The pulling means 13 includes a winding drum 21 that is rotated by a drive source (not shown), and the winding drum 21 and the carriage 14 are releasably connected via a first towing line 22. That is, one end of the first tow line 22 is connected to the winding drum 21, and the other end of the first tow line 22 is provided with a loop portion 22a for switching connection and disconnection with the carriage 14. On the other hand, the trolley 14 and the test vehicle V are releasably coupled via the second tow line 23, and one end of the second tow line 23 is connected to and released from the trolley 14. A loop portion 23a for switching is provided. By the way, a towing hook 24 is generally provided at the front end of the vehicle, and the other end of the second tow line 23 is engaged with and connected to the hook 24 of the test vehicle V.

A pair of insertion holes 26 having a horizontal axis orthogonal to the traveling direction 25 of the carriage 14 are formed on the carriage 14.₁, 26₂Supporting member 27 having a hole and the insertion hole 26₁, 26 ₂ A pair of holes 28 coaxial with₁, 28₂Is fixed so as to extend substantially parallel to the running direction 25. An extending storage groove 30 is formed.

On the opposite side of the support member 27 from the auxiliary support member 29, on the carriage 14, one end of a swinging member 31 formed in the shape of a flat plate having a constant width has a support shaft 32 having a vertical axis. It is rockably supported via. The swinging member 31 has an insertion hole 26. ₁ And hole 28₁Engagement pin 33 that can be inserted into₁A shaft 34 whose base end has an axis parallel to the support shaft 32.₁Is rockably supported by the insertion hole 26₂And hole 28₂Engagement pin 33 that can be inserted into₂The base end of the shaft is 34₁An axis having an axis parallel to₂It is rockably supported by.

As shown in FIG. 2, when the swinging member 31 is in a position substantially parallel to the supporting member 27, both engaging pins 33₁, 33₂Is the insertion hole 26₁, 26₂And hole 28₁, 28 ₂ Is inserted into. On the other hand, the storage groove 30 stores the ends of the first and second tow lines 22 and 23 including the loop portions 22a and 23a. Engagement pin 33₁, 33₂Insertion hole 26₁, 26₂The traction means 13 and the test vehicle V are connected to each other via the carriage 14 by inserting and engaging the portion protruding from the storage groove 30 side.

A separating lever 35 is integrally connected to one end of the swinging member 31, and the swinging member 31 and the separating lever 35 are formed in a substantially L shape as a whole. An abutting portion 35a that abuts a stopper 15 fixedly arranged in the middle of the traveling path 11 when the carriage 14 travels toward the barrier 12 is provided at the tip of the separating lever 35. Thus, when the swinging member 31 is in a position substantially parallel to the supporting member 27 (in the position shown in FIG. 2), the tip of the separating lever 35 can abut the abutting portion 35a with the stopper 15. Therefore, it is projected laterally from the carriage 14.

The trolley 14 is directed toward the barrier 12 while the swinging member 31 is present at the position where the engaging pins 33 ₁ and 33 ₂ are inserted into the loop portions 22 a and 23 a in the storage groove 30 and engaged with each other. When the vehicle travels, the stopper 15 abuts on the contact portion 35a of the separating lever 35 in the middle of the traveling path 11, and the separating lever 35 moves from the loop portions 22a, 23a to the engaging pin 33 as shown in FIG. _The swinging member 31 can be rotated until the ₁ , 33 ₂ are pulled out, and thereby the connection state of the first and second tow lines 22 and 23 with the carriage 14 is released. At this time, since the insertion holes 26 ₁ and 26 ₂ and the holes 28 ₁ and 28 ₂ need to allow the disengagement operation of the engagement pins 33 ₁ and 33 ₂ in accordance with the rocking operation of the rocking member 31, the insertion holes 26 ₁ and 26 ₂ must be inserted. The inner diameters of the holes 26 ₁ and 26 ₂ and the holes 28 ₁ and 28 ₂ are set to be larger than the outer diameters of the engagement pins 3 3 ₁ and 33 ₂ .

Next, the operation of this embodiment will be described. With the loop portions 22a and 23a of the first and second tow lines 22 and 23 housed in the housing groove 30, the swinging member 31 and the supporting member 27 are almost the same. When rotated to the parallel position, the engaging pins 33 ₁ and 33 ₂ are inserted into the insertion holes 26 ₁ and 26 ₂ and the holes 28 ₁ and 28 ₂ , respectively, and also inserted into the loop portions 22 a and 23 a, respectively. It is engaged and the traction means 13 and the test vehicle V are connected via the carriage 14. Then, when the traction means 13 is caused to exert a traction force, the test vehicle V travels on the traveling path 11 toward the barrier 12. At this time, since both the engaging pins 33 ₁ and 33 ₂ are inserted into the insertion holes 26 ₁ and 26 ₂ and the holes 28 ₁ and 28 ₂ , they are supported by the supporting member 27 and the auxiliary supporting member 29. 3 3 _1, 33 ₂ of the two loop portions 22a, the engagement state between 23a is reliably maintained.

When the trolley 14 travels from the barrier 12 to a position on the near side by a certain distance, the stopper 15 is separated and abuts on the abutment portion 35 a of the lever 35, whereby the swinging member 31 is forcibly rotated. As shown in FIG. 5, the engagement state of the loop portions 22a and 23a with the engagement pins 33 ₁ and 33 ₂ is released. Therefore, the connection between the traction means 13 and the carriage 14 and the connection between the carriage 14 and the test vehicle V are released together, and the test vehicle V collides with the barrier 12 by inertial force with the carriage 14 left behind. .

According to such a collision test apparatus, the carriage 14 is provided with a mechanism for switching connection and disconnection of the towing means 13 and the test vehicle V. Therefore, the test vehicle V does not need to be provided with any special means and the carriage 14 can be repeatedly used, which is convenient.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the present invention described in the scope of claims for utility model registration. It is possible to make design changes.

For example, the auxiliary support member 29 can be omitted, and a single engaging pin can be inserted into and engaged with the loop portions 22 a and 23 a of the first and second tow lines 22 and 23. It is also possible to do so.
