Description

Technical Field

[0001] This utility model generally relates to the field of vehicle control technology, and specifically to a drunk driving detection device for tracking and identification and an alcohol lock for vehicles. Background Technology

[0002] Traffic accidents caused by drunk driving have become increasingly common in recent years. Reports indicate that drunk driving accounts for 50%-60% of all traffic accidents, making traffic safety a major public concern. To prevent drunk driving, a vehicle-mounted alcohol detector is available on the market. This detector has an air intake; the driver blows air into it, which then comes into contact with an alcohol sensor inside the device. The sensor detects the driver's blood alcohol concentration and informs the driver whether their concentration is within acceptable limits. This detector also connects to the vehicle's ignition system, allowing it to lock or unlock based on the test results. A driver under the influence of alcohol will be unable to start the car, thus preventing drunk driving at its source.

[0003] Furthermore, in addition to detecting the driver's blood alcohol concentration through an alcohol sensor, existing technology also adds a camera to the detector to continuously identify the driver's facial data. When the driver's facial data changes, the detector will relock the vehicle's ignition system, thus preventing cheating behaviors such as changing drivers after passing the alcohol test.

[0004] However, the above-mentioned alcohol detection device has the following problems: Since the camera is fixed to the detection device and the camera's shooting angle is relatively effective, if the driver places the detection device away from the driver's seat after completing the test, the camera will have difficulty detecting the change in the driver's seat, and there is still a risk of cheating. Summary of the Invention

[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a tracking and identification drunk driving detection device and a vehicle alcohol lock. The identification device is driven by a drive mechanism to rotate horizontally around the alcohol detection device, that is, the line of sight of the identification device can be adjusted; and the direction of the receiver is detected by a sensor component and the drive mechanism drives the identification device to rotate toward the receiver, that is, the identification device will automatically turn and align with the driver's seat, ensuring that the identification device can continuously monitor whether the driver in the driver's seat has changed.

[0006] The effect of this utility model is achieved as follows:

[0007] In a first aspect, this application provides a tracking and identification drunk driving detector, including an identification device and an alcohol detection device connected vertically. The identification device is configured to identify the driver's facial data, and the alcohol detection device is configured to detect the driver's blood alcohol concentration. The identification device is rotatably connected to the alcohol detection device via a drive mechanism, so that the identification device can be rotated horizontally relative to the alcohol detection device. The tracking and identification drunk driving detector also includes a position tracking mechanism, which includes a sensor component and a receiver disposed on the identification device. The receiver is configured to be connected to the driver's seat of the vehicle and receive signals sent by the sensor component. After the sensor component detects the position of the receiver, it drives the identification device to rotate toward the position of the receiver via the drive mechanism.

[0008] Furthermore, the sensor assembly includes a right sensor and a left sensor disposed at the left and right ends of the identification device. The distance between the right sensor and the receiver is A1, and the distance between the left sensor and the receiver is A2. When the identification device is not facing the receiver, the lengths A1 and A2 are not equal. At this time, the drive mechanism drives the identification device to rotate towards the shorter side until the lengths of A1 and A2 are equal, that is, the identification device is aligned with the receiver. The identification device can be automatically driven to turn simply by determining the length difference between A1 and A2, making the positioning operation simple and highly accurate.

[0009] Furthermore, both the identification device and the alcohol detection device are hollow shell structures. The identification device houses a first PCB board, and the alcohol detection device houses a second PCB board. The drive mechanism includes a motor and a driven shaft. A driving gear is fixed to the motor shaft, and the driving gear is driven by the motor to rotate horizontally. A driven gear is fixed to the driven shaft, and the driven gear and driving gear mesh with each other, allowing the driven shaft to rotate along with the driving gear, thereby causing the identification device to rotate relative to the alcohol detection device. This gear transmission method for rotating the identification device results in a simple structure and relatively stable transmission.

[0010] Furthermore, the recognition device is positioned above the alcohol detection device. This allows the recognition device to directly center the driver's face when the driver blows into the device, ensuring that the data from the alcohol detection device matches the facial data recognized by the recognition device, effectively preventing cheating.

[0011] Furthermore, the recognition device includes a camera component and an illumination component. The camera component is configured to acquire the driver's facial data, and the illumination component is located near the camera component and configured to illuminate the driver's face to supplement the light intensity. This enables the camera component to clearly recognize the driver's facial data, resulting in more accurate detection results.

