The first slide groove 5 is arranged along the length direction of the mounting seat 1, and the bottom of the first slide groove 5 is V-shaped. The lower end of the transmission rod 4 is located in the first slide groove 5 and is slidably connected to the bottom of the first slide groove 5, so that the lower end of the transmission rod 4 can slide freely along the bottom of the first slide groove 5. The sleeve 6 is sleeved on the transmission rod 4, and the lower end of the sleeve 6 is located in the first slide groove 5. The left-right moving component is connected to the sleeve 6, and the left-right moving component is used to drive The sleeve 6 moves left and right along the first slide groove 5, and the sleeve 6 drives the transmission rod 4 to move along the bottom of the first slide groove 5, so that the transmission rod 4 moves up and down during the left and right movement. The transmission rod 4 drives the warning light 2 to move up and down along the bottom of the first slide groove 5 through the mounting plate 3. The rotating assembly is respectively connected to the sleeve 6 and the transmission rod 4, and is used to drive the transmission rod 4 to rotate when the transmission rod 4 moves up and down along the sleeve 6, thereby driving the warning light 2 to move up and down during the left and right movement, and rotate during the up and down movement, providing a multi-dimensional visual prompt for the human eye, making the warning component in sharp contrast with the surrounding static environment, avoiding the warning component from blending into the surrounding environment only by flashing, improving the recognition of the warning component on rainy days, thereby improving the warning effect on pedestrians and vehicles, and reducing the incidence of traffic accidents.

[0036] like Figure 2 , Figure 3As shown, the left-right moving assembly includes a transmission block 10, two second cavities 9, two first connecting rods 15, two second connecting rods 16 and a driving assembly. The transmission block 10 is arranged in the mounting seat 1. A first cavity 8 is opened at a position below the first slide groove 5 in the mounting seat 1. The first cavity 8 is arranged along the length direction of the mounting seat 1, that is, the same as the setting direction of the first slide groove 5. The transmission block 10 is arranged in the first cavity 8 and is slidably connected to the inner wall of the first cavity 8 to facilitate the transmission block 10 to slide freely along the first cavity 8. The two second cavities 9 are opened in the mounting seat 1 and are located on both sides of the first slide groove 5. Each second cavity 9 is also arranged along the length direction of the mounting seat 1. Each second cavity 9 is connected to the first slide groove 5 through the second slide groove 7.

The driving assembly is connected to the transmission block 10, and the driving assembly is used to drive the transmission block 10 to move along the first cavity 8. The transmission block 10 drives the two second connecting rods 16 to slide along the two second slide grooves 7 through the two first connecting rods 15, and the two second connecting rods 16 drive the sleeve 6 to move along the first slide groove 5. The sleeve 6 drives the transmission rod 4 to be arranged along the length direction of the mounting seat 1. The transmission rod 4 drives the warning assembly to move left and right through the mounting plate 3. When the lower end of the transmission rod 4 moves along the bottom of the first slide groove 5, the V-shaped structure at the bottom of the first slide groove 5 makes the transmission rod 4 move up and down during the left and right movement, thereby driving the warning assembly to move up and down during the left and right movement, so that the warning assembly forms a sharp contrast with the surrounding static environment, providing multi-dimensional visual stimulation for the human eye.

[0037] like Figure 2 , Figure 3As shown, the driving assembly includes a screw rod 11, a partition 12 and a motor 13. The screw rod 11 is horizontally arranged in the first cavity 8 and arranged along the length direction of the mounting seat 1. One end of the screw rod 11 is rotatably connected to the inner wall of the first cavity 8. The screw rod 11 passes through the transmission block 10 and is threadedly connected to the transmission block 10. The rotation of the screw rod 11 drives the transmission block 10 to move left and right along the first cavity 8. The partition 12 is vertically arranged in the first cavity 8 and is located close to the other end of the screw rod 11. The edge of the partition 12 is connected to the inner wall of the first cavity 8. The fixed connection makes the cavity formed by the first cavity 8 and the side of the partition 12 away from the screw rod 11 a sealed structure to prevent rainwater from entering. The other end of the screw rod 11 passes through the partition 12 and is rotatably sealed and connected to the partition 12. The motor 13 is fixedly arranged in the first cavity 8 and is located close to the other end of the screw rod 11. The output end of the motor 13 is connected to the other end of the screw rod 11. When the motor 13 is started, the motor 13 rotates forward and reverse, driving the screw rod 11 to rotate forward and reverse. The screw rod 11 drives the transmission block 10 to move left and right along the first cavity 8.

