Detailed implementation mode

[0039] The following further elaborates on the above and other technical features and advantages of the present invention in conjunction with the accompanying drawings.

[0040] As Figures 1 to 15As shown in the figure, an embodiment of the present invention provides a pedestrian crossing warning device, which includes a traffic light pole 1. On one side of the traffic light pole 1, there is a support block 3. On both sides of the support block 3, symmetrically arranged ground-embedded boxes 31 are fixedly connected. The support block 3 and the ground-embedded boxes 31 are both buried underground, and their tops are just flush with the bottom surface where they are buried. The top of the support block 3 is fixedly connected with a pedal unit 2. The pedal unit 2 is installed at the crossing of the pedestrian crossing. Therefore, pedestrians who need to cross the road through the sidewalk must pass through the pedal unit 2. By cooperating the pedal unit 2 with the stepping detection structure 5, it is detected whether there are pedestrians on the pedal unit 2 during the red light period, and then voice reminders are given to the pedestrians waiting to cross the road. An inner box groove 311 is opened in the ground-embedded box 31. The inner box groove 311 is used to provide an installation space for the stepping detection structure 5 and at the same time adapt to the pedestrian pedal 22 on the pedal unit 2, so that when a pedestrian stands on the pedestrian pedal 22, the pedestrian pedal 22 can move downward; at the top of one side of the traffic light pole 1, there is a traffic light 11. On the side of the traffic light pole 1 close to the traffic light 11, there is a scrolling screen 12. The scrolling screen 12 is used for scrolling subtitles to remind pedestrians of festival safety. At the bottom of one side of the traffic light pole 1, there is a reminder speaker 13. The reminder speaker 13 is used to broadcast pedestrian crossing safety content.

[0041] The pedal unit 2 is composed of a deceleration support plate 21 and two pedestrian pedals 22 connected. On both sides of the deceleration support plate 21, pedestrian pedals 22 are fixedly connected. The deceleration support plate 21 is used to provide an installation position for the adjustment structure 4, and the pedestrian pedals 22 are used to provide a standing position for pedestrians. The length of the pedestrian pedal 22 is 1M, and the distance that a pedestrian walks in one step is 0.7M. The 1M-long pedestrian pedal 22 can ensure that pedestrians passing above it can be detected, avoiding the situation where pedestrians cross over the pedestrian pedal 22 and the pedestrians waiting to cross the road fail to be reminded. The shape of the pedestrian pedal 22 is adapted to the inner box groove 311. Therefore, when a pedestrian stands on the pedestrian pedal 22, one end of the pedestrian pedal 22 can slightly sink in the inner box groove 311, so that the stepping detection structure 5 can detect whether there are new pedestrians.

[0042] The bottom of the inner box groove 311 is connected with a stepping detection structure 5. The stepping detection structure 5 is used to detect whether there is a pedestrian stepping on the pedestrian pedal 22. At the same time, when a pedestrian steps on the pedestrian pedal 22, the stepping detection structure 5 can make the pedal unit 2 slowly descend, preventing pedestrians from suddenly descending and losing speed, effectively protecting the standing safety of pedestrians. At the same time, when a pedestrian leaves the pedestrian pedal 22, the stepping detection structure 5 can drive the pedestrian pedal 22 back to the initial position.

[0043] The top of the deceleration support plate 21 is connected with an adjustment structure 4, and the adjustment structure 4 is used to adjust the speed of pedestrians crossing the street, avoid running, so that all pedestrians will pass through the pedestrian pedal 22. The adjustment structure 4 includes an action belt 41 fixedly connected to the top of the deceleration support plate 21. An elastic support sheet 42 is slidably connected inside the action belt 41. The elastic support sheet 42 is used to support the action belt 41, so that its top has sufficient support strength. At the same time, when a bicycle or a wheelchair needs to pass, it can assist in reducing the passing difficulty of the action belt 41; it also includes a connection structure for connecting the in-ground box 31 and the pedestrian pedal 22.

