If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0034] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0035] Reference Figures 1 to 13An X-ray imaging device includes: an X-ray assembly 100, a detector assembly 200, a bed assembly 300, a column assembly 400 and a movable slide rail assembly 500.

[0036] The bed assembly 300 is arranged on the ground. The movable slide assembly 500 is arranged on one side of the bed assembly 300. The detector assembly 200 is arranged in the bed assembly 300. The column assembly 400 is slidably arranged on the movable slide assembly 500. The X-ray assembly 100 is arranged on the column assembly 400 in a liftable manner. The detector assembly 200 is arranged in the bed assembly 300 and connected to the column assembly 400.

[0037] The bed assembly 300 includes a bed body 310 , a bed surface 320 , and a bed surface lifting assembly 330 .

[0038] The bed surface 320 is used to carry the patient, and the bed surface lifting assembly 330 is used to adjust the height of the bed surface 320. The detector assembly 200 rises and falls together with the bed surface 320.

[0039] The movable slide rail assembly 500 can drive the detector assembly 200 and the X-ray assembly 100 to be located at the detection position.

[0040] It is understandable that, in the embodiments of the present invention, the detector assembly 200 and the X-ray assembly 100 can be driven to move synchronously by moving the slide rail assembly 500, thereby greatly improving the operating efficiency of the operator. At the same time, in some embodiments of the present invention, when the detector assembly 200 and the X-ray assembly 100 need to be moved quickly, they can be moved quickly manually, further greatly improving the operating efficiency.

[0041] Reference Figures 1 to 8 The movable slide rail assembly 500 includes a track frame 510, a linear circular rail 520, a slide frame bottom plate 530 and a slide frame bottom plate driving mechanism 540. The track frame 510 is arranged on one side of the bed assembly 300. The length direction of the track frame 510 is consistent with the length direction of the bed assembly 300. The linear circular rail 520 is arranged on the track frame 510 along the length direction of the track frame 510. The slide frame bottom plate 530 is slidably arranged on the linear circular rail 520. The column assembly 400 is arranged on the slide frame bottom plate 530. The slide frame bottom plate driving mechanism 540 is used to drive the slide frame bottom plate 530 to slide along the linear circular rail 520.

[0042] It can be understood that by guiding the movement of the sliding frame bottom plate 530 through the linear circular rail 520, it is possible to ensure smooth movement, reduce friction, and ensure smooth movement.

[0043] Reference Figure 8 and Fig. 9The sliding frame bottom plate driving mechanism 540 includes a motor mounting frame 541, a reduction motor 542, a synchronous belt tensioning mechanism 543 and a synchronous belt 544. The motor mounting frame 541 is arranged at one end of the track frame 510. The reduction motor 542 is arranged on the motor mounting frame 541. The synchronous belt tensioning mechanism 543 is arranged at the other end of the track frame 510. After one end of the synchronous belt 544 is connected to one side of the sliding frame bottom plate 530, the other end of the synchronous belt 544 is connected to the other side of the sliding frame bottom plate 530 after bypassing the reduction motor 542 and the synchronous belt tensioning mechanism 543.

[0044] It is understandable that the reduction motor 542 drives the synchronous belt 544 to operate, thereby driving the sliding frame bottom plate 530 to slide along the linear circular rail 520, thereby driving the column assembly 400 to move.

[0045] Reference Figure 8 and Fig. 9 The sliding frame bottom plate driving mechanism 540 further includes a permanent magnet electromagnetic clutch 545. The permanent magnet electromagnetic clutch 545 is arranged on the reduction motor 542. When the permanent magnet electromagnetic clutch 545 is powered on, the reduction motor 542 is self-locking and fails.

[0046] It is understandable that the efficiency of driving the column assembly 400 to move by the reduction motor 542 is low. When the column assembly 400 needs to be moved significantly, the permanent magnet electromagnetic clutch 545 can be energized, and then the self-locking of the reduction motor 542 fails, and the operator can achieve rapid movement by pushing the column assembly 400.

[0047] Reference Figure 8 and Fig. 9 The sliding frame bottom plate driving mechanism 540 further includes a wire displacement sensor 546. The wire of the wire displacement sensor 546 is connected to the sliding frame bottom plate 530. When the sliding frame bottom plate 530 moves, the wire of the wire displacement sensor 546 is driven to move, and the wire displacement sensor 546 can detect the moving position of the sliding frame bottom plate 530.

[0048] After the column assembly 400 is manually moved, the position of the column assembly 400 can be detected by the pull-wire displacement sensor 546 to avoid excessive displacement control caused by subsequent electric drive.

[0049] Reference Figure 8 and Fig.10 The slide frame bottom plate driving mechanism 540 further includes a travel switch pressing plate 547 and a travel switch 548. The travel switch pressing plate 547 is arranged on the track frame 510. The travel switch 548 is arranged on the slide frame bottom plate 530. The travel switch 548 is attached to the travel switch pressing plate 547.

