Description

  The present invention relates to an omnidirectional impact-preventing structure for a safety helmet, in particular, a combination design in which a case body and an elastic carrier are combined by applying a (buffer foam) filling body. The present invention relates to a technique for forming a composite structure of the entire structure by matching the cross-girder-like structure section having the structure.

The impact resistance filling body formed by combining a foam material with a plastic case body and heated, and the helmet structure in which the foam filling body is tightly covered and adhered by the plastic case body are conventional techniques.
For example, Patent Document 1 “Safety Helmet with A Shell Injected Thermoplastics And Method for The Manufacture of Said Helmet”, Patent Document 2 “Helmet Manufacturing Method”, etc.

  The structure of this type of safety helmet is to resist shock and impact of external objects with an external plastic bag, and at the same time, when shocked by external force is applied to the foam filling, it provides shock buffering and distributed transmission. Provide and achieve user head protection effect.

Conventionally, a thin layer liner is usually installed at the position of the innermost layer of the conventional helmet to form a cushion layer between the helmet and the wearer's head.
Many of the thin layer liners are fabric products.
The structural characteristics and application issues of this type of thin-layer liner are not only to expand the trouble of the assembly process by installing a separate thin-layer liner inside the safety helmet.
Other material properties and thin-layer structures cannot increase the comfort of user wear or reduce the sultry heat of prolonged wear.

  Furthermore, as those skilled in the art know, if the structure and characteristics of the thin liner are limited, the coverability and adhesion between the safety helmet and the wearer's head should be increased as much as possible. In practice, based on the size of the wearer's head, there is no choice but to provide helmet products of different standards, which clearly increases the manufacturing costs.

  Another problem in the structural form and application of this type of safety helmet combination thin layer liner is that even though the conventional technology can provide helmet products of different sizes, it varies depending on the helmet and thin layer liner. The entire contour of the wearer's head or the curved surface of the head cannot be reliably covered and adhered.

That is, conventional safety helmets can provide different sizes or standards, but cannot perfectly match the contours of the entire head in the three-dimensional direction of the wearer's head or the curved surface of the head. As a result, the coverability and the degree of adhesion to the wearer's head are reduced.
This adversely affects the protection and safety of the helmet head when the wearer's head is impacted by external force.

In the design technique of the structure and manufacturing surface of the conventional safety helmet disclosed in the above-mentioned patent document, there is a problem in actual use in the combination structure of the outer case body or the plastic bag and the inner structure body and the thin layer liner. .
Newly designed internal combination structure of case body or plastic bag, foam material layer and thin layer liner, and the structure design meets the condition that manufacture is simple, but unlike the conventional one, it is ideal If it is possible to provide protection and comfort for wearing and change the transmission distribution form of external impact force, the drawbacks of the prior art can be improved.

U.S. Pat. No. 4,466,138 Taiwan Patent No. 85101810 specification

The inventor has realized that in the conventional structure, it is necessary to consider the troublesomeness of the process in which the thin-layer liner has to be assembled separately and the situation where the comfort of wearing cannot be effectively increased.
In addition, the structure of the safety helmet is elastically matched to the contour of the wearer's head or the curved surface and size of the head in the three-dimensional direction, thereby improving the overall coverage and adhesion to the head of the safety helmet. The impact force of each external type (positive direction or lateral direction) is distributed and transmitted to each area of the entire helmet by the internal structure, and it is easy to manufacture and matches the design trend of making the helmet compact. It is necessary to consider the necessity of the structural form.
However, these problems are not taught or specifically disclosed in the above-mentioned patent documents.

  The present invention is a combination of a case body, a packing body wrapped in the case body, and an elastic carrier, and the elastic carrier has a wall forming a frame structure and a plurality of grid-shaped structure sections having a geometric outline defined by the walls. The projecting wings are formed in the peripheral area of the ridge-like structure area (or in the central direction toward the cross-girder-like structure area). The sub-areas connected to each other are partitioned, whereby the filling body is connected to the case body and the elastic carrier to form an overall form, and the first section (or wall) is directed toward the filling body (inside). Under the conditions to form a stretched structure and increase the overall structural strength, it responds to the elastic carrier, causing a different degree of flexible deformation action according to the difference in head profile, covering the entire head, buffering Transmits external impact force while absorbing, increasing wearing comfort and adhesion About omnidirectional shock prevention structure of the safety helmet of the operation and effect.

