Description

Technical Field

[0001] This application relates to the technical field of accessories for electronic devices, and in particular to a retractable cable module. Background Technology

[0002] To facilitate the storage of data cables, retractable data cables have appeared on the market. When not in use, the data cable can be stored inside the casing, and when in use, the data cable can be pulled out.

[0003] Existing retractable data cable modules include a housing, a retractable cable, and a winding assembly. The winding assembly is housed within the housing. A single retractable cable is mounted on the winding assembly, with both ends extending out of the housing and connected to connectors. Pulling one end of the cable outwards causes the other end to extend outwards simultaneously, and retracting one end back into the housing also causes the other end to retract inwards simultaneously. This type of retractable cable module significantly limits the flexibility of use; it cannot meet the user's need for only one end of the cable to extend while the other remains closed.

[0031] Before describing the embodiments in detail, it should be understood that this application is not limited to the detailed structures or element arrangements described below or in the accompanying drawings. This application can be implemented in other ways. Furthermore, it should be understood that the wording and terminology used herein are for descriptive purposes only and should not be construed as limiting. The terms "comprising," "including," "having," and similar expressions used herein mean to include the items listed thereafter, their equivalents, and other additional items. In particular, when describing "an element," this application does not limit the number of elements to one, but may include multiple elements.

[0032] Please also refer to Figures 1 to 2As shown, this application provides a retractable cable module 15, which can be used as a data cable or applied to a charging device. The retractable cable module 15 includes a mounting housing 20 and a first cable winding structure 16, a second cable winding structure 18, and a connector 22 disposed within the mounting housing 20. The first cable winding structure 16 has a retractable first retractable cable 24, one end of which is located outside the mounting housing 20, for example, one end of the first retractable cable 24 extends out of the mounting housing 20 and is equipped with a first connector. The second cable winding structure 18 has a retractable second retractable cable 26, one end of which is located outside the mounting housing 20, for example, one end of the second retractable cable 26 extends out of the mounting housing 20 and is equipped with a second connector. The other end of the first retractable cable 24 and the other end of the second retractable cable 26 are electrically connected via the connector 22.

[0033] The guide member 22 can be located on the same side of the first winding structure 16 and the second winding structure 18. The guide member 22 includes a first guide part 30, a second guide part 32 and a connecting part 36. The other end of the first telescopic cable 24 is electrically connected to the first guide part 30 through the first adapter 60 of the first winding structure 16. The other end of the second telescopic cable 26 is electrically connected to the second guide part 32 through the second adapter 64 of the second winding structure 18. The connecting part 36 is electrically connected to the first guide part 30 and the second guide part 32 respectively.

[0034] This application integrates the first winding structure 16, the second winding structure 18, and the guide 22 into a mounting housing 20 to form a telescopic cable module 15. The two winding structures are independent of each other. The first telescopic cable 24 and the second telescopic cable 26 are connected by the guide 22 and can extend and retract independently. The first telescopic cable 24 and the second telescopic cable 26 are always electrically connected, which meets the user's needs for one-end extension, two-end extension, and adjustable extension length of a single telescopic cable. This improves the functionality of the telescopic cable module 15 and broadens the application scenarios and scope of the product.

[0035] In this embodiment, the first retractable cable 24 and the second retractable cable 26 are both data cables, and the first connector and the second connector can be USB connectors, Type-C connectors, Lightning connectors, etc. For example, the first connector can connect to the charging plug of a charger, and the second connector can connect to the device to be charged, such as a mobile phone, tablet computer, laptop computer, electric shaver, digital camera, or other rechargeable device. In other embodiments, the first connector can also be an electrical connector 17. For example, the retractable cable module 15 is applied to a charging device, which includes a charging plug. The electrical connector 17 is connected to the charging plug, and this connection includes, for example, a mechanical connection and an electrical connection to the circuit elements of the charging plug 14. Furthermore, the charging device can also include a device body, and the retractable cable module 15 can be installed inside the device body. The device body can be equipped with components such as a bracket, a battery cell, and a main circuit board 38, which can achieve current modulation, or charge the device to be charged using the battery cell when the charging plug is not connected to an external power source. The external power supply components mentioned herein can include the battery cell, the main circuit board, and the pin header connector.

[0036] In the illustrated embodiment, as Figure 1 As shown, the telescopic cable module 15 is generally square, and it has three intersecting directions: a first direction, b second direction, and c third direction. Preferably, the first direction a is the length direction of the telescopic cable module 15, the second direction b is the thickness direction of the telescopic cable module 15, and the third direction c is the width direction of the telescopic cable module 15. Therefore, the first direction a, the second direction b, and the third direction c are perpendicular to each other.

[0037] Please also refer to Figures 4 to 5 As shown, the first winding structure 16 and the second winding structure 18 are arranged side by side along the first direction a. Both the first winding structure 16 and the second winding structure 18 achieve the extension and retraction of the telescopic line by rotation. The rotation axes of the first winding structure 16 and the second winding structure 18 are parallel to the second direction b.

