Description

Sealing method for structural parts and electronic equipment

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 26, 2023, with application number 202311818637.7 and application name “Sealing method for structural parts and electronic equipment”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of sealing technology, and in particular to a sealing method for a structural component and an electronic device. Background Art

[0003] With the rapid development of power electronics technology, the types and functions of electronic products are expanding, and people are demanding higher and higher levels of waterproof performance for consumer electronic products such as mobile phones, tablets, laptops, and wearable devices. Electronic products typically consist of multiple components, and during assembly, through-holes are typically provided on the components for connection. Connectors are placed in these through-holes to connect two components, creating gaps between the connectors and the inner walls of the through-holes, as well as between adjacent components. To meet the waterproof specifications for consumer electronic products, these gaps need to be sealed.

[0004] Typically, gaps in electronic products are sealed by pouring glue directly into them, relying on the sealant's inherent fluidity. However, low glue viscosity can easily lead to overflow and leakage. High glue viscosity can make it difficult to effectively fill irregular and micro-shaped gaps. To address these issues, negative pressure is applied to the exterior surface of the gap, allowing the higher-viscosity glue to fill the gap under the influence of negative pressure.

[0005] However, although applying negative pressure on the outer surface of the gap can allow glue with higher viscosity to enter the gap, it cannot solve the problem of glue overflow or leakage of the product. Summary of the Invention

[0006] The present application provides a sealing method for a structural component and an electronic device, wherein the sealing method for a structural component can effectively solve the problems of glue overflow and glue leakage of the product.

[0007] A first aspect of an embodiment of the present application provides a method for sealing a structural member, the method comprising providing a structural member, the structural member comprising a first structural member and a second structural member, a sealing channel being provided between the first structural member and the second structural member, the sealing channel comprising a first opening and a second opening. The structural member is placed in a first environment, and the second opening is in a sealed state. A preset volume of sealant is injected into the sealing channel from the first opening, and in the first environment, the sealant automatically flows toward the second opening. After a first preset time, the structural member is placed in a second environment, the pressure of the second environment being greater than the pressure of the first environment, so that the sealant is sealed and filled in the sealing channel under the pressure difference between the second environment and the first environment.

[0008] The structural member sealing method provided by the embodiment of the present application can prevent the problem of glue overflow or glue leakage after the sealing channel is sealed by sealing the second opening of the sealing channel, and can control the amount of sealant used. By placing the structural member in the first environment first, and injecting a preset volume of sealant into the sealing channel at the first opening, the amount of sealant used can be controlled, and the sealant can be injected into the sealing channel. After the first preset time, the structural member is placed in the second environment, so that part or all of the sealant can be injected into the sealing channel when the sealant is in the first environment. By setting the pressure of the second environment to be greater than the pressure of the first environment, the pressure difference between the second environment and the first environment can be used to seal and fill the remaining part of the sealant or all of the sealant entering the sealing channel into the sealing channel, ensuring that the special-shaped and micro-gap positions in the sealing channel can be effectively filled. In addition, the sealant is squeezed by positive pressure to fill the sealing channel, which can reduce the risk of bubbles in the sealant compared to filling by pumping negative pressure.

[0009] In a possible implementation, before or after placing the structural component in the first environment, the method further includes providing a sealing structure at the second opening for sealing the second opening, so that the second opening is in a sealed state.

[0010] By providing a sealing structure for sealing the second opening, the second opening is kept sealed, thereby preventing glue leakage or overflow at the second opening. Furthermore, the outer side of the second opening is kept relatively flat, ensuring a neat and aesthetically pleasing appearance when the second opening faces the exterior surface of the structural component.

[0011] In a possible implementation, placing the structural component in the second environment further includes, after a second preset time, removing the sealing structure from the second opening.

[0012] After the structural member is placed in the second environment, the sealing mechanism is removed from the second opening after a second preset time, so that there are no redundant parts on the structural member, thereby simplifying the structure of the structural member, and when the second opening faces the appearance surface of the structural member, the aesthetics of the structural member can be improved.

[0013] In a possible implementation, the sealing structure includes a peelable sealant.

[0014] By configuring the sealing structure to include a peelable sealant, it is convenient to remove the sealing structure after the sealing channel is sealed, which can reduce the difficulty of removing the sealing structure and further reduce the sealing cost of the structural member.

[0015] In a possible implementation, the sealing structure includes a clamp, wherein a partial structure of the clamp is disposed at the second opening and is sealed and connected to the second opening.

[0016] By configuring the sealing structure to include a clamp, the second opening can be sealed by simply placing the structural member on the clamp and performing certain operations. This simplifies the procedure for sealing the second opening of the sealing channel and improves the sealing efficiency of the structural member.

[0017] In a possible implementation, providing the structural member includes forming an appearance surface on at least one of the first structural member and the second structural member, and the second opening extends to the appearance surface.

[0018] By forming an appearance surface on at least one of the first structural member and the second structural member and extending the second opening to the appearance surface, when the sealing channel is sealed, it can be ensured that there is no glue leakage or overflow on the appearance surface of the structural member, and the appearance surface can be guaranteed to be flat and beautiful.

[0019] In a possible implementation, the first environment is a negative pressure environment.

[0020] When the first environment is set to a negative pressure environment, the second environment can be set to a standard atmospheric pressure environment or an air environment, so that a pressure difference is formed between the second environment and the first environment, thereby ensuring that the special-shaped and micro-gap positions in the sealing channel can be effectively filled. In addition, the sealant is squeezed by positive pressure to fill the sealing channel, which can reduce the risk of bubbles in the sealant compared to filling by pumping negative pressure. In addition, it is only necessary to provide a negative pressure environment and release the pressure of the first environment after a first preset time. The operation is simple and the steps of sealing the structural parts can be simplified. In addition, the negative pressure environment is easy to provide, and the air environment is also easy to provide, so this can reduce the cost of sealing the structural parts.

[0021] In a possible implementation, the first environment is a standard atmospheric pressure environment or an air environment.

[0022] When the first environment is set to a standard atmospheric pressure environment or an air environment, the second environment can be set to an environment with a higher air pressure than a standard atmospheric pressure environment or an air environment. This will create a pressure difference between the second environment and the first environment, thereby ensuring that the irregular shapes and micro-gap positions in the sealing channel can be effectively filled. In addition, the sealant is squeezed under positive pressure to fill the sealing channel, which can reduce the risk of bubbles in the sealant compared to filling with negative pressure. In addition, a standard atmospheric pressure environment or an air environment is easy to obtain, and to obtain the second environment, it is only necessary to pressurize the first environment, which is convenient to operate, thus reducing the cost of sealing the structural parts.

