It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

As shown in fig. 1-3, an embodiment of the present invention discloses a mobile terminal, which may specifically include a display module 100 and a housing 200.

The display module 100 mainly includes a transparent cover plate 110 and a display screen 120, the display screen 120 is fixedly connected to the transparent cover plate 110, and the transparent cover plate 110 covers the display screen 120, so as to protect the display screen 120. In an embodiment, the display screen 120 and the transparent cover plate 110 may be fixed together by bonding.

The case 200 mainly includes a case main body 210, a cover bezel 220, and a bezel-fixing plate 230. The transparent cover plate 110 is disposed on the cover plate decoration ring 220, the cover plate decoration ring 220 is fixedly connected with the decoration ring fixing plate 230, the decoration ring fixing plate 230 is fixedly connected with the shell main body 210, and the decoration ring fixing plate 230 is located on one side of the display screen 120 departing from the transparent cover plate 110. In a specific embodiment, the transparent cover plate 110 and the cover plate decoration ring 220, the cover plate decoration ring 220 and the decoration ring fixing plate 230, and the decoration ring fixing plate 230 and the case main body 210 may be connected by bonding, ultrasonic welding, hot melting, and the like. When assembling the mobile terminal, the transparent cover plate 110 may be first fixedly coupled to the cover plate bezel 220, then the display screen 120 may be fixed to the transparent cover plate 110, then the cover plate bezel 220 and the bezel fixing plate 230 may be fixed together, and finally the bezel fixing plate 230 and the case main body 210 may be fixed together. The cover decoration ring 220 and the decoration ring fixing plate 230 may be made of plastic, metal, glass, or the like.

Among the above-mentioned mobile terminal, apron dress circle 220 can be through dress circle fixed plate 230 and shell main part 210 fixed connection, therefore this dress circle fixed plate 230 can assist the removal of restriction apron dress circle 220 for shell main part 210, make apron dress circle 220 be difficult to appear moving at the equipment mobile terminal (for example reliability test process) and the in-process that uses mobile terminal, also be difficult to collide with display screen 120, consequently, display screen 120 is difficult to break down, mobile terminal's reliability promotes thereupon.

in addition, after the decoration ring fixing plate 230 is added, the problem of glue overflow after the transparent cover plate 110 is bonded with the cover plate decoration ring 220 can be prevented, and therefore the process yield is improved.

Further, in order to better prevent the movement of the cover bezel 220, a coupling recess 231 may be formed on the bezel fixing plate 230, and a coupling protrusion 221 may be formed on the cover bezel 220, and the coupling protrusion 221 cooperates with the coupling recess 231 to limit the movement of the cover bezel 220 in a plane parallel to the display surface of the display screen 120. Here, the coupling recess 231 may be a coupling hole into which the coupling protrusion 221 may be inserted, thereby restricting the movement of the cover bezel 220 in a plane parallel to the display surface of the display screen 120. The connecting convex portion 221 and the connecting concave portion 231 may be provided in one or more number, and in order to improve the limiting effect, the connecting convex portion 221 and the connecting concave portion 231 may be provided in more number, and the connecting convex portions 221 and the connecting concave portions 231 are matched in one-to-one correspondence.

In another alternative embodiment, the coupling recess 231 may also be provided as a coupling groove formed by recessing the side of the bezel-fixing plate 230. That is, the coupling groove may penetrate to the side of the bezel-fixing plate 230, thereby forming a notch structure. So set up the back, the connecting groove is located the edge of decorating circle fixed plate 230 for decorating circle fixed plate 230 and decorating circle 220 for the apron and not protruding basically, thereby minimize and decorate the shared space of circle fixed plate 230, so that arrange other spare parts of mobile terminal.

Further, the coupling protrusion 221 extends in a direction perpendicular to the display surface of the display screen 120, and a side surface of the coupling protrusion 221 is flush with a side surface of the bezel fixing plate 230. This scheme defines a positional relationship between the side of the connection protrusion 221 and the side of the bezel fixing plate 230 so that the connection protrusion 221 does not protrude with respect to the side of the bezel fixing plate 230, thereby reducing a space occupied by the bezel 220 to facilitate arrangement of other parts of the mobile terminal. In addition, the fitting area of the connecting convex part 221 and the connecting groove can be increased as much as possible by the arrangement mode, so that the limiting effect between the connecting convex part 221 and the connecting groove is better.

The connecting groove can be a semicircular groove, an elliptical groove and the like. Alternatively, the inner surface of the coupling groove includes a first plane 231a, a second plane 231b and a third plane 231c which are sequentially coupled, the first plane 231a is opposite to the third plane 231c, and a distance between the first plane 231a and the third plane 231c is gradually increased in a direction perpendicular to the second plane 231b and gradually closer to the second plane 231 b. In other words, the connecting groove may adopt a dovetail groove structure, and when the connecting protrusion 221 is matched with the connecting groove, the movement of the cover bezel 220 in all directions in a plane parallel to the display surface of the display screen 120 can be substantially limited, so that the limiting effect of the connecting groove on the cover bezel 220 is better.