[0038] The guide member 22 is disposed on one side of the first winding structure 16 and the second winding structure 18 along the second direction b. The guide member 22 can be a conductive circuit board fixed relative to the mounting housing 20. Optionally, the guide member 22 is fixedly connected to the mounting housing 20, for example, by means of adhesive bonding, screw fixing, etc.

[0039] In the illustrated embodiment, as Figure 8As shown, the connector 22 includes a connecting bridge 34. A first connecting portion 30 and a second connecting portion 32 are respectively connected to both ends of the connecting bridge 34. The connecting bridge 34 spans the surface of the first winding structure 16 and the second winding structure 18 on the same side, forming a bridge-type connection structure. A connecting portion 36 is connected to the second connecting portion 32. The first connecting portion 30, the second connecting portion 32, the connecting bridge 34, and the connecting portion 36 are, for example, integrally formed. In this embodiment, the first connecting portion 30, the second connecting portion 32, the connecting bridge 34, and the connecting portion 36 are disposed on the same circuit board. The connecting portion 36 is used for electrical connection with an external power supply component, such as a main circuit board 38, and is electrically connected to the main circuit board 38. The width of the connecting bridge 34 can be the same as or similar to the width of the first connecting portion 30 and the second connecting portion 32.

[0040] Furthermore, a guide end 50 is formed at the end of the connecting portion 36 opposite to the second guide portion 32. The guide end 50 is, for example, a welded structure, and is exposed outside the mounting housing 20 to facilitate electrical connection with the main circuit board 38, while avoiding interference with the rotation of the second coil structure 18. The guide end 50 includes a first terminal and a second terminal. The first guide portion 30 is electrically connected to the first terminal via the connecting bridge 34 and the first conductor within the connecting portion 36. The second guide portion 32 is electrically connected to the second terminal via the second conductor within the connecting portion 36, thereby ensuring that the first telescopic cable 24 and the second telescopic cable 26 are always electrically connected, and always electrically connected to the main circuit board 38. The first and second conductors are, for example, conductive materials such as copper foil, and are independent of each other, for example, spaced apart to avoid short circuits or mutual interference. The first and second conductors can each have multiple sub-conductors, which are independent of each other, for example, spaced apart to avoid short circuits or mutual interference.

[0041] Furthermore, the conductive terminal 50 includes a first solder portion corresponding to the first terminal and a second solder portion corresponding to the second terminal. The plurality of first solder portions of the conductive terminal 50 are electrically connected to the plurality of first annular conductive portions 40 via a first conductor, and the plurality of second solder portions of the conductive terminal 50 are electrically connected to the plurality of second annular conductive portions 42 via a second conductor.

[0042] Specifically, both the first conductive portion 30 and the second conductive portion 32 are circular, and their diameters are the same. The connecting bridge 34 is a rectangular strip, and its length extends in a direction parallel to, for example, the first direction a. Furthermore, the diameters of both the first conductive portion 30 and the second conductive portion 32 are larger than the width of the connecting bridge 34 to avoid it occupying an excessively large area. On the side of the first conductive portion 30 near the first winding structure 16, multiple first annular conductive portions 40 are spaced apart. These first annular conductive portions 40 are, for example, metal sheets. The multiple first annular conductive portions 40 are concentric and spaced apart, meaning their diameters gradually increase outwards from the center of the first conductive portion 30. On the side of the second conductive portion 32 near the second winding structure 18, multiple second annular conductive portions 42 are spaced apart. These multiple second annular conductive portions 42 are concentric and spaced apart, meaning their diameters gradually increase outwards from the center of the second conductive portion 32.

[0043] In one embodiment where multiple first annular conductive parts 40 and multiple second annular conductive parts 42 are electrically connected, for an embodiment with a charging plug that connects to AC power (an embodiment that converts AC power to DC power), the first annular conductive parts 40 and the second annular conductive parts 42 are respectively connected to different solder holes of the conductive end 50 through different conductors. This is because the DC power input through the charging plug may need to be converted to different specifications of DC power by the charging module on the main circuit board 38 before transmitting power to the DC output terminal. For example, the charging plug may input 15V, 3A DC power, while the device connected to the DC output terminal only needs 9V, 2A DC power, thus requiring conversion. The overall transmission path can be understood as: charging plug → first retractable cable → first annular conductive part → connecting bridge conductor → conductive end → main circuit board charging module → conductive end → connecting bridge conductor → second annular conductive part → second retractable cable → DC output terminal. The DC output terminal is, for example, the data connector of the second retractable cable 26 located at one end of the retractable cable module 15.

[0044] Furthermore, the first conductive portion 30 has a plurality of radially spaced first insulating ring portions 44 on the side near the first winding structure 16, with each first annular conductive portion 40 disposed between two adjacent first insulating ring portions 44. The second conductive portion 32 has a plurality of radially spaced second insulating ring portions 46 on the side near the second winding structure 18, with each second annular conductive portion 42 disposed between two adjacent second insulating ring portions 46. Both the first insulating ring portions 44 and the second insulating ring portions 46 are made of insulating material, so that the plurality of annular conductive portions are mutually insulated to prevent short circuits.

