For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, directional terms such as above, below, up, down, upward, downward, left, right, etc. are used relative to the exemplary embodiments as shown in the figures, with the upward or upper direction toward the top of the corresponding figure, and the downward or lower direction toward the bottom of the corresponding figure.

[0038] In order to solve the above problems, the utility model provides a diagnostic bed plate and a diagnostic bed body. Without changing the existing bed plate manufacturing process, the diagnostic bed plate and the mounting structure are insulated by using physical avoidance and hollow partitions on the bed plate, which helps to reduce the production cost and subsequent maintenance cost of the diagnostic bed plate.

[0039] like Figures 1 to 5 As shown, the diagnostic bed body includes a diagnostic bed plate 100, a trailer 200, a bed frame 300, an insulating layer 400 and connectors, wherein the connectors are not shown in the figure.

[0040] To ensure flexible use of the diagnostic bed, the diagnostic bed in this embodiment further includes a lifting structure 500, wherein the bed frame 300 is installed on the lifting structure 500 and can be driven to rise and fall by the lifting structure 500. The lifting structure 500 can adopt a screw nut pair, hydraulic lifting and other structures.

[0041] The trailer 200 is arranged on the bed frame 300 and can move along the length direction of the bed frame 300. Preferably, the trailer 200 is built into the bed frame 300, and the diagnostic bed board 100 is supported on the bed frame 300 and connected to the trailer 200. When the trailer 200 moves along the length direction of the bed frame 300, it drives the diagnostic bed board 100 to move in and out of the imaging chamber of the scanning device. The trailer 200 can be driven to move in a straight line by a screw nut pair, a linear motor and other structures. In this embodiment, the trailer 200, the bed frame 300 and the lifting structure 500 are all consistent with the existing structure, and will not be described in detail here.

[0042] Usually, the trailer 200 is an electrically driven structure, so in this embodiment, the insulating layer 400 is arranged between the diagnostic bed plate 100 and the trailer 200, so that the insulating layer 400 is isolated between the trailer 200 and the diagnostic bed plate 100. The insulating layer 400 can be made of materials such as engineering plastics, rubber, density board, bakelite, ceramics, fiberglass, etc. The insulating layer 400 can be integrated with the skin 20 of the diagnostic bed plate 100, wherein the skin 20 is described in detail in the following content. The insulating layer 400 can be an integral structure or a block structure, and its specific structure is not limited, as long as it plays the role of isolating the trailer 200 from the diagnostic bed plate 100.

[0043] The trailer 200 is connected to the diagnostic bed plate 100 via the connecting piece (not shown in the figure), and the specific connection method between the two is described in detail in conjunction with the specific structure of the diagnostic bed plate 100 described below.

[0044] The vertical direction in this embodiment is a direction perpendicular to the surface of the filling layer 10, and is also a direction perpendicular to the diagnostic bed plate 100. When the diagnostic bed plate 100 is normally placed, the diagnostic bed plate 100 is substantially horizontally arranged, and the vertical direction corresponds to the vertical direction.

[0045] Please refer to Figures 2 to 5 As shown, the diagnostic bed plate 100 is in a long strip structure and is used to carry a target object.

[0046] The diagnostic bed plate 100 includes: a filling layer 10, a skin 20, and a reinforcement layer 30;

[0047] Please continue to refer to Figure 2 and Figure 3 As shown, a mounting area 11 is provided on the filling layer 10 .

[0048] Installation area 11 is Figure 2 and Figure 3The portion of the middle filling layer 10 located in the frame area is usually also called the tail end or fixed end of the bed board, which is used to be fixedly connected to the horizontal adjustment structure of the bed body (such as the trailer 200) to drive the diagnostic bed board 100 to move horizontally. The installation area 11 is located at one end of the diagnostic bed board 100 along its length direction, so the installation area 11 is also located at one end of the filling layer 10 along its length direction. The trailer 200 is connected to the diagnostic bed board 100 at the position corresponding to the installation area 11 through the connecting piece, so the installation area 11 should ensure sufficient connection strength.

[0049] like Figure 4 As shown, the reinforcement layer 30 is disposed in close contact with the installation area 11 ; the reinforcement layer 30 is disposed to improve the local structural strength of the diagnostic bed plate 100 to meet the local connection requirements with the trailer 200 .

[0050] The filling layer 10 and the reinforcing layer 30 form an inner layer combination, and the skin 20 is wrapped outside the inner layer combination. Figure 4 As shown, the skin 20 constitutes the outermost wrapping layer of the diagnostic bed plate 100, and has the filling layer 10 and the reinforcing layer 30 inside. Most of the inside of the skin 20 is filled with the filling layer 10, and the reinforcing layer 30 only occupies a small part of the space inside the skin 20.

