Description

Technical Field

[0001] This utility model relates to the field of machine vision technology, and in particular to a vehicle undercarriage inspection device. Background Technology

[0002] To conduct safety checks on passing vehicles on the road, undercarriage inspection equipment is usually installed on the road surface.

[0003] In existing technologies, vehicle undercarriage inspection equipment generally includes handheld inspection devices, road surface-fixed vehicle undercarriage inspection devices, and vehicles embedded in the road. Handheld inspection devices generally require manual handling, which is time-consuming, labor-intensive, and inefficient. Road surface-fixed vehicle undercarriage inspection devices are usually fully exposed above the road surface and are quite tall, making them unsuitable for inspecting the undercarriages of both high-chassis and low-chassis vehicles, thus limiting their application range. While embedded vehicle undercarriage inspection devices are suitable for inspecting the undercarriages of both low-chassis and high-chassis vehicles, the camera glass dome of embedded equipment is prone to accumulating dust and snow, affecting the inspection results. Regular manual cleaning and maintenance of the glass dome surface is also required, resulting in high maintenance costs. Utility Model Content

[0081] 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 based on this application are within the protection scope of the present utility model.

[0082] To address the issue of high maintenance costs for undercarriage inspection equipment in related technologies, this application provides an undercarriage inspection device, which will be described in detail below.

[0083] See Figures 1a to 1d ,in, Figure 1a This is a schematic diagram of the overall structure of the vehicle undercarriage inspection equipment provided in the embodiments of this application; Figure 1b for Figure 1a A cross-sectional view of the undercarriage inspection equipment shown in Figure AA; Figure 1c for Figure 1a The BB cross-sectional view of the undercarriage inspection equipment shown; Figure 1d for Figure 1a The diagram shows an exploded view of the undercarriage inspection equipment.

[0084] like Figures 1a to 1dAs shown, the vehicle undercarriage detection device provided in this application embodiment includes a base shell 100 buried in the ground, and at least one main light source assembly 200, a camera assembly 300, an air blowing assembly 400 and at least two anti-collision strips 500 installed on the base shell 100.

[0085] The bottom shell 100 has a bottom shell receiving space 130 formed by extending downward from the top;

[0086] Each main light source assembly 200 includes: a main light source body 220; the main light source body 220 is installed within the undercarriage receiving space 130 to illuminate the underside of the vehicle;

[0087] Camera assembly 300 includes: camera body 320; camera body 320 is installed in bottom housing accommodating space 130, lens cover 321 on top of camera body 320 is located on top of bottom housing 100, camera body 320 takes pictures of the underside of vehicle through lens cover 321;

[0088] The blowing assembly 400 includes: at least one blowing head 420, which is detachably mounted on the top of the camera assembly 300 adjacent to the lens cover 321, for blowing the lens cover 321;

[0089] At least two anti-collision strips 500 are parallel and spaced apart from the top of the bottom shell 100, and the inner sides of the at least two anti-collision strips 500 can cover each blow head 420.

[0090] This utility model provides a vehicle undercarriage inspection device, including a base shell 100 buried in the ground, and at least one main light source assembly 200, a camera assembly 300, an air blowing assembly 400, and at least two anti-collision strips 500 installed on the base shell 100. The base shell 100 is buried in the ground and can be used to inspect the undercarriages of both high-chassis and low-chassis vehicles, with a wide range of applications. The air blowing assembly 400 includes at least one blowing head 420, which is used to blow the lens cover 321 to clean the dust and snow accumulated on the surface of the camera lens cover 321, eliminating the need for manual cleaning and maintenance of the camera lens cover 321 surface periodically, thus reducing maintenance costs.

[0091] If an air passage is incorporated within the camera assembly or other structure for the purge head to blow air, the machining of the camera assembly or other structure becomes significantly more difficult, greatly increasing manufacturing costs. Furthermore, it hinders subsequent maintenance; if the air passage becomes blocked during use, all related structural components must be disassembled for inspection and repair, making maintenance extremely difficult.

