Description

TECHNICAL AREA

[0001] The present utility model solution relates to the field of safe driving technology in the automotive sector and relates in particular to an integrated device for preventing drunk driving. TECHNICAL BACKGROUND

[0002] In today's society, the number of motor vehicles is increasing continuously and rapidly. According to the Chinese Ministry of Public Security's Transportation Administration, the total number of motor vehicles in the country reached 435 million at the end of 2024, including 347 million cars. While the increasing prevalence of vehicles has significantly facilitated people's mobility, it has also considerably exacerbated road safety problems. Driving under the influence of alcohol has become a serious threat to life and property.

[0003] In light of the problem of drunk driving, various societal actors have responded actively: Traffic police have significantly increased their enforcement. In 2023 alone, traffic police authorities nationwide recorded a total of 2.615 million cases of drunk driving. At the same time, the media conducted extensive public awareness campaigns on road safety through various channels to raise awareness of the dangers of drunk driving. Despite all these efforts, however, drunk driving remains widespread.

[0004] Currently, enforcement is primarily carried out via checkpoints set up by the traffic police on the roads. However, due to limited human and material resources, as well as time and spatial constraints, real-time monitoring of all vehicles on the road is hardly feasible. In remote areas, police communication is often inadequate, which is why driving under the influence of alcohol is rarely detected in time. Outside of designated enforcement hours, some drivers take their chances and drive despite being under the influence of alcohol, which is illegal.

[0005] Against this background, we present a vehicle system for preventing drunk driving that monitors the condition of drivers in real time while driving and intervenes in a timely manner if necessary, in order to reduce the number of alcohol-related traffic accidents at the source and thus effectively strengthen road safety. CONTENTS OF THE PRESENT APPLICATION(1) Technical problems solved

[0006] To overcome the disadvantages of the existing technology, the present utility model solution provides a vehicle device for preventing drunk driving and thus solves the problems described in the previous section. (2) Technical solution

[0007] To achieve the aforementioned objectives, the present utility model solution implements the following technical solution: A vehicle system for preventing drunk driving, comprising a test frame. A brake pedal and accelerator pedal system are mounted on the front of the frame, each equipped with a brake and accelerator electromagnetic locking element. A warning light module and a breathalyzer module are installed on the left and right sides of the frame. The rear of the experimental frame houses the power supply, a voltage sink module, an open-source main control board, and a first and second relay. The first relay is electrically connected to the brake EMF coil connector, and the second to the accelerator EMF coil connector. The alarm indicator, the breathalyzer module, the power supply, the voltage sink module, and the first and second relays are all electrically connected to the open-source main control board.

[0008] Furthermore, the locking body of the brake switch is mounted on the base of the brake pedal, with the plug of the switch located under the metal pedal of the brake pedal.

[0009] Furthermore, the locking body of the accelerator pedal Emagin connector is attached to the base of the accelerator pedal assembly, with the connector positioned below the metal pedal.

[0010] On the left side of the aforementioned experimental frame, a first mounting bracket is attached, on which the alarm indicator is mounted.

[0011] A second mounting bracket, on which the alcohol test module is mounted, is attached to the right side of the aforementioned experimental frame.

[0012] The alcohol test module also includes a housing and a blow probe. The housing contains a microcontroller with a semiconductor ethane sensor mounted on it, and the blow probe is directly attached to the housing.

[0013] Furthermore, the semiconductor ethane sensor is located in the housing, with the blowpipe and the housing connected to each other.

[0014] In addition, a buzzer and an expansion interface are provided on the open-source main control board. (3) Beneficial effects

[0015] Compared to existing technologies, the present utility model solution offers a vehicle device for preventing drunk driving with the following advantages: During the initial phase of the vehicle's operation, both the brake and accelerator pedals are locked with an electromagnetic locking pin. After the driver enters the vehicle, they must provide a breathalyzer sample to measure the alcohol concentration in their breath. If no alcohol is detected, the vehicle's main control system immediately releases the pedals, allowing the driver to start the vehicle without any problems. However, if alcohol is detected, the electromagnetic safety switch remains locked to prevent drunk driving from the outset. As soon as the driver has an excessive blood alcohol level, the system not only locks the pedals but also immediately activates the vehicle's audible and visual warning system to alert the driver.

