Description

Technical Field

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

[0002] With the development of society, the popularity of mobile phones is getting higher and higher, and the replacement cycle is getting longer and longer, so the protection requirements and sophistication requirements for mobile phones are also getting higher and higher. In order to achieve an ultra-high screen-to-body ratio, a narrow slit sound outlet solution is adopted at the earpiece. However, external water stains (such as user sweat), oil stains and impurities can easily enter the interior of the whole machine from the narrow slit sound outlet. When external water stains, oil stains and impurities come into contact with the display panel, the display surface may not display normally, affecting the user experience. Summary of the invention

[0003] An embodiment of the present application provides an electronic device for protecting a display panel in a display screen from interference from external interference sources such as water stains and oil stains, thereby increasing the service life of the display screen.

[0004] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0006] In this way, the first colloid, the second colloid, the third colloid and the fourth colloid together form a protection for protecting the circumferential side of the display panel from the erosion of interference sources such as water stains and oil stains in the sound outlet channel. Specifically, after the interference sources such as water stains and oil stains enter the electronic device through the sound outlet channel, a part of the interference sources will diffuse toward the first area.

Another part of the interference sources will diffuse toward both sides of the sound outlet channel, and another part of the interference sources diffused toward both sides of the sound outlet channel will be blocked by the second colloid, the third colloid and the fourth colloid. In summary, the interference sources entering the electronic device from the sound outlet channel will be blocked by the first colloid, the second colloid, the third colloid and the fourth colloid, and will not diffuse to the circumferential side of the display panel, thereby preventing the circumferential side of the display panel from being eroded by interference sources such as water stains and oil stains in the sound outlet channel while ensuring that the sound outlet channel is well output.

[0007] In addition, by setting the fourth colloid, the cover plate and the frame can be sealed to prevent interference sources such as water stains and oil stains in the environment from entering the interior of the electronic device through the avoidance gap between the cover plate and the frame.

[0041] This application provides an electronic device, see Figure 1 , Figure 1 A schematic diagram of the structure of an electronic device provided for some embodiments of the present application. The electronic device 100 is a type of electronic device 100 in which the earpiece 110 uses a narrow slit to emit sound. The electronic device 100 may be a user equipment (UE) or a terminal device, etc. For example, the electronic device 100 may be a large-screen display terminal, a personal digital assistant (PDA), a handheld device with a wireless communication function, a computing device, a vehicle-mounted device, a wearable device, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a display terminal in industrial control, a display terminal in self-driving, a display terminal in remote medical, a display terminal in a smart grid, a display terminal in transportation safety, a display terminal in a smart city, and a display terminal in a smart home. Among them, the large-screen display terminal includes but is not limited to a smart screen, a portable android device (PAD), a laptop computer, a desktop computer, a television, a projector and other devices.

[0042] Please continue reading Figure 1 , this embodiment and the following embodiments are exemplified by taking the electronic device 100 as a mobile phone. The electronic device 100 is approximately in the shape of a rectangular plate. On this basis, in order to facilitate the description of the following embodiments, an XYZ coordinate system is established, and the width direction of the electronic device 100 is defined as the X-axis direction, the length direction of the electronic device 100 is defined as the Y-axis direction, and the thickness direction of the electronic device 100 is defined as the Z-axis direction. It can be understood that the coordinate system setting of the electronic device 100 can be flexibly set according to actual needs, and no specific limitation is made here. In some other embodiments, the shape of the electronic device 100 can also be a square flat plate, a circular flat plate, an elliptical flat plate, etc., which are not specifically limited here.

[0043] In some embodiments of this application, please continue to refer to Figure 1 , the electronic device 100 includes a display screen 120 .

[0044] Understandably, Figure 1 Only some components of the electronic device are schematically shown, and the actual shapes, sizes, positions and structures of these components are not subject to Figure 1 restrictions.

