Description

Technical Field

[0001] This application relates to the field of electronic devices, and more particularly to an electronic device. Background Technology

[0002] In electronic devices, pressure relief components are key components used to balance internal and external air pressure and release excess pressure. They are widely used in closed or semi-closed electronic devices such as smartphones, laptops, smart wearable devices (such as watches and headphones), and energy storage battery packs.

[0003] In order to ensure the air flow requirements of the pressure relief component, a separate hole is usually made on the electronic device. However, the separate hole method affects the overall appearance and sophistication of the electronic device. Utility Model Content

[0004] This application provides an electronic device that ensures sufficient airflow while maintaining a clean and aesthetically pleasing appearance. The technical solution is as follows:

[0005] This application provides an electronic device, comprising: a first frame assembly, a first display screen, a battery cover, and a pressure relief assembly;

[0006] The first frame assembly includes: a first frame and a first support member connected to each other. The first frame surrounds the outer periphery of the first display screen, and the first support member is distributed with the first display screen in a first direction, and the first support member is used to support the first display screen; the first direction is perpendicular to the display surface of the first display screen.

[0007] The battery cover is disposed along the first direction on the side of the first frame away from the first display screen;

[0008] The first support member has a pressure relief cavity on the side away from the first display screen, and the pressure relief assembly is connected to the side of the first support member away from the first display screen and covers the pressure relief cavity.

[0009] In the first direction, there is a first gap between the battery cover and the first frame; in the direction parallel to the display surface of the first display screen, there is a second gap between the first display screen and the first frame, and the pressure relief chamber communicates with the first gap and the second gap.

[0010] By designing the first and second gaps, the gas volume of the pressure relief component can be increased, allowing the gas inside the sealed cavity to be quickly discharged to the outside of the electronic device. This prevents damage to components due to excessive pressure inside the sealed cavity, or allows gas to quickly enter the sealed cavity to achieve pressure balance between the inside and outside of the sealed cavity. Simultaneously, if one gap is blocked due to assembly errors, the other gap can still ensure the gas flow requirements of the pressure relief component. Furthermore, since the first gap is located between the battery cover and the first frame, and the second gap is located between the first display screen and the first frame, the gas flow requirements of the pressure relief component are met by utilizing the assembly gaps between the battery cover and the first frame, and between the first display screen and the first frame. This eliminates the need for separate openings on the electronic device, preserving its overall appearance and sophistication.

[0011] In some possible implementations, in a direction parallel to the display surface of the first display screen, there is a communication channel between the battery cover and the first support member, the communication channel communicating with the pressure relief chamber, the first gap, and the second gap.

[0012] Thus, when an assembly error exists between the first display screen and the first frame, causing the second gap to be blocked, the first gap is connected to the pressure relief chamber through a connecting channel, allowing pressure relief to occur through the first gap. Alternatively, when an assembly error exists between the first frame and the battery cover, causing the first gap to be blocked, the second gap is connected to the pressure relief chamber through a connecting channel, allowing pressure relief to occur through the second gap.

[0013] In some possible implementations, the first support member has a first channel, one end of which is connected to the pressure relief chamber and the other end of which is connected to the connecting channel.

[0014] With this configuration, the first gap can be connected sequentially through the connecting channel, the first channel, and the pressure relief chamber. The second gap can also be connected sequentially through the connecting channel, the first channel, and the pressure relief chamber.

[0015] In some possible implementations, the battery cover has a first groove on the side facing the first channel, and the first groove and the side of the first support member where the first channel is disposed form the communicating channel; wherein, the first gap communicates with the first groove.

[0016] Compared to directly drilling holes in the battery cover or the first support member to form a connecting channel, in this embodiment, only a first groove needs to be opened in the battery cover. The connecting channel is formed by the first groove and the first support member, which can greatly reduce the processing complexity and cost, while avoiding the structural risks caused by deep hole processing.

