Description

Technical Field

[0001] This utility model relates to the field of radar technology, and in particular to a vehicle-mounted lidar particulate matter monitoring device. Background Technology

[0002] A vehicle-mounted lidar particulate matter monitor is an environmental monitoring device that uses lidar technology to monitor particulate matter in the air in real time. This monitor is usually mounted on the roof of a mobile monitoring vehicle, which uses the mobility of the vehicle to continuously measure particulate matter concentration in a specific area or route.

[0003] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0004] Currently, most vehicle-mounted lidar particulate matter monitoring devices use a rigid connection structure to directly fix the lidar to the vehicle roof. While this design ensures the stability of the lidar to a certain extent, it is prone to damage when facing complex and changing road conditions, especially when the monitoring vehicle is traveling on bumpy roads. This is because the rigid connection structure cannot effectively absorb and disperse the impact force caused by vehicle vibration, and the lidar and its delicate optical components are easily damaged. This not only increases the maintenance cost of the equipment, but may also affect the continuity and accuracy of the monitoring data.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model proposes a vehicle-mounted lidar particulate matter monitoring device, which solves the problems mentioned in the background technology.

[0007] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0008] A vehicle-mounted lidar particulate matter monitoring device includes a particulate lidar main body and two parallel mounting frames for mounting the particulate lidar main body on the roof of the vehicle.

[0009] The assembly frame includes a T-shaped slide seat and two spring dampers, both bolted to the top of the T-shaped slide seat and vertically mounted, as well as two clamping seats, each secured to the top of the two spring dampers with nuts and symmetrically distributed.

[0010] The clamping seat consists of a support plate and a vertical plate welded to the top of the support plate. An angle groove structure is formed between the inner side of the vertical plate and the top surface of the support plate for the bottom side of the particulate matter lidar body to be clamped. A positioning hole is provided on the outer side of the vertical plate and on the support plate for the top of the spring damper to be installed through.

[0011] Preferably, the device also includes two flanged structures welded to the inner sides of the two clamping seats, with a tie rod threaded between the two flanged structures. The introduction of the flanged structures and the tie rod further enhances the stability and clamping force of the clamping seats, making the lidar more stable during operation. In the actual installation process, the two clamping seats, the two flanged structures, and the tie rod can be pre-clamped as a separate component to the bottom of the particulate lidar body to further optimize installation convenience.

[0012] Preferably, both ends of the T-shaped slide seat are fitted with plugs. The plugs seal the ends of the T-shaped slide seat, limiting the range of movement of the spring damper on the T-shaped slide seat. Simultaneously, bolts for locking the spring damper can be pre-assembled within the T-shaped slide seat to form a prefabricated component, further improving the convenience and flexibility of the overall assembly frame.

[0013] Preferably, the bottom of both spring dampers is covered with an adhesive anti-slip pad. The anti-slip pad increases the friction between the bottom of the spring damper and the T-shaped slide seat, thereby ensuring that the spring damper is securely fixed to the T-shaped slide seat.

[0014] The beneficial effects of this utility model are:

[0015] The technical solution of this utility model, by introducing a spring damper into the assembly frame, can effectively absorb and disperse the impact force caused by vehicle vibration, protect the lidar and its precision optical components from damage, thereby extending the service life of the equipment. At the same time, the design of the clamping seat and the T-shaped slide seat makes the assembly frame easier to disassemble and debug, and can flexibly adapt to lidars of different sizes and specifications to be mounted on the top of the mobile vehicle.

[0028] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a vehicle-mounted lidar particulate matter monitoring device, comprising a particulate lidar body 100 and two parallel mounting frames 200 for mounting the particulate lidar body 100 on the roof of a vehicle. Each mounting frame 200 includes a T-shaped slide seat 210 and two spring dampers 230, each bolted to the top of the T-shaped slide seat 210 and vertically mounted, and two spring dampers 230, each bolted to the top of the T-shaped slide seat 210 and vertically mounted, and two spring dampers 230, each nut 240, respectively. Two spring dampers 230 are symmetrically distributed on top of each other and clamping seats 250. Each clamping seat 250 consists of a support plate 2510 and a vertical plate 2520 vertically welded to the top of the support plate 2510. The inner side of the vertical plate 2520 and the top surface of the support plate 2510 form a corner groove structure for the bottom side of the particulate matter lidar body 100 to be clamped. The outer side of the vertical plate 2520 and the support plate 2510 are provided with positioning holes 2530 for the top of the spring dampers 230 to be installed through.