[0023] In one possible implementation, when the first environment is a negative pressure environment, before injecting a preset volume of sealant into the sealing channel through the first opening, the method further includes obtaining the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component. The negative pressure value of the first environment is adjusted based on one or more of the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component.

[0024] By obtaining the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural parts, and the surface treatment method of the structural parts before injecting a preset volume of sealant into the sealing channel from the first opening, and adjusting the negative pressure value of the first environment according to one or more of the above parameters, the accuracy of the negative pressure value of the first environment can be improved, thereby improving the sealing efficiency.

[0025] In one possible implementation, when the first environment is a standard atmospheric pressure environment or an air environment, after injecting a preset volume of sealant into the sealing channel through the first opening, the method further includes obtaining the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component. The air pressure value of the second environment is adjusted according to one or more of the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component.

[0026] By injecting a preset volume of sealant into the sealing channel from the first opening, the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural parts, and the surface treatment method of the structural parts are obtained, and the air pressure value of the second environment is adjusted according to one or more of the above parameters. This can improve the accuracy of the air pressure value of the second environment and thereby improve the sealing efficiency.

[0027] In one possible implementation, before injecting a preset volume of sealant into the sealing channel through the first opening, the method further includes obtaining the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component. The first preset time is determined based on one or more of the following: the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component.

[0028] By obtaining the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural part, and the surface treatment method of the structural part before injecting a preset volume of sealant into the sealing channel from the first opening, and determining the first preset time based on one or more of the above parameters, the accuracy of the injection time of the structural part in the first environment can be improved to ensure the sealing of the sealing channel and improve the sealing efficiency.

[0029] In one possible implementation, before injecting a preset volume of sealant into the sealing channel through the first opening, the method further includes obtaining the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component. The preset volume of the sealant is determined based on one or more of the following: the volume of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, and the material of the structural component.

[0030] Before injecting a preset volume of sealant into the sealing channel through the first opening, the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component are obtained, and the preset volume of the sealant is determined based on one or more of these parameters. This can improve the accuracy of the sealant dosage in the sealing channel, thereby preventing sealant overflow. It can also prevent the problem of poor sealing effect caused by insufficient sealant, thereby ensuring the sealing performance of the sealing channel and improving sealing efficiency.

[0031] In a possible implementation, a size of the first opening is larger than a size of the second opening.

[0032] By setting the first opening larger than the second opening, when injecting sealant from the first opening into the sealing channel, it is easier to inject the sealant from the first opening into the sealing channel, thereby improving the sealing efficiency of the structural component. Since the second opening is away from the external surface of the structural component, setting the second opening larger will not affect the external surface of the structural component.

[0033] In a possible implementation, one of the first structural member and the second structural member is a display screen, the other of the first structural member and the second structural member is a middle frame of an electronic device, and the sealed channel is a gap between the display screen and the middle frame.

[0034] By setting one of the first structural member and the second structural member as a display screen and setting the other of the first structural member and the second structural member as the middle frame of the electronic device, the middle frame and the display screen can be sealed, thereby improving the waterproof performance of the electronic device using the structural member.

[0035] In one possible implementation, one of the first and second structural members is a flexible printed circuit board. The other of the first and second structural members is a middle frame or adapter of an electronic device, and the middle frame or adapter is provided with a through-hole for the flexible printed circuit board to pass through. The sealed channel is a gap between the flexible printed circuit board and the inner wall of the through-hole. Alternatively, the sealed channel is a gap between the flexible printed circuit board and the middle frame. Alternatively, the sealed channel is a gap between the middle frame or the adapter.

[0036] By setting one of the first structural member and the second structural member as a flexible circuit board and setting the other of the first structural member and the second structural member as a middle frame or an adapter, the perforations on the middle frame or the adapter and the flexible circuit board can be sealed, thereby improving the waterproof performance of the electronic device using the structural member.

[0037] In one possible implementation, one of the first and second structural members is a screw or bolt. The other of the first and second structural members is an adapter, which has a threaded hole for the screw or bolt to pass through. The sealed passage is a gap between the screw or bolt and the inner wall of the threaded hole.

[0038] By setting one of the first structural member and the second structural member as a screw or bolt and setting the other of the first structural member and the second structural member as an adapter, the threaded hole and the bolt or screw on the adapter can be sealed, thereby improving the waterproof performance of the electronic device using the structural member.

[0039] A second aspect of an embodiment of the present application provides an electronic device including a structural member, wherein the structural member includes a first structural member and a second structural member, wherein a sealed channel is defined between the first structural member and the second structural member. A sealant is provided in the sealed channel, and the sealant is sealed in the sealed channel using any of the aforementioned structural member sealing methods.

[0040] By sealing the sealant in the sealing channel of the structural component of the electronic device using the above-mentioned structural component sealing method, the sealing performance of the structural component can be improved, thereby enhancing the waterproof performance of the electronic device. In addition, the aesthetic appearance of the electronic device can be maintained.

[0041] In one possible implementation, one of the first structural member and the second structural member is a display screen of the electronic device. The other of the first structural member and the second structural member is a middle frame of the electronic device. The sealed channel is a gap between the display screen and the middle frame.

[0042] By arranging the first structural member and the second structural member on the display screen and the middle frame respectively, the sealing between the display screen and the middle frame can be improved, thereby improving the waterproof performance of the electronic device.

[0043] In one possible implementation, the display screen and the middle frame both have exterior surfaces, wherein one end of the sealed channel opens to extend between the exterior surfaces of the display screen and the middle frame, and the other end opens toward the interior of the electronic device.

[0044] By providing both the display screen and the middle frame with exterior surfaces, and extending one end of the sealing channel between the exterior surfaces of the display screen and the middle frame, with the other end opening toward the interior of the electronic device, when sealing the sealing channel, the end of the sealing channel facing the exterior surfaces of the display screen and the middle frame can be sealed, thereby ensuring the aesthetic appearance of the electronic device.

[0045] In one possible implementation, one of the first and second structural members is a flexible printed circuit board of the electronic device. The other of the first and second structural members is a middle frame or adapter of the electronic device, the middle frame or adapter having a through-hole for the flexible printed circuit board to pass through, and the sealed channel is a gap between the flexible printed circuit board and the inner wall of the through-hole. Alternatively, the sealed channel is a gap between the middle frame or the adapter.

[0046] By setting one of the first structural member and the second structural member as a flexible circuit board and setting the other of the first structural member and the second structural member as a middle frame or an adapter, the perforations on the middle frame or the adapter and the flexible circuit board can be sealed, thereby improving the waterproof performance of the electronic device.

[0047] In one possible implementation, one of the first and second structural members is a screw or bolt on the electronic device. The other of the first and second structural members is an adapter on the electronic device, the adapter having a threaded hole for the screw or bolt to pass through. The sealed passage is a gap between the screw or bolt and the inner wall of the threaded hole.

