Abstract
Description
Technical Field
[0001] The present invention generally relates to the technical field of vehicle control, and specifically relates to the configuration and usage method of an anti-cheating alcohol detection system. Background Art
[0002] With the continuous increase in the number of automobiles, traffic safety has become the focus of people's attention. Among them, according to relevant reports, traffic accidents caused by drunk driving account for as high as 50%-60%. How to effectively avoid drunk driving not only depends on self-discipline and legal constraints, but also can rely on instruments to assist drivers in detecting their own blood alcohol concentration. The alcohol detection systems on the market usually rely on alcohol detectors for vehicles. A blowing nozzle is provided on such detectors. When a driver conducts a check operation, they need to blow air into the blowing nozzle first. The gas passes through the blowing nozzle and contacts the alcohol gas sensor inside the detector. The alcohol gas sensor is used to detect the driver's blood alcohol concentration. Moreover, the detector will inform the driver whether the blood alcohol concentration is qualified. Such detectors are also connected to the vehicle ignition system and can directly lock or unlock the ignition system according to the detection result. After a driver gets drunk, they will not be able to start the car, thus avoiding drunk driving at the source.
[0003] However, the above-mentioned alcohol detection system still has the following problems: Judging whether a driver is drunk only through the alcohol gas sensor is relatively one-sided. When there are cheating behaviors such as driver substitution or a driver asking a non-drinking person to blow air for detection, the detector cannot monitor the behavior of the mismatch between the driver and the blowing detection data, and there is still a safety hazard of drunk driving by the driver. Summary of the Invention
[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a configuration and usage method of an anti-cheating alcohol detection system. By setting up a face recognition module, the user's identity is matched before the detection process of the alcohol detection module, and the driver's facial data is continuously recognized during the alcohol detection process, so as to prevent someone other than the user from substituting the user for alcohol detection, the user handing the detector to someone else for alcohol detection after passing the identity recognition, or the driver changing people during the detection process, ensuring that the detection data of the alcohol detection module matches the facial data recognized by the face recognition module, effectively avoiding the occurrence of cheating behaviors, and directly locking or unlocking the vehicle ignition system according to the detection result, thus stopping drunk driving at the source.
[0005] The effects of the present invention are achieved professionally: The present application provides a configuration and usage method of an anti-cheating alcohol detection system, including the following steps: I. Configure the alcohol detection system: S11. Prefabricated detector: A blowing nozzle and an alcohol detection module are provided inside the detector. The alcohol detection module is configured to detect the alcohol concentration of the gas blown into from the blowing nozzle. A face recognition module is also provided inside the detector. The face recognition module is configured to recognize facial data of a person. The face recognition module is located above the blowing nozzle and both are located at the front end of the detector. S12. Prefabricated vehicle control mechanism: The vehicle control mechanism includes an ignition lock. The ignition lock is configured to connect to the detector and the ignition system of the vehicle, and lock or unlock the ignition system of the vehicle according to the detection result of the detector. S13. Pre-stored user data: A storage module for storing user identity information is provided inside the detector. The user identifies facial data through the face recognition module and stores the user identity information in the storage module. II. Usage method: S21. The vehicle is powered on, and the ignition lock locks the ignition system. S22. Confirm user identity: The face recognition module starts to recognize the facial data of the driver and compares it with the user identity information in the storage module. If the data matches, the alcohol detection step is carried out. Otherwise, the ignition lock keeps locking the ignition system of the vehicle. S23. Alcohol detection: The driver blows air into the blowing nozzle. The alcohol detection module detects the alcohol concentration of the gas blown into from the blowing nozzle, and the face recognition module keeps recognizing the facial data of the driver. If the alcohol detection module detects that the alcohol concentration is qualified, and the face recognition module detects that the facial data of the driver has not changed, the ignition lock unlocks the ignition system of the vehicle. Otherwise, the ignition lock keeps locking the ignition system of the vehicle.
[0006] Further, in step S23, the driver needs to blow air into the blowing nozzle at least three times, and each time of blowing needs to last at least three seconds. This not only enables the alcohol detection module to more accurately recognize the alcohol concentration of the blown-in gas, but also makes the detection result of the alcohol concentration more accurate by comparing multiple groups of blowing data, further improving the accuracy of the detection result and effectively avoiding cheating.
[0007] Further, in step S22, when the face recognition module starts to recognize the facial data of the driver, the distance between the driver's face and the detector needs to be kept at 8 - 20 cm. This enables the face recognition module to completely and obliquely recognize the driver's face and ensures the accuracy of face recognition.
