Description

Technical Field

[0001] This application relates to the field of road traffic facility technology, and in particular to a road structure that separates pedestrians and vehicles. Background Technology

[0002] In urban transportation planning and construction projects, separating pedestrians and vehicles is an important means to improve road traffic efficiency and ensure pedestrian safety.

[0003] In existing technologies, pedestrian-vehicle separation structures use barriers or landscaping (green belts) to separate motor vehicle lanes and non-motor vehicle lanes. Obstacles are placed at both ends of the non-motor vehicle lanes to prevent vehicles from entering them, while leaving space for pedestrians to pass.

[0004] While existing technologies can provide some separation for the aforementioned issues, their fixed positions in narrow roads prevent them from flexibly adjusting to changes in traffic flow, potentially leading to a waste of road resources at certain times. Furthermore, the abnormal driving of some vehicles within the lanes can easily cause traffic congestion, a problem that existing technologies also cannot solve. Summary of the Invention

[0005] To address the lack of flexibility in adjusting pedestrian-vehicle separation road space in existing technologies, this application provides a pedestrian-vehicle separation road structure.

[0006] The following technical solution is adopted: A pedestrian-vehicle separation road structure includes a median strip, a first drive assembly, a mounting base, and a plurality of bollards; the median strip separates a motor vehicle lane from a non-motor vehicle lane; the mounting base is located at both ends of the non-motor vehicle lane; the plurality of bollards are divided into two groups, with each group of bollards spaced apart on a corresponding mounting base; the first drive assembly drives the median strip to translate, and the mounting base is provided with a second drive assembly that drives the bollards to move to make way for the median strip.

[0007] By adopting the above technical solution, when encountering situations such as rush hour traffic or congestion caused by vehicles changing lanes, cutting in, or making U-turns, the median strip is driven to move horizontally, thereby widening the lanes. Simultaneously, the second drive component moves the obstacle posts, thus making way for the movement of the median strip. In this way, a road structure that ensures effective separation of pedestrians and vehicles while allowing for flexible adjustments as needed is provided, thereby increasing vehicle traffic efficiency.

[0008] Optionally, the mounting base is provided with a slide rail, the slide rail including a sliding section and a yielding section, the sliding section being arranged perpendicular to the length direction of the non-motorized vehicle lane, the yielding section being connected to the end of the sliding section, and the yielding section being arranged at an angle to the sliding section; the second driving assembly includes a sliding seat and a yielding seat, each set of obstacle posts being respectively connected to the corresponding sliding seat and the yielding seat; the sliding seat is slidably connected in the sliding section, and the yielding seat is slidably connected in the yielding section; the second driving assembly further includes a sliding driving component for driving the sliding seat to move, and a yielding driving component for driving the yielding seat to move.

[0009] By adopting the above technical solution, the bollards achieve at least three effects: First, the yielding seat causes several bollards to slide along the yielding section, creating sufficient space for the safety barrier. Second, when people, such as strollers or wheelchairs, have difficulty passing through, the yielding seat moves, increasing the distance between the bollards along the edge of the yielding seat and the bollards along the edge of the sliding seat, thus facilitating passage. Third, the distance between the bollards remains constant, preventing motor vehicles from forcibly squeezing into the non-motorized vehicle lane.

[0010] Optionally, the isolation strip includes a plurality of spaced-apart connecting columns; adjacent connecting columns are connected by connecting beams, and the connecting beams are hinged to the connecting columns; a sliding platform is provided at the bottom of each connecting column; the first driving assembly includes a traction rod and a plurality of rollers; the plurality of rollers are rotatably connected to the bottom of the corresponding sliding platform, and a balancing motor for driving the rollers to rotate is provided in each of the plurality of sliding platforms; the connecting column located on the mounting base has a guide rod at its bottom; the guide rod extends into the slide rail, and the guide rod is connected to the sliding base through the traction rod.

[0011] By adopting the above technical solution, the connecting beam and connecting column are hinged, allowing the isolation zone to form a curve. Two of the connecting columns move simultaneously with the obstacle piles, while the remaining sliding platforms move via several rollers, thereby maintaining the balance of the connecting columns during movement.

[0012] Optionally, the sliding drive component includes a screw and a first drive motor; the screw is rotatably connected to the mounting base along the length of the sliding section, and the first drive motor drives the screw to rotate; a boss is provided at the bottom of the sliding seat, the screw passes through the boss and is threadedly connected to the boss.

