Description

Technical Field

[0001] This application relates to the field of vehicle interception and capture equipment, and more particularly to an escape vehicle capture device. Background Technology

[0002] The vehicle capture device is a new type of escape vehicle capture device developed based on the current needs of public security law enforcement. At present, the probability of crimes committed using vehicles is very high, especially the difficulty of forcing escape vehicles to stop and capturing them. When criminals escape, their vehicles are highly mobile and fast due to their unpredictable escape routes, making it difficult for pursuing law enforcement vehicles to catch them. Furthermore, escape vehicles also suppress pursuing law enforcement vehicles, preventing them from overtaking them, which brings great difficulty to stopping crimes and capturing suspects.

[0003] Currently, most vehicle-stopping equipment consists of roadblocks, deflation barriers, and axle-wrapping devices. These devices are designed for vehicles traveling on fixed routes. While some fixed security checkpoints, temporary checkpoints, and check sheds have installed roadblocks, deflation barriers, and axle-wrapping devices, these methods are ineffective against mobile escape vehicles. To address the issue of escape vehicles traveling on unpredictable routes, this mobile vehicle capture device was developed. Summary of the Invention

[0004] This application provides an escape vehicle capture device to solve the problems of existing vehicle-mounted flexible capture technology, such as uncontrollable deployment of the interception net, lack of drag buffer protection, and inability to achieve rapid physical decoupling under extreme conditions.

[0005] This application provides an escape vehicle catcher, including a mounting frame, a landing gear, and an interception net. The mounting frame is fixedly connected to the front of the vehicle, and the landing gear is installed at the end of the mounting frame. The interception net is installed at the end of the landing gear away from the mounting frame, and the two sides of the interception net are connected to the sides of the landing gear through support rods.

[0006] As an improvement, the mounting frame is T-shaped, with mounting bracket lugs on both sides, and a spring rod seat at the connection between the mounting frame and the landing gear. The mounting frame is fixed to the front of the vehicle to provide tension to the entire capture device.

[0007] As an improvement, the landing gear includes a main frame, with sealing plates at the top and bottom of the main frame near the mounting frame. A vehicle-stopping strip is installed on the top of the sealing plate, and a release device is installed at the end of the vehicle-stopping strip near the mounting frame. A top cover is installed on the top of the release device, and an electrical box is installed on the top cover. Fixing sleeves are provided on both sides of the main frame. The main frame serves as the transverse main structure of the entire capture device, ensuring the stability of the connection with the mounting frame.

[0008] As an improvement, the landing gear is connected to the mounting bracket by spring rods. The spring rods are arranged on both sides of the landing gear. One end of each spring rod is connected to a spring rod seat, and the other end is connected to a reinforcing rib on the fixed sleeve. While providing tensile force, the spring rods can also prevent the mounting bracket from pulling off the front bumper of the vehicle when the tensile force is too large, thus avoiding economic losses to the vehicle being installed.

[0009] As an improvement, the main frame is a rectangular frame, with transverse and longitudinal support ribs provided inside the main frame. The number of fixed sleeves on each side is three, which are arranged at the two ends and the middle of the side of the main frame. The fixed sleeves are used to install the support rods. The support rods are expandable multi-stage rods and are fixed in the fixed sleeves under normal conditions. When encountering tensile force, the support rods will expand,卸掉拉力的同时,还能将拦截网发射出去,进行阻车操作。

[0010] As an improvement, the release device includes a chassis, which is mounted on the mounting bracket. A starting arm is installed on the top of the chassis, and a release arm is clamped on the starting arm. A vehicle-blocking belt buckle is installed at the end of the release arm away from the starting arm, and a vehicle-blocking belt is installed on the vehicle-blocking belt buckle. The vehicle-blocking belt is a single-piece binding belt, and its head is connected with a stainless steel vehicle-blocking belt buckle, which is convenient for combination with the release separator.

[0011] As an improvement, the release device is installed in the release device bin. The release device bin is connected to a push rod motor. The emergency release separation device is composed of mechanical and electrical components. The mechanism controls the separation action by a remote control mechanism. The separation device is provided with a connection between the vehicle-blocking belt buckle and the vehicle-blocking belt. In an emergency, the vehicle-blocking belt buckle is disconnected from the main body separation device to achieve the purpose of emergency escape.

[0012] As an improvement, the electrical boxes are symmetrically arranged on both sides of the central axis of the upper cover, and a lock piece starting device is installed inside the electrical boxes.