[0008] Furthermore, the detector is a hollow housing structure. The hollow part forms an installation cavity, and a circuit board is arranged in the installation cavity. The alcohol detection module and the face recognition module are connected to the circuit board. The detector is provided with a first opening in a hollowed-out manner, and the face recognition module is exposed outside the detector body through the first opening. The circuit board not only supplies power to the alcohol detection module and the face recognition module, but also stores the detection data. By designing the detector as a housing-like structure, it plays a protective role for the circuit board.
[0009] Furthermore, a tubular installation part protrudes from the lower side of the detector. A second opening is formed at the bottom of the installation part, and the alcohol detection module is exposed outside the detector through the second opening; the blowing nozzle is a funnel-shaped structure, so that the narrower end of the blowing nozzle is connected to the alcohol detection module, and the wider end of the blowing nozzle and the installation part are integrated as a whole. This enables the gas exhaled by the driver to better enter the alcohol detection module through the funnel-shaped blowing nozzle, and also enables the blowing nozzle to be detached from the installation part separately for cleaning, and the connection strength between the blowing nozzle and the detector is higher.
[0010] Furthermore, the anti-cheating alcohol detection system further includes an orientation detection module. The orientation detection module includes a sensor assembly arranged on the detector and a receiver arranged on the driver's seat of the vehicle. The receiver is configured to receive the signal emitted by the sensor assembly and measure the distance between the detector and the receiver based on this; with the receiver as the center, the area with a radius of R is the main driving area of the vehicle. In step S22 and step S23, when the orientation detection module detects that the distance between the detector and the receiver is greater than the radius R of the main driving area, the ignition lock keeps the vehicle's ignition system locked. The detector can only perform alcohol detection within the main driving area, ensuring that the person being detected is the driver on the driver's seat, and solving the cheating problem of being detected by users on other seats.
[0011] Furthermore, the usage method of the anti-cheating alcohol detection system further includes the following steps: S24, driving monitoring: After the vehicle is ignited, the face recognition module keeps recognizing the driver on the driver's seat. If the facial data of the driver changes, the ignition lock relocks the vehicle's ignition system. That is, after the driver is changed, alcohol detection needs to be performed again, effectively avoiding the cheating behavior of changing the driver after the vehicle is ignited.
[0012] Further, there may be other connection methods between the face recognition module and the detector. For example, the face recognition module is rotatably connected to the detector. The anti-cheating alcohol detection system further includes an orientation detection module. The orientation detection module includes a sensor assembly disposed on the face recognition module and a receiver disposed on the driver's seat of the vehicle. The orientation detection module detects the orientation of the receiver through the sensor assembly and drives the face recognition module to rotate towards the receiver. The face recognition module can be driven by a motor inside the detector to rotate horizontally around the detector, and the direction of the receiver is detected through the orientation detection module and the face recognition module is driven to rotate towards the receiver. That is, the face recognition module will automatically turn and align with the driver's area, ensuring that the face recognition module can continuously monitor whether there is a change in the driver on the driver's seat.
[0013] Further, the sensor assembly includes a first sensor and a second sensor disposed at the left and right ends of the face recognition module. The distance between the first sensor and the receiver is L1, and the distance between the second sensor and the receiver is L2; when the face recognition module is not facing the receiver, the lengths of L1 and L2 are not equal. At this time, the detector drives the face recognition module to rotate towards the shorter side of L1 and L2 until the lengths of L1 and L2 are equal, that is, the orientation of the face recognition module exactly aligns with the receiver. By using the three-point positioning method, it is only necessary to determine the length difference between L1 and L2 to automatically drive the face recognition module to turn. The positioning operation is simple and has high accuracy.
[0014] Further, an illumination module is also provided on the detector. In steps S22 and S23, the illumination module illuminates the driver's face. By adding a light source, the face recognition module can clearly identify the driver's facial data, making the detection result more accurate.
[0015] Further, a digital display module is also provided on the detector. In steps S22 and S23, the digital display module is configured to display the detection results of the alcohol detection module and the face recognition module. In addition to intuitively showing the driver the specific value of the detected alcohol concentration and whether the detection is qualified, it can also use text to prompt the driver about the operations to be performed and other information, enriching the functions of the detector and effectively improving the interactivity.
