[0001] This invention relates to the field of industrial automation technology, and in particular to a crash barrier that is easy to maintain. Background Technology

[0002] With the rapid development of science and technology and the continuous improvement of people's living standards, more and more people own private cars, resulting in a surge in vehicles on the road. This increased number of vehicles brings more safety hazards, primarily manifested in traffic accidents. To ensure road safety, guardrails are typically installed on both sides of the road. These guardrails delineate road boundaries and, to some extent, prevent vehicles from crossing them, especially when the road is flanked by rivers or canyons.

[0003] Existing guardrails, designed for isolation, are made of rigid metal materials and are generally fixed structures. However, collisions between vehicles, whether traveling at high speeds or slowly, and the guardrails themselves can be damaged. The guardrails themselves are also easily deformed and rendered unusable upon impact. Therefore, this invention proposes an anti-collision guardrail to solve the problems existing in the prior art.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figures 1-2This is the first embodiment of the present invention, which provides a crash barrier that is easy to maintain. In order to address the safety hazards caused by high-speed driving of existing vehicles, the present invention designs a crash barrier. It includes an interception component 100, which includes a blocking member 101, a buffer block 102 disposed on the outer wall of the blocking member 101, reinforcing bars 103 disposed on both sides of the blocking member 101, and a buffer member 104 disposed on the outer wall of the blocking member 101.

[0030] In this embodiment, the barrier 101 is a three-dimensional column. A buffer block 102 is detachably installed on the outer surface of the barrier 101. The buffer blocks 102 are bolted together between two three-dimensional barrier 101. When a car is hit from the side, the impact force of the car can be released to the other buffer blocks 102 through the connection between the buffer blocks 102, thereby achieving the effect of the barrier 101 dissipating the impact force of the car. Reinforcing rods 103 are installed on both sides of the outer wall of the barrier 101. The other end of the reinforcing rod 103 is fixedly connected to the ground, thereby enhancing the stability of the crash barrier.

[0031] Buffer blocks 102 are installed above and below the buffer member 104. A buffer member 104 is rotatably provided on the outer wall of the barrier member 101. In this embodiment, the buffer member 104 is a cylinder. When a car hits the barrier member 101 from the side, it will first contact the cylindrical buffer member 104. The buffer member 104 will rotate, allowing the car to slide off the surface of the cylinder and guide the car to the next buffer member 104. The next buffer member 104 starts to roll, thereby dissipating the force on the car, reducing the possibility of the car breaking the barrier member 101, reducing the risk of car collision, and thus improving the safety of the people in the car.

[0032] Example 2

[0033] Reference Figures 1-4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that, in order to further improve the service life of the crash barrier, the barrier 101 in this embodiment includes a first intercepting rod 101a and a second intercepting rod 101b. The first intercepting rod 101a is provided with a connecting post 101c inside, and the second intercepting rod 101b is provided with a mounting post 101d on its outer wall.

[0034] The blocking component 101 consists of a first blocking rod 101a and a second blocking rod 101b. A connecting post 101c is fixedly installed at one end of the first blocking rod 101a near the second blocking rod 101b, and the second blocking rod 101b is sleeved on the outer wall of the connecting post 101c, thus connecting the first blocking rod 101a and the second blocking rod 101b. The second blocking rod 101b is rotatably connected to one end of the mounting post 101d near the first blocking rod 101a, and the second blocking rod 101b is positioned within the first blocking rod. Between the interceptor bar 101a and the mounting post 101d, the advantage of this design is that it divides the crash barrier into four parts. The first interceptor bar 101a and the second interceptor bar 101b are connected by the connecting post 101c. If an impact occurs, it will first impact the surface of the buffer 104. If the buffer 104 is deformed by the impact, the upper and lower ends of the buffer 104 will move, and at the same time, the force will be applied to the first interceptor bar 101a and the second interceptor bar 101b respectively, thereby reducing the impact force from acting directly on the connecting post 101c.

[0035] The outer wall of the first intercepting rod 101a is provided with a first rotating shaft 101a-1, and the reinforcing rod 103 is rotatably disposed on the outer wall of the first rotating shaft 101a-1.

