Referring to fig. 1 and fig. 2, the present application provides a mobile terminal 100, where the mobile terminal 100 may be a mobile phone or a tablet computer. The mobile terminal 100 of the present embodiment is described taking a mobile phone as an example, and the mobile terminal 100 includes a housing 10 and a display 20 provided on the housing 10.
The housing 10 can be used for mounting the display 20 and receiving electronic components of the mobile terminal 100, and the housing 10 has various structural forms. The housing 10 includes a front case, a rear case 11, and a middle frame 12. The middle frame 12 is connected between the front shell and the rear shell 11, the display screen 20 is approximately covered on one side of the front shell, and the rear shell 11 is arranged on one side of the front shell, which is back to the display screen 20, and is connected with the middle frame 12. As shown in fig. 3 and 4, the housing 10 may be omitted from the front shell, that is, the housing 10 includes a rear shell 11 and a middle frame 12, and after the display panel 20 is mounted on the housing 10, the edge of the display panel 20 is substantially integrally joined to the middle frame 12.
The middle frame 12 is a substantially rectangular frame, and constitutes a frame of the mobile terminal 100. For convenience of understanding, an X-Y-Z rectangular coordinate system is established in the measurement directions of the length, width and thickness of the mobile terminal 100, and a frame of the mobile terminal 100 refers to a side portion of the mobile terminal 100 in the thickness direction (the Z-axis direction shown in fig. 1), which forms an external appearance of the mobile terminal 100 together with a rear surface 101 (e.g., an outer surface of the rear case 11) and a front surface 102 (e.g., an outer surface of the display 20) of the mobile terminal 100. The bezel of the mobile terminal 100 may be integral with the structural member constituting the front surface 102 or the structural member constituting the rear surface 101. For example, as shown in fig. 3, the middle frame 12 is integrally formed with the rear case 11. Alternatively, in some embodiments, part or all of the outer surface of the display screen 20 is formed on a glass cover plate that is integrally formed with the bezel 12.
In other embodiments, the middle frame 12 may form a frame portion of the mobile terminal 100, and the rear housing 11 is connected to the middle frame 12 by means of a snap, or by gluing or injection molding, which will not be described herein.
As shown in fig. 5, the middle frame 12 includes two side end surfaces 122 and a first end surface 121 connected between the two side end surfaces 122. When the bezel 12 is attached to the mobile terminal 100, the side end surface 122 and the first end surface 121 constitute different side surfaces of the mobile terminal 100. Taking a mobile terminal 100 in a rectangular block shape as an example, the mobile terminal 100 has opposite long sides and short sides. The size of the middle frame 12 is adapted to the installation requirement, the first end surface 121 may be located on one side of the long side of the mobile terminal 100, and the first end surface 121 may also be located on one side of the short side of the mobile terminal 100, as the top end surface or the bottom end surface of the mobile terminal 100.
The length of the first end surface 121 and the length of the side end surface 122 may be configured as required. For example, fig. 5 shows the middle frame 12 in which the first end surface 121 extends longer in the circumferential direction of the middle frame 12 than the side end surface 122. As another example, in the middle frame 12 shown in fig. 11, the length W of the first end surface 121 in the circumferential direction of the middle frame 12 is shorter than the length L of the side end surface 122 in the circumferential direction of the middle frame 12. The length of the two side end surfaces 122 may be equal, or one side end surface 122 may be longer and the other side end surface 122 may be shorter, which is not limited herein.
As shown in fig. 5 and 6, the first end surface 121 includes a first surface 121a and a second surface 121b that are adjacent to each other. For convenience of description of the structure of the middle frame 12, the middle frame 12 is hereinafter referred to as being mounted to the mobile terminal 100. When the middle frame 12 is mounted to the mobile terminal 100, the first surface 121a and the second surface 121b are arranged in a thickness direction of the mobile terminal 100 (i.e., a Z-axis direction shown in fig. 1). The second surface 121b is inclined with respect to the first surface 121a toward the middle of the middle frame 12. The first edge 1211 is formed at the position where the first surface 121a is adjacent to the second surface 121b, and the first edge 1211 extends along the peripheral side of the middle frame 12 and is connected to the lateral end surface 122. The second surface 121b is concave, and a contour line of the second surface 121b formed on a cross section S in the thickness direction of the mobile terminal 100 is an arc line.
