Description

Technical Field

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

[0002] With changing consumer attitudes, the pursuit of large screen-to-body ratios in electronic devices has become a technological development trend. For organic light-emitting diode (OLED) screens, due to packaging process requirements, sufficient packaging space needs to be left on the side of the cover plate corresponding to the bend of the screen's COP (chip on plastic) to allow for the wiring. This results in uneven black border dimensions around the cover plate, affecting the aesthetic appearance of the electronic device. Summary of the Invention

[0003] This application provides an electronic device that can reduce the size of the black border at the bottom of the electronic device, increase the screen ratio of the electronic device, and thus improve the aesthetic appearance of the electronic device.

[0004] This application provides an electronic device, including a housing and a screen. The housing has a mounting groove. The screen includes a display panel and a cover plate covering the display panel. The display panel includes a bent portion. The cover plate includes a first peripheral portion and a second peripheral portion connected to the first peripheral portion, both of which are mounted in the mounting groove. The first peripheral portion is in the shape of a bent plate and includes a first end face, which is an inner inclined surface. That is, the first end face is a surface inclined towards the inside of the cover plate.

[0005] The second perimeter corresponds to the bent portion and includes a second end face and a first transition arc surface. The second end face is an outwardly inclined surface, that is, the second end face is a surface that slopes towards the outside of the cover plate. The first transition arc surface connects the second end face and the first end face, enabling a smooth transition between the second end face and the first end face, avoiding collisions between the cover plate and the housing during installation, and ensuring the reliability of the electronic device. The second end face covers at least a portion of the first transition arc surface. That is, along the thickness direction of the cover plate, the second end face and the first transition arc surface at least partially overlap.

[0006] The projection of the sidewall of the mounting groove onto the bottom wall of the mounting groove covers at least a portion of the projection of the second end face onto the bottom wall of the mounting groove, or the projection of the sidewall of the mounting groove onto the bottom wall of the mounting groove and the projection of the second end face onto the bottom wall of the mounting groove are spaced apart. The electronic device also includes an adhesive layer that is connected between the sidewall of the mounting groove and the second end face and covers at least a portion of the second end face.

[0007] When users view electronic devices, because at least part of the second end face is blocked by the side wall of the mounting slot or the adhesive layer, the visual point will move from the edge of the cover plate to the middle of the cover plate. This is equivalent to reducing the width of the black border in the area corresponding to the bend of the screen. This not only helps to achieve uniformity of the black border around the screen, but also increases the screen ratio and improves the aesthetic appearance of the electronic device.

[0008] In one embodiment, the second perimeter includes a connecting portion and a mounting portion. The connecting portion is connected to the first perimeter, and the mounting portion is located outside the connecting portion and connected to the connecting portion. The mounting portion includes a second end face.

[0009] The width of the mounting part is smaller than that of the connecting part. The side of the mounting part and the end face of the connecting part together form a first transition arc surface. The second end face and the top surface of the connecting part together cover the first transition arc surface. Specifically, the second end face covers a portion of the first transition arc surface, and the top surface of the connecting part covers a portion of the first transition arc surface.

[0010] Alternatively, the width of the mounting part is equal to that of the connecting part, the side of the mounting part is a first transition arc surface, and the second end face covers the first transition arc surface.

[0011] In one embodiment, the mounting groove includes a sub-mounting groove and an overflow groove. The overflow groove communicates with the sub-mounting groove and extends from the groove sidewall of the sub-mounting groove toward the outside of the housing. A second periphery is mounted in the sub-mounting groove. Part of the adhesive layer is located in the overflow groove, and part of the adhesive layer is located in the sub-mounting groove, and is connected between the second periphery and the housing.

[0012] During dispensing, excess glue can flow into the overflow tank, preventing excessive glue from overflowing and affecting the display panel's display.

[0013] In one embodiment, the cross-section of the overflow groove is circular, square, or trapezoidal to adapt to different process requirements.

[0014] In one embodiment, the cover plate further includes a third periphery connected to the end of the second periphery away from the first periphery. The third periphery is in the shape of a bent plate and includes a third end face, which is an inwardly inclined surface. That is, the third end face is a surface inclined towards the inside of the cover plate. The second periphery also includes a second transition arc surface connected between the second end face and the third end face, with the second end face covering at least a portion of the second transition arc surface. That is, along the thickness direction of the cover plate, the second end face and the second transition arc surface at least partially overlap.

