Description

Shock-absorbing structure of automotive side protection molding

The present invention relates to a shock absorbing structure of an automobile side protection molding. More specifically, the side protection molding installed on a side of an automobile is directly fixed to an outer panel of a vehicle, and an assembly of the vehicle body is provided with a shock absorbing leaf spring on one side. The present invention relates to a shock absorbing structure of an automobile side protection molding to improve the shock absorbing effect of a crash and side impact.

In general, side protection molding for automobiles is installed to protrude in a band form on predetermined portions of both sides of the vehicle to minimize the deformation and breakage of the side of the vehicle while absorbing the shock applied to the side of the vehicle in the event of a side contact of the vehicle. At the same time, it reduces the appearance of the side.

In the vehicle side protection molding, as shown in FIG. 4, after attaching the double-sided tape 11 to one side of the side protection molding (hereinafter, referred to as molding) 10, the double-sided tape ( 11) to bond the molding 10 to the side of the vehicle body or to form a fitting portion on one side of the molding, although not shown, and then formed in the outer panel of the vehicle body to form a hole that can be combined with the fitting hole The joint is fixed to the side of the vehicle body.

However, as described above, when the molding installed on the side of the vehicle penetrates the double-sided tape with rainwater or other impurities, the adhesive strength of the double-sided tape is degraded or killed, and the molding is frequently dropped, resulting in poor appearance. However, there are problems such as failure to effectively perform the role of side protection.

Therefore, in order to solve the problems described above, the molding is directly fixed to the outer panel of the side of the vehicle body, and fixed, but provided with a shock absorbing plate spring on one side of the molding, and supported by a plate installed inside the outer panel It is an object of the present invention to strengthen the assembly and fixing state with the vehicle body, and to improve the cushioning effect during side impact.

In order to achieve the above object, the present invention provides a molding 10 attached to the side outer panel 1 of the vehicle body by using a double-sided tape 11, and is formed at a predetermined portion of the outer panel 1 and is molded ( The coupling hole 2 and the coupling groove 21 formed at the upper and lower portions of the molding 20 and the buffer and plate springs 22 and the molding 20 installed at one side of the molding 20 are respectively coupled to the coupling hole 2 and 20. Supporting the leaf spring 22, characterized in that the outer panel (1) is composed of a diaphragm (30) spaced apart a predetermined interval.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

Figure 2 is an exploded cross-sectional view of the present invention, 21 is a coupling groove, 22 is a leaf spring.

As shown, the leaf spring 22 formed on one side of the molding 20 has a hemispherical curved surface so that the upper and lower portions are unfolded during the side impact of the vehicle and absorbs and cushions the impact during the collision.

The upper and lower coupling grooves 21 of the molding 20 are formed to be fitted into the outer panel 1, the coupling hole 2 up and down, respectively.

The length before and after the coupling hole 2 of the outer panel 1 is equal to the length of the molding 20 so that the molding 20 is coupled to the entire coupling hole 2.

Referring to the operation of the present invention as described above are as follows.

The coupling groove 21 of the molding 20 is coupled to the upper and lower ends of the coupling hole 2 formed in the vehicle body side outer panel 1 to fix the molding 20 to the outer panel 1.

At this time, the diaphragm 1 installed inwardly of the outer panel 10 is supported by a shock absorbing leaf spring 22 provided on one side of the molding 20, and the leaf spring 22 is bent in a hemispherical shape to be impacted upon side impact. Will be buffered.

As described above, when the impact is applied to the molding during a side collision of the vehicle, the molding 20 is deformed toward the inner panel. At this time, one side of the molding 20, that is, the leaf spring supported by the diaphragm 30 on the inner panel side 22. ) Is provided so that the leaf spring 22 instantly absorbs and cushions the shock.

After coupling the upper and lower portions of the coupling hole 2 of the outer panel 1 to the coupling groove 21 of the molding 20, sealing treatment is performed for waterproofing and rust prevention.

As the cushioning structure of the vehicle side protection molding of the present invention as described above, the molding is directly coupled to the side of the vehicle body, so that no separate parts are required according to the fixing, thereby reducing the number of parts and improving the assemblability and securing the fixed state. This prevents the molding from deviating from the side of the vehicle body, while effectively absorbing and buffering the impact during the side collision of the vehicle, thereby minimizing the deformation and breakage of the side of the vehicle and at the same time protecting the occupants in the cabin. have.
