Description

Technical Field

[0001] The present invention belongs to the technical field of protective gear, and particularly relates to a connection structure and a full-coverage bulletproof helmet. Background Art

[0002] The trend of the continuous growth of military forces in various countries around the world is inevitable. At the same time, the power of military weapons on the battlefield is also constantly increasing. During the explosion of these weapons, a large number of explosion fragments will be generated, causing serious trauma to the heads and faces of soldiers. However, traditional bulletproof helmets can only protect the top of the head, with insufficient head protection area, and the eyes and jaw are still not within the protection range. Therefore, on the battlefield, soldiers will still be directly damaged by explosion fragments, bullets or shrapnel. In the face of the above problems, it is urgent to install a bulletproof face mask and goggles on the bulletproof helmet to protect the face, eyes and jaw. However, at present, there is still a lack of a full-coverage, integrated bulletproof combat helmet that can perfectly match the face mask and glasses. In addition, the full-coverage bulletproof helmet not only needs to achieve comprehensive head protection, but also needs to be quickly disassembled and assembled to meet tactical actions such as holding a gun and shooting, and even requires one-handed operation to improve the combat efficiency during the battle.

[0003] At present, some relevant technical personnel have done some research in this field. Patent CN114383469A introduces a face mask for a bulletproof protection helmet. Through the action of the face mask plate and the fragment protection lip, it has an effective anti-impact effect. The face mask is fixedly connected to and longitudinally rotated with the helmet body by means of bilateral bearings, but the installation and disassembly of the bulletproof face mask need to be completed with the help of corresponding tools, and it does not have the quick installation and disassembly functions of the bulletproof face mask of the present invention. Patent CN112869283A introduces a double-layer face mask protection helmet and its manufacturing method. The face mask adopts a double-layer structure of upper and lower pieces. The upper face mask is used to protect the front of the head, and the lower face mask protects the jaw part. Although this design can obtain more protection area, the disassembly and assembly of the inner and outer two-layer face masks are required, which limits its application in the field of individual combat. Patent CN108168372A introduces a bulletproof helmet and its face mask. This technology designs an installation plate and an installation bracket, which are arranged on both sides of the bulletproof face mask. By using the buckles on the installation plate, the simultaneous fixation of both sides of the face mask is realized. This face mask requires both hands to operate the installation plates on both sides at the same time, which affects the combat efficiency of individual combat personnel and limits its application in the field of individual combat. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defect that in the prior art, both hands are required to operate the installation plates on both sides of the face mask, which affects the combat efficiency of individual combat personnel and limits its application in the field of individual combat, and to provide a connection structure and a full-coverage bulletproof helmet.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] A connection structure, characterized in that it comprises:

[0007] The first connecting part comprises a first magnetic member arranged on a first connecting surface of the first connecting part and an active buckle capable of sliding back and forth along a straight line direction parallel to a plane where the first connecting surface is located under the action of a driving member;

[0008] A second connecting portion, comprising a second magnetic member and a limiting groove arranged on a second connecting surface of the second connecting portion;

[0009] The first connection surface and the second connection surface are arranged opposite to each other and can be adsorbed and attached to each other under the action of the first magnetic member and the second magnetic member;

[0010] When the first connection surface and the second connection surface are fitted and connected, the limiting groove is located on the sliding path of the active buckle, and the active buckle can slide into the limiting groove and be limited in a direction perpendicular to the first connection surface.

[0011] In this solution, the above structure is adopted, and the connection structure includes a first connection part and a second connection part that can be detached from each other. The first connection part and the second connection part can be fixed to the two parts to be connected respectively. The two parts to be connected are assembled together through the cooperation of the first connection part and the second connection part. When it is necessary to remove, it is only necessary to operate the connection structure to make the first connection part and the second connection part detach. The first connection part and the second connection part respectively include a first connection surface and a second connection surface that are arranged opposite to each other. The first connection surface and the second connection surface are both provided with a first magnetic part and a second magnetic part that attract each other and can be spontaneously adsorbed when the two are close. There is a movable buckle that can slide on the first connection surface, and there is a corresponding limiting groove on the second connection surface. When the first connection surface and the second connection surface are mutually adsorbed and fitted, the movable buckle can slide into the limiting groove and limit the relative movement of the first connection part and the second connection part in a direction perpendicular to the first connection surface and the second connection surface, so as to prevent the two from being separated and fixed. When it is necessary to remove, the two can be separated by only needing the movable buckle to escape from the limiting groove. This structure enables the assembly to be spontaneously aligned and moved to a certain extent through the magnetic part, making it more convenient to assemble and disassemble.

