Description

Technical Field

[0001] This invention relates to the field of road barrier technology, and in particular to a multi-stage flexible road barrier system. Background Technology

[0002] Currently, due to the weight and inertia of automobiles and their ability to carry flammable and explosive hazardous materials, the rapid development of automotive technology has placed higher demands on vehicle-stopping mechanisms and systems, forcing roadblock technology to continuously accelerate its development and progress. Commonly used countermeasures include tire spikes, crash barriers, telescopic tire arresters, and flexible winding nets, which have played an important role in stopping vehicles from rushing through. However, with the development and widespread application of technologies such as new energy vehicles, four-wheel drive, pneumatic tires, and tire support systems, current vehicle-stopping mechanisms and systems can no longer meet the needs of real-world missions. They suffer from problems such as limited interception methods, limited effectiveness, and lack of restraint for drivers and passengers. Summary of the Invention

[0003] This invention provides a multi-level flexible vehicle blocking system, which can solve the technical problems of existing road obstacle vehicle blocking methods being singular, having limited blocking effect, and not restraining drivers and passengers.

The first and second support rods are rotatably mounted on both sides of the speed bump body, and the vehicle blocking net is connected to the first and second support rods respectively. A control device is used to control the rotation of the first and second support rods relative to the speed bump body. When the multi-stage flexible vehicle blocking system is in normal traffic condition, the first and second support rods are folded relative to the speed bump body, the vehicle blocking net is housed within the receiving cavity, and the rear wheel blocking device is folded.

The braking plate unlocking device is connected to the speed bump body via the elastic element, and the braking plate is connected to the speed bump body via the rear safety pin. The braking plate unlocking device can drive the braking plate to rotate relative to the speed bump body. Specifically, when the multi-stage flexible braking system is in normal traffic conditions, the braking plate unlocking device is in a folded state under the action of the first and second support rods, and the braking plate is in a folded state under the action of the rear safety pin. When the multi-stage flexible braking system is in a blocking state, the braking plate unlocking device rotates to an unfolded state under the elastic force of the elastic element. When the multi-stage flexible braking system is in a blocking state, the rear safety pin is in an open state, the braking plate unlocking device rotates to a folded state under the action of the vehicle's front wheels, and the braking plate rotates to an unfolded state under the action of the braking plate unlocking device.

[0009] Furthermore, the front stud assembly includes a front stud guard plate, a front safety pin, a front stud, and a front tilting mechanism. The front stud guard plate is connected to the control device, and the front stud is connected to the speed bump body through the front tilting mechanism. When the multi-stage flexible vehicle blocking system is in normal traffic conditions, the front stud guard plate is folded under the action of the control device and the front safety pin. When the multi-stage flexible vehicle blocking system is in a waiting or blocking state, the front safety pin is open, the front stud guard plate is unfolded under the action of the control device, and the front stud flips forward under the action of the front tilting mechanism. Furthermore, the multi-stage flexible vehicle blocking system also includes a first pneumatic push rod and a second pneumatic push rod.

When the multi-stage flexible vehicle blocking system is in a waiting-to-block or blocking state, both the first and second pneumatic push rods are in an extended state, and the first and second support rods are in an unfolded state under the action of the first pneumatic push rod.

[0010] Furthermore, the rear brake spike assembly includes a rear brake spike and a rear tilting mechanism, wherein the rear brake spike is tilted via the rear tilting mechanism.

[0011] Connected to the speed bump body, when the multi-stage flexible vehicle blocking system is in normal passage or waiting to be blocked, the vehicle blocking plate is in a folded state, and the rear vehicle blocking spikes and the rear tilting mechanism are in a folded state under the pressure of the vehicle blocking plate; when the multi-stage flexible vehicle blocking system is in a blocking state and the front wheels of the vehicle have passed the rear vehicle blocking spike assembly, the vehicle blocking plate rotates and unfolds under the action of the vehicle blocking plate unlocking device, and the rear vehicle blocking spikes tilt backward under the action of the rear tilting mechanism.

[0012] Furthermore, the speed bump body is composed of multiple speed bump segments, which are connected by hinges.

[0013] Furthermore, the multi-level flexible vehicle blocking system also includes a monitoring and receiving component, which is used to receive abnormal vehicle information. The monitoring and receiving component is connected to the control device, and can send instructions to the control device to activate the first support rod and the second support rod when it receives abnormal vehicle information.

