Description

Technical Field

[0001] The present invention relates to the technical field of vehicle drunk driving detection, and in particular to the configuration of a drunk driving intelligent detection system and a detection method. Background Art

[0002] In recent years, traffic accidents caused by drunk driving are common. How to effectively avoid it depends not only on self-restraint and legal constraints, but also on adding a device to detect the alcohol content in the driver's body to fundamentally eliminate the risk of drunk driving. Currently, the alcohol detection instruments on the market are implemented in the form of electronically controlled alcohol locks.

[0003] For example, an existing patent provides an intelligent drunk driving detection system, method and vehicle (application number: CN202411308353.8), which embeds a camera and an alcohol tester in the middle of the vehicle's steering wheel and connects it to a controller to obtain the driver's facial information and the driver's breath alcohol data, thereby facilitating confirmation of whether the driver is drunk driving. A gear switch is set on the car's gear shift device, and the controller controls the gear switch to control the gear shift device through the detected data, thereby directly controlling the vehicle's driving state. As a result, the intelligent drunk driving detection system avoids the occurrence of drunk driving from the source of the vehicle.

[0004] However, the above scheme has the following problems: 1. The camera and alcohol tester are set in the center of the steering wheel. When a car accident occurs, it will affect the popping out of the airbag on the steering wheel, posing a safety hazard; 2. Detecting whether the user is driving under the influence of alcohol requires responses from multiple devices such as cameras and alcohol testers. The detection process is relatively complicated, and once one of the devices fails, it will affect the judgment result of the entire detection system, causing greater safety hazards; 3. The detection system will only start to operate when the car is ignited. Not only does it increase unnecessary fuel consumption during the detection process, but if the test fails, the user needs to turn off the engine again, making the vehicle control operation more troublesome. Summary of the invention

[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a configuration and detection method of an intelligent drunk driving detection system, in which the installation position of the detector will not affect the popping out of the airbag in the car, thereby avoiding safety hazards; and, after the alcohol detection unit detects the alcohol coefficient, it directly drives the cabin door to cover or avoid the ignition cabin, that is, directly locks or unlocks the vehicle's ignition system, which not only makes the detection and vehicle control operations of the detection system relatively simple, but also completes the detection process before the vehicle is ignited, reducing the fuel consumption of the car; not only that, by arranging a pressure sensor on the car seat to detect whether the user is seated and directly control the detector to be turned on or off, the user needs to re-test the alcohol coefficient every time he leaves the car seat, making the detection system more intelligent, and when one of the pressure sensor and the alcohol detection unit fails, the cabin door cannot be opened, thereby avoiding equipment failure affecting the detection results of the detection system and improving safety.

[0006] The effect of the present invention is achieved in this way: This application provides a configuration and detection method of a drunk driving intelligent detection system, including: 1.Configure the detection system: S11, a prefabricated detector, wherein an ignition chamber is recessed on the detector, a chamber door is movably connected to the ignition chamber, an air blowing nozzle and an alcohol detection unit are also provided in the detector, the alcohol detection unit is configured to detect the alcohol concentration of the gas blown into the air blowing nozzle, and drive the chamber door to cover or avoid the ignition chamber through a driving mechanism; S12, installing the detector, installing the detector in the cab of the car, and making the ignition switch of the car located in the ignition compartment; S13, installing a sensing system, setting a pressure sensor on the car seat, the pressure sensor being electrically connected to the detector, the pressure sensor being configured to convert a pressure signal into an electrical signal for regulating the detector to be turned on or off; 2. Detection method: S21, the user sits on the car seat, the pressure sensor senses the pressure signal and transmits an electrical signal to the detector, and the detector turns on; S22, the user blows toward the blowing nozzle on the detector, and the alcohol detection unit detects the alcohol coefficient of the gas introduced from the blowing nozzle; S23a, the alcohol detection unit detects that the alcohol coefficient is qualified, and drives the door to avoid the ignition compartment through the driving mechanism, the ignition switch is exposed, and the user can press the ignition switch to start the car; S23b, the alcohol detection unit detects that the alcohol coefficient exceeds the standard, and drives the door to cover the ignition compartment through the driving mechanism, so that the ignition switch is covered in the detector and the user cannot start the car; S24, the user stands up from the car seat, the detector receives the electrical signal from the pressure sensor, the driving mechanism drives the door to cover the ignition chamber, and the detector is turned off.

