Description

Technical Field

[0001] This utility model relates to the field of vehicle auxiliary lighting technology, and in particular to a magnetic induction hub lamp system. Background Technology

[0002] Wheel hub lights are lights installed on the wheel hubs. Installing wheel hub lights serves to enhance the vehicle's appearance and also increases visibility on the road. Most wheel hub lights currently on the market are powered by solar energy, but solar cells are relatively expensive to use.

[0003] Currently, some wheel hub lights utilize the principle of magnetic induction, including a magnet and a power generation structure. The magnet is installed at the wheel arch, while the power generation structure is mounted on the wheel hub. During vehicle operation, due to the shock absorption system, the tire and wheel arch may shift vertically, causing instability in the relative distance between the magnet and the power generation structure. This is detrimental to stable power generation and may even pose a risk of the magnet detaching under extreme road conditions. Utility Model Content

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and 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 this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] This utility model provides a magnetic induction hub lamp system, including a magnetic component 1, a magnetoelectric conversion unit 2 and a flexible light effect module 3, wherein the magnetic component 1 is installed at the stationary part of the vehicle braking system to keep the magnetic component 1 relatively stationary.

[0037] The magnetoelectric conversion unit 2 is installed on the inner wall of the wheel hub 7 and can rotate with the wheel hub 7. The magnetoelectric conversion unit 2 contains a magnetic induction generator coil, which is the core component of the unit. This coil moves relative to the magnetic component 1 during vehicle operation to generate an induced current. The magnetic induction generator coil is made of a high-efficiency conductive material (such as copper wire) and has an optimized number of turns to maximize the electromagnetic induction effect and improve current generation efficiency. The magnetoelectric conversion unit 2 also includes a capacitor, a bridge rectifier, a Zener diode, a photosensitive switch, and a vibration switch. The capacitor smooths fluctuations in the induced current, stores and releases electrical energy to provide a stable DC voltage output. The bridge rectifier converts alternating current to direct current to ensure a stable and correct output voltage. The Zener diode limits the maximum voltage of the current, protecting other components in the circuit from overvoltage damage. The photosensitive switch controls the switching state of the circuit based on the external light intensity. The vibration switch automatically controls the switching state of the circuit based on the vehicle's movement state (such as starting, stopping, accelerating, etc.).

[0038] The flexible light effect module 3 is installed on the wheel hub spokes or wheel hub beam. The flexible light effect module 3 is electrically connected to the magnetoelectric conversion unit 2. The flexible light effect module 3 can receive induced current to emit light, which can make the wheel display circumferential light effect and improve visual cueing performance. The magnetic induction wheel hub light system provided by this utility model has a magnetic component 1 installed at the stationary part of the vehicle braking system and a magnetoelectric conversion unit 2 installed on the inner wall of the wheel hub 7. This can effectively avoid the positional displacement caused by shock absorption movement when installed at the wheel arch position, and ensure the relative stability between the magnetic component 1 and the magnetoelectric conversion unit 2. During the vehicle's movement, the relative movement between the magnetoelectric conversion unit 2 and the magnetic component 1 will generate an induced current. The flexible light effect module 3 will receive the induced current to emit light, thereby achieving self-illumination without the need for an external power supply or battery.

[0039] As an optional implementation, a light domain control cover 6 is also included. The light domain control cover 6 is installed on the outside of the wheel hub 7 and covers the flexible light effect module 3. The light domain control cover 6 is generally hollow and disc-shaped. The edge of the light domain control cover 6 is slightly larger than the area of ​​the wheel hub 7 where the flexible light effect module 3 is located. In order to cover the flexible light effect module 3 inside the light domain control cover 6, the light domain control cover 6 is provided with a light-transmitting area and a light-blocking area. The light emitted by the flexible light effect module 3 can pass through the light-transmitting area, and the light-blocking area can block the light emitted by the flexible light effect module 3. The light domain control cover 6 is used to work with the flexible light effect module 3 to form a variety of visual effects. The material of the light control cover 6 can be polycarbonate (PC) or acrylic sheet, which has excellent light transmittance, impact resistance and weather resistance; the outer edge of the light control cover 6 can be equipped with a dustproof sealing ring or anti-spin baffle to improve air turbulence and stability; the shape or pattern on the light-transmitting area and the light-blocking area can be formed into a "partially light-transmitting, partially light-blocking" pattern through laser engraving, spraying, light-blocking coating and other processes to control the shape of light distribution.