[0013] Optionally, the clearance driving component includes teeth, a gear, and a second drive motor; the teeth are disposed on the inner wall along the length direction of the clearance segment, the gear is rotatably connected to one end of the clearance seat, the second drive motor is disposed in the clearance seat to drive the gear to rotate, and the gear meshes with the teeth; the screw and the teeth are in different planes.

[0014] Optionally, the yielding section is arc-shaped; the yielding seat includes a plurality of node blocks and a flexible chain, the plurality of node blocks are spaced apart, the plurality of node blocks are connected to each other by the flexible chain, the obstacle post is connected to the node blocks, and the node blocks at both ends are provided with a second drive motor and a gear; a guide post is provided on the side of the node block away from the teeth; a limit ball is provided at the end of the guide post, and a limit groove is opened on the inner wall of the yielding section for the limit ball to slide, the cross-sectional shape of the limit groove corresponds to the limit ball.

[0015] By adopting the above technical solution, the seat adopts a flexible structure and the drive source is set at the front and rear. The entire seat can be moved by dragging the front end or by dragging the rear end.

[0016] Optionally, the flexible chain includes a main chain block and a secondary chain block, the node block is rotatably connected to the secondary chain block, one end of the secondary chain block is rotatably connected to the main chain block, and the other end is rotatably connected to the node block.

[0017] Optionally, the bottom of the obstacle column is arrayed with a number of ball bearings that are rotatably connected, and the surface of the mounting base is provided with a slide for the ball bearings to roll.

[0018] By adopting the above technical solution, the ball bearings are used to support the movement of the obstacle column.

[0019] Optionally, the obstacle post is equipped with a flashing warning light that appears before the obstacle post moves.

[0020] By adopting the above technical solution, the warning lights will flash before and during the movement of the obstacle post to remind pedestrians in the vicinity to avoid it.

[0021] Optionally, the mounting base has a plurality of vertically formed sinkholes, and the obstacle pile is slidably connected to the sinkholes; the mounting base is provided with a third driving component that drives the obstacle pile to enter or exit the sinkholes.

[0022] By adopting the above technical solution, the obstacle pile is moved by sinking or moving upwards within the sinkhole. The effect after movement is the same as that of the aforementioned translation method.

[0023] In summary, this application includes at least one of the following beneficial effects: 1. By shifting the median strip, the lanes are widened, providing a road structure that can both ensure the separation of pedestrians and vehicles and can be flexibly adjusted as needed to increase vehicle traffic efficiency; 2. When people have difficulty passing through due to situations such as strollers or wheelchairs, the seat can be moved to increase the distance between the obstacle posts on the edge of the seat and the obstacle posts on the edge of the sliding seat, thereby facilitating the passage of people.

[0026] The following is in conjunction with the appendix Figure 1 To be continued Figure 8 This application will be described in further detail.

[0027] A pedestrian-vehicle separation road structure includes a median strip 1, a first drive assembly, mounting bases 3, and several bollards 4. The median strip 1 separates a motor vehicle lane 11 and a non-motor vehicle lane 12. The mounting bases 3 are located at both ends of the non-motor vehicle lane 12, with their upper surfaces flush with the ground. The bollards 4 are divided into two groups and located on their respective mounting bases 3, forming an effective barrier at the entrance of the non-motor vehicle lane 12 to prevent motor vehicles (especially electric bicycles) from entering. Space is left between the bollards 4 in each group for pedestrians to pass through. The first drive assembly drives the median strip 1 to move horizontally, and the mounting base 3 contains a second drive assembly that moves the bollards 4 to make way for the median strip 1. In situations such as rush hour traffic or congestion caused by lane changes, cutting in, or U-turns, the second drive assembly moves the bollards 4 to make way for the median strip 1. The median strip 1 is driven to move horizontally by the first drive assembly, thereby widening the lanes.

[0028] Furthermore, the isolation belt 1 includes several connecting posts 13 and several connecting beams 14. The connecting posts 13 are vertically spaced, and their bottoms are equipped with sliding platforms 15, which allows the isolation belt 1 to remain stable during movement. The connecting beams 14 are located between two adjacent connecting posts 13. Through hinged connections with the connecting posts 13, the connecting beams 14 can flexibly adjust their angles during the movement of the isolation belt 1 to adapt to the needs of different positions. The first drive assembly includes several rollers 21; the several rollers 21 are rotatably connected to the bottom of the corresponding sliding platforms 15, and the several sliding platforms 15 are equipped with balancing motors that drive the rollers 21 to rotate. Since the scheme of using balancing motors to drive the rollers 21 to rotate is prior art, it will not be described in detail here.

