The rear housing 210 further includes a substrate 211 and a decoration layer 213, the substrate 211 is substantially rectangular block-shaped, the substrate 211 includes a front surface 212 and a rear surface 214 which are oppositely arranged, and the decoration layer 213 is connected to the front surface 212. The substrate 211 may be made of plastic, and the decoration layer 213 may be made of paint or ink. In the embodiment where the substrate 211 is made of plastic, the decoration layer 213 is exposed to allow a user to directly observe the appearance of the decoration layer 213, and the user can directly touch the outer surface of the decoration layer 213. Since the area of the rear case 210 is relatively large, a major portion of the appearance of the mobile terminal 10 may be presented through the decorative layer 213 on the substrate 211. For example, the decorative layer 213 may present a pattern or a gradient effect to enhance the appearance of the mobile terminal 10. In other embodiments, the material of the substrate 211 may be a metal such as an aluminum alloy, a magnesium alloy, or stainless steel, the material of the substrate 211 may also be a ceramic or a glass, and the decoration layer 213 is exposed for exhibiting a desired appearance effect.

The rear housing 210 has a mounting hole 215 penetrating through the substrate 211 and the decoration layer 213, and the mounting hole 215 is surrounded by a hole wall 217. The material of the decoration ring 220 may be stainless steel, aluminum alloy, magnesium alloy, or the like, and the decoration ring 220 is inserted into the mounting hole 215 and connected to the substrate 211. In an embodiment, the decoration ring 220 includes a body 221 and a supporting portion 223 formed integrally, the supporting portion 223 is protruded from the periphery of the body 221, and the supporting portion 223 is located on the side of the rear surface 214 and is fixedly connected to the substrate 211. For example, a double-sided adhesive or a spot adhesive layer may be disposed between the abutting portion 223 and the rear surface 214, so that the decorative ring 220 can form a reliable connection with the rear case 210.

Referring to fig. 4 and 5, the bezel 220 includes an end surface 222 and an outer peripheral surface 224 facing the hole wall 217, wherein the end surface 222 is exposed to the side of the decoration layer 213. The outer peripheral surface 224 of the bezel 220 includes a first region 226 contiguous with the end surface 222, the aperture wall 217 of the mounting aperture 215 includes a second region 218 contiguous with the front surface 212, the second region 218 faces the first region 226, the first region 226 forms a gap with the second region 218, and the width of the gap gradually decreases from the front surface 212 to the rear surface 214, and the minimum width of the gap is between the extension plane of the front surface 212 and the extension plane of the rear surface 214. The above structure can also be expressed as follows: the width of the gap decreases from the decoration layer 213 to the side of the substrate 211 facing away from the decoration layer 213, and the minimum width of the gap is located on the side away from the decoration layer 213 and spaced apart from the decoration layer 213. It is understood that a geometric plane parallel to the thickness direction of the terminal device 100 may be made and used as a reference plane, the decoration ring 220 and the rear case 210 are cut off at the reference plane to obtain a cross section of the decoration ring 220 and the rear case 210 at any position, the intersection line of the front surface 212 and the reference plane includes a line segment that meets the hole wall 217, the intersection line of the rear surface 214 and the reference plane includes a line segment that meets the hole wall 217, and the minimum width of the gap is located between extension lines of the two line segments. With the structure, the minimum distance between the outer circumferential surface 224 of the decoration ring 220 and the hole wall 217 is located below the decoration layer 213, when the mobile terminal 10 falls accidentally, the decoration ring 220 at the minimum width collides with the substrate 211 of the rear shell 210, so that the decoration ring 220 is prevented from directly colliding with the decoration layer 213, and the decoration layer 213 is prevented from cracking due to the fact that the decoration ring 220 collides with the decoration layer 213 when the mobile terminal falls accidentally. It is understood that the feature of gradually decreasing the width of the gap is not necessary, for example, in the thickness direction of the mobile terminal 10, the width of the gap tends to decrease toward the rear surface 214, and the minimum width of the gap is located between the extension plane of the front surface 212 and the extension plane of the rear surface 214, so that the width of the gap at some positions may be decreased and then increased, which is included in the protection scope of the present application.

In one embodiment, the first region 226 forms an obtuse angle with the end surface 222. Specifically, referring to fig. 4, the first region 226 is a curved surface whose generatrix forms an acute angle with the thickness direction of the mobile terminal 10, and the end surface 222 is a flat surface. The angle of the first region 226 to the end face 222 may be obtained by: any generatrix of the first region 226 is taken as a tangent plane of the first region 226, an included angle between the tangent plane and the end face 222 is an obtuse angle, and the end face 222 of the decorative ring 220 and the first region 226 are clamped in the obtuse angle region.