[0030] Based on the above structural configuration, the vehicle-mounted lidar particulate matter monitoring device consists of a particulate lidar body 100 and two mounting brackets 200. The particulate lidar body 100 is mounted on the roof of a mobile monitoring vehicle via the two mounting brackets 200. Each mounting bracket 200 consists of a T-shaped sliding seat 210, two spring dampers 230, four bolts 220, two clamping seats 250, and two nuts 240. The T-shaped sliding seat 210 serves as the basic support structure, securely mounted on the roof of the mobile monitoring vehicle. The two spring dampers 230 play a crucial role in shock absorption. The two symmetrically distributed clamping seats 250 are used to clamp and fix the particulate lidar body 100. Within the clamping seats 250, the inner side of the upright plate 2520 is connected to the support... The corner groove structure formed between plates 2510 ensures that the lidar can be securely mounted therein, while the positioning hole 2530 on the support plate 2510 on the outer side of the upright plate 2520 allows the top of the spring damper 230 to be installed through. This vehicle-mounted lidar particulate matter monitoring device mainly relies on the shock absorption characteristics of the spring damper 230 in the mounting frame 200 and the stable clamping function of the clamping seat 250 to effectively protect and stably monitor the lidar body under complex road conditions. Specifically, during operation, when the vehicle travels on complex and changing road conditions, especially bumpy sections, the vehicle will generate vibrations and impacts. These vibrations and impacts are first absorbed by the spring damper 230 in the mounting frame 200. The spring damper 230, utilizing its internal spring and damping elements, effectively absorbs and disperses these impact forces, transforming them into a compression and recovery process of the spring. This reduces the direct impact on the lidar body. Through the shock absorption effect of the spring damper 230, the lidar body and its precision optical components are protected from damage, ensuring the long-term stable operation of the equipment and the accuracy of the monitoring data. During installation and commissioning, since the bolt 220 can slide flexibly within the T-shaped sliding seat 210 when loosened, the operator can flexibly adjust the distance between the two spring dampers 230 after loosening the bolt 220, thereby adjusting the distance between the two clamping seats 250 to ensure that the two clamping seats 250 can effectively handle particulate matter. The mounting frame 200 provides a secure clamping mechanism, allowing it to flexibly accommodate different sizes and specifications of particulate matter lidar main bodies 100. Furthermore, the spring damper 230 is secured to the T-shaped slide seat 210 with bolts 220, and the clamping seat 250 is secured to the top of the spring damper 230 with nuts 240. The components are connected using a detachable structure, facilitating routine maintenance, parts replacement, and the assembly and disassembly of the particulate matter lidar main body 100. This vehicle-mounted lidar particulate matter monitoring device, by introducing the spring damper 230 into the mounting frame 200, effectively absorbs and disperses the impact force from vehicle vibrations, protecting the lidar and its delicate optical components from damage, thereby extending the device's service life.The design of the clamping base 250 and the T-shaped slide rail base 210 makes the assembly, disassembly, and adjustment of the mounting frame 200 more convenient, and can flexibly adapt to the mounting of LiDARs of different sizes and specifications on the top of the mobile vehicle.

[0031] It should be noted that the particulate matter lidar body 100 involved in this utility model is prior art, so it will not be described in detail in this application. The core improvement of this utility model lies in the structural design of the assembly frame 200, in order to solve the technical problems existing in the prior art.

[0032] Furthermore, it also includes two flange structures 260 respectively welded to the inner sides of the two clamping seats 250, and a tie rod 270 is installed through the two flange structures 260.

[0033] Furthermore, both ends of the T-shaped slide seat 210 are fitted with plugs 2110.

[0034] Furthermore, the bottom of both spring dampers 230 is covered with a rubber-insulated anti-slip pad 2310.

[0035] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
