Description

[Technical Field]

[0001] This utility model relates to the field of road traffic crash protection vehicle technology, and in particular to a crash protection vehicle with a warning device. [Background Technology]

[0002] With the increasing frequency of road construction, maintenance, and various special operations on roads, such as road construction, road rescue, and temporary traffic control, it is often necessary to place crash barriers on the road to ensure the safety of the work area and the workers.

[0003] Currently, most crash avoidance vehicles on the market are equipped with corresponding warning devices, such as warning lights and reflective strips, designed to remind following vehicles to maintain a safe distance and follow traffic instructions. These warning devices are usually installed on the vehicle body using conventional connection methods such as simple bolt fixing or welding, especially the connection between the warning lights and the vehicle body, which is often relatively simple and direct.

[0004] However, in practical applications, this conventional connection method has significant drawbacks. When a crash barrier vehicle encounters an accidental collision, even a relatively minor one, or is subjected to other external impacts, the warning light bracket, which is originally fixed to the vehicle body, can easily become loose or even completely detach from the vehicle body due to the impact force. Once this happens, on the one hand, the warning light bracket may fly off the vehicle body due to inertia, and the flying part itself becomes a new safety hazard, which is very likely to hit nearby vehicles and pedestrians, thus causing secondary injuries; on the other hand, after the warning light bracket is detached, the warning function of the entire crash barrier vehicle will be greatly reduced, and it will no longer be able to effectively convey the necessary signals to vehicles behind, making it difficult for drivers of following vehicles to obtain accurate road conditions and warning information in a timely manner, greatly increasing the probability of subsequent traffic accidents. [Utility Model Content]

[0005] The purpose of this invention is to provide a crash protection vehicle with a warning device, thereby solving the aforementioned problems existing in existing crash protection vehicles.

[0006] This utility model is achieved through the following technical solution:

[0007] A crash avoidance vehicle with a warning device includes a vehicle body, a retractable crash avoidance box connected to the rear of the vehicle body, and a warning component fixedly connected to the vehicle body to transmit signals to vehicles approaching from behind.

[0008] As described above, a collision avoidance vehicle with a warning device includes a rear cargo compartment capable of accommodating a load. The rear of the rear cargo compartment is fixedly connected to the warning assembly. The warning assembly includes a warning light bracket fixedly connected to the rear of the rear cargo compartment. A safety restraint structure is provided between the warning light bracket and the bottom of the rear cargo compartment. When the warning light bracket is separated from the rear cargo compartment due to external force, the safety restraint structure can keep the warning light bracket connected to the rear cargo compartment to prevent the warning light bracket from flying off the vehicle body due to inertia.

[0009] As described above, a collision avoidance vehicle with a warning device includes a safety restraint structure comprising a first restraint connection portion disposed on the warning light bracket and a second restraint connection portion disposed at the bottom of the rear compartment, wherein a restraint connection device is connected between the first restraint connection portion and the second restraint connection portion.

[0010] As described above, in a collision avoidance vehicle with a warning device, the restraint connection device includes an expandable adaptive connector with one end fixed to the first restraint connection portion, and an adjusting connector with adjustable tightness connected to the other end of the adaptive connector.

[0011] As described above, in a collision avoidance vehicle with a warning device, a plurality of light panels are evenly arranged on the side of the warning light holder facing the collision avoidance box, and a reflective film is provided on the surface of the side of the warning light holder facing the collision avoidance box.

[0012] As described above, a collision avoidance vehicle with a warning device has a counterweight box in the rear compartment that matches the size of the compartment body. The counterweight box includes multiple evenly arranged compartments for holding counterweight materials.

[0013] As described above, a crash-proof vehicle with a warning device has crash barriers installed on both sides of the vehicle body.

[0014] As described above, in a collision avoidance vehicle with a warning device, a first warning light is provided on the top of the warning light bracket, and the first warning light cover is provided with a protective cover.

[0015] In the above-described anti-collision vehicle with a warning device, the adjusting connector is a turnbuckle with one end connected to the adapting connector and the other end connected to the second constraint connector.

[0016] In the above-described crash protection vehicle with a warning device, the adaptive connector is a steel cable or chain.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. This utility model provides a safety restraint structure at the bottom of the warning light frame and the rear compartment. When the warning light frame tends to separate from the rear compartment due to external force, the safety restraint structure can keep the warning light frame connected to the rear compartment, preventing it from flying off the vehicle body due to inertia, thus avoiding becoming a new safety hazard. At the same time, it can ensure that the crash avoidance vehicle can continuously and effectively transmit signals to vehicles behind, maintaining the warning function.