[0045] The widths of both the first insulating ring 44 and the second insulating ring 46 are set to be greater than 0.3 mm. This is to increase the insulation distance between two adjacent annular conductive parts and improve safety. When the widths of the first insulating ring 44 and the second insulating ring 46 are less than 0.3 mm, problems such as short circuits due to excessive distance may occur.

[0046] Furthermore, the plurality of first insulating ring portions 44 include an innermost first inner ring portion and a plurality of first spacers surrounding the innermost first inner ring portion. The width of the innermost first ring portion is greater than the width of the spacers surrounding the innermost first inner ring portion. For example, the width of the innermost first ring portion is greater than 0.35 mm, the width of the spacers is greater than 0.3 mm, and the width of the innermost first ring portion is greater than the width of the spacers. The plurality of second insulating ring portions 46 include an innermost second inner ring portion and a plurality of second spacers surrounding the innermost second inner ring portion. The width of the innermost second ring portion is greater than the width of the spacers surrounding the innermost second inner ring portion. For example, the width of the innermost second ring portion is greater than 0.35 mm, the width of the spacers is greater than 0.3 mm, and the width of the innermost second ring portion is greater than the width of the spacers. Setting the width of the inner ring portion to be greater than the width of the spacers is to increase the structural strength of the inner ring portion and prevent deformation of the inner ring portion from causing frictional damage to the turntable shaft of the telescopic wire module.

[0047] Preferably, the widths of the first annular conductive portion 40 and the second annular conductive portion 42 are both set to be greater than 0.8 mm, and more preferably 1 mm, in order to allow the annular conductive portions to carry a larger current and meet the requirements of high-power designs. When the widths of the first annular conductive portion 40 and the second annular conductive portion 42 are less than 0.8 mm, the maximum current that can flow will be smaller, which will not meet the requirements of high-power applications.

[0048] In some embodiments, among the plurality of first annular conductive portions 40, the outermost first annular conductive portion 40 is one of the positive and negative terminals of a power supply, the innermost first annular conductive portion 40 is the other of the positive and negative terminals of a power supply, and the middle first annular conductive portion 40 is a signal line. Similarly, among the plurality of second annular conductive portions 42, the outermost second annular conductive portion 42 is one of the positive and negative terminals of a power supply, the innermost second annular conductive portion 42 is the other of the positive and negative terminals of a power supply, and the middle second annular conductive portion 42 is a signal line. Preferably, among the plurality of first annular conductive portions 40, two first annular conductive portions 40 are positive terminals of a power supply, and two first annular conductive portions 40 are negative terminals of a power supply. Among the plurality of second annular conductive portions 42, two second annular conductive portions 42 are positive terminals of a power supply, and two second annular conductive portions 42 are negative terminals of a power supply.

[0049] In this embodiment, the charging plug is equipped with an AC module, which is electrically connected to the plug pins to convert the AC input into DC power. The positive and negative conductive rings of the first annular conductive portion 40 are connected to the positive and negative terminals of the AC module output via the positive and negative wires of the first telescopic wire 24, respectively. For example, five first annular conductive portions 40 are provided. The two outermost first annular conductive portions 40 are connected to one of the positive and negative terminals of the AC module, the two innermost first annular conductive portions 40 are connected to the other of the positive and negative terminals of the AC module, and the middle first annular conductive portion 40 is connected to the signal line of the charging plug. That is, the positions of the coils connecting the positive and negative terminals in the multiple first annular conductive portions 40 can be interchanged. The second coil structure 18 extends out of the telescopic cable module 15 and is provided with a data connector 48, that is, the second connector is a data connector 48. The data connector 48 can be used to connect the device to be charged. Five second annular conductive parts 42 are provided. The five second annular conductive parts 42 are connected from the outside to the inside to the negative terminal, D- line, CC line, D+ line and positive terminal of the data connector 48 respectively.

[0050] In the illustrated embodiment, the conductive end 50 is exposed outside the mounting housing 20 to facilitate electrical connection with the main circuit board 38. Specifically, the connecting bridge 34 extends along the length of the mounting housing 20, the mounting housing 20 has a second cable outlet 54 corresponding to the second cable winding structure 18, and the mounting housing 20 has an opening 55 spaced apart from the second cable outlet 54 along its width. The connecting portion 36 is inclined relative to the connecting bridge 34 and passes through the opening 55. The conductive end 50 is formed at the end of the connecting portion 36, and the connecting portion 36 passes through the opening 55 so that the conductive end 50 is exposed outside the mounting housing 20. For example, the conductive end 50 is exposed through the opening 55 and protrudes outside the mounting housing 20 to facilitate electrical connection with the main circuit board 38. Preferably, the conductive end 50 and the main circuit board 38 are fixed and electrically connected by a pin header connector 52 to enhance the connection strength and ensure a stable electrical connection.

