Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an electronic device. Background Technology

[0002] In related technologies, the frame of electronic devices usually has an air pressure balancing hole. The function of the air pressure balancing hole is to balance the air pressure inside and outside the electronic device, so as to prevent abnormal noises when the electronic device plays music. The air pressure balancing hole is connected to the inside of the electronic device, and a waterproof and breathable membrane is attached to the air pressure balancing hole to ensure that the channel can be ventilated but water cannot enter.

[0003] However, when electronic devices are subjected to continuous water flow, the water flow will continuously and forcefully impact the waterproof and breathable membrane, causing the waterproof and breathable membrane to detach, thereby affecting the waterproof performance of the electronic devices. Summary of the Invention

[0004] The purpose of this application is to provide an electronic device that can solve the technical problem of poor waterproof performance of electronic devices with openings.

[0005] This application provides an electronic device, including:

[0006] The frame has a receiving space, and the frame is also provided with a through hole and a first channel. The first end of the first channel is connected to the through hole, and the second end of the first channel is connected to the receiving space.

[0007] A flow guiding structure is disposed in the first channel. The flow guiding structure includes a spiral skirt, which includes at least two layers of skirts. The at least two layers of skirts are stacked along the first direction, and the projection of the at least two layers of skirts on the first plane coincides with the projection of the through hole on the first plane.

[0008] Wherein, the first direction is the direction from the first end to the second end of the first channel, and the first plane is a plane perpendicular to the first direction.

[0009] In this embodiment of the application, the electronic device includes a frame and a flow guiding structure fixed to the frame. The frame has a receiving space for accommodating other components inside the electronic device. The frame is also provided with a through hole and a first channel. The first end of the first channel is connected to the through hole, and the second end of the first channel is connected to the receiving space.

[0010] The flow guiding structure is set in the first channel, and the direction from the first end to the second end of the first channel is the first direction.

[0011] The flow guiding structure includes a spiral skirt, which comprises at least two layers of skirts stacked along a first direction, forming a first plane perpendicular to the first direction. The at least two layers of skirts form a first projection on the first plane, and the through hole forms a second projection on the first plane. The first projection and the second projection coincide, thereby allowing the flow guiding structure to fully block the through hole. This ensures that liquid entering the first channel through the through hole is guided by the flow guiding structure, thereby reducing the impact force of the liquid, reducing the impact of liquid impact on the internal components of the electronic device, and improving the waterproof performance of the electronic device.

[0038] The following is combined Figures 1 to 20 An electronic device 1 according to an embodiment of this application is described.

[0039] like Figure 1 , Figure 2 and Figure 3As shown, this application embodiment provides an electronic device 1, including: a frame 11, the frame 11 having a receiving space 111, the frame 11 also having a through hole 112 and a first channel 113, the first end of the first channel 113 being connected to the through hole 112, the second end of the first channel 113 being connected to the receiving space 111, and a flow guiding structure 12, the flow guiding structure 12 being disposed in the first channel 113, the flow guiding structure 12 including a spiral skirt 122, the spiral skirt 122 including at least two layers of skirt 122, the at least two layers of skirt 122 being stacked along a first direction OX, the projection of the at least two layers of skirt 122 on a first plane coinciding with the projection of the through hole 112 on a first plane; wherein, the first direction OX is the direction from the first end to the second end of the first channel 113, and the first plane is a plane perpendicular to the first direction OX.

[0040] In this embodiment of the application, the electronic device 1 includes a frame 11 and a flow guiding structure 12 fixed to the frame 11. The frame 11 has a receiving space 111 for accommodating other components inside the electronic device 1. The frame 11 is also provided with a through hole 112 and a first channel 113. The first end of the first channel 113 is connected to the through hole 112, and the second end of the first channel 113 is connected to the receiving space 111.

[0041] The flow guiding structure 12 is disposed in the first channel 113, and the direction from the first end to the second end of the first channel 113 is the first direction OX.

[0042] The flow guiding structure 12 includes a spiral skirt 122, which includes at least two layers of skirt 122. The at least two layers of skirt 122 are stacked along the first direction OX and form a first plane perpendicular to the first direction OX. The at least two layers of skirt 122 form a first projection on the first plane, and the through hole 112 forms a second projection on the first plane. The first projection and the second projection coincide, so that the flow guiding structure 12 can fully block the through hole 112, so that the liquid entering the first channel 113 through the through hole 112 will be guided by the flow guiding structure 12, thereby reducing the impact force of the liquid, reducing the impact of liquid impact on the internal components of the electronic device 1, and improving the waterproof performance of the electronic device 1.

