Background Art

[0002] Intelligence is the main theme of the development of the automotive industry today. Consumers are no longer limited to the demand for exquisite car exterior design, but are increasingly favoring intelligent surface decoration design that integrates functionality and decorativeness.

[0003] In recent years, an increasing number of concept cars from OEMs at auto shows both domestically and internationally have showcased designers' visions for future automotive interior cockpits. Future automotive interiors are expected to evolve towards intelligence, particularly in terms of overall visual, tactile, and interactive feedback. Interior design is shifting from traditional decorative elements to intelligent decorative surfaces that combine both decoration and functionality. Beyond the texture, tactile feel, and formability of traditional decorative materials, intelligent decorative surfaces can also incorporate interactive features such as optoelectronic dynamic display, touch, and voice control, representing a highly integrated decorative technology. Combining the light-transmitting and decorative properties of a material is a prerequisite for achieving intelligent decoration. Therefore, the development of intelligent interior surface decoration technology is trending towards the integration of soft, light-transmitting decorative materials with optoelectronic display functions equipped with control logic (e.g., translucent leather and translucent fabrics).

It also provides feedback on touch actions, such as vibration or sound prompts. However, existing surface ambient lights have numerous hardware flaws. In limited ambient light conditions, they cannot quickly locate touch areas or identify the corresponding functions of each touch area, making them inconvenient to use. Utility Model Content

[0041] Example:

[0042] like Figures 1 to 3 As shown, this embodiment provides a surface touch-type car atmosphere light, including: a fixing frame, a light source assembly, a touch assembly 6 and a covering layer; the touch assembly 6 and the light source assembly are arranged on the fixing frame, and the covering layer is covered on the fixing frame; the covering layer includes a translucent surface 5, which is arranged corresponding to the area where the touch assembly 6 is located, and a preset pattern 501 is arranged on the translucent surface 5; the touch assembly 6 includes a touch button 10, a PCBA board 9 and a backlight unit 11, the PCBA board 9 is electrically connected to the touch button 10, and the backlight unit 11 and the light source assembly are electrically connected to the PCBA board 9; the touch button 10 is arranged under the translucent surface 5, and the backlight unit 11 is used to illuminate the preset pattern 501 on the translucent surface 5.

[0043] The cladding layer further comprises a cover 3, which is formed by the cover 3 and the light-transmitting surface 5. The touch button 10 is an FPC button, and the distance between the touch surface on the light-transmitting surface 5 and the FPC button is less than or equal to 3 mm.

[0044] The mounting frame includes a frame 4 and an external bottom shell 7. The frame 4 is mounted on the external bottom shell 7, and the cladding layer is mounted on the frame 4. The light source assembly and the touch assembly 6 are mounted on the frame. The light source assembly includes a light source, a light guide 2, and a light guide bracket 1. The light guide bracket 1 and the light source are mounted on the frame 4, and the light guide 2 is mounted on the light guide bracket 1. The light source is located at the light input end of the light guide 2.

[0045] The touch assembly 6 also includes a transparent upper cover 12 and a bottom cover 8. A PCBA board 9 and a backlight unit 11 are disposed within the bottom cover 8. The transparent upper cover 12 is disposed at the open end of the bottom cover 8. The backlight unit 11 is positioned closely adjacent to the transparent upper cover 12, and the translucent surface 5 covers the transparent upper cover 12. The touch assembly 6 also includes a single-chip microcomputer (MCU). The MCU is electrically connected to the PCBA board 9, and the light source assembly is electrically connected to the PCBA board 9. The touch assembly 6 also includes a vibration unit electrically connected to the PCBA board 9. The touch assembly 6 also includes an audio unit electrically connected to the PCBA board 9.

[0046] This embodiment also provides a car, including the above-mentioned surface atmosphere light.

[0047] The touch button generates a touch signal, which, via I2C communication, controls the brightness and color of the two ambient light heads. These changes are displayed on the product's light-emitting surface. The touch button also vibrates when touched, providing feedback and sound. An LED light bead at the bottom of the touch button illuminates when touched, emitting light through the surface. This illuminates the touched area.

[0048] The overall structure consists of two major parts: the shell component and the touch component.

[0049] like Figure 1 As shown, the housing assembly is formed into a whole by a light guide support 1 , a light guide 2 , a skin 3 , a skeleton 4 , a light-transmitting surface 5 , a touch assembly 6 and an external bottom shell 7 .

[0050] like Figure 2 As shown, the touch assembly 6 is composed of five components.

[0051] The touch assembly 6 includes a PCBA board, which mainly includes chips and electronic components.

[0052] The touch component 6 is the core of the entire electronic control, and is mainly composed of a single-chip microcomputer, a touch panel, a backlight LED, a PCB, a transparent upper cover and a bottom cover.