[0051] Please continue to refer to Figure 4 As shown, the filling layer 10 is located at Figure 4 The right end position in the figure corresponds to the installation area 11, the reinforcement layer 30 is attached to the area, and the rest of the diagnostic bed plate 100 is the imaging area. To ensure a good imaging effect in the imaging area, the skin 20 and the filling layer 10 should have little effect on the imaging.

[0052] In this embodiment, the skin 20 is made of commonly used carbon fiber material, and the filling layer 10 is preferably made of insulating foam filling material such as polymethacrylimide PMI, polyethylene PE, polyethylene terephthalate PET, etc. The reinforcement layer 30 is preferably made of glass fiber reinforced plastic insulating material.

[0053] In other alternative embodiments, the filling layer 10 and the reinforcement layer 30 may be made of other insulating materials adaptively selected based on usage requirements.

[0054] Please continue to refer to Figure 3 as well as Figure 5 and Figure 6 As shown, the reinforcing layer 30 is arranged along the vertical direction and away from the side of the filling layer 10 (i.e. Figure 3 , Figure 5 as well as Figure 6A connection structure 31 is provided on the lower surface of the middle reinforcement layer 30 , and a through hole 21 is provided on the skin 20 , which exposes the connection structure 31 to ensure that the connecting parts on the trailer 200 can pass through the through hole 21 and connect to the connection structure 31 .

[0055] In order to ensure sufficient connection strength, in this embodiment, the connection structure 31 is provided with a plurality of. Figure 3 As shown, in this embodiment, each connection structure 31 corresponds to a through hole 21, wherein the through holes are provided in two rows, each row including six through holes 21 arranged along the length of the diagnostic bed plate 100, a total of twelve through holes 21 are provided, and twelve connection structures 31 are provided accordingly. The trailer 200 is connected to the connection structure 31 through the connection member (not shown in the figure), so that the diagnostic bed plate 100 can be reliably installed on the trailer 200.

[0056] Please refer to Figure 5 and Figure 6 As shown, Figure 5 and Figure 6 Only a portion of the diagnostic bed plate 100 is shown, wherein the portion of the skin layer 20 located on the upper end surface of the diagnostic bed plate 100 and the filling layer 10 are not shown.

[0057] The connection structure 31 includes a connection sleeve 311, and the reinforcement layer 30 is vertically away from the side of the filling layer 10 (i.e. Figure 3 , Figure 5 as well as Figure 6 The lower surface of the middle reinforcing layer 30 is provided with a mounting hole 32, and the connecting sleeve 311 is installed in the mounting hole 32. The connecting sleeve 311 is a cylindrical sleeve, and the connecting sleeve 311 can be fixed in the mounting hole 32 by interference fit, bonding, etc. In this embodiment, since the reinforcing layer 30 is made of insulating material, there is no limitation on whether the connecting sleeve 311 is insulating. The connecting sleeve 311 can be made of metal materials such as iron, copper, aluminum, steel, alloy, etc. When the reinforcing layer 30 is made of non-insulating material, the connecting sleeve 311 is preferably made of insulating material, such as commonly used engineering plastics, rubber, density board, bakelite, ceramics, fiberglass, etc.

[0058] In this embodiment, since a plurality of connection structures 31 are provided, a plurality of mounting holes 32 corresponding to the connection structures 31 are formed on the reinforcement layer 30 .

[0059] Since multiple connection structures 31 are provided, the trailer 200 and the diagnostic bed plate 100 are connected via multiple connectors, and the connection requirements of the two can be met by multiple connectors. Therefore, the reinforcement layer 30 can be set to be relatively thin. Please continue to refer to Figure 4 As shown, the reinforcing layer 30 is embedded in the first side a of the filling layer 10, and after the reinforcing layer 30 is embedded in the filling layer 10, it is flush with the surface of the filling layer 10 ( Figure 4 The first side a is the lower surface of the filling layer 10, and the lower surface of the reinforcing layer 30 is flush with the lower surface of the filling layer 10. Therefore, the skin of the diagnostic bed plate 100 located on the lower surface is relatively flat and has no protrusions, which improves the aesthetics of the diagnostic bed plate 100 and helps simplify the manufacturing process of the diagnostic bed plate 100. At the same time, the overall size of the diagnostic bed plate 100 is relatively thin, which facilitates the installation of the diagnostic bed plate 100.

[0060] In this embodiment, the through hole 21 and the mounting hole 32 are circular holes adapted to the connecting sleeve 311 .

[0061] In other alternative embodiments, the connection structure 31 may also be integrated into the reinforcement layer 30. When the structural strength of the reinforcement layer 30 meets its local connection requirements, the connection structure 31 may be a threaded hole directly opened on the reinforcement layer 30. Of course, the connection structure 31 may also be other structures, and the specific structural form of the connection structure 31 may be adaptively adjusted based on the connection form between the connector (not shown in the figure) and the connection structure 31. For example, the two may be snap-fitted, welded or other known connection forms, and the connection structure 31 may adaptively adjust the corresponding structure. Accordingly, the shapes of the through hole 21 and the mounting hole 32 may also be adaptively changed based on the specific structure of the connection structure 31.

