Description

Technical Field

[0001] This utility model relates to a hazardous gas detection device, and in particular to a vehicle hazardous gas detection device. Background Technology

[0002] As cars become more common and are used more frequently, the incidence of accidents caused by driver negligence, such as carbon monoxide poisoning and people trapped in their vehicles, is also rising.

[0003] To prevent accidents, Taiwan Patent No. 202203167 provides a car gas detection device. The gas detection unit detects the gas concentration inside the vehicle. When the gas concentration inside the vehicle exceeds a preset threshold, the control unit can activate the warning unit to issue a warning effect, reminding the occupants to open the windows for ventilation or stop driving and get out of the car in time, thus preventing accidents from happening in advance.

[0004] However, this car gas detection device only provides a single-stage alarm. If the occupants are already unconscious from gas poisoning and unable to save themselves, it cannot effectively alert bystanders to assist in the rescue, resulting in poor warning effectiveness. Furthermore, its power supply comes from the vehicle's battery, requiring wiring along the vehicle body for installation, making it complex and difficult to install.

[0005] Therefore, how to improve the above-mentioned problems is the primary issue that this utility model aims to solve. Utility Model Content

[0006] The main purpose of this utility model is to provide a vehicle-mounted hazardous gas detection device with a two-stage alarm function, which effectively alerts people inside the vehicle and bystanders, ensuring that people inside the vehicle evacuate in time to avoid danger.

[0007] To achieve the aforementioned objectives, the present invention adopts the following technical solution:

[0008] A vehicle-mounted hazardous gas detection device, comprising:

[0009] A detection host can be placed in a vehicle interior. The detection host includes a start-up unit, a control unit, a hazardous gas detection unit, an alarm unit, a wireless transmission unit, and a power supply unit. It also includes a housing. The aforementioned components are installed inside the housing. The power supply unit is used to supply power to the components.

[0010] The starting unit is used to sense the vibration of a vehicle compartment in order to activate the power supply unit to provide power.

[0011] The power unit has a solar panel disposed on the surface of the housing and a battery for storing the electrical energy generated by the solar panel.

[0012] The harmful gas detection unit is used to detect the concentration of harmful gases in the vehicle interior and to send the detection data back to the control unit.

[0013] The control unit presets a concentration threshold. When the detected data exceeds the concentration threshold, the control unit is triggered to execute a first-stage alarm mode. The first-stage alarm mode is that the control unit activates the warning unit to issue a warning signal to alert the occupants of the vehicle.

[0014] An alarm is installed outside the vehicle compartment and has a wireless receiving unit. When the alarm unit continuously emits an alarm signal for a preset duration, it triggers the control unit to execute a second-stage alarm mode. In the second-stage alarm mode, the control unit sends a control signal to the wireless receiving unit through the wireless transmission unit to activate the alarm and alert bystanders.

[0015] Preferably, the detection host is externally provided with an adjustment control, which is electrically connected to the control unit and is used to adjust the set concentration threshold.

[0016] Preferably, the detection host has a display unit electrically connected to the control unit for displaying the concentration of harmful gases, time, and temperature.

[0017] Preferably, the detection host is provided with an alarm cancellation key, which is electrically connected to the control unit to output a cancellation signal to the control unit to turn off the alarm unit.

[0018] Preferably, the starting unit is a vibration sensor electrically connected to the power supply unit and the power supply unit, used to convert vibrations in the vehicle interior into electrical signals and transmit them to the control unit to activate power control and supply power. If the control unit does not receive an electrical signal from the starting unit for a preset signal reception time, it stops power control to turn off the power supply.

[0019] Preferably, the warning unit includes a buzzer and a warning light, the warning light being disposed in the housing.

[0020] Preferably, the alarm is connected to the vehicle's battery and is powered by an audible and / or visual alarm.

[0021] Preferably, the alarm is battery powered and provides audible and / or visual alarms.

[0022] Preferably, the harmful gas detection unit is for detecting carbon monoxide concentration.

[0023] Preferably, the harmful gas detection unit is for detecting carbon dioxide concentration.

[0024] Compared with the prior art, this utility model has significant advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly involves placing a detection host in the vehicle interior to detect the concentration of harmful gases inside the vehicle. When the control unit determines that the concentration of harmful gases exceeds a preset threshold, it triggers the first-stage alarm mode, activating the warning unit to issue a warning signal to alert the occupants of the vehicle to open the windows for ventilation or stop driving and get out of the vehicle in time to avoid subsequent dangers. When the warning unit continues to issue a warning signal for a preset duration, it triggers the second-stage alarm mode, in which the alarm sounds to alert bystanders to assist the occupants of the vehicle in escaping. Through the phased alarm, it effectively alerts people inside and outside the vehicle to prevent danger from occurring.

