[0025] Figure 7 This is an exploded view of an electronic device according to an exemplary embodiment. Detailed Implementation

[0026] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0027] In related technologies, by adding a potting hole through the middle frame, adhesive is injected into the potting hole from the back of the middle frame. The adhesive can flow along the potting hole to the space between the middle frame and the screen, and seal the gap between the screen and the middle frame, thereby achieving a waterproof and sealed design for electronic devices.

[0028] However, the glue-filling structure requires the entire device to maintain a certain thickness so that the glue-filling port can accurately fill the glue-filling hole, which makes it difficult for electronic devices to be further designed to be thinner and lighter.

[0029] To address the aforementioned technical problems, embodiments of this disclosure provide a housing assembly and an electronic device. The housing assembly includes: a mid-frame, including a first surface; a groove, including a first opening disposed on the first surface and a second opening opposite to the first opening; a functional component, at least a portion of which is disposed within the groove through the second opening; and a sealing component for closing the first opening.

[0030] This disclosure achieves a good waterproof sealing effect by placing at least a portion of the functional components in the groove and sealing the first opening of the groove with a sealing component, thereby reducing the stacking thickness of the functional components and the middle frame.

[0031] It is understood that the housing components involved in this disclosure can be used in any of the terminals listed below.

[0032] It is understood that the terminal involved in this disclosure may also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., and is a device that provides voice and / or data connectivity to a user. For example, a terminal may be a handheld device with wireless connectivity, an in-vehicle device, etc. Currently, some examples of terminals include: smartphones (Mobile Phones), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptops, tablets, wearable devices, or in-vehicle devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device may also be an in-vehicle device. It should be understood that the embodiments of this disclosure do not limit the specific technology or specific device form adopted by the terminal.

[0033] Figure 1 This is a schematic diagram illustrating the structure of an electronic device with a hidden screen assembly according to an exemplary embodiment. Figure 2 yes Figure 1 A cross-sectional view formed along section line A.

[0034] In some embodiments, such as Figure 1 and Figure 2 As shown, the housing assembly may include: a middle frame 100, a groove, a functional component 30, and a closing assembly.

[0035] The middle frame 100 may be a skeleton structure for providing mounting and support for other components, and the middle frame 100 may include a first surface.

[0036] The groove can be disposed in the middle frame 100, and the groove can include a first opening disposed on the first surface and a second opening opposite to the first opening. At least a portion of the functional component 30 can be disposed in the groove through the second opening. The groove can provide a larger installation space for the functional component 30, thereby reducing the stacking thickness between the functional component 30 and the middle frame 100, and thus reducing the overall thickness of the housing assembly.

[0037] The sealing component can be disposed on the first surface and close the first opening to prevent liquid and water vapor from entering the interior of the housing component from the first opening.

[0038] This disclosure achieves a good waterproof sealing effect by placing at least a portion of the functional component 30 in the groove and sealing the first opening of the groove with a sealing component, thereby reducing the stacking thickness of the functional component and the middle frame 100.

[0039] In some embodiments, the closure assembly may include a closure member and a first sealing assembly.

[0040] A closure is disposed on the first surface and closes the first opening of the groove. For example, the closure may be a sheet-like structural member.

[0041] The first sealing component can be disposed between the first surface and the closure member, and seal the gap between the first surface and the closure member to prevent liquid or moisture from entering the interior of the housing assembly from the gap between the closure member and the first surface, thereby improving the waterproof performance of the housing assembly.

[0042] In some embodiments, such as Figure 1 and Figure 2 As shown, functional component 30 can be a port assembly, and the closure can include a first closure 11 that closes the first opening of the first through hole 10. The first sealing assembly can include a first seal 12, which is disposed between the first seal 12 and the first surface. The thickness of the first closure 11 is 0.10 mm to 0.06 mm. For example, the thickness of the first closure 11 can be 0.08 mm, thereby achieving a reduction of 0.22 mm in the thickness of the housing assembly.

[0043] By setting the thickness of the first closure 11 within the aforementioned thickness range, the space occupied by the first closure 11 in the thickness direction of the housing assembly can be reduced, thereby reducing the installation space required for the housing assembly in the thickness direction. This facilitates the lightweight design of the housing assembly and increases the competitiveness of the product.

