Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an electronic device. Background Technology

[0002] As users' demands for electronic devices increase, improving the screen-to-body ratio has become a key focus of electronic device research and development. In related technologies, the gap between the display module and the casing is often a significant factor contributing to black borders on electronic devices. If the gap is too large, the screen-to-body ratio is low; if the gap is too small, the display module is easily damaged by excess adhesive during assembly. Therefore, existing electronic devices often struggle to improve the screen-to-body ratio while ensuring the display module is not damaged by excess adhesive. Summary of the Invention

[0003] This application aims to provide an electronic device that solves the problem that existing electronic devices often struggle to increase screen-to-body ratio while ensuring that the display module is not damaged by excess adhesive.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] This application provides an electronic device, including:

[0006] A housing having an open mounting cavity, wherein an adhesive dispensing platform is provided on the inner wall of the mounting cavity;

[0007] A cover plate, the edge area of ​​which is connected to the dispensing station by dispensing adhesive and seals the open area of ​​the mounting cavity;

[0008] The display module is attached to the cover plate and located inside the mounting cavity;

[0009] An adhesive blocking component is movably disposed on the side of the dispensing platform near the display module, and the end of the adhesive blocking component away from the dispensing platform abuts against the cover plate.

[0010] In embodiments of this application, the electronic device may include a housing, a cover plate, a display module, and a glue-blocking assembly. The housing has a mounting cavity, the display module is connected to the cover plate and located within the mounting cavity, and a glue-blocking platform is formed on the inner wall of the mounting cavity. The glue-blocking assembly is disposed on the side of the glue-blocking platform near the display module, and the glue-blocking assembly is movable relative to the glue-blocking platform. Before assembling the cover plate into the electronic device, glue is applied to the glue-blocking platform. The glue-blocking assembly restricts the flow of the glue, preventing it from overflowing. During the installation of the cover plate onto the glue-blocking platform, the end of the cover plate away from the platform abuts against the glue-blocking assembly, causing the glue-blocking assembly to move relative to the platform. Thus, the glue is difficult to overflow towards the display module due to the glue-blocking assembly, effectively preventing damage to the display module from glue overflow. Furthermore, an excessively large gap is not required between the display module and the housing to ensure the display module is not damaged by glue overflow. Therefore, the black border width of the cover plate can be reduced, increasing the screen-to-body ratio of the electronic device.

[0026] The embodiments of this application will now be described in detail. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

Furthermore, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0029] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] In related technologies, the total black border width L of electronic devices typically consists of three parts: the width L1 of the dispensing platform, the gap width L2 between the display module and the housing, and the black border width L3 of the bending layer in the display module. Generally, the width L1 of the dispensing platform and the black border width L3 of the bending layer cannot be significantly adjusted due to design, manufacturing processes, and other factors. Therefore, reducing the gap width L2 between the display module and the housing is a feasible solution to improve the screen-to-body ratio of electronic devices. However, the inventors discovered that when the gap width L2 between the display module and the housing is small, during the assembly of the cover plate, the cover plate will squeeze the dispensing adhesive on the dispensing platform, resulting in adhesive overflow. Furthermore, due to the small gap width L2, there is a risk of adhesive overflowing onto the bending layer, potentially damaging the display module and increasing production costs.

[0031] Based on this, embodiments of this application provide an electronic device that can improve the screen-to-body ratio of the electronic device while ensuring that the display module is not damaged by excess adhesive. It is understood that the electronic device in these embodiments may include, but is not limited to, mobile phones, tablets, laptops, e-readers, educational devices, smartwatches, and game consoles.

[0032] The following is combined with Figures 1 to 8 The electronic device described is an embodiment of this application.

[0033] Please see Figure 1 and Figure 2 This application provides an electronic device, including a housing 1, a cover plate 2, a display module 3, and a sealant assembly 4. The housing 1 has an open mounting cavity, with a dispensing platform 11 on the inner wall of the cavity. The edge of the cover plate 2 is connected to the dispensing platform 11 via adhesive 111, thus closing the open area of ​​the mounting cavity. The display module 3 is attached to the cover plate 2 and located within the mounting cavity. The sealant assembly 4 is movably disposed on the side of the dispensing platform 11 near the display module 3, with the end of the sealant assembly 4 away from the dispensing platform 11 abutting against the cover plate 2.

