Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, specifically to an impact buffer end mechanism applied to motor vehicle lanes. Background Technology

[0002] Guardrails absorb collision energy by deforming the soil base, posts, beams, and endurance plates, and force out-of-control vehicles to change direction and return to their normal driving direction, preventing vehicles from running off the road, thus protecting vehicles and passengers and reducing losses caused by accidents.

[0003] For example, the Chinese patent with announcement number CN220746681U, entitled "(An Impact Buffer Guardrail)," includes: a first support plate, a second support plate, and a post. A set of first support plates is installed on the front of the post, and a set of second support plates is installed on the back of the post. Several first buffer pressure cylinders are installed on the front of the first support plate. This invention, through the arrangement of the first buffer pressure cylinders, the first buffer spring, and the buffer plate, can achieve a good buffering effect. Furthermore, the first buffer pressure cylinder can limit the rebound force of the first buffer spring. The buffer pad, the first buffer airbag, and the second buffer airbag can protect the vehicle's outer shell in the event of a minor collision. The buffer plate, the second buffer pressure cylinder, the second buffer spring, and the limiting plate further enhance the buffering effect, thus ensuring the buffering and protective effect of the impact buffer guardrail during use.

[0004] However, existing buffer guardrails used in motor vehicle lanes are rigidly connected during installation and use, which cannot weaken the impact force when a vehicle collides, thus causing significant damage. Therefore, they do not meet the current needs. In response, we have proposed an impact buffer end mechanism for motor vehicle lanes. Utility Model Content

[0005] The purpose of this utility model is to provide an impact buffer end mechanism for use in motor vehicle lanes, in order to solve the problem mentioned in the background art that the existing buffer guardrails used in motor vehicle lanes are all in rigid contact during installation and use, which cannot weaken the impact force when a vehicle collides, thus causing greater damage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an impact buffer end mechanism applied to a motor vehicle lane, comprising: an impact buffer guardrail body, a fixed base plate provided at the rear of the impact buffer guardrail body, and a wrapping sleeve provided between the fixed base plate and the impact buffer guardrail body, and four wrapping sleeves are provided.

[0007] Also includes:

[0008] The second embedded cavity is installed inside the front end face of the impact buffer guardrail body. There are two inner cavities above and below the second embedded cavity. A traction rotating roller is installed inside the second embedded cavity. Several traction rotating rollers are installed. Two reinforcing ends are installed at both ends of the several traction rotating rollers. The two reinforcing ends are installed inside the inner cavity respectively. The two reinforcing ends are rotatably connected to the traction rotating rollers through a central rotating shaft. A second weakening spring coil is provided on one side of each of the two reinforcing ends.

[0009] Preferably, the four packages are provided with hydraulic rods inside, one end of each hydraulic rod is provided with a telescopic rod, and one end of the telescopic rod extends through and into the interior of the hydraulic rod. A first weakening spring coil is provided around the telescopic rod and the hydraulic rod.

[0010] Preferably, the rear end face of the impact buffer guardrail is provided with a first embedded cavity on all four sides, and there are four first embedded cavities. One end of the telescopic rod is installed inside the first embedded cavity.

[0011] Preferably, a flexible sleeve is provided around the outer wall of each of the traction rotating rollers.

[0012] Preferably, a sealing mounting plate is provided on the end faces of the traction rotating rollers at both ends, and the sealing mounting plate is threadedly connected to the two ends of the traction rotating rollers by bolts, and a plurality of bolts are provided.

[0013] Preferably, the central rotating shaft is mounted on the end face of the sealing mounting plate and is fixedly connected.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model effectively disperses the impact force by rotating the traction roller through its central rotating shaft when a vehicle crashes into it out of control. Simultaneously, the inclusion of a second weakening spring coil, hydraulic rods, a first weakening spring coil, and telescopic rods maximizes the reduction of force when the vehicle impacts the guardrail. This protects the device and provides a buffer space for the vehicle, effectively avoiding the problem of existing buffer guardrails used in motor vehicle lanes, which are rigid in contact and unable to weaken the impact force during vehicle collisions, resulting in significant damage.

[0022] Example 1

[0023] Please see Figure 1-3 An embodiment of this utility model is provided: an impact buffer end mechanism applied to a motor vehicle lane, comprising: an impact buffer guardrail body 100, a fixed base plate 200 provided behind the impact buffer guardrail body 100, and a wrapping sleeve 300 provided between the fixed base plate 200 and the impact buffer guardrail body 100, and four wrapping sleeves 300 are provided.

[0024] Also includes:

[0025] The second embedded cavity 4001 is installed inside the front end face of the impact buffer guardrail body 100. There are two inner cavities 404 above and below the second embedded cavity 4001. A traction rotating roller 400 is installed inside the second embedded cavity 4001. There are several traction rotating rollers 400. Reinforcing ends 403 are provided at both ends of the several traction rotating rollers 400. There are two reinforcing ends 403. The two reinforcing ends 403 are installed inside the inner cavity 404 respectively. The two reinforcing ends 403 are rotatably connected to the traction rotating rollers 400 through the central rotating shaft 402. A second weakening spring coil 405 is provided on one side of each of the two reinforcing ends 403.

[0026] When a vehicle loses control and impacts the traction roller 400, the traction roller 400 can be rotated via the central rotating shaft 402, thereby effectively dispersing the impact force. At the same time, the second weakening spring coil 405, hydraulic rod 301, first weakening spring coil 302, and telescopic rod 303 are designed to maximize the weakening of the force when the vehicle impacts the guardrail, thus protecting the device and providing a buffer space for the vehicle.

[0027] Example 2

[0028] Please see Figure 2 The four sleeves 300 are equipped with hydraulic rods 301 inside. One end of the hydraulic rod 301 is equipped with a telescopic rod 303, and one end of the telescopic rod 303 passes through and extends into the interior of the hydraulic rod 301. A first weakening spring coil 302 is provided around the outside of the telescopic rod 303 and the hydraulic rod 301.

[0029] Please see Figure 2 The impact buffer guardrail body 100 has four first embedded cavities 101 inside its rear end face. One end of the telescopic rod 303 is installed inside the first embedded cavity 101.

[0030] Please see Figure 1 A flexible sleeve 401 is provided around the outer wall of several traction rotating rollers 400.

[0031] Please see Figure 3 A sealing mounting plate 406 is provided on the end face of several traction rotating rollers 400. The sealing mounting plate 406 is threadedly connected to both ends of the traction rotating rollers 400 by bolts 407, and several bolts 407 are provided.

[0032] Please see Figure 3 The central rotating shaft 402 is mounted on the end face of the sealing mounting plate 406 and is fixedly connected.

[0033] Working principle: In use, the fixed base plate 200 is fixedly connected to the installation position, so that the traction rotating roller 400 at the end face of the impact buffer guardrail body 100 acts inside the road. When a vehicle loses control and impacts the traction rotating roller 400, the traction rotating roller 400 can be rotated through the central rotating shaft 402 of the traction rotating roller 400, thereby effectively dispersing the impact force. At the same time, through the setting of the second weakening spring ring 405, hydraulic rod 301, first weakening spring ring 302 and telescopic rod 303, the force is weakened to the maximum extent when the vehicle impacts the guardrail, thereby protecting the device and providing a buffer space for the vehicle.
