Description

Technical Field

[0001] This invention belongs to the field of vehicle power supply accessories technology, specifically relating to a magnetic power supply device, which is particularly suitable for powering electrically heated gloves in cycling scenarios. Background Technology

[0002] Electric heated gloves, as an effective personal thermal protection device, are widely used in cold environments such as motorcycle riding. To overcome the limited battery life of built-in batteries, utilizing the vehicle's power supply for continuous power has become an ideal solution.

[0003] For example, utility model patent CN214258097U discloses an electrically heated glove, including a glove body and a circuit module. The circuit module is electrically connected to a heating element and a first connector, and also includes a power cord. The power cord includes a first power supply line and two second power supply lines. Each of the two second power supply lines is connected to one end of the first power supply line, and the other end of the first power supply line is electrically connected to a USB interface. The ends of the two second power supply lines furthest from the first power supply line are each electrically connected to a second connector. This solution connects to a USB interface on a motorcycle via a USB port, splitting the cord in two. Compared to a power adapter, this solution greatly simplifies the use of the electrically heated glove. Furthermore, the two first magnets and two second magnets are arranged with opposite polarities, thus fixing the connection direction of the first and second connectors. This prevents incorrect polarity connection after connecting the first and second connectors, eliminating the need for user intervention and making the process simple and quick.

[0004] However, through long-term research in the field of cycling safety, the inventors have discovered that the above-mentioned solution, which simply combines "power supply" with "magnetic connection", falls into a "safety paradox" in actual cycling scenarios: in order to achieve sufficient operational freedom, the power cord must be of a certain length; but this necessary and lengthy power cord itself becomes an unpredictable source of danger in complex cycling postures and emergency moments.

[0005] This demonstrates that current technologies focus solely on the convenience of connection and the ultimate "disconnectability," completely neglecting the safety issues inherent in the dynamic process from "connection" to "disconnection." Therefore, a safer, continuous power supply solution is urgently needed to meet the power demands of complex cycling scenarios. Summary of the Invention

[0006] The purpose of this invention is to provide a magnetic power supply device for electrically heated gloves, so as to partially alleviate or solve the above-mentioned problems and improve the comfort and safety of cycling gloves.

[0007] To solve the aforementioned technical problems, the present invention specifically adopts the following technical solution:

[0008] A magnetic power supply device includes a first cable management module, a second cable management module, a magnetic power supply module, and a power supply cable;

[0009] The first cable management module includes a housing, a counterweight, a pulley, a first magnetic component, and a second magnetic component. The pulley is fixed to the counterweight, the first magnetic component is disposed on the top of the counterweight, the counterweight is slidably disposed on the housing, and the second magnetic component is disposed on the top of the housing. The first magnetic component and the second magnetic component are configured to repel each other.

[0010] The second cable management module is provided with an installation cavity and a storage cavity;

[0011] The magnetic power supply module includes a second magnetic interface housed within the housing cavity;

[0012] The input end of the power supply line is connected to an external power source, and the output end of the power supply line passes through and is fixed at one position on the top of the housing, and passes through the pulley and exits at another position on the top of the housing to connect with the second magnetic interface.

[0013] When the first magnetic interface of the external device is connected to the second magnetic interface, the external device pulls the second magnetic interface away from the second cable management module. The power supply line drives the pulley to move in the first direction, and the first magnetic component moves closer to the second magnetic component, increasing the repulsive force between the first and second magnetic components. When the external device moves to a preset distance, the first and second magnetic interfaces are pulled apart. Under the action of the repulsive force, the counterweight, the pulley, and the first magnetic component move synchronously to reset in the second direction, wherein the first direction and the second direction are opposite.

[0014] As an improvement, a first channel is provided on the first side of the top of the housing, and a second channel is provided on the second side. An active space is provided inside the housing, and the counterweight is disposed in the active space. The first channel and the second channel are respectively connected to the active space. The output end of the power supply line is connected to the second magnetic interface by passing through the first channel, the active space and the second channel in sequence. The second side is the side closer to the second cable management module.

[0015] As an improvement, the outer shell is provided with two symmetrical sliding grooves along the axial direction, and two sliders that cooperate with the sliding grooves are respectively provided on both sides of the counterweight.

[0016] As an improvement, the pulley is provided with circumferential limit protrusions on both sides, and a limit groove is formed between the two limit protrusions, with at least a portion of the power supply line located in the limit groove.

