DETAILED DESCRIPTION

[0020] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 15 As shown, an embodiment of the present invention provides a pedestrian crossing warning device, including a traffic light pole 1, a support block 3 is provided on one side of the traffic light pole 1, and both sides of the support block 3 are fixedly connected to mutually symmetrically arranged ground-embedded boxes 31, the support block 3 and the ground-embedded boxes 31 are both buried underground, and the tops thereof are just flush with the horizontal height of the buried bottom surface, and the top of the support block 3 is fixedly connected to a pedal unit 2, which is installed at the intersection of the sidewalk, so pedestrians who need to cross the road through the sidewalk need to pass through the pedal unit 2, and the pedal unit 2 cooperates with the stepping detection structure 5 to detect whether there are pedestrians on the pedal unit during the red light period. 2, and then give voice reminders to pedestrians crossing the street. A box slot 311 is opened in the embedded box 31, and the box slot 311 is used to provide an installation space for the stepping detection structure 5, and at the same time adapts to the pedestrian pedal 22 on the pedal unit 2, so that when the pedestrian stands on the pedestrian pedal 22, the pedestrian pedal 22 can move downward; a traffic light 11 is provided at the top of one side of the traffic light pole 1, and a scrolling screen 12 is provided on the side of the traffic light pole 1 close to the traffic light 11. The scrolling screen 12 is used to scroll subtitles to remind newlyweds to celebrate the festival safely. A reminder sound 13 is provided at the bottom of one side of the traffic light pole 1, and the reminder sound 13 is used to broadcast pedestrian crossing safety content.

[0022] The pedal unit 2 is composed of a deceleration support plate 21 and two pedestrian pedals 22. The pedestrian pedals 22 are fixedly connected on both sides of the deceleration support plate 21. The deceleration support plate 21 is used to provide an installation position for the adjustment structure 4, and the pedestrian pedal 22 is used to provide a standing position for pedestrians. The length of the pedestrian pedal 22 is 1M, and the distance crossed by a pedestrian in one step is 0.7M. The 1M long pedestrian pedal 22 can ensure that pedestrians passing above it can be detected to avoid the situation where pedestrians cross the pedestrian pedal 22, resulting in the failure to remind pedestrians to cross the street. The shape of the pedestrian pedal 22 is adapted to the inner groove 311 of the box. Therefore, when a pedestrian stands on the pedestrian pedal 22, one end of the pedestrian pedal 22 can sink slightly in the inner groove 311 of the box, so that the stepping detection structure 5 can detect whether there is a new person.

[0023] The bottom of the inner groove 311 of the box is connected to a stepping detection structure 5, which 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, and will not let the pedestrian suddenly descend and stall, which can effectively protect the pedestrian's standing safety. At the same time, when the pedestrian leaves the pedestrian pedal 22, the stepping detection structure 5 can drive the pedestrian pedal 22 back to the initial position.

[0024] The top of the deceleration support plate 21 is connected to an adjustment structure 4, which is used to adjust the speed of pedestrians crossing the street to avoid running, so that all pedestrians can 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, and 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 the top of the action belt has sufficient supporting strength. At the same time, when a bicycle or wheelchair needs to pass, it can help reduce the difficulty of passing the action belt 41; it also includes a connecting structure for connecting the embedded box 31 and the pedestrian pedal 22.

[0025] like Figures 2 to 4 As shown, the stepping detection structure 5 includes a buffer box 51 and a reflux 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 to make it slowly descend. The buffer box 51 is filled with hydraulic oil. The buffer box 51 and the reflux box 52 are both square structures with hollow interiors. The buffer box 51 and the reflux box 52 are connected by a reflux pipe 54 and two buffer pipes 55. The reflux pipe 54 and the buffer pipe 55 are used to realize the hydraulic oil flowing back and forth inside the buffer box 51 and the reflux box 52. The buffer box 51 is connected to a stepping pressing unit 53. 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 to a connecting slide column 532. The top of the buffer box 51 is provided with a connecting slide groove adapted to the connecting slide column 532. The connecting slide column 532 passes through the top fixed connection of the buffer box 51 A pressing plate 533 is connected, and 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 pedestrian's own weight will drive the pedestrian pedal 22 to move toward the buffer box 51. At this time, the pedestrian pedal 22 will drive the buffer slider 531 on the connecting slide 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 through the squeezing of the buffer slider 531. The pedestrian pedal 22 is buffered by the slow passage of the hydraulic oil until the entire connecting slide column 532 slides into the buffer box 51. At this time, the displacement distance of the pedestrian pedal 22 is the maximum; a one-way valve 56 is installed at one end of the return pipe 54 close to the buffer box 51 and one end of the two buffer pipes 55 close to the return box 52. The one-way valve 56 allows the return pipe 54 and the buffer pipe 55 to only pass in one direction.

