electronic devices
[0001] This application claims priority to Chinese Patent Application No. 202520210476.1, filed on February 10, 2025, entitled "Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of electronic equipment technology, and more particularly to an electronic device. Background Technology
[0003] Electronic devices use Type-C connectors (a type of Universal Serial Bus (USB) connector) for charging and data transmission. To prevent damage to internal electronic components, a waterproof design is required where the Type-C connector is located. However, current waterproof designs occupy significant layout space, making it difficult to meet the miniaturization requirements of electronic devices.
[0004] Utility Model Content
[0005] Some embodiments of this application provide an electronic device that can meet the waterproof requirements of connector assemblies, while not occupying a large layout space, which is conducive to miniaturization design. The following is a description of this application.
[0006] In a first aspect, embodiments of this application provide an electronic device comprising a back shell, a frame, a connector assembly, a pressure block, an elastic seal, and a sealing membrane. The frame surrounds the back shell circumferentially, forming a receiving cavity together with the back shell. A first through-hole is provided on the frame, communicating between the receiving cavity and the outside of the electronic device. The connector assembly includes a connector, a portion of which is located in the first through-hole, and another portion of which is located in the receiving cavity. The pressure block presses the connector assembly onto the back shell. The pressure block includes a second through-hole extending along the thickness direction of the electronic device, and the orthographic projection of the other portion of the connector on the pressure block at least partially overlaps with the second through-hole. The elastic seal provides a sealing connection between the pressure block and the connector assembly, between the pressure block and the frame, and between the connector assembly and the back shell, with the portion sealing between the pressure block and the connector assembly having an orthographic projection on the pressure block that does not overlap with the second through-hole. The sealing membrane is disposed on the side of the second through-hole facing away from the connector assembly and blocks the second through-hole.
[0007] In the aforementioned electronic devices, the sealing film can replace a portion of the elastic seal, or in other words, a portion of the thickness of the elastic seal is replaced by the thickness of the sealing film. Compared to the elastic seal, the sealing film has a smaller thickness. This effectively saves layout space for various components in the thickness direction of the electronic device, thus meeting the design requirements for thinner and lighter electronic devices.
[0008] In some embodiments, the connector assembly further includes a circuit board located within a receiving cavity and connected to the connector. The connector can be electrically connected to other electronic components (e.g., a motherboard) within the electronic device via the circuit board to enable signal transmission.
[0009] In some embodiments, the pressure block includes a first part, a second part, and a third part connected in sequence. The first part is pressed onto the connector, the third part is pressed onto the circuit board, and along the thickness direction of the electronic device, the distance between the first part and the display screen of the electronic device is greater than the distance between the third part and the display screen. A second through hole is formed on the second part.
[0010] According to an embodiment of this application, along the thickness direction of the electronic device, the first portion is closer to the display screen than the third portion. It is understood that, to achieve the connection between the first and third portions, the second portion is inclined relative to both the first and third portions. Therefore, at the second portion, the distance between the pressure block and the display screen gradually decreases. By opening the second through-hole on the second portion, the layout space of the second portion of the pressure block in the thickness direction of the electronic device can be effectively saved, thereby allowing the pressure block to avoid obstructing the display screen.
[0011] In some embodiments, the clamping block includes a first surface, and the connector includes a second surface. The first surface and the second surface are disposed opposite to each other along the thickness direction of the electronic device and abut against each other.
[0012] In this way, the clamping force of the clamping block can be effectively transferred from the first surface to the second surface, thereby providing better clamping force to the connector and making the connector installation more stable.
[0013] In some implementations, the connector includes a housing and a tongue, with the housing covering the outside of the tongue, and the circuit board is a printed circuit board. This allows for lower cost and wider applicability of the connector assembly.
[0014] In some embodiments, the resilient seal includes a first seal, a second seal, and a third seal, wherein the first seal is disposed between the pressure block and the connector assembly, the second seal is disposed between the pressure block and the frame, and the third seal is disposed between the connector assembly and the back cover.
