Abstract

The present invention is a side rear lower member 20 having both sides of the elliptical protrusion 11 formed on the inner surface of the front pillar 10 formed on the inner side, and at the same time being vertically bent and having an elliptic curved surface 21 on the one side. Elliptical protrusions formed on both sides of the front pillar 10 by mounting the long square dash lower member 30 on the inside of the mounted side rear lower member 20 in accordance with the protrusion 11 of the front pillar 10. 11) The car's dash lower member which distributes the impact force generated in front of the vehicle, absorbs the impact force sufficiently to improve the safety of passengers in the room, and increases the rigidity of the vehicle, thereby improving the merchandise. And a coupling structure of side rear lower members.

Description

Combined structure of dash lower member and side rear lower member of car

The present invention relates to a coupling structure between the dash lower member and the side rear lower member of a vehicle. Since it is installed in the upper part of the member, it is possible to disperse the stress in the side impact of the vehicle and at the same time reduce the amount of impact transmitted to the passengers in the room.

In general, the tests to ensure the safety of passengers in the event of a car crash include FRONT IMPACT and SIDE IMPACT, which are important factors to ensure the safety of the car. It is used as a big item such as import regulation by legalizing safety value.

For example, North American legislation applies test conditions that vertically collide the vehicle vertically against the collision wall, while European legislation applies only a portion of the vehicle to the collision wall in the event of a frontal collision. It is common to see a big difference in applying test conditions that impinge frontal edges.

However, most of the automobiles currently produced have some safety values for forward collisions in North American regulations, but the safety values for forward collisions in European regulations are insufficient.

As shown in FIG. 1, the coupling structure between the dash lower member and the side rear lower member of the conventional vehicle is provided with the side rear lower member 2 and the side rear lower member at the same time. (2) The lower lower member 3 is connected to the inner end in a straight line.

The combined structure of the dash lower member (3) and the side rear lower member (2) of the vehicle configured as described above causes the front edge of the car to be collided by offsetting only a part of the vehicle to the collision wall during a frontal collision or by tilting the collision wall. When the test condition is applied, the load distribution acts only toward the side rear lower member (2), so it is easy to be damaged in the place where the dash lower member (3) and the side rear lower member (2) are combined, so that the impact force is not sufficiently absorbed. There was a problem that can not, and do not promote the safety of the passengers.

An object of the present invention is to distribute the impact force generated during the frontal collision of the vehicle, so that the impact force is sufficiently absorbed to promote the safety of passengers indoors, and the body rigidity is increased to improve the productability of the vehicle lower lower member and side rear lower To provide a member joining structure.

In order to achieve the above object, the present invention installs the side rear lower member on one side of the front pillar and at the same time extends the dash lower member to the front pillar area to install and combine the upper side rear lower member to distribute the stress during side collision of the vehicle. At the same time, the amount of impact transmitted to passengers in the room can be reduced as much as possible.

30: Dash Lower Member

As shown in FIG. 2, both sides are vertically bent at one side inside the front pillar 10 having the elliptical protrusion 11 formed on the inner surface thereof, and at the same time, the elliptic curved surface 21 is formed on the one side. The side rear lower member 20 is mounted to match the protrusion 11 of the front pillar 10, and the long square dash lower member 30 is mounted on the mounted side rear lower member 20 on the front pillar 10. It is characterized in that coupled to match the elliptical protrusions 11 formed on both sides inside.

The present invention configured as described above is fitted to the side rear lower member 20, the curved surface 21 of the front pillar 10 of the elliptical protrusion 11 of the elliptical part, and mounted on the side rear lower member 20 mounted above The long rectangular dash lower member 30 is coupled to the elliptical protrusions 11 formed on both sides of the front pillar 10 so as to disperse the impact force generated during the frontal collision of the vehicle and absorb the impact force sufficiently to prevent the passengers in the room. Promoting safety and increasing the body rigidity has the advantage of improving the productability.

As described above, in the present invention, the side rear lower member is installed at one side of the front pillar and at the same time, the dash lower member is extended to the front pillar to be installed and coupled to the upper side rear lower member. At the same time, since the impact amount transmitted to the passengers in the room is reduced as much as possible, there is an effect of improving the merchandise.

Claims (1)

On both sides of the front pillar 10, the elliptical protrusion 11 is formed on the inner surface of the front pillar 10, the vertical rear bent at the same time the outer side of the lower lower member 20 to form an elliptic curved surface 21 on the front pillar ( 10 and a long rectangular dash lower member 30 on the mounted side rear lower member 20 to the elliptical protrusion 11 formed on both sides of the front pillar 10. Coupling structure of the car dash lower member and side rear lower member, characterized in that the match is combined.
