Embodiments of the present invention will be described with reference to the drawings. In addition, the same reference numerals are given to common parts in each figure, and duplicate description is omitted.

FIG. 1 is a flowchart of a target positioning method according to an embodiment of the present invention. The target is used when the computer mounted on the vehicle recognizes the mounting position of the detection device (camera, radar, sensor, etc.) that supports safe driving, or when adjusting the mounting position on the vehicle, and the detection device operates correctly. It is a reference tool when confirming whether to do it. The target, sometimes referred to as a reflector, is stated in the vehicle maintenance manual to be used by each vehicle manufacturer as specified or instructed. The target is used every time the detection device is replaced or repaired, the glass of the vehicle in front of the detection device is replaced, or the sheet metal of the vehicle body on which the detection device is attached is repaired.

Aiming refers to the ability of the detection device to hit the desired location. This aiming adjustment is performed for each disassembly and maintenance such as replacement and repair of the detection device, replacement of the glass of the vehicle in front of the detection device, and correction of the sheet metal of the vehicle body on which the detection device is attached. Aiming adjustment refers to the work of making the computer mounted on the vehicle recognize the mounting position of the detection device by hitting the central axis of the detection device on the target.

General vehicle maintenance manuals require that the floor plane on which the vehicle is placed be horizontal when the mechanic makes aiming adjustments. Therefore, in the present embodiment, it is assumed that the floor plane on which the vehicle is placed is a horizontal plane. Each step of FIG. 1 will be described in each embodiment.

FIG. 2 is a diagram showing a positional relationship between a target and a vehicle according to an embodiment of the present invention. FIG. 2 is a top view of the vehicle 100. Each black circle (A to F, X to Z) is a point on the horizontal plane on which the vehicle 100 is placed, and is used when explaining each embodiment. The black circle A represents a point perpendicular to the horizontal plane from the center of the front emblem of the vehicle 100. The black circle B represents a point perpendicular to the horizontal plane from the center of the rear emblem of the vehicle 100. Black circles A and B represent the center of the vehicle width.

The black circle C represents a point perpendicular to the horizontal plane from the center of the right front wheel of the vehicle 100. Similarly, the black circle D represents the point perpendicular to the horizontal plane from the center of the right rear wheel, the black circle E from the center of the left front wheel, and the black circle F from the center of the left rear wheel.

The black circle X is also a point on the horizontal plane, and is provided on a straight line passing through the black circle A and the black circle B. In a general vehicle maintenance manual, the black circle X is a reference position for installing the target. The distance from the black circle X to the black circle A varies depending on each automobile manufacturer, but is about 2 to 5 m (meters). Here, the "position that serves as a reference for the position where the target is installed" refers to the following two cases. In the first case, the black circle X is the position where the target is installed. The second case is a case where the target is installed at a position separated from the black circle X by about several tens of centimeters on the left side or the right side. The reason there are two cases is that the position of the target specified by each automobile manufacturer may differ depending on the vehicle.

Depending on the vehicle type, there is also a vehicle maintenance manual that requires that targets be installed on the black circles Y and Z. The black circles Y and Z are also points on the horizontal plane, and the black circle Y is provided on a straight line passing through the black circle C and the black circle D, and the black circle Z is provided on the straight line passing through the black circle E and the black circle F. The distance from the black circle Y to the black circle C and the distance from the black circle Z to the black circle E vary depending on each automobile manufacturer, but are about 3 to 5 m (meters).

(Structure of the first embodiment)
The first embodiment describes the case where the black circle X in FIG. 2 is determined as the reference position of the position where the target is placed. Briefly, first, a straight line passing through two points (points A and B) on the horizontal plane corresponding to the center of the front emblem and the center of the rear emblem at the center of the vehicle width of the vehicle 100 is obtained. Next, the distance from this straight line to the point A is measured, and the point X at a predetermined distance is determined. In the following, how to use each component of the target positioning tool will be described with reference to FIGS. 3 to 7 along with each step of FIG.

FIG. 3 is a diagram for explaining how to use the vertical ruler according to the first embodiment. The method of using this vertical ruler corresponds to step S110 in FIG. FIG. 3 is a view of the vehicle 100 as viewed from the front left.

The mechanic places the vehicle 100 on the floor plane and the vertical ruler 200 in front of the vehicle 100. On the front side of the vehicle 100, a front side emblem 110 representing the center of the vehicle width is provided. Point 111 indicates the center of the front emblem 110.

