Description

Technical Field

[0001] The utility model relates to the field of automobile safety detection, in particular to a device for manufacturing the buttocks skin of a SID-IIs small side impact dummy. Background Technique

[0002] As is well known, side collision accidents are very common in general traffic accidents. Therefore, the side occupant protection performance of vehicles is crucial for the development of automobile safety. Since the 1970s, countries such as the United States have begun to research automobile side collision test technologies. In 1996, the FMVSS214 side collision occupant protection regulation was introduced. Subsequently, various countries have successively formulated their own side collision safety regulations. The dummies used in early tests were all male at the 50th percentile, such as the Hybrid III 50th percentile dummy.

[0003] With the development of side collision research, the new FMVSS214 began to require the use of SID-IIs side collision dummies representing the body types of women and teenagers, so as to evaluate the side protection performance of vehicles for small-sized people. Nowadays, SID-IIs dummies are increasingly widely used and are indispensable for evaluating automobile collision safety.

[0004] The dummy used for collision tests needs to be close to the real human body state. Therefore, in addition to the skeleton structure, the skin should also have strong bionic characteristics. To achieve this performance, the dummy skin uses bionic materials and fits the external shape structure of real people.

[0005] Among them, the buttocks skin of the dummy has a relatively complex shape structure. In addition to the external shape structure dimensions being approximately the same as those of real people, specific-shaped cavities must be left inside for wrapping the pelvic bone and assembling with other components. CN212472157U discloses a buttocks skin mold for a Hybrid III 50th percentile dummy. The buttocks skin mold involved in this patent has few component structures, and the shape of a single structure is complex, making it difficult to accurately process, and the dimensional accuracy of the finished skin is poor; moreover, the pouring gate is at the highest point on the rear side of the buttocks, and the material is injected from a high place during the pouring process, which is prone to local filling deficiencies or unevenness caused by gravity and the flow path, affecting the skin forming quality. In order to ensure the production quality of the buttocks skin of the SID-IIs dummy, we need to independently develop a manufacturing device to make the skin form evenly, reduce air bubbles and cracks, and at the same time fit the required structural dimensions and facilitate demolding.
