[0016] In some embodiments, the cross-sectional shape of the blocking strip and the first groove includes one or more of a trapezoidal, circular, elliptical, convex, and semicircular shape; wherein the blocking strip includes a hollow structure and a solid structure;

[0017] The cross-sectional shape of the blocking strip is the same as or different from that of the first groove.

[0018] In some embodiments, after the sealing strip is attracted by the attraction portion, the cross-sectional length of the portion in contact with the bottom is greater than or equal to one tenth of the cross-sectional length of the bottom and less than or equal to one third of the cross-sectional length of the bottom.

[0039] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0040] In order to solve the aforementioned problems, an embodiment of the present application provides a folding structure 10 . Figure 1What is shown is a schematic structural diagram of the folding structure 10. Figure 1 As shown, the folding structure 10 includes a main shaft 11 , two rotating parts 12 and two supporting parts 13 .

[0041] The main shaft 11 includes a bottom 111 and two side walls 112. The two side walls 112 are located on opposite sides of the bottom 111 and are connected to the bottom 111. The two side walls 112 extend upwards toward the same side of the bottom 111. Figure 1 The flat part at the bottom of the main shaft 11. The two side walls 112 on both sides of the bottom 111 are Figure 1 The bottom portion 111 has raised extensions on both sides, and the raised extensions are located on the same side of the bottom portion 111 .

[0042] It should be noted that although Figure 1 In the embodiment shown, the cross-sectional shape of the main shaft 11 can be formed into a U-shaped structure by the bottom 111 and the two side walls 112, but it is not limited thereto. The cross-sectional shape of the main shaft 11 can also be other shapes that meet the above requirements.

[0043] The two rotating members 12 are rotatably connected to the two sidewalls 112, respectively. The two supporting members 13 are respectively connected to the two rotating members 12, allowing the supporting members 13 to rotate with the corresponding rotating members 12. Both supporting members 13 have at least one first groove 131 defined on the side facing the main shaft 11. A magnetic sealing strip 14 is disposed within the first groove 131, capable of moving within the first groove 131.

[0044] Among them, the two rotating parts 12 are rotatably connected to the two side walls 112 respectively. The top ends of the two side walls 112 away from the bottom 111 are provided with rotating shafts, and the rotating parts 12 are respectively connected to the rotating shafts, but are not limited to this. The rotating parts 12 can also be rotatably connected to the two side walls 112 respectively in other ways.

[0045] Furthermore, at least one first groove 131 is provided on each side of the two support members 13 facing the main shaft member 11, that is, Figure 1 As shown, each of the two support members 13 may have one first groove 131, or each of the two support members 13 may have two first grooves 131, or each of the two support members 13 may have three first grooves 131, but the present invention is not limited thereto. The number of first grooves 131 may be flexibly set according to the process capability and actual product requirements.

[0046] At the same time, the two supporting members 13 are connected to the two rotating members 12 respectively, and can be Figure 1As shown, the first connecting portion 121 extending from the rotating member 12 and the second connecting portion 132 extending from the supporting member 13 are connected to each other, so that the two supporting members 13 are connected to the two rotating members 12 respectively. That is, the connection between the first connecting portion 121 and the second connecting portion 132 is used to connect the supporting member 13 to the corresponding rotating member 12. It should be noted that Figure 1 The embodiment shown in which the connection function is achieved by extending the first connection part 121 and the second connection part 132 is only a more feasible embodiment, but is not limited to this in other embodiments. The first connection part 121 and the second connection part 132 can also be connected to each other in other more feasible ways.

[0047] The main shaft 11 is provided with an attraction portion 113 on one side thereof facing the support 13 . The attraction portion 113 is used to attract the magnetic blocking strip 14 . The main shaft 11 is provided with at least two attraction portions 113 corresponding to the two first grooves 131 .