[0045] The display screen 120 is used to display images, videos, etc. The display screen 120 may be a 3D display screen or a 2.5D display screen, etc. ( Figure 1 The display screen 120 shown in FIG. 1 is a 3D display screen). Figure 2 and Figure 3 , Figure 2 for Figure 1 A cross-sectional view of the electronic device shown in FIG. 1 at AA; Figure 3 for Figure 2 The display screen 120 may include a cover plate 121 and a display panel 122. The cover plate 121 is stacked with the display panel 122, and the cover plate 121 is located on the display side of the display panel 122 (for example, Figure 3 The cover plate 121 shown in the figure is located on one side of the display panel 122 in the positive direction of the Z axis), that is, when the user uses the electronic device, the cover plate 121 faces the user.

[0046] The area of ​​the cover plate 121 is larger than the area of ​​the display panel 122, and the circumferential side of the cover plate 121 protrudes from the circumferential side of the display panel 122. The cover plate 121 completely covers the display panel 122, and the cover plate 121 is mainly used to protect the display panel 122 and prevent dust. The material of the cover plate 121 includes but is not limited to glass. The cover plate 121 also has the functions of anti-impact, scratch-resistant, oil-resistant, anti-fingerprint, and enhanced light transmittance.

[0047] The display panel 122 may be a flexible display panel or a rigid display panel. For example, the display panel 122 may be an organic light-emitting diode (OLED) display panel, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display panel, a mini organic light-emitting diode (MILLED) display panel, a micro organic light-emitting diode (MILLED) display panel, a micro organic light-emitting diode (MILLED) display panel, a quantum dot light-emitting diode (QLED) display panel, a liquid crystal display (LCD) panel, etc.

[0048] Please continue reading Figure 3 The electronic device 100 may further include a back shell 130 and a middle frame 140. The back shell 130 and the middle frame 140 together form a housing of the electronic device 100, and are used to protect the internal electronic components of the electronic device 100. The back shell 130 is located on a side of the display panel 122 away from the cover plate 121 (for example, Figure 3 The middle frame 140 is located on the side of the negative Z direction of the display panel 122 shown in the figure), and is stacked and spaced apart with the cover plate 121 and the display panel 122. The middle frame 140 is located between the back shell 130 and the cover plate 121. The back shell 130 is fixed to the middle frame 140. Exemplarily, the back shell 130 can be fixedly connected to the middle frame 140 by adhesive. The middle frame 140 can also be an integrally formed structure with the back shell 130, that is, the middle frame 140 and the back shell 130 are a whole structural component. The cover plate 121, the back shell 130 and the middle frame 140 form a housing cavity of the electronic device 100. The housing cavity accommodates the display panel 122, the circuit board, the camera, the flash and the earpiece 110.

[0049] In some embodiments of the present application, the electronic device 100 is taken as a mobile phone as an example. Figures 3 to 5 , Figure 4 for Figure 1 A partial schematic diagram of the electronic device shown in ; Figure 5 Schematic diagram of the middle frame of the electronic device provided in some other embodiments of the present application. In order to achieve an ultra-high screen-to-body ratio of the mobile phone, a narrow slit is used for the earpiece of the mobile phone to emit sound. The earpiece refers to the earpiece when the user is talking, which is generally located at the top of the display screen 120 (for example, the earpiece is set at Figure 4The display screen 120 shown in the figure is located on the side of the positive direction of the Y axis). Specifically, the middle frame 140 includes a frame 141, and a first boss 1421 and a second boss 1422 are arranged on the inner circumference of the frame 141. The first boss 1421 and the second boss 1422 both extend along the circumference of the inner circumference of the frame 141. The first boss 1421 and the second boss 1422 are spaced apart. The display screen 120, the frame 141, the first boss 1421 and the second boss 1422 jointly form a sound outlet channel 150; the cover plate 121 includes a second side surface 1211 close to the earpiece, and the second side surface 1211 is provided with an avoidance notch 1212. Specifically, the avoidance notch 1212 is located in the middle position of the second side surface 1211 and is formed by being recessed toward the negative direction of the Y axis. The avoidance notch 1212 is connected to the sound outlet channel 150.

[0050] In other embodiments, the avoidance gap can also be formed on the frame. Specifically, a avoidance gap 1212 can be opened on the side of the frame on the same side as the second side 1211. The avoidance gap 1212 can be a through groove that connects the sound outlet channel 150 with the outside.

