Description

Technical Field

[0001] The utility model relates to the field of road maintenance safety equipment, in particular to a heavy-duty anti-collision warning vehicle. Background Art

[0002] During road maintenance operations, adjacent lanes typically remain open to traffic, placing maintenance personnel and equipment at risk of being struck by passing vehicles. If a passing vehicle inadvertently enters the work area, it could potentially cause a serious traffic accident, posing a serious threat to personnel safety. Currently, common safety measures include placing road closure signs, traffic cones, water barriers, and other traffic guidance and warning signs in front of the work area, as well as deploying collision avoidance vehicles. However, these measures still have limitations.

[0003] In the "A Rear Collision Warning System for Engineering Vehicles" disclosed with 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 each of the support rods is fixedly installed with a 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. The sound and light alarm is set to emit 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. It can effectively monitor oncoming vehicles and determine whether they may rear-end the vehicle, and send corresponding sound and light reminder information to the oncoming vehicle in the event of a collision or when the distance between vehicles meets certain conditions, thereby increasing the safety of personnel. However, the aforementioned collision avoidance warning system requires a dedicated vehicle as its foundation. This not only increases the basic costs of operating and maintaining the dedicated vehicle, but also adds additional management and maintenance costs. Furthermore, existing collision avoidance vehicles are primarily designed to protect against small passenger vehicles and are severely inadequate for heavy vehicles like trucks. If a large truck were to lose control and enter the work area, existing collision avoidance vehicles might not be able to effectively stop it, potentially leading to a more serious secondary accident.

[0008] Preferably, the hydraulic jacking mechanism includes a motor, a hydraulic cylinder and a hydraulic support foot; the motor drives the hydraulic cylinder to perform a jacking movement, and the compartment-type energy absorption box is lifted up by the hydraulic support foot.

[0009] 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.

[0010] Preferably, the partition 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 partition type energy absorption box, dividing the partition type energy absorption box into a liquid partition and a cavity partition.

[0011] Preferably, the tops of the liquid compartment and the cavity compartment are both provided with a plurality of through holes; the plurality of through holes provided on the top of the liquid compartment are strip-shaped; the plurality of through holes provided on the top of the cavity compartment are circular.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 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 vehicles of different speeds and weights; the setting of the early warning mechanism can issue early warning signals in a timely manner to alert drivers and further reduce the risk of accidents.

[0017] Furthermore, the compartments within the compartment-type crash tank, including liquid-filled compartments and air-filled compartments, are staggered to further enhance energy absorption efficiency. The liquid and air compartments deform upon impact, absorbing the impact energy and mitigating the impact on the vehicle.

[0018] Furthermore, the mode conversion driving component enables the anti-collision warning vehicle to flexibly switch between the working state and the towing state, improving the adaptability and utilization efficiency of the vehicle; through the design of the hydraulic jacking mechanism, the vehicle can be easily jacked up, facilitating the tires to roll along the ground, reducing the difficulty of towing; the swing axis design allows the tires to be easily fixed or unlocked in different states, enhancing the stability and safety of the vehicle.

[0019] Furthermore, the hydraulic jacking mechanism provides stable lifting power, ensuring the compartment-type energy-absorbing box can be lifted safely and smoothly. The motor-driven hydraulic cylinder design realizes automated and intelligent lifting action, reducing operational difficulty. The provision of hydraulic support feet further enhances the stability and load-bearing capacity of the jacking mechanism.

[0020] Furthermore, the tire's fixing holes and swing axis allow for quick tire fixation and unlocking, improving the vehicle's agility and responsiveness. The design of the fixing holes and swing axis securely fasten the tire to the axle, preventing it from falling off or loosening during driving. This also facilitates tire maintenance and replacement, reducing maintenance costs.

[0021] Furthermore, the compartmentalized crash box achieves a rational layout and efficient utilization of the interior through the staggered arrangement of liquid compartments and cavity compartments. The internal transverse and longitudinal steel plates enhance the strength and stability of the crash box, improving its collision-absorbing capacity.

