Description
Technical Field
[0001] This utility model belongs to the field of rail transit technology, and specifically relates to an LED guidance device for passenger flow control in rail transit. Background Technology
[0002] Currently, Chinese utility model patent CN206986783U discloses a computer-based urban rail transit passenger flow environment monitoring system. The system has the following defects during use: relying solely on light warnings during restricted hours can easily lead to passengers accidentally entering restricted areas; direct collisions with rigid railings can cause injuries and equipment damage, making it difficult to improve traffic efficiency; at the same time, rigid structures are prone to permanent deformation or breakage when compressed, leading to frequent maintenance and replacement; and the inability to automatically correct deviations can cause railing misalignment, which not only affects aesthetics but may also create new traffic obstacles and pose a risk of abrasions to passengers.
[0003] To address the problems mentioned above, an LED guidance device for pedestrian flow control in rail transit is proposed. Utility Model Content
[0004] The purpose of this utility model is to provide an LED guidance device for passenger flow control in rail transit, which has the advantages of dual protection for personnel and device and dispersion of impact force.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: An LED guiding device for passenger flow control in rail transit includes a main unit. Rotary shafts are rotatably connected to the front and rear top bottom sides of the inner wall of the main unit. A railing is fixedly sleeved on the surface of the rotating shaft. A sliding groove is provided on the front and back sides of the railing near the rotating shaft and at the end away from the rotating shaft. A slider is slidably connected to the end of the inner wall of the sliding groove on one side, and a slider is slidably connected to the end of the inner wall of the sliding groove on one side, near the inner wall of the sliding groove on one side. An elastic plate is bolted to the outside of the slider on one side, and an elastic plate is bolted to the outside of the slider on one side. The end of a spring away from the elastic plate is bolted to the position between the two sliding grooves on one side. A protective mechanism is provided at the bottom of the main unit.
[0006] The above technical solution is as follows: When the LED no-entry light is lit, it can prevent people from entering the area of the guide device barrier. The guide device is equipped with a foldable barrier, which has two elastic plates, namely, elastic plate one and elastic plate two, to prevent people from colliding. When people collide, elastic plate one retracts, and slider one moves outward. A sliding groove limits the movement of slider one. After elastic plate one absorbs a certain amount of collision and compression force, elastic plate one and elastic plate two come into contact. Elastic plate two retracts, and slider two moves outward. A sliding groove limits the movement of slider two, and elastic plate two continues to absorb a certain amount of collision and compression force. When elastic plate two retracts, the spring retracts accordingly to protect the barrier. When people come into contact with the elastic plates, the outer protective pad prevents people from being scratched, and the inner protective pad prevents injury when elastic plate one and elastic plate two come into contact. When personnel stop contacting the protective barrier after a collision, the elastic plates 1 and 2, along with the spring, return to their original positions. When the LED traffic light illuminates, the cylinder contracts, moving the rack and pinion. This movement drives the half-gear to rotate, which in turn rotates the barrier. The rotating shaft limits the barrier's rotation, causing it to fold upwards, indicating that passage is permitted. If passage is prohibited, the cylinder contracts, unfolding the barrier downwards. When the LED no-entry light illuminates, the folded barrier, in conjunction with the elastic protective plate, forms a physical barrier, preventing people from accidentally entering the area and reducing collision damage through its buffer design. When the LED traffic light illuminates, the barrier quickly retracts, ensuring efficient pedestrian flow. This optimizes the passenger experience while ensuring passenger safety, making it particularly suitable for managing high-traffic scenarios such as subway peak hours.
[0007] The present invention is further configured such that the protective mechanism includes a rotating block, the rotating block is bolted to the bottom of the main unit, the rotating block is bolted to both sides of the rotating block, the bottom of the rotating block is rotatably connected to a base, the front and rear ends of both sides of the base are bolted to protrusions, a roll box is embedded in one side of the two protrusions facing each other, a coil spring is bolted to the top and bottom center of the roll box, and the end of the coil spring away from the roll box is bolted to the front and back of the connecting rod, and a folding mechanism is provided at one end of the two horizontal railings facing each other.
