Description

Technical Field

[0001] The utility model relates to the technical field of protective equipment, in particular to a helmet. Background Art

[0002] With the development of social economy and the improvement of family consumption capacity, bicycles, electric vehicles, motorcycles and other means of transportation have become more and more popular among people, and helmets have gradually become a hot topic in the market. Helmets are protective equipment for the head, which can prevent specific head injury risks, especially moderate to severe head injuries. Helmets play an important role in the prevention and control of head injuries.

[0003] Currently, the helmets on the market are mainly divided into two types: driver or passenger helmets and sports helmets. Among them, sports helmets are head protection devices that reduce accidental injuries to the wearer's head by blocking impact objects, dispersing impact energy, absorbing impact energy, etc. during exercise. They are suitable for wearing and using when participating in sports such as cycling, roller skating, and skateboarding. Sports helmets are generally composed of a shell, a buffer layer, a comfortable liner, a wearing device, etc. The shell refers to the outer shell of the helmet, which plays an important role in safety; the main function of the buffer layer is to absorb external impact force, and generally uses foam materials such as expanded polystyrene (EPS) and expanded polypropylene (EPP); the main function of the comfort liner is to enhance the comfort when wearing, and it is generally made of soft velvet, and its function is to firmly fix the helmet to the head.

[0004] Existing sports helmets usually adopt the above-mentioned shell-buffer layer-pad structure. The shell is used to resist external impact and prevent the buffer layer from direct contact with external forces. The buffer layer absorbs a large amount of energy by utilizing the compression of its internal gas and the deformation of the foam. The pad is in contact with the human body to ensure comfort. However, such a helmet structure has the disadvantage of insufficient structural strength: the shell and buffer layer are the main protective elements in existing helmets, and the deformation of the buffer layer is generally divided into three stages. The first stage is the compression deformation stage of squeezing out the pore gas, the second stage is a longer deformation stage under stable stress, and the third stage is the densification deformation stage in which the stress rises sharply after being compacted. In the first stage, the buffer layer will produce a small compression deformation, at this time the buffer layer absorbs less impact energy, resulting in poor buffering effect of the buffer layer; in the second stage, after plastic yielding, the buffer layer produces a longer deformation under stable stress to resist the external impact force, the buffering effect is better, and most of the energy absorption occurs in this stage; in the third stage, after the buffer layer is compacted, the hole has almost completely collapsed, the relative hole walls begin to contact, and the stress rises sharply. At this time, the buffering effect is lost and the user's head cannot be effectively protected. Therefore, the existing helmets have inconsistent buffering protection effects at different stages when subjected to external impact forces, especially in the early and late stages of the impact, the pressure on the helmet is too large, which can easily cause the user's head to be injured. Moreover, the buffer layer absorbs most of the impact energy during the deformation process of compressed gas, and a small part of the impact energy is directly transmitted to the head, resulting in excessive pressure on the user's head, which is easy to be injured. Since the shell thickness has little effect on the protective effect, the protective effect can only be enhanced by increasing the thickness of the buffer layer, and blindly increasing the thickness of the buffer layer will make the helmet heavier, causing the helmet to become a greater burden on the user's head. On the contrary, if the thickness of the buffer layer is insufficient, the protective performance of the helmet is insufficient. Utility Model Content

[0005] The main purpose of the utility model is to provide a helmet, aiming to solve the technical problem that the existing helmets have insufficient protective performance.

[0006] To achieve the above object, the utility model provides a helmet, comprising:

When the thickness of the helmet is low, the support component can also effectively prevent the damage of the helmet, thereby achieving safe protection under the condition of reducing the thickness. In addition, when the support component is impacted, the force will be transmitted to the base layer directly connected to the support component, so that the force-bearing area is further increased, effectively reducing the local pressure. The support component, base layer and buffer layer of the utility model are combined with each other to make up for each other's shortcomings and effectively reduce the probability of the user's head being injured by external force.

[0047] The helmet 100 provided in this embodiment is mainly used to protect the head and prevent the head from being injured by external force impact. The helmet 100 provided in this embodiment can be a helmet for motorcycle or electric vehicle drivers or passengers, a safety helmet worn by construction workers, or a sports helmet, such as a helmet worn by athletes of bicycles, skateboards, roller skates, ice and snow sports, etc. Of course, this is only exemplary, including but not limited to this.

