[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0026] Example:

[0027] like Figures 1 to 7As shown, this utility model provides a highway curve blind spot warning device, including a base 11 and a fixing rod 12. The fixing rod 12 is mounted on the base 11, providing a supporting foundation for the entire device and ensuring its placement beside the highway curve. The fixing rod 12 is equipped with a fixing component and a convex mirror 26. The fixing rod 12 serves as a carrier, providing an installation position for the components. The fixing component includes a mounting seat 13, which is rotatably connected to the convex mirror 26. This rotatable connection allows for easy adjustment of the angle of the convex mirror 26, better adapting it to the visibility requirements of different curves and providing optimal visibility for passing vehicles. The convex mirror 26 is equipped with a self-cleaning component, which includes an arc-shaped scraper 27. The arc-shaped scraper 27 is positioned on the convex mirror 26 and can scrape the surface of the convex mirror 26 to clean dust, rainwater, and other dirt adhering to it, keeping the convex mirror 26 clean and ensuring good visibility. The fixing rod 12 is equipped with a detection radar 32 and a warning light 33. The base 11 contains a controller 34, which is electrically connected to both the detection radar 32 and the warning light 33. Through the electrical connection between the detection radar 32, the warning light 33, and the controller 34, the detection radar 32 can monitor vehicles in the blind spot of curves and transmit the information to the controller 34. The controller 34, based on the received information, controls the warning light 33 to issue corresponding warning signals, promptly reminding the driver to pay attention to vehicles in the blind spot and ensuring driving safety. The controller 34 can be an S7-1200 model controller; the detection radar can be an ARS-430 millimeter-wave radar.

[0028] like Figure 2 , 4 As shown in Figure 5, the fixing assembly also includes two sets of semi-hoops 14. One end of the two sets of semi-hoops 14 is rotatably connected to each other via a rotating shaft 15, and the other end is connected to the mounting base 13. The fixing rod 12 is provided with multiple sets of positioning ring grooves 16, and the two sets of semi-hoops 14 are installed in one of the positioning ring grooves 16. With the arrangement of the two sets of semi-hoops 14, the rotating shaft 15, and the positioning ring grooves 16, the fixing assembly can be easily installed in the positioning ring grooves 16 at different heights on the fixing rod 12. The opening and closing of the semi-hoops 14 is achieved through the rotating shaft 15, which facilitates installation and disassembly. At the same time, the height of the fixing assembly on the fixing rod 12 can be adjusted according to actual needs.

[0029] One end of the mounting base 13 is a hollow cylinder with two sets of guide grooves 17 inside. Each set of guide grooves 17 contains a fixing post 18 and a spring 19. The fixing post 18 is connected to the mounting base 13 via the spring 19. A limiting ring 21 is provided at the open end of the guide groove 17. The fixing post 18 extends and retracts within the guide groove 17 due to the elastic force of the spring 19, and the limiting ring 21 prevents the fixing post 18 from detaching from the guide groove 17, thus achieving elastic fixation and adjustment of the components connected to the mounting base 13. A detachable protruding ring is provided on the fixing post 18. When the protruding ring is in place, the fixing post 18 will not slide out of the guide groove 17. One end of the fixing post 18 extends out of the guide groove 17. To disassemble, the fixing post 18 can be pulled and rotated for removal. The semi-hoop 14, connected to the mounting base 13, is a semi-cylindrical end with a guide rail groove 22 and a fixing groove 23. The fixing post 18 slides along the guide rail groove 22 and then engages with the fixing groove 23. By setting the guide rail groove 22 and the fixing groove 23, a sliding track can be provided for the fixing column 18, and after the fixing column 18 slides into place, it can be locked into the fixing groove 23, so as to achieve a stable and adjustable connection between the half hoop 14 and the mounting base 13.

[0030] like Figure 5 , 6 As shown, both sets of semi-hoops 14 have L-shaped grooves 24 on their inner walls, and the mounting base 13 has two sets of locking blocks 25, which are respectively locked into the two sets of L-shaped grooves 24. The L-shaped grooves 24 and locking blocks 25 further enhance the stability of the connection between the mounting base 13 and the semi-hoops 14, preventing relative rotation or displacement between the two during use.

