Description
Technical Field
[0001] This utility model relates to the field of safety helmet impact model technology, specifically a safety helmet impact model structure for scientific and educational purposes. Background Technology
[0002] In industrial production, construction, and other fields, safety helmets are essential personal protective equipment. Their core function is to effectively reduce head injuries from external impacts and ensure the wearer's safety through the rigid support of the helmet body and the deformation absorption of the cushioning layer. Therefore, in educational settings such as safety education and vocational skills training, it is crucial to enable learners to intuitively understand the protective principles of safety helmets, especially the energy absorption mechanism of the cushioning layer during impact.
[0003] Based on the above, the inventors have discovered the following problems: In current science and education scenarios such as safety education and vocational skills training, there is a great deal of reliance on pictures, videos or static models, which cannot show the dynamic deformation of the internal buffer layer of the safety helmet during the impact process, such as the dent and compression. Learners find it difficult to intuitively perceive the role of the buffer layer.
[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a scientific and educational safety helmet impact model structure in order to achieve a more practical value. Utility Model Content
[0005] The purpose of this invention is to provide a safety helmet impact model structure for scientific and educational use, so as to solve the problems mentioned in the background art.
[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0007] A safety helmet impact model structure for scientific and educational use includes a placement component, an impact component, and a safety helmet model body. The impact component is disposed inside the upper part of the placement component, and the safety helmet model body is disposed inside the placement component. The placement component is used to place the safety helmet model body to be impacted, and the impact component is used to perform an impact operation on the safety helmet model body. The safety helmet model body is used to demonstrate the deformation effect of the buffer layer upon impact. The safety helmet model body includes a helmet body, an internal buffer layer, an internal liner, and a brim connected to the outer edge of the helmet body. The helmet body is made of transparent polycarbonate material, and the buffer layer is made of EPE pearl cotton material.
[0008] Furthermore, the placement component includes a box, a first through hole is provided inside the bottom of the box, a base is installed at the bottom of the box, a second through hole is provided at the upper end of the base, a support rod is slidably connected between the first through hole and the second through hole, a support seat is installed at the upper end of the support rod, the safety helmet model is placed on the support seat, and the outer wall of the support seat is in contact with the inner wall of the safety helmet model.
[0009] The beneficial effects of adopting the above-mentioned further solution are that the outer wall of the support base fits into the inner wall of the helmet model, which can firmly fix the helmet model in the preset position, so that the top of the helmet faces the impact head, avoiding the model from shaking or shifting during the impact, ensuring that the impact force always acts on the center of the helmet top, and ensuring the consistency of the demonstration effect; the shape of the support base fits into the inner wall of the helmet, similar to the outline of the human head, which can not only support the model to avoid deformation, but also simulate the force state when the helmet is actually worn, making the deformation effect of the buffer layer closer to the real scene, and enhancing the authenticity of the science and education demonstration.
[0010] Furthermore, the upper end of the housing has an installation hole, the impact assembly includes a column, the column is installed in the installation hole, the bottom end of the column has a circular groove, the circular groove has an annular electromagnet installed inside, the bottom end of the annular electromagnet has an impact head, and the impact head and the annular electromagnet are magnetically connected.
[0011] The beneficial effects of adopting the above-mentioned further solution are that when the ring electromagnet is energized, it can firmly hold the impact head in place by magnetic force, and release it instantly after the power is cut off. This allows for precise control of the release timing and initial height of the impact head, ensuring that the force and speed of each impact are consistent, which facilitates comparison of the protective effects of different buffer layers. The ring electromagnet is magnetically connected to the impact head, allowing for quick replacement of impact heads of different weights and shapes, expanding the scenarios for teaching demonstrations such as impacts from sharp or blunt objects.
[0012] Furthermore, a round rod is installed at the center of the annular electromagnet, and a positioning groove is opened inside the round rod. A positioning post is slidably arranged inside the positioning groove, and the bottom end of the positioning post is fixedly connected to the upper end of the impact head.
[0013] Furthermore, the cross-section of the positioning post is cross-shaped, and the outer wall of the positioning post slides in conjunction with the inner wall of the positioning groove.
[0014] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the cross-shaped positioning post and the positioning groove, when different impact heads are disassembled and replaced, the positioning post of the impact head is inserted into the positioning groove to ensure that the column, the ring electromagnet, and the impact head are concentric.
[0015] Furthermore, the base has an internal cavity, and a pressure plate is slidably connected inside the cavity. The top surface of the pressure plate is fixedly connected to the bottom end of the support rod. A pressure gauge is embedded in one side of the outer wall of the base, and the detection end of the pressure gauge is in contact with the bottom end of the pressure plate.
[0016] The beneficial effect of adopting the above-mentioned further solution is that, by setting up a pressure gauge, when an impact occurs, the impact force is transmitted to the pressure plate through the helmet model, support base, and support rod. The pressure gauge can display the impact force value in real time, allowing learners to intuitively understand the impact resistance performance of the helmet model based on the impact force data.
[0017] Furthermore, both opposite sides of the box are hollow, and protective plates are rotatably connected to the interior of both opposite sides of the box. The protective plates are made of transparent acrylic material.
[0018] The beneficial effects of adopting the above-mentioned further solutions are that, by setting up a protective plate, the helmet model may produce fragments during the impact, and the protective plate can form a physical barrier to prevent the fragments from flying and injuring people, thus ensuring the safety of the teaching demonstration; by making the protective plate a transparent acrylic material, it does not affect the learner's observation of the helmet and the buffer layer during the impact, such as the dent of the buffer layer and the deformation of the helmet; the protective plate can be rotated and opened to facilitate the placement of the helmet model, and when closed, it forms a closed space to reduce external interference and avoid the influence of airflow on the falling path of the impact head.