The omnidirectional impact prevention structure of the safety helmet according to the present invention has a filler.
A part of the material of the filler enters at least the first section and / or sub-area of the elastic carrier, and the filler and the elastic carrier are bonded or bonded (the bonding is performed when the filler material is the first section, This means that the sub-area or wing part and the wall structure form are passed or connected to form a whole structure, thus improving the troublesome process of the prior art in which the thin liner has to be assembled separately.
Moreover, the mechanism or action of mutual support between the elastic carrier and the filler is established.
When the case body and the filling body receive an external impact force and produce a buffer absorption action, the elastic carrier acts to disperse and transmit the impact force.

Substantially, the lower wall of the second section forms a structure similar to the elastic section due to the structural form in which the first section and / or sub-area is connected to the filler, and the head in different head sizes and three-dimensional directions is formed. Based on the contour of the shape or the curved surface of the head, different degrees of flexible deformation occur.
In this way, the wearer's head can be elastically contacted, the wearer's head can be comfortably covered, and the entire surface coverage and adhesion can be improved, and the structural defects of the conventional helmet and / or thin layer liner can be improved.

In particular, the lower wall of the second section causes different degrees of flexible deformation, and when it is in full elastic contact with the wearer's head, the cross-shaped structure section (or the second section) and the wearer's head The air chamber structure formed between the two forms a function similar to that of a flexible suction cup.
The elastic carrier is based not only on the wearer's different head shape or curved surface of the head, but also easily adheres entirely to the wearer's head, and the air chamber reacts to external impact force, It acts to buffer and absorb force.

In the omnidirectional impact prevention structure of the safety helmet according to the present invention, at least one elastic structure and / or subcase is provided between the inner surface of the case body and the filler.
A plurality of combination parts are installed in the upper area and / or the lower area of the elastic structure.
The main case body and / or the sub case is formed with a pivotal portion and is combined corresponding to the combination portion described above.
Accordingly, the filler is connected to the elastic structure, the main case body, and / or the sub case to form an entire form.
Under the condition of increasing the strength of the entire structure, the multi-layer structure, omnidirectional buffering, absorption, external impact force (or impact positive direction force, rotational torque) transmission are realized.

In the omnidirectional impact prevention structure of the safety helmet according to the present invention, the cross-shaped structure section of the elastic carrier extends in the direction of the filling body (or case body) to form an elastic column.
The elastic column has a connecting end and a free end extending in the direction of the filler.
A connecting surface is formed between the connecting end and the upper wall of the cross-shaped structure section, and the free end has a contact surface.
The width of the cross section of the elastic column is larger than the thickness of the wall or the upper wall (or the width of the cross section), and when the elastic column reacts to a larger external impact force, a breaking point is formed on the connecting surface. .

  The omnidirectional impact prevention structure of the safety helmet according to the present invention covers the entire head and transmits external impact force while absorbing the buffer, thereby achieving the effects of improving the comfort and closeness of wearing. it can.

[Example 1]
As shown in FIGS. 1, 2, and 3, the omnidirectional impact prevention structure of the safety helmet of the present invention will be described using an embodiment of a safety helmet for sports.
The safety helmet is an American football, hockey helmet, construction helmet, mountaineering helmet, riding helmet, or half-face or full-face helmet for cycling, motorcycle, skiing, car racing, etc. The assembly 100 is configured by having a combined structure of the filler 30 and the elastic carrier 40 wrapped in the case body 10.

In the following description, the upper, upper, lower, lower, or bottom portions have reference directions as the directions displayed in the drawings.
Moreover, the member which goes to a wearer direction is defined as an inner surface or an inner side, and the direction opposite to a wearer or the member which leaves | separates is defined as an outer surface or an outer side.

In the embodiment, the case body 10 is made of a plastic material and has an inner surface 11 facing the wearer and an outer surface 12 opposite to the wearer.
The inner surface 11 of the case body is in contact with or connected to the filling body 30.
A protective layer 60 is disposed on the outer surface 12 of the case body.
The protective layer 60 is manufactured using glass fiber, carbon fiber material, or a similar material, and reinforces the structural strength of the case body 10.

As shown, the elastic carrier 40 is located at the innermost layer location of the safety helmet or assembly 100 (ie, the area away from the case body 10) and is coupled to the lower area 31 of the filler 30.
The elastic carrier 40 selects a flexible or elastic material (for example, rubber or the like) and forms a shape similar to a honeycomb structure.
The lower area 31 is located at a location away from the inner surface 11 of the case body.

