Description

Technical Field

[0001] This invention relates to the field of riot control vehicle technology, specifically a police riot control command vehicle. Background Technology

[0002] Police riot control command vehicles are the mobile command centers for modern law enforcement agencies in handling major public safety crises. However, most of the command vehicles currently in service still have significant shortcomings in terms of practical application, survivability, and functional integration, which restricts their full effectiveness.

[0003] First, existing command vehicles severely lack proactive on-site response and self-protection capabilities. Most vehicles serve only as enclosed mobile command posts, their functions focused on information reception and command issuance. When a sudden attack occurs, the command vehicles themselves lack effective non-lethal proactive defense measures, often relying solely on external police forces for protection, making them highly vulnerable. Although a few models have attempted to be equipped with simple protective devices, they generally lack a physical interception system (such as riot nets) capable of rapid response, medium-to-long-range deployment, and reliable deployment, making the command frontline extremely vulnerable to direct attacks.

[0004] Secondly, existing vehicles have significant shortcomings in battlefield survivability and emergency mobility. Riot control environments are complex, and vehicle tires are easily punctured by obstacles, sharp objects, etc., causing the entire vehicle to instantly lose mobility and become a "sitting duck," posing a serious threat to command personnel and critical equipment inside. Traditional spare tire replacement methods are almost impossible to implement in dangerous environments, while ordinary solid run-flat tires, although they can maintain traction, severely sacrifice ride comfort and handling. Currently, there is a lack of an emergency mobility mechanism that can automatically and rapidly deploy after complete tire failure to ensure the safe evacuation of command vehicles even when damaged. Summary of the Invention

[0005] In response to the shortcomings of existing technologies, this invention provides a police riot control command vehicle that solves the problem that command vehicles themselves lack effective non-lethal active defense measures and often have to rely on external police forces for protection, making them extremely vulnerable to being caught off guard.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a police riot control command vehicle, comprising a vehicle chassis, a cargo box mounted on the vehicle chassis, and a command and communication system mounted within the cargo box, and further comprising:

[0007] An anti-riot net deployment device, integrated into the top of the compartment, is used to quickly launch and deploy the anti-riot net to the outside of the vehicle;

[0008] An emergency support wheel mechanism is mounted on the vehicle chassis and corresponds to the vehicle tires mounted on the side of the vehicle chassis, and is used to provide emergency support when the vehicle tires fail.

[0009] The recoil transfer structure connects the riot control net deployment device and the enclosure, and is used to transfer and offset part of the recoil force generated by the riot control net deployment device.

[0010] The riot control net deployment device includes a launch tube, a riot control net housed in the launch tube, and a drive mechanism that provides power for launching the riot control net. The launch tube is mounted on the top of the enclosure via a mounting base.

[0011] The driving mechanism is a compressed air driving mechanism, which includes a high-pressure gas cylinder fixedly installed at the tail of the launch tube. The tail of the launch tube is also provided with an explosion chamber. The high-pressure gas cylinder is connected to the explosion chamber in sequence through a pressure regulator and a solenoid valve.

[0012] The initial velocity of the riot control net The calculation formula is as follows:

[0013]

[0014] in, The initial velocity of the riot control net is given. The gas pressure inside the burst chamber. Let be the cross-sectional area of ​​the burst cavity. The length of the launch tube is [length]. The frictional force between the riot control net and the inner wall of the launch tube. The total mass of the riot control netting and its counterweights.

[0015] Preferably, the emergency support wheel mechanism includes a support wheel, a swing arm for retracting and extending the support wheel, and a drive component for driving the swing arm to move;

[0016] The support wheel, swing arm, and drive unit are housed in an internal cavity inside the vehicle chassis when not in operation. The drive unit is mounted on one side of the inner wall of the internal cavity. One end of the swing arm is connected to the drive unit, and the other end of the swing arm is connected to the support wheel.

[0017] The compartment includes a laterally expandable cabin, which is connected to the main compartment of the compartment via a translational expansion mechanism.

[0018] The translational expansion mechanism drives the expansion compartment to switch between a retracted state and an expanded state.

[0019] The translational extension mechanism includes a servo motor, which is installed inside the main cabin. The output end of the servo motor is fixedly connected to a lead screw, and the lead screw is threaded with a nut. The nut is connected to the extension compartment, which slides on the bottom wall of the main cabin, via an L-shaped rod.

