[0027] The following is combined with Figure 1-7 This application is described in further detail.
[0028] The embodiment of the present application discloses a road traffic collision avoidance system. Figure 1 , including a plurality of columns 1 fixedly arranged at the side of the road, the columns 1 are grouped in pairs, and a plurality of anti-collision plates 2 are sequentially arranged between the two columns 1 in the same group.
[0029] Reference Figure 2 The anti-collision plate 2 includes a middle section 21, a first connecting section 22 and a second connecting section 23. The first connecting section 22 and the second connecting section 23 are respectively arranged on both sides of the column 1, and the first connecting section 22 and the second connecting section 23 are both provided with a second fixing piece 24 for fixing the middle section 21. The second fixing piece 24 includes a fixing bolt, and the first connecting section 22 and the second connecting section 23 are both fixed to the back side of the middle section 21 by fixing bolts; the first connecting section 22 and the second connecting section 23 are both located on the back side of the middle section 21. When the anti-collision plate 2 is hit by a vehicle, usually, the middle section 21 contacts the vehicle. Therefore, the probability of damage to the middle section 21 is relatively high. The anti-collision plate 2 is split into the middle section 21, the first connecting section 22 and the second connecting section 23. The middle section 21 can be removed and replaced by loosening the fixing bolts on the first connecting section 22 and the second connecting section 23, thereby increasing practicality.
[0030] Reference Figure 1 、 2When the anti-collision plate 2 is installed, the first connecting section 22 is located at the rear end of the vehicle in the direction of travel on the road, and the second connecting section 23 is located at the front end of the vehicle in the direction of travel on the road. A connecting frame 221 is fixedly provided on the first connecting section 22, and a connecting block 231 is hinged on the second connecting section 23. The connecting block 231 slides with the connecting frame 221 on the next level anti-collision plate 2, and a connecting groove 222 is opened on the connecting frame 221 in a direction perpendicular to the first connecting section 22. The connecting block 231 is slidably set in the connecting groove 222. The cross-section of the connecting block 231 is T-shaped, and the connecting groove 222 is adapted to the connecting block 231. During construction, the first connecting section 22 is provided on the anti-collision plate 2 close to the rear of the road, and the second connecting section 23 is not provided on the anti-collision plate 2 close to the front of the road.
[0031] Reference Figure 3 The second connecting section 23 is provided with a sliding groove 232 along the length direction of the middle section 21, and a slider 233 is slidingly arranged in the sliding groove 232. The cross-section of the slider 233 is T-shaped, and the sliding groove 232 is adapted to the slider 233. A receiving plate 234 is hinged on the slider 233, and the receiving plate 234 is hinged to the first connecting section 22 on the next-level anti-collision plate 2.
[0032] Reference Figure 4 、 5 The side wall of the column 1 is provided with a receiving groove 11, and a load-bearing rod 12 is slidably arranged in the receiving groove 11 along the length direction perpendicular to the column 1. The load-bearing rods 12 on the two columns 1 in the same group are parallel, and the sliding direction of the load-bearing rod 12 is perpendicular to the middle section 21. A limiting block is fixedly provided on the side wall of the load-bearing rod 12, and a limiting groove is provided on the side wall of the receiving groove 11 along the length direction of the load-bearing rod 12. The limit block is slidably arranged in the limit groove. A mounting block 13 is hinged on the load-bearing rod 12, and the rotation axis of the mounting block 13 is vertical. The mounting blocks 13 on the two columns 1 in the same group are fixed to the middle sections 21 on the anti-collision plates 2 on both sides by screws.
[0033] Reference Figure 5 A first elastic member 14 is provided on the column 1 for driving the load-bearing rod 12 to slide away from the column 1. The first elastic member 14 includes a first compression spring, which is arranged in the accommodating groove 11. One end of the first compression spring abuts against the side wall of the accommodating groove 11, and the other end of the first compression spring abuts against the load-bearing rod 12.
