Description

Technical Field

[0001] This application relates to the field of data cable technology, specifically to a retractable cable module and electronic device. Background Technology

[0002] In existing technologies, many electronic devices come with built-in data cables, which are coiled up and then released during use. However, electronic devices cannot achieve intelligent control based on the coiling or uncoiling of the data cable. Summary of the Invention

[0003] This application provides a retractable cable module, comprising: a housing; a spindle disposed within the housing and having a fixed conductive member thereon, the fixed conductive member being used for electrical connection to an external wiring or circuit board; a bushing rotatably connected to the side circumference of the spindle; a follower conductive member disposed on the bushing, the fixed conductive member elastically abutting against the follower conductive member on the side circumference of the spindle, the follower conductive member including a grounding element; and a data cable wound around the bushing, the data cable being electrically connected to the follower conductive member; wherein, the spindle and the bushing are inserted into each other, such that the follower conductive member and the fixed conductive member are electrically connected; the bushing is provided with a trigger element, the trigger element being a conductive element and connected to the grounding element; the fixed conductive member includes a first detection element, the first detection element being used for electrical connection to a high-level signal source through a first resistor; the trigger element and the first detection element cooperate to detect the movement of the data cable.

[0004] This application provides an electronic device, including the telescopic cable module described above.

[0005] The beneficial effects of this application are as follows: This application utilizes a winding reel formed by the cooperation of a mandrel and a bushing to wind data cables, thereby achieving data cable storage and carrying, and thus improving the user experience. The bushing can rotate relative to the mandrel, allowing the data cable to be wound by rotating the winding reel.

[0006] Furthermore, the follower conductive component can rotate together with the bushing while maintaining electrical connection with the fixed conductive component. Consequently, the data cable can be externally connected to the fixed conductive component via the follower conductive component, specifically to external wiring or a circuit board. Simultaneously, the trigger on the bushing can detect data cable movement, such as data cable stretching or retraction, and the detection results can be applied to intelligent control to improve the user experience.

Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0010] The reference to "embodiment" in this application means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0011] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0012] This application describes an electronic device. The electronic device may include a data cable for connecting to an external device and providing power to the external device, specifically for charging. Alternatively, the electronic device may also transmit data to the external device via the data cable. In some embodiments, the external device may also provide power to the electronic device via the data cable, specifically for charging.

[0013] Electronic devices can be computers, mobile phones, power banks, docking stations, desktop charging stations, sockets, retractable cable modules, or power adapters, etc. The specific selection and design of electronic devices can be based on the needs of those skilled in the art, as long as they have data cables.

[0014] The following section will use the telescopic cable module as an example. The content described should not be limited to the telescopic cable module. Other electronic devices besides the telescopic cable module can also use the various structures described here and achieve the corresponding functions.

[0015] The retractable cable module can be used to wind up the data cable, enabling the data cable to be retracted. In some embodiments, the data cable may be part of the retractable cable module.

[0016] In some embodiments, the retractable cable module can be used alone or installed in electronic devices such as computers, mobile phones, power banks, docking stations, desktop charging stations, sockets, or power adapters. The specific electronic devices can be selected according to the needs of those skilled in the art, and the retractable cable module can be set in the electronic devices, which will not be elaborated further.

[0017] The retractable cable module can be electrically connected to two electronic devices to enable data transmission or communication between them, or to allow one electronic device to charge another. Alternatively, the retractable cable module can be installed in at least one of the two electronic devices.

[0018] In some scenarios, the housing of the telescopic cable module can serve as the housing of other devices, such as electronic devices, since the telescopic cable module is installed in other devices, such as electronic devices. That is, the telescopic cable module and other devices, such as electronic devices, can share the housing structure.

[0019] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 This is an exploded view of the telescopic line module in some embodiments of this application. Figure 2 for Figure 1 The diagram shows a structural schematic of the telescopic line module in some embodiments. Figure 3 for Figure 1 The illustrated embodiment shows a partial structural diagram of the telescopic cable module in some embodiments. The telescopic cable module 100 may include a housing 10, a winding reel 20 rotatably connected to the housing 10, a data cable 30 wound on the winding reel 20, and a drive member 40 installed between the housing 10 and the winding reel 20. The housing 10 can support structures such as the winding reel 20, the data cable 30, and the drive member 40 within the telescopic cable module 100. The winding reel 20 can rotate relative to the housing 10 to wind or unwind the data cable 30. The data cable 30 may be partially housed within the housing 10 and wound on the winding reel 20.

[0020] The drive unit 40 can drive the winding reel 20 to rotate, thereby winding or unwinding the data cable 30. In some embodiments, the data cable 30 may be omitted. In some embodiments, the drive unit 40 may be omitted.

[0021] In some scenarios, the winding reel 20 can wind the data cable 30 when rotating, causing the data cable 30 to retract into the housing 10. In other scenarios, when the user pulls the data cable 30 out of the housing 10, the winding reel 20 can move and rotate under the pull of the data cable 30, releasing the data cable 30 and causing the data cable 30 to extend out of the housing 10.

[0022] Please see Figure 1 and Figure 2 The housing 10 may be a shell structure, a frame structure, or a plate structure, or other structures that can form the installation space 1001. In some embodiments, the housing 10 may have an installation space 1001 to accommodate structures within the telescopic cable module 100, such as the winding reel 20, the data cable 30, the drive unit 40, etc.

[0023] The housing 10 can be made of a rigid material, but other types of materials can also be used to achieve the function of the housing 10. In fact, the housing 10 can be made of a variety of materials.

[0024] The housing 10 may include a first housing 11 and a second housing 12 connected together. The first housing 11 and the second housing 12 may be connected by welding, bonding, snap-fitting, screwing, plugging or other means known to those skilled in the art, which will not be elaborated here.

[0025] In some embodiments, the first housing 11 and the second housing 12 may cooperate to define an installation space 1001. In some embodiments, the installation space 1001 may be disposed on the first housing 11. Furthermore, in a further embodiment, the second housing 12 may be omitted. In some embodiments, the installation space 1001 may be disposed on the second housing 12. Furthermore, in a further embodiment, the first housing 11 may be omitted.

[0026] Please see Figure 4 , Figure 4 for Figure 2 The schematic diagram of the telescopic cable module 100 in the illustrated embodiment is shown in some other embodiments. The housing 10 may include a first housing 11 and a circuit board 13. The first housing 11 is connected to one side of the circuit board 13 to define the installation space 1001. That is, in the housing 10 defining the installation space 1001, either the first housing 11 or the second housing 12 may be replaced by the circuit board 13.