[0029] Example 1: Obstacle 4 moves in a horizontal direction.

[0030] Furthermore, the mounting base 3 is equipped with a slide rail 31. The slide rail 31 includes a sliding section 311 and a yielding section 312. The sliding section 311 is positioned perpendicular to the length of the non-motorized vehicle lane 12, with one end close to the initial position of the guardrail 1 and the other end extending outward. The yielding section 312 is connected to the end of the sliding section 311 away from the guardrail 1, and is angled to the sliding section 311, causing the yielding section 312 to extend in a direction deviating from the length of the sliding section 311. The second drive assembly includes a sliding seat 51 and a yielding seat 52, with the obstacle piles 4 in each group connected to the corresponding sliding seat 51 and yielding seat 52. For ease of distinction, the obstacle piles 4 installed on the sliding seat 51 are referred to as obstacle pile I 41, and the obstacle piles 4 installed on the yielding seat 52 are referred to as obstacle pile II 42. The top of the slide rail 31 is provided with a constriction, so that the internal cross-section of the slide rail 31 forms a convex structure. To prevent excessive external impurities from entering the slide rail 31, a drainage hole is provided at the bottom of the slide rail 31 to drain water into the soil. An obstacle pile 4 is installed on the surface of the mounting base 3, and a support rod 43 is provided at the bottom of the obstacle pile 4. Obstacle pile I 41 is connected to the sliding seat 51 via the support rod 43, and obstacle pile II 42 is connected to the yielding seat 52 via the support rod 43. The sliding seat 51 is slidably connected in the sliding section 311, and the yielding seat 52 is slidably connected in the yielding section 312. The yielding seat 52 can initially be positioned in the sliding section 311. The second drive assembly also includes a sliding drive component for driving the sliding seat 51 to move, and a yielding drive component for driving the yielding seat 52 to move. The bollards 4 have at least three effects: First, the yielding seat 52 drives several bollards 4 to slide along the yielding section 312, thus deviating from the length direction of the sliding section 311; the bollards 4 set on the sliding seat 51 move accordingly. This design allows the bollards 4 to turn via the yielding section 312 after moving to a certain position, thereby creating more space for the guardrail 1 to pass. Second, since the sliding seat 51 and the yielding seat 52 are set separately, when there are situations where it is inconvenient for people to pass, such as strollers or wheelchairs, the yielding seat 52 moves, increasing the distance between the bollards 4 on the edge of the yielding seat 52 and the bollards 4 on the edge of the sliding seat 51, thus facilitating the passage of people. Third, since the bollards 4 are fixed to the sliding seat 51 and the yielding seat 52, the distance between the bollards 4 is a constant value at the beginning and end of the movement, preventing motor vehicles from forcibly squeezing into the non-motorized vehicle lane 12 due to the excessive distance after the bollards 4 have moved.

[0031] Furthermore, the first drive assembly also includes a traction rod 22. A connecting column 13 located on the mounting base 3 has a guide rod 151 at its bottom. The guide rod 151 extends into the slide rail 31, and the traction rod 22 is located at the bottom of the guide rod 151. One end of the traction rod 22 is rotatably connected to the guide rod 151, and the other end is rotatably connected to the sliding seat 51. The connecting column 13, together with the connecting beam 14, forms a barrier to the lane. The connecting beam 14 is hinged to the connecting column 13, allowing the barrier strip 1 to form a curve, and the barrier strip 1 can move segment by segment during movement to prevent collisions caused by overall movement. The traction rod 22 allows two of the connecting columns 13 to move simultaneously with the obstacle posts 4 (the obstacle posts 4 at both ends of the non-motorized vehicle lane 12 do not move simultaneously), and the remaining sliding seats 15 have several rollers 21 at their bottom, which can move accordingly, thereby maintaining the balance of the connecting columns 13 during movement. This design allows the isolation belt 1 to move smoothly with the support of the rollers 21, while the balancing motor ensures that the isolation belt 1 remains horizontal during movement, preventing tilting or deviation.

