Description

Technical Field

[0001] This utility model relates to the field of anti-collision buffer vehicle technology, and in particular to a highly protective anti-collision buffer vehicle with sufficient cushioning. Background Technology

[0002] Collision buffer vehicles are veritable "safety guardians" on the road. They feature a unique body structure with a large collision buffer pad at the rear, filled with special energy-absorbing materials such as honeycomb aluminum. Working on an energy absorption mechanism, the buffer pad effectively absorbs collision energy when a vehicle behind loses control and impacts, significantly reducing the impact force and protecting the safety of personnel and equipment working ahead.

[0003] The energy absorption and buffering performance of existing crash cushioning structures needs to be improved, and the overall protective performance needs to be enhanced. Utility Model Content

[0004] The purpose of this invention is to provide a highly protective anti-collision buffer vehicle that can achieve efficient energy absorption and buffering operations, with strong overall protective performance and high practicality.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A highly protective anti-collision buffer vehicle with sufficient cushioning includes a mobile vehicle. A support frame is fixedly connected to the rear of the mobile vehicle. Multiple mounting seats are fixedly connected to the symmetrical side surfaces of the support frame. A buffer cylinder is fixedly installed in the mounting position of each mounting seat. A rotating connecting seat is fixedly connected to the telescopic end of the buffer cylinder. A first connecting rod is rotatably connected to one end of the rotating connecting seat. A second connecting rod is rotatably connected to the symmetrical side surfaces of the support frame. A mounting plate is provided at one end of the first and second connecting rods. An energy-absorbing box is fixedly installed on the outer surface of the mounting plate.

[0007] By adopting the above technical solution, efficient energy absorption and buffering operations can be performed, and the energy absorption box can be installed flexibly and conveniently, making it highly practical.

[0008] Furthermore, the energy-absorbing box is provided with multiple energy-absorbing cavities inside, and multiple energy-absorbing frames with a rhomboid cross-section are fixedly connected to the symmetrical inner walls of the energy-absorbing cavities.

[0009] By adopting the above technical solutions, the energy absorption operation of the energy absorption box can be improved.

[0010] Furthermore, two first connecting rods and two second connecting rods are provided on both symmetrical sides of the support frame. The first connecting rods and the second connecting rods are distributed crosswise, and the intersection of the first connecting rods and the second connecting rods is rotatably connected. One end of the second connecting rod is rotatably connected to a slide block. A slide rail is fixedly connected to both ends of the outer surface of one side of the mounting plate. The slide block is slidably connected in the slide groove of the slide rail. One end of the first connecting rod is rotatably connected to the bottom of the outer surface of one side of the mounting plate.

[0011] By adopting the above technical solution, effective position compensation can be performed when subjected to an impact.

[0012] Furthermore, the buffer cylinder includes a cylinder seat, a piston rod is slidably mounted inside the cylinder seat, a connecting seat is connected to one end of the cylinder seat, a buffer tube seat is threadedly mounted on one side of the outer surface of the connecting seat, a piston block is slidably mounted inside the buffer tube seat, an inner spring is provided inside the buffer tube seat, the two ends of the inner spring respectively abut against the side surface of the piston block and the inner end face of the buffer tube seat, an exhaust hole is provided at the middle position of the piston block, multiple through holes are provided at the edge of one end face of the buffer tube seat, and an exhaust port is provided at the middle position of the other end face of the buffer tube seat.

[0013] By adopting the above technical solution, buffering operations can be effectively achieved.

[0014] Furthermore, an air inlet pipe is fixedly connected to one outer surface of the connecting seat, and a solenoid valve is fixedly installed in the air inlet pipe.

[0015] By adopting the above technical solution, the operation of the buffer cylinder can be effectively controlled.

[0016] Furthermore, two opposing direction indicator lights are fixedly installed on the upper end of one side of the outer surface of the support frame, and multiple indicator lights are fixedly installed on one side of the outer surface of the support frame.