[0026] The reflux box 52 is internally connected with an extrusion unit and a power connection unit, and the extrusion unit includes a reflux slider 521 slidably connected to the inner wall of the reflux box 52, and the reflux slider 521 and the buffer slider 531 are both I-shaped structures, and return springs 523 are fixedly connected to both ends of one side of the reflux slider 521, and one end of the two return springs 523 away from the reflux slider 521 is fixedly connected to the inner wall of the reflux box 52. When a pedestrian walks on the pedestrian pedal 22, there is no external force to squeeze the pedestrian pedal 22. The return spring 523 squeezes the reflux slider 521 under the force of its own deformation recovery, and squeezes the hydraulic oil inside the reflux box 52 through the reflux slider 521, so that the hydraulic oil flows back to the buffer box 51 through the reflux pipe 54. The hydraulic oil flowing back to the buffer box 51 will squeeze the buffer slider 531 to rise, thereby driving the pedestrian pedal 22 to return to its initial position by stepping on the pressing unit 53.

[0027] like 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.

[0028] like Figure 2 and Figures 6 to 12As shown, the connection structure includes an insertion unit 7 connected to the corner of the pedestrian pedal 22 away from the deceleration support plate 21, a locking unit 6 is connected to the bottom of the box inner groove 311 at a position corresponding to the insertion unit 7, and a cover unit 8 is connected to the side surface of the pedestrian pedal 22 at a position corresponding to the insertion unit 7. The insertion unit 7, the locking unit 6 and the cover unit 8 cooperate with each other to lock the pedestrian pedal 22 with the embedded box 31, and do not affect the displacement of the pedestrian pedal 22 on the embedded box 31. The locking unit 6 includes an L-shaped support block 61 fixedly connected to the bottom and side wall of the box inner groove 311, the L-shaped support block 61 is a support shell, and a cylindrical groove 63 is opened on the top of the L-shaped support block 61, and an annular inner wall of the top of the cylindrical groove 63 is opened A concave locking limit groove 64 is provided with three locking balls 62 evenly distributed in a ring shape. The three locking balls 62 are stuck in the locking limit groove 64 and squeezed against each other, so that the three locking balls 62 will not fall off. A conical pressing groove 221 is provided on the pedestrian pedal 22, and the pressing groove 221 is used to install the cover unit 8. A mounting hole 223 that passes through the pedestrian pedal 22 is provided at the bottom of the pressing groove 221, and the mounting hole 223 is used to install the insertion unit 7, so that the cover unit 8 can cooperate with the insertion unit 7 in the pressing groove 221. An annular limiting groove 222 is provided on the inner wall of the pressing groove 221, and the cover unit 8 and the pedestrian pedal 22 are detachably connected through the limiting groove 222.

[0029] When the locking cam 72 is in the closed position, the locking cam 720 is in the closed position, and the locking cam 720 is in the closed position, so that the locking cam 720 can be locked. When the locking cam 72 is in the closed position, the locking cam 72 is pressed against the locking cam 73 and the locking cam 73 is pressed against the locking cam 73. When the locking cam 72 is in the closed position, the locking cam 72 is pressed against the locking cam 73 and the locking cam 73 is pressed against the locking cam 73.

