DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In order to make the technical solutions and advantages of the present application clearer, the electronic device, etc. will be described in detail below in conjunction with the drawings.

[0038] With the development of mobile phone structure design and flexible screen technology, foldable mobile phones are becoming the focus of research and development of mobile phone manufacturers because they can be transformed into a pad or large-screen display after unfolding. Screen pressing blocks are usually set at the edge of the folding mobile phone screen to protect the bending area of ​​the folding screen.

[0039] In the related art, when assembling the screen pressing block and the shell, generally, a proper amount of glue is first filled into the glue groove on the shell, and then the screen pressing block is inserted into the glue groove and bonded by glue. However, due to the limited space in the groove, the amount of glue that can be accommodated is also limited, which easily leads to poor bonding or glue overflow.

[0040] In this regard, an embodiment of the present application provides an electronic device, such as Figure 1 and Figure 4 As shown, the electronic device includes a shell 1 and a screen pressing block 2; a glue dispensing groove 11 is opened on the shell 1, and the glue dispensing groove 11 is filled with glue 3; one end of the screen pressing block 2 is located in the glue dispensing groove 11, and is connected to the groove wall of the glue dispensing groove 11 through the glue dispensing 3; the glue dispensing groove 11 is provided with a first functional part 111, and the first functional part 111 is used to increase the bonding area between the glue dispensing groove 11 and the glue dispensing 3; and / or, the screen pressing block 2 is provided with a second functional part 21, and the second functional part 21 is used to increase the bonding area between the screen pressing block 2 and the glue dispensing 3.

[0041] The electronic device provided in the embodiment of the present application has a shell 1 and a screen pressing block 2 bonded together by glue 3, wherein a first functional part 111 is provided in the glue dispensing groove 11 of the shell 1, and / or a second functional part 21 is provided on the screen pressing block 2; when the amount of glue filled in the glue dispensing groove 11 is moderate or small, the first functional part 111 and the second functional part 21 are respectively used to increase the contact area between the screen pressing block 1 and the glue dispensing groove 11 and the glue dispensing 3, so as to enhance the bonding force between the screen pressing block 2 and the glue dispensing groove 11 and the glue dispensing 3; when the amount of glue filled in the glue dispensing groove 11 is large, since the first functional part 111 and the second functional part 21 can be bonded with more glue dispensing 3, it is equivalent to increasing the amount of glue dispensing that can be accommodated between the glue dispensing groove 11 and the screen pressing block 2, thereby enhancing the tolerance for the amount of glue dispensing between the glue dispensing groove 11 and the screen pressing block 2, and improving the bonding effect between the glue dispensing groove 11 and the screen pressing block 2. Therefore, the connection strength between the screen pressing block 2 and the shell 1 in the electronic device provided by the embodiment of the present application is high, thereby avoiding the occurrence of poor bonding or glue overflow.

[0042] It should be noted that one side of the glue dispensing groove 11 on the shell 1 is open, and the glue dispensing groove 11 includes four inner side walls and a bottom wall 112. The four inner side walls are connected end to end in sequence along the circumference of the opening and are respectively connected to the bottom wall 112. The bottom wall 112 is arranged opposite to the opening.

[0043] It should also be noted that if Figure 1 As shown, the screen pressing block 2 is usually provided with at least two overlapping parts 23. When one end of the screen pressing block 2 is extended into the glue dispensing groove 11, at least two overlapping parts 23 are overlapped on the edge of the opening of the glue dispensing groove 11, wherein the depth of the screen pressing block 2 extending into the glue dispensing groove 11 is less than the groove depth of the glue dispensing groove 11, so that the end of the screen pressing block 2 extending into the glue dispensing groove 11 is suspended, and an accommodating space for accommodating the glue dispensing 3 is formed between the screen pressing block 2 and the inner side wall of the glue dispensing groove 11 and the bottom wall 112.

[0044] Therefore, since the first functional part 111 and / or the second functional part 21 are provided, the volume of the accommodating space is indirectly increased, that is, the amount of glue 3 that can be accommodated is increased, which not only improves the connection strength between the screen pressing block 2 and the glue dispensing groove 11, but also reduces the risk of glue overflow caused by excessive glue dispensing 3, and improves the tolerance for the glue dispensing amount.

