Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
Flexible displays backboard preparation method as shown in Figure 1, Figure 2, Figure 3 shows, comprises loading plate 1, comprises the following steps:
A, choose loading plate 1 and connecting plate 2, selected loading plate 1 and connecting plate 2 are slab construction;
B, determine to calculate the loading plate arc radius R of loading plate 1 for installing the spacing of the loading plate installing hole 11 of trip bolt 3 on loading plate 1 according to described loading plate arc radius R, and equally spacedly on loading plate 1 process described loading plate installing hole 11;
C, determine the distance between plates h at interval between loading plate 1 and connecting plate 2, connecting plate arc radius (R+h) is determined according to described distance between plates h, calculate for installing the spacing of the connecting plate installing hole 21 of trip bolt 3 on connecting plate 2 according to described connecting plate arc radius (R+h), and equally spacedly on connecting plate 2 process described connecting plate installing hole 21;
D, trip bolt 3 is set on the loading plate installing hole 11 of loading plate 1 and the connecting plate installing hole 21 of connecting plate 2, the spacing of guarantee loading plate 1 and connecting plate 2 is distance between plates h, by frock and fastener and trip bolt 3 and clamp nut by loading plate 1 and connecting plate 2 fixing firm, loading plate 1 and connecting plate 2 naturally-occurring bend and obtain loading plate 1 curved surface that subsequent corrosion is loading plate arc radius R.
The present invention, in order to solve the problem of loading plate 1 curved surface resilience, first contemplates the design be fixed with the loading plate 1 that connecting plate 2 has been curved surface.But, when the present invention states design in realization, make use of mechanical relationship between connecting plate 2, loading plate 1 and trip bolt 3 cleverly to achieve the effect of bending loading plate 1.Concrete step is such: first, chooses the loading plate 1 and connecting plate 2 that are slab construction; Then, determine radius of curvature i.e. the loading plate arc radius R of loading plate 1 curved surface that finally will be formed, in conjunction with the manufacture craft of curved surface, make the spacing of loading plate installing hole 11, loading plate installing hole 11 here inserts trip bolt 3 for the later stage and carries out bending; Next, general meeting leaves distance between plates h between loading plate 1 and connecting plate 2, and (general h is not equal to 0, facilitate bending technique to leave gap), board spacing h, connecting plate arc radius (R+h) can be obtained, as shown in Figure 2, because connecting plate arc radius (R+h) is greater than loading plate arc radius R, therefore the spacing being arranged at the connecting plate installing hole 21 on connecting plate 2 is also the spacing being greater than the loading plate installing hole 11 be arranged on loading plate 1.Exactly because such pitch difference, trip bolt 3 is being set on the loading plate installing hole 11 of loading plate 1 and the connecting plate installing hole 21 of connecting plate 2, through clamp nut, loading plate 1 and connecting plate 2 are fixed firmly again, just must there is a phenomenon, namely all can there is bending and become curved surface in loading plate 1 and connecting plate 2, the difference that its principle make use of the pitch of holes in two described holes realizes, be aided with the mechanical function of clamp nut and trip bolt 3 again, the curved surface that loading plate 1 is formed is nature not only, and it is firmly lasting, the ingenious part of the present invention's design is just this.
Specific to flexible displays back board structure, the connecting plate 2 comprise loading plate 1, being fixedly connected with by trip bolt 3 with clamp nut with loading plate 1, described loading plate 1 is for curved surface and loading plate 1 subsequent corrosion is loading plate arc radius R, described connecting plate 2 be curved surface and with loading plate 1 place curved surface concentric, spacing between loading plate 1 and connecting plate 2 is distance between plates h, connecting plate 2 subsequent corrosion is connecting plate arc radius (R+h), and trip bolt 3 is arranged in loading plate installing hole 11 and connecting plate installing hole 21.Loading plate 1 is fixedly connected with together with clamp nut by trip bolt 3 with connecting plate 2 again, due to the spacing of loading plate installing hole 11 and the different of connecting plate installing hole 21, the natural torsion of loading plate 1 and connecting plate 2 must have been there is, thus the radius of curvature defining loading plate 1 is loading plate arc radius R, and the radius of curvature of connecting plate 2 is for holding connecting plate arc radius (R+h).
In view of the feature of such scheme, for the sheet material of loading plate 1, generally choose corrosion resistant plate, cold-rolled steel sheet, plated steel sheet, hot-dip galvanizing sheet steel, Al-Zn coated steel or aluminium alloy plate.Same, for the sheet material of connecting plate 2, also corrosion resistant plate, cold-rolled steel sheet, plated steel sheet, hot-dip galvanizing sheet steel, Al-Zn coated steel or aluminium alloy plate can be chosen.Choosing above-mentioned sheet material is summary based on production practices, not only can well ensure curve quality, also can reduce the material cost making curved surface.
