A portable environmental monitoring device

Abstract

This application provides a portable environmental monitoring device, relating to the field of environmental monitoring technology, comprising: a housing having an inner cavity. This application achieves adaptive stability protection through the coordinated action of a support frame elastic deformation mechanism and a bridging frame dynamic clamping mechanism: the device's gravity triggers the support part to sink, forcing the pre-reinforced elastic part to compress in a specific direction and driving the arc-shaped part to deform, which in turn drives the rolling mechanism to push the bridging frame to squeeze the device's side wings, forming a mechanical lock; simultaneously, a gradient buffer platform matching the arc-shaped part's deformation trajectory cooperatively absorbs energy, allowing the transport impact force to be gradually dissipated through elastic dissipation and damping attenuation, ultimately achieving closed-loop buffer protection for the device in dynamic environments.

Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and more specifically, to a portable environmental monitoring device. Background Technology

[0002] With the diversification of environmental monitoring needs, portable environmental monitoring equipment has become widely used in air quality monitoring, industrial pollution source monitoring, and emergency disaster response due to its advantages of flexible deployment, real-time data acquisition, and low cost. Traditional environmental monitoring equipment often adopts a fixed architecture, resulting in large size and complex maintenance, making it difficult to adapt to the dynamic monitoring needs of mobile scenarios. In recent years, breakthroughs in integrated sensor technology, low-power circuit design, and wireless communication technology have driven the miniaturization and intelligentization of portable devices. These devices typically incorporate multi-parameter sensors (such as PM2.5, temperature and humidity, and VOCs), GPS positioning modules, and lithium battery power systems. They can achieve remote data transmission via Bluetooth or 4G networks, meeting the rapid response needs of outdoor operations, environmental law enforcement, and personal health protection scenarios.

[0003] Portable environmental monitoring equipment has reliability design flaws throughout its transportation and use cycle. Specifically, during transportation, external forces such as vibration and collision can cause the fixing brackets of internal precision components (such as optical sensors and gas detection units) to loosen, leading to deviations in sensor calibration parameters and directly affecting the accuracy of monitoring data. At the same time, the equipment shell is mostly made of ordinary plastic or aluminum alloy, which, although providing basic dust and water resistance, lacks a cushioning structure against impacts, making it prone to problems such as circuit board solder joint detachment and poor battery contact.

[0004] Therefore, we have made improvements to this and proposed a portable environmental monitoring device. Utility Model Content

[0005] In order to achieve the above-mentioned objectives, this utility model provides a portable environmental monitoring device to improve the aforementioned problems.

[0006] The application is as follows:

[0007] include:

[0008] The box has an internal cavity;

[0009] The receiving frame, symmetrically arranged in the inner cavity of the box, is divided into:

[0010] The arc-shaped part is fixedly installed to the inner wall of the bottom surface of the box and extends gradually away from both sides of the box to form an arc shape.

[0011] The receiving part is arranged adjacent to both ends of the arc-shaped part, forming an arc-shaped structure with the arc-shaped part;

[0025] In the scheme of this application:

[0026] To address the problems in the prior art, this application achieves adaptive stability protection through the coordinated action of the elastic deformation mechanism of the receiving frame and the dynamic clamping mechanism of the bridging frame: the gravity of the equipment triggers the sinking of the receiving part, forcing the pre-reinforced elastic part to compress in a specific direction and driving the arc-shaped part to deform, which in turn drives the rolling mechanism to push the bridging frame to squeeze the side wings of the equipment to form a mechanical lock; at the same time, the gradient buffer platform matching the deformation trajectory of the arc-shaped part cooperates to absorb energy, so that the transfer impact force is gradually dissipated through elastic dissipation and damping attenuation, ultimately realizing closed-loop buffer protection of the equipment in the dynamic environment.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0033] For an example, please refer to... Figure 1 , Figure 2 and Figure 3 A portable environmental monitoring device, comprising:

[0034] Box 1 has an inner cavity;

[0035] The receiving frame 2 is symmetrically arranged in the inner cavity of the box body 1, and is divided into:

[0036] The arc-shaped portion 21 is fixedly disposed to the inner wall of the bottom surface of the box body 1 and extends in an arc shape gradually away from both sides of the box body 1;

[0037] The receiving part 22 is arranged adjacent to both ends of the arc-shaped part 21, forming an arc-shaped structure with the arc-shaped part 21;

[0038] The elastic part 23 is provided at the junction of the arc-shaped part 21 and the receiving part 22;

[0039] A sliding groove 24 is provided on the adjacent surface between the arc-shaped portion 21 and the receiving portion 22;

[0040] The bridging frame 3 is fitted onto the two receiving frames 2 and is set perpendicular to the receiving frames 2;

[0041] The sliding block 31 is disposed on the bridging frame 3 and contacts the sliding groove 24. Its contact surface has an arc-shaped contact surface with the same arc-shaped trend as the arc-shaped part 21.