[0017] By adopting the above technical solution, effective nighttime guidance operations can be performed.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. This utility model can provide visibility at night using indicator lights and guide traffic flow using directional indicator lights during operation, thus providing guidance for traffic management. At the same time, it can prevent vehicles from posing a safety threat to construction workers. It can also use the energy-absorbing box set on the support frame for anti-collision protection. Since multiple energy-absorbing chambers are set inside the energy-absorbing box, and multiple energy-absorbing frames with a cross-section of rhombus are fixedly connected to the inner wall of the energy-absorbing chambers, the energy-absorbing box can deform to absorb energy when an external vehicle crashes into it, thus protecting the accidental vehicle. Furthermore, since the energy-absorbing box is mounted on the mounting plate, it can be flexibly disassembled and replaced.

[0020] 2. This utility model provides stable support for the energy-absorbing box through the combination of the first and second connecting rods, and also provides positional compensation for the impact of an unexpected vehicle. When an unexpected vehicle hits the energy-absorbing box, the combined frame of the first and second connecting rods can be folded, at which time the piston rod can retract into the cylinder seat. When the piston rod moves inside the cylinder seat, it can compress the air inside the cylinder seat. When the air pressure inside the cylinder seat is too high, it pushes the piston block to move inside the buffer tube seat. At this time, the inner spring deforms, and the air inside the cylinder seat passes through the through hole at the end of the buffer tube seat, then through the exhaust hole at the middle position of the piston block, and finally exits from the exhaust port at the end of the buffer tube seat. This can achieve a second layer of buffering and energy absorption, and the overall buffering performance is further improved, and the practicality is further improved. Attached Figure Description

[0026] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 , Figure 4 A highly protective anti-collision buffer vehicle with sufficient cushioning includes a mobile vehicle 1. A support frame 2 is fixedly connected to the rear of the mobile vehicle 1. Multiple mounting seats 3 are fixedly connected to the symmetrical side surfaces of the support frame 2. A buffer cylinder 4 is fixedly installed within the mounting position of each mounting seat 3. A rotating connecting seat 6 is fixedly connected to the telescopic end of the buffer cylinder 4. A first connecting rod 7 is rotatably connected to one end of the rotating connecting seat 6. Second connecting rods 8 are rotatably connected to the symmetrical side surfaces of the support frame 2. A mounting plate 9 is provided at one end of each of the first and second connecting rods 7. An energy-absorbing box 12 is fixedly installed on the outer surface of the mounting plate 9. The device has multiple energy-absorbing chambers 13 inside, and multiple energy-absorbing frames 14 with a rhomboid cross-section are fixedly connected to the symmetrical inner walls of the energy-absorbing chambers 13. The energy-absorbing box 12 set on the support frame 2 can be used for anti-collision protection. Since multiple energy-absorbing chambers 13 are set inside the energy-absorbing box 12, and multiple energy-absorbing frames 14 with a rhomboid cross-section are fixedly connected to the inner walls of the energy-absorbing chambers 13, when an external vehicle crashes into the energy-absorbing box 12 out of control, the energy-absorbing box 12 can deform to absorb energy and protect the accidental vehicle. Since the energy-absorbing box 12 is installed on the mounting plate 9, it can be flexibly disassembled and replaced.