[0048] Please refer to Figures 1 to 5 The helmet 100 provided in the first embodiment of the utility model includes:

[0049] Shell 10. In this embodiment, the shell 10 can be made of PC material, ABS material, carbon fiber material, glass fiber material, ABS / PC mixed material and other materials with high elastic modulus that are tough, heat-resistant and cold-resistant. These materials have a high elastic modulus, generally above 500Mpa, and a Poisson's ratio between 0 and 0.4. The shell 10 made of these materials is used as a direct impact layer, and can rely on its high elastic model to resist deformation, ensure that the helmet 100 will not be broken, and avoid the buffer layer directly contacting the impact object and causing damage.

[0050] The base layer 20 is connected to the shell 10 and forms a buffer space. In this embodiment, the base layer 20 can also be made of PC material, ABS material, carbon fiber material, glass fiber material, ABS / PC mixed material and other materials with high elastic modulus, which are tough, heat-resistant and cold-resistant, to ensure that the helmet 100 will not be damaged or broken under impact.

[0051] The force-supporting buffer component 40 includes a plurality of supporting components 41 distributed in the buffer space, one end of the supporting component 41 is at least partially exposed outside the outer shell 10, and the other end of the supporting component 41 is connected to the base layer 20. The base layer 20 supports the force-supporting buffer component 40 and the buffer layer, thereby further enhancing the protective effect of the helmet 100.

[0052] In this embodiment, the supporting component 41 can also be made of PC material, ABS material, carbon fiber material, glass fiber material, ABS / PC mixed material and other materials with high elastic modulus that are tough, heat-resistant and cold-resistant to ensure that the helmet 100 will not be damaged or broken under impact.

[0053] In this embodiment, one end of the support component 41 is at least partially exposed outside the shell 10, which may include a situation where the support component 41 is flush with the surface of the shell 10, or a situation where the support component 41 is recessed at a certain distance from the surface of the shell 10, or a situation where the support component 41 is slightly protruding outside the shell 10. The purpose is to ensure that when the helmet 100 is subjected to external impact, the support component 41 can absorb the impact force.

[0054] The buffer layer (not shown) is disposed in the buffer space and covers the periphery of the force-bearing support buffer component 40 .

[0055] In this embodiment, the main function of the buffer layer is to absorb external impact force, and generally a foam material is used, such as expanded polystyrene (EPS), expanded polypropylene (EPP), etc. If the helmet 100 does not have a buffer layer, when it encounters an external force impact, the external force will directly act on the head through the hard shell 10, which will cause damage to the head. Therefore, the helmet 100 of the utility model is provided with a buffer layer, and the buffer layer is deformed when it receives the impact force transmitted by the shell 10, so as to absorb part of the external impact force, thereby playing a role in protecting the head.

[0056] Among them, each supporting component 41 includes a main body 412, the main body 412 has a first surface 413 formed on the base layer 20 and a second surface 414 away from the first surface 413, the main body 412 extends between the first surface 413 and the second surface 414, and the axis of each main body 412 intersects with the normal line of the surface of the base layer 20 where the main body 412 is located, that is, the main body 412 of the utility model is inclined relative to the surface of the base layer 20. When the helmet 100 is subjected to external impact, the main body 412 is subjected to impact forces from various directions, resulting in distortion and deformation in different directions to absorb most of the external impact force.

[0057] The buffer layer in this embodiment is wrapped around the periphery of the force-supporting buffer component 40, which can well compensate for the defects of the buffer layer material: when the helmet 100 is subjected to an external impact, the outer shell 10 transfers the impact force to the buffer layer. At this time, the buffer layer is in the first stage, and the buffer layer absorbs a small part of the external impact force. At the same time, the main body 412 of the support component 41 is subjected to impact forces from all directions, resulting in distortion and deformation in different directions to absorb most of the external impact force, which plays a good buffering and protective role in the early stage of the external impact of the helmet 100, prolonging the buffering and protection time of the helmet 100 during the external impact, thereby reducing the probability of the user's head being injured by the impact of external force; when the support component 41 is twisted and deformed, part of the impact force will be transferred to the buffer layer and the base layer 20. At this time, the buffer layer is in the second stage, which can produce a longer deformation under stable stress and has a strong impact energy absorption effect to resist the external impact force, thereby absorbing the remaining external impact force with the base layer 20, reducing the deformation degree of the buffer layer, and avoiding the deformation of the buffer layer reaching the limit (third stage) and losing the buffering and protective effect.

[0058] In this embodiment, the force-supported buffer component 40 is always in a state of being wrapped by the buffer layer. In addition to the force-supported buffer component 40 absorbing energy through deformation in different directions, the buffer layer wrapped around the outer periphery of the force-supported buffer component 40 and the base layer 20 supported at the bottom of the force-supported buffer component 40 also play a buffering and protective role. When the helmet 100 is impacted by an external force, after the support component 41 is impacted, the force will be transmitted to the base layer 20 directly connected to the support component 41, so that the force-bearing area is further increased, thereby jointly dispersing and absorbing the external impact force generated, effectively reducing the local pressure, and making the external pressure smoothly transition under the buffering effect of the support component 41, the buffer layer and the base layer 20, thereby improving the anti-collision ability of the helmet 100, thereby effectively reducing the probability of the user's head being injured by the impact of external force.