[0012] Furthermore, the alcohol detection device has a hollow shell structure. An alcohol gas sensor is installed inside the device, and a conical shroud is installed on the outside. The narrower end of the shroud is connected to the alcohol gas sensor, which is configured to detect the alcohol concentration of the gas blown into the shroud. The detection operation is relatively simple.

[0013] Furthermore, a tubular support protrudes from the lower side of the alcohol detection device, with a through hole at the bottom of the support through which the alcohol gas sensor is exposed to the alcohol detection device; the wider end of the conical cover is connected to the outer end of the support as a single unit. This allows the conical cover to be removed separately from the support for cleaning, and also increases the connection strength between the support and the alcohol detection device.

[0014] Secondly, this application also provides an alcohol lock for a vehicle, including a locking device and a tracking and identification drunk driving detector, wherein the tracking and identification drunk driving detector and the locking device are electrically connected, and the locking device is configured to lock or unlock the vehicle's ignition system.

[0015] The vehicle alcohol lock includes a first detection state and a second detection state. Before vehicle ignition, the vehicle alcohol lock is in the first detection state. The alcohol detection device detects the driver's blood alcohol concentration, and the recognition device maintains the recognition of the driver's blood alcohol concentration. If the alcohol detection device detects a normal blood alcohol concentration and the recognition device detects no change in the driver's facial data, the locking device unlocks the vehicle ignition system; otherwise, the locking device locks the vehicle ignition system. After vehicle ignition, the vehicle alcohol lock is in the second detection state. The recognition device maintains the recognition of the driver's blood alcohol concentration. If the recognition device detects no change in the driver's facial data, the locking device remains unlocked; otherwise, the locking device re-locks the vehicle ignition system. The vehicle alcohol lock directly locks or unlocks the vehicle's ignition system based on the detection results of the alcohol detection device, preventing drunk driving at the source. Furthermore, in addition to the alcohol detection device detecting blood alcohol concentration, the recognition device maintains the recognition of the driver's facial data during alcohol detection and while the vehicle is in motion, effectively preventing cheating behaviors such as changing drivers during the detection process or after passing the test.

[0016] Furthermore, the area with a radius of R centered on the receiver is the driver's area of ​​the vehicle. In the first detection state, when the positioning tracking mechanism detects that the distance between the sensor assembly and the receiver is greater than the radius R of the driver's area, the locking device locks the vehicle's ignition system. The tracking and identification alcohol detection device can only perform alcohol detection within the driver's area, ensuring that the person being tested is the driver in the driver's seat, thus solving the problem of cheating by having users in other seats take the test on their behalf.

[0017] Furthermore, the identification device includes a storage module configured to store the user's facial data. In the first detection state, the identification device first performs identity verification on the driver. If the driver's facial data does not match the user's facial data stored in the storage module, a locking device locks the vehicle's ignition system. This ensures that only certified users can drive the car, thereby preventing unauthorized individuals from taking alcohol tests on behalf of the user and further preventing cheating.

[0018] This application provides a tracking and identification drunk driving detector and a vehicle alcohol lock. The identification device is driven by a drive mechanism to rotate horizontally around the alcohol detection device, meaning the line of sight of the identification device can be adjusted. This allows the identification device to be aligned with and monitor the driver's seat regardless of its location within the vehicle. Furthermore, a sensor assembly detects the direction of the receiver, and the drive mechanism drives the identification device to rotate toward the receiver, automatically turning and aligning the identification device with the driver's seat, ensuring continuous monitoring of any changes in the driver's position.

[0019] Furthermore, a three-point positioning method is employed. Right and left sensors are respectively placed on the left and right sides of the recognition device. The line of sight of the recognition device is determined by the difference in distance between the right and left sensors and the receiver. The right and left sensors and the receiver form a triangle-like structure, and the line of sight of the recognition device is perpendicular to the line between the right and left sensors. When the lengths of the two sensors are equal, the right and left sensors and the receiver form an isosceles triangle-like structure, ensuring that the line of sight of the recognition device is precisely aligned with the vertex between the two sensors. This allows the recognition device to align with the receiver, guaranteeing automatic steering and continuous monitoring of the driver's area. The automatic steering of the recognition device only requires determining the length difference between the two sensors, making the positioning operation simple and highly accurate.

