Description

Technical Field

[0001] This utility model relates to the technical field of road quality testing equipment, and more specifically, to a modular integrated cabin-type road damage detection vehicle. Background Technology

[0002] With my country's economic development, more and more areas are paving cement roads to form highways. However, due to the passage of various vehicles and natural disasters, the road surface is easily damaged. Therefore, comprehensive road inspection is particularly important.

[0003] When a road condition detection vehicle fails to brake in time and rear-ends another vehicle, the road damage detection device, which is located at the front of the vehicle, is easily damaged in the event of a rear-end collision, resulting in a shorter service life for the device.

[0004] A search revealed that Chinese patent CN214530088U discloses a multi-functional road surface inspection vehicle. By setting up an area array camera, which is located at the upper part of the rear of the vehicle, vehicles approaching from behind will not brake in time and will collide with the lower part of the rear of the vehicle, thereby reducing the damage to the area array camera caused by vehicles approaching from behind or in front. This has the advantage of increasing the service life of the road surface damage detection device.

[0005] However, in actual use, when the aforementioned multi-functional road inspection vehicle is not in operation, there are unavoidable assembly gaps or deformation gaps at the connection between the cabinet door and the cabin. This allows dust and rainwater from the road to easily enter the cabin through these gaps, which can affect the electrical components inside the cabin. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides a modular integrated cabin-type road damage detection vehicle to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A modular integrated cabin-type road damage detection vehicle includes a detection vehicle body and a fixed plate fixedly connected to the top of the detection vehicle body. A cabin is installed on the top of the fixed plate. A fixed frame is fixedly connected inside the cabin. A laser radar and a camera are installed on the front side of the fixed frame. Two integrated servers are fixedly connected to the front side of the fixed frame. Protective components are installed on the cabin. The protective assembly includes two electro-hydraulic rods hinged to the front of the cabin, with a cabinet door hinged to one end of each electro-hydraulic rod. An air pump for inflation is fixedly connected to one side of the fixed frame. A connecting pipe is fixedly connected to the output end of the air pump. An inflation solenoid valve is installed on the connecting pipe. A sealing airbag strip is connected to one end of the connecting pipe. The cabin is equipped with a flow guiding mechanism. The sealing airbag strip is installed inside the cabin. One side of the sealing airbag strip is connected to a vent pipe, and a vent solenoid valve is installed on the vent pipe. A groove is formed on one side of the sealing airbag strip. A protective protrusion that matches the groove is fixedly connected to one side of the cabinet door for cooperation with the sealing airbag strip to form a seal. Sealing strips for sealing are fixedly connected to both the cabin and the cabinet door. The two sealing strips are aligned. Sealing grooves are formed on both sides of the cabinet door for fitting the sealing airbag strip. A rotating shaft is fixedly connected inside the cabinet door, and both ends of the rotating shaft are rotatably connected to the inside of the cabin.

[0008] As a further description of the above technical solution: the airflow guiding mechanism includes a cross-section on one side of the cabin body with an arc-shaped edge for guiding airflow. Both sides of the cabin body are fixedly connected to airflow guide plates, and multiple airflow guide blades with arc-shaped ends are fixedly connected to the airflow guide plates. The multiple airflow guide blades are symmetrically distributed on the cabinet door, and the airflow guide plates are teardrop-shaped.

[0009] The technical effects and advantages of this utility model are as follows: 1. By setting up protective components, compared with existing technologies, the airbag strip can be inflated and extended into the sealing groove on the cabinet door, and cooperate with the protective protrusion to form an active sealing protection. This can effectively compensate for the gap at the connection between the cabinet door and the cabin, forming a tight sealing channel. Moreover, the two sealing strips correspond to each other to form a secondary sealing protection, which greatly enhances the sealing effect, thus protecting the cabin equipment from contamination and damage when not in use. 2. By setting up a flow guiding mechanism, compared with the existing technology, the cross-section on the cabin and the two teardrop-shaped flow guides can reasonably guide and divert the oncoming airflow during driving. At the same time, multiple flow guides allow the airflow to flow smoothly along the curved surface across both sides of the cabin, avoiding turbulence and eddies on the cabin surface, which helps to reduce the vehicle's swaying and shaking in crosswind environments.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Example 1: The embodiments disclosed in this application are as follows: Figure 1-9 The modular integrated cabin-type road damage detection vehicle shown includes a detection vehicle body 1 and a fixing plate 2 fixedly connected to the top of the detection vehicle body 1. A cabin 3 is installed on the top of the fixing plate 2. A fixing frame 4 is fixedly connected inside the cabin 3. A laser radar 5 and a camera 6 are set on the front side of the fixing frame 4. Two integrated servers 7 are fixedly connected to the front side of the fixing frame 4. Protective components are installed on the cabin 3. The protective assembly includes two electro-hydraulic rods 8 hinged to the front of the cabin 3, with a cabinet door 9 hinged to one end of each electro-hydraulic rod 8. A pump 10 for inflation is fixedly connected to one side of the fixed frame 4. A connecting pipe 11 is fixedly connected to the output end of the pump 10. An inflation solenoid valve 12 is installed on the connecting pipe 11. A sealing airbag strip 13 is connected to one end of the connecting pipe 11. A flow guiding mechanism is installed on the cabin 3. The sealing airbag strip 13 is installed inside the cabin 3. One side of the sealing airbag strip 13 is connected to a vent pipe 14. A vent solenoid valve 15 is installed on the vent pipe 14. A groove is opened on one side of the sealing airbag strip 13. A protective protrusion 16 that matches the groove is fixedly connected to one side of the cabinet door 9. It is used to cooperate with the sealing airbag strip 13 to form a seal. Sealing strips 21 for sealing are fixedly connected to both the cabin 3 and the cabinet door 9. The two sealing strips 21 are corresponding to each other. Sealing grooves 17 are opened on both sides of the cabinet door 9 to fit the sealing airbag strip 13. A rotating shaft 18 is fixedly connected inside the cabinet door 9. The two ends of the rotating shaft 18 are rotatably connected to the inside of the cabin 3.