The vertical ruler 200 includes a horizontal base portion 210, a ruler portion 220 provided perpendicular to the base portion 210, and a mounting base 230 to which the point-shaped laser pointer device 300 can be attached. Using the dotted laser pointer device 300, the tip of the laser beam 301 (indicated by the dotted line) is aligned with the point 111 on the front emblem 110. Here, the ruler portion 220 is used to draw a perpendicular line on the floor plane and mark the floor plane. Further, the base portion 210 may be variously deformed as long as it supports the vertical ruler portion 220. Further, as the point laser pointer device 300, the point laser pointer function of the laser rangefinder 310 described in S170 may be used. The ruler portion 220 is provided with a scale 221. The scale 221 is not an essential component of the ruler 220.

With the tip of the laser beam of the point laser pointer device 300 aligned with the point 111, the floor of the lower end of the ruler portion 220 (directly below the point laser pointer device 300) is marked. This marked point is a black circle A. Here, instead of marking directly on the floor, a peelable sticker may be attached to the floor and the sticker may be marked. This is because it may be difficult to mark the floor plane of an automobile maintenance shop with a pen. In addition, the position where the vehicle is placed on the floor is different each time, and if the vehicle is directly marked on the floor, it takes time to erase it.

That is, in step S110 of FIG. 1, a step of marking a first point (black circle A, that is, a point on the front side of the vehicle) on a horizontal floor plane on which the vehicle 100 is installed by using a vertical ruler 200 and a point laser pointer device 300. Is. Here, the point-shaped laser pointer device 300 may use an external general-purpose product, and is not an essential configuration for the target positioning tool according to the present embodiment. That is, in FIG. 3, the vertical ruler 200 is an essential component of the target positioning tool according to the present embodiment.

FIG. 4 is a diagram for explaining a method of aligning the marking plate according to the first embodiment to the first point. This method of aligning the marking plate corresponds to step S120 in FIG. FIG. 4 is a view of the vehicle 100 viewed from the front left, as in FIG.

The marking plate 400 includes a thin rectangular parallelepiped vertical plate 410, and a first support portion 431 and a second support portion 432 that support the vertical plate 410. Further, on the vertical plate 410, a first vertical line 421 passing through the center thereof is drawn on the front surface, the upper surface, and the back surface. In FIG. 4, the back surface (facing the front side of the vehicle 100) is not shown. Similarly, a second vertical line 422 and a third vertical line 423 are drawn at both ends of the vertical plate 410. Here, the use of the marking plate 400 is as follows: first, at the point A, the first linear laser light described later can pass through a vertical line, and secondly, the laser of the laser range finder 310 described later can be used. It can be applied, and thirdly, the first linear laser beam can pass through the vertical line at the point E or the point F of the tire described later.

The size of the vertical plate 410 is about 65 mm in height, 150 mm in width, and 4 mm in thickness, and the second vertical line 422 and the third vertical line 423 are provided at positions separated from both ends by about 4 mm. The second vertical line 422 and the third vertical line 423 are not essential components in the first embodiment, but are used in the second embodiment described later. Further, the reason why the first vertical line 421 is provided so as to pass through the center of the vertical plate 410 is due to the positional relationship between the first support portion 431 and the second support portion 432, and is not provided in the center. May be good.

In the marking plate 400, the lower end of the first vertical line 421 is aligned with the black circle A on the floor plane, and the floor plane so that the back surface (not shown) of the vertical plate 410 faces the front side of the vehicle 100. Install in. That is, step S120 in FIG. 1 is a step of aligning the vertical line (corresponding to the first vertical line 421) provided on the marking plate 400 to the first point (corresponding to the black circle A). Further, in FIG. 4, the marking plate 400 is an indispensable component of the target positioning tool according to the present embodiment.

In step S130 of FIG. 1, for the rear emblem of the vehicle 100 of FIG. 2, a vertical ruler 200 and a point laser pointer device 300 are used as in step S110, and a second point (black circle B, that is, rear of the vehicle) is formed on the floor plane. This is the step of marking the point on the side. Since the same method as in FIGS. 3 and 4 may be used for the rear emblem of the vehicle 100 in FIG. 2, detailed description thereof will be omitted.