[0038] like Figure 4 As shown, the rotating assembly includes two mounting holes 21, two guide rods 20 and two guide grooves 19. The two mounting holes 21 are horizontally opened on the inner wall of the sleeve 6 and are located on both sides of the transmission rod 4. The two guide rods 20 are respectively horizontally arranged in the two mounting holes 21. One end of each guide rod 20 is close to the transmission rod 4. The other end of each guide rod 20 is connected to the bottom of the corresponding mounting hole 21 through a first elastic member 22. The first elastic member 2 facilitates the guide rod 20 to reset after horizontal movement in the corresponding mounting hole 21. The two guide grooves 19 are vertically opened on the transmission rod 4. The positions of the two guide grooves 19 are respectively close to the two guide rods 20. Each guide groove 19 is arranged in an arc shape along the circumference of the guide rod 20. After the side of the guide rod 20 is unfolded The two guide grooves 19 are relatively parallel, and the end of each guide rod 20 is located in the corresponding guide groove 19 and is slidably connected to the inner wall of the guide groove 19. When the transmission rod 4 moves upward, the ends of the two guide rods 20 move relatively downward along the two guide grooves 19. The two guide grooves 19 are arranged in an arc shape and in parallel, which drives the transmission rod 4 to rotate, thereby driving the warning light 2 to rotate. At the same time, the rotation direction of the transmission rod 4 when moving up and down is opposite, which further increases the diversity of the movement modes of the warning component, so that the warning component can give visual prompts from multiple directions, reduce visual blind spots, and further provide multi-dimensional visual prompts for the human eye, so that the warning component forms a sharp contrast with the surrounding static environment, thereby further improving the recognition of the warning component on rainy days.

[0039] like Figure 4As shown, each of the guide grooves 19 is divided into a first vertical portion, an arc portion and a second vertical portion from top to bottom, the upper end of the arc portion is connected to the lower end of the first vertical portion, and the lower end of the arc portion is connected to the upper end of the second vertical portion, that is, the arc portion is connected to the first vertical portion and the second vertical portion respectively, and the first vertical portion and the second vertical portion are respectively located on both sides of the guide rod 20, so that the projection length of the arc portion on the horizontal plane accounts for half of the circumference of the side of the transmission rod 4, so that the transmission rod 4 moves upward first in the process of moving from the lowest point to the highest point at the bottom of the first slide groove 5, so that the two guide rods 20 first move along the two The first vertical portion moves downward, enters the two arc-shaped portions, and drives the transmission rod 4 to rotate 180° in the forward direction, and then enters the two second vertical portions. When the transmission rod 4 moves from the highest point at the bottom of the first slide groove 5 to the lowest point, the above steps are repeated in reverse, driving the transmission rod 4 to rotate 180° in the reverse direction, so that the transmission rod 4 is reset, thereby driving the warning light 2 to move upward and rotate 180° in the forward direction, move downward and rotate 180° in the reverse direction during the left and right movement, thereby further increasing the diversity of the movement modes of the warning component, so that the warning component can give visual prompts from multiple directions.

[0040] like Figure 5 As shown, a moving block 14 is provided at the lower end of the transmission rod 4, and the moving block 14 is rotatably connected to the transmission rod 4. A roller is provided at the lower part of the moving block 14, and the roller is in contact with the bottom of the first slide groove 5. The friction between the lower end of the transmission rod 4 and the bottom of the first slide groove 5 is reduced by the roller, so that the movement of the transmission rod 4 is smoother. A second elastic member 23 is sleeved on the transmission rod 4 at a position between the sleeve 6 and the moving block 14. The two ends of the second elastic member 23 are respectively connected to the lower end of the upper sleeve 6 of the moving block 14. The second elastic member 23 makes the moving block 14 always in contact with the bottom of the first slide groove 5, so that the movement of the transmission rod 4 is more stable.

[0041] like Figure 2 As shown, the bottom of the first slide groove 5 is provided with a plurality of arc-shaped protrusions 24 along its length direction, and the arc-shaped surface of each arc-shaped protrusion 24 faces upward, that is, each arc-shaped protrusion 24 is semi-cylindrical, and each arc-shaped protrusion 24 is provided along the width direction of the first slide groove 5, and the cross-section of each arc-shaped protrusion 24 is connected to the bottom of the first slide groove 5, so that the arc-shaped surface of each arc-shaped protrusion 24 faces upward, so that when the lower end of the transmission rod 4 moves along the bottom of the first slide groove 5, it moves up and down once when passing through each arc-shaped protrusion 24, so that when the two guide rods 20 enter the arc-shaped parts of the two guide grooves 19, they can intermittently rotate forward and reverse, driving the warning light 2 to intermittently rotate forward and reverse by a small amplitude when it rotates forward and reverse by a large amplitude of 180°, thereby further increasing the diversity of the movement modes of the warning component, so that the warning component can give visual prompts from multiple directions.

[0042] like Figure 1 , Figure 2 As shown, the warning component includes a mounting plate 3 and two warning lights 2. The mounting plate 3 is horizontally arranged at the upper end of the transmission rod 4. The two warning lights 2 are symmetrically arranged on the upper part of the mounting plate 3. The position of each warning light 2 is close to the edge of the mounting plate 3, so that each warning light 2 is eccentrically arranged, which facilitates the two warning lights 2 to revolve around the center of the mounting plate 3, thereby further increasing the diversity of the movement modes of the warning component, so that the warning component can give visual prompts from multiple directions.

