[0001] The present disclosure relates to the technical field of parts detection, and in particular to a detection platform. Background Art

[0002] In a vehicle, the body is often connected to the subframe through a fixing plate. The middle of the fixing plate is raised relative to the flange edge and is sleeved with a nut seat. The body is bolted to the chassis by sleeved on the nut seat. Before and after the nut seat is sleeved on the fixing plate, it is necessary to detect whether the fixing plate is deformed to confirm whether the fixing plate and the connection between the fixing plate and the nut seat meet the use standards.

[0003] In the related art, before the nut seat is sleeved on the fixed plate, the flange plate needs to be fitted with the inspection table to detect whether the fixed plate is deformed. After the nut seat is sleeved on the fixed plate, the nut seat needs to be fitted with the inspection table to detect whether the fixed plate is deformed. Therefore, before and after the nut seat is sleeved on the fixed plate, two sets of inspection tables need to be used to respectively fit the flange edge of the fixed plate and the nut seat with the inspection table to detect the fixed plate.

[0004] However, using two sets of testing stations will increase the testing cost. Summary of the invention

[0010] In some possible implementations, the pressing portion of the pressing block mechanism can move toward or away from the first positioning structure.

[0011] In some possible implementations, the testing platform further includes a clamping mechanism, which includes a second fixed portion and a clamping portion connected to each other, the second fixed portion is fixed to the base, and the clamping portion is used to clamp on the outer side of the nut seat to fix the nut seat.

[0012] In some possible implementations, the first region has a plurality of first positioning holes, and the plurality of first positioning holes are used to be opposite to the second positioning holes on the flange edge so as to position the flange edge.

[0013] In some possible implementations, there is a gap between the edge of the flange and the detection body, and the detection platform also includes a stop pin, which is detachably fixed to the base, and the first end and the second end of the stop pin have different outer diameters, so as to judge whether the flatness of the flange edge is qualified based on whether the first end and the second end can be inserted into the gap.

Therefore, the state of the detection bench can be switched by only installing or disassembling the first positioning structure, so as to meet the detection requirements of the fixed plate before and after the nut seat is sleeved on the fixed plate, respectively, without the need to use two sets of detection benches, thereby reducing the detection cost.

[0020] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0021] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] In a vehicle, the vehicle body is often connected to the subframe via a fixing plate 200. Figure 3 As shown, the fixing plate 200 includes a flange 201 and a raised portion 202 raised relative to the flange 201. The flange 201 half surrounds the raised portion 202. The raised portion 202 has a through hole 2021 in the middle. Figure 4 , Figure 5 As shown, when the vehicle is assembled, the nut seat 300 will first pass through the through hole 2021 and be fixedly connected to the fixing plate 200 by, for example but not limited to, welding. Then, the fixing plate 200 will be connected to the subframe by bolts, and the flange edge 201 will be welded to the vehicle body. Then, the screw will pass through the nut seat 300 to achieve a fixed connection between the vehicle body and the chassis.

[0023] During the production process of the vehicle, before and after the nut seat 300 is sleeved on the fixing plate 200 , the fixing plate 200 needs to be inspected to confirm whether the fixing plate 200 meets the use standard.

[0024] In the related art, before the nut seat 300 is sleeved on the fixed plate 200, the flange edge 201 of the fixed plate 200 is used as the detection reference. At this time, the flange edge 201 of the fixed plate 200 needs to be fitted with the detection platform, and the raised portion 202 of the fixed plate 200 needs to be spaced apart from the detection platform. After the nut seat 300 is sleeved on the fixed plate 200, the nut seat 300 is used as the detection reference. At this time, the nut seat 300 needs to be fitted with the detection platform, and the flange edge 201 needs to be spaced apart from the detection platform. Therefore, before and after the nut seat 300 is sleeved on the fixed plate 200, two sets of detection platforms need to be used to respectively fit the flange edge 201 of the fixed plate 200 and the nut seat 300 with the detection platform, so as to detect the fixed plate 200.

[0025] However, using two sets of testing stations will increase the testing cost.

[0026] In order to solve the above technical problems, the present disclosure provides a detection platform, combined with Figure 1 , Figure 2 and Figure 6As shown, the detection platform includes a base 0, a detection body 1, a first positioning structure 2 and a second positioning structure 3. The detection body 1 is fixed to the base 0 and includes a first area 11 and a second area 12 connected to each other. The first area 11 semi-surrounds the second area 12. The first positioning structure 2 is detachably fixed to the first area 11 and is used to fit with the flange edge 201 of the fixed plate 200 to be detected, so as to support the flange edge 201 so that the raised portion 202 of the fixed plate 200 does not contact the second positioning structure 3. The second positioning structure 3 is fixed to the second area 12 and is lower than the first positioning structure 2. The second positioning structure 3 is used to fit with the side of the nut seat 300 to be detected which is sleeved on the fixed plate 200 and is away from the fixed plate 200, so as to support the nut seat 300 and leave the flange edge 201 suspended.