[0092] This application detachably mounts the blow head 420 to the top of the camera assembly 300, greatly reducing the processing difficulty and manufacturing cost of the camera assembly. It also makes later maintenance more convenient; if the blow head becomes clogged during use, only the blow head needs to be replaced, minimizing maintenance difficulty.

[0093] like Figure 1d As shown, the bottom shell 100 includes a top plate 110 and a lower shell 120 extending downward from the top plate 110; the top plate 110 is provided with a main light source mounting opening 111 and a camera mounting opening 112; each main light source assembly 200 is mounted on the bottom shell 100 through a main light source mounting opening 111; the camera assembly 300 is mounted on the bottom shell 100 through the camera mounting opening 112; the lower shell 120 and the top plate 110 form a bottom shell receiving space 130.

[0094] like Figure 1d As shown, each main light source assembly 200 also includes: a main light source mounting base 210; the main light source mounting base 210 is fixed to the top of the main light source body 220, the main light source mounting base 210 is mounted on the top plate 110 of the bottom shell 100 through a main light source mounting opening 111, the light-emitting device of the main light source body 220 is mounted inside the main light source body 220, and the main light source body 220 is mounted in the bottom shell receiving space 130 through the main light source mounting base 210 so as to illuminate the underside of the vehicle through the main light source mounting opening 111;

[0095] The camera assembly 300 also includes: a camera housing 310; the camera housing 310 is fixed to the top of the camera body 320, and the camera housing 310 is mounted on the top plate 110 of the bottom shell 100 through the camera mounting opening 112; the lens cover 321 on the top of the camera body 320 is located on the top of the camera housing 310 to take pictures of the underside of the vehicle through the camera mounting opening 112; the camera body 320 is mounted in the bottom shell receiving space 130 through the camera housing 310.

[0096] like Figure 1c and Figure 1d As shown in the embodiment of this application, the undercarriage inspection device may further include: an auxiliary light source assembly 600;

[0097] The number of main light source components 200 can be two; the number of main light source mounting openings 111 can be two; the top plate 110 is also provided with a secondary light source mounting opening 116;

[0098] Two main light source mounting openings 111 are located at both ends of the top plate 110 along the length of the top plate 110, and the auxiliary light source mounting opening 116 and the camera mounting opening 112 are located between the two main light source mounting openings 111.

[0099] The secondary light source assembly 600 includes: a secondary light source mounting base 610 and a secondary light source body 620;

[0100] The auxiliary light source mounting base 610 is mounted on the top plate 110 of the bottom shell 100 through the auxiliary light source mounting opening 116. The light-emitting device of the auxiliary light source body 620 is installed inside the auxiliary light source body 620 so as to illuminate the underside of the vehicle through the auxiliary light source mounting opening 116. The auxiliary light source body 620 is located in the bottom shell accommodating space 130, and the light-emitting device of the auxiliary light source body 620 is set at an angle.

[0101] Specifically, the camera mounting opening 112 is located between the secondary light source mounting opening 116 and the main light source mounting opening 111; the secondary light source body 620 has an overall shape of a trapezoid with a sloping side 6231, and the light-emitting device of the secondary light source body 620 is placed along the sloping side 6231.

[0102] In this embodiment, the light-emitting device of the secondary light source body 620 in the secondary light source assembly 600 is placed along the inclined surface 6231, so that the light-emitting device emits light in the direction of the camera assembly, thereby further supplementing the light for the camera assembly and improving the clarity of the captured image.

[0103] like Figure 1a and Figure 1d As shown, at least two anti-collision strips 500 are arranged in parallel at intervals on the top plate 110 of the bottom shell 100, and the tops of the two anti-collision strips 500 are higher than the main light source mounting base 210 and the camera upper shell 310; and the main light source mounting base 210 and the camera upper shell 310 are located in the interval area between the two anti-collision strips 500.

[0104] In this embodiment, the tops of the two anti-collision strips 500 are higher than the main light source mounting base 210 and the camera housing 310. The main light source mounting base 210 and the camera housing 310 are located in the gap area between the two anti-collision strips 500, so that the anti-collision strips can cover part of the main light source mounting base and the camera housing, and the main light source assembly can illuminate the underside of the vehicle through the gap area between the two anti-collision strips, and the camera assembly can photograph the underside of the vehicle through the gap area between the two anti-collision strips.