Detailed Implementation

[0030] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0031] Please refer to the attached document. Figure 1-8This application provides a tracking and identification drunk driving detector, including an identification device 1 and an alcohol detection device 2 connected vertically. The identification device 1 is configured to identify the driver's facial data, and the alcohol detection device 2 is configured to detect the driver's blood alcohol concentration. The identification device 1 is rotatably connected to the alcohol detection device 2 via a drive mechanism, so that the identification device 1 can be rotated horizontally relative to the alcohol detection device 2. The tracking and identification drunk driving detector also includes a position tracking mechanism, which includes a sensor assembly and a receiver 3 disposed on the identification device 1. The receiver 3 is configured to be connected to the driver's seat of the vehicle and receive signals sent by the sensor assembly. After the sensor assembly detects the position of the receiver 3, it drives the identification device 1 to rotate toward the position of the receiver 3 via the drive mechanism.

[0032] In this embodiment, the identification device 1 is driven by a drive mechanism to rotate horizontally around the alcohol detection device 2. This means the line of sight of the identification device 1 can be adjusted, allowing it to be aligned with and monitor the driver's seat regardless of the location of the breathalyzer within the vehicle. Furthermore, the sensor assembly detects the direction of the receiver 3, and the drive mechanism drives the identification device 1 to rotate towards the receiver 3. This ensures the identification device 1 automatically turns and aligns with the driver's seat, guaranteeing continuous monitoring of any changes in the driver's position.

[0033] Please refer to the attached document. Figure 2-5 In some embodiments of this application, the sensor assembly includes a right sensor 4a and a left sensor 4b disposed at the left and right ends of the identification device 1. The distance between the right sensor 4a and the receiver 3 is A1, and the distance between the left sensor 4b and the receiver 3 is A2. When the identification device 1 is not facing the receiver 3, the lengths of A1 and A2 are not equal. At this time, the driving mechanism drives the identification device 1 to rotate toward the shorter side of A1 and A2 until the lengths of A1 and A2 are equal, that is, the orientation of the identification device 1 is exactly aligned with the receiver 3.

[0034] In this embodiment, a three-point positioning method is adopted. A right sensor 4a and a left sensor 4b are respectively set on the left and right sides of the recognition device 1. The line of sight of the recognition device 1 is determined by the difference in distance between the right sensor 4a, the left sensor 4b, and the receiver 3. The right sensor 4a, the left sensor 4b, and the receiver 3 form a triangle-like structure, and the line of sight of the recognition device 1 forms a perpendicular line between the right sensor 4a and the left sensor 4b. When the lengths of A1 and A2 are equal, the right sensor 4a, the left sensor 4b, and the receiver 3 form an isosceles triangle-like structure, ensuring that the line of sight of the recognition device 1 is aligned with the vertex between A1 and A2, i.e., the recognition device 1 is aligned with the receiver 3. This ensures that the recognition device 1 can automatically turn and continuously monitor the driver's area. Only the length difference between A1 and A2 needs to be determined to automatically drive the recognition device 1 to turn, making the positioning operation simple and highly accurate.

[0035] Please refer to the attached document. Figure 7 In some embodiments of this application, both the identification device 1 and the alcohol detection device 2 are hollow shell structures. The identification device 1 has a first PCB board 110 inside, and the alcohol detection device 2 has a second PCB board 210 inside. The driving mechanism includes a motor 211 and a driven shaft 111. A drive gear 212 is fixed on the shaft of the motor 211, and the drive gear 212 is driven by the motor 211 to rotate horizontally. The driven gear 112 is fixed on the driven shaft 111, and the driven gear 112 meshes with the drive gear 212, allowing the driven shaft 111 to rotate together with the drive gear 212, thereby causing the identification device 1 to rotate relative to the alcohol detection device 2. Driving the identification device 1 to rotate via gear transmission results in a simple structure and relatively stable transmission.

