Abstract
Description
Technical Field
[0001] This application relates to the field of electronic product technology, and more particularly to an electronic device. Background Technology
[0002] With societal development, mobile phone penetration is increasing, and replacement cycles are becoming longer. Consequently, the demands for mobile phone protection and sophistication are also rising. To achieve an ultra-high screen-to-body ratio, a narrow slit is used for sound output at the earpiece. However, external factors such as water (e.g., user sweat), oil, and impurities can easily enter the device through this slit. When these substances come into contact with the display panel, they may cause display issues, affecting the user experience. Summary of the Invention
[0003] This application provides an electronic device for protecting the display panel in a display screen from interference from external sources such as water stains and oil, thereby improving the lifespan of the display screen.
[0004] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:
[0005] This application provides an electronic device, comprising: a display screen and a mid-frame; the display screen includes a cover plate and a display panel, the cover plate being located on the display side of the display panel, and the circumferential side of the cover plate protruding beyond the circumferential side of the display panel; the display screen is mounted on the mid-frame, the mid-frame including a frame, a first protrusion and a second protrusion being provided on the inner circumferential surface of the frame, both the first protrusion and the second protrusion extending circumferentially along the inner circumferential surface of the frame, the first protrusion and the second protrusion being spaced apart, and the display screen, the frame, the first protrusion and the second protrusion together forming a sound channel; the first protrusion includes a first sidewall facing away from the frame, and the second protrusion includes... The second side wall facing away from the frame; the display panel includes a first side, which is the side of the display panel facing the sound channel, and the first side includes a first area, which is the area of the first side corresponding to the sound channel; a first adhesive is provided on the first area, a second adhesive is provided between the display screen and the first side wall, a third adhesive is provided between the display screen and the second side wall, and a fourth adhesive is provided between the display screen and the inner peripheral surface of the frame, one end of the first adhesive is connected to the second adhesive, the other end of the first adhesive is connected to the third adhesive, the second adhesive is connected to the fourth adhesive, and the third adhesive is connected to the fourth adhesive.
[0006] In this way, the first, second, third, and fourth colloids together form a protective barrier, protecting the circumferential sides of the display panel from interference sources such as water stains and oil in the sound output channel. Specifically, after water stains, oil, and other interference sources enter the electronic device through the sound output channel, some of the interference sources diffuse towards the first area. By placing the first colloid on the first area, this prevents the first area from being corroded by the interference sources. Another portion of the interference sources diffuses towards both sides of the sound output channel, and this third portion is blocked by the second, third, and fourth colloids. In summary, interference sources entering the electronic device through the sound output channel are blocked by the first, second, third, and fourth colloids, preventing them from diffusing to the circumferential sides of the display panel. This ensures good sound output from the sound output channel while preventing the circumferential sides of the display panel from being corroded by water stains, oil, and other interference sources in the sound output channel.
[0007] Furthermore, by incorporating a fourth adhesive layer, the cover plate and frame can be sealed together, preventing water stains, oil, and other environmental contaminants from entering the electronic device through the clearance between the cover plate and frame. Connecting the second and third adhesive layers to the fourth adhesive layer further enhances the seal between the cover plate and frame. This comprehensively ensures the normal operation of the electronic device and improves the user experience.
[0008] In one possible implementation of this application, the display screen further includes a functional layer located on the side of the display panel facing away from the cover plate, with the circumferential side of the display panel protruding beyond the circumferential side of the functional layer. The display panel also includes a second region located on the surface of the display panel facing the functional layer, exposed above the functional layer, and connected to the first region. Both the first and second regions are provided with a first adhesive. Therefore, by providing the first adhesive on the second region, the second region of the display panel can be protected from interference sources such as water stains and oil in the sound output channel, thus providing more comprehensive protection for the display panel.
[0009] In one possible implementation of this application, the cover plate includes a second side surface facing the same direction as the first side surface. The first adhesive includes a first portion disposed in a first region, the maximum thickness of which is less than or equal to the distance from the first side surface to the second side surface. This way, when a user looks into the electronic device from the clearance notch, the first adhesive will not be exposed, thus ensuring the overall aesthetics of the electronic device.
[0010] In one possible implementation of this application, the first colloid further includes a second portion disposed in the second region, the maximum thickness of which is less than or equal to the thickness of the functional layer. This reduces the stress between the second colloid and the functional layer, preventing the second colloid from pressing against the copper foil layer and causing deformation of the functional layer.
[0011] In one possible implementation of this application, the material of the first colloid is a hot melt adhesive.
