Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0023] Please see Figures 1 to 2 This application provides a multi-functional charging cable 10, which includes a cable body 110, a first connector 130, a second connector 140, a circuit board 210, and a wireless charging coil 233.

[0024] The first connector 130 and the second connector 140 can both be used to plug into electrical devices (such as mobile phones, tablets, laptops, or other electrical devices) or charging heads. The first connector 130 and the second connector 140 can be the same or different.

[0025] As an example, both the first connector 130 and the second connector 140 can be Type-C connectors or other connectors.

[0026] The line body 110 includes a positive power line 111 (i.e., VBUS line), a negative power line 113 (i.e., GND line), and a first signal line 121 (CC1 line). The positive power line 111, the negative power line 113, and the first signal line 121 are all covered with a first insulating layer to insulate each other.

[0027] Each of the positive power line 111, the negative power line 113, and the first signal line 121 includes a first end and a second end opposite to each other, and an electrical connection portion 119 located between the first end and the second end.

[0028] As an example, each of the wire cores (i.e., the positive power line 111, the negative power line 113, and the first signal line 121) includes a conductive wire and a first insulating layer covering the conductive wire. The electrical connection portion 119 can be formed by partially opening in the first insulating layer to expose the conductive wire inside the wire core, and the first end and the second end can refer to the conductive wires exposed at both ends of the wire core.

[0029] The first connector 130 is electrically connected to the first end of the positive power line 111, the negative power line 113, and the first signal line 121. The second connector 140 is electrically connected to the second end of the positive power line 111, the negative power line 113, and the first signal line 121. Thus, the first signal line 121 can transmit a connector identification signal indicating that the first connector 130 and the second connector 140 have a device connected. The first connector 130 and the second connector 140 can achieve wired charging through the positive power line 111 and the negative power line 113.

[0030] Circuit board 210 is electrically connected to the electrical connection portion 119 of positive power line 111, negative power line 113 and first signal line 121. Wireless charging coil 233 is electrically connected to circuit board 210. Thus, wireless charging coil 233 and each connector (i.e., first connector 130 and second connector 140) can share positive power line 111, negative power line 113 and first signal line 121. First signal line 121 can transmit wireless charging identification signal when a device is connected to wireless charging coil 233. First connector 130 or second connector 140 can supply power to wireless charging coil 233 through positive power line 111 and negative power line 113. After being energized, wireless charging coil 233 generates an alternating magnetic field to wirelessly charge the device. Thus, the multi-functional charging cable 10 provided in this application embodiment can realize wired charging and wireless charging at the same time, expanding the function of multi-functional charging cable 10 and better meeting the user's needs.

[0031] Furthermore, since the wireless charging coil 233 and each connector share the positive power line 111, the negative power line 113 and the first signal line 121, there is no need to add an additional power supply structure to power the wireless charging coil 233, which helps to simplify the overall structure of the multi-functional charging cable 10 and reduce the manufacturing cost of the multi-functional charging cable 10.

[0032] Furthermore, since both the first connector 130 and the second connector 140 are connected to the same solder point on the circuit board 210 through the electrical connection portion 119 of the first signal line 121, there is no need to distinguish between the input and output of the first connector 130 and the second connector 140. Either the first connector 130 or the second connector 140 can be connected to a power supply device, while the other and the wireless charging coil 233 can both be connected to a power receiving device, which helps to realize blind insertion of each connector and provides a better user experience.

[0033] For ease of description, the electrical connection portion 119 of the positive power line 111 is defined as the first electrical connection portion 1191, the electrical connection portion 119 of the negative power line 113 is defined as the second electrical connection portion 1193, and the electrical connection portion 119 of the first signal line 121 is defined as the third electrical connection portion 1195.

[0034] As an example, the circuit board 210 may have a first positive solder joint, a first negative solder joint, a first signal solder joint, a first connection solder joint, and a second connection solder joint spaced apart from each other. Specifically, a first electrical connection portion 1191 can be soldered to the first positive solder joint, a second electrical connection portion 1193 can be soldered to the first negative solder joint, and a third electrical connection portion 1195 can be soldered to the first signal solder joint. The two ends of the wireless charging coil 233 can be soldered to the first connection solder joint and the second connection solder joint, respectively. One of the first and second connection solder joints can be electrically connected to the first positive solder joint via a line on the circuit board 210, and the other can be electrically connected to the first negative solder joint via a line on the circuit board 210.