[0027] Understandably, the circuit board 13 may not be part of the housing 10 and may be installed in other locations of the telescopic cable module 100, or even in an electronic device. Additionally, when the first housing 11 and the second housing 12 are engaged, the circuit board 13 may also be installed on either the first housing 11 or the second housing 12.

[0028] Please see Figure 1 and Figure 5 , Figure 5 for Figure 1The illustrated embodiment shows a partial structural diagram of the retractable cable module 100 in some embodiments. The data cable 30 can be used to electrically connect to an electronic device, transmit data with the electronic device, and charge the electronic device. In some embodiments, the retractable cable module 100, such as the data cable 30, can also be electrically connected to other data cables (also referred to as external cables). In some embodiments, the data cable 30 can be released from the winding reel 20 or wound around the winding reel 20, thereby achieving length adjustment of the data cable 30 outside the housing 10. In some embodiments, the data cable 30 can extend from outside the housing 10, such as the mounting space 1001, into the housing 10, such as the mounting space 1001, and can be wound around the winding reel 20. The data cable 30 can also be partially released outside the housing 10, such as the mounting space 1001, by rotating the winding reel 20, or partially wound around the housing 10, such as the mounting space 1001, by rotating the winding reel 20.

[0029] The data cable 30 may be a USB Type-C data cable, a Lightning data cable, a Micro USB data cable, or other types of data cables known to those skilled in the art, which will not be described in detail.

[0030] One end of the data cable 30 is located outside the housing 10, for example, the mounting space 1001, for electrical connection to an electronic device, while the other end may be located inside the housing 10, for example, the mounting space 1001. Of course, in a further embodiment, the other end of the data cable 30 may also be located outside the housing 10, for example, the mounting space 1001, for electrical connection to another electronic device.

[0031] In some scenarios, one end of the data cable 30 can be fixed to the winding reel 20 and electrically connected to an electronic device through the winding reel 20, while the other end can be located outside the housing 10, for example, the mounting space 1001. In some embodiments, the middle part of the data cable 30 between its two ends can be fixed to the winding reel 20, and both ends can be located outside the housing 10, for example, the mounting space 1001.

[0032] In some scenarios, one end of the data cable 30 is located outside the housing 10, such as the mounting space 1001, for electrical connection to an electronic device, and the other end may also be located outside the housing 10, such as the mounting space 1001, for electrical connection to another electronic device, while the middle portion of the data cable 30 can be fixedly wound on the winding reel 20. Of course, in other embodiments, the other end of the data cable 30 can be fixed inside the housing 10, such as the mounting space 1001, on the winding reel 20, and can even be electrically connected to other electronic devices through the winding reel 20.

[0033] The data cable 30 can extend from outside the housing 10, for example, into the installation space 1001, and be wound around the winding reel 20. Part of the data cable 30 can be released to the outside of the housing 10, for example, the installation space 1001 by rotating the winding reel 20, or part of the data cable 30 can be wound into the housing 10, for example, the installation space 1001 by rotating the winding reel 20.

[0034] The data cable 30 may include a positive power supply wire, a negative power supply wire, and a signal transmission line. The positive and negative power supply wires work together to form a complete power supply loop, ensuring that the current can form a closed loop and realize power transmission. The signal transmission line is used for data transmission.

[0035] Please see Figure 1 and Figure 3 The driving element 40 can be a motor, or it can be an elastic element that provides power based on elastic deformation, or it can be any other power source that can drive the winding reel 20 to rotate. In some embodiments, the elastic element can be a spring, torsion spring, or coil spring, etc.

[0036] The drive element 40 can be installed inside the housing 10, for example, the mounting space 1001, or it can be located outside the housing 10, for example, the mounting space 1001. In some embodiments, the drive element 40 can be located on one side of the winding reel 20 along the rotation axis of the winding reel 20.

[0037] The driving element 40, such as an elastic element, can undergo elastic deformation, thereby driving the winding disk 20 to rotate based on the elastic deformation.

[0038] In some embodiments, the drive element 40, such as an elastic element, may connect the housing 10, such as the first housing 11, and the winding reel 20.

[0039] In some embodiments, the drive member 40, such as an elastic member, can drive the winding disc 20 to rotate based on elastic deformation, and the winding disc 20 further winds the data line 30, so that the data line 30 retracts into the housing 10, such as the mounting space 1001.

[0040] In some scenarios, when a user pulls the data cable 30 outside the housing 10, such as the installation space 1001, the winding reel 20 can move under the pull of the data cable 30, and thus rotate to release the data cable 30. In some scenarios, when the winding reel 20 rotates to release the data cable 30, it will cause the driving component 40, such as an elastic component, to undergo elastic deformation. Then, when the user removes the force pulling the data cable 30, the driving component 40, such as the elastic component, can drive the winding reel 20 to rotate based on the elastic deformation, and the winding reel 20 will further wind the data cable 30.

[0041] Please see Figure 1 , Figure 6 and Figure 7 , Figure 6 for Figure 1The illustrated embodiment shows an assembly diagram of a portion of the structure of the winding reel 20 in some embodiments. Figure 7 for Figure 1 The illustrated embodiment shows an assembly diagram of a portion of the winding reel 20 in some embodiments. The winding reel 20 may include a spindle 21, a bushing 22 rotatably connected to the side periphery of the spindle 21, a follower conductive member 23 disposed on the bushing 22, and a baffle 24 disposed on the bushing 22. The bushing 22 is rotatable relative to the spindle 21 to wind the data cable 30. The follower conductive member 23 rotates with the bushing 22 and simultaneously abuts against the spindle 21 to achieve electrical connection. The baffle 24 may be disposed on the bushing 22 to block the data cable 30, ensuring that the data cable 30 can be wound orderly on the bushing 22.

[0042] The mandrel 21 can be mounted on the housing 10, specifically through methods such as plug-in connection, welding, bonding, threaded connection, or snap-fit ​​connection. Of course, it can also be connected using other connection methods well known to those skilled in the art. In some embodiments, the mandrel 21 can be mounted on the first housing 11. In some embodiments, the mandrel 21 can be mounted on the second housing 12. In some embodiments, the mandrel 21 can be mounted on the circuit board 13.