[0051] The sound of a mobile phone call is emitted from the handset in the receiving cavity, propagates to the outside of the mobile phone through the sound outlet channel 150, and then is transmitted to the user's ear. Therefore, by providing the sound outlet channel 150, there is no need to separately provide a sound outlet hole for sound on the display screen 120, thereby achieving the purpose of increasing the screen ratio of the display screen 120.

[0052] However, to ensure that the user can clearly hear the sound from the handset, please refer to Figure 3 , the sound output channel 150 is generally not equipped with physical protection. Figure 3 In the path shown by the middle arrow, when the user uses the mobile phone, the sweat on the user's hands or ears can easily enter the inside of the mobile phone from the position of the sound outlet channel 150, so that the sweat contacts the display panel 122, affecting the normal operation of the display panel 122 and the user's experience. Another solution is to set a nano-coating at the sound outlet channel 150. However, after the electronic device is used for a long time, the nano-coating will be corroded by water stains such as moisture in the environment, and the protection effect is not good.

[0053] It is understandable that during the use of the electronic device, the user's sweat and water stains such as moisture in the external environment can easily enter the interior of the electronic device through the sound outlet channel 150, and be transferred to the display panel 122 through the sound outlet channel 150, causing the display panel 122 to be unable to be used normally. Among them, the display panel 122 includes multiple sub-functional layers, and the multiple sub-functional layers are stacked. Therefore, the circumferential side of the display panel 122 is composed of the circumferential side of the multiple sub-functional layers. The sweat or water stains that diffuse to the circumferential side of the display panel 122 can easily enter the interior of the display panel 122 through the gaps between adjacent sub-functional layers. Therefore, the circumferential side of the display panel 122 is very susceptible to erosion by water stains and sweat.

[0054] Specifically, the functional layer in the display panel 122 may include a polarizer (POL), on which a polyvinyl alcohol (PVA) film is disposed. When sweat contacts the PVA layer, the edge of the POL layer will lack red in the polarization process, causing yellowing and affecting the user experience.

[0055] To solve the above technical problems, please refer to Figures 5 to 7 , Figure 6 Schematic diagram of a display screen of an electronic device provided in some other embodiments of the present application; Figure 7 Cross-sectional views of electronic devices provided for some other embodiments of the present application.

[0056] The present application provides a colloid electronic device, wherein a boss 142 is provided on the inner circumference of a frame 141 of the electronic device, and the boss 142 may include a first boss 1421 and a second boss 1422. The first boss 1421 is located at one end of a sound outlet channel 150 (e.g. Figure 5 The second boss 1422 is located at the other end of the sound outlet channel 150 (eg, Figure 5 The first boss 1421 includes a first side wall surface 1421a away from the frame 141, and the second boss 1422 includes a second side wall surface 1422a away from the frame 141.

[0057] The display panel 122 includes a first side surface 1221 , and the first side surface 1221 and the second side surface 1211 face the same direction (eg Figure 7 The second side surface and the first side surface shown in the figure are both located on the side of the display screen in the positive direction of the Y axis), the first side surface 1221 includes a first area 1222, and the first area 1222 is the area of ​​the first side surface 1211 corresponding to the sound output channel 150 (for example Figure 6Generally, the sound outlet channel 150 is located in the middle of the second side 1211, and the length of the sound outlet channel 150 is generally 1 / 5-1 / 3 of the length of the second side 1211. Specifically, the length of the sound outlet channel 150 may be 1 / 3, 1 / 4 or 1 / 5 of the length of the second side 1211. The first area 1222 is located in the middle of the second side 1211, and the length of the first area 1222 is greater than the length of the sound outlet channel 150. The sound outlet channel 150 includes a portion of the first area 1222 located in the middle of the second side 1211 (e.g. Figure 5 The orthographic projection of the first edge on the plane where the first area 1222 is located is located in the first area 1222, and the orthographic projection of the second edge on the plane where the first area 1222 is located is located in the first area 1222, that is, both ends of the first area 1222 exceed the two ends of the sound outlet channel 150 (the first edge and the second edge).

[0058] See also Figures 6 to 8 , Figure 8 Schematic diagram of an electronic device provided by some embodiments of the present application. A first colloid 161 is disposed on the first area 1222, a second colloid 1621 is disposed between the display screen 120 and the first side wall surface 1421a, a third colloid 1622 is disposed between the display screen 120 and the second side wall surface 1422a, and a fourth colloid 163 is disposed between the display screen 120 and the inner peripheral surface of the frame 141.

