Description

Technical Field

[0001] The utility model belongs to the technical field of traffic safety and relates to a highway traffic safety cone. Background Art

[0002] Safety cones are a very important type of traffic sign, commonly used for traffic safety purposes such as indicating driving routes and providing safety barriers. They are orange in color and shaped like a cone. Safety cones are made of plastic, typically PVC, which is highly elastic, resistant to scratches and impacts, and highly durable. Currently, safety cones are widely used in road traffic. To ensure traffic safety, safety cones should be inspected for wear or cracks before use. Safety cones should be placed where white lines are drawn on the road, so that drivers can slow down when they see the safety cones to avoid accidents.

[0003] Safety cones alert drivers to road conditions, guide pedestrian and vehicle traffic, and mark dangerous areas. On highways or construction sites, safety cones are often placed at road construction sites or other locations of concern to prompt drivers to slow down and possibly take a detour to ensure the safety of construction workers and passing vehicles. Through their specific shapes and orientations, safety cones help pedestrians and vehicles follow predetermined paths, reducing confusion and the risk of accidents. The presence of safety cones can also highlight potential danger zones, such as potholes or construction sites, prompting people to avoid them and prevent accidents.

[0004] Safety cones are typically deployed and retracted manually. In actual use, they need to be manually placed in specific locations, and when collected, they need to be stacked up in sequence. This method is inconvenient to operate, highly dangerous, and inefficient. These issues are primarily manifested in the following ways: 1. Manual intervention is required to deploy and retract the safety cones, posing a safety hazard during the operation; 2. Manual deployment and retraction of safety cones increases the labor cost of road traffic maintenance; 3. Existing methods of deploying and retracting safety cones are inefficient, time-consuming, and labor-intensive, making rapid deployment and retrieval impossible. Therefore, in order to address these issues, there is an urgent need to further improve and perfect the structure and functionality of existing safety cones. Utility Model Content

[0082] Embodiment 5:

[0083] See also Figure 1 This embodiment discloses a road traffic safety cone, comprising a conical airbag package 2, a conical airbag disc 4, and a cylindrical base 5. The safety cone can be inflated and deflated by an air pump 23. After the airbag is inflated to form a cone, the safety cone can be deployed and used normally. At the same time, the safety cone can be intelligently moved and deployed at a fixed point using the liftable electric wheels and control unit 21 installed on the safety cone. Figure 2 As shown, after the safety cone completes its deployment task, the air pump can be used to extract the gas in the airbag. After the airbag shrinks, the safety cone returns to its cylindrical shape as a whole and automatically returns to the recovery area to complete the intelligent recovery function.

[0084] The airbag disc is connected to the cylindrical base. There is a special connection snap at the bottom of the airbag disc, which can be snapped together with the fixed chassis through a special structure and can also be disassembled. The seals inside and outside the airbag package for inflation, deflating and air pressure detection are made of synthetic rubber material. Figure 1 and Figure 3As shown, the conical airbag package 2 has a rubber handle 1 at the top. The package is made of polyurethane material and cast in a single step using a stamping machine. The interior of the package is lightweight, strong, and tear-resistant, while the coating helps improve the airbag's waterproof properties and increase friction. The exterior of the airbag, used for sealing and connecting the airbag to other components, is made of synthetic rubber. This material must be resistant to high temperatures, oil, and aging to ensure rapid inflation after inflation and facilitate subsequent replacement and recycling. The conical airbag package is tightly connected to the package fixing clip 13 on the conical airbag disc 4 using a special airbag fixing clip 13 designed at the bottom. This clip can be released by external pressure, making it easier for personnel to replace the airbag package. The bottom of the airbag package is equipped with an inflation hole 10 and an exhaust hole 11, which serve as the airbag inflation inlet and exhaust outlet. The bottom of the airbag also has a pressure and temperature sensor signal socket 12, both of which are rubber holes.

When inserted into the inflation hole 10 and exhaust hole 11, the inflation nozzle 16 and exhaust nozzle 17 prevent air bag gas from leaking out of the air bag package. Specifically, the inflation nozzle 16 is inserted into the inflation hole 10, and the exhaust nozzle 17 is inserted into the exhaust hole 11. The airtightness of the pressure and temperature sensor signal socket 12 is ensured by the tight compression of the colloid component between the sensor signal plug 20 and the socket 12.