[0007] Furthermore, the driving mechanism includes a servo motor and a rack. The servo motor is sleeved with a gear, the rack is meshed with the gear, and one end of the rack is connected to the door. The servo motor is configured to drive the gear to rotate, and the rack is driven to slide in the horizontal direction, thereby driving the door to move together. Through the cooperation of the gear and the rack, the rotation of the servo motor is converted into the horizontal movement of the door, which not only stabilizes the transmission process, but also makes the opening or closing operation of the door easier.

[0008] Furthermore, a limit cavity extending in the left and right directions is formed in the detector, the limit cavity is connected to the ignition chamber, the chamber door is connected to the detector through the limit cavity and can slide left and right along the limit cavity, so that the chamber door and the detector remain relatively fixed in the vertical direction and the front and back direction. The connection strength between the chamber door and the detector is improved, making the opening and closing operation of the chamber door more stable.

[0009] Furthermore, the blowing nozzle and the alcohol detection unit are connected by a connecting tube, and the connecting tube includes a telescopic section, and the telescopic section can be telescopically adjusted in length, so that the blowing nozzle can be movably arranged on the detector. The user can pull the blowing nozzle to a position close to the mouth, which is convenient for the user to blow, making the alcohol detection operation easier.

[0010] Furthermore, an elastic reset mechanism is provided between the connecting tube and the detector. When the blowing nozzle is pulled out in a direction away from the detector, the elastic reset mechanism applies a reset elastic force to the connecting tube, so that the blowing nozzle always has a tendency to retract toward the detector. After the user uses the blowing nozzle each time, the blowing nozzle will automatically retract to a position close to the detector under the traction of the elastic reset mechanism, making the operation more convenient.

[0011] Furthermore, the elastic reset mechanism includes a fixed part fixedly connected to the detector and a rotating part rotatably connected to the fixed part, and an elastic part is arranged between the fixed part and the rotating part; the connecting tube is connected to the rotating part, and when the telescopic section is extended, the connecting tube is extended and drives the rotating part to rotate, the elastic part is deformed and applies a reset elastic force to the rotating part, the rotating part has a tendency to rotate back and drives the connecting tube to retract. When the connecting tube is driven to extend and retract by the blowing nozzle, the rotating part is pulled to rotate relative to the fixed part, the transmission process is simple and relatively stable, and the elastic deformation of the elastic part pulls the connecting tube to reset, and the operation is relatively simple.

[0012] Furthermore, the fixed part and the rotating part are connected front to back, the rotating part protrudes toward the fixed part to form a connecting part, one end of the fixed part close to the rotating part is recessed to form a connecting groove, and the connecting part extends into the connecting groove; the elastic part is a clockwork spring, one end of the elastic part is fixed to the connecting part, and the other end is fixed to the groove wall of the connecting groove. When the rotating part drives the connecting part to rotate, the connecting part applies a torsional force to the elastic part, and the elastic part produces a bending elastic deformation and applies a reverse torsional force to the connecting part. This makes the connection strength between the rotating part and the fixed part higher, and the rotation process of the rotating part more stable. In addition, the elastic part adopts a clockwork spring, which not only has good strength and stability, but also can apply a large torque to the connecting part, making the rotation of the connecting part more stable.

[0013] Furthermore, a bracket is also provided in the detector, and the bracket is threadedly wrapped around the rotating member, and the bracket is configured to support the connecting tube, and when the blowing nozzle is pulled, the connecting tube moves along the bracket around the rotating member, making the extension and retraction process of the connecting tube more stable, and making the connecting tube wrap around the rotating member, not only the connecting tube can be set to a longer length, that is, the user can stretch the blowing nozzle for a longer distance, but also the connecting tube can better drive the rotating member to rotate when it is extended and retracted, thereby making the extension and adjustment operation of the blowing nozzle more stable and smooth.