[0105] like Figure 1a and Figure 1d As shown, each anti-collision strip 500 includes three anti-collision blocks, namely two first anti-collision blocks 510 and one second anti-collision block 520;

[0106] Two first anti-collision blocks 510 are respectively disposed at both ends of the top plate 110 along the length direction of the top plate 110, and a second anti-collision block 520 is disposed between the two first anti-collision blocks 510. The top of each anti-collision block is higher than the main light source mounting base 210, the auxiliary light source mounting base 610 and the camera upper housing 310, and the top of each anti-collision block is flush with it. The second anti-collision block 520 of at least two anti-collision strips 500 faces the side of the camera upper housing 310 and can cover each of the blow heads 420 disposed on the top of the camera upper housing 310.

[0107] The second anti-collision block 520 of each anti-collision strip 500 contacts the two first anti-collision blocks 510 at both ends along the length of the bottom shell 100.

[0108] like Figure 1a As shown, since the undercarriage detection equipment is buried in the ground, it is generally necessary to dig a pit in the ground and then put the undercarriage detection equipment into the pit. Therefore, the corner of the first anti-collision block 510 away from the camera assembly 300 is fixedly connected with a hanging ring 513. When putting the undercarriage detection equipment into the pit or taking it out of the pit, a detachable chain can be connected to the hanging ring 513. The undercarriage detection equipment can be put into the pit or taken out of the pit through the chain, making the installation and removal of the undercarriage detection equipment more convenient.

[0109] See Figure 1e , Figure 1e for Figure 1b Enlarged view of point C; as shown Figure 1e As shown, the bottom of the camera assembly 300 is provided with camera thermal conductive foam 340. The bottom of the camera thermal conductive foam 340 is in contact with the bottom of the bottom shell 100. The camera thermal conductive foam 340 can conduct the heat generated by the camera assembly 300 to the bottom of the bottom shell 100 for heat dissipation and prevent the camera assembly from being damaged due to excessive temperature.

[0110] like Figure 1a and Figure 1b As shown, the bottom shell 100 is provided with a first through hole 140 for the main cable, through which the main cable 800 passes and connects to an external power source.

[0111] See Figure 2a and Figure 2b , Figure 2a for Figure 1a The diagram shows the structure of the undercarriage inspection equipment after the gas pipeline is installed (the main cable and some anti-collision blocks are not shown). Figure 2b for Figure 2a A top view of the vehicle undercarriage inspection equipment shown.

[0112] like Figure 2a and Figure 2b As shown, the blowing assembly 400 also includes: a gas conduit 410; at least one blow head 420 is disposed on the top of the camera housing 310, and the gas conduit 410 is used to deliver gas supplied by an external gas source to the blow head 420.

[0113] Specifically, the gas pipeline 410 is fixedly connected to the top of the top plate 110 of the bottom shell 100.

[0114] If the gas pipeline is placed at the bottom of the vehicle under-inspection equipment, the arrangement of the gas pipeline must be carefully considered during installation. It is easy to crush the gas pipeline during installation, making it impossible for the gas pipeline to blow air normally.

[0115] In this application, the gas pipe 410 is fixedly connected to the top of the top plate 110 of the bottom shell 100, which reduces the risk of the gas pipe being crushed during installation, making it impossible for the gas pipe to blow air normally.

[0116] In this embodiment, at least one blow head 420 includes: a connecting part and a blow port; the connecting part is threadedly connected to the upper housing of the camera, and the connecting part and the upper housing of the camera are sealed by a sealing ring.

[0117] In this embodiment, the connecting part is threaded to the camera housing, reducing assembly difficulty and the number of parts. Furthermore, the connecting part can be manually rotated, allowing it to rotate at a certain angle relative to the camera housing. Compared to methods where the air outlet is mounted on other structural components instead of the camera assembly, the blowing direction and angle of the blowing head in this application are flexibly adjustable. Only manual rotation of the connecting part is required; no modification to the camera assembly is necessary.