The connection protrusion 221 has a limiting surface engaged with the connection groove, and in order to more reliably limit the movement of the cover trim 220, the limiting surface includes a first surface 221a, a second surface 221b, and a third surface 221c connected in sequence, where the first surface 221a, the second surface 221b, and the third surface 221c are all flat surfaces, the first surface 221a is opposite to the third surface 221c, the second surface 221b is parallel to the second plane 231b, and a distance between the first surface 221a and the third surface 221c gradually increases in a direction perpendicular to the second surface 221b and gradually closer to the second surface 221 b. The connecting convex part 221 is arranged corresponding to the connecting groove, so that the matching area between the connecting convex part 221 and the connecting groove is larger, and the limiting effect is better. Alternatively, the first, second and third planes 231a, 231b and 231c of the coupling groove may be respectively attached to the first, second and third faces 221a, 221b and 221c of the coupling protrusion 221, thereby further improving the spacing effect.

The surface of the side of the coupling protrusion 221 facing away from the transparent cover plate 110 may be recessed, protruded, or both flush with the surface of the side of the bezel-fixing plate 230 facing away from the transparent cover plate 110. When the surface of one side of the connecting convex part 221 departing from the transparent cover plate 110 is recessed relative to the surface of one side of the decorating ring fixing plate 230 departing from the transparent cover plate 110, the matching area between the connecting convex part 221 and the connecting concave part 231 is small, and the limiting effect is poor; when the surface of one side of the connecting protrusion 221 facing away from the transparent cover plate 110 protrudes relative to the surface of one side of the bezel fixture plate 230 facing away from the transparent cover plate 110, the structural stability formed by the cover bezel 220 and the bezel fixture plate 230 is poor; when a side surface of the connecting protrusion 221 facing away from the transparent cover plate 110 is flush with a side surface of the bezel fixing plate 230 facing away from the transparent cover plate 110, a fitting area between the connecting protrusion 221 and the connecting recess 231 is larger, and a structure formed by the bezel 220 and the bezel fixing plate 230 is more stable.

In order to improve the connection strength between the bezel fixing plate 230 and the case main body 210, a side surface of the bezel fixing plate 230 facing away from the transparent cover plate 110 may be bonded to the case main body 210, and specifically, both may be bonded by the second adhesive layer 250. The area of the surface of the bezel-fixing plate 230 on the side facing away from the transparent cover plate 110 is larger, so that it is more convenient to dispose the second adhesive layer 250 on the surface, and the adhesive area between the bezel-fixing plate 230 and the case main body 210 is larger, thereby achieving the aforementioned objects. In addition, the structure can also improve the production efficiency and yield of the dispensing process.

as mentioned above, the transparent cover plate 110 and the cover plate bezel 220 may be bonded together by bonding, and specifically, the transparent cover plate 110 may be bonded to the cover plate bezel 220 by the first adhesive layer 240, and the bonding area of the two will have an influence on the size of the black border of the mobile terminal. In order to reduce the size of the black edge of the mobile terminal, a mounting cantilever 222 is disposed on a side of the cover bezel 220 facing the display screen 120, the transparent cover 110 is fixed on the mounting cantilever 222, and at least a portion of the display screen 120 is located on a side of the mounting cantilever 222 facing away from the transparent cover 110. After the installation cantilever 222 is arranged, a part of space can be reserved on the surface of the installation cantilever 222 opposite to the display screen 120, so that at least a part of the display screen 120 is accommodated, the non-display part at the edge of the display screen 120 is moved outwards as much as possible, and the size of the black edge of the mobile terminal is reduced.

Further, the higher the structural strength of the mounting arm 222 itself, the smaller the size thereof can be set, thereby further reducing the black edge size of the mobile terminal and increasing the screen occupation ratio of the mobile terminal. For this reason, the mounting cantilever 222 may be provided as a metal cantilever which is high in structural strength and thus can be suitably reduced in size. In this case, the other portion of the cover bezel 220 may be made of a non-metal material (e.g., plastic), and the mounting arm 222 may be formed by insert molding.

Of course, the size of the mounting arm 222 can be reduced in other ways, for example, the gap between the transparent cover 110 and the display module 100 is increased, so that the thickness of the mounting arm 222 is increased, and the width thereof can be reduced appropriately, thereby reducing the size of the black edge of the mobile terminal. Other high-strength materials may also be used to process and mount the cantilever 222, such as high-strength plastic materials (e.g., PA + 55% GF or stainless steel).

The embodiment of the utility model provides a disclosed mobile terminal can be for smart mobile phone, panel computer, electronic book reader or wearable equipment. Of course, the mobile terminal may also be other devices, and the embodiment of the present invention does not limit this.

The utility model discloses what the key description in the above embodiment is different between each embodiment, and different optimization characteristics are as long as not contradictory between each embodiment, all can make up and form more preferred embodiment, consider that the literary composition is succinct, then no longer describe here.

the above description is only an example of the present invention, and is not intended to limit the present invention. Various modifications and changes may occur to those skilled in the art.
