Description

Technical Field

[0001] This disclosure relates to the field of electronic equipment technology, and in particular to an electronic device and a method for assembling the same. Background Technology

[0002] With the development of technology, people have increasingly higher requirements for the waterproof performance of mobile phones and other electronic devices.

[0003] In related technologies, electronic devices include a housing, an earpiece, a display assembly, and a seal. The housing includes a connected mid-frame, a mid-plate, and an earpiece trim. The mid-plate has a through-hole and a mounting notch, to which the earpiece trim is fixed. The earpiece is connected to the mid-plate and faces the through-hole. The display assembly is located on the side of the mid-plate away from the earpiece and has a gap with the mid-plate. It includes a connected structural reinforcement and a display portion. The structural reinforcement is connected to the earpiece trim, and the display portion and the earpiece trim are spaced apart to form a safety gap. A sealant is connected to the structural reinforcement, the earpiece trim, and the mid-frame, forming a sound outlet channel between the sealant and the mid-frame, mid-plate, and earpiece trim.

[0004] Sealant is often quite hard. If it's directly connected to the display and the frame, a collision with the electronic device that causes the frame to deform will cause the sealant to directly compress the display, potentially damaging it. Placing the earpiece trim on the outside of the display protects it and prevents this from happening. However, the earpiece trim needs a certain thickness to ensure its strength, which inevitably increases the thickness of the electronic device in that location. Summary of the Invention

[0005] This disclosure provides an electronic device and its assembly method, which can solve the aforementioned technical problems existing in related technologies. The technical solution is as follows:

[0006] In a first aspect, an electronic device is provided, the electronic device comprising a housing, a handset, a display assembly, and a sealing structure;

[0007] The housing includes a connected middle frame and a middle plate, the middle plate having through holes;

[0008] The earpiece is connected to the middle plate and is opposite to the through hole;

[0009] The display component is located on the side of the middle plate away from the earpiece and is connected to the middle plate. It includes a connected structural reinforcement portion and a display portion. The structural reinforcement portion is connected to the middle frame and a gap is formed between it and the middle frame.

[0010] The sealing structure includes a first part and a second part connected together. The first part is connected to the middle plate and the display part respectively. The second part is connected to the middle frame, the display part and the structural reinforcement part respectively, and is elastic. A sound outlet channel is formed between the sealing structure, the display part, the middle frame and the middle plate. The sound outlet channel is connected to the gap and the through hole.

[0011] In one possible implementation, the second part is in a compressed state and can still be compressed.

[0012] In one possible implementation, the middle frame has a mounting groove, and the second portion is fixed within the mounting groove.

[0013] In one possible implementation, the depth of the mounting groove is greater than the minimum compression thickness of the second portion.

[0014] In one possible implementation, the sealing structure includes a first seal and a second seal connected together, a portion of the first seal forming the first part, and another portion cooperating with the second seal to form the second part, the second seal being located within the mounting groove.

[0015] In one possible implementation, the second seal is a hollow sealing gasket.

[0016] In one possible implementation, the sealing structure is a sealing foam.

[0017] In one possible implementation, the surface of the sealing structure has a waterproof double-sided adhesive.

[0018] In one possible implementation, the electronic device further includes a waterproof layer located between the first portion and the display portion, and serving to separate the display portion from the sound output channel.

[0019] In a second aspect, an assembly method is provided for the electronic device provided in the first aspect and its possible implementations, the assembly method comprising:

[0020] The second seal is fixed in the mounting groove;

[0021] The first seal is fixed to the middle plate, and the first seal is connected to the second seal, and the first seal compresses the second seal.

[0022] Fix the earpiece to the middle plate and align it with the through hole;

[0023] The display portion is connected to the first sealing element, the structural reinforcement portion is connected to the middle frame, and the sound outlet channel is formed between the sealing structure, the display portion, the middle frame, and the middle plate.

[0024] The beneficial effects of the technical solution provided in this disclosure include at least the following:

[0025] In this disclosure, the display portion is connected to the mid-frame via a second part. Because the second part is elastic, it is compressed when the mid-frame deforms due to a collision with the electronic device, thus preventing the sealing structure from crushing and damaging the display portion. Therefore, this disclosure eliminates the need for an earpiece decorative piece between the mid-frame and the display portion, reducing the possibility of the sealing structure crushing and damaging the display portion. Furthermore, by reducing the thickness occupied by the earpiece decorative piece in the thickness direction of the electronic device, the thickness of the electronic device at the earpiece location can be reduced.

