Description
Technical Field
[0001] The present invention belongs to the technical field of vehicle mounting accessories, and relates to an intelligent pedal structure, in particular to an intelligent pedal structure, a pedal control method using the intelligent pedal structure, and a bus having the intelligent pedal structure. Background Art
[0002] At present, for most low-floor buses, in order to facilitate wheelchairs to get on and off the vehicle, the vehicle is usually equipped with a manual flip step or a folding guide plate. Among them, the manual flip step is installed by fixing one part directly on the frame, and when in use, the other part is flipped around the rotation axis and supported on the ground by pulling the buckle; while the folding guide plate is temporarily overlapped on the edge of the vehicle door opening when in use, and can be removed after use, but the operation is more troublesome, and the step (or guide plate) needs to be manually unfolded and stored.
[0003] The patent application (CN202410145074.8) discloses a medical unmanned stretcher and wheelchair transfer vehicle. The guide plates for getting on and off the stretcher and wheelchair are controlled by the automatic driving control system to be retracted or extended, and voice reminders are given through the voice reminder module. An ultrasonic sensor is set at the front end of the guide plate. When the front end of the guide plate encounters an obstacle during the extension process, the ultrasonic sensor will send information to the sensor detection device, and the sensor detection device will then process the information and send it to the automatic driving control system. The automatic driving control system controls the guide plate to be retracted to avoid accidents.
[0004] It can be seen from the above-mentioned patent that by installing an ultrasonic sensor at the front end of the guide plate, the situation of the front end of the guide plate during the unfolding process can be detected in real time. However, the working environment of the guide plate is a relatively complex environment. It is not only necessary to detect whether the front end of the guide plate will encounter obstacles during the unfolding process, but also to detect whether there are non-motor vehicles or pedestrians approaching on both sides of the guide plate, so as to avoid collision with the guide plate during the unfolding or retracting process. Obviously, the above-mentioned patent cannot realize the detection of the directions on both sides of the guide plate. Summary of the invention
[0005] The purpose of the present invention is to address the above problems in the existing technology and to propose an intelligent pedal structure that can detect whether there are non-motor vehicles or pedestrians approaching the front and rear directions of the vehicle, and whether there are obstacles directly in front of the side of the vehicle.

When the second distance is 0m, the flap stops rotating; the visual sensor is used to detect whether there are obstacles on the roadbed or the ground.
[0013] In the above-mentioned intelligent pedal structure, there are multiple ranging sensors on the second side and the fourth side, and they are arranged in a line along the length direction of the corresponding side.

[0014] In the above-mentioned intelligent pedal structure, multiple pressure sensors are arranged on the flap, and the multiple pressure sensors are respectively located at various corners of the flap. When the pressure sensor detects that the pressure on the flap is greater than the preset pressure, the flap does not work, and the preset pressure is 5-10N.
[0015] In the above-mentioned intelligent pedal structure, a light-emitting module is provided on one or more of the second side, the third side and the fourth side, and the light-emitting module is installed at the edge of the corresponding side, wherein the ranging sensor and the visual sensor on the corresponding side are installed on the light-emitting module.

[0019] The driving motor is installed on the fixed plate and serves as the power source when the flap is opened or closed;
[0020] The execution module has one end connected to the output end of the driving motor and the other end connected to the flap through a hinge, wherein the driving motor drives the execution module to realize the unfolding of the flap or folding and storing it on the fixed plate.
[0021] In the above-mentioned intelligent pedal structure, the distance measuring sensor is arranged on the third side portion, and the relative distance between the third side portion and the roadbed or the ground is detected by the distance measuring sensor, and the relative distance is the second distance. When the second distance is 0m, the flap stops rotating; or the distance measuring sensor and the visual sensor are arranged on the third side portion, and the relative distance between the third side portion and the roadbed or the ground is detected by the distance measuring sensor, and the relative distance is the second distance. When the second distance is 0m, the flap stops rotating; the visual sensor is used to detect whether there are obstacles on the roadbed or the ground.
