Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of warning signs, in particular to a real-time warning sign for road conditions. BACKGROUND

[0002] A warning sign is a device used to remind drivers of the specific conditions of the road segment to be passed in front, and has the function of preventing road accidents.

[0003] In winter, it is often rainy and snowy on the road, which causes the road to freeze and wet, and vehicles passing through this section of road are prone to side slipping, causing traffic accidents and posing a safety hazard to other vehicles on the road. Therefore, a road warning sign needs to be placed between the rear vehicle and the accident vehicle, and a flashing warning light and alarm are needed to remind the driver behind of the specific conditions of the road in front, so that the driver can take effective measures to avoid accidents in time.

[0004] However, in actual use, due to the large amount of rain and snow in winter, the warning sign will be blocked after a long period of time, affecting the analysis of the specific conditions of the road in front by the driver behind, thus leading to misjudgment of the road by the driver, and the driver cannot avoid danger in time, which is not conducive to the safety of the driver.

[0015] This invention has at least the following beneficial effects:

[0016] By placing warning signs on both sides of the road in winter, drivers can be reminded to make accurate judgments about the road ahead and take effective evasive measures, thereby reducing the probability of accidents. Since there is more rain and snow in winter, the wiping mechanism can wipe the snow attached to the main surface of the warning sign at regular intervals, thereby preventing the warning words on the surface of the warning sign from being obscured, which would prevent drivers from seeing the main body of the warning sign properly and making incorrect judgments about the road ahead, increasing the driving danger on winter roads. In addition, on multi-lane roads, drivers see the warning sign at different angles, and it is easy to make it difficult to see the content on the surface of the warning sign when the light is reflected or the angle is insufficient.

[0017] The rotating mechanism allows the main body of the warning sign to rotate back and forth, causing the warning sign body to move in a manner similar to a person rotating. This enhances the driver's attention to the main body of the warning sign and allows the driver to clearly observe the contents of the main body from different positions. This helps the driver to quickly and clearly understand the accurate road conditions ahead. Furthermore, the wiping mechanism keeps the main body of the warning sign clean, which helps the driver to clearly and accurately understand the accurate road conditions ahead, reducing the probability of accidents and protecting the safety of drivers driving on roads in winter.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-9 The present invention provides a technical solution:

[0031] Example 1,

[0032] A real-time road condition warning sign includes a main body 1, which can be erected on both sides of the location where vehicles will pass in winter to remind drivers of the actual conditions of the road ahead, thereby increasing the driver's reaction time in special road sections, helping drivers to take effective measures to avoid risks, reducing the occurrence of road accidents, and increasing vehicle driving safety.

[0033] The main body 1 of the warning sign is equipped with reminder plates 2 on both sides. These plates can swing up and down on both sides of the main body 1 of the warning sign when powered by electricity, thereby increasing the attention of the driver who is driving the vehicle and reducing the possibility that the driver will not be able to see the contents of the main body 1 of the warning sign.

[0034] Solar panel 3 is located at the top of the main body 1 of the warning sign and is used to charge the main body 1 of the warning sign. When the main body 1 of the warning sign is working on both sides of the road, it can store electrical energy for the battery of the main body 1 of the warning sign, which can save electricity and help protect the environment.

[0035] Wiping mechanism 4 is located on the surface of the warning sign body 1 and is used to wipe the surface of the warning sign body 1. When the warning sign body 1 is working on the road in winter, and the content on the surface of the warning sign body 1 is obscured by adverse conditions such as rain and snow, the mechanism can wipe the snow on the surface of the warning sign body 1 at regular intervals to prevent the warning sign body 1 from being obscured and thus prevent the driver from not being able to understand the accurate road conditions ahead.

[0036] The rotating mechanism 5 is located at the lower end of the warning sign body 1. It is used to drive the warning sign body 1 to rotate at multiple angles to provide warning. When the warning sign body 1 is working on both sides of the road, it can drive the warning sign body 1 to imitate the movement of pedestrians, increase the driver's attention to the warning sign body 1, and help remind the person driving the vehicle to better understand the accurate road conditions ahead.

