Description

Technical Field

[0001] This invention relates to the field of highway early warning technology, and in particular to a flexible barrier device for highway early warning. Background Technology

[0002] In recent years, highway accidents and natural disasters have occurred frequently due to extreme weather and human factors. To address these risks, intelligent monitoring systems are now widely used for real-time monitoring of infrastructure structures. However, once the monitoring system issues a warning, effectively alerting high-speed vehicles upstream of the potential hazard point and prompting them to slow down or stop safely has become a challenge. Traditional warning methods mainly involve installing audible and visual sirens and LED displays upstream of the infrastructure structure. However, due to strong natural light during the day, noise from high-speed driving, and the impact of vehicle sound insulation, the effectiveness of sound and light warnings is greatly reduced. Furthermore, drivers primarily focus on road conditions and are prone to overlooking roadside LED displays. Summary of the Invention

[0003] This invention provides a flexible road warning device to solve the problems of poor warning effect of sound and light alarms during the day and easy to ignore information on roadside display screens.

[0004] This invention provides a flexible road safety warning device, comprising a scissor arm assembly and a light curtain strip mounted on the road surface. The scissor arm assembly includes upper and lower layers of vehicle blocking strips and a first rotating shaft positioned between the upper and lower vehicle blocking strips. The two ends of the light curtain strip are connected to two vehicle blocking strips at one end of the scissor arm assembly via a second rotating shaft. The second rotating shaft is rotatably connected to the vehicle blocking strips and slides along the length of the light curtain strip. The upper end of the upper vehicle blocking strip has multiple protrusions, and the light curtain strip emits light that forms a warning light within these protrusions. A flat-push mechanism is connected to the first rotating shaft at the end of the scissor arm assembly near the light curtain strip. The flat-push mechanism drives the scissor arm assembly to unfold and lay on the road surface or fold to one side of the road surface.

[0005] Preferably, the light curtain strip has a first T-groove on the side near the scissor arm assembly, and the lower end of the second rotating shaft is a T-block, which slides along the first T-groove.

[0006] Preferably, a plurality of light emitters are provided on the side of the light curtain strip away from the scissor arm assembly, and the light emitters are arranged in a one-to-one correspondence with the protrusions on the deployed scissor arm assembly, and the horizontal position of the light emitters is higher than the horizontal position of the vehicle barrier strip.

[0007] Preferably, the pushing mechanism includes: a lead screw, a first motor, and a threaded block. The lead screw is threadedly connected to the threaded block, the threaded block is fixed on the light curtain strip, the light curtain strip slides along the width of the road surface, the front end of the lead screw is rotatably connected to a first rotating shaft, and the first motor is used to drive the lead screw to rotate.

[0008] Preferably, the first rotating shaft connected to the lead screw is provided with a second T-groove, and the front end of the lead screw is provided with a T-head that matches the second T-groove.

[0009] Preferably, the pushing mechanism includes: a second motor, a gear and a rack, the gear and rack meshing together, the rack slidingly connected to the light curtain strip, the light curtain strip being fixed to the ground, the front end of the rack being fixedly connected to a second rotating shaft, and the second motor being used to drive the gear to rotate.

[0010] Preferably, it further includes: a battery, a signal receiver, and a controller, wherein the battery is used to provide power to the first motor and the light transmitter, the controller is communicatively connected to the signal receiver, the first motor, and the light transmitter, and the signal receiver is used to receive warning signals.

[0011] Preferably, the protrusions are made of acrylic light-transmitting material.

[0012] Preferably, the protrusion is a cylinder.

[0013] Preferably, the diameter of the protrusion is 20mm.

