Optionally, the width of the first striations 100 is 0.015mm, and the distance between two adjacent first striations 100 is 0.005 mm.

Referring to fig. 2, fig. 2 is a schematic diagram illustrating an assembly relationship of a battery cover, a middle frame and a front cover according to an embodiment of the present disclosure. In the specific use process of the battery cover 10, the battery cover 10 needs to be matched with the middle frame 20 and the front cover 30 of the electronic device 1, the battery cover 10, the middle frame 20 and the front cover 30 are sequentially stacked, and the battery cover 10 is matched with the middle frame 20 and the front cover 30 of the electronic device 1 to form a receiving space for receiving electronic components of the electronic device 1, such as a circuit board, a battery, a camera module, a fingerprint module and the like. The external surface 10a of the battery cover 10 is a surface of the battery cover 10 away from the front cover 30, and specifically, refers to a surface of the electronic device 1 facing away from the front cover 30. The external surface 10a of the battery cover 10 may be a flat surface or a curved surface.

Optionally, the area of the first region a1 is smaller than the area of the appearance surface of the battery cover 10.

Optionally, at least some of the first stripes 100 in the first area a1 are parallel to each other.

The first stripes 100 parallel to each other reflect light, so that the brightness degrees presented by the first area a1 are consistent, the brightness degrees presented by each part of the first area a1 in the same direction can be the same through the mutual compensation between the first stripes 100 parallel to each other and the first stripes 100 not parallel to each other, the brightness degrees presented by the first area a1 in different directions are different, the brightness degrees presented by different directions of the battery cover 10 are different, the overall visual effect of the battery cover 10 is improved, and the visual effect is more coordinated.

Further, please refer to fig. 3 and fig. 4, in which fig. 3 is a schematic layout diagram of a first stripe according to an embodiment of the present application. Fig. 4 is a schematic arrangement of horizontal axes in the first embodiment of the present application. In one embodiment, all the first stripes 100 are parallel to each other, and an angle formed between the first stripes 100 and a horizontal axis 200 is an acute angle α, wherein the horizontal axis 200 extends along a predetermined direction, when the first stripes 100 are parallel to the horizontal axis 200, the first stripes 100 reflect incident light to the greatest extent, and when the first stripes 100 are perpendicular to the horizontal axis 200, the first stripes 100 reflect incident light to the least extent.

Specifically, the battery cover 10 includes a long side 100a and a short side 100b, the short side 100b includes a first portion 100b1, a middle portion 100b2 and a second portion 100b3 connected in sequence, the first portion 100b1 and the second portion 100b3 are curved sections, the middle portion 100b2 is a straight section, and the straight section 100b2 is parallel to the horizontal axis 200. The smaller the included angle between the first stripe 100 on the battery cover 10 and the horizontal axis 200 is, the greater the reflection degree of the first stripe 100 to the incident light is, the brighter the light reflected by the first stripe 100 is, and the lighter the color is visually perceived; the greater the angle between the first stripe 100 and the horizontal axis 200 on the battery cover 10 is, the smaller the degree of reflection of the incident light by the first stripe 100 is, the darker the light reflected by the first stripe 100 is, and the darker the color is visually perceived. In mathematics, the minimum positive angle formed by the intersection of two straight lines (or vectors) is called the included angle of the two straight lines (or vectors), and the included angle ranges from [0, pi/2 ]. By adjusting the change of the angle formed by the first stripe 100 and the horizontal shaft 200, the brightness of the battery cover 10 can be adjusted, which is helpful for improving the overall visual effect of the battery cover 10 and making the visual effect more coordinated.

