Description

Technical Field

[0001] This utility model relates to the field of mobile terminal charging equipment technology, and in particular to a multi-functional charging cable. Background Technology

[0002] With the development of technology, mobile electronic devices, such as mobile phones, are becoming more and more popular. The mainstream mobile phone charging interfaces on the market include TYPE-C and Lightning Dock interfaces. Some terminal devices can also use wireless charging. Because the charging interfaces are not completely standardized, there is still a large market demand for multi-functional charging cables that can connect to two or three devices at once.

[0003] Existing dual-port or triple-port charging cables cannot directly meet the wireless charging needs of mobile devices, while ordinary wireless chargers only provide a single wireless charging function, resulting in relatively limited application scenarios. Furthermore, during use, unused ports on multi-port charging cables often become scattered, easily leading to tangling and knots, and potentially damaging internal circuitry due to frequent bending, thus affecting lifespan. Therefore, this invention proposes a multi-functional charging cable to at least partially solve the above problems. Utility Model Content

[0004] In view of the above problems, this utility model provides a multi-functional charging cable that overcomes or at least partially solves the above problems.

[0005] To address the aforementioned problems, this utility model discloses a multi-functional charging cable, comprising: The conversion unit in the middle has a power input interface connected to its first end via a wire, and at least one power output interface connected to its second end via a wire. The conversion unit is equipped with a wireless charging module.

[0006] Optionally, the power input interface is a USB-A interface or a TYPE-C interface.

[0007] Optionally, the power output interface includes a TYPE-C interface and a Lightning interface.

[0008] Optionally, a first magnetic attraction element is provided at the position of the first insulating part covered by the TYPE-C interface; A second magnetic element is provided at the position of the second insulating component covering the Lightning interface; The first magnetic attractor and the second magnetic attractor are compatible.

[0009] Optionally, the power output interface may also include a Micro-USB interface.

[0010] Optionally, a third magnetic element is provided at the location of the third insulating element covering the Micro-USB interface; The third magnetic attractor, the first magnetic attractor, and the second magnetic attractor are compatible.

[0011] The embodiments of this utility model have the following advantages: The conversion unit in the middle has a power input interface connected to its first end and at least one power output interface connected to its second end; the conversion unit also includes a wireless charging module. The power output interfaces may include a Type-C interface, a Lightning interface, and a Micro-USB interface, with compatible magnetic attachments on the insulating parts of each interface. This invention integrates wired and wireless charging functions, meeting the charging needs of different devices. The magnetic attachments also solve the problem of storing multiple interfaces, making it convenient to use and applicable to a wide range of scenarios. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of a multifunctional charging cable provided in one embodiment of the present invention.

[0013] The attached diagram is described below: 101. Conversion unit; 102. Power input interface; 103. TYPE-C interface; 104. Lightning interface; 105. Wireless charging module; 106. First insulating component; 107. Second insulating component. Detailed Implementation

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Reference Figure 1In some embodiments of this utility model, a multi-functional charging cable includes: a conversion unit 101 in the middle, with a power input interface 102 connected to its first end via a wire, and at least one power output interface connected to its second end via a wire; the conversion unit is equipped with a wireless charging module 105. Integrating wired and wireless charging functions into the same charging cable retains the convenience of multi-interface wired charging while adding wireless charging functionality, solving the problem of single-function traditional charging cables and wireless chargers. For example, when a user goes out, they only need to carry this multi-functional charging cable to provide wireless charging for a mobile phone that supports wireless charging, while simultaneously charging a tablet computer via a wired interface. The power input interface 102 is a USB-A interface or a Type-C interface 103. Using a USB-A interface or a Type-C interface 103 as the power input interface ensures compatibility with most power adapters, computer USB ports, and other power supply devices on the market, improving the product's versatility. For example, a user can plug the USB-A interface of this charging cable into a home charger, a car USB port, or a laptop USB port to obtain power.

[0016] The power output interfaces include a TYPE-C interface 103 and a Lightning interface 104. It provides both TYPE-C and Lightning Dock interfaces, satisfying the wired charging needs of Android and Apple devices respectively, eliminating the need to carry multiple charging cables with different interfaces. Specifically, the TYPE-C interface 103 has a first magnetic attachment at position 106 of its first insulating component; the Lightning interface 104 has a second magnetic attachment at position 107 of its second insulating component; the first and second magnetic attachments are compatible. Users can simultaneously power an Android phone (TYPE-C interface 103) and an Apple Watch charging dock (Lightning interface 104). The magnetic attachments allow unused interfaces to attract each other, solving the problem of tangled and inconvenient storage of multi-interface charging cables, while also reducing damage caused by careless placement of interfaces.

[0017] The power output interface also includes a Micro-USB port. The addition of a Micro-USB port allows for compatibility with more older devices (such as some e-readers and Bluetooth speakers), further expanding the product's applicability. For example, users can simultaneously charge a fitness tracker with a Micro-USB port and a tablet with a Type-C port.

[0018] A third magnetic clasp is located at the position of the third insulating component covering the Micro-USB interface; the third magnetic clasp, the first magnetic clasp, and the second magnetic clasp are compatible. When there are three power output interfaces, the insulating components of the two side interfaces are respectively equipped with magnets of opposite polarity; the insulating component of the middle interface is equipped with a non-magnetic soft magnetic material. When any connector is used for charging, the other two connectors can be magnetically attracted to each other, preventing the remaining two charging connectors from being placed haphazardly. The three interfaces are compatible with each other through magnetic clasps, ensuring that when any interface is used, the other two can be neatly stored, keeping the charging cable tidy and extending its service life. When using the middle Micro-USB interface, the TYPE-C interfaces 103 and Lightning interfaces 104 on both sides can be magnetically attracted to each other, preventing the two interfaces from shaking and causing cable fatigue.

