Description

Technical Field

[0001] The present application relates to the technical field of electronic device frames, and in particular to a frame assembly and an electronic device. Background Art

[0002] Among existing electronic device protection solutions, the unibody architecture is widely used, particularly in mobile phones, due to its low cost and simple structure. The unibody architecture primarily consists of a battery back cover, a housing, a midframe, and a display assembly. However, this commonly used unibody architecture suffers from several drawbacks in practical applications:

[0003] In the Unibody architecture, the shell is put on the middle frame, and the middle frame and the shell are usually matched with snap-on inserts and fixed with screws. Due to the limitations of the assembly and matching process, it is impossible to achieve zero-gap matching between the middle frame and the shell. There is usually a gap of 0.02mm-0.15mm, which forms a channel for liquid to enter the interior of the device. The end of the channel can usually be sealed with sealing foam, etc., but the front end of the channel is mainly caused by the assembly requirements of the front and rear shells, and cannot be sealed with sealing foam or other structures, otherwise it will affect the assembly. When external liquid enters the gap between the middle frame and the shell, the liquid can quickly enter the interior of the device, and sealing structures such as protective foam cannot be effectively sealed, which makes the electronic device have a higher risk of liquid ingress. In this case, the liquid will quickly impact the internal components, causing damage to the equipment. Summary of the Invention

[0004] The present application provides a frame assembly and an electronic device, wherein the frame assembly is used to prevent liquid from entering the interior of the electronic device through a gap between a middle frame and a shell.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, a frame assembly is provided for an electronic device, the frame assembly comprising a middle frame and a shell mounted on the periphery of the middle frame; at least one water storage tank is provided on the outer wall of the middle frame and / or the inner wall of the shell, the water storage tank extending along the circumference of the frame assembly, and the water storage tank is used to store water that enters between the outer wall of the middle frame and the inner wall of the shell.

[0007] The frame assembly provided in the embodiment of the present application extends the liquid flow path through the water storage tank, increases the resistance to liquid flow, thereby greatly reducing the speed and range of liquid diffusion inside the device, providing more efficient liquid-proof protection for electronic equipment, significantly improving the liquid-proof performance of electronic equipment, and reducing the risk of liquid damaging electronic components inside the device.

[0008] In one embodiment, multiple leak-prone areas are defined between the outer wall of the middle frame and the inner wall of the housing. Multiple water storage tanks are provided, with at least one tank installed in each leak-prone area. The provision of water storage tanks effectively prevents liquid from flowing into these vulnerable areas, preventing it from entering the device interior and reducing the risk of liquid damage. The design of having at least one water storage tank in each leak-prone area provides targeted protection, effectively enhancing its effectiveness.

[0009] In one embodiment, the housing is provided with a drain port connected to the outside. Multiple water tanks are provided, with the end of at least one of the tanks connected to the drain port. The coordination of the water tank and the drain port ensures that any liquid entering the device is promptly directed and drained. Liquid does not accumulate within the device, preventing long-term damage to internal components. This effective drainage mechanism allows the water tank to not only store and direct liquid but also quickly drain it through the drain port, further enhancing the device's waterproof performance.

[0010] In one embodiment, a drainage recess is provided on the outer wall of the middle frame. The position of the drainage recess corresponds to the position of the drain outlet, and the end of at least one water storage tank is connected to the drainage recess. This allows the liquid in the water storage tank to be smoothly guided to the drainage recess and then discharged to the outside of the device through the drain outlet, effectively reducing the time the liquid stays inside the device.

[0011] In one embodiment, the frame is provided with a port portion for making way for the port of the electronic device, and the port portion is opened on the bottom wall of the drainage recess. Since the port of the electronic device usually has a certain degree of waterproof capability, the drain port is located at the port portion, and the water is drained through the port portion, achieving a dual purpose. That is, the drain port can be used for both plugging and unplugging the port and for draining water, making full use of the waterproof performance of the port, ensuring that liquid will not accumulate inside the device, and further improving the waterproof effect of the device. This layout optimizes the utilization rate of the internal space of the device, makes the layout between the components more reasonable, and avoids space waste.