[0027] In the embodiment of the present disclosure, the detection platform has a first state and a second state. The first state is a state in which the first positioning structure 2 is fixed to the first area 11, and the second state is a state in which the first positioning structure 2 is disassembled. In the first state, Figure 1 As shown, the fixing plate 200 that is not assembled with the nut seat 300 can be inspected, wherein the flange edge 201 of the fixing plate 200 can be attached to the inspection table through the first positioning structure 2 to meet the inspection requirements; in the second state, as Figure 6 As shown, the whole structure connected with the nut seat 300 and the fixing plate 200 can be inspected, wherein the nut seat 300 can be fitted with the second positioning structure 3 to meet the inspection requirements. Therefore, only the first positioning structure 2 needs to be installed or removed to switch the state of the inspection table, so as to meet the inspection requirements of the fixing plate 200 before and after the nut seat 300 is sleeved on the fixing plate 200, without using two sets of inspection tables, thereby reducing the inspection cost.

[0028] The first area 11 is the area corresponding to the detection body 1 and the flange edge 201 , and the second area 12 is the area corresponding to the detection body 1 and the nut seat 300 to be detected which is sleeved on the fixing plate 200 .

[0029] Among them, before the nut seat 300 is sleeved on the fixed plate 200, the first positioning structure 2 can be installed on the first area 11. At this time, the flange edge 201 of the fixed plate 200 is fitted with the detection table through the first positioning structure 2. At the same time, there is a gap between the raised portion 202 of the fixed plate 200 and the second positioning structure 3, thereby preventing the raised portion 202 from directly contacting the second positioning structure 3, causing interference with the fit between the flange edge 201 and the first positioning structure 2, thereby causing inaccurate detection results.

[0030] Among them, after the nut seat 300 is sleeved on the fixed plate 200, the first positioning structure 2 can be removed from the first area 11. At this time, the nut seat 300 can be fitted with the detection table through the second positioning structure 3. At the same time, there is a gap between the flange edge 201 of the fixed plate 200 and the detection body 1, so as to prevent the flange edge 201 and the detection body 1 from interfering with the fit between the nut seat 300 and the second positioning structure 3, thereby causing inaccurate detection results.

[0031] Among them, Figure 1 , Figure 6 As shown, when the fixing plate 200 is fixed, there is a gap between the edge of the fixing plate 200 and the detection body 1, and the size of the gap can be used as a standard for detecting whether the fixing plate 200 is deformed. When the fixing plate 200 meets the standard, the size of the gap is relatively uniform, and when the size of the gap is within a certain range, the fixing plate 200 can be considered qualified, otherwise, the fixing plate 200 is unqualified.

[0032] In the disclosed embodiment, when the fixing plate 200 is inspected, it is mainly inspected by a digital inspection instrument to detect the sizes of the above-mentioned intervals and record them. The inspection table mainly plays the role of fixing and positioning the fixing plate 200.

[0033] The second positioning structure 3 is in the shape of a circular opening groove so as to fit with the nut of the nut seat 300 .

[0034] like Figure 2 As shown, the middle part of the second positioning structure 3 has a detection hole 31, and the detection hole 31 is used to be opposite to the through hole 2021. The detection platform also includes a detection pin 8, and the detection pin 8 includes a plug-in portion 81 and a flat plate structure 82. When the detection platform is in the first state, the plug-in portion 81 is inserted into the through hole 2021 and the detection hole 31 in sequence. After the plug-in portion 81 is inserted into the through hole 2021 and the detection hole 31, there is a gap between the flat plate structure 82 and the protrusion 202, and the gap is used as a standard for evaluating whether the protrusion 202 meets the requirements. If the protrusion 202 is not deformed, the spacing between each part of the flat plate structure 82 and the protrusion 202 should be basically equal, and it can at least be controlled within a reasonable range. If the protrusion 202 is deformed, the protrusion 202 is partially tilted or concave, which will cause the distance between the protrusion 202 and the flat plate structure 82 to be too small or too large.

[0035] In this way, by detecting the gap between the flat structure 82 and the raised portion 202 , the flatness data of the raised portion 202 can be obtained more conveniently.