[0118] In some embodiments, the blowing direction can also be changed by replacing the blowing head with one facing a different direction.

[0119] In this embodiment, the connection part is sealed with the camera upper shell by a sealing ring. When the blow head is tightened onto the camera upper shell, the sealing ring is also compressed, so dust will not enter between the blow head and the camera upper shell, making it less likely for dust to accumulate at the connection between the blow head and the camera upper shell, thus reducing the probability of affecting the blowing function.

[0120] In some embodiments, the blowing nozzle of the blower head blows air periodically, so dust is not easily allowed to enter the blowing nozzle of the blower head.

[0121] like Figure 2a and Figure 2b As shown, there are two blow heads 420, which are respectively disposed on the top of the camera housing 310, located symmetrically on both sides of the periphery of the lens cover 321. In other embodiments, there may be multiple blow heads 420 evenly arranged around the lens cover 321 to blow the lens cover 321.

[0122] The air blowing assembly 400 also includes: a pneumatic multi-opening connector 430; the pneumatic multi-opening connector 430 is installed on the top plate 110 and is located between the bottom of the anti-collision strip 500 and the top plate 110;

[0123] The gas pipeline 410 includes: a main gas pipe 411 and at least two branch gas pipes 412, each branch gas pipe 412 being connected to a purge head 420; a pneumatic multi-opening connector 430 is disposed at the connection between the main gas pipe 411 and the at least two branch gas pipes 412, for distributing the gas delivered by the main gas pipe 411 to the at least two branch gas pipes 412 respectively; the main gas pipe 411 is used to deliver gas delivered by an external gas source to the pneumatic multi-opening connector 430.

[0124] The top of the top plate 110 is also provided with a pneumatic adapter 150 and an air pipe fixing threaded hole. The pneumatic adapter 150 is used to connect an external air pipe to the surface of the top plate 110. The air pipe on the surface of the top plate 110 is fixed in the air pipe fixing threaded hole by screws.

[0125] Specifically, the blow head 420 can be fixed to the top of the camera housing 310 with screws, and the pneumatic multi-opening connector 430 can be fixed to the top plate 110 of the bottom housing 100 with screws. The gas generated by the air pump enters at least two branch air pipes 412 through the pneumatic multi-opening connector 430 along the main air pipe 411.

[0126] The pneumatic multi-port connector 430 is detachably connected to the main air pipe 411 and at least two branch air pipes 412, which makes it easier to maintain or replace the main air pipe 411 and at least two branch air pipes 412.

[0127] Specifically, in this embodiment, the purge head 420 is divided into a first purge head 421 and a second purge head 422. The pneumatic multi-port connector 430 converts the main air pipe 411 into two branch air pipes 412, namely the first branch air pipe 4121 and the second branch air pipe 4122, thereby realizing the diversion of the gas input in the main air pipe 411. The first branch air pipe 4121 is connected to the first purge head 421, and the second branch air pipe 4122 is connected to the second purge head 422.

[0128] like Figure 2a and Figure 2b As shown, the air blowing assembly 400 also includes two air blowing adapters 440;

[0129] Two air-blowing adapters 440 are respectively fixed on the two sides of the camera housing 310 at positions corresponding to the blow head 420;

[0130] The input end of the air-blowing adapter 440 is connected to the air distribution pipe 412, and the output end of the air-blowing adapter 440 is connected to the purge head 420; the air-blowing adapter 440 is used to deliver the gas in the air distribution pipe 412 to the purge head 420.

[0131] Specifically, the two air-blowing adapters 440 are the first air-blowing adapter 441 and the second air-blowing adapter 442, respectively. The camera upper housing 310 includes a first side 311 and a second side 312. The first air-blowing adapter 441 is fixed on the first side 311 of the camera upper housing 310 at a position corresponding to the first blow-blowing head 421. The second air-blowing adapter 442 is fixed on the second side 312 of the camera upper housing 310 at a position corresponding to the second blow-blowing head 422. The first air distribution pipe 4121 is connected to the first blow-blowing head 421 through the first air-blowing adapter 441, and the second air distribution pipe 4122 is connected to the second blow-blowing head 422 through the second air-blowing adapter 442.