[0017] As an improvement, a hollow conduit is provided between the first cable management module and the second cable management module. The conduit is a flexible pipe. The output end of the power supply line passes through the first cable management module, through the inside of the conduit, and then enters the second cable management module to connect with the second magnetic interface.

[0018] As an improvement, the first surface of the second cable management module is provided with at least two non-continuous first limiting members, which are arranged around the mounting cavity.

[0019] As an improvement, the second cable management module includes a first component and a second component. When the first component and the second component are fixed, the first component and the second component enclose the mounting cavity. One end of the first component and the second component are rotatably connected, and the other end is fixed by a fastener. When there is no fastener, the mounting cavity is an open cavity. When the first component and the second component are fixed by a fastener, the mounting cavity is closed on all sides.

[0020] As an improvement, the first cable management module is fixedly installed on a stationary part of the vehicle body; the second cable management module is fixedly installed on the vehicle handlebar; the angle α between the line connecting the first cable management module and the second cable management module and the handlebar axis is 20°-40°, and the angle α gradually decreases when the handlebar is turned in a third direction.

[0021] As an improvement, the magnetic power supply module further includes a first housing and a second housing, with the second magnetic interface disposed between the first housing and the second housing.

[0022] As an improvement, the inner diameter of the storage cavity gradually decreases from the side away from the first cable management module to the side closer to the first cable management module.

[0023] The principle and beneficial technical effects of this invention are as follows:

[0024] For cycling scenarios, this solution provides a modular automatic cable management device. Through modular first cable management module, second cable management module and magnetic power supply module, the power cable is always kept in an orderly and constrained state during use, preventing the power cable from interfering with the user and ensuring quick and reliable separation of the rider and bicycle in emergencies.

[0025] Specifically, through the modular first cable management module, second cable management module, magnetic power supply module, and cable conduit, the power supply cable does not interfere with the user's grip or operation area. In other words, the power supply cable is confined to the inside of the handlebar by multiple modules, ensuring that the power supply cable is always taut and controllable throughout the user's entire operating range. This completely avoids the risk of the cable drooping, swaying, and getting tangled with critical control components such as the brake and clutch (especially when turning and changing lanes, the tilt of the vehicle body will cause the scattered cables in the existing technology to sway, increasing the risk of tangling), greatly improving the normal safety during riding.

[0026] Furthermore, during use, users only need to wear heated gloves and naturally place their hands on the handlebars. The first magnetic interface on the gloves and the second magnetic interface on the magnetic power supply device automatically engage. When the user's hand leaves the handlebars and reaches the limit distance (usually 2-4cm), due to the pulley's restriction on the power supply line, the first and second magnetic interfaces automatically break free under the pull of the hand's force, thus achieving rapid separation. In other words, the automatic cable retraction mechanism can immediately retract the detached cable, effectively eliminating the fatal risk of obstruction or delay in detachment due to the "pre-winding" of the long cable in the existing technology (in the event of a crash, the direction of the cable's movement is usually disordered, and the cable may have already wrapped around the rider's wrist, arm, or vehicle parts before the gloves are separated from the cable, forming a "pre-winding").

[0027] Furthermore, on the one hand, the first cable management module, the second cable management module, the magnetic power supply module, and the cable conduit adopt a modular design, which facilitates disassembly and maintenance. On the other hand, the internal components of the second cable management module adopt a split design, which can match the handlebars of different sizes.

[0028] In summary, unlike the static thinking of existing technologies that only focus on "connection and disconnection", this invention introduces a split modular automatic cable retraction and extension device to achieve full-process management of the power cable from "connection" and "use" to "disconnection" and "recycling", which is especially suitable for riding needs in complex road conditions.

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] In this document, suffixes such as "module," "component," or "unit" used to denote elements are used solely for the purpose of illustrative purposes and have no specific meaning in themselves. Therefore, "module," "component," or "unit" may be used interchangeably. In this document, terms such as "upper," "lower," "inner," "outer," "front," "rear," "one end," and "the other end," indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] In this document, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. In this document, "multiple" means two or more, that is, it includes two, three, four, five, etc.

[0042] In this article, "first end" and "second end" are used to describe two opposite ends of the same component. "First end" usually refers to the end closer to a reference point. For example, in a counterweight, the first end refers to the end closer to the top of the shell; in the shell, the first end refers to the top of the shell. The second end of the power supply line refers to the end connected to the external power source, i.e., the input end, while the first end of the power supply line refers to the end connected to the magnetic power supply module, i.e., the output end.

