Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and in particular to a multifunctional telescopic cable device. Background Technology

[0002] Charging cables or data cables are typically used in environments with long-term power supply, such as homes and office areas; however, for outdoor charging or data transmission needs, existing charging cables or data cables are not portable enough and are not convenient to store, especially as users have an increasing need for adjustable length of charging cables or data cables.

[0003] In related technologies, charging cables or data cables have limited functionality, and the length of the transmission line is not flexible enough to meet diverse usage needs. Utility Model Content

[0004] This application provides a multi-functional retractable cable that can independently charge electrical devices without a power source, and can also independently adjust the winding and unwinding of the first and second transmission lines, thus improving the convenience and flexibility of the multi-functional retractable cable.

[0005] This application provides a multi-functional retractable cable, which includes a housing, a transmission line assembly, a rotating component, and a charging module. The housing has an accommodating space. The transmission line assembly includes at least a first transmission line and a second transmission line, which are electrically connected. Both the first and second transmission lines include an interface end for connecting to a power supply or a device. The rotating component is disposed within the accommodating space and includes at least a first wheel core and a second wheel core. The first wheel core rotates relative to the housing to wind up or unwind the first transmission line. The second wheel core rotates relative to the housing to wind up or unwind the second transmission line, and the first and second wheel cores rotate relative to the housing, respectively. The charging module is disposed within the accommodating space and is capable of storing electrical energy and / or charging a device. The charging module is electrically connected to the transmission line assembly.

[0006] The multi-functional retractable cable provided in this application reduces the problem of tangling between the first and second transmission lines because the first and second transmission lines are wound around different reel cores. Since the first and second reel cores can rotate independently relative to the housing, with the rotation of the first reel core corresponding to the winding or unwinding of the first transmission line and the rotation of the second reel core corresponding to the winding or unwinding of the second transmission line, independent winding and unwinding of the first and second transmission lines is possible. This allows for independent adjustment of the first and second transmission lines without interference, enabling users to adjust the first and / or second transmission lines individually according to their needs, thereby meeting diverse user requirements and improving the product's versatility. Because the charging module can store electrical energy and charge the device, and the transmission line assembly is also electrically connected to the charging module, the multi-functional retractable cable provided in this application can independently charge the device even when there is no power supply, thus improving convenience. Therefore, the multi-functional retractable cable provided in this application can independently charge the device even without power and can independently adjust the winding and unwinding of the first and second transmission lines, improving the convenience and flexibility of the multi-functional retractable cable.

The wireless charging module is electrically connected to the battery assembly through the second circuit board, and the battery assembly can provide electrical energy to the wireless charging module.

[0012] In some embodiments of this application, the housing further includes a first housing, a second housing, and a third housing.

The third housing is detachably located on the side of the first housing away from the second housing, and the third housing and the first housing form a second receiving space. The side of the third housing away from the second receiving space has a mounting groove. The first end of the wireless charging module is rotatably disposed in the mounting groove, and the second end of the wireless charging module can rotate around the first end so that the second end extends out of the mounting groove.

[0034] The following is a detailed description of this application.

[0035] Charging cables or data cables serve as power supply or data transmission devices for small mobile electronic devices, and can be used in mobile terminal devices including smartphones, laptops, and tablets. Charging cables connect mobile terminals to a power source to transfer electrical energy; data cables connect two mobile terminals or a mobile terminal to a host device to transmit data or information. The environments in which charging cables or data cables are used typically include homes, offices, and other locations with long-term power supply; in particular, users have increasing needs for adjustable charging cable or data cable lengths.

[0036] In related technologies, charging cables or data cables have limited functionality, and the length of the transmission line is not flexible enough to meet diverse usage needs.

[0037] Reference Figure 1 , Figure 2 and Figure 3 This application provides a multi-functional retractable cable, which includes a housing 1, a transmission line assembly 2, a rotating component 3, and a charging module 5. The housing 1 has an accommodating space. The transmission line assembly 2 includes at least a first transmission line 21 and a second transmission line 22, which are electrically connected. Both the first transmission line 21 and the second transmission line 22 include an interface end 23 for connecting to an electrical device or a power supply device. The rotating component 3 is disposed within the accommodating space and includes at least a first wheel core 31 and a second wheel core 32. The first wheel core 31 rotates relative to the housing 1 to wind up or unwind the first transmission line 21. The second wheel core 32 rotates relative to the housing 1 to wind up or unwind the second transmission line 22, and the first wheel core 31 and the second wheel core 32 rotate relative to the housing 1 respectively. The charging module 5 is disposed within the accommodating space and is capable of storing electrical energy and / or charging electrical devices. The charging module 5 is electrically connected to the transmission line assembly 2.