[0051] The second cable outlet 54 is located at the junction of a long sidewall and a short sidewall of the mounting housing 20. This location is, for example, a corner at one end of the mounting housing 20 along its length. Both the long and short sidewalls are circumferential sidewalls along the thickness direction of the mounting housing 20. The connecting portion 36 is inclined relative to the extension direction of the connecting bridge 34, for example, the connecting portion 36 is inclined away from the extension direction of the connecting bridge 34. Preferably, the angle between the connecting portion 36 and the connecting bridge 34 is an obtuse angle, so that the guide end 50 is located on the opposite side from the second cable outlet 54, avoiding interference between the guide end 50 and the second telescopic cable 26.

[0052] Furthermore, the conductive end 50 includes eight welding holes arranged in two rows at intervals, with four welding holes in each row, and the two rows of welding holes are aligned and spaced apart. The first annular conductive portions 40 of the two outer rings are electrically connected to one of the welding holes, the first annular conductive portions 40 of the two inner rings are electrically connected to the other welding hole, and the middle first annular conductive portion 40 and five second annular conductive portions 42 are electrically connected to the remaining six welding holes, and a notch 56 is formed on the side of the conductive end 50.

[0053] It should be noted that the first conductive part 30 connects the positive terminal, negative terminal, and signal line of the AC module. Normally, to save costs, only three first annular conductive parts 40 are needed. However, existing molds are configured to have five annular conductive parts. If only three annular conductive parts are used, a separate mold needs to be made, which leads to higher costs. Therefore, this application sets five first annular conductive parts 40, with two first annular conductive parts 40 connected to the positive terminal and two first annular conductive parts 40 connected to the negative terminal. This design increases the cross-sectional area of ​​the wires connecting the positive and negative terminals, allowing for a larger current to meet high-power designs and enhance circuit stability. Furthermore, it eliminates the need for additional molds to manufacture molds for three annular conductive parts, thereby reducing production costs. Furthermore, since the five first annular conductive parts 40 and the five second annular conductive parts 42 need to be connected to 10 welding holes, but two first annular conductive parts 40 are connected to the positive electrode and two first annular conductive parts 40 are connected to the negative electrode, only eight welding holes are needed. The width of the conductive end 50 can be reduced by setting a notch 56, thereby reducing the volume occupied.

[0054] In this embodiment, please also refer to Figures 6 to 7 As shown, the first winding structure 16 includes a first turntable 58 and a first adapter 60 fixedly disposed on the side of the first turntable 58 near the guide member 22. The first turntable 58 is rotatably disposed within the mounting housing 20. The second winding structure 18 includes a second turntable 62 and a second adapter 64 fixedly disposed on the side of the second turntable 62 near the guide member 22. The second turntable 62 is rotatably disposed within the mounting housing 20.

[0055] Specifically, the inner side of the housing wall of the mounting shell 20 extends along the second direction b to form a first rotating shaft 66 and a second rotating shaft 68. A first shaft hole 59 is provided at the center of the first turntable 58, and the first turntable 58 is rotatably fitted onto the first rotating shaft 66 through the first shaft hole 59.

A first through hole 70 is provided at the center of the first guide portion 30, and a second through hole 72 is provided at the center of the second guide portion 32. The first rotating shaft 66 passes through the first through hole 70, and the second rotating shaft 68 passes through the second through hole 72. In other embodiments, the first guide portion 30 is fixedly fitted onto the first rotating shaft 66 through the first through hole 70, and the second guide portion 32 is fixedly fitted onto the second rotating shaft 68 through the second through hole 72, thereby fixing the guide member 22 to the mounting shell 20.

[0056] Furthermore, the first adapter 60 includes a first adapter plate 74 and multiple sets of first elastic terminals 76 fixed on the side of the first adapter plate 74 near the conductor 22. The first elastic terminals 76 are electrically connected to the first telescopic wire 24, and multiple abutment portions of each set of first elastic terminals 76 elastically abut against multiple first annular conductive portions 40 in a one-to-one correspondence. Specifically, the first adapter plate 74 is circular, and the multiple sets of first elastic terminals 76 are evenly spaced along the circumference of the first adapter plate 74. For example, three sets of first elastic terminals 76 are provided, and each set of first elastic terminals 76 is provided with five spring pieces, which elastically abut against five first annular conductive portions 40 respectively. The first elastic terminals 76 are provided with a mounting base, and the five spring pieces are mounted on the mounting base. One end of the spring piece is electrically connected to the first telescopic wire 24, and the other end is electrically connected to the first annular conductive portion 40 by abutment.

The second elastic terminals 80 are electrically connected to the second telescopic wire 26, and multiple abutment portions of each set of second elastic terminals 80 elastically abut against multiple second annular conductive portions 42 in a one-to-one correspondence. Specifically, the second adapter plate 78 is circular, and the multiple sets of second elastic terminals 80 are evenly spaced along the circumference of the second adapter plate 78. For example, three sets of second elastic terminals 80 are provided, and each set of second elastic terminals 80 is provided with five spring pieces, which elastically abut against five second annular conductive portions 42 respectively. The second elastic terminals 80 are provided with a mounting base, and the five spring pieces are mounted on the mounting base.

