Description

Crash test dummy loading and unloading device

technical field

The utility model relates to the field of automobiles, in particular to a loading and unloading device for a collision test dummy.

Background technique

In the current automobile crash test, when placing the test dummy, a lifting device is used to connect the pull hook through a steel cable, and the dummy is lifted by hooking the pull ring on the top of the dummy head by the pull hook to move the dummy. At this time, the dummy being hoisted is in an upright state, which will occupy a large hoisting space, and the hoisting device has less constraints on the dummy, which will cause the dummy to swing during the handling process, requiring the operator to support it. In addition, when the dummy moves to the door of the test vehicle, the hoisting device cannot limit and adjust the posture of the dummy, but due to the size of the door, it is impossible to use the dummy for the test. The dummy is pushed directly onto the seat of the vehicle, and the tester needs to carry the dummy into the vehicle. Since the dummy used in the test is of western size and heavy, it is difficult for the test personnel to move the test dummy, which prolongs the test preparation time and affects the efficiency of the test preparation. At the same time, after the test is completed, when the dummy is removed and put into the dummy storage room, multiple testers need to work together to remove the test dummy from the vehicle smoothly, which increases the labor intensity of the operators.

As shown in Figure 1 and Figure 4, in order to further adjust the posture of the dummy after hoisting, a control mechanism 7 is provided on the front end of the base cross arm 3 (the end of the base cross arm 3 connected to the dummy fixing mechanism 5), At the rear end of the base cross arm 3 (the end of the base cross arm 3 hinged with the base vertical arm 2), a posture adjustment mechanism 6 is provided, and the dummy fixing mechanism 5 is fixed on the control mechanism 7, and the posture adjustment mechanism 6 acts on it. In the control mechanism 7 to adjust the posture of the dummy fixing mechanism 5; specifically, the control mechanism 7 includes a control rod 71 and a pull ring 72 for connecting with the posture adjustment mechanism 6, and the middle part of the control rod 71 is hinged on the second rotating shaft 73. On the cross arm 3 of the base, the dummy fixing mechanism 5 is fixed on the bottom of the control rod 71 , and the pull ring 72 is arranged on the top of the control rod 71 .

Please refer to Fig. 1 and shown in Fig. 3 and Fig. 4, the attitude adjustment mechanism 6 includes a horizontal shaft 61 and a rotating handle 62, the base cross arm 3 is hinged on the upper end of the base vertical arm 2 through the horizontal shaft 61, and the rotating handle 62 is the same as The shaft is fixedly connected to one end of the horizontal shaft 61, and the draw ring 72 of the control mechanism 7 is connected with the horizontal shaft 61 by a rope 10 (such as a steel cable); Wrapped on the horizontal axis 61, since the rope 10 is tightened, the control rod 71 is pulled to rotate around the second rotating shaft 73, so as to adjust the inclination angle of the dummy fixing mechanism 5, so that the fixed dummy can have a more suitable position, so that it can be inserted through the door into a seat with a relatively narrow structural space. In the present utility model, the base cross arm 3 is a hollow structure, and the rope 10 can pass through the base cross arm 3 , so that the structure of the crash test dummy device of the present utility model can be simplified.

Please continue to refer to Fig. 1 and in combination with Fig. 3 and Fig. 4, in order to prevent the horizontal shaft 61 from being rotated by the reaction force of the rope 10, the part of the rope 10 that is wound is loosened, resulting in the failure of the posture adjustment of the dummy; therefore, the posture Adjustment mechanism 6 also includes angle locking mechanism 63, and angle locking mechanism 63 is located at the other end of horizontal axis 61, and angle locking mechanism 63 includes locking gear 631, locking block 632, the 3rd rotating shaft 633 and locking stop position. Block 636, the locking gear 631 is coaxially fixedly connected to the horizontal shaft 61, the middle part of the locking block 632 is connected to the base cross arm 3 through the third rotating shaft 633, and one end of the locking block 632 is clamped on the locking gear 631 In the tooth groove, the locking stop block 636 is fixed on the cross arm 3 of the base, and is positioned at the side of the other end of the locking block 632. When the dummy pulls the rope 10 back by gravity, the reaction force of the rope 10 will make The horizontal shaft 61 has a reverse rotation tendency (opposite to the rotation direction of the horizontal shaft 61 when the rope 10 is wound), so that the locking gear 631 pushes back the locking block 632 so that it has a tendency to rotate around the third rotating shaft 633. At this time, The locking block 632 leans against the locking block 636, and the locking block 636 will block the locking block 632 to limit the rotation of the locking block 632 around the third rotating shaft 633, thus limiting the reverse rotation of the horizontal axis 61. Rotate to ensure that the dummy is always in the adjusted posture.