[0038] In this embodiment, the accommodating space is used to accommodate structures such as the first wheel core 31, the second wheel core 32, the first transmission line 21, and the second transmission line 22, and the housing 1 can protect the structures or components housed in the first accommodating space.

[0039] In this embodiment of the application, the transmission line group 2 may further include a third transmission line, a fourth transmission line, etc. For example, the transmission line group 2 may include a first transmission line 21, a second transmission line 22, a third transmission line, and a fourth transmission line, wherein the first transmission line 21 is used to connect to an input device, and the second transmission line 22, the third transmission line, and the fourth transmission line are all used to connect to an input device.

[0040] It should be explained that "power supply equipment" refers to devices that can input data or electrical energy into the multi-functional retractable cable, such as batteries and computer hosts; "electrical consumption equipment" refers to devices that can input electrical energy or data through the multi-functional retractable cable, such as mobile phones and laptops. Interface 23 is used to connect external devices (such as mobile phones, tablets, headphones, etc.) to achieve charging or data transmission functions. Interface 23 can be a Type-C plug, suitable for data transmission and charging, or it can be a Lightning plug, etc.

[0041] In this embodiment, the first transmission line 21 is wound around the first wheel core 31. When the first wheel core 31 rotates relative to the housing 1, the first transmission line 21 can be wound or unwound. The rotation of the first wheel core 31 allows the first transmission line 21 to be wound onto the first wheel core 31 for storage. The second transmission line 22 is wound around the second wheel core 32. When the second wheel core 32 rotates relative to the housing 1, the second transmission line 22 can be wound or unwound. The rotation of the second wheel core 32 allows the second transmission line 22 to be wound onto the second wheel core 32 for storage.

[0042] It should be explained that when the first transmission line 21 is wound around the first wheel core 31, the first transmission line 21 is housed within the first receiving space; when the first transmission line 21 is released relative to the first wheel core 31, at least a portion of the first transmission line 21 is located outside the first receiving space. Similarly, when the second transmission line 22 is wound around the second wheel core 32, the second transmission line 22 is housed within the second receiving space; when the second transmission line 22 is released relative to the second wheel core 32, at least a portion of the second transmission line 22 is located outside the second receiving space.

[0043] In this embodiment, the first transmission line 21 and the second transmission line 22 are electrically connected. The end of the first transmission line 21 closest to the axis of the first wheel core 31 is the first connection end, and the end of the second transmission line 22 closest to the second wheel core 32 is the second connection end. The first connection end and the second connection end are electrically connected. This application does not limit the method of electrical connection. The first connection end and the second connection end can be directly connected by laser welding or resistance welding.

[0044] In this embodiment, the first wheel core 31 and the second wheel core 32 rotate relative to the housing 1, so that the first transmission line 21 and the second transmission line 22 can be wound up or unwound respectively, and the length of the first transmission line 21 and the second transmission line 22 extending out of the first accommodating space can be independently controlled, thereby reducing the mutual interference between the first transmission line 21 and the second transmission line 22.

[0045] In this embodiment of the application, the first core 31 and the second core can rotate relative to the housing 1 respectively, and the winding or unwinding length of the first transmission line 21 and the second transmission line 22 can be controlled respectively. For example, the portion of the first transmission line 21 extending out of the first receiving space can reach 1.5 meters, and the portion of the second transmission line 22 extending out of the first receiving space can reach 0.8 meters.

[0046] In this embodiment, the charging module 5 is capable of storing electrical energy, and the charging module 5 is electrically connected to the transmission line group 2. Therefore, the charging module 5 can supply electrical energy to the transmission line group 2. For example, if a power supply device can be connected to one of the transmission line groups 2, the electrical energy of the power supply device can be input to the charging module 5 through the transmission line, so that the charging module 5 stores electrical energy. The charging module 5 can store only electrical energy, or it can supply power to the device while storing electrical energy. When the transmission line group 2 is connected to the device, the charging module 5 can transmit the stored electrical energy to the device through the transmission line group 2.

