In order to make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail with reference to the accompanying drawings.

To facilitate understanding of the supporting component provided in the embodiments of the present application, an application scenario of the supporting component is first described below, where the supporting component is applied to a mobile terminal, particularly a mobile terminal with a bendable screen, such as a mobile phone, a PDA, or a tablet computer. But it includes the structure as shown in fig. 1 regardless of which mobile terminal is adopted: the flexible screen comprises a first shell 20, a support assembly 10, a second shell 30 and a flexible screen 40. Referring to fig. 2a and 2b, the shaft 50 is rotatably connected to the first casing 20 and the second casing 30, respectively, and the shaft 50 may be a shaft commonly used in a conventional foldable mobile phone, and therefore, the structure thereof is not described herein again. The support assembly 10 is stacked on the rotating shaft 50, two ends of the support assembly 10 are respectively fixedly connected with the first casing 20 and the second casing 30, the first casing 20 and the second casing 30 are relatively rotated through bending deformation, and the flexible screen 40 covers the first casing 20, the second casing 30 and the support assembly 10 and is respectively bonded with the first casing 20, the second casing 30 and the support assembly 10, so as to form the structure shown in fig. 1. In use, the mobile terminal comprises two states, one is an unfolded state and the other is a folded state. Referring first to fig. 1, fig. 1 illustrates a unfolded state of the mobile terminal, in which the support assembly 10 is unfolded (not bent), and the first and

second housings

20 and 30 are arranged at both sides of the support assembly 10 in a flat unfolded state, in which the flexible screen 40 is flat. When bending is performed, as an arrow shown in fig. 1 shows a bending direction of the mobile terminal, during the bending, the first housing 20 and the second housing 30 rotate relatively, and the support assembly 10 deforms to bend, and after being folded, a state shown in fig. 3 is formed (only the state of the first housing 20, the second housing 30, and the support assembly 10 is shown, and the flexible screen is not shown), at this time, the first housing 20 and the second housing 30 are stacked relatively, and the flexible screen bends along with the first housing 20 and the second housing 30, and the support assembly 10 deforms. However, the support assembly 10 according to the embodiment of the present application is provided to easily disconnect the flexible screen 40 after being bent for a plurality of times, and the structure thereof will be described in detail with reference to the accompanying drawings.

As shown in fig. 4 and 5, fig. 4 is an exploded schematic view of the support assembly 10 provided in the embodiment of the present application, and fig. 5 is a schematic structural view of the support assembly 10. The support assembly 10 includes three components, a support layer 13, a first connecting layer 12, and a second connecting layer 11. When the supporting layer 13, the first connecting layer 12 and the second connecting layer 11 are fixed together, the supporting layer 13, the first connecting layer 12 and the second connecting layer 11 are connected in a stacked manner, and the supporting layer 13 and the second connecting layer 11 are arranged on both sides of the first connecting layer 12. The state of the layers of the support assembly 10 in use will be described with reference to the mobile terminal shown in fig. 1, and the second connection layer 11, the first connection layer 12 and the support layer 13 are arranged in series in a direction away from the flexible screen 40 when stacked. The layers of the support assembly 10 are described one by one below.

With continued reference to fig. 4, the supporting layer 13 shown in fig. 4 is a skeleton structure of the whole supporting assembly 10, and the supporting layer 13 includes a plurality of supporting members 131 arranged in a single row, and the plurality of supporting members 131 arranged in a single row are arranged at intervals. Referring to fig. 4 and 7 together, in the specific arrangement, the arrangement direction of the support 131 is perpendicular to two opposite side surfaces of the first casing 20 and the second casing 30 when they are unfolded, and the length direction of the support 131 is parallel to two opposite side surfaces of the first casing 20 and the second casing 30. As shown in fig. 6, when the mobile terminal is folded, the arrangement direction of the supporters 131 is changed from a linear arrangement of a single row to an arc arrangement of a single row. The first connection layer 12 is supported by the support 131 as a skeleton when the mobile terminal is folded and unfolded, and serves as a support of the flexible screen 40 when it is unfolded. In particular, the supporting member 131 may be made of a material having a certain supporting strength, such as a material having a certain rigidity, such as metal, plastic, etc., and in the structure shown in fig. 4, the supporting member 131 is made of a metal material, such as aluminum, iron, steel, etc. The shape of the supporting member 131 may be different, as shown in fig. 4, the supporting member 131 is a trapezoidal cylinder, and when the supporting member is specifically arranged, two bottoms of the trapezoidal cylinder are two surfaces parallel to the flexible screen, and two inclined surfaces of the trapezoidal cylinder are symmetrically arranged. When the supporting members 131 are arranged, the bottom of the trapezoidal cylinder with a larger width is located at the outer side of the folded mobile terminal, that is, when the mobile terminal is folded, two side surfaces of the trapezoidal cylinder are relatively close to each other as shown in fig. 6, and when the mobile terminal is unfolded, two inclined surfaces of the trapezoidal cylinder are far away from each other as shown in fig. 7. When the structure is adopted, the supporting pieces 131 can be arranged better and tightly, a larger supporting surface is provided, the bending radius of the supporting assembly 10 during bending can be limited through the inclined surfaces of the supporting pieces 131, and the occurrence of dead-folding state is avoided. Of course, the trapezoidal pillar shown in fig. 4 is only a specific embodiment, the shape of the supporting member 131 provided in the embodiment of the present application is not limited to the shape shown in fig. 4, and may also be different shapes such as a rectangular parallelepiped, a cylinder, or an elliptical cylinder, and the supporting member 131 only capable of supporting the supporting assembly 10 as a skeleton may be applied to the supporting assembly 10 provided in the embodiment of the present application.

