Description

Technical Field

[0001] The present invention relates to the technical field of bulletproof equipment, and in particular to a rapidly deployable foldable bulletproof shield and a working method thereof. Background Art

[0002] The bulletproof shield is an important piece of protective equipment for individual soldiers or small groups, widely used in military, police, security and other scenarios. Its core function is to protect users from damage caused by high-speed impact objects such as bullets and fragments, providing a safe shelter so that users can safely perform tasks or protect personnel in dangerous environments.

[0003] Prior art discloses a foldable integrated protective shield, comprised of multiple protective panels spliced together, with adjacent panels folding together via hinges or other connectors. To compensate for potential weaknesses in protection at the folded joints (i.e., the seams between adjacent panels), which create protective gaps when deployed, additional protective plates are typically installed behind the seams for reinforcement. This structure enhances the protective capabilities of the seam area to a certain extent. However, this shield presents the following issues: First, due to the gaps between adjacent protective panels and the difficulty of the reinforced protective panels to completely and tightly cover all folding angle areas, the shield has weak protection points when unfolded, especially at the corner positions, resulting in insufficient protection reliability and safety hazards.

[0004] Secondly, the fixed structure of the reinforced protective plate set up to fill the gap will hinder the complete folding and fitting of the panel, resulting in the overall volume (thickness) of the folded shield still being large, failing to fully utilize the advantages of the folding design to maximize storage space savings.

[0005] In addition, the presence of reinforced protective plates increases the complexity of the folding structure, making the folding and unfolding operations less flexible and smooth, affecting the speed of shield deployment. Summary of the Invention

[0016] An embodiment of the present invention further provides a method for operating the rapidly deployable foldable bulletproof shield as described above, comprising: When the foldable panel is switched from the stowed state to the unfolded state, the foldable panel unfolds in response to the movement of the support frame, and the first rotating rod and the second rotating rod of the stabilizing assembly maintain the unfolded state of the foldable panel; the first bullet-proof glass is rotated upward relative to the foldable panel, and then the second bullet-proof glass is rotated outward relative to the first bullet-proof glass, and the second bullet-proof glass and the foldable panel are plugged and connected, so that the observation mechanism and the foldable panel have the same shape; When switching from the expanded state to the retracted state, the multiple layers of support rods are staggered and folded to form multiple folded surfaces of the bulletproof panel and put it in the retracted state; the plug-in connection between the second bulletproof glass and the foldable panel is released, the second bulletproof glass is rotated inward relative to the first bulletproof glass, and then the first bulletproof glass is rotated downward relative to the foldable panel to achieve the retraction of the observation mechanism.

[0017] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages: 1. The bulletproof shield of the present invention comprises a bulletproof panel, a support frame, and a stabilizing assembly. The bulletproof panel incorporates a bulletproof layer within the internal gaps of the foldable panel, integrating bulletproof and folding functions. The support frame's multiple layers of parallel support rods are connected by a pivoting connecting rod, allowing adjacent support rods to fold back and forth in an interlaced manner when stowed, forming a compact folding surface. The first and second rotating rods of the stabilizing assembly are respectively fixed to adjacent folding surfaces, and their rotational damping provides both deployment angle limiting and posture maintenance.

[0018] 2. The first bulletproof glass of the present invention is rotatably connected and foldable, which greatly reduces the overall volume of the shield and facilitates carrying and transportation. The combination of the first bulletproof glass and the second bulletproof glass greatly increases the observation field of view, allowing the user to have a more comprehensive understanding of the external situation. The matching structure of the positioning pin and the positioning hole is simple and effective, which can accurately fix the position of the second bulletproof glass to ensure that it will not shake during the observation process, thereby ensuring the stability and accuracy of the observation.