[0014] The present invention provides a multi-level flexible vehicle blocking system. This system comprises a vehicle blocking net, a front tire-burst wrapping blocking device, a rear tire-burst wrapping blocking device, and a rear wheel blocking device. Through the interaction of these components, it is applicable to various situations. When a vehicle passes through the system, the front of the vehicle first impacts the blocking net, causing it to unfold and form a net bag. The front tire-burst wrapping blocking device punctures the front tires and wraps them around the wheels. The rear wheel blocking device prevents the rear wheels from rolling forward. The speed bump body of the blocking system increases friction with the ground under the vehicle's weight, reducing the distance of sliding forward. When the rear wheels of the vehicle pass through the speed bump body, the rear tire-burst wrapping blocking device punctures the rear tires and wraps them around the wheels. The blocking net can wrap around the entire vehicle or the front of the vehicle, increasing the blocking effect and preventing occupants from escaping. Compared with existing technologies, the multi-level flexible vehicle blocking system provided by this invention uses multiple links and methods to simultaneously restrain the front and rear wheels, as well as the wheels and the vehicle body, to force the vehicle to stop. It can be used individually or in combination, is not limited by road surface, requires no construction, and can be deployed flexibly and quickly. It can effectively prevent drivers and passengers from escaping and effectively solves the technical problems of existing road obstacle vehicle blocking methods being singular, having limited blocking effect, and not restraining drivers and passengers.

[0034] like Figures 1 to 12 As shown, a multi-stage flexible vehicle blocking system is provided according to a specific embodiment of the present invention. This multi-stage flexible vehicle blocking system includes a speed bump body 10, a vehicle blocking net 20, a front tire puncture wrapping and blocking device 30, a rear tire puncture wrapping and blocking device 40, a rear wheel vehicle blocking device 50, a first support rod 60, a second support rod 70, and a control device. The speed bump body 10 has a receiving cavity. The vehicle blocking net 20 is used to wrap at least part of the vehicle. The front tire puncture wrapping and blocking device 30 is disposed on one side of the speed bump body 10 and includes a front tire puncture stud assembly 31 and a front tire puncture wrapping net 32.

[0035] 32 is connected to the front tire spike assembly 31, which is used to puncture vehicle tires. The front tire-damping rope 32 is used to wrap around the wheel to brake the vehicle. The rear tire-damping rope is located on the other side of the speed bump body 10. The rear tire-damping rope includes the rear tire spike assembly 41 and the rear tire-damping rope. The rear tire spike assembly 41 is used to puncture vehicle tires, and the rear tire-damping rope is used to wrap around the wheel to brake the vehicle. The rear wheel braking device 50 includes a braking plate 51 and is rotatably mounted on the speed bump body 10. The rear wheel braking device 50 is used to prevent the vehicle from sliding forward. The first support rod 60 and the second support rod 70 are rotatably mounted on both sides of the speed bump body 10. The tire-damping rope 20 is connected to the first support rod 60 and the second support rod 70 respectively. The control device is used to control the first support rod 60 and the second support rod 70 relative to the speed bump. The rotation of the main body 10; wherein, when the multi-stage flexible vehicle blocking system is in the normal passage state, the first support rod 60 and the second support rod 70 are in a folded state relative to the speed bump main body 10, the vehicle blocking net 20 is housed in the receiving cavity, and the rear wheel vehicle blocking device 50 is in a folded state; when the multi-stage flexible vehicle blocking system is in the blocking state, the first support rod 60 and the second support rod 70 are in an unfolded state relative to the speed bump main body 10, the vehicle blocking net 20 is partially unfolded into a planar blocking state under the drive of the first support rod 60 and the second support rod 70, and the blocking plate 51 of the rear wheel vehicle blocking device 50 is in a folded state; when the multi-stage flexible vehicle blocking system is in the blocking state, the front tire puncture wrapping blocking device 30 is used to puncture and wrap around the front wheel of the vehicle, the vehicle blocking net 20 is unfolded into a three-dimensional shape and wraps around at least part of the vehicle, and the blocking plate 51 of the rear wheel vehicle blocking device 50 is unfolded to prevent the vehicle from sliding forward.

[0036] This configuration provides a multi-level flexible vehicle blocking system, which uses a vehicle blocking net,

[0037] The front tire puncture wrapping device, rear tire puncture wrapping device, and rear wheel blocking device interact with each other to be applicable in multiple situations. When the vehicle being blocked passes through the blocking system, the front of the vehicle first impacts the blocking net, causing it to unfold and form a net bag. The front tire puncture wrapping device completes the tire puncture and wheel entanglement of the vehicle's front tires. The rear wheel blocking device prevents the rear wheels from rolling forward. The speed bump body of the blocking system increases friction with the ground under the weight of the vehicle, reducing the distance of sliding forward. When the rear wheels of the vehicle pass through the speed bump body of the blocking system, the rear tire puncture wrapping device completes the tire puncture and wheel entanglement of the vehicle's rear tires. The blocking net can wrap around the entire vehicle or the front of the vehicle, increasing the blocking effect and preventing the driver and passengers from escaping. Compared with existing technologies, the multi-level flexible vehicle blocking system provided by this invention uses multiple links and methods to simultaneously restrain the front and rear wheels, as well as the wheels and the vehicle body, to force the vehicle to stop. It can be used individually or in combination, is not limited by road surface, requires no construction, and can be deployed flexibly and quickly. It can effectively prevent drivers and passengers from escaping and effectively solves the technical problems of existing road obstacle vehicle blocking methods being singular, having limited blocking effect, and not restraining drivers and passengers.