[0044] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] In related technologies, such as Figure 7As shown, the electronic device includes a housing 01, an earpiece 02, a display assembly 03, and sealant 04. The housing 01 includes a connected mid-frame 011, a mid-plate 012, and an earpiece trim 013. The mid-plate 012 has a through-hole 0121 and a mounting notch 0122, to which the earpiece trim 013 is fixed. The earpiece 02 is connected to the mid-plate 012 and faces the through-hole 0121 (and forms a seal against the through-hole 0121 to prevent water from entering the electronic device through the through-hole 0121). The display assembly 03 is located on the side of the mid-plate 012 away from the earpiece 02 and has a gap with the mid-plate 012. It includes a connected structural reinforcement 031 and a display portion 032. The structural reinforcement 031 is connected to the earpiece trim 013, and the display portion 032 and the earpiece trim 013 are spaced apart to form a safety gap 0131. Figures 7 to 8 As shown, the sealant 04 is connected to the structural reinforcement part 031, the earpiece decoration part 013, and the middle frame 011, and forms a sound outlet channel 014 between the sealant 04 and the middle frame 011, the middle plate 012, and the earpiece decoration part 013.

[0047] Among them, the sealant 04 is often quite hard. If the sealant 04 is directly connected to the display part 032 and the middle frame 011, when the electronic device is hit and the middle frame 011 is deformed, the sealant 04 will directly squeeze the display part 032, thereby causing damage to the display part 032. By placing the earpiece decorative part 013 on the outside of the display part 032, the display part 032 can be protected, thereby avoiding this situation.

[0048] However, the earpiece decorative part 013 needs a certain thickness to ensure its strength, which will inevitably result in a larger thickness of the electronic device in this position.

[0049] This disclosure provides an electronic device, such as... Figure 1 As shown, the electronic device includes a housing 1, a handset 2, a display assembly 3, and a sealing structure 4. The housing 1 includes a connected mid-frame 11 and a mid-plate 12, the mid-plate 12 having a through hole 121. The handset 2 is connected to the mid-plate 12 and faces the through hole 121. The display assembly 3 is located on the side of the mid-plate 12 away from the handset 2 and is connected to the mid-plate 12. It includes a connected structural reinforcement 31 and a display portion 32. The structural reinforcement 31 is connected to the mid-frame 11, and a gap 13 is formed between it and the mid-frame 11. Figure 2 As shown, the sealing structure 4 includes a first part 401 and a second part 402 connected together. The first part 401 is connected to the middle plate 12 and the display part 32 respectively. The second part 402 is connected to the middle frame 11, the display part 32 and the structural reinforcement part 31 respectively, and is elastic. A sound outlet channel 14 is formed between the sealing structure 4, the display part 32, the middle frame 11 and the middle plate 12. The sound outlet channel 14 is connected to the gap 13 and the through hole 121.

[0050] The display portion 32 is connected to the middle frame 11 via the second portion 402. Because the second portion 402 is elastic, it is compressed when the middle frame 11 deforms due to a collision with the electronic device, thus preventing the sealing structure 4 from crushing and damaging the display portion 32. Therefore, in the electronic device provided by this embodiment, it is unnecessary to provide an earpiece decorative piece between the middle frame 11 and the display portion 32, thereby reducing the possibility of the sealing structure 4 crushing and damaging the display portion 32. Furthermore, the thickness occupied by the earpiece decorative piece is reduced in the thickness direction of the electronic device, thereby reducing the thickness of the electronic device at the earpiece 2 position.

[0051] The electronic devices involved in this disclosure may also be referred to as terminals, mobile terminals, terminal devices, user equipment (UE), etc. For example, a terminal device may be a smartphone, tablet computer, laptop computer, wearable device (e.g., smartwatch), or it may be a digital camera, SLR camera / mirrorless camera, gimbal camera, action camera, drone, or other professional shooting equipment. It should be understood that this disclosure does not specifically limit the specific technology or device form used in the terminal device. In the description of the above embodiments, a mobile phone is used as an example, but this disclosure is not limited thereto.

[0052] This disclosure does not limit the material and forming method of the housing 1. For example, the middle frame 11 and the middle plate 12 are both made of metal and are integrally formed.

[0053] The earpiece 2 is connected to the middle plate 12 by a sealing adhesive (such as hot melt adhesive) to form a seal at the edge of the through hole 121. This reduces the possibility of liquids such as water entering the sound outlet channel 14 through the gap 13 and then entering the electronic device through the through hole 121, which could damage the electronic device.

[0054] like Figure 2 As shown, the middle frame 11 has an adhesive-coated step. The structural reinforcement 31 of the display component 3 can be, for example, but not limited to, tempered glass. The tempered glass is fixed to the adhesive-coated step by adhesive to achieve a fixed connection between the display component 3 and the middle frame 11. The adhesive has a notch at the gap 13 to avoid the adhesive blocking the sound emitted by the earpiece 2, thereby ensuring the volume at the gap 13.

