The joint filling glue scheme has the disadvantages that the process is complex, the consumption of glue materials is high, the cost is increased, and the joint filling glue scheme cannot be applied to common electronic equipment.

Disclosure of Invention

The embodiment of the application provides electronic equipment, which is used for solving the problem that a display screen of the electronic equipment is wide in black edge.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical solutions:

the application provides an electronic device, including display screen, center and first gluey material. Specifically, the display screen includes apron and display module assembly, and the apron sets up with display module assembly range upon range of. The center includes the frame, and the display screen sets up in the inboard of frame. The frame comprises a first part and a second part, and the first part is at least opposite to the side face of the cover plate. The second part is at least opposite to the side surface of the display module, and the inner surface of the second part is provided with a boss. And the side surface of the cover plate, the inner surface of the first part and the side surface of the boss enclose a gap. A first rubber material is arranged in the gap. Compared with the prior art, the fixed position of display screen shifts to the side of apron by the bottom surface of original apron. The inner wall of the frame also eliminates the original ladder for supporting the cover plate. Therefore, the black edge of the display screen is further reduced, and the use experience of a user is improved.

In one possible implementation, at least part of the first glue material is connected with the side surface of the cover plate and the inner surface of the first part at the same time. The cover plate is connected to the inner surface of the first portion through the first rubber material, and then the cover plate is fixed in the frame. And the material consumption is less, so that the production cost of the electronic equipment is saved.

Further, the boss can be used for supporting the first gluey material in the gap, and first gluey material is fixed in the inner wall of frame with the display screen. In the process of injecting the first adhesive material, the boss can support the first adhesive material, so that excessive overflow of the first adhesive material is avoided, and the cost is saved.

In one possible implementation, the width of the gap between the inner surface of the first portion and the side surface of the cover plate is a first width. The height of the inner surface of the boss projecting beyond the second portion is less than or equal to the first width. The side surface of the cover plate, the inner surface of the first part and the side surface of the boss form a gap. That is to say, the width of gap is also first width, and the gap is used for holding first gluey material, and the width of first gluey material is less than or equal to first width. The boss is used for supporting the first glue material in the gap. Therefore, the height of the inner surface of the second part protruding out of the boss is set to be smaller than or equal to the first width, so that sufficient supporting force can be provided for the first adhesive material, and further the first adhesive material provides sufficient bonding strength for bonding between the display screen and the frame.

In a possible implementation manner, the middle frame further includes a middle plate, the middle plate is located inside the side frame, and an edge of the middle plate is fixed to an inner surface of the side frame. The middle plate and the frame enclose into a first accommodating groove, and the display screen is accommodated in the first accommodating groove. A buffer is arranged between the display screen and the middle plate. In one possible implementation, the buffer may be foam. The middle plate may divide the receiving cavity into two chambers. The display screen is accommodated in the first accommodating groove. Other electronic components are disposed in the other chamber, including but not limited to a circuit board, a processor, a camera, a flash, a microphone, a battery, etc. Will hold the chamber through the medium plate and divide into two cavities, be favorable to separation electronic component's heat transmission to the display screen, and then protect the display screen.

Further, compare in current joint sealant scheme, set up the bubble cotton between display screen and medium plate, support the display screen through the cotton substitution gum of bubble. Because the foam does not have the adhesive force, when the electronic equipment needs to be disassembled, the foam can not be adhered to the bottom of the display module to cause the layering problem. In addition, compared with the back adhesive, the cost of the foam is lower, and the cost of the electronic equipment is further reduced.

In one possible implementation, the cover plate includes opposing first and second surfaces. Specifically, the first surface sets up back to the display module assembly, and the second surface sets up towards the display module assembly. The side face of the cover plate is connected between the first surface and the second surface, the side face of the cover plate is connected with the first surface and the second surface, and the side faces of the first surface, the second surface and the cover plate are all planes. Set up first gluey material between the side of apron and the inner wall of frame, first gluey material contacts with the side of apron. The planar side face can provide a larger bonding area for the connection of the cover plate and the frame, so that the connection of the cover plate and the frame is more stable.

In one possible implementation, the cover plate includes opposing first and second surfaces. Specifically, the first surface sets up back to the display module assembly, and the second surface sets up towards the display module assembly. The side of apron is connected between first surface and second surface, and the side of first surface, second surface and apron is the plane, and the side of apron meets with the second surface, is connected with circular arc transition surface between the side of apron and the first surface, and circular arc transition surface meets with the side of apron, first surface, and the radius of circular arc transition surface is less than or equal to 0.03 mm. An arc transition surface is arranged between the first surface and the side surface of the cover plate for connection, so that the effect of a curved screen is achieved. The curved surface display screen can improve the sense organ experience of the user, has more comfortable wearing experience, and has better three-dimensional display effect. And the radius of circular arc transition surface sets up to be less than or equal to 0.03mm, when improving user experience, also can satisfy the bonding area between apron and the frame for the apron is connected more stably with the frame.