With continued reference to fig. 4, the first connection layer 12 provided in the embodiment of the present application is used to connect a plurality of support members 131 arranged in a single row, and includes a flexible layer for connecting any adjacent support members 131, through which the support members 131 can be connected into a whole, and after being fixedly connected to the first casing 20 and the second casing 30, the first casing 20 and the second casing 30 can be rotated relative to each other by bending the flexible layer. As shown in fig. 4, the first connection layer 12 is a rectangular parallelepiped after being unfolded, and referring to fig. 5, fig. 5 is a structural diagram of the support assembly, and as can be seen from fig. 5, the support members 131 are arranged in a row at intervals, and then a plurality of support members 131 arranged in a single row are fixed together by the first connection layer 12. The supporting member 131 and the first connecting layer 12 are pressed together by using a mold during specific preparation, the supporting member 131 is placed in the lower mold and arranged during specific pressing, the first connecting layer 12 is fixed in the upper mold, and the upper mold and the lower mold are closed and pressed together to press the supporting member 131 and the first connecting layer 12 together. Of course, the above description only shows a specific connection manner between the first connecting layer 12 and the supporting member 131, and other manners may also be used to connect the supporting member 131 with the first connecting layer 12, for example, several slots are provided in the first connecting member 111, and the supporting member 131 is fixed by being clamped in the slots, so that the connection between the two may also be implemented, or a plurality of through holes are provided in the first connecting member 111, and the supporting member 131 penetrates through the through holes to be a framework of the whole supporting assembly 10. In addition, the material of the first connection layer 12 may be different, such as silicone or resin, which have certain flexibility. The first connection layer 12 is also a connection member connected to the two housings in the support assembly 10, and when the support assembly 10 is connected to the first housing 20 and the second housing 30, as shown in fig. 1, two ends of the first connection layer 12 are respectively fixedly connected to the first housing 20 and the second housing 30, specifically, the connection may be performed by a threaded connection member, and of course, other known methods may also be used for connection.

With continued reference to fig. 4, the support assembly 10 provided in the embodiment of the present application further includes a second connection layer 11, where the second connection layer 11 is a component used for being connected to the flexible layer in the support assembly 10, when particularly connected to the flexible screen 40, a side of the second connection layer 11 facing away from the first connection layer 12 is a connection surface used for being bonded to the flexible screen, and is bonded to the flexible screen 40 through the connection surface to fix the flexible screen 40, and in order to ensure a connection effect with the flexible screen 40, the adhesion performance of the second connection layer 11 provided in the embodiment of the present application is higher than that of the first connection layer 12. When the first connection layer 12 is made of silicone, the second connection layer 11 may be made of a polymer material layer, and the adhesive property of the polymer material layer is higher than that of silicone. When specifically setting up, this macromolecular material layer can specifically be the rete, dustproof screen cloth or common material layer that has good adhesive property such as non-woven fabrics.