[0012] In one possible implementation of this application, the frame includes a first frame, a second frame, and a third frame. The first frame is disposed opposite to a first side surface. One end of the first frame is connected to the second frame, and the other end is connected to the third frame. The first boss includes a first sub-boss and a second sub-boss connected together. The extension direction of the first sub-boss is parallel to the extension direction of the first frame, and the extension direction of the second sub-boss is parallel to the extension direction of the second frame. The first sub-boss includes a first sub-sidewall facing away from the frame, and the second sub-boss includes a second sub-sidewall facing away from the frame. The first sub-sidewall and the second sub-sidewall form a first sidewall. The second colloid includes a first adhesive segment and a second adhesive segment connected together. The first adhesive segment is located between the first sub-sidewall and the display screen, and the second adhesive segment is located between the second sub-sidewall and the display screen.
[0013] The second protrusion includes a connected third sub-protrusion and a fourth sub-protrusion. The extension direction of the third sub-protrusion is parallel to the extension direction of the first frame, and the extension direction of the fourth sub-protrusion is parallel to the extension direction of the third frame. The third sub-protrusion includes a third sub-sidewall facing away from the frame, and the fourth sub-protrusion includes a fourth sub-sidewall facing away from the frame. The third and fourth sub-sidewalls form the second sidewall. The third adhesive includes a connected third adhesive segment and a fourth adhesive segment. The third adhesive segment is located between the third sub-sidewall and the display screen, and the fourth adhesive segment is located between the fourth sub-sidewall and the display screen. This ensures the stability of the fourth adhesive segment at the connection points of the first and second frames, and at the connection points of the first and third frames, thus ensuring the stability of the connection between the cover plate and the middle frame.
[0014] In one possible implementation of this application, a first clearance space is provided between the first protrusion and the sound outlet channel, and the connection positions of the second colloid, the first colloid, and the fourth colloid are located within the first clearance space; a second clearance space is provided between the second protrusion and the sound outlet channel, and the connection positions of the third colloid, the first colloid, and the fourth colloid are located within the second clearance space. Thus, by providing the first clearance space, the amount of the first, second, and fourth colloids can be increased; by providing the second clearance space, the amount of the first, third, and fourth colloids can be increased, thereby ensuring the stability of the connection.
[0015] In one possible implementation of this application, the material of the second colloid is silicone.
[0016] In one possible implementation of this application, the third colloid is made of silicone.
[0017] In one possible implementation of this application, the mid-frame further includes a mid-plate, with a frame connected to the circumferential edge of the mid-plate; the electronic device further includes a fifth adhesive, disposed between the display screen and the mid-plate, for bonding the display screen to the mid-plate. Thus, by providing the fifth adhesive, the display screen is fixed to the mid-frame.
[0018] In one possible implementation of this application, the fifth colloid includes a first end facing the sound outlet channel, the second colloid is connected to the first end of the fifth colloid, and the third colloid is connected to the first end of the fifth colloid. This ensures that moisture in the environment will not enter the interior of the electronic device through the connection between the third and fifth colloids.
[0019] In one possible implementation of this application, the first boss includes a first top surface facing away from the middle plate, the second boss includes a second top surface facing away from the middle plate, and the fourth colloid is disposed between the cover plate, the frame and the first top surface, and between the cover plate, the frame and the second top surface.
[0020] In one possible implementation of this application, the fourth adhesive is made of hot melt adhesive. Therefore, by setting the fourth adhesive as hot melt adhesive, it facilitates the removal of the cover plate.
[0021] In one possible implementation of this application, a clearance notch is provided on the cover plate, which connects the sound outlet channel with the outside.
[0022] In one possible implementation of this application, a clearance notch is provided on the frame, which connects the sound output channel to the outside world. Attached Figure Description

[0041] This application provides an electronic device; please refer to [link / reference]. Figure 1 , Figure 1 This is a schematic diagram of the structure of an electronic device provided in some embodiments of this application. The electronic device 100 is a type of electronic device 100 that uses a narrow slit for sound output from the earpiece 110. The electronic device 100 can be user equipment (UE) or a terminal, etc. For example, the electronic device 100 can be a large-screen display terminal, a personal digital assistant (PDA), a handheld device with wireless communication capabilities, a computing device, an in-vehicle 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 care, a display terminal in a smart grid, a display terminal in transportation safety, a display terminal in a smart city, or a display terminal in a smart home. Among these, large-screen display terminals include, but are not limited to, smart screens, portable Android devices (PADs), laptops, desktop computers, televisions, projectors, and other devices.