[0038] Furthermore, in this invention, in order to achieve complete coverage of the vehicle, improve interception efficiency, and effectively and comprehensively...

[0039] To prevent drivers and passengers from escaping, such as Figure 10 As shown, the vehicle blocking net 20 can include a fully enclosed net bag 21a, a first central loop sleeve 22a, a tail loop sleeve 23a, a first side loop sleeve 24a, a second side loop sleeve 25a, a first central tightening rope 26a, a tail tightening rope 27a, a first side tightening rope 28a, and a second side tightening rope 29a. The first central loop sleeve 22a is set in the middle of the fully enclosed net bag 21a via the first central tightening rope 26a, and the tail loop sleeve 23a is set in the tail of the fully enclosed net bag 21a via the tail tightening rope 27a. The first side loop sleeve 24a is set in the middle of the fully enclosed net bag 21a via the first central tightening rope 26a. The shaped sleeve 24a is set on the first side of the fully enclosed net bag 21a via the first side tightening rope 28a, and the second side annular sleeve 25a is set on the second side of the fully enclosed net bag 21a via the second side tightening rope 29a. The first side tightening rope 28a is connected to the first middle tightening rope 26a and the tail tightening rope 27a respectively, and the second side tightening rope 29a is connected to the first middle tightening rope 26a and the tail tightening rope 27a respectively. The first middle tightening rope 26a is connected to the front anti-vehicle winding net 32, and the tail tightening rope 27a is connected to the rear anti-vehicle winding rope.

[0040] In this configuration, when a vehicle collides with the vehicle-blocking net, the fully enclosed net bag unfolds forward, simultaneously...

[0041] The netting wraps around the front of the vehicle. As the vehicle moves forward, the netting gradually covers the entire vehicle. The front wheels are entangled by the front blocking netting, and the rear wheels are entangled by the rear blocking ropes. Because the front blocking netting is connected to the middle tightening rope, and the rear blocking rope is connected to the tail tightening rope, with the first side tightening rope connected to both the middle and tail tightening ropes, and the second side tightening rope connected to both the middle and tail tightening ropes, the netting tightens after the front and rear wheels are wrapped, completely enclosing the vehicle. Simultaneously, the fully wrapped netting, the front blocking netting, and the rear blocking ropes pull and restrain each other, preventing the wheels from rotating and completing the vehicle blocking process. This method achieves all-around vehicle restriction, limiting the rotation of both the front and rear wheels and tightening the vehicle body, improving vehicle interception efficiency and effectively preventing the escape of passengers.

[0042] Alternatively, as another embodiment of the invention, in order to simplify the structure, reduce the size, and save costs, such as Figure 11 As shown, the vehicle blocking net 20 can also include a semi-enclosed net bag 21b, a second central annular sleeve 22b, a second central tightening rope 23b, a third side annular sleeve 24b, a fourth side annular sleeve 25b, a third side tightening rope 26b, and a fourth side tightening rope 27b. The second central annular sleeve 22b is set in the middle of the semi-enclosed net bag 21b via the second central tightening rope 23b. The third side annular sleeve 24b is set on the first side of the semi-enclosed net bag 21b via the third side tightening rope 26b. The fourth side annular sleeve 25b is set on the second side of the semi-enclosed net bag 21b via the fourth side tightening rope 27b. The second central tightening rope 23b is connected to the front vehicle blocking wrapping net 32. The third side tightening rope 26b and the fourth side tightening rope 27b are both connected to the rear vehicle blocking wrapping rope.

[0043] In this configuration, the vehicle-blocking net is simplified to retain only the net bag and lower net structure before the middle tightening rope, eliminating the tail tightening rope to form a simple interception net bag. When a vehicle collides with the vehicle-blocking net, the semi-enclosed net bag unfolds forward, simultaneously wrapping the front of the vehicle. As the vehicle moves forward, the net bag gradually unfolds, but only wraps the front of the vehicle. The front wheels are wrapped by the front vehicle-blocking net, and the rear wheels are wrapped by the rear vehicle-blocking rope. Since the middle tightening rope is connected to the front vehicle-blocking net 32, and the rear vehicle-blocking rope is connected to the side tightening ropes on both sides, after the front and rear wheels are wrapped, the middle tightening rope, as well as the third and fourth side tightening ropes, begin to tighten, tightening the middle and sides of the net bag, semi-enclosing the vehicle. At the same time, the semi-enclosed net bag, the front vehicle-blocking net, and the rear vehicle-blocking rope pull and restrain each other, preventing the wheels from turning, thus completing the vehicle-blocking process. Compared to fully enclosed mesh bags, this method has a simpler structure, only wrapping the front of the vehicle. This effectively tightens the front of the vehicle, preventing people from escaping, and greatly reduces costs and the size of the mesh bag.

[0044] Furthermore, in this invention, in order to improve the tightening effect of the net bag and shorten the interception distance, the vehicle-blocking net can be...