[0043] In some embodiments, the spindle 21 can extend from inside the housing 10, for example, the mounting space 1001, to outside the housing 10, for example, the mounting space 1001. For example, the spindle 21 can pass through the first housing 11 to extend from inside the housing 10, for example, the mounting space 1001, to outside the housing 10, for example, the mounting space 1001. For example, the spindle 21 can pass through the second housing 12 to extend from inside the housing 10, for example, the mounting space 1001, to outside the housing 10, for example, the mounting space 1001. For example, the spindle 21 can pass through the circuit board 13 to extend from inside the housing 10, for example, the mounting space 1001, to outside the housing 10, for example, the mounting space 1001. In a further embodiment, the spindle 21 can extend from inside the housing 10, for example, the mounting space 1001, to outside the housing 10, for example, thereby enabling electrical connection to external devices or other structures. For example, the spindle 21 can be electrically connected to the circuit board 13. For example, the spindle 21 can be electrically connected to electronic components or circuit boards within an electronic device. For example, the spindle 21 can be electrically connected to external wiring.

[0044] In some embodiments, the mandrel 21 can be inserted into the bushing 22, for example, the mandrel 21 can be inserted into the bushing 22 along the axial direction of the mandrel 21 and rotatedly connected to the bushing 22.

[0045] Please see Figure 6 , Figure 7 and Figure 8 , Figure 8 for Figure 7The exploded view of the mandrel 21 in some embodiments is shown in the illustration. The mandrel 21 may include a mounting shaft 25, an insulating member 26 disposed on the mounting shaft 25, and a fixed conductive member 27 disposed on the insulating member 26. The mounting shaft 25 enables the mounting of structures on the mandrel 21, such as the insulating member 26 and the fixed conductive member 27. The fixed conductive member 27 is conductive. The insulating member 26 supports the fixed conductive member 27 and provides insulation between the fixed conductive member 27 and the mounting shaft 25, as well as insulation between the fixed conductive members 27 themselves.

[0046] The spindle 21, for example, the mounting shaft 25, can define the axis of rotation of the winding disc 20.

[0047] The mounting shaft 25 serves as the primary structure connecting the spindle 21 to the housing 10. In some embodiments, the mounting shaft 25 may be made of a conductive material, thereby enabling it to conduct electricity. That is, the mounting shaft 25 may be referred to as a conductor, or a fifth conductor. Of course, the mounting shaft 25 may also be made of a material other than conductive.

[0048] The mounting shaft 25 may include a first shaft portion 251 and a second shaft portion 252 connected along the extending direction (e.g., axially) of the mandrel 21. In some embodiments, the first shaft portion 251 and the second shaft portion 252 are coaxially arranged, but they may also be non-coaxial. In some embodiments, the outer diameter of the first shaft portion 251 is smaller than the outer diameter of the second shaft portion 252. That is, the cross-sectional area of ​​the first shaft portion 251 perpendicular to the rotation axis of the winding disc 20 may be smaller than the cross-sectional area of ​​the second shaft portion 252 perpendicular to the rotation axis of the winding disc 20. Of course, the outer diameter of the first shaft portion 251 may also be equal to the outer diameter of the second shaft portion 252. It is understood that the outer diameter refers to the radius of the largest circumscribed circle of the outer contour of the cross-section of the mounting shaft 25 perpendicular to the rotation axis of the winding disc 20. The largest circumscribed circle is the circle circumscribed by the maximum number of apex corners of the outer contour of the cross-section.

[0049] In some embodiments, at least one of the first shaft portion 251 and the second shaft portion 252 may define the axis of rotation of the winding reel 20.

[0050] The first shaft portion 251 and the second shaft portion 252 can be connected by means of plug-in mating, welding, bonding, threaded connection, or snap-fit ​​connection. Of course, they can also be connected by other connection methods known to those skilled in the art. In some embodiments, at least one of the first shaft portion 251 and the second shaft portion 252 is conductive. That is, in some embodiments, the first shaft portion 251 and / or the second shaft portion 252 can be referred to as a conductor, i.e., a fifth conductor.

[0051] Please see Figure 3 The mounting shaft 25, for example, the second shaft portion 252, can be connected to the drive element 40, for example, the elastic element.

[0052] Please see Figure 2 The mounting shaft 25, for example, the second shaft portion 252, can extend from inside the housing 10, for example, the mounting space 1001, to outside the housing 10, for example, the mounting space 1001. Of course, the first shaft portion 251 can also extend from inside the housing 10, for example, the mounting space 1001, to outside the housing 10, for example, the mounting space 1001.

[0053] Please see Figure 4 The mounting shaft 25, for example, the first shaft portion 251, can be electrically connected to the circuit board 13. In other embodiments, the mounting shaft 25, for example, the first shaft portion 251, can be electrically connected to an external wiring connection.

[0054] Of course, in some embodiments, the second shaft portion 252 may be electrically connected to the circuit board 13. In other embodiments, the second shaft portion 252 may be electrically connected to an external wiring connection.

[0055] Please see Figure 6 , Figure 7 and Figure 8 The insulating element 26 can be disposed on the mounting shaft 25, such as the first shaft portion 251, to achieve insulation between two conductive structures. For example, the insulating element 26 can insulate the mounting shaft 25, such as the first shaft portion 251, from the fixed conductive member 27. For example, the insulating element 26 can insulate any two conductive structures in the fixed conductive member 27.

[0056] In some embodiments, when the mounting shaft 25, for example, the first shaft portion 251, does not have a conductive function and can achieve insulation, the insulating member 26 can be omitted. The function of the insulating member 26 can be achieved by the mounting shaft 25, for example, the first shaft portion 251, and the installation of the fixed conductive member 27 can be performed. In a further embodiment, any two conductive structures in the fixed conductive member 27 can be insulated and isolated by the mounting shaft 25, for example, the first shaft portion 251.

[0057] The insulating component 26 may include a first insulating base 261 and a second insulating base 262 that are detachably connected to each other. The first insulating base 261 and the second insulating base 262 can cooperate to fix the installation of the conductive component 27.

[0058] The first insulating seat 261 and the second insulating seat 262 can be sleeved on the side circumferential surface of the mounting shaft 25, such as the first shaft portion 251. Furthermore, in a further embodiment, since the outer diameter of the first shaft portion 251 is smaller than the outer diameter of the second shaft portion 252, the insulating member 26, such as the first insulating seat 261 and the second insulating seat 262, can be closer to the rotation axis of the winding reel 20, making the structure more compact and the volume smaller.

[0059] In some embodiments, the first insulating seat 261 and the second insulating seat 262 may be arranged along the rotation axis of the winding reel 20 and may be connected to each other. In a further embodiment, the first insulating seat 261 and the second insulating seat 262 may clamp and fix the conductive member 27.

