Description

Technical Field

[0001] This application relates to the technical field of traffic safety, and in particular to an automatic alarm and reminder device for pedestrians being stepped on. Background Technology

[0002] Currently, curb ramps are usually installed at the intersection of pedestrian and motor vehicle lanes on urban roads to smoothly transition the height difference between the pedestrian and vehicle lanes. The bottom part of the curb ramp where it meets the vehicle lane is made of flat stone. At the same time, traffic lights are installed at the curb ramps to control the right of way for pedestrians and motor vehicles.

[0003] Currently, most pedestrian crossings rely solely on traffic light changes, color-coded road markings, and a few warning signs to guide pedestrians across the road during green lights and to wait in the pedestrian area within the curb ramp during red lights. Some busy sections may be equipped with traffic assistants to assist in management, but overall, pedestrians still rely on their own traffic safety awareness and adherence to traffic rules.

[0004] Regarding the aforementioned technologies, due to the lack of an immediate intervention mechanism for pedestrian violations, pedestrians often step onto the flat stones at the intersection of the curb and the roadway during red lights, due to their eagerness to cross, disregard for traffic signals, or unclear understanding of boundary areas. At this point, pedestrians are already within the potential danger zone of vehicles turning or starting. Existing warning methods relying solely on traffic lights and signs are insufficient to promptly remind and stop such violations. This not only easily triggers emergency swerves by drivers, increasing the risk of traffic accidents, but also fails to effectively regulate pedestrian behavior, resulting in loopholes in traffic order management and an inability to fully guarantee pedestrian safety while crossing the road. Utility Model Content

[0005] In order to provide timely reminders to pedestrians who violate traffic rules during red light periods and reduce the risk of traffic accidents, this application provides an automatic alarm reminder device for pedestrian crossings.

[0006] This application provides an automatic alarm and reminder device for pedestrian walkways, which adopts the following technical solution: An automatic pedestrian step alarm device includes a stainless steel frame, a step pedal, an elastic connector, a pressure sensor, and an alarm device. The step pedal is fixedly connected to the stainless steel frame via the elastic connector. The pressure sensor is fixedly disposed inside the stainless steel frame. When the step pedal is not under pressure, it is located at the top of the stainless steel frame, and the step pedal is not in contact with the receiving contact of the pressure sensor. When the step pedal is under pressure, it moves downward and abuts against the receiving contact of the pressure sensor. The pressure sensor is signal-connected to the alarm device.

[0007] By adopting the above technical solution, the pressure sensor can be triggered by the downward movement of the pedal, and then the pressure sensor can be linked to the alarm device to activate the warning, so as to realize the automatic alarm when pedestrians step on the pedal in violation of regulations, timely remind pedestrians to pass in a standardized manner, and reduce the risk of traffic accidents.

[0008] Preferably, the stainless steel outer frame has a concrete layer inside, and the top of the concrete layer is lower than the foot pedal.

[0009] By adopting the above technical solution, the concrete layer can provide stable support for the internal structure of the stainless steel frame. At the same time, the design of its top being lower than the pedal provides sufficient space for the pedal to move downward under force, avoiding the inability to trigger the pressure sensor due to insufficient space when the pedal moves downward, thus ensuring the normal operation of the device.

[0010] Preferably, the concrete layer has first through holes at both ends, the elastic connector is located inside the first through holes, one end of the elastic connector is fixedly connected to the bottom of the pedal, and the other end of the elastic connector is fixedly connected to the inner wall of the stainless steel frame away from the pedal.

[0011] By adopting the above technical solution, the first through hole can limit the elastic connector, preventing the elastic connector from shifting laterally during the extension and retraction process. At the same time, fixing both ends of the elastic connector to the pedal and the inner wall of the stainless steel outer frame respectively can ensure that the elastic connector can stably realize the reset function of the pedal and improve the structural stability of the device.

[0012] Preferably, it further includes a first limiting rod and a second limiting rod, the first limiting rod being fixedly connected to the bottom of the pedal, and the second limiting rod being fixedly connected to the inner wall of the stainless steel outer frame on the side away from the pedal; one end of the elastic connector is sleeved on the first limiting rod, and the other end of the elastic connector is sleeved on the second limiting rod.

[0013] By adopting the above technical solution, the first limit rod and the second limit rod can further restrict the extension and retraction direction of the elastic connector, avoid the elastic connector from tilting or twisting due to uneven force, ensure that the elastic connector always extends and retracts stably in the vertical direction, and ensure that the pedal can rise and fall smoothly to accurately trigger the pressure sensor.

[0014] Preferably, the concrete layer has at least one second through hole distributed along the length of the foot pedal, the pressure sensor is installed in the second through hole, and the receiving contact of the pressure sensor protrudes from the top surface of the concrete layer.

[0015] By adopting the above technical solution, the second through hole provides a stable installation position for the pressure sensor, and the design of the pressure sensor receiving contact protruding from the top surface of the concrete layer ensures that the pedal moves down under force and accurately contacts the receiving contact, avoiding the failure of the pedal to trigger the pressure sensor due to the contact position being too low, thus ensuring the reliability of alarm triggering.