[0040] As an alternative implementation, see [link to implementation details]. Figure 2 The light control cover 6 is connected to the hub 7 via a fastener 61, which can be a screw, clip, adhesive, or magnetic structure, allowing the light control cover 6 to rotate synchronously with the hub 7. This is suitable for displaying fixed patterns, brand logos, warning signs, etc. The pattern rotates with the hub 7, making it suitable for simple decorations and dynamic visual signs. This structure is highly reliable, low-cost, easy to install, and highly stable.

[0041] As an alternative implementation, see [link to implementation details]. Figure 3 The light domain control cover 6 is mounted on the outer side of the hub 7 via a ball bearing assembly 62, forming a low-friction rotational connection. The inner side of the light domain control cover 6 is equipped with one or more of the following: a damper 63 (which can be a damping sheet, silicone ring, magnetic sleeve, etc.), an eccentric counterweight 64, and an elastic washer. The rotational speed of the light domain control cover 6 is less than the rotational speed of the hub 7. The light domain control cover 6 can rotate slowly due to inertial lag during the rapid rotation of the hub 7, creating dynamic light effects. For example, the pattern rotation rate is lower than that of the hub 7, achieving dynamic pattern effects such as "halo drift" and "pattern carousel"; the visuals are rich and artistic. Specifically, the outer side of the outer protrusion of the hub 7 mates with the inner ring of the ball bearing assembly 62, and the inner ring of the light domain control cover 6 mates with the outer ring of the ball bearing assembly 62. The damper 63 or the eccentric counterweight 64 can be connected at the connection between the light domain control cover 6 and the hub 7, or the eccentric counterweight 64 can be mounted on the inner edge of the light domain control cover 6.

[0042] As an alternative implementation, see [link to implementation details]. Figure 4The light domain control cover 6 is mounted on the outside of the wheel hub 7 via a dual bearing assembly 65. A self-balancing counterweight structure 66 and / or an anti-rotation limiting structure 67 are installed on the inside of the light domain control cover 6. When the wheel hub 7 rotates, the light domain control cover 6 remains stationary relative to the vehicle body. Due to inertia and the counterweight, the light domain control cover 6 maintains its orientation, creating a strong visual contrast effect of "static pattern, rotating background." The balancing counterweight structure 66 is located on the lower inner side of the light domain control cover 6, automatically maintaining its center of gravity in a stable direction, allowing it to remain relatively stationary during high-speed rotation. The anti-rotation limiting structure 67 can be a magnetic levitation plate / weak spring structure, providing limiting support to prevent the pattern from shifting direction, thus achieving a floating visual effect where the pattern remains stable and the background rotates. The pattern on the light domain control cover 6 always faces the direction of travel or remains upward, with the background glowing and flowing around it; the visual impact is extremely strong, possessing brand identification value.

[0043] The light domain control cover 6 and the flexible light effect module 3 form a "relative motion" relationship. Regardless of whether the light domain control cover 6 is stationary, slowly rotating, or synchronously rotating, it can generate a variety of light emission modes through the displacement difference between its graphic light-transmitting area and the flexible light effect module 3, including but not limited to the above three forms: static pattern + ring light; pattern gradient rotation; dynamic icon breathing, etc. It has a strong visual expression and differentiated design space, and is suitable for personalized modification, brand display and night driving safety prompts.

[0044] As an optional implementation, the magnetic component 1 includes multiple sheet magnets, all of which are stacked sequentially. The thickness of the magnetic component 1 can be adjusted by stacking the number of sheet magnets, allowing it to be positioned as close as possible to the magnetoelectric conversion unit 2. This reduces the magnetic flux gap, achieving a minimum magnetic gap to improve magnetic flux utilization and magnetic induction efficiency, thereby increasing power generation per unit rotation cycle and enhancing the overall power output performance of the system. This significantly improves the system's power generation efficiency and reliability. The sheet magnets can be made of high-strength magnetic materials, such as N52 grade, to enhance magnetic flux density and improve power generation efficiency.