In a possible implementation manner, the cover plate further comprises an anti-fingerprint coating, and the anti-fingerprint coating is arranged on the first surface. The material of the anti-fingerprint coating is mainly perfluoropolyether polymer, and has the characteristics of fluorine-containing polymer, such as oleophobicity, low friction coefficient and hydrophobicity. Better anti-friction and anti-fouling properties can be obtained by providing the anti-fingerprint coating. The smoothness of the surface of the display screen can be effectively improved, and the friction between fingers and the display screen is reduced.

In a possible implementation, the side surface of the cover plate is in direct contact with the first glue material. Because the material of the anti-fingerprint coating contains fluorine, the fluorine-containing material can reduce the bonding strength of the first glue material. Consequently, only set up at the first surface of apron and prevent the fingerprint coating, and the side of apron then is the glass body, through the glass body and the first material direct contact that glues of side, and then improve the bonding strength between apron and the frame inner wall.

In one possible implementation, the side of the cover plate is provided with an ink layer. Specifically, the printing ink layer directly contacts with the side face of the cover plate, the first glue material is located on one side, away from the cover plate, of the printing ink layer, and the first glue material directly contacts with the printing ink layer. When the first surface setting of apron was prevented the fingerprint coating, the side of apron also the spraying appears easily and is prevented the fingerprint coating. At this moment, the anti-fingerprint coating on the side can reduce the bonding strength between the cover plate and the frame, and is not favorable for the stability of the electronic equipment. Consequently, set up the printing ink layer through the side at the apron, the spraying is prevented that the fingerprint coating is covered by the printing ink layer on the side of apron for printing ink layer and first gluey material direct contact can improve the bonding strength between apron and the frame, and then improve electronic equipment's stability.

In a possible implementation manner, an end face of the first part, which is far away from the second part, is flush with the first surface of the cover plate. That is to say, the display screen wholly wraps up in the holding intracavity of frame. The frame provides omnidirectional protection for the display screen, the risk of garrulous screen in greatly reduced user's use.

In one possible implementation, the boss further includes a top surface, and the side surface of the boss is connected between the inner surface of the first portion and the top surface of the boss. Specifically, the side surface of the boss is inclined in a direction toward the middle plate from an end connected to the inner surface of the first portion to an end connected to the top surface of the boss. That is, the distance between the inclined surface of the boss and the middle plate is gradually reduced. The inclined plane of boss encloses the bottom surface in one-tenth gap, and the inclined plane has enlarged the space in gap to the direction slope that is close to the medium plate, can hold the first material of gluing of bigger volume in the gap, and first material of gluing provides bigger bonding strength for being connected between apron and the frame. When the first glue material is applied to the gap, part of the first glue material can also overflow to the side face of the display module along the inclined plane of the boss, and the overflow part of the first glue material can protect the display module.

In one possible implementation, the boss further includes a top surface that meets a surface of the middle plate facing the display screen. That is to say, in electronic equipment's thickness direction, the top surface of boss is vertical state, and then has guaranteed the planarization of first holding tank inner wall.

In one possible implementation, the height of the inner surface of the boss projecting out of the second portion is less than the first width. A second accommodating groove is formed between the side face of the display module and the surface of the boss. That is to say, a gap is left between the inclined plane of the boss and the cover plate, and the first rubber material can overflow into the second accommodating groove through the gap between the boss and the cover plate. The second glue material is the same as the first glue material and is connected into a whole. The second glue material in the second holding tank can play the effect of protection display module assembly.

In a possible implementation manner, the display module further includes a touch module, and the touch module is disposed between the cover plate and the display module.

The back case 20 forms a housing of the electronic apparatus 100 for protecting internal electronics of the electronic apparatus 100. The back case 20 may include a back cover 21 and a bezel 22. The back cover 21 is located on one side of the display module 11 away from the cover plate 12, and is stacked and spaced apart from the cover plate 12 and the display module 11. The frame 22 is located between the back cover 21 and the cover plate 12. The frame 22 is fixed on the back cover 21, for example, the frame 22 may be fixedly connected to the back cover 21 by glue, and the frame 22 may also be integrated with the back cover 21, that is, the frame 22 and the back cover 21 are an integral structural component. The cover 12 is fixed to the frame 22 by gluing. The cover plate 12, the back cover 21 and the frame 22 enclose an accommodating cavity 23 of the electronic device 100. The accommodation chamber 23 accommodates the display module 11, the circuit board, the camera, and the flash.