[0030] The covering unit 8 includes a cover plate 85 connected to the pressing groove 221, a pressing hole 82 is provided at the bottom of the cover plate 85, a pressing locking rod 83 is fixedly connected to the top of the pressing hole 82 at a position corresponding to the movable rod 73, a plug ring 81 is fixedly connected to the surface wall of the cover plate 85 at a position corresponding to the limiting slot 222, an annular buckle 84 is fixedly connected to one side of the plug ring 81, an annular groove matching the annular buckle 84 is provided inside the limiting slot 222, the cover plate 85 is fixed to the pedestrian pedal 22 through the cooperation between the annular buckle 84 and the annular groove, when installing the covering unit 8, the plug ring 81 on the cover plate 85 is inserted into the limiting slot 222, and the movable rod 73 is squeezed by pressing the locking rod 83, so that the movable rod 73 is always in a state of pushing out the locking block 72, thereby cooperating with the plug-in unit and the locking unit 6 to lock.

[0031] like Figure 1 , Figure 2 , Fig.13 and Fig.14As shown, an embedding groove 412 is provided inside the action belt 41. The top of the action belt 41 is made of rubber material, and its thickness gradually changes from thick to thin from the middle to the two sides. The embedding groove 412 is used to provide an installation position for the elastic support sheet 42; the elastic support sheet 42 is connected by a third elastic segment 423, two fourth elastic segments 424, two second elastic segments 422 and two first elastic segments 421; the two fourth elastic segments 424 are symmetrically distributed on the concave side of the third elastic segment 423, and the ends of the two fourth elastic segments 424 away from the third elastic segment 423 are fixedly connected to the first sliding bar 425, and the outward turning sides of the two second elastic segments 422 are respectively fixedly connected to the third elastic segment 423. At both ends, the two ends of the second elastic section 422 are fixedly connected with the second slide bar 426 and the fourth slide bar 428 respectively, the concave sides of the two second elastic sections 422 are fixedly connected with the first elastic section 421, and the ends of the two first elastic sections 421 away from the second elastic section 422 are fixedly connected with the third slide bar 427; the inner wall of the embedding groove 412 is provided with a slide groove 413 adapted to the first slide bar 425, the second slide bar 426, the third slide bar 427 and the fourth slide bar 428, and the two ends of the action belt 41 are detachable to expose the embedding groove 412, and the elastic support sheet 42 can directly slide into the interior of the action belt 41 through the slide groove 413, so as to facilitate the replacement of the elastic support sheet 42.

[0032] When a bicycle or a wheelchair needs to pass through the action belt 41, when the wheel presses on the edge of the action 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 to both sides, and the bottom end of the first elastic section 421 is limited and fixed by the third slide bar 427, so the deformation force of the first elastic section 421 will squeeze the top end of the second elastic section 422, squeezing the second elastic section 422 to bend and deform toward the convex side. At the same time, the top of the action belt 41 is in the second elastic section 4 22 is driven by the bending of the action belt 41 to deviate toward the inside of the embedding groove 412, thereby reducing the inclination of the uphill section of the action belt 41, making it more convenient for bicycle or wheelchair users to pass through. After passing through, under the elastic force of the fourth elastic section 424 and the third elastic section 423, the action belt 41 returns to its initial state. When a pedestrian passes through, the force of the foot acts vertically on the top of the action belt 41, and the support of the fourth elastic section 424 and the third elastic section 423 is also strong, which can prevent the action belt 41 from deforming or deforming slightly, and will not affect the pedestrian.

[0033] The present application also provides a warning method of a pedestrian crossing warning device, comprising the following steps: S1. During installation, first dig a pit next to the traffic light pole 1 that matches the support block 3 and the ground box 31, then put the support block 3 and the ground box 31 in and fix them; S2, installing the pedestrian step 22 on the step unit 2 on the ground box 31 through the insertion unit 7 and the locking unit 6, and then locking the insertion unit 7 and the locking unit 6 through the cover unit 8; S3. The pedestrian pedal 22 and the stepping detection structure 5 are used to detect in real time whether there are pedestrians passing or standing. According to the real-time situation of the traffic light 11, the pedestrians are warned through the scrolling screen 12 and the prompt sound 13.

