Description

Technical Field

[0001] This utility model belongs to the field of anti-collision vehicle technology, specifically relating to a 120K anti-collision buffer vehicle suitable for high-speed conditions. Background Technology

[0002] During highway maintenance, construction, or accident response, crash buffer vehicles are typically deployed to absorb the collision energy of vehicles that accidentally intrude, ensuring the safety of on-site personnel. However, existing crash buffer vehicles are often structurally inadequate for high-speed collisions (such as at 120 km / h), lack high-speed energy-absorbing structures, have expensive energy-absorbing pad replacements, unstable rollover mechanisms, and delayed warning systems, failing to achieve effective active protection and rapid response, thus posing significant safety hazards. Utility Model Content

[0003] In view of the technical problems existing in the above-mentioned crash protection vehicles, this utility model provides a 120K crash protection buffer vehicle suitable for high-speed conditions.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A 120K anti-collision buffer vehicle suitable for high-speed operating conditions includes a chassis, a cargo box, an intelligent warning device, a light warning device, an anti-collision buffer device, and a buffer pad flipping device. The cargo box is fixed to the chassis, the light warning device and the intelligent warning device are installed on the upper part of the cargo box, the buffer pad flipping device is installed at the rear of the chassis, and the anti-collision buffer device is installed at the rear of the buffer pad flipping device.

[0006] The anti-collision buffer device includes a primary anti-collision pad and a secondary anti-collision pad, which are hinged together. The primary anti-collision pad is used for low-speed collision buffering, and the secondary anti-collision pad is used for high-speed collision energy absorption.

[0007] The primary and secondary anti-collision pads are connected by two sets of hydraulic cylinders, namely cylinder one and cylinder two. Cylinder one is hinged to the primary anti-collision pad via a first pin, cylinder two is hinged to the primary anti-collision pad via a first pin, cylinder one is hinged to the secondary anti-collision pad via a first pin, and cylinder two is hinged to the secondary anti-collision pad via a first pin, which is used to adjust the buffer displacement and buffer stroke. The secondary anti-collision pad is filled with honeycomb aluminum.

[0008] The buffer pad flipping device includes a left support base, a right support base, a mounting base, a flipping platform, and two flipping cylinders, namely a left cylinder and a right cylinder. Both the left and right support bases are fixed to the chassis. The mounting base is connected to the left and right support bases respectively via a second pin three. The flipping platform is hinged to the mounting base via a second pin one and a second pin two. The mounting base is hinged to the left cylinder via a cylinder bolt one, and to the right cylinder via a cylinder bolt two. The flipping platform is hinged to the left cylinder via a cylinder bolt four, and to the right cylinder via a cylinder bolt three. The flipping cylinders drive the flipping platform to flip relative to the chassis, thereby achieving the retraction and extension control of the anti-collision buffer device.

[0009] The light warning device consists of a first crossbeam, a second crossbeam, a first column, a second column, a first square tube, a second square tube, a first foot support, a second foot support, a front panel, and multiple high-brightness LED warning lights. The first crossbeam is welded and fixed to the first and second columns, the second crossbeam is welded and fixed to the first and second columns, the first and second square tubes are welded and fixed to the first and second crossbeams respectively, the front panel is welded and fixed to the first and second columns, the first foot support is welded and fixed to the first column and the cargo box, and the second foot support is welded and fixed to the second column and the cargo box. The high-brightness LED warning lights are fixed to the first crossbeam, the second crossbeam, the first square tube, the second square tube, and the front panel, forming a three-dimensional warning structure.

[0010] The intelligent early warning device includes a camera, a radar speed measurement module, a rotating warning light, a loudspeaker, and a voice control system. The camera, radar speed measurement module, rotating warning light, and loudspeaker are all electrically connected to the voice control system and are used to identify the distance and speed of oncoming vehicles and output multimodal warning signals.