[0047] The multi-functional retractable cable provided in this application reduces the problem of tangling between the first transmission line 21 and the second transmission line 22 because the first transmission line 21 and the second transmission line 22 are wound around different wheel cores. Since the first wheel core 31 and the second wheel core 32 can rotate relative to the housing 1, and the rotation of the first wheel core 31 corresponds to the winding or unwinding of the first transmission line 21, and the rotation of the second wheel core 32 corresponds to the winding or unwinding of the second transmission line 22, independent winding and unwinding of the first transmission line 21 and the second transmission line 22 can be achieved. This allows for independent adjustment of the first transmission line 21 and the second transmission line 22 without interference. Users can adjust the first transmission line 21 and / or the second transmission line 22 individually according to their needs, thereby meeting diverse user requirements and improving the product's versatility. Because the charging module 5 can store electrical energy and charge electrical devices, and the transmission line group 2 is also electrically connected to the charging module 5, the multi-functional retractable cable provided in this application can independently charge electrical devices even when there is no power supply, thus improving convenience. Therefore, the multi-functional retractable cable provided in this application can independently charge electrical equipment without a power source, and can also independently adjust the winding and unwinding of the first transmission line 21 and the second transmission line 22, thus improving the convenience and flexibility of the multi-functional retractable cable.

[0048] Reference Figure 3 In one possible embodiment of this application, the multi-functional retractable cable further includes a circuit board assembly 8, which includes a first circuit board 81 and a second circuit board 82. The first circuit board 81 is electrically connected to the first transmission line 21 and the second transmission line 22, respectively, and the second circuit board 82 is electrically connected to the charging module 5 and the first circuit board 81, respectively.

[0049] In this embodiment, the first circuit board 81 is used to electrically connect the first transmission line 21 and the second transmission line 22. For example, the first connection end and the second connection end can also be connected via the circuit board assembly 8, as shown in reference... Figure 2 and Figure 3 A first terminal plate 83 is disposed on the side of the first wheel core 31 near the second wheel core 32, and is connected to a first connecting end. A second terminal plate 84 is disposed on both sides of the second wheel core 32 near the first wheel core 31, and is connected to a second connecting end. Both the first terminal plate 83 and the second terminal plate 84 are each soldered with at least two sets of 5-pin connectors. A first circuit board 81 is disposed between the first terminal plate 83 and the second terminal plate 84. Five copper rings are disposed in the middle of the first circuit board 81, and the first terminal plate 83 and the second terminal plate 84 are connected to the five copper rings of the first circuit board 81 via 5-pin connectors, thereby allowing the first terminal plate 83 and the second terminal plate 84 to rotate relative to the first circuit board 81 and be electrically connected. It should be noted that the first circuit board 81 is annular to allow the first terminal plate 83 and the second terminal plate 84 to rotate relative to the first circuit board 81.

[0050] In this embodiment, the second circuit board 82 is used to electrically connect the first circuit board 81 and the charging module 5. That is, the second circuit board 82 electrically connects the transmission line group 2 and the charging module 5. Therefore, the transmission line group 2 can transmit electrical energy to the charging module 5 through the second circuit board 82, and the electrical energy stored in the charging module 5 can also be transmitted to the first circuit board 81 through the second circuit board 82, and then transmitted by the first circuit board 81 to the first transmission line 21 and the second transmission line 22.

[0051] Reference Figure 3 and Figure 6 In one possible embodiment of this application, the second circuit board 82 includes a first connection portion and a second connection portion disposed opposite to each other, the charging module 5 is electrically connected to the first connection portion, and the first circuit board 81 is electrically connected to the second connection portion.

[0052] In this embodiment, the first connecting part and the second connecting part are arranged opposite to each other, that is, the first connecting part and the second connecting part are located on both sides of the second circuit board 82 respectively. The charging module 5 and the first connecting part are connected by a wire group. A wire group is also connected between the first circuit board 81 and the second connecting part. Therefore, because the wire group connected to the first connecting end and the wire group connected to the second connecting part are spaced far apart and are located on different sides of the second circuit board 82 respectively, they will not interfere with each other, thus improving the safety and rationality of the circuit layout.

