It should be noted that the terms "first", "second" and "third" in the present invention are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

Accordingly, the middle frame 200 includes a first side frame 210, a second side frame 220, a third side frame 230 and a fourth side frame 240, wherein the first side frame 210, the second side frame 220, the third side frame 230 and the fourth side frame 240 are connected end to end in sequence. And the first side frame 210, the second side frame 220, the third side frame 230, and the fourth side frame 240 correspond to the first bending portion 121, the second bending portion 122, the third bending portion 123, and the fourth bending portion 124, respectively.

Referring to fig. 3 to 5 and fig. 7 and 8 together, fig. 7 is a schematic sectional view of the display panel cover plate at a-a in fig. 6; FIG. 8 is an enlarged view of a portion of the structure at B in FIG. 3; in the present embodiment, the bending depth D1 of the first bending portion 121 connected to the first side 111 of the body portion 110 is smaller than the bending depth D2 of the bending portions (the second bending portion 122, the third bending portion 123, and the fourth bending portion 124) connected to the other sides (the third bending portion 123 in the figure). The bending depth of the bent portion referred to herein means a distance between an end of the bent portion and an inner side surface of the body portion 110. Wherein, the bending depths of the second, third and

fourth bending parts

122, 123 and 124 may be set to be the same.

Alternatively, the bending depth D1 of the first bending part 121 connected to the first side 111 of the main body part 110 may be in a range of 1.5 to 3mm, and specifically may be 1.5mm, 1.6mm, 1.8mm, 2.0mm, 2.5mm, 2.8mm, 3mm, or the like. In the present embodiment, the bending depth D1 of the first bending part 121 connected to the first side 111 of the body part 110 is 1-2mm smaller than the bending depth D2 of the bending part connected to the other sides; accordingly, the thickness of the first side frame 210 of the middle frame 200 at the position opposite to the first bending part 121 connected to the first side 111 of the body part 110 is 1-2mm greater than that of the second, third and

fourth side frames

220, 230 and 240; the thickness of the first side frame 210 is 3-5mm, and may be 3mm, 3.2mm, 3.5mm, 4mm, 4.5mm, 4.8mm, 5mm, or the like.

Referring to fig. 9, fig. 9 is a schematic cross-sectional view taken at C-C in fig. 2. The whole machine four-side bending scheme becomes a new development trend, and for the current verification situation, the minimum curvature radius of the inner surface of the bending part 120 of the display screen cover plate 100 is about 6mm generally, and in order to optimize the whole appearance effect of the whole machine, the display screen module 400 is expected to be attached to the display screen cover plate 100, and the black edge display width of the front surface of the display screen module is the minimum. The display screen module 400 may be an OLED flexible display screen.

Accordingly, the thickness T1 of the first side frame 210 of the middle frame 200 at the position opposite to the first bending portion 121 connected to the first side 111 of the main body 110 is greater than the thickness T2 of the side frames (the second side frame 220, the third side frame 230, and the fourth side frame) of the middle frame at the position opposite to the bending portions connected to the other sides of the main body 110. Wherein, the thicknesses of the second side frame 220, the third side frame 230, and the fourth side frame may be set to be the same.

In this embodiment, the maximum shape of the whole machine circumference is on the side frame structure of the middle frame 200, so the whole machine has better strength, and in the falling process, the side frame structure of the middle frame 200 lands first, so the whole machine has better reliability. Furthermore, in consideration of the antenna layout, if the thickness of the middle frame around the whole device is small (the antenna is generally arranged at the position of the side frame, and the side frame is used for receiving and sending signals), the difficulty is great from the perspective of the antenna (the width is too small, the antenna is not easy to be arranged, and the signal receiving and sending strength is weak). Therefore, in view of the above, in order to consider that the display effect of the display screen module 400 is full and ensure that the antenna can have a better installation position, the scheme in this embodiment provides a new electronic device structure based on this, so that the reliability of the whole device is improved, the signal strength of the antenna (in this embodiment, the antenna can be installed corresponding to the first side frame 210 of the middle frame 200) is not weakened due to the excessively narrow frame, and the appearance effect of the whole device is better.