FIG. 5 is a diagram for explaining the positional relationship between the marking plate and the linear laser pointer device according to the first embodiment. With reference to FIG. 5, the linear laser pointer so that the line of the first linear laser light from the linear laser pointer device of FIG. 1 passes through the second point and the vertical line of the marking plate. The method of "installing the device on the floor plane" will be described.

Here, FIG. 5 is a side view of the vehicle 100. However, for convenience of explanation, the marking plate 400 and the linear laser pointer device 500 are drawn as if they are viewed from diagonally behind.

The straight line passing through the black circle A and the black circle B is a line on the floor plane and is a straight line passing through the center of the vehicle width of the vehicle 100. A marking plate 400 is placed on the black circle A so that the lower end of the first vertical line 421 is aligned with the black circle A. The linear laser pointer device 500 is placed on this straight line at a position behind the vehicle from the black circle B.

The reason why the linear laser pointer device 500 is placed at a position behind the vehicle from the black circle B is that the first linear laser light line 511 from the first laser irradiation port 510 of the linear laser pointer device 500 is the second point. (Black circle B) and the first vertical line 421 of the marking plate 400 are to be passed. Since the line 511 of the first linear laser light is a so-called line laser, it does not hit the first vertical line 421 at a point, but at the line 511-1. The reason why the first laser irradiation port 510 is drawn on the front surface of the linear laser pointer device 500 is for easy understanding. The first laser irradiation port 510 may be on the back surface (not shown).

The linear laser pointer device 500 may use an external general-purpose product, and is not an essential configuration for the target positioning system according to the present embodiment. For example, as the linear laser pointer device 500, a commercially available laser marking device for construction may be used. The architectural laser marking device can irradiate two vertical lines and one horizontal line with a laser line. The two vertical lines make the ground ink stick out as a cross line.

In the case of the linear laser pointer device 500 of the present embodiment, the line lasers irradiated from the first laser irradiation port 510 and the second laser irradiation port 520 correspond to two vertical lines, and the ground ink can be output as a cross line. .. Further, the line laser irradiated from the third laser irradiation port 530 corresponds to one horizontal line.

In FIG. 5, the linear laser pointer device 500 irradiates the line laser only from the first laser irradiation port 510. On the other hand, the second laser irradiation port 520 and the third laser irradiation port 530 turn off their respective laser irradiation switches so that the laser is not irradiated.

Further, the line laser from the first laser irradiation port 510 need only be able to irradiate the front side of the vehicle 100. This is the first line of linear laser light (511 and 511-1). In FIG. 5, for convenience of explanation, the light beam of the line laser emitted to the rear of the vehicle 100 is not drawn. Also in FIG. 5, the marking plate 400 is an essential component of the target positioning tool according to the present embodiment.

FIG. 6 is a diagram for explaining a method of using the mobile table (No. 1) according to the first embodiment. With reference to FIG. 6, S150 “a base on which the laser distance meter is installed and a moving table provided with an inclined plate having a line perpendicular to the base parallel to the floor plane are provided with a first linear laser. The method of "installing so that the line of light passes through the right-angled line" and S160 "Move the moving table with the line of the first linear laser light passing through the right-angled line, and determine with the laser range meter. The method of measuring the distance of the laser will be described.

FIG. 6 is a side view of the vehicle 100 as in FIG. However, the marking plate 400, the linear laser pointer device 500, and the moving table 600 are drawn as if they are viewed from diagonally behind for convenience of explanation. Further, regarding the mobile table 600, the mobile table 600 is enlarged and drawn in order to make the explanation of each configuration easy to understand, but the actual size is small, and the laser light 311 of the laser range finder 310 is a marking plate. It is about the size of 400.

The moving table 600 can be attached with a base 610 having four feet (611, 612, 613, 614) having the same height and an enclosure 615 surrounding the four corners, an inclined plate 620, and a laser range finder 300. It includes a first mounting portion 630 and a second mounting portion 640 to which the linear laser pointer device 500 can be mounted later. The inside of the enclosure 615 is open so that the floor plane can be seen. Further, the first mounting portion 630 and the second mounting portion 640 are provided inside the enclosure portion 615. Further, since the heights of the four feet (611, 612, 613, 614) are equal, the enclosure 615 is parallel to the floor plane and the base 610 is also parallel to the floor plane. In addition, the first mounting portion 630 and the second mounting portion 640 are also parallel to the floor plane.