[0008] The above technical solution employs a protective device. When a large flow of people moves and the barrier is pushed down, the barrier rotates due to the pressure. This rotation causes the rotating block to rotate, which in turn causes the connecting rod to rotate. The rotating rod then stretches the coil spring at the end of the roll box away from the connecting rod. When the pressure from the pull rod disappears, the stretched coil spring contracts, causing the mechanism to return to its original position. This improves the durability and safety of the device. When a large flow of people pushes against the barrier, the allowable elastic shift in angle can effectively disperse the impact force and prevent structural deformation. The built-in coil spring ensures automatic reset after the pressure is released, preventing metal fatigue fracture caused by continuous stress.
[0009] The present invention is further configured such that the folding mechanism includes a half gear, the half gear is welded at one end of two horizontal railings opposite each other, the side of the half gear away from the railings is engaged with a rack, the bottom of the main unit is provided with a slot, the bottom of the slot is embedded with a cylinder, and the top of the cylinder is bolted to the bottom of the rack, and a spring is bolted to the inner side of the second elastic plate.
[0010] The above technical solution employs a folding mechanism. The cylinder retracts, causing the rack to move. The rack moves, causing the half-gear to rotate. The half-gear rotates, causing the railing to rotate. The rotating shaft limits the rotation of the railing. The railing folds upward to indicate that pedestrians can pass. When passage is blocked, the cylinder retracts, causing the railing to unfold downward.
[0011] The present invention is further configured such that an LED access light is provided on the left side of the bottom of the front of the host, an LED stop light is provided on the right side of the bottom of the front of the host, and an LED screen is provided on the top of the front of the host.
[0012] The above technical solution employs LED access lights and LED no-entry lights to indicate whether pedestrian traffic is permitted, and LED screens to display information.
[0013] The present invention is further configured such that a slider three is bolted to the back of the rack, and a groove three is provided at the center of the rear end of the main unit, and the surface of the groove three is slidably connected to the interior of the slider three.
[0014] The above technical solution is adopted: by setting slider three and slide groove three, the movement of the rack can be limited.
[0015] The present invention is further configured such that a limiting block is bolted to one end of the connecting rod away from the rotating block, and a limiting groove is formed in the middle of the two sides inside the base, and the inside of the limiting groove is slidably connected to the surface of the limiting block.
[0016] The above technical solution, by setting a limit block and a limit groove, can limit the rotation of the connecting rod.
[0017] The present invention is further configured such that a damper is sleeved inside the spring.
[0018] The above technical solution involves setting a damper to limit the movement of the spring.
[0019] The present invention is further provided that protective pads are adhered to the front and back of the elastic plate.
[0020] The above technical solution is adopted: by setting up protective pads, when people come into contact with the elastic plate, the outer protective pads prevent people from being scratched, and the inner protective pads prevent damage when elastic plate one and elastic plate two come into contact.
[0021] In summary, this utility model has the following beneficial effects:
[0022] 1. This utility model uses a folding barrier combined with an elastic protective plate to form a physical barrier when the LED no-entry light is lit. This not only prevents people from accidentally entering the area, but also reduces collision damage through the buffer design. When the LED traffic light is lit, the barrier quickly retracts to ensure efficient passage of people. It optimizes the passage experience while ensuring passenger safety, and is especially suitable for order management in high-passenger-flow scenarios such as subway morning and evening rush hours.
[0023] 2. This utility model improves the durability and safety of the device. When a large flow of people squeezes the railing, the allowable elastic displacement of the angle can effectively disperse the impact force and avoid rigid deformation of the structure. The built-in coil spring ensures automatic reset after the pressure is released, preventing metal fatigue fracture caused by continuous force. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.
