Description

Technical Field

[0001] This invention belongs to the field of highway safety protection technology, specifically an integrated device for anti-collision buffering and early warning of highway curves. Background Technology

[0002] As key nodes in the road network, road curves are high-risk sections for traffic accidents due to factors such as obstructed visibility, significant changes in vehicle trajectory, and centrifugal force. In actual driving, some drivers have problems such as speeding and insufficient prediction of the curvature of curves. When vehicles pass through curves, they are prone to overturning or fishtailing due to excessive centrifugal force, or colliding with oncoming vehicles or roadside facilities due to blind spots. This not only causes vehicle damage and personal injury, but also leads to road congestion, seriously affecting the safety and efficiency of highway traffic.

[0003] In existing technologies, collision warning facilities for highway curves are mostly designed for a single function, either only installing collision protection structures such as crash barriers and corrugated guardrails, or only equipping warning devices such as speed warning signs and radar speed measurement prompts, resulting in poor collision warning effectiveness. Summary of the Invention

[0004] In view of the above situation and to overcome the shortcomings of the existing technology, the present invention provides an integrated device for collision avoidance buffering and early warning of highway curves, which effectively solves the problem of poor collision avoidance and early warning effect at present.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated device for anti-collision buffering and early warning of highway curves, including a base, an anti-collision buffering mechanism on the top of the base, and an early warning mechanism on the anti-collision buffering mechanism; The anti-collision buffer mechanism includes a vertical frame located above the base, which is perpendicular to the base. Multiple U-shaped rods are evenly spaced on the inner side of the vertical frame. Side blocks are fixedly connected to both ends of each U-shaped rod. A U-shaped frame is movably sleeved on the outer side of each U-shaped rod. Buffer springs are fixedly connected between each of the two side blocks and the U-shaped frame. Both buffer springs are sleeved on the outer side of the U-shaped rods. A force-bearing roller is fixedly connected to the inner side of the U-shaped frame. A rubber cylinder is fixedly sleeved on the outer side of the force-bearing roller.

[0006] Preferably, two reflective strips are symmetrically fixedly connected to the outer side of the force-bearing roller, and the rubber cylinder is located between the two reflective strips.

[0007] Preferably, a U-shaped round rod is fixedly connected to the outer side of the upright frame, and a movable plate is movably sleeved on the outer side of the U-shaped round rod, with the movable plate fixedly sleeved on the middle of the outer side of each U-shaped round rod.

[0008] Preferably, two sliders are symmetrically and movably sleeved on the outer side of the U-shaped round rod, and two movable rods are symmetrically and rotatably connected to the outer side of the movable plate. The ends of the two movable rods away from the movable plate are respectively rotatably connected to the outer side of the two sliders.

[0009] Preferably, a sleeve is fixedly sleeved on the outer middle of the U-shaped rod, the sleeve is located between the two sliders, and a buffer spring is fixedly connected between the two sliders and the sleeve, and the two buffer springs are sleeved on the outer side of the U-shaped rod.

[0010] Preferably, the warning mechanism includes a support frame fixed to the top of the base, a support shaft rotatably connected to the inner side of the support frame, a rotating plate fixedly sleeved on the outer middle of the support shaft, and a vertical frame fixed to the top of the rotating plate.

[0011] Preferably, two guide columns are symmetrically fixedly connected to the outer side of the support frame, a guide plate is movably sleeved between the two guide columns, a movable frame is rotatably connected to the top of the guide plate, and the top of the movable frame is rotatably connected to the outer side of the rotating plate.

[0012] Preferably, an L-shaped frame is fixedly installed on the top of the base, and an mounting plate is fixedly installed on the L-shaped frame. The ends of the two guide columns away from the support frame are fixedly connected to the mounting plate. Two buffer springs are symmetrically fixedly connected between the guide plate and the mounting plate, and the two buffer springs are respectively sleeved on the outside of the two guide columns.

[0013] Preferably, a PLC controller and a pressure sensor are fixedly installed on the side of the mounting plate near the support frame, a rubber column is fixedly connected to the side of the guide plate near the pressure sensor, the pressure sensor is electrically connected to the PLC controller, an alarm is fixedly installed on the top of the L-shaped frame, and the PLC controller is electrically connected to the alarm.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the rubber cylinder is directly impacted by a car and deforms, allowing the U-shaped frame to slide along the second U-shaped rod, facilitating the deformation of the first buffer spring. Simultaneously, the slider slides along the first U-shaped rod, facilitating the deformation of the second buffer spring. The rubber cylinder, the first buffer spring, and the second buffer spring can buffer the impact force through deformation, thereby improving the anti-collision effect through multi-stage buffering.

[0015] 2. This invention uses the force to rotate the upright frame, causing the guide plate to slide along the two guide posts, which facilitates the deformation of the two buffer springs. The buffer springs then achieve a buffering effect through deformation, thereby further improving the anti-collision effect.

[0016] 3. This invention uses the collision between the moving rubber column and the pressure sensor to activate the alarm via a PLC controller, which can warn oncoming vehicles and prevent secondary collisions. It also facilitates automatic alarm to highway management via remote communication technology. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Example 1, by Figures 1-6The present invention relates to an integrated device for anti-collision buffer and early warning of highway curves, including a base 1, an anti-collision buffer mechanism 2 on the top of the base 1, and an early warning mechanism 3 on the anti-collision buffer mechanism 2.

