Description

Technical Field

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

[0002] At present, mobile phones, computers and other electronic devices have become inseparable from our lives, greatly facilitating people's lives. The display screen and the housing are two important components of electronic devices. In the related art, in order to achieve a fixed connection between the display screen and the housing, a boss is generally provided on the inner peripheral wall of the housing frame, and the transparent cover plate of the display screen is supported on the boss. A colloid is provided between the transparent cover plate and the boss to bond the transparent cover plate to the boss.

[0003] As people have higher and higher requirements for the screen appearance of electronic devices, the higher the screen-to-body ratio, the better the visual effect, so narrow bezel and full-screen design have become a development trend. In order to increase the screen-to-body ratio of electronic devices, the width of the boss is getting narrower and narrower, resulting in a narrower bonding width between the boss and the transparent cover. As a result, it is difficult for the colloid to be evenly pressed between the boss and the transparent cover, and there will be a sealing gap between the boss and the transparent cover, resulting in sealing failure.

[0004] It is understandable that there will inevitably be a gap between the display screen and the frame of the shell, and external grease and water stains (such as user sweat, etc.) are likely to accumulate in the gap. At this time, grease and water stains are likely to enter the interior of the display screen through the sealing gap between the boss and the transparent cover plate and corrode the display screen, thereby causing yellow spots to appear on the display screen and affecting the display effect of the display screen. Summary of the invention

[0005] The present application provides a housing and an electronic device, which can guide grease and water stains in the gap between a display screen and a frame portion of the housing to the sound-through opening in a timely manner through a guide groove, thereby preventing the grease and water stains from entering the interior of the display screen and corroding the display screen.

[0006] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0007] In a first aspect, a shell is provided, which includes: a frame portion, a boss is provided on the inner peripheral wall of the frame portion, the boss extends along the circumference of the frame portion, the boss has a bearing surface, and the bearing surface is used to bond a transparent cover plate of a display screen; wherein the boss has a sound-passing opening, and the boss is provided with a guide groove with an open front side, the guide groove and the bearing surface are located on the same wall surface of the boss, and one end of the guide groove passes through the side wall surface of the boss facing the sound-passing opening.

[0008] In this way, after the grease and water stains from the outside fall onto the wall surface where the bearing surface of the boss is located through the gap between the light-transmitting cover plate and the frame portion, they can be gathered in the guide groove. Since the first end of the guide groove passes through the side wall surface of the boss facing the sound-passing opening, that is, the guide groove is connected with the sound-passing opening through its first end, the grease and water stains gathered in the guide groove can be promptly guided to the sound-passing opening through the first end of the guide groove, thereby preventing the grease and water stains from accumulating on the wall surface of the boss where the bearing surface is located, and further preventing the grease and water stains from passing through the sealing gap between the bearing surface and the light-transmitting cover plate and entering the interior of the display screen to corrode the display screen.

[0009] In a possible implementation of the first aspect, the guide groove is located on the side of the bearing surface facing the frame portion. In this way, the guide groove can be directly opposite to the gap between the frame portion and the light-transmitting cover plate, or be close to the gap, which makes it easier for water stains and grease to enter the guide groove, so that the water stains and grease are more promptly guided out of the boss wall where the bearing surface is located.

[0010] In a possible implementation of the first aspect, the end of the guide groove that passes through the boss and faces the side wall of the sound-passing opening is the first end, and the end of the guide groove that is away from the first end is the second end. In the direction from the second end toward the first end, the bottom wall of the guide groove extends obliquely in the direction away from the front side. In this way, in the direction from the second end toward the first end, the bottom wall of the guide groove extends obliquely along the direction of gravity to which the grease and water stains are subjected. As a result, the grease and water stains collected in the guide groove can flow from the second end to the first end more quickly and smoothly, and then be guided from the first end to the sound-passing opening.

[0011] In a possible implementation of the first aspect, a height difference ΔH between the bottom wall of the second end and the bottom wall of the first end is greater than or equal to 0.3 mm. In this way, the bottom wall of the guide groove has a larger inclination angle, so that the guide groove has a better guiding effect on grease and water stains, and the grease and water stains in the guide groove can be guided to the sound opening more quickly and smoothly.

[0012] In a possible implementation of the first aspect, the frame portion is provided with a sound-passing opening, and the sound-passing opening is connected to the sound-passing opening. In this way, the sound between the audio device and the outside world can be communicated not only through the sound-passing gap provided between the frame portion and the display screen, but also through the sound-passing opening, thereby increasing the total sound-passing area. In this way, the effect of balancing the airflow in the sound-passing channel can be achieved, thereby avoiding the problem of noise in the sound caused by the large airflow in the sound-passing channel due to the small cross-sectional area of ​​the sound-passing channel. In addition, by providing a sound-passing opening in the portion of the frame portion where the sound-passing opening is located, the grease and water stains guided to the sound-passing opening can be discharged to the outside of the shell through the sound-passing opening, avoiding their accumulation inside the shell and corroding other components in the electronic device, thereby further improving the reliability of the electronic device and extending the service life of the electronic device.

[0013] In a possible implementation of the first aspect, the housing further comprises a middle plate portion, the frame portion is arranged around the edge of the middle plate portion, the boss is located at the front side of the middle plate portion, the middle plate portion is provided with a sound-through groove with an open front side, the sound-through groove is connected to the sound-through opening, and the bottom wall of the sound-through groove is provided with an opening for connecting the audio device. In this way, a connecting channel for connecting the audio device and the sound-through gap between the display module and the middle plate portion is formed between the display module and the sound-through groove, so that the cross-sectional area of ​​the connecting channel can be increased without increasing the overall gap between the display module and the middle plate portion, thereby facilitating the thinning of the electronic device.

[0014] In a possible implementation of the first aspect, a convex rib is provided in the sound-through groove to separate the sound-through groove into a first sound-through groove portion and a second sound-through groove portion, the second sound-through groove portion is located on a side of the first sound-through groove portion away from the sound-through opening, and the opening is provided on the bottom wall of the second sound-through groove portion. In this way, grease and water stains at the sound-through opening can be gathered in the first sound-through groove portion, which can prevent grease and water stains from spreading wantonly inside the electronic device and corroding other components inside the electronic device. In addition, the first sound-through groove portion and the second sound-through groove portion are separated by the convex rib, and the first sound-through groove portion and the second sound-through groove portion are not connected to each other, so that the grease and water stains gathered in the first sound-through groove portion will not enter the second sound-through groove portion, thereby preventing grease and water stains from corroding the audio device through the opening.

[0015] In a possible implementation of the first aspect, the front edge of the convex rib is located behind the front edge of the sound-passing groove. In this way, the gap between the front edge of the convex rib and the display module is larger than the gap between the front edge of the sound-passing groove and the display module, thereby preventing the convex rib from affecting the cross-sectional area of ​​the communication channel between the audio device and the sound-passing gap, thereby ensuring normal sound communication between the audio device and the outside world.

[0016] In a possible implementation of the first aspect, a plurality of protrusions arranged in an array are provided on the bottom wall of the first sound passage groove portion, so that a water drop angle between grease and water stains and the bottom wall of the first sound passage groove portion can be increased, and grease and water stains can be better gathered in the first sound passage groove portion, thereby facilitating the grease and water stains to be discharged to the outside of the electronic device through the sound passage port.

[0017] In a possible implementation of the first aspect, a portion of the frame portion where the sound-passing opening is located is provided with a sound-passing port, which is communicated with the first sound-passing groove portion, so that grease and water stains collected in the first sound-passing groove portion can be discharged to the outside of the electronic device through the sound-passing port.