[0016] Further, an audio module is also provided on the detector. In steps S22 and S23, the audio module is configured to use voice to prompt the driver about the detection steps and the detection results. By using voice prompts to remind the driver of the detection steps and the detection results, the alcohol detection operation becomes clearer and simpler, further improving the interactivity.
[0017] Furthermore, the storage module can also record and store multiple groups of detection processes and results. The driver can view the past detection records through the storage module, making the functions of the detector more abundant and further enhancing the interactivity.
[0018] Furthermore, the detector and the ignition lock are connected by a transmission line, and the length of the transmission line can be freely stretched and adjusted. By stretching the connection line, the driver can pull the detector to a position close to the face, and when the detection is over, the connection line shortens, occupying less space in the driving area.
[0019] The configuration and usage method of the anti-cheating alcohol detection system provided by this application, by setting up a face recognition module to match the user's identity before the alcohol detection module conducts the detection, thus preventing people other than the user from substituting for the user to conduct the alcohol detection; moreover, the face recognition module is located above the alcohol detection module, so that when the driver blows air, the face recognition module can directly face the center of the driver's face for face recognition, ensuring that the detection data of the alcohol detection module matches the facial data recognized by the face recognition module, and preventing the user from handing the detector to others for alcohol detection after passing the identity recognition; not only that, during the alcohol detection process, the face recognition module continuously recognizes the driver's facial data. Even if the alcohol detection module detects that the alcohol concentration is qualified, as long as the face recognition module detects a change in the driver's facial data, it is determined that the detection is unqualified, effectively preventing someone else from substituting for the driver during the detection process. Thus, the occurrence of cheating behavior is effectively avoided, and drunk driving is stopped at the source. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners
[0022] The present application will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention, rather than limiting the invention. Additionally, it should be noted that for the sake of description, only the parts related to the invention are shown in the drawings.
[0023] Please refer to the attached Figures 1-13 , the embodiment of the present application provides a configuration and usage method of an anti-cheating alcohol detection system, including the following steps: I. Configure the alcohol detection system: S11. Pre-fabricate the detector 1: The detector 1 is provided with a blowing nozzle 110 and an alcohol detection module 210 inside. The alcohol detection module 210 is configured to detect the alcohol concentration of the gas blown in from the blowing nozzle 2. The detector 1 is also provided with a face recognition module 220 inside. The face recognition module 220 is configured to recognize the facial data of the human face. The face recognition module 220 is located above the blowing nozzle 110 and both are located at the front end of the detector 1; S12. Prefabricated vehicle control mechanism: The vehicle control mechanism includes an ignition lock 3, which is configured to connect to the detector 1 and the vehicle's ignition system, and lock or unlock the vehicle's ignition system according to the detection result of the detector 1; S13. Pre-stored user data: A storage module for storing user identity information is provided in the detector 1. The user identifies facial data through the face recognition module 220 and stores the user identity information in the storage module; II. Usage method: S21. The vehicle is powered on, and the ignition lock 3 locks the ignition system; S22. Confirm user identity: The face recognition module 220 starts to identify the driver's facial data and compare it with the user identity information in the storage module. If the data matches, the alcohol detection step is carried out; otherwise, the ignition lock 3 keeps locking the vehicle's ignition system; S23. Alcohol detection: The driver blows air into the blowing nozzle 110, and the alcohol detection module 210 detects the alcohol concentration of the gas blown in from the blowing nozzle 110. The face recognition module 220 keeps identifying the driver's facial data. If the alcohol detection module 210 detects that the alcohol concentration is qualified and the face recognition module 220 detects that the driver's facial data has not changed, the ignition lock 3 unlocks the vehicle's ignition system; otherwise, the ignition lock 3 keeps locking the vehicle's ignition system.
[0024] In this embodiment, by setting the face recognition module 220, the user identity is matched before the detection process of the alcohol detection module 210, thus avoiding someone other than the user substituting for the user to conduct the alcohol detection. Moreover, the face recognition module 220 is located above the alcohol detection module 210, so that when the driver blows air, the face recognition module 220 can directly face the center of the driver's face for face recognition, ensuring that the detection data of the alcohol detection module 220 and the facial data recognized by the face recognition module 220 match, and avoiding the user handing the detector to others for alcohol detection after passing the identity recognition. Not only that, during the alcohol detection process, the face recognition module 220 continuously recognizes the driver's facial data. Even if the alcohol detection module 210 detects that the alcohol concentration is qualified, as long as the face recognition module 220 detects that the driver's facial data has changed, it is determined that the detection is unqualified, effectively avoiding the driver changing people during the detection process. Thus, the occurrence of cheating behaviors is effectively avoided, and drunk driving is stopped at the source.