[0036] The identification device 1 includes a first housing 1a and a second housing 1b joined together, while the alcohol detection device 2 includes a third housing 2a and a fourth housing 2b joined together, making the tracking and identification drunk driving detection device easy to disassemble and assemble. Furthermore, when the identification device 1 is not rotating, the first housing 1a and the third housing 2a are connected as a single unit, and the second housing 1b and the fourth housing 2b are connected as a single unit, making the tracking and identification drunk driving detection device more visually integrated. The internal components of the identification device 1 and the alcohol detection device 2 are also less likely to be exposed, and manufacturing is more convenient.

[0037] Please refer to the attached document. Figure 2-3 In some embodiments of this application, the identification device 1 is located above the alcohol detection device 2.

[0038] In this embodiment, if the identification device 1 and the alcohol detection device 2 are set up separately, when the driver uses the identification device 1 to identify facial data, other people with normal alcohol content can also be allowed to take the alcohol test, posing a risk of cheating. Therefore, by placing the identification device 1 above the alcohol detection device 2, when the driver blows into the alcohol detection device 2, the identification device 1 can directly identify the center of the driver's face, ensuring that the detection data of the alcohol detection device 2 matches the facial data identified by the identification device 1, effectively preventing cheating.

[0039] Please refer to the attached document. Figure 2-3 In some embodiments of this application, the identification device 1 includes a camera component 120 and an illumination component 130. The camera component 120 is configured to collect facial data of the driver, and the illumination component 130 is disposed near the camera component 120 and configured to illuminate the driver's face to supplement the light intensity.

[0040] In this embodiment, the lighting inside the driver's cab is dim, especially at night, making it difficult for the camera assembly 120 to capture the driver's facial data in such a dark environment. Therefore, by setting up the lighting assembly 130, an additional light source is provided to illuminate the driver's face, enabling the camera assembly 120 to clearly identify the driver's facial data and making the detection results more accurate.

[0041] Preferably, please refer to the appendix. Figure 8 The camera assembly 120 is a binocular camera, offering a wider shooting angle and clearer facial recognition. Two symmetrical binocular cameras are connected to the first PCB board 110 and exposed in the recognition device 1. The lighting assembly 130 includes LED beads 131 and a lampshade 132. LED beads 131 are connected to the first PCB board 110 and positioned between the two binocular cameras. After the first PCB board 110 supplies power to the LED beads 131, the LED beads 131 can evenly supplement the light to the two binocular cameras. The lampshade 132, made of a light-transmitting material, covers the LED beads 131, making the light emitted by the LED beads 131 more gentle and uniform, thus avoiding eye strain for the driver.

[0042] Please refer to the attached document. Figure 6 In some embodiments of this application, the alcohol detection device 2 is a hollow shell structure. An alcohol gas sensor 220 is provided inside the alcohol detection device 2, and a conical cover 230 is provided on the outside of the alcohol detection device 2. The narrower end of the conical cover 230 is connected to the alcohol gas sensor 220. The alcohol gas sensor 220 is configured to detect the alcohol concentration of the gas blown in from the conical cover 230.

[0043] In this embodiment, the alcohol gas sensor 220 and the second PCB board 210 inside the alcohol detection device 2 are electrically connected. When the driver performs an alcohol detection operation, he blows air into the conical cover 230. The blown air passes through the conical cover 230 and contacts the alcohol gas sensor 220. The alcohol gas sensor 220 then detects the alcohol concentration and sends an electrical signal to the second PCB board 210 based on the detection result. The detection operation is relatively simple.

[0044] The alcohol detection device 2 is also equipped with a display screen 250 and a speaker 260. The display screen 250 and the speaker 260 are connected to the second PCB board 210. When the second PCB board 210 receives a signal from the alcohol gas sensor 220, the second PCB board 210 converts the electrical signal into an image signal and an audio signal, and transmits them to the display screen 250 and the speaker 260 respectively. The driver is then reminded of the test results through digital display and voice broadcast. Of course, the display screen 250 and the speaker 260 can also be used to remind the driver of operating procedures and other information, which enhances human-computer interaction and has strong practicality.

[0045] Please refer to the attached document. Figure 6 In some embodiments of this application, a tubular support portion 240 protrudes from the lower side of the alcohol detection device 2. A through hole 241 is provided at the bottom of the support portion 240, through which the alcohol gas sensor 220 is exposed to the alcohol detection device 2. The wider end of the conical cover 230 is integrated with the outer end of the support portion 240. This allows the conical cover 230 to be detached from the support portion 240 for cleaning and also increases the connection strength between the support portion 240 and the alcohol detection device 2.