[0042] The elastic element 32 is disposed on the bridging frame 3 and points towards the receiving part 22, and its end has a ball that contacts the receiving part 22.

[0043] When the device is placed on the receiving part 22, gravity squeezes the receiving part 22 and forces the arc-shaped part 21 to deform horizontally after contacting the inner bottom surface of the box body 1, and causes the bridging frame 3 to move in the direction of the squeezing device.

[0044] When the device is placed on the receiving part 22, its gravity first acts on the cushioning cotton 4 to disperse local pressure, and then presses down on the receiving part 22. At this time, the pre-compressed honeycomb elastic rubber of the elastic part 23 is further squeezed, and the internal spiral nylon fiber mesh inhibits the lateral tearing of the rubber, while uniformly transmitting the pressure to both ends of the arc-shaped part 21. The arc-shaped part 21 is forced to bend and deform towards the bottom surface of the box 1. As its curvature gradually flattens, the arc-shaped bottom surface contacts the buffer platform of the inner wall of the box 1: the increasing arc height makes the deformation hindered in stages, and the covering damping silicone layer absorbs high-frequency vibration, forming the first-level buffer.

[0045] As the arc-shaped part 21 deforms, the sliding groove 24 shifts with the curvature of the arc-shaped part 21, driving the rollers of the sliding block 31 to roll along the arc-shaped groove of the sliding groove 24. The rolling mechanism converts sliding friction into rolling friction, propelling the bridging frame 3 to move smoothly toward the equipment. At this time, the balls at the end of the elastic element 32 continuously press against the receiving part 22, ensuring that the displacement of the bridging frame 3 precisely corresponds to the weight of the equipment. The frame of the bridging frame 3 and the L-shaped plate 33 form an enclosing structure: the bent edge of the L-shaped plate 33 rises along the side wall of the box 1, clamping the side wings of the equipment together with the cushioning cotton 4, achieving three-dimensional fixation.

[0046] If an impact occurs during transport, the inertial force of the equipment intensifies the sinking of the receiving part 22, and the honeycomb rubber of the elastic part 23 extends directionally through the air cavity, quickly dissipating the impact energy; at the same time, the arc-shaped part 21 presses further against the buffer platform, and the damping silicone layer generates a deformation hysteresis effect, converting the shock wave into heat energy for dissipation. At this time, the bridging frame 3 continuously fine-tunes the clamping force due to the rolling feedback of the sliding block 31, preventing the equipment from shaking; the elastic contact surface between the L-shaped plate 33 and the buffer cotton 4 compensates for high-frequency micro-vibrations, preventing wear on the equipment surface.

[0047] Also includes:

[0048] L-shaped plate 33 is set on the top surface of the receiving frame 2, and its bend is directed toward the side of the box body 1;

[0049] The cushioning cotton 4 is placed on the top surface of the receiving part 22 and contacts the L-shaped surface of the L-shaped plate 33;

[0050] When the bridging frame 3 is squeezed, since the contact surface between the sliding block 31 and the sliding groove 24 is arc-shaped, it will gradually tilt during the process of squeezing the device, causing the L-shaped cavity of the L-shaped plate 33 to gradually contact the buffer cotton 4. As a result, the device is less affected by shaking during the process of being squeezed or shaken, and this process releases part of the elasticity of the elastic element 32. It should be added that the elastic element 32 can be a spring telescopic rod.

[0051] The elastic part 23 includes a pre-compressed honeycomb elastic rubber with a spiral nylon fiber mesh embedded inside, and the outer surface of the rubber is covered with a metal insert that is in contact with the arc-shaped part 21 and the receiving part 22.

[0052] The honeycomb structure enhances multi-directional deformation capability, the nylon fiber mesh inhibits rubber tearing, and the metal inserts achieve uniform stress transmission, enabling the elastic part 23 to maintain structural integrity during repeated deformation and extend its service life.

[0053] A rolling mechanism is provided between the sliding block 31 and the sliding groove 24. The rolling mechanism includes multiple rows of rollers embedded in the arc-shaped contact surface of the sliding block 31, and an arc-shaped wheel groove in the sliding groove 24 that matches the trajectory of the rollers.

[0054] By replacing sliding friction with rolling friction, the moving resistance of the bridging frame 3 is reduced, while eliminating the risk of mechanical jamming.

[0055] The inner wall of the bottom surface of the box 1 is provided with an arc-shaped buffer platform that matches the deformation trajectory of the arc-shaped part 21. The surface of the buffer platform is covered with a damping silicone layer, and the arc height increases along the deformation direction of the arc-shaped part 21. The increasing arc height bears the impact force in stages.

[0056] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
