Technical Field

[0001] The utility model relates to the technical field of warning signs for safety protection, and specifically relates to a warning sign for safety protection. Background Technique

[0002] A warning sign is a conventional emergency equipment on a vehicle. Its appearance is generally triangular, so it is also called a triangular warning sign. The warning sign must strictly comply with the requirements of the Road Traffic Safety Law and is a passive reflector made of plastic reflective material. The principle is that when the vehicle owner encounters an unexpected traffic accident on the road, the reflective performance of the warning sign is used to remind other vehicles to pay attention and avoid, so as to prevent a secondary accident.

[0003] The utility model with the existing authorization publication number of CN220281252U discloses a triangular warning sign, including: a bracket assembly, which includes a bottom bracket, a first rotating bracket and a second rotating bracket; a strip assembly, which includes a first strip, a second strip and a third strip.

[0004] Adopting the above technical solution, the triangular warning sign according to the utility model has many advantages such as strong applicability and good storage performance, and is easy to be recognized by sensing devices such as cameras, lidars and millimeter wave radars. However, for the above technical solution, the warning sign needs to be held by the user and placed in a suitable position. However, on the highway, the act of holding the triangular warning sign and placing it behind the vehicle itself has a certain degree of danger. Therefore, a remotely controllable triangular sign is needed to protect personal safety.

[0005] Therefore, those skilled in the art provide a warning sign for safety protection to solve the problems raised in the above background technique. Content of the Utility Model

Detailed Description of the Invention

[0023] Please refer to Figures 1-4 , a warning sign for safety protection, including an outer shell 1. A driving mechanism 2 is arranged inside the outer shell 1. The driving mechanism 2 includes two servo motors 201. A battery cover 3 is clamped to the bottom surface of the outer shell 1. A magnet 4 is fixedly connected to the back surface of the outer shell 1. The back surface of the magnet 4 is in contact with the front surface of the remote control 211. By providing the battery cover 3, it is convenient to disassemble the battery to protect the chassis. The magnet 4 is used to adsorb the hand-held remote control device.

[0024] The bottom surface of each servo motor 201 is fixedly connected to the inner bottom wall of the housing 1. The output end of the power of each servo motor 201 is fixedly connected with a power gear 202. Four extension rods 11 are rotatably connected to the bottom surface of the housing 1. An auxiliary wheel 12 is fixedly connected to the inner wall of each extension rod 11. By setting the cooperation of the extension rods 11 and the auxiliary wheels 12, the device is not prone to yaw during movement, playing a role in support and balance maintenance.

[0025] The outer surface of each power gear 202 is meshed with a first speed-changing gear 203. A second speed-changing gear 204 is fixedly connected to the outer surface of each first speed-changing gear 203. Two support frames 10 are fixedly connected to the inner bottom wall of the housing 1. The outer surface of each first speed-changing gear 203 is rotatably connected to the inner wall of the support frame 10. By setting the support frame 10, it plays a role in supporting the first speed-changing gear 203 and the second speed-changing gear 204, ensuring that the first speed-changing gear 203 and the second speed-changing gear 204 rotate more stably.

[0026] One end of each first speed-changing gear 203 away from the second speed-changing gear 204 is rotatably connected to the inner wall of the housing 1. The outer surface of each second speed-changing gear 204 is meshed with a tire gear 205. A hub 206 is fixedly connected to the inner wall of each tire gear 205. The outer surface of each hub 206 is rotatably connected to the inner wall of the housing 1. A battery box 207 is fixedly connected to the inner bottom wall of the housing 1. A signal decoder 208 is fixedly connected to the upper surface of the housing 1. An antenna 8 is fixedly connected to the upper surface of the signal decoder 208. A wear-resistant tire 9 is fixedly connected to the outer surface of each hub 206. By setting the antenna 8, it plays a role in receiving signals in a larger range. The wear-resistant tire 9 is used to directly contact the ground, with a more wear-resistant effect, increasing the service life.

[0027] A warning sign base 209 is fixedly connected to the upper surface of the housing 1. Two warning plates 210 are rotatably connected to the back surface of the warning sign base 209. A remote controller 211 is arranged on the back surface of the housing 1. Four first reflective stickers 5 are fixedly connected to the front surface of the warning sign base 209. Four second reflective stickers 6 are fixedly connected to the front surface of each warning plate 210. By setting the first reflective stickers 5 and the second reflective stickers 6, they both play a role in reflecting light, used to warn the oncoming vehicles behind to pay attention to dodging.

[0028] A buckle 7 is fixedly connected to the inner wall of each warning plate 210. The one sides of the two buckles 7 close to each other are clamped. By setting the buckle 7, it is convenient for the two warning plates 210 to be foldable, saving space, and further improving the speed of preparing the triangular warning sign by using the clamping characteristic of the buckle 7.

[0029] The working principle of the present utility model is as follows: When in use, first, the servo motor 201 and the battery box 207 are electrically connected by wires. Then, the storage battery inside the battery box 207 provides power to drive the rotation of the servo motor 201. The power provided by the servo motor 201 can drive the power gear 202 to rotate. Due to the meshing connection between the power gear 202 and the first speed-changing gear 203, the rotation of the power gear 202 can drive the rotation of the first speed-changing gear 203. Due to the fixed connection between the first speed-changing gear 203 and the second speed-changing gear 204, when the first speed-changing gear 203 rotates, it can drive the rotation of the second speed-changing gear 204. At this time, due to the meshing connection between the second speed-changing gear 204 and the tire gear 205, when the second speed-changing gear 204 rotates, it can drive the rotation of the tire gear 205. Thus, the power provided by the two servo motors 201 can drive the rotation of the two hubs 206. The wear-resistant tires 9 are fixed on the outer surface of the hubs 206, so they can be used for a long time without being easily damaged;

[0030] Before moving the triangular warning sign, first unfold the warning plates 210 at both ends of the warning sign base 209. Due to the mutual snap-connection relationship of the two buckles 7, the two warning plates 210 can be fixed together. Then, the first reflective sticker 5 and the second reflective sticker 6 play a warning role for the oncoming vehicles behind, reminding them to pay attention to avoiding. At this time, the four extension rods 11 can be rotated to extend the auxiliary wheels 12. The transmitter built into the remote controller 211 emits a signal, and then the signal decoder 208 and the antenna 8 receive and decode the signal to control the start or stop of the servo motor 201, achieving the effect of remotely moving the triangular warning sign. For the warning sign used for safety protection, it can be remotely controlled to protect personal safety.

[0031] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