[0035] Understandably, the multi-functional charging cable 10 in this embodiment can adopt the PD (Power Delivery) charging protocol. Each first end can be electrically connected to the control board inside the first connector 130, and each second end can be electrically connected to the control board inside the second connector 140. Both the control board and the circuit board 210 can be PCBA (Printed Circuit Board Assembly).

[0036] As an example, taking the first end and the first connector 130 as examples, the first connector 130 may include a plug and a control board. Each first end and plug can be welded to the control board, and then an inner shell is injection molded onto the control board. The first end and plug are partially fixed to the inner shell, thereby fixing the first end, the control board, and the plug. An outer shell can also be fitted over the inner shell. For details, please refer to the prior art, which will not be described in detail here. The structure of the second connector 140 is roughly the same as that of the first connector 130. The connection method of each second end and the second connector 140 can refer to the connection method of the first end and the first connector 130, which will not be described in detail here.

[0037] In some embodiments, the line body 110 may also include a second signal line 150 (CC2 line).

[0038] The second signal line 150 may also be covered with a first insulating layer. The structure of the second signal line 150 can refer to the positive power line 111 in the above embodiment. The difference is that the second signal line 150 does not need to be provided with an electrical connection part 119, which will not be described in detail here.

[0039] One end of the second signal line 150 is electrically connected to the first connector 130, and the other end is electrically connected to the second connector 140 to supply power to the control chip (IC) in each connector. For details, please refer to the existing technology, which will not be elaborated here.

[0040] When the cable body 110 includes only the first signal line 121, the multi-functional charging cable 10 can achieve 60W charging; when the cable body 110 includes both the first signal line 121 and the second signal line 150, the multi-functional charging cable 10 can achieve 100W charging.

[0041] In some embodiments, the multi-functional charging cable 10 may also adopt the QC (Quick Charge) charging protocol, and the cable body 110 may further include a positive data line 115 (D+ line) and a negative data line 117 (D- line).

[0042] Both the positive data line 115 and the negative data line 117 can be covered with a first insulating layer. The structure of the positive data line 115 and the negative data line 117 can refer to the positive power line 111 in the above embodiment. The difference is that the positive data line 115 and the negative data line 117 do not need to be provided with an electrical connection part 119, which will not be described in detail here.

[0043] One end of the positive data cable 115 and the negative data cable 117 are electrically connected to the first connector 130, and the other end is electrically connected to the second connector 140, thereby enabling wired data transmission between the first connector 130 and the second connector 140, further expanding the functionality of the multi-functional charging cable 10 and better meeting the user's needs.

[0044] In some embodiments, the positive power line 111, negative power line 113, first signal line 121, second signal line 150, positive data line 115, and negative data line 117 may have different colors of their outer first insulating layers depending on their different functions, so as to facilitate differentiation.

[0045] As an example, the first insulation layer of the positive power line 111 can be red, and the first insulation layer of the negative power line 113 can be black. The first insulation layer of the positive data line 115 can be green, and the first insulation layer of the negative data line 117 can be white. The first insulation layer of the first signal line 121 can be yellow, and the first insulation layer of the second signal line 150 can be gray.

[0046] Please see Figure 1 and Figure 3 In some embodiments, the multi-functional charging cable 10 may also include an adapter cable 400.

[0047] Each electrical connection 119 corresponds to a converter cable 400, which is electrically connected between the electrical connection 119 and the circuit board 210, thereby allowing for a more flexible arrangement of the relative positions of the electrical connection 119 and the circuit board 210.

[0048] As an example, the adapter cable 400 may include conductive wires and an insulating layer covering the conductive wires. At both ends of the adapter cable 400, the conductive wires may be exposed outside the insulating layer to electrically connect to the electrical connection portion 119 and the circuit board 210, respectively. The electrical connection may be achieved by soldering, conductive adhesive bonding, twisted contact, or other methods. The multi-functional charging cable 10 may include three adapter cables 400, defined as a first adapter cable, a second adapter cable, and a third adapter cable. The first adapter cable may be electrically connected between the first electrical connection portion 1191 and the first positive solder joint, the second adapter cable may be electrically connected between the second electrical connection portion 1193 and the first negative solder joint, and the third adapter cable may be electrically connected between the third electrical connection portion 1195 and the first signal solder joint.

[0049] In some embodiments, the multi-functional charging cable 10 may further include a positioning seat 250, with each electrical connection portion 119 corresponding to one positioning seat 250. Specifically, the multi-functional charging cable 10 may further include three positioning seats 250, with the first electrical connection portion 1191, the second electrical connection portion 1193, and the third electrical connection portion 1195 each corresponding to one positioning seat 250.