[0012] In one embodiment, the frame assembly is further provided with other functional slots, with at least one water storage slot being longer than the other functional slots provided on the outer sidewall of the middle frame and / or the inner sidewall of the housing. Longer water storage slots provide greater water storage capacity, allowing for greater storage capacity when liquid enters the device, reducing the risk of liquid spreading within the device. Longer water storage slots can provide protection over a wider area, effectively capturing and storing liquid regardless of where it enters the device, improving the overall protection of the device.

[0013] In one embodiment, the plurality of water tanks comprises at least one water tank group, each of which includes multiple water tanks spaced apart along the thickness of the frame assembly. By spacing the multiple water tanks apart along the thickness of the frame assembly, a multi-layered protective structure is formed. Each layer of water tanks blocks and guides incoming liquid, gradually reducing its flow rate and pressure as it flows layer by layer, thereby significantly enhancing the overall waterproofing effect.

[0014] In one embodiment, at least one of the water storage grooves is 10 mm or longer. A longer water storage groove can direct more liquid to the drain outlet, achieving faster and more efficient drainage. Regardless of how the water storage groove is bent, its overall length ensures sufficient liquid guidance and storage capacity, preventing liquid accumulation within the device.

[0015] In one embodiment, the depth of the water tank is 0.05mm to 0.15mm, and the width of the water tank is 0.05mm to 0.2mm. Within this value range, the water tank can effectively increase the resistance to liquid flow and slow down the rate of liquid diffusion. The water tank can form an effective retention area, disperse the liquid pressure, and reduce the impact of the liquid on the protective foam. The increased resistance to the liquid in the water tank helps to slow down the flow rate of the liquid, thereby reducing the impact on internal components. Appropriate tank depth and width ensure that the water tank does not significantly increase the thickness of the frame assembly or affect its structural strength.

[0016] In one embodiment, a first gap is defined between the outer wall of the middle frame and the inner wall of the housing. The first gap, multiple water storage grooves, and other functional grooves collectively form a drainage cavity arranged circumferentially along the frame assembly. The circumferential arrangement of the drainage cavity allows liquid to be evenly distributed and flowed around the entire frame assembly, forming a complete circuit around the circumference of the drainage cavity, allowing for multiple points of convergence and centralized drainage.

[0017] In one embodiment, the outer end wall of the middle frame and the inner end wall of the shell have a partially overlapping projection in the Z direction of the frame assembly, and a second gap is provided between the outer end wall of the middle frame and the inner end wall of the shell, and the second gap is connected to the first gap. The frame assembly further includes a sealing portion, which is arranged in the second gap, thereby enhancing the sealing and waterproof performance of the device.

[0018] In one embodiment, the other functional slots include snap-fit ​​slots. A snap is provided on the inner sidewall of the housing, and the snap-fit ​​slot is provided on the outer sidewall of the middle frame. The housing is connected to the middle frame via the snap-fitting engagement with the snap-fitting slot. The snap-fitting engagement with the snap-fitting slot provides a stable structural connection, making the connection between the housing and the middle frame more secure and reliable. This effectively prevents loosening or falling off of components, improving the overall stability and durability of the device.

[0019] In one embodiment, the water storage tank is linear or zigzag.

[0020] The second aspect of the present application provides an electronic device, which includes a frame assembly, a battery assembly and a control assembly installed in the frame assembly, a screen assembly and a back cover installed on the frame assembly, the screen assembly and the back cover are located on opposite sides of the frame assembly, and the frame assembly is the above-mentioned frame assembly.

[0021] Through the above technical solution, since the electronic device includes the above frame assembly, it at least has all the beneficial effects of the frame assembly, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] In order to make the purpose, technical solutions and advantages of this application more clear, this application is further described in detail below with reference to the accompanying drawings and embodiments.

