Description

Technical Field

[0001] The invention relates to the field of road maintenance safety equipment, and in particular to a heavy-duty anti-collision warning vehicle and an anti-collision buffer method. Background Art

[0002] During road maintenance operations, since adjacent lanes usually maintain normal traffic, maintenance personnel and equipment face the potential risk of being hit by passing vehicles. If passing vehicles accidentally enter the work area, it is very likely to cause a serious traffic accident, posing a serious threat to personnel safety. At present, commonly used safety measures include setting up road closure signs, traffic reflective cones, water barriers and other traffic guidance warning signs in front of the work area, and deploying anti-collision buffer vehicles. However, these measures still have certain limitations.

[0003] In the "A Rear Collision Warning System for Engineering Vehicles" disclosed in publication number CN218966801U, it includes a vehicle body, two support rods are fixedly installed at the bottom of the rear end of the vehicle body, and one end of the two support rods is fixedly installed with an anti-collision warning box. When the on-board millimeter-wave radar and the on-board visual ADAS detect that the target vehicle following behind the vehicle body is close to the vehicle body and meets the monitoring distance set by the on-board millimeter-wave radar and the on-board visual ADAS, the control module controls the sound and light alarm to start. Through the set sound and light alarm, it is convenient to issue sound and light to remind the following vehicle to attract the attention of the driver and passengers of the rear vehicle to avoid rear-end collisions as much as possible. The device can be installed behind engineering vehicles, road maintenance vehicles or other production and operation vehicles, and can effectively monitor the rear vehicles and determine whether they are likely to rear-end the vehicle, and send corresponding sound and light reminder information to the oncoming vehicles when a collision occurs or when the distance between the vehicles meets certain conditions, thereby increasing the safety of personnel. However, the above-mentioned anti-collision warning system requires a special vehicle as a basis, which not only increases the basic cost of normal operation and maintenance of the special vehicle, but also increases additional management and maintenance costs; and the existing anti-collision buffer vehicle is mainly designed to prevent the intrusion of small passenger vehicles, and the anti-collision capability for heavy vehicles such as large trucks is seriously insufficient. If a large truck loses control and breaks into the operation area, the existing anti-collision buffer vehicle may not be able to effectively stop it, thus causing a more serious secondary accident. Summary of the invention

[0004] In order to overcome the above-mentioned defects in the prior art, a heavy-duty anti-collision warning vehicle and an anti-collision buffering method are provided.

[0005] The technical solution of the present invention is as follows: a heavy-duty anti-collision warning vehicle, comprising an elastic energy-absorbing anti-collision panel, a partition-type energy-absorbing box, a friction energy-dissipating bottom plate, a mode-conversion driving component and a warning mechanism; the elastic energy-absorbing anti-collision panel is mounted on the front end of the partition-type energy-absorbing box; the partition-type energy-absorbing box is provided with a plurality of liquid partitions and cavity partitions for buffering energy absorption; the friction energy-dissipating bottom plate is fixed to the bottom of the partition-type energy-absorbing box; the mode-conversion driving component is mounted in a fixed cavity provided at the bottom of the partition-type energy-absorbing box, and the warning mechanism is mounted on the top of the partition-type energy-absorbing box.

[0006] Preferably, the mode conversion driving component includes an axle, tires and a hydraulic jacking mechanism; there are two tires, the two tires are connected by an axle, and the axle is equipped with a swing shaft for switching the working state of the tires; the hydraulic jacking mechanism is installed on the compartment type energy absorption box, which is used to lift the compartment type energy absorption box to facilitate the two tires to roll along the ground, thereby towing the anti-collision warning vehicle to move.

[0007] Preferably, the hydraulic lifting mechanism includes a motor, a hydraulic cylinder and a hydraulic support foot; the motor drives the hydraulic cylinder to perform a lifting movement, and the compartment-type energy absorption box is lifted up by the hydraulic support foot.

