Fig. 5 is a schematic structural diagram of a flexible screen of the flexible screen attaching device according to the second embodiment of the present invention before attaching the flexible screen to the curved cover plate. Fig. 6 is a schematic structural diagram of an adjusting assembly of a flexible screen attaching apparatus according to a second embodiment of the present invention.
Referring to fig. 4 to 6, on the basis of the first embodiment, a second embodiment provides a flexible screen attaching device, and compared with the first embodiment, the second embodiment is different from the first embodiment in that: the pressure regulating member has a different structure.
The first pressing member 51 is an elastic connector 54.
As an achievable embodiment, a second pressing part 56 is arranged between the elastic connecting part 54 and the supporting part 30, and one side of the second pressing part 56 close to the supporting part 30 forms a pressing end; a fixing part 57 is arranged on one side of the second pressing part 56, which faces away from the supporting part 30; the elastic connecting pieces 54 are arranged at intervals between the second pressing piece 56 and the fixing piece 57; the second pressing member 56 is a flexible member.
As an implementable embodiment, the pressure adjustment member further includes a second pressure detection member 55, the second pressure detection member 55 being disposed between the elastic connection member 54 and the second pressing member 56.
As an achievable embodiment, the second pressure detecting element 55 may be a pressure sensor, the elastic connecting element 54 may be an air bag, and the deformation amount of the elastic connecting element 54 is changed by adjusting the pressure of the air inside the air bag, thereby changing the pressing pressure applied to the second pressing element 56. The elastic connecting member 54 may also be a liquid bag, and the deformation amount of the elastic connecting member 54 is changed by adjusting the pressure of the liquid inside the liquid bag, thereby changing the pressing pressure applied to the second pressing member 56. The elastic connecting member 54 may also be an electromagnetic assembly, and the electromagnetic assembly includes a first magnetic member and a second magnetic member, wherein the first magnetic member is fixedly disposed on the fixing member 57, and the second magnetic member is fixedly disposed on the second pressing member 56, and the pressing pressure applied to the second pressing member 56 is changed by adjusting the magnitude of the magnetic force between the first magnetic member and the second magnetic member. The elastic connecting member 54 may also be a spring, and the resilient force is adjusted by replacing the spring with a different stiffness coefficient, so as to change the deformation amount of the elastic connecting member 54, and finally change the pressing force applied to the second pressing member 56.
It should be noted that, the elastic connecting member 54 deforms to apply abutting pressure to the second abutting member 56 and the supporting member 30, so that the supporting member 30 elastically deforms in a direction approaching the flexible screen 10, and the flexible screen 10 is attached to the curved cover plate 20; the second pressure detecting element 55 of the pressure adjusting element is used for acquiring the magnitude of the abutting pressure, determining the fitting effect of the flexible screen 10 and the curved surface cover plate 20 according to the magnitude of the abutting pressure, and adjusting the elastic force of the elastic connecting element 54 according to the fitting effect to adjust the abutting pressure, so that the whole area of the fitting surface of the flexible screen 10 and the curved surface cover plate 20 has a good fitting effect.
Specifically, the second pressing member 56 may be made of silicone, rubber, or other resin material, and should have a deformation capability. The specific material of the supporting member 30 is not limited in this embodiment.

Referring to fig. 4 to 6, a second embodiment provides a flexible screen attaching device, and compared with the first embodiment, the second embodiment further has the following differences: the pressure adjustment member loads the support member 30 in a different manner.
It should be noted that in the first embodiment, the pressure adjusting member is loaded on the supporting member 30 in a point contact manner, which is more favorable for rapidly adjusting the local pressure, while in the second embodiment, the pressure adjusting member is loaded on the supporting member 30 in a surface contact manner, which is more favorable for protecting the supporting member 30 from being damaged due to sudden pressure change.
It should be noted that, by setting the elastic strength of the second elastic connecting element that applies the abutting pressure to the arc-shaped extending section of the second abutting member 56 to be greater than the elastic strength of the first elastic connecting element that applies the abutting pressure to the straight-line extending section of the second abutting member 56, when the second elastic connecting element and the first elastic connecting element have the same deformation amount, the second elastic connecting element can provide a greater abutting pressure. The problem of the flexion of flexible screen 10 for the plane portion of flexible screen 10, easily because of the insufficient curved surface laminating part that leads to flexible screen 10 and curved surface apron 20 has the clearance, can't realize closely laminating is solved.
Further, the support member 30 includes a flat portion and a bent portion; the planar segment has a contact area with the adjustment assembly 50 that is greater than 60% of the area of the planar segment. By setting the contact area of the adjustment assembly 50 and the planar portion of the support 30 to be greater than 60% of the area of the planar portion, it is advantageous to achieve accurate adjustment of the local pressure of the planar portion of the support 30. To further improve the accuracy of the adjustment of the local pressure of the flat portion of the support 30, the contact area between the adjustment assembly 50 and the flat portion of the support 30 may be set to be greater than 80% of the area of the flat portion. In practical use, the ratio of the contact area between the flat portion of the support 30 and the adjusting assembly 50 to the area of the flat portion can be adjusted by the user as required within the above range, for example, 85%, 90% or 95%, and the present embodiment does not limit the specific value.
The contact area of the bending part and the adjusting component 50 is larger than 70% of the area of the bending part. The contact area of the adjusting component 50 and the bending part of the supporting piece 30 is set to be more than 70% of the area of the bending part; the accurate adjustment of the local pressure of the bending part of the supporting piece 30 is facilitated. In order to further improve the adjustment precision of the local pressure of the bending part of the support member 30, the contact area between the adjustment assembly 50 and the bending part of the support member 30 may be set to be greater than 95% of the area of the bending part.

The ratio of the contact area of the bending portion to the adjusting assembly 50 to the area of the bending portion is larger than the ratio of the contact area of the planar portion to the area of the adjusting assembly 50 to the area of the planar portion.
It should be noted that, by setting the ratio of the contact area of the adjusting assembly 50 and the bent portion of the support 30 to the area of the bent portion to be greater than the ratio of the contact area of the adjusting assembly 50 and the planar portion of the support 30 to the area of the planar portion, the adjustment of the local pressure of the bent portion, which is more likely to cause poor fitting, can be more accurate than that of the planar portion.
In the above-described flexible screen attaching apparatus, the thickness of the supporting member 30 is optionally in the range of 10 to 50 mm.
It should be noted that, when the thickness of the supporting member 30 is in the range of h1 and h1 is less than 10mm, the supporting member 30 is too thin to bear the flexible screen 10 and/or damage to the flexible screen 10 is easily caused. When h1 is greater than 50mm, the support 30 is too thick to elastically deform, thereby affecting the fit between the flexible screen 10 and the curved cover plate 20. Therefore, in practical use, the thickness of the supporting member 30 can be adjusted by the user within the above range according to the requirement, for example, 20mm, 30mm or 40mm, and the embodiment is not limited to this specific value.
Other technical features are the same as those of the first embodiment and can achieve the same technical effects, and are not described in detail herein.