[0132] The vehicle undercarriage inspection device provided in this embodiment is buried in the ground to inspect the undercarriage of vehicles passing over it for hazardous materials. The vehicle undercarriage inspection device can reach an IP68 sealing rating.

[0133] Specifically, the bottom shell 100 can be a one-piece welded component, and can be made of stainless steel, such as... Figure 2a As shown, the top plate 110 is also provided with an air pipe fixing buckle 118, and the gas pipeline 410 can be fixed to the top plate 110 through the air pipe fixing buckle 118.

[0134] The main light source assembly 200 and the camera assembly 300 can be fixedly connected to the base shell 100 by screws; the external air source can be an air pump, which generates gas and delivers the gas to the purge head 420 through the gas pipeline 410.

[0135] See Figure 3 , Figure 3 for Figure 1a The diagram shows the structural design of the bottom shell of the undercarriage inspection equipment; as shown. Figure 3 As shown, the main light source mounting opening 111 of the top plate 110 is surrounded by a main light source external sealing groove 113, and a main light source external sealing ring 1131 is provided in the main light source external sealing groove 113. The main light source external sealing ring 1131 is pressed and fixed in the main light source external sealing groove 113 by the bottom of the top plate 110 and the main light source mounting base 210.

[0136] The external sealing ring 1131 of the main light source improves the sealing performance between the main light source assembly 200 and the base shell 100, preventing moisture or dust from entering the base shell and avoiding corrosion or contamination of the internal components. The external sealing groove 113 of the main light source is an IP68 rated sealing groove.

[0137] like Figure 3 As shown, the camera mounting opening 112 of the top plate 110 is surrounded by an external camera sealing groove 114, and an external camera sealing ring 1141 is provided in the external camera sealing groove 114. The external camera sealing ring 1141 is pressed and fixed in the external camera sealing groove 114 by the top plate 110 and the bottom of the camera upper shell 310.

[0138] The external camera sealing ring 1141 improves the sealing performance between the camera assembly 300 and the base housing 100, preventing moisture or dust from entering the base housing and avoiding corrosion or contamination of the internal components. The external camera sealing groove 114 is an IP68 rated sealing groove.

[0139] like Figure 3 As shown, the auxiliary light source mounting opening 116 of the top plate 110 is surrounded by an auxiliary light source external sealing groove 117, and an auxiliary light source external sealing ring 1171 is provided in the auxiliary light source external sealing groove 117. The auxiliary light source external sealing ring 1171 is pressed and fixed in the auxiliary light source external sealing groove 117 by the top plate 110 and the auxiliary light source mounting base 610.

[0140] The external sealing ring 1171 of the auxiliary light source improves the sealing performance between the auxiliary light source assembly 600 and the base shell 100, preventing moisture or dust from entering the base shell and avoiding corrosion or contamination of the internal components. The external sealing groove 117 of the auxiliary light source is an IP68 rated sealing groove.

[0141] In addition, such as Figure 3 As shown, a first airtightness test nut 115 is provided on the top plate 110 of the bottom shell 100 to verify the airtightness performance of the bottom shell 100 and ensure the sealing of the bottom shell.

[0142] like Figure 3 As shown, the main cable 800 is sequentially fitted with an airtight nut 810, a steel pipe 820, and a gland 830.

[0143] Among them, the airtight nut 810 is fitted at the first through hole 140 of the main cable on the outside of the bottom shell 100 to ensure the airtightness of the bottom shell, prevent moisture from entering the bottom shell, and avoid corrosion of the various components inside the bottom shell.

[0144] The steel pipe 820 is sleeved on the outside of the airtight nut 810 to protect the main cable 800 from mechanical damage and to further ensure the airtightness of the bottom shell.

[0145] The gland 830 is fixed to the end of the steel pipe 820 on the main cable 800 away from the airtight nut 810. The gland 830 locks the steel pipe 820 on the main cable 800 to prevent the steel pipe 820 from moving or falling off.

[0146] The main cable 800 enters the interior of the bottom housing 100 through the gland 830, steel pipe 820 and airtight nut 810.

