Description

Technical Field

[0001] This invention relates to the field of traffic safety technology, specifically to an automated drunk driving detection robot. Background Technology

[0002] Driving under the influence of alcohol or alcoholic beverages refers to controlling and driving a motor vehicle, sometimes including bicycles, vehicles or machinery with engines or electric motors, and horseback riding. It is a leading cause of death in traffic accidents and is considered a traffic violation in many countries, even a crime. The rumor that drinking large amounts of water or chewing gum can help you evade a breathalyzer test is false and unreliable. Driving under the influence of alcohol impairs safe driving ability and greatly increases the risk of accidents. In criminal law, it is considered to fall under the category of "caused negligence," which means "foreseeing that an event will occur but being certain that it will not occur and failing to take precautions."

[0003] In current traffic management, drunk driving checks and document inspections typically rely on manual checks by traffic police. This traditional method has many drawbacks: first, manual checks are inefficient and easily cause traffic congestion; second, there is a risk of missed checks, as it cannot comprehensively cover all vehicles; and third, it requires a large number of police officers, increasing enforcement costs. With the increasing traffic flow, traditional manual checks can no longer meet the needs of modern traffic management. Therefore, there is an urgent need for a robot that can automatically complete drunk driving checks and document inspections to improve the speed and quality of checks, reduce traffic congestion, and reduce the need for police manpower. Summary of the Invention

An electric telescopic rod is fixedly connected to the surface of the first slider, and a horizontal plate is fixedly connected to the output end of the electric telescopic rod. An alcohol detector is fixedly connected to one side of the surface of the horizontal plate, and a recycling box is fixedly connected to one side of the second slider.

[0006] Preferably, the surface of the information processing box is provided with through grooves that are compatible with the ID card placement plate, the vehicle registration plate, and the driver's license placement plate, and both sides of the surface of the information processing box are provided with through holes that are compatible with the first toothed plate.

[0008] Preferably, the first slider is located above the second gear and the second slider is located below the third gear. Fixed blocks are fixedly connected to the top and bottom of both sides of the vertical plate, and a sliding rod is fixedly connected between the opposite sides of the two fixed blocks. A movable block is slidably connected to the surface of the sliding rod, and one side of the first slider and the second slider are fixedly connected to one side of the movable block through an L-shaped plate.

[0009] Preferably, the top and bottom ends of the first and second threaded rods are rotatably connected to positioning plates, and the back of the positioning plates is fixedly connected to the surface of the vertical plate.

[0013] This invention provides an automated drunk driving detection robot. Compared with existing technologies, it has the following advantages: This automated drunk driving detection robot, through the precise coordination of connecting plates, horizontal plates, and alcohol detectors, can accurately extend the alcohol detector into the driver's cabin for detection, ensuring the accuracy of the test results. Inside the information processing box, the ID card, vehicle registration, and driver's license placement plates can be moved out to allow the driver's ID card, vehicle registration, and driver's license to be placed into the information processing box for verification. Simultaneously, the alcohol detector and the collection box move in opposite directions driven by a motor. When the ID card, vehicle registration, and driver's license placement plates are retracted into the information processing box, the alcohol detector and the collection box move in opposite directions. While the documents are being checked, the driver can use the moving alcohol detector to test their blood alcohol content. If the blood alcohol content exceeds the legal limit, an alarm will be triggered on top. The warning lights on the back of the vertical plate can alert oncoming vehicles. When the entire device is used in the oncoming lane, the vertical plate can rotate to conduct a breathalyzer test on vehicles traveling in the opposite lane. The device can quickly and accurately complete breathalyzer checks and document inspections, effectively avoiding traffic congestion caused by manual checks. This is of great significance for alleviating urban traffic pressure and improving road capacity. It has a high degree of automation and can autonomously complete most of the query and processing work, thereby greatly reducing the need for police manpower. This helps to reduce the workload of traffic police and improve law enforcement efficiency. Attached Figure Description

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] In use, the walking mechanism 1 moves to the side of the vehicle for which a drunk driving check is required. The driver places his ID card, vehicle registration certificate, and driver's license on the ID card placement plate 12, vehicle registration certificate placement plate 13, and driver's license placement plate 14, respectively. The dual-head motor 5 is started, which drives the fixed rod 6 to rotate. The first pulley 7 on the surface of the fixed rod 6 drives the second pulley 9 to rotate under the transmission of the belt. The second pulley 9 drives the movable rod 8 to rotate. The first gear 15 on the movable rod 8 drives the first tooth plate 16 to move into the information processing box 4. The fixed plate 11 brings the ID card placement plate 12, vehicle registration certificate placement plate 13, and driver's license placement plate 14 back into the information processing box 4. At the same time, the second toothed plate 20 will drive the second gear 21 and the third gear 22 to rotate. The second gear 21 will drive the first threaded rod 17 to rotate, and the third gear 22 will drive the second threaded rod 18 to rotate. The first threaded rod 17 will drive the first slider 23 to move downward. The first slider 23 will move the alcohol detector 27 downward. Then, the electric telescopic rod 25 will be activated. The electric telescopic rod 25 will push the horizontal plate 26 towards the driver's cab. The driver will take a disposable breathalyzer sleeve 41 from the inside of the placement box 40 and put it on the alcohol detector 27 to test the alcohol content, and the test will be broadcast through the electronic broadcast screen 39. If the alcohol content exceeds the limit, the alarm 38 will sound an alarm to alert the traffic police to handle the situation. The second threaded rod 18 drives the second slider 24 to move upward, which in turn moves the recycling box 28 upward, allowing the used disposable inhalation sleeve 41 to be placed into the recycling box 28. After the test is completed, the dual-head motor 5 reverses, and the alcohol detector 27 and the recycling box 28 move in opposite directions to return to their original positions. At the same time, the ID card placement plate 12, vehicle registration plate 13, and driver's license placement plate 14 inside the information processing box 4 are removed from the information processing box 4. Drivers without violations can retrieve their documents, while those with violations have their documents handed over to the traffic police for processing. The second motor 47 on the back of the vertical plate 3 drives the connecting plate 48 to rotate, which in turn drives the blue warning light 50 to rotate. The red warning light 51 and the blue warning light 50 alternate, reminding oncoming vehicles to slow down.