[0014] Furthermore, a limiting groove is provided on the upper edge of the side wall of the rotating member in the front-to-back direction, a connecting member is provided on the connecting tube, and a limiting protrusion is provided on the side of the connecting member close to the rotating member, and the limiting protrusion is clamped on the rotating member through the limiting groove; when the connecting tube moves around the rotating member, the limiting protrusion slides forward and backward along the limiting groove. Not only does it strengthen the connection strength between the two, so that the connecting tube can drive the rotating member to rotate, but also when the connecting tube is extended along the bracket, the limiting protrusion slides along the limiting groove, making the transmission process between the connecting tube and the rotating member more stable and smooth, and more stable.

[0015] Furthermore, the detector is also provided with a display unit, and in step S23a and step S23b, the display unit is configured to output the alcohol coefficient detected by the alcohol detection unit, so that the user can intuitively understand his own alcohol concentration during the detection process, expanding the function of the drunk driving intelligent detection system and making it more practical.

[0016] The configuration and detection method of a drunk driving intelligent detection system provided by the present application, by installing the detector in the car cab and setting the ignition switch of the car ignition system in the ignition chamber of the detector, the detector will not affect the popping out of the airbag in the car, avoiding safety hazards; and, after the user blows into the air blowing nozzle, the alcohol detection unit detects the alcohol coefficient and directly drives the chamber door to cover or avoid the ignition chamber, that is, directly locks or unlocks the vehicle's ignition system, which not only makes the detection of the detection system and the vehicle control operation relatively simple, but also completes the detection process before the vehicle is ignited, reducing the fuel consumption of the car; not only that, by arranging a pressure sensor on the car seat, the pressure sensor detects whether the user is sitting or not and directly controls the detector to be turned on or off, so that the user needs to re-detect the alcohol coefficient every time he leaves the car seat, making the detection system more intelligent, and when one of the pressure sensor and the alcohol detection unit fails, the chamber door cannot be opened, and the user cannot ignite the car, thereby avoiding affecting the detection result of the detection system and improving safety.

Detection method: S21, the user sits on the car seat 8, the pressure sensor senses the pressure signal and transmits an electrical signal to the detector 1, and the detector 1 is turned on; S22, the user blows toward the blowing nozzle 2 on the detector 1, and the alcohol detection unit 3 detects the alcohol coefficient of the gas transmitted from the blowing nozzle 2; S23a, the alcohol detection unit 3 detects that the alcohol coefficient is qualified, and drives the door 110 to avoid the ignition compartment 101 through the driving mechanism, so that the ignition switch 7 is exposed, and the user can press the ignition switch 7 to start the car; S23b, the alcohol detection unit 3 detects that the alcohol coefficient exceeds the standard, and drives the door 110 to cover the ignition compartment 101 through the driving mechanism, so that the ignition switch 7 is covered in the detector 1, and the user cannot start the car; S24, the user stands up from the car seat 8, the detector 1 receives the electrical signal from the pressure sensor, the driving mechanism drives the door 110 to cover the ignition chamber 101, and the detector 1 is closed.

[0021] In this embodiment, by installing the detector 1 in the car cab and setting the ignition switch 7 of the car ignition system in the ignition chamber 101 of the detector 1, the detector 1 will not affect the ejection of the airbag in the car, avoiding safety hazards; and, after the user blows air into the blowing nozzle 2, the alcohol detection unit 3 detects the alcohol coefficient and directly drives the chamber door 110 to cover or avoid the ignition chamber 101, that is, directly locks or unlocks the vehicle's ignition system, which not only makes the detection of the detection system and the vehicle control operation relatively simple, but also completes the detection process before the vehicle is ignited, reducing the fuel consumption of the car; not only that, by setting a pressure sensor on the car seat 8, the pressure sensor detects whether the user is sitting or not and directly controls the detector 1 to be turned on or off, so that the user needs to re-detect the alcohol coefficient every time he leaves the car seat 8, making the detection system more intelligent, and when one of the pressure sensor and the alcohol detection unit 3 fails, the chamber door 110 cannot be opened, and the user cannot ignite the car, thereby avoiding affecting the detection result of the detection system and having better safety.