[0044] In some embodiments, the functional component 30 may be a USB interface assembly, which may include a housing. The housing may be provided with a silicone component, which may be elastically deformed and interference-fitted with the middle frame 100 to achieve a waterproof sealing effect between the functional component 30 and the middle frame 100.

[0045] Furthermore, at least a portion of the silicone component can be disposed within the first through-hole 10. For example, the silicone component can be interference-fitted with the inner wall of the first through-hole 10 to achieve a waterproof sealing effect between the functional component 30 and the middle frame 100. The first through-hole 10 provides additional mounting space for the silicone component of the USB interface assembly, thereby reducing the stacking thickness of the functional component 30 and the middle frame 100, thereby reducing the mounting space required in the thickness direction of the housing assembly, and thus reducing the thickness of the housing assembly.

[0046] In some embodiments, the first closure 11 and the functional component 30 may be spaced 0.2 mm to 0.1 mm apart in the thickness direction of the housing assembly. For example, the first closure 11 and the functional component 30 may be spaced 0.15 mm apart in the thickness direction of the housing assembly. By setting the spacing between the first closure 11 and the functional component 30 within the above-mentioned range, the distance between the first closure 11 and the functional component 30 can be reduced, avoiding wasting installation space in the thickness direction, while also preventing direct collision between the functional component 30 and the first closure 11, thus preventing damage to the first closure 11 due to collision and improving the reliability of the first closure 11.

[0047] In some embodiments, the first closure 11 is a glass fiber component. Glass fiber components have the advantages of good toughness, high strength and low density, and are easy to process into smaller thicknesses, thereby reducing the thickness of the first closure 11 while maintaining its strength and improving its reliability.

[0048] Figure 3 yes Figure 1 A cross-sectional view formed along section line C. Figure 4 This is a schematic diagram of the structure of an electronic device that conceals a screen assembly and a second enclosure, according to an exemplary embodiment.

[0049] In some embodiments, such as Figure 1 , Figure 3 and Figure 4As shown, the functional component 30 can be a battery, and the tank can also include a battery compartment 20, which can be used to accommodate the battery. The closure can include a second closure 21, which can close the first opening of the battery compartment 20. The first sealing assembly can include a second seal 22, which can be disposed between the second closure 21 and the first surface, and seal the gap between the second closure 21 and the first surface to prevent liquid or moisture from entering the housing assembly from the gap between the second closure 21 and the first surface.

[0050] In some embodiments, the second closure 21 can be a silicon carbide plate, which has the advantages of high strength and low density, and is easy to process into a smaller thickness, thereby reducing the thickness of the second closure 21. Furthermore, the strength of the second closure 21 can improve the overall strength of the battery compartment 20, enabling the battery compartment 20 to achieve sufficient structural strength with a smaller structural thickness, reducing the likelihood of deformation of the battery compartment 20 after the battery is installed.

[0051] In some embodiments, the first seal 12 and the second seal 22 can be moisture-curing reactive polyurethane hot melt adhesive, which can be applied between the seal and the first surface by a dispensing process.

[0052] Figure 5 yes Figure 1 A cross-sectional view formed along section line B.

[0053] In some embodiments, such as Figure 5 As shown, the housing assembly may include a gas channel 40, the first end of which may be disposed on the first surface and facing the first closure member 11, and the second end of which may be connected to the outside.

[0054] During airtightness testing, the sealing performance of the first closure 11 can be checked by injecting gas into the gas channel 40. When the sealing performance of the first closure 11 is good, gas will not leak out from the gap between the first closure 11 and the first surface, thus proving that the first closure 11 has good sealing performance and can meet the waterproof design requirements of the housing assembly.

[0055] In some embodiments, the middle frame 100 may include a second surface on which a speaker is disposed. A second opening of the first through-hole 10 may be disposed on the second surface, and a gas channel 40 may be connected through the first through-hole 10, allowing the speaker to communicate with the outside world through the first through-hole 10 and the gas channel 40. Since the speaker compresses its front or rear cavity during operation, allowing the speaker to communicate with the outside world through the first through-hole 10 and the gas channel 40 maintains communication between the front or rear cavity and the outside, preventing abnormal noise caused by gas compression in the front or rear cavity and improving the speaker's audio performance.

[0056] Figure 6 This is a schematic diagram of the structure of an electronic device that conceals a screen assembly and a first enclosure, according to an exemplary embodiment.