[0045] The 20 is configured to also include a first side extension rope and / or a second side extension rope, the first side extension rope being connected to a first side tightening rope, the second side extension rope being connected to a second side tightening rope, and the first side extension rope and / or the second side extension rope being able to be connected to surrounding objects.

[0046] In this configuration, by setting a first side extension rope and / or a second side extension rope to extend the first side tightening rope and / or the second side tightening rope, and fixing the side extension rope to surrounding objects such as ground posts and trees, the net bag can be tightened more effectively, the stopping distance can be shorter, and the vehicle can be stopped at the set position.

[0047] In this invention, to further improve vehicle blocking efficiency, the rear wheel blocking device 50 can be configured to include a blocking plate 51, a blocking plate unlocking device 52, an elastic element, and a rear safety pin 53. The blocking plate unlocking device 52 is connected to the speed bump body 10 via the elastic element, and the blocking plate 51 is connected to the speed bump body 10 via the rear safety pin 53. The blocking plate unlocking device 52 can drive the blocking plate 51 to rotate relative to the speed bump body 10. When the multi-stage flexible blocking system is in normal traffic conditions, the blocking plate unlocking device 52, in the first... The first support rod 60 and the second support rod 70 are in a folded state, and the vehicle stop plate 51 is in a folded state under the action of the rear safety pin 53. When the multi-stage flexible vehicle stop system is in the blocking state, the vehicle stop plate unlocking device 52 rotates and unfolds under the elastic force of the elastic element. When the multi-stage flexible vehicle stop system is in the blocking state, the rear safety pin 53 is in the open state, the vehicle stop plate unlocking device 52 rotates and folds under the action of the front wheels of the vehicle, and the vehicle stop plate 51 rotates and unfolds under the action of the vehicle stop plate unlocking device 52.

[0048] In this configuration, when the multi-stage flexible vehicle restraint system is in normal traffic condition, it is supported by the first support rod and

[0049] With the second support rod in place, the vehicle stop plate unlocking device is folded and hidden within the speed bump body. The vehicle stop plate 51 is folded under the action of the rear safety pin 53. When the multi-stage flexible vehicle stop system is in the blocking state, the first and second support rods rotate to the upright state, releasing the restriction on the vehicle stop plate unlocking device. Under the action of the elastic element, the vehicle stop plate unlocking device rotates 180° around the pivot and flips upward to the unfolded state. The vehicle stop plate 51 is folded under the action of the rear safety pin 53. When the multi-stage flexible vehicle stop system is in the blocking state, when the front wheels of the vehicle pass through the speed bump body of the vehicle stop system, the front wheels contact the vehicle stop plate unlocking device, causing it to flip downward to the folded state. The rear safety pin 53 opens, and the vehicle stop plate 51 rotates to the unfolded state under the action of the vehicle stop plate unlocking device 52. At this time, the vehicle stop plate 51 and the speed bump body 10 together form an L-shaped blocking structure, preventing the rear wheels from rolling. When the rear wheels of the vehicle press on the speed bump body, the speed bump increases the friction resistance with the ground by the vehicle's own weight, effectively reducing the vehicle speed. In this embodiment, a spring can be used as an elastic element, and the vehicle barrier unlocking device is rotatably mounted on the speed bump body via a rotating shaft.

[0050] In addition, to further reduce vehicle speed, the end of the brake plate 51 can be provided with serrations to puncture the rear tires. The brake plate 51 rotates and unfolds under the action of the brake plate unlocking device 52. The brake plate 51 and the speed bump body form an L-shaped blocking structure to prevent the rear wheels from rolling. When the rear wheels of the vehicle press on the speed bump body, the speed bump increases the friction resistance with the ground by the weight of the vehicle, effectively reducing the vehicle speed.

[0051] Furthermore, in this invention, in order to meet the needs of different vehicle states, the front studs can be retracted during normal passage to prevent puncturing the front wheels, and can be rotated to expose the front studs when interception is required. The front stud assembly 31 can be configured to include a front stud guard 311, a front safety pin 312, a front stud 313, and a front flipping mechanism 314. The front stud guard 311 is connected to the control device, and the front stud 313 is connected to the speed bump body 10 through the front flipping mechanism 314. When the multi-stage flexible vehicle blocking system is in the normal passage state, the front stud guard 311 is in a folded state under the action of the control device and the front safety pin 312. When the multi-stage flexible vehicle blocking system is in the waiting or blocking state, the front safety pin 312 is in an open state, the front stud guard 311 is in an unfolded state under the action of the control device, and the front stud 313 is flipped forward by the action of the front flipping mechanism 314.

[0052] In this configuration, when the multi-stage flexible vehicle blocking system is in normal traffic condition, the front stud guard 311 is folded under the action of the control device and the front safety pin 312. When the multi-stage flexible vehicle blocking system is in the blocking state or the blocking state, the control device controls the front stud guard to rotate and open. The front studs 313 are flipped forward by the front flipping mechanism 314, exposing the studs. When a wheel passes by, the studs can penetrate the front wheel of the vehicle to block it. As a specific embodiment of the present invention, the front flipping mechanism 314 may consist of a front stud fixing seat, a front rotating shaft, and a front torsion spring. The front studs 313 are spaced apart on the front stud fixing seat. The front flipping mechanism 314 flips the front studs 313 upwards, facing the front wheel of the vehicle, by the force of the torsion spring.