[0022] Please refer to the attached Figure 5-6 In some embodiments of the present application, the driving mechanism includes a servo motor 4 and a rack 410, a gear 420 is sleeved on the servo motor 4, the rack 410 is meshed with the gear 420, and one end of the rack 410 is connected to the warehouse door 110; the servo motor 4 is configured to drive the gear 420 to rotate, and the rack 410 is driven to slide in the horizontal direction, thereby driving the warehouse door 110 to move together.

[0023] In this embodiment, the rotation of the servo motor 4 is converted into the horizontal movement of the door 110 through the cooperation of the gear 420 and the rack 410, which not only stabilizes the transmission process but also makes the opening or closing operation of the door 110 easier.

[0024] Among them, the alcohol detection unit 3 is connected to a PCB board 301, and the servo motor 4 is electrically connected to the PCB board 301. After the alcohol detection unit 3 detects the alcohol coefficient, it transmits an electrical signal to the PCB board 301, and the PCB board 301 transmits an electrical signal to the servo motor to control the servo motor 4 to rotate forward or reverse, which is transmitted through the gear 420 and the rack 410 to control the compartment door 110 to cover or avoid the ignition compartment 101.

[0025] Please refer to the attached Figure 4 In some embodiments of the present application, a limit cavity 101 extending in the left and right directions is formed in the detector 1, the limit cavity 102 is connected to the ignition chamber 101, and the chamber door 110 is connected to the detector 1 through the limit cavity 102 and can slide left and right along the limit cavity 102, so that the chamber door 110 and the detector 1 remain relatively fixed in the vertical direction and the front-back direction. The connection strength between the chamber door 110 and the detector 1 is improved, and the chamber door 110 is prevented from being offset during the movement, causing the ignition chamber 101 to be exposed, thereby causing the user to still press the ignition switch 7 when the alcohol coefficient is unqualified, making the opening and closing operations of the chamber door 110 more stable.

[0026] The detector 1 is a split structure, including an upper shell 1a and a lower shell 1b that are assembled front and back. A notch is formed at the lower left corner of the upper shell 1a. The notch and the lower shell 1b are assembled to form an ignition chamber 101. The bottom end of the upper shell 1a forms a limited position cavity 102. The lower shell 1b is recessed with a positioning groove 103 extending in the left and right directions at the part close to the ignition chamber 101. The rack 410 is arranged in the positioning groove 103, so that the rack 410 is constrained by the positioning groove 103 and can only slide in the left and right directions, thereby further limiting the movement of the door 110 at the end of the rack 410, and further improving the stability of the opening and closing operation of the door 110.

[0027] Please refer to the attached Figure 6 and attached Fig. 9 In some embodiments of the present application, the air blowing nozzle 2 and the alcohol detection unit 3 are connected by a connecting tube 5, and the connecting tube 5 includes a telescopic section 510, and the telescopic section 510 can be telescopically adjusted in length, so that the air blowing nozzle 2 can be movably arranged on the detector 1.

[0028] In this embodiment, when the user sits on the car seat 8, there will be a large distance between the user's head and the detector 1, and it is troublesome to directly put the mouth close to the air blowing nozzle 2 to blow. Therefore, by providing a connecting tube 5 between the air blowing nozzle 2 and the alcohol detection unit 3, the telescopic section 510 of the connecting tube 5 is telescopically arranged, so that when the user sits, the air blowing nozzle 2 can be directly pulled, and the air blowing nozzle 2 drives the telescopic section 510 to stretch, so that the user can pull the air blowing nozzle 2 to a position close to the mouth, which is convenient for the user to blow, making the alcohol detection operation easier.

