[0038] One aspect of the present invention provides a vehicle-mounted security inspection system. For example... Figure 1 and Figure 2 As shown, the vehicle-mounted security inspection system includes: a vehicle 100, the vehicle 100 including a carriage 101; a tilting chamber module, including a tilting chamber 200 and a first radiation source 201 and a first detector 202 housed within the tilting chamber 200; and a tilting mechanism supported on the top of the carriage 101 for tilting the tilting chamber module. Figure 1 and Figure 2 In the illustration, vehicle 100 is shown as a van, but it is understood that vehicle 100 could also be a chassis, an AGV (Automated Guided Vehicle), or another mobile platform. The van 101 has a roof ( Figure 1 The left and right sides are defined based on the forward direction of the movable platform of the vehicle 100. In this invention, the first side is defined as the upper side, the first side, and the second side. Figure 1 The left side of the middle, the second side mentioned above is Figure 1 The right side (it should be understood that "first side" and "second side" are only used to distinguish the two sides and do not imply any order or sequence of use). Additionally, "top" or "upper side" of carriage 101 refers to the entire upper surface of carriage 101, unless otherwise stated. The first radiation source 201 and the first detector 202 constitute the first backscattering device. (As...) Figure 3As shown, the left side portion of the carriage 101 includes a recess 102 in which the tilting cabin module can be accommodated. For example, in one embodiment, a recessed platform 103 can be provided in the recess 102, on which the tilting cabin module can be placed, which is beneficial for stable positioning and holding of the tilting cabin module during backscatter scanning and for maintaining the stability of the tilting cabin module during vehicle transportation.

[0039] Figure 1 An advantageous manner is shown, for example, the shape and size of the recess 102 are set to match the tilting compartment 200, such that when the tilting compartment 200 is accommodated in the recess 102, the tilting compartment 200 is placed on the recess platform 103 to fill the recess 102, and the outer surface of the tilting compartment 200 provides the left side surface of the carriage 101, the carriage 101 having an overall shape that is approximately close to the complete cuboid shape without the recess 102. This configuration is aesthetically pleasing and makes full use of the volume of the carriage 101.

[0040] In other embodiments, the volume of the recess 102 may be larger than the volume or external dimensions of the tilting compartment 200, so that when the tilting compartment 200 is accommodated in the recess 102, it will not protrude beyond the extension line (outer contour) of the rest of the vehicle body 101, which is beneficial for maneuverability in transportation and will not cause the vehicle dimensions to violate relevant regulations. However, the tilting compartment 200 may partially protrude beyond the outer contour of the vehicle body 101 when placed in the recess 102, which is also an embodiment of the present invention.

[0041] In this embodiment, the flipping mechanism and the flipping compartment module are configured such that, when the flipping compartment module is in its initial position, it is held in a recess 102 below the top of a first side of the carriage 101, for example, on a recessed platform 103 within the recess 102, and after the flipping compartment module is flipped 180 degrees by the flipping mechanism, it is held in a position at the top of a second side of the carriage 101, for example, on a top platform 104 of the carriage 101. It is understood that the top platform 104 is a portion of the upper surface of the carriage 101 used to hold the flipping compartment module after it has been flipped 180 degrees. In some embodiments, the recess 102 may be an inwardly recessed notch or a stepped structure formed by removing the upper left portion of the carriage 101 along the forward direction of the vehicle 100. Advantageously, the recess 102 may be located approximately in the middle of the carriage 101 along the forward direction. Setting up a top platform 104 is advantageous, as the flip chamber module can be placed on the top platform 104, thereby enabling the flip chamber module to be positioned and kept stable together with the flip arm 302 of the flipping mechanism, which is beneficial for backscatter scanning.

[0042] exist Figure 1In the illustrated embodiment, the vehicle-mounted security inspection system is configured such that when the tilting chamber module is housed in the recess 102 on the first side of the vehicle compartment 101 (i.e., when the tilting chamber module is in its initial position), the first X-ray source 201 within the tilting chamber module can emit X-rays outward from the first side of the vehicle compartment 101 via the emitting surface 205 of the tilting chamber 200, so that the vehicle-mounted security inspection system can provide a first-side-view backscatter scan. The emitting surface 205 of the tilting chamber 200 is provided by the first X-ray source 201 and the second detector 202; in other words, the arrangement of the first X-ray source 201 and the second detector 202 determines the emitting surface 205 of the tilting chamber 200. At this time, an additional detector (not shown) can be provided in the recessed platform 103. This additional detector, together with the first detector 202, receives reflected X-rays when the first X-ray source 201 emits X-rays, thereby increasing the amount of reflected X-rays received, which is beneficial for subsequent image signal enhancement and provides a first-side image-enhanced backscatter scan. It is advantageous to install additional detectors in the recessed platform 103, as it can make full use of the space in the carriage and arrange more detectors to provide a larger detection area.