[0014] Compared with existing technologies, in this invention, when the scissor lift assembly is deployed and laid on the road surface by the pushing mechanism, two second rotating shafts slide towards each other along the light curtain strip, and the vehicle-stopping strip rotates around the second rotating shaft. When the scissor lift assembly is fully deployed, the light curtain strip emits light to form warning lights within the raised points, and the warning lights on multiple raised points form light strips or light bands. During daytime driving conditions, the scissor lift assembly laid on the road surface has the visual effect of a speed bump, alerting the driver. If the driver does not notice it, the wheels running over the scissor lift assembly will cause vibrations to the vehicle, further alerting the driver to slow down and stop. At night, the light strips or light bands on the scissor lift assembly are more conspicuous, alerting the driver. If the driver does not notice it, the wheels running over the scissor lift assembly will cause vibrations to the vehicle, further alerting the driver to slow down and stop. This invention provides timely and effective warnings to vehicles traveling at high speeds on highways through a combination of visual and vibration warnings. This dual warning system improves the warning effect, reduces the occurrence of safety hazards, prevents potential impacts on infrastructure from the source, and ensures its safe operation. Secondly, both the scissor lift assembly and the warning lights are positioned on the road surface, making them easier for drivers to spot and further improving the warning effect.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0019] See attached document Figure 1 and attached Figure 2This embodiment provides a flexible road safety warning device, including a scissor arm assembly 1 and a light curtain strip 2 installed on the road surface 100. The length direction of the light curtain strip 2 is the same as the length direction of the road surface 100. The scissor arm assembly 1 includes upper and lower layers of vehicle blocking strips 11 and a first rotating shaft 12 installed between the upper and lower vehicle blocking strips 11. There are three sets of first rotating shafts 12, which are distributed along the length direction of the road surface 100. The two ends of the light curtain strip 2 are connected by a second rotating shaft. The second pivot 13 is connected to two vehicle-stopping strips 11 at one end of the scissor lift assembly 1. The second pivot 13 is rotatably connected to the vehicle-stopping strips 11 and slides along the length of the light curtain strip 2. The upper end of the vehicle-stopping strip 11 in the upper layer is provided with multiple protrusions 3. The light curtain strip 2 emits light to form a warning light in the protrusions 3. A flat-push mechanism 4 is connected to the first pivot 12 at one end of the scissor lift assembly 1 near the light curtain strip 2. The flat-push mechanism 4 is used to drive the scissor lift assembly 1 to unfold and lay on the road surface 100 or fold it to one side of the road surface 100. In this invention, when the flat-push mechanism 4 pushes the scissor lift assembly 1 to unfold and lay on the road surface 100, the two second pivots 13 slide towards each other along the light curtain strip 2, and the vehicle-stopping strips 11 rotate around the second pivot 13. When the scissor lift assembly 1 is unfolded into place, the light curtain strip 2 emits light to form a warning light in the protrusions 3, and the warning light on the multiple protrusions 3 forms a light strip or light band. During the daytime, the scissor lift assembly 1, laid on the road surface 100, has the visual effect of a speed bump, alerting the driver. If the driver does not notice it, the wheels running over the scissor lift assembly 1 will cause vibrations to the vehicle, further alerting the driver to slow down and stop. At night, the light strips or bands on the scissor lift assembly 1 are highly visible, alerting the driver. If the driver does not notice it, the wheels running over the scissor lift assembly 1 will cause vibrations to the vehicle, further alerting the driver to slow down and stop. This invention provides timely and effective warnings to vehicles traveling at high speeds on highways through a combination of visual and vibration warnings. This dual warning system improves the warning effect, reduces the occurrence of safety hazards, prevents potential impacts on infrastructure from the source, and ensures its safe operation. Furthermore, both the scissor lift assembly 1 and the warning lights are located on the road surface, making them easy for drivers to spot and further enhancing the warning effect.

[0020] One embodiment of the connection between the vehicle barrier strip 11 and the light curtain strip 2: Refer to the attached document. Figure 5 The light curtain strip 2 has a first T-slot 21 on the side near the scissor arm assembly 1, and the lower end of the second rotating shaft 13 is a T-block 131, which slides along the first T-slot 21. When the scissor arm assembly 1 is unfolded or folded, the vehicle stop strip 11 rotates around the second rotating shaft 13, and at the same time, the T-block 131 at the lower end of the second rotating shaft 13 slides in the first T-slot 21 of the light curtain strip 2.

[0021] As another embodiment of the present invention: refer to the appendix Figure 4Multiple light emitters 22 are provided on the side of the light curtain strip 2 away from the scissor arm assembly 1. Each light emitter 22 corresponds one-to-one with a protrusion 3 on the deployed scissor arm assembly 1. The horizontal position of the light emitters 22 is higher than the horizontal position of the vehicle barrier strip 11. The protrusions 3 on the scissor arm assembly 1 are divided into multiple groups, with the number of groups matching the number of light emitters 22. After the scissor arm assembly 1 is fully deployed, the light emitters 22 and their corresponding group of protrusions 3 are arranged in a straight line. When the scissor arm assembly 1 is deployed, the light curtain strip 2 remains parallel to the road, facilitating the alignment of the light emitters 22 with the protrusions 3.