[0053] Reference Figure 3 and Figure 6In one possible embodiment of this application, the housing 1 includes a partition 19 that divides the accommodating space into a first accommodating space and a second accommodating space; the transmission line group 2, the rotating assembly 3 and the first circuit board 81 are disposed in the first accommodating space, and the charging module 5 and the second circuit board 82 are disposed in the second accommodating space.

[0054] In this embodiment, the partition 19 is used to divide the accommodating space into a first accommodating space and a second accommodating space. The size of the first and second accommodating spaces is not limited in this application. The charging module 5 and the second circuit board 82 are disposed within the second accommodating space.

[0055] In this embodiment, the first accommodating space is used to accommodate the rotating component 3 and the transmission line group 2. For example, see [reference needed]. Figure 4 and Figure 5 The first wheel core 31 and the second wheel core 32 rotate relative to the housing 1 along the same rotation axis C, and the first accommodating space and the second accommodating space are stacked along the direction of the rotation axis C. The second accommodating space and the first accommodating space can be stacked along the direction of the rotation axis C, which can optimize the internal space of the housing 1 and reduce the increase in the lateral dimension of the housing 1.

[0056] The multi-functional telescopic cable provided in this application isolates the rotating component 3 and the charging module 5 spatially through the first and second accommodating spaces, ensuring that the rotation of the first wheel core 31 and the second wheel core 32 is not affected by the charging module 5. It also reduces the impact of the first transmission line 21 and the second transmission line 22 on the performance of the charging module 5 during extension and retraction.

[0057] Reference Figure 3 , Figure 5 and Figure 6 In one possible embodiment of this application, the partition 19 has a through hole 191 that connects the first accommodating space and the second accommodating space; the multi-functional telescopic cable also includes a wire harness 4, one end of which is electrically connected to the second circuit board 82, and the other end of which passes through the through hole 191 and is electrically connected to the first circuit board 81.

[0058] In this embodiment, the charging module 5 is electrically connected to the second circuit board 82. The second circuit board 82 can be fixed in the second accommodating space by screws or clips. The wire harness passes through the through hole 191 reserved on the partition 19 to electrically connect the second circuit board 82 and the first circuit board 81.

[0059] It should be added that the shape and size of the through hole 191 are not limited in this application and can be adjusted according to the size of the wiring harness used to connect the second circuit board 82 and the first circuit board 81.

[0060] The multi-functional telescopic cable provided in this application embodiment has a through hole on the partition 19, which can be used to arrange the wire harness 4 connecting the first circuit board 81 and the second circuit board 82. This allows for convenient electrical connection of the first circuit board 81 and the second circuit board 82, and also saves on the use of the wire harness 4.

[0061] Reference Figure 3 , Figure 5 and Figure 6 In one possible embodiment of this application, the charging module 5 includes a battery assembly 51 and a wireless charging module 52, both of which are electrically connected to a second circuit board 82. The battery assembly 51 can be used to store electrical energy input from the first transmission line 21 and to transmit electrical energy to the second transmission line 22. The wireless charging module 52 is electrically connected to the battery assembly 51 through the second circuit board 82, and the battery assembly 51 can provide electrical energy to the wireless charging module 52.

[0062] In this embodiment, both the wireless charging module 52 and the battery assembly 51 are electrically connected to the second circuit board 82. The capacity of the battery assembly 51 can be 2000 mAh.

[0063] For example, when the first transmission line 21 is used to connect to a power supply device and the second transmission line 22 is used to connect to a power user device, the electrical energy input through the first transmission line 21 can be stored in the battery assembly 51. When the first transmission line 21 is not connected to a power source, the battery assembly 51 can provide electrical energy to power the mobile device connected to the second transmission line 22. Simultaneously, the battery assembly 51 can support simultaneous charging and discharging. When the first transmission line 21 is connected to an external power source, it can support a maximum of 100 watts (W), allowing the battery assembly 51 to simultaneously charge itself and power external devices.

[0064] In this embodiment, the wireless charging module 52 is used to provide power to output devices (such as mobile phones, headphones, etc.) without using the transmission line group 2. The wireless charging module 52 can be disposed on one side surface of the housing 1 for easy inductive charging of mobile devices. When the first transmission line 21 is connected to a power source, the battery assembly 51 can be charged first, while power is supplied to external devices through the wireless charging module 52.