[0037] By displaying the real-time road conditions ahead in winter on the surface of the warning sign body 1 and placing it on both sides of the road, the warning plate 2 is controlled to rotate on one side of the warning sign body 1. Under the sunlight of the solar panel 3, the warning plate 2 is continuously powered, thus saving energy and protecting the environment. When the road encounters rain or snow in winter, the wiping mechanism 4, driven by the warning plate 2, continuously wipes the surface of the warning sign body 1 to prevent snow from accumulating on the surface of the warning sign body 1, which would hinder the driver's observation of the content on the surface of the warning sign body 1 and increase the safety hazards of driving vehicles. Under the operation of the rotating mechanism 5, the warning sign body 1 can mimic the movement of pedestrians, which deepens the driver's attention to the warning sign body 1 and allows drivers in multiple lanes to observe the content on the top of the warning sign body 1 from different angles. This helps drivers to understand the accurate road conditions ahead more quickly. With the simultaneous action of the wiping mechanism 4, it ensures that the driver can accurately and quickly understand the content on the surface of the warning sign body 1 and take effective measures in a timely manner to reduce the probability of accidents on winter roads.

[0038] The wiping mechanism 4 includes a first wiping rod 40 slidably connected to the surface of the warning sign body 1. This rod can slide on the surface of the warning sign body 1 and periodically wipe away snow accumulation, allowing drivers to clearly see the contents of the warning sign body 1. A connecting rope 41 is fixedly connected to the upper end of the first wiping rod 40, which can be pulled from the lower end to the upper end of the warning sign body 1 to complete one wiping operation. A first fixed pulley 42 and a second fixed pulley 43 are fixedly connected to the surface of the warning sign body 1, which can change the direction of force on the connecting rope 41, facilitating the pulling of the first wiping rod 40 on the surface of the warning sign body 1. Both the first fixed pulley 42 and the second fixed pulley 43 are slidably connected to the connecting rope 41. A cylinder 44 is wound around the surface of the connecting rope 41, allowing the connecting rope 41 to wrap around the surface of the cylinder 44 and control the length of the connecting rope 41. This allows the cylinder 44 to rotate and shorten the length of the connecting rope 41, enabling the first wiping rod 40 to slide upwards along the surface of the warning sign body 1. One end of the cylinder 44 is fixedly connected to a sliding member 45, which allows the sliding member 45 to slide on the surface of the solar panel 3 when the reminder plate 2 rotates and drives the first wiping rod 40 to move. This allows the sliding member 45 to remove snow from the surface of the solar panel 3, which is beneficial for the solar panel 3 to continuously contact sunlight and continuously charge the warning sign body 1. One end of the cylinder 44 is slidably connected to a fixing frame 46, which can restrict the rotation of the cylinder 44 and the first ratchet 48, which is beneficial for the continuous contraction and charging of the spring 47. When a certain upper limit is reached, the spring 47 releases the reminder potential energy. The inner wall of the cylinder 44 is fixedly connected to the spring 47, which can compress the spring 47 and accumulate elastic potential energy when the first ratchet 48 rotates, which is beneficial for the spring 47 to release elastic potential energy when it reaches a certain state.

[0039] One end of the mainspring 47 is fixedly connected to a first ratchet 48, which can rotate in one direction and compress the mainspring 47 under the restriction of a second ratchet 49. The surface of the first ratchet 48 is slidably connected to the second ratchet 49, which allows the first ratchet 48 to slide on the surface of the second ratchet 49, compressing the mainspring 47 and accumulating elastic potential energy. When the first ratchet 48 and the second ratchet 49 are pressed against each other, the elastic potential energy of the mainspring 47 is preserved, and it is also beneficial for the mainspring 47 to be compressed again to store energy. One end of the second ratchet 49 is fixedly connected to a first spring 410, which allows the second ratchet 49 to slide on the inner wall of the fixed frame 46 and compress the first spring 410 when the first ratchet 48 slides on the surface of the second ratchet 49. The first spring 410 is fixedly connected to the fixed frame 46, and the second ratchet 49 is slidably connected to the fixed frame 46. The side of the first ratchet 48 near the second ratchet 49 is fixedly connected to a rotating rod 411, which can rotate synchronously with the first gear 412, so that when the first gear 412 rotates, it compresses the mainspring 47 and accumulates elastic potential energy.