[0018] In a possible implementation of the first aspect, the portion of the frame portion where the sound-passing opening is located constitutes a portion of the sidewall of the first sound-passing groove portion, and the sound-passing opening is located on the sidewall of the first sound-passing groove. In this way, the first sound-passing groove portion can be closely attached to the frame portion where the sound-passing opening is located, and grease and water stains in the region of the frame portion where the sound-passing opening is located can directly flow into the first sound-passing groove portion, thereby better preventing grease and water stains from corroding other components in the electronic device.

[0019] In a possible implementation of the first aspect, one end of the guide groove that passes through the boss and faces the side wall of the sound-passing opening is the first end, and the projection of the edge of the first end in the front wall of the middle plate overlaps with the projection of the edge of the first sound-passing groove in the front wall of the middle plate; or the projection of the edge of the first end in the front wall of the middle plate is located within the projection area of ​​the first sound-passing groove in the front wall of the middle plate. In this way, when the grease and water stains in the guide groove are guided from the first end toward the sound-passing opening, the grease and water stains can be directly guided into the first sound-passing groove along the side wall of the boss, and will not flow to other areas on the middle plate, thereby better preventing the grease and water stains from corroding other components in the electronic device.

[0020] In a possible implementation of the first aspect, the width of the side wall surface of the boss facing the sound passage opening gradually decreases from the front to the back, so that the side wall surface of the boss facing the sound passage opening can have a diversion function, so that grease and water stains on the diversion groove and the bearing surface can be more quickly and smoothly guided into the first sound passage groove portion.

[0021] In a possible implementation of the first aspect, a first arc transition surface is provided between the side wall surface of the boss facing the sound-passing opening and the bearing surface; and / or a second arc transition surface is provided between the side wall surface of the boss facing the sound-passing opening and the bottom wall of the guide groove. By providing the first arc transition surface, a smooth transition can be made between the bearing surface and the side wall surface of the boss facing the sound-passing opening, so that grease and water stains on the bearing surface can be more smoothly guided to the side wall surface of the boss facing the sound-passing opening through the first arc transition surface. Similarly, by providing the second arc transition surface, a smooth transition can be made between the bottom wall of the guide groove and the side wall surface of the boss facing the sound-passing opening, so that grease and water stains in the guide groove can be more smoothly guided to the side wall surface of the boss facing the sound-passing opening through the second arc transition surface.

[0022] In a possible implementation of the first aspect, one end of the bearing surface facing the sound-passing opening has a first guide section surface, and the width of the first guide section surface gradually decreases in the direction toward the sound-passing opening; and / or one end of the guide groove facing the sound-passing opening has a second guide section surface, and the width of the second guide section surface gradually decreases in the direction toward the sound-passing opening. In this way, the first guide section surface has the function of guiding grease and water stains toward the sound-passing opening, and the grease and water stains on the bearing surface can be smoothly and quickly guided to the sound-passing opening through the first guide section surface, so as to avoid the grease and water stains from accumulating on the bearing surface and entering the interior of the display screen to corrode the display screen. The second guide section surface has the function of guiding grease and water stains toward the sound-passing opening, and the grease and water stains in the guide groove can be smoothly and quickly guided to the sound-passing opening through the second guide section surface, so as to avoid the grease and water stains from accumulating in the guide groove.

[0023] In a possible implementation of the first aspect, the edge of the first guide section surface facing the sound opening is an arc convex toward the sound opening; and / or the edge of the second guide section surface facing the sound opening is an arc convex toward the sound opening. In this way, the edges of the first guide section surface and the second guide section surface facing the sound opening are relatively smooth, and the structure is beautiful and easy to process.

[0024] In a possible implementation of the first aspect, the inner wall surface of the boss extends obliquely from the front to the rear in a direction close to the frame portion. In this way, while reducing the space occupied by the boss inside the shell, the front wall surface of the boss can be ensured to have a larger area, thereby ensuring the area of ​​the bearing surface on the front wall surface of the boss, and further ensuring the reliability of the connection between the light-transmitting cover plate and the bearing surface. In addition, by reducing the space occupied by the boss inside the shell, the utilization rate of the internal space of the shell can be improved.

[0025] In a possible implementation of the first aspect, the boss includes a body section and an avoidance section, the avoidance section is connected to the body section and extends to the sound-passing opening, and the inner wall surface of the avoidance section is closer to the frame portion than the inner wall surface of the body section. By making the inner wall surface of the avoidance section closer to the frame portion, the avoidance section has an avoidance effect on the side sealant, the avoidance section frees up accommodating space for the side sealant, and the circumferential end of the side sealant extends to the inner side of the inner wall surface of the avoidance section, but does not extend to the inner side of the inner wall surface of the body section.

[0026] In a possible implementation of the first aspect, the length of the guide groove extending along the circumference of the frame portion is greater than or equal to the length of the avoidance section extending along the circumference of the frame portion. In this way, it can be ensured that grease and water stains on the wall surface of the boss where the bearing surface of the avoidance section is located can be timely guided to the sound opening through the guide groove.

[0027] In a second aspect, an electronic device is provided, the electronic device comprising: a display screen and a housing as described in any of the above technical solutions. The display screen comprises a light-transmitting cover plate and a display module; the light-transmitting cover plate is bonded to the bearing surface, a sound-transmitting gap is provided between the frame portion and the display screen, and a sound-transmitting channel connected to the sound-transmitting gap is formed between the display screen, the sound-transmitting opening and the frame portion.

[0028] Since the electronic device provided in the present application includes a housing as described in any of the above technical solutions, both can solve the same problem and achieve the same effect. BRIEF DESCRIPTION OF THE DRAWINGS

The transparent cover plate 21 and the display module 22 are stacked, and the transparent cover plate 21 is located on the display side of the display module 22 (for example, Figure 3 and Figure 4 The light-transmitting cover plate 21 shown in the figure is located on the side of the display module 22 in the positive direction of the Z axis), that is, when the user uses the electronic device 100, the light-transmitting cover plate 21 faces the user. The light-transmitting cover plate 21 and the display module 22 can be relatively fixed by adhesive connection. Exemplarily, the light-transmitting cover plate 21 and the display module 22 can be bonded and fixed by OCA glue (optically clear glue).

[0069] The area of ​​the light-transmitting cover plate 21 is larger than the area of ​​the display module 22, and the circumferential side of the light-transmitting cover plate 21 protrudes from the circumferential side of the display module 22. The light-transmitting cover plate 21 completely covers the display module 22, and the light-transmitting cover plate 21 is mainly used to protect the display module 22 and prevent dust. The material of the light-transmitting cover plate 21 includes but is not limited to glass. The light-transmitting cover plate 21 also has the functions of anti-impact, scratch-resistant, oil-resistant, anti-fingerprint, and enhanced light transmittance.

[0070] The display module 22 may be a flexible display module or a rigid display module. For example, the display module 22 may be an organic light-emitting diode (OLED) display module, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display module, a mini organic light-emitting diode (MILLED) display module, a micro organic light-emitting diode (MILLED) display module, a micro organic light-emitting diode (MILLED) display module, a quantum dot light-emitting diode (QLED) display module, a liquid crystal display (LCD) module, etc.

