Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically to a vehicle-mounted mobile environmental monitoring device. Background Technology

[0002] With increasing environmental awareness, the demand for monitoring environmental quality such as air and noise is growing. To achieve rapid and flexible monitoring of the regional environment, vehicle-mounted mobile monitoring platforms have emerged. In existing technologies, these devices typically have a monitoring host installed on the roof or inside a vehicle. The host integrates various sensors (such as PM2.5, PM10, noise, temperature, and humidity sensors), and transmits data through an onboard power supply and a wireless communication module, thereby enabling environmental data collection while in motion.

[0003] Chinese utility model patent with publication number CN220398612U discloses a vehicle-mounted mobile environmental monitoring device. The door panel is designed to facilitate maintenance of the main body of the environmental monitoring device. The central control system greatly improves the operability of the device and the accuracy of the data. Various data can be viewed through the display screen. The rotating block is used to adjust the direction of the signal rod for better signal reception. The signal rod is designed to prevent the device from operating normally in areas with weak signals. The centralized wiring is designed to concentrate the circuitry, prevent wire cross-connection, and better protect the wiring.

[0004] However, in practical applications, it has been found that most of the aforementioned vehicle-mounted monitoring devices adopt a rigid installation method, that is, the monitoring host is directly and rigidly connected to the roof of the vehicle by bolts or brackets. During the vehicle's operation, especially on roads with poor conditions, continuous and severe vibrations will occur. This rigid connection method will transmit almost all of the vehicle's vibrations to the monitoring host with almost no attenuation, causing the delicate sensor components inside to be continuously subjected to impacts. Over time, this can easily cause the sensor measurement reference to shift, the connection lines to loosen, or even the components to be damaged, thereby affecting the accuracy of the monitoring data and the service life of the device. Utility Model Content

[0005] The purpose of this invention is to provide a vehicle-mounted mobile environmental monitoring device to solve the problems in the prior art where the rigid connection between the vehicle-mounted mobile monitoring device and the vehicle roof causes vibrations during vehicle operation to be directly transmitted to the precision sensors, resulting in distorted measurement data and shortened equipment lifespan.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a vehicle-mounted mobile environmental monitoring device, comprising a monitoring host and a mounting base for fixing the monitoring host to the roof of a vehicle, wherein an environmental monitoring sensor group is provided on the top of the monitoring host, and a power supply module and a communication module electrically connected to the environmental monitoring sensor group are provided inside the monitoring host.

[0007] It also includes a support plate fixedly installed at the bottom of the monitoring host. The bottom of the support plate is provided with telescopic rods of adjustable length that are spaced apart. The bottom of the telescopic rods is connected to the mounting base. A buffer spring is also fitted on the telescopic rods.

[0008] The left and right sidewalls of the support plate are symmetrically provided with mounting blocks one, and the inner opposite sidewall of the mounting base is provided with mounting blocks two that are opposite to the position of mounting blocks one. A lateral buffer is provided between mounting blocks one and mounting blocks two for movable connection.

[0009] Furthermore, the vertical cross-section of the mounting base is concave and made of aluminum alloy. The bottom of the left and right side walls of the mounting base is provided with a fixedly connected positioning plate. The positioning plate is provided with an adjustment hole, and the adjustment hole is provided with a fastening bolt that is locked onto the vehicle body.

[0010] Furthermore, the bottom of the mounting base is provided with shock-absorbing strips spaced apart along its length.

[0011] Furthermore, the environmental monitoring sensor group includes one or more of a particulate matter sensor, a wind speed sensor, and a wind direction sensor, and the monitoring host is also equipped with a monitoring camera.

[0012] Furthermore, the top end of the telescopic rod is movably hinged to the bearing plate, and the bottom end is movably hinged to the mounting base. The top of the buffer spring abuts against the bottom of the bearing plate, and the bottom of the buffer spring abuts against the mounting base.

[0013] Furthermore, the lateral buffer consists of a rotating column, a telescopic rod II, and a lateral spring. The rotating column is rotatably connected to the interior of the mounting block I and mounting block II via pins. The telescopic rod II is connected between the two rotating columns. The length of the telescopic rod II is adjustable. The lateral spring is sleeved on the telescopic rod II and its two ends abut against the rotating column.

[0014] Furthermore, the top of the left and right side plates of the mounting base are symmetrically provided with auxiliary rods. The vertical cross-section of the auxiliary rods is an arc shape with the opening facing downwards. Foldable rainproof cloths are provided on the two auxiliary rods, and the rainproof cloths are located above the monitoring host.