[0012] Preferably, the driving member comprises a third magnetic member, and the third magnetic member can drive the movable buckle to slide into the limiting groove under the action of the second magnetic member.

[0013] In this solution, with the above structure, the movement of the movable buckle is also achieved by magnetic components, enabling it to be driven by the second magnetic component during the assembly process. In this way, during assembly, while the first connecting portion and the second connecting portion are attracted to each other under the action of the first magnetic component and the second magnetic component, and while achieving self-alignment and adsorption, the movable buckle can move into the limiting groove under the interaction of the third magnetic component and the second magnetic component to complete the fixation. The entire process is completely spontaneous. The user only needs to bring the first connecting portion and the second connecting portion close to each other during assembly to quickly and accurately complete the connection and assembly, greatly improving the convenience of operation and the assembly efficiency.

[0014] Preferably, the first connecting portion includes a first protruding portion protruding from the first connecting surface. A receiving groove is provided in the first protruding portion. The movable buckle is arranged in the receiving groove and can slide in the extending direction of the receiving groove. The third magnetic component is arranged on the movable buckle.

[0015] The second connecting portion includes a second protruding portion protruding from the second connecting surface. The limiting groove is arranged in the second protruding portion. The second magnetic component is arranged in the second protruding portion.

[0016] The first magnetic component is arranged at a position on the first connecting surface corresponding to the second protruding portion.

[0017] In this solution, with the above structure, by adopting this structure with both ends protruding and staggered, it can shorten the distances between the second magnetic component and the first magnetic component and the third magnetic component, improving the effect of their magnetic interaction. At the same time, it can pull the first magnetic component and the second magnetic component apart, reducing the unnecessary interaction between the two and enhancing the connection effect.

[0018] Preferably, a recessed portion is formed by inward depression on the surface of the first connecting portion. The first magnetic component is arranged in the recessed portion. The second protruding portion can partially extend into the recessed portion.

[0019] In this solution, with the above structure, by providing a recessed portion on the surface of the first connecting portion, it can further improve the effect of the magnetic interaction between the first magnetic component and the second magnetic component and between the third magnetic component and the second magnetic component, and reduce the effect of the interaction between the first magnetic component and the third magnetic component. Moreover, through this interlocking and staggered effect, it can also enhance the connection stability between the first connecting portion and the second connecting portion.

[0020] Preferably, it further includes a rotating seat. One end of the first connecting portion is rotatably connected to the rotating seat. The first connecting portion can rotate and fit or separate from the second connecting portion.

[0021] In this solution, the above structure is adopted. By setting the rotating seat, installation can be achieved only by rotating the first connecting part by different angles during assembly and disassembly, which is more convenient.

[0022] Preferably, the first magnetic member is arranged at one end of the first connecting part away from the rotating seat.

[0023] In this solution, the above structure is adopted. The magnetic member is arranged at one end away from the rotating seat. Using the torque principle, the connection strength is higher. In addition, being arranged at a position away from the rotation center can make the distance between the two magnetic members change most significantly with the rotation angle. Only by rotating a small angle can the magnetic force of the magnetic member change significantly, which is convenient for installation and disassembly.

[0024] Preferably, the first connecting part further includes a push switch, the push switch is connected to the movable buckle, and the movable buckle can be driven by the push switch to slide.

[0025] In this solution, the above structure is adopted. By setting the push switch, the movable buckle can be conveniently operated, which is convenient for installation and disassembly.

[0026] Preferably, the first connecting part further has a positioning connecting piece, and the second connecting part is provided with a positioning and cooperating piece corresponding to the positioning connecting piece. When the first connecting surface and the second connecting surface are fitted and connected, the positioning connecting piece and the positioning and cooperating piece cooperate with each other to limit the relative movement of the first connecting part and the second connecting part in the movement direction of the movable buckle.

[0027] In this solution, the above structure is adopted. The positioning connecting piece can further prevent the relative movement of the first connecting part and the second connecting part in the movement direction of the movable buckle, avoid the relative movement of the two causing them to separate from each other, and improve the connection stability.

[0028] Preferably, the first magnetic member and / or the second magnetic member is a neodymium iron boron magnet.

[0029] An all-inclusive bulletproof helmet, characterized in that it includes a helmet, a face mask and the connecting structure as described above. The first connecting part of the connecting structure is fixed to the face mask, the second connecting part of the connecting structure is fixed to the helmet, and the helmet and the face mask are assembled through the connecting structure.