[0019] Additional advantages of the present invention will be given in the description which follows, and in part will be obvious from the description which follows, or may be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

Unless otherwise specified, all technical and scientific terms used herein have the same meanings as commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0022] Example 1 like Figure 1 、 Figure 2 As shown, this embodiment provides a foldable bulletproof shield that can be quickly deployed, including: a bulletproof panel, a support frame and a stabilizing component; Figure 4 As shown, the bulletproof panel includes a foldable panel 1 and a bulletproof layer 3. There is a gap inside the foldable panel 1, and the bulletproof layer 3 is arranged in the gap; the support frame is also installed in the gap, as shown in FIG. Figure 3 As shown, it includes support rods 4 and connecting rods 5, the support rods 4 have multiple layers, and each layer of support rods 4 are arranged in parallel, the two ends of the connecting rods 5 are respectively rotatably connected to the two adjacent layers of support rods 4, and the two adjacent layers of support rods 4 are staggered and folded front and back when stored, so that the bullet-proof panel forms multiple folding surfaces; the stabilizing component includes a first rotating rod 7 and a second rotating rod 8, the first rotating rod 7 and the second rotating rod 8 are respectively fixed on the adjacent folding surfaces, and the two rotating rods are rotatably connected and have set damping.

[0023] The integral foldable panel 1 and the bulletproof layer 3 are both equipped with support frames and stabilizing components to avoid the existence of weak points in protection. The foldable design can save space when idle, making transportation and storage convenient. The foldable panel 1 with bulletproof effect can be quickly unfolded and remain stable when in use, ensuring reliability during use. The bulletproof layer 3 composed of multiple internal buffer layers can effectively absorb and disperse bullet energy to achieve excellent bulletproof function. The overall design enables it to be quickly unfolded at the required position, providing timely, reliable and comprehensive bulletproof protection for personnel and equipment, and improving safety and emergency response capabilities.

[0024] The bulletproof layer 3 of this embodiment is composed of a laminate of ultra-high molecular weight polyethylene fiber non-woven fabrics with a surface density of 18 kg / m 2 It is measured that the structure with this surface density can block the impact of 7.62×39mm ordinary bullets, reaching the GA423-2015 level 5 bulletproof standard.

[0025] Each layer of support rods 4 has three, with the side support rods 4 positioned at an obtuse angle to the center support rod 4. These support rods 4 give the foldable panel 1 a trapezoidal, semi-enclosed cross-section. This layout enhances the foldable panel's structural strength. When subjected to external impact, the trapezoidal, semi-enclosed structure effectively disperses force. Multiple support rods 4 transmit and disperse force from different angles, enhancing the shield's overall stability and reliability. When impacted by high-speed impact objects like bullets, the impact force is more effectively transmitted to the entire panel, preventing damage from excessive localized force and better ensuring user safety.

[0026] The bulletproof shield further includes an observation mechanism 2 , which is located on the upper side of the bulletproof panel and includes a first bulletproof glass 201 and two second bulletproof glasses 202 . The two second bulletproof glasses 202 are located on both sides of the first bulletproof glass 201 and have the same shape as the support rod 4 .

[0027] The setting of the observation mechanism 2 expands the user's observation field of view. The combination of the first bulletproof glass 201 and the second bulletproof glass 202 allows the user to have a more comprehensive understanding of the external situation, facilitates positioning and observation, and at the same time has the same shape as the support rod 4, ensuring the consistency and coordination of the overall appearance of the shield without affecting the protective performance and structural integrity of the shield.

[0028] like Figure 6 As shown, the trapezoidal semi-enclosed foldable panel 1 includes a middle panel structure and inclined panel structures on both sides. The first bulletproof glass 201 is rotatably connected to the middle panel structure along a first rotation axis, and the second bulletproof glass 202 is rotatably connected to the first bulletproof glass 201 along a second rotation axis with set damping. The second bulletproof glass 202 can be plugged into the inclined panel structure, wherein the first rotation axis is parallel to the middle support rod 4, and the second rotation axis is perpendicular to the first rotation axis.

[0029] The first rotating axis is parallel to the middle support rod 4, ensuring that the rotation plane is consistent with the main plane of the shield. The second rotating axis is perpendicular to the first rotating axis, so that the second bulletproof glass 202 can be flipped outward to a tilted panel structure; it is easy to operate during the unfolding and storage process, and cooperates with the folding and unfolding actions of the entire shield to ensure that the observation mechanism 2 is close to the shield when stored, reducing the space occupied, and can be quickly put into use when unfolded, thereby improving the practicality and convenience of the shield.

