In special work post and field operation, (protective helmet or soldier used such as building, fire-fighting domain makes protective helmet The tactical protection helmet) it is the individual protective equipment for protecting incidence to escape injury that must be worn.

For example, protective helmet can effectively prevent bullet, fragmentation from penetrating on station, soldier's injures and deaths are reduced.When shellproof protection When the helmet faces bullet hits or external weight shock, energy will be passed to wearer's head, easily cause scalp abrasion, brain shake It swings and head, fracture of cervical spine equivalent damage.

Therefore protective helmet needs to add buffer pad to protect wearer safe.Wherein, protective helmet shell can divide Dissipate impact energy, and pad can play the role of absorb impact energy, meanwhile, liner also with shock resistance, compression, air-moisture-permeable, The functions such as heat transfer, vibration damping.

Currently, protective helmet liner mostly uses greatly single material, high speed and low velocity impact cannot be considered in terms of.Also there is part lining Pad uses two kinds of foamed material simple superposition, can only lay particular emphasis on high speed impact and low speed collision, not can guarantee the impact of middling speed but Buffering effect, and wear uncomfortable.If foamed material hardness is higher, low speed collision absorbent properties are poor and wearing is not relaxed It is suitable；If foamed material hardness is lower, when facing bullet high speed impact, enough cushion performances can not be provided, head is caused to hold Craniocerebral injury is caused vulnerable to impact.

In view of, in the example of the utility model, inventors herein propose it is a kind of can be used in make protective helmet lining Pad 100.The liner 100 has desired performance, can be used for improving the using effect of protective helmet.For example, wearing above-mentioned anti- Helmet is less susceptible to that excessively sultry sense occurs, especially during the broiling summer or sultry environment and space.

Of course, it should be appreciated that substrate in the utility model example in addition to for the liner as protective helmet it Outside, it can be utilized to as other purposes and used.For example, liner 100 is normally used as interlayer, interlayer etc..

More full and accurate elaboration is carried out to the liner 100 in the utility model embodiment below with reference to attached drawing.

Refering to fig. 1 to Fig. 5.

Liner 100 is a kind of layer structure provided by the present embodiment, and normally its by as a kind of laminated structure And it is manufactured.Of course, liner is 100 in addition to being made as laminated structure, also can according to need be made as other shapes or Construction can specifically carry out the adjustment and change of appropriateness according to the demand of its application.

For example, when liner 100 is used as anti-collision wall in use, it, which is made as, has the plate of suitable thickness.Tool In the application of body, using two metal plates (such as stainless steel plate), and liner 100 above-mentioned is arranged between two metal plates.

It has been observed that liner 100 is layer structure, thus its with multiple and different functional layer structures, be multilayer.Liner 100 number of plies can according to need and be selected, without making necessary restriction.It should be appreciated, however, that liner above-mentioned 100 number of plies is the quantity of the different layers in its structure.Substantially, according to function distinguishing, the number of 100 different function layer is padded Amount is to be pre-designed and determined.In the present embodiment, liner 100 has 7 functional layers.Wherein each functional layer can be with It is made of multiple layers in varying numbers.For example, water-proof function layer, one layer can be, can also be with two layers or three layers etc..Wherein, should One layer, two layers and three layers each means the material layer with identical material.

In example, liner 100 includes the first clad 107, the first waterproof layer 106, comfort liner 105, transition zone 104, delays Rush layer 103, the second waterproof layer 102 and the second clad 101.Above seven layers are arranged successively, and are through-thickness successively layers Laying up is set.In other words, by 107 to the second clad 101 (or 101 to the first clad 107 of the second clad) of the first clad Constitute the thickness direction of liner 100.

Also based on this, 100 shock resistance that can play of liner is also mainly by padding 100 pairs come to thickness direction Impact force play absorption and unloading to realize.Therefore, in order to play preferable protection effect, it is being made as protective helmet When, liner 100 is shaped as curved surface (such as arcwall face, ellipsoid, spherical surface) so as to bear the impact of multiple directions and hit Hit power.

Contact can be closely laminated in each functional layer in liner 100.It can be in a kind of example, between each functional layer It is realized by being located at the constraint of outermost first clad 107 and the second clad 101.Alternatively, between each functional layer Bundled fixed is carried out in a manner of sewing the silk thread in impenetrating thickness direction, to realize the close contact between adjacent layer.Or Person, (can be the contact in its whole face in the position to contact with each other, be also possible to connecing for part face between different functional layers Touching) pass through gluing/bonding/bonding way realization connection.

