Description

Technical fields:

[0001] This utility model relates to the field of driving safety control technology, specifically to a forklift driving safety control device. Background technology:

[0002] Forklifts are industrial material handling vehicles, referring to various wheeled handling vehicles used for loading, unloading, stacking, and short-distance transport of palletized goods, playing a vital role in people's daily production and life. However, firstly, due to drivers' unsafe driving behaviors, such as using mobile phones while driving, smoking, driving while fatigued, or driving under the influence of alcohol, or other personnel without proper authorization controlling the vehicle's start, accidents involving collisions with pedestrians or obstacles, leading to goods falling or vehicles overturning, occur frequently. Secondly, although factory regulations have equipped each forklift with an alcohol tester, to ensure that drivers of different heights can perform tests, currently, the alcohol tester can only be placed on the control panel in the cab or suspended inside the cab by a rope, without a fixed position. When the alcohol tester is placed on the control panel, the vehicle's movement and bumps can easily cause it to slip and fall due to inertia, affecting the detection; when the alcohol tester is suspended by a rope, the vehicle's movement and bumps can easily cause the alcohol tester to swing and hit the inner wall of the cab, even posing a danger to the driver.

[0003] Therefore, in order to ensure the safe use of forklifts, a forklift driving safety control device needs to be developed. Utility Model Content:

[0004] The purpose of this invention is to provide a forklift driving safety control device.

[0005] This utility model is implemented by the following technical solution: a forklift driving safety control device, which includes a cab, a mast and forks, wherein the mast is installed in front of the cab and the forks are installed on the mast; it also includes a vehicle-mounted camera, an alcohol detector, a mounting base, a seat pressure sensor, a speed sensor, a safety warning module, an alarm module, a vehicle braking module and a vehicle-mounted safety driving host installed on the center console in the cab;

[0006] The vehicle-mounted camera is installed directly above the driver's seat, and a mounting bracket is fixed on the inner wall of the driver's cabin near the driver's seat. The alcohol detector is installed in the mounting bracket, and the seat pressure sensor is installed below the driver's seat. The safety warning module is installed inside the driver's cabin, and the alarm module is installed outside the driver's cabin.

[0007] The vehicle-mounted safety driving host integrates a microprocessor. The signal output terminals of the vehicle-mounted camera, the alcohol detector, the seat pressure sensor, and the speed sensor are respectively connected to the signal input terminal of the microprocessor. The control terminal of the microprocessor is respectively connected to the controlled terminals of the safety warning module, the alarm module, and the vehicle braking module.

[0008] Preferably, the mounting base includes a U-shaped frame, a U-shaped limiting plate, and a first magnet block; two parallel U-shaped grooves are formed on the inner wall of the U-shaped frame, and the two U-shaped limiting plates are respectively placed on the front and rear opening sides of the U-shaped frame and inserted into the corresponding U-shaped grooves to form an installation space; the first magnet blocks are respectively fixed on the opposite inner walls of the U-shaped frame, and second magnet blocks are respectively fixed on the opposite outer walls of the alcohol detector, the alcohol detector is placed in the installation space, and the second magnet blocks are respectively attracted to the corresponding first magnet blocks; a through hole is formed at the center of the bottom of the U-shaped frame, the bottom end of the spring wire passes through the through hole and is fixedly connected to the limiting ball, and the top end of the spring wire is fixedly connected to the bottom of the alcohol detector.