[0065] In this embodiment, the battery assembly 51 can simultaneously power the wireless charging module 52 and the second transmission line 22. The power supply method is that the wireless charging module 52 prioritizes outputting electrical energy (the maximum output power can be 15 watts). When the wireless charging module 52 is not enabled, it can automatically switch to wired output mode, that is, use the second transmission line 22 to output electrical energy (output voltage 5 volts / current 2 amps).

[0066] The multi-functional retractable cable provided in this application embodiment includes a wireless charging module 52 and a battery assembly 51. The wireless charging module 52 can charge electronic devices with wireless charging function (such as using a mobile phone while charging). After storing electrical energy, the battery assembly 51 can provide power to power supply equipment in emergency situations in mobile scenarios.

[0067] Reference Figure 3 and Figure 4 In one possible embodiment of this application, the housing 1 includes a first support shaft 11 and a second support shaft 12. A first wheel core 31 is sleeved on the first support shaft 11 and rotatably connected to the first support shaft 11. A second wheel core 32 is sleeved on the second support shaft 12 and rotatably connected to the second support shaft 12. The first support shaft 11 and the second support shaft 12 are separately disposed.

[0068] In this embodiment, the first support shaft 11 provides support and a rotation axis for the first wheel core 31, and the second support shaft 12 provides support and a rotation axis for the second wheel core 32. The axial relationship between the first support shaft 11 and the second support shaft 12 can be adjusted as needed. The first support shaft 11 and the second support shaft 12 can be parallel, and their axes can be coaxial or non-coaxial.

[0069] In one embodiment of this application, reference is made to Figure 4 and Figure 5 The first support shaft 11 and the second support shaft 12 are coaxially arranged, such as the rotation axis C. With this structure, the first wheel core 31 and the second wheel core 32 are stacked inside the housing 1 along the rotation axis C, which can make the structure between the first wheel core 31 and the second wheel core 32 compact and reduce the size of the housing 1.

[0070] In this embodiment of the application, the first wheel core 31 is sleeved on the first support shaft 11 and can rotate around the first support shaft 11, and the second wheel core 32 is sleeved on the second support shaft 12 and can rotate around the second support shaft 12.

[0071] In this embodiment, the multi-functional telescopic cable may further include a gear damping assembly 6 and a spring reset assembly 7, so that the first transmission line 21 and the second transmission line 22 can be locked at any length after release, reducing springback and improving stability.

[0072] Reference Figure 2 and Figure 3 In this embodiment, the first wheel core 31 is provided with a gear damping assembly 6 and a spring reset assembly 7, and the second wheel core 32 is also provided with a gear damping assembly 6 and a spring reset assembly 7. The spring reset assembly 7 provides the power for winding, enabling the transmission line to be automatically retracted and wound onto the corresponding wheel core.

[0073] Taking the first core 31 and the first support shaft 11 as an example, the inner end of the spring reset assembly 7 can be anchored on the first support shaft 11, and the outer end of the spring reset assembly 7 is connected to the inner wall of the first core 31. When the transmission line is released, the first core 31 rotates to make the spring reset assembly 7 wind up and store energy. The torque range of the spring reset assembly 7 is adjusted according to the size of the transmission line. When the energy stored in the spring reset assembly 7 is released, it can drive the first core 31 to rotate, thereby winding up the first transmission line 21.

[0074] In this embodiment of the application, the gear damping assembly 6 includes a plum blossom wheel 61, a rocker arm 62, and a spring plate 63. The plum blossom wheel 61 can be fixed inside the first wheel core 31. The plum blossom wheel 61 rotates synchronously with the first wheel core 31. The rocker arm 62 and the spring plate 63 are fixed on the bracket of the housing 1 or the first support shaft 11.

[0075] The multi-functional telescopic cable provided in this application embodiment allows for independent rotation of the two wheel cores because the first wheel core 31 and the second wheel core 32 are independently sleeved on the corresponding first support shaft 11 and second support shaft 12, forming a rotatable connection. Since the first support shaft 11 and the second support shaft 12 are separate structures, mechanical interference between the two shafts is reduced, ensuring that the rotational movements of the two wheel cores do not affect each other.

[0076] Reference Figure 3 and Figure 4 In one possible embodiment of this application, the housing 1 includes a first cable port 13 and a second cable port 14. A first transmission line 21 passes through the first cable port 13, and a second transmission line 22 passes through the second cable port 14. The first cable port 13 and the second cable port 14 are respectively located on opposite sides of the housing 1.