[0043] In this document, "first direction" and "second direction" are used to describe two opposite directions. For example, the first direction is upward along the height direction of the outer shell (i.e., Figure 2 The direction indicated by the middle arrow a), the second direction is downward along the height direction of the outer shell (that is... Figure 2 (The direction indicated by the middle arrow b).

[0044] Example 1

[0045] See Figures 1-8 The present invention provides a magnetic power supply device, and particularly relates to a magnetic power supply device for an electric heating glove, comprising a first cable management module 100, a second cable management module 200, a magnetic power supply module 300, and a power supply cable 500.

[0046] The first cable management module 100 includes a housing 101, a counterweight 102, a pulley 103, a first magnetic element 104, and a second magnetic element 105. The pulley 103 is fixed to the counterweight 102 (e.g., by a pin or bearing). The first magnetic element 104 is disposed at the first end of the counterweight 102 (i.e.,...). Figure 2 The counterweight 102 is slidably disposed within the movable space 111 inside the housing 101 by means of a slider 107 thereon engaging with a groove 106 on the housing 101. The second magnetic component 105 is fixedly disposed at the first end of the housing 101 (i.e., the top of the counterweight). Figure 4 The upper interior of the outer shell), and its mounting polarity is configured to be the same as that of the first magnetic element 104, so that a repulsive magnetic force is generated between the two.

[0047] The second cable management module 200 includes a first component 201 and a second component 202. When the first component 201 and the second component 202 are locked and fixed by screws or other fasteners, they together form a mounting cavity 203 for accommodating the handle. At the same time, the first surface of the first component 201 (i.e., the side facing the user) is recessed inward to form a storage cavity 204 for storing part of the magnetic power supply module 300 when not in use.

[0048] The magnetic power supply module 300 includes a second magnetic interface 303. The second magnetic interface 303 internally contains electrical contacts and a magnet. In some embodiments, the magnetic power supply module 300 further includes a first housing 301 and a second housing 302 that can be interlocked, with the second magnetic interface 303 disposed between the two by injection molding or press-fitting. In some embodiments, the first magnetic element 104 and the second magnetic element 105 are permanent magnets.

[0049] In some embodiments, the second end of the power supply line 500 (not shown) is used to connect to an external power source such as a motorcycle battery or a USB interface. The first end of the power supply line 500 enters from the first end of the housing 101 (on one side of the upper end, such as the right side), that is, from one of the positions on the top of the housing, enters the active space 111, passes around the pulley 103, and then exits from the first end of the housing 101 (on the other side of the upper end, such as the left side, especially the side near the second cable management module), that is, from another position on the top of the housing, and finally connects to the electrical contacts of the second magnetic interface 303.

[0050] When the first magnetic interface of an external device (taking an electrically heated glove as an example) is connected to the second magnetic interface, the electrically heated glove pulls the second magnetic interface outward away from the second cable management module. The power supply line drives the pulley to move in the first direction a, and the repulsive force between the first magnetic component and the second magnetic component increases. When the electrically heated glove moves to a preset distance, the first magnetic interface and the second magnetic interface are pulled apart. Under the action of the repulsive force, the counterweight, the pulley, and the first magnetic component move synchronously in the second direction b to reset. The first direction a and the second direction b are opposite. That is, when the first magnetic interface of the electrically heated glove is connected to the second magnetic interface 303, the user's hand movement will pull the second magnetic interface 303 outward, thereby driving the pulley 103 and the counterweight 102 to move in the first direction (e.g., upward) through the power supply line 500. During this process, the distance between the first magnetic component 104 and the second magnetic component 105 decreases, and the repulsive force between them increases. This repulsive force is converted into a pull force on the second magnetic interface 303 through the power supply line 500, keeping the power supply line taut and preventing the cable from becoming loose and tangled. When the user's hand moves to a preset distance (e.g., 2-4cm), this pull force, together with the pulling force of the glove, overcomes the holding force of the magnetic interface, causing the first and second magnetic interfaces to be pulled apart. Once detached, the counterweight 102, pulley 103, and first magnetic component 104 immediately and synchronously move to the second direction (e.g., downward) to reset under the action of magnetic repulsion, quickly retracting the loosened power supply line. This core mechanism realizes automatic tensioning of the power supply line, forced disconnection at a safe distance, and instantaneous retraction after disconnection, fundamentally solving the core safety problems of cable tangling during riding and hindering separation of rider and bicycle in the event of a fall.