Further, referring to fig. 5, fig. 5 is a schematic layout view of another first stripe in the first embodiment of the present application. In another embodiment, all the first striations 100 are parallel to each other, and the angle formed between the first striations 100 and the horizontal axis 200 is an obtuse angle β. Mathematically, two intersecting straight lines are rotated from one of the straight lines by an angle parallel to or coincident with the other straight line, the angle of rotation being the angle formed by the two straight lines, in the range of [0, π ]. The horizontal axis 200 extends along a preset direction, when the first stripe 100 is parallel to the horizontal axis 200, the first stripe 100 reflects incident light to the maximum, and when the first stripe 100 is perpendicular to the horizontal axis 200, the first stripe 100 reflects incident light to the minimum.

Specifically, the battery cover 10 includes a long side 100a and a short side 100b, the short side 100b includes a first portion 100b1, a middle portion 100b2 and a second portion 100b3 connected in sequence, the first portion 100b1 and the second portion 100b3 are curved sections, the middle portion 100b2 is a straight section, and the straight section 100b2 is parallel to the horizontal axis 200. The smaller the included angle between the first stripe 100 on the battery cover 10 and the horizontal axis 200 is, the greater the reflection degree of the first stripe 100 to the incident light is, the brighter the light reflected by the first stripe 100 is, and the lighter the color is visually perceived; the greater the angle between the first stripe 100 and the horizontal axis 200 on the battery cover 10 is, the smaller the degree of reflection of the incident light by the first stripe 100 is, the darker the light reflected by the first stripe 100 is, and the darker the color is visually perceived. By adjusting the change of the angle formed by the first stripe 100 and the horizontal shaft 200, the brightness of the battery cover 10 can be adjusted, which is helpful for improving the overall visual effect of the battery cover 10 and making the visual effect more coordinated.

Further, please refer to fig. 6, in which fig. 6 is a schematic layout diagram of a first stripe according to another embodiment of the present application. In yet another embodiment, the first stripe 100 includes a first sub-stripe 110 and a second sub-stripe 120. All of the first sub-stripes 110 are parallel to each other, and the angle formed between the first sub-stripes 110 and the horizontal axis 200 is an acute angle α 1, all of the second sub-stripes 120 are parallel to each other, and the angle formed between the second sub-stripes 120 and the horizontal axis 200 is an obtuse angle β 1. The horizontal axis 200 extends along a preset direction, when the first stripe 100 is parallel to the horizontal axis 200, the first stripe 100 reflects incident light to the maximum, and when the first stripe 100 is perpendicular to the horizontal axis 200, the first stripe 100 reflects incident light to the minimum.

Specifically, since the angle formed between the first sub-stripe 110 and the horizontal axis 200 is an acute angle α 1, and the angle formed between the second sub-stripe 120 and the horizontal axis 200 is an obtuse angle β 1, all of the first sub-stripes 110 are arranged in parallel at intervals, and all of the second sub-stripes 120 are arranged in parallel at intervals. Therefore, all the first sub-stripes 110 reflect the same degree of light incident in the same direction, and the first sub-stripes 110 reflect light incident in different directions to different degrees, so that the brightness of the first area a1 in the same direction is the same, and the brightness of the first area a1 in different directions is different. Moreover, all the second sub-stripes 120 reflect the same incident light in the same direction, and the second sub-stripes 120 reflect the incident light in different directions to different degrees, so that the brightness of each part of the first area a1 in the same direction is the same, and the brightness of each part of the first area a1 in different directions is different. The first sub-stripe 110 and the second sub-stripe 120 compensate each other, so that the brightness of the first area a1 of the cell cover 10 as a whole can be adjusted. Specifically, the brightness of the battery cover 10 can be adjusted by different arrangement modes of the first sub-stripe 110 and the second sub-stripe 120, which is helpful for improving the overall visual effect of the battery cover 10 and making the visual effect more coordinated.

