Description

Flexible panel supporting structure, enclosure structure and flexible X-ray detection device
Technical Field
The application relates to the technical field of X-ray detection, in particular to a flexible panel supporting structure, a surrounding shell structure and a flexible X-ray detection device.
Background
The X-ray detection utilizes the penetration, differential absorption, sensitization and fluorescence of X-rays to the object, and the density distribution information of each part of the object is projected onto an X-ray acquisition and imaging device to form corresponding images, so that the internal structure and condition of the object are observed. It can be widely applied to the fields of medical treatment, industrial nondestructive detection and the like.
Conventional X-ray flat panel detectors for X-ray inspection are generally flat, and due to their inflexible detection panels such as glass TFTs (Thin Film Transistor, i.e. thin film field effect transistors) and rigid structural designs, when they detect objects to be detected having a certain curvature, such as CBCT (Cone beam CT), nondestructive detection of pipes, etc., used in the medical field, the rest will obtain distorted images except for the area where the detection device is in tangential contact with the objects to be detected. The larger the curvature of the object to be measured is, the more serious the image distortion is, thereby bringing difficulty to the evaluation and judgment of the image.
There is great progress in the development of flexible sensors, which can be easily shaped to accommodate "non-planar" scenes. In the field of X-ray detection, in order to adapt to the curvature of an object to be detected and reduce the problem of image distortion, a flexible X-ray detection panel has also appeared, which can bend to a certain extent according to the curvature of the surface of the object to be detected, thereby reducing the distortion phenomenon and improving the image quality.
In the prior art, two ends of a general flexible X-ray detection panel are fixed, and bending force is applied to the two ends of the flexible X-ray detection panel, so that the middle position of the flexible X-ray detection panel is bent first, and parts on two sides of the middle position are bent along with the middle position to adapt to the curvature of an object to be detected. However, because the two ends of the flexible X-ray detection panel are fixed, the length of the flexible X-ray detection panel when being bent changes, a larger tearing acting force can be generated on the flexible X-ray detection panel, and the flexible X-ray detection panel is seriously possibly torn, so that the product is damaged and fails.

The components of the embodiments of the present application generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the application, as presented in the figures, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the present application, the directions of "front", "rear", "left", "right", "upper", "lower", etc. are shown in the drawings, and these directional terms are merely used to clearly indicate the relative positional relationship between the components in describing the present application, and do not constitute an absolute limitation on the positions of the components in the present application.
As shown in fig. 1 and 2, the present embodiment provides a flexible panel support structure including two end blocks 10, a flexible upper cover plate 20, a plurality of ribs 30, and a flexible middle plate 40, which are disposed in parallel at a predetermined distance. The direction in which the line connecting the center of one of the end blocks 10 to the center of the other end block 10 is located is defined as the left-right direction.
Wherein, the left and right ends of the upper cover plate 20 are respectively fixed on the two end blocks 10. All the ribs 30 are disposed under the upper cover plate 20, and all the ribs 30 are arranged parallel to each other with a predetermined distance therebetween between the two end blocks 10, each rib 30 extending in the front-rear direction; the end portions of the front and rear ends of each rib 30 are fixedly connected to the front and rear edges of the lower surface of the upper cover plate 20, respectively, and a predetermined installation gap is formed between the upper surface of the portion between the front and rear end portions of all the ribs 30 and the lower surface of the upper cover plate 20. The intermediate plate 40 is disposed in a predetermined installation gap between the upper cover plate 20 and the rib 30. When the intermediate plate 40 is flat, the left and right ends of the intermediate plate 40 extend to the two end blocks 10.
The left and right ends of the intermediate plate 40 are referred to as a first end and a second end. Wherein, only the first end of the intermediate plate 40 is fixedly connected with the corresponding end block 10, and other positions of the intermediate plate 40 body are not fixed except the first end. Alternatively, any one of the ribs 30 is fixedly attached to the lower surface between the first and second ends of the intermediate plate 40, and the intermediate plate 40 is not fixed in any other position than the position fixedly attached to the rib 30. The upper surface of the intermediate plate 40 is used for gluing the flexible panel.
It should be noted that, in the flexible panel supporting structure provided in this embodiment, when the first end of the middle plate 40 is fixedly connected with the corresponding end block 10, or when any one of the ribs 30 is fixedly connected with the lower surface between the first end and the second end of the middle plate 40, the fixed connection may be achieved by adopting the cooperation of screw threaded holes, or some fastening structures may be used. The specific connection structure of the intermediate plate 40 to the end block 10 or to the ribs 30 is not shown in the drawings of this embodiment, and can be flexibly selected by those skilled in the art according to the actual circumstances.
In a preferred embodiment, the first end of the intermediate plate 40 is preferably fixedly connected to the corresponding end block 10, the other positions not being fixed.