[0022] It is worth noting that the sealing airbag strip 13 is made of neoprene rubber, and the sealing strip 21 is made of silicone. This embodiment also includes a corresponding controller, which can be a PLC controller used to coordinate and drive structures such as the lidar 5, camera 6, integrated server 7, electric hydraulic rod 8, air pump 10, inflation solenoid valve 12 and deflation solenoid valve 15. This is existing technology and can be set according to actual needs, so it will not be described in detail and is not shown in the accompanying drawings.

[0023] The implementation principle of this embodiment is as follows: Two electro-hydraulic rods 8 are simultaneously activated by an external control device. The two ends of the electro-hydraulic rods 8 are hinged to the cabin 3 and the cabinet door 9, respectively, so that the two electro-hydraulic rods 8 can push the cabinet door 9 to flip. The rotating shaft 18 is rotatably connected to the cabin 3, which can provide support for the flipping of the cabinet door 9. After the cabinet door 9 flips, the lidar 5 and the camera 6 are exposed directly above the road surface. Subsequently, the controller synchronously activates the lidar 5 and the camera 6. The lidar 5 can acquire the three-dimensional geometric information of the road surface by emitting a laser beam and receiving the reflected signal. The camera 6 synchronously acquires high-definition images of the road surface. The data acquired by both are transmitted to the integrated server 7 in real time. The integrated server 7 fuses and analyzes the two types of data to determine the type of road surface damage and uploads the results to the cloud for subsequent road surface detection. When not in use, close cabinet door 9 so that it fits snugly against the cabin 3. Cabinet door 9 allows the protective protrusion 16 to insert into the groove on one side of the sealing airbag strip 13. Simultaneously, cabinet door 9 allows the sealing strip 21 on cabinet door 9 to align with the sealing strip 21 on cabin 3, providing a seal at the connection between cabinet door 9 and cabin 3. Then, start air pump 10. Air pump 10 fills the sealing airbag strip 13 with gas through connecting pipe 11, ensuring that the sealing airbag strip 13 can maintain its seal after cabinet door 9 is connected to cabin 3. When the airbag expands, the protective protrusion 16 is inserted into the groove of the sealing airbag strip 13. After the sealing airbag strip 13 expands, it can fit tightly with the protective protrusion 16 to form a labyrinth seal. After inflation, it extends into the sealing grooves 17 on both sides of the cabinet door 9. The expansion of the sealing airbag strip 13 after inflation can effectively and actively compensate for the gap between the cabinet door 9 and the cabin 3. It can also form a multi-level sealing protection with the two sealing strips 21 to prevent external dust, moisture and other impurities from entering the cabin 3, protect the electronic components of the cabin 3 from contamination and damage, and ensure the normal operation of the equipment.

[0024] Example 2: Based on Embodiment 1, this embodiment discloses a modular integrated cabin-type road damage detection vehicle, referring to... Figure 8 As shown, the flow guiding mechanism has a flow guiding section on one side of the cabin 3. The edge of the section is arc-shaped and used to guide the airflow. Both sides of the cabin 3 are fixedly connected to the flow guiding plate 19. Multiple flow guiding blades 20 with arc-shaped ends are fixedly connected to the flow guiding plate 19. The multiple flow guiding blades 20 are symmetrically distributed on the flow guiding plate 19. The flow guiding plate 19 is teardrop-shaped. The implementation principle of this embodiment is as follows: When the vehicle body 1 drives the cabin 3 in motion, the cross-section and edge arc of one side of the cabin 3 can guide the airflow to flow upward along the cross-section. At the same time, the teardrop-shaped cabinet doors 9 located on both sides of the cabin 3 can divert the oncoming airflow. Meanwhile, multiple guide vanes 20 can provide a flow path for the diverted airflow, allowing the airflow to flow smoothly along the arc surface across both sides of the cabin 3, reducing the friction and collision between the air and the cabin, reducing the impact force on the cabin surface caused by airflow turbulence, and preventing the air from affecting the detection.