Referring to fig. 7 and 8 together, fig. 7 is a schematic structural diagram of a battery cover according to a second embodiment of the present disclosure, and fig. 8 is a schematic structural diagram of another battery cover according to the second embodiment of the present disclosure. The second embodiment has substantially the same structure as the first embodiment, except that in the second embodiment, the first region a1 includes a first sub-region a11 and a second sub-region a 22. The first stripe 100 includes a first sub-stripe 110 and a second sub-stripe 120. The first sub-stripe 110 is disposed in the first sub-region a11, and the second sub-stripe 120 is disposed in the second sub-region a 22. The first sub-stripe 110 is not parallel to the second sub-stripe 120, and an angle between the first sub-stripe 110 and the horizontal axis 200 is equal to an angle between the second sub-stripe 120 and the horizontal axis 200. Wherein the horizontal axis 200 extends along a predetermined direction, wherein when the first sub-stripe 110 is parallel to the horizontal axis 200, the first sub-stripe 110 reflects incident light to the greatest extent, and when the first sub-stripe 110 is perpendicular to the horizontal axis 200, the first sub-stripe 110 reflects incident light to the least extent.

Specifically, referring to fig. 7, an angle formed between the first sub-stripe 110 and the horizontal axis is an acute angle α 2, an angle formed between the second sub-stripe 120 and the horizontal axis is an acute angle α 3, and α 2 is α 3, according to the reflection principle, the same type of stripes having the same included angle with the horizontal axis have the same reflection degree on the light, so that the first sub-stripe 110 in the first sub-area a11 and the second sub-stripe 120 in the second sub-area a22 have the same reflection degree on the light, and thus, the brightness of the battery cover 10 can be adjusted by adjusting the angle formed between the first sub-stripe 110 and the second sub-stripe 120, which is beneficial to improving the overall visual effect of the battery cover 10, and makes the visual effect more coordinated.

Also, referring to fig. 8, an angle formed between the first sub-stripe 110 and the horizontal axis is an obtuse angle β 2, an angle formed between the second sub-stripe 120 and the horizontal axis is an obtuse angle β 3, and β 2 ═ β 3. According to the reflection principle, the stripes of the same type having the same included angle with the horizontal axis have the same reflection degree to the light, so that the first sub-stripe 110 in the first sub-region a11 and the second sub-stripe 120 in the second sub-region a22 have the same reflection degree to the light, and thus, the brightness degree of the battery cover 10 can be adjusted by adjusting the angle formed between the first sub-stripe 110 and the second sub-stripe 120, which is helpful for improving the overall visual effect of the battery cover 10, and the visual effect is more coordinated.

Referring to fig. 9, fig. 9 is a schematic structural diagram of a battery cover according to a third embodiment of the present application. The third embodiment is substantially the same as the first embodiment, except that in the third embodiment, the first region a1 includes a first sub-region a11 and a second sub-region a22, the first stripe 100 includes a first sub-stripe 110 and a second sub-stripe 120, the first sub-stripe 110 is disposed in the first sub-region a11, the second sub-stripe 120 is disposed in the second sub-region a22, and the densities of the first sub-stripe 110 and the second sub-stripe 120 are different.

Specifically, the brightness of the stripes is related to the size of the included angle between the stripes and the horizontal axis, and also related to the arrangement density between the stripes. In this embodiment, by defining the density of the first sub-stripe 110 and the second sub-stripe 120 to be different, the brightness of the first sub-region a11 and the second sub-region a22 can be adjusted, and the overall brightness of the battery cover 10 can be adjusted. Further, as the included angle between the straight stripe on the battery cover 10 and the horizontal axis 200 is smaller, the light reflected by the straight stripe is brighter, and the color is visually lighter; the greater the angle between the straight stripe on the cell cover 10 and the horizontal axis 200, the darker the light reflected by the straight stripe and the darker the color visually perceived. Therefore, when the included angle between the first sub-stripe 110 and the horizontal axis 200 is smaller, the arrangement density of the first sub-stripe 110 can be controlled to be relatively sparse; when the included angle between the second sub-stripe 120 and the horizontal axis 200 is larger, the arrangement density of the second sub-stripe 120 can be controlled to be relatively dense; therefore, when the battery cover 10 is observed from the same direction, the overall brightness is kept consistent, and when the battery cover is observed from different directions, different brightness degrees are displayed, so that the overall brightness degree of the battery cover 10 is adjustable, the visual effect is improved, and the visual effect is more coordinated.