[0025] In some embodiments of the present application, in step S23, the driver needs to blow air into the blowing nozzle 110 at least three times, and each time of blowing needs to be maintained for at least three seconds.
[0026] In this embodiment, the driver needs to blow at least three times while maintaining facial recognition, and the blowing time is relatively long. This not only enables the alcohol detection module 210 to more accurately identify the alcohol concentration of the blown gas, but also makes the result of alcohol concentration detection more accurate by comparing multiple sets of blowing data. Moreover, the driver always maintains facial recognition during multiple blows, thereby further improving the accuracy of the detection result and effectively avoiding cheating.
[0027] Please refer to the attached Figure 3 , in some embodiments of the present application, in step S22, when the face recognition module 220 starts to recognize the driver's facial data, the distance between the driver's face and the detector 1 needs to be maintained at 8-20 cm. This enables the face recognition module 220 to completely and obliquely recognize the driver's face and ensures the accuracy of face recognition.
[0028] Among them, when the driver's face is too close to or too far from the detector 1, the detector 1 can remind the driver in the form of text or voice.
[0029] Please refer to the attached Figure 4 , in some embodiments of the present application, the detector 1 is a hollow shell structure, and the hollow part forms an installation cavity 101. A circuit board 2 is arranged in the installation cavity 101. The alcohol detection module 210 and the face recognition module 220 are connected to the circuit board 2. The detector 1 is provided with a first opening 102 in a hollowed-out manner, and the face recognition module 220 is exposed outside the detector body 1 through the first opening 102. The circuit board 2 not only supplies power to the alcohol detection module 210 and the face recognition module 220, but also can store detection data. By designing the detector 1 as a shell-like structure, it plays a protective role for the circuit board 2.
[0030] Among them, a detection button 260 is also arranged on the detector 1. The detection button 260 is connected to the circuit board 2. In step S22, when the driver presses the detection button 260, the circuit board 2 receives the signal and controls the face recognition module 220 and the alcohol detection module 210 to start the detection operation.
[0031] Please refer to the attached Figures 4-6, in some embodiments of the present application, a tubular mounting portion 120 protrudes from the lower side of the detector 1. A second opening 121 is provided at the bottom of the mounting portion 120, and the alcohol detection module 210 is exposed outside the detector 1 through the second opening 121; the blowing nozzle 110 has a funnel-shaped structure, so that the narrower end of the blowing nozzle 110 is connected to the alcohol detection module 210, and the wider end of the blowing nozzle 110 and the mounting portion 120 are integrated. This enables the gas exhaled by the driver to better enter the alcohol detection module 210 through the funnel-shaped blowing nozzle 110, and also enables the blowing nozzle 110 to be detached from the mounting portion 120 separately for cleaning, and further improves the connection strength between the blowing nozzle 110 and the detector 1.
[0032] Among them, the detector 1 includes a first housing 1a and a second housing 1b spliced front and back. The first opening 102 and the second opening 121 are both provided on the first housing 1a. The first housing 1a is detachably arranged on the second housing 1b, making the overall assembly and disassembly operation of the detector 1 relatively simple.
[0033] Please refer to the appendix Figures 11-12 , in some embodiments of the present application, the anti-cheating alcohol detection system further includes an orientation detection module. The orientation detection module includes a sensor assembly provided on the detector 1 and a receiver 6 provided on the driver's seat of the vehicle. The receiver 6 is configured to receive the signal emitted by the sensor assembly and measure the distance between the detector 1 and the receiver 6 based on this; with the receiver 6 as the center, the area with a radius of R is the main driving area of the vehicle. In steps S22 and S23, when the orientation detection module detects that the distance between the detector 1 and the receiver 6 is greater than the radius R of the main driving area, the ignition lock 3 keeps the vehicle's ignition system locked.
[0034] In this embodiment, since the detector 1 can be freely moved to any space inside the vehicle, it results in that the user can still use the detector 1 to pass the alcohol detection on the passenger seat or the back seat, and it cannot be guaranteed that the person being detected is the driver on the driver's seat, thus there is a risk of cheating. Therefore, by setting the orientation detection module, as long as the orientation detection module detects that the distance between the detector 1 and the receiver 6 is greater than the radius R of the main driving area, the ignition lock 3 locks the vehicle's ignition system, that is, the detector 1 can only perform alcohol detection within the main driving area, ensuring that the person being detected is the driver on the driver's seat and solving the cheating problem of being detected by users on other seats.