[0059] Compared with the traditional helmet structure, the buffer layer, the force-supporting buffer component 40 and the base layer 20 of the utility model form a soft-hard combination buffer structure. When initially impacted, the buffer layer is in the first stage, with low energy absorption efficiency, while at this time the base layer 20 and the support component 41 have a high elastic modulus, can absorb energy, and are not easily deformed; after the base layer 20 and the support component 41 yield, they undergo a large deformation, at which time the buffer layer enters the second stage, with high energy absorption efficiency and better buffering effect, thereby compensating for each other's shortcomings, deforming and absorbing impact energy in their respective advantage ranges, so as to complement each other and jointly provide complete safety protection. When the thickness of the helmet 100 is relatively low, the support component 41 can also effectively prevent the damage of the helmet 100, and achieve safe protection under the condition of reducing the thickness of the helmet 100.

[0060] In some embodiments, the helmet 100 further includes a liner (not shown), which is connected to the bottom of the base layer 20 and is used to contact the wearer. The liner is made of a soft material (such as silica gel, etc.), which can improve the comfort of the wearer wearing the helmet 100.

[0061] In this embodiment, the base layer 20 is hemispherical, matching the shape of the head, and can increase the force-bearing area to disperse the external impact force.

[0062] Please refer to Figure 6 A plurality of support components 41 are arranged in a ring-shaped interval pattern, each circle of support components constitutes a support component group 42, and there are at least two support component groups 42. The support components 41 in adjacent support component groups 42 face the same direction or different directions.

[0063] In this embodiment, the orientations of the support components 41 in adjacent support component groups 42 are set to be different, and at least two groups of support component groups 42 are distributed in various directions of the helmet 100. By setting the support components 41 in different orientations, it is ensured that the support components 41 can play an effective deformation role when the helmet 100 is hit in different directions.

[0064] Of course, in other embodiments, the orientations of the support components 41 in adjacent support component groups 42 may also be set to be the same, which is not limited in the embodiment of the present application.

[0065] In this embodiment, the distribution of the support components 41 can be evenly spaced, or can be arranged in key areas according to the impact force points. Figure 4 As shown, the number of support component groups 42 distributed on the helmet 100 can be specifically set according to the different protection ranges and protection areas, and the number of support components 41 in the support component group 42 and the distribution pattern of the orientation can also be optimized and adjusted as a whole. For example, the tilt direction of the support component 41 is toward another support component 41 close to it, and the support components 41 of each group are arranged in a clockwise or counterclockwise direction. The support components 41 of two support component groups 42 have different orientations. In this way, the support component group 42 can withstand impact forces from multiple directions, thereby generating more deformation and absorbing energy, so that the helmet 100 has no weak points and enhances the protective performance of the helmet 100. Of course, the number of support component groups 42 and the orientation of the support components 41 can also be set to other, which is only exemplary, including but not limited to this.

[0066] In some embodiments, three adjacent support components 41 in an adjacent support component group 42 are distributed in a triangle, which can be an equilateral triangle or an isosceles triangle. The purpose of such a distribution arrangement is to allow the support components 41 to contact the impact force from different directions when an impact occurs, so that each position of the helmet 100 can play a buffering and protective role, and the multiple support components 41 arranged in a triangle are stably stressed and are not prone to displacement or shaking.

[0067] Of course, the plurality of support components 41 in the adjacent support component groups 42 may also be arranged in other shapes, such as a rectangle, etc., but is not limited thereto.

[0068] After the helmet is designed, its collision absorption performance needs to be tested. Therefore, according to the existing test method (GB24429-2009 Safety requirements and test methods for sports helmets for bicycles, skateboards, and roller skating sports helmets), the utility model tests the collision energy absorption performance of the existing helmet and the helmet 100 of the embodiment of the present application, respectively. Acceleration sensors are installed in the existing helmet and the helmet 100 of the embodiment of the present application, respectively, to obtain the acceleration magnitude generated by the existing helmet and the helmet 100 of the embodiment of the present application after hitting the same test anvil at the same height, so as to detect the collision energy absorption performance of the helmet. In this embodiment, multiple groups of experimental controls can be carried out to improve the accuracy of the experiment.