[0071] The display screen 2 is connected to the housing 1. Specifically, the transparent cover plate 21 of the display screen 2 is connected to the housing 1. The back cover 11 is located on the side of the display screen 2 away from the transparent cover plate 21. When the electronic device 100 does not include the front housing 13 in the above embodiment, please refer to Figure 3 , the edge of the light-transmitting cover plate 21 can be bonded to the frame 121, so as to realize the connection between the light-transmitting cover plate 21 and the housing 1. At this time, the frame 121 is located between the light-transmitting cover plate 21 and the back cover 11. The light-transmitting cover plate 21, the frame 121 and the back cover 11 together form the external structure of the electronic device 100. The display module 22, the circuit board 3, the battery 4 and other devices are all located inside the electronic device 100. When the electronic device 100 includes the front housing 13 in the above-mentioned embodiment, please refer to Figure 4 The edge portion of the light-transmitting cover plate 21 can be bonded to the front frame 131, thereby realizing the connection between the light-transmitting cover plate 21 and the shell 1. At this time, the front frame 131 and the frame 121 are both located between the light-transmitting cover plate 21 and the back cover 11. The light-transmitting cover plate 21, the front frame 131, the frame 121 and the back cover 11 together form the external structure of the electronic device 100, and the display module 22, the circuit board 3, the battery 4 and other devices are all located inside the electronic device 100.

[0072] As can be seen from the above, the transparent cover plate 21 can be connected to the frame 121 or the front frame 131. For the convenience of the following description, the "frame 121" or "front frame 131" connected to the transparent cover plate 21 is defined as the "frame portion 101". That is, when the housing 1 does not include the front housing 13, and the edge of the transparent cover plate 21 is bonded to the frame 121, please refer to Figure 3 ,, in this case, the frame portion 101 refers to the frame 121; when the housing 1 includes the front housing 13, and the edge of the light-transmitting cover plate 21 is bonded to the front frame 131, please refer to Figure 4 At this time, the frame portion 101 refers to the front frame 131.

[0073] At the same time, the "middle plate 122" or "front middle plate 132" is also defined as the "middle plate portion 102". When the frame 121 is used as the frame portion 101, the middle plate 122 is used as the middle plate portion 102; when the front frame 131 is used as the frame portion 101, the front middle plate 132 is used as the middle plate portion 102.

[0074] See also Figure 4 , a boss 1011 is provided on the inner peripheral wall of the frame portion 101, the boss 1011 extends along the circumference of the frame portion 101, and the boss 1011 has a bearing surface 10111, and the bearing surface 10111 is used to bond the transparent cover plate 21 of the display screen 2. By providing the boss 1011 on the inner peripheral wall of the frame portion 101, a bearing surface 10111 for supporting and bonding the transparent cover plate 21 can be formed on the boss 1011, and a colloid 1004 is provided between the transparent cover plate 21 and the bearing surface 10111 to bond the transparent cover plate 21 to the bearing surface 10111. By bonding the transparent cover plate 21 to the bearing surface 10111, the transparent cover plate 21 is bonded to the frame portion 101.

[0075] As people have higher and higher requirements on the screen appearance of the electronic device 100, the higher the screen-to-body ratio, the better the visual effect, so narrow frame and full screen design have become the development trend. In order to improve the screen-to-body ratio of the electronic device 100, the width of the boss 1011 is made narrower and narrower, so that the width of the bearing surface 10111 on the boss 1011 for bonding the transparent cover plate 21 is narrower and narrower. In this way, when dispensing glue on the bearing surface 10111, the colloid 1004 is easy to fall off the bearing surface 10111, which makes it difficult to evenly press the colloid 1004 between the bearing surface 10111 and the transparent cover plate 21, and there will be a sealing gap between the bearing surface 10111 and the transparent cover plate 21, resulting in sealing failure.

[0076] Understandably, see Figure 4 There will inevitably be a gap 1003 between the transparent cover plate 21 of the display screen 2 and the frame portion 101 of the shell 1. External grease and water stains (such as user's sweat, etc.) are easily accumulated in the gap 1003. At this time, grease and water stains are easy to enter the interior of the display screen 2 through the sealing gap between the bearing surface 10111 and the transparent cover plate 21 to corrode the display screen 2. For example, the OCA glue (optically transparent glue) between the transparent cover plate 21 and the display module 22 will swell, thereby causing yellow spots to appear on the display screen 2, affecting the display effect of the display screen 2. Figure 4 The middle arrow indicates the movement path of external grease and water stains entering the gap 1003 between the display screen 2 and the frame portion 101 and entering the interior of the display screen 2 through the sealed gap between the transparent cover plate and the bearing surface.

[0077] At the same time, in order to achieve an ultra-high screen-to-body ratio, the electronic device 100 generally adopts a narrow gap sound transmission solution, that is, in order to achieve the effect of sound transmission, a sound transmission gap 1001 is formed between the display screen 2 and the frame portion 101. It can be the top of the display screen 2 (such as Figure 1 A sound-through gap 1001 is formed between the end of the display screen 2 along the positive direction of the Y axis) and the frame portion 101, which can be the bottom end of the display screen 2 (such as Figure 1 A sound-through gap 1001 is formed between the left end of the display screen 2 (eg, the negative end of the display screen 2 along the Y axis) and the frame portion 101. Figure 1 A sound-through gap 1001 is formed between the end of the display screen 2 along the negative direction of the X-axis) and the frame portion 101, and the right end of the display screen 2 (such as Figure 1 A sound-transmitting gap 1001 is formed between one end of the middle display screen 2 along the positive direction of the X-axis and the frame portion 101 .

[0078] Please return to Figure 1 The electronic device 100 is provided with an audio device 5, and the sound-passing gap 1001 is used to communicate with the audio device 5. The audio device 5 may be a device that converts an audio electrical signal into a sound signal, and exemplarily, the audio device 5 may be a speaker or a receiver, etc.; the audio device 5 may also be a device that converts a sound signal into an electrical signal, and exemplarily, the audio device 5 may be a microphone, etc.; the audio device 5 may also be a device that has the functions of converting an audio electrical signal into a sound signal and converting a sound signal into an audio electrical signal at the same time.

[0079] The sound gap 1001 is connected to the audio device 5, so that the sound signal emitted by the audio device 5 can be transmitted from the inside of the electronic device 100 to the outside of the electronic device 100 to be received by the user. At this time, the sound gap 1001 is a sound output gap for sound output; or the external sound signal can be transmitted to the inside of the electronic device 100 through the sound gap 1001 to be collected and received by the audio device 5. At this time, the sound gap 1001 is a sound pickup port for collecting sound.

[0080] For example, see Figure 1 , the audio device 5 is a receiver, the sound-passing gap 1001 is a sound-emitting gap, and is disposed at the top of the display screen 2. Based on this, the electronic device 100 of the embodiment of the present application can be an electronic device 100 in which the receiver uses a narrow gap to emit sound.

[0081] It is understandable that in order to ensure normal sound transmission at the sound transmission gap 1001 of the electronic device 100, the frame portion 101 and the transparent cover 21 at the sound transmission gap 1001 can no longer be bonded through the boss 1011, which will block the communication channel between the audio device 5 and the sound transmission gap 1001 and prevent sound transmission.