[0036] In this design, a first rotating shaft 101a-1 is symmetrically mounted on the outer wall of the end of the first intercepting rod 101a away from the second intercepting rod 101b. Each first rotating shaft 101a-1 has a reinforcing rod 103 rotatably mounted on its outer wall, with the other end of the reinforcing rod 103 slidably connected. When the blocking member 101 is impacted by a certain force, the second intercepting rod 101b rotates, driving the first intercepting rod 101a to rotate via the connecting post 101c. The first intercepting rod 101a then pushes the reinforcing rod 103 to slide. When the other end of the reinforcing rod 103 slides to a certain distance, the reinforcing rod 103 supports the first intercepting rod 101a, supporting the blocking member 101. The entire blocking member 101 and the buffer block 102 on the outer wall of the blocking member 101 form a slope. The tire travels along the slope, reducing kinetic energy. When the tire travels over the slope, the tire falls off the slope, and the buffer block 102 and the buffer member 104 begin to contact the bottom of the car, suspending the front part of the car in the air, causing the car to stop and providing a second protection for the car.

[0037] The second interceptor bar 101b has a second rotating shaft 101b-1 on its outer wall and a first sliding groove 101b-2 inside its interior. The mounting post 101d has a movable space 101d-1 on its end face. The mounting post 101d rotates on the outer wall of the second rotating shaft 101b-1 and has a second sliding groove 101d-2 inside its interior. The connecting post 101c passes through the first sliding groove 101b-2.

[0038] The mounting post 101d has a movable space 101d-1 at one end near the second interceptor bar 101b. This movable space 101d-1 is equivalent to a rectangular space carved out on the upper surface of the cylinder, and the width of the rectangular space is smaller than the diameter of the cylinder. One end of the second interceptor bar 101b is installed inside the rectangular space, and a second rotating shaft 101b-1 is fixedly connected to the outer wall of this end. The second rotating shaft 101b-1 extends through the mounting post 101d to the outside, realizing the rotatable installation of the second interceptor bar 101b and the mounting post 101d. The second sliding groove 101d-2 runs through the top and bottom of the mounting post 101d. At the end, the connecting post 101c passes through the first slide groove 101b-2 and extends into a part of the interior of the second slide groove 101d-2 to ensure the rigidity of the barrier 101. When the buffer 104 is deformed by impact, the first intercepting rod 101b begins to move upward, which in turn drives the connecting post 101c to move upward. The connecting post 101c leaves the second slide groove 101d-2, and the second intercepting rod 101b rotates, which then pushes the reinforcing rod 103 to slide, achieving a ramp effect. This achieves multiple buffering and multiple protection effects, maximizing the safety of the car after a collision.

[0039] The buffer 104 includes a bearing 104a with an outer wall of a blocking member 101, and a rotating plate 104b is movably connected to the outer wall of the bearing 104a. The rotating plate 104b is an arc plate.

[0040] To better achieve the buffering effect and the overall function of the device, bearings 104a are fixedly connected to the outer walls of the first intercepting rod 101a and the second intercepting rod 101b. Then, the rotating plate 104b is connected to the bearings to reduce the friction between the rotating plate 104b and the blocking member 101, so that the rotation is smooth and the buffer member 104 will not get stuck when cutting in from the side. The rotating plate 104b is an arc-shaped plate to facilitate the direction of the guiding force.

[0041] The outer walls of the first intercepting rod 101a and the second intercepting rod 101b are both fixedly connected to bearings 104a. The outer wall of the bearings 104a is provided with an array of first sliders 104a-1. The outer wall of the first sliders 104a-1 is rotatably provided with a first connecting rod 104c. The other end of the first connecting rod 104c is rotatably connected to the inner wall of the rotating plate 104b.

[0042] Each bearing 104a has a first slider 104a-1 mounted in an array on its outer wall. The outer wall of the first slider 104a-1 is rotatably connected to a first connecting rod 104c. The end of the first connecting rod 104c away from the first slider 104a-1 is rotatably connected to the inner wall of the rotating plate 104b. The distance between the ends of the first connecting rods 104c on the outer walls of the two bearings 104a and the ends of the rotating plate 104b is shorter than the distance between the bearings 104a. This design ensures that when the rotating plate 104b is impacted, both ends of the first connecting rod 104c tend to move towards each other. Since the second intercepting rod 101b is restricted, the first intercepting rod 101a will move upward, ensuring that the connecting post 101c moves upward. This ensures that after deformation, the connecting post 101c can detach from the mounting post 101d and rotate.

[0043] The array of rotating plates 104b includes multiple plates, and the rotating plates 104b can form a cylinder; the cylinder formed by the rotating plates 104b can rotate around the outer wall of the barrier 101.

[0044] The rotating plate 104b is divided into multiple parts, which can be attached to form a cylindrical shape, thereby enabling the buffer 104 to rotate around the blocking member 101.

[0045] A first elastic element 104d is connected between the first connecting rod 104c on the outer wall of the two bearings 104a.