[0048] refer to Figure 1 The folding structure 10 shown has many movable parts due to its movable characteristics. Figure 1 The rotating member 12 and the supporting member 13 can both rotate relative to the main shaft member 11. Since the folding structure 10 needs to be movable, it is inevitable that there needs to be a certain gap between the parts that are close and have relative displacement, such as Figure 1 The gaps between the support member 13 and the main shaft member 11 are shown to prevent wear caused by long-term friction and the influence of friction on the relative displacement between the components. Dirt such as gravel in the environment can enter the folding structure 10 through these gaps, causing damage to the folding structure 10 and affecting the normal operation and service life of the folding structure 10.

[0049] By providing the suction portion 113 corresponding to the first groove 131, it is ensured that at least when the support member 13 is in a specific position relative to the main shaft member 11, the suction portion 113 attracts the blocking strip 14 located in the first groove 131 and brings it into contact with the suction portion 113. The blocking strip 14 attracted and contacted by the suction portion 113 seals the gap between the main shaft member 11 and the support member 13, thereby preventing environmental contaminants, including sand and gravel, from entering the folding structure 10 through the gap. Furthermore, this prevents environmental contaminants, including sand and gravel, from affecting the normal operation and service life of the folding structure 10.

[0050] In some embodiments, Figure 2 and Figure 3 The schematic diagrams of the folding structure 10 shown are respectively in a specific state. Figure 2 and Figure 3As shown, both support members 13 have a first position and a second position relative to the main shaft member 11. When the support member 13 is in the first position, the support member 13 is opposite to the bottom 111, and when the support member 13 is in the second position, the support member 13 is opposite to the side wall 112. Figure 2 1 is a schematic diagram showing that the support member 13 is located at the first position and is opposite to the bottom 111 . Figure 3 It is shown that when the support member 13 is located at the second position, the support member 13 is opposite to the side wall 112 .

[0051] The bottom 111 is provided with an attraction portion 113 corresponding to the first groove 131 on the support member 13 at the first position. The side walls 112 are provided with attraction portions 113 corresponding to the first groove 131 on the support member 13 at the second position.

[0052] When the support member 13 is in the first position, the support member 13 and the main shaft member 11 are in a relatively stable state, and the folding structure 10 can be considered to be in an open state. When the support member 13 is in the second position, the support member 13 and the main shaft member 11 are in another relatively stable state, and the folding structure 10 can be considered to be in a closed state. Therefore, when the support member 13 is in the first position or the second position, the support member 13 and the main shaft member 11 are in a relatively stable state. Since the folding structure 10 is in operation, it is in the open state or the closed state for most of its working time.

[0053] Since the folding structure 10 is in an open or closed state for most of its operating time, that is, the support member 13 is in the first position or the second position for most of its operating time, the bottom 111 is provided with a suction portion 113 corresponding to the first groove 131 on the support member 13 in the first position, and the side walls 112 are provided with suction portions 113 corresponding to the first groove 131 on the support member 13 in the second position. This allows the folding structure 10 to seal the gap by attracting the blocking strip 14 through the suction portion 113 during most of its operating time. Furthermore, since the suction portion 113 is only provided when the support member 13 is in the first or second position, the number of blocking strips 14 can be reduced, thereby reducing the cost of achieving the gap-sealing effect of the blocking strip 14.

[0054] Therefore, such a setting can reduce the cost of achieving the effect while achieving the folding structure 10 to seal the gap by attracting the sealing strip 14 through the suction part 113 during most of the working time, thereby achieving the effect of sealing the gap with better sealing strip 14 at a lower cost.

[0055] In some embodiments, as Figure 1 、 Figure 2 and Figure 3As shown, the attracting portion 113 includes a first attracting portion 1131 and a second attracting portion 1132. The first attracting portion 1131 is disposed corresponding to the first groove 131 at the first position, and the second attracting portion 1132 is disposed corresponding to the first groove 131 at the second position.