[0040] The rotating rod 411 is rotatably connected to the inner wall of the second ratchet 49. One end of the rotating rod 411 is fixedly connected to the first gear 412, allowing the second gear 413 to rotate in the forward direction, thus driving the first gear 412 to rotate. The surface of the first gear 412 meshes with the second gear 413, allowing the second gear 413 to mesh and drive the first gear 412 to rotate in the forward direction, and not mesh with the first gear 412 when the second gear 413 rotates in the reverse direction. One end of the second gear 413 is fixedly connected to a sliding rod 414, allowing the second gear 413 to move within the warning sign body 1. The inner wall slides, so that when the second gear 413 rotates in the forward direction, it meshes with the first gear 412, and when the second gear 413 rotates in the reverse direction, it separates from the first gear 412. The slide rod 414 is slidably connected to the warning sign body 1. The surface of the second gear 413 is meshed with a half gear 415, which allows the reminder plate 2 to rotate on one side of the warning sign body 1, driving the half gear 415 to rotate repeatedly in the same direction. This is beneficial for the half gear 415 to rotate back and forth in the forward and reverse directions on the inner wall of the warning sign body 1, and to mesh with and drive the second gear 413 to rotate synchronously. The half gear 415 is fixedly connected to the reminder plate 2.

[0041] With the solar panel 3 charging the warning plate 2, it swings back and forth on one side of the warning sign body 1, driving the half gear 415 to rotate back and forth in both directions. When the half gear 415 rotates in the forward direction, it drives the second gear 413 to rotate in the forward direction. At the same time, the second gear 413 meshes with and drives the first gear 412 to rotate. The first gear 412 drives the rotating rod 411 and the first ratchet 48 to rotate, causing the first ratchet 48 to slide on the surface of the second ratchet 49 and compress the first spring 410 and the second ratchet 49 to slide on the inner wall of the fixing frame 46. At the same time, the rotation of the first ratchet 48 compresses the spring 47 to accumulate elastic potential energy. After the spring 47 has accumulated a certain amount of elastic potential energy, the spring 47 separates from the fixing frame 46. Simultaneously, the spring 47 drives the cylinder 44 to rotate, causing the connecting rope 41 to wind around. On the surface of the cylinder 44, the first wiping rod 40 slides upward along the surface of the warning sign body 1. When it reaches the upper end of the warning sign body 1, it returns to the lower end of the warning sign body 1 under the action of gravity, so that the spring 47 can accumulate elastic potential energy again and retract the connecting rope 41 to drive the first wiping rod 40 to slide on the surface of the warning sign body 1. When the half gear 415 rotates in the opposite direction, it drives the second gear 413 to rotate in the opposite direction and slide on the inner wall of the warning sign body 1. At the same time, the second gear 413 separates from the first gear 412, which is beneficial for the warning plate 2 to swing multiple times and drive the first wiping rod 40 to wipe the snow on the surface of the warning sign body 1. This makes it easier for drivers to accurately know the road conditions ahead in winter when there is sudden rain or snow, thus reducing the accident rate on winter roads.

[0042] A second spring 416 is fixedly connected to the inner wall of the cylinder 44, allowing the inclined plate 417 to reciprocate within the cylinder 44. This facilitates continuous contact and compression between the inclined plate 417 and the ring 418, causing the ring 418 to slide on the surface of the cylinder 44, compressing the inclined plate 417 and causing it to reciprocate. One end of the second spring 416 is fixedly connected to the inclined plate 417, allowing it to press against the ratchet groove 419, causing the ring 418 to rotate unidirectionally on the surface of the cylinder 44. Under the action of gravity, the first wiping rod 40 pulls the connecting rope 41 to rotate in the opposite direction, causing the ring 418 to rotate in the opposite direction and rotate on the surface of the cylinder 44, so that the first wiping rod 40 can return to the initial position on the surface of the warning sign body 1. The inclined plate 417 is rotatably connected to the inner wall of the cylinder 44, and the ring 418 is rotatably connected to the surface of the cylinder 44. When the cylinder 44 rotates, the ring 418 can be driven to rotate synchronously, or rotate in the opposite direction on the surface of the cylinder 44 under the pull of the connecting rope 41.