[0147] See Figure 4a and Figure 4b , Figure 4a for Figure 1a A schematic diagram of the camera assembly of the undercarriage inspection device shown. Figure 4b for Figure 4a An exploded view of the camera assembly of the undercarriage inspection equipment shown; as follows: Figure 4a and Figure 4b As shown, ventilation holes 313 are provided on two sides of the camera housing 310 at positions corresponding to the air-blowing adapter 440. The input end of the ventilation hole 313 is connected to the output end of the air-blowing adapter 440, and the output end of the ventilation hole 313 is connected to the purge head 420. The ventilation hole 313 connects the air-blowing adapter 440 and the purge head 420, and is used to deliver the gas from the air-blowing adapter 440 to the purge head 420.

[0148] Specifically, the vent 313 includes a first vent and a second vent. The first vent is located at the position corresponding to the first side 311 of the camera upper housing 310 and the first air blower adapter 441, and the second vent is located at the position corresponding to the second side 312 of the camera upper housing 310 and the second air blower adapter 442.

[0149] The input end of the first vent is connected to the output end of the first air-blowing adapter 441, and the output end of the first vent is connected to the first purge head 421. The first vent connects the first air-blowing adapter 441 and the first purge head 421, and is used to deliver the gas from the first air-blowing adapter 441 to the first purge head 421.

[0150] The input end of the second vent is connected to the output end of the second air-blowing adapter 442, and the output end of the second vent is connected to the second purge head 422. The second vent connects the second air-blowing adapter 442 and the second purge head 422, and is used to deliver the gas from the second air-blowing adapter 442 to the second purge head 422.

[0151] The gas delivery path is as follows: gas is generated by an air pump and delivered to a pneumatic multi-port connector 430 via a main air pipe 411. The pneumatic multi-port connector 430 then delivers the gas to a first branch air pipe 4121 and a second branch air pipe 4122. The first branch air pipe 4121 delivers the gas sequentially through a first air-blowing adapter 441 and a first vent to a first purge head 421. The second branch air pipe 4122 delivers the gas sequentially through a second air-blowing adapter 442 and a second vent to a second purge head 422. This achieves the delivery of gas generated by an external air source to the purge head 420, allowing the gas to purge the lens cover 321.

[0156] like Figure 4b As shown, the camera housing 322 is also provided with a second airtightness test screw 327, which is used to test the airtightness of the camera components.

[0157] See Figure 5a and Figure 5b , Figure 5a for Figure 1a A schematic diagram of the main light source assembly of the vehicle under-surface inspection equipment shown. Figure 5b for Figure 5a An exploded view of the main light source component is shown below; as shown Figure 5a and Figure 5b As shown, the main light source mounting base 210 includes a main light source mounting base upper cover 211 and a main light source mounting base lower plate 212, which can be fixedly connected by screws.

The bottom of the main light source heat-conducting sheet metal 250 is connected to the main light source heat-conducting foam 251, which is in contact with the bottom of the bottom housing 100.

[0160] The main light source heat-conducting sheet metal 250 and the main light source heat-conducting foam 251 can conduct the heat generated by the main light source lamp board 221 to the bottom of the bottom shell 100 for heat dissipation and prevent the main light source assembly from being damaged due to excessive temperature.

[0161] See Figure 6 , Figure 6 for Figure 1a The diagram shows the structure of the auxiliary light source assembly of the undercarriage inspection equipment; as shown.

Figure 7a As shown, specifically, the first anti-collision block 510 has a first groove 511 on the side facing the top plate 110, and the bottom of the groove 511 facing the top plate 110 is higher than the main light source mounting base 210, the auxiliary light source mounting base 610 and the camera upper shell 310.

[0164] The first anti-collision block 510 has a first anti-collision block mounting hole 512 on its outer side away from the other anti-collision strip 500. The first anti-collision block 510 is fixedly connected to the top of the top plate 110 through the first anti-collision block mounting hole 512.

[0165] A crash bar 500 is installed on the top of the top plate 110, which enables the undercarriage inspection equipment to withstand greater crushing pressure, such as the crushing pressure of a 50-ton truck, thus enhancing the pressure resistance of the undercarriage inspection equipment.