[0019] 2. The warning light holder of this utility model has multiple light panels evenly distributed on the side facing the crash box, increasing the range and intensity of the luminous warning, making it easier for following vehicles to notice. In addition, a reflective film is provided on the surface of the warning light holder facing the crash box, which can still remind following vehicles through reflection even when the warning light is not turned on or in low light conditions, further enhancing the overall warning effect.

[0020] 3. The rear compartment is equipped with a counterweight box that matches the size of the compartment. The counterweight box includes multiple evenly spaced compartments for storing counterweight materials. By properly counterweighting, the vehicle body can be more stable when performing protection tasks on the road, and is less prone to shaking or other instability due to external factors.

[0021] 4. The vehicle is equipped with crash barriers on both sides, which can resist collisions from both sides to a certain extent and protect the vehicle, the work area, and the safety of the workers. Compared with some existing technologies that only focus on rear warnings and lack side protection, this provides more comprehensive protection. [Attached Image Description]

Detailed Implementation Methods

[0032] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0033] Please see Figures 1 to 9 This embodiment provides a crash avoidance vehicle with a warning device, including a vehicle body 1. A deployable and retractable crash avoidance box 2 is connected to the rear of the vehicle body 1. A warning component 3, capable of transmitting signals to oncoming vehicles, is fixedly connected to the rear of the vehicle body 1. The crash avoidance box 2 is connected to the rear of the vehicle body 1 and can be deployed and retracted. The specific connection structure can achieve deployment and retraction through a hinged, hydraulic, or pneumatic connection structure. When the crash avoidance vehicle is not in operation, the crash avoidance box 2 is retracted to save space. When operating on the road, the crash avoidance box 2 is deployed to provide additional crash cushioning protection to the rear of the vehicle body, reducing damage to the vehicle in a collision.

[0034] The warning component 3 is fixedly connected to the rear of the vehicle body 1 and is used to convey signals to vehicles approaching from behind. The warning component 3 may include various forms of warning lights, reflective strips, or other visual signal devices to remind following vehicles to maintain a safe distance from the collision avoidance vehicle of this embodiment.

[0035] Specifically, the vehicle body 1 includes a rear cargo compartment 11 capable of accommodating loads. The rear of the rear cargo compartment 11 is fixedly connected to the warning assembly 3. The warning assembly 3 includes a warning light bracket 31 fixedly connected to the rear of the rear cargo compartment 11. A safety restraint structure 32 is also provided between the warning light bracket 31 and the bottom of the rear cargo compartment 11. When the warning light bracket 31 is separated from the rear cargo compartment 11 due to external force, the safety restraint structure 32 can keep the warning light bracket 31 connected to the rear cargo compartment 11 to prevent the warning light bracket 31 from flying off the vehicle body due to inertia.

[0036] In this embodiment, the warning light holder 31 and the rear compartment 11 are preferably welded together, ensuring a stable and reliable connection. In some other embodiments, bolts can also be used for fixing. A safety restraint structure 32 is provided between the warning light holder 31 and the bottom of the rear compartment 11. When the warning light holder 31 is separated from the rear compartment 11 due to an external impact, the presence of the safety restraint structure 32 can keep the warning light holder 31 connected to the rear compartment 11, preventing the warning light holder 31 from flying off the vehicle body due to inertia and avoiding injury to other vehicles or pedestrians. The safety restraint structure 32 can take various forms, such as steel cables, ropes, chains, springs, or other retractable restraint connection devices.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the safety restraint structure 32 includes a first restraint connection portion 321 disposed on the warning light bracket 31 and a second restraint connection portion 322 disposed at the bottom of the rear compartment 11, and a restraint connection device 323 is connected between the first restraint connection portion 321 and the second restraint connection portion 322.

[0038] In this embodiment, the first constraint connection part 321 is disposed on the warning light holder 31 for connection with the constraint connection device 323. The first constraint connection part 321 can take various forms, such as hooks, rings, fixing seats, etc., to ensure that it can be reliably connected with the constraint connection device 323.

[0039] The second constraint connection part 322 is fixedly installed at the bottom of the rear compartment 11 for connection with the constraint connection device 323. The second constraint connection part 322 may be in a form that matches the first constraint connection part 321 to ensure that it can be reliably connected with the constraint connection device 323.

[0040] The constraint connection device 323 is connected between the first constraint connection part 321 and the second constraint connection part 322, and is used to keep the warning light frame 31 connected to the rear compartment 11 when it is separated from the rear compartment 11 due to external force. The constraint connection device 323 can take various forms, such as steel cable, rope, chain, spring, telescopic rod or other telescopic and deployable connection device.