[0015] After the pressure block compresses the connector assembly, the first, second, and third seals of the elastic seal are all under compression, which can fully fill the installation gap between the pressure block and the connector assembly, the installation gap between the pressure block and the frame, and the installation gap between the back shell and the connector assembly, ultimately achieving a reliable seal.
[0016] In some implementations, the orthographic projection of the third seal on the back cover does not overlap with the orthographic projection of another portion of the connector on the back cover. This allows the third seal to avoid the connector, saving layout space in the thickness direction of the electronic device and further contributing to the achievement of thinner and lighter design requirements.
[0017] In some implementations, the resilient seal is an integral structure, which can improve the sealing effect of the resilient seal.
[0018] In some implementations, the thickness of the sealing film is less than or equal to 0.1 mm, for example, 0.1 mm, 0.09 mm, 0.08 mm, 0.07 mm, etc. This allows the sealing film to be thin enough to meet the thinning requirements of electronic devices.
[0019] In some embodiments, the sealing film is made of polyethylene terephthalate or metal.
[0020] In some embodiments, the material of the briquette is powder metallurgy material or die casting material.
[0021] According to the embodiments of this application, when the material of the briquette is powder metallurgy material, the briquette can be formed by metal powder injection molding, thereby increasing the production efficiency and reducing the manufacturing cost. When the material of the briquette is die casting material, the briquette is a die casting. This further reduces production costs and makes it easier to form briquettes of various shapes to meet the needs of different application scenarios. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.
[0036] This application provides an electronic device having a connector for charging and data transmission. It is understood that the electronic device provided in this application can be, for example, a tablet, a mobile phone (e.g., a foldable phone, a candybar phone), a laptop computer, an ultra-mobile personal computer (UMPC), a handheld computer, a touchscreen TV, a walkie-talkie, a netbook, a personal digital assistant (PDA), a wearable device, a virtual reality device, a smart vehicle, a smart robot, or industrial equipment, etc., and this application does not impose specific limitations on this. Furthermore, it is understood that the connector can be, for example, a Type-C connector, a Type-A connector, or other types of USB connectors, and this application does not impose specific limitations on this. For ease of explanation, the following description uses a tablet as the electronic device and a Type-C connector as an example.
[0037] Figure 1 illustrates an exemplary structure of the plate 1 in an embodiment of this application. In the figures, the X direction represents the length direction of the plate 1, the Y direction represents the width direction of the plate 1, and the Z direction represents the thickness direction of the plate 1. The X, Y, and Z directions are perpendicular to each other. Referring to Figure 1, the dimensions of the plate 1 in both the length and width directions are greater than the dimensions of the plate 1 in the thickness direction. That is, the plate 1 has the smallest dimension in its thickness direction. In this application, the thickness of each component refers to the dimension of each component along the Z direction, which will not be elaborated further below.
[0038] It is understood that the perpendicularity in this application is not absolute perpendicularity. Approximate perpendicularity due to processing and assembly errors (e.g., an angle of 89.9° between two structural features) is also within the scope of mutual perpendicularity in this application. Similarly, the parallelism in this application is not absolute parallelism. Approximate parallelism due to processing and assembly errors (e.g., an angle of 0.1° between two structural features) is also within the scope of mutual parallelism in this application. The definitions of mutual parallelism and mutual perpendicularity will not be repeated below.
[0039] Additionally, it should be noted that the directional terms such as "upper," "lower," "left," "right," "front," "back," "top," and "bottom" used in this document are exemplary orientations of the plate 1, and do not indicate or imply that the device referred to must have a specific orientation. These orientations may vary depending on actual use and should not be construed as limitations on this application.
[0040] Referring to Figure 1, the plate 1 includes a back shell 10, a frame 20, and a connector assembly 30. The frame 20 surrounds the back shell 10 circumferentially and together with the back shell 10 forms a receiving cavity S1. A first through hole 21 is also provided on the frame 20, which connects the receiving cavity S1 and the outside of the plate 1.