[0030] The second bullet-proof glass 202 is provided with a slot 203 perpendicular to the first rotating shaft, and the top of the inclined panel structure is provided with a positioning hole 205. A positioning pin 204 is inserted into the slot 203 of the second bullet-proof glass 202 and the positioning hole 205 of the inclined panel structure to achieve a plug-in connection, effectively fixing the position of the second bullet-proof glass 202, preventing shaking during observation that affects the stability and accuracy of observation, ensuring that the user can observe the external situation clearly and stably, and at the same time facilitating installation and disassembly, and can be quickly fixed or released during storage and deployment, thereby enhancing the overall performance and user experience of the shield.

[0031] like Figure 6As shown, the rear side of the foldable panel 1 is provided with a lifting handle 9, and the outer wall of the lifting handle 9 is provided with an anti-slip cover 11, and the anti-slip cover 11 has anti-slip grooves 12. The design of the lifting handle 9 facilitates the user's operation when unfolding or folding the foldable panel 1, improving the convenience of use, especially in emergency situations, allowing for quick access or operation of the shield. The provision of the anti-slip cover 11 and anti-slip grooves 12 increases the friction when the user grasps the lifting handle 9, effectively preventing hand slippage, ensuring safe and accurate operation, and allowing the user to stably control the shield in dangerous environments without affecting its normal protective function.

[0032] like Figure 2 As shown, the lifting handle 9 is located at the upper portion of the rear side of the foldable panel 1. A buckle 14 is provided on the lifting handle 9. An insert block 13 is provided at the lower portion of the rear side of the foldable panel 1. When the foldable panel 1 is folded, the insert block 13 is inserted into the buckle 14. This design can secure the shield when folded and stored, preventing accidental unfolding and ensuring regular storage. Combined with the folding structure of the shield, it improves the fixing method in the folded state, ensuring that the shield maintains a good storage shape when not in use, and is convenient for access at any time.

[0033] For details, please refer to the attached Figure 1 -Attached Figure 4 The bulletproof shield includes a foldable panel 1, which serves the purpose of structural reinforcement and can maintain the flatness of the bulletproof layer surface when the shield is unfolded. A flexible bulletproof layer 3 is fixedly installed inside the foldable panel 1. The bulletproof layer 3 is composed of multiple buffer layers and can withstand the impact of bullets. It is lightweight, effectively reducing the overall weight while ensuring ballistic performance. Multiple support rods 4 are fixedly connected to the upper and lower sides of the inner wall of the bulletproof layer 3 to enhance structural stability. The rear ends of the adjacent support rods 4 are rotatably connected to connecting rods 5. The support rods 4 and connecting rods 5 are rotatably connected and have strong rigidity, so they can support the foldable panel 1 and bulletproof layer 3.

[0034] The rear side of the foldable panel 1 is rotatably connected to a plurality of first rotating rods 7, the bottom ends of which are each rotatably connected to a second rotating rod 8. The plurality of first rotating rods 7 and the second rotating rod 8 are rotatably connected and have a certain degree of damping, allowing the foldable panel 1 to be smoothly unfolded and folded. The bottom ends of the plurality of second rotating rods 8 are rotatably connected to the foldable panel 1. When the foldable panel 1 is unfolded, the first rotating rods 7 and the second rotating rods 8 rotate around the connection point. The connection between the first rotating rods 7 and the second rotating rods 8 prevents excessive rotation between the support rods 4 and the connecting rod 5, maintaining the stability of the entire shield. The first rotating rods 7 and the second rotating rods 8 limit the maximum rotation angle of the support rods 4 and the connecting rod 5, allowing for quick response during unfolding and folding.

[0035] The diameters of the multiple support rods 4 are equal to the diameters of the multiple connecting rods 5, which ensures coordination and stability during the support and rotation process, making the structure more balanced. The lengths of the multiple first rotating rods 7 are equal to the lengths of the multiple second rotating rods 8, ensuring that the movement amplitude and force on both sides of the foldable panel 1 are consistent when unfolding and folding, which is conducive to maintaining overall stability.