[0041] By setting up a safety constraint structure 32, including a first constraint connection part 321, a second constraint connection part 322 and a constraint connection device 323, the warning light bracket 31 can be effectively prevented from flying off the vehicle body under collision or other external force, thus avoiding injury to other vehicles or pedestrians.

[0042] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the constraint connection device 323 includes an expandable adaptable connector 3231 with one end fixed to the first constraint connection portion 321, and the other end of the adaptable connector 3231 is connected to a tightening connector 3232 whose tightness can be adjusted.

[0043] In this embodiment, the adaptable connector 3231 is part of the constraint connection device 323, with one end fixedly connected to the first constraint connection portion 321. The adaptable connector 3231 can adopt a deployable structure, such as a telescopic rod, a foldable chain, a steel cable, or other deformable connection device. This design allows the adaptable connector 3231 to be deployed when needed to provide the required connection length.

[0044] Adjustable connector 3232 is attached to the other end of adaptable connector 3231 and is used to adjust the tightness of constraint connection device 323. Adjustable connector 3232 can take various forms, such as adjustable bolts, clips, clamps, or other adjustable connection devices. By adjusting adjustable connector 3232, it can be ensured that constraint connection device 323 maintains appropriate tension under normal operating conditions and provides a reliable connection when needed.

[0045] By incorporating the adaptive connector 3231 and the adjusting connector 3232, the restraint connection device 323 can be ensured to provide a reliable connection under various conditions, preventing the warning light bracket 31 from flying off the vehicle body in the event of a collision or other external force, thus avoiding injury to other vehicles or pedestrians. Furthermore, the design of the adjusting connector 3232 allows users to adjust the tightness of the restraint connection device 323 as needed. This ensures that the warning light bracket maintains appropriate tension under normal operating conditions and provides a reliable connection when required.

[0046] Specifically, the adjusting connector 3232 is a turnbuckle with one end connected to the adapting connector 3231 and the other end connected to the second constraint connector 322. This allows the user to easily adjust the tightness of the constraint connector 323 as needed. It ensures that the warning light holder maintains appropriate tension under normal operating conditions and provides a reliable additional connection when the light holder is subjected to external impact.

[0047] Specifically, the adaptive connector 3231 is a steel cable or chain, preferably a chain, which can withstand greater tensile and impact forces to ensure the reliability and stability of the connection. In addition, it is convenient to cooperate with the tightening connector to easily adjust the tightness of the connection, ensuring that the connection between the warning light bracket and the rear compartment maintains appropriate tension under normal working conditions.

[0048] Furthermore, as a preferred embodiment of this solution and not a limitation, the warning light holder 31 is provided with a plurality of light panels 311 evenly on the side facing the crash box 2. The plurality of light panels can be provided with reflective film on the surface of the warning light holder 31 facing the crash box 2 according to road condition markings and traffic information.

[0049] In this embodiment, multiple light panels 311 can indicate traffic information, such as displaying turn signals or stop signals, based on different lighting combinations according to the road conditions where the crash avoidance vehicle is located, thereby improving road safety. More specifically, such as Figure 7 As shown, multiple light panels 311 illuminate to form a left-pointing arrow, indicating that vehicles behind can proceed to the left, and vice versa. Figure 8 The illustration indicates that vehicles should proceed to the right. It should be noted that this is merely an example and does not represent an exhaustive list of all possible lighting combinations for the light panel 311, as those skilled in the art should understand. Furthermore, the reflective film design enhances the visibility of the warning light bracket 31 at night or in low-light conditions, and strengthens the warning to vehicles behind, effectively reducing the occurrence of nighttime accidents.

[0050] Furthermore, as a preferred embodiment of this solution and not a limitation, the rear compartment 11 is equipped with a counterweight box 111 matching the dimensions of the compartment body. The counterweight box 111 includes multiple evenly arranged compartments 1111 for holding counterweight materials. The arrangement of the counterweight box 111 increases the vehicle's weight and inertia, thereby enhancing its collision avoidance capability. In addition, the design of the compartments 1111 allows for the even distribution of counterweight materials, avoiding localized overload or imbalance. This reduces the swaying and tilting of the crash vehicle during operation, improving passenger comfort and safety.

[0051] Furthermore, as a preferred embodiment of this solution and not a limitation, crash barriers 12 are installed on both sides of the vehicle body 1 to provide additional side impact protection and reduce damage to the crash vehicle in side collisions.