Four arc-shaped photovoltaic panels 3 are attached to the front of the airbag mounting plate 4 by adhesive bonding. These panels, consisting of four arc-shaped photovoltaic panels, are installed on the portion of the airbag mounting plate 4 that is not covered by the airbag and can replenish power for the battery inside the safety cone.

[0086] like Figure 5 and Figure 6 As shown, the airbag fixing plate 4 is provided with four fixing holes 7 for fixing the airbag package 2; four photovoltaic panel signal sockets 8 for connecting the photovoltaic panel signal plug 19; a central limiting hole 9 for connecting the central limiting column 18 to complete the limiting fixation of the airbag fixing plate 4 and the cylindrical base 5; an inflation hole 10 for connecting the inflation nozzle 16; an exhaust hole 11 for connecting the exhaust nozzle 17; and an air pressure and temperature sensor signal socket 12 for connecting the sensor signal plug 20.

[0087] like Figure 7 and Figure 8 As shown, the top of the cylindrical base 5 is designed with a special central limiting column 18 and a fixed lock 15, which can be connected to the airbag fixing plate 4 and locked. At the same time, the airbag fixing plate 4 can be separated from the cylindrical base 5 by pressing the lock inward. Figure 8As shown, a special cross guide groove 6 is designed on the top of the cylindrical base 5 to prevent rainwater from being retained in the gap between the airbag fixing plate 4 and the cylindrical base 5.

[0088] like Figure 7 As shown, an air pump 23 is installed inside the cylindrical base to realize the functions of inflating and deflating the airbag. The air pump has a special two-way pipeline structure, including an inflation nozzle 16, an exhaust nozzle 17, an inflation port solenoid valve 22, an exhaust port solenoid valve 24, an inflation port air guide tube 25, and an exhaust port air guide tube 26. The inflation port solenoid valve 22 and the exhaust port solenoid valve 24 can switch the pipeline channels for inflation and deflating. The control unit 21 can issue instructions to the air pump to complete the inflation of the airbag to form a cone shape or to extract the gas in the airbag to realize the device recovery. When the device is operating in the inflation mode, the inflation port solenoid valve 22 and the exhaust port solenoid valve 24 begin to operate, the inflation nozzle 16 is connected, the exhaust nozzle 17 is closed, the inflation port air duct 25 is connected, and the exhaust port air duct 26 is closed. When the device is operating in the exhaust mode, the inflation port solenoid valve 22 and the exhaust port solenoid valve 24 begin to operate, the inflation nozzle 16 is closed, the exhaust nozzle 17 is connected, the inflation port air duct 25 is closed, and the exhaust port air duct 26 is connected. Steel filters are installed at the air inlet 39 and the air outlet 38 of the two-way pipeline to block external foreign matter and filter impurities and suspended matter in the gas.

[0089] like Figure 7 As shown, the control unit 21 uses the air pressure and temperature sensors 14 to determine the airbag status and replenish or remove air accordingly. In high-temperature environments, the control unit 21 uses the temperature sensor 14 to determine the current temperature of the device. When the temperature exceeds a critical value, the control unit 21 activates the air pump, blowing air into the bottom of the airbag. This air can then be dissipated directly to the airbag package 2 through the air outlet 38 and the penetrating heat dissipation holes in the conical airbag disc 4, providing air cooling. At this point, the control unit 21 activates the inflation port solenoid valve 22 and the exhaust port solenoid valve 24. The inflation nozzle 16 and exhaust nozzle 17 are closed, and the inflation port air duct 25 and exhaust port air duct 26 are connected. The air pump 23 then extracts air through its own air port. The cool air, compressed by the air pump 23, is then blown through the inflation port air duct 25 and exhaust port air duct 26 toward the airbag mounting disc 4. Due to the air holes in the airbag mounting disc 4, the interior of the airbag package 2 can be rapidly cooled.

