Description

Technical Field

[0001] The utility model relates to the technical field of fixed-point testing of helmet protection areas, and particularly relates to a fixed-point testing device for helmet protection areas. Background Technique

[0002] The fixed-point testing device for helmet protection areas includes the testing of the protection performance of helmets when they are impacted. These devices are usually used to simulate specific areas of the helmet that are subjected to forces during collisions or impacts, in order to evaluate the energy absorption, buffering, and protection performance of the helmet. Through these testing devices, we can more accurately understand the performance of the helmet in real collision situations, thereby improving the design and manufacturing of helmets and enhancing the safety and protection performance of helmets.

[0003] Currently, the testing devices available on the market are not convenient for simulating the situation where the helmet is impacted at different angles or directions, and cannot comprehensively evaluate the protection performance of the helmet. A rotating device needs to be added. Thus, to a certain extent, by adjusting the direction and angle of the helmet during testing, the protection performance of the helmet in different directions can be evaluated, and a more comprehensive understanding of the performance of the helmet in different situations can be obtained. Moreover, when testing after adjustment, the helmet may move or shake under the action of force, resulting in inaccurate test results. A clamping and stabilizing device needs to be added. Thus, to a certain extent, it can ensure that the helmet remains in a fixed position during testing, avoid the movement or shaking of the helmet from interfering with the test results, and improve the accuracy of the test. Therefore, it is necessary to design a fixed-point testing device for helmet protection areas. Content of the Utility Model