[0043] like Figure 2 , Figure 5 As shown, a collecting chamber 25 is provided in the mounting seat 1 between the first slide groove 5 and the first cavity 8, and the collecting chamber 25 is connected to the lowest point of the bottom of the first slide groove 5 through a plurality of vertically evenly arranged collecting holes 26, so that rainwater can enter the collecting chamber 25 through the plurality of collecting holes 26 after entering the first slide groove 5, and will not affect the movement of the transmission rod 4 along the first slide groove 5. A plurality of drainage channels 27 are respectively provided near the two ends of the collecting chamber 25 in the mounting seat 1, and each drainage channel 27 is arranged along the length direction of the mounting seat 1, that is, each drainage channel 27 is relatively parallel to the second cavity 9, and each drainage channel 27 is inclined, and the upper end of each drainage channel 27 is connected to the inside of the collecting chamber 25, and the lower end of each drainage channel 27 is connected to the outside of the mounting seat 1, so that the rainwater entering the collecting chamber 25 can be quickly discharged.

[0044] like Figure 6 As shown, a third slide groove 17 is respectively opened at the upper and lower positions near the second connecting rod 16 in each second slide groove 7, and the third slide groove 17 is arranged along the length direction of the second slide groove 7. A slider 18 is arranged in the third slide groove 17, and the slider 18 is slidably connected to the third slide groove 17. The lower part of the slider 18 located at the top is connected to the upper part of the second connecting rod 16, and the upper part of the slider 18 located at the bottom is connected to the lower part of the second connecting rod 16, so that the second connecting rod 16 can move more stably along the second slide groove 7.

[0045] like Figure 1 , Figure 3 , Figure 7As shown, flexible water baffles 29 are respectively provided at the positions of the upper part of the mounting seat 1 near the two sides of the first slide groove 5, each flexible water baffle 29 is arranged along the length direction of the mounting seat 1, each flexible water baffle 29 is inclined, the lower part of each flexible water baffle 29 is connected to the upper surface of the mounting seat 1, the upper parts of the two flexible water baffles 29 are in contact with each other, the sleeve 6 is located between the two flexible water baffles 29 and is in contact with the two flexible water baffles 29 respectively, the two ends of the two flexible water baffles 29 are respectively connected with connecting plates to enclose the upper opening of the first slide groove 5, each flexible water baffle 29 is made of rubber material, and rainwater is blocked by the two flexible water baffles 29 to prevent more rainwater from entering the first slide groove 5. At the same time, the setting of the rubber material can also enable the sleeve 6 to move normally along the first slide groove 5.

[0046] Working principle: On sunny days, turn on the two warning lights 2 so that the two warning lights 2 flash to remind passers-by and vehicles. When encountering rainy days, foggy days and other weather with low visibility, start the motor 13, the motor 13 rotates forward and reverse, driving the screw rod 11 to rotate forward and reverse, the screw rod 11 drives the transmission block 10 to move left and right along the first cavity 8, the transmission block 10 drives the two second connecting rods 16 to slide along the two second slide grooves 7 through the two first connecting rods 15, the two second connecting rods 16 drive the sleeve 6 to move along the first slide groove 5, the sleeve 6 drives the transmission rod 4 to be set along the length direction of the mounting seat 1, and the transmission rod 4 drives the warning light 2 to move left and right through the mounting plate 3.

[0047] When the lower end of the transmission rod 4 moves along the bottom of the first slide groove 5, the V-shaped structure at the bottom of the first slide groove 5 causes the transmission rod 4 to move up and down during the left-right movement, thereby driving the warning light 2 to move up and down during the left-right movement.

[0048] When the transmission rod 4 drives the moving block 14 to move from the lowest point to the highest point at the bottom of the first slide groove 5, it first moves upward, so that the two guide rods 20 first move downward along the two first vertical parts, and then enter the two arc-shaped parts to drive the transmission rod 4 to rotate 180° in the forward direction, and finally enter the two second vertical parts. When the transmission rod 4 moves from the highest point to the lowest point at the bottom of the first slide groove 5, the above steps are repeated in the reverse direction, driving the transmission rod 4 to rotate 180° in the reverse direction, so that the transmission rod 4 is reset, thereby driving the warning light 2 to move upward and rotate 180° in the forward direction, move downward and rotate 180° in the reverse direction during the left and right movement.

[0049] When the lower end of the transmission rod 4 drives the moving block 14 to move along the bottom of the first slide groove 5, it moves up and down once when passing each arc-shaped protrusion 24, so that when the two guide rods 20 enter the arc-shaped parts of the two guide grooves 19, they can intermittently rotate forward and reverse, driving the warning light 2 to intermittently rotate forward and reverse by a small amplitude when rotating forward and reverse by a large amplitude of 180°.