As shown in fig. 6, mainly the flexible layer between the two supports 131 is deformed when the flexible screen is bent. Therefore, when the second connection layer 11 is disposed, in order to avoid deformation of the disposed second connection layer 11 and the first connection layer 12, the second connection layer 11 is specifically disposed and includes a plurality of connection members 111, as shown in fig. 4, the connection members 111 are rectangular, and the length direction is the same as the length direction of the support members 131, and the connection members 111 are also arranged in a single row, and the arrangement is the same as the arrangement of the support members 131, which is specifically referred to the description of the arrangement of the support members 131, and is not repeated herein. In addition, when the connecting member 111 is disposed, there is a certain corresponding relationship between the connecting member 111 and the supporting member 131, specifically: the plurality of connecting members 111 are arranged on both sides of the first connecting layer 12 in a one-to-one correspondence with at least some of the supporting members 131 in the plurality of supporting members 131 arranged in a single row, that is, each connecting member 111 is arranged on both sides of the first connecting layer 12 in a correspondence with one supporting member 131. Specifically, there may be various cases, such as a case where each of the plurality of support members 131 arranged in a single row corresponds to one of the connection members 111, or a case where each of the support members 131 corresponds to one of the connection members 111 in a part of the plurality of support members 131 arranged in a single row. For example, taking 5 supporting members 131 as an example, 5 supporting members 131 corresponding to 5 connecting members 111 may be adopted, or 3 supporting members 131 of the 5 supporting members 131 corresponding to the connecting members 111 may be adopted; however, in any case, only one supporting member 131 is required for each connecting member 111. When the mode is adopted, the connecting piece 111 can be supported through the strength of the supporting piece 131, and when the flexible screen 40 is in press fit bonding with the connecting piece 111, the supporting piece 131 can provide supporting force to ensure the firmness in bonding.

The connection of the second connection layer 11 to other layers may be different, and may be either the first connection layer 12 or the support layer 13, which will be described below with reference to the drawings. Referring first to fig. 4, in the structure shown in fig. 4, the second connection layer 11 is connected to the first connection layer 12, and the polymer material layer is used as an example for description, and the polymer material layer is fixedly connected to the first connection layer 12 by molding. Reference is also made to the description of the fixing of the first connection layer 12 and the support layer 13. In the fixing of the support layer 13 in the lower mold, the silica gel layer and the plurality of support members 131 arranged in a single row are first pressed and fixed together by a mold forming process, and then the polymer material layer and the silica gel layer are pressed and fixed. When the high polymer material layer is connected with the silica gel layer, in order to enable the silica gel layer to be firmly fixed with the high polymer material layer, a primer layer is coated on the silica gel layer before lamination, and then mould forming is carried out, wherein the primer layer can change the high polymer material layer so as to firmly connect the silica gel layer with the high polymer material layer. Of course, after the primer layer is coated, the adhesive layer is coated on the primer layer, so that the connection strength between the silica gel layer and the high polymer material layer can be improved.

Referring to fig. 8 and 9, fig. 8 and 9 show one way of fixedly connecting the second connection layer 11 to the support layer 13. Referring first to fig. 9, fig. 9 is an exploded view of the support assembly 10, when the support members 131 are connected to the second connection layer 11, at least a portion of the support members 131 in the support layer 13 correspond to the connection members 111 one by one, and the plurality of connection members 111 in the second connection layer 11 are adhered to a portion of the support members 131 in the plurality of support members 131 arranged in a single row, which is exposed outside the first connection layer 12. In fig. 9, a plurality of supporting members 131 arranged in a single row are shown to correspond to the connecting members 111 one by one, but it should be understood that fig. 9 is merely an example, and in the supporting assembly 10 provided in the embodiment of the present application, a part of the supporting members 131 may correspond to the connecting members 111. The structure of the supporting member 131 not corresponding to the connecting member 111 is similar to that of the supporting member 131 described above, and thus, the description thereof is omitted. Focusing on the structure of the supporting member 131 corresponding to the connecting member 111, the supporting member 131 corresponding to the connecting member 111 penetrates through the first connecting layer 12 and is partially exposed, when the structure is specifically set, the cross section of the supporting member 131 is in a convex shape, and the state of the supporting assembly 10 connected to the mobile terminal is taken as a reference state, one surface of the supporting member 131 facing the flexible screen 40 is provided with a protrusion 1311, the first connecting layer 12 is provided with a plurality of through grooves, the plurality of through grooves correspond to the plurality of protrusions 1311 one by one, and when the first connecting layer 12 and the supporting member 131 are pressed and fixed, each protrusion 1311 is correspondingly inserted into the corresponding through groove and exposed. When the connection members 111 are pressed, the plurality of connection members 111 are adhered to the protrusions 1311 in a one-to-one correspondence, and are specifically adhered to the surfaces of the corresponding protrusions 1311 facing the flexible screen 40.

With continued reference to fig. 8 and 9, the protrusion 1311, when inserted into the channel, may be exposed outside of the channel or may be located within the channel. As shown in fig. 9, the side of the protrusion 1311 facing the flexible screen 40 is flush with the side of the first connection layer 12 facing the flexible screen 40, and at this time, the connection member 111 is exposed outside the through-groove when the connection member 111 is bonded to the protrusion 1311. Of course, the protrusion 1311 may not be exposed outside the surface of the first connection layer 12 facing the flexible screen 40, the surface of the protrusion 1311 facing the second connection layer 11 is located in the through groove, when the connection member 111 is connected to the protrusion 1311, the connection position of the protrusion 1311 and the connection member 111 is located in the through groove, and at this time, the connection member 111 and the first connection layer 12 may be approximately flush. In actual production, the above two modes can be applied to the embodiment of the present application.