[0053] In this invention, to achieve rotation of the first and second support rods relative to the speed bump body, considering the complexity of the manufacturing process and the ease of implementation, the multi-stage flexible vehicle blocking system can be configured to further include a first pneumatic push rod 80 and a second pneumatic push rod 90. The first pneumatic push rod 80 is connected to the first support rod 60 and the speed bump body 10, respectively, and the second pneumatic push rod 90 is connected to the second support rod 70 and the speed bump body 10, respectively. When the multi-stage flexible vehicle blocking system is in a normal passage state, both the first pneumatic push rod 80 and the second pneumatic push rod 90 are in a compressed state, and both the first support rod 60 and the second support rod 70 are in a folded state. When the multi-stage flexible vehicle blocking system is in a waiting-to-block state and a blocking state, both the first pneumatic push rod 80 and the second pneumatic push rod 90 are in an extended state, the first support rod 60 is in an unfolded state under the action of the first pneumatic push rod 80, and the second support rod 70 is in an unfolded state under the action of the second pneumatic push rod 90.

[0054] Furthermore, in this invention, in order to meet the needs of different vehicle states, the rear tire spikes can be retracted during normal passage to prevent puncturing the front wheels, and can be rotated to expose the rear tire spikes to puncture the rear wheels of the vehicle when interception is required. The rear tire spike assembly 41 can include a rear tire spike 411 and a rear flipping mechanism 412. The rear tire spike 411 is connected to the speed bump body 10 through the rear flipping mechanism 412. When the multi-stage flexible vehicle blocking system is in a normal passage or waiting-to-intercept state, the vehicle blocking plate 51 is in a folded state, and the rear tire spike 411 is in a folded state under the pressure of the vehicle blocking plate 51. When the multi-stage flexible vehicle blocking system is in an interception state and the front wheels of the vehicle have passed the rear tire spike assembly, the vehicle blocking plate 51 rotates and unfolds under the action of the vehicle blocking plate unlocking device 52, and the rear tire spike 411 flips backward under the action of the rear flipping mechanism 412.

[0055] In this configuration, when the multi-stage flexible vehicle blocking system is in normal passage or waiting-to-be-blocked state, the blocking plate 51 is in a folded state, applying downward pressure to the rear tire tether and the rear tilting mechanism. The rear tire tether 411 is folded under the pressure of the blocking plate 51. When the multi-stage flexible vehicle blocking system is in the blocking state and the front wheels of the vehicle have passed the rear tire tether assembly, the blocking plate 51 rotates and unfolds under the action of the blocking plate unlocking device 52, releasing the pressure applied to the rear tire tether and the rear tilting mechanism. The rear tire tether 411 is tilted backward under the action of the rear tilting mechanism 412, exposing the rear tire tether. When the wheels pass, the rear tire tether can pierce the rear wheel of the vehicle to block the vehicle. This method can ensure that the front wheels of the vehicle can pass smoothly through the rear tire puncture and wrapping device in the blocking state, while also puncturing the rear wheel of the vehicle when the front wheel is punctured and wrapped by the front tire puncture and wrapping device. As a specific embodiment of the present invention, the rear tilting mechanism 412 consists of a rear brake pin fixing seat, a rotating shaft and a torsion spring. The rear brake pins 411 are spaced apart on the rear brake pin fixing seat. The rear tilting mechanism 412 flips the rear brake pins 411 upwards to face the rear wheel of the vehicle by the force of the torsion spring.

[0056] Furthermore, in this invention, the speed bump body 10 is composed of multiple speed bump segments, which are connected by hinges.

[0057] The chains are connected. As a specific embodiment of the present invention, such as... Figure 4As shown, any two adjacent speed bump segments are connected by a hinge structure 100. Each adjacent speed bump segment has an interface pin and an interface. When storage is required, multiple speed bump segments can be folded sequentially. Each adjacent speed bump segment has an interface pin 140 and an interface 150, which engage to achieve linkage. A storage locking ring is also provided on each adjacent speed bump segment, which locks and secures each segment after folding. This method facilitates folding and storage, making it easy to carry.

[0058] In addition, in this invention, the speed bump body is also provided with fixing nail holes, which can be fixed to the ground by the speed bump fixing nails 120 when needed, so as to shorten the stopping distance.

[0059] Furthermore, in this invention, in order to quickly intercept suspected vehicles, the multi-level flexible vehicle blocking system can be configured to also include a monitoring and receiving component. The monitoring and receiving component is used to receive abnormal vehicle information. The monitoring and receiving component is connected to the control device. When the monitoring and receiving component receives abnormal vehicle information, it can send a command to the control device to make the first support rod 60 and the second support rod 70 move.