[0044] As Figures 2 to 4 shown, the stepping detection structure 5 includes a buffer box 51 and a return box 52 fixedly connected to both sides of the bottom of the inner groove 311 of the box. When a pedestrian steps on the pedestrian pedal 22, the buffer box 51 can buffer the pedestrian pedal 22 and make it slowly descend. The buffer box 51 is filled with hydraulic oil. Both the buffer box 51 and the return box 52 are square structures with hollow interiors. The buffer box 51 and the return box 52 are connected by a return pipe 54 and two buffer pipes 55. The return pipe 54 and the buffer pipes 55 are used to realize the back-and-forth flow of hydraulic oil inside the buffer box 51 and the return box 52. A stepping pressing unit 53 is connected to the buffer box 51. The stepping pressing unit 53 includes a buffer slider 531 slidably connected to the inner wall of the buffer box 51. The top of the buffer slider 531 is fixedly connected with a connecting sliding column 532. A connecting sliding groove adapted to the connecting sliding column 532 is opened at the top of the buffer box 51. The connecting sliding column 532 penetrates through the top of the buffer box 51 and is fixedly connected with a pressing plate 533. The top of the pressing plate 533 is fixed to the end of the pedestrian pedal 22 away from the deceleration support plate 21. The stepping pressing unit 53 is used to cooperate with the pedestrian pedal 22. When a pedestrian stands on the pedestrian pedal 22, the weight of the pedestrian himself will drive the pedestrian pedal 22 to displace towards the buffer box 51. At this time, the pedestrian pedal 22 will drive the buffer slider 531 on the connecting sliding column 532 to slide inside the buffer box 51, so that the hydraulic oil inside the buffer box 51 is introduced into the return box 52 through the buffer pipe 55 by the extrusion of the buffer slider 531. The pedestrian pedal 22 is buffered by the slow passage of the hydraulic oil until the entire connecting sliding column 532 slides into the buffer box 51. At this time, the displacement distance of the pedestrian pedal 22 is the largest; one-way valves 56 are installed at one end of the return pipe 54 close to the buffer box 51 and at one end of the two buffer pipes 55 close to the return box 52. The one-way valves 56 make the return pipe 54 and the buffer pipes 55 can only pass in one direction.

[0045] Inside the return box 52, an extrusion unit and a power connection unit are connected. The extrusion unit includes a return slider 521 slidably connected to the inner wall of the return box 52. Both the return slider 521 and the buffer slider 531 are in an I-shaped structure. At both ends of one side of the return slider 521, a return spring 523 is fixedly connected. The ends of the two return springs 523 away from the return slider 521 are fixedly connected to the inner wall of the return box 52. When a pedestrian steps off the pedestrian pedal 22, there is no external force squeezing the pedestrian pedal 22. The return spring 523 squeezes the return slider 521 under the action of its own restoring deformation, and squeezes the hydraulic oil inside the return box 52 through the return slider 521, so that the hydraulic oil returns to the buffer box 51 through the return pipe 54. The hydraulic oil returning to the buffer box 51 will squeeze the buffer slider 531 to rise, so as to drive the pedestrian pedal 22 to return to the initial position through the stepping and pressing unit 53.

[0046] As Figure 4 and Figure 5As shown, the power connection unit includes an elastic power connection component 9 connected to the inner wall of the return box 52, and a first power connection piece 522 is fixedly connected to one side of the return slider 521, and the first power connection piece 522 is electrically connected to the main board inside the traffic light pole 1; the elastic power connection component 9 includes a first elastic strip 92 and a second elastic strip 93 fixedly connected to the inner wall of the return box 52 away from the return slider 521 and symmetrically distributed. When the return slider 521 is squeezed by the hydraulic oil and displaced toward the elastic power connection component 9 until it contacts the power connection support block 91, the first power connection piece 522 and the second power connection piece 94 on the power connection support block 91 fit each other, so that the detection circuit is closed and the main board is connected. The information of circuit closing and disconnection is used to determine whether there is a pedestrian on the pedestrian pedal 22. The first elastic strip 92 and the second elastic strip 93 are both concave arc structures. When the reflux slider 521 squeezes the power connection support block 91, the first elastic strip 92 and the second elastic strip 93 provide sufficient buffer space for the power connection support block 91. At the same time, the first elastic strip 92 and the second elastic strip 93 provide support for the power connection support block 91, so that when the second power connection sheet 94 on the power connection support block 91 is fitted with the first power connection sheet 522, the circuit will not be disconnected. The first elastic strip 92 and the second elastic strip 93 are fixedly connected to the power connection support block 91 on the same side end, and one side of the power connection support block 91 is fixedly connected There is a second power connection sheet 94 corresponding to the position of the first power connection sheet 522, the second power connection sheet 94 is electrically connected to the main board inside the traffic light pole 1, and at the same time forms a complete circuit with the first power connection sheet 522; the first elastic strip 92 and the second elastic strip 93 are provided with a matching elastic strip slot 95 at the corresponding position, when the first elastic strip 92 and the second elastic strip 93 are squeezed and deformed to a large extent, they can be staggered through the elastic strip slot 95, thereby increasing the displacement distance of the power connection support block 91, and the second elastic strip 93 is fixedly connected to one side of the second elastic strip 93 close to the first elastic strip 92 with two mutually symmetrical inward-turned strips 931, and one side of the first elastic strip 92 corresponds to the inward-turned strip 931. There are two symmetrical outward-turned strips 921 fixedly connected in position, and the inward-turned strip 931 is an arc-shaped structure with an inward concave shape. The outward-turned strip 921 is an arc-shaped structure with an outward-turned shape. When the power connection support block 91 continues to squeeze the first elastic strip 92 and the second elastic strip 93, the first elastic strip 92 and the second elastic strip 93, when the second elastic strip 93 is inserted into the elastic strip slot 95, the inward-turned strip 931 on the second elastic strip 93 will slide into the elastic strip slot 95 along the guidance of the outward-turned strip 921, avoiding the first elastic strip 92 and the second elastic strip 93 from pressing against each other when being squeezed and deformed, resulting in the power connection support block 91 no longer being offset, and thus being squeezed and damaged by the return slider 521.

