Technical Field
[0001] The utility model belongs to the technical field of bulletproof helmets, in particular to a bulletproof helmet with a breathable structure component. Background Art
[0002] Bulletproof helmets mainly solve two aspects of protection problems: on the one hand, providing ballistic protection, and on the other hand, providing impact protection; the helmet body is the main part of ballistic protection, which can prevent fragments and projectiles from penetrating and provide effective protection for the human head; the cushion provides buffering for the helmet to ensure that the helmet meets the impact absorption performance requirements.
[0003] In the prior art, there is a non-metallic bulletproof helmet body made of high-performance fibers. Due to bulletproof requirements, it is impossible to improve the breathability of the helmet by opening holes in the helmet like a cycling helmet. Therefore, the breathability of this non-metallic bulletproof helmet is also poor.
[0004] Currently, in order to meet the requirements of impact energy absorption and comfort, the cushion of bulletproof helmets usually adopts a laminated structure of one or more materials such as EVA, EPS, EPP, plastic buffer structures, sponges, and memory foams. The materials themselves have poor breathability, and in the cushion design, the focus is on improving impact protection performance and comfort in contact with the head, increasing the thickness of the cushion and the contact area with the head, resulting in poor heat dissipation efficiency of the head when wearing the helmet, greatly affecting the thermal comfort of the user wearing the helmet, thus reducing combat effectiveness and even threatening the life and health of personnel. Content of the Utility Model
[0005] The purpose of the utility model is to provide a bulletproof helmet with a breathable structure component to solve the problem of sultry discomfort when wearing a bulletproof helmet for a long time in the prior art. By improving the cushion, the helmet body fixing system, and the structure of the back cushion, without reducing the requirements of bulletproof and buffering, the breathability of the helmet is greatly improved. The cushion buffer layer adopts a double-foot arch structure, and the comfort layer adopts a breathable hole design, reducing the contact area between the cushion and the head. The webbing of the back cushion is fixed in a 45° cross, and a "W"-shaped spacer is added on the side close to the head to isolate the head circumference adjustment knob and the webbing, improving breathability.
[0006] To achieve the above purpose, the utility model provides the following technical solutions:
[0007] A bulletproof helmet with a breathable structure component, comprising: a helmet body, a cushion, and a helmet body fixing system;
[0008] The helmet body: is laminated by high-performance fiber non-woven fabric;
[0009] As an example, a coating is sprayed on the outer surface of the helmet body.
[0010] As an example, a rubber strip is pasted at the lower edge of the helmet body.
[0011] The liner includes: multiple groups of liner units; each group of liner units is a binary laminated structure of a buffer layer and a comfort layer;
[0012] As an example, the liner is used for: functions of impact resistance and breathability improvement.
[0013] As an example, the binary laminated structure means that: the buffer layer is located on one side of the helmet body for impact resistance; the comfort layer is located on one side of the head for comfort improvement, and the buffer layer and the comfort layer are movably connected by a magic tape.
[0014] As an example, the projected shape of each group of liner units is oval, ensuring that after the liner units are arranged inside the helmet body, a narrow ventilation channel can be formed between each group of liner units, which helps to increase the wind speed of the passing air flow by the venturi effect.
[0015] As an example, the buffer layer: has a double-foot arch bridge structure; fits the shape of the helmet with a certain curvature, and a "U"-shaped ventilation groove is provided on the side close to the head in the middle of the buffer layer, and buffer pads are provided below the two feet of the double-foot arch bridge structure.
[0016] As an example, the comfort layer includes: multiple groups of comfort units; each group of comfort units adopts a structure of wrapping a flexible material block with flannelette and breathable mesh fabric.
[0017] As an example, the comfort units are in groups of two and are correspondingly pasted on the buffer pads.
[0018] As an example, the shape of the comfort unit is the same as that of the buffer pad, and the planar dimension of the comfort unit is slightly larger than that of the buffer pad.
[0019] As an example, the arrangement of the liner units inside the helmet body is: one in the front, two on the top, one in the back, and one on each of the left and right in an aligned arrangement.
[0020] As an example, the "U"-shaped ventilation groove forms a channel that runs through from front to back; the "U"-shaped ventilation grooves of the left and right liner units are aligned with the gap between the two liner units on the top to ensure the ventilation effect.
[0021] The helmet body fixing system includes: a helmet gravity adjustment band, a helmet body connection band, a chin rest, a head circumference fixing band, and a back pillow pad. The back pillow pad is provided with a ventilation structure, which can improve comfort and breathability;
[0022] As an example, the breathable structure includes: Oxford cloth fixed with a head circumference adjustment knob, 45° cross-fixed webbing, a "W"-shaped spacer pad, and breathable mesh fabric; where:
[0023] The 45° cross-fixed webbing is as follows: Two front webbings are made into a helmet center of gravity adjustment strap, with the lower end connected to the mandible support. Two rear webbings are helmet body connection straps, respectively fixed to the left and right sides at the rear of the helmet.
[0024] The "W"-shaped spacer pad has an inverted trapezoidal shape, with its arc conforming to the curvature of the back of the head, and is provided with breathable through holes in the middle.
[0025] Advantages of the present utility model:
[0026] ① Through the special structural design of ventilation grooves and ventilation holes in the buffer layer and comfort layer of the cushion, the contact area between the cushion and the head is reduced, good ventilation is formed, the breathability of the helmet is improved, making up for the shortcomings of poor breathability and easy to cause stuffiness of common cushions. At the same time, the structural design of the porous flexible material blocks and breathable mesh fabric in the comfort layer further strengthens the air circulation and improves the thermal and wet comfort when wearing the helmet.
[0027] ② The design of ventilation grooves and ventilation holes combined with the breathable mesh fabric for encapsulation is conducive to the volatilization of sweat and reduces the growth of bacteria. At the same time, the use of the bonding method of Velcro enables the disassembly of the cushion, which is convenient for cleaning and replacement.
[0028] ③ The special breathable structure provided in the back pillow pad of the helmet body fixing system, while realizing the functions of head circumference adjustment and helmet body fixing, isolates the head circumference adjustment knob and the head through the spacer pad design, increasing comfort and breathability.