[0060] In some embodiments, on a projection plane perpendicular to the mounting shaft 25, such as the axial direction of the second shaft portion 252, the outer contour projection of the insulating member 26 is located within or coincides with the outer contour projection of the second shaft portion 252, thereby ensuring the appearance consistency of the mounting shaft 25 and making the structure more compact and smaller in size.

[0061] In some embodiments, one of the first insulating seat 261 and the second insulating seat 262 may be omitted, or the first insulating seat 261 and the second insulating seat 262 may be connected as a single structure.

[0062] The fixed conductive member 27 can be provided on the insulating member 26 to be insulated from the mounting shaft 25, such as the first shaft portion 251. Of course, when the insulating member 26 is omitted, the fixed conductive member 27 can be directly provided on the mounting shaft 25, such as the first shaft portion 251, or provided on the mounting shaft 25, such as the first shaft portion 251, through other structures, and can further achieve insulation.

[0063] In some embodiments, the fixed conductive member 27 may be insulated from the first shaft portion 251. In some embodiments, the fixed conductive member 27 may be insulated from the second shaft portion 252.

[0064] The telescopic cable module 100, for example, with a fixed conductive member 27, can be electrically connected to an electronic device to enable data transmission, communication, or power supply. In some embodiments, the fixed conductive member 27 can be electrically connected to a circuit board 13. In some embodiments, the fixed conductive member 27 can also be electrically connected to an external wire, and further, it can be electrically connected to an electronic device or circuit board via an external wire.

[0065] The fixed conductive component 27 may include multiple conductors disposed on the insulating component 26, such as a first conductor 271, a second conductor 272, a third conductor 273, a fourth conductor 274, etc. Of course, it may also include a fifth conductor, etc. The specific number of conductors can be set based on the needs of those skilled in the art, and will not be elaborated here.

[0066] Multiple conductors in the fixed conductive component 27 can be insulated from each other by the insulating component 26, or they can be insulated from each other by other structures, or even by being spaced apart to achieve insulated connection. That is, any two conductors among the first conductor 271, the second conductor 272, the third conductor 273, the fourth conductor 274, etc., can be insulated from each other.

[0067] Conductors, such as first conductor 271, second conductor 272, third conductor 273, and fourth conductor 274, may include a ring portion 2711 and a first electrical connection portion 2712 connected to the ring portion 2711. The ring portion 2711 and the first electrical connection portion 2712 are electrically connected to conduct electricity.

[0068] In some embodiments, conductors such as the first conductor 271, the second conductor 272, the third conductor 273, and the fourth conductor 274 can extend from inside the housing 10, for example, the mounting space 1001, to outside the housing 10, for example, through the first electrical connection portion 2712. In a further embodiment, the first electrical connection portion 2712 can be electrically connected to external devices or other structures. For example, the first electrical connection portion 2712 can be electrically connected to the circuit board 13. For example, the first electrical connection portion 2712 can be electrically connected to electronic components or circuit boards within an electronic device. For example, the first electrical connection portion 2712 can be electrically connected to external wiring.

[0069] The annular portion 2711 can be mounted on the insulating member 26 to have a contact surface on the side circumferential surface of the mandrel 21. Specifically, the outer circumferential surface of the annular portion 2711 is the contact surface. In some embodiments, the annular portion 2711 can be sleeved on the mounting shaft 25, such as the first shaft portion 251, to be directly connected to the mounting shaft 25, such as the first shaft portion 251, or it can be connected to the mounting shaft 25, such as the first shaft portion 251, through the insulating member 26, or even through other structures.

[0070] In some embodiments, since the outer diameter of the first shaft portion 251 is smaller than the outer diameter of the second shaft portion 252, the circumferential portion 2711 can be closer to the rotation axis of the winding disc 20, resulting in a more compact structure and smaller volume.

[0071] In some embodiments, the annular portions 2711 among the plurality of conductors may be arranged along the rotation axis of the winding reel 20 and may be mutually insulated from each other. In a further embodiment, the first insulating seat 261 and the second insulating seat 262 may clamp and fix the annular portions 2711.

[0072] In some embodiments, on a projection plane perpendicular to the axial direction of the second shaft portion 252, the outer contour projection of the circumferential portion 2711 is located within or coincides with the outer contour projection of the second shaft portion 252, thereby ensuring the appearance consistency of the spindle 21 and making the structure more compact and smaller in size.

[0073] In some embodiments, a plurality of conductors, such as a first conductor 271, a second conductor 272, a third conductor 273, a fourth conductor 274, etc., may be arranged along the axial direction of the mounting shaft 25, such as the first shaft portion 251.

[0074] In some embodiments, the first electrical connection portion 2712 of a plurality of conductors, such as the first conductor 271, the second conductor 272, the third conductor 273, the fourth conductor 274, etc., may be provided at one end or on the side circumferential surface of the spindle 21 in the axial direction.

[0075] In some embodiments, the first electrical connection portion 2712 of a plurality of conductors, such as the first conductor 271, the second conductor 272, the third conductor 273, the fourth conductor 274, etc., may be provided on the housing 10.

[0076] In some embodiments, the mounting shaft 25, such as the first shaft portion 251 and the second shaft portion 252, may include a first electrical connection portion 2712 because it is conductive and can be externally connected.

[0077] In some embodiments, the first electrical connection portion 2712 is arranged on the side of the first shaft portion 251 opposite to the second shaft portion 252, thereby ensuring the appearance consistency of the spindle 21 and making the structure more compact and smaller in size.

[0078] Please see Figure 6 , Figure 7 , Figure 8 and Figure 9 , Figure 9 for Figure 8 The illustrated embodiment shows an assembly diagram of the conductor in some embodiments. The fixed conductive member 27 may also include a conductor, such as a detection element 28, disposed on the insulating member 26. The detection element 28 enables the detection of data line operation. In some embodiments, the detection element 28 may not be part of the fixed conductive member 27.

For example, the first external connection 2812 can be electrically connected to electronic components or circuit boards within an electronic device. For example, the first external connection 2812 can be electrically connected to an external wiring.

[0082] The first contact portion 2811 can be mounted on the insulating member 26 to have a contact surface on the side circumferential surface of the mandrel 21. Specifically, the outer circumferential surface of the first contact portion 2811 is the contact surface.

[0083] In some embodiments, the first contact portion 2811 may be disposed on the side periphery of the mounting shaft 25, such as the first shaft portion 251, to be directly connected to the mounting shaft 25, such as the first shaft portion 251, or may be connected to the mounting shaft 25, such as the first shaft portion 251, through the insulating member 26, or even through other structures.