[0041] The connector assembly 30 includes a connector 31 and a connector board 32. A portion of the connector 31 (e.g., a first portion 311) is located in a first through-hole 21 and exposed to the outside of the plate 1 via the first through-hole 21 for electrical connection with a counterpart connector (not shown) outside the plate 1. Another portion of the connector 31 (e.g., a second portion 312) is located within a receiving cavity S1 and is connected to the connector board 32 (e.g., soldered). The connector board 32 can be connected to other electronic devices inside the plate 1, thereby enabling functions such as charging or signal transmission. Exemplarily, the connector board 32 can be electrically connected to a mainboard 34 via a flexible printed circuit (FPC), allowing the connector assembly 30 to transmit signals with the mainboard 34.
[0042] To prevent moisture from entering the interior of the tablet 1 and damaging the electronic components inside the tablet 1 (such as connector board 32, flexible circuit board 33 and motherboard 34), a waterproof design is required for the location of the connector assembly 30.
[0043] It is understood that in the example shown in Figure 1, the connector assembly 30 is positioned near the bottom of the plate 1, and correspondingly, a waterproof structure needs to be designed at the bottom of the plate 1. However, this application is not limited to this; in other embodiments, the connector assembly 30 can also be positioned elsewhere. For example, the connector assembly 30 can also be positioned near the top of the plate 1, and correspondingly, a waterproof structure can be designed at the top of the plate 1. Furthermore, this application does not impose a specific limitation on the number of connector assemblies 30; the number of connector assemblies 30 can be one or more (e.g., two, three, or four, etc.) to transmit different signals, and correspondingly, the same number of waterproof structures can be designed on the plate 1.
[0044] The following section uses the connector assembly 30 located near the bottom of the flat plate 1 in the example shown in Figure 1 above as an example to introduce an exemplary waterproof design scheme corresponding to the connector assembly 30.
[0045] Figure 2A illustrates an exemplary structure of a waterproof plate 1 in some technical solutions. Figure 2B illustrates an exemplary structure of the connector assembly 30 in the plate 1 in some technical solutions, based on Figure 2A. For ease of observation, the first portion 311 and the second portion 312 of the connector 31 are shown in different shades in Figure 2A.
[0046] Referring to Figures 2A and 2B, in some technical solutions, the connector 31 of the connector assembly 30 includes a housing 313 and a tongue 314. The housing 313 covers the tongue 314 to protect it. The tongue 314 has multiple terminals for electrical connection with the terminals of the opposite connector 2, thereby enabling signal transmission. The connector board 32 of the connector assembly 30 is a printed circuit board (PCB).
[0047] To facilitate the installation and waterproofing of the connector assembly 30, the flat plate 1 further includes a pressure block 100 and an elastic seal 200. The pressure block 100 presses the connector assembly 30 onto the back cover 10 and secures it to the back cover 10 with screws 50. The elastic seal 200 provides a sealed connection between the components. Specifically, the elastic seal 200 may include a first seal 201, a second seal 202, and a third seal 203. The first seal 201 is located between the pressure block 100 and the connector assembly 30, the second seal 202 is located between the pressure block 100 and the frame 20, and the third seal 203 is located between the back cover 10 and the connector assembly 30. After the pressure block 100 presses the connector assembly 30, the first seal 201, the second seal 202, and the third seal 203 of the elastic seal 200 are all in a compressed state. As a result, the first seal 201 can fully fill the installation gap between the pressure block 100 and the connector assembly 30, the second seal 202 can fully fill the installation gap between the pressure block 100 and the frame 20, and the third seal 203 can fully fill the installation gap between the back cover 10 and the connector assembly 30, thus achieving a reliable seal.