[0025] The above-mentioned objectives and advantages of this utility model can be readily understood from the following detailed description and accompanying drawings of the selected embodiments. Attached Figure Description

[0026] Figure 1 This is a three-dimensional structural diagram of the present invention.

[0027] Figure 2 This is a block diagram of the present invention.

[0028] Figure 3 This is a schematic diagram of the operation process of this utility model. Detailed Implementation

[0029] Please see Figure 1 and Figure 2 This is a preferred embodiment of the vehicle hazardous gas detection device provided by this utility model, which mainly consists of a detection host 100 and an alarm 200, wherein:

[0030] The detection host 100 is placed in the vehicle interior to detect the concentration of harmful gases inside the vehicle and issue warnings. Specifically, the detection host 100 includes a start-up unit 1, a control unit 2, a harmful gas detection unit 3, a warning unit 4, a wireless transmission unit 5, and a power supply unit 6. It also includes a housing 7, in which the aforementioned components are installed. The power supply unit 6 supplies power to the aforementioned components.

[0031] The starting unit 1 is electrically connected to the power supply unit 6 and the control unit 2. It senses vibrations inside the vehicle and converts them into electrical signals, which are then transmitted to the control unit 2 to trigger the control unit 2 to activate the power supply. The power supply unit 6 has a solar panel 61 mounted on the surface of the housing 7 and a battery 62 that stores the electrical energy generated by the solar panel 61. The power supply is maintained by the solar panel 61, eliminating the need for additional wiring to connect to an external power source or the vehicle's battery. This makes it easy to install and allows it to be placed in any location according to the driver's needs.

[0032] In this embodiment, the starting unit 1 is a vibration sensor (such as SW-420 or MPU6050). When the control unit 2 is in standby mode, the power supply unit 6 only supplies power to the starting unit 1 and the control unit 2. When the starting unit 1 senses vibration in the vehicle interior, it sends an electrical signal to the control unit 2. The control unit 2 determines that this electrical signal is a valid vibration and then activates power control, thereby supplying power to the hazardous gas detection unit 3, the warning unit 4, and the wireless transmission unit 5. If the control unit 2 does not receive an electrical signal from the starting unit 1 for a preset signal reception time, it indicates that the vehicle has been turned off and the occupants have left the vehicle interior. The control unit 2 then stops power control to shut off the power supply, reducing unnecessary power consumption and extending the lifespan of the power supply unit 6. Further, the control unit 2 is preferably a microcontroller (MCU).

[0033] Please see Figure 2 As shown, the hazardous gas detection unit 3 is electrically connected to the control unit 2, detecting the concentration of hazardous gases such as carbon monoxide (CO) or carbon dioxide (CO2) inside the vehicle and feeding back detection data to the control unit 2. The control unit 2 has a built-in concentration threshold. When the detected data exceeds the concentration threshold, the control unit 2 is triggered to execute a first-stage alarm mode. In the first-stage alarm mode, the control unit activates the warning unit to issue a warning signal to alert the occupants of the vehicle. Further, the outer casing 7 has an adjustment control 71, which is electrically connected to the control unit 2, allowing the user to adjust the set concentration threshold according to the type of hazardous gas detected. If the detected hazardous gas is carbon monoxide, the threshold range is set from 0 ppm to 400 ppm; if the detected hazardous gas is carbon dioxide, the threshold range is set from 0 ppm to 10000 ppm. Because carbon monoxide is a highly hazardous gas, with a concentration of 400 ppm posing a life-threatening risk, and carbon dioxide concentrations exceeding 10,000 ppm posing a risk of respiratory acidosis, the preset threshold ranges for both carbon monoxide and carbon dioxide are within safe concentration ranges to ensure that drivers are alerted in advance and to avoid dangerous situations.

[0034] In addition, the detection host 100 is also equipped with a display unit 8, which is electrically connected to the control unit 2. In this embodiment, the display unit 8 is a display screen disposed on the housing 7. The control unit 2 outputs information signals to the display unit 8, which displays the concentration of harmful gases, time, and interior temperature of the vehicle, visualizing the interior environmental data and allowing the driver to intuitively understand the current interior environmental status.

[0035] The warning signals emitted by the warning unit 4 include audible and visual alarms. In this embodiment, the warning unit 4 includes a buzzer 41 and a warning light 42, with the warning light 42 located on the exterior of the housing 7. When the control unit 2 activates the warning unit 4, the buzzer 41 emits a buzzing sound, and the warning light flashes to warn occupants to open the windows for ventilation or turn off the engine and exit the vehicle to avoid poisoning from harmful gases. In other feasible embodiments, the control unit 2 may also control the display unit 8 to flash to warn occupants.

