The embodiments described in this invention are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0042] Reference Figure 1-12 A warning and deceleration device for illegal lane changes between dashed and solid lines includes a fixed deceleration block 1 and a retractable deceleration block 3 arranged on a roadbed component between the dashed and solid lines. The roadbed component includes a roadbed 13, a base course 12 provided on the roadbed 13, and an asphalt surface layer 11 provided on the base course 12. The roadbed component has multiple precast concrete slots 14, which are arranged at intervals. Each precast concrete slot 14 is equipped with a fixed deceleration block 1 and a retractable deceleration block 3.

[0043] The fixed deceleration block 1 is located on one side of the dashed line, and the retractable deceleration block 3 is located on one side of the solid line.

[0044] The fixed deceleration block 1 is fixedly connected to the precast concrete trough 14 by the fixing pin 2. The telescopic deceleration block 3 is located on one side of the fixed deceleration block 1. The telescopic deceleration block 3 is respectively equipped with a trigger force transmission device and an action feedback device.

[0045] The triggering force transmission device includes a triggering device 4, a spring-loaded force transmission lever assembly 5 located below the triggering device 4, and a force transmission arm assembly 6 connected to the spring-loaded force transmission lever assembly 5.

[0046] The action feedback device includes a movable buckle assembly 7, a fixed buckle 8 that is fastened to the movable buckle assembly 7, and a telescopic mechanism 9 located below the movable buckle assembly 7.

[0047] Specifically, refer to Figure 5The spring-loaded force transmission lever assembly 5 includes a rotating shaft lever 501. One end of the rotating shaft lever 501 is connected to the triggering device 4, and the other end of the rotating shaft lever 501 is connected to the force transmission arm assembly 6. A T-shaped plate 504 is provided below the middle position of the rotating shaft lever 501. A housing 506 is provided on the outside of the T-shaped plate 504. A bearing 502 is provided between the top of the T-shaped plate 504 and the rotating shaft lever 501. First rollers 503 are provided on both the left and right sides of the bearing 502. The first rollers 503 are located between the rotating shaft lever 501 and the T-shaped plate 504. A first compression spring 505 is provided at the lower end of the T-shaped plate 504.

[0048] In this embodiment, the lever principle is utilized so that when the lever 501 is subjected to force on the left or right side, the horizontal state can be restored instantly when the force is removed.

[0049] Specifically, refer to Figure 6 The force transmission arm assembly 6 includes a vertically arranged force transmission arm 601 and a force transmission block 602 located below the force transmission arm 601. A second compression spring 603 is provided below the force transmission block 602.

[0050] In this embodiment, the force transmission arm assembly 6 is connected to the following two sets of movable buckle assemblies 7 to transmit force.

[0051] Specifically, refer to Figure 7 The movable buckle assembly 7 consists of two sets, which are respectively located on the left and right sides of the force transmission arm assembly 6. Each set of movable buckle assembly 7 includes a horizontally arranged hollow column 701, a third compression spring 702 inside the hollow column 701, a movable buckle 703 at one end of the hollow column 701, and a connecting arm 704 inclined upward at the other end of the hollow column 701. One end of the connecting arm 704 is connected to the hollow column 701, and the other end of the connecting arm 704 is connected to the force transmission block 602.

[0052] The hollow column 701 has a second upper roller 705 and a second lower roller 706 on the upper and lower sides of one end near the movable buckle 703, respectively. The second upper roller 705 is placed in the groove of the precast concrete trough, and the second lower roller 706 is placed in the groove of the telescopic mechanism 9.

[0053] The fixing buckle 8 is located on the inner wall of the cast iron 10 of the precast concrete trough 14.

[0054] In this embodiment, the movable latch assembly 7 is similar to a door lock pin. One end of the hollow column 701 is equipped with rollers on both the upper and lower sides and placed in corresponding grooves. The other right end is hinged to the force transmission block 602 of the force transmission arm assembly 6 via a connecting arm 704. A third compression spring 702 passes through the hollow column 701. When the left end of the aforementioned rotating shaft lever 501 is low and the right end is high, the force transmission arm assembly 6 is subjected to force, and the two sets of movable latch assemblies 7 move accordingly, causing the movable latch 703 to disengage from the fixed latch 8. When the force is removed, the third compression spring 702 returns to its original position, causing the movable latch 703 to engage with the fixed latch 8.

[0055] Specifically, refer to Figure 8 The telescopic mechanism 9 includes an upper support plate 901, a lower support plate 902, and a first link assembly and a second link assembly disposed between the upper support plate 901 and the lower support plate 902. The first link assembly and the second link assembly are symmetrically arranged left and right. A fourth left compression spring 903 and a fourth right compression spring 904 are respectively provided at the left and right ends between the upper support plate 901 and the lower support plate 902. The upper and lower ends of the fourth left compression spring 903 and the fourth right compression spring 904 are respectively connected to the upper support plate 901 and the lower support plate 902.

