Description

Table device for dummy inspection and inspection device

[0001] The present invention relates to a table device for dummy inspection and an inspection device.

[0002] Conventionally, a human dummy (TD: Test Dummy) used as a substitute for a human in a vehicle collision test or the like has a structure mainly surrounded by a fleshy part and a skin part made of synthetic resin or the like around the skeleton part. This human dummy needs to be configured to approximate the deformation characteristics and the like of the human body as closely as possible with respect to impacts and loads. For this reason, the human dummy is configured to satisfy a predetermined quality that exhibits physical properties similar to those of the human body. Then, the manufactured human dummy is inspected by checking whether the head, chest, waist, etc. conform to a predetermined standard, for example, using a dummy verification test device (see Patent Document 1).

[0003] That is, in the above dummy verification test device, the legs of the human dummy are attached and fixed to a dummy mounting base, and the impactor is lifted and then freely dropped. Then, the impact speed of the impactor on the legs is measured by a sensor unit, and inspection is performed. In this dummy verification test device, the position of the impact point on the legs of the human dummy is adjusted by raising and lowering the dummy mounting base with a lifting device.

[0004] Japanese Patent No. 4105988

[0005] However, in the dummy verification test device disclosed in Patent Document 1 above, the position adjustment of the impact point on the legs of the human dummy is only in the vertical direction by raising and lowering. For this reason, there is a problem that the position adjustment range of the impact point is narrow and the versatility to other parts of the human dummy is low. In recent years, there has been an increasing need to provide a plurality of sensor units inside the human dummy and to inspect whether the structures of the skeleton part, fleshy part, skin part, etc. at a predetermined impact point satisfy the required standards.

[0006] In such cases, the human dummy must first be manually placed on the dummy mounting stand. Then, the dummy must be moved precisely so that the point of impact on the human dummy aligns with a predetermined collision point with the impactor, and the position of the point of impact must be adjusted while checking each time. This presents a problem in that the position adjustment process is extremely complicated.

[0007] The present invention has been made in view of the above circumstances, and aims to provide a dummy inspection table device and inspection device that can easily adjust the position of the collision point of a human body dummy while widening the range of adjustment of the position of the collision point of the human body dummy to the collision point, thereby increasing versatility.

[0008] The dummy inspection table device according to the present invention includes a dummy mounting table positioned above the floor surface on which a dummy to be inspected is placed. It also includes a first drive mechanism positioned between the floor surface and the dummy mounting table to move the dummy mounting table up and down. It also includes a second drive mechanism positioned between the floor surface and the dummy mounting table to slide the dummy mounting table along a first horizontal direction relative to the floor surface. Furthermore, it includes a third drive mechanism positioned between the floor surface and the dummy mounting table to slide the dummy mounting table along a second horizontal direction perpendicular to the first direction relative to the floor surface.

[0009] In one embodiment of the present invention, the first drive mechanism includes a lifting mechanism installed between the floor surface and the dummy mounting platform, and a first drive unit that moves the lifting mechanism up and down. The second drive mechanism includes a first frame portion provided above the lifting mechanism and moving up and down relative to the floor surface, and a second drive unit that slides a second frame portion, which is provided so as to be slidable in the first direction relative to the first frame portion, along the first direction. The third drive mechanism includes the second frame portion and a third drive unit that slides the dummy mounting platform along the second direction.

[0010] In another embodiment of the present invention, the second drive unit includes a first wheel mechanism that rolls along a pair of parallel first rail units provided on the first frame, a first ball screw mechanism provided parallel to the first rail units, and a first screw drive motor that drives the first ball screw mechanism. The third drive unit includes a second wheel mechanism that rolls along a pair of parallel second rail units provided on the second frame so as to be perpendicular to the first rail units, a second ball screw mechanism provided parallel to the second rail units, and a second screw drive motor that drives the second ball screw mechanism.

[0011] In yet another embodiment of the present invention, a control unit is further provided that controls the operation of the first drive unit, the second drive unit, and the third drive unit to move the dummy mounting table in three axes.

[0012] The inspection apparatus according to the present invention comprises the dummy inspection table apparatus described above, a support frame portion erected from the floor surface, and a support member provided on the support frame portion. It also comprises a plurality of wire members, one end of which is connected to the support member, impactors attached to the other ends of the plurality of wire members and suspended from the support member via the plurality of wire members, and a lifting mechanism for raising the impactors to a predetermined height so as to be able to swing like a pendulum.

