[0002] For some vehicles with multi-layered side panels, such as refrigerated trucks, the deformation of the side panels needs to be measured after the strength test. However, the deformation of the inner side panels caused by the pressure applied inside the compartment during the strength test is inconsistent with the deformation of the outer side panels. Therefore, the internal deformation cannot be used to replace the external deformation. How to accurately measure the deformation of the outer side panels of the compartment has become an urgent problem to be solved.

[0003] In the related art, the test method for the deformation of the vehicle's outer panel is mainly a ground projection measurement method, which uses a plumb line to project the plane where the vehicle's outer panel is located to the ground to obtain a projection line; then, the relative highest point in the deformation area of ​​the vehicle's outer panel is projected to the ground using a plumb line to obtain a projection point; then, the distance between the projection point and the projection line is measured, and the distance is used as the deformation of the vehicle's outer panel deformation area.

[0045] In a first aspect, an embodiment of the present application provides a method for measuring the deformation of an outer side panel of a vehicle compartment.

[0046] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the method for measuring the deformation of the outer side panel of a vehicle compartment of the present application. Figure 1 As shown, the method for measuring the deformation of the outer side panel of the carriage includes:

[0047] Step 110, when the emission lines formed by each laser source on the angle adjustment device coincide with the reflection lines reflected by the measuring plates corresponding to each laser source, determine the total height of the light spot formed by the laser source irradiating on the measuring plate relative to the plane where the outer plate of the carriage is located, wherein the measuring plate is arranged at the edge line in the length direction and the edge line in the height direction of the outer plate of the carriage, the angle adjustment device is arranged in the deformation area to be measured of the outer plate of the carriage, the angle adjustment device includes a base, an angle adjustment block and a laser source fixing block, the base and the angle adjustment block are connected by a first rotating shaft, the angle adjustment block and the laser source fixing block are connected by a second rotating shaft, the first rotating shaft is used to rotate the angle adjustment block in the horizontal direction, the second rotating shaft is used to rotate the laser source fixing block in the vertical direction, two laser sources are arranged on the laser source fixing block, and the angle between the emission lines formed by the two laser sources is a right angle;

[0048] The deformation region to be measured of the outer panel of the vehicle compartment is usually in the shape of a conical protrusion, and the angle adjustment device is arranged in the deformation region to be measured of the outer panel of the vehicle compartment, usually on an inclined surface of the conical protrusion.

[0049] It should be noted that the method for measuring the deformation of the outer side panel of the vehicle compartment in the present application requires the use of a dedicated angle adjustment device and a measuring plate.

Preferably, the base is a magnetic base, which is adsorbed on the deformation area to be measured on the outer side panel of the car when in use. The T-shaped component in the figure is the laser source fixing block, and the V-shaped component is the angle adjustment block. The angle adjustment block is provided with two rotation axes in different directions, namely the first rotation axis and the second rotation axis. These two rotation axes provide two degrees of freedom of rotation in different directions. Each rotation axis has an angle marking ring at one end, and the original position of the angle marking ring is 0 scale. The laser source is responsible for emitting a linear laser beam, and the angles of the two emitted laser lines are right angles.

[0051] Figure 3 This is a schematic diagram of the working condition of the method for measuring the deformation of the outer side panel of the carriage in this application. Figure 3 Among them, serial number 12 is an angle adjustment device, serial number 13 is a measuring plate, and serial number 14 is an outer side plate of the carriage.

[0052] By adjusting the first rotating shaft and the second rotating shaft on the angle adjusting device, the emission lines formed by the laser sources on the angle adjusting device and the reflection lines reflected by the corresponding measuring plates of the laser sources are made to coincide with each other. When coincident, the laser source fixing block is perpendicular to the plane where the outer side plate of the carriage is located.

[0053] The measuring plate is a flat reflective plate, and the total height of the light spot formed by the laser source irradiating the measuring plate relative to the plane where the outer side plate of the carriage is located can be determined by image processing technology.