[0045] When the screen pressing block 2 and the housing 1 are assembled, generally, a proper amount of glue 3 is first filled in the glue dispensing groove 11, and then the screen pressing block 2 is inserted into the glue dispensing groove 11. When the screen pressing block 2 is inserted into the glue dispensing groove 11, the bottom surface 22 of the screen pressing block 2 will first contact the glue 3 and apply an extrusion force to the glue 3, so that the glue 3 is spread and more connected to the screen pressing block 2 and the groove wall of the glue dispensing groove 11.

[0046] In order to improve the connection strength between the screen pressing block 2 and the glue dispensing groove 11, in some embodiments of the present application, the second functional part 21 may include a first groove 211, and the first groove 211 is located on the bottom surface 22 of the screen pressing block 2, and the bottom surface 22 is the surface of the screen pressing block 2 facing and close to the bottom wall 112 of the glue dispensing groove 11.

[0047] During the bonding process of the screen pressing block 2 and the glue dispensing groove 11, the glue dispensing 3 in the glue dispensing groove 11 first contacts the bottom surface 22 of the screen pressing block 2, and under the squeezing action of the bottom surface 22, enters the interior of the screen pressing block through the first groove 211, fills the first groove 211 and adheres to the inner wall of the first groove 211, that is, the contact area between the glue dispensing 3 and the screen pressing block 2 is increased, and the remaining part of the glue dispensing 3 will be bonded and connected to the bottom surface 22 and / or side surface of the screen pressing block 2; and, because there is bonding force between the inner wall of the first groove 211 and the glue dispensing 3, and after the glue dispensing 3 solidifies, the various parts of the glue dispensing 3 have integrity, and there is a force between the glue dispensing 3 located inside the first groove 211 and the glue dispensing 3 located outside the first groove, so that the connection strength between the screen pressing block 2 and the glue dispensing groove 11 is greatly improved, and the bonding effect between the glue dispensing groove 11 and the screen pressing block 2 is improved.

[0048] Moreover, compared to the screen pressing block with a flat bottom surface 22, after the first groove 211 is set on the bottom surface 22 of the screen pressing block 2 in this embodiment, a portion of the glue 3 can be additionally accommodated through the inner cavity of the first groove 211, which is equivalent to increasing the capacity of the above-mentioned accommodating space 4. Therefore, even if the amount of glue filled in the glue groove 11 is large, it is not easy to overflow from the glue groove 11. That is, the solution of this embodiment improves the tolerance of the glue amount between the glue groove 11 and the screen pressing block 2, and reduces the risk of glue overflow.

[0049] In one example, the first groove 211 is opened on the bottom surface 22 of the screen pressing block 2, and the first groove 211 has only one open end, which faces the bottom wall 112 of the glue dispensing groove 11. When the glue dispensing 3 is squeezed by the screen pressing block 2, a part of it will enter the interior of the first groove 211, filling the first groove 211 and bonding with the inner wall of the first groove 211. The other part of the glue dispensing 3 will be bonded to the bottom surface 22 or even the side surface of the screen pressing block 2, thereby improving the connection strength between the screen pressing block 2 and the glue dispensing groove 11.

[0050] However, in some cases, such as when the first groove 211 has only one open end and is deep, it is difficult to completely fill the space inside the first groove 211 only by the extrusion force provided by the screen pressing block 2, and since there is air inside the first groove 211, it is even more difficult for the glue 3 to fill the interior of the first groove 211, resulting in a waste of space.

[0051] So, in another example, Figure 2 As shown, at least one side of the first groove 211 extends to at least one side surface of the screen pressing block 2 , and the side surface is a surface of the screen pressing block 2 adjacent to the bottom surface 22 .

[0052] by Figure 3 Taking the structure and orientation shown as an example, in addition to the open end located on the bottom surface 22 of the screen pressing block 2, the front side, left side and right side of the first groove 211 also extend to the front side surface, left side surface and right side surface of the screen pressing block 2 respectively, so that the first groove 211 is a structure open on four sides.

[0053] Based on the screen pressing block 2 with the above-mentioned first groove 211, during the bonding process between the screen pressing block 2 and the glue dispensing groove 11, the glue dispensing 3 is deformed under the action of the extrusion force, and can enter the first groove 211 from the opening end of the first groove 211 on the bottom surface 22 of the screen pressing block 2, or from the opening of the first groove 211 on other surfaces of the screen pressing block 2. Compared with the first groove 211 with only one opening end, the glue dispensing 3 in this example can be more easily filled into the first groove 211, and the waste of space is avoided, thereby increasing the contact area between the first groove 211 and the glue dispensing 3, thereby improving the bonding strength between the screen pressing block 2 and the glue dispensing groove 11. Moreover, the gas inside the first groove 211 can be discharged from any opening of the first groove 211, and will not cause any influence on the filling of the glue dispensing 3.