[0013] One embodiment of the present invention further comprises a position measuring means capable of measuring the position of the point of collision between the human body dummy, which is placed on the dummy mounting platform, and the impactor.

[0014] In another embodiment of the present invention, the control unit moves the dummy mounting platform to align the position of the collision point of the human body dummy with the collision point with the impactor, based on position information from the position measuring means.

[0015] According to the present invention, the range of position adjustment for the collision point of the human body dummy is wide, increasing versatility, while also making it easy to adjust the position of the collision point of the human body dummy.

This is a schematic rear view of the dummy inspection table device. This is a schematic side view of the dummy inspection table device. This is a schematic top view of the dummy inspection table device with a portion of it transparent.

[0017] Hereinafter, with reference to the attached drawings, a dummy inspection table device and an inspection device according to embodiments of the present invention will be described in detail. However, the following embodiments are not intended to limit the invention according to each claim, and not all combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0018] Furthermore, in the following embodiments, identical or equivalent components are denoted by the same reference numerals, and redundant descriptions are omitted. Also, in the embodiments, the arrangement, scale, and dimensions of each component may be exaggerated or reduced to not match the actual ones, and some components may be omitted from the description.

[0019] Figure 1 is a schematic side view showing an inspection apparatus equipped with a dummy inspection table device according to one embodiment of the present invention. Figure 2 is a schematic rear view showing the dummy inspection table device. Figure 3 is a schematic side view showing the dummy inspection table device. Figure 4 is a schematic top view showing the dummy inspection table device with a portion of it transparent.

[0020] As shown in Figure 1, the inspection device 1 includes, for example, a dummy inspection table device 10 on which a human body dummy 90 to be inspected is placed, and a base plate 2 on the floor surface 1a on which the dummy inspection table device 10 is installed and fixed. The inspection device 1 also includes a plurality of support frame sections 3 erected parallel to each other upward from the base plate 2, and an impactor support section 5 provided near the bridge section connecting the upper ends of these support frame sections 3, which serves as a support member for supporting an impactor 4, which is a shock element.

[0021] Furthermore, the inspection device 1 includes a plurality of wire members 7, one end of which is pivotably connected to the impactor support section 5, and to which an impactor 4 is attached at the other end. In addition, the inspection device 1 includes an impactor 4 suspended from the impactor support section 5 via these plurality of wire members 7, and a lifting mechanism 6 that lifts the impactor 4 to a predetermined height in a pendulum-like motion.

[0022] The lifting mechanism 6 is provided, for example, on the lower end side of the impactor support portion 5. The lifting mechanism 6 has a rotating device 6a that rotates a lifting frame 6b, to which a detachable electromagnet mechanism 6c is connected to the impactor 4, in the direction indicated by arrow A in Figure 1, thereby lifting the impactor 4 together with the electromagnet mechanism 6c to a predetermined height in the direction indicated by arrow B in Figure 1.

[0023] After being raised to a predetermined height by the lifting mechanism 6, the impactor 4 collides at the point of impact 99 of the sensor-equipped human body dummy 90 placed on the dummy mounting platform 40, so as to impart a predetermined collision speed and impact force by blocking the magnetic force of the electromagnet mechanism 6c.

[0024] The collision points of the human body dummy 90 can be arbitrarily set as inspection points that require inspection, such as predetermined positions on the left and right of the head, predetermined positions on the left and right of the chest, and predetermined positions on the left and right of the abdomen. The inspection device 1 checks whether the measured values ​​at the collision points of the human body dummy 90 meet predetermined standard values. This allows the inspection device 1 to determine whether the skeletal parts, muscle parts, skin parts, etc. at the collision points of the human body dummy 90 meet predetermined quality standards.

[0025] Furthermore, the inspection device 1 includes a laser positioning device 80, which is a position measuring means for measuring the position of the point of collision between the human body dummy 90, placed on the dummy mounting table 40 of the dummy inspection table device 10, and the impactor 4. The inspection device 1 also includes a control panel (control unit) 70 for controlling the operation of the inspection device 1, including the dummy inspection table device 10, the lifting mechanism 6, and the laser positioning device 80.

[0026] The dummy inspection table device 10 and the support frame section 3 are installed on the floor surface 1a via the base plate 2, but are not limited to this, and may be installed directly on the floor surface 1a. Also, the control panel 70 is positioned at a predetermined location on one of the support frame sections 3, but are not limited to this.