[0029] Among them, the upper shell 1a is hollowed out to form a through hole 104, and the connecting tube 5 also includes a connecting section 520. One end of the telescopic section 510 is connected to the alcohol detection unit 3, and the other end is connected to the connecting section 520. The outer end of the connecting section 520 is exposed to the detector 1 through the through hole 104 and connected to the air blowing nozzle 2. The connecting section 520 is a hose with a fixed length. When the user pulls the air blowing nozzle 2, the connecting section 520 is pulled out together and the telescopic section 510 is stretched.

[0030] Please refer to the attached Figure 7-9 In some embodiments of the present application, an elastic reset mechanism is provided between the connecting tube 5 and the detector 1. When the air blowing nozzle 2 is pulled out in a direction away from the detector 1, the elastic reset mechanism applies a reset elastic force to the connecting tube 5, so that the air blowing nozzle 2 always has a tendency to retract toward the detector 1.

[0031] In this embodiment, an elastic reset mechanism is provided between the connecting tube 5 and the detector 1, so that the user does not need to manually reset the blowing nozzle 2 after each use. The user only needs to loosen the blowing nozzle 2, and the blowing nozzle 2 will automatically retract to a position close to the detector 1 under the traction of the elastic reset mechanism, which makes the operation more convenient.

[0032] Please refer to the attached Figure 8 In some embodiments of the present application, the elastic reset mechanism includes a fixed part 610 fixedly connected to the detector 1 and a rotating part 620 rotatably connected to the fixed part 610, and an elastic part 611 is arranged between the fixed part 610 and the rotating part 620; the connecting tube 5 is connected to the rotating part 620, when the telescopic section 510 is extended, the connecting tube 5 is extended and drives the rotating part 620 to rotate, the elastic part 611 is deformed and applies a reset elastic force to the rotating part 620, and the rotating part 620 has a tendency to rotate back and drives the connecting tube 5 to retract.

[0033] In this embodiment, a rotatable rotating member 620 is provided, and when the connecting tube 5 is driven to extend and retract by the blowing nozzle 2, the rotating member 620 is driven to rotate relative to the fixed member 610, and the transmission process is simple and relatively stable. In addition, an elastic member 611 is provided between the fixed member 610 and the rotating member 620, and the connecting tube 5 is pulled to reset through the elastic deformation of the elastic member 611, and the operation is relatively simple.

[0034] Please refer to the attached Figure 8In some embodiments of the present application, the fixed member 610 and the rotating member 620 are connected front to back, the rotating member 620 protrudes toward the fixed member 610 to form a connecting portion 621, and one end of the fixed member 610 close to the rotating member 620 is recessed to form a connecting groove 612, and the connecting portion 621 extends into the connecting groove 612; the elastic member 611 is a clockwork spring, one end of the elastic member 611 is fixed to the connecting portion 621, and the other end is fixed to the groove wall of the connecting groove 612. When the rotating member 620 drives the connecting portion 621 to rotate, the connecting portion 621 applies a torsional force to the elastic member 611, and the elastic member 611 produces a bending elastic deformation and applies a reverse torsional force to the connecting portion 621.

[0035] In this embodiment, the protruding connecting portion 621 on the rotating member 620 and the connecting groove 612 at the bottom of the fixing member 610 are rotated together, so that the connection strength between the rotating member 620 and the fixing member 610 is higher, and the rotation process of the rotating member 620 is more stable. In addition, the elastic member 611 adopts a spring, which not only has good strength and stability, but also has good Fig. 9 As shown, when the connecting tube 5 is driven to stretch, the rotating part 620 drives the connecting part 621 to rotate, and the spring rolls inward as the connecting part 621 rotates and can apply a larger torque to the connecting part 621, thereby making the rotation of the connecting part 621 more stable.