[0042] Please continue reading. Figure 1 In this embodiment and the following embodiments, the electronic device 100 is used as a mobile phone for illustrative purposes. The electronic device 100 is approximately rectangular in shape. Based on this, for the convenience of the description of the embodiments below, an XYZ coordinate system is established, defining the width direction of the electronic device 100 as the X-axis, the length direction of the electronic device 100 as the Y-axis, and the thickness direction of the electronic device 100 as the Z-axis. It is understood that the coordinate system setting of the electronic device 100 can be flexibly set according to actual needs, and is not specifically limited here. In some other embodiments, the shape of the electronic device 100 may also be a square plate, a circular plate, an elliptical plate, etc., and is not specifically limited here.
[0043] Please refer to some embodiments of this application. Figure 1 The electronic device 100 includes a display screen 120.
[0044] Understandable Figure 1 The electronic device is shown only schematically, and the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Restrictions.
[0045] The display screen 120 is used to display images, videos, etc., and can be a 3D display screen or a 2.5D display screen, etc. Figure 1 The display screen 120 shown is a 3D display screen. (See also...) Figure 2 and Figure 3 , Figure 2 for Figure 1 A cross-sectional view of the electronic device shown at point AA; Figure 3 for Figure 2 The enlarged view at point B shown. The display screen 120 may include a cover plate 121 and a display panel 122. The cover plate 121 is stacked on top of the display panel 122, and the cover plate 121 is located on the display side of the display panel 122 (e.g., Figure 3 The cover plate 121 shown is located on one side of the display panel 122 in the positive Z-axis direction, that is, when the user is using the electronic device, the cover plate 121 faces the user.
[0046] The cover plate 121 has a larger area than the display panel 122, and its circumferential sides protrude beyond those of the display panel 122. The cover plate 121 completely covers the display panel 122 and primarily serves to protect it from dust. The cover plate 121 may be made of materials including, but not limited to, glass. It also features impact resistance, scratch resistance, oil resistance, fingerprint resistance, and enhanced light transmittance.
[0047] The display panel 122 can be a flexible display panel or a rigid display panel. For example, the display panel 122 can be an organic light-emitting diode (OLED) display panel, an active-matrix organic light-emitting diode (AMOLED) display panel, a mini organic light-emitting diode (MLED) display panel, a micro organic light-emitting diode (MOLED) 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 cover 130 and a middle frame 140, the back cover 130 and the middle frame 140 together forming the housing of the electronic device 100, for protecting the internal electronic components of the electronic device 100. The back cover 130 is located on the side of the display panel 122 away from the cover plate 121 (e.g., Figure 3 The display panel 122 shown is located on the side with the negative Z direction, and is stacked and spaced apart from 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. For example, the back shell 130 can be fixed to the middle frame 140 by adhesive, or the middle frame 140 and the back shell 130 can be integrally formed, that is, the middle frame 140 and the back shell 130 are a single structural component. The cover plate 121, the back shell 130 and the middle frame 140 form a receiving cavity for the electronic device 100. This receiving cavity accommodates the display panel 122, the circuit board, the camera, the flash and the earpiece 110.
[0049] In some embodiments of this application, the electronic device 100 is taken as a mobile phone as an example. Please refer to [link / reference]. Figures 3 to 5 , Figure 4 for Figure 1 A partial schematic diagram of the electronic device shown; Figure 5 This is a schematic diagram of the mid-frame of an electronic device provided in other embodiments of this application. To achieve an ultra-high screen-to-body ratio, the earpiece of the phone uses a narrow slit for sound output. This earpiece refers to the one used during a user call, and is generally located at the top of the display screen 120 (e.g., the earpiece is positioned at...). Figure 4The display screen 120 shown is located on one side of the positive Y-axis direction. Specifically, the middle frame 140 includes a frame 141, and a first protrusion 1421 and a second protrusion 1422 are provided on the inner circumferential surface of the frame 141. The first protrusion 1421 and the second protrusion 1422 both extend circumferentially along the inner circumferential surface of the frame 141. The first protrusion 1421 and the second protrusion 1422 are spaced apart. The display screen 120, the frame 141, the first protrusion 1421 and the second protrusion 1422 together form a sound outlet channel 150. The cover plate 121 includes a second side 1211 near the earpiece. The second side 1211 is provided with a clearance notch 1212. Specifically, the clearance notch 1212 is located in the middle of the second side 1211 and is recessed in the negative Y-axis direction. The clearance notch 1212 communicates with the sound outlet channel 150.