[0047] like Figure 2 and Figures 6 to 12As shown, the connection structure includes an insertion unit 7 connected to a corner of the pedestrian pedal 22 away from the deceleration support plate 21. A locking unit 6 is connected to a position corresponding to the insertion unit 7 at the bottom of the inner box groove 311. A cover unit 8 is connected to a position corresponding to the insertion unit 7 on one side surface of the pedestrian pedal 22. The insertion unit 7, the locking unit 6, and the cover unit 8 cooperate with each other to lock the pedestrian pedal 22 to the ground-embedded box 31, while not affecting the offset of the pedestrian pedal 22 on the ground-embedded box 31. The locking unit 6 includes an L-shaped support block 61 fixedly connected to the bottom and side wall of the inner box groove 311. The L-shaped support block 61 is a support shell. A cylindrical groove 63 is opened at the top of the L-shaped support block 61. An annular concave locking restriction groove 64 is opened on the inner wall of the top of the cylindrical groove 63. Three locking balls 62 are arranged in an annular and evenly distributed manner on the locking restriction groove 64. The three locking balls 62 are stuck in the locking restriction groove 64 and are mutually extruded, so that the three locking balls 62 will not fall off; a conical pressing groove 221 is opened on the pedestrian pedal 22. The pressing groove 221 is used for installing the cover unit 8. An installation hole 223 penetrating the pedestrian pedal 22 is opened at the bottom of the pressing groove 221. The installation hole 223 is used for installing the insertion unit 7, so that the cover unit 8 can form a cooperation with the insertion unit 7 in the pressing groove 221. An annular limit card slot 222 is opened on the inner wall of the pressing groove 221. The cover unit 8 and the pedestrian pedal 22 are detachably connected through the limit card slot 222.

[0048] The insertion unit 7 includes an insertion rod 71 fixedly connected to the inner wall of the mounting hole 223. The insertion rod 71 is a tubular structure with one end open. An active rod 73 is arranged inside the insertion rod 71. The top end of the active rod 73 penetrates through the mounting hole 223 and extends into the pressing groove 221. A plurality of annularly distributed storage grooves 711 are formed in the inner wall of the bottom end of the insertion rod 71. A locking block 72 is rotatably connected to the top of the storage groove 711. A first connecting rod 731 is rotatably connected to the bottom of one side of the locking block 72. A second connecting rod 732 is rotatably connected to the top end inner wall of the insertion rod 71. A torsion spring is sleeved on the end of the second connecting rod 732 close to the inner wall of the insertion rod 71. The two ends of the torsion spring are respectively in contact with the inner wall of the insertion rod 71 and the second connecting rod 732. One ends of the second connecting rod 732 and the first connecting rod 731 are respectively rotatably connected to the outer surface of the active rod 73. The outer side of the locking block 72 is adapted to the outer wall of the locking ball 62. When the three locking balls 62 are in contact with the inner wall of the locking limiting groove 64, the insertion unit 7 can just be inserted into the gap between the three locking balls 62. When the insertion unit 7 is inserted into the locking unit 6, in the initial state, the active rod 73 moves towards the top of the insertion rod 71 driven by the second connecting rod 732. The active rod 73 drives the first connecting rod 731 under the drive of the second connecting rod 732, so as to drive the locking block 72 to rotate towards the inside of the insertion rod 71 along the storage groove 711 through the first connecting rod 731, so as to receive a plurality of locking blocks 72 inside the insertion rod 71. Then the insertion rod 71 is inserted into the gap between the three locking balls 62. Then, by pressing the active rod 73 to push the first connecting rod 731, the locking block 72 is pushed out, and the insertion rod 71 is locked by the locking block 72, so that it is restricted below the locking ball 62, and at the same time, it does not affect the downward movement of the insertion rod 71.

