DETAILED DESCRIPTION

The present disclosure is described in further detail with reference to the accompanying drawings, to clearly present the objects, technical solutions, and advantages of the present disclosure.

In a detection process, it is necessary to support a flexible plate structure by a support device, and the flexible plate structure has a bending curvature.

In the related art, the support device is provided with a support surface for supporting the flexible plate structure, and the bending curvature of the support surface of each support device is constant. For detection of the performance of the flexible plate structure under different bending curvatures, a plurality of support devices corresponding to different bending curvatures are desired, which is costly. Moreover, converting the flexible plate structure between the plurality of support devices is cumbersome and time-consuming.

FIG.1is a schematic structural diagram of a support device according to an embodiment of the present disclosure. Referring toFIG.1, the support device includes: a base10, a support rod20, a plurality of contact rods30, and a regulation structure40. The support rod20is disposed on the base10. The plurality of contact rods30are parallel to the support rod20and arranged in an arc around the support rod20, wherein side faces of the plurality of contact rods30provide a support surface for supporting the flexible plate structure200. The regulation structure40is connected to the support rod20and the contact rod30, wherein the regulation structure40is configured to regulate a distance between the contact rod30and the support rod20to regulate a bending curvature of the support surface. The regulation structure40may regulate a minimum distance between the contact rod30and the support rod20, or regulate a distance between a central line of the contact rod30and a central line of the support rod20.

In the embodiments of the present disclosure, the plurality of contact rods30are parallel to the support rod20and arranged in an arc around the support rod20, wherein side faces of the plurality of contact rods30may form an approximately arc-shaped support surface for supporting the flexible plate structure200. A central line of the support rod20is a central line of the support surface, and a sum of a radius of the support rod20, a minimum distance between the contact rod30and the support rod20, and a diameter of the contact rod30is a radius of the support surface. The radius of the support surface is negatively correlated with the bending curvature of the support surface, that is, the greater the radius of the support surface, the smaller the bending curvature of the support surface, and the smaller the radius of the support surface, and the greater the bending curvature of the support surface. Thus, the bending curvature of the support surface may be regulated by regulating the minimum distance between the contact rod30and the support rod20by the regulation structure40. In the process of detecting the performance of the flexible plate structure200under different bending curvatures, the flexible plate structure200is attached to the support surface, and the bending curvature of the support surface is equal to the bending curvature of the flexible plate structure200. Therefore, in the process of detecting the performance of the flexible plate structure200under different bending curvatures, the support device may support the flexible plate structure200under different bending curvatures, and thus the cost is reduced. Further, in the detection process, it is not necessary to replace the support device, which improves the work efficiency.

In the embodiments of the present disclosure, in the case that the flexible plate structure200is attached to the support surface, the flexible plate structure200may be pasted on the contact rod30, such that the stability of the flexible plate structure200in the detecting process is ensured, and accuracy of the detection is prevented from being affected.

In the embodiments of the present disclosure, the central line of the contact rod30is parallel to the central line of the support rod20.

FIG.2is a schematic composite diagram of a support rod, a contact rod, and a regulation structure according to an embodiment of the present disclosure. Referring toFIGS.1and2, the regulation structure40includes two hinge rings401, a plurality of first connection rods402, and a plurality of second connection rods403. Two hinge rings401are spaced apart on the support rod20, wherein at least one of the two hinge rings401is configured to be movably disposed on the support rod20, and a moving direction of the hinge ring401is consistent with a length direction a of the support rod20. The plurality of first connection rods402are in one-to-one correspondence to the plurality of contact rods30, wherein one end of the first connection rod402is hinged to the corresponding contact rod30, and the other end of the first connection rod402is hinged to one of the two hinge rings401. The plurality of second connection rods403are in one-to-one correspondence to the plurality of contact rods30, wherein one end of the second connection rod403is hinged to the corresponding contact rod30, and the other end of the second connection rod403is hinged to the other of the two hinge rings401.