It should be understood that, although fig. 8 and 9 illustrate that a plurality of the supporting members 131 arranged in a single row correspond to the connecting members 111, in the supporting assembly 10 provided in the embodiment of the present application, a part of the supporting members 131 correspond to the connecting members 111, and when a part of the supporting members 131 correspond to the connecting members 111, the structure of the supporting members 131 corresponding to the connecting members 111 can be referred to the above description.

Of course, in addition to the second connection layer 11, the second connection layer 11 provided in the embodiments of the present application may also be formed in other manners, such as the second connection layer 11 and the support layer 13 are formed as a single body. At this time, at least a portion of the supporting members 131 of the plurality of supporting members 131 arranged in a single row pass through the first connection layer 12 and are partially exposed; the second connection layer 11 is a portion where a plurality of supporters 131 arranged in a single row are exposed outside the first connection layer 12. In a specific implementation, the first connection layer 12 is provided with a plurality of through grooves; at least a part of the supporters 131 among the plurality of supporters 131 arranged in a single row is provided with protrusions; at least part of the protrusions of the supporting members 131 are inserted into the plurality of through grooves in a one-to-one correspondence and are partially exposed outside the first connection layer 12. With reference to the state when the support assembly 10 is connected to the flexible panel 40, the side of the protrusion facing the flexible panel 40 is exposed outside the side of the first connection layer 12 facing the flexible panel 40, and the portion of the protrusion exposed outside the first connection layer 12 may serve as the second connection layer 11 and be bonded to the flexible panel 40. In this structure, the adhesive effect of the supporting member 131 in the supporting layer 13 should be greater than that of the silicone layer, so that the supporting member 10 and the flexible screen 40 can be firmly adhered together by using the adhesive. When the supporting member 131 is specifically formed, different materials such as stainless steel, aluminum alloy, and plastic may be used.

The embodiment of the application provides a mobile terminal in addition to the above-mentioned supporting component, and the mobile terminal may be a mobile terminal such as a foldable mobile phone and a tablet computer, but whichever type is adopted, the mobile terminal includes: the flexible screen comprises a first shell 20, a support assembly 10, a second shell 30 and a flexible screen 40. Referring to fig. 2a and 2b, when the first casing 20 and the second casing 30 are rotatably connected, the first casing 20 and the second casing 30 are respectively rotatably connected through a rotating shaft 50, and the rotating shaft 50 is a commonly used rotating shaft in a conventional foldable mobile phone, so the structure thereof is not repeated herein. The support assembly 10 is stacked on the rotating shaft 50, two ends of the support assembly 10 are respectively fixedly connected with the first casing 20 and the second casing 30, the first casing 20 and the second casing 30 are relatively rotated through bending deformation, and the flexible screen 40 covers the first casing 20, the second casing 30 and the support assembly 10 and is respectively bonded with the first casing 20, the second casing 30 and the support assembly 10, so as to form the structure shown in fig. 1. In use, the mobile terminal comprises two states, one is an unfolded state and the other is a folded state. Referring first to fig. 1, fig. 1 illustrates a unfolded state of the mobile terminal, in which the support assembly 10 is unfolded (not bent), and the first and

second housings

20 and 30 are arranged at both sides of the support assembly 10 in a flat unfolded state, in which the flexible screen 40 is flat. When bending is performed, as an arrow shown in fig. 1 shows a bending direction of the mobile terminal, during the bending, the first housing 20 and the second housing 30 rotate relatively, and the support assembly 10 deforms to bend, and after being folded, a state shown in fig. 3 is formed (only the state of the first housing 20, the second housing 30, and the support assembly 10 is shown, and the flexible screen is not shown), at this time, the first housing 20 and the second housing 30 are stacked relatively, and the flexible screen bends along with the first housing 20 and the second housing 30, and the support assembly 10 deforms. The support assembly 10 is connected with the flexible screen 40 through the second connecting layer 11, and the bonding performance of the second connecting layer 11 is higher than that of the first connecting layer 12, so that when the flexible screen 40 is bonded, the second connecting layer 11 and the bonding glue have a good bonding effect, the effect that the flexible screen 40 is disconnected from the support assembly 10 after being bent for multiple times is improved, and the using effect of the mobile terminal is improved.