[0015] Both the first and third perimeters are shaped like bent plates, giving the cover a 3D curved shape on both sides, which enhances the aesthetic appeal of the cover and, consequently, the electronic device. Simultaneously, the second transition arc surface connects the second and third end faces, ensuring a smooth transition between them, preventing bumps and knocks during cover installation, and guaranteeing the reliability of the electronic device.

[0016] In one embodiment, the cover plate further includes a fourth perimeter, which is connected between the first perimeter and the third perimeter, and the fourth perimeter includes a fourth end face, which is an inner bevel or a straight face.

[0017] In one embodiment, both the second and fourth circumferences are planar plates, so that the cover plate is a 3D plate with curved sides. Alternatively, both the second and fourth circumferences are bent plates, so that the cover plate is a 3D plate with curved sides, thereby increasing the aesthetic appeal of the cover plate and thus increasing the aesthetic appeal of the electronic device.

[0018] In one embodiment, the cover plate further includes a central portion, and a first peripheral portion, a second peripheral portion, a third peripheral portion, and a fourth peripheral portion are all arranged around the central portion and connected to the central portion, the central portion being in the form of a flat plate or a bent plate.

[0019] In one embodiment, the first perimeter, second perimeter, third perimeter, fourth perimeter, and middle portion are integrally formed to increase the overall strength of the cover plate.

[0020] In one embodiment, the tilt angle of the second end face is greater than or equal to 30° and less than 90°.

[0021] In one embodiment, the tilt angle of the first end face is greater than or equal to 0° and less than or equal to 30°, which can prevent the first periphery from undergoing thermal bending deformation during the processing of the cover plate and ensure the assembly effect of the cover plate in electronic devices.

[0022] In one embodiment, the bent portion is located at the lower end of the display panel, the cover plate is square, and the second perimeter is located at the lower end of the cover plate.

[0023] In one embodiment, the projection distance of the second periphery on the bottom wall of the mounting groove is greater than or equal to 0. Attached Figure Description

[0037] The technical solutions in the embodiments of this application will be described below with reference to the accompanying drawings.

[0038] Please see Figure 1 , Figure 1This is a schematic diagram of the structure of an electronic device 100 provided in an embodiment of this application.

[0039] Electronic device 100 can be a mobile phone, tablet computer, laptop computer, point of sale terminal (POS machine), or wearable device, or other electronic product with display function. Wearable devices can include smart bracelets, smartwatches, augmented reality (AR) glasses, virtual reality (VR) glasses, etc. This application embodiment uses a mobile phone as an example for illustration.

[0040] For ease of description, 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 height direction of the electronic device 100 is defined as the Z-axis direction. The X-axis direction, Y-axis direction, and Z-axis direction are all perpendicular to each other.

[0041] Please refer to the following: Figure 2 . Figure 2 yes Figure 1 An exploded view of the electronic device 100 shown.

[0042] In this embodiment, the electronic device 100 includes a screen 110 and a housing 120. The screen 110 is mounted on the top side of the housing 120. The housing 120 includes a mid-frame 30 and a back cover (not shown), with the back cover mounted on the bottom side of the mid-frame 30. The screen 110 is mounted on the top side of the mid-frame 30, meaning that the screen 110 and the back cover are respectively fixed to opposite sides of the mid-frame 30.

[0043] It should be noted that, in describing the electronic device 100 in this application, the directional terms such as "top" and "bottom" used are mainly based on the electronic device 100's location within the attached... Figure 1 The orientation of the electronic device 100 is described in the diagram, with the positive direction of the Z-axis as "top" and the negative direction of the Z-axis as "bottom". This does not limit the orientation of the electronic device 100 in actual application scenarios.

[0044] Please see Figure 2 and Figure 3 , Figure 3 yes Figure 1 A cross-sectional view of the screen 110 in the electronic device 100 shown.