As shown in the figure, the elastic carrier 40 includes a wall 49 forming a framework structure and a plurality of cross-girder-like structure sections 45 in which the walls 49 define a cross section (a honeycomb structure having a hexagonal outline, for example). Have.
The wall 49 faces both sides or the peripheral area (or the peripheral area of the cross-girder-like structure area 45) and forms a protruding wing 46.
Thereby, the cross-girder-like structure section 45 divides the sub-area 43 connected between the first section 41 and the second section 42 and the first section 41 and the second section 42.
Moreover, the cross section of the first section 41 or the second section 42 is larger than the cross section of the sub-area 43, and the wing 46 (or the frame structure) located on both sides of the wall 49 and the wall 49 has a “++++” cross section. Form the structure jointly.
Thus, the elastic carrier 40 makes full contact with or wraps around the wearer's head H (see FIG. 3 or FIG. 4).

In the embodiment employed, the elastic carrier 40 has a frame 44 that forms in its bottom area.
The frame body 44 extends to the outside of the elastic carrier 40 (or in the direction of the case body 10), forms a U-shaped cross-sectional structure, and encloses the case body 10 and the foam filler 30 so as to be connected.

A wall 49 of a position or section corresponding to the first section 41 and the second section 42 is defined as an upper wall 47 and a lower wall 48.
The filling body 30 connects the case body 10 and the elastic carrier 40 by forming a mold or a molding module so as to form an overall form, thereby forming the safety helmet assembly 100.

In detail, the material (buffer foam) material of the filler 30 at least enters the first section 41 and / or the sub-area 43 of the elastic carrier 40, whereby the filler 30 and the elastic carrier 40 are bonded or bonded. (Bonding means that the material of the filling body 30 passes through the structural form of the first section 41, the sub-area 43 or the wing portion 46, and the wall 49, or is filled and connected). The section 41 (or the upper wall 47) forms a structure that extends in the direction of the filler 30 (inside).
In this way, the cumbersome process of the prior art where a thin liner has to be assembled separately can be improved.

Preferably, a part of the material of the filling body 30 fills the entire first section 41 and the sub area 43 and is connected to the upper wall 47 and the wing portion 46.
In addition, due to the structure and material characteristics of the elastic carrier 40 (combined filler 30), when the elastic carrier 40 receives an external impact force (for example, a positive force or shear force), elastic deformation and / or rotational deformation occurs. Absorb and absorb external impact force and speed.

As shown in FIGS. 4 and 5 showing a state in which a part of the material of the filling body 30 enters the first section 41 and / or the sub-area 43, the elastic carrier 40 (that is, the first section 41 and / or the sub-area 43). The density of the filling body 30 located in the area 43) is smaller than the density of the filling body 30 located in the outer area of the elastic carrier 40.
Different foam structure densities constitute different acting force (or impact force) transmission, dispersion and buffer absorption effects.

The elastic carrier 40 and the filler 30 also constitute a mutual support mechanism or action depending on the tissue configuration in which the filler 30 is bonded to the elastic carrier 40.
When the case body 10 and the filling body 30 receive an external impact force and produce a buffer absorption action, the elastic carrier 40 produces an action of dispersing and transmitting the impact force.
As a result, the assembly 100 achieves functions such as full or multi-directional buffering, rotational torque absorption, external impact force transmission, and the like under conditions that increase the overall structural strength.

Due to the structure configuration in which the first section 41 and / or the sub-area 43 is coupled to the filler 30, the lower wall 48 of the second section 42 forms a structure similar to the elastic section, and has a different head size, three-dimensional. Based on the head profile of the direction or the curved surface of the head, different degrees of flexible deformation are produced (for example, the situation shown in the solid line portion in FIG. 5), elastically contacting the wearer's head H, and the wearer's head The comfort of the part H, the whole surface cover property, and the adhesion degree (or adhesion area) can be increased.
In this way, the structural defects of conventional helmets and / or thin layer liners can be improved.