[0048] By setting one of the first structural member and the second structural member as a screw or bolt and setting the other of the first structural member and the second structural member as an adapter, the threaded hole and the bolt or screw on the adapter can be sealed, thereby improving the waterproof performance of the electronic device.

[0049] In a possible implementation, the sealing channel has a sealing end and a glue injection end, wherein the glue injection end is larger than the sealing end, and the glue injection end is located inside the electronic device.

[0050] By setting the injection end larger than the sealing end, the sealant can be injected into the sealing channel from the injection end, making it easier to do so, improving the sealing efficiency of the structural component. By locating the injection end inside the electronic device, the larger size of the injection end does not affect the appearance of the structural component. Furthermore, when the sealing end faces the exterior surface of the structural component, the aesthetic appearance of the electronic device is enhanced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0069] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0070] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and its other forms, such as the third person singular form "comprises" and the present participle form "comprising", are to be interpreted as open and inclusive, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example" or "some examples" are intended to indicate that the particular features, structures, materials or characteristics associated with the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the particular features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0071] In addition, in this application, directional terms such as "front" and "rear" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to changes in the orientation of the components in the drawings.

[0072] In the embodiments of this application, "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0073] In recent years, with the continuous improvement of people's material and cultural living standards, the types and functions of electronic products have become more and more numerous, and consumers have higher and higher requirements for the waterproof performance of electronic products. In order to meet the waterproof specifications of consumer electronic products, it is necessary to seal the through holes in electronic products.

[0074] It is understood that electronic products are electronic devices, which typically include multiple components. When assembling electronic devices, through-holes are often provided for connection. Connectors are placed in through-holes to connect two components, creating gaps between the connectors and the inner walls of the through-holes, as well as between adjacent components. If these gaps cannot be sealed, the electronic device's waterproof performance will be compromised, failing to meet consumer demand for electronic devices.

[0075] Typically, in order to seal a gap in an electronic device, a sealant may be injected into the gap to seal the gap on the electronic device.

[0076] For example, as shown in FIG1 , an electronic device includes a first component 20 and a second component 30, wherein a gap 40 is formed between the first component 20 and the second component 30. To ensure the sealing of the electronic device, a sealant 50 needs to be injected into the gap 40 of the electronic device. The sealant 50 can be injected directly at one end of the gap 40, relying on its own fluidity to flow into the gap 40, thereby sealing the gap 40.

[0077] Exemplarily, the gap 40 includes a glue injection end 41 and a non-glue injection end 42, wherein the end where the sealant is injected serves as the glue injection end 41. Exemplarily, the glue injection end 41 of the gap 40 faces the interior of the electronic device, and the non-glue injection end 42 of the gap 40 faces the exterior surface 44 of the electronic device.

[0078] It should be noted that the appearance surface of an electronic device refers to the outer surface of the electronic device. In other words, the surface of the electronic device that can be seen by the user when in use is the appearance surface. The appearance surface of a structural component refers to the side that faces the user when the first component 20 and the second component 30 are assembled into the electronic device. The appearance surface 44 of the first component 20 and the second component 30 refers to the side that faces the user when the first component 20 and the second component 30 are assembled into the electronic device. It is understood that when the first component 20 and the second component 30 are located in the electronic device, the appearance surface 44 can be any side of the first component 20 and the second component 30.

[0079] Continuing with FIG1 , when the viscosity of sealant 50 is low, the sealant 50 has good fluidity, which can easily lead to overflow and leakage, resulting in a poor aesthetic appearance of the electronic device. In some cases, the sealant 50 may even flow out of the gap 40, completely failing to provide any sealing effect.

[0080] As shown in FIG2 , when the viscosity of the sealant 50 is high, the fluidity of the sealant 50 itself is poor, and the sealant 50 cannot rely on its own fluidity to flow into the gap 40. In particular, when there is an irregular area in the gap 40, or the gap 40 is small in size, the sealant 50 accumulates at the injection end of the gap 40 and cannot seal the gap 40 at all.

[0081] As shown in FIG3 , in the following embodiment, glue can be injected at the glue injection end 41 of the gap 40, and negative pressure can be applied at the non-glue injection end 42 of the gap 40 to draw the sealant 50 into the gap 40, thereby sealing the gap 40. Although this allows the sealant 50 to flow into the irregular micro-gap 40, the negative pressure can cause bubbles to form within the sealant 50. In other words, this reduces the bubble removal performance of the sealant 50, resulting in bubbles remaining in the sealant 50 within the gap 40, making the seal unstable and prone to water leakage, resulting in poor waterproof performance of the electronic device.

[0082] In addition, applying negative pressure at one end of the gap 40 cannot solve the problem of glue overflow or leakage on the exterior surface 44 of the first component 20 and the second component 30, resulting in poor aesthetics of the exterior surface 44 of the electronic device.

[0083] Based on the above technical problems, embodiments of the present application provide a method for sealing a structural component and an electronic device. The method for sealing a structural component prevents glue overflow or leakage by sealing one end of a gap and injecting glue at the other end of the gap. By first injecting glue into the structural component in a first environment and then placing the structural component in a second environment, the pressure difference between the first and second environments is utilized to seal the remaining sealant or all of the sealant that has entered the sealing channel back into the sealing channel, ensuring that irregular shapes and micro-slits in the sealing channel can be effectively filled.

[0084] The sealing method of the structural component and the electronic device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0085] Figure 4 is a schematic diagram of a process for sealing a structural member according to an embodiment of the present application. Figure 5 is a schematic diagram of a structural member according to an embodiment of the present application. Figure 6 is a schematic diagram of a structural member according to an embodiment of the present application.

[0086] An embodiment of the present application provides a sealing method for a structural component. As shown in FIG4 , the sealing method may include the following steps.

[0087] S101. Provide a structural member, the structural member including a first structural member and a second structural member, a sealed channel between the first structural member and the second structural member, and the sealed channel including a first opening and a second opening.

[0088] S102: placing the structural component in a first environment, with the second opening in a sealed state.

[0089] S103 , injecting a preset volume of sealant into the sealing channel from the first opening. In the first environment, the sealant automatically flows toward the second opening.

[0090] S104 . After a first preset time, place the structural component in a second environment, where the pressure of the second environment is greater than the pressure of the first environment, so that the sealant is sealed and filled in the sealing channel under the pressure difference between the second environment and the first environment.

[0091] The structural component sealing method provided in the embodiments of the present application can prevent glue overflow or leakage after the sealing channel is sealed by sealing the second opening of the sealing channel, and can also control the amount of sealant used. By first placing the structural component in a first environment and then injecting a preset volume of sealant into the sealing channel through the first opening, the amount of sealant used can be controlled and the sealant can be injected into the sealing channel.

