Description

Technical Field

[0001] The utility model relates to the technical field of safety protection equipment, in particular to a dynamic adjustment protection structure of a bulletproof vest. Background Art

[0002] Tactical body armor is a type of protective equipment specially designed to provide protection and enhance combat effectiveness. It is usually made of bulletproof materials (such as Kevlar, ceramic plates, etc.) and can effectively resist bullets, shrapnel and other attacks, absorb and disperse the energy of bullets, thereby reducing damage to the body.

[0003] Existing tactical body armor generally utilizes a static protective structure, with the protective layer and liner fixedly connected, making it impossible to dynamically adjust the protection level according to different situations. When a user experiences a mild impact, the heavy protective structure is excessively heavy and reduces flexibility, hindering operation. Conversely, when facing high-impact attacks, the static protective structure's protective capabilities are insufficient, making it difficult to provide adequate protection and meet the requirements of different protection levels. Furthermore, the protective performance cannot be adjusted in real time as the environment changes. Consequently, existing body armor has limitations in practical applications and cannot fully meet the user's safety and protection needs. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a dynamic adjustment protection structure for bulletproof vests.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A dynamically adjustable protective structure for a bulletproof vest comprises a main body of the bulletproof vest, wherein an inner protective layer is provided on the outer wall of the main body of the bulletproof vest, an outer protective layer is provided on the outer surface of the inner protective layer, and a gradient structure is formed from the outside to the inside between the outer protective layer, the inner protective layer, and the main body of the bulletproof vest, and a connecting belt is fixedly connected to the outer wall of the outer protective layer, and a plurality of storage pockets are provided on the connecting belt;

[0007] A gas storage tank is provided in one of the storage bags, a micro electric pump is provided at the bottom of the gas storage tank, a ventilation tube is provided at the output end of the micro electric pump, an inflatable airbag is fitted on the inner side of the bulletproof vest body, an inflation port is provided on one side of the bottom of the inflatable airbag, and one end of the ventilation tube extends into the inflation port and is connected to the inflatable airbag.

[0008] Preferably, a shape memory gold layer is laminated between the body of the bulletproof vest and the inflatable airbag, a pressure sensor is laminated on the outer wall of the shape memory gold layer, and a microcontroller is laminated on the inner wall of the shape memory gold layer.

[0009] Preferably, a strain sensor is provided on the inner wall of the inflatable airbag, and the strain sensor and the pressure sensor are both electrically connected to the microcontroller.

[0010] Preferably, a release valve is provided on one side of the ventilation tube close to the micro electric pump, the micro electric pump and the release valve are electrically connected to the micro controller, and adjustable shoulder straps are symmetrically provided on both sides of the top of the body of the bulletproof vest.

[0011] Preferably, the body of the bulletproof vest is made of PE non-woven fabric, the inner protective layer is made of high-performance fiber composite material, and the outer protective layer is made of textile composite material.

[0012] The beneficial effects of the utility model are:

[0013] The dynamic adjustment of the shape memory gold layer and inflatable bladder improves the protective effectiveness of the body armor, enhancing its comfort and versatility. When at rest, the shape memory gold layer and inflatable bladder remain soft, not hindering the tactical personnel's movements. Upon impact with a bullet, the shape memory gold layer rapidly hardens, enhancing localized impact resistance. Simultaneously, a pressure sensor detects external force and, through a microcontroller, activates a micro-electric pump and release valve to release gas, rapidly filling the inflatable bladder. This increases the vest's energy absorption pathways and reduces the impact energy transmitted to the wearer, acting as a "cushion." The inflatable bladder also adjusts to the tactical personnel's body shape, ensuring effective protection for individuals of varying body types, enhancing its dynamic adjustment.

[0022] Example:

[0023] Reference Figure 1-3 A dynamically adjustable protective structure for a bulletproof vest includes a body of the bulletproof vest 1. An inner protective layer 2 is disposed on the outer wall of the body of the bulletproof vest 1. An outer protective layer 3 is disposed outside the inner protective layer 2. A gradient structure is formed from the outside to the inside between the outer protective layer 3, the inner protective layer 2, and the body of the bulletproof vest 1. A connecting belt 4 is fixedly connected to the outer wall of the outer protective layer 3. A plurality of storage bags 5 are disposed on the connecting belt 4.