[0017] In some possible implementations, a second channel is provided between the first frame and the first support member, one end of the second channel being connected to the connecting channel and the other end being connected to the second gap.

[0018] Compared to directly creating a hole in the first frame or the first support to form a second channel, in this embodiment, the second channel is formed between the first frame and the first support, which can significantly reduce processing complexity and cost, while avoiding the structural risks caused by deep hole processing.

[0019] In some possible implementations, the area of ​​the first opening connecting the second channel to the connecting channel is greater than the area of ​​the second opening connecting the second channel to the second gap.

[0020] Here, the first opening has a larger area to quickly receive the high-pressure gas flowing in from the connecting channel, avoiding gas congestion caused by the narrowness of the second gap. Simultaneously, the area of ​​the first opening is larger than that of the second opening. According to fluid dynamics principles, when gas enters from the larger first opening and flows towards the smaller second opening, the space contraction causes an increase in flow velocity. This accelerated gas can then pass through the second opening more quickly into the second gap, ultimately exiting the electronic equipment rapidly and reducing the risk of high-pressure damage to components.

[0021] In some possible implementations, in the first direction, the first frame assembly has a second groove on the side facing the battery cover, the second groove communicating with the communication channel, and the first opening distributed at one end of the second channel located on the groove surface of the second groove.

[0022] Here, the second groove is used to further increase the volume of the connecting channel in order to quickly balance the internal and external pressure difference. At the same time, the second groove also facilitates increasing the area of ​​the first opening of the second channel, so that the gas can be quickly discharged from the electronic device.

[0023] In some possible implementations, the second groove is an arc-shaped groove, and the first opening is an arc-shaped opening.

[0024] This design allows the gas in the connecting channel to flow smoothly into the second channel under the guidance of the arc-shaped groove sidewall, reducing gas flow resistance and increasing the gas throughput of the pressure relief assembly. Simultaneously, it ensures a larger area for the first opening, which is an arc-shaped opening.

[0025] In some possible implementations, the first support member has a first channel communicating with the pressure relief chamber, and one side of the first channel is set as an inclined surface, which is connected to the groove surface of the second groove.

[0026] This design allows the gas entering the connecting channel from the first channel to flow smoothly into the first slit and / or the second slit, avoiding the problem of insufficient gas flow resistance and insufficient gas throughput caused by the step at the junction of the inclined surface and the groove surface of the second groove.

[0027] In some possible implementations, the pressure relief assembly includes a breathable membrane layer and a support layer; the outer periphery of the breathable membrane layer is bonded to the first support member, and the breathable membrane layer covers the pressure relief cavity; the support layer is disposed along a first direction on the side of the breathable membrane layer opposite to the first support member, and the support layer has a plurality of through holes, and the orthographic projection of the plurality of through holes on the first display screen is located within the orthographic projection of the pressure relief cavity on the first display screen.

[0028] The breathable membrane layer allows gas to pass through while preventing liquids or solids from passing through, so that the gas in the sealed cavity can communicate with the pressure relief cavity through the breathable membrane layer, while preventing external liquids or solids from entering the sealed cavity. The support layer covers the breathable membrane layer to protect it, and the through holes allow gas to pass through.

[0029] In some possible implementations, the electronic device includes a second display screen and a second frame assembly, wherein the second display screen and the battery cover are respectively disposed on both sides of the second frame assembly in the first direction;

[0030] The battery cover has an opening for clearance, and the first frame assembly is connected to the battery cover at the location of the opening for clearance.

[0031] The second display screen can be the main display screen of the electronic device, while the first display screen can be located on the back of the electronic device, serving as a secondary display screen. A pressure relief assembly is installed at the clearance location. The side of the pressure relief assembly along the first direction and closer to the first screen forms a pressure relief chamber, while the side along the first direction and closer to the second screen forms a closed chamber. That is, when the air pressure inside the closed chamber is too high, gas passes through the pressure relief assembly into the pressure relief chamber; conversely, when the external air pressure is too high, external gas can pass through the pressure relief assembly into the closed chamber, thus maintaining pressure balance inside and outside the closed chamber.