[0022] The present invention also provides a pedal control method using the intelligent pedal structure, comprising the steps of:
[0023] S1: Detect whether the pressure on the flap exceeds the preset pressure through the pressure sensor. If it exceeds the preset pressure, an alarm is triggered to inform the bus driver, who then asks the corresponding passenger to remove the foreign object or person from the flap or walk away through the voice module in the bus; if it is lower than the preset pressure, execute step S2;
[0024] S2: The bus driver presses the control button on the bus to control the drive motor to drive the flap to rotate through the execution module. When the flap is flipped to a certain angle, a part of the flap is located outside the bus. At this time, the distance sensor and visual sensor corresponding to this part work.
[0025] S3: When the visual sensor located on the second side portion or the fourth side portion detects that there is a non-motorized vehicle or pedestrian behind or in front of the bus, and the distance between the non-motorized vehicle or pedestrian and the corresponding side portion is detected by the distance measuring sensor to be constantly reduced, when the relative distance is less than the preset distance, step S4 is executed; when the visual sensor located on the third side portion detects that there is an obstacle on the roadbed or the ground, step S5 is executed; when the distance measuring sensor located on the third side portion detects that the relative distance between the side portion and the roadbed or the ground is 0m, step S6 is executed;
[0026] S4: the flap stops rotating and an alarm is sounded to inform the bus driver.

When the bus driver finds through the front windshield or rearview mirror that the non-motorized vehicle or pedestrian has stopped, and the relative distance between the ranging sensor on the corresponding side and the non-motorized vehicle or pedestrian does not change, the bus driver presses the control button again to rotate the flap again. When the ranging sensor on the third side detects that the relative distance between the side and the roadbed or the ground is 0m, step S6 is executed;
[0027] S5: The flap stops rotating and an alarm is sounded to inform the bus driver.

DETAILED DESCRIPTION
[0036] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0037] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0038] like Figures 1 to 3 As shown, the present invention provides an intelligent pedal structure, comprising:
[0039] The fixing plate 10 is located in the bus and is mounted on the bus floor, or is integrally arranged with the bus floor;
[0040] The flap 20 is provided with a first side portion 21, a second side portion 22, a third side portion 23 and a fourth side portion 24 in sequence along the edge of the flap 20, and the first side portion 21 is arranged opposite to the third side portion 23, and the second side portion 22 is arranged opposite to the fourth side portion 24, wherein the first side portion 21 is rotatably connected to the fixed plate 10 through a hinge, and the second side portion 22 and the fourth side portion 24 are respectively provided with a distance measuring sensor 30, and a relative distance is formed between the side where the distance measuring sensor 30 is located and a non-motor vehicle or pedestrian on the straight moving path of the bus, and the distance is a first distance, and when the first distance is less than the preset distance, the flap 20 stops flipping, and the angle between the flap 20 and the fixed plate 10 remains unchanged;
[0041] A driving motor 40 is mounted on the fixed plate 10 and serves as a power source when the flap 20 is opened or retracted;
[0042] The execution module 50 has one end connected to the output end of the driving motor 40 and the other end connected to the flap 20 via a hinge, wherein the driving motor 40 drives the execution module 50 to unfold the flap 20 or fold it to be stored on the fixed plate 10.
[0043] In the prior art, an ultrasonic sensor is provided at the front end of the flap 20 to detect whether there is an obstacle on the roadbed or the ground during the flap 20 flipping. If there is an obstacle, the flap 20 stops flipping, and flips again after the obstacle is removed. However, the flap 20 cannot detect whether there is a non-motorized vehicle or pedestrian approaching on the straight path of the bus during the rotation process, so there is still a risk of non-motorized vehicles or pedestrians colliding with the flap 20 during the flipping process.