[0045] As an optional implementation, the magnetic component 1 is fixed to the outside of the vehicle's brake caliper to form a stable magnetic induction structure with the magnetoelectric conversion unit 2 located on the inner wall of the wheel hub 7. This location is close to the brake pads, where fine metal shavings or iron oxide powder are generated during vehicle braking. The magnetic component 1 can simultaneously adsorb ferromagnetic dust, reducing its adhesion to the surface of the wheel hub 7, thereby improving the cleanliness and visual effect of the wheel hub 7, providing an additional cleaning function. Alternatively, the magnetic component 1 can be installed on the outside of the vehicle's brake caliper via a switching structure. This switching structure can move the magnetic component 1 and control its operating state. The switching structure can be operated manually or remotely to slide the magnetic component 1 into or out of the power generation area. In the outward state, the magnetic component 1 avoids the rotation trajectory of the magnetoelectric conversion unit 2, forming a demagnetized state, preventing the magnetoelectric conversion unit 2 from generating induced current, thus temporarily turning off the wheel hub light function. Both the magnetic component 1 and the magnetoelectric conversion unit 2 are concealed inside the wheel hub 7, without affecting the original appearance of the vehicle.

[0046] As an optional implementation, the flexible light effect module 3 is a side-emitting structure; the outer surface of the flexible light effect module 3 can be sprayed with paint of the same color as the wheel hub 7 or pasted with the same color adhesive strip to achieve visual camouflage; the flexible light effect module 3 is covered with a heat-shrinkable protective sleeve to effectively block dust and moisture, and is suitable for various climates and road conditions.

[0047] As an optional implementation, it also includes a busbar structure 5 and a flexible wiring structure 4. Multiple magnetoelectric conversion units 2 are connected in parallel through the busbar structure 5. A single flexible light effect module 3 can be adapted to two or more magnetoelectric conversion units 2 to enhance the luminous brightness and response speed of the flexible light effect module 3, which has strong scalability. The magnetoelectric conversion units 2 and the flexible light effect module 3 are connected through the flexible wiring structure 4, and the length of the flexible wiring structure 4 is telescopic. The flexible wiring structure 4 is used to adjust the installation distance between the magnetoelectric conversion units 2 and the flexible light effect module 3, and is adapted to the wheel hub structure of different vehicles.

[0048] As an optional implementation, an intelligent remote control device is also included. The flexible light effect module 3 is equipped with a wireless communication element, and the intelligent remote control device is wirelessly connected to this element. The intelligent remote control device can remotely control the emitted color, brightness, or flicker frequency of the flexible light effect module 3. The intelligent remote control device can be a smartphone or a vehicle-mounted central control system, enabling personalized remote control of parameters such as light color, brightness, and flicker frequency, thereby further enhancing visual appeal and interactivity. This structure can be connected as an expansion module based on existing systems without affecting the system's basic power generation and emission functions.

[0049] This utility model relates to a magnetic induction hub lamp system. A light domain control cover 6 is installed on the outside of the hub 7, controlling the light output pattern of the flexible light effect module 3 through pattern shading and changes in motion. A magnetic component 1 is fixed to a stationary part of the vehicle's braking system. A magnetoelectric conversion unit 2 generates electricity by cutting magnetic lines of force as the hub 7 rotates, illuminating the flexible light effect module 3. By incorporating a Zener diode, photosensitive switch, and vibration switch, the system not only improves the stability of electrical energy but also automatically adjusts the circuit's operating state according to the external environment, achieving intelligent control and enhancing the system's adaptability and reliability. The flexible light effect module 3 adopts a side-emitting structure, providing good camouflage and installation flexibility. Its outer layer is covered with a heat-shrinkable protective sleeve, offering good protection. Compared to existing hub lamp solutions, this structure requires no battery, does not affect the appearance, provides significant luminous effect, is easy to install, and has strong adaptability and expandability, making it suitable for personalized vehicle decoration and nighttime driving safety warnings.

[0050] Through a simplified design combining structure and materials, this wheel hub lighting system achieves more efficient light output and a more easily manufactured appearance. Furthermore, it breaks away from structural confinement, allowing for modular independence and providing excellent modular expansion capabilities and adaptability to different vehicle models and environments.

[0051] Utilizing the principle of magnetic induction to generate electricity eliminates the need for battery replacement or vehicle power connection, thus resolving battery aging issues and the safety hazards associated with modifying vehicle electrical circuits. The magnetoelectric conversion unit 2 employs a magnetic induction power generation coil in its circuit structure, ensuring stable output power through a combination of appropriate capacitors and a bridge rectifier. Furthermore, the addition of Zener diodes, photosensitive switches, and vibration switches further enhances the circuit's adaptability, enabling it to cope with various environmental changes (such as light and vibration), ensuring the flexible light-effect module 3 operates normally under all conditions.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