[0036] In some embodiments, Figure 1As shown, the inspection platform further comprises at least three reference blocks 9, wherein at least three reference blocks 9 are not collinear.

[0037] Thus, when the fixing plate 200 is placed on the inspection table and inspected, the three non-collinear reference blocks 9 can be used as the reference of the inspection table and a coordinate system can be established, so that the digital inspection of the fixing plate 200 can be realized more quickly.

[0038] Optionally, three non-collinear reference blocks 9 are located at three vertex corners of the base 0 .

[0039] In some embodiments, the first positioning structure 2 is a gasket.

[0040] In this way, by placing the gasket on the first area 11, the detection platform can be switched to the first state, and by removing the gasket from the first area 11, the detection platform can be switched to the second state. The placement and removal of the gasket are relatively fast and convenient. Therefore, the switching of the detection platform state can be achieved in a more convenient way, thereby greatly improving the detection efficiency of the fixed plate 200.

[0041] Optionally, the gasket may be made of, for example but not limited to, rubber material.

[0042] In some embodiments, Figure 1 As shown, the testing platform includes a plurality of first positioning structures 2 , each of which is in the shape of a screw, which is inserted into the first area 11 , and a nut is used to fit with the flange edge 201 .

[0043] In this way, by inserting the screw-shaped first positioning structure 2 into the first area 11, the detection platform can be switched to the first state, and by removing the screw-shaped first positioning structure 2 from the first area 11, the detection platform can be switched to the second state, and the placement and removal of the gasket are relatively fast and convenient, so that the switching of the detection platform state can be achieved in a relatively convenient way, thereby greatly improving the detection efficiency of the fixed plate 200. In addition, by inserting the first positioning structure 2 into the first area 11, the installation of the first positioning structure 2 can also be positioned, thereby preventing the first positioning structure 2 from shifting during the installation process, and then ensuring that the fitting position of the contact surface between the first positioning structure 2 and the flange edge 201 remains unchanged, so as to ensure the accuracy of the detection of the fixed plate 200.

[0044] Optionally, the outer side of the first positioning structure 2 may have threads or may not have threads, which is not limited in the embodiment of the present disclosure.

[0045] In some embodiments, Figure 1As shown, the testing platform further includes a pressing mechanism 4 , which includes a first fixing portion 41 and a pressing portion 42 connected to each other. The first fixing portion 41 is fixed to the base 0 , and the pressing portion 42 is used to press the flange edge 201 tightly onto the first positioning structure 2 .

[0046] In this way, in the first state, after the flange edge 201 is fitted with the first positioning structure 2, the flange edge 201 can be pressed tightly against the first positioning structure 2 through the extrusion portion 42 of the block pressing mechanism 4, so that the position of the fixed plate 200 can be fixed by the extrusion portion 42 to prevent the fixed plate 200 from shifting when being inspected under a low external force, thereby ensuring that the inspection of the fixed plate 200 can be carried out stably.

[0047] Optionally, the extrusion part 42 may be, for example but not limited to, a rubber block, wherein the rubber material has good elasticity, and the use of the rubber block to press the flange 201 can also prevent the flange 201 from being deformed under the external force of the extrusion part 42 .

[0048] Optionally, the pressure of the extrusion part 42 on the flange 201 is controlled to be 4N-6N. In this way, the extrusion part 42 can prevent the extrusion force on the flange 201 from being too large, thereby causing the fixing plate 200 to deform, while ensuring the fixing effect of the extrusion part 42 on the flange 201.

[0049] In some embodiments, Figure 1 As shown, the testing platform includes a plurality of pressing mechanisms 4 , and the plurality of pressing mechanisms 4 are distributed around the testing body 1 .

[0050] In this way, in the first state, after the flange edge 201 is fitted with the first positioning structure 2, the extrusion parts 42 of the multiple pressing block mechanisms 4 can be used to squeeze different positions of the flange edge 201 along the circumference of the second positioning structure 3 to ensure the effect of fixing the fixed plate 200, thereby further reducing the possibility of the fixed plate 200 being offset when the fixed plate 200 is detected, and further ensuring that the detection of the fixed plate 200 can be carried out stably.