[0035] Please refer to the appendix Figures 9-12 , in some embodiments of the present application, the usage method of the anti-cheating alcohol detection system further includes the following steps: S24. Driving Monitoring: After the vehicle is ignited, the face recognition module 220 continuously identifies the driver in the driver's seat. If the facial data of the driver changes, the ignition lock 3 relocks the vehicle's ignition system.
[0036] In this embodiment, the anti-cheating alcohol detection system unlocks the vehicle ignition system after detecting that the driver's facial data and alcohol concentration are qualified. However, there is a lack of supervision means during the vehicle driving process. After the user passes the alcohol detection and starts the car, the driver can still be replaced, posing a risk of cheating. Therefore, by continuously identifying the driver's facial data through the face recognition module 220 after the vehicle is ignited, the vehicle ignition system is locked as long as the driver's facial data changes. That is, after the driver is replaced, it is necessary to re-perform the alcohol detection, effectively avoiding the cheating behavior of replacing the driver after the vehicle is ignited.
[0037] Please refer to the appendix Figures 9-10 , in some embodiments of the present application, there may be other connection methods between the face recognition module 220 and the detector 1. For example: the face recognition module 220 is rotatably connected to the detector 1. The anti-cheating alcohol detection system further includes an orientation detection module. The orientation detection module includes a sensor assembly disposed on the face recognition module 220 and a receiver 6 disposed on the vehicle's driver's seat. The orientation detection module detects the orientation of the receiver 6 through the sensor assembly and drives the face recognition module 220 to rotate towards the receiver 6.
[0038] In this embodiment, since the viewing angle of the face recognition module 220 is relatively limited, if the detector 1 is placed at a position far from the driver's area, it will be difficult for the face recognition module 220 to monitor the status of the driver in the driver's area, posing a risk of cheating. Therefore, the face recognition module 220 can be driven by a motor in the detector 1 to rotate horizontally around the detector 1, so that the line-of-sight direction of the face recognition module 220 can be adjusted. And the orientation detection module detects the direction of the receiver 6 and drives the face recognition module 220 to rotate towards the receiver 6, that is, the face recognition module 220 will automatically turn and align with the driver's area, ensuring that the face recognition module 220 can continuously monitor whether the driver in the driver's seat has changed.
[0039] Please refer to the appendix Figures 9-12 , in some embodiments of the present application, the sensor assembly includes a first sensor 7a and a second sensor 7b disposed at the left and right ends of the face recognition module 220. The distance between the first sensor 7a and the receiver 6 is L1, and the distance between the second sensor 7b and the receiver 6 is L2; when the face recognition module 220 is not facing the receiver 6, the lengths of L1 and L2 are not equal. At this time, the detector 1 drives the face recognition module 220 to rotate towards the shorter side of L1 and L2 until the lengths of L1 and L2 are equal, that is, the orientation of the face recognition module 220 exactly aligns with the receiver 6.
[0040] In this embodiment, a three-point positioning method is adopted. By respectively arranging a first sensor 7a and a second sensor 7b on the left and right sides of the face recognition module 220, and relying on the difference in the distances between the first sensor 7a, the second sensor 7b and the receiver 6 to determine the line-of-sight direction of the face recognition module 220. A structure similar to a triangle is formed among the first sensor 7a, the second sensor 7b and the receiver 6, and the line-of-sight direction of the face recognition module 220 forms a perpendicular line between the first sensor 7a and the second sensor 7b. When the lengths of L1 and L2 are equal, a structure similar to an isosceles triangle is formed among the first sensor 7a, the second sensor 7b and the receiver 6, so that the line-of-sight direction of the face recognition module 220 can exactly align with the vertex between L1 and L2, that is, the face recognition module 220 can align with the receiver 6, thereby ensuring that the face recognition module 220 can automatically turn and continuously monitor the main driver area. Only by determining the length difference between L1 and L2 can the face recognition module 220 be automatically driven to turn, and the positioning operation is simple and has a high accuracy.
[0041] Please refer to the appendix [[ID=⑥]] Figures 4-5 , in some embodiments of the present application, an illumination module 230 is further arranged on the detector 1. In steps S22 and S23, the illumination module 230 illuminates the face of the driver.