[0054] In related technologies, the unibody architecture is widely used, especially in mobile phones, due to its low cost and simple structure. The unibody architecture mainly consists of a battery back cover, a housing, a middle frame, and a screen assembly. The combination of the housing and the middle frame has lower processing costs compared to only having a middle frame. However, this commonly used unibody architecture has several drawbacks in actual applications:

[0055] In the Unibody architecture, the shell is put on the middle frame, and the middle frame and the shell are usually matched with snap-on inserts and fixed with screws. Due to the limitations of the assembly and matching process, it is impossible to achieve zero-gap matching between the middle frame and the shell. There is usually a gap of 0.02mm-0.15mm, which forms a channel for liquid to enter the interior of the device. The end of the channel can usually be sealed with sealing foam, etc., but the front end of the channel is mainly caused by the assembly requirements of the front and rear shells, and cannot be sealed with sealing foam or other structures, otherwise it will affect the assembly. When external liquid enters the gap between the middle frame and the shell, the liquid can quickly enter the interior of the device, and sealing structures such as protective foam cannot be effectively sealed, which makes the electronic device have a higher risk of liquid ingress. In this case, the liquid will quickly impact the internal components, causing damage to the equipment.

[0056] The frame assembly in the embodiment of the present application is used for electronic devices, wherein electronic devices refer to various electronic products including but not limited to mobile phones, tablet computers, smart watches, etc. The frame assembly is a structural unit in the electronic device, usually composed of multiple parts, providing the basic shell and support protection of the device. The frame assembly of the present application includes a middle frame 10 and a shell 20 mounted on the periphery of the middle frame 10; wherein the middle frame 10 is the main structural part of the frame assembly, which is used to support and fix the internal components of the electronic device, such as batteries, motherboards and other electronic components. The middle frame 10 is made of metal or plastic material, providing basic strength and structural stability for the device. The shell 20 is an external covering layer mounted on the periphery of the middle frame 10, which usually protects the internal components of the device from the external environment. The shell 20 can be made of plastic, metal or other materials to provide protection and aesthetic functions.

[0057] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, at least one water storage tank 11 is provided on the outer wall of the middle frame 10 and / or the inner wall of the shell 20 in the embodiment of the present application. The water storage tank 11 extends along the circumference of the frame assembly and is used to store water that enters between the outer wall of the middle frame 10 and the inner wall of the shell 20. It should be noted that the outer wall of the middle frame 10 refers to the outer surface of the side of the middle frame 10, that is, the surrounding part of the middle frame 10, opposite to the inner wall of the shell 20. The inner wall of the shell 20 refers to the surface of the inner side of the shell 20, opposite to the outer wall of the middle frame 10. The water storage tank 11 is a groove provided on the outer wall of the middle frame 10 and / or the inner wall of the shell 20, used to store water that enters between the middle frame 10 and the shell 20. The water storage tank 11 extends along the circumference of the frame assembly to form a path for guiding and storing liquid. Circumferential extension means that the water tank 11 extends along the circumferential direction of the frame assembly, rather than along the thickness direction of the frame assembly, which can effectively store and block moisture entering between the middle frame 10 and the shell 20. Among them, the water tank 11 can also be called a labyrinth tank. The water tank 11 extends the path of liquid flow and increases the resistance to liquid flow, thereby greatly reducing the speed and range of liquid diffusion inside the device, and reducing the risk of liquid damaging the electronic components inside the device. The liquid in the water tank 11 in the embodiment of the present application can evaporate naturally, or the liquid can be quickly discharged by providing an opening on the shell 20. In summary, the frame assembly provides more efficient liquid-proof protection for the electronic device by providing the water tank 11 (labyrinth tank), extending the liquid path, increasing flow resistance, forming a retention area and improving sealing, thereby significantly improving the liquid-proof performance of the electronic device. In one embodiment, the water tank 11 in the embodiment of the present application is provided on the outer wall of the middle frame 10.