[0011] The primary anti-collision pad has a modular and detachable structure, which can be quickly replaced according to working conditions.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. Adaptable to high-speed working conditions, significantly improving protection capabilities. This utility model is specifically designed to cope with high-speed collisions of up to 120 km / h. It adopts a multi-stage energy-absorbing structure. The first-stage buffer pad is used to mitigate low-to-medium speed collisions (80K), and the second-stage buffer pad is used for high-speed collisions (120K). It can effectively reduce the impact force brought by high-speed collisions and ensure the safety of personnel and equipment in the construction area.

[0014] 2. Modular structural design reduces maintenance and replacement costs. The buffer pad assembly adopts a modular and detachable structure, especially the primary buffer pad, which can be quickly replaced according to working conditions, simplifying maintenance and saving costs. In low-to-medium speed collisions (80K), only the primary buffer pad needs to be replaced; in high-speed collisions (120K), both the primary and secondary buffer pads need to be replaced. This is suitable for environments requiring long-term, repeated operation, enhancing the equipment's economy and sustainable use capabilities.

[0015] 3. The structure is flip-up, balancing operation and passage. By incorporating a buffer pad flip-up device, the anti-collision device can automatically switch between its working and transport states. This allows the vehicle to meet comprehensive protection requirements during on-site construction while maintaining good maneuverability and passability, significantly improving operational efficiency and vehicle dispatch flexibility.

[0016] 4. The intelligent early warning system comprehensively enhances perception and response capabilities. The early warning system integrates multiple functional modules such as radar speed measurement, video recognition, audio-visual prompts, and voice alarms. It can perceive the speed and distance of vehicles approaching from behind in real time and proactively issue multimodal early warning signals based on judgment logic, intervening in potential risks in advance and reducing the accident rate.

[0017] 5. Multi-dimensional visual early warning system to meet all-weather construction needs. The scientifically laid-out lighting warning device uses high-brightness LED lights deployed at different heights and directions to form a three-dimensional visual warning system. It can provide significant prompts at night and in low visibility conditions such as rain and fog, effectively reminding oncoming vehicles to avoid the construction area.

[0018] 6. System synergy enhances overall safety protection. Key systems (energy-absorbing structure, overturning mechanism, early warning device) are highly integrated, forming multiple protective barriers through synergy. This creates a closed-loop safety system at the construction site, encompassing proactive early warning, buffering and energy reduction, and passive protection, comprehensively improving the inherent safety level during highway maintenance operations.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. These descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the claims of this utility model. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0029] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] In this embodiment, as Figure 1 As shown, the 120K anti-collision buffer vehicle suitable for high-speed working conditions includes a chassis 1, a cargo box 2, an intelligent warning device 3, a light warning device 4, an anti-collision buffer device 5, and a buffer pad flipping device 6. After the vehicle travels to the working area, the cargo box 2, which is fixed on the chassis 1, serves as the basic load-bearing structure. The light warning device 4 and the intelligent warning device 3 installed on the upper part of the cargo box 2 enter the ready-to-start state. The buffer pad flipping device 6 installed at the rear of the chassis 1 and the anti-collision buffer device 5 connected to its rear are ready to switch states according to the work requirements. All components form a complete working system according to their fixed installation positions.

[0032] Furthermore, such as Figure 3As shown, when a vehicle collides with the anti-collision buffer device 5, the articulated primary anti-collision pad 501 and secondary anti-collision pad 502 work together. In the case of a low-speed collision, the primary anti-collision pad 501 first contacts and absorbs the collision energy, playing a low-speed buffering role; in the case of a high-speed collision, after the primary anti-collision pad provides initial buffering, the secondary anti-collision pad 502 further intervenes, absorbing high-speed collision energy through its own structure, thus achieving graded protection.