[0016] Preferably, the bottom of the foot pedal is provided with a limiting block, and the top of the concrete layer is provided with a limiting groove corresponding to the position of the limiting block, and the limiting block and the limiting groove are inserted into each other.

[0017] By adopting the above technical solution, the insertion and engagement of the limiting block and the limiting groove can limit the horizontal displacement of the pedal, prevent the pedal from shifting or tilting laterally during the force application or reset process, ensure that the pedal always moves in the vertical direction, and ensure that it can accurately contact the pressure sensor receiving contact, thereby improving the operational stability of the device.

[0018] Preferably, the alarm device includes a controller and a buzzer, the buzzer being fixedly installed on a bollard at the curb of the sidewalk, and the controller being connected to the pressure sensor and the buzzer signal respectively.

[0019] By adopting the above technical solution and installing the buzzer on the bollard, the warning sound can be spread over a wider range, making it easier for pedestrians to hear the warning sound clearly. The controller realizes the signal linkage between the pressure sensor and the buzzer, which can immediately activate the buzzer to issue a warning after a pedestrian steps on and triggers the pressure sensor, quickly reminding the pedestrian to stop the violation.

[0020] Preferably, the alarm device includes a controller and an LED light strip, the LED light strip being installed around the side of the bollard at the pedestrian curb ramp, and the controller being connected to the pressure sensor and the LED light strip respectively.

[0021] By adopting the above technical solution, the LED light strip is installed on the side of the bollard, and its illuminated light can directly warn pedestrians who violate the rules. The warning effect is more prominent, especially in low-light environments. The controller links the pressure sensor and the LED light strip, so that the light can be turned on immediately after being stepped on, further enhancing the reminder effect on pedestrians who violate the rules.

[0022] In summary, this application includes at least one of the following beneficial technical effects: It can automatically alarm when pedestrians illegally step on the flat stone area where the curb ramp and the roadway intersect during red light. It can intervene in pedestrian violations in a timely manner through dual sound and light warnings to reduce the risk of traffic accidents. The rational design of the structure of each component of the device, such as the setting of concrete layer, limit rod, limit block, etc., improves the overall structural stability and operational reliability of the device, and ensures that the alarm function is accurate and triggered in a timely manner. The alarm device is installed in a location that balances warning effectiveness with space efficiency. The combination of the buzzer and LED light strip can adapt to different lighting and environmental conditions, effectively reminding pedestrians who violate traffic rules and helping to regulate traffic order.

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail.

[0026] This application discloses an automatic alarm and reminder device for pedestrian walkways.

[0027] Reference Figure 1 and Figure 2 An automatic alarm device for pedestrian walkways includes a stainless steel frame 1, a foot pedal 2, an elastic connector 3, a pressure sensor 4, and an alarm device. The foot pedal 2 is fixedly connected to the stainless steel frame 1 via the elastic connector 3. The pressure sensor 4 is fixedly installed inside the stainless steel frame 1. When the foot pedal 2 is not under pressure, it is located at the top of the stainless steel frame 1, and the bottom of the foot pedal 2 is not in contact with the receiving contact 41 of the pressure sensor 4. When the foot pedal 2 is under pressure, it moves downward and abuts against the receiving contact 41 of the pressure sensor 4. The pressure sensor 4 is signal-connected to the alarm device to realize immediate linkage alarm upon receiving a pressure signal.

[0028] At the intersection of the pedestrian curb ramp and the roadway, multiple foot pedals 2 are installed on the flat stone section. When a pedestrian attempts to cross the road against a red light, the pedestrian will enter the coverage area of ​​the foot pedals 2. When the pedestrian steps on a foot pedal 2 while crossing against a red light, the foot pedal 2 overcomes the elastic force of the elastic connector 3 and moves downward until the bottom of the foot pedal 2 abuts against the pressure sensor 4. The pressure sensor 4 receives the pressure signal and transmits a control command to the alarm device through the controller, driving the alarm device to activate the warning function, thereby providing an immediate reminder of the pedestrian's violation.

[0029] Reference Figure 2 and Figure 3 In this embodiment, the stainless steel outer frame 1 includes a base plate 11 and a side plate 12. The side plate 12 is vertically arranged along the outer periphery of the base plate 11, and the base plate 11 and the side plate 12 are fixedly connected by welding. The base plate 11 and the side plate 12 together form a frame structure with a top opening. The foot pedal 2 is located at the top opening of the stainless steel outer frame 1. The bottom of the foot pedal 2 is fixedly connected to the base plate 11 of the stainless steel outer frame 1 by an elastic connector 3. When the foot pedal 2 is not subjected to external force, the foot pedal 2 is flush with the top surface of the side plate 12 of the stainless steel outer frame 1.

[0030] The interior of the stainless steel outer frame 1 is filled with a concrete layer 5. The top of the concrete layer 5 is slightly lower than the top surface of the side plate 12. The top of the concrete layer 5 forms a limiting support surface for the downward movement of the foot pedal 2. The lowest position of the foot pedal 2 is when it abuts against the top of the concrete layer 5 to avoid excessive downward movement that could cause damage to the components.