[0013] As an improvement, the lock piece starting device is connected to the support rod through a gear. The support rod compresses a spring, and a lock core made of stainless steel pipe is provided in the core of the spring. When the telescopic pipe is retracted, the support rod is fixed by the lock core.

[0014] As an improvement, the interception net is in the shape of the Chinese character "Jia". The two sides of the end of the interception net are connected to the support rods. The interception net is triggered by remote control. The front end of the vehicle-blocking belt is square woven and is woven obliquely in a trapezoid. When the vehicle-blocking net contacts the tire, under the action of rotation, the vehicle-blocking net winds around the tire, forming a restriction on the rotation of the tire and a locked state with the axle and suspension components.

[0015] It should be noted that there seems to be an incomplete sentence in the translation of . Please check and correct it if necessary.Compared with the prior art, the advantages of this invention are: remotely triggering the support rod to launch and deploy the interception net, enabling rapid interception and quick deployment while in motion; the flexible inclined woven net wraps around and locks the tires, and the spring rod buffers the tension, reducing collision damage and protecting the vehicle body, ensuring safety and reliability; it has an emergency separation function, in case of danger, the remote-controlled push rod motor causes the vehicle-stopping belt buckle to disengage, instantly cutting off the connection, preventing law enforcement vehicles from being dragged into dangerous situations and ensuring personnel safety.

[0024] like Figures 1-8 An escape vehicle catcher includes a mounting frame 1, a landing gear 2, and an interception net 3. The mounting frame 1 is fixedly connected to the front of the vehicle. The landing gear 2 is installed at one end of the mounting frame 1. The interception net 3 is installed at the end of the landing gear 2 away from the mounting frame 1. The two sides of the interception net 3 are connected to the sides of the landing gear 2 by support rods 4.

[0025] As an improvement, the mounting frame 1 is T-shaped, with mounting frame lugs 11 on both sides. A spring rod seat 12 is provided at the connection between the mounting frame 1 and the landing gear 2. The mounting frame is fixed to the front of the vehicle to provide tension to the entire capture device.

[0026] As an improvement, the landing gear 2 includes a main frame 21. The top and bottom of the main frame 21 near the mounting frame 1 are provided with sealing plates 22. A vehicle-stopping strip 23 is installed on the top of the sealing plate 22. A release device 24 is installed on the end of the vehicle-stopping strip 23 near the mounting frame 1. A top cover 25 is installed on the top of the release device 24. An electrical box 26 is provided on the top cover 25. Fixing sleeves 27 are provided on both sides of the main frame 21. The main frame serves as the transverse main structure of the entire capture device, ensuring the stability of the connection with the mounting frame.

[0027] As an improvement, the landing gear 2 and the mounting frame 1 are connected by a spring rod 5. The spring rod 5 is located on both sides of the landing gear 2. One end of the spring rod 5 is connected to the spring rod seat 12, and the other end is connected to the reinforcing rib on the fixed sleeve 27. While providing tension, the spring rod can also prevent the mounting frame from pulling off the front bumper of the car when the tension is too large, thus preventing economic losses to the vehicle being installed.

[0028] As an improvement, the main frame 21 is a rectangular frame with transverse and longitudinal support ribs on the inner side. There are three fixing sleeves 27 on each side, located at both ends and the middle of the side of the main frame 21. The fixing sleeves are used to install support rods. The support rods are multi-stage rods that can be deployed. Under normal conditions, they are fixed in the fixing sleeves. When they encounter tension, the support rods will deploy. While relieving the tension, they can also launch the interception net to block vehicles.

[0029] As an improvement, the release device 24 includes a chassis 241, which is mounted on the mounting frame 1. An actuation arm 242 is mounted on the top of the chassis 241. A release arm 243 is snapped onto the actuation arm 242. A vehicle-stopping buckle 244 is installed at the end of the release arm 243 away from the actuation arm 242. A vehicle-stopping belt 23 is installed on the vehicle-stopping buckle 244. The vehicle-stopping belt is a single piece of binding strap, and a stainless steel vehicle-stopping belt buckle is connected to the head to facilitate its connection with the release separator.

[0030] As an improvement, the release device 24 is installed in the release device compartment 245, which is connected to the push rod motor 28. The emergency release separation device is composed of mechanical and electrical components. The separation action is controlled by a remote control mechanism. The separation device is equipped with a vehicle-stopping buckle connected to the vehicle-stopping belt. In an emergency, the vehicle-stopping buckle is disengaged from the main separation device to achieve the purpose of emergency escape from danger.