[0048] The pressure block 100 may include a second through hole 101 extending along the Z direction, and the orthographic projection of the second portion 312 of the connector 31 on the pressure block 100 at least partially overlaps with the second through hole 101. Thus, in region S2, the solid portion of the pressure block 100 and the second portion 312 of the connector 31 are offset in the Z direction, thereby compressing the distribution space of the pressure block 100 and the connector 31 in the Z direction, and thus the pressure block 100 can avoid other devices (e.g., the display screen 40) of the flat plate 1.
[0049] It is worth noting that, to prevent moisture from entering the interior of the plate 1 through the second through hole 101, the first seal 201 of the elastic seal 200 also blocks the second through hole 101. Thus, in region S2, the first seal 201 of the elastic seal 200, the second part 312 of the connector 31, and the display screen 40 are stacked along the Z direction. Since the first seal 201 of the elastic seal 200 also has a certain thickness, the overall stack thickness of the components in region S2 is difficult to further reduce, which is detrimental to the thinner design of the plate 1. To further thin the plate 1, the display screen 40 and the pressure block 100 must be offset in the Z direction, but this results in a larger size of the plate 1 along the XY plane, and the display screen 40 cannot be set too large, which is detrimental to the miniaturized narrow bezel design of the plate 1.
[0050] To address the aforementioned issues, this application embodiment removes the portion of the elastic seal used to block the second through hole and provides a sealing film on the side of the second through hole facing away from the connector assembly. By sealing the second through hole with the sealing film, the sealing film can occupy a smaller thickness space, thus effectively saving layout space in the Z direction to meet the thinning requirements of the flat plate, while not increasing the size of the flat plate along the XY plane, which is beneficial for the miniaturization design of the flat plate.
[0051] The technical solution of this application is described below with reference to the accompanying drawings.
[0052] Figures 3A to 3C show exemplary structures of a waterproof flat plate 1 in embodiments of this application. Figure 3A is a perspective view of a portion of the structure of the flat plate 1, Figure 3B is a cross-sectional view of a portion of the structure of the flat plate 1 along section AA in Figure 3A, and Figure 3C is an exploded view of a portion of the structure of the flat plate 1 along the Z direction. For ease of observation, the first part 311 and the second part 312 of the connector 31 are shown in Figure 3A with different shades of areas. Figure 3B also shows the display screen 40 of the flat plate 1.
[0053] Referring to Figures 3A to 3C, the flat plate 1 includes a back shell 10, a frame 20, a connector assembly 30, a pressure block 100, an elastic seal 200, and a sealing membrane 300.
[0054] The back cover 10 generally presents a flat structure extending along the XY plane. In some embodiments, the back cover 10 can be a flat plate structure, in which case the back cover 10 can be parallel to the XY plane. In other embodiments, the back cover 10 can also be a curved plate structure, for example, the back cover 10 has slight convex or concave arcs while extending along the XY plane. It is understood that the surface of the back cover 10 can be uneven to meet the device mounting requirements and appearance design requirements.
[0055] The frame 20 has a frame-like structure and stands sideways relative to the back shell 10 along the positive Z-direction. The frame 20 surrounds the back shell 10 circumferentially and together with the back shell 10, forms a receiving cavity S1. A first through hole 21 is provided on the frame 20. The first through hole 21 connects the receiving cavity S1 and the outside of the plate 1. It can be understood that the receiving cavity S1 is located on the side of the back shell 10 facing the positive Z-direction, or in other words, the back shell 10 and the receiving cavity S1 are arranged sequentially along the positive Z-direction.
[0056] In some embodiments, the back shell 10 and the frame 20 can be a single-piece structure. For example, the back shell 10 and the frame 20 can be made of plastic and formed into a single shell through injection molding. In other embodiments, the back shell 10 and the frame 20 can also be formed separately and then assembled together to form a shell.