[0077] In this embodiment of the application, the first cable port 13 and the second cable port 14 are openings on the housing 1. The first transmission line 21 can pass through the first cable port 13, and the second transmission line 22 can pass through the second cable port 14, so that the first transmission line 21 and the second transmission line 22 extend out of the first receiving space.

[0078] In this embodiment, the dimensions of the first cable port 13 and the second cable port 14 can be adjusted according to the dimensions of the first transmission line 21 and the second transmission line 22.

[0079] In this embodiment, the side plates of the housing 1 on both sides where the first wire hole and the second wire hole are provided can be detachable structures, as shown in the reference. Figure 3 and Figure 4 The first side plate 1A is provided with a first wire passage 13, and the second side plate 1B is provided with a second wire passage 14. This structure facilitates disassembly and maintenance.

[0080] In this embodiment, the first wire passage 13 and the second wire passage 14 are respectively disposed on opposite sides of the housing 1. According to the rotation direction of the first wheel core 31 and the second wheel core 32, the first wire passage 13 and the second wire passage 14 are disposed on the side of the housing 1 in the rotation direction, so as to adapt to the rotation of the first wheel core 31 and the second wheel core 32, and facilitate the first transmission line 21 and the second transmission line 22 to pass through the first wire passage 13 and the second wire passage 14.

[0081] The multi-functional telescopic cable provided in this embodiment, because the first cable passage 13 and the second cable passage 14 are respectively located on opposite sides of the housing 1, can provide two different release paths for the first transmission line 21 and the second transmission line 22, reducing the entanglement of the first transmission line 21 and the second transmission line 22 during the extension and retraction process. Furthermore, the force exerted on the housing 1 by the first transmission line 21 and the second transmission line 22 during the extension and retraction process is symmetrically distributed on opposite sides of the housing 1, which can balance the force on the housing 1 and reduce unilateral wear of the housing 1.

[0082] Reference Figure 3 and Figure 4 In one possible embodiment of this application, the housing 1 further includes a first housing 151, a second housing 161, and a third housing 171. The second housing 161 is detachably connected to the first housing 151 and forms a first accommodating space. The third housing 171 is detachably attached to the side of the first housing 151 away from the second housing 161, and the third housing 171 and the first housing 151 form a second accommodating space. The side of the third housing 171 away from the second accommodating space has a mounting groove 171. The first end 521 of the wireless charging module 52 is rotatably disposed in the mounting groove 171, and the second end 522 of the wireless charging module 52 can rotate around the first end 521 so that the second end 522 extends out of the mounting groove 171.

[0083] In this embodiment, the housing 1 is a split structure, including a first housing 151, a second housing 161, and a third housing 171. The third housing 171 and the second housing 161 are detachably connected to both sides of the first housing 151, forming a first accommodating space between the first housing 151 and the second housing 161, and a second accommodating space between the first housing 151 and the third housing 171. That is, the first housing 151 separates the first accommodating space and the second accommodating space.

[0084] In this embodiment of the application, the detachable connection between the first housing 151, the second housing 161 and the third housing 171 can be achieved by means of snaps or threads.

[0085] The multi-functional telescopic cable provided in this application embodiment has a first housing 151, a second housing 161 and a third housing 171 that are detachably connected, which facilitates the disassembly, assembly and maintenance of the various built-in components such as the rotating component 3, the battery component 51, and the wireless charging module 52 inside the housing 1. The first housing 151 separates the first accommodating space and the second accommodating space, which can reduce the mutual interference between the various components placed in the first accommodating space and the second accommodating space.

[0086] In this embodiment, the mounting groove 171 is used to accommodate the wireless charging module 52. Therefore, the shape of the mounting groove 171 can be adjusted according to the shape of the wireless charging module 52. The first end 521 of the wireless charging module 52 can be rotatably connected to the mounting groove 171 through a rotating shaft, hinge or other mechanism, forming a fulcrum for the rotation of the wireless charging module 52.

[0087] In this embodiment, the second end 522 rotates outward and extends out of the mounting groove 171, exposing the charging surface to the outside of the housing 1. The second end 522 can rotate inward and retract, so that the wireless charging module 52 is hidden in the mounting groove 171, thereby protecting the wireless charging module 52 and maintaining the flatness of the housing 1.