[0060] As a specific embodiment of the present invention, the monitoring and receiving component includes a wireless signal interface and a monitor. The multi-level flexible vehicle blocking system receives abnormal vehicle information through the wireless signal interface. When a suspect vehicle or an abnormal vehicle passes by, the automatic control system unlocks. The control device sends a signal through the wired and wireless controllers to operate the unlocking mechanism to unlock the first support rod and the second support rod. The first support rod and the second support rod pop up and stand upright, causing the vehicle blocking net to partially open and form a vehicle blocking net wall. The front vehicle blocking spike guard plate pops up and provides support, exposing the front vehicle blocking spikes, and the system is in a vehicle blocking state.

[0061] To gain a further understanding of the present invention, the following description is provided in conjunction with... Figures 1 to 6 The multi-stage flexible vehicle braking system provided by this invention will be described in detail.

[0062] like Figures 1 to 6 As shown, a multi-stage flexible vehicle blocking system is provided according to a specific embodiment of the present invention. The multi-stage flexible vehicle blocking system includes a speed bump body 10, a vehicle blocking net 20, a front tire puncture entanglement blocking device 30, a rear tire puncture entanglement blocking device 40, a rear wheel vehicle blocking device 50, a first support rod 60, a second support rod 70, a control device, a first pneumatic push rod 80, a second pneumatic push rod 90, a hinge structure 100, a locking ring 110, and a speed bump fixing nail 120. The control device includes a remote controller, a control motor, an unlocking mechanism, a wired and wireless signal interface, and a power supply.

[0063] The speed bump body 10 consists of three speed bump segments connected by a hinge structure 100. When needed for storage, the segments can be folded sequentially. A storage locking ring 110 is provided on any two adjacent segments to lock and secure them after folding. The speed bump body also has holes for fixing ground spikes, allowing it to be fixed to the ground with speed bump fixing nails 120 when needed, thus shortening the stopping distance.

[0064] The speed bump body 10 has a receiving cavity, and the vehicle blocking net 20 can be accommodated and installed within the receiving cavity. The vehicle blocking net 20 includes a fully enclosed net bag 21a, a first central annular sleeve 22a, a tail annular sleeve 23a, a first side annular sleeve 24a, a second side annular sleeve 25a, a first central tightening rope 26a, a tail tightening rope 27a, a first side tightening rope 28a, and a second side tightening rope 29a. The first central annular sleeve 22a is installed in the middle of the fully enclosed net bag 21a via the first central tightening rope 26a, and the tail annular sleeve 23a is installed at the tail of the fully enclosed net bag 21a via the tail tightening rope 27a. The first side annular sleeve 24a, the tail annular sleeve 25a, the tail annular sleeve 26a, the tail annular sleeve 27a, the tail annular sleeve 28a, the tail annular sleeve 29a, the tail annular sleeve 21 ... 4a is attached to the first side of the fully enclosed mesh bag 21a via the first side tightening rope 28a, and the second side annular sleeve 25a is attached to the second side of the fully enclosed mesh bag 21a via the second side tightening rope 29a. The first side tightening rope 28a is connected to the first middle tightening rope 26a and the tail tightening rope 27a respectively, and the second side tightening rope 29a is connected to the first middle tightening rope 26a and the tail tightening rope 27a respectively. The first middle tightening rope 26a is connected to the front anti-vehicle winding net 32, and the tail tightening rope 27a is connected to the rear anti-vehicle winding rope. The first middle tightening rope 26a and the tail tightening rope 27a are connected to the side tightening ropes via four connection points in the middle and four connection points at the tail respectively.

[0065] When the multi-level flexible vehicle blocking system is in normal traffic conditions, the vehicle blocking net is completely contained within the speed bump.

[0066] Inside the main body 10; when the multi-stage flexible vehicle blocking system is in the blocking state, the first support rod 60 and the second support rod 70 spring up and stand upright. The upper end and the two side net bags of the vehicle blocking net 20 are folded and stored on the blocking net pivot 130 and the support rod, supporting the partially opened net bags, and the lower end is folded and stored in the speed bump body. When the multi-stage flexible vehicle blocking system is in the blocking state, when the front vehicle blocking net 32 ​​wraps around the front wheel, the first middle tightening rope 26a can be tightened, and then the tightening ropes on both sides of the net bag can be tightened through the first middle tightening rope 26a, thereby tying the middle and both sides of the net bag, so that the front of the vehicle is tightened longitudinally and laterally. When the rear vehicle blocking nail punctures the tire and wraps around the rear wheel, the tail tightening rope 27a can be tightened, and then the tightening ropes on both sides of the net bag can be tightened through the tail tightening rope 27a, thereby tying the tail and both sides of the blocking net, so that the entire vehicle is tightened. When the front and rear vehicle-blocking ropes wrap around the wheels, the first middle tightening rope 26a, the tail tightening rope, and the side tightening ropes of the interception net can be tightened, thereby tightening the middle and rear net bags of the interception net, so that the front and rear wheels, and the wheels and the vehicle body restrain each other and work together to force the vehicle to slow down and stop.