[0044] Therefore, in an intelligent pedal structure provided by the present invention, ranging sensors 30 are arranged on both sides of the flap 20 to detect non-motor vehicles or pedestrians in the front and rear directions on the straight-line travel path of the bus, so as to avoid collision between the non-motor vehicles or pedestrians and the flap 20 during the flipping process, thereby improving the safety of the flap 20 during the flipping process.
[0045] It is worth mentioning that the distance measuring sensor 30 is generally an infrared sensor, which can monitor in real time the relative distance between non-motor vehicles or pedestrians and the flap 20 in the front and rear directions of the bus. When the relative distance is less than the preset distance, the flap 20 stops rotating, wherein the preset distance is generally about 20m.
[0046] In addition, a voice module and an alarm module are provided in the bus. When the non-motorized vehicle or pedestrian enters the preset distance, the flap 20 stops rotating. At this time, the alarm module in the bus sends an alarm signal, and the control system in the bus controls the voice module to send a voice reminder to inform the non-motorized vehicle or pedestrian to stop moving. When the bus driver finds through the front windshield or rearview mirror that the non-motorized vehicle or pedestrian has stopped, and the relative distance between the ranging sensor 30 on the corresponding side and the non-motorized vehicle or pedestrian does not change, the bus driver presses the control button again to make the flap 20 rotate again until the flap 20 contacts the roadbed or the ground, and then the drive motor 40 stops rotating, and the flap 20 is in a fully expanded state. At this time, passengers in need can board the bus through the flap 20. After the passengers get on the bus, the driver controls the drive motor 40 to reverse through the control button again, prompting the flap 20 to rotate, and finally stacked on the fixed plate 10. The flap 20 is already in a complete state.
[0047] In this embodiment, when the flap 20 contacts the roadbed or the ground, the roadbed or the ground will form a blockage for the flap 20, and after the signal formed by the blockage is transmitted to the control system of the bus, the drive motor 40 will be stopped.
[0048] It is further pointed out that during the unfolding process of the flap 20, when the flap 20 is located inside the bus, the distance measuring sensor 30 located on the side corresponding to the flap 20 does not work; when a part of the flap 20 is exposed outside the bus, the distance measuring sensor 30 on the side corresponding to the part starts to work, and as the exposed area of the flap 20 outside the bus increases, the number of working distance measuring sensors 30 corresponding to the exposed area gradually increases.
[0049] In this embodiment, when the flipping angle of the flap 20 is between 85° and 95°, a portion of the flap 20 begins to be exposed outside the bus. At this time, the ranging sensor 30 of this portion starts to work. As the exposed area of the flap 20 increases, the number of working ranging sensors 30 gradually increases until all are turned on. This ensures that the flap 20 does not stop due to false triggering during the flipping process, thereby improving the reliability of the flap 20 when in use.
[0050] It is worth mentioning that the number of the ranging sensors 30 on the second side portion 22 and the number of the ranging sensors 30 on the fourth side portion 24 are both multiple, and they are arranged in a line along the length direction of the corresponding side portions, wherein the ranging sensors 30 on the second side portion 22 are used to monitor non-motor vehicles or pedestrians in the straight line direction behind the bus in real time, and the ranging sensors 30 on the fourth side portion 24 are used to monitor non-motor vehicles or pedestrians in the straight line direction in front of the bus in real time.
[0051] Further preferably, in addition to the distance measuring sensor 30, a visual sensor 60 can also be installed on the second side portion 22 and the fourth side portion 24. The visual sensor 60 can monitor non-motorized vehicles or pedestrians in the front and rear directions of the bus in real time, and further predict the relative distance between the non-motorized vehicles or pedestrians and the flap 20 in the front and rear directions of the bus.
[0052] It is worth mentioning that the visual sensor 60 installed on the side forms a fan-shaped radiation area with a rated range as a radius. When a non-motor vehicle or a pedestrian appears in the fan-shaped radiation area, and the first distance between the non-motor vehicle or the pedestrian and the side where the ranging sensor 30 is located is less than the preset distance, the flap 20 stops rotating, and the angle between the flap 20 and the fixed plate 10 remains unchanged.