[0031] In this embodiment, the concrete layer 5 has two first through holes 51, which are symmetrically distributed at both ends of the concrete layer 5. The elastic connector 3 is installed inside the first through holes 51. One end of the elastic connector 3 is fixedly connected to the bottom of the foot pedal 2, and the other end of the elastic connector 3 is fixedly connected to the base plate 11 of the stainless steel outer frame 1. In this embodiment, the elastic connector 3 is a spring.

[0032] When the pedal 2 is not subjected to external force, it is flush with the top surface of the side plate 12 of the stainless steel frame 1 by its own weight and the elastic force of the elastic connector 3. When the pedal 2 is subjected to external force, the elastic connector 3 deforms and the pedal 2 moves downward within the stainless steel frame 1. When the bottom of the pedal 2 comes into contact with the pressure sensor 4, the pressure sensor 4 receives a pressure signal. After the external force acting on the pedal 2 disappears, the pedal 2 automatically returns to the state of being flush with the top surface of the side plate 12 by the elastic reset of the elastic connector 3.

[0033] In this embodiment, each elastic connector 3 is internally fitted with a first limiting rod 6 and a second limiting rod 7. The first limiting rod 6 is located at the top of the elastic connector 3, and its top end is fixed to the bottom of the foot pedal 2. The second limiting rod 7 is located at the bottom of the elastic connector 3, and its bottom end is fixed to the base plate 11 of the stainless steel outer frame 1. The first and second telescopic rods limit the radial displacement of the elastic connector 3 during extension and retraction, ensuring that the elastic connector 3 always extends and retracts stably along the axial direction.

[0034] The concrete layer 5 is also provided with a second through hole 52, and the pressure sensor 4 is installed in the second through hole 52. In this embodiment, five second through holes 52 are evenly arranged along the length of the foot pedal 2 in the concrete layer 5, and the receiving contact 41 of the pressure sensor 4 is higher than the top surface of the concrete layer 5. When the foot pedal 2 is flush with the top surface of the side plate 12, the bottom of the foot pedal 2 and the receiving contact 41 of the pressure sensor 4 do not contact each other; when the foot pedal 2 is subjected to external force and descends, the bottom of the foot pedal 2 and the receiving contact 41 abut against each other, and the pressure sensor 4 receives the pressure signal and transmits the control command to the alarm device to drive the alarm device to activate the warning function, thereby realizing the immediate reminder of pedestrian violations.

[0035] Furthermore, four limiting blocks 21 are provided at the bottom of the pedal 2, and four limiting grooves 53 are provided at the top of the concrete layer 5. The limiting blocks 21 and the limiting grooves 53 are interlocked. This structure can not only limit the horizontal displacement of the pedal 2, but also ensure that the pedal 2 moves smoothly in the vertical direction when it moves down, avoiding tilting or deviation.

[0036] Reference Figure 1 and Figure 4 The alarm device includes a buzzer 8, an LED light strip 9, and a controller connected to the traffic lights. The buzzer 8 is fixedly installed on the bollard of the pedestrian curb ramp, and the LED light strip 9 is arranged around the side of the bollard. The pressure sensor 4 establishes a synchronous connection with the buzzer 8 and the LED light strip 9 through the controller, so that signal linkage can be achieved without wiring.

[0037] During a red light, the controller detects the red light signal. When a pedestrian steps on pedal 2, pedal 2 is subjected to external force and moves downwards. The bottom of pedal 2 comes into contact with the receiving contact 41 of pressure sensor 4. Pressure sensor 4 receives the pressure signal and instantly sends an alarm signal to the controller. After receiving the alarm signal, the controller sends a trigger signal to the control terminals of buzzer 8 and LED light strip 9 via the wireless transmission module. Buzzer 8 immediately emits a warning sound, and LED light strip 9 simultaneously lights up, informing the pedestrian that the light is currently red and passage is prohibited through a dual audio-visual reminder. When the pedestrian leaves pedal 2 during the red light period and the pressure disappears, pressure sensor 4 stops outputting signals, and buzzer 8 and LED light strip 9 automatically stop working and return to standby mode. When the traffic light changes to green, the controller detects the green light signal and stops sending trigger signals to the control terminals of buzzer 8 and LED light strip 9.

[0038] The implementation principle of this application embodiment is as follows: a stable installation foundation is constructed by the stainless steel outer frame 1 and the concrete layer 5. The elastic connector 3, in conjunction with the limiting rod and the limiting block 21, enables the stable vertical lifting and automatic reset of the pedal 2. During the red light period, the pedestrian stepping on the pedal triggers the pressure sensor 4, which activates the sound and light warning through the wireless signal linkage of the buzzer 8 and the LED light strip 9. With the help of the parallel layout and synchronous response of multiple devices, the pedestrian area is instantly reminded and fully covered for illegal passage.

[0039] 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.