[0022] In Embodiment Two, based on Embodiment One, the anti-collision buffer mechanism 2 includes a vertical frame 201 located above the base 1. The vertical frame 201 is perpendicular to the base 1. Multiple U-shaped rods 206 are evenly spaced on the inner side of the vertical frame 201. Side blocks 209 are fixedly connected to both ends of each U-shaped rod 206. A U-shaped frame 207 is movably sleeved on the outer side of each U-shaped rod 206. Buffer springs 208 are fixedly connected between each side block 209 and the U-shaped frame 207. Spring 208 is sleeved on the outside of U-shaped rod 206. A force-receiving roller 205 is fixedly connected to the inside of the U-shaped frame 207. A rubber cylinder 202 is fixedly sleeved on the outside of the force-receiving roller 205. Two reflective strips 204 are symmetrically fixedly connected to the outside of the force-receiving roller 205. The rubber cylinder 202 is located between the two reflective strips 204. In scenarios with poor visibility, such as at night, in rain or fog, or when backlit on curves, when vehicle headlights illuminate the reflective strips 204, a high-brightness directional reflection occurs, resulting in a conspicuous reflection. The lighting effect continuously reminds the driver to slow down and drive cautiously, especially for large vehicles such as trucks and long-distance buses, effectively compensating for their large blind spots when turning. A U-shaped round rod 203 is fixedly connected to the outer side of the frame 201. A movable plate 2010 is movably sleeved on the outer side of the U-shaped round rod 203. The movable plate 2010 is fixedly sleeved on the outer middle of each U-shaped round rod 206. Two sliders 2011 are symmetrically movably sleeved on the outer side of the U-shaped round rod 203. The outer side of the movable plate 2010... Two movable rods 2012 are symmetrically rotated. The ends of the two movable rods 2012 away from the movable plate 2010 are respectively rotatably connected to the outside of the two sliders 2011. A sleeve 2013 is fixedly sleeved on the middle of the outer side of the U-shaped round rod 203. The sleeve 2013 is located between the two sliders 2011. A buffer spring 2014 is fixedly connected between the two sliders 2011 and the sleeve 2013. The two buffer springs 2014 are both sleeved on the outside of the U-shaped round rod 203. When a car collides with the rubber cylinder 202 in an accident, the rubber cylinder 202 deforms under the force. The force roller 205 drives the U-shaped frame 207 to slide along the second U-shaped rod 206, while the first buffer spring 208 is stretched. At the same time, the second U-shaped rod 206 drives the movable plate 2010 to slide along the first U-shaped rod 203, and the movable rod 2012 drives the slider 2011 to slide along the first U-shaped rod 203, while the second buffer spring 2014 is stretched. Thus, the rubber cylinder 202, the first buffer spring 208, and the second buffer spring 2014 buffer the impact force through deformation. Finally, the multi-stage buffering improves the anti-collision effect.

[0023] In embodiment three, based on embodiment one, the warning mechanism 3 includes a support frame 301 fixed to the top of the base 1. A support shaft 303 is rotatably connected to the inner side of the support frame 301. A rotating plate 302 is fixedly sleeved on the middle of the outer side of the support shaft 303. The upright frame 201 is fixed to the top of the rotating plate 302. Two guide posts 3013 are symmetrically fixedly connected to the outer side of the support frame 301. A guide plate 3012 is movably sleeved between the two guide posts 3013. The top of the guide plate 3012 is rotatably connected to... There is a movable frame 307, the top of which is rotatably connected to the outside of the rotating plate 302. An L-shaped frame 305 is fixedly installed on the top of the base 1, and an mounting plate 306 is fixedly installed on the L-shaped frame 305. The ends of the two guide columns 3013 away from the support frame 301 are fixedly connected to the mounting plate 306. Two buffer springs 308 are symmetrically fixedly connected between the guide plate 3012 and the mounting plate 306. The two buffer springs 308 are respectively sleeved on the outside of the two guide columns 3013. When the car collides with the rubber cylinder 202, it causes the upright frame 201 to move, which in turn causes the rotating plate 302 to rotate. The movable frame 307 drives the guide plate 3012 to slide along the two guide posts 3013. At this time, both buffer springs 308 are compressed, and the buffer springs 308 achieve the buffering effect again through deformation, which further improves the anti-collision effect.

[0024] In Example 4, based on Example 1, a PLC controller 309 and a pressure sensor 3010 are fixedly installed on the side of the mounting plate 306 near the support frame 301. A rubber column 3011 is fixedly connected to the side of the guide plate 3012 near the pressure sensor 3010. The pressure sensor 3010 is electrically connected to the PLC controller 309. An alarm 304 is fixedly installed on the top of the L-shaped frame 305. The PLC controller 309 is electrically connected to the alarm 304. When the guide plate 3012 slides along the two guide posts 3013, it drives the rubber post 3011 to move. When the rubber post 3011 comes into contact with the pressure sensor 3010, the pressure sensor 3010 transmits an electrical signal to the PLC controller 309. The PLC controller 309 controls the alarm 304 to start the alarm, warning subsequent vehicles to prevent secondary collisions. At the same time, it assists in locating the accident scene and finally automatically alarms the highway management through remote communication technology.