[0045] The screen 110 includes a display panel 10 and a cover plate 20, which covers the display panel 10 to protect it. The display panel 10 is an OLED display panel. The display panel 10 has a display surface for displaying images, text, or numbers. The display panel 10 includes a bent portion 11, which is formed by the display panel 10 using a COP (Chip-on-Plastic) packaging process. For example, the bent portion 11 is located at the lower end of the display panel 10. It is understood that using the COP packaging process for the display panel 10 can reduce the non-display area of ​​the screen 110, which is beneficial for improving the screen-to-body ratio of the screen 110. In some other embodiments, the bent portion 11 may also be located at the upper, left, or right end of the display panel 10, and this application does not specifically limit this.

[0046] It should be noted that, in describing the electronic device 100 in this application, the directional terms such as "up," "down," "left," and "right" used are mainly based on the electronic device 100's location within the attached device. Figure 1 The orientation of the electronic device 100 is described in the diagram, with the positive Y-axis direction as "up", the negative Y-axis direction as "down", the positive X-axis direction as "right", and the negative X-axis direction as "left". This does not constitute a limitation on the orientation of the electronic device 100 in the actual application scenario.

[0047] Please see Figure 4 , Figure 4 yes Figure 3 A schematic diagram of the structure of the cover plate 20 in the screen 110 shown.

[0048] Cover plate 20 covers display panel 10. In this embodiment, cover plate 20 may be a glass cover plate. Exemplarily, cover plate 20 is square. Cover plate 20 includes a first peripheral portion 21, a second peripheral portion 22, a third peripheral portion 23, a fourth peripheral portion 24, and a central portion 25. The central portion 25 is located in the middle of cover plate 20 and is square. The first peripheral portion 21, the second peripheral portion 22, the third peripheral portion 23, and the fourth peripheral portion 24 are all located on the periphery of cover plate 20 and are all connected to the central portion 25. Among them, the first peripheral portion 21 is located at the left end of cover plate 20, the second peripheral portion 22 is located at the lower end of cover plate 20, the third peripheral portion 23 is located at the right end of cover plate 20, and the fourth peripheral portion 24 is located at the upper end of cover plate 20.

[0049] Specifically, the first peripheral portion 21, the second peripheral portion 22, the third peripheral portion 23, and the fourth peripheral portion 24 are respectively connected to the four sides of the central portion 25. The second peripheral portion 22 and the fourth peripheral portion 24 are spaced apart and opposite to each other, while the first peripheral portion 21 and the third peripheral portion 23 are spaced apart and opposite to each other. That is, the first peripheral portion 21, the second peripheral portion 22, the third peripheral portion 23, and the fourth peripheral portion 24 are all arranged around the central portion 25 and connected to it. Among them, the first peripheral portion 21 is connected to the left end of the central portion 25, the second peripheral portion 22 is connected to the lower end of the central portion 25, the third peripheral portion 23 is connected to the right end of the central portion 25, and the fourth peripheral portion 24 is connected to the upper end of the central portion 25. For example, the central portion 25, the first peripheral portion 21, the second peripheral portion 22, the third peripheral portion 23, and the fourth peripheral portion 24 are integrally formed to increase the overall strength of the cover plate 20.

[0050] Please see Figure 5 . Figure 5 yes Figure 4 The diagram shows a cross-sectional view of the cover plate 20 cut along direction II.

[0051] In this embodiment, the central portion 25 is a planar plate, while the first peripheral portion 21 and the third peripheral portion 23 are bent plates. The cover plate 20 has an axis of symmetry P, and the first peripheral portion 21 and the third peripheral portion 23 are mirror-symmetrical about the P axis. The axis of symmetry P is parallel to the Z-axis, and both the first peripheral portion 21 and the third peripheral portion 23 bend and protrude in the positive Z-axis direction. Specifically, the first peripheral portion 21 extends from the left end of the central portion 25 along the negative X-axis direction and bends and protrudes in the positive Z-axis direction. The third peripheral portion 23 extends from the right end of the central portion 25 along the positive X-axis direction and bends and protrudes in the positive Z-axis direction.

[0052] In some other embodiments, the central portion 25 may also be in the form of a bent plate. In this case, the central portion 25 bends and protrudes in the positive Z-axis direction to increase the aesthetic appeal of the cover plate 20, thereby increasing the aesthetic appeal of the electronic device 100.

[0053] The first perimeter 21 includes a first end face 1a away from the center portion 25, and the third perimeter 23 includes a third end face 1c away from the center portion 25. In this embodiment, both the first end face 1a of the first perimeter 21 and the third end face 1c of the third perimeter 23 are inwardly inclined surfaces. That is, both the first end face 1a of the first perimeter 21 and the third end face 1c of the third perimeter 23 are inclined surfaces that slope inward toward the cover plate 20, and the angles they make with the Z-axis are both acute angles.