[0059] Among them, one end of the first colloid 161 is sealed and connected to the second colloid 1621, so that the water stains diffused to the connection between the first colloid 161 and the second colloid 1621 cannot enter the inside of the electronic device through the connection between the first colloid 161 and the second colloid 1621; the second colloid 1621 is sealed and connected to the fourth colloid 163, so that the water stains diffused to the connection between the second colloid 1621 and the fourth colloid 163 cannot enter the inside of the electronic device through the connection between the second colloid 1621 and the fourth colloid 163. The other end of the first colloid 161 is sealed and connected to the third colloid 1622, so that the water diffused to the connection between the first colloid 161 and the third colloid 1622 cannot enter the inside of the electronic device through the connection between the first colloid 161 and the third colloid 1622; the third colloid 1622 is sealed and connected to the fourth colloid 163, so that the water diffused to the connection between the third colloid 1622 and the fourth colloid 163 cannot enter the inside of the electronic device.

[0060] In this way, the first colloid 161, the second colloid 1621, the third colloid 1622 and the fourth colloid 163 together form a colloid protection for protecting the circumferential side of the display panel 122 from being corroded by water stains in the sound outlet channel 150. For details, please refer to Figure 8As shown by the arrow in the middle, after the water stains enter the electronic device 100 through the sound outlet channel 150, part of the water stains will diffuse toward the first area 1222. By setting the first colloid 161 on the first area 1222, the first area 1222 is protected from the erosion of the water stains. The other part of the sweat will diffuse toward the two sides of the sound outlet channel 150 (for example, Figure 8 The sound outlet channel 150 shown in the figure diffuses on both sides of the X-axis direction), and another part of the sweat diffused toward both sides of the sound outlet channel 150 will be blocked by the second colloid 1621, the third colloid 1622 and the fourth colloid 163.

[0061] In summary, the sweat entering the electronic device 100 through the sound outlet channel 150 will be blocked by the first colloid 161, the second colloid 1621, the third colloid 1622 and the fourth colloid 163, and will not spread to the circumferential side of the display panel 122. Therefore, the circumferential side of the display panel 122 is prevented from being corroded by water stains in the sound outlet channel 150 while ensuring that the electronic device can sound well.

[0062] In addition, by providing the fourth colloid 163, the cover plate 121 and the frame 141 can be sealed to prevent moisture in the environment from entering the interior of the electronic device 100 through the gap between the cover plate 121 and the frame 141. The second colloid 1621 is connected to the fourth colloid 163, and the third colloid 1622 is connected to the fourth colloid 163, which can better ensure the sealing between the cover plate 121 and the frame 141. In this way, the normal use of the electronic device 100 is fully guaranteed, and the user experience is improved.

[0063] In some embodiments of the present application, one end of the first boss 1421 facing away from the sound outlet channel 150 is connected to one end of the second boss 1422 facing away from the sound outlet channel 150 .

[0064] In some embodiments of this application, please refer to Fig. 9 , and combined with Figure 7 , Fig. 9 for Figure 6 The bottom view of the display screen shown in FIG. The display screen 120 may further include a functional layer 123. Specifically, the functional layer 123 may be a copper foil layer. The copper foil layer plays a role in shielding electromagnetic interference in the display screen 120. The copper foil layer is stacked with the display panel 122. The copper foil layer is located on the side of the display panel 122 away from the cover plate 121. The circumferential side of the display panel 122 protrudes from the circumferential side of the copper foil layer. The copper foil layer and the display panel 122 are bonded by a mesh adhesive. A foam layer may also be provided on the side of the copper foil layer facing the display panel 122 to avoid hard collision between the copper foil layer and the display panel 122.

[0065] The display panel 122 may further include a second area 1223, the second area 1223 is located on a side surface of the display panel 122 away from the cover plate 121, the second area 1223 is exposed from the functional layer, and the second area 1223 is connected to the first area 1222; the first colloid 161 covers the first area 1222 and the second area 1223. In this way, the first colloid 161 can cover the area of ​​the display panel 122 exposed to the sound outlet channel 150, thereby fully protecting the display panel 122.