Because the first connection rod402is hinged to one of the two hinged rings401, the first connection rod402is hinged to the contact rod30, the contact rod30is hinged to the second connection rod403, the second connection rod403is hinged to the other of the two hinged rings401, and at least one of the two hinged rings401is movable along the length direction a of the support rod20. In the case that the bending curvature of the support surface needs to be regulated, the position of at least one of the two hinge rings401on the support rod20is regulated, such that a distance between the two hinge rings401changes, and the first connection rod402and the second connection rod403rotate around the hinge shaft, and thus an angle between the first connection rod402and the support rod20and an angle between the second connection rod403and the support rod20change. In this way, the distance between the contact rod30and the support rod20is changed, and thus the radius of the support surface is regulated. In the process of detecting the performance of the flexible plate structure200under different bending curvatures, it is convenient to regulate the bending curvature of the flexible plate structure200.

Exemplarily, in the embodiment shown inFIG.2, the two hinge rings401are both movably disposed on the support rod20. The regulation structure40further includes: two regulation rings404and a limit element405. The two regulation rings404are spaced apart on the support rod20, and threaded to the support rod20, wherein the two hinge rings401are disposed between the two regulation rings404. The limit element405is disposed on the support rod20, and the limit element405is configured to limit the position of the hinge ring401on the support rod20.

The regulation ring404is threaded to the support rod20, and a distance between the two regulation rings404may be regulated by rotating the regulation rings404. Because the hinge ring401is disposed between the two regulation rings404, in the case that the regulation ring404is in contact with the hinge ring401, the position of the hinge ring401on the support rod20is changed during the movement of the regulation ring404. At the same time, the limit element405is configured to limit the position of the hinge ring401on the support rod20, and the distance between the two hinge rings401is maintained constant upon regulation of the position of the hinge ring401, such that the distance between the contact rod30and the support rod20is maintained constant. In the process of detecting the performance of the flexible plate structure200under different bending curvatures, the radius of the support surface may not be changed, the bending curvature of the flexible plate structure200may not be affected, and detection results are prevented from being affected.

The first connection rod402and the second connection rod403are both hinged to the hinge rings401. The angle between the first connection rod402and the support rod20, and the angle between the second connection rod403and the support rod20are changed in the case that the distance between the two hinge rings401changes, such that the radius of the support surface is regulated. In the process of detecting the performance of the flexible plate structure200under different bending curvatures, it is more convenient to regulate the bending curvature of the flexible plate structure200by rotating the regulation ring404.

As illustrated inFIG.2, the support rod20is provided with an external thread, and the regulation ring404is provided with an internal thread, such that a thread connection is achieved between the regulation ring404and the support rod20.

The other of the two regulation rings404is fixed to the other end of the support rod20, and the distance between the two hinge rings401is regulated by one of the two regulation rings404.

For example, in the vertical direction, an upper end of the support rod20is provided with the external thread, and the thread connection is achieved by the regulation ring404with the internal thread and the upper end of the support rod20with the external thread. The other of the two regulation rings404is fixed to a lower end of the support rod20.

In some embodiments, the limit element405is a first elastic element, wherein two ends of the first elastic element are abutted against the two hinge rings401respectively, and the first elastic element is in a state of supplying a pressing force to the abutted two hinge rings401.

The first elastic element is disposed between the two hinge rings401, and the first elastic element generates a force towards the regulation ring404on the hinge ring401. Due to the thread connection between the regulation ring404and the support rod20, the regulation ring404limits a movement of the hinge ring401away from the first elastic element. The position of the hinge ring401is limited by the first elastic element and the regulation ring404.

In some embodiments, the first elastic element is a first compression spring in a compressed state. It is more convenient that the first compression spring supplies the pressing force to the hinge ring401. Meanwhile, the cost of producing the support device for the flexible plate structure is reduced because the compression spring is easy to obtain.

In some embodiments, the first elastic element also may be a first spring piece in a compressed state, wherein the first spring piece may supply the pressing force to the hinge ring401likewise.