Referring to fig. 2 and fig. 6, the battery cover 300 of the present embodiment includes a main plate 310 and a bending portion 320; the bending portion 320 extends along the edge of the main board 310 and bends and extends toward the middle frame 200. Optionally, in this embodiment, the bending portion 320 extends along the circumferential edge of the main board 310 and bends toward the same side surface of the main board 310. Likewise, the main board body 310 may have a rectangular flat structure.

Referring to fig. 10, fig. 10 is a schematic cross-sectional view of the battery cover at F-F in fig. 2, wherein a bending depth D3 of a first bending portion 321 disposed opposite to the first side 111 of the main portion 110 of the battery cover 300 and the display cover 100 is smaller than a bending depth D4 of a bending portion (a third bending portion 323 in the figure) disposed opposite to the other sides. The bending depth D3 of the bending portion (i.e., the first bending portion 321) of the battery cover 300 opposite to the first side 111 of the main body portion 110 of the display cover 100 is 1.5-3mm, and specifically may be 1.5mm, 1.6mm, 1.8mm, 2.0mm, 2.5mm, 2.8mm, 3mm, and the like. It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.

Optionally, the bending depth D3 of the first bending part 321 disposed opposite to the first side 111 of the main body part 110 of the display cover panel 100 of the battery cover panel 300 is 1-2mm smaller than the bending depth D4 of the bending part disposed opposite to the other sides. With continued reference to fig. 3 and 8, the bending portion 120 of the display cover 100 and the bending portion 320 of the battery cover 300 may be disposed symmetrically with respect to the middle frame 200, and the disposition structure may make the side appearance of the whole device have a symmetrical aesthetic feeling, and the whole shape is more rounded.

Wherein, for the laminating effect of guaranteeing the four sides curve at the fillet position, this scheme can design the minimum curvature radius of the internal surface of display screen apron 100 flexion 120 and be 6 mm. Further, in order to ensure that the fillet position has the display effect that the fillet is excessively smooth and uniform, the maximum bending depth of the display screen cover plate 100 can be designed within 3.5mm, that is, the positions of other bending parts except the first bending part 121 can be designed between 2.5mm and 3.5 mm. In addition, in order to ensure the signal strength of the antenna, in the embodiment of the present application, the main antenna of the electronic device may be close to the head position (the top of the display state of the display screen of the electronic device) to be out of the line, and the middle frame thickness T1 of the head of the whole electronic device may be defined to be about 3.4mm, and the bending depth of the display screen cover plate 100 at the head position (i.e., the first bending portion 121 connected to the first side 111 of the main body portion 110) may be designed to be about 2-2.5 mm. In order to minimize the black edge on the front side, the bending depth of the display screen cover plate 100 on the left side, the right side and the bottom can be designed to be about 3.5mm, the bending depth of the display screen cover plate 100 on the bottom (the position corresponding to the third bending part 123) can be designed to be larger, and more bottom wires can be redundant (generally, the width of the bottom black wire is larger than that of the other three sides, so that if the depth of the display screen cover plate 100 is defined to be larger on the bottom, the black edge displayed on the front side is smaller, and the display effect is better); as can be seen from the view of FIG. 3, the head middle frame 200 (the first side frame 210) of the whole machine is thicker, the bottom middle frame and the side surface are consistent in thickness and thinner, and the black edge of the whole machine is smooth and excessive at the position of a fillet; the battery cover plate 300 and the display screen cover plate 100 are symmetrically designed relative to the middle frame 200, and the appearance is attractive.

The above description is only a part of the embodiments of the present invention, and not intended to limit the scope of the present invention, and all equivalent devices or equivalent processes performed by the present invention through the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