[0045] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0046] In electronic devices, pressure relief components are key components used to balance internal and external air pressure and release excess pressure. They are widely used in closed or semi-closed electronic devices such as smartphones, laptops, smart wearable devices (such as watches and headphones), and energy storage battery packs.

[0047] The electronic device contains a sealed cavity where components such as the motherboard and battery are installed. A pressure relief assembly is installed at the outlet of this cavity to facilitate gas exchange between the inside and outside. Typically, a separate opening is made on the electronic device, connecting to the side of the pressure relief assembly away from the sealed cavity. This allows gas inside the cavity to pass through the pressure relief assembly and then flow out through the opening to the outside of the electronic device; alternatively, it allows outside gas to enter the electronic device through the opening, then pass through the pressure relief assembly and enter the sealed cavity. Furthermore, the pressure relief assembly allows gas to pass through but not liquids or solids, such as water. Therefore, if water accidentally enters the electronic device, it cannot pass through the pressure relief assembly, thus preventing water from entering the components inside the sealed cavity. However, this separate opening on the electronic device affects its overall appearance and sophistication.

[0048] Therefore, this application provides an electronic device that ensures sufficient airflow while maintaining the overall appearance and sophistication of the device. For example, this electronic device can be a mobile phone, tablet, laptop, smart wearable device (such as a watch or earphone), energy storage battery pack, or other hermetically sealed or semi-hermetically sealed electronic device.

[0049] See Figure 1 and Figure 2 , Figure 1 This is a partial plan view of an electronic device provided in an embodiment of this application. Figure 2 yes Figure 1 A schematic diagram of a cross-section along the AA direction. An electronic device according to this application includes: a first frame assembly 100, a first display screen 200, a battery cover 400, and a pressure relief assembly 300.

[0050] The first frame assembly 100 includes a first frame 110 and a first support member 120 connected to each other. The first frame 110 surrounds the outer periphery of the first display screen 200. The first support member 120 is distributed with the first display screen 200 in a first direction, and the first support member 120 is used to support the first display screen 200. The first direction is perpendicular to the display surface of the first display screen 200, that is, the first direction can be the thickness direction of the electronic device.

[0051] Here, the first support member 120 is located at the bottom of the first display screen 200, which refers to the side opposite to the display side of the first display screen 200. The first support member 120 is used to support the first display screen 200 from the bottom, and the first frame 110 is used to support the first display screen 200 around its perimeter. Together, when the electronic device is subjected to external forces such as drops or collisions, the external forces can be dispersed through the first frame 110 and the first support member 120, avoiding stress concentration at the edges or weak areas of the first display screen 200, and significantly reducing the probability of core failures such as display screen breakage and leakage. The first support member 120 can be manufactured integrally with the first frame 110, or the two can be manufactured separately and then bonded together.

[0052] See Figure 3 and Figure 4 , Figure 3 and Figure 4 All Figure 2 The structural diagram at point B is shown. The battery cover 400 is positioned along the first direction on the side of the first frame 110 away from the first display screen 200; the first support member 120 has a pressure relief chamber 122 on the side away from the first display screen 200, and the pressure relief assembly 300 is connected to the side of the first support member 120 away from the first display screen 200 and covers the pressure relief chamber 122; wherein, the electronic device has a closed cavity, which is used to install components such as the motherboard and battery. The pressure relief assembly 300 serves as a gas exchange channel connecting the closed cavity to the outside. When the internal components heat up and cause the air pressure in the closed cavity to be too high, the gas passes through the pressure relief assembly 300 and enters the pressure relief chamber 122. When the external air pressure is too high, the external gas can enter the closed cavity through the pressure relief assembly 300 to maintain the air pressure balance inside and outside the closed cavity.

