[0047] This application provides a scanning imaging device. The scanning imaging device of this application will be described in detail below with reference to the accompanying drawings. Without conflict, the features in the following embodiments and implementation manners may be combined with each other.

[0048] Figure 1 Shown is a perspective view of a scanning imaging device 100 according to an exemplary embodiment of this application. Refer to Figure 1 As shown, this application provides a scanning imaging device 100, including a bracket 10, a scanning assembly 11 and a connection assembly 12. The scanning imaging device 100 can be applied to human or item imaging security inspection technologies, and can include millimeter wave security scanners, X-ray security scanners, etc. Among them, a millimeter wave security scanner can use a device that emits and receives millimeter waves to perform a security scan of a human body to determine whether there are suspicious items hidden on the surface of the inspected human body.

[0049] The scanning assembly 11 is disposed on the bracket 10 and includes a scanner 13. Among them, the scanner 13 can be a millimeter-wave scanner, which is mainly used for transmitting and receiving millimeter-wave signals. The scanner 13 includes a first scanner 14 and a second scanner 15. The first scanner 14 and the second scanner 15 are oppositely arranged on opposite sides of the bracket 10 and can move relative to the bracket 10. The first scanner 14 can scan the first side of a human body or an object, and the second scanner 15 can scan the second side of the human body or the object. The first side and the second side are opposite to each other, so that double-sided scanning of the human body or the object can be realized. In some embodiments, the bracket 10 includes a first doorframe structure 16 and a second doorframe structure 17 that are relatively and separately arranged in the horizontal direction. The scanning and imaging device 100 includes a guiding track 18. The guiding track 18 is disposed on the bracket 10 and includes a first guiding track 19 and a second guiding track 20. The first guiding track 19 is arranged inside the first doorframe structure 16, and the second guiding track 20 is arranged inside the second doorframe structure 17. The first scanner 14 is slidably arranged on the first guiding track 19. The second scanner 15 is slidably arranged on the second guiding track 20. By using the first guiding track 19 and the second guiding track 20, the movement of the first scanner 14 and the second scanner 15 can be made smoother and the movement stability is better.

[0050] In some embodiments, the scanning and imaging device 100 includes a driving assembly 24 (see Figure 12 shown). The driving assembly 24 is disposed on the bracket 10 and is connected to the first scanner 14 for driving the first scanner 14 to move in the vertical direction. The first scanner 14 drives the second scanner 15 to move in the vertical direction through the connecting assembly 12. The moving directions of the first scanner 14 and the second scanner 15 are opposite. By using the driving assembly 24 to drive the first scanner 14 to move in the vertical direction, since the first scanner 14 and the second scanner 15 are connected by the connecting assembly 12, the first scanner 14 can drive the second scanner 15 to move in the opposite direction. Thus, a single operation of the driving assembly 24 can realize double-sided scanning of a human body or an object, further improving the working efficiency. Moreover, the driving assembly 24 only needs to drive the first scanner 14 to move, reducing the power requirement of the whole machine.

[0051] The connecting assembly 12 includes a connecting belt 21 in the shape of a band. In this embodiment, the connecting belt 21 can be a steel belt, and its outer shape is usually flat. One end of the connecting belt 21 is connected to the first scanner 14, and the other end is connected to the second scanner 15 for connecting the first scanner 14 and the second scanner 15. The connecting belt 21 includes a metal part 22 extending along the extension direction of the connecting belt 21 (see Figure 11As shown in the figure, the metal part 22 can be a metal strip or a metal rope. When the metal part 22 is a metal strip, the number thereof can be one; when the metal part 22 is a metal rope, the number thereof is at least two. In this embodiment, the metal part 22 can be a steel wire core provided in a steel strip, and the number of the steel wire cores is multiple, and they are arranged side by side along the width direction of the steel strip. The metal part 22 connects the first scanner 14 and the second scanner 15. In some embodiments, the connecting belt 21 includes a non-metal layer 23 wrapped outside the metal part 22 (see Figure 10 shown in the figure), so that the wear of the metal part 22 can be reduced or prevented, and the metal part 22 can be isolated from the external environment, preventing electric conduction and electric shock, and improving the safety performance of the whole machine. In this embodiment, the non-metal layer 23 can be a polyurethane elastomer in the steel strip. In some embodiments, the surface of the non-metal layer 23 is injection-molded and coated with a silent and wear-resistant material, which can reduce the wear of the non-metal layer 23 during the operation of the scanning imaging device 100 and can also play a role in reducing noise.