[0055] There is a notch at the edge where the structural reinforcement part 31 of the display component 3 is connected to the middle frame 11. This notch is used to form a gap 13 between the component and the middle frame 11 to allow sound to pass through.

[0056] The display portion 32 of the display component 3 has a multi-layer structure. The display portion 32 includes at least a light-emitting layer and a metal base plate. The light-emitting layer is connected to the metal base plate, and the metal base plate is connected to the first part 401 of the sealing structure 4.

[0057] like Figure 3 As shown, the middle frame 11 is located in the part of the sound outlet channel 14 and has a relief groove. The relief groove is used to increase the volume of the sound outlet channel 14 so that sound can flow in the sound outlet channel 14.

[0058] The sound output channel 14 can be divided into a portion located between the display portion 32 and the middle plate 12, and a portion between the display portion 32 and the middle frame 11; both portions are flat, rectangular-column shaped. Figure 3 As shown, the projection of the sound output channel 14 onto the middle plate 12 can be divided into two rectangular shapes. The rectangular shape on the left corresponds to the portion of the sound output channel 14 located between the display portion 32 and the middle plate 12, and the rectangular shape on the right corresponds to the portion of the sound output channel 14 located between the display portion 32 and the middle frame 11. One side of the rectangular shape on the left is attached to one side of the rectangular shape on the right, and the length of the side of the rectangular shape on the left is shorter than the length of the side of the rectangular shape on the right.

[0059] The electronic devices provided in the embodiments of this disclosure will be further described below with reference to some examples.

[0060] In some examples, the second part 402 is compressed and can still be compressed.

[0061] The second part 402 is in a compressed state. Since the second part 402 is elastic, it has a tendency to return to its original shape. Therefore, the second part 402 will squeeze the middle frame 11 and the display part 32 respectively, and fit tightly with the middle frame 11 and the display part 32. This ensures that the second part 402 is stably fixed between the middle frame 11 and the display part 32. Thus, the sealing effect of the second part 402 can effectively reduce the possibility of liquid entering the electronic device from the edge of the sound outlet channel 14.

[0062] Since the second part 402 can still be compressed, when the electronic device is collided and the middle frame 11 is deformed, the second part 402 can continue to be compressed and deformed, thereby preventing the display part 32 from being damaged by the compression of the second part 402.

[0063] The second part 402 is in a compressed state, mainly referring to the compressed state in the spacing direction between the display component 3 and the middle frame 11. Optionally, the second part 402 can also be in a compressed state in the spacing direction between the display component 3 and the middle plate 12 to ensure that the second part 402 is stably fitted with the structural reinforcement part 31, so as to ensure the sealing effect of the second part 402 in the connection with the structural reinforcement part 31.

[0064] The first part 401 is also in a compressed state, which allows the first part 401 to fit tightly with the middle plate 12 and the display part 32, thereby effectively preventing liquids such as water from entering the electronic device from between the first part 401 and the middle plate 12 or the display part 32.

[0065] In some examples, such as Figure 3 or Figure 4 As shown, the middle frame 11 has a mounting groove 111, and the second part 402 is fixed in the mounting groove 111.

[0066] If the side of the middle frame 11 is a flat surface, and the second part 402 has only one side in contact with the middle frame 11, if the middle frame 11 is deformed, a small gap may appear between the second part 402 and the middle frame 11, which will lead to a decrease in the sealing effect.

[0067] In contrast, in this embodiment of the present disclosure, an installation groove 111 is formed on the middle frame 11, and the second part 402 is fixed in the installation groove 111. This allows multiple surfaces of the second part 402 to be in contact with multiple groove walls of the installation groove 111, thereby effectively reducing the possibility of a small gap between the second part 402 and the middle frame 11 when the middle frame 11 deforms, thus effectively ensuring the sealing effect of the sealing structure 4.

[0068] In some examples, the depth of the mounting slot 111 is greater than the minimum compression thickness of the second part 402.

[0069] In this way, when the second part 402 is compressed to the slot position of the mounting groove 111, the second part 402 has not yet reached the compression limit, thereby minimizing the damage to the display part 32 caused by the second part 402.

[0070] In some examples, such as Figure 3 or Figure 4 As shown, the sealing structure 4 includes a first sealing member 41 and a second sealing member 42 connected together. A part of the first sealing member 41 forms a first part 401, and another part cooperates with the second sealing member 42 to form a second part 402. The second sealing member 42 is located in the mounting groove 111.

[0071] In this way, when assembling electronic equipment, the second seal 42 can be fixed in the mounting groove 111 first, then compressed, and then the first seal 41 can be fixed to the middle plate 12, connecting the first seal 41 and the second seal 42. This facilitates the installation of the sealing structure 4. Furthermore, setting the sealing structure 4 as a split structure avoids excessive local deformation of a single seal, which could lead to damage to the seal.

