Abstract
Description
Technical fields:
[0001] This utility model relates to the field of helmet technology, and in particular to a helmet with an adjustable cushioning liner shape. Background technology:
[0002] Commercially available safety helmet liners are typically made of non-flowing materials such as elastic sponge or foamed plastic. However, head shapes vary from person to person, and common helmets cannot fit everyone. Because the internal cushioning layer of standard-sized helmets is generally manufactured in a uniform shape, it doesn't provide a suitable fit for different users' heads. This results in helmets that are too large, causing the cushioning layer to be too loose and unstable, creating safety hazards, or helmets that are too small, causing pressure on the user's head and resulting in insufficient comfort. Therefore, there is an urgent need for a safety helmet with an adjustable liner to fit different head shapes while increasing both safety and comfort. Utility model content:
[0003] The technical problem to be solved by this utility model is to provide a helmet with an adjustable cushioning liner shape. This helmet allows for convenient adjustment of the cushioning liner size, is suitable for different head shapes, can stably fix the user's head, and increases comfort while preventing the safety helmet cushioning liner from having excessive or insufficient pressure overall or locally.
[0004] The technical solution adopted by this utility model is: a helmet with an adjustable inner liner shape, including a helmet body and a foam cushioning layer disposed inside the helmet body; characterized in that: it also includes an inflation mechanism, an air storage system, and an inflatable cushioning layer;
[0005] The inflation mechanism is located on the outside of the helmet body, and the inflation mechanism includes an air pump and an inflation control module;
[0006] The gas storage system is set in the installation groove reserved on the foam buffer layer. The gas storage system includes multiple elastic gas storage bags and a main vent pipe connected to each elastic gas storage bag. The air inlet end of the main vent pipe is connected to a one-way valve I and an air pump. The air outlet end of the main vent pipe is connected to an air valve. A gas pressure sensor of the gas storage system is set on the gas storage system.
[0007] The inflatable buffer layer is located inside the foam buffer layer. The inflatable buffer layer includes a static elastic buffer air chamber located at the top of the head and dynamic elastic buffer air chambers located on both sides of the face. The air inlet of the dynamic elastic buffer air chamber is connected to a one-way valve II and is connected to the air outlet of the main air pipe. An exhaust valve and an inflatable buffer layer air pressure sensor are installed on the dynamic elastic buffer air chamber.
[0008] The inflation control module collects the pressure information from the air pressure sensor of the air storage system and the air pressure sensor of the inflation buffer layer. The inflation control module can control whether the inflation pump inflates the air storage system and whether the air valve is closed.
[0009] Furthermore, the inflation mechanism is mounted on the back of the helmet body via an inflation mechanism base. The inflation mechanism base is provided with an air outlet connected to the air inlet of the main vent pipe. This air outlet is connected to the air outlet of the inflation pump via a vent pipe.
[0010] Furthermore, the inflation mechanism includes a battery, a main power switch, and an air valve control switch. The battery supplies power to the inflation pump and the inflation control module. The main power switch controls the connection and disconnection between the battery and the inflation pump and the inflation control module, respectively. The air valve control switch can control the opening of the air valve.
[0011] Furthermore, the inflation control module includes an alarm module. When the inflation time of the air pump exceeds the set alarm time, the alarm module controls the air pump to stop inflation and issues an audible alarm via a buzzer or an indicator light.
[0012] Furthermore, the elastic air reservoir, static elastic buffer chamber, and dynamic elastic buffer chamber are all made of elastic rubber.
[0013] Furthermore, the static elastic buffer chamber is provided with an air inlet.
[0014] Furthermore, the dynamic elastic buffer air chamber comprises an upper dynamic elastic buffer air chamber and a lower dynamic elastic buffer air chamber. The upper dynamic elastic buffer air chamber is arranged around the back of the human head and the cheekbones on both sides, while the lower dynamic elastic buffer air chamber is arranged around the lower part of the back of the human head and the cheeks on both sides. The upper and lower dynamic elastic buffer air chambers are connected by a ventilation tube.
[0015] Furthermore, an emergency exhaust valve is provided on the dynamic elastic buffer chamber.
[0016] Furthermore, a manual inflation valve is provided on the dynamic elastic buffer chamber.
[0017] Furthermore, when the internal air pressure of the air storage system is lower than the set air pressure I, the inflation control module can control the inflation pump to inflate the air storage system. When the internal air pressure of the air storage system is higher than the set air pressure II, the inflation control module can control the inflation pump to stop inflating the air storage system. When the internal air pressure of the dynamic elastic buffer chamber reaches the set air pressure III, the inflation control module can control the air valve to close.
[0018] The beneficial effects of this utility model are: This utility model realizes convenient adjustment of the size of the cushioning liner, which is suitable for different user head shapes, can stably fix the user's head, and at the same time increase comfort, prevent the problem of excessive or insufficient pressure on the overall or local cushioning liner of the safety helmet. In addition, the size of the opening at the bottom of the helmet can be changed, which makes it convenient to put on and take off the helmet quickly, avoiding the traditional wearing process of squeezing the head.

[0026] like Figure 1 As shown, a helmet with an adjustable inner liner shape includes a helmet body 1, a foam cushioning layer 2 disposed inside the helmet body 1, and also includes an inflation mechanism 3, an air storage system, and an inflatable cushioning layer.
[0027] like Figure 2 , Figure 3 As shown, the inflation mechanism 3 is located on the outside of the helmet body 1. The inflation mechanism 3 includes an air pump 9 and an inflation control module 10. The inflation mechanism 3 includes a battery 11, a main power switch 7, and an air valve control switch 8. The battery 11 supplies power to the air pump 9 and the inflation control module 10. The main power switch 7 controls the connection and disconnection between the battery 11 and the air pump 9 and the inflation control module 10, respectively. The air valve control switch 8 can control the opening of the air valve 17.