[0014] The advantages of this utility model are as follows: First, this utility model includes a vehicle-mounted camera, an alcohol detector, a seat pressure sensor, and a microprocessor for a vehicle-mounted safety driving host. The vehicle-mounted camera uses facial recognition technology to determine driver authorization, the alcohol detector determines whether the driver is driving under the influence of alcohol, and the seat pressure sensor determines whether the driver is in a normal driving position. When the microprocessor receives a message from the vehicle-mounted camera indicating a failed facial recognition scan, or from the alcohol detector or seat pressure sensor indicating an abnormality, the microprocessor sends a command to the vehicle braking module. The vehicle braking module then engages the vehicle brakes, preventing the vehicle from being started by the key, thus avoiding potential safety hazards. Furthermore, during driving... The vehicle-mounted camera simultaneously monitors the driver's face and hands to determine if the driver is using a mobile phone, smoking, or driving while fatigued. When the microprocessor receives information about fatigued or improper driving detected by the vehicle-mounted camera, it sends a command to the safety alert module, which then issues a voice prompt and a vibrator to provide a vibration alert. If the alert is ineffective and the driver continues to deal with fatigue, the microprocessor sends a command to the alarm module, which then issues a warning. If the driver's fatigue does not improve, the microprocessor controls the vehicle's braking module to automatically engage the brakes based on driving data sent by the speed sensor, bringing the vehicle to a safe stop and ensuring driving safety.

[0015] Secondly, the alcohol detector of this utility model is installed in the mounting base through a second magnet, a spring wire, and a limiting ball. The mounting base includes a U-shaped frame, a U-shaped limiting plate, and a first magnet.

Furthermore, the two U-shaped limiting plates are respectively inserted into the U-shaped grooves of the U-shaped frame, which facilitates disassembly and cleaning. Attached image description:

[0025] The vehicle-mounted camera 4 is installed directly above the driver's seat. The camera 4 uses facial recognition to confirm the driver's identity and identify whether the driver is fatigued or driving improperly. A mounting base 6 is fixed to the inner wall of the driver's cabin 1 near the driver's seat. The mounting base 6 includes a U-shaped frame 6.1, a U-shaped limiting plate 6.2, and a first magnet 6.3. Two parallel U-shaped grooves 6.1.1 are formed on the inner wall of the U-shaped frame 6.1. The two U-shaped limiting plates 6.2 are respectively placed on the front and rear opening sides of the U-shaped frame 6.1 and inserted into the corresponding U-shaped grooves 6.1.1, forming an installation space. First magnets 6.3 are fixed to the opposite inner walls of the U-shaped frame 6.1. Second magnets 6.3 are fixed to the opposite outer walls of the alcohol detector 5. The alcohol detector 5 is placed in the installation space, and the second magnets 6.3 are attracted to the corresponding first magnets. On block 6.3, the alcohol detector 5 is used to detect whether the driver is under the influence of alcohol when starting the vehicle; a through hole 6.1.2 is provided at the bottom center of the U-shaped frame 6.1, the bottom end of the spring wire 14 passes through the through hole 6.1.2 and is fixedly connected to the limiting ball 15, and the top end of the spring wire 14 is fixedly connected to the bottom of the alcohol detector 5; one of the U-shaped limiting plates 6.2 of the mounting base 6 is fixed to the inner wall of the driver's cabin 1, and the alcohol detector 5 is installed in the mounting base 6 through the second magnet block 13, the spring wire 14 and the limiting ball 15. When the alcohol detector 5 needs to be used, the alcohol detector 5 is pulled out from the mounting base 6, and the alcohol detector 5 can be moved up or down through the spring wire 14 to meet the needs of people of different heights; and the two U-shaped limiting plates 6.2 are respectively inserted into the U-shaped sliding grooves 6.1.1 of the U-shaped frame 6.1, which is convenient for disassembly and cleaning;

[0026] A seat pressure sensor 7 is installed below the driver's seat. The seat pressure sensor 7 detects pressure changes in the driver's seat and transmits seat pressure information to the microprocessor 12.1 to determine whether the driver is in a normal driving position. The safety warning module 9 includes a voice prompter 9.1 and a vibrator 9.2. The voice prompter 9.1 is installed inside the forklift cab 1 and broadcasts voice prompts. The vibrator 9.2 is located on the steering wheel and vibrates to alert the driver that they are fatigued. The alarm module 10 includes an alarm and indicator lights. The alarm module 10 is installed outside the forklift cab 1 and issues an alarm.

