Description

Technical Field

[0001] This invention relates to the field of traffic collision avoidance device technology, specifically a traffic collision avoidance device. Background Technology

[0002] With social development and rapid economic growth, the transportation industry has also experienced rapid growth. However, various safety hazards exist during transportation, especially in the event of emergencies, where vehicles are prone to colliding with guardrails. Currently, most guardrails on the market are made of steel, possessing high hardness and strength, effectively protecting pedestrians and vehicles from accidental injuries. However, in the event of a collision, guardrails can easily penetrate vehicles, causing irreversible damage to vehicles and personnel, resulting in significant economic losses.

[0003] Existing crash barrier structures are relatively simple, with their ends often exposed or featuring simple curved surfaces, failing to effectively buffer vehicle impacts. Therefore, it is essential to design a traffic crash barrier device that can cushion the impact force and reduce damage to vehicles when they collide with it. Summary of the Invention

[0004] To address the above problems, the present invention provides a traffic collision avoidance device.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a traffic collision avoidance device, including a guardrail and a buffer part, wherein a support column is connected to the bottom of the guardrail, and a buffer component is slidably connected inside the support column. The buffer part is disposed on the upper side of the guardrail, and the upper end of the buffer component is rotatably connected to the middle part of the buffer part. The front end of the buffer part is provided with a cylindrical buffer end, and the buffer end is located on the front side of the guardrail.

[0006] As an optimization, the width of the buffer end is greater than the width of the guardrail, the axis of the buffer end is vertically set, and the interior of the buffer end is provided with several horizontally set telescopic components, the length direction of the telescopic components being perpendicular to the length direction of the guardrail.

[0007] As an optimization, the guardrail includes two parallel guardrails, the inner side of which is provided with a sliding groove, and the support column is vertically arranged on the lower side of the guardrail. The buffer assembly has a connecting rod on its lower side, and a sliding rod at the lower end of the connecting rod, which is slidably connected to the sliding groove.

[0008] As an optimization, the buffer section includes two Y-shaped brackets arranged opposite each other, with buffer rods rotatably connected to both ends of the Y-shaped brackets. The outer ends of the buffer rods of the two Y-shaped brackets are hinged together, and a fixed column is connected to the rear end of the buffer assembly.

[0009] As an optimization, the support column has a vertical sliding cavity inside, and a sliding through hole at the top of the sliding cavity. A counterweight is slidably connected inside the sliding cavity, and a compression spring is provided between the counterweight and the bottom of the sliding cavity. Two pull ropes are connected to the upper part of the counterweight, and a fixing block is connected to the upper end of the pull ropes. The fixing block passes upward through the compression spring and the sliding through hole and is rotatably connected to the middle of the buffer part.

[0010] As an optimization, the outer side of the counterweight is in contact with the inner side of the sliding cavity, the top opening of the sliding cavity is smaller than the width of the counterweight, and the counterweight is coaxially arranged with the support column.

[0011] As an optimization, the buffer end is made of a tough material, and the telescopic component includes a telescopic cylinder, with both ends of the telescopic cylinder connected to the inner wall of the buffer end.

[0012] The beneficial effects of this solution are that a traffic collision avoidance device has the following advantages: A buffer section is connected to the upper side of the guardrail. The buffer section and the buffer end are used to buffer the impact of the vehicle. The buffer section is connected by a buffer assembly to strengthen the impact resistance of the buffer section, improve the buffering effect of the buffer section, and reduce the damage to the vehicle caused by the impact. When the buffer end is impacted, it deforms, increasing the impact surface and shielding the front of the guardrail from the vehicle, further reducing the damage to the vehicle and preventing the guardrail from penetrating it.

[0019] like Figure 1 As shown, a traffic collision avoidance device includes a guardrail and a buffer section. The bottom of the guardrail is connected to a support column 2, and a buffer component is slidably connected inside the support column 2. The buffer section is located on the upper side of the guardrail, and the upper end of the buffer component is rotatably connected to the middle of the buffer section. The front end of the buffer section is provided with a cylindrical buffer end 3, which is located on the front side of the guardrail.

[0020] The number of support columns 2 can be set to multiple. When the number of support columns 2 is 1, the upper end of the buffer assembly is connected to the middle of the buffer part.