[0092] By placing the structural component in the second environment after the first preset time, part or all of the sealant can be injected into the sealing channel when the sealant is in the first environment.

[0093] By setting the pressure of the second environment to be greater than the pressure of the first environment, the pressure difference between the second environment and the first environment can be utilized to seal and fill the remaining sealant or all the sealant entering the sealing channel in the sealing channel, ensuring that the special-shaped and micro-gap positions in the sealing channel can be effectively filled.

[0094] In addition, the sealant is squeezed under positive pressure to fill the sealing channel, which can reduce the risk of bubbles in the sealant compared to filling by pumping negative pressure.

[0095] It should be noted that, for the sake of convenience, in the embodiment of the present application, the end of the sealing channel where glue is injected is referred to as the injection end, and in the embodiment of the present application, the first opening is the injection end. The end of the sealing channel where glue is not injected is referred to as the non-injection end, and in the embodiment of the present application, the second opening is the non-injection end.

[0096] The following is a detailed description of step S101.

[0097] As shown in FIG5 , the structural member 100 includes a first structural member 10 and a second structural member 11. A sealing channel 12 is defined between the first structural member 10 and the second structural member 11. The sealing channel 12 includes a first opening 121 and a second opening 122. The first opening 121 is the end for injection of glue into the sealing channel 12, and the second opening 122 is the end for non-injection of glue into the sealing channel 12.

[0098] It should be noted that in step S101, the first structural member 10 and the second structural member 11 in the structural member 100 are not further limited. For example, the structural member 100 may be a component of an electronic device. The following description will take the structural member 100 as an example of a component of an electronic device.

[0099] Illustratively, the electronic device may include a display screen, a middle frame, a flexible circuit board, an adapter, screws or bolts, etc.

[0100] In one possible implementation, one of the first structural member 10 and the second structural member 11 is a display screen of the electronic device, and the other of the first structural member 10 and the second structural member 11 is a middle frame of the electronic device. A sealing channel 12 is formed between the display screen and the middle frame, and the sealing channel 12 is a gap between the display screen and the middle frame.

[0101] By setting one of the first structural member 10 and the second structural member 11 as a display screen and setting the other of the first structural member 10 and the second structural member 11 as the middle frame of the electronic device, the middle frame and the display screen can be sealed, thereby improving the waterproof performance of the electronic device using the structural member 100.

[0102] In one possible implementation, one of the first structural member 10 and the second structural member 11 is a flexible printed circuit board. The other of the first structural member 10 and the second structural member 11 is a middle frame or adapter of an electronic device. The middle frame or adapter of the electronic device has a through-hole for the flexible printed circuit board to pass through. During assembly, the flexible printed circuit board can be inserted into the through-hole and connected to the middle frame or adapter. The sealing channel 12 can be a gap between the flexible printed circuit board and the inner wall of the through-hole.

[0103] Of course, in other embodiments, the connection relationship between the flexible circuit board and the middle frame or adapter can also be other forms. For example, one of the first structural member 10 and the second structural member 11 is a flexible circuit board, and the other of the first structural member 10 and the second structural member 11 is a middle frame or adapter of the electronic device. A sealed channel 12 is formed between the flexible circuit board and the middle frame or adapter, wherein the sealed channel 12 is a gap between the flexible circuit board and the middle frame or adapter.

[0104] By setting one of the first structural member 10 and the second structural member 11 as a flexible circuit board and setting the other of the first structural member 10 and the second structural member 11 as a middle frame or an adapter, the perforations on the middle frame or the adapter and the flexible circuit board can be sealed, thereby improving the waterproof performance of the electronic device using the structural member 100.

[0105] In one possible implementation, one of the first structural member 10 and the second structural member 11 is a screw or bolt. The other of the first structural member 10 and the second structural member 11 is an adapter having a threaded hole for the screw or bolt to pass through. The sealing passage 12 is a gap between the screw or bolt and the inner wall of the threaded hole.

[0106] By setting one of the first structural member 10 and the second structural member 11 as a screw or bolt and setting the other of the first structural member 10 and the second structural member 11 as an adapter, the threaded hole and the bolt or screw on the adapter can be sealed, thereby improving the waterproof performance of the electronic device using the structural member 100.

[0107] It should be noted that the adapter can be a rotating shaft structure, or other adapters for connecting two components. In the embodiment of the present application, the specific structure of the adapter is not further limited.

[0108] In addition, in other embodiments, the first structural member 10 and the second structural member 11 include but are not limited to the above-mentioned structural members. In other embodiments, the first structural member 10 and the second structural member 11 can also be other components on the electronic device, as long as the above-mentioned sealing channel 12 is formed between the first structural member 10 and the second structural member 11.

[0109] In a possible implementation, providing the structural member 100 includes forming an exterior surface 15 on at least one of the first structural member 10 and the second structural member 11 . The second opening 122 extends to the exterior surface 15 .

[0110] Exemplarily, both the first structural member 10 and the second structural member 11 are formed with an exterior surface 15, such as a display screen and a middle frame of an electronic device. Alternatively, one of the first structural member 10 and the second structural member 11 is formed with an exterior surface 15, such as a middle frame and a flexible circuit board of an electronic device.

[0111] It should be noted that the exterior surface 15 refers to the outer surface of the electronic device. In other words, the surface of the electronic device that can be seen by the user during use is the exterior surface 15. In other words, at least one of the first structural member 10 and the second structural member 11 is the outer surface of the electronic device.

[0112] By forming an appearance surface 15 on at least one of the first structural member 10 and the second structural member 11 and extending the second opening 122 to the appearance surface 15, since the second opening 122 is in a sealed state before glue injection, it can be ensured that the appearance surface 15 of the structural member 100 has no glue leakage or overflow problems, and the appearance surface 15 can be ensured to be flat and beautiful.

[0113] It should be noted that in the embodiment of the present application, the shape of the sealing channel 12 is not further limited. It is understandable that the shape of the sealing channel 12 is related to the shape of the first structural member 10 and the second structural member 11. For example, as shown in FIG5 , when the partial structure of the first structural member 10 and the second structural member 11 forming the sealing channel 12 is a flat plane, the sealing channel 12 can be a channel with a flat inner wall. As shown in FIG6 , when the partial structure of the first structural member 10 and the second structural member 11 forming the sealing channel 12 has a bend or an irregular shape, the sealing channel 12 is an internally uneven channel, that is, the sealing channel 12 has an irregular shape.

[0114] In a possible implementation, as shown in FIG6 , the size of the first opening 121 of the sealing channel 12 may be set to be larger than the size of the second opening 122 .