[0034] like Figure 1 As shown, a dispensing stage 11 can be formed on the inner wall of the mounting cavity of the housing 1, and the adhesive blocking assembly 4 can be disposed on the dispensing stage 11, located on the side close to the display module 3. For example, Figure 1 The mounting cavity of the housing 1 is located on the right side, and the display module 3 is located inside the mounting cavity. The adhesive blocking assembly 4 can be placed on the right side of the dispensing platform 11. In this way, in order to prevent the dispensing adhesive 111 from overflowing onto the display module 3, the dispensing adhesive 111 can be placed on the area to the left of the adhesive blocking assembly 4 on the dispensing platform 11. Since the adhesive blocking assembly 4 is located on the right side of the dispensing platform 11, the contact area between the dispensing adhesive 111 and the edge area of ​​the cover plate 2 can be increased, thereby ensuring the assembly strength of the cover plate 2.

[0035] like Figure 2 As shown, during the installation of the cover plate 2 on the dispensing station 11, the adhesive blocking component 4 can move relative to the dispensing station 11. During this process, the cover plate 2 can be pressed along the first direction (X). The end of the cover plate 2, subjected to force, abuts against the adhesive blocking component 4 away from the dispensing station 11. With the downward pressing force, the adhesive blocking component 4 can move relative to the dispensing station 11. Throughout this process, the adhesive blocking component 4 can block the dispensing adhesive 111, thereby restricting the flow direction of the adhesive 111 and preventing it from overflowing onto the display module 3. Any adhesive 111 that overflows from the cover plate 2 can be wiped off according to the standard process.

[0036] In embodiments of this application, the electronic device may include a housing 1, a cover plate 2, a display module 3, and a glue-blocking assembly 4. The housing 1 has a mounting cavity, the display module 3 is connected to the cover plate 2 and located within the mounting cavity, and a glue-blocking platform 11 is formed on the inner wall of the mounting cavity. The glue-blocking assembly 4 is disposed on the side of the glue-blocking platform 11 near the display module 3, and the glue-blocking assembly 4 is movable relative to the glue-blocking platform 11. Before assembling the cover plate 2 into the electronic device, glue 111 is applied to the glue-blocking platform 11. The glue-blocking assembly 4 can restrict the flow of the glue 111, preventing the glue 111 from overflowing the glue-blocking platform 11. During the process of installing the cover plate 2 onto the glue-blocking platform 11, the end of the cover plate 2 away from the glue-blocking assembly 4 abuts against the glue-blocking platform 11, causing the glue-blocking assembly 4 to move relative to the glue-blocking platform 11. In this way, the adhesive 111 is difficult to overflow to the side near the display module 3 due to the obstruction of the adhesive blocking component 4, which can effectively prevent the display module 3 from being damaged by the overflow adhesive. At the same time, there is no need to set an excessively large gap between the display module 3 and the housing 1. Therefore, the black border width of the cover plate 2 can be reduced, and the screen ratio of the electronic device can be increased.

[0037] Optionally, in some embodiments, the dispensing station 11 is provided with a first groove, and the glue-blocking assembly 4 may include an elastic part 41 and a glue-blocking part 42. The elastic part 41 is disposed in the first groove, the first end of the glue-blocking part 42 is embedded in the first groove and connected to the elastic part 41, and the second end of the glue-blocking part 42 protrudes from the first groove. The cover plate 2 abuts against the second end of the glue-blocking part 42, and the cover plate 2 causes the elastic part 41 to deform, allowing the glue-blocking part 42 to move within the first groove.

[0038] In this embodiment, as Figure 1 and Figure 2 As shown, a first groove can be formed on the dispensing table 11, and the adhesive blocking component 4 can be disposed in the first groove. For example, the adhesive blocking component 4 may include an elastic part 41 and an adhesive blocking part 42. The elastic part 41 can be disposed in the first groove, and can be fixedly connected to the bottom of the first groove, or it can be placed in the first groove and contacting the bottom of the first groove. The first end of the adhesive blocking part 42 can be embedded in the first groove and connected to the elastic part 41, while the second end of the adhesive blocking part 42 can protrude from the first groove to block the flow of the dispensing adhesive 111.

[0039] During the process of installing the cover plate 2 on the dispensing table 11, the cover plate 2 abuts against the second end of the glue-blocking part 42 under the action of extrusion force. At this time, the glue-blocking part 42 is under force, and the elastic part 41 can deform, so that the glue-blocking part 42 can move in the first groove and move relative to the dispensing table 11 until the cover plate 2 is installed. The glue-blocking part 42 moves together with the cover plate 2 to the appropriate position.

[0040] It is understood that the elastic part 41 can be a deformable structure made of elastic material, or a component such as a spring, and no specific limitation is made here. The cross-section of the adhesive blocking part 42 can match the shape of the first groove, so that the adhesive blocking part 42 can better fit the groove wall of the first groove and effectively prevent the adhesive 111 from seeping into the first groove.

[0041] Optionally, in some embodiments, the extension direction of the first groove forms an angle with the cover plate 2, and the distance between the opening of the first groove and the display module 3 is less than the distance between the bottom of the first groove and the display module 3.