[0020] Preferably, the diameter of the support wheel is smaller than the radius of the vehicle tire, and its receiving position is such that, in the lowered state, the bottom of the support wheel is lower than the lowest point of the tire profile after the vehicle tire fails.

[0021] Preferably, the edge of the riot control net is provided with a counterweight strip.

[0022] Preferably, the riot control net deployment device, emergency support wheel mechanism, recoil transfer structure, and translation extension mechanism are all electrically connected and centrally controlled by a command and communication system installed inside the compartment.

[0023] Preferably, the recoil force transfer structure includes a transfer seat, which is installed on the top of the body. The transfer seat has a magnetorheological damper inside and slides on both sides inside. A metal rod is installed inside one slide and a ceramic cylinder is installed inside the other slide. The outer wall of the ceramic cylinder is wound with resistance wire. The metal rod and the outer wall slide of the ceramic cylinder are connected by the same sliding plate. The mounting seat is fixed on the top of the sliding plate.

[0024] Preferably, both the metal rod and the outer wall of the ceramic cylinder are provided with terminals, which are electrically connected to the command and communication system via external lines.

[0025] Working Principle: This police riot control command vehicle serves as a highly integrated mobile command and response platform. Once the vehicle arrives at the mission site and comes to a stop, operators can issue an expansion command via the command and communication system to activate the translational expansion mechanism. A servo motor installed in the main compartment begins operation, driving a rigidly connected lead screw to rotate synchronously. The nut meshing with the lead screw moves axially under the drive of the thread, transmitting power to the expansion compartment via an L-shaped transmission rod, propelling it smoothly to the side along a pre-set rigid slide rail. This process expands the compact interior space of the vehicle, transforming it into a more spacious on-site command post, providing robust space support for subsequent long-duration, multi-person command and decision-making operations.

[0026] With the command center established, the vehicle's core operational functions immediately went into standby mode. Upon receiving the launch command, its riot net deployment system first adjusts the pressure of the compressed gas from the high-pressure cylinder using a digital pressure regulator, based on the target distance and environmental factors, to match the required range and coverage. Simultaneously, a high-speed solenoid valve opens, and the pressure-adjusted high-pressure gas instantly surges into the explosion chamber at the rear of the launch tube. The increased pressure within the chamber generates a pulse thrust, acting on the launch base of the riot net assembly. This causes the folded riot net and its edge metal counterweights to be launched at high speed. After exiting the launch tube, air resistance and the gravitational torque of the counterweights combine to force the riot net to rapidly unfold into the predetermined mesh shape during its flight trajectory, covering the target area and effectively intercepting and hindering personnel or vehicles approaching from the front.

[0027] Meanwhile, to address the threats to vehicle mobility posed by complex on-site environments, the vehicle is equipped with an emergency support wheel mechanism to enhance survivability. This system is activated immediately when sensors detect or personnel determine that a tire on one side has been punctured or damaged and rendered inoperable. A hydraulic cylinder mounted on the side of an internal cavity in the chassis actuates, pushing a hinged swing arm to rotate downwards in a fan-shaped motion around the axis, thereby releasing a compact support wheel housed within the cavity to the ground. Once fully lowered, the bottom of this support wheel is just below the lowest point of the completely deflated tire profile, allowing partial transfer of the vehicle's weight to the support wheel, providing effective emergency support. This allows the vehicle to escape its disabled state and, relying on the combined action of the remaining intact tires and this emergency support wheel, achieve safe evacuation.

[0028] Furthermore, when the riot control net is launched, the resulting recoil force is transmitted to the slider through the mounting base. This recoil force forces the slider to move backward along the tracks on both sides, away from the launch direction. The movement of the slider directly transmits the recoil force to the magnetorheological damper behind it. During its movement, the slider comes into contact with the metal rod and the ceramic cylinder wound with resistance wire. These two components together form a variable resistor. Referring to the figure, as the slider moves backward, the length of the resistance wire connected to the circuit changes, causing the resistance value of the entire circuit to change. In this embodiment, the greater the recoil displacement, the smaller the resistance value connected to the circuit. After current is applied to the magnetorheological damper, the magnetic particles inside it arrange themselves into a chain structure with a millisecond-level response, causing the liquid to change from a Newtonian fluid to a solid-like structure, increasing its viscosity and thus generating a huge damping force. Through the above feedback mechanism, the magnetorheological damper generates a damping force that matches the recoil impact force. This force converts most of the recoil kinetic energy generated by the launch into the internal energy of the magnetorheological fluid, effectively suppressing the violent vibration and rebound of the launch tube and the entire chamber.