[0051] In some embodiments, a first channel 108 is provided on a first side (e.g., the top side) of the first end (upper end) of the housing 101, and a second channel 109 is provided on a second side (e.g., the left side). A through-space 111 is provided inside the housing 101. The counterweight 102 is disposed within this through-space 111. The first channel 108 and the second channel 109 are respectively connected to both ends of the through-space 111. During assembly, the first end of the power supply cable 500 passes sequentially through the first channel 108, the through-space 111, and the second channel 109, and then connects to the second magnetic interface 303. This provides a clear and smooth path for the power supply cable 500, ensuring that the cable can move smoothly with the pulley 103 within the through-space 111, avoiding random friction and wear between the cable and the inner wall of the housing 101, and improving the reliability and service life of the device.

[0052] In some embodiments, the outer casing 101 is symmetrically provided with two grooves 106 along its axial direction (i.e., the sliding direction of the counterweight). Correspondingly, two sliders 107 matching the shape of the grooves 106 are respectively provided on both sides of the counterweight 102. The sliders 107 are embedded in the grooves 106 to form a sliding pair.

[0053] In some embodiments, a limiting protrusion is provided circumferentially on both sides of the pulley 103, and an annular limiting groove is formed between the two limiting protrusions. In the assembled state, at least a portion of the power supply line 500 that passes around the pulley 103 (i.e., the line segment in contact with the pulley) is constrained within the limiting groove. By providing the limiting groove, the power supply line 500 can be effectively prevented from detaching from the pulley 103 or sliding to one side during the winding and unwinding process, ensuring the stability of the transmission relationship. At the same time, it makes the bending of the cable more regular, reduces local stress concentration, and improves the durability of the cable.

[0054] In some embodiments, a hollow conduit 400, which is a flexible conduit, is fixedly disposed between the first cable management module 100 and the second cable management module 200. The first end of the power supply cable 500 exits from the first cable management module 100, enters and passes through the interior of the conduit 400, and then exits from the other end of the conduit 400, entering the second cable management module 200 and connecting to the second magnetic interface 303. The conduit 400 completely encloses and hides the cables between the first and second cable management modules, achieving neat and organized vehicle wiring.

[0055] In some embodiments, at least two discontinuous first limiting members 205 (e.g., arc-shaped protrusions) are provided on the first surface of the first component 201 of the second cable management module 200. These first limiting members 205 are arranged circumferentially around the opening of the mounting cavity 203. When the second cable management module is mounted on a vehicle (e.g., a handlebar), the first limiting members allow the second cable management module to fit more closely to the handlebar, thereby improving stability; at the same time, the "discontinuous" design allows the second magnetic interface to enter the storage cavity without obstruction.

[0056] In some embodiments, the inner diameter of the storage cavity 204 gradually decreases from the side away from the first cable management module 100 to the side closer to the first cable management module 100. That is, the inner diameter of the storage cavity gradually decreases from its open end to its closed end to form a transition structure. In this way, no matter which direction the second magnetic interface returns to the storage cavity from, it can be smoothly reset under the guidance of the transition structure.

[0057] In some embodiments, a notch communicating with the receiving cavity 204 is formed between at least two of the first limiting members 205. Two of the first limiting members 205 located at the edge of the notch are provided with arc-shaped portions 206, wherein the height of the arc-shaped portions 206 gradually decreases from the side closer to the first component 201 to the side farther from the first component 201, such that the opening of the arc-shaped portions 206 faces obliquely upwards towards the first limiting member 205. Correspondingly, the outer diameter of the second magnetic interface 303, or the first housing 301, gradually increases from the side closer to the first component 201 to the side farther from the first component 201, and its edge closer to the first component 201 is chamfered or rounded, that is, its edge closer to the first component 201 has a smooth surface. When the user's hand wearing heated gloves naturally grips the handlebars, the first magnetic interface on the heated gloves will first contact the oblique surface of one or more of the arc-shaped portions 206. The arc-shaped portion 206 can effectively "capture" the second magnetic interface 303 approaching from different angles, and guide it smoothly into the receiving cavity, thus achieving smooth docking under low magnetic force. Simultaneously, if the second magnetic interface 303 is pulled out in an emergency, it retracts under the action of the first cable management module. This structure ensures that regardless of which direction the second magnetic interface 303 swings back, it can be smoothly guided into the receiving cavity, ready for the next use.