[0031] As an improvement, the electrical box 26 is symmetrically arranged on both sides of the central axis of the upper cover 25, and a locking plate starting device 261 is installed inside the electrical box 26.

[0032] As an improvement, the locking plate starting device 261 is connected to the support rod 4 via gears. The core of the compression spring of the support rod is provided with a lock core made of stainless steel tube. When the telescopic tube is retracted, the support rod is fixed by the lock core.

[0033] As an improvement, the interception net 3 is in the shape of the letter A. The two ends of the interception net 3 are connected to the support rod 4. The interception net 3 is triggered by remote control. The front end of the vehicle blocking belt is square woven and is woven in a trapezoidal diagonal pattern. When the vehicle blocking net comes into contact with the tire, it wraps around the tire under the action of rotation, forming a restraint on the tire rotation with the axle and suspension components and forming a locked state.

[0034] Example: Example 1: landing gear structure The landing gear body is welded from square tubing and stainless steel plates. A storage compartment for the braking band is located in the middle of the landing gear, and a release / separation device is located in the middle of the rear end. Two geared motors are installed on both sides of the rear end to control the opening and locking of the support rods. Two spring-loaded rods are installed on both sides of the upper part of the landing gear to control the retraction and opening of the support rods. Circular lugs are installed on both sides of the rear end of the landing gear to connect the landing gear to the mounting bracket, maintaining the landing gear's 90-degree rotational flexibility.

[0035] Mounting bracket mechanism The main body of the mounting frame is welded from 30mm square tubing, with a lug on each side of the front end, connected to the landing gear by round pins. The rear end of the mounting frame has a 90° structure, and its flat side is fixed to the bottom of the car's front bumper with screws. The vertical side of the mounting frame is fixed to the front of the car's bumper with screws. A lifting motor push rod box is installed on the upper surface of the mounting frame, which houses the push rod motor used to control the landing gear opening action. The two sides of the upper part of the mounting frame are connected to the landing gear via spring push rods, which provide the opening power for the landing gear and control the opening angle.

[0036] Vehicle blocking net Material: Ultra-high molecular weight polyethylene (Kevlar); Structure: The front of the 50mm wide and 3mm thick Kevlar binding strap is woven into a mesh that is 1 meter long and 0.8 meters wide. The other end is a single binding strap. The head is connected to a stainless steel vehicle stop buckle for easy connection with the release separator.

[0037] Length: 30 meters, ensuring a safe distance between law enforcement vehicles and fleeing vehicles.

[0038] Support rod mechanism The support rod is a telescopic mechanism composed of four sections of stainless steel tubes of different diameters.

[0039] Drive method: A spring is installed inside the telescopic tube, and the compression of the spring serves as the power source for the telescopic tube.

[0040] Each section of the support rod is equipped with a mirror and length positioning device to limit the opening length and concentricity. The core of the support rod compression spring is equipped with a lock cylinder made of stainless steel tubing, which secures the support rod when the telescopic tube is retracted. The front end of the support rod has an aluminum ring for connecting to the vehicle barrier net, which is connected to the barrier net with a thin fiber rope. When the tension exceeds the limit, the barrier net detaches from the support rod, forming a normal capture state.

[0041] Remote control system Communication method: Radio frequency (RF) mode, using a frequency of 315 MHz to improve anti-interference capability; Operating range: ≥50 meters, suitable for high-speed pursuit scenarios.

[0042] The remote control operating system consists of 3 channels and 6 buttons. Channel 1 controls the landing gear, with forward and reverse buttons. Channel 2 controls the support rod opening, with forward and reverse buttons. Channel 3 controls the release and separation mechanism, with forward and reverse buttons.

[0043] Emergency separation device The emergency release separation device is composed of mechanical and electrical components, and the separation action is controlled by a remote control mechanism. The separation device is equipped with a vehicle-stopping buckle connected to the vehicle-stopping belt. In an emergency, the vehicle-stopping buckle will detach from the main separation device to achieve the purpose of emergency escape from danger. Separation time: ≤0.5 seconds, ensuring rapid separation.

[0044] Example 2: This embodiment provides a remote-controlled escape vehicle catcher installed at the front of a law enforcement vehicle (such as a police car) for catching illegally fleeing vehicles while in motion, and also has a separation function in emergency situations. The device is primarily mechanical, with the electrical components powered by a 12V power supply.