[0084] In some embodiments, since the outer diameter of the first shaft portion 251 is smaller than the outer diameter of the second shaft portion 252, the first contact portion 2811 can be closer to the rotation axis of the winding disc 20, making the structure more compact and smaller in size.

[0085] In some embodiments, in the fixed conductive member 27, the circumferential portion 2711 may be mutually insulated from the first contact portion 2811.

[0086] In some embodiments, on a projection plane perpendicular to the axial direction of the second shaft portion 252, the outer contour projection of the first contact portion 2811 is located within or coincides with the outer contour projection of the second shaft portion 252, thereby ensuring the appearance consistency of the spindle 21 and making the structure more compact and smaller in size.

[0087] Understandably, the arrangement of the second detection element 282 can be referenced to the arrangement of the first detection element 281, and will not be repeated here.

In some embodiments, the bushing 22 may have a fixing hole 2001 on its side circumferential surface to allow the data cable 30 to pass through, thereby fixing the data cable 30 to the bushing 22. In some embodiments, the fixing hole 2001 may be provided through the side circumferential surface of the bushing 22.

[0092] The bushing 22 may include a first enclosure portion 221 and a second enclosure portion 222 that cooperate with each other. The first enclosure portion 221 and the second enclosure portion 222 may surround the mounting shaft 25, such as the first shaft portion 251 and the second shaft portion 252. In some embodiments, the first enclosure portion 221 and the second enclosure portion 222 are in contact with each other. In some embodiments, the first enclosure portion 221 and the second enclosure portion 222 may be connected by means of insertion and mating, welding, bonding, threaded connection or snap connection, etc., and of course, other connection methods known to those skilled in the art may also be used. In some embodiments, the first enclosure portion 221 and the second enclosure portion 222 may be an integral structure.

In some embodiments, the follower conductive member 23 can elastically abut against the fixed conductive member 27 on the side circumferential surface of the mandrel 21 to conduct electricity. In a further embodiment, the follower conductive member 23 can elastically abut against a conductor such as a first conductor 271, a second conductor 272, a third conductor 273, a fourth conductor 274, a detection element 28, etc. In some embodiments, the follower conductive member 23 can elastically abut against a contact surface (e.g., the outer circumferential surface of the circumferential portion 2711, or the outer circumferential surface of the contact portion). In some embodiments, the follower conductive member 23 can elastically abut against the circumferential portion 2711. In some embodiments, the follower conductive member 23 can elastically abut against a contact portion such as the first contact portion 2811 or the second contact portion 2821.

[0094] In some embodiments, the follower conductive member 23 may be at least partially disposed on the bushing 22, for example, the first enclosure portion 221. In some embodiments, the follower conductive member 23 may be at least partially disposed on the bushing 22, for example, the second enclosure portion 222.

[0095] In some embodiments, the follower conductive member 23 may include multiple conductive elements 231, such as a first conductive element 2311, a second conductive element 2312, a third conductive element 2313, a fourth conductive element 2314, a fifth conductive element 2315, etc. The specific number of conductive elements 231 can be set based on the data line 30, or it can be set based on the number of conductors in the fixed conductive member 27.

Of course, the conductive element 231, such as the first conductive element 2311, can also elastically abut against the side peripheral surface of a conductive body provided according to a first conductor 271, a second conductor 272, a third conductor 273, or a fourth conductor 274 on the side peripheral surface of the spindle 21.

[0098] In some embodiments, the conductive element 231, such as the second conductive element 2312, can elastically abut against the first conductive body 271, such as the contact surface, on the side circumferential surface of the mandrel 21 to achieve conductivity.

[0099] In some embodiments, the conductive element 231, such as the third conductive element 2313, can elastically abut against the second conductive element 272, such as the contact surface, on the side circumferential surface of the mandrel 21 to achieve conductivity.

[0100] In some embodiments, the conductive element 231, such as the fourth conductive element 2314, can elastically abut against the third conductive element 273, such as the contact surface, on the side circumferential surface of the mandrel 21 to achieve conductivity.

[0101] In some embodiments, the conductive element 231, such as the fifth conductive element 2315, can elastically abut against the fourth conductive element 274, such as the contact surface, on the side circumferential surface of the mandrel 21 to achieve conductivity.

[0102] The conductive element 231 can elastically abut against the ring portion 2711, thereby achieving electrical connection.

For example, in some embodiments, the conductive element 231, such as the fifth conductive element 2315, can elastically abut against the contact surface of the fourth conductor 274, such as the ring portion 2711, on the side peripheral surface of the spindle 21 to achieve conductivity.

[0103] The follower conductive member 23 may have a second electrical connection portion 232 provided on the side peripheral surface of the spindle 21. In some embodiments, the follower conductive member 23, for example, the second electrical connection portion 232, may be electrically connected to the data line 30 to achieve conductivity. Of course, the position of the second electrical connection portion 232 is adjustable and is not limited to the embodiments listed herein.

[0104] In some embodiments, the conductive element 231, for example, the first conductive element 2311, may be provided with a first conductive portion 2321. In some embodiments, the conductive element 231, for example, the second conductive element 2312, may be provided with a second conductive portion 2322.

[0105] In some embodiments, the second electrical connection portion 232 may include the first conductive portion 2321 in the above embodiments. In some embodiments, the second electrical connection portion 232 may include the second conductive portion 2322 in the above embodiments.

In some embodiments, the second electrical connection portion 232 may include the fourth conductive portion 2324 in the above embodiments. In some embodiments, the second electrical connection portion 232 may include the fifth conductive portion 2325 in the above embodiments.

[0106] In some embodiments, the conductive element 231, such as the first conductive element 2311, can be electrically connected to the data line 30, such as the positive power line, via the first conductive portion 2321. Furthermore, in some embodiments, the data line 30, such as the positive power line, can be externally connected via the mounting shaft 25, such as the first shaft portion 251.

[0107] In some embodiments, the conductive element 231, such as the second conductive element 2312, can be electrically connected to the data line 30, such as the signal transmission line, via the second conductive portion 2322. Furthermore, in some embodiments, the data line 30, such as the signal transmission line, can be externally connected via the first conductive element 271, such as the first electrical connection portion 2712.

[0108] In some embodiments, the conductive element 231, such as the third conductive element 2313, can be electrically connected to the data line 30, such as the signal transmission line, via the third conductive portion 2323. Furthermore, in some embodiments, the data line 30, such as the signal transmission line, can be externally connected via the second conductive element 272, such as the first electrical connection portion 2712.