In particular, the lower wall 48 of the second section 42 has different degrees of flexible deformation action, and when it is in full elastic contact with the wearer's head H, the cross-shaped structure section 45 (or the second section 42). The air chamber structure formed between the wearer's head H and the wearer's head H forms an action similar to that of a flexible suction cup.
The elastic carrier 40 not only easily adheres to the wearer's head H entirely on the basis of the wearer's different head profile or curved surface of the head, but also more ideal protection and safety than conventional techniques. In addition, the air chamber reacts to the external impact force and acts to buffer and absorb the external impact force.

  As shown in FIGS. 4 and 5, in the modified embodiment, the elastic structure 20 and / or the subcase 50 is installed between the case body 10 and the filling body 30 to form a multilayered and floating combination structure. .

“Floating” means that a relative movement and / or rotation situation occurs within the assembly 100 when the member reacts to an external force.
For example, when the elastic structure 20 reacts to an external action force, the main case body 10 and the sub case 50 are moved relative to each other and / or rotated to generate a motion such as compression and elastic deformation.

  Preferably, the case body 10 and the filling body 30 (and / or the elastic structure 20 and the sub case 50) are provided with a gap between the pore structure (not shown) or the filling material 30 and the foamed material, and the elastic carrier 40. The air convection action of the assembly 100 is increased, and the situation in which the user feels sultry by wearing for a long time can be reduced.

In the embodiment to be employed, the elastic structure 20 selects and manufactures a flexible or elastic material such as polystyrene (EPS), vinyl acetate copolymer (EVA), rubber or the like.
Therefore, the elastic modulus (or deformation amount) of the elastic structure 20 is larger than the elastic modulus (or deformation amount) of the filler 30, and the deformation of the elastic structure 20 and the shock absorbing effect can be expanded.

As shown, the elastic structure 20 defines or has an upper section 21 and a lower section 22.
A plurality of combination parts 23 are installed in the upper area 21 and the lower area 22 of the elastic structure 20, respectively.
A concave tub 24 is formed in the combination part 23 of the elastic structure 20, and the combination part 23 is partitioned into a geometric outline (for example, a hexagonal outline), and each combination part 23 is formed adjacent to the honeycomb structure. The

In the embodiment to be adopted, the subcase 50 is manufactured by adopting a plastic material, and has an inner surface 51 facing the wearer and an outer surface 52 opposite to the wearer.
The sub case 50 corresponds to a mold or a molding module, so that the filler 30 is connected to the inner surface 51 of the sub case.
The inner surface 11 of the case body and the outer surface 52 of the sub case are in contact with or connected to the upper area 21 and the lower area 22 of the elastic structure 20, respectively.

As shown in the drawing, (elastic) pivot portions 13 and 53 are formed on the inner surface 11 of the case body and the outer surface 52 of the sub case, respectively.
The case body pivot part 13 and the sub case pivot part 53 have protruding walls 14 and 54, respectively, define the pivot part 13 (or 53), and form a geometric outline (for example, a hexagonal outline). To do.
Thereby, each pivotal part 13 (or 53) is formed adjacent to the honeycomb structure, and is combined or engaged with the combination part 23 of the elastic structure 20.

In one embodiment, the elastic structure 20 is provided with a through hole 25 and disposed on the combination part 23.
The holes 25 can be filled with fluid, thereby adjusting or modifying the elastic modulus of the elastic structure 20.

  As shown in FIGS. 6 and 6A, when an external impact force (or positive direction force) impacts the assembly 100, the case body 10, the elastic structure 20, the filling body 30, and / or the sub case 50 (on the elastic carrier 40). Correspondingly, different degrees of elastic deformation occur (see the situation shown in the solid line in FIG. 6), and the speed of the external impact force is reduced, and the external impact force is jointly shared, creating a buffer absorption effect, and the external impact force. Are distributed in all directions (or in multiple directions) and transmitted to the filling body 30 and / or the entire assembly 100.

  After the external impact force disappears, the action of restoring the initial combination position as much as possible can be obtained by the structural characteristics of the filler 30 (or the elastic structure 20, the subcase 50) and the elastic carrier 40 (dotted line K in FIGS. 6 and 6A). Situation).

7 and 7A, when an external impact force (or shear force) gives an impact to the assembly 100, the case body 10, the elastic structure 20, the filling body 30, and / or the sub case 50 (corresponding to the elastic carrier 40). And undergoing different degrees of elastic deformation and rotational deformation), the flattening deformation form in response to the rotational acceleration and shearing force of the external impact force is reduced.
In addition, the external impact force is jointly borne, a buffer absorbing action is generated, the external impact force is distributed in all directions (or multiple directions), transmitted to the entire filling body 30 and / or the assembly 100, and absorbed and absorbed. Decreases acceleration and rotational torque that generate impact force.