[0054] Furthermore, the measuring plate is also provided with a scale plate and a measuring slide rail, the scale plate is arranged in a direction perpendicular to the plane direction of the outer side plate of the carriage, and the measuring slide rail is arranged in a direction parallel to the plane direction of the outer side plate of the carriage. Figure 4 A schematic diagram of the structure of a measurement board provided in one embodiment of the present application, Figure 4Serial number 8 is a scale plate, serial number 9 is a measuring plate, serial number 10 is a measuring slide rail, and serial number 11 is a measuring plate base. Preferably, the measuring plate base is a magnetic base for fixing, and is adsorbed on the edge line of the length direction and the edge line of the height direction of the outer plate of the carriage when in use; the scale plate can be millimeter-level, used to indicate the reading; the measuring slide rail can slide parallel to the scale plate direction, used to assist in reading.

[0055] When a scale plate and a measuring slide rail are arranged on the measuring plate, the method of determining the total height of the light spot formed by the laser source irradiating the measuring plate relative to the plane where the outer side plate of the carriage is located includes:

[0056] After the measuring slide is moved to the position of the light spot formed by the laser source on the measuring plate, the first value corresponding to the measuring slide on the scale plate is determined, and the first value is used as the total height of the light spot relative to the plane where the outer side plate of the car is located, so that relevant personnel can quickly and accurately read the total height of the light spot relative to the plane where the outer side plate of the car is located from the scale plate.

[0057] Step 120, determining a first rotation angle of the angle adjustment block and a second rotation angle of the laser source fixing block;

[0058] In a specific implementation, the first rotation angle of the angle adjustment block is determined by reading the value of the first angle mark ring, and the second rotation angle of the laser source fixing block is determined by reading the value of the second angle mark ring.

[0059] Step 130: Based on the first rotation angle, determine that the first line segment is converted to a first height perpendicular to the plane where the outer side panel of the vehicle compartment is located, and the first line segment is a line segment corresponding to the height between the first rotation axis and the base of the angle adjustment device;

[0060] In a specific implementation, based on the first rotation angle, it is determined that the first line segment is converted to a first height perpendicular to the plane where the outer side panel of the vehicle compartment is located, in preparation for determining the deformation amount of the deformation area to be measured.

[0061] Based on the first rotation angle, the first line segment is determined to be converted to a first height perpendicular to the plane where the outer side panel of the carriage is located. The corresponding formula is:

[0062] l a1 ′=l a1 *cosθ1

[0063] Among them, l a1 ' is the first height, l a1 is the length of the first line segment, and θ1 is the first rotation angle.

[0064] Step 140: Based on the second rotation angle, determine that the second line segment is converted to a second height perpendicular to the plane where the outer side panel of the vehicle compartment is located, and the second line segment is a line segment corresponding to the height of the second rotation axis from the first rotation axis;

[0065] In a specific implementation, based on the second rotation angle, it is determined that the second line segment is converted to a second height perpendicular to the plane where the outer side panel of the vehicle compartment is located, in preparation for determining the deformation amount of the deformation area to be measured.

[0066] The second line segment is determined to be converted to a second height perpendicular to the plane where the outer side panel of the carriage is located based on the second rotation angle. The corresponding formula is:

[0067] l a2 ′=l a2 *cosθ2

[0068] Among them, l a2 ' is the second height, l a2 is the length of the second line segment, and θ2 is the second rotation angle.

[0069] Step 150: Determine the deformation amount of the deformation area to be measured by comprehensively considering the total height, the first height, the second height and the third height, wherein the third height is the height of the laser source from the second rotation axis.

[0070] Because when the emission lines formed by each laser source on the angle adjustment device coincide with the reflected lines reflected by the measuring plates corresponding to each laser source, the laser source fixing block is perpendicular to the plane where the outer side plate of the carriage is located, so the third height directly selects the height of the laser source from the second rotation axis without the need for conversion.

[0071] Among them, the measurement reference planes of the total height, the first height, the second height and the third height are unified, which are all the planes where the outer side panels of the carriage are located.