[0050] The positioning base 250 can be connected to the circuit board 210 and is provided with a first slot 251. The electrical connection part 119 is engaged in the first slot 251. That is, the first electrical connection part 1191, the second electrical connection part 1193 and the third electrical connection part 1195 can be engaged in the first slot 251 of the positioning base 250 respectively, thereby fixing the position of the positive power line 111, the negative power line 113 and the first signal line 121. This helps to prevent the positive power line 111, the negative power line 113 and the first signal line 121 from shaking and short-circuiting each other or short-circuiting with electrical components on the circuit board 210.

[0051] As an example, the positioning base 250 can be inserted into the circuit board 210, and the positioning base 250 and the circuit board 210 can be fixed together by adhesive. The adhesive can be an insulating adhesive to reduce the possibility of short circuits; or the positioning base 250 can be directly bonded to the circuit board 210 by insulating adhesive. The first slot 251 can penetrate the positioning base 250 and can be provided with an opening. The opening can be provided on the outer wall of the positioning base 250, and the electrical connection part 119 can be inserted into the first slot 251 through the opening. The size of the first slot 251 can be adapted to the size of the electrical connection part 119 so that the electrical connection part 119 can be fixed in the first slot 251.

[0052] In some embodiments, the positioning seat 250 may include an insulating portion and a conductive portion.

[0053] The insulating part can be connected to the circuit board 210, and the conductive part can be connected to the insulating part and spaced apart from the circuit board 210, thereby preventing the positioning seat 250 from short-circuiting with other electrical components on the circuit board 210.

[0054] As an example, the conductive part can be connected to the side of the insulating part facing away from the circuit board 210. The insulating part can be made of plastic or other materials. The conductive part can be made of conductive metal or other conductive materials, and the conductive part and the insulating part can be bonded, snapped together, or injection molded into a single structure.

[0055] The conductive part may be provided with a first slot 251, and the adapter cable 400 may be electrically connected to the electrical connection part 119 and / or the conductive part, thereby providing a larger electrical connection area for the adapter cable 400. The adapter cable 400 may be arbitrarily electrically connected to the electrical connection part 119 and / or the conductive part.

[0056] As an example, the electrical connection part 119 can be directly snapped into the first slot 251, and the electrical connection part 119 can contact the inner wall of the first slot 251 to realize the electrical connection between the electrical connection part 119 and the conductive part.

[0057] As another example, the electrical connection part 119 can be snapped into the first slot 251 and welded to fix it, so as to realize the electrical connection between the electrical connection part 119 and the conductive part, which helps the electrical connection part 119 to be more stably fixed in the first slot 251.

[0058] In the above example, the adapter cable 400 can be plugged into the first card slot 251 or located outside the first card slot 251.

[0059] In some embodiments, the conductive part may also be provided with a second slot, and the adapter cable 400 can be snapped into the second slot and electrically connected to the conductive part. Thus, the second slot can provide a more definite installation position for the adapter cable 400, which helps to improve production efficiency. The conductive part can serve as an intermediate conductive structure between the adapter cable 400 and the electrical connection part 119 to realize the electrical connection between the adapter cable 400 and the electrical connection part 119.

[0060] As an example, the conductive wire at one end of the adapter cable 400 can be inserted into the second slot, and the adapter cable 400 can be connected to the inner wall of the second slot to achieve electrical connection between the adapter cable 400 and the conductive part.

[0061] As another example, the conductive wire at one end of the adapter cable 400 can be inserted into the second slot and soldered to fix it, so as to realize the electrical connection between the adapter cable 400 and the conductive part, which helps to fix the conductive wire at one end of the adapter cable 400 more stably in the second slot.

[0062] Please see Figure 1 and Figure 4 In some embodiments, the multi-functional charging cable 10 may also include a riveting member 500 and a second insulating layer.

[0063] Each adapter cable 400 can be riveted to the corresponding electrical connection part 119 (e.g., using a riveting piece 500) via a riveting piece 500. Figure 3 As shown), the adapter cable 400 and the electrical connection part 119 are electrically connected.

[0064] As an example, the riveting component 500 can be a conductive sleeve, which can be fitted over the electrical connection portion 119. One end of the adapter cable 400 can be inserted into the conductive sleeve and contact or be twisted and fixed with the electrical connection portion 119. The conductive sleeve is then deformed by clamps or other equipment to ensure tight contact between the electrical connection portion 119 and one end of the adapter cable 400, thus achieving the riveting connection. This helps improve the connection strength between the adapter cable 400 and the electrical connection portion 119 and reduces the possibility of them detaching. Understandably, the conductive sleeve can also be a sleeve with an opening on the side, allowing it to be fitted over the electrical connection portion 119 through the opening.