[0043] The inner wall of the ring 418 is provided with a ratchet groove 419, which can be pressed against the inclined plate 417. When the cylinder 44 rotates, the ratchet groove 419 presses against the inclined plate 417, causing the ring 418 to rotate synchronously. This causes the connecting rope 41 to retract onto the surface of the ring 418, pulling the first wiping rod 40 to move. The inclined plate 417 is slidably connected to the ratchet groove 419, and the ring 418 is fixedly connected to the connecting rope 41. Under the action of the second spring 416, the inclined plate 417 contacts and presses against the ratchet groove 419. When the cylinder 44 rotates, it causes the inclined plate 417 and the ring 418 to rotate in the forward direction, reducing the length of the connecting rope 41. This causes the first wiping rod 40 to slide upward along the surface of the warning sign body 1. Under the action of gravity, the first wiping rod 40 slides in the opposite direction on the surface of the warning sign body 1, and pulls the connecting rope 41 to extend its length, and pulls the ring 418 to slide on the surface of the cylinder 44. This causes the ratchet groove 419 to continuously squeeze the inclined plate 417, and the inclined plate 417 to reciprocately squeeze the second spring 416. This is beneficial for the first wiping rod 40 to return to its initial position on the surface of the warning sign body 1 when it moves to the upper end of the warning sign body 1, so that the first wiping rod 40 can wipe the snow on the surface of the warning sign body 1 at regular intervals, ensuring the driving safety of the driver.

[0044] The inner wall of the warning sign body 1 is provided with an arc-shaped groove 420, which allows the half gear 415 to mesh and drive the second gear 413 to rotate when the half gear 415 rotates in the opposite direction. Under the action of friction, the second gear 413 slides on the inner wall of the arc-shaped groove 420 under the drive of the slide rod 414 and separates from the first gear 412. The arc-shaped groove 420 is slidably connected to the slide rod 414.

[0045] The sliding member 45 includes a first bevel gear 421 fixedly connected to one end of the cylinder 44. When the cylinder 44 rotates, it drives the first bevel gear 421 to rotate, simultaneously driving the second bevel gear 422 to rotate. The surface of the first bevel gear 421 meshes with the second bevel gear 422, driving the first pulley 423 to rotate, thus transmitting power to the second wiping rod 430. One end of the second bevel gear 422 is fixedly connected to the first pulley 423, transmitting the power of the second bevel gear 422. Through friction, it drives the first belt 424 to rotate at the same speed. The surface of the first pulley 423 is slidably connected to the first belt 424, driving the second pulley 425 to rotate, causing the third pulley 426 to rotate. One end of the 4 is slidably connected to the second pulley 425, which allows the second pulley 425 and the third pulley 426 to maintain their rotation direction when the solar panel 3 changes direction. This is beneficial for the second wiping rod 430 to continuously wipe the snow off the solar panel. The second pulley 425 is rotatably connected to the main body 1 of the warning sign. One end of the second pulley 425 is fixedly connected to the third pulley 426, which can rotate at the same speed as the third pulley 426 under the drive of the second belt 427. This helps to maintain the stability of the second wiping rod 430. The surface of the third pulley 426 is slidably connected to the second belt 427, which can drive the fourth pulley 428 and the fifth pulley 429 to rotate, and at the same time drive the second wiping rod 430 to move.

[0046] The surface of the second belt 427 is slidably connected to the fourth pulley 428 and the fifth pulley 429, which can maintain the movement trajectory of the second belt 427 and facilitate the stable sliding of the second wiping rod 430 on the surface of the solar panel 3. The fourth pulley 428 and the fifth pulley 429 are both rotatably connected to the solar panel 3. The second wiping rod 430 is fixedly connected to one side of the second belt 427, which can intermittently wipe the snow off the solar panel 3. The second wiping rod 430 is slidably connected to the surface of the solar panel 3.

[0047] When the cylinder 44 rotates and pulls the first wiping rod 40 to wipe the snow on the surface of the warning sign body 1, the cylinder 44 drives the first bevel gear 421 and the second bevel gear 422 to rotate, causing the first pulley 423 to rotate due to friction, which in turn drives the first belt 424 and the second pulley 425 to rotate. At the same time, the second pulley 425 drives the third pulley 426 to rotate, and the third pulley 426 drives the second belt 427 to move due to friction, causing the fourth pulley 428 and the fifth pulley 429 to rotate at the same speed. This allows the second wiping rod 430 to slide back and forth on the surface of the solar panel 3 under the action of the second belt 427. This facilitates the second wiping rod 430 to intermittently wipe the snow off the solar panel 3 and continuously charge the warning sign body 1, which is beneficial for the continuous swinging of the warning board 2 and for driving the spring 47 to continuously store energy.