[0051] In some embodiments, the test bench includes a plurality of first positioning structures 2, and the plurality of first positioning structures 2 are in the shape of screws, and a portion of the flange 201 will fit with the nut of the first positioning structure 2, while the other positions of the flange 201 will be suspended. The number of the block pressing mechanisms 4 corresponds to the number of the first positioning structures 2, and when the flange 201 is pressed by the block pressing mechanisms 4, each block pressing mechanism 4 is pressed on a side of the flange 201 away from the first positioning structure 2, so that the first positioning structure 2 can support the pressing portion 42 of the block pressing mechanism 4 to prevent the flange 201 from being deformed when the pressing portion 42 presses the flange 201.

[0052] Optionally, the first fixing portion 41 and the detection body 1 are formed integrally.

[0053] In some embodiments, in combination Figure 1 , Figure 6 As shown, the pressing portion 42 of the pressing mechanism 4 can move toward or away from the first positioning structure 2 .

[0054] Thus, in the first state, before the flange edge 201 is fitted with the first positioning structure 2, the extrusion part 42 is moved to a position away from the first positioning structure 2 to prevent the extrusion part 42 from obstructing the fitting of the flange edge 201 of the fixing plate 200 with the first positioning structure 2; after the flange edge 201 is fitted with the first positioning structure 2, the extrusion part 42 is moved to a position close to the first positioning structure 2 to squeeze and fix the flange edge 201 of the fixing plate 200 through the extrusion part 42. Thus, by moving the extrusion part 42 to a position close to or away from the first positioning structure 2, the fixing effect of the extrusion part 42 on the flange edge 201 can be ensured while preventing the extrusion part 42 from interfering with the fitting of the flange edge 201 with the first positioning structure 2.

[0055] The block pressing mechanism 4 further includes a first locking rod 43 and a first rotating arm 44, one end of the first rotating arm 44 is hinged to the first fixed part 41, and the other end is connected to the extrusion part 42, so that the extrusion part 42 can be moved by the rotation of the first rotating arm 44. The first locking rod 43 is hinged to the first fixed part 41, and has a first locking state and a first relaxing state. When the first locking rod 43 is in the first locking state, part of the first locking rod 43 abuts against the first rotating arm 44, so that the rotation of the first rotating arm 44 can be restricted. When the first locking rod 43 is in the first relaxing state, the first locking rod 43 releases the first rotating arm 44, and the first rotating arm 44 can rotate freely. Therefore, when the extrusion part 42 extrudes the flange edge 201, the first rotating arm 44 can be locked by the first locking rod 43, so that the extrusion part 42 can be prevented from moving when disturbed by external force, thereby ensuring the fixing effect of the extrusion part 42 on the flange edge 201.

[0056] In the second state, the pressing portion 42 of the block pressing mechanism 4 is located away from the first positioning structure 2 .

[0057] In some embodiments, Figure 6 As shown, the test bench also includes a clamp mechanism 5, which includes a second fixing portion 51 and a clamping portion 52 connected to each other. The second fixing portion 51 is fixed to the base 0, and the clamping portion 52 is used to clamp on the outer side of the nut seat 300 to fix the nut seat 300.

[0058] In this way, in the second state, after the nut seat 300 is fitted with the second positioning structure 3, the nut seat 300 can be clamped by the clamping portion 52 of the clamping mechanism 5 to fix the nut seat 300 on the second positioning structure 3, so that the position of the fixed plate 200 can be fixed by the clamping portion 52 to prevent the fixed plate 200 from shifting when being inspected under a low external force, thereby ensuring that the inspection of the fixed plate 200 can be carried out stably.

[0059] Alternatively, the clamping portion 52 may be a clamp.

[0060] In some embodiments, the clamping portion 52 can move toward or away from the nut seat 300 .

[0061] Thus, in the second state, before the nut seat 300 is fitted with the second positioning structure 3, the clamping portion 52 is moved to a position away from the second positioning structure 3 to prevent the clamping portion 52 from obstructing the fitting of the nut seat 300 of the fixing plate 200 with the second positioning structure 3; after the nut seat 300 is fitted with the second positioning structure 3, the clamping portion 52 is moved to a position close to the second positioning structure 3 to clamp and fix the nut seat 300 of the fixing plate 200. Thus, by moving the clamping portion 52 to a position close to or away from the second positioning structure 3, it is possible to ensure the fixing effect of the clamping portion 52 on the nut seat 300 while avoiding interference of the clamping portion 52 on the fitting of the nut seat 300 with the second positioning structure 3.

[0062] In the first state, the clamping portion 52 is located away from the second positioning structure 3 .