[0031] Example 1: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4An LED guide device for pedestrian flow control in rail transit includes a main unit 1. Rotary shafts 2 are rotatably connected to the front and rear ends of the main unit 1. A railing 3 is fixedly sleeved on the surface of the rotating shaft 2. A groove 4 is formed on the front and back of the railing 3 on the side closest to the rotating shaft 2 and the side furthest from the rotating shaft 2. A slider 5 is slidably connected to the end furthest from the inner wall of one groove 4, and a slider 6 is slidably connected to the end closest to the inner wall of one groove 4. A spring is bolted to the outside of one slider 5. A spring 21, located on the outer side of a slider 26, is bolted to a spring plate 10. The end of the spring 21 furthest from the spring plate 20 is bolted to a position between two sliding grooves 4 on one side. A protective mechanism is installed at the bottom of the main unit 1. When the LED prohibition light 23 is lit, it can prevent people from entering the area on the guide device barrier. The guide device is equipped with a foldable railing 3, which contains the spring plate 19 and the spring plate 20 to prevent collisions. When people collide, the spring plate 19 retracts, and the slider 15 moves outwards. The groove 4 limits the movement of slider 5. After elastic plate 9 absorbs a certain amount of collision and compression force, elastic plate 9 and elastic plate 10 come into contact. Elastic plate 10 contracts, and slider 6 moves outward. The groove 4 limits the movement of slider 6. Elastic plate 10 continues to absorb a certain amount of collision and compression force. When elastic plate 10 contracts, spring 21 contracts accordingly, protecting the railing 3. When people come into contact with the elastic plate, the outer protective pad 27 prevents people from being scratched, and the inner protective pad 27 prevents the elastic plate from being injured. When plate 9 and elastic plate 10 come into contact, they are damaged. When the person who collided with and squeezed the protective plate 1 stops contacting it, elastic plate 9, elastic plate 10 and spring 21 rebound and return to their original state. When the LED passage light 22 lights up, cylinder 20 retracts and drives rack 18 to move. The movement of rack 18 drives half gear 17 to rotate. The rotation of half gear 17 drives railing 3 to rotate. The rotating shaft 2 limits the rotation of railing 3. Railing 3 folds up and retracts to indicate that the flow of people can pass. When it is not possible to pass, cylinder 20 retracts and drives railing 3 to unfold downward.
[0032] refer to Figure 1 , Figure 2 , Figure 3 The folding mechanism includes a half gear 17, which is welded to one end of two horizontal railings 3 facing each other. A rack 18 meshes with the side of the half gear 17 away from the railings 3. A slot 19 is provided at the bottom inside the main unit 1. A cylinder 20 is embedded in the bottom of the slot 19, and the top of the cylinder 20 is bolted to the bottom of the rack 18. A spring 21 is bolted to the inner side of the elastic plate 2 10. By setting up the folding mechanism, the cylinder 20 retracts and drives the rack 18 to move. The movement of the rack 18 drives the half gear 17 to rotate. The rotation of the half gear 17 drives the railings 3 to rotate. The rotating shaft 2 limits the rotation of the railings 3. When the railings 3 are folded up, they indicate that the flow of people can pass. When the flow of people cannot pass, the cylinder 20 retracts and drives the railings 3 to unfold downwards.

By setting the LED access light 22 and the LED no-entry light 23, it is possible to indicate whether the flow of people can pass. By setting the LED screen 24, it is possible to display prompt information.

A groove 3 8 is provided in the center of the rear end of the main unit 1, and the surface of the groove 3 8 is slidably connected to the inside of the slider 3 7. By setting the slider 3 7 and the groove 3 8, the movement of the rack 18 can be limited.
[0035] refer to Figure 3 , Figure 4 A damper 28 is sleeved inside the spring 21. By setting the damper 28, the spring 21 can be limited.
[0036] refer to Figure 1 , Figure 3 , Figure 4 Protective pads 27 are adhered to the front and back of the elastic plate 9. By setting the protective pads 27, when people come into contact with the elastic plate, the outer protective pad 27 prevents the people from being scratched, and the inner protective pad 27 prevents the elastic plate 9 from being damaged when it comes into contact with the elastic plate 10.
