BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a target running body for performing a collision test with a collision object for collision avoidance system test, and more particularly, Which is capable of preventing the occurrence of the above-mentioned problems.

Vehicles can cause serious personal injury and property damage in the event of an accident such as convenient transportation or collision. In order to prevent such a vehicle accident, the vehicle is provided with various safety devices such as a bumper for relieving shock and a seat belt.

In recent years, active safety systems have been developed and used to positively prevent such accidents before collision between vehicles. Accordingly, a collision avoidance system for preventing a collision of a vehicle has been actively developed. Such a collision avoidance system can prevent a collision in advance by appropriately controlling the operation of the vehicle when a vehicle is approaching or when various kinds of collision signs are detected, Or to minimize the damage of the collision to a minimum.

Such a collision prevention system is a very easy means to protect people and property, and its reliability is the most important part. Particularly, since the collision prevention system exerts its function in a somewhat extreme situation of an accident between vehicles, there is a limit to the performance of the public by the public. Therefore, You need to make it available.

Therefore, it is very important to develop an appropriate test evaluation system that can test and evaluate such a crash prevention system. In particular, since the driving situation of the vehicle varies in various ways, it is necessary to develop a crash evaluation system for testing and evaluating the crash prevention system in an environment suitable for the actual driving situation.

However, it is also possible to prevent unexpected accidents during the test and evaluation of the collision avoidance system, thereby preventing an increase in the test cost due to injury of the driver and damage to the vehicle during the test between the vehicles mounted with the collision- It is important.

Therefore, a test equipment that can reproduce the situation similar to the actual driving situation and prevent the increase of accident and test cost of the driver is required, and a dummy vehicle similar to the actual vehicle is developed and used for the test.

In many cases, such a dummy vehicle is covered with a vehicle-shaped outer covering for a small target running vehicle so as to reproduce the same operating condition as that of an actual vehicle. However, even in such a case, when the collision object and the dummy vehicle collide with each other, a substantial impact is applied to the target operating body, and the operating body may be damaged.

Therefore, it is necessary to develop a target running body capable of preventing damage during a collision test.

The deformation mode is a mode in which the hinge module 406 rotates and the drive shaft 13 is bent so that the first shaft 402 and the second shaft 404 become biaxial to each other, 12 and the rotary shaft of the actuator 11 are also biaxial.

By the deformation of the hinge module 406 and the deformation of the driving shaft 13, the position of the driving wheel 12 can be changed with respect to the main body 1. [ For example, when the heavy object is placed on the main body 1, the hinge module 406 is deformed, and the position of the main body 1 can be displaced upward, downward, forward, backward, or the like with respect to the driving wheel 12.

Hereinafter, the position restoration module 14 will be described in detail with reference to the drawings.

The position restoration module 14 is connected to the drive shaft 13 so that the drive shaft 13 can maintain the initial mode. And applies a restoring force to the shaft 13.

Specifically, a restoring force is applied so that the driving shaft 13 maintains the initial mode, and a downward force is applied to the main body 1 in a state where the driving wheel 12 is placed on the ground When the restoring force by the position restoring module 14 is overcome, the driving shaft 13 is in the deformation mode, and the restoring force by the position restoring module 14 pushes downward on the main body 1 Or when the pressing force on the body is removed, the driving shaft 13 is in the initial mode due to the restoring force of the position restoring module 14. [

The position restoration module 14 includes a seesection 15 having one end connected to the second shaft 404 and seesaw around a predetermined center axis, A restoring force applying section 16 for applying the restoring force applying section 16 to the seesection 15 and a restoring force applying section 17 for connecting the seesection 15 and the restoring force applying section 16.

First, the seesection 15 will be described.

The seesection 15 includes a seesight beam 310 and a seesaw jig 330. [

Referring to FIG. 17, the seesight beam 310 has a predetermined length in the front-rear direction, and is formed in a predetermined beam shape having a first end at the front and a second end at the rear. The first end of the seesaw beam 310 is disposed on the side of the rotational axis of the drive wheel 12, and the second end of the seesight beam 310 extends rearward. Preferably, two sees beams 310 are provided and symmetrically arranged on both sides of the driving wheel 12 in the rotational axis direction. In addition, a front connecting beam 320 and a rear connecting beam 321 may be provided to connect the seesight beams 310 on both sides to each other.

The seesaw beam 310 includes an intermediate hole 312 formed to penetrate the longitudinally intermediate portion in the horizontal direction, a first side hole 314 formed in the first end portion and penetrating in the horizontal direction, A second side hole 316 formed at an end portion of the first side hole 314 so as to penetrate in the horizontal direction and a second side hole 316 extending in the downward direction at a lower portion between the intermediate hole 312 and the first side hole 314, And has a projection 318. Meanwhile, the seesave beam 310 may have a predetermined installation hole 319 which is formed in a part and penetrates in the horizontal direction.