[0109] In some embodiments, the conductive element 231, such as the fourth conductive element 2314, can be electrically connected to the data line 30, such as the signal transmission line, via the fourth conductive portion 2324. Furthermore, in some embodiments, the data line 30, such as the signal transmission line, can be externally connected via the third conductive element 273, such as the first electrical connection portion 2712.

[0110] In some embodiments, the conductive element 231, such as the fifth conductive element 2315, can be electrically connected to the data line 30, such as the negative power line, via the fifth conductive portion 2325. Furthermore, in some embodiments, the conductive element 231, such as the fifth conductive element 2315, can also be referred to as a grounding element. Furthermore, in some embodiments, the data line 30, such as the negative power line, can be externally connected via the fourth conductor 274, such as the first electrical connection portion 2712.

[0111] Please see 6 and Figure 7 The follower conductive component 23 may include a conductive element 231, such as a trigger element 29. The trigger element 29 can cooperate with the detection element 28 to detect the movement of the data line.

[0112] In some embodiments, the setting method of the trigger 29 can be referred to the setting of the conductive element 231, such as the first conductive element 2311, the second conductive element 2312, the third conductive element 2313, the fourth conductive element 2314, the fifth conductive element 2315, etc., which will not be described in detail.

[0113] In some embodiments, the trigger 29 may also be connected to one of the conductive elements 231, such as the first conductive element 2311, the second conductive element 2312, the third conductive element 2313, the fourth conductive element 2314, the fifth conductive element 2315, etc.

[0114] In some embodiments, the trigger member 29 may elastically abut against the detection member 28, such as the first detection member 281 or the second detection member 282, to cooperate with the detection member 28, such as the first detection member 281 or the second detection member 282, to detect the operation of the data line. In some embodiments, the trigger member 29 may elastically abut against the contact portion, such as the first contact portion 2811 or the second contact portion 2821, to conduct electricity and detect the operation of the data line.

[0115] In some embodiments, the trigger 29 may be at least partially disposed on the bushing 22, for example, the first enclosure portion 221. In some embodiments, the trigger 29 may be at least partially disposed on the bushing 22, for example, the second enclosure portion 222. In some embodiments, the bushing 22, for example, the first enclosure portion 221, may be provided with a clamping portion 223 to clamp and fix the trigger 29.

[0116] In some embodiments, the trigger 29 may include a connecting segment 291, a transition segment 292, and an abutment segment 293 connected in sequence. The connecting segment 291 may be connected to one of the conductive elements 231, such as a first conductive element 2311, a second conductive element 2312, a third conductive element 2313, a fourth conductive element 2314, a fifth conductive element 2315, etc. The abutment segment 293 may be used to elastically abut against the detection element 28, such as a first detection element 281 or a second detection element 282, to detect the operation of the data line.

[0117] In some embodiments, the abutment segment 293 may be disposed opposite to the connecting segment 291, thereby enabling the transition segment 292 to provide an elastic force to the trigger 29, allowing the trigger 29 to elastically abut against contact portions such as the first contact portion 2811 and the second contact portion 2821. In some embodiments, the transition segment 292 may elastically deform, and provide an elastic force based on the elastic deformation. The distance between the abutment segment 293 and the connecting segment 291 provides space for the movement of the abutment segment 293.

[0118] Of course, in other embodiments, the abutment segment 293 may also be elastically deformable, and provide an elastic force based on the elastic deformation. Additionally, the connecting segment 291 may also be elastically deformable, and provide an elastic force based on the elastic deformation.

[0119] In some embodiments, the abutting section 293 has an arc-shaped abutting surface 2931 on the side opposite to the connecting section 291. The arc-shaped abutting surface 2931 can reduce the contact area with the detection element 28, such as the first detection element 281 or the second detection element 282, while also achieving good contact.

[0120] In some embodiments, the transition section 292 can be bent to connect one end to the connecting section 291 and the other end to the abutment section 293, thereby balancing the internal stress of the transition section 292 when the trigger 29 elastically deforms, effectively avoiding the breakage problem of the trigger 29 due to uneven internal stress distribution.

[0121] In some embodiments, the connecting segment 291 has an inner side surface 2911 facing the abutting segment 293, and also has a connecting surface 2912 connected to the inner side surface 2911 and perpendicular to each other, and the connecting segment 291 is connected to a fifth conductive element 2315, such as a grounding element, at the connecting surface 2912.

[0122] In some embodiments, the clamping part 223 may clamp the trigger member 29, such as the connecting segment 291, thereby allowing the abutting surface 2931 of the abutting segment 293 to be exposed in the clamping part 223 to contact the detection member 28, such as the first detection member 281 or the second detection member 282.

[0123] In some embodiments, the abutment surface 2931 of the trigger member 29, such as the abutment section 293, can elastically abut against the contact portion of the detection member 28, such as the first detection member 281 or the second detection member 282, on the side peripheral surface of the spindle 21, so as to achieve electrical connection and conduction.

[0124] Please see Figure 1 , Figure 3 and Figure 5 A baffle 24 may be disposed on the bushing 22. The baffle 24 may cooperate with the second housing 12 or the circuit board 13 to limit the data line 30 on the bushing 22, so as to make the structure more compact and minimize the axial size of the telescopic cable module 100 on the winding reel 20. In some embodiments, there may be multiple baffles 24, and two adjacent baffles 24 may limit the data line 30 on the bushing 22. Of course, in other embodiments, the baffle 24 may be omitted to make the structure more compact and minimize the axial size of the telescopic cable module 100 on the winding reel 20.

[0125] The baffle 24 can isolate the driver 40 from the data cable 30, effectively preventing the driver 40 from damaging the data cable 30.

[0126] Please see Figure 3 The baffle 24 can be used to connect the drive element 40, such as an elastic element. In some scenarios, the drive element 40, such as an elastic element, can connect the baffle 24 and the housing 10. In some scenarios, the drive element 40, such as an elastic element, can connect the baffle 24 and the mounting shaft 25, such as the second shaft portion 252. In some embodiments, the baffle 24 may be provided with a groove to accommodate the drive element 40, such as an elastic element, so as to make the structure more compact and minimize the axial dimension of the telescopic wire module 100 on the winding reel 20.

[0127] In some embodiments, the mandrel 21 can be inserted into the bushing 22 at the end where the baffle 24 is not provided. In some embodiments, the mandrel 21 is inserted into the bushing 22 along the direction from the first shaft portion 251 to the second shaft portion 252.