[0030] In this solution, the above structure is adopted, and this kind of helmet and face shield are connected by a connecting structure. The helmet is fixed to the second connecting part, and the face shield is fixed to the first connecting part. The soldier can hold the first connecting part with one hand and bring it close to the corresponding first connecting part. Under the action of magnetic attraction, the first connecting part and the second connecting part will automatically fit together to complete the assembly, greatly reducing the operations and time required for assembly and disassembly, enabling the soldier to disassemble and install the bulletproof face shield with one hand, providing the soldier with more movement possibilities, which is particularly important and can protect the soldier's safety at critical moments.

[0031] Preferably, the lower rear edge of the helmet extends downward and bulges on both sides to form ear protection parts;

[0032] Both sides of the face shield have convex surfaces corresponding to the ear protection parts;

[0033] The first connecting part is fixed to the convex surface, and the second connecting part is fixed to the ear protection part. When the first connecting part is connected to the second connecting part, the convex surface and the ear protection part fit and close.

[0034] Preferably, it further includes goggles. The upper side shape of the goggles corresponds to the lower front edge of the helmet, and the lower side shape of the goggles corresponds to the upper edge of the face shield. The goggles are arranged between the face shield and the helmet and completely enclose the gap between the face shield and the helmet.

[0035] In this solution, the above structure is adopted, and the helmet body is generally in the shape of a hemispherical shell structure. When in use, it is worn on the head and mainly plays a protective role for the upper and rear parts of the head. The face shield structure is generally in the shape of a quarter spherical shell, mainly protecting the nasal bone to the lower jaw and the bilateral mandible bones of the face. The bulletproof mirror fills the uncovered area of the face and mainly protects the eyes and the surrounding area, wrapping the head, eyes, and face in all directions to prevent non-directional injuries caused by explosion fragments on the battlefield.

[0036] Preferably, a cuttlefish bone bracket is arranged on the helmet, and the helmet is connected to the goggles through a cantilever connecting rod.

[0037] In this solution, the above structure is adopted. Through the cantilever connecting rod and the cuttlefish bone bracket, the flexibility and mobility of the goggles can be ensured, and while the disassembly is convenient, the connection strength is improved.

[0038] The positive and progressive effects of the present invention are as follows: This solution discloses a connection structure and a fully enclosed bulletproof helmet. The connection structure includes a first connection part and a second connection part that can be disassembled from each other. The first connection part and the second connection part can be respectively fixed to two components that need to be connected. The two components that need to be connected are assembled together through the cooperation of the first connection part and the second connection part. When disassembly is required, only the connection structure needs to be operated to separate the first connection part and the second connection part. The first connection part and the second connection part respectively include a first connection surface and a second connection surface that are oppositely arranged. The first connection surface and the second connection surface are both provided with a first magnetic part and a second magnetic part that attract each other and can spontaneously adsorb when approaching. The first connection surface has a movable buckle that can slide, and the second connection surface has a corresponding limit groove. When the first connection surface and the second connection surface adsorb and fit with each other, the movable buckle can slide into the limit groove and restrict the relative movement of the first connection part and the second connection part from the direction perpendicular to the first connection surface and the second connection surface, preventing the two from separating and completing the fixation. When disassembly is required, only the movable buckle needs to be disengaged from the limit groove to separate the two. This structure enables the assembly to be self-aligning and movable to a certain extent through the magnetic parts, making its assembly and disassembly more convenient. Connecting the face mask and the helmet through this connection structure enables the soldier to disassemble and install the bulletproof face mask with one hand, providing more movement possibilities for the soldier, which is particularly important and can protect the soldier's safety at critical moments.

[0082] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the described embodiments for this reason.

[0083] Embodiment 1

[0084] As Figure 1 、 2 shown, this embodiment provides a full - coverage bulletproof helmet 2, which includes a helmet 2, a face shield 3, a connection structure 1 for detachably connecting between the helmet 2 and the face shield 3, and goggles 4. This helmet 2 and face shield 3 are connected through a special connection structure 1 provided by the present invention. This connection structure 1 can significantly reduce the operations and time required for assembly and disassembly, enabling soldiers to disassemble and install the bulletproof face shield 3 with one hand, providing soldiers with more movement possibilities and protecting soldiers' safety at critical moments.

