Description

Technical Field

[0001] The utility model belongs to the technical field of protective equipment, and in particular relates to a photoelectric autonomous counter-attack shield. Background Art

[0002] In various sudden attacks, police officers, soldiers and security personnel are actually in an extremely dangerous environment. In most cases, users can only use shields to block attacks, split and disperse the crowd or form a defense line and divert the crowd in mass incidents. They have been in a very passive state. In past mass incidents, the soldiers had a hard time coping because they were too passive. Some of them were even attacked before they could react. In attacks on security personnel, it is usually sudden and personnel cannot react. Conventional shields only serve as barriers and are overly dependent on personnel operation, so the effect is poor.

[0003] According to the feedback from frontline personnel, especially in mass incidents, the crowd has already begun to attack and destroy the shield wall before the protective formation is formed, which seriously threatens the life, health and safety of frontline users. With the progress of society and the upgrading of weapons and equipment, the existing shields are no longer able to fully cope with today's emergency situations.

[0004] No active self-defense shields have been found so far. Dispersion shields at home and abroad only require active operation by users, mainly based on sound wave dispersal and strong light dispersal. There are some electromagnetic riot shields on the Internet, but they all require full operation by users and have little practical significance.

[0005] The existing shields have the following problems in responding to mass emergencies and being deployed to the front line of the public security and armed police: there is a certain window period, such as when shouting is ineffective, and then actively activated, the reaction speed is too slow, and it is unable to respond to emergencies; when facing mass incidents, the effect is not strong, and the crowd cannot be effectively dispersed, and the protection ability is no different from that of ordinary shields, and even due to weight and other reasons, the protection effect on officers and soldiers is even worse. When subduing extremists, the shield still needs to be withdrawn to a certain extent, resulting in a defense gap. During this stage, extremists are very likely to pick up weapons again to attack law enforcement officers. This process is extremely dangerous and extremely unfavorable to the capture of extremists. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technical methods, the purpose of the utility model is to provide a photoelectric autonomous counter-attack shield that can perform autonomous protection, avoid protection gaps, and improve the protection effect.

[0007] To achieve the above purpose, the utility model adopts the following technical solution: a photoelectric autonomous counter-attack shield, comprising:

[0008] A shield body, wherein an observation window is provided on the shield body;

[0009] The electric shock piece group is arranged on the outside of the shield body, and the discharge piece is placed in the middle and is electrically connected to the central controller;

[0010] The ultrasonic sensor is arranged on the outside of the shield body, placed in the middle of the shield below the observation window, and electrically connected to the central controller;

[0011] A strong light group is arranged on the outside of the shield body, the strong light group is placed above the observation window, and is electrically connected to the central controller;

[0012] A central controller is arranged inside the shield body;

[0013] A hand-held component, arranged inside the shield body;

[0014] and a battery, embedded inside the shield body to power the device;

[0015] The electric shock sheet group includes a plurality of electric shock sheets, and the electric shock sheet includes a discharge pile and a rubber base, the rubber base is fixed on the outer surface of the shield body, the discharge pile is fixed on the rubber base, the wire of the discharge pile is connected to the high voltage side of the high-low voltage DC transformer, the storage battery is connected to the low voltage side of the high-low voltage DC transformer, and the electric energy of the storage battery is increased to high voltage by the high-low voltage DC transformer to supply power to the electric shock sheet;

[0016] The ultrasonic sensor transmits ultrasonic waves and receives ultrasonic echoes, converts them into corresponding electrical signals, and transmits them to the central controller. After receiving the signals, the central controller starts the strong light group and the electric shock piece group.

[0017] Furthermore, the shield body adopts a sandwich structure, including an outer steel structure layer, an intermediate circuit integration layer and an inner layer.

[0018] Furthermore, a circuit board is arranged in the intermediate circuit integration layer, and a buffer protection layer is arranged around the circuit board.

[0019] Furthermore, the buffer protection layer is made of sponge-like plastic.

[0020] Furthermore, the strong light set adopts multiple high-power LED lamp beads.

[0021] Furthermore, the storage battery is a lithium battery.

[0022] The beneficial effects of adopting this technical solution are:

[0023] The dispersing self-defense integrated shield designed by the utility model fully considers that the emergency personnel cannot react in the first time due to the sudden occurrence of the incident, and cannot protect themselves well and maintain the current state. In order to ensure that a certain gap can be created for the user to react in the first time, the subjugation of extremists, and the protection of front-line officers and soldiers, etc., it is different from other dispersing shields that must be actively started and operated, and cannot meet the needs of the armed police force in the front line of emergency. In particular, in terms of detection and response, the ultrasonic range measurement is used to automatically start the electric shock system and the strong light dizziness system when the impact crowd is detected, and the officers and soldiers can be protected by themselves. Its electronic pulse device can not only protect the user, but also paralyze the extremists, and it can be safer and more convenient to subdue the extremists, and it can effectively protect the officers and soldiers. In the non-contact period, due to the large discharge sound and sound and light effects during the pulse discharge process, it has a strong deterrent effect on extremists, which can leave a better and larger gap for the user, and can better respond to behaviors and measures.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described below with reference to the accompanying drawings.