It should be pointed out that liner 100 may be made as curve form it has been observed that under different use environments, because This pays the utmost attention to its shape and application scenarios when selecting to be mutually connected between adjacent functional layer.

Since the first clad 107 and the second clad 101 are the outermost layers for padding 100, when being used for protective helmet, two One of person can be related to and human contact, therefore one or both of the first clad 107 and the second clad 101 are adopted It is made with anti-biotic material.In a kind of example of the utility model, the first clad 107 is the component contacted with head, It is therefore preferable that the first clad 107 is made using antibacterial flannelette.Optionally, in a kind of alternative example, anti-biotic material is Antibacterial flannelette.

As its name suggests, one or both of the first waterproof layer 106 and the second waterproof layer 102 are waterproof ventilated membranes.That is, first First, the first waterproof layer 106 and the second waterproof layer 102 are waterproofs.In actual use, two waterproof layers are mainly used for preventing sweat It is permeated in liner 100.For example, one or both of the first waterproof layer 106 and the second waterproof layer 102 are waterproof ventilated membranes. Further, based on ventilative requirement, waterproof ventilated membrane is formed using polyurethane material.

Based on the above, clad and waterproof layer are relatively thin structure sheafs, therefore, mainly as liner 100 Additional function functional layer, and to the main protecting against shock and Anti-knocking of liner 100 without requiring with biggish contribution.Change speech It, does not need the needs based on protecting against shock and Anti-knocking and clad and waterproof layer is required to have greater hardness and intensity, It does not need the two to allow for through deformation absorbing impact force, and slowly discharges the energy gathered yet.

Preferably, comfort liner 105, transition zone 104, buffer layer 103 can be with as 100 main anti-collision structures of liner Play the role of collectively as entirety desired.Firstly, the hardness of three gradually changes.Specifically, buffer layer 103 is hard , transition zone 104 is semi-rigid, comfort liner 105 is soft.When liner 100 is used for protective helmet, comfort liner 105 It is the part on neighbouring head, and buffer layer 103 is the part of neighbouring protective helmet inner wall.Therefore, when weight or alluvium strike When protective helmet, buffer layer 103 can resist weight and it is avoided further to break through liner 100 and injure head.And transition zone 104 and comfort liner 105 then can by deformation absorb impact energy, its impact force partly be laid down, thus mitigate to neck Injury.

In addition, preferably, transition zone 104a has groove 1041a from comfort liner 105 to 103 direction of buffer layer that invaginate from, Comfort liner 105 has air hole 1051, and air hole 1051 is connected to groove 1041a.Due to such structure setting, transition zone 104a and the cooperation of comfort liner 105 can play preferable permeation functions.Simultaneously as hole configurations in this way can also be in certain journey The weight for mitigating liner 100 on degree, can also correspondingly mitigate the weight of protective helmet.In addition, groove 1041a and air hole Air in 1051 can also play the role of air cushion.In another example, transition zone 104b can also be set as needed The shrinkage pool 1041b of other forms.

Alternatively, comfort liner 105 can be made using emulsion foaming material or flexibel polyurethane；Transition zone 104 It is made using semi-rigid foamed material；Buffer layer 103 is made using hard foam.Aforementioned hard hair therein Foam material is also possible to polystyrene foam or hard polyurethane foams.

For generally, in the exemplary liner 100 of the utility model, waterproof layer water-proof sealing, the deformation of transition zone 104 are inhaled Energy, 105 soft comfortable of comfort liner, the anti-high speed impact of buffer layer 103.

In a kind of example, buffer layer 103 is made of hard foam, such as polystyrene (PS) foam, hard polyurethane Ester (PUR) foam, has the function of anti-high speed impact.Transition zone 104 is made of semi-rigid foamed material, is liner 100 Energy-absorbing section is deformed, 100 deformation energy-absorbings are padded when being impacted.Comfort liner 105 is made of flexible foamed material, such as latex Foamed material, flexibel polyurethane (PUR) have the function of protecting low speed impact.105 better softness of comfort liner increases contact Area reduces head pressure, can adapt to different head dummys.Meanwhile comfort liner 105 uses air hole structure, has gas permeability.It is anti- Water layer has the function of waterproof and breathable such as polyurethane film (TPU) using waterproof ventilated membrane, and sweat can be prevented to enter liner Inside 100, liner 100 is prevented to be contaminated and foul.Space between transition zone 104 and comfort liner 105 forms micro climate, leads to The air hole 1051 and head for crossing comfort liner 105 form ventilation channel, reduce feeling of oppression and heat.Clad is made of antibacterial flannelette, Inhibit bacterial growth while absorbing sweat rapidly.