[0085] As Figures 3 to 9 shown, the connection structure 1 of this embodiment includes a first connection part 11 and a second connection part 12 on the helmet 2 and the face shield 3 respectively. Among them, the first connection part 11 includes a first magnetic member 118 provided on a first connection surface 110 of the first connection part 11 and a movable buckle 115 that can slide back and forth in a straight - line direction parallel to the plane where the first connection surface 110 is located under the action of a driving member. The second connection part 12 includes a second magnetic member 124 provided on a second connection surface 120 of the second connection part 12 and a limiting groove 122. The first connection surface 110 and the second connection surface 120 are oppositely arranged and can be adsorbed and attached under the action of the first magnetic member 118 and the second magnetic member 124. When the first connection surface 110 and the second connection surface 120 are attached and connected, the limiting groove 122 is located on the sliding path of the movable buckle 115, and the movable buckle 115 can slide into the limiting groove 122 and be limited in the direction perpendicular to the first connection surface 110.

[0086] The connecting structure 1 includes a first connecting portion 11 and a second connecting portion 12 that can be disassembled from each other. The first connecting portion 11 and the second connecting portion 12 can be respectively fixed to two components to be connected. In this embodiment, the first connecting portion 11 is fixed to the face mask 3, and the second connecting portion 12 is fixed to the helmet 2. The helmet 2 and the face mask 3 are assembled through the connecting structure 1. The two components to be connected are assembled together through the cooperation of the first connecting portion 11 and the second connecting portion 12. When disassembly is required, only the connecting structure 1 needs to be operated to separate the first connecting portion 11 and the second connecting portion 12. The first connecting portion 11 and the second connecting portion 12 respectively include a first connecting surface 110 and a second connecting surface 120 that are oppositely arranged. The first connecting surface 110 and the second connecting surface 120 are both provided with a first magnetic member 118 and a second magnetic member 124 that attract each other, and can be spontaneously adsorbed when approaching under the action of the two. The first connecting surface 110 has a movable buckle 115 that can slide, and the second connecting surface 120 has a corresponding limiting groove 122. When the first connecting surface 110 and the second connecting surface 120 are adsorbed and attached to each other, the movable buckle 115 can slide into the limiting groove 122 and restrict the relative movement of the first connecting portion 11 and the second connecting portion 12 from the direction perpendicular to the first connecting surface 110 and the second connecting surface 120, preventing the two from separating and completing the fixation. When disassembly is required, only the movable buckle 115 needs to be disengaged from the limiting groove 122 to separate the two. This structure enables the assembly to be self-aligned and moved to a certain extent through the magnetic members, making both its assembly and disassembly more convenient.

[0087] As Figure 7 shown, the driving member includes a third magnetic member 1151. The third magnetic member 1151 can drive the movable buckle 115 to slide into the limiting groove 122 under the action of the second magnetic member 124. The movement of the movable buckle 115 is also realized through the magnetic member, enabling it to be driven to move by the second magnetic member 124 during the assembly process. Thus, during assembly, while the first connecting portion 11 and the second connecting portion 12 attract each other under the action of the first magnetic member 118 and the second magnetic member 124, and complete self-alignment and adsorption, the movable buckle 115 can move into the limiting groove 122 under the interaction of the third magnetic member 1151 and the second magnetic member 124 to complete the fixation. The entire process is completely spontaneous. The user only needs to bring the first connecting portion 11 and the second connecting portion 12 close to each other when assembly is required to quickly and accurately complete the connection and assembly, greatly improving the convenience of operation and the assembly efficiency.

[0088] When conducting long-term combat operations, due to the relatively large weight of the helmet 2, it will cause great fatigue to the soldiers. At this time, the function of quickly disassembling and installing the face mask 3 with one hand will be particularly prominent. When a soldier encounters an emergency, he needs to hold a gun in one hand and wear the face mask 3 in the other hand. Under the action of the connecting structure 1, the soldier can hold the single-sided first connecting part 11 with one hand and horizontally move it close to the corresponding second connecting part 12 on the single side. Under the action of the magnetic attraction force, the second connecting part 12 on the single side will automatically fit with the first connecting part 11. At the same time, the movable buckle 115 in the first connecting part 11 is embedded into the limiting groove 122 of the second connecting part 12 under the action of the third magnetic part 1151, entering the locked state.

[0089] The first magnetic part 118, the second magnetic part 124 and the third magnetic part 1151 are all strong magnets, preferably neodymium iron boron magnets, so that on the one hand, they can meet the function of automatic positioning and installation, and on the other hand, they can ensure the connection strength.

[0090] In this embodiment, as Figure 5 shown, the third magnetic part 1151 of the movable buckle 115 is a small magnet, which is arranged inside the movable buckle 115 and can be attracted by the second magnetic part 124 on the second connecting part 12, so that when the first connecting part 11 and the second connecting part 12 approach each other as Figure 4 , Figure 7 when, under the action of the magnetic force, the whole movable buckle 115 is driven to approach the second magnetic part 124 and the movable buckle 115 is snapped into the limiting groove 122, as Figure 8 shown.