[0017] The technical solution according to the exemplary embodiments of the present utility model solution is described clearly and completely below with reference to the accompanying drawings. Obviously, the described exemplary embodiments represent only a portion of the possible embodiments of the present utility model solution, but not its entire range. All further embodiments developed by a person skilled in the art without creative effort are protected under the present utility model. Example

[0018] As in the Fig. As shown, an embodiment of the present utility model application comprises a vehicle device for preventing drunk driving, which includes a test frame 1. A brake pedal system 2 and an accelerator pedal system 3 are mounted at the front of the test frame 1, with a brake and an accelerator electromagnetic coil section 4 and 5, respectively, installed at the positions of the brake pedal system 2 and the accelerator pedal system 3. An alarm indicator lamp 6 and an alcohol test module 7 are mounted on the left and right sides of the test frame 1, respectively. The power supply 8, a voltage reduction module 9, an open-source main control board 10, a first relay 11, and a second relay 12 are installed at the rear of the test frame 1. The first relay 11 and the second relay 12 are electrically connected to the brake electromagnetic coil connector 4 and the accelerator electromagnetic coil connector 5, respectively.During vehicle initialization, the brake and accelerator pedals are locked with an electromagnetic interlock. Once the driver enters the vehicle, they must perform a breathalyzer test using the alcohol test module 7 to measure the alcohol concentration in their breath. If the test result is negative, the main control system immediately commands the pedals to unlock, allowing the driver to start the vehicle without any issues. If the test is positive, however, the electromagnetic interlock remains locked. Driving under the influence of alcohol is prevented at its source. As soon as a driver with an excessive blood alcohol concentration is detected, the system not only automatically disables the pedals but also immediately activates the vehicle's audible and visual warning system to alert the driver.The alarm indicator 6, the alcohol test module 7, the device power supply 8, the voltage reduction module 9, the first relay 11 and the second relay 12 are all electrically connected to the main control board 10.

[0019] How Fig. As shown, in some embodiments the locking body of the brake electromagnet screw 4 is mounted on the base of the brake pedal assembly 2, with the screw's plug located below the metal pedal of the brake pedal assembly 2. The screw model LY-01 primarily serves as an electromagnetic device for controlling the extension and adjustment of the brake pedal.

[0020] How Fig. As shown, in some embodiments the locking body of the accelerator pedal EMF screw 5 is attached to the base of the accelerator pedal assembly 3, with the wrench being located below the metal pedal of the accelerator pedal assembly 3. The accelerator pedal EMF screw model LY-01 is primarily used to control the pedal adjustment or locking.

[0021] How Fig. As shown, in some embodiments a first mounting bracket 13 is attached to the left side of the experimental frame 1, on which the alarm indicator 6 is mounted. This mounting bracket serves to securely fix and hold the indicator in a stable position to prevent displacement or detachment and thus ensure safety during use and proper functioning.

[0022] How Fig. As shown, in some embodiments a second mounting bracket 14 is attached to the right side of the experimental frame 1, on which the alcohol test module 7 is mounted. This bracket serves to securely fix and hold the alcohol test module 7 in a stable position to prevent displacement or detachment and thus ensure safety during use and proper functioning.

[0023] How Fig. As shown, the alcohol test module 7, in some embodiments, comprises a housing 701 and a blow probe 702. The microcontroller 703 is integrated into the housing 701 and is equipped with a semiconductor-based ethanol sensor 704. The blow probe 702 is attached to the housing 701. When the gas to be detected touches the sensitive layer of the semiconductor-based ethanol sensor 704 (model GMH8563), its electrical conductivity changes. A special circuit is used to assign an output signal strength to this change, corresponding to the concentration of the gas. The microcontroller 703 analyzes and calculates this signal. The feedback is then sent to the open-source mainboard 10 (model MEGA2560).