[0082] Based on this, see Figure 5 and Figure 6 ,in Figure 5 This is a partial structural diagram of the housing 1 of the electronic device 100 provided according to some embodiments of the present application. The boss 1011 has a sound-passing opening 10113, that is, the boss 1011 is disconnected at the portion opposite to the sound-passing gap 1001 to form the sound-passing opening 10113. Figure 6 , Figure 6 The electronic device 100 provided in some embodiments of the present application is Figure 1 In the cross-sectional view at the middle BB line, when the transparent cover plate 21 of the display screen 2 is bonded to the bearing surface 10111 of the boss 1011, a sound channel 1002 connected to the sound gap 1001 is formed between the display screen 2, the sound opening 10113 and the frame portion 101. In this way, the audio device 5 disposed inside the electronic device 100 can be connected to the sound gap 1001 through the sound channel 1002. When the audio device 5 is a receiver, the sound signal emitted by the audio device 5 can be transmitted along the Figure 6 When the audio device 5 is a microphone, the external sound signal can be transmitted to the outside in the direction of the straight arrow in the figure to be received by the user. Figure 6 The signal is transmitted in the direction of the curved arrow in FIG. 1 to the inside of the electronic device 100 to be received by the audio device 5 .

[0083] As can be seen from the above, by providing a sound-passing opening 10113 on the boss 1011, the audio device 5 provided in the electronic device 100 can be connected to the sound-passing gap 1001 through the sound-passing opening 10113, thereby ensuring normal sound transmission at the sound-passing gap 1001 while the display screen 2 is bonded to the frame portion 101.

[0084] Exemplarily, the sound gap 1001 may be directly opposite to the sound opening 10113, that is, the central axis of the sound gap 1001 parallel to the bearing surface 10111 may overlap with the central axis of the sound opening 10113 parallel to the bearing surface 10111. In this way, the structure of the electronic device 100 is symmetrical, which is convenient for production and processing, and the sound transmission effect is good. Of course, the present application is not limited to this. In some other examples, the sound gap 1001 and the sound opening 10113 may not be directly opposite.

[0085] In addition, in some examples, the extension length of the sound gap 1001 along the circumference of the frame portion 101 may be greater than the extension length of the sound opening 10113 along the circumference of the frame portion 101; in some examples, the extension length of the sound gap 1001 along the circumference of the frame portion 101 may be less than the extension length of the sound opening 10113 along the circumference of the frame portion 101; in some examples, the extension length of the sound gap 1001 along the circumference of the frame portion 101 may be equal to the extension length of the sound opening 10113 along the circumference of the frame portion 101.

[0086] In order to solve the above technical problems, in some embodiments of the present application, please refer to Figure 7 and Figure 8 ,in, Figure 7 The electronic device 100 provided in some embodiments of the present application is Figure 1 The local cross-section at the AA line. Figure 8 A schematic diagram of the partial structure of the shell 1 of the electronic device 100 provided in some embodiments of the present application, wherein a guide groove 10112 with an open front side is provided on the boss 1011, and the guide groove 10112 and the bearing surface 10111 are located on the same wall surface of the boss 1011, that is, a guide groove 10112 is provided on the wall surface of the boss 1011 where the bearing surface 10111 is located, and one end of the guide groove 10112 passes through the side wall surface of the boss 1011 facing the sound-passing opening 10113.

[0087] For details, please continue to see Figure 7 and Figure 8 , the bearing surface 10111 is located on the front wall surface of the boss 1011, that is, at least a part of the front wall surface of the boss 1011 constitutes the bearing surface 1011, and the guide groove 10112 is also provided on the front wall surface of the boss 1011, and the guide groove 10112 is on the front wall surface of the boss 1011 and extends along the circumference of the frame portion 101, one end of the guide groove 10112 in the circumferential direction extends toward the sound opening 10113 and passes through the side wall surface of the boss 1011 facing the sound opening 10113, and the other end of the guide groove 10112 in the circumferential direction extends in a direction away from the sound opening 10113. For the convenience of description, here, the end of the guide groove 10112 passing through the side wall surface of the boss 1011 facing the sound opening 10113 is referred to as the first end 10112a, and the end of the guide groove 10112 away from the first end 10112a is referred to as the second end 10112b.

[0088] It can be understood that after the transparent cover plate 21 of the display screen 2 is bonded to the bearing surface 10111, the gap 1003 between the transparent cover plate 21 and the frame portion 101 is directly opposite to the wall surface of the boss 1011 where the bearing surface 10111 is located in the front-to-back direction, and the grease and water stains from the outside will accumulate on the wall surface of the boss 1011 where the bearing surface 10111 is located. By providing a guide groove 10112 on the wall surface of the boss 1011 where the bearing surface 10111 is located, a part of the grease and water stains from the outside can directly enter and be collected in the guide groove 10112, and the other part of the grease and water stains can first fall to other areas on the front wall surface of the boss 1011, and then flow from other areas to the guide groove 10112. It should be noted that the "other areas" mentioned here refer to the areas on the front wall surface of the boss 1011 except the areas where the guide groove 10112 is located. Exemplarily, the other areas may include the areas where the bearing surface 10111 is located.

[0089] In this way, after the grease and water stains from the outside fall onto the wall surface where the bearing surface 10111 of the boss 1011 is located through the gap 1003 between the transparent cover plate 21 and the frame portion 101, they can be gathered in the guide groove 10112. Since the first end 10112a of the guide groove 10112 passes through the side wall surface of the boss 1011 facing the sound-passing opening 10113, that is, the guide groove 10112 is connected with the sound-passing opening 10113 through its first end 10112a, the grease and water stains gathered in the guide groove 10112 can be timely guided to the sound-passing opening 10113 through the first end 10112a of the guide groove 10112, thereby preventing the grease and water stains from accumulating on the wall surface of the boss 1011 where the bearing surface 10111 is located, and further preventing the grease and water stains from passing through the sealing gap between the bearing surface 10111 and the transparent cover plate 21 and entering the interior of the display screen 2 to erode the display screen 2.

[0090] In some embodiments of the present application, the guide groove 10112 is located on the side of the bearing surface 10111 facing the frame portion 101. In this way, the guide groove 10112 can be directly opposite to the gap 1003 between the frame portion 101 and the light-transmitting cover plate 21, or be close to the gap 1003, which makes it easier for water stains and grease to enter the guide groove 10112, so that the water stains and grease can be more timely guided out of the wall surface of the boss 1011 where the bearing surface 10111 is located. For example, please continue to refer to Figure 7 and Figure 8The guide groove 10112 is located on the side of the bearing surface 10111 facing the frame portion 101, and the guide groove 10112 is arranged next to the frame portion 101, that is, at least part of the structure of the frame portion 101 constitutes the groove side wall of the guide groove 10112, so that the guide groove 10112 can face the gap 1003 between the frame portion 101 and the transparent cover plate 21, and water stains and grease can more easily enter the guide groove 10112. In some other examples, the guide groove 10112 and the frame portion 101 can also be spaced apart from each other.

[0091] For further information, see Fig. 9 , Fig. 9 for Figure 8 The guide groove 10112 shown in the figure is a projection of the inner wall surface of the frame portion 101 in the plane where the inner wall surface of the frame portion 101 is located. The end of the side wall surface of the guide groove 10112 that passes through the boss 1011 and faces the sound-passing opening 10113 is the first end 10112a, and the end of the guide groove 10112 away from the first end 10112a is the second end 10112b. From the second end 10112b of the guide groove 10112 in the direction toward the first end 10112a of the guide groove 10112, the bottom wall 10112c of the guide groove 10112 extends obliquely in the direction away from the front side.