[0049] The cover unit 8 includes a cover plate 85 connected to the pressing groove 221. A pressing hole 82 is formed in the bottom of the cover plate 85. A pressing locking rod 83 is fixedly connected to the position corresponding to the top end of the pressing hole 82 and the active rod 73. An insertion ring 81 adapted to it is fixedly connected to the position corresponding to the limiting card slot 222 on the surface of the cover plate 85. An annular buckle 84 is fixedly connected to one side of the insertion ring 81. An annular groove adapted to the annular buckle 84 is formed in the limiting card slot 222. The cover plate 85 is fixed on the pedestrian pedal 22 through the cooperation of the annular buckle 84 and the annular groove. When installing the cover unit 8, the insertion ring 81 on the cover plate 85 is inserted into the limiting card slot 222, and the active rod 73 is extruded through the pressing locking rod 83, so that the active rod 73 is always in the state of pushing out the locking block 72, so as to cooperate with the plugging unit to lock with the locking unit 6.

[0050] Such as Figure 1 , Figure 2 , Figure 13 And Figure 14As shown, an embedding groove 412 is formed inside the acting belt 41. The top of the acting belt 41 is made of rubber, and its thickness gradually changes from thick in the middle to thin towards both sides. The embedding groove 412 is used to provide an installation position for the elastic support piece 42; the elastic support piece 42 is formed by connecting a third elastic section 423, two fourth elastic sections 424, two second elastic sections 422, and two first elastic sections 421; the two fourth elastic sections 424 are symmetrically distributed on the concave side of the third elastic section 423. One end of each of the two fourth elastic sections 424 far from the third elastic section 423 is fixedly connected with a first sliding bar 425. The outer turning sides of the two second elastic sections 422 are respectively fixedly connected to both ends of the third elastic section 423. Both ends of the second elastic section 422 are respectively fixedly connected with a second sliding bar 426 and a fourth sliding bar 428. The concave sides of the two second elastic sections 422 are both fixedly connected with a first elastic section 421. One end of each of the two first elastic sections 421 far from the second elastic section 422 is fixedly connected with a third sliding bar 427; the inner wall of the embedding groove 412 is provided with sliding bar chutes 413 adapted to the first sliding bar 425, the second sliding bar 426, the third sliding bar 427, and the fourth sliding bar 428. Both ends of the acting belt 41 are detachable, so that the embedding groove 412 is exposed. The elastic support piece 42 can be directly slid into the acting belt 41 through the sliding bar chutes 413, which is convenient for replacing the elastic support piece 42.

[0051] When a bicycle or a wheelchair needs to pass through the acting belt 41, when the wheel presses on the edge position of the acting belt 41, the first elastic section 421 will be squeezed. Since the first elastic section 421 is an outwardly convex arc structure, when the first elastic section 421 is subjected to an external force, it will bend and extend towards both sides, and the bottom end of the first elastic section 421 is limited and fixed by the third sliding bar 427. Therefore, the deformation acting force of the first elastic section 421 will squeeze the top part of the second elastic section 422, squeezing the second elastic section 422 to bend and deform towards the outer convex side. At the same time, the top of the acting belt 41 deviates towards the inside of the embedding groove 412 under the drive of the bending of the second elastic section 422, so that the inclination of the uphill section of the acting belt 41 is reduced, making it more convenient for bicycle or wheelchair users to pass. After passing, under the elastic force of the fourth elastic section 424 and the third elastic section 423, the acting belt 41 returns to its initial state. When a pedestrian passes, the acting force of the foot acts vertically on the top of the acting belt 41. With the support of the fourth elastic section 424 and the third elastic section 423, it is also strong enough to prevent the acting belt 41 from deforming or deforming slightly, without affecting the pedestrian.

