Description
Technical Field
[0001] This utility model relates to the field of road protection technology, specifically to a novel anti-collision buffer vehicle. Background Technology
[0002] Collision buffer vehicles are mainly used for mobile maintenance operations, temporary road construction, and emergency response to traffic accidents on highways, urban expressways, elevated roads, and overpasses. Their purpose is to protect personnel and equipment at construction or emergency sites from surrounding traffic hazards, prevent secondary accidents, and significantly reduce the severity of injuries to personnel in involved vehicles. Existing collision buffer vehicle warning lights typically use multiple LED lights combined together, with various shapes such as left arrow lights, right arrow lights, and X-shaped lights achieved by controlling the on / off state of each LED. However, this warning method is not intuitive or prominent enough. Therefore, more prominent lighting warning devices can be installed to reduce the probability of accidents and better ensure the safety of personnel. On the other hand, the collision buffer pad is also a factor. Conventional collision buffer pads are upright when not in use, which not only affects visibility but also driving speed. Therefore, a buffer pad that can lie flat inside the vehicle at a 180-degree angle greatly improves the practicality of the collision buffer vehicle. Combining warning devices with lighting warning devices on the vehicle further enhances the warning effect of the collision buffer vehicle. In conclusion, designing a crash buffer vehicle with more intuitive warning effects, richer functions, and greater practicality is the primary task to meet people's urgent needs.
[0003] Chinese utility model application number 202222151183.X discloses an LED display screen lifting device. Although this utility model is equipped with a liftable light warning device, it does not have a fixed protective frame for the LED screen, nor does it have a horn warning device. Compared with the defects mentioned in the background art, this utility model fails to solve the technical problems.
[0004] Chinese utility model application number 202123090680.5 discloses a collision buffer vehicle. This utility model uses a combination of traditional reflective stickers to warn following vehicles, but the warning effect is not intuitive enough. Compared to the shortcomings mentioned in the background art, this utility model fails to solve the technical problem.
[0005] Chinese utility model application number 202122592691.7 discloses a novel anti-collision buffer vehicle. This utility model uses various LED displays and other combined warning lights mounted on a fixed gantry. While the warning effect is good, the height of the warning devices is limited, making the warning effect slightly insufficient for vehicles at greater distances. Therefore, compared to the shortcomings mentioned in the prior art, this utility model fails to solve the technical problem. Utility Model Content
[0006] The purpose of this utility model is to provide a new type of crash buffer vehicle, which solves the problems of existing technologies such as the lack of intuitiveness of light warning devices, the complexity of the device structure, poor functionality, and the poor practicality of the crash buffer vehicle itself.
[0007] To address this, a novel anti-collision buffer vehicle is proposed, comprising a vehicle body, an anti-collision buffer device assembly at the rear of the vehicle body, and a lighting warning assembly on top of the vehicle body. The lighting warning assembly includes a fixed frame installed inside the vehicle body's cargo box. U-shaped grooves with opposing openings are respectively provided on the left and right sides inside the fixed frame. A slide rail is fixedly installed on the inner wall surface of the U-shaped groove, and the slide rail and U-shaped groove are integrated with the fixed frame. The U-shaped groove within the fixed frame forms a space to restrict the opposing fixing of the LED screen bracket, and the LED screen bracket cooperates with the slide rail within the U-shaped groove to allow the LED screen bracket to rise and fall within the fixed frame. An LED screen is also provided inside the fixed frame in the direction facing the rear vehicle on the LED screen bracket. A lifting cylinder is provided below the LED screen bracket and connected to it, with the other end of the lifting cylinder fixedly connected to the bottom of the fixed frame to control the autonomous rising and falling of the LED screen within the fixed frame.
[0008] The effect is that the fixed frame within the light warning assembly provides simple and effective protection for the LED screen bracket and LED screen inside the frame. A U-shaped groove and a slide rail are set inside the fixed frame, and the LED screen bracket is placed within the U-shaped groove and cooperates with the slide rail, enabling smooth raising and lowering of the LED screen bracket within the fixed frame. Simultaneously, the LED screen is mounted on the surface of the LED screen bracket, thus achieving smooth raising and lowering of the LED screen itself. A lifting cylinder located below the LED screen bracket can freely control the raising and lowering of the LED screen bracket and the surface LED screen as needed. The integrated slide rail, U-shaped groove, and fixed frame structure is more robust and stable. The LED screen itself has high brightness and higher color vibrancy, providing a stronger overall visual impact and thus a more intuitive warning effect. The retractable LED screen is not limited by local environmental factors; it can be raised to the appropriate height according to different situations, ensuring that following vehicles can always see the warning at the appropriate time. When not in operation, the LED screen is lowered and hidden within the fixed frame, neither affecting the footprint of the LED screen nor hindering its effective protection.