[0036] A lifting handle 9 is provided on the rear side of the foldable panel 1. The lifting handle 9 is convenient for the user to operate when unfolding or folding the foldable panel 1, thereby improving the convenience of use. A plurality of first screws 10 are threadedly connected to the front side of the outer wall of the lifting handle 9. The lifting handle 9 is threadedly connected to the foldable panel 1 through the first screws 10, thereby enhancing the connection stability of the lifting handle 9. Anti-slip sleeves 11 are fixedly connected to the left and right sides of the outer wall of the lifting handle 9. The outer walls of the two anti-slip sleeves 11 are provided with anti-slip grooves 12. The anti-slip sleeves 11 increase the friction when the user holds the lifting handle 9, thereby avoiding hand slippage and ensuring the safety and accuracy of the operation.

[0037] In the initial state, the foldable panel 1 is in a folded storage state (eg Figure 7 As shown), to save space and facilitate transportation and storage, when the bulletproof shield is needed, the foldable panel 1 is unfolded. Since the foldable panel 1 is made of soft material, it can maintain a certain shape and structural stability during the unfolding process under the action of the support rod 4, the connecting rod 5, the first rotating rod 7 and the second rotating rod 8. The internal bulletproof layer 3 is composed of multiple buffer layers. When a bullet hits, the buffer layer can effectively absorb and disperse the energy of the bullet, thereby achieving a bulletproof function. The multiple support rods 4 provide support for the foldable panel 1 and the bulletproof layer 3, enhancing the overall structural strength. The first rotating rod 7 and the second rotating rod 8 enable the foldable panel 1 to move flexibly during the unfolding and folding process, and can maintain a stable shape and angle after unfolding. Through this design, the bulletproof shield can be quickly and effectively deployed at the required position to provide reliable bulletproof protection; Please see the attached Figure 2 -Attached Figure 6 The top of the foldable panel 1 is provided with an observation mechanism 2, which is used to provide observation protection, allowing the user to observe external conditions from inside. The observation mechanism 2 includes a first bulletproof glass 201, which is rotatably connected (e.g., via a hinge structure) to the top center of the foldable panel 1, allowing it to be folded for easy carrying. Second bulletproof glass 202 is rotatably connected to the left and right sides of the outer wall of the first bulletproof glass 201. The top of each second bulletproof glass 202 has a slot 203, and the inner walls of each slot 203 are slidably connected to a positioning pin 204. Positioning holes 205 are provided on the left and right sides of the top of the foldable panel 1. Both positioning pins 204 penetrate the second bulletproof glass 202 and engage with the positioning holes 205.

[0038] The first bulletproof glass 201 and the second bulletproof glass 202 increase the field of view of observation. When the position of the second bulletproof glass 202 needs to be fixed, the two positioning pins 204 slide on the inner wall of the corresponding slot 203. The positioning pins 204 penetrate the second bulletproof glass 202 and engage with the positioning holes 205 opened on the left and right sides of the top of the foldable panel 1, thereby fixing the second bulletproof glass 202 in the desired position and ensuring the stability and accuracy of observation. When storing, first remove the positioning pin 204 on the right side, rotate the second bulletproof glass 202 on the right side to the rear side of the first bulletproof glass 201, and then remove the positioning pin 204 on the left side. Since the second bulletproof glass 202 on the left side is misaligned with the second bulletproof glass 202 on the right side, the second bulletproof glass 202 on the left side can be rotated to the rear side of the second bulletproof glass 202 on the right side, realizing the folding function.

[0039] Please see the attached Figure 2 -Attached Figure 5 The bottom of the rear side of the outer wall of the foldable panel 1 is fixedly connected with an insert block 13, and the middle part of the outer wall of the lifting handle 9 is fixedly connected with a buckle 14. The buckle 14 is engaged with the insert block 13, which plays a fixing role when folding and storing. When the foldable panel 1 is folded, the lifting handle 9 can be fixed in a suitable position to prevent it from shaking at will and ensure the regularity of storage; The left side of the rear end of the outer wall of the foldable panel 1 is fixedly connected to the installation box 15, and the inner wall of the installation box 15 is fixedly connected to the positioner 16, which can obtain the position information of the bulletproof shield in real time for easy monitoring and management; the right side of the bottom of the inner wall of the foldable panel 1 is provided with an information board 6 (such as Figure 5 As shown, the information plate 6 is used to mark the parameters of the shield. Second screws 17 are threadedly connected to the four corners of the information plate 6. The information plate 6 is threadedly connected to the foldable panel 1 through the second screws 17 to prevent the information plate 6 from falling.