[0042] In this embodiment, the light in the cab is relatively dim, especially at night. The face recognition module 220 will be difficult to recognize the face data of the driver in a dim environment. Therefore, by arranging the lighting unit 230 to increase the light source and illuminate the face of the driver, the face recognition module 220 can clearly recognize the face data of the driver, making the detection result more accurate.
[0043] Among them, preferably, the face recognition module 220 is a binocular camera, which not only has a wider shooting range but also more accurate face recognition. The lighting unit 230 includes lamp beads 231 and a lamp cover 232. The lamp beads 231 are connected to the circuit board 2 and arranged in the middle of the left and right binocular cameras. After the circuit board 2 supplies power to the lamp beads 231, the lamp beads 231 can evenly supplement light for the binocular cameras on both sides. A lamp cover 232 is also covered on the lamp beads 231. The lamp cover 232 is made of a light-transmitting material, and the light emitted by the lamp beads 231 will become more gentle and uniform after passing through the lamp cover 232, avoiding irritating the driver's eyes. A third opening 103 is also hollowed out on the first housing 1a, and the front end of the lamp cover 232 is exposed outside the detector 1 through the third opening 103.
[0044] Please refer to the appendix Figures 4-5, in some embodiments of the present application, a digital display module 240 is further provided on the detector 1. In steps S22 and S23, the digital display module 240 is configured to display the detection results of the alcohol detection module 210 and the face recognition module 220.
[0045] In this embodiment, please refer to the appendix Figure 8 , by providing the digital display module 240, in addition to intuitively showing the driver the specific value of the detected alcohol concentration and whether the detection is qualified, it can also use text to prompt the driver about the operations to be performed and other information. For example, it can indicate whether the driver's current alcohol concentration is "drunk", "drinking", or "normal" through a pointer, display the current time, show whether it is in the "detection" or "setting" interface, and prompt "Please blow three times continuously" when three blows are required for alcohol concentration detection, and so on. Thus, the functions of the detector 1 are enriched, and the interactivity is effectively improved.
[0046] Among them, preferably, the digital display module 240 is a color display screen. The digital display module 240 is powered by the circuit board 2 and receives signals. Not only is the text display clear, but it can also intuitively remind the driver of the detection results or operations through color changes.
[0047] Please refer to the appendix Figures 4-5 , in some embodiments of the present application, an audio module 250 is further provided on the detector 1. In steps S22 and S23, the audio module 250 is configured to use voice prompts to inform the driver of the detection steps and results. By using voice prompts to remind the driver of the detection steps and results, the alcohol detection operation becomes clearer and simpler, further improving the interactivity.
[0048] Among them, preferably, the audio module 250 is a speaker. The audio module 250 is connected to the circuit board 2 and converts the electrical signals of the circuit board 2 into audio signals.
[0049] In some embodiments of the present application, the storage module can also record and store multiple groups of detection processes and results. The driver can view past detection records through the storage module, making the functions of the detector more abundant and further improving the interactivity.
[0050] Among them, a setting button 270 is further provided on the circuit board 2. When the driver presses the setting button 270, the digital display module 240 enters the setting interface, where the driver can not only adjust various parameters of the detector but also view the past detection records stored in the storage module.
[0051] Please refer to the appendix Figure 1 , in some embodiments of the present application, the detector 1 and the ignition lock 3 are connected by a transmission line 4, and the length of the transmission line 4 can be freely adjusted by stretching.
[0052] In this embodiment, after the driver sits on the seat, there is a relatively large distance between his face and the vehicle dashboard. By setting the transmission line 4 to a retractable structure, when the driver pulls the detector 1, with the help of the elongation of the connection line 4, the driver can pull the detector 1 to a position close to the face, and when the detection is over, the connection line 4 shortens, occupying less space in the driving space.
[0053] Preferably, the connection line 4 is a spring wire, so that the connection line 4 can change its length by its own elastic force. This not only has a simple structure, but also when the detector 1 is not in use, the connection line 4 can automatically shorten by the reset elastic force.
[0054] Among them, please refer to the attached Figure 7 , the vehicle control mechanism further includes a support seat 5, the support seat 5 is configured to connect to the vehicle cockpit, a metal sheet 130 is embedded inside the second housing 1b, and a magnet is embedded inside the support seat 5. The magnet adsorbs the metal sheet 130 in the detector 1, so that the detector 1 is detachably connected to the support seat 5 by magnetic adsorption. This not only enables the detector 1 to be adsorbed and fixed in the vehicle cockpit for easy storage, but also makes the operation of taking and placing the detector 1 very simple.
