Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a painting cost estimating device for a damaged vehicle that estimates the cost required for painting such as exterior coating, interior coating, and undercoat when repairing a damaged vehicle. .

[Prior art]

When a vehicle's exterior panels or frame parts are damaged due to a collision or the like and repairs are requested, it is necessary to estimate the sheet metal labor and painting fees required for the repairs.

Conventionally, as a method for estimating the repair cost as described above, a method using a simple estimate as shown in FIG. 4, for example, has been used. In FIG. 4, the vertical axis represents the work time required for repair (in minutes), and the horizontal axis represents the damaged area (in d). In addition, each curve from ■ to ■ is a calculation curve for sheet metal/base treatment work depending on the difficulty level of sheet metal work, and
Material cost calculation curves and painting work time calculation curves are displayed for metallic coating and solid coating, respectively.

When using the above-mentioned simple estimate, first, the area of the damaged part is calculated by multiplying the deformed area of the damaged part by a certain coefficient.

Next, select one of the curves from ■ to ■ above depending on the difficulty of the sheet metal work, and extend a perpendicular line from the point of the damaged area calculated above on the horizontal axis of the simple estimate table. Find the intersection with the above-selected curve, extend a horizontal line to the left from the intersection, and find the sheet metal work time from the work time on the vertical axis.

Next, the painting operation time is determined from the painting operation time calculation curve using the same procedure as above.

Next, the total of the above-mentioned sheet metal work time and painting work time is calculated, and the total work time is multiplied by the lever rate (wage per hour) to calculate the wage.

Next, in the same manner as above, the material cost of the paint, that is, the paint cost, is determined from the material calculation curve of the simple estimate table.

Next, the total cost required for repair, that is, the estimated amount, is calculated by adding the above-mentioned labor fee and paint cost.

[Problems to be Solved by the Invention] As mentioned above, in the conventional estimation method using a simple estimation table, in addition to the steps of obtaining various values from the estimation table, various multiplications and additions as described above are performed. The work must be done by the user, which is complicated and takes a long time, and there is a risk of errors in the estimated amount due to calculation errors. Since there is a lot of reliance on the estimates, there is a problem in that the estimates tend to vary, which can lead to a loss of client trust.

In addition, as can be seen from Figure 4, the simple estimate table contains complex curves and detailed numerical values, so it needs to be at least as large as A4 paper in order to make it easier for users to see. Therefore, there was a problem that it was inconvenient to carry and difficult to use.

The present invention has been made to solve the problems of the prior art as described above, and the user does not need to perform calculations.
Moreover, it is an object of the present invention to provide a painting fee estimation device for damaged vehicles that is small, convenient to carry, and easy to use.