[0021] like Figure 1 As shown, the width of the buffer end 3 is greater than the width of the guardrail. The axis of the buffer end 3 is vertically set. The buffer end 3 has a plurality of horizontally set telescopic components 4 inside. The length direction of the telescopic components 4 is perpendicular to the length direction of the guardrail.

[0022] The telescopic component 4 is evenly connected to the inside of the buffer end 3 from top to bottom. Before being impacted, the telescopic component 4 is in a shortened state, and the telescopic component 4 can buffer the deformation of the buffer end 3.

[0023] like Figure 1 As shown, the guardrail includes two parallel guardrails 1, the inner side of the guardrail 1 is provided with a sliding groove 6, and the support column 2 is vertically arranged on the lower side of the guardrail. The buffer assembly has a connecting rod 5 on its lower side, and a sliding rod at the lower end of the connecting rod 5. The sliding rod is slidably connected to the sliding groove 6.

[0024] The sliding rod is set perpendicular to the connecting rod 5. The sliding rod can be integrally formed with the connecting rod 5, or the sliding rod can be detachably connected to the connecting rod 5. The length of the sliding rod is greater than the interval between the two guardrails 1, and the sliding grooves 6 of the two guardrails 1 are open relative to each other.

[0025] like Figure 1 As shown, the buffer part includes two Y-shaped brackets 7 arranged opposite each other. The two ends of the Y-shaped brackets 7 are rotatably connected to buffer rods 8. The buffer rods 8 of the two Y-shaped brackets 7 are hinged together. The rear end of the buffer assembly is connected to a fixed column 9.

[0026] The two hinged buffer bars 8 are connected in a V-shape, with the connection ends of the two buffer bars 8 located on the outside of the guardrail. The lower end of the fixed post 9 can be damped and slidably connected to the guardrail 1, or it can be connected to the ground support with a damped and slidably connected assembly, so that the fixed post 9 can move accordingly when the buffer bars 8 are extended outward.

[0027] like Figure 4As shown, the support column 2 has a vertical sliding cavity 10 inside, and a sliding through hole at the top of the sliding cavity 10. A counterweight 11 is slidably connected inside the sliding cavity 10. A compression spring 12 is provided between the counterweight 11 and the bottom of the sliding cavity 10. Two pull ropes 13 are connected to the upper part of the counterweight 11. A fixing block 14 is connected to the upper end of the pull ropes 13. The fixing block 14 passes upward through the compression spring 12 and the sliding through hole and is rotatably connected to the middle of the buffer part.

[0028] When the buffer part deforms under force, the buffer rod 8 pulls the rope 13 to move upward, and the compression spring 12 squeezes the counterweight 11 to buffer the deformation force of the buffer part.

[0029] like Figure 4 As shown, the outer side of the counterweight 11 is in contact with the inner side of the sliding cavity 10, the top opening of the sliding cavity 10 is smaller than the width of the counterweight 11, and the counterweight 11 is coaxially arranged with the support column 2.

[0030] The buffer end 3 is made of a tough material, and the telescopic component 4 includes a telescopic cylinder, the two ends of which are connected to the inner wall of the buffer end 3.

[0031] The buffer end 3 can be made of materials such as steel, aluminum alloy, magnesium alloy, titanium alloy or copper alloy.

[0032] The operating principle of this device is as follows: When a transport vehicle collides with the buffer end 3, the buffer end 3 itself is tough and the telescopic component 4 is set up to initially buffer the impact of the vehicle. At the same time, the buffer end 3 deforms after being impacted, increasing the contact area between the buffer end 3 and the vehicle and reducing the pressure at the contact point between the vehicle and the buffer end 3. When the buffer end 3 is subjected to force, the Y-shaped bracket 7 connected to the buffer end 3 moves along the slide groove 6 after being subjected to force, so that the buffer rod 8 between the two Y-shaped brackets 7 is pushed outward to buffer the impact force. When the buffer bar 8 is extended outward, it pulls the rope 13 upward. Due to the damping connection between the counterweight 11 and the sliding cavity 10 and the setting of the compression spring 12, the force of the buffer bar 8 extending outward can be further buffered to prevent the guardrail 1 from penetrating the vehicle.

The patent protection scope of the present invention includes, but is not limited to, the product form and style of the above-described specific embodiments.