[0043] In this embodiment, the emitting surface 205 of the flip-over chamber 200 is the outer surface, and the first radiation source 201 and the first detector 202 are arranged relative to the emitting surface 205, that is, the first radiation source 201 and the first detector 202 are arranged substantially along the emitting surface 205. This embodiment can directly begin backscatter scanning of the object W located on the first side when the vehicle is moved to a suitable position.

[0044] In this invention, the flipping mechanism of the vehicle-mounted security inspection system includes a first flipping shaft 301 and a flipping arm 302. The first flipping shaft 301 is mounted on the top of the vehicle compartment 101. The first end of the flipping arm 302 is connected to the first flipping shaft 301, and the second end of the flipping arm 302 is connected to the flipping chamber 200, so that the second end of the flipping arm 302 and the flipping chamber module can flip around the first flipping shaft 301 from the first side to the second side of the vehicle compartment 101. The second end of the flipping arm 302 is the opposite end of the first end of the flipping arm 302. A first radiation source 201 and a first detector 202 within the flipping chamber 200 are arranged, for example, with the first radiation source 201 close to the first flipping shaft 301 and the first detector 202 away from the first radiation source 201 relative to the first flipping shaft 301. When the flipping chamber module is in its initial position and is held in the recess 102 on the first side of the vehicle compartment 101, the emitting surface 205 of the flipping chamber 200 constitutes part of the outer surface of the first side of the vehicle compartment. Figure 1 As shown; when the tilting capsule 200 is tilted 180 degrees via the first tilting shaft 301, and the tilting capsule module is held on the top platform 104 on the second side of the carriage 101 (at this time, the tilting capsule module is in the first position), the launching surface 205 of the tilting capsule 200 faces the second side of the carriage 101, as... Figure 3 As shown.

[0045] Due to the tilting mechanism, the tilting compartment module can be tilted from its initial position on the first side, i.e., the position accommodated in the recess 102, to the second side of the vehicle as needed. For example, as Figure 3 As shown, after the tilting chamber module is tilted 180 degrees together with the second end of the tilting arm 302 via the first tilting shaft 301, the tilting chamber module is held at the top of the second side of the carriage 101, for example on the top platform 104. The first X-ray source 201 inside the tilting chamber module can emit X-rays outward from the second side of the carriage 101 from the emission surface 205 of the tilting chamber 200, providing a backscattered scan of the high-angle view of the second side. Figure 3 In the middle, the second end of the tilting arm 302 is tilted 180 degrees and placed directly on, for example, the top platform 104 and holds the tilting cabin module.

[0046] The tilting mechanism may include a drive mechanism, such as a motor, configured to drive the first tilting shaft 301 to tilt. This is advantageous because the tilting of the tilting chamber 200 can be automatically controlled by the motor. The motor may be located at the first tilting shaft 301. The drive mechanism may also be a hydraulic mechanism.

[0047] In another embodiment of the invention, such as Figure 1 and Figure 3 As shown, the vehicle compartment 101 includes a second X-ray source 401 and a second detector 402 located on the second side inside the vehicle compartment 101. This allows the vehicle-mounted security inspection system to provide a second-side-view backscatter scan, for example, the second X-ray source 401 emitting X-rays outward from the second-side surface of the vehicle compartment 101. The second X-ray source 401 and the second detector 402 constitute a second backscattering device, and the second-side surface of the vehicle compartment 101 can be considered as the emitting surface 204 of the second backscattering device. This description is only to distinguish the emitting surface 204 of the second backscattering device from the emitting surface 205 of the flip-over chamber 200. In this embodiment, when the flip-over chamber module is housed in the recess 102 on the first side, the vehicle-mounted security inspection system can simultaneously provide a first-side-view backscatter scan of an object W located on the first side of the vehicle compartment 101 and a second-side-view backscatter scan of an object W located on the second side, thus forming a dual-channel side-view backscatter scan, which offers high flexibility and broad application scenarios.

[0048] Furthermore, in embodiments including a second backscattering device, the tilting cabin module can be tilted 180 degrees and held on the top platform 104 on the second side of the carriage 101, as shown below. Figure 3As shown, the first X-ray source 201 in the flip-up cabin module emits X-rays outward from the second side through the emitting surface 205 of the flip-up cabin 200 at the top of the cabin 101. At the same time, the second X-ray source 401 inside the cabin 101 can emit X-rays outward from the emitting surface 204 of the second backscattering device (the second side surface of the cabin 101). In this way, the vehicle-mounted security inspection system can realize backscatter scanning of ultra-tall objects, providing a second-side height-increasing backscatter scanning view, which makes it able to adapt to taller objects W and improve adaptability.

[0049] from Figure 1 and Figure 3 As can be seen, during the process of the flip arm 302 flipping from 0 degrees (i.e., the flip cabin module is in the initial position) to 180 degrees together with the flip arm 302, the flip cabin 200 and the flip arm 302 maintain a relatively fixed positional relationship. During this process, the orientation of the flip cabin 200 is reversed. The launch surface 205 of the flip cabin 200, which was facing outward from the first side of the carriage 101 in the initial position, is flipped to face outward from the second side of the carriage 101. That is, the launch surface 205 is flipped 180 degrees.

