Description

Technical Field

[0001] This utility model relates to the field of automotive steering wheel technology, specifically a steering wheel ambient light that can uniformly guide light. Background Technology

[0002] The car steering wheel is an important component of the car steering system. A car is composed of thousands of tiny parts, and its progress and development are also made up of various subtle advancements and changes. In addition to grasping the trend of changes in cars from a macro perspective, we should also feel the changes brought about by the progress of cars from the details. The car steering wheel is such an important part. However, the traditional steering wheel is relatively monotonous in function and lacks ambient lighting and decoration.

[0003] Chinese utility model patent CN115123070A discloses a steering wheel with ambient lighting for new energy vehicles, including a fiber optic light strip. The fiber optic light strip is connected to a warning system and a welcome system via an MCU. The warning system includes intelligent driving warning, hands-off warning, and health warning. The warning methods of the system include vibration warning and light warning. A vibration motor is used for vibration warning, which has warning levels, and the vibration frequency of the motor changes according to the warning level. This invention features a door-opening welcome function, enhancing the driver's sense of belonging. The steering wheel ambient lighting, combined with the overall vehicle ambient lighting, provides a luxurious experience by changing brightness, color, and music rhythm. The steering wheel ambient lighting, combined with intelligent driving, effectively provides safe driving and health warnings. The combination of vibration and light warnings further enhances the driver's perception of warnings and improves their sense of safety.

[0004] During use, the device suffers from problems such as uneven light guidance and low light reflection efficiency. The unreasonable design of the light guiding structure leads to light attenuation and uneven refraction. Furthermore, the light guide strip and the light guide are not tightly attached, which can easily cause light loss. At the same time, the lack of effective reflective design affects the visual effect and light efficiency. Utility Model Content

[0023] (III) Beneficial Effects

[0024] Compared with the prior art, this utility model provides a steering wheel ambient light that can uniformly guide light, which has the following beneficial effects:

[0025] 1. This type of steering wheel ambient light with uniform light guidance achieves efficient light transmission and reflection by setting a light guide assembly containing a circuit board, a light source, a light guide strip, and a light guide between the base and the housing. The light guide strip is divided into a contact surface that closely adheres to the light guide and a non-contact surface with reflective teeth. Light emitted from the light source first enters the light guide strip. The contact surface ensures that the light is smoothly transmitted to the light guide, while the reflective teeth on the non-contact surface reflect the side light back into the light guide strip, preventing light loss and allowing the light to be transmitted more concentratedly through the light guide. In this way, a uniform light guiding effect is achieved, making the steering wheel ambient light emit a uniform and soft glow, effectively improving the atmosphere and visual appeal of the car interior, while avoiding areas that are too bright or too dark, thus avoiding negative impacts on the driving experience.

[0026] 2. This type of steering wheel ambient light with uniform light guidance features a groove in the base, with an electroplated aluminum reflective layer on the bottom surface of the groove. The reflective layer also has an integrated light-guiding pattern. Both the reflective layer and the light-guiding pattern allow for multiple reflections and refractions of light. When light travels through the light guide, it is redirected upon encountering the light-guiding pattern and reflective layer within the groove, further improving light utilization. This not only results in a more uniform light distribution but also enhances the brightness of the ambient light. While improving aesthetics, it ensures that the light better meets the needs of ambient lighting during nighttime driving, reducing energy consumption.

[0027] 3. This type of steering wheel ambient light with uniform light guidance features a groove in the base with a removable rubber pad inside. The light guide pattern is fixed on the rubber pad, and the rubber pad and light guide pattern are covered with a reflective layer made of a high-gloss reflective material. When light travels through the light guide strip, it is redirected when it encounters the light guide pattern and reflective layer in the groove, further improving light utilization. Furthermore, the rubber pad, over prolonged use, ensures a better fit between the light guide strip and the light guide, resulting in more uniform light distribution and reduced energy consumption.

[0046] Example 1:

[0047] This embodiment provides a steering wheel ambient light that can uniformly guide light, and has the following technical features.