[0056] At least one suction portion 113 is further provided between each first suction portion 1131 and the adjacent second suction portion 1132. Figure 3 The content shown, Figure 3 The first attraction portion 1131 located in the region Q1 and the second attraction portion 1132 located in the region Q2 are adjacent first attraction portions 1131 and second attraction portions 1132 .

[0057] At least one of the above-mentioned suction parts 113 is further provided between each first suction part 1131 and the adjacent second suction part 1132. Figure 3 As shown, at least one suction portion 113 is provided between each first suction portion 1131 and an adjacent second suction portion 1132 on the surface of the main shaft 11 facing the support 13 . Figure 3 The suction portion 113 located in the region Q3 is shown in FIG. 1 . The suction portion 113 located in the region Q3 is the suction portion 113 located between the adjacent first suction portion 1131 and the second suction portion 1132 .

[0058] One suction portion 113 may be provided between each first suction portion 1131 and the adjacent second suction portion 1132, or two suction portions 113 may be provided between each first suction portion 1131 and the adjacent second suction portion 1132, or three suction portions 113 may be provided between each first suction portion 1131 and the adjacent second suction portion 1132, but the present invention is not limited thereto.

[0059] In this way, by providing at least one suction portion 113 between each first suction portion 1131 and the adjacent second suction portion 1132, the blocking strip 14 can be attracted by at least one suction portion 113 located between each first suction portion 1131 and the adjacent second suction portion 1132 during the process of the support member 13 rotating from the first position to the second position, or during the process of the support member 13 rotating from the second position to the first position. Thus, it can be ensured that the blocking strip 14 blocks the gap between the support member 13 and the main shaft member 11 during the rotation of the support member 13, and further prevents dirt in the environment including gravel from affecting the normal operation and service life of the folding structure 10.

[0060] In some embodiments, Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8The figure shows a partial enlarged view of the cross section of the support member 13 located at the first groove 131. Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, and reference Figure 1 In the schematic diagram of the overall folding structure 10 shown, the first groove 131 extends from the surface of the support member 13 facing the main shaft member 11 and extends into the support member 13. The cross-section of the portion of the first groove 131 extending into the support member 13 parallel to the surface B1 of the support member 13 is the first cross-section. The area of ​​the opening of the first groove 131 on the surface of the support member 13 is smaller than the maximum area of ​​the first cross-section.

[0061] Specifically, the portion of the first groove 131 extending into the support member 13 parallel to the surface B1 of the support member 13 has a first cross-section, that is, the first groove 131 may include multiple first cross-sections. The area of ​​the opening of the first groove 131 on the surface B1 of the support member 13 is smaller than the maximum cross-sectional area of ​​the first cross-section.

[0062] The section of the blocking strip 14 located within the first groove 131 parallel to the surface of the support member 13 is the second cross-section. The area of ​​the blocking strip 14 at the opening is smaller than the maximum area of ​​the second cross-section. Similarly, referring to the above, the section of the blocking strip 14 located within the first groove 131 parallel to the surface B1 of the support member 13 is the second cross-section, meaning that the blocking strip 14 may include multiple second cross-sections. The area of ​​the blocking strip 14 located at the opening on the surface B1 of the support member 13 is smaller than the maximum cross-sectional area of ​​the second cross-section.

[0063] Through the above-mentioned arrangement, it is possible to specifically realize that the blocking strip 14 is movably positioned in the first groove 131, and the gap between the main shaft 11 and the support member 13 is blocked by the blocking strip 14 attracted and contacted by the attraction portion 113, thereby specifically preventing dirt in the environment including gravel from entering the folding structure 10 through these gaps, and further, specifically preventing dirt in the environment including gravel from affecting the normal operation and service life of the folding structure 10.

[0064] In some embodiments, Figure 9 and Figure 10 The figure also shows a partial enlarged view of the cross section of the support member 13 located at the first groove 131. Figure 9 and Figure 10As shown, the first groove 131 extends from the surface B1 of the support member 13 facing the spindle member 11 and extends into the support member 13. The cross-section of the portion of the first groove 131 extending into the support member 13 parallel to the surface B1 of the support member 13 is a first cross-section. The area of ​​the opening of the first groove 131 on the surface of the support member 13 is smaller than the maximum area of ​​the first cross-section.

