Description

The automobile {A automobile}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile, and more particularly, to a vehicle equipped with a pedestrian airbag module that lifts a hood panel using a deploying force of an airbag cushion.

Generally, an engine room in which an engine and a radiator are disposed is formed in front of the automobile, and a hood panel for opening and closing the engine room is disposed above the engine.

The rear panel of the hood panel is hinged to the vehicle body so that the front panel is lifted up and down. However, when a pedestrian collided with a car, a pedestrian collapsed on the hood panel, and hit the head with the windshield, causing a secondary injury.

Therefore, in recent years, when a pedestrian collides with an automobile, an airbag cushion is deployed so as to cover the front of the windshield so as to perform a damping action, thereby preventing a pedestrian from being hit by a head on the windshield, The airbag module is installed in the vehicle.

The conventional pedestrian airbag module is disposed at the rear lower side of the hood panel. Therefore, the pedestrian airbag module is subject to the influence of the heat generated in the engine, and thus has a problem of adding a separate heat-insulating structure.

Further, when the pedestrian collides with the automobile, the hood lift disposed at the rear lower side of the hood panel lifts the rear of the hood panel. Since the hood lift lifts the rear lower side of the hood panel, the airbag cushion is deployed forward of the windshield through the gap. Therefore, a separate hood lift is required for deploying the airbag cushion to the windshield, and the hood lift raises the cost with expensive parts.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an automobile equipped with a pedestrian airbag module that raises the rear of a hood panel only by the deploying force of an airbag cushion without a separate operating part.

1 to 3, a vehicle 1 according to an embodiment of the present invention includes a body (not shown) for forming an appearance of the automobile 1, an engine 50 for generating power of the automobile 1, A hood panel 10 disposed on the upper side of the engine 50 to protect the engine 50, a windshield 20 disposed behind the hood panel 10, a windshield 20 and a hood panel 10, A cowl panel 30 disposed between the cowl tower 60 and the engine 50 and a pedestrian airbag module 100 installed above the cowl tower 60. The cowl 60 is disposed between the cowl 60 and the engine 50,

The vehicle body (not shown) creates a closed space, and various devices are arranged inside the vehicle body to accommodate the passenger and the cargo. It is also necessary to have a structure that can open and close a part of the vehicle to facilitate the entry and exit of passengers and cargo and maintenance of various devices. In addition, the body (not shown) protects passengers, cargo, and various devices from outside rain, wind, and dust. Since the vehicle body (not shown) forms an appearance, the shape of the vehicle body is the shape of the automobile 1 as it is.

An engine room in which a power generating device, a power transmitting device, and the like are disposed in front of a vehicle body (not shown) is formed. That is, in front of the vehicle body, an engine room that generally forms a well is formed, and an engine 50 and a transmission are disposed in the engine room. The vehicle body (not shown) is made of a steel material having good rigidity because heavy objects such as an engine 50, a transmission, and various ancillary equipment are mounted on the front of the vehicle body. In addition, when the vehicle body is subjected to a strong impact due to a frontal collision or the like, the vehicle body is damaged and absorbs the impact to prevent a strong force from being transmitted to the inside of the vehicle (1).

The hood panel 10 is disposed in front of the automobile 1. That is, in front of the vehicle body. The hood panel 10 is disposed on the upper side of the engine 50 and protects various devices such as the engine 50 and the transmission disposed in front of the vehicle body from the outside. Therefore, the hood panel 10 is formed by coupling the outer panel and the inner panel disposed below the outer panel. The outer panel of the hood panel 10 is preferably made of a material excellent in corrosion resistance because it is highly affected by external rain or wind and the inner panel of the hood panel 10 is highly affected by the heat of the engine 50 Is preferably made of a material having excellent heat resistance.

The hood panel 10 has a structure in which the front side is vertically raised and lowered. Therefore, the hood panel 10 is installed in front of the vehicle body so as to be able to open and close the engine room. In addition, when the pedestrian collides with the car 1 in front, the pedestrian collapses on the hood panel 10. Therefore, it is preferable that the hood panel 10 is made of an elastic material that absorbs shocks for protecting the pedestrian.

The windshield 20 is disposed behind the hood panel 10 to prevent rain, wind, etc. from entering the interior of the vehicle. The windshield 20 is made of a transparent material so as not to obstruct the view of the driver.

The engine 50 is disposed in the engine room formed in front of the vehicle body. The engine 50 generates power of the automobile 1, and a lot of heat is generated when the engine 50 is driven. The hood panel 10 is disposed on the upper side of the engine 50 and protected from external rain, wind, and the like.

The cowl panel (30) is disposed below the hood panel (10). The cowl panel 30 has a rigid structure of high strength in order to prevent the devices such as the engine 50, the transmission and the like from intruding into the vehicle body side during a front collision of the automobile 1. The cowl panel 30 is preferably formed in a shape that reduces the resistance of air

The cowl panel 30 is disposed between the cowl tower 60 and the engine 50 to reduce the heat generated in the engine 50 from affecting the pedestrian airbag module 100. [ That is, the cowl panel 30 prevents the pedestrian airbag module 100 from being deteriorated by the heat generated in the engine 50. The rear of the cowl panel (30) engages with the lower side of the cowl top (60).