[0057] In some embodiments, such as Figure 6 As shown, the middle frame 100 may also be provided with a second through hole 52, which can penetrate the middle frame 100 and communicate with the gas channel 40, so that the speaker can communicate with the outside through the second through hole 52 and the gas channel 40. By increasing the number of through holes, the speed of gas exchange through the gas channel 40 of the speaker can be increased, thereby ensuring the performance stability of the speaker.

[0058] In some embodiments, such as Figure 5 and Figure 6 As shown, the housing assembly may include a waterproof and breathable membrane 60. The waterproof and breathable membrane 60 may be disposed on the first surface and seal the first end of the gas channel 40.

[0059] Since the gas channel 40 needs to be connected to the outside world and exchange gas, a waterproof and breathable membrane 60 is provided in the gas channel 40 to allow gas to flow through the gas channel 40 while preventing liquid from entering the interior of the housing assembly from the gas channel 40, thereby improving the waterproof performance of the housing assembly.

[0060] In some embodiments, functional component 30 may include one or more of electrical connectors, batteries, screws, and clips. For example, functional component 30 may be a USB interface assembly or a battery.

[0061] Based on the same concept, embodiments of this disclosure also provide an electronic device.

[0062] The electronic device can be a laptop computer, desktop computer, mobile phone, digital broadcasting terminal, messaging device, game console, tablet device, medical device, fitness equipment, personal digital assistant, translator, and wearable devices such as watches and bracelets, and can be any electronic device with a housing component. In the following description, a mobile phone is used as an example, but this disclosure is not limited to this.

[0063] In some embodiments, such as Figure 2 As shown, the electronic device may include a screen assembly 300 and a housing assembly, with the screen assembly 300 disposed on the first side of the middle frame 100. The screen assembly 300 can be used to display image information.

[0064] In some embodiments, such as Figure 1 As shown, the electronic device may include a receiving space 200 and a third seal 70.

[0065] The housing assembly can be enclosed with the screen assembly 300 to form a receiving space 200, which can be used to receive electronic components of the electronic device. For example, the receiving space 200 can be used to receive functional devices of the screen assembly 300.

[0066] The third seal 70 can be disposed between the first surface and the screen assembly 300, or the third seal 70 can be disposed between the sealing assembly and the screen assembly 300, so that the third seal 70 surrounds the receiving space 200 and seals the receiving space 200.

[0067] The third sealing element 70 is a liquid adhesive.

[0068] Since the side of the screen assembly 300 facing the middle frame 100 has functional components such as flexible circuit boards and connectors, the side of the screen assembly 300 that cooperates with the middle frame 100 has many steps. These steps may cooperate with the steps of the middle frame 100 or form gaps with the side edges of the middle frame 100. To avoid the impact of the step structure and gaps on the sealing effect of the third seal 70, the third seal 70 is configured as a liquid adhesive. This allows the third seal 70 to flow and match the step structure and gap structure, thereby ensuring the sealing effect at the step structure and gaps. This improves the sealing effect of the third seal 70 on the screen assembly 300 and the first side, as well as on the accommodating space 200.

[0069] In some embodiments, after the closure is disposed on the middle frame 100, the edge of the closure and the middle frame 100 will form a step portion, and the edge of the closure will form a gap with the side of the middle frame 100 or the side of the groove disposed on the middle frame 100. In order to avoid the impact of the step portion and the gap on the sealing effect of the third seal 70, the third seal 70 is configured as a liquid adhesive, so that the third seal 70 can match the step portion and gap structure through its own flow, thereby ensuring the sealing effect at the step and gap, thereby improving the sealing effect of the third seal 70 on the screen assembly 300 and the first surface, as well as the sealing effect of the third seal 70 on the accommodating space 200, realizing sealing in the case of multi-step structure, and enabling electronic devices to meet the IPX8 waterproof sealing requirements.

[0070] Figure 7 This is an exploded view of an electronic device according to an exemplary embodiment.

[0071] In some embodiments, such as Figure 1 and Figure 7 As shown, the electronic device may also include a fourth seal, which, for example, may include a first sub-seal 81 and a second sub-seal 82.

[0072] A fourth seal can be disposed between the first surface and the screen assembly 300, so that the fourth seal can seal the receiving space 200 together with the third seal 70. The fourth seal can be a seal with a certain degree of hardness. The fourth seal can be used to support the screen assembly 300 before the third seal 70 solidifies, so as to maintain the distance between the screen assembly 300 and the first surface, prevent the screen assembly 300 from squeezing the third seal 70 and causing the third seal 70 to overflow, and improve the process stability of the seal.

