Description

a mobile terminal

technical field

The utility model relates to the technical field of terminals, in particular to a mobile terminal.

Background technique

As electronic products with touch screens become more and more popular, product differentiation becomes smaller and smaller, and ultra-narrow bezels have become a breakthrough point for major manufacturers to seek differentiation.

Referring to FIG. 1 , it is a schematic structural diagram of a conventional mobile terminal. Wherein, the mobile terminal includes a housing 10 and a display screen module 11 . The fixing methods of the display screen module 11 include: pasting with double-sided tape or pasting with liquid glue. Using double-sided adhesive tape requires a larger double-sided tape width to ensure the adhesive strength, which cannot meet the requirements of ultra-narrow borders. Therefore, at present, liquid glue is mainly used to realize ultra-narrow borders.

As shown in FIG. 1 , liquid glue is dotted on a step of the housing 10 , and a bottom surface of the display module 11 is connected to the dispensing area 12 at the top of the step. In order to narrow the frame as much as possible, the glue dispensing area 12 needs to be reduced as much as possible, and when the glue dispensing area 12 is small, the sticking strength of the glue will become smaller, making the display module easy to detach from the casing, affecting the user's use. Further, for the sake of aesthetics, generally, the gap between the side wall of the housing 10 and the display module 11 is set to about 0.05mm. Because the glue has a certain tension, it is difficult to flow water from the side wall through the gap. Therefore, the existing mobile terminal cannot provide glue between the side wall of the casing 10 and the display module 11 .

Utility model content

In view of the above problems, the utility model proposes a mobile terminal to solve the problem that the display module is easily detached from the casing due to the reduction of the dispensing area.

In order to solve the above problems, the utility model discloses a mobile terminal, comprising: a housing and a display module;

The housing has a cavity for accommodating the display screen module;

the sidewall of the cavity has a first step extending from the bottom of the cavity, and a second step extending from the top of the first step;

The side wall of the second step has a first groove;

Glue is provided on the top of the first groove and the first step, and the display screen module is connected to the housing through the glue.

The utility model comprises the following advantages:

In the embodiment of the utility model, grooves are provided on the side wall of the second step of the casing, so that liquid glue can flow into the side wall of the second step, and the dispensing area between the display module and the side wall of the second step is increased. This makes it possible to reduce the width of the first step to achieve an ultra-narrow frame while ensuring the bonding strength between the display module and the casing.

detailed description

In order to make the above purpose, features and advantages of the utility model more obvious and understandable, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Referring to FIG. 2, it shows a structural block diagram of a mobile terminal of the present invention, which may specifically include: a housing 20, a display module 21;

The housing 20 has a cavity 22 for accommodating the display module 21;

The side wall of the cavity 22 has a first step 23 extending from the bottom of the cavity 22, and a second step 24 extending from the top of the first step 23;

The side wall of the second step 24 has a first groove 25;

Adhesive 26 is provided on the top of the first groove 25 and the first step 23 , and the display module 21 is connected to the housing 20 through the adhesive 26 .

The first groove 25 is vertically connected to the top of the first step 23 .

In the embodiment of the present invention, by setting the first groove 25 on the side wall of the second step 24 of the housing 20, the liquid glue can flow into the side wall of the second step 24, increasing the connection between the display module 21 and the second step. The dispensing area between the side walls of the step 24. This makes it possible to reduce the width of the first step 23 to achieve an ultra-narrow frame, while ensuring the bonding strength between the display module 21 and the housing 20 .

Referring to FIG. 3 , it is a structural block diagram of a mobile terminal in an embodiment of the present invention. Wherein, the display screen module 21 includes: touch screen glass 27;

The touch screen glass 27 is connected to the top of the first step 23 and the first groove 25 through the glue 26 .

Specifically, the distance between the first groove 25 and the touch screen glass 27 is in the range of 0.1-0.15mm. The thickness of the glue between the first groove 25 and the touch screen glass 27 is in the range of 0.1-0.15mm.

When the width of the gap between the first groove 25 and the edge of the touch screen glass 27 is 0.1-0.15mm, the liquid glue can enter the sidewall of the first groove 25 through the gap. The glue flowing into the gap can fill the side wall space of the first groove 25 .

As shown in FIG. 3 , the display screen module 21 further includes: a display screen glass 28 connected to the touch screen glass 27;

The display glass 28 is accommodated in a space formed by the first step 23 and the bottom of the cavity 22 .

In the embodiment of the present utility model, there is optical glue 29 between the display screen glass 28 and the touch screen glass 27 , and the display screen glass 28 and the touch screen glass 27 are connected 29 through the optical glue.

In the embodiment of the present invention, the sidewall of the first step 23 has a second groove 30 , and the width 30 of the second groove is greater than the thickness of the display glass 28 .

As shown in FIG. 3 , the width of the frame refers to the distance A between the edge of the touch screen glass 27 and the edge of the display glass 28 . In fact, the width of the frame is equal to the sum of the width B of the adhesive area at the top of the first step 23 and the distance C between the display glass 28 and the surface of the side wall of the first step 23 . By setting the second groove 30 to utilize the sidewall area of the first step 24, the distance C between the display glass 28 and the surface of the sidewall of the first step 24 can be reduced, and the frame width can be reduced.

Further, the second groove 30 is vertically connected to the bottom of the cavity 22 . The width of the second groove 30 is greater than the distance from the side where the display glass 28 connects with the touch screen glass 27 to the bottom of the cavity 22 .

In the embodiment of the present utility model, there is a gap between the display glass 28 and the bottom of the cavity 22 .

The distance between the display glass 28 and the second groove 30 satisfies a preset safety distance.

In the embodiment of the present utility model, the distance between the display glass 28 and the second groove 30 satisfies a preset safety distance.

As shown in FIG. 3 , the preset safety distance D is the sum of the distance C between the display glass 28 and the surface of the sidewall of the first step 23 and the depth of the second groove 30 .

The preset safety distance is a distance required to make the display glass 28 and the second groove 30 not easily collide.

Due to lamination tolerances between the touch screen glass 27 and the display screen glass 28 , fabrication tolerances of the housing 20 , and assembly tolerances between the touch screen glass 27 and the housing 20 . In order to ensure that the collision between the display glass 28 and the second groove 30 is unlikely to occur, it is necessary to have a certain safety distance between the display glass 28 and the second groove 30 .