[0022] One implementation of the horizontal pushing mechanism 4: Refer to the attached document. Figure 3 The pushing mechanism 4 includes a lead screw 41, a first motor 42, and a threaded block 43. The lead screw 41 is threadedly connected to the threaded block 43, which is fixed to the light curtain strip 2. The light curtain strip 2 slides along the width of the road surface 100. The front end of the lead screw 41 is rotatably connected to the first rotating shaft 12. The first motor 42 drives the lead screw 41 to rotate. The threaded block 43 slides along the lead screw 41, causing the light curtain strip 2 to slide along the width of the road surface 100. When the light curtain strip 2 slides, the angle between the two anti-vehicle strips 11 changes, thereby driving the scissor arm assembly 1 to unfold and fold. During this process, the first rotating shaft 12, which is rotatably connected to the lead screw 41, remains stationary, while the remaining first rotating shaft 12 moves along the width of the road surface 100. Specifically, both ends of the light curtain strip 2 are slidably connected to guide rods.

[0023] One embodiment of the lead screw 41 being rotatably connected to the first rotating shaft 12: the first rotating shaft 12 connected to the lead screw 41 is provided with a second T-slot, and the front end of the lead screw 41 is provided with a T-head 411 that is adapted to the second T-slot. When the lead screw 41 rotates, the T-head 411 rotates within the second T-slot.

[0024] Another implementation of the flat-pushing mechanism 4: The flat-pushing mechanism 4 includes a second motor, a gear and a rack. The gear and rack mesh with each other. The rack is slidably connected to the light curtain strip 2. The light curtain strip 2 is fixed on the ground. The front end of the rack is fixedly connected to the second rotating shaft 13. The second motor is used to drive the gear to rotate, which drives the rack to move along the width direction of the road surface 100. In this process, the rack slides with the light curtain strip 2. The rack pushes the first rotating shaft 12 connected to it to move along the width direction of the road surface 100, thereby driving the scissor arm assembly 1 to unfold and fold.

[0025] In another embodiment of the present invention, this embodiment further includes a battery 5, a signal receiver, and a controller. The battery 5 provides power to the first motor 42 and the light emitter 22. The controller is communicatively connected to the signal receiver, the first motor 42, and the light emitter 22. The signal receiver is used to receive warning signals. After the monitoring and warning system issues a warning, it sends the warning signal to the signal receiver. Upon receiving the warning signal, the signal receiver sends a control signal to the controller. The controller controls the first motor 42 to drive the scissor arm assembly 1 to unfold and lay it on the road surface 100. At the same time, the controller controls the light emitter 22 to emit strong light. When the strong light passes through the protrusion 3, it will illuminate it, forming a conspicuous light strip.

[0026] As another embodiment of the present invention: multiple scissor lift assemblies 1 are distributed at intervals along the length of the road. A display screen is installed at the scissor lift assembly 1 downstream of the road. The controller is connected to the display screen. After receiving a warning signal, the controller drives the scissor lift assembly 1 to unfold and the protrusion 3 to light up. At the same time, the warning information is displayed on the display screen. When the driver passes the scissor lift assembly 1, he / she receives visual and vibration warnings. When an abnormality is detected, the warning information on the roadside display screen can provide the driver with a clear warning signal in a timely manner.

[0027] As another embodiment of the present invention: the protrusion 3 is made of acrylic light-transmitting material, and light passing through the protrusion 3 will form a bright light inside it.

[0028] In another embodiment of the present invention, the protrusion 3 is a cylinder.

[0029] In another embodiment of the present invention: the diameter of the protrusion 3 is 20mm, the height of the protrusion 3 is 25mm, and the height of the vehicle-stopping strip 11 is 5mm. Since a height exceeding 5cm can easily lead to loss of vehicle control, the present invention sets the sum of the heights of the vehicle-stopping strip 11 and the protrusion 3 to 35mm.

[0030] In this invention, several flexible road safety warning devices are deployed on the driving lane. After receiving a warning signal through a signal receiver, the controller rotates the screw 41 to unfold the scissor lift assembly 1. Simultaneously, the light curtain strip 2 is energized, emitting light that passes through the protrusions 3 to form a warning light. During daytime driving conditions, the scissor lift assembly 1 serves as a warning once observed by the driver. If the driver does not notice it, the wheels running over the scissor lift assembly 1 will cause vibrations to the vehicle, further warning the driver to slow down and stop. At night, several night vision speed bumps are formed in the perpendicular driving direction (multiple protrusions 3 on the scissor lift assembly 1 form light strips), prompting vehicles to slow down and stop. If the driver does not notice, the wheels running over the scissor lift assembly 1 will cause vibrations to the vehicle, further warning the driver to slow down and stop. This invention provides timely and effective warnings to vehicles traveling at high speeds on highways through a combination of visual and vibration warnings. This dual warning system improves the warning effect, reduces safety hazards, and prevents potential impacts on infrastructure from the source, ensuring its safe operation. Furthermore, the fact that both the scissor lift assembly 1 and the warning light are located on the road surface makes them easy for drivers to spot, further enhancing the warning effect.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