[0045] I. Overall Equipment Structure and Component Assembly Mounting bracket mechanism Mounting bracket 1 is constructed from 30mm x 30mm square tubing, forming a T-shape with a 90° bend at the rear. During installation, the flat side of mounting bracket 1 is fixed to the bottom of the front bumper of the law enforcement vehicle using screws, and the vertical side is fixed to the front of the vehicle bumper using screws, thus firmly mounting the entire capture device at the front of the vehicle and providing a rearward pulling force. Mounting bracket lugs 11 are welded to both sides of mounting bracket 1, and a spring rod seat 12 is welded to the middle of the front end of mounting bracket 1 (where it connects to the landing gear 2). A push rod motor box is fixedly mounted on the upper surface of mounting bracket 1, housing a push rod motor 28 (a 12V DC motor). The output of push rod motor 28 is connected to a release device compartment 245 to control the raising and lowering of the landing gear 2.

[0046] landing gear mechanism The landing gear 2 serves as the main transverse structure of the entire capture device. Its main frame 21 is a rectangular frame welded from square tubing and stainless steel plates, with transverse and longitudinal support ribs welded to the inside to ensure the stability of the connection with the mounting frame 1. A storage compartment for the vehicle restraint strip 23 is located in the middle of the main frame 21. Sealing plates 22 are bolted to the top and bottom of the main frame 21 near the mounting frame 1. A top cover 25 covers the top surface of the main frame 21, and electrical boxes 26 are symmetrically installed on both sides of the central axis of the top cover 25. The electrical boxes 26 contain a locking plate actuation device 261 (specifically, two 12V geared motors). The output shafts of the geared motors are connected to the support rod 4 via gears to control the locking and unlocking of the support rod 4.

[0047] The main frame 21 has three fixed sleeves 27 welded on both sides, located at both ends and the middle of the main frame 21. The landing gear 2 has circular lugs installed on both sides of the rear end, which are hinged to the mounting bracket lugs 11 at the front end of the mounting bracket 1 by circular pins, so that the landing gear 2 has a 90-degree rotation.

[0048] Flexible connection and support rod mechanism The landing gear 2 and the mounting bracket 1 are connected by two spring rods 5 (i.e., spring top rods). The spring rods 5 are located on both sides of the upper part of the landing gear 2, with one end hinged to the spring rod seat 12 and the other end hinged to the reinforcing rib of the fixing sleeve 27. The spring rods 5 provide tension while also preventing the mounting bracket 1 from pulling off the front bumper of the car when the tension is too large, thus preventing economic losses to the vehicle being mounted.

[0049] The support rod 4 is a multi-stage telescopic mechanism composed of four sections of stainless steel tubes of different diameters. A compression spring is installed inside each telescopic tube as the ejection force. Each section is equipped with mirror and length positioning devices to limit the opening length and ensure concentricity. The core of the compression spring in the support rod 4 has a lock cylinder made of stainless steel tube. When normally retracted, the lock cylinder is locked by a gear driven by a locking plate actuation device 261 (a reduction motor). The front end of the support rod 4 has an aluminum ring connecting to the interception net 3, which is connected to the interception net 3 via a thin fiber rope. When the set tension is exceeded, the thin fiber rope breaks, causing the interception net 3 to detach from the support rod 4, resulting in a normal capture and dragging state.

[0050] Interception net and vehicle blocking mechanism The interception net 3 and the vehicle barrier 23 are an integrated structure, both made of ultra-high molecular weight polyethylene (Kevlar). The front end of the interception net 3 uses 50mm wide and 3mm thick Kevlar binding straps woven into a 1-meter long and 0.8-meter wide mesh structure, employing a square weave and a trapezoidal diagonal braid. The rear end connects to a single binding strap as the main body of the vehicle barrier 23, designed to be 30 meters long. After folding, it is stored in the vehicle barrier storage compartment in the middle of the main frame 21. The head (end) of the vehicle barrier 23 is equipped with a stainless steel square connecting ring, namely the vehicle barrier buckle 244.

[0051] Release device mechanism The release device 24 is installed in the release device compartment 245 at the rear end of the main frame 21, and includes a chassis 241, an actuating arm 242, a release arm 243, and a vehicle-stopping buckle 244. The chassis 241 is fixed to the sealing plate 22, and the actuating arm 242 is mounted on the top via a pivot. The release arm 243 is snapped onto the actuating arm 242, and the vehicle-stopping buckle 244 is attached to the end of the release arm 243. The push rod motor 28 is connected to the actuating arm 242 via a mechanical linkage, forming an emergency release separation device.