[0052] The present application also provides a warning method for a pedestrian crossing warning device, including the following steps:

[0053] S1. During installation, first dig a pit beside the traffic light pole 1 that is adapted to the support block 3 and the ground-embedded box 31, and then place the support block 3 and the ground-embedded box 31 into it for fixation;

[0054] S2. Install the pedestrian pedal 22 on the pedal unit 2 on the ground-embedded box 31 through the insertion unit 7 and the locking unit 6, and then lock the insertion unit 7 and the locking unit 6 through the capping unit 8;

[0055] S3. Detect in real time whether there are pedestrians passing or standing through the pedestrian pedal 22 and the stepping detection structure 5, and warn pedestrians through the scrolling screen 12 and the prompting sound 13 according to the real-time situation of the traffic light 11.

[0056] The working principle of the technical solution provided by the present invention is as follows: During operation, the main board inside the traffic light pole 1 judges whether the traffic light 11 is red or green. When it is red, it judges whether there are pedestrians at the crosswalk. When there are no pedestrians, the scrolling screen 12 and the prompting sound 13 are turned off to save power resources. When there are pedestrians staying, the scrolling screen 12 is turned off and the prompting sound 13 is turned on to remind pedestrians not to run a red light. When the traffic light 11 is green, it detects whether there are pedestrians at the crosswalk. When there are no pedestrians, the prompting sound 13 is turned off and the scrolling screen 12 is turned on to remind pedestrians at the oncoming intersection. When it is detected that there are pedestrians staying, the scrolling screen 12 and the broadcast sound are turned on.

[0057] During installation, first dig a pit beside the traffic light pole 1 that is adapted to the support block 3 and the ground-embedded box 31, then place the support block 3 and the ground-embedded box 31 in place and fix them. Fix the pedal unit 2 on the support block 3 so that the pedestrian pedal 22 on the pedal unit 2 is stuck on the inner groove 311 of the box. When the insertion unit 7 is inserted into the locking unit 6, in the initial state, the movable rod 73 moves towards the top of the insertion rod 71 driven by the second connecting rod 732. The movable rod 73 drives the first connecting rod 731 under the drive of the second connecting rod 732, so as to drive the locking block 72 to rotate along the receiving groove 711 into the insertion rod 71 through the first connecting rod 731, thereby receiving several locking blocks 72 inside the insertion rod 71. Then insert the insertion rod 71 into the gap between the three locking balls 62, and then push the first connecting rod 731 by pressing the movable rod 73 to push out the locking block 72, and lock the insertion rod 71 through the locking block 72 so that it is restricted below the locking balls 62. Then fix the cover plate 85 on the pedestrian pedal 22 through the cooperation of the annular buckle 84 and the annular groove. When installing the capping unit 8, insert the insertion ring 81 on the cover plate 85 into the limit card slot 222, and press the locking rod 83 to squeeze the movable rod 73, so that the movable rod 73 is always in the state of pushing out the locking block 72, thereby cooperating with the insertion unit to lock with the locking unit 6. At the same time, connect the connection position between the pedestrian pedal 22 and the ground-embedded box 31 with an elastic rubber strip, and finally fix the adjustment structure 4 on the deceleration support plate 21.

[0058] When there is a pedestrian on the pedestrian pedal 22, when the pedestrian stands on the pedestrian pedal 22, the weight of the pedestrian himself will drive the pedestrian pedal 22 to displace towards the buffer box 51. At this time, the pedestrian pedal 22 will drive the buffer slider 531 on the connecting sliding column 532 to slide inside the buffer box 51, so that the hydraulic oil inside the buffer box 51 is introduced into the return box 52 through the buffer pipe 55 by the extrusion of the buffer slider 531. The slow passage of the hydraulic oil buffers the pedestrian pedal 22 until the entire connecting sliding column 532 slides into the buffer box 51. At the same time, the return slider 521 displaces towards the elastic power connection component 9 under the extrusion of the hydraulic oil until it contacts the power connection support block 91. At this time, the first power connection piece 522 and the second power connection piece 94 on the power connection support block 91 are mutually attached, so that the detection circuit is closed. The main board judges whether there is a pedestrian on the pedestrian pedal 22 based on the information of the circuit closing and opening.

[0059] When the pedestrian walks off the pedestrian pedal 22, there is no external force squeezing the pedestrian pedal 22. The return spring 523 squeezes the return slider 521 under the action of its own restored deformation. The hydraulic oil inside the return box 52 is squeezed by the return slider 521, so that the hydraulic oil flows back into the buffer box 51 through the return pipe 54. The hydraulic oil flowing back into the buffer box 51 will squeeze the buffer slider 531 to rise, so that the pedestrian pedal 22 is driven by the stepping and pressing unit 53 to return to the initial position.

[0060] The above is only the preferred embodiment of the present invention, which is illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