[0054] The inclination angle of the first end face 1a of the first perimeter 21 is the first slope angle α. That is, the angle between the first end face 1a of the first perimeter 21 and the Z-axis is the first slope angle α. The inclination angle of the third end face 1c of the third perimeter 23 is the second slope angle β. That is, the angle between the third end face 1c of the third perimeter 23 and the Z-axis is the second slope angle β. The angles of the first slope angle α and the second slope angle β are both greater than or equal to 10° and less than or equal to 15°. By setting the first end face 1a of the first perimeter 21 and the third end face 1c of the third perimeter 23 as inner slopes, and designing the angles of the first slope angle α and the second slope angle β to be between 10° and 15°, thermal bending deformation during the processing of the cover plate 20 can be avoided, ensuring the assembly effect of the cover plate 20 in the electronic device 100. In some other embodiments, the angles of the first slope angle α and the second slope angle β may both be greater than or equal to 0° and less than or equal to 30°, or the first end face 1a and the third end face 1c may also be planes parallel to the Z-axis direction.

[0055] Please see Figure 1 and Figure 6 . Figure 6 yes Figure 4 The diagram shows a cross-sectional view of the cover plate 20 cut along the II-II direction.

[0056] Both the second perimeter 22 and the fourth perimeter 24 are planar plates, making the cover plate 20 a 3D plate with curved sides, thus improving the aesthetics of the electronic device 100. Specifically, the second perimeter 22 extends from the lower end of the middle portion 25 towards the negative Y-axis, and the fourth perimeter 24 extends from the upper end of the middle portion 25 towards the positive Y-axis. The fourth perimeter 24 includes a fourth end face 1d away from the middle portion 25, and the fourth end face 1d of the fourth perimeter 24 is an inner inclined surface. That is, the fourth end face 1d of the fourth perimeter 24 is an inclined surface that slopes inward toward the inside of the cover plate 20, and the angle between it and the Z-axis is an acute angle. The inclination angle of the fourth end face 1d of the fourth perimeter 24 is a third slope angle γ. That is, the angle between the fourth end face 1d of the fourth perimeter 24 and the Z-axis is the third slope angle γ. The angle of the third slope angle γ is greater than or equal to 10° and less than or equal to 15°. In some other embodiments, the angle of the third slope angle γ may be greater than or equal to 0° and less than or equal to 30°, or the fourth end face 1d may be a plane parallel to the Z-axis direction. That is, the fourth end face 1d is an inner inclined surface or a straight surface.

[0057] In some other embodiments, the second perimeter 22 and the fourth perimeter 24 may also be in the form of bent plates. In this case, both the second perimeter 22 and the fourth perimeter 24 are bent and protruded in the positive Z-axis direction. Specifically, the second perimeter 22 extends from the lower end of the middle portion 25 along the negative Y-axis direction and bends and protrudes in the positive Z-axis direction. The fourth perimeter 24 extends from the upper end of the middle portion 25 along the positive Y-axis direction and bends in the positive Z-axis direction, so that the cover plate 20 is a 3D plate with four curved sides, further improving the aesthetics of the electronic device 100.

[0058] Furthermore, the top surface of the second perimeter 22 is curved, making the second perimeter 22 a 2.5D plate shape. In some other embodiments, the top surface of the second perimeter 22 may also be flat. It should be noted that this application does not specifically limit the shape of the top surface of the second perimeter 22.

[0059] Please see Figure 4 The second perimeter 22 includes a second end face 1b, a first transition arc surface 3a, and a second transition arc surface 3b. The second end face 1b is an outwardly inclined surface. That is, the second end face 1b is an inclined surface that slopes towards the outside of the cover plate 20. The angle between the second end face 1b and the Z-axis is an acute angle. A fourth slope angle is formed between the second end face 1b and the bottom surface of the second perimeter 22, and the angle of the fourth slope angle is greater than or equal to 30° and less than 90°. The fourth slope angle is opposite in orientation to the first slope angle, that is, the inclination direction of the third end face 1c of the third perimeter 23 is opposite to the inclination direction of the second end face 1b of the second perimeter 22.