[0073] In some embodiments, the electronic device can be a foldable electronic device. Existing potting solutions require opening long potting channels on the mid-frame 100, which is insufficient for the thickness requirements of the opening process in foldable electronic devices due to limited thickness space. Furthermore, when there are many stepped and gap structures, the potting adhesive does not provide a good seal for these structures. By using a third sealing element 70 for dispensing and a fourth sealing element for support, effective front-side dispensing sealing is achieved, improving the reliability of the individual unit's airtightness and reducing the possibility of poor airtightness of the housing assembly due to poor dispensing.

[0074] In some embodiments, the fourth seal may be a foam adhesive, which has good resistance to compression deformation and can effectively support the screen assembly 300 before the third seal 70 solidifies, so as to maintain the gap between the screen assembly 300 and the first surface.

[0075] In some embodiments, such as Figure 1 and Figure 7 As shown, the electronic device may include a screen assembly 300, a main screen adhesive foam (first sub-seal 81), a sealant (third seal 70), a sealing support foam (second sub-seal 82), a fiberglass sheet (first closure 11), PUR adhesive (first seal 12), a vent valve (waterproof and breathable membrane 60), a mid-frame 100, a battery compartment support silicon carbide plate (second closure 21), a battery (not shown in the figure), and a small board (not shown in the figure).

[0076] like Figure 1 and Figure 7 As shown, the battery compartment supporting silicon carbide plate and fiberglass sheet can be installed on the mid-frame by dispensing adhesive. There are gaps between the edges of the battery compartment supporting silicon carbide plate and fiberglass sheet and their mounting points on the mid-frame 100, forming a stepped structure. After dispensing sealant onto the mid-frame 100, the screen assembly 300 is placed on the first surface of the mid-frame 100 and the sealant is pressed down. The liquid sealant fills the gaps and stepped structure, achieving a complete seal around the accommodating space 200. Furthermore, the main screen sealing foam and sealing support foam, acting as a support structure, prevent the screen assembly from dislodging the sealant and prevent adhesive overflow, while also providing a double-layer seal.

[0077] The functional component 30 can be a USB port assembly. The functional component 30 can include sealing silicone. The middle frame 100 above the USB sealing silicone can be provided with a first through hole 10. At least a portion of the USB sealing silicone can be disposed in the first through hole 10. The spacing between the USB sealing silicone and the fiberglass sheet in the thickness direction is only 0.15mm. In order to reduce the thickness of the electronic device, the thickness of the fiberglass sheet pair can be set to 0.08mm.

[0078] The fiberglass sheet can be sealed to the mid-frame 100 using PUR adhesive. A cavity can be formed between the fiberglass sheet, the mid-frame, and the PUR adhesive. The first end of the gas channel 40 can communicate with this cavity, and the second end of the gas channel 40 can communicate with the outside atmosphere. A vent valve can be installed in this cavity and seal the first end of the gas channel 40. When performing airtightness testing on the mid-frame unit, outside atmosphere can enter the cavity composed of the fiberglass sheet, mid-frame 100, and PUR adhesive through the vent valve, enabling the airtightness testing of the PUR adhesive and reducing overall airtightness leakage caused by poor individual adhesive application. Through the above configuration, the sealing effect of the screen assembly and the stepped structure and gaps of the mid-frame 100 can be improved with a smaller electronic device thickness, enabling the electronic device to meet the IPX8 sealing requirements.

[0079] The first through hole 10 can connect the cavity on the second side of the middle frame 100 with the cavity composed of the fiberglass sheet, the middle frame and PUR adhesive, so that the outside atmosphere can communicate with the cavity on the second side of the middle frame 100 through the gas channel 40, the cavity and the first through hole 10. The cavity on the second side of the middle frame 100 can be equipped with a speaker. The speaker can communicate with the outside atmosphere through the above-mentioned channel, thereby maintaining the air pressure balance of the speaker, avoiding noise, and improving the audio quality of the speaker.

[0080] This embodiment of the disclosure achieves a good waterproof sealing effect by placing at least a portion of the functional component 30 in the groove and sealing the first opening of the groove with a sealing component, thereby reducing the stacking thickness of the functional component and the middle frame 100.