[0069] Please refer to Figure 7 , Figure 7 The curve diagram of the acceleration variation with time in the collision energy absorption performance test of the existing helmet is shown in the curve diagram. It can be seen from the curve diagram that the existing helmet is subjected to the maximum impact force at 0.0032S, and the peak acceleration generated by the existing helmet after impacting the test anvil is 7.04*10 3 m / s 2 This indicates that the existing helmets can absorb less impact energy after a collision, resulting in a weaker impact resistance of the existing helmets, thereby increasing the probability of the user's head being injured.

[0070] Please refer to Figure 8 and Fig. 9 , Figure 8 Schematic diagram of a head-on impact test of the helmet 100 of the present invention. Fig. 9 1 is a curve diagram showing the acceleration of the helmet 100 of the present invention when it is directly impacted with the test anvil. It can be seen from the curve diagram that the impact force on the helmet 100 of the present invention is the largest at 0.00288S, and the peak acceleration generated by the helmet 100 after impacting the test anvil is 3.24*10 3 m / s 2This shows that the helmet 100 of the embodiment of the present application can absorb more impact energy after the impact, and the helmet 100 has a strong impact resistance, thereby reducing the probability of the user's head being injured. Compared with the traditional helmet, the protective performance of the helmet 100 of the utility model is improved by about 20%-40%.

[0071] In addition, please refer to Figures 10 to 13 , respectively, are test schematic diagrams of the side impact and forehead impact of the helmet 100 of the utility model, and a curve schematic diagram of the acceleration changing with time. The peak acceleration generated by the helmet 100 after impacting the test anvil is less than 3.24*10 3 m / s 2 This shows that the helmet 100 of the embodiment of the present application can absorb more impact energy regardless of the top impact, side impact or forehead impact. The helmet 100 has a strong impact resistance and comprehensive protection. The external pressure is smoothly transitioned under the buffering effect of the support component 41, the buffer layer and the base layer 20, so that the entire helmet 100 always maintains sufficient strength during external impact, thereby reducing the probability of the user's head being injured by external force.

[0072] It should be noted that when the existing helmet or the helmet 100 of the present invention is tested for head-on impact, side impact or forehead impact, except for the different settings of the helmet impact surface, other test conditions need to be set to the same (such as drop height, roughness of the test anvil, etc.) to make the measured data comparable.

[0073] The structure of existing helmets is relatively closed. The head is the most important part of the human body. When exercising or in a hot environment, the head dissipates heat by secreting sweat to prevent the head from overheating. When wearing a helmet, the relatively closed structure of the helmet leads to insufficient ventilation, and sweat is difficult to evaporate and dissipate, which makes people feel uncomfortable and may even cause symptoms of heat stroke in severe cases. One of the reasons why many people are reluctant to wear helmets when exercising or in a hot environment is the discomfort caused by the difficulty in dissipating heat when wearing a helmet.

[0074] In order to solve the above problems, the shell 10 of the utility model is provided with a first vent 11 penetrating the inner and outer walls thereof, and the base layer 20 is provided with a second vent 21 penetrating the inner and outer walls thereof; each body is provided with a vent channel 411 penetrating from the first surface 413 to the second surface 414, one end of the vent channel 411 is opened to communicate with the first vent 11, and the other end of the vent channel 411 is opened to communicate with the second vent 21, and the gas can enter the vent channel 411 through the second vent 21 and be discharged through the first vent 11, thereby ensuring the air circulation inside the helmet 100. In this way, the heat generated when the user wears the helmet 100 can flow through the vent channel 411 and be discharged from the first vent 11, thereby increasing the ventilation area, thereby dissipating heat in time, and improving the wearing comfort of the wearer, which is particularly suitable for athletes.

[0075] Compared with the traditional helmet structure, the thickness of the helmet 100 of the present invention is reduced by about 30%-50%, and the ventilation volume is increased by about 40%-50%.

[0076] Please continue to refer to Figure 4 and Figure 5 In some embodiments, the angle α formed between the axis of each body 412 and the surface of the base layer 20 where the body 412 is located is greater than 10° and less than 90°, that is, the support component 41 is inclined relative to the base layer 20. 1 For example, when the helmet 100 is hit, the support component 41 is hit by impact forces from different directions, including a direct impact force F from the outside. 1 , and F 1 The impact force F that reaches the inclined surface of the support component 41 after passing through the housing 10 and the buffer layer 2 Due to the integrity of the buffer layer, the impact force F 1 The buffer layer begins to diffuse and squeeze the support component 41 wrapped therein, causing the buffer layer to be compressed and deformed, and the support component 41 to be deformed and squeezed, thereby absorbing F 1 and F 2 of impact energy.

