Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a schematic cross-sectional view of a bendable supporting element according to an embodiment of the present application; FIG. 2 is a schematic view of the embodiment of the present application in FIG. 1 showing the bendable support in an unfolded state; FIG. 3 is a schematic view of the embodiment of the present application shown in FIG. 1 illustrating an expanded state of the bendable support at another viewing angle. The bendable support 10 may include: the adhesive film comprises a metal layer 101 provided with a plurality of through holes 104, a first adhesive layer 105 arranged on a first side of the metal layer 101, and a second adhesive layer 106 arranged on a second side, opposite to the first side, of the metal layer 101. The first adhesive layer 105 is connected with the second adhesive layer 106 through the through hole 104; that is, an adhesive material is also provided in the through-hole 104, thereby connecting the first adhesive layer 105 and the second adhesive layer 106 together. The materials of the first adhesive layer 105 and the second adhesive layer 106 may be the same as the adhesive material in the through-hole 104. A plurality of first grooves 102 are formed on a first side of the metal layer 101. The first grooves 102 are communicated with each other through a first communicating groove 1021; that is to say, the first side of the metal layer 101 is provided with a plurality of first connecting grooves 1021, and every two first grooves 102 are connected through one first connecting groove 1021. The second side of the metal layer 101 is formed with a plurality of second grooves 103. The second grooves 103 communicate with each other through the second communication grooves 1031; that is, the second side of the metal layer 101 is provided with a plurality of second communication grooves 1031, and every two second recesses 103 are connected by one second communication groove 1031. Each through hole 104 communicates one first groove 102 and one second groove 103. Each through hole 104 and the first groove 102 and the second groove 103 communicated therewith have the same central axis.
The material of the metal layer 101 may be stainless steel, or steel, iron, or other suitable metals or alloys, which are not limited herein. The metal layer 101 has good flexibility, and the metal layer may be a bendable structure. The metal layer 101 may be rectangular in shape when expanded, square in shape, or any other suitable shape. The first adhesive layer 105 and the second adhesive layer 106 may be made of hot melt adhesive, and are used for fixing the metal layer 101. The shape of the first adhesive layer 105 and the second adhesive layer 106 is adapted to the shape of the metal layer 101. A first adhesive layer 105 and a second adhesive layer 106 are respectively adhered to opposite sides of the metal layer 101.
It is understood that the through hole 104 is formed in the metal layer 101 to connect the first adhesive layer 105 and the second adhesive layer 106 together, so that when the metal layer 101 is bent, the first adhesive layer 105, the second adhesive layer 106 and the metal layer 101 are mutually constrained, and the pulling force that the first adhesive layer 105 and the second adhesive layer 106 are intended to be separated is resisted, so as to achieve the purpose that the first adhesive layer 105, the second adhesive layer 106 and the metal layer 101 cannot be separated.
Furthermore, a first groove 102 is formed in the first side of the metal layer 101, a second groove 103 is formed in the second side of the metal layer 101, and the first groove 102 and the second groove 103 are correspondingly arranged to reduce the thickness of the metal layer 101, so that stress is reduced when the metal layer 101 is bent, stress difference between the first adhesive layer 105, the second adhesive layer 106 and the metal layer 101 is reduced, and separation of the first adhesive layer 105, the second adhesive layer 106 and the metal layer 101 is avoided. Wherein the first adhesive layer 105 and the second adhesive layer 106 are connected through the through hole 104. That is, the first adhesive layer 105 and the second adhesive layer 106 may be a unitary structure.
It is understood that the first recess 102 and the second recess 103 are correspondingly disposed, which means that a projection of the first recess 102 on the metal layer 101 in a direction perpendicular to the metal layer 101 coincides with a projection of the second recess 103 on the metal layer 101 in a direction perpendicular to the metal layer 101. A via hole 104 is provided on the metal layer 101 projecting the overlapping portion so that the via hole 104 can communicate the first groove 102 and the second groove 103.