[0048] Please see Figure 1-9 A steering wheel ambient light with uniform light guiding includes a base 200 and a housing 100. The base 200 is used to fix the device on the steering wheel.

[0049] A light guide assembly 300 is disposed between the housing 100 and the base 200. The light guide assembly 300 includes:

[0053] A light guide 340 is disposed on the housing 100, and the light guide 340 is attached to the light guide strip 330.

[0054] The light guide strip 330 includes a contact surface 331 and a non-contact surface 332. The contact surface 331 is tightly fitted to one side of the light guide 340, and the non-contact surface 332 has reflective teeth 333 on one side to reflect the light transmitted from one side of the light guide strip 330.

[0055] In an optional embodiment, a groove 210 is provided on the base 200, and a reflective layer is provided in the groove 210. At least one light guide pattern 220 is provided on the reflective layer. The light guide pattern 220 and the reflective layer are used to improve the reflection efficiency of the light guide strip 330.

[0056] In an optional embodiment, the light guide pattern 220 is an upwardly protruding rib, and the cross-sectional shape of the light guide pattern 220 includes a semi-circle or a polygon.

[0057] In an optional embodiment, the reflective layer is fixedly disposed on the bottom surface of the groove 210, and the light guide pattern 220 is an upwardly protruding structure integral with the groove 210.

[0058] In an optional embodiment, the reflective layer is an electroplated aluminum layer covering the bottom of the groove 210 and the light guide pattern 220.

[0059] In an optional embodiment, a through display slot 110 is provided on the housing 100, and a light guide 340 is connected to the inside of the display slot 110 to facilitate the transmission of light.

[0060] In an optional embodiment, the circuit board 310 is provided with a circuit housing 311 for protecting the components above the circuit board 310.

[0061] Working principle: The base 200 can be installed on the steering wheel with bolts or other common mounting structures. A circuit board 310 is fixed on the top of the base 200. The circuit board 310 can control the light source to turn on or off. The light source emits light. One side of the light guide strip 330 is attached to the light source, so that the light can be transmitted to the other end of the light guide strip 330. The reflective layer and light guide texture 220 of the mounting groove of the base 200 can reflect or refract the light back into the interior of the light guide strip 330. Then, through the tight fit between the light guide strip 330 and the light guide 340, the light can be transmitted from the interior of the light guide 340 and finally displayed on the steering wheel through the display slot 110.

[0062] In summary, this type of steering wheel ambient light with uniform light guidance achieves efficient light transmission and reflection by setting a light guide assembly 300, including a circuit board 310, a light source 320, a light guide strip 330, and a light guide 340, between the base 200 and the housing 100. The light guide strip 330 is divided into a contact surface 331 that closely adheres to the light guide 340 and a non-contact surface 332 with reflective teeth 333. Light emitted from the light source 320 first enters the light guide strip 330. The contact surface 331 ensures smooth light transmission to the light guide 340, while the reflective teeth 333 on the non-contact surface 332 reflect side light back into the light guide strip 330, preventing light loss and allowing the light to be transmitted more concentratedly through the light guide 340. This achieves uniform light guidance, resulting in a soft and even illumination of the steering wheel ambient light, effectively enhancing the interior atmosphere and visual appeal, while preventing areas from being too bright or too dark, thus avoiding negative impacts on the driving experience.

[0063] This type of steering wheel ambient light with uniform light guidance features a groove 210 on the base 200, an electroplated aluminum reflective layer on the bottom surface of the groove 210, and a light-guiding pattern 220 integrated with the groove 210 on the reflective layer. Both the reflective layer and the light-guiding pattern 220 can reflect and refract light multiple times. When light travels through the light guide strip 330, it is redirected upon encountering the light-guiding pattern 220 and the reflective layer within the groove 210, further improving light utilization. This not only makes the light distribution more uniform but also enhances the brightness of the ambient light. While improving aesthetics, it ensures that the light can better meet the needs of ambient lighting during nighttime driving, reducing energy consumption.