[0077] In this embodiment, there is an angle α between the support component 41 and the base layer 20, so that the support component 41 can withstand impact forces from multiple directions, thereby generating more deformation and absorbing energy, and finally reaching the impact force F of the base layer 20 3 The force will also be further diffused through the base layer 20 , so that each structure of the helmet 100 becomes a force-bearing object, which greatly increases the force-bearing area and improves the protective performance of the helmet 100 .

[0078] In some embodiments, the height of each body 412 is 3 mm-50 mm.

[0079] In some embodiments, the diameter of each body 412 is 2 mm-50 mm.

[0080] Please continue to refer to Figure 4 Each main body 412 and the base layer 20 are an integrally formed structure. Each main body 412 is a hollow columnar structure. The air permeable channel 411 is formed inside the columnar structure. The integrally formed structure can increase the impact resistance of the support component 41 and the base layer 20, and further reduce the probability of head injury to the user.

[0081] In some embodiments, the body 412 is at least partially protruded toward the outside of the body 412, and when the helmet 100 is subjected to an external impact, the body 412 can be flexed and deformed to absorb and disperse the impact energy. In this embodiment, the middle part of the body 412 is slightly protruded toward the outside, so that when the body 412 is subjected to an external force, the stress borne by the middle part of the body 412 is greater, while the stress borne by the edge part is smaller, which can better disperse the load and have a higher load-bearing capacity. The load-bearing capacity of the body 412 of the utility model increases with the increase of its radius of curvature, and can be specifically set according to actual conditions, without being limited thereto.

[0082] In some embodiments, the aperture of the air channel 411 gradually increases from the second surface 414 to the first surface 413, that is, the air channel 411 tends to be smaller at the top and larger at the bottom, so that the body 412 can be deformed when impacted from multiple directions to disperse the external impact force.

[0083] In some embodiments, the longitudinal cross section of the support component 41 is a trapezoid. Since the longitudinal cross section of the support component 41 of the present invention is a trapezoid, the support component 41 will not be separated from the first vent hole 11. Of course, in other embodiments, the longitudinal cross section of the support component 41 may also be other shapes, such as a rectangle, etc., including but not limited to this.

[0084] In some embodiments, the aperture of the first vent hole 11 is larger than the diameter of the support component 41, and a first buffer 50 is filled between the inner wall of the first vent hole 11 and the outer wall of the support component 41. In this embodiment, the first buffer 50 can be made of foam and is located between the housing 10 and the support component 41 to achieve soft contact and prevent the housing 10 and the support component 41 from being damaged by collision.

[0085] In some embodiments, please refer to Fig.14 The base layer 20 is provided with at least one through hole 22, at least one through hole 22 is provided between two adjacent support members 41, and at least one through hole 22 is filled with a second buffer 23. In this embodiment, the second buffer 23 can be made of foam, and the foam is directly filled in the through hole 22.

[0086] In this embodiment, the through holes 22 are distributed between different support components 41, and the apertures of the multiple through holes 22 can be the same or different, which can be set according to actual conditions. The base layer 20 of the utility model is distributed with multiple through holes 22, which is used to reduce the weight of the entire helmet 100 and reduce the burden on the wearer. In addition, there is a sufficient distance between the through holes 22 and the periphery of the support component 41 to ensure that the base layer 20 plays a supporting and buffering role, while reducing the pressure received.

[0087] In some embodiments, the outer shell 10 is sealed with foam edges, which can further reduce the weight of the entire helmet 100 and reduce the burden on the wearer.

[0088] In summary, when the helmet 100 of the utility model is subjected to external impact, the shell 10 transmits the impact force to the buffer layer. At this time, the buffer layer is in the first stage, and the buffer layer absorbs part of the external impact force. At the same time, the support component 41 is subjected to impact forces from all directions, resulting in distortion and deformation in different directions to absorb part of the external impact force, which plays a good buffering and protective role in the early stage of the external impact; when the buffer layer is in the second stage, the support component 41, the buffer layer, and the base layer 20 work together to disperse and absorb the generated external impact force, and the external pressure is smoothly transitioned under the buffering effect of the support component 41, the buffer layer and the base layer 20, extending the buffering and protection time of the entire helmet 100 during the external impact. In addition, the base layer 20 can support the buffer layer and the support component 41. When the helmet 100 is impacted by external force, the support component 41 will transmit the force to the base layer 20 directly connected to the support component 41 after being impacted, so that the force area is further increased, the local pressure is reduced, and the probability of the user's head being injured by the impact of external force is effectively reduced.

[0089] The above embodiments of the utility model are merely examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the utility model are still within the scope of protection of the utility model.