[0088] In this embodiment, when the second end 522 of the wireless charging module 52 is housed in the mounting slot 171, the mobile device can be placed on one side of the housing 1 where the wireless charging module 52 is located for charging. When the second end 522 of the wireless charging module 52 is rotated to extend out of the mounting slot 171, an angle is generated between the wireless charging module 52 and the surface of the housing 1. Taking a mobile phone as an example, the mobile phone can be placed at the angle between the wireless charging module 52 and the housing 1. The wireless charging module 52 can be used as a stand so that the mobile phone can be charged by the wireless charging module 52 while the user is observing or using the mobile phone.

[0089] Reference Figure 3 , Figure 4 and Figure 6 In one possible embodiment of this application, the third housing 17 is formed with a boss 172, and a mounting groove 171 is disposed on the boss 172. The second circuit board 82 is provided with an avoidance notch corresponding to the boss 172, and the outline of the avoidance notch is adapted to the outline of the boss 172.

[0090] In this embodiment, the boss 172 is a protruding platform structure on the third housing 17, used to support or position the mounting groove 171. The clearance notch is an opening on the second circuit board 82 that matches the contour of the boss 172, used to avoid physical interference with the boss 172. Through shape adaptation (such as consistent size and curvature), the second circuit board 82 and the boss 172 can fit together without conflict.

[0091] The multi-functional telescopic cable provided in this embodiment allows the second circuit board 82 and the boss 172 to be misaligned within the second accommodating space by avoiding the notch, saving internal space of the housing 1 and facilitating the thinning and lightening of the housing 1. Furthermore, by providing a local avoidance notch on the second circuit board 82, the second circuit board 82 balances functional layout and structural constraints, allowing for more flexible adaptation to the internal space of the housing 1.

[0092] Reference Figure 3 and Figure 4 In one possible embodiment of this application, at least two receiving grooves 18 are provided on the outer side of the housing 1, the interface end 23 is accommodated in the corresponding receiving groove 18, and the receiving groove 18 is provided with an arc-shaped guide surface 181, which is used to guide the movement of the corresponding interface end 23.

[0093] In this embodiment, the receiving groove 18 is a recessed structure provided on the surface of the housing 1, used to receive the interface end 23 and improve the flatness of the housing 1 surface. For example, see... Figure 3 and Figure 4 There are two receiving slots 18, which are respectively set at the positions of the first outlet and the second outlet, so as to accommodate the interface end 23 of the first transmission line 21 and the second transmission line 22.

[0094] In this embodiment, the arc-shaped guide surface 181 is a curved surface structure within the receiving groove 18. For example, see reference... Figure 3 and Figure 4 The arc-shaped guide surface 181 is set on the side of the receiving groove 18 away from the corresponding outlet. For example, the arc-shaped guide surface 181 of the receiving groove 18 corresponding to the first outlet is set away from the first outlet. In this way, the arc-shaped guide surface 181 can guide and direct the first transmission line 21 on the release path.

[0095] The multi-functional telescopic cable provided in this embodiment has a receiving groove 18. When the interface end 23 is not in use, it can be accommodated in the receiving groove 18, reducing the clutter on the interface end 23 and reducing wear caused by the interface end 23 being exposed to the external environment. Since the receiving groove 18 is also provided with an arc-shaped guide surface 181, it can assist the interface end 23 in entering and exiting the receiving groove 18.

[0096] In one possible embodiment of this application, each interface end 23 is provided with a first magnetic element, and the inner surface of the housing 1 corresponding to each receiving groove 18 is provided with a second magnetic element, and the first magnetic element and the second magnetic element are magnetically attracted to each other.

[0097] In this embodiment, the first magnetic component and the second magnetic component attract each other. When the interface end 23 is near the receiving groove 18, the interface end 23 can be attracted into the receiving groove 18. In this way, it is not necessary to accurately position the interface end 23 and the receiving groove 18 during use, which reduces the difficulty of storage.

[0098] The multi-functional telescopic cable provided in this application embodiment has an interface end 23 that is kept relatively fixed to the receiving groove 18 by magnetic force when stored, which reduces the phenomenon of the interface end 23 becoming loose due to vibration, movement, etc. Even if it is subjected to slight impact, the interface end 23 can still maintain an adsorption state with the receiving groove 18.

[0099] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.

In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