[0043] The spiral skirt 121 also guides the liquid in a spiral manner, and the spiral guidance can greatly consume the liquid's energy by changing the liquid's flow direction at any time, thereby reducing the impact force of the liquid entering the first channel 113.

[0044] Among them, such as Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10As shown, the spiral structure of the spiral skirt 121 extends continuously. When a portion of the skirt 122 overlaps with a previous skirt 122, the overlapping position becomes the next layer of skirt 122. That is, the first layer of skirt 122 is a 360-degree loop. The skirt 122 from 360 degrees to 720 degrees is the second layer of skirt 122, and similarly, the skirt 122 from 720 degrees to 1080 degrees is the third layer of skirt 122, and so on. The final layer of skirt 122 may not necessarily loop 360 degrees. Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10 The dashed line in the middle represents the boundary between the two layers of skirt hem 122.

[0045] like Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 As shown, the frame 11 is provided with a through hole 112 and a first channel 113. The through hole 112 faces the outside of the frame 11, and the first channel 113 faces the inside of the frame 11.

[0046] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, in one possible implementation, the flow guiding structure 12 further includes: a columnar portion 123, a spiral skirt 121 disposed on the periphery of the columnar portion 123, and the spiral skirt 121 extending spirally along the axial direction of the columnar portion 123.

[0047] Specifically, the flow guiding structure 12 includes a columnar portion 123 and a spiral skirt 121, with the spiral skirt 121 disposed around the periphery of the columnar portion 123. Furthermore, the spiral skirt 121 extends spirally along the axial direction of the columnar portion 123. The columnar portion 123 fixes the shape of the spiral skirt 121, reducing the possibility of deformation. Additionally, the columnar portion 123 effectively reduces the possibility of leakage at the center of the spiral skirt 121, thus improving the flow guiding effect of the flow guiding structure 12.

[0048] The flow guiding structure 12 can be made of metal, with a cylindrical or prismatic columnar part 123 in the middle, and a spiral skirt 121 arranged around the periphery of the columnar part 123.

[0049] like Figure 3 , Figure 9 , Figure 10 and Figure 11 As shown, in one possible implementation, the radial OY dimension D3 of the through hole 112 is greater than the radial OY dimension D2 of the first channel 113. The projection of the skirt 122 that is away from the receiving space 111 in the first plane coincides with the projection of the through hole 112 in the first plane. The skirt 122 that is away from the receiving space 111 in the at least two skirts 122 is disposed in the through hole 112. The radial OY dimension D1 of the skirt 122 that is away from the receiving space 111 in the at least two skirts 122 is greater than or equal to the radial OY dimension D3 of the through hole 112.

[0050] Specifically, the radial OY dimension D3 of the through hole 112 is larger than the radial OY dimension D4 of the first channel 113. At least one of the two skirts 122, which is away from the receiving space 111, is disposed in the through hole 112. Thus, the flow guiding structure 12 can be installed in the direction from the channel to the first channel 113. After installation, since the radial OY dimension D4 of the first channel 113 is smaller, the flow guiding structure 12 is less likely to move in the direction of the first channel 113, thereby improving the stability of the flow guiding structure 12.

[0051] The projection of the skirt 122 that is away from the receiving space 111 on the first plane coincides with the projection of the through hole 112 on the first plane. That is, the skirt 122 that is away from the receiving space 111 can cover the entire through hole 112, thereby achieving effective guidance of the liquid entering the channel.

[0052] At least two skirts 122 are disposed in the through hole 112, one of which is away from the receiving space 111. The skirt 122 away from the receiving space 111 is the skirt 122 closest to the outside of the electronic device 1, thereby effectively reducing the number of layers and volume of the spiral skirt 121.

[0053] At least two skirts 122, the radial OY dimension D1 of the skirt 122 that is away from the receiving space 111 is greater than or equal to the radial OY dimension D3 of the through hole 112, thereby improving the reliability of the spiral skirt 121 in blocking the through hole 112.

[0054] The radial OY dimension D2 of the skirts 122 other than the one skirt 122 facing away from the receiving space 111 can be 1mm to 2mm, depending on the appearance requirements. The frame 11 of the electronic device 1 has many holes, and the overall size needs to be kept harmonious. Apart from the one skirt 122 facing away from the receiving space 111, the other skirts 122 can be arranged in one to two more circles. That is, the at least two skirts 122 can include two or three skirts 122. This reduces the complexity of the structure while improving the consumption of liquid energy, and can also take into account the gas flow of the receiving space 111 and the external space of the electronic device 1.