[0092] It is understandable that when the electronic device 100 is not in use, according to the user's habit, when placing the electronic device 100, the side where the display screen 2 of the electronic device 100 is located is generally facing away from the carrying platform (such as a desktop, etc.) of the electronic device 100, that is, the front side of the electronic device 100 is facing away from the carrying platform, and the back side of the electronic device 100 is facing the carrying platform. The direction from front to back of the electronic device 100 is consistent with the gravity direction of grease and water stains. By making the second end 10112b of the guide groove 10112 face the direction of the first end 10112a of the guide groove 10112, the bottom wall 10112c of the guide groove 10112 extends in a direction away from the front side, so that in the direction from the second end 10112b to the first end 10112a, the bottom wall 10112c of the guide groove 10112 extends obliquely along the gravity direction of grease and water stains. As a result, the grease and water stains collected in the guide groove 10112 can flow from the second end 10112b to the first end 10112a more quickly and smoothly, and then be guided from the first end 10112a to the sound opening 10113.

[0093] For further information, please refer to Fig. 9, the height difference ΔH between the bottom wall 10112c of the second end 10112b and the bottom wall 10112c of the first end 10112a is greater than or equal to 0.3mm. Exemplarily, the height difference ΔH between the bottom wall 10112c of the second end 10112b and the bottom wall 10112c of the first end 10112a can be 0.30mm, 0.35mm, 0.40mm, 0.45mm, 0.50mm, 0.55mm, 0.60mm, 0.65mm, 0.70mm, 0.75mm, 0.80mm, 0.90mm, 0.95mm, 1.00mm, 1.20mm, 1.30mm, 1.40mm or 1.50mm, etc.

[0094] It can be understood that, under the premise that the extension length of the guide groove 10112 along the circumferential direction of the frame portion 101 is constant, the greater the height difference ΔH between the bottom wall 10112c of the second end 10112b of the guide groove 10112 and the bottom wall 10112c of the first end 10112a, the greater the inclination angle of the bottom wall 10112c of the guide groove 10112, and the better the guiding effect of grease and water stains. By making the height difference ΔH between the bottom wall 10112c of the second end 10112b and the bottom wall 10112c of the first end 10112a greater than or equal to 0.3mm, the bottom wall 10112c of the guide groove 10112 has a larger inclination angle, so that the guide groove 10112 has a better guiding effect on grease and water stains, and the grease and water stains in the guide groove 10112 can be guided to the sound-passing opening 10113 more quickly and smoothly.

[0095] Optionally, the height difference ΔH between the bottom wall 10112c of the second end 10112b and the bottom wall 10112c of the first end 10112a is less than or equal to 1.5 mm. In other words, while ensuring that the bottom wall 10112c of the guide groove 10112 has a certain inclination angle to enhance the guiding effect, the inclination angle cannot be too large, which will affect the connection strength between the boss 1011 and the frame portion 101. In addition, too large an inclination angle will increase the difficulty of molding the housing 1.

[0096] In some embodiments of this application, please refer to Figure 8 The frame portion 101 is provided with a sound-through hole 1012, and the sound-through hole 1012 is connected to the sound-through opening 10113. Specifically, the portion of the frame portion 101 where the sound-through opening 10113 is located is provided with a sound-through hole 1012, and the sound-through hole 1012 is also used for sound communication between the audio device 5 and the outside world. The sound-through hole 1012 can be used for sound emission or sound pickup. By providing the sound-through hole 1012 in the frame portion 101, the sound communication between the audio device 5 and the outside world can be performed not only through the sound-through gap 1001 provided between the frame portion 101 and the display screen 2, but also through the sound-through hole 1012.

[0097] The sound opening 1012 and the sound gap 1001 are both connected to the sound channel 1002. The total sound area is increased by providing the sound opening 1012. In this way, the airflow in the sound channel 1002 can be balanced, thereby avoiding the problem of noise caused by a large airflow in the sound channel 1002 due to a small cross-sectional area of ​​the sound channel 1002.

[0098] In addition, by providing a sound vent 1012 in the portion of the frame portion 101 where the sound vent 10113 is located, the grease and water stains guided to the sound vent 10113 can be discharged to the outside of the shell 1 through the sound vent 1012, avoiding their accumulation inside the shell 1 and corroding other components in the electronic device 100, thereby further improving the reliability of the electronic device 100 and extending the service life of the electronic device 100.

[0099] In addition, it can be understood that the electronic device 100 adopts a narrow slit sound transmission scheme, and there is a sound transmission gap 1001 for sound transmission between the display screen 2 and the frame portion 101. During the use of the electronic device 100, grease and water stains from the outside can also directly enter the inside of the electronic device 100 through the sound transmission gap 1001. In this way, the sound transmission opening 10113 will not only collect the grease and water stains guided by the guide groove 10112, but also collect the grease and water stains that directly enter the inside of the electronic device 100 from the sound transmission gap 1001. By providing the sound transmission opening 1012 at the part of the frame portion 101 where the sound transmission opening 10113 is located, not only can the grease and water stains guided by the guide groove 10112 to the sound transmission opening 10113 be discharged to the outside of the housing 1, but also the grease and water stains that enter the electronic device 100 from the sound transmission gap 1001 can be guided to the outside of the housing 1.

[0100] The sound hole 1012 may be a single hole structure or a multi-hole structure. Figure 8 There are multiple sound holes 1012, and the multiple sound holes 1012 are sequentially spaced apart along the circumference of the frame portion 101. The shape of the sound holes 1012 can be arbitrarily selected as needed. For example, the sound holes 1012 can be circular, elliptical or polygonal.

[0101] In some implementations of this application, please continue to refer to Figure 8 In conjunction with Figure 6The shell 1 of the electronic device 100 also includes a middle plate portion 102, a frame portion 101 is arranged around the edge of the middle plate portion 102, and a boss 1011 is located on the front side of the middle plate portion 102. When the display screen 2 is bonded to the bearing surface 10111 of the boss 1011, the display screen 2 is located on the front side of the middle plate portion 102, and the display module 22 is located in the accommodating space enclosed by the transparent cover plate 21, the frame portion 101 and the front side wall of the middle plate portion 102.

[0102] The middle plate portion 102 is provided with a sound-through groove 1021 with an open front side, the sound-through groove 1021 is connected to the sound-through opening 10113, and the bottom wall of the sound-through groove 1021 is provided with an opening 10213a for connecting to the audio device 5. The audio device 5 is provided on the back side of the middle plate portion 102, that is, the audio device 5 is provided on the side of the middle plate portion 102 away from the display screen 2, and the audio device 5 is opposite to the opening 10213a, so as to ensure that the audio device 5 is connected to the outside through the opening 10213a, the sound-through opening 10113 and the sound-through gap 1001.

[0103] It can be understood that a part of the communication channel between the audio device 5 and the sound-passing gap 1001 is located between the display module 22 and the middle plate portion 102. The gap between the display module 22 and the middle plate portion 102 directly affects the sound-passing area of ​​the communication channel. By providing a sound-passing groove 1021 with an open front side in the middle plate portion 102, and the bottom wall of the sound-passing groove 1021 is provided with an opening 10213a that is connected to the audio device 5, the communication channel between the display module 22 and the middle plate portion 102 is formed between the display module 22 and the sound-passing groove 1021, that is, the space enclosed between the display module 22 and the sound-passing groove 1021 constitutes a part of the communication channel. In this way, the cross-sectional area of ​​the communication channel can be increased without increasing the overall gap between the display module 22 and the middle plate portion 102, thereby facilitating the thinning of the electronic device 100.

[0104] For further information, please refer to Figure 6 and Figure 8 The sound-passing groove 1021 is provided with a convex rib 10211 to separate the sound-passing groove 1021 into a first sound-passing groove portion 10212 and a second sound-passing groove portion 10213. The second sound-passing groove portion 10213 is located on a side of the first sound-passing groove portion 10212 away from the sound-passing opening 10113. For example, see Figure 6 and Figure 8 The first sound-through groove portion 10212 and the second sound-through groove portion 10213 are arranged along the direction of the Y-axis, and the second sound-through groove portion 10213 is located on the negative side of the first sound-through groove portion 10212 along the Y-axis. Compared with the second sound-through groove portion 10213, the first sound-through groove portion 10212 is closer to the sound opening 10113, and the opening 10213a is provided on the bottom wall of the second sound-through groove portion 10213.