[0062] In other alternative embodiments, the number and location of the connection structures 31 and the mounting holes 32 can be adaptively adjusted based on actual connection strength requirements.

[0063] Please continue to refer to Figure 5 As shown, the connecting member (not shown in the figure) can pass through the connecting hole 201 of the trailer 200 and the through hole 21 on the skin 20 and then be connected to the connecting sleeve 311. In this embodiment, the connecting sleeve 311 has an internal thread, and the connecting member can be a threaded connecting member such as a screw or a bolt, which passes through the connecting hole 201 and is screwed into the connecting sleeve 311 and is threadedly connected to the connecting sleeve 311.

[0064] In other alternative embodiments, the connecting member may also be connected to the connecting sleeve 311 by snap-fitting, interference fitting or other known methods.

[0065] like Figure 5 and Figure 6 As shown, when the connecting piece (not shown) passes through the connecting hole 201 of the trailer 200, the connecting piece (not shown) will contact the trailer 200, and the connecting piece will be connected to the connecting sleeve 311. Therefore, if the connecting piece and the connecting sleeve 311 are both made of conductive materials, the trailer 200 is connected to the connecting sleeve 311. In this embodiment, the filling layer 10 is made of insulating material, so the connecting sleeve 311 and the skin 20 are isolated by the filling layer 10.

[0066] In order to ensure that the connector does not contact the skin 20 when passing through the through hole 21 on the skin 20, there is a gap between the connector (not shown in the figure) and the inner wall of the through hole 21 in this embodiment, and the air between the connector and the inner wall of the through hole 21 serves as an insulating medium. Further, the aperture of the through hole 21 is larger than the aperture of the mounting hole 32; and along the vertical projection, the mounting hole 32 is located inside the through hole 21. Preferably, the aperture of the through hole 21 differs from the aperture of the mounting hole 32 by more than 10 mm, so as to ensure that the gap between the connector and the inner wall of the through hole 21 meets the creepage distance requirement as much as possible. In addition, the through hole 21 and the mounting hole 32 are coaxially opened. At this time, the through hole 21, the mounting hole 32, the connecting sleeve 311 and the connector connected to the connecting sleeve 311 are all coaxially arranged, so as to ensure that the gap between the outer peripheral surface of the connector (not shown in the figure) and the inner wall of the through hole 21 remains uniform.

[0067] Alternatively, the difference between the aperture of the through hole 21 and the aperture of the mounting hole 32 is less than 10 mm. In this case, an insulating medium such as rubber or plastic is provided between the connector and the inner wall of the through hole 21. The insulating medium is filled to isolate the connector (not shown in the figure) from the inner wall of the through hole 21, so that there is no conduction between the connector and the skin 20.

[0068] In order to prevent the connector (not shown in the figure) from contacting the skin 20, an insulating layer may be locally added to the lower surface of the skin 20 corresponding to the installation area 11. The insulating layer extends to the inner wall of the through hole 21 to isolate the connector from the skin 20.

[0069] Please continue to refer to Figure 6 As shown, in order to further ensure the insulation performance, the first end of the connecting sleeve 311 away from the filling layer 10 along the vertical direction is located inside the mounting hole 32, and the first end corresponds to Figure 6 The lower end of the middle connecting sleeve 311, Figure 6 The upper end of the middle connecting sleeve 311 serves as the second end of the connecting sleeve 311. The first end has a set distance from the open end of the mounting hole 32, and the set distance is the vertical distance between the first end and the open end of the mounting hole 32. Based on the creepage requirements and the connection structure, the set distance is preferably 3 to 10 mm, for example, the set distance can be set to 4 mm, 5 mm or 6 mm. The set distance can be adaptively adjusted based on actual needs. There is a height difference between the lower end surface of the connecting sleeve 311 and the lower surface of the reinforcement layer 30, so that the connecting sleeve 311 is as far away from the skin 10 as possible to achieve a better insulation isolation effect.

[0070] In other alternative embodiments, the connector (not shown in the figure) may also be made of insulating material. In this case, the trailer 200 and the connecting sleeve 311 will not be connected through the connector (not shown in the figure) to further improve the insulation effect.

[0071] It should be noted that the above content provides several implementation methods of the diagnostic bed board, and the technical features in each implementation method are not strictly independent, and the technical features in each implementation method can also be used interchangeably.

[0072] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0073] The above description is only a description of the preferred embodiment of the utility model, and is not any limitation on the scope of the utility model. Any changes and modifications made by ordinary technicians in the field of the utility model based on the above disclosure shall fall within the scope of protection of the claims.