[0048] A trapezoidal block 431 is fixedly connected to one end of the mainspring 47 connected to the cylinder 44. This block can cooperate with the trapezoidal groove 432 to fix one end of the mainspring 47 to the inner wall of the cylinder 44. This facilitates the release of elastic potential energy by the mainspring 47 to rotate the cylinder 44 when the trapezoidal block 431 separates from the fixing frame 46. The inner walls of the cylinder 44 and the fixing frame 46 are provided with trapezoidal grooves 432, which, through compression and friction, allow the trapezoidal block 431 to contact and fix with the fixing frame 46, maintaining the stability of the mainspring 47 during energy storage. The trapezoidal block 431 and the trapezoidal groove 432... The sliding connection allows the trapezoidal block 431 at one end of the spring 47 to contact the trapezoidal groove 432. While the spring 47 is continuously storing energy, it maintains stability. This is beneficial because when the spring 47 stores a certain amount of energy, it drives the trapezoidal block 431 to overcome the friction between the trapezoidal groove 432, causing the trapezoidal block 431 to separate from the trapezoidal groove 432. At the same time, the spring 47 releases its elastic potential energy, causing the cylinder 44 to rotate, reducing the length of the connecting rope 41, and causing the first wiping rod 40 to slide on the surface of the warning sign body 1.

[0049] The inner wall of the fixed frame 46 is provided with a limiting groove 433, which allows the first ratchet 48 to slide on the surface of the second ratchet 49, pressing the second ratchet 49 to slide on the inner wall of the fixed frame 46, so that the second ratchet 49 moves up and down in a straight line, maintaining the continuous energy storage state of the mainspring 47. The surface of the second ratchet 49 is provided with a limiting block 434 to prevent the second ratchet 49 from rotating on the inner wall of the fixed frame 46 under the pressure of the first ratchet 48, thereby destroying the energy storage state of the mainspring 47. The limiting block 434 is slidably connected to the limiting groove 433, and the fixed frame 46 is rotatably connected to the rotating rod 411. By allowing the limiting block 434 to slide on the inner wall of the limiting groove 433, the second ratchet 49 slides back and forth in a straight line inside the fixed frame 46 when the first ratchet 48 slides on the surface of the second ratchet 49. This is beneficial for the mainspring 47 to store energy, and when it reaches a certain level, it drives the cylinder 44 to rotate and retract the length of the connecting rope 41.

[0050] Example 2,

[0051] The rotating mechanism 5 includes a base 50 slidably connected to the lower end of the warning sign body 1, which maintains its connection to the ground, preventing the fixing frame 46 from tipping over and obstructing the driver's view of the warning sign's surface during rotation. A motor 51 is fixedly connected to the upper end of the base 50, providing continuous power for the warning sign's rotation under manual control. One end of the motor 51's output shaft is rotatably connected to a crank 52, which rotates continuously inside the base 50 under the motor 51's drive. One end of the crank 52 performs a coaxial circular motion, pushing one end of the connecting rod 53 to perform a circular motion. The crank 52 is rotatably connected to the base 50, and one end of the crank 52 is fixed. A connecting rod 53 is connected. When one end of the connecting rod 53 rotates under the drive of the crank rod 52, the other end follows and moves back and forth, causing the turntable 54 to swing. One end of the connecting rod 53 is slidably connected to the turntable 54, which can rotate on the inner wall of the base 50 under the push of one end of the connecting rod 53. The turntable 54 is rotatably connected to the base 50. The arc surface of the turntable 54 is slidably connected to the gear plate 55, which can slide on the surface of the turntable 54 and mesh with the third gear 56 to drive it to rotate. The surface of the gear plate 55 is meshed with the third gear 56, which can drive the warning sign body 1 to rotate. The third gear 56 is rotatably connected to the base 50 and fixedly connected to the warning sign body 1.