[0072] The total height, the first height, the second height and the third height are comprehensively considered to determine the deformation amount of the deformation area to be measured, and the corresponding formula is:

[0073] d = l c -l ′ a1 -l ′ a2 -l a3

[0074] Where d is the deformation of the deformation area to be measured, l c is the total height, l a1 ' is the first height, l a2 ' is the second height, l a3 The third height.

[0075] In this embodiment, when the emission lines formed by each laser source on the angle adjustment device coincide with the reflection lines reflected by the measurement plates corresponding to each laser source, the total height of the light spot formed by the laser source irradiating on the measurement plate relative to the plane where the outer side plate of the carriage is located is determined, wherein the measurement plate is arranged at the edge line in the length direction and the edge line in the height direction of the outer side plate of the carriage, the angle adjustment device is arranged in the deformation area to be measured of the outer side plate of the carriage, the angle adjustment device includes a base, an angle adjustment block and a laser source fixing block, the base and the angle adjustment block are connected by a first rotating axis, the angle adjustment block and the laser source fixing block are connected by a second rotating axis, the first rotating axis is used to rotate the angle adjustment block in the horizontal direction, and the second rotating axis is used to rotate the laser source fixing block in the vertical direction, two laser sources are arranged on the laser source fixing block, and the angle between the emission lines formed by the two laser sources is a right angle ; Determine a first rotation angle of the angle adjustment block and a second rotation angle of the laser source fixing block; based on the first rotation angle, determine that the first line segment is converted to a first height perpendicular to the plane where the outer panel of the car is located, the first line segment is a line segment corresponding to the height between the first rotation axis and the base of the angle adjustment device; based on the second rotation angle, determine that the second line segment is converted to a second height perpendicular to the plane where the outer panel of the car is located, the second line segment is a line segment corresponding to the height of the second rotation axis from the first rotation axis; comprehensively determine the total height, the first height, the second height and the third height, determine the deformation amount of the deformation area to be measured, the third height is the height of the laser source from the second rotation axis, and the plane where the outer panel of the car is located is used as the reference plane. The measurement method is relatively simple, and the deformation amount of the deformation area to be measured is determined by mathematical operation, which can improve the measurement accuracy.

[0076] In actual situations, since the plane of the outer panel of the carriage is uneven, after the angle adjustment device is arranged in the deformation area to be measured on the outer panel of the carriage, it is necessary to adjust the angle of the outer panel of the carriage. a1 , l a2 and a3 The actual length is checked. The actual sum is obtained by adding the actual values ​​of the three, and the theoretical sum is obtained by adding the theoretical values ​​of the three, and the difference between the actual sum and the theoretical sum is determined. When determining the deformation amount of the deformation area to be measured, the influence of the above difference is considered to further improve the accuracy of the measurement. The corresponding formula is:

[0077] d = l c -l ′ a1 -l ′ a2 -l a3 -s

[0078] Where d is the deformation of the deformation area to be measured, l c is the total height, l a1 ' is the first height, la2 ' is the second height, l a3 is the third height and s is the difference.

[0079] Furthermore, in one embodiment, the method further includes:

[0080] The arrangement position of the angle adjustment device in the deformation area to be measured of the outer side panel of the vehicle compartment is adjusted, and the maximum value of the deformation amounts of the deformation area to be measured at different arrangement positions is determined, and the maximum value is used as the maximum deformation amount of the deformation area to be measured.

[0081] Because the deformation area to be measured of the outer panel of the vehicle compartment is usually in the shape of a conical protrusion, the angle adjustment device is usually arranged on the inclined surface of the conical protrusion. In order to determine the maximum deformation of the deformation area to be measured, it is necessary to adjust the arrangement position of the angle adjustment device in the deformation area to be measured of the outer panel of the vehicle compartment for multiple times, and determine the maximum value of the deformation of the deformation area to be measured at different arrangement positions. The maximum deformation of the deformation area to be measured determined in the above manner is also based on the plane where the outer panel of the vehicle compartment is located as the reference plane, which can improve the measurement accuracy.