In this embodiment, since the second surface 121b is concave and inclined toward the middle of the middle frame 12 relative to the first surface 121a, the second surface 121b will generate different light effects from the first surface 121a in visual sense, and the overall width of the middle frame 12 will be relatively narrow in visual sense. Therefore, with this structural arrangement, the light effect of the second surface 121b weakens the overlapping effect on the width of the first surface 121a, so that the middle frame 12 appears thinner, thereby making the mobile terminal 100 using the middle frame 12 appear thinner as a whole.
The first surface 121a may be a flat surface or a curved surface 202. For example, as shown in fig. 6, in some embodiments, the first surface 121a is convex so that the first surface 121a is disposed relatively concave to the second surface 121b, the glossy effect of the first surface 121a will be more pronounced so that visually, the first surface 121a forms relatively bright areas and the second surface 121b forms relatively dark areas, when the first end surface 121 is viewed from the middle frame 12 as a whole, the bright areas formed by the first surface 121a will dominate the visual width of the first end surface 121, while the relatively darker second surface 121b has a superimposed effect on the visual width, so that the first end surface 121 appears narrower, and thus a thinner visual effect is obtained.
The width of the side end surface 122 is less than or equal to the width of the first surface 121a in the thickness direction of the mobile terminal 100. The side end surface 122 is made narrower at the side, which is consistent with the narrow frame effect obtained by the first end surface 121. It should be noted that, in this configuration, the narrow frame effect obtained by making the width of the side end surface 122 narrower than that of the first end surface 121 is consistent.
In other embodiments, the side end surface 122 may also be configured as the first end surface 121, so that the visual width is narrow. For example, the actual width of the side end surface 122 is equivalent to the actual width of the first end surface 121, two surfaces respectively engaged with the first surface 121a and the second surface 121b are provided on the side end surface 122, and with the structural arrangement form of the first end surface 121, the two surfaces on the side end surface 122 exhibit different visual effects, so that the visual width of the side end surface 122 is narrower than the actual width. For easy understanding, the joining effect of the side end surface 122 and the first end surface 121 can be regarded as that the plurality of first end surfaces 121 are smoothly joined in the circumferential direction of the middle frame 12, that is, a narrow frame effect narrower than the actual width can be obtained visually when viewed facing any one of the first end surfaces 121.
The second surface 121b has a first end 1203 and a second end 1204 along the first edge 1211, and the first end 1203 and the second end 1204 are gradually narrowed and respectively joined to the two side end surfaces 122. With this configuration, the second surface 121b is smoothly joined to the side end surface 122, and a preferable overall visual effect is obtained.
Further, the second surface 121b is generally crescent-shaped when viewed from the side where the second surface 121b is located. Specifically, the edge of the second surface 121b includes, in addition to the first edge 1211, an edge line located on a side 1213 away from the first surface 121a, and two ends of the edge line and two ends of the first edge 1211 are respectively in arc transition and converge together, so that the second surface 121b is crescent-shaped as a whole. With this configuration, on the one hand, the second surface 121b can be smoothly joined to the side end surface 122, and on the other hand, a curved edge visual effect can be obtained, and the grip feeling is good.
In some embodiments, first end face 121 and side end face 122 may be joined together in a smooth transition, whether or not side end face 122 takes a narrow bezel visual design form similar to first end face 121. For example, the first surface 121a is smoothly joined to the side end surface 122, and the second surface 121b is also joined to the side end surface 122 in a smoothly joined manner. Thus, from the overall visual effect, the first end surface 121 presents a narrow bezel effect without affecting the visual coordination with the side end surface 122. In this embodiment, the width of the first end surface 121 may be equal to the width of the side end surface 122.