[0050] In other embodiments, the clearance notch can also be formed on the frame. Specifically, a clearance notch 1212 can be formed on the side of the frame on the same side as the second side 1211. The clearance notch 1212 can be a through slot to connect the sound outlet channel 150 with the outside.
[0051] During a phone call, the sound is emitted from the earpiece inside the receiving cavity, propagated outside the phone via the sound outlet channel 150, and then transmitted to the user's ear. Therefore, by setting up the sound outlet channel 150, it is unnecessary to have a separate sound outlet on the display screen 120, thereby increasing the screen-to-body ratio of the display screen 120.
[0052] However, to ensure users can clearly hear the sound from the earpiece, please refer to... Figure 3 The output channel 150 generally does not have physical protection. Please refer to... Figure 3 As indicated by the middle arrow, during phone use, sweat from the user's hands or ears can easily enter the phone through the sound outlet channel 150, causing the sweat to come into contact with the display panel 122 and affecting its normal operation, thus impacting the user experience. Another solution is to install a nano-coating at the sound outlet channel 150; however, after prolonged use of electronic devices, the nano-coating can be corroded by moisture and other water stains in the environment, resulting in poor protective performance.
[0053] Understandably, during the use of electronic devices, user sweat and moisture from the external environment can easily enter the internal components of the electronic device through the sound output channel 150 and be transmitted to the display panel 122, causing the display panel 122 to malfunction. The display panel 122 comprises multiple sub-functional layers stacked on top of each other. Therefore, the circumferential side of the display panel 122 is composed of the circumferential side surfaces of multiple sub-functional layers. Sweat or water stains spreading to the circumferential side of the display panel 122 can easily enter the internal components of the display panel 122 through the gaps between adjacent sub-functional layers. Therefore, the circumferential side of the display panel 122 is highly susceptible to corrosion from water stains and sweat.
[0054] Specifically, the functional layer in the display panel 122 may include a polarizer (POL). The POL layer has a polyvinyl alcohol (PVA) film. When sweat comes into contact with the PVA layer, it will cause the polarization process at the edge of the POL layer to lack red, resulting in yellowing and affecting the user experience.
[0055] To resolve the above technical issues, please refer to Figures 5 to 7 , Figure 6 A schematic diagram of a display screen for an electronic device provided in other embodiments of this application; Figure 7 Cross-sectional view of an electronic device provided for other embodiments of this application.
[0056] This application provides a colloidal electronic device. A boss 142 is provided on the inner circumferential surface of the frame 141 of the electronic device. The boss 142 may include a first boss 1421 and a second boss 1422. The first boss 1421 is located at one end of the sound outlet channel 150 (e.g., Figure 5 The sound outlet channel 150 shown is located at one end in the negative X-axis direction, and the second boss 1422 is located at the other end of the sound outlet channel 150 (e.g., at one end in the negative X-axis direction). Figure 5 The sound outlet channel 150 shown is located at one end in the positive X-axis direction. The first boss 1421 includes a first side wall 1421a facing away from the frame 141, and the second boss 1422 includes a second side wall 1422a facing away from the frame 141.
[0057] The display panel 122 includes a first side 1221, which faces the same direction as the second side 1211 (e.g., ...). Figure 7 The second side and the first side shown are both located on one side of the display screen in the positive Y-axis direction. The first side 1221 includes a first region 1222, which is the region of the first side 1211 corresponding to the sound output channel 150 (e.g., Figure 6The first region 1222 shown in the diagram); generally, 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 to 1 / 3 of the length of the second side 1211. Specifically, the length of the sound outlet channel 150 can be 1 / 3, 1 / 4, or 1 / 5 of the length of the second side 1211. The first region 1222 is located in the middle of the second side 1211, and the length of the first region 1222 is greater than the length of the sound outlet channel 150. The sound outlet channel 150 includes the sound outlet channel in its length direction (e.g., Figure 5 The first edge and the second edge (in the X-axis direction shown) are located within the first region 1222, and the orthographic projection of the first edge onto the plane of the first region 1222 is also located within the first region 1222. That is, both ends of the first region 1222 extend beyond the two ends of the sound outlet channel 150 (the first edge and the second edge).
[0058] Please see Figures 6 to 8 , Figure 8 This is a schematic diagram of an electronic device provided in some embodiments of this application. A first colloid 161 is disposed on a first region 1222, a second colloid 1621 is disposed between the display screen 120 and the first side wall 1421a, a third colloid 1622 is disposed between the display screen 120 and the second side wall 1422a, and a fourth colloid 163 is disposed between the display screen 120 and the inner peripheral surface of the frame 141.