[0058] It should be noted that the water tank 11 is a labyrinthine trough specifically designed for waterproofing purposes, and its design primarily considers how to effectively store, guide, and drain liquids. The other functional slots on the frame assembly are used for functions such as device connection, support, and interface clearance. These slots primarily focus on mechanical connection stability and ease of operation, and do not serve or function as waterproofing. The presence of the water tank 11 increases the length of the path the liquid travels within the device. When liquid enters the water tank 11, it must follow a tortuous path within the tank 11 rather than passing directly through the device. This circuitous path increases the liquid's flow resistance, making it more difficult for the liquid to quickly pass through the tank 11, thereby slowing its flow rate. As the liquid flows through the water tank 11, it is obstructed by the tank walls and subjected to pressure. The presence of the water tank 11 (labyrinthine trough) creates multiple tortuous and turning areas during the liquid flow process, which can be considered liquid retention zones. Within these areas, the liquid flow rate slows down or even temporarily stagnates, increasing the time the liquid remains within the device and reducing the likelihood of the liquid entering other parts of the device.

[0059] In the embodiments of the present application, multiple leak-prone areas are located between the outer wall of the middle frame 10 and the inner wall of the housing 20. These areas are typically areas with weak waterproofing, typically corresponding to device buttons, antenna seams, and coaxial cable locations. Keys typically require sensitive operation, so their design often takes into account their contact with the external environment, resulting in gaps or clearances around them. Device buttons are often leak-prone areas. In electronic devices, antennas often need to connect to the device's housing, forming a transmission channel between the antenna and external signals. Antenna seams often have connection interfaces or gaps. These areas, due to their large contact area or design requirements, can easily become pathways for liquids to enter the device. Coaxial cables are typically used to transmit electrical or wireless signals and therefore need to connect to the device's housing, forming a signal transmission path. Coaxial cables may have connection gaps or interfaces, making them vulnerable to liquid intrusion. Specifically, the provision of a water reservoir 11 effectively prevents liquids from flowing into these vulnerable areas, preventing them from entering the device's interior and reducing the risk of liquid damage. The design of setting at least one water storage tank 11 in each leak-prone area can form targeted protection and effectively improve the protection effect. In addition, the buckle position and the bone insertion position are also leak-prone positions.

[0060] See also Figure 5 、 Figure 6 、 Figure 7 、 Figure 16 and Figure 17 As shown, the housing 20 in the embodiment of the present application is provided with a drain port 21 connected to the outside, and there are multiple water tanks 11, and the end of at least one water tank 11 is connected to the drain port 21. When external liquid enters the interior of the device, it enters the water tank 11 through the gap between the middle frame 10 and the housing 20. The liquid flows in the water tank 11 and is guided to the drain port 21 along the path of the water tank 11. The liquid flows out of the device through the drain port 21 to avoid accumulation inside the device. The cooperation between the water tank 11 and the drain port 21 ensures that the liquid entering the device can be guided and discharged in a timely manner. The liquid will not accumulate inside the device, avoiding long-term damage to the internal components by the liquid. Through the above-mentioned effective drainage mechanism, the water tank 11 can not only store and guide the liquid, but also quickly discharge the liquid through the drain port 21, further enhancing the waterproof performance of the device. The provision of the drain port 21 ensures that the interior of the device will not become damp due to liquid accumulation, thereby avoiding problems such as short circuits and corrosion of internal components caused by moisture.

[0061] See also Figures 10 to 12As shown, a drainage recess 14 is provided on the outer wall of the middle frame 10 in the embodiment of the present application. The position of the drainage recess 14 corresponds to the position of the drain outlet 21, and the end of at least one water storage tank 11 is connected to the drainage recess 14. The embodiment of the present application significantly improves the accuracy of liquid guidance and drainage efficiency. By having the drainage recess 14 correspond to the drain outlet 21, the retention time of the liquid inside the device is reduced, the waterproof performance of the device is enhanced, the internal components are protected, and the service life of the device is extended. Specifically, a drainage recess 14 is provided on the outer wall of the middle frame 10, and its position is ensured to correspond to the position of the drain outlet 21 on the shell 20, providing sufficient drainage space to avoid blockage. The liquid in the water storage tank 11 can be smoothly guided to the drainage recess 14, and then discharged to the outside of the device through the drain outlet 21, effectively reducing the retention time of the liquid inside the device.