[0057] In this embodiment, the back shell 10 and the frame 20 are both exterior parts of the tablet 1. That is, after the tablet 1 is assembled, the user can observe and touch the back shell 10 and the frame 20, but this application is not limited to this. In some other embodiments, the back shell 10 may also be an internal shell of the tablet 1. That is, after the tablet 1 is assembled, the user cannot observe or touch the back shell 10.
[0058] The connector assembly 30 includes a connector 31. A first portion 311 of the connector 31 is located in a first through-hole 21 and exposed to the outside of the plate 1 via the first through-hole 21. That is, after the plate 1 is assembled, the user can observe the first portion 311 of the connector 31 through the first through-hole 21, thus allowing the first portion 311 to be used for electrical connection with a counterpart connector (not shown) outside the plate 1. A second portion 312 of the connector 31 is located within a receiving cavity S1 and is used for connection with other devices. For example, in the embodiments shown in Figures 3A to 3C, the connector assembly 30 may also include a connector board 32 (as an example of a circuit board), to which the connector 31 can be connected (e.g., soldered). The connector board 32 can be connected to other electronic devices inside the plate 1. Exemplarily, as shown in Figure 1, the connector board 32 can be electrically connected to a motherboard 34 via a flexible printed circuit (FPC), allowing the connector assembly 30 to transmit signals with the motherboard 34. Thus, the plate 1 can achieve functions such as charging or signal transmission through the connector assembly 30.
[0059] The clamping block 100 presses the connector assembly 30 onto the back cover 10, thereby mounting the connector assembly 30. The clamping block 100 includes a second through hole 101 extending along the Z direction. Furthermore, the orthographic projection of the second portion 312 of the connector 31 onto the clamping block 100 at least partially overlaps with the second through hole 101, or in other words, the second through hole 101 and the second portion 312 of the connector 31 are stacked along the Z direction. Alternatively, it can be understood that the solid portion of the clamping block 100 and the second portion 312 of the connector 31 are offset in the Z direction.
[0060] The resilient seal 200 provides a sealing connection between the pressure block 100 and the connector assembly 30, between the pressure block 100 and the frame 20, and between the back cover 10 and the connector assembly 30. Exemplarily, in the embodiment shown in FIG. 3B, the resilient seal 200 may include, for example, a first seal 201, a second seal 202, and a third seal 203. The first seal 201 is disposed between the pressure block 100 and the connector assembly 30, the second seal 202 is disposed between the pressure block 100 and the frame 20, and the third seal 203 is disposed between the back cover 10 and the connector assembly 30. After the pressure block 100 presses the connector assembly 30, the first seal 201, the second seal 202, and the third seal 203 of the resilient seal 200 are all in a compressed state, thereby sufficiently filling the installation gaps between the pressure block 100 and the connector assembly 30, between the pressure block 100 and the frame 20, and between the back cover 10 and the connector assembly 30, ultimately achieving a reliable seal.
[0061] Compared to the elastic seal 200 in the schemes shown in Figures 2A and 2B above, the elastic seal 200 provided in this application differs in that the portion of the elastic seal 200 that is sealed between the pressure block 100 and the connector assembly 30 (e.g., the first seal 201) does not overlap with the second through hole 101 on the pressure block 100 when projected onto it. In other words, the second through hole 101 and the portion of the elastic seal 200 that is sealed between the pressure block 100 and the connector assembly 30 are offset in the Z direction.
[0062] A sealing film 300 is disposed on the side of the second through hole 101 facing away from the connector assembly 30 and blocks the second through hole 101 to prevent moisture from entering the interior of the plate 1 through the second through hole 101.
[0063] In the aforementioned tablet 1, the sealing film 300 can replace a portion of the elastic seal 200, or in other words, a portion of the thickness of the elastic seal 200 is replaced by the thickness of the sealing film 300. Compared to the elastic seal 200, the sealing film 300 has a smaller thickness. This effectively saves the layout space of the device in region S2 in the Z direction, thus meeting the thinner and lighter design requirements of the tablet 1; for example, the tablet 1 can be thinner by 0.3mm or more. Simultaneously, there is no need to offset the display screen 40 of the tablet 1 from the pressure block 100 in the Z direction, thus not increasing the size of the tablet 1 along the XY plane, and the display screen 40 can be set large enough to help achieve a narrow bezel design for the tablet 1; for example, the bezel of the tablet 1 can be narrowed by 0.3mm or more.