The first wire placement groove 84 is located between the first mounting groove 82 and the first winding groove 86, and communicates with both the first mounting groove 82 and the first winding groove 86. For example, the first wire placement groove 84 is located on the bottom wall of the first mounting groove 82 and communicates with the first winding groove 86, for example, through an opening. The first adapter 60 is fixed in the first mounting groove 82. For example, the first mounting groove 82 has a positioning post, and the first adapter plate 74 has a corresponding positioning hole. The positioning and installation of the first adapter 60 can be achieved through the positioning engagement of the positioning post and the positioning hole. The first telescopic wire 24 is wound within the first winding groove 86, and one end of the first telescopic wire 24 located within the mounting housing 20 extends into the first wire placement groove 84 and is electrically connected to the first elastic terminal 76, for example, by welding, thereby achieving an electrical connection between the first telescopic wire 24 and the first conductive portion 30. Preferably, the depth of the first wire placement groove 84 is greater than the depth of the first mounting groove 82 to provide more space to accommodate the portion where the first elastic terminal 76 is welded to the first telescopic wire 24.

[0059] The second turntable 62 is provided with a second mounting groove 88, a second wire placement groove 90, and a second winding groove 92. The second winding groove 92 is located on the circumferential sidewall of the second turntable 62. The second mounting groove 88 is located on the side of the second turntable 62 near the guide member 22 and surrounds the second shaft hole 63. The second wire placement groove 90 is located between the second mounting groove 88 and the second winding groove 92, and communicates with both the second mounting groove 88 and the second winding groove 92. For example, the second wire placement groove 90 may be located on the bottom wall of the second mounting groove 88 and communicate with the second winding groove 92, for example, through an opening. The second adapter 64 is fixed in the second mounting groove 88. For example, the second mounting groove 88 has a positioning post, and the second adapter plate 78 has a corresponding positioning hole. The positioning and installation of the second adapter 64 can be achieved through the positioning engagement of the positioning post and the positioning hole. The second telescopic wire 26 is wound within the second winding groove 92, and one end of the second telescopic wire 26 located within the mounting housing 20 extends into the second wire placement groove 90 and is electrically connected to the second elastic terminal 80, for example, by welding, thereby achieving an electrical connection between the second telescopic wire 26 and the second conductive portion 32. Preferably, the depth of the second wire placement groove 92 is greater than the depth of the second mounting groove 88 to provide more space to accommodate the portion where the second elastic terminal 80 and the second telescopic wire 26 are welded.

[0060] Furthermore, a first annular wall 94 protrudes from the center of the first turntable 58 near the guide member 22, forming a first mounting groove 88. The diameter of the first guide portion 30 is set smaller than the outer diameter of the first annular wall 94 to prevent friction between the edge of the first annular wall 94 and the first guide portion 30. A second annular wall 96 protrudes from the center of the second turntable 62 near the guide member 22, forming a second mounting groove 88. The diameter of the second guide portion 32 is set smaller than the outer diameter of the second annular wall 96 to prevent friction between the edge of the second annular wall 96 and the second guide portion 32.

[0061] In the illustrated embodiment, as Figure 1 and Figure 2 As shown, the mounting housing 20 has a first cable outlet 98 corresponding to the first cable winding structure 16 and a second cable outlet 54 corresponding to the second cable winding structure 18. The first cable outlet 98 is located at one end of the mounting housing 20 for the first telescopic cable 24 to pass through. The second cable outlet 54 is located at the other end of the mounting housing 20 for the second telescopic cable 26 to pass through. Preferably, the first cable outlet 98 and the second cable outlet 54 are located on opposite sides of the mounting housing 20 along a third direction c, and the cable exit directions of the first cable outlet 98 and the second cable outlet 54 are opposite.

[0062] Please refer to Figure 4 and Figure 5 As shown, the mounting housing 20 includes a first housing 106 and a second housing connected by mating. The inner wall of the first housing 106 is provided with a first rotating shaft 66 and a second rotating shaft 68. A first winding structure 16 is rotatably sleeved on the outside of the first rotating shaft 66, and a second winding structure 18 is rotatably sleeved on the outside of the second rotating shaft 68. A guide member 22 is simultaneously sleeved on both the first rotating shaft 66 and the second rotating shaft 68. Preferably, the inner wall of the first housing 106 is provided with a receiving groove 188, and both the first rotating shaft 66 and the second rotating shaft 68 are connected to the receiving groove 188. The guide member 22 is disposed in the receiving groove 188; for example, the guide member 22 engages with the receiving groove 188 and is sleeved on the first rotating shaft 66 and the second rotating shaft 68 through a through hole.