[0046] Please refer to the attached document. Figure 1 This application embodiment also provides a vehicle alcohol lock, including a locking device 5 and a tracking and identification drunk driving detector. The tracking and identification drunk driving detector and the locking device 5 are electrically connected. The locking device 5 is configured to lock or unlock the vehicle's ignition system.

[0047] The vehicle alcohol lock includes a first detection state and a second detection state. Before the vehicle is started, the vehicle alcohol lock is in the first detection state. The alcohol detection device 2 detects the driver's alcohol concentration, and the recognition device 1 maintains the recognition of the driver's alcohol concentration. If the alcohol detection device 2 detects that the alcohol concentration is qualified and the recognition device 1 detects that the driver's facial data has not changed, the locking device 5 unlocks the vehicle ignition system. Otherwise, the locking device 5 locks the vehicle ignition system. After the vehicle is started, the vehicle alcohol lock is in the second detection state. The recognition device 1 maintains the recognition of the driver's alcohol concentration. If the recognition device 1 detects that the driver's facial data has not changed, the locking device 5 remains unlocked. Otherwise, the locking device 5 relocks the vehicle ignition system.

[0048] In this embodiment, the vehicle's alcohol lock directly locks or unlocks the vehicle's ignition system via locking device 5 based on the detection result of the alcohol detection device. This prevents the vehicle from starting when the test fails, thus avoiding drunk driving at its source. Furthermore, in addition to the alcohol detection device 2 detecting alcohol concentration, the recognition device 1 continuously recognizes the driver's facial data during the alcohol test and while the vehicle is in motion, monitoring for any changes in the driver's identity. This effectively prevents cheating behaviors such as changing drivers during the test or after the test has passed.

[0049] Preferably, the drunk driving detection device and the locking device 5 are connected by a spring wire 6. The spring wire 6 can extend and deform, allowing the user to extend the drunk driving detection device a greater distance. After use, the cable can be automatically retracted by the restoring force of the spring wire 6, making it more convenient to use.

[0050] Please refer to the appendix. Figure 7 The vehicle alcohol lock also includes a base 7, which is configured to connect to the vehicle's driver's cabin. A metal plate 270 is embedded in the inner side of the tracking and identification drunk driving detector, and a magnet is embedded inside the base 7, so that the tracking and identification drunk driving detector can be detachably connected to the base 7 by magnetic attraction. This not only allows the tracking and identification drunk driving detector to be attached and fixed in the vehicle's cabin for easy storage, but also makes the operation of taking out and placing the tracking and identification drunk driving detector very simple.

[0051] Please refer to the attached document. Figure 4-5 In some embodiments of this application, the area with a radius of R centered on the receiver 3 is the main driving area of ​​the vehicle. In the first detection state, when the orientation tracking mechanism detects that the distance between the sensor assembly and the receiver 3 is greater than the radius R of the main driving area, the locking device 5 locks the vehicle's ignition system.

[0052] In this embodiment, users can still use the tracking and identification drunk driving detector to pass an alcohol test while in the front passenger seat or rear seat. However, this does not guarantee that the person being tested is the driver in the main driver's seat, posing a risk of cheating. Therefore, by using a position tracking mechanism to detect whether the distance between the sensor assembly and receiver 3 is greater than the radius R of the driver's driving area, the locking device 5 locks the vehicle's ignition system when the tracking and identification drunk driving detector goes beyond the driver's driving area. This ensures that the tracking and identification drunk driving detector can only perform alcohol tests within the driver's driving area, guaranteeing that the person being tested is the driver in the main driver's seat and solving the problem of cheating by having users in other seats take the test on behalf of the driver.

[0053] In some embodiments of this application, the identification device 1 includes a storage module configured to store the user's facial data; in the first detection state, the identification device 1 first performs identity recognition on the driver; if the driver's facial data does not match the user's facial data in the storage module, the locking device 5 locks the vehicle's ignition system.

[0054] In this embodiment, by setting up a storage module, the identification device 1 matches the user's identity before the alcohol test, so that only the certified user can drive the car, thereby preventing people other than the user from taking the alcohol test on their behalf and further preventing cheating.