[0058] In some embodiments, the first cable management module is fixedly mounted on a stationary part of the vehicle body; the second cable management module is fixedly mounted on the vehicle handlebar; the angle α between the line connecting the first cable management module and the second cable management module (the storage cavity, or the second magnetic interface) and the handlebar axis is 20°-40°, and the angle α gradually decreases when the handlebar is turned in a third direction 60° (that is, the direction of rotation of the handlebar to increase the throttle). In actual use, the user can adjust the position of the second cable management module, that is, adjust the position of the second magnetic interface, according to their own usage habits and hand size by adjusting the tightness of the first and second components. By limiting the angle α between the line connecting the first cable management module and the second cable management module and the handle axis to 20°-40°, the cable conduit is in a relatively taut state in the initial state. As the user rotates the handle, the angle of the second cable management module also changes. At this time, the angle between the first cable management module and the second cable management module gradually decreases, and the cable conduit gradually loosens. This reduces the pulling sensation experienced by the user during handle rotation and prevents accidental breakage during handle rotation.

[0059] In some embodiments, the second component is provided with a second limiting member that cooperates with the first limiting member, and the first limiting member and the second limiting member together form a discontinuous annular limiting structure.

[0060] In some embodiments, the outer diameters of the first and second limiting members gradually decrease from the side closer to the second cable management module 200 to the side farther away from the second cable management module 200, that is, their outer contours gradually narrow, or their cross-sectional areas gradually decrease while remaining close to the handle, thereby achieving a smooth transition with the handle and improving the user's grip. Simultaneously, through reasonable spatial planning, the user's hand is forcibly constrained and guided to be in the optimal docking position when naturally gripping, thus compensating for the shortcomings of weaker magnetic interfaces in docking accuracy and anti-interference capabilities.

[0061] The magnetic power supply device with the above structure is actually a "restrictive" stretching power supply solution. First, it limits the stretching range of the power supply cable to prevent users from pulling it too long and causing riding risks such as entanglement. Furthermore, this solution limits the user's grip range through the first and second limiting members, ensuring that when the user naturally places their fingers on the clutch or brake and their palm on the handlebars, the first and second magnetic interfaces can be attracted within the magnetic range. In other words, by limiting and guiding the user's grip position, the two magnetic interfaces can be quickly connected within a controllable magnetic range (a large magnetic force is not conducive to breaking free).

[0062] In some embodiments, one end of the first component 201 and the second component 202 are rotatably connected via a pivot or hinge structure, while the other end is provided with a screw hole for locking and fixing with screws or other fasteners. When no fastener is used, the first component 201 can be opened around the pivot, making the mounting cavity 203 an open cavity, facilitating fixing or removal from the handle. When fasteners are used to fix the two components, the mounting cavity 203 is closed on all sides, securely encapsulating the handle inside. That is, the first component 201 and the second component 202 are opened and closed via a rotatable connection and fasteners. During installation or maintenance, the fasteners can be loosened to open the first component 201, making the mounting cavity 203 open, facilitating fixing or detachment from the handle. After installation, the fasteners are tightened to close the mounting cavity 203, securely encapsulating the handle inside, thus fixing the handle and the second cable management module.

[0063] This split-type rotating connection design greatly facilitates the assembly, maintenance, and replacement of the device. It allows the second cable management module 200 to be easily adapted and installed on handlebars of different diameters, improving the product's versatility and maintainability.

[0064] In some embodiments, two mounting protrusions 110 are provided on one sidewall of the housing 101 of the first cable management module 100. These mounting protrusions 110 may have through holes or threaded holes. By passing a strap (e.g., a thin wire) through the holes in the mounting protrusions 110, the entire first cable management module 100 can be securely mounted to the vehicle frame or other designated location. This modular mounting method is simple and reliable, facilitating arrangement and positioning within the vehicle.

[0065] In some embodiments, the electrically heated glove is provided with a first magnetic interface, which is located on the side of the glove body near the thumb on the index finger and corresponds to the proximal phalanx of the index finger.

[0066] In summary, for cycling scenarios, this solution provides a modular automatic cable management device. Through modular first cable management module, second cable management module and magnetic power supply module, the power cable is always kept in an orderly and constrained state during use, preventing the power cable from interfering with the user and ensuring quick and reliable separation of the rider and bicycle in emergencies.