The inclined plate 621 is inclined with respect to the surrounding portion 615 at a predetermined inclination angle θ. A line perpendicular to the base parallel to the floor plane (center line passing through the center of the inclined plate in this figure) 621 is drawn on the inclined plate 621. The mobile table 600 is installed so that the first linear laser beam line 511-2 passes through the center line 621. With the first linear laser beam line 511-2 passing through the center line 621, the distance to the marking plate 400 (that is, the black circle A) is measured using the laser range finder 310. The moving table 600 is moved back and forth on the straight line AB so that this distance becomes a predetermined distance described in the vehicle maintenance manual.

The reason why the inclined plate 620 is inclined at a predetermined inclination angle θ is that the first linear laser beam line 511-2 does not appear when θ = 0 °, and the first when θ = 90 °. The line 511-2 of the linear laser beam appears, but it is not known whether the moving table 600 is installed at a right angle to the straight line AB. That is, the inclination angle θ may be appropriately set in the range of 0 ° <θ <90 °.

Further, although the center line 621 is the center of the inclined plate 620, it may be slightly shifted to the left or right instead of the center, or may be shifted to the left or right within a range in which the target of S180 of FIG. 1 to be described later can be positioned. That is, the center line 621 may be a line perpendicular to the base parallel to the floor plane of the inclined plate 621.

Here, as described with reference to FIGS. 3 and 5, the laser range finder 310 and the linear laser pointer device 500 may use an external general-purpose product, and in the configuration essential for the target positioning tool according to the present embodiment. Absent. Therefore, in FIG. 6, the marking plate 400 and the moving table 600 are essential components for the target positioning tool according to the present embodiment.

FIG. 7 is a diagram for explaining a method of using the mobile table (No. 2) according to the first embodiment. With reference to FIG. 7, the method of S170 “installing the linear laser pointer device on the base of the moving table” of FIG. 1 and S180 “orthogonal to the first linear laser light of the linear laser pointer device”. The method of "determining the point where the second linear laser light and the first linear laser light intersect at the position of the target" will be described.

In FIG. 7, the position of the moving table 600 remains at a predetermined distance from the black circle A by using the laser range finder 300 as described in FIG. The linear laser pointer device 500 is attached to the second attachment portion 640 of the moving table 600. Further, since the marking plate 400 and the laser range finder 300 are not particularly required, they are not drawn in FIG. 7. The above corresponds to the method of S170 “installing the linear laser pointer device on the base of the moving table” in FIG.

Next, the linear laser pointer device 500 attached to the second attachment portion 640 provided inside the open enclosure portion 615 will be described. The first line laser is irradiated to the floor plane from the first irradiation port 510 of the linear laser pointer device 500, and the line 511 of the first linear laser light is drawn on the floor plane. Further, the second line laser is irradiated to the floor plane from the second irradiation port 520, and the line 521 of the second linear laser light is drawn on the floor plane. That is, the ground ink can be produced at the cross line. Further, the line 511 of the first linear laser light and the line 521 of the second linear laser light intersect at a right angle (90 °). This intersection corresponds to the black circle X in FIG.

In this way, the position of the target is the point where the second linear laser light orthogonal to the first linear laser light of the S180 “linear laser pointer device” of FIG. 1 intersects with the first linear laser light. Can be decided. Here, as described with reference to FIG. 5, the linear laser pointer device 500 may use an external general-purpose product, and is not an essential configuration for the target positioning tool according to the present embodiment. Therefore, in FIG. 7, the moving table 600 is an indispensable component of the target positioning tool according to the present embodiment.

As described above, the method of positioning the target according to the first embodiment (when the black circle X in FIG. 2 is determined as the position where the target is placed) is described with respect to the flowchart of FIG. 1 and the method of using each component of FIGS. 3 to 7. It was explained with reference to figure. Further, as the target positioning tool according to the first embodiment, the vertical ruler 200, the marking plate 400, and the moving table 600 are indispensable components.

(Action and effect of the first embodiment)
A point laser pointer device 300, a laser distance meter 310, and a linear laser pointer device 500, which are external general-purpose products, are used as a target positioning tool including a vertical ruler 200, a marking plate 400, and a moving table 600. As a result, in the first embodiment, since it is not necessary to use the plumb bob weight, it is not necessary to align the laser beam with one point of the plumb bob weight, and the position of the target on the horizontal floor plane without any trouble. Has the effect of being able to easily determine.

