[0054] According to the traffic warning device 100 of the utility model, as shown in the figure, Figures 1 to 7 Comprise:

[0055] The moving trolley 10 comprises a chassis 11, guide wheels 12 and a moving motor 13 for driving the guide wheels 12 to move. For example, three guide wheels 12 are arranged on the chassis 11, two of which are connected to corresponding moving motors 13, and the other is a universal wheel. The two guide wheels 12 are driven by the corresponding moving motors 13 to realize the turning of the moving trolley 10.

[0056] The warning sign 20 is pivotally connected to the chassis 11 of the moving trolley 10 and can move between the open position perpendicular to the chassis 11 and the closed position parallel to the chassis 11. It can be understood that the warning sign 20 is provided with a reflective or luminous strip for the convenience of warning the vehicles behind. For example, a flexible reflective cloth is pasted on the warning sign 20.

[0057] The camera 30 is installed on the warning sign 20 and is configured to acquire image information of the moving trolley 10 during movement.

[0058] The mobile vehicle 10 performs obstacle avoidance actions based on the image information.

[0059] When a vehicle accident or malfunction occurs, the driver takes out the mobile cart 10 and places it on the ground. The driver then manipulates the warning sign 20 from a closed position parallel to the chassis 11 to an open position perpendicular to the chassis 11. The mobile cart 10 then moves along the road in a direction away from the vehicle. During this process, the camera 30 acquires image information of the mobile cart 10. If obstacles such as central or side guardrails are detected, the mobile cart 10 avoids them, ensuring that its movement remains within the lane of the vehicle involved in the accident. After the accident or malfunction is resolved, the mobile cart 10 moves along the road towards the vehicle until it reaches a designated location. The camera 30 acquires image information of the mobile trolley 10 during its movement. Once an obstacle such as a central or side guardrail is detected, the mobile trolley 10 avoids the obstacle to ensure that its movement remains within the lane of the accident vehicle. Then, it manipulates the warning sign 20 from an open position perpendicular to the chassis 11 to a closed position parallel to the chassis 11, and retracts the traffic warning device 100. Because the warning sign 20 of the traffic warning device 100 can be adjusted between the open and closed positions, its own space occupation is greatly reduced, making it easy to carry. Moreover, by setting up the camera 30, image information in the direction of movement can be acquired in real time to avoid collisions with obstacles.

[0060] In one example of this utility model, such as Figures 2 to 6 As shown, it also includes: a drive mechanism 40,

[0062] In other words, by setting up a drive mechanism 40, the warning sign 20 can be driven to switch between the open and closed positions, thereby greatly improving the automation level of the traffic warning device 100 and facilitating adjustment. For example, the drive mechanism 40 can be a drive motor 41, a telescopic component 42, etc.

[0063] In one example of this utility model, such as Figures 2 to 5 As shown, the drive mechanism 40 includes:

[0064] The driving motor 41 is fixedly installed on the chassis 11, and an output shaft thereof is connected with a pivot shaft of the warning board 20, and is configured to drive the warning board 20 to switch between an open position perpendicular to the chassis 11 and a closed position parallel to the chassis 11 through rotation of the output shaft of the driving motor 41;

[0065] For example, a speed reducer is further included, which is arranged between the output shaft and the pivot shaft, and is used for reducing the rotating speed of the driving motor 41;

[0066] For example, an output end of the speed reducer is connected with the pivot shaft of the warning board 20 through a shaft coupling.

[0067] When the vehicle is in an accident or failure, the driver takes out the mobile trolley 10 and places it on the ground, drives the warning board 20 to adjust from the closed position parallel to the chassis 11 to the open position perpendicular to the chassis 11 through forward rotation of the driving motor 41, and then moves the mobile trolley 10 along the road in a direction away from the vehicle, in the process, the camera 30 acquires image information of the mobile trolley 10 in the moving process, and once an obstacle such as a central or side guardrail is found, the mobile trolley 10 avoids the obstacle to ensure that the movement of the mobile trolley 10 is always in the lane of the accident vehicle, after the vehicle accident or failure is solved, the mobile trolley 10 moves along the road in a direction close to the vehicle until a specified location, in the process, the camera 30 acquires image information of the mobile trolley 10 in the moving process, and once an obstacle such as a central or side guardrail is found, the mobile trolley 10 avoids the obstacle to ensure that the movement of the mobile trolley 10 is always in the lane of the accident vehicle, and then the driving motor 41 drives the warning board 20 to adjust from the open position perpendicular to the chassis 11 to the closed position parallel to the chassis 11 through reverse rotation, and the traffic warning device 100 is stored.