[0105] In this way, the grease and water stains guided by the guide groove 10112 to the sound passage opening 10113, as well as the grease and water stains that enter the electronic device 100 from the sound passage gap 1001 can be gathered in the first sound passage groove portion 10212. This can prevent the grease and water stains guided by the guide groove 10112 to the sound passage opening 10113, as well as the grease and water stains that enter the electronic device 100 from the sound passage gap 1001 from spreading wantonly inside the electronic device 100 and corroding other components inside the electronic device 100.

[0106] In addition, the first sound groove portion 10212 and the second sound groove portion 10213 are separated by the rib 10211, and the first sound groove portion 10212 and the second sound groove portion 10213 are not connected to each other, so that grease and water stains collected in the first sound groove portion 10212 will not enter the second sound groove portion 10213, thereby preventing grease and water stains from corroding the audio device 5 through the opening 10213a.

[0107] On the basis of the above, please continue to refer to Figure 6 and Figure 8 The sound-through opening 1012 provided in the frame portion 101 is connected to the first sound-through groove portion 10212. In this way, the grease and water stains collected in the first sound-through groove portion 10212 can be discharged to the outside of the electronic device 100 through the sound-through opening 1012.

[0108] For further information, please refer to Figure 6 and Figure 8 The portion of the frame portion 101 where the sound opening 10113 is located constitutes a portion of the groove side wall of the first sound groove portion 10212, and the sound opening 1012 is located on the groove side wall of the first sound groove portion 10212. That is, the portion of the frame portion 101 where the sound opening 1012 is located constitutes a portion of the groove side wall of the first sound groove portion 10212, and the sound opening 1012 is located exactly on the portion of the groove side wall, so that the sound opening 1012 can be directly connected to the first sound groove portion 10212, thereby simplifying the overall structure of the housing 1.

[0109] In addition, by making the portion of the frame portion 101 where the sound opening 10113 is located constitute a partial groove side wall of the first sound groove portion 10212, the first sound groove portion 10212 can be tightly attached to the frame portion 101 where the sound opening 10113 is located, and grease and water stains in the area of ​​the frame portion 101 where the sound opening 10113 is located can directly flow into the first sound groove portion 10212, thereby better preventing grease and water stains from corroding other components in the electronic device 100.

[0110] Of course, the present application is not limited to this. In some other embodiments, the frame portion 101 where the sound opening 10113 is located does not constitute the side wall of the first sound passing groove portion 10212 , and the sound opening 1012 is indirectly connected to the first sound passing groove portion 10212 .

[0111] Please continue reading Figure 6 and Figure 8 The front end edge of the rib 10211 is located on the rear side of the front end edge of the sound-passing groove 1021. In this way, the gap between the front end edge of the rib 10211 and the display module 22 is larger than the gap between the front end edge of the sound-passing groove 1021 and the display module 22. This can avoid the cross-sectional area of ​​the connecting channel between the audio device 5 and the sound-passing gap 1001 being affected by the setting of the rib 10211, thereby ensuring normal sound communication between the audio device 5 and the outside world.

[0112] See also Figure 8 A plurality of protrusions 10212a arranged in an array are provided on the bottom wall of the first sound-passing groove 10212. By providing a plurality of protrusions 10212a arranged in an array, the water drop angle between grease and water stains and the bottom wall of the first sound-passing groove 10212 can be increased, and grease and water stains can be better gathered in the first sound-passing groove 10212, so that the grease and water stains can be discharged to the outside of the electronic device 100 through the sound-passing port 1012.

[0113] Among them, the protrusion 10212a can be formed on the bottom wall of the first sound groove portion 10212 by laser engraving technology. This not only has a simple processing technology and low cost, but also the surface roughness of the protrusion 10212a processed by the laser engraving technology is relatively high, thereby making the water drop angle between grease and water stains and the bottom wall of the first sound groove portion 10212 larger, and the first sound groove portion 10212 has a better effect in collecting grease and water stains.

[0114] Of course, the present application is not limited to this. The protrusion 10212a can also be formed integrally on the bottom wall of the first sound groove portion 10212 through an injection molding process; or the protrusion 10212a can also be formed separately, and then the protrusion 10212a can be fixed to the bottom wall of the first sound groove portion 10212 through a process such as bonding or welding.

[0115] It is understandable that the arrangement of the plurality of protrusions 10212a on the bottom wall of the first sound-passing groove portion 10212 is not limited to the above-mentioned array arrangement, and the arrangement can be arbitrarily selected as needed. In some other examples, the plurality of protrusions 10212a on the bottom wall of the first sound-passing groove portion 10212 can also be arranged in a circular array.

[0116] Please continue reading Figure 8, the projection of the edge of the first end 10112a of the guide groove 10112 on the front wall of the middle plate 102 overlaps with the projection of the edge of the first sound-passing groove 10212 on the front wall of the middle plate 102. In this way, when the grease and water stains in the guide groove 10112 are guided from the first end 10112a toward the sound-passing opening 10113, the grease and water stains can be directly guided into the first sound-passing groove 10212 along the side wall of the boss 1011, and will not flow to other areas on the middle plate 102, thereby better preventing the grease and water stains from corroding other components in the electronic device 100.

[0117] In some other embodiments, the projection of the edge of the first end 10112a of the guide groove 10112 in the front wall surface of the middle plate portion 102 is located within the projection area of ​​the first sound-passing groove portion 10212 in the front wall surface of the middle plate portion 102. Similarly, when the grease and water stains in the guide groove 10112 are guided from the first end 10112a toward the sound-passing opening 10113, the grease and water stains can be directly guided into the first sound-passing groove portion 10212 along the side wall surface of the boss 1011, and will not flow to other areas on the middle plate portion 102, thereby better preventing the grease and water stains from corroding other components in the electronic device 100.

[0118] See also Fig.10 , Fig.10 for Figure 8 In the partial enlarged view of the housing 1 in FIG. 1 , one end of the bearing surface 10111 facing the sound-passing opening 10113 has a first guide section surface 1015, and the width of the first guide section surface 1015 gradually decreases in the direction toward the sound-passing opening 10113. In this way, the first guide section surface 1015 has the function of guiding grease and water stains toward the sound-passing opening 10113, and the grease and water stains on the bearing surface 10111 can be smoothly and quickly guided to the sound-passing opening 10113 through the first guide section surface 1015, so as to prevent the grease and water stains from accumulating on the bearing surface 10111 and entering the interior of the display screen 2 to corrode the display screen 2.

[0119] For example, please refer to Fig.10 The edge of the first guide section surface 1015 facing the sound opening 10113 is an arc convex toward the sound opening 10113, and the first guide section surface 1015 can be formed into a semicircle. In this way, the edge of the first guide section surface 1015 facing the sound opening 10113 is relatively smooth, and the structure is beautiful and easy to process.

[0120] Of course, the present application is not limited thereto, and the edge of the first guide segment surface 1015 facing the sound passage opening 10113 may also be composed of multiple straight line segments. Fig.11 , Fig.11A partial enlarged view of the housing 1 of the electronic device 100 provided in some embodiments of the present application, wherein the edge of the first guide section surface 1015 facing the sound opening 10113 includes a first straight line segment 10151 and a second straight line segment 10152, and in the direction toward the sound opening 10113, the first straight line segment 10151 and the second straight line segment 10152 extend in a direction close to each other until the two intersect, and at this time the first guide section surface 1015 can be formed into a triangle.