[0052] Compared with using a steel wire rope to connect two relatively moving components, the connecting belt 21 includes a metal part 22 along the extending direction of the connecting belt 21, so that the strength of the connecting belt 21 is higher than that of the steel wire rope. The connecting belt 21 is connected to the first scanner 14 and the second scanner 15. In this way, the design of the scanning imaging device is simpler, facilitating installation and disassembly. The belt-shaped connecting belt 21 including the metal part is not easily broken, has high safety, improves the connection stability between the first scanner 14 and the second scanner 15, thereby improving the safety performance of the scanning imaging device 100. And the first scanner 14 and the second scanner 15 are connected by the connecting belt 21, so that the first scanner 14 and the second scanner 15 can move synchronously.

[0053] Figure 2 As shown in the figure is Figure 1 a three-dimensional schematic diagram of the scanner fixing seat 25 and the connecting component 12 of the scanning imaging device 100 shown in the figure; Figure 3 As shown in the figure is Figure 1 a partial three-dimensional schematic diagram of the scanner fixing seat 25 and the connecting component 12 of the scanning imaging device 100 shown in the figure; Figure 4 As shown in the figure is Figure 3 a front view of the scanner fixing seat 25 and the connecting component 12 of the scanning imaging device 100 shown in the figure; Figure 5 As shown in the figure is Figure 3 a three-dimensional exploded view of the scanner fixing seat 25 and the connecting component 12 of the scanning imaging device 100 shown in the figure. See Figures 1 to 5As shown, in some embodiments, the scanning assembly 11 includes a scanner fixing base 25, the scanner 13 is fixedly arranged on the scanner fixing base 25, and the scanner fixing base 25 is movably connected to the bracket 10. In some embodiments, the scanner fixing base 25 includes a first scanner fixing base 26 and a second scanner fixing base 27. The first scanner 14 is fixedly arranged on the first scanner fixing base 26, and the second scanner 15 is fixedly arranged on the second scanner fixing base 27. The first scanner fixing base 26 is slidably arranged on the first guiding track 19, and the second scanner fixing base 27 is slidably arranged on the second guiding track 20. The connecting assembly 12 includes a connecting belt fixing structure 28. The connecting belt 21 is connected to the scanner fixing base 25 through the connecting belt fixing structure 28. The connecting belt fixing structure 28 is provided to fix the connecting belt 21 to the scanner fixing base 25 and prevent the connecting belt 21 from detaching from the scanner fixing base 25. In some embodiments, the first scanner 14 can be connected to the first scanner fixing base 26 through the connecting belt fixing structure 28; and / or the second scanner 14 can be connected to the second scanner fixing base 27 through the connecting belt fixing structure 28. In some embodiments, the connecting assembly 12 includes a connecting belt anti-slip structure 29. The connecting belt anti-slip structure 29 is in frictional connection with the connecting belt 21. The connecting belt anti-slip structure 29 is provided to cooperate with the connecting belt fixing structure 28 to further prevent the connecting belt 21 from detaching from the scanner fixing base 25 and ensure the safety performance of the scanning imaging device 100.