[0066] Understandably, please refer to Fig.10 , Fig.10 Schematic diagram of the sound output channel of an electronic device provided in some other embodiments of the present application. Fig.10 In the path indicated by the middle arrow, the second area 1223 of the display panel 122 is exposed to the space of the sound outlet channel 150. The sweat and water vapor entering the sound outlet channel 150 from the outside will contact the second area 1223. Since there are multiple electronic components on the display panel 122, after the sweat spreads to the second area 1223, the display panel 122 may also be damaged. Therefore, the first colloid 161 is coated on the second area 1223, so that the second area 1223 connected to the first area 1222 on the display panel 122 can be covered, and the water vapor and sweat in the sound outlet channel 150 can be blocked from eroding the second area 1223, thereby providing more comprehensive protection for the display panel 122, so that the display panel 122 is protected from the sweat and water vapor in the sound outlet channel 150.

[0067] The first colloid 161 may include a first portion 1611, the first portion 1611 is disposed in the first area 1222, and the maximum value of the thickness of the first portion 1611 is less than or equal to the distance from the second side 1211 to the first side 1221. It should be noted that the first colloid 161 is dispensed by a dispensing machine, and during the entire dispensing process, the dispensing machine cannot ensure that the dispensing thickness is exactly the same. When the maximum value of the thickness of the first portion 1611 is less than or equal to the distance from the second side 1211 to the first side 1221, it means that the thickness of the first portion 1611 is less than or equal to the distance from the second side 1211 to the first side 1221. That is, the first portion 1611 will not protrude from the second side 1211, and the user will not observe the first colloid 161 when observing the inside of the electronic device 100 from the avoidance gap, thereby improving the product quality of the electronic device, ensuring the overall beauty of the electronic device 100, and improving the user's experience.

[0068] The first colloid 161 may further include a second portion 1612, the second portion 1612 being disposed in the second region 1223, and the maximum value of the thickness of the second portion 1612 being less than or equal to the thickness of the functional layer 123. In other words, the thickness of the second portion 1612 is less than or equal to the thickness of the functional layer 123. That is, the second portion 1612 does not protrude from the bottom surface of the functional layer 123. It should be noted that the second colloid 1621 and the third colloid 1622 abut against the bottom surface of the functional layer 123, and the second colloid 1621 and the third colloid 1622 exert a certain stress on the functional layer 123. When the second portion 1612 protrudes from the bottom surface of the functional layer 123, the second portion 1612 of the first colloid 161 will occupy the space of the second colloid 1621 and the third colloid 1622, resulting in an increase in the stress of the second colloid 1621 and the third colloid 1622 on the functional layer 123, so that the functional layer 123 is at risk of deformation. Therefore, by limiting the maximum value of the thickness of the second portion 1612 to be less than or equal to the thickness of the functional layer 123 , the deformation of the functional layer 123 due to the above reasons can be avoided.

[0069] The first colloid 161 is made of hot melt adhesive. When the electronic device 100 is used for a long time and the first colloid 161 is damaged, the display screen 120 can be removed from the middle frame 140, and then the first colloid 161 is heated. Since the first colloid 161 is hot melt adhesive, it can be removed after heating and re-applied with new hot melt adhesive.

[0070] In some embodiments of the present application, the first portion 1611 and the second portion 1612 of the first colloid 161 are connected.

[0071] In some embodiments of this application, please continue to refer to Figure 8 The second colloid 1621 is located on one side of the sound output channel 150 (eg Figure 8 The sound outlet channel 150 is on one side of the negative direction of the X axis as shown in FIG. 1 ), and the third colloid 1622 is located on the other side of the sound outlet channel 150 (eg Figure 8 The sound outlet channel 150 shown in FIG. 1 is on the side of the positive direction of the X-axis).

[0072] In this way, on the one hand, the second colloid 1621 can avoid the sound output channel 150, avoiding the phenomenon that the second colloid 1621 and the third colloid 1622 block the sound output channel 150, and ensuring the normal sound output of the sound output channel 150. On the other hand, the usage of the second colloid 1621 and the third colloid 1622 can be reduced, thereby reducing the production cost of the electronic device 100, reducing the overall weight of the electronic device 100, and improving the user's feel.