Optionally, referring to fig. 10, fig. 10 is a schematic cross-sectional structure diagram of a first sub-stripe and a second sub-stripe in an embodiment of the present application. In one embodiment, the cross-sectional shape of the first sub-stripe 110 along the extending direction of the first sub-stripe 110 is smoothly transited, and the cross-sectional shape of the second sub-stripe 120 along the extending direction of the second sub-stripe 120 is not smoothly transited.

Specifically, smooth transition means that the curve equation can be derived and the curvature is continuously changed. The non-smooth transition means that the curve equation can not be derived and the curvature changes discontinuously. The curve a in fig. 10 is a smooth transition, and B and C are non-smooth transitions, when the cross-sectional shape of the first sub-stripe 110 along the extending direction of the first sub-stripe 110 is smoothly transitioned, i.e. the cross-sectional shape of the first sub-stripe 110 along the extending direction of the first sub-stripe 110 is as shown by the curve a, the brighter the light reflected by the first sub-stripe 110, the lighter the visually presented color. When the cross-sectional shape of the second sub-stripe 120 along the extending direction of the second sub-stripe 120 is not smoothly transited, i.e. the cross-sectional shape of the second sub-stripe 120 along the extending direction of the second sub-stripe 120 is shown by the B curve or the C curve, the darker the light reflected by the second sub-stripe 120, the darker the visually appearing color. Therefore, the cross-sectional shapes of the extending directions of the first sub-stripe 110 and the second sub-stripe 120 can be controlled, so that the brightness of the whole battery cover 10 is kept consistent when the battery cover is observed from the same direction, and different brightness degrees are shown when the battery cover is observed from different directions, so that the brightness degree of the whole battery cover 10 can be adjusted, the visual effect can be improved, and the visual effect can be more coordinated.

Referring to fig. 11, fig. 11 is a schematic structural diagram of a battery cover according to a fourth embodiment of the present application. The fourth embodiment is substantially the same as the first embodiment, except that in the fourth embodiment, the battery cover 10 further includes a second region a2, a plurality of second stripes 300 are arranged in the second region a2 at intervals, and the first stripes 100 and the second stripes 300 reflect incident light rays in the same direction to different degrees, so that the first region a1 and the second region a2 in the same direction have the same brightness and darkness, and the first region a1 and the second region a2 in different directions have different brightness and darkness.

Optionally, in an embodiment, the first region a1 and the second region a2 share at least one edge. That is, the first region a1 is disposed adjacent to and in contact with the second region a 2. Because the first stripe 100 and the second stripe 300 have different reflection degrees for incident light rays in the same direction, the brightness degrees of the first area a1 and the second area a2 in the same direction are the same, and the brightness degrees of the first area a1 and the second area a2 in different directions are different by adjusting the arrangement of the first stripe 100 and the second stripe 300, so that the brightness degree of the whole battery cover 10 is adjustable, which is helpful for improving the visual effect and making the visual effect more coordinated.

Optionally, please refer to fig. 12, where fig. 12 is a schematic structural diagram of another battery cover according to the fourth embodiment of the present application. In another embodiment, the first region a1 is disposed in non-contact with the second region a 2. I.e. there is no intersection between the first area a1 and the second area a2, there is no common area. Because the first stripe 100 and the second stripe 300 have different reflection degrees for incident light rays in the same direction, the brightness degrees of the first area a1 and the second area a2 in the same direction are the same, and the brightness degrees of the first area a1 and the second area a2 in different directions are different by adjusting the arrangement of the first stripe 100 and the second stripe 300, so that the brightness degree of the whole battery cover 10 is adjustable, which is helpful for improving the visual effect and making the visual effect more coordinated.

