In this embodiment, the distance between the intersection line and the top side 321 is smaller, so that the height of the protruding plate 320 protruding from the substrate 310 is smaller, and the dimension of the top frame 110 in the length direction of the electronic device 10 is smaller, which is beneficial to improving the appearance expression of the electronic device 10.

If the first transition surface 321a is formed by rounding at the intersection of the top side 321 and the first outer surface 324 and the first transition surface 321a is a 2.5D arc, the first transition surface 321a has a width D2, D2 is 0.8mm to 1.6mm, preferably 1.6mm, as shown in fig. 13. It is understood that the width d2 of the first transition surface 321a is the width of the orthographic projection of the first transition surface 321a on the first reference plane. When the arc surface is machined, glass close to the arc surface is damaged, so a distance needs to be reserved between the intersection line and the first transition surface 321a as a safety distance d3, and d3 is not less than 0.6 mm. Therefore, when the intersection of the top side 321 and the first outer surface 324 is rounded to form a 2.5D transition arc, the minimum distance D1 between the intersection line formed by the intersection of the viewing angle of the camera module 400 and the first outer surface 324 and the top side 321 is D2+ D3, and the minimum value of D1 ranges from 1.4mm to 2.2mm, which results in a larger dimension between the intersection line and the top side 321, so that the height L1 of the protruding board 320 protruding from the substrate 310 is larger in size, and the top frame 110 needs to be opened in the groove 111 with a larger dimension in the length direction of the electronic device 10 to accommodate the protruding board 320, resulting in a longer distance from the top end of the top frame 110 to the displayable region of the display screen 200, so that the top frame 110 has a larger dimension in the length direction of the electronic device 10, thereby reducing the appearance expressive force of the electronic device 10.

As shown in fig. 2 and 10, in an embodiment, the intersection of the top side 321 and the first outer surface 324 is chamfered to form a first transition surface 321a, and the first transition surface 321a is a plane and is connected between the top side 321 and the first outer surface 324 in an inclined manner. It is understood that the first transition surface 321a may also be curved by rounding. The first transition surface 321a may increase the strength of the cover plate 300 and avoid stress concentration at the intersection of the top side 321 and the first outer surface 324. In the present embodiment, the width d2 of the first transition surface 321a is 0.1mm to 0.8 mm. The safety distance d3 is not less than 0.1mm and not more than 0.6mm, the minimum distance d1 between the intersection line formed by the intersection of the field angle of the camera module 400 and the first outer surface 324 and the top side 321 is d2+ d3, and the minimum value of d1 ranges from 0.2mm to 1.4 mm. For example, if the width d2 of the first transition surface 321a is 0.15mm and the safety distance d3 is 0.25mm, the distance d1 between the intersection line and the top side 321 is 0.4 mm. In this embodiment, the oblique plane formed by the bevel at the intersection of the top side 321 and the first outer surface 324 is used as the first transition surface 321a, which can enhance the strength of the cover plate 300, and avoid the problem that the height L1 of the protruding board 320 protruding the base plate 310 is too large when the first transition surface 321a is a cambered surface. As shown in fig. 3 and 10, in an embodiment, the camera module 400 includes an optical axis, and the distance L2 between the optical axis and the displayable region of the display screen 200 is 3.4 mm. It is understood that the electronic device 10 may use camera modules 400 of different sizes, and the value of L2 may vary.

As shown in fig. 2 and 6, in an embodiment, the left side surface 322, the right side surface 323, and the first outer surface 324 of the convex plate 320 smoothly transition through a 2.5D arc to form a second transition surface 322a, and the width of the second transition surface 322a is 0.8mm to 1.6 mm. It will be appreciated that the width of the second transition surface 322a is the width of the orthographic projection of the second transition surface 322a on the first reference plane. As shown in fig. 5 and 6, in an embodiment, the substrate 310 includes a left end surface 312 and a right end surface 314 disposed opposite to each other, a bottom end surface 313 disposed opposite to the top end surface 311, and a second outer surface 315 facing away from the display screen 200, wherein the second outer surface 315 is coplanar with the first outer surface 324. The left end face 312 is connected to one end of the top end face 311 and the bottom end face 313, and the right end face 314 is connected to the other end of the top end face 311 and the bottom end face 313; the top end surface 311, the bottom end surface 313, the left end surface 312 and the right end surface 314 are located on the periphery of the second outer surface 315, and smoothly transition with the second outer surface 315 through a 2.5D radian to form a third transition surface 311a, and the width of the third transition surface 311a is 0.8 mm-1.6 mm. It is understood that the width of the third transition surface 311a is the width of the orthographic projection of the third transition surface 311a on the first reference plane. The second transition surface 322a and the third transition surface 311a can increase the strength of the cover plate 300, so that the cover plate 300 has the characteristics of good hand feeling, breakage resistance, easy point control and the like, and the display screen assembly of the electronic device 10 is more three-dimensional and has an excellent visual effect.

In one embodiment, the electronic device 10 is assembled in the following order: fixing the cover plate 300 and the display screen 200 to the middle frame 100 through a dispensing process, assembling the camera module 400 to the middle frame 100, positioning the length and width directions of the camera module 400 through the middle frame 100, and exposing the lens 411 through the through hole 112; assembling the main board 700 to the middle frame 100; the BTB connector of the camera module 400 is fastened to the motherboard 700; assembling the pressing plate 800 to the middle frame 100 by screws, the pressing plate 800 being located on a side of the main board 700 facing away from the middle plate 150, and pressing the camera module 400 in a thickness direction of the electronic device 10; the battery cover 600 is fastened.

Along with the popularization of the comprehensive screen of the electronic device 10, the camera module 400 is gradually close to the top end of the middle frame 100, so that the distance from the cover plate 300 to the top end of the middle frame 100 is increased, the 2.5D radian of the top edge of the convex plate 320 of the cover plate 300 at the camera module 400 is increased in the size of the convex plate 320 in the length direction of the electronic device 10, the visual height of the top frame 110 is high, and attractiveness is affected. According to the electronic device 10, the 2.5D radian of the top edge of the convex plate 320 is eliminated, so that the top side 321 of the convex plate 320 is perpendicular to the first outer surface 324 or is in transition through chamfering, the height L1 of the convex plate 320 protruding out of the base plate 310 is reduced, the visual height of the top frame 110 is reduced, and the appearance expressive force of the electronic device 10 is improved.
