Abstract

PURPOSE:To prevent the breakage of a fender and the miss operation of a handle by fixing a metal plate formed on the left and right lower sides of a bumper to a frame with a buffer plate and auxiliary levers and applying a buffer action to the up-and-down movement of a car body. CONSTITUTION:The flat plane section (b) of a buffer plate 2 is adjustably overlapped on one side of the flat plate section (a) of a metal plate, then the buffer plate 2 is risen upward to form a bent section (c), and multiple fitting grooves are provided on the plate to fit it to a frame. Auxiliary levers 3, 3' are adjustably fitted to the flat plate section (b) at one end and are pinched at the other end with two belt-like plates 5, 5' from above and below to form an expanded section, then an upper section is fixed to the auxiliary lever 3'. When a bumper is grounded on a rugged terrain, the flat plate section (b) of the metal plate 1 is brought into contact with the ground, thereby the elastic force is increased due to the synergetic effect of action and reaction between the bent section of the buffer plate 2 and the expanded section of the auxiliary levers 5, 5' to each other and the recovery force can be jointly retained by them.

Description

[Detailed Description of the Invention] This invention provides a method for driving an automobile, such as a four-wheel drive vehicle, because if the road surface is uneven, the vehicle body will move violently up and down. The purpose is to

Conventionally, when a four-wheeled vehicle is traveling on a rough road, such as an uneven road surface, an icy snowy road on the shoulder, or a concrete groove, the steering wheel is taken off by the vertical movement of the vehicle due to an obstacle, causing damage to the vehicle body. There were drawbacks to bringing about this.

This invention eliminates these drawbacks.

In this invention, the bent portion is provided on one side of the rear side of the metal plate so that it is formed so as to provide action and reaction due to the buffering effect, that is, the vertical movement due to the uneven surface of the ground surface, thereby providing elastic force and restoring force. This is what I did.

In this invention, by providing a bulge on the auxiliary rod, it is possible to balance the left and right shock absorption.

One embodiment of this invention will be explained with reference to the drawings: (1)
is a metal plate, which is made of iron or duralumin, which is as light and strong as possible, and whose front part is bent upward to form a slightly sled-like shape. Reference numeral (2) is a buffer plate in which a flat portion (b) is adjustedably superimposed on one side of the flat plate portion (a) of the metal plate (1), and then raised upward to form a bent portion ( C), and
A plurality of mounting grooves (4) are provided on the plate to attach it to the frame. (3) (3)' is an auxiliary rod, one end of which is a flat plate (
A), and the other end is sandwiched between two strip plates (5) and (5)' from above and below to form a bulge, and the rear upper end is fixed to the auxiliary rod (3)'. (6) is a mounting hole for the auxiliary rod, which is fixed to the frame. (7) is a drain hole.

Since the present invention is constructed as described above, as shown in FIG. 2) and the auxiliary rod (3) to fix it.

When the front part of the car body moves up and down while moving forward on an uneven road surface, the bumper part touches the ground, so the flat plate part (a) of the metal plate (1) comes into contact with the ground. Then, this force acts on the bent part of the buffer plate (2) and the bulging parts of the auxiliary rods (5) and (5)', and the synergistic reaction strengthens the elastic force and at the same time increases the restoring force. It is something that is shared.

As described above, in this invention, the metal plate (1) formed in the shape of a sled on the left and right lower sides of the bumper is fixed to the frame by the buffer plate (2) and the auxiliary rod, so that it can withstand the vertical movement of the vehicle body. Since it provides a cushioning effect, there is no risk of damage to the vehicle body, such as the fender, or incorrect operation of the steering wheel.

Claims (1)

[Scope of Claims] 1. After bending the front part of the metal plate (1) upward, a buffer plate (2) having a bent part on one rear side of the metal plate (1) is also bent on the other side. Damage prevention device for an automobile, characterized in that auxiliary rods (3) each having a buffer portion on one side are arranged opposite to each other in a freely adjustable manner and are attached to the lower surface of the vehicle body so as to reduce the impact from the ground contact surface. 3) is formed in a straight line, the damage prevention device for an automobile according to claim 1 of the utility model registration claim.