[0054] Figure 6 As shown Figure 3 The three-dimensional exploded view of the connecting belt fixing structure 28 of the connecting assembly 12 of the scanning imaging device 100 shown. Refer to Figures 1 to 6 As shown, in some embodiments, the connecting belt fixing structure 28 includes a first fixing plate 30 and a second fixing plate 31 arranged opposite to the first fixing plate 30. The first fixing plate 30 is fixedly connected to the scanner fixing base 25. The connecting belt 21 is clamped between the first fixing plate 30 and the second fixing plate 31. The connecting belt 21 is fixed by the pressing force between the first fixing plate 30 and the second fixing plate 31. The fixing method is simple and the operation is convenient. Moreover, the contact areas of the first fixing plate 30, the second fixing plate 31 and the connecting belt 21 are relatively large, and the fixing effect of the connecting belt 21 is good. In some embodiments, the second fixing plate 31 is detachably arranged on the first fixing plate 30. The first fixing plate 30 and the second fixing plate 31 can be connected by bolts, and the pressing force between the first fixing plate 30 and the second fixing plate 31 can depend on the tightening torque of the bolts. In some embodiments, a groove 32 is arranged on the surface of the first fixing plate 30 facing the second fixing plate 31. The connecting belt 21 is clamped in the groove 32. In this way, the connecting belt 21 can be limited in position to prevent the connecting belt 21 from changing its position due to accidental collision, and the arrangement of the groove 32 facilitates the repeated installation and positioning of the connecting belt 21.

[0055] Figure 7 As shown Figure 6 A three-dimensional schematic diagram of the second fixing plate 31 of the connection belt fixing structure 28 of the scanning imaging device 100 shown; Figure 8 As shown Figure 4 A cross-sectional view of the scanner fixing base 25 and the connection component 12 of the scanning imaging device 100 shown along the line A-A. Refer to Figure 7 and Figure 8 As shown, in some embodiments, a first anti-slip protrusion 33 is provided on the surface of the second fixing plate 31 facing the first fixing plate 30. The first anti-slip protrusion 33 can be a toothed protrusion, so the anti-slip effect is better. The first anti-slip protrusion 33 presses against the surface of the connection belt 21, which can increase the friction between the second fixing plate 31 and the connection belt 21, improve the connection stability between the connection belt 21 and the first fixing plate 30 and the second fixing plate 31, make the fixing effect of the connection belt 21 better, and make it less likely to come off. The force exerted by the first anti-slip protrusion 33 on the surface of the connection belt 21 depends on the pressing force between the first fixing plate 30 and the second fixing plate 31. Excessive pressing force between the first fixing plate 30 and the second fixing plate 31 may cause the surface of the connection belt 21 to be broken, exposing the metal part 22 inside the connection belt 21. The exposure of the metal part 22 may cause a short circuit in the circuit of the connection belt detection structure 48. In some embodiments, the surface of the first anti-slip protrusion 33 in contact with the connection belt 21 is made of an insulating material, which can prevent the phenomenon that the first anti-slip protrusion 33 breaks the surface of the connection belt 21 and causes the connection belt detection structure 48 to fail.