[0015] Furthermore, one end of the rainproof cloth is fixedly connected to one end of the two auxiliary rods, and the other end of the rainproof cloth is provided with a sliding ring sleeved on the auxiliary rod. The end of the rainproof cloth near the sliding ring is also provided with a magnetic suction component one, and the mounting base is provided with a magnetic suction component two that cooperates with the magnetic suction component one on the side near the sliding ring.

[0016] Compared with the prior art, the vehicle-mounted mobile environmental monitoring device provided by this utility model has a mounting base installed on the roof of the vehicle. The monitoring host is mounted on a support plate, and there are telescopic rods spaced apart between the support plate and the mounting base. The telescopic rods are fitted with buffer springs to buffer the impact of the vehicle in the vertical direction. Lateral buffers are set between the left and right side walls of the support plate and the side walls of the mounting base. The two ends of the lateral buffers are movably connected to the support plate and the mounting base, respectively. Thus, while the monitoring host moves up and down due to vibration, its up and down movement is also limited by the lateral buffers. More importantly, it can also effectively offset the lateral forces generated when the vehicle turns or changes lanes during driving, providing all-round shock absorption protection.

[0026] As attached Figure 1 To be continued Figure 5 As shown:

[0027] Example 1:

[0028] This utility model provides a vehicle-mounted mobile environmental monitoring device, including a monitoring host 1 and a mounting base 2 for fixing the monitoring host 1 to the roof of the vehicle. The top of the monitoring host 1 is provided with an environmental monitoring sensor group 3. The monitoring host 1 is internally provided with a power supply module and a communication module that are electrically connected to the environmental monitoring sensor group 3.

[0029] It also includes a support plate 4 fixedly installed at the bottom of the monitoring host 1. The bottom of the support plate 4 is provided with telescopic rods 5 that are spaced apart and adjustable in length. The bottom of the telescopic rods 5 is connected to the mounting base 2. A buffer spring 6 is also sleeved on the telescopic rods 5.

[0030] The left and right sidewalls of the support plate 4 are symmetrically provided with mounting blocks 1 7, and the inner opposite sidewalls of the mounting base 2 are provided with mounting blocks 2 8 that are opposite to the position of mounting blocks 1 7. A lateral buffer 9 is provided between mounting blocks 1 7 and mounting blocks 2 8 for movable connection.

[0031] It should be noted that: by setting the mounting base 2 on the roof of the vehicle, the monitoring host 1 is mounted on the support plate 4. There are telescopic rods 5 spaced apart between the support plate 4 and the mounting base 2. The telescopic rods 5 are fitted with buffer springs 6, which can buffer the impact of the vehicle in the vertical direction. Lateral buffers 9 are set between the left and right side walls of the support plate 4 and the side walls of the mounting base 2. The two ends of the lateral buffers 9 are movably connected to the support plate 4 and the mounting base 2, respectively. Thus, while the monitoring host 1 moves up and down due to vibration, its up and down movement can also be limited by the lateral buffers 9. More importantly, it can also effectively offset the lateral force generated when the vehicle turns or changes lanes during driving, providing all-round shock absorption protection.

[0032] In this embodiment: the vertical cross section of the mounting base 2 is concave and made of aluminum alloy. The bottom of the left and right side walls of the mounting base 2 is provided with a fixedly connected positioning plate 10. The positioning plate 10 is provided with an adjustment hole 11, and the adjustment hole 11 is provided with a fastening bolt 12 that is locked onto the vehicle body.

[0033] It should be noted that the mounting base 2 features a concave design to create a space for accommodating shock-absorbing components and wiring. The aluminum alloy material is lightweight, high-strength, and corrosion-resistant, making it suitable for use in automotive environments. The adjustment hole 11 on the positioning plate 10 is an elongated oval design, allowing for fine-tuning during installation to ensure the device is installed in the optimal position on the vehicle roof. The fastening bolt 12 features an anti-loosening design with elastic washers to prevent loosening under long-term vehicle vibration, improving installation reliability.

[0034] In this embodiment: the bottom of the mounting base 2 is provided with shock-absorbing strips 13 spaced apart along its length.

[0035] It should be noted that the damping strips 13 are made of rubber or polyurethane elastic material and are fixed to the bottom of the mounting base 2 by adhesive or clips. These damping strips 13 form an elastic buffer layer between the mounting base 2 and the roof surface, which can further attenuate high-frequency vibrations transmitted from the vehicle body, while increasing friction to prevent relative sliding between the mounting base 2 and the roof surface. The spaced distribution design ensures the damping effect while avoiding complete coverage that would affect the ventilation of the roof paint.

[0036] In this embodiment: the environmental monitoring sensor group 3 includes one or more of a particulate matter sensor 301, a wind speed sensor 302, and a wind direction sensor 303, and the monitoring host 1 is also equipped with a monitoring camera 14.