[0067] In addition, in this embodiment, the tightening ropes on the left and right sides can be extended. When necessary, the extended ropes can be fixed to surrounding objects such as ground pillars and trees to make the net bag tighten better and the stopping distance shorter.

[0068] The front tire puncture arrestor 30 includes a front stud assembly 31 and a front tire traction net 32. The front tire traction net 32 ​​is connected to the front stud assembly 31. The front stud assembly 31 is used to puncture the vehicle tire, and the front tire traction net 32 ​​is used to wrap around the wheel to brake the vehicle. The front stud assembly 31 includes a front stud guard 311, a front safety pin 312, a front stud 313, and a front tilting mechanism 314. The front stud guard 311 is connected to a control device, and the front stud 313 is connected to the speed bump body 10 through the front tilting mechanism 314. The front stud guard 311 is rotatably mounted on the speed bump body 10 via a front stud guard shaft 315. The front stud guard 311 consists of two first front stud guards 3111 and one second front stud guard 3112. When the multi-stage flexible tire puncture arrestor system is in operation... In normal traffic conditions, the front stud guard 311 is folded under the control of the control device and the front safety pin 312, covering the front studs 313 and ensuring that normal vehicle passage is not affected. When the multi-stage flexible vehicle blocking system is in the blocking or interception state, the front safety pin 312 is open. Under the control of the control device, the two first front stud guards 3111 unfold outward, and the second front stud guard 3112 opens forward. The front studs 313 are flipped forward 90° by the front flipping mechanism 314, releasing the restriction on the front studs. Specifically, in this embodiment, the front flipping mechanism 314 may consist of a front stud fixing seat, a front rotating shaft, and a front torsion spring. The front studs 313 are spaced apart on the front stud fixing seat. The front flipping mechanism 314 flips the front studs 313 upward, facing the front wheels of the vehicle, through the torsion spring force.

[0069] A rear tire puncture prevention device 40 is disposed on the other side of the speed bump body 10. The rear tire puncture prevention device 40 includes a rear tire spike assembly 41 and a rear tire puncture winding rope. The rear tire spike assembly 41 is used to puncture the vehicle tire, and the rear tire puncture winding rope is used to wrap around the wheel to brake the vehicle. A rear wheel braking device 50 is rotatably disposed on the speed bump body 10 and is used to prevent the vehicle from sliding forward. A first support rod 60 and a second support rod 70 are respectively rotatably disposed on both sides of the speed bump body 10. A control device is used to control the rotation of the first support rod 60 and the second support rod 70 relative to the speed bump body 10. The rear bumper assembly 41 includes rear bumper spikes 411 and a rear flipping mechanism 412. The rear bumper spikes 411 are connected to the speed bump body 10 through the rear flipping mechanism 412. When the multi-stage flexible bump system is in normal passage or waiting to be blocked, the bump plate 51 is in a folded state, and the rear bumper spikes 411 are folded under the pressure of the bump plate 51. When the multi-stage flexible bump system is in a blocking state and the front wheels of the vehicle have passed the rear bumper assembly, the bump plate 51 rotates and unfolds under the action of the bump plate unlocking device 52, and the rear bumper spikes 411 are flipped 90° backward under the action of the rear flipping mechanism 412. The rear flipping mechanism 412 consists of a rear bumper spike fixing seat, a rotating shaft, and a torsion spring. The rear bumper spikes 411 are spaced apart on the rear bumper spike fixing seat. The rear flipping mechanism 412 flips the rear bumper spikes 411 upward, facing the rear wheels of the vehicle, through the force of the torsion spring.

[0070] The rear wheel braking device 50 includes a wheel braking plate 51, a wheel braking plate unlocking device 52, an elastic element, and a rear safety pin 53, which brakes the wheel.

[0071] The plate unlocking device 52 consists of a vertical plate and a vertical plate pivot. The vertical plate is connected to the speed bump body 10 via an elastic element, and the vehicle blocking plate 51 is connected to the speed bump body 10 via a rear safety pin 53. The vertical plate can drive the vehicle blocking plate 51 to rotate relative to the speed bump body 10. When the multi-stage flexible vehicle blocking system is in normal passage, the vertical plate is folded under the action of the first support rod 60 and the second support rod 70, and is hidden inside the speed bump body. The vehicle blocking plate 51 is folded under the action of the rear safety pin 53. When the multi-stage flexible vehicle blocking system is in the blocking state, the first support rod and the second support rod stand up to release the restriction on the vertical plate. Under the elastic force of the elastic element, the vertical plate rotates 180° around the vertical plate pivot and flips upward. When the multi-stage flexible vehicle blocking system is in the blocking state and the front wheels of the vehicle have passed the rear vehicle blocking spike assembly, when the front wheels of the vehicle pass the speed bump body of the vehicle blocking system, they contact the vertical plate and cause it to flip, thus unlocking the vehicle blocking plate. The upper part of the brake plate is equipped with serrations to puncture the rear tires. After the brake plate pops open, it forms an L-shaped blocking structure with the speed bump, preventing the rear wheels from rolling. When the rear wheels of the vehicle run over the speed bump body, the speed bump body increases the friction resistance with the ground by the weight of the vehicle, effectively reducing the vehicle speed.