[0034] When a vehicle has an accident and collides with the anti-collision guardrail, the vehicle contacts one of the anti-collision plates 2. The anti-collision plate 2 that is collided is simultaneously subjected to the impact force in the direction perpendicular to the anti-collision plate 2 and in the direction of vehicle travel. The impact force in the direction perpendicular to the anti-collision plate 2 drives the anti-collision plate 2 to slide toward the column 1, and the anti-collision plate 2 offsets part of the impact force in the direction perpendicular to the anti-collision plate 2. During the sliding process of the anti-collision plate 2 that is collided, the connecting block 231 on the anti-collision plate 2 slides on the connecting frame 221 on the next level anti-collision plate 2, so that the anti-collision plate 2 at the collision position There is a certain misalignment between the collision plate 2 and the adjacent anti-collision plate 2 in front, so that when the vehicle continues to move forward along the anti-collision plate 2, it contacts the receiving plate 234, offsetting part of the impact force in the vehicle's forward direction. After that, the next level anti-collision plate 2 is also affected by the impact force of the vehicle and moves toward the column 1, and so on, thereby continuously weakening the impact force of the vehicle, to a certain extent preventing the vehicle from disintegrating, overturning or changing direction due to the huge impact load of the anti-collision plate 2 when colliding with the guardrail, so that the life safety of the people in the car can be effectively guaranteed.
[0035] Reference Figure 4 、 5 A fixing frame 3 is fixedly provided between the two columns 1 in the same group. Both sides of the fixing frame 3 are fixedly connected to the two columns 1 respectively. A plurality of push rods 31 are slidingly provided on the fixing frame 3 along the length direction of the load-bearing rod 12. The push rods 31 correspond to the anti-collision plate 2 one by one, and the length direction of the push rods 31 is parallel to the length direction of the load-bearing rod 12. A second elastic member 32 is provided on the fixing frame 3 for driving the push rods 31 to slide toward the anti-collision plate 2. The second elastic member 32 includes a second compression spring, and the second The compression spring is sleeved on the top rod 31, and a fixing plate 311 is fixedly provided on the side wall of the top rod 31. One end of the compression spring abuts against the fixing plate 311, and the other end of the compression spring abuts against the fixing frame 3. The top rod 31 abuts against the back side of the middle section 21 on the corresponding anti-collision plate 2; the top rod 31 is tightly pressed against the corresponding anti-collision plate 2 under the elastic force of the second compression spring, so that the anti-collision plate 2 always has a force moving away from the column 1, which is convenient for forming a dislocation between the two adjacent anti-collision plates 2 when the vehicle collides with the anti-collision plate 2.
[0036] Reference Figure 5 、 6 Each push rod 31 is provided with a slot 312, and the slots 312 of each push rod 31 are jointly engaged with the limit rod 33. In the embodiment of the present application, the slot 312 is provided at the bottom of the limit rod 33. In other embodiments, the slot 312 can be provided at the top of the push rod 31.
[0037] Reference Figure 6A buckle plate 34 is hinged on the fixing frame 3, and a first fixing part 35 for fixing the buckle plate 34 is provided on the fixing frame 3. The first fixing part 35 includes a limiting bolt, and a through hole for the limiting bolt to pass through is provided on the buckle plate 34. A threaded hole adapted to the limiting bolt is provided on the fixing frame 3. A receiving groove 341 for the limiting rod 33 to enter is provided on the buckle plate 34. When the buckle plate 34 is used to prevent the limiting rod 33 from being disengaged from the slot 312 of the top rod 31 when it is idle.
[0038] Reference Figure 6 The fixing frame 3 is provided with an ejector for ejecting the limiting rod 33 from the slot 312 of each ejector rod 31. The ejector includes a ejector block 36. The ejector block 36 is fixedly set on the fixing frame 3. A guide inclined surface 361 is provided at one end of the ejector block 36 close to the anti-collision plate 2. The guide inclined surface 361 gradually tilts downward in the direction away from the anti-collision plate 2.
[0039] When the anti-collision plate 2 is subjected to the impact force of the vehicle, the impact force of the vehicle is weakened directly by the first compression spring on the column 1 and the second compression spring on the fixing frame 3, thereby ensuring the life safety of the occupants of the vehicle and reducing the damage to the vehicle; when the anti-collision plate 2 is subjected to the impact force of the vehicle, the limiting rod 33 slides a certain distance, and the limiting rod 33 is located above the receiving groove 341 on the buckle plate 34 and contacts the top block 36. The guide pushes the limit rod 33 out of the card slot 312 of each push rod 31 and falls into the receiving groove 341. At this time, the anti-collision plate 2 in front of the collision position slides away from the column 1 under the action of the second compression spring and the push rod 31, thereby weakening the subsequent impact force of the vehicle. In the process of the vehicle impact force pushing the anti-collision plate 2 to slide toward the column 1, part of the impact force of the vehicle is weakened by the second compression spring, thereby improving the weakening effect of the vehicle impact force, and through the setting of the limit rod 33 and each push rod 31 on the fixing frame 3, the stability of the anti-collision plate 2 when idle is effectively increased.