[0052] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the top of the warning light holder 31 is provided with a first warning light 312, and the first warning light 312 is covered with a protective cover 3121.

[0053] By mounting a first warning light 312 on top of the warning light bracket 31, a high-position warning signal can be provided, increasing the visibility of the warning signal to vehicles behind. This can improve the warning effect and reduce the probability of traffic accidents, while the design of the protective cover 3121 can protect the first warning light 312 from the influence of the external environment and extend its service life.

[0054] Furthermore, as a preferred embodiment of this solution and not a limitation, the crash box 2 is equipped with a second warning light 21, and the top of the crash box 2 is covered with a reflective film. By providing the second warning light 21 on the crash box 2, additional warning signals can be provided, increasing the visibility of the warning signals to vehicles behind. The reflective film is located on the top of the crash box 2 because when the crash box 2 is deployed, its top faces directly behind; the reflective film design enhances the visibility of the crash box 2 at night or in low-light conditions, further reducing the probability of nighttime accidents.

[0055] Working principle of this utility model:

[0056] The collision avoidance vehicle with warning device of this utility model mainly achieves functions such as collision avoidance, signaling to vehicles behind, and ensuring the stability and reliability of each component by working together through multiple parts such as the collision avoidance box, warning components, safety restraint structure and vehicle counterweight box, thereby improving the safety of road operation, reducing the damage caused by vehicle collisions and reducing the probability of traffic accidents.

[0057] The crash box is attached to the rear of the vehicle body and can be deployed and retracted via articulated, hydraulic, or pneumatic connections. It retracts to save space when the vehicle is not on the road, and deploys when in operation, utilizing its structural characteristics to provide additional crash cushioning protection to the rear of the vehicle, thereby reducing damage to the vehicle in rear-end collisions.

[0058] The warning assembly is fixedly connected to the rear of the vehicle and includes components such as a warning light bracket. It uses various forms of warning lights and reflective strips to transmit signals to vehicles behind, reminding them to maintain a safe distance. For example, multiple light panels can display traffic information (such as turn signals or stop signals) in different lighting combinations depending on road conditions. The first warning light on top of the warning light bracket provides a high-level warning signal, and the second warning light on the crash box also provides an additional warning signal. Furthermore, the reflective film on top of the crash box and on the warning light bracket enhances visibility at night or in low-light conditions, comprehensively strengthening the warning effect for vehicles behind.

[0059] The warning light bracket is fixed to the rear compartment by welding (or bolt connection in other embodiments), and a safety restraint structure is provided between the two. When the warning light bracket is separated from the rear compartment due to external force, the safety restraint structure can keep the warning light bracket connected to the rear compartment, preventing it from flying off the vehicle body due to inertia and causing injury to other vehicles or pedestrians.

[0060] The safety restraint structure is a key innovation of this invention. It includes a first restraint connection portion mounted on the warning light bracket, a second restraint connection portion located at the bottom of the rear cargo compartment, and a restraint connection device connecting the two. The restraint connection device further includes a deployable adaptable connector (such as a steel cable or chain, capable of withstanding significant tensile and impact forces and easily adjustable in tension) fixed at one end to the first restraint connection portion, and an adjustable tension connector (such as a turnbuckle) connected to the other end of the adaptable connector. During normal operation, adjusting the tension connector ensures the restraint connection device maintains appropriate tension. When the warning light bracket is subjected to external impact and tends to separate from the rear cargo compartment, this overall structure functions to maintain the connection.

[0061] The rear compartment is equipped with a counterweight box containing multiple evenly spaced compartments for storing counterweight materials. By properly placing the counterweight materials, the vehicle's weight and inertia are increased, enhancing its collision resistance. Furthermore, the counterweight materials are evenly distributed, preventing localized overload or imbalance, thereby reducing swaying and tilting during operation and improving passenger comfort and safety.

[0062] The vehicle is equipped with crash barriers on both sides. When the vehicle is involved in a side collision, the crash barriers provide additional side impact protection and reduce the damage to the vehicle in a side collision.

[0063] In addition, the first warning light cover on the top of the warning light bracket is equipped with a protective cover. The protective cover can protect the first warning light from the influence of the external environment (such as rain, dust, impact, etc.), extend the service life of the first warning light, and ensure that it can continue to play a warning role effectively.

[0064] The above are implementation methods provided in conjunction with specific content, and it is not intended that the specific implementation of this application is limited to these descriptions. Any methods or structures that are similar to those of this application, or any technical deductions or substitutions made based on the concept of this application, should be considered within the scope of protection of this application.