[0029] The operation of all the above functions is centrally controlled and collaboratively managed through a command and communication system integrated within the compartment. Through a unified software interface and hardware interface, this system enables one-key operation and status monitoring of actions such as the telescoping of the expansion compartment, the binding and firing of the launch parameters of the anti-riot net, and the retraction and extension of the emergency support wheels. It realizes the information fusion and linkage of each combat unit, ensures the efficiency of command decision-making and the accuracy of disposal operations, and comprehensively enhances the actual combat effectiveness and deterrence of the police anti-riot command vehicle in complex and sudden tasks.

[0030] The present invention provides a police anti-riot command vehicle, which has the following beneficial effects:

[0031] 1. Through the integrated anti-riot net deployment device and centralized control system, the present invention deeply integrates non-lethal interception means with the command center, achieving seamless connection from situation awareness to rapid disposal. The compressed air drive ensures instant response and controllable force during the launch of the anti-riot net. Combined with the counterweight strip, it ensures the reliable deployment of the net body, enabling efficient and accurate long-range interception of sudden impact events, and greatly enhancing the active defense ability and personnel safety at the command front.

[0032] 2. Through the unique emergency support wheel mechanism of the vehicle, the present invention provides a reliable mechanical solution for the common fatal risk of tire damage and failure. This mechanism can be quickly deployed when the vehicle is damaged to form an effective support, enabling the vehicle to maintain its mobility in extreme situations and achieve safe evacuation. This design significantly enhances the survivability and mission resilience of the command vehicle in complex and dangerous environments, ensuring the continuity of the command chain.

[0033] 3. Through the sideward translatable and expandable compartment structure and precise electric screw drive mechanism of the vehicle, the vehicle can quickly obtain a spacious internal space after parking, providing a comfortable environment for command operations, equipment operation, and personnel rest. This function, together with the anti-riot and emergency mobility systems, is intelligently scheduled by the central controller, reflecting a highly integrated design concept. It makes a single vehicle become a fully functional, responsive, and reasonably laid-out mobile command fortress, comprehensively enhancing the modernization level of police equipment.

[0034] 4. By setting up a recoil transfer structure composed of a magnetorheological damper, a slideway, a variable resistance structure, and a command system, the present invention creatively realizes an adaptive buffering mechanism based on real-time electrical feedback. This system can sense the recoil impact intensity in real time through the displacement of the slide plate and automatically and instantaneously adjust the damping force of the magnetorheological damper, thereby achieving precise and dynamic matching of the recoil buffering force and the impact force. It effectively overcomes the drawbacks of "over-buffering" or "insufficient buffering" of traditional fixed-damping buffering devices when dealing with different launch conditions, significantly enhancing the buffering efficiency and equipment stability, and extending the service life of the launch device and on-vehicle equipment.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please see the appendix Figure 1 - Appendix Figure 10 This invention provides a police riot control command vehicle, including a vehicle chassis 1, a body 2 mounted on the vehicle chassis 1, and a command and communication system 3 mounted inside the body 2, and further including:

[0048] The riot net deployment device 4 is integrated into the top of the compartment 2 and is used to quickly launch and deploy the riot net 402 to the outside of the vehicle.

[0049] An emergency support wheel mechanism 5 is mounted on the vehicle chassis 1 and corresponds to the vehicle tire 6 mounted on the side of the vehicle chassis 1, and is used to provide emergency support when the vehicle tire 6 fails.

[0050] The riot control net deployment device 4 includes a launch tube 401, a riot control net 402 housed in the launch tube 401, and a drive mechanism 403 that provides power for the launch of the riot control net 402. The launch tube 401 is mounted on the top of the housing 2 via a mounting base 404.

[0051] The drive mechanism 403 is a compressed air drive mechanism, which includes a high-pressure gas cylinder 406 fixedly installed at the tail of the launch tube 401. The tail of the launch tube 401 is also provided with an explosion chamber 407. The high-pressure gas cylinder 406 is connected to the explosion chamber 407 in sequence through a pressure regulator 408 and a solenoid valve 409.

[0052] The edge of the riot control net 402 is equipped with a counterweight bar 405.

[0053] Specifically, in the standby state, the riot control net 402 is folded and stored inside the launch tube 401. The counterweights 405 on its edge are used to assist in the rapid deployment of the riot control net 402 after launch, increasing its stability. The high-pressure gas cylinder 406 stores high-pressure inert gas; in this embodiment, nitrogen is used as the launch power source.