[0053] In the first direction, a first gap 111 is formed between the battery cover 400 and the first frame 110; in the direction parallel to the display surface of the first display screen 200, a second gap 113 is formed between the first display screen 200 and the first frame 110. The pressure relief chamber 122 communicates with both the first gap 111 and the second gap 113. With this configuration, when the air pressure inside the sealed cavity of the electronic device is high, gas passes through the pressure relief assembly 300 into the pressure relief chamber 122, and then exits through the pressure relief chamber 122 from the first gap 111 and / or the second gap 113 to the outside. Conversely, when the air pressure inside the sealed cavity of the electronic device is low, gas can enter the pressure relief chamber 122 from the first gap 111 and / or the second gap 113, and then pass through the pressure relief assembly 300 into the sealed cavity.

[0054] By setting the first gap 111 and the second gap 113, the airflow of the pressure relief assembly 300 can be increased, allowing the gas in the sealed cavity to be quickly discharged to the outside of the electronic device, preventing damage to components due to excessive pressure in the sealed cavity, or allowing gas to quickly enter the sealed cavity to quickly achieve pressure balance between the inside and outside of the sealed cavity. At the same time, when one gap is blocked due to assembly error, the airflow requirement of the pressure relief assembly 300 can still be guaranteed through the other gap. In addition, since the first gap 111 is located between the battery cover 400 and the first frame 110, and the second gap 113 is located between the first display screen 200 and the first frame 110, the airflow requirement of the pressure relief assembly 300 can be met by utilizing the assembly gaps between the battery cover 400 and the first frame 110 and the first display screen 200 and the first frame 110, thus eliminating the need for separate openings on the electronic device and not affecting the overall appearance and refinement of the electronic device.

[0055] In summary, both the first and second gaps are connected to the pressure relief chamber. When the air pressure inside the sealed cavity of the electronic device is high, gas passes through the pressure relief assembly into the pressure relief chamber, and then exits to the outside through the first and / or second gaps. Conversely, when the air pressure inside the sealed cavity of the electronic device is low, gas can enter the pressure relief chamber through the first and / or second gaps, and then pass through the pressure relief assembly into the sealed cavity. Furthermore, the design of the first and second gaps increases the gas flow rate of the pressure relief assembly, allowing gas in the sealed cavity to be quickly discharged to the outside of the electronic device, preventing damage to components due to excessive pressure inside the sealed cavity, or allowing gas to quickly enter the sealed cavity to achieve pressure balance between the inside and outside of the sealed cavity. Simultaneously, if one gap is blocked due to assembly errors, the other gap can still ensure the required gas flow rate of the pressure relief assembly. Furthermore, since the first gap is located between the battery cover and the first frame, and the second gap is located between the first display screen and the first frame, the airflow requirements of the pressure relief component are met by utilizing the assembly gap between the battery cover and the first frame and the assembly gap between the first display screen and the first frame, thus eliminating the need to make separate openings on the electronic device and not affecting the overall appearance and sophistication of the electronic device.

[0056] In one possible embodiment, see [reference] Figure 5 , Figure 5This is a schematic diagram of the rear of an electronic device according to an embodiment of this application. The first display screen 200 in the electronic device can be located on the back of the electronic device, and it can serve as a secondary display screen of the electronic device. In this case, the electronic device may further include: a second display screen and a second frame assembly 600, the second display screen and the battery cover 400 being respectively disposed on both sides of the second frame assembly 600 in a first direction; the battery cover 400 has an clearance opening 420, and the first frame assembly 100 is connected to the battery cover 400 at the location of the clearance opening 420.

[0057] The second display screen can be the main display screen of an electronic device. A second frame assembly 600 surrounds the outer periphery of the second display screen. The second display screen, battery cover 400, and second frame assembly 600 form a closed cavity for mounting components. A first frame 110 in the first frame assembly 100 surrounds the outer periphery of the first display screen 200. A first support member 120 supports the first display screen 200 and also secures it at the clearance opening 420. A pressure relief assembly 300 is installed at the clearance opening 420. The side of the pressure relief assembly 300 along the first direction and closer to the first display screen 200 is a pressure relief chamber 122, and the side along the first direction and closer to the second screen is a closed cavity. That is, when the air pressure inside the closed cavity is too high, gas passes through the pressure relief assembly 300 into the pressure relief chamber 122. When the external air pressure is too high, external gas can pass through the pressure relief assembly 300 into the closed cavity to maintain pressure balance inside and outside the closed cavity.