  After the external impact force disappears, the action of the initial combination position is recovered through the elastic deformation mechanism of the elastic structure 20 (and / or the filling body 30) and the elastic carrier 40 (the situation shown by the dotted line K in FIGS. 7 and 7A). .

  Between the case body 10 and the sub case 50, a plurality of or a plurality of layers of the elastic structure 20 or the assembly 100 are installed, and correspond to the structural form of the plurality of or a plurality of layers of the elastic carrier 40.

As shown in FIGS. 8, 9, and 10, which is one modified embodiment of the elastic carrier 40, the first section 41 (or the upper wall 47) of the cross-girder-like structure section 45 is the filling body 30 (or the case body 10). The elastic column 70 is formed by stretching in the direction.
The elastic column 70 has a connecting end 71 connected to the upper wall 47 and a free end 72 extending in the direction of the filler 30.
The free end 72 has a contact surface 73.
The contact surface 73 forms a concave arc surface structure, and a connecting surface 74 is formed between the connecting end 71 and the upper wall 47.

  In the embodiment to be adopted, the width of the cross section of the elastic column 70 is larger than the thickness of the wall 49, whereby the elastic acting force of the elastic column 70 can be expanded.

As shown in FIGS. 10 and 11, after the elastic column 70 passes through the filler 30 (and / or the elastic structure 20), the contact surface 73 is joined to the inner surface 11 of the case body 10, and the free end 72 ( Alternatively, an air chamber structure is formed between the contact surface 73) and the inner surface 11 of the case body.
The air chamber structure forms a structure similar to a shock absorber, reacts to an external impact force, causes a flexible deformation and / or rotational deformation, and acts to buffer and absorb the external impact force.

  As shown in FIGS. 12 and 12A, when an external impact force (or a positive direction force) gives an impact to the assembly 100, the elastic column 70 of the elastic carrier 40 passes through the case body 10, the elastic structure 20, and the filling body 30. Correspondingly, different degrees of elastic deformation are generated, the speed of external impact force is reduced, the external impact force is jointly borne, a buffer absorption action is created, and the external impact force is distributed in all directions (or multiple directions) , Transmitted to the filler 30 and / or the entire assembly 100.

  After the external impact force disappears, the initial combination position can be restored as much as possible by the structural characteristics of the filler 30 (or the elastic structure 20), the elastic carrier 40, and the elastic column 70 (indicated by the dotted line K in FIGS. 12 and 12A). Situation shown).

As shown in FIG. 13 and FIG. 13A, when an external impact force (or shear force) gives an impact to the assembly 100, the case corresponds to the elastic carrier 40 via the case body 10, the elastic structure 20, and the filling body 30, and the elastic column. 70 different degrees of elastic deformation and rotational deformation are produced, and the transition deformation form in response to the rotational acceleration and shear force of the external impact force is reduced.
In addition, the external impact force is jointly borne, a buffer absorbing action is generated, the external impact force is distributed in all directions (or multiple directions), transmitted to the entire filling body 30 and / or the assembly 100, and absorbed and absorbed. Decreases acceleration and rotational torque that generate impact force.

  After the external impact force disappears, the action of the initial combination position is recovered through the elastic deformation mechanism of the filler 30 (and / or the elastic structure 20), the elastic carrier 40, and the elastic column 70 (FIG. 13, FIG. 13A, dotted line K). Situation).

As shown in FIGS. 14 and 14A, when a relatively large external impact force (or shear force) gives an impact to the assembly 100, the elastic carrier 40 and the elastic column pass through the case body 10, the elastic structure 20, and the filling body 30. Corresponding to 70, elastic deformation and rotational deformation of different degrees are generated, and the transition deformation form in response to the rotational acceleration and shearing force of the external impact force is reduced.
In addition, the external impact force is jointly borne, a buffer absorbing action is generated, the external impact force is distributed in all directions (or multiple directions), transmitted to the entire filling body 30 and / or the assembly 100, and absorbed and absorbed. Decreases acceleration and rotational torque that generate impact force.