[0052] The motor 51 drives the crank 52 to rotate, causing one end of the crank 52 to drive the connecting rod 53 to swing. One end of the connecting rod 53 pushes the turntable 54 to rotate on the inner wall of the base 50, causing the turntable 54 to drive the gear plate 55 to mesh with the third gear 56. This allows the third gear 56, driven by the motor 51, to intermittently drive the warning sign body 1 to swing left and right, thereby increasing the driver's attention to the warning sign. In conjunction with the initial mechanism, it keeps the surface of the warning sign body 1 clean, allowing the driver to quickly and directly understand the accurate road conditions ahead and take timely and effective measures to protect driving safety.

[0053] Rectangular blocks 57 are fixedly connected to both ends of the arc surface of the turntable 54. When the turntable 54 contacts the rectangular blocks 57, the turntable 54 drives the third gear 56 to rotate. The gear plate 55 slides on the arc surface of the turntable 54. When it does not contact the rectangular blocks 57, the third gear 56 will not drive the warning sign body 1 to rotate. This is beneficial for intermittently driving the warning sign body 1 to rotate back and forth and swinging the reminder plate 2 to enhance the driver's attention to the warning sign. The two rectangular blocks 57 are slidably connected to the turntable 54 respectively.

[0054] The disorder mechanism 6 includes a sliding cavity 60 fixedly connected to the inner wall of the turntable 54. This cavity accommodates a steel ball 61, which slides irregularly back and forth within it. The steel ball 61 is slidably connected to the inner wall of the sliding cavity 60. When it attracts a magnetic sheet 64, it connects two adjacent electrodes, generating a current within the inner wall of the warning sign body 1. This current, combined with the existing swing motor 7 inside the warning sign body 1, drives the warning plate 2 to swing back and forth. The inner wall of the sliding cavity 60 has multiple positive electrodes 62 and negative electrodes 63. With the connection of the steel ball 61, two adjacent different electrodes can be connected, generating a positive current that drives the swing motor 7 to rotate forward. Alternatively, when the steel ball 61 connects two identical electrodes, a reverse current is generated, driving the swing motor 7 to rotate in the opposite direction. This causes the warning plate 2 to move irregularly on one side of the warning sign body 1, which helps to increase drivers' attention to the warning sign body on different roads and protects drivers. For driving safety, a magnetic sheet 64 is fixedly connected to the middle of the two electrodes, which can attract the steel ball 61, making the steel ball 61 and the two electrodes in a relatively stable state. This is beneficial for the current conduction of connecting adjacent electrodes. The magnetic sheet 64 and the steel ball 61 are magnetically connected. The positive electrode 62 and the negative electrode 63 are shape memory alloys. After the shape memory alloy is energized upon contact with the steel ball 61, a current loop is formed inside, which generates heat inside the shape memory alloy. When a certain temperature is reached, deformation occurs, which generates a certain elastic force on the steel ball 61, assisting in the separation of the steel ball 61 from the magnetic sheet 64. It also allows the shape memory alloy a certain reaction time after the steel ball 61 separates from the magnetic sheet 64, when it dissipates heat and returns to its initial state. This can prevent the steel ball 61 from sliding inside the sliding cavity 60 and prevent the steel ball 61 from being attracted to the magnetic sheet 64 again. This helps to maintain the disorder of the steel ball 61 sliding inside the sliding cavity 60.

[0055] When the rotating mechanism 5 drives the warning sign body 1 to perform intermittent reciprocating motion, the turntable 54 rotates while simultaneously driving the disorder mechanism 6 to move, causing the steel ball 61 to slide on the inner wall of the sliding cavity 60. During this movement, the steel ball 61 attracts the magnetic sheet 64 and connects the current between adjacent pole pieces, thereby controlling the forward and reverse rotation of the swing motor 7. This causes the warning plate 2 to swing irregularly on one side of the warning sign body 1, which helps to enhance the driver's observation of road warning information. At the same time, when the rotating mechanism 5 completes one rotation, the sliding cavity 60 is subjected to the centrifugal force generated when the turntable 54 rotates and stops, causing the steel ball 61 to separate from the magnetic sheet 64. The steel ball 61 then slides back on the inner wall of the sliding cavity 60 and re-attracts the remaining magnetic sheets 64, thereby generating different currents on the inner wall of the warning sign body 1. This facilitates the irregular movement of the warning plate 2 and ensures the driver's driving safety.