[0056] Refer again to Figure 2 and Figure 3As shown, in some embodiments, the first fixing plate 30 includes a movable plate 35 and a connecting plate 36. The connecting belt 21 extends into the space between the movable plate 35 and the second fixing plate 31 along the first direction X and is clamped between the movable plate 35 and the second fixing plate 31. The connecting plate 36 is fixedly connected to the scanner fixing base 25. The connecting plate 36 can be fixedly connected to the scanner fixing base 25 by detachable connection means such as bolt connection, or the connecting plate 36 can also be fixedly connected to the scanner fixing base 25 by non-detachable connection means. The movable plate 35 is connected to the connecting plate 36, and the distance between the movable plate 35 and the connecting plate 36 in the first direction X is adjustable. By adjusting the distance between the movable plate 35 and the connecting plate 36, the relative positional relationship between the first scanner 14 and the second scanner 15 can be adjusted. During the use of the scanning imaging device 100, the position of the movable plate 35 relative to the connecting plate 36 remains unchanged. At this time, the movable plate 35 can be fixed to the scanner fixing base 25. During the debugging and installation of the scanning imaging device 100, the movable plate 35 is adjustable so that the distance between the movable plate 35 and the connecting plate 36 changes. In some embodiments, the first fixing plate 30 includes a connecting member 37. Among them, the connecting member 37 can be a bolt. The movable plate 35 is provided with a sliding groove 38. The connecting member 37 passes through the sliding groove 38 and is detachably connected to the scanner fixing base 25 to fix the movable plate 35 to the scanner fixing base 25. The sliding groove 38 extends in the first direction X, and the position of the connecting member 37 in the sliding groove 38 is adjustable in the first direction X. That is, when the connection between the connecting member 37 and the scanner fixing base 25 is loose, the connecting member 37 can slide in the sliding groove 38 in the first direction X, so that the distance between the movable plate 35 and the connecting plate 36 in the first direction X is adjustable. Taking the example that the first scanner 14 is provided with a connecting belt fixing structure 28 and the driving assembly 24 is connected to the first scanner 14, since the driving assembly 24 has a brake function, the first scanner 14 will be locked, making the first scanner 14 unable to move. When the distance between the movable plate 35 and the connecting plate 36 increases, the whole of the movable plate 35, the second fixing plate 31 and the connecting belt 21 will move in the opposite direction of the first direction X, and the whole of the second scanner 15 will move in the first direction X. Vice versa. In some embodiments, the first fixing plate 30 includes a fixing member 58 and a fixing fitting 59 provided on the fixing member 58. The fixing fitting 59 includes a first fixing fitting 60 and a second fixing fitting 61. The fixing member 58 connects the movable plate 35 and the connecting plate 36. Among them, the fixing member 58 can be a bolt, and the fixing fitting 59 can be a nut. The first fixing fitting 60 and the second fixing fitting 61 clamp the movable plate 35, and their positions on the fixing member 58 are adjustable in the first direction X, so that the distance between the movable plate 35 and the connecting plate 36 in the first direction X is adjustable. Such a setting fixes the connecting plate 36 and the movable plate 35, making the installation of the movable plate 35 more stable.

[0057] See Figure 8As shown, in some embodiments, the connecting belt anti-slip structure 29 includes an anti-sliding block 39, and the anti-sliding block 39 is pressed against the side of the connecting belt fixing structure 28 facing away from the scanner fixing seat 25. The connecting belt 21 passes through the connecting belt fixing structure 28 from the first direction X, bypasses the anti-sliding block 39, and extends from the side of the anti-sliding block 39 facing away from the connecting belt fixing structure 28 to the direction opposite to the first direction X. The opposite direction of the first direction X mentioned here can be a directly opposite direction or an obliquely opposite direction. For example, when the first direction X is vertically downward, the opposite direction of the first direction X can be a vertically upward or obliquely upward direction. The side of the anti-sliding block 39 facing away from the connecting belt fixing structure 28 is frictionally connected to the connecting belt 21, so that the connecting belt 21 is less likely to be separated from the connecting belt anti-sliding structure 29. When the connecting belt fixing structure 28 fails, the scanner fixing seat 25 falls due to gravity, and the anti-sliding block 39 moves together with the scanner fixing seat 25. Since the connecting belt 21 bypasses the anti-sliding block 39 and extends from the side of the anti-sliding block 39 facing away from the connecting belt fixing structure 28 to the direction opposite to the first direction X, and the side of the anti-sliding block 39 facing away from the connecting belt fixing structure 28 is frictionally connected with the connecting belt 21, the anti-sliding block 39 will abut against the surface of the connecting belt 21, play a role in supporting the connecting belt 21 and buffering, and the connecting belt anti-slip structure 29 can cooperate with the connecting belt fixing structure 28 to prevent the connecting belt 21 from loosening, thereby enhancing the safety performance of the whole machine. In some embodiments, the thickness of the anti-sliding block 39 along the first direction X and in the second direction Y perpendicular to the first direction X gradually increases, and the connecting belt fixing structure 28 and the anti-sliding block 39 are arranged in the second direction Y, which can reduce the weight of the anti-sliding block 39 while ensuring the anti-slip performance of the anti-sliding block 39.

