Description

Technical Field

[0001] This utility model relates to the field of drunk driving detection technology, and more specifically, to a protective laser drunk driving detection device. Background Technology

[0002] While traditional alcohol testing methods are widely used, they have limitations in terms of accuracy, portability, and speed of response. These traditional methods typically rely on chemical reactions or electrochemical sensors, which can lead to errors due to environmental factors or equipment aging. Laser detection equipment makes breathalyzer testing more efficient and accurate. The detection device emits a laser beam of a specific wavelength and analyzes the reflected light signal to determine the concentration of alcohol in the driver's breath, providing instant results. However, existing laser detection equipment still has some shortcomings.

[0003] Utility model patent CN206057173U discloses a vehicle-mounted laser alcohol detection device and system. The detection device includes a laser; a collimator connected to and matched to the laser; a gas absorption cavity for multiple reflections of the laser emitted from the collimator, including a plane mirror and a concave mirror with their reflective surfaces facing each other, the collimator being located outside the plane mirror on one side of the gas absorption cavity; a detector located outside the plane mirror on the other side of the gas absorption cavity, detecting and converting the laser signal with absorption information after multiple reflections into an electrical signal; and a signal processor connected to the detector, processing the electrical signal to generate an alcohol concentration signal. This improves the accuracy of alcohol detection while miniaturizing the device, enabling timely reminders to drivers for safe driving and sending the measured alcohol concentration to a mobile terminal to alert relevant personnel to stop drunk driving. However, while the above device can achieve alcohol detection, it cannot adjust the support range at the bottom of the device according to the usage environment, and existing laser alcohol detection devices cannot automatically block the laser detector after the extendable support structure at the bottom is retracted.

[0004] Therefore, we have made improvements to this and proposed a protective laser drunk driving detection device. Utility Model Content

[0005] The purpose of this invention is to address the problems of existing drunk driving laser detection devices that cannot automatically block the laser detector after the bottom extendable support structure is retracted, and that cannot adjust the support range of the bottom of the device according to the usage environment.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: A protective laser-based drunk driving detection device was developed to address the aforementioned issues.

[0007] The application is as follows: The device includes a bracket, on which an extension plate is slidably mounted. A rotating shaft is rotatably connected to the extension plate, and a support plate is mounted on the rotating shaft. A slip ring is provided on the top of the support plate, and the support plate and the slip ring are rotatably connected. A first electric push rod is mounted on the bracket, and a connecting ring is connected above the first electric push rod. A connecting rod is welded above the connecting ring, and the top of the connecting rod is rotatably connected to the slip ring. A second electric push rod is mounted on the slip ring, and a connecting block is provided above the second electric push rod. A laser detector is mounted on the connecting block, and a protective shell and a baffle are provided on the outside of the laser detector. A rotating sleeve is mounted on the protective shell, and a connecting plate is mounted on the rotating sleeve. A traction steel rope is wound around the rotating sleeve, and a rubber rod is connected to the bottom of the traction steel rope. The bottom of the rubber rod is connected to the connecting ring. A fixed shaft is fixedly provided in the middle of the protective shell, and a torsion spring is installed between the fixed shaft and the rotating sleeve.

[0008] As a preferred technical solution of this application, a motor is installed on the bracket, a first rotating wheel is fixedly connected to the output shaft of the motor, a second rotating wheel is provided on the side of the first rotating wheel, and the second rotating wheel and the first electric push rod are fixedly connected.

[0009] As a preferred technical solution of this application, guide plates are symmetrically arranged around the bracket, and the extension plate and the guide plates are slidably connected.

[0010] As a preferred technical solution of this application, the first rotating wheel and the second rotating wheel abut against each other, both the first rotating wheel and the second rotating wheel are made of rubber, and the side of the second rotating wheel is provided with longitudinal ridges.

[0011] As a preferred technical solution of this application, a transparent cover is fixedly connected to the laser detector, and the transparent cover, protective shell and fixed shaft are fixedly connected as an integral structure.

