Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a side member installed in a vehicle.

(Prior art and its problems) As shown in Fig. 3, two rear floor side members 2, 2 are usually arranged in parallel under a floor panel (not shown) at the rear of the vehicle 1. There is.

FIG. 4 shows a rear perspective view of the conventional rear floor side member 2. As shown in the figure, the side member main body 3 of the rear floor side member 2 has a substantially U-shape such as a hat-like cross section, and floor panel mounting pieces 3a, 3 are attached to the upper part along the longitudinal direction of the member.
a is provided, and a back panel attachment piece 3b is provided at the rear end. Further, a reinforcement 4 is installed inside the U-shaped groove 3c of the side member main body 3 along its inner peripheral surface.

By the way, this rear floor side member 2 is
Due to a mistake in the manufacturing process, the reinforcement 4 may not be installed. Therefore, an identification hole 5 is formed on the bottom surface 3d of the side member 3, and the automatic identification device passes through the identification hole 5. The presence or absence of Reinforcement 4 was identified. However, by forming the identification hole 5, the strength of the side member 2 is reduced, and water, mud, etc. may enter through the identification hole 5 when the vehicle is running after the side member 2 is assembled to the vehicle, and the identification There was a problem that rust occurred in the area around the hole 5.

(Purpose of the invention) The object of this invention is to solve the above-mentioned problems of the prior art, and to provide a side member that does not cause a decrease in strength or the occurrence of rust, and in which the presence or absence of reinforcement can be identified by an automatic identification device. With the goal.

(Means for Achieving the Object) This invention is a side member in which a reinforcement is installed in a U-shaped groove of a side member main body having a substantially U-shaped cross section, and in order to achieve the above object, An identification protrusion protruding outward from the end of the side member main body is provided at the end of the reinforcement.

(Embodiment) FIG. 1 is a perspective view showing the rear part of a rear floor side member which is an embodiment of this invention. As shown in the figure, in this side member 6, a reinforcement 8 having a U-shaped cross section is installed in a U-shaped groove 7c of a substantially U-shaped side member main body 7. The side member main body 7 has floor panel mounting pieces 7a, 7a protruding outward from the upper ends of both side walls, and a back panel mounting piece 7b protruding outward from the rear end thereof. There is. On the other hand, at the rear end of the reinforcement 8, an identifying protrusion 9 is integrally provided so as to protrude rearward from the back panel attachment piece 7b of the side member main body 7. This identification protrusion 9 is the side member main body 7.
The groove 7c is provided along a corner formed by the bottom surface and one inner surface of the U-shaped groove 7c.

According to this side member 6, since the identification protrusion 9 of the reinforcement 8 protrudes rearward from the rear end of the side member main body 7, the presence or absence of the reinforcement can of course be confirmed visually. It is also possible to determine whether the reinforcement 8 is attached or not by detecting the presence or absence of the identification protrusion 9 using an automatic identification device. Therefore, unlike the conventional rear floor side member 2 shown in FIG. 4, there is no need to form an identification hole 5, and a decrease in the strength of the side member 6 is prevented, and water, mud, etc. This prevents the infiltration of rust and prevents the formation of rust.

Further, according to this side member 6, when assembled, the lower back panel 10 is attached to the back panel attachment piece 7b of the side member main body 7, as shown in FIG.
When installing the reinforcement 8, insert the reinforcement 8 into the inner peripheral edge of the bumper mounting hole 10a of the lower back panel 10.
By locking the identifying protrusion 9, the lower back panel 10 can be easily positioned in the vertical direction and in the vehicle width direction. In addition, in the same figure, 11
12 is a cross member attached to the rear surface of the lower back panel 10, and 12 is a floor panel to which the floor panel attachment pieces 7a, 7a of the side member main body 7 are attached.

(Effect of the invention) As described above, according to the side member of this invention, since the end of the reinforcement is provided with the identification protrusion protruding outward from the end of the side member main body, the identification The presence or absence of reinforcement can be identified by an automatic identification device using the protrusion, and there is no need to form an identification hole in the side member body, which has the effect of maintaining sufficient strength and preventing the occurrence of rust. is obtained.