[0008] Preferably, a fixing hole for fixing the swing shaft is provided on the tire; the swing shaft can be inserted into or pulled out of the fixing hole on the tire to fix or unlock the tire.

[0009] Preferably, the compartment type energy absorption box includes a front steel plate, a rear steel plate, two side steel plates, a bottom steel plate, an internal transverse steel plate, an internal longitudinal steel plate and a top steel plate; the internal transverse steel plate and the internal longitudinal steel plate are assembled in the compartment type energy absorption box, dividing the inner cavity of the compartment type energy absorption box into staggered liquid compartments and cavity compartments. Preferably, the tops of the liquid compartments and the cavity compartments are both provided with a plurality of through holes; the plurality of through holes on the top of the liquid compartments are strip-shaped structures; the plurality of through holes on the top of the cavity compartments are circular structures.

[0010] Preferably, the elastic energy-absorbing anti-collision panel is a three-fold line structure and is assembled on the front steel plate.

[0011] Preferably, the friction energy dissipation bottom plate is a long strip of friction structure, which is evenly fixed to the bottom of the compartment-type energy absorption box.

[0012] Preferably, the warning mechanism includes a signal processor and a warning flashing light electrically connected to the signal processor, a large-scale electronic display screen, a directional tweeter and a camera; the camera is used to collect detection data and detect road conditions; the signal processor analyzes and processes the detection data, and sends a warning signal through the directional tweeter; the warning flashing light and the large-scale electronic display screen are assembled on the top of the compartment-type energy absorption box.

[0013] A collision avoidance and buffering method for a heavy-duty collision avoidance and warning vehicle comprises the following steps: S1. During road maintenance operations, the anti-collision warning vehicle is towed to the front of the operation area, the warning mechanism is activated, and the warning vehicle is converted from the towing state to the anti-collision working state, so that an anti-collision buffer zone is formed in front of the operation area; S2. When a small vehicle accidentally enters the collision buffer zone or loses control, it will hit the elastic energy-absorbing collision buffer panel. If the vehicle speed is low, the deformation of the elastic collision buffer panel and the compartment-type energy-absorbing box can stop the small vehicle. At this time, the elastic energy-absorbing collision buffer panel provides the first energy dissipation, and the deformation of the compartment-type energy-absorbing box provides the second energy dissipation. If the vehicle speed is high, in addition to the first and second energy dissipation, the friction energy dissipation bottom plate of the collision warning vehicle and the ground generate moving friction to provide the third energy dissipation. S3, when a large vehicle accidentally enters the anti-collision buffer zone or loses control, the first energy dissipation, the second energy dissipation and the third energy dissipation are consistent with step S2, and the friction force increased by the downward pressure applied by the large vehicle to the elastic anti-collision panel provides the fourth energy dissipation; during the collision stop process, the anti-collision warning vehicle will drive the large vehicle forward until it stops, and stop the large vehicle; S4. When the heavy-duty anti-collision warning vehicle finishes its work and needs to be transferred to another site, the compartment-type energy absorption box is lifted up by the hydraulic lifting mechanism of the mode conversion driving component, and the vehicle is switched to the towing state, and the heavy-duty anti-collision warning vehicle is towed away from the work site by a trailer.

[0014] Compared with the prior art, the present invention has the following beneficial effects: A heavy-duty anti-collision warning vehicle combines multiple energy dissipation mechanisms, effectively improving the safety of road maintenance work areas; through the combined design of elastic energy-absorbing anti-collision panels, compartment-type energy-absorbing boxes and friction energy-dissipating bottom plates, multi-level collision buffering is achieved, which can cope with the intrusion of vehicles of different speeds and weights; the setting of the early warning mechanism can send out early warning signals in time to remind drivers to pay attention and further reduce the risk of accidents.