As further shown in fig. 5 and 8, the first edge 1211 includes a straight section 1201 and an arc section 1202, and the straight section 1201 smoothly transitions to the lateral end surface 122 through the arc section 1202. First surface 121a engages lateral surface 122 in a smooth transition, while second surface 121b converges and engages lateral surface 122 via curved edge portion 1202 of first edge 1211.
In other embodiments, the first surface 121a and the side end surface 122 are not smoothly transited, but form an edge at the junction of the two, and the second surface 121b is joined to the side end surface 122 in a smoothly transited manner, at this time, the structure of the second surface 121b relative to the first surface 121a can still enable the first end surface 121 to obtain the visual effect of a narrow frame.
As shown in fig. 6 and 7, in some embodiments, the middle frame 12 includes an inner wall 1214 disposed opposite to the first surface 121a and the second surface 121b, the inner wall 1214 defines a recessed area, and when the middle frame 12 is mounted on the mobile terminal 100, a part of the camera module 30 of the mobile terminal 100 is accommodated in the recessed area. With such a structure, on one hand, the middle frame 12 can be fully utilized to provide a certain installation space for the camera module 30, and the structure of the second surface 121b relative to the first surface 121a reduces the overall visual thickness of the middle frame 12, so that the camera module 30 is not visually increased in thickness of the mobile terminal 100. On the other hand, referring to fig. 10, since a part of the structure of the camera module 30 can be fitted into the recessed area of the middle frame 12, the optical axis 30b of the lens 32 of the camera module 30 can be as close as possible to the frame side of the middle frame 12, that is, the distance d between the border of the optical axis 30b and the side 1213 of the second surface 121b farther from the first surface 121a and the optical axis 30b can be smaller, so as to reduce the width of the black border and improve the screen occupation ratio.
In some embodiments, as shown in fig. 1, 7 and 10, when the camera module 30 is mounted on the mobile terminal 100, the light incident surface 30a of the camera module 30 is exposed to the side of the display screen 20, so as to meet the shooting requirement of the camera module 30. The camera module 30 includes a lens holder 31, a lens 32 and a photosensitive element 33, wherein the lens 32 is mounted on the lens holder 31, and can irradiate the light entering the lens 32 to the photosensitive area of the photosensitive element 33 after optical processing, so as to meet the requirement of shooting and imaging.
Further, a part of the structure of the camera module 30 is accommodated in the recessed area, the lens holder 31 and a part of the structure of the photosensitive element 33 are accommodated in the recessed area, or a part of the structure of the lens 32, a part of the structure of the lens holder 31 and a part of the structure of the photosensitive element 33 are accommodated in the recessed area, and only external light beams need to be irradiated from the light incident surface 30a of the camera module 30 to the photosensitive area of the photosensitive element 33 through the lens 32, so that the shooting requirement is met.
Referring to fig. 8, the first end surface 121 includes a third surface 121c, the third surface 121c is adjacent to the first surface 121a, the first surface 121a is located between the second surface 121b and the third surface 121c, and the third surface 121c is inclined toward the middle of the middle frame 12 relative to the first surface 121 a. With this arrangement, the first surface 121a has different gloss from the second and third surfaces 121b and 121c, thereby exhibiting a narrow bezel effect while satisfying the requirement of the actual width of the bezel 12.
As shown in fig. 9, the third surface 121c may be a concave surface, and a contour line formed by the third surface 121c in the cross section S is an arc line. Not only can obtain better cambered surface aesthetic feeling, but also can adapt to the requirements of darker gloss compared with the first surface 121a, thereby enhancing the narrow frame visual effect of the middle frame 12.
The middle frame 12 includes an inner wall 1214 opposite to the first surface 121a, the second surface 121b, and the third surface 121c, the inner wall 1214 defines a recessed area, and when the middle frame 12 is mounted on the mobile terminal 100, a part of the camera module 30 of the mobile terminal 100 is accommodated in the recessed area.
