Description

Technical Field

[0001] This invention relates to the field of road public safety facilities technology, and more specifically, to a highway safety anti-reverse driving device and its anti-reverse driving system. Background Technology

[0002] As urban traffic networks become increasingly complex, drivers often choose to take shortcuts and drive against traffic because they have to take longer routes. This not only endangers their own safety but may also have serious consequences for the safety of other vehicles and people.

[0003] Currently, the common principle behind anti-back-traffic devices is that a one-way tiltable, sharp barb or metal structure allows a vehicle traveling in the correct direction to push the barb or metal structure into the ground and pass smoothly. Vehicles traveling in the wrong direction will have their tires punctured by this structure, thus preventing them from traveling against the flow of traffic. While this device effectively prevents vehicles from traveling against the flow of traffic, it also poses public safety risks. The sharp points above the road surface, while deterring vehicles traveling in the wrong direction, also endanger pedestrians and non-motorized vehicles traveling normally. It can easily cause damage to vehicles traveling in the wrong direction, such as tire punctures, vehicle tipping, or rollovers, severely endangering the driver's personal safety.

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed merely to enable those skilled in the art to better understand and implement the subject matter described herein. Furthermore, features described in some examples may be combined in other examples.

[0019] like Figures 1 to 7 As shown, a highway safety anti-reverse driving device includes: Several interception units are deployed sequentially along the width of the highway; The interception unit includes a slide rail 1, an arc-shaped base 2 mounted on the slide rail 1, two arc-shaped side plates 4 detachably connected to both sides of the arc-shaped base 2, a rotating interception plate 3 movably connected between the two arc-shaped side plates 4, an adjustable elastic support mechanism 5 connected between the arc-shaped base 2 and the rotating interception plate 3, and an adjustable energy dissipation mechanism 6 located at the bottom of the arc-shaped base 2. The arc-shaped base 2 is slidably connected to the slide rail 1 through the adjustable energy dissipation mechanism 6. The slide rail 1 is pre-embedded along the length of the highway. The adjustable elastic support mechanism 5 includes a translation component on the arc-shaped base 2 and several telescopic elastic support components connected between the translation component and the rotating interceptor plate 3. The translation component is used to drive the movable ends of the several telescopic elastic support components to move synchronously a set distance along the length of the road. The telescopic elastic support components are used to adjust the angle between the rotating interceptor plate 3 and the horizontal plane. The adjustable energy unloading mechanism 6 includes a friction-type energy unloading component located at the bottom of the arc-shaped base 2, two sets of friction force adjustment components symmetrically connected to the friction-type energy unloading component, and a bidirectional drive component located at the bottom of the arc-shaped base 2. The friction-type energy unloading component is slidably connected to the slide rail 1. The bidirectional drive component is used to drive the two sets of friction force adjustment components to move closer or further apart from each other. The friction force adjustment component is used to adjust the friction force between the friction-type energy unloading component and the slide rail 1.