[0060] A first transition arc surface 3a connects the first end face 1a and the second end face 1b. A second transition arc surface 3b connects the second end face 1b and the third end face 1c. The second end face 1b covers at least a portion of the first transition arc surface 3a and at least a portion of the second transition arc surface 3b. That is, along the Z-axis direction, the second end face 1b at least partially overlaps with the first transition arc surface 3a and the second transition arc surface 3b.

[0061] In this embodiment, the second perimeter 22 includes a mounting portion 2 and a transition portion 3 located away from the middle portion 25. The transition portion 3 connects the middle portion 25 and the mounting portion 2, and also connects the first perimeter 21 and the third perimeter 23. The mounting portion 2 is connected to the end face of the transition portion 3 and protrudes relative to the lower end of the third perimeter 23 and the lower end of the first perimeter 21. The top surface of the mounting portion 2 forms a second end face 1b.

[0062] In this embodiment, along the X-axis, the width of the mounting portion 2 is smaller than the width of the transition portion 3. Both the left and right sides of the mounting portion 2 are curved surfaces, and the end face of the transition portion 3 is also curved. The left side of the mounting portion 2 smoothly transitions to the end face of the transition portion 3 to form a first transition curved surface 3a, and the right side of the mounting portion 2 smoothly transitions to the end face of the transition portion 3 to form a second transition curved surface 3b. At this time, the second end face and the top surface of the transition portion 3 completely cover the first transition curved surface 3a and the second transition curved surface 3b. The first transition curved surface 3a and the second transition curved surface 3b are mirror-symmetrical about the axis of symmetry P.

[0063] In some other embodiments, the width of the mounting portion 2 along the X-axis can be equal to the width of the transition portion 3. In this case, the second end face 1b completely covers the first transition arc surface 3a and the second transition arc surface 3b.

[0064] The first end face 1a of the first perimeter 21 is smoothly connected to the second end face 1b of the second perimeter 22 via a first transition arc surface 3a. Thus, in the X-axis direction, the first end face 1a of the first perimeter 21 and the second end face 1b of the second perimeter 22, which have opposite inclination directions, can be smoothly connected via the first transition arc surface 3a. The second end face 1b of the second perimeter 22 is smoothly connected to the third end face 1c of the third perimeter 23 via a second transition arc surface 3b. Thus, in the X-axis direction, the second end face 1b of the second perimeter 22 and the third end face 1c of the third perimeter 23, which have opposite inclination directions, can be smoothly connected via the second transition arc surface 3b. The smooth connection between the second end face 1b of the second perimeter 22, the third end face 1c of the third perimeter 23, and the first end face 1a of the first perimeter 21 makes the four corners of the cover plate 20 rounded. This disperses the stress points when the four corners of the cover plate 20 are subjected to external forces, improving the overall strength of the cover plate 20 and protecting the display panel 10. Meanwhile, the smooth transition of each surface of the cover plate 20 can prevent collisions between the cover plate 20 and the middle frame 30 during installation, ensuring the reliability of the electronic device 100.

[0065] Please see Figure 7 . Figure 7 yes Figure 1 The diagram shows the structure of the middle frame of the electronic device 100. The width of the middle frame 30 is along the X-axis, the length is along the Y-axis, and the height is along the Z-axis.

[0066] The middle frame 30 is provided with a mounting slot for mounting the screen 110. That is, the screen 110 is mounted in the mounting slot. The cover plate 20 is also mounted in the mounting slot. In this embodiment, the middle frame 30 includes a first side frame 31, a second side frame 32, a third side frame 33, a fourth side frame 34, and a middle plate 35. The middle plate 35 is located in the middle of the middle frame 30, and the first side frame 31, second side frame 32, third side frame 33, and fourth side frame 34 are respectively connected to the four sides of the middle plate 35. Along the Y-axis, the first side frame 31 and the third side frame 33 are spaced apart and opposite to each other; along the X-axis, the second side frame 32 and the fourth side frame 34 are spaced apart and opposite to each other. Specifically, the first side frame 31 is connected to the lower end of the middle plate 35, the second side frame 32 is connected to the left end of the middle plate 35, the third side frame 33 is connected to the upper end of the middle plate 35, and the fourth side frame 34 is connected to the right end of the middle plate 35. For example, the first frame 31, the second frame 32, the third frame 33, the fourth frame 34 and the middle plate 35 are integrally formed to increase the overall strength of the middle frame 30.