[0166] Compared to a single-piece anti-collision strip, the embodiments of this application divide each anti-collision strip into three anti-collision blocks. Among them, the two first anti-collision blocks have the same structure and can use the same mold during production, which effectively reduces manufacturing costs.

[0167] See Figure 7b , Figure 7b for Figure 1a The diagram shows the bottom structure of the second anti-collision block of the undercarriage detection device; as shown. Figure 7b As shown, the second anti-collision block 520 has a second groove 521 on the side facing the top plate 110. The bottom of the groove 521 facing the top plate 110 is higher than the main light source mounting base 210, the auxiliary light source mounting base 610 and the camera upper shell 310.

[0168] The second anti-collision block 520 has a second anti-collision block mounting hole 522 on its outer side away from the other anti-collision strip 500.

[0170] In this embodiment, the undercarriage inspection device has an IP68 sealing rating, the bottom shell 100 is made of stainless steel, and the bottom shell 100 is equipped with a sufficiently thick anti-collision strip that can withstand the crushing force of a 50-ton truck. It has a built-in area scan camera assembly and a line scan camera assembly. The main light source assembly and the auxiliary light source assembly are installed on both sides of the area scan camera assembly and the line scan camera assembly. It can be buried in the ground to detect hazardous materials under vehicles passing over it. The area scan camera can be used to measure speed, and the line scan camera has a wide field of view and high accuracy. Blow heads are installed on both sides of the line scan camera to periodically clean the dust on the top of the lens cover.

[0171] See Figure 8a and Figure 8b , Figure 8a for Figure 1a A schematic diagram of the junction box assembly of the undercarriage inspection equipment shown. Figure 8b for Figure 8a An exploded view of the junction box assembly is shown; as follows: Figure 8a and Figure 8b As shown, it also includes: a junction box assembly 700; the junction box assembly 700 is disposed at the bottom of the bottom housing receiving space 130 of the bottom housing 100, connected to an external power supply, and electrically connected to the main light source assembly 200, the auxiliary light source assembly 600, and the camera assembly 300. The junction box assembly 700 can be fixed to the bottom of the bottom housing 100 with screws.

[0172] The junction box assembly 700 includes a junction box top cover 710 and a junction box bottom cover 720, which are fixedly connected.

[0173] The junction box lower housing 720 has a wiring circuit board 740 inside, which is electrically connected to the main light source assembly 200, the auxiliary light source assembly 600, and the camera assembly 300.

[0174] The junction box lower housing 720 is also provided with a third airtightness test nut 750, which is used to test the airtightness of the junction box assembly 700.

[0175] like Figure 8a and Figure 8b As shown, the junction box assembly 700 connects to the main cable 800, and the lower housing 720 of the junction box is provided with a second through hole 721 for the main cable. The main cable 800 is connected to the wiring circuit board 740 and passes through the second through hole 721 and the first through hole 140 for the main cable to connect to the external power supply.

[0176] The wiring circuit board 740 is also connected to the main light source cable 260, the camera cable 330, and the auxiliary light source cable 660. The other end of the main light source cable 260 passes through the main light source cable through hole opened on the main light source housing 223 and is connected to the main light source assembly 200. The other end of the camera cable 330 passes through the camera cable through hole opened on the camera housing 322 and is electrically connected to the camera circuit board 325.

[0177] There is also a reserved space for wiring between the bottom of the camera housing 322 and the bottom of the base 100 for the main light source cable 260 and the camera cable 330 to be routed. The bottom of the base 100 is also provided with a cable distribution post 160 for cable management, which separates the cables of different components on both sides, making it easier to distinguish the cables of each component.

[0178] The main light source cable 260 and the main light source assembly 200, the camera cable 330 and the camera circuit board 325, and the auxiliary light source cable 660 and the auxiliary light source assembly 600 can be connected via aviation plugs to achieve detachable connection between the junction box assembly and the main light source assembly, camera assembly, and auxiliary light source assembly. This allows for easy disassembly and reassembly of different components, making it easier for maintenance personnel to perform targeted repairs.

[0179] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
