Description

Technical Field

[0001] This utility model relates to the field of police equipment technology, and in particular to a multifunctional integrated protective police arm shield. Background Technology

[0002] Arm shields are a commonly used police tool when police officers are on duty. They can be used for both offense and defense, protecting police officers as well as attacking criminals.

[0003] In law enforcement activities, officers often face various dangerous situations, but traditional police arm shields have limited functionality, typically offering only basic protection. Faced with complex and ever-changing law enforcement environments, such as terrorist attacks and emergencies, existing arm shields cannot meet officers' needs in terms of protection, warning, emergency window breaking, and portability. For example, traditional arm shields use only a single layer of rigid material, lacking an effective cushioning mechanism. If struck by heavy objects such as batons or stones, the impact will be directly applied to the officer's arm without any buffering, easily leading to serious injuries such as arm fractures and contusions, failing to adequately protect officer safety. In nighttime law enforcement scenarios, the lack of effective warning and lighting devices hinders officers' ability to perform their duties and ensure their own safety. When urgently entering enclosed spaces, the lack of window-breaking tools delays rescue opportunities. Furthermore, during long patrols or operations, an arm shield that is not easily portable increases the burden on officers and affects operational efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multifunctional integrated protective police arm shield.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multifunctional integrated protective police arm shield includes a PC board, with anti-slash strips fixedly connected to the periphery of the PC board. A buffer layer is provided at the bottom of the PC board, and a honeycomb layer is fixedly connected to the outer wall of the buffer layer. The honeycomb layer is composed of several honeycomb-shaped hexagonal unit structures. A damping layer is fixedly connected to the outer wall of the honeycomb layer, and a pressure sensor is provided on the outer wall of the damping layer. The output end of the pressure sensor abuts against the outer wall of the PC board.

[0007] Preferably, a warning light plastic shell is fixedly connected to one side of the bottom of the PC board, a warning light switch is provided on one side of the outer wall of the warning light plastic shell, a controller is provided inside the warning light plastic shell, the warning light switch is electrically connected to the input terminal of the controller through a connecting wire, two warning flashing lights are provided on the outer wall of the PC board, and the output terminal of the controller is connected to the warning flashing lights and electrically connected to the warning flashing lights.

[0008] Preferably, the bottom of the buffer layer is provided with an installation groove, and two sets of installation posts are provided in the installation groove. One set of installation posts is fixedly connected to a handle base at its end. A folding handle is provided on one side of the handle base via a pivot. A rectangular groove is provided on one side of the handle base, and an unlocking key is connected in the rectangular groove via a compression spring. An adjustment webbing is fixedly connected to the end of the other set of installation posts.

[0009] Preferably, both the buffer layer and the honeycomb layer have slots on their sides, and the slots and the bottom of the PC board form a storage slot for placing a baton. The two ends of the storage slot are fixedly connected with clamps.

[0010] Preferably, the PC board and the buffer layer board have a fixing groove on their sides, and a window breaker head is fixedly connected in the fixing groove by a cap nut.

[0011] Preferably, the buffer layer is filled with buffer sponge, and the damping layer is filled with damping material.

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

[0013] This arm shield employs a multi-layered composite protective structure. When impacted, pressure sensors monitor the impact force in real time, and damping layers adaptively adjust their damping characteristics based on the impact intensity. Under high-intensity impacts, energy is converted into heat through internal molecular friction and internal dissipation, delaying the transmission of force. The honeycomb layer utilizes a honeycomb structure to evenly disperse the impact force, preventing excessive local stress. The buffer layer's cushioning sponge absorbs the remaining impact force again, providing comprehensive and multi-layered effective protection for the officer's arm. This significantly enhances the arm shield's ability to protect officers in complex and dangerous scenarios, replacing the traditional single-protection structure of arm shields.

[0014] This arm shield, equipped with a flashing warning light, is suitable for nighttime law enforcement scenarios and can also serve as a deterrent and warning to criminals. When officers need to urgently enter enclosed spaces, the window-breaking head can quickly shatter glass obstacles, avoiding delays in rescue due to waiting for window-breaking tools or difficulties in breaking windows. By designing the handle as a foldable handle, the arm shield can be folded for easy carrying in a backpack, greatly reducing the burden on officers during long patrols or operations, making it more portable, and improving operational flexibility and efficiency.

[0015] This arm shield integrates multiple functions such as protection, warning lighting, emergency window breaking, and portable storage, allowing police officers to flexibly utilize its various functions during law enforcement according to different scenarios and task requirements. It eliminates the need to carry multiple separate pieces of equipment, achieving efficient synergy of functions, significantly improving the convenience of law enforcement and comprehensive response capabilities, and fully meeting the multi-functional needs of police arm shields in complex and ever-changing law enforcement environments.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0024] Example:

[0025] Reference Figure 1-3 A multifunctional integrated protective police arm shield includes a PC board 1, with anti-slash strips 2 fixedly connected around the perimeter of the PC board 1, a buffer layer 3 at the bottom of the PC board 1, a honeycomb layer 4 fixedly connected to the outer wall of the buffer layer 3, the honeycomb layer 4 being composed of several honeycomb hexagonal unit structures, a damping layer 5 fixedly connected to the outer wall of the honeycomb layer 4, and a pressure sensor 6 installed on the outer wall of the damping layer 5, with the output end of the pressure sensor 6 abutting against the outer wall of the PC board 1.