In some embodiments, hot melt adhesive is added to both sides of the metal layer 101 and cooled to solidify while the metal layer 101 is in the bent state. When the hot melt adhesive is in a liquid state, the hot melt adhesive completely fills the first grooves 102, the second grooves 103 and the through holes 104 to form the first adhesive layers 105 and the second adhesive layers 106, so that the first adhesive layers 105 and the second adhesive layers 106 are integrally formed. Because the solidified first adhesive layer 105 and the solidified second adhesive layer 106 are also in a bent state, and have a tendency of maintaining this bent state, the first adhesive layer 105 and the second adhesive layer 106 can counteract the stress of flattening, so that the bendable support member 10 is more labor-saving and smooth when bent.
The metal layer 101 has a plurality of first connection grooves 1021 on a first side thereof, and the metal layer 101 has a plurality of second connection grooves 1031 on a second side thereof. The first communicating grooves 1021 function to communicate all the first grooves 102, and the second communicating grooves 1031 function to communicate all the second grooves 103, so that the hot melt adhesive can smoothly flow among the first grooves 102, the second grooves 103, the through holes 104, the first communicating grooves 1021, and the second communicating grooves 1031 in the molding process of the first adhesive layer 105 and the second adhesive layer 106. In addition, the arrangement of the first connecting groove 1021 and the second connecting groove 1031 can make the metal layer 101 more smooth and easy when being bent, and the stress is more even, which is not easy to cause the breakage of the metal layer 101.
Referring to fig. 4, fig. 4 isbase:Sub>A cross-sectional view of the bendable supporting element atbase:Sub>A-base:Sub>A in the embodiment of fig. 2. In an embodiment, the size of the first groove 102 is larger than that of the second groove 103 in the length direction and/or the width direction of the metal layer 101. It is understood that the metal layer 101 may be divided into a length direction and a width direction, and the dimension B of the first groove 102 may be greater than the dimension C of the second groove 103 in the length direction; or the size of the first groove 102 may be larger than the size of the second groove 103 in the width direction; alternatively, the size of the first groove 102 is larger than the size of the second groove 103 in both the length direction and the width direction.
In an embodiment, the through-hole 104, the first groove 102 and the second groove 103 each have a square cross-section. In another embodiment, the through hole 104, the first groove 102 and the second groove 103 may also have a cross section of a circle, a triangle or other suitable shape, which is not limited herein.
The first grooves 102, the second grooves 103 and the through holes 104 may be arranged in rows and columns. Specifically, the first grooves 102, the second grooves 103, and the through holes 104 are arranged in an array on the metal layer 101, that is, the pitches between the adjacent first grooves 102 in the length direction are equal, and the pitches between the adjacent first grooves 102 in the width direction are equal. The arrangement of the second groove 103 and the through hole 104 is the same as that of the first groove 102, and the description thereof is omitted.
Further, in the longitudinal direction and the width direction of the metal layer 101, the through holes 104 are arranged in a matrix with the first communicating groove 1021, and the through holes 104 are arranged in a matrix with the second communicating groove 1031.
In another embodiment, the first grooves 102, the second grooves 103 and the through holes 104 may not be arranged in rows and columns, and each through hole 104 can communicate one first groove 102 and one second groove 103. That is, the first grooves 102, the second grooves 103, and the through holes 104 may be irregularly arranged, and distances between adjacent first grooves 102, second grooves 103, or through holes 104 may be different.
The first adhesive layer 105 includes two portions, one of which is disposed in the first recess 102 and the first connecting groove 1021, and the other of which completely covers the first side, and the second adhesive layer 106 includes two portions, one of which is disposed in the second recess 103 and the second connecting groove 1031, and the other of which completely covers the second side.
It will be appreciated that during the molding of the first adhesive layer 105, not only is the first groove 102 completely filled, but also the first side of the metal layer 101 is completely covered. If the first adhesive layer 105 does not completely cover the first side of the metal layer 101, the metal layer 101 may be exposed, and other components may be damaged. The first side of the metal layer 101 refers to the side of the metal layer 101 where the first recess 102 is opened.