[0053] The transparent upper cover 12 is mainly used to transmit light to the translucent surface 5 after the LED is lit, so that the preset pattern 501 on the translucent surface 5 can be illuminated. At the same time, the FPC touch button is tightly attached to the bottom of the lit translucent surface 5. The voltage signal generated when the FPC touch button is pressed is transmitted to the inside of the single-chip microcomputer through the FPC, so that the single-chip microcomputer responds to this control touch signal. The distance between the entire touch surface and the FPC is controlled to not exceed 3mm, so that the touch signal can be transmitted to the inside of the single-chip microcomputer. The single-chip microcomputer transmits a signal to the atmosphere lamp head through the Lin signal line. There is a control chip inside. After receiving the signal from the touch component 6, it can control the output accordingly in real time, thereby realizing the change of brightness and color and achieving the atmosphere lamp effect.

[0054] The upper and lower covers of the touch assembly 6 are secured by snapping together, and the internal PCB is pressed and stabilized.

[0055] To further enhance consumer perception of automotive quality, the concept of soft, intelligent surface decoration with optoelectronic display functionality has emerged. Due to differences in soft leather material properties and formulation design, its ability to achieve good light transmission is inferior to that of hard decorative materials. Due to the difficulty of developing translucent leather materials with good light transmission, mass production examples combining soft materials with optoelectronic display functionality are rare. These applications are only seen in the Great Wall Haval H6 and Sihao X8 models, and both were developed by foreign leather manufacturers, resulting in long development cycles and high material costs.

[0056] Translucent leather products are currently shifting from full light transmission requirements to high-resolution display of localized patterns, placing higher demands on the layout of the pattern layer. When the pattern layer is far from the display layer, the resolution decreases after the light passes through the multiple layers of dielectric material. However, when the pattern layer is closer to the display layer, the light-colored translucent leather cannot cover the pattern layer, resulting in a shadow cast by the pattern layer when not illuminated. Therefore, the difficulty in the application of translucent leather lies in the design and production of patterns close to the display surface. Conventional pattern design methods involve spraying a masking layer on the inside of the covering frame and then laser engraving or printing the pattern. However, this method is costly, requires a long processing cycle, and results in low pattern resolution. After the light passes through the pattern layer, it must pass through the adhesive layer, base fabric layer, and surface layer, which can easily cause light scattering, resulting in reduced display resolution and blurred patterns. To ensure clear pattern display, the pattern layer should be preferably placed between the dense layer and the foam layer or base fabric layer of the translucent leather, and the dense layer should be of a certain thickness. This pattern layout method reduces the blurring caused by light diffusion after the light passes through the pattern layer, thereby improving the display resolution.

[0057] In the traditional leather production process, the existing leather production equipment and production processes all complete the composite of the base fabric and the leather layer during the production process. If the pattern layer layout requirements need to be met, leather manufacturers need to adjust the existing leather production process and production line layout. In the traditional production process, the pattern layer manufacturing process (such as digital printing, screen printing, pattern roller printing, etc.) is added. The production process of translucent materials with pattern layers is relatively complicated, and it is necessary to consider the shielding properties of the pattern layer and the effect of thermal stretching on the tensile deformation of the pattern layer during the production process. In addition, the light transmittance of different materials and structures varies greatly. Light transmittance is the ability of light to pass through a medium. It is the main indicator for evaluating the light transmission effect. It is usually characterized by transmittance, which is the percentage of the luminous flux passing through the medium to its incident luminous flux.

[0058] For leather materials, there are two main factors that affect light transmittance: a. Light absorption. When light passes through a medium, it causes valence electron transitions or atomic vibrations to consume energy. When light absorbs photoelectron energy but does not de-excite and emit photons, it collides with other molecules during motion, causing light energy to attenuate. b. Light scattering. For multiphase blends, scattering is the main factor that causes a decrease in light transmittance, and it is unavoidable. When incident light passes through a crystalline area or a crystalline additive, it is neither transmitted nor reflected nor absorbed, but dissipated in the form of scattering, resulting in a decrease in light transmittance.

[0059] When there are many crystalline additives in the translucent leather structure, or when the crystallinity is high and the density of the crystalline area is significantly higher than that of the non-crystalline area, the transmittance drops significantly. Therefore, there are three differences between translucent leather and ordinary leather formulas: a. The main resin of translucent leather uses a resin with higher transparency; b. Translucent leather avoids inorganic crystalline additives as much as possible, and reduces the proportion and particle size of non-transparent additives to ensure uniform dispersion; c. The translucent leather has a thinner surface thickness, and at the same time, the foaming layer is uniformly reduced to reduce light absorption and scattering. From the above analysis, it can be seen that the key and difficult work of soft intelligent surface decoration with photoelectric display function lies in the development of high-transmittance translucent leather materials and the design, layout and production of high-quality and high-precision pattern layers.

[0060] The utility model arranges a preset pattern on the light-transmitting surface and illuminates the preset pattern through a backlight unit, thereby facilitating the display of the key pattern.