[0091] In other embodiments, the third magnetic part 1151 can also be set to be in a repulsive relationship with the second magnetic part 124. At this time, the second magnetic part 124 needs to be arranged in the direction of the movable buckle 115 away from the limiting groove 122. When the first connecting part 11 and the second connecting part 12 approach, the movable buckle 115 is pushed to move away from the second magnetic part 124 by the repulsive force and enters the limiting groove 122.

[0092] In addition, in other embodiments, the magnet of the driving part can also be replaced with other structures, such as replaced with a spring, or an electric movable structure, etc., and other methods are used instead of magnetic force to realize the movement of the movable buckle 115.

[0093] When a soldier is aiming in combat with the cheek against the stock, the face needs to be close to the sight for aiming, and the face mask 3 will affect the aiming line of sight. Under the action of the connection structure 1, the disassembly process of the bulletproof face mask 3 can be completed with one hand. First, press the push switch 112 of the first connection part 11 on one side of the helmet body. The movable buckle 115 inside the first connection part 11 will disengage from the limit groove 122 of the second connection part 12. At this time, the locking state between the first connection part 11 and the matching second connection part 12 on this side begins to be released, and the connection structure 1 on one side of the bulletproof face mask 3 is opened, and the bulletproof face mask 3 enters the single-side buckle suspension state. Then press the push switch 112 on the other side of the bulletproof face mask 3. At this time, the locking state between the first connection part 11 and the second connection part 12 on this side begins to be released. At this time, the connection structures 1 on both sides of the bulletproof face mask 3 are all released, so as to further achieve the purpose of quickly removing the bulletproof face mask 3 with one hand. If both hands act on the push switches 112 on both sides at the same time, the purpose of quickly removing with both hands can be achieved, greatly reducing the combat load. While effectively protecting the soldier's head from being hit by flying bullets and shrapnel, it also ensures the combat efficiency of the soldier. In this way, the working principle of the device is completed.

[0094] As Figures 5 to 8 shown, the first connection part 11 includes a first protrusion 111 protruding from the first connection surface 110. An accommodation groove 114 is provided inside the first protrusion 111. The movable buckle 115 is arranged in the accommodation groove 114 and can slide in the extending direction of the accommodation groove 114. The third magnetic part 1151 is arranged on the movable buckle 115. The second connection part 12 includes a second protrusion 121 protruding from the second connection surface 120. The limit groove 122 is arranged inside the second protrusion 121. The second magnetic part 124 is arranged inside the second protrusion 121. The first magnetic part 118 is arranged at the position of the first connection surface 110 corresponding to the second protrusion 121.

[0095] In this embodiment, when the first protrusion 111 and the second protrusion 121 are assembled, they are in an interlaced connection and cooperation state. The openings of the accommodation groove 114 and the limit groove 122 are arranged opposite to each other. When the movable buckle 115 extends out of the accommodation groove 114, it can be snapped into the limit groove 122.

[0096] Adopting this structure with protrusions at both ends and interlacing can make the distances between the second magnetic part 124 and the first magnetic part 118 and the third magnetic part 1151 all shorter to improve the effect of their magnetic interaction. At the same time, the first magnetic part 118 and the second magnetic part 124 are pulled apart to reduce the unnecessary interaction between the two and improve the connection effect.

[0097] In another embodiment, the positions of the first protrusion 111 and the second protrusion 121 can also be changed to a certain extent. For example, the limiting groove 122 can be arranged at the edge of the side surface of the second connecting portion 12, and the movable buckle 115 of the first connecting portion 11 can protrude from the edge of the first connecting portion 11 and be inserted into the limiting groove 122 on the side surface of the second connecting portion 12 for fixation. Or the relationship between the first connecting portion 11 and the second connecting portion 12 and the limiting groove 122 of the movable buckle 115 can be swapped, etc. As long as it can be ensured that after connection, the two can be limited in the direction in which they can be separated from each other (i.e., the direction in which the first connecting surface 110 and the second connecting surface 120 are perpendicular) to prevent them from separating.

[0098] As Figure 5 shown, a recess 116 is formed by inward depression on the surface of the first connecting portion 11. The first magnetic member 118 is arranged in the recess 116, and the second protrusion 121 can partially extend into the recess 116. In this embodiment, a part of the receiving groove 114 is also in the recess 116, which is convenient for the second protrusion 121 to extend into the recess 116 during assembly for alignment and cooperation.