[0062] See also Figures 10 to 12 As shown, the frame in the embodiment of the present application is provided with a port portion 12 for making way for the port of the electronic device, and the port portion 12 is opened on the bottom wall of the drainage recess 14. Among them, the ports of the electronic device include charging ports, headphone jacks or data interfaces, etc. Since the ports of electronic devices usually have a certain degree of waterproof ability, the position of the drain port 21 is set at the position of the port portion 12, and the water is drained through the port portion 12, achieving a dual purpose. That is, the drain port 21 can be used for both plugging and unplugging the port and draining water, making full use of the waterproof performance of the port, ensuring that liquid does not accumulate inside the device, and further improving the waterproof effect of the device. The port portion 12 is set on the bottom wall of the drainage recess 14, so that the drainage design is combined with the port position. This layout optimizes the utilization rate of the internal space of the device, makes the layout between the components more reasonable, avoids space waste, improves the compactness and neatness of the internal design of the device, and at the same time ensures a simple appearance. Moreover, the integrated design of the port portion 12 and the drainage recess 14 simplifies the manufacturing and assembly process. The integrated design reduces the number of parts and assembly steps, improves production efficiency and product consistency, and reduces manufacturing costs.

[0063] See also Figures 13 to 15As shown, the frame assembly in the embodiment of the present application is also provided with other functional slots. The length of at least one water storage tank 11 is greater than the length of the other functional slots provided on the outer wall of the middle frame 10 and / or the inner wall of the housing 20. Among these, the other functional slots may include snap slots, bone insertion slots, retaining rib slots, card tray slots, headphone slots, USB slots, camera slots, shrink holes, glue pull slots, glue dispensing slots, and the like. The length of the water storage tank 11 in the embodiment of the present application refers to the straight-line length from one end of the water storage tank 11 to the other end in the horizontal direction of the frame assembly and is independent of the shape of the water storage tank 11. The water storage tank 11 in the embodiment of the present application is specifically used to store and guide liquid, ensuring that liquid does not accumulate within the device. The water storage tank 11 effectively prevents liquid from intruding into the device by extending the liquid path, increasing flow barriers, and forming retention areas. The other functional slots primarily serve to connect and secure the device. Each performs different functions and roles, and together they enhance the overall performance and reliability of the device. Their design length is typically short, sufficient to meet specific functions. The main function of the water tank 11 is to store and guide liquid to prevent liquid from invading the interior of the device. A longer water tank 11 can provide a larger water storage capacity, so that when liquid enters, it can store more liquid and reduce the risk of liquid spreading inside the device. The increased length of the water tank 11 can extend the flow path of the liquid inside the device. A longer flow path helps to disperse the flow rate and pressure of the liquid, thereby slowing down the impact of the liquid on the internal components and protecting the electronic components inside the device. A longer water tank 11 can provide protection in more areas. No matter where the liquid enters the device, the water tank 11 can effectively capture and store the liquid, improving the overall protection effect of the device. In contrast, at least one water tank 11 is longer than the other tanks and can cover a larger area to achieve better waterproofing and liquid guiding functions.