(Structure of the second embodiment)
The second embodiment describes a case where the black circle Y or the black circle Z in FIG. 2 is determined as the reference position of the position where the target is placed. Since the method of determining the black circle Y or the black circle Z is the same, the case of determining the black circle Z will be described below. In addition, the following five work procedures are required for the general method described in the vehicle maintenance manual. As the first procedure, black circles A and B are marked with a downward swing weight, and a thread passing through the black circles A and B (a thread is also attached in front of the black circle A) is attached to the floor surface. As a second procedure, the black circles C and D are marked with a downward swing weight, the thread passing through the black circles C and D is attached to the floor surface, and the black circle Y on the thread at a predetermined distance in front of the black circle C is marked. do. As a third procedure, the black circles E and F are also marked in the same manner as in the first procedure. As a fourth procedure, a thread passing through the black circles Y and Z is attached to the floor surface. As the fifth procedure, the black circle X is the point where the threads of the first and fourth procedures intersect. On the other hand, according to the present embodiment, it is sufficient to determine either the black circle Y or the black circle Z, and it is not necessary to determine both, which has the effect of shortening the working time as compared with the method described in the maintenance manual. This is a point where a point Y or Z is determined at a predetermined distance from the point C or E, a right-angled line is drawn from the point Y or Z using a linear laser pointer device 500, and the point intersects the extension lines of the points A and B. This is because it is set to X.

To briefly explain the case of determining the black circle Z, first, a straight line passing through two points (points E and F) on the horizontal plane corresponding to the center of the left front wheel and the center of the left rear wheel of the vehicle 100 is obtained. Next, the distance from this straight line to the point E is measured, and the point Z at a predetermined distance is determined. In the following, how to use each component of the target positioning tool will be described with reference to FIGS. 8 to 13 along with each step of FIG. The description of the same reference numerals as in the first embodiment will be omitted as appropriate to avoid duplicate explanations. Therefore, see also the description of the first embodiment.

FIG. 8 is a diagram for explaining how to use the vertical ruler according to the second embodiment. The method of using this vertical ruler corresponds to step S110 in FIG. FIG. 8 is a view of the vehicle 100 as viewed from the front left.

The mechanic places the vehicle 100 on the floor plane and the vertical ruler 200 in front of the vehicle 100. The left front wheel of the vehicle 100 includes a rubber tire 120 and a metal wheel 130 provided inside the tire 120. Point 131 indicates the center of the left front wheel 130.

The vertical ruler 200 includes a horizontal base portion 210, a ruler portion 220 provided perpendicular to the base portion 210, and a mounting base 230 to which the point-shaped laser pointer device 300 can be attached. Using the point laser pointer device 300, the tip of the laser beam 301 (indicated by the dotted line) is aligned with the point 131 of the wheel 130 of the left front wheel. The ruler portion 220 is provided with a scale 221.

With the tip of the laser beam of the point laser pointer device 300 aligned with the point 131, the floor of the lower end of the ruler portion 220 (directly below the point laser pointer device 300) is marked. This marked point is a black circle E.

The portion of the circle L drawn by the dotted line around the lower part of the vertical ruler 200 is enlarged in FIG. FIG. 9 is an enlarged view of the lower part of the vertical ruler according to the second embodiment.

The vertical ruler 200 is provided with a guide portion 222 at the lower ends of the ruler portion 220 and the base portion 210. The guide portion 222 is marked with two arrows (222-1 and 222-2).

Arrow 222-1 describes "0 (mm)", which means that it is 0 mm from the left end (scale 221 side) of the ruler portion 220. Arrows 222-1 are used when marking the black circles A and B described in the first embodiment on the floor plane.

On the other hand, arrow 222-2 describes "+10 mm", which means that the ruler portion 220 is 10 mm away from the left end. The arrow 222-2 may be used when marking the black circle E and the black circle F (also the black circle C and the black circle D) described in the second embodiment on the floor plane.

The reason for using the arrow 222-2 in the second embodiment is that when the marking plate 400 is placed at the point E, if the ends of the tire 120 and the marking plate 400 hit each other, the arrow 222 of the vertical ruler 400 This is because the position marked in 1 and the vertical line (third vertical line 423) of the marking plate 400 may deviate from each other.

