can characterize signal strength or current magnitude), duration (duration time), and interval time between the electrical signals of the electrical signal generated by the generator can vary due to differences in cable movement. Characteristics such as positive and negative polarity, current intensity, duration, and interval between electrical signals can be modified based on the design of the coil disk A20, for example, the generator. Furthermore, cable movement can be determined based on the electrical signal. Of course, the method of generating the electrical signal by the coil disk A20 is not limited to the generator; other methods can be used to generate the electrical signal corresponding to the cable movement, thus enabling cable movement detection solely through the electrical signal. In some embodiments, an earth connection can be arranged inside the coil disk A20. The moving trigger component A422, for example, the moving lower sensing element A4221, can be grounded; that is, the moving trigger component A422, for example, the moving lower sensing element A4221, can have a level signal (which in this embodiment can also be referred to as a grounded electrical signal). The electrical signal can be transmitted by contact between the moving lower sensing element A4221 and the stationary lower sensing element A4121, and further output by the stationary conductive component A41. Characteristics such as the positive and negative polarity of the level signal, its duration (duration time), and the interval time between electrical signals can vary due to differences in cable movement.The characteristics such as positive and negative polarity, duration, and interval between the electrical signals can be modified based on the design of the moving sub-sensing element A4221 and the stationary sub-sensing element A4121. Furthermore, cable movement can be determined based on the electrical signal. Naturally, the method of generating the electrical signal by the coil disk A20 need not be limited to grounding; another method can be used to generate the electrical signal corresponding to the cable movement, thus enabling cable movement detection solely through the electrical signal. In further embodiments, the moving lower detection element A4221 has the electrical signal to output the electrical signal through the stationary lower detection element A4121 when the coil disk A20 and the installation housing A10, for example the second housing A12, rotate relative to each other. In some embodiments, the stationary lower detection element A4121 can be in permanent contact with the moving lower detection element A4221 to establish the electrical connection when the coil disk A20 and the installation housing A10, for example the second housing A12, rotate relative to each other. In some embodiments, the stationary lower sensing element A4121 and the moving lower sensing element A4221 can transition from a contact state to a non-contact state (i.e., from an electrically connected state to an electrically disconnected state), or from the non-contact state to the contact state (i.e., from the electrically disconnected state to the electrically connected state), when the coil disk A20 and the installation housing A10, for example, the second housing A12, rotate relative to each other. Furthermore, the electrical signal is associated with features such as the duration of the state, the signal strength, and / or the rule set for the state change. Additionally, the cable movement can be determined based on the electrical signal reflecting these features. For example, the order of the contact and non-contact states during cable retraction may differ from the order of the contact and non-contact states during cable withdrawal. The cable movement can be determined based on the electrical signal reflecting this difference. For example, the signal strength during cable retraction may differ from the signal strength during cable withdrawal. Based on the electrical signal reflecting this difference, the cable movement can be determined. In some embodiments, the electrical signal can be generated by the main body A101 or the data cable module A102 and transmitted via the stationary conductive component A41 to the moving conductive component A42, and then transmitted to the stationary conductive component A41 by contact between the moving sub-sensing element A4221 and the sub-sensing element A4121. In further embodiments, the electrical signals output by the stationary conductive component A41, for example, the stationary sub-sensing element A4121, can reflect differences in characteristics such as positive and negative polarity, signal strength, signal arrangement rules, state duration, signal intensity, and / or state change rules, since the cable movement differs when the coil disk A20 and the installation housing A10, for example, the second housing A12, rotate relative to each other.Furthermore, cable movement can be assessed based on the electrical signal. Referring to Figures 25 and 27, the moving conductive component A42 is provided with several electrically connected moving sub-sensing elements A4221. The stationary sub-sensing element A4121 