[0015] Furthermore, the mode conversion driving component realizes the flexible conversion of the anti-collision warning vehicle between the working state and the towing state, thereby improving the adaptability and utilization efficiency of the vehicle; through the design of the hydraulic jacking mechanism, the vehicle can be easily jacked up, making it easier for the tires to roll along the ground, reducing the difficulty of towing; the design of the swing shaft allows the tires to be easily fixed or unlocked in different states, thereby enhancing the stability and safety of the vehicle.

[0016] Furthermore, the hydraulic lifting mechanism provides stable lifting power, ensuring that the compartment-type energy-absorbing box can be lifted safely and smoothly. The design of the motor-driven hydraulic cylinder realizes the automation and intelligence of the lifting action, reducing the difficulty of operation. The setting of the hydraulic support foot further enhances the stability and load-bearing capacity of the lifting mechanism.

[0017] Furthermore, the fixing holes and swing shafts on the tires enable quick fixing and unlocking of the tires, improving the flexibility and response speed of the vehicle. The design of the fixing holes and swing shafts allows the tires to be firmly fixed on the axles, preventing them from falling off or loosening during driving; it is easy to maintain and replace tires, reducing maintenance costs.

[0018] Furthermore, the compartment-type energy-absorbing box realizes a reasonable layout and efficient use of the interior of the energy-absorbing box through staggered liquid compartments and cavity compartments. The arrangement of internal transverse steel plates and internal longitudinal steel plates enhances the strength and stability of the energy-absorbing box and improves the collision buffering capacity.

[0019] Furthermore, the through holes on the top of the liquid compartment and the cavity compartment are helpful for drainage and ventilation, and the service life of the compartment type energy absorption box is increased. The through holes of the liquid compartment and the cavity compartment are of different shapes. Through the through hole design of the strip structure and the circular structure, the liquid compartment and the cavity compartment can absorb and disperse energy more effectively during a collision. The energy absorption efficiency and stability of the compartment type energy absorption box are improved, and the collision buffering capacity of the anti-collision warning vehicle is further enhanced.

[0020] Furthermore, the three-fold line shape can more effectively disperse the impact force during a collision. The front side steel plate is usually the front structure of a vehicle or building, which is the area most susceptible to collision impact. Installing the elastic energy-absorbing anti-collision panel here can significantly improve the overall structure's crash resistance and the buffering performance of the early warning vehicle. The fold line design of the elastic energy-absorbing anti-collision panel enables the anti-collision panel to better fit the front height of different models, taking into account both large and small models. The collision buffering capacity and stability of the anti-collision panel are improved, further ensuring the safety of maintenance workers.

[0021] Furthermore, the long strip friction structure design enables the friction energy dissipation base plate to better contact the ground, thereby improving friction; it enhances the stability of the anti-collision warning vehicle during a collision and helps to stop the intruding vehicle within a preset distance.

[0022] Furthermore, the early warning agency has realized real-time monitoring and early warning of road conditions, improving the intelligence level of anti-collision warning vehicles. The setting of warning flashing lights, large-scale electronic display screens and directional tweeters can intuitively remind drivers to pay attention and reduce the risk of accidents. The combination of cameras and signal processors enables early warning agencies to accurately collect and analyze data, improving the accuracy and timeliness of early warnings.

[0023] Furthermore, the anti-collision buffer method realizes the rapid and effective stopping of intruding vehicles through detailed steps and mechanisms; improves the safety and stability of the anti-collision warning vehicle, and protects the life and property of maintenance workers; realizes flexible response to different vehicle models and speeds, and improves the applicability and practicality of the anti-collision warning vehicle.

DETAILED DESCRIPTION

[0026] The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0027] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operate in a specific direction. Therefore, it should not be understood as a limitation of the present invention.