[0090] like Figure 7 As shown, two batteries 37 are installed inside the cylindrical base. These batteries provide power for the air pump 23, control unit 21, and electrically powered lift wheels 27 within the device. When the device is deployed at a worksite and the batteries run low, the control unit 21 controls the photovoltaic panels to recharge the batteries.

[0091] like Figure 7、 Figure 9 and Figure 10 As shown, a lifting wheel unit 31 is installed at the bottom of the cylindrical base. The lifting wheel unit 31 mainly includes a rubber electric driving wheel 27, a driving wheel lifting screw 28 and an electric driving wheel driver 29. Figure 10 As shown, the device moves according to external instructions through the control unit 21 to issue instructions to the electric driving wheel driver 29, and the electric driving wheel driver 29 controls the driving wheel lifting screw 28 to lower the driving wheel and drive the driving wheel to turn or rotate until the driving device moves to the designated deployment position area. Figure 7 and Figure 9 As shown, after completing the moving task, the control unit 21 sends a command to control the driving wheel lifting screw 28 and drives the rubber electric driving wheel 27 to rise to the inside of the cylindrical base. The entire bottom of the cylindrical base 5 will fall directly to the ground, effectively increasing the contact area and enhancing the stability of the device.

[0092] Electric wheel drives are electric motors integrated into the wheels, directly driving the vehicle. These drives allow each wheel to independently control its speed and torque, opening up entirely new possibilities for vehicle dynamics and driving experience.

[0093] Key features of the electric travel wheel drive include:

[0094] Independent control: Each electric wheel can be controlled independently, which means the vehicle can be controlled more precisely. For example, when turning, different torques can be applied to different wheels to achieve smoother turning.

[0095] Structural simplification: Complex components of traditional vehicles such as engines, gearboxes, and drive shafts have been simplified or replaced, making the overall structure of the vehicle simpler and reducing maintenance costs.

[0096] like Figure 11As shown, a system control unit 21 is mounted within the cylindrical base 5. This control unit 21 controls the air pump assembly 32 to inflate and deflate the airbag. It utilizes an air pressure detection unit 33 and a temperature detection unit 34 to monitor the airbag's pressure and temperature in real time, intelligently determining the status of the airbag package 2 and adjusting the airbag's air supply or draw accordingly. It can also cool the airbag's bottom by air cooling in high-temperature environments. The temperature detection unit 34 includes a temperature sensor. The control unit 21 controls the lifting and driving wheel unit 31 to perform lifting, steering, and driving functions, enabling deployment and recovery of the device. The control unit 21 utilizes its own positioning sensor to determine the device's position. The control unit 21 utilizes a wireless communication unit 35 to communicate with a remote control station or controller, enabling remote remote control and information transmission. The control unit 21 controls the system power supply unit 36 ​​to power the device, monitor the charge level of the battery 37, and utilize the system power supply unit 36 ​​to control the photovoltaic charging unit 40 to recharge the battery. Furthermore, the control unit 21 can program the device to move to a fixed charging dock on the side of a highway for charging. The photovoltaic charging unit 40 includes a photovoltaic power generation panel 3 .

[0097] Based on the above structure, the present invention also discloses a working method of a highway traffic safety cone, see Figure 13 , including the following steps:

[0098] S1. The control unit 21 starts the lifting wheel unit 31, and the control unit 21 controls the movement trajectory of the safety cone by lifting the wheel unit 31, so that the safety cone moves to the target position;

[0100] S3. When the safety cone is recovered, the control unit 21 activates the inflation and deflation unit 32 to discharge the gas in the airbag package 2.

[0101] See also Figure 13 In another feasible embodiment of the present invention, the following modifications are adaptively made according to circumstances. The control unit 21 activates the lifting wheel unit 31, which controls the motion trajectory of the safety cones to move the safety cones to the target position. This enables remote deployment and recovery of the safety cones, improves deployment and collection efficiency, prevents construction workers from being in dangerous environments, and ensures the safety of operators. When placing the safety cones, the control unit 21 activates the inflation and deflation unit 32 to inflate the airbag package 2. When retrieving the safety cones, the control unit 21 activates the inflation and deflation unit 32 to discharge the gas in the airbag package 2, which helps save space, facilitates collection, and improves collection efficiency.