[0026] A warning light plastic shell 7 is fixedly connected to one side of the bottom of the PC board 1. A warning light switch 8 is provided on one side of the outer wall of the warning light plastic shell 7. A controller is provided inside the warning light plastic shell 7. The warning light switch 8 is electrically connected to the input terminal of the controller through a connecting wire. Two warning flashing lights 9 are provided on the outer wall of the PC board 1. The output terminal of the controller is connected to the warning flashing lights 9 and is electrically connected to the warning flashing lights 9.

[0027] The bottom of the buffer layer 3 is provided with a mounting groove 10, and two sets of mounting posts 11 are provided in the mounting groove 10. One set of mounting posts 11 is fixedly connected to the end of a handle base 12. A folding handle 13 is provided on one side of the handle base 12 via a pivot. A rectangular groove is provided on one side of the handle base 12, and an unlocking button 14 is connected in the rectangular groove via a compression spring. The end of the other set of mounting posts 11 is fixedly connected to an adjusting webbing 15.

[0028] Both the buffer layer 3 and the honeycomb layer 4 have slots on their sides. The slots and the bottom of the PC board 1 form a storage slot 16 for placing a baton. The two ends of the storage slot 16 are fixedly connected with clamps 17.

[0029] The PC board 1 and the buffer layer board 3 have a fixing groove 18 on their sides, and a window break head 20 is fixedly connected in the fixing groove 18 by a cap nut 19.

[0030] The interior of the buffer layer 3 is filled with buffer sponge, and the interior of the damping layer 5 is filled with damping material.

[0031] In this implementation scheme, when an officer needs to use the arm shield for law enforcement duties, they first remove the baton from the clamp 17, then pass their arm through the adjusting webbing 15 and grasp the folding handle 13. Pulling the adjusting webbing 15 tightens it, ensuring the arm shield fits snugly against the arm. The officer can then hold the arm shield in one hand and the baton in the other for law enforcement duties. When the officer is struck by a heavy object while holding the arm shield, the PC board 1 receives the impact force and transmits it to the pressure sensor 6. The pressure sensor 6 detects the impact force parameters. Under low-intensity impacts, the damping material in the damping layer 5 maintains low damping, giving the arm shield a certain degree of flexibility for easy operation. Under high-intensity impacts, the impact energy is transmitted... Upon impact with the damping plate 5, the internal damping material deforms, generating friction and internal friction between its molecular chains or particles. Subsequently, the friction and internal friction generated by the damping material convert the impact energy into heat energy and dissipate some of the energy, slowing down the transmission speed of the impact force, thereby reducing the impact force transmitted to the officer's arm and reducing the damage to the officer's arm. When the PC plate 1 is impacted, its arm shield surface will vibrate. The resistance generated by the damping material inside the damping plate 5 during the vibration will hinder the vibration of the arm shield, causing the vibration to decay rapidly and consume the vibration energy, thereby preventing the arm shield from causing additional damage to the officer's arm due to continuous vibration. At the same time, it also helps the officer maintain a stable grip and control of the arm shield.

[0032] When the damping plate 5 reduces some of the impact force, when the impact force is transmitted to the honeycomb plate 4, the honeycomb structure of the honeycomb plate 4 can evenly distribute the impact force to each hexagonal unit, thereby avoiding the impact force being concentrated in a local area of ​​the PC plate 1, making the pressure on the entire arm shield more uniform. Subsequently, when the impact force is transmitted to the buffer plate 3 again, the buffer sponge inside the buffer plate 3 buffers and absorbs the impact force, thus forming a multi-layered protection for the officer's arm and improving the overall impact resistance of the arm shield.

[0033] Furthermore, when officers continuously use the arm shield, pressing the warning light switch 8 on one side transmits a signal to the controller. Upon receiving the signal, the controller activates the flashing lights 9, making it suitable for nighttime law enforcement scenarios. It also serves as a deterrent and warning to criminals. When officers need to urgently enter an enclosed space, the window breaker 20 on one side can quickly break glass obstacles, preventing delays in rescue due to waiting for window-breaking tools or difficulties in breaking windows. After completing the law enforcement task, officers can pull out their arm by loosening the adjustment strap 15, then rotate the folding handle 13 to fold it. Pressing the unlock button 14 will lock the handle 13 in place, preventing it from becoming loose during storage. This allows the arm shield to be folded and stored flat, making it easy to carry in a backpack and improving operational efficiency.