[0028] like Figures 1 to 6As shown, a heavy-duty anti-collision warning vehicle includes an elastic energy-absorbing anti-collision panel 1, a compartment-type energy-absorbing box 2, a friction energy-dissipating bottom plate 3, a mode-conversion driving component 4 and a warning mechanism 5; 5. The elastic energy-absorbing anti-collision panel 1 is mounted on the front end of the compartment-type energy-absorbing box 2, and the compartment-type energy-absorbing box 2 is provided with a plurality of compartments for buffering and absorbing energy, and the friction energy-dissipating bottom plate 3 is fixed to the bottom of the compartment-type energy-absorbing box 2; the mode-conversion driving component 4 is mounted in a fixed cavity 23 provided at the bottom of the compartment-type energy-absorbing box 2, which can be used for support in the anti-collision working state, and can also lift the compartment-type energy-absorbing box 2 for towing in the towing state; the warning mechanism 5 is mounted on the top of the compartment-type energy-absorbing box 2.

[0029] Furthermore, the plurality of compartments are composed of a plurality of liquid compartments 21 and a plurality of cavity compartments 22 arranged in an alternating manner; the liquid compartments 21 are filled with liquid, and the cavity compartments 22 are filled with air. The liquid compartments 21 and the cavity compartments 22 will deform in sequence when impacted, thereby gradually absorbing the impact energy and reducing the impact of the impact on the vehicle. The staggered arrangement can further improve the efficiency of energy absorption.

[0030] The elastic energy-absorbing anti-collision panel 1 is a three-fold line structure, designed to absorb and disperse the impact force during a collision. It is assembled at the front end of the compartment-type energy-absorbing box 2 as the first line of defense for the anti-collision warning vehicle.

[0031] The compartment-type energy-absorbing box 2 is a structure divided into multiple compartments, including staggered liquid compartments 21 and cavity compartments 22. The liquid compartments 21 can be filled with water or other liquids to increase the energy absorption effect. The cavity compartments 22 are used to balance the structure and provide additional energy absorption space. The front steel plate 201, the rear steel plate 202, the two side steel plates 203, the bottom steel plate 204, the top steel plate 207, the internal transverse steel plate 205 and the internal longitudinal steel plate 206 of the compartment-type energy-absorbing box 2 together constitute this solid structure.

[0032] Among them, the tops of the liquid compartment 21 and the cavity compartment 22 are both provided with a plurality of through holes 6; the plurality of through holes 6 provided on the top of the liquid compartment 21 are strip-shaped structures 61; the plurality of through holes 6 provided on the top of the cavity compartment 22 are circular structures 62. Under the same area, the through holes of the strip-shaped structure 61 can disperse stress more effectively than the through holes of the circular structure 62, thereby improving the structural strength of the liquid compartment, more effectively promoting the fluid exchange between the inside and outside of the liquid compartment 21, and helping to achieve more uniform energy distribution and absorption during a collision. The through holes of the circular structure 62 help to optimize the air circulation inside the cavity compartment 22, thereby providing an additional buffering effect during a collision; the through holes of the circular structure 62 are simpler in manufacturing process than the through holes of the strip-shaped structure 61, helping to reduce production costs and improve production efficiency. The strip-shaped structure 61 focuses more on improving fluid exchange and structural strength, while the circular structure 62 focuses more on air circulation and reducing stress concentration.

[0033] The friction energy dissipation bottom plate 3 is a long strip of friction structure, which is evenly fixed to the bottom of the compartment type energy absorption box 2. During the collision, it can consume energy through friction with the ground, providing additional anti-collision protection. In this embodiment, the friction structure is a rubber strip, and the friction structure is made of rubber material.

[0034] The mode conversion travel component 4 includes an axle 41, a tire 42 and a hydraulic jacking mechanism 43. The tire 42 is connected through the axle 41 and can be fixed or unlocked by the swing shaft 411. The hydraulic jacking mechanism 43 is composed of a motor, a hydraulic cylinder 432 and a hydraulic support foot 431, and is used to switch between the anti-collision working state and the towing state. When towing is required, the hydraulic jacking mechanism 43 can lift the compartment type energy absorption box 2, so that the tire 42 can rotate on the ground and drag the compartment type energy absorption box 2; when anti-collision is required, the hydraulic jacking mechanism 43 is retracted, and the friction energy dissipation bottom plate 3 at the bottom of the compartment type energy absorption box 2 contacts the ground, increasing the friction force and the contact area with the ground.