[0055] The portion of the through hole 112 near the first channel 113 has a stepped surface, which is spiral-shaped, causing the through hole 112 to form a spiral rotation. After the electronic device 1 is assembled, at least one of the two skirts 122 that is away from the receiving space 111 and the stepped surface are fixed together by means of heat pressing or double-sided adhesive.

[0056] like Figure 3 , Figure 9 , Figure 10 and Figure 11 As shown, in one possible implementation, the other skirt layers 122 of the at least two skirt layers 122 are disposed within the first channel 113. The radial OY dimension D1 of the skirt layer 122 that is away from the receiving space 111 is greater than the radial OY dimension D2 of the other skirt layers 122 of the at least two skirt layers 122, and the radial OY dimension D2 of the other skirt layers 122 of the at least two skirt layers 122 is greater than or equal to the radial OY dimension D3 of the first channel 113.

[0057] Specifically, the other skirts 122 of the skirt 122 that are away from the receiving space 111 are disposed in the first channel 113. The radial OY dimension D1 of the skirt 122 that is away from the receiving space 111 is greater than the radial OY dimension D2 of the other skirts 122. That is, the radial OY dimension D1 of the skirt 122 that is away from the receiving space 111 in the spiral skirt 121 is the largest, so that the flow guiding structure 12 can be conveniently installed in the frame 11.

[0058] The radial OY dimension D2 of the other two skirt layers 122 is greater than or equal to the radial OY dimension D4 of the first channel 113, thereby improving the reliability of the spiral skirt 121 in blocking the first channel 113.

[0059] like Figure 2 , Figure 3 , Figure 9 , Figure 10 and Figure 11As shown, in one possible implementation, the first channel 113 is a spiral first channel 113, which is spirally engaged with other layers of skirts 122 in at least two layers of skirts 122.

[0060] The first channel 113 is a spiral first channel 113, which is spirally engaged with other layers of skirt 122 in at least two layers of skirt 122. The spiral first channel 113 and other layers of skirt 122 in at least two layers of skirt 122 are spirally engaged, which makes the flow channel formed by the flow guiding structure 12 and the first channel 113 more airtight and reduces the possibility of liquid overflowing between the flow guiding structure 12 and the first channel 113.

[0061] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, in one possible implementation, the radial OY dimension D2 of the other skirt layers 122 in at least two skirt layers 122 gradually decreases.

[0062] Specifically, the radial OY dimension D2 of the other skirt layers 122 in at least two skirt layers 122 gradually decreases. The gradually decreasing skirt layers 122 can gradually reduce the flow channel formed by the flow guiding structure 12 and the first channel 113, thereby increasing the consumption of the impact force of the liquid and further improving the waterproof performance of the electronic device 1.

[0063] Among them, the radial OY dimension D2 of other skirt layers 122 in at least two skirt layers 122 gradually decreases. This can be either the radial OY dimension D2 of the same skirt layer 122 gradually decreases, or the radial OY dimension D2 of the same skirt layer 122 is the same, and the radial OY dimension D2 of different skirt layers 122 gradually decreases.

[0064] Among them, at least two skirt layers 122 are closely connected to the first channel 113.

[0065] like Figure 1 , Figure 2 , Figure 13 and Figure 14As shown, in one possible implementation, the electronic device 1 further includes: a display component 13; a frame 11 including a frame 115 and a shelf 116, the frame 115 surrounding the shelf 116 and the shelf 116 being connected to the frame 115; a cover plate 14, the cover plate 14, the display component 13 and the shelf 116 being stacked, and the cover plate 14 and the display component 13 being located on both sides of the frame 115 and both being connected to the frame 115, the frame 115, the display component 13 and the cover plate 14 enclosing a receiving space 111, and a gap 15 being provided at the connection between the frame 115 and the cover plate 14; a second channel 117 is also provided in the shelf 116, the first end of the second channel 117 communicating with the first channel 113, and the second end of the second channel 117 communicating with the gap 15.