[0058] In some embodiments, the connecting belt anti-slip structure 29 includes an anti-slip block fixing plate 42, and the anti-slip block fixing plate 42 is connected to the scanner fixing seat 25 or the connecting belt fixing structure 28, wherein the anti-slip block fixing plate 42 can be connected to the first fixing plate 30 or the second fixing plate 31, and the anti-loosening effect of connecting the first fixing plate 30 and the scanner fixing seat 25 is better. The anti-slip block 39 is clamped between the connecting belt fixing structure 28 and the anti-slip block fixing plate 42, so that the anti-slip block 39 is restricted between the connecting belt fixing structure 28 and the scanner fixing seat 25, so that the fixing method is simple and the installation is convenient. The connecting belt 21 is clamped between the anti-slip block 39 and the anti-slip block fixing plate 42, so that the side of the anti-slip block 39 facing away from the connecting belt fixing structure 28 is frictionally connected with the connecting belt 21, and the connecting belt 21 is clamped between the anti-slip block 39 and the anti-slip block fixing plate 42, so that the fixing effect is better, and the loosening of the connecting belt 21 can be better prevented.

[0059] When the connection belt fixing structure 28 becomes loose and fails, the scanner fixing base 25 drops due to gravity. The anti-slip block 39 moves together with the scanner fixing base 25. Since the connection belt 21 bypasses the anti-slip block 39, it extends from the side of the anti-slip block 39 facing away from the connection belt fixing structure 28 in the direction opposite to the first direction X. The connection belt 21 will push the anti-slip block 39 in the direction exactly opposite to the first direction X. Since the thickness of the anti-slip block 39 gradually increases in the first direction X and in the second direction Y perpendicular to the first direction X, and the gap between the connection belt fixing structure 28 and the scanner fixing base 25 is constant, the connection belt 21 pushing the anti-slip block 39 will make the distance between the anti-slip block 39 and the connection belt fixing plate 42 smaller and smaller, so that the connection belt 21 clamped between the anti-slip block 39 and the connection belt fixing plate 42 is pressed tighter and tighter by the anti-slip block 39 and the connection belt fixing plate 42. The anti-slip block 39 can support the connection belt 21, and the anti-slip block 39 and the connection belt fixing plate 42 can clamp the connection belt 21, which can better prevent the loosening of the connection belt 21 and make the safety performance of the scanning imaging device 100 better.

[0060] In some embodiments, the anti-slip block 39 includes a first anti-slip end portion 40 and a second anti-slip end portion 41 opposite to each other in the first direction X. The connection belt 21 bypasses the second anti-slip end portion 41 and extends towards the first anti-slip end portion 40. The anti-slip block fixing plate 42 is provided with an opening 43. The opening 43 is arranged closer to the first anti-slip end portion 40 relative to the second anti-slip end portion 41. The connection belt 21 passes through the opening 43 and extends outside the anti-slip block fixing plate 42. The opening 43 is arranged closer to the first anti-slip end portion 40 relative to the second anti-slip end portion 41, which can increase the contact area between the connection belt 21 and the anti-slip block fixing plate 42 to expand the frictional force between the connection belt 21 and the anti-slip block fixing plate 42, making the anti-loosening effect of the connection belt anti-slip structure 29 better.

[0061] In some embodiments, the anti-slip block 39 includes a connecting portion 44 connecting the first anti-slip end portion 40 and the second anti-slip end portion 41; the connecting portion 44 is provided with a limiting structure 45, and the connection belt fixing structure 28 is provided with a limiting and matching structure 46. In this embodiment, the limiting and matching structure 46 is arranged on the second fixing plate 31. The limiting structure 45 cooperates with the limiting and matching structure 46 to limit the movement of the anti-slip block 39 in the first direction X. The arrangement of the limiting structure 45 and the limiting and matching structure 46 facilitates the repeated assembly of the anti-slip block 39 and the connection belt fixing structure 28, limits the displacement of the anti-slip block 39, and makes the fixing effect of the anti-slip block 39 better.

[0062] Figure 9 As shown Figure 5 A three-dimensional schematic diagram of the anti-slip block 39 of the connection assembly 12 of the scanning imaging device 100 shown. Refer to Figure 8 and 9As shown, on the side of the anti-slip block 39 facing away from the connecting belt fixing structure 28, a second anti-slip protrusion 47 is provided. The second anti-slip protrusion 47 can be a dense tooth-shaped protrusion. The second anti-slip protrusion 47 presses against the connecting belt 21, which can increase the friction between the connecting belt 21 and the anti-slip block 39, making it more difficult for the connecting belt 21 to generate relative sliding and achieving a better fixing effect.