[0067] The first frame 31 and the third frame 33 extend along the X-axis and are both connected between the second frame 32 and the fourth frame 34. Specifically, the second frame 32 includes a first bend 32b, a second bend 32c, and a first connecting portion 32d, with the first bend 32b and the second bend 32c located at opposite ends of the first connecting portion 32d. One end of the first bend 32b is connected to the first connecting portion 32d, and the other end is connected to the first frame 31. One end of the second bend 32c is connected to the first connecting portion 32d, and the other end is connected to the third frame 33. The fourth frame 34 includes a third bend 34b, a fourth bend 34c, and a second connecting portion 34d, with the third bend 34b and the fourth bend 34c located at opposite ends of the second connecting portion 34d. One end of the third bend 34b is connected to the second connecting portion 34d, and the other end is connected to the third frame 33. One end of the fourth bend 34c is connected to the second connecting part 34d, and the other end is connected to the first frame 31.

[0068] For example, the first bend 32b, the second bend 32c and the first connecting portion 32d of the second frame 32 are integrally formed, and the third bend 34b, the fourth bend 34c and the second connecting portion 34d of the fourth frame 34 are integrally formed to increase the overall connection strength between the second frame 32 and the fourth frame 34.

[0069] Please refer to the following: Figure 8 and Figure 9 . Figure 8 yes Figure 7 The diagram shows a cross-sectional view of the middle frame 30 cut along the III-III direction. Figure 9 yes Figure 7 The diagram shows a cross-sectional view of the middle frame 30 cut along the IV-IV direction.

[0070] Please refer to the following: Figure 2 The first frame 31 has a first mounting slot 31a, the second frame 32 has a second mounting slot 32a, the third frame 33 has a third mounting slot 33a, and the fourth frame 34 has a fourth mounting slot 34a. The first mounting slot 31a communicates with the second mounting slot 32a, the third mounting slot 33a communicates with the second mounting slot 32a and the fourth mounting slot 34a, and the fourth mounting slot 34a communicates with the first mounting slot 31a. That is, the first mounting slot 31a, the second mounting slot 32a, the third mounting slot 33a, and the fourth mounting slot 34a are connected sequentially to form a mounting slot for mounting the screen 110. The cover plate 20 of the screen 110 is mounted in the mounting slot, and the display panel 10 of the screen 110 is located between the cover plate 20 and the middle plate 35.

[0071] Please refer to the following: Figure 4Specifically, the opening of the first mounting groove 31a is located on the top surface of the first frame 31. In the Z-axis direction, the first mounting groove 31a is recessed from the top surface of the first frame 31 to the bottom surface and penetrates the inner surface of the first frame 31. The first mounting groove 31a is adapted to the second periphery 22 of the cover plate 20, allowing the second periphery 22 to be mounted within the first mounting groove 31a.

[0072] The opening of the second mounting groove 32a is located on the top surface of the second frame 32. In the Z-axis direction, the second mounting groove 32a is recessed from the top surface of the second frame 32 to the bottom surface and extends through the inner surface of the second frame 32. The second mounting groove 32a is adapted to the first periphery 21 of the cover plate 20, and the second mounting groove 32a can be adaptively fitted to the first periphery 21, so that the first periphery 21 can be installed in the second mounting groove 32a.

[0073] The opening of the third mounting groove 33a is located on the top surface of the third frame 33. In the Z-axis direction, the third mounting groove 33a is recessed from the top surface of the third frame 33 to the bottom surface and penetrates the inner surface of the third frame 33. The third mounting groove 33a is adapted to the fourth perimeter 24 of the cover plate 20, and the third mounting groove 33a can be adaptively fitted with the fourth perimeter 24, so that the fourth perimeter 24 can be installed in the third mounting groove 33a.

[0074] The opening of the fourth mounting groove 34a is located on the top surface of the fourth frame 34. In the Z-axis direction, the fourth mounting groove 34a is recessed from the top surface of the fourth frame 34 to the bottom surface and penetrates the inner surface of the fourth frame 34. The fourth mounting groove 34a is adapted to the third periphery 23 of the cover plate 20, and the fourth mounting groove 34a can be adaptively fitted to the third periphery 23, so that the third periphery 23 can be installed in the fourth mounting groove 34a.