[0073] The second colloid 1621 and one end of the first colloid 161 (eg Figure 8The first colloid 161 shown in the figure is connected at one end in the negative direction of the X-axis, thereby, water diffused to the connection between the second colloid 1621 and the first colloid 161 cannot enter the interior of the electronic device through the connection between the second colloid 1621 and the first colloid 161; the second colloid 1621 is connected to the fourth colloid 163, thereby, water at the connection between the second colloid 1621 and the fourth colloid 163 cannot enter the interior of the electronic device through the connection between the second colloid 1621 and the fourth colloid 163.

[0074] The third colloid 1622 is connected to the other end of the first colloid 161 (eg Figure 8 The first colloid 161 shown in the figure is connected at one end in the positive direction of the X-axis, thereby, water stains diffused to the connection between the third colloid 1622 and the first colloid 161 cannot enter the interior of the electronic device through the connection between the third colloid 1622 and the first colloid 161; the third colloid is connected to the fourth colloid, thereby, water diffused to the connection between the third colloid 1622 and the fourth colloid 163 cannot enter the interior of the electronic device through the connection between the third colloid 1622 and the fourth colloid 163.

[0075] Please continue to refer to Figure 8 and Fig.10 The frame 141 may include a first frame 1411, a second frame 1412 and a third frame 1413. The first frame 1411 is disposed opposite to the second side surface 1211. One end of the first frame 1411 (eg Figure 8 The first frame 1411 shown in FIG. 1 is connected to the second frame 1412 at one end in the negative direction of the X axis. The other end of the first frame 1411 (eg Figure 8 The first frame 1411 shown in the figure at one end in the positive direction of the X-axis is connected to the third frame 1413; the second colloid 1621 forms an "L"-shaped colloid; and the third colloid 1622 forms an "L"-shaped colloid.

[0076] Specifically, the first boss includes a first sub-boss and a second sub-boss that are connected. The extension direction of the first sub-boss is parallel to the extension direction of the first frame 1411, and the extension direction of the second sub-boss is parallel to the extension direction of the second frame 1412. The first sub-boss includes a first sub-side wall surface facing away from the frame 141, and the second sub-boss includes a second sub-side wall surface facing away from the frame 141. The first sub-side wall surface and the second sub-side wall surface constitute a first side wall surface 1421a. The first glue segment 1621a is located between the first sub-side wall surface and the display screen 120, and the second glue segment 1621b is located between the second sub-side wall surface and the display screen 120. The first glue segment 1621a and the second glue segment 1621b are connected at the transition position between the first frame 1411 and the second frame 1412.

[0077] The second boss includes a third sub-boss and a fourth sub-boss connected to each other. The extension direction of the third sub-boss is parallel to the extension direction of the first frame 1411. The extension direction of the fourth sub-boss is parallel to the extension direction of the third frame 1413. The third sub-boss includes a third sub-side wall surface away from the frame 141. The fourth sub-boss includes a fourth sub-side wall surface away from the frame 141. The third sub-side wall surface and the fourth sub-side wall surface constitute the second side wall surface 1422a. The third colloid 1622 includes a third glue segment 1622a and a fourth glue segment 1622b connected to each other. The third glue segment 1622a is located between the third sub-side wall surface and the display screen 120. The fourth glue segment 1622b is located between the fourth sub-side wall surface and the display screen 120. The third glue segment 1622a and the fourth glue segment 1622b are connected at the transition position between the first frame 1411 and the third frame 1413.

[0078] It should be noted that, relative to the straight fourth colloid 163 on the first frame 1411, the second frame 1412 and the third frame 1413, the connection position between the first frame 1411 and the second frame 1412 and the connection position between the first frame 1411 and the third frame 1413 are transition positions, and it is difficult to dispense glue at the transition position. Setting the second colloid 1621 as an "L"-shaped colloid can well wrap the transition position between the first frame 1411 and the second frame 1412; setting the third colloid 1622 as an "L"-shaped colloid can well wrap the transition position between the first frame 1411 and the third frame 1413.