[0052] Remote triggering system The equipment is equipped with a wireless radio frequency (RF) remote control mechanism with a communication frequency of 315 MHz and an operating range of ≥50 meters. The remote control has a 3-channel, 6-button design: Channel 1 (forward / reverse button) controls the push rod motor 28 to open / retract the landing gear 2; Channel 2 (forward / reverse button) controls the locking plate activation device 261 (gear motor) to unlock / lock the support rod 4; Channel 3 (forward / reverse button) controls the push rod motor 28 to trigger emergency separation.

[0053] II. Complete Workflow Phase 1: Routine Driving and Concealed Status In non-pursuit mode, the landing gear 2, under the tension of the spring rod 5 and the limit of the push rod motor 28, folds upward at 90 degrees and fits tightly against the mounting frame 1. The support rod 4 retracts into the fixing sleeve 27 and is locked by the locking plate activation device 261; the interception net 3 and the 30-meter-long vehicle barrier 23 are folded and stored in the vehicle barrier storage compartment of the main frame 21, and the vehicle barrier buckle 244 is secured to the release arm 243. The equipment is compact and does not affect the normal driving of law enforcement vehicles.

[0054] Phase Two: Approaching the Target and Deploying Landing Gear When the law enforcement vehicle is tailing and chasing the fleeing vehicle, and the estimated distance is within 10-30 meters, the operator presses the first button of the remote control mechanism. The push rod motor 28 is powered on and starts, pushing the release device compartment 245 and the rear of the landing gear 2 to overcome the tension of the spring rod 5, causing the landing gear 2 to rotate 90 degrees downward around the mounting bracket lug 11 to a horizontal position, waiting for the capture net to open.

[0055] Phase Three: Remote Triggering and Interception Net Launch When the distance and surrounding environment are suitable for capture, the operator presses the second button on the remote control mechanism. The lock-activating device 261 (gear motor) inside the electrical box 26 receives a 315 MHz signal and reverses, unlocking the stainless steel lock cylinder in the support rod 4 core via gear transmission. At the moment the lock cylinder unlocks, the compression spring inside the support rod 4 releases enormous potential energy, pushing the four stainless steel tubes to extend in stages. The support rod 4 rapidly pops forward from the fixing sleeve 27, forming a trapezoidal structure extending forward, simultaneously sending the intercepting net 3 at the front into a combat-ready state, aimed at the rear wheels of the escaping vehicle.

[0056] Phase Four: Entanglement, Locking, and Forced Braking Law enforcement officers accelerated their vehicle, bringing the deployed netting 3 into contact with the rear wheels of the fleeing vehicle. Because the front end of netting 3 features a trapezoidal, diagonally braided structure, the Kevlar mesh quickly entangles itself in the tire's treads under the high-speed rotation of the tires, continuing to wrap around them as the tires spin. The netting 3 tightens, eventually binding the tires with the axle and suspension components, causing them to lock up and lose power.

[0057] At this point, the thin fiber rope at the front end of support rod 4 breaks due to the tension reaching the threshold, and the interception net 3 detaches from support rod 4. The law enforcement vehicle begins to decelerate or brake, while the fleeing vehicle is forced to slow down due to wheel lock-up. As the distance between the two vehicles increases, the 30-meter vehicle-stopping tape 23 folded inside the compartment is gradually pulled out, maintaining a safe distance between the law enforcement vehicle and the fleeing vehicle. The continuous dragging resistance applied by the vehicle-stopping tape 23 forces the fleeing vehicle to eventually stop.

[0058] Phase 5: Emergency Separation (Risk Avoidance Mechanism) During the arrest operation, if the fleeing vehicle goes out of control or deliberately drives towards dangerous areas such as road ditches or cliffs, to prevent the law enforcement vehicle from being dragged into danger, the operator immediately presses the third button on the remote control mechanism. Upon receiving the signal, the push rod motor 28 quickly rotates forward, causing the starting arm 242 inside the release device 24 to deflect, prying open the release arm 243, causing the vehicle-stopping belt buckle 244 (stainless steel square connecting ring) to detach from the main separation device within ≤0.5 seconds. The vehicle-stopping belt 23 instantly separates from the law enforcement vehicle, allowing the vehicle to quickly leave the danger zone, achieving the purpose of emergency escape and ensuring the safety of law enforcement personnel.