[0040] Reference Figure 5 、 6 The cross section of the limit rod 33 is circular. By setting the cross section of the limit rod 33 to be circular, when the top block 36 pushes the limit rod 33 out of the slot 312 of the push rod 31, the contact area between the limit rod 33 and the guide inclined surface 361 on the top block 36, as well as between the limit rod 33 and the side wall of the slot 312 is reduced. In addition to relative sliding between the limit rod 33 and the guide inclined surface 361 or the side wall of the slot 312, there is also a certain rolling, which facilitates the ejection of the limit rod 33 from the slot 312 of the push rod 31.
[0041] Reference Figure 4 、 7, a plurality of guide posts 37 are slidably provided on the fixing frame 3, and the length direction of the guide posts 37 is parallel to the length direction of the push rod 31. A baffle 38 is fixedly provided on each guide post 37, and each baffle 38 is located below the anti-collision plate 2. The cross section of the baffle 38 is arc-shaped, and the two sides of the baffle 38 are flipped toward the fixing frame 3. An anti-slip block 371 is fixedly provided at one end of the guide post 37 away from the baffle 38, and a third elastic member 39 is provided on the fixing frame 3 for driving the baffle 38 to slide away from the fixing frame 3. The elastic member 39 includes a third compression spring, which is sleeved on the guide column 37. One end of the third compression spring abuts against the fixing frame 3, and the other end of the third compression spring abuts against the baffle 38. The baffle 38 increases the protection range of the vehicle and improves the protection effect. When the vehicle has an accident, the vehicle is always in contact with the baffle 38. The impact force of the vehicle is weakened by the third compression spring and the baffle 38, and a certain reverse impact force is formed on the lower plate of the vehicle by the baffle 38 and the third compression spring, further reducing the possibility of the vehicle rolling over.
[0042] The implementation principle of a road traffic collision avoidance system in an embodiment of the present application is as follows: when a vehicle has an accident and collides with a collision guardrail, the vehicle contacts one of the collision plates 2, and the collided collision plate 2 is simultaneously subjected to the impact force of the vehicle in the direction perpendicular to the collision plate 2 and along the direction of vehicle travel. Under the influence of the limiting rod 33, the impact force in the direction perpendicular to the collision plate 2 drives each collision plate 2 to slide together toward the column 1. When the impact force of the vehicle is small, the impact force of the vehicle is directly weakened by the first compression spring on the column 1 and the second compression spring on the fixing frame 3, thereby ensuring the life safety of the people in the vehicle and reducing damage to the vehicle.
[0043] When the impact plate 2 is subjected to a greater impact force from the vehicle, after the limiting rod 33 slides a certain distance, the limiting rod 33 is located above the receiving groove 341 on the buckle plate 34 and contacts the top block 36. The limiting rod 33 is pushed out of the slot 312 of each push rod 31 through the guidance of the guide slope 361 on the top block 36 and falls into the receiving groove 341. At this time, the impact plate 2 in front of the impact position slides away from the column 1 again under the action of the second compression spring and the push rod 31, and the connecting block 231 on the impact plate 2 at the impact position is on the connecting frame 221 on the next level impact plate 2. The sliding causes a certain misalignment between the anti-collision plate 2 at the collision position and the adjacent anti-collision plate 2 in front, so that when the vehicle continues to move forward along the anti-collision plate 2, a part of the impact force in the vehicle's forward direction is offset. Then, the next level anti-collision plate 2 is also affected by the impact force of the vehicle and moves toward the direction close to the column 1. And so on, thereby continuously weakening the impact force of the vehicle, to a certain extent preventing the vehicle from disintegrating, overturning or changing direction due to the huge impact load of the anti-collision plate 2 when colliding with the guardrail, so that the life safety of the people in the car can be effectively guaranteed.
[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