[0027] Furthermore, the laser positioning device 80 is positioned on a mounting table 80b supported by a mounting frame 80a installed on the floor surface 1a, but is not limited to this. Although not shown in the figures, a dummy receiving plate for receiving a human body dummy 90 may be installed on the back side of the dummy mounting platform 40 of the dummy inspection table device 10. In the following description, the front-to-back direction of the inspection device 1 will be referred to as the Y direction, the left-to-right direction as the X direction, and the up-and-down direction as the Z direction.

[0028] As shown in Figures 2 to 4, the dummy inspection table device 10 is positioned above the floor surface 1a and includes a dummy platform 40 on which a human body dummy 90 is placed. The dummy inspection table device 10 also includes a first drive mechanism 11, a second drive mechanism 20, and a third drive mechanism 30. The first drive mechanism 11 is positioned between the floor surface 1a and the dummy platform 40 and moves the dummy platform 40 up and down.

[0029] The second drive mechanism 20 is positioned between the floor surface 1a and the dummy mounting platform 40 and slides the dummy mounting platform 40 along the horizontal Y direction (first direction) relative to the floor surface 1a. The third drive mechanism 30 is positioned between the floor surface 1a and the dummy mounting platform 40 and slides the dummy mounting platform 40 along the horizontal X direction (second direction) perpendicular to the Y direction relative to the floor surface 1a.

[0030] In the dummy inspection table device 10 of this embodiment, the first to third drive mechanisms 11, 20, and 30 are arranged between the floor surface 1a and the dummy mounting table 40 in the Z-direction from the floor surface 1a toward the dummy mounting table 40, but this is not limited to this arrangement. The arrangement order of the first to third drive mechanisms 11, 20, and 30 in the Z-direction between the floor surface 1a and the dummy mounting table 40 can be set arbitrarily.

[0031] The first drive mechanism 11 includes a lifting device 11a, which is a lifting mechanism, and a hydraulic cylinder mechanism (first drive unit) 12 that moves the lifting device 11a up and down. The lifting device 11a includes, for example, a base frame 13 installed on a base plate 2 on the floor surface 1a, an upper frame 14 to which the first frame portion 20a is attached, and a pantograph-type X-arm 15 that connects the base frame 13 and the upper frame 14. The hydraulic cylinder mechanism 12 extends and retracts the X-arm 15.

[0032] The second drive mechanism 20 includes a first frame section 20a and a second drive section, a Y-direction slide drive section 21. The first frame section 20a is provided above the lifting device 11a and connected to the upper frame 14, and moves up and down in the Z direction relative to the floor surface 1a by the lifting operation of the lifting device 11a. The Y-direction slide drive section 21 slides, for example, the second frame section 30a, which is provided so as to be slidable in the horizontal Y direction (first direction) relative to the first frame section 20a, in the Y direction. As a result, the dummy mounting platform 40 slides in the Y direction relative to the floor surface 1a.

[0033] The third drive mechanism 30 includes a second frame portion 30a and a third drive portion, the X-direction slide drive portion 31. The first frame portion 20a and the second frame portion 30a are formed, for example, in a rectangular frame shape when viewed from above. The dummy mounting table 40 is formed, for example, in a rectangular plate shape when viewed from above. The X-direction slide drive portion 31 slides the dummy mounting table 40, which is provided above the second frame portion 30a, in the horizontal X direction (second direction) perpendicular to the Y direction relative to the second frame portion 30a. As a result, the dummy mounting table 40 slides in the X direction relative to the floor surface 1a.

[0034] The Y-direction slide drive unit 21 comprises a plurality of first wheel mechanisms 23, a first ball screw mechanism 24, and a first screw drive motor 25. The plurality of first wheel mechanisms 23 roll along a pair of parallel first rail units 22 provided on the upper part of the first frame portion 20a along the Y direction. The first ball screw mechanism 24 is provided parallel to the first rail unit 22. The first screw drive motor 25 drives the first ball screw mechanism 24 via a drive belt 26.

[0035] The X-direction slide drive unit 31 comprises a plurality of second wheel mechanisms 33, a second ball screw mechanism 34, and a second screw drive motor 35. The plurality of second wheel mechanisms 33 roll along a pair of parallel second rail units 32 provided on the upper part of the second frame portion 30a along the X direction. The second ball screw mechanism 34 is provided parallel to the second rail unit 32. The second screw drive motor 35 drives the second ball screw mechanism 34 via a drive belt 36.