[0063] In this embodiment, the second housing includes a first sub-housing portion 108 and a second sub-housing portion 110. The first sub-housing portion 108 and the second sub-housing portion 110 are detachably connected to the first housing 106 by means of snap-fit, screws, or other methods. A first mounting position is formed between the first sub-housing portion 108 and the first housing 106, and a first rotating shaft 66 is located at the first mounting position. A second mounting position is formed between the second sub-housing portion 110 and the first housing 106, and a second rotating shaft 66 is located at the second mounting position. A first winding structure 16 is installed between the first sub-housing portion 108 and the first housing 106, i.e., at the first mounting position. A second winding structure 18 is installed between the second sub-housing portion 110 and the first housing 106, i.e., at the second mounting position. The first sub-housing portion 108 and the second sub-housing portion 110 can be integrally formed. The advantage of integral forming is that it can reduce production molds and production processes, thereby reducing production costs. Alternatively, the first sub-shell 108 and the second sub-shell 110 can be separately configured and connected in parallel. The advantage of this separation is that the two winding structures can be installed independently, reducing the requirements for installation accuracy and facilitating individual maintenance. In the illustrated embodiment, the first sub-shell 108 and the second sub-shell 110 are separately configured.

[0064] Furthermore, the first sub-shell portion 108 and the second sub-shell portion 110 are arranged side by side along the length of the mounting shell 20. An alignment structure is provided between the first sub-shell portion 108 and the second sub-shell portion 110, connecting them. This alignment structure prevents misalignment between the first sub-shell portion 108 and the second sub-shell portion 110, serving a positioning installation function, improving installation efficiency, and also providing a foolproof effect. In other embodiments, the first sub-shell portion 108 and the second sub-shell portion 110 may not be connected.

[0065] The alignment structure can be a concave-convex fit structure. Specifically, the alignment structure includes a first arched portion 108a and a first recessed portion 108b disposed on the first sub-shell portion 108, and a second arched portion 110a and a second recessed portion 110b disposed on the second sub-shell portion 110. The first arched portion 108a and the first recessed portion 108b are disposed on the sidewalls of the first sub-shell portion 108 and the second sub-shell portion 1100 respectively, and the second arched portion 110a and the second recessed portion 110b are disposed on the sidewalls of the second sub-shell portion 110 and the first sub-shell portion 108 respectively. The first arched portion 108a and the second recessed portion 110b are positioned correspondingly and engage in a concave-convex fit, allowing the first sub-shell portion 108 and the second sub-shell portion 110 to be fitted together.

[0066] Since the first winding structure 16 and the second winding structure 18 are arranged side by side within the mounting shell 20, the mounting shell 20 needs a certain extension length, which may lead to deformation. In this embodiment, a reinforcing structure 202 is provided on the inner wall of the first shell 106 to enhance the structural strength of the mounting shell 20 in the length direction and overall, preventing deformation. Specifically, the first shell 106 includes a shell body 106a and shell sidewalls 106b connected to the periphery of the shell body 106a. The reinforcing structure 202 is disposed between the shell body 106a and the shell sidewalls 106b. For example, the reinforcing structure 202 is disposed between the first and second rotating shafts and extends on the inner surface of the shell body 106a, and at least one end of the reinforcing structure 202 is connected to the shell sidewalls 106b. The reinforcing structure 202 can be, for example, a columnar structure, a plate-like structure, or a combination of both, connecting the shell body 106a and the shell sidewalls 106b. The reinforcing structure 202 can be located in the middle of the first shell 106. When the first housing 106 and the second housing are fixed by screws, the screw holes or fixing holes can be provided on the columnar structure. The first arched portion 108a of the first sub-housing portion 108 and the second arched portion 110a of the second sub-housing portion 110 are also respectively provided with screw holes or fixing holes, so that the first sub-housing portion 108 and the second sub-housing portion 110 are fixed by the reinforcing structure 202, thereby improving the stability of the connection between the two sub-housing portions and the first housing 106.

[0067] In the illustrated embodiment, a space 201 is formed between the first winding structure 16 and the second winding structure 18 and the mounting housing 20. For example, the space 201 is formed between the first winding structure 16, the second winding structure 18 and the first housing 106. The telescopic cable module 15 includes a first locking mechanism and a second locking mechanism. The first locking mechanism is provided corresponding to the first winding structure 16, and the second locking mechanism is provided corresponding to the second winding structure 18. The first locking mechanism controls the take-up / unwinding of the first telescopic cable 24, and the second locking mechanism controls the take-up / unwinding of the second telescopic cable 26. The guide member 22, the first locking mechanism and the second locking mechanism are all disposed within the space 201, which can make reasonable use of the internal space of the mounting housing 20, making the installation of each component more compact and reducing the overall volume.

[0068] Please also refer to Figure 7 , Figure 9 and Figure 10As shown, the first locking mechanism includes a first rotating member 112 and a first sliding member 114. The first turntable 58 is provided with at least one first recess 116. The first recess 116 is provided, for example, on the outer surface of the first annular wall 94, and is formed by radially inward recessing from the outer surface of the first annular wall 94. For example, two first recesses 116 are provided, and the two first recesses 116 are respectively provided on the radially opposite sides of the first annular wall 94. The first rotating member 112 is rotatably mounted on the mounting shell 20. For example, the inner wall of the mounting shell 20 extends along the second direction b to form a first fixed shaft 118. The end of the first rotating member 112 away from the first annular wall 94 is rotatably sleeved on the first fixed shaft 118. The end of the first rotating member 112 facing the first recess 116 has a first protrusion 120 that mates with the first recess 116. The first rotating member 112 is designed with a structure that is small at both ends and large in the middle. The first sliding member 114 is slidably disposed on the mounting shell 20 and has a first protrusion 122 facing the first rotating member 112. The first protrusion 122 is, for example, cylindrical. The sliding direction of the first sliding member 114 is located in a diametrical direction of the first turntable 58. For example, the inner wall of the mounting shell 20 has a first groove 124 corresponding to the first rotating member 112. The first sliding member 114 is slidably disposed in the first groove 124. The first groove 124 extends along the radial direction of the first turntable 58, so that the first sliding member 114 can move back and forth in the radial direction of the first turntable 58. The first rotating member 112 has an annular first guide portion 126 on one side facing the first sliding member 114. The first guide portion 126 is, for example, an annular groove structure with the ends connected. The first protrusion 122 is slidably disposed in the first guide portion 126.