[0024] A gas storage tank 6 is provided in one of the storage bags 5, a micro electric pump 7 is provided at the bottom of the gas storage tank 6, a ventilation tube 8 is provided at the output end of the micro electric pump 7, an inflatable airbag 9 is fitted on the inner side of the bulletproof vest body 1, an inflation port 10 is provided on one side of the bottom of the inflatable airbag 9, and one end of the ventilation tube 8 extends into the inflation port 10 and is connected to the inflatable airbag 9.

[0025] A shape memory gold layer 11 is laminated between the body of the bulletproof vest 1 and the inflatable airbag 9 . A pressure sensor 12 is laminated on the outer wall of the shape memory gold layer 11 . A microcontroller 13 is disposed on the inner wall of the shape memory gold layer 11 .

[0026] A strain sensor 14 is provided on the inner wall of the inflatable airbag 9 . The strain sensor 14 and the pressure sensor 12 are both electrically connected to the microcontroller 13 .

[0027] A release valve 15 is provided on one side of the ventilation tube 8 close to the micro electric pump 7 . The micro electric pump 7 , the release valve 15 and the micro controller 13 are electrically connected. Adjustable shoulder straps 16 are symmetrically provided on both sides of the top of the body of the bulletproof vest 1 .

[0028] The body of the bulletproof vest 1 is made of PE non-woven fabric, the inner protective layer 2 is made of high-performance fiber composite material, and the outer protective layer 3 is made of textile composite material.

[0029] In this embodiment, when a tactical personnel needs to wear the body armor 1, they first insert the body armor 1 so that it fits the wearer's body. The adjustable shoulder straps 16 are then used to adjust the size of the body armor 1, allowing the body armor 1 to fit the wearer's body shape. When the tactical personnel is struck by a bullet, the outer protective layer 3 disperses the initial impact energy of the bullet and provides a certain degree of wear resistance, while the inner protective layer 2 prevents the bullet from penetrating. When the body armor 1 is struck by a bullet, the body armor 1 senses external pressure and transmits it to the shape memory gold layer 11. The shape memory gold layer 11 senses the external force and undergoes a phase change, thereby changing its shape and stiffness. In its normal state, the shape memory gold layer 11 is relatively soft and does not hinder the tactical personnel's mobility. However, when the bullet strikes, the shape memory gold layer 11 rapidly hardens, increasing the local impact resistance, thereby achieving dynamic performance adjustment.

[0030] Specifically, when the body of the bulletproof vest 1 is subjected to external pressure impact, the pressure sensor 12 detects the presence of a specific external force, and then the pressure sensor 12 transmits a signal to the microcontroller 13. Subsequently, the microcontroller 13 immediately sends a signal and starts the micro electric pump 7 and the release valve 15 in sequence, thereby quickly releasing the gas inside the gas storage tank 6, so that the gas passes through the vent pipe 8 and inflates the inflatable airbag 9 through the inflation port 10, so that the inflatable airbag 9 expands rapidly, increasing the energy absorption path of the body of the bulletproof vest 1, thereby reducing the impact energy transmitted to the human body and reducing To prevent harm to the human body, when the inflatable airbag 9 is being inflated, the deformation of the surface of the inflatable airbag 9 can be measured in real time by the strain sensor 14, thereby further improving the overall protective effect of the body of the bulletproof vest 1. At the same time, when the inflatable airbag 9 is being inflated, the tactical personnel can dynamically adjust the expansion degree of the inflatable airbag 9 in real time according to their own needs and situations. For thinner people, the inflation volume can be appropriately reduced to make the body of the bulletproof vest 1 more fitting. For people with a fuller figure, the inflation volume can be increased. While ensuring the protection area, the comfort and versatility are improved, thereby enhancing its dynamic adjustment protection effect.