[0042] Please see Figure 3 and Figure 4 In this embodiment, the extending direction of the first groove may form an angle with the cover plate 2. In other words, the first groove may be an inclined groove, and the distance between the opening of the first groove and the display module 3 is less than the distance between the bottom of the first groove and the display module 3. For example, the opening of the first groove may be inclined towards the display module 3 relative to the vertical direction.

[0043] Understandably, to ensure the integrity and reliability of the original structure, the grooving process typically requires that the distance between the first groove and the inner wall of the mounting cavity meet minimum wall thickness requirements. Based on this, if... Figure 3 As shown, by opening an inclined groove, the glue-blocking part 42 is inclined towards the display module 3, which can increase the contact area between the glue 111 and the cover plate 2, thereby improving the assembly firmness of the cover plate 2.

[0044] In addition, when the cover plate 2 is not installed on the dispensing table 11, the elastic part 41 is in an uncompressed state, and the glue-blocking part 42 will protrude a large part outside the inclined groove, forming a groove with the housing 1 with the groove opening larger than the groove bottom, which is used to place the dispensing glue 111. In this way, even if the dispensing glue 111 with better fluidity is put in, the glue-blocking part 42 will have a good blocking effect on it.

[0045] like Figure 4 As shown, during the process of installing the cover plate 2 on the dispensing table 11, the cover plate 2 can be squeezed along the first direction (X), so that the cover plate 2 abuts against the end of the glue-blocking part 42 exposed in the inclined groove under the action of the squeezing force, and drives the glue-blocking part 42 to move in the inclined groove. At this time, the glue-blocking part 42 can move relative to the dispensing table 11 until the cover plate 2 is installed.

[0046] Optionally, in some embodiments, the elastic part 41 is a spring. For example... Figures 1 to 4 As shown, in this embodiment, the elastic part 41 can be a spring. When the cover plate 2 is not installed on the dispensing table 11, the spring is in an extended state, causing a large portion of the adhesive-blocking part 42 to protrude outside the first groove. During the installation of the cover plate 2 on the dispensing table 11, the spring is compressed, and the adhesive-blocking part 42 can be displaced within the first groove in a direction perpendicular to the cover plate 2. This embodiment uses a spring as the elastic part 41, which simplifies the structure and improves the convenience of assembling the cover plate 2.

[0047] Optionally, in some embodiments, the adhesive baffle 42 may include a metal adhesive baffle plate and a sealing layer, with at least a portion of the metal adhesive baffle plate disposed within the first groove; the sealing layer is sleeved on the metal adhesive baffle plate and contacts the inner wall of the first groove.

[0048] In this embodiment, to ensure the blocking effect of the dispensing adhesive 111, the adhesive-blocking part 42 can be made of a metal adhesive-blocking plate with high hardness. This can prevent the adhesive-blocking part 42 from deforming under pressure during the installation of the cover plate 2, thus avoiding adhesive overflow. A sealing layer can be sleeved on the outside of the metal adhesive-blocking plate. This sealing layer can be formed of a material with good sealing properties, such as plastic or nanomaterials. When at least a part of the metal adhesive-blocking plate is disposed in the first groove, the sealing layer contacts the inner wall of the first groove, which can prevent the dispensing adhesive 111 from seeping into the first groove along the gap between the inner wall of the first groove and the metal adhesive-blocking plate.

[0049] Optionally, in some embodiments, a buffer layer 421 is provided at one end of the adhesive-blocking assembly 4 near the cover plate 2, and the buffer layer 421 abuts against the cover plate 2.

[0050] In this embodiment, as Figures 1 to 3 As shown, a buffer layer 421 can be provided at the end of the adhesive-blocking assembly 4 that abuts against the cover plate 2. For example, plastic can be embedded in the end of the adhesive-blocking part 42 that is exposed in the first groove by injection molding. The plastic can reduce the contact stress between the cover plate 2 and the adhesive-blocking part 42, thereby avoiding damage to the cover plate 2.

[0051] Optionally, in some embodiments, the adhesive-blocking assembly 4 may include an elastic body 43 and a limiting part 44. The elastic body 43 is disposed on the dispensing stage 11, and the limiting part 44 is disposed on the dispensing stage 11, with the limiting part 44 located on the side of the elastic body 43 closer to the display module 3. The cover plate 2 abuts against the elastic body 43, causing the elastic body 43 to deform and move relative to the dispensing stage 11. The limiting part 44 restricts the displacement of the elastic body 43 toward the display module 3.