[0040] Working principle: Before using the shield, the foldable panel 1 is in a folded and stored state to save space and facilitate transportation and storage. When the bulletproof shield is needed, the foldable panel 1 is unfolded and can maintain a certain shape and structural stability during the unfolding process. The internal bulletproof layer 3 is composed of multiple layers of buffer layers. When a bullet hits, the buffer layer can effectively absorb and disperse the energy of the bullet, thereby achieving a bulletproof function. Multiple support rods 4 provide support for the foldable panel 1 and the bulletproof layer 3, enhancing the overall structural strength. The first rotating rod 7 and the second rotating rod 8 enable the foldable panel 1 to move flexibly during the unfolding and folding process, and maintain a stable shape and angle after unfolding. Through this design, the bulletproof shield can be quickly and effectively deployed at the required position to provide reliable bulletproof protection.

[0041] The first bulletproof glass 201 is rotatably connected to the middle part of the top of the foldable panel 1, so that it can be folded and easy to carry. The first bulletproof glass 201 and the second bulletproof glass 202 increase the field of view of observation. When the position of the second bulletproof glass 202 needs to be fixed, the two positioning pins 204 slide on the inner walls of the corresponding slots 203. The positioning pins 204 pass through the second bulletproof glass 202 and engage with the positioning holes 205 opened on the left and right sides of the top of the foldable panel 1, thereby fixing the second bulletproof glass 202 in the desired position, ensuring the stability and accuracy of observation, so that police officers can observe within a safe range.

[0042] Example 2 This embodiment provides a method for operating a rapidly deployable foldable bulletproof shield as described in Example 1: When switching from the stored state to the unfolded state, the foldable panel 1 unfolds in response to the action of the support frame, and the first rotating rod 7 and the second rotating rod 8 of the stabilizing component maintain the unfolded state of the foldable panel 1; the first bulletproof glass 201 is rotated upward relative to the foldable panel 1, and then the second bulletproof glass 202 is rotated outward relative to the first bulletproof glass 201, and the second bulletproof glass 202 and the foldable panel 1 are plugged and connected, so that the observation mechanism 2 and the foldable panel 1 have the same shape, and can be quickly put into use to play the protection and observation functions.

[0043] Deployment phase: The support frame drives the panel to unfold, the damping lever maintains the position, the first bullet-resistant glass 201 is rotated first, and the second bullet-resistant glass 202 is deployed, and then the latch is locked. The support frame is deployed first to provide a stable base for the glass components; the glass rotates from the inside out to avoid mechanical interference; the latch is finally locked to ensure precise alignment.

[0044] When switching from the unfolded state to the retracted state, the multi-layer support rods 4 are staggered and folded to form multiple folded surfaces of the bulletproof panel and are in the retracted state; the plug connection between the second bulletproof glass 202 and the foldable panel 1 is released, the second bulletproof glass 202 is rotated inward relative to the first bulletproof glass 201, and then the first bulletproof glass 201 is rotated downward relative to the foldable panel 1, so that the observation mechanism 2 is retracted (such as Figure 7 shown).

[0045] Storage stage: Release the latch → fold the second glass inward → flip the first glass down → fold the support rods 4 in an interlaced manner. Release the latch first to prevent the glass from being damaged by stress. Finally, fold the support rods 4 to allow gravity to self-align. The entire process requires no tools, allowing for quick and convenient storage.

[0046] The actions of various components coordinate with each other throughout the entire process, ensuring the convenience and reliability of the shield when unfolding and folding, and ensuring that the user can complete the switching of the shield status in a short time. Whether it is quickly deploying protection in response to emergencies or folding it for easy carrying and storage, it reflects the shield's efficient and flexible working characteristics and fully demonstrates its performance advantages of rapid deployment and foldability.

[0047] Although the above describes the specific embodiments of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