[0036] Among them, a plurality of first positioning protrusions 613 protrude from the top upper edge of the fixing member 610, and a plurality of second positioning protrusions 105 correspondingly protrude from the bottom end of the upper shell 1a. Any first positioning protrusion 613 is inserted between two adjacent second positioning protrusions 105, so that the fixing member 610 and the upper shell 1a remain relatively fixed, that is, the fixing member 610 and the detector 1 remain relatively fixed.

[0037] Of course, in other embodiments of the present application, the elastic member 611 may also be a spring, a spring sheet, etc.

[0038] Please refer to the attached Figure 7 In some embodiments of the present application, a bracket 630 is further provided in the detector 1. The bracket 630 is threadedly wrapped around the rotating member 620. The bracket 630 is configured to support the connecting tube 5. When the blowing nozzle 2 is pulled, the connecting tube 5 moves along the bracket 630 around the rotating member 620.

[0039] In this embodiment, a bracket 630 is provided to support the connecting tube 5, so that the extension and retraction process of the connecting tube 5 is more stable, and the bracket 630 is threadedly wrapped around the rotating member 620, so that the connecting tube 5 also wraps around the rotating member 620, which not only allows the connecting tube 5 to be set to a longer length, that is, the user can stretch the blowing nozzle 2 a longer distance, but also allows the connecting tube 5 to move around the rotating member 620 when extending and retracting, thereby better driving the rotating member 620 to rotate, and further making the stretching and adjustment operation of the blowing nozzle 2 more stable and smooth.

[0040] The upper end of the bracket 630 is further recessed to form an arc-shaped bracket 631, and the connecting pipe 5 is placed in the bracket 631, so that the connecting pipe 5 is constrained by the bracket 631 and is not easy to separate from the bracket 630, and has better stability.

[0041] Please refer to the attached Figure 8 In some embodiments of the present application, a limiting groove 622 is provided on the upper edge of the side wall of the rotating member 620 in the front-to-back direction, a connecting member 530 is provided on the connecting tube 5, and a limiting protrusion 531 is provided on the side of the connecting member 530 close to the rotating member 620, and the limiting protrusion 531 is clamped to the rotating member 620 through the limiting groove 622; when the connecting tube 5 moves around the rotating member 620, the limiting protrusion 531 slides back and forth along the limiting groove 622.

[0042] In this embodiment, when the rotating member 620 moves around the rotating member 620, its vertical position relative to the rotating member 620 also changes. Therefore, by providing the mutually engaged limiting protrusion 531 and the limiting groove 622 between the rotating member 620 and the connecting tube 5, not only the connection strength between the two is strengthened, so that the connecting tube 5 can drive the rotating member 620 to rotate, but also when the connecting tube 5 is extended along the bracket 620, the limiting protrusion 531 slides upward along the limiting groove 622, and vice versa when the connecting tube 5 is contracted along the bracket 620, the limiting protrusion 631 slides downward along the limiting groove 622, so that the transmission process between the connecting tube 5 and the rotating member 620 is more stable and smooth, and the stability is better.

[0043] The connecting pipe 5 further includes a sleeve-shaped connector 540, which is disposed between the telescopic section 510 and the connecting section 520. One end of the connector 540 is plugged into the telescopic section 510, and the other end is plugged into the telescopic section 510, thereby connecting the telescopic section 510 and the connecting section 520 as a whole. The connecting member 530 is a Z-shaped structure as a whole, and the portion of the upper side of the connecting member 530 extending in the horizontal direction is fixed to the connector 540 by screw connection, and the limiting protrusion 531 on the lower side of the connecting member 530 is inserted into the limiting groove 622 of the rotating member 620, which is convenient for installation and disassembly.

[0044] Please refer to the attached Figure 1In some embodiments of the present application, the detector 1 is further provided with a display unit 120. In step S23a and step S23b, the display unit 120 is configured to output the alcohol coefficient detected by the alcohol detection unit 3. This allows the user to intuitively understand his or her own alcohol concentration during the detection process, thereby expanding the function of the drunk driving intelligent detection system and improving practicality.