[0056] Specifically, the first linkage assembly includes a first linkage 905, a second linkage 906, and a third linkage 907. One end of the first linkage 905 is connected to the upper end of the fourth left compression spring 903, and the other end of the first linkage 905 is connected to both the second linkage 906 and the third linkage 907. The end of the third linkage 907 is connected to the lower end of the fourth left compression spring 903. The second linkage assembly includes a fourth linkage 908, a fifth linkage 909, and a sixth linkage 91. 0. One end of the fourth link 908 is connected to the lower end of the fourth right compression spring 904. The other end of the fourth link 908 is connected to the fifth link 909 and the sixth link 910 respectively. The fifth link 909 is connected to the middle part of the third link 907. One end of the sixth link 910 is connected to the fourth link 908. The other end of the sixth link 910 is connected to the upper end of the fourth right compression spring 904. The middle part of the sixth link 910 is connected to the second link 906.

[0057] In this embodiment, the upper support plate 901 supports the upper force transmission arm assembly 6 and the movable buckle assembly 7; the lower support plate 902 is fixedly connected to the precast concrete trough 14 by a fixing pin; at the same time, the fourth left compression spring 903 and the fourth right compression spring 904, as well as the first link assembly and the second link assembly cooperate with each other to facilitate the completion of the force application and achieve the reset.

[0058] The working process of this invention: Refer to Figures 10-11 The one-way speed bump is placed between the solid and dashed lines. When changing lanes normally according to traffic rules, the trigger device 4 will not be activated, allowing vehicles to pass smoothly through the warning speed bump for overtaking or left turns. When crossing the solid line against traffic rules, the trigger device 4 is activated, transmitting force downwards. This causes the left end of the rotating shaft lever 501 of the spring-loaded force transmission lever assembly 5 to tilt downwards. Utilizing the lever principle, the right end of the rotating shaft lever 501 pulls the force transmission arm assembly 6 upwards. The force transmission block 602 drives the connecting arms 704 on both sides, causing the hollow columns 701 and movable buckles 703 on both sides to retract inwards within the grooves along with the pulleys on both sides. This causes the movable buckles 703 on both sides to disengage from the fixed buckles 8. At this time, under the influence of the wheel's gravity, the retractable speed bump 3 will retract and descend with the telescopic mechanism 9, resulting in an incomplete warning speed bump. The wheel is blocked by the fixed speed bump 1 and cannot pass smoothly, hindering the vehicle's illegal lane-changing behavior. After the wheel stops working, the retractable speed reduction block 3 returns to its original position under the action of various compression springs.

Pin sleeves 15 are pre-installed within the precast concrete trough 14. After the individual precast concrete troughs are fabricated, they are transported to the designated location for installation.

[0061] Step 2: Excavating and Cutting Strip-Shaped Foundation Trenches: First, measure and locate the strip-shaped foundation trench to be excavated between the solid and dashed lines; the width of the strip-shaped foundation trench should be 10-20mm wider and the depth should be 10-20mm deeper than the precast concrete trench; then, use a cutting machine to cut the road surface to its full thickness, strictly controlling the depth during cutting to avoid damaging the base layer; after cutting, road surface fragments should be collected and properly disposed of, and it is strictly forbidden to discard them at will; finally, compact the road base layer and spread dry-mixed mortar with a water-cement ratio of 0.2 as a leveling layer, with the spreading thickness controlled within 20mm;

[0062] Step 3: Install warning and deceleration devices for illegal lane changes: Arrange 10 warning and deceleration devices at intervals in a unit. First, lay a layer of cast iron waterproof layer on the precast concrete trough, and then fix each telescopic mechanism to the precast concrete trough with pins; finally, position and install the telescopic deceleration block and the telescopic mechanism.

[0063] Step 4: Install the warning and deceleration device for illegal lane changes: According to the positioning lines, vertically place the assembled warning and deceleration device for illegal lane changes into the road surface groove.

[0064] Step 5: Filling road gaps: After the warning and deceleration devices for illegal lane changes are installed, single-sized crushed stone of the same width as the gap is squeezed into the joint between the road surface and the precast concrete trough to improve the interlocking force between the road panels and enhance the load transfer performance.

[0065] In summary, this invention prevents vehicles from illegally crossing solid lines by using an incomplete one-way deceleration device, effectively preventing illegal lane changes, reducing accidents, and ensuring driving safety. It provides good guidance for correct lane changes, preventing vehicles from illegally changing lanes, but does not affect vehicles' normal lane-changing behavior according to the marked lines, thereby ensuring orderly traffic and reducing accidents.