[0128] Please see Figure 1 and Figure 2 The user stretches the data cable 30 in the retractable cable module 100, causing the data cable 30 to be released, thus forming a data cable stretching action. Alternatively, the retractable cable module 100 can wind the data cable 30 so that the data cable 30 is retracted into the retractable cable module 100, thus forming a data cable retraction action.

[0129] In some embodiments, data cable actions may include data cable stretching and / or data cable retraction.

[0130] Please see Figure 6 and Figure 7 When the winding reel 20 rotates relative to the housing 10, such as the first housing 11, it can rotate about the rotation axis, thereby causing the bushing 22 to rotate relative to the spindle 21. This further causes the follower conductive member 23 to rotate about the rotation axis, rotating relative to the fixed conductive member 27, and simultaneously abutting against each other to achieve electrical connection. For example, the detection element 28 and the trigger element 29 abut against each other to achieve electrical connection. In some embodiments, during the stretching or retraction of the data line 30, the first detection element 281, such as the first contact portion 2811, and the trigger element 29 intermittently contact each other. In some embodiments, during the stretching or retraction of the data line 30, the second detection element 282, such as the second contact portion 2821, and the trigger element 29 intermittently contact each other.

[0131] Furthermore, the data cable 30, the follower conductive member 23, and the fixed conductive member 27 are sequentially electrically connected, and the fixed conductive member 27 can be further electrically connected to the circuit board 13 or an external wiring. In some embodiments, the first detection element 281, such as the first external connection portion 2812, can be electrically connected to the circuit board or an external wiring. In some embodiments, the second detection element 282, such as the second contact portion 2821, can be electrically connected to the circuit board or an external wiring.

[0132] Please combine Figure 7 , Figure 8 and Figure 9 When the follower conductive member 23 rotates relative to the fixed conductive member 27, the trigger member 29 can be electrically connected to the first detection member 281, for example, the first contact portion 2811, or the second detection member 282, for example, the second contact portion 2821. This enables the first detection member 281, for example, the first external portion 2812, or the second detection member 282, for example, the second contact portion 2821, to output a detection signal. Furthermore, the detection signal can characterize the data line operation, thereby realizing the detection of the data line operation.

[0133] In some embodiments, when the bushing 22 rotates relative to the spindle 21, the contact between one of two adjacent detection elements 28 (e.g., the first detection element 281) and the trigger element 29 is changed to the other (e.g., the second detection element 282) contacting the trigger element 29.

[0134] Furthermore, interruptions and connections in the electrical signal can be made, and the data line operation can be detected by observing the pattern of these interruptions and connections. Alternatively, the data line operation can also be detected based on the timing of the electrical signal connection and disconnection.

[0135] In some embodiments, the rotation direction may include a first rotation direction in which the winding reel 20 winds the data cable 30, and a second rotation direction in which the winding reel 20 releases the data cable 30. That is, the first rotation direction corresponds to the data cable retraction action, and the second rotation direction corresponds to the data cable stretching action.

[0136] Furthermore, in a further embodiment, the detection signal indicating the data line retraction action can simultaneously indicate the first rotation direction.

[0137] Furthermore, in a further embodiment, the detection signal indicating the data line stretching action can simultaneously indicate the second rotation direction.

[0138] In some embodiments, different data line actions can result in variations in the polarity of the detection signal, the current intensity (which can characterize either signal strength or current magnitude), the duration, and the interval between detection signals. These characteristics can be altered based on the design of the winding reel 20. Furthermore, the data line action can be determined based on the detection signal. Consequently, data line action characteristic data can be detected.

[0139] In some embodiments, the positive or negative polarity of a signal can be detected to determine data line operation. In some embodiments, the detected signal may include a sequence of sub-signals, and the data line operation can be determined by a sequence of positive or negative polarity formed by the positive and negative polarities of each sub-signal in the sub-signal sequence. In some embodiments, the detected signal may include a sequence of sub-signal sequences, and the data line operation can be determined by a sequence of durations formed by the durations of each sub-signal in the sub-signal sequence. In some embodiments, the detected signal includes a sequence of sub-signal sequences, and the data line operation can be determined by a sequence of interval durations formed by the intervals between adjacent sub-signals in the sub-signal sequence. In some embodiments, the detected signal includes a sequence of sub-signal sequences, and the data line operation can be determined by a sequence of signal strengths formed by the signal strengths of each sub-signal in the sub-signal sequence.

[0140] Please see Figure 1 , Figure 8 and Figure 9During the stretching or retraction of the data line 30, the detection element 28, such as the first detection element 281, and the trigger element 29 are in intermittent contact, which can cause the detection signal to intermittently form a sub-signal sequence.

[0141] Please see Figure 1 , Figure 8 and Figure 9 During the stretching or retraction of the data line 30, the detection element 28, such as the second detection element 282, and the trigger element 29 intermittently contact each other, which can cause the detection signal to intermittently form a sub-signal sequence.

[0142] Please see Figure 1 , Figure 8 and Figure 9 When the winding reel 20, for example, the bushing 22, rotates one revolution, the length of the second contact portion 2821 of the trigger member 29 contacting the detection member 28, for example, the second detection member 282, is less than the length of the first contact portion 2811 of the trigger member 29 contacting the detection member 28, for example, the first detection member 281, so that the duration of each sub-signal in the detection signal can be adjusted. Of course, when the winding reel 20, for example, the bushing 22, rotates one revolution, the length of the second contact portion 2821 of the trigger member 29 contacting the detection member 28, for example, the second detection member 282, can also be greater than the length of the first contact portion 2811 of the trigger member 29 contacting the detection member 28, for example, the first detection member 281.

[0143] Please see Figure 8 and Figure 9 The first detection element 281, such as the first contact portion 2811, and the second detection element 282, such as the second contact portion 2821, can be spaced apart along the lateral circumference of the mandrel 21. Of course, the first detection element 281, such as the first contact portion 2811, and the second detection element 282, such as the second contact portion 2821, can be spaced apart along the axial direction of the mandrel 21.

[0144] In some embodiments, in order to achieve signal detection, external parts such as the first external part 2812 and the second external part 2822 may be connected to other detection circuits, and the detection circuits may be disposed on the circuit board 13.