Such a phenomenon occurs because the tire 120 may sink due to the weight of the vehicle 100, and the rubber portion of the tire 120 may come out from the vehicle outer plate of the fender (upper portion of the wheel or its surroundings) portion. Especially in the case of soft rubber such as studless tires, it goes out. Therefore, even if the marking plate 400 is brought into contact with the tire 120 and placed on the floor plane, the marking plate 400 may be installed on the outside of the vehicle more than expected.

Therefore, in the second embodiment, the marking plate 400 may be installed outside the vehicle more than expected, and the second vertical line 422 and the third vertical line 423 of the marking plate 400 are In consideration of the fact that they are provided at positions separated from both ends by about 4 mm, it was decided to use the arrow 222-2. The scale 221 provided on the ruler portion 220 is used to measure the height from the floor plane to the fender. For the scan tool for aiming adjustment provided by each automobile manufacturer, perform various calculations specified in each vehicle maintenance manual using the height from the floor plane to the fender, and enter the calculation results. This is because it is required.

Step S110 of FIG. 1 is a step of marking the first point (black circle E, that is, the point on the left front wheel side) on the horizontal floor plane on which the vehicle 100 is installed by using the vertical ruler 200 and the point laser pointer device 300. is there.

FIG. 10 is a diagram for explaining a method of aligning the marking plate according to the second embodiment to the first point. This method of aligning the marking plate corresponds to step S120 in FIG. FIG. 10 is a view of the vehicle 100 viewed from the front left, as in FIG.

In FIG. 10, as in FIG. 4, a first support portion 431 and a second support portion 432 that support the vertical plate 410 are provided on the front surface. In the marking plate 400, the lower end of the third vertical line 423 is aligned with the black circle E on the floor plane, the vertical plate 410 is placed at a right angle to the vehicle 100, and the back surface of the vertical plate 410 (not shown). Is installed on the floor plane so that the vehicle 100 faces the rear side. That is, step S120 in FIG. 1 is a step of aligning the vertical line (corresponding to the third vertical line 423) provided on the marking plate 400 to the first point (corresponding to the black circle E).

In step S130 of FIG. 1, for the left rear wheel of the vehicle 100 of FIG. 2, a vertical ruler 200 and a point laser pointer device 300 are used as in step S110, and a second point (black circle F, that is, rear of the vehicle) is formed on the floor plane. This is the step of marking the point on the side. Since the same method as in FIGS. 8 to 10 may be used for the left rear wheel of the vehicle 100 in FIG. 2, detailed description thereof will be omitted.

FIG. 11 is a diagram for explaining the positional relationship between the marking plate and the linear laser pointer device according to the second embodiment. With reference to FIG. 11, the linear laser pointer so that the line of the first linear laser light from the linear laser pointer device of FIG. 1 passes through the second point and the vertical line of the marking plate. The method of "installing the device on the floor plane" will be described.

Here, FIG. 11 is a side view of the vehicle 100. However, for convenience of explanation, the marking plate 400 and the linear laser pointer device 500 are drawn as if they are viewed from diagonally behind.

The straight line passing through the black circle E and the black circle F is a line on the floor plane, and is a straight line passing in front of the vehicle 100 and beside the left front wheel and the left rear wheel. The marking plate 400 is placed on the black circle E so that the lower end of the third vertical line 423 matches the black circle E. The linear laser pointer device 500 is placed on this straight line at a position behind the vehicle from the black circle F.

The reason why the linear laser pointer device 500 is placed at a position behind the vehicle from the black circle F is that the first linear laser light line 511 from the first laser irradiation port 510 of the linear laser pointer device 500 is the second point. (Black circle F) and the third vertical line 423 of the marking plate 400 are to be passed. It is also because the linear laser pointer device 500 and the tire interfere with each other at the position of the black circle F. Since the line 511 of the first linear laser light is a so-called line laser, it does not hit the third vertical line 423 at a point, but hits the line 511-1.

FIG. 12 is a diagram for explaining a method of using the mobile table (No. 1) according to the second embodiment. With reference to FIG. 12, S150 “a base on which the laser distance meter is installed and a moving table provided with an inclined plate having a line perpendicular to the base parallel to the floor plane are provided with a first linear laser. The method of "installing so that the line of light passes through the right-angled line" and S160 "Move the moving table with the line of the first linear laser light passing through the right-angled line, and determine with the laser range meter. The method of measuring the distance of the laser will be described.