[0115] By setting the size of the first opening 121 larger than the second opening 122, when the sealant 13 is injected from the first opening 121 into the sealing channel 12, it can be easily injected from the first opening 121 into the sealing channel 12, thereby improving the sealing efficiency of the structural component 100. Because the second opening 122 faces away from the exterior surface 15 of the structural component 100, setting the size of the second opening 122 larger will not affect the exterior surface 15 of the structural component 100.

[0116] In some embodiments, step S102 may specifically include first placing the structural member 100 in the first environment and then sealing the second opening 122. Of course, in other embodiments, step S102 may also specifically include first sealing the second opening 122 and then placing the structural member 100, with the second opening 122 sealed, in the first environment. In the present embodiment, the order of sealing the second opening 122 and placing the structural member 100 in the first environment is not further limited. After step S102, the structural member 100 is shown in FIG. 7 , with the second opening 122 of the sealed channel 12 of the structural member 100 in a sealed state.

[0117] The sealing method of the second opening 122 is described below.

[0118] In a possible implementation, before or after placing the structural component 100 in the first environment, the method may further include providing a sealing structure 14 at the second opening 122 for sealing the second opening 122 , so that the second opening 122 is in a sealed state.

[0119] By providing a sealing structure 14 at the second opening 122 for sealing the second opening 122, the second opening 122 is kept sealed, thereby preventing glue leakage or overflow at the second opening 122. Furthermore, the outer side of the second opening 122 is kept relatively flat, ensuring that the exterior surface 15 of the structural component 100 is neat and aesthetically pleasing when the second opening 122 faces the exterior surface 15.

[0120] It should be noted that different sealing structures 14 can be selected to seal the second opening 122 in different scenarios. For example, when the non-injection end of the sealing channel 12 is irregularly shaped, the sealing structure 14 can be provided with a peelable sealant 13. The second opening 122 is sealed by sticking the peelable sealant 13 on the second opening 122. Since the shape of the peelable sealant 13 can change with the shape of the second opening 122, the sealing effect at the second opening 122 can be improved. In addition, the peelable sealant 13 is easy to remove. After the sealing channel 12 is sealed, the sealing structure 14 can be removed, which can reduce the difficulty of removing the sealing structure 14, thereby reducing the sealing cost of the structural member 100.

[0121] When the non-glue injection end of the sealing channel 12 is of regular shape, the sealing structure 14 may be configured to include a clamp, wherein a portion of the clamp is disposed at the second opening 122 and is sealed to the second opening 122 .

[0122] For example, as shown in FIG8 , the second opening 122 of the sealing channel 12 is flush with the first structural member 10 and the second structural member 11, and the clamp includes a sealing portion 141 and a fixing portion 142, wherein the structural member 100 is fixedly connected to the fixing portion 142 of the clamp, and the sealing portion 141 of the clamp is located at the second opening 122. By clamping the sealing portion 141 in a direction close to the second opening 122 (F in the figure represents the clamping force), the second opening 122 can be sealed. Of course, in other embodiments, the second opening 122 can also be sealed by using the clamp through other operations. In the embodiment of the present application, the specific operation of using the clamp to seal the second opening 122 is not further limited. In addition, the specific structure of the clamp is not further limited.

[0123] By configuring the sealing structure 14 to include a clamp, the second opening 122 can be sealed by simply placing the structural component 100 on the clamp through certain operations. This can simplify the procedure for sealing the second opening 122 of the sealing channel 12, thereby improving the sealing efficiency of the structural component 100 and facilitating industrial production.

[0124] The following is a detailed description of step S103.

[0125] Injecting a preset volume of the sealant 13 into the sealing channel 12 through the first opening 121 may specifically include obtaining a preset volume of the sealant 13 and then injecting the preset volume of the sealant 13 into the first opening 121 .

[0126] As shown in FIG. 9 , obtaining the preset volume of the sealant 13 may include the following steps.

[0127] S201. Obtain the volume and shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component.

[0128] S202. Determine a preset volume of the sealant based on one or more of the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component.

[0129] It should be noted that since the preset volume of the sealant is related to the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment of the structural component, the preset volume of the sealant can be obtained by obtaining the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment of the structural component, and then accurately determining the preset volume of the sealant based on these parameters. This can accurately control the amount of sealant, thereby ensuring the stability of the seal and saving costs.

[0130] Exemplarily, the preset volume of the sealant can be determined based on one of the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component. The preset volume of the sealant can also be determined based on all of the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component. The preset volume of the sealant can also be determined based on the volume of the sealing channel, the viscosity of the sealant, and the curing method of the sealant. In the embodiment of the present application, the number of parameters for determining the preset volume of the sealant is not further limited.

[0131] Of course, in some other embodiments, the preset volume of the sealant may be determined by obtaining other parameters.

[0132] Exemplarily, the method for obtaining the preset volume of sealant may also include obtaining one or more of the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural part, and the surface treatment method of the structural part.

[0133] The preset volume of the sealant is determined based on one or more data information including the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural part, and the surface treatment method of the structural part.

[0134] In the embodiment of the present application, the specific method for obtaining the preset volume of the sealant is not further limited.

[0135] It should be noted that the preset volume of sealant should be determined before injecting the preset volume of sealant into the sealing channel from the first opening. By obtaining the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component before injecting the preset volume of sealant into the sealing channel from the first opening, and determining the preset volume of sealant based on one or more of these parameters, the accuracy of the amount of sealant used in the sealing channel can be improved, which can prevent overflow of sealant. It can also prevent the problem of poor sealing effect caused by insufficient amount of sealant. This ensures the sealing of the sealing channel 12 and improves the sealing efficiency.

[0136] Of course, in some other embodiments, the preset volume of the sealant can also be obtained after the structural member is provided. In the implementation of this application, the time for obtaining the preset volume of the sealant is not further limited.

[0137] In step S103 , when injecting glue into the first opening 121 of the sealing channel 12 , the structural component 100 is shown in FIG. 10 , and the sealant 13 automatically flows toward the second opening 122 due to its own fluidity.

[0138] Next, step S104 will be described.

[0139] Placing the structural component 100 in the second environment after the first preset time specifically includes obtaining the first preset time, and then placing the structural component 100 in the second environment after the first preset time has passed.

[0140] As shown in FIG11 , obtaining the first preset time specifically includes the following steps.

[0141] S301. Obtain the volume and shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component.

[0142] S302. Determine a first preset time based on one or more of the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component.

[0143] It should be noted that since the first preset time is related to the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component, the first preset time can be obtained more accurately by obtaining the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component. This can ensure that within the first preset time, most or all of the sealant enters the sealing channel, ensuring that the structural component is placed in the second environment and the sealant can be compacted in the sealing channel, thereby completely sealing the sealing channel.