[0036] The detection unit 100 also includes an alarm deactivation button 72, which is located on the housing 7 and electrically connected to the control unit 2. When the occupants are alert and promptly open the windows for ventilation or turn off the engine and exit the vehicle, they can press the alarm deactivation button 72 to output a deactivation signal to the control unit 2 to disable the alarm unit 4. If the occupants have lost the ability to deactivate the alarm, or if a young child or pet is trapped inside the vehicle and cannot deactivate the alarm themselves, and the alarm unit 4 continues to emit an alarm signal for a preset duration, it triggers the control unit 2 to execute a second-stage alarm mode. In the second-stage alarm mode, the control unit 2 sends a control signal through the wireless transmission unit 5. The wireless receiving unit 201 of the alarm 200 receives the control signal and activates the alarm 200 to alert bystanders to assist the occupants in escaping danger. It should be noted that the alarm 200 is located outside the vehicle, and its power supply unit 204 can be powered by a battery or connected to the vehicle's battery to provide sound and / or light alarms. In this embodiment, the power supply unit 204 of the alarm 200 is a battery, and it also has a loudspeaker 202 and a warning light group 203. The power supply unit 204 supplies power to the loudspeaker 202 and the warning light group 203 to emit sound and light to alert people outside the vehicle.

[0037] For practical applications of this utility model comprised of the aforementioned components, please refer to [link / reference needed]. Figure 2 and Figure 3 As shown, the detection unit 100 is placed in a location within the vehicle interior where it can be illuminated by external light (i.e., within the vehicle's passenger compartment), while the alarm 200 is located outside the vehicle. When the vehicle starts or occupants move, causing vibrations in the vehicle body, the activation unit 1 converts the vibrations inside the vehicle interior into electrical signals and transmits them to the control unit 2. When the control unit 2 determines that the electrical signal represents valid vibration, it activates the power control, supplying power to the hazardous gas detection unit 3, the warning unit 4, and the wireless transmission unit 5. At this time, the hazardous gas detection unit begins to detect the concentration of hazardous gases inside the vehicle interior and continuously feeds back the detection data to the control unit 2.

[0038] When control unit 2 determines that the detected data exceeds the concentration threshold, it triggers the execution of the first-stage alarm mode. Control unit 2 activates warning unit 4, causing buzzer 41 and warning light 42 to emit audible and visual warning signals respectively, to alert occupants to open windows for ventilation or stop driving and leave the vehicle. After receiving the alarm, occupants can press the alarm cancellation button 72 to pause the alarm, open windows for ventilation, or stop driving and leave the vehicle. If occupants do not perform the above actions after canceling the alarm, and control unit 2 determines that the data continuously detected by harmful gas detection unit 3 still exceeds the concentration threshold, it re-executes the first-stage alarm mode and activates warning unit 4 again to warn occupants.

[0039] If the occupants of the vehicle are unable to deactivate the alarm, or if young children or pets are trapped inside the vehicle and unable to deactivate the alarm themselves, the control unit 2 determines that the warning signal emitted by the warning unit 4 has been continuously emitted for a preset duration and executes the second-stage alarm mode. That is, the control unit 2 sends a control signal to the wireless receiving unit 201 of the alarm 200 through the wireless transmission unit 5 to activate the alarm 200 to alert bystanders outside the vehicle and assist the occupants of the vehicle to escape danger in time.

[0040] In summary, the vehicle hazardous gas detection device provided by this utility model achieves the following improvements:

[0041] First, a phased alarm system ensures the safety of occupants. This invention first uses a first-stage alarm mode to warn occupants of a dangerous environment inside the vehicle. If the first-stage alarm cannot be deactivated, it confirms that the occupants have lost or are unable to escape danger, and activates a second-stage alarm mode to warn bystanders outside the vehicle. This helps bystanders to promptly discover the occupants' predicament and provide assistance, ensuring that the occupants can escape danger in a timely manner.

[0042] Secondly, the installation is simple and convenient; the detection host of this utility model generates electricity through a solar power cell and stores electrical energy in a battery, without the need for additional wiring to connect to the power supply on the vehicle body, making it easy to install and allowing users to place the detection host in a suitable location according to their needs.

[0043] Third, it operates with low energy consumption and extends service life. This utility model senses vibration in the vehicle compartment through the starting unit, triggering the control unit to turn on the power control to supply power. If the control unit does not receive a telecommunication signal from the starting unit for a preset signal reception time, it stops the power control to turn off the power supply, reducing unnecessary power consumption and extending the service life of the power supply unit.

[0044] The above embodiments are disclosed only to illustrate the present utility model and are not intended to limit the present utility model. Any substitution of equivalent elements should still fall within the scope of the present utility model.

[0045] In summary, this invention enables those skilled in the art to understand that it can indeed achieve the aforementioned objectives, and thus complies with the provisions of the Patent Law. Therefore, this application is filed in accordance with the law.