The elastic carrier 40 (and / or the elastic column 70) envelops different head-shaped contours or curved shapes of the head of the wearer, and produces the following actions.
1. The elastic carrier 40 forms a cross-shaped structure section 45 having a honeycomb structure, and the continuously arranged lower walls 48 have different degrees of flexible deformation based on different head contours or curved surfaces of the head. It occurs and comes into contact with the form of the head H, whereby the elastic carrier 40 wraps around the wearer's head H completely and reliably. Therefore, since the entire head cannot be securely adhered to the wearer's head, the belt of the helmet is tightened or loosened, and the disadvantages of the conventional technology helmet that affects the helmet's protection or safety situation are reduced to the minimum. Be made.
2. The elastic carrier 40 forms a support structure 45 having a honeycomb structure and supports the elastic carrier 70, and the elastic column 70 has a relatively large flexible deformation due to an action force (or shear force) generated in response to a relatively large external impact force. And / or rotational deformation (or forming a break point between the elastic column connecting surface 74 having a relatively large width and the upper wall 47 having a relatively small cross-sectional width of the cross-like structure section 45), and the case body 10, Corresponding to the elastic structure 20, a relatively large relative motion is generated in the assembly 100 (for example, movement or rotation), most of the external impact force is buffered and absorbed, and an acceleration and an acting force amount at which shear force or rotational torque is generated are obtained. Reduced and transmitted to the entire filling body 30 and / or the assembly 100 with omnidirectional (or multidirectional) dispersion, preventing external impact force from being transmitted to the wearer's head H, and providing a full protective effect Formation to. Further, through the elastic recovery mechanism of the elastic structure 20 (and / or the filler 30), the elastic carrier 40, and the elastic column 70, the external acting force and speed are further buffered and absorbed.

The omnidirectional impact prevention structure of the safety helmet according to the present invention has the following advantages over the conventional technology.
1. The combination structure of the case body 10, the filler body 30, and the elastic carrier 40 has already been newly designed. For example, the elastic carrier 40 has a wall 49 that forms a frame structure, and forms a plurality of cross-girder-like structural sections 45 and wing portions 46 that are installed in the peripheral area of the cross-girder-like structural section 45, thereby Defines a sub-area 43 connected between the first ward 41 and the second ward 42 and the first ward 41 and the second ward 42. Thereby, a part of the material of the filler 30 enters at least the first section 41 and / or the sub-area 43 of the elastic carrier 40, and thus the portion such as the connection between the filler 30 and the elastic carrier 40 is the conventional safety. It is clearly different from the structure of the helmet.
2. Due to the structure and material characteristics of the elastic carrier 40 (combined filler 30), when the elastic carrier 40 reacts to an external impact force (for example, positive direction force or shear force), elastic deformation and / or rotational deformation occurs, and external Absorbs shock force and speed. Due to the structural configuration in which the first section 41 and / or the sub-area 43 of the elastic carrier 40 are coupled to the filler 30, the lower wall 48 of the second section 42 forms a structure similar to the elastic section, and has a different head size, head Based on the contour of the shape or the curved surface of the head, different degrees of flexible deformation are produced, making it easy to make elastic contact (or close contact) with the wearer's head H, which is more ideal than conventional techniques. And produce safety. Alternatively, by forming an air chamber structure between the cross-girder-like structure section 45 (or the second section 42) and the wearer's head H, the assembly 100 assists the action of buffering and absorbing the external impact force. The comfort, coverability and adhesion (or adhesion area) of the part H can be strengthened, and the troublesome process of the conventional technology in which a thin-layer liner has to be assembled separately, the coverability and comfort of the user are effective. It is possible to clearly improve the situation where it cannot be raised.
3. The cross-shaped structure 45 (or the upper wall 47) of the elastic carrier 40 forms a structural form of the elastic column 70, and the elastic column 70 passes through the filler 30 (and / or the elastic structure 20) and then contacts the contact surface 73. Is joined to the inner surface 11 of the case body 10 to form an air chamber structure. In response to an external impact force, the elastic column 70 causes a flexible deformation and / or a rotational deformation, and assists in buffering and absorbing the external impact force of the assembly 100.
4). In addition, the structural strength of the case body 10 is clearly improved by the structural structure in which the case body 10 is coupled to the filling body 30 (or the elastic structure 20 and the subcase 50) and the elastic carrier 40, and the structure is easy to manufacture and the helmet compact. To meet the requirements of computerized design, provide relatively ideal protection and multi-directional buffer capacity, and modify the transmission distribution form of external impact force.