[0144] Exemplarily, the first preset time can be determined based on one of the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component. The first preset time can also be determined based on all of the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component. The first preset time can also be determined based on the volume of the sealing channel, the viscosity of the sealant, and the curing method of the sealant. In the embodiment of the present application, the number of parameters for determining the first preset time is not further limited.

[0145] Of course, in some other embodiments, the first preset time may also be determined by obtaining other parameters.

[0146] Exemplarily, the method for obtaining the first preset time may also include obtaining one or more of the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural part, and the surface treatment method of the structural part.

[0147] The first preset time is determined based on one or more data information obtained, including the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural part, and the surface treatment method of the structural part.

[0148] In the embodiment of the present application, the specific method for obtaining the first preset time is not further limited.

[0149] It should be noted that the first preset time should be determined before a preset volume of sealant is injected into the sealing channel through the first opening. By obtaining the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component before injecting the preset volume of sealant into the sealing channel through the first opening, and determining the first preset time based on one or more of these parameters, the accuracy of the injection time of the structural component in the first environment can be improved, thereby ensuring the sealing of the sealing channel and improving the sealing efficiency.

[0150] In step S104 , after the structural component 100 is placed in the second environment, the structural component 100 is as shown in FIG. 12 , and the sealant 13 is sealed and filled in the sealing channel 12 under the pressure difference between the second environment and the first environment.

[0151] In some other embodiments, as shown in FIG. 13 , after placing the structural member 100 in the second environment, the step further includes: S105 , removing the sealing structure from the second opening after a second preset time.

[0152] After step S105, the structural member 100 is shown in Figure 14 . The sealing channel 12 of the structural member 100 is sealed, and the sealing structure 14 at the second opening 122 is removed. The first structural member 10 and the second structural member 11 are sealed. Furthermore, the second opening 122 is relatively flat, with no glue overflow or leakage.

[0153] After the structural member 100 is placed in the second environment, the sealing mechanism is removed from the second opening 122 after a second preset time, so that there are no redundant parts on the structural member 100, thereby simplifying the structure of the structural member 100, and when the second opening 122 faces the appearance surface 15 of the structural member 100, the aesthetics of the structural member 100 can be improved.

[0154] The second preset time can be determined in the same manner as the first preset time. Of course, in other embodiments, the second preset time can also be set to the time required for the sealant 13 to completely solidify. This ensures that the sealant 13 is completely solidified and that the sealant 13's sealing properties are not compromised when the sealing structure 14 is removed.

[0155] The pressures of the first environment and the second environment are described below.

[0156] In one possible implementation, the first environment is a negative pressure environment. Since the pressure of the second environment is greater than that of the first environment, in one possible implementation, the second environment can be set to a standard atmospheric pressure environment or an air environment. In this way, a pressure difference can be formed between the second environment and the first environment, thereby ensuring that the irregular shapes and micro-gap positions in the sealing channel 12 can be effectively filled. In addition, the sealant 13 is squeezed by positive pressure to fill the sealing channel 12, which can reduce the risk of bubbles in the sealant 13 compared to filling by pumping negative pressure. In addition, it is only necessary to provide a negative pressure environment, and after a first preset time, the first environment is depressurized. The operation is simple, and the steps of sealing the structure 14 part 100 can be simplified. In addition, a negative pressure environment is easy to provide, and an air environment is also easy to provide, so this can reduce the cost of sealing the structural part 100.

[0157] It should be noted that the specific air pressure of the air environment is related to the temperature of the environment, altitude, etc. In the embodiments of the present application, the air environment refers to the air environment in daily life, which can also be called the external environment, that is, the natural environment, so the air pressure in the air environment is close to a standard atmospheric pressure.

[0158] As shown in FIG. 15 , when the first environment is a negative pressure environment, the method for obtaining the negative pressure value of the first environment may include:

[0159] S401. Obtain the volume and shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component.

[0160] S402. Adjust the negative pressure value of the first environment according to one or more of the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural part, and the surface treatment method of the structural part.

[0161] It should be noted that, since the negative pressure value of the first environment is related to the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component, the negative pressure value of the first environment can be obtained more accurately by obtaining the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component. This can ensure that in the first environment, the sealant has good bubble removal performance when entering the sealing channel, thereby ensuring the sealing stability of the sealing channel.

[0162] Exemplarily, the negative pressure value of the first environment can be determined based on one of the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural member, and the surface treatment method of the structural member. The negative pressure value of the first environment can also be determined jointly based on all of the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural member, and the surface treatment method of the structural member. The negative pressure value of the first environment can also be determined jointly by the volume of the sealing channel, the viscosity of the sealant, and the curing method of the sealant. In the embodiment of the present application, the number of parameters for determining the negative pressure value of the first environment is not further limited.

[0163] Of course, in some other embodiments, the negative pressure value of the first environment may be determined by obtaining other parameters.

[0164] Exemplarily, the method for obtaining the negative pressure value of the first environment may also include obtaining one or more of the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural part, and the surface treatment method of the structural part.

[0165] The negative pressure value of the first environment is determined based on one or more data information including the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural part, and the surface treatment method of the structural part.

[0166] In the embodiment of the present application, the specific method for obtaining the negative pressure value of the first environment is not further limited.

[0167] It should be noted that when the first environment is a negative pressure environment, the negative pressure value of the first environment can be obtained before a preset volume of sealant 13 is injected into the sealing channel 12 through the first opening 121. By obtaining the volume of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure, and the material of the structural component before injecting the preset volume of sealant 13 into the sealing channel 12 through the first opening 121, and adjusting the negative pressure value of the first environment based on one or more of these parameters, the accuracy of the negative pressure value of the first environment can be improved, thereby enhancing the sealing efficiency.

[0168] In some other embodiments, the first environment may also be set to a standard atmospheric pressure environment or an air environment.

[0169] When the first environment is set to a standard atmospheric pressure environment or an air environment, the second environment can be set to an environment with a higher air pressure than the standard atmospheric pressure environment or the air environment. This creates a pressure differential between the second environment and the first environment, thereby ensuring that irregular shapes and micro-slits within the sealing channel 12 can be effectively filled. Furthermore, the positive pressure squeezes the sealant 13 to fill the sealing channel 12, which reduces the risk of bubbles in the sealant 13 compared to filling with negative pressure. Furthermore, a standard atmospheric pressure environment or an air environment is easy to obtain, and obtaining the second environment only requires pressurizing the first environment, which is convenient and reduces the cost of sealing the structural component 100.

[0170] As shown in FIG. 16 , when the first environment is set to a standard atmospheric pressure environment or an air environment, the method for obtaining the second environment pressure value may include:

[0171] S501. Obtain the volume and shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural component, and the surface treatment method of the structural component.

[0172] S502. Adjust the air pressure value of the second environment according to one or more of the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural part, and the surface treatment method of the structural part.