[0099] By providing the recess 116 on the surface of the first connecting portion 11, the magnetic effect of the first magnetic member 118 and the second magnetic member 124 and the third magnetic member 1151 and the second magnetic member 124 can be further enhanced, and the effect of the first magnetic member 118 and the third magnetic member 1151 can be reduced. Moreover, through this interlocking effect of mutual nesting, the connection stability between the first connecting portion 11 and the second connecting portion 12 can also be improved.

[0100] The first magnetic member 118 is arranged in the recess 116, and the second magnetic member 124 is arranged in the second protrusion 121. When the second protrusion 121 extends into the recess 116, the first magnetic member 118 and the second magnetic member 124 are closest and have the strongest suction force.

[0101] As Figures 5 to 8As shown in the figure, the second connecting portion 12 is also provided with a positioning connecting member, and the first connecting portion 11 is provided with a positioning fitting corresponding to the positioning connecting member. When the first connecting surface 110 and the second connecting surface 120 are fitted and connected, the positioning connecting member and the positioning fitting cooperate with each other and restrict the relative movement of the first connecting portion 11 and the second connecting portion 12 in the movement direction of the movable buckle 115. In this embodiment, the positioning fitting is a horizontal groove structure provided inside the recess 116, and the positioning connecting member is a tongue-like structure extending horizontally at the outer end of the second protrusion 121. When the first connecting portion 11 and the second connecting portion 12 are assembled, the second protrusion 121 extends into the recess 116, and the movable buckle 115 is clamped in the limiting groove 122 to limit the first connecting portion 11 and the second connecting portion 12 in the horizontal direction, while the tongue-like structure of the positioning connecting member is clamped in the groove structure of the positioning fitting to limit the first connecting portion 11 and the second connecting portion 12 in the vertical direction.

[0102] The positioning connecting member can further prevent the relative movement of the first connecting portion 11 and the second connecting portion 12 in the movement direction of the movable buckle 115, avoid the relative movement of the two causing them to separate from each other, and improve the connection stability.

[0103] As Figure 3 shown in the figure, it further includes a rotating seat 13. One end of the first connecting portion 11 is rotatably connected to the rotating seat 13, and the first connecting portion 11 can rotate and fit or separate from the second connecting portion 12. By providing the rotating seat 13, during assembly and disassembly, only by rotating the first connecting portion 11 by different angles can the installation be realized, which is more convenient.

[0104] Two rotating seats 13 are respectively embedded with two mounting holes 131. The two mounting holes 131 are in parallel relative positions. Both ends of the stainless steel optical axis 132 are respectively embedded in the two mounting holes 131. Two parallel through holes 113 are provided at the bottom of the first connecting portion 11 to penetrate the stainless steel optical axis 132 therein, and both ends are fixed to the inside of the mounting holes 131, thereby constituting a rotating mechanism between the first connecting portion 11 and the rotating seat 13, and realizing the single-handed wearing and disassembly actions of the face mask 3.

[0105] In this embodiment, the same connecting structure 1 is provided on both sides of the face mask 3 and the helmet 2, which enables the full-face bulletproof helmet 2 to provide a semi-connected single-sided suspension wearing strategy. During the above equipment operation, only the connecting structure 1 on one side is disassembled and assembled, that is, only the connecting structure 1 on one side is fixed. Due to the rotational connection relationship between the first connecting portion 11 and the rotating seat 13, the face mask 3 can be in a single-sided suspension state, and this state can cooperate with operations such as aiming with the gun against the cheek, external device communication, eating and drinking, etc., so as to better adapt to the changing combat environment on the battlefield.

[0106] The connecting structure 1 includes a fixed seat 14 and a rotating seat 13. On one side of the fixed seat 14, a limiting structure 141 and two fixing holes 142 for screw installation are provided. The rotating seat 13 extends outwardly and protrudes, and two horizontal fixing holes 142 are provided on the upper side. The lower surfaces of the fixed seat 14 and the rotating seat 13 are respectively in curved surface contact with the helmet body and the face mask 3, and a tight structure is formed by means of connecting screws. The connecting screws between the fixed seat 14 and the helmet body are arranged longitudinally, and the connecting screws between the rotating seat 13 and the bulletproof face mask 3 are arranged horizontally. At the same time, in order to adapt to the central position of the face mask 3 and the angle during suspension, the screw connection line has a certain angle with the horizontal and vertical directions. A stainless steel shaft is embedded in the rotating seat 13 and connected to the first connecting portion 11 to form a rotating structure.