[0069] When the first turntable 58 rotates, the first protrusion 120 intermittently and repeatedly engages and disengages from the first recess 116. The steering driving force applied by the first recess 116 to the first protrusion 120 drives the first rotating member 112 to rotate and the first sliding member 114 to slide, so that the first protrusion 122 slides cyclically along the first guide portion 126. Specifically, the first guide portion 126 includes a first locking position 128 and a first unlocking position 130. When the first protrusion 122 is in the first unlocking position 130, the wire feeding rotation of the first turntable 58 is unlocked, and when the first turntable 58 rotates to reel in the wire, the first protrusion 122 slides and engages with the first locking position 128 to lock the first turntable 58.

[0070] Furthermore, the first locking mechanism includes two first stop members 132, which are respectively disposed on opposite sides of the first rotating member 112 in the rotation direction. The first stop members 132 are fixed to the mounting shell 20 and cooperate with the side wall of the first rotating member 132 to limit the rotation angle of the first rotating member 112 and prevent the first rotating member 112 from rotating excessively. Two first fixing seats 134 are provided on the inner wall of the mounting shell 20, and the two first stop members 132 are respectively fixedly installed on the corresponding first fixing seats 134. Preferably, the first stop members 132 are made of soft rubber, which can undergo a certain deformation and automatically reset, and can apply a spring force in the rotation direction to the first rotating member 112 when it collidees with the first rotating member 112.

[0071] Furthermore, the first guide part 126 also includes a second unlocking position 136 and a third unlocking position 138. When the first protrusion 122 is located in the first locking position 128 and the first turntable 58 rotates to release the wire, the first protrusion 122 slides to the second unlocking position 136 and unlocks the wire release rotation of the first turntable 58. When the first protrusion 122 is located in the second unlocking position 136 and the first turntable 58 rotates to retract the wire, the first protrusion 122 slides to the third unlocking position 138 and unlocks the wire retraction rotation of the first turntable 58. When the first protrusion 122 is located in the third unlocking position 138 and the first turntable 58 rotates to release the wire, the first protrusion 122 slides to the first unlocking position 130.

[0072] Preferably, the sidewalls of the first locking position 128, the first unlocking position 130, the second unlocking position 136, and the third unlocking position 138 are all arc-shaped structures to facilitate the sliding switching of the first protrusion 122 between multiple positions. A first guide protrusion 140 is also provided between the first locking position 128 and the first unlocking position 130. The first guide protrusion 140 is used to guide the first protrusion 122 to slide between the first unlocking position 130 and the first locking position 128. Understandably, the first guide protrusion 140 is provided to assist in guiding the sliding of the first protrusion 122, ensuring that the first protrusion 122 can accurately fall into the first locking position 128, preventing the first protrusion 122 from sliding directly past the first locking position 128, thereby ensuring that the winding rotation of the first turntable 58 is fixed.

[0073] In this embodiment, the first winding structure 16 includes a first reset member 142, which is, for example, a torsion spring. One end of the first reset member 142 is driven to be connected to the first turntable 58, and the other end is fixedly connected to the mounting shell 20. For example, the first reset member 142 is arranged in a ring between the first rotating shaft 66 and the first telescopic line 24. One end of the first reset member 142 is fixedly connected to the first rotating shaft 66, and the other end is fixedly connected to the side wall of the first winding groove 86, so as to continuously provide the driving force for the first turntable 58 to rotate for winding.

[0074] Similarly, the second locking mechanism includes a second rotating member 144 and a second sliding member 146. The second turntable 62 is provided with at least one second recess 148. The second recess 148 is provided, for example, on the outer surface of the second annular wall 96, and is formed by radially inward recessing from the outer surface of the second annular wall 96. For example, two second recesses 148 are provided, respectively located on radially opposite sides of the second annular wall 96. The second rotating member 144 is rotatably mounted on the mounting housing 20. For example, the inner wall of the mounting housing 20 extends along the second direction b to form a second fixed shaft. The end of the second rotating member 144 away from the second annular wall 96 is rotatably sleeved on the second fixed shaft. The end of the second rotating member 144 facing the second recess 148 has a second protrusion 152 that mates with the second recess 148. The second rotating member 144 is designed with a structure that is small at both ends and large in the middle. The second sliding member 146 is slidably mounted on the mounting housing 20 and is provided with a second protrusion 154. The second protrusion 154 is, for example, cylindrical. The sliding direction of the second sliding member 146 is located in a diametrical direction of the second turntable 62. For example, a second groove 156 is provided on the inner wall of the mounting housing 20 corresponding to the second rotating member 144. The second sliding member 146 is slidably disposed in the second groove 156. The second groove 156 extends along the radial direction of the second turntable 62, so that the second sliding member 146 can move back and forth in the radial direction of the second turntable 62. The second rotating member 144 is provided with an annular second guide portion 158 facing the second sliding member 146. The second guide portion 158 is, for example, an annular groove structure with the ends connected. The second protrusion 154 is slidably disposed in the second guide portion 158.

