Abstract

PURPOSE:To prevent deformation and damage of parts or the like around a bumper, by fixing a facer stay directly to a car body further decreasing size of upper and bottom end parts of a bumper reinforcer not to be adapted to a bumper facer at light collision. CONSTITUTION:A stay member 21 of a bumper facer stay 20 is connected to a radiator core support P of a car body. While upper and bottom end parts of a bumper facer 4 are secured to a connection member 23 of the facer stay 20. On the other hand, upper and bottom faces 2a, 2b of a bumper reinforcer 2 are formed to short size not to be adapted to upper and bottom face parts 4a, 4b of the bumper facer 4 even if said faces 2a, 2b are deformed to an open mouth shape at the time of light collision. Accordingly, at light collision whe the bumper facer 4 is deformed to an open mouth shape, a car body part of radiator grill 6 or the like arranged around a front bumper B and a car body 7 can be prevented from deformation and damage.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a member structure, and in particular, to prevent interference with repair parts such as a radiator grill installed on the bumper and the vehicle body due to deformation of the bumper during a light collision. The present invention relates to a bread pastry that can effectively prevent r.

As conventional member structures, those shown in FIG. 1 and those shown in FIG. 2 are known.

The former damper structure consists of a pair of left and right panpasties 1 whose rear ends are connected to strength members such as side members through bolts and nuts, and a C-channel shape in which m is attached to the tip of the panpasties 1. Member Reinforce 2 and I#1llllK before this member Reinforce 2:
It is composed of a space 3 and a bread puffer 4 arranged to surround the spacer 3 and the reinforcement 2. Upper eyes [These are fixed to the upper and lower ends of Shibamba Reinforce 2.

In addition, the latter value of Bambana/a is obtained by using a shock absorbing member 10 instead of the Pampasti of the member mounting member t-gb i, and a back plate 11 at the tip of the shock absorber 10. The member reinforcement 2 is arranged and fixed through the member reinforcement 2, and a spacer 3f is interposed between the member reinforcement 2 and the bread buffer 4, and a spacer 3f is interposed between the member reinforcement 2 and the bread buffer 4.
The end portion is fixed to the upper part of the member reinforcement 2 by a bolt nut 5.

However, in the conventional member structure such as
In either of the two structures, the member reinforcement 4 and the member reinforcement 2 are integrally connected via the bolt nut 51, so that due to the deformation of the fascia q during a light collision, We have fixed the problem that the upper/F side of the member reinforcement 2 is deformed and becomes open, causing interference with repair parts such as the radiator grille 6 arranged around the member and the vehicle body cross member 1, which can easily cause damage. f
However, in the case of the latter structure, in order to particularly improve the rigidity of the member reinforcement 2, the member reinforcement 2 and the backplate 11 form a closed cross-section structure, or the reinforcement 2 itself is made thick. It also had disadvantages such as increased weight.

The present invention has been devised in view of the above-mentioned dust condition, and its purpose is to prevent the member V-inforce from opening due to the load in the event of a light collision, causing the member such as the radiator grill to rotate 9 times. The objective is to provide a member #I that can effectively prevent damage due to interference with parts and the vehicle body.

In order to achieve such an object, this invention V is composed of a member reinforcement formed by 1M attached to the tip yii of the panpasty, and a bread baffle force disposed so as to cover this member reinforcement. The upper and lower ends of the member's pan-buff reinforcement are solidified in the flywheel, and this fuser is placed directly on the heavy object. It is formed to have a short size so as not to come into contact with the upper F surface of the Eisha.

Next, based on the embodiment shown in FIG.
-Explain to Tougetsu I.

The bag structure according to the embodiment shown in FIGS. 3 and 4 shows an Ml embodiment in which all front members BK of the present invention are applied, and this front member B is molded from an elastic body such as polycarbonate. Pair of left and right panbasti 1

It is composed of a spacer 3 made of Nikam, a C-channel autumn pan baffle 4 that is attached to cover the spacer 3, and a fascia stay 20 that supports the pan buff 7 and 4. ing.

As shown in FIG. 4, this face lift 20 consists of a pair of left and right C-shaped stay members 21.21, and a connecting member 22. 23, and the stay part @21.21 is made up of a bolt nut 2 as shown in FIG.
4 to the radiator core support P of the vehicle body, and the upper and lower ends of the pan-pan eisha 4 are simultaneously attached to the connecting members 22 and 23 through bolts 25 and 25, respectively.

h, the upper dowels 2a and 2b of the member reinforcement 2 are I4! ! Opposition 2] On the moon fη, a 10-shaped deformed site, upper and lower lIIIm 4 a of Pambahueisha 4.

In the member structure according to this embodiment, the member structure 4 is shaped to have a shorter dimension than the 1-6 collision. Since it is fixed to Noe f Sea Yasty 2υ which is not involved in the shape, Panba Faye Sha 4 is deformed into an open mouth shape) and is placed in Atomenpa B times 9 1. In addition to preventing accidents such as deformation and damage of vehicle body parts such as the radiator grille 6 and heavy objects that have been damaged, the Panpasty 1 is molded with an elastic material and has the same level of absorption performance as a shock-absorbing panpa. Therefore, it is possible to obtain a member that is lighter and lower in weight than a shock absorbing member.

Figure 8g5 shows the second embodiment of the present invention, and the member structure according to this example is
The lip 12 protruding from the back side is fixed with a clip 13 on the back side of the bumper reinforcement 2, and the space 3 is attached to the member reinforcement 2 via the clamp rough 14.
By fixing it to the upper surface 2a, the deformation of the Menpa Reinforce 2 is transmitted to the front surface of the Pampan Aisha 4,
Other than making it easy to determine whether there is any deformation of the member or whether parent replacement is necessary, the other configurations and functions are completely the same as in the first embodiment, so the same reference numerals as in the first embodiment are used in the drawings. The detailed explanation will be omitted here.

Although the above embodiments have been described taking as an example the case where the invention is applied to Jin's invention t70 Ntobamba B, it goes without saying that the present invention can also be applied to Lyapamba.

Since the present invention includes the above configuration, it is possible to effectively prevent the deformation of the vehicle body parts and the vehicle body due to member deformation during a light collision.