[0072] In some examples, such as Figure 5 As shown, the second sealing element 42 is a sealing gasket, which is hollow.

[0073] When the middle frame 11 deforms, the sealing gasket is hollow and can collapse into the hollow part, thereby absorbing the energy of the middle frame 11 during the impact process, thus preventing the second part 402 from directly squeezing the display part 32 and causing damage to the display part 32.

[0074] like Figure 5 As shown, when the second seal 42 is a sealing gasket, the sealing gasket may include a connected main body 421 and a protrusion 422. The protrusion 422 is located on the side of the main body 421 near the second seal 42 and protrudes relative to the main body 421. The main body 421 is partially hollow to accommodate the protrusion 422 when it is compressed. The portions of the two opposite groove walls of the mounting groove 111 are recessed in a direction away from proportionality to accommodate the main body 421. This allows the sealing gasket to be stably installed within the mounting groove 111, ensuring the sealing effect of the sealing structure 4.

[0075] In some examples, such as Figure 4 As shown, sealing structure 4 is sealing foam.

[0076] The elasticity and lightweight nature of sealing foam make it easy to install and use, and its excellent waterproof and sealing properties make it an ideal waterproof sealing material. Furthermore, due to its porous structure, sealing foam can evenly distribute high-velocity physical pressure (impact energy), achieving excellent cushioning.

[0077] Sealing foam can be made of, for example, but not limited to, polyurethane, polyethylene, or polyvinyl chloride.

[0078] In some examples, such as Figure 6 As shown, the surface of the sealing structure 4 has waterproof double-sided adhesive 4a.

[0079] This allows for relatively convenient installation between the sealing structure 4 and the display component 3, the middle frame 11, and the housing 1.

[0080] The following section describes the case where the sealing structure 4 is a sealing foam. Waterproof double-sided adhesive 4a is located on the surface of the sealing foam, and a protective film 6 is attached to the outside of the waterproof double-sided adhesive 4a to protect it. When installing the sealing structure 4 and the housing 1, the protective film 6 on one side of the sealing foam can be peeled off to connect the sealing foam to the housing 1. When installing the display component 3, the protective film 6 on the other side of the sealing foam can be peeled off to connect the sealing foam to the display component 3. The edge of the protective film 6 protrudes beyond the edge of the sealing foam to facilitate peeling off the protective film 6.

[0081] Waterproof double-sided tape 4a can be, for example, but not limited to, acrylic adhesive.

[0082] In some examples, such as Figure 1 or Figure 2 As shown, the electronic device also includes a waterproof layer 5, which is located between the first part 401 and the display part 32 and serves to separate the display part 32 from the sound output channel 14.

[0083] The side of the display component 32 closest to the middle plate 12 is often made of metal. Contact between this metal structure and the liquid entering the sound outlet channel 14 can cause corrosion, leading to damage to the metal structure and consequently, the display component 3. By applying a waterproof layer 5 between the first part 401 and the display component 32, the liquid entering the sound outlet channel 14 can be prevented from contacting the side of the display component 32 closest to the middle plate 12, thus protecting the display component 3.

[0084] The waterproof layer 5 can be, for example, but not limited to, a Mylar layer.

[0085] Based on the same concept, this disclosure also provides an assembly method for the electronic device provided above, the assembly method comprising:

[0086] The second seal 42 is fixed in the mounting groove 111;

[0087] The first seal 41 is fixed to the middle plate 12, and the first seal 41 is connected to the second seal 42, and the first seal 41 compresses the second seal 42.

[0088] Fix the earpiece 2 to the middle plate 12 and align it with the through hole 121;

[0089] The display portion 32 is connected to the first seal 41, the structural reinforcement portion 31 is connected to the middle frame 11, and a sound outlet channel 14 is formed between the sealing structure 4, the display portion 32, the middle frame 11 and the middle plate 12.

[0090] Using this assembly method, the display part 32 is connected to the middle frame 11 by forming a second part 402 through the first seal 41 and the second seal 42. Since the second part 402 is elastic, when the electronic device is hit and the middle frame 11 is deformed, the second part 402 will be compressed, thereby preventing the sealing structure 4 from squeezing and damaging the display part 32.

[0091] Furthermore, in this embodiment of the present disclosure, when assembling electronic devices, the second sealing member 42 can be fixed in the mounting groove 111 first, then the second sealing member 42 can be compressed, and then the first sealing member 41 can be fixed in the middle plate 12 and the first sealing member 41 can be connected to the second sealing member 42, which can facilitate the installation of the sealing structure 4.

[0092] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this disclosure. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0093] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of this disclosure. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0094] In the description of this disclosure, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing this disclosure and simplifying the description. Unless otherwise stated, these directional terms 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, and therefore should not be construed as a limitation on the scope of protection of this disclosure; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.