[0075] Please see Figure 4 , Figure 7 and Figure 9 The first mounting groove 31a further includes a first transition groove 31b and a second transition groove 31c. The first transition groove 31b and the second transition groove 31c are located at opposite ends of the first mounting groove 31a. The first transition groove 31b connects to the second mounting groove 32a, and the second transition groove 31c connects to the fourth mounting groove 34a. The second peripheral portion 22 is mounted in the first mounting groove 31a. Specifically, the first transition groove 31b is adapted to the first transition arc surface of the second peripheral portion 22, and the second transition groove 31c is adapted to the second transition arc surface of the second peripheral portion 22. This allows the first transition groove 31b and the second transition groove to be adaptively fitted to both ends of the second peripheral portion 22, with the left end of the second peripheral portion 22 mounted in the first transition groove 31b and the right end of the second peripheral portion 22 mounted in the second transition groove 31c.

[0076] Please see Figure 10 . Figure 10 yes Figure 1 The diagram shows a cross-sectional view of the electronic device 100 taken along the MM line in the first embodiment.

[0077] The first mounting groove 31a also includes an overflow groove 101 and a sub-mounting groove 101a, with the overflow groove communicating with the sub-mounting groove 101a. The overflow groove 101 extends from the groove sidewall of the sub-mounting groove 101a toward the outer side of the housing 120. The second peripheral portion 22 is mounted in the sub-mounting groove 101a, which communicates between the second mounting groove 32a and the fourth mounting groove 34a. For example, the overflow groove 101 has an arc-shaped cross-section. Specifically, the opening of the overflow groove 101 is located on the groove sidewall of the first mounting groove 31a. The overflow groove 101 is recessed from the groove sidewall of the first mounting groove 31a toward the outer side of the first frame 31.

[0078] In some other embodiments, the cross-section of the overflow groove 101 may also be a square groove, a trapezoidal groove, or a triangular groove, etc. The shape of the overflow groove 101 is not specifically limited in the embodiments of this application.

[0079] In this embodiment, the cover plate 20 is assembled with the middle frame 30 in a non-overlapping manner. Specifically, the cover plate 20 is installed in the mounting groove of the middle frame 30. The projection of the sidewall of the mounting groove onto the bottom wall of the mounting groove and the projection of the second end face 1b onto the bottom wall of the mounting groove are spaced apart. In other embodiments, the cover plate 20 can also be assembled with the middle frame 30 in an overlapping manner. In this case, the projection of the sidewall of the mounting groove onto the bottom wall of the mounting groove covers at least a portion of the projection of the second end face 1b onto the bottom wall of the mounting groove.

[0080] The electronic device 100 also includes an adhesive layer 102, which connects the second peripheral portion 22 and the middle frame 30. Specifically, the adhesive layer 102 is located in the sub-mounting groove 101a and connects the second peripheral portion 22 and the housing 120. Specifically, the adhesive layer 102 connects between the second end face 1b of the second peripheral portion 22 and the groove wall of the first mounting groove 31a, and covers the second end face 1b. Furthermore, the adhesive layer 102 also connects between the bottom surface of the second peripheral portion 22 and the groove wall of the first mounting groove 31a, enabling assembly between the second peripheral portion 22 and the first mounting groove 31a. The angle of the fourth slope angle Ω can match the shape of the overflow groove 101, allowing the second peripheral portion 22 to be mounted on the middle frame 30 via the adhesive layer 102.

[0081] When the second periphery 22 of the cover plate 20 is installed on the middle frame 30 with glue, the excess glue can flow into the glue overflow groove 101. After the glue is cured, it forms an adhesive layer 102. The glue overflow groove 101 can prevent glue from overflowing during the glue application process and affecting the display effect of the screen 110.

[0082] Furthermore, the projection distance of the second peripheral portion 22 onto the bottom wall of the first mounting groove 31a is L1. L1 is greater than or equal to 0.5 mm to ensure that the bottom surface of the second peripheral portion 22 can be firmly adhered to the bottom wall of the first mounting groove 31a, thereby improving the assembly stability of the cover plate 20 and the middle frame 30, ensuring stable support of the middle frame 30 for the cover plate 20, and improving the assembly stability of the electronic device 100. In some other embodiments, the projection distance L1 of the second peripheral portion 22 onto the bottom wall of the first mounting groove 31a may also be greater than or equal to 0.