[0173] It should be noted that since the air pressure value of the second environment is related to the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural parts, and the surface treatment method of the structural parts, the air pressure value of the second environment is obtained by obtaining the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural parts, and the surface treatment method of the structural parts, and is relatively accurate based on these parameters. It can be ensured that under the air pressure of the second environment, the sealant 13 can be compacted in the sealing channel 12, thereby completely sealing the sealing channel 12.

[0174] Exemplarily, the air pressure value of the second environment can be determined based on one of the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural member, and the surface treatment method of the structural member. The air pressure value of the second environment can also be jointly determined based on all of the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural member, and the surface treatment method of the structural member. The air pressure value of the second environment can also be jointly determined by the viscosity of the sealant and the curing method of the sealant. In the embodiment of the present application, the number of parameters for determining the air pressure value of the second environment is not further limited.

[0175] Of course, in some other embodiments, the air pressure value of the second environment may be determined by obtaining other parameters.

[0176] Exemplarily, the method for obtaining the air pressure value of the second environment may also include obtaining one or more of the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural part, and the surface treatment method of the structural part.

[0177] The air pressure value of the second environment is determined based on one or more data information including the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural part, and the surface treatment method of the structural part.

[0178] In the embodiment of the present application, the specific method for obtaining the air pressure value of the second environment is not further limited.

[0179] It should be noted that when the first environment is a standard atmospheric pressure environment or an air environment, the air pressure value of the second environment can be obtained after a preset volume of sealant 13 is injected into the sealing channel 12 through the first opening 121. By obtaining the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure, the material of the structural component, and the surface treatment method of the structural component after injecting the preset volume of sealant 13 into the sealing channel 12 through the first opening 121, and adjusting the air pressure value of the second environment based on one or more of these parameters, the accuracy of the air pressure value of the second environment can be improved, thereby improving the sealing efficiency.

[0180] It should be noted that, in the embodiment of the present application, the acquisition time of the preset volume of the sealant, the first preset time, the air pressure value of the first environment, and the air pressure value of the second environment are not further limited. For example, all the required parameters, such as the preset volume of the sealant, the first preset time, the air pressure value of the first environment, and the air pressure value of the second environment, can be obtained in the first step of the entire sealing method as described in the steps of the above embodiment, and then the sealing step can be performed. In the embodiment of the present application, the acquisition time of the preset volume of the sealant, the first preset time, the air pressure value of the first environment, the air pressure value of the second environment, and the second preset time are not further limited.

[0181] It should be noted that whether the first environment is set as a negative pressure environment and the second environment is set as an air environment, or the first environment is set as an air environment and the second environment is set to an environment with a pressure greater than the air environment, one of the environments can be an air environment during the injection process, and the air environment is easy to obtain, so this can reduce the process steps of injection and thus reduce the injection cost.

[0182] It should be noted that the volume and shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure, the material of the structural component, and the surface treatment of the structural component will affect parameters such as the injection time, injection volume, and injection pressure of the structural component. Furthermore, parameters such as the injection time, injection volume, and injection pressure will affect the preset volume of the sealant, the first preset time, the air pressure value of the first environment, and the air pressure value of the second environment.

[0183] Therefore, by determining the preset volume of the sealant, the first preset time, the air pressure value of the first environment, and the air pressure value of the second environment through one or more of the volume of the sealing channel, the shape of the sealing channel, the viscosity of the sealant, the curing method of the sealant, the bubble removal performance of the sealant under positive pressure extrusion, the material of the structural part, and the surface treatment method of the structural part, the accuracy of the glue injection can be improved, the waste of sealant can be reduced, and the problem of incomplete sealing due to insufficient amount of sealant can be prevented.

[0184] It should be noted that in the above-mentioned embodiments, the material of the structural member includes the material of the first structural member and the material of the second structural member. The surface treatment method of the structural member includes the surface treatment method of the first structural member and the surface treatment method of the second structural member. During the process of the sealant flowing from the first opening to the second opening of the sealing channel, some sealant will penetrate into the structural member from the surface of the structural member, and some sealant will adhere to the surface of the structural member, which will affect the preset volume of the sealant, the first preset time, the air pressure value of the first environment, and the air pressure value of the second environment.

[0185] However, the material and surface treatment of the structural component will affect the fluidity and wettability of the sealant on the surface of the structural component. Among them, wettability can be understood as the ability of the sealant to penetrate from the surface of the structural component into the interior of the structural component. Good wettability means that most of the sealant can penetrate from the surface of the structural component into the structural component. Poor wettability means that a small part of the sealant can penetrate from the surface of the structural component into the interior of the structural component. In other words, the material and surface treatment of the structural component can affect the preset volume of the sealant, the first preset time, the air pressure value of the first environment, and the air pressure value of the second environment.

[0186] For example, when the material of the structural part is plastic and metal, the fluidity and wettability of the sealant on the surface of the structural part are different. Therefore, by determining the preset volume of the sealant, the first preset time, the air pressure value of the first environment, and the air pressure value of the second environment according to the material of the structural part, the accuracy of the preset volume of the sealant, the first preset time, the air pressure value of the first environment, and the air pressure value of the second environment can be improved, which can avoid wasting sealant, save time, and prevent the problem of incomplete sealing due to insufficient sealant usage.

[0187] Similarly, the surface treatment methods of structural parts are different, and the fluidity and wettability of sealant on the surface of structural parts are different. Therefore, by determining the preset volume of sealant, the first preset time, the air pressure value of the first environment, and the air pressure value of the second environment according to the material of the structural parts, the accuracy of glue injection can be improved, the waste of sealant can be reduced, and the problem of incomplete sealing due to insufficient sealant can be prevented.

[0188] For example, the surface treatment methods of the structural parts may include electroplating, painting, chemical oxidation, thermal spraying, etc. In the embodiments of the present application, the surface treatment methods of the structural parts are not further limited.

[0189] It should be noted that the volume and shape of the sealing channel can affect the preset volume of the sealant, the first preset time, the air pressure value of the first environment, and the air pressure value of the second environment. For example, if the same sealing effect is to be achieved, the preset volume of the sealant, the first preset time, the air pressure value of the first environment, and the air pressure value of the second environment of the sealing channel with a larger volume and the sealing channel with a smaller volume need to be set differently. For example, the preset volume of the sealant of the sealing channel with a larger volume should be larger than the preset volume of the sealant of the sealing channel with a smaller volume, etc.

[0190] In addition, the shape of the sealing channel can be a circular gap, a circular gap with a bend in the middle (as shown in Figure 6), or a narrow gap. The shape of the sealing channel will affect the time it takes for the sealant to enter the sealing channel. The longer the sealing time, the longer the sealant will flow on the surface of the sealing channel. The longer the injection time, the more sealant will penetrate into the inner wall of the structural part. Therefore, the shape of the sealing channel will also affect the amount of sealant and the injection time.