As shown in fig. 8 and 9, the abutment of the first surface 121a and the third surface 121c forms a second edge 1212, and the second edge 1212 extends along the peripheral side of the middle frame 12 and is connected to the lateral end surface 122.
The lateral end surface 122 has a first side 1221 and a second side 1222, a first edge 1211 joined to the first side 1221, and a second edge 1212 joined to the second side 1222.
It will be appreciated that in some embodiments, the middle frame 12 may be an open structure as shown in fig. 5, 8 and 11, that is, when the middle frame 12 includes two side end surfaces 122 and a first end surface 121, the two side end surfaces 122 and the first end surface 121 are integrally shaped as "Contraband". In other embodiments, the middle frame 12 may also be a closed frame structure as shown in fig. 12A. For example, the middle frame 12 includes a second end face 123 opposite to the first end face 121, and the second end face 123 is connected between the two side end faces 122. Thus, the first end surface 121, the second end surface 123 and the two side end surfaces 122 form a closed middle frame 12 structure. As shown in fig. 12A and 12B, when the middle frame 12 is mounted to the mobile terminal 100, the width h2 of the second end face 123 is equal to the width h1 of the side end face 122 in the thickness direction of the mobile terminal 100.
As shown in connection with fig. 13A and 13B, the second end face 123 may take the form of a structure of the first end face 121, i.e., a structure similar to that between the first surface 121a and the second surface 121B. For convenience of description, to avoid confusion with the first surface 121a and the second surface 121b of the first end surface 121, in describing the second end surface 123, the base surface 1231 and the extension surface 1232 are used herein, and in fact, regardless of the orientation of the first end surface 121 and the second end surface 123 in the overall structure of the middle frame 12, the structural form of the second end surface 123 may be the same as that of the first end surface 121, that is, the structural form of the base surface 1231 in this embodiment is similar to that of the first surface 121a of the first end surface 121, and the structural form of the extension surface 1232 is similar to that of the second surface 121b or the third surface 121c of the first end surface 121.
Specifically, the second end face 123 includes a base surface 1231 and an extension surface 1232, the extension surface 1232 is adjacent to the base surface 1231 in the width direction of the base surface 1231, the extension surface 1232 is inclined toward the middle of the middle frame 12 relative to the base surface 1231, and the extension surface 1232 is a concave surface.
The extension surface 1232 is joined smoothly to the side end surface 122.
In the thickness direction of the mobile terminal 100, the base 1231 has two side edges 1231a, 1231b, the side end surface 122 has a first side 1221 and a second side 1222, and the side edge 1231a is joined to the first side 1221 and the side edge 1231b is joined to the second side 1222.
Referring to fig. 1 and 8 again, in the thickness direction of the mobile terminal 100, the first surface 121a has two opposite sides, the first edge 1211 is located on one side of the first surface 121a, the other side of the first surface 121a has a second edge 1212, the first edge 1211 is connected to the first side 1221, and the second edge 1212 is connected to the second side 1222. Therefore, by using the structure, the overall visual effect of the middle frame 12 is not only thin, but also the end surfaces of the middle frame 12 are coordinated, thereby improving the overall beauty of the mobile terminal 100 equipped with the middle frame 12.
It should be noted that, for the mobile terminal 100, the display screen 20 is usually connected to the middle frame 12 in a manner that the display surface faces away from the middle frame 12. In some embodiments, a side 1213 of the second surface 121b that is further from the first edge 1211 is coupled to the display screen 20.
The connection between the second surface 121b and the display screen 20 has various forms, and the display screen 20 may take various forms to be connected to the middle frame 12. For example, as shown in fig. 1 and 5, the portion of the display 20 forming the surface of the mobile terminal 100 includes a plane 201 and a curved surface 202, and the plane 201 is joined to a side 1213 of the second surface 121b farther from the first edge 1211.
