KR-102961710-B1 - VEHICLE HEADLINER CONNECTED TO AUDIO SYSTEM

Abstract

The present invention configures a headliner having various functions to be controlled in conjunction with a vehicle's audio system, thereby not only adding additional functions to the headliner but also enabling a differentiated headliner equipped with complex functions. In particular, by configuring the audio system to be controlled using voice, screen touch, or manual operation, the present invention allows the driver and passengers inside the vehicle to conveniently control the audio system regardless of their location. Furthermore, the present invention manufactures the headliner as a single unit by sequentially laminating a polyurethane foam sheet, an acoustic panel sheet, and a fabric made of polyester fibers, thereby further improving the acoustic effect through a layered structure with excellent acoustic properties.

Description

Vehicle Headliner Connected to Audio System The present invention relates to a headliner for an automobile connected to an acoustic system, and more specifically, by configuring the headliner to be connected to and controlled by an audio system installed in the automobile through an acoustic detection sensor, a touch control sensor, and an acoustic control module, the effect of the acoustic system can be obtained through the headliner. In this case, the headliner is manufactured by sequentially laminating a polyurethane foam sheet, an acoustic panel sheet, and a fabric made of polyester fibers, thereby enhancing the noise blocking and absorption effects and improving the acoustic effect. Generally, a car headliner is a material mounted facing the roof panel inside the vehicle to cover the interior ceiling, and it is typically made of multi-layered composite materials. These headliners serve not only an aesthetic purpose but also various functional roles. For instance, they are designed to create a clean and luxurious feel inside the vehicle or are manufactured to harmonize with the interior using various colors and materials. They also provide a quiet environment by reducing noise entering the cabin and absorbing internal noise, and help regulate the vehicle's interior temperature by blocking external temperatures. Meanwhile, in addition to the basic functions of a headliner, various additional functions may be configured in such headliners, as shown in (Patent Document 1) to (Patent Document 3) below. (Patent Document 1) Korean Registered Patent No. 10-1588630 The present invention aims to provide a headlining for an automobile with a heat-blocking function and a method for manufacturing the same, wherein a heat-blocking layer is stacked to form an integral structure using a polyurethane foam sheet with excellent thermal insulation effect to produce a heat-blocking effect, thereby blocking heat transfer into the interior of the automobile through the roof panel, which occupies a large portion of the exterior exposed to the automobile, thus creating a cool and comfortable interior environment even in midsummer, and in particular, suppressing the rise in interior temperature to reduce the operating time of the air conditioner, thereby improving fuel efficiency. In particular, another objective of the present invention is to provide a headlining for an automobile with a heat-blocking function and a method for manufacturing the same, wherein a heat-blocking material is coated onto a hot-melt film to substantially produce a heat-blocking effect, thereby enhancing the heat blocking effect transmitted through the roof panel while minimizing the increase in the overall weight of the automobile, so that the effect of improving fuel efficiency along with the heat-blocking function can be expected. Furthermore, another objective of the present invention is to provide an automotive headlining having a heat-blocking function and a method for manufacturing the same, which utilizes carbon nanotubes (CNT) as a heat-blocking material to minimize weight increase while enhancing the heat-blocking effect. (Patent Document 2) Korean Published Patent No. 10-2024-0040220 The present invention provides a headliner comprising a substrate configured to face a roof panel and a fabric layer installed on the surface of the substrate exposed to the interior of the vehicle, wherein sound generated from a speaker installed on the substrate is configured to pass through a through hole formed in the substrate and directly transmit through the fabric layer, thereby eliminating the need to use a separate configuration such as a speaker grille for sound treatment on the fabric layer, thus enhancing the aesthetic sense and appearance of the vehicle interior while allowing the speaker to be used easily and conveniently. In particular, the present invention provides a headliner for a vehicle equipped with a speaker that further enhances the sound effect by using a breathable fabric for the fabric layer through which the sound generated from the speaker transmits, thereby allowing the sound to easily pass through the fabric layer and spread into the vehicle interior. (Patent Document 3) Korean Published Patent No. 10-2019-0033722 The present invention relates to a headliner comprising a substrate and a surface layer, wherein multiple vent holes are formed in the substrate and a breathable surface layer is utilized, thereby enabling the fluid injection function to be performed without using a separate air vent grille. In particular, the present invention can create a comfortable indoor environment without causing discomfort even if the fluid passing through the vent holes and the breathable surface layer is directly ejected toward the driver or passenger. Furthermore, the present invention performs the same function as a conventional air vent grille, but since the component performing this function is not exposed within the vehicle's interior, it