[0027] The vehicle-mounted safety driving host 12 integrates a microprocessor 12.1, which is used to receive and output signals. The signal output terminals of the vehicle-mounted camera 4, alcohol detector 5, seat pressure sensor 7, and speed sensor 8 are respectively connected to the signal input terminal of the microprocessor 12.1. The control terminal of the microprocessor 12.1 is respectively connected to the controlled terminals of the safety reminder module 9, alarm module 10, and vehicle braking module 11.

[0028] When the microprocessor 12.1 receives a message from the vehicle camera 4 indicating that the facial recognition is unqualified or from the alcohol detector 5 or the seat pressure sensor 7 indicating abnormal information, the microprocessor 12.1 sends a command to the vehicle braking module 11, which then activates the vehicle brakes to prevent the vehicle from being started by the key, thus avoiding potential safety hazards.

[0029] When the microprocessor 12.1 receives information about fatigued driving or irregular driving detected by the vehicle camera 4, the microprocessor 12.1 sends a command to the safety prompt module 9, the voice prompt device 9.1 broadcasts a voice prompt, and the vibrator 9.2 generates a vibration reminder. If the prompt is ineffective and the driver continues to deal with fatigue, the microprocessor 12.1 sends a command to the alarm module 10, and the alarm module 10 issues a warning. If the driver's fatigue does not improve, based on the driving data sent by the speed sensor 8, the microprocessor 12.1 controls the vehicle braking module 11 to automatically engage the vehicle brakes to bring the vehicle to a safe stop, thereby ensuring driving safety.

[0030] The vehicle-mounted safety driving host 12 also integrates a Beidou positioning module 12.2, a 4G data transmission module 12.3, and a serial port data transmission module 12.4. The Beidou positioning module 12.2 is used to obtain the real-time location information of the vehicle, supports Beidou / GPS dual-mode navigation, determines the accurate location of the vehicle through the satellite positioning system (BD / GPS), and uploads the location data to the network platform for location monitoring, location analysis, and route planning. The 4G data transmission module 12.3 supports data, image, and video transmission. The serial port data transmission module 12.4 supports data input from alcohol detection devices.

[0031] Working process: First, the vehicle-mounted camera 4 captures the driver's face and compares it with the driver's photo stored in the system. The data is then sent to the microprocessor 12.1 for analysis and processing to determine whether the user is qualified to drive. After facial recognition is successful, the driver takes an alcohol test using the alcohol detector 5. The driver pulls the alcohol detector 5 out of the mounting base 6 and moves it up or down via the spring cable 14. After the test is completed, the alcohol detector 5 is inserted back into the mounting base 6. After the alcohol test is passed, the seat pressure sensor 7 detects whether the driver is in a normal driving position. The vehicle can only be started and used when the seat pressure sensor 7 confirms that there is a legal driver.

[0032] Secondly, during driving, the vehicle-mounted camera 4 captures the driver's face and determines whether the driver is fatigued by recognizing facial features, such as yawning, dull eyes, or half-open eyes. Simultaneously, it captures the driver's hands and identifies any bad driving habits through motion recognition, such as answering or making phone calls, smoking, or prolonged single-handed steering wheel operation. This data is sent to the microprocessor 12.1 for analysis and processing. When the microprocessor 12.1 receives information about fatigued or improper driving detected by the vehicle-mounted camera 4, it sends a command to the safety warning module 9. The voice prompt device 9.1 then broadcasts a voice prompt saying "Please drive safely," and the vibrator 9.2 generates a vibration reminder. If the warning is ineffective and the driver remains fatigued, the microprocessor 12.1 sends a command to the alarm module 10, and both the alarm and indicator lights simultaneously sound a warning.

[0033] If the driver's fatigue does not improve, the vehicle braking module 11 will automatically activate the vehicle brakes based on the driving data sent by the speed sensor 8 and the microprocessor 12.1, so as to bring the vehicle to a safe stop and ensure driving safety.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
