Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure. See also Figure 1-10 The embodiment provides a multifunctional dynamic pedestrian crossing signal light, including a lamp pole tube 1 and a column tube 11, the lamp pole tube 1 and the column tube 11 are symmetrically arranged at both ends of the road, and the height of the lamp pole tube 1 and the column tube 11 needs to be the height of the high-speed vehicles to avoid affecting the passing vehicles, a platform 12 is arranged between the lamp pole tube 1 and the column tube 11 through a driving component, and an isolation component is arranged on the lamp pole tube 1 and the column tube 11; it also includes a handrail component, which is arranged on the driving component; it also includes a protective component, which is arranged on the platform 12; when the driving component drives the platform 12 to move downward, the protective component opens to Pedestrians on the platform 12 are protected. The opened protection component can provide shade for pedestrians sitting on the platform 12 so as to provide a more comfortable space. The trigger component drives the isolation components on both sides to move and contact with the handrail component so that pedestrians can walk with support. When the isolation component contacts the handrail component, a route identical to the crosswalk is formed, which is convenient for the blind to move with support and avoids the danger of the blind having a poor sense of direction and easily walking into the traffic lane. The device facilitates the passage of the blind. The device can provide an effective way of crossing the crosswalk for some special groups of people, thereby improving the efficiency and safety of crosswalk passage.

[0022] In an embodiment further provided by the present invention, the driving assembly includes a hydraulic rod 21 fixedly connected to the lamp pole tube 1 and the column tube 11, and the two hydraulic rods 21 are fixedly connected to support blocks 22; the two support blocks 22 are fixedly connected to the same cross beam plate 23, and the platform 12 is connected to the cross beam plate 23 through the horizontal sliding of the hydraulic rod 2. The hydraulic rod 21 and the hydraulic rod 2 are both existing equipment, which are connected to an external power supply to control the movement. When the movement stops, the movement state before the power is cut off is maintained. The hydraulic rod 21 performs vertical movement, and the hydraulic rod 2 performs horizontal movement.

[0023] Furthermore, the isolation component includes a seat frame 31 fixedly connected to the lamp pole tube 1 and the column tube 11, and an isolation plate 32 is slidably connected to the seat frame 31; a spring 33 is arranged between the isolation plate 32 and the seat frame 31, and the elastic force of the spring 33 drives the isolation plate 32 to approach the seat frame 31, and a handrail 1 34 and a handrail 2 35 are fixedly connected to the isolation plate 32. A fence needs to be set on the seat frame 31. The setting of the seat frame 31 is convenient for pedestrians to rest while waiting. Night signs can be set on the seat frame 31 as needed to improve safety when walking.

[0024] Furthermore, the trigger assembly includes a wedge-shaped rod 41 fixedly connected to the cross beam plate 23, and a wedge-shaped through groove 42 is opened on the isolation plate 32. The wedge-shaped through groove 42 is engaged with the wedge-shaped through groove 42 during the movement of the wedge-shaped rod 41. When the platform 12 moves downward, the wedge-shaped rod 41 moves synchronously and first contacts with the wedge-shaped through groove 42 on the isolation plate 32, triggering the isolation plate 32 to drive the support rod 1 34 and the support rod 2 35 to move to separate the space for the platform 12 to descend, thereby improving the safety of the platform 12 when it moves downward.

[0025] In an embodiment further provided by the present invention, the handrail assembly includes an L-shaped fixing block 51 fixedly connected to the crossbeam plate 23, and a handrail three 52 and a handrail four 53 are fixedly connected to the L-shaped fixing block 51; sleeve units are provided at both ends of the handrail three 52 and the handrail four 53.

[0026] Specifically, the sleeve unit includes an armrest 61 elastically and slidably connected to armrest three 52 and armrest four 53, and a connecting strip 62 is fixedly connected between the two armrests 61 on the same side. The connection parts between the armrests 3 52 and armrest four 53 and the armrest 61 need to be set to be elastic, and the connecting strip 62 is pulled to move so that the armrests 61 on armrest three 52 and armrest four 53 can move synchronously, which is convenient for separating a certain space between armrest one 34 and armrest two 35, so that people can enter the movement space of the platform 12 for use. One end of armrest one 34 is set on the same straight line with armrest three 52 to provide guidance for walking blind people, and one end of armrest two 35 is set on the same straight line with armrest four 53 to support pedestrians sitting on the platform 12.

[0027] In the embodiment provided by the present invention, the protective assembly includes an L-shaped protective plate 71 vertically slidably connected to the carrier 12, and a spring 72 is arranged between the L-shaped protective plate 71 and the carrier 12; both sides of the L-shaped protective plate 71 are rotatably connected with damping rotating rods 73, and side plates 74 are arranged on the two damping rotating rods 73. A driving unit for driving the damping rotating rods 73 to rotate is arranged on the carrier 12, and the side plates 74 are symmetrically arranged on both sides of the L-shaped protective plate 71, and the bottom of the L-shaped protective plate 71 is arranged to be inclined to prevent rainwater and snow water from rolling off the L-shaped protective plate 71. For some heavy rain and snow weather or windy weather, it is not recommended to use the carrier 12, but the isolation assembly and the handrail assembly can be used to hold on to cross the road.

