Abstract

The present invention provides a shock absorbing west molding mounting structure that can directly reduce the number of processes and stiffness during side impact by directly fastening the side impact bar and the west molding formed on the automobile door, thereby achieving passenger safety. In the known west molding mounting structure, the position of the side impact bar 2 and the plastic west molding 5 coincide with both sides of the door outer panel 3 so that the first member 7 is made of steel. A side impact bar (2) by filling a thermoplastic or cement filler (9) between the first and second members (8) and a plastic waist molding (5) attached to the outside and penetrating the inside thereof. ) And the nut (11).

Therefore, according to this proposal, it is possible to increase the rigidity of the door by adding the function of the west molding used as a simple decoration effect of the existing. By eliminating the sealer used when installing the existing side impact bar, the number of processes and material can be reduced. It is a practical design that expects the NVH reduction effect due to the dispersion of the natural frequency even when driving because the thermo plastic or cement absorbs the impact force during side impact.

Description

Shock Absorbing West Molding Mounting Structure

The present invention relates to a shock absorbing west molding mounting structure. In particular, the side impact bar and the west line molding are directly connected to both sides of the door outer panel by bolts, which are directly tightened with nuts. The present invention relates to a shock absorbing west molding mounting structure capable of achieving safety.

Generally, the west molding of a car is made of metal or resin and is formed in a strip shape along the west line of the car to protect and decorate the car body.

As shown in FIG. 2, the west molding mounting structure includes a plastic side molding formed by a mounting clip along a west line horizontally formed on a door outer panel, and a side impact bar mounted on a surface of the door inner panel. The sealer is arranged between the panels.

However, since the above-mentioned west molding is simply mounted on the surface of the door outer panel by a mounting clip, besides serving as a side protection and decoration of the vehicle body, the shock absorbing and rigidity is weak, so that the impact can not be effectively absorbed during side impact, resulting in high human injury. There was a problem.

The present invention has been made in view of the above problems, and by directly coupling the side impact bar and west molding, it provides a shock absorbing west molding mounting structure that can reduce the number of processes and maximize the rigidity during side impact to promote passenger safety. It is a task to do it.

If described in detail by the accompanying drawings the configuration and operation / effect of the present invention for achieving the above object is as follows.

A sealer 4 is disposed between the side impact bar 2 mounted on the ordinary door inner panel 1 and the door outer panel 3, and a waist line horizontally formed on the door outer panel 3 is provided. In the known west molding mounting structure in which the plastic west molding 5 is mounted by a plurality of mounting clips 6,

Align the position of the side impact bar 2 and the plastic west molding 5 so as to be in contact with both side surfaces of the door outer panel 3, and between the first steel member 7 and the second member 8 The side impact bar (2) and the nut (11) are fastened using a bolt (10) which fills the plastic or cement filler (9) and which the plastic west molding (5) is attached to the outside and penetrates the inside. will be.

According to the above configuration, the side impact bar 2 and the waist molding 5 having the structure described above are fastened by the nut 11 by penetrating the bolts 10 on both sides of the door outer panel 3 so as to be assembled. In addition to reducing the number, the rigidity of the door is increased to effectively absorb the impact during side impact to suppress the inflow of the door.

As described above, according to the present proposal, it is possible to increase the rigidity of the door by adding a function of the west molding used as a simple decoration effect.

By eliminating the sealer used when installing the existing side impact bar, the number of processes and material can be reduced.

It is a practical design that expects the NVH reduction effect due to the dispersion of the natural frequency even when driving because the thermo plastic or cement absorbs the impact force during side impact.