[0066] Specifically, the electronic device 1 also includes a display component 13 and a cover plate 14. The frame 11 includes a connected frame 115 and a frame plate 116. The frame 115 surrounds the frame plate 116. The cover plate 14, the display component 13 and the frame plate 116 are stacked. The cover plate 14 and the display component 13 are located on both sides of the frame plate 116 and on both sides of the frame 115, so that the display component 13, the frame 115 and the cover plate 14 can enclose a space, that is, a receiving space 111, in which other components of the electronic device 1 can be installed.

[0067] The frame 115 and the cover plate 14 are connected by a gap 15. The frame plate 116 is provided with a second channel 117. The first end of the second channel 117 is connected to the first channel 113, and the second end of the second channel 117 is connected to the gap 15, thereby achieving air pressure balance between the accommodating space 111 and the outside of the electronic device 1.

[0068] Furthermore, after liquid enters the first channel 113, it can be discharged from the electronic device 1 through the second channel 117 and the gap 15, thereby providing a drainage channel for the first channel 113. In the event that liquid continuously enters the first channel 113, at least some of the liquid can be discharged through the second channel 117 and the gap 15, thereby reducing the pressure in the first channel 113, reducing the possibility of liquid entering the containment space 111, and further improving the waterproof performance of the electronic device 1.

[0069] The second channel 117 is roughly rectangular in shape at the second end facing the cover plate 14. The cover plate 14 covers the second end of the second channel 117. After the entire machine is assembled, the second channel 117 is covered by the cover plate 14 and is not visible from the outside.

[0070] The first end of the second channel 117 faces the flow guide structure 12 and is positioned opposite to the spiral skirt 121. The liquid guided by the spiral skirt 121 can directly enter the second channel 117 under the action of centrifugal force, and the liquid in the first channel 113 can be quickly discharged through the second channel 117.

[0071] like Figure 2 and Figure 3 As shown, in one possible implementation, a third channel 118 is also provided in the frame 116. The first end of the third channel 118 is connected to the first channel 113, and the second end of the third channel 118 is connected to the display component 13. The electronic device 1 also includes a waterproof and breathable membrane 16, which is sealed at the second end of the third channel 118.

[0072] Specifically, the mounting plate 116 is also provided with a third channel 118. The first end of the third channel 118 is connected to the first channel 113, and the second end of the third channel 118 is connected to a portion of the accommodating space 111 on one side of the display component 13, thereby achieving the purpose of balancing the air pressure inside and outside the electronic device 1, sending information to the outside of the electronic device 1, or receiving information from the outside of the electronic device 1.

[0073] The electronic device 1 also includes a waterproof and breathable membrane 16, which is sealed at the second end of the third channel 118, so that gas can flow between the outside and inside of the electronic device 1 through the through hole 112, the first channel 113 and the third channel 118. At the same time, it can also block liquid, thereby improving the waterproof performance of the electronic device 1 while satisfying its response function.

[0074] The waterproof and breathable membrane 16 and the frame 11 can be fixed by means of adhesive bonding or other methods.

[0075] That is, the electronic device 1 includes a frame 11, a cover plate 14, a display component 13, and a waterproof and breathable membrane 16. The frame 11 includes a frame 115 and a frame plate 116. The cover plate 14 and the display component 13 are respectively disposed on opposite sides of the frame plate 116. Furthermore, the cover plate 14 and the display component 13 are respectively connected to opposite sides of the frame 115. The frame 115, the cover, and the display component 13 enclose an accommodating space 111, which is used to install other components.

[0076] Furthermore, airflow can enter and exit the accommodating space 111 and the external space of the electronic device 1 through the through hole 112, the first channel 113, and the third channel 118, achieving the effect of balancing air pressure and receiving or transmitting information. After entering the through hole 112, the liquid is first blocked by the flow guiding structure 12, which reduces the impact force and flow velocity of the liquid. Then, it enters the first channel 113, and some of the liquid will enter the second channel 117 and the gap 15 to be discharged from the electronic device 1, thereby reducing the pressure of the liquid on the waterproof and breathable membrane 16 for the second time. At most, only a small amount of liquid will act on the waterproof and breathable membrane 16, thus greatly reducing the impact of the liquid on the waterproof and breathable membrane 16, improving the reliability of the waterproof and breathable membrane 16, reducing the possibility of the waterproof and breathable membrane 16 being detached by liquid impact, and improving the waterproof performance of the electronic device 1.

[0077] like Figure 2 As shown, in one possible implementation, a sealing structure 17 is provided between the cover plate 14 and the frame plate 116, and the gap 15 is located on the outside of the sealing structure 17.

