Description

[Detailed explanation of the idea] The present invention relates to improvements in hook members for automobiles.

Conventionally, as shown in FIG. 1, a hook member 6 for connecting a towing rope or the like has been fixed to a longitudinal frame 4 of a car body 2 of an automobile, but the hook member 6 is generally not suitable for heavy loads. Many have been put into practical use that are formed with sufficient strength to withstand durability, have a sufficient span in the longitudinal direction of the unit 2, and are firmly fixed to the longitudinal frame 4.

However, the rear end portion of the longitudinal frame 4 to which the hook member 6 is fixed generally actively deforms the frame when the load exceeds a certain value, from the viewpoint of ensuring the safety of the occupants in the vehicle by absorbing energy in the event of a collision. Therefore, if the hook member 6 as described above is adopted, the deformation of the fixed portion of the hook member 6 in the frame 4 is prevented by the hook member 6. In some cases, the frame 4 may be biased and deformed so that it protrudes greatly in only one direction, and the hook member 6 may be blocked by other parts, such as the fuel system. There was a problem that other parts had to be moved sufficiently away from the frame 4 because there was a risk of damaging the parts. In addition, as another conventional example, a traction device is disclosed in Japanese Utility Model Application Publication No. 170191/1985, which is composed of a fixed end fixed to the vehicle body with a bolt and a hook part continuous to the fixed end. However, it still had the same problems as the above-mentioned conventional example.

The present invention was devised in view of the above, and is based on the fact that the front end and the rear end of the vehicle are fixed to the longitudinal frame of the vehicle body, and a weak part is formed in the middle of the front end and the rear end. The gist of this article is the characteristic hook member for automobiles. According to the present invention, since the hook member is formed with the fragile portion, the hook member can be easily deformed together with the longitudinal frame even in the event of a collision, so that inhibition of energy absorption by the hook member can be almost prevented. At the same time, the uneven deformation of the frame caused by the hook member can be reduced, so other parts can be moved closer to the frame than in the conventional method.
This has an advantageous effect in terms of space.

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 2 to 5.

Attach the front and rear ends of the bolts 8 to each other.
The hook member 6 is made of a thick member fixed to the longitudinal frame 4 by the bolts 8 and 10, and has a connecting hole 12 for connecting a towing rope or the like. is formed. Examples of the structure of the fragile portion 14 include those shown in FIGS. 3 to 5. The structure shown in FIG. 3 is formed by an opening 14a, and the structure shown in FIG. Accordingly, in the case shown in FIG. 5, each of the embossed portions 14c constitutes a weak portion.

According to the above configuration, the fragile portion 14 is provided in the hook member 6.
, the hook member 6 can be easily deformed together with the frame 4 even in the event of a collision, so it is possible to almost prevent the hook member 6 from obstructing energy absorption, and at the same time prevent the frame 4 from being deflected by the hook member 6. Since the ivy deformation can be reduced, other parts can be moved closer to the frame 4 than in the conventional structure, which is advantageous in terms of space.