[0022] Furthermore, the through-holes on the tops of the liquid and cavity compartments facilitate drainage and ventilation, extending the lifespan of the energy-absorbing box. The through-holes in the liquid and cavity compartments have different shapes. The strip-shaped and circular through-hole designs allow the liquid and cavity compartments to more effectively absorb and disperse energy during a collision. This improves the energy absorption efficiency and stability of the energy-absorbing box, further enhancing the collision mitigation capabilities of the anti-collision warning vehicle.

[0023] Furthermore, the triangular folding line design more effectively disperses the impact force during a collision. The front steel plate is typically the front structure of a vehicle or building, which is most vulnerable to collision impact. Installing the elastic energy-absorbing anti-collision panel here significantly improves the overall structure's crashworthiness and the vehicle's cushioning performance. The panel's folding line design allows it to better conform to the front height of different vehicle models, accommodating both large and small vehicles. This improves the panel's impact-absorbing capacity and stability, further ensuring the safety of maintenance workers.

[0024] Furthermore, the long 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.

[0025] Furthermore, early warning agencies have achieved real-time monitoring and early warning of road conditions, enhancing the intelligence of collision warning vehicles. Warning flashing lights, large electronic displays, and directional tweeters intuitively alert drivers and reduce accident risks. The combination of cameras and signal processors enables early warning agencies to accurately collect and analyze data, improving the accuracy and timeliness of warnings.

DETAILED DESCRIPTION

[0036] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0037] 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 device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0038] like Figures 1 to 6As shown, a heavy-duty anti-collision warning vehicle includes an elastic energy-absorbing anti-collision panel 1, a partition-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 assembled at the front end of the partition-type energy-absorbing box 2, and the inner cavity of the partition-type energy-absorbing box 2 is provided with a plurality of partitions for buffering energy absorption, and the friction energy-dissipating bottom plate 3 is fixed to the bottom of the partition-type energy-absorbing box 2; the mode-conversion driving component 4 is assembled in a fixed cavity 23 provided at the bottom of the partition-type energy-absorbing box 2, which can be used for support in the anti-collision working state, and can also lift the partition-type energy-absorbing box 2 for towing in the towing state; the warning mechanism 5 is assembled at the top of the partition-type energy-absorbing box 2.

[0039] 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.

[0040] The elastic energy-absorbing anti-collision panel 1 is a three-fold structure designed to absorb and disperse the impact force during a collision. It is installed at the front end of the compartment-type energy-absorbing box 2 as the first line of defense for the anti-collision warning vehicle.

[0041] The compartment-type energy absorption 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, rear steel plate 202, side steel plates 203, bottom steel plate 204, top steel plate 207, internal transverse steel plate 205, and internal longitudinal steel plate 206 of the compartment-type energy absorption box 2 together form this sturdy structure.

[0042] The top of the liquid compartment 21 and the cavity compartment 22 is provided with a plurality of through holes 6; the plurality of through holes 6 provided on the top of the liquid compartment 21 are in strip structure 61; and the plurality of through holes 6 provided on the top of the cavity compartment 22 are in circular structure 62. Under the same area, the through holes in strip structure 61 can more effectively disperse stress than the through holes in circular structure 62, thereby improving the structural strength of the liquid compartment, more effectively promoting fluid exchange between the inside and outside of the liquid compartment 21, and helping to achieve more uniform energy distribution and absorption during the collision process. The through holes in circular structure 62 help to optimize air circulation inside the cavity compartment 22, thereby providing additional cushioning effect during the collision process; the through holes in circular structure 62 are simpler in manufacturing process than the through holes in strip structure 61, which helps to reduce production cost and improve production efficiency. Strip structure 61 focuses more on fluid exchange and structural strength improvement, while circular structure 62 focuses more on air circulation and stress reduction.