[0058] It should be noted that in scenarios where the electronic device includes both a first display screen 200 and a second display screen, the electronic device also includes a camera module 700, which can be installed inside the electronic device and can be exposed through the clearance opening 420 provided on the battery cover 400.

[0059] In some embodiments, the first display screen 200 has a through-hole corresponding to the camera module 700, through which the lens component in the camera module 700 can be exposed, allowing the camera module 700 to obtain ambient light for imaging.

[0060] In another possible embodiment, see [reference] Figure 6 , Figure 6This is a front view of an electronic device provided in an embodiment of this application. The first display screen 200 in the electronic device can be located on the front of the electronic device and can serve as the main display screen of the electronic device. In this case, the battery cover 400 and the first display screen 200 are respectively located on both sides of the first frame 110 along the first direction and in opposite positions. The battery cover 400, the first display screen 200, and the first frame 110 enclose a cavity structure. The cavity structure is divided into a pressure relief cavity 122 and a closed cavity. A pressure relief component 300 is provided between the pressure relief cavity 122 and the closed cavity. Components are provided in the closed cavity. The pressure relief cavity 122 communicates with the outside through a first gap 111 and / or a second gap 113.

[0061] The following description uses the first display screen 200 as an example of a secondary display screen for an electronic device.

[0062] See Figure 3 and Figure 4 In a direction parallel to the display surface of the first display screen 200, the battery cover 400 and the first support member 120 have a connecting channel 130. The connecting channel 130 is connected to the pressure relief chamber 122, the first gap 111, and the second gap 113.

[0063] In this embodiment, by providing a connecting channel 130, the first gap 111 can be connected to the pressure relief chamber 122, and the second gap 113 can also be connected to the pressure relief chamber 122. Even if one gap is blocked due to assembly error, pressure can still be relieved through the other gap. For example, when there is an assembly error between the first display screen 200 and the first frame 110 that causes the second gap 113 to be blocked, the first gap 111 is connected to the pressure relief chamber 122 through the connecting channel 130, thus allowing pressure to be relieved through the first gap 111. Alternatively, when there is an assembly error between the first frame 110 and the battery cover 400 that causes the first gap 111 to be blocked, the second gap 113 is connected to the pressure relief chamber 122 through the connecting channel 130, thus allowing pressure to be relieved through the second gap 113.

[0064] In some embodiments of this application, a first channel 121 is formed on the first support member 120. One end of the first channel 121 communicates with the pressure relief chamber 122, and the other end communicates with the connecting channel 130. Specifically, one end of the first channel 121 extends to communicate with the pressure relief chamber 122, and the other end passes through the first support member 120 to communicate with the connecting channel 130 between the first support member 120 and the battery cover 400 plate. Since the connecting channel 130 communicates with the first gap 111, the first gap 111 can be connected sequentially through the connecting channel 130, the first channel 121, and the pressure relief chamber 122. Similarly, since the connecting channel 130 communicates with the second gap 113, the second gap 113 can also be connected sequentially through the connecting channel 130, the first channel 121, and the pressure relief chamber 122.

[0065] For example, the extension direction of the first channel 121 is parallel to the display surface of the first display screen 200. Of course, considering the accuracy requirements in the actual production process or the mold demolding requirements, the extension direction of the first channel 121 can be made nearly parallel to the display surface of the first display screen 200.

[0066] In the first possible embodiment, see Figure 7 , Figure 7 This is a partial structural diagram of the battery cover provided in an embodiment of this application. The battery cover 400 has a first groove 410 on the side facing the first support member 120, and the first groove 410 and the side of the first support member 120 where the first channel 121 is provided enclose a communicating channel 130. The first gap 111 communicates with the first groove 410.