[0028] Specifically, the driving unit includes a gear 81 fixedly connected to the damping rotating rod 73, a slide groove 82 is opened on the platform 12, and a rack plate 83 is fixedly connected in the slide groove 82. When the L-shaped protective plate 71 moves upward relative to the platform 12, the gear 81 engages with the rack plate 83 in the middle. Through the engagement of the gear 81 with the rack plate 83 in the slide groove 82, the side panels 74 on both sides of the L-shaped protective plate 71 can be unfolded, thereby expanding the protection area for pedestrians on the platform 12. When the L-shaped protective plate 71 moves downward relative to the platform 12, the gear 81 engages with the rack plate 83 in the reverse direction again, so that the unfolded side panels 74 retract and form a closed space with the L-shaped protective plate 71, which can isolate the use of birds and prevent birds from polluting the platform 12.

[0029] In the solution further provided by the present invention, a limit rod 91 and a control panel 92 are fixedly connected to the lamp pole tube 1 and the column tube 11. A dynamic signal light group 93 is also provided on the lamp pole tube 1. The limit rod 91 is arranged above the L-shaped protective plate 71. When the platform 12 moves upward under the action of the driving component, the L-shaped protective plate 71 arranged thereon will be squeezed by the limit rod 91, so that the platform 12 moves upward and the L-shaped protective plate 71 stops moving. At this time, the side panel 74 retracts and forms a closed space with the L-shaped protective plate 71. The control panel 92 is mainly provided to radiate a signal to the driving component that controls the movement of the platform 12. When the control panel 92 is pressed, if the dynamic signal light group 93 is green, the driving component controls the platform 12 to descend. If the dynamic signal light group 93 is red, the driving component receives the signal and waits for the dynamic signal light group 93 to turn green before working.

[0030] In the solution further provided by the present invention, an auxiliary component is also provided on the platform 12, and the auxiliary component includes a mounting frame 101 slidably connected to the bottom of the platform 12; a spring three 102 is provided between the mounting frame 101 and the platform 12, and an auxiliary wheel 103 is also provided on the mounting frame 101, and handrails 104 are also provided on both sides of the platform 12. By providing the auxiliary component, the stability of the platform 12 when moving on the ground can be improved, and by providing the handrail 104 on the platform 12, the safety of sitting on the platform 12 can be improved, and a controller for driving the hydraulic rod two to move needs to be provided on the handrail 104.

[0031] Working principle: When a person with limited mobility needs to cross the road, he presses the control panel 92 on the lamp pole tube 1 or the column tube 11. If the dynamic signal light group 93 shows a green light, the drive component controls the platform 12 to descend. When the platform 12 descends, the L-shaped protective plate 71 arranged thereon will slowly move upward under the action of the spring 2 72. The upward movement of the L-shaped protective plate 71 drives the side rod and the damping rotating rod 73 to move synchronously. At this time, the gear 81 on the damping rotating rod 73 will contact the rack plate 83 in the slide groove 82, triggering the damping rotating rod 73 to drive the side plate 74 to rotate and open, and as the platform 12 gradually moves downward, the wedge-shaped rod 41 arranged on the crossbeam plate 23 will contact the wedge-shaped through groove 42 on the isolation plate 32, and gradually enter the interior of the wedge-shaped through groove 42, thereby triggering the isolation plate 32 to move out of the seat frame 31. Until the wedge-shaped rod 41 is fully inserted into the wedge-shaped through groove 42 of the isolation plate 32, the isolation plate 32 is The plate 32 drives the handrail 1 34 and the handrail 2 35 to move to the bottom of the handrail 3 52 and the handrail 4 53 until the platform 12 is completely lowered under the action of the hydraulic rod 1 21. At this time, the connecting strip 62 is pulled to make the handrail 61 elastically sliding on the handrail 3 52 and the handrail 4 53 move, and after a certain space is separated from the handrail 1 34 and the handrail 2 35, the pedestrian enters and releases the pulling force on the connecting strip 62, so that the elastic member arranged between the handrail 61 and the handrail 3 52 and the handrail 4 53 is reset, so that one end of the handrail 61 contacts with the handrail 1 34 and the handrail 2 35. At this time, the pedestrian sits on the platform 12, and turns the handrail 104 and operates the controller on the handrail 104, so that the hydraulic rod 2 works to push the platform 12 to drive the pedestrian to move on the road, and the blind person can hold the handrail 1 34 and walk to the other side of the road along the handrail 1 34, the handrail 61 and the handrail 3 52; When the pedestrian leaves the platform 12 and the dynamic signal light group 93 is still green, the platform 12 can remain on the ground. When the platform 12 does not transport the pedestrian to the opposite side, the time it takes for the dynamic signal light group 93 to turn red increases until the pedestrian leaves the rear platform 12. After the platform 12 moves up and resets, the dynamic signal light group 93 turns red and stops passing. When the platform 12 moves up, the wedge rod 41 moves out of the wedge-shaped through groove 42 on the isolation plate 32, and the isolation plate 32 will reset under the action of the spring 1 33. After the platform 12 moves up, the limit rod 91 will limit the L-shaped protective plate 71. At this time, the platform 12 continues to move up, and the L-shaped protective plate 71 stops moving. At this time, the damping rotating rod 73 on the L-shaped protective plate 71 will rotate in the opposite direction and contract under the action of the rack plate 83, forming a sealed space with the L-shaped protective plate 71 to protect the platform 12.