FIG. 12 is a side view of the vehicle 100 as in FIG. 11. However, the marking plate 400, the linear laser pointer device 500, and the moving table 600 are drawn as if they are viewed from diagonally behind for convenience of explanation. Further, regarding the mobile table 600, the mobile table 600 is enlarged and drawn in order to make the explanation of each configuration easy to understand, but the actual size is small, and the laser light 311 of the laser range finder 310 is a marking plate. It is about the size of 400.

The inclined plate 620 is inclined with respect to the surrounding portion 615 at a predetermined inclination angle θ. A line perpendicular to the base parallel to the floor plane (center line in this figure) 621 is drawn on the inclined plate 621. The mobile table 600 is installed so that the first linear laser beam line 511-2 passes through the center line 621. With the first linear laser beam line 511-2 passing through the center line 621, the distance to the marking plate 400 (that is, the black circle E) is measured using the laser range finder 310. The moving table 600 is moved back and forth on the straight line EF so that this distance becomes a predetermined distance described in the vehicle maintenance manual.

The reason why the inclined plate 620 is inclined at a predetermined inclination angle θ is that the first linear laser beam line 511-2 does not appear when θ = 0 °, and the first when θ = 90 °. The line 511-2 of the linear laser beam appears, but it is not known whether the moving table 600 is installed at a right angle to the straight line EF. That is, the inclination angle θ may be appropriately set in the range of 0 ° <θ <90 °.

FIG. 13 is a diagram for explaining a method of using the mobile table (No. 2) according to the second embodiment. With reference to FIG. 13, the method of S170 “installing the linear laser pointer device on the base of the moving table” of FIG. 1 and S180 “orthogonal to the first linear laser light of the linear laser pointer device”. The method of "determining the point where the second linear laser light and the first linear laser light intersect at the position of the target" will be described.

In FIG. 13, the position of the moving table 600 remains at a predetermined distance from the black circle E by using the laser range finder 300 as described in FIG. The linear laser pointer device 500 is attached to the second attachment portion 640 of the moving table 600. Further, since the marking plate 400 and the laser range finder 300 are not particularly required, they are not drawn in FIG. The above corresponds to the method of S170 “installing the linear laser pointer device on the base of the moving table” in FIG.

Next, the linear laser pointer device 500 attached to the second attachment portion 640 provided inside the open enclosure portion 615 will be described. The first line laser is irradiated to the floor plane from the first irradiation port 510 of the linear laser pointer device 500, and the line 511 of the first linear laser light is drawn on the floor plane. Further, the second line laser is irradiated to the floor plane from the second irradiation port 520, and the line 521 of the second linear laser light is drawn on the floor plane. That is, the ground ink can be produced at the cross line. Further, the line 511 of the first linear laser light and the line 521 of the second linear laser light intersect at a right angle (90 °). This intersection corresponds to the black circle Z in FIG.

In this way, the position of the target is the point where the second linear laser light orthogonal to the first linear laser light of the S180 “linear laser pointer device” of FIG. 1 intersects with the first linear laser light. Can be decided.

The case of determining the black circle Z in FIG. 2 has been described above. Similarly, when determining the black circle Y in FIG. 2, first, a straight line passing through two points (points C and D) on the horizontal plane corresponding to the center of the right front wheel and the center of the right rear wheel of the vehicle 100 is obtained. .. Next, the distance from this straight line to the point C is measured, and the point Y at a predetermined distance is determined. The usage of each part of the target positioning tool is basically the same as the case of determining the black circle Z. The difference is that when the marking plate 400 is placed at the point C, the lower end of the second vertical line 422 of the vertical plate 410 is aligned with the black circle C on the floor plane.

As described above, the method of positioning the target according to the second embodiment (when the black circle Y and the black circle Z in FIG. 2 are determined as the positions where the target is placed) is described in the flowchart of FIG. 1 and the use of each component of FIGS. 8 to 13. The method has been described with reference to the figure.

Similar to the first embodiment, the target positioning tool including the vertical ruler 200, the marking plate 400, and the moving table 600, an external general-purpose point laser pointer device 300, a laser distance meter 310, and By using the linear laser pointer device 500, in the second embodiment, since it is not necessary to use the plumb bob weight, it is not necessary to align the laser beam with one point of the plumb bob weight, and it is horizontal without any trouble. It has the effect that the position of the target on the floor plane can be easily determined.