[0028] Reference Figure 1 , Figure 3Two first connecting rods 7 and two second connecting rods 8 are provided on both symmetrical sides of the support frame 2. The first connecting rods 7 and second connecting rods 8 are distributed crosswise, and the intersection of the first connecting rods 7 and second connecting rods 8 is rotatably connected. One end of the second connecting rod 8 is rotatably connected to a slide block 11. A slide rail 10 is fixedly connected to both ends of the outer surface of one side of the mounting plate 9. The slide block 11 is slidably connected in the slide groove of the slide rail 10. One end of the first connecting rod 7 is rotatably connected to the bottom of the outer surface of one side of the mounting plate 9. The buffer cylinder 4 includes a cylinder. A piston rod 18 is slidably mounted inside a cylinder seat 16. A connecting seat 17 is connected to one end of the cylinder seat 16. A buffer tube seat 5 is threaded onto the outer surface of one side of the connecting seat 17. A piston block 19 is slidably mounted inside the buffer tube seat 5. An inner spring 20 is installed inside the buffer tube seat 5, with its two ends abutting against the side surface of the piston block 19 and the inner end face of the buffer tube seat 5, respectively. An exhaust hole is located in the middle of the piston block 19. Multiple through holes are located at the edge of one end face of the buffer tube seat 5. An exhaust port is provided at the middle position of the other end face of the pipe seat 5. An intake pipe is fixedly connected to the outer surface of one side of the connecting seat 17, and a solenoid valve is fixedly installed in the intake pipe. The combination of the first connecting rod 7 and the second connecting rod 8 provides stable support for the energy absorption box 12 and also provides position compensation for the impact of an accidental vehicle. When an accidental vehicle hits the energy absorption box 12, the combined frame of the first connecting rod 7 and the second connecting rod 8 can be folded. At this time, the piston rod 18 can retract into the cylinder seat 16. When the piston block 19 moves inside the cylinder seat 16, it can compress the air inside the cylinder seat 16. When the air pressure inside the cylinder seat 16 is too high, it pushes the piston block 19 to move inside the buffer tube seat 5. At this time, the inner spring 20 deforms. The air inside the cylinder seat 16 passes through the through hole at the end of the buffer tube seat 5, then through the exhaust hole at the middle position of the piston block 19, and finally exits from the exhaust port at the end of the buffer tube seat 5. This can achieve a second buffer energy absorption operation, and the overall buffer performance is further improved, and the practicality is further improved.

[0029] Reference Figure 2 Two opposing direction indicator lights 15 are fixedly installed on the upper end of one side of the outer surface of the support frame 2. Multiple indicator lights 21 are fixedly installed on one side of the outer surface of the support frame 2. During work, the indicator lights 21 can be used for visibility at night, and the direction indicator lights 15 can be used to guide traffic flow, providing guidance for traffic management, while avoiding vehicles posing a safety threat to construction workers.

[0030] Working principle: In use, the mobile vehicle 1 is parked at the designated location. Indicator lights 21 are used for nighttime visibility, and directional indicator lights 15 guide traffic flow, providing guidance for traffic management and preventing vehicles from posing a safety threat to construction workers. In case of an accident, the energy-absorbing box 12, mounted on the support frame 2, can be used for collision protection. Because multiple energy-absorbing chambers 13 are set inside the energy-absorbing box 12, and multiple rhomboid energy-absorbing frames 14 are fixedly connected to the inner wall of the energy-absorbing chambers 13, when an out-of-control vehicle impacts the energy-absorbing box 12, the energy-absorbing box 12 can deform to absorb energy, protecting the vehicle from the accident. Furthermore, because the energy-absorbing box 12 is mounted on the mounting plate 9, it can be flexibly disassembled and replaced. During the collision protection process, the first connecting rod 7 and the second... The combined support of the two connecting rods 8 provides stable support for the energy-absorbing box 12 and also provides positional compensation for the impact of an unexpected vehicle. When an unexpected vehicle hits the energy-absorbing box 12, the combined frame of the first connecting rod 7 and the second connecting rod 8 can be folded. At this time, the piston rod 18 can retract into the cylinder seat 16. When the piston rod 18 moves inside the cylinder seat 16, it can compress the air inside the cylinder seat 16. When the air pressure inside the cylinder seat 16 is too high, it pushes the piston block 19 to move inside the buffer tube seat 5. At this time, the inner spring 20 deforms. The air inside the cylinder seat 16 passes through the through hole at the end of the buffer tube seat 5, then through the exhaust hole at the middle position of the piston block 19, and finally exits from the exhaust port at the end of the buffer tube seat 5. This can achieve a second layer of buffering and energy absorption, and the overall buffering performance is further improved.
