Claims (9)

  1. A steering wheel cover provided in the center of the steering wheel, having a tear line formed by internal pressure, and covering the steering wheel airbag; A light source module installed on the inner surface of the steering wheel cover and emitting light toward the outer side of the steering wheel cover; and A wire provided on the inner side of the steering wheel cover to supply power to the light source module, arranged in a direction intersecting the tearline of the steering wheel cover, and cut when the steering wheel airbag deploys; A melting module that connects the end of a wire to a light source module and melts due to overvoltage when overvoltage is applied to the wire; and A steering device characterized by including an overvoltage generating device connected to a wire to generate overvoltage and operate a melting module.
  2. In claim 1, A steering device characterized in that the steering wheel cover includes an upper cover and a lower cover, the tearline connects the upper and lower parts and extends in the left and right directions of the steering wheel, and when the steering wheel airbag deploys, the tearline is cut and the upper cover and the lower cover are opened.
  3. In claim 2, A steering device characterized by a light source module installed on the inner side of an upper cover, and a wire arranged to extend toward a lower cover while intersecting a tear line in a state connected to the light source module.
  4. In claim 2, A first hinge portion at the upper part of the upper cover that connects the upper cover and the steering wheel to rotate the upper cover; and A steering device characterized by further including a second hinge portion at the lower part of the lower cover that connects the lower cover and the steering wheel to rotate the lower cover.
  5. delete
  6. In claim 1, The steering wheel airbag deploys by the operation of the inflator, and A steering device characterized by an overvoltage generator that operates by receiving an operating signal from an inflator.
  7. In claim 1, A steering device characterized by a light source module that emits light to the outside of the steering wheel cover to illuminate the vehicle's emblem.
  8. In the airbag deployment method of the steering device of claim 1, A step in which a collision signal is input from a vehicle's collision detection sensor to an inflator; A step in which gas is injected into the steering wheel airbag when a collision signal is input to the inflator; A step in which a wire connecting a light source module, positioned across a tear line formed on the steering wheel cover due to the deployment pressure of the steering wheel airbag, is cut and the tear line is cut so that the steering wheel cover is opened; and A method for deploying an airbag of a steering device, characterized by further including the step of disabling the connection between the wire and the light source module by applying an overvoltage to a welding module connecting the wire and the lighting device after the step in which a collision signal is input.

Description

Steering apparatus and airbag deployment method of the steering apparatus The present invention relates to a steering device and a method for deploying an airbag of a steering device. Airbag systems are commonly used in vehicles, particularly in the steering wheel. These airbags are designed to inflate during an accident to protect occupants from harmful impacts with the steering wheel during a collision. Therefore, airbag systems are typically installed in the steering wheel. It is also known that many vehicle manufacturers want to display their logos or trademarks on the steering wheel. These logos or trademarks are often colored images and are placed on the steering wheel (such as on the steering wheel cover used to conceal the airbag system). Some logos may feature metallic chrome accents to enhance the appearance. The placement of such logos promotes brand recognition and helps vehicle occupants remember that the car manufactured by that company is safe because it is equipped with airbags. In order to make the manufacturer's logo stand out more, some groups began looking for ways to highlight that logo/trademark. However, until now, there has been no acceptable method to illuminate not only chrome/metallic parts but also the colored parts of the trademark, and when a lighting device was installed on the driver's airbag, there was a problem where the lighting device would be damaged as the airbag deployed. The matters described above as background technology are intended only to enhance understanding of the background of the present invention and should not be construed as an acknowledgment that they constitute prior art already known to those skilled in the art. FIG. 1 is a perspective view illustrating a light source module and a wire of a steering wheel lighting device according to one embodiment of the present invention. FIG. 2 is a drawing showing the rear view of a steering wheel lighting device according to an embodiment of the present invention. FIG. 3 is a side cross-sectional view illustrating the process of operation when a steering wheel airbag is deployed in a steering wheel lighting device according to an embodiment of the present invention. FIG. 4 is a flowchart of a method for deploying a steering wheel lighting device according to an embodiment of the present invention. Specific structural or functional descriptions of the embodiments of the present invention disclosed in this specification or application are merely illustrative for the purpose of explaining embodiments according to the present invention, and embodiments according to the present invention may be implemented in various forms and should not be interpreted as being limited to the embodiments described in this specification or application. Since embodiments according to the present invention may be subject to various modifications and may take various forms, specific embodiments are illustrated in the drawings and described in detail in this specification or application. However, this is not intended to limit embodiments according to the concept of the present invention to specific disclosed forms, and it should be understood that it includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the present invention. Terms such as "first" and/or "second" may be used to describe various components, but said components should not be limited by said terms. For the sole purpose of distinguishing one component from another, for example, without departing from the scope of rights according to the concept of the present invention, the first component may be named the second component, and similarly, the second component may be named the first component. When it is stated that one component is "connected" or "connected" to another component, it should be understood that while it may be directly connected or connected to that other component, there may also be other components in between. Conversely, when it is stated that one component is "directly connected" or "directly connected" to another component, it should be understood that there are no other components in between. Other expressions describing the relationship between components, such as "between" and "exactly between," or "adjacent to" and "directly adjacent to," should be interpreted in the same way. The terms used herein are used merely to describe specific embodiments and are not intended to limit the invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this specification, terms such as “comprising” or “having” are intended to specify the existence of the implemented features, numbers, steps, actions, components, parts, or combinations thereof, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.