[0020] It should be noted that during installation, a pre-buried pit needs to be dug at the corresponding location on the highway to house and fix the slide rail 1. Since the slide rail 1 is pre-buried underground, it will not come into contact with vehicles traveling on the ground. Vehicles traveling in the same direction will first have their wheels contact the point where the rotating interceptor plate 3 is movably connected to the curved side plate 4. Under normal conditions, the translation component controls the movable ends of several telescopic elastic support components to be in a set position. At this time, the rotating interceptor plate 3 rotates a set angle around the axis of its movable connection with the curved side plate 4, meaning its other free end tilts up by a set angle. When the wheels of a vehicle traveling in the same direction run over the rotating interceptor plate 3, the plate rotates around its movable connection with the arc-shaped side plate 4, thus returning to its combined state with the arc-shaped base 2. This continues until the rear wheels of the vehicle leave, at which point the rotating interceptor plate 3, under the elastic force of several telescopic elastic support components, returns to its raised state. However, some drivers, unfamiliar with the road conditions or unaware of the anti-back-driving device, may still drive in the wrong direction. In such cases, the front wheels of their vehicle will first contact the raised end of the rotating interceptor plate 3, causing the plate to... 3. The wheel of the vehicle is limited and blocked, which can effectively prevent the vehicle from directly leaving the rotating interceptor plate 3 and the arc-shaped base 2. When the vehicle is traveling in the opposite direction at a certain speed, the adjustable energy-relieving mechanism 6 set at the bottom of the arc-shaped base 2 can adjust the friction damping between it and the slide rail 1. So that after the vehicle contacts the rotating interceptor plate 3, it pushes the rotating interceptor plate 3 and the arc-shaped base 2 to move in the same direction. During this movement, a certain amount of friction loss is generated to offset part of the kinetic energy of the current vehicle, which can assist the current vehicle in stabilizing braking. This can effectively reduce the possibility of the rear of the vehicle overturning, thus effectively ensuring the safety performance of the current vehicle and preventing personal danger to the driver or passengers in the vehicle. When the adjustable energy-relieving mechanism 6 adjusts the friction, it drives the two sets of friction force adjustment components to move closer to each other through the bidirectional drive component. At this time, the friction force adjustment component begins to increase the pressure applied to the friction energy-relieving component. This pressure is transmitted to the slide rail 1 through the friction energy-relieving component, thereby increasing the friction between the friction energy-relieving component and the slide rail 1, thus achieving stable braking of vehicles at different speeds within the set stroke.

[0021] In an optional embodiment of the invention, such as Figures 1 to 7As shown, the translation component includes a movable chamber 501 disposed within the arc-shaped base 2, several sliding grooves 502 penetrating the movable chamber 501, a movable plate 503 slidably connected to the inner wall of the movable chamber 501, a motor 510 fixedly mounted on the arc-shaped base 2, a gear 511 connected to the output shaft end of the motor 510, a screw 514 movably connected to the inner wall of the movable chamber 501, a second gear 512 connected to one end of the screw 514 located outside the movable chamber 501, and a chain 513 connected between the first gear 511 and the second gear 512. The movable plate 503 is threadedly connected to the hinge frame 504, and the movable ends of several telescopic elastic support components pass through the corresponding sliding grooves 502 and are fixedly connected to the movable plate 503.

[0022] The telescopic elastic support assembly includes a first hinge frame 504, a second hinge frame 505 hinged to the first hinge frame 504, a telescopic rod 506 fixedly connected to the second hinge frame 505, a third hinge frame 507 fixedly connected to the other end of the telescopic rod 506, a fourth hinge frame 508 hinged to the third hinge frame 507, and a first spring 509 fixedly connected between the second hinge frame 505 and the third hinge frame 507. The first hinge frame 504 passes through a corresponding slide groove 502 and is fixedly connected to a moving plate 503. The fourth hinge frame 508 is fixedly connected to a rotating interceptor plate 3.

[0023] It should be noted that, as mentioned above, because different vehicles have different chassis ground clearance and wheel diameters, the tilting degree of the rotating interceptor plate 3 needs to be adjusted for different vehicles to adapt to blocking different vehicles. When adjusting the tilting degree of the rotating interceptor plate 3, the motor 510 drives the gear 511 to rotate. After the gear 511 rotates, it drives the gear 512 to rotate synchronously through the chain 513. When the gear 512 rotates, it drives the screw 514 to rotate synchronously. Because the moving plate 503 is threadedly connected to the screw 514 and its movement... The interior of chamber 501 is confined, so when screw 514 rotates, it can drive movable plate 503 to move along the length of screw 514. During this process, movable plate 503 can drive hinge frame 504 connected to it to move in the same direction and at the same distance. When hinge frame 504 moves, hinge frame 505 can rotate around the movable connection point with hinge frame 504. The other end of telescopic rod 506 fixedly connected to hinge frame 505 is fixedly connected to hinge frame 507, and hinge frame 508 is fixedly connected to rotating interceptor plate 3. When the connecting frame 504 moves, the hinge frame 507 also rotates around its rotatable connection with the hinge frame 508, causing a change in the angle between the entire telescopic rod 506 and the horizontal plane. Under the elastic force of the spring 509, the rotating interceptor plate 3 rotates around its movable connection with the arc-shaped side plate 4, thus changing the tilt angle of the free end of the rotating interceptor plate 3. This changes the angle between the rotating interceptor plate 3 and the horizontal plane, allowing the rotating interceptor plate 3 to intercept larger diameter wheels while preventing vehicles traveling in the same direction from entering. When a vehicle runs over the rotating interceptor plate 3, the rotating interceptor plate 3 rotates around the connection point with the arc-shaped side plate 4 under force, and transmits the component of the pressure to the hinge frame 4 508. The hinge frame 4 508 transmits the pressure to the hinge frame 3 507. At this time, the telescopic rod 506 and the spring 1 509 are compressed and adjusted to the angle with the horizontal plane, tilting towards the gap between the rotating interceptor plate 3 and the arc-shaped base 2. Thus, the rotating interceptor plate 3 can completely cover the arc-shaped base 2 and form a complete arc structure with the arc-shaped base 2, allowing the vehicle in the same direction to drive away smoothly.