[0059] One end of the first colloid 161 is sealed to the second colloid 1621, thus preventing water that has diffused to the junction of the first colloid 161 and the second colloid 1621 from entering the electronic device through the junction. Similarly, the second colloid 1621 is sealed to the fourth colloid 163, preventing water that has diffused to the junction of the second colloid 1621 and the fourth colloid 163 from entering the electronic device through the junction. The other end of the first colloid 161 is sealed to the third colloid 1622, preventing water that has diffused to the junction of the first colloid 161 and the third colloid 1622 from entering the electronic device through the junction. Likewise, the third colloid 1622 is sealed to the fourth colloid 163, preventing water that has diffused to the junction of the third colloid 1622 and the fourth colloid 163 from entering the electronic device through the junction.
[0060] In this way, the first colloid 161, the second colloid 1621, the third colloid 1622, and the fourth colloid 163 together form a colloidal protection layer to protect the circumferential sides of the display panel 122 from water stains in the sound outlet channel 150. For details, please refer to... Figure 8As indicated by the middle arrow, after water enters the electronic device 100 through the sound outlet channel 150, some of the water will diffuse towards the first area 1222. By providing the first colloid 161 on the first area 1222, the first area 1222 is protected from water erosion. The remaining water will diffuse towards the sides of the sound outlet channel 150 (e.g.,...). Figure 8 The sound outlet channel 150 shown diffuses on both sides of the X-axis direction, and another part of the sweat that diffuses toward both sides of the sound outlet channel 150 is blocked by the second colloid 1621, the third colloid 1622 and the fourth colloid 163.
[0061] In summary, sweat entering the electronic device 100 through the sound output 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. Thus, while ensuring good sound output of the electronic device, the circumferential side of the display panel 122 will be protected from corrosion by water stains in the sound output channel 150.
[0062] Furthermore, by providing a fourth adhesive 163, the cover plate 121 and the frame 141 can be sealed, preventing moisture from the environment from entering the interior of the electronic device 100 through the gap between the cover plate 121 and the frame 141. Connecting the second adhesive 1621 to the fourth adhesive 163, and the third adhesive 1622 to the fourth adhesive 163, further ensures the airtightness between the cover plate 121 and the frame 141. This comprehensively ensures the normal operation of the electronic device 100 and improves the user experience.
[0063] In some embodiments of this application, the first boss 1421 is located away from the end of the sound outlet channel 150 and is connected to the second boss 1422 located away from the end of the sound outlet channel 150.
[0064] In some embodiments of this application, please refer to Figure 9 and combined Figure 7 , Figure 9 for Figure 6 The image shows a bottom view of the display screen. The display screen 120 may also include a functional layer 123. Specifically, the functional layer 123 may be a copper foil layer, which serves to shield electromagnetic interference in the display screen 120. The copper foil layer is stacked on top of the display panel 122, with the copper foil layer located on the side of the display panel 122 facing away from the cover plate 121. The circumferential side of the display panel 122 protrudes beyond the circumferential side of the copper foil layer. The copper foil layer and the display panel 122 are bonded together with a mesh adhesive. A foam layer may also be provided on the side of the copper foil layer facing the display panel 122 to prevent hard collisions between the copper foil layer and the display panel 122.
[0065] The display panel 122 may further include a second region 1223, which is located on the side of the display panel 122 facing away from the cover plate 121. The second region 1223 is exposed in the functional layer and is connected to the first region 1222. A first colloid 161 covers the first region 1222 and the second region 1223. In this way, the first colloid 161 can cover the area of the display panel 122 exposed to the sound channel 150, thereby providing comprehensive protection for the display panel 122.
[0066] Understandably, please refer to Figure 10 , Figure 10 This is a schematic diagram of the audio output channel of an electronic device provided in other embodiments of this application. (Refer to...) Figure 10 As 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. Sweat and moisture entering the sound outlet channel 150 from the outside will come into contact with the second area 1223. Since the display panel 122 has multiple electronic components, the display panel 122 may be damaged after sweat spreads to the second area 1223. Therefore, coating the second area 1223 with the first colloid 161 can cover the second area 1223 on the display panel 1222 that is connected to the first area 1222, preventing moisture and sweat in the sound outlet channel 150 from corroding the second area 1223, thereby providing more comprehensive protection for the display panel 122 and preventing the display panel 122 from being corroded by sweat and moisture in the sound outlet channel 150.