[0054] When a launch command is issued via the command and communication system 3, the system first adjusts the rotation angle of the mounting base 404 based on the target distance and environmental factors, aligning the launch tube 401 with the pre-aiming direction. A suitable launch pressure is then set via the pressure regulator 408. The moment the command is issued, the solenoid valve 409 receives the electrical signal and opens instantly. High-pressure gas, after being pressurized by the pressure regulator 408, rapidly enters the explosion chamber 407. The pressure within the explosion chamber 407 increases dramatically, generating a powerful thrust that propels the riot control net 402 and its counterweight 405 as a single unit out of the launch tube 401 at high speed.

[0055] The launched riot net 402, under the combined action of air resistance and the gravitational torque of the counterweight 405, rapidly unfolds into a net-like structure during flight, covering the target area and effectively intercepting or hindering individuals or vehicles impacting from the front. After launch, the solenoid valve 409 closes, allowing the system to be reloaded and inflated in preparation for the next launch. This compressed air-driven method has the advantages of fast response, no open flame, relatively controllable noise, and precisely adjustable power.

[0056] In this embodiment, the initial launch velocity of the riot control net 402 The calculation formula is as follows:

[0057] ;in, The initial launch velocity of the 402 anti-riot net. The internal gas pressure of the explosion chamber 407. The cross-sectional area of ​​the blast cavity 407 is... The length of the launch tube 401, The friction between the riot control net 402 and the inner wall of the launch tube 401, The total mass of the riot control net 402 and the counterweight strip 405;

[0058] This invention calculates the initial launch velocity of the riot control net 402. It accurately matches the target interception distance to avoid insufficient range or exceeding the limit, while controlling the kinetic energy of the riot control net to ensure non-lethal interception safety and prevent excessive impact force from injuring people.

[0059] The emergency support wheel mechanism 5 includes a support wheel 501, a swing arm 502 for retracting and extending the support wheel 501, and a drive component 503 for driving the swing arm 502 to move.

[0060] When not in operation, the support wheel 501, the swing arm 502 and the drive member 503 are housed in the built-in cavity 504 inside the vehicle chassis 1. The drive member 503 is installed on one side of the inner wall of the built-in cavity 504. One end of the swing arm 502 is connected to the drive member 503 and the other end of the swing arm 502 is connected to the support wheel 501.

[0061] The diameter of the support wheel 501 is smaller than the radius of the vehicle tire 6, and its housing position ensures that, in the lowered state, the bottom of the support wheel 501 is lower than the lowest point of the tire profile after the vehicle tire 6 fails.

[0062] Specifically, when the vehicle is in normal operation, the mechanism is in a non-working state, and the support wheel 501, swing arm 502 and drive component 503 are completely housed in the built-in cavity 504 of the vehicle chassis 1, without affecting the vehicle's passability and ground clearance.

[0063] When a vehicle tire 6 is punctured, punched, or completely ineffective for other reasons, the driver or commander can activate the emergency support wheel mechanism 5 through the command and communication system 3. The hydraulic rod of the drive component 503 is activated, pushing or pulling the swing arm 502 to rotate it downwards around the hinge point, thereby swinging the support wheel 501 out of the internal cavity 504 until its bottom is slightly below the lowest point of the profile of the ineffective vehicle tire 6.

[0064] At this point, part of the vehicle's weight is transferred to the support wheel 501, which contacts the ground and, together with the remaining intact tires 6, forms a support. This allows the vehicle to continue moving stably at a low speed, even with completely depressurized tires, thanks to this small support wheel 501, to escape the danger zone and reach a safe location for repairs, greatly enhancing the vehicle's survival and self-rescue capabilities in extreme situations.

[0065] The compartment 2 includes an expandable compartment 201 that can be laterally slid and expanded. The expandable compartment 201 is connected to the main compartment 203 of the compartment 2 through a set of sliding and expanding mechanisms 202.

[0066] The translational extension mechanism 202 drives the extension compartment 201 to switch between the retracted state and the extended state.

[0067] The translational extension mechanism 202 includes a servo motor 204, which is installed inside the main cabin 203. The output end of the servo motor 204 is fixedly connected to a lead screw 205, and the lead screw 205 is externally threaded with a nut 206. The nut 206 is connected to the extension cabin 201, which slides on the bottom wall of the main cabin 203, through an L-shaped rod 207.