[0050] It is understandable that in some embodiments of the invention, the limit position of the slide frame bottom plate driving mechanism 540 is controlled by the travel switch pressing plate 547. During the movement of the slide frame bottom plate 530, the travel switch 548 is always in contact with the travel switch pressing plate 547. When the travel switch 548 is separated from the travel switch pressing plate 547, the reduction motor 542 stops. The control of the limit position can be achieved by controlling the length of the travel switch pressing plate 547.

[0051] Reference Figures 4 to 10 The detector assembly 200 includes a detector bracket 210, a flat-panel detector 220, a detector telescopic assembly 230, and a detector sliding mechanism 240. The detector bracket 210 is arranged in the bed assembly 300. The flat-panel detector 220 is arranged on the detector bracket 210. The detector sliding mechanism 240 includes a detector slide rail 241 and a detector slider 242. The detector slide rail 241 is arranged on one side of the bed assembly 300. The detector slider 242 is slidably arranged on the detector slide rail 241. One end of the detector telescopic assembly 230 is connected to the detector slider 242, and the other end is connected to the detector bracket 210. The detector telescopic assembly 230 is used to cooperate with the bed assembly 300 to rise and fall.

[0052] Reference Figures 4 to 10 , the detector assembly 200 also includes a centering mechanism 250. The centering mechanism 250 includes a centering positioning plate 251, a centering mechanism mounting plate 252, a centering guide block 253, a centering transmission rod 254, a first return spring 255, and a centering positioning bearing 256. The centering positioning plate 251 is arranged on the bottom plate 530 of the sliding frame. A positioning groove 251a is provided on the centering positioning plate 251. The centering mechanism mounting plate 252 is arranged on the detector slider 242. The centering guide block 253 is arranged on the centering mechanism mounting plate 252. The centering transmission rod 254 is inserted in the centering guide block 253. The centering positioning bearing 256 is arranged at one end of the centering transmission rod 254 and close to the centering positioning plate 251. One end of the first return spring 255 abuts on the centering guide block 253, and the other end abuts on the centering positioning bearing 256. The first return spring 255 can drive the centering and positioning bearing 256 to approach the centering and positioning plate 251. The centering and positioning bearing 256 can be accommodated in the locking groove 251a.

[0053] It is worth noting that during the detection process, the detector assembly 200 needs to be located directly below the X-ray assembly. In the embodiment of the present invention, the column assembly 400 and the detector assembly 200 are connected by the centering mechanism 250. When the column assembly 400 is moved, the centering positioning plate 251 drives the centering mechanism mounting plate 252 and the detector slider 242 to move, thereby driving the detector bracket 210 and the flat panel detector 220 to move together, so that the two can move synchronously. The operator does not need to distribute the operation of the column assembly 400 and the detector assembly 200, which saves the alignment time and greatly improves the operation efficiency.

[0054] Reference Figures 10 to 13 The column assembly 400 and the sliding frame bottom plate 530 are connected via a rotation positioning mechanism 550. The rotation positioning mechanism 550 is used to rotate or fix the column assembly 400.

[0055] Reference Figures 10 to 13 The rotation positioning mechanism 550 includes a slewing bearing 551, a rotating positioning plate 552, a first positioning pin 553, a second positioning pin 554, a hinge seat 555, a hinge plate 556, a second return spring 557, and a third return spring 558. The inner ring of the slewing bearing 551 is fixedly arranged on the bottom plate 530 of the sliding frame. The rotating positioning plate 552 is arranged on the outer ring of the slewing bearing 551. The column assembly 400 is arranged on the rotating positioning plate 552. The rotating positioning plate 552 is provided with a plurality of positioning holes 552a. The hinge seat 555 is arranged on the bottom plate 530 of the sliding frame. The hinge plate 556 is hinged to the hinge seat 555. One end of the first positioning pin 553 is hinged to the middle part of the hinge plate 556, and the other end passes through the bottom plate 530 of the sliding frame and is inserted into the positioning hole 552a. One end of the second positioning pin 554 passes through the bottom plate 530 of the sliding frame and abuts against one end of the hinge plate 556. A pedal is provided at the other end of the second positioning pin 554. A second return spring 557 is sleeved on the first positioning pin 553. The second return spring 557 drives the first positioning pin 553 away from the rotating positioning plate 552. A third return spring 558 is sleeved on the second positioning pin 554. The third return spring 558 drives the second positioning pin 554 away from the hinge plate 556.

[0056] It is worth noting that, in the embodiment of the present invention, the rotation and positioning of the column assembly 400 can be achieved through the rotation and positioning mechanism 550, thereby realizing multi-posture X-ray inspection.

[0057] Specifically, the operator steps on the pedal of the second positioning pin 554, and the lower end of the second positioning pin 554 presses down the hinge plate 556, and the first positioning pin 553 hinged to the middle of the hinge plate 556 moves downward and disengages from the positioning hole 552a. At this time, the slewing bearing 551 is unlocked, and the column assembly 400 can be freely rotated. The pedal of the second positioning pin 554 is released, and the first positioning pin 553 and the second positioning pin 554 are reset under the drive of the second return spring 557 and the third return spring 558, and the first positioning pin 553 is reinserted into the new positioning hole 552a to lock the column assembly 400.

[0058] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