can comprise a first stationary sub-sensing element A4122 and a second stationary sub-sensing element A4123. The first stationary sub-sensing element A4122 carries a level signal. When the coil disk A20 and the installation housing A10, for example the second housing A12, rotate relative to each other, the first stationary sub-sensing element A4122 and the second stationary sub-sensing element A4123 are electrically connected or disconnected by the several moving sub-sensing elements A4221. The electrical signal can include the level signal output by the second stationary sub-sensing element A4123.In some embodiments, the level signal can also reflect the positive and negative polarity. In some embodiments, the first stationary sub-sensing element A4122 can input a high-level signal, causing the second stationary sub-sensing element A4123 to output the electrical signal, for example, a high-level signal, when the first stationary sub-sensing element A4122 and the second stationary sub-sensing element A4123 are electrically connected by the multiple moving sub-sensing elements A4221. When the first stationary sub-sensing element A4122 and the second stationary sub-sensing element A4123 are electrically separated by the multiple moving sub-sensing elements A4221, the second stationary sub-sensing element A4123 outputs the electrical signal, for example, a low-level signal. In some embodiments, the electrical signal, for example the high-level signal, can be generated by connecting the first stationary lower-level sensing element A4122 to a power supply end. In some embodiments, the electrical signal, for example the low-level signal, can be generated by grounding the first stationary lower-level sensing element A4122. In some embodiments, the multiple electrically connected, moving sub-sensing elements A4221 are distributed around the axis of rotation, which also allows for the adaptation of features such as the duration of the state and the rule set for the state change. For example, the multiple electrically connected, moving sub-sensing elements A4221 are distributed around the axis of rotation on the same circle. The distance between any two adjacent moving sub-sensing elements A4221 can vary to form an arrangement rule set that can reflect the cable movement. In some embodiments, the multiple movable lower detection elements A4221 are electrically connected by the movable conductive component A42. In some embodiments, the multiple movable lower detection elements A4221 are electrically connected by the stationary conductive component A41. In some embodiments, the electrical connection between the multiple lower detection elements A4221 is realized through the interaction of the stationary conductive component A41 and the movable conductive component A42. In some embodiments, the first fixed sub-sensing element A4122 and the second fixed sub-sensing element A4123 are distributed around the axis of rotation, which also allows for the adaptation of features such as the duration of the state and the rule set for the state change. For example, the first fixed sub-sensing element A4122 and the second fixed sub-sensing element A4123 are distributed around the axis of rotation on the same circle. The arrangement of the two moving sub-sensing elements A4122 can form an arrangement rule set that can reflect the cable movement. In some embodiments, the multiple movable sub-sensing elements A4221 can comprise a first movable sub-sensing element A4222 and a second movable sub-sensing element A4223. The distance between the first movable sub-sensing element A4222 and the axis of rotation and the distance between the second movable sub-sensing element A4223 and the axis of rotation are equal; that is, the first movable sub-sensing element A4222 and the second movable sub-sensing element A4223 are distributed around the axis of rotation on the same circle. In some embodiments, the first stationary lower detection element A4122 and the second stationary lower detection element A4123 are electrically connected or electrically separated by the first moving lower detection element A4222 and the second moving lower detection element A4223 when the coil disk A20 and the installation housing A10, for example the second housing A12, rotate relative to each other. Referring to Fig. 28, the distance between the second movable sub-sensing element A4223 and the axis of rotation is greater than the distance between the first movable sub-sensing element A4222 and the axis of rotation; that is, the multiple movable sub-sensing elements A4221 can be partially distributed around the axis of rotation on the same circle. Simultaneously, the distance between the second stationary sub-sensing element A4123 and the axis of rotation is greater than the distance between the first stationary sub-sensing element A4122 and the axis of rotation; that is, the multiple stationary sub-sensing elements A4121 can be partially distributed around the axis of rotation on the same circle. Thus, the first stationary sub-sensing element A4122, the second stationary sub-sensing element A4123, the first movable sub-sensing element A4222, and the second movable sub-sensing element