During the molding process of the second adhesive layer 106, the second adhesive layer not only completely fills the second groove 103, but also completely covers the second side of the metal layer 101. If the second adhesive layer 106 does not completely cover the second side of the metal layer 101, the metal layer 101 may be exposed, thereby causing damage to other components. The second side of the metal layer 101 refers to the side of the metal layer 101 where the second recess 103 is opened.
Please continue to refer to fig. 4. The bendable support 10 further includes an annular rim portion 107 extending in a thickness direction of the metal layer 101, a first annular rim 1071 of the annular rim portion 107 extending beyond the first side, and a second annular rim 1072 of the annular rim portion 107 extending beyond the second side. First adhesive layer 105 is flush with first annular edge 1071 and second adhesive layer 106 is flush with second annular edge 1072.
It is to be understood that, during the molding of the first adhesive layer 105, hot melt adhesive is directly injected into the first recess 102, the through-hole 104, and the second recess 103. In order to allow the first adhesive layer 105 to be completely formed, the annular edge portions 107 are provided at the edges of the metal layer 101, so that the first adhesive layer 105 does not continue to extend outward when contacting the annular edge portions 107, and thus the first adhesive layer 105 can be confined between the annular edge portions 107 so that the shape of the first adhesive layer 105 is substantially the same as the shape of the metal layer 101. Also, annular edge portion 107 includes a first annular edge 1071 on the first side, and first annular edge 1071 extends beyond the first side, first adhesive layer 105 being flush with first annular edge 1071.
Similarly, in order to form the second adhesive layer 106 completely, the annular edge portions 107 are provided at the edges of the metal layer 101, so that the second adhesive layer 106 does not extend outward when contacting the annular edge portions 107, and thus the second adhesive layer 106 can be confined between the annular edge portions 107 so that the shape of the second adhesive layer 106 is substantially the same as the shape of the metal layer 101. And annular edge portion 107 includes a second annular edge 1072 on a second side with second annular edge 1072 extending beyond the second side with second adhesive layer 106 flush with second annular edge 1072.
The first adhesive layer 105 and the second adhesive layer 106 are disposed on the metal layer 101 in a bent state of the metal layer 101. Specifically, in order to facilitate bending of the bendable support 10, when the first adhesive layer 105 and the second adhesive layer 106 are formed, the metal layer 101 is bent, and when the metal layer 101 is in a bent state, hot melt adhesive is injected into the metal layer 101, and then the hot melt adhesive is cooled and condensed to form the metal layer. The formed hot melt adhesive is divided into a first adhesive layer 105 and a second adhesive layer 106, and the solidified first adhesive layer 105 and the solidified second adhesive layer 106 are also in a bending state, so that the stress of the first adhesive layer 105 and the stress of the second adhesive layer 106 can offset the stress of the metal layer 101 which is required to be flattened, and the bending is more labor-saving and smooth. That is, since the first adhesive layer 105 and the second adhesive layer 106 are in the bent state during the forming process, a certain force needs to be overcome when the metal layer 101 is flattened, and similarly, when the metal layer 101 is changed from the flattened state to the bent state, the first adhesive layer 105 and the second adhesive layer 106 also provide a certain force for the bending process, so that the bending process is more labor-saving and smoother.
The application provides a bendable support 10, wherein a first groove 102 is formed in a metal layer 101, and a first bonding layer 105 is arranged on one side of the metal layer 101, so that when the bendable support 10 is bent, the stress of the metal layer 101 can be relieved, and the stress difference between the first bonding layer 105 and the metal layer 101 is reduced; moreover, the metal layer 101 and the first adhesive layer 105 are mutually constrained, and the pulling force of the first adhesive layer 105 to be separated is resisted, so that the metal layer 101 and the first adhesive layer 105 are difficult to separate, and the bending of the bendable supporting element 10 is more labor-saving and smooth.