[0053] In addition, the visual sensor 60 is a camera.
[0054] It is further pointed out that the number of cameras can be two. When the two cameras are installed on the second side 22, the multiple ranging sensors 30 located on the second side 22 are located between the two cameras. When the two cameras are installed on the fourth side 24, the multiple ranging sensors 30 located on the fourth side 24 are located between the two cameras.
[0055] In this embodiment, the reason why two cameras are arranged at both ends of a plurality of ranging sensors 30 arranged in a row is to reduce the intersection area of the radiation of the two cameras, thereby expanding the visual radiation range, and further improving the reliability of the flap 20 during the rotation process.
[0056] Preferably, a distance measuring sensor 30 is provided on the third side portion 23, and the relative distance between the third side portion 23 and the roadbed or the ground is detected by the distance measuring sensor 30, and the relative distance is the second distance. When the second distance is 0m, the flap 20 stops rotating; or a distance measuring sensor 30 and a visual sensor 60 are provided on the third side portion 23, and the relative distance between the third side portion 23 and the roadbed or the ground is detected by the distance measuring sensor 30, and the relative distance is the second distance. When the second distance is 0m, the flap 20 stops rotating; and the visual sensor 60 is used to detect whether there are obstacles on the roadbed or the ground.
[0057] It is worth mentioning that the distance sensor 30 is provided on the third side portion 23 to ensure that when the flap 20 contacts the roadbed or the ground, if the drive motor 40 does not stop rotating, the flap 20 will be squeezed and damaged. Therefore, the distance sensor 30 is provided to further ensure that the drive motor 40 can reliably stop rotating after the flap 20 is flipped into place, thereby ensuring the safety of the flap 20. The visual sensor 60 is provided on the third side portion 23 to detect whether there is an obstacle on the roadbed or the ground. If there is an obstacle on the roadbed or the ground, the flap 20 stops rotating and an alarm is sounded to inform the bus driver. The bus driver issues a voice reminder to the passengers on the platform through the voice module in the bus, informing the passengers to remove the obstacle. When the visual sensor 60 detects that there is no obstacle on the third side portion 23, the bus driver presses the control button again to rotate the flap 20 again until the flap 20 is fully opened.
[0058] Preferably, a plurality of pressure sensors 70 are provided on the flap 20, and the plurality of pressure sensors 70 are respectively located at various corners of the flap 20, wherein when the pressure sensor 70 detects that the pressure on the flap 20 is greater than a preset pressure, the flap 20 does not work, and the preset pressure is 5-10N.
[0059] In this embodiment, the pressure sensor 70 is provided on the flap 20 in order to realize reliable opening and reliable rotation of the flap 20 .
[0060] Preferably, a light emitting module 80 is provided on one or more of the second side 22, the third side 23 and the fourth side 24, and the light emitting module 80 is installed at the edge of the corresponding side, wherein the ranging sensor 30 and the visual sensor 60 on the corresponding side are installed on the light emitting module 80.
[0061] It is worth mentioning that the light-emitting module 80 is generally set up when passengers get off or go up from the unfolded flap 20, and the light-emitting module 80 works to remind passengers to pay attention to safety when getting on and off the bus, and the light-emitting module 80 is in a flashing state. In addition, when the bus reaches a darker road section, the light-emitting module 80 can also illuminate the alighting passage, making it convenient for passengers to get on and off the bus safely.
[0062] Preferably, the fixed plate 10 includes a fixed plate front side 11 and a fixed plate back side 12, and the drive motor 40 is installed on the fixed plate back side 12, and the fixed plate 10 is installed on the bus floor through the fixed plate back side 12, the flap 20 includes a flap front side 25 and a flap back side 26, and the execution module 50 includes an active connecting rod 51 and a driven connecting rod 52 hinged to each other, wherein one end of the active connecting rod 51 passes through the fixed plate 10 and is connected to the drive connection, and one end of the driven connecting rod 52 is connected to the flap front side 25 through a hinge.