[0067] Compared to the method in related technologies where holes are directly drilled in the battery cover 400 or the first support member 120 to form a connecting channel 130, in this embodiment, only the first groove 410 needs to be drilled in the battery cover 400. The connecting channel 130 is formed by the first groove 410 and the first support member 120, which can greatly reduce the processing complexity and cost, while avoiding the structural risks caused by deep hole processing.

[0068] The shape of the first groove 410 can be a rectangular groove, an arc groove, a trapezoidal groove, etc., without much restriction. It should be emphasized that the opening of the first groove 410 also needs to ensure that the wall thickness of the battery cover 400 meets certain requirements, so that the battery cover 400 has a certain supporting strength while maximizing the volume of the first groove 410, thereby increasing the cross-sectional area of ​​the connecting channel 130 along the extension direction to increase the air flow.

[0069] See Figure 8 , Figure 8This is a partial structural diagram of the electronic device provided in an embodiment of this application. The first frame 110 has a notch 114 on the side facing the battery cover 400, such that when the first frame 110 is mounted along a first direction on the side of the battery cover 400 facing away from the first display screen 200, a first gap 111 is formed between the first frame 110 and the battery cover 400. Of course, the notch 114 can also be formed on the side of the battery cover 400 facing the first frame 110.

[0070] In order to increase the air flow, the notch 114 can be set as an elongated notch, that is, the first gap 111 is an elongated gap, so as to increase the air flow of the first gap 111.

[0071] See Figures 4-6 The first support member 120 has a first channel 121 that communicates with the pressure relief chamber 122. The side wall of the first channel 121 is set as an inclined surface 123. The end of the first channel 121 away from the pressure relief chamber 122 passes through the inclined surface 123. The inclined surface 123 and the first groove 410 enclose a connecting channel 130, thereby realizing the connection between the first channel 121 and the connecting channel 130.

[0072] The first groove 410 has a sidewall 411 inclined away from the inclined surface 123 and a bottom wall 412 located at one end of the sidewall 411. The bottom wall 412 is sealed to the first support member 120 by a sealing gasket. The sidewall 411 and the inclined surface 123 are spaced apart to form a connecting channel 130. Along the direction from the bottom wall 412 to the first gap 111, the distance between the sidewall 411 and the inclined surface 123 gradually increases, so that the size of the connecting channel 130 near the first gap 111 is larger than the size away from the first gap 111, so that gas can quickly flow from the first channel 121 through the connecting channel 130 to the first gap 111.

[0073] In a second possible embodiment, the first support member has a first groove on the side facing the battery cover, and the end of the first channel away from the pressure relief chamber is connected to the first groove. The first groove and the battery cover together form a connecting channel, which can also form a connecting channel, and at the same time, one end of the first channel is connected to the connecting channel.

[0074] In a third possible embodiment, the side of the battery cover facing the first support member and the side of the first support member facing the battery cover each have a first groove. The end of the first channel away from the pressure relief chamber is connected to the first groove. The openings of the two first grooves are opposite each other. When the battery cover is connected to the first support member, the two first grooves enclose a connecting channel.

[0075] See Figure 3 and Figure 4A second channel 112 is provided between the first frame 110 and the first support member 120. One end of the second channel 112 is connected to the connecting channel 130, and the other end is connected to the second gap 113. That is, the connecting channel 130 is connected to the second gap 113 through the second channel 112. In this way, the pressure relief chamber 122 is connected to the second gap 113 through the first channel 121, the connecting channel 130, the second channel 112, and the second gap 113 in sequence. Compared with directly opening a hole in the first frame 110 or the first support member 120 to form the second channel 112, in this embodiment, forming the second channel 112 between the first frame 110 and the first support member 120 can significantly reduce the processing complexity and cost, while avoiding the structural risks caused by deep hole processing.