With the flexible X-ray detection panel 100 as the flexible panel, the flexible panel support structure of the present embodiment, in use, as shown in fig. 2, glues the flexible X-ray detection panel 100 to the upper surface of the intermediate plate 40 and places the same in the predetermined installation gap between the upper cover plate 20 and all the ribs 30.
When the flexible X-ray detection panel 100 is bent to adapt to an object to be detected, the end blocks 10 can be used as force application ends, the upper cover plate 20 starts to bend upwards by applying force to the two end blocks 10, and then the ribs 30 are driven to generate mutual separation and bending actions, the upper surfaces of the ribs 30 form a curved surface similar to the bending shape of the upper cover plate 20, and then the middle plate 40 between the upper cover plate 20 and the ribs 30 is driven to bend, and the flexible X-ray detection panel 100 also bends along with the bending of the middle plate 40 due to the fact that the upper surface of the middle plate 40 is adhered with the flexible X-ray detection panel 100.
Meanwhile, since only one end of the intermediate plate 40 is fixed to the end block or the body of the intermediate plate 40 is fixed to the upper surface of one of the ribs 30, the intermediate plate 40 can be naturally slid and bent adaptively in a predetermined installation gap between the upper cover plate 20 and the rib 30, without being affected by a tearing force, except for the fixed position, when being bent. Correspondingly, the flexible X-ray detection panel 100 glued to the intermediate plate 40 can naturally bend and slide the same as the intermediate plate 40, so that the flexible X-ray detection panel 100 does not receive a tearing force in the left-right direction, and thus a tearing phenomenon does not occur basically, the flexible X-ray detection panel 100 is effectively protected, and the durability and the service life of the product are improved.
In addition, the flexible panel support structure of the present embodiment guides the bending of the intermediate plate 40 instead of directly forcing the flexible X-ray detection panel 100 to bend, so that friction of the upper surface of the rib 30 against the lower surface of the flexible X-ray detection panel 100 can be eliminated, which is beneficial for protecting the flexible X-ray detection panel 100.
In the present embodiment, as shown in fig. 3 and 4, a plurality of protrusions 31 are respectively connected to the left and right sides of each rib 30 in the extending direction, and the plurality of protrusions 31 located on the same side of the rib 30 in the extending direction are parallel to each other and spaced apart from each other by a predetermined distance, and the upper surfaces of the protrusions 31 are level with the upper surfaces of the ribs 30. The number of the projections 31 on the adjacent side of the adjacent rib 30 is uniform and the positions are in one-to-one correspondence. When the upper cover plate 20 is flattened, end faces of the protruding portions 31 on adjacent sides of all the adjacent ribs 30 are close to or contact with each other, and all the protruding portions 31 and all the ribs 30 are staggered with each other to form a grid structure, so that a better supporting force is given to the intermediate plate 40, the bending of the intermediate plate 40 is smoother and more natural, and further, the bending change of the flexible X-ray detection panel 100 is also more natural.
In the present embodiment, as shown in fig. 4, the number of the convex portions 31 on the left and right sides of each rib 30 is the same and the extending directions are coincident, and the number of the convex portions 31 of any adjacent two ribs 30 is the same and the extending directions are coincident.
In this embodiment, as shown in fig. 3, the front and rear ends of each rib 30 in the extending direction are respectively provided with an installation part 301, an attaching part 302 is arranged between the two installation parts 301, and the upper surface of the installation part 301 is higher than the upper surface of the attaching part 302; the upper surfaces of the mounting portions 301 at the front and rear ends of each rib 30 are fixedly connected to the lower surface of the upper cover plate 20, and a predetermined mounting gap for accommodating the intermediate plate 40 and the flexible panel is formed between the lower surface of the upper cover plate 20 and the upper surfaces of the fitting portions 302 of all the ribs 30.
In this embodiment, as shown in fig. 5, the flexible panel support structure further includes a bendable lower cover plate 50, and the lower cover plate 50 is disposed below the ribs 30. The underside of each end block 10 is provided with a chute 11 towards the other end block 10; the left and right ends of the lower cover plate 50 are respectively inserted into the sliding grooves 11 of the two end blocks 10 to form a sliding fit; the left and right ends of the lower cover plate 50 are restrained from sliding in the slide grooves 11 of the two end blocks 10.
When the upper cover plate 20 is bent upwards, the lower cover plate 50 is bent upwards, and at the moment, the left and right ends of the lower cover plate 50 slide out of the sliding grooves 11 of the left and right end blocks 10 by a certain distance so as to adapt to the change of the length after bending, and realize bending length compensation. When the upper cover plate 20 is restored to be flat, the left and right ends of the lower cover plate 50 slowly slide into the sliding grooves 11 of the left and right end blocks 10 to adapt to the shortened length change after bending, so as to realize the length compensation in the process of restoring to be flat.