[0012] As a preferred technical solution of this application, the rotating sleeve, connecting plate and baffle are fixedly connected as an integral structure, and a gap is provided between the rotating sleeve and the fixed shaft.

[0013] As a preferred technical solution of this application, the connecting plate and the baffle are fixedly connected, and the baffle and the protective shell are slidably connected.

[0014] As a preferred technical solution of this application, a cleaning pad is fixedly connected to the inner wall of the baffle, and the inner diameter of the cleaning pad is equal to the outer diameter of the transparent cover.

[0015] As a preferred technical solution of this application, the baffle forms a sliding structure with the protective shell through a traction steel rope, a connecting ring and a connecting rod.

[0016] As a preferred technical solution of this application, the connecting rods are evenly distributed along the circumference of the slip ring, and the slip ring and the bracket are slidably connected.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. By setting up extension plates, rotating shafts, and support plates, the extension range of the bottom support structure of the device is adjusted to adapt to different environments, enhancing the overall stability of the device. When placed outdoors, the device can resist the interference of lateral winds, preventing the equipment from tipping over or shaking in severe weather. Furthermore, the extended support range allows the device to adapt to different road surfaces. By extending all four extension plates to a flat road surface, the device can be made more stable when performing laser drunk driving detection, solving the problem that existing detection devices cannot adjust the support range of the bottom of the device according to the usage environment.

[0018] 2. The protective shell, connecting plate, and baffle are designed to protect the laser detector. When the extension plates around the device retract, the slip ring moves upward, causing the traction steel rope and torsion spring to gradually change from a tense state to a relaxed state, which in turn causes the baffle to close automatically. This provides the device with dustproof and impact-proof functions when not in use, enhancing the safety of the device during use and solving the problem that existing drunk driving laser detection devices cannot automatically block the laser detector after the bottom extendable support structure is retracted.

[0026] Example 1: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this embodiment proposes a protective laser drunk driving detection device, including a bracket 1. An extension plate 6 is slidably mounted on the bracket 1, and a rotating shaft 7 is rotatably connected to the extension plate 6. A support plate 8 is mounted on the rotating shaft 7, and a slip ring 10 is provided on the top of the support plate 8. The support plate 8 and the slip ring 10 are rotatably connected. A first electric push rod 9 is mounted on the bracket 1, and a connecting ring 24 is connected above the first electric push rod 9. A connecting rod 25 is welded above the connecting ring 24, and the top of the connecting rod 25 is rotatably connected to the slip ring 10. A second electric push rod is mounted on the slip ring 10. A connecting block 12 is provided above the second electric push rod 11. A laser detector 13 is installed on the connecting block 12. A protective shell 15 and a baffle 18 are provided on the outside of the laser detector 13. A rotating sleeve 16 is installed on the protective shell 15. A connecting plate 17 is installed on the rotating sleeve 16. A traction steel rope 23 is wound around the rotating sleeve 16. A rubber rod 22 is connected to the bottom of the traction steel rope 23. The lower part of the rubber rod 22 is connected to the connecting ring 24. A fixed shaft 19 is fixedly installed in the middle of the protective shell 15. A torsion spring 20 is installed between the fixed shaft 19 and the rotating sleeve 16. The bracket 1 is used to support the entire device. When it is necessary to extend the extension plate 6 outward, the first electric push rod 9 is shortened, which drives the connecting ring 24, connecting rod 25 and slip ring 10 to move downward. The torsion spring 20 can then automatically reset the baffle 18 to the unfolded state. The device can change the initial open or closed state of the baffle 18 by adjusting the extension of the second electric push rod 11.

