The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure.

The following disclosure provides many different embodiments, or examples, for implementing different features of the disclosure. To simplify the disclosure of the present disclosure, specific example components and arrangements are described below. Of course, they are merely examples and are not intended to limit the present disclosure. Further, the present disclosure may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present disclosure provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

Next, an electronic apparatus 100 according to an embodiment of the present disclosure is described with reference to the drawings.

As shown in fig. 1, an electronic device 100 according to an embodiment of the present disclosure includes: a middle frame 1 and a cover plate 2. In some specific examples, the electronic device 100 includes a screen cover 3 and a back cover 4, and the cover 2 is the back cover 4 and/or the screen cover 3. That is, when the electronic device 100 includes the screen cover 3 and the rear cover 4, at least one of the screen cover 3 and the rear cover 4 may employ the cover 2 of the embodiment of the present disclosure. It is understood that, as shown in fig. 2-4, the screen cover 3 and the rear cover 4 are respectively disposed on the front and rear sides of the middle frame 1, where the front side refers to the display side of the electronic device 100, and the rear side refers to the non-display side of the electronic device 100, and in some embodiments, the rear cover 4 may also be a battery cover.

In addition, it should be noted that the specific type of the electronic device 100 according to the embodiment of the present disclosure is not limited, and for example, the electronic device may be a fixed device, such as a television, a computer, and the like, a portable device, such as a mobile phone, a tablet computer, and the like, and a wearable device, such as a smart watch, a smart necklace, and the like. After the specific type of the electronic device 100 is determined, a person skilled in the art can know other components of the electronic device 100, for example, when the electronic device 100 is a mobile phone, the electronic device 100 may further include a card holder 5, a side key 6, a battery, and the like, which are not described herein.

For simplicity of description, only the electronic device 100 is taken as a mobile phone, and the screen cover 3 is taken as the cover 2 in the embodiment of the disclosure for illustration, and after reading the technical solutions of the disclosure, it is obvious to understand that when the rear cover 4 is the cover 2 in the embodiment of the disclosure and the electronic device 100 is other types of electronic devices except for a mobile phone, further description is omitted.

As shown in fig. 4 and 5, the bezel 1 includes a side bezel 11, the cover 2 includes a cover main body 21 and a cover edge 220, at least a portion of the cover edge 220 is configured as a curved edge 22, that is, the cover edge 220 is disposed around the entire periphery of the contour edge of the cover main body 21, so that the curved edge 22 is disposed at the edge of the cover main body 21, at least a portion of the cover edge 220 is gradually curved toward a direction approaching the side bezel 11 with respect to the cover main body 21, and the at least a portion is the curved edge 22, that is, the curved edge 22 extends in a direction from the display side to the non-display side of the electronic device 100 in a direction away from the cover main body 21.

For example, in the example shown in fig. 5 to 7, the cover plate 2 is provided on the front side of the middle frame 1, the left and right sides of the cover plate 2 are respectively provided with a curved edge 22, the curved edge 22 extends rearward in a direction away from the cover plate main body 21, that is, the curved edge 22 on the left side of the cover plate main body 21 is curved gradually rearward in a direction from right to left, and the curved edge 22 on the right side of the cover plate main body 21 is curved gradually rearward in a direction from left to right.

Referring to fig. 7, the bent edge 22 has a thickness greater than that of the cover plate body 21. That is, the thickness of the bent edge 22 is greater at any position than at any position of the cover main body 21 except for the position where the bent edge 22 is connected to the cover main body 21. From this, thickness through setting up crooked edge 22 is greater than the thickness of apron main part 21 to can guarantee under the thinner condition of the thickness of apron main part 21, crooked edge 22's thickness is thicker, thereby can improve apron 2 at the structural strength of edge bending position, improve electronic equipment 100's anti performance of falling, and can guarantee the holistic frivolousness of apron 2. For example, the cover body 21 may be a generally flat plate structure having a substantially uniform thickness, and the outer surface of the cover body 21 may be planar or substantially planar.

Thus, according to the electronic device 100 of the embodiment of the present disclosure, when the thickness of the cover main body 21 is small, the bent edge 22 can be ensured to have a sufficient thickness, so as to improve the structural strength of the cover 2 at the bent position and improve the anti-falling performance of the electronic device 100.

With the pursuit of high screen ratio, more and more mobile phone manufacturers select a curved screen cover plate, which is generally uniform and light in thickness, for example, the thickness is about 0.5mm or 0.55mm, and the curved screen cover plate is manufactured through a 3D hot bending process to obtain a curved shape of the curved edge 22, however, because the thickness of the screen cover plate is small, the strength of the curved edge 22 is not enough, and the screen breaking risk is increased when the screen cover plate falls. According to the electronic device 100 of the embodiment of the present disclosure, when the thickness of the cover main body 21 is relatively thin, the bent edge 22 can be ensured to have a sufficient thickness, so as to improve the structural strength of the edge of the cover 2 and reduce the risk of screen breakage.

In some embodiments of the present disclosure, as shown in fig. 7, the thickness of the curved edge 22 gradually increases in a direction away from the cover plate body 21. For example, in the specific example shown in fig. 6 to 7, the curved edge 22 on the left side of the cover main body 21 is gradually thickened in the direction from right to left, and the curved edge 22 on the right side of the cover main body 21 is gradually thickened in the direction from left to right. From this, guaranteeing that the thickness of crooked edge 22 is big enough, and under the enough little prerequisite of the thickness of apron main part 21, set up the thickness of crooked edge 22 into the gradual change form, can avoid apron 2 to take place the thickness sudden change in the junction of apron main part 21 and crooked edge 22 effectively to avoid this department because of having the local stress concentration problem that the thickness sudden change causes, avoid apron 2 here to break, promote apron 2's anti falling performance. In addition, the thickness of the bent edge 22 is set to be gradually changed, so that the processing and forming of the cover plate 2 are facilitated, and the processing difficulty is reduced.

In some embodiments of the present disclosure, the maximum thickness of the curved edge 22 is 2.5mm to 0.8mm, that is, the maximum thickness of the curved edge 22 is 0.8mm or more, the maximum thickness of the curved edge 22 is 2.5mm or less, and the thickness of the cover plate body 21 is 0.5mm to 0.65mm, that is, the maximum thickness of the cover plate body 21 is 0.65mm or less, and the minimum thickness of the cover plate body 21 is 0.5mm or more. Thus, the thickness of the bent edge 22 can be ensured to be sufficiently large, the structural strength of the cover plate 2 at the bent position can be improved, and the thickness of the cover plate main body 21 can be ensured to be sufficiently small, so that the light and thin development requirement of the electronic device 100 can be met.

In some embodiments of the present disclosure, as shown in fig. 4, a dispensing gap S1 is formed between the side frame 11 and the curved edge 22, and the curved edge 22 is connected to the side frame 11 by dispensing. Therefore, the glue dispensing connection mode is simple, and the problems of dust entering, water entering and the like of the electronic equipment 100 from the space between the side frame 11 and the bent edge 22 can be avoided, so that the quality of the electronic equipment 100 is improved.