[0064] The exemplary structures of the connector assembly 30, pressure block 100, elastic seal 200, and sealing membrane 300 in the waterproof solution provided in this application will be described in detail below with reference to the accompanying drawings.
[0065] In some embodiments of this application, the connector 31 of the connector assembly 30 is a connector with a housing. Specifically, FIG4 shows an exemplary structure of the connector assembly 30 in an embodiment of this application. Referring to FIG4, the connector 31 may include a housing 313 and a tongue 314. The housing 313 covers the outside of the tongue 314 to protect the tongue 314. The tongue 314 has multiple terminals for electrical connection with the terminals of the opposite connector 2, thereby enabling signal transmission. The connector board 32 of the connector assembly 30 is a printed circuit board (PCB). This type of connector assembly 30 has lower cost and wider application range.
[0066] In some of these implementations, the material of the housing 313 of the connector 31 can be, for example, metal (e.g., iron, steel, etc.) to provide reliable support and protection for the entire connector 31.
[0067] Figures 5A and 5B illustrate an exemplary structure of the pressure block 100 in an embodiment of this application. Figure 5A is a perspective view of the pressure block 100, with the location of the adhesive 400 shown in the area filled with grid lines. Figure 5B is a top view of the pressure block 100, with the location of the sealing film 300 shown in the area filled with dots. Figure 5C shows a schematic diagram of the cooperation between the pressure block 100 and the connector assembly 30 in an embodiment of this application.
[0068] Referring to Figures 5A to 5C, the pressure block 100 may include a first part 110, a second part 120, and a third part 130 connected in sequence. The first part 110 is pressed onto the connector 31, and the third part 130 is pressed onto the connector plate 32. Furthermore, along the Z-direction, the distance between the first part 110 and the display screen 40 is less than the distance between the third part 130 and the display screen 40. That is, along the Z-direction, the first part 110 is closer to the display screen 40 than the third part 130. It can be understood that, to achieve the connection between the first part 110 and the third part 130, the second part 120 is inclined relative to the first part 110 and the third part 130. Therefore, at the second part 120, the distance between the pressure block 100 and the display screen 40 gradually decreases.
[0069] The second through hole 101 is formed on the second part 120, which can effectively save the layout space of the second part 120 of the pressure block 100 in the Z direction, so that the pressure block 100 can avoid the display screen 40.
[0070] Referring again to Figures 5A to 5C, in some embodiments of this application, the clamping block 100 includes a first surface 111, and the connector 31 includes a second surface 315. The first surface 111 and the second surface 315 are disposed opposite to each other along the Z direction and abut against each other. That is, the first surface 111 and the second surface 315 are in contact, and there is a force between the first surface 111 and the second surface 315. In this way, the clamping force of the clamping block 100 can be effectively transmitted from the first surface 111 to the second surface 315, thereby providing better clamping force to the connector 31 and making the installation stability of the connector 31 better.
[0071] In some implementations, the first surface 111 and the second surface 315 are similar in shape; that is, the first surface 111 and the second surface 315 are two compatible surfaces. This allows the pressure block 100 to fit better with the connector 31, thereby further improving the clamping effect of the pressure block 100. For example, the first surface 111 is a plane perpendicular to the Z direction, and correspondingly, the second surface 315 can also be a plane perpendicular to the Z direction. Alternatively, the first surface 111 can be a curved surface convex in the positive Z direction, and correspondingly, the second surface 315 can also be a curved surface convex in the positive Z direction.