[0054] Furthermore, during the preparation process of the glue dot 3, tiny bubbles may exist inside it; when the glue dot 3 enters the first groove 211 under the extrusion force, the inner wall of the first groove 211 will also produce an extrusion force on the glue dot 3, so that the gas inside the glue dot 3 can be discharged, thereby further increasing the bonding area between the first groove 211 and the glue dot 3.

[0055] It is easy to understand that during the use of the electronic device, the screen pressing block 2 is easily pulled by external force and slips out of the glue dispensing groove 11 under the action of external force. Since the glue dispensing 3 is bonded to the inner wall of the first groove 211 of the screen pressing block 2, the glue dispensing 3 is subject to the same external force as the screen pressing block 2; and since the opening direction of the opening end of the first groove 211 is parallel to the opening direction of the glue dispensing groove 11, the external force is specifically manifested as a shear force on the glue dispensing 3. Under the action of this shear force, the bonding between the glue dispensing 3 and the inner wall of the first groove 211 is prone to failure.

[0056] Therefore, in some embodiments of the present application, Figure 3 As shown, the first groove 211 may include a glue injection section 2111 and a glue storage section 2112; one end of the glue injection section 2111 is located on the bottom surface 22, the other end of the glue injection section 2111 is connected to the glue storage section 2112, and the axis of the glue injection section 2111 intersects with the axis of the glue storage section 2112.

[0057] The glue dots 3 filled in the glue entry section 2111 and the glue storage section 2112 are integral, that is, there is a force between the glue dots 3 in the glue entry section 2111 and the glue dots 3 in the glue storage section 2112. Therefore, when the glue dots 3 are subjected to the above-mentioned external force, only a part of the external force will act on the glue entry section 2111 in the form of shear force, and the rest of the external force will act on the glue storage section 2112 in the form of tension to overcome the adhesion between the glue dots 3 and the glue storage section 2112, and in the form of tension to overcome the adhesion between the glue dots 3 and the groove wall of the glue dots groove 11, so it is less likely to cause the adhesion failure between the glue dots 3 and the screen pressing block 2, that is, the risk of the screen pressing block 2 falling off and loosening is reduced.

[0058] Optionally, at least one end of the glue storage section 2112 extends to the side surface to communicate with the glue dispensing groove 11, so as to increase the surface area of ​​the glue storage section 2112 as much as possible and improve the bonding strength.

[0059] Those skilled in the art can select and adjust the angle between the axis of the glue feeding section 2111 and the axis of the glue storage section 2112 according to actual needs. Figure 3 As shown, the axis of the glue entry section 2111 is perpendicular to the axis of the glue storage section 2112 to minimize the shear force on the glue dispenser 3 .

[0060] Optionally, the axis of the glue entry section 2111 passes through the center of the glue storage section 2112. After the glue dots 3 enter the glue entry section 2111 and the glue storage section 2112, the glue dots 3 in the glue entry section 2111 and the glue storage section 2112 are perpendicular to each other, and the glue dots 3 in the glue storage section 2112 are symmetrically arranged about the axis of the glue entry section 2111, so that the glue dots on both sides of the axis of the glue entry section 2111 are equal, and the tensile forces that can be withstood are equal, thereby reducing the probability of the screen pressing block 2 tilting under the action of external force after bonding.

[0061] In order to further increase the contact area between the screen pressing block 2 and the glue dispensing 3 to enhance the connection strength between the two, in some embodiments of the present application, the number of the first grooves 211 may be multiple, and the multiple first grooves 211 are distributed on the bottom surface 22 at intervals.

[0062] In one example, if Figure 4 As shown, a plurality of first grooves 211 are spaced apart on the bottom surface 22 of the screen pressing block 2, so that the bottom of the screen pressing block 2 is corrugated as a whole. When the glue 3 in the glue dispensing groove 11 is subjected to the extrusion force, it will be filled into the plurality of first grooves 211 and adhered to the inner walls of the plurality of first grooves 211, further increasing the contact area between the screen pressing block 2 and the glue 3.