[0031] like Figure 2 , 3 As shown, the self-cleaning assembly also includes a connecting rod 28 and a first drive motor 29. The first drive motor 29 is located on one side of the convex mirror 26. The output shaft of the first drive motor 29 is connected to the arc-shaped scraper 27 via the connecting rod 28. Through the arrangement of the first drive motor 29 and the connecting rod 28, the first drive motor 29 provides power to drive the arc-shaped scraper 27 via the connecting rod 28, moving the arc-shaped scraper 27 onto the convex mirror 26. The first drive motor 29 is a linear-rotational hybrid motor. A second drive motor 31 is located at the connection between the arc-shaped scraper 27 and the connecting rod 28. The output shaft of the second drive motor 31 is connected to the arc-shaped scraper 27. Both the first drive motor 29 and the second drive motor 31 are electrically connected to the controller 34. Through the connection between the second drive motor 31 and the controller 34, the controller 34 can control the second drive motor 31 according to the actual situation, allowing the arc-shaped scraper 27 to perform circular motion on the convex mirror 26, thereby achieving the cleaning of the convex mirror 26.

[0032] like Figure 2 , 7As shown, a chassis 35 and a battery 36 are mounted on the fixing rod 12, and a controller 34 is also located inside the chassis 35. A solar panel 37 is mounted on the top of the fixing rod 12, and the battery 36 is electrically connected to both the solar panel 37 and the controller 34. Through the arrangement of the chassis 35, battery 36, and solar panel 37, solar energy can be converted into electrical energy by the solar panel 37 and stored in the battery 36. The chassis 35 provides protective space for the battery 36 and controller 34, and the battery 36 provides power support for the operation of the entire device, enabling the device to operate autonomously and improving its energy independence and ease of use.

[0033] The detection radar 32 is a millimeter-wave radar, and the warning light 33 is a three-color warning light. By using millimeter-wave radar as the detection radar 32 and the three-color warning light 33, the distance and speed of vehicles in the blind spot of the curve can be monitored. The three-color warning light 33 uses different colors to intuitively convey different levels of warning information to the driver, such as green for safety, yellow for caution, and red for danger, enabling the driver to react quickly and ensuring driving safety.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In use, the solar panel 37 first starts working, converting solar energy into electrical energy under sunlight and storing it in the battery 36 located inside the casing 35, providing power for the entire device. The millimeter-wave radar 32 continuously monitors blind spots on road curves. Once a vehicle enters the monitoring range, it transmits relevant vehicle information, such as distance and speed, to the controller 34 located in the casing 35 inside the base 11. Based on the received data, the controller 34 determines the degree of danger of the vehicle and controls the tri-color warning light 33 to emit warning lights of corresponding colors. If the oncoming vehicle is far away and traveling at a normal speed, the warning light 33 displays green, prompting the driver to proceed normally; if the oncoming vehicle is traveling at a high speed or is close, the warning light 33 turns yellow, reminding the driver to slow down and drive cautiously; when the oncoming vehicle situation is urgent, the warning light 33 displays red, strongly warning the driver to stop or take evasive action. Regarding the cleaning of the convex mirror 26, when stains appear on the surface of the convex mirror 26 affecting visibility, the controller 34 will control the first drive motor 29 to start according to a preset program. The first drive motor 29 can drive the connecting rod 28 via its output shaft. Driven by the first drive motor 29, the connecting rod 28 first moves the arc-shaped scraper 27 to the surface of the convex mirror 26. Once the arc-shaped scraper 27 reaches the designated position, the first drive motor 29 drives the arc-shaped scraper 27 to move in a circular motion around the edge of the convex mirror 26, cleaning the convex mirror 26. For installation and adjustment, the two sets of semi-hoops 14 are opened via the rotating shaft 15 and installed in the positioning ring grooves 16 at different heights on the fixed rod 12. Then, the semi-hoops 14 are closed, and through the cooperation of the L-shaped groove 24 on the inner wall of the semi-hoops 14 with the locking block 25 on the mounting base 13, and the sliding of the fixing column 18 along the guide rail groove 22 and its insertion into the fixing groove 23, a stable connection is achieved between the mounting base 13 and the semi-hoops 14, thereby fixing the mounting base 13 onto the fixed rod 12. The mounting base 13 and the convex mirror 26 are rotatably connected, allowing for easy adjustment of the angle of the convex mirror 26 according to the actual conditions of the curve to obtain the best field of vision.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