[0145] Please see Figure 10 , Figure 11 and Figure 12 , Figure 10 This is a circuit diagram related to the first detection element 281 in some embodiments of this application. Figure 11 for Figure 6 The diagram shown illustrates the interaction of the detection element 28 and the trigger element 29 in some embodiments, as well as the waveform of the detection signal generated during interaction. Figure 12 for Figure 6The illustrated embodiment shows a schematic diagram of the cooperation between the detection element 28 and the trigger element 29 in some embodiments, and a waveform diagram of the detection signal generated during cooperation. The first detection element 281, for example, the first external portion 2812, can be connected to a high-level signal source VCC through a first resistor R1. Therefore, when the trigger element 29 is not in contact with the first detection element 281, for example, the first contact portion 2811, the first detection element 281, for example, the first external portion 2812, is at a high-level signal, and thus the output detection signal is a high-level signal. When the trigger element 29 contacts the first detection element 281, for example, the first contact portion 2811, it pulls down the level signal at the first detection element 281, for example, the first external portion 2812, to a low-level signal, and thus the output detection signal is a low-level signal. Further, through the arrangement of high and low level signals (e.g., Figure 11 As shown in the waveform diagram of the detection signal, specifically, point A refers to the high-level signal of the first detection element 281, realizing the detection of data line operation. In some embodiments, when the trigger element 29 is connected to the fifth conductive element 2315, such as the grounding element (the fifth conductive element 2315, such as the grounding element, can be connected to the data line 30, such as the negative power line, and can be electrically connected to the negative power supply on the circuit board 13, i.e., grounded), the level signal at the first detection element 281, such as the first external portion 2812, can be pulled down.

[0146] Please see Figure 12 and Figure 13 , Figure 13 This is a circuit diagram related to the second detection element 282 in some embodiments of this application. The second detection element 282, for example, the second external portion 2822, can be connected to a high-level signal source VCC via a second resistor R2. Therefore, when the trigger 29 is not in contact with the second detection element 282, for example, the second contact portion 2821, the second detection element 282, for example, has a high-level signal at the second contact portion 2821, and thus the output detection signal is a high-level signal. When the trigger 29 contacts the second detection element 282, for example, the second contact portion 2821, the level signal at the second detection element 282, for example, the second external portion 2822, is pulled down to a low-level signal, and thus the output detection signal is a low-level signal. Further, through the arrangement of high and low level signals, the detection of data line operation (e.g., ...) is achieved. Figure 12 As shown in the waveform diagram of the detection signal, specifically, point B refers to the high-level signal of the second detection element 282. In some embodiments, when the trigger element 29 is connected to the fifth conductive element 2315, for example, the grounding element (the fifth conductive element 2315, for example, the grounding element, can be connected to the data line 30, for example, the negative power line, and can be electrically connected to the negative power terminal on the circuit board 13, i.e., grounded), the level signal at the second detection element 282, for example, the second external portion 2822, can be pulled down.

[0147] Please see Figure 11 Based on the arrangement of high and low level signals, the waveform of the detection signal in the diagram shows that data line 30 is in the process of data line operation.

[0148] Please see Figure 12 Based on the arrangement of high and low level signals, the waveform of the detection signal in the diagram shows that the data line 30 is in the process of data line operation. Specifically, the trigger 29 first contacts the first detection element 281, then contacts the second detection element 282, and then rotates towards the fourth conductor 274.

[0149] In a further embodiment, the trigger 29 can connect the fifth conductive element 2315, such as a grounding element, to the fourth conductive element 274, so as to further electrically connect the negative power supply terminal on the circuit board 13, i.e., ground, through the fourth conductive element 274.

[0150] In a further embodiment, the trigger 29 may connect the fifth conductive element 2315, such as a grounding element, to the mounting shaft 25 to further electrically connect the negative power supply terminal on the circuit board 13, i.e., ground, via the mounting shaft 25.

[0151] In some embodiments, the high-level signal source VCC can output a 5V high-level signal, a 3.3V high-level signal, or even a high-level signal with other voltage values, which will not be elaborated further. In some embodiments, in order to distinguish it from the data line 30, the voltage value of the high-level signal output by the high-level signal source VCC is different from the voltage value of the high-level signal at the positive power supply line of the data line 30.

[0152] Understandably, the cooperation between the detection element 28 and the trigger element 29 enables the detection of data line movement. However, the cooperation between the detection element 28 and the trigger element 29 is not limited to detecting data line movement through electrical connection. For example, the detection element 28 can be a Hall element, and the trigger element 29 can be a magnetic element (a structure capable of generating a magnetic field). Of course, other methods are also possible. For instance, the light source may be blocked or unblocked by the trigger element 29, allowing the detection element 28 to acquire light. Alternatively, the detection element 28, for example, can be a coil, and the trigger element 29, for example, can generate electricity through cooperation.

[0153] In some embodiments, when the follower conductive member 23 rotates relative to the fixed conductive member 27, the detection element 28, such as a Hall element, can be triggered by the trigger element 29, such as a magnetic element, thereby generating a detection signal that can characterize the operation of the data line. In some embodiments, the detection element 28, such as a Hall element, is disposed on the spindle 21, and the trigger element 29, such as a magnetic element, is disposed on the bushing 22. In some embodiments, the detection element 28, such as a Hall element, is disposed on the bushing 22, and the trigger element 29, such as a magnetic element, is disposed on the spindle 21. In a further embodiment, the detection element 28, such as a Hall element, can be electrically connected to conductors such as the first conductor 271, the second conductor 272, the third conductor 273, the fourth conductor 274, and the fifth conductor through conductive elements 231, such as the first conductive element 2311, the second conductive element 2312, the third conductive element 2313, the fourth conductive element 2314, and the fifth conductive element 2315, so as to output a detection signal. Even the detection element 28, such as the Hall element, can be electrically connected to the mounting shaft 25 via conductive elements 231, such as the first conductive element 2311, the second conductive element 2312, the third conductive element 2313, the fourth conductive element 2314, the fifth conductive element 2315, etc., to output a detection signal.

[0154] In some embodiments, the detection element 28, such as a Hall element, may be disposed on the periphery of the spindle 21.

[0155] In some embodiments, the bushing 22 is provided with a trigger element 29, such as a magnetic element, on the surface of the side of the mandrel 21.

[0156] In some embodiments, the trigger 29, for example a magnetic element, is disposed on the top side of the bushing 22 (on one side along the axial direction of the mandrel 21).

[0157] Understandably, the number of trigger elements 29, such as magnetic elements, can be multiple, each with a different maximum magnetic field strength and / or duration acting on the detection element 28, such as a Hall element. This allows the detection signal generated by the trigger element 29, such as the magnetic element, to detect the data line operation. Of course, in some embodiments, the number of detection elements 28, such as Hall elements, can also be multiple. Furthermore, the arrangement and / or spacing of the detection elements 28, such as Hall elements, can vary.

For instance, the division of modules or units is only a logical functional division, and there may be other division methods in actual implementation.