[0064] See also Figures 8 to 11As shown, the multiple water tanks 11 in the embodiment of the present application comprise at least one water tank group, each of which includes multiple water tanks 11 spaced apart along the thickness of the frame assembly. By spacing the multiple water tanks 11 apart along the thickness of the frame assembly, a multi-layered protective structure is formed. Each layer of water tanks 11 blocks and guides incoming liquid, gradually reducing its flow rate and pressure as it flows layer by layer, significantly enhancing the overall waterproofing effect. The spacing of the multiple water tanks 11 ensures that the liquid must pass through multiple water tanks 11 during its flow, extending the liquid's flow path. This increases the liquid's residence time within the frame assembly, helping to more fully store and guide the liquid and reducing the possibility of direct liquid intrusion into the device. The multi-layered design of the water tanks 11 enhances the sealing performance of the frame assembly. Each layer of water tanks 11 seals and blocks liquid, reducing the risk of leakage from gaps in the frame assembly and ensuring a more stable and secure internal environment for the device. It can provide effective protection at different thickness positions. If there is sufficient space, you can set up more strips to reduce liquid penetration.

[0065] The length of at least one water tank 11 in the embodiment of the present application is greater than or equal to 10 mm, providing a larger storage capacity. This allows the water tank 11 to accommodate more liquid, thereby reducing the possibility of liquid diffusion inside the device and improving liquid-proof performance. A longer water tank 11 can guide more liquid to the drain port 21, achieving faster and more effective drainage. No matter how the water tank 11 is bent, its total length ensures sufficient liquid guidance and storage capacity to prevent liquid accumulation inside the device. Regardless of the shape of the water tank 11, its length greater than or equal to 10 mm can provide sufficient path length to delay liquid penetration. For water tanks 11 with a length of less than 10 mm, the shorter length of the water tank 11 limits its liquid storage capacity, and it may overflow before the liquid accumulates to a certain amount. A short drainage path may lead to poor drainage, and the liquid stays inside the device for too long, increasing the risk of damage to internal components.

[0066] In combination with the working principle of the labyrinth groove and the limited space of the frame assembly, the depth of the water tank 11 in the embodiment of the present application is 0.05mm~0.15mm, and the width of the water tank 11 is 0.05mm~0.2mm. The water tank 11 can not only effectively prevent the rapid penetration of liquid, but also make full use of the limited space for liquid storage. Within this value range, the water tank 11 can effectively increase the resistance to liquid flow and slow down the speed of liquid diffusion. The water tank 11 can form an effective retention area, disperse the liquid pressure, and reduce the impact of the liquid on the protective foam. The increased resistance to the liquid in the water tank 11 helps to slow down the flow rate of the liquid, thereby reducing the impact on internal components. The appropriate groove depth and width ensure that the water tank 11 will not significantly increase the thickness of the frame assembly or affect its structural strength. Designed within this range, it can provide an effective waterproof solution without affecting the stability of the overall structure.

[0067] Specifically, in fluid mechanics, narrow channels increase the resistance of the fluid. Within the above-mentioned setting range, the liquid is subjected to greater frictional resistance and viscous resistance when passing through the water storage tank 11, which slows down the flow rate of the liquid. This can effectively control the diffusion of the liquid and prevent it from quickly entering other areas inside the device. When the fluid flows in the narrow water storage tank 11, the flow rate is reduced due to the narrow channel. The lower flow rate increases the residence time of the liquid in the tank, which helps to further slow down the liquid's penetration rate into the interior of the device. The water storage tank 11 can also induce the liquid to generate tiny vortices, which further increase the flow resistance of the liquid and cause the liquid to stay in the water storage tank 11 for a longer time. The generation of vortices can effectively reduce the kinetic energy of the liquid, further reduce its flow rate, and enhance the protective effect. At a microscopic scale, the capillary effect also comes into play. The capillary action causes the liquid to encounter additional resistance in the water storage tank 11, further slowing down the movement of the liquid.