[0063] In some embodiments, the bottom surface of the second anti-slip end portion 41 is an arc surface. When the connecting belt fixing structure 28 becomes loose and fails, the arc surface can make the connecting belt 21 fit better with the bottom surface of the second anti-slip end portion 41, and the connecting belt 21 will not be worn or damaged due to friction or collision.

[0064] Figure 10 As shown Figure 5 A schematic plan view of the connecting belt detection structure 48 of the connecting component 12 of the scanning imaging device 100 shown; Figure 11 As shown Figure 10 A schematic diagram of the connecting belt detection structure 48 of the scanning imaging device 100 shown. Refer to Figure 10 and Figure 11 As shown, in some embodiments, the connecting belt 21 includes a plurality of metal parts 22 arranged side by side in the width direction of the connecting belt 21; the connecting component 12 includes a connecting belt detection structure 48. Among them, the connecting belt detection structure 48 can be arranged at any position of the connecting belt 21. In the embodiments of the present application, the number of the connecting belt detection structures 48 is two and they are arranged at both ends of the connecting belt 21. The connecting belt detection structure 48 includes a conductive part 49 and a conductive connecting head 50. The conductive part 49 penetrates into the connecting belt 21. The conductive part 49 can be a conductive connecting part such as a bolt or a self-tapping screw. The conductive part 49 conducts adjacent metal parts 22 to realize the series connection of the metal parts 22. The scanning imaging device 100 includes a controller. The conductive connecting head 50 connects the metal parts 22 and the controller. The controller is used to detect the electrical signal of the metal parts 22 and determine whether the metal parts 22 are broken according to the electrical signal. When the metal parts 22 are energized, since the plurality of metal parts 22 are connected in series, the controller can judge whether there is a broken metal part in the connecting belt 21 by judging the on-off of the current. The connecting belt detection structure 48 can be used to monitor the connecting belt 21 in real time to ensure the safety of the whole machine. And the connecting belt detection structure 48 is only composed of the conductive part 49 and the conductive connecting head 50. Its structure is simple and the cost is low. The conductive connecting head 50 can be set to a smaller volume, reducing the weight of the connecting component 12.

[0065] Figure 12 A perspective view of the scanning imaging device 100 of another exemplary embodiment of the present application with the bracket 10 removed; Figure 13 As shown Figure 12 A partially enlarged view of the scanning imaging device 100 with the bracket 10 removed shown. Figures 12 to 13The illustrated embodiment is similar to Figures 1 to 11 the embodiment of Figures 1 to 11 and, compared with Figures 12 to 13 the embodiment shown, the main differences are as follows: Figures 1 to 11 In the embodiment shown, the first fixing plate 30 includes a mounting member 56. The connecting plate 36 is fixed to the scanner fixing base 25 through the mounting member 56. The mounting member 56 is arranged along a third direction Z perpendicular to the first direction X and the second direction Y. The sliding groove 38 and the connecting plate 36 are arranged along the first direction X. In this way, the volume of the connecting plate 36 is larger, and the effect of mounting and fixing the movable plate 35 is better. Figures 12 to 13 In the embodiment shown, the first fixing plate 30 includes a mounting member 55. The connecting plate 53 is fixed to the scanner fixing base 25 through the mounting member 55. The mounting member 55 is arranged along the first direction X. The movable plate 52 is provided with a sliding groove 54. The sliding groove 54 and the connecting plate 53 are arranged along a third direction Z perpendicular to the first direction X and the second direction Y. In this way, the connecting plate 53 can be made narrower, so that the volume of the first fixing plate 30 can be reduced. Further, the volume of the scanner fixing base 25 can be reduced, making the weight of the scanner fixing base 25 lighter and facilitating the driving assembly 24 to drive the scanner fixing base 25 and the scanner 13 to move.