[0191] In addition, the viscosity of the sealant, the curing method of the sealant, and the bubble removal performance of the sealant under positive pressure extrusion will all affect the preset volume of the sealant, the first preset time, the air pressure value of the first environment, and the air pressure value of the second environment. For example, if the viscosity of the sealant is relatively large, the first preset time for injection may be longer. Moreover, the viscosity of the sealant, the curing method of the sealant, and the bubble removal performance of the sealant under positive pressure extrusion are related to the type of sealant, so these parameters can be determined according to the type of sealant. In the embodiments of the present application, the specific method for obtaining the preset volume, the first preset time, the air pressure value of the first environment, and the air pressure value of the second environment is no longer further limited.

[0192] An embodiment of the present application also provides an electronic device, which may include but is not limited to a mobile phone, a tablet computer, a laptop computer, an ultra-mobile personal computer (UMPC), a handheld computer, a touch-screen TV, a walkie-talkie, a netbook, a POS machine, a personal digital assistant (PDA), a wearable device, a virtual reality device, or other fixed or mobile terminal with a camera lens.

[0193] In an embodiment of the present application, the electronic device may include a structural member 100, which may include a first structural member 10 and a second structural member 11. A sealing channel 12 is defined between the first structural member 10 and the second structural member 11 (see FIG5 ). Sealant 13 is provided within sealing channel 12, and sealant 13 is sealed within sealing channel 12 using the structural member sealing method provided in any of the above embodiments, as shown in FIG14 .

[0194] By sealing the sealant in the sealing channel of the structural component of the electronic device using the above-mentioned structural component sealing method, the sealing performance of the structural component can be improved, thereby enhancing the waterproof performance of the electronic device. In addition, the aesthetic appearance of the electronic device can be maintained.

[0195] For example, as shown in FIG17 , the electronic device 200 is described as a mobile phone. The electronic device 200 may include a display screen 210, a middle frame 220, a flexible printed circuit board 230, a housing 240, a battery 250, an adapter, screws or bolts, etc. During assembly, the display screen 210 may be positioned opposite the housing 240, the middle frame 220 may be positioned between the housing 240 and the display screen 210, and the battery 250 and the flexible printed circuit board 230 may be positioned between the middle frame 220 and the housing 240.

[0196] In one possible implementation, one of the first structural member 10 and the second structural member 11 is a display screen of an electronic device. The other of the first structural member 10 and the second structural member 11 is a midframe of the electronic device. The sealing channel 12 is a gap between the display screen and the midframe (not shown).

[0197] By arranging the first structural member 10 and the second structural member 11 on the display screen and the middle frame respectively, the sealing between the display screen and the middle frame can be improved, thereby improving the waterproof performance of the electronic device.

[0198] In a possible implementation, the display screen and the middle frame both have exterior surfaces, wherein one end opening of the sealing channel 12 extends between the exterior surfaces of the display screen and the middle frame, and the other end opening faces into the electronic device.

[0199] By providing both the display screen and the middle frame with exterior surfaces, and extending one end of the sealing channel 12 between the exterior surfaces of the display screen and the middle frame, with the other end opening toward the interior of the electronic device, when sealing the sealing channel 12, the end facing the exterior surfaces of the display screen and the middle frame can be sealed, thereby ensuring the aesthetic appearance of the electronic device.

[0200] In one possible implementation, one of the first structural member 10 and the second structural member 11 is a flexible printed circuit board of an electronic device. The other of the first structural member 10 and the second structural member 11 is a middle frame or an adapter of the electronic device. The middle frame or the adapter is provided with a through-hole for the flexible printed circuit board to pass through. The sealing channel 12 is a gap between the flexible printed circuit board and the inner wall of the through-hole.

[0201] Of course, in other embodiments, the connection relationship between the flexible circuit board and the middle frame or adapter can also be other forms. For example, one of the first structural member 10 and the second structural member 11 is a flexible circuit board, and the other of the first structural member 10 and the second structural member 11 is a middle frame or adapter of the electronic device. A sealed channel 12 is formed between the flexible circuit board and the middle frame or adapter, wherein the sealed channel 12 is a gap between the flexible circuit board and the middle frame or adapter.

[0202] By setting one of the first structural member 10 and the second structural member 11 as a flexible circuit board and setting the other of the first structural member 10 and the second structural member 11 as a middle frame or an adapter, the perforations on the middle frame or the adapter and the flexible circuit board can be sealed, thereby improving the waterproof performance of the electronic device using the structural member.

[0203] In one possible implementation, one of the first structural member 10 and the second structural member 11 is a screw or bolt. The other of the first structural member 10 and the second structural member 11 is an adapter having a threaded hole for the screw or bolt to pass through. The sealing passage 12 is a gap between the screw or bolt and the inner wall of the threaded hole.

[0204] By setting one of the first structural member 10 and the second structural member 11 as a screw or bolt and setting the other of the first structural member 10 and the second structural member 11 as an adapter, the threaded hole and the bolt or screw on the adapter can be sealed, thereby improving the waterproof performance of the electronic device using the structural member.

[0205] It should be noted that the adapter can be a rotating shaft structure, or other adapters for connecting two components. In the embodiment of the present application, the specific structure of the adapter is not further limited.

[0206] In addition, in other embodiments, the first structural member 10 and the second structural member 11 may also be other components of the electronic device, as long as the above-mentioned sealing channel 12 is formed between the first structural member 10 and the second structural member 11 .

[0207] In one possible implementation, the sealed channel 12 has a sealing end and a glue injection end. The glue injection end is larger than the sealing end (see FIG6 ), and the glue injection end is located inside the electronic device. It should be noted that the sealing end in this embodiment corresponds to the non-glue injection end in the above-described embodiment.

[0208] By setting the injection end larger than the sealing end, the sealant 13 can be easily injected into the sealing channel 12 from the injection end, thereby improving the sealing efficiency of the structural component. By locating the injection end inside the electronic device, the larger injection end does not affect the appearance of the structural component. Furthermore, when the sealing end faces the exterior surface of the structural component, the aesthetic appearance of the electronic device can be improved.

[0209] It should be noted that the first structural member 10 and the second structural member 11 include, but are not limited to, the aforementioned display screen and middle frame, the flexible circuit board and middle frame, as well as adapters, screws, bolts, and adapters. In other embodiments, the first structural member 10 and the second structural member 11 may also have other structures. In the present embodiment, the specific structure of the first structural member 10 and the second structural member 11 is not further limited. As long as there is a sealed passage between the first structural member 10 and the second structural member 11 that needs to be sealed, it is protected within the scope of the present embodiment.