[0076] In the first possible embodiment, see Figure 9 , Figure 9 This is a partial structural diagram of the first support member in the electronic device provided in the embodiments of this application. The first support member 120 has a fourth groove 124 on the side wall near the first frame 110 along the first direction. The fourth groove 124 and the inner wall of the first frame 110 form a second channel 112 so that the connecting channel 130 and the second gap 113 can be connected through the second channel 112.

[0077] In a second possible embodiment, the first frame has a fourth groove on the side wall near the first support member along the first direction. The fourth groove and the outer wall of the first support member form a second channel so that the connecting channel and the second gap can be connected through the second channel.

[0078] In a third possible embodiment, the first support member has a fourth groove on the side wall of the first frame along the first direction near the first frame and the first frame has a fourth groove on the side wall of the first support member along the first direction. The openings of the two fourth grooves are opposite to each other and the two fourth grooves are used to enclose a second channel so that the connecting channel and the second gap can be connected through the second channel.

[0079] See Figure 4 and Figure 10 , Figure 10This is a schematic diagram of the electronic device provided in this application after removing part of the first display screen. The area of ​​the first opening 112a, which connects the second channel 112 and the connecting channel 130, is larger than the area of ​​the second opening 112b, which connects the second channel 112 and the second gap 113. The second channel 112 extends along a first direction. The larger area of ​​the first opening 112a allows for rapid reception of high-pressure gas flowing in from the connecting channel 130, preventing gas congestion caused by the narrowness of the second gap 113. Simultaneously, the larger area of ​​the first opening 112a compared to the second opening 112b, according to fluid dynamics principles, causes an increase in flow velocity due to space contraction when gas enters from the larger first opening 112a and flows towards the smaller second opening 112b. This accelerated gas can then pass through the second opening 112b more quickly into the second gap 113, ultimately exiting the electronic device quickly and reducing the risk of high-pressure damage to components.

[0080] See Figure 4 and Figure 11 , Figure 11 yes Figure 2 In the structural schematic diagram at point B, in the first direction, the first frame assembly 100 has a second groove 140 on the side facing the battery cover 400. The second groove 140 is connected to the connecting channel 130. The first opening 112a distributed at one end of the second channel 112 is located on the groove surface of the second groove 140.

[0081] In this embodiment, the second groove 140 is used to further increase the volume of the connecting channel 130 so as to quickly balance the internal and external pressure difference. At the same time, the second groove 140 also facilitates increasing the area of ​​the first opening 112a of the second channel 112, so that the gas can be quickly discharged from the electronic device.

[0082] The second groove 140 is an arc-shaped groove, and the first opening 112a is an arc-shaped opening. This allows the gas in the connecting channel 130 to flow smoothly into the second channel 112 under the guidance of the side wall 411 of the arc-shaped groove, reducing gas flow resistance and increasing the gas throughput of the pressure relief assembly 300. At the same time, it ensures that the area of ​​the first opening 112a, which is an arc-shaped opening, is relatively large.

[0083] The first support member 120 has a first channel 121 communicating with the pressure relief chamber 122. One side of the first channel 121 of the first support member 120 is a slope 123, which is connected to the groove surface of the second groove 140. The connection between the slope 123 on the side of the first channel 121 and the groove surface of the second groove 140 allows gas entering the connecting channel 130 from the first channel 121 to flow smoothly into the first gap 111 and / or the second gap 113. This avoids the problem of high gas flow resistance and insufficient gas throughput caused by a step at the junction of the slope 123 and the groove surface of the second groove 140.

[0084] See Figure 12 , Figure 12 This is an exploded structural diagram of the pressure relief assembly provided in this application embodiment. The pressure relief assembly 300 includes a breathable membrane layer 320 and a support layer 340. The outer periphery of the breathable membrane layer 320 is bonded to the first support member 120, and the breathable membrane layer 320 covers the pressure relief cavity 122. The support layer 340 is disposed along a first direction on the side of the breathable membrane layer 320 away from the first support member 120. The support layer 340 has a plurality of through holes 341, and the projection of the plurality of through holes 341 on the first display screen 200 is located within the projection of the pressure relief cavity 122 on the first display screen 200.