[0067] The first adhesive 161 may include a first portion 1611, which is disposed in the first region 1222. The maximum 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 adhesive 161 is dispensed using a dispensing machine. During the dispensing process, the dispensing machine cannot guarantee that the dispensing thickness is completely uniform. When the maximum thickness of the first portion 1611 is less than or equal to the distance from the second side 1211 to the first side 1221, meaning that the thickness of the first portion 1611 is consistently less than or equal to this distance, the first portion 1611 will not protrude from the second side 1211. When the user observes the interior of the electronic device 100 through the clearance notch, the first adhesive 161 will not be visible, thereby improving the product quality of the electronic device, ensuring the overall aesthetics of the electronic device 100, and enhancing the user experience.
[0068] The first colloid 161 may further include a second portion 1612, which is disposed in the second region 1223. The maximum thickness of the second portion 1612 is less than or equal to the thickness of the functional layer 123. That is, the thickness of the second portion 1612 is always less than or equal to the thickness of the functional layer 123. In other words, 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, exerting 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, leading to increased stress on the functional layer 123 and posing a risk of deformation to the functional layer 123. Therefore, by limiting the maximum thickness of the second part 1612 to be less than or equal to the thickness of the functional layer 123, the deformation of the functional layer 123 caused by the above reasons can be avoided.
[0069] The first adhesive 161 is made of hot melt adhesive. If the first adhesive 161 is damaged after prolonged use of the electronic device 100, the display screen 120 can be removed from the mid-frame 140, and then the first adhesive 161 can be heated. Since the first adhesive 161 is hot melt adhesive, it can be removed after heating and new hot melt adhesive can be applied.
[0070] In some embodiments of this application, a first portion 1611 and a second portion 1612 of the first colloid 161 are connected.
[0071] Please refer to some embodiments of this application. Figure 8 The second colloid 1621 is located on one side of the sound outlet channel 150 (e.g., Figure 8 The sound outlet channel 150 shown is on one side of the negative X-axis direction, and the third colloid 1622 is located on the other side of the sound outlet channel 150 (e.g., on the other side of the negative X-axis direction). Figure 8 The sound output channel 150 shown is on one side of the positive X-axis direction.
[0072] In this way, on the one hand, the second colloid 1621 can bypass the sound outlet channel 150, preventing the second colloid 1621 and the third colloid 1622 from blocking the sound outlet channel 150 and ensuring normal sound output from the sound outlet channel 150. On the other hand, it can reduce the amount of the second colloid 1621 and the third colloid 1622 used, thereby reducing the production cost of the electronic device 100, reducing the overall weight of the electronic device 100, and improving the user's handling experience.
[0073] Wherein, the second colloid 1621 and one end of the first colloid 161 (e.g. Figure 8The first colloid 161 shown is connected at one end in the negative X-axis direction. As a result, water that diffuses 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. As a result, water that diffuses to 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 and the other end of the first colloid 161 (for example) Figure 8 The first colloid 161 shown is connected at one end in the positive X-axis direction. As a result, water that diffuses 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. As a result, water that diffuses 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 this. Figure 8 and Figure 10 The border 141 may include a first border 1411, a second border 1412, and a third border 1413. The first border 1411 is disposed opposite to the second side 1211. One end of the first border 1411 (e.g. Figure 8 The first border 1411 shown in the diagram (at one end in the negative X-axis direction) is connected to the second border 1412, and the other end of the first border 1411 (for example) Figure 8 The first border 1411 shown in the diagram is connected to the third border 1413 at one end in the positive X-axis direction; the second colloid 1621 forms an "L"-shaped colloid; the third colloid 1622 forms an "L"-shaped colloid.
[0076] Specifically, the first protrusion includes a first sub-protrusion and a second sub-protrusion connected together. The extension direction of the first sub-protrusion is parallel to the extension direction of the first frame 1411, and the extension direction of the second sub-protrusion is parallel to the extension direction of the second frame 1412. The first sub-protrusion includes a first sub-side wall facing away from the frame 141, and the second sub-protrusion includes a second sub-side wall facing away from the frame 141. The first sub-side wall and the second sub-side wall form a first side wall 1421a. The first adhesive segment 1621a is located between the first sub-side wall and the display screen 120, and the second adhesive segment 1621b is located between the second sub-side wall and the display screen 120. The first adhesive segment 1621a and the second adhesive segment 1621b are connected at the transition position of the first frame 1411 and the second frame 1412.