[0019] Compared with existing technologies, the beneficial effects of this utility model are as follows: The safety helmet impact model structure for educational purposes uses a transparent polycarbonate helmet body, combined with a transparent protective plate, which allows for clear observation of the real-time deformation of the buffer layer during the impact. Furthermore, the transparent protective plate does not obstruct the learner's observation of the helmet body and buffer layer during the impact, such as the denting of the buffer layer and the deformation of the helmet body, thus improving the quality of educational content. When the annular electromagnet is energized, it can firmly hold the impact head in place through magnetic force. Upon de-energization, it releases instantly, allowing the impact head to fall rapidly under gravity and impact the safety helmet model. When the impact occurs, the impact force is transmitted through the safety helmet model, support base, and support rod to the pressure plate. The pressure gauge can display the impact force value in real time, enabling learners to intuitively understand the impact resistance performance of the safety helmet model based on the impact force data.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figures 1-5This utility model provides a technical solution: The upper end of the housing 11 has an internal mounting hole. The impact assembly 2 includes a column 21, which is installed in the mounting hole. A circular groove 22 is formed inside the bottom end of the column 21. A ring electromagnet 23 is installed inside the circular groove 22. An impact head 26 is provided at the bottom end of the ring electromagnet 23. The impact head 26 and the ring electromagnet 23 are magnetically connected. A circular rod 24 is installed at the center of the ring electromagnet 23. A positioning groove is formed inside the circular rod 24. A positioning post 25 is slidably arranged inside the positioning groove. The bottom end of the positioning post 25 is fixedly connected to the upper end of the impact head 26. The cross-section of the positioning post 25 is cross-shaped. The outer wall of the ring electromagnet 23 slides into the inner wall of the positioning groove. When the ring electromagnet 23 is energized, it can firmly hold the impact head 26 in place by magnetic force. When the power is cut off, it is released instantly, so that the impact head 26 falls rapidly under the action of gravity to impact the safety helmet model 3. Since the ring electromagnet 23 and the impact head 26 are magnetically connected, impact heads 26 of different weights and shapes can be quickly replaced, expanding the teaching demonstration scenarios such as impacts from sharp objects or blunt objects. Through the use of the cross-shaped positioning post 25 and the positioning groove, when different impact heads 26 are disassembled and replaced, the positioning post 25 of the impact head 26 is inserted into the positioning groove to ensure that the column 21, the ring electromagnet 23, and the impact head 26 are concentric.
[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figures 1-5This utility model provides a technical solution: A cavity is formed inside the base 13, and a pressure plate 17 is slidably connected inside the cavity. The top surface of the pressure plate 17 is fixedly connected to the bottom end of the support rod 15. A pressure gauge 18 is embedded in one side of the outer wall of the base 13, and the detection end of the pressure gauge 18 is in contact with the bottom end of the pressure plate 17. The opposite sides of the housing 11 are hollow, and protective plates 19 are rotatably connected inside the opposite sides of the housing 11. The protective plates 19 are made of transparent acrylic. By setting the pressure gauge 18, when an impact occurs, the impact force is transmitted to the pressure plate 17 through the safety helmet model 3, the support base 16, and the support rod 15. The pressure gauge 18 can display the impact in real time. The force values allow learners to intuitively understand the impact resistance performance of the helmet model 3 based on the impact force data. By setting up the protective plate 19, the helmet model 3 may produce fragments during the impact. The protective plate 19 can form a physical barrier to prevent the fragments from flying and injuring people, ensuring the safety of the teaching demonstration. By making the protective plate 19 a transparent acrylic material, it does not affect the learner's observation of the helmet body 31 and the buffer layer 32 during the impact, such as the dent of the buffer layer 32 and the deformation of the helmet body 31. The protective plate 19 can be rotated and opened to facilitate the placement of the helmet model. When closed, it forms a closed space to reduce external interference and avoid the influence of airflow on the falling path of the impact head 26.
[0032] Specifically, the working principle of this educational safety helmet impact model structure is as follows: During use, open the protective plate 19 on one side of the housing 11, place the safety helmet model 3 to be impacted on the support base 16, and then close the protective plate 19. This creates a closed space, reducing external interference and preventing airflow from affecting the falling path of the impact head 26. When the annular electromagnet 23 is energized, it firmly holds the impact head 26 in place using magnetic force. Upon de-energization, it releases instantly, allowing the impact head 26 to fall rapidly under gravity and impact the safety helmet model 3. The helmet body 31 is made of transparent polycarbonate, and together with the transparent protective plate 19, the real-time deformation of the buffer layer 32 during the impact can be clearly observed, facilitating learners' observation of the deformation of the helmet body 31 during the impact. The indentation of the buffer layer 32 can be observed to improve the quality of science education; when an impact occurs, the impact force is transmitted to the pressure plate 17 through the helmet model 3, the support base 16, and the support rod 15. The pressure gauge 18 can display the impact force value in real time, so that learners can intuitively understand the impact resistance performance of the helmet model 3 based on the impact force data; since the annular electromagnet 23 is magnetically connected to the impact head 26, impact heads 26 of different weights and shapes can be quickly replaced, expanding the teaching demonstration scenarios such as impacts from sharp objects or blunt objects; through the combined use of the cross-shaped positioning post 25 and the positioning groove, when different impact heads 26 are disassembled and replaced, the positioning post 25 of the impact head 26 is inserted into the positioning groove to ensure that the column 21, the annular electromagnet 23, and the impact head 26 are concentric.
