[0036] Please also read Figures 1 to 4 Now, the mobile vehicle chassis inspection device 100 provided in the embodiment of the present application is described. The mobile vehicle chassis inspection device 100 comprises: a lane 10, a safety island 20, a guide rail 30 and a scanning vehicle 40.

[0037] Specifically, the safety island 20 is located on one side of the lane 10, a passage 21 is provided in the safety island 20, the guide rail 30 includes an inner rail 31 and an outer rail 32, the inner rail 31 is located in the passage 21, the outer rail 32 is located on the lane 10, and the inner rail 31 and the outer rail 32 are connected end to end, the scanning vehicle 40 is slidably set on the guide rail 30, and a camera 41 is provided on the scanning vehicle 40.

[0038] When there is no vehicle in the lane 10, the scanning vehicle 40 can be hidden in the passage 21 of the safety island 20. On the one hand, it can prevent the scanning vehicle 40 from being exposed to the sun or rain, thereby increasing the service life of the scanning vehicle 40. On the other hand, it can prevent the camera 41 from accumulating dust, thereby ensuring the clarity of the image quality.

[0039] When the truck enters the lane 10, the outer rail 32 is just below the chassis of the truck. The scanning vehicle 40 located in the passage 21 moves along the inner rail 31, exits the passage 21 and enters the outer rail 32. The scanning vehicle 40 continues to move and can pass under the chassis of the truck under the guidance of the outer rail 32. At the same time, the camera 41 is turned on to obtain the chassis image of the truck. The backstage staff receives the chassis image of the truck through the computer host and checks it to determine whether to release it.

[0040] Compared with the prior art, the mobile vehicle chassis inspection device 100 provided in the present application provides a channel 21 in the safety island 20, so that the scanning vehicle 40 can be hidden in the channel 21, which not only reduces the installation space requirement but also protects the scanning vehicle 40; the guide rail 30 is provided to guide the scanning vehicle 40, so that the scanning vehicle 40 can move along a fixed track, which not only improves the stability of the shooting picture, but also improves the efficiency of vehicle chassis inspection and reduces labor costs.

[0041] In another embodiment of the present application, please refer to Figure 5 The scanning vehicle 40 is provided with a fill light 44 .

[0042] It is understandable that the insufficient lighting under the chassis of the truck may affect the quality of the picture taken by the camera 41, and the chassis of the truck can be illuminated by the fill light 44. Therefore, whether it is night or day, the fill light 44 can ensure the clarity of the picture taken and improve the inspection accuracy.

[0043] In another embodiment of the present application, please refer to Figure 5 The scanning vehicle 40 is provided with a plurality of rollers 42 and brushes 43 , and the brushes 43 and the rollers 42 are in contact with the guide rail 30 respectively, so that the scanning vehicle 40 performs power carrier communication through the guide rail 30 .

[0044] It is understandable that the scanning vehicle 40 can transmit the image and video information acquired by the camera 41 to the computer host of the backstage staff in real time by performing power carrier communication through the guide rail 30. The backstage staff can check the chassis image of the truck after receiving it through the computer host to determine whether to release it. At the same time, the guide rail 30 can also provide power to the scanning vehicle 40 in real time, thereby improving the endurance of the scanning vehicle 40.

[0045] In another embodiment of the present application, the camera 41 includes at least one fisheye camera.

[0046] It is understandable that the fisheye camera can independently realize a panoramic camera with wide-range and no blind spot monitoring, and the monitoring range can reach 180 degrees. The image captured by the camera 41 is corrected and the image is expanded by the image processing technology of the internal main chip, and the spherical image is converted into a normal plane view suitable for the human eye. The number of the fisheye cameras can be set to multiple, for example, multiple fisheye cameras are processed in parallel, and a complete and clear image is formed through image synthesis technology.

[0047] In another embodiment of the present application, please refer to Figure 3 and Figure 4 An automatic cleaning mechanism is provided in the channel 21 , and the automatic cleaning mechanism includes a fan 22 .

[0048] It is understandable that the automatic cleaning mechanism can clean dust or moisture from the scanning vehicle 40 through the fan 22. For example, when the scanning vehicle 40 returns to the passage 21 after a round of vehicle chassis inspection, the fan 22 is turned on to clean the scanning vehicle 40 on the inner rail 31, and at the same time, the air in the passage 21 flows to keep the passage 21 dry.

[0049] In another embodiment of the present application, please refer to Figure 3 and Figure 4 The entrance and exit of the passage 21 are respectively provided with automatic doors 23, and the automatic door 23 includes a sealing plate 231 and a driving mechanism 232. The sealing plate 231 is arranged at the output end of the driving mechanism 232, so that the automatic door 23 can automatically open or close the entrance and exit of the passage 21.

[0050] It can be understood that when there is no vehicle in the lane 10, the scanning vehicle 40 can be hidden in the passage 21 of the safety island 20, and the automatic door 23 can keep the entrance and exit of the passage 21 closed to prevent foreign objects such as dust, rain, and insects from entering the passage 21, so as to increase the service life of components in the passage 21.

[0051] In another embodiment of the present application, please refer to Figure 1 and Figure 2 The mobile vehicle chassis inspection device 100 also includes an entrance gate 50 and an exit gate 60 , and the outer rail 32 is located between the entrance gate 50 and the exit gate 60 .

[0052] It is understandable that after the entrance gate 50 is opened, the truck can enter the detection area and stop. After the entrance gate 50 is closed, the scanning vehicle 40 can start to check the truck chassis. If the inspection passes, the exit gate 60 is opened to release the truck. If the inspection fails, the alarm sounds and the staff further checks the truck. This can prevent the following vehicles from following the truck and prevent the truck from escaping.

[0053] In another embodiment of the present application, please refer to Figure 1 and Figure 2 The mobile vehicle chassis inspection device 100 also includes a ground sensing device 70 , and the ground sensing device 70 is arranged on the lane 10 between the entrance gate 50 and the exit gate 60 .

[0054] It is understandable that when a truck enters the detection area, the position of the truck can be sensed by the ground sensing device 70 so that the scanning vehicle 40 can automatically inspect the truck.

[0055] In another embodiment of the present application, please refer to Figure 1 and Figure 2 The mobile vehicle chassis inspection device 100 also includes an infrared radiation device 80 , and the infrared radiation device 80 is installed on both sides of the lane 10 .

[0056] It is understandable that the infrared radiation device 80 includes an infrared transmitter and an infrared receiver, and the infrared transmitter and the infrared receiver are respectively located on both sides of the lane 10. If a vehicle passes through the lane 10, it will block the infrared receiver from receiving the signal. Therefore, the infrared radiation device 80 can further sense the position of the truck to prevent the gate from hitting the truck.