[0024] In an optional embodiment of the invention, such as Figures 1 to 7 As shown, the friction-type energy dissipation assembly includes a second movable chamber 601 disposed in the arc-shaped base 2, a second slide groove 602 disposed at the bottom of the arc-shaped base 2 and communicating with the second movable chamber 601, and two damping limit frames 605 symmetrically disposed in the second movable chamber 601. The limiting damping part of the damping limit frame 605 passes through the second slide groove 602 and is limited and engaged with the slide rail 1.

[0025] The friction adjustment assembly includes a second movable plate 606 and a second spring 607 connected to the second movable plate 606. The second movable plate 606 is slidably connected to the inner wall of the second movable chamber 601, and the other end of the second spring 607 is fixedly connected to the corresponding damping limit bracket 605.

[0026] The bidirectional drive assembly includes a second motor 603 and a second screw 604 connected to the output shaft end of the second motor 603. The second motor 603 is fixedly installed in the second movable chamber 601. The second screw 604 is provided with two sets of threads with opposite directions of rotation. The two sets of threads are symmetrically arranged. The second movable plate 606 is provided with threaded holes that mate with the corresponding threaded parts. The damping limit bracket 605 is provided with through holes through which the second screw 604 passes.

[0027] It should be noted that, as mentioned above, after the rotating interceptor plate 3 intercepts the vehicle wheels, it is subjected to force and moves with the vehicle. As the rotating interceptor plate 3 moves with the vehicle, it can carry the arc-shaped base 2 to move synchronously. At this time, the damping limiter 605 located at the bottom of the arc-shaped base 2 moves synchronously with the arc-shaped base 2. During this process, the friction between the damping limiter 605 and the slide rail 1 can continuously counteract the vehicle's kinetic energy and inertia, effectively allowing the vehicle to stably stop within its maximum travel distance along the slide rail 1. The friction between the damping limiter 605 and the slide rail 1... The size can be adjusted to adapt to vehicles with different speeds. Specifically, the motor 603 drives the screw 604 to rotate. After the screw 604 rotates, it can simultaneously drive the two sets of moving plates 606 to move closer to each other. During this process, the spring 607 is continuously compressed. As the compression process progresses, the spring 607 continuously increases the elastic force it exerts on the damping limit frame 605. This elastic force is transmitted to the slide rail 1 through the damping limit frame 605, which increases the friction between the damping limit frame 605 and the slide rail 1, thereby effectively improving the loss and offsetting of vehicle kinetic energy and inertia.

[0028] In an optional embodiment of the invention, such as Figure 8 and Figure 9 As shown, the arc-shaped side plate 4 is equipped with a power generation mechanism 7 and an energy storage module 8. The power generation mechanism 7 and the energy storage module 8 are electrically connected. The translation component and the bidirectional drive component are both electrically connected to the energy storage module 8. The power generation mechanism 7 includes a rotating component and a kinetic energy generation component connected between the rotating component and the arc-shaped side plate 4. The rotating interceptor plate 3 is connected to the rotating component, and the kinetic energy generation component is electrically connected to the energy storage module 8.