[0036] In this embodiment, the first rail unit 22 and the second rail unit 32 are each formed, for example, with a V-shaped cross-section. Therefore, the first wheel mechanism 23 and the second wheel mechanism 33 each include multiple sets of wheel units, each in which pairs of wheels are arranged in an inverted V-shape so that the wheels contact the inclined surfaces of the first rail unit 22 and the second rail unit 32.

[0037] In this way, it becomes possible to shorten the distance between, for example, the first frame portion 20a and the second frame portion 30a, and between the second frame portion 30a and the dummy mounting table 40. As a result, the overall height of the dummy inspection table device 10 can be made lower compared to one in which the wheels are arranged vertically. Note that the Y-direction slide drive unit 21 and the X-direction slide drive unit 31 are not limited to the above configuration, and various known configurations can be adopted as long as they can slide the dummy mounting table 40 in the Y direction and the dummy mounting table 40 in the X direction, respectively.

[0038] Furthermore, the hydraulic cylinder mechanism 12, the Y-direction slide drive unit 21, and the X-direction slide drive unit 31 can each be operated individually, for example, by the user of the dummy inspection table device 10 inputting operations into the control panel 70. In this way, the dummy inspection table device 10 has the function of moving the dummy mounting table 40 in three axes by controlling the operation of the hydraulic cylinder mechanism 12, the Y-direction slide drive unit 21, and the X-direction slide drive unit 31 via the control panel 70.

[0039] In the inspection of the human dummy 90 using the inspection device 1, first, the impactor 4 is lifted by the lifting mechanism 6, and then the human dummy 90 is roughly placed on the dummy mounting table 40 of the dummy inspection table device 10 so as to maintain the required posture, and so as to align the collision point, which is the inspection area, with the collision point 99. Next, the position of the collision point of the human dummy 90 is confirmed by positioning using the laser positioning device 80.

[0040] Then, based on the position information from the laser positioning device 80, the hydraulic cylinder mechanism 12, the Y-direction slide drive unit 21, and the X-direction slide drive unit 31 are operated via the control panel 70. This causes the dummy mounting platform 40 to be moved in three axes (up, down, forward, backward, left, and right) so that the point of impact on the human body dummy 90 aligns with the collision point 99, thereby precisely adjusting the position of the point of impact on the human body dummy 90 and aligning it with the collision point 99. After that, the impactor 4 is operated to collide with the point of impact on the human body dummy 90 at the collision point 99, and various data are acquired by the sensors inside the human body dummy 90, thus ending the inspection.

[0041] This makes it possible to adjust the position of the collision point of the human body dummy 90 on the dummy mounting table 40 with much greater accuracy and in a shorter time compared to repeatedly making fine adjustments to the position of the collision point manually. Therefore, the inspection device 1 using the dummy inspection table device 10 makes it possible to improve inspection accuracy and shorten inspection time.

[0042] Furthermore, the dummy inspection table device 10 of the inspection device 1 can also be configured to automatically operate the hydraulic cylinder mechanism 12, the Y-direction slide drive unit 21, and the X-direction slide drive unit 31 by automatic control by a control panel 70 based on position information from a laser positioning device 80. This makes it possible to automatically move the dummy mounting table 40 in three axes to align the collision point of the human body dummy 90 with the collision point 99.

[0043] As described above, the embodiments of the present invention have been explained. However, these embodiments are presented as examples and are not intended to limit the scope of the invention. This novel embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalent scope thereof.

[0044] For example, in the above embodiment, the dummy mounting table 40 of the dummy inspection table device 10 is configured to be electrically moved in three axes by the hydraulic cylinder mechanism 12 of the lifting device 11a, the Y-direction slide drive unit 21, and the X-direction slide drive unit 31. However, the present invention is not limited to this, and a configuration in which at least a part of these is manually operated or a configuration in which at least a part of these is omitted can also be adopted.

[0045] In addition, although the configuration is such that the laser displacement measuring device 80 measures the collision point of the human dummy 90, the present invention is not limited to this as long as the position of the measurement point can be measured. Furthermore, since the support frame portion 3, the impactor support portion 5, the hoisting mechanism 6, and the plurality of wire members 7 of the inspection device 1 are examples, the present invention is not limited to this, and the inspection device 1 can adopt various configurations as long as it uses the dummy inspection table device 10.