[0068] See also Figure 3 and Figure 4As shown, there is a first gap 41 between the outer wall of the middle frame 10 and the inner wall of the shell 20 in the embodiment of the present application. The first gap 41, multiple water storage tanks 11 and other functional grooves together form a drainage cavity arranged circumferentially along the frame assembly. The first gap 41, the water storage tank 11 and other functional grooves together form a drainage cavity, which can effectively guide and control the flow path of the liquid. The water storage tank can be directly connected to the functional tank or indirectly connected through the first gap. After the liquid enters the first gap 41, it will be guided along the drainage cavity to the water storage tank 11 and finally discharged to the outside of the device through the drain port 21. The circumferential arrangement of the drainage cavity enables the liquid to be evenly distributed and flow around the entire frame assembly, forming a complete loop in the circumference of the drainage cavity, which can achieve multi-point convergence and centralized drainage. This uniformly distributed design ensures that the liquid will not be concentrated in a specific area, thereby reducing the risk of leakage caused by local liquid accumulation, and effectively draining the accumulated water through the drain port 21.

[0069] In the embodiment of the present application, a drainage cavity arranged circumferentially along the frame assembly is formed by a first gap 41 between the outer wall of the middle frame 10 and the inner wall of the shell 20, in combination with multiple water storage tanks 11 and other functional grooves. This not only significantly improves the waterproof ability of the equipment, but also optimizes liquid discharge, disperses liquid pressure, and improves sealing and structural stability.

[0070] See also Figure 3 and Figure 4As shown, the arrow represents the direction of liquid inlet. In the embodiment of the present application, the outer end wall of the middle frame 10 and the inner end wall of the shell 20 partially overlap in the Z direction of the frame assembly. A second gap 42 is defined between the outer end wall of the middle frame 10 and the inner end wall of the shell 20. The second gap 42 is connected to the first gap 41. The frame assembly further includes a sealing portion 30, which is disposed within the second gap 42. The X, Y, and Z directions of the frame assembly are the same as those of the electronic device. The X direction generally refers to the width direction of the device, the Y direction generally refers to the height direction of the device, and the XY plane refers to the plane formed by the width and height directions of the device. The parallel direction on the XY plane is the horizontal direction mentioned in this application. The Z direction of the frame assembly refers to the thickness direction. The overlapping projections refer to the partial relative thickness of the outer end wall of the middle frame 10 and the inner end wall of the shell 20. The parallel direction on the XY plane, i.e., the horizontal direction, ensures the stability and protection capability of the device in the width and height directions. Although the second gap 42 is also created between the housing 20 and the middle frame 10, unlike the first gap 41, a sealing portion 30 can be provided within the second gap 42, thereby enhancing the device's sealing and waterproof performance. The first gap 41, on the other hand, is primarily created between two parts during the assembly process, where a sealing portion 30 cannot be provided. Therefore, the water storage tank 11 structure provided in this embodiment of the present application provides more effective liquid-proof protection for the electronic device by extending the liquid path, increasing flow resistance, forming a retention area, and improving sealing, significantly enhancing the electronic device's liquid-proof performance. The sealing portion 30 can be a sealing foam or other sealing component.

[0071] Other functional slots in the embodiment of the present application include a snap-fit ​​slot 13. A snap is provided on the inner side wall of the housing 20. The snap-fit ​​slot 13 is provided on the outer side wall of the middle frame 10. The housing 20 is snap-fitted to the middle frame 10 through the engagement of the snap and the snap-fit ​​slot 13. The snap-fit ​​engagement with the snap-fit ​​slot 13 provides a stable structural connection, making the connection between the housing 20 and the middle frame 10 more secure and reliable. This effectively prevents loosening or falling off between components, improving the overall stability and durability of the device. The provision of the snap-fit ​​slot 13 allows for easy disassembly and assembly of the connection between the housing 20 and the middle frame 10, facilitating the repair and replacement of various components of the device.