[0079] Specifically, refer to Figure 8 , wherein the frame 141 is rounded at the transition position, and the cover plate is also rounded at the transition position, and the two rounded corners cooperate with each other, and the size of the rounded corners can be determined according to the size of the electronic device and specific design requirements. It is difficult to ensure the accuracy of the connection between the cover plate and the frame at the transition position, which makes it difficult to dispense the fourth colloid 163 at the transition position, and the sealing of the transition position cannot be guaranteed.

[0080] However, the glue dispensing amount per unit time of the glue dispensing machine is generally fixed. And when the fourth colloid 163 is set at the transition position, the glue dispensing machine needs to change direction continuously. Therefore, it is difficult to ensure the sealing of the fourth colloid 163 at the transition position. By setting the "L"-shaped second colloid 1621 and the third colloid 1622, the processing error between the frame 141 and the cover plate at the transition position can be compensated, and a glue dispensing space with a stable size is provided for the dispensing of the fourth colloid 163, thereby ensuring the stability of the fit between the cover plate and the frame 141 after the fourth colloid 163 is dispensed.

[0081] At the same time, reference Figure 8According to the arrow path in the figure, at the transition position between the first frame 1411 and the second frame 1412, and at the transition position between the first frame 1411 and the third frame 1413, it is highly likely that water vapor and other water stains from the external environment enter the interior of the electronic device. Therefore, by setting the second colloid 1621 at the transition position between the first frame 1411 and the second frame 1412, setting the third colloid 1622 at the transition position between the first frame 1411 and the third frame 1413, and then setting the fourth colloid 163, the sealing of the transition position can be better ensured, thereby preventing water stains such as sweat and moisture in the external environment from entering the interior of the electronic device, better protecting the electrical components inside the electronic device, and improving product quality.

[0082] Specifically, in some embodiments, the material of the second colloid 1621 and the third colloid 1622 can be silica gel. Colloids made of silica gel have the advantages of good electrical insulation performance, not easy to age, high adsorption performance, good thermal stability, and stable chemical properties.

[0083] In some embodiments of this application, please continue to refer to Figures 8 to 10 The middle frame 140 may further include a middle plate 145 , and the frame 141 is connected to the circumferential edge of the middle plate 145 ; the electronic device may further include a fifth colloid 164 , which is disposed between the display screen 120 and the middle plate 145 and is used to bond the display screen 120 to the middle plate 145 .

[0084] The fifth colloid 164 includes a first end facing the sound output channel, the second colloid 1621 is sealed and connected to the first end of the fifth colloid 164 , and the third colloid 1622 is sealed and connected to the first end of the fifth colloid 164 .

[0085] Specifically, on the one hand, the middle plate 145 includes a supporting surface 1451 facing the display screen 120, and the fifth colloid 164 is arranged on the side surface of the display screen 120 facing the supporting surface 1451. By setting the fifth colloid 164 between the display screen 120 and the middle plate 145, the display screen 120 is fixed on the middle plate 145 of the middle frame 140.

[0086] On the other hand, the first end of the fifth colloid 164 is connected to the second colloid 1621 and the third colloid 1622 respectively, which can avoid the formation of a gap between the second colloid 1621 and the fifth colloid 164, and avoid the formation of a gap between the third colloid 1622 and the fifth colloid 164, so that water stains in the environment cannot enter between the display screen 120 and the middle plate 145 through the gap between the second colloid 1621 and the fifth colloid 164 and the gap between the third colloid 1622 and the fifth colloid 164, thereby affecting the normal use of the electronic device.

[0087] In some embodiments of the present application, the fourth colloid 163 and the fifth colloid 164 may also be made of hot melt adhesive. In this way, when the electronic device needs to be maintained inside during long-term use, it is only necessary to heat the fourth colloid 163 to separate the display screen 120 from the frame 141, and then heat the fifth colloid 164 to separate the display screen 120 from the middle frame 140, so that the inside of the electronic device can be maintained.

[0088] Please continue reading Fig.10 The path indicated by the arrow, the sweat and water stains that enter from the sound outlet channel 150 and spread to the side of the functional layer 123 away from the cover plate 121, will be blocked by the fifth colloid 164, further preventing the water stains that enter from the sound outlet channel 150 from entering the interior of the electronic device. In this way, the electronic device can be better protected by the first colloid 161, the second colloid 1621, the third colloid 1622, the fourth colloid 163 and the fifth colloid 164 that cooperate with each other.