[0065] Specifically, the portion of the first groove 131 extending into the support member 13 parallel to the surface B1 of the support member 13 has a first cross-section, that is, the first groove 131 may include multiple first cross-sections. The area of ​​the opening of the first groove 131 on the surface of the support member 13 is smaller than the maximum cross-sectional area of ​​the first cross-section.

[0066] The blocking strip 14 comprises a sheet-like structure and can be deformed along a direction extending out of the first groove under the action of the suction portion 113 .

[0067] Through the above-mentioned arrangement, it is also possible to specifically realize that the blocking strip 14 is movably located in the first groove 131, and the gap between the main shaft 11 and the support member 13 is blocked by the blocking strip 14 attracted and contacted by the attraction portion 113, thereby specifically preventing dirt in the environment including gravel from entering the folding structure 10 through these gaps, and further, specifically preventing dirt in the environment including gravel from affecting the normal operation and service life of the folding structure 10.

[0068] In some embodiments, as Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the cross-sectional shape of the blocking strip 14 and the first groove 131 includes one or more of a trapezoidal, circular, elliptical, convex, and semicircular shape.

[0069] The cross-sectional shape of the blocking strip 14 and the first groove 131 may be the same or different.

[0070] Specifically, such as Figure 4 As shown, the cross-sections of the blocking strip 14 and the first groove 131 can both be isosceles trapezoids. The base angles of the isosceles trapezoids can both be 60 degrees, i.e. Figure 4 The angles a and b shown in FIG can both be 60 degrees. The gap between the blocking strip 14 and the first groove 131 can be 0.1 mm, that is, Figure 4 The length of the gap L1 shown in FIG can be 0.1 mm, but is not limited thereto. The cross section of the blocking strip 14 and the first groove 131 can also be as follows: Figure 5Alternatively, the cross section of the blocking strip 14 and the first groove 131 may also be as shown. Figure 6 The figures are all circular, or they can be Figure 7 As shown, the cross section of the blocking strip 14 is circular, and the cross section of the first groove 131 is convex.

[0071] Furthermore, the cross-sectional shapes of the blocking strip 14 and the first groove 131 include trapezoidal, circular, elliptical, convex and semicircular shapes, that is, the cross-sectional shapes of the blocking strip 14 and the first groove 131 can be a combination of at least two shapes. Figure 8 As shown, Figure 8 The cross section of the blocking strip 14 shown is a combination of a semicircle and a rectangle.

[0072] It should be noted that the cross-sections of the blocking strip 14 and the first groove 131 can both be isosceles trapezoids, and the base angles of the isosceles trapezoids can both be 60 degrees. The gap between the blocking strip 14 and the first groove 131 can be 0.1 mm. This is only a more feasible embodiment, but is not limited to this in other embodiments. The base angle of the isosceles trapezoid can also be other angles within the range of greater than 0 degrees and less than 90 degrees. For example, the base angle of the isosceles trapezoid can also be 30 degrees, or the base angle of the isosceles trapezoid can also be 45 degrees, or the base angle of the isosceles trapezoid can also be 60 degrees. The size of the gap between the blocking strip 14 and the first groove 131 can also be set according to actual conditions. For example, the length of the gap between the blocking strip 14 and the first groove 131 can also be 0.05 mm, or the length of the gap between the blocking strip 14 and the first groove 131 can also be 0.15 mm, or the length of the gap between the blocking strip 14 and the first groove 131 can also be 0.2 mm.

[0073] In some embodiments, reference Figure 3 and Figure 4 As shown in the figure, after the sealing strip 14 is attracted by the suction portion 113, the cross-sectional length of the portion in contact with the bottom 111 is greater than or equal to one tenth of the cross-sectional length of the bottom 111 and less than or equal to one third of the cross-sectional length of the bottom 111. Figure 3 The length L2 shown in FIG. After the blocking strip 14 is attracted by the suction portion 113, the length of the cross section of the portion in contact with the bottom 111 is Figure 4 The length L3 is shown in FIG.