At this time, the first side hole 314 is located on a path along which the second shaft 404 extends. Accordingly, the second shaft 404 passes through the first side hole 314 in the horizontal direction, and is connected to the driving wheel 12. [ At this time, preferably, the inner diameter of the first side hole 314 may correspond to the diameter of the second shaft 404 or may be larger than the diameter of the second shaft 404.

The second side hole 316 may be connected to a later-described pivotal connection portion 17 and may receive a restoring force from the restoring force applying portion 16 through the pivotal connection portion 17.

13, when the first end portion of the seespun beam 310 is deflected downward by a predetermined angle, the breaking projection 318 is located in contact with the bottom plate 110, and the seespun beam 310 To keep the position of the seesight beam 310 from being maintained.

At this time, the hinge module 406 and the driving shaft 13 have a straight shape when the breaking projection 318 and the bottom plate 110 are in contact with each other. That is, when the breaking projection 318 and the bottom plate 110 are in contact with each other as shown in FIG. 13, the driving shaft 13 maintains the initial mode.

The seesaw jig 330 is formed of a predetermined protruding structure which is positioned on the rear side of the driving wheel 12 and fixed and fixed on the bottom plate 110. In this case, as described above, when two seesight beams 310 are provided, the seesaw jig 330 may be disposed in a space between the two seesights 310.

The seesaw jig 330 is provided with a seesaw shaft 332 and a retaining shaft 334.

The seesaw axis 332 is laterally protruded and inserted into the intermediate hole 312 so that the seesaw beam 310 seesaw around the seesaw axis 332.

The holding shaft 334 may be provided at a lower portion of the seesaw shaft 332 as a shaft for rotating and connecting the restoring force applying unit 16 to be described later. Meanwhile, the holding shaft 334 does not necessarily have to be provided in the see-saw jig 330, and the holding shaft 334 may be provided in a separate member.

14, the seesaw jig 330 includes a seesaw hole 335 and a retaining hole 336 which are horizontally penetrated to insert the seesaw shaft 332 and the retaining shaft 334, respectively, Respectively.

Next, the restoring force application unit 16 will be described with reference to Figs. 19 to 21. Fig.

The restoring force application unit 16 includes a variable beam 350 having a variable length and an elastic unit 360 for applying an elastic force to extend the length of the variable beam 350. The variable beam 350 is configured to push the second end portion of the seesight beam 310 upward by receiving the elastic force by the elastic portion 360. Accordingly, the seesaw beam 310 is rotated about the seesaw axis 332 so that the first end portion is deflected downward. At this time, the variable beam 350 is connected to the seesaw beam 310 through the pivot connection 17, and a restoring force is applied to the seesaw beam 310 through the pivot connection 17.

First, the configuration of the variable beam 350 will be described.

According to one embodiment, the variable beam 350 comprises a front beam 351 and a rear beam 352, which are located at the front and rear in the longitudinal direction, respectively.

The front beam 351 has a front hole 353 and a first support extension 354.

The front hole 353 is located in the front portion of the front beam 351 and is formed to penetrate in the horizontal direction. 14, the holding shaft 334 provided in the searing jig 330 passes through the front hole 353, so that the variable beam 350 is rotated about the holding shaft 334 It is possible.

The first support extension 354 is a component having an outer diameter expanded outward by a predetermined width at an intermediate portion of the front beam 351.

The rear beam 352 has a rear hole 355 and a second support extension 356.

The rear hole 355 is located at the rear portion of the rear beam 352 and is formed so as to pass through in the horizontal direction. The rear hole 355 is rotatably connected to the pivot connection portion 17 described later.

The second support extension 356 is a component having an outer diameter expanded outward by a predetermined width at an intermediate portion of the rear beam 352.

As the front beam 351 and the rear beam 352 are relatively displaced in the longitudinal direction relative to each other, the distance L between the first support extension 354 and the second support extension 356 is variable, The overall length of the beam 350 is variable.

21, an insertion hole 357 penetrating in the longitudinal direction is formed in the rear portion of the front beam 351, and an interpolation beam 358 is formed in the front portion of the rear beam 352. [ So that the first support extension 354 and the second support extension 354 can be inserted into the insertion hole 357 in accordance with the length into which the interpolation beam 358 is inserted into the insertion hole 357, And the total length of the variable beam 350 can be configured to be variable. Of course, an embodiment in which the interiors 357 are formed in the rear beam 352 is also possible, and other configurations are also conceivable.

The elastic part 360 is composed of a coil spring and is wound around the front part of the rear beam 352 and the rear part of the front beam 351. The first supporting part 354 and the second supporting part And the elastic portion 356. [0060] Therefore, when the length of the variable beam 350 is reduced due to the approach of the first support extension 354 and the second support extension 356, the elastic part 360 receives the elastic force.

Next, referring to Fig. 22, the pivotal connection 17 will be described.

