Of course, the one side surface of the cover plate portion 2 may form an angle with the one side surface of the sub middle frame portion 21 away from the cover plate portion 1.
In some optional embodiments of the present invention, as shown in fig. 1 to 8, the curved line segment is formed as an arc line segment, which is simple in structure and convenient to process. Wherein, the radius of the arc line segment is r, and r satisfies: r is not less than 0.5mm and not more than 4mm, so that the structural diversity of the middle frame part 2 is further ensured on the premise of ensuring convenient processing, the diversified design of the screen cover plate 100 is realized, and the electronic equipment has good design flexibility.
Specifically, as shown in fig. 1-8, the curved line segment is formed as an arc line segment, the central angle of the arc line segment is α, which satisfies that α is larger than or equal to 90 degrees and smaller than or equal to 180 degrees, and the structural diversity of the middle frame part 2 is further ensured on the premise of ensuring the convenience of processing, so that the diversified design of the screen cover plate 100 is realized, and the electronic device has good design flexibility.
For example, in the example of fig. 1 to 8, the curved line segment is formed as a circular arc line segment, the central angle α corresponding to the circular arc line segment is 180 °, on the cross section of the sub middle frame portion 21, both ends of the circular arc line segment may be tangent to the projection of the inner side surface of the cover plate portion 1 and the projection of one side surface of the sub middle frame portion 21 far away from the cover plate portion 1, that is, on the cross section of the sub middle frame portion 21, one circumferential end of the circular arc line segment may be tangent to the projection of the inner side surface of the cover plate portion 1, and the other circumferential end of the circular arc line segment may be tangent to the projection of one side surface of the sub middle frame portion 21 far away from the cover plate portion 1, thereby further ensuring the neat and beautiful appearance of the screen.

Alternatively, as shown in fig. 5 to 8, the curved section protrudes toward the direction close to the central axis 10 of the cover plate, so that the width of the sub middle frame portion 21 increases first and then decreases in the thickness direction of the cover plate portion 1, and the widest position of the sub middle frame portion 21 may be located on the thickness central plane of the sub middle frame portion 21 or offset from the thickness central plane of the sub middle frame portion 21; or, as shown in fig. 1 to 4, the curved section is recessed toward a direction away from the central axis 10 of the cover plate, so that the width of the sub middle frame portion 21 decreases first and then increases in the thickness direction of the cover plate portion 1, the narrowest position of the sub middle frame portion 21 may be located on the thickness central plane of the sub middle frame portion 21 or may be offset from the thickness central plane of the sub middle frame portion 21, and the display module may be attached to the screen cover plate 100, especially to the inner wall 20 of the sub middle frame portion, more closely, so that the light and shadow effect presented by the electronic device is better.
Here, the "width of the sub middle frame portion 21" may refer to a width of the sub middle frame portion 21 in a radial direction of the cover plate portion 1; the "thickness center plane of the sub middle frame portion 21" refers to a center plane in the thickness direction of the sub middle frame portion 21, and the thickness direction of the sub middle frame portion 21 is parallel to the thickness direction of the cover plate portion 1.
Of course, the curved line segment may also be formed as an elliptical arc line segment, a hyperbolic line segment, or the like, without being limited thereto.
In other optional embodiments of the present invention, as shown in fig. 9 and 10, the curve segment is formed as a combination of at least one straight line segment and at least one arc segment, and is tangent between the straight line segment and the adjacent arc segment, so that the curve segment is G1 continuous, thereby further ensuring the structural diversity of the middle frame part 2, and realizing the diversified design of the screen cover plate 100.
It is understood that the arc segment may be a circular arc segment, or an elliptical arc segment; the number of the straight line segments and the number of the arc segments can be specifically set according to actual requirements, so that the actual application can be better met.
For example, in the example of fig. 9 and 10, there are one straight line segment and one arc segment, that is, there are one straight line segment and one arc segment, and the arc segment and the straight line segment are sequentially arranged in a direction from the cover plate portion toward the middle frame portion, that is, a part of the inner wall of the sub middle frame portion 21 corresponding to the arc segment may be directly connected to the inner side surface of the cover plate portion 1, and a part of the inner wall of the sub middle frame portion 21 corresponding to the straight line segment may be directly connected to a side surface of the sub middle frame portion 21 away from the cover plate portion 1. From this, sub-middle frame portion 21 simple structure, reasonable, the butt fusion between frame portion 2 and the apron portion 1 in being convenient for 100 structural design of screen apron is reasonable, is convenient for cooperate better with display module assembly.
Optionally, the width of the arc segment in the left-right direction is 1 mm-10 mm (inclusive), and the width of the arc segment in the front-back direction is 0.5 mm-7 mm (inclusive), so that the screen cover 100 has a simple and reasonable structure and is convenient to process.