A4223 interact. In some embodiments, the stationary lower detection element A4121 can be a rail, and the movable lower detection element A4221 can be a contact, with the electrical connection being established by contact between the contact and the rail. In some embodiments, the stationary lower detection element A4121 can be configured to correspond to the conductive rail A411, and the movable lower detection element A4221 can be configured to correspond to the conductive contact A421. Furthermore, the interaction of the stationary lower detection element A4121 with the movable lower detection element A4221 can be configured to correspond to the interaction of the conductive rail A411 with the conductive contact A421.In some embodiments, the stationary lower detection element A4121 can be a contact, the movable lower detection element A4221 can be a rail, the electrical connection being realized by the contact between the contact and the rail. It is understood that the interaction between the stationary lower detection element A4121 and the moving lower detection element A4221 is not limited to the type described here; the electrical connection can also be realized by other methods, for example, interactions of a projection with a projection, of balls, of a projection with a sliding groove, etc., which will not be explained further. Referring to Fig. 29, the stationary detection element A412 can comprise a sensor A4124, and the moving trigger element A422 can comprise several triggers A4224. When the coil disk A20 and the installation housing A10, for example, the second housing A12, rotate relative to each other, the sensor A4124 and each trigger A4224 move closer to or further away from each other. The sensor A4124 generates the electrical signal to be output by the stationary conductive element A41.By arranging the multiple triggers A4224, the electrical signal can reflect a detection state, in which the sensor A4124 detects the trigger A4224, and a non-detection state, in which the sensor does not detect the trigger A4224. It can also reflect the transition from the detection state to the non-detection state or vice versa, and it can even reflect features such as the duration of the state, the signal strength, and / or the rule set governing the state change. Furthermore, cable movement can be determined based on the electrical signal reflecting these features. In some embodiments, the sensor A4124 can be the induction element 135 in the embodiments described above. In some embodiments, the trigger A4224 can be the trigger element 142 in the embodiments described above. In some embodiments, the multiple triggers A4224 are distributed circumferentially around the axis of rotation, with the distance between some triggers A4224 being different. The sensor A4124 generates the electrical signal based on the distance, which can reflect the difference in distance, thereby enabling the detection of cable movement. In some embodiments, the triggers A4224 correspond to different detection parameters of the sensor A4124. The sensor A4124 serves to generate the electrical signal reflecting the distance and / or the detection parameters. In some embodiments, the release mechanism A4224 can include a first sub-release mechanism A4225 and a second sub-release mechanism A4226. In some embodiments, the first sub-release mechanism A4225 and the second sub-release mechanism A4226 are distributed around the axis of rotation, which also allows for the adaptation of features such as the duration of the state and the rule set for the state change. For example, the first sub-release mechanism A4225 and the second sub-release mechanism A4226 are distributed around the axis of rotation on the same circle. The arrangement of the two releases A4224 can form an arrangement rule set that can reflect cable movement. In some embodiments, the distance between the second sub-release A4226 and the axis of rotation is greater than the distance between the first sub-release A4225 and the axis of rotation; that is, the multiple releases A4224 can be partially distributed around the axis of rotation on the same circle. Simultaneously, the multiple sensors A4124 can also be partially distributed around the axis of rotation on the same circle. In some embodiments, multiple A4124 sensors may also be provided. In some embodiments, with regard to the arrangement and / or distribution of the trigger A4224 on the moving conductive component A42, reference can also be made to the arrangement and / or distribution of the moving sub-detection elements A4221, which is not explained further. In some embodiments, the arrangement and / or distribution of the sensors A4124 on the stationary conductive component A41 may also refer to the arrangement and / or distribution of the stationary sub-detection elements A4121, which is not explained further. In some embodiments, the electronic device A100, for example the main body A101, can process the electrical signal, identify the cable movement and then generate a movement command corresponding to the cable movement in order to control the electronic device A100, for example the data cable module A102. In some embodiments, the