[0050] In another embodiment of the invention, the flipping mechanism may further include a second flipping shaft 303 connecting the second end of the flipping arm 302, and the flipping chamber 200 is connected to the flipping arm 302 via the second flipping shaft 303. This is advantageous, as the flipping chamber module can be further flipped around the second flipping shaft 303. In this embodiment, as... Figure 4 As shown, after the tilting arm 302 tilts 180 degrees, the tilting chamber 200 can be further tilted via the second tilting shaft 303, for example, by 90 degrees. At this time, the tilting chamber 200 is tilted to the top outside of the second side of the carriage 101, and the emitting surface 205 of the tilting chamber 200 is further tilted downwards. At this time, the tilting chamber module is in the second position. Thus, in this embodiment, the tilting mechanism is configured such that after the tilting chamber 200 is tilted 180 degrees together with the second end of the tilting arm 302 via the first tilting shaft 301, it can be further tilted by 90 degrees via the second tilting shaft 303, so as to emit rays downwards from the second side of the top of the carriage 101, providing a second-side top-view backscatter scan of the object W located on the second side.

[0051] It should be noted that the second flip axis 303 can rotate less than 90 degrees, that is, any angle within 0 to 90 degrees, and also any angle exceeding 90 degrees, which can be flexibly set as needed.

[0052] According to an embodiment of the present invention, in order to achieve the rotation of the second flipping shaft 303, the flipping mechanism may include a telescopic mechanism 305, configured to drive the flipping chamber module to flip around the second flipping shaft 303 by telescopic movement. The telescopic mechanism 305 may include a telescopic arm, one end of which is connected to the flipping chamber 200, and the other end of which is connected to the flipping arm 302. The telescopic arm pushes the flipping chamber 200 by telescopic movement, causing the flipping chamber 200 to flip around the second flipping shaft 303. The telescopic arm may include, for example, a hydraulic arm. The telescopic mechanism 305 is advantageous because, compared to providing a motor on the second flipping shaft 303, the telescopic mechanism 305 is lightweight and can provide a triangular structure together with the flipping arm 302, so that the flipping chamber 200 and the flipping arm 302 form a stable structure, thereby enabling the flipping chamber module to maintain a stable positional relationship throughout the flipping process, and the telescopic mechanism 305 can be self-fixed.

[0053] In an embodiment of the present invention, after the tilting arm 302 and the tilting chamber module are tilted together to 180 degrees, the tilting chamber module is further tilted 90 degrees around the second tilting axis 303. The emitting surface 205 of the tilting chamber module faces downward, and the first backscattering device can perform a top-view backscattering scan. At this time, the second backscattering device in the carriage 101 can simultaneously perform a backscattering scan, that is, a second side-view backscattering scan. Thus, the vehicle-mounted security inspection system can realize the inspection of the object W located on the second side of the vehicle from two perspectives.

[0054] In embodiments of the present invention, the first X-ray source 201 and the second X-ray source 401 can emit pencil-shaped X-ray beams, such as flying-spot scanning beams, to provide fan-shaped scanning. Preferably, both the first X-ray source 201 and the second X-ray source 401 emit approximately fan-shaped pencil-shaped X-ray beams located in a vertical plane. The first backscattering device performs top-view backscattering scanning, meaning the center line of the fan-shaped pencil-shaped X-ray beam emitted by the first X-ray source 201 is along an approximately vertical direction. The first backscattering device and the second backscattering device perform side-view backscattering scanning, meaning the center lines of the fan-shaped pencil-shaped X-ray beams emitted by the first X-ray source 201 and the second X-ray source 401 are along an approximately horizontal and approximately vertical direction. The fan-shaped pencil-shaped X-ray beams emitted by the first X-ray source 201 and the second X-ray source 401 may or may not be located in the same vertical plane.

[0055] According to the vehicle-mounted security inspection system of the present invention, due to the provision of a flipping mechanism, the flipping chamber module can be held in the recess 102 of the vehicle compartment 101 during vehicle transportation, so that the vehicle does not protrude and does not affect driving safety; and, by holding the flipping chamber module in the recess 102, the vehicle's first side-view backscatter scanning, the second side high-position side-view backscatter scanning (the flipping chamber 200 is flipped 180 degrees, and the emitting surface 205 faces outward from the second side), and the second side top-view backscatter scanning can be flexibly configured and mutually converted; furthermore, since the vehicle compartment 101 of the present invention is provided with a second backscattering device, the vehicle-mounted security inspection system can simultaneously provide dual-channel backscatter scanning on both sides of the vehicle 100, as well as second side high-position side-view backscatter scanning and second side top-view and second side-view dual-view backscatter scanning.