[0074] Specifically, after the sealing strip 14 is attracted by the suction portion 113, the cross-sectional length of the portion in contact with the bottom portion 111 is greater than or equal to one-tenth of the cross-sectional length of the bottom portion 111 and less than or equal to one-third of the cross-sectional length of the bottom portion 111. That is, the length L3 is greater than or equal to one-tenth of the length L2 and less than one-third of the length L2. Furthermore, the length L3 is greater than or equal to one-tenth of the length L2 and less than one-third of the length L2. The length L3 can be one-third of the length L2, one-fifth of the length L2, one-seventh of the length L2, one-ninth of the length L2, or one-tenth of the length L2, but is not limited thereto.

[0075] It should be noted that the Figure 4 The blocking strip 14 shown in the figure shows the length of the cross section of the portion of the blocking strip 14 in contact with the bottom 111 after being attracted by the attraction portion 113. This is only because it can most clearly show the length L3. In other figures, the length L3 of the partial enlarged view of the first groove 131 can also be referred to. Figure 4 The content shown.

[0076] When length L3 is less than one-tenth of length L2, not only does the narrow width of blocking strip 14 increase the difficulty of manufacturing blocking strip 14, but its thinness also makes it difficult to effectively prevent sand and gravel from entering folding structure 10. When length L3 is greater than one-third of length L2, blocking strip 14 is longer, resulting in a larger suction portion 113. The interaction force between the larger suction portions 113 can significantly affect the structure of main shaft 11.

[0077] Therefore, making the length L3 greater than or equal to one tenth of the length L2 and less than one third of the length L2 can enable the sealing strip 14 to better block environmental pollutants such as sand and gravel while effectively avoiding a major impact on the structure of the main shaft 11.

[0078] In some embodiments, Figure 11 What is shown is a top view of a support member 13. Figure 1 and Figure 11 As shown, the first groove 131 extends along the extension direction of the main shaft 11. In the extension direction of the first groove 131, the distance between the first groove 131 and the edge of the support member 13 is greater than or equal to 1 mm and less than or equal to 10 mm.

[0079] in, Figure 1 and Figure 11The figure shows the extension direction of the main shaft 11, that is, the first direction X. The first groove 131 extends along the first direction X. Moreover, in the first direction X, the distance between the first groove 131 and the edge of the support member 13 is greater than or equal to 1 mm and less than or equal to 10 mm. Figure 11 The length L4 and the length L5 shown in FIG are both greater than or equal to 1 mm and less than or equal to 10 mm.

[0080] Moreover, both the length L4 and the length L5 are greater than or equal to 1 mm and less than or equal to 10 mm. The length L4 and the length L5 can be both 1 mm, or both can be 5 mm, or both can be 10 mm, or the length L4 can be 1 mm and the length L5 can be 5 mm, or the length L4 can be 5 mm and the length L5 can be 1 mm, but is not limited to this.

[0081] at the same time, Figure 11 The top view of the support member 13 is shown in order to clearly illustrate its structure. Figure 11 No sealing strip 14 is provided in the first groove 131 , but it is conceivable that a sealing strip 14 may be provided in the first groove 131 .

[0082] This arrangement can effectively prevent the blocking strip 14 from damaging the first groove 131 structure in the first direction X, and while sliding out of the first groove 131 , it can ensure that the blocking strip 14 has a good effect of preventing sand and environmental dirt from entering the folding structure 10 .

[0083] In some embodiments, Figure 12 What is shown is a bottom view of the bottom 111 of the main shaft member 11. Figure 1 and Figure 12 As shown, each attraction portion 113 includes a second groove 114 and an attraction material 115 fixed in the second groove 114. The second groove 114 is located on the side of the main shaft 11 facing the support member 13. The attraction material 115 and the second groove 114 have the same size. The second groove 114 extends along the extension direction of the main shaft 11.