[0046] The first elastic element 104d is a compression spring. One end of the first elastic element 104d is fixedly connected to the outer wall of the first connecting rod 104c on the outer wall of the first intercepting rod 101a, and the other end is fixedly connected to the outer wall of the first connecting rod 104c on the outer wall of the second intercepting rod 101b. When the impact force of the car hits the rotating plate 104b, the rotating plate 104b will simultaneously compress the corresponding first connecting rod 104c. At this time, the first elastic element 104d will be pulled, giving the car a buffer space and preventing it from directly hitting the hard shell. Subsequently, due to the side impact of the car, the rotating plate 104b that was hit will rotate. Then, the next rotating plate 104b will contact the car body and be compressed, and then continue to rotate, and so on. If the impact force is not enough to stretch the spring to the point that it causes the connecting post 101c inside the first intercepting rod 101a to disengage from the second slide groove 101, the impact force will be reduced. d-2, if the rigid connection between the second interceptor bar 101b and the mounting post 101d is released, the car will be guided by the buffer 104 to move along the direction in which the crash barrier is installed. However, if a car crashes or makes a straight-line collision, the crash barrier may break directly. Subsequently, a protruding post may form at the bottom of the crash barrier, causing secondary damage to the vehicle and failing to intercept the vehicle, which may continue to crash. At this time, when the impact force is sufficient to pull the first elastic member 104d, the blocking member 101 will unlock, allowing the second interceptor bar 101b to rotate and turning the blocking member 101 into a ramp. The main purpose is to buffer a certain amount of the car's momentum, and at the same time, raising it is to slow down the car. Raising a ramp platform allows the front wheels of the car to be suspended in the air, allowing the car chassis to generate friction with the ground and stop the car. It should be noted that the installation distance between the two easily maintainable crash barriers should be less than the width of the car; at the same time, the buffer block 102 can be made of a tough material, such as an airbag; and in this solution, the buffer blocks 102 are no longer connected together.

[0047] In summary, when a car collides with the guardrail at an angle, the buffer 104 guides the car along the installation trajectory of the guardrail, preventing the car from directly breaking through the guardrail and causing danger; it also reduces the damage to the car from the guardrail. When the car hits the guardrail directly, the blocking component 101 deflects, lifting the car's chassis and further stopping the car's movement. Another advantage of this design is that the impact is contained within a small area, minimizing the impact on the surrounding area; even if there is subsequent damage, repairs will be minimal.

[0048] Example 3

[0049] Reference Figures 1-6 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that, in order to enhance the strength of the overall device and ensure that the car that crashes into the barrier 101 is intercepted, the mounting part 200 is installed behind the barrier 101.

[0050] Preferably, the other end of the reinforcing rod 103 away from the blocking member 101 is connected to a mounting member 200. The mounting member 200 includes a mounting platform 201, and the end face of the mounting platform 201 is provided with an abutment plate 202, which is connected to the reinforcing rod 103.

[0051] The mounting platform 201 is fixedly connected to the rear of the barrier 101. The upper surface of the mounting platform is detachably equipped with an abutment plate 202, which can be easily removed using bolts or similar means.

[0052] Preferably, the surface of the contact plate 202 is provided with a third sliding groove 202a, and the inner wall of the third sliding groove 202a is provided with a groove 202a-1;

[0053] Two reinforcing rods 103 are provided with rollers 203 that can slide along the third groove 202a at the ends away from the blocking member 101, and the outer wall of the rollers 203 is provided with limiting blocks 203a.

[0054] The third slide groove 202a penetrates the contact plate 202 and is a transverse slide groove. Reinforcing rods 103 are fixedly connected to both ends of the roller 203, which slides within the third slide groove 202a. A groove 202a-1 is provided at one end of the third slide groove 202a near the blocking member 101. Correspondingly, a limiting block 203a is provided on the outer wall of the roller 203. During installation, the limiting block 203a engages with the groove 202a-1. Inside, the limiting block 203a abuts against the inner wall of the groove 202a-1. When the first blocking rod 101a in the blocking member 101 moves upward, the roller 203 moves a distance in the direction of the blocking member 101, and at the same time drives the limiting block 203a to rotate a certain angle. Then the second blocking rod 101b starts to rotate, pushing the reinforcing rod 103 to move. When it moves to the end of the third slide groove 202a, the slope of the blocking member 101 is formed, which protects the car.

[0055] The advantage of mounting component 200 is that while restricting the rotation of the barrier component 101, it can also switch between the reinforcement and support effects of the reinforcing rod 103. When the barrier component 101 is not rotating, it provides reinforcement and support for the barrier component. When the barrier component 101 rotates, the reinforcing rod 103 provides support.
