Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for identifying accident damage to motorized vehicles. Car accidents are especially important for used car buyers, as even if a car with an accident history is perfect in appearance and function, the take-back price is often much lower than an equivalent car without an accident history. It is important to know whether a person has a background or not.

BACKGROUND OF THE INVENTION The methods used to date for determining the likelihood of accident damage involve simply visual inspection of parts that may have been damaged in an accident, such as new parts. All I had to do was pay attention to my work after the accident.

However, such visual inspection is unreliable since, for example, new welds can be treated with appropriate treatments to make them look old and indistinguishable from the original weld.

(Problems to be Solved by the Invention) There are alternative inspection methods to thermal theory2, such as non-destructive testing of materials using ultrasonic waves or X-rays. However, this type of testing is expensive and time consuming.

It cannot be adopted as an official test series for used cars.

OBJECTS OF THE INVENTION It is therefore an object of the present invention to produce an accident damage identification device for motorized vehicles that does not have the disadvantages mentioned above.

Furthermore, it is noteworthy that the present device is proposed to provide a clear and easy method for even a layperson to detect accidental damage. However, cases of extremely minor damage are excluded.

(Means and effects for solving the problems) In the present invention, the above-mentioned results can be obtained by virtue of the characteristics of the characterized parts set forth in claim (1).

Examples of advantageous aspects are listed in the dependent claims.

The benefits of the present invention are based on markings that are placed on structurally important parts of motorized vehicles that are damaged in accidents, particularly in the area of destruction, and that are destroyed and cannot be repaired if the surrounding area is deformed. Markings that can be applied to these locations using robots can be applied in a variety of different formats, such as stamps or engravings, and can be easily pasted on appropriate locations. The question is whether to use a surface-destructive sheet. In this case, it is desirable to include a mark, code, etc. on the sheet or stamp to make it difficult to forge the marking.

For example, will the fractured area be deformed due to a vehicle accident, thereby causing the seat to be damaged beyond repair?

The stamp probably changes shape depending on the severity of the accident.

Damaged seats or deformed stamps can also be easily identified during subsequent repairs to the car, giving the car buyer clear information as to whether the car has an accident history. The buyer then enters into negotiations for the purchase price.

EXAMPLE The chassis, generally designated by the reference number lO, has two longitudinal chassis bracings 18.20 extending in the direction of travel of the vehicle, with cross bracings 12.14 They are joined at the front and rear.

Bracing L & 20 in the longitudinal direction is usually the front wheel 24
．． At the same time as the front axle 22 with 26, it supports a driven rear axle 28 with rear wheels 32,34.

However, this structure is not essential. The driven rear axle 28 can also be a front axle.

In the illustrated embodiment of the chassis 10 there are two normal break areas 36, 38° 44,46 at the bracing 18,20. These fracture areas are deformed by the impact that occurs during an accident and absorb some of the momentum of the wheel. A part of the momentum absorbed in this way no longer prevents deformation of the passenger compartment. That is, the passengers are protected from these forces.

The chassis 10 is then marked at the point of direct damage in the event of an accident, and two different changes occur.

A destructible plastic sheet 40° 42 is applied to the rear destructible area 36.38 of the longitudinal bracing 18.20, which is stamped with a characteristic stamp. A corresponding destructible seat 48 is placed on the front cross-bracing which deforms even in minor collisions.

The front fracture areas 44 and 46 of the longitudinal bracing 18.20 are stamped or engraved 45.47, which can be produced during the manufacture of the chassis 10, for example using a robot. .

The breakable sheets 40, 42, 48 can be made of plastic sheets with predetermined break lines.

When the deformation of these plastic sheets becomes thicker,
It is damaged at a predetermined line of failure, and it is usually impossible to restore it to its original shape.

However, particularly good results can be obtained using a brittle, easily broken vinyl coating sold by 3M Company under the trade name Scotchmark®. This type of vinyl coating is coated with a high grade acrylic adhesive that has good initial adhesion and excellent final adhesion on smooth, clean surfaces.

After printing this brittle vinyl foil, the printed surface is coated with a two-component varnish known from German publication 2941087 by a screen printing process.

The chassis 10 of this vehicle is deformed in the event of an accident, in particular its destruction areas 36.38, 44.46, whereby a corresponding deformation occurs in the destructible seats 40, 42.48 or imprints or markings 45. It will replace 47. In particular, the fragile vinyl adhesive sheet breaks apart due to large deformation and loses its original shape, so it is impossible to precisely restore these marks to their original shape when repairing the vehicle.

(Effect of the invention) Since it is possible for even an amateur to recognize the corresponding deformation of the markings immediately after an accident, it is difficult to determine whether there is a history of accidents where the chassis deforms. be.

It is of course possible to apply these markings to other locations, for example on the inner surface of parts of the vehicle body that are particularly prone to damage based on experience in the event of an accident.