[0037] Brief description of usage: When the LED no-entry light 23 is lit, it can prevent people from entering the area blocked by the guide device. The guide device is equipped with a foldable barrier 3, which has two elastic plates, 9 and 10, to prevent collisions. When people collide, the elastic plate 9 retracts, the slider 5 moves outward, and the slide rail 4 limits the movement of the slider 5. After the elastic plate 9 absorbs a certain amount of collision and compression force, it comes into contact with the elastic plate 10, which retracts, and the slider 6 moves outward. The slide rail 4 limits the movement of the slider 6. The elastic plate 10 continues to absorb a certain amount of collision and compression force. When the elastic plate 10 retracts, the spring 21 retracts as well, and the damper 28 limits the spring 21. The barrier 3 provides protection. When people come into contact with the elastic plate, the outer protective pad 27 prevents people from getting scratched, and the inner protective pad 27 prevents damage when the elastic plate 1 9 and elastic plate 2 10 come into contact. When people stop contacting the protective plate 1 after colliding and squeezing it, the elastic plate 1 9, elastic plate 2 10 and spring 21 rebound and return to their original positions. When the LED passage light 22 is lit, the cylinder 20 retracts and drives the rack 18 to move. The slider 3 7 and the slide groove 3 8 limit the movement of the rack 18. The movement of the rack 18 drives the half gear 17 to rotate. The rotation of the half gear 17 drives the barrier 3 to rotate. The rotating shaft 2 limits the rotation of the barrier 3. The barrier 3 folds upward and retracts to indicate that people can pass. When passage is not possible, the cylinder 20 retracts and drives the barrier 3 to unfold downward.
[0038] Example 2: Reference Figure 1 , Figure 2 , Figure 5 An LED guiding device for passenger flow control in rail transit includes a protective mechanism comprising a rotating block 11, which is bolted to the bottom of a main unit 1. Connecting rods 12 are bolted to both sides of the rotating block 11. A base 13 is rotatably connected to the bottom of the rotating block 11. Protrusions 14 are bolted to the front and rear ends of both sides inside the base 13. A roll box 15 is embedded in the side of the two protrusions 14 facing each other on one side. A coil spring 16 is bolted to the top and bottom center inside the roll box 15. The end of the coil spring 16 away from the roll box 15 is bolted to the front and back of the connecting rod 12. A folding mechanism is provided at the opposite end of two horizontal railings 3. When a large passenger flow moves and the device of the railing 3 is squeezed down, the railing 3 rotates due to the squeeze. The rotation of the railing 3 drives the rotating block 11 to rotate, which in turn drives the connecting rod 12 to rotate. The rotation of the connecting rod 12 stretches the coil spring 16 away from the roll box 15. When the squeezing force of the lever disappears, the stretched coil spring 16 retracts, driving the mechanism to return to its original position, thus improving the durability and safety of the device.
[0039] refer to Figure 5The end of the connecting rod 12 away from the rotating block 11 is bolted with a limiting block 25. A limiting groove 26 is opened in the middle of both sides inside the base 13, and the inside of the limiting groove 26 is slidably connected to the surface of the limiting block 25. By setting the limiting block 25 and the limiting groove 26, the rotation of the connecting rod 12 can be limited.
[0040] Brief description of the usage process: When a large flow of people moves, the device that presses down the barrier 3 will cause the barrier 3 to rotate due to the pressure. The rotation of the barrier 3 will drive the rotating block 11 to rotate, which in turn drives the connecting rod 12 to rotate. The limiting block 25 and the limiting groove 26 limit the rotation of the connecting rod 12. The rotation of the connecting rod 12 will cause the coil spring 16, which is away from the end of the roll box 15, to stretch. When the pressure of the pull rod disappears, the stretched coil spring 16 will contract, driving the mechanism to return to its original position, thus improving the durability and safety of the device.