[0037] It should be noted that: the particulate matter sensor 301 uses the laser scattering principle to monitor air quality parameters such as PM2.5 and PM10 in real time; the wind speed sensor 302 uses the ultrasonic principle, featuring no moving parts and high accuracy; the wind direction sensor uses the electronic compass principle to accurately determine wind direction. The monitoring camera 14 uses a wide-angle high-definition lens to record the surrounding environment of the vehicle in real time, providing visual evidence for environmental monitoring data. The integration of multiple sensors realizes comprehensive environmental monitoring functions, meeting diverse monitoring needs.

[0038] In this embodiment: the top end of the telescopic rod 5 is movably hinged to the bearing plate 4, and the bottom end is movably hinged to the mounting base 2. The top of the buffer spring 6 abuts against the bottom of the bearing plate 4, and the bottom of the buffer spring 6 abuts against the mounting base 2.

[0039] It should be noted that the telescopic rod 5 consists of two rods of different diameters. The smaller diameter rod can move up and down on the larger diameter rod. The telescopic rod 5 is connected to the bearing plate 4 and the mounting base 2 via a ball joint, allowing for slight deflection in all directions and avoiding a rigid connection. The buffer spring 6 adopts a variable pitch design, with low initial stiffness to absorb small vibrations, and increased stiffness in the later stage to effectively limit large displacements. This connection method forms a dual buffer system: the telescopic rod 5 provides the main support and limiting function, while the buffer spring 6 provides elastic damping. The two work together to ensure both support stability and excellent damping effect.

[0040] In this embodiment: the lateral buffer 9 is composed of a rotating column 901, a telescopic rod 902, and a lateral spring 903. The rotating column 901 is rotatably connected to the interior of the mounting block 7 and the mounting block 8 respectively by a pin. The telescopic rod 902 is connected between the two rotating columns 901. The length of the telescopic rod 902 is adjustable. The lateral spring 903 is sleeved on the telescopic rod 902 and its two ends abut against the rotating column 901.

[0041] It should be noted that the rotating column 901 is connected by a precision pin, allowing for flexible rotation without any wobble or play. The telescopic rod 902 also consists of two rods of different diameters; the smaller diameter rod can move left and right on the larger diameter rod. The lateral spring 903 adopts an opposing design, with one end rotating left and the other right to prevent torsion. This design enables the lateral buffer 9 to adapt to lateral forces in different directions, providing stable lateral support during vehicle turning, crosswinds, and other conditions, preventing excessive lateral swaying of the monitoring host 1.

[0042] In this embodiment: auxiliary rods 15 are symmetrically provided on the top of the left and right side plates of the mounting base 2. The vertical cross section of the auxiliary rods 15 is an arc shape with the opening facing downwards. Foldable rainproof cloths 16 are provided on the two auxiliary rods 15. The rainproof cloths 16 are located above the monitoring host 1.

[0043] It should be noted that the auxiliary rod 15 is made of lightweight aluminum alloy tubing, bent into shape. The arc design ensures structural strength and provides good support for the rainproof cloth 16. The rainproof cloth 16 is made of waterproof coated fabric, which has the characteristics of being waterproof, UV resistant, and weather resistant. In rainy or snowy weather, the rainproof cloth 16 can be unfolded to cover the monitoring host 1, preventing rainwater from directly wetting the equipment, especially protecting the sensor air inlet and the lens of the monitoring camera 14 from rainwater, ensuring that the equipment can still work normally in severe weather.

[0044] In this embodiment: one end of the rainproof cloth 16 is fixedly connected to one end of the two auxiliary rods 15, and the other end of the rainproof cloth 16 is provided with a sliding ring 17 sleeved on the auxiliary rods 15. The end of the rainproof cloth 16 near the sliding ring 17 is also provided with a magnetic suction component 18. The mounting base 2 is provided with a magnetic suction component 2 19 that cooperates with the magnetic suction component 18 on the side near the sliding ring 17.

[0045] It should be noted that: the sliding ring 17 is made of engineering plastic with a smooth inner wall, allowing it to slide easily on the auxiliary rod 15; the magnetic components 18 and 19 are made of neodymium iron boron permanent magnets, which have strong magnetic force and good durability. When the rainproof cloth 16 needs to be unfolded, simply push the sliding ring 17 along the auxiliary rod 15 to the other end, and the magnetic components 18 and 19 will automatically engage and fix together.

[0046] To retract the rain cover 16, simply pull apart magnetic attachment 18 and magnetic attachment 19 to push it back into place. This design allows for quick unfolding and retraction of the rain cover 16 without the need for additional tools, making it convenient and practical while protecting the equipment without compromising its aesthetics.

[0047] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