[0107] As Figure 7 , Figure 8 shown, the first magnetic member 118 is provided at one end of the first connecting portion 11 away from the rotating seat 13. By setting the magnetic member at one end away from the rotating seat 13 and using the torque principle, the connection strength is higher. In addition, setting it at a position away from the rotation center can make the distance between the two magnetic members change most significantly with the rotation angle, and only a small rotation angle is required to significantly change the magnetic force of the magnetic member, which is convenient for installation and disassembly.

[0108] As Figures 6 to 9 shown, the first connecting portion 11 further includes a push switch 112. The push switch 112 is connected to the movable buckle 115, and the movable buckle 115 can be driven and slide by the push switch 112. As Figure 9 shown, in this embodiment, the push switch 112 and the movable buckle 115 are integrally provided. The bottom of the movable buckle 115 has a connecting structure 1 connecting the push switch 112, and the push switch 112 is arranged at the top of the first connecting portion 11 for convenient operation. By setting the push switch 112, the movable buckle 115 can be conveniently operated, which is convenient for installation and disassembly.

[0109] As Figure 1 , Figure 2 shown, the lower rear edge of the helmet 2 extends downward and protrudes on both sides to form ear protection parts 21. Both sides of the face mask 3 have convex surfaces 31 corresponding to the ear protection parts 21. The first connecting portion 11 is fixed to the convex surface 31, and the second connecting portion 12 is fixed to the ear protection parts 21. When the first connecting portion 11 and the second connecting portion 12 are connected, the convex surface 31 and the ear protection parts 21 are attached and closed.

[0110] The lower rear edge of the helmet 2 body extends longitudinally to obtain a larger rear neck protection area; the ear protection areas on both sides of the helmet body are provided with larger convex surfaces 31 outward, having a larger ear protection area and being more suitable for wearing combat tools inside the helmet body.

[0111] The appearance of the bulletproof face shield 3 adopts the same material and curved surface form as the helmet body to improve the bulletproof level of the face shield 3 and the coordination between the bulletproof face shield 3 and the helmet body. In addition, combined with the characteristics of the human face, it not only increases the overall protection area of the face shield 3, but also sets protrusions and convex surfaces on the front and both sides of the face shield 3 to focus on strengthening the protection of the cheeks and the bridge of the nose. In addition, the bulletproof face shield 3 is thinned relative to the helmet body of the helmet 2 for easy wearing.

[0112] The second connecting part 12 is connected to the helmet 2 through the fixing seat 14, and the side of the fixing seat 14 facing the helmet 2 has a curved surface structure corresponding to the surface shape of the helmet 2.

[0113] Such as Figure 1 、 Figure 2 As shown, it also includes a goggle 4. The upper side shape of the goggle 4 corresponds to the lower edge of the front side of the helmet 2, and the lower side shape of the goggle 4 corresponds to the upper edge of the face shield 3. The goggle 4 is arranged between the face shield 3 and the helmet 2 and completely closes the gap between the face shield 3 and the helmet 2.

[0114] The helmet body is generally in the shape of a hemispherical shell. When in use, it is worn on the head and mainly plays a protective role for the upper and rear parts of the head. The structure of the face shield 3 is generally in the shape of a quarter spherical shell, mainly protecting the nasal bone of the face to the lower jaw and the bilateral lower jaw bones. The bulletproof mirror fills the uncovered area of the face and mainly protects the eyes and the surrounding area, wrapping the head, eyes and face in all directions to prevent undirected damage caused by explosion fragments on the battlefield.

[0115] Such as Figure 1 、 Figure 2 As shown, a squid bracket 22 is provided on the helmet 2, and the helmet 2 is connected to the goggle 4 through a cantilever connecting rod 41. Through the cantilever connecting rod 41 and the squid bracket 22, the flexibility and mobility of the goggle 4 can be ensured, and while being convenient to disassemble, the connection strength is improved. The helmet 2 is the core of the full - enclosed bulletproof helmet 2. The goggle 4 is fixed on the squid bracket 22 through the cantilever connecting rod 41, and the squid bracket 22 is fixed on the helmet body by screws. The face shield 3 is detachably connected to the connecting structure 1 and the helmet body through the rotating seats 13 on both sides.

[0116] The full - enclosed bulletproof helmet 2 of the present invention has the following effects:

[0117] (1) The design of the full - enclosed bulletproof helmet 2 realizes large - area protection of the head, wraps the head, eyes and face in all directions, and prevents undirected damage caused by explosion fragments on the battlefield. At the same time, this quick - release full - enclosed bulletproof helmet 2 is designed starting from the helmet body, continuing the material of the helmet body and optimizing the structural characteristics, and optimizing the design of the helmet 2, face shield 3 and goggle 4, giving visual consistency while ensuring the use performance.