[0029] The rotating assembly includes a rotating chamber 701 located inside the arc-shaped side plate 4, a drive shaft 703 movably connected to the arc-shaped side plate 4, a sector gear 704 connected to one end of the drive shaft 703, a rotating shaft 705 movably connected to the inner wall of the rotating chamber 701, and a gear 706 fixedly connected to the rotating shaft 705. The other end of the drive shaft 703 is detachably connected to the rotating interceptor plate 3.

[0030] The kinetic energy generation component includes several permanent magnet stators 702 fixedly connected to the inner wall of the rotating chamber 701, several annular conductive rings 708 disposed on the inner wall of the rotating chamber 701, and conductors 707 fixedly connected to the rotating shaft 705. The two ends of the conductors 707 are slidably connected to the corresponding annular conductive rings 708, and the several annular conductive rings 708 are all electrically connected to the energy storage module 8.

[0031] It should be noted that, in order to improve the overall stability of the equipment, an emergency power storage module 8 is installed inside. It is usually powered by pre-buried cables and mobile conductive rails for the translation component and bidirectional drive component. In the event of a power grid failure, the power storage module 8 can provide emergency power. At the same time, the kinetic energy of the rotating interceptor plate 3 can be converted into electrical energy for storage by the generator mechanism 7. The more vehicles pass in the same direction, the more electrical energy is converted by the generator mechanism 7. Specifically, when the rotating interceptor plate 3 is run over by a wheel and rotates, the rotating interceptor plate 3 can drive the drive shaft 703 to rotate. After the drive shaft 703 rotates, it can drive the sector gear 704 connected to it to rotate synchronously. When the sector gear 704 rotates, it can drive the gear 3 706 to rotate. After the gear 3 706 rotates, it can drive the conductor 707 connected to it to rotate. During the rotation of the conductor 707, electrical energy can be continuously generated and transferred to the power storage module 8 for storage through the annular conductive ring 708. The tooth structure of the sector gear 704 and the rotating shaft 705 can be ratchet-fitted. The sector gear 704 and the transmission shaft 703 can be elastically connected. That is, the sector gear 704 can rotate with the transmission shaft 703 and move radially along the transmission shaft 703. This allows the rotating shaft 705 to be continuously driven to rotate in the same direction during the reciprocating rotation of the rotating interceptor plate 3.

[0032] In an optional embodiment of the present invention, a highway safety anti-reverse driving system is also disclosed, which includes a highway safety anti-reverse driving device as described above, a plurality of speed measuring modules, a plurality of distance measuring modules, a plurality of image acquisition modules, and an integrated control box. The highway safety anti-reverse driving device, the plurality of speed measuring modules, the plurality of distance measuring modules, and the plurality of image acquisition modules are all electrically connected to the integrated control box. The plurality of speed measuring modules, distance measuring modules, and image acquisition modules are alternately arranged along the length of the highway. The speed measuring modules are used to acquire the speed data of the current reverse driving vehicle, the distance measuring modules are used to acquire the distance of the current reverse driving vehicle from the edge of the highway, and the image acquisition modules are used to acquire vehicle image data.

[0033] It should be noted that, as mentioned above, the speed of the vehicle currently traveling in the wrong direction can be obtained through the speed measurement module, and the distance between the vehicle and the edge of the road can be obtained through the distance measurement module. This allows the rotating interceptor 3 deployed in the corresponding lane to be raised at the corresponding angle. The image acquisition module can acquire the image data of the current vehicle. Combined with the currently acquired vehicle position, the wheel diameter data of the vehicle in the current image and the data of the vehicle chassis distance from the ground can be calculated. This information can then be converted into control signals through the integrated control box and the corresponding motors 603 and 510 can be controlled to work, thereby adjusting the rotation angle of the rotating interceptor 3 and the friction value between the damping limit bracket 605 and the slide rail 1.

[0034] The above description of this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.