[0121] Similarly, please refer back to Fig.10 The end of the guide groove 10112 facing the sound opening 10113 has a second guide section surface 1016, and the width of the second guide section surface 1016 gradually decreases in the direction toward the sound opening 10113. In this way, the second guide section surface 1016 has the function of guiding grease and water stains toward the sound opening 10113. The grease and water stains in the guide groove 10112 can be smoothly and quickly guided to the sound opening 10113 through the second guide section surface 1016, thereby preventing the grease and water stains from accumulating in the guide groove 10112.

[0122] For example, please refer to Fig.10 The edge of the second guide section surface 1016 facing the sound opening 10113 is an arc convex toward the sound opening 10113, and the second guide section surface 1016 can be formed into a semicircle. In this way, the edge of the second guide section surface 1016 facing the sound opening 10113 is relatively smooth, and the structure is beautiful and easy to process.

[0123] Of course, the present application is not limited thereto, and the edge of the second guide segment surface 1016 facing the sound passage opening 10113 may also be composed of multiple straight line segments. Fig.11 The edge of the second guide section surface 1016 facing the sound opening 10113 includes a third straight line segment 10161 and a fourth straight line segment 10162. In the direction toward the sound opening 10113, the third straight line segment 10161 and the fourth straight line segment 10162 extend toward each other until they intersect. At this time, the second guide section surface 1016 can be formed into a triangle.

[0124] In some other examples, only the bearing surface 10111 is provided with the first guide section surface 1015 , and the guide groove 10112 is not provided with the second guide section surface 1016 .

[0125] In some other examples, the first guide section surface 1015 is not provided on the bearing surface 10111 , and only the second guide section surface 1016 is provided on the guide groove 10112 .

[0126] In some embodiments of this application, please refer to Fig.12 and Fig.13 ,in, Fig.12 A schematic diagram of a partial structure of a housing 1 of an electronic device 100 provided in some embodiments of the present application. Fig.13 for Fig.12 In the schematic diagram of the partial structure of the shell 1 at another angle shown in the figure, the width of the side wall surface of the boss 1011 facing the sound-passing opening 10113 gradually decreases from the front to the back. It can be understood that the grease and water stains in the guide groove 10112 and the grease and water stains on the bearing surface 10111 will flow along the side wall surface of the boss 1011 facing the sound-passing opening 10113 to the first sound-passing groove portion 10212. By gradually reducing the width of the side wall surface of the boss 1011 facing the sound-passing opening 10113 from the front to the back, the side wall surface of the boss 1011 facing the sound-passing opening 10113 has a diversion function, so that the grease and water stains on the guide groove 10112 and the bearing surface 10111 can be guided into the first sound-passing groove portion 10212 more quickly and smoothly. For example, please refer to Fig.13 The side wall surface of the boss 1011 facing the sound opening 10113 can be formed into an inverted triangle structure.

[0127] Please continue reading Fig.13 A first arc transition surface 1013 is provided between the side wall surface of the boss 1011 facing the sound-passing opening 10113 and the bearing surface 10111, and a second arc transition surface 1014 is provided between the side wall surface of the boss 1011 facing the sound-passing opening 10113 and the bottom wall 10112c of the guide groove 10112. By providing the first arc transition surface 1013, a smooth transition can be achieved between the bearing surface 10111 and the side wall surface of the boss 1011 facing the sound-passing opening 10113, so that grease and water stains on the bearing surface 10111 can be more smoothly guided to the side wall surface of the boss 1011 facing the sound-passing opening 10113 through the first arc transition surface 1013. Similarly, by setting a second circular arc transition surface 1014, a smooth transition can be achieved between the bottom wall 10112c of the guide groove 10112 and the side wall surface of the boss 1011 facing the sound opening 10113, so that the grease and water stains in the guide groove 10112 can be more smoothly guided to the side wall surface of the boss 1011 facing the sound opening 10113 through the second circular arc transition surface 1014.

[0128] For example, see Fig.13 The first arc transition surface 1013 and the second arc transition surface 1014 are both formed as arc structures protruding toward the light-transmitting cover plate 21. Of course, the present application is not limited to this. In another example, please refer to Fig.14 , Fig.14This is a partial enlarged view of the housing 1 of the electronic device 100 provided in some embodiments of the present application. The first arc transition surface 1013 and the second arc transition surface 1014 can also be formed as an arc surface structure convex in the direction away from the transparent cover plate 21.

[0129] Or see Fig.15 , Fig.15 A partial enlarged view of the housing 1 of the electronic device 100 provided in some embodiments of the present application, wherein the first arc transition surface 1013 includes a first sub-transition surface 10131 and a second sub-transition surface 10132 connected to each other, wherein the first sub-transition surface 10131 is formed as a curved surface structure protruding toward the light-transmitting cover plate 21, and the second sub-transition surface 10132 is formed as a curved surface structure protruding toward a direction away from the light-transmitting cover plate 21, so that the overall length of the first arc transition surface 1013 can be increased, and the guiding effect on grease and water stains can be better. In some other examples, the first sub-transition surface 10131 can also be formed as a curved surface structure protruding toward a direction away from the light-transmitting cover plate 21, and the second sub-transition surface 10132 can be formed as a curved surface structure protruding toward the light-transmitting cover plate 21.

[0130] Likewise, please continue to read Fig.15 The second arc transition surface 1014 includes a third sub-transition surface 10141 and a fourth sub-transition surface 10142 connected to each other. The third sub-transition surface 10141 is formed as a curved surface structure protruding toward the light-transmitting cover plate 21, and the fourth sub-transition surface 10142 is formed as a curved surface structure protruding in a direction away from the light-transmitting cover plate 21. In this way, the overall length of the second arc transition surface 1014 can be increased, and the guiding effect on grease and water stains can be better. In some other examples, the third sub-transition surface 10141 can also be formed as a curved surface structure protruding in a direction away from the light-transmitting cover plate 21, and the fourth sub-transition surface 10142 can be formed as a curved surface structure protruding in a direction toward the light-transmitting cover plate 21.

[0131] In some other embodiments, the above-mentioned first arc transition surface 1013 is only provided between the side wall surface of the boss 1011 facing the sound opening 10113 and the bearing surface 10111, and the above-mentioned second arc transition surface 1014 is not provided between the side wall surface of the boss 1011 facing the sound opening 10113 and the bottom wall 10112c of the guide groove 10112.

[0132] In another embodiment, the second arc transition surface 1014 is provided only between the side wall surface of the boss 1011 facing the sound-passing opening 10113 and the bottom wall 10112c of the guide groove 10112, and the first arc transition surface 1013 is not provided between the side wall surface of the boss 1011 facing the sound-passing opening 10113 and the bearing surface 10111.

[0133] See also Figure 13-Figure 15, the inner wall surface of the boss 1011 extends obliquely from the front to the rear in the direction close to the frame portion 101. In other words, the cross-sectional area of ​​the boss 1011 in the plane parallel to the bearing surface 10111 gradually decreases from the front to the rear, so that the space occupied by the boss 1011 inside the housing 1 can be reduced while ensuring that the front wall surface of the boss 1011 has a larger area, thereby ensuring the area of ​​the bearing surface 10111 on the front wall surface of the boss 1011, and further ensuring the reliability of the connection between the transparent cover plate 21 and the bearing surface 10111. In addition, by reducing the space occupied by the boss 1011 inside the housing 1, the utilization rate of the internal space of the housing 1 can be improved.