In some embodiments, referring to fig. 3, the middle plate 24 is disposed in the accommodating cavity 23, and the middle plate 24 is located on a side of the display module 11 away from the cover plate 12. The edge of the middle plate 24 is fixed to the rim 22. In some embodiments, the edge of the middle plate 24 is fixed to the side frame 22 by glue, and the middle plate 24 may also be formed integrally with the side frame 22, that is, the middle plate 24 and the side frame 22 are a structural member. The middle plate 24 divides the accommodating cavity into a first accommodating cavity 231 and a fourth accommodating cavity 232, and the display module 11 is located in the first accommodating cavity 231. Other electronic components, such as a battery and a circuit board, are disposed in the fourth receiving groove 232. The back cover 21 is fixed to the middle frame 25 with foam rubber 26. The whole body formed by connecting the middle plate 24 and the side frame 22 can also be called as a middle frame 25.

With continued reference to fig. 3, the display screen 1 is fixed on the frame 22. Specifically, the inner wall of the frame 22 is configured to be stepped, that is, the inner wall of the frame 22 includes a first inner surface 221 and a second inner surface 222, the first inner surface 221 and the second inner surface 222 are connected in an L shape, and the second inner surface 222 is a stepped surface. The display panel 1 is fixed to the bezel 22 by fixing the bottom wall of the edge portion of the cover plate 12 of the display panel 1 to the second inner surface 222. Specifically, the adhesive 3 is disposed between the bottom wall of the edge portion of the cover plate 12 and the second inner surface 222 of the bezel 22, and the display panel 1 is fixed to the second inner surface 222 through the adhesive 3. In this scheme, in order to guarantee bonding strength, the width W of second internal surface 222 is great, and display screen 1 need reserve certain width and the inner wall cooperation of frame 22, and can't show the image with frame 22 inner wall complex partial display screen 1, presents the black border effect, and then produces the effect of frame 22 broad, reduces the screen of display screen 1 and accounts for the ratio.

To increase the screen ratio of the display screen 1, please refer to fig. 4, and fig. 4 is a schematic cross-sectional view of the electronic device 100 of fig. 1 along the line a-a. The display screen 1 and the frame 22 can also be connected by means of caulking glue. Specifically, the cover plate 12 and the display module 11 are located in the accommodating cavity 23, and the cover plate 12 and the display module 11 are stacked. One part of the gap-filling glue is located between the side surface of the cover plate 12 and the frame 22, and the other part of the gap-filling glue is located between the side surface of the display module 11 and the frame 22. On this basis, still be provided with gum 33 between display screen 1 and the well board 24, gum 33 is used for supporting display screen 1 a certain height, prevents that display screen 1 and well board 24 from contacting.

Compared with the step matching mode in fig. 3, the step of the inner wall of the frame 22 is cancelled in the joint filling glue matching mode in fig. 4, so that the problem that the black edge of the display screen 1 is wide is avoided, and the screen impression experience of a user is improved. However, the problem of high cost is caused by complex process and large consumption of glue material, and the joint-filling glue matching method cannot be applied to low-end electronic devices 100.

The reason for the excessive cost is that the middle frame 25 may be damaged during the manufacturing process of the electronic device 100, and the cost of the display screen 1 is too high, so that the display screen 1 needs to be taken out of the damaged middle frame 25 and the display screen 1 needs to be installed in the intact middle frame 25. Specifically, the display panel 1 is entirely detached from the accommodating chamber 23 by the suction cover plate 12. Referring to fig. 4, since the back glue 33 is disposed between the display module 11 and the middle plate 24, the display module 11 is easily layered between the cover plate 12 and the display module 11 and between the layers inside the display module 11 during the disassembly process under the adhesive force of the back glue 33, which causes the display screen 1 to be damaged during the disassembly process. Therefore, the adhesive mode of the gap filling adhesive must make the adhesive material 3 overflow into the accommodating cavity 23 along the inner wall of the frame 22 too much, so that the side wall of the display module 11 keeps integral under the adhesion of the adhesive material 3, and the delamination problem is avoided. Therefore, the process of the joint compound is complex, and the consumption of the compound material 3 is too high, which causes the problem of too high cost, and thus the joint compound cannot be applied to the low-end electronic device 100.

To solve the above problem, please refer to fig. 5 and fig. 6, in which fig. 5 is a schematic cross-sectional view of the electronic device 100 of fig. 1 along a line a-a, and fig. 6 is an enlarged view of a region B of fig. 5.
