Abstract

The present invention relates to a horn operation structure used without an airbag on the drivers seat. A conventional horn operation structure has a complex structure when there is no airbag on the drivers seat, thereby increasing the component development period and product cost while increasing the weight due to a large number of metal components being used. According to the present invention, the horn operation structure used when there is no airbag on the drivers seat or the steering wheel of a vehicle to operate the hole includes: a steering wheel assembly (100) which is arranged on the front surface of the drivers seat to let a driver adjust the vehicle direction, includes a horn cover installation unit (110) in the center, and forms multiple steering wheel horn contact points (150) in all four directions from the horn cover installation unit (110); a horn housing (200) which is installed on the horn cover installation unit (110) of the steering wheel assembly (100) to move up and down, has a horn cover insert form installation unit (210) formed on the center, and includes a horn contact point plate (300) having multiple horn contact points (350) and elastic spring holding protrusions (220) on the lower part; a horn cover (400) including a horn housing installation unit (410) formed on the lower center to be fitted from the upper part of the horn housing (200) and be fixed and coupled thereon; and elastic springs (500) installed between the elastic spring holding protrusions (220) formed on the lower part of the horn housing (200) and the lower part of the horn cover installation unit (110) formed on the steering wheel assembly (100).

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a horn-

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horn operation structure in the absence of a driver's seat airbag, and more particularly, to a horn operation structure for operating a horn when an airbag is not provided in an automotive steering wheel, The present invention relates to a horn structure in the absence of a driver's seat airbag in which an airbag seat is filled with a plastic material so as to enable parts to be compatible without separately producing a horn system of a vehicle without an airbag.

Generally, the horn type of a car is largely divided into a fixed type and a fluid type.

Fixed type is a type that does not move because the horn cover is fixed. It is the principle that the horn works when the operator presses the horn cover with the palm of the hand and the horn plate meets the contact point.

In other words, the horn cover and the intermediate plate are attached to the back of the horn cover. When the driver presses the horn cover, the horn cover made of the soft PVC material is deformed downward and the ABS material The intermediate plate to be formed is pushed downward.

As a result, the contacts on the horn plate contact each other by the rib (RIB) protruding downward from the intermediate plate, so that the horn is operated.

The other type is a floating type. When the driver's seat airbag is installed as standard, the airbag cushion is inserted under the airbag cover and the retainer ring and the inflator are formed under the airbag cushion. The horn type can not be used, so that when the driver presses the airbag cover by applying the floating type, the airbag cover is tilted in the direction in which the horn is pressed, thereby operating the horn.

However, the horn operation structure in the absence of a conventional driver's seat airbag has a complicated structure, resulting in an increase in the component development period, an increase in the product unit price, and an increase in weight due to a large number of metal parts.

In addition, when the driver presses the horn cover during the operation of the horn, the horn cover is deformed downward, and the horn contact is brought into contact with the horn plate so that the horn is operated. There was also a problem.

Especially, in winter, the plastic property of the horn cover is frozen, and when the driver presses the horn cover, the horn cover does not fall sufficiently downward, resulting in a failure of the horn operation. There was also a problem.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a steering wheel assembly in which an airbag is not provided in a driver's seat so that parts can be compatible without separately producing a horn system of a vehicle without an airbag, The complicated horn operation structure in the absence of the conventional driver's seat airbag increases the period of component development, increases the product cost, increases the weight due to many metal parts, When the horn cover is pressed down, the horn cover is deformed to the lower side and the horn contact is brought into contact with the horn plate, so that the horn is not operated properly if the quality of the horn cover is scattered. When the driver presses the horn cover, the horn cover To provide a horn operating structure if enough if you do go down to the bottom even occur without the driver's seat by allowing one run lead to results should not the soul works, it can seriously effectively solve the problems that dangerous situations can come airbags.

In the horn operation structure for operating the horn when the airbag is not provided on the steering wheel of the automobile, the driver is provided on the front of the driver's seat to adjust the direction of the vehicle, A steering wheel assembly having a plurality of steering wheel horn contact points formed on four sides of the horn cover mounting portion and a horn cover mounting portion of the steering wheel assembly so as to be vertically movable and having a horn cover insertion foam mounting portion formed at the center thereof, A horn cover having a horn spring fixing protrusion and a horn contact plate having a plurality of horn contact points formed therein; a horn cover having a horn housing mounting portion formed at an upper center of the horn housing to be fixedly engaged with the upper portion of the horn housing; A spring-loaded spring formed on the lower portion of the cover mounting portion and the lower portion of the horn housing And a elastic spring provided between the projections.

When the driver presses the upper part of the horn cover, the driver's pressing pressure is transmitted to the horn housing as it is, and the horn cover insertion foam, Shaped horn cover insertion foam fixing groove is formed in a lower portion of a horn cover insertion foam formed of a foam foam of a plastic material in the horn cover insertion foam mounting portion of the horn housing, And a horn cover insertion foam fixing protrusion that is fitted and fixed to the horn cover insertion foam fixing groove at a position corresponding to the cover insertion foam fixing groove so that the horn cover insertion foam and the horn housing can be firmly fixedly coupled. It is possible to achieve the purpose.

According to the present invention, in the horn structure for operating the horn when the airbag is not provided on the steering wheel of the automobile, a plastic material foam is filled in the airbag seat of the steering wheel assembly having the conventional airbag, It is possible to make the parts compatible without producing the horn system of the vehicle separately.

And, by using the parts of the vehicle with the airbag in a compatible manner without producing the horn system of the vehicle without the airbag separately, the structure of the horn operation is simplified, thereby reducing the development period of the parts and lowering the product cost.

In addition, since the plastic foam is filled in the space where the airbag space is installed in the horn, if the driver presses the horn cover during the operation of the horn, if the horn cover is deformed downward, There is also an effect of preventing the phenomenon of becoming.