[0009] A further improvement is that the structure of the fixed frame consists of two rectangular supports welded together side by side, and multiple support rods for lateral fixation are provided between the two rectangular supports, ultimately forming a fixed frame with a stable exoskeleton support and an internal hollow structure.
[0010] The effect is that the hollow bracket does not lose its own stability and the protective strength of the lamp holder shell, while the overall weight is lighter, which can greatly reduce the load on the crash cushion vehicle.
[0011] A further improvement is that the LED screen bracket has a U-shaped opening structure that is not closed at the bottom, and a horizontal support rod is provided in the middle section of the LED screen bracket, with multiple reinforcing support rods below the horizontal support rod.
[0012] The advantage is that this type of LED screen bracket is lightweight and has good stability, making it very suitable as a carrier for LED screens.
[0013] A further improvement is that the LED screen bracket is detachable from the fixed frame, and the LED screen on the surface of the LED screen bracket is also detachable.
[0014] The benefits are: in real life, detachability means lower repair and replacement costs and easier operation.
[0015] A further improvement is that the anti-collision buffer assembly includes a mounting plate located at the rear of the vehicle body. The mounting plate is hinged to the tilting mechanism, and a pair of first drive cylinders are provided between the mounting plate and the tilting mechanism to control the tilting mechanism to tilt 90° relative to the mounting plate. An anti-collision buffer pad is hinged to the other end of the tilting mechanism, and a pair of second drive cylinders are provided between the tilting mechanism and the anti-collision buffer pad to control the anti-collision buffer pad to tilt 90° relative to the tilting mechanism.
[0016] The effect is that the first and second drive cylinders enable the anti-collision buffer pad to rotate 180° between itself and the mounting plate using the flipping mechanism as the anchor point. After rotating 180°, the anti-collision buffer pad can be placed flat inside the vehicle body, which widens the driving field of vision and also reduces wind resistance during vehicle operation, thereby increasing the vehicle's driving speed.
[0017] Further improvements include: a rear fixed mounting plate and a vehicle body, wherein the rear fixed mounting plate is located at the rear end of the vehicle body; one end of the rear fixed mounting plate is hinged to the side end of the tilting frame; the front of the tilting frame is provided with an anti-collision buffer pad; and a pair of third drive cylinders are provided between the rear fixed mounting plate and the tilting frame, which are used to control the anti-collision buffer pad on the tilting frame to achieve a 90° rotation relative to the rear fixed mounting plate.
[0018] The effect is that, in addition to the aforementioned anti-collision buffer pad that can rotate 180°, an anti-collision buffer pad that can rotate 90° can also be set according to user needs. The third drive cylinder set between the rear fixed mounting plate and the flipping frame allows the anti-collision buffer pad to be set vertically at the rear of the vehicle body. The vertical buffer pad can be lowered more quickly in case of a sudden emergency, enabling a rapid and efficient rescue operation.
[0019] A further improvement is that the interior of the vehicle body is also equipped with a warning system that works in conjunction with the lighting warning assembly.
[0020] The effect is that, considering various factors, while a retractable LED display screen can provide a direct warning effect, it's never too much to have more preventative measures. The horn warning sound combined with the light warning assembly of the warning system creates a stronger visual and auditory impact. It's safe to say that no one can ignore the presence of a crash buffer vehicle parked ahead.
[0021] A further improvement is that a control box is provided at the lower rear of the vehicle body, and the control box contains a motor and a controller. The motor is connected to and controls the light warning assembly, the anti-collision buffer assembly, and the warning system.
[0022] The effect is that the separately set-up control box can promptly activate the working mode of the crash buffer vehicle when there is no time to go to the driver's cab, which is suitable for emergency situations.
[0023] A further improvement is that the rear end of the main beam of the vehicle body is provided with an extended portion, and a rear guardrail is installed at the end of the extended portion.
[0024] The effect is that the rear guardrail further enhances the protection of the crash buffer vehicle. Beneficial effects
[0025] This invention combines a retractable LED screen with a crash cushion vehicle. Utilizing the higher brightness and more vibrant colors of the LED screen, as well as the increased visibility when raised, it provides a more direct warning method for the crash cushion vehicle, offering earlier alerts to vehicles further behind. During non-operating hours, the lowered LED screen provides self-protection. A warning horn device is also included; when a vehicle behind enters a certain speed range and exceeds a certain limit, a loud horn will alert staff and oncoming vehicles, further enhancing safety. The flat-lying cushion further expands the rear vehicle's field of vision and increases the vehicle's speed. A second configuration, a vertical cushion for emergencies, is also available. In summary, this invention features a simple structure, excellent functionality, and enhanced practicality. Attached Figure Description