[0072] Referring again to Figures 5A to 5C, in some embodiments of this application, the pressure block 100 and the back shell 10 are fixedly connected by fasteners. For example, the fastener can be a screw 50, which can be sequentially inserted into the pressure block 100 and the back shell 10 along the Z direction, and the tail of the screw 50 is fixed to the back shell 10 by threads. In other embodiments, the pressure block 100 and the back shell 10 can also be fixedly connected by other means, such as other fastener connections (e.g., bolt connections), adhesives, snap-fits, etc. This application does not limit these methods, as long as the pressure block 100 can achieve the above-mentioned clamping effect.
[0073] Referring again to Figures 5A to 5C, in some embodiments of this application, the pressure block 100 has a groove 102 on its surface facing the display screen 40. The groove 102 is used to accommodate the sealing film 300 and the adhesive backing 400. The sealing film 300 is bonded to the pressure block 100 by the adhesive backing 400. In this way, the stacking thickness of the pressure block 100, the sealing film 300, and the adhesive backing 400 along the Z direction can be further reduced, thereby meeting the thin and light design requirements of the flat panel 1.
[0074] It should be noted that in this embodiment, the sealing film 300 is bonded to the pressure block 100 via adhesive 400 to achieve a fixed connection between the sealing film 300 and the pressure block 100. In other embodiments, the sealing film 300 may also be fixedly connected to the pressure block 100 via fasteners, snap-fitting, or welding. This application does not impose any restrictions on this, as long as the sealing film 300 can achieve a sealing effect.
[0075] In some embodiments of this application, the material of the pressing block 100 can be a powder metallurgy material. This can effectively improve the mechanical properties of the pressing block 100, resulting in better strength.
[0076] In some implementations, the briquette 100 can be formed by metal injection molding (MIM), which makes the production efficiency of the briquette 100 higher and the manufacturing cost lower.
[0077] In other embodiments of this application, the material of the pressure block 100 can also be a die-cast material (e.g., die-cast zinc alloy), that is, the pressure block 100 can also be a die-cast part. In this way, production costs can be further reduced, and it is easier to form pressure blocks 100 of various shapes so that the first surface 111 of the pressure block 100 can be better adapted to the second surface 315 of the connector 31.
[0078] In other embodiments of this application, the material of the pressure block 100 may also be a material that can be processed by a computer numerical control machine tool (CNC), such as steel, aluminum profiles, etc.
[0079] In some embodiments of this application, the material of the sealing membrane 300 may be, for example, metal (e.g., steel or copper) or polyethylene terephthalate (PET). It is understood that the sealing membrane 300 may be a flexible membrane to adapt to the application requirements of various application scenarios. Alternatively, in some other alternative implementations, the sealing membrane 300 may also be a membrane with a certain rigidity to improve the strength and reliability of the overall structure; this application does not impose specific limitations in this regard.
[0080] In some embodiments of this application, the thickness of the sealing film 300 may be less than or equal to 0.1 mm, for example, 0.1 mm, 0.09 mm, 0.08 mm, 0.07 mm, etc. This allows the sealing film 300 to be thin enough to meet the thinning requirements of the plate 1.
[0081] In some implementations, the thickness of the sealing membrane 300 can be, for example, 0.03mm-0.1mm, such as 0.03mm, 0.04mm, 0.05mm, 0.06mm, etc. This ensures that the thickness of the sealing membrane 300 is neither too large nor too small, thereby meeting the thinning requirements of the flat plate 1 while ensuring the waterproof sealing effect of the sealing membrane 300.
[0082] Figure 6 illustrates an exemplary structure of the resilient seal 200 in an embodiment of this application. Referring to Figure 6 and in conjunction with Figure 3B, as previously described, in some embodiments of this application, the resilient seal 200 may include a first seal 201, a second seal 202, and a third seal 203. The first seal 201 is disposed between the pressure block 100 and the connector assembly 30 to achieve a sealed connection between the pressure block 100 and the connector assembly 30; the second seal 202 is disposed between the pressure block 100 and the frame 20 to achieve a sealed connection between the pressure block 100 and the frame 20; and the third seal 203 is disposed between the back cover 10 and the connector assembly 30 to achieve a sealed connection between the back cover 10 and the connector assembly 30.
