Abstract
Description
Technical Field
[0001] This application relates to the field of auxiliary equipment technology for buses, specifically to a bus safety stopping warning device. Background Technology
[0002] Buses, also known as urban public buses and trolleybuses, are passenger vehicles that operate on urban roads according to fixed routes, fixed times, and fixed stops. They are mainly used to meet the daily travel needs of citizens and are public transportation tools that can provide convenient and economical travel services for the general public.
[0003] Currently, a significant portion of bus passengers are elderly. Since bus stops are typically located on platforms at a certain height above the ground, while this doesn't significantly impact younger passengers, it requires the elderly to walk from the bus to the ground and then back up to the platform to disembark, which is inconvenient for them. The same applies when boarding. To minimize this inconvenience, bus drivers generally try to position the bus as close to the platform as possible, allowing the elderly to easily access the bus directly from the platform. However, this close proximity to the bus tests the driver's experience and driving skills, requiring them to pay close attention to the platform, which can be quite demanding and inconvenient for the driver.
[0004] Therefore, existing technologies need further improvement and enhancement. Utility Model Content
[0005] This application provides a bus safety stopping warning device to solve the problems in the prior art, such as the inconvenience for the elderly to get on and off the bus when it stops at the bus stop, the difficulty for the driver to judge the distance between the bus and the bus stop with the naked eye, the inconvenience of operation, and the heavy workload of the driver.
[0006] The technical solution adopted in this application is as follows:
[0007] This application provides a bus safety stop warning device, which is installed at the lower end of the front door of the bus and includes a mounting component, a radar component, and a control component. The two ends of the mounting component are respectively connected to the bus chassis and the radar component. The radar component includes a radar mounting bracket and a detection radar. The detection radar is connected to the control component. The control component includes a control box and an alarm element. The control box is respectively connected to the alarm element and the detection radar. The power supply terminal of the control box is connected to the right turn input terminal of the bus.
[0008] In a preferred embodiment of this application, the mounting assembly includes a fixing plate and an adjusting column. The fixing plate is connected to the bus, and the two ends of the adjusting column are respectively connected to the fixing plate and the radar mounting bracket.
[0009] In a preferred embodiment of this application, the fixing plate is detachably connected to the bus, and the adjusting column and the fixing plate are threaded together.
[0010] In a preferred embodiment of this application, the alarm device is installed on the driver's cab of the bus.
[0011] In a preferred embodiment of this application, the control box includes a power supply terminal, an alarm terminal, and a radar terminal. The radar terminal is connected to a detection radar, the alarm terminal is connected to an alarm device, and the power supply terminal is connected to the right turn output terminal of the bus's power distribution panel.
[0012] In a preferred embodiment of this application, the detection radar has a warning range and a danger range. In the warning range, the distance between the detection radar and the platform is 0.5m to 0.9m, and in the danger range, the distance between the detection radar and the platform is no more than 0.4m.
[0013] In a preferred embodiment of this application, the sound intensity and frequency of the alarm device increase as the distance from the warning range to the danger range changes from the bus.
[0014] Due to the adoption of the above technical solution, the technical effects achieved by this application are as follows:
[0015] This application provides a bus safety stopping warning device. By installing a radar component at the lower end of the bus's front door, the radar can detect the distance between the bus and the platform in real time as the bus approaches and notify the driver via an alarm. Compared to visual observation, this device is more accurate, reduces driver fatigue, and is more convenient to use. Furthermore, since buses often turn right to approach the platform when stopping, this application connects the power supply of the control box to the bus's right turn input to activate the detection radar during the turn. This not only saves energy but also adapts to the driving and stopping habits of buses. Moreover, connecting the power supply of the control box to the bus's right turn input also allows for timely reminders to the driver when other vehicles approach the bus while it is turning during normal driving, thereby improving driving safety to a certain extent.

[0029] like Figures 1 to 3 As shown, this application provides a bus safety stop warning device. The safety stop warning device is installed at the lower end of the front door of the bus and includes a mounting component 10, a radar component 20, and a control component 30. The two ends of the mounting component 10 are respectively connected to the bus chassis and the radar component 20. The radar component 20 includes a radar mounting bracket 21 and a detection radar 22. The detection radar 22 is connected to the control component 30. The control component 30 includes a control box 31 and an alarm element 32. The control box 31 is connected to the alarm element 32 and the detection radar 22. The power supply end of the control box 31 is connected to the right turn input end of the bus.
