[0002] Currently, car wheel covers mainly consist of wheel covers, badges, and metal clips, and their decorative effect is highly dependent on ambient light. At night or in low-light conditions, traditional wheel covers cannot actively emit light, resulting in a significant reduction in the vehicle's side visibility and failing to convey the brand's design language.
[0003] In related technologies, attempts have been made to improve visibility through reflective coatings, but the effect is passive and cannot achieve dynamic light emission or personalized display.
[0004] Therefore, there is a need to design a light-emitting device for wheel covers that can customize the type of light emission.
[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore, the above description is not considered to constitute information related to the technology. Utility Model Content

[0044] Research has revealed that current automotive wheel covers, primarily composed of wheel covers, badges, and metal clips, are highly dependent on ambient light for their decorative effect. In nighttime or low-light conditions, traditional wheel covers cannot actively emit light, significantly reducing the vehicle's side profile visibility. This not only fails to convey the brand's design language but also weakens the vehicle's passive safety.
[0045] Previous attempts to improve visibility using reflective coatings have yielded passive and limited results, failing to achieve dynamic illumination or personalized displays. The fundamental problem lies in the difficulty of maintaining a stable power supply to the rotating wheel hub environment, and the complex mechanical structure affecting the wheel's dynamic balance.
[0046] Therefore, there is an urgent need for a wheel cover structure that integrates reliable power supply and dynamic lighting functions.
[0047] The defects in the above solutions and the reasons for their occurrence are the results of the inventors' practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventors' contributions to this disclosure.
[0048] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0049] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0050] like Figure 1 and Figure 2 As shown, at least one embodiment provides a light-emitting device for a wheel cover, comprising:
[0051] The wheel cover 1 is injection molded from one of the following materials: ABS-PC, PA66-MD15, or PPE-PA. A 3mm deep positioning groove 10 is formed on its outer surface. The outer surface also has a positioning groove 10 for fixing an LED light strip 2. The LED light strip 2 is a COB light source strip with an IP67 protection rating, embedded in the positioning groove 10 through a silicone potting process. The light strips can be arranged in the shape of a brand logo to dynamically display brand information.
[0052] The power supply device 3, located at the inner axle of the wheel cover 1, is a miniature DC generator that generates electricity using the rotation of the wheel. The miniature DC generator includes a centrifugal trigger switch that automatically switches to battery power when the vehicle speed is below a threshold. One end of the centrifugal trigger switch is electrically connected to the power output terminal of the miniature DC generator; the other end is electrically connected to the power output terminal of the rechargeable battery; the common terminal of the centrifugal trigger switch is linearly connected to the power supply terminal of the LED light strip 2. When the vehicle speed is below or above the threshold, the centrifugal trigger switch switches the corresponding power supply terminal to either the rechargeable battery or the miniature DC generator. The miniature DC generator can achieve a self-generating mode. The generator has a built-in centrifugal switch that automatically switches to lithium battery power from the controller 4 when the vehicle speed is <5 km / h, ensuring that the lowest brightness mode is maintained when the vehicle is parked. The controller 4, located inside the wheel cover 1, is configured to be electrically connected to the power supply device 3 and the LED light strip 2 to send control signals for the LED light emission type. By installing LED light strips 2 on the outer side of the wheel cover 1 and power supply device 3 and controller 4 on the inner side, the appearance visibility of the wheel cover in low-light and no-light environments is greatly improved, increasing the vehicle's side passive safety under these conditions. The cooperation between power supply device 3 and controller 4 enables the customization of the wheel cover's illumination type.
[0053] The inner side of the wheel cover 1 has several mounting positions; one mounting position is used to mount the controller 4, and at least one other mounting position is used to mount the counterweight 5. The position of the counterweight 5 is adjustable to compensate for dynamic balance deviations caused by asymmetrically distributed electronic components. The counterweight 5 is made of tungsten alloy and is calibrated using a laser dynamic balancing tester.
[0054] The controller 4 has a built-in rechargeable battery and battery control module to maintain the operation of the LED light strip when the power supply is interrupted. The controller 4 supports wireless remote control of brightness, color, and dynamic effects. The controller 4 has a built-in main control chip and receives signals from mobile phones or vehicle terminals via Bluetooth 5.0 module to control the LED light strip 2 to be constantly lit in single color, flashing synchronously with the turn signals, or changing RGB gradient.
[0055] The controller 4 includes: a processor; a wireless module, which is a Bluetooth module and is electrically connected to the input terminal of the processor module; and an LED driving circuit, which is electrically connected to the output terminal of the processor module. The processor module is configured to: obtain the light emission type instruction received by the wireless module and send the LED light emission type control signal to the LED light strip 2 through the LED driving circuit.
[0056] Reference Appendix Figure 2In this embodiment, an external power supply mode is also provided. The power supply device 3 is an electric slip ring, which is connected to the vehicle's electrical system to obtain DC power. The electric slip ring is connected to the electrical interface at the end of the axle through a waterproof sealed bearing. The electric slip ring is coupled to the connector at the end of the axle through an O-ring fluororubber seal, directly drawing power from the vehicle's 12V system, thereby ensuring the stability of the power supply to the LED light strip 2.
[0057] Reference Appendix Figure 1 The positioning groove 10 is arranged in a U-shape, ring shape or brand logo shape, and the LED light strip 2 is embedded in the positioning groove 10 and led to the controller 4 through a wire.

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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0059] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships 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.