[0085] In this embodiment, the breathable membrane layer 320 typically employs a microporous structure membrane, such as a PTFE breathable membrane or an ePTFE membrane, which possesses the characteristic of allowing gas to pass through while preventing liquids or solids from passing through. When the pressure inside the sealed cavity suddenly increases, the high-pressure gas can overcome the microporous resistance of the breathable membrane layer 320 and quickly flow through the breathable membrane layer 320 to the pressure relief chamber 122 side, and then be discharged outside the electronic device through the first gap 111 and / or the second gap 113, thus achieving pressure relief. When the pressure inside the sealed cavity is lower than that outside, outside gas can also enter the sealed cavity through the breathable membrane layer 320 in the opposite direction, balancing the internal and external pressures and preventing problems such as screen edge warping and battery cover 400 denting caused by pressure differences. The support layer 340 covers the breathable membrane layer 320 to protect it, and the through-hole 341 allows gas to pass through.

[0086] For example, the area of ​​the breathable membrane layer 320 is larger than the opening area of ​​the pressure relief chamber 122. The outer periphery of the breathable membrane layer 320 is coated with a first adhesive layer 310, so that the breathable membrane layer 320 is bonded to the first support member 120 through the first adhesive layer 310 and covers the pressure relief chamber 122. A second adhesive layer 330 is placed between the support layer 340 and the breathable membrane layer 320. The second adhesive layer 330 has at least one breathable area. Taking three as an example, all three breathable areas are located within the opening area of ​​the pressure relief chamber 122. The support layer 340 also has multiple opening areas corresponding to the breathable areas, and each opening area has multiple through holes 341. This arrangement allows gas in the closed chamber to pass through the breathable membrane layer 320, enter the opening area, and enter the pressure relief chamber 122 through the multiple through holes 341.

[0087] The support layer 340 is used to protect the breathable membrane layer 320. The support layer 340 can be made of metal and is connected to the first support member 120 by screws.

[0088] In summary, both the first and second gaps are connected to the pressure relief chamber. When the air pressure inside the sealed cavity of the electronic device is high, gas passes through the pressure relief assembly into the pressure relief chamber, and then exits to the outside through the first and / or second gaps. Conversely, when the air pressure inside the sealed cavity of the electronic device is low, gas can enter the pressure relief chamber through the first and / or second gaps, and then pass through the pressure relief assembly into the sealed cavity. Furthermore, the design of the first and second gaps increases the gas flow rate of the pressure relief assembly, allowing gas in the sealed cavity to be quickly discharged to the outside of the electronic device, preventing damage to components due to excessive pressure inside the sealed cavity, or allowing gas to quickly enter the sealed cavity to achieve pressure balance between the inside and outside of the sealed cavity. Simultaneously, if one gap is blocked due to assembly errors, the other gap can still ensure the required gas flow rate of the pressure relief assembly. Furthermore, since the first gap is located between the battery cover and the first frame, and the second gap is located between the first display screen and the first frame, the airflow requirements of the pressure relief component are met by utilizing the assembly gap between the battery cover and the first frame and the assembly gap between the first display screen and the first frame, thus eliminating the need to make separate openings on the electronic device and not affecting the overall appearance and sophistication of the electronic device.

[0089] It should be noted that the dimensions of layers and regions may be exaggerated in the accompanying drawings for clarity. Furthermore, it is understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element, or there may be intermediate layers. Additionally, it is understood that when an element or layer is referred to as being "below" another element or layer, it can be directly below the other element, or there may be more than one intermediate layer or element. Furthermore, it is also understood that when a layer or element is referred to as being "between" two layers or two elements, it can be the only layer between the two layers or two elements, or there may be more than one intermediate layer or element. Similar reference numerals throughout indicate similar elements.