[0077] The second protrusion includes a connected third sub-protrusion and a fourth sub-protrusion. The extension direction of the third sub-protrusion is parallel to the extension direction of the first frame 1411, and the extension direction of the fourth sub-protrusion is parallel to the extension direction of the third frame 1413. The third sub-protrusion includes a third sub-sidewall facing away from the frame 141, and the fourth sub-protrusion includes a fourth sub-sidewall facing away from the frame 141. The third and fourth sub-sidewalls form a second sidewall 1422a. The third adhesive 1622 includes a connected third adhesive segment 1622a and a fourth adhesive segment 1622b. The third adhesive segment 1622a is located between the third sub-sidewall and the display screen 120, and the fourth adhesive segment 1622b is located between the fourth sub-sidewall and the display screen 120. The third adhesive segment 1622a and the fourth adhesive segment 1622b are connected at the transition position between the first frame 1411 and the third frame 1413.
[0078] It should be noted that, compared to the straight fourth adhesive 163 on the first border 1411, second border 1412, and third border 1413, the connection points between the first border 1411 and the second border 1412, and between the first border 1411 and the third border 1413, are transition points, which are difficult to apply adhesive to. Setting the second adhesive 1621 as an "L"-shaped adhesive can effectively wrap the transition points between the first border 1411 and the second border 1412; setting the third adhesive 1622 as an "L"-shaped adhesive can effectively wrap the transition points between the first border 1411 and the third border 1413.
[0079] Specifically, refer to Figure 8 In this design, the frame 141 has rounded corners at the transition point, and the cover plate also has rounded corners at the transition point. The two rounded corners complement 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 precision of the connection between the cover plate and the frame at the transition point, which makes it difficult to apply the fourth adhesive 163 at the transition point and makes it impossible to guarantee the sealing of the transition point.
[0080] However, the amount of adhesive dispensed by a dispensing machine per unit time is generally fixed. Furthermore, when the fourth adhesive 163 is positioned at the transition point, the dispensing machine needs to constantly change direction. Therefore, it is difficult to guarantee the sealing performance of the fourth adhesive 163 at the transition point. By setting the "L"-shaped second adhesive 1621 and third adhesive 1622, the processing error between the frame 141 and the cover plate at the transition point can be compensated, providing a stable dispensing space for the fourth adhesive 163, thereby ensuring the stability of the fit between the cover plate and the frame 141 after the fourth adhesive 163 is dispensed.
[0081] At the same time, refer to Figure 8The arrow path indicates that the transition points between the first frame 1411 and the second frame 1412, and between the first frame 1411 and the third frame 1413, are areas where moisture from the external environment is more likely to enter the electronic device. Therefore, placing a second adhesive 1621 at the transition point between the first frame 1411 and the second frame 1412, a third adhesive 1622 at the transition point between the first frame 1411 and the third frame 1413, and then a fourth adhesive 163, can better ensure the sealing of the transition points, thereby preventing sweat and moisture from the external environment from entering the electronic device, better protecting the internal electrical components, and improving product quality.
[0082] Specifically, in some embodiments, the second colloid 1621 and the third colloid 1622 can be made of silicone. Silicone colloids have advantages such as good electrical insulation properties, resistance to aging, high adsorption capacity, good thermal stability, and stable chemical properties.
[0083] Please refer to some embodiments of this application. Figures 8 to 10 The middle frame 140 may also include a middle plate 145, with a frame 141 connected to the circumferential edge of the middle plate 145; the electronic device may also include a fifth adhesive 164, which is disposed between the display screen 120 and the middle plate 145 for bonding the display screen 120 to the middle plate 145.
[0084] The fifth colloid 164 includes a first end facing the sound outlet channel, the second colloid 1621 is sealed to the first end of the fifth colloid 164, and the third colloid 1622 is sealed to the first end of the fifth colloid 164.
[0085] Specifically, on the one hand, the middle plate 145 includes a support surface 1451 facing the display screen 120, and a fifth colloid 164 is disposed on one side surface of the display screen 120 facing the support surface 1451. By disposing of 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 prevent the formation of gaps between the second colloid 1621 and the fifth colloid 164, and prevent the formation of gaps between the third colloid 1622 and the fifth colloid 164. This prevents water stains in the environment from entering the space between the display screen 120 and the middle plate 145 through the gaps between the second colloid 1621 and the fifth colloid 164, and the gaps between the third colloid 1622 and the fifth colloid 164, thus affecting the normal use of the electronic device.
