Description

Technical Field

[0001] The present invention relates to the technical field of THOR dummies, and in particular to a chest support device for a THOR dummies. Background Art

[0002] The THOR dummy is used in automotive crash tests. Sensor channels are installed in the THOR dummy's head, neck, chest, abdomen, pelvis, legs, and feet. These sensors measure acceleration, angular rate, displacement, force, and bending moment, among other parameters, to detect the dummy's injuries. Compared to traditional crash test dummies, the THOR dummy more closely resembles real-life injury textures, and will be used more extensively in future frontal crash tests.

[0003] The conventional THOR dummy chest support typically consists of two support tubes and long bolts. The tubes are not adjustable in length and are inserted directly into pre-set bolt holes in the THOR dummy. The two tubes are installed at a fixed angle within the dummy. To install the chest support, the dummy is positioned in a specific position. The tubes are then inserted into the mounting holes. The dummy's position is then adjusted to align the tube bolt holes with those on the THOR dummy. The tubes are then secured to the THOR dummy's chest using three bolts.

[0004] Because the angle and distance between the support tubes in the conventional THOR dummy chest support system are not adjustable, installation requires repeated adjustments to the THOR dummy's posture to accurately secure the support tubes. Incorrect positioning can affect chest support installation and damage the THOR dummy's designated bolt mounting holes. Furthermore, the dummy's posture is difficult to adjust during daily use, making conventional THOR dummy chest support systems difficult to install. Summary of the Invention

[0022] Among them, the slider 2 is slidably set at the upper end of the load-bearing guide rail 3, the second support tube 6 is horizontally fixed at the lower end of the load-bearing guide rail 3, and the first support tube 1 is connected to the slider 2 by rotating up and down; bolts are installed in the bolt holes reserved at the chest and pubic bone of the THOR dummy, the first support tube 1 is provided with a first through hole for connecting with the bolt at the chest, and the second support tube 6 is provided with a second through hole for connecting with the bolt at the pubic bone, and the two support tubes are connected on the same side inside the THOR dummy body.

[0023] The existing THOR dummy chest support device is a monolithic device. During use, the Thor dummy's posture must be repeatedly adjusted to ensure accurate support and fixation. Incorrect positioning can lead to failed installation of the chest support device and even damage to the pre-set bolt mounting holes on the Thor dummy. Damaged mounting holes require time-consuming disassembly of the dummy to replace. Adjusting the dummy's specific posture is difficult, making chest support installation difficult. Installation of the chest support requires high technical skills, making it difficult for ordinary operators. The disclosed THOR dummy chest support device utilizes a slide rail and a slider 2. The slider 2 slides up and down the rail, driving a first support tube 1 up and down, adjusting the distance between the first support tube 1 and the second support tube 6 to prevent damage to the pre-set bolt holes when the chest support device is inserted into the dummy. Furthermore, the first support tube 1 rotates about a fixed axis to adjust the angle between the first support tube 1 and the second support tube 6. This eliminates the need to adjust the THOR dummy to a specific posture when installing the THOR dummy chest support device, reducing installation complexity and avoiding damage to the pre-set holes within the THOR dummy. The installation is simple and time-saving.

[0024] Among them, two first ear plates are arranged in parallel and spaced apart on the slider 2, and a second ear plate is arranged on the first support tube 1, and the second ear plate is inserted between the two first ear plates; relative reserved holes are arranged on the first ear plate and the second ear plate; a fixed axis passing through the first ear plate and the second ear plate is arranged in the reserved hole, and the first support tube 1 rotates around the fixed axis to change the angle between the first support tube and the second support tube.

[0025] Among them, the lower end of the load-bearing guide rail 3 is fixedly connected with a reinforcing rod 4 and a connecting member 5; the connecting member 5 is extended toward the lower end of the load-bearing guide rail 3; the second support tube 6 is fixedly connected to the reinforcing rod 4 and the connecting member 5 at the same time, and the reinforcement rod 4 and the connecting member 5 are provided to make the connection of the second support tube 6 more stable.

[0026] Among them, sliding grooves are set on both sides of the load-bearing guide rail 3, and protrusions are set in the sliding grooves; the slider is set with a groove, and the inner side of the groove matches the sliding grooves on both sides of the load-bearing guide rail; the load-bearing guide rail 3 is provided with multiple positioning holes, and a safety pin 7 is installed in the positioning hole. The safety pin 7 passes through the load-bearing guide rail 3 and the slider 2. The safety pin 7 can limit the sliding of the slider 2 and fix the slider 2.

[0027] Among them, the lower end of the reinforcing rod 4 is provided with a through hole connected to the second support tube 6; the lower end of the connecting member 5 is provided with three third through holes arranged in a triangle, the third through hole located at the top of the triangle is detachably fixedly connected to the load-bearing guide rail 3, and the two third through holes located at the bottom of the triangle are detachably fixedly connected to the second support tube 6; the tops of the reinforcing rod 4 and the connecting member 5 are provided with relative fourth through holes, and bolts are provided in the fourth through holes, and the bolts pass through the load-bearing guide rail 3.

[0028] Among them, the top of the reinforcing rod 4 is provided with an integrally formed, tilted fixing portion. The tilted reinforcing rod 4 can form a triangle with the load-bearing guide rail 3 to increase stability.

[0029] The width of the connecting member 5 gradually increases from top to bottom.

[0030] The working process of the present invention is: first connect the load-bearing guide rail 3, the reinforcing rod 4, the connecting piece 5, and the second support tube through bolts and the reserved through holes; then connect the first support tube 1 and the slider 2 through a fixing pin, and check whether the first support tube 2 can rotate normally; connect the slider 2 to the load-bearing guide rail 3, and check whether the slider 2 can slide normally; according to the different postures of the THOR dummy, adjust the spacing and angle between the two support tubes of the chest support device, connect the reserved through holes of the chest support device with the corresponding bolt holes in the THOR dummy body through bolts, adjust the dummy posture to a suitable position, and then insert the safety pin to fix the dummy posture. The installation of the THOR dummy chest support device described in the present invention is completed.

[0031] In summary, an embodiment of the present invention provides a THOR dummy chest support device that uses a slide rail and a slider. The slider can slide up and down on the slide rail, and the slider drives the first support tube to move up and down, adjusting the distance between the first support tube and the second support tube, so that the chest support device avoids damage to the reserved bolt hole when inserted into the dummy body; and the first support tube can adjust the angle between the first support tube and the second support tube by rotating around the fixed axis. When installing the THOR dummy chest support device, there is no need to adjust the THOR dummy to a specific posture, which reduces the difficulty during installation, avoids damage to the reserved holes inside the THOR dummy, and is simple to install and saves time.