[0134] In some examples, the boss 1011 and the frame portion 101 are integrally formed, that is, the boss 1011 and the frame portion 101 are processed as one piece, so that the connection strength between the boss 1011 and the frame portion 101 is high and the processing technology is simple. In some other examples, the boss 1011 and the frame portion 101 can also be separate structural parts, and the boss 1011 is connected to the frame portion 101 by bonding, welding or threaded connection after being formed separately.

[0135] It can be understood that since the electronic device 100 adopts a narrow gap sound transmission method, during the use of the electronic device 100, the user's sweat and water stains such as moisture in the external environment and grease can easily enter the interior of the electronic device 100 through the sound transmission gap 1001, and the water stains and grease can be transmitted to the display module 22. The display module 22 includes multiple sub-functional layers, and the multiple sub-functional layers are stacked. Therefore, the circumferential side of the display module 22 is composed of the circumferential side of multiple sub-functional layers. The water stains and grease transmitted to the circumferential side of the display module 22 can easily enter the interior of the display module 22 through the gap between adjacent sub-functional layers, thereby affecting the normal operation of the display module 22.

[0136] Based on this, in order to prevent the circumferential side of the display module 22 from being corroded by water stains and grease, please refer to Fig.16 and Fig.17 ,in Fig.16 This is a schematic diagram of a partial structure of an electronic device 100 at a sound-passing gap 1001 in some embodiments of the present application, wherein the display screen 2 and the sound-passing groove 1021 are not shown in the figure; Fig.17 The electronic device 100 of some embodiments of the present application is Fig.16 As shown in the partial cross-sectional view at the CC line in the figure, a side sealant 6 is provided on at least the circumferential side of the display module 22 facing the sound-passing gap 1001. By providing the side sealant 6, the gap between adjacent sub-functional layers can be sealed, thereby preventing water stains and grease from entering the interior of the display module 22.

[0137] Optionally, the side sealing glue 6 is directly opposite to the sound-passing gap 1001, and the circumferential extension length of the side sealing glue 6 is greater than the circumferential extension length of the sound-passing gap 1001, and the circumferential ends of the side sealing glue 6 extend to the inner side of the inner wall surface of the boss 1011 located on both sides of the sound-passing opening 10113, respectively. In this way, the side sealing glue 6 has better sealing performance on the circumferential side of the display module 22 opposite to the sound-passing gap 1001.

[0138] To avoid side sealant 6, please refer to Fig.16 Combined with Fig.12 The boss 1011 includes a main body section 1017 and an avoidance section 1018. The avoidance section 1018 is connected to the main body section 1017 and extends to the sound-passing opening 10113. Compared with the inner wall surface of the main body section 1017, the inner wall surface of the avoidance section 1018 is closer to the frame portion 101. By making the inner wall surface of the avoidance section 1018 closer to the frame portion 101, the avoidance section 1018 has an avoidance effect on the side sealant 6. The avoidance section 1018 vacates an accommodating space for the side sealant 6. The circumferential end of the side sealant 6 extends to the inner side of the inner wall surface of the avoidance section 1018, but does not extend to the inner side of the inner wall surface of the main body section 1017.

[0139] It is understandable that the width of the bearing surface 10111 on the avoidance section 1018 is obviously smaller than the width of the bearing surface 10111 on the main body section 1017. In this way, it is more difficult to dispense glue on the bearing surface 10111 of the avoidance section 1018, and the colloid 1004 is more likely to fall off the bearing surface 10111 of the avoidance section 1018. It is more difficult to evenly press the colloid 1004 between the bearing surface 10111 of the avoidance section 1018 and the light-transmitting cover plate 21, and it is more likely that there is a sealed gap between the bearing surface 10111 of the avoidance section 1018 and the light-transmitting cover plate 21. In other words, there is a greater risk that the grease and water stains accumulated in the gap 1003 between the light-transmitting cover plate 21 and the frame portion 101 enter the interior of the display screen 2 through the sealed gap between the bearing surface 10111 of the avoidance section 1018 and the light-transmitting cover plate 21.

[0140] Therefore, please continue to read Fig.16 At least the avoidance section 1018 of the boss 1011 is provided with a guide groove 10112, and further, the length of the guide groove 10112 extending along the circumference of the frame portion 101 is greater than or equal to the length of the avoidance section 1018 extending along the circumference of the frame portion 101. In this way, it can be ensured that the grease and water stains on the wall surface of the boss 1011 where the bearing surface 10111 of the avoidance section 1018 is located can be timely guided to the sound-passing opening 10113 through the guide groove 10112, thereby preventing the grease and water stains accumulated in the gap 1003 between the light-transmitting cover plate 21 and the frame portion 101 from entering the interior of the display screen 2 through the sealed gap between the bearing surface 10111 of the avoidance section 1018 and the light-transmitting cover plate 21 to corrode the display screen 2.

[0141] Please continue reading Fig.16 A transition section 1019 is provided between the main body section 1017 and the avoidance section 1018. In the direction from the main body section 1017 to the avoidance section 1018, the inner wall surface of the transition section 1019 extends obliquely in the direction close to the frame portion 101. The inner wall surface of the transition section 1019 can be formed as a curved surface or a plane. By providing the transition section 1019 between the main body section 1017 and the avoidance section 1018, it is possible to avoid that the bearing surface 10111 of the main body section 1017 and the bearing surface 10111 of the avoidance section 1018 change too much at the connection between the main body section 1017 and the avoidance section 1018, and it is not easy to glue at the connection. In addition, by providing the transition section 1019 between the main body section 1017 and the avoidance section 1018, the connection strength between the main body section 1017 and the avoidance section 1018 can also be improved.

[0142] See also Figure 16-Figure 17 A dam glue 7 is provided between the inner wall surface of the boss 1011 and the display module 22, one end of the dam glue 7 is connected to the circumferential end of the side sealing glue 6, and the other end of the dam glue 7 extends in a direction away from the side sealing glue 6. One end of the dam glue 7 can extend to the inner side of the inner wall surface of the avoidance section 1018, and the other end of the dam glue 7 can extend to the inner side of the inner wall surface of the main body section 1017.

[0143] By providing the dam glue 7 connected to the side sealant 6 between the inner wall surface of the boss 1011 and the display module 22, a sealing structure is formed at the connection between the side sealant 6 and the dam glue 7, and grease and water stains cannot enter the inside of the electronic device 100 through the connection between the side sealant 6 and the dam glue 7, thereby providing better protection for the electronic device 100. Exemplarily, the side sealant 6 and the dam glue 7 can be hot melt adhesive.

[0144] In addition, the electronic device 100 may also be provided with a camera assembly. For example, a front camera assembly is generally provided near the sound-passing gap 1001 of the electronic device 100. In order to prevent external grease or water stains from corroding the front camera assembly, a foam 8 is generally provided on the periphery of the front camera assembly. Figure 16-Figure 17 The foam 8 is arranged between the display module 22 and the middle plate 102 and surrounds the outer periphery of the front camera assembly (not shown in the figure). By arranging the foam 8, grease and water stains that enter the electronic device 100 through the sound-passing gap 1001 can be prevented from corroding the front camera assembly.

[0145] The foam 8 can be a closed-cell foam, a semi-closed-cell foam or an open-cell foam, which is not limited in the present embodiment. Among them, the closed-cell foam and the semi-closed-cell foam have strong resilience and retention.

[0146] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.