Optionally, please refer to fig. 13, and fig. 13 is a schematic structural diagram of another battery cover according to the fourth embodiment of the present application. In another embodiment, the arrangement density of the first stripes 100 is equal to the arrangement density of the second stripes 300, and the included angle between the first stripes 100 and the horizontal axis 200 is not equal to the included angle between the second stripes 300 and the horizontal axis 200.

Specifically, the brightness of the stripes is related to the arrangement density of the stripes, and also related to the included angle between the stripes and the horizontal axis. In this embodiment, by limiting the arrangement density of the first stripes 100 to be equal to the arrangement density of the second stripes 300, and the included angle between the first stripes 100 and the horizontal axis 200 is not equal to the included angle between the second stripes 300 and the horizontal axis 200, the brightness of the first area a1 and the brightness of the second area a2 can be adjusted, and thus the overall brightness of the battery cover 10 can be adjusted. Further, as the included angle between the straight stripe on the battery cover 10 and the horizontal axis 200 is smaller, the light reflected by the straight stripe is brighter, and the color presented visually is lighter; the larger the angle between the straight stripe on the cell cover 10 and the horizontal axis 200, the darker the light reflected by the straight stripe and the darker the visually appearing color. Therefore, when the arrangement density of the first stripes 100 is equal to the arrangement density of the second stripes 300, the size of the included angle between the first stripes 100 and the included angle between the second stripes 300 and the horizontal shaft 200 can be controlled, so that the battery cover 10 can be observed from the same direction, the overall brightness is different, the battery cover 10 can show the same brightness when observed from different directions, the overall brightness of the battery cover 10 can be adjusted, the improvement of the visual effect is facilitated, and the visual effect is more coordinated.

Referring to fig. 14, fig. 14 is a schematic structural diagram of a battery cover according to a fifth embodiment of the present application. The fifth embodiment is substantially the same as the fourth embodiment, except that in the fifth embodiment, the battery cover 10 further includes a third area A3, the third area A3 is provided with a plurality of third stripes 400, the first stripe 100 and the second stripe 300 reflect light rays incident in the same direction to different degrees, and the second stripe 300 and the third stripe 400 reflect light rays incident in the same direction to the same degree, so that the first area a1 and the second area a2 in the same direction exhibit different degrees of brightness, and the second area a2 and the third area A3 exhibit the same degrees of brightness.

In one embodiment, the second area a2 and the third area A3 are symmetrical with respect to the first area a1, the included angles between the second stripe 300 in the second area a2 and the third stripe 400 in the third area A3 and the horizontal axis 200 are consistent, the first stripe 100 and the second stripe 300 reflect incident light rays in the same direction to different degrees, and the second stripe 300 and the third stripe 400 reflect incident light rays in the same direction to the same degree, so that the brightness degrees presented by the first area a1 and the second area a2 in the same direction are different, and the brightness degrees presented by the second area a2 and the third area A3 are the same, thereby achieving the adjustable brightness degree presented by the whole battery cover 10, which is helpful for improving the visual effect and making the visual effect more harmonious.

Referring to fig. 15, fig. 15 is a schematic structural diagram of a battery cover according to a preferred embodiment of the present application. It should be noted that the cell cover 10 is not limited to include only the first region a1, the second region a2 and the third region A3, but may include more regions, where the m-th region is defined as Am and the n-th region is defined as An, where m and n are positive integers.

The predetermined pattern may be, but is not limited to, a diamond pattern, a jewelry pattern, etc. In particular, it can be realized that the brightness of each region of the battery cover 10 is consistent in the same orientation, so that the battery cover 10 as a whole presents a single pattern, for example, the battery cover 10 as a whole presents a light blue color. The brightness of each region of the battery cover 10 can also be adjusted so that the battery cover 10 can display a three-dimensional predetermined pattern, such as a diamond pattern.
