In some embodiments, the width L1 of the step 192a may range from a value greater than 0.3mm, less than 0.5mm, i.e., 0.3mm < L1<0.5mm, and further, 0.4mm < L1<0.45 mm. Note that the width L1 of the step 192a is the vertical distance between the first face 1921a and the second face 1922a, or the width L3 of the step 192a is the width of the step face 1922 a.

In some embodiments, the width L2 of the inclined surface 1923a may range from greater than 0.2mm to less than 0.3mm, i.e., 0.2mm < L2<0.3mm, and further, 0.2mm < L2<0.25 mm. The width of the inclined surface 1923a is a vertical distance from the stepped surface 1922a to the second surface 1924 a.

As can be seen from the above, in the embodiment of the present application, the sinking platform 191a and the step 192a are formed on the first surface 199a, and the step 192a protects the surface of the sinking platform 191a, so as to reduce the scratch and damage caused by the direct contact between the surface of the sinking platform 191a and an external object. In practical applications, since the height H1 of the step 192a is high, when the step 192a is made of an aluminum alloy material, the step is easily deformed by an applied force, and in order to reduce the deformation of the step 192a by the applied force, in some embodiments, the width L1 of the step 192a may be increased, but increasing the width L1 of the step 192a increases the material, increases the cost, and increases the overall volume of the camera bezel 19 a. In some embodiments, the height H1 of the step 192a can be reduced, and the width L1 of the step 192a can be reduced, so that not only the surface of the sinking platform 191a can be protected, but also the height of the step 192a can be reduced, and the possibility that the step 192a is deformed due to stress can be reduced. The following description will be made in detail by taking the example of lowering the height of the step 192 a.

In some embodiments, the through-hole 193a penetrates the stage 191a in the thickness direction of the stage 191 a.

In some embodiments, please refer to fig. 12 to 14, fig. 12 is another schematic structural diagram of a camera bezel provided in the embodiment of the present application, fig. 13 is another schematic structural diagram of a camera bezel provided in the embodiment of the present application, and fig. 14 is a cross-sectional view of fig. 12 in a B-B direction. The camera bezel 19b may include a through hole 193b, and the through hole 193b may include a first through hole 1931b and a second through hole 1932b, and specifically, the through hole 193b may refer to the through hole 193, which is not described herein.

The camera bezel 19b may further include a placement slot 194b, and the placement slot 194b may refer to the placement slot 194, which is not described in detail herein.

In some embodiments, fig. 12-14 differ from fig. 7 in that: the camera bezel 19b shown in fig. 12 to 14 may further include a counter 191b and a step 192 b.

Wherein, the sunken platform 191b is formed on the first surface 199b of the camera head decorative ring 19 b.

The step 192b is formed on the periphery of the sinking platform 191b, the step 192b extends outwards around the periphery of the sinking platform 191b, and specifically, the step 192b extends around the periphery of the sinking platform 191b from the second surface 196b to the first surface 199 b. In some embodiments, the step 192b has a first face 1921b, a step face 1922b, an inclined face 1923b, and a second face 1924b connected in series.

Wherein the first face 1921b is located at the inner circle of the step 192b, that is, the first face 1921b is located at the inner surface of the step 192b, and the first face 1921b is close to the sinking platform 191 b.

Where step face 1922b is located at a free end of step 192b or at a top end of step 192 b. The stepped surface 1922b may be perpendicular to the first surface 1921b or perpendicular to the second surface 1924b, and the stepped surface 1922b may be parallel to the surface of the sink 191 b.

The inclined surface 1923b is inclined with respect to the step surface 1922b and the second surface 1924b, the inclined surface 1923b may form an angle greater than 0 degree and smaller than 90 degrees with respect to the step surface 1922b, the inclined surface 1923b may form an angle greater than 0 degree and smaller than 90 degrees with respect to the second surface 1924b, and the inclined surface 1923b may form an angle greater than 0 degree and smaller than 90 degrees with respect to the surface of the sinking platform 191 b. The inclined surface 1923b may be configured as a high bright edge, and reference may be made to the inclined surface 1923, which will not be described herein. In some embodiments, the inclined surface 1923b extends from the step 192b toward the second surface 196b, and a side of the inclined surface 1923b connected to the second face 1924b is located between the depressed portion 191b and the second surface 196 b.

Wherein second face 1924b is positioned outboard of step 192b, i.e., second face 1924b is positioned outboard of step 192 b. The second face 1924b can be opposite the first face 1921b, and the second face 1924b can be parallel to the first face 1921 b. The second face 1924b is distal to the sink 191 b.

The step of the embodiment of the present application may include only the first surface, the step surface, and the second surface connected in this order, without including the inclined surface 1923 b.

In some embodiments, fig. 12-14 differ from fig. 8-11 in that: the height of step 192b is less than the height of step 192 a. Specifically, please refer to fig. 15, in which fig. 15 is an enlarged view of D in fig. 14. The height H2 of the step 192a may range from greater than 0.03mm to less than 0.1mm, i.e., 0.03mm < H2<0.1mm, and further, 0.06mm < H2<0.08 mm. Therefore, when the camera decorative ring 19b is made of an aluminum alloy material, the step height is small, an external object is not easy to directly touch the outer surface of the step, and even if the external object touches the step, the deformation is not easy to generate due to the low height of the step. Therefore, the steps of the embodiment of the application can protect the sunk platform of the camera decorating ring 19b, are not easy to damage, and can improve the overall strength of the camera decorating ring under the condition of not increasing the volume and the material.

In some embodiments, the width L3 of the step 192b may range from greater than 0.15mm to less than 0.3mm, i.e., 0.15mm < L3<0.3mm, and further, 0.2mm < L3<0.25 mm. Note that the width L3 of the step 192b is the vertical distance between the first face 1921b and the second face 1922b, or the width L3 of the step 192b is the width of the step face 1922 b.

In some embodiments, the width L4 of the inclined surface 1923b may range from greater than 0.15mm to less than 0.2mm, i.e., 0.15mm < L4<0.2mm, and further, 0.16mm < L4<0.18 mm. The width of the inclined surface 1923b is a vertical distance from the stepped surface 1922b to the second surface 1924 b. The width of the inclined surface 1923b may be set to 0.25 mm. The width of the step 192b is smaller, and the width of the step 192b is similar to the width of the inclined surface 1923b, so that when the step surface is scratched, the scratch position of the step surface is basically similar to the color of the inclined surface due to the narrow width of the step, and the step surface is not easily scratched when being observed from the outside.

Therefore, the width of the step 1922b can be reduced, the material can be saved on the basis of keeping the strength of the camera decorating ring 19b and preventing scratches, and the overall size of the camera decorating ring 19b can be reduced.

In some embodiments, the through hole 193b penetrates the stage 191b in the thickness direction of the stage 191 b.