In the present embodiment, as shown in fig. 6, the maximum sliding distance D of the left end of the lower cover plate 50 in the slide groove 11 of the left end block 10 1 The maximum sliding distance of the right end of the lower cover plate 50 in the sliding groove 11 of the right end block 10 is D 2 The maximum total sliding distance is d=d 1 +D 2 Then
Wherein L is the total length from the left end to the right end of the upper cover plate 20, R min For the radius of curvature of the upper cover plate 20 corresponding to the flexible panel between the upper cover plate 20 and all of the ribs 30 reaching the desired minimum working radius of curvature, d is the distance between the upper cover plate 20 and the lower cover plate 50. In one embodiment, D may be made 1 ＝D 2 。
Because the sliding distance of the left and right ends of the lower cover plate 50 in the sliding grooves 11 of the two end blocks 10 is limited. When the upper cover plate 20 is flattened, the left and right ends of the lower cover plate 50 are restricted from further sliding into the sliding grooves 11 of the two end blocks 10, and simultaneously, since the end faces of the end portions of the protrusions 31 of the adjacent sides of all the adjacent ribs 30 are close to or in contact with each other when flattened, the downward reverse bending of the upper cover plate 20 can be restrained and hindered, and further, the downward reverse bending of the intermediate plate 40 and the flexible X-ray detection panel 100 can also be restrained and hindered, thereby substantially eliminating the damage caused by the reverse bending. When the upper cover plate 20 is bent upward in a flat direction and reaches a desired minimum radius of curvature of the flexible X-ray detection panel 100, the left and right ends of the corresponding lower cover plate 50 slide out to the extreme edges of the slide grooves 11 of the two end blocks 10 and cannot further slide out, thereby limiting further bending of the upper cover plate 20 and further bending of the intermediate plate 40 and the flexible X-ray detection panel 100, thereby limiting the radius of curvature of the flexible X-ray detection panel 100 within a safe range to prevent damage caused by excessive bending.
In the present embodiment, as shown in fig. 7 and 8, both the left and right ends of the lower cover plate 50 are provided with a limit groove 51 extending in the left-right direction, and limit posts 12 are provided in the slide grooves 11 of the two end blocks 10, the limit posts 12 penetrating into the limit groove 51; the relative sliding distance between the left limit groove 51 of the lower cover plate 50 and the corresponding limit post 12 on the left side is equal to D 1 . The relative sliding distance between the limit groove 51 on the right side of the lower cover plate 50 and the limit post 12 corresponding to the right side is equal to D 2 . When the upper cover plate 20 is flat, the left limit post 12 slides relatively to the rightmost end of the limit groove 51 on the left side of the lower cover plate 50, and the right limit post 12 slides relatively to the leftmost end of the limit groove 51 on the right side of the lower cover plate 50. When the upper cover 20 is bent upward to achieve a desired minimum radius of curvature of the flexible panel between the upper cover 20 and the ribs 30, the left side stopper post 12 slides relatively to the leftmost end of the left side stopper groove 51 of the lower cover 50, and the right side stopper post 12 slides relatively to the rightmost end of the right side stopper groove 51 of the lower cover 50.
As shown in fig. 9 and 10, the present embodiment further provides a flexible panel enclosure structure, including the flexible panel support structure in the foregoing solution, and further including a flexible edge strip structure 60. The front and rear edges of the lower surface of the upper cover plate 20 and the front and rear edges of the upper surface of the lower cover plate 50 form edge gaps respectively, flexible edge strip structures 60 are arranged in the edge gaps, two ends of each flexible edge strip structure 60 extend until the two ends of each flexible edge strip structure are in contact with the two end blocks 10, the upper and lower surfaces of each flexible edge strip structure 60 are respectively attached to the upper cover plate 20 and the lower cover plate 50 all the time, and the upper surfaces of the flexible edge strip structures 60 are fixedly connected with the lower surface of the upper cover plate 20.
In this embodiment, the upper cover plate 20, the two end blocks 10, the lower cover plate 50 and the flexible edge strip structure 60 enclose a relatively closed space for wrapping the flexible panel and can maintain a relatively tight seal in bending, thus isolating most of the dust from contact with the flexible panel. Particularly, when the flexible panel is the flexible X-ray detection panel 100, the relatively closed space enclosed by the upper cover plate 20, the two end blocks 10, the lower cover plate 50 and the flexible edge strip structure 60 reduces the circuit failure rate caused by dust or impurities entering, thereby effectively protecting the flexible X-ray detection panel 100 and stabilizing the imaging quality.
As shown in fig. 2, 5 and 11, the present embodiment further provides a flexible X-ray detection apparatus, which includes the flexible panel support structure in the foregoing aspect, or includes the flexible panel enclosure structure in the foregoing aspect. Also included is a flexible X-ray detection panel 100 disposed in a predetermined mounting gap between the upper cover plate 20 and the ribs 30, the flexible X-ray detection panel 100 being attached and glued to the upper surface of the intermediate plate 40.
The above is only a preferred embodiment of the present application, and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