[0063] The clamp mechanism 5 further includes a second locking rod 53 and a second rotating arm 54, one end of the second rotating arm 54 is hinged to the second fixed portion 51, and the other end is connected to the clamping portion 52, so that the movement of the clamping portion 52 can be achieved by rotating the second rotating arm 54. The second locking rod 53 is hinged to the second fixed portion 51, and has a second locking state and a second loosening state. When the second locking rod 53 is in the second locking state, part of the second locking rod 53 abuts against the second rotating arm 54, so that the rotation of the second rotating arm 54 can be restricted. When the second locking rod 53 is in the second loosening state, the second locking rod 53 releases the second rotating arm 54, and the second rotating arm 54 can rotate freely. Therefore, when the clamping part 52 squeezes the nut seat 300, the second rotating arm 54 can be locked by the second locking rod 53, so as to prevent the clamping part 52 from moving when disturbed by external force, thereby ensuring the fixing effect of the clamping part 52 on the nut seat 300.

[0064] In some embodiments, in combination Figure 1 , Figure 2 As shown, the first area 11 has a plurality of first positioning holes 111 , and the plurality of first positioning holes 111 are used to be opposite to the second positioning holes 2011 on the flange edge 201 to position the flange edge 201 .

[0065] Among them, in the first state, when the fixed plate 200 is inspected, it is often necessary to fix the fixed plate 200 in a uniform position in order to unify the inspection reference of the fixed plate 200. Therefore, in the embodiment of the present disclosure, when the flange edge 201 is fit with the first positioning structure 2, the second positioning hole 2011 on the flange edge 201 can be fit with the first positioning hole 111 on the detection body 1, and the positioning pin can pass through the first positioning hole 111 and the second positioning hole 2011, so as to achieve the positioning of the fixed plate 200, so as to facilitate the inspection of the fixed plate 200.

[0066] In some embodiments, Figure 1 As shown, there is a gap between the edge of the flange edge 201 and the detection body 1. The detection platform also includes a stop pin 6, which is detachably fixed to the base 0. The first end 61 and the second end 62 of the stop pin 6 have different outer diameters. Whether the flatness of the flange edge 201 is qualified can be judged based on whether the first end 61 and the second end 62 can be inserted into the gap.

[0067] When the flange 201 is attached to the first positioning structure 2 and the nut seat 300 is attached to the second positioning structure 3, there is a gap between the edge of the flange 201 and the detection body 1. If the overall deformation of the flange 201 is within the required range, the distance between the edge of the flange 201 and the detection body 1 should be basically equal and can be controlled within a reasonable range. If the deformation of the flange 201 is large, the flange plate will be partially warped or concave, which will cause the distance between the warped or concave part of the flange 201 and the detection body 1 to be too small or too large.

[0068] In this way, when the end of the stop pin 6 with a smaller outer diameter cannot enter any part of the gap between the edge of the flange plate and the detection body 1, it means that the gap between a certain part of the edge of the flange 201 and the detection body 1 is too small, and the flatness of the flange 201 is poor, which does not meet the flatness requirements; when the end of the stop pin 6 with a larger outer diameter can enter any part of the gap between the edge of the flange plate and the detection body 1, it means that the gap between a certain part of the edge of the flange 201 and the detection body 1 is too large, and the flatness of the flange 201 is poor, which does not meet the flatness requirements. In this way, the stop pin 6 can be used to preliminarily judge whether the flatness of the flange 201 meets the standard, so as to reduce the inspection process of the fixed plate 200.

[0069] In addition, in the first state, the stop pin 6 can also detect the distance between the flat structure 82 and the raised portion 202 to preliminarily determine whether the flatness of the raised portion 202 meets the standard.

[0070] Exemplarily, the distance between the edge of the flange 201 and the detection body 1 should be controlled at about 5 mm, for example, it needs to be controlled in the range of [4.5 mm, 5.5 mm). In this case, the outer diameter of one end of the stop pin 6 can be set to 4.5 mm, and the outer diameter of the other end can be set to 5.5 mm.

[0071] The inspection platform includes a plurality of pass and stop pins 6 , and the specifications of the plurality of pass and stop pins 6 are different, so as to be used when the state of the inspection platform changes or the inspection standard of the fixing plate 200 changes.

[0072] In some embodiments, Figure 1 As shown, the testing platform further includes two handles 7 , which are respectively fixed on opposite sides of the base 0 .

[0073] In this way, the test bench can be carried more conveniently by means of the handle 7, thereby improving the portability of the test bench.

[0074] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present disclosure. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0075] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the present disclosure. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0076] In the description of the present disclosure, it is necessary to understand that the orientation or positional relationship indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present disclosure and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present disclosure; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0077] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0078] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present disclosure.

[0079] The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