The rotary connection unit 17 connects the seesight beam 310 with the variable beam 350 and transmits the restoring force of the restoring force application unit 16 to the seesection 15.

The pivotal connection portion 17 may be configured to include a connection jig 374, a lower beam 373, an upper beam 371, and a connection shaft 372.

The connection jig 374 is located behind the seesaw jig 330 and is fixed on the bottom plate 110.

One end of the lower beam 373 is pivotally connected to the connection jig 374. [ 22, the upper end of the connecting jig 374 is protruded, and the lower beam 373 is disposed on the left and right sides of the upper end of the connecting jig 374, so that the lower beam 373 Is rotatably connected.

One end of the upper beam 371 is pivotally connected to the second end of the seesight beam 310. At this time, the upper beam 371 and the seesaw beam 310 can be pivotally connected through a second side hole 316 provided at a second end of the seesaw beam 310. [ For example, one end of the upper beam 371 may be provided with a predetermined pivotal protrusion functioning as an axis, or a predetermined shaft may be connected thereto.

The connection shaft 372 connects the other end of the upper beam 371 and the other end of the lower beam 373 to each other. Also, the rear hole 355 of the rear beam 352 is connected by the connection shaft 372. For example, as shown in FIG. 22, the lower beam 373 is connected to both sides of the rear beam 352 about the rear beam 352, and the upper beam 372 is connected to the outer side of the lower beam 373. [ (371) can be connected.

Referring to FIGS. 23 and 24, when an upward force is applied to the driving wheel 12, the seesaw part 15, the restoring force applying part 16, The beam 110 rotates about the seesaw axis 332 as indicated by an arrow R and the first end portion rises as indicated by an arrow A and the second end portion descends as indicated by the arrow B. As a result, the angle between the upper beam 371 and the lower beam 373 of the pivot connection portion 370 is reduced, and the connection shaft 372 is moved forward as shown by the arrow C in FIG. Thus, the rear beam 352 is pushed forward, so that the elastic part 360 is compressed, and the elastic part 360 applies an elastic force to resist such compression. This elastic force acts as a restoring force for pushing the connecting shaft 372 backward and consequently returning the driving wheel 12 in the downward direction and returning the shape of the driving shaft 13 to the initial mode. At this time, the variable beam 350 can rotate around the holding shaft 334 by a predetermined angle.

At this time, the drive shaft 13 is deformed in a straight line shape as shown in Fig. 25 and becomes a deformation mode. Thus, the first shaft 402 and the second shaft 404 become biaxial.

Next, the braking module 18 will be described.

14, the braking module 18 includes a braking plate 510 which is fixed to the second shaft 404 and rotates, and a friction portion (not shown) which can impart a frictional force to the braking plate 510 520). The rubbing part 520 is fixed to the side of the seesaw beam 310 and may be installed on the seesight beam 310 by an installation hole 319 formed in the seesaw beam 310.

When the predetermined signal is applied by the user, the friction portion 520 approaches the braking plate 510 and gives a frictional force, so that the rotation of the second shaft 404 and the drive wheel 12 is decelerated Or may be stopped.

26 is a diagram showing the structure of the communication module 4. In Fig.

The communication module 4 is mounted in a mounting space provided in the base frame 102 and is provided so as to exchange signals with an external communication device.

The signal processing unit 620 may be connected to the driving module 3 to process signals received from the outside and to control the operation of the driving module 3.

The antenna unit 610 may have a configuration in which the antenna unit 610 is protruded to the upper portion of the main body 1 and is folded or compressed when the weight unit is placed on the upper portion. Accordingly, breakage of the antenna can be prevented.

Meanwhile, a predetermined sensor device 700 may be provided to detect that a predetermined heavy object is placed on the main body 1.

27 is a view showing a collision test using a target running body according to an embodiment of the present invention. Here, S is the actual vehicle, T is the target vehicle structure, and M is the target running body according to the present invention. A predetermined structure is overlaid on the target running body according to the present invention to construct a target vehicle, and the actual vehicle approaches the target vehicle to perform a collision test.

Particularly, the power is reinforced by the drive module 3 provided in the sub-body 6 and the size thereof is enlarged, so that a situation more similar to the actual collision can be reproduced.

In addition, since the inclined skirt 2 is provided on the outer side of the target running body, when the predetermined impact body and the target running body of the present invention collide with each other, You can go up and down on foot. Therefore, breakage and failure of the target running body can be prevented. That is, even if the target vehicle structure is destroyed due to the collision, the target running body that actually performs the operation is not damaged.

The driving wheel 12 is configured to be displaceable with respect to the main body 1 and the sub body 6 and receives the restoring force by the restoring module so that the colliding body is lifted above the target operating body It is possible to avoid the occurrence of breakage of each member constituting the drive module 3.

In addition, the antenna of the communication module 4 can also be lowered in failure rate by avoiding collapse by collision or collapse when the collision object is over the target cloud.