sensor A4124 can be a proximity sensor to generate the electrical signal when the trigger A4224 is approached. In some embodiments, the proximity sensor can be a Hall sensor, and the trigger A4224 can be a magnetic element. In some embodiments, the magnetic strength (i.e., the detection characteristic) and the distribution of the magnetic element can reflect cable movement. In some embodiments, the magnetic element can be the magnet in the embodiments described above. It is understandable that the arrangement and type as well as the arrangement method of the sensor A4124 and the trigger A4224 can be selected based on the requirements of the person skilled in the art, which is not explained further. Referring to Fig. 30, the stationary sensing component A412 can comprise multiple sensors A4124, and the moving trigger component A422 can comprise a trigger A4224. As the coil disk A20 and the installation housing A10, for example the second housing A12, rotate relative to each other, each sensor A4124 and the trigger A4224 move closer to or further away from each other. The sensor A4124 generates the electrical signal to be output by the stationary conductive component A41. In some embodiments, the sensor A4124 can comprise a first sensor A4125 and a second sensor A4126. In some embodiments, the first sensor A4125 and the second sensor A4126 are distributed around the axis of rotation, which also allows for the adaptation of features such as the duration of the state and the rule set for the state change. For example, the first sensor A4125 and the second sensor A4126 are distributed around the axis of rotation on the same circle. The arrangement of the two sensors A4124 can form an arrangement rule set that can reflect cable movement. In some embodiments, the distance between the second sensor A4126 and the axis of rotation is greater than the distance between the first sensor A4125 and the axis of rotation; that is, the multiple sensors A4124 can be partially distributed around the axis of rotation on the same circle. Simultaneously, the multiple triggers A4224 can also be partially distributed around the axis of rotation on the same circle. It is understandable that the arrangement position of sensor A4124 can be exchanged with the arrangement position of trigger A4224. In some embodiments, the sensor A4124 can be configured using the induction element 135 in the embodiments described above.

In some embodiments, the trigger A4224 can be configured using the trigger element 142 in the embodiments described above. In some embodiments, the trigger A4224 can be the trigger element 142 in the embodiments described above. In some embodiments, a device electrically connected to the stationary conductive component A41 can process the electrical signal, identify the cable movement, and then generate a motion command corresponding to the cable movement in order to control the electronic device A100, for example, the data cable module A102. Referring to Fig. 25, two of the first stationary sub-sensing elements A4122 and two of the second stationary sub-sensing elements A4123 can be present, wherein the two first stationary sub-sensing elements A4122 and the two second stationary sub-sensing elements A4123 can be arranged crosswise to each other in the circumferential direction of the axis of rotation. Of course, in other embodiments, the two first stationary sub-sensing elements A4122 and the two second stationary sub-sensing elements A4123 can be arranged one after the other in the circumferential direction of the axis of rotation. Referring to Fig. 26, two first fixed lower detection elements A4122 and one second fixed lower detection element A4123 are provided. In other embodiments, two second fixed lower detection elements A4123 can be connected to form a single element. Of course, in other embodiments, one first fixed lower detection element A4122 and two second fixed lower detection elements A4123 are provided. In other embodiments, two first fixed lower detection elements A4122 can be connected to form a single element. Referring to Fig. 25, at least one moving trigger component A422 has a level signal. When the coil disk A20 and the installation housing A10 rotate relative to each other, several stationary detection components A412 can be successively electrically connected or disconnected from the moving trigger component A422, so that the data cable module A102 or the main body A101 receives the level signal of the cable movement. The following describes a control method based on cable movement. This method can be applied to the data cable module A102 in the above embodiments, it can also be applied to the electronic device A100 in the above embodiments, and of course, it can also be applied to other electronic devices with a cable reel. In some embodiments, the electronic device A100, for example the main body A102, can be controlled in the method based on the cable movement. With reference to Fig. 31, Fig. 31 is a schematic diagram of the sequence of the method in some embodiments of the present application. The method may include the following: Step S1101: Receiving an electrical signal by a sensing module in a cable reel.
