Description

Technical Field

[0001] This application relates to the technical field of instrument manufacturing, and specifically, to an automotive interior surface. Background Art

[0002] Intelligence is the main theme of the development of the current automotive industry. Consumers are no longer limited to the demand for beautiful automotive exterior designs and are increasingly fond of intelligent surface decoration designs that integrate functionality and decoration.

[0003] In recent years, more and more concept vehicles of major automakers have been displayed at domestic and international auto shows, demonstrating designers' concepts for future automotive interior cockpits. Future automotive interior cockpits will develop in the direction of intelligence, especially in aspects such as the overall visual, tactile, and interaction feedback of the interior. Interior design will shift from traditional decoration to intelligent decorative surfaces that combine decoration and function. In addition to the texture, touch, and formability of traditional decorative materials, intelligent decorative surfaces can also simultaneously possess human-machine interaction functions such as optoelectronic dynamic display, touch control, and voice control, which is a highly integrated decoration technology. Combining the light-transmitting property and decorative property of materials is the prerequisite for realizing intelligent decoration. Therefore, the development of interior intelligent surface decoration technology can be divided into three stages.

[0004] The first stage realizes the integration of light-transmitting hard decorative materials (such as light-transmitting INS, light-transmitting IML, light-transmitting TOM, etc.) and functions such as optoelectronic display with control logic (such as light source breathing lighting, in-mold decoration film with flowing water effect, real wood decoration, etc.).

[0005] The second stage realizes the integration of soft light-transmitting decorative materials and optoelectronic display functions with control logic (such as light-transmitting leather, light-transmitting fabric, etc.).

[0006] The third stage realizes the multi-functional integration of decorative material optoelectronic display, intelligent control (such as gesture control, intelligent touch, voice control, etc.).

[0007] Decoration technologies that combine traditional decoration with optoelectronic display functions have been applied. It is mainly achieved by combining the in-mold insert technology (INS) with the panel backlight atmosphere lamp technology. This technology is relatively mature and has a large degree of design freedom in part design, which can meet the requirements of small internal space, large curved surfaces, and even unique appearance effects of interior parts products. Its application in vehicle interior decoration is also increasing. Currently, instrument panel decoration parts of models such as Geely Boyue GE and Venucia Star have started to use such intelligent surface decoration parts. This decoration solution needs to be completed by the cooperation of INS film manufacturers and part manufacturers - the film manufacturers are responsible for film production, and the part manufacturers are responsible for processing the film into formed parts. The film needs to pre-form the decoration pattern on the transparent carrier film through methods such as roller printing ink and vacuum evaporation plating, and then thermocompound the film with the decoration pattern and the ABS substrate to obtain the INS original film. Part forming requires first thermoforming and three-dimensional punching of the original film into the part shape in the mold, and then injection molding the product after the film is fully cooled.

[0008] There is relatively little research on how to combine soft light-transmitting film with electronic printing to achieve intelligent touch at present, which is also a technical difficulty to be overcome at present. It is necessary to explore a reasonable flexible transparent conductive coating and production process to achieve the organic combination of transparent touch capacitors and light-transmitting leather. How to achieve seamless and precise positioning of transparent capacitors and pattern display layers, circuit durability, and heat dissipation are all technical problem points to be solved in the future. When the light-transmitting material is given the performance of an integrated circuit and is supplemented with various optoelectronic displays, sound control, gesture control, and touch sensors, the realization of advanced human-machine interaction functions will no longer be a dream.
