[0002] Due to the danger of the crash test, automobile safety crash models, i.e. dummies, are used as test tools at home and abroad. HⅢ50th and HⅢ95th dummies are often used in crash tests. However, some crash tests only need to balance the weight of the whole vehicle during the test process. , there is no need to collect a large amo...

Method used

Between the upper arm 3 and the upper trunk assembly 6, between the upper arm 3 and the lower arm 4, between the thigh 8 and the shank 9, the joint between the shank 9 and the foot 10 all passes through the shaft shoulder after heat treatment Screws 16 are connected, and nylon pads 15 are arranged between the two joints, which ensures the adjustability of the rotation tightness of each joint of the dummy body.

Abstract

A specification-adjustable dummy used for car crash testing comprises a skull, a neck, upper arms, lower arms, hands, a jacketed upper body assembly, a butt, thighs, shanks and feet, and balancing weights are arranged on end covers of the skull, the neck, the upper arms, the lower arms, the hands, the jacketed upper body assembly, the butt, the thighs, the shanks and the feet. The specification-adjustable dummy used for car crash testing has the advantages that a structure is simple, manufacturing cost is low and testing cost is lowered by means of substituting dummies with HIII50th balancing weights and HIII95th balancing weights in vehicle testing; an application range is wide, specifications are adjustable, and applicability to tests in different specifications is achieved by means of balancing weight adjustment; mounting and dismounting are facilitated, and since no skins are arranged on the arms and the legs, mounting, dismounting and transportation of the dummy are more convenient; test can be implemented during dynamic response in a testing process; the degree of rotating tightness in each dummy body joint part is highly adjustable, the dummy can be fixed by a safety belt, and the safety belt and other interior trims in a car cannot be damaged during crashing.

Example Embodiment

[0016] The present invention will be further described below with reference to the drawings and embodiments.

[0017] Reference figure 1 , figure 2 with image 3 This embodiment includes skull 1, neck 2, upper arm 3, lower arm 4, hand 5, upper torso assembly 6 with jacket, buttocks 7, thigh 8, calf 9 and foot 10, said skull 1, The neck 2, the upper arm 3, the lower arm 4, the hand 5, the upper torso assembly 6 with jacket, the buttocks 7, the thigh 8, the calf 9 and the foot 10 are provided with counterweights 11 on the mounting end covers.

[0018] The skull 1, neck 2, upper arm 3, lower arm 4, hand 5, upper torso assembly with jacket 6, buttocks 7, thigh 8, calf 9 and foot 10 are provided with threaded holes 12 on the mounting end caps, The counterweight 11 is provided with a through hole 11-1, and the counterweight 11 is fixedly connected to the threaded hole 12 on the end cap through the screw 13; the size of the through hole 11-1 of the counterweight is adapted to the screw 13, and The counterweight 11 and the screw 13 are fixed by a nut 14, and a counterweight 11 of different weights is added to adjust the weight of various parts of the dummy's body, so as to change the overall weight of the dummy, thereby achieving the purpose of changing the specifications of the dummy .

[0019] The joints between the upper arm 3 and the upper torso assembly 6, the upper arm 3 and the lower arm 4, the thigh 8 and the calf 9, and the calf 9 and the foot 10 are all connected by heat-treated shoulder screws 16 , There is a nylon pad 15 between the two joints to ensure the adjustability of the rotation of the joints of the dummy body.

[0020] The upper torso assembly 6 with jacket, the hip 7, the joint between the upper arm 3 and the lower arm 4, and the joint between the thigh 8 and the calf 9 are all equipped with dummy skin, and the dummy skin is made of polyurethane material.

[0021] Skin made of polyurethane materials such as knee pads, pads 17, joint pads, and shock-absorbing gaskets. At the same time, the upper torso assembly 6 and buttocks 7 are also covered with skin, so that the dummy can be fixed with a seat belt and in the collision process It will not damage the seat belt and other interiors in the car.

[0022] The framework of each part of the invention is integrally welded with a steel structure, and the strength of the framework can fully meet the strength requirements of automobile collision.