[0084] As mentioned above, the extension direction of the main shaft 11 may be the first direction X. The second groove 114 extends along the extension direction of the main shaft 11 , that is, the second groove 114 extends along the first direction X.

[0085] It should be noted that the same size of the attraction material 115 and the second groove 114 does not require that the sizes of the attraction material 115 and the second groove 114 are exactly the same. As long as the sizes of the attraction material 115 and the second groove 114 are the same within the expected tolerance range, the attraction material 115 and the second groove 114 can be considered to have the same size.

[0086] With such arrangement, the suction portion 113 can be used to specifically attract the sealing strip 14 to seal the gap between the main shaft 11 and the support member 13, thereby specifically preventing dirt in the environment including gravel from entering the folding structure 10 through these gaps. Furthermore, it can be specifically prevented that dirt in the environment including gravel affects the normal operation and service life of the folding structure 10.

[0087] In some embodiments, Figure 13 What is shown is a bottom view of another type of main shaft member 11. Figure 1 and Figure 13 As shown, each suction portion 113 includes a plurality of second grooves 114 and a suction material 115 fixed within the second grooves 114. The second grooves 114 are located on the side of the main shaft 11 facing the support member 13. The suction material 115 and the second grooves 114 have the same size. The second grooves 114 extend along the extension direction of the main shaft 11. The second grooves 114 included in the same suction portion 113 are arranged sequentially along the extension direction of the main shaft 11.

[0088] As shown above, the extension direction of the main shaft 11 can be the first direction X. The second grooves 114 of the same attraction portion 113 are arranged in sequence along the extension direction of the main shaft 11, that is, the second grooves 114 of the same attraction portion 113 are arranged in sequence along the first direction X. Moreover, the order in which the second grooves 114 are arranged in sequence along the first direction X can be the order in which the second grooves 114 are arranged in sequence along the first direction X. Figure 13 The same intervals G1 shown in FIG are arranged in sequence, but are not limited thereto.

[0089] Similarly, the fact that the attraction material 115 and the second groove 114 are the same in size does not require that the attraction material 115 and the second groove 114 are exactly the same in size. As long as the sizes of the attraction material 115 and the second groove 114 are the same within the expected tolerance range, the attraction material 115 and the second groove 114 can be considered to be the same in size.

[0090] With this arrangement, the suction sealing strip 14 can be specifically implemented through the suction portion 113 to seal the gap between the main shaft 11 and the support member 13, while saving the use of the suction material 115 and reducing production costs. In addition, since the overall area of ​​the second groove 114 is reduced, the structural strength of the main shaft 11 can be improved. At the same time, since the overall area of ​​the second groove 114 is reduced, space can be reserved for the arrangement of other components that may be installed. Therefore, while specifically preventing dirt in the environment, including gravel, from affecting the normal operation and service life of the folding structure 10, it is possible to reduce production costs, improve the structural strength of the main shaft 11, and reserve space for the arrangement of other components that may be installed.

[0091] In some embodiments, the attraction material 115 may specifically include: bonded NdFeB, sintered NdFeB, injection molded NdFeB, sintered ferrite, rubber magnet, AlNiCo or SmCo, but is not limited thereto.

[0092] In some embodiments, the linear distance between adjacent suction parts 113 is greater than or equal to 1 mm. Specifically, the linear distance between adjacent suction parts 113 may be 1 mm, or the linear distance between adjacent suction parts 113 may be 2 mm, or the linear distance between adjacent suction parts 113 may be 3 mm, or the linear distance between adjacent suction parts 113 may be 4 mm, or the linear distance between adjacent suction parts 113 may be 5 mm, but the present invention is not limited thereto.

[0093] The present application also provides a folding display device, comprising any of the folding structures 10 described above.

[0094] The above embodiments of the present application can complement each other if no conflict occurs.