[0030] In this embodiment, see Figure 1-Figure 3 As shown, an optoelectronic autonomous counter-attack shield comprises:

[0031] A shield body 1, on which an observation window 2 is arranged;

[0032] The electric shock piece group 3 is arranged outside the shield body 1 and is electrically connected to the central controller 6;

[0033] The ultrasonic sensor 4 is arranged outside the shield body 1 and is electrically connected to the central controller 6;

[0034] A strong light group 5 is arranged outside the shield body 1 and is electrically connected to the central controller 6;

[0035] A central controller 6 is arranged inside the shield body 1;

[0036] A hand-held component 7, arranged inside the shield body 1;

[0037] and a storage battery 8, embedded inside the shield body 1 to supply power to the device;

[0038] The electric shock sheet group 3 includes a plurality of electric shock sheets, and the electric shock sheet includes a discharge pile 31 and a rubber base 32. The rubber base 32 is fixed on the outer surface of the shield body 1, and the discharge pile 31 is fixed on the rubber base 32. The wire of the discharge pile 31 is connected to the high voltage side of the high-low voltage DC transformer 9, and the battery 8 is connected to the low voltage side of the high-low voltage DC transformer 9. The electric energy of the battery 8 is increased to high voltage by the high-low voltage DC transformer 9 to supply power to the electric shock sheet. Under the power supply of a small power source, the DC transformer can emit a very high voltage, and under the control of the single-chip microcomputer, it is equipped with a voltage regulation function. In the activated state, it discharges to paralyze or stun the person who touches it, which has a greater deterrent effect on the person who impacts it, is cheap, and the device is simple and reliable.

[0039] The ultrasonic sensor 4 transmits ultrasonic waves and receives ultrasonic echoes, converts them into corresponding electrical signals, and transmits them to the central controller 6. After receiving the signals, the central controller 6 starts the strong light group 5 and the electric shock piece group 3.

[0040] The ultrasonic sensor 4 is placed in the middle of the shield below the observation window 2, so as to facilitate the detection of the target. The strong light group 5 is placed above the observation window 2, so as to facilitate the illumination of the target person's eyes to block his vision. The discharge plate is placed in the middle, so as to facilitate the electric shock to the target. The shield adopts a multi-grip design. Considering the pressure of holding it for a long time on one hand, the double-grip design makes it convenient to hold the shield for a long time. Since the shield itself has an attack effect, the baton can be omitted. When necessary, the shield can be directly used to hit the opponent to cause electric shock damage.

[0041] As an optimization solution of the above embodiment, Figure 4 As shown, the shield body 1 adopts a sandwich structure, including an outer steel structure layer 11 , an intermediate circuit integration layer 12 and an inner layer 13 .

[0042] The outermost layer is a normal steel shield, but its thickness is relatively thinner than that of a normal steel shield. Only the edge area is the same thickness as a normal steel shield, which makes it convenient to deal with sharp weapons.

[0043] A circuit board is arranged in the middle circuit integration layer 12 , and a buffer protection layer is arranged around the circuit board.

[0044] The main goal of the buffer protection layer is to protect the circuit and the innermost facilities, and it can also slightly reduce the impact effect. Different from the existing electric shock shields on the market, which are very easy to damage the circuit and various electronic components after being attacked, the integrated circuit is wrapped with a movable but not easy to bend buffer protection layer of plastic. When the outermost layer is damaged, the connection of the structure can be strengthened to prevent it from being fragmented. While increasing the difficulty of breaking the shield, it also has better protection for the circuit. When the outer structure of the shield is damaged, the existing circuit and related electrical components can be directly disassembled and reassembled by directly replacing the outer structure, which enhances economic benefits. Unlike existing shields, most of them cannot be repaired and reused after being damaged, which is a serious waste.

[0045] Preferably, the buffer protection layer is made of sponge-like plastic.

[0046] It can provide effective cushioning, and it is interwoven with integrated circuit mesh and some plastic threads, which can strengthen the structure. When it is broken, it will not fall off immediately, but will have a certain connection and still have a certain protective effect.

[0047] The innermost layer is made of soft plastic, which is convenient for processing, easy to produce and easy to install internal components.

[0048] As an optimization solution of the above embodiment, the strong light group 5 uses multiple high-power LED lamp beads.

[0049] It makes fast-approaching extremists dizzy for a short period of time under strong light and unable to see the target clearly. After activation, it instantly gives the approaching extremists high-intensity radiation, making it impossible for them to visually lock onto the target and psychologically fearful. The power supply of this system is shared with the electric shock system.

[0050] As an optimization solution of the above embodiment, the storage battery 8 adopts a lithium battery. The battery has the advantages of high energy density and long service life. Since the lithium battery has a high rated voltage, this feature is particularly suitable for the shield that adopts pulse discharge as the discharge method. In addition, the lithium battery has a high power tolerance and can withstand a long period of discharge. The lithium battery is also easy to store and has a relatively low self-discharge rate, which is convenient for daily maintenance and combat readiness requirements.

[0051] Select the mode you want to activate before use. According to test results, the strong light stun system can stun people within five meters for 1.5-3 seconds. According to existing reports, if a person is exposed to strong light while rushing in a certain direction, it will strongly interfere with his sense of direction and produce a subconscious fear. This can reduce the impact on the shield wall when resisting extremists. The high-voltage discharge system is referenced by experimental data of the same discharge method and voltage. In the case of overpressure discharge, it can cause shock and convulsions in the human body. Under the regulation of appropriate voltage, it can make the human body in a state of muscle paralysis, which is convenient for capture and containment during action. The detection system uses ultrasonic waves to detect the enemy. After testing, it can accurately capture fast-approaching objects within five meters and respond within 0.2 seconds.

[0052] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