[0075] When the second turntable 62 rotates, the second protrusion 152 intermittently and repeatedly engages and disengages from the second recess 148. The steering driving force applied by the second recess 148 to the second protrusion 152 drives the second rotating member 144 to rotate and the second sliding member 146 to slide, so that the second protrusion 154 slides cyclically along the second guide portion 158. Specifically, the second guide portion 158 includes a second locking position 160 and a fourth unlocking position 162. When the second protrusion 154 is in the fourth unlocking position 162, the wire feeding rotation of the second turntable 62 is unlocked, and when the second turntable 62 rotates to reel in the wire, the second protrusion 154 slides and engages with the second locking position 160 to lock the second turntable 62.

[0076] Furthermore, the second locking mechanism includes two second stop members 164, which are respectively disposed on opposite sides of the second rotating member 144 in the rotation direction. The second stop members 164 are fixed to the mounting shell 20 and cooperate with the side wall of the second rotating member 144 to limit the rotation angle of the second rotating member 144 and prevent the second rotating member 144 from rotating excessively. Two second fixing seats 166 are provided on the inner wall of the mounting shell 20, and the two second stop members 164 are respectively fixedly installed on the corresponding second fixing seats 166. Preferably, the second stop members 164 are made of soft rubber, which can undergo a certain deformation and automatically reset, and can apply a spring force in the rotation direction to the second rotating member 144 when it collidees with the second rotating member 144.

[0077] Furthermore, the second guide part 158 ​​also includes a fifth unlocking position 168 and a sixth unlocking position 170. When the second protrusion 154 is located in the second locking position 160 and the second turntable 62 rotates to release the wire, the second protrusion 154 slides to the fifth unlocking position 168 and unlocks the wire release rotation of the second turntable 62. When the second protrusion 154 is located in the fifth unlocking position 168 and the second turntable 62 rotates to retract the wire, the second protrusion 154 slides to the sixth unlocking position 170 and unlocks the wire retraction rotation of the second turntable 62. When the second protrusion 154 is located in the sixth unlocking position 170 and the second turntable 62 rotates to release the wire, the second protrusion 154 slides to the fourth unlocking position 162.

[0078] Preferably, the sidewalls of the second locking position 160, the fourth unlocking position 162, the fifth unlocking position 168, and the sixth unlocking position 170 are all arc-shaped structures to facilitate the sliding switching of the second protrusion 154 between multiple positions. A second guide protrusion 172 is also provided between the second locking position 160 and the fourth unlocking position 162. The second guide protrusion 172 is used to guide the second protrusion 154 to slide between the fourth unlocking position 162 and the second locking position 160. Understandably, the second guide protrusion 172 is provided to assist in guiding the sliding of the second protrusion 152, ensuring that the second protrusion 152 can accurately fall into the second locking position 160, preventing the second protrusion 152 from sliding directly past the second locking position 160, thereby ensuring that the winding rotation of the second turntable 62 is fixed.

[0079] In this embodiment, the second winding structure 18 includes a second reset member 174, which is, for example, a torsion spring. One end of the second reset member 174 is driven to the second turntable 62 and the other end is fixedly connected to the mounting shell 20. For example, the second reset member 174 is arranged in a ring between the second rotating shaft 68 and the second telescopic line 26. One end of the second reset member 174 is fixedly connected to the second rotating shaft 68 and the other end is fixedly connected to the side wall of the second winding groove 92 to continuously provide the driving force for the second turntable 62 to rotate for winding.

[0080] In summary, this application provides a retractable cable module, including a mounting housing and a first cable winding structure, a second cable winding structure, and a guide member disposed within the mounting housing. The guide member includes a first guide portion, a second guide portion, and connecting portions electrically connected to both. The first cable winding structure has a retractable first cable, one end of which is located outside the mounting housing and the other end is electrically connected to the first guide portion. The second cable winding structure has a retractable second cable, one end of which is located outside the mounting housing and the other end is electrically connected to the second guide portion. This application integrates two cable winding structures and a guide member into a single mounting housing to form a retractable cable module. The two cable winding structures are independent of each other, and the first and second cable windings are connected by the guide member and can independently extend and retract, meeting user needs such as one-end extension, two-end extension, and adjustable extension length of a single cable. This improves the functionality of the retractable cable module and broadens the application scenarios and scope of the product.