[0052] Please see Figure 5 In this embodiment, the adhesive blocking assembly 4 may include an elastic body 43 and a limiting part 44. The elastic body 43 may be disposed on the dispensing stage 11 to block the flow of dispensing adhesive 111. During the installation of the cover plate 2 on the dispensing stage 11, the elastic body 43 may abut against the cover plate 2 and deform under the pressure of the cover plate 2, causing it to move relative to the dispensing stage 11. The limiting part 44 may be disposed on the side of the elastic body 43 near the display module 3 and connected to the dispensing stage 11. Thus, when the elastic body 43 deforms, the limiting part 44 can block the elastic body 43, thereby limiting the displacement of the elastic body 43 towards the display module 3 during deformation. Therefore, it can be prevented that the elastic body 43, after deformation, comes into contact with the display module 3, thereby preventing damage to the display module 3.

[0053] It is understandable that the limiting part 44 can be fixedly set on the dispensing stage 11, or it can be set on the dispensing stage 11, as long as it can limit the displacement of the elastomer 43 toward the display module 3, and no specific limitation is made here.

[0054] Optionally, in some embodiments, the dispensing station 11 is provided with a second groove, one end of the limiting part 44 is connected to the elastic body 43, and the other end of the limiting part 44 extends into the second groove, wherein the limiting part 44 moves within the second groove when the elastic body 43 is deformed.

[0055] Understandably, in order for the cover plate 2 to be successfully installed on the dispensing table 11, the height of the limiting part 44 should not exceed the height of the cover plate 2 after the cover plate 2 is assembled. It can be seen that the setting of the limiting part 44 has a height limitation.

[0056] To further prevent part of the elastomer 43 from being exposed through the gap between the limiting part 44 and the cover plate 2 during deformation, and thus coming into contact with the display module 3, such as... Figure 6 As shown, in this embodiment, a second groove can be formed on the dispensing table 11. One end of the limiting part 44 can be connected to the elastic body 43, and the other end of the limiting part 44 extends into the second groove and can move within the second groove. For example, during the process of installing the cover plate 2 on the dispensing table 11, the elastic body 43 is compressed and deformed, causing the limiting part 44 to move relative to the dispensing table 11.

[0057] In this embodiment, the limiting part 44 is connected to the elastic body 43, and one end extends into the second groove, achieving horizontal limiting. Therefore, the displacement of the elastic body 43 toward the display module 3 can be restricted. In addition, the limiting part 44 can move within the second groove. In other words, it can move with the elastic body 43 relative to the dispensing platform 11. When it is set on the dispensing platform 11, it is not affected by height restrictions, thereby improving the limiting effect and effectively reducing the risk of damage to the display module 3.

[0058] Optionally, please refer to Figure 7 and Figure 8 In some embodiments, the limiting part 44 may include a connector 441 and a limiting part 442. The first end of the connector 441 is fixedly connected to the end of the elastomer 43 away from the dispensing table 11. The first end of the limiting part 442 is connected to the second end of the connector 441, and the second end of the limiting part 442 extends into the second groove.

[0059] To further improve the limiting effect of the limiting part 44, the limiting part 44 may include a connecting member 441 and a limiting member 442 connected to each other. The connecting member 441 is also fixedly connected to the end of the elastic body 43 away from the dispensing stage 11, and the end of the limiting member 442 away from the connecting member 441 extends into the second groove to achieve horizontal limiting. For example, as... Figure 7 As shown, the limiting part 44 can be L-shaped to wrap the elastic body 43, so that the elastic body 43 cannot be exposed when it deforms, thereby further improving the effect of limiting the displacement of the elastic body 43 toward the display module 3, and further reducing the risk of damage to the display module 3.

[0060] like Figure 8 As shown, during the process of installing the cover plate 2 on the dispensing station 11, the cover plate 2 abuts against the connector 441, causing the elastic body 43 to deform. At this time, the limiting member 442 also moves in the second groove, so that the entire glue blocking assembly 4 can move relative to the dispensing station 11 and can prevent the glue 111 from overflowing to the position of the display module 3.

[0061] It is understandable that, in order to reduce the contact stress between the cover plate 2 and the limiting part 44 and thus avoid damage to the cover plate 2, the limiting part 44 may be made of plastic material, or a buffer layer 421 may be provided at the contact position between the cover plate 2 and the limiting part 44. No specific limitation is made here.

[0062] Optionally, in some embodiments, one end of the elastomer 43 near the dispensing stage 11 is fixedly connected to the dispensing stage 11.

[0063] In this embodiment, the elastomer 43 can be fixedly mounted on the dispensing platform 11 by means of adhesive or other methods. This can prevent the dispensing adhesive 111 from seeping out from the contact gap between the elastomer 43 and the dispensing platform 11, thereby preventing the phenomenon of dispensing adhesive 111 leakage into the second groove.

[0064] Other components of the electronic device according to the embodiments of this application, such as cameras, speakers, and control chips, as well as their operation, are known to those skilled in the art and will not be described in detail here.

[0065] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application.