[0033] Furthermore, when a collision occurs, the anti-collision buffer device 5 is activated. The primary anti-collision pad 501 first contacts the colliding object. At this time, cylinder 1 503 is hinged to the primary anti-collision pad 501 via first pin 1 505 and to the secondary anti-collision pad 502 via first pin 3 507; cylinder 2 504 is hinged to the primary anti-collision pad 501 via first pin 2 506 and to the secondary anti-collision pad 502 via pin 4 508. The two sets of cylinders extend and retract under the action of the collision force, adjusting the relative buffer displacement and stroke of the primary and secondary anti-collision pads 501 and 502, gradually dissipating the collision force. In the case of a high-speed collision, the honeycomb aluminum filling inside the secondary anti-collision pad 502 undergoes structural deformation with the collision force. Through the compression of the honeycomb structure, it further absorbs high-energy collision energy, working in conjunction with the buffering action of the primary anti-collision pad 501 and the cylinders to minimize the transmission of impact force.

[0034] Furthermore, such as Figure 4 , Figure 5 As shown, when switching to the working state, the buffer pad flipping device 6 is activated. The left support 601 and the right support 603 are fixed to the chassis 1, providing stable support for the device; the mounting base 602 is connected to the left support 601 and the right support 603 through the second pin three 611 to maintain a stable position. The left hydraulic cylinder 616 is hinged to the mounting base 602 through the hydraulic cylinder bolt one 610 and to the flipping table 606 through the hydraulic cylinder bolt four 615; the right hydraulic cylinder 613 is hinged to the mounting base 602 through the hydraulic cylinder bolt two 612 and to the flipping table 606 through the hydraulic cylinder bolt three 614. The two hydraulic cylinders extend synchronously, pushing the flipping table 606 to flip downwards around the second pin one 607 and the second pin two 609 connected to the mounting base 602 until the anti-collision buffer device 5 is in a horizontal working position. When switching to the passage mode, the left hydraulic cylinder 616 and the right hydraulic cylinder 613 retract synchronously. Through the transmission of the aforementioned hydraulic cylinder bolts and pins, the tilting table 606 is driven to tilt upward, and the anti-collision buffer device 5 is retracted to the rear of the chassis 1, thus completing the state switch.

[0035] Furthermore, such as Figure 2As shown, when the light warning device 4 is activated, all components work together to form a warning system. Crossbeam 401 is welded and fixed to column 403 and column 404; crossbeam 402 is welded and fixed to column 403 and column 404; square tube 405 and square tube 406 are welded and fixed to crossbeam 401 and crossbeam 402 respectively; front plate 410 is welded and fixed to column 403 and column 404; foot support 408 is welded and fixed to column 403 and cargo box 2; foot support 409 is welded and fixed to column 404 and cargo box 2. These welded connections ensure the stability of the device structure. At this time, multiple high-brightness LED warning lights 407 fixed on crossbeam 1 401, crossbeam 2 402, square tube 1 405, square tube 2 406 and front panel 410 light up simultaneously. Because the components are distributed at different heights and directions, the lit warning lights form a three-dimensional warning structure. During the day, they provide strong light to alert oncoming vehicles, and at night or in low visibility conditions, they clearly outline the construction area, ensuring that oncoming vehicles can recognize the warning signal from multiple angles.

[0036] Furthermore, when the intelligent early warning device 3 is working, the camera and radar speed measurement module collect the distance and speed information of oncoming vehicles in real time. This information is transmitted to the voice control system that is electrically connected to it. Based on the information analysis results, the voice control system drives the rotating warning light to flash and the loudspeaker to issue voice prompts, realizing multimodal early warning of oncoming vehicles and timely reminding them to avoid the construction area.

[0037] Furthermore, when the primary anti-collision pad 501 is damaged due to low- or medium-speed collisions or needs to be replaced according to the working conditions, its modular and detachable structure allows for quick disassembly of the connecting parts and replacement of the new primary anti-collision pad 501. Maintenance can be completed without complicated operations, effectively shortening downtime and reducing maintenance costs.

[0038] The above description only describes the preferred embodiments of the present utility model. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model, and all such changes should be included within the protection scope of the present utility model.