[0034] The working principle of the technical solution provided by the present invention is as follows: when working, the main board inside the traffic light pole 1 determines whether the traffic light 11 is a red light or a green light. When it is a red light, it determines whether there are pedestrians at the sidewalk intersection. When there are no pedestrians, the scrolling screen 12 and the prompt sound 13 are turned off to save power resources. When pedestrians stop, the scrolling screen 12 is turned off and the prompt sound 13 is turned on to remind pedestrians not to run a red light. When the traffic light 11 is a green light, it detects whether there are pedestrians at the sidewalk intersection. When there are no pedestrians, the prompt sound 13 is turned off and the scrolling screen 12 is turned on to remind pedestrians at the opposite intersection. When pedestrians are detected to be stopping, the scrolling screen 12 and the broadcast sound are turned on.

[0035] During installation, a pit is first dug beside the traffic light pole 1 to match the support block 3 and the ground box 31, and then the support block 3 and the ground box 31 are put in and fixed, and the pedal unit 2 is fixed on the support block 3 so that the pedestrian pedal 22 on the pedal unit 2 is stuck in the groove 311 in the box. When the insertion unit 7 is inserted into the locking unit 6, in the initial state, the movable rod 73 moves toward the top of the insertion rod 71 driven by the second connecting rod 732, and the movable rod 73 pulls the first connecting rod 731 driven by the second connecting rod 732, thereby driving the locking card block 72 to rotate along the storage groove 711 toward the inside of the insertion rod 71 through the first connecting rod 731, so that a plurality of locking card blocks 72 are stored in the insertion rod 71, and then the insertion rod 71 is inserted into the three locking balls 6. 2, and then push the first connecting rod 731 by pressing the movable rod 73 to push out the locking block 72, and lock the plug rod 71 through the locking block 72 so that it is restricted under the locking ball 62, and 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 cover unit 8, the plug ring 81 on the cover plate 85 is inserted into the limiting groove 222, and the movable rod 73 is squeezed by pressing the locking rod 83 so that the movable rod 73 is always in the state of pushing out the locking block 72, thereby cooperating with the plug-in unit and the locking unit 6 to lock, and at the same time, the connecting position between the pedestrian pedal 22 and the embedded box 31 is connected by an elastic rubber strip, and finally the adjustment structure 4 is fixed on the deceleration support plate 21.

[0036] When there is a pedestrian on the pedestrian pedal 22 and the pedestrian stands on the pedestrian pedal 22, the pedestrian's own weight will drive the pedestrian pedal 22 to move toward the buffer box 51. At this time, the pedestrian pedal 22 will drive the buffer slider 531 on the connecting slide 532 to slide inside the buffer box 51, so that the hydraulic oil inside the buffer box 51 is introduced into the reflux box 52 through the buffer pipe 55 by the squeezing of the buffer slider 531. The pedestrian pedal 22 is buffered by the slow passage of the hydraulic oil until the entire connecting slide 532 slides into the buffer box 51. At the same time, the reflux slider 521 is displaced toward the elastic power connection component 9 under the squeezing 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 fit each other, so that the detection circuit is closed, and the main board determines whether there is a pedestrian on the pedestrian pedal 22 through the information of circuit closing and disconnection.

[0037] When a pedestrian walks onto the pedestrian pedal 22, there is no external force squeezing the pedestrian pedal 22. The return spring 523 squeezes the reflux slider 521 under the force of its own deformation recovery, and the hydraulic oil inside the reflux box 52 is squeezed through the reflux slider 521, so that the hydraulic oil flows back to the buffer box 51 through the reflux pipe 54. The hydraulic oil flowing back to the buffer box 51 will squeeze the buffer slider 531 to rise, thereby driving the pedestrian pedal 22 to return to its initial position through the pedal pressing unit 53.

[0038] The above description is only a preferred embodiment of the present invention, which is only illustrative and not restrictive of the present invention. Those skilled in the art understand that many changes, modifications, and even equivalences may be made to the present invention within the spirit and scope defined by the claims of the present invention, but all of them will fall within the scope of protection of the present invention.