[0024] How Fig. As shown, in some embodiments the semiconductor-based ethane sensor 704 is arranged in the housing 701, with the breath probe 702 being continuously connected to the housing 701. After the driver enters the vehicle, they must breathe onto the breath probe 702, whereby the sensor detects the alcohol concentration in the breath gas and converts it into an electrical signal that is used for quantitative analysis.

[0025] How Fig.As shown, in some embodiments of the open-source mainboard 10, a buzzer 15 and an expansion interface 16 are provided. The buzzer 15 is an electronic loudspeaker device that generates warning or notification sounds to inform or alert users. The expansion interface 16, on the other hand, serves to extend the interface functionality of the mainboard through external devices, thus solving the problem of insufficient interfaces or limited functionality and improving connectivity flexibility and performance.

[0026] During operation, the brake and accelerator pedals are locked by an electromagnetic locking screw during the vehicle's start-up phase. Once the driver enters the vehicle, they must perform a breathalyzer test using the alcohol test module 7 to measure the alcohol concentration in their breath. If the test result is negative, the vehicle's main control system immediately commands the pedals to be unlocked, allowing the driver to start the vehicle without difficulty. If the test result is positive, the electromagnetic locking switch remains locked, preventing the driver from operating either the brake or accelerator pedal. This physically prevents the vehicle from being started under the influence of alcohol, thus eliminating the risk of accidents caused by drunk driving at its source.As soon as the driver's blood alcohol concentration exceeds the legal limit, the system not only locks the pedals but also immediately activates the vehicle's acoustic and visual warning system. The vehicle's lights flash red, and simultaneously a loud alarm sounds from the buzzer to alert the driver and passengers to the risk of driving under the influence of alcohol. The vehicle is also locked and cannot be started.

[0027] In summary: During vehicle initialization, both the brake and accelerator pedals are locked with an electromagnetic locking mechanism. After the driver enters the vehicle, they must breathe into the breathalyzer module 7 to measure the alcohol concentration in their breath. If no alcohol is detected, the vehicle's main control system immediately releases the pedals, allowing the driver to start the vehicle without any problems. However, if alcohol is detected, the electromagnetic safety switch remains locked to prevent drunk driving from the outset. As soon as the driver has an excessive blood alcohol level, the system not only locks the pedals but also immediately activates the vehicle's audible and visual warning system to alert the driver.

[0028] Finally, it should be noted that the examples described here merely represent preferred embodiments of the present utility model solution and do not limit it. Although the present solution has been explained in detail with reference to the examples mentioned, those skilled in the field may further develop the technical solutions described in these examples or replace individual technical features with equivalent variants. All modifications, equivalent replacements, or improvements made in the spirit and according to the principles of the present utility model solution shall be subject to the scope of protection of this utility model solution. SUMMARY

[0029] The present utility model solution relates to the field of technology for safe driving and specifically to a vehicle system for preventing drunk driving. It comprises a test frame with a brake pedal and accelerator pedal set mounted on its front. Each of these pedal positions is equipped with a brake and accelerator electromagnetic coil assembly. During the vehicle's start-up phase, both the brake and accelerator pedals are locked with an electromagnetic locking element. After the driver enters the vehicle, they must provide a breath sample to the breathalyzer to measure the alcohol concentration in their breath. If no alcohol is detected, the vehicle's main control system immediately issues a command to unlock the pedals, allowing the driver to start the vehicle without difficulty.If alcohol is detected, the electromagnetic locking element remains locked. To prevent driving under the influence at the source, the system not only automatically deactivates the pedals when the blood alcohol concentration is excessive, but also immediately activates the audible and visual warning in the vehicle to warn the driver.