[0078] Specifically, a sealing structure 17 is provided between the cover plate 14 and the frame plate 116, thereby further improving the waterproof performance of the electronic device 1.

[0079] The gap 15 is located outside the sealing structure 17, meaning that the liquid discharged from the electronic device 1 through the gap 15 will not affect the containment space 111.

[0080] The sealing structure 17 can be a sealant or foam, etc.

[0081] like Figure 2 As shown, in one possible implementation, the electronic device 1 further includes a circuit board 18 disposed within a portion of the receiving space 111 enclosed by the frame plate 116 and the cover plate 14.

[0082] Specifically, the electronic device 1 also includes a circuit board 18 within the accommodating space 111. The circuit board 18 is located within the portion of the accommodating space 111 enclosed by the frame 116 and the cover plate 14, thereby enabling the frame 116 to effectively support the display component 13 and the circuit board 18.

[0083] As one possible implementation, the flow guiding structure 12 and the frame 11 can be connected by means of bonding or welding.

[0084] Optionally, at least one skirt 122 on each side that is opposite to the receiving space 111 and the frame 11 may be connected by means of adhesive or welding.

[0085] Of course, in other embodiments of this application, the frame 11 and the flow guiding structure 12 may also be manufactured as a single piece by means of printing or injection molding.

[0086] like Figure 2 and Figure 18 As shown, in one possible implementation, the through hole 112, the first channel 113 and the second channel 117 can form at least one of the sound outlet, the sound receiver and the air pressure balance hole.

[0087] Among them, such as Figure 19 and Figure 20 As shown, when the electronic device 1 is subjected to a waterproof test, the test device 2 needs to spray water onto the electronic device 1 from multiple angles through a nozzle. When the electronic device 1 provided in this application is subjected to water spray, the waterproof and breathable membrane 16 will not be affected by the water flow and will not fall off or be damaged.

[0088] This application adopts a "dredging rather than blocking" approach, abandoning the water-blocking concept used in related technologies and instead using a method to divert the water flow faced by the electronic device 1. Compared to previous "water-blocking" solutions, this application embodiment simply adds a guiding structure 12 and a second channel 117 to the original channel to achieve liquid diversion and diversion, without simply lengthening the channel or adding extra space. Compared to water blocking, diversion has a stronger ability to withstand continuous water flow impact and better protective performance. The diversion hole is located below the cover and does not affect the appearance.

[0089] like Figure 2 and Figure 3 As shown, Figure 2 and Figure 3 The middle arrow indicates the direction of water flow. When the liquid rushes in from the bottom of the frame 11, it is constrained by the flow guiding structure 12 and the water flow will be constrained to move in a spiral direction. On the last turn, the liquid will encounter the second channel 117 of the frame 11 towards the cover. The spiraling liquid has centrifugal force. Under the action of centrifugal force, the liquid will be thrown into the second channel 117, reducing the possibility of the liquid directly entering the third channel 118, or even no liquid entering the third channel 118, reducing the possibility of the liquid breaking through the waterproof and breathable membrane 16 or the waterproof and breathable membrane 16 falling off.

[0090] The second channel 117 is connected to the lower part of the cover plate 14 and is located outside the sealing structure 17. The location of the second channel 117 has a large space. The space outside the cover plate 14 and the sealing structure 17 can accommodate water ingress. After the liquid impact ends, the gap 15 between the cover plate 14 and the frame 11 allows the liquid to flow out of the electronic device 1.

[0091] When faced with liquid impact, the flow guiding structure 12 changes the direction of liquid flow through the spiral skirt 121, diverting the liquid to the outside of the electronic device 1, thus preventing the thin waterproof and breathable membrane 16 from bearing all the liquid pressure.

[0092] This application embodiment improves the waterproof capability of the channel location through the "hydrophobic" design. Firstly, its performance is better than the "water-blocking" solution. Moreover, the added feature does not occupy extra space, and the design implementation has little impact on the whole machine. The second channel 117 is hidden under the cover plate 14, and the liquid is discharged through the gap 15 between the cover plate 14 and the frame 11 without affecting the appearance.

[0093] Electronic device 1 can be a terminal or other devices besides a terminal. For example, electronic device 1 can be a mobile phone, tablet computer, laptop computer, handheld computer, music playback device, private network communication terminal equipment (such as walkie-talkie), mobile internet device (MID), augmented reality / virtual reality / mixed reality device, robot, drone, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc. The embodiments of this application do not specifically limit it.

In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0095] Although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the claims and their equivalents.