In some embodiments, the distance between the two hinge rings401may be limited in other ways. Such as, the support rod20is provided with a plurality of through-holes, wherein extension directions of the plurality of through-holes are perpendicular to the length direction a of the support rod20.

Referring toFIG.9, the surface of the baffle501opposite to the baseplate102is provided with a strip-shaped groove511, wherein an extension direction of the strip-shaped groove511is parallel to the length direction of the contact rod30, and a contact rod30is disposed inside the strip-shaped groove511.

In the embodiments of the present disclosure, the strip-shaped groove511is disposed on the surface of the baffle501, and the contact rod30is disposed inside the strip-shaped groove511, which enhances a limit effect, and preventing the contact30from rotating.

As illustrated inFIG.9, the strip-shaped groove511is disposed proximal to a side of the baffle501, and when the whole support device is produced completely, the strip-shaped groove511is opposite to the contact rod30, such that the contact rod30is disposed inside the strip-shaped groove511, thereby enhancing the limit effect.

In some embodiments, a cross section of the strip-shaped groove511is semicircular, and a radius of the semicircle is equal to a radius of the contact rod30.

FIG.10is a top view ofFIG.2. Referring toFIGS.2and10, the plurality of contact rods30are equally spaced around the support rod20in a circular array.

In the embodiments of the present disclosure, the plurality of contact rods30are equally spaced around the support rod20in a circular array, ensuring gentleness of the formed support surface. Meanwhile, the support surface formed by the plurality of contact rods30is a cylindrical side face. In the process of regulating the bending curvature, as the contact rod30rotates, the flexible plate structure200may be attached to the support surface all the time, which is more convenient.

In some embodiments, the contact rod30may take the central line of the support rod20as the central line, and equally spaced apart in a fan array.

As illustrated inFIG.10, a graph enclosed by side faces of the plurality rods30is a polygon. As illustrated in a dotted line inFIG.10, the greater the number of contact rods30is, the more approximate the graph enclosed by the side faces of the contact rods30is to the circle.

FIG.11is a schematic diagram of a flexible plate structure attached to a support surface according to an embodiment of the present disclosure. Referring toFIG.11, the flexible plate structure200is attached to the support surface A, such that the flexible plate structure200is provided with an arc-shaped bending surface.

In the embodiments of the present disclosure, the number of contact rods30is from 15 to 30. By limiting the number of contact rods30, the support surface formed by the contact rods30is approximately arc-shaped, such that the bending of the flexible plate structure200on the support surface is approximately arc-shaped, and increasing the accuracy of the subsequent detection results.

Exemplarily, the number of contact rods30is 20.

The technical solutions according to the embodiments of the present disclosure achieve at least the following beneficial effects.

The plurality of contact rods30are parallel to the support rod20and arranged in an arc around the support rod20, and the side faces of the plurality of contact rods30form an approximately arc-shaped support surface to support the flexible plate structure200. The central line of the support rod20is the central line of the support surface, and the sum of the radius of the support rod20, a minimum distance between the contact rod30and the support rod20, and the diameter of the contact rod30is the radius of the support surface. The radius of the support surface is negatively correlated with the bending curvature of the support surface, that is, the greater the radius of the support surface, the smaller the bending curvature of the support surface, and the smaller the radius of the support surface, and the greater the bending curvature of the support surface. Thus, the bending curvature of the support surface may be regulated by regulating the minimum distance between the contact rod30and the support rod20by the regulation structure40. In the process of detecting the performance of the flexible plate structure200under different bending curvatures, the flexible plate structure200is attached to the support surface, and the bending curvature of the support surface is equal to the bending curvature of the flexible plate structure200. Therefore, in the detection process, a support device may support the flexible plate structure200under different bending curvatures, and thus the cost is reduced. Further, in the detection process, it is not necessary to replace the support device, which improve the work efficiency.

Described above are merely optional embodiments of the present disclosure, and are not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present disclosure shall fall within the protection scope of the present disclosure.