[0072] The control device consists of a remote controller, a control motor, an unlocking mechanism, wired and wireless signal interfaces, and a power supply.

[0073] The wired and wireless controllers send signals to control the unlocking mechanism to unlock the first and second support rods. The first and second support rods pop up and stand upright, causing the vehicle blocking net to partially open and form a vehicle blocking net wall. The front vehicle blocking spike guard plate pops out and provides support, exposing the front vehicle blocking spikes, and the system is in the vehicle blocking state.

[0074] Specifically, in this embodiment, when the multi-level flexible vehicle blocking system is in normal traffic condition, the vehicle blocking net 20, vehicle blocking plate 51, front vehicle blocking spike 313 and rear vehicle blocking spike 411 are in a retracted state, and their appearance is similar to that of a normal speed bump. They can be on standby in key areas and important checkpoints; they can also be folded and moved quickly, and the retracted state is convenient for carrying.

[0075] Upon receiving a vehicle interception command, the control device can unlock the first support rod 60, the second support rod 70, and the front vehicle stud guard plate 311 via an electric mechanism. The first support rod 60 and the second support rod 70 spring up and stand upright, unfolding the vehicle interception net 20 via the first support rod 60 and the second support rod 70. The upper end and side net bags of the vehicle interception net 20 are folded and stored on the interception net pivot 130 and the support rods, supporting the partially opened net bags, while the lower end is folded and stored inside the speed bump body 10. The front vehicle stud 313 is exposed, completing the fixed-point deployment.

[0076] When a vehicle crashes into the vehicle-blocking net 20, the net unfolds forward, simultaneously wrapping around the front of the vehicle. As the front wheels pass over the speed bump, the anti-vehicle plate 51 and the rear anti-vehicle spike 411 are released, and the front wheels are pierced by the front anti-vehicle spike 313. As the vehicle continues forward, the net gradually wraps around the entire vehicle. When the rear wheels reach the speed bump, the anti-vehicle plate 51 restricts their forward rolling. The speed bump 10 effectively slows down the vehicle by using its weight and friction with the ground, while the rear wheels are pierced by the rear anti-vehicle spike 411. As the vehicle continues forward, the front and rear wheels are wrapped by the front anti-vehicle wrapping net 32 ​​and the rear anti-vehicle wrapping rope, respectively. The middle tightening rope, the tail tightening rope, and the side tightening ropes begin to tighten and secure the net bag, wrapping the vehicle. At the same time, the net bag, the front anti-vehicle wrapping net 32, and the rear anti-vehicle wrapping rope pull and restrain each other, preventing the wheels from turning, thus completing the vehicle-blocking process.

[0077] In summary, this invention provides a multi-stage flexible vehicle blocking system. During the process of an intercepted vehicle passing through the system, the front of the vehicle first impacts the netting of the vehicle blocking net, causing it to unfold and form a net bag. When the front wheels of the vehicle pass over the speed bump body of the vehicle blocking system, the front of the vehicle enters the pre-designed net bag. The front tire-puncture and wheel-wrapping interception device completes the tire puncture and wheel entanglement of the front wheels, while simultaneously tightening the central tightening rope, activating the rear wheel blocking device and the rear tire-puncture and wheel-wrapping interception device. When the rear wheels of the vehicle press on the speed bump body of the vehicle blocking system, the rear wheel blocking device prevents the rear wheels from rolling forward. Under the weight of the vehicle, the speed bump body of the vehicle blocking system increases friction with the ground, reducing the sliding forward distance. When the rear wheels of the vehicle pass over the speed bump body of the vehicle blocking system, the rear tire-puncture and wheel-wrapping interception device completes the tire puncture and wheel entanglement of the rear wheels, while simultaneously tightening the interception net to form a tightened net bag. The net bag can wrap around the entire vehicle or the front of the vehicle, increasing the vehicle blocking effect and preventing the escape of passengers. Compared with existing technologies, the multi-level flexible vehicle blocking system provided by this invention can wrap around the entire vehicle or the front of the vehicle, increasing the vehicle blocking effect. It can flexibly and effectively control suspicious and abnormal vehicles and drivers and passengers. The folding form is more conducive to quick carrying and deployment, and can be used for vehicle blocking in a variety of scenarios.

[0078] For ease of description, spatial relative terms such as "above" or "above" can be used here.

[0079] Terms such as "on the upper surface of," "above," etc., are used to describe the spatial positional relationship of a device or feature as shown in the figure to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation, in addition to the orientation of the device as described in the figure. For example, if a device in the figure is inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0080] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0081] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