[0068] Specifically, when the vehicle is in motion or space is limited, the expansion compartment 201 is in a retracted state, tightly fitting against the main compartment 203 to maintain the vehicle's standard width. When the vehicle arrives on site and needs to be deployed as a command center, the translational expansion mechanism 202 can be activated via the command and communication system 3. Upon receiving the command, the servo motor 204 begins to rotate, driving the lead screw 205, which is fixedly connected to it, to rotate synchronously. The nut 206, threaded onto the lead screw 205, cannot rotate and instead moves linearly along the lead screw 205. The movement of the nut 206 is transmitted to the expansion compartment 201 via the L-shaped rod 207, pushing the expansion compartment 201 to smoothly move laterally along the pre-set guide rail at the bottom of the main compartment 203, thereby significantly expanding the internal space of the compartment 2. After expansion to its final position, the servo motor 204 automatically locks, ensuring the structural rigidity and stability of the expansion compartment 201 in the expanded state. Simultaneously, the flexible seal at the junction of the expansion compartment 201 and the main compartment 203 effectively prevents water and dust damage. This process transforms the command vehicle's interior space from a compact driving configuration to a spacious working configuration, providing the necessary conditions for command operations, equipment operation, and personnel rest. When relocation is required, the servo motor 204 reverses, allowing the extension compartment 201 to be retracted.

[0069] The riot control net deployment device 4, the emergency support wheel mechanism 5, and the translation and expansion mechanism 202 are all electrically connected and centrally controlled by the command and communication system 3 installed in the compartment 2.

[0070] Specifically, the central controller in the command and communication system 3 establishes an electrical connection with the drive units of the riot control net deployment device 4, the emergency support wheel mechanism 5, and the translation extension mechanism 202, such as the solenoid valve 409, the drive component 503, and the servo motor 204, through a wired or wireless local area network.

[0071] The recoil transfer structure 7 includes a transfer seat 701, which is installed on the top of the body 2. The transfer seat 701 has a magnetorheological damper 702 inside. The transfer seat 701 has slides 703 on both sides inside. A metal rod 706 is installed inside one slide 703, and a ceramic cylinder 704 is installed inside the other slide 703. A resistance wire 705 is wound around the outer wall of the ceramic cylinder 704. The metal rod 706 and the outer wall slide of the ceramic cylinder 704 are connected by the same sliding plate 707. The mounting seat 404 is fixed on the top of the sliding plate 707.

[0072] Both the metal rod 706 and the ceramic cylinder 704 have terminal blocks 708 on their outer walls. The terminal blocks 708 are electrically connected to the command and communication system 3 via external lines 709.

[0073] Specifically, when the riot control net is launched, the resulting recoil force is transmitted to the slider 707 through the mounting base 404. This recoil force forces the slider 707 to move backward along the slide rails 703 on both sides, away from the launch direction. The movement of the slider 707 directly transmits the recoil force to the magnetorheological damper 702 behind it. During its movement, the slider 707 comes into contact with the metal rod 706 and the ceramic cylinder 704 with the resistance wire 705 wound around it. These two components together constitute a variable resistor, as detailed in [reference needed]. Figure 10 As the slider 707 moves backward, the length of the resistance wire connected to the circuit changes, altering the overall circuit resistance. In this embodiment, the greater the backward displacement, the smaller the resistance of the connected circuit. After current is applied, the magnetic particles inside the magnetorheological damper 702 arrange themselves into a chain-like structure with a millisecond-level response, transforming the liquid from a Newtonian fluid to a solid-like substance, increasing its viscosity and generating a significant damping force. Through this feedback mechanism, the magnetorheological damper 702 generates a damping force matching the recoil impact. This force converts most of the recoil kinetic energy generated during launch into the internal energy of the magnetorheological fluid, effectively suppressing the violent vibration and rebound of the launch tube 401 and the entire housing 2, transforming the recoil process of the launch device into a smooth, controlled deceleration motion rather than a violent impact.

[0074] Operators can centrally monitor and operate all the above functions through a graphical human-machine interface on the integrated control terminal in the command room. For example, they can click on the target location on the electronic map, and the system will automatically calculate the range and set the firing parameters for the riot control net 402; they can issue an "emergency support" command with one click, and simultaneously lower the support wheels 501 corresponding to multiple damaged tires; they can also control the expansion and retraction of the extension compartment 201. The centralized control mode realizes unified scheduling and coordinated linkage, which greatly improves the operational efficiency, response speed and overall intelligence level of the command vehicle, allowing commanders to focus on tactical decision-making rather than tedious equipment operation.

[0075] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