[0118] (2) For traditional fully enclosed bulletproof helmets 2, most of them adopt a rail-type dismountable bulletproof face shield 3. When in use, both hands are required to simultaneously find the accurate positions of the bilateral rails and push them in at the same time to complete the installation of the bulletproof face shield 3. The operation is difficult and the operation efficiency is low. In order to improve the operation efficiency of the bulletproof helmet 2 among different wearing requirements, a quick disassembly and assembly function design is added to the bulletproof face shield 3 part of the above-mentioned quick-release fully enclosed bulletproof helmet 2. The specific operation is as follows: Hold the first connecting part 11 of the face shield 3 with the thumbs and middle fingers of both hands. When assembling, find the corresponding position of the second connecting part 12 with both hands. Under the action of a strong magnet, a locking structure is automatically formed with the first connecting part 11, and the tongue-shaped structure of the pressing switch 112 on the first connecting part 11 will lift, indicating that the first connecting part 11 is in a locked state, and the installation operation is completed; when disassembling, keep the positions of both hands unchanged, press the tongue-shaped structure of the pressing switch 112 of the first connecting part 11 with the index finger, and at the same time, turn the first connecting part 11 to both sides with the thumb and middle finger to quickly remove the face shield 3 and complete the disassembly operation.

[0119] (3) The existing bulletproof face shield 3 has a single wearing state, only having two states of synchronous locking on both sides and synchronous separation on both sides. For individual combat, there are many inconveniences. Considering the different wearing requirements of soldiers on the battlefield, the above-mentioned quick-release fully enclosed bulletproof helmet 2 provides a semi-connected single-sided suspension wearing strategy. In the above equipment operation, only the disassembly and assembly operation of one side connecting mechanism is performed, that is, only one side connecting mechanism is fixed. Due to the rotation structure of the first connecting part 11 and the rotating seat 13, the face shield 3 can achieve a single-sided suspension state, and this state can cooperate with operations such as holding a gun against the cheek for aiming, external device communication, eating and drinking, etc., so as to better adapt to the changing combat environment on the battlefield.

[0120] (4) The existing fully enclosed bulletproof helmet 2 has the problem that the disassembly and assembly process of the bulletproof face shield 3 can only be completed by synchronous operation of both hands. For individual combat personnel, the above problems greatly occupy the use space of both hands. Through the optimized quick-release component, soldiers can perform single-handed disassembly and assembly operations on the bulletproof face shield 3, so as to adapt to the complex combat environment. Referring to the above assembly operation, individual combat personnel can choose to first fix one side connecting structure 1 with one hand to form the above single-sided suspension state, and then install the other side connecting structure 1 to complete the bilateral installation; when disassembling, unlock the connecting structure 1 on the opposite side with one hand to form a single-sided suspension state, and then unlock the connecting structure 1 on the same side to complete the bilateral disassembly. Single-handed disassembly and assembly can maximize the operation ability of soldiers on the battlefield and provide more action possibilities for soldiers, which is particularly important and can protect the safety of soldiers at critical moments.

[0121] Example 2

[0122] Such as Figure 10 、 Figure 11As shown, the structure of this embodiment is generally the same as that of Embodiment 1. The difference is that in this embodiment, the driving part realizes the sliding of the movable buckle 115 through a spring. In this embodiment, a spring is set as the power source of the movable buckle 115, and the elastic force of the spring supports the movable buckle 115 to extend. When assembly is required, the movable buckle 115 is pressed down by pressing the switch 112 for assembly or disassembly.

[0123] The driving part can be provided with only a spring without the third magnetic part 1151. In this case, manual operation of pressing the switch 112 is required both during assembly and disassembly, which is rather inconvenient.

[0124] The driving part can also be provided with both a spring and the third magnetic part 1151. The spring can assist the movable buckle 115 to extend or keep the movable buckle 115 in the receiving groove 114 during assembly, thus facilitating disassembly and assembly.

[0125] It should be noted that this connection structure provided by the present invention can be used not only for the connection between a helmet and a face mask, but also for other devices such as backpack hanging parts as a connection structure to achieve the corresponding quick-release effect.

[0126] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are all based on the orientation or positional relationship shown during the normal use process of the device or component, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0127] Although the specific embodiments of the present invention have been described above, those skilled in the art should understand that this is only an example, and the protection scope of the present invention is defined by the appended claims. Without departing from the principle and essence of the present invention, those skilled in the art can make various changes or modifications to these embodiments, but these changes and modifications all fall within the protection scope of the present invention.