[0027] Example 2: The solution in Example 1 will be further described below with reference to its specific working method. like Figure 1 As shown, in a preferred embodiment, based on the above method, a motor 2 is further mounted on the bracket 1, a first rotating wheel 3 is fixedly connected to the output shaft of the motor 2, a second rotating wheel 4 is provided on the side of the first rotating wheel 3, the second rotating wheel 4 and the first electric push rod 9 are fixedly connected, guide plates 5 are symmetrically arranged around the bracket 1, the extension plate 6 is slidably connected to the guide plate 5, the first rotating wheel 3 and the second rotating wheel 4 abut against each other, the first rotating wheel 3 and the second rotating wheel 4 are both made of rubber, the side of the second rotating wheel 4 is provided with longitudinal ridges, the motor 2 is used to drive the first rotating wheel 3 to rotate, the first rotating wheel 3 is used to drive the second rotating wheel 4 to rotate, thereby driving the first electric push rod 9 to rotate, so that the device can change the initial position of the first electric push rod 9, the guide plate 5 ensures that the extension plate 6 can move straight, and when the extension plate 6 moves outward, it can enhance the stability of the device to adapt to the use scenario with strong wind.

[0028] like Figure 3As shown, in a preferred embodiment, based on the above method, a transparent cover 14 is fixedly connected to the laser detector 13. The transparent cover 14, the protective shell 15, and the fixed shaft 19 are fixedly connected as an integral structure. The rotating sleeve 16, the connecting plate 17, and the baffle 18 are fixedly connected as an integral structure. A gap is provided between the rotating sleeve 16 and the fixed shaft 19. The transparent cover 14 is used to protect the laser head of the laser detector 13, thereby enhancing the safety of the device during use.

[0029] like Figure 4 As shown, in a preferred embodiment, based on the above method, the connecting plate 17 and the baffle 18 are fixedly connected, the baffle 18 is slidably connected to the protective shell 15, and a cleaning pad 21 is fixedly connected to the inner wall of the baffle 18. The inner diameter of the cleaning pad 21 is equal to the outer diameter of the transparent cover 14. When the baffle 18 rotates, the outer surface of the transparent cover 14 can be wiped by the cleaning pad 21, thereby realizing the function of automatic cleaning when the protective structure is opened or closed.

[0030] like Figure 5 and Figure 6 As shown, in a preferred embodiment, based on the above method, the baffle 18 further comprises a sliding structure with the protective shell 15 via the traction steel rope 23, the connecting ring 24, and the connecting rod 25. The connecting rod 25 is evenly distributed along the circumference of the slip ring 10, and the slip ring 10 is slidably connected to the bracket 1. Figure 1 As can be seen, since the traction steel rope 23 is wound counterclockwise on the rotating sleeve 16, when the slip ring 10 moves upward, the traction steel rope 23 will automatically wind up under the action of the torsion spring 20, thereby achieving the protective function and facilitating the subsequent implementation of the protective function in the storage device.

[0031] Specifically, when using this protective laser drunk driving detection device: (e.g.) Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, bracket 1 is used to support the entire device. When the device is not in use, it is combined with... Figure 1 It can be seen that when the first electric push rod 9 extends, it can cause the connecting ring 24 to push the connecting rod 25 and the rubber rod 22. When the rubber rod 22 moves upward, the traction steel rope 23 automatically winds around the rotating sleeve 16 under the action of the torsion spring 20. The rotating sleeve 16 rotates counterclockwise, causing the connecting plate 17 and the baffle 18 to rotate counterclockwise on the protective shell 15, thereby protecting the laser detector 13. Furthermore, when the baffle 18 rotates, as... Figure 4 As shown, the cleaning pad 21 can automatically wipe away dust from the surface of the transparent cover 14, ensuring the detection accuracy for the next use.

[0032] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, when the device needs to adapt to different ground conditions or strong winds, shortening the first electric push rod 9 causes the connecting ring 24 to move downwards. The connecting rod 25 pulls the slip ring 10 downwards, causing the support plates 8 around the device to gradually tilt. This causes the rotating shaft 7 on the support plate 8 to rotate, and the extension plate 6 to slide within the guide plate 5, thereby increasing the support surface at the bottom of the device. The motor 2 drives the first rotating wheel 3 to rotate, and the first rotating wheel 3 drives the second rotating wheel 4 to rotate, which in turn drives the first electric push rod 9 to rotate. This allows the device to change the initial position of the first electric push rod 9, which, in conjunction with the second electric push rod 11, adjusts the initial tension of the traction steel rope 23, thereby changing the initial angle of the baffle 18.

[0033] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