[0089] In some embodiments of this application, please refer to Fig.11 , Fig.11 A partial schematic diagram of a middle frame provided in some other embodiments of the present application. A first avoidance space 143 is provided between the first boss 1421 and the sound outlet channel 150, and a second avoidance space 144 is provided between the second boss 1422 and the sound outlet channel 150. The first boss 1421 is provided on one side of the sound outlet channel 150 (for example, Fig.11 The sound outlet channel 150 is shown on the negative side of the X-axis), there is a certain distance between the first boss 1421 and the sound outlet channel 150 and no boss is provided, and the space between the first boss 1421 and the sound outlet channel 150 is the first avoidance space 143.

[0090] Similarly, the second boss 1422 is located at the other side of the sound outlet channel 150 (eg Fig.11 The sound outlet channel 150 shown in the figure is on one side of the positive direction of the X-axis), there is a certain distance between the second boss 1422 and the sound outlet channel 150 and no boss is provided, and the space between the second boss 1422 and the sound outlet channel 150 is the second avoidance space 144.

[0091] It should be noted that the first colloid, the second colloid and the fourth colloid are connected at the position of the first avoidance space, and the first avoidance space 143 is set up, which can increase the setting space of the first colloid, the second colloid and the fourth colloid in the first avoidance space 143, and then increase the amount of the first colloid, the second colloid and the fourth colloid in the first avoidance space 143, and then increase the stability of the connection between the first colloid, the second colloid and the fourth colloid in the first avoidance space 143, thereby ensuring the sealing between the first colloid, the second colloid and the fourth colloid, and preventing water stains in the external environment from entering the interior of the electronic device through the position where the first colloid, the second colloid and the fourth colloid are connected.

[0092] The first colloid, the third colloid and the fourth colloid are connected at the position of the second avoidance space, and the second avoidance space 143 is set up, which can increase the setting space of the first colloid, the third colloid and the fourth colloid in the second avoidance space 144, and then increase the stability of the connection between the first colloid, the third colloid and the fourth colloid in the second avoidance space 144, ensure the sealing between the first colloid, the third colloid and the fourth colloid, and prevent water stains in the external environment from entering the interior of the electronic device through the position where the first colloid, the third colloid and the fourth colloid are connected.

[0093] In this way, on the one hand, the first avoidance space 143 can improve the connection strength between the second colloid 1621, the first colloid 161 and the fourth colloid 163; the second avoidance space 143 can improve the connection strength between the third colloid 1622, the first colloid 161 and the fourth colloid 163. On the other hand, by providing the first avoidance space 143 and the second avoidance space 144, when the user uses the electronic device, the user can avoid seeing the boss through the avoidance gap, thereby improving the overall aesthetics of the electronic device and improving the user's experience.

[0094] In the specific dispensing process, please refer to Fig.12 and Fig.13 , Fig.12 Schematic diagram of dispensing a first colloid onto a display screen in some other embodiments of the present application; Fig.13 Schematic diagram of applying the second colloid, the third colloid, and the fourth colloid to the middle frame in other embodiments of the present application. First, apply the first colloid 161 to the corresponding position on the display screen 120; second, apply the second colloid 1621 and the third colloid 1622 to the corresponding position on the middle frame 140; third, apply the fourth colloid 163 to the corresponding position on the middle frame 140; finally, install the display screen 120 on the middle frame 140. A fifth colloid 164 is also provided between the display screen 120 and the middle frame 140.

[0095] Thus, by setting the first colloid 161, the second colloid 1621, the third colloid 1622, the fourth colloid 163 and the fifth colloid 164 that cooperate with each other, the second colloid 1621 is connected to the first colloid 161, the second colloid 1621 is connected to the fourth colloid 163, the second colloid 1621 is connected to the fifth colloid 164; the third colloid 1622 is connected to the first colloid 161, the third colloid 1622 is connected to the fourth colloid 163, and the third colloid 1622 is connected to the fifth colloid 164. In this way, the electronic equipment is fully protected, moisture in the external environment is prevented from entering the interior of the electronic equipment, and the electronic components inside the electronic equipment are prevented from being corroded.