[0032] Furthermore, the sliding drive component includes a screw 61 and a first drive motor 62. The screw 61 is rotatably connected to the mounting base 3 along the length of the sliding section 311, and the first drive motor 62 drives the screw 61 to rotate. A boss 511 is provided at the bottom of the sliding seat 51, through which the screw 61 passes and is threadedly connected to the boss 511. By driving the screw 61 to rotate through the first drive motor 62, the boss 511 threadedly connected to the screw 61 moves radially along the screw 61, thereby driving the sliding seat 51 to move within the slide rail 31.

[0033] Furthermore, the clearance driving component includes a tooth 71, a gear 72, and a second drive motor 73. The tooth 71 is disposed on the inner wall along the length of the clearance section 312. The gear 72 is rotatably connected to one end of the clearance seat 52. The second drive motor 73 is disposed in the clearance seat 52 and drives the gear 72 to rotate, with the gear 72 meshing with the tooth 71. The screw 61 and the tooth 71 are on different planes. The second drive motor 73 drives the gear 72 to rotate, and because the gear 72 meshes with the tooth 71, the gear 72 rolls relative to each other along the length of the clearance section 312. This causes the clearance seat 52 to slide within the clearance section 312. In addition, the mounting base 3 has a groove 32 for the screw 61 to rotate and the protrusion 511 to slide, and the groove 32 is arranged parallel to the sliding section 311. This ensures that the screw 61 and the tooth 71 are on different planes to prevent mutual interference.

[0034] Furthermore, the yielding section 312 is arc-shaped. The yielding seat 52 includes several node blocks 521 and flexible chains 522. The node blocks 521 are spaced apart and connected by flexible chains 522. The node blocks 521 have a near-circular structure. The obstacle post II 42 is connected to the node blocks 521. The node blocks 521 at both ends are equipped with a second drive motor 73 and a gear 72. A guide post 53 is provided on the side of the node block 521 away from the teeth 71. A limiting ball 531 is provided at the end of the guide post 53. A limiting groove 313 is opened on the inner wall of the yielding section 312 for the limiting ball 531 to slide. The cross-sectional shape of the limiting groove 313 corresponds to that of the limiting ball 531. The yielding section 312 is arc-shaped, which helps the yielding seat 52 to transition smoothly and allows for more movable space. To accommodate the curved relief section 312, the relief seat 52 adopts a flexible structure, with the drive source located at both ends. It can be moved by dragging the entire relief seat 52 from either the front or rear end. The engagement of the limiting ball 531 ensures that the gear 72 is always engaged with the teeth 71, preventing separation of the gear 72 from the teeth 71 during movement due to excessive relief clearance. This results in more stable movement of the relief block.

[0035] Furthermore, the flexible chain 522 includes a main chain block 5221 and a secondary chain block 5222. The node block 521 is rotatably connected to the secondary chain block 5222, and one end of the secondary chain block 5222 is rotatably connected to the main chain block 5221, while the other end is rotatably connected to the node block 521. Through the cooperation of the main chain block 5221 and the secondary chain block 5222, the flexible chain 522 can be bent to adapt to the arc-shaped clearance segment 312.

[0036] Furthermore, the bottom of the obstacle post is arrayed with several ball bearings 44 and rotatably connected thereto, and the surface of the mounting base 3 is provided with a slide for the ball bearings 44 to roll. The ball bearings 44 are used to support the movement of the obstacle post.

[0037] Furthermore, the bollard 4 is equipped with a flashing warning light that illuminates before it moves. The warning light flashes rapidly before and during the movement of the bollard 4 to alert pedestrians in the vicinity to avoid it.

[0038] The implementation principle of this embodiment is as follows: When encountering situations such as rush hour traffic or congestion caused by vehicles changing lanes, cutting in, or making U-turns, the second drive assembly moves the barrier post 4 to make way for the movement of the median strip 1. The median strip 1 is then driven to move horizontally by the first drive assembly, thereby widening the lane.

[0039] Example 2: Obstacle 4 moves in a vertical direction.

[0040] Furthermore, the mounting base 3 has several vertically formed sinkholes, and the obstacle piles 4 are slidably connected in these sinkholes. A third drive assembly is installed within the mounting base 3 to drive the obstacle piles 4 into or out of the sinkholes. The obstacle piles 4 move by sinking or rising within the sinkholes. When the obstacle pile sinks into the extended surface of the mounting base 3, the isolation strip 1 can move past the obstacle pile, thus enabling the isolation strip 1 to move. Simultaneously, the sinking of the obstacle piles 4 makes way for wheelchairs and strollers. The third drive assembly can be a hydraulic system, a pneumatic system, or other technologies, all of which can achieve this effect.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