[0063] In some embodiments, the plurality of first grooves 211 may be distributed at intervals along the length direction of the bottom surface 22 of the screen pressing block 2, or may be distributed at intervals along the width direction of the bottom surface 22, or may be distributed at intervals along the diagonal direction of the bottom surface 22. Those skilled in the art may select and adjust the arrangement direction of the first grooves 211 according to actual needs and processing difficulty.

[0064] Furthermore, if Figure 4 As shown, the first functional portion 111 may include a plurality of second grooves 1111 opened on the bottom wall 112 ; wherein each first groove 211 is opposite to at least one second groove 1111 .

[0065] When the first groove 211 is facing the second groove 1111, a glue holding space is formed between the first groove 211 and the second groove 1111. The glue in the glue holding space has a greater thickness after solidification, thereby improving the connection strength between the screen pressing block 2, the glue 3 and the glue groove 11.

[0066] Optionally, those skilled in the art may select and adjust the number of the first grooves 211 and the second grooves 1111 according to actual needs.

[0067] In another example, the first groove 211 includes a plurality of glue injection sections 2111 and a corresponding plurality of glue storage sections 2112 , and the plurality of glue injection sections 2111 are spaced apart and distributed on the bottom surface 22 , thereby increasing the contact area.

[0068] The second functional part 21 in the above embodiment is arranged on the screen pressing block 2, and the screen pressing block 2 needs to be processed. However, the size of the screen pressing block 2 is generally small, and it is difficult to process multiple grooves on the bottom surface 22 of the screen pressing block 2, and the requirements for processing tools are high. Therefore, in some embodiments of the present application, the first functional part 111 may include a third groove 1112 opened on the inner side wall of the glue dispensing groove 11, and one side of the third groove 1112 is connected to the bottom wall 112 of the glue dispensing groove 11.

[0069] By machining a third groove 1112 on the inner wall of the glue dispensing groove 11, the glue 3 in the glue dispensing groove 11 will be filled into the third groove 1112 under the action of the extrusion force, and the contact area between the glue dispensing groove 11 and the glue 3 can be increased, thereby reducing the risk of the screen pressing block 2 falling off and loosening. In addition, the size of the shell 1 is larger, which is convenient for clamping and reduces the difficulty of processing.

[0070] In some embodiments, the number of the third groove 1112 is one, and the third groove 1112 is an annular groove extending along the circumference of the glue dispensing groove 11. It has a simple structure and is easy to process. It increases the contact area between the glue dispensing groove 11 and the glue 3, and improves the connection strength between the screen pressing block 2 and the glue dispensing groove 11.

[0071] In some embodiments, Figure 5 As shown, the number of the third grooves 1112 is two, and the third grooves 1112 are bevel grooves extending along the length direction of the glue dispensing groove 11, and the two third grooves 1112 are arranged on opposite sides of the glue dispensing groove 11. Since the length direction of the screen pressing block 2 is parallel to the length direction of the glue dispensing groove 11, the contact area of ​​the glue dispensing groove 11 with the glue dispensing 3 in the width direction has little effect on the connection strength. Therefore, compared with the annular groove, in the electronic device provided in this embodiment, although the number of the third grooves 1112 is increased, the processing workload, such as the cutting distance, is reduced, thereby reducing the processing time and processing cost.

[0072] In some embodiments, the number of third grooves 1112 can be multiple, and the multiple third grooves 1112 are evenly distributed on opposite sides of the glue dispensing groove 11, which further reduces the processing cost. The number of third grooves 1112 is increased, and the staggered arrangement is equivalent to reducing the volume of the third grooves 1112. Since the amount of glue in the glue dispensing groove 11 is limited, under this setting, the glue 3 is easier to fill into the third groove 1112 under the action of the extrusion force, and the filling effect is better.

[0073] For example, Figure 6 As shown, the number of the third grooves 1112 is six, which are respectively arranged on two opposite sides of the glue dispensing groove 11. Optionally, those skilled in the art can select and adjust the number of the third grooves 1112 according to actual needs.

[0074] In the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless otherwise clearly defined.

[0075] Those skilled in the art will readily appreciate other embodiments of the present application after considering the specification and practicing the utility model disclosed herein. The present application is intended to cover any variations, uses or adaptations of the present application, which follow the general principles of the present application and include common knowledge or customary technical means in the art that are not disclosed in the present application.