[0019] It should be noted that when there are multiple power output interfaces, such as two or three, they can be of the same type, such as TYPE-C interface 103, or they can be different types of interfaces. That is, the output interfaces can be two or more TYPE-C interfaces 103, or they can be of different types, such as one TYPE-C interface 103 and one Lightning interface 104. The Lightning interface 104 is the Lightning Dock interface.

[0020] In some embodiments of this application, a multi-functional charging cable includes a conversion unit 101 in the middle, with a first end connected to a power input interface 102 via a wire, and a second end connected to at least one power output interface via a wire; the conversion unit is equipped with a wireless charging module 105. The power input interface is a USB-A interface 102, suitable for connecting to a conventional power adapter or a computer USB port.

[0021] The power output interfaces include a TYPE-C interface 103 and a Lightning interface 104, which can provide wired charging for Android devices and Apple devices, respectively. A first magnetic element is provided at the position of the first insulating member 106 covering the TYPE-C interface 103; a second magnetic element is provided at the position of the second insulating member 107 covering the Lightning interface 104. The first and second magnetic elements are compatible, allowing unused interfaces to attract each other for easy storage.

[0022] The power output interface also includes a Micro-USB interface for compatibility with more older devices. A third magnetic element is located at the third insulating part covering the Micro-USB interface. The third magnetic element, the first magnetic element, and the second magnetic element are compatible. When three power output interfaces are provided, the insulating parts of the two side interfaces are respectively equipped with magnets of opposite polarity, while the insulating part of the middle interface is equipped with a non-magnetic soft magnetic material. This allows the other two interfaces to attract each other when any one connector is in use, preventing clutter.

[0023] The beneficial effects of this utility model are as follows: by setting a wireless charging module in the conversion unit, the charging cable can have both wired and wireless charging functions, greatly expanding the application scenarios; the design of multiple types of power output interfaces can meet the charging needs of different devices; the setting of magnetic parts solves the problem of inconvenient storage of multi-interface charging cables, making the product more convenient to use and longer in life.

[0024] like Figure 1 As shown, the multi-functional charging cable disclosed in this utility model includes a conversion unit 101 in the middle, which integrates a circuit conversion module and a wireless charging module 105. The first end of the conversion unit 101 is connected to a power input interface 102 via a wire. In this embodiment, the power input interface 102 adopts a USB-A interface, which can be connected to a conventional power adapter or a computer USB port.

[0025] The second end of the conversion unit 101 is connected to two power output ports, a TYPE-C port 103 and a Lightning port 104, via wires. The TYPE-C port 103 can be used to charge Android phones, tablets, and other devices that support TYPE-C charging, while the Lightning port 104 is suitable for wired charging of Apple phones, tablets, and other devices.

[0026] A first magnetic attractor (not shown in the figure) is embedded inside the first insulating component 106 covering the TYPE-C interface 103, and a second magnetic attractor (not shown in the figure) is embedded inside the second insulating component 107 covering the Lightning interface 104. The first and second magnetic attractors are permanent magnets with opposite polarities. When one interface is not in use, the two interfaces can be magnetically attracted together to prevent cable tangling. The wireless charging module 105 on the conversion unit 101 uses electromagnetic induction wireless charging technology, conforming to the Qi wireless charging standard. When charging a device that supports wireless charging, simply place the device in the wireless charging area of ​​the conversion unit 101 to achieve wireless charging without the need for an additional wired connection.

[0027] In another embodiment, the second end of the conversion unit 101 is also connected to a Micro-USB interface as a third power output interface to be compatible with more older devices. The third insulating component covering the Micro-USB interface contains a third magnetic component made of soft magnetic material, which can attract the first and second magnetic components. When any one of the three interfaces is used, the other two interfaces can attract each other through magnetic attraction, keeping the cables tidy.

[0028] When using this multi-functional charging cable, connect the power input interface 102 to a power source, select the appropriate wired interface according to the device type, or directly place a device that supports wireless charging on the conversion unit 101 to achieve the charging function. Unused interfaces are magnetically stored together to avoid tangling and damage.

[0029] For example, the wireless charging module 104 mentioned above refers to a module that achieves wireless power transmission using methods such as electromagnetic induction, magnetic resonance, or radio waves. Preferably, it is a Qi-compliant electromagnetic induction wireless charging module with an operating frequency of 110-205kHz and an output power of 5-15W. The conversion unit 101 should internally include a circuit conversion module for converting the input electrical energy into voltage and current suitable for each power output interface and the wireless charging module, and should have overcurrent protection, overvoltage protection, and short-circuit protection functions. The magnetic attractors can be neodymium iron boron permanent magnets or ferrite magnets. The first and second magnetic attractors have opposite magnetic properties (one is the N pole, the other is the S pole) to ensure mutual attraction. The magnetic force of the magnetic attractors should be moderate enough to maintain the interface's attraction state without affecting the charging function; for example, a magnet with a magnetic strength of 50-200 Gauss is preferred. The wires connecting each interface to the conversion unit are preferably shielded wires containing at least two power wires and one ground wire, with an outer diameter of 2-5mm, possessing good flexibility and bending resistance, and capable of withstanding at least 5000 bending tests; the aforementioned wireless charging module 105 is integrated inside the conversion unit, such as... Figure 1 As shown, the coil position should be clearly marked on the surface of the conversion unit to facilitate accurate placement of the device to be charged by the user. When there are three power output interfaces, the three interfaces should be arranged radially, and the length of each cable should be the same (preferably 10-30cm) to ensure that they can be naturally magnetically attached together when stored.

[0030] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