[0030] Among them, such as Figure 1 As shown, the radar mounting bracket 21 can adopt a positioning structure with a circular cross-section. It can be a conical structure or a columnar structure. The circular cross-section is provided with a mounting slot. The mounting slot can be detachably installed with a detection radar 22. The detection radar 22 can be a radar component with distance detection function to detect the distance between the bus and the platform.
[0031] The mounting assembly 10 may include a fixing plate 11 and an adjusting column 12. The fixing plate 11 is connected to the bus, and the two ends of the adjusting column 12 are respectively connected to the fixing plate 11 and the radar mounting bracket 21. The fixing plate 11 is detachably connected to the bus, and the adjusting column 12 and the fixing plate 11 are threaded together.
[0032] like Figure 1 As shown, the fixing plate 11 is a block structure with a threaded hole in its top area. The fixing plate is placed on the bus chassis by screws or studs. The structure of the adjusting column 12 can adjust the stud. The surface of the fixing plate 11 is provided with a nut structure. By rotating the stud, the adjusting column 12 can move towards the top of the fixing plate 11 or away from the fixing plate 11, thereby realizing the vertical adjustment of the radar mounting bracket 21 to adapt to different height requirements.
[0033] In a preferred embodiment of this application, the alarm element 32 is installed in the driver's cab of the bus. It is understood that the alarm element 32 can employ a common buzzer structure, receiving signals from the detection radar 22 and triggering an alarm based on the distance between the detection radar 22 and the bus stop, thereby reminding the driver of the distance between the bus and the bus stop.
[0034] Optionally, to improve the effectiveness of the alarm 32, a light emission effect can be added in addition to the sound emission, so that when the bus approaches the station, the alarm 32 can not only remind the driver with sound, but also attract the driver's attention with flashing lights, thereby improving the alert effect.
[0035] In a preferred embodiment, the control box 31 includes a power supply terminal 311, an alarm terminal 312, and a radar terminal 313. The radar terminal 313 is connected to the detection radar 22, the alarm terminal 312 is connected to the alarm device 32, and the power supply terminal 311 is connected to the right turn output terminal of the bus power distribution panel 314. It should be noted that the detection radar 22 has a warning range and a danger range. In the warning range, the distance between the detection radar 22 and the platform is 0.5m-0.9m, and in the danger range, the distance between the detection radar 22 and the platform is no more than 0.4m.
[0036] Furthermore, the sound intensity and frequency of the alarm 32 increase as the distance from the warning range to the danger range changes from the bus.
[0037] Understandably, the control box 31 can be installed inside the bus chassis for easy protection. During actual driving, when the bus needs to stop at the next station, it needs to move closer to the station. In this case, the bus driver will turn on the right turn signal to alert pedestrians and vehicles on the road. At this time, since the power supply terminal 311 of the control box 31 is connected to the right turn input terminal of the bus power distribution panel 314, the control box 31 will also be energized when the right turn input terminal of the power distribution panel 314 is energized. The detection radar 22 can then be energized and operate, continuously judging the distance between the detection radar 22 and the station. As the vehicle gradually approaches the station, the detection radar 22 detects the gradually decreasing distance and transmits this distance detection information. The signal is transmitted to control box 31, which processes the signal in real time and transmits it to alarm device 32. Alarm device 32 then emits an alarm sound that gradually increases in volume and frequency as the distance gradually decreases, reminding the driver that the distance between the bus and the platform is gradually shortening. When the sound reaches its maximum and the alarm frequency is the fastest, it means that the distance between the platform and the bus has reached its limit, indicating that the bus has stopped. Passengers can then step onto the platform or board the bus from the edge of the platform, providing convenience for passengers with mobility impairments or the elderly. This reduces the workload of the bus driver, who needs to concentrate on observing and judging the distance to the platform during the stopping process, thereby reducing the driver's burden and improving the quality and efficiency of their work.
[0038] Of course, it should be noted that the control system and control structure within the control box 31 can be controlled using a common microcontroller architecture, and the control system can also be set using a common distance alarm program. Therefore, this application does not impose specific limitations on the microcontroller, the detection radar 22, and the control program; similarly, the connection between the control box 31 and the bus power distribution panel 314 and the alarm device 32, such as Figure 2 As shown, a line can be used for connection, so that signals can be transmitted and processed between various structures. Of course, in order to improve the level of intelligence and the convenience of installation, wireless connection can also be used for signal transmission and reception. This application does not make specific limitations here.
[0039] Furthermore, for the structure of the adjustment column 12, an electrically controlled lifting rod or rotating rod can be used to intelligently control the position of the detection radar 22. Although the cost and installation complexity increase, the level of intelligence is higher.