[0083] In some embodiments of this application, the orthographic projection of the third seal 203 of the elastic seal 200 onto the back cover 10 does not overlap with the orthographic projection of the second portion 312 of the connector 31 onto the back cover 10. Alternatively, the third seal 203 and the connector 31 are offset in the Z direction. Compared to the third seal 203 in the solutions shown in Figures 2A and 2B, the third seal 203 provided in this application can avoid the connector 31, thereby saving some layout space in the Z direction. This further facilitates the achievement of the thinner and lighter design requirements of the flat panel 1.
[0084] In some embodiments of this application, the resilient seal 200 may further include a fourth seal 204, through which the first seal 201 and the third seal 203 are connected, and the second seal 202 and the third seal 203 are also connected through the fourth seal 204. The first seal 201 is also connected to the second seal 202, thereby integrating the first seal 201, the second seal 202, the third seal 203, and the fourth seal 204 into a single unit. The fourth seal 204 may, for example, be disposed between the frame 20 and the connector assembly 30.
[0085] In some embodiments of this application, the elastic seal 200 can be a one-piece structure, that is, the elastic seal 200 is integrally molded, thereby improving the sealing effect of the elastic seal 200. For example, the first seal 201, the second seal 202, the third seal 203, and the fourth seal 204 of the elastic seal 200 can be made of rubber, silicone, etc., and the first seal 201, the second seal 202, the third seal 203, and the fourth seal 204 can be integrally molded by means of molding, injection molding, etc., to obtain the elastic seal 200.
[0086] In other embodiments of this application, the elastic seal 200 may also be a split structure, that is, different parts of the elastic seal 200 may be molded separately and then assembled together to form the elastic seal 200. This application does not limit this.
[0087] After introducing the exemplary structures of each component in the waterproofing solution provided in the embodiments of this application, the following describes a comparison between the waterproofing solution provided in the embodiments of this application and waterproofing solutions in other technical solutions.
[0088] Figure 7A illustrates an exemplary structure of a waterproof plate 1 in some other technical solutions. Figure 7B illustrates an exemplary structure of the connector assembly 30 in the plate 1 in some other technical solutions, based on Figure 7A.
[0089] Referring to Figures 7A and 7B, in some other technical solutions, the connector 31 of the connector assembly 30 includes a tongue 314 but does not include a housing. The connector 31 is fixedly connected to the adapter 60 by fasteners, and the adapter 60 is fixedly connected to the back cover 10, thereby realizing the installation of the connector 31. The adapter 60 may, for example, be a metal powder injection molded part (or "MIM part"). The connector board 32 of the connector assembly 30 is a flexible circuit board, which has a certain degree of flexibility and deformation capability, and can better adapt to the installation method of the connector 31.
[0090] To achieve waterproofing of the connector assembly 30, the flat plate 1 also includes a waterproof rubber ring 70, which is sleeved on the outside of the tongue 314 to achieve a sealed connection between the tongue 314 and the adapter 60.
[0091] In the waterproofing solutions shown in Figures 7A and 7B, the connector 31 of the connector assembly 30 is a shell-less connector, which places higher demands on the performance of the tongue 314. Furthermore, the connector board 32 is a flexible circuit board, resulting in a higher overall component cost for the connector 31. Additionally, the soldering process between the connector 31 and the connector board 32 is also costly, limiting its applicability. In contrast, the waterproofing solution in this application, as shown in Figure 4, allows the connector 31 of the connector assembly 30 to be a shell-equipped connector, and the connector board 32 to be a printed circuit board, resulting in lower overall cost and a wider range of applications.