[0063] Further preferably, a torsion spring handle 90 is also provided on the back side 26 of the flap. When the smart pedal structure is in a power-off state, the flap 20 can be manually rotated by the torsion spring handle 90 to realize the use of the smart pedal structure.
[0064] The present invention also provides a pedal control method using an intelligent pedal structure, comprising the steps of:
[0065] S1: Detecting whether the pressure on the flap 20 exceeds the preset pressure through the pressure sensor 70. If it exceeds the preset pressure, an alarm is sounded to inform the bus driver, who then asks the corresponding passenger to remove the foreign object or person from the flap 20 or walk away through the voice module in the bus; if it is lower than the preset pressure, executing step S2;
[0066] S2: The bus driver presses the control button on the bus to control the driving motor 40 to drive the flap 20 to rotate through the execution module 50. When the flap 20 flips over a certain angle, a part of the flap 20 is located outside the bus. At this time, the distance sensor 30 and the visual sensor 60 corresponding to the part work.
[0067] S3: When the visual sensor 60 located on the second side portion 22 or the fourth side portion 24 detects that there is a non-motorized vehicle or pedestrian behind or in front of the bus, and the distance between the non-motorized vehicle or pedestrian and the corresponding side portion is detected by the distance measuring sensor 30 to be constantly reduced, when the relative distance is less than the preset distance, step S4 is executed; when the visual sensor 60 located on the third side portion 23 detects that there is an obstacle on the roadbed or the ground, step S5 is executed; when the distance measuring sensor 30 located on the third side portion 23 detects that the relative distance between the side portion and the roadbed or the ground is 0m, step S6 is executed;

If it exceeds the preset pressure, an alarm is triggered to inform the bus driver, who then asks the corresponding passenger to remove the foreign object or person from the flap or walk away through the voice module in the bus; if it is lower than the preset pressure, execute step S2; S2: The bus driver presses the control button on the bus to control the drive motor to drive the flap to rotate through the execution module. When the flap is flipped to a certain angle, a part of the flap is located outside the bus. At this time, the distance sensor and visual sensor corresponding to this part work. S3: When the visual sensor located on the second side portion or the fourth side portion detects that there is a non-motorized vehicle or pedestrian behind or in front of the bus, and the distance between the non-motorized vehicle or pedestrian and the corresponding side portion is detected by the distance measuring sensor to be constantly reduced, when the relative distance is less than the preset distance, step S4 is executed; when the visual sensor located on the third side portion detects that there is an obstacle on the roadbed or the ground, step S5 is executed; when the distance measuring sensor located on the third side portion detects that the relative distance between the side portion and the roadbed or the ground is 0m, step S6 is executed; S4: the flap stops rotating and an alarm is sounded to inform the bus driver. The bus driver issues a voice reminder to the non-motorized vehicle or pedestrian through the voice module in the bus. When the bus driver finds through the front windshield or rearview mirror that the non-motorized vehicle or pedestrian has stopped, and the relative distance between the ranging sensor on the corresponding side and the non-motorized vehicle or pedestrian does not change, the bus driver presses the control button again to rotate the flap again. When the ranging sensor on the third side detects that the relative distance between the side and the roadbed or the ground is 0m, step S6 is executed; S5: The flap stops rotating and an alarm is sounded to inform the bus driver. The bus driver issues a voice reminder to the passengers on the platform through the voice module in the bus, informing the passengers to remove the obstacles. When the visual sensor on the third side detects that there is no obstacle, the bus driver presses the control button again to rotate the flap again. When the distance measuring sensor on the third side detects that the relative distance between the side and the roadbed or the ground is 0m, step S6 is executed. S6: the driving motor stops rotating and the flap is in a fully extended state. Passengers in need can get on and off the bus through the flap. When the passengers get on or off the bus, the driver controls the driving motor to reverse by the control button again, causing the flap to rotate and finally stack on the fixed plate.