[0087] In some embodiments of this application, the fourth colloid 163 and the fifth colloid 164 can also be made of hot melt adhesive. Thus, when maintenance is required on the internal components of the electronic device during long-term use, heating the fourth colloid 163 is sufficient to separate the display screen 120 from the frame 141, and heating the fifth colloid 164 is sufficient to separate the display screen 120 from the mid-frame 140, allowing for internal maintenance of the electronic device.
[0088] Please continue reading. Figure 10 The path indicated by the arrow, from the sound outlet channel 150, allows sweat and water stains to enter and diffuse onto the functional layer 123 on the side opposite to the cover plate 121. This is blocked by the fifth colloid 164, further preventing water stains entering through the sound outlet channel 150 from entering the interior of the electronic device. Thus, the first colloid 161, the second colloid 1621, the third colloid 1622, the fourth colloid 163, and the fifth colloid 164, working in concert, provide better protection for the electronic device.
[0089] In some embodiments of this application, please refer to Figure 11 , Figure 11 This is a partial schematic diagram of the mid-frame provided in other embodiments of this application. A first clearance space 143 is provided between the first boss 1421 and the sound outlet channel 150, and a second clearance space 144 is provided between the second boss 1422 and the sound outlet channel 150. The first boss 1421 is located on one side of the sound outlet channel 150 (e.g., Figure 11 The sound output channel 150 shown is on one side of the negative X-axis direction. The first boss 1421 is a certain distance away from the sound output channel 150 and no boss is provided. The space between the first boss 1421 and the sound output channel 150 is the first clearance space 143.
[0090] Similarly, the second protrusion 1422 is located on the other side of the sound outlet channel 150 (e.g., Figure 11 The sound output channel 150 shown is on one side of the positive X-axis direction. The second boss 1422 is a certain distance away from the sound output channel 150 and no boss is provided. The space between the second boss 1422 and the sound output channel 150 is the second clearance 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 clearance space 143. The provision of the first clearance space 143 increases the placement space of the first colloid, the second colloid, and the fourth colloid in the first clearance space 143, thereby increasing the quantity of the first colloid, the second colloid, and the fourth colloid in the first clearance space 143. This, in turn, increases the stability of the connection between the first colloid, the second colloid, and the fourth colloid, ensuring the sealing between the first colloid, the second colloid, and the fourth colloid, and preventing water stains from the external environment from entering the electronic device through the connection position of the first colloid, the second colloid, and the fourth colloid.
[0092] The first, third, and fourth colloids are connected at the location of the second clearance space 143. The second clearance space 143 increases the space for the first, third, and fourth colloids to be installed in the second clearance space 144, thereby increasing the stability of the connection between the first, third, and fourth colloids in the second clearance space 144, ensuring the sealing between the first, third, and fourth colloids, and preventing water stains from the external environment from entering the electronic device through the connection location of the first, third, and fourth colloids.
[0093] In this way, on the one hand, setting the first clearance space 143 can improve the connection strength between the second colloid 1621, the first colloid 161, and the fourth colloid 163; setting the second clearance 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 setting the first clearance space 143 and the second clearance space 144, users can avoid seeing the protrusion through the clearance notch when using the electronic device, thereby improving the overall aesthetics of the electronic device and enhancing the user experience.
[0094] For specific dispensing procedures, please refer to [link / reference]. Figure 12 and Figure 13 , Figure 12 This is a schematic diagram illustrating the dispensing of a first colloid onto a display screen in other embodiments of this application; Figure 13 This is a schematic diagram illustrating the application of a second, third, and fourth colloid to the middle frame in other embodiments of this application. First, the first colloid 161 is applied to a corresponding position on the display screen 120; second, the second colloid 1621 and the third colloid 1622 are applied to corresponding positions on the middle frame 140; third, the fourth colloid 163 is applied to a corresponding position on the middle frame 140; finally, the display screen 120 is mounted onto the middle frame 140. A fifth colloid 164 is also provided between the display screen 120 and the middle frame 140.
[0095] Therefore, by setting up a first colloid 161, a second colloid 1621, a third colloid 1622, a fourth colloid 163, and a fifth colloid 164 that cooperate with each other, wherein the second colloid 1621 is connected to the first colloid 161, the fourth colloid 163, and the fifth colloid 164; and the third colloid 1622 is connected to the first colloid 161, the fourth colloid 163, and the fifth colloid 164, comprehensive protection is provided for the electronic device, preventing moisture from the external environment from entering the internal components and preventing corrosion of the internal electronic components.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