[0072] The water tank 11 in the embodiment of the present application is linear or zigzag. The water tank 11 can be designed as a linear or zigzag shape based on actual needs, making it suitable for electronic devices of different shapes and sizes. The zigzag-shaped water tank 11 can fully utilize limited space, effectively increasing the liquid storage capacity. Compared to a linear water tank 11, the zigzag design can store more liquid within a limited space, improving the liquid-proofing effect. Furthermore, by designing different turning angles and lengths, the zigzag-shaped water tank 11 can extend the flow path of the liquid within the tank. This design can effectively increase the time the liquid remains within the water tank 11. By increasing the liquid flow path and turning points, the zigzag-shaped water tank 11 can effectively reduce the speed and range of liquid diffusion within the device, effectively reducing the risk of liquid damage to the device's internal electronic components. The zigzag-shaped water tank 11 can be L-shaped, Z-shaped, or U-shaped. The L-shaped zigzag: The water tank 11 starts from one end point and extends in one direction, then turns at a right angle to the other direction, forming an L-shaped zigzag. Z-shaped zigzag: The water tank 11 extends in one direction, then turns at a right angle to the other, and then turns again to form a Z-shaped zigzag. This design allows for a longer liquid storage path within a limited space, making it suitable for equipment that requires increased liquid storage capacity within a smaller space. U-shaped zigzag: The water tank 11 extends in one direction, then turns at a right angle to the other, and then extends again in the same direction after the turn, forming a U-shaped zigzag. The L, Z, and U mentioned above do not necessarily represent actual shapes but are suggested as similar shapes for ease of understanding.

[0073] In addition to straight and broken line types, the water tank 11 can also be of different shapes such as curved, annular, and spiral, and can be selected and designed according to actual needs and design requirements. The curved water tank 11 can use a curved design to increase its length, thereby increasing the storage capacity of the water tank 11. Compared with the straight water tank 11, the curved water tank 11 can store more liquid in the same space, and has improved liquid-proof performance. The annular water tank 11 allows liquid to flow continuously along the annular track. The annular structure of the annular water tank 11 can effectively store liquid, and its annular track provides sufficient capacity and space so that liquid can circulate and be stored in the water tank 11. The design of the spiral water tank 11 requires the liquid to flow along the spiral track during storage, which increases the flow path of the liquid. Compared with the straight or annular water tanks 11, the flow path of the spiral water tank 11 is more tortuous and extended.

[0074] Figures 18 to 20 In the labyrinth, the water storage tank is called a labyrinth or labyrinth tank. Test data show that adding a water storage tank can reduce the amount of liquid entering by 23.8%-57.1%. Figure 18 As shown in Figure 2, the amount of liquid inflow at different times is significantly lower when there is a water storage tank than when there is no water storage tank. Figure 19 As shown in the figure, the leak-prone areas such as the buckle position and the bone insertion position have significantly lower leak rates when there is a water tank than when there is no water tank. Figure 20 As shown, under the conditions of equal width and length, the liquid intake is when there is no water tank, a 0.5mm wide water tank, a 1mm wide water tank, and two 0.5mm wide water tanks are set along the thickness direction of the frame component. It can be seen that the longer the water tank is, the better the waterproof effect is, and the more water tanks are along the thickness direction of the frame component, the better the waterproof effect is.

[0075] The water storage tank in the embodiment of the present application is provided with multiple pits, which are spaced apart along the extension direction of the water storage tank. The pits can provide additional storage space for liquid flowing through the water storage tank, allowing the liquid to be temporarily retained within the pits during the flow process. The presence of multiple pits increases the resistance to the liquid flowing within the water storage tank. When the liquid encounters the pits, it needs to change its flow path, thereby enhancing the blocking effect. This slows the flow rate of the liquid, thereby reducing the risk of liquid entering the interior of the device.

[0076] According to a second aspect of the present application, an electronic device is provided, comprising a frame assembly, a battery assembly and a control assembly mounted within the frame assembly, a screen assembly mounted on the frame assembly, and a back cover, wherein the screen assembly and the back cover are located on opposite sides of the frame assembly, and the frame assembly is the frame assembly described above. The battery assembly is used for power supply, and the control assembly is responsible for various functions and operation management of the device, including a processor, memory, and sensors. The screen assembly is used to display images, text, and other content.