[0065] The second insulating layer and the riveting part 500 can correspond one-to-one. Each second insulating layer can cover the riveting part 500 and the electrical connection part 119, thereby insulating and isolating the riveting part 500 and the electrical connection part 119, which helps to avoid the situation where the wire core shakes and comes into contact with other structures to conduct electricity.

[0066] The second insulation layer can be made of insulating tape, rubber tubing, or other insulating structures.

[0067] Please see Figure 1 and Figure 5 In some embodiments, the multi-functional charging cable 10 may further include a mounting base 231, a first conductive element 270, and a second conductive element 290.

[0068] The mounting base 231 can be mounted on the circuit board 210.

[0069] As an example, the mounting base 231 can be stacked on the circuit board 210. The mounting base 231 and the circuit board 210 can be glued together or their positions can be restricted by a housing, as described in subsequent embodiments. The mounting base 231 and each electrical connection 119 can be located on opposite sides of the circuit board 210, which helps to prevent the mounting base 231 from pressing against the electrical connection 119.

[0070] The first conductive element 270 and the second conductive element 290 can be electrically connected to the circuit board 210 to draw power from the circuit board 210.

[0071] As an example, one of the first conductive element 270 and the second conductive element 290 can be soldered to the first connection joint, and the other can be soldered to the second connection joint.

[0072] Mounting base 231 may be provided with a first mounting groove 2311 and a notch 2313. The notch 2313 is located on the outer wall of mounting base 231 and connects to the first mounting groove 2311. The first conductive element 270 and the second conductive element 290 are both at least partially protruding into the notch 2313. The wireless charging coil 233 is installed in the first mounting groove 2311. The wireless charging coil 233 is electrically connected to the first conductive element 270 and the second conductive element 290 respectively. Thus, the circuit board 210 can supply power to the wireless charging coil 233 through the first conductive element 270 and the second conductive element 290. After the wireless charging coil 233 is energized, it generates an alternating magnetic field to wirelessly charge the device. The specific principle of wireless charging can be referred to the existing technology, which will not be elaborated here.

[0073] In addition, since the first conductive element 270 and the second conductive element 290 are both at least partially protruding into the notch 2313, it helps to shorten the distance between the first conductive element 270, the second conductive element 290 and the wireless charging coil 233, making the overall structure more compact.

[0074] In some embodiments, the multi-functional charging cable 10 may also include a magnetic element 235, and the mounting base 231 may also be provided with a second mounting groove 2315.

[0075] The first mounting slot 2311 is arranged in a ring around the second mounting slot 2315. The magnetic component 235 is installed in the second mounting slot 2315, which helps to make better use of the space on the mounting base 231. The wireless charging coil 233 and the magnetic component 235 are more compact, and the magnetic component 235 can magnetically fix the electrical equipment, resulting in a better user experience.

[0076] In some embodiments, the multi-functional charging cable 10 may also include a housing 310.

[0077] The circuit board 210, mounting base 231, wireless charging coil 233, first conductive element 270 and second conductive element 290 can all be disposed within the housing 310. The housing 310 can restrict the position of the circuit board 210 and the mounting base to fix the circuit board 210 and the mounting base within the housing 310.

[0078] The cable 110 may be covered with a third insulating layer, and the cable 110 may be partially inserted into the housing 310. This allows the wireless charging structure to be directly installed at a local location on the cable 110. Visually, there are no redundant connection structures between the wireless charging structure and the cable 110, resulting in a more compact and aesthetically pleasing overall structure for the multi-functional charging cable 10. The wireless charging structure may include a circuit board 210, a mounting base 231, a wireless charging coil 233, a first conductive element 270, and a second conductive element 290, among other components.

[0079] The third insulating layer located inside the housing 310 can be opened to expose each electrical connection portion 119, thereby confining the electrical connection portion 119 within the housing 310 to facilitate electrical connection to the circuit board 210.

[0080] The housing 310 can be attached to the third insulating layer to fix the position of the housing 310 and help prevent the housing 310 from falling off the wire 110.

[0081] As an example, the two ends of the cable 110 can extend from opposite ends of the housing 310 to the outside of the housing 310. The multi-functional charging cable 10 may also include two clips, which can be respectively fitted onto the portions of the cable 110 at both ends of the housing 310. Each clip can be partially snapped into the housing 310 and partially located outside the housing 310. The inner wall of the clip located outside the housing 310 can be fitted with a third insulating layer.