[0043] The friction energy dissipation bottom plate 3 is a long strip-shaped friction structure uniformly fixed to the bottom of the compartment-type energy absorption box 2. During the collision process, energy can be dissipated by friction with the ground, providing additional anti-collision protection.

[0044] The mode conversion running assembly 4 includes an axle 41, a tire 42, and a hydraulic lifting mechanism 43. The tire 42 is connected through the axle 41 and can be fixed or unlocked through a swing shaft 411. The hydraulic lifting mechanism 43 is composed of a motor, a hydraulic cylinder 432, and a hydraulic foot 431, which is used to switch between the anti-collision working state and the towing state. When towing is needed, the hydraulic lifting mechanism 43 can lift the compartment-type energy absorption box 2, so that the tire 42 can rotate on the ground to tow the compartment-type energy absorption box 2; when anti-collision is needed, the hydraulic lifting 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 and the contact area with the ground.

[0045] The tire 42 is provided with a fixing hole 421 for fixing the swing shaft 411; the swing shaft 411 can fix or unlock the tire 42 by inserting or pulling out of the fixing hole 421 on 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 converted 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 operating requirements, for example, in the anti-collision working state requiring high stability, the tire 42 can be firmly fixed on the axle 41; and in the towing state requiring flexible movement, the tire 42 can be unlocked and easily rotated.

[0046] The early warning mechanism 5 includes a signal processor and a warning flash lamp, a large-size electronic display screen 51, a directional loudspeaker and a camera electrically connected to the signal processor. The camera is used to collect detection data of road conditions, the signal processor analyzes and processes these data, and sends a warning signal through the directional loudspeaker. The warning flash lamp and the large-size electronic display screen 51 are arranged on the top of the compartmented energy-absorbing box 2 and used to visually remind passing vehicles.

[0047] Further, the middle shaft 7 is arranged on the rear side steel plate 202, which is an important supporting structure of the compartmented energy-absorbing box 2 and can enhance the structural strength of the entire box. This helps to better absorb and disperse impact force during the collision process, and the middle 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.

[0048] A method for anti-collision buffering of a heavy anti-collision early warning vehicle, comprising the following steps:

[0049] S1, during road maintenance work, the anti-collision early warning vehicle is towed to the front of the work area, the early warning mechanism 5 is started, and the early warning vehicle is converted from the towing state to the anti-collision working state, so as to form an anti-collision buffer zone in front of the work area;

[0050] S2, when a small vehicle mistakenly enters or loses control and enters the anti-collision buffer zone, it will collide with the elastic energy-absorbing crash panel 1; if the vehicle speed is small, the small vehicle can be stopped by the deformation of the elastic crash panel and the deformation of the compartmented energy-absorbing box 2, at this time the elastic energy-absorbing crash panel 1 provides the first energy dissipation, and the deformation of the compartmented energy-absorbing box 2 provides the second energy dissipation; if the vehicle speed is large, in addition to the first and second energy dissipations, the friction energy dissipation bottom plate 3 of the anti-collision early warning vehicle generates moving friction with the ground to provide the third energy dissipation;

[0051] S3, when a large vehicle mistakenly enters or loses control and enters the anti-collision buffer zone, the first, second and third energy dissipations are the same as step S2, and the friction force increased by the downward pressure of the large vehicle on the elastic crash panel provides the fourth energy dissipation; during the collision stopping process, the anti-collision early warning vehicle will drive the large vehicle forward until it stops, stopping the large vehicle;

[0052] S4, when the heavy anti-collision early warning vehicle ends work and needs to be transferred, the hydraulic jacking mechanism 43 of the mode conversion traveling assembly 4 jacks up the compartmented energy-absorbing box 2, and is converted to the towing state, and the heavy anti-collision early warning vehicle is towed away from the work site by a tow truck.

[0053] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the above specific embodiments.