[0083] In this embodiment, the adhesive layer 102 covers the second end face 1b. In some other embodiments, the adhesive layer 102 may also cover part of the second end face 1b, and when the user views the electronic device 100, the visual point is located at the boundary point 5 between the first adhesive layer 102 and the cover plate 20. Compared to the prior art, where the visual point is located at the edge of the cover plate 20, in this embodiment, the visual point of the electronic device 100 is shifted to the middle of the cover plate 20, which is equivalent to reducing the width of the black border at the bottom of the screen 110. This not only helps to achieve uniformity of the black border around the electronic device 100, but also effectively increases the screen-to-body ratio of the electronic device 100, thus improving the aesthetic appearance of the electronic device 100.

[0084] Please see Figure 11 . Figure 11 yes Figure 1 The diagram shows a cross-sectional view of the electronic device 100 taken along line NN.

[0085] In this embodiment, the assembly structures of the first perimeter 21 and the second border 32, the third perimeter 23 and the fourth border 34, and the fourth perimeter 24 and the third border 33 are the same. Next, taking the assembly structure of the fourth perimeter 24 and the third border 33 as an example, the assembly structures of the first perimeter 21 and the second border 32, the third perimeter 23 and the fourth border 34, and the fourth perimeter 24 and the third border 33 will be described.

[0086] The cover plate 20 of the screen 110 is mounted on the mid-frame 30. Specifically, the fourth periphery 24 of the cover plate 20 is mounted to the third mounting groove 33a via an adhesive layer 103, and the adhesive layer 103 connects the bottom wall of the third mounting groove 33a and the bottom surface of the fourth periphery 24. The angle of the third bevel angle γ of the fourth end face 1d matches the shape of the third mounting groove 33a, so that the fourth periphery 24 can be mounted to the third mounting groove 33a of the mid-frame 30 via the adhesive layer 103.

[0087] Please see Figure 12 . Figure 12 yes Figure 1 The diagram shows a cross-sectional view of the electronic device 100 taken along the MM line in the second embodiment.

[0088] The electronic device 100 shown in this embodiment differs from the electronic device 100 shown in the first embodiment in that the cover plate 20 is assembled with the middle frame 30 by an inverted snap-fit ​​method. Specifically, the cover plate 20 is installed in the mounting groove of the middle frame 30. The projection of the sidewall of the mounting groove onto the bottom wall of the mounting groove at least partially overlaps with the projection of the second end face 1b onto the bottom wall of the mounting groove. Specifically, the adhesive layer 102 connects the bottom surface of the second peripheral portion 22 and the bottom wall of the first mounting groove 31a, so that the cover plate 20 can be installed on the middle frame 30 through the adhesive layer 102, thereby achieving an inverted snap-fit ​​assembly between the cover plate 20 and the middle frame 30.

[0089] Furthermore, the sidewall of the first mounting groove 31a partially obscures the second end face 1b. The sidewall of the first mounting groove 31a abuts against the second end face 1b. When a user views the electronic device 100, the visual point of the screen 110 falls at the point 7 where the second end face 1b abuts against the first mounting groove 31a. Compared to the prior art where the visual point of the screen 110 is located at the edge of the cover plate 20, in this embodiment, the visual point of the screen 110 is shifted to the center of the cover plate 20, effectively reducing the width of the black border at the bottom of the screen 110. This not only helps to achieve uniformity of the black border around the electronic device 100 but also increases the screen-to-body ratio, improving the aesthetic appearance of the electronic device 100.

[0090] In some other embodiments, the electronic device 100 may further include a sealant (not shown) located between the second end face 1b and the first mounting groove 31a. The visual point of the screen 110 will fall at the junction of the sealant and the second end face 1b, thereby further shifting the visual point towards the center of the cover plate 20. This effectively reduces the width of the black border at the bottom of the screen 110, which not only helps to achieve uniformity of the black border around the electronic device 100, but also effectively increases the screen-to-body ratio of the electronic device 100, improving its aesthetic appearance. Simultaneously, it improves the sealing performance of the electronic device 100.

[0091] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art will understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of this application are still within the scope of this application.