The cowl tower (60) is disposed between the windshield (20) and the hood panel (10). The cowl tower (60) is provided with a pedestrian airbag module (100) on its upper side. Further, the cowl top cover 40 is disposed on the upper side of the cowl top 60 to minimize the influence of the outside. The cowl top (60) is coupled to the rear side of the cowl panel (30) on the lower side.

The cowl top cover 40 is disposed between the windshield 20 and the hood panel 10. A portion of the cowl top cover 40 is disposed on the rear side of the hood panel 10, and a cowl top 60 is disposed on the lower side.

The cowl top cover (40) is formed with a through hole (41) through which the pedestrian airbag module (100) penetrates. Therefore, the pedestrian airbag module 100 installed on the cowl tower 60 protrudes to the upper side of the cowl top cover 40. The through holes 41 may be formed corresponding to the left and right elongated pedestrian airbag module 100. The cowl top cover 40 is coupled to the upper side of the wiper and has an air inlet for introducing outside air into the room.

The pedestrian airbag module 100 includes a housing 130 forming an appearance, an inflator 120 generating a gas, and an airbag cushion 110 deployed when gas is introduced.

The pedestrian airbag module 100 is installed on the upper side of the cowl tower 60. A part of the upper part of the pedestrian airbag module 100 is disposed at the rear lower side of the hood panel 10 so that the airbag cushion 110 to be described later is deployed while lifting the rear lower side of the hood panel 10 when deployed.

The airbag cushion 110 and the inflator 120 are disposed inside the housing 130. Thus, the housing 130 forms a receiving space therein. The housing 130 is formed with a tier line 131 at an upper portion thereof where the airbag cushion 110 breaks when the airbag cushion 110 is deployed. Therefore, the airbag cushion 110 disposed inside the housing 130 can be easily deployed outside the housing 130. [0051] The tear line 131 is preferably formed on the edge of the windshield 20 side at the upper side of the housing 130 to guide the deployment of the airbag cushion 110 toward the windshield 20. [

The housing 130 is formed of TPO (Thermo Plastic Olefine) or TPE (ThermoPlastic Elastomer) material having good strength. Accordingly, the housing 130 can prevent the airbag cushion 110 from being scattered and broken when the airbag cushion 110 is broken along the tier line 131 when it is deployed.

The inflator 120 generates gas of high temperature and high pressure when the automobile 1 collides with a pedestrian in front. The inflator 120 is disposed inside the housing 130 and has a discharge port through which gas is discharged. The discharge port of the inflator 120 is connected to the airbag cushion 110 to supply gas to the airbag cushion 110.

The airbag cushion 110 is disposed inside the housing 130. The airbag cushion 110 is deployed toward the windshield 20 when the gas generated from the inflator 120 is inflowed. That is, the airbag cushion 110 is deployed toward the rear upper side. Accordingly, when the automobile 1 collides with the pedestrian in the frontal direction, the airbag cushion 110 protects the head of the pedestrian heading toward the windshield 20. The airbag cushion 110 is in contact with the head of a pedestrian, and is preferably made of a soft fabric material.

The airbag cushion 110 breaks the tear line 131 of the housing 130 by the deployment pressure and exits the housing 130 when the airbag cushion 110 is deployed toward the windshield 20. [ Further, the airbag cushion 110 lifts the rear lower side of the hood panel 10 when the gas is inflowed and expanded.

3 is a cross-sectional view of the automobile before the operation of the pedestrian airbag module according to the embodiment of the present invention. 4 is a cross-sectional view illustrating the operation of a pedestrian airbag module of an automobile according to an embodiment of the present invention. 5 is a perspective view showing the operation of the pedestrian airbag module of an automobile according to an embodiment of the present invention.

The operation of the automobile 1 according to the present invention will now be described with reference to FIGS. 3 to 5. FIG.

When the vehicle 1 collides with the pedestrian in front, the body of the pedestrian collapses on the hood panel 10, and the head of the pedestrian falls to the windshield 20. Thus, the hood panel 10 having elasticity primarily absorbs the impact with the pedestrian, thereby protecting the pedestrian.

Secondarily, when the automobile 1 collides with a pedestrian in front, the ACU provided inside the automobile 1 generates high-temperature, high-pressure gas from the inflator 120 of the pedestrian airbag module 100. The high-temperature, high-pressure gas flows into the interior of the airbag cushion 110, and the airbag cushion 110 is deployed toward the windshield 20 side.

The gas generated from the inflator 120 rapidly flows into the interior of the airbag cushion 110, so that the airbag cushion 110 has a large deployment pressure. The tear line 131 of the housing 130 is broken by the large deployment pressure of the airbag cushion 110 so that the airbag cushion 110 can be deployed outside the housing 130. [ The airbag cushion 110 is deployed by lifting the rear of the hood panel 10 by the deployment pressure of the airbag cushion 110.

The gas-filled airbag cushion 110 is disposed in front of the windshield 20 and is formed in a U-shape. Thus, the head of the pedestrian falls on the filled airbag cushion 110 and the pedestrian is protected.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It should be understood that various modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention.