[0082] Please see Figure 1 This application also provides another multi-functional charging cable 10, which differs from the multi-functional charging cable 10 in the above embodiment in that the cable body 110 has a different structure.

[0083] Specifically, in this embodiment, the multi-functional charging cable 10 includes a first power positive line (VBUS line), a first power negative line (GND line), a first wire signal line (CC1 line), a second power positive line (VBUS line), a second power negative line (GND line), a second wire signal line (CC1 line), a first connector 130, a second connector 140, a circuit board 210, and a wireless charging coil 233.

[0084] In this configuration, the first connector 130 is electrically connected to one end of the first power positive wire, the first power negative wire, and the first wire signal wire; the second connector 140 is electrically connected to one end of the second power positive wire, the second power negative wire, and the second wire signal wire; the other ends of the first power positive wire, the first power negative wire, the first wire signal wire, the second power positive wire, the second power negative wire, and the second wire signal wire are respectively electrically connected to the circuit board 210; and the wireless charging coil 233 is electrically connected to the circuit board 210. Thus, the multi-functional charging cable 10 can also realize wired charging and wireless charging functions, expanding the functionality of the multi-functional charging cable 10. For details, please refer to the above embodiment, which will not be repeated here.

[0085] As an example, circuit board 210 may include a second positive solder joint, a third positive solder joint, a second negative solder joint, a third negative solder joint, a second signal solder joint, a third signal solder joint, a third connection solder joint, and a fourth connection solder joint.

[0086] One end of the first power positive wire is electrically connected to the first connector 130, and the other end is electrically connected to the second positive solder joint; one end of the first power negative wire is electrically connected to the first connector 130, and the other end is electrically connected to the second negative solder joint; one end of the first wire signal wire is electrically connected to the first connector 130, and the other end is electrically connected to the second signal solder joint.

[0087] One end of the second power supply positive wire is electrically connected to the second connector 140, and the other end is electrically connected to the third positive solder joint; one end of the second power supply negative wire is electrically connected to the second connector 140, and the other end is electrically connected to the third negative solder joint; one end of the second wire signal wire is electrically connected to the second connector 140, and the other end is electrically connected to the third signal solder joint.

[0088] The wireless charging coil 233 can be electrically connected to the third connection solder point and the fourth connection solder point respectively. One of the third connection solder point and the fourth connection solder point can be electrically connected to the second positive solder point and the third positive solder point respectively through the lines on the circuit board 210. The other can be electrically connected to the second negative solder point and the third negative solder point respectively through the lines on the circuit board 210.

[0089] Understandably, a second signal line 150, a positive data line 115, and a negative data line 117 can also be connected between the first connector 130 and the second connector 140 to improve the charging power and expand the data transmission function of the multi-functional charging cable 10. For details, please refer to the above embodiments, which will not be repeated here.

[0090] In the multi-functional charging cable 10 provided in this application embodiment, by electrically connecting the first end and the second end of the positive power line 111, the negative power line 113, and the first signal line 121 to the first connector 130 and the second connector 140 respectively, the first signal line 121 can transmit the connector identification signal that a device is connected to the two connectors (i.e., the first connector 130 and the second connector 140), and the two connectors can realize wired charging function through the positive power line 111 and the negative power line 113. By electrically connecting the circuit board 210 to the electrical connection portion 119 between the first and second ends of the positive power line 111, the negative power line 113, and the first signal line 121, and electrically connecting the wireless charging coil 233 to the circuit board 210, the wireless charging coil 233 and the two connectors can share the positive power line 111, the negative power line 113, and the first signal line 121. The first signal line 121 can transmit a wireless charging identification signal indicating that the wireless charging coil 233 has a device connected. The first connector 130 or the second connector 140 can supply power to the wireless charging coil 233 through the positive power line 111 and the negative power line 113 to achieve wireless charging. Thus, the multi-functional charging cable 10 provided in this application embodiment can simultaneously achieve wired charging and wireless charging, expanding the functionality of the multi-functional charging cable 10 and better meeting the user's needs. Furthermore, since both the first connector 130 and the second connector 140 are connected to the same solder point on the circuit board 210 through the electrical connection portion 119 of the first signal line 121, there is no need to distinguish between the input and output of the first connector 130 and the second connector 140. Either the first connector 130 or the second connector 140 can be connected to a power supply device, while the other and the wireless charging coil 233 can both be connected to a power receiving device, which helps to realize blind insertion of each connector and provides a better user experience.