[0035] Among them, the tire 42 is provided with a fixing hole 421 for fixing the swing shaft 411; the swing shaft 411 can be inserted into or pulled out of the fixing hole 421 on the tire 42 to fix or unlock the tire 42; by simply inserting or pulling out the swing shaft 411 into the fixing hole 421 of the tire 42, the tire can be quickly switched from the anti-collision working state to the towing state. This design greatly simplifies the operation process and improves work efficiency; when the swing shaft 411 is inserted into the fixing hole 421 and fixed, the connection between the tire 42 and the axle 41 becomes firm and reliable, thereby ensuring the stability and safety of the anti-collision warning vehicle in the anti-collision working state. By adjusting the fixing state of the tire 42, the anti-collision warning vehicle can adapt to different road conditions and operation requirements. For example, in the anti-collision working state requiring high stability, the tire 42 can be firmly fixed on the axle 41; while in the towing state requiring flexible movement, the tire 42 can be unlocked and easily rotated.

[0036] The warning mechanism 5 includes a signal processor and a warning flashing light connected to the signal processor by electrical signals, a large-scale electronic display screen 51, a directional tweeter and a camera. The camera is used to collect detection data of road conditions, and the signal processor analyzes and processes the data and sends a warning signal through the directional tweeter. The warning flashing light and the large-scale electronic display screen 51 are installed on the top of the compartment-type energy absorption box 2 to visually warn passing vehicles.

[0037] Furthermore, the rear steel plate 202 is equipped with a center shaft 7, which, as an important supporting structure of the compartment-type energy-absorbing box 2, can enhance the structural strength of the entire box body. This helps to better absorb and disperse the impact force during a collision, and the center shaft 7 can provide stable support and traction performance for the vehicle, ensuring that the vehicle can remain stable in the anti-collision working state.

[0038] A collision avoidance and buffering method for a heavy-duty collision avoidance and warning vehicle comprises the following steps: S1. During road maintenance operations, the anti-collision warning vehicle is towed to the front of the operation area, the warning mechanism 5 is activated, and the warning vehicle is converted from the towing state to the anti-collision working state, so that an anti-collision buffer zone is formed in front of the operation area; S2. When a small vehicle accidentally enters the collision buffer zone or loses control, it will hit the elastic energy-absorbing collision-proof panel 1; if the vehicle speed is low, the deformation of the elastic collision-proof panel and the compartment-type energy-absorbing box 2 can stop the small vehicle. At this time, the elastic energy-absorbing collision-proof panel 1 provides the first energy dissipation, and the deformation of the compartment-type energy-absorbing box 2 provides the second energy dissipation; if the vehicle speed is high, in addition to the first and second energy dissipation, the friction energy dissipation bottom plate 3 of the collision warning vehicle and the ground generate moving friction to provide the third energy dissipation; S3, when a large vehicle accidentally enters the anti-collision buffer zone or loses control, the first energy dissipation, the second energy dissipation and the third energy dissipation are consistent with step S2, and the friction force increased by the downward pressure applied by the large vehicle to the elastic anti-collision panel provides the fourth energy dissipation; during the collision stop process, the anti-collision warning vehicle will drive the large vehicle forward until it stops, and stop the large vehicle; S4. When the heavy-duty anti-collision warning vehicle finishes its work and needs to be transferred to another site, the compartment-type energy absorption box 2 is lifted up by the hydraulic jacking mechanism 43 of the mode conversion travel component 4, and the vehicle is switched to the towing state, and the heavy-duty anti-collision warning vehicle is towed away from the work site by a trailer.

Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments.