[0028] like Figure 4 , Figure 5As shown, the gas storage system is installed in the pre-reserved installation groove on the foam buffer layer 2. The gas storage system includes multiple elastic gas storage bags 13 and a main vent pipe 14 connected to each elastic gas storage bag 13. The air inlet end of the main vent pipe 14 is connected to a one-way valve I 15 and is connected to an air pump 9. The air outlet end of the main vent pipe 14 is connected to an air valve 17. A gas storage system pressure sensor 16 is installed on the gas storage system.
[0029] like Figure 6 As shown, the inflatable buffer layer is disposed inside the foam buffer layer 2. The inflatable buffer layer includes a static elastic buffer air chamber 4 disposed at the top of the head and dynamic elastic buffer air chambers 5 disposed on both sides of the face. The air inlet of the dynamic elastic buffer air chamber 5 is connected to a one-way valve II 22 and is connected to the air outlet of the main air pipe 14. An exhaust valve 19 and an inflatable buffer layer air pressure sensor 21 are disposed on the dynamic elastic buffer air chamber 5.
[0030] The inflation control module 10 collects the pressure information of the gas storage system pressure sensor 16 and the inflation buffer layer pressure sensor 21. The inflation control module 10 can control whether the inflation pump 9 inflates the gas storage system and whether the air valve 17 is closed.
[0031] The inflation mechanism 3 is installed behind the helmet body 1 via the inflation mechanism base 6. The inflation mechanism base 6 is provided with an air outlet 12 connected to the air inlet end of the main air pipe 14. The air outlet 12 is connected to the air outlet end of the air pump 9 via an air pipe.
[0032] The inflation mechanism 3 includes a battery 11, a main power switch 7, and an air valve control switch 8. The battery 7 supplies power to the inflation pump 9 and the inflation control module 10. The main power switch 7 controls the connection and disconnection between the battery 7 and the inflation pump 9 and the inflation control module 10, respectively. The air valve control switch 8 can control the opening of the air valve 17.
[0033] The inflation control module 10 includes an alarm module. When the inflation time of the air pump 9 exceeds the set alarm time, the alarm module controls the air pump 9 to stop inflation and issues an alarm by sounding a buzzer or by lighting an indicator light.
[0034] The elastic air reservoir 13, the static elastic buffer air chamber 4, and the dynamic elastic buffer air chamber 5 are all made of elastic rubber.
[0035] The static elastic buffer chamber 4 is provided with an air inlet 20.
[0036] The dynamic elastic cushioning chamber 5 comprises an upper dynamic elastic cushioning chamber and a lower dynamic elastic cushioning chamber. The upper dynamic elastic cushioning chamber is arranged around the back of the head and the cheekbones on both sides, while the lower dynamic elastic cushioning chamber is arranged around the lower part of the back of the head and the cheeks on both sides. The upper and lower dynamic elastic cushioning chambers are connected by a ventilation tube. The arrangement of the inflatable cushioning layer is scientific and reasonable. By inflating the cheeks, forehead, top of the head, back of the head, and the head cushioning chamber, the inflatable cushioning layer of the helmet can be firmly attached to the user's face, with even pressure distribution and increased comfort.
[0037] An emergency exhaust valve 23 is provided on the dynamic elastic buffer air chamber 5.
[0038] The dynamic elastic buffer air chamber 5 is equipped with a manual inflation valve 18.
[0039] When the internal air pressure of the air storage system is lower than the set air pressure I, the inflation control module 10 can control the inflation pump 9 to inflate the air storage system. When the internal air pressure of the air storage system is higher than the set air pressure II, the inflation control module 10 can control the inflation pump 9 to stop inflating the air storage system. When the internal air pressure of the dynamic elastic buffer air chamber 5 reaches the set air pressure III, the inflation control module 10 can control the closing of the air valve 17.
[0040] In use, pressing the main power switch 7 activates the inflation control module 10, which collects data from the gas pressure sensor 16 of the gas storage system. When the internal gas pressure of the gas storage system is lower than the set pressure I, the inflation control module 10 controls the inflation pump 9 to inflate the gas storage system. When the internal gas pressure of the gas storage system is higher than the set pressure II, the inflation control module 10 controls the inflation pump 9 to stop inflating the gas storage system. Inflation stops and a warning is issued if the inflation time exceeds the set warning time.
[0041] After the air storage system is fully inflated, put on the helmet and press the air valve control switch 8. The air valve 17 will open, and the air storage system will inflate the dynamic elastic buffer chamber 5 of the inflatable buffer layer. When the internal air pressure of the dynamic elastic buffer chamber 5 reaches the set air pressure III, the inflation control module 10 will control the air valve 17 to close. During the inflation process of the air storage system into the inflatable buffer layer, if the internal air pressure of the air storage system is lower than the set air pressure I, the inflation control module 10 will control the air pump 9 to inflate the air storage system again.
[0042] When the helmet needs to be removed, open the exhaust valve 19 to allow the gas in the dynamic elastic buffer chamber 5 to flow out, reducing the air pressure and allowing the user to easily remove the helmet. In case of emergency removal of the helmet, pull down the emergency exhaust valve 23 to quickly expel air from the dynamic elastic buffer chamber 5, thus facilitating the removal of the helmet.
[0043] When the inflation mechanism 3 and the air storage system fail to work for various reasons, the manual air pump 18 can be used to replenish the dynamic elastic buffer air chamber 5.
[0044] It is understood that the above specific description of this utility model is only used to illustrate this utility model and is not limited to the technical solutions described in the embodiments of this utility model. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
